40 CFR Part 80 - REGULATION OF FUELS AND FUEL ADDITIVES

In this action, the Environmental Protection Agency (EPA) determines that biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process, meet the lifecycle GHG emissions reduction threshold of 50 percent required for advanced biofuels and biomass-based diesel under the Renewable Fuel Standard (RFS) program. Based on these analyses, EPA is adding these pathways to the list of approved renewable fuel production pathways in the RFS regulations. EPA is also amending the RFS regulations by adding a new definition of “distillers sorghum oil,” and replacing existing references to “non-food grade corn oil” with the newly defined term “distillers corn oil.”

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 proposes 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 2019. 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 proposing volume requirements for cellulosic biofuel, advanced biofuel, and total renewable fuel that are below the statutory volume targets. We are also proposing the applicable volume of biomass-based diesel for 2020.

The Environmental Protection Agency (EPA) is announcing a public hearing to be held in Ypsilanti, MI on July 18, 2018 for the proposed rule “Renewable Fuel Standard Program: Standards for 2019 and Biomass-Based Diesel Volume for 2020.” This proposed rule will be published separately in the Federal Register . The pre-publication version of this proposal can be found at https://www.epa.gov/renewable-fuel-standard-program/regulations-and-volume-standards-under-renewable-fuel-standard. In the separate notice of proposed rulemaking, EPA has proposed amendments to the renewable fuel standard program regulations that would establish annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and renewable fuels that would apply to all gasoline and diesel produced in the U.S. or imported in the year 2019. In addition, the separate proposal includes a proposed biomass-based diesel applicable volume for 2020.

The Environmental Protection Agency (EPA) is proposing to approve a request from Louisiana for EPA to relax the federal Reid Vapor Pressure (RVP) standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year for the Louisiana parishes of East Baton Rouge, West Baton Rouge, Livingston, Ascension, and Iberville (the Baton Rouge area). Specifically, EPA is proposing to amend the regulations to allow the RVP standard for the Baton Rouge area to change from 7.8 pounds per square inch (psi) to 9.0 psi for gasoline. EPA has preliminarily determined that this change to the federal RVP regulation is consistent with the applicable provisions of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action in announcing its approval of the petition by Kentucky to opt-out of the federal reformulated gasoline (RFG) program and remove the requirement to sell federal RFG for Boone, Campbell, and Kenton counties (the Northern Kentucky Area), which are part of the Cincinnati-Hamilton, Ohio-Kentucky-Indiana maintenance area for the 2008 ozone national ambient air quality standard (NAAQS) (Cincinnati-Hamilton, OH-KY-IN Area). EPA has determined that this removal of the federal RFG program for the Northern Kentucky Area is consistent with the applicable provisions of the Clean Air Act (CAA) and EPA's regulations.

In this proposed rule, the Environmental Protection Agency (EPA) is providing an opportunity to comment on an analysis of the lifecycle greenhouse gas (GHG) emissions associated with certain biofuels that are produced from grain sorghum oil extracted at dry mill ethanol plants at any point downstream from sorghum grinding, also known as distiller sorghum oil. EPA seeks comment on its proposed assessment that using distillers sorghum oil as feedstock results in no significant agricultural sector GHG emissions; and that biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process, would meet the lifecycle GHG emissions reduction threshold of 50 percent required for advanced biofuels, and biomass-based diesel under the Renewable Fuel Standard program. Based on these analyses, EPA is proposing to amend the RFS program regulations to define the term “distillers sorghum oil”. We also propose to add to the regulations approved pathways from the production of biodiesel and heating oil from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process.

The Environmental Protection Agency (EPA) is taking final action to approve an April 10, 2017 request from the Louisiana Department of Environmental Quality (LDEQ) to relax the Federal Reid Vapor Pressure (RVP) standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year for the following parishes: Beauregard, Calcasieu, Jefferson, Lafayette, Lafourche, Orleans, Pointe Coupee, St. Bernard, St. Charles, St. James, and St. Mary. Specifically, EPA is approving amendments to the regulations to allow the gasoline RVP standard for these 11 parishes to rise from 7.8 pounds per square inch (psi) to 9.0 psi. EPA has determined that this change to the Federal gasoline RVP volatility regulation is consistent with the applicable provisions of the Clean Air Act (CAA). LDEQ has also requested that EPA relax gasoline volatility requirements for the 5-parish Baton Rouge area, and EPA will address that request in a separate rulemaking in the future.

The Environmental Protection Agency (EPA) is taking final action to approve a request from the state of Tennessee for EPA to relax the Reid Vapor Pressure (RVP) standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year (summertime ozone season) in Shelby County, Tennessee (the Memphis Area). Specifically, EPA is approving amendments to the regulations to allow the gasoline RVP standard for Shelby County to rise from 7.8 pounds per square inch (psi) to 9.0 psi. EPA has determined that this change to the federal RVP regulation is consistent with the applicable provisions of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is providing notice of its denial of several petitions requesting that EPA initiate a rulemaking process to reconsider or change 40 CFR 80.1406, which identifies refiners and importers of gasoline and diesel fuel as the entities responsible for complying with the annual percentage standards adopted under the Renewable Fuel Standard (RFS) program.

