Regulation of Fuels and Fuel Additives: Renewable Fuel Standard 
Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: Under the Clean Air Act, as amended by Section 1501 of the 
Energy Policy Act of 2005, the Environmental Protection Agency is 
required to promulgate regulations implementing a renewable fuel 
program. The statute specifies the total volume of renewable fuel that 
needs to be used in each year, with the total volume increasing over 
time. In this context, it is expected to simultaneously reduce 
dependence on foreign sources of petroleum, increase domestic sources 
of energy, and help us make progress in moving beyond a petroleum-based 
economy. The increased use of renewable fuels such as ethanol and 
biodiesel is also expected to have the added benefit of providing an 
expanded market for agricultural products such as corn and soybeans, 
expanding economic benefits for our nation's agricultural sector. Based 
on our analysis, there is also reason to believe that the expanded use 
of renewable fuels will provide reductions in carbon dioxide emissions 
and some air toxics emissions, such as benzene, from the transportation 
sector, while other emissions may increase.
    This action proposes regulations designed to ensure that refiners, 
blenders, and importers of gasoline will use enough renewable fuel each 
year so that this total volume requirement is met. Our proposal 
describes the standard that will apply to these parties and the 
renewable fuels that qualify for compliance. The regulations would also 
establish a trading program that would be a critical aspect of the 
overall program, allowing renewable fuels to be used where they are 
most economical while providing a flexible means for obligated parties 
to comply with the standard.

DATES: Comments: Comments must be received on or before November 12, 
2006. Under the Paperwork Reduction Act, comments on the information 
collection provisions must be received by OMB on or before October 30, 
2006.

I. Background

    This section describes the required elements of the renewable fuel 
program, also known as the Renewable Fuel Standard (RFS) program, as 
stipulated in Section 211(o) of the Clean Air Act (CAA) as amended by 
the Energy Policy Act of 2005 (the Energy Act or the Act).

A. The Role of Renewable Fuels in the Transportation Sector

    Renewable fuels have been an important part of our nation's 
transportation fuel supply for many years. Following the CAA amendments 
of 1990, the use of renewables fuels, particularly ethanol, increased 
dramatically. Several key clean fuel programs required by the CAA 
established new market opportunities for ethanol. A very successful 
mobile source control strategy, the reformulated gasoline (RFG) 
program, was implemented in 1995. This program set stringent new 
controls on the emissions performance of gasoline, which were designed 
to significantly reduce summertime ozone precursors and year round air 
toxics emissions. The RFG program also required that RFG meet an oxygen 
content standard. Several areas of the country began blending ethanol 
into gasoline to help meet this new standard, such as Chicago and St. 
Louis. Another successful clean fuel strategy required certain areas 
exceeding the national ambient air quality standard for carbon monoxide 
to also meet an oxygen content standard during the winter time to 
reduce harmful carbon

[[Page 55555]]

monoxide emissions. Many of these areas also blended ethanol during the 
winter months to help meet this new standard, such as Denver and 
Phoenix. As a result of these programs, and other factors, currently 
all areas requiring RFG or winter oxygenated fuels are blending ethanol 
at some level to support meeting the clean fuel requirements.
    Today, the role and importance of renewable fuels in the 
transportation sector continues to expand. In the past several years as 
crude oil prices have soared above the lower levels of the 1990's, the 
relative economics of renewable fuel use has improved dramatically. In 
addition, since the vast majority of crude oil produced in or imported 
into the U.S. is consumed as gasoline or diesel fuel in the U.S., 
concerns about our dependence on foreign sources of crude oil has 
renewed interest in renewable transportation fuels. The passage of the 
Energy Policy Act of 2005 demonstrated a strong commitment on the part 
of U.S. policymakers to consider additional means of supporting 
renewable fuels as a supplement to petroleum-based fuels in the 
transportation sector. The RFS program is such a program.
    The RFS program was debated by the U.S. Congress over several years 
before finally being enacted through passage of the Energy Policy Act 
of 2005. The RFS program is first and foremost designed to increase the 
use of renewable fuels in motor vehicle fuels consumed in the U.S. In 
this context, it is expected to simultaneously reduce dependence on 
foreign sources of petroleum, increase domestic sources of energy, and 
diversify our energy portfolio to help in moving beyond a petroleum-
based economy.
    The increased use of renewable fuels such as ethanol and biodiesel 
is also expected to have the added benefit of providing an expanded 
market for agricultural products such as corn and soybeans. Based on 
our analysis, there is also an expectation that the expanded use of 
renewable fuels will provide reductions in carbon dioxide emissions and 
air toxics emissions such as benzene from the transportation sector, 
while other emissions such as hydrocarbons and oxides of nitrogen may 
increase.
    The level of the renewable fuels standard set forth by Congress 
works in conjunction with other provisions that were enacted as part of 
the Energy Act. In particular, the level of the renewable fuel standard 
more than offset the possible loss in demand for renewable fuels 
occasioned by the Act's repeal of the oxygen content mandate in the 
reformulated gasoline program while allowing greater flexibility in how 
renewable fuels were blended into the nation's fuel supply. The 
renewable fuel standard additionally created a specific annual level 
for minimum renewable fuel use which increases over time, ensuring 
overall growth in the demand and opportunity for renewable fuels.
    Because renewable fuels such as ethanol and biodiesel are not new 
to the U.S. transportation sector, the expansion of their use is 
expected to follow distribution and blending practices already in 
place. For instance, the market already has the necessary production 
and distribution mechanisms in place in many areas, and the ability to 
expand these mechanisms into new markets. Recent spikes in ethanol use 
resulting first from the state MTBE bans, and now the virtual 
elimination of MTBE from the marketplace, have tested the limits of the 
ethanol distribution system. However, future growth is expected to move 
in a more orderly fashion since the use of renewable fuels will not be 
geographically constrained and, given EIA volume projections, 
investment decisions can follow market forces rather than regulatory 
mandates. In addition, the increased production volumes of ethanol and 
the expanded penetration of ethanol in new markets may create new 
opportunities for blending of E85, a blend of 85 percent ethanol and 15 
percent gasoline, in the long run. The increased availability of E85 
will mean that more flexible fueled vehicles (FFV) can use this fuel. 
Of the approximately 5 million FFVs currently in use in the U.S, most 
are currently fueled with conventional gasoline rather than E85, in 
part due to the limited availability of E85.
    Given the ever-increasing demand for petroleum-based products in 
the transportation sector, the RFS program is an important first step 
in U.S. efforts to move toward energy independence. The RFS standard 
provides the certainty that at least a minimum amount of renewable fuel 
will be used in the U.S., which in turn provides investment certainty 
for the growth in production capacity of renewable fuels. However, the 
RFS program is not the only thing impacting demand for ethanol and 
other renewable fuels. As Congress was developing the RFS program in 
the Energy Act, several large states were adopting and implementing 
bans on the use of MTBE in gasoline. As a result, refiners were forced 
to switch to ethanol to satisfy the oxygen content mandate for their 
reformulated gasoline in the U.S., causing a large, quick increase in 
demand for ethanol. Even more importantly, with the removal of the 
oxygen content mandate for RFG, refiners elected to remove essentially 
all MTBE from the gasoline supply in the U.S. during the spring of 
2006. In order to accomplish this transition quickly, while still 
maintaining gasoline volume, octane, and gasoline air toxics 
performance standards, refiners elected to blend ethanol into virtually 
all reformulated gasoline nationwide. This caused a second dramatic 
increase in demand for ethanol, which in the near term has been met by 
temporarily shifting large volumes of ethanol out of conventional 
gasoline and into the RFG areas. Perhaps the largest impact on 
renewable fuel demand, however, has been the dramatic increase in the 
cost of crude oil. In the last few years, both crude oil prices and 
crude oil price forecasts have increased dramatically. This has 
resulted in a large economic incentive for the use of ethanol and 
biodiesel. The Energy Information Administration (EIA) and others are 
currently projecting renewable fuel demand to exceed the minimum 
volumes required under the RFS program by a substantial margin. In this 
context, the statutory goal of the RFS program is to provide an 
important foundation for ongoing investment in renewable fuel 
production. However, market demand for renewable fuels is expected to 
exceed the statutory minimums. We believe we are proposing a program 
structure that could continue to operate effectively regardless of the 
level of renewable fuel use or market conditions in the energy sector.

B. Requirements in the Energy Policy Act

    Section 1501 of the Energy Policy Act provides the statutory basis 
for the RFS program. This provision was added to the CAA as Section 
211(o). It requires EPA to establish a program to ensure that the pool 
of gasoline sold in the contiguous 48 states contains specific volumes 
of renewable fuel for each calendar year starting with 2006. The 
required overall volumes for 2006 through 2012 are shown in Table I.B-1 
below.

[[Page 55556]]

 
2012....................................................             7.5
------------------------------------------------------------------------

    In order to ensure the use of the total renewable fuel volume 
specified for each year, the Agency must set a standard for each year 
representing the amount of renewable fuel that a refiner, blender, or 
importer must use, expressed as a percentage of gasoline sold or 
introduced into commerce. This yearly percentage standard is to be set 
at a level that will ensure that the total renewable fuel volumes shown 
in Table I.B-1 will be used based on gasoline volume projections 
provided by the Energy Information Administration (EIA). The standard 
for each year must be published in the Federal Register by November 30 
of the previous year. Starting with 2013, EPA is required to establish 
the applicable national volume, based on the criteria contained in the 
statute, which must require at least the same overall percentage of 
renewable fuel use as was required in 2012.
    Renewable fuels are defined in the Act primarily on the basis of 
the feedstock. In general, renewable fuels must be a motor vehicle fuel 
that is produced from plant or animal products or wastes, as opposed to 
fossil fuel sources. The Act specifically identifies several types of 
motor vehicle fuels as renewable fuels, including cellulosic biomass 
ethanol, waste-derived ethanol, biogas, biodiesel, and blending 
components derived from renewable fuel.
    The standard set annually by EPA is to be a single percentage 
applicable to refiners, blenders, and importers, as appropriate. The 
percentage standard is used by obligated parties to determine a volume 
of renewable fuel that they are responsible for ensuring is introduced 
into the domestic gasoline pool for the given year. The percentage 
standard must be adjusted such that it does not apply to multiple 
parties for the same volume of gasoline. The standard must also take 
into account the fact that small refineries are exempted from the 
program until 2011, but must take into account the use of renewable 
fuel by those small refineries.
    Under the Act, the required volumes in Table I.B-1 apply to the 
contiguous 48 states. However, Alaska and Hawaii can opt into the 
program, in which case the pool of gasoline used to calculate the 
standard, and the number of regulated parties, would change. In 
addition, other states can request a waiver of the RFS program under 
certain conditions, which would affect the national quantity of 
renewable fuel required under the program.
    The Act requires the Agency to promulgate a credit trading program 
for the RFS program whereby an obligated party may generate credits for 
over complying with their annual obligation. The obligated party can 
then use these credits or trade them for use by another obligated 
party. Thus the credit trading program allows obligated parties to 
comply in the most cost-effective manner by permitting them to 
generate, transfer, and use credits. The trading program also permits 
renewable fuels that are not blended into gasoline, such as biodiesel, 
to participate in the RFS program.
    The Agency must also determine who can generate credits and under 
what conditions, how credits may be transferred from one party to 
another, and in certain cases the appropriate value of credits for 
different types of renewable fuel. If a party is not able to generate 
or purchase sufficient credits to meet their annual obligation, they 
are allowed to carry over the deficit to the next annual compliance 
period, but must achieve full compliance in that following year.

C. Default Standard Applicable to 2006

    The Energy Act was enacted in August of 2005 and included 
provisions for a renewable fuel program that was to begin in January of 
2006. We recognized that a rulemaking implementing the full RFS 
program, including both program design and the various analyses 
necessary, would require a substantial effort involving many 
stakeholders. This process was expected to take longer than one year, 
and as a result we knew it would not be completed in time to be 
implemented by January of 2006.
    The Energy Act anticipated this possibility and specified a default 
standard applicable for just 2006. The default standard specified that 
the percentage of renewable fuel in gasoline sold or dispensed to 
consumers in the U.S. in calendar year 2006 must be 2.78 volume 
percent.\1\ The default standard would be applicable if the Agency did 
not promulgate regulations to implement the full RFS program for 2006. 
Since the full program could not be promulgated during 2006, the 
default standard of 2.78 percent applies to calendar year 2006.
    However, the provision for the default standard in the Act does not 
provide adequate specificity on how to implement the default standard. 
For instance, the Act's default standard provision does not specify the 
liable parties and the specific nature of their obligation. It also 
does not discuss compliance mechanisms, reporting requirements, or 
credit generation and use. The resulting uncertainty associated with 
the default standard would have created confusion and risked a 
problematic initial implementation of the RFS program.
---------------------------------------------------------------------------

    \1\ The default standard of 2.78 percent represented 
approximately 4.0 billion gallons of renewable fuel.
---------------------------------------------------------------------------

    As a result, the Agency published a rule on December 30, 2005 that 
interpreted and implemented the default provision, to provide certainty 
to parties involved in the production and distribution of gasoline and 
renewable fuels.\2\ In that action, the Agency clarified the default 
standard for 2006 with regulations identifying the liable parties as 
refiners, importers, and blenders. The default standard was interpreted 
as establishing a collective obligation, rather than an individual 
obligation. Under this interpretation, refiners, blenders, and 
importers are responsible as a group for meeting the default 2.78 
percent standard, and compliance with this standard is calculated over 
the pool of all gasoline sold to consumers. An individual refiner, 
blender, or importer is not responsible for meeting the 2.78 percent 
standard for the specific gasoline it produces. The regulations 
implementing the default standard for 2006 did not include any 
provisions for credit generation or trading, given the collective 
nature of the obligation. However, any shortfall in renewable fuel 
production in 2006 would be added as a deficit carryover to the 
standard for 2007. Based on information available to date, this does 
not appear to be necessary. Total ethanol production in the U.S. 
exceeded 4.0 billion gallons in 2005 by a small margin, and several 
hundred million gallons of additional ethanol production capacity has 
come online in 2006. Thus it is anticipated that the total ethanol 
production volume and ultimate use in 2006 will be more than sufficient 
to meet the default standard of 2.78 percent.
    Today's proposal outlines the full RFS program, covering all of the 
provisions required in the Act. It applies in calendar year 2007 and 
beyond, since the direct final rule described above addresses RFS 
compliance for 2006 only.
---------------------------------------------------------------------------

    \2\ 70 FR 77325 (December 30, 2005).
---------------------------------------------------------------------------

D. Development of the Proposal

    The RFS program was prescribed in section 1501 of the Act, 
including the

[[Page 55557]]

required total volumes, the timing of the obligation, the parties who 
are obligated to comply, the definition of renewable fuel, and the 
general framework for a credit program. As with many legislative 
actions, various aspects of the program require additional development 
by the Agency beyond the specifications in the Act. The credit trading 
program and related compliance mechanisms are a central aspect of the 
program, and the Agency is responsible for developing regulations to 
ensure the successful implementation of the RFS program, based on the 
framework spelled out in the statute.
    Under the RFS program the credit trading provisions will comprise a 
critical element of compliance. Many obligated parties do not have easy 
access to renewable fuels or the ability to blend them, and so will 
rely on the use of credits to comply. The RFS credit program is also 
unique in that the parties liable for meeting the standard (refiners, 
importers, and blenders of gasoline) are not generally the parties who 
make the renewable fuels or blend them into gasoline. This creates the 
need for trading mechanisms that ensure that the means to demonstrate 
compliance will be readily available for use by obligated parties.
    Given these considerations, the first step we took in developing 
the proposed program was to seek input and recommendations from the 
affected stakeholders. There were initially a wide range of thoughts 
and views on how to design the program. However, there was broad 
consensus that in the end the program should satisfy a number of 
guiding principles, including for example that the compliance and 
trading program should provide certainty to the marketplace and 
minimize cost to the consumers; that the program should preserve 
existing business practices for the production, distribution, and use 
of both conventional and renewable fuels; that the program should be 
designed to accommodate all qualifying renewable fuels; that all 
renewable volumes produced are made available to obligated parties for 
compliance; and finally that the Agency should have the ability to 
easily verify compliance to ensure that the volume obligations are in 
fact met. Over the course of several months, these guiding principles 
helped to move us toward today's proposal.

II. Overview of the Proposal

    Today's action describes our proposed requirements for the RFS 
program, as well as a preliminary assessment of the environmental and 
economic impacts of the nation's transition to greater use of renewable 
fuels. This section provides an overview of our proposal and renewable 
fuel impacts assessment. Sections III through V provide the details of 
the proposed structure of the program, while Sections VI through X 
describe our preliminary assessment of the impacts on emissions, air 
quality, fossil fuel use, and cost resulting from expanded renewable 
fuel use.

A. Impacts of Increased Reliance on Renewable Fuels

    In a typical major rulemaking, EPA would conduct a full assessment 
of the economic and environmental impacts of the program. However, as 
discussed in Section I.A., the replacement of MTBE with ethanol and the 
extremely favorable economics for renewable fuels brought on by the 
rise in crude oil prices are causing renewable fuel use to far exceed 
the RFS requirements. This makes an assessment of the program of 
limited if any utility, given that it is not currently driving real 
world impacts and future projections by the Energy Information 
Administration indicate that this favorable condition will continue. 
Consequently, it is of greater relevance and interest to assess the 
impacts of this larger increase in renewable use and the related 
changes occurring to gasoline. For this reason we have carried out an 
assessment of the economic and environmental impacts of the broader 
changes in fuel quality resulting from our nation's transition to 
greater utilization of renewable fuels, as opposed to an assessment of 
the RFS program itself.
    In summary, depending on the volume of renewable fuel assumed to be 
used in 2012 (7.5 to 9.9 billion gallons), we estimate that this 
transition to renewable fuels will reduce petroleum consumption by 2.3 
to 3.9 billion gallons or approximately 1.0 to 1.6 percent of the 
petroleum that would otherwise be used by the transportation sector. 
Carbon monoxide emissions from gasoline powered vehicles and equipment 
will be reduced by 1.3 to 3.6 percent while emissions of benzene (a 
mobile source air toxic) will be reduced by 1.7 to 6.2 percent. At the 
same time, other emissions may increase. Nationwide, we estimate 
between a 28,000 and 97,000 ton increase in VOC + NO<INF>X</INF> 
emissions. However, the effects will vary significantly by region with 
some major areas like New York City, Chicago and Los Angeles 
experiencing no increase while other areas may see an increase in VOC 
emissions from 3 to 5 percent and an increase in NO<INF>X</INF> 
emissions from 4 to 6 percent from gasoline powered vehicles and 
equipment. Furthermore, the use of renewable fuel will reduce 
CO<INF>2</INF> equivalent greenhouse gas emissions by 9 to 14 million 
tons, about 0.4 to 0.6 percent of the anticipated greenhouse gas 
emissions from the transportation sector in the United States in 2012. 
On average, we estimate the cost of this increase in renewable fuel to 
range from 0.3 cents per gallon to 1 cent per gallon of gasoline for 
the nation as a whole. We anticipate additional impacts that we intend 
to evaluate as part of the final rulemaking, including changes in 
renewable fuel feedstock market prices, decreased imports of petroleum, 
and effects on energy security.
    To carry out our analyses, we elected to use 2004 as the baseline 
from which to compare the impacts of expanded renewable use. We chose 
2004 as a baseline primarily due to the fact that all the necessary 
refinery production data, renewable production data, and fuel quality 
data was already in hand at the time we needed to begin the analysis. 
We did not use 2005 as a baseline year because 2005 may not be an 
appropriate year for comparison due to the extraordinary impacts of 
hurricanes Katrina and Rita on gasoline production and use. To assess 
the impacts of anticipated increases in renewable fuels, we elected to 
look at what they would be in 2012, the year the statutorily-mandated 
renewable fuel volumes will be fully phased in. By conducting the 
analysis in this manner, the impacts include not just the impact of 
expanded renewable fuel use by itself, but also the corresponding 
decrease in the use of MTBE, and the potential for oxygenates to be 
removed from RFG due to the absence of the RFG oxygenate mandate. Since 
these three changes are all inextricably linked and are occurring 
simultaneously in the marketplace, evaluating the impacts in this 
manner is appropriate.
    We evaluated the impacts of expanded renewable use and the 
corresponding changes to the fuel supply on fuel costs, consumption of 
fossil fuels, and some of the economic impacts on the agricultural 
sector. We also evaluated the impacts on emissions, including 
greenhouse gas emissions, and the corresponding impacts on nationwide 
and regional air quality. Our preliminary analyses are summarized in 
this section. There are a number of uncertainties associated with this 
preliminary assessment. The analyses described here will be updated for 
the final rule including additional investigation into these 
uncertainties.

[[Page 55558]]

1. Renewable Fuel Volumes Scenarios Analyzed
    As shown in Table I.B-1, the Act stipulates that the nationwide 
volumes of renewable fuel required under the RFS program must be at 
least 4.0 billion gallons in 2006 and increase to 7.5 billion gallons 
in 2012. However, we expect that the volume of renewable fuel will 
actually exceed the required volumes by a significant margin. Based on 
economic modeling, EIA projects renewable demand in 2012 of 9.6 billion 
gallons for ethanol, and 300 million gallons for biodiesel using crude 
oil prices forecast at $47 per barrel. Therefore, in assessing the 
impacts of expanded use of renewable fuels, we evaluated two 
comparative scenarios, one representing the statutorily required 
minimum, and one reflecting the higher levels projected by EIA. 
Although the actual renewable fuel volumes produced in 2012 may differ 
from both the required and projected volumes, we believe that these two 
volume scenarios together represent a reasonable range for analysis 
purposes.
    The Act also stipulates that at least 250 million gallons out of 
the total volume required in 2013 and beyond must be cellulosic biomass 
ethanol. Because we anticipate a ramp-up in production of cellulosic 
biomass ethanol products in the coming years, we have assumed that 250 
million gallons of ethanol in 2012 will come from a cellulosic biomass 
source. Also, EIA has projected in their economic modeling a biodiesel 
demand in 2012 of 300 million gallons. Thus for both the required and 
projected volume scenarios that we evaluated for 2012, we assumed these 
same production volumes for cellulosic biomass ethanol and biodiesel.
    As discussed above, we chose 2004 as our baseline. However, a 
direct comparison of the fuel quality impacts on emissions and air 
quality required that changes in overall fuel volume, fleet 
characterization, and other factors be constant. Therefore, we 
developed a reference case which represents the fuel volume, fleet 
characterization, and other factors expected in 2012. Fuel quality was 
maintained by simply growing ethanol use in equal proportion to growth 
in gasoline demand through 2012.
    A summary of the assumed renewable fuel volumes for the scenarios 
we compared is shown in Table II.A.1-1.

----------------------------------------------------------------------------------------------------------------

2. Emissions
    We evaluated the impacts of increased use of ethanol and biodiesel 
on emissions and air quality in the U.S. relative to the 2012 reference 
case. For the nation as a whole, we estimated that summertime VOC and 
NO<INF>X</INF> emissions from gasoline and diesel vehicles and 
equipment would each increase by about 0.5 percent for the 7.5 billion 
gallon scenario, and by about 1.0 percent for the 9.9 billion gallon 
scenario. This would be equivalent to between 28,000 and 97,000 tons of 
VOC + NO<INF>X</INF> nationwide. However, the effects will vary by 
region. For instance, for areas in which 10 percent ethanol blends 
already predominated in 2004, such as New York City, Chicago, and Los 
Angeles, if they continue to use ethanol at the same levels there will 
be no impact. However, for conventional gasoline areas in which no 
ethanol was used in 2004 but which are projected to transition to full 
use of ethanol in 2012, we estimated that VOC and NO<INF>X</INF> 
emissions from gasoline vehicles and equipment would increase by 3-5 
percent and 4-6 percent, respectively.
    Unlike VOC and NO<INF>X</INF>, emissions of CO and benzene from 
gasoline and diesel vehicles and equipment were estimated to decrease 
when the use of renewable fuels increased. Reductions in emissions of 
CO varied from as low as 1.3 percent to as high as 3.6 percent for the 
nation as a whole, depending on both the renewable fuel volume scenario 
and assumptions regarding the amount of ethanol used in reformulated 
versus conventional gasoline. Benzene emissions from gasoline vehicles 
and equipment were estimated to be reduced from 1.7 to 6.2 percent.
    We do not have sufficient data to predict the effect of ethanol use 
on levels of either directly emitted particulate matter (PM) or 
secondarily formed PM, but do expect a net reduction in ambient PM 
levels to result due to the secondary PM impacts as discussed in 
section VIII.C. However, data on direct PM emission impacts is 
available for biodiesel. We estimate that reductions in emissions of 
direct PM from the projected increase in the use of biodiesel to be 
about 100 tons nationwide, equivalent to less than 0.5 percent of the 
diesel PM inventory.
    The emission impact estimates described above are based on the best 
available data and models. However, it must be highlighted that most of 
the fuel effect estimates are based on very limited or old data which 
may no longer be reliable in estimating the emission impacts on 
vehicles in the 2012 fleet with advanced emission controls. \3\ As 
such, these emission estimates should be viewed as preliminary. EPA 
hopes to conduct significant new testing in order to better estimate 
the impact of fuel changes on emissions from both highway vehicles and 
nonroad equipment, including those fuel changes brought about by the 
use of renewable fuels. We hope to be able to incorporate the data from 
such additional testing into the analyses for other studies required by 
the Energy Act in 2008 and 2009, and into a subsequent rule to set the 
RFS program standard for 2013 and later.
---------------------------------------------------------------------------

    \3\ Advanced emission controls include close-coupled, high 
density catalysts and their associated electronic control systems 
for light-duty vehicles, and NO<INF>X</INF> adsorbers and PM traps 
for heavy-duty engines.
---------------------------------------------------------------------------

    We used the Ozone Response Surface Model (RSM) to estimate the 
impacts of increased use of ethanol on ozone levels for the 7.5 billion 
gallon use scenario representing the required volumes

[[Page 55559]]

under the RFS program. We did not evaluate other renewable fuel volumes 
scenarios due to the limited amount of time available for completing 
this NPRM. The ozone RSM approximates the effect of VOC and 
NO<INF>X</INF> emissions in a 37-state eastern area of the U.S. Using 
this model, we projected that the changes in VOC and NO<INF>X</INF> 
emissions could produce a very small increase in ambient ozone levels. 
On average, ozone levels increased by 0.06 ppb, which represents less 
than 0.1 percent of the standard. Even for areas expected to experience 
a significant increase in ethanol use, ozone levels increased by only 
0.1-0.2 ppb, less than 0.2 percent of the standard. These ozone impacts 
do not consider the reductions in CO emissions mentioned above, or the 
change in the types of compounds comprising VOC emissions. 
Directionally, both of these effects may mitigate these already small 
ozone increases. The ozone impacts also do not consider the impact of 
increased emissions from ethanol and biodiesel production facilities or 
any corresponding decrease in emissions from refineries.
    We investigated several other issues related to emissions and air 
quality that could affect our estimates of the impacts of increased use 
of renewable fuels. These are discussed in section VIII and in greater 
detail in the draft Regulatory Impact Analysis (DRIA). For instance, 
our current models assume that recent model year vehicles are 
insensitive to many fuel changes. However, a limited amount of new test 
data suggests that newer vehicles may be just as sensitive as older 
model year vehicles. Our sensitivity analysis suggests that if this is 
the case VOC emissions could decrease slightly while NO<INF>X</INF> 
would still increase. We also evaluated the emissions from the 
production of both ethanol and biodiesel fuel and determined that they 
will also increase with increased use of these fuels. Nationwide, 
emissions related to the production and distribution of ethanol and 
biodiesel fuel are expected to be of the same order of magnitude as the 
emission impacts related to the use of these fuels in vehicles. 
Finally, a lack of emission data and atmospheric modeling tools 
prevented us from making specific projections of the impact of 
renewable fuels on ambient PM levels. However, ethanol use may have an 
affect on ambient PM levels. Emerging science indicates that aromatic 
VOC emissions react in the atmosphere to form PM. Increased ethanol use 
is expected to cause a corresponding reduction in the aromatic content 
of gasoline, which should reduce aromatic VOC emissions and therefore 
potentially also impact atmospheric PM levels. All of these issues will 
be the subject of further study and analysis in the future.
3. Economic Impacts
    As discussed in more detail in Section X, for the final rule we 
also plan to assess a range of economic impacts that could result from 
the expanded use of renewable fuels. Due to the time required to 
complete these analyses, we only have preliminary data for some of 
these impacts available for this proposal.
    In Section VII of this preamble, we estimate the cost of producing 
the extra volumes of renewable fuel anticipated through 2012. For corn 
ethanol, we estimate the per gallon cost of ethanol to range from $1.20 
per gallon in 2012 (2004 dollars) in the case of the 7.2 billion 
gallons per year case and $1.26 per gallon in the case of the 9.6 
billion gallon case. These costs take into account the cost of the 
feedstock (corn), plant equipment and operation and the value of any 
co-products (distiller's dried grain and solubles, for example). For 
biodiesel, we estimate the per gallon cost to be between $1.89 and 
$2.11 per gallon if produced using soy bean oil, and less if using 
yellow grease or other relatively low cost or no-cost feedstocks. All 
of these fuel production costs are without accounting for tax subsidies 
for these renewable fuels.\4\ We also note that these costs represent 
the production cost of the fuel and not the market price. In recent 
years, the prices of ethanol and biodiesel have tended to track the 
prices of gasoline and diesel, in some cases even exceeding those 
prices.
---------------------------------------------------------------------------

    \4\ Tax subsidies were subtracted out of the cost estimates, but 
consumer behavior in the absence of these tax subsidies was not 
modeled.
---------------------------------------------------------------------------

    These renewable feedstocks are then used as blend fuels in gasoline 
and diesel. While biodiesel is typically just blended with petroleum 
diesel, additional efforts are sometimes necessary and/or economically 
advantageous at the refiner level when adding ethanol to gasoline. For 
example, ethanol's high octane reduces the need for other octane 
enhancements by the refiner, whereas offsetting the volatility increase 
caused by ethanol may require removal of other highly volatile 
components. Section VII examines these fuel cost impacts and concludes 
that the net cost to society in 2012 in comparison to the reference 
case of the increased use of renewable fuels and their replacement of 
MTBE, will range from an estimate of 0.3 cent to 1 cent per gallon of 
gasoline.
    This fuel cost impact does not consider other societal benefits. 
For example, the petroleum-based fuel displaced by renewable fuel, 
largely produced in the United States, should reduce our use of 
imported oil and fuel. We estimate that 95 percent of the lifecycle 
petroleum reductions resulting from the use of renewable fuel will be 
met through reductions in net petroleum imports. In Section IX of this 
preamble we estimate the value of the decrease in imported petroleum at 
about $3.5 billion in 2012 for the 7.5 billion gallon case and $5.8 
billion for the 9.6 billion gallon case, in comparison to our 2012 
reference case. Total petroleum import expenditures in 2012 are 
projected to be about $698 billion.
    The above numbers only assess those impacts of increased production 
and use of renewable fuel that we can quantify at this time. The RFS 
program attempts to spur the increased use of renewable transportation 
fuels made principally from agricultural crops produced in the U.S. As 
a result, it is important to analyze the consequences of the transition 
to greater renewable fuel use in the U.S. agricultural sector. To 
analyze the impacts on the U.S. agricultural sector, EPA has selected 
the Forest and Agricultural Sector Optimization Model (FASOM) developed 
by Professor Bruce McCarl, Texas A&M University and others over the 
past thirty years. FASOM is a dynamic, nonlinear programming model of 
the agriculture and forestry sectors of the U.S. (For this analysis, we 
will be focusing upon the agriculture portion of the model.) The 
strength of this model is its consideration of the full direct and 
indirect impacts of a shift in production of an agricultural commodity. 
For example, increased ethanol use will increase the demand for corn. 
The model assesses not only the impacts of increased demand for corn on 
acres devoted to corn production but also where the incremental corn 
will be produced, what other crops will be displaced and how corn is 
allocated among competing uses. Shifts in corn production will likely 
impact the price of corn and other crop prices. The model can also 
estimate the impacts of increased renewable fuel use on animal feed 
costs, animal production, costs to consumers and U.S. agricultural 
exports. Similarly, FASOM can estimate effects on U.S. farm employment 
and income (broken down by region, and farm sector such as corn farmers 
versus soybean producers versus the livestock industry, for example).

[[Page 55560]]

    One of the effects of increased use of renewable fuel is that it 
diversifies the energy sources used in making transportation fuel. To 
the extent that diverse sources of fuel energy reduce the dependence on 
any one source, the risks, both financial as well as strategic, of 
potential disruption in supply or spike in cost of a particular energy 
source is reduced. As part of the RFS rulemaking, EPA is estimating the 
energy security effects of reduced oil use due to the expanded use of 
renewable fuel. However, these analyses will not be available until the 
final rule.
4. Greenhouse Gases and Fossil Fuel Consumption
    There has been considerable interest in the impacts of fuel 
programs on greenhouse gases and fossil fuel consumption. Therefore, in 
this proposed rulemaking we have undertaken an analysis of the 
greenhouse gas and fossil fuel consumption impacts of a transition to 
greater renewable fuel use. This is the first analysis of its kind in a 
major rule, and as such it may guide future work in this area.
    As a result of the transition to greater renewable fuel use, some 
petroleum-based gasoline and diesel will be directly replaced by 
renewable fuels. Therefore, consumption of petroleum-based fuels will 
be lower than it would be if no renewable fuels were used in 
transportation vehicles. However, a true measure of the impact of 
greater use of renewable fuels on petroleum use, and indeed on the use 
of all fossil fuels, accounts not only for the direct use and 
combustion of the finished fuel in a vehicle or engine, but also 
includes the petroleum use associated with production and 
transportation of that fuel. For instance, fossil fuels are used in 
producing and transporting renewable feedstocks such as plants or 
animal byproducts, in converting the renewable feedstocks into 
renewable fuel, and in transporting and blending the renewable fuels 
for consumption as motor vehicle fuel. Likewise, fossil fuels are used 
in the production and transportation of petroleum and its finished 
products. In order to estimate the true impacts of increases in 
renewable fuel use on fossil fuel use, we must take these steps into 
account. Such analyses are termed lifecycle analyses.
    We compared the lifecycle impacts of renewable fuels to the 
petroleum-based gasoline and diesel fuels that they replace. This 
analysis allowed us to estimate not only the overall impacts of 
renewable fuel use on petroleum use, but also on emissions of 
greenhouse gases such as carbon dioxide from all fossil fuels. Based on 
a comparison to the 2004 base fuel, we estimated that the increased use 
of renewable fuels will reduce petroleum consumption by about 1.0 to 
1.6 percent in the transportation sector in 2012. This is equivalent to 
2.3-3.9 billion gallons of petroleum in 2012. We also estimated that 
greenhouse gases from the transportation sector will be reduced by 
about 0.4-0.6 percent, equivalent to about 9-14 million tons. These 
reductions are projected to continue to increase in the future as crude 
oil prices are expected to continue to provide the stimulus for greater 
use of renewable fuels beyond 2012. These greenhouse gas emission 
reductions are also dominated by the forecast that the majority of the 
future ethanol use will be produced from corn. If advances in 
cellulosic technology allow its use to exceed the levels assumed in our 
analysis, then even greater greenhouse gas reductions would result.\5\
---------------------------------------------------------------------------

    \5\ Cellulosic ethanol is estimated to provide a comparable 
petroleum displacement as corn derived ethanol on a per gallon 
basis, though the impacts on total energy and greenhouse gas 
emissions differ.
---------------------------------------------------------------------------

5. Potential Water Quality Impacts
    Expansion in the use of renewable fuels will also have other 
important impacts which should be the focus of further study and 
evaluation. In particular, renewable fuels such as ethanol and 
biodiesel produced from agricultural feedstocks raise important issues 
with respect to the water quality impacts resulting from the increased 
production of corn and soybeans. Due to competing demand, which 
includes livestock producers, sweetener manufacturers, and foreign 
buyers among others, it is extremely unlikely that the current corn 
crop would be devoted to ethanol production. USDA's Economic Research 
Service predicts that current demand for feed and exports are expected 
to stay constant or perhaps rise.\6\ Additional corn-based ethanol 
production would have to come from increased corn yields, increased 
acreage, and switching acreage to corn production from other crops like 
soybeans and cotton.\7\

Section IX.
---------------------------------------------------------------------------

    Changes in agriculture as a result of increased use of renewable 
fuels can have significant adverse effects upon water quality, either 
locally or on a more broad basis. This has the potential to lead to 
increased runoff and delivery to water bodies of nutrients, pesticides 
and sediments, as well as increased salinity of farmland resulting from 
increased irrigation. The increased runoff of nutrients in turn can 
cause eutrophication of small water bodies as a result of localized 
runoff or large water bodies as a result of increased regional runoff 
such as currently occurs in the creation of the hypoxic zone in the 
Gulf of Mexico, or eutrophication in the Chesapeake Bay. Some lands 
have been retired (e.g., under the Farm Bill's Conservation Reserve 
Program, or simply at the land-owner's initiative) because those lands 
are highly erosive, steep, or adjacent to water bodies. Therefore, 
farming these lands without appropriate mitigation measures would pose 
a particularly great risk to water quality and threaten to erase some 
of the gains of the last 20 years of Farm Bill and Clean Water Act 
implementation. Note that there may be similar environmental 
implications in other countries depending on the extent that either 
imports of renewable fuels or exports of agricultural commodities such 
as corn are affected.
    We have not conducted an analysis for this proposal of the impacts 
on water quality that might result from the increased use of renewable 
fuels. However, this impact could present important public policy 
issues as renewable use expands, with examination required of both the 
possible benefits and detriments.

B. Program Structure

    The RFS program proposed today requires refiners, importers, and 
blenders (other than oxygenate blenders) to show that a required volume 
of renewable fuel is used. The required volume is determined by 
multiplying their annual gasoline production by a percentage standard 
specified by EPA. Compliance is demonstrated through the acquisition of 
unique Renewable Identification Numbers (RINs) assigned by the producer 
to every batch of renewable fuel produced. The RIN shows that a certain 
volume of renewable fuel was produced. Each year, the refiners, 
blenders and importers obligated to meet the renewable volume 
requirement (referred to as ``obligated parties'') must acquire 
sufficient RINs to demonstrate compliance with their volume obligation. 
RINs can be traded in the same manner as the credits envisioned in the 
Act. A system of recordkeeping and electronic reporting for all parties 
that have RINs ensures the integrity of the RIN pool. This RIN-based 
system would both meet the requirements of the Act and provide several 
other important advantages:

[[Page 55561]]

    <bullet> Renewable fuel production volumes can be easily verified.
    <bullet> RIN trading can occur in real time as soon as the 
renewable fuel is produced rather than waiting to the end of the year 
when an obligated party would determine if it had exceeded the 
standard.
    <bullet> Renewable fuel can continue to be produced, distributed, 
and blended in those markets where it is most economical to do so.
    <bullet> Instances of double-counting of renewable fuel claimed for 
compliance purposes can be identified based on electronically reported 
data.
    Our proposed RIN-based trading program will be an essential 
component of the RFS program, ensuring that every obligated party can 
comply with the standard while providing the flexibility for each 
obligated party to use renewable fuel in the most economical ways 
possible.
1. What Is the RFS Program Standard?
    EPA is required to convert the aggregate national volumes of 
renewable fuel specified in the Act into corresponding renewable fuel 
standards expressed as a percent of gasoline production. The renewable 
volume obligation that would apply to an obligated party would then be 
determined based on this percentage and the total gasoline production 
or import volume in a calendar year, January 1 through December 31. EPA 
will publish the percentage standard in the Federal Register each 
November for the following year based on the most recent EIA gasoline 
demand projections. However, since this rulemaking will not be 
finalized prior to November, 2006, we are proposing in this notice that 
the standard for 2007 be 3.71 percent. Section III.A describes the 
calculation of the standard.
2. Who Must Meet the Standard?
    Under our proposal, any party that produces gasoline for 
consumption in the U.S., including refiners, importers, and blenders 
(other than oxygenate blenders), would be subject to a renewable volume 
obligation that is based on the renewable fuel standard. These 
obligated parties would determine the level of their obligation by 
multiplying the percentage standard by their annual gasoline production 
volume. The result would be the renewable fuel volume which each party 
must ensure is blended into gasoline consumed in the U.S., with credit 
for certain other renewable fuels that are not blended into gasoline. 
EPA will publish the percentage standard for a year by November of the 
preceding year.
    For 2007, we are proposing that the renewable fuel volume 
obligation be etermined by multiplying the percentage standard by the 
volume of gasoline produced or imported prospectively from the 
effective date of the final rule until December 31, 2007. As discussed 
in Section III.A.3, we considered and are seeking comment on several 
other approaches for compliance in 2007, but believe this approach is 
most appropriate given the circumstances. We are also confident that 
the total volume of renewable fuel used in 2007 will still exceed the 
volume specified in the Act.
    In determining their annual gasoline production volume, obligated 
parties would include all of the finished gasoline which they produced 
or imported for use in the contiguous 48 states, and would also include 
renewable blendstock for oxygenate blending (RBOB), and conventional 
blendstock for oxygenate blending (CBOB). Blenders would count as their 
gasoline production only the volumes of blendstocks added to finished 
or unfinished gasoline. Renewable fuels blended into gasoline by any 
party would not be counted as gasoline for the purposes of calculating 
the annual gasoline production volume.
    Small refiners and small refineries would be exempt from meeting 
the renewable fuel requirements through 2010. All gasoline producers 
located in Alaska, Hawaii, and noncontiguous U.S. territories would be 
exempt indefinitely. However, if Alaska, Hawaii or a noncontiguous 
territory opted into the RFS program, all of the refiners (except for 
small refiners and refineries), importers, and blenders located in the 
state would be subject tothe renewable fuel standard.
    Section III.A provides more details on the standard that must be 
met, while Section III.C describes the parties that are obligated to 
meet the standard.
3. What Qualifies as a Renewable Fuel?
    We have designed the proposal flexibly to cover the range of 
renewable fuels produced today as well as any that might be produced in 
the future, so long as they meet the Act's definition of renewable fuel 
and have been registered and approved for use in motor vehicles. In 
this manner, we believe that the proposed program will provide the 
greatest possible encouragement for the development, production, and 
use of renewable fuels to reduce our dependence on petroleum. In 
general, renewable fuels must be produced from plant or animal products 
or wastes, as opposed to fossil fuel sources. Valid renewable fuels 
would include ethanol made from starch seeds, sugar, or cellulosic 
materials, biodiesel (mono-alkyl esters), non-ester renewable diesel, 
and a variety of other products. Both renewable fuels blended into 
conventional gasoline or diesel and those used in their neat 
(unblended) form as motor vehicle fuel would qualify. Section III.B 
provides more details on the renewable fuels that would be allowed to 
be used for compliance with the standard under our proposal.
4. Equivalence Values of Different Renewable Fuels
    One question that EPA faced in developing the program was what 
value to place on different renewable fuels and on what basis should 
that value be determined. The Act specifies that each gallon of 
cellulosic ethanol be treated as if it were 2.5 gallons of renewable 
fuel, but does not specify the values for other renewable fuels. As 
discussed in Section III.B.4., we considered and are seeking comment on 
a range of options including straight volume, energy content, and life 
cycle energy or greenhouse gas emissions. However, we are proposing 
that the ``Equivalence Values'' for the different renewable fuels be 
based on their energy content in comparison to the energy content of 
ethanol, and adjusted as necessary for their renewable content. The 
result is an Equivalence Value for corn ethanol of 1.0, for biobutanol 
of 1.3, for biodiesel (mono alkyl ester) of 1.5, for non-ester 
renewable diesel of 1.7, and for cellulosic ethanol of 2.5. The 
proposed methodology can be used to determine the appropriate 
Equivalence Value for any other potential renewable fuel as well.
5. How Will Compliance Be Determined?
    Under our proposed program, every gallon of renewable fuel produced 
or imported into the U.S. would be assigned a unique renewable 
identification number (RIN). A block of RINs could be assigned to any 
batch of renewable fuel that is valid for compliance purposes under the 
RFS program. These RINs would be placed on product transfer documents 
(PTD) as a batch of renewable fuel is transferred through the 
distribution system. Once the renewable fuel is obtained by an 
obligated party or actually blended into a motor vehicle fuel, the RIN 
could be separated from the batch of renewable fuel to which it had 
been assigned, and then either used for compliance purposes or traded. 
For excess RINs

[[Page 55562]]

resulting from the production of renewable fuels with Equivalence 
Values greater than 1.0, the producer of the renewable fuel could 
retain them for marketing separately (they need not be assigned to a 
batch of renewable fuel and placed on PTDs).
    RINs would represent proof of production which is then taken as 
proof of consumption as well, since all renewable fuel produced or 
imported will be either consumed as fuel or exported. For instance, 
ethanol produced for use as motor vehicle fuel is denatured 
specifically so that it can only be used as fuel. Similarly, biodiesel 
is produced only for use as fuel and has no other potential uses. An 
obligated party would demonstrate compliance with the renewable fuel 
standard by accumulating sufficient RINs to cover their individual 
renewable fuel volume obligation. It would not matter whether the 
obligated party used the renewable fuel themselves. A party's 
obligation would be to ensure that a certain amount of renewable fuel 
was used, whether by themselves or by someone else, and the RIN would 
be evidence that this occurred for a certain volume of renewable fuel. 
Exporters of renewable fuel would also be required to retire RINs in 
sufficient quantities to cover the volume of renewable fuel exported. 
RINs claimed for compliance purposes would thus represent renewable 
fuel actually consumed as motor vehicle fuel in the U.S.
    RINs would be valid for compliance purposes for the calendar year 
in which they were generated, or the following calendar year. This 
approach to RIN life would be consistent with the Act's prescription 
that credits be valid for compliance purposes for 12 months as of the 
date of generation. An obligated party could either use RINs to 
demonstrate compliance, or could transfer RINs to any other party. If 
an obligated party was not able to accumulate sufficient RINs for 
compliance in a given year, it could carry a deficit over to the next 
year so long as the full deficit and obligation were covered in the 
next year.
    In order to ensure that previous year RINs are not used 
preferentially for compliance purposes in a manner that would 
effectively circumvent the limitation that RINs be valid for only 12 
months after the year generated, we are proposing to place a cap on the 
use of RINs generated the previous year when demonstrating compliance 
with the renewable volume obligation for the current year. The cap 
would mean that no more than 20% of the current year obligation could 
be satisfied using RINs from the previous year. In this manner there is 
no ability for excess renewable fuel use in successive years to cause 
an accumulation of RINs from excess compliance in prior years to 
significantly depress renewable fuel demand in any future year. In 
keeping with the Act, excess RINs not used would expire.
    Section III.D provides more details on how obligated parties would 
use RINs for compliance purposes.
6. How Would the Trading Program Work?
    Renewable fuel producers and importers would be required to 
generate RINs when they produce or import a batch of renewable fuel. 
They would then be required to transfer those RINs along with the 
renewable fuel batches that they represent whenever they transfer the 
batch to another person. Likewise any other party that takes ownership 
or custody of the batch would be required to transfer the RIN with the 
batch. The RIN could be separated from the batch only by obligated 
parties (at the point when they take ownership of the batch) or a party 
that converts the renewable fuel into motor vehicle fuel (such as 
through blending with conventional gasoline or diesel).
    Once a RIN is separated from the batch of renewable fuel that it 
represents, it can be used for compliance purposes, banked, or traded 
to another party. Separated RINs could be transferred to any party any 
number of times. Recordkeeping and reporting requirements would apply 
to any party that holds RINs, whether through the ownership or custody 
of a batch of renewable fuel or through the transfer of separated RINs.
    Thus obligated parties could acquire RINs directly through the 
purchase of renewable fuel with assigned RINs, or through the open 
market for RINs that would be allowed under this proposal. Section 
III.E provides more details on how our proposed RIN trading program 
would work.
7. How Would the Program be Enforced?
    As in all EPA fuel regulations, there would be a system of 
registration, recordkeeping, and reporting requirements for obligated 
parties, renewable producers (RIN generators), as well as any parties 
that procure or trade RINs either as part of their renewable purchases 
or separately. In most cases, the recordkeeping requirements are not 
expected to be significantly different from what these parties might be 
doing already as a part of normal business practices. The lynch pin to 
the compliance program, however, is the unique RIN number itself 
coupled with an electronic reporting system where RIN generation, RIN 
use, and RIN transactions would be reported and verified. Thus, EPA, as 
well as industry could have confidence that invalid RINs are not 
generated and that there is no double counting.

C. Voluntary Labeling Program

    EPA is considering whether voluntary program options to encourage 
adoption and use of practices that minimize environmental concerns 
which may arise with the production of renewable fuels are appropriate. 
Renewable fuels present a number of environmental advantages as 
explained elsewhere in the rulemaking package. However, to assure 
maximum advantage we also need to acknowledge the potential adverse 
environmental impacts that could arise from the production of renewable 
fuel and invite consideration of ways of offsetting these potential 
adverse impacts.
    While in other areas of this document we focus on general impacts 
on air emissions, we also recognize that individual farming and fuel 
production operations can contribute to air and water pollution if 
appropriate practices and/or controls are not adopted. Increased 
production of renewable fuel may result in more intensive use of crop 
lands and perhaps the addition of crop land acres to meet the expanding 
need for renewable feed stocks. Such trends could have an adverse 
impact on, for example, local water quality. Similarly in the case of 
fuel production facilities, a range of design and operation options 
could result in varying levels of energy use and air and water 
pollution.
    EPA is considering what voluntary program(s) can be put into place 
that would encourage farming and fuel production practices to minimize 
concerns that expanded production of renewable fuel in the United 
States is likely to result in adverse environmental impacts such as 
those identified above.
    One option could be a voluntary labeling program which would make 
use of the RIN program proposed in this rulemaking. Under this concept, 
fuel producers which use best practices would have the option of adding 
a ``G'' (for ``green'') to the end of the RIN of a fuel to indicate 
that a gallon of renewable fuel was produced with the combination of 
best farming practices, and environmentally friendly production methods 
and facilities. The details of such a concept, including the points 
noted below, would need to be developed before it could be fully 
considered for adoption.

[[Page 55563]]

    At this time, we are requesting comments on voluntary programs that 
would recognize the efforts of farmers and renewable fuel producers 
that undertake the most environmentally sound practices and encourage 
others to adopt similar practices. In particular we are interested in 
comments on options for designs of potential voluntary programs 
including what criteria should be used to establish environmentally 
sound practices, how to verify that these environmental practices are 
indeed used in the production of renewable fuel, how this information 
could be used to promote expanded use of good practices, how the 
program could be most efficiently and effectively administered whether 
by EPA, some other Federal agencies, or perhaps a third-party, and 
finally how to assess effectiveness of such a voluntary program.

III. Complying With the Renewable Fuel Standard

    According to the Energy Act, the RFS program places obligations on 
individual parties such that the renewable fuel volumes shown in Table 
I.B-1 are actually used as motor vehicle fuel in the U.S. each year. To 
accomplish this, the Agency must calculate and publish a standard by 
November 30 of each year which is applicable to every obligated party. 
On the basis of this standard each obligated party determines the 
volume of renewable fuel that it must ensure is consumed as motor 
vehicle fuel. In addition to setting the standard, we must clarify who 
the obligated parties are and what volumes of gasoline are subject to 
the standard. Obligated parties must also know which renewable fuels 
are valid for RFS compliance purposes, and how much credit each type of 
renewable fuel will receive. This section discusses how the annual 
standard is determined and which parties and volumes of gasoline would 
be subject to the proposed requirements.
    Because renewable fuels are not produced or distributed evenly 
around the country, some obligated parties will have easier access to 
renewable fuels than others. As a result, compliance with the RFS 
program requirements will depend heavily on a credit trading program. 
This section also describes all the elements of our proposed credit 
trading program.

A. What Is the Standard That Must Be Met?

1. How Is the Percentage Standard Calculated?
    Table I.B-1 shows the required total volume of renewable fuel 
specified in the Act for 2007 through 2012. The renewable fuel standard 
is based primarily on (1) the 48-state gasoline consumption volumes 
projected by EIA as the Act exempts Hawaii and Alaska, subject to their 
right to opt-in, as discussed in Section III.C.4, and (2) the volume of 
renewable fuels required by the Act for the coming year. The renewable 
fuel standard will be expressed as a volume percentage of gasoline sold 
or introduced into commerce in the U.S., and would be used by each 
refiner, blender or importer to determine their renewable volume 
obligation. The applicable percentage is set so that if each regulated 
party meets the renewable volume obligation based on this percentage 
then the total amount of renewable fuel used is expected to meet the 
total renewable fuel volume specified in Table I.B-1.
    In determining the applicable percentage for a calendar year, the 
Act requires EPA to adjust the standard to prevent the imposition of 
redundant obligations on any person and to account for the use of 
renewable fuel during the previous calendar year by exempt small 
refineries, defined as refineries that process less than 75,000 bpd of 
crude oil. As a result, in order to be assured that the percentage 
standard will in fact result in the volumes shown in Table I.B-1, 
several adjustments to what is otherwise a simple calculation must be 
made.
    As stated, the renewable fuel standard for a given year is 
basically the ratio of the amount of renewable fuel specified in the 
Act for that year to the projected 48-state non-renewable gasoline 
volume for that year. While the required amount of total renewable fuel 
for a given year is provided by the Act, EPA is required to use an EIA 
estimate of the amount of gasoline that will be sold or introduced into 
commerce for that year. The level of the percentage standard would be 
further reduced if Alaska, Hawaii, or a U.S. territory chose to 
participate in the RFS program, as gasoline produced in or imported 
into those states or territories would then be subject to the standard. 
Should any of these states or territories choose to opt into the RFS 
program, the projected gasoline volume would increase above that 
consumed in the 48 contiguous states. EIA has indicated that the best 
estimation of the coming year's gasoline consumption is found in Table 
5a (U.S. Petroleum Supply and Demand: Base Case) of the October issue 
of the monthly EIA publication Short-Term Energy Outlook which 
publishes quarterly energy projections. Since the October 2006 document 
is not currently available for the purpose of proposing the 2007 
standard and projecting the 2008 and later standards, we have used the 
gasoline volume projections in EIA's 2006 Annual Energy Outlook (AEO), 
Table A2 ``Energy Consumption by Sector and Source.'' We intend to use 
the October 2006 Short-Term Energy Outlook values for the final rule.
    However, these gasoline volumes include renewable fuel use, which 
in the coming years is expected to be mostly ethanol. As discussed 
below in Section III.C.1, the renewable fuel obligation will not apply 
to renewable blenders. Thus, the gasoline volume used to determine the 
standard must be the non-renewable portion of the gasoline pool, in 
order to achieve the volumes of renewables specified in the Act. In 
order to get a total non-renewable gasoline volume, the renewable fuel 
volume must be subtracted from the total gasoline volume. EIA has 
indicated that the best estimation of the coming year's renewable fuel 
consumption is found in Table 11 (U.S. Renewable Energy Use by Sector: 
Base Case) of the October issue of the monthly EIA publication Short-
Term Energy Outlook. For the purpose of proposing the 2007 standard and 
projecting the 2008 and later standards, we have used the renewable 
(ethanol) volume projections in EIA's 2006 Annual Energy Outlook (AEO), 
Table 17 ``Renewable Energy Consumption by Sector and Source.'' As for 
the gasoline projections discussed above, we intend to use the October 
2006 renewable fuel values for the final rule.
    The Act exempts small refineries \8\ from the RFS requirements 
until the 2011 compliance period. As discussed in Section III.C.3.a, 
EPA is proposing to also exempt small refiners \9\ from the RFS 
requirements until 2011, and to treat small refiner gasoline volumes 
the same as small refinery gasoline volumes. Since small refineries and 
small refiners would be exempt from the program until 2011, EPA is 
proposing that their gasoline volumes be excluded from the overall non-
renewable gasoline

[[Page 55564]]

volume used to determine the applicable percentage. EPA believes this 
is appropriate because the percentage standard should be based only on 
the gasoline subject to the renewable volume obligation. This would 
only occur though the 2010 compliance period when the exemption ends. 
Calculation of the standard for calendar year 2011 and beyond would 
include small refinery and small refiner volumes.
---------------------------------------------------------------------------

    \8\ Under the Act, small refineries are those with 75,000 bbls/
day or less average aggregate daily crude oil throughput.
    \9\ Small refiners are those entities who produced gasoline from 
crude oil in 2004, and who meet the crude processing capability (no 
more than 155,000 barrels per calendar day, bpcd) and employee (no 
more than 1500 people) criteria as specified in previus EPA fuel 
regulations.
---------------------------------------------------------------------------

    As discussed above, calculation of the standard requires 
projections of gasoline use for the upcoming compliance period. EIA 
does not project small refinery or small refiner gasoline volumes, so 
other methods of estimating these values are necessary. EPA receives 
gasoline production data as a part of its fuel programs' reporting 
requirements that could be used for this purpose. However, since we do 
not receive the data until late February, the most recent complete 
annual data set available would be from two years earlier. Given this, 
the fact that this adjustment is only needed for 4 years, and because 
the total small refinery and small refiner gasoline production volume 
is expected to be fairly constant compared to total U.S. gasoline 
production during this period, we are proposing to estimate small 
refinery and small refiner gasoline volumes using a constant percentage 
of national consumption. This percentage would be based on the most 
recent small refinery and small refiner gasoline data available in time 
for the final rule. Using information from gasoline batch reports 
submitted to EPA, EIA data and input from the California Air Resources 
Board regarding California small refiners, we have estimated this 
percentage to be 13.5%.\10\ EPA requests comments on this method of 
estimating small refinery and small refiner gasoline volumes.

