The Environmental Protection Agency Misses the Deadline for Setting Renewable Fuel Standards for 2021

December 17, 2020

Under Section 211(o) of the Clean Air Act, each November, the Environmental Protection Agency (“EPA”) is required to set standards for the percentage of renewable fuel that must be included in gasoline and diesel produced or imported into the United States the following year. The EPA―which was required to issue a catch-up rule in 2015 setting the standards for 2014, 2015, and 2016―has been generally successful in meeting (or nearly so) the statutory deadline during the Trump administration. However, the COVID-19 pandemic and the associated decrease in travel/demand for fuel has complicated the EPA’s decision-making process, and this year the deadline was missed. The new priorities of the incoming Biden administration will likely further delay the issuance of the new standards.

Renewable Fuel Standards

Section 211(o) of the Clean Air Act, as amended, requires that transportation fuel sold or introduced into commerce in the US (except in noncontiguous states or territories) contain a specified volume of renewable fuel on an annual average basis. The renewable fuel standards are expressed as volume percentages, known as Renewable Volume Obligations, and are used by obligated parties (refiners and importers) to determine their compliance obligations. The EPA sets the applicable percentages for cellulosic biofuel, biomass-based diesel, advanced biofuel (which includes cellulosic biofuel and biomass-based diesel), and total renewable fuel (which includes advanced biofuel, as well as conventionally produced ethanol) such that if each obligated party meets the percentages, and if the EPA’s projections of gasoline and diesel use for the year are accurate, then the amount of all renewable fuel and of cellulosic biofuel, biomass-based diesel, and advanced biofuel used will meet the required volumes on a nationwide basis. Thus, to set the renewable fuel percentage standards, the EPA must first specify the required volumes for each fuel type.

On December 19, 2019, the EPA finalized volume requirements under the RFS program for 2020 for cellulosic biofuel, advanced biofuel, and total renewable fuel, and for 2021 for biomass-based diesel. 85 Fed. Reg. 7016 (Feb. 6, 2020). In May 2020, the EPA delivered to the Office of Management and Budget (“OMB”) a proposed rule setting volume requirements for 2021; however, the proposal remains under OMB review and has not been released for public comment. The annual volume standards for 2010-2020 (and the final biomass-based diesel volume for 2021) are set forth in the table below; all volumes are in billions of gallons, except cellulosic biofuel, which is in millions of gallons, and all are ethanol-equivalent, except biomass-based diesel, which is actual.

Cellulosic Biofuel

The Clean Air Act requires that the EPA base the standard for cellulosic biofuel on the volume of cellulosic biofuel projected to be produced during the relevant year. The volume standards for cellulosic biofuel have always been much lower than those set by the Clean Air Act, which, for 2020, is 10.5 billion gallons, rather than the 590 million gallons set by the EPA. Notably, on January 25, 2013, the D.C. Circuit vacated the EPA’s 2012 standard for cellulosic biofuel, finding that the EPA’s projection of the volume of cellulosic biofuel to be produced in 2012 was not neutral, but was biased in favor of promoting growth in the cellulosic biofuel industry. American Petroleum Institute v. EPA, No. 12-1139 (D.C. Cir. Jan. 25, 2013). Following the court’s ruling, the EPA removed the 2011 and 2012 requirement for cellulosic biofuel.

When the EPA sets the applicable volume for cellulosic biofuel below the volume specified in the Clean Air Act, the EPA is required to offer waiver credits that can be purchased in lieu of acquiring cellulosic biofuel Renewable Identification Numbers (“RINs”), which are used for compliance with the renewable fuel standards. For the 2019 compliance period, the price per waiver credit is $1.77. 85 Fed. Reg. at 7025, n. 36.

Biomass-Based Diesel

The Clean Air Act specifies the volumes of biomass-based diesel through 2012; after that, the EPA is required to determine the extent to which a portion of the advanced biofuel volume should be set aside exclusively for biomass-based diesel. Starting in 2013, the EPA has set the biomass-based diesel above the one billion gallon floor specified by the Clean Air Act, including volumes of 2.43 billion gallons for 2021 and 2022. As explained by the EPA, “the advanced biofuel requirement is driving the production and use of biodiesel and renewable diesel volumes over and above volumes required through the separate [biomass-based diesel] standard,” a trend the EPA expects will continue. Id. at 7019.

Advanced Biofuel and Total Renewable Fuel

The Clean Air Act authorizes the EPA to set volumes for advanced biodiesel and total renewable fuel that are below those specified in the statute, which, for 2021, is 30 billion gallons. For 2020, the EPA reduced the volume requirements and associated applicable percentage standards for advanced biofuels and total renewable fuel to account for the reduction in cellulosic ethanol in order to maintain the implied statutory volumes for non-cellulosic advanced and conventional renewable fuel. Id. at 7019-20.

The EPA also has general authority under Section 211(o)(7)(A) to wave the statutory volumes based on economic or environmental harm or inadequate domestic fuel supply. For 2020, the EPA declined to use this authority, finding that the statutory criteria were not met.1


The EPA can grant limited compliance exemptions to small refineries based on economic hardship and has issued approximately 80 such waivers. In addition, on October 21, 2020, a group of oil-state senators submitted a letter to EPA Administrator Andrew Wheeler, asking him to waive the 2021 standards to prevent increased use of renewable fuels and to “account for the unprecedented collapse in demand for gasoline, diesel, and jet fuel.”2 The ethanol industry has criticized such waivers as reducing demand for ethanol.

In January 2020, the Tenth Circuit vacated exemptions granted by the EPA to three refineries, finding that the EPA can only grant extensions of existing exemptions (going back to 2010) and cannot grant new exemptions. Renewable Fuels Assoc. v. HollyFrontier Cheyenne Refining LLC, No. 18-9533 (10th Cir. Jan. 24, 2020). The subject refiners have sought review by the Supreme Court, arguing that the Tenth Circuit’s decision would “forever preclude[] from receiving an exemption” a small refinery that does not experience disproportionate economic hardship for a single year; the EPA has not appealed the decision.

In November 2020, the Fourth Circuit vacated the EPA’s decision denying a small refinery economic hardship exemption, finding that the EPA had treated similar refineries differently. Ergon-West Virginia, Inc. v. EPA, No. 19-2152 (4th Cir. Nov. 17, 2020). The Fourth Circuit did not address the question of new exemptions versus continuing exemptions at issue in Renewable Fuels Assoc.In September 2020, the EPA rejected 54 requests by refineries for hardship exemptions for compliance years 2011-2018. In November 2020, EPA Administrator Andrew Wheeler said the agency has 35 more pending waiver requests for 2019 and 2020, but will not make a decision on those requests until after the Renewable Fuels Assoc. litigation is concluded.


The Biden administration will have to answer several key questions regarding the renewable fuels program, including (i) whether to offset the limited availability of cellulosic ethanol with increased requirements for conventional renewable fuels or to maintain the implied statutory volumes for non-cellulosic advanced and conventional renewable fuel as the Trump administration has done, and (ii) the appropriate scope of small refinery waivers. A potentially lengthy delay in the issuance of 2021 standards will create significant uncertainty for the renewable and conventional fuel sectors. We will provide updates on further developments as they become available.

1 In 2017, the D.C. Circuit vacated the EPA’s use of the general waiver authority based on inadequate domestic supply, finding that the EPA had impermissibly considered demand-side factors in its assessment of inadequate domestic supply, rather than limiting its assessment to supply-side factors. Americans for Clean Energy v. EPA, 864 F.3d 691 (D.C. Cir. 2017).