This document provides additional data and an opportunity to comment on that data and potential options for reductions in the 2018 biomass-based diesel, advanced biofuel, and total renewable fuel volumes, and/or the 2019 biomass-based diesel volume under the Renewable Fuel Standard (RFS) program. In a July 21, 2017 notice of proposed rulemaking, the EPA proposed certain reductions in the statutory volume targets for advanced biofuel and total renewable fuel for 2018, and requested comment on further reductions based on various considerations. This document presents additional data on production, imports and cost of renewable fuel and several options for how we may consider such data in establishing the final volume requirements using the waiver authorities provided by the statute.

The Environmental Protection Agency (EPA) is proposing to approve a request from Tennessee for EPA to relax the Federal Reid Vapor Pressure (RVP) standard applicable to gasoline introduced into commerce from June 1 to September 15 of each year for Shelby County, Tennessee (Memphis or Area). Specifically, EPA is proposing to amend the regulations to allow the RVP standard for Shelby County to change from 7.8 pounds per square inch (psi) to 9.0 psi for gasoline.

In accordance with the Presidential directive as expressed in the memorandum of January 20, 2017, from the Assistant to the President and Chief of Staff, entitled “Regulatory Freeze Pending Review,” this action temporarily delays until March 21, 2017, the effective date of the regulations listed in the table below. EPA identified 30 regulations that meet those criteria.

On November 22, 2016, the U.S. Environmental Protection Agency (“EPA”) published a Notice of its proposed denial of several petitions requesting that EPA initiate a rulemaking process to reconsider or change its regulations that identify refiners and importers of gasoline and diesel fuel as the entities responsible for complying with the annual percentage standards adopted under the Renewable Fuel Standard (RFS) program. The Notice invited public comment on this proposal by January 23, 2017—60 days after publication of the Notice in the Federal Register . On December 13, 2016, the EPA received a request from the Small Retailers Coalition to extend the comment period by 30 days to allow its members to provide thorough comments and data. In light of the importance of this issue, the EPA is extending the deadline for written comments an additional 30 days to February 22, 2017.

On November 16, 2016, the Environmental Protection Agency (EPA) proposed the Renewables Enhancement and Growth Support (REGS) rule. The proposal specified that the public comment period would end on January 17, 2017, 60 days after publication in the Federal Register . On December 9, 2016, the EPA received a joint request for an extension of the comment period from the following parties: American Soybean Association, Corn Refiners Association, Global Renewable Strategies and Consulting, LLC, Growth Energy, Iowa Biodiesel Board, Iowa Renewable Fuels Association, National Biodiesel Board, National Renderers Association, Renewable Fuels Association, and U.S. Canola Association. The petitioners requested an extension in order to have more time to evaluate the implications of the REGS rule. In light of the large number of revisions proposed in this action, the EPA is extending the deadline for written comments on the proposal by 30 days to February 16, 2017.

This Notice provides an opportunity to comment on new information that pertains to the proposed provisions for ethanol flex fuel contained in the Renewables Enhancement and Growth Support (REGS) rule which was published in the Federal Register on November 16, 2016. The new information is contained in the report titled “Property Analysis of Ethanol—Natural Gasoline—BOB Blends to Make Flex Fuel” that has been placed in the public docket for this action. In the proposed REGS rule, the EPA proposed volatility standards for ethanol flex fuel (EFF) to prevent excessive evaporative emissions that could adversely affect the emissions control systems of flexible fuel vehicles (FFVs) and human health. The EPA proposed a fuel volatility compliance tool for use by regulated entities to demonstrate compliance with the proposed volatility standards for EFF. The new information being made available by this notice indicates that the proposed compliance tool may need to be modified to adequately estimate the volatility of EFF when natural gasoline is used as a blendstock.

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 all motor vehicle gasoline and diesel produced or imported in the year 2017. Relying on statutory authority that is available when projected cellulosic biofuel production volumes are less than the applicable volume specified in the statute, the EPA is setting volume requirements for cellulosic biofuel, advanced biofuel, and total renewable fuel that are below the statutory applicable volumes, but which are nevertheless significantly higher than past requirements. The final rule also establishes the four percentage standards applicable to obligated parties, namely producers and importers of gasoline and diesel, based on the corresponding volume requirements. The final standards are expected to continue driving the market to overcome constraints in renewable fuel distribution infrastructure, which in turn is expected to lead to substantial growth over time in the production and use of renewable fuels. In this action, we are also establishing the applicable volume of biomass-based diesel for 2018.

The Environmental Protection Agency (EPA) is proposing to deny several petitions requesting that EPA initiate a rulemaking process to reconsider or change its regulations that identify refiners and importers of gasoline and diesel fuel as the entities responsible for complying with the annual percentage standards adopted under the Renewable Fuel Standard (RFS) program. EPA is providing an opportunity for the public to comment on the petitions we have received and on our proposed denial of the requests to initiate rulemaking.