    \10\ ``Calculation of the Small Refiner/Small Refinery Fraction 
for the Renewable Fuel Program,'' memo to the docket from Christine 
Brunner, ASD, OTAQ, EPA, September 2006.
---------------------------------------------------------------------------

    The Act requires that the small refinery adjustment also account 
for renewable fuels used during the prior year by small refineries that 
are exempt and do not participate in the RFS program. Accounting for 
this volume of renewable fuel would reduce the total volume of 
renewable fuel use required, and thus directionally would reduce the 
percentage standard. However, there would be no available data on which 
to base such an adjustment. Furthermore, EPA believes that the amount 
of renewable fuel that would qualify (i.e., that was used by exempt 
small refineries and small refiners but not used as part of the RFS 
program) would be very small. In light of the total volume of renewable 
fuel required and the precision in which the statute specifies this 
total volume, the very small volume at issue here would not change the 
resulting percentage. Under the proposal, small refineries and small 
refiners are merely treated as any other renewable blender until 2011. 
Consequently, whatever renewables they blend will be reflected as RINs 
available in the market, and thus should not be accounted for in the 
equation used to determine the standard. Therefore, EPA is proposing to 
assume this value to be zero.
    We are proposing that the amount of renewable fuel used in Alaska, 
Hawaii, or U.S. territories would not affect the amount of renewable 
fuel required nationwide. We believe this approach is appropriate 
because the Act requires that the renewable fuel be consumed in the 
contiguous 48 states unless Alaska, Hawaii, or a U.S. territory opt-in. 
Additionally, renewable fuel produced in Alaska, Hawaii, and U.S. 
territories is unlikely to be transported to the contiguous 48 states, 
and vice versa. Thus, including their renewable fuel volumes in the 
calculation of the standard would not serve the purpose intended by the 
Act of ensuring that the statutorily required renewable fuel volumes 
are consumed in the 48 contiguous States.
    A final issue that could affect the calculated value of the 
standard is any deficit carryover from 2006. Any deficit carryover from 
2006 would increase the standard only for 2007. Since renewable fuel 
use in 2006 is expected to exceed the 2.78 percent default standard, we 
are proposing that no deficit be carried over to 2007. Beginning with 
the 2007 compliance period, when annual individual party compliance 
replaces collective compliance, any deficit is calculated for an 
individual party and is included in the party's Renewable Volume 
Obligation (RVO) determination, as discussed in Section III.A.4.
    In summary, in order to get the total projected non-renewable 
gasoline volumes from which to calculate the standard, EPA is proposing 
to use EIA projections of nationwide and state gasoline consumption, 
and small refinery and small refiner volumes estimated as a constant 
percentage of national gasoline volumes.
    Based on the discussion above, the formula which we are proposing 
to be used for calculating the percentage standard is shown below:
[GRAPHIC] [TIFF OMITTED] TP22SE06.000

Where:

RFStd<INF>i</INF> = Renewable Fuel standard in year i, in percent
RFV<INF>i</INF> = Nationwide annual volume of renewable fuels 
required by section 211(o)(2)(B) of the Act for year i, in gallons
G<INF>i</INF> = Amount of gasoline projected to be used in the 48 
contiguous states, in year i, in gallons
R<INF>i</INF> = Amount of renewable fuel blended into gasoline that 
is projected to be consumed in the 48 contiguous states, in year i, 
in gallons
GS<INF>i</INF> = Amount of gasoline projected to be used in Alaska, 
Hawaii, or a U.S. territory in year i if the state or territory 
opts-in, in gallons
RS<INF>i</INF> = Amount of renewable fuel blended into gasoline that 
is projected to be consumed in Alaska, Hawaii, or a U.S. territory 
in year i if the state or territory opts-in, in gallons
GE<INF>i</INF> = Amount of gasoline projected to be produced by 
exempt small refineries and small refiners in year i, in gallons 
(through 2010 only)
Cell<INF>i</INF> = Beginning in 2013, the amount of renewable fuel 
that is required to come from cellulosic sources, in year i, in 
gallons (250,000,000 gallons minimum)

    As described in III.B.4.b, we are not proposing regulations that 
would specify the criteria under which a state could petition the EPA 
for a waiver of the RFS requirements, nor the ramifications of Agency 
approval of such a waiver in terms of the level or applicability of the 
standard. As a result, the proposed formula for the standard shown 
above does not include any components to account for Agency approval of 
a state petition for a waiver of the RFS requirements.
    EPA is proposing the following formula for calculating the 
cellulosic

[[Page 55565]]

standard that is required beginning in 2013:
[GRAPHIC] [TIFF OMITTED] TP22SE06.001

    Where, except for RFCell<INF>i</INF>, the variable descriptions 
are as discussed above. The definition of RFCell<INF>i</INF> is 
proposed as:

RFCell<INF>i</INF> = Renewable Fuel Cellulosic Standard in year i, 
in percent

    EPA requests comments on the components of both of the proposed 
formulas, and on how the values for the components should be obtained.
2. What Are the Applicable Standards?
    EPA will set the percentage standard for each upcoming year based 
on the most recent EIA projections, and using the other sources of 
information as noted above. EPA will publish the standard in the 
Federal Register by November 30 of the preceding year. We are proposing 
the standard for 2007 and estimating the standard for later years based 
on current information using the formulas discussed above. The 
standards would be used to determine the renewable volume obligation 
based on an obligated party's total gasoline production or import 
volume in a calendar year, January 1 through December 31. The 
percentage standards do not apply on a per gallon basis. An obligated 
party will calculate its Renewable Volume Obligation (discussed in 
Section III.A.4) using the annual standard.
    For illustrative purposes, we have estimated the standards for 2007 
and later based on current information using the formulas discussed 
above.\11\ These values are listed below in Table III.A.2-1. The values 
of the variable RFV are the required renewable fuel volumes specified 
in the Act (and shown in Table I.B-1). The projected gasoline and 
renewable fuels volumes were determined from EIA's energy projections. 
Variables related to state or territory opt-ins were set to zero since 
we do not have any information related to their participation at this 
time. Small refinery and small refiner gasoline volumes were calculated 
based on our proposed method of assuming a constant percentage relative 
to projected nationwide gasoline. As mentioned earlier, we estimate the 
small refinery and small refiner fraction to be 13.5%. The exemption 
for small refineries and small refiners ends at the end of the 2010 
compliance period. The deficit for 2006 (applicable to the 2007 
standard) was assumed to be zero.

------------------------------------------------------------------------

    For calendar year 2013 and thereafter, the applicable volumes are 
to be determined in accordance with separate statutory provisions that 
include EPA coordination with the Departments of Agriculture and 
Energy, and a review of the program during calendar years 2006 through 
2012. The Act specifies that this review consider the impact of the use 
of renewable fuels on the environment, air quality, energy security, 
job creation, and rural economic development, and the expected annual 
rate of future production of renewable fuels, including cellulosic 
ethanol. We intend to conduct another rulemaking as we approach the 
2013 timeframe that would include our review of these factors. This 
rulemaking would present our conclusions regarding the appropriate 
applicable volume of renewable fuel for use in calculating the 
renewable fuel standard for 2013 and beyond. However, at a minimum we 
expect that the sum of the cellulosic and non-cellulosic standards for 
2013 will be no lower than the 2012 standard. Until such time as we 
conduct that rulemaking, the program proposed by this rule would 
continue to apply after 2012.
    Prior to 2013, the Act specifies that cellulosic biomass ethanol or 
waste derived ethanol will be considered equivalent to 2.5 gallons of 
renewable fuel when determining compliance with the renewable volume 
obligation. As discussed in Section III.D below, a batch's RIN would 
indicate whether it was cellulosic or non-cellulosic ethanol. Beginning 
in 2013, the 2.5 to 1 ratio no longer applies for cellulosic biomass 
ethanol. In its place, the Act requires that the applicable volume of 
required renewable fuel specified in Table I.B-1 include a minimum of 
250 million gallons that are derived from cellulosic biomass. As shown 
in Table III.A.2-1 above, we have estimated this value (250 million 
gallons) as a percent of an obligated party's production for 2013. 
Thus, an obligated party would be subject to two standards in 2013 and 
beyond, a non-cellulosic standard and a cellulosic standard.
3. Compliance in 2007
    The Energy Act requires that EPA promulgate regulations to 
implement the RFS program, and if EPA did not issue such regulations 
then a default standard for renewable fuel use would apply in 2006. As 
described in Section I.C, we promulgated a direct final rule to 
interpret and implement the application of the statutory default 
standard of 2.78 percent in calendar year 2006. However, the Act 
provides no default standard for any other year. Instead, the 
regulations we promulgate are required to address renewable fuel usage, 
including calendar year 2007. The program we are proposing today will 
therefore apply in 2007. While we plan to promulgate the final rule as 
soon after today's proposal as possible, it will likely not be 
effective by January 1, 2007. Therefore, our proposal must address how, 
and for what time periods, the applicable standard and other program 
requirements will apply to regulated parties for gasoline produced 
during 2007.
    We have identified several options for 2007 compliance. One option 
would be to extend the collective compliance approach used for 2006 to 
2007. Although the Act contains no default

[[Page 55566]]

standard applicable to 2007, under this approach we would apply the 
renewable fuel standard that we calculate for 2007 to obligated parties 
on a collective basis rather than on an individual basis. Under this 
approach, no individual facility or company would be liable for meeting 
the applicable standard. At the end of 2007 we would determine if the 
industry as a whole had met the standard on average, and any deficit 
would be carried over into 2008. This approach would be essentially 
equivalent to deferring the start of the program to 2008, but with the 
addition of an industry-wide deficit carryover provision. Current 
projections from the Energy Information Administration (EIA) on the 
volume of renewable fuel expected to be produced in 2007 indicate that 
an industry-wide deficit carryover would most likely be unnecessary 
under this collective compliance approach.
    However, given the requirements of the Act, we do not believe that 
a collective compliance approach is appropriate for 2007. The Energy 
Act requires us to promulgate regulations that provide for the 
generation of credits by any person who overcomplies with their 
obligation. It also stipulates that a person who generates credits must 
be permitted to use them for compliance purposes, or to transfer them 
to another party. These credit provisions have meaning only in the 
context of an individual obligation to meet the applicable standard. 
Delaying a credit program until 2008 would mean the credit provisions 
have no meaning at all for 2007.
    A variation of the collective compliance approach would add a 
credit carryover provision in which any excess renewable fuel produced 
on an industry-wide basis in 2007 would be subtracted from the required 
volume in the calculation of the applicable 2008 standard. However, 
under a collective compliance approach, such a credit carryover 
provision would not meet the statutory requirement since no individual 
companies could generate, bank, or trade credits. Therefore we do not 
believe that a collective compliance approach is appropriate.
    Another option for 2007 compliance would be for obligated parties 
to calculate their renewable fuel obligation based on all gasoline 
volumes produced at any time during the calendar year, regardless of 
when in 2007 the final rule is published or becomes effective (i.e., 
the calculation of the renewable volume obligation looks back 
retroactively to the beginning of the year for gasoline production). 
Compliance would be determined based on a whole calendar year's 
production of gasoline, and the compliance determination would not be 
required until calendar year 2007 was over, after the final rule was 
published. Obligated parties would know the proposed standard based on 
today's action, and all regulated parties would likewise know the 
proposed provisions for recordkeeping, RIN generation and assignment, 
etc. On this basis they could begin the process of generating RINs and 
tracking batches of renewable fuel prior to the publication of the 
final rule. However, it might not be appropriate to apply the standard 
to all gasoline produced in 2007 unless the regulatory provisions in 
today's proposal are very similar to those in the final rule. 
Otherwise, obligated parties and renewable fuel producers would not 
have adequate lead-time.
    For this approach to be effective, renewable producers would have 
to begin placing RINs on their PTDs at the start of the year 2007 even 
though the regulations are not yet final. If they do not, then there 
could be a shortage of RINs available for obligated parties to use for 
compliance by the end of the year. Since there is no guarantee that 
renewable fuel producers would generate RINs appropriate prior to 
adoption of the regulations, another option would be for the Agency to 
finalize just those RIN-related provisions prior to the end of 2006 
that are critical to measuring and tracking batches of renewable fuel 
and the assignment of RINs to those batches. However, in practice this 
approach would be little different than finalizing the full rulemaking. 
As a result we do not believe that this would be a viable option given 
the time available.
    Finally, given the challenges and shortcomings inherent in the 
other options, we could simply apply the renewable fuel standard to 
only those volumes of gasoline produced after the effective date of the 
final rule. Essentially the renewable volume obligation for 2007 would 
be based on only those volumes of gasoline produced or imported by an 
obligated party prospectively from the effective date of the rulemaking 
forward, and renewable producers would not have to begin generating 
RINs and maintaining the necessary records until this same date. As a 
result, such an approach would be relatively straightforward to 
implement, provide the industry with the certainty they need to comply, 
and give them time to put in place their compliance plans and actions. 
It also would be unlikely to have any negative impacts on renewable 
fuel use given the expectations that total volumes in 2007 will exceed 
the national volume required for 2007. This is the approach we are 
proposing today.
    This ``prospective'' approach would not formally apply the standard 
to all of the gasoline produced in the 2007 calendar year. As a result, 
it would not formally ensure that the total volume of renewable fuel 
required to be used in 2007 would actually be used. However, given the 
present circumstances, we believe this is an appropriate way to 
implement the Act's provisions. We are confident that the combined 
effect of the proposed regulatory requirements for 2007 and the 
expected market demand for renewable fuels will lead to greater 
renewable fuel use in 2007 than is called for under the Act. 
Furthermore, refiners and importers are not required to meet any 
requirements under the Act until EPA adopts the regulations, and EPA is 
authorized to consider appropriate lead time in establishing the 
regulatory requirements.\12\ Under this option we believe there would 
be reasonable lead-time for regulated parties to meet their 2007 
compliance obligations.
---------------------------------------------------------------------------

    \12\ The statutory default standard for 2006 is the one 
exception to this, since it directly establishes a renewable fuel 
obligation applicable to refiners and importers in the event that 
EPA does promulgate regulations.
---------------------------------------------------------------------------

    While we are proposing to apply the renewable fuel standard for 
2007 prospectively only from the effective date of the final rule, we 
nevertheless request comment on all these options for addressing 
compliance in calendar year 2007.
4. Renewable Volume Obligations
    In order for an obligated party to demonstrate compliance, the 
percentage standards described in Section III.A.2 which are applicable 
to all obligated parties must be converted into the volume of renewable 
fuel each obligated party is required to satisfy. This volume of 
renewable fuel is the volume for which the obligated party is 
responsible under the RFS program, and is referred to here as its 
Renewable Volume Obligation (RVO).
    The calculation of the RVO requires that the standard shown in 
Table III.A.2-1 for a particular compliance year be multiplied by the 
gasoline volume produced by an obligated party in that year. To the 
degree that an obligated party did not demonstrate full compliance with 
its RVO for the previous year, the shortfall is included as a deficit 
carryover in the calculation. The equation used to calculate the RVO 
for a particular year is shown below:

RVO<INF>i</INF> = Std<INF>i</INF> x GV<INF>i</INF> + D<INF>i</INF>-1

[[Page 55567]]

Where

RVO<INF>i</INF> = The Renewable Volume Obligation for the obligated 
party for year i, in gallons.
Std<INF>i</INF> = The RFS program standard for year i, in percent.
GV<INF>i</INF> = The non-renewable gasoline volume produced by an 
obligated party in year i, in gallons.
D<INF>i</INF>-<INF>1</INF> = Renewable fuel deficit carryover from 
the previous year, in gallons.

    The Energy Act only permits a deficit carryover from one year to 
the next if the obligated party achieves full compliance with its RVO 
including the deficit carryover in the second year. Thus deficit 
carryovers could not occur two years in succession. They could, 
however, occur as frequently as every other year for a given obligated 
party.
    The calculation of an obligated party's RVO is necessarily 
retrospective, since the total gasoline volume that it produces in a 
calendar year will not be known until the year has ended. However, the 
obligated party will have an incentive to project gasoline volumes, and 
thus the RVO, throughout the year so that it can spread its efforts to 
comply across the entire year. Most refiners and importers will be able 
to project their annual gasoline production volumes with a minimum of 
uncertainty based on their historical operations, capacity, plans for 
facility downtimes, knowledge of gasoline markets, etc. Even if 
unforeseen circumstances (e.g., hurricane, unit failure, etc) 
significantly reduced the production volumes in comparison to their 
projections, their RVO would likewise be reduced proportionally and 
their ability to comply with the RFS requirements would be only 
minimally affected. Each obligated party's projected RVO for a given 
year becomes more accurate as that year progresses, but the obligated 
party should nevertheless have a sufficiently accurate estimate of its 
RVO at the beginning of the year to allow it to begin its efforts to 
comply.

B. What Counts as a Renewable Fuel in the RFS Program?

    Section 211(o) of the Clean Air Act defines ``renewable fuel'' and 
specifies many of the details of the renewable fuel program. The 
following section provides EPA's views and interpretations on issues 
related to what fuels may be counted towards compliance with the RVO, 
and how they are counted.
1. What Is a Renewable Fuel That Can Be Used for Compliance?
    The statutory definition of renewable fuel includes cellulosic 
ethanol and waste derived ethanol. It includes biodiesel, as defined in 
the Energy Act.\13\ It also includes all motor vehicle fuels that are 
produced from biomass material such as grain, starch, oilseeds, animal, 
or fish materials including fats, greases and oils, sugarcane, sugar 
beets, tobacco, potatoes or other biomass. In addition, it includes 
motor vehicle fuels made using a feedstock of natural gas if produced 
from a biogas source such as a landfill, sewage waste treatment plant, 
feedlot, or other place where decaying organic material is found.
---------------------------------------------------------------------------

    \13\ As discussed below, for purposes of this rulemaking, the 
regulations separate ``biodiesel'' as defined in the Energy Act, 
into biodiesel (diesels that meet the Energy Act's definition and 
are a mono aklyl ester) and renewable diesel (other diesels that 
meet the Energy Act's definition but are not mono akly esters.
---------------------------------------------------------------------------

    According to the Act, the motor vehicle fuels must be used ``to 
replace or reduce the quantity of fossil fuel present in a fuel mixture 
used to operate a motor vehicle.'' Some motor vehicle fuels can be used 
in both motor vehicles or nonroad engines or equipment. For example, 
highway gasoline and diesel fuel are often used in both highway and 
off-highway applications. Compressed natural gas can likewise be used 
in either highway or nonroad applications. For purposes of the 
renewable fuel program, EPA intends to consider a fuel to be a ``motor 
vehicle fuel'' and to be a ``fuel mixture used to operate a motor 
vehicle,'' based on its potential for use in highway vehicles, without 
regard to whether it in fact is used in a highway or nonroad vehicle. 
If it is a fuel that could be used in highway vehicles, it will satisfy 
these parts of the definition of renewable fuel, whether it is later 
used in highway or nonroad applications. This will allow a motor 
vehicle fuel that otherwise meets the definition to be counted towards 
an RVO without the need to track it to determine its actual application 
in a highway vehicle. This is also consistent with the requirement that 
EPA base the renewable fuel obligation on estimates of the entire 
volume of gasoline consumed, without regard to whether it is used in 
highway or nonroad applications. Fuels that otherwise meet this 
definition but are designated by the producer for use in boilers, or 
heaters, or any use other than highway or nonroad use, would not meet 
the definition of renewable fuel.
    Renewable fuel, as defined, may be made from a number of different 
types of feedstocks. For example, the Fisher-Tropsch process can use 
methane gas from landfills as a feedstock, to produce diesel or 
gasoline. Vegetable oil made from oilseeds such as rapeseed or soybeans 
can be used to make biodiesel or renewable diesel. Methane, made from 
landfill gas (biogas) can be used to make methanol. Also, some 
vegetable oils or animal fats can be processed in distillation columns 
in refineries to make gasoline; as such, the renewable feedstock serves 
as a ``biocrude,'' and the resulting gasoline or diesel product would 
be a renewable fuel. This last example is discussed in further detail 
in Section III.B.3 below.
    As this discussion shows, the definition of renewable fuel in the 
Act is broad in scope, and covers a wide range of fuels. While ethanol 
is used primarily in combination with gasoline, other fuels that meet 
the definition of renewable fuel include biodiesel and various 
alternative fuels that can be used in their neat form, such as ethanol, 
methanol or natural gas, without blending into gasoline and without 
being used to produce a gasoline blending component (such as ETBE). The 
definition of renewable fuel in the Act is not limited to fuels that 
can be blended with gasoline. At the same time, the RFS regulatory 
program is to ``ensure that gasoline sold or introduced into commerce * 
* * contains the applicable volume of renewable fuel.'' This applicable 
volume is specified as a total volume of renewable fuel, in the 
billions of gallons on an aggregate basis. Congress also clearly 
specified that one renewable fuel, biodiesel, could be counted towards 
compliance even though it is not a gasoline component, and does not 
directly displace or replace gasoline. The Act is unclear on whether 
other fuels that meet the definition of renewable fuel, but are not 
used in gasoline, could also be used to demonstrate compliance towards 
the aggregate national use of renewable fuels.
    EPA interprets the Act as allowing regulated parties to demonstrate 
compliance based on any fuel that meets the statutory definition for 
renewable fuel, whether it is directly blended with gasoline or not. 
This would include neat alternative fuels such as ethanol, methanol, 
and natural gas that meet the definition of renewable fuel. This is 
appropriate for several reasons. First, it promotes the use of all 
renewable fuels, which will further the achievement of the purposes 
behind this provision. Congress did not intend to limit the program to 
only gasoline components, as evidenced by the provision for bio-diesel, 
and the broad definition of renewable fuel evidences an intention to 
address more renewable fuels than those used with gasoline. Second, in 
practice EPA expects that the overwhelming volume of renewable fuel 
used to demonstrate compliance with the

[[Page 55568]]

renewable fuel obligation would still be ethanol blended with gasoline. 
Whether one counts or does not count these additional renewable fuels 
would not in practice change whether the total national goal for 
renewable fuel use was met, given the size of the goal specified in the 
Act and the form in which the total is expressed. Finally, as discussed 
later, EPA's compliance program is based on assigning volumes at the 
point of production, and not at the point of blending into motor 
vehicle fuel. This interpretation would avoid the need to track 
renewable fuels downstream to ensure they are blended with gasoline and 
not used in their neat form; the gasoline that is used in motor 
vehicles is reduced by the presence of renewable fuels in the gasoline 
pool whether they are blended with gasoline or not EPA believes its 
proposal is consistent with the intent of Congress and is a reasonable 
interpretation of the Act.
    We are therefore proposing that in addition to any renewable fuels 
that are actually blended into gasoline and are designated for use in a 
highway vehicle, we would also count any renewable fuels falling into 
the following categories as being valid for RFS compliance purposes:
    1. Any renewable fuels used in nonroad applications;
    2. Any renewable fuels used in their neat (unblended) form in 
onroad and nonroad applications; and
    3. Any renewable fuel used in a motor vehicle that does not 
normally run on gasoline. For instance, biogas used in a CNG vehicle, 
or biogenic methanol used in a dedicated methanol vehicle.
    The Agency solicits comment on this approach.
    Under the Act, renewable fuel includes ``cellulosic biomass 
ethanol'' and ``waste derived ethanol'', each of which is defined 
separately. Ethanol can be cellulosic biomass ethanol in one of two 
ways, as described below.
    a. Ethanol Made From a Cellulosic Feedstock. The simplest process 
of producing ethanol is by fermenting sugar in sugar cane, but can also 
be produced from carbohydrates in corn and other feedstocks. This 
process is accomplished by first converting the carbohydrates to sugar. 
Ethanol can also be produced from complex carbohydrates, such as the 
cellulosic portion of plants or plant products. The cellulose is first 
converted to sugars (by hydrolysis); then the same fermentation process 
is used as for carbohydrates to make ethanol. Cellulosic feedstocks 
(composed of cellulose and hemicellulose) are currently more difficult 
and costly to convert to sugar than are carbohydrates because of this 
intermediate conversion step. While the cost and difficulty are a 
disadvantage, the cellulosic process offers the advantage that more 
feedstocks can be used and more volume of ethanol can be produced.
    The Act provides the definition of cellulosic biomass ethanol, 
which states:
    ``The term `cellulosic biomass ethanol' means ethanol derived from 
any lignocellulosic or hemicellulosic matter that is available on a 
renewable or recurring basis, including:
    (i) Dedicated energy crops and trees;
    (ii) Wood and wood residues;
    (iii) Plants;
    (iv) Grasses;
    (v) Agricultural residues;
    (vi) Animal wastes and other waste materials, and
    (viii) Municipal solid waste''
    Examples of cellulosic biomass source material include rice straw, 
switch grass, and wood chips. Ethanol made from these materials would 
qualify under the definition as cellulosic ethanol. In addition to the 
above sources of feedstocks for cellulosic biomass ethanol, the Act's 
definition also includes animal waste, municipal solid wastes, and 
other waste materials While these materials may or may not contain 
cellulosic material, their inclusion in the definition requires that 
ethanol made from such sources be treated as cellulosic biomass ethanol 
under the regulations. ``Other waste materials'' generally includes 
waste material such as sewage sludge, waste candy, and waste starches 
from food production, but for purposes of the definition of cellulosic 
ethanol discussed in III.B.1.b below, it can also mean waste heat 
obtained from an off-site combustion process.
    Although the definitions of ``cellulosic biomass ethanol'' and 
``waste derived ethanol'' both include animal wastes and municipal 
solid waste in their respective lists of covered feedstocks, there 
remains a distinction between these types of ethanol. If the animal 
wastes or municipal solid wastes contain cellulose or hemicellulose, 
the resulting ethanol can be termed ``cellulosic biomass ethanol.'' If 
the animal wastes or municipal solid wastes do not contain cellulose or 
hemicellulose, then the resulting ethanol is labeled ``waste derived 
ethanol.''
    b. Ethanol Made From Any Feedstock in Facilities Run Mostly With 
Biomass-Based Fuel. The definition of cellulosic biomass ethanol in the 
Act also provides that ethanol made at any facility--regardless of 
whether cellulosic feedstock is used or not--may be defined as 
cellulosic if at such facility ``animal wastes or other waste materials 
are digested or otherwise used to displace 90 percent or more of the 
fossil fuel normally used in the production of ethanol.'' The statutory 
language suggests that there are two methods through which ``animal and 
other waste materials'' may be considered for displacing fossil fuel. 
The first method is the digestion of animal wastes or other waste 
materials. EPA proposes to interpret the term ``digestion'' to mean the 
conversion of animal or other wastes into methane, which can then be 
combusted as fuel. We base our interpretation on the practice in 
industry of using anaerobic digesters to break down waste products such 
as manure into methane. Anaerobic digestion refers to the breakdown of 
organic matter by bacteria in the absence of oxygen, and is used to 
treat waste to produce renewable fuels. We note also that the digestion 
of animal wastes or other waste materials to produce the fuel used at 
the ethanol plant does not have to occur at the plant itself. Methane 
made from animal or other wastes offsite and then purchased and used at 
the ethanol plant would also qualify.
    The second method is suggested by the term ``otherwise used'' which 
we propose to interpret as meaning (1) the direct combustion of the 
waste materials as fuel at an ethanol plant, or (2) the use of thermal 
energy that itself is a waste product; e.g., waste heat that is 
obtained from an off-site combustion process such as a neighboring 
plant that has a furnace or boiler from which the waste heat is 
captured. With respect to the first meaning, waste materials from tree 
farms (tops, branches, limbs, etc), or waste materials from saw mills 
(sawdust, shavings and bark) as well as other vegetative waste 
materials such as corn stover, or sugar cane bagasse, could be used as 
fuel for gasifier/boiler units at ethanol plants, since they are waste 
materials and would not be used as a feedstock to carbohydrate-based 
ethanol plants. Although such waste materials conceivably could be 
feedstocks to a cellulosic ethanol plant, its use as a fuel at a 
carbohydrate based ethanol plant does not subvert the intent of the 
definition.\14\
---------------------------------------------------------------------------

    \14\ On the other hand, wood from plants or trees that are grown 
as anenergy crop may not qualify as a waste-derived fuel in an 
ethanol facility because such wood would not qualify as waste 
materials under this portion of the definition. Under the definition 
of renewable fuels and cellulosic biomass ethanol, however, such 
wood material could serve as a feedstock in a cellulosic ethanol 
plant, since these definitions do not restrict such feedstock to 
waste materials only.

---------------------------------------------------------------------------

[[Page 55569]]

    Today's regulations will require owners of ethanol plants to keep 
records of fuel use to ensure compliance with and enforcement of this 
provision of the definition of cellulosic ethanol. Due to potential 
enforcement-related problems associated with application of this 
component of the definition of cellulosic ethanol to foreign 
facilities, we intend for the final rule to develop compliance and 
enforcement related safeguards similar to those set forth in proposed 
80.1165(f), (g), (h) and (j), and with additional inspection, audit, 
recordkeeping and reporting safeguards to verify compliance with the 
requirements on fuel use at foreign facilities. We seek comment on the 
most effective means of doing this. Because of the difficulty of 
implementing these safeguards, however, we also solicit comment on a 
provision that would limit the application of this definition of 
cellulosic ethanol only to ethanol plants in the U.S.
    Regarding the use of waste heat as a source of thermal energy, we 
note that there may be situations in which an off-site furnace, boiler 
or heater creates excess or waste heat that is not used in the process 
for which the thermal energy is employed. For example, a glass furnace 
generates a significant amount of waste heat that often goes unused. We 
are proposing to include waste heat in the definition of ``other waste 
materials'', and also that waste heat captured and used as a source of 
thermal energy in an ethanol plant would satisfy the requirement of 
other waste materials being ``otherwise used'' to make ethanol. 
Although the source of the waste heat is ultimately a fossil fuel in 
most cases, we recognize that without the capture of the heat and 
subsequent use in the ethanol plant, that energy would be unused, and 
the ethanol plant would consume the equivalent amount of fossil fuel. 
Thus, for the same amount of fossil fuel consumption at the off-site 
plant, heat energy capture would result in displacement of fossil fuel 
use at the ethanol plant. Because of potential confusion identifying 
thermal energy that is waste heat from fossil fuel combustion sources 
on site (i.e., at the ethanol plant itself), we are limiting this 
proposal to waste heat captured at off-site plants. The Agency solicits 
comment on our proposal to consider waste heat in the definition of 
``other waste materials''.
    We propose to interpret the term ``fossil fuel normally used in the 
production of ethanol'' to mean fossil fuel used at the facility in the 
ethanol production process itself, rather than other phases such as 
trucks transporting product, and fossil fuel used to grow and harvest 
the feedstock. Therefore the diesel fuel that trucks consume in hauling 
wood waste from sawmills to the ethanol facility would not be counted 
in determining whether the 90% displacement criteria has been met. We 
are interpreting it in this way because we believe the accounting of 
fuel use associated with transportation and other life cycle activities 
would be extremely difficult and in many cases impossible.\15\ The 
Agency solicits comments on this aspect of our approach in accounting 
for fossil fuel displacement.
---------------------------------------------------------------------------

    \15\ In Section IX of today's preamble we discuss our analysis 
of the lifecycle fuel impacts of the RFS rule, with respect to 
greenhouse gas (GHG) emissions. While we do account for fuel used in 
hauling materials to ethanol plant in our analysis, we are using 
average nationwide values, rather than data collected for individual 
plants.
---------------------------------------------------------------------------

    Based on the operation of ethanol plants, we are viewing this 
definition to apply to waste materials used to produce thermal energy 
rather than electrical energy. Electrical usage at ethanol plants is 
used for lights and equipment not related to the production of ethanol. 
Also, the calculation of fossil fuel used to generate such electrical 
usage would be difficult because it is not always possible to track the 
source of electricity that is purchased off-site. We are therefore 
proposing that the displacement of 90 percent of fossil fuels at the 
ethanol plant means those fuels consumed on-site and that are used to 
generate thermal energy used to produce ethanol. The term ``fossil fuel 
normally used in the production of ethanol'' in today's proposal means 
fossil fuel that is combusted at the facility itself to produce thermal 
energy. Owners are required to keep records of fuel (waste-derived and 
fossil fuel) used for thermal energy for verification of their claims. 
They will also be required to track the fossil fuel equivalent of the 
waste heat captured and used in the ethanol process. Since such waste 
heat would typically be purchased through agreement with the off-site 
owner, we do not feel it burdensome for owners to track such 
information. Owners would therefore calculate the amount of energy in 
Btu's associated with waste-derived fuels (including the fossil fuel 
equivalent waste heat), and divided by the total energy in Btus used to 
produce ethanol in a given year. Holders of RINs associated with the 
sale or trade of such cellulosic ethanol would get the benefit of the 
2.5 credit (through 2012 when such credit is valid).
    In the event that the requirements of 90 percent displacement of 
fossil fuel are not met, the owner of a facility producing such ethanol 
would be required to obtain additional RINs to make up whatever deficit 
exists for those RINs sold or traded with a value of 2.5. Assuming this 
is made up, then holders of the RINs associated with the ethanol the 
plant produced in the previous year would not be affected. We solicit 
comment on this proposed approach.
    c. Ethanol that is made from the non-cellulosic portions of animal, 
other waste, and municipal waste. ``Waste derived ethanol'' is defined 
in the Act as ethanol derived from ``animal wastes, including poultry 
fats and poultry wastes, and other waste materials; * * * or municipal 
solid waste.'' Both animal wastes and municipal solid waste are also 
listed as allowable feedstocks for the production of ``cellulosic 
biomass ethanol.'' The determination of the appropriate category of 
ethanol is based on whether the feedstocks on question contain 
cellulose or hemicellulose that is used to make the ethanol. Thus, if 
the ethanol is made from the non-cellulosic portions of animal, other 
waste, or municipal waste, it is labeled ``waste derived ethanol.''
2. What Is Biodiesel?
    The definition of renewable fuel in the Act includes corn-based and 
cellulosic biomass ethanol, waste derived ethanol, and the renewable 
fuel portion of blending components derived from renewable fuel. 
Biodiesel is also specifically named as being included in the Act's 
definition of renewable fuel. The Act states that ``The term `renewable 
fuel' includes * * * biodiesel (as defined in section 312(f) of the 
Energy Policy Act of 1992.'' This definition, as modified by Section 
1515 of the Energy Act states:
    The term ``biodiesel'' means a diesel fuel substitute produced from 
nonpetroleum renewable resources that meets the registration 
requirements for fuels and fuel additives established by the 
Environmental Protection Agency under section 7545 of this title, and 
includes biodiesel derived from animal wastes, including poultry fats 
and poultry wastes, and other waste materials, or municipal solid waste 
and sludges and oils derived from wastewater and the treatment of 
wastewater.
    This definition of biodiesel would include both mono-alkyl esters 
which meet ASTM specification D-6751 \16\ (the most common meaning of 
the term

[[Page 55570]]

``biodiesel'') that have been registered with EPA, and any non-esters 
that are intended for use in engines that are designed to run on 
conventional, petroleum-derived diesel fuel, have been registered with 
the EPA, and are made from any of the feedstocks listed above.
---------------------------------------------------------------------------

    \16\ In the event that the ASTM specification D-6751 is 
succeeded with a different number in the future, EPA may revise the 
regulations accordingly at such time.
---------------------------------------------------------------------------

    To implement the above definition of biodiesel in the context of 
the RFS rulemaking while still recognizing the unique history and role 
of mono-alkyl esters meeting ASTM D-6751, we propose to divide the 
Act's definition of biodiesel into two separate parts: biodiesel (mono-
alkyl esters) and non-ester renewable diesel. The combination of 
``biodiesel (mono-alkyl esters)'' and ``non-ester renewable diesel'' in 
the regulations would fulfill the Act's definition of biodiesel. The 
Agency solicits comment on this approach and specifically asks whether 
the ``non-ester renewable diesel'' definition be referenced explicitly 
to ASTM D-975.
    a. Biodiesel (Mono-Alkyl Esters). Under this part, the term 
``biodiesel (mono-alkyl esters)'' means a motor vehicle fuel which: (1) 
Meets the registration requirements for fuels and fuel additives 
established by the Environmental Protection Agency under section 7545 
of this title (Clean Air Act Section 211); (2) is a mono-alkyl ester; 
(3) meets ASTM specification D-6751-02a; (4) is intended for use in 
engines that are designed to run on conventional, petroleum-derived 
diesel fuel, and (5) is derived from nonpetroleum renewable resources 
including, but not limited to, animal wastes, including poultry fats 
and poultry wastes, and other waste materials, or municipal solid waste 
and sludges and oils derived from wastewater and the treatment of 
wastewater.
    b. Non-Ester Renewable Diesel. The term ``non-ester renewable 
diesel'' means a motor vehicle fuel which: (1) Meets the registration 
requirements for fuels and fuel additives established by the 
Environmental Protection Agency under section 7545 of this title (Clean 
Air Act Section 211); (2) is not a mono-alkyl ester; (3) is intended 
for use in engines that are designed to run on conventional, petroleum-
derived diesel fuel, and (4) is derived from nonpetroleum renewable 
resources including, but not limited to, animal wastes, including 
poultry fats and poultry wastes, and other waste materials, or 
municipal solid waste and sludges and oils derived from wastewater and 
the treatment of wastewater. Current examples of a non-ester renewable 
diesel include: ``renewable diesel'' produced by the Neste process, or 
diesel fuel produced by processing fats and oils through a refinery 
hydrotreating process.
3. Is Motor Fuel That Is Made From a Renewable Feedstock a Renewable 
Fuel?
    We interpret the statutory definition of renewable fuels to include 
all gasoline or diesel that is made from a class of feedstocks called 
``biocrudes'', which are defined as biologically derived feedstocks 
(such as fats and greases). We are providing a definition of 
``biocrude-based renewable fuels'' to mean gasoline or diesel products 
resulting from the processing of biocrudes in production units within 
refineries that process crude oil and other petroleum based feedstocks 
and which make gasoline and diesel fuel.\17\ A particular batch of 
biocrude used as feedstock to a production unit would replace crude oil 
or other petroleum based feedstocks which ordinarily would be the 
feedstock in that process unit. The non-ester renewable diesel defined 
in Section III.B.2.b above could be one such type.
---------------------------------------------------------------------------

    \17\ Biocrude-based renewable fuels will need to be registered 
under the provisions contained in 40 CFR 79 Part 4 before they can 
be sold commercially.
---------------------------------------------------------------------------

    We are assuming that all of the biocrude used as a feedstock in a 
refinery unit will end up as a biocrude-based renewable fuel. Rather 
than requiring the refiner to document what portion of the biocrude-
based renewable fuel is other than diesel or gasoline (e.g., jet fuel), 
we are proposing to have the volume of the biocrude itself count as the 
volume of renewable fuel produced for the purposes of determining the 
volume block codes that are in the RIN (discussed in further detail in 
Section III.D). While this approach may result in some products such as 
jet fuel being counted as renewable fuel, we believe the majority of 
the products produced will be motor vehicle fuel because we assume 
refiners who elect to use biocrudes would do so to help meet the 
requirements of this rule. Furthermore, both diesel and gasoline 
presently make up about 85 percent of the product slate of refineries 
on average. This amount that has been steadily increasing for over 
time, and we expect that the percentage will continue to increase as 
demand for gasoline and diesel increases.
    We are also proposing that the Equivalence Value assigned to 
biocrude-based renewable fuels be designated as 1.0, despite the fact 
that they might warrant a higher value based on their energy content as 
described in the next section.\18\ This approach should balance out the 
likelihood that some of the biocrude-based renewable fuel is not a 
motor vehicle fuel.
---------------------------------------------------------------------------

    \18\ With respect to biodiesel, however, since such fuel is 
typically not made in a traditional petroleum-based refinery, it 
would not be a biocrude-based renewable fuel and would thus not be 
limited to the 1.0 Equivalence Value.
---------------------------------------------------------------------------

4. What Are ``Equivalence Values'' for Renewable Fuel?
    One question that EPA must address is how to count volumes of 
renewable fuel in determining compliance with the renewable volume 
obligation. For instance, the Act stipulates that every gallon of 
cellulosic ethanol should count as if it were 2.5 gallons for RFS 
compliance purposes. The Act does not stipulate similar values for 
other renewable fuels, but as described below we believe it is 
appropriate to do so.
    We are proposing that the ``Equivalence Values'' for different 
renewable fuels be based on their energy content in comparison to the 
energy content of ethanol, and adjusted as necessary for their 
renewable content. The result is an Equivalence Value for corn ethanol 
of 1.0, for biobutanol of 1.3, for biodiesel (mono alkyl ester) of 1.5, 
and for cellulosic ethanol of 2.5. However, the methodology can be used 
to determine the appropriate equivalence value for any other potential 
renewable fuel as well.
    This section describes why we believe that the use of relative 
energy content is appropriate under the Act, and our investigation of 
the alternative use of lifecycle analyses as the basis of Equivalence 
Values.
    a. Authority Under The Act To Establish Equivalence Values. We are 
proposing that Equivalence Values be assigned to every renewable fuel 
to provide an indication of the number of gallons that can be claimed 
for compliance purposes for every physical gallon of renewable fuel. An 
Equivalence Value of 1.0 would mean that every physical gallon of 
renewable fuel would count as one gallon for RFS compliance purposes. 
An Equivalence Value greater than 1.0 would mean that every physical 
gallon of renewable fuel would count as more than one gallon for RFS 
compliance purposes, while a value less than 1.0 would count as less 
than one gallon.
    We are interpreting the Act as allowing EPA to develop Equivalence 
Values according to the methodology discussed below. We believe that 
the use of Equivalence Values is consistent with the intent of Congress 
to treat different renewable fuels differently in different 
circumstances, and to provide

[[Page 55571]]

incentives for use of renewable fuels in certain circumstances, as 
evidenced by those specific circumstances addressed by Congress. The 
Act has several provisions that provide for mechanisms other than 
straight volume measurement to determine the value of a renewable fuel 
in terms of RFS compliance. For example, 1 gallon of cellulosic biomass 
or waste derived ethanol is to be treated as 2.5 gallons of renewable 
fuel. EPA is also required to establish an ``appropriate amount of 
credits'' for biodiesel, and to provide for ``an appropriate amount of 
credit'' for using more renewable fuels than are required to meet your 
obligation. EPA is also to determine the ``renewable fuel portion'' of 
a blending component derived from a renewable fuel. All of these 
statutory provisions provide evidence that Congress did not limit this 
program solely to a straight volume measurement of gallons in the 
context of the RFS program for certain specified circumstances.
    The Act is unclear as to whether a straight gallon measurement is 
required in circumstances other than those specified by Congress. We 
believe the Act can and should be interpreted to allow the use of 
Equivalence Values in those circumstances. First, this is consistent 
with the way Congress treated the various specific circumstances noted 
above, and thus is basically a continuation of that process. Second, 
EPA does not believe that providing such an Equivalence Value for this 
small volume of renewable fuel will interfere in any way with meeting 
the total national volume goals for usage of renewable fuel. We are 
proposing to use an Equivalence Value of 1.0 for ethanol other than 
cellulosic biomass or waste derived ethanol, and we expect that there 
will only be very limited additional situations where an Equivalence 
Value other than 1.0 is used. As a result, this approach is a 
reasonable way for the RFS program to ensure that the total volume of 
renewable fuels will be used as required under the Act.
    b. Energy Content and Renewable Content as the Basis for 
Equivalence Values. We believe it is appropriate to base the 
Equivalence Value assigned to a particular renewable fuel on the degree 
to which the renewable fuel supplants the petroleum content of fuel 
used in a motor vehicle. This is consistent with the Act's definition 
of renewable fuel, which refers to the degree to which it is directly 
used to replace or reduce the quantity of fossil fuel present in a fuel 
mixture used to operate a motor vehicle. The degree to which the fossil 
fuel is replaced is best represented by its relative energy content. To 
appropriately account for the different energy contents of different 
renewable fuels as well as the fact that some renewable fuels actually 
contain some non-renewable content, we propose to calculate Equivalence 
Values using both the renewable content of a renewable fuel and its 
energy content. This section describes our proposal for calculating the 
Equivalence Values.
    In order to take the energy content of a renewable fuel into 
account when calculating the Equivalence Values, we must identify an 
appropriate point of reference. Ethanol would be a reasonable point of 
reference as it is currently the most prominent renewable fuel in the 
transportation sector, and it is likely that the authors of the Act saw 
ethanol as the primary means through which the required volumes would 
be met in at least the first years of the RFS program. By comparing 
every renewable fuel to ethanol on an equivalent energy content basis, 
each renewable fuel could be assigned an Equivalence Value that 
precisely accounts for the amount of petroleum in motor vehicle fuel 
that is reduced or replaced by that renewable fuel in comparison to 
ethanol. To the degree that corn-based ethanol continues to dominate 
the pool of renewable fuel, this approach would allow actual volumes of 
renewable fuel to be consistent with the volumes required by the Act 
while still allowing some renewable fuels to be attributed a higher 
value in terms of RFS compliance to the extent that they have a higher 
energy content than ethanol.
    Equivalence Values should also account for the renewable content of 
renewable fuels, since the presence of any non-renewable content 
impairs the ability of the renewable fuel to replace or reduce the 
quantity of fossil fuel present in a fuel mixture used to operate a 
motor vehicle. The Act specifically states that only the renewable fuel 
portion of a blending component should be considered part of the 
applicable volume under the RFS program. We have interpreted this to 
mean that every renewable fuel should be evaluated at the molecular 
level to distinguish between those components that were derived from a 
renewable feedstock, versus those components that were derived from a 
fossil fuel feedstock. Along with energy content in comparison to 
ethanol, the relative amount of renewable versus non-renewable content 
can then be used directly as the basis for the Equivalence Value.
    We propose that the calculation of Equivalence Values should 
simultaneously take into account both the renewable content of a 
renewable fuel and its energy content in comparison to ethanol. To 
accomplish this, we propose the following formula:

EV = (R<INF>RF</INF> / R<INF>Eth</INF>) x (EC<INF>RF</INF> / 
EC<INF>Eth</INF>)

Where:

EV = Equivalence Value for the renewable fuel.
R<INF>RF</INF> = Renewable content of the renewable fuel, in 
percent.
R<INF>Eth</INF> = Renewable content of ethanol, in percent.
EC<INF>RF</INF> = Energy content of the renewable fuel, in Btu per 
gallon (LHV).
EC<INF>Eth</INF> = Energy content of ethanol, in Btu per gallon 
(LHV).

    R is a measure of that portion of a single renewable fuel molecule 
which can be considered to have come from a renewable source. Since R 
is being combined with relative energy content in the formula above, 
the value of R cannot be based on the weight fraction of the renewable 
atoms in the molecule, but rather must be based on the energy content 
of those atoms. As a result the calculation of R for any particular 
renewable fuel requires an analysis of the chemical process through 
which it was produced. A detailed explanation of calculations for R and 
several examples are given in a technical memorandum in the docket 
\19\.
---------------------------------------------------------------------------

    \19\ ``Calculation of equivalence values for renewable fuels 
under the RFS program'', memo from David Korotney to EPA Air Docket 
OAR-2005-0161.
---------------------------------------------------------------------------

    In the case of ethanol, denaturants are added to preclude its use 
as food. Denaturants are generally a fossil-fuel based, gasoline-like 
hydrocarbon in concentrations of 2-5 volume percent, with 5 percent 
being the most common historical level. In general this would mean that 
the Equivalence Value of ethanol would be 0.95. However, we believe 
that the Equivalence Value for ethanol should be specified as 1.0 
despite the presence of a denaturant. First, as stated above, ethanol 
is expected to dominate the renewable fuel pool for at least the next 
several years, and it is likely that the authors of the Act recognized 
this fact. Thus it seems likely that it was the intent of the authors 
of the Act that each physical gallon of denatured ethanol be counted as 
one gallon for RFS compliance purposes. Second, the accounting of 
ethanol has historically ignored the presence of the denaturant. For 
instance, under Internal Revenue Service (IRS) regulations the 
denaturant can be counted as ethanol by parties filing claims to the 
IRS for the Federal excise tax credit. Also, EIA reporting requirements 
for ethanol producers

[[Page 55572]]

allow them to include the denaturant in their reported volumes.
    Since we are proposing that denatured ethanol be assigned an 
Equivalence Value of 1.0, this must be reflected in the values of 
R<INF>Eth</INF> and EC<INF>Eth</INF>. We have calculated these values 
to be 93.1 percent and 77,550 Btu/gal, respectively. Details of these 
calculations can be found in the aforementioned technical memorandum to 
the docket.
    The calculation of the Equivalence Value for a particular renewable 
fuel can lead to values that deviate only slightly from 1.0, and/or can 
have varying degrees of precision depending on the uncertainty in the 
value of R or EC<INF>RF</INF>. We are therefore proposing three 
simplifications to streamline the application of Equivalence Values in 
the context of the RFS program. First, consistent with our approach to 
the R value for ethanol, we are proposing that all Equivalence Values 
calculated to be in the range of 0.9-1.2 be treated as if they were 
exactly 1.0. This approach would eliminate many of the complexities 
described in Section III.D.2 that are associated with using renewable 
fuels for RFS compliance purposes that have an Equivalence Value other 
than 1.0. Second, we propose that several bins be created for renewable 
fuels with Equivalence Values above 1.0. These bins would replace the 
calculated Equivalence Values with standardized ones to account for 
uncertainty in the calculations as well as to simplify their 
application. We propose that the bins be 1.0, 1.3, 1.5, and 1.7. Each 
renewable fuel would be assigned to the bin that is closest to its 
calculated Equivalence Value. Finally, we propose that all Equivalence 
Values, if any, which are calculated to be less than 0.9 be rounded to 
the first decimal place.
    Using the methodology described above, we calculated the 
Equivalence Values for a number of different renewable fuels expected 
to be in use over the next few years, and modified them according to 
our proposed rounding protocols. These are shown in the table below.

 Table III.B.4-1.--Proposed Equivalence Values for Some Renewable Fuels
------------------------------------------------------------------------
                                                            Equivalence

    Since there are a wide variety of possible renewable fuels that 
could qualify under the RFS program, there may be cases in which a 
party produces a renewable fuel not shown in Table III.B.4-1. In such 
cases we propose to allow the producer to submit a petition to the 
Agency describing the renewable fuel, its feedstock and production 
process, and the calculation of its Equivalence Value. The Agency would 
review the petition and assign an appropriate Equivalence Value to the 
renewable fuel based on the proposed rounding protocols described 
above. Regarding publication of the newly assigned Equivalence Value, 
we could publish it in the Federal Register at the same time as the 
annual standard is published each November. We request comment on 
whether publishing new Equivalence Values in this manner is 
appropriate.
    Regarding biodiesel (mono alkyl esters), we also considered an 
additional approach in setting the Equivalence Value. Since ethanol 
derived from waste products such as animal wastes and municipal solid 
waste will be assigned an Equivalence Value of 2.5 based on a 
requirement in the Act, it might be appropriate to create a parallel 
provision for biodiesel made from wastes. Under this approach, 
biodiesel made from waste products would be assigned an Equivalence 
Value of 2.5 through 2012. Currently, waste products (for example, 
poultry fats and poultry wastes, municipal solid waste, or wastewater 
sludge) make up less than 10 percent of biodiesel feedstocks. This 
approach would have the effect of incentivizing the use of waste 
products and recycled biomass to make biodiesel. Beyond the RFS 
program, it could also set a precedent to promote recycling and waste 
conservation. While we are not proposing to set the Equivalence Value 
for waste-derived biodiesel at 2.5 in today's action, we nevertheless 
believe that this approach has merit and request comment on it.
    c. Lifecycle Analyses as The Basis for Equivalence Values. Although 
we are proposing that Equivalence Values be based on energy content 
relative to ethanol and renewable content, some stakeholders have 
suggested that Equivalence Values should be based on lifecycle 
analyses. Such an approach may have merit, but it would also raise a 
number of challenges. Consequently, we are inviting comment here not 
only on the merit and basis for setting equivalence values on a 
lifecycle basis, but also the appropriate means of doing so.
    Lifecycle analyses involve an examination of fossil fuel used, and 
emissions generated, at all stages of a renewable fuel's life. A 
typical lifecycle analysis examines production of the feedstock, its 
transport to a conversion facility, the conversion of the feedstock 
into renewable motor vehicle fuel, and the transport of the renewable 
fuel to the consumer. At each stage, every activity that consumes 
fossil fuels or results in emissions is quantified, and these energy 
consumption and emission estimates are then summed over all stages. By 
accounting for every activity associated with renewable fuels over 
their entire life, we can assess renewable fuels in terms of not just 
their impact within the transportation sector, but across all sectors, 
and thus for the nation as a whole. In this way they provide a more 
complete picture of the potential impacts of different fuels or 
different fuel sources.
    Advocates for using lifecycle analyses for setting the Equivalence 
Values for different renewable fuels indicate that there could be 
several advantages to this approach. First, doing so could create an 
incentive for obligated parties to choose renewable fuels having a 
greater ability to reduce fossil fuel use or resulting emissions, since 
such renewable fuels would have higher Equivalence Values and thus 
greater value in terms of compliance with the RFS requirements. The 
preferential demand for renewable fuels having higher Equivalence 
Values could in turn spur additional growth in production of these 
renewable fuels. Second, using lifecycle analyses as the basis for 
Equivalence Values could orient the RFS program more explicitly towards 
reducing fossil fuel use or emissions.
    At the same time, the use of lifecycle analyses to establish the 
Equivalence Values for different renewable fuels also raises a number 
of issues. For instance, lifecycle analyses can be conducted using 
several different metrics, including total fossil fuel consumed, 
petroleum energy consumed, criteria pollutant emissions (e.g., VOC, 
NO<INF>X</INF>, PM) carbon dioxide emissions, or greenhouse gas 
emissions. Each metric would result in a different Equivalence Value 
for the same renewable fuel. At the present time there is no consensus 
on which metric would be most appropriate for this purpose.

[[Page 55573]]

    There is also no consensus on the approach to lifecycle analyses 
themselves. Although we have chosen to base our lifecycle analyses on 
Argonne National Laboratory's GREET model for the reasons described in 
Section IX, there are a variety of other lifecycle models and analyses 
available. The choice of model inputs and assumptions all have a 
bearing on the results of lifecycle analyses, and many of these 
assumptions remain the subject of debate among researchers. Lifecycle 
analyses must also contend with the fact that the inputs and 
assumptions generally represent industry-wide averages even though 
energy consumed and emissions generated can vary widely from one 
facility or process to another. There currently exists no single body, 
governmental or otherwise, that has organized a comprehensive dialogue 
among stakeholders about the appropriate tools and assumptions behind 
any lifecycle analyses with the goal of coming to agreement.
    Another issue to using lifecycle analyses as the basis for 
Equivalence Values pertains to the ultimate impact that the RFS program 
would have on petroleum use, fossil fuel use, criteria pollutant 
emissions, and/or emissions of GHGs. With a fixed volume of renewable 
fuel required under the RFS program, any renewable fuel with an 
Equivalence Value greater than 1.0 would necessarily mean that fewer 
actual gallons would be needed to meet the RFS standard. Thus, the 
advantage per gallon may be offset with fewer overall gallons, 
resulting in no overall additional benefit unless the RFS standard was 
simultaneously adjusted.
    Finally, lifecycle analyses of different renewable fuels are likely 
to change over time as farming practices and process technologies 
evolve. Significant changes would necessitate corresponding changes in 
the RFS program to adjust the Equivalence Values on an ongoing basis 
which would add uncertainty into the long-term RIN market.
    We request comment on all issues associated with the use of 
lifecycle analyses in establishing the Equivalence Values for different 
renewable fuels for the RFS program.

