201 4 Standards For The Renewable Fuel Standard Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: Under section 211(o) of the Clean Air Act, the Environmental Protection Agency is required to set the renewable fuel percentage standards each November for the following year. Today’s action proposes the annual percentage standards for cellulosic biofuel, biomass

- based diesel, advanced biofuel, and renewable fuels that would apply to all motor vehicle gasoline and diesel produced or imported in the year 201 4 . For cellulosic biofuel, the statu t e specifies that EPA is to project the volume of production and must base the cellulosic biofuel standard on projected available volume if it is less than the applicable volume set forth in the Act. Today

EPA is proposing a cellulosic biofuel volume for 201 4 that is below the applicable volume specified in the Act. The statute also provides EPA the discretion to adjust the volumes of advanced biofuel and total renewable fuel under certain conditions. Relying on its Clean Air Act waiver authorities, EPA is proposing to adjust the applicable volumes of advanced biofuel and

total renewable fuel to address projected availability of qualifying renewable fuels and

limitations in the volume of ethanol that can be consumed in gasoline given practical cons traints on the supply of higher ethanol blends to the vehicles that can use them and other limits on ethanol blend levels in gasoline. These adjustments are intended to put the program on a manageable trajectory while supporting growth in renewable fuels over time. Finally, the statute requires EPA to determine the applicable volume of biomass

- based diesel to be used in setting annual percentage standards under the renewable fuel standard program for years after 2012. EPA is proposing the applicable volu me of biomass

- based diesel that would apply in 2014 and

2015

. EPA is requesting comment on a variety of alternative approaches and on a range of inputs and methodologies relevant for setting the applicable standards.

DATES: Comments must be received on or before [ insert date 60 days after date of publication in the Federal Register ]. Hearing : We intend to hold a hearing. Details of the location and date will be provided in a separate notice.

Page 7 of 111 I. Executive Summary

The Renewable F uel Standard (RFS) program began in 2006 pursuant to the requirements in Clean Air Act (CAA) section 211(o) which w as added through the Energy Policy Act of 2005 (EPAct). The statutory requirements for the RFS program were subsequently modified through

th e Energy Independence and Security Act of 2007 (EISA), resulting in the publication of major revisions to the regulatory requirements on March 26, 2010 1

.

The national volumes of renewable fuel to be used under the RFS program each year (absent an adjus tment or waiver by EPA) are specified in CAA section 211(o)(2). The volumes

for 201 4 are shown in Table I

- 1. Note that cellulosic biofuel and biomass

- based diesel categories are nested within advanced biofuel, which is itself nested within the renewable fuel

category.

Table I

- 1 Required Applicable Volumes in Billion Gallons (bill gal) in the Clean Air Act for 201 4

Cellulosic biofuel 1.75 a

Biomass

- based diesel ≥1.0 b

Advanced biofuel 3 .75 a

Renewable fuel 18.15 a

a Ethanol

- equivalent volume

b Actual volume

. The ethanol

- equivalent volume

would be 1.5 if biodiesel is used to meet this requirement

.

Under the RFS program, EPA is required to determine and publish annual percentage standards for each compliance year by November 30 of the previous year. The percentage standards are calculated so as to ensure use in transportation fuel of the national “applicable volumes” of four types of biofuel (cellulosic biofuel, biomass

- based diesel, advanced biofuel, and total renewable fuel) that are either set forth in the Clean Air Act or established by EPA in accordance with the Act’s requirements. The percentage standards are used by obligated parties (generally, producers and importers of transportation fuel) to calculate their individual compliance obl igations. The percentage standards are applied to the volume of non

- renewable transportation fuel that each obligated party produces or imports during the specified calendar year to determine the volumes of renewable fuel that must be used as transportati on fuel, heating oil, or jet fuel.

As required by statute, we are proposing to establish the volume for cellulosic biofuel based on projected availability of such fuel

– which is below the statutory target for 2014. In

addition , w e have evaluated the availability of qualifying renewable fuels and factors that in some cases limit supplying those fuels to the vehicles and equipment that can consume them, including the set of factors referred to as the ethanol blendwall. Based on this evaluation we

believe that adjustments to the volumes of advanced biofuel and total renewable fuel required under the statute are warranted for 2014 due to an inadequate domestic supply of these fuels (see

1 75 FR 14670*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 8 of 111 Section IV.A fo r further detail). We are also proposing to maintain the same volume for

biomass

- based diesel for 2014 and 2015 as was adopted for 2013. The volumes that we are proposing for 2014 , as well as the ranges on which we are seeking comment, ar e shown below. With the exception of the volume requirement for cellulosic biofuel, the proposed volumes correspond to the preferred approach described in today’s proposal, but we discuss and are seeking comment on alternative approaches as well

.

- 15.52 bill gal

a All volumes are ethanol

- equivalent, except for biomass

- based diesel which is actual.

b EPA is requesting comment on alternative approaches and higher volumes.

Section II contains a detailed discussion of the basis for our proposed volume of cellulosic

biofuel for 2014, Section III contains a detailed discussion of the basis for our proposed volume

of biomass

- based diesel for 2014 and 2015, and Section IV contain s a detailed discussion of the basis for our proposed volumes , as well as alternative potential approaches on which we are requesting comment, for advanced biofuel and total renewable fuel for 2014.

In developing this proposal, we have been cognizant tha t Congress anticipated and intended the RFS program to promote substantial, sustained growth in biofuel production and consumption

– beyond the levels that have been achieved to date. Although current gasoline demand and forecasts of future gasoline deman d have decreased since EISA’s enactment in 2007, EPA continues to support the objective of continued growth in renewable fuel production and consumption, as well as the central policy goals underlying the RFS program: reductions in greenhouse gas emissions , enhanced energy security, economic development, and technological innovation. The approach reflected in today’s proposal is consistent with those objectives and is intended to put the RFS program on a manageable trajectory while supporting continued gro wth in renewable fuels over time. As emphasized throughout the proposal, we are seeking comment and information on a variety of alternative approaches as well as ranges of inputs and methodologies relevant to setting these standards, and look forward to e ngagement with stakeholders on all aspects of the proposal.

A. Purpose of This Action

EPA is today proposing annual volume requirements for obligated parties for cellulosic biofuel, biomass

- based diesel, advanced biofuel, and total renewable fuel for 2014 . Table I.A

211(o)(7)(A) EPA may waive any portion of the s tatutory

volume requirements if implementation of those requirements would severely harm the economy or environment of a State, region,

or the United States

, or there is an inadequate domestic supply

.

Under the statute, EPA must annually determine the projected volume of cellulosic biofuel production for the following year. If the projected volume of cellulosic biofuel production is less than the applicable volume specified in section 211(o)(2)(B)(i)(III) of the statute, EPA must lower the applicable v olume used to set the annual cellulosic biofuel percentage standard to the projected volume of production available during the year . In today's proposed rule , we present our analysis of cellulosic biofuel production and projected volume for

2014

. T his an alysis is based on our evaluation of individual producers’ production plans and progress to date following discussions with cellulosic biofuel producers, the Energy Information Administration (EIA)

, the Department of Agriculture (USDA), and the Department of Energy*** EO12866 Review

Page 10 of 111 (DOE), and includes an assessment of the probabilities associated with production schedules from each of these producers.

While CAA section 211(o)(2)(B) specifies the volumes of biomass

- based diesel to be used in the RFS program through year 2012, it directs the EPA to establish the applicable

volume of biomass

- based diesel for years after 2012. The statute also lists the factors that must be considered in this determination. In today's action we are proposing volume requirements for

biomass

- based diesel for both 2014 and 2015

.

There are two different authorities in the statute that permit EPA to reduce volumes of advanced biofuel and total renewable fuel below the volumes specified in the statute. W hen we lower the applicable volume of ce llulosic biofuel below the volume specified in CAA 211(o)(2)(B)(i)(III), we also have the authority to reduce the applicable volumes of advanced biofuel and total renewable fuel by the same or a lesser amount. We can also reduce the applicable volumes of advanced biofuel or total renewable fuel under the general waiver authority provided at CAA 211(o)(7)(A) under certain conditions. Today's proposal uses a

combination of these two authorities to reduce volumes of both advanced biofuel and total

renewable fuel to address two important realities:

• Limitations in the volume of ethanol that can be consumed in gasoline given practical constraints on the supply of higher ethanol blends to the vehicles that can use them

and other limits on ethanol blend levels in gasoline

– a set of factors commonly

referred to as the ethanol "blendwall"

• Limitations in the ability of the industry to produce sufficient volumes of qualifying

renewable fuel

As described in detail in Section IV, t oday's action lays out a framewo rk for determining the applicable volume requirements that addresses these two realities. We are proposing to use this framework to establish the volume requirements in 2014. As described in more detail in Section IV.E, we believe that this frame work would also be appropriate for later years, subject to adjustments made in the course of the rulemaking process and taking into account the specific facts about the availability of renewable fuels at the time of the final rulemaking.

I n today's propo sed rule we have also provided the annual percentage standards (shown in Section I.B.4 below) that would apply to all producers and importers of gasoline and diesel in

2014 . The percentage standards , which establish the legal requirement for the obligated parties,

are based on the 2014 applicable volumes that we project for the four types of renewable fuel

and a projection of volumes of gasoline and diesel consumption in 2014 from the Energy Information Administration (EIA).

B. Summary of Major Provisions in This Notice

1. Cellulosic Biofuel Volume for 2014*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 11 of 111 The cellulosic biofuel industry continues to transition from research and development (R&D) and pilot scale to commercial scale facilities, leading to significant increases in production c apacity. RIN generation from the first commercial scale cellulosic biofuel facility began in March 2013. 2 A second facility began producing fuel in July 2013 with several others expected to follow in 2014. Based on information we have collected from the se companies and discussions with EIA, we have identified five companies we expect to produce cellulosic biofuel

in 2014. There are an additional three companies that may be in a position to produce cellulosic biofuel if additional pathways are approved b y EPA. Each of the relevant facilities is listed in

Table I.B.1

- 1 along with our estimate of their projected 2014 volume. Based on the information we have received from these companies, our conversations with other government agencies, and EPA's own engi neering judgment we are projecting that 8

- 30 million ethanol

- equivalent gallons

of cellulosic biofuel will be available in 2014. This range does not account for the estimate that EIA is required to provide to EPA containing estimates of the volume of cellulosic biofuel projected to be sold or introduced into commerce in 2014. Th e projected range also does not include any volume from facilities that could use pathways which have not yet been approved. If production volumes from these facilities were included, we would project a production range of

5 3

- 8 3 million ethanol

- equivalent gallons.

As part of estimat ing the volume of cellulosic biofuel that would be made available in the

U.S. in 2014 , we researched all potential production sources by company and facility. This included sources that were still in the planning stages, those that were under construction, and those that are already producing some volume of cellulosic ethanol, cellulosic diesel, or some other type of cellulosic biofuel. Facilities primarily focused on research and development were

not the focus of our assessment as production from these facilities represents very small volumes of cellulosic biofuel, and these facilities typically have not generated RINs for the fuel they have already produced. From this universe of potential cellulosic biofuel sources

, we identified the

subset that is expected to produce commercial volumes of qualifying cellulosic biofuel for use in

2014 . To arrive at a projected volume for each facility , we developed company specific projections based on discussions with cellulosic biofuel producers, EIA, USDA, and DOE, and

on factors such as the current and expected state of funding, the status of the technology utilized,

progress towa

rds construction and production goals, and other significant factors that could potentially impact fuel production or the ability of the produced fuel to qualify for cellulosic

biofuel Renewable Identification Numbers (RINs) in 2014 . Further discussion of these factors

can be found in Section II.B.

In our assessment we focused on domestic sources of cellulosic biofuel. At the time of this proposed rule no internationally

- based cellulosic biofuel production facilities have registered under the RFS progra m and therefore no volume from international producers has been included in our projections for 2014

.

2 A RIN is unique number generated by the producer and assigned to each gallon of a qualifying renewable fuel under the RFS program, and is used by refiners and importers to demonstrate compliance with the volume requirements under the program.*** EO12866 Review

In projecting the actual volume of cellulosic biofuel that will be available for use in 2014,

we have taken into account v ariation in expected start

- up times, along with the facility production capacities, company production plans, the progress made in 2013, expected production distribution and a variety of other factors. We used this information to determine the most likely production ranges for each of the individual companies and a production probability distribution within the range. We then used a Monte Carlo simulation to aggregate the individual ranges into a production pr ojection for the cellulosic biofuel industry as a whole in 2014. We believe this method results in a projected production range that better represents our expectations for cellulosic biofuel production in 2014 than simply adding the low and high end of th e production ranges from each of the individual companies. Section II discusses in greater detail our projections of cellulosic biofuel in 2014 and the companies we expect to produce this

volume.

In response to a recent court decision, we are also pro posing to rescind the cellulosic biofuel standards for 2011. In January 2013, the United States Court of Appeals for the District of Columbia Circuit issued a decision interpreting the statutory requirements for EPA’s cellulosic biofuel projections, in th e context of considering a challenge to the 2012 cellulosic

biofuel standard. The Court found that in establishing the applicable volume of cellulosic biofuel for 2012, EPA had used a methodology in which “the risk of overestimation [was] set deliberately to outweigh the risk of underestimation.” The Court held EPA’s action to be inconsistent with the statute because EPA had failed to apply a “neutral methodology” aimed at*** EO12866 Review

Page 13 of 111 providing a prediction of “what will actually happen,” as required by the statute. As a result of this ruling, the Court vacated the 2012 cellulosic biofuel standard. See API v. EPA , 706 F.3d 474 (D.C. Cir. 2013). EPA later removed the 2012 cellulosic biofuel requirement from the regulations. 3 Since we used essentially the same methodology to develop the 2011 cellulosic biofuel standard as we did to develop the 2012 standard, we believe it would be appropriate to rescind the 2011 cellulosic biofuel standard as well and accordingly are proposin g to do so in today’s action. The money paid by obligated parties to purchase cellulosic waiver credits to comply with the 2011 cellulosic biofuel standard would be refunded if this action is finalized. 4

2. Biomass

- Based Diesel Requirement in 2014 and 2015

While section 211(o)(2)(B) specifies the volumes of biomass

- based diesel through year 2012, it directs the EPA to establish the applicable volume of biomass

- based diesel for years after 2012. Moreover, the statute requires that we finalize these bi omass

- based diesel volume requirements no later than 14 months before the first year for which that volume requirement will apply. We did not propose a volume requirement for biomass

- based diesel in the February 7, 2013 Notice of Proposed Rulemaking becau se at that time we were still evaluating the potential market impacts of current production levels. In order to provide sufficient time for this evaluation, as well as the other analyses we are required to conduct, we delayed our proposal for

the 2014 vol ume requirement for biomass

- based diesel.

In today's action we are proposing to maintain the applicable volume of 1.28 bill gallons

for biomass

- based diesel for both 2014 and 2015. As required by the statute when setting

biomass

- based diesel volume requirements for years after 2012, our proposal is based on a consideration of the factors specified in the statute, including biodiesel production, consumption, infrastructure, climate change, energy security, the agricultural sector, air quality, and oth ers. Section III provides additional discussion of our assessment of the proposed volume of 1.28 bill gal of biomass

- based diesel.

. Advanced Biofuel and Total Renewable Fuel in 2014

Since the RFS2 program began in 2010, EPA has considered reduction s in advanced biofuel and total renewable fuel authorized under the cellulosic waiver provisions of 211(o)(7)(D)(i). In the past we have focused primarily on the availability of advanced biofuels in determining whether reductions in the required volume of cellulosic biofuel should be accompanied by reductions in the required volumes of advanced biofuel and total renewable fuel.

The total volume of renewable fuel in the form of ethanol that could reasonably be available and supplied to vehicles as either E 10 or higher ethanol blends given various constraints , was not a limiting factor for years prior to 2014. However, for 2014 and later years, the total volume of ethanol that can be consumed, and the total volume of non

- ethanol renewable fuels that could

r easonably be available, are together expected to be less than the volume requirements

4 In 2011 obligated parties purchased 4,248,388 cellulosic biofuel waiver credits at a price of $1.13 per gallon

Page 14 of 111 established in EISA for advanced biofuel and total renewable fuel. Therefore, we are proposing reductions in the volume requirements for these categories of renewable fu el to address these

concerns.

W e evaluated three potential approaches for reducing the applicable volume requirements

for advanced biofuel and total renewable fuel. Each of these approaches would require use of a combination of the cellulosic and genera l waiver authorities at 211(o)(7)(D)(i) and 211(o)(7)(A)

, respectively, to address supply concerns associated with the blendwall. The three approaches differ primarily with regard to how the advanced biofuel requirement would be adjusted using

these autho rities. The first approach would lower the statutory volumes for advanced biofuels only to the extent that additional volumes are not projected to be available; the general waiver authority would be used to ensure that the total volume of renewable fuel w ould address supply

concerns associated with the blendwall . The second approach would make reductions in advanced biofuel and total renewable fuel that are equal to the proposed reductions in cellulosic

biofuel and would use the general waiver authority t o make further reductions to the total renewable fuel requirement necessary to address the blendwall

.

The third approach that we evaluated, and the one that we are proposing today, includes both a consideration of the capability of the relevant industr ies to make qualifying renewable fuels available, either through domestic production or importation, and also the capability of the relevant industries to ensure that those renewable fuels are used as transportation fuel, heating oil, or jet fuel. 5 The us e of renewable fuels includes a consideration of the infrastructure available for distributing, blending, and dispensing renewable fuels, as well as appropriate vehicles in the fleet that can consume various renewable fuels, such as flex

- fuel vehicles (FFV s). Our proposed framework for addressing both availability of qualifying renewable fuels and constraints on their consumption would make use of a combination of the cellulosic waiver authority at 211(o)(7)(D)(i) and the general waiver authority at 211(o) (7)(A). As described in detail in Section IV.A.2, we interpret the term "inadequate domestic supply" as it is used under the general waiver authority to include consideration of factors that affect consumption of

renewable fuel. We believe the framework being proposed today best approximates the multiple goals that Congress intended in the RFS program, and we would intend this framework to apply not just to 2014, but to later years as well. However, we are soliciting comment on alternative approaches as well. We discuss the proposed framework and the alternative approaches in

Section IV.

We believe that our proposed framework for determining appropriate volumes of total renewable fuel and advanced biofuel would simultaneously address the ethanol blen dwall and limitations in availability of qualifying renewable fuels. For total renewable fuel, we would project the volume of ethanol that could reasonably be consumed as E10 and higher ethanol blends, and would add to that the volume of all non

- ethanol r enewable fuels that could reasonably be expected to be available. For advanced biofuel, we would sum the ethanol

equivalent volumes of the cellulosic biofuel requirement, the biomass

- based diesel requirement,

and the additional non

- ethanol advanced biofue ls that could reasonably be expected to be

5 While the fuels that are subject to the percentage standards are currently only non

- renewable gasoline and diesel, renewable fuels that are valid for compliance with the standards include those used as transportation fuel, heating oil, or jet fuel.*** EO12866 Review

. Propos ed Annual Percentage Standards for 2014

The renewable fuel standards are expressed as a volume percentage and are used by each refiner, blender

, or importer to determine their renewable fuel volume obligations. The applicable percentages are set so that if each regulated party meets the percentages, and if EIA projections of gasoline and diesel use for the coming year prove to be accurate, then the amount of renewable fuel, cellulosic biofuel, biomass

- based diesel, and advanced biofuel actually used

will meet the volumes required on a nationwide basis.

Four separate percentage standards are required under the RFS program, corresponding to the four separate volume requirements shown in Table I

- 1. The specific formulas we use in calculating the renewable fuel percentage standards are contained in the regulations at 40 CFR §80.1405 and repeated in Section V.B.1. The percentage standards represent the ratio of renewable fuel volume to projected non

- renewable gasoline and diesel volume. The p rojected volume of transportation gasoline and diesel used to calculate the standards in today's proposed rule was derived from EIA projections. The proposed standards for 2014 are shown in Table

I.B. 4

- 2. Detailed calculations can be found in Section V

, including the projected 2014 gasoline

and diesel volumes used

.

Table I.B. 4

- 2 Proposed Percentage Standards for 2014

Cellulosic biofuel 0.010 %

Biomass

- based diesel 1.16 %

Advanced biofuel 1.33 %

Renewable fuel 9. 20 %

C. Volume Requirements for 2015 and Beyond

As highlighted above, EPA continues to support the objective

– reflected in the statute

– of continued growth in renewable fuel production and consumption, as well as the central goals of the RFS program: enhanced energy security and reductions in greenhouse gas emissions. We also recognize that issues concerning the availability of qualifying fuels and the consumption of ethanol will continue to be relevant in 2015 and beyond, particularly in light of projections t hat overall gasoline demand will continue to decline while the statutory volumes for renewable fuel volumes continue to increase. Our objective in this rulemaking is to develop a general approach

for determining appropriate volume requirements that can b e applied not only in 2014, but also for 2015 and beyond . As we consider comments received in response to this NPRM, our intent is to develop an approach that puts the RFS program on a manageable trajectory while supporting continued growth in renewable fuels over time. The proposed approac h described in today's NPRM can and will account for new and improved data and changes in circumstances*** EO12866 Review

Page 16 of 111 over time, including the substantial efforts underway to increase the volume of biofuel produced and consumed in the United States. Many com panies, often supported by various government programs, are continuing to invest in efforts ranging from research and development to the construction of commercial scale facilities resulting in the ongoing growth of next generation

biofuels. Similar effor ts on the part of both public and private sectors are growing the infrastructure to enable expansion in the use of gasoline fuel blends containing greater than 10 percent ethanol. Under the right circumstances, there is substantial potential for continued growth in the use of ethanol and next generation biofuels, both in the near term and into the

future. As both ethanol and non

- ethanol renewable fuel volumes grow, the proposed methodology set forth in today’s proposed rule will incorporate this growth in to the development of the standards for the following year, providing an ongoing incentive for growth of biofuels. We recognize that a number of challenges must be overcome to fully realize the potential that

exists for i ncreas ed production and consumption of renewable fuels in the United States. We also recognize that while the RFS program is a central element of our domestic biofuels policy, a range of other tools, p rograms, and actions have the potential to play an important complementary role. We request information and ideas o n what actions could be taken by the variety of industry and other private stakeholders, as well by the government, to help overcome

the se ch allenges , continue to foster innovation, and minimize the need for adjustments in the

statutory renewable fuel volume requirements in the future.*** EO12866 Review

Page 17 of 111 II. Proposed Cellulosic Biofuel Volume for 201 4

In order to project the volume of cellulosic biofuel production in 201 4 for use in setting

the applicable percentage standard, we considered information we received from EIA and

infor mation we collected from individual facilities that have the potential to produce qualifying volumes for consumption as transportation fuel, heating oil, or jet fuel in the U.S. in 201 4 . This

section describes the volumes that we project will be produced or imported in 201 4 as well as

some of the uncertainties associated with those volumes.

In the past several years the cellulosic biofuel industry has continued to progress. The first cellulosic biofuel RINs under the current RFS regulations were produ ced in 2012 at two

small demonstration scale facilities. During 2013

, the first commercial scale cellulosic biofuel

facilities have successfully complete d commissioning and beg a n fuel production

, and several more large scale commercial production facilities are expected to begin fuel production in 2014. Projected costs for the production of cellulosic biofuels continues to fall as a result of ongoing technology development and operating experience gained from many research and development

and demonstration

- scale facilities across the country. These important advances include higher biofuel yields per ton of feedstock as well as lower enzyme and catalyst costs. As a result of

these advances , the p rojected capital costs and energy costs to produce a gallon of cellulosic biofuel have decreased. New feedstock supply chains, which will be necessary to provide the raw materials for anticipated commercial facilities, have been established, and in severa l cases companies have signed contracts to obtain significant quantities of feedstocks for their first commercial facilities. EPA has also approved new pathways to increase the variety of fuels for which cellulosic RINs can be generated and the feedstocks from which these fuels can be produced. These factors have combined to continue to reduce the perceived technical, financial, and regulatory risks associated with the cellulosic biofuel industry and place the cellulosic biofuel industry on firm ground fo r future growth.

Although the cellulosic biofuel industry faces many challenges and RIN

- generating cellulosic biofuel production continues to be limited, the industry is growing incrementally , both

in the United States and around the world. 6 New faciliti es projected to be brought online in the United States in 2014 would increase the production capacity of the cellulosic industry by approximately 600 percent. The following section discusses the companies the EPA reviewed in the process of projecting cell ulosic biofuel production for use as a transportation fuel in the

United States in 2014. Information on t hese companies form s the basis for our projection that the volume of cellulosic biofuel produced in 2014 is likely to be in the range of 8

- 30 millio n gallons. EPA will continue to monitor the progress of these facilities, as well as any others of which we become aware that have the potential for cellulosic biofuel production in 2014, in order to have the most up to date information possible to set th e cellulosic biofuel standard in the

final rule.

A. Statutory Requirements

, 215,044 RIN s that can be used to fulfill the cellulosic biofuel standard (D3 and D7 RINS) have been generated

Page 18 of 111 The volumes of renewable fuel to be used under the RFS program each year (absent an adjustment or waiver by EPA) are specified in CAA 211(o)(2). For 201 4 , the statute specifies a cellulosic biofuel volume requirement of 1. 75 bill ion gal lons . The statute requires that if EPA

determines , based on EIA’s estimate, that the projected volume of cellulosic biofuel production for the following year is less than the applicable volume EPA is to reduce the applicable volume of cellulosic biofuel to the projected volume available during that calendar year.

In addition, if EPA reduces the required volume of cellulosic biofuel below the level specified in the statute, the Act als o indicates that we may reduce the applicable volumes of advanced biofuels and total renewable fuel by the same or a lesser volume. Our consideration of

the 201 4 volume requirements for advanced biofuels and total renewable fuel is presented in

Section IV

.

