Renewable Fuel Standard Program: 
Standards for 2020 and Biomass- Based Diesel Volume for 2021 and Other Changes 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Final rule. 
SUMMARY : Under section 211 of the 
Clean Air Act, the Environmental Protection Agency (EPA) is required to set renewable fuel percentage standards every year. This action establishes the annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel that apply to gasoline and diesel transportation fuel produced or imported in the year 2020. Relying on statutory waiver authority that is available when the projected cellulosic biofuel production volume is less than the applicable volume specified in the statute, EPA is establishing volume requirements for cellulosic biofuel, advanced biofuel, and total renewable fuel that are below the statutory volume targets. We are also establishing the applicable volume of biomass-based diesel for 2021. In addition, we are finalizing changes to the percentage standard calculations to account for volumes of gasoline and diesel we project will be exempted from the renewable volume obligations. Finally, this action finalizes several regulatory changes to the Renewable Fuel Standard (RFS) program including new pathways, flexibilities for regulated parties, and clarifications of existing regulations. 
DATES : This final rule is effective on 
April 6, 2020.

I. Executive Summary 
The Renewable Fuel Standard (RFS) 
program began in 2006 pursuant to the requirements in Clean Air Act (CAA) section 211(o) that were added through the Energy Policy Act of 2005 (EPAct). The statutory requirements for the RFS program were subsequently modified through the Energy Independence and Security Act of 2007 (EISA), leading to the publication of major revisions to the regulatory requirements on March 26, 2010.
1EISA’s stated goals include 
moving the United States (U.S.) toward ‘‘greater energy independence and security [and] increas[ing] the production of clean renewable fuels.’’
2 
The statute includes annual volume 
targets and requires EPA to translate those volume targets (or alternative volume requirements established by EPA in accordance with statutory waiver authorities) into compliance obligations that obligated parties must meet every year. In this action we are establishing the applicable volumes for cellulosic biofuel, advanced biofuel, and total renewable fuel for 2020, and biomass-based diesel (BBD) for 2021.
3 
We are also finalizing changes to the 
percentage standard calculations to account for volumes of gasoline and diesel we project will be exempted from the renewable volume obligations, and establishing the annual percentage standards (also known as ‘‘percent standards’’) for cellulosic biofuel, BBD, advanced biofuel, and total renewable fuel that would apply to gasoline and 
diesel produced or imported in 2020.
4 Finally, we are finalizing several 
regulatory changes to the RFS program 
to facilitate the implementation of this program going forward including new pathways, flexibilities for regulated parties, and clarifications of existing regulations. 
Today, nearly all gasoline used for 
transportation purposes contains 10 percent ethanol (E10), and on average diesel fuel contains nearly 5 percent of biodiesel and renewable diesel.
5 
However, the market has fallen well short of the statutory volumes for cellulosic biofuel, resulting in shortfalls in the advanced biofuel and total renewable fuel volumes. In this action, we are establishing a volume requirement for cellulosic biofuel at the level we project to be available for 2020, along with an associated applicable percentage standard. For advanced biofuel and total renewable fuel, we are finalizing volume requirements using the ‘‘cellulosic waiver authority’’ that result in advanced biofuel and total renewable fuel volume requirements that are lower than the statutory targets by the same magnitude as the reduction in the cellulosic biofuel reduction. This would effectively maintain the implied statutory volumes for non-cellulosic biofuel and conventional biofuel.
6 
The resulting volume requirements 
for 2020 are shown in Table I–1. Relative to the levels finalized for 2019, the 2020 volume requirements for cellulosic biofuel, advanced biofuel and total renewable fuel would be higher by approximately 170 million gallons. This entire increase for each category is attributable to the increased projection of cellulosic biofuel production in 2020 (see Section III for a further discussion of our cellulosic biofuel projection). We are also establishing the volume 
requirement for BBD for 2021 at 2.43 billion gallons. This volume is equal to the BBD volume finalized for 2020.

cThe 2020 BBD volume requirement of 2.43 billion gallons was established in the 2019 final rule (83 FR 63704, December 11, 2018) . 
A. Approach To Setting Volume 
Requirements 
For advanced biofuel and total 
renewable fuel, we are reducing the statutory volumes based on the ‘‘cellulosic waiver authority’’ that result in advanced biofuel and total renewable fuel volume requirements that are lower than the statutory targets by the same magnitude as the reduction in the cellulosic biofuel applicable volume. Further discussion of our cellulosic waiver authority is found in Section II. This follows the same general approach as in the 2018 and 2019 final rules, as well as the 2020 proposed rule. The volumes for cellulosic biofuel, advanced biofuel, and total renewable fuel exceed the required volumes for these fuel types in 2019. 
B. Cellulosic Biofuel 
The CAA requires EPA to 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 volume used to set the annual cellulosic biofuel percentage standard to the projected volume available. In this rule we are establishing a cellulosic biofuel volume requirement of 0.59 billion ethanol- equivalent gallons for 2020 based on our projection. This volume is 0.17 billion ethanol-equivalent gallons higher than the cellulosic biofuel volume finalized for 2019. Our projection in Section III considers many factors, including the estimate of cellulosic biofuel production received from the Energy Information Administration (EIA);
7RIN generation 
data for past years and 2019 to date that is available to EPA through the EPA Moderated Transaction System (EMTS); the information we have received regarding individual facilities’ capacities, production start dates, and biofuel production plans; a review of cellulosic biofuel production relative to EPA’s projections in previous annual rules; and EPA’s own engineering judgment. To project cellulosic biofuel production for 2020 we used the same general methodology as in the 2018 and 2019 final rules, together with updated data. 
C. Advanced Biofuel 
If we reduce the applicable volume of 
cellulosic biofuel below the volume 
specified in CAA section 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 refer to this as the ‘‘cellulosic waiver authority.’’ The conditions that caused us to reduce the 2019 volume requirement for advanced biofuel below the statutory target remain relevant in 2020. 
As in the 2019 final rule, we 
investigated the projected availability of non-cellulosic advanced biofuels in 2020. In Section IV, we describe our consideration of many factors, including: 
•The ability of the market to make 
advanced biofuels available, 
•The ability of the standards we set 
to bring about market changes in the time available, 
•The potential impacts associated 
with diverting biofuels and/or biofuel feedstocks from current uses to the production of advanced biofuel used in the U.S., 
•The fact that the biodiesel tax credit 
is currently not available for 2020, 
•Current tariffs on imports of 
biodiesel from Argentina and Indonesia and the proposal to change those tariffs, and 
•The cost of advanced biofuels 
We also considered the size of the 
carryover RIN bank. Based on these considerations, we have determined that the statutory volume target for advanced biofuel should be reduced by the same amount as the reduction in the statutory volume target for cellulosic biofuel, consistent with our July 29, 2019, proposal (‘‘the July 29 proposal’’). Specifically, the statutory volume target for advanced biofuel should be reduced by 9.91 billion gallons. This maintains the implied statutory volume requirement for non-cellulosic advanced biofuel of 4.5 billion gallons, and results in a final advanced biofuel volume requirement for 2020 of 5.09 billion gallons, which is 0.17 billion gallons higher than the advanced biofuel volume requirement for 2019. 
D. Total Renewable Fuel 
As we have articulated in previous 
annual standard-setting rulemakings,
8 
we believe that the cellulosic waiver 
authority is best interpreted to require equal reductions in advanced biofuel and total renewable fuel. Consistent with previous years, we are reducing total renewable fuel by the same amount as the reduction in advanced biofuel, such that the resulting implied volume requirement for conventional renewable fuel would be 15 billion gallons, the same as the implied volume requirement in the statute. The result is that the final 2020 volume requirement is 20.09 billion gallons. 
E. 2021 Biomass-Based Diesel 
In EISA, Congress specified increasing 
applicable volumes of BBD through 
2012. Beyond 2012, Congress stipulated that EPA, in coordination with DOE and USDA, was to establish the BBD volume based on a review of the implementation of the program during calendar years specified in the tables in CAA 211(o)(B)(i) and other statutory factors, provided that the required volume for BBD could not be less than 1.0 billion gallons. Starting in 2013, EPA has set the BBD volume requirement above the statutory minimum, most recently resulting in 2.43 billion gallons for 2020. In this rule we are maintaining the BBD volume for 2021 at 2.43 billion gallons. 
VerDate Sep<11>2014 20:53 Feb 05, 2020 Jkt 250001 PO 00000 Frm 00004 Fmt 4701 Sfmt 4700 E:\FR\FM\06FER2.SGM 06FER2lotter on DSKBCFDHB2PROD with RULES27019 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations 
9See 81 FR 80828 (November 16, 2016). 
10See 84 FR 36765 (July 29, 2019). 11See 80 FR 77420 (December 14, 2015); CAA 
section 211(o)(7)(A)(ii). Given current and recent market 
conditions, the advanced biofuel 
requirement is driving the production and use of biodiesel and renewable diesel volumes over and above volumes required through the separate BBD standard, and we expect this to continue. While EPA continues to believe it is appropriate to maintain the opportunity for other advanced biofuels to compete for market share, the vast majority of the advanced biofuel obligations in recent years have been satisfied with BBD. Thus, after a review of implementation of the program to date and considering the statutory factors, we are establishing, in coordination with USDA and DOE, an applicable volume of BBD for 2020 of 2.43 billion gallons. 
F. Annual Percentage Standards 
The renewable fuel standards are 
expressed as a volume percentage and 
are used by each refiner and importer of fossil-based gasoline or diesel to determine their renewable fuel volume obligations. 
Four separate percentage standards 
are required under the RFS program, corresponding to the four separate renewable fuel categories 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. On October 28, 2019, we proposed changes to our percentage standard formulas in 40 CFR 80.1405. (‘‘October 28 Proposal’’). These changes were intended to project the exempted volume of gasoline and diesel due to small refinery exemptions, regardless of whether we grant those exemptions prior or after the annual rule. For 2020, we proposed to project exempt volumes are based on a three-year average of the relief recommended by the Department of Energy (DOE) for 2016–2018. In this action, we are finalizing these proposed changes. These changes result in increases to the percentage standards as compared to the percentage standards in the July 29 proposal. 
Consistent with these changes, we are 
also announcing our general policy approach to small refinery exemptions going forward, including for now- pending 2019 petitions as well as for future 2019 and 2020 petitions. Although final decisions on any exemption petition must await EPA’s receipt and adjudication of those petitions, EPA intends to grant relief consistent with DOE’s recommendations where appropriate. This policy extends to DOE’s recommendations of partial (50%) relief: Where appropriate, we intend to grant 50% relief where DOE recommends 50% relief. 
The volume of transportation gasoline 
and diesel used to calculate the proposed percentage standards was based on Energy Information Administration’s (EIA) October 2019 Short Term Energy Outlook (STEO), minus an estimate of fuel consumption in Alaska. The final applicable percentage standards for 2020 are shown in Table I.B.6–1. Details, including the projected gasoline and diesel volumes used, can be found in Section VII.

G. Amendments to the RFS and Fuels Programs Regulations 
In implementing the RFS program 
EPA has identified several areas where regulatory changes would assist EPA in implementing the RFS program in future years. EPA requested comment on several of these regulatory changes in the July 29 proposal: Clarification of diesel RVO calculations, pathway petition conditions, a biodiesel esterification pathway, distillers corn oil and distillers sorghum oil pathways, and renewable fuel exporter provisions. Each of these regulatory changes is discussed in greater detail in Section IX. 
Additionally, we proposed a number 
of changes to the RFS regulations as part of the proposed Renewables Enhancement and Growth Support (REGS) Rule.
9EPA noted that it was 
considering finalizing several of those proposed changes along with the 2020 RVO final rule,
10and are now finalizing 
the REGS Rule provisions listed below. 
•Flexibilities for Renewable Fuel 
Blending for Military Use (REGS 
Section VIII.E) 
•Heating Oil Used for Cooling (REGS 
Section VIII.F) 
•Separated Food Waste Plans (REGS 
Section VIII.G) 
•Additional Registration Deactivation 
Justifications (REGS Section VIII.J) 
•New RIN Retirement Section (REGS 
Section VIII.L) 
•New Pathway for Co-Processing 
Biomass With Petroleum To Produce Cellulosic Diesel, Jet Fuel, and 
Heating Oil (REGS Section VIII.M) 
•Other Revisions to the Fuels Program 
(REGS Section IX) 
The other provisions proposed in the 
REGS Rule remain under consideration 
but are not being finalized at this time. 
H. Response to Remand of 2016 
Standards Rulemaking 
In 2015, EPA established the total 
renewable fuel standard for 2016, relying in part on the general waiver authority under a finding of inadequate domestic supply.
11Several parties 
challenged that action, and the U.S. Court of Appeals for the D.C. Circuit, in 
Americans for Clean Energy v. EPA, 864 
F.3d 691 (2017) (hereafter ‘‘ACE’’), 
vacated EPA’s use of the general waiver authority under a finding of inadequate domestic supply, finding that such use exceeded EPA’s authority under the Clean Air Act. Specifically, EPA had impermissibly considered demand-side factors in its assessment of inadequate domestic supply, rather than limiting that assessment to supply-side factors. The court remanded the rule back to EPA for further consideration in light of the court’s ruling. 
In the July 29 proposal, we proposed 
that the applicable 2016 volume requirement for total renewable fuel and the associated percentage standard should not be changed. In light of the many comments received, we are still actively considering this issue. We are therefore not taking final agency action on this issue in today’s final rule. We are instead deferring action on this issue to a separate action, which we anticipate in early 2020. 
II. Authority and Need for Waiver of 
Statutory Applicable Volumes 
The CAA provides EPA with the 
authority to promulgate volume requirements below the applicable volume targets specified in the statute under specific circumstances. This section discusses those authorities. As described in the executive summary, we are setting the volume requirement for cellulosic biofuel at the level we project to be available for 2020, and an associated applicable percentage standard. For advanced biofuel and total renewable fuel, we are setting volume requirements and associated applicable percentage standards, based on use of the ‘‘cellulosic waiver authority’’ that would result in advanced biofuel and total renewable fuel volume requirements that are equivalent to the reduction in the cellulosic biofuel

Advanced biofuels are required to have lifecycle GHG emissions that are at least 50% less than the baseline defined in EISA. Non-advanced biofuels are required to have lifecycle GHG emissions that are at least 20% less than the baseline defined in EISA unless the fuel producer meets the grandfathering provisions in 40 CFR 80.1403. Beginning in 2015, all growth in the volumes established by Congress come from advanced biofuels.

Finding for the 2020 Final Rule.’’ reduction. This would effectively 
maintain the implied statutory volumes for non-cellulosic advanced and conventional renewable fuel. 
A. Statutory Authorities for Reducing 
Volume Targets 
In CAA section 211(o)(2), Congress 
specified increasing annual volume targets for total renewable fuel, advanced biofuel, and cellulosic biofuel for each year through 2022. However, Congress also recognized that under certain circumstances it would be appropriate for EPA to set volume requirements at a lower level than reflected in the statutory volume targets, and thus provided waiver provisions in CAA section 211(o)(7). Congress also specified increasing annual volume targets for BBD through 2012 and authorized EPA to set volume requirements for subsequent years (i.e., after 2012) in coordination with USDA and DOE, and based upon consideration of specified factors. 
1. Cellulosic Waiver Authority 
Section 211(o)(7)(D)(i) of the CAA 
provides that if EPA determines that the 
projected volume of cellulosic biofuel production for a given year is less than the applicable volume specified in the statute, then EPA must reduce the applicable volume of cellulosic biofuel required to the projected volume available for that calendar year. In making this projection, EPA may not ‘‘adopt a methodology in which the risk of overestimation is set deliberately to outweigh the risk of underestimation’’ but must make a projection that ‘‘takes neutral aim at accuracy.’’ API v. EPA, 
706 F.3d 474, 479, 476 (D.C. Cir. 2013). Pursuant to this provision, EPA has set the cellulosic biofuel requirement lower than the statutory volume for each year since 2010. As described in Section III.D, the projected volume of cellulosic biofuel production for 2020 is less than the 10.5 billion gallon volume target in the statute. Therefore, for 2020, we are finalizing a cellulosic biofuel volume lower than the statutory applicable volume, in accordance with this provision. 
CAA section 211(o)(7)(D)(i) also 
provides EPA with the authority to reduce the applicable volume of total renewable fuel and advanced biofuel in years when it reduces the applicable volume of cellulosic biofuel under that provision. The reduction must be less than or equal to the reduction in cellulosic biofuel. For 2020, we are reducing the applicable volumes of advanced biofuel and total renewable fuel under this authority. EPA has used the cellulosic waiver 
authority to lower the advanced biofuel 
and total renewable fuel volumes every year since 2014 as a result of waiving the cellulosic volumes. Further discussion of the cellulosic waiver authority, and EPA’s interpretation of it, can be found in the preamble to the 2017 final rule.
12 
In this action we are using the 
cellulosic waiver authority to reduce the statutory volume targets for advanced biofuel and total renewable fuel by equal amounts, consistent with our long-held interpretation of this provision and our approach in setting the 2014–2019 standards. This approach considers the Congressional objectives reflected in the volume tables in the statute, and the environmental objectives that generally favor the use of advanced biofuels over non-advanced biofuels.
13As described in Section IV, 
we are reducing the advanced biofuel volume under the cellulosic waiver authority by the amount of the reduction in cellulosic biofuel and providing an equal reduction under the cellulosic waiver authority in the applicable volume of total renewable fuel. We are taking this action both because we do not believe that the statutory volumes can be achieved, and because we believe that backfilling of the shortfall in cellulosic with advanced biofuel would not be appropriate in light of concerns about high costs of the advanced biofuels and the potential for feedstock switching. The volumes of advanced biofuel and total renewable fuel resulting from this exercise of the cellulosic waiver authority provide for an implied volume allowance for conventional renewable fuel of 15 billion gallons, and an implied volume allowance for non-cellulosic advanced biofuel of 4.5 billion gallons, equal to the implied statutory volumes for 2020. 
As discussed in Section IV, we also believe that the resulting volume of advanced biofuel is attainable, and that the resulting volume of total renewable fuel can be made available by the market. 
2. General Waiver Authority 
Section 211(o)(7)(A) of the CAA 
provides that EPA, in consultation with 
the Secretary of Agriculture and the Secretary of Energy, may waive the applicable volumes specified in 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 his own motion. Such a waiver must be based on a determination by the Administrator, after public notice and opportunity for comment that: (1) Implementation of the requirement would severely harm the economy or the environment of a State, a region, or the United States; or (2) there is an inadequate domestic supply. 
EPA received comments requesting 
that EPA should use the general waiver authority to further reduce volumes under findings of inadequate domestic supply and/or severe harm to the economy or environment, as well as comments to the contrary. Based on our review of the comments and updated data, and consistent with EPA’s rationale and decisions in setting the 2019 standards, we decline to exercise our discretion to reduce volumes under the general waiver authority. Further discussion of these issues is found in the Response To Comments (‘‘RTC’’) document.

B. Severability 
The various portions of this rule are 
severable. Specifically, the following portions are severable from each other: The percentage standards for 2020 (described in Section VII); the 2021 BBD volume requirement (Section VI); the administrative actions (Section VIII); and the regulatory amendments (Section IX). In addition, each of the regulatory amendments is severable from the other regulatory amendments. If any of the above portions is set aside by a reviewing court, we intend the remainder of this action to remain effective. For instance, if a reviewing court sets aside one of the regulatory amendments, we intend for the 2020 percentage standards to go into effect.

15CAA section 211(o)(5) requires that EPA 
establish a credit program as part of its RFS 
regulations, and that the credits be valid for obligated parties to show compliance for 12 months as of the date of generation. EPA implemented this requirement through the use of RINs, which can be used to demonstrate compliance for the year in which they are generated or the subsequent compliance year. Obligated parties can obtain more RINs than they need in a given compliance year, allowing them to ‘‘carry over’’ these excess RINs for use in the subsequent compliance year, although our regulations limit the use of these carryover RINs to 20 percent of the obligated party’s RVO. For the bank of carryover RINs to be preserved from one year to the next, individual carryover RINs are used for compliance before they expire and are essentially replaced with newer vintage RINs that are then held for use in the next year. For example, vintage 2018 carryover RINs must be used for compliance in 2019, or they will expire. However, vintage 2019 RINs can then be ‘‘banked’’ for use in 2020.

reference to all of the benefits that are provided by a sufficient bank of carryover RINs.

number of carryover RINs currently available can be found in the memorandum, ‘‘Carryover RIN Bank Calculations for 2020 Final Rule,’’ available in the docket.

exemptions (SREs) granted and the volume of RINs not required to be retired as a result of those exemptions can be found at: https://www.epa.gov/ fuels-registration-reporting-and-compliance-help/ rfs-small-refinery-exemptions. 
25See 40 CFR 80.1427(a)(5). 2013 through 2019, we have also 
considered the availability and role of carryover RINs in setting the cellulosic biofuel, advanced biofuel, and total renewable fuel volume requirements for 
2020. Neither the statute nor EPA regulations specify how or whether EPA should consider the availability of carryover RINs in exercising our statutory authorities.
15As noted in the 
context of the rules establishing the RFS standards for 2014 through 2019, we believe that a bank of carryover RINs is extremely important in providing obligated parties compliance flexibility in the face of substantial uncertainties in the transportation fuel marketplace, and in providing a liquid and well- functioning RIN market upon which success of the entire program depends.
16 
Carryover RINs provide flexibility in the face of a variety of unforeseeable circumstances that could limit the availability of RINs and reduce spikes in compliance costs, including weather- related damage to renewable fuel feedstocks and other circumstances potentially affecting the production and distribution of renewable fuel. On the other hand, carryover RINs can be used for compliance purposes, and in the context of the 2013 RFS rulemaking we noted that an abundance of carryover RINs available in that year, together with possible increases in renewable fuel production and import, justified maintaining the advanced and total renewable fuel volume requirements for that year at the levels specified in the statute.
17In general, we have authority 
to consider the size of the carryover RIN bank in deciding whether and to what extent to exercise any of our discretionary waiver authorities.
18 
EPA’s approach to the consideration of 
carryover RINs in exercising our cellulosic waiver authority was affirmed in Monroe Energy and ACE.
19 
The RIN system was established in 
accordance with CAA section 211(o)(5), which authorizes the generation of credits by any person who refines, blends, or imports renewable fuel in excess of the requirements of the statute.
20In the RFS1 and RFS2 
rulemakings, we also established a 20 percent rollover cap on the amount of an obligated party’s RVO that can be met using previous-year RINs.
21In 
implementing the RFS program, we have observed that an adequate carryover RIN bank serves to make the RIN market liquid wherein RINs are freely traded in an open market making them readily available and accessible to those obligated parties who need them for compliance at prices established by that open market. Just as the economy as a whole functions best when individuals and businesses prudently plan for unforeseen events by maintaining inventories and reserve money accounts, we believe that the RFS program functions best when sufficient carryover RINs are held in reserve for potential use by the RIN holders themselves, or for possible sale to others that may not have established their own carryover RIN reserves. Were there to be too few RINs in reserve, then even minor disruptions causing shortfalls in renewable fuel production 
or distribution, or higher than expected transportation fuel demand (requiring greater volumes of renewable fuel to comply with the percentage standards that apply to all volumes of transportation fuel, including the unexpected volumes) could lead to the need for a new waiver of the standards and higher compliance costs, undermining the market certainty so critical to the RFS program. Moreover, a significant drawdown of the carryover RIN bank leading to a scarcity of RINs may stop the market from functioning in an efficient manner (i.e., one in which 
there are a sufficient number of reasonably available RINs for obligated parties seeking to purchase them), even where the market overall could satisfy the standards. For all of these reasons, the collective carryover RIN bank provides a necessary programmatic buffer that both facilitates individual compliance, provides for smooth overall functioning of the program, and is consistent with the statutory provision allowing for the generation and use of credits.
22 
1. Carryover RIN Bank Size 
We estimate that there are currently 
approximately 3.48 billion total carryover RINs available, an increase of 1.29 billion RINs from the previous estimate of 2.19 billion total carryover RINs in the July 29 proposal.
23We also 
estimate that there are currently approximately 680 million advanced carryover RINs available (which are a subset of the 3.48 billion total carryover RINs), an increase of 290 million RINs from the previous estimate in the July 29 proposal. This increase in the carryover RIN bank is primarily the result of the millions of RINs that were unretired by small refineries that were granted hardship exemptions after the July 29 proposal.
24These volumes of 
carryover RINs are approximately 17 percent of the 2020 total renewable fuel volume requirement and 13 percent of the 2020 advanced biofuel volume requirement, which are less than the 20 percent maximum limit permitted by the RFS regulations to be carried over for use in complying with the 2020 standards.
25 
However, there remains considerable 
uncertainty surrounding the ultimate size of the carryover RIN bank available for compliance with the 2020 standards for several reasons, including the possibility of additional small refinery exemptions, higher or lower than expected transportation fuel demand (requiring greater or lower volumes of renewable fuel to comply with the percentage standards that apply to all

26In their comments on the 2020 NPRM, parties 
generally expressed two opposing points of view. Commenters representing obligated parties 
supported EPA’s proposed decision to not assume a drawdown in the bank of carryover RINs in determining the appropriate volume requirements, reiterating the importance of maintaining the carryover RIN bank in order to provide obligated parties with necessary compliance flexibilities, better market trading liquidity, and a cushion against future program uncertainty. Commenters representing renewable fuel producers, however, stated that not accounting for carryover RINs goes against Congressional intent of the RFS program to increase renewable fuel volumes every year and deters investment in cellulosic and advanced biofuels. A full description of comments received, and our detailed responses to them, is available in the RTC document in the docket. 
27The majority of the cellulosic RINs generated 
for CNG/LNG are sourced from biogas from 
landfills; however, the biogas may come from a variety of sources including municipal wastewater treatment facility digesters, agricultural digesters, 
separated municipal solid waste (MSW) digesters, and the cellulosic components of biomass processed in other waste digesters. volumes of transportation fuel), and the 
impact of 2019 RFS compliance on the bank of carryover RINs. In addition, we note that there have been enforcement actions in past years that have resulted in the retirement of carryover RINs to make up for the generation and use of invalid RINs and/or the failure to retire RINs for exported renewable fuel. Future enforcement actions could have similar results and require that obligated parties and/or renewable fuel exporters settle past enforcement-related obligations in addition to complying with the annual standards, thereby potentially creating demand for RINs greater than can be accommodated through actual renewable fuel blending in 2020. In light of these uncertainties, the net result could be a bank of total carryover RINs larger or smaller than 17 percent of the 2020 total renewable fuel volume requirement, and a bank of advanced carryover RINs larger or smaller than 13 percent of the 2020 advanced biofuel volume requirement. 
2. EPA’s Decision Regarding the 
Treatment of Carryover RINs 
We have evaluated the volume of 
carryover RINs currently available and considered whether it would justify an intentional drawdown of the carryover RIN bank in setting the 2020 volume requirements. We also carefully considered the comments received, including comments on the role of carryover RINs under our waiver 
authorities and the policy implications of our decision.
26For the reasons described throughout Section II.C, we 
do not believe we should intentionally draw down the carryover RIN bank in setting the 2020 volumes. The current bank of carryover RINs provides an important and necessary programmatic and cost spike buffer that will both facilitate individual compliance and provide for smooth overall functioning of the program. We believe that a balanced consideration of the possible role of carryover RINs in achieving the statutory volumes for cellulosic biofuel, advanced biofuel, and total renewable fuel, versus maintaining an adequate bank of carryover RINs for important programmatic functions, is appropriate when EPA exercises its discretion under its statutory authorities, and that the statute does not specify the extent to which EPA should require a drawdown in the bank of carryover RINs when it exercises its waiver authorities. Therefore, for the reasons noted above and consistent with the approach we took in the rules establishing the RFS standards for 2014 through 2019, we have decided to maintain our proposed approach and are not setting the 2020 
volume requirements at levels that would envision an intentional drawdown in the bank of carryover RINs. We note that we may or may not take a similar approach in future years; we will assess the situation on a case- by-case basis going forward and take into account the size of the carryover RIN bank in the future and any lessons learned from implementing past rules. 
III. Cellulosic Biofuel Volume for 2020 
In the past several years, production 
of cellulosic biofuel has continued to 
increase. Cellulosic biofuel production reached record levels in 2018, driven largely by CNG and LNG derived from biogas.
27The projected volume of 
cellulosic biofuel production in 2019 is even higher that the volume produced in 2018. Production of liquid cellulosic biofuel has also increased in recent years, even as the total production of liquid cellulosic biofuels remains much smaller than the production volumes of CNG and LNG derived from biogas (see Figure III–1). This section describes our assessment of the volume of qualifying cellulosic biofuel that we project will be produced or imported into the U.S. in 2020, and some of the uncertainties associated with those volumes.

Appeals for the District of Columbia Circuit 
evaluated this requirement in API v. EPA, 706 F.3d 
474, 479–480 (D.C. Cir. 2013), in the context of a challenge to the 2012 cellulosic biofuel standard. The Court stated that in projecting potentially available volumes of cellulosic biofuel EPA must apply an ‘‘outcome-neutral methodology’’ aimed at providing a prediction of ‘‘what will actually happen.’’ Id. at 480, 479. The Court also determined 
that Congress did not require ‘‘slavish adherence by EPA to the EIA estimate’’ and that EPA could ‘‘read the phrase ‘based on’ as requiring great respect but allowing deviation consistent with that respect.’’ In addition, EPA has consistently interpreted the term ‘‘projected volume of cellulosic biofuel production’’ in CAA section 211(o)(7)(D)(i) to include volumes of cellulosic biofuel likely to be made available in the U.S., including from both domestic production 
Continued 
In order to project the volume of 
cellulosic biofuel production in 2020, 
we considered numerous factors, 
including EIA’s projection of cellulosic biofuel production in 2020, the accuracy of the methodologies used to project cellulosic biofuel production in previous years, data reported to EPA through EMTS, and information we collected through meetings with representatives of facilities that have produced or have the potential to produce qualifying volumes of cellulosic biofuel in 2020. 
There are two main elements to the 
cellulosic biofuel production projection: Liquid cellulosic biofuel and CNG/LNG derived from biogas. To project the range of potential production volumes of liquid cellulosic biofuel we used the same general methodology as the methodology used in the 2018 and 2019 final rules. We have adjusted the percentile values used to select a point estimate within a projected production range for each group of companies based on updated information (through September 2019) with the objective of improving the accuracy of the projections. To project the production of cellulosic biofuel RINs for CNG/LNG derived from biogas, we used the same general year-over-year growth rate methodology as in the 2018 and 2019 final rules, with updated RIN generation data through September 2019. This 
methodology reflects the mature status of this industry, the large number of facilities registered to generate cellulosic biofuel RINs from these fuels, and EPA’s continued attempts to refine its methodology to yield estimates that are as accurate as possible. This methodology is an improvement on the methodology that EPA used to project cellulosic biofuel production for CNG/ LNG derived from biogas in the 2017 and previous years (see Section III.B for a further discussion of the accuracy of EPA’s methodology in previous years). The methodologies used to project the production of liquid cellulosic biofuels and cellulosic CNG/LNG derived from biogas are described in more detail in Sections III.D–1 and III.D–2. 
The balance of this section is 
organized as follows. Section III.A provides a brief description of the statutory requirements. Section III.B reviews the accuracy of EPA’s projections in prior years, and also discusses the companies EPA assessed in the process of projecting qualifying 
cellulosic biofuel production in the U.S. Section III.C discusses EIA’s projection of cellulosic biofuel production in 2020. Section III.D discusses the methodologies used by EPA to project cellulosic biofuel production in 2020 and the resulting projection of 0.59 
billion ethanol-equivalent gallons. 
A. Statutory Requirements 
CAA section 211(o)(2)(B)(i)(III) states 
the statutory volume targets for 
cellulosic biofuel. The volume of cellulosic biofuel specified in the statute for 2020 is 10.5 billion gallons. The statute provides that if EPA determines, based on a letter provided to the EPA by EIA, that the projected volume of cellulosic biofuel production in a given year is less than the statutory volume, then EPA shall reduce the applicable volume of cellulosic biofuel to the projected volume available during that calendar year.

interpretation is consistent with the statutory direction to establish the cellulosic volume at the ‘‘projected volume available.’’ We do not believe it would be reasonable to include in the projection all cellulosic biofuel produced throughout the world, regardless of likelihood of import to the U.S., since volumes that are not imported would not be 
available to obligated parties for compliance and including them in the projection would render the resulting volume requirement and percentage standards unachievable through the use of cellulosic biofuel RINs. 
29CAA section 211(o)(7)(D)(i). 30See CAA section 211(o)(7)(D)(ii); 40 CFR 
80.1456. 
31EPA only projected cellulosic biofuel 
production for the final three months of 2015, since 
data on the availability of cellulosic biofuel RINs (D3+D7) for the first nine months of the year were 
available at the time the analyses were completed for the final rule. In addition, if EPA reduces the 
required volume of cellulosic biofuel 
below the level specified in the statute, we may reduce the applicable volumes of advanced biofuels and total renewable fuel by the same or a lesser volume,
29and we are also required to 
make cellulosic waiver credits available.
30Our consideration of the 
2020 volume requirements for advanced 
biofuel and total renewable fuel is presented in Section IV. 
B. Cellulosic Biofuel Industry 
Assessment 
In this section, we first explain our 
general approach to assessing facilities or groups of facilities (which we collectively refer to as ‘‘facilities’’) that have the potential to produce cellulosic biofuel in 2020. We then review the accuracy of EPA’s projections in prior years. Next, we discuss the criteria used to determine whether to include potential domestic and foreign sources of cellulosic biofuel in our projection for 2020. Finally, we provide a summary table of all facilities that we expect to produce cellulosic biofuel in 2020. 
In order to project cellulosic biofuel 
production for 2020, we have tracked the progress of a number of potential cellulosic biofuel production facilities, located both in the U.S. and in foreign countries. We considered a number of factors, including EIA’s projection of cellulosic biofuel production in 2020, information from EMTS, the registration 
status of potential biofuel production facilities as cellulosic biofuel producers in the RFS program, publicly available information (including press releases and news reports), and information provided by representatives of potential cellulosic biofuel producers. As discussed in greater detail in Section III.D.1, our projection of liquid cellulosic biofuel is based on a facility- by-facility assessment of each of the likely sources of cellulosic biofuel in 2020, while our projection of CNG/LNG derived from biogas is based on an industry-wide assessment. To make a determination of which facilities are most likely to produce liquid cellulosic biofuel and generate cellulosic biofuel RINs in 2020, each potential producer of liquid cellulosic biofuel was investigated further to determine the current status of its facilities and its likely cellulosic biofuel production and RIN generation volumes for 2020. Both in our discussions with representatives of individual companies and as part of our internal evaluation process, we gathered and analyzed information 
including, but not limited to, the funding status of these facilities, current status of the production technologies, anticipated construction and production ramp-up periods, facility registration status, and annual fuel production and RIN generation targets. 1. Review of EPA’s Projection of 
Cellulosic Biofuel in Previous Years 
As an initial matter, it is useful to 
review the accuracy of EPA’s past cellulosic biofuel projections. The record of actual cellulosic biofuel production, including both cellulosic biofuel (which generate D3 RINs) and cellulosic diesel (which generate D7 RINs), and EPA’s projected production volumes from 2015–2019 are shown in Table III.B–1. These data indicate that EPA’s projection was lower than the actual number of cellulosic RINs made available in 2015,
31higher than the 
actual number of RINs made available in 2016 and 2017, and lower than the actual number of RINs made available in 2018. Based on our current projection of cellulosic biofuel production for 2019 based on data through September 2019, EPA’s projection of cellulosic biofuel in 2019 also appears likely to be lower than actual RIN generation in 2019. The fact that the projections made using this methodology have been somewhat inaccurate, under-estimating the actual number of RINs made available in 2015, 2018, and likely 2019, and over- estimating in 2016 and 2017, reflects the inherent difficulty with projecting cellulosic biofuel production. It also emphasizes the importance of continuing to make refinements to our projection methodology in order to make our projections more accurate.

aAs noted in Section III.A. above, EPA has consistently interpreted the term ‘‘projected volume of cellulosic biofuel production’’ to include vol-
umes of cellulosic biofuel likely to be made available in the U.S., including from both domestic production and imports. The volumes in this table 
therefore include both domestic production of cellulosic biofuel and imported cellulosic biofuel. 
bProjected volumes for 2015 and 2016 can be found in the 2014–2016 Final Rule (80 FR 77506, 77508, December 14, 2015); projected vol-
umes for 2017 can be found in the 2017 Final Rule (81 FR 89760, December 12, 2016); projected volumes for 2018 can be found in the 2018 Final Rule (82 FR 58503, December 12, 2017); projected volumes for 2019 can be found in the 2019 Final Rule (83 FR 63704, December 11, 2018). 
cActual production volumes are the total number of RINs generated minus the number of RINs retired for reasons other than compliance with 
the annual standards, based on EMTS data. 
dTotal cellulosic biofuel may not be precisely equal to the sum of liquid cellulosic biofuel and CNG/LNG derived from biogas due to rounding. 
eProjected and actual volumes for 2015 represent only the final 3 months of 2015 (October–December) as EPA used actual RIN gener ation 
data for the first 9 months of the year.