C. What Gasoline Is Used To Calculate the Renewable Fuel Obligation and 
Who Is Required To Meet the Obligation?

1. What Gasoline Is Used to Calculate the Volume of Renewable Fuel 
Required To Meet a Party's Obligation?
    The Act requires EPA to promulgate regulations designed to ensure 
that ``gasoline sold or introduced into commerce in the United States 
(except in noncontiguous states or territories)'' contains on an annual 
average basis, the applicable aggregate volumes of renewable fuels as 
prescribed in the Act.\20\ To implement this provision, we are 
proposing that the volume of gasoline used to determined the renewable 
fuel obligation include all finished gasoline, RFG and conventional, 
produced or imported for use in the contiguous United States during the 
annual averaging period. We are also proposing to include in the volume 
of gasoline used to determine the renewable fuel obligation all 
unfinished gasoline that becomes finished gasoline upon the addition of 
oxygenate blended downstream from the refinery or importer. This would 
include both unfinished reformulated gasoline, called ``reformulated 
gasoline blendstock for oxygenate blending,'' or ``RBOB,'' and 
unfinished conventional gasoline (e.g. sub-octane conventional 
gasoline), called ``CBOB.''
---------------------------------------------------------------------------

    \20\ CAA Section 211(o)(2)(A)(i), as added by Section 1501(a) of 
the Energy Policy Act of 2005.
---------------------------------------------------------------------------

    Under the proposed rule, the volume of any other unfinished 
gasoline or blendstock, such as butane, would not be included in the 
volume used to determine the renewable fuel obligation, except where 
the blendstock is combined with other blendstock or finished gasoline 
to produce finished gasoline. Where a blendstock is blended with other 
blendstock to produce finished gasoline, RBOB, or CBOB, the total 
volume of the gasoline blend would be included in the volume used to 
determine the renewable fuels obligation for the blender. Where a 
blendstock is added to finished gasoline, only the volume of the 
blendstock would be included, since the finished gasoline would have 
been included in the compliance determinations of the refiner or 
importer of the gasoline.\21\ Gasoline produced or imported for use in 
a noncontiguous state or U.S. territory \22\ would not be included in 
the volume used to determine the renewable fuels obligation (unless the 
noncontiguous state or territory has opted-in to the RFS program), nor 
would gasoline, RBOB or CBOB exported for use outside the United 
States.
---------------------------------------------------------------------------

    \21\ ``Gasoline treated as blendstock,'' or ``GTAB,'' would be 
treated as any other blendstock with regard to the RFS rule; i.e., 
where the GTAB is blended with other blendstock to produce gasoline, 
the total volume of the gasoline blend, including the GTAB, would be 
included in the volume gasoline used to determine the renewable fuel 
obligation for the blender. Where the GTAB is blended with finished 
gasoline, only the GTAB volume would be included.
    \22\ The noncontiguous states are Alaska and Hawaii. The 
territories are the Commonwealth of Puerto Rico, the U.S. Virgin 
Islands, Guam, American Samoa, and the Commonwealth of the Northern 
Marianas.
---------------------------------------------------------------------------

    For purposes of this preamble, the various gasoline products (as 
described above) that we are proposing to include in the volume of 
gasoline used to determine the renewable fuel obligation are 
collectively called ``gasoline.''
    Generally, ethanol and other renewable fuels would typically be 
used in gasoline, increasing the volume of the entire gasoline blend. 
We are proposing to exclude the volume of renewable fuels contained in 
gasoline from the volume of gasoline used to determine the renewable 
fuels obligation. In implementing the Act's renewable fuels 
requirement, our primary goal is to design a program that is simple, 
flexible and enforceable. If the program were to include renewable 
fuels in the volume of gasoline used to determine the renewable fuel 
obligation, then every blender that blends ethanol downstream from the 
refinery or importer would be subject to the renewable fuel obligation 
for the volume of ethanol that they blend. There are currently 
approximately 1,200 such ethanol blenders. Of these blenders, only 
those who blend ethanol into RBOB are regulated parties under current 
fuels regulations. Designating all of these ethanol blenders as 
obligated parties under the RFS program would greatly expand the number 
of regulated parties and increase the complexity of the RFS program 
beyond that which is necessary to carry out the renewable fuels mandate 
under the Act.
    The Act provides that the renewable fuel obligation shall be 
``applicable to refiners, blenders, and importers, as appropriate.'' 
\23\ For the reasons discussed above, we believe it is appropriate to 
exclude downstream renewable fuel blenders from the group of parties 
subject to the renewable fuel obligation, and to exclude renewable 
fuels from the volume of gasoline used to determine the renewable fuel 
obligation. This exclusion would apply to any renewable fuels that are 
blended into gasoline at a refinery, contained in imported gasoline, or 
added at a downstream blending facility. Thus, for example, any ethanol 
added to RBOB or CBOB downstream from the refinery or importer would be 
excluded from the volume of gasoline used to determine the obligation. 
Any non-renewable fuel added downstream, however, would be included in 
the volume of gasoline used to determine the obligation. This approach 
has no impact on the total

[[Page 55574]]

volume of renewable fuels required, merely on the number of obligated 
parties. We invite comment on the proposal to exclude renewable fuels 
in the volume of gasoline subject to the renewable fuels obligation. As 
discussed earlier, in a similar manner this volume of renewable fuel 
would also be excluded from the calculation performed each year by EPA 
to determine the applicable percentage.
---------------------------------------------------------------------------

    \23\ CAA Section 211(o)(3)(B), as added by Section 1501(a) of 
the Energy Policy Act of 2005.
---------------------------------------------------------------------------

2. Who Is Required To Meet the Renewable Fuels Obligation?
    Under the proposed rule, persons who meet the definition of 
refiner, which includes blenders who produce gasoline by combining 
blendstocks or blending blendstocks into finished gasoline, and persons 
who meet the definition of importer under the fuels regulations would 
be subject to the renewable fuel obligation. As noted above, blenders 
who only blend renewable fuels downstream from the refinery or importer 
would not be subject to the renewable fuel obligation. Any person that 
is required to meet the renewable fuels obligation is called an 
``obligated party.'' We generally refer to all of the obligated parties 
as refiners and importers, as the covered blenders are all refiners 
under the regulations.
    A refiner or importer located in a noncontiguous state or U.S. 
territory would not be subject to the renewable fuel obligation and 
thus would not be an obligated party (unless the noncontiguous state or 
territory opts-in to the RFS program). A party located within the 
contiguous 48 states that ``imports'' into the 48 states gasoline 
produced or imported by a refiner or importer located in a 
noncontiguous state or territory would be an obligated party and must 
meet the renewable fuel obligation for such gasoline.
3. What Exemptions Are Available Under The RFS Program?
    a. Small Refinery and Small Refiner Exemption. The Act provides an 
exemption from the RFS standard for small refineries during the first 
five years of the program. The Act defines small refinery as ``a 
refinery for which the average aggregate daily crude oil throughput for 
a calendar year (as determined by dividing the aggregate throughput for 
the calendar year by the number of days in the calendar year) does not 
exceed 75,000 barrels.'' \24\ Under the proposed rule, any gasoline 
produced at a refinery that qualifies as a small refinery under this 
definition is not counted in determining the renewable fuel obligation 
of a refiner until January 1, 2011. Where a refiner complies with the 
renewable fuel obligation on an aggregate basis for multiple 
refineries, the refiner may exclude from its compliance calculations 
gasoline produced at any refinery that qualifies as a small refinery 
under the RFS program. Beginning in 2011, small refineries would be 
required to meet the same renewable fuel obligation as all other 
refineries. This exemption would apply to any refinery that meets the 
definition of small refinery stated above regardless of the size of the 
refining company that owns the refinery. Based on information currently 
available to us we expect 42 small refineries to qualify for this 
exemption.
---------------------------------------------------------------------------

    \24\ CAA Section 211(o)(a)(9), as added by Section 1501(a) of 
the Energy Policy Act of 2005.
---------------------------------------------------------------------------

    In addition to small refineries as defined in the Act, we are 
proposing to extend this relief to refiners who meet the proposed 
criteria for small refiner status. Under the proposal, a small refiner 
is defined as any refiner who, during 2004: (1) Produces gasoline at a 
refinery by processing crude oil through refinery processing units; (2) 
employs an average of no more than 1,500 people, including all 
employees of the small refiner, any parent company and its subsidiary 
companies; and (3) has a total crude oil processing capability for all 
of the small refiner's refineries of 155,000 barrels per calendar year 
(bpcd). These size requirements were established in prior rulemakings 
and were the result of our analysis of small refiner impacts. We do not 
believe that there are more than three gasoline refineries owned by 
small refiners that meet these criteria and that currently exceed the 
75,000 bpcd crude oil processing capability defined by the Act. We 
request comment on whether a refiner who has a refinery which exceeds 
the 75,000 bpcd criteria should be eligible to apply for a small 
refiner exemption under the RFS program. EPA believes it has this 
discretion in determining an appropriate lead-time for the start-up of 
this program, as well as discretion to determine the regulated 
refiners, blenders and importers, ``as appropriate.''
    We are also proposing to allow foreign refiners to apply for a 
small refinery or small refiner exemption under the RFS program. This 
would apply to foreign refiners that apply for refineries under the 
75,000 bpcd criteria or foreign refiners that apply for small refiner 
status. Under the anti-dumping, MSAT and gasoline sulfur rules, foreign 
refiners are allowed to comply with certain regulations separately from 
any importer. Additional requirements applicable to such foreign 
refiners are included in these rules to ensure that enforcement of the 
regulations at the foreign refinery would not be compromised. We are 
proposing similar enforcement-related requirements that would apply to 
foreign refiners that apply for a small refinery or small refiner 
exemption. Under the existing fuels regulations, few foreign refiners 
have chosen to undertake these additional requirements, and almost all 
gasoline produced at foreign refineries is included in the importers' 
compliance determinations. We invite comment on the value of extending 
the small refinery and small refiner exemptions to foreign refiners 
under the RFS program.
    Under the proposed rule, applications for a small refinery 
exemption must be received by EPA by September 1, 2007 for the 
exemption to be effective in 2007 and subsequent calendar years. The 
application must include documentation that the small refinery's 
average aggregate daily crude oil throughput for calendar year 2004 did 
not exceed 75,000 barrels. As long as the refinery met the criteria in 
2004, it would have the exemption through 2010 regardless of changes in 
crude throughput or ownership. A small refinery exemption would be 
effective 60 days after receipt of the application by EPA unless EPA 
notifies the applicant that the application was not approved or that 
additional documentation is required. We are proposing to base 
eligibility on 2004 data rather than on 2005 data, since it was the 
first full year prior to passage of the Energy Act. In addition, some 
refineries' production may have been affected by Hurricane Katrina in 
2005. We request comment on whether multiple-year average should be the 
basis for eligibility.
    As discussed above, refiners that do not qualify for a small 
refinery exemption under the 75,000 bpcd criteria, but nevertheless 
meet the criteria of a small refiner may apply for small refiner status 
under the RFS rule. The application must be received by EPA by 
September 1, 2007 for the exemption to be effective in 2007 and 
subsequent calendar years. Like the exemption for small refineries, 
small refiner status would be determined based on documentation 
submitted in the application which demonstrates that the refiner met 
the criteria for small refiner status during the calendar year 2004. 
EPA will notify the refiner of approval or disapproval of small refiner 
status by letter. Unlike the case for small refineries, refiners that 
receive approved small refiner status and subsequently do not meet all 
of the criteria for small

[[Page 55575]]

refiner status (i.e., cease producing gasoline from processing crude 
oil, employ more than 1,500 people or exceed the 155,000 bpcd crude oil 
capacity limit) as a result of a merger with or acquisition of or by 
another entity, are disqualified as small refiners, except in the case 
of a merger between two previously approved small refiners. As in other 
EPA programs, where such disqualification occurs, the refiner must 
notify EPA in writing no later than 20 days following the disqualifying 
event.
    The Act provides that the Secretary of Energy must conduct a study 
for EPA to determine whether compliance with the renewable fuels 
requirement would impose a disproportionate economic hardship on small 
refineries. If the study finds that compliance with the renewable fuels 
requirements would impose a disproportionate economic hardship on a 
particular small refinery, EPA is required to extend the small 
refinery's exemption for a period of not less than two additional 
years. The Act also provides that a refiner with a small refinery may 
at any time petition EPA for an extension of the exemption for the 
reason of disproportionate economic hardship. In accordance with these 
provisions of the Act, the proposed rule includes a process by which 
refiners with small refineries may petition EPA for an extension of the 
small refinery exemption. As provided in the Act, the proposed rule 
would require EPA to act on the petition not later than 90 days after 
the date of receipt of the petition.
    During the initial exemption period and any extended exemption 
periods, the gasoline produced by small refineries and refineries owned 
by approved small refiners would be subject to the renewable fuel 
standard.
    Under the proposed rule, the automatic five year exemption for 
small refineries, and any extended exemptions, may be waived upon 
notification to EPA. In waiving its exemption, gasoline produced at a 
small refinery would be included in the RFS program and would be 
included in the gasoline used to determine a refiner's renewable fuel 
obligation. If a refiner waives the exemption for their small refinery 
or their exemption as a small refiner, the refiner would be able to 
separate and transfer RINs like any other obligated party. If a refiner 
does not waive the exemption, the refiner could still separate and 
transfer RINs, but only for the renewable fuel that the refiner itself 
blends into gasoline (i.e. the refiner operates as an oxygenate 
blender).
    b. General Hardship Exemption. In recent rulemakings, we have 
included a general hardship exemption for parties that could 
demonstrate severe economic hardship in complying with the standard. We 
are proposing not to include in the RFS program provisions for a 
general hardship exemption. Unlike most other fuels programs, the RFS 
program includes inherent flexibility since compliance with the 
renewable fuels standard is based on a nationwide trading program, 
without any per gallon requirements, and without any requirement that 
the refiner or importer produce the renewable fuel. By purchasing RINs, 
obligated parties would be able to fulfill their renewable fuel 
obligation without having to make capital investments that may 
otherwise be necessary in order to blend renewable fuels into gasoline. 
We believe that sufficient RINs would be available and at reasonable 
prices, given that EIA projects that far greater renewable fuels will 
be used than required. Given the flexibility provided in the RIN 
trading program, including the provisions for deficit carry-over, and 
the fact that the standard is proportional to the volume of gasoline 
actually produced, we believe that there likely would be no need for a 
general hardship exemption. We request comment on whether there is a 
need to include a general hardship exemption in the RFS program.
    c. Temporary Exemption Based On Unforeseen Circumstances. In recent 
rulemakings, we have also included a temporary exemption based on 
unforeseen circumstances. We are proposing not to include such an 
exemption in the RFS program. The need for such an exemption would 
primarily be based on the inability to comply with the renewable fuels 
standard due to a natural disaster, such as a hurricane. However, in 
the event of a natural disaster, we believe that the volume of gasoline 
produced by an obligated party would also drop, which would result in a 
reduction in the renewable fuel requirement. We believe, therefore, 
that unforeseen circumstances, such as a hurricane or other natural 
disaster, would not result in a party's inability to obtain sufficient 
RINs to comply with the applicable renewable fuels standard. We request 
comment on whether there would be a need to include a temporary 
exemption based on unforeseen circumstances, and, in particular, 
circumstances that may affect ethanol producers.
4. What Are the Opt-In and State Waiver Provisions Under the RFS 
Program?
    a. Opt-in Provisions for Noncontiguous States and Territories. The 
Act provides that, upon the petition of a noncontiguous state or U.S. 
territory, EPA may apply the renewable fuels requirements to gasoline 
produced in or imported into that noncontiguous state or U.S. territory 
at the same time as, or any time after the effective date of the RFS 
program.\25\ In granting such a petition, EPA may issue or revise the 
RFS regulations, establish applicable volume percentages, provide for 
generation of credits, and take other actions as necessary to allow for 
the application of the RFS program in a noncontiguous state or 
territory.
---------------------------------------------------------------------------

    \25\ CAA Section 211(o)(2)(A)(ii), as added by Section 1501(a) 
of the Energy Policy Act of 2005.
---------------------------------------------------------------------------

    Today's proposed rule would implement this provision of the Act by 
providing a process wherein the governor of a noncontiguous state or 
territory may petition EPA to have the state or territory included in 
the RFS program. However, we believe that approval of the petition 
would not require a showing other than a request to be included in the 
program. The petition must be received by EPA on or before October 31 
for the noncontiguous state or territory to be included in the RFS 
program in the next calendar year. A noncontiguous state or territory 
for which a petition is received after October 31 would not be included 
in the RFS program in the next calendar year, but would be included in 
the RFS program in the following year. For example, if EPA receives a 
petition on September 1, 2007, the noncontiguous state or territory 
would be included in the RFS program beginning on January 1, 2008. If 
EPA receives a petition on December 1, 2007, the noncontiguous state or 
territory would be included in the RFS program beginning January 1, 
2009. We believe that requiring petitions to be received by October 31 
would be necessary to allow EPA time to make any adjustments in 
applicable standard. The method for recalculating the renewable fuels 
standard to reflect the addition of a state or territory that has opted 
into the RFS program is discussed in Section III.A.
    Where a noncontiguous state or territory opts-in to the RFS 
program, producers and importers of gasoline for that state or 
territory would be obligated parties subject to the renewable fuel 
requirements. All refiners, blenders and importers who produce or 
import gasoline for use in a state or territory that has opted-in to 
the RFS program would be required to count this volume of gasoline in 
determining their renewable fuel obligation, and would be able to 
separate RINs from batches of renewable fuels used in gasoline that is 
sold or introduced into commerce in the

[[Page 55576]]

state or territory that has opted-in to the RFS program.
    Once a petition to opt-in to the RFS program is approved by EPA, 
the state or territory would remain in the RFS program and be treated 
as any of the 48 contiguous states. We request comment on the opt-in 
provisions.
    b. State Waiver Provisions. The Energy Act provides that EPA, in 
consultation with the U.S. Department of Agriculture (USDA) and the 
Department of Energy (DOE), may waive the renewable fuels requirements 
in whole or in part upon a petition by one or more states by reducing 
the national quantity of renewable fuel required under the Act.\26\ The 
Act also outlines the basic requirements for such a waiver, such as a 
demonstration that implementation of the renewable fuels requirements 
would severely harm the economy or environment of a state, a region, or 
the United States, or that there is an inadequate domestic supply of 
renewable fuel.
---------------------------------------------------------------------------

    \26\ CAA Section 211(o)(7), as added by Section 1501 of the 
Energy Policy Act of 2005.
---------------------------------------------------------------------------

    If EPA approves a state's petition for a waiver of the RFS program, 
the Act stipulates that the national quantity of renewable fuel 
required (Table I.B-1) may be reduced in whole or in part. This 
reduction could reduce the standard applicable to all obligated 
parties. However, there is no provision in the Act that would permit 
EPA to reduce or eliminate any obligations under the RFS program 
specifically for parties located within the state that petitioned for 
the waiver. Thus all refiners, importers, and blenders located in the 
state would still be obligated parties if they produce gasoline. In 
addition, an approval of a state's petition for a waiver may not have 
any impact on renewable fuel use in that state, since it would not be a 
prohibition on the sale or consumption of renewable fuels in that 
state. In fact the Act prohibits the regulations from restricting the 
geographic areas in which renewable fuels may be used. Renewable fuel 
use in the state in question would thus continue to be driven by 
natural market forces.
    Given that state petitions for a waiver of the RFS program are 
unlikely to affect renewable fuel use in that state, we are not 
proposing regulations providing more specificity regarding the criteria 
for a waiver, or the ramifications of Agency approval of such a waiver 
in terms of the level or applicability of the standard. However, states 
can still submit petitions to the Agency for a waiver of the RFS 
requirements under the provision in the Energy Act. We request comment 
on this approach.

D. How Do Obligated Parties Comply With the Standard?

    Under the Act, EPA is to establish a renewable fuel standard 
annually, expressed as a percentage of gasoline sold or introduced into 
commerce, that will ensure that overall a specified total national 
volume of renewable fuels will be used in gasoline in the U.S. The Act 
does not require each obligated party to necessarily do the blending 
themselves in order to comply with this obligation. The Act envisions a 
regulatory program that would ensure the national volume is met as long 
as a refiner or importer ensured that someone used a certain volume of 
renewable fuel, whether it was themselves or another party. Under the 
credit trading program required by the Act, each obligated party is 
allowed to satisfy its obligations either through its own actions or 
through the transfer of credits from others who have more than 
satisfied their individual requirements.
    This section describes our proposed compliance program. It is based 
on the use of unique renewable identification numbers (RINs) assigned 
to batches of renewable fuel by renewable fuel producers. These numbers 
could then be sold or traded, and ultimately used by any obligated 
party to demonstrate compliance with the applicable standard. Excess 
RINs would be identical to the credits envisioned by the Act. As 
described below, we believe that our approach is consistent with the 
language and intent of the Act and preserves the natural market forces 
and blending practices that keep renewable fuel costs to a minimum.
1. Why Use Renewable Identification Numbers?
    Once renewable fuels are produced or imported, there is very high 
confidence they will in fact be blended into gasoline or otherwise used 
as motor vehicle fuels, except for exports. Renewable fuels are not 
used for food, chemicals, or as feedstocks to other production 
processes. In fact the denaturant that must be added to ethanol is 
designed specifically to ensure that the ethanol can be used only as 
motor vehicle fuel. In discussions with stakeholders, it has become 
clear that other renewable fuels, including biodiesel and renewable 
fuels used in their neat (unblended) form, likewise are not used for 
anything other than fuel. Therefore if a refiner ensures that a certain 
volume of renewable fuel has been produced, in effect they have also 
ensured that this volume will be blended into gasoline or otherwise 
used as a motor vehicle fuel. It is therefore appropriate for EPA to 
establish the obligation for refiners and importers as an obligation to 
ensure that a certain volume of renewable fuel has been produced. This 
will ensure that the total required volume of renewable fuels will be 
used in the U.S., and as discussed below has many benefits as far as 
streamlining the program and minimizing disruptions to the current 
marketplace for production, distribution, and use of renewable fuels.
    Implementing a program that is based on ensuring production of a 
certain volume of renewable fuels requires a system of volume 
accounting and tracking of renewable fuels. We propose that this system 
be based on the assignment of unique numbers to each batch of renewable 
fuel. These numbers would be called Renewable Identification Numbers or 
RINs, and would be assigned to each batch by the renewable fuel 
producer or importer.
    The use of RINs would allow the Agency to measure and track 
renewable fuel volumes starting at the point of their production rather 
than at the point when they are blended into conventional fuels. 
Although an alternative approach would be to measure renewable fuel 
volumes as they are blended into conventional gasoline or diesel, 
measuring renewable fuel volumes at the point of production provides 
more accurate measurements that can be easily verified as described in 
Section III.D.1.b below. For instance, ethanol producers are already 
required to report their production volumes to EIA through Monthly 
Oxygenate Reports. This data would provide an independent source for 
verifying volumes. The total number of batches and parties involved is 
also minimized in this approach. The total number of batches is 
smallest at the point of production, since batches are commonly split 
into smaller ones as they proceed through the distribution system to 
the place where they are blended into conventional fuel. The number of 
renewable fuel producers is also far smaller than the number of 
blenders. Currently there are approximately 100 ethanol plants and 40 
biodiesel plants in the U.S., compared with approximately 1200 
blenders.\27\
---------------------------------------------------------------------------

    \27\ Those blenders who add ethanol to RBOB are already 
regulated under our reformulated gasoline regulations.
---------------------------------------------------------------------------

    The assignment of RINs to batches of renewable fuel at the point of 
their production also allows those batches to be identified according 
to various categories important for compliance

[[Page 55577]]

purposes. For instance, the RIN will contain a component that specifies 
whether a batch of ethanol was made from cellulosic feedstocks. This 
RIN component will be of particular importance for 2013 and beyond when 
the Act specifies a national volume requirement for cellulosic biomass 
ethanol. The RIN can also identify the Equivalence Value of the 
renewable fuel which will often only be known at the point of its 
production. Finally, the RIN can identify the year in which the batch 
was produced, a critical element of determining the applicable time 
period within which RINs are valid for compliance purposes.
    Production volumes of renewable fuels intended for blending into 
gasoline are an accurate surrogate for volumes actually blended into 
gasoline. In addition, production volumes of renewable fuels capture 
those renewable fuels used as motor vehicle fuel in their neat 
(unblended) form. Thus we believe that this approach would allow us to 
account for all renewable fuels consumed in the U.S. because renewable 
fuels always end up being used as fuel in the U.S. or exported.
    There are also changes that can occur at various times throughout 
the year in the volumes of renewable fuel that are in storage. These 
stock changes involve the temporary storage of renewable fuel during 
times of excess. However, these stock changes always have a net change 
of zero over the long term since there is no economic benefit to 
stockpiling renewable fuels.
    Exports of renewable fuel represent the only distribution pathway 
that could impair the use of production as a surrogate for renewable 
fuel blending into gasoline or other use as a motor vehicle fuel. 
However, we believe that our proposed approach can account for exports 
through an explicit requirement placed upon exporters (discussed in 
Section III.D.4 below). As a result, we are confident that our proposed 
approach satisfies the statutory obligation that our regulations impose 
obligations on refiners and importers that will ensure that gasoline 
sold or introduced into commerce in the U.S. each year will contain the 
volumes of renewable fuel specified in the Act. By tracking the amount 
of renewable fuel produced or imported, and subtracting the amount 
exported, we will have an accurate accounting of the renewable fuel 
actually consumed as motor vehicle fuel in the U.S. Exports of 
renewable fuel are discussed in more detail in Section III.D.4.
    a. RINs Serve the Purpose of a Credit Trading Program. According to 
the Act, we must promulgate regulations that include provisions for a 
credit trading program. A credit trading program would allow a refiner 
that overcomplied with its annual RVO to generate credits representing 
the excess renewable fuel. The Act stipulates that those credits could 
then be used within the ensuing 12 month period, or transferred to 
another refiner that had not blended sufficient renewable fuel into its 
gasoline to satisfy its RVO. In this way the credit trading program 
would permit current blending practices to continue wherein some 
refiners purchase a significant amount of renewable fuel for blending 
into their gasoline while others do little or none, thus providing a 
means for all refiners to comply with the standard.
    Our proposed RIN-based program would fulfill all the functions of a 
credit trading program, and thus would meet the Act's requirements. If 
at the end of a compliance period, a party had more RINs than it needed 
to show compliance with its renewable volume obligation, these excess 
RINs would serve the function of credits, and could be used, banked, or 
traded in the next compliance period. RINs could be transferred to 
another party in an identical fashion to a credit. However, our 
proposed program provides additional flexibility in that it would 
permit all RINs to be transferred between parties before they were 
deemed to be in excess of a party's annual RVO at the end of the year. 
This is because a RIN serves two functions: it is direct evidence of 
compliance, and after a compliance year is over excess RINs serve the 
function of credits for overcompliance. Thus the RIN approach has the 
advantage of allowing real-time trading without having to wait until 
the end of the year to determine excess.
    As in other motor vehicle fuels credit programs, we are also 
proposing that any renewable producer that generates RINs must use an 
independent auditor to conduct annual reviews of the party's renewable 
production, RIN generation, and RIN transactions. These reviews are 
called ``attest engagements,'' because the auditor is asked to attest 
to the validity of the regulated party's credit transactions. For 
example, the reformulated gasoline program requires attest engagements 
for refiners and importers, and downstream oxygenate blenders to verify 
the underlying documentation forming the basis of the required reports 
(40 CFR part 80, subpart F). In the case of RIN generation, the auditor 
would be required to verify that the number of RINs generated matched 
the volume renewables produced, that any extra value RINs were 
appropriately generated, and that RINs numbers were properly assigned 
and documented on the renewable fuel PTDs as required by the 
regulations.
    b. Alternative Approach To Tracking Batches. If we did not 
implement a RIN-based system for uniquely identifying, measuring, and 
tracking batches of renewable fuel, the RFS program would necessarily 
require that we measure renewable fuel volumes at the point in the 
distribution system where they are actually blended into conventional 
gasoline or diesel or used in their neat form as motor vehicle fuel. 
However, this alternative approach would create a number of significant 
problems.
    First, the parties obligated to meet the standard (refiners, 
importers, and blenders of gasoline) are often not the parties who 
produce renewable fuel or blend renewable fuels such as ethanol into 
gasoline. This separation would require a mechanism for obligated 
parties to obtain credit for renewable fuels blended by non-obligated 
parties. Generally, this would be done through contract management. 
Unfortunately, there might be an incentive to exaggerate the volumes of 
renewable fuel blended and thus exaggerate the number of credits 
generated. This alternative approach might also create opportunities 
for double-counting batches of renewable fuel, either intentionally or 
unintentionally.
    Second, as described in Section I, one of our guiding principles in 
designing the RFS compliance and trading program was to ensure that 
existing business practices could continue to the degree possible. With 
the alternative approach described above, some refiners might have to 
significantly change their business or production practices to take 
greater control of ethanol blending and, therefore, the mechanism for 
compliance with the RFS program. For instance, a refiner could 
establish a contract with an oxygenate blender, securing the rights to 
the credits that oxygenate blender creates. A refiner might also decide 
to take on more blending responsibilities itself. However, these 
approaches would run counter to the normal business practices that keep 
fuel costs to a minimum, and would thus have a tendency to increase 
fuel costs.
    Third, tracking renewable fuel volumes to identify the date, place, 
and volume of blending into gasoline would maximize the number of 
parties involved, overly complicating the compliance system. There are 
approximately 1200 blenders in the U.S. who blend ethanol into 
gasoline, in addition to those that blend biodiesel into conventional 
diesel fuel. Many of

[[Page 55578]]

these parties are small businesses that have not been regulated in an 
EPA fuel program before. Enforcement efforts would necessarily be 
placed on them, imposing upon them the primary burden of accurately 
documenting the volumes of renewable fuel that are blended into 
gasoline even though they are not obligated for meeting the standard. 
In contrast, under our proposed program blenders would only need to 
keep records of RINs acquired with batches. It is our expectation that 
in most cases obligated parties will separate the RINs from batches 
before those batches are transferred to blenders. Therefore, blenders 
will only have to keep records of RINs for a fraction of the renewable 
fuel produced.
    Fourth, a focus on the point of blending would not address 
renewable fuels that need not be blended into gasoline or diesel. For 
example, although biodiesel \28\ is generally blended into conventional 
diesel before being used as fuel, it can be used in its neat form 
(B100). If volumes of renewable fuel were counted only when blending 
into conventional fuel occurred, then B100 could never be claimed by an 
obligated party for RFS compliance purposes. The same would be true of 
other renewable fuels which, although not produced in significant 
quantities today, could play a more substantial role in the renewable 
fuels market in the future. Examples of these other unblended renewable 
fuels could include renewable diesel made by hydrotreating plant oils 
instead of transesterifying them, or a renewable gasoline made from a 
Fischer-Tropsch process applied to biogas.
---------------------------------------------------------------------------

    \28\ Mono-alkyl esters made from plant or animal oils or fats, 
and which have been registered with the EPA for use in highway motor 
vehicles.
---------------------------------------------------------------------------

    Finally, a focus on the point of blending would not permit 
cellulose biomass ethanol to be distinguished from other forms of 
ethanol. Since the Act requires that 250 million gallons of cellulosic 
biomass ethanol be produced starting in 2013, this alternative approach 
would require tracking of batches of renewable fuel at the producer 
level.
    In a blender-based approach, then, special exceptions would need to 
be developed in order for these neat fuels to be available for RFS 
program compliance purposes. For instance, a system of measuring and 
tracking neat renewable fuel volumes at the point of production would 
likely be necessary. This would be no different from a RIN-based 
program for such fuels.
    Our proposed RIN-based program would address all these concerns 
automatically by shifting the focus of accounting to the point of 
production rather than blending. As a result we believe that a blender-
based alternative approach described above is inferior to our proposed 
program. We request comment on a RIN-based system for uniquely 
identifying, measuring, and tracking batches of renewable fuel for 
compliance purposes.
2. Generating RINs and Assigning Them to Batches
    a. Form of Renewable Identification Numbers. Each RIN would be 
generated by the producer or importer of the renewable fuel and would 
uniquely identify not only a specific batch, but also every gallon in 
that batch. The RIN would consist of a 34-character code having the 
following form:

RIN: YYYYCCCCFFFFFBBBBB RRDKSSSSSSEEEEEE

Where:

YYYY = Calendar year of production or import
CCCC = Company ID
FFFFF = Facility ID
BBBBB = Serial batch number
RR = Code identifying the Equivalence Value
D = Code identifying cellulosic biomass ethanol or waste-derived 
ethanol
K = Code identifying extra-value RINs
SSSSSS = Start of volume block.
EEEEEE = End of volume block.

    Some examples of RINs are given in Section III.E.1.b.
    The company and facility IDs would be assigned by the EPA as part 
of the registration process as described in Section IV.B. The serial 
batch number would be chosen by the producer and would generally be a 
sequential value starting with 000001 at the beginning of each year. We 
have chosen five digits for the serial batch number to allow for 
facilities that produce up to a hundred thousand batches per year. 
However, we request comment on whether four digits would be sufficient.
    The RR, D, and K codes would together describe the nature of the 
renewable fuel and the RINs that were generated to represent it. The RR 
code would simply represent the Equivalence Value for the renewable 
fuel, multiplied by 10 to eliminate the decimal place inherent in 
Equivalence Values. Equivalence Values form the basis for the total 
number of RINs that can be generated for a given volume of renewable 
fuel, and are described in Section III.B.4.
    The D code would identify cellulosic biomass ethanol batches as 
such. Since the Act requires that a minimum of 250 million gallons of 
cellulosic biomass ethanol be consumed starting in 2013, obligated 
parties will need to be able to distinguish RINs representing 
cellulosic biomass ethanol from RINs representing other types of 
renewable fuel. This requirement is discussed in more detail in Section 
III.A.
    The K code would be used to specify whether the RIN represents 
actual gallons of renewable fuel, or instead represents extra-value 
RINs. Extra-value RINs arise only in cases where the Equivalence Value 
is greater than 1.0. Extra-value RINs are discussed in more detail in 
Section III.D.2.b below.
    The RIN also contains two values that together identify the total 
number of gallons in a batch as well as uniquely identifying each 
gallon in that batch.\29\ When RINs are first assigned to a batch of 
renewable fuel by its producer or importer, the volume start block for 
that batch will in general be 1 (i.e. SSSSSS will have a value of 
000001). The volume block end is the total volume number of gallons in 
the batch (i.e. for a 10,000 gallon batch, EEEEEE would have a value of 
010000). Thus the single RIN assigned to the batch is in effect 
shorthand for all the unique RINs assigned to every individual gallon 
in the batch. We propose that the number of gallons in a batch be 
standardized to 60 [deg]F to avoid RIN assignment problems associated 
with volume swell due to temperature changes. We have assigned six 
digits to the volume block codes to allow batches up to a million 
gallons in size. We request comment on whether a fewer number of digits 
for the SSSSSS and EEEEEE codes would be sufficient.
---------------------------------------------------------------------------

    \29\ RINs represent actual gallons in a batch when the RIN is a 
standard-value RIN. Extra-value RINs represent additional gallons in 
cases where the Equivalence Value is greater than Equivalence Value 
is greater than 1.0. See further discussion in Section III.D.2.b.
---------------------------------------------------------------------------

    Since ``RIN'' can refer to either the number assigned to the batch 
or the number representing each gallon in that batch, we propose 
distinguishing between a batch-RIN and a gallon-RIN. A batch-RIN would 
be the multi-character code written on a product transfer document 
associated with a batch of renewable fuel. The batch-RIN would include 
SSSSSS and EEEEEE values identifying every (volume-standardized) gallon 
in the batch, each of which would be assigned its own gallon-RIN. A 
gallon-RIN would have identical SSSSSS and EEEEEE values identifying 
one gallon in a batch.
    Our approach to RINs permits the batch to be divided into smaller 
batches at any point in the distribution system while maintaining the 
assignment of unique RINs. For instance, if a 1000 gallon batch of 
renewable fuel is divided into two 500 gallon batches, the volume block 
start and block end values

[[Page 55579]]

in the original batch-RIN would change to reflect the batch split. The 
batch-RIN for the first 500 gallon batch would have an SSSSSS value of 
000001 and an EEEEEE value of 000500, while the second 500 gallon batch 
would have an SSSSSS value of 000501 and an EEEEEE value of 001000. 
Additional batch splits would be handled similarly. More discussion of 
batch splits is provided in Section III.E.1.b.i.
    b. Generating Extra-Value RINs. In general, there is a one-to-one 
correspondence between gallon-RINs and physical gallons of renewable 
fuel in a batch. For instance, a 10,000 gallon batch of renewable fuel 
would be assigned 10,000 gallon-RINs, and the batch-RIN would contain 
volume block start and volume block end values summarizing the 10,000 
gallon-RINs. However, under certain circumstances RINs may be generated 
in addition to those that represent the volume of renewable fuel 
actually produced. This would occur in cases where the Equivalence 
Value of the renewable fuel in question is greater than 1.0. Renewable 
fuel Equivalence Values are discussed in Section III.B.4.
    If a renewable fuel has an Equivalence Value greater than 1.0, the 
incremental value above 1.0 can be used to generate ``extra-value'' 
RINs. For instance, the Equivalence Value for biodiesel shown in Table 
III.B.4-1 is 1.5. If a biodiesel producer made a 1000 gallon batch of 
biodiesel, 1000 standard-value gallon-RINs would be assigned to the 
batch and an additional 500 extra-value gallon-RINs could also be 
generated.
    All the RINs generated to represent a batch of renewable fuel would 
contain the same RR code representing the Equivalence Value of the 
renewable fuel. However, extra-value RINs would be treated differently 
from standard-value RINs in two ways. First, the extra-value RINs would 
include a K code that identifies them as extra-value RINs, 
distinguishing them from standard-value RINs that represent actual 
gallons of renewable fuel. Second, extra-value RINs would not be 
required to be transferred along with the batch of renewable fuel as it 
moves through the distribution system.\30\ Rather, an extra-value RINs 
could be transferred as an independent commodity by the producer. This 
approach would provide an incentive for producers to make renewable 
fuels that have a comparatively greater value in terms of meeting the 
volume requirements of the RFS program. Also, by not requiring extra-
value RINs to be assigned to the batches of renewable fuel that they 
represent, batches of renewable fuel can continue to have a one-to-one 
correspondence between gallon-RINs assigned to the batch and the number 
of physical gallons in that batch. This approach can greatly simplify 
the transfer of RINs with batches particularly when batch splits occur.
---------------------------------------------------------------------------

    \30\ As described in Section III.E below, we are proposing that 
standard-value RINs would be assigned to the batch of renewable fuel 
they represent and would be required to be transferred with the 
batch.
---------------------------------------------------------------------------

    c. Cases in Which RINs Are Not Generated. Although in general every 
(temperature-standardized) gallon of renewable fuel produced or 
imported would be assigned a gallon-RIN, there are several cases in 
which a RIN may not be assigned. For instance, if a renewable fuel 
producer also operated as an exporter, any renewable fuel that it 
produced and exported would not need to be assigned a RIN. Since the 
gasoline that is blended with renewable fuels under the RFS program 
must be ``sold or introduced into commerce'' within the U.S., renewable 
fuels that are exported cannot be claimed by an obligated party for 
compliance purposes, and therefore would not need to be assigned a RIN. 
Exports of renewable fuel are discussed further in Section III.D.4.
    Another case in which a RIN may not be assigned to a batch of 
renewable fuel would be if the renewable fuel was consumed within the 
confines of the production facility where it was made. RINs under 
today's proposal would be assigned to renewable fuel when it leaves the 
production facility. So long as renewable fuel remained at the 
production facility, it would not need to be assigned a RIN.
    A third case in which some renewable fuel would not be assigned a 
RIN would occur for small volume producers. We are proposing that 
renewable fuel producers who produce less than 10,000 gallons in a year 
would not be required to generate RINs or assign them to batches. If 
they chose to register as a renewable fuel producer under the RFS 
program, however, they would be subject to all the regulatory 
provisions that apply to all producers, including the requirement to 
assign RINs to batches. We request comment on the 10,000 gallon 
threshold.
    A fourth case in which some renewable fuel would not be assigned a 
RIN could occur when a gasoline or diesel blending component is only 
partially derived from a renewable source. In such cases the 
Equivalence Value associated with the renewable fuel would be less than 
1.0, indicating that it is produced by combining a renewable fuel with 
a non-renewable fossil fuel. For instance, ethyl tertiary butyl ether 
(ETBE) is made from combining ethanol with isobutylene. The ethanol is 
generally from corn, and the isobutylene is generally from petroleum. 
Equivalence Values are discussed in Section III.B.4. In this situation 
only a fraction of the gallons of renewable fuel produced would be 
assigned a RIN in proportion to its Equivalence Value, with the 
remaining gallons not being assigned a RIN.
    Finally, a renewable fuel whose energy content is less than that of 
ethanol might also be assigned an Equivalence Value less than 1.0, and 
as a result fewer gallon-RINs would be assigned to a batch than 
physical gallons in that batch. For example, methanol made from 
biogenic methane (biogas) for use in a methanol vehicle would have an 
energy content less than that for ethanol. Although methanol is 
currently used as a fuel in only very small quantities, if it was 
produced from renewable feedstocks it would have an Equivalence Value 
less than 1.0.
    If a renewable fuel has a Equivalence Value less than 1.0, then 
gallon-RINs could only be assigned to a portion of the batch. The 
number of gallons within a batch that could be assigned a RIN would be 
calculated from the following formula:

V<INF>a</INF> = EV x V<INF>s</INF>
Where:

V<INF>a</INF> = Volume of the batch that is assigned a RIN, in 
gallons (rounded to the nearest whole gallon).
EV = Equivalence Value for the renewable fuel in question (<1.0).
V<INF>s</INF> = Total volume of the batch standardized to 60 [deg]F, 
in gallons.

    In such cases, the volume block start and volume block end values 
in the batch-RIN (i.e. SSSSSS and EEEEEE codes described in Section 
III.D.2.b) would not exactly correspond to the volume of the batch. 
Instead, they would cover the first portion of the batch. The remaining 
portion of the batch would not be assigned a RIN. For clarity in 
regards to batch splits, a party could assign the gallon-RINs to the 
first-out gallons of the batch. Thus if a batch split occurred, every 
gallon drawn out of the original batch to form a new, smaller batch 
would be assigned a gallon-RIN, up to the point when all the available 
gallon-RINs were assigned to the new batch. Any additional gallons 
drawn out of the original batch, or left with the original batch, would 
have no associated RINs. However, we are not requiring this approach 
but only offer it as one possibility. We propose that parties that have 
ownership or custody of batches of renewable fuel have the discretion 
to split batches and their associated RINs in any way, subject to

[[Page 55580]]

certain restrictions. Batch splits are discussed in more detail in 
Section III.E.1.b.i.
3. Calculating and Reporting Compliance
    Under our proposed program, RINs would form the basis of the volume 
accounting and tracking system that would allow each obligated party to 
demonstrate that they had discharged their renewable fuel obligation. 
This section describes how the compliance process using RINs would 
work. Our proposed approach to the distribution and trading of RINs is 
covered separately in Section III.E below.
    a. Using RINs to Meet the Standard. Under our proposed program, 
each obligated party would determine its Renewable Volume Obligation 
(RVO) based on the applicable percentage standard and its annual 
gasoline volume as described in Section III.A.4. The RVO represents the 
volume of renewable fuel that the obligated party must ensure is 
produced for use in the U.S. in a given calendar year. Since the 
nationwide renewable fuel volumes shown in Table I.B-1 are required by 
the Act to be consumed in whole calendar years, the RVO for each 
obligated party is likewise an obligation that is calculated on an 
annual basis.
    Since our proposed program uses RINs as a measure of the amount of 
renewable fuel used as motor vehicle fuel that is sold or introduced 
into commerce within the U.S., obligated parties would meet their RVO 
through the accumulation of RINs. In so doing, they would effectively 
be causing the renewable fuel represented by the RINs to be consumed as 
motor vehicle fuel. Obligated parties would not be required to 
physically blend the renewable fuel into gasoline or diesel fuel 
themselves. The accumulation of RINs would be the means through which 
each obligated party would show compliance with its RVO, and thus with 
the renewable fuel standard.
    For each calendar year, each obligated party would be required to 
submit a report to the Agency documenting the RINs it acquired, and 
showing that the sum of all gallon-RINs acquired were equal to or 
greater than its RVO. This reporting is discussed in more detail in 
Section IV. In the context of demonstrating compliance, all gallon-RINs 
would have the same compliance value, i.e. there would be no 
distinction between standard-value RINs and extra-value RINs for 
compliance purposes. The Agency could then verify that the RINs used 
for compliance purposes were valid by simply comparing RINs reported by 
producers to RINs claimed by obligated parties. We could also verify 
simply that any given gallon-RIN was not double-counted, i.e., used by 
more than one obligated party for compliance purposes. In order to be 
able to identify the cause of any double-counting, however, additional 
information would be needed on RIN transactions as discussed in Section 
IV.
    If an obligated party has acquired more RINs than it needs to meet 
its RVO, then in general it could retain the excess RINs for use in 
complying with its RVO in the following year, or transfer the excess 
RINs to another party. The conditions under which this would be allowed 
are determined by the valid life of a RIN, described in more detail in 
Sections III.D.3.b below. If alternatively an obligated party has not 
acquired sufficient RINs to meet its RVO, then under certain conditions 
it could carryover a deficit into the next year. Deficit carryovers are 
discussed in more detail in Section III.D.3.d.
    The regulations would prohibit any party from creating or 
transferring invalid RINs. Invalid RIN could not be used in 
demonstrating compliance regardless of the good faith belief of a party 
that the RINs were valid. These enforcement provisions are necessary to 
ensure the RFS program goals are not compromised by illegal conduct in 
the creation and transfer of RINs.
    As in other motor vehicle fuel credit programs, the regulations 
would address the consequences if an obligated party was found to have 
used invalid RINs to demonstrate compliance with its RVO. In this 
situation, the refiner or importer that used the invalid RINs would be 
required to deduct any invalid RINs from its compliance calculations. 
The refiner or importer would be liable for violating the standard if 
the remaining number of valid RINs was insufficient to meet its RVO, 
and the obligated party might be subject to monetary penalties if it 
used invalid RINs in its compliance demonstration. In determining what 
penalty was appropriate, if any, we would consider a number of factors, 
including whether the obligated party did in fact procure sufficient 
valid RINs to cover the deficit created by the invalid RINs, and 
whether the purchaser was indeed a good faith purchaser based on an 
investigation of the RIN transfer. A penalty might include both the 
economic benefit of using invalid RINs and/or a punitive component.
    Although an obligated party would be liable under our proposed 
program for a violation if it used invalid RINs for compliance 
purposes, we would normally look first to the generator/seller of the 
invalid RINs both for payment of penalty and to procure sufficient 
valid RINs to offset the invalid RINs. However, if that party was found 
to be out of business, then attention would turn to the obligated party 
who would have to obtain sufficient valid RINs to offset the invalid 
RINs.
    As for RIN generators, we are proposing that obligated parties be 
required to conduct attest engagements for the volume of gasoline they 
produce and the number of RINs procured to ensure compliance with their 
RVO. In most cases, this should amount to little more than is already 
required under existing EPA gasoline regulations. In the case of 
renewable fuel exporters, the attest engagement would verify the volume 
of renewable fuel exported and therefore the magnitude of their RVO. 
Attest engagement reports would be submitted to the party that 
commissioned the engagement, and to EPA.
    b. Valid Life of RINs. The Act requires that renewable fuel credits 
be valid to show compliance for 12 months as of the date of generation. 
This section describes our proposed interpretation of this provision in 
the context of a RIN-based program. We also discuss some possible 
alternative interpretations that we have considered.
    As described in Section III.D.1.a, credits represent renewable fuel 
volumes in excess of what an obligated party needs to meet their annual 
compliance obligation. Given that the renewable fuel standard is an 
annual standard, compliance would be determined shortly after the end 
of the year, and credits would be identified at that time. Compliance 
is typically demonstrated by submitting a compliance demonstration to 
EPA. Given the 12-month life of a credit as stated in the Act, we 
interpret this provision as meaning that credits would only be valid 
for compliance purposes for the following compliance year. Hence if a 
refiner or importer overcomplied with their 2007 obligation they would 
generate credits that could be used to show compliance with the 2008 
compliance obligation, but the credits could not be used to show 
compliance for later years.
    The Act's limit on credit life helps balance the risks between the 
needs of renewable fuel producers and obligated parties. Producers are 
currently making investments in expanded production capacity on the 
expectation of a statutorily guaranteed minimum market. Under the 
market conditions we are experiencing today that make ethanol use more 
economically attractive, the annual volume requirements in the RFS 
program will not drive consumption of renewable fuels. However, if the 
price of

[[Page 55581]]

crude oil dropped significantly and the use of ethanol in gasoline 
became less economically attractive, obligated parties could use 
stockpiled credits to comply with the program requirements. As a 
result, demand for renewable fuel could fall well below the RFS program 
requirements, and many producers could find themselves with a stranded 
investment. The 12 month valid life limit for credits minimizes the 
potential for this type of result.
    For obligated parties, the 12 month valid life for credits provides 
a window within which parties who do not meet their renewable fuel 
obligation through their own physical use of renewable fuel can obtain 
credits from other parties who have excess. This critical aspect of the 
credit trading system allows the renewable fuels market to continue 
operating according to natural market forces, avoiding the possibility 
that every single refiner would need to purchase renewable fuel for 
blending into its own gasoline. But the 12 month life also provides a 
window within which banking and trading can be used to offset the 
negative effects of fluctuations in either supply of or demand for 
renewable fuels. For instance, if crude oil prices were to drop 
significantly and thus natural market demand for ethanol likewise fell, 
the RFS program would normally bring demand back up to the minimum 
required volumes shown in Table I.B-1. But in this circumstance, the 
use of ethanol in gasoline would be less economically attractive, since 
demand for ethanol would not be following price but rather the 
statutorily required minimum volumes. As a result, the price of RINs, 
and thus ethanol blends, could spike above the levels that would exist 
if no minimum required volumes existed. The 12 month valid life creates 
some flexibility in the market to help mitigate these potential price 
spikes. The renewable fuels market could also experience a significant 
drop in supply if, for instance, a drought were to limit the production 
of the feedstocks needed to produce renewable fuel. Obligated parties 
could use banked credits to comply rather than carry a deficit into the 
next year.
    In the context of our proposed RIN-based program, we are able to 
accomplish the same objective as the Act's 12 month life of credits by 
allowing RINs to be used to show compliance for the year in which the 
renewable fuel was produced and its associated RIN first generated, or 
the following year. RINs not used for compliance purposes in the year 
in which they were generated would by definition be in excess of the 
RINs an obligated party needed in that year, making excess RINs 
equivalent to credits. Excess RINs would be valid for compliance 
purposes in the year following the one in which they initially came 
into existence.\31\ RINs not used within their valid life would expire. 
This would satisfy the Act's 12 month duration for credits.
---------------------------------------------------------------------------

    \31\ The use of previous-year RINs for current year compliance 
purposes would also be limited by the 20 percent RIN rollover cap 
under today's proposal. However, as discussed in the next section, 
we believe that this proposed cap will still provide a significant 
amount of flexibility to obligated parties.
---------------------------------------------------------------------------

    Thus we propose that every RIN be valid for the calendar-year 
compliance period in which it was generated, or the following year. If 
a RIN was created in one year but was not used by an obligated party to 
meet its RVO for that year, the RIN could be used for compliance 
purposes in the next year (subject to certain provisions to address RIN 
rollover as discussed below). If, however, a RIN was created in one 
year and was not used for compliance purposes in that year or in the 
next year, it would expire.
    There are alternative approaches that could be taken to 
establishing the valid life of a RIN. For instance, excess RINs could 
be deemed to be generated not at the end of an annual compliance 
period, but rather on the date that an obligated party must submit its 
annual report to the Agency (February 28 as described in Section 
IV.A.2). In this case the 12-month valid life could extend into the 
following calendar year. As described above, the fact that compliance 
is determined on an annual basis means that RINs that are valid for any 
portion of a calendar year should be available for demonstrating 
compliance with that year's compliance obligation. Under this 
alternative approach, RINs would be valid for three full compliance 
periods: the calendar year in which the original RIN came into 
existence, the following year during which it was deemed to be in 
excess of an obligated party's RVO, and a third year within which the 
12 month valid life expired. We do not believe that this interpretation 
is most consistent with the Act's purposes. This could allow a given 
year's exceptional overcompliance to effectively reduce required 
renewable fuel volumes for two years in the future. We do not believe 
that this would promote the best balance between allowing flexibility 
for obligated parties while also increasing the use of renewable fuels 
annually.
    Another possible approach to RIN life would be to interpret the 
Energy Act's 12-month credit life provision as applying 
retrospectively, not prospectively. Under this approach, the 12-month 
timeframe in the Act would be interpreted to refer to the calendar year 
within which a credit was generated. If excess RINs were deemed to be 
such on December 31, then under this alternative approach no RINs could 
be used for compliance purposes beyond the year in which they 
originally came into existence.
    However, the Act explicitly indicates that obligated parties may 
either use the credits they have generated or transfer them. For a 
party to be able to use credits generated, such credit use must 
necessarily occur in a compliance year other than the one in which the 
credit was generated. Thus we believe that it is appropriate for all 
RINs to be valid for the year in which they were generated and the 
following calendar year. In comparison to a single-year valid life for 
RINs, our proposed approach provides some additional compliance 
flexibility to obligated parties as they make efforts to acquire 
sufficient RINs to meet their RVOs each year. This flexibility will 
have the effect of keeping fuel costs to a minimum.
    We recognize that the language of the Act regarding credit valid 
life is not unequivocal. However, we believe that an interpretation 
leading to a valid life of one year after the year in which the RIN was 
generated is most consistent with the program as a whole. The record of 
the development of this legislation does not provide a clear indication 
to the contrary. In fact, while some stakeholders have argued that the 
Energy Act could have been written to explicitly allow a valid life of 
multiple years if that had been Congress' intent, we believe it could 
likewise have been written to explicitly limit the valid life to the 
year in which the renewable fuel was produced if that had been its 
clear intent. Therefore, the interpretation of the valid life language 
in the Act must be established in the context of the statutory 
requirements for the full RFS program and the practical implications of 
its implementation.
    One possible objection to our proposed approach is that the use of 
RINs generated in one compliance period to satisfy obligations in a 
subsequent compliance period could result in less renewable fuel used 
in a given year than is set forth in the statute. However, the language 
in the Act shows that Congress clearly intended a credit program that 
provided a degree of implementation flexibility. For instance, the 
deficit carryover provision allows any obligated party to fail to meet 
its RVO in one year if it meets the deficit and its RVO in the next 
year. If many obligated parties took advantage of this provision, it 
could

[[Page 55582]]

result in the nationwide total volume obligation for a particular 
calendar year not being met. In a similar fashion, the statutory 
requirement that every gallon of cellulosic biomass ethanol be treated 
as 2.5 gallons for the purposes of compliance means that the annually 
required volumes of renewable fuel could be met in part by virtual, 
rather than actual, volumes. Finally, the calculation of the renewable 
fuel standard is based on projected nationwide gasoline volumes 
provided by EIA (see Section III.A). If the projected gasoline volume 
falls short of the actual gasoline volume in a given year, the standard 
will fail to create the demand for the full renewable fuel volume 
required by the Act for that year. The Act contains no provision for 
correcting for underestimated gasoline volumes.
    We request comment on the valid life of RINs, including our 
proposed approach in which RINs would be valid for the year generated 
or the following year, and the alternative approaches in which RINs 
would be valid for more or less time than under our proposal.
    c. Cap on RIN Use to Address Rollover. As described in Section 
III.D.3.b above, we are proposing that RINs be valid for compliance 
purposes for the calendar year in which they were generated or the 
following year. We believe that this approach is most consistent with 
the Act's prescription that credits be valid for compliance purposes 
for 12 months as of the date of generation. Our proposed approach is 
intended to address both the risk taken by producers expecting a 
guaranteed demand to cover their expanded production capacity 
investments and the risk taken by obligated parties who need a 
guaranteed supply in order to meet their regulatory obligations under 
this program.
    However, the use of previous year RINs to meet current year 
compliance obligations does create an opportunity for effectively 
circumventing the valid life limit for RINs. This can occur in 
situations wherein the total number of RINs generated each year for a 
number of years in a row exceeds the number of RINs required under the 
RFS program for those years. The example below illustrates the issue.

----------------------------------------------------------------------------------------------------------------
a Equivalent to the required volumes shown in Table I.B-1.
b One possible production volume scenario based on EIA projections in their Annual Energy Outlook 2006.