B

. Cellulosic Biofuel Volume Assessment for 201 4

In order to project cellulosic biofuel production for 201 4 , we have tracked the progress of several dozen potential cellulosic biofuel production facilities. As for the 2013 annual volumes,

we have f ocused on facilities with the potential to produce commercial volumes of cellulosic biofuel rather than small R&D or pilot scale facilities as the larger commercial scale facilities are much more likely to generate RINs for the fuel they produce and the vo lumes they produce will have a far greater impact on the cellulosic biofuel standard for 2014. From this list of facilities we used publically available information, as well as information provided by DOE , EIA, and USDA, to make a preliminary determinatio n of which facilities are the most likely candidates to produce cellulosic biofuel and generate cellulosic biofuel RINs in 201 4 . Each of these companies was investigated further in order to determine the current status of its facilities and its likely cel lulosic biofuel production and RIN generation volumes for the coming years. Information such as the funding status of these facilities, current status of the production technologies, announced construction and production ramp

- up periods, and annual fuel

p roduction targets were all considered when we spoke with representatives of each company to discuss cellulosic biofuel target production levels for 201 4

. Throughout this process EPA has

been in contact with EIA to discuss relevant information.

For each company included in our 2014 volume projections EPA has established a range of potential production volume such that it is possible, but highly unlikely, that the actual production will be above or below the range. 7 The low end of the range for each comp any is designed to represent the volume of fuel EPA believes each company is likely to produce if they are unable to begin fuel production on their expected start

- up date and/or experience challenges that result in reduced production volumes or a longer th an expected ramp

- up period. Experience to date with cellulosic biofuel production facilities is that historically they have been unable to

achieve announced start

- up dates and production volumes in their first few years of expected production. To project a low end of the range of production volumes, therefore, we must consider the likely minimum volume of fuel new facilities are likely to produce if they experience similar delays and setbacks. The low end of the range for any facilities that have not

Page 19 of 111 yet begun producing cellulosic biofuel is set at zero in our assessment. This reflects the

uncertainties related to these facilities’ start

- up dates, the possibility that any remaining construction and commissioning timelines may be delayed, and the possibil ity that initial fuel volumes are likely to be small.

If a facility has already begun production any uncertainty related to its start

- up date is no longer relevant and the remaining uncertainty primarily relates to the facility’s ability to achieve steady state production and target yields as it progresses towards production rates that reflect the facility’s nameplate capacity. For these facilities, production history is a significant factor in establishing the low end of the projected production range. It is important to note that the low end of the range does not represent a worst

- case scenario. The worst

- case scenario for any of these facilities is zero, as it is always possible that extreme circumstances or natural disasters may result in extended de lays, project cancellation, or liquidation. While not denying this possibility for any of the facilities included in our projections, several have made sufficient progress that we believe a non

- zero value for the low end of the range is appropriate. For these facilities we believe it is highly unlikely that the production volume will fail to exceed the low end of their projected production range in 2014. Further discussion on the basis for the low end of the projected production range for each facility i s included in the company descriptions in the following sections.

To determine the high end of the range of expected production volumes for each company we considered a variety of factors, including company history, expected start

- up date and ramp

- up peri od, facility capacity, and others mentioned above. As a starting point, EPA calculated a production volume using the expected start

- up date and facility capacity assuming

our best

- case scenario benchmark of a six

- month straight

- line ramp

- up period. Any p roduction volumes that exceeded this volume were not considered to be credible, even for the high end of the range of expected production volumes. If the production estimate EPA received from a company was lower than the volume calculated using the method ology above, EPA used the company production targets instead. In some cases these volumes were discounted further based on the history of these companies or EPA’s engineering judgment. More information on the process used to project the high end of the r ange of expected production volumes for each company can be found below. This process is similar to the process used in the 2013 standards Notice of Proposed Rulemaking (NPRM) to calculate the expected production for each company.

We believe our range of projected production volumes for each company represents the range of what is likely to actually happen for each company. A brief description can be found below for each of the companies we believe will produce cellulosic biofuel and make it commercially available in 201 4 . We will continue to gather more information to help inform our decision regarding the cellulosic biofuel volume to be required for 201 4 in the final rule

. In the

section s that follow, we first discuss domestic cellulosic biofuel production facilities with an approved RIN generating pathway, followed by facilities with pathways that have been proposed or are currently being evaluated by EPA, and finally foreign cellulosic biofuel producers

.

EPA has determined a range of potential production volumes for each company rather than a single value as a range better reflects the uncertainty associated with the production from each company. Additionally, there are a large number of companies that EPA must assess and*** EO12866 Review

Page 20 of 111 aggregate to produce a single national volume covering the entire cellulosic biofuel industry. We believe that our projected production volume for the cellulosic biofuel industry as a whole is more accurate if it is done in such a way as to reflect the uncertainty associated w ith each of the companies that contribute to the projection. As discussed in more detail in Section II.C below, EPA is using a Monte Carlo simulation as a tool to combine our production projections for each individual company to determine a reasonable ran ge of cellulosic biofuel production in 2014 for the entire industry in a way that reflects the uncertainty across the full suite of facilities. This projected range provides a basis for public comment and helps to inform our ultimate decision on the singl e value for the final rule that best represents the projected volume of cellulosic that will

be available in 2014. Alternative methods to combine our production projections are discussed

further in Section IV.

1. Potential Domestic Producers with Appro ved Pathways

The companies and facilities discussed in this section all have the potential to produce cellulosic biofuel for use as transportation fuel, heating oil, or jet fuel in the United States in 2014. Both INEOS Bio and KiOR began producing cellul osic biofuel at commercial

- scale in 2013. The remaining seven are in various stages of construction. All seven of these facilities project the successful completion of construction of commercial scale facilities and initial fuel production in 2014. The strong financial incentive provided by the cellulosic RINs, combined with the fact that all these facilities are located in the United States and intend to use approved pathways, give us a high degree of confidence that any fuel they produce will also gene rate corresponding cellulosic biofuel RINs. 8

In order to generate RINs, each of these companies must register under the RFS program

and comply with all applicable recordkeeping and reporting requirements . This includes using an approved RIN

- generating pa thway and verifying that their feedstocks meet the definition of

renewable biomass.

Abengoa

Abengoa, a large international biofuels company, has developed an enzymatic hydrolysis technology to convert corn stover and other agricultural waste feedstocks into ethanol. After successfully testing and refining their technology at a pilot scale facility in York, Nebraska as

well as in a demonstration

- scale facil ity in Salamanca, Spain, Abengoa is now working towards the completion of their first commercial scale cellulosic ethanol facility in Hugoton, Kansas. After successfully proving their technology at commercial scale in Hugoton, Abengoa currently plans to c onstruct additional similar cellulosic ethanol production facilities, either on greenfield

sites or co

- locating these new facilities with their currently existing starch ethanol facilities

around the United States.

8 In 2012, approximately 20,000 gallons of cellulosic biofuel produced in the US was exported to Brazil to be used for promotional purposes. We believe the circumstances surrounding this export of cellulosic biofuel were unique, including significant investment in the company that produced the fuel by Petrobras, and are unlikely to be repeated by the companies included in future years.*** EO12866 Review

Page 21 of 111 Abengoa has contracts in place to provid e the majority of feedstocks necessary for the Hugoton facility for the next 10 years and successfully completed their first biomass harvest in the fall of 2011. Construction at this facility, which began in September 2011, is expected to

take approximate ly two years and be completed in the fourth quarter of 2013. All of the major process equipment for this project has been purchased and all of the required permits for construction have been approved. Abengoa’s Hugoton facility is being partially funded by a $132 million Department of Energy (DOE) loan guarantee.

When completed, the Hugoton plant will be capable of processing 700 dry tons of corn stover per day, with an expected annual ethanol production capacity of approximately 24 million gallons. Abe ngoa plans to begin producing fuel at the facility in January 2014, shortly after completing construction in late 2013

, and to be producing fuel at rates near the nameplate capacity by the end of the second quarter of 2014

. They are currently projecting 1 7

– 20 million gallons of cellulosic ethanol production from this facility in 2014. 9 This range of volumes is consistent with the 18 million gallons EPA would project if we assume production starts on January 1, 2014 and use the six

- month ramp

- up period a s a benchmark best case scenario for new cellulosic biofuel production facilities. To date construction at the Abengoa facility has proceeded as expected and EPA has no reason to believe this facility is less likely to achieve their production targets tha n any other new first

- of

- a

- kind cellulosic biofuel facility. EPA is therefore using 18 million gallons of cellulosic ethanol as the high end of the projected production range from Abengoa in todays proposed rule. For the low end of the production

range, EPA is projecting a volume of 0 gallons, consistent with our projections for all facilities that have not yet begun producing commercial volumes of cellulosic biofuel. This significantly

reduced volume reflects the fact that no commercial scale cellulosic biofuel facility has yet been able to achieve its target date for the first production of fuel. Any delay in the start

- up date of this facility would have a significant negative impact on production in 2014 and may result in production being delayed unti l 2015.

Cool Planet Biofuels

Cool Planet Biofuels has developed a process to convert a variety of forms of cellulosic biomass into a renewable gasoline product. Their process uses pressure and heat to convert the cellulosic biomass to a hydrocarbon stream in a biomass fractionator which is then upgraded using proprietary catalysts into a renewable gasoline product. Cool Planet Biofuels plans to deploy relatively small scale production units capable of producing 10 million gallons of fuel per year th at can be located near readily available sources of cellulosic biomass. In December 2012 Cool Planet Biofuels began producing fuel from their 400,000 gallon per year demonstration scale facility that is currently being used for testing purposes.

Cool Pla net Biofuels plans to begin producing fuel at their first commercial scale unit, with a nameplate capacity of 10 million gallons per year by the end of 2014. The location of this facility has not yet been announced, and it is unclear whether Cool Planet B iofuels has raised sufficient funds for the construction of this facility. Cool Planet Biofuels claims that the very

Page 22 of 111 short construction time they anticipate for their facility relative to cellulosic biofuel production facilities of similar size, which gen erally take at least two years to build, is made possible by their use of very little novel equipment. The majority of the facility is composed of units already used in commercial operation in other applications that will be purchased from vendors and

ass embled by Cool Planet Biofuels. The facility will be constructed on cargo container skids and then transported to the fuel production site.

EPA believes that it may be possible for Cool Planet Biofuels to produce cellulosic

biofuel from their first com mercial scale production facility in 2014, but any production from this facility is highly uncertain. Historically the construction of cellulosic biofuel production facilities has taken multiple years, with delays to the initial construction schedules com mon. Cool Planet’s unique construction plan may allow for a reduced construction timeframe; however we do not believe it would be appropriate to rely on this in projecting available volumes

of cellulosic biofuel in 2014. We have therefore not included an y volume from Cool Planet Biofuels in our projection of the potentially available volume of cellulosic biofuel in 2014 in today’s proposal.

DuPont

DuPont has developed an enzymatic process to convert corn stover into cellulosic

ethanol. DuPont has inves ted hundreds of millions of dollars to develop this technology and since 2009 has operated a small demonstration scale facility in Vonore, Tennessee. In addition to developing technology for converting cellulosic biomass to ethanol, DuPont has been workin g with corn producers, equipment manufacturers, and Iowa State University to develop expertise in the collection, transportation, and storage of the biomass feedstock for their cellulosic ethanol facilities. On March 29, 2013 DuPont signed an agreement wi th USDA to promote the sustainable harvesting of feedstocks for cellulosic biofuel facilities.

On November 30, 2012 DuPont began the construction of their first commercial scale cellulosic ethanol facility in Nevada, Iowa. When completed, this facility will have a nameplate production capacity of 30 million gallons of cellulosic ethanol per year. DuPont currently plans to achieve mechanical completion at this facility in June 2014 and to begin production in the second half of 2014. They are currently projecting the production of approximately 3 million gallons of cellulosic ethanol from this facility in 2014; however they acknowledge that even slight delays in their expected construction timeline could have significant impacts on their fuel production in 2014. Using EPA’s best

- case benchmark of a six month straight

- line ramp

- up period assuming a production startup date of October 1, 2014 would result in an expected production of approximately 2 million gallons in 2014. Due to the start

- up date that is late in the year, however, even a relatively minor delay in the construction and commissioning timeline or unforeseen challenges in start

- up would result in no production from this facility in 2014. We have projected a range or 0

– 2 million gallons of c ellulosic biofuel from DuPont’s Nevada, Iowa facility in 2014.

Page 23 of 111 Fiberight uses an enzymatic hydrolysis process to convert the biogenic portion of separated municipal solid waste ( MSW ) and other waste feedstocks into ethanol. They have

successfu lly completed five years of development work on their technology at their small pilot plant in Lawrenceville, Virginia. In 2009 Fiberight purchased an idled corn ethanol plant in Blairstown, Iowa with the intention of making modifications to this facility to allow for the production of 6 million gallons of cellulosic ethanol per year from separated MSW and industrial waste streams. These modifications were scheduled to be completed in 2011, but difficulties in securing funding have resulted in constructio n at this facility being delayed. In January 2012 Fiberight was offered a $25 million loan guarantee from USDA. Closing on this loan would provide substantially all of the remaining funds required for Fiberight to complete the required

modifications at t

heir Blairstown facility. Additional c onstruction will be required at this facility before the production of cellulosic biofuel can begin, and the company expects that this

construction will take approximately 6 months to complete. Additionally, Fiberigh t ’s waste separation plan for this facility was approved in June 2012 allowing Fibe right to generate RINs

for the cellulosic ethanol they produce using separated MSW as a feedstock. Because of the uncertainty surrounding Fibright’s funding status, the lac k of progress towards the completion of the modifications at their Blairstown, Iowa facility, and their history of production delays EPA is not including any volume from Fiberight in today’s proposal.

INEOS Bio

INEOS Bio has developed a process for producing cellulosic ethanol by first gasifying

cellulosic feedstocks into a synthesis gas ( syngas ) and then using naturally occurring bacteria to ferment the syngas into ethanol. In January 2011

, USDA announced a $75 million loan guarantee for the construction of INEOS Bio’s first commercial facility to be built in Vero Beach, Florida. This loan was closed in August 2011. This was in addition to the grant of up to
$50 million INEOS Bio received from DOE in December 2009. At full capacity , this facility will be capable of producing 8 million gallons of cellulosic biofuel as well as 6 megawatts (gross) of renewable electricity from a variety of feedstocks including food and yard waste

, agricultural residues

, slash and pre

- commercial thinnings, and tree residues from tree plantations. 10 The facility also plans to use a limited quantity of separated MSW as a feedstock

after initial start

- up

.

On February 9, 2011, INEOS Bio broke ground on this facility. INEOS Bio complete d construction on this facility in June 2012 and began full commissioning of the facility

. In August 2012 INEOS Bio received approval from EPA for their yard waste separation plan and successfully registered their Vero Beach, FL facility under the RFS program. In October 2012 the facility began producing renewable electricity. INEOS Bio entered the start

- up phase of

cellulosic ethanol production in November 2012. During this phase the facility was not run continually, as facility modifications c ontinued to be made; however, a small volume of cellulosic ethanol was successfully produced. On July 31, 2013, INEOS Bio announced they had begun producing cellulosic ethanol at commercial scale from their Vero Beach facility. INEOS Bio currently projec ts cellulosic ethanol production at this facility to be 4

- 5 million gallons in

10 Both slash and pre

- commercial thinnings and tree residue from tree plantations must come from non

- federal forestland to qualify as a feedstock in the RFS program. Additionally slash and pre

- commercial thin nings must come from land that is not ecologically sensitive forest land.*** EO12866 Review

Page 24 of 111 2013

. As this volume is less than what would be projected using our best

- case ramp

- up benchmark we believe it is an appropriate volume to represent the upper end of INEOS Bio’s potential production range for 2014.

There is, however, significant uncertainty in the ability of this facility to achieve these production volumes in 2014. The facility has not yet reached production rates consistent with its projected production vol

ume, and production ramp

- up could take longer than expected. INEOS Bio also experienced several setbacks to production related to weather

- caused power losses at the facility. While they are working to protect against these issues in the future by enablin g the facility to operate in a self

- sustaining mode, the possibility of future interruption due to serious weather events will still exist. For this proposed rule we are projecting a production range of 2

– 5 million gallons of cellulosic ethanol from INE OS Bio’s Vero Beach facility in 2014. The low end of the range accounts for the possibility of both an extended ramp

- up period and interruptions to production continuing into 2014.

KiOR

KiOR is working to commercialize a technology capable of converting biomass to a biocrude using a process they call Biomass Fluid Catalytic Cracking (BFCC). BFCC uses a catalyst developed by KiOR in a process similar to Fluid Catalytic Cracking currently used in the petroleum industry. The first stage of this process pr oduces a renewable crude oil which is then upgraded to produce primarily gasoline, diesel, and jet fuel as well as a small quantity of fuel oil, all of which are nearly identical to those produced from petroleum.

KiOR’s first commercial scale facility i s located in Columbus, Mississippi and is capable of producing approximately 11 million gallons of gasoline, diesel, and jet fuel per year. Construction on this facility began in May 2011 and was completed in September 2012 . This facility is funded, in l arge part, with funds acquired through private equity raises and supplemented by KiOR’s $150 million IPO in June 2011. On March 17, 2013 KiOR generated their first cellulosic biofuel RINs from this facility. KiOR initially announced that they expected

th e start

- up period at their Columbus facility to last 9

- 12 months, during which time they estimate fuel production will average 30%

- 50% of the facility capacity and production rates at or near nameplate capacity following. On August 8, 2013 KiOR reduced it s production targets for

2013 from 3

- 5 million gallons to 1

- 2 million gallons. KiOR has feedstock supply agreements in place to supply all of the required feedstock for their Columbus facility with slash and pre

commercial thinning. They also have of f

- take agreements with several companies for all of the fuel that will be produced.

In today’s proposal we are projecting a production range of 0

– 9 million ethanol

equivalent gallons in 2014 from KiOR’s Columbus, MS facility. The high end of our prop osed production projection (5.5 million actual gallons or 9 million ethanol

- equivalent gallons) has been calculated assuming this facility produces at an average rate of 50% of nameplate capacity throughout 2014. We believe this reduced volume is appropri ate given the low production volumes KiOR has achieved to date and KiOR's statements, in an August 8, 2013 conference call discussing their second quarter performance, that they had not yet begun focusing on increasing*** EO12866 Review

Page 25 of 111 the efficiency and yields of the faci lity. The low end of the range (0 million gallons) reflects uncertainty surrounding KiOR’s future production levels.

LanzaTech

LanzaTech has developed a process for the production of ethanol from feedstock streams

that contain carbon monoxide. The Lanz aTech process can utilize industrial waste gas streams or syngas produced from the gasification of agricultural residues, woody biomass, or other

cellulosic feedstocks. 11 These gas streams are dispersed into a liquid medium where they are converted into ethanol or other chemicals by LanzaTech’s proprietary microbes. LanzaTech is currently using this technology at two demonstration scale facilities in China, producing eth anol from waste gasses at steel mills in partnership with Baosteel and Capital Steel.

On January 3, 2012 LanzaTech purchased the former Range Fuels facility in Soperton, Georgia. LanzaTech is currently in the process of assessing the equipment in place a t this facility. After making any necessary modifications to the existing gasifiers they plan to install units to allow for the production of ethanol from syngas produced from the gasification of local woody biomass. LanzaTech believes the current produc tion capacity of the gasifiers when used in combination with their ethanol producing microbes is approximately 4

– 6 million gallons per year, with the potential for further expansion to allow for the production of 20

– 30 million gallons per year at this site. At this point, however, LanzaTech is not projecting initial ethanol production from this facility until late 2014 or early 2015. EPA has therefore not included any volume from LanzaTech in our cellulosic biofuel projections in this proposed rule.

Poet

Poet has developed an enzymatic hydrolysis process to convert cellulosic biomass into ethanol. Poet has been investing in the development of cellulosic ethanol technology for more than a decade and began producing small volumes of cellulosic ethanol at pilot scale at their plant in Scotland, South Dakota in late 2008. In January 2012, Poet formed a joint venture with Royal DSM of the Netherlands

, called Poet

- DSM Advanced Biofuels

, to commercialize and license their cellulosic ethanol technology.

The joint venture’s first commercial scale facility, called Project LIBERTY, will be located in Emmetsburg, Iowa. This facility is designed to process 770 dry tons of corn cobs, leaves, husks, and some stalk per day into cellulosic ethanol. The facility is projected to have an annual production of approximately 25 million gallons per year. In anticipation of the start

- up of this facility, Poet constructed a 22

- acre biomass storage facility and had its first commercial harvest in 2010, collecting 56,000 tons of biomass.

Site prep work for Project LIBERTY began in the summer of 2011, and vertical construction of the facility began in the spring of 2012. Poet was awarded a $105 million loan

11 RIN generation would be limited to fuels produced using approved sources of biomass such as agricultural residue, tree residue from a tree plantation, or slash and pre

- commercial t hinnings. LanzaTech would be required to meet all recordkeeping and reporting requirements to demonstrate the feedstock is renewable biomass sourced from land that meets all of the land use requirements of the RFS program.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 26 of 111 guarantee offer for this project from DOE in July 2011, but with the joint venture it decided to proceed without the loan guarantee. This project is expected to be completed in the first half of 2014 and will be followed by a commissioning period before t he plant begins cellulosic ethanol production

. Poet currently projects that production from Project LIBERTY will be between 7 and 12 million gallons of cellulosic ethanol in 2014. Using the six month best

- case ramp

- up period with production beginning on July 1, 2014 would result in a volume projection of 6 million gallons from this facility. In today’s proposed rule, EPA is therefore setting the high end of Poet’s projected production range at 6 million gallons of cellulosic ethanol. The low end of

the projected production range for Poet’s Project LIBERTY is 0 gallons in 2014. This number reflects the fact that any significant delay in the start

- up date or difficulties encountered in the commissioning or start

- up phases of production are likely to resul t in little to no production from this facility in 2014. While EPA has no reason to believe this facility will be any more prone to these types of challenges than any other commercial scale cellulosic biofuel production facility, our experience suggests t hat these types of delays are common and should be considered when projecting the low end of the range for production volume in 2014.

Sweetwater Energy

Sweetwater Energy has also developed a technology for converting cellulosic biomass, primarily agricul tural residues and woody biomass, to cellulosic sugars. Sweetwater Energy uses a modular approach, building relatively small facilities near the source of feedstock and transporting the sugars they produce to a larger facility to be converted into renewab le fuels or chemicals. They currently have two arrangements in place with corn ethanol facilities in the United States to provide cellulosic sugars in sufficient quantity for the production of 3.6 million gallons of cellulosic ethanol from each of these f acilities. Both of Sweetwater Energy’s cellulosic sugar production modules are scheduled to begin production in the summer of 2014. If both these facilities begin producing sugars that are converted to cellulosic biofuel on July 1, 2014, our best case sc enario benchmark six month straight

- line ramp

- up period would project a

volume of 2 million ethanol

- equivalent gallons. At this time, however, cellulosic RINs would not be able to be generated for any fuel produced using Sweetwater Energy’s cellulosic sug ars since the existing RFS registration regulations were not designed to allow the subdivision of processes between multiple facilities. Until this is resolved, fuel production processes of this type will not be able to generate RINs. We therefore have n ot included any volume from Sweetwater Energy in our projections of cellulosic biofuel for 2014.

Ensyn

Ensyn has developed a technology called Rapid Thermal Processing (RTP) that uses heat to thermally crack carbon based feedstocks into a liquid bio

- oil product they call renewable fuel oil (RFO). This conversion takes place in less than two seconds and is similar to the fluid catalytic cracking (FCC) process used in many refineries. Ensyn is currently using this technology in two commercial facilities l ocated in Wisconsin and Ontario, Canada to produce renewable chemicals, food additives, and heating oil. They estimate that they have up to 3 million gallons of additional capacity at these two facilities that could be utilized if the fuel were eligible t o generate RINs under the RFS program as home heating oil. This facility has a history of consistent production and we therefore believe this projection of 3 mill gal, or 5 million*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 27 of 111 ethanol

- equivalent gallons, is an appropriate number to use as the high en d of the projected

range.

Until recently the RFS regulations required that to qualify as “heating oil” for which RINs may be generated the fuel must be #1 diesel fuel, #2 diesel fuel, or any non

- petroleum diesel blend that is sold for use in furnaces, boi lers, and similar applications and which is commonly or commercially known or sold as heating oil, fuel oil, and similar trade names, and that is not jet fuel, kerosene, or motor vehicle, nonroad, locomotive or marine diesel fuel (MVNRLM). On September 24 th , 2013, EPA finalized a rule to amend this definition to include

any:

fuel oil that, pursuant to §80.1450(b)(1)(ix) and (d)(4), 80.1451(b)(1)(ii)(T), 80.1453(d) and 80.1454(b)(7), is demonstrated to be used to heat interior spaces of homes or buildings to control ambient climate for human comfort, is capable of flowing at 60 degrees Fahrenheit and 1 atmosphere of pressure, and is not used for any other purpose. 12

This amendment allows the RFO produced by Ensyn to qualify for RINs if it were used

to heat buildings where people live, work, recreate, or conduct other activities and it meets the other required components of the proposed definition. However, even if the fuel produced using the RTP process meets the new definition, Ensyn still faces sever al challenges to generating cellulosic biofuel RINs. Ensyn must still secure approved sources of renewable feedstock for their existing production facilities, increase production at these facilities, and find customers willing to make the modifications ne cessary to use Ensyn’s RFO as home heating oil. Any of these steps could result in delays in the increased production or qualifying use of RFO until 2015. For this proposal EPA is projecting a range of production of 0

– 3 million gallons (0

– 5

million e thanol

- equivalent gallons) from Ensyn’s facilities in 2014. This volume has not been included in EPA’s primary projection of cellulosic biofuel projection for 2014 due to the outstanding issues mentioned above, but has been considered in our projection of all potentially available cellulosic biofuel, including companies without existing pathways for generating cellulosic biofuel RINs. In light of the recent amendments to the home heating oil definition, EPA will review this projection and make adjustments as necessary in the final rule.