32We note, however, that because the projected 
volume of liquid cellulosic biofuel in each year was 
very small relative to the total volume of cellulosic biofuel, these over-projections had a minimal impact on the accuracy of our projections of cellulosic biofuel for each of these years. 
3382 FR 58486 (December 12, 2017). 34To project the volume of CNG/LNG derived 
from biogas in 2020, we multiply the number of 
2018 RINs generated for these fuels and available to be used for compliance with the annual standards by the calculated growth rate to project 
production of these fuels in 2019 and then multiply the resulting number by the growth rate again to project the production of these fuels in 2020. 35For a further discussion of EPA’s decision to 
focus on commercial scale facilities, rather than R&D and pilot scale facilities, see the 2019 proposed rule (83 FR 32031, July 10, 2018). 
36According to data from EMTS, the average 
price for a 2019 cellulosic biofuel RINs sold in 2019 (through September 2019) was $1.30. Alternatively, obligated parties can satisfy their cellulosic biofuel obligations by purchasing an advanced (or biomass- based diesel) RIN and a cellulosic waiver credit. The average price for a 2019 advanced biofuel RINs sold in 2019 (through September 2019) was $0.43 while the price for a 2019 cellulosic waiver credit is $1.77 (EPA–420–B–18–052). 
37The only known exception was a small volume 
of fuel produced at a demonstration scale facility exported to be used for promotional purposes. fActual production in 2019 is a projection based on actual data from January–September 2019 and a projection of likely production for Octo-
ber–December 2019. 
EPA’s projections of liquid cellulosic 
biofuel were higher than the actual 
volume of liquid cellulosic biofuel produced each year from 2015 to 2018.
32Depending on liquid cellulosic 
biofuel production in the last 3 months or 2019, our projection for 2019 may ultimately be an over-projection or under-projection of actual production, however at this time it appears likely to result in an over-projection. As a result of the over-projections in 2015–2016 (and the anticipated over-projection in 2017), and in an effort to take into account the most recent data available and make the liquid cellulosic biofuel projections more accurate, EPA adjusted our methodology in the 2018 final rule.
33The adjustments to our 
methodology adopted in the 2018 final rule resulted in a projection that is close to the volume of liquid cellulosic biofuel produced in 2018 and appear likely to result in a reasonably accurate projection in 2019. In this final rule we are again applying the approach we first used in the 2018 final rule: Using percentile values based on actual production in previous years, relative to the projected volume of liquid cellulosic biofuel in these years. We have adjusted the percentile values to project liquid cellulosic biofuel production based on actual liquid cellulosic biofuel production in 2016 to 2019. We believe that the use of the methodology (described in more detail in Section III.D.1), with the adjusted percentile values, results in a projection that reflects a neutral aim at accuracy since it accounts for expected growth in the near future by using historical data that is free of any subjective bias. 
We next turn to the projection of 
CNG/LNG derived from biogas. For 2018 and 2019, EPA used an industry-wide approach, rather than an approach that projects volumes for individual companies or facilities, to project the production of CNG/LNG derived from biogas. EPA used a facility-by-facility approach to project the production of CNG/LNG derived from biogas from 2015–2017. Notably the facility-by- facility methodology resulted in significant over-estimates of CNG/LNG production in 2016 and 2017, leading EPA to develop the alternative industry wide projection methodology first used 
in 2018. This updated approach reflects the fact that this industry is far more mature than the liquid cellulosic biofuel industry, with a far greater number of potential producers of CNG/LNG derived from biogas. In such cases, industry-wide projection methods can be more accurate than a facility-by- facility approach, especially as macro market and economic factors become more influential on total production than the success or challenges at any single facility. The industry-wide projection methodology slightly under- projected the production of CNG/LNG derived from biogas in 2018 and appears likely to slightly under-project the production of these fuels in 2019. However, the difference between the projected and actual production volume of these fuels was smaller than in 2017. 
As further described in Section 
III.D.2, EPA is again projecting production of CNG/LNG derived from biogas using the industry-wide approach. We calculate a year-over-year rate of growth in the renewable CNG/ LNG industry and apply this year-over- year growth rate to the total number of cellulosic RINs generated and available to be used for compliance with the annual standards in 2018 to estimate the production of CNG/LNG derived from biogas in 2020.
34We have applied the 
growth rate to the number of available 2018 RINs generated for CNG/LNG derived from biogas as data from this year allows us to adequately account for not only RIN generation, but also for RINs retired for reasons other than compliance with the annual standards. While more recent RIN generation data is available, the retirement of RINs for reasons other than compliance with the annual standards generally lags RIN generation, sometimes by up to a year or more. 
The production volumes of cellulosic 
biofuel in previous years also highlight that the production of CNG/LNG derived from biogas has been significantly higher than the production of liquid cellulosic biofuel in previous years. This is likely the result of a combination of several factors, including the mature state of the technology used to produce CNG/LNG derived from biogas relative to the 
technologies used to produce liquid cellulosic biofuel and the relatively low production cost of CNG/LNG derived from biogas (discussed in further detail in Section V). These factors are unlikely to change in 2020. While we project production volumes of liquid cellulosic biofuel and CNG/LNG derived from biogas separately, the actual volume of each fuel type produced may be higher or lower than projected. 
2. Potential Domestic Producers 
There are several companies and 
facilities located in the U.S. that have 
either already begun producing cellulosic biofuel for use as transportation fuel, heating oil, or jet fuel at a commercial scale,
35or are 
anticipated to be in a position to do so at some time during 2020. The RFS program provides a strong financial incentive for domestic cellulosic biofuel producers to sell any fuel they produce for domestic consumption.
36To date 
nearly all cellulosic biofuel produced in the U.S. has been used domestically
37 
and all the domestic facilities we have contacted in deriving our projections intend to produce fuel on a commercial scale for domestic consumption and plan to use approved pathways. These factors give us a high degree of confidence that cellulosic biofuel RINs will be generated for all cellulosic biofuel produced by domestic commercial scale facilities. To generate RINs, each of these facilities must be registered with EPA under the RFS program and comply with all the regulatory requirements. This includes using an approved RIN-generating pathway and verifying that their feedstocks meet the definition of renewable biomass. Most of the domestic companies and facilities considered in our assessment of potential cellulosic biofuel producers in 2019 have already successfully

38Most of the facilities listed in Table III.B.3–1 
are registered to produce cellulosic (D3 or D7) RINs 
with the exception of several of the producers of 
CNG/LNG derived from biogas and Red Rock Biofuels. EPA is unaware of any outstanding issues that would reasonably be expected to prevent these facilities from registering as cellulosic biofuel 
producers and producing qualifying cellulosic biofuel in 2020.

40‘‘Cellulosic Biofuel Producer Company 
Descriptions (May 2019),’’ memorandum from 
Dallas Burkholder to EPA Docket EPA–HQ–OAR– 2019–0136. completed facility registration, and have 
successfully generated RINs.38A brief 
description of each of the domestic companies (or group of companies for cellulosic CNG/LNG producers and the facilities using Edeniq’s technology) that EPA believes may produce commercial- scale volumes of RIN generating cellulosic biofuel by the end of 2020 can be found in a memorandum to the docket for this final rule.
39General 
information on each of these companies or group of companies considered in our projection of the potentially available volume of cellulosic biofuel in 2020 is summarized in Table III.B.4–1. 
3. Potential Foreign Sources of 
Cellulosic Biofuel 
In addition to the potential sources of 
cellulosic biofuel located in the U.S., there are several foreign cellulosic biofuel companies that may produce cellulosic biofuel in 2020. These include facilities owned and operated by Beta Renewables, Enerkem, Ensyn, GranBio, and Raizen. All of these facilities use fuel production pathways that have been approved by EPA for cellulosic RIN generation provided eligible sources of renewable feedstock are used and other regulatory requirements are satisfied. These companies would therefore be eligible to register their facilities under the RFS program and generate RINs for any qualifying fuel imported into the U.S. While these facilities may be able to generate RINs for any volumes of cellulosic biofuel they import into the U.S., demand for the cellulosic biofuels they produce is expected to be high in their own local markets. 
EPA’s projection of cellulosic biofuel 
production in 2020 includes cellulosic biofuel that is projected to be imported into the U.S. in 2020, including potential imports from all the registered foreign facilities under the RFS program. We believe that due to the strong demand for cellulosic biofuel in local markets and the time necessary for potential foreign cellulosic biofuel producers to register under the RFS program and arrange for the importation of cellulosic biofuel to the U.S., cellulosic biofuel imports from foreign facilities not currently registered to generate cellulosic biofuel RINs are generally highly unlikely in 2020. For purposes of our 2020 cellulosic biofuel projection we have excluded potential volumes from foreign cellulosic biofuel production facilities that are not currently registered under the RFS program. 
Cellulosic biofuel produced at three 
foreign facilities (Ensyn’s Renfrew facility, GranBio’s Brazilian facility, and Raizen’s Brazilian facility) generated cellulosic biofuel RINs for fuel exported to the U.S. since 2017; projected volumes from each of these facilities are included in our projection of available volumes for 2020. EPA has also included projected volume from two additional foreign facilities. These two facilities (Enerkem’s Canadian facility and Ensyn’s Port-Cartier, Quebec facility) have both completed the registration process as cellulosic biofuel producers. We believe that it is appropriate to include volume from these facilities in light of their proximity to the U.S., the proven technology used by these facilities, the volumes of cellulosic biofuel exported to the U.S. by the company in previous years (in the case of Ensyn), and the company’s stated intentions to market fuel produced at these facilities to qualifying markets in the U.S. All of the facilities included in EPA’s cellulosic biofuel projection for 2020 are listed in Table III.B.4–1. 
4. Summary of Volume Projections for 
Individual Companies 
General information on each of the 
cellulosic biofuel producers (or group of producers, for producers of CNG/LNG derived from biogas and producers of liquid cellulosic biofuel using Edeniq’s technology) that factored into our projection of cellulosic biofuel production for 2020 is shown in Table III.B.4–1. This table includes both facilities that have already generated cellulosic RINs, as well as those that have not yet generated cellulosic RINs, but are projected to do so by the end of 2020. As discussed above, we have focused on commercial-scale cellulosic biofuel production facilities. Each of these facilities (or group of facilities) is discussed further in a memorandum to the docket.

41Despite generating cellulosic RINs in previous 
years Poet-DSM’s facility has not been included in 
Table III.B.4–1 after announcing their plans to suspend commercial production at this facility. 
42The Facility Capacity is generally equal to the 
nameplate capacity provided to EPA by company representatives or found in publicly available information. Capacities are listed in physical gallons (rather than ethanol-equivalent gallons). If the facility has completed registration and the total permitted capacity is lower than the nameplate capacity, then this lower volume is used as the facility capacity. 
43Where a quarter is listed for the first production 
date EPA has assumed production begins in the 
middle month of the quarter (i.e., August for the 3rd 
quarter) for the purposes of projecting volumes. 
44For more information on these facilities see 
‘‘December 2019 Assessment of Cellulosic Biofuel Production from Biogas (2020),’’ memorandum from Dallas Burkholder to EPA Docket EPA–HQ–OAR– 2019–0136. 
45The nameplate capacity of Enerkem’s facility is 
10 million gallons per year. However, we anticipate that a portion of their feedstock will be non- biogenic municipal solid waste (MSW). RINs cannot be generated for the portion of the fuel produced from non-biogenic feedstocks. We have taken this into account in our production projection for this 
facility (See ‘‘May 2019 Liquid Cellulosic Biofuel Projections for 2020 CBI’’). 
46This date reflects the first production of ethanol 
from this facility. The facility began production of methanol in 2015.

memorandums from Dallas Burkholder to EPA Docket EPA–HQ–OAR–2019–0136. 
49Consistent with previous years, we have 
considered whether there is reason to believe any of the facilities considered as potential cellulosic biofuel producers for 2020 is likely to produce a smaller volume of cellulosic biofuel in 2020 than in the previous 12 months for which data are available. At this time, EPA is not aware of any information that would indicate lower production in 2020 from any facility considered than in the previous 12 months for which data are available. Despite generating cellulosic RINs in previous years Poet-DSM’s facility has not been included in our projection of cellulosic biofuel production in 2020 
after announcing their plans to suspend commercial production at this facility. 
50As in our 2015–2019 projections, EPA 
calculated a high end of the range for each facility (or group of facilities) based on the expected start- up date and a six-month straight-line ramp-up period. The high end of the range for each facility (or group of facilities) is equal to the value 
calculated by EPA using this methodology, or the number of RINs the producer expects to generate in 2020, whichever is lower. 
51More information on the data and methods EPA 
used to calculate each of the ranges in these tables in contained in ‘‘December 2019 Liquid Cellulosic Biofuel Projections for 2020 CBI’’ memorandum from Dallas Burkholder to EPA Docket EPA–HQ– OAR–2019–0136. We have not shown the projected ranges for each individual company. This is because the high end of the range for some of these companies are based on the company’s production projections, which they consider confidential business information (CBI). Additionally, the low end of the range for facilities that have achieved consistent commercial scale production is based on actual RIN generation data in the most recent 12 months, which is also claimed as CBI. C. Projection From the Energy 
Information Administration 
Section 211(o)(3)(A) of the CAA 
requires EIA to ‘‘provide to the Administrator of the Environmental Protection Agency an estimate, with respect to the following calendar year, of the volumes of transportation fuel, biomass-based diesel, and cellulosic biofuel projected to be sold or introduced into commerce in the United States.’’ EIA provided these estimates to EPA on October 9, 2019.
47With regard 
to domestically produced cellulosic ethanol, the EIA estimated that the available volume in 2020 would be 7 million gallons. In its letter, EIA did not identify the facilities on which their estimate of liquid cellulosic biofuel production was based. EIA did, however, indicate in the letter that it only included domestic production of cellulosic ethanol in their projections. These EIA projections, therefore, do not 
include cellulosic biofuel produced by foreign entities and imported into the U.S., nor estimates of cellulosic diesel, cellulosic heating oil or CNG/LNG produced from biogas, which together represent approximately 99 percent of our projected cellulosic biofuel volume for 2020. When limiting the scope of our projection to the companies assessed by 
EIA, we note that our volume projections are similar. EPA projects approximately 5 million gallons of cellulosic ethanol will be produced domestically in 2020. 
D. Cellulosic Biofuel Volume for 2020 1. Liquid Cellulosic Biofuel 
For our 2020 liquid cellulosic biofuel 
projection, we use the same general 
approach as we have in projecting these volumes in previous years. We begin by first categorizing potential liquid cellulosic biofuel producers in 2020 according to whether or not they have achieved consistent commercial scale production of cellulosic biofuel to date. We refer to these facilities as consistent producers and new producers, respectively. Next, we define a range of likely production volumes for 2020 for each group of companies. Finally, we 
use a percentile value to project from the established range a single projected production volume for each group of companies in 2020. As in the 2018 and 2019 final rules, we calculated percentile values for each group of companies based on the past performance of each group relative to our projected production ranges. This methodology is briefly described in this 
section and is described in detail in memoranda to the docket.
48 
We first separate the list of potential 
producers of cellulosic biofuel (listed in Table III.B.4–1) into two groups according to whether the facilities have achieved consistent commercial-scale production and cellulosic biofuel RIN generation. We next defined a range of likely production volumes for each group of potential cellulosic biofuel producers. The low end of the range for each group of producers reflects actual RIN generation data over the last 12 months for which data were available at the time our technical assessment was completed (October 2018–September 2019).
49For potential producers that 
have not yet generated any cellulosic RINs, the low end of the range is zero. For the high end of the range, we considered a variety of factors, including the expected start-up date and ramp-up period, facility capacity, and the number of RINs the producer expects to generate in 2020.
50The 
projected range for each group of companies is shown in Tables III.D.1–1 and III.D.1–2.

52To calculate the percentile value that would 
have resulted in a projection equal to actual 
production for 2019 we projected actual liquid cellulosic biofuel production for 2019 using data through September 2019 and an updated projection of liquid cellulosic biofuel production for October– December 2019. 
53Actual production is calculated by subtracting 
RINs retired for any reason other than compliance with the RFS standards from the total number of cellulosic RINs generated. 
54Companies characterized as new producers in 
the 2014–2016, 2017, 2018, and 2019 final rules 
were as follows: Abengoa (2016), CoolPlanet (2016), DuPont (2016, 2017), Edeniq (2016, 2017), Enerkem 
(2018, 2019), Ensyn Port Cartier (2018, 2019), GranBio (2016, 2017), IneosBio (2016), and Poet (2016, 2017). 
55Companies characterized as consistent 
producers in the 2014–2016, 2017, 2018, and 2019 final rules were as follows: Edeniq Active Facilities (2018, 2019), Ensyn Renfrew (2016–2019), GranBio (2018, 2019), Poet (2018, 2019), Quad County Corn Processors/Syngenta (2016–2019), and Raizen (2019).

percentile values used in this final rule see 
‘‘Calculating the Percentile Values Used to Project Liquid Cellulosic Biofuel Production for 2020 
FRM,’’ available in EPA docket EPA–HQ–OAR– 2019–0136. 
57EPA used a similar projection methodology for 
2015 as in 2016–2018, however we only projected cellulosic biofuel production volume for the final 3 months of the year, as actual production data were available for the first 9 months. We do not believe it is appropriate to consider data from a year 
for which 9 months of the data were known at the time the projection was made in determining the percentile values used to project volume over a full year. TABLE III.D.1–2—2020 P RODUCTION RANGES FOR CONSISTENT PRODUCERS OF LIQUID CELLULOSIC BIOFUEL

After defining likely production 
ranges for each group of companies, we 
next determined the percentile values to use in projecting a production volume for each group of companies. We calculated the percentile values using actual production data from 2016 through 2019.
52The first full year in which EPA used the current 
methodology for developing the range potential production volumes for each company was 2016, while 2019 is the most recent year for which we have data. 
For each group of companies and for 
each year from 2016–2019, Table III.C.1–3 shows the projected ranges for 
liquid cellulosic biofuel production (from the 2014–16, 2017, 2018, and 2019 final rules), actual production, and the percentile values that would have resulted in a projection equal to the actual production volume.

racy of our projections for each year from 2016–2019, rather than allowing the average percentiles calculated to be dominated by years with greater projected volumes. 
Based upon this analysis, EPA has 
projected cellulosic biofuel production 
from new producers at the 9th percentile of the calculated range and from consistent producers at the 10th percentile.
56These percentiles are 
calculated by averaging the percentiles that would have produced cellulosic biofuel projections equal to the volumes produced by each group of companies in 2016–2019. Prior to 2016, EPA used different methodologies to project available volumes of cellulosic biofuel and thus believes it inappropriate to calculate percentile values based on projections from those years.
57 We then used these percentile values, 
together with the ranges determined for 
each group of companies discussed above, to project a volume for each group of companies in 2020. These calculations are summarized in Table III.D.1–4.

58Historically RIN generation for CNG/LNG 
derived from biogas has increased each year. It is 
possible, however, that RIN generation for these fuels in the most recent 12 months for which data are available could be lower than the preceding 12 months. We believe our methodology accounts for this possibility. In such a case, the calculated rate of growth would be negative. 
59This growth rate is higher than the growth rates 
used to project CNG/LNG volumes in the 2019 final rule (29.0%, see 83 FR 63717, December 11, 2018) and the 2018 final rule (21.6%, see 82 FR 58502, December 12, 2017). 
60Further detail on the data used to calculate 
each of these numbers in this table, as well as the 
projected volume of CNG/LNG derived from biogas used as transportation fuel in 2020 can be found in 
‘‘December 2019 Assessment of Cellulosic Biofuel Production from Biogas (2020)’’ memorandum from Dallas Burkholder to EPA Docket PA–HQ–OAR– 2019–0136. 
61To calculate this value, EPA multiplied the 
number of 2018 RINs generated and available for compliance for CNG/LNG derived from biogas (303.2 million), by 1.379 (representing a 37.9 percent year-over-year increase) to project production of CNG/LNG in 2019, and multiplied this number (418.2 million RINs) by 1.379 again to project production of CNG/LNG in 2020. 
62EPA is aware of several estimates for the 
quantity of CNG/LNG that will be used as 
transportation fuel in 2020. As discussed in a paper prepared by Bates White for the Coalition for 
Renewable Gas (‘‘Renewable Natural Gas Supply and Demand for Transportation.’’ Bates White Economic Consulting, April 5, 2019) these estimates 
range from nearly 600 million ethanol-equivalent gallons in 2020 (February 2019 STEO) to over 1.5 billion gallons (Fuels Institute—US Share). As discussed in further detail in a memorandum to the docket (‘‘December 2019 Assessment of Cellulosic Biofuel Production from Biogas (2020)’’ memorandum from Dallas Burkholder to EPA Docket EPA–HQ–OAR–2019–0136) we believe the higher projections are likely to be more accurate. Thus, the volume of CNG/LNG used as transportation fuel would not appear to constrain the number of RINs generated for this fuel in 2020.

2. CNG/LNG Derived From Biogas 
For 2020, EPA is using the same 
industry wide projection approach as 
used for 2018 and 2019 based on a year- over-year growth rate to project production of CNG/LNG derived from biogas used as transportation fuel.
58 
EPA calculated the year-over-year 
growth rate in CNG/LNG derived from biogas by comparing RIN generation from October 2018 to September 2019 (the most recent 12 months for which data are available) to RIN generation in the 12 months that immediately precede 
this time period (October 2017 to September 2018). The growth rate calculated using this data is 37.9 percent.
59These RIN generation 
volumes are shown in Table III.D.2–1.

EPA then applied this 37.9 percent 
year-over-year growth rate to the total 
number of 2018 cellulosic RINs generated and available for compliance for CNG/LNG. This methodology results in a projection of 576.8 million gallons of CNG/LNG derived from biogas in 2020. In this rule, as in the 2018 and 2019 final rules, we are again applying the calculated year-over-year rate of growth to the volume of CNG/LNG actually supplied in 2018 (taking into account actual RIN generation as well as RINs retired for reasons other than compliance with the annual volume obligations) to provide an updated projection of the production of these fuels in 2019, and then applying the rate of growth to this updated 2019 projection to project the production of these fuels in 2020.
61 We believe that projecting the 
production of CNG/LNG derived from biogas in this manner appropriately takes into consideration the actual recent rate of growth of this industry, and that this growth rate accounts for both the potential for future growth and the challenges associated with increasing RIN generation from these fuels in future years. This methodology may not be appropriate to use as the projected volume of CNG/LNG derived from biogas approaches the total volume of CNG/LNG that is used as transportation fuel, as RINs can be generated only for CNG/LNG used as transportation fuel. We do not believe that this is yet a constraint as our projection for 2020 is below the total volume of CNG/LNG that is currently used as transportation fuel.
62 3. Total Cellulosic Biofuel in 2020 
After projecting production of 
cellulosic biofuel from liquid cellulosic 
biofuel production facilities and producers of CNG/LNG derived from biogas, EPA combined these projections to project total cellulosic biofuel production for 2020. These projections are shown in Table III.D.3–1. Using the methodologies described in this section, we project that 0.59 billion ethanol- equivalent gallons of qualifying 
cellulosic biofuel will be produced in 2020. We believe that projecting overall production in 2020 in the manner described above results in a neutral estimate (neither biased to produce a projection that is too high nor too low) of likely cellulosic biofuel production in 2020.

aRounded to the nearest million gallons. 
Unlike in previous years, we have 
rounded the final projected volume of 
cellulosic biofuel to the nearest 10 million gallons as proposed. This is consistent with the volumes in the tables containing the statutory volume targets for cellulosic biofuel through 2022, which also specify volumes to no more than the nearest 10 million gallons (and in many cases only to the nearest 100 million gallons). While in previous years we have rounded the required cellulosic biofuel volume to the nearest million gallon, the projected volume of cellulosic biofuel has grown such that this level of precision is unnecessary, and likely unfounded. By rounding to the nearest 10 million gallons the total projected volume of cellulosic biofuel is affected in the most extreme case by only 5 million gallons, or approximately 1 percent of the total projected volume. The uncertainty in the projected volume of cellulosic biofuel is significantly higher than any error introduced by rounding the projected volume to the nearest 10 million gallons. 
IV. Advanced Biofuel and Total 
Renewable Fuel Volumes for 2020 
The national volume targets for 
advanced biofuel and total renewable fuel to be used under the RFS program each year through 2022 are specified in CAA section 211(o)(2)(B)(i)(I) and (II). Congress set annual renewable fuel volume targets that envisioned growth at a pace that far exceeded historical growth and, for years after 2011, prioritized that growth as occurring principally in advanced biofuels (contrary to previous growth patterns where most growth was in conventional renewable fuel). Congressional intent is evident in the fact that the implied statutory volume requirement for 
conventional renewable fuel is 15 billion gallons for all years after 2014, while the advanced biofuel volume requirements, driven largely by growth in cellulosic biofuel, continue to grow each year through 2022 to a total of 21 billion gallons. Early growth in conventional renewable fuels was expected to provide a bridge to the new, more beneficial cellulosic biofuels in 
the later years.
63 
Due to a projected shortfall in the 
availability of cellulosic biofuel, and consistent with our long-held interpretation that the cellulosic waiver authority is best interpreted to provide equal reductions to advanced biofuel and total renewable fuel volumes, we are reducing the statutory volume targets for both advanced biofuel and total renewable fuel for 2020 by the maximum amount permitted under the cellulosic waiver authority, 9.91 billion gallons. Section IV.A explains the volumetric limitation on our use of the cellulosic waiver authority to reduce advanced biofuel and total renewable fuel volumes. Section IV.B presents our technical analysis of the reasonably attainable and attainable volumes of advanced biofuel. Sections IV.C and IV.D further explain our decision to exercise the maximum discretion available under the cellulosic waiver authority to reduce advanced biofuel and total renewable fuel, respectively. 
To begin, we have evaluated the 
capabilities of the market and are making a finding that the 15.0 billion gallons specified in the statute for advanced biofuel cannot be reached in 2020. This is primarily due to the expected continued shortfall in cellulosic biofuel; production of this fuel type has consistently fallen short of the statutory targets by 90 percent or more, and as described in Section III, we project that it will fall far short of the statutory target of 10.5 billion gallons in 2020. For this and other reasons described in this section we are reducing the advanced biofuel statutory target by 9.91 billion gallons for 2020. 
In previous years when we have used 
the cellulosic waiver authority, we have determined the extent to which we should reduce advanced biofuel volumes by considering a number of different factors under the broad discretion which that authority 
provides, including: 
•The availability of advanced biofuels 
(e.g., historic data on domestic 
supply, expiration of the biodiesel 
blenders’ tax credit, potential imports of biodiesel in light of the Commerce Department’s determination on tariffs on biodiesel imports from Argentina and Indonesia, potential imports of sugarcane ethanol, and anticipated changes in the production of feedstocks for advanced biodiesel and renewable diesel) 
•The energy security and greenhouse 
gas (GHG) impacts of advanced biofuels 
•The availability of carryover RINs 
•The intent of Congress as reflected in 
the statutory volumes tables to substantially increase the use of advanced biofuels over time 
•Increased costs associated with the 
use of advanced biofuels, and 
•The increasing likelihood of adverse 
unintended impacts associated with use of advanced biofuel volumes achieved through diversion of foreign fuels or substitution of advanced feedstocks from other uses to biofuel production. 
Before the 2018 standards were set, 
the consideration of these factors led us 
to conclude that it was appropriate to set the advanced biofuel standard in a manner that would allow the partial backfilling of missing cellulosic volumes with non-cellulosic advanced biofuels.
64In the 2018 and 2019 
standards final rules, we concluded that partial backfilling of missing cellulosic biofuel volumes with advanced biofuel was not warranted, primarily due to a shortfall in reasonably attainable volumes of advanced biofuels, high costs, the potential for feedstock switching and/or foreign fuel diversion which could compromise GHG benefits and disrupt markets, and an interest in preserving the existing carryover RIN bank.