    In this example, there are 0.5 billion more RINs available for 
compliance year 2007 than are needed to comply with the RFS program 
requirements. Since these RINs are not used in the year in which they 
are generated (2007), they can be used for compliance purposes in the 
following year (2008). If they are not used in 2008, they will expire.
    In 2008, 0.6 billion more RINs come into existence than are needed 
to meet the 2008 requirements. This should mean that there are 0.6 
billion more RINs available than are needed to comply with the RFS 
program requirements for 2008, and thus 0.6 billion RINs should be 
carried into 2009. However, since there are also 0.5 billion RINs 
available from the previous year which can be used for compliance 
purposes in 2008, this permits the generation of 0.5 new excess RINs in 
2008 if all the 2007 RINs are used to demonstrate compliance in 2008. 
Thus there are in fact 1.1 billion excess RINs generated in 2008 rather 
than only 0.6 billion, and they can all be used for compliance purposes 
in 2009. In summary, the excess RINs from 2007 were used to generate 
new excess RINs in 2008, and in effect (though not by record) the 
excess RINs from 2007 can be used for compliance purposes in 2009, a 
year after they should have expired. Thus excess RINs have ``rolled 
over'' multiple years.
    The rollover issue essentially could make the applicable valid life 
for RINs virtually meaningless in practice. Even though individual RINs 
technically could only be used for compliance purposes for the year 
generated and the following year, in practice obligated parties could 
use previous-year RINs to generate new excess current-year RINs which 
could then be carried into the following year. This could continue for 
every year in which the volume of renewable fuel produced in a given 
year exceeds the RFS requirements for that year, up to limit of 100 
percent of the standard for that year. The net result is that the RFS 
program could operate as if there was virtually no valid life limit for 
RINs at all.
    RIN rollover also undermines the ability of a limit on credit life 
to guarantee a market for renewable fuels. As described in Section 
III.D.3.b, if the natural market demand for ethanol was higher than the 
volumes required under the RFS program for several years in a row, as 
may occur in practice, obligated parties could amass RINs that, in the 
extreme, could be used entirely in lieu of actually demanding ethanol 
in some subsequent year.
    Some stakeholders do not perceive a problem with the RIN rollover 
issue. They point to the need for maximum flexibility in responding to 
fluctuations in the market, and they are primarily concerned about 
potential supply problems. For instance, if a drought were to reduce 
the availability of corn for ethanol production, there may simply not 
be sufficient RINs available for compliance purposes. A drought 
situation actually occurred in 1996, and as a result 1996 ethanol 
production was 21% less than it had been in 1995. In 1997, production 
had not even returned to the 1995 levels. Although the Agency has the 
authority to waive the required renewable fuel volumes in whole or in 
part in the event of inadequate domestic supply, this can occur only on 
petition by one or more states, and then only after consultation with 
both the Department of Agriculture and the Department of Energy. 
Obligated parties have expressed concern that such a waiver would not 
occur in a timely fashion. The availability of excess previous-year 
RINs would thus provide compliance certainty in the event that the 
supply of current-year RINs falls below the RFS program requirements

[[Page 55583]]

and the Agency does not waive any portion of the program requirements.
    We believe that the rollover issue can and should be addressed. The 
Act's provision regarding the valid life of credits is clearly intended 
to obtain the benefits associated with a limited credit life. Any 
program structure in which some RINs have a de facto infinite life, 
regardless of the technical life of individual RINs, does not 
appropriately achieve the benefits expected from the Act's provision 
regarding the 12-month life of credits. The authority to establish a 
credit program and to implement a limited life for credits includes the 
authority to limit actions that have the practical effect of 
circumventing this limited credit life.
    To be consistent with the Act, we believe that the rollover issue 
should be addressed in our regulations. However, we also believe that 
the limits to preclude such unhindered rollovers should not preclude 
all previous-year RINs from being used for current-year compliance. To 
accomplish this, we must restrict the number of previous-year RINs that 
can be used for current year compliance. We considered a number of 
possible approaches for accomplishing this, some of which are discussed 
below. After consultation with stakeholders, we decided that the best 
approach would be to place a percentage cap on the amount of an 
obligated party's Renewable Volume Obligation (RVO) that can be met 
using previous-year RINs. We are proposing that this cap be set at 20 
percent. Thus each obligated party would be required to use current-
year RINs to meet at least 80 percent of its RVO, with a maximum of 20 
percent being derived from previous-year RINs. The cap would not be 
effective until compliance year 2009, since no rollover is possible in 
years 2007 or 2008.
    Any previous-year RINs that an obligated party may have that are in 
excess of the 20 percent cap could be traded to other obligated parties 
that need them. If the previous-year RINs in excess of the 20 percent 
cap were not used by any obligated party for compliance, they would 
expire. The net result would be that, for the market as a whole, no 
more than 20 percent of a given year's renewable fuel standard could be 
met with RINs from the previous year.
    Furthermore, we believe that the 20 percent cap provides the 
appropriate balance between, on the one hand, allowing legitimate RIN 
carryovers and protecting against potential supply shortfalls that 
could limit the availability of RINs, and on the other hand ensuring an 
annual demand for renewable fuels as envisioned by the Act. We believe 
this approach also provides the certainty all parties desire in 
implementing the program. The same cap would apply equally to all 
obligated parties, and the cap would be the same for all years, 
providing certainty on exactly how obligated parties must comply with 
their RVO going out into the future. A 20 percent cap would be readily 
enforceable with minimal additional program complexity, as each 
obligated party's annual report would simply provide separate listings 
of previous-year and current-year RINs to establish that the cap had 
not been exceeded. A 20 percent cap would have no impact on who would 
own RINs, their valid life, or any other regulatory provision regarding 
compliance.
    Rather than employing a fixed 20 percent cap, we also considered an 
approach whereby we would set the cap annually based on the actual 
excess renewable fuel production. Table III.D.3.c-2 provides an example 
of how the caps would be calculated if the EIA projections for ethanol 
production prove accurate.

a Equivalent to the required volumes shown in Table I.B-1
b Projected ethanol production volumes from EIA, Annual Energy Outlook 2006.
c Example of possible increases in the required volumes. The Energy Act requires at minimum a constant
  percentage of renewable fuel in gasoline after 2012.
d Does not include other renewable fuels such as biodiesel which would increase the excess even further.

    In 2009, for instance, the cap would be 9.8 percent, and by 2012 it 
would be 18.7 percent. Under such an approach, the value of the cap 
might more precisely reflect the actual excess RINs and preclude their 
rollover. However, the annual calculation of the cap would require that 
the total renewable fuel volumes from the previous year be known. For 
compliance year 2009, information on 2008 renewable fuels production 
would not generally be known until spring of 2009. Therefore, obligated 
parties would not know until mid-year at the earliest what the exact 
cap would be for that year. The Agency could publish an estimate of the 
cap by the end of the previous year, but it would not provide obligated 
parties with the certainty they may need for establishing contracts and 
business relationships for RIN trading. In addition, such a variable 
cap may not ensure a smoothly functioning RIN market under all possible 
market conditions. Market flexibility is needed most when the RIN 
market is the tightest (i.e. when renewable fuel production volumes are 
closest to the volumes required under the RFS program). Yet under this 
alternative approach, the cap would be the smallest when supply was 
closest to demand for

[[Page 55584]]

RINs. The cap would approach zero as supply approached the volumes 
required under the RFS program, and thus an obligated party that had 
even a small number of excess RINs from the prior year could not use 
them, but rather would be forced to trade them to someone else. 
Conversely, when supply significantly exceeds demand and market 
flexibility is needed least, the cap would be the highest. Fixing the 
cap at 20 percent both provides certainty to the RIN market, and 
ensures that some minimum level of flexibility exists for individual 
obligated parties even in a market without excess RINs.
    The level of 20 percent is also consistent with both past ethanol 
market fluctuations and future projections of excess ethanol. As 
described above, the largest single-year drop in ethanol supply 
occurred in 1996 and resulted in 21% less ethanol being produced than 
in 1995. While future supply shortfalls may be larger or smaller, the 
circumstances of 1996 provide one example of their potential magnitude. 
Furthermore, as illustrated in Table III.D.3.c-2, EIA projections 
indicate that previous year volumes will exceed current-year 
requirements by roughly 10 to 30 percent between 2009 and 2015. Our 
proposed 20 percent cap lies in the midrange of these values.
    As a result, we believe that a cap of 20 percent appears to be a 
reasonable way to limit RIN rollover and provide some assurances to 
renewable fuel producers regarding demand for renewable fuel. A cap of 
20 percent would also ensure that many previous-year RINs can still be 
used for current year compliance, providing some flexibility in the 
event of market disruptions.
    Despite the flexibility it would provide, a cap of 20 percent would 
not be guaranteed to be sufficient to address every potential future 
supply shortfall or fluctuation in the renewable fuels market. Thus we 
request comment on whether a higher cap, such as 30 percent, would be 
more appropriate. On the other hand, since EIA is projecting that a cap 
of 20 percent will be more than what is necessary in the first few 
years of the program to address rollover, we also request comment on 
whether a smaller cap, such as 10 percent, would be appropriate.
    We also request comment on whether the Agency should adopt a 
provision allowing the cap to be raised in the event that supply 
shortfalls overwhelmed the 20 percent cap. Under this conditional 
provision, the Agency would monitor standard indicators of agricultural 
production and renewable fuel supply to determine if sufficient volumes 
of renewable can be produced to meet the RFS program requirements in a 
given year. Prior to the end of a compliance period, if the Agency 
determined that a supply shortfall was imminent, it could raise the cap 
to permit a greater number of previous-year RINs to be used for 
current-year compliance. Although this approach would not change the 
required volumes, it could create some additional temporary 
flexibility.
    In addition to our proposed 20 percent cap, we also evaluated an 
alternative approach for addressing the RIN rollover issue. Under this 
alternative, we would not employ a uniform cap at all, but rather would 
require current-year RINs to be applied towards an obligated party's 
RVO before any previous-year RINs were considered. This ``last-in, 
first-out'' (LIFO) approach would eliminate the possibility that 
previous-year RINs could be used to generate new excess current-year 
RINs, forcing them to expire. Although it would focus the RIN rollover 
correction on obligated parties and would tailor it to the specific 
circumstances of each party, this alternative approach would also 
create the need for an additional regulatory prohibition. Under this 
approach, RINs held by non-obligated parties would not automatically 
expire. As a result, non-obligated parties could in essence serve as a 
bank of previous-year RINs, thus permitting the rollover to continue 
despite the imposition of a LIFO protocol. To prevent this, the LIFO 
approach would have to include a requirement that non-obligated parties 
be prohibited from owning previous-year RINs. If a non-obligated party 
were to own a current-year RIN on December 31 and hold it until January 
1, that RIN would automatically expire. In order to enforce this 
provision, the Agency would also need to keep track of and receive 
reports on all RIN transactions for non-obligated parties by their 
transaction date.
    Given the additional uncertainty and complexity caused by this 
alternative approach, we believe that our proposed 20 percent cap 
provides the greatest degree of simplicity and flexibility while still 
addressing the RIN rollover issue. However, we request comment on any 
alternative approaches to addressing the RIN rollover issue.
    d. Deficit Carryovers. The Energy Act also contains a provision 
allowing an obligated party to carry a deficit forward from one year 
into the next if it cannot generate or purchase sufficient credits to 
meet its RVO. However, deficits cannot be carried over two years in a 
row.
    Deficit carryovers are measured in gallons of renewable fuel, just 
as for RINs and RVOs. If an obligated party has not acquired sufficient 
RINs to meet its RVO in a given year, the deficit is calculated by 
subtracting the total number of RINs an obligated party has acquired 
from its RVO. There are no volume penalties, discounts, or other 
factors included when calculating a deficit carryover. As described in 
Section III.D.1, the deficit is then added to the RVO for the next 
year. The calculation of the RVO as described in Section III.A.4 shows 
how a deficit would be carried over into the next year:

    RVO<INF>i</INF> = Std<INF>i</INF> x GV<INF>i</INF> + 
D<INF>i-1</INF>

Where:

RVO<INF>i</INF> = The Renewable Volume Obligation for the obligated 
party for year i, in gallons
Std<INF>i</INF> = The RFS program standard for year i, in percent
GV<INF>i</INF> = The non-renewable gasoline volume produced by an 
obligated party in year i, in gallons
D<INF>i-1</INF> = Renewable fuel deficit carryover from the previous 
year, in gallons.

    If an obligated party does acquire sufficient RINs to meet its RVO 
in year i-1, the obligated party must procure sufficient RINs to cover 
the full RVO for year i including the deficit. There are no provisions 
allowing for another year of carryover. If the obligated party does not 
acquire sufficient RINs to meet its RVO for that year plus the deficit 
carryover from the previous year, it would be in noncompliance.
    The Act indicates that deficit carryovers are to occur due to 
``inability'' to generate or purchase sufficient credits. We believe 
that obligated parties will make a determined effort to satisfy their 
RVO on an annual basis, and that a deficit will demonstrate that they 
were unable to do so. Thus, we are not proposing that any particular 
demonstration of ``inability'' be a prerequisite to the ability of 
obligated parties to carry deficits forward. However, we request 
comment on this issue.
4. Provisions for Exporters of Renewable Fuel
    As described in Section III.D.2.a, we believe that U.S. consumption 
of renewable fuel as motor vehicle fuel can be measured with 
considerable accuracy through the tracking of renewable fuel production 
and importing records. This is the basis for our proposed RIN-based 
system of compliance. However, exports of renewable fuel must be 
accounted for under this approach. For instance, if a gallon of ethanol 
is produced in the U.S. but consumed outside of the U.S., the RIN 
associated with that gallon should

[[Page 55585]]

not be valid for RFS compliance purposes since the RFS program is 
intended to require a specific volume of renewable fuel to be consumed 
in the U.S. Exports of renewable fuel currently represent about 5 
percent of U.S. production.
    To ensure that renewable fuels exported from the U.S. cannot be 
used by an obligated party for RFS compliance purposes, the RINs 
associated with that exported renewable fuel must be removed from 
circulation. Ideally the producer of the exported renewable fuel would 
simply not create RINs for those batches. However, in the fungible 
distribution system it is common for exportation of fuel to occur 
without the knowledge of the producer. As a result, we cannot rely on 
the producers to know which batches will be exported and to not 
generate RINs for those batches. Another approach would be to increase 
the obligation placed on refiners, importers, and blenders of gasoline 
based on the volume of renewable fuel exported. Obligated parties would 
thus acquire RINs to meet the standard described in Section III.A, and 
would also be required to acquire RINs to cover the volume of renewable 
fuel exported. However, this approach would not only require an 
estimate of the volume of renewable fuel exported in the next year, but 
would also mean that every obligated party would share in accumulating 
RINs to cover the exports.
    Given these drawbacks, we believe that these two approaches would 
be unworkable. As a result, we believe that it should be the exporter's 
responsibility to account for exported renewable fuel. The most 
straightforward mechanism to accomplish this would be to assign an RVO 
to each exporter that is equal to the annual volume of renewable fuel 
it exported. Just as for obligated parties, then, the exporter would be 
required to acquire sufficient gallon-RINs to meet its RVO. If the 
exporter purchased renewable fuel directly from a producer, that 
renewable fuel would come with associated gallon-RINs which could then 
be applied to its RVO under our proposed program. In this circumstance, 
the exporter would not need to acquire RINs from any other source. If, 
however, the exporter received renewable fuel without the associated 
RINs, it would need to acquire RINs from some other source in order to 
meet its RVO.
    As discussed in Section III.D.2.c, it may be possible to eliminate 
the need for RINs altogether in specific circumstances involving 
exports of renewable fuels. For instance, if the exporter was wholly 
owned by a renewable fuel producer, there would be no need to generate 
RINs for the exported product. Likewise if a renewable fuel producer 
specifically and explicitly earmarked a batch of renewable fuel for 
export, there would be no need for a RIN to be generated. However, in 
both of these cases the producer would need to report the volumes that 
were not assigned a RIN to the EPA in its annual RFS report, along with 
the connection to exports, in order to demonstrate that RINs were 
legitimately not assigned to these batches. We request comment on these 
special-case approaches to exported renewable fuels.
    As described in Section III.D.2, there are cases in which there is 
not a one-to-one correspondence between gallons in a batch of renewable 
fuel and the RINs generated for that batch. For instance, extra-value 
RINs can be generated in cases where the Equivalence Value is greater 
than 1.0. If the RVO assigned to the exporter were based strictly on 
the actual volume of the exported product, it would not capture the 
extra-value RINs which generally are not assigned to batches. Thus we 
propose that the RVO assigned to an exporter be based not on the actual 
volume of renewable fuel exported, but rather on a volume adjusted by 
the Equivalence Value assigned to each batch. The Equivalence Value is 
represented by the RR code within the RIN as described in Section 
III.D.2.a. Thus the exporter would multiply the actual volume of a 
batch by that batch's Equivalence Value to obtain the volume used to 
calculate the RVO.
    In cases wherein an exporter obtains a batch of renewable fuel 
whose RIN has already been separated by an obligated party or blender, 
the exporter may not know the Equivalence Value. We propose that for 
such cases the exporter simply use the actual volume of the batch to 
calculate its RVO. This will introduce some small error into the 
calculation of the RVO for cases in which the renewable fuel had in 
fact been assigned an Equivalence Value greater than 1.0. However, we 
believe that the potential impact of this error would be exceedingly 
small. We request comment on our proposed approach to exporters of 
renewable fuel and any alternative approaches that could ensure that 
production volumes of renewable fuel can be used as an accurate 
surrogate for consumed volumes.
5. How Would the Agency Verify Compliance?
    The primary means through which the Agency would verify an 
obligated party's compliance with its RVO would be the annual reports. 
These reports would include a variety of information required for 
compliance and enforcement, including the demonstration of compliance 
with the previous calendar year's RVO, a list all transactions 
involving RINs, and the tabulation of the total number of RINs owned, 
used for compliance, transferred, retired and expired. Reporting 
requirements for obligated and non-obligated parties are covered in 
detail in Section IV.
    In its annual reports, an obligated party would be required to 
include a list of all RINs held as of the reporting date, divided into 
a number of categories. For instance, a distinction would be made 
between current-year RINs and previous-year RINs as follows:
    Current-year RINs: RINs that came into existence during the 
calendar year for which the report is demonstrating compliance.
    Previous-year RINs: RINs that came into existence in the calendar 
year preceding the year for which the report is demonstrating 
compliance.
    The report would also indicate which RINs were used for compliance 
with the RVO including any potential deficit, which current-year RINs 
were not used for compliance and would therefore be valid for 
compliance the next year, and which previous-year RINs were not used 
for compliance and therefore expired. The report would also include a 
demonstration that the 20 percent cap to address RIN rollover had been 
met, as described in Section III.D.3.c.
    In order to verify compliance for each obligated party, the primary 
Agency activity would involve the validation of RINs. There are four 
basic elements of RIN validation:
    (1) RINs used by an obligated party to comply with its RVO would be 
checked to ensure that they are within their two-year valid life. The 
RIN itself will contain the year of generation, so this check involves 
only an examination of the listed RINs.
    (2) All RINs owned by an obligated party would be cross-checked 
with annual reports from renewable fuel producers to verify that each 
RIN had in fact been generated.
    (3) All RINs used by an obligated party for compliance purposes 
would be cross-checked with annual reports from other obligated parties 
to ensure that no two parties used the same RIN to comply.
    (4) Previous-year RINs used for compliance purposes would be 
checked to ensure that they do not exceed 20 percent of the obligated 
party's RVO.
    In cases where a RIN was highlighted under suspicion of being 
invalid, the Agency would then need to take additional steps to resolve 
the issue. In

[[Page 55586]]

general this would involve a review of RIN transfer records submitted 
to the Agency by all parties in the distribution system that held the 
RINs. RIN transfers would be recorded through EPA's Central Data 
Exchange as described in Section IV. These RIN transfer records would 
permit the Agency to identify all transaction(s) involving the RINs in 
question. Liable parties could then be contacted and appropriate steps 
taken to formally invalidate a RIN improperly claimed by a particular 
party. Additional details of the liabilities and prohibitions 
attributed to parties in the distribution system are discussed in 
Section V.

E. How Are RINs Distributed and Traded?

    Under our proposed program structure, a Renewable Identification 
Number (RIN) would be generated for every gallon of renewable fuel 
produced or imported into the U.S., and would be acquired by obligated 
parties for use in demonstrating compliance with the RFS requirements. 
However, there are a variety of ways in which RINs could be transferred 
from the point of generation by renewable fuel producers to the 
obligated parties that need them.
    EPA's proposal was developed in light of the somewhat unique 
aspects of the RFS program. As discussed earlier, under this program 
the refiners and importers are the parties obligated to comply with the 
renewable fuel requirements. At the same time, refiners and importers 
do not generally produce or blend renewable fuels at their facilities, 
and so are dependent on the actions of others for compliance. Unlike 
EPA's other fuel programs, the actions needed for compliance largely 
center on the production, distribution, and use of a product by parties 
other than refiners and importers. In this context, EPA believes the 
RIN transfer mechanism should focus first on facilitating compliance by 
refiners and importers, and doing that in a way that imposes minimum 
burden on other parties and minimum disruption of current mechanisms 
for distribution of renewable fuels.
    Our proposal does this by relying on the current market structure 
for ethanol distribution and use, and avoiding the need for creation of 
new mechanisms for RIN distribution that are separate and apart from 
this current structure. EPA's proposal would basically have the RIN 
follow with the ethanol until the point the ethanol is purchased by the 
obligated party, or is blended into gasoline by a blender. This 
approach would allow the RIN to be incorporated into the current market 
structure for sale and distribution of ethanol, and would avoid 
requiring refiners to develop and use wholly new market mechanisms. 
While the development of new market mechanisms to distribute RINs is 
not precluded under our proposed program, it is also not required.
    The Agency has also evaluated several other options for 
distributing RINs. We are not proposing these alternatives because they 
tend to require the development of new market mechanisms, as compared 
to relying on the current market structure for distribution of ethanol, 
and they are less focused on facilitating compliance for the obligated 
parties. At the same time, we recognize that all of the alternatives 
described below, as well as our proposal, have differing positive and 
negative aspects, and we invite comment on them, especially comments 
comparing and contrasting them with our proposed program. Our proposal 
is described in subsections 1 through 3 below, and alternative 
approaches in subsection 4.
1. Distribution of RINs With Batches of Renewable Fuel
    We are proposing that standard-value RINs be transferred with 
actual batches of renewable fuel as they move through the distribution 
system, until ownership of the batch is assumed by an obligated party 
or by a party that converts the renewable fuel into motor vehicle fuel. 
After such time, the RINs could be separated from the batch and freely 
traded. This approach would place certain requirements on anyone who 
takes ownership of renewable fuels, including renewable fuel producers, 
importers, marketers, distributors, blenders, and terminal operators.
    a. Responsibilities of Renewable Fuel Producers and Importers. The 
initial generation of RINs and their assignment to specific batches of 
renewable fuel would be the sole responsibility of renewable fuel 
producers and renewable fuel importers. As described in Section 
III.D.1, volumes of renewable fuel can be measured most accurately and 
be more readily verified at these originating locations. They would 
construct each batch-RIN based on the particular circumstances 
associated with each batch, including the creation of a unique serial 
number for the batch and specifying its Equivalence Value. The batch-
RIN would also identify the specific number of gallons in the batch, 
thereby summarizing the gallon-RINs assigned to every gallon in the 
batch. See Section III.D.2.a for details on our proposed format for 
RINs.
    Only standard-value RINs would have to be assigned to batches. 
Extra-value RINs could be generated by the renewable fuel producer in 
cases where the renewable fuel in question has an Equivalence Value 
greater than 1.0 (see Section III.D.2.c for further discussion). 
However, the extra-value RINs would not need to be assigned to the 
batch. Instead, they could be transferred to another party independent 
of the batch. This requirement would in general result in a one-to-one 
correspondence between gallons in a batch and the volume block numbers 
in the batch-RIN assigned to that batch. As a result, the process of 
dividing and combining RINs during batch splits and mergers would be 
simplified, and the fungibility of RINs in the distribution system 
would be maintained. For example, a marketer who took custody of 
ethanol batches from several different producers, including a producer 
of cellulosic biomass ethanol, and combined them all in a single tank 
could then withdraw batches of any size from the tank, and assign a 
number of gallon-RINs to each batch that is equivalent to the number of 
actual gallons in that batch. This approach would also provide an 
incentive for producers to produce renewable fuels with higher 
Equivalence Values, since they could transfer the extra-value RINs to 
any party.
    However, we are also proposing that producers have the option of 
assigning even extra-value RINs to batches if they chose to do so. 
Under these circumstances, the extra-value RINs would be treated just 
like standard-value RINs, and thus would be subject to the same 
limitations on who can separate the RIN from the batch. The assignment 
of extra-value RINs to batches would also mean that the number of 
gallon-RINs assigned to the batch would be greater than the number of 
gallons in the batch. As a result, care would have to be taken during 
batch splits and batch mergers to appropriately pass RINs assigned to a 
parent batch on to the daughter batches. We request comment on allowing 
extra-value RINs to be assigned to batches.
    There are two other cases in which the gallon-RINs assigned to a 
batch would not exactly correspond to the number of gallons in that 
batch. First, if a renewable fuel has an Equivalence Value less than 
1.0, then RINs could only be assigned to a portion of the batch. Such 
potential circumstances are described in Section III.D.2.d. RINs may 
also not correspond exactly to gallons if the density of the batch 
changes due to changes in temperature. For instance, under extreme 
changes in temperature, the volume of a batch of ethanol can change by 
5 percent or more. For this

[[Page 55587]]

reason we are proposing that all batch volumes be corrected to 
represent a standard condition of 60 [deg]F prior to the assignment of 
a RIN. For ethanol,\32\ we propose that the correction be done as 
follows:\33\

    \32\ An appropriate temperature correction for other renewable 
fuels should likewise be used.

Daniels Midland Company, v1.2, 2003.

    V<INF>s,e</INF> = V<INF>a,e</INF> x (-0.0006301 x T + 1.0378)

Where:

V<INF>s,e</INF> = Standard volume of ethanol at 60 [deg]F, in 
gallons.
V<INF>a,e</INF> = Actual volume of ethanol, in gallons.
T = Actual temperature of the batch, in [deg]F.

    Since batches of ethanol are generally sold using standard volumes 
rather than actual volumes, this approach to assigning RINs to batches 
would be consistent with current practices and would maintain the one-
to-one correspondence between the volume block in the batch-RIN and the 
standardized volume of the batch. We propose a similar approach to 
biodiesel, where the volume correction can be calculated using the 
following equation:\34\

gallons.
V<INF>a,b</INF> = Actual volume of biodiesel, in gallons.
T = Actual temperature of the batch, in [deg]F.

    The RIN would have to be assigned to a batch no later than the 
point in time when the batch physically leaves the production or 
importing facility. Although ownership of the batch may be retained by 
the producer or importer, the RIN would nevertheless be required to be 
transferred along with the batch as it leaves the originating facility. 
This requirement would ensure that RINs could be verified against 
production or importing facility records and against mandated reports 
to the Energy Information Administration (EIA). It would also 
centralize the process of assigning RINs to batches.
    The means through which RINs would be transferred with batches 
would in some respects be left to the discretion of the renewable fuel 
producer or importer. The primary requirement would be that the RIN be 
included on a product transfer document (PTD). The PTD can be included 
in any form of standard documentation that is already associated with 
or used to identify title to the batch. The batch documentation must be 
of the sort that uniquely identifies the batch and is generally 
transferred from one party to another, in electronic or paper form, 
when ownership of the batch is transferred. In many cases a bill-of-
lading could serve this purpose. The RIN must be displayed prominently 
on the document when the batch leaves the originating facility, so that 
parties taking ownership of the batch could make a record of this fact 
with specific reference to the RIN. The RIN must be included on a PTD 
whenever ownership or custody of the batch is transferred, until such 
time as the RIN may be separated from the batch as described in Section 
III.E.2. As in other fuels programs, we believe the PTD requirement can 
be met by including the required information generated and transferred 
in the normal course of business.
    RINs would be transferable in the context of the RFS program, and 
except as discussed above, must be transferred along with ownership or 
custody of the batch. The approach that a producer or importer takes to 
the transfer or sale of RINs and batches would be at their discretion, 
under the condition that the two be transferred or sold simultaneously 
and to the same party.
    b. Responsibilities of Parties That Buy, Sell, or Handle Renewable 
Fuels. Batches of renewable fuel can be transferred between many 
different types of parties as they make their way from the production 
or import facilities where they originated to the places where they are 
blended into conventional gasoline or diesel. Some of these parties 
take custody but not ownership of these batches, storing and 
transmitting them on behalf of those who retain ownership. Other 
parties take ownership but not custody, such as a refiner who purchases 
ethanol and has it delivered directly to a blending facility. Thus 
prior to blending, each batch of renewable fuel can be owned or held by 
any number of parties including marketers, distributors, terminal 
operators, and refiners. Under our proposed program, when any party 
takes ownership of a batch of renewable fuel prior to ownership of the 
batch of fuel by an obligated party or blender, the RINs associated 
with that batch must be transferred as well. The RINs would be included 
on PTDs that the party procures when taking ownership of a batch.
    We propose that in general all parties that assume ownership of any 
batch of renewable fuel be required to transfer all RINs assigned to 
that batch to another party to whom ownership of the batch is being 
transferred. Batch splits and batch mergers represent special cases of 
RIN transfers, and are described in more detail below. As described in 
Section III.E.2, the only exception to the requirement that RINs be 
transferred with batches would be parties who are obligated to meet the 
renewable fuel standard, and parties who convert the renewable fuel 
into motor vehicle fuel. Since our proposed program is designed to 
allow RIN transfer and documentation to occur as part of normal 
business practices in the context of renewable fuel distribution, the 
incremental costs of transferring RINs with batches should be minimal. 
Marketers and distributors would simply be adding the batch-RIN to 
transfer documents such as bills-of-lading, and recording the batch-
RINs in their records of batch purchases and sales.
    Under most other credit trading programs, parties obligated to meet 
a standard are also the parties that generate credits for trade. Under 
these systems, non-obligated parties can participate only to the degree 
that obligated parties explicitly include them. In the case of the RFS 
program, however, the production of renewable fuels and their 
conversion into motor vehicle fuel through blending is largely done by 
persons other than obligated parties. To the degree that our proposed 
program allowed the disparity between RFS obligations and the means of 
compliance to continue, stakeholders have expressed concerns about a 
variety of problems that could arise, such as market power by RIN 
sellers in the market where RINs are exchanged. Market power on the 
part of non-obligated parties could result in higher prices for RINs 
than prices that would arise in a competitive, well-functioning market 
setting. For instance, if a renewable fuel producer or marketer could 
separate the batch-RIN from the batch, he could in theory withhold the 
RIN from the marketplace temporarily. By the end of an annual 
compliance period, a scarcity of RINs could increase their price, at 
which point the renewable fuel producers or marketers could begin to 
sell the RINs at an inflated price. In the extreme such parties could 
potentially withhold a large number of RINs from the market, creating a 
scarcity of RINs that could compel obligated parties to purchase 
additional volumes of renewable fuel with associated RINs. These 
scenarios are of particular concern given that we expect there will be 
a relatively small number of renewable fuel producers and marketers 
selling RINs in the

[[Page 55588]]

marketplace. For instance, although there currently exist about 100 
ethanol production facilities in the U.S., nearly half of the 
production volumes come from only seven companies. Likewise, only five 
companies manage the majority of ethanol marketing.
    We believe that the general prohibition against the separation of 
RINs from batches in the distribution system will place only a small 
additional burden on marketers and distributors of renewable fuel. 
According to several stakeholders, a large amount of ethanol is already 
purchased from renewable fuel producers directly by refiners. In these 
cases, the RIN would be transferred directly from the renewable fuel 
producer to an obligated party. For the remaining batches of ethanol 
that do experience multiple transfers before being blended into 
gasoline, the RIN itself would represent a small incremental item of 
information that must be recorded and transferred along with batches 
and could be included in normal business records.
    In addition to the recordkeeping responsibilities described in more 
detail in Section IV, parties that would be required to transfer RINs 
with batches under our proposed program would also have the primary 
responsibility of maintaining the integrity of RIN-batch pairing when 
batches are split or merged. Our proposed approach to these situations 
is described below.
i. Batch splits
    As described in Section III.D.2, batch-RINs assigned to batches of 
renewable fuel would be formatted such that the volume block codes 
(SSSSSS and EEEEEE) would identify every gallon in a batch, and thus 
every gallon-RIN. Thus in most cases there will be a one-to-one 
correspondence between gallons in a batch and the volume block codes 
for the batch-RIN assigned to that batch. If a batch of renewable fuel 
is split into two or more new batches, the gallon-RINs assigned to the 
original batch can be split coincidentally with batch volumes. The 
following example shows how this would be done (volume blocks separated 
for clarity):
    Parent batch:

1000 gallons,
batch-RIN: 2007123412345000011021-000001-001000.

    Daughter batch #1:

600 gallons,
batch-RIN: 2007123412345000011021-000001-000600.

    Daughter batch #2:
100 gallons,
batch-RIN: 2007123412345000011021-000601-000700.

    Daughter batch #3:
300 gallons,
batch-RIN: 2007123412345000011021-000701-001000.

    In this example, the gallon-RINs remain both unique and paired on a 
one-to-one basis with actual gallons even after the parent batch is 
divided into smaller daughter batches.
    However, there will be some cases in which there is not a one-to-
one correspondence between a RIN assigned to a batch and the actual 
gallons in that batch, and such cases could complicate the process of 
splitting batches. For instance, changes in temperature could cause 
batch volumes to swell or shrink. Renewable fuels with Equivalence 
Values less than 1.0, although currently unlikely to arise in 
appreciable volumes, will have more actual gallons in the original 
batch than RINs assigned to that batch. And some producers may choose 
to assign extra-value RINs to batches in cases wherein the Equivalence 
Value is greater than 1.0.
    To address such cases, we propose to allow parties in the 
distribution system the discretion to split batches and their assigned 
RINs following any protocol they choose, as long as that protocol 
preserves the requirement that gallon-RINs that have been assigned to a 
batch by the producer are subsequently assigned to a batch after 
splitting has occurred. Thus regardless of the splitting protocol used, 
no gallon-RINs assigned to a batch could be retained by a party after 
every gallon in that batch has been transferred to another party.
    There are a variety of batch splitting protocols that a party could 
choose from for situations where there is not a one-to-one 
correspondence between the number of gallon-RINs assigned to a batch 
and the number of standardized gallons in that batch. However, we have 
identified two acceptable protocols that we expect most parties to use. 
These are described in Table III.E.1.b.i-1 below. Examples of batch 
splits using both types of splitting protocols are given in Tables 
III.E.1.b.i-2 and III.E.1.b.i-3. We propose that the Proportional 
Protocol be required for cases in which the Equivalence Value of a 
renewable fuel is less than 1.0. For cases in which the Equivalence 
Value is equal to or greater than 1.0, we propose to allow parties the 
flexibility to follow a batch splitting protocol of their own choosing 
so long as there is at least one gallon-RIN for every physical gallon 
in each of the daughter batches. We request comment on these batch 
splitting protocols, any alternative protocols, and the need to codify 
a protocol in the regulations for specific situations.

ii. Batch mergers.
    In general batch mergers will begin with at least two parent 
batches having different RINs. After the merger of the two parent 
batches, the RINs from the two parents would simply need to be listed 
separately on any product transfer documents such as bills-of-lading, 
since they differ not just in the volume block codes but also in other 
aspects of the RIN. We are not proposing any mechanism for simplifying 
the RIN in the case of a batch merger, such as combining two different 
RINs into a single RIN or replacing a collection of different RINs with 
a new single RIN. We believe that such approaches would be likely to 
create significant difficulties in tracking RINs and verifying their 
validity.
    Parties that have two or more batches of renewable fuel that have 
been merged into a single batch will be free to determine how the RINs 
will be subsequently split and assigned to new daughter batches during 
a batch split. We are not proposing a specific protocol for such cases, 
beyond the general requirement that RINs that have been assigned to 
parent batches remain assigned to a daughter batch after splitting has 
occurred. However, it may be helpful for RINs to be ordered on PTDs in 
the order in which the batches were combined, and then assigned to 
daughter batches on a first-in, first-out basis. Thus as individual 
parent batches are added to, for instance, a tank already containing 
renewable fuel, the RINs associated with the newly added batch could be 
added below the existing RINs on the documentation. As product was 
drawn back out of the tank, the RINs assigned to the removed product 
would be those at the top of the list of RINs on the tank 
documentation. This FIFO approach would ensure that RINs assigned to 
parent batches continue to move through the distribution system, and 
batch splits could occur straightforwardly even in cases that begin 
with merged batches. We request comment on whether this FIFO approach 
should remain guidance or whether instead it should be a regulatory 
requirement.
2. Separation of RINs From Batches
    Separation of a RIN from a batch means that the RIN would no longer 
be included on the PTD, and could be traded independently from the 
batch to which it had originally been assigned.
    We believe that the regulatory program should be structured around 
facilitating compliance by obligated parties with their renewable fuel 
obligation. This means that obligated parties should have the right to 
market the renewable fuel separately from the RIN originally assigned 
to it. We are therefore proposing that a refiner or importer would have 
the right to separate the RIN from the batch as soon as he assumes 
ownership of that batch. In the case of ethanol blended into gasoline 
at low concentrations (<= 10 volume percent), stakeholders have 
informed us that a large volume of the ethanol is purchased by refiners 
directly from ethanol producers, and is then passed to blenders who 
carry out the

[[Page 55590]]

blending with gasoline. Therefore, in many cases RINs assigned to 
batches will pass directly from the producers who generated them to the 
obligated parties who need them.
    However, significant volumes of ethanol are also blended into 
gasoline without first being purchased by a refiner. In some cases, the 
blender itself purchases the ethanol. In other cases, a downstream 
customer purchases the ethanol and contracts with the blender to carry 
out the blending. Regardless, the ethanol may never be held or owned by 
an obligated party before it is blended into gasoline. Thus we believe 
that a blender should also have the right to separate the RIN from the 
batch if he actually blends the ethanol into gasoline. This would only 
apply to batches where the RIN had not already been separated by an 
obligated party. Since blenders would in general not be obligated 
parties under our proposed program, blenders who separate RINs from 
batches would have no need to hold onto those RINs and thus could 
transfer them to an obligated party for compliance purposes, or to any 
other party.
    There may be occasions in which a downstream customer actually owns 
the batch of ethanol when it is blended into gasoline. In such cases 
the blender will have custody but not ownership of the batch. We 
propose that the RIN can be separated from the batch of ethanol when 
the batch is blended into gasoline, but the RIN could only be separated 
by the party that owns that batch of renewable fuel at the time of 
blending.
    Once a RIN is separated from a batch of renewable fuel, the PTDs 
associated with that batch could no longer list the RIN. Parties who 
subsequently take ownership of the batch may not know if the RIN had 
been separated, or if a RIN had never been assigned to the batch in the 
first place, contrary to regulatory requirements. To avoid concerns 
about whether RINs assigned to batches have not been appropriately 
transferred with the batch, we request comment on whether PTDs should 
include some notation indicating that the assigned RIN has been 
removed.
    As described in Section III.B, many different types of renewable 
fuel can be used to meet the RFS volume obligations placed upon 
refineries and importers. Currently, ethanol is the most prominent 
renewable fuel, and is most commonly used as a low level blend in 
gasoline at concentrations of 10 volume percent or less. However, some 
renewable fuels can be used in neat form (i.e. not blended with 
conventional gasoline or diesel). The two RIN separation situations 
described above would capture any renewable fuel for which ownership is 
assumed by an obligated party or a party that blends the renewable fuel 
into gasoline or diesel. However, renewable fuels which are used in 
their neat (unblended) form as motor vehicle fuel may not be captured. 
This would include such renewable fuels as neat biodiesel (B100), 
methanol for use in a dedicated methanol vehicle, biogas for use in a 
CNG vehicle, or renewable diesel used in its neat form.
    As for ethanol and biodiesel, neat renewable fuels would be 
assigned a RIN by the producer. However, in cases where the neat 
renewable fuel is never owned by an obligated party or blended into 
gasoline or diesel before being used as a motor vehicle fuel, no party 
would have the right to separate the RIN from the batch. The RIN would 
therefore never become available to an obligated party for RFS 
compliance purposes. Although the current use of these neat renewable 
fuels is minor in comparison to the volumes of ethanol and lower blend 
levels of biodiesel, we nevertheless believe that they should be 
allowed to help meet the volume requirements of the RFS program.
    To address this issue, we propose to more broadly define the right 
to separate a RIN from a batch. In addition to obligated parties and 
blenders, we believe that any party holding a batch of renewable fuel 
for which the RIN has not been separated could separate the RIN from 
the batch if the party designates it for use only as a motor vehicle 
fuel in its neat form and it is in fact only used as such. Given the 
lack of any significant use of ethanol in its neat (but denatured) form 
as a motor vehicle fuel, RINs for neat ethanol could only be separated 
by an obligated party or a party that blends it with gasoline. This 
would include a party that blended ethanol with a small amount of 
gasoline to form E85, since there are millions of vehicles in the fleet 
that can operate on E85. In this case, E85 would be treated like any 
other ethanol/gasoline blend.
    Under our proposed approach, therefore, any party that holds a 
batch of renewable fuel that is typically used in its neat form and was 
designated by the producer for use in its neat form as a motor vehicle 
fuel would be given the right to separate the RIN from the batch. This 
approach would recognize that the neat form of the renewable fuel is 
valid for compliance purposes under the RFS program, as described in 
Section III.B.
    Biodiesel (mono alkyl esters) is one type of renewable fuel that 
can under certain conditions be used in its neat form. However, in the 
vast majority of cases it is blended with conventional diesel fuel 
before use, typically in concentrations of 20 volume percent or less. 
This approach is taken for a variety of reasons, including the 
following:
    <bullet> To reduce impacts on fuel economy.
    <bullet> To mitigate cold temperature operability issues.
    <bullet> To market biodiesel as an additive rather than an 
alternative fuel.
    <bullet> To address concerns of some engine owners or manufacturers 
regarding the impacts of biodiesel on engine durability or drivability.
    <bullet> To reduce the cost of the resulting fuel.
    Biodiesel is also used in low concentrations as a lubricity 
additive and as a means for complying with the ultra-low sulfur 
requirements for highway diesel fuel. Biodiesel is occasionally used in 
its neat form. However, this approach is the exception rather than the 
rule. Consequently, we propose that the RIN assigned to a batch of 
biodiesel could only be separated from that batch if and when the 
biodiesel is blended with conventional diesel. To avoid claims that 
very high concentrations of biodiesel count as a blended product, we 
also propose that biodiesel must be blended into conventional diesel at 
a concentration of 80 volume percent or less before the RIN can be 
separated from the batch.
    Our proposed approach to biodiesel would mean that biodiesel used 
in its neat form would not be valid for compliance purposes under the 
RFS program. To address this issue, we request comment on additionally 
allowing a biodiesel producer to separate the RIN from the batch if it 
could establish that it produced the batch of biodiesel specifically 
for use as motor vehicle fuel in its neat form, and that the biodiesel 
was in fact used in its neat form.
3. Distribution of Separated RINs
    Once a RIN is separated from a batch of renewable fuel, it would 
become freely transferable. Each RIN could be held by any party, and 
transferred between parties any number of times. This approach would 
apply to extra-value RINs (RINs generated based on Equivalence Values 
greater than 1.0) as well as standard-value RINs.
    We are not proposing to limit the number of times that a RIN could 
be transferred, nor the types of parties that could receive or transfer 
RINs. However, this approach would be unique among EPA's fuel 
regulations. For all previous motor vehicle fuel credit trading 
programs we have allowed only refiners and importers to transfer 
credits, and have limited the number of times credits could be 
transferred to one or two

[[Page 55591]]

transfers. This includes, for example, the credit trading programs for 
reformulated gasoline and gasoline sulfur. These limitations were 
included to make the credit trading programs enforceable by making the 
transfer of credits, from the credit generator to the credit user, 
shorter, and populated only by the refiners and importers who were 
obligated to meet those standards. These approaches also helped to 
ensure the validity of credits by limiting the sources of credits to 
companies that the obligated parties know to be reliable business 
partners. A recent report provided to the Agency by the American 
Petroleum institute also provides support for limiting RIN trading to 
obligated parties.\35\ Therefore, we are seeking comment on limiting 
the number of trades and limiting the trades to only occur between 
obligated parties even though we are not proposing to do so here.
---------------------------------------------------------------------------

    \35\ Montgomery, David W., ``Recommendations for a Trading 
Program Which Will Comply with the Renewable Fuel Standard,'' CRA 
International, Inc. May 25, 2006.
---------------------------------------------------------------------------

    For the RFS program, we believe that there is a need to provide for 
this more open trading, and that it can occur without unduly 
sacrificing the enforceability of the program or increasing its 
oversight burden. As described earlier, the RFS program is unique in 
that obligated parties are typically not the ones producing the 
renewable fuels and generating the RINs, so there is a need for trades 
to occur between obligated parties and non-obligated parties. By 
prohibiting anyone except obligated parties from holding RINs after 
they have been separated from a batch, we might be making it more 
difficult for those RINs to eventually be transferred to the obligated 
parties that need them. This is especially important in the case of the 
RFS program, because the program must work efficiently not only for a 
limited number of obligated parties, but a number of non-obligated 
parties as well. A potentially large number of oxygenate blenders, many 
of which will be small businesses, will be looking for ways to market 
their RINs. Furthermore, in some cases renewable fuel producers will 
also have RINs (in particular, extra-value RINs) that can be marketed. 
Allowing other parties, including brokers, to receive and transfer RINs 
may create a more fluid and free market that would increase the venues 
for RINs to be acquired by the obligated parties that need them.
    We believe we can ensure the enforceability of the program despite 
opening up trading to non-obligated parties and allowing multiple 
trades. The RIN number, along with the associated electronic reporting 
mechanism, should allow us the ability to verify the validity of RINs 
and the source of any invalid RINs. Since all RINs generated, traded, 
and used for compliance would be recorded electronically in an Agency 
database, these types of investigations would be straightforward. The 
number of RIN trades, and the parties between whom the RINs are being 
traded, would only have the effect of increasing the size of the 
database.
    As with other credit-trading programs, the business details of RIN 
transactions, such as the conditions of a sale or any other transfer, 
RIN price, role of mediators, etc. would be at the discretion of the 
parties involved. The Agency would be concerned only with information 
such as who holds a given RIN at any given moment, when transfers of 
RINs occur, who the party to the transfers are, and ultimately which 
obligated party relies on a given RIN for compliance purposes. This 
type of information would therefore be the subject of various 
recordkeeping and reporting requirements as described in Section IV, 
and these requirements would generally apply regardless of whether RIN 
has been separated from a batch.
    The means through which RIN trades would occur would also be at the 
discretion of the parties involved. For instance, parties with RINs 
could create open auctions, contract directly with those obligated 
parties who seek RINs, use brokers to identify potential transferees 
and negotiate terms, or just transfer the RINs to any other willing 
party. Brokers involved in RIN transfer could either operate in the 
role of arbitrator without holding the RINs, or alternatively could 
receive the RINs from one party and transfer them to another. If they 
are the transferee of any RINs, they would also be subject to the 
registration, recordkeeping, and reporting requirements. We do not 
believe that it would be appropriate or useful for the EPA to become 
directly involved in RIN transfers, other than in the role of providing 
a database within which transfers can be recorded. Thus EPA would not 
plan on establishing a clearinghouse or centralized brokerage for the 
management of RIN transfers, nor contract with a private firm through 
whom all RIN buyers and sellers would arrange transfers. Our experience 
with other credit trading programs suggests that, left to themselves, 
natural free-market mechanisms will arise to handle RIN transfers, and 
that these mechanisms will maximize the efficiency of the market while 
minimizing the transaction costs for transfers of RINs.
4. Alternative Approaches to RIN Distribution
    During the development of our proposed RFS trading and compliance 
program, stakeholders offered a variety of alternative program design 
approaches. Most of these alternatives recognize the value of a RIN-
based system of compliance, but they differ in terms of which parties 
would be allowed to separate a RIN from a batch and the means through 
which the RINs should be transferred to obligated parties. We invite 
comment on all of these options.
    Our primary concern with the alternative approaches is that we 
believe they would be less effective than our proposed program at 
ensuring that RINs would get to the obligated parties who need them in 
a timely fashion. As described above, stakeholders have expressed 
serious concerns about any program structure that could allow non-
obligated parties to exercise market power in the RIN market, and the 
program we are proposing today is designed to minimize these concerns. 
The alternative approaches described below, in contrast, could 
potentially allow some non-obligated parties who acquire RINs to either 
refuse to transfer them, make them difficult for obligated parties to 
obtain, or drive their price up by exercising market power. We believe 
that these stakeholder concerns about alternative program options are 
legitimate, given that nearly half of the production volumes of ethanol 
come from only seven companies and only five companies manage the 
majority of ethanol marketing. Our proposal also best addresses other 
related issues, such as limiting the number of obligated parties, 
providing for the most open RIN market, and providing an effective 
means at ensuring RIN certainty.
    a. Producer With Direct Transfer of RINs. One alternative to our 
proposed program would allow producers and importers of renewable fuels 
to transfer RINs separately from the renewable fuel that they 
represent. The producer or importer would still generate the RIN, but 
would not necessarily need to assign it to a specific batch of 
renewable fuel. The producer or importer would be required to transfer 
the RIN, but only to an obligated party.
    Under this approach non-obligated parties other than producers and 
importers would have no RIN ownership opportunities and would therefore 
not bear any burden associated with transferring RINs with batches.

[[Page 55592]]

This would eliminate most of the recordkeeping and reporting 
requirements applicable to them under our proposed program. There would 
also be no need for any regulatory requirements to ensure proper 
accounting of RINs as they move through the distribution system, such 
as requirements necessary to address volume changes due to temperature, 
batch splits and mergers, use of renewable fuels in their neat form, 
and the recordkeeping and reporting associated with these requirements.
    The challenges associated with this approach, however, pertain to 
the disconnect between RINs and batches of renewable fuel. For 
instance, the disconnect would produce the possibility for the creation 
of market power with the renewable fuel producer that generates the 
RINs. As discussed above, there is the possibility that renewable 
producers might not place all RINs on the market for procurement by the 
obligated parties, thereby driving up their price and/or increasing 
further the demand for renewables. It is very unlikely that they would 
withhold renewable fuel itself from the market in order to drive up the 
price for it. Not only is storage capacity limited, but there is no 
evidence that ethanol producers or marketers have ever exercised this 
type of market control. This is also true under our proposed program.
    In addition, although a refiner could purchase renewable fuel 
directly from a producer and acquire RINs at the same time, there would 
be many other cases in which a refiner would purchase renewable fuel 
without RINs (such as from a marketer). Although the market would 
likely develop in such a way that renewable fuel without RINs would be 
priced differently than renewable fuels with RINs, the purchase of the 
renewable fuel would still have no bearing on the refiner's RFS 
compliance demonstration, contrary to the intent of the Act. The 
refiner would have to procure RINs separately. If the refiner purchased 
more renewable fuel than it needed for compliance purposes in this way, 
it would not have any excess RINs to transfer to another party. The Act 
stipulates that allowances must be made for credits to be generated for 
excess renewable fuel.
    To address the concern regarding producers withholding RINs from 
the market, under this alternative the renewable producer would be 
required to make the RINs available for transfer to an obligated party. 
As under the proposed option, this RIN transfer could be done in one of 
several ways, such as through direct contract or a restricted 
clearinghouse. Any RINs not provided directly to an obligated party 
would then need to be made available through a regularly scheduled 
public auction to the highest bidder. This could be through an existing 
internet auction Web site, or through another auction mechanism 
implemented by a generator so long as the mechanism is equally open and 
available to all obligated parties. Only obligated parties would be 
permitted to bid on the RINs in such an auction.
    To ensure the effectiveness of such an approach, however, there are 
a number of additional aspects of the program that would need to be 
specified. Since a renewable producer could essentially withhold RINs 
from the market by setting the selling price too high, such an approach 
would hinge upon any such auctions occurring without any minimum price 
for the RINs. Producers would be required to transfer RINs to the 
highest bidder regardless of the bid price, even if there was only a 
single bidder. The renewable producer would be required to send the 
successful bidder a written confirmation of the RIN transfer, including 
the RIN identification numbers. If there were no bids, the renewable 
producer would be required to roll them over to subsequent auction 
cycles until such time as the RINs were no longer valid for compliance 
purposes and they would simply be retired. Finally, in order to ensure 
that RINs were actually being made available, such sales, trades, or 
auctions would be required to occur at least quarterly, but we seek 
comment on whether a shorter cycle would be more appropriate.
    Various other aspects of the RIN auctions or transactions would 
also have to be specified. For example, the location, time, and other 
details of any auction would have to be made widely known to obligated 
parties in sufficient time for them to participate. To this end, the 
rule could specify that there must be advance public notice of the 
intent to conduct an auction and the auction procedures, and that this 
notice must be advertised through nationwide media or a public Internet 
posting. The minimum amount of advance notice could be, for example, 
one week or four weeks. The regulations could require that the RINs be 
transferred in large enough blocks, such as 5,000 RINs, in order to 
prevent undue transaction costs. The regulations could also specify the 
time period during which any public auction must remain open; seven 
days could be specified, for example. Other criteria for how the 
auction is conducted could be included in order to ensure its 
legitimacy. Interested commenters should include details for RIN 
auctions or transactions that they believe should be addressed in 
implementing regulations.
    Our proposed program is designed to ensure that the existing market 
mechanisms for the distribution of renewable fuel can be used for the 
distribution of RINs as well. The need for independent RIN markets is 
minimized, and likewise the regulatory oversight of such markets is 
minimized. Under the direct transfer alternative described above, 
however, not only does an independent RIN market become a central 
feature of the RFS program, but the regulations might need to specify 
the many various aspects of RIN transfers as described above, and doing 
so would represent an intervention into the market that the Agency has 
not exercised before. It may be necessary to design the regulatory 
provisions in this way in order to have an enforceable program under 
this alternative, but we would have to be convinced that such an 
approach could be properly structured and that it was superior to other 
alternatives.
    Under this option, non-obligated parties such as marketers or 
brokers would not be allowed to own RINs. It could be possible to add 
in this flexibility, but in effect this option would then operate 
similarly to our proposed approach, but with additional complications 
and transaction costs due to the fact RINs would not follow batches 
through the distribution system. Therefore, we do not believe it is 
appropriate to provide this flexibility as part of the direct-transfer 
option.
    b. Producer With Open RIN Market. Another approach would allow 
producers and importers of renewable fuels to transfer RINs separately 
from the renewable fuel to any party. If a renewable fuel producer did 
choose to transfer the RIN with the batch, any downstream party would 
have the right to separate that RIN from the batch.
    Although we believe that the recordkeeping burden placed upon 
marketers and distributors under our proposed program would be minimal, 
this alternative approach would essentially eliminate that burden 
altogether. Marketers and distributors would not have to ensure that 
RINs were transferred with batches and keep a record of those 
transfers, and would not be responsible for ensuring that RINs remain 
assigned to batches during batch splits and mergers. Any marketer or 
distributor that did receive a batch with an assigned RIN could 
separate the RIN from the batch and transfer it, maximizing the choices 
available to them.