2. Potential Domestic Producers without Existing Pathways

In addition to the facilities discussed above, there are a number of companies with the potential to produce cellulosic biofuel from domestic facilities in 2014 from pathways that have not been approved for RIN generation by EPA. Some of these pathways were addressed in a notice of proposed rulemaking published by EPA on June 14, 2013, while others are currently being evaluated by EPA. As the companies discusse d in this section do not yet have approved RIN generating pathways for the fuels they plan to produce, there is additional uncertainty regarding RIN production from them in 2014. 13 Nevertheless, if the pathways are approved by

12 77 FR 61313 (October 9, 2012)

. 13 At the time of this proposal, EPA has finalized changes to the home heating oil definition but has not yet completed our determination of whether or not the fuels discussed in this section meet all of the requirements to generate cellulosic biofuel RIN s.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 28 of 111 EPA these facilities represen t a significant potential source of cellulosic biofuel. The ranges projected for each company reflect only the uncertainty associated with production volumes, assuming pathway approval occurs. 14 EPA will decide whether or not to include any volume

from th ese pathways based on the status of these pathways and the progress made by the companies towards commercial cellulosic biofuel production at the time of the final rule.

Compressed Natural Gas (CNG) and Liquified Natural Gas (LNG) Producers

One of the n ew pathways proposed by EPA for the production of cellulosic biofuel is for the production of CNG or LNG from landfill biogas if used as a transportation fuel. The production potential for this type of cellulosic biofuel is very large with many landfills currently capturing biogas. The use of CNG and LNG as a transportation fuel in 2014 is expected to be approximately 700 million ethanol

- equivalent gallons. 15 To generate RINs for landfill biogas, however, companies must be able to demonstrate that any fue l for which they generate RINs is used as transportation fuel. This can be done by fueling vehicles with CNG/LNG onsite or through contractual mechanisms.

In this proposed rule, we are projecting a production range of 35

- 54 million ethanol

equivalent gallons from landfill biogas in 2014. The high end of the range represents the actual peak capacity of all of the facilities that produced advanced RINs from landfill biogas while the low end represents the current production rate of advanced biofuel from landfill biogas. In the case of CNG and LNG from landfill biogas, we believe a different methodology for projecting the high end of the production range is appropriate as the uncertainties surrounding RIN generation are significantly different. The only change at issue in the proposal to approve this pathway for the generation of cellulosic biofuel RINs is a change in the type of RIN that is generated, allowing for the generation of cellulosic biofuel instead of advanced biofuel RINs

based on new informa tion of the composition of the feedstock. In this case production facilities already exist and are already capturing landfill biogas at or near their registered capacities. Similarly, the amount of CNG and LNG currently being used as transportation fuel far exceeds the combined production capacity of all of the registered facilities. RIN generation is therefore limited by the companies’ ability to demonstrate the use of the biogas as a transportation fuel. 16
As part of the registration process for the ge neration of advanced biofuel RINs, each of these facilities submitted documentation that included contracts with parties capable of using CNG/LNG as transportation fuel who had access to the same common carrier pipeline network as the biofuel producers.

We believe the sum of the actual peak capacities of all of the facilities that produced advanced biofuel RINs from landfill biogas in 2013 is an appropriate volume to use for the high end of the projected production range. It is also the case, however, t hat these facilities would appear to have the capability to realize value from advanced RIN production if they were to produce at their facility capacity and are not currently doing so. There may be additional factors

that EPA is unaware of at this time t hat is limiting production. To account for this, we are

14 In projecting potential production volumes EPA has assumed that the pathways are all approved as of January 1, 2014. Approval subsequent to that date would reduce potential volumes, depending on the producer at issue.

Edeniq

Edeniq has developed a proprietary process that would allow corn ethanol producers to generate cellulosic ethanol from corn kernel fiber at the producers’ existing production facilities. Their process involves the addition of the CellunatorTM, a p roprietary milling technology designed to increase the uniformity of the feedstock particles, along with a unique combination of enzymes to convert the cellulosic material in the corn kernel into sugars and ultimately cellulosic ethanol. Edeniq claims tha t their technology would not only allow corn ethanol producers to produce cellulosic ethanol from low value feedstock already present in their facility, but also would increase the yields of ethanol produced from starch by 2

- 4%. Several commercial plants are currently using the Cellunator technology to increase their yields of ethanol from starch. Edeniq has been testing their technology, including both the Cellunator and the additional enzymes, at a demonstration scale facility in Visalia, California sin ce June 2012 and announced in May 2013 that they had successfully completed a trial run at this facility with a continuous run time of greater than 1000 hours.

Several plants are evaluating Edeniq’s proprietary system to produce cellulosic ethanol

from c orn kernel fiber. These evaluations have included commercial scale trials. If the pathway for the production of cellulosic ethanol from corn kernel fiber is approved, these facilities would be in position to begin generating cellulosic RINs shortly after approval. Other facilities currently using the Cellunator would only have to make minor modifications to their operations, including the addition of Edeniq’s suite of enzymes to produce cellulosic ethanol. Edeniq currently projects approximately 7 milli on gallons of cellulosic ethanol production using their technology in 2014 and has provided EPA with detailed information on the expected production volumes and dates of initial cellulosic ethanol production for facilities expected to utilize their

technol ogy. In today’s proposed rule, we have included a projected production volume of 0

– 7 million gallons. The low end of this range reflects the fact that Edeniq’s technology has not yet been used to generate commercial scale volumes of cellulosic biofuel. The high end of the range reflects Edeniq’s own projections, which EPA has reviewed and believes are reasonable given the nature of Edeniq’s technology, the deals they currently have in place, and their experience with the installation and operation of t he various components of their technology. This volume is also dependent on the finalization of EPA’s proposed rule clarifying that the definition of crop

residue includes corn kernel fiber.

3. Potential Foreign Sources of Cellulosic Biofuel

In addi tion to the potential sources of cellulosic biofuel located in the United States discussed above there are several foreign cellulosic biofuel companies that may produce cellulosic biofuel in 2014. All of these facilities utilize fuel production pathways t hat have been approved by EPA for cellulosic RIN generation provided eligible sources of renewable feedstock are used. These companies would therefore be eligible to register these facilities under the RFS*** EO12866 Review

Page 30 of 111 program and generate RINs for any fuel imported i nto the United States. Currently, however,

none of these facilities have successfully completed the registration process for the RFS

program

. Further, demand for the cellulosic biofuels they produce is expected to be high in local markets. Production volumes from these foreign facilities have therefore not been included in our projection of potentially available volume for 2014. EPA plans to c ontinue to monitor the progress of these foreign facilities and may include volumes from these facilities should their plans change in the future.

Beta Renewables

Beta Renewables has developed a biochemical technology to convert cellulosic biomass

into cellulosic sugars, which can then be used in the production of fuels or chemicals. Their first commercial scale facility was built in Crescentino, Italy and began producing cellulosic ethanol in commercial quantities in June 2013. This facility uses Arun do donax and wheat straw as feedstocks and has an annual production capacity of 20 million gallons of ethanol per year. Ethanol produced at this facility would be eligible to generate cellulosic RINs if Beta Renewables registers its facility and imports t he cellulosic ethanol into the United States for use as a transportation fuel. Beta Renewables is also planning to build a cellulosic ethanol production facility in North Carolina. This facility is not expected to begin ethanol production in 2014, howeve r, and has therefore not been included in our projection of available volume for

2014.

Enerkem

Enerkem plans to use a thermochemical process to produce syngas from MSW and other

waste materials and then catalytically convert the syngas to methanol. The methanol can then be sold directly or upgraded to ethanol or other chemical products. Their first commercial scale facility in Edmonton, Alberta, Canada is scheduled to complete construction and begin producing methanol in 2013 with ethanol production fo llowing in 2014. At full capacity this facility will be capable of producing 10 million gallons of cellulosic ethanol per year. Despite their relative close proximity to the United States, Enerkem has indicated to EPA that they do not

intend to export ce llulosic biofuel into the United States from their Edmonton facility

.

GranBio

GranBio began construction on its first commercial cellulosic ethanol production facility in São Miguel dos Campos, Brazil in December 2012. It is largely funded by a 300.3 million Reais loan from BNDES, Brazil’s national social and economic development bank. This facility, which will use technology licensed from Beta Renewables, will have a nameplate capacity of 22 million gallons of ethanol per year and is scheduled to be completed in the first half of 2014. The feedstock for this facility will be excess bagasse not currently used to provide process heat or electricity at sugarcane ethanol production facilities.

Raizen*** EO12866 Review

Page 31 of 111 Raizen, a joint venture between Royal Dutch Shell and Cosan SA, is planning to build a 10.5 million gallon per year cellulosic ethanol plant attached to their Costa Pinto sugarcane mill in Piracicaba, Brazil. This facility will use a biochemical conversion technology developed by Iogen and Codexis to con vert sugarcane bagasse to ethanol. The facility is currently scheduled to complete construction in the second half of 2014 and if successful will be the first of up to 8 cellulosic ethanol production facilities built by Raizen in Brazil.

. Summary of Volume Projections for Individual Companies

The i nformation we have gathered on cellulosic biofuel producers, described above, allows us to project a range of production volumes for each facility in 201 4

. As in 2013, we have once again focused on commerc ial scale cellulosic biofuel production facilities. This focus is appropriate, as the volume of cellulosic biofuel produced from R&D and pilot scale facilities is quite small in relation to that expected from the commercial scale facilities for which we h ave projected volumes in 2014 and historically R&D and demonstration scale facilities have not generated RINs for any fuel they have produced.

In 201 4 as many as twelve domestic cellulosic biofuel production facilities have the potential to produce fuel a t commercial scale . Each of these facilities is discussed above, and the projected available volumes for each are summarized in Table II. B

. 4

- 1 below. Two of the companies that have the potential to produce cellulosic biofuel in 2014, INEOS Bio and KiOR, are currently producing cellulosic biofuel. The production of RIN generating fuel from the remaining 10 facilities is more uncertain as these facilities have either yet to complete construction or do not currently have a valid pathway for generating cellu losic RINs.

We have also identified four foreign facilities with the potential to produce cellulosic ethanol in 2014. At this point we do not believe any of these facilities are likely to export any of

th e fuel they produce to the United States. We will continue to monitor the status of these facilities and may include volume from them in our final rule if appropriate. We ask for comment on this analysis and are especially interested in data that would s upport cellulosic

volume estimates.

. Proposed Cellulosic Biofuel Volume for 201 4

As discussed in the preceding sections we have used information from a variety of sources, including EIA, USDA, and the companies th emselves, to determine a projected range of production of cellulosic biofuel for each company in 2014. These volumes are summarized in

Table II.B.4

- 1 above. These volumes form the basis for our projection of cellulosic biofuel production in 2014. We do not believe, however, that a simple summation of the low end and high end of the projected production volumes for each company would result in an appropriate projected range of production volumes across the cellulosic biofuel industry. It is highly

unlike ly that every company will produce at or near the low end, or conversely the high end, of its range of projected production volumes. It is also the case that the production expectations within the projected ranges differ for facilities in different stages . The uncertainties associated with cellulosic biofuel production vary in both type and degree among facilities that have already begun production, those that are currently in or will soon be approaching the commissioning of their facilities, and those th at are still undergoing significant construction operations.

EPA is using a Monte Carlo simulation to account for the need to aggregate across several ranges, with different producers having different production probability distributions

across their expected production range. As discussed above, the high and the low end of each range represents values such that it is possible but highly unlikely that volumes would be higher or lower than this range. EPA will therefore treat these individual ranges a s representing the 90% confidence interval of a distribution of possible volumes. In other words, the low end of the range for a producer would represent the 5th percentile and the high end of the range would represent the 95th percentile. This approach is consistent with EPA’s judgment that, while the ranges shown in Table II.B.4

- 1 are intended to encompass the vast majority of possible volumes, there remains a small possibility that volumes outside of those ranges are possible. We believe it

is reasona ble to treat these values as a 90% confidence interval for purposes of the Monte Carlo analysis, though we request comment on treating them as a different confidence interval such as

80% or 95%.

For the purposes of the Monte Carlo analysis, EPA must also identify an uncertainty distribution for production for each facility. These distributions reflect our expectation for the most likely distribution of production volumes within the projected range when taking into account the many different uncertainties associated with the production volume from each facility. While each facility faces its own set of unique circumstances and challenges in producing cellulosic biofuels at commercial scale, many can be grouped into one of several general categories, the im pact of which will vary with the progress achieved at that facility to date. One source of uncertainty in the projected production volume of a new cellulosic biofuel facility is related to the completion of the construction and commissioning phases of the facility. This includes uncertainty in the construction schedules, modifications to the design during the construction or commissioning phase, challenges encountered in scaling up the technology to commercial scale, unexpected delays or repairs due to we ather events, or any of a number of other reasons. Delays of this type will result in a later than expected start

- up date which may result in significantly decreased production volumes in 2014 or the start of production being delayed until 2015. The unce rtainty related to delays in the completion of the construction of a*** EO12866 Review

Page 35 of 111 facility decreases the closer the project is to completion, and is entirely irrelevant to facilities that have already begun production.

A second source of uncertainty is that associated with the ramp

- up phase of new facilities. Lower than expected product yields, feedstock supply and handling challenges, contamination of chemical or biological catalysts, and a number of other issues can cause reduced production during the ramp

- up phase and/or a longer than expected ramp

- up period before reaching production levels that correspond to the nameplate capacity of the facility. Facilities that face these types of challenges during the ramp

- up phase of production are very likely to still achiev e some level of production, but that level may vary depending on the severity and duration of the challenges they face. The closer a facility is to achieving production rates that correspond to the nameplate capacity of the facility, the less likely they are to see reductions in their expected production due to challenges in the ramp

- up phase.

A third source of uncertainty is the ability of the facility to maintain consistent production at or near nameplate capacity after the ramp

- up phase has been succes sfully completed. A number of factors including, but not limited to feedstock supply interruption, significant issues with feedstock quality, loss of power or other essential utilities at the facility, and interruptions in production due to accidents, ope rator error, or weather events could cause fuel production at a facility to decrease or cease altogether. While the uncertainty associated with these issues is never completely absent, it does decrease over time if a facility is able to consistently achie ve production levels at or near nameplate capacity with few or no interruptions to production.

The degree to which these three sources of uncertainty impact expected production of cellulosic biofuel in 2014 varies greatly with the progress achieved by the facility to date. To represent this uncertainty for facilities expected to begin operations in different timeframes, we used three different standardized uncertainty distributions. The three standard curves that represent the expected production distrib utions from cellulosic biofuel production facilities are shown in Figure II.C

- 1 below. We request comment on how well these three curves represent the expected production distributions of the various cellulosic biofuel producers discussed above

or if othe r curves may be more appropriate.*** EO12866 Review

- 1 Standardized Distributions Used to Project Aggregate Cellulosic Biofuel Production a

a The skewed distribution is based on a Weibull distribution with a shape parameter of 0.5 and a scale parameter of 1.7

.

As described more fully in Section IV.B.4, we believe that these three standardized distributions provide a mechanism for representing the regions within each projected volume range where the greatest likelihood of reasonably achievable volumes lie.

Facil ities that have already begun producing cellulosic biofuel in 2012 or earlier and have at least a full year of production history do not face uncertainty associated with delays in the construction and commissioning of the facility. They may, however, face some uncertainty in their ramp

- up schedule relative to the progress they have achieved to date, as well as the risk of unexpected shutdown or slowdown faced by all facilities. For facilities facing these uncertainties we expect that the most likely produ ction volume is towards the middle of the range, with decreasing production probabilities as the high and low ends of the production ranges are approached. A normal curve is appropriate for this expected production distribution. In 2014, however, there a

re no commercial scale cellulosic biofuel production facilities that meet these

criteria.

Facilities that began producing cellulosic biofuel in 2013 no longer face uncertainty due to potential delays in the completion of construction and the commissioning of the facility. There is, however, uncertainty regarding these facilities ramp

- up schedules which can have a significant impact on the production volumes from these facilities. We believe that the expected production of these facilities would be best r epresented by a right

- skewed or Weibull curve, with the most likely production volume near, but not at, the low end of the range and the production probabilities gradually towards the high end of the range.

Facilities not expected to begin producing cellu losic biofuel until 2014 face uncertainty associated with a delay in the completion in the construction and commissioning of the facility. Given this uncertainty, we believe that the most likely production volume is at the low end of the*** EO12866 Review

- normal curve is a reasonable representation of the expected production distribution from these facilities.

To aggregate the production distributions for each of the companies into a single distribution representing cellulosic biofuel production across the entire industry, we performed two Monte Carlo simulations in which each of the distributions was randomly s ampled in an iterative fashion. Each of the distributions was sampled 3000 times and the results of all the iterations were then summed to produce a distribution for cellulosic biofuel. For the uncertainty distributions where the low end of the projected range was zero it was possible for the Monte Carlo simulation to select a negative volume for these companies. 17 Whenever negative volumes were selected in the Monte Carlo simulations these negative volumes were reset to zero.

We generated two separate aggregate distributions to represent total cellulosic biofuel using the Monte Carlo process. Given the uncertainty surrounding the timing and approval of the proposed RIN

- generating pathways that would be used by CNG/LNG producers, Edeniq, and Ensyn, the first aggregate distribution only included volumes from those facilities using RIN

generating pathways that have already been approved. The result of this Monte Carlo simulation forms the basis for the range of cellulosic biofuel production included in t his proposal.

17 Because the low end of each range represents the 5 th percentile, negative volumes are selected approximately 5%

of th e time when the low end of the range is zero.*** EO12866 Review

Results of Monte Carlo Simulation for Cellulosic Biofuel Production

(All Potential Cellulosic Biofuel Producers)

In today’s NPRM we are proposing a volume for the 201 4 cellulosic biofuel standard of 8

- 30 million ethanol

- equivalent gallons. This volume is expected to be comprised of 5

- 26 million gallons of ethanol and 0

- 9 milli on ethanol

- equivalent gallons of cellulosic hydrocarbons. 18 The proposed range is derived from the 90% confidence interval of the Monte Carlo simulation that includes all the companies we expect to produce commercial volumes of

cellulosic biofuel in 2014 u sing pathways in the current RFS regulations. As discussed in Section II.B, m any factors have been taken into consideration in developing the individual

company projections , such as the information from EIA, the current status of project funding, the

stat us of the production facility, anticipated construction timelines, the anticipated start

- up date and ramp

- up schedule, feedstock supply

, and many others. We have also used distribution curves weighted towards the low end of the expected production range f or each company to account for the fact that previous projections of cellulosic biofuel production have exceeded actual production. We believe the range of volumes proposed ( 8

- 30 million ethanol

- equivalent gallons) resulting from the Monte Carlo simulat ion is a reasonable representation of expected production in 2014 across the industry

.

Our proposed range reflects EPA’s best estimate of the range of cellulosic biofuel volumes that will actually be produced in 2014. In the final rule EPA will determi ne a single volume that represents EPA’s best estimate of the volume that will actually be produced in

18 These volumes are also the result of our Monte Carlo simulation. Similar to the individual company production projections, the low and high ends of the ranges cannot be simply added together to calculate t he high and low ends of our total cellulosic biofuel production projection in 2014. Cellulosic hydrocarbons include both cellulosic gasoline and cellulosic diesel.*** EO12866 Review

For example, EPA could use the mean (average value), median (50 th percentile), or mode (the volume that occurs most frequently). It may also be reasonable to use a value representing higher or lower values in the distribution, such as the

25 th or 75 th percentile if there is reason to believe these would provide a more accurate projection of actual production in 2014. 20 We have determined the volumes represented by each of these methods and presented the values in Tables II.C

In today's NPRM, we are proposing to use the mean value for the final volume requirement for cellulosic because we believe it best represents a neutral aim at the volumes that could reasonably be supplied. However, we request comment on whether one of the alternative values

shown in Table II.C

cellulosic biofuel in the final rule.

It is important to note that the final cellulosic biofuel standard fo r 201 4 may be set at a

volume outside the proposed range of 8

- 30 million ethanol

- equivalent gallons

. If EPA finalizes the pathways discussed in the recent proposed rulemaking 21 before the applicable volume of cellulosic biofuel for 2014 is finalized, vol umes of fuel from companies intending to utilize these pathways may be included in our projected available volume for 2014 as discussed above.

20 This could be the case if there was re ason to believe there was a systematic bias such that the ranges tended to over or under estimate the actual production volumes.

sources other than those listed above.

We will continue to monitor the progress of the cellulosic biofuel industry, in particular the progress of the companies which form the basis of our proposed 201 4 volume projection.

W e expect that for the final rule there will be greater certainty on the appropriate volume of fuel that we can reasonably expect to be produced and made commercially available in 201 4

D. Rescission of the 2011 Cellulosic B iofuel Standards

On January 25, 2013, t

he United States Court of Appeals for the District of Columbia

Circuit issued its decision concerning a challenge to the 2012 cellulosic biofuel standard

. The Court found that in establishing the applicable volume o f cellulosic biofuel for 2012, EPA had used a methodology in which “the risk of overestimation [was] set deliberately to outweigh the

risk of underestimation.” The Court held EPA’s action to be inconsistent with the statute because EPA had failed to apply a “neutral methodology” aimed at providing a prediction of “what will actually happen,” as required by the statute. As a result of this ruling, the Court vacated the 2012 cellulosic biofuel standard, and we removed the 2012 requirement from the regulatio ns in a previous action. Industry had also challenged the 2011 cellulosic biofuel standard by, first, filing a petition for reconsideration of that standard, and then seeking judicial review of our denial of the petition for reconsideration. This matter was still pending at the time of the D.C. Circuit’s ruling on the 2012 cellulosic biofuel standard. Since we used essentially the same methodology to develop the 2011 cellulosic biofuel standard as we did to develop the 2012 standard, we requested, and th e Court granted, a partial voluntary remand to enable us to reconsider our denial of the petition for reconsideration of the 2011 cellulosic biofuel standard. Given the Court's ruling that the methodology EPA used in developing the 2012 cellulosic

biofuel standard was flawed, we have decided to grant reconsideration of the 2011 cellulosic biofuel standard, and are today proposing to rescind the 2011 cellulosic biofuel standard. If this proposal is finalized, the money paid by obligated parties to purchase cellulosic waiver credits to comply with the 2011 cellulosic biofuel standard would be refunded.

22 Since EPA is proposing to reduce the applicable volume of cellulosic biofuel under section 211 (o)(7)(D), EPA will be required to make available cellulosic biofuel credits. EPA will set the price for the cellulosic biofuel credits in the final rule, using the same approach to applying the criteria in section 211(o)(7)(D)(ii) that was used in settin g the price for cellulosic biofuel credits for 2013.

Page 42 of 111 I I I. Proposed National Volume Requirement for Biomass

- Based Diesel in 201 4 and 2015

EPA set the national volume requirement for biomass

- based diesel for 2013 at 1.28 billion gallons of biomass

- based diesel. 23 This national volume is then used to determine the applicable percentage standard that determines the specific renewable volume ob ligations for refiners and importers. Subsequently, EPA received two Petitions for Reconsideration requesting that EPA reconsider the final rule setting the 2013 biomass

- based diesel volume requirement at 1.28 bill gal. 24 After review and consideration of the issues raised by petitioners, EPA denied both petitions. 25

In today's action we are proposing an applicable volume of 1.28 billion gallons biomass

based diesel for 2014 and 2015

. In proposing the 2015 applicable volume of biomass

- based diesel, we are not at this time proposing the percentage standards that would apply to obligated parties in 2015

. T he percentage standards for 201 5 will be proposed in a subsequent rulemaking as required by the statute once the requisite gasoline and diesel fuel vol umes for 2015 are

determined.

A. Statutory Requirements

Section 211(o)(2)(B)(i) of the Clean Air Act specifies the applicable volumes of renewable fuel on which the annual percentage standards must be based, unless the applicable

volumes are waived or adjusted by EPA in accordance with the Act. 26 Applicable volumes are provided in the statute for years through 2022 for cellulosic biofuel, advanced biofuel, and total

renewable fuel. For biomass

- based diesel, applicable volumes are provided through 2 012. For years after those specified in the statute (i.e. 2013+ for biomass

- based diesel and 2023+ for all others), EPA is required under 211(o)(2)(B)(ii) to determine the applicable volume, in coordination with the Secretary of Energy and the Secretary o f Agriculture, based on a review of the implementation of the program during calendar years for which the statute specifies the applicable volumes and on analysis of the following factors :

• The impact of the production and use of renewable fuels on the e nvironment, including on air quality, climate change, conversion of wetlands, ecosystems, wildlife habitat, water quality, and water supply;

• The impact of renewable fuels on the energy security of the United States;

• The expected annual rate of future commercial production of renewable fuels, including advanced biofuels in each category (cellulosic biofuel and biomass

- based diesel);

• The im pact of the use of renewable fuels on other factors, including job creation, the price and supply of agricultural commodities, rural economic development, and food prices.

T he statute also specifies that the applicable volume of biomass

- based diesel cannot be less than the applicable volume for calendar year 2012, which is 1.0 bill gallons. The statute does not, however, establish any other numeric criteria or overarching go als for EPA to achieve in setting the applicable volumes in years after those specifically set forth in the provision.

Finally, the statute also specifies the timeframe within which these volumes must be promulgated: the applicable volumes must be established no later than 14 months before the first year for which such applicable volume will apply. We did not propose a 2014 volume for

biomass

- based diesel in the February 7, 2013 NPRM because at that time we were still evaluating the potential marke t impacts of current production levels. In order to provide sufficient time for this evaluation, we delayed our proposal for the 2014 volume requirement for

biomass

- based diesel. Consequently, today we are proposing volume requirements for both 2014

and 2015.