67CAA section 211(o)(7)(D)(i). 6883 FR 63704, 63721 (December 11, 2019). 
69Our consideration of ‘‘reasonably attainable’’ 
volumes is not intended to imply that ‘‘attainable’’ 
volumes are unreasonable or otherwise inappropriate. As we explain in this section, we 
believe that an advanced biofuel volume of 5.09 billion gallons, although not reasonably attainable, is attainable, and that establishing such volume is an appropriate exercise of our cellulosic waiver authority. 7081 FR 89762 (December 12, 2016). The 
maximum achievable volume may be relevant to 
our consideration of whether to exercise the general waiver authority on the basis of inadequate domestic supply. However, for 2020, we have determined that after exercising our cellulosic waiver authority to the full extent permitted, the resulting advanced biofuel volume is attainable. Therefore, further reductions using the general waiver authority on the basis of inadequate domestic supply are not necessary. 
71The statute directs EPA to lower the cellulosic 
biofuel volume to the projected production level where that level falls short of the statutory volume. Under API v. EPA, 706 F.3d 474, 479–80 (D.C. Cir. 
2013), we must project this production level with neutral aim at accuracy, that is, make a technical determination about the market’s ability to produce cellulosic biofuels. By contrast, the discretionary portion of the cellulosic waiver authority does not explicitly require EPA to project the availability of advanced biofuels, but instead confers broad discretion on EPA. Moreover, while we have chosen to estimate reasonably attainable and attainable volumes of advanced biofuel, these volumes do not equate to projected production alone. Rather, in exercising the discretionary portion of the cellulosic waiver authority, we also consider a range of policy 
factors—such as costs, greenhouse gas emissions, 
Continued For 2020, we have determined that 
the concerns surrounding partial 
backfilling of missing cellulosic biofuel with advanced biofuel remain valid. As a result, we are reducing the statutory volume target for advanced biofuel by the same amount as the reduction in cellulosic biofuel. This results in the non-cellulosic component of the advanced biofuel volume requirement being equal to 4.50 billion gallons in 2020, which is the same as the implied statutory volume requirement for non- cellulosic advanced biofuel for 2020. 
The impact of our exercise of the 
cellulosic waiver authority is that after waiving the statutory volume target for cellulosic biofuel down to the projected available level, and then reducing the statutory volume target for advanced biofuel by the same amount, the 
resulting volume requirement for advanced biofuel for 2020 is 5.09 billion gallons. This volume requirement is 170 
million gallons more than the applicable volume used to derive the 2019 percentage standard. Furthermore, after applying the same reduction to the statutory volume target for total renewable fuel, the volume requirement for total renewable fuel is also 170 
million gallons more than the applicable volume used to derive the 2019 percentage standard. These increases are entirely attributable to a 170 million gallon increase in the cellulosic biofuel volume requirement. The implied volumes of non-cellulosic advanced biofuel and conventional renewable fuel will remain the same as in 2019 at 4.5 and 15 billion gallons respectively. 
A. Volumetric Limitation on Use of the 
Cellulosic Waiver Authority 
As described in Section II.A, when 
making reductions in advanced biofuel and total renewable fuel under the 
cellulosic waiver authority, the statute limits those reductions to no more than the reduction in cellulosic biofuel. As described in Section III.C, we are establishing a 2020 applicable volume for cellulosic biofuel of 590 million gallons, representing a reduction of 9,910 million gallons from the statutory target of 10,500 million gallons. As a result, 9,910 million gallons is the maximum volume reduction for advanced biofuel and total renewable fuel that is permissible using the cellulosic waiver authority. Use of the cellulosic waiver authority to this maximum extent would result in volumes of 5.09 and 20.09 billion gallons for advanced biofuel and total renewable fuel, respectively.

We are authorized under the 
cellulosic waiver authority to reduce the 
advanced biofuel and total renewable fuel volumes ‘‘by the same or a lesser’’ amount as the reduction in the cellulosic biofuel volume.
67As 
discussed in Section II.A, EPA has broad discretion in using the cellulosic waiver authority in instances where its use is authorized under the statute, since Congress did not specify factors that EPA must consider in determining whether to use the authority to reduce advanced biofuel or total renewable fuel, nor what the appropriate volume reductions (within the range permitted by statute) should be. Thus, we have the authority to set the 2020 advanced biofuel volume requirement at a level that is designed to partially backfill for the shortfall in cellulosic biofuel. However, as discussed below, we do not believe this would be appropriate for 2020. 
B. Attainable Volumes of Advanced 
Biofuel 
We have evaluated whether it would 
be appropriate to require 5.09 billion ethanol-equivalent gallons of advanced biofuel for 2020. In doing so, we have considered both attainable and reasonably attainable volumes of 
advanced biofuel to inform our exercise of the cellulosic
68waiver authority. As 
we explained in the 2019 final rule, both ‘‘reasonably attainable’’ and ‘‘attainable’’ are terms of art defined by EPA.
69Volumes described as 
‘‘reasonably attainable’’ are those that can be reached with minimal market disruptions, increased costs, reduced GHG benefits, and diversion of advanced biofuels or advanced biofuel feedstocks from existing uses. Volumes described as ‘‘attainable,’’ in contrast, are those we believe can be reached but would likely result in market disruption, higher costs, and/or reduced GHG benefits. Neither ‘‘reasonably attainable’’ nor ‘‘attainable’’ are meant to convey the ‘‘maximum achievable’’ level, which, as we explained in the 2017 final rule, we do not consider to be an appropriate target under the cellulosic waiver authority.
70Finally, 
we note that our assessments of the ‘‘reasonably attainable’’ and ‘‘attainable’’ volumes of non-cellulosic advanced biofuels are not intended to be as exacting as our projection of cellulosic biofuel production, described in Section III of this rule.

described throughout this section.

73See id. at 730–35. 740.07 + 0.05 + 2.77 × 1.55 + 0.59 = 5.00. 7583 FR 63704 (December 11, 2018). As in prior rulemakings, we begin by 
considering what volumes of advanced 
biofuels are reasonably attainable. In ACE, the Court noted that in assessing 
what volumes are ‘‘reasonably attainable,’’ EPA had considered the availability of feedstocks, domestic production capacity, imports, and market capacity to produce, distribute, and consume renewable fuel.
72These 
considerations include both demand- side and supply-side factors.
73We are 
taking a similar approach for 2020. We are establishing the advanced biofuel volume requirement at a level that takes into consideration both the benefits and drawbacks of an increase in the implied non-cellulosic advanced biofuel volume requirement, as well as the ability of the market to make such increased volumes available. 
Our individual assessments of 
reasonably attainable volumes of each type of advanced biofuel reflect this approach. As discussed in further detail in this section, we find that 70 million 
gallons of imported advanced ethanol, 50 million gallons of other advanced biofuels, and 2.77 billion gallons of advanced biodiesel and renewable diesel are reasonably attainable. Together with our projected volume of 590 million gallons of cellulosic biofuel, the sum of these volumes is 5.00 billion gallons.
74This is the volume of 
advanced biofuel that we believe is 
reasonably attainable. 
As described in Section IV.A above, 
5.09 billion gallons is the lowest level that we could set under the cellulosic waiver authority. Since the volume that we have determined to be reasonably attainable—5.00 billion gallons—is less than the lowest volume we can set under the cellulosic waiver authority, we also have considered whether the market can make more than 5.00 billion gallons of advanced biofuel, notwithstanding the potential for feedstock/fuel diversions. That is, we assess whether 5.09 billion gallons is merely ‘‘attainable,’’ as opposed to ‘‘reasonably attainable.’’ In particular, we assess whether additional volumes of advanced biodiesel and renewable diesel are attainable. We conclude that 2.83 billion gallons of advanced biodiesel and renewable diesel are attainable, notwithstanding potential feedstock/fuel diversions. This quantity of advanced biodiesel and renewable diesel, together with the cellulosic biofuel, sugarcane ethanol, and other advanced biofuels described above, will enable the market to make available 5.09 billion gallons of advanced biofuels. 
1. Imported Sugarcane Ethanol 
The predominant available source of 
advanced biofuel other than cellulosic 
biofuel and BBD has historically been imported sugarcane ethanol. Imported 
sugarcane ethanol from Brazil is the predominant form of imported ethanol and the only significant source of imported advanced ethanol. In setting the 2019 standards, we estimated that 100 million gallons of imported sugarcane ethanol would be reasonably attainable.
75This was based on a 
combination of data from recent years demonstrating relatively low import volumes and older data indicating that higher volumes were possible. We also noted the high variability in ethanol import volumes in the past (including of Brazilian sugarcane ethanol), increasing gasoline consumption in Brazil, and variability in Brazilian production of sugar as reasons that it would be inappropriate to assume that sugarcane ethanol imports would reach the much higher levels suggested by some stakeholders. 
At the time of the 2019 standards final 
rule, we used available data from a portion of 2018 to estimate that import volumes of sugarcane ethanol were likely to fall significantly below the 200 million gallons we had assumed when we set the 2018 standards. Since the 2019 final rule, new data reveals a continued trend of low imports. Specifically, import data for all of 2018 is now available and indicates that imports of sugarcane ethanol reached just 54 million gallons.

76The difference between D5 and D6 RIN prices 
can also influence the relative attractiveness to 
consumers of advanced ethanol compared to conventional ethanol. However, there has been considerable variability in this particular RIN price difference over the last few years. 
Data for 2019 through August indicate 
that advanced ethanol imports reached 
95 million gallons. While we cannot project precisely what total import volumes will be by the end of 2019, as a first approximation is may be 
reasonable to assume that the monthly rate of import is consistent throughout the year. If so, then total 2019 imports could be 143 million gallons. 
However, there is little evidence that 
the increase potentially exhibited in 2019 would continue into 2020 as there is no consistent upward or downward trend after 2013. Moreover, several factors create disincentives for increasing imports above the levels in recent years, including the E10 blendwall, the potential existence of a recurring tax credit for biodiesel and renewable diesel with which sugarcane ethanol competes within the advanced biofuel category, and the fact that imported sugarcane ethanol typically costs more than corn ethanol.
76As a result of these factors and the lower 
levels that have occurred in recent years, we believe it would be appropriate to reduce the expected volume of imported sugarcane ethanol below 100 million gallons. 
Imports of sugarcane ethanol appear 
to have stabilized in the 2014 to 2018 timeframe in comparison to previous years. The average for these years is 67 million gallons. Due to the difficulty in precisely projecting future import volumes as described further below, we believe that a rounded value of 70 million gallons would be more appropriate and thus we use 70 million gallons of imported sugarcane ethanol for the purposes of projecting reasonably attainable volumes of advanced biofuel for 2020. We believe the volume of fuel imported in previous years is a reasonable way to project the reasonably attainable volume of sugarcane ethanol in 2020. 
In the July 29 proposal, we projected 
that 60 million gallons of imported sugarcane ethanol would be available in 2020. Our revised estimate of 70 million 
gallons reflects updated data on 2018 imports as well as a more robust quantitative approach to calculating recent actual imports. 
We note that the future projection of 
imports of sugarcane ethanol is inherently imprecise and that actual imports in 2020 could be lower or higher than 70 million gallons. Factors that could affect import volumes include uncertainty in the Brazilian political climate, weather and harvests in Brazil, world ethanol demand and prices, constraints associated with the E10 blendwall in the U.S., the status of the biodiesel tax credit which affects the economic attractiveness of sugarcane ethanol’s primary competitor, world demand for and prices of sugar, and the cost of sugarcane ethanol relative to that of corn ethanol. After considering these factors, and in light of the high degree of variability in historical imports of sugarcane ethanol, we believe that 70

80No RIN-generating volumes of these other 
advanced biofuels were produced in 2018, and less than 1 million gallons total in prior years. million gallons is reasonably attainable 
for 2020.77 
2. Other Advanced Biofuel 
In addition to cellulosic biofuel, 
imported sugarcane ethanol, and advanced biodiesel and renewable diesel, there are other advanced biofuels that can be counted in the determination of reasonably attainable volumes of advanced biofuel for 2020. These other advanced biofuels include non-cellulosic CNG, naphtha, heating 
oil, and domestically produced advanced ethanol. However, the supply of these fuels has been relatively low in the last several years.

aExcludes consideration of D5 renewable diesel, as this category of renewable fuel is considered as part of biodiesel and renewable diesel as 
discussed in Section IV.B.3. 
The significant decrease after 2014 in 
CNG/LNG from biogas as advanced 
biofuel with a D code of 5 is due to the re-categorization in 2014 of landfill biogas from advanced (D code 5) to cellulosic (D code 3).
78Subsequently, 
total supply of these other advanced biofuels has exhibited no consistent trend during 2015 to 2018. The average during those four years was 54 million gallons. However, due to the high variability, and consistent with the approach we are taking for estimating volumes of imported sugarcane ethanol, we believe that this average should be rounded to the nearest 10 million gallons. As a result, we have used 50 million gallons to represent other advanced biofuels in the context of estimating attainable volumes of advanced biofuel.
79As with sugarcane 
ethanol, we have not conducted an in- depth assessment of the volume of other advanced biofuels that could be made available to the U.S. without diverting this fuel from other markets. We believe the volume of fuel supplied in previous years is a reasonable way to project the reasonably attainable volume of other advanced biofuels in 2020. 
We acknowledge that, in the July 29 
proposal, we proposed using 60 million gallons of other advanced biofuel in estimating attainable volumes of advanced biofuel. This value was based on the same data shown in Table IV.B.2–1, but using a more qualitative approach wherein 60 million gallons was deemed representative of both historical volumes and those that could be attained in 2020. For this final rule we have chosen to use a mathematical approach that is consistent with the approach we have taken for imported sugarcane ethanol, and which we believe represents a more robust methodology for making future projections. As the change in the projected 2020 volume of other advanced biofuel is very small, we do not believe this change in approach meaningfully affects the broader assessment of advanced biofuel volumes. Moreover, we note that this final action uses a volume of imported sugarcane ethanol that is 10 million gallons higher than that proposed, while simultaneously using a volume of other advanced that is 10 million gallons lower than that proposed. The net effect on projections of advanced biofuel for both of these changes combined is zero. 
We recognize that the potential exists 
for additional volumes of advanced biofuel from sources such as jet fuel, liquefied petroleum gas (LPG), butanol, and liquefied natural gas (as distinct from CNG), as well as non-cellulosic CNG from biogas produced in digesters. However, since they have been produced, if at all, in only de minimis and sporadic amounts in the past, we do not have a reasonable basis for projecting substantial volumes from these sources in 2020.

3. Biodiesel and Renewable Diesel 
Having projected the available volume 
of cellulosic biofuel, and the reasonably attainable volumes of imported sugarcane ethanol and ‘‘other’’ 
advanced biofuels, we next assess the availability of advanced biodiesel and renewable diesel by considering a wide range of factors. First, we calculate the amount of advanced biodiesel and renewable diesel that would be needed to meet the 5.09 billion ethanol- equivalent gallon advanced requirement were we to exercise our maximum discretion under the cellulosic waiver authority discussed in Section IV.A. This calculation, shown in Table IV.B.3–1, helps inform the exercise of our waiver authorities. Second, we consider the historical availability of these fuels, including the impacts of biodiesel tax policy and tariffs. Third, we consider other factors that could potentially limit the availability of these fuels including the production capacity of advanced biodiesel and renewable diesel production facilities, and the ability for the market to distribute and use these fuels. Fourth, we assess the availability of advanced feedstocks. As part of this analysis, we consider the volume of advanced biodiesel and renewable diesel that can be made available with minimal diversions of advanced feedstocks and biofuels from existing uses, i.e., the reasonably 
attainable volume of advanced biodiesel and renewable diesel. We calculate this 
volume based on our projection of growth in qualifying feedstocks and on the reasonably attainable volume calculated in the 2019 final rule. Fifth, we consider how changes to the import and export of advanced biodiesel and

81We note that we have not attempted to 
determine the maximum achievable volume of 
these fuels. While the maximum achievable volume of advanced biodiesel and renewable diesel in 2020 is likely greater than 2.83 billion gallons we do not believe it would be appropriate to require a greater volume of these fuels due to the high cost and increased likelihood of adverse unintended impacts 
associated with these fuels. 
82To calculate the volume of advanced biodiesel 
and renewable diesel that would generate the 4.37 billion RINs needed to meet the advanced biofuel volume EPA divided the 4.37 billion RINs by 1.55, which is the approximate average (weighted by the volume of these fuels expected to be produced in 
2020) of the equivalence values for biodiesel (generally 1.5) and renewable diesel (generally 1.7). 
83Throughout this section we refer to advanced 
biodiesel and renewable diesel as well as advanced biodiesel and renewable diesel feedstocks. In this context, advanced biodiesel and renewable diesel refer to any biodiesel or renewable diesel for which 
RINs can be generated that satisfy an obligated party’s advanced biofuel obligation (i.e., D4 or D5 
RINs). While cellulosic diesel (D7) can also contribute towards an obligated party’s advanced biofuel obligation, these fuels are discussed in Section III rather than in this section. An advanced biodiesel or renewable feedstock refers to any of the 
biodiesel, renewable diesel, jet fuel, and heating oil feedstocks listed in Table 1 to 40 CFR 80.1426 or in petition approvals issued pursuant to section 80.1416, that can be used to produce fuel that qualifies for D4 or D5 RINs. These feedstocks include, for example, soy bean oil; oil from annual cover crops; oil from algae grown 
photosynthetically; biogenic waste oils/fats/greases; non-food grade corn oil; camelina sativa oil; and canola/rapeseed oil (See pathways F, G, and H of Table 1 to section 80.1426). 
84From 2011 through 2018 approximately 96 
percent of all biodiesel and renewable diesel 
Continued renewable diesel could impact the 
available volume of these fuels. 
These analyses support three key 
findings. First, were EPA to exercise the cellulosic waiver authority to the maximum extent, we would require an advanced biofuel volume of 5.09 billion ethanol-equivalent gallons, of which we estimate 4.37 billion ethanol-equivalent gallons (2.83 billion actual gallons of biodiesel and renewable diesel) would be met by advanced biodiesel and renewable diesel. Second, the reasonably attainable volume of advanced biodiesel and renewable diesel, which can be achieved with minimal diversions of advanced feedstocks and biofuels (2.77 billion gallons) is slightly lower than this volume. This finding, together with the high cost of advanced biofuels, supports our decision to exercise the cellulosic waiver authority to the maximum extent 
and not to permit backfilling of missing cellulosic volumes with additional advanced biofuels. Third, 2.83 billion gallons of advanced biodiesel and renewable diesel are attainable by the market. These findings, together with additional discussions in the RTC document and docket memoranda, supports our decisions to neither 
require the use of additional volumes of advanced biofuel to backfill for the shortfall in cellulosic biofuel nor to further waive volumes under the general waiver authority.
81 
a. Volume of Advanced Biodiesel and Renewable Diesel To Achieve Advanced Biofuel Volume 
We begin by calculating the volume of 
advanced biodiesel and renewable diesel that would be needed to meet the 2020 advanced biofuel volume were EPA to exercise the cellulosic waiver authority to the maximum extent. This important benchmark informs EPA’s consideration of our waiver authorities, albeit as only one factor among many. Specifically, in past annual rules where the reasonably attainable volume of biodiesel and renewable diesel has exceeded this benchmark, as was the case in 2017 and 2018, EPA has considered whether or not to allow additional volumes of these fuels to backfill for missing cellulosic biofuel volumes. By contrast, where the reasonably attainable volume of advanced biodiesel and renewable diesel has been less than this 
benchmark, as was the case in 2019, this weighs in favor of exercising the 
cellulosic waiver authority to the maximum extent so as to minimize diversions of advanced biofuels and feedstocks and the associated harms and the need for additional volumes of high cost advanced biofuel. Relatedly, were EPA to find that volume of advanced biodiesel and renewable diesel needed to meet this benchmark is not attainable, that would weigh in favor of EPA exercising its discretion under additional waiver authorities, to the extent available, to make further reductions to the advanced biofuel volume. 
As shown in Table IV.B.3–1, were 
EPA to exercise the cellulosic waiver authority to the maximum extent, the required volume of advanced biofuel would be 5.09 billion ethanol- equivalent gallons. After subtracting from this volume the available volume 
of cellulosic biofuel and reasonably attainable volumes of imported sugarcane ethanol and ‘‘other’’ advanced biofuels, we estimate that approximately 2.83 billion gallons of advanced biodiesel and renewable diesel would be needed to meet the 2020 advanced biofuel volume.

b. Historical Supply of Biodiesel and 
Renewable Diesel 
We next consider the volumes of 
advanced biodiesel and renewable diesel supplied in previous years, as well as the impacts of biodiesel tax policy and tariffs on these volumes. A review of the volumes of advanced biodiesel and renewable diesel used in previous years is especially useful in projecting the potential availability of these fuels, since there are a number of 
complex and inter-related factors beyond simply total production capacity (including the availability of advanced biodiesel and renewable diesel feedstocks,
83the expiration of the 
biodiesel tax credit, changes to tariffs on biodiesel from Argentina and Indonesia, import and distribution infrastructure, and other market-based factors) that 
could affect the supply of advanced biodiesel and renewable diesel. While historic data and trends alone are 
insufficient to project the volumes of biodiesel and renewable diesel that could be provided in future years, historic data can serve as a useful reference in considering future volumes. 
Past experience suggests that a high 
percentage of the biodiesel and renewable diesel used in the U.S. (from both domestic production and imports) qualifies as advanced biofuel.

supplied to the U.S. (including domestically 
produced and imported biodiesel and renewable diesel) qualified as advanced biodiesel and renewable diesel (14,214 million gallons of the 14,869 million gallons) according to EMTS data. This section focuses on the availability of advanced biodiesel and renewable diesel to meet the advanced biofuel volume. For a discussion of the 
availability of all biodiesel and renewable diesel that could be used to meet the total renewable fuel volume see ‘‘Updated market impacts of biofuels in 
2020,’’ memorandum from David Korotney to docket EPA–HQ–OAR–2019–0136. 
85From 2011 through 2018 over 99.9 percent of 
all the domestically produced biodiesel and renewable diesel supplied to the U.S. qualified as advanced biodiesel and renewable diesel (12,268 
million gallons of the 12,275 million gallons) according to EMTS data. 86For this final rule EPA reviewed the data 
available in EMTS and updated historical 
renewable fuel production and RIN generation data. This updated data can be found in ‘‘Historical RIN supply as of 8–12–19,’’ memorandum from David Korotney to EPA docket EPA–HQ–OAR–2019–0136. Tables in this final rule that contain historical data (such as Tables IV.B.3–2, IV.B.3–3, VI.B.1–1 and VI.B.1–2) have been updated accordingly. previous years, biodiesel and renewable 
diesel produced in the U.S. have been almost exclusively advanced biofuel.
85 
Volumes of imported biodiesel and renewable diesel, which include both advanced and conventional biodiesel and renewable diesel, have varied significantly from year to year, as they are impacted both by domestic and foreign policies, as well as many economic factors. Production, import, export, and total volumes of advanced biodiesel and renewable diesel are 
shown in Table IV.B.3–2, while volumes of conventional biodiesel and renewable diesel are shown in the following Table IV.B.3–3.

87We note that the status of the tax credit does 
not impact our assessment of the reasonably 
attainable volume of advanced biodiesel and renewable diesel in 2020 as that assessment is primarily based on feedstock availability. The status of the tax credit could potentially affect the maximum achievable volume of these fuels, but our assessment demonstrates that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable whether or not the tax credit is renewed prospectively (or retrospectively) for 2020. 88For a further discussion of the impact of the tax 
credit on the supply of biodiesel and renewable 
diesel, see the discussion from the proposed rule (84 FR 36783, July 29, 2019). 
89‘‘Biodiesel from Argentina and Indonesia

90See ‘‘EIA Biomass-Based Diesel Import Data’’ 
available in docket EPA–HQ–OAR–2019–0136. 
9184 FR 32714 (July 9, 2019). 92The production capacity of the sub-set of 
biodiesel and renewable diesel producers that generated RINs in 2018 is approximately 2.9 billion gallons. See ‘‘Biodiesel and Renewable Diesel Registered Capacity (March 2019)’’ Memorandum from Dallas Burkholder to EPA Docket EPA–HQ– OAR–2019–0136. As we explained above, to meet an 
advanced biofuel volume of 5.09 billion 
ethanol-equivalent gallons we project that the market would supply 2.83 billion gallons of advanced biodiesel and renewable diesel. This volume (2.83 billion gallons) is approximately 90 million gallons greater than the volume of these fuels projected to be supplied in 2019 based on data through September 2019. Since 2011, the year- over-year changes in the volume of advanced biodiesel and renewable diesel used in the U.S. have varied greatly, from a low of 147 million fewer gallons from 2016 to 2017 to a high of 709 million additional gallons from 2015 to 2016. These changes were likely influenced by multiple factors such as the cost of biodiesel feedstocks and petroleum diesel, the status of the biodiesel blenders tax credit, growth in marketing of biodiesel at high volume truck stops and centrally fueled fleet locations, demand for biodiesel and renewable diesel in other countries, biofuel policies in both the U.S. and foreign countries, and the volumes of renewable fuels (particularly advanced biofuels) required by the RFS. This historical information does not indicate that the maximum previously observed increase of 709 million gallons of advanced biodiesel and renewable diesel would be reasonable to expect in 2020, nor does it indicate that the low (or negative) growth rates observed in other years would recur. Rather, these data illustrate both the magnitude of the changes in advanced biodiesel and renewable diesel in previous years and the significant variability in these changes. 
The historic data indicates that the 
biodiesel tax policy in the U.S. can have a significant impact on the volume of biodiesel and renewable diesel used in the U.S. in any given year.
87While the 
biodiesel blenders tax credit has applied in each year from 2010 to 2017, it has only been prospectively in effect during the calendar year in 2011, 2013, and 2016, while other years it has been applied retroactively. Each of the years in which the biodiesel blenders tax credit was in effect during the calendar year (2013 and 2016) resulted in significant increases in the volume of advanced biodiesel and renewable diesel used in the U.S. over the previous 
year (656 million gallons and 742 million gallons respectively). However, following these large increases in 2013 and 2016, there was little to no growth in the use of advanced biodiesel and renewable diesel in the following years. More recent data from 2019 suggests that while the availability of the tax credit certainly incentivizes an increasing supply of biodiesel and renewable diesel, supply increases can also occur in the absence of the tax credit, likely as the result of the incentives provided by the RFS program and other economic factors. The availability of this tax credit also provides biodiesel and renewable diesel with a competitive advantage relative to other advanced biofuels that do not qualify for the tax credit.
88 
Another important factor highlighted 
by the historic data is the tariffs imposed by the U.S. on biodiesel imported from Argentina and Indonesia. In December 2017 the U.S. International Trade Commission adopted tariffs on biodiesel imported from Argentina and Indonesia.
89According to data from 
EIA,90no biodiesel was imported from 
Argentina or Indonesia since September 2017, after a preliminary decision to impose tariffs on biodiesel imported from these countries was announced in August 2017. As a result of these tariffs, total imports of biodiesel into the U.S. were significantly lower in 2018 than they had been in 2016 and 2017. The decrease in imported biodiesel did not, however, result in a decrease in the volume of advanced biodiesel and renewable diesel supplied to the U.S. in 2018. Instead, higher domestic production of advanced biodiesel and renewable diesel, in combination with lower exported volumes of domestically produced biodiesel, resulted in an overall increase in the volume of advanced biodiesel and renewable diesel supplied in 2018. On July 9, 
2019, the Department of Commerce published a preliminary determination to reduce the countervailing duty on biodiesel imported from Argentina.
91If 
finalized this could result in increasing volumes of biodiesel imports from Argentina in future years. The historical data suggests that the 
2.83 billion gallons of advanced 
biodiesel and renewable diesel projected to be used to meet an advanced biofuel volume of 5.09 billion ethanol-equivalent gallons is attainable. This would represent a projected increase of approximately 90 million gallons from 2019 to 2020. This increase is less than the average increase in the volume of advanced biodiesel and renewable diesel used in the U.S. from 2011 through 2019 (212 million gallons per year) and significantly less than the highest annual increase during this time (742 million gallons from 2015 to 2016). We note, however, that this assessment does not consider the sources of feedstock that would be used to meet this increase, or the potential impacts of supplying 2.83 billion gallons of advanced biodiesel and renewable diesel, which are discussed in greater detail in the following sections. 
c. Consideration of Production Capacity 
and Distribution Infrastructure 
After reviewing the historical volume 
of advanced biodiesel and renewable diesel used in the U.S., EPA next considers other factors that may impact the production, import, and use of advanced biodiesel and renewable diesel in 2020. The production capacity of registered advanced biodiesel and renewable diesel production facilities is highly unlikely to limit the production of these fuels, as the total production capacity for biodiesel and renewable 
diesel at registered facilities in the U.S. (4.1 billion gallons) exceeds the volume of these fuels that are projected to be needed to meet the advanced biofuel volume for 2020 after exercising the cellulosic waiver authority (2.83 billion gallons).
92Significant registered 
production also exists internationally. Similarly, the ability for the market to distribute and use advanced biodiesel and renewable diesel appears unlikely constrain the growth of these fuels to a volume lower than 2.83 billion gallons. The investments required to distribute and use this volume of biodiesel and renewable diesel are expected to be manageable by the marketplace given the RIN value incentive, as this volume is approximately 90 million gallons greater than the volume of biodiesel and renewable diesel produced, imported, and used in the U.S. in 2019. The magnitude of the increase projected

93See ‘‘Projections of FOG biodiesel and 
renewable diesel 2015–2018,’’ memorandum from 
David Korotney to EPA Docket, EPA–HQ–OAR– 2019–0136. 94The October 2019 WASDE projects production 
of vegetable oils in 2019/2020 in the U.S. and the World to be 12.58 and 207.50 million metric tons respectively. To convert projected vegetable oil production to potential biodiesel and renewable diesel production we have used a conversion of 7.7 pounds of feedstock per gallon of biodiesel or renewable diesel (World Agricultural Supply and Demand Estimates. United States Department of Agriculture, Office of the Chief Economist. October 10, 2019. ISSN 1554–9089). In addition, global production of biodiesel is projected to be 44.2 billion liters (11.7 billion gallons) in 2020 according to the July 2019 OECD–FAO Agricultural Outlook. Based on the projected production of biodiesel by country we estimate that over 80% of this biodiesel (all biodiesel except that produced in Columbia, Indonesia, Malaysia, and Thailand) could qualify as advanced biofuel if the feedstocks meet the definition of renewable biomass. 
95These reasons include the demand for 
vegetable oil in the food, feed, and industrial markets both domestically and globally; constraints related to the production, import, distribution, and use of significantly higher volumes of biodiesel and renewable diesel; and the fact that biodiesel and renewable diesel produced from much of the vegetable oil available globally would not qualify as an advanced biofuel under the RFS program. 
96As discussed in more detail in this section, this 
159 million gallons increase is projected to be comprised of 94 million gallons from increased vegetable oil production, 17 million gallons from distillers corn oil, and 48 million gallons from waste fats, oils, and greases. 97The volume of advanced biodiesel and 
renewable diesel projected to be used to meet the 
advanced biofuel volume (2.83 billion gallons) is approximately 1 billion gallons greater than the volume of these fuels we projected would be used to meet the advanced biofuel volume for 2022 in the 2010 RFS final rule analyses (1.82 billion gallons). For a further discussion of this issue see Section 4.2.2.4 of the RTC. 
98For instance, see the draft GHG assessment of 
palm oil biodiesel and renewable diesel at 77 FR 
4300 (January 27, 2012). We believe palm or petroleum-derived products would likely be used to replace advanced biodiesel and renewable diesel diverted to the U.S. as these products are currently the lowest cost substitutes. from 2019 to 2020 (90 million gallons) 
is much smaller than the increases observed in previous years. These factors further support our finding that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable. 
d. Consideration of the Availability of 
Advanced Feedstocks 
We next consider the availability of 
advanced feedstocks that can be used to produce advanced biodiesel and renewable diesel. This assessment has two parts. First, we assess whether there are sufficient advanced feedstocks to produce 2.83 billion gallons of advanced biodiesel and renewable diesel. We find that the quantity of feedstocks exceeds the amount needed to do so, further supporting our conclusion that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable. Second, we assess whether the growth in advanced feedstocks suffices to produce 2.83 billion gallons of advanced biodiesel and renewable diesel without diverting advanced feedstocks or biofuels from existing uses, i.e., the reasonably 
attainable volume. We find that the reasonably attainable volume falls slightly short at 2.77 billion gallons. 
We believe the most reliable source 
for projecting the expected increase in virgin vegetable oils in the U.S. is USDA’s World Agricultural Supply and Demand Estimates (WASDE). At the time of our assessment for this rule, the October 2019 version was the most current version of the WASDE report. The October 2019 WASDE projects that production of vegetable oil in the U.S. in the 2019/2020 market year will be sufficient to produce approximately 3.6 billion gallons of biodiesel and renewable diesel (including both advanced and conventional biofuels) if the entire volume of vegetable oil was used to produce these fuels. Additional advanced biodiesel and renewable diesel could also be produced from waste fats, oils, and greases as they have been in past years.
93Thus, the 
availability of domestic vegetable oils, in combination the potential to source additional feedstocks from waste fats, oils, and greases, supports our conclusion that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable. 
In addition, the global production of 
vegetable oil projected in the 2019/2020 marketing year in the October 2019 WASDE would be sufficient to produce approximately 59.3 billion gallons of biodiesel and renewable diesel (including both advanced and conventional biofuels).
94While it would 
not be reasonable to assume that all, or even a significant portion, of global vegetable oil production globally or domestically could be available to produce biodiesel or renewable diesel supplied to the U.S. for a number of reasons,
95the large global supply of 
vegetable oil further indicates that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable in 2020. 
We now turn to the reasonably 
attainable volume of advanced biodiesel and renewable diesel, which we find to be 2.77 billion gallons. This volume represents the amount of advanced biodiesel and renewable diesel that can be supplied without relying on the diversion of advanced biofuels and feedstocks from existing uses and the associated harms of such diversions. We calculate this volume by summing the reasonable attainable volume from last year’s final rule (2.61 billion gallons) with the volume that can be produced from the projected increase in advanced feedstocks from 2019 to 2020 (159 million gallons).
96 
We acknowledge that an increase in 
the required use of advanced biodiesel and renewable diesel could be realized through the production or collection of additional advanced feedstocks, a diversion of advanced feedstocks from other uses, or a diversion of advanced 
biodiesel and renewable diesel from existing markets in other countries. As already explained, the volume of advanced biodiesel and renewable diesel and their corresponding feedstocks projected to be produced globally exceeds the volume projected to be required in 2020 (2.83 billion gallons of advanced biodiesel and renewable diesel and the corresponding volume of advanced feedstocks) by a significant margin. However, we expect that increases in advanced biofuel and renewable fuel volumes beyond those that can be produced from the projected growth in advanced feedstock production and/or consumption (e.g., by 
diverting advanced feedstocks or advanced biodiesel and renewable diesel from existing markets and uses) would be increasingly likely to incur adverse unintended impacts.
97 
This is because of several factors, 
notably the potential disruption of the current biogenic fats, oils, and greases market, the associated cost impacts to other industries resulting from feedstock diversion, and the potential adverse effect on lifecycle GHG emissions and energy security associated with feedstocks for biofuel production that would have been used for other purposes and which must then be backfilled with other feedstocks.
98 
Similarly, increasing the supply of biodiesel and renewable diesel to the U.S. by diverting fuel that would otherwise have been used in other countries results in higher lifecycle GHG emissions than if the supply of these fuels was increased by an increased collection of waste fats and oils or increased production of feedstocks that are byproducts of other industries, especially if this diversion results in increased consumption of petroleum fuels in the countries that would have otherwise consumed the biodiesel or renewable diesel. By assessing the expected growth in the production of advanced feedstocks, we are attempting to minimize the incentives for the RFS program to increase the supply of advanced

grown primarily for animal feed or ethanol 
production, while soy and canola are primarily grown as livestock feed. 
100According to EIA data 7,542 million pounds 
of soy bean oil and 2,085 million pounds of corn oil were used to produce biodiesel in the U.S. in 2018. Other significant sources of feedstock were yellow grease (1,668 million pounds), canola oil (total volume withheld, but monthly data suggests greater than 700 million pounds), and white grease (618 million pounds).’’Monthly Biodiesel Production Report with Data for February 2019,’’ U.S. Energy Information Administration.