[[Page 55593]]

    However, this alternative approach would increase the burdens for 
obligated parties to comply with their renewable fuel obligation since 
all RINs would be controlled by producers and marketers at the point of 
generation. The concerns described above regarding the exercising of 
market power in the RIN market by a small number of non-obligated 
parties would apply to this alternative. Although these concerns may be 
less significant under EIA's current projections that renewable fuel 
production volumes will exceed the RFS program requirements, we believe 
that we should design the RFS program to function smoothly under any 
future market scenario. Since it is possible that the market conditions 
leading to EIA's projections could change, we believe that the concern 
about producers and marketers exercising market power in the RIN market 
is important. As a result, we do not believe that this alternative 
approach is most appropriate.
    c. First Purchaser. As under our proposed approach, in this 
alternative the renewable fuel producer would be required to assign a 
RIN to every batch of renewable fuel and to transfer that RIN with the 
batch. However, the first party in the distribution system to take 
ownership of the batch would have the right to separate the RIN from 
the batch. This means that any non-obligated party that purchased the 
renewable fuel from its producer would be able to separate the RIN and 
to transfer it independently from the batch.
    The advantage of this alternative approach, as compared to our 
proposal, is that it would remove control of the sale of RINs from the 
producers. However, the concern raised by refiners about the exercise 
of market power in the RIN market remains because only five companies 
today manage the majority of ethanol marketing in the U.S. With such a 
small number of companies, any one could exert a controlling influence 
on the RIN market. In addition, many large producers operate as 
marketers for other smaller producers, allowing some producers to be 
the first purchaser. As discussed for the previous alternative, we 
believe that we should design the RFS program to function smoothly 
under any future market scenario, including ones different from those 
forming the basis of the current EIA projections. Thus we believe that 
the concern about marketers exercising market power in the RIN market 
is still important, and as a result we do not believe that the first 
purchaser approach offers significant advantages over our proposed 
program.
    d. Owner at Time of Blending. An alternative approach to our 
proposed option of allowing obligated parties to separate RINs as soon 
as they gain ownership would prohibit all parties from separating a RIN 
from a batch of renewable fuel until the batch had actually been 
blended into gasoline or diesel. The obligated party could retain the 
RIN as soon as it gained ownership of the batch, but could not transfer 
the RIN or use it for compliance purposes until the renewable fuel that 
it represented was actually blended into gasoline or diesel. Thus, a 
RIN could be separated from the batch of renewable fuel to which it has 
been assigned only at the time of blending, and whomever owns the batch 
at the time of blending would also have the right to separate the RIN 
and use or transfer it.
    Although we based our proposed program design on the expectation 
that all renewable fuels will eventually be consumed as fuel, primarily 
through blending with conventional gasoline or diesel, this alternative 
approach would provide direct verification of blending. However, we do 
not believe that this is necessary in order to provide an enforceable 
program, and in fact it would create an additional and unnecessary 
burden for blenders.
    As discussed in Section III.D, it is not necessary to track 
renewable fuels all the way to the point of blending because we can 
confidently treat production volumes as an accurate surrogate for 
consumption. This fact provides the basis for our proposed program, and 
could also be used in support of the alternatives described previously. 
If verification of blending were required before a RIN could be 
separated from a batch, both obligated parties and blenders would be 
subject to additional recordkeeping and paperwork burdens. The Agency 
would be compelled to enforce activities at the blender level, adding 
about 1200 parties to the list of those subject to enforcement under 
our proposed program.
    By requiring refiners to wait until renewable fuel is blended 
before they can separate the RIN, this alternative approach could limit 
the potential for one refiner to purchase large volumes of renewable 
fuel with the intent of separating the RINs and exercising market power 
in the RIN market. However, we do not believe that this represents an 
advantage to this alternative since it could not occur under our 
proposed program either. There are no geographic limitations to RIN 
transfers within the 48 contiguous states, so obligated parties that 
need RINs can purchase them from any refiner who has an excess. In 
addition, RINs that have been separated from their assigned batches by 
oxygenate blenders represent an additional safety valve in the RIN 
market, providing additional assurances that no one refiner could 
exercise market power in the RIN market, thereby demanding an 
unreasonably high price for them.
    For these reasons, we do not believe that requiring renewable fuel 
to be blended into gasoline or diesel before a RIN could be separated 
from the batch would provide any significant advantages over our 
proposed program. However, we request comment on this alternative 
approach.
    e. Blender at Time of Blending. Although we have concluded that 
production volumes are an accurate surrogate for consumption, thus 
eliminating the need to measure renewable fuel volumes at the point of 
blending into gasoline or diesel, an alternative approach would do just 
that.
    In this alternative program approach, RINs would not be generated 
by the producer of the renewable fuel and assigned to batches. Instead, 
blenders would keep detailed records of the volumes of renewable fuel 
that they blended into gasoline or diesel, and would generate credits 
for those volumes. Blenders would be considered obligated parties, but 
their obligation would be considered as zero percent to avoid redundant 
obligations (i.e., to avoid the blender being responsible for blending 
renewable fuel into gasoline for which a refiner or importer also has 
an RFS program responsibility). Thus they would generate credits which 
could then be sold to a refiner or importer who needs it for compliance 
purposes.
    The blender approach would differ from our proposed program and all 
the other alternative approaches in that it would be based on actual 
blending activity, as compared to ownership of the renewable fuel. 
Under this alternative approach, the blender would not use records of 
batch ownership to establish generation of credits, but rather would be 
required to demonstrate that it had actually blended the renewable fuel 
into gasoline or diesel. Since the blender was responsible for 
blending, the blender would generate the credits from that blending and 
would have the right to transfer them to another party.
    Although blenders could use IRS fuel credit forms to verify the 
volumes of ethanol blended into gasoline under this alternative, the 
IRS forms would not provide useful information related to biodiesel or 
other renewable fuels that are blended into conventional gasoline

[[Page 55594]]

or diesel.\36\ Alternative approaches to verifying that these other 
renewable fuels were actually blended would therefore need to be 
designed under this alternative, and these verifications would 
necessarily involve additional recordkeeping and reporting 
requirements.
---------------------------------------------------------------------------

    \36\ There is some evidence that biodiesel producers are 
operating as blenders in order to claim the right to the Federal 
excise tax credit for biodiesel. However, in these cases they often 
blend only very small amounts of conventional diesel into biodiesel, 
such as 0.1 volume percent. The mixture, identified as B99.9, is 
then transported to another blender who often adds significant 
additional quantities of conventional diesel to make blends such as 
B2 or B20.
---------------------------------------------------------------------------

    This approach would also tend to increase the burdens on refiners 
to gain access to credits and thus demonstrate compliance. A refiner 
who took ownership of a batch of renewable fuel could not use that 
batch to meet its RVO unless he blended it into gasoline or diesel 
himself. Such circumstances would create additional complexity for the 
obligated parties that are avoided by the more streamlined approach we 
are proposing.
    A blender approach would also be difficult to implement. To begin 
with, many blenders are small businesses, and none have been 
substantially regulated in an EPA fuel program before. We would be 
imposing upon these parties the primary enforcement burden associated 
with the RFS program even though they are not obligated for meeting the 
renewable fuel standard. Also, this approach would not be able to 
distinguish between cellulosic biomass ethanol and ethanol made from 
other feedstocks, which creates significant difficulties in meeting 
program requirements.
    Under a blender approach, even accurate records of blending would 
be difficult to verify. There are more than 1200 blenders in the U.S. 
who blend ethanol into gasoline, in addition to those that blend 
biodiesel into conventional diesel fuel. Thus the blender approach 
would maximize the number of parties involved, overly complicating the 
compliance system. The enforcement burden on the Agency would be 
significant, and ultimately it would be likely that many claims of 
blending would go unchecked.
    Some of the concerns raised above could be addressed by re-
introducing the RIN concept into a blender approach. For instance, the 
existence of RINs could help identify cellulosic biomass ethanol as 
such. However, if a RIN-based system were implemented, this alternative 
approach would become very similar to our proposed program, but with 
additional enforcement burdens placed upon blenders. As a result the 
advantages of this alternative approach over our proposed program would 
disappear.
    Due to the additional and unnecessary recordkeeping and reporting 
burdens that would be placed upon blenders under this alternative, the 
dissociation of credits from renewable fuels acquired by obligated 
partiers, and the likelihood that many blending events may go 
unchecked, we do not believe that the alternative blender approach 
should be adopted.

IV. Registration, Recordkeeping, and Reporting Requirements

A. Introduction

    Registration, recordkeeping and reporting are necessary to track 
compliance with the renewable fuels standard and transactions involving 
RINs. We are proposing to utilize the same basic forms for registration 
that we use under the reformulated gasoline (RFG) and anti-dumping 
program.\37\ These forms are well known in the regulated community and 
are simple to fill out. Information requested includes company and 
facility names and addresses and the identification of a contact person 
with phone number and e-mail address. Registrations do not expire and 
upon receipt of a completed registration form, EPA will issue unique 
company and facility identification numbers that will appear in 
compliance reports and, in the case of renewable fuels producers, will 
be incorporated in the unique RINs they generate for each batch of 
renewable fuel. We intend to use the same simplified registration 
method we use for existing fuels programs under 40 CFR part 80, and 
parties who have already registered with EPA under an existing fuels 
program will not be required to re-register and will be able to use 
their existing EPA-issued company and facility registration numbers.
---------------------------------------------------------------------------

    \37\ Please refer to http://www.epa.gov/otaq/regs/fuels/rfgforms.htm. The relevant registration forms for our existing fuels 
programs are 3520-20A, 3520-20B, and 3520-20B1. Interested parties 
may wish to view these forms, as they may be useful in preparing 
comments on this proposed rule.
---------------------------------------------------------------------------

    We plan to use a simplified method of reporting via the Agency's 
Central Data Exchange (CDX). CDX will permit us to accept reports that 
are electronically signed and certified by the submitter in a secure 
and robustly encrypted fashion. Guidance for reporting will be issued 
prior to implementation and will contain specific instructions and 
formats consistent with provisions in the final rule. We intend to 
accept electronic reports generated in virtually all commercially 
available spreadsheet programs and to permit parties to submit reports 
in comma delimited text, which can be generated with a variety of basic 
software packages. In order to permit maximum flexibility in meeting 
the RFS program requirements, we must track activities involving the 
creation and use of RINs, as well as any transactions such as purchase 
or sale of RINs. Reports will be included in a compliance database 
managed by EPA's Office of Transportation and Air Quality and will be 
reviewed for completeness and for potential violations. Potential 
violations will be referred to enforcement personnel.
    Records related to RIN transactions may be kept in any format and 
the period of record retention by reporting parties is five (5) years, 
which is the time frame for retention under similar 40 CFR part 80 
fuels compliance reporting programs. Records retained would include 
copies of all compliance reports submitted to EPA and copies of product 
transfer documents (PTDs). Records would have to be provided to the 
Administrator or the Administrator's representative upon request and 
they may have to be converted to a readable, usable format.

B. Requirements for Obligated Parties and Exporters of Renewable Fuels

1. Registration
    We are proposing that ``obligated parties'' including refiners, 
importers, and blenders of gasoline, as well as exporters of renewable 
fuel, must register with EPA by [90 DAYS AFTER FINAL PUBLICATION OF THE 
FINAL RULE]. Most refiners and importers are already registered with us 
under various regulations related to reformulated (RFG) and 
conventional gasoline or diesel fuel. We propose that these existing 
registrations be applicable under the renewable fuel standard as well. 
Exporters of renewable fuels may not have registered with EPA and we 
anticipate perhaps 25 new registrations and 25 updated registrations 
because of this program. If a party becomes subject to this proposed 
regulation after the effective date, then we propose that they must 
register with us and receive their EPA-issued company and facility 
registration numbers prior to engaging in any transaction involving 
RINs.
    Any party who is not currently registered with us would have to 
submit a simple registration form. We will issue a 4-digit company 
identification number and, for each facility registered, a 5-digit 
facility identification number. Currently registered parties will only 
be

[[Page 55595]]

responsible for updating company and facility records as the need to 
update routine information arises, for example, if corporate points of 
contact or addresses change. Currently registered refiners and 
importers would continue to use their existing 4-digit company and 5-
digit facility identification numbers.
2. Reporting
    There are three types of reports that would be required of 
obligated parties and exporters of renewable fuel. Reports would be 
required to be submitted on an annual basis by the February 28 
following a given January through December annual compliance period.
    The first type of report would provide the compliance 
demonstration. It would require obligated parties to provide 
information about their annual volume of gasoline produced or imported, 
and would require exporters to provide information about their annual 
volume of renewable fuel exported. The report would also describe the 
calculation of their corresponding renewable volume obligation (RVO), a 
listing of the RINs applied towards the RVO, any deficit carried over 
from the previous year, and any deficit carried into the next year.
    The second type of report would provide detailed transactional 
information regarding RINs. It would be akin to credit trading reports 
submitted by refiners and importers under other fuels programs in 40 
CFR part 80, such as the gasoline sulfur program. The purpose of this 
report would be to document the ownership, transfer and use of RINs and 
to track expired RINs. As such, and noted below, these reports would be 
required of any party that owns RINs during the compliance period 
covered by the report. The transactional report is necessary because 
compliance with the RVO is primarily demonstrated through self-
reporting of RIN trades and therefore it is necessary for Agency 
personnel to be able to link transactions involving each unique RIN in 
order to verify compliance. We will be able to import reports into our 
compliance database and match RINs to transactions across their entire 
journey from generation to use. As with our other 40 CFR part 80 
compliance-on-average and credit trading programs, many potential 
violations are expected to be self-reported. Because the use of RINs 
permits great flexibility in meeting the RVO, we believe that obligated 
parties and others who create and handle RINs (including brokers) will 
benefit from self-reporting.
    The third type of report will summarize RIN activities for the 
previous year and will include the total number of RINs owned, used for 
compliance, transferred and expired. This report would not include 
details of every RIN owned or used, since this information would be 
included in the compliance and transactional reports. Instead, this 
third report would simply summarize the total number of RINs falling 
into different categories.
    All reports submitted to us would have to be signed and certified 
as true and correct by a responsible corporate officer. This can be 
done electronically. As discussed above, we plan to utilize a highly 
simplified electronic method of reporting via the Agency's Central Data 
Exchange that is secure, provides encryption and reliable electronic 
signatures, and that permits us to accept reports in the submitter's 
choice of simple comma delimited text or commercially available 
spreadsheet packages.
    We are proposing annual reporting only. However, we encourage 
comments related to the frequency of reporting. We are particularly 
interested in comments related to the frequency of transactional 
reports related to RINs and whether these reports should be submitted 
quarterly rather than annually. We also request comment on our proposed 
requirement that three distinct types of reports be submitted for each 
calendar year, specifically whether these reports could be simplified 
or whether a smaller number of reports could provide the same 
information.
3. Recordkeeping
    The proposed recordkeeping requirements for obligated parties and 
exporters of renewable fuel support the enforcement of the use of RINs 
for compliance purposes. Product transfer documents (PTDs) are central 
to tracking individual RINs through the fungible distribution system 
when those RINs are assigned to batches of renewable fuel. PTDs are 
customarily issued in the course of business (i.e., issuing them is a 
``customary business practice'') and are familiar to parties who 
transfer or receive fuel. As with other fuels programs, PTDs may take 
many forms, including bills of lading, as long as they travel with the 
volume of renewable fuel being transferred. Specifically, we propose 
that on each occasion any person transfers ownership of renewable fuels 
subject to this proposed regulation that they provide the transferee 
documents identifying the renewable fuel and containing identifying 
information including the name and address of the transferor and 
transferee, the EPA-issued company and facility IDs of the transferor 
and transferee, the volume of renewable fuel that is being transferred, 
the location of the renewable fuel at the time of transfer, and the 
unique RIN associated with the volume of fuel being transferred, if 
any. PTDs are used by all parties in the distribution chain down to the 
retail outlet or wholesale purchaser-consumer facility that dispenses 
it into motor vehicles.
    Except for transfers to truck carriers, retailers or wholesale 
purchaser-consumers, product codes describing various attributes of the 
fuel may be used to convey the information required for PTDs, as long 
as the codes are clearly understood by each transferee. Therefore, 
refiners and importers and exporters of renewable fuel may use codes. 
The RIN would always have to appear on each PTD in its entirety before 
it is separated from a batch, since it is a unique identification 
number and cannot be summarized by a shorter code.
    Obligated parties and exporters of renewable fuel would have to 
keep copies of PTDs and of all compliance reports submitted to EPA for 
a period of not less than five (5) years. The five year period is 
common to all our 40 CFR part 80 programs and is a reasonable period to 
retain records in the event a potential violation is reported and must 
be investigated and pursued by enforcement personnel. They would also 
have to keep information related to the sale, purchase, brokering and 
trading of RINs that support the information they report to EPA. 
Refiners and importers would be responsible for providing records to 
the Administrator or the Administrator's authorized representative in a 
usable format upon request.

C. Requirements for Producers and Importers of Renewable Fuel

1. Registration
    We propose that any producer or importer of renewable fuel must 
register by [90 DAYS AFTER THE DATE OF FINAL PUBLICATION OF THE FINAL 
RULE]. The registration requirements are the same as those for refiners 
and importers of gasoline, as described above. Renewable fuel producers 
were not previously required to register with EPA and we anticipate 
around 280 new registrants as a result of this proposed registration 
requirement. Although renewable fuels producers are not ``obligated 
parties,'' they are the parties who generate RINs. As mentioned above 
in IV.B.1, the EPA-issued registration numbers will be part of the 
unique RIN generated by the producer or importer of renewable fuel. In 
order to support effective recordkeeping and reporting

[[Page 55596]]

for compliance purposes, we believe it is necessary for them and any 
party who generates or owns RINs to register with the Agency.
    Registration is a simple process and there is no expiration date 
associated with a registration. However, registration information may 
be updated by the registrant as needed, for example, if a mailing 
address changes. The information collected includes company name and 
address; facility name(s) and address(es); and a contact person's name, 
phone number and e-mail address. Any party who is not currently 
registered with us would have to submit registration forms. We will 
issue a 4-digit company identification number and, for each facility 
registered, a 5-digit facility identification number. If a party 
becomes subject to this proposed regulation after the effective date, 
then we propose that they must register with us and receive their EPA-
issued company and facility identification numbers prior to generating 
or holding any RINs.
    We also propose that small volume domestic producers of renewable 
fuels, those who produce less than 10,000 gallons per year, be allowed 
to remain unregistered. This proposed provision would free them from 
recordkeeping and reporting requirements, but it would also preclude 
them from generating RINs.
2. Reporting
    Renewable fuel producers and importers would be required to submit 
three different annual reports by February 28, reflecting activity 
during the previous calendar year. The first report would be an annual 
report that reflects the generation of RINs. This report would identify 
each batch of renewable fuel produced or imported during the previous 
year and the RINs generated for each batch. This annual report would 
provide information about the production date, renewable fuel type and 
volume of renewable fuel produced or imported. For specific information 
about how RINs are actually generated, please refer to the discussion 
in Section III.D.2 of this preamble.
    Like any of the parties who can own RINs, a renewable fuel producer 
would also have to submit a second type of report detailing 
transactional information regarding RINs. This report would list the 
RINs which they own at the end of the reporting period as well as any 
RINs they have acquired from other parties or have transferred to other 
parties, identifying which parties took part in the transfer. This 
report would be similar to the transaction report described below 
required of RIN owners who are not obligated parties, exporters, or 
producers of renewable fuels.
    Finally, each producer or importer of renewable fuel would be 
required to submit a third annual report summarizing RIN activities for 
the previous year. This report would include the total number of RINs 
generated, owned, transferred, and expired.
    All reports would have to be signed and certified as true and 
correct by a responsible corporate officer. This can be done 
electronically. As discussed above, we plan to utilize a highly 
simplified electronic method of reporting via the Agency's Central Data 
Exchange that is secure, provides encryption and reliable electronic 
signatures, and that permits generation of reports in the submitter's 
choice of simple comma delimited text or commercially available 
spreadsheet packages.
    We request comment on our proposed requirement that three distinct 
types of reports be submitted for each calendar year, specifically 
whether these reports could be simplified or whether a smaller number 
of reports could provide the same information.
3. Recordkeeping
    The proposed recordkeeping requirements for renewable fuels 
producers support the enforcement of the use of RINs for compliance 
purposes. Product transfer documents (PTDs) are central to tracking 
individual RINs through the fungible distribution system when those 
RINs are assigned to batches of renewable fuel. PTDs are customarily 
generated and issued in the course of business (i.e. issuing them is a 
``customary business practice'') and are familiar to parties who 
transfer or receive fuel. As with other fuels programs, PTDs may take 
many forms, including bills of lading, as long as they travel with the 
volume of renewable fuel being transferred. Specifically, we propose 
that on each occasion any person transfers ownership of renewable fuels 
subject to this proposed regulation that they provide the transferee 
documents identifying the renewable fuel and containing identifying 
information including the name and address of the transferor and 
transferee, the EPA-issued company and facility IDs of the transferor 
and transferee, the volume of renewable fuel that is being transferred, 
the location of the renewable fuel at the time of transfer, and the 
unique RIN associated with the volume of fuel being transferred, if 
any. PTDs are used by all parties in the distribution chain down to the 
retail outlet or wholesale purchaser-consumer facility that dispenses 
it into motor vehicles.
    Except for transfers to truck carriers, retailers or wholesale 
purchaser-consumers, product codes may be used to convey the 
information required for PTDs, as long as the codes are clearly 
understood by each transferee. Therefore, renewable fuels producers may 
use codes. The RIN would always have to appear on each PTD in its 
entirety before it was separated from the batch, since it is a unique 
identification number and cannot be summarized by a shorter code.
    Renewable fuels producers would have to keep copies of PTDs and of 
all compliance reports submitted to EPA for a period of not less than 
five (5) years. They would also have to keep information related to the 
sale, purchase, brokering and trading of RINs. Upon request, renewable 
fuels producers or importers would be responsible for providing 
documentation of PTDs to the Administrator or the Administrator's 
authorized representative in a usable format.

D. Requirements for Other Parties Who Own RINs

1. Registration
    We propose that other parties who intend to own RINs, and who are 
not obligated parties, exporters of renewable fuels, or renewable fuels 
producers or importers, must also register before ownership of any RINs 
is assumed. The registration requirements are the same as those for 
other parties discussed previously in Sections IV.B.1 and IV.C.1 above, 
and require the registrant to provide very basic information about the 
company, its facility or facilities, and a contact person. The 
registration is on very simple forms provided by EPA. A variety of 
parties may own RINs including (but certainly not limited to) 
marketers, blenders, terminal operators, and jobbers. (As is mentioned 
in the previous two sections, obligated parties and renewable producers 
may also own RINs but have other reporting responsibilities, as well.)
    It is possible to own RINs separately from batches of renewable 
fuel. For example, a broker might be expected to own RINs in this 
fashion. Any party who is not currently registered with us and who 
intends to own RINs would have to submit a simple registration form, as 
described above. We anticipate about 1,500 new registrants as a result 
of this proposed registration requirement, although an exact estimation 
of the number of parties that will constitute this group is difficult 
to

[[Page 55597]]

make. As with the other parties described in this Section, we will 
issue a 4-digit company identification number and, for each facility 
registered, a 5-digit facility identification number. If a party 
becomes subject to this proposed regulation after the effective date, 
then we propose that they must register with us and receive their EPA-
issued company and facility identification numbers prior to owning any 
RINs.
2. Reporting
    Parties who own RINs would be required to submit two types of 
annual reports by February 28, representing activity in the previous 
calendar year. The first report would document RIN transactions. This 
report is akin to the credit trading reports submitted by refiners and 
importers under other fuels programs in 40 CFR part 80 and is the same 
as the second report described for obligated parties in some detail in 
Section IV.B.2 above.
    The second type of report would summarize RIN activities for the 
previous year, including the total number of RINs owned, transferred, 
and expired. This report would not include details of every RIN owned 
or used, since this information would be included in the transactional 
report. Instead, this report would simply summarize the total number of 
RINs falling into different categories.
    All reports would have to be signed and certified as true and 
correct by a responsible corporate officer. This can be done 
electronically. As discussed above, we plan to utilize a highly 
simplified electronic method of reporting via the Agency's Central 
Data.
    As discussed above, we are seeking comments on the frequency of 
reporting, especially with regard to RIN transactions. We are proposing 
annual reporting, but are seeking comments on whether reporting should 
be quarterly.
    We also request comment on our proposed requirement that two 
distinct types of reports be submitted for each calendar year, 
specifically whether these reports could be simplified or whether a 
smaller number of reports could provide the same information.
3. Recordkeeping
    The proposed recordkeeping requirements for parties who own RINs 
support the enforcement of the use of RINs for compliance purposes. 
Product transfer documents (PTDs) are central to tracking individual 
RINs through the fungible distribution system when those RINs are 
assigned to batches of renewable fuel. PTDs are customarily generated 
and issued in the course of business (i.e., issuing them is a 
``customary business practice'') and are familiar to parties who 
transfer or receive fuel. As with other fuels programs, PTDs may take 
many forms, including bills of lading, as long as they travel with the 
volume of renewable fuel being transferred. Specifically, we propose 
that on each occasion any person transfers ownership of RINs (whether 
assigned to batches of renewable fuel or not) that they provide the 
transferee documents identifying the RIN and containing identifying 
information including the name and address of the transferor and 
transferee, the EPA-issued company and facility IDs of the transferor 
and transferee, and the unique RINs that are being transferred. 
Typically, parties who own RINs connected with batches of fuel would 
handle PTDs; however, parties who own RINs separate from batches may 
not. A party who owns RINs in connection with fuel and who received a 
PTD would be responsible for meeting requirements related to PTDs.
    Parties who own RINs but who are not obligated parties, exporters 
of renewable fuel, or renewable fuel producers or importers would have 
to keep copies of PTDs associated with RIN transfers and of all 
compliance reports submitted to EPA for a period of not less than five 
(5) years. They would also have to keep information related to the 
sale, purchase, brokering and trading of RINs. Upon request, owners of 
RINs would be responsible for providing records to the Administrator or 
the Administrator's authorized representative in a usable format.

V. What Acts Are Prohibited and Who Is Liable for Violations?

    The prohibition and liability provisions applicable to this 
proposed RFS program would be similar to those of other gasoline 
programs. The proposed rule identifies certain prohibited acts, such as 
a failure to acquire sufficient RINs to meet a party's renewable fuel 
obligation (RVO), producing or importing a renewable fuel that is not 
assigned a proper RIN, creating or transferring invalid RINs, or 
transferring RINs that are not identified by proper RIN numbers. Any 
person subject to a prohibition would be held liable for violating that 
prohibition. Thus, for example, an obligated party would be liable if 
the party failed to acquire sufficient RINs to meet its RVO. A party 
who produces or imports renewable fuels would be liable for a failure 
to assign proper RINs to batches of renewable fuel produced or 
imported. Any party, including an obligated party, would be liable for 
transferring a RIN that was not properly identified.
    In addition, any person who is subject to an affirmative 
requirement under the RFS program would be liable for a failure to 
comply with the requirement. For example, an obligated party would be 
liable for a failure to comply with the annual compliance reporting 
requirements. A renewable fuel producer or importer would be liable for 
a failure to comply with the applicable batch reporting requirements. 
Any party subject to recordkeeping or product transfer document 
requirements would be liable for a failure to comply with these 
requirements. Like other EPA fuels programs, the proposed rule provides 
that a party who causes another party to violate a prohibition or fail 
to comply with a requirement may be found liable for the violation.
    The Energy Act amended the penalty and injunction provisions in 
section 211(d) of the Clean Air Act to apply to violations of the 
renewable fuels requirements in section 211(o).\38\ Accordingly, under 
the proposed rule, any person who violates any prohibition or 
requirement of the RFS program may be subject to civil penalties for 
every day of each such violation and the amount of economic benefit or 
savings resulting from the violation. Under the proposed rule, a 
failure to acquire sufficient RINs to meet a party's renewable fuels 
obligation would constitute a separate day of violation for each day 
the violation occurred during the annual averaging period.
---------------------------------------------------------------------------

    \38\ Sec. 1501(b) of the Energy Policy Act of 2005.
---------------------------------------------------------------------------

    As discussed above and in Section III.D, the regulations would 
prohibit any party from creating or transferring invalid RINs. These 
invalid RIN provisions would apply regardless of the good faith belief 
of a party that the RINs were valid. These enforcement provisions are 
necessary to ensure the RFS program goals are not compromised by 
illegal conduct in the creation and transfer of RINs.
    As in other motor vehicle fuel credit programs, the regulations 
would address the consequences if an obligated party was found to have 
used invalid RINs to demonstrate compliance with its RVO. In this 
situation, the refiner or importer that used the invalid RINs would be 
required to deduct any invalid RINs from its compliance calculations. 
The refiner or importer would be liable for violating the standard if 
the remaining number of valid RINs was insufficient to meet its RVO, 
and the obligated party might be subject to monetary penalties if it 
used invalid RINs in its compliance demonstration. In determining what 
penalty is appropriate, if any, we would consider a number of factors, 
including

[[Page 55598]]

whether the obligated party did in fact procure sufficient valid RINs 
to cover the deficit created by the invalid RINs, and whether the 
purchaser was indeed a good faith purchaser based on an investigation 
of the RIN transfer. A penalty might include both the economic benefit 
of using invalid RINs and/or a gravity component.
    Although an obligated party would be liable under our proposed 
program for a violation if it used invalid RINs for compliance 
purposes, we would normally look first to the generator or seller of 
the invalid RINs both for payment of penalty and to procure sufficient 
valid RINs to offset the invalid RINs. However, if, for example, that 
party was out of business, then attention would turn to the obligated 
party who would have to obtain sufficient valid RINs to offset the 
invalid RINs.
    Because there are no standards under the RFS rule that may be 
measured downstream, we believe that a presumptive liability scheme, 
i.e., a scheme in which parties upstream from the facility where the 
violation is found are presumed liable for the violation, would not be 
applicable under the RFS program. We request comment on whether a 
presumptive liability scheme may have application under the RFS rule. 
We also request comment on the need for additional prohibition and 
liability provisions specific to the proposed RFS program.

VI. Current and Projected Renewable Fuel Production and Use

    While the definition of renewable fuel does not limit compliance 
with the standard to any one particular type of renewable fuel, ethanol 
is currently the most prevalent renewable fuel blended into gasoline 
today. Biodiesel represents another renewable fuel, which while not as 
widespread as ethanol use (in terms of volume), has been increasing in 
production capacity and use over the last several years. This section 
provides a brief overview of the ethanol and biodiesel industries today 
and how they are projected to grow into the future.

A. Overview of U.S. Ethanol Industry and Future Production/Consumption

1. Current Ethanol Production
    As of June 2006, there were 102 ethanol production facilities 
operating in the United States with a combined production capacity of 
approximately 4.9 billion gallons per year.\39\ All of the ethanol 
currently produced comes from grain or starch-based feedstocks that can 
easily be broken down into ethanol via traditional fermentation 
processes. The majority of ethanol (almost 93 percent by volume) is 
produced exclusively from corn. Another 7 percent comes from a blend of 
corn and/or similarly processed grains (milo, wheat, or barley) and 
less than 1 percent is produced from waste beverages, cheese whey, and 
sugars/starches combined. A summary of ethanol production by feedstock 
is presented in Table VI.A.1-1.
---------------------------------------------------------------------------

    \39\ The June 2006 ethanol production baseline was generated 
from a variety of data sources including Renewable Fuels Association 
(RFA), Ethanol Biorefinery Locations (Updated June 19, 2006); 
Ethanol Producer Magazine (EPM), U.S. & Canada Fuel Ethanol Plant 
Map (Spring 2006); and International Fuel Quality Center (IFQC), 
Special Biofuels Report <greek-i>75 (April 11, 2006) as well as 
ethanol producer websites. The production baseline includes small-
scale ethanol production facilities as well as former food-grade 
ethanol plants that have since transitioned into the fuel-grade 
ethanol market. Where applicable, current ethanol plant production 
levels were used to represent plant capacity, as nameplate 
capacities are often underestimated.

b Includes brewery waste.

    There are a total of 94 plants processing corn and/or other 
similarly processed grains. Of these facilities, 84 utilize dry milling 
technologies and the remaining 10 plants rely on wet-milling processes. 
Dry mill ethanol plants grind the entire kernel and produce only one 
primary co-product: distillers' grains with solubles (DGS). The co-
product is sold wet (WDGS) or dried (DDGS) to the agricultural market 
as animal feed. Carbon dioxide is also produced in the process and may 
be recovered as a saleable product. In contrast to dry mill plants, wet 
mill facilities separate the kernel prior to processing and in turn 
produce other co-products (usually gluten feed, gluten meal, and oil) 
in addition to DGS. Wet mill plants are generally more costly to build 
but are larger in size on average. As such, approximately 23 percent of 
the current ethanol production comes from the 10 previously-mentioned 
wet mill facilities.
    The remaining 8 plants which process waste beverages, cheese whey, 
or sugars/starches, operate differently than their grain-based 
counterparts. These facilities do not require milling and instead 
operate a more simplistic enzymatic fermentation process.
    In addition to grain and starch-to-ethanol production, another 
method exists for producing ethanol from a more diverse feedstock base. 
This process involves converting cellulosic feedstocks such as bagasse, 
wood, straw, switchgrass, and other biomass into ethanol. Cellulose 
consists of tightly-linked polymers of starch, and production of 
ethanol from it requires additional steps to convert these polymers 
into fermentable sugars. Scientists are actively pursuing acid and 
enzyme hydrolysis to achieve this goal, but the technologies are still 
not fully developed for large-scale commercial production. As of June 
2006, there were no U.S ethanol plants processing cellulosic 
feedstocks. Currently, the only known cellulose-to-ethanol plant in 
North America is Iogen in Canada, which produces approximately one

[[Page 55599]]

million gallons of ethanol per year from wood chips. For a more 
detailed discussion on cellulosic ethanol production/technologies, 
refer to Section 7.1.2 of the Draft Regulatory Impact Analysis (DRIA).
    The ethanol production process is relatively resource-intensive and 
requires the use of water, electricity and steam. Steam needed to heat 
the process is generally produced onsite or by other dedicated boilers. 
Of today's 102 ethanol production facilities, 98 burn natural gas, 2 
burn coal, 1 burns coal and biomass, and 1 burns syrup from the process 
to produce steam. A summary of ethanol production by plant energy 
source is found below in Table VI.A.1-2.

\a\ Includes a natural gas facility which is considering transitioning to coal.

    Currently, 7 of the 102 ethanol plants utilize co-generation or 
combined heat and power (CHP) technology. CHP is a mechanism for 
improving overall plant efficiency. CHP facilities produce their own 
electricity (or coordinate with the local municipality) and use 
otherwise-wasted exhaust gases to help heat their process, reducing the 
overall demand for boiler fuel.
    The majority of ethanol is produced in the Midwest within PADD 2--
not surprisingly, where most of the corn is grown. Of the 102 U.S. 
ethanol production facilities, 93 are located in Midwest. The PADD 2 
facilities account for about 97 percent (or 4.7 billion gallons per 
year) of the total domestic ethanol production, as shown in Table 
VI.A.1-3.

    Leading the Midwest in ethanol production are Iowa, Illinois, 
Nebraska, Minnesota, and South Dakota with a combined capacity of 3.9 
billion gallons per year. Together, these five states' 69 ethanol 
plants account for 80 percent of the total domestic product. Although 
the majority of ethanol production comes from the Midwest, there is a 
sprinkling of plants situated outside the corn belt ranging from 
California to Tennessee all the way down to Georgia.
    The U.S. ethanol industry is currently comprised of a mixture of 
corporations and farmer-owned cooperatives (co-ops). More than half 
(55) of today's plants are owned by corporations and, on average, these 
plants are larger in size than farmer-owned co-ops. Accordingly, 
company-owned plants account for nearly 65 percent of the total U.S. 
ethanol production capacity. Additionally, 45 percent of the total 
capacity comes from 22 plants owned by just 8 different companies.
2. Expected Growth in Ethanol Production
    Over the past 25 years, domestic fuel ethanol production has 
steadily increased due to technological advances, environmental 
regulation (e.g., oxygenate requirements in ozone and carbon monoxide 
non-attainment areas), and the rising cost of crude oil. More recently, 
ethanol production has soared due to state MTBE bans, steep increases 
in crude oil prices, and producer tax incentives. As shown below in 
Figure VI.A.2-1, over the past three years, domestic ethanol production 
has nearly doubled from 2.1 billion gallons in 2002 to 4.0 billion 
gallons in 2005.

[[Page 55600]]

[GRAPHIC] [TIFF OMITTED] TP22SE06.002

    EPA forecasts ethanol production to continue to grow into the 
future. In addition to the past impacts of Federal and state tax 
incentives, as well as the more recent impacts of state ethanol 
mandates and the removal of MTBE from all U.S. gasoline, record-high 
crude oil prices are expected to continue to drive up demand for 
ethanol. As a result, the nation is on track to exceed the renewable 
fuel volume requirements contained in the Act. Today's ethanol 
production capacity (4.9 billion gallons) is already exceeding the 2006 
renewable fuel requirement (4.0 billion gallons). In addition, there is 
another 2.5 billion gallons of ethanol production capacity currently 
under construction.\40\ A summary of the new construction and expansion 
projects currently underway (as of June 2006) is found in Table VI.A.2-

\a\ Under Construction.

    A select group of builders, technology providers, and construction 
contractors are completing the majority of the construction projects 
described in Table VI.A.2-1. As such, the completion dates of these 
projects are staggered over approximately 18 months, resulting in the 
gradual phase-in of ethanol production shown in Figure VI.A.2-2.
[GRAPHIC] [TIFF OMITTED] TP22SE06.003

    As shown in Table VI.A.2-1 and Figure VI.A.2-2, once all the 
construction projects currently underway are complete (estimated by 
December 2007), the resulting U.S. ethanol production capacity would be 
over 7.3 billion gallons. Together with estimated biodiesel production 
(300 million gallons by 2012), this would be more than enough renewable 
fuel to satisfy the 2012 renewable fuel requirement (7.5 billion 
gallons) contained in the Act. However, ethanol production is not 
expected to stop here. There are more and more ethanol projects being 
announced each day. Many of these potential projects are at various 
stages of planning, such as conducting feasibility studies, gaining 
city/county approval, applying for permits, applying for financing/
fundraising, or obtaining contractor agreements. Other projects have 
been proposed or announced, but have not entered the formal planning 
process. If all these plants were to come to fruition, the combined 
domestic ethanol production could exceed 20 billion gallons as shown in 
Table VI.A.2-2.

\a\ Under Construction.

    However, although there is clearly a great potential for growth in 
ethanol production, it is unlikely that all the announced projects 
would actually reach completion in a reasonable amount of time. There 
is no precise way to know exactly which plants would come to fruition 
in the future; however, we've chosen to focus our further discussions 
on only those plants which are under construction or in the final 
planning stages (denoted as ``planned'' above in Table VI.A.2-2). The 
distinction between ``planned'' versus ``proposed'' is that as of June 
2006 planned projects had completed permitting, fundraising/financing, 
and had builders assigned with definitive construction timelines 
whereas proposed projects did not.
    As shown in Table VI.A.2-2, once all the under construction and 
planned projects are complete (by 2012 or sooner), the resulting U.S. 
ethanol production capacity would be 9.8 billion gallons, exceeding the 
2012 EIA demand estimate (9.6 billion gallons). This forecasted growth 
would double today's production capacity and greatly exceed the 2012 
renewable fuel requirement (7.5 billion gallons). In addition, domestic 
ethanol production would be supplemented by imports, which are also 
expected to increase in the future (as discussed in DRIA Section 1.5).
    Of the 60 forecasted new ethanol plants (39 under construction and 
21 planned), all would (at least initially) rely on grain-based 
feedstocks. Of the plants, 56 would rely exclusively on corn as a 
feedstock. As for the remaining plants: Two would rely on both corn and 
milo, one would process molasses and sweet sorghum, and the last would 
start off processing corn and then transition into processing bagasse, 
rice hulls, and wood.
    Under the Energy Act, the RFS program requires that 250 million 
gallons of the renewable fuel consumed in 2013 and beyond meet the 
definition of cellulosic biomass ethanol. As discussed in Section 
III.B.1, the Act defines cellulosic biomass ethanol as ethanol derived 
from any lignocellulosic or hemicellulosic matter that is available on 
a renewable or recurring basis including dedicated energy crops and 
trees, wood and wood residues, plants, grasses, agricultural residues, 
fibers, animal wastes and other waste materials, and municipal solid 
waste. The term also includes any ethanol produced in facilities where 
animal or other waste materials are digested or otherwise used to 
displace 90 percent of more of the fossil fuel normally used in the 
production of ethanol.
    Of the 60 forecasted plants, only one is expected to meet the 
definition of ``cellulosic biomass ethanol'' based on feedstocks. The 
planned 108 MMgal/yr facility would start off processing corn and then 
transition into processing bagasse, rice hulls, and wood (cellulosic 
feedstocks). It is unclear as to whether this facility would be 
processing cellulosic material by 2013, however there are several other 
facilities that could potentially meet the Act's definition of 
cellulosic ethanol based on plant energy sources. In total, there are 
seven ethanol plants that burn or plan to burn renewable feedstocks to 
generate steam for their processes. As shown in Table VI.A.1-2, two 
existing plants burn renewable feedstocks. One plant burns a 
combination of coal and biomass and the other burns syrup from the 
production process. Together these existing plants have a combined 
ethanol production capacity of 99 MMgal/yr. Additionally, there are 
four under construction ethanol plants which plan to burn renewable 
fuels. One plant plans to burn a combination of coal and biomass, two 
plants plan to rely on manure/syngas, and the other plans to start up 
burning natural gas and then transition to biomass. Together these 
under construction facilities have a combined ethanol production 
capacity of 87 MMgal/yr. Finally, a planned 275 MMgal/yr ethanol 
production facility plans to burn a combination of coal, tires, and 
biomass. Depending on how much fossil fuel is displaced by these 
renewable feedstocks (on a plant-by-plant basis), a portion or all of 
the aforementioned ethanol production (up to 461 MMgal/yr) could 
potentially qualify as ``cellulosic biomass ethanol'' under the Act. 
Combined with the 108 MMgal/yr plant planning to process renewable 
feedstocks, the total cellulosic potential could be as high as 569 
MMgal/yr in 2013. Even if only half of this ethanol were to end up 
qualifying as cellulosic biomass ethanol, it would still be more than 
enough to satisfy the Act's cellulosic requirement (250 million 
gallons).\41\
---------------------------------------------------------------------------

    \41\ We anticipate a ramp-up in cellulosic ethanol production in 
the years to come so that capacity exists to satisfy the 2013 Act's 
requirement (250 million gallons of cellulosic biomass ethanol). 
Therefore, for subsequent analysis purposes, we have assumed that 
250 million gallons of ethanol would come from cellulosic biomass 
sources by 2012.
---------------------------------------------------------------------------

3. Current Ethanol and MTBE Consumption
    To understand the impact of the increased ethanol production/use on 
gasoline properties and in turn overall air quality, we first need to 
gain a better understanding of where ethanol is used today and how the 
picture is going to change in the future. As such, in addition to the 
production analysis presented above, we have completed a parallel 
consumption analysis comparing current ethanol consumption to future 
predictions.
    In the 2004 base case, 3.5 billion gallons of ethanol \42\ and 1.9 
billion gallons of MTBE \43\ were blended into gasoline to supply the 
transportation sector with a total of 136 billion gallons of 
gasoline.\44\ A breakdown of the 2004 gasoline and oxygenate 
consumption by PADD is found below in Table VI. A.3-1.

\a\ MTBE blended into RFG.
\b\ PADD 5 excluding California.

    As shown above, nearly half (or about 45 percent) of the ethanol 
was consumed in PADD 2 gasoline, not surprisingly, where the majority 
of ethanol was produced. The next highest region of use was the State 
of California which accounted for about 25 percent of domestic ethanol 
consumption. This is reasonable because California alone accounts for 
over 10 percent of the nation's total gasoline consumption and all the 
fuel (both Federal RFG and California Phase 3 RFG) has been assumed to 
contain ethanol (following their recent MTBE ban) at 5.7 volume 
percent.\45\ The bulk of the remaining ethanol was used in reformulated 
gasoline (RFG) and winter oxy-fuel areas requiring oxygenated gasoline. 
Overall, 62 percent of ethanol was used in RFG, 33 percent was used in 
CG, and 5 percent was used in winter oxy-fuel.\46\
---------------------------------------------------------------------------

    \45\ Based on conversation with Dean Simeroth at California Air 
Resources Board (CARB).
    \46\ For the purpose of this analysis, except where noted, the 
term pertains to Federal RFG plus California Phase 3 RFG (CaRFG3) 
and Arizona Clean Burning Gasoline (CBG).
---------------------------------------------------------------------------

    As shown above in Table VI.A.3-1, 99 percent of MTBE use occurred 
in PADDs 1 and 3. This reflects the high concentration of RFG areas in 
the northeast (PADD 1) and the local production of MTBE in the gulf 
coast (PADD 3). PADD 1 receives a large portion of its gasoline from 
PADD 3 refineries who either produce the fossil-fuel based oxygenate or 
are closely affiliated with MTBE-producing petrochemical facilities in 
the area. Overall, 100 percent of MTBE in 2004 was assumed to be used 
in reformulated gasoline.\47\
---------------------------------------------------------------------------

    \47\ 2004 MTBE consumption was obtained from EIA. The data 
received was limited to states with RFG programs, thus MTBE use was 
assumed to be limited to RFG areas for the purpose of this analysis.
---------------------------------------------------------------------------

    In 2004, total ethanol use exceeded MTBE use. Ethanol's lead 
oxygenate role is relatively new, however the trend has been a work in 
progress over the past few years. From 2001 to 2004, ethanol 
consumption more than doubled (from 1.7 to 3.5 billion gallons), while 
MTBE use (in RFG) was virtually cut in half (from 3.7 to 1.9 billion 
gallons). A plot of oxygenate use over the past decade is provided 
below in Figure VI.A.3-1.
    The nation's transition to ethanol is linked to states'' responses 
to recent environmental concerns surrounding MTBE groundwater 
contamination. Resulting concerns over drinking water quality have 
prompted several states to significantly restrict or completely ban 
MTBE use in gasoline. At the time of this analysis, 19 states had 
adopted MTBE bans. A list of the states with MTBE bans is provided in 
DRIA Table 2.1-4.

4. Expected Growth in Ethanol Consumption
---------------------------------------------------------------------------

    \48\ Total ethanol use based on EIA Monthly Energy Review, June 
2006 (Table 10.1: Renewable Energy Consumption by Source, Appendix 
A: Thermal Conversion Factors). MTBE use in RFG also provided by EIA 
(file received from EIA representative on March 9, 2006). Reported 
2004 MTBE use has been adjusted from 2.0 to 1.9 Bgal based on 
assumption of timely implementation of CA, CT, and NY MTBE bans on 
1/1/04 (EIA reported a slight delay and thus showed small amounts of 
MTBE use in these states in 2004).
---------------------------------------------------------------------------

    As mentioned above, ethanol demand is expected to increase well 
beyond the levels contained in the renewable fuels standard (RFS) under 
the Act. With the removal of the oxygenate mandate for reformulated 
gasoline (RFG),\49\ all U.S. refiners are expected to eliminate the use 
of MTBE in gasoline as soon as possible. In order to accomplish this 
transition quickly (by 2006 or 2007 at the latest) while maintaining 
gasoline volume, octane, and mobile source air toxics emission 
performance standards, refiners are electing to blend ethanol into 
virtually all of their RFG.\50\ This has caused a dramatic increase in 
demand for ethanol which, in 2006 is being met by temporarily shifting 
large volumes of ethanol out of conventional gasoline and into RFG 
areas. By 2012, however, ethanol production will have grown to 
accommodate the removal of MTBE without the need for such a shift from 
conventional gasoline. More important than the removal of MTBE over the 
long term, however, is the impact that the dramatic rise in the price 
of crude oil is having on demand for renewable fuels, both ethanol and 
biodiesel. This has dramatically improved the economics for renewable 
fuel use, leading to a surge in demand that is expected to continue. In 
the Annual Energy Outlook (AEO) 2006, EIA forecasted that by 2012, 
total ethanol use (corn, cellulosic, and imports) would be about 9.6 
billion gallons \51\ and biodiesel use would be about 0.3 billion 
gallons at a crude oil price forecast of $47 per barrel. This ethanol 
projection was not based on what amount the market would demand (which 
could be higher), but rather on the amount that could be produced by 
2012. Others are making similar predictions, and as discussed above in 
VI.A.2, production capacity would be sufficient. Therefore, in 
assessing the impacts of expanded use of renewable fuels, we have 
chosen to evaluate two different future ethanol consumption levels, one 
reflecting the statutory required minimum, and one reflecting the 
higher levels projected by EIA. For the statutory consumption scenario 
we assumed 7.2 billion gallons of ethanol (0.25 of which was assumed to 
be cellulosic) and 0.3 billion gallons of biodiesel. For the higher 
projected renewable fuel consumption scenario, we assumed 9.6 billion 
gallons of ethanol (0.25 of which is once again assumed to be 
cellulosic) and 0.3 billion gallons of biodiesel. Although the actual 
renewable fuel volumes consumed in 2012 may differ from both the 
required and projected volumes, we believe that these two scenarios 
provide a reasonable range for analysis purposes.\52\

    \51\ AEO 2006 Table 17 Renewable Energy Consumption by Sector 
and Source shows 0.80 quadrillion BTUs of energy coming from ethanol 
in 2012. A parallel spreadsheet provided to EPA shows 2012 total 
ethanol use as 628.7 thousand bbls/day (which works out to be 9.64 
billion gallons/yr).
    \52\ As a comparison point for cost and emissions analyses, a 
2012 reference case of 3.9 billion gallons of ethanol was also 
considered. The reference case is described in Section II.A.1 
(above) and a complete derivation is contained in DRIA Section 
2.1.3.
---------------------------------------------------------------------------

    In addition to modeling two different future 2012 ethanol 
consumption levels, two scenarios were considered based on how 
refineries could potentially respond to the recent removal of the RFG 
oxygenate mandate. In both cases, the impacted RFG areas did not change

[[Page 55605]]

from the 2004 base case.\53\ In the maximum scenario (``max-RFG''), 
refineries would continue to add oxygenate (ethanol) into all batches 
of reformulated gasoline. In this case, refineries currently blending 
MTBE (at 11 volume percent) would be expected to replace it with 
ethanol (at 10 volume percent). In the minimum scenario (``min-RFG''), 
we predict some refineries would respond by using less (or even zero) 
ethanol in RFG based on the minimum amount needed to meet volume, 
octane, and/or total toxics performance requirements. Applying the max-
RFG and min-RFG criteria resulted in a total of four different 2012 
ethanol consumption control cases:

2.2-1.

    1. 7.2 billion gallons of ethanol, maximum amount used in RFG 
areas;

areas; and

areas.

    Once we determined how much ethanol was likely to be used in RFG 
areas (by PADD), we systematically allocated the remaining ethanol into 
conventional gasoline. First it was apportioned to winter oxy-fuel 
areas. In the 2004 base case, there were 14 state-implemented winter 
oxy-fuel programs in 11 states. Of these programs, 9 were required in 
response to non-attainment with the CO National Ambient Air Quality 
Standards (NAAQS) and 4 were implemented to maintain CO attainment 
status.\54\ By 2012, 4 areas are expected to be redesignated to CO 
attainment status and discontinue oxy-fuel use and 2 areas are 
predicted to discontinue using oxy-fuel as a maintenance strategy. 
Accordingly, a reduced amount of ethanol was allocated to oxy-fuel 
areas in 2012. The remaining ethanol was distributed to conventional 
gasoline (CG) in different states based on a computed ethanol margin 
(rack gasoline price minus ethanol delivered price adjusted by 
miscellaneous subsidies/penalties). The methodology is described in 
DRIA Section 2.1.4.3.
---------------------------------------------------------------------------

    \54\ Refer to DRIA Table 2.1-2.

    The main difference in the four resulting ethanol consumption 
scenarios was how far the ethanol penetrated the conventional gasoline 
pool. A summary of the forecasted 2012 ethanol consumption (by control 
case, fuel type and season) is found in Table VI.A.4-2.

    As expected, the least amount of ethanol was consumed in 
conventional gasoline in the 7.2 billion gallon control case when a 
maximum amount was allocated to RFG. Similarly, the most ethanol was 
consumed in CG in the 9.6 billion gallon control case when a minimum 
amount was allocated to RFG. For more information on the four resulting 
2012 control cases, refer to DRIA Section 2.1.4.6.

B. Overview of Biodiesel Industry and Future Production/Consumption

1. Characterization of U.S. Biodiesel Production/Consumption
    Historically, the cost to make biodiesel was an inhibiting factor 
to production in the U.S. The cost to produce biodiesel was high 
compared to the price of petroleum derived diesel fuel, even with 
consideration of the benefits of subsidies and credits provided by 
Federal and state programs. Much of the demand occurred as a result of 
mandates from states and local municipalities, which required the use

[[Page 55606]]

of biodiesel. However, over the past couple years biodiesel production 
has been increasing rapidly. The combination of higher crude oil prices 
and greater Federal tax subsidies has created a favorable economic 
situation. The Biodiesel Blenders Tax Credit programs and the Commodity 
Credit Commission Bio-energy Program, both subsidize producers and 
offset production costs. The Energy Policy Act extended the Biodiesel 
Blenders Tax Credit program to 2008. This credit provides about one 
dollar per gallon in the form of a Federal excise tax credit to 
biodiesel blenders from virgin vegetable oil feedstocks and 50 cents 
per gallon to biodiesel produced from recycled grease and animal fats. 
The program was started in 2004 under the American Jobs Act, spurring 
the expansion of biodiesel production and demand. Historical estimates 
and future forecasts of biodiesel production in the U.S. are presented 
in Table VI.B.1-1 below.

    With the increase in biodiesel production, there has also been a 
corresponding rapid expansion in biodiesel production capacity. 
Presently, there are 65 biodiesel plants in operation with an annual 
production capacity of 395 million gallons per year.\55\ The majority 
of the current production capacity was built in 2005, and was first 
available to produce fuel in the last quarter of 2005. Though capacity 
has grown, historically the biodiesel production capacity has far 
exceeded actual production with only 10-30 percent of this being 
utilized to make biodiesel, see Table VI.B.1-2.\56\

2. Expected Growth in U.S. Biodiesel Production/Consumption
    In addition to the 53 biodiesel plants already in production, as of 
early 2006, there were an additional 50 plants and 8 plant expansions 
in the construction phase, which when completed would increase total 
biodiesel production capacity to over one billion gallons per year. 
Most of these plants should be completed by early 2007. There were also 
36 more plants in various stages of the preconstruction phase (i.e. 
raising equity, permitting, conceptual design, buying equipment) with a 
capacity of 755 million gallons/year. As shown in Table VI.B.2-1, if 
all of this capacity came to fruition, U.S. biodiesel capacity would 
exceed 1.8 billion gallons.

    For cost and emission analysis purposes, three biodiesel usage 
cases were considered: A 2004 base case, a 2012 reference case, and a 
2012 control case. The 2004 base case was formed based on historical 
biodiesel usage (25 million gallons as summarized in Table VI.B.1.1). 
The reference case was computed by taking the 2004 base case and 
growing it out to 2012 in a manner consistent with the growth of 
gasoline.\57\ The resulting 2012 reference case consisted of 
approximately 28 million gallons of biodiesel. Finally, for the 2012 
control case, forecasted biodiesel use was assumed to be 300 million 
gallons based on EIA's AEO 2006 report (rounded value from Table 
VI.B.1.1). Unlike forecasted ethanol use, biodiesel use was assumed to 
be constant at 300 million gallons under both the statutory and higher 
projected renewable fuel consumption scenarios described in VI.A.4. 
EIA's projection is based on the assumption that the blender's tax 
credit is not renewed beyond 2008. If the tax credit is renewed, the 
projection for biodiesel demand would increase.