B. Compliance with 2013 Volume Requirement of 1.28 Billion Gallons

In making a determination regarding the volume requirement for biomass

- based diesel to propose for 2014 and 2015, we first investigated the recent historical and current circumst ances in the biodiesel market. According to data collected through the EPA

- Moderated Transaction System (EMTS) production of biodiesel in 201 2 exceeded 1. 14 bill gal. 27 This demonstrates that the industry was able to meet the applicable 201 2 volume requir ement of 1 b ill gal. It also provides evidence that the industry will meet the 1. 28 bill gal requirement in 2013. A dditional

volumes above 1. 28 bill gal are possible in 2013, and may be used to help meet the advanced biofuel standard. Indeed current pro duction rates in the biodiesel industry for the first seven months of 2013 were 25% above monthly production rates for the same time period in 2012 and

are consistent with a total production volume of at least 1.6 bill gal for 201 3

Page 44 of 111 While annual production volume has been increasing, a review of EIA’s Monthly Biodiesel Production Reports 29 since 2009 indicates that there has been some variability both in monthly production volume and in the number of facilities producing that volume. For example, there were significant biodiesel facility closures during the 2009 and 2010 calendar years. Since that time the overall number of biodiesel facilities in operation has stabilized and overall capacity in the biodiesel industry has remained stable from 2009

- 2012 at more than 2 billion gallons. It is also clear that overall industry

- wide utilization rates have increased during this time period from 25% in 2009 to approximately 46% in both 2011 and 2012. Thus it is clear that total production capacity at fac ilities already operating is above 1.28 bill gal. There are also indications that new or idle facilities have begun production in response to the 1.28 bill gal mandate for 2013. Specifically, EIA’s monthly reports indicate that nine additional producers have become operational in the U.S. since the rule for 2013 biomass

- based diesel was finalized. 30 The latest EIA monthly biodiesel report, available for July 2013, indicates that U.S. production was 128 million gallons in July, and came from 111 biodiesel plants in 38 states with total operating capacity of 2.1 bill gal per year. 31 As described in Section IV.B.2.b, total biodiesel production by the end of 2013 could be as high as 1.7 bill gal, and the facilities contributing to this production collectively have a capacity of well over 2 bill gal.

Further discussion of the factors we must consider in the context of the biomass

- based diesel volume of 1.28 bill gallons for 2013 is contained in both the final rule adopting this level

for 2013 32 and in EPA’s den ial of two petitions requesting the Agency reconsider the 2013

biomass

- based diesel final rule. 33 As discussed in that final rule, the assessment of these factors supported a volume of 1.28 bill gallons for 2013. As w e would expect that the impacts of 1.2 8 bill gal in 2014 and 2015 would not be materially different , we are not repeating the discussion of those analyses here. However

, we specifically request data and analyses suggesting that the factors we considered in 2013 have changed significantly for 2014 or 2015

.

C. Determination of Applicable Volume for 2014 and 2015

T he biodiesel industry has clearly demonstrated that it can produce the volumes of

biomass

- based diesel up to the minimum required by the statute, and that 1.28 bill gal of

biodiesel is readily attainable . We have no real concerns that a level of 1.28 billion gallons will

Page 45 of 111 be achieved effectively in 2013, and that once it is met this level of production and consumption

can a lso be achieved in years after 2013 . Production costs associated with 1.28 bill gal of biodiesel could be affected by various factors, including the expiration of the biodiesel tax credit and projected lower soy oil prices.

EPA’s evaluation of the appli cable volume that we should set for biomass

- based diesel takes into account the context of the larger advanced biofuel and total renewable fuel volume requirements. The biomass

- based diesel standard is a subset of both the advanced biofuel and

total rene wable fuel standards, and biomass

- based diesel volumes can be used to meet all three standards. As discussed in Section IV below, we are proposing to reduc e the applicable volumes of advanced biofuel and total renewable fuel. The reductions are designed to address several factors that affect achievement of the volume goals that Congress established in the statute for these categories of renewable fuel. These factors include limitations in production or importation of the necessary volumes, and factors th at limit supplying those volumes to the vehicles that can consume them. These same factors impact our consideration of the biomass

based diesel volume requirement for 2014. For example, EPA considers the availability of feedstocks for production of biodi esel.

More importantly, the production and use of biomass

- based diesel can be supported by both the need to comply with the required volume for biomass

- based diesel as well as the need to comply with the required volume for advanced biofuel or even the volume for total renewable fuel. This provides EPA additional flexibility in considering the appropriate national volume to

set for the biomass

- based diesel volume requirement, as this requirement is not the only mechanism in the RFS program that can sup port production and use of biomass

- based diesel. For example, while the applicable volume that EPA sets for biomass

- based diesel will ensure

that at least that volume of biomass

- based diesel would be produced and used, the advanced biofuel standard provid es an alternative potential source of support for production and use of

additional volumes of biomass

- based diesel. It does this because obligated parties have

discretion whether to choose biomass

- based diesel or another advanced biofuel to satisfy their advanced biofuel obligation , and because the diesel pool can accommodate considerably more than 1.28 bill gal of biodiesel

. EPA believes there is value in providing obligated parties increased flexibility in how they meet their required volume obligations in 2014. As discussed in Section IV, EPA is reducing the statutory volumes of advanced biofuel and total renewable fuel

b ased on concerns of inadequate domestic supply of these renewable fuels. Providing obligated parties additional flexibility to address future supply circumstances is of increased importance

under these circumstances.

In setting the applicable volume f or biomass

- based diesel for 2013, EPA discussed various impacts of requiring volumes of biomass

- based diesel in light of the relevant factors to be considered under CAA section 211(o)(2)(B)(ii). 34 We believe this analysis continues to be

approp riate, and supports the proposed applicable volume of biomass

- based diesel for 2014. In considering all of these factors, we see no need to reduce the minimum biomass

- based diesel volume requirement from 2013 levels. We have a high degree of conf idence that this volume of 1.28 bill gal could be achieved effectively without any real risk of production or supply problems.

Page 46 of 111 At the same time, as discussed above, the volume requirem ent for biomass

- based diesel is nested within the advance biofuel standards that we are proposing to reduce in 2014. W e believe

that volumes of biomass

- based diesel above 1.28 billion gallons can, and likely will, be produced in 2014 to meet the requireme nts of the advanced biofuel standard , though the degree to which this occurs will also depend on whether the biodiesel tax subsidy is extended beyond December 31, 2013

. We do not expect that there would be a significant difference between additional

volum es of biomass

- based diesel above 1.28 billion gallons and other advanced biofuels, as far as the overall impact of those fuels in terms of the factors we are required to consider under section 211(o)(2)(B)(ii). Any such differences would also be hard to q uantify. At the same time, providing obligated parties the discretion to choose the method to comply with their advanced biofuel volume requirement most appropriate for their circumstances is likely to reflect the most

effective or efficient way to achiev e the advanced biofuel volume requirements given the market circumstances present in 2014. In addition, as noted above, providing obligated parties additional flexibility to address the 2014 supply circumstances is of increased importance under

the circum stances surrounding supply and consumption as discussed in Section IV. Therefore we are not proposing to increase the volume of biomass

- based diesel that will be required in

2014 and 2015. 35

We invite comment on any different approaches that might be ap propriate for balancing the factors noted above, including requiring an increase in the minimum volume of biomass

based diesel above 1.28 billion gallons in both 2014 and 2015. As discussed above, volumes above 1.28 bill gal should be available, whether t o meet a minimum biomass

- based diesel requirement or the advanced biofuel requirement

. Requiring a minimum volume greater than 1.28 bill gal would place less emphasis on the benefits of preserving flexibility in how the required volume of advanced biofuel is achieved, and more emphasis on production of biomass

based diesel, without specifi c regard to the existence of a tax subsidy or to potential supplies of

carryover biomass

- based diesel RINs generated in 2013. We invite comment on all aspects of this issue, including to what extent, if any, carryover biomass

- based diesel RINs from 2013

w ould affect production levels of biomass

- based diesel or other advanced biofuels in 2014, whether to meet the 1.28 bill gal biomass

- based diesel volume or to achieve higher levels as a part of achieving the advanced biofuel requirement. We also seek comme nt on how EPA should

take such information on biomass

- based diesel carryover RINs into account when setting the se volume requirements and the degree to which those carryover RINs support the goal of maintaining flexibility in how obligated parties meet the advanced biofuel mandate

.

In the overall context of the RFS program, the level of the biomass

- based diesel applicable volume can be seen as the minimum amount of biomass

- based diesel that is required, recognizing that additional volumes of biomass

- based diesel may be used, along wi th other advanced biofuels, to satisfy the volume requirements for advanced biofuel and total renewable

fuel. Having considered the statutory factors, in the context of proposing the volume requirements for advanced biofuel and total renewable fuel , we be lieve the minimum required

35 While the statute requires EPA to establish the applicable volume of cellulosic biofuel at projected pro duction levels, this is not the case with respect to the applicable volume of biomass

. Proposed National Volume Requirements for Advanced Biofuel and Total

Renewable Fuel for 201 4

As described in Section I, the national volumes of renewable fuel to be used under the RFS program each year are specified in CAA 211(o)(2). For 201 4 , the applicable volume of

advanced biofuel is 3 .75 bill gal and the applicable volume of total renewable fuel is 18.15 b ill gal. However, two statut ory provisions authorize EPA to reduce these volumes . EPA may reduce these volumes if it reduces the applicable volume for cellulosic biofuel, or if the criteria are met under the general waiver authority. 36 We are proposing t o exercise our discretion under these provisions to reduc e the applicable volumes of advanced biofuel and total renewable fuel to address several factors that affect achievement of the volume goals that Congress established in the statute. These factors include limitations in production or importation of the necessary volumes, and fac tors that limit supplying those volumes to the vehicles that can consume them. Based on a detailed analysis of these limitations, we are proposing reductions in the statutory

volumes of both advanced biofuel and total renewable fuel as shown below.

Table IV

- 1 Proposed Volumes for 2014 (billion gallons)

Statutory volume Proposed volume Range Mean

Advanced biofuel 3.75 2.00

- 2.51 2.20

Total renewable fuel 18.15 15.00

- 15.52 15.21

We are proposing to use a combination of the cellulosic biofuel waiver authority and the general waiver authority to ensure that the proposed volumes are reasonably achievable given limitations in the volume of ethanol that can be practically consumed in m otor vehicles considering constraints on the supply of higher ethanol blends to the vehicles that can use them and other limits on ethanol blend levels approved for use in motor vehicles and the volume of non

- ethanol renewable fuels that we expect would be reasonably achievable. To accomplish this, we are proposing an approach involving the following three steps:

• First, we would determine the total volume of ethanol that can reasonably be supplied

to and consumed in the transportation sector as both E10 and higher ethanol blends

such as E85. We would then add to this the volume of all non

- ethanol biofuels that
we expect c ould be reasonably available for meeting all four of the applicable volume requirements (cellulosic biofuel, biomass

- based diesel, adv anced biofuel, and total renewable fuel). This first step would determine the volume of renewable fuel that can adequately be produced and supplied to consumers in light of limitations on the consumption of ethanol (commonly referred to as the “ethanol bl endwall”) and other relevant constraints, and would form the basis for the required volume of total

renewable fuel as adjusted pursuant to EPA’s waiver authorities

.

36 See CAA section 211(o)(7)(D) and (A)*** EO12866 Review

Page 49 of 111 • Second, we would determine the volumes of all sources of advanced biofuel that could be reasonably achieved to ensure that the required volume of advanced biofuel be set no higher than the volume that is projected to be reasonably available

.

• Third, we would determine an appropriate volume of advanced biofuel at or below

th e projected available volume determined in the second step. This volume would include the required volume of cellulosic biofuels and biomass

- based diesel, which are set separately, as well as any additional volumes of non

- ethanol advanced biofuels projecte d to be reasonably achievable . This approach would account for the contribution of ethanol volumes in the advanced biofuel category to the supply

concerns related to total renewable fuel , including considerations of both production and consumption. While ensuring that both advanced biofuel and non

- advanced renewable fuels play a role in addressing the ethanol blendwall, it would also support Congress's goal in the RFS program of continued growth in the advanced biofuel category as reflected in the volume requirements established in the statute. As

discussed in detail in Section IV.C.2 , we have examined several alternative approaches to this third step, but we believe this approach best accommodates the objectives of the RFS program, while accounting for t he limitations in the ability to produce and consume renewable fuels. We request comment, however, on alternative approaches and on all aspects of the framework discussed in this section.

We anticipate that the framework described in this section woul d apply not only to 2014, but to subsequent years as well. The specific estimates of volumes for each potential source of renewable fuel would be different in each future year, but the manner in which we aggregate those estimates to determine appropriate volume requirements would follow the overall approach

described above. I f circumstances differ substantially from those described here, or if further analysis suggests that our proposed approach is inadequate, we may consider the need for

additional measu res.

A. Statutory Authorities for Reducing Volumes to Address Biofuel Availability and

the Ethanol Blendwall

In establishing the annual volume objectives in the statute, Congress intended that volumes of renewable fuel, advanced biofuel, and cellulosic biofuel increase every year through 2022, and that volumes of biomass

- based diesel be at least equal to the statutory volume for 2012, while granting EPA discretion to increase the biomass

- based diesel volume based on consideration of several specified fa ctors. However, Congress recognized that circumstances could arise that might require a reduction in the volume objectives specified in the statute as evidenced by the different waiver provisions in CAA 211(o)(7). As described in more detail below, we be lieve that limitations in production or importation of qualifying renewable fuels, and factors that limit supplying those volumes to the vehicles that can consume them, both constitute circumstances that warrant a waiver under section 211(o)(7) as discusse d below. With regard to the ethanol blendwall, a decrease in total gasoline consumption since EISA was enacted in 2007, coupled with limitations in the number and geographic distribution of retail stations that offer higher ethanol blends such as E85 and the number of FFVs that have access to*** EO12866 Review

Page 50 of 111 E85, as well as other market factors, combine to place significant restrictions on the volume of

ethanol that can be supplied to and consumed in the transportation sector . Based on the types of

renewable fuel that we project are likely to be available in 2014 and the volume that is likely to

be non

- ethanol, we believe that the ethanol blendwall represents a circumstance that warrants a

reduction in the mandated volumes for 2014.

The statute provides two separate aut horities that permit EPA to reduce volumes of advanced biofuel or total renewable fuel under certain conditions: the cellulosic waiver authority and the general waiver authority. Applying a combination of these two authorities is the most appropriate way to address limitations in production or importation of the necessary volumes, and factors that limit supplying those volumes to the vehicles that can consume them, including the ethanol blendwall. This section discusses both of these statutory authorities and the manner in which we believe they can be used together to set standards for 2014.

1. Cellulosic Waiver Authority

Under CAA section 211(o)(7)(D)(i), if EPA determines that the projected volume of cellulosic biofuel production for the following y ear is less than the applicable volume provided in the statute, then EPA must reduce the applicable volume of cellulosic biofuel to the projected volume available during that calendar year. Under such circumstances, EPA also has the

discretion to reduce t

he applicable volumes of advanced biofuel and total renewable fuel by an

amount not to exceed the reduction in cellulosic biofuel.

Section 211(o)(7)(D)(i) provides that “ [f] or any calendar year in which the Administrator makes such a reduction, the Adm inistrator may also reduce the applicable volume of renewable fuel and advanced biofuels requirement established under paragraph (2)(B) by the same or a lesser volume.” Thus Congress authorized EPA to reduce the volume of total renewable fuel and

advanced biofuel. As EPA has discussed before, t his indicates a clear Congressional intention

that under this provision EPA may reduce both the total renewable and advanced biofuel volume together, not one or the other.

As described in the May 26, 2009 NPRM f or the RFS regulations , we do not believe it would be appropriate to lower the advanced biofuel standard but not the total renewable standard, as doing so would allow conventional biofuels to effectively be used to meet the standards that Congress specific ally set for advanced biofuels. 37 EPA interprets this provision as authorizing EPA to reduce both total renewable fuel and advanced biofuel, by the same amounts,

if EPA reduces the volume of cellulosic biofuel. Using this authority t he reductions in total renewable fuel and advanced biofuel can be up to but no more than the amount of reduction in

the cellulosic biofuel volume. Further discussion of this provision can be found in the final rule establishing the 2013 RFS standards. 38

The statute does not p rovide any explicit criteria that must be met or factors that must be considered when making a determination as to whether and to what degree to reduce the

Page 51 of 111 advanced biofuel and total renewable fuel applicable volumes based on a reduction in cellulosic

biof uel volumes under CAA section 211(o)(7)(D)(i). EPA can consider the criteria described in sections 211(o)(2)(B)(ii) and 211(o)(7)(A) in determining appropriate reductions in advanced biofuel and total renewable fuel under the cellulosic waiver authority a t section 211(o)(7)(D)(ii), or any other factors that may be relevant. However, EPA must provide a reasoned explanation for any decision to reduce the advanced biofuel and total renewable fuel volume requirements

under the cellulosic biofuel waiver author ity.

2. General Waiver Authority

CAA 211(o)(7)(A) provides that EPA

, in consultation with the Secretary of Agriculture (USDA) and the Secretary of Energy (DOE) , may waive the applicable volume requirements of the Act in whole or in part based on a petition by one or more States, by any person subject to the requirements of the Act, or by the EPA Administrator on her own motion . Such a waiver must

be based on a determination by the Administrator, after public notice and opportunity for

comment

, that :

• I mplementation of the requirement would severely harm the economy or the environment of a State, a region, or the United States; or

• T here is an inadequate domestic supply.

In today's NPRM, we are proposing to use the general waiver authority to w aive the applicable volume requirements based on the statute's authorization for the Administrator to act on her own motion. We have initiated discussions with both USDA and DOE on the proposed approach to determining the applicable volume requirements th at is described in this section.

Because this provision provides EPA the discretion to waive the volume requirements of

the Act " in whole or in part, " we interpret this section as granting authority to waive any or all of the four applicable volume requi rements in appropriate circumstances. Thus, for example, unlike the cellulosic waiver authority, a reduction in total renewable fuel pursuant to the general waiver authority would not automatically result in the same reduction in advanced biofuel , and

wou ld not be limited by the reduction in cellulosic biofuel.

EPA has not previously interpreted or applied the waiver provision in CAA section 211(o)(7)(A)(ii) related to " inadequate domestic supply ." 39 As explained in greater detail below,

we believe that this ambiguous provision is reasonably and best interpreted to encompass the full range of constraints that could result in an inadequate supply of renewable fuel to the ultimate consumers, including fuel infrastructure and other constraints. This would include, for instance, factors affecting the ability to produce or import qualifying renewable fuels as well as factors affecting the ability to distribute, blend, dispense, and consume those renewable fuels.

The waiver provision at CAA 211(o)(7)(A)(ii) is ambiguous in several respects. First, it does not specify what the general term " supply " refers to. The common understanding of this

39 EPA has applied the waiver provision in section 211(o)(7)(A)(i) related to severe harm to the economy. See 77 FR 70752 (November 27, 2012), 73 FR 47168 (August 13, 2008)

.*** EO12866 Review

Page 52 of 111 term is an amount of a resource or product that is available for use by the person or place at

issue. 40 Hence the eval uation of the supply of renewable fuel, a product, is best understood in terms of the person or place using the product. In the RFS program, various parties interact across several industries to drive the ultimate use of renewable fuel by consumers of

tra nsportation fuel

. For example, supply ing renewable fuel to obligated parties and terminal

blenders is one part of this process, while supply ing renewable fuel to the ultimate consumer as part of transportation fuel is a different and later aspect of this process . This is clearly the case with respect to the renewable fuels ethanol and biodiesel, which are typically supplied to the obligated parties and terminals as a neat fuel, but in almost all cases are supplied to the consumer as a blend with conventional fuel (ethanol and gasoline or biodiesel and diesel). The waiver provision does not specify what product is at issue (for example, neat renewable fuel or blended

renewable fuel wit

h transportation fuel) or the person or place at issue (for example, obligated party or ultimate consumer), in determining whether there is an "inadequate domestic supply

. "

The waiver provision also does not specify what factors are relevant in determini ng the adequacy of the supply. A dequacy of the supply would logically be seen in terms of the parties who use the supply of renewable fuel. Adequacy of supply could affect various parties, including obligated parties, terminal operators, and consumers. Adequacy of supply with respect to the consumer might well involve consideration of factors different from those involved when considering adequacy of supply to the obligated parties. We believe that interpreting this waiver provision as authorizing EPA t o consider the adequacy of supply of renewable fuel to all of the relevant parties, including the adequacy of supply to the ultimate consumer of transportation fuel, is consistent with the common understanding of the terms used in this waiver provision,

es pecially in the context of a fuel program that is aimed at increasing the use of renewable fuel by consumers

. In our view, this is the most reasonable and appropriate construction of this ambiguous language in light of the overall policy goals of the RFS program.

EPA has reviewed other fuel related provisions of the Clean Air Act with somewhat similar waiver provisions , and they highlight both the ambiguity of th e RFS general waiver provision and the reasonableness of applying it broadly to include adeq uacy of supply to the ultimate consumer of transportation fuel

. For example

, CAA section 211(k)(6)( A ) (ii) allows EPA to defer application of reformulated gasoline (RFG) requirements in a state that opt s in to

the RF G program if EPA determines that " there is insufficient domestic capacity to produce reformulated gasoline. " A related RFG waiver provision concerning the application of RFG requirements in the Ozone Transport Region, section 211(k)(6)(B)(i) and (iii), provides for a waiver of RFG requirements based on "insufficient capacity to supply reformulated gasoline." For these RFG waiver provisions, Congress more clearly and explicitly indicated that the capacity to supply RFG could include consideration of factors beyond those concerning the capacity t o produce RFG. In t he language of t

h e RFS general waiver provision , in comparison, Congress use d a single, broader and clearly ambiguous phrase

- "inadequate domestic supply "

- without elaboration or clarification as to whether it refers solely to product ion capacity or also

40 For example, see http://oxforddictionaries.com/us/definition/american_english/ supply ( a stock of a resource from which a person or place can be provided with the neces sary amount of that resource: " T here were fears that the drought would limit the exhibition’s water supply .”); http://www.macmillandictionary.com/us/dictionary/american/supply ( “ A limited oil supply has made gas prices rise.” and “Aquarium fish need a constant supply of oxygen. ”).*** EO12866 Review

- Revised version

Page 53 of 111 includes additional factors relevant to the ability to supply the fuel to various persons such as the

ultimate consumer

. A s in the RFG provision, however, the adequacy of supply referred to in the RFS general waiver provision can logi cally

- and we believe should

- be read to include factors beyond capacity to produce that impact the ability of consumers to use the fuel as a transportation fuel.

CAA section 211(c)(4)(C)(ii) provides EPA with waiver authority to address "extreme and unusual fuel or fuel additive supply circumstances ... which prevent the distribution of an adequate supply of the fuel or fuel additive to consumers." The supply circumstances must be the result of a natural disaster, an Act of God, a pipeline or ref inery equipment failure or another event that could not reasonably have been foreseen, and granting the waiver must be "in the public interest." In this case, Congress clearly specified that the adequacy of the supply is judged in terms of the availabilit y of the fuel for use by the ultimate consumer, and includes

consideration of the ability to distribute the required fuel or fuel additive to the ultimate

consumer. Although the RFS waiver provision does not contain any such explicit clarification from Congress, its broad and ambiguous wording provides EPA the discretion to reasonably interpret the scope of the RFS waiver provision. EPA’s interpretation of the RFS waiver

pro vision is consistent with the view

, expressed more explicitly in the section 211(c) waiver

, that the adequacy of the supply of a fuel or fuel additive can reasonably be judged in terms of availability for use by the consumer, and can include consideration of the capacity to distribute the product to the ultimate consumer.

CAA section 211(m)(3)(C) allows EPA to delay the effective date of oxygenated gasoline requirements for certain carbon monoxide nonattainment areas if EPA finds " an inadequate

dome stic supply of, or distribution capacity for, oxygenated gasoline . . . or fuel additives " needed to make oxygenated gasoline. Here , Congress chose to expressly differentiate between

" domestic supply " and " distribution capacity ," indicating that each of t hese elements was to be considered separately

. This would indicate that the term inadequate supply , although ambiguous for the reasons discussed above, could in appropriate circumstances be read as more limited in scope. In contrast to the RFS waiver pro vision, the section 211(m) waiver provision includes

additional text that makes clear that EPA’s authority includes consideration of distribution capacity

- reduc ing the ambiguity inherent in using just the general phrase "inadequate domestic supply." Pr esumably this avoids a situation where ambiguity would result in an overly narrow administrative interpretation. The oxygenated gasoline waiver provision is also instructive in that it clarifies that it applies separately to both finished oxygenated fuel and to oxygenated fuel blending components. That is, there could be an adequate supply of the oxygenate, such as ethanol, but not an adequate supply of the blended fuel which is sold to the consumer. The RFS waiver provision employs the phrase " inadequat e domestic supply " without further specification

or clarification

, thus provid ing EPA the discretion to determine whether the adequacy of the supply of renewable fuel can reasonably be judged in terms of availability for use by the ultimate consumer, inclu d ing consideration of the capacity to distribute the product to the ultimate consumer. In contrast to the section 211(m) waiver provision, Congress arguably did not mandate that the RFS waiver provision be interpreted as providing authority to address pro blems affecting the supply of renewable fuel to the ultimate consumer. However

, the RFS waiver*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 54 of 111 provision does provide EPA the discretion to adopt such an interpretation, resulting in a policy approach consistent with that required by the less ambiguous se ction 211(m) waiver provision. 41

As the above review of various waiver provisions in Title II of the Clean Air Act makes clear, Congress has used the term s " supply " and "inadequate supply" in different waiver provisions. In the RFS general waiver provision, Congress spoke in general terms and did not address the scope of activities or persons or places that are the focus in determining the adequacy of supply. In other cases, Congress provided, to varying degrees, more exp licit direction. Overall, the various waiver provisions lend support to the view that it is appropriate, where Congress has used just the ambiguous phrase "inadequate domestic supply" in the general waiver provision, to consider supply in terms of distrib ution and use by the ultimate consumer, and that the term "inadequate supply" of a fuel need not be read as referring to just the capacity to produce renewable fuel or the capacity to supply it to the obligated parties.