101This position is supported by several 
commenters, including the American Soybean Association (EPA–HQ–OAR–2019–0136–0177) and the Nebraska Soybean Association (EPA–HQ–OAR– 2019–0136–0117). 
102U.S. vegetable oil production is projected to be 
12.25 million metric tons in the 2018/2019 agricultural marketing year and 12.58 million 
metric tons in the 2019/2020 agricultural marketing year. 
103To calculate this volume, we have used a 
conversion of 7.7 pounds of feedstock per gallon of biodiesel or renewable diesel. This is based on the expected conversion of soybean oil (http://extension.missouri.edu/p/G1990), which is the largest source of feedstock used to produce advanced biodiesel and renewable diesel. Conversion rates for other types of vegetable oils used to produce biodiesel and renewable diesel are similar to those for soybean oil. 
104Distillers corn oil is non-food grade corn oil 
produced by ethanol production facilities. 
105For the purposes of this rule, EPA relied on 
WAEES modeling results submitted as comments by the National Biodiesel Board on the 2020 proposed rule (Kruse, J., ‘‘Implications of an Alternative 2021 Biomass Based Diesel Volume Obligation for Global Agriculture and Biofuels,’’ August 26, 2019, World Agricultural Economic and Environmental Services (WAEES)).

increase in 2019/2020 and a 16 million gallon increase in 2020/2021. See Kruse, J., ‘‘Implications of an Alternative Biomass Based Diesel Volume Obligation for Global Agriculture and Biofuels,’’ August 26, 2019, World Agricultural Economic and Environmental Services.

3880). biodiesel and renewable diesel through 
feedstock switching or diverting biodiesel and renewable diesel from foreign markets to the U.S. 
Advanced biodiesel and renewable 
diesel feedstocks include both waste oils, fats, and greases; and oils from planted crops. The projected growth in these feedstocks is expected to be modest relative to the volume of these feedstocks that is currently being used to produce biodiesel and renewable diesel. Most of the waste oils, fats, and greases that can be recovered economically are already being recovered and used in biodiesel and renewable diesel production or for other purposes. The availability of animal fats will likely increase with beef, pork, and poultry production. Most of the vegetable oil used to produce advanced biodiesel and renewable diesel that is sourced from planted crops comes from crops primarily grown for purposes other than providing feedstocks for biodiesel and renewable diesel, such as for livestock feed, with the oil that is used as feedstock for renewable fuel production a co-product.
99This is true 
for soybeans and corn, which are the two largest sources of feedstock from planted crops used for biodiesel production in the U.S.
100We do not 
believe that the increased demand for soybean oil or corn oil caused by a higher 2020 advanced biofuel standard would result in an increase in soybean or corn prices large enough to induce significant changes in agricultural activity.
101However, production of 
these feedstocks is likely to increase over time as crop yields, oil extraction rates, and demand for the primary products increase. 
Based on the October 2019 WASDE 
report the projected increase in vegetable oil production in the U.S. from the 2018/2019 marketing year to the 2019/2020 marketing year is 0.33 million metric tons per year.
102This additional quantity of vegetable oils could be used to produce approximately 94 million additional gallons of advanced biodiesel or renewable diesel in 2020 relative to 2019.
103 
In the 2019 final rule we also noted 
that the WASDE projected a decrease in trade of both oilseeds and vegetable oils. The projected decrease in oilseed trade was likely due to tariffs enacted by China on soybean exports from the U.S. While the projected trade in oilseeds is expected to increase slightly from 2018/ 2019 to 2019/2020, trade in vegetable oils is projected to decrease by 0.12 million metric tons from 2018/2019 to 2019/2020. If converted to biodiesel, this volume of vegetable oils could be used to produce approximately 34 million additional gallons of advanced biodiesel or renewable diesel in 2020 relative to 2019. As in the 2019 final rule, we did not include in our projection of the reasonably attainable volumes the potential biodiesel or renewable diesel that could theoretically be produced from the oilseeds and vegetable oil projected to remain in the U.S. due to changes in trade of these products. This is because any biodiesel and renewable diesel produced from soybeans previously exported are necessarily diverted from other uses (even if the reason for this diversion is the tariffs, rather than the RFS program), and biodiesel produced from these diverted feedstocks is therefore more likely to have the adverse unintended effects as previously discussed. 
In addition to virgin vegetable oils, we 
also expect increasing volumes of distillers corn oil
104to be available for 
use in 2020. The WASDE report does not project distillers corn oil production, so EPA must use an alternative source to project the growth 
in the production of this feedstock. For this final rule we use results from the World Agricultural Economic and Environmental Services (WAEES) model to project the growth in the production of distillers corn oil.
105In assessing the likely increase in the availability of 
distillers corn oil from 2019 to 2020, the authors of the WAEES model considered the effects of an increasing adoption rate of distillers corn oil extraction technologies at domestic ethanol production facilities, as well as increased corn oil extraction rates 
enabled by advances in this technology. The WAEES model projects that production of distillers corn oil will increase by approximately 130 million pounds from the 2018/2019 to the 2019/ 2020 agricultural marketing year. This quantity of feedstock could be used to produce approximately 17 million gallons of advanced biodiesel or renewable diesel. We believe it is reasonable to use these estimates from the WAEES model for these purposes based on the projected increase in the use of corn oil extraction and corn oil yield increases. 
While much of the increase in 
advanced biodiesel and renewable diesel feedstocks produced in the U.S. from 2019 to 2020 is expected to come from virgin vegetable oils and distillers corn oil, increases in the supply of other sources of advanced biodiesel and renewable diesel feedstocks, such as biogenic waste fats, oils, and greases (FOG), could also occur. In scenarios with increases to the advanced biofuel and biomass-based diesel volume requirements in 2020 and 2021 the WAEES model projects minimal increases in the volume of biodiesel produced from total other fats and oils in the 2018/2019 and 2019/2020 marketing years.
106Conversely, an 
assessment conducted by LMC International in 2017 and submitted in comments on our 2018 proposed rule projected that the waste oil supply in the U.S. could increase by approximately 2.4 million metric tons from 2016 to 2022.
107This estimate 
represents a growth rate of approximately 0.4 billion tons per year, or enough feedstock to produce approximately 115 million gallons of biodiesel and renewable diesel per year. This estimate, however, only accounts for potential sources of feedstock and

10983 FR 63704 (December 11, 2018). 
110We calculated the reasonably attainable 
volume for 2020 by adding the projected increase 
in advanced feedstocks (159 million gallons) to the reasonably attainable volume of these fuels we projected for 2019 (2.61 billion gallons). Another possible approach would be to add the 159-million- gallon increment in the reasonably attainable volume to the volume we now project to be used in 2019, 2.74 billion gallons (rather than the reasonably attainable volume we projected for 2019). This would result in a reasonably attainable volume of 2.90 billion gallons. While this approach uses more recent data on the availability of advanced biodiesel and renewable diesel in 2019, it does not account for whether or not the additional use of these fuels in 2019, beyond the reasonably attainable volume calculated in the 2019 final rule, resulted in diversions of advanced biofuels or feedstocks. In any event, even were we to adopt this approach, it would make no difference to our final decision on the volumes as (1) the difference in the calculated reasonably attainable volume is slight, (2) the high costs of advanced biodiesel and renewable diesel would justify exercising the maximum cellulosic waiver in any event, and (3) the volume we are finalizing is attainable under either approach. 
111Projection is based on EIA data on exports of 
biomass-based diesel (biodiesel) through July 2019. For more detail on this projection see ‘‘Projecting Advanced Biofuel Production and Imports for 2019 (November 2019),’’ memorandum from Dallas Burkholder to EPA docket EPA–HQ–OAR–2019– 0136. not for the economic viability of 
recovering waste oils. 
To project the increase in the use of 
biogenic FOG we used historical data to determine the increase in the use of these feedstocks to produce biodiesel and renewable diesel. From 2015–2018, advanced biodiesel and renewable diesel produced from biogenic FOG increased by an average of 48 million gallons per year.
108This annual increase 
is higher than the increase in the use of these feedstocks projected by the WAEES model, but lower than the potential increase projected by LMC. We have included an additional 48 million gallons of advanced biodiesel and renewable diesel from FOG in our assessment of the reasonably attainable volume for 2020, consistent with the observed annual increase in advanced biodiesel and renewable diesel produced from these feedstocks in recent years. 
In total, we project that increases in 
feedstocks produced in the U.S. are sufficient to produce approximately 159 million more gallons of advanced biodiesel and renewable diesel in 2020 relative to 2019. This number includes 94 million gallons from increased vegetable oil production, 17 million gallons from increased corn oil production, and 48 million gallons from increased waste oil collection. This increase does not include the projected 34 million gallons of biodiesel that could be produced from the projected reduction in vegetable oil trade since decreases in exported volumes of vegetable oils represent feedstocks diverted from use in other countries. Our projection also does not consider factors that could potentially affect the availability of advanced biofuel feedstocks that could be used to produce biodiesel or renewable diesel, such as changes in the volume of vegetable oils used in food markets or other non-biofuel industries. In our 2019 final rule, we determined that 2.61 billion gallons of advanced biodiesel and renewable diesel were reasonably attainable in 2019,
109therefore our 
projection of the reasonably attainable volume of advanced biodiesel and renewable diesel in 2020 is 2.77 billion 
gallons.
110 e. Biodiesel and Renewable Diesel 
Imports and Exports 
EPA next considered potential 
changes in the imports of advanced biodiesel and renewable diesel produced in other countries. In previous years, significant volumes of foreign produced advanced biodiesel and renewable diesel have been supplied to markets in the U.S. (see Table IV.B.2–1). These significant imports were likely the result of a strong U.S. demand for advanced biodiesel and renewable diesel, supported by the RFS standards, the low carbon fuel standard (LCFS) in California, the biodiesel blenders tax credit, and the opportunity for imported biodiesel and renewable diesel to realize these incentives. We have not included the potential for increased (or decreased) volumes of imported 
advanced biodiesel and renewable diesel in our projection of the reasonably attainable volume for 2020. As discussed previously, any increases in the import of advanced biodiesel and renewable diesel is necessarily diverted from other markets. There is also a far higher degree of uncertainty related to the availability and production of advanced biodiesel and renewable diesel in foreign countries, as this supply can be affected by a number of unpredictable factors such as the imposition of tariffs and increased incentives for the use of these fuels in other countries (such as tax incentives or blend mandates). EPA also lacks the data necessary to determine the quantity of these fuels that would otherwise be produced and used in other countries, and thus the degree to which the RFS standards are simply diverting this fuel from use in other countries as opposed to incentivizing additional production. 
While we do not consider changes in 
imports or exports of advanced biodiesel and renewable diesel in our projection of the reasonably attainable volume, changes to the volume of these fuels that is imported and exported could potentially impact the attainable 
volume. Imports of advanced biodiesel and renewable diesel are projected to increase by 150 million gallons from 2018 to 2019 (from approximately 350 million gallons in 2018 to approximately 500 million gallons in 2019, see Table IV.B.3–2). At the same time, data through July 2019 suggests that the U.S. will export approximately 122 million gallons of domestically produced biodiesel in 2019.
111 
Increased imports and/or decreased exports of these fuels in 2020 could contribute to the market supplying 2.83 billion gallons of advanced biodiesel and renewable diesel. The higher volumes of imported advanced biodiesel and renewable diesel in previous years (shown in Table IV.B.3–2) suggest that these changes are possible, especially if the tariffs on biodiesel imported from Argentina are reduced. Thus the potential for increased imports and decreased exports further supports our determination that 2.83 billion gallons of advanced biodiesel and renewable diesel is attainable. 
While changes to the volumes of 
imports/exports of advanced biodiesel 
and renewable could supply the approximately 60 million gallon difference between the reasonably attainable volume of these fuels (2.77 billion gallons) and the volume needed to meet an advanced biofuel volume of 5.09 billion ethanol-equivalent gallons (2.83 billion gallons), these changes are not without impacts. Diverting this fuel to markets in the U.S. may be complicated as doing so would likely require higher prices for these fuels in the U.S. to divert the fuels from foreign markets that are presumably more profitable currently. It may also be more difficult and costly to distribute this additional volume of biodiesel and renewable diesel to domestic markets than the current foreign markets. Finally, reducing advanced biodiesel and renewable diesel exports may indirectly result in the decreased availability of imported volumes of these fuels, as other countries seek to replace volumes previously imported from the U.S.

114‘‘Updated market impacts of biofuels in 2020,’’ 
memorandum from David Korotney to docket EPA– HQ–OAR–2019–0136. In prior actions, similar analyses to those described in this memorandum indicated that the market was capable of both producing and consuming the required volume of renewable fuels, and that as a result there was no basis for finding an inadequate domestic supply of total renewable fuel. See 82 FR 34229 & n.82 (July 21, 2017). Given the D.C. Circuit’s decision in ACE, however, assessment of demand-side constraints is no longer relevant for determining inadequate domestic supply. Even so, we believe consideration of the ways that the market could make this volume available may still be generally relevant to whether and how EPA exercises its waiver authorities, such as our consideration of whether the volumes will cause severe economic harm. 
115We note that the previously cited 
memorandum discusses the potential for total 
ethanol consumption in 2020, but does not make specific projections for E0, E15 and E85. Volumes of these ethanol blends are highly dependent upon consumer demand and retail distribution infrastructure. In prior annual rules, we assessed volumes of these blends in determining whether and to what extent to exercise the inadequate domestic supply waiver prong of the general waiver authority. The D.C. Circuit’s decision ACE precludes assessment of demand-side constraints in determining inadequate domestic supply. While we could still assess such blend volumes in deciding whether and to what extent to exercise our other discretionary waiver authorities, and in evaluating the market’s ability to meet the total renewable fuel requirement, doing so is not necessary. In terms of the market’s ability to satisfy the total renewable fuel requirement, the more relevant consideration is whether the pool-wide ethanol volume, together with volumes of other biofuels, suffices. We note that EPA does not establish separate standards for E0, E15, or E85. Moreover, there has historically been a lack of reliable data on volumes of these blends, making reliance on the pool-wide ethanol volume a more technically robust approach. diesel projected to be needed to achieve 
an advanced biofuel volume of 5.09 billion ethanol-equivalent gallons are attainable. We have reached this conclusion based on our analysis of the above factors, including historical supply of biodiesel and renewable diesel, the impacts of tax policy and tariffs, production capacity and distribution infrastructure, availability of advanced feedstocks, and imports and exports. By contrast, we find that only 2.77 billion gallons of advanced biodiesel and renewable diesel are reasonably attainable. This estimate is based on our analysis of growth in qualifying feedstocks, and represents the volume that can be supplied with minimal diversions of advanced biofuels and feedstocks from existing uses, and the associated harms of such diversions. These assessments support EPA’s decision to establish the advanced biofuel volume for 2020 at 5.09 billion gallons, a volume which neither requires the use of EPA’s general waiver authority nor the use of additional volumes of advanced biofuel in place of cellulosic biofuel. 
C. Volume Requirement for Advanced 
Biofuel 
In exercising the cellulosic waiver 
authority for 2017 and earlier, we determined it was appropriate to require a partial backfilling of missing cellulosic volumes with volumes of non-cellulosic advanced biofuel we determined to be reasonably attainable, notwithstanding the increase in costs associated with those decisions.
112For the 2018 and 
2019 standards, in contrast, we placed a greater emphasis on costs in the context of balancing the various considerations, ultimately concluding that the applicable volume requirement should be based on the maximum reduction permitted under the cellulosic waiver authority, effectively preventing any backfilling of missing cellulosic biofuel with advanced biofuel. In setting the 2019 standards, we also found that greater volumes of advanced biofuel would be attainable but did not believe that requiring higher volumes would be appropriate as such volumes were not reasonably attainable and would lead to diversion of advanced feedstocks or biofuels and the associated harms. 
For 2020, we are following the same 
approach as in 2018 and 2019 and exercising the cellulosic waiver authority to reduce the advanced biofuel requirement by the maximum extent permitted. This results in an advanced biofuel volume of 5.09 billion gallons. This also preserves the implied statutory volume target for non- cellulosic advanced biofuel at 4.5 billion gallons, identical to that for 2019. As in the 2019 standards, we are taking this approach for two reasons, each of which is an independent and sufficient justification. First, as in 2019, the reasonably attainable volume of advanced biofuel for 2020 falls short of the volume resulting from the maximum exercise of the cellulosic authority. It is thus appropriate to exercise the cellulosic waiver authority to the maximum extent to minimize the harms associated with advanced biofuel and feedstock diversions. 
Second, even if greater volumes of 
advanced biofuel are reasonably attainable, the high cost of these fuels independently justifies reducing the advanced biofuel volume for 2020 by the maximum amount permitted under the cellulosic waiver authority. In the 2019 final rule we presented illustrative cost projections for sugarcane ethanol and soybean biodiesel in 2019, the two advanced biofuels that would be most likely to provide the marginal increase in volumes of advanced biofuel in 2019 in comparison to 2018. Sugarcane ethanol results in a cost increase compared to gasoline that ranges from $0.39–$1.04 per ethanol-equivalent gallon. Soybean biodiesel results in a cost increase compared to diesel fuel that ranges from $0.74–$1.23 per ethanol-equivalent gallon. Thus, the cost of these renewable fuels is high as compared to the petroleum fuels they displace. 
In conclusion, we believe that a 2020 
advanced biofuel volume requirement of 5.09 billion ethanol-equivalent gallons is appropriate following our assessment 
of volumes that are attainable and in consideration of carryover RINs, potential feedstock/fuel diversions, and costs. Comments requesting higher or lower volumes are addressed in the separate Response to Comments document. 
D. Volume Requirement for Total 
Renewable Fuel 
As discussed in Section II.A.1, we 
believe that the cellulosic waiver provision is best interpreted as requiring that the advanced biofuel and total renewable fuel volumes be reduced by equal amounts. For the reasons we have previously articulated, we believe this interpretation is consistent with the statutory language and best effectuates the objectives of the statute, including the environmental objectives that generally favor the use of advanced biofuels over non-advanced biofuels and 
the legislative intent reflected in the statutory volume tables.
113If we were to 
reduce the total renewable fuel volume requirement by a lesser amount than the advanced biofuel volume requirement, we would effectively increase the opportunity for conventional biofuels to participate in the RFS program beyond the implied statutory volume of 15 billion gallons. Applying an equal reduction of 9.91 billion gallons to both the statutory target for advanced biofuel and the statutory target for total renewable fuel results in a total renewable fuel volume of 20.09 billion gallons as shown in Table IV.A–1. This volume of total renewable fuel results in an implied volume of 15 billion gallons of conventional renewable fuel, which is the same as in the 2019 final rule. We have investigated the different ways that the market could respond to a total renewable fuel volume requirement of 20.09 billion gallons in a memorandum to the docket.

We note that the statute provides 
other authorities for EPA to reduce the required volumes beyond that permitted

section, EPA has not attempted to adjust the price of the petroleum fuels to account for the impact of the RFS program, since the changes in the renewable fuel volume are relatively modest in comparison to the quantity of fuel associated with the petroleum market. Rather, we have used the wholesale price projections for gasoline and diesel as reported in EIA’s October 2019 STEO. by the cellulosic waiver. As explained 
in Section II of this rule and in Section 2 of the Response to Comments document, we do not believe it is appropriate to further reduce volumes under the general waiver authority. 
We acknowledge that there is some 
uncertainty regarding whether the market will actually make available 5.09 billion ethanol-equivalent gallons of advanced biofuel or 20.09 billion ethanol-equivalent gallons of total renewable fuel in 2020. In the event that the market is not able to meet these volume requirements with biofuels produced and used in 2020, the carryover RIN bank represents a source of RINs that could help obligated parties meet them if the market fails to supply sufficient advanced biofuels. As discussed in greater detail in Section II.B.1, carryover RINs provide obligated parties compliance flexibility in the face of substantial uncertainties in the transportation fuel marketplace and provide a liquid and well-functioning RIN market upon which success of the entire program depends. We currently estimate that there are approximately 680 million advanced biofuel carryover RINs and 2.80 billion non-advanced (D6) carryover RINs available. 
V. Impacts of 2020 Volumes on Costs 
In this section, EPA presents its 
assessment of the illustrative costs of 
this final RFS annual rulemaking. It is important to note that these illustrative costs do not attempt to capture the full impacts of this final rule. We frame the analyses we have performed for this rule as ‘‘illustrative’’ so as not to give the impression of comprehensive estimates. These estimates are provided for the purpose of showing how the cost to produce a gallon of a ‘‘representative’’ renewable fuel compares to the cost of fossil fuels (e.g., petroleum-derived 
fuels). There are a significant number of 
caveats that must be considered when interpreting these illustrative cost estimates. For example, there are many different feedstocks that could be used to produce biofuels, and there is a significant amount of heterogeneity in the costs associated with these different feedstocks and fuels. Some renewable fuels may be cost competitive with the fossil fuels they replace; however, we do not have cost data on every type of feedstock and every type of fuel. Therefore, we do not attempt to capture this range of potential costs in our illustrative estimates. 
The renewable fuel volumes for 
which we provide cost estimates are described in Section III. In this section, we estimate illustrative costs for two different cases. In the first case, we provide illustrative cost estimates by comparing the final 2020 RFS renewable fuel volumes to 2020 RFS statutory renewable fuel volumes. In the second case, we examine the final 2020 RFS renewable fuel volumes to the final 2019 RFS renewable fuel volumes to estimate changes in the annual costs of the final 2020 RFS annual rule in comparison to the final 2019 RFS annual rule.
116 
A. Illustrative Costs Analysis of 2020 Final Volumes Compared to the 2020 Statutory Volumes Baseline 
In this section, EPA provides 
illustrative cost estimates that compare the final 2020 RFS cellulosic renewable volume requirement to the 2020 RFS cellulosic statutory renewable fuel volume that would be required absent the exercise of our cellulosic waiver authority under CAA section 211(o)(7)(D)(i). As described in Section III, we are finalizing a cellulosic volume of 0.59 billion gallons for 2020, using our cellulosic waiver authority to waive the statutory cellulosic volume of 10.5 billion gallons by 9.91 billion gallons. Estimating the cost savings from renewable fuel volumes that are not projected to be produced is inherently challenging. EPA has taken the relatively straightforward methodology of multiplying the waived cellulosic volume by the wholesale per-gallon costs of cellulosic biofuel production relative to the fossil fuels they displace. 
While there may be growth in other 
cellulosic renewable fuel sources, we believe it is appropriate to use cellulosic ethanol produced from corn kernel fiber at an existing corn starch ethanol production facility as representative of cellulosic renewable fuel. As explained in Section III, we believe that production of the major alternative cellulosic biofuel—compressed natural gas/liquefied natural gas (CNG/LNG)- derived from biogas—is constrained in 2020 due to a limitation in the number of vehicles capable of using this form of fuel.
117 
EPA uses a ‘‘bottom-up’’ engineering 
cost analysis to quantify the costs of producing a gallon of cellulosic ethanol derived from corn kernel fiber. There are multiple processes that could yield cellulosic ethanol from corn kernel fiber. EPA assumes a cellulosic ethanol production process that generates 
biofuel using distiller’s grains, a co- product of generating corn starch ethanol that is commonly dried and sold into the feed market as distillers dried grains with solubles (DDGS), as the renewable biomass feedstock. We assume an enzymatic hydrolysis process with cellulosic enzymes to break down the cellulosic components of the distiller’s grains. This process for generating cellulosic ethanol is similar to approaches currently used by industry to generate cellulosic ethanol at a commercial scale, and we believe these cost estimates are likely representative of the range of different technology options being developed to produce ethanol from corn kernel fiber. We then compare the per-gallon costs of the cellulosic ethanol to the fossil fuel that would be replaced at the wholesale stage, since that is when the two are blended together. 
These cost estimates do not consider 
taxes, retail margins, or other costs or transfers that occur at or after the point of blending. Transfers are payments within society and are not additional costs (e.g., RIN payments are one 
example of a transfer payment). We do not attempt to estimate potential cost savings related to avoided infrastructure costs (e.g., the cost savings of not having 
to provide pumps and storage tanks associated with higher-level ethanol blends). When estimating per-gallon costs, we consider the costs of gasoline on an energy-equivalent basis as compared to ethanol, since more ethanol gallons must be consumed to travel the same distance as on gasoline due to the ethanol’s lower energy content. 
Table V.A–1 below presents the 
cellulosic fuel cost savings associated with this final rule that are estimated using this approach.
118The per-gallon 
cost differences for cellulosic ethanol range from $0.46–$3.30 per ethanol- equivalent gallon ($/EEG).
119Given that 
commercial cellulosic ethanol production is still at an early stage in its deployment, these cost estimates have a significant range. Multiplying the per-

120For this table and all subsequent tables in this 
section, approximate costs in per-gallon cost 
difference estimates are rounded to the cents place. 
121Since the proposed rule, we have updated 
these per-gallon and total annual cost differences 
based on EIA’s updated projections for petroleum gasoline costs in 2020 from the October Short-Term Energy Outlook. 
122For this table and all subsequent tables in this 
section, approximate resulting costs (other than in per-gallon cost difference estimates) are rounded to two significant figures. 123The current version of this model and user’s 
manual are downloadable from the LMOP website.

124For the proposed 2020 annual RFS rule, we 
estimated that there would be an increase of cellulosic biofuel derived from CNG/LNG from landfill biogas of 126 million gallons (ethanol- 
equivalent) compared to the 2019 final annual RFS volumes. The total costs of the proposed 2020 cellulosic volume compared to 2019 RFS cellulosic volume range from $(3.2)–$10 million. In this final rule, both the projected volume increase of CNG/ 
LNG derived from biogas and the cost of natural gas to which this fuel is compared have been updated.

B. Illustrative Cost Analysis of the 2020 
Final Volumes Compared to the 2019 Final Volumes 
In this section, we provide illustrative 
cost estimates for the final 2020 RFS 
volumes compared to the final 2019 RFS volumes. In comparison to the final 2019 RFS volumes, the final 2020 RFS volumes result in an overall increase of 172 million ethanol-equivalent gallons of cellulosic biofuel derived from CNG/ LNG from landfill biogas. To estimate the cost of production of CNG/LNG derived from landfill gas (LFG), EPA uses Version 3.2 of the Landfill Gas Energy Cost Model, or LFGcost-Web.
123 
LFGcost-Web is a software tool 
developed by EPA’s Landfill Methane Outreach Program (LMOP) to conduct initial economic feasibility analysis of developing LFG energy recovery projects in the United States. The default inputs and cost estimates by LFGcost-Web are based on typical project designs and for typical landfill situations. The Model attempts to include all equipment, site work, permits, operating activities, and maintenance that would normally be required for constructing and operating a typical project. Table V.B–1 presents estimates of per 
energy-equivalent gallon costs for 
producing CNG/LNG derived from landfill biogas relative to natural gas at the wholesale level. These per-gallon costs are then multiplied by the increase in the final 2020 RFS cellulosic biofuel volume relative to the 2019 final RFS cellulosic biofuel volume to obtain an estimate of costs of using increased qualities of CNG/LNG from landfill biogas. An estimate of overall costs associated with the increase in the cellulosic biofuel volume is calculated as the range of $(1.1)–$17 million.

The annual volume-setting process 
encourages consideration of the RFS 
program on a piecemeal (i.e., year-to- 
year) basis, which may not reflect the full, long-term costs and benefits of the program. For the purposes of this final rule, other than the estimates of costs of producing a ‘‘representative’’ renewable fuel compared to cost of fossil fuel, EPA did not quantitatively assess other direct and indirect costs or benefits of changes in renewable fuel volumes. These direct and indirect costs and benefits may include infrastructure costs, investment, climate change impacts, air quality impacts, and energy security benefits, 
which all to some degree may be 
affected by the annual volumes. For example, we do not have a quantified estimate of the lifecycle GHG or energy security benefits for a single year (e.g., 2020). Also, there are impacts that are difficult to quantify, such as rural economic development and employment changes from more diversified fuel sources, that are not quantified in this rulemaking. While some of these impacts were analyzed in the 2010 final rulemaking that established the current RFS program, we have not analyzed these impacts for the 
2020 volume requirements.

VI. Biomass-Based Diesel Volume for 2021 
In this section we discuss the BBD 
applicable volume for 2021. We are 
setting this volume in advance of those for other renewable fuel categories in light of the statutory requirement in CAA section 211(o)(2)(B)(ii) to establish the applicable volume of BBD for years after 2012 no later than 14 months before the applicable volume will apply. We are not at this time setting the BBD

F.3d 628, 666 (D.C. Cir 2019). percentage standards that would apply 
to obligated parties in 2021 but intend to do so in late 2020, after receiving EIA’s estimate of gasoline and diesel consumption for 2021. At that time, we will also set the percentage standards for the other renewable fuel types for 2021. Although the BBD applicable volume sets a floor for required BBD use, because the BBD volume requirement is nested within both the advanced biofuel and the total renewable fuel volume requirements, any BBD produced can be used to satisfy both of these other applicable volume requirements, even beyond the mandated BBD volume. 
A. Statutory Requirements 
The statute establishes applicable 
volume targets for years through 2022 
for cellulosic biofuel, advanced biofuel, and total renewable fuel. For BBD, applicable volume targets are specified in the statute only through 2012. For years after those for which volumes are specified in the statute, EPA is required under CAA section 211(o)(2)(B)(ii) to determine the applicable volume of BBD, in coordination with the Secretary of Energy and the Secretary of Agriculture, based on a review of the implementation of the program during calendar years for which the statute specifies the volumes and an analysis of the following factors: 
1. The impact of the production and 
use of renewable fuels on the environment, including on air quality, climate change, conversion of wetlands, 
ecosystems, wildlife habitat, water quality, and water supply; 
2. The impact of renewable fuels on 
the energy security of the United States; 
3. The expected annual rate of future 
commercial production of renewable fuels, including advanced biofuels in each category (cellulosic biofuel and BBD); 
4. The impact of renewable fuels on 
the infrastructure of the United States, including deliverability of materials, goods, and products other than renewable fuel, and the sufficiency of infrastructure to deliver and use renewable fuel; 5. The impact of the use of renewable 
fuels on the cost to consumers of 
transportation fuel and on the cost to transport goods; and 
6. The impact 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. 
The statute also specifies that the 
volume requirement for BBD cannot be less than the applicable volume specified in the statute for calendar year 2012, which is 1.0 billion gallons.
126 
The statute does not, however, establish any other numeric criteria, and provides EPA discretion over how to weigh the importance of the often competing factors and the overarching goals of the statute when the EPA sets the applicable volumes of BBD in years after those for which the statute specifies such volumes. In the period 2013–2022, the 
statute specifies increasing applicable volumes of cellulosic biofuel, advanced biofuel, and total renewable fuel, but provides no numeric criteria, beyond the 1.0 billion gallon minimum, on the level at which BBD volumes should be set. 
In establishing the BBD and cellulosic 
standards as nested within the advanced biofuel standard, Congress clearly intended to support development of BBD and especially cellulosic biofuels, while also providing an incentive for the growth of other non-specified types of advanced biofuels. In general, the advanced biofuel standard provides an opportunity for other advanced biofuels (advanced biofuels that do not qualify as cellulosic biofuel or BBD) to compete with cellulosic biofuel and BBD to satisfy the advanced biofuel standard after the cellulosic biofuel and BBD standards have been met. 
In Alon Refining Krotz Spring, Inc. v. 
EPA, the D.C. Circuit affirmed EPA’s 
approach to setting the 2017 BBD volume as ‘‘consistent with the structure and purposes of the statute.’’
127In 
today’s rule, we have applied the same general methodology upheld in Alon 
with updated information. Similar to the rule reviewed in Alon, today’s rule 
finds that it is the advanced biofuel 
standard, when set in 2021, that will drive the use of BBD in 2021. Furthermore, in light of the benefits of incentivizing other advanced biofuels, we choose to preserve the existing gap for other advanced biofuels, and accordingly establish the BBD volume at the same level as for 2020: 2.43 billion gallons. 
B. Review of Implementation of the 
Program and the 2021 Applicable Volume of Biomass-Based Diesel 
One of the considerations in 
determining the BBD volume for 2021 is a review of the implementation of the program to date, as it affects BBD. This review is required by the CAA, and also provides insight into the capabilities of the industry to produce, import, export, distribute, and use BBD. It also helps us to understand what factors, beyond the BBD standard, may incentivize the availability of BBD. In reviewing the program, we assess numerous regulatory, economic, and technical factors, including the availability of BBD in past years relative to the BBD and advanced standards; the prices of BBD, advanced, and conventional RINs; the competition between BBD and other advanced biofuels in meeting the portion of the advanced standard not required to be met by BBD or cellulosic RINs; the maturation of the BBD industry over the course of the RFS program; and the effects of the BBD standard on the production and development of both BBD and other advanced biofuels. 
Table VI.B.1–1 shows, for 2011–2019, 
the number of BBD RINs generated, the number of RINs retired due to export, the number of RINs retired for reasons other than compliance with the annual BBD standards, and the consequent number of available BBD RINs; for 2011–2019, the BBD and advanced biofuel standards; and for 2020, the BBD and advanced biofuel standards.