C. Feasibility of the RFS Program Volume Obligations

    This section examines whether there are any feasibility issues 
associated with the meeting the minimum renewable fuel requirements of 
the Energy Act. Issues are examined with respect to

[[Page 55607]]

renewable production capacity, cellulosic ethanol production capacity, 
and distribution system capability. Land resource requirements are 
discussed in Chapter 7 of the RIA.
1. Production Capacity of Ethanol and Biodiesel
    As shown in sections VI.A. and VI.B., increases in renewable fuel 
production capacity are already proceeding at a pace significantly 
faster than required to meet the 2012 mandate in the Act of 7.5 billion 
gallons. The combination of ethanol and biodiesel plants in existence 
and planned or under construction is expected to provide a total 
renewable fuel production capacity of over 9.6 billion gallons by the 
end of 2012. Production capacity is expected to continue to increase in 
response to strong demand. We estimate that this will require a maximum 
of 2,100 construction workers and 90 engineers on a monthly basis 
through 2012.
2. Production Capacity of Cellulosic Ethanol
    Beginning in 2013, a minimum of 250 million gallons per year of 
cellulosic ethanol must be used in gasoline. The Act's definition of 
cellulosic, however, includes corn based ethanol as long as greater 
than 90% of the process energy was derived from animal wastes or other 
waste materials. As discussed in section VI.A. above, we believe that 
of the ethanol plants currently in existence, under construction, or in 
the final stages of planning there is likely to be more than 250 
million gallons per year of ethanol produced from plants which meet 
these alternative definitions for cellulosic ethanol.
    However, this is not to say that ethanol produced from cellulose 
will not be part of the renewable supply by 2012. As far as we know 
there is currently only one demonstration-level cellulosic ethanol 
plant in operation in North America; it produces 1 million gallons of 
ethanol per year (Iogen a privately held company, based in Ottawa, 
Ontario, Canada). However, the technology used to produce ethanol from 
cellulosic feedstocks continues to improve. With the grants made 
available through the Energy Act, we expect several cellulosic process 
plants will be constructed and an ever increasing effort will naturally 
be made to find better, more efficient ways to produce cellulosic 
ethanol.
    To produce ethanol from cellulosic feedstocks, pretreatment is 
necessary to hydrolyze cellulosic and hemicellulosic polymers and break 
down the lignin sheath. In so doing, the structure of the cellulosic 
feedstock is opened to allow efficient and effective enzyme hydrolysis 
of the cellulose/hemicellulose to glucose and xylose. The central 
problem is that the [alpha]-linked saccharide polymers in the 
cellulose/hemicellulose structure prevent the microbial fermentation 
reaction. By comparison, when corn kernels are used as feedstock, 
fermentation of the starch produced from the corn kernels which have 
[alpha]-linked saccharide polymers takes place much more readily. An 
acid hydrolysis process was developed to pretreat cellulosic feedstocks 
(through hydrolysis which breaks up the [beta]-links), but it continues 
to be prohibitively expensive for producing ethanol.
    Some technologies that are being developed may solve some of the 
problems associated with production of ethanol from cellulosic sources. 
Specifically, one problem with cellulosic feedstocks is that the 
hydrolysis reactions produce both glucose, a six-carbon sugar, and 
xylose, a five-carbon sugar (pentose sugar, 
C<INF>5</INF>H<INF>10</INF>O<INF>5</INF>; sometimes called ``wood 
sugar''). Early conversion technology required different microbes to 
ferment each sugar. Recent research has developed better cellulose 
hydrolysis enzymes and ethanol-fermenting organisms. Now, glucose and 
xylose can be co-fermented--hence, the present-day terminology: Weak-
acid enzymatic hydrolysis and co-fermentation. In addition, several 
research groups, using recently developed genome modifying technology, 
have been able to produce a variety of new or modified enzymes and 
microbes that show promise for use in a process known as weak-acid, 
enzymatic-prehydrolysis.
    Cellulosic biomass can come from a variety of sources. Because the 
conversion of cellulosic biomass to ethanol has not yet been 
commercially demonstrated, we cannot say at this time which feedstocks 
are superior to others. In particular, there is only one cellulosic 
ethanol plant in North America (Iogen, Ottawa, Ontario, Canada). To the 
best of our knowledge, the technology that Iogen employs is not yet 
fully developed or optimized. Generally, the industry seems to be 
moving toward a process that uses dilute acid enzymatic prehydrolysis 
with simultaneous saccharification (enzymatic) and co-fermentation.
3. Renewable Fuel Distribution System Capability
    Ethanol and biodiesel blended fuels are not shipped by petroleum 
product pipeline due to operational issues and additional cost factors. 
Hence, a separate distribution system is needed for ethanol and 
biodiesel up to the point where they are blended into petroleum-based 
fuel as it is loaded into tank trucks for delivery to retail and fleet 
operators. In cases where ethanol and biodiesel are produced within 200 
miles of a terminal, trucking is often the preferred means of 
distribution. For longer shipping distances, the preferred method of 
bringing renewable fuels to terminals is by rail and barge.
    Modifications to the rail, barge, tank truck, and terminal 
distribution systems will be needed to support the transport of the 
anticipated increased volumes of renewable fuels. These modifications 
include the addition of terminal blending systems for ethanol and 
biodiesel, additional storage tanks at terminals, additional rail 
delivery systems at terminals for ethanol and biodiesel, and additional 
rail cars, barges, and tank trucks to distribute ethanol and biodiesel 
to terminals. Terminal storage tanks for 100 percent biodiesel will 
also need to be heated during cold months to prevent gelling. In the 
past the refining industry has raised concerns regarding whether the 
distribution infrastructure can expand rapidly enough to accommodate 
the increased demand for ethanol. The most comprehensive study of the 
infrastructure requirements for an expanded fuel ethanol industry was 
conducted for the Department of Energy (DOE) in 2002.\58\ The 
conclusions reached in that study indicate that the changes needed to 
handle the anticipated increased volume of ethanol by 2012 will not 
represent a major obstacle to industry. While some changes have taken 
place since this report was issued, including an increased reliance on 
rail over marine transport, we continue to believe that the rail and 
marine transportation industries can manage the increased growth in 
demand in an orderly fashion. This belief is supported by the 
demonstrated ability for the industry to handle the rapid increases and 
redistribution of ethanol use across the country over the last several 
years as MTBE was removed. The necessary facility changes at terminals 
and at retail stations to dispense ethanol containing fuels have been 
occurring at a record pace. Given that future growth is expected to 
progress at a steadier pace and with greater advance warning in 
response to economic drivers, we anticipate that the distribution 
system will be able to respond appropriately. A discussion of the costs 
associated making the changes discussed above is

VII. Impacts on Cost of Renewable Fuels and Gasoline

    This section examines the impact on fuel costs resulting from the 
growth in renewable fuel use between a base year of 2004 and 2012. We 
note that based on analyses conducted by the Energy Information 
Administration (EIA), renewable fuels will be used in gasoline and 
diesel fuel in excess and independent of the RFS requirements. As such, 
the changes in the use of renewable fuels and their related cost 
impacts are not directly attributable to the RFS rule. Rather, our 
analysis assesses the broader fuels impacts of the growth in renewable 
fuel use in the context of corresponding changes to the makeup of 
gasoline. These fuel impacts include the elimination of the 
reformulated gasoline (RFG) oxygen standard which has resulted in the 
refiners ceasing to use the gasoline blendstock methyl tertiary butyl 
ether (MTBE) and replacing it with ethanol. We also expect that by 
ending the use of MTBE that the former MTBE feedstock, isobutylene, 
will be reused to produce increased volumes of alkylate, a moderate to 
high octane gasoline blendstock. Thus, in this analysis, we are 
assessing the impact on the cost of gasoline and diesel fuel of 
increased use of renewable fuels, the cost savings resulting from the 
phase out of MTBE and the increased cost due to the production of 
alkylate.
    As discussed in section II., we chose to analyze a range of 
renewable fuels use. In the case of ethanol's use in gasoline, the 
lower end of this range is based on the minimum renewable fuel volume 
requirements in the Act, and the higher end is based on AEO 2006. At 
both ends of this range, we assume that biodiesel consumption will be 
the level estimated in AEO 2006. We analyzed the projected fuel 
consumption scenario and associated program costs in 2012, the year 
that the RFS is fully phased-in. The volumes of renewable fuels 
consumed in 2012 at the two ends of the range are summarized in Table 
VII-1.

    Total Biofuel Consumption...........            7.5             9.90
------------------------------------------------------------------------

    We have estimated an average corn ethanol production cost of $1.20 
per gallon in 2012 (2004 dollars) in the case of 7.5 billion gallons 
per year (bill gal/yr) and $1.26 per gallon in the case of 9.9 bill 
gal/yr. For cellulosic ethanol, we estimate it will cost approximately 
$1.65 in 2012 (2004 dollars) to produce a gallon of ethanol using corn 
stover as a cellulosic feedstock. In this analysis, however, we assume 
that the cellulosic requirement will be met by corn-based ethanol 
produced by energy sourced from biomass (animal and other waste 
materials as discussed in Section III.B of this preamble) and costing 
the same as corn based ethanol produced by conventional means.
    We estimated production costs for soy-derived biodiesel of $2.06 
per gallon in 2004 and $1.89 per gal in 2012. For yellow grease derived 
biodiesel, we estimate an average production cost of $1.19 per gallon 
in 2004 and $1.10 in 2012.
    The impacts on overall gasoline costs with and without fuel 
consumption subsidies resulting from the increased use of ethanol and 
the corresponding changes to the other aspects of gasoline were 
estimated for both of these cases. The 7.5 bill gal/yr case would 
result in increased total costs which range from 0.33 cents to 0.41 
cents per gallon depending on assumptions with respect to ethanol use 
in RFG and butane control constraints. The 9.9 bill gal/yr case would 
result in increased total costs which range from 0.93 to 1.05 cents per 
gallon. The actual cost at the fuel pump, however, will be decreased 
due the effect of State and Federal tax subsidies for ethanol. Taking 
this into consideration results in ``at the pump'' decreased costs 
(cost savings) ranging from 0.82 to 0.89 cents per gallon for the 7.5 
bill gal/yr case and ``at the pump'' decreased costs ranging from 0.98 
to 1.08 cents per gallon for the 9.9 bill gal/yr case. We ask for 
comment on these derived costs as well as on the analysis methodology 
used to derive these costs, and refer the reader to Section 7 of the 
DRIA which contains much more detail on the cost analysis used to 
develop these costs.

A. Renewable Fuel Production and Blending Costs

1. Ethanol Production Costs
    a. Corn Ethanol. A significant amount of work has been done in the 
last decade on surveying and modeling the costs involved in producing 
ethanol from corn, to serve business and investment purposes as well as 
to try to educate energy policy decisions. Corn ethanol costs for our 
work were estimated using a model developed by USDA in the 1990s that 
has been continuously updated by USDA. The most current version was 
documented in a peer-reviewed journal paper on cost modeling of the 
dry-grind corn ethanol process,\59\ and it produces results that 
compare well with cost information found in surveys of existing 
plants.\60\ We made some minor modifications to the USDA model to allow 
scaling of the plant size, to allow consideration of plant energy 
sources other than natural gas, and to adjust for energy prices in 
2012, the year of our analysis.

Production Survey (published July 2005).
---------------------------------------------------------------------------

    The cost of ethanol production is most sensitive to the prices of 
corn and the primary co-product, DDGS. Utilities, capital, and labor 
expenses also have an impact, although to a lesser extent. Corn 
feedstock minus DDGS sale credits represents about 50% of the final 
per-gallon cost, while utilities, capital and labor comprise about 20%, 
10%, and 5%, respectively. For this work, we used corn price 
projections from USDA of $2.23 per bushel in 2012 for the 7.2 bill gal/
yr case, and an adjusted value of $2.31 per bushel for the 9.6 bill 
gal/yr

[[Page 55609]]

case.\61\ The adjustment at the higher volume case was taken from work 
done by FAPRI and EIA.<SUP>62 63</SUP> Prices used for DDGS were $65 
per ton in the 7.2 bill gal/yr case and $55 per ton in the 9.6 case, 
based on work by FAPRI and EIA.\64\ Energy prices were derived from 
historical data and projected to 2012 using EIA's AEO 2006.\65\ While 
we believe the use of USDA and FAPRI estimates for corn and DDGS prices 
is reasonable, additional modeling work is being done for the final 
rulemaking using the Forestry and Agricultural Sector Optimization 
Model described further in Chapter 8 of the RIA.

for operations, capital depreciation, labor, overhead, and denaturant, 
minus revenue from sale of co-products. It does not account for any 
subsidies on production or sale of ethanol. This cost is independent of 
the market price of ethanol, which has been related closely to the 
wholesale price of gasoline for the past decade.<SUP>66 67</SUP>

---------------------------------------------------------------------------

    Under the Energy Act, starch-based ethanol can be counted as 
cellulosic if at least 90% of the process energy is derived from 
renewable feedstocks, which include plant cellulose, municipal solid 
waste, and manure biogas.\68\ It is expected that the 250 million 
gallons per year of cellulosic ethanol production required by 2013 will 
be made using this provision. While we have been unable to develop a 
detailed production cost estimate for corn ethanol meeting cellulosic 
criteria, we assume that the costs will not be significantly different 
from conventionally produced corn ethanol. We believe this is 
reasonable because these processes will simply be corn ethanol plants 
with additional fuel handling mechanisms that allow them to combust 
waste materials for process energy instead of natural gas. We expect 
them to be in locations where the very low or zero cost of the waste 
material or biogas itself will likely offset the costs of hauling it 
and/or the additional capital for processing and firing it, making them 
cost-competitive with conventional corn ethanol plants. Furthermore, 
because the quantity of ethanol produced using these processes is still 
expected to be a relatively small fraction of the total ethanol demand, 
the sensitivity of the overall analysis to this assumption is also very 
small. Based on these factors, we have assigned starch ethanol made 
using this cellulosic criteria the same cost as ethanol produced from 
corn using conventional means.

    b. Cellulosic Ethanol. In 1999, the National Renewable Energy 
Laboratory (NREL) published a report outlining its work with the USDA 
to design a computer model of a plant to produce ethanol from hardwood 
chips.\69\ Although the model was originally prepared for hardwood 
chips, it was meant to serve as a modifiable-platform for ongoing 
research using cellulosic biomass as feedstock to produce ethanol. 
Their long-term plan was that various indices, costs, technologies, and 
other factors would be regularly updated.

---------------------------------------------------------------------------

    NREL and USDA used a modified version of the model to compare the 
cost of using corn-grain with the cost of using corn stover to produce 
ethanol. We used the corn stover model from the second NREL/USDA study 
for the analysis for this proposed rule. Because there were no 
operating plants that could potentially provide real world process 
design, construction, and operating data for processing cellulosic 
ethanol, NREL had considered modeling the plant based on assumptions 
associated with a first-of-a-kind or pioneer plant. The literature 
indicates that such models often underestimate actual costs since the 
high performance assumed for pioneer process plants is generally 
unrealistic.
    Instead, the NREL researchers assumed that the corn stover plant 
was an N<INF>th</INF> generation plant, e.g., not a pioneer plant or 
first-or-its kind, built after the industry had been sufficiently 
established to provide verified costs. The corn stover plant was 
normalized to the corn kernel plant, e.g., placed on a similar 
basis.\70\ It is also reasonable to expect that the cost of cellulosic 
ethanol would be higher than corn ethanol because of the complexity of 
the cellulose conversion process. Recently, process improvements and 
advancements in corn production have considerably reduced the cost of 
producing corn ethanol. We also believe it is realistic to assume that 
cellulose-derived ethanol process improvements will be made and that 
one can likewise reasonably expect that as the industry matures, the 
cost of producing ethanol from cellulose will also decrease.

---------------------------------------------------------------------------

    We calculated fixed and variable operating costs using percentages 
of direct labor and total installed capital costs. Following this 
methodology, we estimate that producing a gallon of ethanol using corn 
stover as a cellulosic feedstock would cost $1.65 in 2012 (2004 
dollars).
    c. Ethanol's Blending Cost. Ethanol has a high octane value of 115 
(R+M)/2 which contributes to its value as a gasoline blendstock. As the 
volume of ethanol blended into gasoline increases from 2004 to 2012, 
refiners will account for the octane provided by ethanol when they plan 
their gasoline production. This additional octane would allow them to 
back off of their octane production from their other gasoline producing 
units resulting in a cost savings to the refinery. For this cost 
analysis, the cost savings is expressed as a cost credit to ethanol 
added to the production cost for producing ethanol.
    We obtained gasoline blending costs on a PADD basis for octane from 
a consultant who conducted a cost analysis for a renewable fuels 
program using an LP refinery cost model. LP refinery models value the 
cost of octane based on the octane producing capacity for the 
refinery's existing units, by

[[Page 55610]]

added capital and operating costs for new octane producing capacity, 
and based on purchased gasoline blendstocks. The value of octane is 
expressed as a per-gallon cost per octane value, and ranges from 0.38 
cents per octane-gallon in PADD 2 where lots of ethanol is expected to 
be used, to 1.43 cents per octane-gallon in California. Octane is more 
costly in California because the Phase 3 RFG standards restriction 
aromatics content which also reduces the use of a gasoline blendstock 
named reformate--a relatively cheap source of octane. Also, 
California's Phase 3 RFG distillation restrictions tend to limit the 
volume of eight carbon alkylate, another lower cost and moderately high 
octane blendstock.
    Another blending factor for ethanol is its energy content. Ethanol 
contains a lower heat content per gallon than gasoline. Since refiners 
blend up their gasoline based on volume, they do not consider the 
energy content of its gasoline, only its price. Instead, the consumer 
pays for a gasoline's energy density based on the distance that the 
consumer can achieve on a gallon of gasoline. Since we try to capture 
all the costs of using ethanol, we consider this effect. Ethanol 
contains 76,000 British Thermal Units (BTU) per gallon which is 
significantly lower than gasoline, which contains an average of 115,000 
BTUs per gallon. This lower energy density is accounted for below in 
the discussion of the gasoline costs.
2. Biodiesel Production Costs
    We based our cost to produce biodiesel fuel on a range estimated 
from the use of USDA's and NREL's biodiesel computer models. Both of 
these models represent the continuous transesterification process for 
converting vegetable soy oil to esters, along with the ester finishing 
processes and glycerol recovery. The models estimate biodiesel 
production costs using prices for soy oil, methanol, chemicals and the 
byproduct glycerol. The models estimate the capital, fixed and 
operating costs associated with the production of soy based biodiesel 
fuel, considering utility, labor, land and any other process and 
operating requirements.
    Each model is based on a medium sized biodiesel plant that was 
designed to process raw degummed virgin soy oil as the feedstock, 
yielding 10 million gallons per year of biodiesel fuel. USDA estimated 
the equipment needs and operating requirements for their biodiesel 
plant through the use of process simulation software. This software 
determines the biodiesel process requirements based on the use of 
established engineering relationships, process operating conditions and 
reagent needs. To substantiate the validity and accuracy of their 
model, USDA solicited feedback from major biodiesel producers. Based on 
responses, they then made adjustments to their model. The NREL model is 
also based on process simulation software, though the results are 
adjusted to reflect NREL's modeling methods.
    The production costs are based on an average biodiesel plant 
located in the Midwest using soy oil and methanol, which are catalyzed 
into esters and glycerol by use of sodium hydroxide. Because local 
feedstock costs, distribution costs, and biodiesel plant type introduce 
some variability into cost estimates, we believe that using an average 
plant to estimate production costs provides a reasonable approach. 
Therefore, we simplified our analysis and used costs based on an 
average plant and average feedstock prices since the total biodiesel 
volumes forecasted are not large and represent a small fraction of the 
total projected renewable volumes. The production costs are based on a 
plant that makes 10 million gallons per year of biodiesel fuel.
    The model is further modified to use input prices for the 
feedstocks, byproducts and energy prices to reflect the effects of the 
fuels provisions in the Energy Act. Based on the USDA model, for soy 
oil-derived biodiesel we estimate a production cost of $2.06 per gallon 
in 2004 and $1.89 per gal in 2012 (in 2004 dollars) For yellow grease 
derived biodiesel, USDA's model estimates an average production cost of 
$1.19 per gallon in 2004 and $1.10 in 2012 (in 2004 dollars). In order 
to capture a range of production costs, we compared these cost 
projections to those derived from the NREL biodiesel model. With the 
NREL model, we estimate biodiesel production cost of $2.11 per gallon 
for soy oil feedstocks and $1.28 per gallon for yellow grease in 2012, 
which are slightly higher than the USDA results.
    With the current Biodiesel Blender Tax Credit Program, producers 
using virgin vegetable oil stocks receive a one dollar per gallon tax 
subsidy while yellow grease producers receive 50 cents per gallon, 
reducing the net production cost to a range of 89 to 111 cents per 
gallon for soy derived biodiesel and 60 to 78 cents per gallon for 
yellow grease biodiesel in 2012. This compares favorably to the 
projected wholesale diesel fuel prices of 138 cents per gallon in 2012, 
signifying that the economics for biodiesel are positive under the 
effects of the blender credit program, though, the tax credit program 
expires in 2008 if not extended. Congress may later elect to extend the 
blender credit program, though, following the precedence used for 
extending the ethanol blending subsidies. Additionally, the Small 
Biodiesel Blenders Tax credit program and state tax and credit programs 
offer some additional subsidies and credits, though the benefits are 
modest in comparison to the Blender's Tax credit.
3. Diesel Fuel Costs
    Biodiesel fuel is blended into highway and nonroad diesel fuel, 
which increases the volume and therefore the supply of diesel fuel and 
thereby reduces the demand for refinery-produced diesel fuel. In this 
section, we estimate the overall cost impact, considering how much 
refinery-based diesel fuel is displaced by the forecasted production 
volume of biodiesel fuel. The cost impacts are evaluated considering 
the production cost of biodiesel with and without the subsidy from the 
Biodiesel Blenders Tax credit program. Additionally, the diesel cost 
impacts are quantified under two scenarios, with refinery diesel prices 
as forecasted by EIA's AEO 2006 with crude at $47 a barrel and with 
refinery diesel prices based on $70 per barrel crude oil.
    We estimate the net effect that biodiesel production has on overall 
cost for diesel fuel in year 2012 using total production costs for 
biodiesel and diesel fuel. The costs are evaluated based on how much 
refinery-based diesel fuel is displaced by the biodiesel volumes as 
forecasted by EIA, accounting for energy density differences between 
the fuels. The cost impact is estimated from a 2004 year basis, by 
multiplying the production costs of each fuel by the respective changes 
in volumes for biodiesel and estimated displaced diesel fuel. We 
further assume that all of the forecasted biodiesel volume is used as 
transport fuel, neglecting minor uses in the heating oil market.
    For the AEO scenario, the net effect of biodiesel production on 
diesel fuel costs, including the biodiesel blenders' subsidy, is a 
reduction in the cost of transport diesel fuel costs by $90 million per 
year, which equates to a reduction in fuel cost of about 0.15 c/
gal.\71\ Without the subsidy, the transport diesel fuel costs are 
increased by $118 million per year, or an increase of 0.20 c/gal for 
transport diesel fuel. With crude at $70 per barrel, including the 
biodiesel blenders subsidy, results in a cost reduction of $184 million 
per

[[Page 55611]]

year, or a reduction of 0.31 c/gal for the total transport diesel pool. 
Without the subsidy, transport diesel costs are increased by $25 
million per year, or 0.04 c/gal.
---------------------------------------------------------------------------

    \71\ Based on EIA's AEO 2006, the total volume of highway and 
off-road diesel fuel consumed in 2012 was estimated at 58.9 billion 
gallons.
---------------------------------------------------------------------------

B. Distribution Costs

1. Ethanol Distribution Costs
    There are two components to the costs associated with distributing 
the volumes of ethanol necessary to meet the requirements of the 
Renewable Fuels Standard (RFS): (1) the capital cost of making the 
necessary upgrades to the fuel distribution infrastructure system, and 
(2) the ongoing additional freight costs associated with shipping 
ethanol to terminals. The most comprehensive study of the 
infrastructure requirements for an expanded fuel ethanol industry was 
conducted for the Department of Energy (DOE) in 2002.\72\ That study 
provided the foundation our estimates of the capital costs associated 
with upgrading the distribution infrastructure system as well as the 
freight costs to handle the increased volume of ethanol needed to meet 
the requirements of the RFS in 2012. Distribution costs are evaluated 
here for the case where the minimum volume of ethanol is used to meet 
the requirements of the RFS (7.2 bill gal/yr) and for the projected 
case where the volume of ethanol used is 9.6 bill gal/yr. The 2012 
reference case against which we are estimating the cost of distributing 
the additional volume of ethanol needed to meet the requirements of the 
RFS is 3.9 billion gallons.

Industry, Downstream Alternatives Inc., January 15, 2002.
---------------------------------------------------------------------------

    a. Capital Costs To Upgrade Distribution System For Increased 
Ethanol Volume. The 2002 DOE study examined two cases regarding the use 
of renewable fuels for estimating the capital costs for distributing 
additional ethanol. The first assumed that 5.1 bill gal/yr of ethanol 
would be used in 2010, and the second assumed that 10 bill gal/yr of 
ethanol would be used in the 2015 timetable. We interpolated between 
these two cases to provide an estimate of the capital costs to support 
the use of 7.2 bill gal/yr of ethanol in 2012.\73\ The 10 bill gal/yr 
case examined in the DOE study was used to represent the projected case 
examined in today's rule of 9.6 bill gal/yr of ethanol.\74\ Table 
VII.B.1.a-1 contains our estimates of the infrastructure changes and 
associated capital costs for the two ethanol use scenarios examined in 
today's rule. Amortized over 15 years, the total capital costs equate 
to approximately one cent per gallon. We performed a sensitivity 
analysis where we increased reliance on rail use at the expense of 
barge use in transporting ethanol. The costs were relatively 
insensitive, increasing to just 1.1 cents per gallon.
---------------------------------------------------------------------------

    \73\ See Chapter 7.3 of the Draft Regulatory Impact Analysis 
associated with today's rule for additional discussion of how the 
results of the DAI study were adjusted to reflect current conditions 
in estimating the ethanol distribution infrastructure capital costs 
under today's rule.
    \74\ For both the 7.2 bill gal/yr and 9.6 bill gal/yr cases, the 
baseline from which the DOE study cases were projected was adjusted 
to reflect a 3.9 bill gal/yr 2012 baseline.

    b. Ethanol Freight Costs. The DOE study contains ethanol freight 
costs for each of the 5 PADDs. The Energy Information Administration 
translated these cost estimates to a census division basis.\75\ We took 
the EIA projections and translated them into State-by-State ethanol 
freight costs. In conducting this translation, we accounted for 
increases in the cost in transportation fuels used to ship ethanol by 
truck, rail, and barge. We estimate that the freight cost to transport 
ethanol to terminals would range from 5 cents per gallon in the 
Midwest, to 18 cents per gallon to the West Coast, which averages 9.2 
cents per gallon of ethanol on a national basis.
---------------------------------------------------------------------------

System, Part 2, March 2006, DOE/EIA-059 (2006), http://tonto.eia.doe.gov/FTPROOT/modeldoc/m059(2006)-2.pdf.
---------------------------------------------------------------------------

    We estimate the total cost for producing and distributing ethanol 
to be between $1.30 and $1.36 per gallon of ethanol, on a nationwide 
average basis. This estimate includes both the capital costs to upgrade 
the distribution system and freight costs.
2. Biodiesel Distribution Costs
    The volume of biodiesel used by 2012 under the RFS is estimated at 
300 million gallons per year. The 2012 baseline case against which we 
are estimating the cost of distributing the additional volume of 
biodiesel is 28 million gallons.\76\
---------------------------------------------------------------------------

    \76\ 2004 baseline of 25 million gallons grown with diesel 
demand to 2012.
---------------------------------------------------------------------------

    For the purposes of this analysis, we are assuming that to ensure 
consistent operations under cold conditions all terminals will install 
heated biodiesel storage tanks and biodiesel will be transported to 
terminals in insulated tank trucks and rail cars in the cold 
seasons.\77\ Due to the developing nature of the biodiesel industry, 
specific information on biodiesel freight costs is lacking. The need to 
protect biodiesel from gelling during the winter may marginally 
increase freight costs over those for ethanol. Counterbalancing this is 
the likelihood that biodiesel shipping distances may be somewhat 
shorter due to the more geographically dispersed nature of biodiesel 
production facilities. In any event, the potential difference between 
biodiesel and ethanol freight costs is likely to be small and the cost 
of distributing biodiesel does not appreciably affect the results of 
our analysis. Therefore, we believe that

[[Page 55612]]

estimated freight costs for ethanol of 9.2 cents per gallon adequately 
reflects the freight costs for biodiesel for this analysis.
---------------------------------------------------------------------------

    \77\ See section VI.C. in today's preamble regarding the special 
handling requirements for biodiesel under cold conditions.
---------------------------------------------------------------------------

    The capital costs associated with distribution of biodiesel will be 
somewhat higher per gallon than those associated with the distribution 
of ethanol due to the need for storage tanks, barges, tanker trucks and 
rail cars to be insulated and in many cases heated. We estimate that to 
handle the increased biodiesel volume will require a total capital cost 
investment of $49,813,000, which equates to about 2 cents per gallon of 
new biodiesel volume.
    We estimate the total cost for producing and distributing biodiesel 
to be between $2.00 and $2.22 per gallon of biodiesel, on a nationwide 
average basis. This estimate includes both the capital costs to upgrade 
the distribution system and freight costs.

C. Estimated Costs to Gasoline

    To estimate the cost of increased use of renewable fuels, the cost 
savings from the phase out of MTBE and the production cost of alkylate, 
we developed our own spreadsheet cost model. As described above in 
Section VI.A, the cost analysis is conducted by comparing a base year 
before the Energy Act's fuel changes to a modeled year with the fuel 
changes. We used 2004 as the base year. We grew the 2004 gasoline 
demand to 2012 to create a reference case assuming that the 2004 fuel 
demand scenario remained the same (fuel quality remained constant). The 
sum of fuel changes, including the increased use of ethanol, the phase-
out of MTBE and the conversion of a part of the MTBE feedstocks to 
alkylate, is all assumed to occur by 2012 and is compared to the 2012 
reference case. This analysis considers the production cost, 
distribution cost as well as the cost for balancing the octane and RVP 
caused by these fuel changes.
    In addition to assessing the cost at 7.2 and 9.6 billion gallons of 
total ethanol use in gasoline, we considered that ethanol could be used 
at different levels in RFG. Instead of picking a single point for 
ethanol use in RFG, we assessed a range (see Section VI.A above). At 
the high end of the range, ethanol is used in RFG in both summer and 
winter. At the low end of the range, ethanol is still used in 
wintertime RFG, but to only a very limited extent in summertime RFG. 
The lower rate of ethanol use in summertime RFG may occur because the 
RVP increase associated with ethanol will cause refiners to incur a 
cost to further control the volatility of their summertime RFG.
1. RVP Cost for Blending Ethanol Into Summertime RFG
    Blending ethanol into summertime RFG causes about a 1 PSI (pounds 
per square inch) increase in RVP. To enable this gasoline to continue 
to be sold into the summertime RFG market, this vapor pressure increase 
must be accounted for by adjusting the RVP of the base gasoline. The 
vapor pressure adjustment is made by reducing of volume of pentanes in 
the gasoline boiling that comes from the fluid catalytic cracking unit 
(FCCU). To reduce the pentane content FCC naphtha, refiners would 
likely have to add a distillation column called a depentanizer, where 
pentanes and lighter hydrocarbons are removed from the hydrocarbon feed 
and drawn off the top of the column while the heavier C6+ hydrocarbons 
are removed from the bottom. While the pentanes would be removed from 
the summertime RFG pool, they are expected to be reblended into either 
summertime CG or wintertime CG and RFG. To rebalance the RVP of the 
nonsummertime RFG pool or wintertime RFG or CG pool caused by relocated 
pentanes, butanes are estimated to be removed from the gasoline pool. 
When ethanol is blended into summertime RFG, about 10 percent of the 
base gasoline is lost due to the removed pentanes. We believe that 
refiners would reblend these removed pentanes into summertime CG or 
wintertime CG and RFG and rebalance the RVP of the gasoline pool into 
which the pentanes are being reblended by removing butanes, thus 
reducing the volume loss to one fifth of that if the pentanes were 
permanently removed. There is an opportunity cost to removing butanes 
from gasoline. In 2004 butanes sold into the butane market were valued 
36 cents per gallon less than gasoline, however, this opportunity cost 
would be much greater if pentanes were permanently removed from 
gasoline.
    We developed cost estimates for adding and operating a new 
depentanizer distillation column for the removal of pentanes from FCC 
naphtha in each refinery. The feed rate for an average FCC unit was 
estimated by PADD and ranged from 7 to 35 thousand barrels per day. 
Once the capital and operating costs were estimated, the total costs 
were averaged over the entire gasoline pool, which ranged from about 
two to three times the volume of FCC naphtha. When ethanol is being 
blended newly into summertime RFG, the capital and operating costs will 
both apply. However, when we model ethanol coming out of a summertime 
RFG market, we only reduce the depentanizer operating costs since the 
capital costs are sunk.
    Our analysis showed that the RVP blending costs for blending 
ethanol into summertime RFG ranges from 1 to 1.4 cents per gallon of 
RFG. If the ethanol is coming out of summertime RFG, which occurs in 
some of the scenarios that we modeled, there would be a cost savings of 
0.8 to 1.2 cents per gallon of RFG.
    In the cost of refinery gasoline section below, we took into 
account that butanes have a lower energy density compared to the 
gasoline pool from which the butanes were removed. This energy content 
adjustment will offset some of the cost for removing the butanes. 
Butane's energy density is 94,000 BTUs per gallon compared to 115,000 
BTU per gallon for gasoline.
    For further details on RVP reduction costs, see Section 7.4.2 of 
the RIA.
2. Cost Savings for Phasing Out Methyl Tertiary Butyl Ether (MTBE)
    The Energy Act rescinded the oxygen standard for RFG and when the 
provision took effect, U.S. refiners stopped blending MTBE into 
gasoline. When MTBE use ended, the operating costs for operating those 
plants also ceased. The total costs saved for not operating the MTBE 
plants is calculated by multiplying the volume of MTBE no longer 
blended into gasoline with the operating costs for the plants producing 
that MTBE.
    We determined the operating costs saved by shutting down these 
plants. The volumetric feedstock demands and the operating costs 
factors for each of these MTBE plants are taken from literature. We 
estimated the MTBE operating costs to be $1.40 per gallon for captive 
and ethylene cracker plants, $1.48 per gallon for propylene oxide 
plants and $1.55 per gallon for merchant operating costs. Weighted by 
the percentages for domestic MTBE production, the average cost savings 
for no longer producing MTBE is estimated to be $1.46 per gallon.
    We also credited MTBE for its octane blending value. MTBE has a 
high octane value of 110 (R+M)/2 which increases its value compared to 
gasoline. This high octane value partially offsets its production cost. 
The cost of octane is presented above in subsection VII.(A)(1)(c) and 
is applied to the difference in octane value between MTBE and the 
average of the various gasoline grades (88 (R+M)/2). Accounting for 
MTBE's octane value reduces its cost down to $1.27 to $1.38 per gallon 
depending on the PADD. When accounting for the volume of

[[Page 55613]]

MTBE removed, we also adjust for its energy content, which is 93,500 
BTU per gallon.
    For further information on costs savings due to MTBE phaseout, see 
Section 7.4.3 of the RIA.
3. Production of Alkylate From MTBE Feedstocks
    Discontinuing the blending of MTBE into U.S. gasoline is expected 
to result in the reuse of most of the primary MTBE feedstocks, 
isobutylene, to be used to produce alkylate. Alkylate is formed by 
reacting isobutylene together with isobutane. Prior to the 
establishment of the oxygen requirement for RFG, this isobutylene was, 
in most cases, used to make alkylate. Another option would be for 
reacting isobutylene with itself to form isooctene which would likely 
be hydrogenated to then form isooctane. However, our cost analysis 
found that alkylate is a more cost-effective way to reuse the 
isobutylene, even after considering isooctane's higher octane content. 
The cost for converting to alkylate is estimated to be $1.42 per gallon 
for captive (in-refinery) plants and ethylene cracker plants, $1.46 per 
gallon for propylene oxide plants and $1.52 per gallon for merchant 
MTBE plants. We believe that the cost for converting merchant MTBE 
plants to alkylate is too high to support its conversion, thus the 
conversion cost is estimated to be $1.43 per gallon, the average of the 
conversion costs for captive, ethylene cracker and propylene oxide MTBE 
plants. This projected percent of MTBE plant conversion results in 0.84 
gallons of alkylate produced for each gallon of MTBE no longer 
produced.
    The alkylate production cost is adjusted by PADD to account for the 
blending octane of alkylate, which varies by 1 to 2 cents per gallon 
depending on the value of octane in each PADD. Including its octane 
value, the cost of producing alkylate varies from $1.38 to $ 1.41 per 
gallon.
    For further information on production of alkylate from MTBE 
feedstocks, see section 7.4.4 of the RIA.
4. Changes in Refinery Produced Gasoline Volume and Its Costs
    In the sections above, we estimated changes in gasoline volume and 
the cost associated with those volume changes for ethanol, MTBE, 
alkylate and butane. As these various gasoline blendstocks are added to 
or removed from the gasoline pool, they affect the refinery production 
of gasoline (or oxygenate blendstock).
    To estimate the changes in refinery gasoline production volumes, it 
was necessary to balance the total energy production of each control 
case to the reference case. The energy content of the reference case 
was estimated by multiplying the volumetric energy content of each 
gasoline pool blendstock, including MTBE, ethanol and refinery produced 
gasoline, by the associated gallons.
    The increase or decrease in ethanol content in summertime RFG 
assumed under the different scenarios resulted in the change in the 
volumes of butane in RFG as described above. We identified that the 
increase or decrease in ethanol in wintertime RFG and CG could cause 
reductions or increases in the amount of butanes blended into 
wintertime gasoline. Wintertime gasoline is limited in vapor pressure 
by the American Standard for Testing Materials (ASTM) RVP and V/L 
(vapor-liquid) standards. According to a refiner with extensive 
refining capacity, and also Jacobs Engineering, a refining industry 
consulting firm, refineries are blending their wintertime gasoline up 
to those standards today and are limited from blending more butane 
available to them. If this is the case, for each gallon of summertime 
RFG and wintertime RFG and CG blended with ethanol 2 percent of the 
base gasoline volume would be lost in terms of butane removed. However, 
some refineries may have room to blend more butane. Also, we are aware 
that some states offer 1 PSI waivers for blending of ethanol into 
wintertime gasoline, presumably to accommodate splash blending of 
ethanol.\78\ Consequently, it may be possible to accommodate the 1 PSI 
vapor pressure increase without forcing the removal of some or all of 
this butane. For this reason we assessed the costs as a range, on the 
upper end assuming that butane content would have to be removed to 
account for new ethanol blended into summertime RFG and wintertime RFG 
and CG , and on the low end assuming only that blending of ethanol into 
summertime RFG cause butanes to be removed.
---------------------------------------------------------------------------

    \78\ Most people are aware of the 1 PSI RVP waiver that ethanol 
is provided for the summertime, but some states offer a similar 
waiver to ethanol for wintertime blending as well.
---------------------------------------------------------------------------

    For estimating the volume of butane which must be removed from the 
gasoline because of the addition of ethanol, we assumed that ethanol 
will be used at 10 volume percent except for California where it would 
continue to be used at 5.7 volume percent. Development of the estimates 
for winter vs. summer ethanol consumption for the control cases is 
discussed in Chapter 2.1 of the RIA. For the reference case, we 
estimated that 55 percent of the ethanol would be used in the winter 
and 45 percent in the summer. Table VII.C.4-1 summarizes the summertime 
RFG and wintertime RFG and CG volumes of ethanol and estimated change 
in butane content.

    The change in volume of ethanol, MTBE, alkylate, and butane for 
each control case is adjusted for energy content. The volume of 
refinery gasoline is then adjusted to maintain the same energy content 
as that of the reference gasoline pool. The refinery gasoline 
production is estimated by dividing the BTU content of gasoline, 
estimated to be 115,000 BTU per gallon, into the total amount of BTUs 
for the entire gasoline pool after accounting for the BTUs of the other 
blendstocks. The BTU-balanced gasoline pool volumes for each control 
case are shown in Table

VII.C.4-2. The changes are shown for both assumptions with respect to 
the need to remove butane from winter gasoline to accommodate more 
ethanol blending.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    Based on our estimated impacts on volumes shown in table VII.C.4-2, 
refinery produced gasoline demand will be reduced by a range of 1.3 
percent to 2.7 percent compared to the reference case, which would 
result in less imported finished petroleum products and/or less crude 
oil use. The projected impacts on refinery-produced gasoline demand 
depend on the volume of new ethanol blended into gasoline, on the 
volume of ethanol blended into summertime RFG and on whether butane 
blending into wintertime gasoline will be affected or not. To put this 
reduction in refinery-produced gasoline volume in perspective, the 
yearly annual growth in gasoline demand in this country is about 1.7 
percent.
    The cost for changes to refinery produced gasoline volume is 
assumed to be represented by the bulk price of gasoline in each PADD 
from EIA's 2004 Petroleum Marketing Annual. The 2004 gasoline cost is 
adjusted to 2012 using the ratio of the projected crude oil price in 
2012 of $47 per barrel to that in the 2004 base case of $41 per barrel. 
The cost for distributing the gasoline to terminals is added on, which 
is estimated to be 4 cents per gallon. The estimated cost for producing 
and distributing gasoline to terminals (wholesale price at the terminal 
rack) ranges from $1.30 per gallon in the Gulf Coast, to $1.53 per 
gallon in California.
    Crude oil prices are much higher today which decreases the relative 
cost of producing and blending in more ethanol into gasoline. For this 
reason, we conducted a sensitivity analysis assuming that crude oil is 
priced at around $70 per barrel. Since this is only a sensitivity 
analysis, we simply ratioed the gasoline production costs, MTBE and 
alkylate feedstock costs and butane value upwards by the same ratio. 
The ratio is determined by the projected increase in the wholesale 
gasoline price relative to the increase in crude oil price. We 
extrapolated this relationship to crude oil priced at $70 per barrel 
compared to the price in 2004 which was $41 per barrel, which results 
in about a 1.4 ratio factor. We did not adjust other costs and 
assumptions which are much less sensitive to the price of crude oil and 
therefore not likely to change much (e.g., distribution costs, refinery 
utility costs, incremental octane costs, and ethanol production costs). 
At a $70 per barrel crude oil price, the cost for production and 
distribution of gasoline to the terminal ranges from $2.05 in the Gulf 
Coast to $2.43 per gallon in California.
    For further information on gasoline cost see section 7.4.5 in the 
RIA.
5. Overall Impact on Fuel Cost
    We combined the costs and volume impacts described in the previous 
sections to estimate an overall fuel cost impact due to the changes in 
gasoline occurring with the projected fuel changes. This aggregated 
cost estimate includes the costs for producing and distributing 
ethanol, the blending costs of ethanol in summertime RFG, ending the 
production and distribution of MTBE, and reusing the MTBE feedstock 
isobutylene for producing alkylate, reducing the content of butane in 
summertime RFG and wintertime gasoline and for reducing the volume of 
refinery-produced gasoline. We also present the costs for the scenario 
that butanes would not need to be removed when ethanol is blended into 
wintertime gasoline. The costs for each control case are estimated by 
multiplying the change in volume for each gasoline blendstock, relative 
to the reference case, times its production, distribution and octane 
blending costs.
    The costs of these fuels changes are expressed two different ways. 
First, we express the cost of the program without the ethanol 
consumption subsidies in which the costs are based on the total 
accumulated cost of each of the fuels changes. The second way we 
express the cost is with the ethanol consumption subsidies included 
since the subsidized portion of the renewable fuels costs will be not 
be represented to the consumer in its fuels costs paid at the pump, but 
instead by being paid through the state and Federal tax revenues. For 
both cases we express the costs with and without butanes being removed 
due to changes in wintertime blending of ethanol. We evaluated the fuel 
costs using ranges in different assumptions to bound the many 
uncertainties in the cost analysis (see the DRIA for more discussion 
concerning the cost uncertainties).
    a. Cost without Ethanol Subsidies. Table VII.C.5.a-1 summarizes the 
costs without ethanol subsidies for each of the four control cases, 
including the cost for each aspect of the fuels changes, and the 
aggregated total and the per-gallon costs for all the fuel changes.\79\ 
This estimate of costs reflects the changes in gasoline that are 
occurring with the expanded use of ethanol, including the corresponding 
removal of MTBE. These costs include the labor, utility and other 
operating costs, fixed costs and the capital costs for all the fuel 
changes expected. We excluded Federal and state ethanol consumption 
subsidies

[[Page 55615]]

which avoids the transfer payments caused by these subsidies that would 
hide a portion of the program's costs.
---------------------------------------------------------------------------

    \79\ EPA typically assesses social benefits and costs of a 
rulemaking. However, this analysis is more limited in its scope by 
examining the average cost of production of ethanol and gasoline 
without accounting for the effects of farm subsidies that tend to 
distort the market price of agricultural commodities.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    Our analysis shows that when considering all the costs associated 
with these fuel changes resulting from the expanded use of subsidized 
ethanol that these various possible gasoline use scenarios will cost 
the U.S. $0.5 billion to around $1.6 billion in the year 2012. 
Expressed as per-gallon costs, these fuel changes would cost the U.S. 
0.3 to just over 1 cent per gallon of gasoline.
    b. Gasoline Costs Including Ethanol Consumption Tax Subsidies. 
Table VII.C.5.b-1 expresses the total and per-gallon gasoline costs for 
the four control scenarios with the Federal and state ethanol subsidies 
included. The Federal tax subsidy is 51 cents per gallon for each 
gallon of new ethanol blended into gasoline. The state tax subsidies 
apply in 5 states and range from 1.6 to 29 cents per gallon. The cost 
reduction to the fuel industry and consumers are estimated by 
multiplying the subsidy times the volume of new ethanol estimated to be 
used in the state. The costs are presented for the case that ethanol 
causes butanes to be withheld from the wintertime gasoline pool, and 
for the case that the blending of butanes remains unchanged.

    The cost including subsidies better represents gasoline's 
production cost as might be reflected to the fuel industry as a whole 
and to consumers ``at the pump'' because the Federal and state 
subsidies tends to hide a portion of the actual costs. Our analysis 
suggests that the fuel industry and consumers will see a 0.8 to 1.1 
cent per gallon decrease in the apparent cost of producing gasoline 
with these changes to gasoline.
    c. Cost Sensitivity Case Assuming $70 per Barrel Crude Oil. As 
described above, we analyzed a sensitivity analysis with the future 
price of crude oil remained at today's prices which is around $70 per 
barrel. This analysis was conducted by applying about a 1.4 
multiplication factor times the 2004 gasoline production costs, MTBE 
and alkylate feedstock costs and butane value. This factor was derived 
by examining the historical association between increasing wholesale 
gasoline prices with increasing crude oil prices. We did not adjust the 
distribution costs, any of the utility costs, octane value and ethanol 
prices based on the assumption that these would change much less and 
therefore we kept them the same as that used in the primary analysis. 
The cost results of the sensitivity analysis are provided with and 
without the ethanol consumption subsidies in Table VII.C.5.c-1.

    If crude oil stays priced at around $70 per barrel, the cost of 
these fuel changes would decrease significantly. In fact, we estimate 
that the 7.2 billion gallon ethanol case would result in a cost savings 
to the U.S. even if butanes are removed from the wintertime gasoline 
pool when ethanol is added. When considering the ethanol subsidies, the 
incentive to blend in ethanol becomes much stronger at today's crude 
oil prices likely causing a rapid increase in ethanol production 
volume.

VIII. What Are the Impacts of Increased Ethanol Use on Emissions and 
Air Quality?

    In this section, we evaluate the impact of increased production and 
use of renewable fuels on emissions and air quality in the U.S., 
particularly ethanol and biodiesel. In performing these analyses, we 
compare the emissions which would have occurred in the future if fuel 
quality had remained unchanged from pre-Act levels to those which will 
be required under the Energy Policy Act of 2005 (Energy Act or the 
Act). This approach differs from that traditionally taken in EPA 
regulatory impact analyses. Traditionally, we would have compared 
future emissions with and without the requirement of the Energy Act. 
However, as described in Section VI, we expect that total renewable 
fuel use in the U.S. in 2012 to exceed 7.5 billion gallons even in the 
absence of the RFS program. Thus, a traditional regulatory impact 
analysis would have shown no impact on emissions or air quality.
    Strictly speaking, if the same volume and types of renewable fuels 
are produced and used with and without the RFS program, the RFS program 
is having no impact on emissions or air quality. However, levels of 
renewable fuel use are increasing dramatically relative to both today 
and the recent past, with corresponding impacts on emissions and air 
quality. We believe that it is appropriate to evaluate these changes 
here, regardless of whether they are occurring due to economic forces 
or Energy Act requirements.
    In the process of estimating the impact of increased renewable fuel 
use, we also include the impact of reduced use of MTBE in gasoline. It 
is the increased production and use of ethanol which is facilitating 
the removal of MTBE while still producing the required volume of RFG 
which meets both commercial and EPA regulatory specifications. Because 
of this connection, we found it impractical to isolate the impact of 
increased ethanol use from the removal of MTBE.

A. Effect of Renewable Fuel Use on Emissions

1. Emissions From Gasoline Fueled Motor Vehicles and Equipment
    Several models of the impact of gasoline quality on motor vehicle 
emissions have been developed since the early 1990's. We evaluated 
these models and selected those which were based on the most 
comprehensive set of emissions data and developed using the most 
advanced statistical tools for this analysis. Still, as will be 
described below, significant uncertainty still exists as to the effect 
of these gasoline components on emissions from both motor vehicle and 
nonroad equipment, particularly from the latest models equipped with 
the most advanced emission controls. Pending adequate funding, we plan 
to conduct significant vehicle and equipment testing over the next 
several years to improve our estimates of the impact of these additives 
and other gasoline properties on emissions. The results of this testing 
will not be available for inclusion in the analyses supporting this 
rulemaking. We hope that the results from these test programs will be 
available for reference in the future evaluations of the emission and 
air quality impacts of U.S. fuel programs required by the Act.\80\

    The remainder of this sub-section is divided into three parts. The 
first evaluates the impact of increased ethanol use and decreased MTBE 
use on gasoline quality. The second evaluates the impact of increased 
ethanol use and decreased MTBE use on motor vehicle emissions. The 
third evaluates the impact of increased ethanol use and decreased MTBE 
use on nonroad equipment emissions.
    a. Gasoline Fuel Quality. For this proposal, we estimate the impact 
of ethanol use on gasoline quality using fuel survey data obtained by 
Alliance of Automobile Manufacturers (AAM) from 2001-2005.\81\ We 
estimate the impact of removing MTBE from gasoline based on refinery 
modeling performed in support of the RFG rulemaking. We plan to update 
these estimates for the FRM using refinery modeling which is currently 
underway. In general, as shown in Table VIII.A.1.a-1, adding ethanol to 
gasoline is expected to reduce levels of aromatics and olefins in 
conventional gasoline, as well as reduce mid and high distillation 
temperatures (e.g., T50 and T90). RVP is expected to increase, as most 
areas of the country grant ethanol blends a 1.0 RVP waiver of the 
applicable RVP standards in the summer. With the exception of RVP, the 
effect of removing MTBE results in essentially the opposite impacts. 
Please see Chapter 2 of the DRIA for a detailed description of the 
methodologies used and the specific changes in projected fuel quality.
---------------------------------------------------------------------------

    \81\ Alliance of Automobile Manufacturers North American Fuel 
Survey 2005. For the final rule, we intend to supplement this 
empirical approach with the results of refinery modeling which might 
better capture all of the effects of ethanol blending on gasoline 
quality.

    The effect of adding ethanol and removing MTBE on the quality of 
RFG is expected to very limited. RFG must meet stringent VOC, 
NO<INF>X</INF> and toxics performance standards. Thus, the natural 
effects of MTBE and ethanol blending on gasoline must often be 
addressed through further refining. The largest differences are 
expected to exist in terms of the distillation temperatures, due to the 
relatively low boiling point of ethanol. Other fuel parameters are 
expected to be very similar. For this analysis we have assumed no 
changes to fuel parameters other than ethanol and MTBE content for RFG.
    b. Emissions from Motor Vehicles. We use the EPA Predictive Models 
to estimate the impact of gasoline fuel quality on exhaust VOC and 
NO<INF>X</INF> emissions from motor vehicles. These models were 
developed in 2000, in support of EPA's response to California's request 
for a waiver of the RFG oxygen mandate. These models represent a 
significant update of the EPA Complex Model. However, they are still 
based on emission data from Tier 0 vehicles (roughly equivalent to 1990 
model year vehicles). We based our estimates of the impact of fuel 
quality on CO emissions on the EPA MOBILE6.2 model. We base our 
estimates of the impact of fuel quality on exhaust toxic emissions 
(benzene, formaldehyde, acetaldehyde, and 1,3-butadiene) primarily on 
the MOBILE6.2 model, updated to reflect the effect of fuel quality on 
exhaust VOC emissions per the EPA Predictive Models. Very limited data 
are available on the effect of gasoline quality on PM emissions. 
Therefore, the effect of increased ethanol use on PM emissions can only 
be qualitatively discussed.
    In responding to California's request for a waiver of the RFG 
oxygen mandate in 2000, we found that both very limited and conflicting 
data were available on the effect of fuel quality on exhaust emissions 
from Tier 1 and later vehicles.\82\ Thus, we assumed at the time that 
changes to gasoline quality would not affect VOC, CO and NO<INF>X</INF> 
exhaust emissions from these vehicles. Very little additional data has 
been collected since that time on which to modify this assumption. 
Consequently, for our primary analysis for today's proposal we have 
maintained the assumption that changes to gasoline do not affect 
exhaust emissions from Tier 1 and later technology vehicles.
---------------------------------------------------------------------------

    \82\ The one exception was the impact of sulfur on emissions 
from these later vehicles, which is not an issue here due to the 
fact that renewable fuel use is not expected to change sulfur levels 
significantly.
---------------------------------------------------------------------------

    There is one recent study by the Coordinating Research Council 
(CRC) which assessed the impact of ethanol and two other fuel 
properties on emissions from twelve 2000-2004 model year vehicles (CRC 
study E-67). The results of this program indicate that emissions from 
these late model year vehicles may be at least as sensitive to changes 
to these three fuel properties as Tier 0 vehicles on a percentage 
basis.\83\ However, because this study is the first of its kind and not 
all relevant fuel properties have yet been studied, in our primary 
analysis we continue to assume that exhaust emissions from Tier 1 and 
later vehicles are not sensitive to fuel quality. Based on the 
indications of the CRC E-67 study, we also conducted a sensitivity 
analysis where the exhaust VOC and NO<INF>X</INF> emission impacts for 
all vehicles were assumed to be as sensitive to fuel quality as Tier 0 
vehicles (i.e., as indicated by the EPA Predictive Models).
---------------------------------------------------------------------------

    \83\ The VOC and NO<INF>X</INF> emissions from the 2000-2004 
model year vehicles are an order of magnitude lower than those from 
the Tier 0 vehicles used to develop the EPA Complex and Predictive 
Models. Thus, a similar impact of a fuel parameter in terms of 
percentage means a much smaller impact in terms of absolute 
emissions.
---------------------------------------------------------------------------

    We base our estimates of fuel quality on non-exhaust VOC and 
benzene emissions on the EPA MOBILE6.2 model. The one exception to this 
is the effect of ethanol on permeation emissions through plastic fuel 
tanks and elastomers used in fuel line connections. Recent testing has 
shown that ethanol increases permeation emissions, both by permeating 
itself and increasing the permeation of other gasoline components. This 
effect was included in EPA's analysis of California's most recent 
request for a waiver of the RFG oxygen requirement, but is not in 
MOBILE6.2.\84\ Therefore, we have added the effect of ethanol on 
permeation emissions to MOBILE6.2's estimate of non-exhaust VOC 
emissions in assessing the impact of gasoline quality on these 
emissions.
---------------------------------------------------------------------------

    \84\ For more information on California's request for a waiver 
of the RFG oxygen mandate and the Decision Document for EPA's 
response, see http://www.epa.gov/otaq/rfg_regs.htm#waiver.
---------------------------------------------------------------------------

    No models are available which address the impact of gasoline 
quality on PM emissions. Very limited data indicate that ethanol 
blending might reduce exhaust PM emissions under very cold weather 
conditions (e.g., -20 F to 0 F). Very limited testing at warmer 
temperatures (e.g., 20 F to 75 F) shows no definite trend in PM 
emissions with oxygen content. Thus, for now, no quantitative estimates 
can be made regarding the effect of ethanol use on direct PM emissions.
    Table VIII.A.1.b-1 presents the average per vehicle (2012 fleet) 
emission impacts of three types of RFG: Non-oxygenated, a typical MTBE 
RFG as has been marketed in the Gulf Coast, and a typical ethanol RFG 
which has been marketed in the Midwest.

\a\ Average per vehicle effects for the 2012 fleet during summer conditions.

    As can be seen, the oxygenated RFG blends are predicted to produce 
a greater reduction in exhaust VOC and CO emissions than 9 RVP 
conventional gasoline, but a larger increase in NO<INF>X</INF> 
emissions. This comparison assumes that all gasoline meets EPA's Tier 2 
gasoline sulfur standard of 30 ppm. Prior to this program, RFG 
contained less sulfur than conventional gasoline and produced less 
NO<INF>X</INF> emissions. Non-exhaust VOC emissions with the exception 
of permeation are roughly the same due to the fact that the RVP level 
of the three blends is the same. However, the increased permeation 
emissions associated with ethanol reduces the overall effectiveness of 
ethanol RFG.
    An increase in ethanol use will also impact emissions of air 
toxics. We evaluated effects on four air toxics affected by fuel 
parameter changes in the Complex Model-benzene, formaldehyde, 
acetaldehyde and 1,3-butadiene. The most notable effect on toxic 
emissions in percentage terms is the increase in acetaldehyde with the 
use of ethanol. Acetaldehyde emissions more than double. However, as 
will be seen below, base acetaldehyde emissions are low relative to the 
other toxics. Thus, the absolute increase in total emissions of these 
four air toxics is still relatively low.
    Table VIII.A.1.b-2 presents the effect of blending either MTBE or 
ethanol into conventional gasoline while matching octane.

\c\ The first figure shown applies to normal emitters; the second applies to high emitters.

    As was the case with the RFG blends, the two oxygenated blends both 
reduce exhaust VOC and CO emissions, but increase NO<INF>X</INF> 
emissions. The MTBE blend does not increase non-exhaust VOC emissions, 
but the ethanol blend does due to the commonly granted waiver of the 
RVP standard. Both blends have lower exhaust benzene and 1,3-butadiene 
emissions. As above, ethanol increases non-exhaust benzene and 
acetaldehyde emissions.
    The exhaust emission effects shown above for VOC and NO<INF>X</INF> 
emissions only apply to Tier 0 vehicles in our primary analysis. For 
example, MOBILE6.2 estimates that 34% of exhaust VOC emissions and 16% 
of NO<INF>X</INF> emissions from gasoline vehicles in 2012 come from 
Tier 0 vehicles. In the sensitivity analysis, these effects are 
extended to all gasoline vehicles. The effect of RVP on non-exhaust VOC 
emissions is temperature dependent. The figures shown above are based 
on the distribution of temperatures occurring across the U.S. in July.
    c. Nonroad Equipment. To estimate the effect of gasoline quality on 
emissions from nonroad equipment, we used EPA's NONROAD emission model. 
We used the 2005 version of this model, NONROAD2005, which includes the 
effect of ethanol on permeation emissions from most nonroad equipment.