We are aware that prior to fin al adoption of the Energy Independence and Security Act of

2007

, Congress had before it bills that would have provided for an EPA waiver in situations

where there was " inadequate domestic supply or distribution capacity to meet the requirement. " 42

EPA is n ot aware of any conference or committee reports , or other legislative history, explaining why Congress ultimately enacted the language in EISA in lieu of this alternative formulation.

There is no discussion , for example, of whether Congress did or did not want EPA to consider distribution capacity, whether Congress believed the phrase " inadequate domestic supply " was sufficiently broad that a reference to distribution capacity would be unnecessary or superfluous

, or whether Congress considered the alternat ive language as too limiting, since it might suggest that other types of constraints on delivering renewable fuel to the ultimate consumer should not be considered for purposes of granting a waiver. 43 Given the lack of interpretive value typically given to a failure to adopt a legislative provision, and the lack of explanation in this case, we find

the legislative history to be uninformative with regard to Congressional intent on this issue. It does not change the fact that the text adopted by Congress, wh ether viewed by itself or in the context of other fuel waiver provisions, is clearly ambiguous.

We believe the term " inadequate domestic supply " should be interpreted to authorize EPA to consider the full range of constraints, including fuel infrastructure and other constraints,

t hat could result in an inadequate supply of renewable fuels to consumers

. Under this interpretation, we would not limit ourselves to consideration of the capacity to produce or import renewable fuels but would also consider practical and other constraints related to the fuel delivery infrastructure and their effect on the volume of qualifying renewable fuel that would be supplied to the ultimate consumer.

41 In CAA section 211(h)(5)(C)(ii), Congress authorized EPA to delay the effective date of certain changes to the federal requirements for Reid vapor pressure in summertime gasoline, if the changes would result in an "insufficient supply of gasoline" in the a ffected area. As with the RFS general waiver provision, Congress did not specify what considerations would warrant a determination of insufficient supply. EPA has not been called upon to apply this provision to date and has not interpreted it.

Page 55 of 111 This interpretation is consistent with the provisions of section 211(o) and promotes Congress’s purposes in establishing the RFS program, which are to ensure that certain volumes of renewable fuel are used by the ultimate consumer as a replacement for the use of fossil based transportation fuel. 44 The RFS program does not achieve the desired benefits unless renewable fuels are actually used to replace fossil based transportation fuels. For example, the greenhouse

gas reductions an d energy security benefits that Congress sought to promote through this

program are realized only through the use by consumers of renewable fuels that reduce or replace fossil fuels present in transportation fuel. Imposing RFS volume requirements on oblig ated parties without consideration of the ability of the obligated parties and other parties to

deliver the renewable fuel to the ultimate consumers, would achieve no such benefits and would fail to account for the complexities of the fuel system that deli vers transportation fuel to

consumers. We do not believe it would be appropriate to interpret the RFS general waiver provision more narrowly and limit EPA's consideration of factors related to the distribution and use of renewable fuels by the ultimate co nsumers of these fuels

.

We invite comment on all aspects of our proposed interpretation of the waiver provision

based on " inadequate domestic supply. " Whether or not circumstances projected for 2014 justify

a waiver on this basis is discussed in Section s IV.B and IV.C

.

3. Combining Authorities for Reductions in Advanced Biofuel and Total Renewable

Fuel

The two primary drivers that we have considered in today's NPRM for reductions in the required volumes are limitations in the availability of qualify ing renewable fuels and factors that constrain supplying those volumes to the vehicles that can consume them. These two drivers are

both relevant forms of inadequate domestic supply , which authorize reductions under the general waiver authority and can also justify reductions under the cellulosic biofuel waiver authority. We believe that reducing both total renewable and advanced biofuel are appropriate responses to these circumstances, and we propose to use a combination of the two waiver authorit ies discussed above to achieve this result as neither authority independently is sufficient to justify the necessary volume reductions. As discussed in Section II, EPA is proposing to reduce the applicable volume of cellulosic biofuel based on a projectio n of production for 2014. Given this reduction in the cellulosic biofuel volumes, EPA is also proposing to reduce the applicable volume of advanced biofuel using the cellulosic biofuel waiver authority in Section 211(o)(7)(D)(i). We are proposing a large r reduction in total renewable fuel volume than in the advanced biofuel volume. In effect one part of the reduction in total renewable fuel would be based on both the general waiver authority and the cellulosic biofuel waiver authority, and the

44 See CAA section 211(o)(1)(I) (renewable fuel defined as “fuel ... used to replace or reduce the quantity of fossil fuel present in a transportation fuel”), section 211(o)(2)(A)(i) (EPA’s regulations must “ensure that transportation

fuel sold or introduced into commerce in the United States ... conta ins at least the applicable volume of [renewable fuels]”). Also see CAA section 211(o)(1)(A), definition of “additional renewable fuel.” As one example, in the RFS program fuels with multiple end uses such as biogas or electricity are not considered a r enewable fuel absent a demonstration that they will be used by the ultimate consumers as transportation fuel. As noted above, ethanol is almost always used as a renewable fuel in the form of E10 or higher, not as neat ethanol. The supply of neat ethanol, or biogas or electricity, does not by itself determine the supply of the fuel ethanol used as a transportation

fuel.*** EO12866 Review

Page 56 of 111 remainder of the reduction in total renewable fuel would be based solely on the general waiver authority. Below we discuss the basis for each of the proposed volume reductions.

B. Determination of Reductions in Total Renewable Fuel

As a first step in our proposed framework for setting the applicable volumes for total renewable fuel and advanced biofuel, we would estimate the volume of ethanol that can reasonably be expected to be available and consumed and the volume of non

- ethanol renewable

fuel that can reasonably be expected to be available and consumed. Taken together, these two considerations provide the basis for the volume of total renewable fuel that we are proposing to require. Our objective is that the proposed requirement would reflect a realis tic projected estimate of renewable fuel supply, based to the greatest extent possible on data and real world

circumstances.

For ethanol, the primary issue is the use of the fuel in the transportation sector, as the purpose of the RFS program is to ens ure that renewable fuels are used to replace or reduce the use of fossil fuel based transportation fuel. 45 For ethanol blends, there are legal constraints on the amount of ethanol that can be blended into gasoline and practical constraints on the volume

of ethanol that can be consumed as transportation fuel , notwithstanding the ability to produce higher volumes. For non

- ethanol renewable fuels, the primary issue is the availability of volumes of the renewable fuel, and much less so the ability to consume i t in the transportation sector if it is available. For purposes of this proposal, we generally refer to the consumption concerns related to ethanol, and the availability concerns related to non

- ethanol forms of renewable fuel, recognizing the primary conc ern that is raised for each of these types of

renewable fuel.

With regard to consumption concerns related to ethanol, it is important to note that the overall pool of gasoline into which ethanol must be blended to achieve EISA’s statutory volume requirem ents is significantly smaller now than it was projected to be prior to enactment of EISA in 2007, which established both the revised RFS program requirements and the mandated significant increases in vehicle fuel economy standar ds

. The total demand for gasoline has been decreasing over the intervening years due to the recent GHG and CAFE standards for vehicles

, broader economic factors, and fuel prices

. Comparing the Reference case projections for 2014 gasoline demand in EIA's 2007 and 2013 Annual Energy Outlooks indicates that in the summer

of 2006, when the AEO2013 Reference case was developed , the projected 2014 gasoline energy demand was 18.68 Quad Btu and could have absorbed 15.43 bill gal of ethanol as E10, while in the summer of 2012, when the AEO2013 Reference case was developed, the projected 2014 gasoline energy demand is 15.94 Quad Bt u and could absorb 13.17 bill gal ethanol as E10. The difference between these two projections thus represents about 2.3 bill gal of ethanol. That is, the gasoline pool will be able to absorb about 2.3 bill gal less ethanol as E10 in 2014 than it would have been possible to absorb if the gasoline use projection in AEO2007 had been realized

. If 15.43 bill gal of ethanol were to be consumed in 2014, the gasoline energy demand projected

1. Estimating Ethanol Volumes that Could Reasonably Be Consumed

The total volume of ethanol that could reasonably be consumed is a functio n of three

factors:

• The overall demand for gasoline

• The consumption of ethanol as E10, E15, and E85

• The presence of non

- oxygenated gasoline (E0)

In this section, we provide our assessment of the likely distribution of ethanol in gasoline, with a

pa rticular emphasis on potential volumes of E85 that could reasonably be achievable. We discuss and request comment on the assumption that the overall pool of gasoline is comprised of

E10 and E85 in 2014.

a. Projected Composition of 2014 Gasoline Suppl y

For the purposes of this proposed rule, we have assumed that all gasoline

- powered

vehicles and FFVs would use either E10 or E85. EPA has taken a series of regulatory steps to

en able E15 to be sold in the U.S. In 2010 and 2011, EPA issued partial waiv ers to enable use of

E15 in model year 2001 and newer vehicles, and in June of 2011, EPA finalized regulations to prevent misfueling of vehicles, engines

, and equipment not covered by the partial waiver decisions. However, based on information currently a vailable to the Agency, the volume of E15 being supplied in the market to date has been very limited. Therefore, to simplify the Comment [A3]: EO 12866 11/6: Suggested edits.

This should address the concern about introducing “inconsistency” by replacing the AEO2013 line in

the table with the latest information from STEO.*** EO12866 Review

Page 58 of 111 calculations and the discussion, we have assumed that the volume of E15 that is consumed in 2014 will be negligible, as there are currently very few retail stations offering E15. Any volumes of other intermediate blends, such as E30, are assumed to be sold through blender pumps into FFVs and are thus assumed to be part of the E85 volume consumed by FFVs.

We have not assumed that any gasoline would be E0 in 2014, since E10 is commonly used in nonroad engines just as it is used in cars and trucks. However, it is possible that a limited amount of E0 will be consumed if refiners are willing to provide it. If so, it would likely appear in premium gasoline, gasoline sold at marinas, or possibly unleaded motor gasoline used in light

aircraft that do not require leaded aviation gasoline . There are also several states that require unblended gasoline to be provided to terminals, though the intention of these requirements is to ensure that terminals have the option to blend ethanol into that gasoline. We are not aware of any data that would provide a direct estimate of the demand for E0, and given that any ongoing

demand for E0 i s likely to be small, we have not included it in our calculations of the total volume of ethanol that can be consumed in 2014. Nevertheless, we request information and data that would permit us to determine the volume of E0 used in the gasoline pool and t he appropriateness of incorporating some estimate of E0 into the final standards.

Aside from the volume of E85 that could reasonably be consumed in 2014, discussed in more detail in the next section, the gasoline pool would be comprised of E10. We have assumed that gasoline contains 10.0% denatured ethanol. This is consistent with survey data collected by the Alliance of Automobile Manufacturers indicating that the average ethanol content of all gasoline containing at least 5vol% ethanol is about 9.74%. This estimate is based on the use of

ASTM test method D

- 5599, which measures only the alcohol portion of the gasoline, not any denaturant that would have been included with the ethanol before it was blended into gasoline. Since the denaturant portion of ethanol is at least 2%, ethanol that is blended into gasoline contains less than 98% ethanol. When blended into gasoline, therefore, the E98 would result in a gasoline

- ethanol blend containing no more than 9.8% pure ethanol, or 10.0% denatured ethanol. Since all RFS ethanol volumes and RINs are also calculated on a denatured ethanol basis, it is thus appropriate to assume 10.0 percent. We request comment, however, on the accuracy of this assessment, including information with regard to whether and to wha t extent there are real world

constraints that limit the denatured ethanol content of E10 to a level lower than 10.0 percent, and if so, what the implications are with regard to the volume of ethanol that can reasonably be

consumed in 2014.

For E85 volum es, we recognize that the ethanol content could range from 51% to 83% according to ASTM D

- 5798

- 13. In today's NPRM we have assumed that the ethanol content of E85 is 74% consistent with the average value used by EIA in its Annual Energy Outlook. As for

E 10, we are treating the ethanol content of E85 as representing denatured ethanol.

b. Assessment of E85 Consumption

For purposes of determining the total renewable fuel volume requirement for 2014, consistent with the waiver authorities we are proposing to exercise in this action, we have

assessed the volume of E85 that can reasonably be supplied to and consumed in the*** EO12866 Review

Page 59 of 111 transportation sector

, based on a variety of factors that limit supplying E85 in the transportation

sector. Our assessment of the range of E85 volumes that can be reasonably consumed in 2014 considers factors such as infrastructure and consumer acceptance limitations as well a s the impact that the applicable standards could have on the relative price of E85 and E10. In projecting the likely range of E85 consumption in 2014 , we are not mandating that this amount of E85 be produced and consumed. The industries involved will dec ide what actually occurs in the marketplace. Obligated parties can take actions to facilitate the sale of E85, to the extent they can and choose to do so , or they can obtain RINs from non

- ethanol sources of renewable

fuel such as excess biodiesel, renewab le diesel, heating oil, and biogas. We expect that the parties involved will resolve this through their business decisions. Nevertheless, we acknowledge that the renewable fuel volumes established in this rulemaking will have an impact

on the volume of E 85 consumed in 2014.

There are a variety of sources we have considered in developing our estimate of the volume of E85 that could reasonably be supplied in the transportation sector in 2014. To begin with, we investigated available sources of informat ion on E85 production in 2012 and 2013. One report from EIA reported an E85 production volume of about 37 mill gal in 2012. 46 This volume is based on EIA survey data from forms EIA

- 810 (Monthly Refinery Report) and EIA

815 (Monthly Bulk Terminal and Blend er Report). It likely underestimates actual E85 consumption as these surveys do not capture other sources of E85 production, such as the following:

• E85 produced using reformulated gasoline (RFG) or reformulated gasoline blendstock (RBOB) as the petrole um component of the fuel

• E85 produced by refiners or blenders producing small quantities of E85

• E85 produced by parties such as ethanol production facilities

For the last category, we were able to estimate the potential volume of E85 produced in 2012 by ethanol facilities using data collected in the EPA

- Moderated Transaction System (EMTS). Ethanol production facilities are in general prohibited from separating RINs from the ethanol that they produce. However, if an ethanol producer blends its ethanol into gasoline to make a transportation fuel, it can separate the RINs from the ethanol used in this blending. If they do produce transportation fuel, it is very likely to be E85 rather than E10. Therefore, we assumed that all RINs sep a rated by ethanol p roducers represent ethanol blended as E85. Under this assumption, we determined that ethanol production facilities separated about 22 million RINs in 2012, which would correspond to about 30 mill gal of E85. When combined with the 37 mill gal

estimate fr om EIA for E85 produced by refineries and blenders, the total 2012 E85 production is

estimated to be about 70 mill gal.

At this time, available information regarding the volume of E85 production in 2013 is limited to the first half of the year. Using the same two sources of information described above

- EIA survey data for E85 production by refineries and blenders, and EMTS data to estimate E85 production at ethanol facilities

- we have estimated that total E85 production for the first half of

2013 was about 36 mill gal. However, both of these data sources demonstrate a strongly increasing trend over this timeframe. If this trend continues through the end of 2013 , total E85

Page 60 of 111 production could reach 100 mill gal in 2013. Furthermore, if this trend conti nued throughout 2014, total E85 production would reach 240 mill gal in 2014. 47 If this trend were further augmented to account for the rate of ongoing growth in both the number of retail stations offering E85 and in the number of FFVs in the fleet that wou ld occur over the remainder of 2013 and 2014, the projection for 2014 could be as high as 300 mill gal. 48 We anticipate that better

and more detailed information will be available

- including through th is notice and comment

process

- by the time we promulg ate the final rule. We solicit comment and information on 2013 consumption of E85 and its relevance to projecting reasonable levels of consumption in 2014.

It should be noted that historical consumption of E85 represents a small fraction of the

consump tion capacity of the FFVs currently in use. Even counting only those FFVs which have reasonable access to stations offering E85, their total consumption capacity is at least 1 bill gal.

The low historical consumption was most likely due to a combination of factors including limited access to retail stations offering E85

, the reduced ran ge of vehicles operating on E85

, and

the fact that E85 has historically been more expensive than E10 on an energy

- content adjusted

basis . A survey conducted by the National Association of Convenience Stores found that 71% of customers indicated that price was the most important factor in determining where they buy gasoline. 49 We believe the volume of E85 that can and will be sold in the future is likely highly depend ent on the price relationship between E10 and E85 and the availability of the fuel.

While historically E85 has been more expensive than E10 on an energy

- content adjusted basis, recent data collected by EIA suggests that at least in some parts of the co untry this price relationship between E10 and E85 may be changing. In a Today in Energy article published on September 19, 2013, EIA presented data showing that in a collection of Midwestern states E85 retail prices were less than E10 retail prices on an energy

- content adjusted basis in July 2013, the

most recent month for which information was available. 50 This change in price relationship between E10 and E85 coincides with reported increases in sales volumes of E85 in Iowa and Minnesota, two stat es in which E85 sales volumes are publically available. 51 If the conditions that have led to this price relationship continue in the future E85 sales volumes are likely to

continue to increase.

Moreover, as more gasoline stations sell E85 and more FFVs are sold in the United States the potential market for E85 will continue to increase. Through 2013 the number of stations selling E85 has been increasing at a rate of over 300 stations per year. 52 The size of the FFV fleet also increased by approximately 1 million vehicles in 2013. 53 If the recent pricing trends

Page 61 of 111 noted above persist and spread to other parts of the country the potential growth in E85 sales could be significant. Increasing E85 sales due to favorable pricing may also incentivize increasing g rowth rates in the number of stations selling E85 and the size of the FFV vehicle fleet. Such a scenario, however, is dependent on E85 being widely available at a price that is sufficiently lower than E10 to offset the lower energy content, increased refu eling frequency requirements, and other factors. If the price relationship between E10 and E85 reverts to historic levels significant growth in E85 sales volumes is unlikely.

The price relationship between E85 and E10 depends on many factors, but three of the most significant are the prices of corn, crude oil, and RINs. 54 Corn and crude oil are the primary contributors to the cost of production of the ethanol and gasoline, respectively, used in the United States. The RIN price functions as a mechanism to subsidize the price of ethanol sold as E85 until it is at or below price parity with gasoline on an energy

- equivalent basis even if the relative prices of corn and oil would not otherwise support such a pricing structure. The net effect of a reduction in the price of ethanol is that the price of E85 should fall relative to the price of E10, since E85 contains more ethanol than E10. The significant rise in the price of D6 (non

advanced) RINs and the subsequent drop in the retai l price of E85 relative to E10 over the course

of 2013 55 occurred at a time when corn and thus ethanol was relatively expensive, indicating that RINs are already functioning in this manner. The recent shift in E85 prices relative to E10 and

the simulta neous increase in E85 sales suggest the importance of paying careful attention to more

recent data concerning E85 prices and sales volumes when projecting E85 volumes in 2014.

While the more rec ent data is available from such a short period of time that it limits the confidence in using it to make projections for 2014, it nevertheless provides a basis for expecting that directionally, the lower the price of E85 compared to the price of E10, the g reater the likelihood that FFV owners will opt to purchase E85. In addition to the volumetric energy content of E85 compared to E10, the price difference may also need to accommodate the inconvenience of a greater frequency of refuelings for a vehicle ope rating on E85, the potentially the greater driving distance to a station offering E85, the unfamiliarity that FFV owners may have with E85 or their own vehicle's capabilities , and differences in the mix of vehicle types among FFVs compared to conventio nal (not flex fuel) vehicles . These factors may also vary from region to region across the U.S. based on state and local policies, making it challenging to develop correlations representing the nation as a whole. While we currently have insufficient

data to allow us to correlate sales volumes of E85 with its price relative to gasoline on an energy basis for the nation as a whole, information from Minnesota indicates a moderately strong correlation between E85/E10 price differential and E85 sales volumes. To further aid our projections for the final rule, w e request comment on the manner and extent to which RIN prices are affecting gasoline and E85 prices for the nation as a whole, and any associated changes in E85 consumption.

EPA is not in a position to estimate E85 consumption based on data or modeling involving the price relationship between E10 and E85. Therefore, in addition to information on

54 Other factors, including Federal and State taxes

, subsidies and distribution costs

, and relative convenience costs may also affect the price relationship. It is therefore very difficult to accurately predict fuel prices.

Page 62 of 111 E85 consumption in 2012 and 2013 discussed above, we have considered other source s in developing our estimate of the volume of E85 that could reasonably be consumed

. The following discussion presents the various sources and approaches used to inform our estimate.

To begin with, we considered that even without further reductions in the price of E85 relative to the price of E10, higher E85 consumption in 2014 could reasonably be expected compared to 2012 and 2013 based on business

- as

- usual growth in the number of FFVs in

- use and the number of retail stations offering E85. The combine d effect of these two factors could raise the total E85 consumption volume from our 2013 estimate of about 100 mill gal to about 125 mill gal in 2014 if the purchasing behavior of individual FFV owners remains constant. 56

In the March 2010 RFS final rul e we presented a means for estimating the E85 consumption capacity of FFVs based on historical market practices with diesel fuel. 57 We defined “reasonable access” to E85 as a situation in which one out of every four service stations

to which an FFV owner h a d access offered E85, such that an FFV owner could be considered to have a reasonable option of refueling on E85. All other FFVs would then be assumed not to have reasonable access to E85, and would therefore always refuel on gasoline (here presumed to

b e E10). Following this one

- in

- four access approach, we estimated that approximately 8.6% of FFVs would have access to E85 in 2014 based on projections of the number of retail stations likely to offer E85. Similarly, the total amount of energy 58 consumed b y all FFVs in 2014 would be about 9% of all the energy consumed by all light

- duty vehicles and trucks. If the price of E85 reflected only the energy difference between it and E10, the total volume of E85 consumed under this approach could be about 160 mil l gal. If the price of E85 was lower than this level and as a

result half of all FFV owners with access used E85, the total volume of E85 consumed could reach 640 mill gal. Details of these calculations can be found in a memorandum in the docket. 59

We have also considered other projections of E85 usage, recognizing the varying assumptions made in developing these projections as well as the differing purposes of the projections. For example, in their comments on the NPRM for the 2013 standards, the University of Illinois included an article from the February 13, 2013 issue of Farmdoc Daily in which E85 consumption in 2014 was assumed to be 300 mill gal if E85 prices were sufficiently low in comparison to E10 prices, though they did not quantify the prices needed to reach this E85 consumption level.

Finally, in the context of EPA's response to requests for a waiver of the 2012 renewable fuel volume requirements due to drought, the Department of Energy provided its own analysis of

the maximum volum e of E85 that could be consumed based on a technical analysis of retail station throughput. 60 Based on assumptions about E85 tank sizes at retail stations and the

Page 63 of 111 associated refill frequencies, DOE estimated that the maximum sales of E85 would be 600 mill gal. 61 This DOE analysis focused on the potential throughput at E85 stations given certain underground tank refueling frequencies, and did not consider such things as vehicle refueling frequencies. DOE’s analysis also noted that to achieve its potential, E85 may need to be priced at a greater discount than it would be based on the energy content differential between E85 and gasoline alone to account for the more frequent refueling that E85 requires. We request comment on how DOE's analysis could be refine d to better estimate potential E85 consumption.

c. Proposed Projection of E85 Consumption in 2014

O ur goal for this proposal is to generate a realistic estimate of the amount of E85 that could reasonably be supplied to and consumed in the transportation sector in 2014 in light of the

various circumstances involved with distribution and sale of E85. As with other volumes of renewable fuel, w e believe that it is most appropriate to project a range of E85 volumes that

reflects the volume that could reasonably be consumed in 2014. This projected range for E85 is used to determine a range for the total volume of ethanol that can be consumed, which is further combined with projected ranges for non

- ethanol renewable fuels to determine a range for the

total renewable fuel standard. For the final rule, we will determine a single value within the projected range that is our best estimate of a realistic projection of total renewable fuel in 2014 for purposes of exercising the waiver authority. Once the applicable volume requirements are set, the parties in the market will determine whether our estimated volume of E85 is in fact consumed, or whether other renewable fuels are consumed instead of the volume of ethanol that

we estimate could be consumed as E85.

Based on our analysis of the available information described above, we are estimating a range of 100

- 300 mill gal of E85 consumption for 2014. We believe that this estimated range of E85 encompasses the most likely possibilities. Volumes b elow 100 mill gal are possible, but we believe that they are unlikely given that we expect such volumes to be reached in 2013 and

the market conditions that resulted in these values to continue. Likewise volumes above 300 mill gal are possible, but we bel ieve that they are unlikely. As described above, we believe that 300 mill gal of E85 could be consumed in 2014 if the monthly trends from the first half of 2013 continue unabated through both 2013 and 2014, and further increase due to growth in both retai l stations offering E85 and FFVs in the fleet. E85 consumption above 300 mill gal in 2014 would require that these trends increase even further, and in a sustained fashion, through the end of 2014. Therefore 300 mill gal is the highest value we would con sider at this time as an upper end of the range of possible volumes of E85 for 2014. However, we acknowledge that the volume of E85 sold into the market is likely also a function of the standard for total renewable fuel that we

set . We request comment an d data from the public that would help estimate the impact of lowering the volumetric requirements on the incentive to sell ethanol blends higher than E10.