Reasons information from EMTs. 
129The number of RINs available in 2014 and 
2015 was approximately equal to the number required for compliance in those years, as the standards for these years were finalized at the end of November 2015 and EPA’s intent at that time was to set the standards for 2014 and 2015 to reflect actual BBD use. See 80 FR 77490–92, 77495 (December 14, 2015). 
130The biodiesel tax credit was reauthorized in 
January 2013. It applied retroactively for 2012 and for the remainder of 2013. It was once again extended in December 2014 and applied retroactively to all of 2014 as well as to the remaining weeks of 2014. In December 2015 the biodiesel tax credit was authorized and applied retroactively for all of 2015 as well as through the end of 2016. In February 2018 the biodiesel tax credit was authorized and applied retroactively for all of 2017. The biodiesel tax credit is not currently in place for 2018, 2019, or 2020. 131This is because when an obligated party retires 
a BBD RIN (D4) to help satisfy their BBD obligation, the nested nature of the BBD standard means that this RIN also counts towards satisfying their advanced and total renewable fuel obligations. Advanced RINs (D5) count towards both the advanced and total renewable fuel obligations, while conventional RINs (D6) count towards only the total renewable fuel obligation. 
132We would still expect D4 RINs to be valued 
at a slight premium to D5 and D6 RINs in this case (and D5 RINs at a slight premium to D6 RINs) to reflect the greater flexibility of the D4 RINs to be used towards the BBD, advanced biofuel, and total renewable fuel standard. This pricing has been observed over the past several years. 133Although we did not issue a rule establishing 
the final 2013 standards until August of 2013, we believe that the market anticipated the final standards, based on EPA’s July 2011 proposal and the volume targets for advanced and total renewable fuel established in the statute. (76 FR 38844, 38843 July 1, 2011). Similarly, for 2014 and 2015, although we issued the final standards in late 2015, the proposed rule incentivized the market to use

bThe volumes for each year are those used as the basis for calculating the percentage standards in the final rule. They have not been retro-
actively adjusted for subsequent events, such as differences between projected and actual gasoline and diesel use and exempted small refinery 
volumes. 
cEach gallon of biodiesel qualifies for 1.5 RINs due to its higher energy content per gallon than ethanol. Renewable diesel qualifies for be-
tween 1.5 and 1.7 RINs per gallon, but generally has an equivalence value of 1.7. While some fuels that qualify as BBD generate more than 1.5 RINs per gallon, EPA multiplies the required volume of BBD by 1.5 in calculating the percent standard per 80.1405(c). In 2014 and 2015 how-ever, the number of RINs in the BBD Standard column is not exactly equal to 1.5 times the BBD volume standard as these standards were es-tablished based on actual RIN generation data for 2014 and a combination of actual data and a projection of RIN generation for the last three months of the year for 2015, rather than by multiplying the required volume of BBD by 1.5. Some of the volume used to meet the BBD standard in these years was renewable diesel, with an equivalence value higher than 1.5. 
d2019 ‘‘BBD RINs generated,’’ ‘‘Exported BBD,’’ and ‘‘BBD RINs retired, Non-compliance reason’’ are projected based on data through Sep-
tember 2019. 
In reviewing historical BBD RIN 
generation and use, we see that the 
number of RINs available for compliance purposes exceeded the volume required to meet the BBD standard in 2011–13 and 2016–19.
129 
Additional production and use of biodiesel was likely driven by a number of factors, including demand to satisfy the advanced biofuel and total renewable fuels standards, the biodiesel tax credit,
130and various other State 
and local incentives and mandates allowing for favorable blending economics. Moreover, additional production of BBD, beyond the volumes shown in the above table, was exported. The prices paid for advanced biofuel 
and BBD RINs beginning in early 2013 
through September 2019 (the last month for which data is available) also support the conclusion that the advanced biofuel, and in some periods the total renewable fuel standards, provide a sufficient incentive for additional biodiesel volume beyond what is required by the BBD standard. Because the BBD standard is nested within the advanced biofuel and total renewable fuel standards, and therefore can help to satisfy three RVOs, we would expect the price of BBD RINs to exceed that of advanced and conventional renewable RINs.
131If, however, BBD RINs are 
being used (or are expected to be used) by obligated parties to satisfy their advanced biofuel obligations, above and beyond the BBD standard, we would expect the prices of advanced biofuel and BBD RINs to converge.
132Further, if BBD RINs are being used (or are expected to be used) to satisfy obligated parties’ total renewable fuel obligation, above and beyond their BBD and advanced biofuel requirements, we would expect the price for all three RIN types to converge. 
When examining RIN price data from 
2011 through September 2019, shown in Figure VI.B.2–1, we see that beginning in early 2013 and through September 2019 the advanced RIN (D5) price and BBD (D4) RIN prices were approximately equal. Similarly, from early 2013 through late 2016 the conventional renewable fuel (D6) RIN and BBD RIN prices were approximately equal. This demonstrates that the advanced biofuel standard, and in some periods the total renewable fuel standard, are capable of incentivizing increased BBD volumes beyond the BBD standard. The advanced biofuel standard has incentivized additional volumes of BBD since 2013, while the total standard had incentivized additional volumes of BBD from 2013 through 2016.
133We do note, however,

BBD volumes exceeding the proposed BBD standard 
to help satisfy the proposed advanced and total standards. See 80 FR 33100 (2014–16 standards proposed June 10, 2015); 78 FR 71732 (2014 standards proposed Nov. 29, 2013). 134See, e.g., Comments from Advanced Biofuel 
Association, available in EPA docket EPA–HQ–
OAR–2018–0167–1277. 135All types of advanced biofuel, including BBD, 
must achieve lifecycle GHG reductions of at least 50 percent. See CAA section 211(o)(1)(B)(i), (D). that in 2011–2012 the BBD RIN price 
was significantly higher than both the advanced biofuel and conventional renewable fuel RIN prices. At this time, the E10 blendwall had not yet been reached, and it was likely more cost effective for most obligated parties to satisfy the portion of the advanced biofuel requirement that exceeded the 
BBD and cellulosic biofuel requirements with advanced ethanol. 
We also examined the opportunity for 
advanced biofuels other than BBD and 
cellulosic biofuels, as shown in Table VI.B.1–2. We believe it is important to preserve this opportunity for other advanced biofuels, and we are conscious of public comments claiming that BBD volume requirements that are a significant portion of the advanced volume requirements effectively disincentivize the future development of other promising advanced biofuel pathways.

of advanced biofuels, rather than a single type such as BBD, would increase energy security (e.g., by increasing the diversity of feedstock sources used to make biofuels, thereby reducing the impacts associated with a shortfall in a particular type of feedstock) and increase the likelihood of the development of lower cost advanced biofuels that meet the same GHG reduction threshold as BBD.

aThe opportunity for ‘‘other’’ advanced biofuel is calculated by subtracting the number of cellulosic biofuel and BBD RINs required each year 
from the number of advanced biofuel RINs required. This portion of the advanced standard can be satisfied by advanced (D5) RINs, BBD RINs 
in excess of those required by the BBD standard, or cellulosic RINs in excess of those required by the cellulosic standard. 
bThe available BBD (D4) RINs in excess of the BBD requirement is calculated by subtracting the required BBD volume (multiplied by 1.5 to 
account for the equivalence value of biodiesel) required each year from the number of BBD RINs available for compliance in that year. This num-ber does not include carryover RINs, nor do we account for factors that may impact the number of BBD RINs that must be retired for compli-ance, such as differences between the projected and actual volume of obligated gasoline and diesel. The required BBD volume has not been retroactively adjusted for subsequent events, such as differences between projected and actual gasoline and diesel use and exempted small re-finery volumes. 
cThe 2014 and 2015 volume requirements were established in November 2015 and were set equal to the number of RINs projected to b e 
available for each year. 
dAvailable advanced RINs and available D4 RINs in excess of the BBD requirement are projected based on data through September 20 19. 
In each year since 2016, there has 
been a significant gap for other 
advanced biofuels, but this gap has nonetheless been dominated by BBD. While the RFS volumes created the opportunity for up to 530 million, 969 million, 852 million, and 1,352 million gallons of ‘‘other’’ advanced for 2016, 2017, 2018, and 2019 respectively to be used to satisfy the advanced biofuel obligation, only 98 million, 144 million, 178 million, and 310 million gallons of ‘‘other’’ advanced biofuels were generated. This is significantly less than the volumes of ‘‘other’’ advanced available in 2012–2013. Despite creating space within the advanced biofuel standard for ‘‘other’’ advanced, in recent years, only a small fraction of that space has been filled with ‘‘other’’ advanced, and BBD continues to fill most of the gap between the BBD standard and the advanced standard. Thus, there does not appear to be a compelling reason to increase the ‘‘space’’ maintained for ‘‘other’’ advanced biofuel volumes. 
This conclusion is consistent with our 
approach in the 2019 final rule, when we established the 2019 advanced biofuel volume and the 2020 BBD volume. The overall volume of non- cellulosic advanced biofuel increased by 500 million gallons for 2019. For the 2020 BBD volume, we determined that it was appropriate to also increase the BBD volume by the same energy- equivalent amount (330 million physical gallons) as it would preserve the space already available for other advanced biofuels to compete in 2018 (850 million RINs). This space is many times the amount of other advanced biofuels used in each year starting from 2016. 
In this action, we are maintaining the 
implied non-cellulosic advanced biofuel standard for 2021 that is presented in the statute, and that is equivalent to the implied non-cellulosic advanced biofuel standard for 2020. For the 2021 BBD volume, we thus find that it is appropriate to maintain the BBD volume for 2021 at 2.43 billion gallons. Even in an optimistic scenario, we do not believe that the use of other advanced biofuels will approach 850 million gallons by 2021. We recognize, however, the dynamic nature of the fuels marketplace, and the impact that the BBD blender’s tax credit can have on the relative economics of BBD versus other advanced biofuels, so going forward we intend to assess the appropriate space for other advanced biofuels in subsequent rules setting BBD volumes. 
At the same time, the rationale for 
preserving the ‘‘space’’ for ‘‘other’’ advanced biofuels remains. We note that the BBD industry in the U.S. and abroad has matured since EPA first increased the required volume of BBD beyond the statutory minimum in 2013.
136To 
assess the maturity of the biodiesel industry, EPA compared information on BBD RIN generation by company in 2012 and 2018 (the most recent year for which complete RIN generation by company is available). In 2012, the annual average RIN generation per company producing BBD was about 11 million RINs (about 7.3 million gallons) with approximately 50 percent of companies producing less than 1 million gallons of BBD a year.
137Since 
that time, the BBD industry has matured in a number of critical areas, including growth in the size of companies, the 
consolidation of the industry, and more stable funding and access to capital. By 2018, the average BBD RIN generation per company had climbed to over 36 million RINs (23.7 million gallons) annually, more than a 3-fold increase. Only 20 percent of the companies produced less than 1 million gallons of BBD in 2017.
138 
We recognize that the space for other 
advanced biofuels in 2021 will ultimately depend on the 2021 advanced biofuel volume. While EPA is not establishing the advanced biofuel volume for 2021 in this action, we anticipate that the non-cellulosic advanced biofuel volume for 2021, when established, will be greater than 3.65 billion gallons (equivalent to 2.43 billion gallons of BBD, after applying the 1.5 equivalence ratio). This expectation is consistent with our actions in previous years. Accordingly, we expect that the 2021 advanced 
biofuel volume, together with the 2021 BBD volume established today, will continue to preserve a considerable portion of the advanced biofuel volume that could be satisfied by either additional gallons of BBD or by other unspecified and potentially less costly types of qualifying advanced biofuels. 
C. Consideration of Statutory Factors in 
CAA Section 211(o)(2)(B)(ii)(I)–(VI) for 2021 and Determination of the 2021 Biomass-Based Diesel Volume 
As in past annual standard-setting 
rulemakings, we find that additional 
volumes of BBD would displace other advanced biofuel, due to the nested 
VerDate Sep<11>2014 20:53 Feb 05, 2020 Jkt 250001 PO 00000 Frm 00033 Fmt 4701 Sfmt 4700 E:\FR\FM\06FER2.SGM 06FER2lotter on DSKBCFDHB2PROD with RULES27048 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations 
139The BBD volume requirement is nested within 
the advanced biofuel requirement, and the 
advanced biofuel requirement is, in turn, nested within the total renewable fuel volume requirement. See CAA section 211(o)(2)(B)(i)(IV), (II). This means that any BBD produced can be used to satisfy both these other applicable volume requirements even beyond the BBD volume requirement. 
140‘‘Memorandum to docket: Statutory Factors 
Assessment for the 2021 Biomass-Based Diesel (BBD) Applicable Volumes.’’ See Docket EPA–HQ– OAR–2019–0136. 141The 2020 volume requirement for BBD was 
established in the 2019 standards final rule (83 FR 63704, December 11, 2018) 142Letter from Linda Capuano, EIA Administrator 
to Andrew Wheeler, EPA Administrator. October 9, 2019. Available in docket EPA–HQ–OAR–2019– 0136. nature of the standards,139as opposed to 
petroleum fuels. More specifically, for a 
given advanced biofuel standard, greater or lesser BBD volume requirements generally do not change the amount of advanced biofuel used to displace petroleum fuels; the total volume of advanced biofuels is unchanged regardless of the BBD volume requirement. Thus increasing the BBD volume requirement would result in the displacement of other types of advanced biofuels that could have been used to meet the advanced biofuels volume requirement. 
As a result, as in past assessments of 
the factors articulated in CAA 211(o)(2)(B)(ii)(I)–(VI), we consider BBD in comparison to other advanced 
biofuels, and not in comparison to petroleum diesel. Our primary assessment of the statutory factors is that because the BBD requirement is nested within the advanced biofuel volume requirement, we expect that the 2021 advanced volume requirement will determine the level of BBD use, production, and imports that occur in 2021. Therefore, we continue to believe that approximately the same overall volume of BBD would likely be supplied in 2021 regardless of the 2021 BBD volume requirement. In the long- term, however, leaving adequate room for growth of other advanced biofuels could have a beneficial impact on certain statutory factors. Notably, this incentivizes the development of other advanced biofuels with potentially superior cost, climate, environmental, and other characteristics, relative to BBD. We present a detailed analysis of the statutory factors for the BBD volume requirement in a memorandum to the docket.
140 
D. BBD Volume Requirement for 2021 
Based on the above analysis, we are 
setting the applicable volume of BBD at 2.43 billion gallons for 2021. We believe this volume sets the appropriate floor for BBD, and that the volume of BBD actually used in 2021 will be driven by the level of the advanced biofuel and potentially the total renewable fuel standards that the Agency will establish for 2021. In addition, despite providing a significant degree of space for ‘‘other’’ advanced biofuels in recent years, far smaller volumes of ‘‘other’’ advanced have been utilized to meet the advanced standard. The BBD volume we are finalizing today continues to preserve the existing gap between the advanced biofuel volume and the sum of the cellulosic biofuel and BBD volumes. We believe this provides sufficient incentive to producers of ‘‘other’’ advanced biofuels, while also acknowledging that the advanced standard has been met predominantly with biomass-based diesel. Namely, this would allow other advanced biofuels to continue to compete with excess volumes of BBD for market share under the advanced biofuel standard. This would provide significant long term certainty for investments in other advanced biofuels that over time could compete with BBD to fill the advanced biofuel standard. In sum, our assessment of the statutory factors and the implementation of the program supports a volume of 2.43 billion gallons. 
VII. Percentage Standards for 2020 
The renewable fuel standards are 
expressed as volume percentages and 
are used by each obligated party to determine their Renewable Volume Obligations (RVOs). Since there are four separate standards under the RFS program, there are likewise four separate RVOs applicable to each obligated party. Each standard applies to the sum of all non-renewable gasoline and diesel produced or imported. 
Sections II through IV provide our 
rationale and basis for the final volume requirements for 2020.
141The volumes 
used to determine the final percentage standards are shown in Table VII–1. 
TABLE VII–1—V OLUMES FOR USE IN  
DETERMINING THE FINAL 2020 A P-
PLICABLE PERCENTAGE STANDARDS  
[Billion gallons] 
Cellulosic biofuel ....................... 0.59 
Biomass-based diesel .............. 2.43 
Advanced biofuel ...................... 5.09 
Renewable fuel ......................... 20.09 
For the purposes of converting these 
volumes into percentage standards, we generally use two decimal places to be consistent with the volume targets as given in the statute, and similarly two decimal places in the percentage standards. In past years we have used three decimal places for cellulosic biofuel in both the volume requirement and percentage standards to more precisely capture the smaller volume projections and the unique methodology that in some cases results in estimates of only a few million gallons for a group of cellulosic biofuel producers (see Section III for a further discussion of the methodology for projecting cellulosic biofuel production and our decision to round the projected volume of cellulosic biofuel to the nearest 10 million gallons). However, the volume requirements for cellulosic biofuel have increased over time. We have therefore determined that volume requirements and percentage standards for cellulosic biofuel will now use two decimal places. 
In this section, we also discuss our 
regulatory change to the percent standard formulas to account for a projection of the aggregate volume for SREs that we expect to grant for the 2020 compliance year. This section also provides our rationale for that projection of exempt gasoline and diesel volume. Additionally, we also provide our approach for evaluating SREs going forward, including for the currently pending 2019 petitions and for 2020 petitions we receive in the future. 
A. Calculation of Percentage Standards 
The formulas used to calculate the 
percentage standards applicable to 
producers and importers of gasoline and diesel are provided in 40 CFR 80.1405. The formulas rely on estimates of the volumes of gasoline and diesel fuel, for both highway and nonroad uses, which are projected to be used in the year in which the standards will apply. The projected gasoline and diesel volumes are provided by EIA and include projections of ethanol and biomass- based diesel used in transportation fuel.
142Since the percentage standards 
apply only to the non-renewable gasoline and diesel produced or imported, the volumes of renewable fuel are subtracted out of the EIA projections of gasoline and diesel. 
Transportation fuels other than 
gasoline or diesel, such as natural gas, propane, and electricity from fossil fuels, are not currently subject to the standards, and volumes of such fuels are not used in calculating the annual percentage standards. Since under the regulations the standards apply only to producers and importers of gasoline and diesel, these are the transportation fuels 
VerDate Sep<11>2014 20:53 Feb 05, 2020 Jkt 250001 PO 00000 Frm 00034 Fmt 4701 Sfmt 4700 E:\FR\FM\06FER2.SGM 06FER2lotter on DSKBCFDHB2PROD with RULES27049 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations 
143See 75 FR 14670 (March 26, 2010). 
144Under 40 CFR 80.1415(b)(4), renewable diesel 
with a lower heating value of at least 123,500 Btu/ 
gallon is assigned an equivalence value of 1.7. A minority of renewable diesel has a lower heating 
value below 123,500 BTU/gallon and is therefore assigned an equivalence value of 1.5 or 1.6 based on applications submitted under 40 CFR 80.1415(c)(2). 14583 FR 63704 (December 11, 2018). 
146A small refiner that meets the requirements of 
40 CFR 80.1442 may also be eligible for an 
exemption. 
147We adopted this interpretation of our 
regulations in the 2011 final rule. 75 FR 76804. We reaffirmed it in annual rulemakings since then, including most recently in the 2019 final rule. 83 FR 63740; see also, e.g., 77 FR 1320, 1340; 78 FR 
49794, 49825–49826; 80 FR 77420, 77511. We also proposed to follow this interpretation in the July 29 proposal for this final rule. 84 FR 36797 (July 29, 2019). 
148See, e.g., 80 FR 77420, 77511 (December 14, 
2015). 
14984 FR 57677. used to set the percentage standards, as 
well as to determine the annual volume obligations of an individual gasoline or diesel producer or importer under 40 CFR 80.1407. 
As specified in the RFS2 final rule,
143 
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 BBD standard based on biodiesel equivalence. However, all RIN generation is based on ethanol-equivalence. For example, the RFS regulations provide that production or import of a gallon of qualifying biodiesel will lead to the generation of 1.5 RINs. The formula specified in the regulations for calculation of the BBD percentage standard is based on biodiesel-equivalence, and thus assumes that all BBD used to satisfy the BBD standard is biodiesel and requires that the applicable volume requirement be multiplied by 1.5 in order to calculate a percentage standard that is on the same basis (i.e., ethanol-equivalent) as 
the other three standards. However, BBD often contains some renewable diesel, and a gallon of renewable diesel typically generates 1.7 RINs.
144In 
addition, there is often some renewable diesel in the conventional renewable 
fuel pool. As a result, the actual number of RINs generated by biodiesel and renewable diesel is used in the context of our assessment of the applicable volume requirements and associated percentage standards for advanced biofuel and total renewable fuel, and likewise in obligated parties’ determination of compliance with any of the applicable standards. While there is a difference in the treatment of biodiesel and renewable diesel in the 
context of determining the percentage standard for BBD versus determining the percentage standard for advanced biofuel and total renewable fuel, it is not a significant one given our approach to determining the BBD volume requirement. Our intent in setting the BBD applicable volume is to provide a level of guaranteed volume for BBD, but as described in Section VII.B of the 2019 standards final rule, we do not expect the BBD standard to be binding in 
2020.
145That is, we expect that actual 
supply of BBD, as well as supply of conventional biodiesel and renewable diesel, will be driven by the advanced biofuel and total renewable fuel standards and will exceed the BBD standard. 
B. Small Refineries and Small Refiners 
In CAA section 211(o)(9), enacted as 
part of the EPAct, and amended by 
EISA, Congress provided a temporary exemption to small refineries
146 
through December 31, 2010. Congress provided that small refineries could receive a temporary extension of the exemption beyond 2010 based either on the results of a required DOE study, or for the reason of ‘‘disproportionate economic hardship’’ in response to small refinery petitions submitted ‘‘at any time.’’ CAA section 211(o)(9)(B)(i). 
Pursuant to this petition process, EPA 
often granted SREs for a given compliance year after the applicable percentage standards for that compliance year had been established. Under our prior approach to calculating the percentage standards, we did not account for these exemptions in establishing the percentage standards.
147We only accounted for exemptions already granted at the time of the final annual rule.
148 
In the October 28 proposal, we 
proposed to modify the regulations at 40 CFR 80.1405(c) to account for a projection of the total exempted volume of gasoline and diesel produced at small refineries, including for those exemptions granted after the final annual rule.
149We are finalizing the 
change as proposed. The result is that our calculation of the applicable percentage standards for 2020 takes into account a projection of the total exempted volume of gasoline and diesel produced by small refineries in 2020. 
1. Changes to the Projected Volume of 
Gasoline and Diesel for Exempt Small Refineries 
The formulas used to calculate the 
percentage standards applicable to producers and importers of gasoline and diesel are provided in 40 CFR 80.1405(c). The formula for the percentage standard calculation for total renewable fuel, including the definitions of the terms prior to this action, is shown below. The formulas for the other three percentage standards follow the same format, with the numerator of the fraction replaced with the annual volume of cellulosic biofuel, biomass-based diesel, and advanced biofuel, respectively. In this action we are only modifying the definitions of the terms GE
iand DE i, which previously 
referred to the amount of gasoline and diesel projected to be produced by exempt small refineries, to now refer to the amount of gasoline and diesel projected to be exempt. All other terms remain in the same and were not reexamined in this rulemaking.

i= The amount of diesel fuel projected to 
be produced by exempt small refineries and small refiners in year i, in gallons, in any year they are exempt per §§ 80.1441 and 80.1442. 
Historically, EPA has interpreted the 
terms GE iand DE ito refer to the amount 
of gasoline and diesel projected to be 
produced by small refineries that have already been granted exemptions from their RFS obligations prior to our issuing the final rule for the relevant compliance year.
150As a result of this 
interpretation, any SREs granted after we issued the annual rule containing the percentage standards for that year effectively reduced the required volume of renewable fuel for that year. For example, in August 2019 we granted 31 SREs for the 2018 compliance year after the percentage standards for 2018 had been established.
151These SREs 
reduced the obligated volume of gasoline and diesel for 2018 by 13.42 billion gallons, effectively reducing the required volume of total renewable fuel for 2018 by 1.43 billion RINs. 
In comments on the July 29 proposal, 
many commenters requested that EPA adopt a different interpretation of the terms for the amount of gasoline and diesel projected to be produced by exempt small refineries in the existing percentage standard formula.
152Many 
commenters requested that these terms refer to a projection of the exempted volume of gasoline and diesel produced by small refineries, regardless of whether EPA had already adjudicated such exemption petitions by the time of the final rule. These commenters argued that this interpretation of the regulations is reasonable and better implements the statutory requirement that EPA must ‘‘ensure’’ the renewable fuel volumes are met. Some commenters suggested that adjusting the percentage standards formula is more important now than in 
earlier years of the program as we have recently granted exemptions for more significant volumes of gasoline and diesel, potentially resulting in more significant volumes that are not being met at the time of compliance.
153A 
petition for administrative reconsideration raised similar issues, asking EPA to reconsider our approach for accounting for exempted volumes through the formula at 40 CFR 80.1405(c).
154In the October 28 
proposal, EPA undertook a process to revisit this issue, albeit under our inherent authority to revise or amend a rulemaking, rather than as an exercise of our reconsideration authority under CAA section 307(d)(7)(B).
155 
In the October 28 proposal we 
proposed to change the definitions of the two relevant terms in the percentage standard formula at 40 CFR 80.1405(c), GE
iand DE i. We proposed that these 
terms represent a projection of the exempted volume of gasoline and diesel, regardless of whether we had adjudicated exemptions for that year by the time of the final rule establishing the percentage standards. We are finalizing these changes, and in turn, also completing the process of revisiting this issue that we undertook as described above in response to the above-noted administrative petition. The term ‘‘GE
i’’, 
representing the volume of exempt gasoline, is now defined as ‘‘the total amount of gasoline projected to be exempt in year i, in gallons, per §§ 80.1441 and 80.1442.’’ Similarly, the term ‘‘DE
i’’, representing the volume of 
exempt diesel, is now defined as ‘‘the total amount of diesel projected to be exempt in year i, in gallons, per §§ 80.1441 and 80.1442.’’ 
We begin by explaining our legal 
authority to adopt the new definitions, as well as our rationale for the change in our policy. While the statute does not specifically require EPA to redistribute exempted volumes in this manner, we believe that this is a reasonable 
interpretation of our authority under Chevron v. NRDC.
156Indeed, making 
this projection harmonizes various statutory provisions. The statute authorizes small refineries to petition for and EPA to grant an exemption based on disproportionate economic hardship ‘‘at any time,’’
157while also 
directing EPA to promulgate standards by November 30 of the prior year to ‘‘ensure[]’’ that the renewable fuel volumes are met.
158In other words, 
small refineries may seek and EPA may grant hardship exemptions at any time, including after the percentage standards are established. Meanwhile, EPA may account for a projection of these exemptions in the annual rule to ‘‘ensure’’ the renewable fuel volumes.
159 
In more concrete terms, should EPA 
grant SREs without accounting for them in the percentage formula, those exemptions would effectively reduce the volumes of renewable fuel required by the RFS program, potentially impacting renewable fuel use in the U.S.
160By contrast, under our new 
approach, the percentage standard for each category of renewable fuel would increase to account for a projection of the exempted volume. These higher percentage standards would have the effect of ensuring that the required volumes of renewable fuel are met when small refineries are granted exemptions from their 2020 obligations after the issuance of the final rule, provided EPA’s projection of the exempted volume is accurate. 
This new approach entails a change in 
policy.
161We previously did not 
account for exemptions granted after the annual rule, and at times we even suggested that doing so was improper.
162We believe our changed 
approach is appropriate and largely avoids the problems we previously identified. First, we had previously stated that ‘‘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 parties regarding their

167The actual required volume is subject to other 
uncertainties besides small refinery exemptions, such as unexpected changes in gasoline and diesel use. 168Other factors, such as judicial resolution of 
pending decisions or subsequent Congressional 
direction, could potentially affect EPA’s SRE policy going forward.

Congress in this Statement directed 
DOE, under certain circumstances, ‘‘to recommend to the EPA Administrator a 50 percent waiver of RFS requirements for the [small refinery] petitioner.’’ Id. at 35. Consistent with that guidance 
and since 2014, DOE has recommended 50 percent exemptions as it deemed appropriate.