[[Page 55619]]

    Only sulfur and oxygen content affect exhaust VOC, CO and 
NO<INF>X</INF> emissions in NONROAD. Since sulfur level is assumed to 
remain constant, the only difference in exhaust emissions between 
conventional and reformulated gasoline is due to oxygen content. Table 
VIII.A.1.c-1 shows the effect of adding 11 volume percent MTBE or 10 
volume percent ethanol to non-oxygenated gasoline on these emissions.

    As can be seen, higher oxygen content reduces exhaust VOC and CO 
emissions significantly, but also increases NO<INF>X</INF> emissions. 
However, NO<INF>X</INF> emissions from these engines tend to be fairly 
low to start with, given the fact that these engines run much richer 
than stoichiometric. Thus, a large percentage increase of a relative 
low base value can be a relatively small increase in absolute terms.
    Evaporative emissions from nonroad equipment are impacted by only 
RVP, and permeation by ethanol content. Both the RVP increase due to 
blending of ethanol and its permeation effect cause non-exhaust VOC 
emissions to increase with the use of ethanol in nonroad equipment. The 
26 percent effect represents the average impact across the U.S. in July 
for both 2-stroke and 4-stroke equipment. We updated the NONROAD2005 
hose permeation emission factors for small spark-ignition engines and 
recreational marine watercraft to reflect the use of ethanol.
    For nonroad toxics emissions, we base our estimates of the impact 
of fuel quality on the fraction of exhaust VOC emissions represented by 
each toxic on MOBILE6.2 (i.e., the same effects predicted for onroad 
vehicles). The National Mobile Inventory Model (NMIM) contains 
estimates of the fraction of VOC emissions represented by the various 
air toxics based on oxygenate type (none, MTBE or ethanol). However, 
estimates for nonroad gasoline engines running on different fuel types 
are limited, making it difficult to accurately model the impacts of 
changes in fuel quality. In the recent NPRM addressing mobile air toxic 
emissions, EPA replaced the toxic-related fuel effects contained in 
NMIM with those from MOBILE6.2 for onroad vehicles.\85\ We follow the 
same methodology here. Future testing could significantly alter these 
emission impact estimates.

2. Diesel Fuel Quality: Biodiesel
    EPA assessed the impact of biodiesel fuel on emissions in 2002 and 
published a draft report summarizing the results.\86\ At that time, 
most of the data available was for pre-1998 model year onroad diesel 
engines. The results are summarized in Table VIII.A.2-1. As shown, it 
indicated that biodiesel tended to reduce emissions of VOC, CO and PM. 
The NO<INF>X</INF> emission effect was more variable, showing a very 
small increase on average.

    We collected relevant engine and vehicle emission test data 
developed since the time of the 2002 study. The results of our analysis 
of this data are also shown in Table VIII.A.2-1. There, we show the 
average change in the emissions of each pollutant across all the 
engines or vehicles tested, as well as the range of effects found for 
each engine or vehicle. As can be seen, the variability in the emission 
effects is quite large, but the results of the more recent testing 
generally corroborate the findings of the 2002 study. Refer to DRIA 
Tables 3.1-15 and 3.1-16, and their corresponding discussion, for more 
detail on the data in the above table.
    Overall, data indicating the effect of biodiesel on emissions is 
still quite limited. The emission effects also appear to be dependent 
on the load and speed of the engine (or driving cycle and vehicle type 
in the case of vehicle testing). However, the data are too limited to 
determine the specific way in which this occurs. Also, with the 
implementation of stringent NO<INF>X</INF> and PM emission standards to 
onroad and nonroad diesels in the 2007-2010 timeframe, any effect on a 
percentage basis will rapidly decrease in magnitude on a mass basis as 
base emission inventory level decreases. As additional testing is 
performed over the next several years we will update this assessment.
3. Renewable Fuel Production and Distribution
    The primary impact of renewable fuel production and distribution 
regards ethanol, since it is expected to be the

[[Page 55620]]

predominant renewable fuel used in the foreseeable future. We 
approximate the impact of increased ethanol and biodiesel production, 
including corn and soy farming, on emissions based on DOE's GREET 
model, version 1.6. We also include emissions related to distributing 
the renewable fuels and take credit for reduced emissions related to 
distributing displaced gasoline and diesel fuel. These emissions are 
summarized in Table VIII.A.3-1.

a Includes credit for reduced distribution of gasoline and diesel fuel.

    At the same time, areas with refineries might experience reduced 
emissions, not necessarily relative to current emission levels, but 
relative to those which would have occurred in the future had renewable 
fuel use not risen. However, to the degree that increased renewable 
fuel use reduces imports of gasoline and diesel fuel, as opposed to the 
domestic production of these fuels, these reduced refinery emissions 
will occur overseas and not in the U.S.
    Similarly, areas with MTBE production facilities might experience 
reduced emissions from these plants as they cease producing MTBE. 
However, many of these plants may be converted to produce other 
gasoline blendstocks, such as iso-octane or alkylate. In this case, 
their emissions are not likely to change substantially.

B. Impact on Emission Inventories

    We use the NMIM to estimate emissions under the various ethanol 
scenarios on a county by county basis. NMIM basically runs MOBILE6.2 
and NONROAD2005 with county-specific inputs pertaining to fuel quality, 
ambient conditions, levels of onroad vehicle VMT and nonroad equipment 
usage, etc. We ran NMIM for two months, July and January. We estimate 
annual emission inventories by summing the two monthly inventories and 
multiplying by six.
    As described above, we removed the effect of gasoline fuel quality 
on exhaust VOC and NO<INF>X</INF> emissions from the onroad motor 
vehicle inventories which are embedded in MOBILE6.2. We then applied 
the exhaust emission effects from the EPA Predictive Models. In our 
primary analysis, we only applied these EPA Predictive Model effects to 
exhaust VOC and NO<INF>X</INF> emissions from Tier 0 vehicles. In a 
sensitivity case, we applied them to exhaust VOC and NO<INF>X</INF> 
emissions from all vehicles. Regarding the effect of fuel quality on 
emissions of four air toxics from nonroad equipment (in terms of their 
fraction of VOC emissions), in all cases we replaced the fuel effects 
contained in NMIM with those for motor vehicles contained in MOBILE6.2. 
The projected emission inventories for the primary analysis are 
presented first, followed by those for the sensitivity analysis.
1. Primary Analysis
    The national emission inventories for VOC, CO and NO<INF>X</INF> in 
2012 with current fuels (i.e., ``reference fuel'') are summarized in 
Table VIII.B.1-1. Also shown are the changes in emissions projected for 
the two levels of ethanol use (i.e., ``control cases'') described in 
Section VI and the two different cases for ethanol use in RFG.

----------------------------------------------------------------------------------------------------------------

    Both VOC and NO<INF>X</INF> emissions are projected to increase 
with increased use of ethanol. However, the increases are small, 
generally less than 2 percent. Emissions of formaldehyde are also 
projected to increase slightly, on the order of 1-3 percent. Emissions 
of 1,3-butadiene and CO are projected to decrease by about 1-4 percent. 
Benzene emissions are projected to decrease by 2-6 percent. The largest 
change is in acetaldehyde emissions, an increase of 25-48 percent, as 
acetaldehyde is a partial combustion product of ethanol.
    CO also participates in forming ozone, much like VOCs. Generally, 
CO is 15-50 times less reactive than typical VOC. Still, the reduction 
in CO emissions is roughly 20-140 times the increase in VOC emissions 
in the four scenarios. Thus, the projected reduction in CO emissions is 
important from an ozone perspective. However, as described above, the 
methodology for projecting the effect of ethanol use on CO emissions is 
inconsistent with that for exhaust VOC and NO<INF>X</INF> emissions. 
Thus, comparisons between changes in VOC and CO emissions are 
particularly uncertain.
    In addition to these changes in emissions due to ethanol use, 
biodiesel use is expected to have a minor impact on diesel emissions. 
Table VIII.B.1-2 shows the expected emission reductions associated with 
an increase in biodiesel fuel use from the reference case of 28 million 
gallons in 2012 to approximately 300 million gallons per year in 2012. 
This represents an increase from 0.06 to 0.6 percent of onroad diesel 
fuel consumption. In terms of a 20 percent biodiesel blend

[[Page 55621]]

(B20), it represents an increase from 0.3 to 3.2 percent of onroad 
diesel fuel consumption.

    As can be seen, the emission impacts due to biodiesel use are 
roughly two orders of magnitude smaller than those due to ethanol use.
    There will also be some increases in emissions due to ethanol and 
biodiesel production. Table VIII.B.1-3 shows estimates of annual 
emissions expected to occur nationwide due to increased production of 
ethanol. These estimates include a reduction in emissions related to 
the distribution of the displaced gasoline.

    As can be seen, the potential increases in emissions from ethanol 
production and transportation are of the same order of magnitude as 
those from ethanol use, with the exception of CO emissions. The vast 
majority of these emissions are related to farming and ethanol 
production. Both farms and ethanol plants are generally located in 
ozone attainment areas.
    Table VIII.B.1-4 shows estimates of annual emissions expected to 
occur nationwide due to increased production of biodiesel. These 
estimates include a reduction in emissions related to the distribution 
of the displaced diesel fuel.

    The potential emission increases related to biodiesel production 
and distribution are generally much smaller, with the possible 
exception of VOC emissions. Again, these emissions are generally 
expected to be in ozone attainment areas.
2. Sensitivity Analysis
    The national emission inventories for VOC and NO<INF>X</INF> in 
2012 with current fuels are summarized in Table VIII.B.2-1. Here, the 
emission effects contained in the EPA Predictive Models are assumed to 
apply to all vehicles, not just Tier 0 vehicles. Also shown are the 
changes in emissions projected for the two cases for future ethanol 
volume and the two cases of ethanol use in RFG. CO emissions are the 
same as in the primary analysis, as they are not affected by the EPA 
Predictive Models.

    The overall VOC and NO<INF>X</INF> emission impacts of the various 
ethanol use scenarios change to some degree when all motor vehicles are 
assumed to be sensitive to fuel ethanol content. The increase in VOC 
emissions either decreases substantially or turns into a net decrease 
due to a greater reduction in exhaust VOC emissions from onroad 
vehicles. However, the increase in NO<INF>X</INF> emissions gets 
larger, as more vehicles are assumed to be affected by ethanol. 
Emissions of the four air toxics generally decrease slightly, due to 
the greater reduction in exhaust VOC emissions.
3. Local and Regional VOC and NO<INF>X</INF> Emission Impacts in July
    We also estimate the percentage change in VOC and NO<INF>X</INF> 
emissions from gasoline fueled motor vehicles and equipment in those 
areas which actually experienced a significant change in ethanol use. 
Specifically, we focused on areas where the market share of ethanol 
blends was projected to change by 50 percent or more. We also focused 
on summertime emissions, as these are most relevant to ozone formation. 
Finally, we developed separately estimates for: (1) RFG areas, 
including the state of California and the portions of Arizona where 
their CBG fuel programs apply, (2) low RVP areas (i.e., RVP standards 
less than 9.0 RVP, and (3) areas with a 9.0 RVP standard. This set of 
groupings helps to highlight the emissions impact of increased ethanol 
use in those areas where emission control is most important.
    Table VIII.B.3-1 presents our primary estimates of the percentage 
change in VOC and NO<INF>X</INF> emission inventories for these three 
types of areas. While ethanol use is going up in the vast majority of 
the nation, ethanol use in RFG areas under the ``Minimum Use in RFG'' 
scenarios is actually decreasing compared to the 2012 reference case. 
This is important to note in order to understand the changes in 
emissions indicated.

    As expected, increased ethanol use tends to increase NO<INF>X</INF> 
emissions. The increase in low RVP and other areas is greater than in 
RFG areas, since the RFG in the RFG areas included in this analysis all 
contained MTBE. Also, increased ethanol use tends to increase VOC 
emissions, indicating that the increase in non-exhaust VOC emissions 
exceeds the reduction in exhaust VOC emissions. This effect is muted 
with RFG due to the absence of an RVP waiver for ethanol blends. The 
reader is referred to Chapter 2 of the DRIA for discussion of how 
ethanol levels will change at the state-level.

    Directionally, the changes in VOC and NO<INF>X</INF> emissions in 
the various areas are consistent with those from our primary analysis. 
The main difference is that the increases in VOC emissions are smaller, 
due to more vehicles experiencing a reduction in exhaust VOC emissions, 
and the increases in NO<INF>X</INF> emissions are larger.

C. Impact on Air Quality

    We estimate the impact of increased ethanol use on the ambient 
concentrations of two pollutants: ozone and PM. Quantitative estimates 
are made for ozone, while only qualitative estimates can be made 
currently for ambient PM. These impacts are described below.
1. Impact of 7.2 Billion Gallon Ethanol Use on Ozone
    We use a metamodeling tool developed at EPA, the ozone response 
surface metamodel (Ozone RSM), to estimate the effects of the projected 
changes in emissions from gasoline vehicles and equipment for the 7.2 
billion gallon ethanol use case. The changes in diesel emissions are 
negligible in comparison. We did not include the estimated changes in 
emissions from renewable fuel production and distribution, because of 
their more approximate nature. Their geographical concentration also 
makes it more difficult to simulate with the Ozone RSM.
    The Ozone RSM was created using multiple runs of the Comprehensive 
Air Quality Model with Extensions (CAMx). Base and proposed control 
CAMx metamodeling was completed for the year 2015 over a modeling 
domain that includes all or part of 37 Eastern U.S. states, plus the 
District of Columbia. For more information on the Ozone RSM, please see 
the Chapter 5 of the DRIA for this proposal.
    The Ozone RSM limits the number of geographically distinct changes 
in VOC and NO<INF>X</INF> emissions which can be simulated. As a 
result, we could not apply distinct changes in emissions for each 
county. Therefore, two separate runs were made with different VOC and 
NO<INF>X</INF> emissions reductions. We then selected the ozone impacts 
from the various runs which best matched the VOC and NO<INF>X</INF> 
emission reductions for that county. This models the impact of local 
emissions reasonably well, but loses some accuracy with respect to 
ozone transport. No ozone impact was assumed for areas which did not 
experience a significant change in ethanol use. The predicted ozone 
impacts of increased ethanol use for those areas where ethanol use is 
projected to change by more than a 50% market share are summarized in 
Table VIII.C.1-1. As shown in Table 5.1-2 of the DRIA, national average 
impacts (based on the 37-state area modeled) which include those areas 
where no change in ethanol use is occurring are considerably smaller.

b Only for those areas experiencing a change in ethanol blend market share of at least 50 percent.

    As can be seen, ozone levels generally increase to a small degree 
with increased ethanol use. This is likely due to the projected 
increases in both VOC and NO<INF>X</INF> emissions. Some areas do see a 
small decrease in ozone levels. In our primary analysis, where exhaust 
emissions from Tier 1 and later onroad vehicles are assumed to be 
unaffected

[[Page 55624]]

by ethanol use, the population-weighted increase in ambient ozone 
levels in those areas where ethanol use changed significantly is 0.129-
0.134 ppb. Since the 8-hour ambient ozone standard is 80 ppb, this 
increase represents about 0.16 percent of the standard, a very small 
percentage.
    In our sensitivity analysis, where exhaust emissions from Tier 1 
and later onroad vehicles are assumed to respond to ethanol like Tier 0 
vehicles, the population-weighted increase in ambient ozone levels is 
roughly twice as high, or 0.250-0.268 ppb. This increase represents 
about 0.32 percent of the standard.
    There are a number of important caveats concerning these estimates. 
First, the emission effects of adding ethanol to gasoline are based on 
extremely limited data for recent vehicles and equipment. Second, the 
Ozone RSM does not account for changes in CO emissions. As shown above, 
ethanol use should reduce CO emissions significantly, directionally 
reducing ambient ozone levels in those areas where ozone formation is 
VOC-limited. (Ozone levels in areas which are NO<INF>X</INF>-limited 
are unlikely to be affected by a change in CO emissions.) The Ozone RSM 
also does not account for changes in VOC reactivity. With additional 
ethanol use, the ethanol content of VOC should increase. Ethanol is 
less reactive than the average VOC. Therefore, this change should also 
reduce ambient ozone levels in a way not addressed by the Ozone RSM, 
again in those areas where ozone formation is predominantly VOC-
limited.
    Moving to health effects, exposure to ozone has been linked to a 
variety of respiratory effects including premature mortality, hospital 
admissions and illnesses resulting in school absences. Ozone can also 
adversely affect the agricultural and forestry sectors by decreasing 
yields of crops and forests. Although the health and welfare impacts of 
changes in ambient ozone levels are typically quantified in regulatory 
impact analyses, we do not evaluate them for this analysis. On average, 
the changes in ambient ozone levels shown above are small and would be 
even smaller if changes in CO emissions and VOC reactivity were taken 
into account. The increase in ozone would likely lead to negligible 
monetized impacts. We therefore do not estimate and monetize ozone 
health impacts for the changes in renewable use due to the small 
magnitude of this change, and the uncertainty present in the air 
quality modeling conducted here, as well as the uncertainty in the 
underlying emission effects themselves discussed earlier.
2. Particulate Matter
    Ambient PM can come from two distinct sources. First, PM can be 
directly emitted into the atmosphere. Second, PM can be formed in the 
atmosphere from gaseous pollutants. Gasoline-fueled vehicles and 
equipment contribute to ambient PM concentrations in both ways.
    As described above, we are not currently able to predict the impact 
of fuel quality on direct PM emissions from gasoline-fueled vehicles or 
equipment. Therefore, we are unable at this time to project the effect 
that increased ethanol use will have on levels of directly emitted PM 
in the atmosphere.
    PM can also be formed in the atmosphere (termed secondary PM here) 
from several gaseous pollutants emitted by gasoline-fueled vehicles and 
equipment. Sulfur dioxide emissions contribute to ambient sulfate PM. 
NO<INF>X</INF> emissions contribute to ambient nitrate PM. VOC 
emissions contribute to ambient organic PM, particularly the portion of 
this PM comprised of organic carbon. Increased ethanol use is not 
expected to change gasoline sulfur levels, so emissions of sulfur 
dioxide and any resultant ambient concentrations of sulfate PM are not 
expected to change. Increased ethanol use is expected to increase 
NO<INF>X</INF> emissions, as described above. Thus, the possibility 
exists that ambient nitrate PM levels could increase. Increased ethanol 
is generally expected to increase VOC emissions, which could also 
impact the formation of secondary organic PM. However, some VOC 
emissions, namely exhaust VOC emissions, are expected to decrease, 
while non-exhaust VOC emissions are expected to increase and the impact 
on PM is a function of the type of VOC emissions.
    The formation of secondary organic PM is very complex, due in part 
to the wide variety of VOCs emitted into the atmosphere. Whether or not 
a specific gaseous VOC reacts to form PM in the atmosphere depends on 
the types of reactions that VOC undergoes, which in turn can depend on 
other pollutants present, such as ozone, NO<INF>X</INF> and other 
reactive compounds. The relative mass of secondary PM formed per mass 
of gaseous VOC emitted can also depend on the concentration of the 
gaseous VOC and the organic PM in the atmosphere. Most of the secondary 
organic PM exists in a continually changing equilibrium between the 
gaseous and PM phases. Both the rates of these reactions and the 
gaseous-PM equilibria depend on temperature, so seasonal differences 
can be expected.
    Recent smog chamber studies have indicated that gaseous aromatic 
VOCs can form secondary PM under certain conditions. These compounds 
comprise a greater fraction of exhaust VOC emissions than non-exhaust 
VOC emissions, as non-exhaust VOC emissions are dominated by VOCs with 
relatively high vapor pressures. Aromatic VOCs tend to have lower vapor 
pressures. As increased ethanol use is expected to reduce exhaust VOC 
emissions, emissions of aromatic VOCs should also decrease. In 
addition, refiners are expected to reduce the aromatic content of 
gasoline by 5 volume percentage points as ethanol is blended into 
gasoline. Emissions of aromatic VOCs should decrease with lower 
concentrations of aromatics in gasoline. Thus, emissions of gaseous 
aromatic VOCs could decrease for both reasons.
    Overall, we expect that the decrease in secondary organic PM is 
likely to exceed the increase in secondary nitrate PM. In 1999, 
NO<INF>X</INF> emissions from gasoline-fueled vehicles and equipment 
comprised about 20% of national NO<INF>X</INF> emissions from all 
sources. In contrast, gasoline-fueled vehicles and equipment comprised 
over 60% of all national gaseous aromatic VOC emissions. The percentage 
increase in national NO<INF>X</INF> emissions due to increased ethanol 
use should be smaller than the percentage decrease in national 
emissions of gaseous aromatics. Finally, in most urban areas, ambient 
levels of secondary organic PM exceed those of secondary nitrate PM. 
Thus, directionally, we expect a net reduction in ambient PM levels due 
to increased ethanol use. However, we are unable to quantify this 
reduction at this time.
    EPA currently utilizes the CMAQ model to predict ambient levels of 
PM as a function of gaseous and PM emissions. This model includes 
mechanisms to predict the formation of nitrate PM from NO<INF>X</INF> 
emissions. However, it does not currently include any mechanisms 
addressing the formation of secondary organic PM. EPA is currently 
developing a model of secondary organic PM from gaseous toluene 
emissions. We plan to incorporate this mechanism into the CMAQ model in 
2007. The impact of other aromatic compounds will be added as further 
research clarifies their role in secondary organic PM formation. 
Therefore, we expect to be able to quantitatively estimate the impact 
of decreased toluene emissions and increased NO<INF>X</INF> emissions 
due to

[[Page 55625]]

increased ethanol use as part of future analyses of U.S. fuel 
requirements required by the Act.

IX. Impacts on Fossil Fuel Consumption and Related Implications

    Renewable fuels have been of significant interest for many years 
due to their ability to displace fossil fuels, which have often been 
targeted as primary contributors to emissions of greenhouse gases such 
as carbon dioxide and national energy concerns such as dependence on 
foreign sources of petroleum. Because significantly more renewable fuel 
is expected to be consumed over the next few years than has been 
consumed in the past, there is increased interest in the degree to 
which their increased use will impact greenhouse gas emissions and 
fossil fuel consumption.
    Based on our analysis, we estimate that increases in the use of 
renewable fuels will reduce fossil fuel consumption and GHG emissions 
as shown in Table IX-1 in 2012. The results represent the percent 
reduction in total transportation sector emissions and energy use. The 
ranges result from different cases evaluated of the amount of renewable 
fuel (7.5 billion gallons versus 9.9 billion gallons) that will 
actually be produced in 2012.

    This section provides a summary of our analysis of the fossil fuel 
impacts of the RFS rule.

A. Lifecycle Modeling

    Although the use of renewable fuels in the transportation sector 
directly displaces some petroleum consumed as motor vehicle fuel, this 
displacement of petroleum is in fact only one aspect of the overall 
impact of renewable fuels on fossil fuel use. Fossil fuels are also 
used in producing and transporting renewable feedstocks such as plants 
or animal byproducts, in converting the renewable feedstocks into 
renewable fuel, and in transporting and blending the renewable fuels 
for consumption as motor vehicle fuel. To estimate the true impacts of 
increases in renewable fuels on fossil fuel use, modelers attempt to 
take many or all these steps into account. Similarly, energy is used 
and GHGs emitted in the pumping of oil, transporting the oil to the 
refinery, refining the crude oil into finished transportation fuel, 
transporting the refined gasoline or diesel fuel to the consumer and 
then burning the fuel in the vehicle. Such analyses are termed 
lifecycle or well-to-wheels analyses.
    A variety of approaches are available to conduct lifecycle 
analysis. This variety largely reflects different assumptions about (1) 
the boundary conditions and (2) the estimates of input factors. The 
boundary conditions determine the scope of the analysis. For example, a 
lifecycle analysis could include energy required to make farm equipment 
as part of the estimate of energy required to grow corn. The agency 
chose a lifecycle analytic boundary that encompasses the fuel-cycle and 
does not include the example used above. Differing estimates on input 
factors (e.g. amount of fertilizer to grow corn) can also affect the 
results of the lifecycle analysis.
    For this proposed rulemaking, we have made use of a fuel-cycle 
model, GREET,\87\ developed at Argonne National Laboratory (ANL) under 
the sponsorship of the U.S. Department of Energy's Office of Energy 
Efficiency and Renewable Energy (EERE). GREET has been under 
development for several years and has undergone extensive peer review 
through multiple updates. Of the available sources of information on 
lifecycle analyses of energy consumed and emissions generated, we 
believe that GREET offers the most comprehensive treatment of the 
transportation sector. For instance, GREET provides lifecycle 
assessments for ethanol made from corn and cellulosic materials, 
biodiesel made from soybean oil, and petroleum-based gasoline and 
diesel fuel. Thus GREET provides a means for calculating the relative 
greenhouse gas (GHG) and petroleum impacts of renewable fuels that 
displace conventional motor vehicle fuels. For this proposal, we used 
version 1.7 of the GREET model, with a few modifications to its input 
assumptions as described in more detail below.
---------------------------------------------------------------------------

    \87\ Greenhouse gases, Regulated Emissions, and Energy use in 
Transportation.
---------------------------------------------------------------------------

    We do not believe that it would be appropriate at this time to base 
the regulatory provisions for this rule on lifecycle modeling, as 
described in more detail in Section III.B.4. Although the GREET model 
does provide a peer-reviewed source for lifecycle modeling, a consensus 
on all the assumptions, including point estimates, that are used as 
inputs into that model does not exist.\88\ Also, given the short 
timeframe available for the development of this proposal, we have not 
had the opportunity to initiate the type of public dialogue on 
lifecycle modeling that would be necessary before such analyses could 
be incorporated into a regulatory framework. We have therefore chosen 
to use lifecycle modeling only as a means to estimate the impacts of 
the increased use of renewable fuel.
---------------------------------------------------------------------------

    \88\ See Chapter 6.1.2 of the RIA for further discussion of 
input assumptions used for the GREET modeling. Also see IX.A.2 of 
this preamble section for a discussion about the differing 
estimates.
---------------------------------------------------------------------------

    In addition to the GREET model tool, EPA has also developed a 
lifecycle modeling tool that is specific to individual fuel producers. 
This FUEL-CO2 model is intended to help fuel producers estimate the 
lifecycle greenhouse gas emissions and fossil energy use for all stages 
in the development of their specific fuel. EPA will evaluate whether 
the FUEL-CO2 model would be an appropriate tool for fuel providers who 
wish to demonstrate their actual reductions in greenhouse gas emissions 
and fossil energy use. This may also be the best way for ethanol 
producers to quantify the benefits of their renewable process energy 
use when qualifying corn ethanol as cellulosic biomass ethanol (an 
option for ethanol producers, stipulated in the Act).

[[Page 55626]]

1. Modifications to GREET Assumptions
    GREET is subject to periodic updates by ANL, each of which results 
in some changes to the inputs and assumptions that form the basis for 
the lifecycle estimates of emissions generated and energy consumed. 
These updates generally focus on those input values for those fuels or 
vehicle technologies that are the focus of ANL at the time. As a result 
there are a variety of other inputs related to ethanol and biodiesel 
that have not been updated in some time. In the context of the RFS 
program, we determined that some of the GREET input values that were 
either based on outdated information or did not appropriately reflect 
market conditions under a renewable fuels mandate should be examined 
more closely, and updated if necessary.
    In the timeframe available for developing this proposal, we chose 
to concentrate our efforts on those GREET input values for ethanol that 
had significant influence on the lifecycle emissions or energy 
estimates and that were likely to be based on outdated information. We 
reviewed the input values only for ethanol made from corn, since this 
particular renewable fuel is likely to continue to dominate the 
renewable fuel pool through at least 2012. For cellulosic ethanol and 
biodiesel the GREET default values were used in this proposal. However, 
we have also initiated a contract with ANL to investigate a wider 
variety of GREET input values, including those associated with the 
following fuel/feedstock pathways:
    <bullet> Ethanol from corn.
    <bullet> Ethanol from cellulosic materials (hybrid populars, 
switchgrass, and corn stover).
    <bullet> Biodiesel from soybean oil.
    <bullet> Methanol from renewable sources.
    <bullet> Natural gas from renewable sources.
    <bullet> Renewable diesel formulations.
    The contract focuses on the potential fuel production developments 
and efficiency improvements that could occur within the time-frame of 
the RFS program. The GREET input value changes resulting from this work 
are projected to be available in the fall of 2006, not in time for this 
proposal, but they will be incorporated into revised lifecycle 
assessments for the final rule.
    We did not investigate the input values associated with the 
production of petroleum-based gasoline or diesel fuel in the GREET 
model for this proposal. However, the refinery modeling discussed in 
Section VII will provide some additional information on the process 
energy requirements associated with the production of gasoline and 
diesel under a renewable fuels mandate. We will use information from 
this refinery modeling for the final rule to determine if any GREET 
input values should be changed.
    A summary of the GREET corn ethanol input values we investigated 
and modified for this proposal is given below. We also examined several 
other GREET input values, but determined that the default GREET values 
should not be changed for a variety of reasons. These included ethanol 
plant process efficiency, corn and ethanol transport distances and 
modes, corn farming inputs, CO<INF>2</INF> emissions from corn farming 
land use change, and byproduct allocation methods. Our investigation of 
these other GREET input values are discussed more fully in Chapter 6 of 
the RIA. The current GREET default factors for these other inputs were 
included in the analysis for this proposal.
    a. Wet-Mill Versus Dry Mill Ethanol Plants. The two basic methods 
for producing ethanol from corn are wet milling and dry milling. In the 
wet milling process, the corn is soaked to separate the starch, used to 
make ethanol, from the other components of the corn kernel. In the dry 
milling process, the entire corn kernel is ground and fermented to 
produce ethanol. The remaining components of the corn are then dried 
for animal feed (dried distillers grains with solubles, or DDGS). Wet 
milling is more complicated and expensive than dry milling, but it 
produces more valuable products (ethanol plus corn syrup, corn oil, and 
corn gluten meal and feeds). The majority of ethanol plants in the 
United States are dry mill plants, which produce ethanol more simply 
and efficiently. The GREET default is 70 percent dry mill, 30 percent 
wet mill.
    For this analysis, we expect most new ethanol plants will be dry 
mill operations. That has been the trend in the last few years as the 
demand for ethanol has grown, and our analysis of ethanol plants under 
construction and planned for the near future has verified this. 
Therefore, it was assumed that essentially all new ethanol facilities 
would be dry mill plants.
    b. Coal Versus Natural Gas in Ethanol Plants. The type of fuel used 
within the ethanol plant for process energy, to power the various 
components that are used in ethanol production (dryers, grinders, 
heating, etc.) can vary among ethanol plants. The type of fuel used has 
an impact on the energy usage, efficiency, and emissions of the plant, 
and is primarily determined by economics. Most new plants built in the 
last few years have used natural gas. Based on specific situations and 
economics, some new plants are using coal. In addition, EPA is 
promoting the use of combined heat and power, or cogeneration, in 
ethanol plants to improve plant energy-efficiency and to reduce air 
emissions. This technology, in the face of increasing natural gas 
prices, may make coal a more attractive energy source for new ethanol 
plants.
    GREET assumes that 20 percent of plants will be powered by coal. 
However, our review of plants under construction and those planned for 
the near future indicates that coal will only be used for approximately 
10% of the plants. This is the value we assumed in GREET for our 
analysis. However, as new plants are constructed to meet the demands of 
the RFS, this percentage is expected to go up. Future work in 
preparation for the final rule will evaluate the potential trends for 
combined heat and power and coal as process fuel.
    c. Ethanol Production Yield. It is generally assumed that 1 bushel 
of corn yields 2.7 gallons of ethanol. However, the development of new 
enzymes continues to increase the potential ethanol yield. We used a 
value of 2.71 gal/bu in our analysis. This value represents pure 
ethanol production (i.e. no denaturant). This value is consistent with 
the cost modeling of corn ethanol discussed in Section VII.
2. Controversy Concerning the Ethanol Energy Balance
    Although we have made use of lifecycle impact estimates from ANL's 
GREET model, there are a variety of lifecycle impact analyses from 
other researchers that provide alternative and sometimes significantly 
different estimates. The lifecycle energy balance for corn-ethanol, in 
particular, has been the subject of numerous and sometimes contentious 
debates.
    Several metrics are commonly used to describe the energy efficiency 
of renewable fuels. We have chosen to use displacement indexes for this 
proposal because they provide the least ambiguous and most relevant 
mechanism for estimating the impacts of renewable fuels on GHGs and 
petroleum consumption. However, other metrics, such as the net energy 
balance and energy efficiency, have more commonly been used in the 
past. The use of these metrics has served to complicate the issue since 
they do not involve a direct comparison to the gasoline that the 
ethanol is replacing.
    Among researchers who have studied the lifecycle energy balance of 
corn-ethanol, the primary differences of opinion appear to center on 
fossil energy associated with fertilizers, the

[[Page 55627]]

energy required to convert corn into ethanol, and the value of co-
products. As a result of these differences, the net energy balance has 
been estimated to be somewhere between -34 and + 31 thousand Btu/gal, 
and the energy efficiency has been estimated to be somewhere between 
0.6 and 1.4.\89\ A concern arises in cases where a researcher concludes 
that the net energy balance is negative, or the energy efficiency is 
less than 1.0. Such cases would indicate that the fossil energy used in 
the production and transportation of ethanol exceeds the energy in the 
ethanol itself, and this is generally interpreted to mean that 
lifecycle fossil fuel use negates the benefits of replacing gasoline 
with ethanol. However, since the metrics used do not actually compare 
ethanol to gasoline, such interpretations are unwarranted.

    \89\ A net energy balance of zero, or an energy efficiency of 
1.0, would indicate that the full lifecycle fossil fuels used in the 
production and transportation of ethanol are exactly equal to the 
energy in the ethanol itself.
---------------------------------------------------------------------------

    The primary studies that conclude that the energy balance is 
negative were conducted by Dr. David Pimental of Cornell University and 
Dr. T. Patzek of University of California, Berkeley <SUP>90 91</SUP>. 
Many other researchers, however, have criticized that work as being 
based on out-dated farming and ethanol production data, including data 
not normally considered in lifecycle analysis for fuels, and not 
following the standard methodology for lifecycle analysis in terms of 
valuing co-products. Furthermore, several recent surveys have concluded 
that the energy balance is positive, although they differ in their 
numerical estimates.<SUP>92 93 94</SUP> Authors of the GREET model have 
also concluded that the lifecycle amount of fossil energy used to 
produce ethanol is less than the amount of energy in the ethanol 
itself. Based on our review of all the available information, we have 
concluded that the energy balance is indeed positive, and we believe 
that the GREET model provides an accurate basis for quantifying the 
lifecycle impacts.

B. Overview of Methodology

    The GREET model does not provide estimates of energy consumed and 
emissions generated in total, such as the total amount of natural gas 
consumed in the U.S. in a given year by ethanol production facilities. 
Instead, it provides estimates on a national average, per fuel unit 
basis, such as the amount of natural gas consumed for the average 
ethanol production facility per million Btus of ethanol produced. As a 
result we could not use GREET directly to estimate the nationwide 
impacts of replacing some gasoline and diesel with renewable fuels.
    Instead, we used GREET to generate comparisons between renewable 
fuels and the petroleum-based fuels that they displace. These 
comparisons allowed us to develop displacement indexes that represent 
the amount of lifecycle GHGs or fossil fuel reduced when a Btu of 
renewable fuel replaces a Btu of gasoline or diesel. In order to 
estimate the incremental impacts of increased use of renewable fuels on 
GHGs and fossil fuels, we combined those displacement indexes with our 
renewable fuel volume scenarios and GHG emissions and fossil fuel 
consumption data for the conventional fuels replaced. For example, to 
estimate the impact of corn-ethanol use on GHGs, these factors were 
combined in the following way:

S<INF>GHG,corn ethanol</INF> = R<INF>corn ethanol</INF> x 
LC<INF>gasoline</INF> x DI<INF>GHG,corn ethanol</INF>

Where:

S<INF>GHG,corn ethanol</INF> = Lifecycle GHG emission reduction 
relative to the 2012 reference case associated with use of corn 
ethanol (million tons of GHG).
R<INF>corn ethanol</INF> = Amount of gasoline replaced by corn 
ethanol on an energy basis (Btu).
LC<INF>gasoline</INF> = Lifecycle emissions associated with gasoline 
use (million tons of GHG per Btu of gasoline).
DI<INF>GHG,corn ethanol</INF> = Displacement Index for GHGs and corn 
ethanol, representing the percent reduction in gasoline lifecycle 
GHG emissions which occurs when a Btu of gasoline is replaced by a 
Btu of corn ethanol.

    Variations of the above equation were also generated for impacts on 
all four endpoints of interest (emissions of CO2, emissions of GHGs, 
fossil fuel consumption, and petroleum consumption) as well as all 
three renewable fuels examined (corn-ethanol, cellulosic ethanol, and 
biodiesel). Each of the variables in the above equation are discussed 
in more detail below. Section 6 of the DRIA provides details of the 
analysis.
1. Amount of Conventional Fuel Replaced by Renewable Fuel (R)
    In general, the volume fraction (R) represents the amount of 
conventional fuel no longer consumed--that is, displaced--as a result 
of the use of the replacement renewable fuel. Thus R represents the 
total amount of renewable fuel used under each of our renewable fuel 
volume scenarios, in units of Btu. We make the assumption that vehicle 
energy efficiency will not be affected by the presence of renewable 
fuels (i.e., efficiency of combusting one Btu of ethanol is equal to 
the efficiency of combusting one Btu of gasoline).
    Consistent with the emissions modeling described in Section VII, 
our analysis of the GHG and fossil fuel consumption impacts of 
renewable fuel use was conducted using three volume scenarios. The 
first scenario was a base case representing 2004 renewable fuel 
production levels, projected to 2012. This scenario provided the point 
of comparison for the other two scenarios. The other two renewable fuel 
scenarios for 2012 represented the RFS program requirements and the 
volume projected by EIA. In both scenarios, we assumed that the 
biodiesel production volume would be 0.3 billion gallons based on an 
EIA projection, and that the cellulosic ethanol production volume would 
be 0.25 billion gallons based on the Energy Act's requirement that 250 
million gallons of cellulosic ethanol be produced starting in the next 
year, 2013. The remaining renewable fuel volumes in each scenario would 
be ethanol made from corn. The total volumes for all three scenarios 
are shown in Table IX.B.1-1. For the purposes of calculating the R 
values, we assumed the ethanol volumes are 5% denatured, and the 
volumes were converted to total Btu using the appropriate volumetric 
energy content values (76,000 Btu/gal for ethanol, and 118,000 Btu/gal 
for biodiesel).

------------------------------------------------------------------------

    Since the impacts of increased renewable fuel use were measured 
relative to the 2012 reference case, the value of R actually 
represented the incremental amount of renewable fuel between the 
reference case and each of the two other scenarios.
2. Lifecycle Impacts of Conventional Fuel Use (LC)
    In order to determine the lifecycle impact that increased renewable 
fuel volumes may have on any particular endpoint (fossil fuel 
consumption or emissions of GHGs), we also needed to know the 
conventional fuel inventory on a lifecycle basis. Since available 
sources of GHG emissions are provided on a direct rather than a 
lifecycle basis, we converted these direct emission and energy 
estimates into their lifecycle counterparts. We used GREET to develop 
multiplicative factors for converting direct (vehicle-based) emissions 
of GHGs and energy use into full lifecycle factors. Table IX.B.2-1 
shows the total lifecycle petroleum and GHG emissions associated with 
direct use of a Btu value of gasoline and diesel fuel.

       Table IX.B.2-1.--Lifecycle Emissions and Energy (LC Values)

CO2 (Tg-CO2/QBtu).............................         94.2         91.9
------------------------------------------------------------------------

3. Displacement Indexes (DI)
    The displacement index (DI) represents the percent reduction in GHG 
emissions or fossil fuel energy brought about by the use of a renewable 
fuel in comparison to the conventional gasoline or diesel that the 
renewable fuel replaces. The formula for calculating the displacement 
index depends on which fuel is being displaced (i.e. gasoline or 
diesel), and which endpoint is of interest (e.g. petroleum energy, 
GHG). For instance, when investigating the CO<INF>2</INF> impacts of 
ethanol used in gasoline, the displacement index is calculated as 
follows:
[GRAPHIC] [TIFF OMITTED] TP22SE06.005

    The units of g/Btu ensure that the comparison between the renewable 
fuel and the conventional fuel is made on a common basis, and that 
differences in the volumetric energy content of the fuels is taken into 
account. The denominator includes the CO<INF>2</INF> emitted through 
combustion of the gasoline itself in addition to all the CO<INF>2</INF> 
emitted during its manufacturer and distribution. The numerator, in 
contrast, includes only the CO<INF>2</INF> emitted during the 
manufacturer and distribution of ethanol, not the CO<INF>2</INF> 
emitted during combustion of the ethanol.
    The combustion of biomass-based fuels, such as ethanol from corn 
and woody crops, generates CO<INF>2</INF>. However, in the long run the 
CO<INF>2</INF> emitted from biomass-based fuels combustion does not 
increase atmospheric CO<INF>2</INF> concentrations, assuming the 
biogenic carbon emitted is offset by the uptake of CO<INF>2</INF> 
resulting from the growth of new biomass. As a result, CO<INF>2</INF> 
emissions from biomass-based fuels combustion are not included in their 
lifecycle emissions results and are not used in the CO<INF>2</INF> 
displacement index calculations shown above.
    Using GREET, we calculated the lifecycle values for energy consumed 
and GHGs produced for corn-ethanol, cellulosic ethanol, and soybean-
based biodiesel. These values were in turn used to calculate the 
displacement indexes. The results are shown in Table IX.B.3-1. Details 
of these calculations can be found in Chapter 6 of the RIA. As noted 
previously, different models can result in different estimates. For 
example, whereas GREET estimates a net GHG reduction of about 26% for 
corn ethanol compared to gasoline, the previously cited works by 
Farrell et al. estimates around a 13% reduction.

----------------------------------------------------------------------------------------------------------------

    The displacement indexes in this table represent the impact of 
replacing a Btu of gasoline or diesel with a Btu of renewable fuel. 
Thus, for instance, for every Btu of gasoline which is replaced by corn 
ethanol, the total lifecycle GHG emissions that would have been 
produced from that Btu of gasoline would be reduced by 25.8 percent. 
For every Btu of diesel which is replaced by biodiesel, the total 
lifecycle petroleum energy that would have been consumed as a result of 
burning that Btu of diesel fuel would be reduced by 84.6 percent.
    Note that our DI estimates for cellulosic ethanol assume that the 
ethanol in question was in fact produced from a cellulosic feedstock, 
such as wood, corn stalks, or switchgrass. However, the definition of 
cellulosic biomass ethanol given in the Energy Act also includes 
ethanol made from non-cellulosic feedstocks if 90 percent of the 
process energy used to operate the facility is derived from a renewable 
source. In the context of our cost analysis, we have assumed this 
latter definition of cellulosic ethanol. Further discussion of this 
issue can be found in Chapter 1, Section 1.2.2 of the RIA.

C. Impacts of Increased Renewable Fuel Use

    We used the methodology described above to calculate impacts of 
increased use of renewable fuels on consumption of petroleum and fossil 
fuels and also on emissions of CO<INF>2</INF> and GHGs. This section 
describes our results.
1. Fossil Fuels and Petroleum
    We used the equation for S above to calculate the reduction 
associated with the increased use of renewable fuels on lifecycle 
fossil fuels and petroleum. These values are then compared to the total 
U.S. transportation sector emissions to get a percent reduction. The 
results are presented in Tables IX.C.1-1 and IX.C.1-2.

------------------------------------------------------------------------

2. Greenhouse Gases and Carbon Dioxide
    One issue that has come to the forefront in the assessment of the 
environmental impacts of transportation fuels relates to the effect 
that the use of such fuels could have on emissions of greenhouse gases 
(GHGs). The combustion of fossil fuels has been identified as a major 
contributor to the increase in concentrations of atmospheric carbon 
dioxide (CO<INF>2</INF>) since the beginning of the industrialized era, 
as well as the build-up of trace GHGs such as methane (CH<INF>4</INF>) 
and nitrous oxide (N<INF>2</INF>O). This lifecycle analysis evaluates 
the impacts of renewable fuel use on greenhouse gas emissions.
    The relative global warming contribution of emissions of various 
greenhouse gases is dependant on their radiative forcing, atmospheric 
lifetime, and other considerations. For example, on a mass basis, the 
radiative forcing of CH<INF>4</INF> is much higher than that of 
CO<INF>2</INF>, but its effective atmospheric residence time is much 
lower. The relative warming impacts of various greenhouse gases, taking 
into account factors such as atmospheric lifetime and direct warming 
effects, are reported on a CO<INF>2</INF>-equivalent basis as global 
warming potentials (GWPs). The GWPs used by GREET were developed by the 
UN Intergovernmental Panel on Climate Change (IPCC) as listed in their 
Third Assessment Report \95\, and are shown in Table IX.C.2-1.

    Greenhouse gases are measured in terms of CO<INF>2</INF>-equivalent 
emissions, which result from multiplying the GWP for each of the three 
pollutants shown in the above table by the mass of emission for each 
pollutant. The sum of

[[Page 55630]]

impacts for CH<INF>4</INF>, N<INF>2</INF>O, and CO<INF>2</INF>, yields 
the total effective GHG impact.
    We used the equation for S above to calculate the reduction 
associated with the increased use of renewable fuels on lifecycle 
emissions of CO<INF>2</INF>. These values are then compared to the 
total U.S. transportation sector emissions to get a percent reduction. 
The results are presented in Table IX.C.2-2.

----------------------------------------------------------------------------------------------------------------

    Carbon dioxide is a subset of GHGs, along with CH<INF>4</INF> and 
N<INF>2</INF>O as discussed above. It can be seen from Table IX.B.3-1 
that the displacement index of CO<INF>2</INF> is greater than for GHGs 
for each renewable fuel. This indicates that lifecycle emissions of 
CH<INF>4</INF> and N<INF>2</INF>O are higher for renewable fuels than 
for the conventional fuels replaced. Therefore, reductions associated 
with the increased use of renewable fuels on lifecycle emissions of 
GHGs are lower than the values for CO<INF>2</INF>. The results for GHGs 
are presented in Table IX.C.2-3.

D. Implications of Reduced Imports of Petroleum Products

    This section only considers the impacts on imports of oil and 
petroleum products. Expanded production and use of renewable fuels 
could have other economic impacts such as on the exports of 
agricultural products like corn. See section X of the preamble for a 
discussion on agricultural sector impacts.
    In 2005, the United States imported almost 60 percent of the oil it 
consumed. This compares to just over 35 percent oil imports in 
1975.\96\ Transportation accounts for 70% of the U.S. oil consumption. 
It is clear that oil imports have a significant impact on the U.S. 
economy. Expanded production of renewable fuel is expected to 
contribute to energy diversification and the development of domestic 
sources of energy. We consider whether the RFS will reduce U.S. 
dependence on imported oil by calculating avoided expenditures on 
petroleum imports. Note that we do not calculate whether this reduction 
is socially beneficially, which would depend on the scarcity value of 
domestically produced ethanol versus that of imported petroleum 
products.

Data Book: 25th Edition, Oak Ridge National Laboratory, U.S. 
Department of Energy, ORNL-6974, 2006.
---------------------------------------------------------------------------

    To assess the impact of the RFS program on petroleum imports, the 
fraction of domestic consumption derived from foreign sources was 
estimated using results from the AEO 2006. In section 6.4.1 of the DRIA 
we describe how fuel producers change their mix in response to a 
decrease in fuel demand. We do not expect the projected reductions in 
petroleum consumption (0.3 to 0.57 Quads) to impact world oil prices by 
a measurable amount. We base this assumption on the overall size of 
worldwide petroleum demand and analysis of the AEO 2006 cases. As a 
consequence, domestic crude oil production for the 7.5 or 9.9 cases 
would not be expected to change significantly versus the RFS reference 
case. Thus, petroleum reductions will come largely from reductions in 
net petroleum imports. This conclusion is confirmed by comparing the 
AEO 2006 low macroeconomic growth case to the AEO 2006 reference case, 
as discussed in the RIA 6.4.1. The AEO 2006 shows that for a reduction 
in petroleum demand on the order of the reductions estimated for the 
RFS, net imports will account for approximately 95% of the reductions. 
However, if petroleum reductions were large enough to impact world oil 
prices, the mix of domestic crude oil, imports of finished products, 
and imports of crude oil used by fuel producers would change. We 
discuss this uncertainty in more detail in section 6.4.1 of the RIA and 
solicit comments to the extent by which the RFS may have a price effect 
and impact the imports of crude oil and refined products.
    We quantified the fraction of net petroleum imports that would be 
crude oil versus finished products. Comparison of same cases in the AEO 
2006 shows that finished products initially compose all the net import 
reductions, followed by imported crude oil once reductions in 
consumption reach beyond 1.2 Quads of petroleum product. However, there 
is significant uncertainty in quantifying how refineries will change 
their mix of sources with a decrease in petroleum demand, particularly 
at the levels estimated for the RFS. For example, a comparison between 
the AEO low price case (as opposed to low macroeconomic growth case) 
and the reference case would yield a 50-50 split between product and 
crude imports. We believe that the actual refinery response could range 
between these two points, so that finished product imports would 
compose between 50 to 100% of the net import reductions, with crude oil 
imports making up the remainder. For the purposes of this rulemaking, 
we show values for the case where net import reductions come entirely 
from imports of finished products, as shown below in Table IX.D-1. We 
compare these reductions in imports against the AEO projected levels of 
net petroleum imports. The range of reductions in net petroleum imports 
are estimated to be between 1 to 2%, as shown in Table IX.D-2.

    One of the effects of increased use of renewable fuel is that it 
diversifies the energy sources used in making transportation fuel. To 
the extent that diverse sources of fuel energy reduce the dependence on 
any one source, the risks, both financial as well as strategic, of 
potential disruption in supply or spike in cost of a particular energy 
source is reduced.
    To understand the energy security implications of the RFS, EPA will 
work with Oak Ridge National Laboratory (ORNL). As a first step, ORNL 
will update and apply the approach used in the 1997 report Oil Imports: 
An Assessment of Benefits and Costs, by Leiby, Jones, Curlee and 
Lee.\97\ This paper was cited and its results utilized in previous DOT/
NHTSA rulemakings, including the 2006 Final Regulatory Impact Analysis 
of CAFE Reform for Light Trucks.\98\ This approach is consistent with 
that used in the Effectiveness and Impact of Corporate Average Fuel 
Economy (CAFE) Standards Report conducted by the National Research 
Council/National Academy of Sciences in 2002. Both reports estimate the 
marginal benefits to society, in dollars per barrel, of reducing either 
imports or consumption. This ``oil premium'' approach emphasizes 
identifying those energy-security related costs that are not reflected 
in the market price of oil, and which may change in response to an 
incremental change in the level of oil imports or consumption.\99\

Russell Lee,Oil Imports: An Assessment of Benefits and Costs, ORNL-

    \99\ For instance, the 1997 ORNL study gave a range for the 
``oilpremium'' $0 to $13 per barrel (adjusted to $2004) based on 
1994 market conditions. The actual value depended on assumptions 
about the market power of foreign exporters and the monopsony power 
of the U.S., the risk of future oil price shocks and the employment 
of hedging strategies, and the connections between oil shocks and 
GNP.
---------------------------------------------------------------------------

    Since the 1997 publication of this report changes in oil market 
conditions, both current and projected, suggest that the magnitude of 
the ``oil premium'' may have changed. Significant factors that should 
be reconsidered include: Oil prices, current and anticipated levels of 
OPEC production, U.S. import levels, potential OPEC behavior and 
responses, and disruption likelihoods. ORNL will apply the most 
recently available careful quantitative assessment of disruption 
likelihoods, from the Stanford Energy Modeling Forum's 2005 workshop 
series, as well as other assessments \100\. ORNL will also revisit the 
issue of the macroeconomic consequences of oil market disruptions and 
sustained higher oil prices. Using the ``oil premium'' calculation 
methodology which combines short-run and long-run costs and benefits, 
and accounting for uncertainty in the key driving factors, ORNL will 
provide an updated range of estimates of the marginal energy security 
implications of displacing oil consumption with renewable fuels. The 
results of this work effort are not available for this proposal but 
will be part of the assessment of impacts of the RFS in the final rule. 
Although not directly applicable, financial economics literature has 
examined risk diversification. The agency is interested in ways to 
examine changes in risks associated with diversifying energy sources in 
general and solicits comments as such.

    We also calculate the decreased expenditures on petroleum imports 
and compare this with the U.S. trade position measured as U.S. net 
exports of all goods and services economy-wide. All reductions in 
petroleum imports are expected to be from finished petroleum products 
rather than crude oil. The reduced expenditures in petroleum product 
imports were calculated by multiplying the reductions in gasoline and 
diesel imports by their corresponding price. According to the EIA, the 
price of imported finished products is the market price minus domestic 
local transportation from refineries and minus taxes.\101\ An estimate 
was made by using the AEO 2006 gasoline and distillate price forecasts 
and subtracting the average Federal and state taxes based on historical 
data.\102\

Trends'', Office of Oil and Gas, DOE/EIA-0615, p. 71. (http://tonto.eia.doe.gov/FTPROOT/petroleum/061596.pdf)
    \102\ The average taxes per gallon of gasoline and diesel have 
stayedrelatively constant. For 2000-2006, gasoline taxes were $0.44/
gallon ($2004) while for 2002-2006, diesel taxes were $0.49/gallon. 
The average was taken from available EIA data (http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp).
---------------------------------------------------------------------------

    We compare these avoided petroleum import expenditures against the 
projected value of total U.S. net exports of all goods and services 
economy-wide. Net exports is a measure of the difference between the 
value of exports of goods and services by the U.S. and the value of 
U.S. imports of goods and services from the rest of the world. For 
example, according to the AEO 2006, the value of total import 
expenditures of goods and services exceeds the value of U.S. exports of 
goods and services to the rest of the world by $695 billion for 2006 
(for a net export level of minus $695 billion).\103\ This net exports 
level is projected to diminish to minus $383 billion by 2012. In Table 
IX.D-3, we compare the avoided expenditures in petroleum imports versus 
the total value of U.S. net exports of goods and services for the whole 
economy for 2012. Relative to the 2012 projection, the avoided 
petroleum expenditures due to the RFS would represent 0.9 to 1.5% of 
economy-wide net exports.
---------------------------------------------------------------------------

    \103\ For reference, the U.S. Bureau of Economic Analysis (BEA) 
reports that the 2005 import expenditures. on energy-related 
petroleum products totaled $235.5 billion (2004$) while petroleum 
exports totaled $13.6 billion--for a net of $221.9 billion in 
expenditures. Net petroleum expenditures made up a significant 
fraction of the $591.3 billion current account deficit in goods and 
services for 2005 (2004$). (http://www.bea.gov/)

X. Agricultural Sector Economic Impacts

    As described in more detail in the Draft Regulatory Impact Analysis 
accompanying this proposal, we plan to evaluate the economic impact on 
the agricultural sector. However, due to the timing of that analysis, 
it will not be completed until the final rule. In the meantime, we 
briefly describe here (and in more detail in the draft RIA) our planned 
analyses and the sources of assumptions which could critically impact 
those assessments. Finally, we ask for specific comment on the best 
sources of information we use in these analyses.
    We will be using the Forest and Agricultural Sector Optimization 
Model (``FASOM'') developed over the past 30 years by Bruce McCarl, 
Texas A&M University and others. This is a constrained optimization 
model which seeks to allocate resources and production to maximize 
producer plus consumer surpluses. We have consulted with a range of 
experts both within EPA as well as at our sister agencies, the U.S. 
Departments of Agriculture and Energy and they support the use of this 
model for assessing the economic impacts on the agricultural sector of 
various renewable fuel pathways evaluated in this rule. The objective 
of this modeling assessment is to predict the economic impacts that 
will directly result from the expanded use of farm products for 
transportation fuel production. We anticipate that the growing demand 
for corn for ethanol production in particular but also soybeans and 
other agricultural crops such as rapeseed and other oil seeds for 
biodiesel production will increase the production of these feedstocks 
and impact farm income. The additional corn to produce ethanol may come 
from several sources, including (1) more intensive cultivation of 
existing land that currently produces corn, (2) switching production 
from soybean and cotton to corn, (3) additional acres of land being 
cultivated, or (4) diversion from corn exports. The implications to 
U.S. net exports and environment effects partially depend on which 
source supplies more corn. Eventually various cellulose sources such as 
corn stover and switchgrass for cellulose-based ethanol production may 
well become highly demanded and also significantly impact the 
agricultural sector.
    Using the FASOM model, we will estimate the direct impact on farm 
income resulting from higher demand for corn and soybeans, for example. 
Additionally, we will estimate impacts on farm employment. Since we 
expect the higher demand for feedstock will increase both the supply 
and cost of feedstock, we will also consider how the higher renewable 
fuel feedstock cost impacts the cost of other agricultural products 
(corn and soy meal are important sources not only for directly making 
food for human consumption but also as feed for farm animals). As an 
estimate of the impact on corn and soybeans prices, we are relying on 
the estimates provided by the U.S. Department of Agriculture \104\ 
rather than using the FASOM model to derive these price impacts. 
Additionally, we will rely on the Energy Information Agency's estimates 
for fuel mix in predicting the amount of ethanol and biodiesel in the 
fuel pool. Other than these external constraints, we expect to use 
FASOM as the basic model for estimating economic impacts on farm sector 
and how these might more generally impact the U.S. economy. Note that 
this FASOM analysis is a partial equilibrium analysis, focusing almost 
exclusively on impacts in the U.S. agricultural sector. As a result, it 
cannot be utilized to make broader assessments of net social benefits 
resulting from this rulemaking, which for example would require 
evaluation of the transfer payments to farmers and ethanol producers 
from consumers and refiners.