In light of current uncertainties and the limited information available at this time, we are

pro pos ing that the specific volume of E85 that we would use in determining total ethanol

61 In generating this estimate, DOE assumed that the number of retail stations offering E85 would be about 2,300. We estimate that the number of stations offering E85 will be closer to 3,300 in 2014, which would correspond to a

maxi mum E85 throughput of about 860 mill gal.*** EO12866 Review

Page 64 of 111 consumption for 2014 would be based on the mean value from the Monte Carlo analysis within the range of potential E85 volumes. As explained in Section IV.B.4 below, the Monte Carlo analysis for E85 is based on a half

- normal distribution, consistent with our view that a reasonable level of E85 consumption is more likely to be towards the lower end of the proposed range. Based on this analysis, the mean value for E85 consu mption would be about 1 8 0 mill gal. The mean provides a balance between the projected higher and lower volumes of E85 that could be reasonably achievable. While we believe that volumes of E85 at the high end of our proposed range are achievable and well within the capabilities of the existing vehicle and refueling infrastructure, basing the total renewable fuel volume on E85 volumes at the high end of what is achievable could present an increased risk of non

- compliance for obligated parties if more E85 is called for than was projected in setting the percentage standards. This could occur, for example, if uncertainties in projected gasoline and diesel consumption for 2014 led to a requirement for more than 300 mill gal E85. By using the mean, we would red uce the likelihood of potential

outcomes such as this.

The proposed mean volume of 180 mill gal for E85 is consistent with the recent upward trend in E85 production described above, where E85 is estimated to have been about 70 mill gal

in 2012 and could reach and potentially exceed 100 mill gal in 2013. With regard to 2013, the

increase is also consistent with available state

- specific data on E85 production increases in the first two quarters.

W e request comment more generally on the range of E85 consumption that could reasonably be achieved under appropriate conditions in 2014, including the methodologies and approaches that would provide a projection of E85 that could reasonably be consumed in light of the various factors affecting the distribution and sale of E85 . We reiterate our recogni tion that there is a short time period in which to achieve infrastructural and market changes that would affect E85 consumption in 2014 and that the approach to estimating E85 consumption described above, consistent with best available information, is appr opriate. We request comment in particular on methodologies and approaches that would be appropriate in light of these

considerations

.

d. Estimating Total Ethanol Consumption in 2014

To estimate the total volume of ethanol that could reasonably be consumed in 2014, we assumed that volumes of E0 and E15 would be essentially zero, that E85 consumption would be in the range of 100

- 300 mill gal and contain 74% denatured ethanol, and that all remaining gasoline would be E10 with a denatured ethanol content of 10%. We assumed that the total energy consumption for all gasoline

- powered vehicles and engines would be 14.33 Quadrillion*** EO12866 Review

Page 65 of 111 Btu 62

, and that this amount of total energy consumption i s fixed regardless of the relative amounts of E10 and E85. Based on a denatured ethanol energy content of 77,000 Btu/gal and a gasoline (E0) energy content of 115,000 Btu/gal, we determined that an E85 consumption range

of 100

- 300 mill gal would corresp ond to a total ethanol consumption volume of 12.95

- 13.09 bill gal. This ethanol volume would include non

- advanced ethanol such as that made from corn as well as advanced biofuels such as sugarcane ethanol or other domestically

- produced advanced

ethanol.

2. Estimating Availability of Non

- Ethanol Renewable Fuel Volumes

In addition to the volume of ethanol that could reasonably be consumed in 2014, the total volume of renewable fuel depends on the volume of non

- ethanol renewable fuels that are projec ted to be available in 2014. These include both advanced and non

- advanced non

- ethanol

renewable fuels of all types that could reasonably be supplied to meet all four standards.

a. Non

- Ethanol Cellulosic Biofuel

The production of non

- ethanol cellulosic biofuel in 2014 is projected to be between 0 and

9 million ethanol

- equivalent gallons. This volume could be significantly greater if additional pathways for the generation of cellulosic biofuel RINs are approved and additional volumes of heating oil gene rate cellulosic RINs. For more details on the potential production of non

- ethanol cellulosic biofuels in 2014, and the companies expected to produce these fuels, see Section II.

b. Biomass

- Based Diesel

Obligated parties are required to fulfill a Ren ewable Volume Obligation (RVO) based on a national applicable volume for biomass

- based diesel of 1.28 bill gal of biodiesel (1.92 bill

ethanol

- equivalent gallons) in 2013. 63 As described in Section III, in today's NPRM we are proposing that the national ap plicable volume for biomass

- based diesel remain the same for

2014. However, this proposed requirement is not based exclusively on projected availability and we recognize that greater volumes could be available for purposes of satisfying the advanced

biofu el and total renewable fuel volume requirements.

There is a large amount of excess production capacity for biomass

- based diesel, including at facilities that were in operation in 2012. While the total production capacity for all registered and unreg istered biodiesel facilities is about 3.6 bill gal, the production capacity for only those facilities that produced some volume in 2012 is 2.4 bill gal, and the production capacity for

62 EIA Annual Energy Outlook 2013, Table 37. Represents lower heating value. For determining the total volume of ethanol that can be consumed in 2014, AEO provides 2014 gasoline consumption projections in the re quired energy units. However, EIA's Short

- Term Energy Outlook provides 2014 projections that are more recent, but in

units of volume. EIA’s input to EPA prior to issuance of the final RFS rule for 2014 will be based on the latest

available STEO forecast rather than the AEO2013 or AEO2014 Reference cases.

Distribution of Capacity Utilization for Registered Parties that

Produced Some Biodiesel in 2012

While there is a large amount of excess production capacity, the degree to which it will be used to produce biodiesel in excess of 1.28 bill gal depends on a variety of factors. One of

those factors is the federal tax credit for biodiesel that was most re cently extended through the

end of 2013 under the American Taxpayer Relief Act of 2012 . Under this Act, parties that produce a mixture of biodiesel and diesel fuel can claim a $1.00

- per

- gallon credit against their tax liability

. 65 This tax credit has enab led biodiesel to be more competitive with other advanced biofuels. However, as of this writing it is unclear if this tax credit will apply in 2014. Since many expect the tax credit to have a direct impact on the economic attractiveness of biodiesel,

the fact that it does not yet apply in 2014 adds uncertainty to the volume of biodiesel above 1.28 bill gal that may be produced and consumed in the U.S. As discussed further in Section IV.B.4

- 2 below, we have assumed that the tax subsidy for biodiesel will n ot be extended past 2013. This is reflected in an upper end of the range for biomass

- based diesel no higher than the volume that may be used in 2013, and through the use of a half

- normal distribution in the context of the Monte Carlo process. We request comment on the degree to which the presence of the biodiesel tax credit in 2014 would affect our projections of the volumes that could be reasonably available

in 2014. To the extent we have new information on the status of the tax credit in 2014, EPA will consider that information in the development of the final rule.

According to production data available through EMTS, the total volume of biomass

based diesel produced through August 2013 was 1,053 million gallons. Depending on how

Page 67 of 111 monthly production co ntinues through the remainder of 2013, we would expect total 2013 biodiesel production to be between 1.6 and 1.8 billion gallons. A projection of 1.8 bill gal results from the assumption that the August production rate continues through the rest of 2013. If the trend in production follows the downward trend that occurred in 2012 in the September

- December timeframe (representing, for example, potential seasonality of available feedstocks or demand), the total 2013 production would be 1.6 bill gal.

Figur e IV.B.2.b

- 2 Projected Production of Biomass

- Based Diesel in 2013

These 2013 biodiesel production volumes are occurring in the context of a $1/gal tax credit. While they provide a clear indication of the production capabilities of the industry, they do not provide an accurate indicator of the volumes that would be produced in the absence of the tax

credit.

In the past some stakeholders have expressed concern that there may be limitations i n biodiesel consumption that c ould be imposed by manufacturer w arranties and cold

- weather operation , and that this could impact use of biodiesel above 1.28 bill gal

. However, we do not believe that this is the case for 2014. For instance, most diesel engines are warrantied by their manufacturer to B5. That is, the use of biodiesel in concentrations above 5vol% will void these warranties. While not a legal limitation on the use of biodiesel, it does present a practical limitation. Assuming a total diesel consumption volume of about 56 bill gal for 201 4 66 , B5 for

the diesel pool as a whole would correspond to a biodiesel volume of 2.8 bill gal. However,

s ome diesel truck engines have been warrantied by their manufacturers to consume B20, starting

in 2011. 67 This could potentially raise the limit on biodiesel consumpt ion even higher, assuming

66 EIA Annual Energy Outlook 2013, Table 11.

67 Very few engine models are warrantied by manufacturers to consume B20 have been sold in the U.S. As such,

this volume of biodiesel was assu med to be negligible for purposes of this estimate.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 68 of 111 retailers would dedicate a pump exclusively to B20 for this pool of diesel fuel consumers. Since 2.8 bill gal is significantly higher than the range of biodiesel volumes we are considering in this proposal, manufacturer warrantie s do not represent a limitation on biodiesel use in 2014.

P roduction of biodiesel in 2014 is likely to be impacted significantly by feedstock prices.

S ince their peak in August and September of 2012 during the height of uncertainty about the

effects of the 2012 drought, prices of soybeans and soybean products have been trending

downward

. The USDA World Agricultural Supply and Demand Estimates (WASDE) Report’s

estimate 68 of soybean prices for the 2012/ 20 13 marketing year have declined from an August 2012 range of $15

- 17 per bushel to a June 2013 estimate of $ 14.35 per bushel for the 2012/2013 marketing year. WASDE’s June Outlook Report estimates that for the 2013/2014 marketing year (which includes the months of Octo ber through December 2013) soybean prices will range
from $9.75

– $11.75 per bushel which is in line with the projections used by EPA in the 2013

biomass

- based diesel volume final rule. 69

At the same time, even biodiesel blends as low as B5 cannot be u tilized year

- round due to

cold weather constraints. T he cloud point for B5 soy methyl ester (SME) blended with No. 2 diesel is estimated to be approximately 5 °F . Thus, the use of B5 is highly unlikely in any region where temperatures regularly drop belo w 5 °F . Assuming that biodiesel cannot be blended in such regions during any month where the 10% percentile temperature falls below 5 °F would

result in a reduction of the 2014 biomass

- based diesel volume by only about 3%. This would still permit more th an 2 bill gal of biodiesel to be consumed in 2014. Thus, it appears that for 2014, the ability to consume biodiesel in the vehicle fleet is not constrained by cold weather.

There are a variety of other sources that provide benchmarks for what volumes of biodiesel could be reasonably available in 2014 in excess of 1.28 bill gal. For instance, in the

2013 standards final rule 70 , we assessed potential feedstocks for biodiesel production, concluding

that excess soy oil and corn

- oil could be used to produce a n additional 200 mill gal of biodiesel in 2013 above the 1.28 bill gal requirement. For 2014 the additional biodiesel from these sources could be higher. According to USDA, domestic soybean production is expected to increase by 13% in the 2013 soybean ma rketing year which extends through September 2014, in comparison to the 2012 marketing year. 71 If this occurs, then domestic production of soy oil c ould increase by about 240 mill gal. Regarding corn

- oil, more than one third of the 320 mill gal total prod uction was exported in 2012 . These exports could be diverted to biodiesel production depending on relative prices and other factors. Taken together, the use of both additional soy oil

Page 69 of 111 production and the diversion of corn oil exported could bring the total biodiesel production volume to about 1.62 bill gal.

We continue to receive requests for approval of additional RIN

- generating pathways for new feedstocks to expand the availability of feedstock types and for new production processes to produce biod iesel. 72 While the degree to which these new processes and feedstocks may be viable for the 2014 production year is uncertain, given their directional impacts on lowering cost and improving feedstock availability, we would expect that approval of such new pathways would add biodiesel production volume in 2014. For example, since the adoption of the final rule in March 2010, we have added canola and camelina oil as valid biodiesel feedstocks and analyzed the potential to produce up to 600 million gallons of biodiesel from these new feedstocks by 2022 through expanded crop production. 73 These feedstocks were added in response to industry requests based on their intention to expand production of these feedstocks to support biodiesel production. Since canola a nd camelina are established crops that can be grown for biodiesel use today, some portion of these maximum volumes could be produced in 2014, adding to the volume of feedstock otherwise available for biodiesel production.

We are aware of three other sources that provide potential benchmarks for biodiesel production volume in 2014. In 2011, IHS Global Insight estimated the potential for biodiesel production over the following decade. 74 Under specified assumptions for crude oil price, crop yields, tec hnology, and tax policies, this report concluded that it would be economically feasible to produce 1.54 bill gal biodiesel in the U.S. in calendar year 2014. This estimate assumed that the biodiesel tax credit would be extended beyond 2013, and did not ex amine a case in which the

tax credit is not extended.

In their comments on the NPRM for the 2013 standards, the University of Illinois provided the results of an analysis of both production and consumption limitations for ethanol and biodiesel. They con cluded that 1.7 bill gal of biodiesel could be available without overwhelming feedstock supplies, but provided little detail on the limits of feedstock supply. It also assumed the extension of the biodiesel tax credit. Darling International, Inc. also ev aluated available feedstocks and concluded that 1.9 bill gal of biodiesel could be produced without diverting feedstocks from domestic food requirements. Their analysis

, however, was silent with respect to whether it assumed the extension of the tax cred it.

Finally, we note that there are also international sources of biodiesel that could be imported into the U.S. and which could be eligible to generate either D4 (biomass

- based diesel) or D6 (renewable fuel) RINs in 2014. While there is a significant v olume of biodiesel that is produced around the globe, it is unclear how much could potentially be imported into the U.S. in 2014 and accordingly we have not included these sources in our analysis of available supply.

72 For example, as of June 2013, EPA had 5 petitions for new biodiesel pathways under review and had approved 3 additional petitions for new biodiesel pathways.

73 See for example the final rules adding giant reed and napier grass feedstocks (74 FR 41703) a nd final rule adding camelina and energy cane as feedstocks and renewable gasoline and renewable gasoline pathways (74 FR 14190)

Page 70 of 111 Based on the discussion above, we hav e good reason to believe that the volume of biodiesel that can be produced in 2014 will be higher than the applicable volume requirement of 1.28 bill gal. A summary of all of the sources we have considered is provided below.

Table IV.B.2.b

U niversity of I llinois estimate in their comments 1,700 Darling International, Inc. estimate in their comments 1,900

Production capacity of a ll registered biodiesel facilities that produced some biodiesel in 2012 2,400

As with E85, we believe that it would be most appropriate to project a range of possible biodiesel production volumes for 2014, using the values in Table IV.B.2.b

- 1 as a guide. As explained above, the volumes in the table above represent potential technic al availability

. We recognize that multiple factors would ultimately influence actual production volumes. For the purposes of this NPRM, we are estimating a range of 1.28

- 1.6 bill gal of biodiesel production

for 2014. While it would not be below 1.28 bill gal, as that is the required volume, it could be above the high end of 1.6 bill gal. However we estimate that it would be unlikely to be above this value, especially if the federal tax credit is not extended beyond 2013. For instance, the 1.9 bill g al estimate from Darling international, Inc. was based on extrapolating the historically high production rate from December 2011 into the future. The circumstances in December 2011 were unique: the tax credit for biodiesel was to expire at the end of that month, prompting a jump in production. Thus while it is possible that the production rate from December 2011 might be sustained in the future, we believe it is unlikely if the biodiesel tax credit is not extended past 2013. Likewise the analysis provide d by the University of Illinois which projected 1.7 bill gal biodiesel in 2014 assumed that the tax credit would be extended beyond 2013. A 2011 report prepared on behalf of the National Biodiesel Board indicated that the expiration of the tax credit

at t he end of 2010 caused a substantial reduction in biodiesel production in 2011 compared to

2010. 75

For the purposes of this NPRM, we have assumed that the biodiesel tax credit will not be extended beyond 2013. As a result, we believe that biodiesel produc tion volumes in 2014 are more likely to be towards the lower end of our proposed range of 1.28

- 1.6 bill gal. To reflect this assumption, we have used a half

- normal distribution to represent biomass

- based diesel in the

In order to estimate a range of possible volumes of other non

EPA's Landfill Methane Outreach Program , about 360 mill ethanol

is about 420 mill ethanol

- equivalent gallons 78 . While establishing contracts to ensure that all

CNG vehicles are fueled with landfill biogas rather than fossil

- based natural gas is highly unlikely to occur in the short term given the rapid expansion underway of CNG vehicles in the marketplace, we believe it is reasonable that some smaller portion of all CNG vehicles could be fueled with landfill biogas in 2014. Since the 45.8 mill ethanol

- equivalent gallons of biogas from the Production Outlook Reports, shown in Table IV.B.2.c

- 2, represents about 11% of the annual CNG vehicle consumption, it is reasonab le to expect that this volume could be used in 2014 to fuel CNG vehicles and thus generate advanced biofuel RINs. We request comment, however, on whether this level of consumption can reasonably be achieved within the relevant

time frame.

Therefore, bas ed on the actual production in 2012 and the projected production for 2014, for this NPRM we have used a range of 24

- 132 mill gal to represent non

- ethanol advanced biofuel with a D code of 5. While the actual volume could be above 132 mill gal, we believ e this is unlikely as this volume is based on the projections made by the producers themselves in light of their assessment of their own capabilities and plans. Likewise, while the actual volume could be below 24 mill gal, we believe this is unlikely sinc e the industry has demonstrated that it can produce at this level. For the final rule we will update this range based on more recent data on actual production in 2013 and more recent versions of the Production Outlook Reports.

d. Non

- Ethanol Non

- Advanc ed Renewable Fuel

To determine a range for the non

- ethanol non

- advanced renewable fuel volume, we used the same approach as for the non

- ethanol advanced biofuel volume. That is, we used actual 2012 production to represent the low end of the range and 20 14 projections from Production Outlook Reports to represent the high end of the range. This approach resulted in a range of 1

- 25 mill gal, mostly representing production of biodiesel at facilities that have been grandfathered under §80.1403 and which ma y use feedstocks for which there is currently no valid RIN

- generating pathway, such as sunflower or cottonseed oil. For the final rule we will update this range based on more recent data on actual production in 2013 and more recent versions of the Product ion Outlook Reports.

3. Treatment of Carryover RINs in 2014

In the final rule establishing the applicable standards for 2013, we estimated the volume of ethanol that would need to be consumed to meet the statutory volume requirements prior to

consider ation of RINs carried over from 2012 in 2013. 79 The total estimated volume of ethanol was 14.5 bill gal. I f no ethanol blends higher than E10 were consumed in 2013, the total volume of E10 would be 131.1 bill gal (ignoring small amounts of E0) and the max imum volume of ethanol that could be consumed would thus be 13.1 bill gal. On the basis of these estimates, the

Page 73 of 111 volume of ethanol that is estimated to exceed the amount that could be consumed as E10 in 2013 was 1.4 bill gal.

In addition to the option of using E85 and/or more non

- ethanol renewable fuels, the 2013 standards final rule also pointed to the substantial number of RINs carried over from 2012 into 2013 that could be used in lieu of physical volumes. We determined that there would be about

2.6 b illion such carryover RINs available in 2013. If the 1.4 bill gal of ethanol that is in excess of that which can be consumed as E10 in 2013 is covered entirely by carryover RINs, then there

would still be at least 1.2 billion RINs that could be carried ov er from 2013 and available for use

in 2014.

As described in the 2007 rulemaking establishing the RFS program 80 , carryover RINs are intended to provide flexibility in the face of a variety of circumstances that could limit the availability of RINs. More specifically, carryover RINs provide a mechanism for offsetting the negative effects of fluctuations in either supply of or demand for renewable fuels. The flexibility afforded by these carryover RINs was evidenced in the recent response of the market to the drought in 2012. The flexibility of these carryover RINs is also what we highlighted in the 2013 standards final rulemaking as providing the opportunity for compliance despite potential constraints on physical ethanol consumption.

In the context of determining the appropriate volume requirements for 2014, as for 2013 it would be appropriate to consider carryover RINs that may be available. However, we believe it is also important to the viability of the market that some reasonable amount of carryov er RINs continue to be available. Carryover RINs act as a buffer, and allow the regulated parties to address unforeseen circumstances that could limit the availability of RINs, and to address renewable fuel supply circumstances that differ from those assu med in the process of generating the projected volume ranges discussed above. The provision for carryover RINs recognizes that Congress structured the RFS program to provide a degree of flexibility for the obligated parties. In 2013 preserving such a buf fer was not a concern, since even if the 1.4 bill gal of ethanol that is estimated to be in excess of that which can be consumed as E10 in 2013 is covered entirely by carryover RINs, there would remain at least 1.2 billion additional, unused carryover RINs . For 2014, however, if we accounted for all 1.2 billion carryover RINs in setting the applicable standards, obligated parties would be left with no flexibility for addressing other unforeseen

circumstances. We believe that a standard

- setting process tha t included an assumption that the carryover RIN balance would be reduced to zero would be contrary to the original intention of the provision for providing a degree of flexibility through carryover RINs. For this reason, we have not accounted for carryove r RINs in our assessment of the reductions in the statutory volume requirements that would be appropriate in setting the RFS standards for 2014. For years after 2014, if circumstances differ substantially from those described here, we may again

consider t he existence of carryover RINs in the standard

- setting process depending on the number of carryover RINs expected to be available and projections of supply and consumption of renewable fuels. We request comment on whether and how to account for carryover RINs in setting the standards.

Page 74 of 111 4. Proposed Range for the Volume Requirement for Total Renewable Fuel

As discussed in the preceding sections, we have estimated volume ranges for five different categories of renewable fuel as a step towards estimating t he volume requirement for total renewable fuel for 2014. These ranges are summarized below.

Table IV.B.4

- 132

Available volumes of non

- advanced renewable fuel 1

- 25

a Represents a physical volume range of 1.28

- 1.6 bill gal

By aggregating these five categories, we can estimate the total volume of renewable fuel that represents both the volume of ethanol that could reasonably be consumed as E10 and higher ethanol blends, and the volume of all non

- ethanol renewable fuels that could reasonably be available to meet the four applicable standards. We note that in practice these five categories are not independent from one another, since different types of renewable fuel will differ in terms of their cost and higher volumes of one type of renewable fuel will reduce the need for volumes from another category in the context of meeting the applicable volume requirements. However, since the ranges shown above are intended to encompass reasonably achievable volumes for each type of rene wable fuel, we believe that they can be treated as independent for the purposes of the aggregation described below.

In order to aggregate the ranges in Table IV.B.4

- 1 into a single range for total renewable fuel, we used a Monte Carlo analysis to accou nt for the need to aggregate multiple ranges, each having different likely distributions of likelihood across their range. As discussed in the preceding sections, the high and the low end of each range represents values such that it is possible but unlike ly that volumes would be outside of those ranges. We have therefore treated these individual ranges as representing the 90% confidence interval of a distribution of possible volumes. In other words, the low end of the range would represent the 5th percen tile and the high end of the range would represent the 95th percentile. This approach is consistent with our judgment that, while the ranges shown in Table IV.B.4

- 1 are intended to encompass the vast majority of possible volumes, there remains a small pos sibility that volumes outside of those ranges are possible. We believe it is reasonable to treat these ranges as representing 90% confidence intervals for purposes of the Monte Carlo analysis, though we request comment on treating them as a different conf idence interval such as 80% or 95%.

As an alternative to a Monte Carlo process for aggregating the volumes in Table IV.B.4

- 1, we could use a simple summation of the ranges (i.e. basing the low end of the range of total

renewable fuel on the sum of the lo w ends of the ranges for each of the five different categories, and likewise for the high end of the range). However, we do not believe that such an approach*** EO12866 Review

Page 75 of 111 would be appropriate. Doing so would tend to exaggerate the width of the range for the required volume of total renewable fuel as it is highly unlikely that 2014 volumes for each of these categories will simultaneously be at the extreme low or high end of the proposed ranges, and would also mischaracterize biofuel categories wherein one end of the ra nge is expected to be more likely than the other. Nevertheless, we request comment on this or alternative methods to the Monte Carlo approach for aggregating the volumes shown in Table IV.B.4

- 1.

For the purposes of the Monte Carlo analysis, we are also proposing an appropriate shape to represent the applicable distribution of volumes within each range. The shape of the distribution of volumes is based on factors unique to each source of renewable fuel. We

identified three standardized distributions tha t we can use to reasonably represent uncertainty in

the distribution of volumes for each of the sources of renewable fuel under consideration.

Figure IV.B.4

- 1 Standardized Distributions Used to Aggregate Ranges a

a The skewed distribution is based on a W eibull distribution with a shape parameter of 0.5 and a scale parameter of 1.7

.

These three standardized distributions provide a mechanism for representing the regions within each projected volume range where the greatest likelihood of reasonably achievab le volumes may lie, based on considerations of the various sources of uncertainty unique to each source of renewable fuel. We recognize that the half

- normal distribution would by definition include a mode of zero, and that this would imply that the greate st likelihood of occurrence is at the low end of the range. For sources of renewable fuel wherein the low end of the range is estimated to be zero, for instance for some cellulosic biofuel facilities as discussed in Section II.C, the use of

the half

- norma l would appear to suggest that zero is the most likely result. However, in the context of the Monte Carlo process for combining volume ranges from different sources, we are proposing to use the mean rather than the mode as described more fully below. Nev ertheless, other distributions might be reasonable to address concerns about the mode in the half

- normal distribution. For instance, a gamma distribution could be used, or a Weibull distribution with*** EO12866 Review

Page 76 of 111 greater skewness than that shown in the figure above. We request comment on the use of these

alternative distributions.