This guidance, read together with 
that discussed in the previous footnote, supports the interpretation that DOE has authority to recommend partial exemptions for particular small refineries, and that EPA has discretion to follow that recommendation and grant a partial exemption. 
171‘‘Decision on 2018 Small Refinery Exemption 
Petitions,’’ Memorandum from Anne Idsal, Acting Assistant Administrator, Office of Air and Radiation to Sarah Dunham, Director, Office of Transportation and Air Quality. August 9, 2019 (‘‘August 9 Memorandum Decision’’). 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.’’
163Today’s changes 
are consistent with these views. By projecting exempted volumes in advance of issuing annual standards, we can issue a single set of standards for each year without the need for periodic revisions and the associated uncertainty for obligated parties. 
Second, we also had previously noted 
that ‘‘Congress allowed for some imprecision to exist in the actual volumes of renewable fuel that are consumed as a result of the percentage standards that we set each November.... ’ ’
164Relatedly, we had 
noted the inherent difficulties of projecting exempted small refinery volumes.
165We still agree that Congress 
allowed for some imprecision to exist in the actual required volumes of renewable fuel, and that projecting future exempted volumes involves some uncertainty. 
But several recent developments 
persuade us to reach a different conclusion in accounting for a projection of exempted small refinery volumes. For one, we are projecting the aggregate exempted volume in 2020. We 
thus need not wrestle with the difficulties of predicting precisely which refineries will apply or the economic circumstances of specific refineries in 2020. We only need to estimate the total exempted volume. Moreover, we have the benefit of additional experience administering the RFS program and knowledge of the relatively high levels of exempted volumes in recent years, where exempted volumes associated with SREs granted after the annual percentage standards were established have constituted a significant portion of the total volume of obligated fuel, resulting in fewer RINs being used to comply with the RFS standards. 
Finally, in recent annual rulemakings, 
EPA has not articulated its prospective policy to adjudicating SRE petitions for those compliance years. For instance, in the 2018 final rule, we did not state our policy to adjudicating 2018 SRE petitions. Instead we articulated that policy in a separate memorandum issued after the annual rule.
166Since EPA’s policy to adjudicating SRE 
petitions affects the exempted volume, not having established this policy at the time of the annual rule made it very challenging to project the exempted volume. In today’s rule, by contrast, we are articulating our prospective policy to adjudicating SRE petitions (beginning with the 2019 SRE petitions and including the 2020 SRE petitions) concurrently with issuing this final rule. Doing so augments our ability to reasonably project the exempted volume for 2020. We explain this policy further below. 
2. Projecting the Exempted Volume of 
Gasoline and Diesel in 2020 
As already noted, we acknowledge the 
inherent uncertainty in projecting the exempted volume. More concretely, an imprecise projection has consequences on the actual required volume of renewable fuel. If we over-project the volume of gasoline and diesel produced by exempt small refineries in 2020, the actual required volumes of renewable fuel will be higher than the volumes used in calculating the percentage standards. By contrast, if we under- project the volume of exempted gasoline and diesel, the actual required volumes of renewable fuel will be lower than the volumes used in calculating the percentage standards. If we project the volume correctly, we will ensure that, as far as exempted small refinery volumes are concerned, the actual required volume is equal to the volume established in this final rule.
167 
In selecting the methodology for 
projecting the exempted volume, we thus aim to make a neutral projection of exemptions based on the information now before us. As proposed, we are finalizing a projection methodology based on a 2016–18 annual average of exempted volumes had EPA strictly followed DOE recommendations in those years, including by granting 50 percent relief where DOE recommended 50 percent relief. We explain why we do so below, beginning with our decision to base the projection on DOE 
recommendations and then our decision to use a 2016–18 annual average. Finally, we state the projected exempt volumes of gasoline and diesel based on this approach and the corresponding number of RINs. 
First, we choose to base the projection 
of exempted volumes on DOE’s recommendations for two reasons, one prospective and one retrospective. 
Prospectively, this is our general approach to adjudicating SRE petitions going forward, beginning with 2019 SRE petitions and including 2020 SRE petitions. Our approach to evaluating SREs going forward is to follow DOE’s recommendations, including granting partial (i.e., 50 percent) exemptions, 
where appropriate. The statute authorizes EPA to evaluate petitions for SREs considering DOE’s study, recommendation, and other economic factors. While final decisions on 2020 SREs must await EPA’s receipt and adjudication of those petitions, we generally have the statutory authority to issue a final decision consistent with DOE’s recommendation.
168This reading 
of the statute is consistent with congressional guidance to DOE
169and 
EPA.170 
We acknowledge that on August 9, 
2019, we took final agency action on 36 then-pending small refinery petitions for the 2018 compliance year (‘‘August 9 Memorandum Decision’’),
171and 
stated that the ‘‘best interpretation’’ of the statute was that EPA should either grant or deny petitions in full, and ‘‘not

and the volume of RINs not required to be retired

exemptions. 
180To date, we have adjudicated all 2018 small 
refinery exemption petitions submitted to us. EPA 
has not yet adjudicated any small refinery exemptions for the 2019 or 2020 compliance years. grant partial relief.’’ Specifically, we 
observed that the statute provided for exemptions as an ‘‘extension of the exemption under subparagraph (A)’’, where subparagraph (A) stated that the RFS program requirements ‘‘shall not apply to small refineries under calendar year 2011.’’
172We had implemented the 
‘‘subparagraph (A)’’ pre-2011 exemption as a full exemption for all qualifying small refineries. Consistent with this interpretation, we concluded that ‘‘when Congress authorized the Administrator to provide an ‘extension’ of that exemption for the reason of [disproportionate economic hardship], Congress intended that extension to be a full, and not partial, exemption.’’
173 
We believe, however, that this is not 
the only reasonable way to adjudicate exemption petitions. Had Congress spoken directly to the issue of the amount of relief EPA could provide to small refineries, EPA would be bound by that directive. However, the statute is silent with respect to EPA’s authority to issue partial exemptions. Nothing in the statute directly addresses this issue. No statutory language exists characterizing the scope of an exemption; there are no terms employed such as ‘‘partial’’ or ‘‘full,’’ or ‘‘50%’’ or ‘‘100%.’’ Moreover, nothing in the statute obligates EPA to provide full relief where we find that only partial relief is warranted. 
We think there is another reasonable 
reading of this provision of the statute: EPA may issue partial exemptions. Notably, EPA may determine that only partial relief is warranted based on a particular small refinery’s circumstances. In that case, it is reasonable for the level of relief that EPA grants to reflect that determination. For purposes of making the projection of the aggregate exempted volume of gasoline and diesel in 2020, and going forward, we are adopting this interpretation of the statute,
174and 
thereby depart from the interpretation taken in the August 9 Memorandum Decision, under which EPA ‘‘shall either grant or deny petitions for small refinery hardship in full, and not grant partial relief.’’
175We adopt this new 
approach for several reasons, consistent with FCC v. Fox Television Stations, 
Inc.
176 
As already noted, this new policy 
would allow EPA to ensure that the level of relief that it grants appropriately reflects the particular small refinery’s disproportionate economic hardship. This allows EPA to more precisely calibrate its RFS policy, and to strike an appropriate balance between furthering the production and use of renewable fuels while granting relief to small refineries that meet the statutory criteria. This balance, moreover, is also appropriate in light of the above-cited recent Congressional direction.
177 
Even independent of our prospective 
SRE policy, we believe this approach is a reasonable estimate of the aggregate exempted volume based on a retrospective review of EPA’s past SRE policies. In prior years, EPA has taken different approaches in evaluating small refinery petitions. As noted above, in the August 9 Memorandum Decision, we granted full exemptions to petitioners where DOE either recommended full or 50 percent relief. That is, in cases where DOE found a small refinery experienced either disproportionate impacts or viability impairment, EPA found the small refinery experienced disproportionate economic hardship and granted a full exemption. By contrast, in earlier years of the program, we denied petitions and provided no exemption in certain cases where DOE recommended a 50 percent exemption, finding that disproportionate economic hardship existed only where the small refinery experienced both disproportionate impacts and viability impairment.
178 
Our approach to projection, then, takes a middle ground between these prior approaches, and is a reasonable estimate of the aggregate exempted volume in 2020. 
We now turn to our decision to use 
the 2016–18 annual average under this methodology. As we have not yet received SRE petitions for 2020, we must estimate the aggregate amount of DOE recommended relief for that year. To do so, it is instructive to look back at what the exempted volumes of gasoline and diesel in previous years would have been had EPA followed DOE’s recommendations, including granting partial exemptions. These volumes, along with the Renewable Volume Obligation (RVO) that would have been exempted, are shown in Table VII.B–1. 
TABLE VII.B–1—E STIMATED EXEMPTED VOLUME OF GASOLINE AND DIESEL AND ESTIMATED RVO E XEMPTED BY  
COMPLIANCE YEARFOLLOWING DOE’ SRECOMMENDATIONS

2018 ......................................................................................................... 4,620 3,270 840 
As demonstrated in Table VII.B–1, the 
volume of gasoline and diesel that 
would have been exempted if EPA had followed DOE’s recommendations has varied significantly in previous years.
179 
This is because there are many factors that affect the number of SREs that are granted in a given year and the aggregate exempted volume. We believe that it is appropriate to use an average volume of the gasoline and diesel that would have been exempted over a three-year period as our projection of gasoline and diesel that will be exempted in 2020, rather than the volume of gasoline and diesel that would have been exempted in any single year. This approach averages out the effects of unique events or market circumstances that occurred in individual past years that may or may not occur in 2020. Given that the last year for which we have data on small refinery exemptions is 2018,
180we take 
the average exempted volume from 2016–18.

would have been exempted in 2016–18

181To determine the 49-state values for gasoline 
and diesel, the amount of these fuels used in Alaska 
is subtracted from the totals provided by EIA because petroleum based fuels used in Alaska do not incur RFS obligations. The Alaska fractions are determined from the June 28, 2019 EIA State Energy Data System (SEDS), Energy Consumption Estimates.

‘‘aggregate compliance’’ approach for the United States in annual RFS rulemakings since establishing it in the 2010 RFS2 rule. See 75 FR 14701–04. In this annual rulemaking, we have not reexamined or 
reopened this policy, including the regulations at 80.1454(g) and 80.1457. Similarly, as further explained below, we have applied this approach for 
Canada since our approval of Canada’s petition to use aggregate compliance in 2011. In this rulemaking, we have also not reexamined or reopened our decision on that petition. Any comments on these issues are beyond the scope of this rulemaking. if EPA had followed DOE’s 
recommendations is 4,240 and 3,020 million gallons, for gasoline and diesel fuel, respectively. We use these values for GE
iand DE i, respectively, in 
calculating the percentage standards for each of the renewable fuel types. We also note that these exempted volumes would have resulted in an average reduction to the RVO of approximately 
770 million RINs. 
C. Final Standards
The formulas in 40 CFR 80.1405 for
the calculation of the percentage 
standards require the specification of a total of 14 variables covering factors such as the renewable fuel volume requirements, projected gasoline and diesel demand for all states and territories where the RFS program applies, renewable fuels projected by EIA to be included in the gasoline and diesel demand, and projected gasoline and diesel volumes from exempt small refineries. The values of all the variables used for this final rule are shown in Table VII.C–1 for the applicable 2020 standards.

VIII. Administrative Actions
A. Assessment of the Domestic
Aggregate Compliance Approach
The RFS regulations specify an 
‘‘aggregate compliance’’ approach for demonstrating that planted crops and crop residue from the U.S. complies with the ‘‘renewable biomass’’ requirements that address lands from which qualifying feedstocks may be harvested.
184In the 2010 RFS2 
rulemaking, EPA established a baseline number of acres for U.S. agricultural land in 2007 (the year of EISA enactment) and determined that as long as this baseline number of acres was not exceeded, it was unlikely that new land outside of the 2007 baseline would be devoted to crop production based on historical trends and economic considerations. The regulations specify, therefore, that renewable fuel producers using planted crops or crop residue from the U.S. as feedstock in renewable fuel production need not undertake individual recordkeeping and reporting related to documenting that their feedstocks come from qualifying lands, unless EPA determines through one of its annual evaluations that the 2007 baseline acreage of 402 million acres agricultural land has been exceeded. 
In the 2010 RFS2 rulemaking, EPA 
committed to make an annual finding concerning whether the 2007 baseline amount of U.S. agricultural land has been exceeded in a given year. If the baseline is found to have been exceeded, then producers using U.S. planted crops and crop residue as feedstocks for renewable fuel production would be required to comply with individual recordkeeping and reporting requirements to verify

185USDA also provided EPA with 2019 data from 
the discontinued Grassland Reserve Program (GRP) 
and Wetlands Reserve Program (WRP). Given this data, EPA estimated the total U.S. agricultural land both including and omitting the GRP and WRP acreage. In 2019, combined land under GRP and WRP totaled 2,974,573 acres. Subtracting the GRP, WRP, and Agriculture Conservation Easement Program acreage yields an estimate of 376,853,632 acres or approximately 376.9 million total acres of U.S. agricultural land in 2019. Omitting the GRP and WRP data yields approximately 379.8 million acres of U.S. agricultural land in 2019.

Specific comments relevant to the provisions that were under consideration for finalization in this action have also been added to the docket for this action (Docket Item No. EPA– HQ–OAR–2019–0136–0002). We are only responding to comments from the REGS proposal on the provisions that are being finalized in this action. Comments on the remaining provisions in the REGS proposal, as well as those on provisions listed in the July 29 proposal but that are not being finalized here, remain under consideration. We are not responding to them in this action.

Based on data provided by the USDA 
Farm Service Agency (FSA) and Natural Resources Conservation Service (NRCS), we have estimated that U.S. agricultural land reached approximately 379.8 million acres in 2019 and thus did not exceed the 2007 baseline acreage of 402 million acres. The USDA data used to make this derivation can be found in the docket to this rule.
185 
B. Assessment of the Canadian Aggregate Compliance Approach 
The RFS regulations specify a petition 
process through which EPA may approve the use of an aggregate compliance approach for planted crops and crop residue from foreign countries.
186On September 29, 2011, 
EPA approved such a petition from the Government of Canada.
187 
The total agricultural land in Canada 
in 2019 is estimated at 118.1 million 
acres. This total agricultural land area includes 95.9 million acres of cropland and summer fallow, 12.4 million acres of pastureland and 9.8 million acres of agricultural land under conservation practices. This acreage estimate is based on the same methodology used to set the 2007 baseline acreage for Canadian agricultural land in EPA’s response to Canada’s petition. The data used to make this calculation can be found in the docket to this rule. This acreage does not exceed the 2007 baseline acreage of 122.1 million acres. 
IX. Amendments to the RFS and Fuels 
Program Regulations 
In implementing the RFS program, we 
have identified several changes to the program that will assist with implementation in future years. These regulatory changes include both revisions we proposed in the July 29 proposal—clarification of diesel RVO calculations, pathway petition conditions, a biodiesel esterification pretreatment pathway, distillers corn oil and distillers sorghum oil pathways, and renewable fuel exporter provisions—and certain provisions of 
the 2016 REGS rule proposal that we are finalizing here.
188These regulatory 
changes are described in this section. Comments on these regulatory revisions from both the 2016 REGS and 2020 RVO proposals, as well as EPA’s responses, are contained in the response to comments (RTC) document in the docket for this action.

regarding clarification of diesel RVO 
calculations. Specifically, we are finalizing the ‘‘primary approach’’ proposed in the July 29 proposal, with some modifications based on comments 
received. We are not finalizing either of the two alternative approaches presented in the July 29 proposal, after consideration of negative comments on these two approaches. 
Historically, home heating oil (HO) 
and diesel fuel were virtually indistinguishable because both contained the same distillation range of hydrocarbons and high level of sulfur. EPA’s diesel fuel sulfur regulations resulted in a distinction in the marketplace beginning in the 1990s and concluding in 2010 with the phase-in of the ultra-low sulfur diesel regulations for diesel fuel used in motor vehicles and motor vehicle engines (MV diesel fuel). Similarly, beginning in 2004, EPA promulgated requirements for diesel fuel used in nonroad, locomotive, and marine vehicles and engines (NRLM diesel fuel) that concluded phasing in at the end of 2014. Thus, all diesel fuel for use in motor vehicles and motor vehicle engines, and nonroad, locomotive, and marine vehicles and engines, is currently required to meet a 15 ppm sulfur per-gallon standard, under regulations set out in 40 CFR part 80, subpart I
190(For purposes of subpart I, such diesel fuel is also now collectively 
known as MVNRLM diesel fuel). We did not set standards for HO under subpart I, with the result that it remained high in sulfur content and cost less to produce than MVNRLM diesel fuel. As such, subpart I also requires all parties in the distribution system to ensure that diesel fuel containing 15 ppm sulfur or less (referred to as 15 ppm diesel fuel, ultra-low sulfur diesel fuel, or ULSD) remains segregated from higher sulfur fuels and to take measures to prevent sulfur contamination of ULSD.
191 
The RFS regulations, which place an 
RVO on the production and importation of diesel transportation fuel, but not on the production or importation of HO, were promulgated in 2010 and, similar to subpart I regulations, made the same presumption that HO and MVNRLM diesel fuel would be segregated. The RFS regulations did not anticipate that these fuels would become indistinguishable, have the same value in the marketplace (apart from their RFS compliance cost), and be commingled in the fuel distribution system. For example, 40 CFR 80.1407 set forth requirements for obligated parties to include all products meeting the definition of MVNRLM diesel fuel, collectively called ‘‘diesel fuel,’’ at 40 CFR 80.2(qqq) that are produced or imported during a compliance period in the volume used to calculate their RVOs unless the diesel fuel is not transportation fuel.
192Under definitions 
of MV and NRLM diesel fuel, these products include diesel fuel that is ‘‘made available’’ for use in motor vehicles and motor vehicle engines, and nonroad, locomotive, or marine vehicles and engines.
193 
When the RFS regulations were 
promulgated in 2010, the lower production cost of HO relative to diesel fuel provided economic incentive for refiners, pipelines, and terminals to produce and distribute HO separately from diesel fuel. After we promulgated the RFS regulations, however, many states began implementing programs designed to reduce the sulfur content of HO to 15 ppm or less (15 ppm HO). Currently, the majority of HO is required to meet a 15 ppm sulfur standard under numerous state and city programs in the Northeast and Mid- Atlantic,
194making HO once again 
indistinguishable from ULSD and of the same economic value as MVNRLM

195See the New England Fuel Institute’s (NEFI) 
‘‘State Sulfur & Bioheat Requirements for No. 2 
Heating Oil in the Northeast & Mid-Atlantic States,’’ available in the docket for this action. 
196See 40 CFR 80.610(e)(6). ECA marine fuel is 
not transportation fuel under the RFS regulations. Therefore, refiners and importers do not incur an RVO for ECA marine fuel that they produce or import. 
197See 40 CFR 80.2(y) and (nnn). 
198We have received requests from a number of 
regulated parties asking the agency to amend the fuels regulations to allow parties to more easily mix and fungibly ship HO, ECA marine fuel, and MVNRLM fuel that meet the 15 ppm sulfur standard. In a separate action, we intend to propose additional amendments that would significantly streamline these regulations (see RIN 2060–AT31 in EPA’s Regulatory Agenda). 199A similar situation exists with respect to #1 
diesel fuel, which is used/blended in the winter due to cold temperature constraints and its often- identical counterparts of kerosene and jet fuel. 
200See 40 CFR 80.1407(f)(8). 
201With the other exceptions listed in 40 CFR 
80.1407(f). diesel fuel.195Further, in 2015, 
additional regulations became effective 
that required marine diesel fuel used in Emissions Control Areas (ECA marine fuel) to contain 1,000 ppm sulfur or less.
196In response, many companies 
have opted to produce and distribute ECA marine fuel containing 15 ppm sulfur or less (15 ppm ECA marine fuel) fungibly with 15 ppm diesel fuel, rather than invest in infrastructure to distribute and segregate higher-sulfur ECA marine fuel. Since HO, ECA marine fuel, and other non-transportation fuels that meet a 15 ppm sulfur standard are essentially identical in the marketplace, we believe that some parties in the fuel distribution system are distributing them together—i.e., commingling 
MVNRLM diesel fuel with 15 ppm HO and 15 ppm ECA marine fuel. 
The regulations in 40 CFR part 80, 
subpart I, do not prohibit parties from commingling MVNRLM diesel fuel with other 15 ppm distillate fuel (i.e., distillate fuel that contains 15 ppm sulfur or less) that is designated for non- transportation purposes. However, commingled fuel must meet all of the applicable requirements in subpart I because the resulting fuel is ‘‘made 
available’’ for use in motor vehicles, or nonroad, locomotive, or marine vehicles and engines.
197This means that any 
refiner or importer that produces or imports 15 ppm distillate fuel that is designated for non-transportation purposes and is commingled with MVNRLM diesel fuel must also certify the fuel as meeting the sampling, testing, reporting, and recordkeeping requirements in subpart I.
198 
Although this approach does not 
create compliance issues relating to subpart I requirements, at proposal we explained that we were concerned that some obligated parties (e.g., refiners and 
importers) under the RFS program may be calculating RVOs without accounting for all of their 15 ppm distillate fuel that is ultimately sold for use as MVNRLM diesel fuel. Specifically, obligated parties may be excluding 15 ppm HO or 
15 ppm ECA marine fuel from their RVO calculations, and downstream parties may be re-designating this fuel as MVNRLM diesel fuel and not incurring an RVO.
199 
We also explained that with the 
convergence of the MVNRLM diesel fuel, HO, and ECA marine fuel sulfur standards, some stakeholders had expressed confusion to EPA on accounting for 15 ppm distillate fuel that leaves the obligated party’s gate designated as HO, ECA marine fuel, or other non-transportation fuels, but is subsequently re-designated as either MVNRLM diesel fuel or ultimately used as MVNRLM diesel fuel by a downstream entity. Specifically, some obligated parties had asked whether they are required to add re-designated MVNRLM diesel fuel back to their RVO calculations while some downstream entities had asked whether they are required to incur an RVO for MVNRLM diesel fuel they re-designate from non- transportation fuel to transportation fuel. 
We further explained in the July 29 
proposal that we intended for any diesel fuel not used as transportation fuel, such as HO or ECA marine fuel, to be excluded from RVO calculations in keeping with statutory requirements.
200 
We also intended for all diesel fuel ultimately used as transportation fuel to incur an RVO, even 15 ppm distillate fuel that is initially designated as non- transportation fuel and subsequently re- designated as transportation fuel by downstream parties.
201Thus, existing 
regulations allow downstream parties who are registered as refiners and who comply with all sampling, testing, recordkeeping, and other refiner requirements to ‘‘produce’’ MVNRLM diesel fuel from HO, ECA marine fuel, and other non-transportation fuels. These refiners incur RVOs for all MVNRLM diesel fuel that they ‘‘produce’’ from the non-transportation fuel. However, we believe that stakeholder confusion over who should account for re-designated fuel in their RVO may be causing the omission of some re-designated MVNRLM diesel fuel from RVO calculations altogether. Therefore, we are revising the RFS regulations to more clearly specify how volumes of re-designated MVNRLM diesel fuel are accounted for in obligated parties’ RVO calculations in order to ensure that the RFS mandates continue to be met. 
Consistent with our proposal, we are 
clarifying the requirement for refiners and importers to include distillate fuel in their RVO compliance calculations and providing exceptions for the following three additional categories of fuel: 
•Distillate fuel, such as HO or ECA 
marine fuel, with a sulfur content greater than 15 ppm that is clearly designated for a use other than transportation fuel. 
•Distillate fuel that meets the 15 
ppm sulfur standard, that is designated 
for non-transportation use, and that remains completely segregated from MVNRLM diesel fuel from the point of production through to the point of use for a non-transportation purpose. 
•Distillate fuel that meets the 15 
ppm diesel sulfur standard, that is ultimately used for non-transportation purposes, and that does not remain completely segregated from MVNRLM diesel fuel. 
As also explained in the July 29 
proposal, since the first two categories of distillate fuel above are completely segregated from MVNRLM diesel fuel, we do not believe that they would be used as transportation fuel and are therefore not finalizing any additional requirements for these fuels to be excluded from a refiner or importer’s RVO compliance calculations. However, consistent with the July 29 proposal, and as described below, because the third category of distillate fuel is not completely segregated and is indistinguishable from MVNRLM diesel fuel, we are finalizing additional requirements for this type of distillate fuel to be excluded from a refiner or importer’s RVO compliance calculations. 
2. Downstream Re-Designation of 
Certified Non-Transportation 15 ppm Distillate Fuel to MVNRLM Diesel Fuel 
Consistent with the July 29 proposal, 
and in order to allow refiners and importers to exclude distillate fuel that that meets the 15 ppm diesel sulfur standard, is ultimately used for non- transportation purposes, and does not remain completely segregated from MVNRLM diesel fuel from their RVO calculations, we are establishing a new category of distillate fuel: Certified non- transportation 15 ppm distillate fuel (‘‘certified NTDF’’). We are defining certified NTDF as distillate fuel that meets all of the following requirements: 
•Fuel that is certified as complying 
with the 15 ppm sulfur standard, cetane/aromatics standard, and all applicable sampling, testing, and 
VerDate Sep<11>2014 20:53 Feb 05, 2020 Jkt 250001 PO 00000 Frm 00041 Fmt 4701 Sfmt 4700 E:\FR\FM\06FER2.SGM 06FER2lotter on DSKBCFDHB2PROD with RULES27056 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations 
recordkeeping requirements of 40 CFR 
part 80, subpart I. 
•Fuel that is designated on the 
product transfer document as 15 ppm HO, 15 ppm ECA marine fuel, or other non-transportation fuel (e.g., jet fuel, 
kerosene, No. 4 fuel, or distillate fuel for export only) with a notation that the fuel is ‘‘15 ppm sulfur (maximum) certified NTDF—This fuel is designated for non-transportation use.’’ with no designation as MVNRLM diesel fuel. 
Some commenters noted that our 
proposed PTD language stating, ‘‘This fuel meets all MVNRLM diesel fuel standards’’ could potentially cause confusion as to whether the fuel qualified as MVNRLM diesel fuel or not. We are therefore finalizing PTD 
language similar to that suggested by commenters, which avoids any reference to MVNRLM diesel fuel. 
In order to prevent refiners and 
importers from circumventing the requirement to incur an RVO for all transportation fuel by simply designating transportation fuel as non- transportation fuel, we had proposed that refiners or importers must have a reasonable expectation that their NTDF will be used as HO, ECA marine fuel, or another non-transportation purpose in order to exclude it from their RVO calculations. We proposed that refiners or importers would need to meet the following three criteria to demonstrate they have a reasonable expectation that NTDF will not be used as transportation fuel: 
•The refiner or importer supplies 
areas that use HO, ECA marine fuel, or 15 ppm distillate fuel for non- transportation purposes in the quantities being supplied by the refiner or importer. 
•The refiner or importer has entered 
into a contractual arrangement that prohibits the buyer from selling the fuel as MVNRLM diesel fuel. 
•The volume of fuel designated as 
HO, ECA marine fuel, or other non- transportation purposes is consistent with the refiner’s or importer’s past practices or reflect changed market conditions. 
We also noted that EPA may consider 
any other relevant information in assessing whether a refiner or importer has a reasonable expectation that the fuel was used for non-transportation purposes. 
We received comments indicating that 
it would be complex and disruptive to require refiners and importers to enter into contractual arrangements that prohibit the buyers from selling NTDF as MVNRLM diesel fuel. We agree with these comments and have eliminated this criterion. In light of these comments and in order to simplify the proposed 
regulations, we have also consolidated the first and third criterion into one sentence that states ‘‘[t]o establish a reasonable expectation that the fuel will be used for non-transportation purposes, a refiner or importer must, at a minimum, be able to demonstrate that they supply areas that use heating oil, ECA marine fuel, or 15 ppm distillate fuel for non-transportation purposes in quantities that are consistent with past practices or changed circumstances.’’ With these changes, we are finalizing the requirement that refiners or importers may only exclude NTDF from their compliance calculations if they have a reasonable expectation that the fuel will be used for non-transportation purposes. 
Some commenters also noted that 
there is normally a noticeable price difference between fuel sold for transportation fuel and non- transportation fuel, and that this price difference is a relevant consideration for determining if the fuel was intended to be sold as transportation fuel or non- transportation fuel. We agree with this comment and the final rule explicitly identifies price as relevant information that EPA may consider in evaluating whether a refiner or importer had a reasonable expectation that the fuel will be sold for non-transportation purposes. 
As previously noted, our intent is to 
ensure that all fuel ultimately used as MVNRLM diesel fuel incurs an RVO. In order to achieve this goal, we are also finalizing requirements that will allow parties in the fuel distribution system (e.g., downstream of the original 
refinery or import facility) to sell certified NTDF as MVNRLM diesel fuel without incurring an RVO if the total volume of MVNRLM diesel fuel delivered during each compliance period does not exceed the amount of MVNRLM diesel fuel received during that compliance period. Any party who re-designates certified NTDF as MVNRLM diesel fuel is a refiner for purposes of the RFS program and is therefore required to register as a refiner. They will also be required to calculate whether the volume of MVNRLM diesel fuel that they deliver exceeds the volume of MVNRLM diesel fuel that they receive, during an annual compliance period. If a downstream party delivers a volume of MVNRLM diesel fuel that exceeds the volume of MVNRLM diesel fuel they received during a compliance period, they are required to treat the difference as diesel fuel that they ‘‘produced’’ and incur an RVO on this volume. This will enable 
proper accounting for the aggregate volume of non-transportation fuel that is re-designated as MVNRLM diesel fuel 
under the RFS program. This one-sided test allows MVNRLM diesel fuel to be sold as HO or ECA marine fuel but prevents the erosion of the renewable fuel mandate. These parties will also be subject to recordkeeping requirements to ensure the enforceability of this program. 
We received several comments 
recommending modifications and clarifications to the proposed volume balance provisions, and are finalizing the following changes in response to these comments: 
•We are adding an equation to the 
regulations that provides specific guidance on how to calculate the volume balance. This is in response to a comment suggesting that EPA should include a balance equation for diesel fuel, similar to the heating oil balance in 40 CFR 80.599(c)(3) and (4). The new balance equation accounts for changes in diesel inventory, in addition to diesel volumes in and out. 
•We are clarifying that the volume 
balance requirement applies to each facility that is registered as a diesel refinery. This is in response to comments suggesting that EPA clarify whether the volume balances were applicable on a facility basis or an aggregated basis. Our intent was that the balances apply on a facility basis and have clarified this in the final regulations. 
One commenter also recommended 
that the new provisions for redesignation of certified NTDF to MVNRLM diesel fuel should apply to the owner of the certified NTDF at the time of redesignation and not the custody holder of the certified NTDF, or the original refiner of the NTDF. We 
agree with this recommendation and have included final rule requirements that reflect this recommendation. Since the owner of certified NTDF would be responsible for making any decisions regarding redesignation of NTDF to MVNRLM diesel fuel, we intend for the owner of the certified NTDF to meet the regulatory requirements associated with redesignation, such as registration, reporting, and incurring an RVO. 
We are also finalizing corresponding 
reporting requirements, including requiring refiners and importers to report the volume of MVNRLM diesel fuel they produce or import, the volume of distillate fuel they produce or import that is not transportation fuel, and the volume of distillate fuel they produce or import that is certified NTDF. We are also requiring some downstream parties who redesignate NTDF as MVNRLM diesel fuel to submit reports to EPA identifying the volume of MVNRLM