XI. Public Participation

    We request comments on all aspects of this proposal. The comment 
period for this proposed rule will be November 12, 2006. Comments can 
be submitted to the Agency through any of the means listed under 
ADDRESSES above.
    We will hold a public hearing on October 13, 2006. The public 
hearing will start at 10 a.m. (Central) at the Sheraton Gateway Suites 
Chicago O'Hare, 6501 North Mannheim Road, Rosemont, Illinois 60018. If 
you would like to present testimony at the public hearing, we ask that 
you notify the contact person listed under FOR FURTHER INFORMATION 
CONTACT above at least ten days beforehand. You should estimate the 
time you will need for your presentation and identify any needed audio/
visual equipment. We suggest that you bring copies of your statement or 
other material for the EPA panel and the audience. It would also be 
helpful if you send us a copy of your statement or other materials 
before the hearing.
    We will arrange for a written transcript of the hearing and keep 
the official record of the hearing open for 30 days to allow for the 
public to supplement the record. You may make arrangements for copies 
of the transcript directly with the court reporter.

XII. Administrative Requirements

A. Executive Order 12866: Regulatory Planning and Review

    Under Executive Order (EO) 12866, (58 FR 51735, October 4, 1993) 
this action is a ``significant regulatory action'' because of the 
policy implications of the proposed rule. Even though EPA has estimated 
that renewable fuel use through 2012 will be sufficient to meet the 
levels required in the standard, the proposed rule reflects the first 
renewable fuel mandate at the Federal level. Accordingly, EPA submitted 
this action to the Office of Management and Budget (OMB) for review 
under EO 12866 and any changes made in response to OMB recommendations 
have been documented in the docket for this action.

B. Paperwork Reduction Act

    The information collection requirements in this proposed rule have 
been submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction

[[Page 55633]]

Act, 44 U.S.C. 3501 et seq. The Information Collection Request (ICR) 
document prepared by EPA has been assigned EPA ICR number 2242.01.
    The information is planned to be collected to ensure that the 
required amount of renewable fuel is used each year. The credit trading 
program required by the Energy Act will be satisfied through a program 
utilizing Renewable Identification Numbers (RIN), which serve as a 
surrogate for renewable fuel consumption. Our proposed RIN-based 
program would fulfill all the functions of a credit trading program, 
and thus would meet the Energy Act's requirements. For each calendar 
year, each obligated party would be required to submit a report to the 
Agency documenting the RINs it acquired, and showing that the sum of 
all RINs acquired were equal to or greater than its renewable volume 
obligation. The Agency could then verify that the RINs used for 
compliance purposes were valid by simply comparing RINs reported by 
producers to RINs claimed by obligated parties. The Agency will then 
calculate the total amount of renewable fuel produced each year.
    For fuel standards, Section 208(a) of the Clean Air Act requires 
that manufacturers provide information the Administrator may reasonably 
require to determine compliance with the regulations; submission of the 
information is therefore mandatory. We will consider confidential all 
information meeting the requirements of Section 208(c) of the Clean Air 
Act.
    The annual public reporting and recordkeeping burden for this 
collection of information is estimated to be 3.1 hours per response. 
Burden means the total time, effort, or financial resources expended by 
persons to generate, maintain, retain, or disclose or provide 
information to or for a Federal agency. This includes the time needed 
to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements 
which have subsequently changed; train personnel to be able to respond 
to a collection of information; search data sources; complete and 
review the collection of information; and transmit or otherwise 
disclose the information.
    A document entitled ``Information Collection Request (ICR); OMB-83 
Supporting Statement, Environmental Protection Agency, Office of Air 
and Radiation,'' has been placed in the public docket. The supporting 
statement provides a detailed explanation of the Agency's estimates by 
collection activity. The estimates contained in the docket are briefly 
summarized here:
    Estimated total number of potential respondents: 4,945.
    Estimated total number of responses: 4,970.
    Estimated total annual burden hours: 15,560.
    Estimated total annual costs: $2,911,000, including $1,806,240 in 
purchased services.
    An agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.
    To comment on the Agency's need for this information, the accuracy 
of the provided burden estimates, and any suggested methods for 
minimizing respondent burden, including the use of automated collection 
techniques, EPA has established a public docket for this rule, which 
includes this ICR, under Docket ID number EPA-OAR-2005-0161. Submit any 
comments related to the ICR for this proposed rule to EPA and OMB. See 
the ADDRESSES section at the beginning of this notice for where to 
submit comments to EPA. Send comments to OMB at the Office of 
Information and Regulatory Affairs, Office of Management and Budget, 
725 17th Street, NW., Washington, DC 20503, Attention: Desk Office for 
EPA. Since OMB is required to make a decision concerning the ICR 
between 30 and 60 days after publication in the Federal Register, a 
comment to OMB is best assured of having its full effect if OMB 
receives it by October 30, 2006. The final rule will respond to any OMB 
or public comments on the information collection requirements contained 
in this proposal.

C. Regulatory Flexibility Act

1. Overview
    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements under the Administrative 
Procedure Act or any other statute unless the agency certifies that the 
rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of today's rule on small 
entities, small entity is defined as: (1) A small business as defined 
by the Small Business Administration's (SBA) regulations at 13 CFR 
121.201 (see table below); (2) a small governmental jurisdiction that 
is a government of a city, county, town, school district or special 
district with a population of less than 50,000; and (3) a small 
organization that is any not-for-profit enterprise which is 
independently owned and operated and is not dominant in its field. The 
following table provides an overview of the primary SBA small business 
categories potentially affected by this regulation:

----------------------------------------------------------------------------------------------------------------

2. Background--Small Refiners Versus Small Refineries
    Title XV (Ethanol and Motor Fuels) of the Energy Policy Act 
provides, at Section 1501(a)(2) [42 U.S.C. 7545(o)(9)(A)-(D)], special 
provisions for ``small refineries'', such as a temporary exemption from 
the standards until calendar year 2011. The Act defines the term 
``small refinery'' as ``* * * a refinery for which the average 
aggregate daily crude oil throughput for a calendar year * * * does not 
exceed 75,000 barrels.'' This term is different from a small refiner, 
which is what the Regulatory Flexibility Act is concerned with. A small 
refiner is a small business that meets the criteria set out in SBA's 
regulations at 13 CFR 121.201; whereas a small refinery, per the Energy 
Policy Act, is a refinery where the annual crude throughput is less 
than or equal to 75,000 barrels (i.e., a small-capacity refinery), and 
could be owned by a

[[Page 55634]]

larger refiner that exceeds SBA's small entity size standards.
    Previous EPA fuel regulations have afforded regulatory flexibility 
provisions to small refiners, as we believe that refineries owned by 
small businesses generally face unique economic challenges, compared to 
larger refiners. As small refiners generally lack the resources 
available to larger companies (including those larger companies that 
own small-capacity refineries) to raise capital for any necessary 
investments for meeting regulatory requirements, these flexibility 
provisions were provided to reduce the disproportionate burden on those 
refiners that qualified as small refiners.
3. Summary of Potentially Affected Small Entities
    The refiners that are potentially affected by this proposed rule 
are those that produce gasoline. For our recent proposed rule ``Control 
of Hazardous Air Pollutants From Mobile Sources'' (71 FR 15804, 
Wednesday, March 29, 2006), we performed an industry characterization 
of potentially affected gasoline refiners; we used that industry 
characterization to determine which refiners would also meet the SBA 
definition of a small refiner under this proposal. From the industry 
characterization, we determined that there were 20 gasoline refiners 
that met the definition of a small refiner. Of these 20 refiners, 17 
owned refineries that also met the Energy Policy Act's definition of a 
small refinery.
4. Impact of the Regulations on Small Entities
    As previously stated, many aspects of the RFS program, such as the 
required amount of annual renewable fuel volumes, were specified in the 
Energy Policy Act. As shown above in Table III.D.3.c-2, the annual 
projections of ethanol production exceed the required annual renewable 
fuel volumes. When the small refinery exemption ends, it is anticipated 
that there will be over one billion gallons in excess RINs available. 
We believe that this large volume of excess RINs will also lower the 
costs of this program. If there were a shortage of RINs, or if any 
party were to `hoard' RINs, the cost of a RIN could be high; however 
with excess RINs, we believe that this program will not impose a 
significant economic burden on small refineries, small refiners, or any 
other obligated party. Further, we have determined that this proposed 
rule will not have a significant economic impact on a substantial 
number of small entities.
    When the Agency certifies that a rule will not have a significant 
economic impact on a substantial number of small entities, EPA's policy 
is to make an assessment of the rule's impact on any small entities and 
to engage the potentially regulated entities in a dialog regarding the 
rule, and minimize the impact to the extent feasible. The following 
sections discuss our outreach with the potentially affected small 
entities and proposed regulatory flexibilities to decrease the burden 
on these entities in compliance with the requirements of the RFS 
program
5. Small Refiner Outreach
    Although we do not believe that the RFS program would have a 
significant economic impact on a substantial number of small entities, 
EPA nonetheless has tried to reduce the impact of this rule on small 
entities. We held meetings with small refiners to discuss the 
requirements of the RFS program and the special provisions offered by 
the Energy Policy Act for small refineries.
    The Energy Policy Act set out the following provisions for small 
refineries:
    <bullet> A temporary exemption from the Renewable Fuels Standard 
requirement until 2011;
    <bullet> An extension of the temporary exemption period for at 
least two years for any small refinery where it is determined that the 
refinery would be subject to a disproportionate economic hardship if 
required to comply;
    <bullet> Any small refinery may petition, at any time, for an 
exemption based on disproportionate economic hardship; and,
    <bullet> A small refinery may waive its temporary exemption to 
participate in the credit generation program, or it may also ``opt-
in'', by waiving its temporary exemption, to be subject to the RFS 
requirement.
    During these meetings with the small refiners we also discussed the 
impacts of these provisions being offered to small refineries only. As 
stated above, three refiners met the definition of a small refiner, but 
their refineries did not meet the Act's definition of a small refinery; 
which naturally concerned the small refiners. Another concern that the 
small refiners had was that if this rule were to have a significant 
economic impact on a substantial number of small entities a lengthy 
SBREFA process would ensue (which would delay the promulgation of the 
RFS rulemaking, and thus provide less lead time for these small 
entities prior to the RFS program start date).
    Following our discussions with the small refiners, they provided 
three suggested regulatory flexibility options that they believed could 
further assist affected small entities in complying with the RFS 
program standard: (1) That all small refiners be afforded the Act's 
small refinery temporary exemption, (2) that small refiners be allowed 
to generate credits if they elect to comply with the RFS program 
standard prior to the 2011 small refinery compliance date, and (3) 
relieve small refiners who generate blending credits of the RFS program 
compliance requirements.
    We agreed with the small refiners'' suggestion that small refiners 
be afforded temporary exemption that the Act specifies for small 
refineries. Regarding the small refiners' second and third suggestions 
regarding credits, our proposed RIN-based program will automatically 
provide them with credit for any renewables that they blend into their 
motor fuels. Until 2011, small refiners will essentially be treated as 
oxygenate blenders and may separate RINs from batches and trade or sell 
these RINs.
6. Conclusions
    After considering the economic impacts of today's proposed rule on 
small entities, we certify that this action will not have a significant 
economic impact on a substantial number of small entities.
    While the Energy Policy Act provided for a temporary exemption for 
small refineries from the requirements of today's proposed rule, these 
parties will have to comply with the requirements following the 
exemption period. However, we still believe that small refiners 
generally lack the resources available to larger companies, and 
therefore find it necessary to extend the small refinery temporary 
exemption to all small refiners. Thus, we are proposing to allow the 
small refinery temporary exemption, as set out in the Act, to all 
qualified small refiners. In addition, past fuels rulemakings have 
included a provision that, to qualify for EPA's small refiner 
flexibilities, a refiner must have no more than 1,500 total corporate 
employees and have a crude capacity of no more than 155,000 bpcd 
(slightly higher than SBA's crude capacity limit of 125,000 bpcd). To 
be consistent with these previous rules, we are also proposing to allow 
those refiners that meet these criteria to be considered small refiners 
for this rulemaking. Lastly, we are proposing that small refiners may 
separate RINs from batches and trade or sell these RINs prior to 2011 
if the small refiner operates as a blender

[[Page 55635]]

    We continue to be interested in the potential impacts of this 
proposed rule on small entities and welcome comments on issues related 
to such impacts.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under Section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, Section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of Section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
Section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted.
    Before EPA establishes any regulatory requirements that may 
significantly or uniquely affect small governments, including tribal 
governments, it must have developed under Section 203 of the UMRA a 
small government agency plan. The plan must provide for notifying 
potentially affected small governments, enabling officials of affected 
small governments to have meaningful and timely input in the 
development of EPA regulatory proposals with significant Federal 
intergovernmental mandates, and informing, educating, and advising 
small governments on compliance with the regulatory requirements.
    EPA has determined that this rule does not contain a Federal 
mandate that may result in expenditures of $100 million or more for 
State, local, and tribal governments, in the aggregate, or the private 
sector in any one year. EPA has estimated that renewable fuel use 
through 2012 will be sufficient to meet the required levels. Therefore, 
individual refiners, blenders, and importers are already on track to 
meet rule obligations through normal market-driven incentives. Thus, 
today's rule is not subject to the requirements of Sections 202 and 205 
of the UMRA.
    This rule contains no Federal mandates for State, local, or tribal 
governments as defined by the provisions of Title II of the UMRA. The 
rule imposes no enforceable duties on any of these governmental 
entities. Nothing in the rule would significantly or uniquely affect 
small governments.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have Federalism implications.'' 
``Policies that have Federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    This proposed rule does not have Federalism implications. It will 
not have substantial direct effects on the States, on the relationship 
between the national government and the States, or on the distribution 
of power and responsibilities among the various levels of government, 
as specified in Executive Order 13132. Thus, Executive Order 13132 does 
not apply to this rule.
    In the spirit of Executive Order 13132, and consistent with EPA 
policy to promote communications between EPA and State and local 
governments, EPA specifically solicits comment on this proposed rule 
from State and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.''
    This proposed rule does not have tribal implications, as specified 
in Executive Order 13175. This rule would be implemented at the Federal 
level and collectively apply to refiners, blenders, and importers. EPA 
expects these entities to meet the standards on a collective basis 
through 2012 even without imposition of any RFS obligations on any 
individual party. Tribal governments will be affected only to the 
extent they purchase and use regulated fuels. Thus, Executive Order 
13175 does not apply to this rule. EPA specifically solicits additional 
comment on this proposed rule from tribal officials.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    Executive Order 13045: ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
to any rule that: (1) Is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under Section 5-501 of the Order has the 
potential to influence the regulation. This proposed rule is not 
subject to Executive Order 13045 because it does not establish an 
environmental standard intended to mitigate health or safety risks and 
because it implements specific standards established by Congress in 
statutes.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This rule is not a ``significant energy action'' as defined in 
Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355 
(May 22, 2001)) because it is not likely to have a significant adverse 
effect on the supply, distribution, or use of energy.
    EPA expects the provisions to have very little effect on the 
national fuel supply, since normal market forces alone are promoting 
greater renewable fuel use than required by the RFS mandate. 
Nevertheless, the rule is an important part of the nation's efforts to 
reduce dependence on foreign oil. We discuss our analysis of the energy 
and supply effects of the increased use of renewable fuels in Sections 
VI and X of this preamble.

I. National Technology Transfer Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. The NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    This proposed rulemaking does not involve technical standards. 
Therefore, EPA is not considering the use of any voluntary consensus 
standards.

XIII. Statutory Authority

    Statutory authority for the rules proposed today can be found in 
section 211 of the Clean Air Act, 42 U.S.C. 7545. Additional support 
for the procedural and compliance related aspects of today's proposal, 
including the proposed recordkeeping requirements, come from Sections 
114, 208, and 301(a) of the CAA, 42 U.S.C. 7414, 7542, and 7601(a).

List of Subjects in 40 CFR Part 80

Gasoline, Imports, Incorporation by reference, Labeling, Motor vehicle 
pollution, Penalties, Reporting and recordkeeping requirements.

    Dated: September 7, 2006.
Stephen L. Johnson,
Administrator.
    40 CFR part 80 is proposed to be amended as follows:

PART 80--REGULATION OF FUELS AND FUEL ADDITIVES

    1. The authority citation for part 80 continues to read as follows:

    Authority: 42 U.S.C. 7414, 7542, 7545, and 7601(a).

    2. Section 80.1100 is revised to read as follows:


Sec.  80.1100  How is the statutory default requirement for 2006 
implemented?

    (a) Definitions. The definitions of Sec.  80.2 and the following 
additional definitions apply to this section only.
    (1) Renewable fuel. (i) Renewable fuel means motor vehicle fuel 
that is used to replace or reduce the quantity of fossil fuel present 
in a fuel mixture used to operate a motor vehicle, and which:
    (A) Is produced from grain, starch, oil seeds, vegetable, animal, 
or fish materials including fats, greases, and oils, sugarcane, sugar 
beets, sugar components, tobacco, potatoes, or other biomass; or
    (B) Is natural gas produced from a biogas source, including a 
landfill, sewage waste treatment plant, feedlot, or other place where 
decaying organic material is found.
    (ii) The term ``renewable fuel'' includes cellulosic biomass 
ethanol, waste derived ethanol, biodiesel, and any blending components 
derived from renewable fuel.
    (2) Cellulosic biomass ethanol means ethanol derived from any 
lignocellulosic or hemicellulosic matter that is available on a 
renewable or recurring basis, including dedicated energy crops and 
trees, wood and wood residues, plants, grasses, agricultural residues, 
fibers, animal wastes and other waste materials, and municipal solid 
waste. The term also includes any ethanol produced in facilities where 
animal wastes or other waste materials are digested or otherwise used 
to displace 90 percent or more of the fossil fuel normally used in the 
production of ethanol.
    (3) Waste derived ethanol means ethanol derived from animal wastes, 
including poultry fats and poultry wastes, and other waste materials, 
or municipal solid waste.
    (4) Small refinery means a refinery for which the average aggregate 
daily crude oil throughput for a calendar year (as determined by 
dividing the aggregate throughput for the calendar year by the number 
of days in the calendar year) does not exceed 75,000 barrels.
    (5) Biodiesel means a diesel fuel substitute produced from 
nonpetroleum renewable resources that meets the registration 
requirements for fuels and fuel additives established by the 
Environmental Protection Agency under section 211 of the Clean Air Act. 
It includes biodiesel derived from animal wastes (including poultry 
fats and poultry wastes) and other waste materials, or biodiesel 
derived from municipal solid waste and sludges and oils derived from 
wastewater and the treatment of wastewater.
    (b) Renewable fuel standard for 2006. The percentage of renewable 
fuel in the total volume of gasoline sold or dispensed to consumers in 
2006 in the United States shall be a minimum of 2.78 percent on an 
annual average volume basis.
    (c) Responsible parties. Parties collectively responsible for 
attainment of the standard in paragraph (b) of this section are 
refiners (including blenders) and importers of gasoline. However, a 
party that is a refiner only because he owns or operates a small 
refinery is exempt from this responsibility.
    (d) EPA determination of attainment. EPA will determine after the 
close of 2006 whether or not the requirement in paragraph (b) of this 
section has been met. EPA will base this determination on information 
routinely published by the Energy Information Administration on the 
annual domestic volume of gasoline sold or dispensed to U.S. consumers 
and of ethanol produced for use in such gasoline, supplemented by 
readily available information concerning the use in motor fuel of other 
renewable fuels such as cellulosic biomass ethanol, waste derived 
ethanol, biodiesel, and other non-ethanol renewable fuels.
    (1) The renewable fuel volume will equal the sum of all renewable 
fuel volumes used in motor fuel, provided that:
    (i) One gallon of cellulosic biomass ethanol or waste derived 
ethanol shall be considered to be the equivalent of 2.5 gallons of 
renewable fuel; and
    (ii) Only the renewable fuel portion of blending components derived 
from renewable fuel shall be counted towards the renewable fuel volume.
    (2) If the nationwide average volume percent of renewable fuel in 
gasoline in 2006 is equal to or greater than the standard in paragraph 
(b) of this section, the standard has been met.
    (e) Consequence of nonattainment in 2006. In the event that EPA 
determines that the requirement in paragraph (b) of this section has 
not been attained in 2006, a deficit carryover volume shall be added to 
the renewable fuel volume obligation for 2007 for use in calculating 
the standard applicable to gasoline in 2007.
    (1) The deficit carryover volume shall be calculated as follows:


DC = Vgas* (Rs-Ra)

Where:

DC = Deficit carryover in gallons of renewable fuel.
Vgas = Volume of gasoline sold or dispensed to U.S. consumers in 
2006, in gallons.
Rs = 0.0278.
Ra = Ratio of renewable fuel volume divided by total gasoline volume 
determined in accordance with paragraph (d)(2) of this section.

    (2) There shall be no other consequence of failure to attain the 
standard in paragraph (b) of this section in 2006 for any of the 
parties in paragraph (c) of this section.

[[Page 55637]]

    3. Section 80.1101 is added to read as follows:

    (vii) Municipal solid waste.
    (2) Ethanol made at facilities at which animal wastes or other 
waste materials are digested or otherwise used onsite to displace 90 
percent or more of the fossil fuel that is combusted to produce thermal 
energy integral to the process of making ethanol and which comply with 
the recordkeeping requirements of Sec.  80.1151(a)(4).
    (b) Other waste materials means either of the following:
    (1) Waste materials that are residues rather than being produced 
solely for the purpose of being combusted to produce energy (e.g., 
residual tops, branches, and limbs from a tree farm could be waste 
materials while wood chips used as fuel and which come from plants 
grown solely for such purpose would not be waste materials).
    (2) Waste heat that is captured from an off-site combustion process 
(e.g., furnace, boiler, heater, or chemical process).
    (c) Otherwise used means either of the following:
    (1) The direct combustion of the waste materials to make thermal 
energy.
    (2) The use of waste heat as a source of thermal energy.
    (d) Waste derived ethanol means ethanol derived from either of the 
following:
    (1) Animal wastes, including poultry fats and poultry wastes, and

ethanol, waste derived ethanol, biodiesel (mono-alkyl ester), non-ester 
renewable diesel, and blending components derived from renewable fuel.
    (3) Small volume additives less than 1.0 percent of the total 
volume of a renewable fuel shall be counted as part of the total 
renewable fuel volume.
    (4) A fuel produced by a renewable fuel producer that is used in 
boilers or heaters is not a motor vehicle fuel, and therefore is not a 
renewable fuel.
    (g) Blending component has the same meaning as ``Gasoline blending 
stock, blendstock, or component'' as defined at Sec.  80.2(s), for 
which the portion that can be counted as renewable fuel is calculated 
as set forth in Sec.  80.1115(a).

additive which:
    (1) Is registered as a motor vehicle fuel or fuel additive under 40 
CFR part 79;
    (2) Is a mono-alkyl ester;
    (3) Meets ASTM D-6751-02a;
    (4) Is intended for use in engines that are designed to run on 
conventional diesel fuel, and

    (3) Is intended for use in engines that are designed to run on 
conventional diesel fuel; and
    (4) Is derived from nonpetroleum renewable resources (as defined in 
paragraph (o) of this section).
    (l) Biocrude means plant oils or animal fats that are used as 
feedstocks to any production unit in a refinery that normally processes 
crude oil to make gasoline or diesel fuels.
    (m) Biocrude-based renewable fuels are renewable fuels that are 
gasoline or diesel products resulting from the processing of biocrudes 
in atmospheric distillation or other process units at refineries that 
normally process petroleum-based feedstocks.
    (n) Importers, for the purposes of this subpart only, are those 
persons who:
    (1) Are considered importers under Sec.  80.2(r); and

Sec. Sec.  80.1102-80.1103  [Added and Reserved]

    4. Sections 80.1102 and 80.1103 are added and reserved.
    5. Sections 80.1104 through 80.1107 are added to read as follows:


Sec.  80.1104  What are the implementation dates for the Renewable Fuel 
Standard Program?

    The RFS standards and other requirements of this subpart are 
effective beginning the day after [DATE 60 DAYS AFTER PUBLICATION OF 
THE FINAL RULE IN THE FEDERAL REGISTER.


Sec.  80.1105  What is the Renewable Fuel Standard?

    (a) The annual value of the renewable fuel standard for 2007 shall 
be 3.71 percent.
    (b) Beginning with the 2008 compliance period, EPA will calculate 
the value of the annual standard and publish this value in the Federal 
Register by November 30 of the year preceding the compliance period.
    (c) EPA will base the calculation of the standard on information 
provided by the Energy Information Administration regarding projected 
gasoline volumes and projected volumes of renewable fuel expected to be 
used in gasoline blending for the upcoming year.
    (d) EPA will calculate the annual renewable fuel standard using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TP22SE06.006

Where:

RFStd<INF>i</INF> = Renewable Fuel Standard in year i, in percent.
RFV<INF>i</INF> = Nationwide annual volume of renewable fuels 
required by section 211(o)(2)(B) of the Act (42 U.S.C. 7545) for

that is required to come from cellulosic sources, in year i, in 
gallons (250,000,000 gallons minimum).

(e) Beginning with the 2013 compliance period, EPA will calculate the 
value of the annual cellulosic standard and publish this value in the 
Federal Register by November 30 of the year preceding the compliance 
period.
(f) EPA will calculate the annual cellulosic standard using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TP22SE06.007

Where:

Sec.  80.1106  To whom does the Renewable Volume Obligation apply?

    (a)(1) An obligated party is a refiner or blender which produces 
gasoline within the 48 contiguous states, or an importer which imports 
gasoline into the 48 contiguous states.
    (2) If the Administrator approves a petition of Alaska, Hawaii, or 
a United States territory to opt-in to the renewable fuel program under 
the provisions in Sec.  80.1143, then ``obligated party'' shall include 
any refiner or blender which produces gasoline within that state or 
territory, or an importer which imports gasoline into that state or 
territory.
    (b)(1) For each calendar year starting with 2007, any obligated 
party is required to demonstrate, pursuant to Sec.  80.1127, that they 
have satisfied the Renewable Volume Obligation for that calendar year, 
as specified in Sec.  80.1107(a), except as otherwise provided in this 
section.
    (2) The deficit carryover provisions in Sec.  80.1127(b) only apply 
if all of the requirements specified in Sec.  80.1127(b) are fully 
satisfied.
    (c) Any blender whose sole blending activity in a calendar year is 
to blend a renewable fuel (or fuels) into gasoline, RBOB, CBOB, or 
diesel fuel is not required to meet the renewable volume obligation 
specified in Sec.  80.1107(a) for that gasoline for that calendar year.


Sec.  80.1107  How is the Renewable Volume Obligation calculated?

    For the purposes of this section, all reformulated gasoline, 
conventional gasoline and blendstock, collectively called ``gasoline'' 
unless otherwise specified, is subject to the requirements under this 
subpart, as applicable.
    (a) The Renewable Volume Obligation for an obligated party is 
determined according to the following formula:
RVO<INF>i</INF> = RFStd<INF>i</INF> x GV<INF>i</INF> + 
D<INF>i</INF><INF>-</INF><INF>1</INF>
Where:

RVO<INF>i</INF> = The Renewable Volume Obligation for a refiner, 
blender, or importer for calendar year i, in gallons of renewable 
fuel.
RFStd<INF>i</INF> = The renewable fuel standard for calendar year i 
from Sec.  80.1105, in percent.
GV<INF>i</INF> = The non-renewable gasoline volume, determined in 
accordance with paragraphs (b), (c), and (d) of this section, which 
is produced or imported, in year i, in gallons.
D<INF>i-1</INF> = Renewable fuel deficit carryover from the previous 
year, per Sec.  80.1127(b), in gallons.

    (b) The non-renewable gasoline volume for a refiner, blender, or 
importer for a given year, GV<INF>i</INF>, specified in paragraph (a) 
of this section is calculated as follows:
[GRAPHIC] [TIFF OMITTED] TP22SE06.008

Where:

x = Batch.
n = Total number of batches of gasoline produced or imported.
G<INF>x</INF> = Total volume of gasoline produced or imported, per 
paragraph (c) of this section, in gallons.
    RB<INF>x</INF> = Total volume of renewable fuel blended into 
gasoline, in gallons.


[[Page 55639]]


    (c) For the purposes of this section, all of the following products 
that are produced or imported during a calendar year are to be included 
in the volume used to calculate a party's renewable volume obligation 
under paragraph (a) of this section, except as provided in paragraph 
(d) of this section:
    (1) Reformulated gasoline.
    (2) Conventional gasoline.
    (3) Reformulated gasoline blendstock for oxygenate blending 
(``RBOB'').
    (4) Conventional gasoline blendstock that becomes finished

Sec. Sec.  80.1108-80.1114  [Added and Reserved]

    6. Sections 80.1108 through 80.1114 are added and reserved.
    7. Section 80.1115 is added to read as follows:


Sec.  80.1115  How are equivalence values assigned by renewable fuel 
producers?

    (a) Each gallon of a renewable fuel shall be assigned an 
equivalence value. The equivalence value is a number assigned to every 
renewable fuel that is used to determine how many gallon-RINs can be 
generated for a batch of renewable fuel according to Sec.  80.1126. 
Equivalence Values for certain renewable fuels are assigned in 
paragraph (d) of this section. For other renewable fuels, the 
equivalence value shall be calculated using the following formula:


EV = (R / 0.931) * (EC / 77,550)
Where:

EV = Equivalence Value for the renewable fuel.
R = Renewable content of the renewable fuel. This is a measure of 
the portion of a renewable fuel that came from a renewable source, 
expressed as a percent, on an energy basis, of the renewable fuel 
that comes from a renewable feedstock.
EC = Energy content of the renewable fuel, in Btu per gallon (lower 
heating value).

    (b) Technical justification and approval of calculation of the 
Equivalence Value.
    (1) Producers of renewable fuels must prepare a technical 
justification of the calculation of the Equivalence Value for the 
renewable fuel including a description of the renewable fuel, its 
feedstock and production process.
    (2) Producers shall submit the justification to the EPA for 
approval.
    (3) The Agency will review the technical justification and assign 
an appropriate Equivalence Value to the renewable fuel based on the 
procedure in paragraph (c) of this section.
    (c) The equivalence value is assigned as follows:
    (1) A value rounded to the nearest tenth if such value is less than 
0.9.
    (2) 1.0 if the calculated equivalence value is in the range of 0.9 
to 1.2.
    (3) 1.3, 1.5, or 1.7, for calculated values over 1.2, whichever 
value is closest to the calculated equivalence value, based on the 
positive difference between the calculated equivalence value and each 
of these three values, except as specified in paragraphs (c)(4) and 
(c)(5) of this section.
    (4) 2.5 for cellulosic biomass ethanol that is produced on or 
before December 31, 2012.
    (5) 2.5 for waste derived ethanol.
    (d) Equivalence values for some renewable fuels are as given in the 
following table:

Sec. Sec.  80.1116--80.1124  [Added and Reserved]

    8. Sections 80.1116 through 80.1124 are added and reserved.
    9. Sections 80.1125 through 80.1131 are added to read as follows:


Sec.  80.1125  Renewable Identification Numbers (RINs).

    Each RIN is a 34 character numerical code of the following form:


YYYYCCCCFFFFFBBBBBRRDKSSSSSSEEEEEE

    (a) YYYY is the calendar year in which the batch of renewable fuel 
was produced or imported. YYYY also represents the year in which the 
RIN was originally generated.
    (b) CCCC is the registration number assigned according to Sec.  
80.1150 to the producer or importer of the batch of renewable fuel.
    (c) FFFFF is the registration number assigned according to Sec.  
80.1150 to the facility at which the batch of renewable fuel was 
produced or imported.
    (d) BBBBB is a serial number assigned to the batch which:
    (1) Is chosen by the producer or importer of the batch such that no 
two batches have the same value in a given calendar year;
    (2) Begins with the value 00001 for the first batch produced or 
imported by a facility in a given calendar year; and
    (3) Increases sequentially for subsequent batches produced or 
imported by that facility in that calendar year.
    (e) RR is a number representing the equivalence value of the 
renewable fuel.
    (1) Equivalence values are specified in Sec.  80.1115.
    (2) Multiply the equivalence value by 10 to produce the value for 
RR.
    (f) D is a number identifying the type of renewable fuel, as 
follows:
    (1) D has the value of 1 if the renewable fuel can be categorized 
as cellulosic biomass ethanol.

[[Page 55640]]

    (2) D has the value of 2 if the renewable fuel cannot be 
categorized as cellulosic biomass ethanol.
    (g) K is a number identifying the type of RIN as follows:
    (1) K has the value of 1 if the batch-RIN is a standard-value RIN.
    (2) K has the value of 2 if the batch-RIN is an extra-value RIN.
    (h) SSSSSS is a number representing the first gallon associated 
with a batch of renewable fuel.
    (i) EEEEEE is a number representing the last gallon associated with 
a batch of renewable fuel. EEEEEE will be identical to SSSSSS in the 
case of a gallon-RIN. Assign the value of EEEEEE as described in Sec.  
80.1126.


Sec.  80.1126  How are RINs assigned to batches of renewable fuel by 
renewable fuel producers or importers?

    (a) Regional applicability. (1) Except as provided in paragraph (b) 
of this section, every batch of renewable fuel produced by a facility 
located in the contiguous 48 states of the United States, or imported 
into the contiguous 48 states, must be assigned a RIN.
    (2) If the Administrator approves a petition of Alaska, Hawaii, or 
a United States territory to opt-in to the renewable fuel program under 
the provisions in Sec.  80.1143, then the requirements of paragraph 
(a)(1) of this section shall also apply to renewable fuel produced or 
imported into that state or territory beginning in the next calendar 
year.
    (b) Volume threshold. Pursuant to Sec.  80.1154, producers with 
renewable fuel production facilities located within the United States 
that produce less than 10,000 gallons of renewable fuel each year, and 
importers that import less than 10,000 gallons of renewable fuel each 
year, are not required to generate and assign RINs to batches of 
renewable fuel. Such producers and importers are also exempt from the 
registration, reporting, and recordkeeping requirements of Sec. Sec.  
80.1150 through 80.1152. However, for those producers and importers 
that voluntarily generate and assign RINs, all the requirements of this 
subpart apply.
    (c) Generation of RINs. (1) The producer or importer of a batch of 
renewable fuel must generate the RINs associated with that batch. 
However, a producer of a batch of renewable fuel for export is not 
required to generate a RIN for that batch if that producer is also the 
exporter and exports the renewable fuel.
    (2) A party generating a RIN shall specify the appropriate 
numerical values for each component of the RIN in accordance with the 
provisions of Sec.  80.1125 and this paragraph (c).
    (3) Standard-value RINs shall be generated separately from extra-
value RINs, and distinguished from one another by the K component of 
the RIN.
    (4) When a standard-value batch-RIN or an extra-value batch-RIN is 
initially generated by a renewable fuel producer or importer, the value 
of SSSSSS in the batch-RIN shall be 000001 to represent the first 
gallon in the batch of renewable fuel.
    (5) Generation of standard-value batch-RINs. (i) Except as provided 
in paragraph (c)(5)(ii) of this section, a standard-value batch-RIN 
shall be generated to represent the gallons in a batch of renewable 
fuel. The value of EEEEEE when a batch-RIN is initially generated by a 
renewable fuel producer or importer shall be determined as follows:
    (A) For renewable fuels with an equivalence value of 1.0 or 
greater, the value of EEEEEE shall be the standardized volume of the 
batch in gallons.
    (B) For renewable fuels with an equivalence value of less than 1.0, 
the value of EEEEEE shall be the applicable volume, in gallons, 
calculated according to the following formula:

V<INF>a</INF> = EV * V<INF>s</INF>

Where:

V<INF>a</INF> = Applicable volume of renewable fuel, in gallons, for 
use in designating the value of EEEEEE.
EV = Equivalence value for the renewable fuel per Sec.  80.1115.
V<INF>s</INF> = Standardized volume of the batch of renewable fuel 
at 60 [deg]F, in gallons.

    (ii) For biocrude-based renewable fuels, a standard-value batch-RIN 
shall be generated to represent the gallons of biocrude rather than the 
gallons of renewable fuel. The value of EEEEEE shall be the 
standardized volume of the biocrude in gallons.
    (6) Generation of extra-value batch-RINs. (i) Extra-value batch-
RINs may be generated for renewable fuels having an equivalence value 
greater than 1.0.
    (ii) The value for EEEEEE in an extra-value batch-RIN when a batch-
RIN is initially generated by a renewable fuel producer or importer 
shall be the applicable volume of renewable fuel calculated according 
to the following formula:

V<INF>a</INF> = (EV-1.0) * V<INF>s</INF>

Where:

V<INF>a</INF> = Applicable volume of renewable fuel, in gallons, for 
use in designating the value of EEEEEE.
EV= Equivalence value for the renewable fuel per Sec.  80.1115.
V<INF>s</INF> = Standardized volume of the batch of renewable fuel 
at 60 [deg]F, in gallons.

    (7) Standardization of volumes. In determining the standardized 
volume of a batch of renewable fuel for purposes of generating 
standard-value batch-RINs or extra-value batch-RINs, pursuant to 
paragraphs (c)(5) and (c)(6) of this section, the batch volumes shall 
be adjusted to a standard temperature of 60 [deg]F.
    (i) For ethanol, the following formula shall be used:

V<INF>s,e</INF> = V<INF>a,e</INF> * (-0.0006301 x T + 1.0378)

Where:

V<INF>s,e</INF> = Standardized volume of ethanol at 60 [deg]F, in 
gallons.
V<INF>a,e</INF> = Actual volume of ethanol, in gallons.
T = Actual temperature of the batch, in [deg]F.

    (ii) For biodiesel (mono alkyl esters), the following formula shall 
be used:

V<INF>s,b</INF> = V<INF>a,b</INF> * (-0.0008008 x T + 1.0480)

Where:

V<INF>s,b</INF> = Standardized volume of biodiesel at 60 [deg]F, in 
gallons.
V<INF>a,b</INF> = Actual volume of biodiesel, in gallons.
T = Actual temperature of the batch, in [deg]F.

    (iii) For other renewable fuels, an appropriate formula commonly 
accepted by the industry shall be used to standardize the actual volume 
to 60 [deg]F.
    (d) Assignment of batch-RINs to batches. (1) The producer or 
importer of a batch of renewable fuel must assign standard-value RINs 
to the batch of renewable fuel that those batch-RINs represent.
    (2) The producer or importer of a batch of renewable fuel may 
assign extra-value batch-RINs to the batch of renewable fuel that those 
batch-RINs represent.
    (3) A batch-RIN is assigned to a batch when the batch-RIN is 
recorded in a prominent location on a product transfer document 
assigned to that batch of renewable fuel per Sec.  80.1153.


Sec.  80.1127  How are RINs used to demonstrate compliance?

    (a) Renewable volume obligations. (1) Except as specified in 
paragraph (b) of this section, each party that is obligated to meet the 
Renewable Volume Obligation under Sec.  80.1107, or an exporter of 
renewable fuels, must demonstrate that it has acquired sufficient RINs 
to satisfy the following equation:

([Sigma]RINVOL)<INF>i</INF> + ([Sigma]RINVOL)<INF>i-1</INF> = 
RVO<INF>i</INF>

Where:

([Sigma]RINVOL)<INF>i</INF> = Sum of all acquired gallon-RINs that 
were generated in year i and are being applied towards the 
RVO<INF>i</INF>, in gallons.
([Sigma]RINVOL)<INF>i-1</INF> = Sum of all acquired gallon-RINs that 
were generated in year i-1 and are being applied towards the 
RVO<INF>i</INF>, in gallons.

[[Page 55641]]

RVO<INF>i</INF> = The Renewable Volume Obligation for the obligated 
party or renewable fuel exporter for calendar year i, in gallons.

    (2) For compliance for calendar years 2009 and later, the value of 
([Sigma]RINVOL)<INF>i-1</INF> may not exceed a value determined by the 
following inequality:

([Sigma]RINVOL)<INF>i-1</INF> <= 0.20 * RVO<INF>i</INF>

Where:

([Sigma]RINVOL)<INF>i-1</INF> = Sum of all acquired gallon-RINs that 
were generated in year i-1 and are being applied towards the 
RVO<INF>i</INF>, in gallons.

    (3) RINs may only be used to demonstrate compliance with the RVO 
for the calendar year in which they were generated or the following 
calendar year. RINs used to demonstrate compliance in one year cannot 
be used to demonstrate compliance in any other year.
    (4) A party may acquire a RIN only if that RIN is obtained in 
accordance with Sec. Sec.  80.1128 and 80.1129.
    (5) Gallon-RINs that can be used for compliance with the RVO shall 
be calculated from the following formula:
RINVOL = EEEEEE - SSSSSS + 1

Where:

RINVOL = Gallon-RINs associated with a batch-RIN, in gallons.
EEEEEE = Batch-RIN component identifying the last gallon associated 
with the batch of renewable fuel that the batch-RIN represents.
SSSSSS = Batch-RIN component identifying the first gallon associated 
with the batch of renewable fuel that the batch-RIN represents.

    (b) Deficit carryovers. (1) An obligated party or an exporter of 
renewable fuel that fails to meet the requirements of paragraph (a)(1) 
of this section for calendar year i is permitted to carry a deficit 
into year i + 1 under the following conditions:
    (i) The party did not carry a deficit into calendar year i from 
calendar year i-1.
    (ii) The party subsequently meets the requirements of paragraph 
(a)(1) of this section for calendar year i+1.
    (2) A deficit is calculated according to the following formula:

D<INF>i</INF> = RVO<INF>i</INF> - [([Sigma]RINVOL)<INF>i</INF> + 
([Sigma]RINVOL)<INF>i</INF><INF>-</INF>1]

Where:

D<INF>i</INF> = The deficit generated in calendar year i that must 
be carried over to year i+1 if allowed pursuant to paragraph 
(b)(1)(i) of this section, in gallons.
RVO<INF>i</INF> = The Renewable Volume Obligation for the obligated 
party or renewable fuel exporter for calendar year i, in gallons.
([Sigma]RINVOL)<INF>1</INF> = Sum of all acquired gallon-RINs that 
were generated in year i and are being applied towards the 
RVO<INF>i</INF>, in gallons.
([Sigma]RINVOL)<INF>i</INF><INF>-</INF>1 = Sum of all acquired 
gallon-RINs that were generated in year i-1 and are being applied 
towards the RVO<INF>i</INF>, in gallons.

Sec.  80.1128  General requirements for RIN distribution.

    (a) RINs assigned to batches of renewable fuel. (1) Except as 
provided in Sec.  80.1129 and paragraph (a)(3) of this section, as 
title to a batch of renewable fuel is transferred from one party to 
another, a batch-RIN that has been assigned to that batch according to 
Sec.  80.1126(d) must remain assigned to an equivalent renewable fuel 
volume having the same equivalence value.
    (i) A batch-RIN assigned to a batch shall be identified on product 
transfer documents representing the batch pursuant to Sec.  80.1153.
    (ii) Any documentation used to transfer custody of or title to a 
batch from one party to another must identify the batch-RINs assigned 
to that batch.
    (2) If two or more batches of renewable fuel are combined into a 
single batch, then all the batch-RINs assigned to all the batches 
involved in the merger shall be assigned to the final combined batch.
    (3) If a batch of renewable fuel is split into two or more smaller 
batches, any batch-RINs assigned to the parent batch must likewise be 
split and assigned to the daughter batches.
    (i) If the Equivalence Value for the renewable fuel in the parent 
batch is equal to or greater than 1.0, then there shall be at least one 
gallon-RIN for every gallon in each of the daughter batches.
    (ii) If the Equivalence Value for the renewable fuel in the parent 
batch is less than 1.0, then the ratio of gallon-RINs to gallons in the 
parent batch shall be preserved in all daughter batches.
    (iii) For purposes of this paragraph (a)(3), the volume of each 
parent and daughter batch shall be standardized to 60 [deg]F pursuant 
to Sec.  80.1126(c)(7).
    (b) RINs not assigned to batches of renewable fuel. (1) Unassigned 
RIN means one of the following:
    (i) It is a RIN that contains a K value identifying it as an extra-
value RIN and was not assigned to a batch of renewable fuel by the 
producer or importer of that batch; or
    (ii) It is a RIN that was separated from the batch to which it was 
assigned in accordance with Sec.  80.1129.
    (2) Any party that has registered pursuant to Sec.  80.1150 can 
hold title to an unassigned RIN.
    (3) Unassigned RINs can be transferred from one party to another 
any number of times.
    (4) An unassigned batch-RIN can be divided by its holder into two 
batch-RINs, each representing a smaller number of gallon-RINs if all of 
the following conditions are met:
    (i) All RIN components other than SSSSSS and EEEEEE are identical 
for the parent and daughter RINs.
    (ii) The sum of the gallon-RINs associated with the two daughter 
batch-RINs is equal to the gallon-RINs associated with the parent 
batch.


Sec.  80.1129  Requirements for separating RINs from batches.

    (a)(1) Separation of a RIN from a batch means termination of the 
assignment of the RIN from a batch of renewable fuel.
    (2) A RIN that has been assigned to a batch of renewable fuel 
according to Sec.  80.1126(d) may be separated from a batch only under 
one of the following conditions:
    (i) A party that is an obligated party according to Sec.  80.1106 
may separate any RINs that have been assigned to a batch if they own 
the batch.
    (ii) Except as provided in paragraph (a)(2)(v) of this section, any 
party that owns a batch of renewable fuel shall have the right to 
separate any RINs that have been assigned to that batch once the batch 
is blended with gasoline or diesel to produce a motor vehicle fuel.
    (iii) Any party that exports a batch of renewable fuel shall have 
the right to separate any RINs that have been assigned to the exported 
batch.
    (iv) Except as provided in paragraph (a)(2)(v) of this section, any 
renewable fuel producer that owns a batch of renewable fuel shall have 
the right to separate any RINs that have been assigned to that batch if 
the renewable fuel is designated as motor vehicle fuel in its neat form 
and is used as motor vehicle fuel in its neat form.
    (v) RINs assigned to batches of biodiesel (mono-alkyl esters) can 
only be separated from those batches once the biodiesel is blended into 
diesel fuel at a concentration of 80 volume percent biodiesel or less.
    (b) Upon separation from its associated batch, a RIN shall be 
removed from all documentation that:
    (1) Is used to identify custody or title to the batch; or
    (2) Is transferred with the batch.
    (c) RINs that have been separated from batches of renewable fuel 
become unassigned RINs subject to the provisions of Sec.  80.1128(b).


Sec.  80.1130  Requirements for exporters of renewable fuels.

    (a)(1) Any party that exports any amount of renewable fuel shall 
acquire sufficient RINs to offset a Renewable Volume Obligation 
representing the exported renewable fuel.

[[Page 55642]]

    (2) Only exporters located in the applicable region described in 
Sec.  80.1126(a) are subject to the requirements of this section.
    (b) Renewable Volume Obligations. An exporter of renewable fuel 
shall determine its Renewable Volume Obligation from the volumes of the 
batches exported.
    (1) A renewable fuel exporter's total Renewable Volume Obligation 
shall be calculated according to the following formula:

RVO<INF>i</INF> = [Sigma](VOL<INF>k</INF> * EV<INF>k</INF>) + 
D<INF>i-1</INF>

Where:

k = Batch.
RVO<INF>i</INF> = The Renewable Volume Obligation for the exporter 
for calendar year i, in gallons of renewable fuel.
VOL<INF>k</INF> = The standardized volume of batch k of exported 
renewable fuel, in gallons.
EV<INF>k</INF> = The equivalence value for batch k.
D<INF>i</INF><INF>-1</INF> = Renewable fuel deficit carryover from 
the previous year, in gallons.

    (2)(i) For exported batches of renewable fuel that have assigned 
RINs, the equivalence value may be determined from the RR component of 
the RIN.
    (ii) If a batch of renewable fuel does not have assigned RINs but 
its equivalence value may nevertheless be determined pursuant to Sec.  
80.1115(d) based on its composition, then the appropriate equivalence 
value shall be used in the calculation of the exporter's Renewable 
Volume Obligation.
    (iii) If the equivalence value for a batch of renewable fuel cannot 
be determined, the value of EV<INF>k</INF> shall be 1.0.
    (3) If the exporter of a batch of renewable fuel is also the 
producer of that batch, and no RIN was generated to represent that 
batch, then the volume of that batch shall be excluded from the 
calculation of the Renewable Volume Obligation.
    (c) Each exporter of renewable fuel must demonstrate compliance 
with its RVO using RINs it has acquired pursuant to Sec.  80.1127.


Sec.  80.1131  Treatment of invalid RINs.

    (a) Invalid RINs. An invalid RIN is a RIN that:
    (1) Is a duplicate of a valid RIN;
    (2) Was based on volumes that have not been standardized to 60 
[deg]F;
    (3) Has expired;
    (4) Was based on an incorrect equivalence value; or
    (5) Was otherwise improperly generated.
    (b) In the case of RINs that have been determined to be invalid, 
the following provisions apply:
    (1) Invalid RINs cannot be used to achieve compliance with the 
transferee's Renewable Volume Obligation, regardless of the 
transferee's good faith belief that the RINs were valid.
    (2) The refiner or importer who used the invalid RINs, and any 
transferor of the invalid RINs, must adjust their records, reports, and 
compliance calculations as necessary to reflect the deletion of invalid 
RINs.
    (3) Any valid RINs remaining after deleting invalid RINs, and after 
an obligated party applies valid RINs as needed to meet the RVO at the 
end of the compliance year, must first be applied to correct the 
invalid transfers before the transferor trades or banks the RINs.
    (4) In the event that the same RIN is transferred to two or more 
parties, the RIN will be deemed to be invalid, and any party to any 
transfer of the invalid RIN will be deemed liable for any violations 
arising from the transfer or use of the invalid RIN.
    (5) A RIN will not be deemed invalid where it can be determined 
that the RIN was properly created and transferred.

Sec.  80.1141  Small refinery exemption.

    (a)(1) Pursuant to Sec.  80.1107(d), gasoline produced by a refiner 
at a small refinery is qualified for an exemption from the renewable 
fuels standards of Sec.  80.1105 if that refinery meets the definition 
of a small refinery under Sec.  80.1101(i) for calendar year 2004.
    (2) This exemption shall apply through December 31, 2010, unless a 
refiner chooses to opt-in to the program requirements of this subpart 
(per paragraph (g) of this section) prior to this date.
    (b)(1) To apply for an exemption under this section, a refiner must 
submit an application to EPA containing the following information:
    (i) The annual average aggregate daily crude oil throughput for the 
period January 1, 2004, through December 31, 2004 (as determined by 
dividing the aggregate throughput for the calendar year by the number 
365);
    (ii) A letter signed by the president, chief operating or chief

exemption under this subpart.
    (m) Additional attest requirements for importers of RFS-FRGAS. 
Importers of RFS-FRGAS, for each annual compliance period, must arrange 
to have an attest engagement performed of the underlying documentation 
that forms the basis of any report or document required under this 
subpart. The attest engagement must comply with the procedures and 
requirements that apply to importers under Sec. Sec.  80.125 through 
80.130, and other applicable attest engagement provisions, and must be 
submitted to the Administrator of EPA by August 31 of each year for the 
prior annual compliance period. The following additional procedures 
shall be carried out for any importer of RFS-FRGAS.
    (1) Obtain listings of all tenders of RFS-FRGAS. Agree the total 
volume of tenders from the listings to the gasoline inventory 
reconciliation analysis in Sec.  80.128(b), and to the volumes 
determined by the third party under paragraph (d) of this section.
    (2) For each tender under paragraph (m)(1) of this section, where 
the gasoline is loaded onto a marine vessel, report as a finding the 
name and country of registration of each vessel, and the volumes of 
RFS-FRGAS loaded onto each vessel.
    (3) Select a sample from the list of vessels identified in 
paragraph (m)(2) of this section used to transport RFS-FRGAS, in 
accordance with the guidelines in Sec.  80.127, and for each vessel 
selected perform the following:
    (i) Obtain the report of the independent third party, under 
paragraph (d) of this section, and of the United States importer under 
paragraph (k) of this section.
    (A) Agree the information in these reports with regard to vessel 
identification and gasoline volume.
    (B) Identify, and report as a finding, each occasion the load port 
and port of entry volume results differ by more than the amount allowed 
in paragraph (e) of this section, and determine whether the foreign 
refiner adjusted its refinery calculations as required in paragraph (e) 
of this section.
    (ii) Obtain the documents used by the independent third party to 
determine transportation and storage of the RFS-FRGAS from the refinery 
to the load port, under paragraph (d) of this section. Obtain tank 
activity records for any storage tank where the RFS-FRGAS is stored, 
and pipeline activity records for any pipeline used to transport the 
RFS-FRGAS prior to being loaded onto the vessel. Use these records to 
determine whether the RFS-FRGAS was produced at the refinery that is 
the subject of the attest engagement, and whether the RFS-FRGAS was 
mixed with any Non-RFS-FRGAS or any RFS-FRGAS produced at a different 
refinery.
    (4) Select a sample from the list of vessels identified in 
paragraph (m)(2) of this section used to transport RFS-FRGAS, in 
accordance with the guidelines in Sec.  80.127, and for each vessel 
selected perform the following:
    (i) Obtain a commercial document of general circulation that lists 
vessel arrivals and departures, and that includes the port and date of 
departure of the vessel, and the port of entry and date of arrival of 
the vessel.
    (ii) Agree the vessel's departure and arrival locations and dates 
from the independent third party and United States importer reports to 
the information contained in the commercial document.
    (5) Obtain separate listings of all tenders of RFS-FRGAS, and 
perform the following:
    (i) Agree the volume of tenders from the listings to the gasoline 
inventory reconciliation analysis in Sec.  80.128(b).
    (ii) Obtain a separate listing of the tenders under this paragraph 
(m)(5) where the gasoline is loaded onto a marine vessel. Select a 
sample from this listing in accordance with the guidelines in Sec.  
80.127, and obtain a commercial document of general circulation that 
lists vessel arrivals and departures, and that includes the port and 
date of departure and the ports and dates where the gasoline was off 
loaded for the selected vessels. Determine and report as a finding the 
country where the gasoline was off loaded for each vessel selected.
    (6) In order to complete the requirements of this paragraph (m) an 
auditor shall:
    (i) Be independent of the foreign refiner or importer;
    (ii) Be licensed as a Certified Public Accountant in the United 
States and a citizen of the United States, or be approved in advance by 
EPA based on a demonstration of ability to perform the procedures 
required in Sec. Sec.  80.125 through 80.130 and this paragraph (m); 
and
    (iii) Sign a commitment that contains the provisions specified in 
paragraph (f) of this section with regard to activities and documents 
relevant to compliance

with the requirements of Sec. Sec.  80.125 through 80.130 and this 
paragraph (m).
    (n) Withdrawal or suspension of foreign refiner status. EPA may 
withdraw or suspend a foreign refiner's small refinery or small refiner 
exemption where--
    (1) A foreign refiner fails to meet any requirement of this 
section;
    (2) A foreign government fails to allow EPA inspections as provided 
in paragraph (f)(1) of this section;
    (3) A foreign refiner asserts a claim of, or a right to claim, 
sovereign immunity in an action to enforce the requirements in this 
subpart; or
    (4) A foreign refiner fails to pay a civil or criminal penalty that 
is not satisfied using the foreign refiner bond specified in paragraph 
(g) of this section.
    (o) Additional requirements for applications, reports and 
certificates. Any application for a small refinery or small refiner 
exemption, alternative procedures under paragraph (l) of this section, 
any report, certification, or other submission required under this 
section shall be--
    (1) Submitted in accordance with procedures specified by the 
Administrator, including use of any forms that may be specified by the