In the case of biomass

- based diesel, we are proposing that the applicable volume requirement for 2014 would be 1.28 bill gal. Since this volume would be required, there is no realistic li kelihood that the actual volume will be below 1.28 bill gal. While production volumes

of biomass

- based diesel in 2013 are expected to substantially exceed the required volume of 1.28 bill gal, this is likely driven in large part by the tax credit for biod iesel, currently scheduled to expire at the end of the year, on the price of D6 RINs which have increased since the beginning of 2013, and potentially other factors as well. Without the tax credit in place, demand for biodiesel substantially beyond the re quired volume is uncertain. Under the assumption that the biodiesel tax credit will not be extended beyond 2013, we believe that a ny additional incremental volumes above 1.28 bill gal would be progressively less likely than the required volume. This

sugg ests that a half

- normal distribution would be the most appropriate way to represent volumes

of biomass

- based diesel. With regard to non

- ethanol cellulosic biofuel, we developed a distribution that was based on an aggregation of projected volume ranges for each cellulosic biofuel facility. See Section II.C for more discussion. For the total volume of ethanol that could reasonably be consumed, we chose a half

- normal distribution representing ethanol in E10 and

E85 because there is little historical informa tion on how market prices for E85 might respond to higher RIN prices, nor on how FFV owners might respond to changes in the relative price of E85 and E10. In the future it may be more appropriate to use a skewed or normal distribution for the

total volume of ethanol to reflect a growing understanding of the impact that RIN prices have on the retail price of E85 and the impact that E85 prices have on consumer choice. For volumes of

non

- ethanol advanced biofuel and non

- ethanol non

- advanced renewable fuel, w e chose normal distributions because we believe there is an equal likelihood that the volumes that could be made available would be on either the low end of the respective ranges or the high end of the respective ranges. We do not believe that actual hist orical volumes, which form the basis for the low end of the range in both cases, should also be used as justification for using skewed distributions. The distributions that we used for each of the five categories of renewable fuel are

shown below.

Based on the estimated ranges and distributions, we used a Monte Carlo process to aggregate the five distributions into a single distribution representing total renewab le fuel. The Monte Carlo process randomly samples each of the five distributions in an iterative fashion. The results of all the iterations were then summed to produce a distribution for total renewable fuel.*** EO12866 Review

Results of Monte Carlo Simulation for Total Renewable Fuel

We recognize that the Monte Carlo process is an approximation to the mathematical formula that would result if the probability density functions for each of the distributions shown in Figure

IV.B.4

- 1 were combined mathematically using convolution. However , we believe that the additional complexity of such a process is not warranted given the uncertainty inherent in the volumes ranges and the assigned distributions. The Monte Carlo process for combining distributions provides a reasonably accurate result w ith a considerably simpler process.

Based on this approach to aggregating the five ranges shown in Table IV.B.4

- 1, the volume of total renewable fuel that we are proposing for 2014 would fall within the range of

15.00

- 15.52 bill gal. 82 Given that the applicable volume in the statute is 18.15 bill gal, this range represents a reduction of 2.63

- 3.15 bill gal. Within the uncertainties discussed above for each of the components, a range of 15.00

- 15.52 bill gal represents a volume of renewable fuel

th at reasonably accounts for both limitations in the volume of ethanol that can be supplied and consumed as well as limitations in the availability of non

- ethanol renewable fuels.

82 The numbers are expressed as two significant digits to reflect that the applicable volu mes in the statute are expressed this way.*** EO12866 Review

Page 79 of 111 The distribution generated by the Monte Carlo process also provides a basi s for determining a specific value within the range. We do not believe that using either the low end or high end of the proposed range would be appropriate as the basis for the applicable standard. While we believe that the upper end of the projected ran ge is achievable, basing the total renewable fuel volume on this higher value could present an increased risk to obligated parties if, for example, uncertainties in projected gasoline and diesel consumption for 2014 lead to a requirement for more renewable fuel than is available or can be consumed. A value between the low and high ends, in contrast, would better account for cases in which the actual values for some of the input volumes fall at the high end of their respective ranges while the actual value of other input volumes fall at the low end of their ranges. Options for a value falling between the low and high ends of the range include the mean, the mode (highest frequency value) and the median (50th percentile). It may also be reasonable to use a v alue representing higher or lower values in the distribution, such as the 25th or 75th percentile. The table below shows the values for each of these approaches that correspond to the distribution in Figure IV.B.4

- 2.

In today's NPRM, we are proposing to use the mean value for the volume requirement for total

renewable fuel

, which represents our best estimate of the average amount of renewable fuel volumes that could reasonably be supplied . However, we request comment on whether it would be more appropriate to utilize either the mode or median (50 th percentile ), or some other value in the appropriate range shown in Table IV.B.4

- 3 that best reflects renewable fuel volumes that

could reasonably be supplied under this program

.

As discussed throughout this section, there is considerable uncertainty in the estimates of

some of the various components from which the required volume for total renewable fuel has

been derived . There are many factors affecting supply, and they could lead to greater or lesser supply of renewable fuels than projected, such as higher or lower volumes of non

- ethanol renewable fuel or advanced biofuels, higher or lower volumes of E85, the degree to which E0 is

used , if any, and so on. Obligated parties also have significant flexibility to address compliance through a number of various approaches

, such as the ability to use carryover RINs generated in

2013 , or to carry a compliance deficit into 2015. Our proposed approach for dealing with this uncertainty has been to develop ranges for the various components and utilize the Monte Carlo process for aggregating the components into a single range and mean value. These estimates will

be refined for the final rule base d on more up

- to

- date information and any new information received through the public comment process. We have used this approach to develop the best available volume projections using current information.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 8 0 of 111 We understand that values lower or higher than the mean also could be used. For example, some parties may believe that a value lower than the mean should be used to provide greater confidence in the adequacy of supply, and avoid the risks associated with a volume

reduction that is not sufficient to address the supply problems. From the perspective of production and use of renewable biofuels, in contrast, a higher value than the mean would avoid the risks associated with a volume reduction that is more than what is necessary to address the supply problems. As noted, our current view is that the best approach for resolving this uncertainty is to neither underestimate nor overestimate the market’s capacity to supply and

consume renewable fuels. We request comment on our proposed approach and alternate approaches described here.

C. Determination of Reductions in Advanced Biofuel

The second step in our proposed framework for setting the applicable volume standards would be to determine an appropriate reduction in advanced biofuel that a ccounts for the availability of advanced biofuels in light of the significant shortfall in cellulosic biofuel compared to the statutory volume, as well as t he contribution of ethanol in this category to the supply concerns related to total renewable fuel. The proposed volume of advanced biofuel should also support the goals of the RFS program for continued growth in the advanced biofuel category as reflected in the increasing gap between the cellulosic biofuel and advanced biofuel volumes set by EISA

.

1

. Available Volumes of Advanced Biofuel in 201 4

Using a process similar to that for total renewable fuel in Section IV.B above, we

determined the maximum volume of advanced biofuel that can reasonably be available in 2014.

This volume defines the uppe r limit for any potential volume requirement we would set for advanced biofuels under the overall approach we are proposing . As described more fully in Section IV.A above, availability is one important factor to consider it determining the appropriate vol ume of advanced biofuel to require. However, as discussed in Section IV.C.2 below, for 2014 additional considerations lead us to propose to set the advanced biofuel volume requirement at a level below the total available volume.

In this section we descr ibe the estimation of reasonable ranges for four separate categories of advanced biofuel, including:

• Cellulosic biofuel

• Biomass

- based diesel

• Domestic Production of Other Advanced Biofuel

• Imported Sugarcane Ethanol

a. Cellulosic biofuel*** EO12866 Review

Page 81 of 111 As discussed in Section II above, the production of cellulosic biofuel in 2014 is projected

to be between 8 and 30 million ethanol

- equivalent gallons. This range can be separated into

ethanol and non

- ethanol components as shown below.

The projected volume could be significantly greater if pathways for the generation of cellulosic

biofuel RINs from land fill biogas and corn kernel fiber are approved and additional volumes of cellulosic heating oil are produced. For more details on the potential production of non

- ethanol cellulosic biofuels in 2014, and the companies expected to produce these fuels, see S ection II.

b. Biomass

- Based Diesel

The range of biomass

- based diesel that we used in estimating the availability of advanced biofuel is the same as the range that we used in determining the proposed volume of total

renewable fuel. Table IV.B.2.b

- 1 lists the sources that we used to conclude that there could be

1.28

- 1.6 bill gal of biodiesel production in 2014.

c

. Domestic Production of Other Advanced Biofuel

In Section IV.B.2.c above we used 2012 production data and Production Outlook Reports to develop a range of 24

- 132 mill gal representing non

- ethanol advanced biofuel with a D code of 5. These same sources were used to develop a range of ethanol advanced biofuel with a D

code of 5.

In 2012, 28 mill gal of ethanol advanced biofuel (other than cellulosic ethanol) was produced i n the U.S. Based on Production Outlook Reports, we project that domestic production

of such biofuel using some combination of sugarcane, grain sorghum, and separated food wastes could be as high as 142 mill gal. Based on these sources, for this NPRM we h ave used a range

of 28

- 142 mill gal to represent domestic production of ethanol advanced biofuel with a D code

of 5.

d

. Imported Sugarcane Ethanol

Sugarcane ethanol qualifies as advanced biofuel, and historically the U.S. has imported

substantial vo lumes of it. Imports from the last ten years are shown below. While ethanol imported into the US is not produced exclusively from sugarcane, it has historically been the*** EO12866 Review

Page 82 of 111 primary feedstock for ethanol imported into the U.S. and is expected to continue to be the primary feedstock of ethanol imported into the U.S. in future years. While the generation of advanced biofuel RINs from sugarcane ethanol is not limited to ethanol imported from Brazil, historically Brazil has been the source of the majority of eth anol imported into the United States. As such, this section focuses on the availability of sugarcane ethanol imported from Brazil.

Figure IV.C.1.d

- 1 Historical Imports of Ethanol into the U.S.

Source: EIA, "U.S. Imports by Country of Origin

. "

As som e stakeholders have noted before, imported volumes of ethanol have been highly variable. As a commodity traded on the world market, the market clearing price and quantity of Brazilian ethanol sold into the U.S. market fluctuates over time. Significant fac tors that can affect the price and quantity of ethanol imported into the U.S. include:

• Sugarcane harvest (both acres planted and yield)

• Worldwide market for sugar

• Worldwide demand for sugarcane ethanol

• Brazilian demand for ethanol, including the minimum ethanol content of gasoline as specified by the Brazilian government

• Potential for exporting corn

- ethanol from the U.S. to Brazil

• Opportunities for sale of sugarcane ethanol in the U.S. which is a function of the RIN price for advanced biofuel, legal and practical constraints on the volume of ethanol

that can be consumed , state Low Carbon Fuel Standards (LCFS) program demand, and the availability and price of competing advanced biofuels such as biodiesel

• Import and export tariffs*** EO12866 Review

Page 83 of 111 P roduction o f sugarcane in Brazil in recent years has been lower than normally expected due to two factors. First, adverse weather conditions reduced production. 83 For example, adverse weather conditions are estimated to have reduced cane production by about 4% in the 2011/2012 marketing year. 84 Thus, a return to more typical weather conditions

, such as occurred in the 2012/2013 agricultural marketing year, in the timeframe that this rulemaking considers would by itself restore approximately 4% of production. Second, the general global economic downturn in recent years made obtaining credit more difficult in the Brazilian sugar cane industry, resulting in delayed r eplanting of existing fields. Normally sugarcane fields are replanted every five or six years to maximize yield. However, the lack of available credit caused some growers to delay the expense of this replanting, resulting in older fields losing productio n. 85 It appears that credit conditions have eased and that more direct investment in sugar cane production and milling in Brazil is occurring.

Some parties expected a more typical trend in sugarcane ethanol production for the

2012/2013 through the 201 4 /2 01 5 harvest years

, with replanted fields boost ing sugarcane production in existing plantations and, in response to increased worldwide demand, a growth in the acres planted with sugarcane. Increased production is supported by the Brazilian government

whic h announced in February 2012 support for a plan to invest over $8 billion annually to boost cane and ethanol production. 86 Private investment in Brazil may also be increasing. For example, Usina de Acucar Santa Terezinha, a Brazilian ethanol producer, las t year announced plans to invest almost $300 million in a new mill and sugarcane plantation. 87 Such information

suggests that sugarcane and ethanol production in the 2013/14 and 2014/15 harvest year s could be higher than production in 2011 and 2012

.

Braz il’s sugarcane ethanol production serves both its domestic market as well as the export market. The government of Brazil sets a minimum ethanol concentration for its gasoline. In 2011, the Brazilian government lowered this concentration to 20%, reflectin g in part the decrease in domestic ethanol production. However, given the more optimistic production outlook, Brazil raised the minimum ethanol concentration to 25% effective May 1, 2013. 88 The 25% concentration rate is the highest allowed by law in Brazi l. The ability of the Brazilian government to reset the minimum ethanol content introduces some uncertainty in projecting future Brazilian demand. However, historically, adjustments have been infrequent, relatively small in degree (a few percent), and lar gely influenced by the price of ethanol (high prices leading to a reduction in the minimum). Indeed, as evidenced by the reduction to a 20%

84 The sugar marketing year in Brazil’s center

- producing region, where the large majority of production occurs, runs from May thro ugh April.

85 On the margin, the high sugar prices may have also encouraged some growers to divert their crop from ethanol production to sugar production. But most cane growers do not have this flexibility with sugarcane mills designed

for fixed amounts of refined sugar or ethanol so high sugar prices was likely a contributing factor but not a major cause of reduced sugarcane ethanol production in Brazil.

Page 84 of 111 blending rate in 2011, the Brazilian government considers the likely supply of sugarcane ethanol to support its dom estic needs in setting the minimum ethanol content of its blended fuel.

The Iowa State/CARD model projects that Brazil will produce roughly 8.7 bill gal of

ethanol in 2014. Non

- fuel use and Brazilian ethanol exports to countries other than the U.S. is

e stimated to be around 500 million gallons, which leaves roughly 8.2 bill gal for Brazilian consumption and for exports to the U.S. If the minimum blending rate for ethanol in motor vehicles in Brazil is set at 25% (the current rate), Iowa State estimates that Brazil will consume roughly 5.9 bill gal of ethanol. At a 20% minimum blend rate, ethanol demand i n Brazil would be roughly 5.2 bill gal. Therefore, even with the 25% minimum blending requirement for ethanol in vehicles, Brazil should have up to 2.8 bill gal available for a wide variety of domestic uses as well as the potential to export ethanol to the U.S. 89 Thus, assuming that the 25% blending rate remains in effect through 2014 (including both the 2013/14 sugarcane season which ends in May 2014 an d the subsequent 2014/15 sugarcane season), the analyses referenced below suggest that more than enough ethanol should be available assuming normal weather patterns to support both the Brazilian domestic demand as well as export to the U.S. in 2014.

The historical volumes of sugarcane ethanol imports into the U.S. from Brazil are indicative of Brazilian production and export capacity, and thus provide several benchmarks for the volume that could potentially be imported into the U.S. in 2014. For instance , the average import volume over the last ten years is 223 mill gal, while the maximum volume was 560 mill gal in 2006. In 2010 Brazil had its largest ethanol production volume in recent history, and in that same year it exported 490 mill gal to the U.S. Finally, the largest total export volume from Brazil to all other countries was 1.35 bill gal in 2008.

There are several other sources providing estimates of what import volumes of Brazilian sugarcane ethanol may be possible in 2014. In an addendum to its Annual Energy Outlook 2013, EIA included an estimate of sugarcane ethanol imports of 719 mill gal for 2014. 90 In their comments on the 2013 standards NPRM, the Brazilian Ministry of Mines and Energy indicated that Brazil could achieve exports of 800 mi ll gal to the U.S. in 2014. A recent report from Iowa State University indicated that total ethanol imports could be 310

- 820 mill gal in 2014, depending on whether the biodiesel tax credit remains in effect. 91

The Food and Agricultural Policy Researc h Institute (FAPRI) publishes several different documents that also provide some benchmarks. The 2012 World Agricultural Outlook projected that total net exports of ethanol from Brazil could be 1,259 mill gal in 2014, 92 while their Biofuel Baseline project s that total ethanol imports into the U.S. could reach 496 mill gal in 2014. 93

Page 85 of 111 Based on the discussion above, we have compiled a list of benchmarks that we believe can be used to estimate a range of import volumes for Brazilian sugarcane ethanol.

Historical maximum ethanol exported from Brazil (2008) 1,350

For the purposes of this NPRM, we estimate, based on a review of the benchmarks shown in the table above, that a range of 300

- 800 mill gal of Brazilian sugarcane ethanol could be available for import to the U.S. in 2014. We do not believe that it would be appropriate to use

either the h ighest or lowest values in the table since they are unlikely to reasonably represent the

market circumstances in 2014.

While the volumes of sugarcane ethanol imported into the U.S. in 2012 were about 500 mill gal, and in 2013 could reach a similar level, we believe it is reasonable to use 300 mill gal as the low end of the range for 2014. There has been significant variability in sugarcane ethanol imports in the past, so volumes below 500 mill gal are possible depending on market factors and relevant pub lic policies in both countries

. W hile volumes above 800 mill gal are possible, we believe that they are unlikely given that the Brazilian agency responsible for projections of exports indicated that 800 mill gal would be achievable in 2014, and 800 mill g al would be a substantially higher import volume of Brazilian sugarcane ethanol than in any previous year.

We have used a projected range of 300

- 800 mill gal for imported sugarcane ethanol in

our estimate of the total volume of advanced biofuel that could be available in 2014. However, as described in Section IV.C.2 below, we are not proposing to use only availability in the determination of the applicable volume requirement for advanced biofuel. Thus the proposed volume requirement for advanced bio fuel would not require the use of 300

- 800 mill gal of sugarcane ethanol, and the actual volume of sugarcane ethanol that is imported will be highly dependent upon competition in the U.S. market with other advanced biofuels that could be

available.*** EO12866 Review

Page 86 of 111 e. Summary

As discussed in the preceding sections, we have estimated volume ranges for six different categories of advanced biofuel as a step towards estimating the availability of advanced biofuel

for 2014. We also identified which of the three standardized curves shown in Figure IV.B.4

- 1 would be most appropriate for each category. A discussion of the standardized distributions for cellulosic biofuel, biomass

- based diesel, and domestic non

- ethanol advanced biofuel are provided in Section IV.B.4 above. For volumes of ethanol advanced biofuel, we chose a normal distribution because we believe there is an equal likelihood that the volumes that could be made available would be on either the low end of the range or the high end of the range. A norm al distribution for ethanol advanced biofuel is also consistent with our approach to non

- ethanol advanced biofuel, as both ranges were developed from the same sources. For volumes of imported sugarcane ethanol, the most recent historical data on actual im ports suggests that the middle of the range 300

- 800 mill gal is likely, and this suggests that a normal distribution is more reasonable than a skewed distribution. The advanced biofuel ranges and the assumed

standardized distributions are summarized bel ow.

As for the total renewable fuel volume, the high and the low end of each range represents values such that it is possible but unlikely that volumes would be higher or lower than this range. EPA therefore treated each individual range in Table IV.C.1.e

- 1 as representing the 90% confidence interval of the applicable standardized distribution. We then used a Monte Carlo process in which each of the six distributions were randomly sampled in an iterative fashion.

The results of all the iterations were the n summed to produce a distribution for advanced. The figure below shows the resulting distribution after 3000 iterations.*** EO12866 Review

- 1 Results of Monte Carlo Simulation for Advanced Biofuel Availability

Based on this approach to aggregating the six ranges shown in Table IV.C.1.e

- 1, we believe that available volumes of advanced biofuel are likely to fall within the range of 2.49

- 3.23 bill gal. Given that the volume requirement in the statute is 3.75 bill gal, this range of availability represen ts a reduction of 0.52

- 1.26 bill gal.

2. Options for Determining Appropriate Reductions in Advanced Biofuel

While projected availability defines the upper limit of the volume requirement we would set for advanced biofuel, we have also considered t wo other factors: the contribution of ethanol in the advanced category to the supply concerns discussed above with respect to total renewable fuel, and the RFS program's goal of growth in the advanced biofuel category. Below we discuss three approaches th at could be taken to determine an appropriate volume of advanced biofuel for 2014. We believe that Option 3 best addresses the dual concerns of constraints on ethanol supply and consumption and limited availability of advanced biofuels while also effectua ting Congress’s intention that the volume require ment for advanced biofuel continues to grow.

a. Option 1: Advanced Biofuel Availability

The RFS volume requirements that Congress established in CAA 211(o)(2)(B) increase steadily between 2009 and 2022. Over this period, the amount of total renewable fuel which is not advanced biofuel (largely corn starch based ethanol) was intended by Congress to grow slowly up to 15.0 bill gal in 2015, and then stay at that level for subsequent years. Cellulosic

biof uel was intended to grow very dramatically, from 0.5 bill gal in 2012 to 16.0 bill gal in 2022.

Non

- cellulosic advanced biofuel was expected to grow steadily every year, increasing from 1.5 bill gal in 2012 to 5.0 bill gal in 2022. This anticipated grow th of the advanced biofuel category*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 88 of 111 is also evident from its increasing role as a component of the applicable volume of total renewable fuel, growing from 5.4% in 2009, to 20.7% in 2014, and 61.1% in 2022. Advanced

biofuel must meet a GHG reduction thresh old of 50%, compared to a 20% threshold for non

advanced renewable fuel. 94 Thus , increased substitution of advanced biofuels for fossil fuels

would result in lower lifecycle GHG emissions from transportation fuels.

In previous rulemakings where we cons idered reductions in the applicable annual volume of advanced biofuel following a reduction in the statutory volume for cellulosic biofuel, we focused on the availability of advanced biofuel (and in some cases available carryover RINs) when making determin ations as to whether a reduction in advanced biofuel volumes was warranted. Using availability to set the applicable volume of advanced biofuel for 2014 and beyond would be consistent with past practice, and would reflect placing sole emphasis on its

avai lability and the growth in advanced biofuels that results. However, the approach we used in previous annual rulemakings was based on the circumstances in previous years. In particular, supply concerns related to the legal constraints on the amount of eth anol that can be blended into gasoline and practical constraints on the volume of ethanol that can be consumed were not a limiting factor in previous years and so were not discussed as a potential basis for determining

volumes. As discussed in Section IV. B.1 above, constraints on ethanol consumption are a limiting factor in 2014.

Moreover, using availability as the sole basis for determining advanced biofuel volumes would ignore the impact that ethanol within the advanced biofuel category have on the s upply concerns related to constraints on ethanol consumption in blends higher than E10. W hile the available volume of advanced biofuel would be predominantly non

- ethanol, a substantial volume

would be ethanol. 95 For an advanced biofuel availability of 2.4 9

- 3.23 bill gal (see Figure

IV.C.1.e

- 1), the fraction that is ethanol ranges from an average of about 18% at the low end of the range to an average of about 25% at the high end of the range. Since any advanced biofuel

that is ethanol contributes to the concerns related to total ethanol consumption, it is appropriate to consider reductions in the required volume of advanced biofuel beyond the 0.52

- 1.26 bill gal reduction needed to ensure that the volume required is available.

For these reasons, we invite comment on the Option 1 approach but are not proposing it.

b. Option 2: Full Reduction in Cellulosic Biofuel

Under the cellulosic waiver authority we have the discretion to reduce advanced biofuel by up to the same amount that we reduce cellul osic biofuel. Thus, a second option would be to reduce the advanced biofuel volume by the same amount that we reduce the cellulosic biofuel volume. Our proposed cellulosic biofuel volume requirement of 8

- 30 mill gal for 2014 corresponds to a reduction of 1,720

- 1,742 mill gal in comparison to the statutory volume of 1,750 mill gal. This is approximately twice the size of the reduction in advanced biofuel that

94 Renewable fuels grandfathered under the provisions of §80.1403 are not required to meet any GHG threshold.

95 While production volumes of ethanol that can qualify as an advanced biofuel, both domestically and internationally are significant, consumption of this fuel will be constrained*** EO12866 Review

Page 89 of 111 would result from accounting for availability alone, as in Option 1, and would result in an

a dvanced biofuel volume requirement of 2,0 08

- 2,0 30 mill gal.

A reduction of 1,7 20

- 1,7 42 mill gal in the advanced biofuel requirement would allow

for overall growth in non

- cellulosic advanced biofuel , consistent with overall levels of non

cellulosic advanced biofuels that Congress specified for 2014 in 211(o)(2)(B). The table below shows that this approach would ensure that the required volume of non

- cellulosic advanced

biofuel

- comprised of biomass

- based diesel and other advanced biofuel

- that wou ld be needed to meet the requirements would remain at 2.0 bill gal, the same volume that would have been

needed to meet the statutory level of 3.75 bill gal of advanced biofuel if 1.75 bill gal of cellulosic

biofuel were available. 96

- b a sed diesel requirement of 1.28 bill gal, as well as any other forms of advanced biofuel with a D code of 5 such as renewable diesel, heating oil, biogas, and imported sugarcane ethanol.

This approach to setting the advanced biofuel volume requirement wo uld minimize the impact of the advanced biofuel category on the supply problems associated with constraints on ethanol consumption. However this approach would ignore the availability of non

- cellulosic

advanced biofuel to fill the shortfall in cellulosic biofuel. It would reduce the market opportunities for other advanced biofuels (as compared to the other options), and thereby hinder the development of advanced biofuels that might otherwise help to meet the broader energy security and GHG reduction goals of Congress for the RFS program. Finally, as discussed below, this approach would result in greater reductions in advanced biofuel than are needed to account for the contribution of ethanol advanced biofuels to the blendwall. For these reasons, we

invit e comment on this approach but are not proposing it.

c. Option 3: Availability, Growth, and Limits on Ethanol Consumption

Neither Option 1 nor Option 2 address all the factors we believe are important in the determination of the applicable advanced b iofuel volume requirement. For instance, under Option 1 (using just availability to determine the appropriate volume of advanced biofuel), the

96 The 2.0 bill gal is composed of the proposed volume of biomass

- based diesel, 1.92 bill gallons ethanol equivalent,

an d the remaining volume of non

- cellulosic advanced biofuel, 0.08 bill gallons.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 90 of 111 significant impacts of constraints on ethanol consumption and the factors leading to a reduction

in the total vo lume of renewable fuel would not be reflected at all in our determination of the advanced biofuel requirement. On the other hand, under Option 2 (reducing the advanced biofuel requirement by the same amount that we reduce cellulosic biofuel), would impose unnecessary constraints on non

- ethanol advanced biofuels even though they do not contribute to the constraints on the volume of ethanol that can reasonably be consumed.