202See 40 CFR 80.1426(a)(1)(i). 
203See 40 CFR 80.1431(a)(ix). 204While we expect these pathways to be used 
predominately for biodiesel, they may also be used 
for heating oil and jet fuel. Renewable diesel is excluded because it is by definition ‘‘not a mono- alkyl ester’’ (40 CFR 80.1401) and that is what transesterification produces. 
205Commonly used base catalysts include sodium 
hydroxide (NaOH), potassium hydroxide (KOH) and sodium methoxide (NaOCH
3). diesel fuel received, the volume of 
MVNRLM diesel fuel delivered, the volume of fuel re-designated from certified NTDF to MVNRLM diesel fuel, and the volume of MVNRLM diesel fuel redesignated to non-transportation use. Further, for purposes of evaluating compliance, we are also: 
•Requiring parties who re-designate 
certified NTDF to MVNRLM diesel fuel to keep all records relating to these transactions. 
•Prohibiting a party from exceeding 
its balance requirements without incurring an RVO. 
•Ensuring that the attest auditors 
review relevant information to ensure compliance with applicable RFS program requirements. 
Some commenters stated that it was 
not necessary to require that volume balance reports and attest engagements be submitted by all parties who redesignate certified NTDF to MVNRLM diesel fuel, and that EPA should only require reports from those parties who redesignated a net positive volume of certified NTDF to MVNRLM diesel fuel (i.e., incurred an RVO). We agree with 
these comments and are finalizing provisions to require parties that only incur an RVO through redesignation of certified NTDF to MVNRLM diesel fuel to submit volume balance reports and meet the required attest engagements. Obligated parties that would otherwise have an attest engagement performed (e.g., because they produced gasoline or 
diesel fuel, exported renewable fuels, etc.) would now have the attest auditor perform the additional attest engagement procedures for the obligated party. We believe that the types of reports and records attest auditors review for obligated parties annual 
attest engagements would already include much of the information we are requiring and would therefore represent a minimal increase in burden for these obligated parties. Parties that redesignate certified NTDF to MVNRLM diesel fuel during a compliance period but did not incur an RVO (because they redesignated an equivalent or greater volume of MVNRLM diesel fuel to non- transportation fuel during the compliance period) are required to submit a short report stating that they redesignated certified NTDF to MVNRLM diesel fuel, but did not incur an RVO. We are also not finalizing the proposed requirement for quarterly reports, since compliance will be on an annual basis and can be demonstrated through annual reports. 
Lastly, implementation of these new 
provisions will be delayed until January 1, 2021, to allow time for updates to product codes and tracking software used by distillate distributors. Some 
commenters suggested that this would be helpful for them to avoid implementing the new regulations in the middle of a compliance period, and we agree with these commenters. 
B. Pathway Petition Conditions 
We are clarifying our authority to 
enforce conditions created by 
requirements included in an approval document for a facility-specific pathway petition submitted under 40 CFR 80.1416. Since December 2010, we have approved over 100 facility-specific pathway petitions. To qualify for the generation of RINs under an approved pathway petition, the fuel produced under that pathway must also meet the conditions and applicable regulatory provisions specified in EPA’s petition approval document and the other definitional and regulatory requirements for renewable fuel specified in the CAA and EPA implementing regulations, including for RIN generation, registration, reporting, and recordkeeping. Common conditions include, but are not limited to, compliance monitoring plans detailing how parties will accurately and reliably measure and record the energy and material inputs and outputs required to ensure fuels are produced consistent with the specifications evaluated in the lifecycle analysis, process flow diagrams showing the energy used for feedstock, fuel, and co-product operations, and certifications signed by responsible corporate officers (RCOs). 
We have authority to bring an 
enforcement action of these conditions 
under 40 CFR 80.1460(a), which prohibits producing or importing a renewable fuel without complying with the RIN generation and assignment requirements. The RFS regulations provide that RINs may only be generated if the fuel qualifies for a D code pursuant to 40 CFR 80.1426(f) or an approved petition submitted under 40 CFR 80.1416.
202If any of the 
conditions required by an approval document for a pathway petition are not met, then the fuel does not qualify for a D code per the terms of the approval, and RINs may not be generated. These conditions are also enforceable under 40 CFR 80.1460(b)(2), which prohibits creating a RIN that is invalid; a RIN is invalid if it was improperly generated.
203As stated above, a RIN is 
improperly generated if the fuel representing the RIN does not qualify for a D code, which is the case if a fuel producer does not follow all of the required conditions in the pathway petition approval document. 
We are adding a provision at 40 CFR 
80.1426(a)(1)(iii) to clarify that renewable fuel that qualifies for a D code pursuant to an approved petition submitted under 40 CFR 80.1416 must be produced in compliance with all conditions set forth in the petition approval document (in addition to the applicable statutory requirements and requirements of subpart M). We are also adding a prohibited act at 40 CFR 80.1460(b)(7) for generating a RIN for fuel that fails to meet all the conditions set forth in a petition approval document for a pathway petition submitted under 40 CFR 80.1416 in order to provide more clarity regarding our ability to bring enforcement actions for failure to meet such conditions. 
C. Esterification Pretreatment Pathway 
We are revising rows F and H of Table 
1 to 40 CFR 80.1426 by changing the 
existing approved production process ‘‘Trans-Esterification’’ to be ‘‘Transesterification with or without esterification pretreatment.’’ We are finalizing these revisions to rows F and H without modifying the feedstocks listed in those rows, as these changes do not make any additional feedstocks eligible beyond those already listed in rows F and H. Table 1 to 40 CFR 80.1426 includes pathways for the production of biodiesel using specified feedstocks and the production process transesterification.
204 
Transesterification is the most 
commonly used method to produce biodiesel and involves reacting triglycerides with methanol, typically under the presence of a base catalyst.
205 
While the main component of oils, fats, and grease feedstocks are typically triglycerides, other components, such as free fatty acids (FFAs), can also exist. Removal or conversion of the FFAs is important where the traditional base- catalyzed transesterification production process is used; if they are not removed or converted prior to this process, FFAs will react with base catalysts to produce soaps that inhibit the transesterification reaction. 
One of the most widely used methods 
for treating biodiesel feedstocks with a higher FFA content is acid catalysis. Acid catalysis typically uses a strong 
VerDate Sep<11>2014 20:53 Feb 05, 2020 Jkt 250001 PO 00000 Frm 00043 Fmt 4701 Sfmt 4700 E:\FR\FM\06FER2.SGM 06FER2lotter on DSKBCFDHB2PROD with RULES27058 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations 
206Section 2.4.7.3.3 of the Regulatory Impact 
Analysis for the March 2010 final rule describes the 
material inputs evaluated for biodiesel production. For conversion of yellow grease to biodiesel, sulfuric acid accounted for 4.7 percent of the material inputs on a mass basis (0.02 kg per gallon of biodiesel). 
207In 2012, we issued a direct final rule and a 
parallel proposed rule (see 77 FR 700 and 77 FR 462, respectively; January 5, 2012) that would have determined that, among other regulatory changes, biodiesel produced from esterification met the GHG reduction requirements. Because we received adverse comment, we withdrew the direct final rule in its entirety (see 77 FR 13009, March 5, 2012). In the 2013 final rule based on the parallel proposal (78 FR 14190, March 5, 2013), we decided not to finalize a determination at that time on biodiesel produced from esterification and noted that we would instead make a final determination at a later time. 
208See 83 FR 37735 (August 2, 2018). 
209See 78 FR 14190 (March 5, 2013). 210For the other reasons discussed in the 
sorghum oil rule preamble, see 83 FR 37737–39 
(August 2, 2018). 
211See 82 FR 61205 (December 27, 2017). 
212See 83 FR 37738 (August 2, 2018). 
213See Table III.4 of the sorghum oil rule 
preamble (83 FR 37743, August 2, 2018). acid, such as sulfuric acid, to catalyze 
the esterification of the FFAs prior to the transesterification of the triglycerides as a pre-treatment step. Acid esterification can be applied to feedstocks with FFA contents above 5 percent to produce biodiesel. Because the transesterification of triglycerides is slow under acid catalysis, a technique commonly used to overcome the reaction rate issue is to first convert the FFAs through an acid esterification (also known as an acid ‘‘pretreatment’’ step), and then follow-up with the traditional base-catalyzed transesterification of triglycerides. 
Under the RFS2 final rule, biodiesel 
from biogenic waste oils/fats/greases qualifies for D-codes 4 or 5 using a transesterification process. This conclusion was based on the analysis of yellow grease as a feedstock, where there was an acid pretreatment of the FFAs contained in the feedstock. In fact, one of the material inputs assumed in the modeling for the final RFS2 rule yellow grease pathway was sulfuric acid, which is the catalyst commonly used for acid esterification.
206As we 
had not stipulated transesterification with esterification pretreatment as a qualified production process in rows F and H to Table 1 to 40 CFR 80.1426, we are revising these entries to include ‘‘transesterification with or without esterification pre-treatment’’ as a production process requirement so that RINs may be generated for biodiesel produced by the esterification pretreatment, as well as for the biodiesel produced through transesterification.
207 
In the July 29 proposal, we also 
proposed to add a standalone esterification pathway to rows F and H to Table 1 to 40 CFR 80.1426, which would allow parties who have processing units that can take feedstocks listed in rows F and H of Table 1 to 40 CFR 80.1426 that have high-FFA content and separate the FFAs and triglycerides for chemical processing in separate standalone esterification and transesterification units to generate RINs for the biodiesel produced. However, we are not at this time finalizing the proposed standalone esterification pathway. It remains under consideration and may be finalized in a future action. 
D. Distillers Corn Oil and Distillers 
Sorghum Oil Pathways 
We are adding distillers corn oil and 
commingled distillers corn oil and sorghum oil as feedstocks to row I of Table 1 to 40 CFR 80.1426. While the lifecycle GHG emissions associated with using a very similar feedstock— distillers sorghum oil—as part of this pathway were evaluated in the grain sorghum oil pathway final rule (‘‘sorghum oil rule’’),
208these two 
feedstocks were not added to row I as part of that rulemaking. This section discusses the addition of distillers corn oil and commingled distillers corn oil and sorghum oil as feedstocks to row I and presents the lifecycle GHG emissions associated with these pathways. We also explain why the most likely effect of adding these pathways will be to reduce the number of petitions submitted pursuant to 40 CFR 80.1416. 
The March 2010 RFS2 rule included 
pathways for biodiesel and renewable 
diesel produced from non-food grade corn oil. The March 2013 Pathways I rule added pathways for heating oil and jet fuel from non-food grade corn oil in rows F and H of Table 1 to 40 CFR 80.1426, and added pathways for naphtha and LPG from Camelina sativa oil in row I.
209The sorghum oil rule 
amended the RFS regulations to add a new definition of distillers sorghum oil and to replace existing references to non-food grade corn oil with the newly defined term ‘‘distillers corn oil.’’ That rule also added a number of pathways to rows F and H of Table 1 to 40 CFR 80.1426 for biodiesel, renewable diesel, jet fuel, and heating oil produced from distillers sorghum oil and commingled distillers sorghum and corn oil. Pathways for naphtha and LPG produced from distillers sorghum oil via a hydrotreating process were also added to row I of Table 1 to 40 CFR 80.1426. 
Commingled distillers corn oil and 
sorghum oil was added as a feedstock to rows F and H of Table 1 to 40 CFR 80.1426 because distillers sorghum oil is often co-produced with distillers corn oil at ethanol plants using a combination of grain sorghum and corn as feedstocks for ethanol production. Due to the recovery process of the oils from the distillers grains and solubles 
(DGS), where the ethanol plant is using a feedstock that combines grain sorghum and corn, it is not possible to physically separate the distillers sorghum and corn oils into two streams, nor is it possible to account for the volume of sorghum oil or corn oil in this mixture. For these and other reasons,
210 
after concluding that distillers sorghum oil satisfies the 50 percent GHG reduction threshold required for the advanced biofuel and biomass-based diesel, we added both distillers sorghum oil and ‘‘commingled distillers corn oil and sorghum oil’’ to rows F and H of Table 1 to 40 CFR 80.1426 in the sorghum oil rule. However, unlike rows F and H, row I did not include a pathway using ‘‘non-food grade corn oil’’ prior to that final rule, nor did we propose to add ‘‘distillers corn oil’’ to that row in the December 2017 sorghum oil proposed rule.
211Thus, in the 
absence of an assessment of lifecycle emissions showing that distillers corn oil also meets the GHG reduction threshold required for the pathways therein, in the sorghum oil rule we decided ‘‘it would be premature for EPA to add either distillers corn oil or commingled distillers corn and sorghum oil as feedstocks in row I.’’
212Currently, 
in order to generate D-code 5 RINs for naphtha and/or LPG produced from distillers corn oil and/or commingled distillers corn and sorghum oil, a fuel producer would first need to petition EPA pursuant to 40 CFR 80.1416, have EPA review and approve their requested pathway, and then submit and have EPA accept the registration for the new pathway. Adding these feedstocks to row I eliminates the need for these petitions. 
Table IX.D–1 shows the lifecycle GHG 
emissions associated with renewable diesel, jet fuel, naphtha, and LPG produced from distillers sorghum oil. These results are based on the analysis completed for the sorghum oil rule.
213 
The lifecycle GHG emissions associated with the statutory baseline fuels, 2005 average diesel and gasoline, are shown for comparison. Based on the distillers sorghum oil results, as explained below we have concluded that naphtha and LPG produced from distillers corn oil and commingled distillers corn and sorghum oil also satisfy the 50 percent lifecycle GHG reduction requirement at CAA section 211(o)(1)(B), relative to the

214See Table III.2 (Full-Oil and Reduced-Oil 
Sorghum Distillers Grains with Solubles 
Displacement Ratios) of the sorghum oil rule (83 FR 37741, August 2, 2018) and accompanying footnote 
number 36, which lists the sources for the data in that table. 215See Table 4 of ‘‘Grain Sorghum Oil Pathway 
Petition,’’ Docket Item No. EPA–HQ–OAR–2017– 
0655–0005. 
216The source of the difference is the amount of 
corn needed to replace one pound of full-oil versus reduced-oiled DDGS in beef cattle diets. In our analysis for the sorghum oil rule, we assumed, based on the best available data provided by NSP, USDA, and commenters, that reduced-oil DDGS are replaced at a lower rate (1.173 lbs corn per lbs DDGS) than full-oil DDGS (1.196 lbs corn per lbs DDGS). Increasing the rate of oil extraction produces less de-oiled DDGS and requires corn replacement at the lower rate of 1.173. Thus, all else equal, higher rates of oil extraction result in lower GHG emissions per pound of oil extracted. It is possible this effect would disappear if we had higher resolution data on corn displacement ratios for DDGS with different oil contents, but such data are currently not available. 217In this rulemaking, we did not reexamine our 
well-settled policy of exporter RVOs, which generally require exporters to retire RINs for biofuels they export. We established this policy when we promulgated the regulations implementing the RFS1 and RFS2 programs in 2007 and 2010. See 72 FR 23936 (May 1, 2007); 75 FR 14724 (March 26, 2010). We did not reexamine this issue in this rulemaking, and comments on it are beyond the scope of the rulemaking. We are not making any substantive changes to the relevant provisions, particularly those at 40 CFR 80.1430(a) or (b). Consistent with our long-standing policy, exporters of renewable fuel must continue to acquire sufficient RINs to comply with all applicable RVOs. statutory petroleum baseline, to be 
eligible for advanced biofuel RINs.

Although the lifecycle GHG analysis 
for the sorghum oil rule focused on 
distillers sorghum oil, we believe it is also applicable to distillers corn oil and commingled distillers corn oil and sorghum oil for purposes of determining whether these satisfy the 50 percent GHG reduction requirement. For the sorghum oil rule, we estimated the livestock sector impacts associated with distillers sorghum oil based on a set of assumptions about the type of feed that would need to backfill for the reduction in mass of de-oiled DGS as compared to full-oil DGS. For that analysis we calculated a substitution rate for how much corn would be needed to backfill in livestock feed for every pound of grain sorghum oil diverted to biofuel production, by livestock type. The amounts of corn needed to replace each pound of extracted sorghum oil were largely based on studies that evaluated the nutritional values of regular and reduced-oil distillers grains produced as a co-product of corn starch ethanol.
214 
Given that the underlying data for our distillers sorghum oil assessment was largely based on studies conducted on corn ethanol co-products, we believe it is appropriate to apply the same results to similar pathways using distillers corn oil feedstock. Based on the similarities between the two products and how they are produced (i.e., co-produced at 
ethanol plants), we are also assuming that the lifecycle GHG emission for distillers corn oil and distillers sorghum oil are the same for the other lifecycle stages evaluated (e.g., feedstock 
production, fuel production). 
One difference between distillers corn 
oil and sorghum oil is the rate of oil 
recovered per pound of corn versus grain sorghum processed. The distillers sorghum oil petition submitted by the National Sorghum Producers reported that 0.67 pounds of distillers sorghum oil are recovered per bushel of grain sorghum processed to ethanol, whereas 0.84 pounds of distillers corn oil is extracted per bushel of corn.
215 
Adjusting for this difference results in slightly lower livestock sector GHG emissions associated with naphtha and LPG produced from distillers corn oil.
216Based on this adjustment the 
results in Table IX.D–1 change from a 63 percent GHG reduction for naphtha and LPG produced from distillers sorghum oil to a 64 percent reduction for naphtha and LPG production from distillers corn oil. We have therefore concluded that these pathways satisfy the 50 percent GHG reduction requirement to qualify as advanced biofuel under the RFS program and are adding ‘‘distillers corn oil’’ and ‘‘commingled distillers corn oil and sorghum oil’’ as feedstocks in row I to Table 1 to 40 CFR 80.1426. 
E. Clarification of the Definition of 
Renewable Fuel Exporter and Associated Provisions 
We are finalizing our proposed 
clarification of the definition of ‘‘exporter of renewable fuel.’’ These changes are meant to ensure appropriate flexibility for market participants to meet export obligations and to ensure RINs are properly retired, as well to as to clarify exporter obligations for parties who transfer renewable fuel between the 48 states or Hawaii and an approved opt-in area (i.e., Alaska or the U.S. 
territories were any of them to opt-in). 
The RFS regulations require an 
exporter of renewable fuel to acquire sufficient RINs to comply with all applicable RVOs incurred from the volumes of the renewable fuel exported.
217We previously defined 
‘‘exporter of renewable fuel’’ in 40 CFR 80.1401 as: ‘‘(1) A person that transfers any renewable fuel from a location within the contiguous 48 states or Hawaii to a location outside the contiguous 48 states and Hawaii; and (2) A person that transfers any renewable fuel from a location in the contiguous 48 states or Hawaii to Alaska or a United

21875 FR 14865 (March 26, 2010). 
219See, e.g., 15 CFR 772.1 (defining exporter as 
‘‘[t]he person in the United States who has the 
authority of a principal party in interest to determine and control the sending of items out of the United States’’). We also considered and rejected other alternatives, which we discuss further in the RTC document in the docket for this action. 220Routed export transaction is the term used to 
describe an export transaction in which an FPPI 
directs the movement of goods out of the U.S. and authorizes a U.S. agent to file certain information required by the FTR. 221CAA section 211(o)(2)(A)(i); see also CAA 
section 301(a). 
222See 40 CFR 80.1460(c). 
223To clarify this point, we have revised the 
regulatory text from the proposed ‘‘a transaction’’ to 
‘‘any transaction’’ in this final rulemaking. States territory, unless that state or 
territory has received an approval from 
the Administrator to opt in to the renewable fuel program pursuant to § 80.1443.’’
218 
We are revising these regulations for 
two key reasons. First, during implementation of the RFS program, we have observed contract structuring practices that may have eroded compliance assurance. Notably, we have observed instances of export transactions in which parties have sold renewable fuel for export to entities purporting to accept RIN retirement obligations that were then not fulfilled by the buyer. These instances demonstrate that the RFS program could benefit from regulatory changes designed to ensure that exporter obligations are fulfilled. Therefore, we are revising the definition to resolve any potential ambiguity and clarify which parties may and may not be liable for exporter obligations in order to ensure exporter obligations are fulfilled. 
Second, the previous definition could 
have been construed to include parties who transfer renewable fuel from the contiguous 48 states and Hawaii, to an area (either Alaska or a U.S. territory) that has received an approval to opt-in to the RFS program. We did not intend to impose a RIN retirement obligation on these parties. We are therefore clarifying how exporter obligations apply to renewable fuel transferred between the 48 states and Hawaii, and opt-in areas. 
To achieve these goals when we 
developed the proposal, we initially considered whether to amend the RFS program regulations consistent with the Foreign Trade Regulations (FTR) and other federal export-related regulations, such as United States Principal Party in Interest (USPPI) and Foreign Principal Party in Interest (FPPI).
219While there 
were some commenters that suggested adopting those terms, we chose not to do so for the following reasons. The FTR and other export-related obligations in other federal programs use a traditional definition of ‘‘export’’ where exported goods leave the U.S. The RFS program addresses obligations incurred through the transfer of renewable fuel from areas covered by the program to both domestic and foreign areas not covered by the program. For instance, the transport of goods from Oregon to 
Alaska would not qualify as export under most federal export regulations, but the transport of biofuel from Oregon, a covered area, to Alaska, a non-covered area (unless Alaska chooses to opt in), would qualify as export under the RFS program. In addition, if we merely adopted the FTR approach to allow allocation of exporter obligations among parties to an export transaction, we have concerns that a party that is insolvent or lacking assets in the U.S. could undertake those obligations, and enforcement efforts could become overly resource intensive where the fuel has left the country. For these reasons, we do not believe it would be appropriate to amend the RFS program regulations to define an exporter as the USPPI or the FPPI. 
In reviewing the FTR, we also 
considered the concept of routed export transactions and the associated flexibility for parties to an export transaction to structure that transaction to place some responsibilities with an FPPI.
220We believe that this framework 
is reflective of market custom, practice, and capability to contractually allocate liabilities and indemnities among parties to a commercial transaction. We prefer regulations that accommodate these flexibilities, while also balancing the need to protect RFS program integrity. Specifically, we want to allow parties to an export transaction to allocate RFS program exporter obligations as they see fit among themselves, but we also want to protect against contract structuring that may erode compliance assurance. 
Therefore, we are revising the 
definition of ‘‘exporter of renewable fuel’’ to mean ‘‘all buyers, sellers, and owners of the renewable fuel in any transaction that results in renewable fuel being transferred from a covered location to a destination outside of the covered locations.’’ In conjunction with this revision, we are creating a definition of ‘‘covered location’’ as ‘‘the contiguous 48 states, Hawaii, and any state or territory that has received an approval from the Administrator to opt- in to the RFS program under § 80.1443.’’ As described above, this revised definition permits contract flexibilities frequently employed in export transactions with respect to export obligations under other regulatory programs, such as the FTR. All buyers, sellers, and owners of the renewable fuel in a transaction that results in renewable fuel being transferred from a 
covered location to a destination outside of any covered location may contractually allocate RFS program obligations, indemnities, and pricing as they see fit in light of the regulatory requirements. At the same time, the revised definition provides enhanced compliance assurance so as to maintain a level playing field among would-be exporters and ensures RIN retirement so as to maintain the integrity of that market in accordance with the regulatory requirements. Ultimately, the revised definition contributes to satisfying Congress’s mandate that EPA promulgate regulations that ‘‘ensure’’ the nationally-applicable renewable fuel volumes are met.
221We note, moreover, 
that the existing RFS regulations provide that ‘‘[n]o person shall cause another person to commit an act in violation of any prohibited act under this section.’’
222We believe that this 
prohibition coupled with the revised definitions will deter parties from engaging in sham transactions to evade RIN retirement obligations by transferring ownership of renewable fuels to undercapitalized entities that do not meet their RIN retirement obligations. This includes the specific earlier-described practices we have already observed. The revised definition also clarifies how exporter obligations apply to transfers to and from the contiguous 48 states and Hawaii, and opt-in areas (i.e., Alaska and U.S. 
territories were they to opt-in). Notably, it avoids imposing exporter obligations on biofuels transferred from the 48 states and Hawaii to an opt-in area. 
Under the revised definition, multiple 
parties may meet the definition of an exporter of renewable fuel for the same volume of renewable fuel. In addition, although the definition uses the term ‘‘transaction,’’ in many cases there may be more than one discrete exchange or interaction that results in a volume of renewable fuel being exported. We intend the regulatory term ‘‘transaction’’ to cover all those exchanges and interactions in which the buyers, sellers, and owners know or have reason to know will result in renewable fuel being transferred from a covered location to a destination outside of any covered location.
223For instance, a person 
holding title to renewable fuel in the U.S. may sell renewable fuel to another person (either inside or outside of the

224This example is meant to be a stylized 
illustration of how our regulations could apply. It 
is not meant to exhaustively detail the entities that could meet the definition of exporter of renewable fuel in this type of transaction. To the extent that other parties meet the definition of exporter of renewable fuel, they would also be subject to the exporter provisions. 
225See ‘‘Consolidated List of Reformulated 
Gasoline and Anti-Dumping Questions and 
Answers: July 1, 1994 through November 10, 1997,’’ EPA420–R–03–009, at 256 (July 2003) (discussing a scenario in which two parties would be considered refiners and would be independently responsible for all refinery requirements, which would only need to be met once). 226See ‘‘Consolidated List of Reformulated 
Gasoline and Anti-Dumping Questions and 
Answers: July 1, 1994 through November 10, 1997,’’ EPA420–R–03–009, at 256 (July 2003) (discussing a scenario in which two parties would be considered refiners and would be independently responsible for all refinery requirements, which would only need to be met once). 
227See 81 FR 80828 (November 16, 2016). 
228We are not taking final action at this time on 
several changes from the REGS proposal that were listed in the July 29 proposal (Allowing Production of Biomass-Based Diesel From Separated Food Waste (REGS Section VIII.C), RFS Facility Ownership Changes (REGS Section VIII.H), Public Access to Information (REGS Section VIII.O), and Redesignation of Renewable Fuel on a PTD for Non- Qualifying Uses (REGS Section VIII.R), and certain portions of Other Revisions to the Fuels Program (REGS Section IX), primarily related to test methods). These provisions, along with the other provisions in the REGS proposal that are not being finalized here, remain under consideration and may be finalized in a future action. covered areas) and cause the renewable 
fuel to leave the covered areas. Further, that buyer and seller may have a third party hold title to the renewable fuel during transit out of the covered areas. In this case, the buyer and the seller, both of whom are also owners of the renewable fuel, and the third-party holding company, as another owner of the renewable fuel in the transaction, would be jointly-and-severally liable for complying with the exporter provisions.
224 
However, our revised regulations 
create broad flexibility for parties to assign responsibilities as they see fit among themselves in structuring an export transaction. These parties may contractually allocate RIN retirement, and associated registration, reporting, and attest engagement obligations, to any one of the parties that meets the definition of an exporter of renewable fuel. The party undertaking these requirements would then register as an exporter of renewable fuel as set forth in 40 CFR 80.1450(a). This approach is also consistent with our approach to the term ‘‘refiner,’’ under which multiple parties could be considered the refiner of a batch of fuel. In such instances, we have stated that each party meeting the definition of refiner will be held jointly- and-severally liable for refiner requirements, and we are adopting a consistent approach for exporters of renewable fuel.

and-severally liable for refiner requirements, and we are adopting a consistent approach for exporters of renewable fuel.
226 
EPA does not consider a person to be 
an exporter of renewable fuel if that person does not know and does not have reason to know that the renewable fuel will be exported. For instance, a renewable fuel producer who produces a batch of fuel, generates RINs, and sells the renewable fuel with attached RINs into the fungible fuel distribution system would not be considered an exporter of renewable fuel under the revised definition unless they know or have reason to know that the batch of fuel would be exported. More specifically, the mere fact that a producer introduces renewable fuels into the stream of commerce, coupled with the fact that a significant portion of domestically produced biofuel is exported, does not make the producer an exporter of renewable fuel. 
We are also finalizing minor, non- 
substantive changes throughout the RFS regulations to more consistently use the term ‘‘exporter of renewable fuel’’ rather than the term ‘‘exporter.’’ These clarifying edits reflect that the ‘‘exporter of renewable fuel’’ may be different than the ‘‘exporter’’ under other state and federal regulatory programs. 
F. REGS Rule Provisions 
We are finalizing a number of changes 
to the RFS and fuels programs that were 
previously proposed in the REGS rule,
227and that we listed in the 
preamble to July 29 proposal as candidates for finalization in this action.
228In reaching our final decisions 
on these provisions we considered relevant comments on both the 2016 REGS proposal and the July 29 proposal. As noted in the July 29 proposal, we believe these provisions to be relatively 
straightforward and would reduce the burden of RFS program implementation. Commenters were generally supportive of these provisions and we are largely finalizing them as proposed; changes to the final provisions relative to the 2016 REGS proposal are discussed in detail in the following sections. 
1. Flexibilities for Renewable Fuel 
Blending for Military Use 
We are amending 40 CFR 80.1440 to 
provide new flexibilities for parties that blend renewable fuel to produce fuels for use as transportation fuel, heating oil, or jet fuel under a national security exemption or that sell neat renewable fuel for use in vehicles, engines, and equipment that have a national security exemption for emissions certification. Specifically, these parties will be able to delegate to an upstream party the RIN- related responsibilities (i.e., RIN 
separation, reporting, recordkeeping, and attest engagement requirements) associated with the renewable fuel. These parties could include the U.S. Military itself, or contractors working for the U.S. Military. The RFS program has a provision that allows blenders that handle and blend small volumes of renewable fuel per year (less than 250,000 gallons per year) to delegate RIN-related responsibilities to an upstream party. We have received a 
number of inquiries from parties that have wished to provide renewable fuel, either neat or blended into transportation fuel, for use by the U.S. Military as part of Department of Defense (DOD) renewable military initiatives. One obstacle to this use of renewable fuel by the DOD is that, unlike other EPA fuels programs, there were no exemptions related to national security uses in the RFS regulatory program. 
We believe that it is appropriate to 
allow DOD or its contractors to delegate RFS RIN responsibilities to upstream parties; doing so removes a potential obstacle to the use of renewable fuels by DOD and will promote use of renewable fuel by the military. Therefore, we are finalizing similar upstream delegation provisions for neat and blended renewable fuels supplied to DOD under a national security exemption as those already in place for small renewable fuel blenders. 
2. Heating Oil Used for Cooling 
We are expanding the definition of 
heating oil in 40 CFR 80.1401 to include 
fuels that differ from those meeting the current definition only because they are used to cool, rather than heat, interior spaces of homes or buildings. The first

229See 40 CFR 80.1450(b)(1)(vii)(B). 230See 40 CFR 80.1454(d)(4) and (j). sentence of the definition of heating oil 
thus now reads: ‘‘A fuel oil that is used to heat or cool interior spaces of homes or buildings to control ambient climate for human comfort.’’ We are also making minor modifications to the registration, reporting, PTD, and recordkeeping requirements for renewable heating oil to correspond with this change. We had received questions related to the use of renewable heating oil in equipment that cools interior spaces and believe that displacing the use of petroleum based fuel oil with renewable heating oil for cooling is consistent with CAA section 211(o)’s provision for home heating oil to be treated as additional renewable fuel and should be allowed. 
3. Separated Food Waste Plans 
We are amending the RFS registration 
procedures for separated food waste 
plans at 40 CFR 80.1450(b)(1)(vii)(B) and the recordkeeping requirements for separated food waste at 40 CFR 80.1454(j). We are also adding requirements for renewable fuel produced from biogenic waste oils/fats/ greases at 40 CFR 80.1450(b)(1)(vii)(B) and 80.1454(d)(4) and (j). 
The RFS regulations promulgated in 
the RFS2 rulemaking required that separated food waste plans include: ‘‘(1) The location of any municipal waste facility or other facility from which the waste stream consisting solely of separated food waste is collected; and (2) A plan documenting how the waste will be collected, how the cellulosic and non-cellulosic portions of the waste will be quantified, and for ongoing verification that such waste consists only of food waste (and incidental other components such as paper and plastics) that is kept separate since generation from other waste materials.’’
229In 
addition to the initial submission of separated food waste plans during RFS registration, we also required that renewable fuel producers using separated food waste feedstock update the registration information whenever there was a change to the plan, including to the location(s) of establishments from which the separated food waste is collected, and in some cases the newly updated plan must have been reviewed by a third- party engineer in accordance with EPA registration procedures. We have received numerous company updates for production facilities with separated food waste plans, and some parties noted that the requirement to identify and update suppliers of feedstocks through a plan was overly burdensome. Recognizing that business 
relationships for recovery of food wastes 
evolve and that a renewable fuel producer may elect over time to purchase feedstocks from different or multiple parties, we are removing the requirement to provide the location of every facility from which separated food waste feedstock is collected as part of the information required for registration. Removing this registration requirement alleviates the need for numerous company registration updates as a facility’s feedstock supplier list evolves, as well as makes it easier for EPA to review renewable fuel producers’ separated food waste plans in a timely manner. However, the recordkeeping section of the regulations requires renewable fuel producers to keep documents associated with feedstock purchases and transfers that identify where the feedstocks were produced; these documents must be sufficient to verify that the feedstocks meet the definition of renewable biomass.
230 
Thus, renewable fuel producers will still be required to maintain records that demonstrate that they used a qualifying feedstock to produce renewable fuels for the generation of RINs pursuant to the recordkeeping requirements at 40 CFR 80.1454(d)(4) and (j). We are also adding a provision at 40 CFR 80.1454(j)(1)(ii) that will require renewable fuel producers to maintain records demonstrating the location of any establishment from which the waste stream is collected. Since many renewable fuel producers receive wastes used as feedstocks from an aggregator, we interpret the term ‘‘location’’ to mean the physical address that the aggregator obtained the wastes used as feedstocks from, not the physical or company address of the aggregator. 
In addition to removing the 
registration requirement to provide the locations of establishments from which separated food waste is collected, we are also modifying the registration regulations to require that separated food waste plans identify the type(s) of separated food waste(s) to be used and the type(s) of establishment(s) the waste will be collected from. For instance, CAA section 211(o) identifies ‘‘recycled cooking and trap grease’’ as a type of separated food waste. Examples of types of establishments could be restaurants, slaughterhouses, or specific food production plants (the kind of food production should be provided). We believe this information is necessary for EPA to determine at registration whether a renewable fuel producer can make fuel from its proposed feedstock under currently approved separated 
food waste pathways. Without this information, we would not know what the specific feedstock is (e.g., tallow, 
yellow grease, etc.) or whether it qualifies as a separated food waste. 
We are also requiring under 40 CFR 
80.1450(b)(1)(vii)(B) that producers of renewable fuels made from biogenic waste oils/fats/greases that are not separated food waste submit a plan at registration with the same requirements as the plan for producers of renewable fuels made from separated food waste. We are henceforth referring to such plans as ‘‘waste oils/fats/greases feedstock plans.’’ There is significant overlap between the two categories of feedstock, with a considerable quantity of biogenic waste oils/fats/greases qualifying as renewable biomass as a result of its additional qualification as separated food waste. For these reasons, as a matter of practice we have required parties intending to use biogenic waste oils/fats/greases as a renewable fuel feedstock to submit separated food waste plans at registration. In addition to helping EPA determine if the feedstock in question meets renewable biomass requirements, we have found that the plans help us assess whether the feedstocks specified by a prospective producer qualify as biogenic waste oils/fats/greases. This assessment is made on a case-by-case basis. This amendment conforms the regulations to EPA’s current practice. A party fully describing its feedstock in a separated food waste plan will not be required to submit an additional waste oils/fats/ greases plan. Since most, if not all, producers of renewable fuel from biogenic waste oils/fats/greases have submitted a separated food waste plan at registration, we do not believe that this revision will add much, if any, burden to existing registered facilities. Those few registered producers using biogenic waste oils/fats/greases that have not previously submitted a separated food waste plan at registration or in a subsequent registration update will be required to do so as part of their next periodic registration update. 
In addition to adding the registration 
requirement for a waste oils/fats/greases feedstock plan to 40 CFR 80.1540(b)(1)(vii)(B), we are also adding 
the same recordkeeping requirements for biogenic oils/fats/greases as for separated food waste at 40 CFR 80.1454(d)(4) and (j), and providing further clarity that the locations from which separated food waste or biogenic oils/fats/greases was sourced is a recordkeeping requirement.

notification to correct the deficiencies identified or explain why there is no need for corrective action. See 40 CFR 80.1450(h)(2)(i). 
232In the REGS proposal, we proposed to use the 
term ‘‘company, third-party auditor, or third-party engineer’’ in the registration deactivation provisions; however, we are now using the term ‘‘party’’ to refer more generally to any person that may be required to register with EPA. 4. Additional Registration Deactivation 
Justifications 
We are adding additional 
circumstances in which EPA may deactivate the registration of any party required to register under 40 CFR 80.1450. These amendments will help parties better understand when EPA intends to restrict a party’s participation in the RFS program as well as the procedures that will be used in such circumstances. 
In July 2014, we finalized 
requirements that described circumstances under which EPA may deactivate a company registration and an administrative process to initiate deactivation that provides companies an opportunity to respond to and/or submit the required information in a timely manner.
231Since finalizing these 
requirements, we have identified a number of other cases in which it is appropriate to deactivate the registration of a company. In addition, we believe the provisions should be extended to cover deactivation of registrations for any party required to register with EPA under 40 CFR 80.1450 (e.g., third-party 
auditors).
232Specifically, we are 
amending 40 CFR 80.1450(h)(1) to provide that EPA may deactivate registrations of a party for the following reasons in addition to those previously listed: 
•The party fails to comply with the 
registration requirements of 40 CFR 80.1450. 
•The party fails to submit any 
required report within thirty days of the required submission date. 
•The party fails to pay a penalty or 
to perform any requirements under the terms of a court order, administrative order, consent decree, or administrative settlement agreement between the party and EPA. 
•The party submits false or 
incomplete information. 
•The party denies EPA access or 
prevents EPA from completing authorized activities under CAA section 114 despite our presenting a warrant or court order. This includes a failure to provide reasonable assistance. 
•The party fails to keep or provide 
EPA with the records required in 40 CFR part 80, subpart M. •The party otherwise circumvents 
the intent of the CAA or 40 CFR part 80, subpart M. 
These deactivation circumstances are 
consistent with cases where EPA may deny or revoke a certificate of conformity under 40 CFR 1051.255(c) and 86.442–78 for engines and vehicles manufactured in or imported into the U.S. In addition, we are finalizing requirements that state that in instances of willful violation of an applicable requirement or those in which public health, interest, or safety requires otherwise, EPA may also deactivate the registration of a party without providing notice to the party prior to deactivation and will send written notification to the RCO describing the reasons for the deactivation. Parties can still submit new registrations after appropriate actions are taken by the party to remedy the deficiency. 
5. New RIN Retirement Section 
We are creating a new section in the 
RFS regulations for RIN retirements. 
The regulations have specific sections that address when and how parties may generate and separate RINs. However, the cases where parties must retire RINs were identified in various sections throughout the regulations. The new section of the RFS regulations for RIN retirements, 40 CFR 80.1434, simply organizes these current sections into one place and will provide beneficial clarification by enumerating the specific instances in which a party must retire RINs in a new section of the regulations and by making those retirements consistent with how parties administratively retire RINs in EMTS. We are aware of some confusion for some parties causing those parties to improperly retire RINs or fail to retire RINs when they have a responsibility to do so under the regulations. Improper retirements can lead to a time- consuming remediation process, both for EPA and responsible parties. This new section organizes these requirements into one location in the regulations to make the circumstances under which RINs must be retired simpler to locate and understand. The section also includes new regulatory language for cases requiring RIN retirement that are identified in EMTS, but may not be clear in the regulations, given their current organization (e.g., in 
the case of contaminated or spoiled fuel). Our intent is not to add additional burden on parties that must retire RINs under the RFS program, but rather to make the regulations consistent with how parties already retire RINs in EMTS and help reduce potential confusion regarding the situations in which parties 
must retire RINs. 
We are finalizing the elements of the 
new RIN retirement section at 40 CFR 80.1434 as proposed, with the exception of the provisions for expired RINs and redesignated renewable fuel, which we are not finalizing because we have determined they are not necessary for program implementation at this time. 
6. New Pathway for Co-Processing 
Biomass With Petroleum To Produce Co-Processed Cellulosic Diesel, Jet Fuel, and Heating Oil 
We are creating a new definition of 
‘‘co-processed cellulosic diesel’’ to refer to biodiesel or non-ester renewable diesel fuels that meet the definition for cellulosic biofuel but not the definition of biomass-based diesel. We are also finalizing new pathways that allow co- processed cellulosic diesel, jet fuel, and heating oil that are derived from co- processing biomass with petroleum to qualify as cellulosic biofuel and generate cellulosic (D-code 3) RINs, provided certain production process requirements are satisfied. Fuels that meet the cellulosic diesel definition will continue to be able to generate D7 RINs, while fuels that meet the co-processed cellulosic diesel definition but not the cellulosic diesel definition due to co- processing with petroleum will be able to generate D3 RINs. Fuels produced through co-processing with petroleum will also be required to meet, among other requirements, the requirements of 40 CFR 80.1426(f)(4) to determine the number of RINs that can be generated. 
While pathways existed for renewable 
gasoline and gasoline blendstock (row M in Table 1 to 40 CFR 80.1426) and naphtha (row N in Table 1 to 40 CFR 80.1426) produced from cellulosic biomass that is co-processed with petroleum, there was no pathway for diesel, jet fuel, or heating oil produced in this manner. The pathway for 
cellulosic diesel, jet fuel, and heating oil (Pathway L in Table 1 to 40 CFR 80.1426) excludes processes that co- process renewable biomass and petroleum. To qualify as cellulosic diesel, a fuel must meet the requirements for both cellulosic biofuel and biomass-based diesel. The definition of biomass-based diesel explicitly excludes renewable fuels that are derived from co-processing biomass with petroleum, and therefore a process that produced diesel, jet fuel, or heating oil by co-processing renewable biomass with petroleum could not qualify as biomass-based diesel or cellulosic diesel under Pathway L in Table 1 to 40 CFR 80.1426. However, cellulosic biofuels other than cellulosic diesel are not

233Another part of the 2016 REGS proposal, 
which we are not finalizing here, would have 
amended the definition of ‘‘cellulosic diesel’’ so that it no longer required that such fuel meet the definition of biomass-based diesel.