For these reasons we are proposing a third option that would address these issues by first summing the applicable volume requirements for cellulosic biofuel and biomass

- based diesel, and then adding available volumes of non

- ethanol advanced biofuel, including any biodiesel in excess of the 1.28 bill gal requirement as well as other avai lable non

- ethanol advanced biofuels such as renewable diesel, heating oil, and biogas. Under this approach, we consider o nly non

ethanol sources of advanced biofuel as these fuels are not limited by their ability to be consumed

as are ethanol blends. Thi s approach would help to ensure that the advanced biofuel requirement would include all available volumes of advanced biofuel which do not contribute to the supply concerns related to constraints on ethanol consumption. It would also provide for additiona l growth in volumes of advanced biofuel that would otherwise be lost due to the shortfall in cellulosic biofuel. Once the advanced biofuel volume requirement was set, the market would determine which advanced biofuels would be produced and sold to meet th e advanced biofuel requirement, including whether they would be ethanol or non

- ethanol. Thus under this approach we would not be mandating or determining what renewable fuels would in fact be produced and

sold.

We once again used a Monte Carlo approa ch to aggregate the ranges for cellulosic biofuel, biomass

- based diesel, and non

- ethanol advanced biofuel. The ranges and standardized distributions we used in this process are shown in Table IV.C.2.c

- 1, and the resulting distribution

for advanced biofuel is shown in Figure IV.C.2.c

Page 92 of 111 For the reasons discussed above, we propose that the advanced biofuel volume requirement would be set based on the Option 3 approach, within the range of 2.00

- 2.51 bill gal. Given that the volume requireme nt in the statute is 3.75 bill gal, this proposed range of advanced biofuel would represent a reduction of 1.24

- 1.75 bill gal. In comparison, the reduction in cellulosic biofuel that we are proposing in today's NPRM is 1.72

- 1.74 bill gal, and

the redu ction in total renewable fuel that we are proposing is 2.63

- 3.15 bill gal. The Option 3 approach to setting the advanced biofuel volume requirement would generate a volume that falls approximately midway between Options 1 and 2 for 2014.

The approach we are proposing in today's NPRM is based upon and fully consistent with the authorities provided in the statute for waiving volumes. The proposed reductions in the

volumes of advanced biofuel and total renewable fuel derive from our determination that th e industry and market will be unable to supply sufficient volumes in 2014 to meet the statutory mandates, either because of projected limitations in production and importation of qualifying renewable fuels, or projected limitations in the available infrast ructure to ensure that those fuels

are supplied to and consumed in the transportation sector . All of these limitations represent forms of inadequate supply and are permissible bases for exercising both the general waiver authority and the cellulosic waive r authority

.

As for the required volume of total renewable fuel, there are a variety of ways in which a specific value within the proposed range can be chosen for the volume of advanced biofuel that we require in the final rule. The table below shows th e values that correspond to the distribution in Figure IV.C.2.c

- 1 using several possible approaches.

Mean 2,202

Mode 2,099 25th percentile 2,086 50th percentile 2,178 75th percentile 2,289

In today's NPRM we are proposing to use the mean value of 2,202 mill gal for the volume requirement for advanced biofuel because we believe it best represents a neutral aim at adv anced biofuel volumes that could reasonably be supplied. However, we request comment on whether

one of the alternative values shown in Table IV.C.2.c

- 2, or some other approach, would be more appropriate as the basis for the required volume of advanced bio fuel in the final rule.

D. Summary of Proposed Volume Requirements for 201 4

For the reasons discussed above, we are proposing the volumes of total renewable fuel

and advanced biofuel as shown below.*** EO12866 Review

Advanced biofuel 3.75 2.00

- 2.51 2.20

Total renewable fuel 18.15 15.00

- 15.52 15.21

For the final rule, we may revise the ranges based on additional information that becomes available after publication of this NPRM. This information could include more recent Production Outlook Report required under §80.1449, production and consumption da ta for 2013,

and information from stakeholders.

With regard to the mean, we request comment on whether it is the most appropriate way to determine the volume within each of the ranges that we would require in the final rule, or

whether instead one of the alternatives shown in Tables IV.B.4

- 3 or IV.C.2.c

- 2, or some other approach, would be more appropriate. Nevertheless, as described above, w e do not believe that using either the low end or high end of the proposed ranges would be appropriate as the b asis for the applicable standards. A value between the low and high ends would better account for cases in which the actual values for some of the input volumes fall at the high end of their respective ranges while the actual value of other input volumes fall at the low end of their ranges.

We note that the two ranges shown in Table IV.D

- 1 were not independently derived and thus cannot be treated independently from one another in the determination of the appropriate volumes to finalize. Many of the sa me ranges of biofuel availability that were used in estimating the range of total renewable fuel were also used in estimating the range of advanced biofuel. This fact can be seen in the distribution of results from the Monte Carlo process, which shows a

d istinct correlation between total renewable fuel and advanced biofuel.

Figure IV.D

Results of Monte Carlo Process for Both Total Renewable Fuel and Advanced Biofuel*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 94 of 111 Because of this correlation, decisions for both total renewable fuel and advanced biofuel need to take this relationship into account. For example, it would not be appropriate to finalize a volume for total renewable fuel that is at the high end of its proposed range, while also finalizing a

volume for advanced biofuel that is at the l ow end of its proposed range. Doing so would result

in a demand for renewable fuels that either could not be filled with available volumes or could not reasonably be consumed.

The ranges that we are proposing for advanced biofuel and total renewable fue l determine the range of non

- advanced renewable fuel that would be needed. The majority of non

- advanced renewable fuel is ethanol made from corn starch, though as discussed in Section IV.B.2.d we would also expect some non

- ethanol renewable fuel as well, in the range of 1

- 25 mill gal. Taking this non

- ethanol renewable fuel into account, we used the results of the Monte Carlo process that generated the ranges shown in Table IV.D

- 1 to determine that the volume of corn

ethanol that would be needed would be 12.94

- 13.07 bill gal. This range represents an increase in comparison to 2012 corn

- ethanol consumption

, which was about 12.5 bill gal

. 97 While this

range represe nts a reduction in comparison to the statutory volumes for 2014, it nonetheless represents an increase relative to projected 2013 corn

- ethanol consumption of about 12.3 bill gal. 98 For comparison, this reduction in corn

- ethanol volume for 2014 is about 90% of the size of the proposed reduction in advanced biofuel. Thus under our proposed approach, both non

advanced renewable fuels and advanced biofuels are contributing to the necessary reductions needed to attain renewable fuel volumes that can reasonably be supplied and consumed. We request comment on our proposed approach and on alternative approaches that may be applied to

E. Volume Requirements for 2015 and Beyond

In enacting the RFS program, Congress anticipated and intended to promote substantial, sustained growth in biofuel production and consumption

– beyond the levels that have been

achieved to date

– though it did so in the context of forecasts of continually growing transportation fuel consumption. As explained in Section IV.B, gasoline demand has declined in the years since EISA was enacted in 2007 and i s projected to continue to do so. A s a result, the gasoline pool will be able to absorb about 2.3 bill gal less ethanol as E10 in 2014 than it would have been possible to absorb if the gasoline use projection in AEO2007 had been realized. While we recogn ize this change in circumstances, we continue to support the objective of continued growth in renewable fuel production and consumption, as well as the central policy goals underlying the RFS program: reductions in greenhouse gas emissions, enhanced energy security, economic development, and technological innovation. We recognize that the issues concerning availability of qualifying renewable fuels and the consumption of ethanol that are discussed above with respect to the 2014 RFS standards will continue to be relevant in 2015 and beyond. Our objective in this rulemaking is to develop a general approach for determining appropriate volume requirements that can be applied not only to 2014, but also for 2015 and beyond . Any such approach would, of course, fully consider comments received in response to

this NPRM and would account for new and improved data and changes in rel evant circumstances over time. As we have underscored throughout this proposal, we look forward to engagement with stakeholders on all relevant aspects of the proposed approach.

We believe that the general approach reflected in today’s proposa l is consistent with the goals of the underlying statute and will put the RFS program on a manageable trajectory while supporting continued growth in renewable fuels over time. In future years, we would expect to use the most recently available informatio n to update the analyses used to project volumes in

each of these areas:

• Volume of ethanol that could be consumed , including reasonably achievable growth in capacity to consume higher ethanol blends such as E15 and E85

• Available volumes of cellulosic biofuel

• Available volumes of biomass

- based diesel

• Available volumes of advanced biofuel

• Available volumes of non

- advanced renewable fuel

• Amount of carryover RINs

In addition to these factors, the appro ach we are proposing today would also account for changes in circumstances over time, including the substantial efforts underway to increase the volume of biofuel produced and consumed in the United States. Many companies are continuing to invest

in effor ts ranging from research and development to the construction of commercial scale facilities to increase the production potential of next generation biofuels. Many of these projects have received financial support from government agencies. Two examples ar e the DOE’s*** EO12866 Review

- E program, which aims to advance high

- potential, high

- impact energy technologies that are too early for private sector investment, and DOE’s Integrated Biorefinery Program, which provides grants and works in partnership with industry to de velop, build, operate, and validate integrated biorefineries at various scales at locations across the country. 99 USDA’s Biorefinery Assistance Program, which provides loan guarantees for the development and construction of

commercial scale biorefineries i s another example. 100 Many of these new projects are focused on producing non

- ethanol fuels, including bio

- based hydrocarbons (gasoline, diesel, and jet fuel), gaseous fuels (CNG and LNG), or more energy

- dense alcohols such as butanol. EPA is currently eva luating a number of new pathways to allow these fuels to generate RINs under the RFS program if the applicable feedstock, fuel type, and greenhouse gas reduction requirements are met. As these new fuels and fuel volumes come online, the proposed methodolo gy will automatically incorporate them into the development of the standards for the following year.

Simultaneously, efforts are underway to increase the availability, awareness, and acceptance of gasoline fuel blends containing greater than 10 percent et hanol as expanded consumption of this fuel could play a role in the future. For instance, EPA has taken a series of regulatory steps to enable E15 to be sold in the U.S. In 2010 and 2011, EPA issued partial waivers to enable use of E15 in model year 2001 and newer vehicles, and in June of 2011, EPA finalized regulations to preven t misfueling of vehicles, engines, and equipment not covered by the partial waiver decisions. Other federal and state agencies have also taken steps to help foster the inclusion of E15 in the marketplace. We recognize that there remain a number of obstac les to increased E15 consumption . We request comment on what actions, on the part of government
as well as industry and other stakeholders , could be taken to overcome these obstacles and to enable E15 consumption to increase.

With regard to E85, the po rtion of th e estimated 11.5 million FFV fleet (in 2013) 101
having reasonable access to the existing E85 retail infrastructure (approximately 3,000 stations nationwide) represents a potential market of over 1 billion gallons of E85 consumption. 102 While there are many factors that may contribute to a customer’s choice of which fuel to purchase, a recent study by the National Association of Convenience Stores found that for 71% of customers, price was the most important factor in their decision on where to purchase their

fuel. 103 Historically, E85 has been more expensive than E10 on an energy

- content adjusted basis which has likely been a key factor in the low sales volumes. Recent data collected by EIA

su ggests that at least in some parts of the country the price relationship between E10 and E85 may be changing. In a Today in Energy article published on September 19, 2013, EIA presented data showing that in a collection of Midwestern states E85 retail pri ces were less than E10 retail prices on an energy

- content adjusted basis in July 2013, the most recent month for which

Page 97 of 111 information was available. 104 This change in price relationship between E10 and E85 coincides with reported increases in sales volumes of E85 in Iowa and Minnesota, two states in which E85 sales volumes are publically available. 105 If the conditions that have led to this price relationship continue in the future, E85 sales volumes are likely to continue to increase.

In addition to the potential for increased consumption of E85 when considering the existing infrastructure and vehicle fleet, there is also substantial opportunity to increase ethanol consumption in higher level ethanol blends through growth in the FFV fleet and E85

infrastr ucture. The number of stations offering E85 is currently increasing at a rate of approximately 300 new stations per year. 106 In 2012 USDA announced a goal to help retail station owners install as many as 10,000 ethanol blender pumps by 2017. 107 Growth Energ y has a “Blend Your Own Ethanol” program to encourage the installation of ethanol blender

pumps. These efforts, combined with the potential for these higher level ethanol blends to decrease consumer fuel costs in the future under appropriate market circum stances, could lead to a significant increase in the amount of ethanol than can be consumed as a transportation fuel in the United States in future years. As a benchmark, if every FFV currently in the fleet had access

to E85 and chose to use it ex clusively , the total consumption of these vehicles would be approximately 8 billion gallons per year. The size of the FFV vehicle fleet also continues to increase, and is expected to grow by approximately 1 million vehicles from 2013 to 2014, with

sales r ecently in excess of 2 million vehicles per year. 108 109 EPA’s recently proposed credit for vehicle manufacturers under the light

- duty greenhouse gas standards could help encourage the

continuation such sales into the future. 110 Ongoing growth in the size of the FFV fleet and the number of E85 pumps could be accelerated by increases in demand from customers for E85 fuel, which has the potential to support a rapid growth in E85 infrastructure. Under the proposed framework for the 2014 standards, any such g rowth in capacity for ethanol consumption would continuously be reflected in the standards set for the following year.

At the same time, w e recognize that a number of challenges must be overcome in order to fully realize the potential for higher levels of production and consumption of higher

- level ethanol

blends and of renewable fuels generally in the United States . We also recognize that, while the RFS program is a central element of our domestic biofuels policy, a rang e of other tools, programs, and actions have the potential to play an important complementary role. We request comment on what actions could be taken by various industry and other private stakeholders, as well by the government, to help overcome the se cha llenges and to minimize the need for adjustments in the statutory renewable fuel volume requirements in the future.

Page 98 of 111 V. Proposed Percentage Standards for 201 4

A. Background

The renewable fuel standards are expressed as volume percentages and are used by each refiner or importer to determine their RVO. Since there are four separate standards under the RFS2 program, there are likewise four separate RVOs applicable to each obligated party. Each standard applies to the sum of all gasoline and diesel produced or imported. The applicable percentage

standards are set so th at if every obligated party meets the percentages, then the amount of renewable fuel, cellulosic biofuel, biomass

- based diesel, and advanced biofuel used will meet the volumes required on a nationwide basis.

As discussed in Section II. C , we are proposing a required volume of cellulosic biofuel for

2014 of 17 million ethanol

- equivalent gallons. The volume we select for the final rule will be used as the basis for setting the percentage standard for cellulosic biofuel for 201 4

. We are also

propos ing to reduce the advanced biofuel and total renewable fuel volumes. The biomass

- based

diesel volume for 2014 has been proposed to be maintained at 1.28 billion gallons. The volumes

to be used to determine the four proposed percentage standards are shown in Table V.A

- 1.

Table V.A

Cellulosic biofuel 17 mill gal

- based diesel 1.28 bill gal

Advanced biofuel 2.20 bill gal

a Due to the manner in which the percentage standards are calculated, all volumes are given in terms of ethanol

equivalent except for biomass

- based diesel which is given in terms of physical volume

As with previous years’ renewable fuels standards determination, the formulas used in deriving the annual standards are based in part on estimates of the volumes of gasoline and diesel fuel, for both highway and nonroad uses, that are projected to be used in the year in which the standards will apply. Producers of othe r transportation fuels, such as natural gas, propane, and electricity from fossil fuels, are not subject to the standards, and volumes of such fuels are not used in calculating the annual standards. Since the standards apply to producers and importers of gasoline and diesel, these are the transportation fuels used to set the standards, and then again to determine the annual volume obligations of an individual gasoline or diesel producer or importer.

Page 99 of 111 The following formulas are used to calculate the four percentage standards applicable to producers and importers of gasoline and diesel (see §80.1405):

Where

Std CB,i = The cellulosic biofuel standard for year i, in percent.

Std BBD,i = The biomass

- based diesel standard (ethanol

- equivalent basis) for year i, in percent.

Std AB,i = The advanced biofuel standard for year i, in percent.

Std RF,i = The renewable fuel standard for year i, in percent.

RFV CB,i = Annual volume of cellulosic biofuel required by section 211(o) of the Clean Air

Act for year i, in gallons.

RFV BBD,i = Annual volume of biomass

- based diesel required by section 211(o) of the Clean

Air Act for year i, in gallons.

RFV AB,i = Annual volume of advanced biofuel required by section 211(o) of the Clean Air

Act for year i, in gallons.

RFV RF,i = Annual volume of renewable fuel required by section 211(o) of the Clean Air Act

for year i, in gallons.

G i = Amount of gasoline projected to be used in the 48 contiguous states and Hawaii, in

year i, in gallons.

D i = Amount of diesel projected to be used in the 48 contiguous states and Hawaii, in

year i, in gallons. This value exclud es diesel used in ocean

refiners in year i, in gallons, in any year they are exempt per §§80.1441 and 80.1442, respectively. For 2014 , this value is zero. See further discussion in

Section V.B.2 below.

The four separate renewable fuel stand ards for 201 4 are based on the gasoline and diesel consumption volumes projected by EIA. The Act requires EPA to base the standards on an EIA estimate of the amount of gasoline and diesel that will be sold or introduced into commerce for that year. The p rojected volumes of gasoline and diesel that will be used to calculate the final

201 4 percentage standards will be provided to EPA by EIA

. To estimate the gasoline and diesel projected volumes f

or the purposes of this proposal, we hav e used EIA's Short

- Term Energy Outlook (STEO) 111 for the gasoline projection and EIA's Annual Energy Outlook 201 3 Early

Release 112 for the diesel projection. Gasoline and diesel volumes are adjusted to account for renewable fuel contained in the EIA projectio ns. The projected volumes of ethanol and biodiesel used to calculate the final percentage standards will be provided to EPA by EIA

2. S mall Refineries and Small Refiners

In CAA section 211(o)(9), enacted as part of the Energy Policy Act of 2005, Congress provided a temporary exemption to small refineries (those refineries with a crude throughput of no more than 75,000 barrels of crude p er day) through December 31, 2010. In our initial rulemaking to implement the new RFS program

, 114 we exercised our discretion under section 211(o)(3)(B) and extended this temporary exemption to the few remaining small refiners that

met the Small Business Ad ministration’s (SBA) definition of a small business (1,500 employees or less company

- wide) but did not meet the statutory small refinery definition as noted above. 115
Because EISA did not alter the small refinery exemption in any way, the RFS2 program

reg ulations maintained the exemptions for gasoline and diesel produced by small refineries and small refiners through 2010 (unless the exemption was waived). 116

Congress provided two ways that small refineries could receive a temporary extension of the exempt ion beyond 2010. One was based on the results of a study conducted by the Department of Energy (DOE) to determine whether small refineries would face a disproportionate economic hardship under the RFS program. In March of 2011

, DOE evaluated the impacts of the RFS program on small entities and concluded that some small refineries would suffer a disproportionate hardship. 117 The other way that small refineries could receive a temporary extension is based on EPA determination of disproportionate economic har dship on a

case

- by

- case basis in response to refiner petitions

. 118 EPA has granted some exemptions pursuant to this process , as recently as 2013. However, at this time, no exemptions have been approved for 2014 . Therefore, for this proposal we have calc ulated the 2014 standards without a small refinery/small refiner adjustment.

However, if an individual small refinery or small refiner requests an exemption and is approved prior to issuance of the final rule , the final standards will be adjusted to account for the exempted volumes of gasoline and diesel. A ny requests for exemptions that are approved after

the release of the final 201 4 RFS standards will not affect the 201 4 standards. As stated in the

final rule establishing the 2011 standards, “EPA believes the Act is best interpreted to require issuance of a single annual standard in November that is applicable in the following calendar year, thereby providing advance notice and certainty to obligated parti es regarding their regulatory requirements. Periodic revisions to the standards to reflect waivers issued to small refineries or refiners would be inconsistent with the statutory text, and would introduce an undesirable level of uncertainty for obligated parties.” Thus, after the 201 4 standards are

Page 102 of 111 finalized, any additional exemptions for small refineries or small refiners that are issued will not

affect those 2014 standards.

3. Proposed Standards

As specified in the March 26, 2010 RFS2 final rule

, 119 the percentage standards are based

on energy

- equivalent gallons of renewable fuel, with the cellulosic biofuel, advanced biofuel, and total renewable fuel standards based on ethanol equivalence and the biomass

- based diesel standard based on biodiesel equi valence. However, all RIN generation is based on ethanol

equivalence. For example, the RFS2 regulations provide that production or import of a gallon of qualifying biodiesel will lead to the generation of 1.5 RINs. In order to ensure that demand for

1.2 8 billion physical gallons of biomass

- based diesel will be created in 2014 , the calculation of

the biomass

- based diesel standard provides that the required volume be multiplied by 1.5. The

net result is a biomass

- based diesel gallon being worth 1.0 gallon toward the biomass

- based diesel standard, but worth 1.5 gallons toward the other standards.

The levels of the percentage standards would be reduced if Alaska or a U.S. territory chooses to participate in the RFS2 program, as gasoline and diesel produced in or imported into that state or territory would then be subject to the standard. Neither Alaska nor any U.S. territory has chosen to participate in the RFS2 program at this time, and thus the value of the related terms

in the calculation of the standar ds is zero.

Note that because the gasoline and diesel volumes estimated by EIA include renewable fuel use, we must subtract the total renewable fuel volumes from the total gasoline and diesel volumes to get total non

- renewable gasoline and diesel volumes . The values of the variables

described above are shown in Table V.B.3

- 1. 120 Terms not included in this table have a value of

zero.

Page 106 of 111 V I I. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improvi ng Regulation and Regulatory Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is a "significant regulatory action” because it raises novel legal or policy issues arising out of legal mandates, the President’s priorities, or the principles set forth in the Executive Order. Accordingly, EPA submitted this action to the Office of Management and Budget (OMB) for review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011) and any changes made in response to OMB recommendations have been documented in the docket for

this action.

The economic impacts of the RFS2 program on regulated parties, including the impacts

of the volumes of renewable fuel specified in the statute , were already addressed in the RFS2 final rule promulgated on March 26, 2010 (75 FR 14670). With the exception of biomass

- based diesel, this action proposes standards applicable in 2013 that would be reduced from those analyzed in the RFS2 final rule. T he impacts of the proposed 2014 and 2015 volumes of

biomass

- based diesel were addressed in the final rule establishing the 2013 volume requirement of 1.28 bill gal (77 FR 59458).

B. Paperwork Reduction Act

There are no new information collection requirements associated with the standards in this notice of proposed r

ulemaking

. The standards being proposed today would not impose new or different reporting requirements on regulated parties. The existing information collection requests (ICR) that apply to the RFS program are sufficient to address the reporting requirements in the regulations.

An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a curr ently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

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 s 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 e ntities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of today's proposed rule on small entities, small entity is defined as: (1) a small business as defined by the Small Business Administration’s*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 107 of 111 (SBA) regulations at 13 CFR 121.201; (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 organiz ation that is any not

- for

- profit enterprise which is independently owned and operated and is not dominant in its field.

After considering the economic impacts of today’s proposed rule on small entities, we certify that this proposed action will not have a significant economic impact on a substantial number of small entities. This rule proposes that the annual volume requirement for cellulosic

biofuel for 201 4 would be reduced from the statutory volume of 1.75 bill gal

. We are also proposing to reduce th e annual volume requirements for advanced biofuel and total renewable

fuel. The impacts of the RFS2 program on small entities were already addressed in the RFS2 final rule promulgated on March 26, 2010 (75 FR 14670), and this proposed rule will not impose any additional requirements on small entities beyond those already analyzed . However, w e continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts.

D. Unfunded Mandates Reform Act

This proposed action contains no Federal mandates under the provisions of Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531

- 1538 for State, local, or tribal governments or the private sector. This action impl ements mandate(s) specifically and explicitly set forth by the Congress in Clean Air Act section 211(o) without the exercise of any policy discretion by EPA. Therefore, this action is not subject to the requirements of sections 202 or

205 of the UMRA.

This action is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. This proposed rule only applies to gasoline, diesel, and renewable fue l producers, importers, distributors and marketers and merely proposes the 201 4 annual standards for the RFS

program.

E. Executive Order 13132: Federalism

This action 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. This action proposes the 201 4 annual st andards for the RFS program and only applies to gasoline, diesel, and renewable fuel producers, importers,

distributors and marketers. 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.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 108 of 111 F. Executive Order 13175: Consultation and Coordination with Indian Tribal

Governme nts

This proposed action does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). This proposed rule will be implemented at the Federal level and affects transportation fuel refiners, blenders, marketers, distributors, importers, exporters, and renewable fuel producers and importers. Tribal governments would be affected only to the extent they purchase and use regulated fuels. Thus, Executive Order 13175 does not apply to this action.

EPA specifically solicits additional comment on this proposed action from tribal officials.

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

EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required under

section 5

- 501 of the EO has the potential to influence the regulation. This propo sed action is not subject to EO 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 (section 211(o) of the Clean Air Act)

.

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

This action is not a “significant energy action” as defined in Executive Order 13211, “Actions Concerning Regulations That Signifi cantly 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. This action simply proposes the annual standards for

renewable fue l under the RFS program for 201 4

.

I. National Technology Transfer and 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 pr ocedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus stand ards.*** EO12866 Review

- Revised version

- Do Not Cite, Quote, or Release During Review ***

Page 109 of 111 This proposed rulemaking does not involve technical standards. Therefore, EPA is not considering the use of any voluntary consensus standards.

J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations an d Low

- Income Populations

Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low

income populat ions in the United States.

EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low

- income populations because it does not affect the level of protection provided to human health or the environment. This action does not relax the control measures on sources regulated by the RFS regulations and therefore

will not cause emissions increases from t hese sources.*** EO12866 Review