236Id. 
237See for example discussion of hydrotreated 
camelina oil in that March 2013 Pathways I rule at 78 FR 14198. 
238For example, for the 2010 RFS2 rule EPA 
estimated slightly lower refining emissions (9.2 gCO2e/MJ) for 2005 average U.S. gasoline than for 2005 U.S. average diesel (9.0 gCO2e/MJ). Other studies have found an even larger reduction for refining diesel as compared to gasoline. See for example: Cooney, G., et al. (2017). ‘‘Updating the U.S. Life Cycle GHG Petroleum Baseline to 2014 with Projections to 2040 Using Open-Source Engineering-Based Models.’’ Environmental Science 
& Technology 51(2): 977–987. While this may be different when biogenic feedstocks are used, it is reasonable to conclude that any differences would not be large enough to disqualify the fuel from satisfying the 60 percent GHG reduction threshold. 
23981 FR 80927 (November 16, 2016). 
240This new definition for ‘‘co-processed 
cellulosic diesel’’ is essentially the same as the revised definition of ‘‘cellulosic diesel’’ that we proposed in the 2016 REGS proposal; creating a new term rather than revising an existing definition allows us to avoid legacy issues within our IT system. prohibited from being derived from 
biomass co-processed with petroleum. 
In the 2016 REGS proposed rule, we 
proposed to add a new row U to Table 1 to 40 CFR 80.1426 that would have allowed for cellulosic diesel, jet fuel and heating oil produced from any of the feedstocks listed in row L via any process that co-processes renewable biomass with petroleum and converts cellulosic biomass to fuel to qualify for cellulosic biofuel (D-code 3) RINs.
233 
While most commenters supported this proposed addition, several commenters disagreed. The dissenting commenters stated that EPA had not conducted a sufficient lifecycle GHG analysis to support the pathways proposed for row U. After reviewing these comments, we have decided to finalize a narrower set of pathways for co-processed cellulosic diesel. Instead of adding a new row U to Table 1 to 40 CFR 80.1426, we are instead adding ‘‘Co-Processed Cellulosic Diesel, Jet Fuel, and Heating Oil’’ as fuel types in row M. Thus, as we had proposed, we are finalizing new pathways for co-processed cellulosic diesel, jet fuel, and heating oil, but for a narrower set of feedstocks and production process requirements. Compared to the proposed row U, row M contains the same feedstocks except that it does not include any energy grasses (i.e., switchgrass, miscanthus, 
energy cane, Arundo donax, Pennisetum purpureum), and row M contains a more narrowly defined set of production process requirements. Note that the energy grass feedstocks are the only ones in the proposed row U that include significant indirect land use change emissions based on EPA’s lifecycle GHG analysis of switchgrass for the March 2010 RFS2 rule. Finalizing this narrower set of pathways addresses the commenters concerns about insufficient analysis because approval of these pathways is supported by the extensive analyses that we conducted for a previous rule. 
The pathways in row M were 
approved in the March 2013 Pathways I rule and may include fuels produced through the co-processing renewable biomass and petroleum.
234The analysis 
supporting that rulemaking found that the pathways evaluated for corn stover feedstock reduced lifecycle GHG emissions by at least 65 to 129 percent compared to the statutory petroleum baseline, and the results for corn stover were extended to the other feedstocks listed in row M. We are now extending those results to cover co-processed cellulosic diesel, jet fuel, and heating oil produced from the same feedstocks and processes listed in row M. The analysis for the March 2013 Pathways I rule did not explicitly evaluate co-processing but the upgrading processes were modeled as using the same types of equipment and processes as petroleum refining.
235 
Indeed, the analysis was largely based on a report that evaluated processes that co-produce gasoline and diesel products.
236The most likely processes 
in row M to include co-processing are the ones that have upgrading as the final step, as upgrading is a common part of petroleum refining. Our analysis for the March 2013 Pathways I rule estimated a 67 percent GHG reduction compared to conventional gasoline for renewable gasoline and renewable gasoline blendstock produced from corn stover through catalytic pyrolysis and upgrading. Producing cellulosic diesel instead of renewable gasoline through this same pathway would produce similar results satisfying the 60 percent GHG reduction threshold. When energy allocation is used for GHG accounting, which is the approach we have used for co-produced RIN generating fuels,
237co- 
produced gasoline and diesel products will have the same, or nearly the same GHG emissions per unit of energy. Studies looking at petroleum refining have also found that upgrading to diesel fuel is less GHG-intensive than upgrading to gasoline.
238Based on these 
assessments we conclude that the lifecycle GHG emissions associated with the new pathways being added to row M satisfy the statutory 60 percent GHG reduction requirement to qualify as cellulosic biofuel. In summary, the analyses conducted for the March 2013 Pathways I rule support the addition of ‘‘co-processed cellulosic diesel, jet fuel and heating oil’’ as feedstocks to row M of Table 1 to 40 CFR 80.1426, and commenters did not provide sufficient data or information to support a different conclusion. 
The 2016 REGS proposal also 
included a revised definition for ‘‘cellulosic diesel’’ and a new term, ‘‘cellulosic biomass-based diesel.’’
239 
These proposed revisions would have, among other things, removed the requirement for ‘‘cellulosic diesel’’ to meet the definitions of both cellulosic biofuel and biomass-based diesel. The new term, ‘‘cellulosic biomass-based diesel,’’ would have effectively replaced ‘‘cellulosic diesel’’ and would have required that the renewable fuel meet both definitions. However, after considering the implementation issues associated with revising an existing definition within EPA’s IT systems (e.g., changing existing registrations), we have decided not to finalize either of the definitional changes proposed in the 2016 REGS rule. Instead, we are accomplishing the same result by leaving the definition of ‘‘cellulosic diesel’’ as-is and are adding a new term, ‘‘co-processed cellulosic diesel,’’ which is, among other things, a renewable fuel that meets the definitions of cellulosic biofuel and either biodiesel or non-ester renewable diesel.
240Importantly, co- 
processed cellulosic diesel can be produced as a result of co-processing cellulosic feedstocks with petroleum and is eligible for D-code 3 RINs, but not D-code 7 RINs. It is thus ‘‘co-processed cellulosic diesel, jet fuel, and heating oil’’ that we are adding to row M of Table 1 to 40 CFR 80.14626. 
7. Other Revisions to the Fuels Program 
a. Testing Revisions 
We are removing the requirement for 
periodic resubmitting of non-voluntary 
consensus standard body (non-VCSB) test methods that have not been approved by VCSBs in 40 CFR 80.585(d)(4). Currently, non-VCSB test methods are required to resubmit accuracy and precision qualification information every 5 years if the non- VCSB test method has not been approved by a VCSB organization. At this time, VCSBs, such as ASTM, have yet to qualify any non-VCSB test methods for measuring the sulfur content in diesel, gasoline, or butane. Moreover, we require minimal statistical quality control requirements on every

241See 40 CFR 80.584. 
242See, e.g., 40 CFR 80.47(j)(2). 243See 79 FR 23414 (April 28, 2014).

diesel sulfur accuracy and precision requirements
241to ensure proper test 
method instrumentation use is as intended in practice. We are, therefore, amending the regulatory requirement by eliminating the provision for non-VCSB test methods to re-submit accuracy and precision qualification information every 5 years. 
We are also removing the sunset date 
for designated primary test methods in 40 CFR 80.47. EPA fuels regulations exempted those designated primary test 
methods that were in use prior to October 28, 2013, from meeting the accuracy and precision qualification requirements.
242We provided this 
sunset exemption date in the Tier 3 final rule because we were confident that test facilities were utilizing designated primary test methods prior to this date. However, since the statistical quality control (SQC) requirements at 40 CFR 80.47 are intended to ensure proper utilization of designated primary test methods in practice, we are removing this sunset exemption date. This action exempts all designated primary test methods from the accuracy and precision requirements of 40 CFR 80.47. 
b. Oxygenate Added Downstream in 
Tier 3 
After the Tier 3 final rule was 
published,
243we received several 
questions concerning the language at 40 CFR 80.1603(d) about accounting for downstream oxygenate blending in refiners’ and importers’ average annual sulfur calculations. Specifically, some refiners asked whether 40 CFR 80.1603(d) is consistent with the related reformulated gasoline (RFG) provisions for downstream oxygenate blending in 40 CFR 80.69. Currently, refiners may certify RFG after the addition of oxygenate to the reformulated blendstock for oxygenate blending (RBOB) sample at the refinery lab (creating a so-called ‘‘hand blend’’), as 
allowed in 40 CFR 80.69(a). The Tier 3 regulations at 40 CFR 80.1603(d) require that refiners and importers account for downstream oxygenate blending to any gasoline or blendstock for oxygenate blending (BOB) by volume weighting the sulfur content of the gasoline or BOB with the sulfur content of the added oxygenate. Under the Tier 3 regulations, refiners and importers may either rely upon test results of batches of oxygenate supplied by the producer of the oxygenate or use an assumed value of 5.00 ppm added at 10 volume percent ethanol concentration if actual sulfur results are not available. These refiners and importers suggested that the regulatory language at 40 CFR 80.1603(d) may be interpreted to continue to allow the use of hand- blended RBOB samples for determining oxygenate sulfur content added downstream by arguing that the language at 40 CFR 80.1603(d) only applied to conventional gasoline and conventional blendstock for oxygenate blending (CBOB). 
We intended for the downstream 
oxygenate blending regulations at 40 CFR 80.1603(d) to apply to all gasoline and BOBs, not just conventional gasoline and CBOB. In the preamble to the Tier 3 final rule, we explained that 
the ‘‘final rule requires that in determining their compliance with today’s sulfur standards, refiners and importers must either use the actual sulfur content of the denatured fuel ethanol (DFE) established through testing of the DFE actually blended or assume a 5 ppm sulfur content for the DFE added downstream. To prevent potential bias, a refiner or importer must choose to use only one method during each annual compliance period.’’
244 
The regulations at 40 CFR 80.101(d)(4) set forth the criteria that a refiner must meet to include downstream ethanol in their conventional gasoline compliance calculations, and 40 CFR 80.69 sets forth the criteria a refiner must meet to include downstream ethanol in their RFG or RBOB compliance calculations. If a refiner satisfies these criteria, 40 CFR 80.1603(d) sets forth the mechanism for accounting for downstream ethanol in annual compliance calculations for all gasoline and BOBs. This section of the regulations was designed to ensure that all refiners calculate their annual average sulfur levels by including the ethanol that is actually added to their gasoline or BOBs, or to use the default value of 5 ppm sulfur content. This would alleviate the need for refiners to use hand blends prepared with ethanol that has less sulfur than is actually blended with the refiner’s gasoline or BOB for their compliance calculations. 
Although we believe that 40 CFR 
80.1603(d) clearly applies to all gasoline and BOBs, not just RFG or RBOB, we are making minor amendments to ensure that these requirements are as clear as possible to the regulated community. We are also making minor amendments to the Tier 3 sulfur reporting requirements at 40 CFR 80.1652 to better accommodate the inclusion of downstream oxygenate blending in annual average sulfur compliance demonstrations. These added requirements will help align the reported batch information with the annual average compliance report and is necessary to ensure that refiners met both the per-gallon and annual average sulfur standards. 
c. Technical Corrections and 
Clarifications 
We are making numerous technical 
corrections to EPA’s fuels programs. These amendments are being made to correct inaccuracies and oversights in the current regulations. These changes are described in Table IX.F.7–2 below.

Many interested parties participated 
in the rulemaking process that 
culminates with this final rule. This process provided opportunity for submitting written public comments following the proposal that we published on July 29, 2019 (84 FR 36762) and the supplemental notice of proposed rulemaking published on October 28, 2019. We also held public hearings on July 31, 2019 and October 30, 2019, at which many parties provided both verbal and written testimony. All comments received, both verbal and written, are available in Docket ID No. EPA–HQ–OAR–2019– 0136 and we considered these comments in developing the final rule. Public comments and EPA responses are discussed throughout this preamble and in the accompanying RTC document, which is available in the docket for this action. 
XI. Statutory and Executive Order 
Reviews 
A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review 
This action is a significant regulatory 
action that was submitted to the Office of Management and Budget (OMB) for review. Any changes made in response to OMB recommendations have been documented in the docket. EPA prepared an analysis of illustrative costs associated with the 2020 percentage standards. This analysis is presented in Section V. 
B. Executive Order 13771: Reducing 
Regulations and Controlling Regulatory Costs 
This action is considered an 
Executive Order 13771 regulatory action. Details on the estimated costs of the 2020 percentage standards can be found in EPA’s analysis of the illustrative costs. This analysis is presented in Section V. 
C. Paperwork Reduction Act (PRA) 
The existing Information Collection 
Request (ICR) covering the RFS program 
is entitled ‘‘Recordkeeping and Reporting for the Renewable Fuel Standard Program,’’ EPA ICR No. 2546.01, OMB Control Number 2060– 0725; expires August 31, 2022. The existing RFS ICR covers registration, recordkeeping, and reporting requirements currently in 40 CFR part 80, subpart M. The changes affecting RVO calculations will not change the recordkeeping and reporting burdens vis-a`-vis the existing collection. However, certain of the amendments in 
this action will result in an additional burden. The information collection activities related to the amendments to the RFS regulations in this rule have 
been submitted for approval to the Office of Management and Budget (OMB) under the PRA. You can find a copy of the ICR in the docket for this rule, identified by EPA ICR Number 2595.02, OMB Control Number 2060– NEW, and it is briefly summarized here. The parties for whom we anticipate an increase in burden are generally described as RIN generators (specifically, those who are producers of renewable fuel) due the amendments related to pathways, and those who are generally described as obligated parties (specifically, those who are refiners and importers) due to the provisions for certified NTDF. The supporting statement clearly indicates the amendments and includes detailed tables with regulatory burden laid out by type of party, regulatory citation, description of information to be collected, estimated burden in hours and dollars, and reporting form or format. Certain amendments in this action are related to non-RFS fuels programs, but these amendments are mostly technical corrections (e.g., address corrections) and do not impose any additional recordkeeping and reporting burden. 
The Following Summarizes the Burden 
Respondents/affected entities: The 
respondents to this information 
collection are RIN generators and obligated parties under the RFS program, and fall into the following general industry categories: Petroleum refineries, ethyl alcohol manufacturers, other basic organic chemical manufacturing, chemical and allied products merchant wholesalers, petroleum bulk stations and terminals, petroleum and petroleum products merchant wholesalers, gasoline service stations, and marine service stations. 
Respondent’s obligation to respond: 
Mandatory. 
Estimated number of respondents: 
6,042. 
Total number of responses: 357,512. 
Frequency of response: Annually and 
occasionally. 
Total estimated burden: 32,548 hours 
(per year). Burden is defined at 5 CFR 
1320.3(b). 
Total estimated cost: $3,511,813 (per 
year). 
An agency may not conduct or 
sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves this ICR, EPA will announce that approval in the Federal Register and publish a technical 
amendment to 40 CFR part 9 to display the OMB control number for the approved information collection activities contained in this final rule. 
D. Regulatory Flexibility Act (RFA) 
I certify that this action will not have 
a significant economic impact on a 
substantial number of small entities under the RFA. In making this determination, the impact of concern is any significant adverse economic impact on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden, or otherwise has a positive economic effect on the small entities subject to the rule. 
With respect to the amendments to 
the RFS regulations and other fuels programs, this action makes relatively minor corrections and modifications to those regulations, and we do not anticipate that there will be any significant adverse economic impact on directly regulated small entities. 
The small entities directly regulated 
by the annual percentage standards associated with the RFS volumes are small refiners, which are defined at 13 CFR 121.201. With respect to the 2020 percentage standards, we have evaluated the impacts on small entities from two perspectives: As if the standards were a standalone action or if they are a part of the overall impacts of the RFS program as a whole. 
When evaluating the standards as if 
they were a standalone action separate and apart from the original rulemaking that established the RFS2 program, the standards could be viewed as increasing the cellulosic biofuel, advanced biofuel, and total renewable fuel volume requirements by 170 million gallons between 2019 and 2020. To evaluate the impacts of the volume requirements on small entities relative to 2019, we have conducted a screening analysis
245to 
assess whether we should make a finding that this action will not have a significant economic impact on a substantial number of small entities. Currently available information shows that the impact on small entities from implementation of this rule will not be significant. We have reviewed and

246For a further discussion of the ability of 
obligated parties to recover the cost of RINs see 
‘‘Denial of Petitions for Rulemaking to Change the RFS Point of Obligation,’’ EPA–420–R–17–008, November 2017. 
24775 FR 14670 (March 26, 2010). 248Moreover, we note that the 2021 BBD volume 
only establishes the maximum BBD volume for that 
year and may be adjusted in subsequent actions. This volume does not directly regulate any entity. We intend to translate this volume, subject to any appropriate adjustments, into a percentage standard in the 2021 annual rulemaking. We also acknowledge that today’s action does impose the 2020 BBD percentage standard. As we explain in Section VI and in the preamble to the 2019 final rule, this percentage standard is not practically binding, as we expect obligated parties to rely on BBD RINs, in excess of this standard, to satisfy the 2020 advanced biofuel standard. Thus, any impact on directly regulated entities from the 2020 BBD percentage standard is subsumed into the impact of the 2020 advanced biofuel standard. As we explain in this section and the screening memo, we find that the 2020 advanced biofuel standard will not 
have a significant economic impact on a substantial number of small entities under the RFA. 
249See CAA section 211(o)(9)(B). 
250Information about the number of SREs granted 
can be found at: https://www.epa.gov/fuels- assessed the available information, 
which shows that obligated parties, including small entities, are generally able to recover the cost of acquiring the RINs necessary for compliance with the RFS standards through higher sales prices of the petroleum products they sell than would be expected in the absence of the RFS program.
246This is 
true whether they acquire RINs by purchasing renewable fuels with attached RINs or purchase separated RINs. The costs of the RFS program are thus generally being passed on to consumers in the highly competitive marketplace. Even if we were to assume that the cost of acquiring RINs was not recovered by obligated parties, and we used the maximum values of the costs discussed in Section V and the gasoline and diesel fuel volume projections and wholesale prices from the October 2019 version of EIA’s Short Term Energy Outlook, along with current wholesale biofuel prices, a cost-to-sales ratio test shows that the costs to small entities of the RFS standards are far less than 1 percent of the value of their sales. 
While the screening analysis 
described above supports a certification that this rule will not have a significant economic impact on small refiners, we continue to believe that it is more appropriate to consider the standards as a part of our ongoing implementation of the overall RFS program. When considered this way, the impacts of the RFS program as a whole on small entities were addressed in the RFS2 final rule, which was the rule that implemented the entire program as required by EISA 2007.
247As such, the 
Small Business Regulatory Enforcement Fairness Act (SBREFA) panel process that took place prior to the 2010 rule was also for the entire RFS program and looked at impacts on small refiners through 2022. 
For the SBREFA process for the RFS2 
final rule, we conducted outreach, fact- finding, and analysis of the potential impacts of the program on small refiners, which are all described in the Final Regulatory Flexibility Analysis, located in the rulemaking docket (EPA– HQ–OAR–2005–0161). This analysis looked at impacts to all refiners, including small refiners, through the year 2022 and found that the program would not have a significant economic impact on a substantial number of small entities, and that this impact was expected to decrease over time, even as the standards increased. For gasoline and/or diesel small refiners subject to the standards, the analysis included a cost-to-sales ratio test, a ratio of the estimated annualized compliance costs to the value of sales per company. From this test, we estimated that all directly regulated small entities would have compliance costs that are less than one percent of their sales over the life of the program (75 FR 14862, March 26, 2010). 
We have determined that this final 
rule will not impose any additional requirements on small entities beyond those already analyzed, since the impacts of this rule are not greater or fundamentally different than those already considered in the analysis for the RFS2 final rule assuming full implementation of the RFS program. This rule increases the 2020 cellulosic biofuel, advanced biofuel, and total renewable fuel volume requirements by 170 million gallons relative to the 2019 volume requirements, but those volumes remain significantly below the statutory volume targets analyzed in the RFS2 final rule. Compared to the burden that would be imposed under the volumes that we assessed in the screening analysis for the RFS2 final rule (i.e., the volumes specified in the 
Clean Air Act), the volume requirements in this rule reduce burden on small entities. Regarding the BBD standard, we are maintaining the volume requirement for 2021 at the same level as the 2020 volume requirement we finalized in the 2019 final rule.
248While 
this volume is an increase over the statutory minimum value of 1 billion gallons, the BBD standard is a nested standard within the advanced biofuel category, which we are significantly reducing from the statutory volume targets. As discussed in Section VI, the BBD volume requirement is below what is anticipated to be produced and used to satisfy the advanced biofuel requirement. The net result of the standards being finalized in this action is a reduction in burden as compared to 
implementation of the statutory volume targets assumed in the RFS2 final rule analysis. 
While the rule will not have a 
significant economic impact on a substantial number of small entities, there are compliance flexibilities in the program that can help to reduce impacts on small entities. These flexibilities include being able to comply through RIN trading rather than renewable fuel blending, 20 percent RIN rollover allowance (up to 20 percent of an obligated party’s RVO can be met using previous-year RINs), and deficit carry- forward (the ability to carry over a deficit from a given year into the following year, provided that the deficit is satisfied together with the next year’s RVO). In the RFS2 final rule, we discussed other potential small entity flexibilities that had been suggested by the SBREFA panel or through comments, but we did not adopt them, in part because we had serious concerns regarding our authority to do so. 
Additionally, we realize that there 
may be cases in which a small entity may be in a difficult financial situation and the level of assistance afforded by the program flexibilities is insufficient. For such circumstances, the program provides hardship relief provisions for small entities (small refiners), as well as for small refineries.
249As required by 
the statute, the RFS regulations include a hardship relief provision (at 40 CFR 80.1441(e)(2)) that allows for a small refinery to petition for an extension of its small refinery exemption at any time based on a showing that the refinery is experiencing a ‘‘disproportionate economic hardship.’’ EPA regulations provide similar relief to small refiners that are not eligible for small refinery relief (see 40 CFR 80.1442(h)). We have currently identified a total of 9 small refiners that own 11 refineries subject to the RFS program, all of which are also small refineries. 
We evaluate these petitions on a case- 
by-case basis and may approve such petitions if it finds that a disproportionate economic hardship exists. In evaluating such petitions, we consult with the U.S. Department of Energy and consider the findings of DOE’s 2011 Small Refinery Study and other economic factors. To date, EPA has adjudicated petitions for exemption from 37 small refineries for the 2018 RFS standards (10 of which are owned by a small refiner).
250We have not yet

registration-reporting-and-compliance-help/rfs- 
small-refinery-exemptions. adjudicated any small refinery 
exemption petitions for the 2019 or 2020 RFS standards. 
In sum, this final rule will not change 
the compliance flexibilities currently offered to small entities under the RFS program (including the small refinery hardship provisions we continue to implement) and available information shows that the impact on small entities from implementation of this rule will not be significant viewed either from the perspective of it being a standalone action or a part of the overall RFS program. We have therefore concluded that this action will not have any significant adverse economic impact on directly regulated small entities. 
E. Unfunded Mandates Reform Act 
(UMRA) 
This action does not contain an 
unfunded mandate of $100 million or more as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. This action implements mandates specifically and explicitly set forth in CAA section 211(o) and we believe that this action represents the least costly, most cost-effective approach to achieve the statutory requirements. 
F. 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. 
G. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This action does not have tribal 
implications as specified in Executive Order 13175. This action 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 will be affected only to the extent they produce, purchase, or use regulated fuels. Thus, Executive Order 13175 does not apply to this action. 
H. Executive Order 13045: Protection of 
Children From Environmental Health Risks and Safety Risks 
EPA interprets Executive Order 13045 
as applying only to those regulatory actions that concern environmental health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of ‘‘covered regulatory action’’ in section 2–202 of the Executive Order. This action is not subject to Executive Order 13045 because it implements specific standards established by Congress in statutes (CAA section 211(o)) and does not concern an environmental health risk or safety risk. 
I. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This action is not a ‘‘significant 
energy action’’ because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. This action establishes the required renewable fuel content of the transportation fuel supply for 2020, consistent with the CAA and waiver authorities provided therein. The RFS program and this rule are designed to achieve positive effects on the nation’s transportation fuel supply, by increasing energy independence and security and lowering lifecycle GHG emissions of transportation fuel. 
J. National Technology Transfer and 
Advancement Act (NTTAA) 
This rulemaking does not involve 
technical standards. 
K. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
EPA believes that this action does not 
have disproportionately high and adverse human health or environmental effects on minority populations, low income populations, and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). This regulatory action does not affect the level of protection provided to human health or the environment by applicable air quality standards. This action does not relax the control measures on sources regulated by the RFS and other fuels regulations. 
L. Congressional Review Act (CRA) 
This action is subject to the CRA, and 
the EPA will submit a rule report to 
each House of the Congress and to the Comptroller General of the United States. This action is a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). 
XII. Statutory Authority 
Statutory authority for this action 
comes from sections 114, 203–05, 208, 
211, and 301 of the Clean Air Act, 42 U.S.C. 7414, 7522–24, 7542, 7545, and 7601.

(b) Precision and accuracy criteria for 
approval for the absolute fuel parameter 
of gasoline sulfur—(1) Precision. 
Beginning January 1, 2016, for motor vehicle gasoline, gasoline blendstock, and gasoline fuel additives subject to the gasoline sulfur standard at §§ 80.195 and 80.1603, the maximum allowable standard deviation computed from the results of a minimum of 20 tests made over 20 days (tests may be arranged into no fewer than five batches of four or fewer tests each, with only one such batch allowed per day over the minimum of 20 days) on samples using good laboratory practices taken from a single homogeneous commercially available gasoline must be less than or equal to 1.5 times the repeatability ‘‘r’’ divided by 2.77, where ‘‘r’’ equals the ASTM repeatability of ASTM D7039 (Example: A 10 ppm sulfur gasoline sample: Maximum allowable standard 
deviation of 20 tests≤1.5*(1.73ppm/ 2.77) = 0.94 ppm). The 20 results must be a series of tests with a sequential record of analysis and no omissions. A laboratory facility may exclude a given sample or test result only if the exclusion is for a valid reason under good laboratory practices and it maintains records regarding the sample and test results and the reason for excluding them. 
(2) Accuracy. Beginning January 1, 
2016, for motor vehicle gasoline, gasoline blendstock, and gasoline fuel additives subject to the gasoline sulfur standard at §§ 80.195 and 80.1603: 
(i) The arithmetic average of a 
continuous series of at least 10 tests performed using good laboratory practices on a commercially available gravimetric sulfur standard in the range of 1–10 ppm shall not differ from the accepted reference value (ARV) of the standard by more than 0.47 ppm sulfur,

0.75*(1.5*r/2.77), where ‘‘r’’ is the repeatability for ARV of the commercially available gravimetric sulfur standard (Example: 0.75*(1.5*1.15ppm/2.77) = 0.47 ppm); 
(ii) The arithmetic average of a 
continuous series of at least 10 tests performed using good laboratory practices on a commercially available gravimetric sulfur standard in the range of 10–20 ppm shall not differ from the ARV of the standard by more than 0.94 ppm sulfur, where the accuracy criteria is 0.75*(1.5*r/2.77), where ‘‘r’’ is the repeatability for ARV of the commercially available gravimetric sulfur standard (Example: 0.75*(1.5*2.30ppm/2.77) = 0.94 ppm); and

the event that contamination or spoliation of any volume of renewable fuel is reported, the owner of the renewable fuel must notify any holder or holders of the attached RINs and retire a number of gallon-RINs corresponding to the volume of contaminated or spoiled renewable fuel multiplied by its equivalence value. 
(i) If the equivalence value for the 
contaminated or spoiled volume may be determined pursuant to § 80.1415 based on its composition, then the appropriate equivalence value shall be used. 
(ii) If the equivalence value for a 
contaminated or spoiled volume of renewable fuel cannot be determined, the equivalence value shall be 1.0. 
(iii) If the owner of a volume of 
renewable fuel that is contaminated or spoiled and reported establishes that no RINs were generated to represent the volume, then no gallon-RINs shall be retired. 
(7) Delayed RIN generation. In the 
event that a party generated a delayed RIN as described in § 80.1426(g)(1) through (4), parties must retire RINs as described in accordance with § 80.1426(g)(5) and (6). 
(8) Invalid RIN. In the case that a RIN 
is invalid as described in § 80.1431(a), the RIN will be considered invalid and must be retired as described in § 80.1431(b). 
(9) Potentially invalid RINs. In the 
case that a RIN is identified as a PIR under § 80.1474(b)(1), the PIRs or replacement RINs must be retired as described in § 80.1474(b)(2) through (5). 
(10) Replacement. As required by 
§ 80.1431(b) or § 80.1474, any party that must replace an invalid RIN or PIR that was used for compliance must retire valid RINs to replace the invalid RINs originally used for any RVO. 
(11) Other. Any other instance 
identified by EPA. (b) In the case that retirement of a RIN 
is necessary, the following provisions apply: 
(1) Any party affected by such 
retirement must keep copies and adjust its records, reports, and compliance calculations in which the retired RIN was used. 
(2) The retired RIN must be reported 
in the applicable reports under § 80.1451.