In this action, the Environmental Protection Agency (EPA) is proposing to update both its renewable fuels and other fuels regulations to reflect changes in the marketplace and to promote the growing use of both ethanol fuels (conventional and advanced) and non-ethanol advanced and cellulosic biofuels. The EPA is proposing to make several changes to the Renewable Fuel Standard (RFS) program regulations that would align them with recent developments in the marketplace to increase production of cellulosic and other advanced biofuels. There are several companies that have developed renewable fuel production technologies that produce a “biointermediate” at one facility that is then processed into renewable fuel at another facility, and we are proposing regulatory changes to allow fuels produced through such methods to qualify under existing approved renewable fuel production pathways. This action also proposes to update our fuel regulations by defining fuel blends containing 16 to 83 volume percent ethanol as ethanol flex fuel (EFF) and to no longer treat fuel blends containing 16 to 50 volume percent ethanol as gasoline. The EPA is proposing environmentally protective fuel quality specifications for EFF that are consistent with those already in place for gasoline. In this action we are also proposing new pathways for cellulosic biofuel produced from short-rotation trees and for renewable diesel and biodiesel produced from non-cellulosic portions of separated food waste. We are also proposing to add new registration, recordkeeping, and reporting requirements for facilities using carbon capture and storage if we were to approve the use of this technology in future assessments of proposed pathways for producing qualifying renewable fuel. We are also seeking comment on how best to implement and/or revise the RFS regulations pertaining to the generation of RINs for renewable electricity used as transportation fuel. Finally, we are proposing a number of other regulatory changes, clarifications, and technical corrections to the RFS program and other fuels regulations.

The Environmental Protection Agency (EPA) is announcing a public hearing to be held in Chicago, Illinois on December 6, 2016, on its proposal for the “Renewables Enhancement and Growth Support (REGS) Rule.” The public can view the proposal at https://www.epa.gov/renewable-fuel-standard-program/proposed-renewables-enhancement-and-growth-support-regs-rule. Comments submitted at the public hearing will contribute to the REGS Rule proposal that the EPA will publish at a later date in the Federal Register .

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 proposes the annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel that would apply to all motor vehicle gasoline and diesel produced or imported in the year 2017. The EPA is proposing a cellulosic biofuel volume that is below the applicable volume specified in the Act. Relying on statutory waiver authorities, the EPA is also proposing to reduce the applicable volumes of advanced biofuel and total renewable fuel. The proposed standards are expected to continue driving the market to overcome constraints in renewable fuel distribution infrastructure, which in turn is expected to lead to substantial growth over time in the production and use of renewable fuels. In this action, we are also proposing the applicable volume of biomass-based diesel for 2018.

The Environmental Protection Agency (EPA) is announcing a public hearing to be held in Kansas City, Missouri on June 9, 2016 for the proposed rule “Renewable Fuel Standard Program: Standards for 2017 and Biomass-Based Diesel Volume for 2018.” This proposed rule will be published separately in the Federal Register . The pre-publication version of this proposal can be found at https://www.epa.gov/renewable-fuel-standard-program/standards-2017-and-biomass-based-diesel-volume-2018-documents. In the separate notice of proposed rulemaking, EPA has proposed amendments to the renewable fuel standard program regulations that would establish annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and renewable fuels that would apply to all gasoline and diesel produced in the U.S. or imported in the year 2017. In addition, the separate proposal includes a proposed biomass-based diesel applicable volume for 2018.

The Environmental Protection Agency (EPA) is taking final action on technical corrections and clarifications withdrawn from a previous direct final rule that amended provisions from the April 2014 Tier 3 final rulemaking and the July 2014 Quality Assurance Program final rulemaking. The regulatory changes being finalized in this final rule correct errors identified by the commenters and provide more clarity in the regulations to ensure that the regulations properly reflect the requirements established in those rules.

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 all motor vehicle gasoline and diesel produced or imported in the years 2014, 2015, and 2016. The EPA is establishing a cellulosic biofuel volume for all three years that is below the applicable volume specified in the Act, and is also rescinding the cellulosic biofuel standard for 2011. Relying on statutory waiver authorities, the EPA is adjusting the applicable volumes of advanced biofuel and total renewable fuel for all three years. The 2016 standards are expected to spur further progress in overcoming current constraints in renewable fuel distribution infrastructure, which in turn is expected to lead to substantial growth over time in the production and use of renewable fuels. In this action, we are also establishing the applicable volume of biomass-based diesel for 2017. Finally, we are setting the compliance and attest reporting deadlines for the years 2013, 2014, and 2015, as well as finalizing regulatory amendments to clarify the scope of the existing algal biofuel pathway.

In addition, the separate proposal includes a proposed biomass-based diesel applicable volume for 2017.

Because EPA received adverse comment on certain elements of the Tier 3 Amendments direct final rule published on February 19, 2015, we are withdrawing those elements of the direct final rule. EPA intends to consider the comments received and proceed with a new final rule for the withdrawn elements. The remaining elements will go into effect pursuant to the direct final rule.

The Environmental Protection Agency (EPA) is extending the Clean Air Act's (CAA) prohibition against the sale of conventional gasoline in reformulated gasoline (RFG) areas to the southern Maine counties of York, Cumberland, Sagadahoc, Androscoggin, Kennebec, Knox, and Lincoln (hereinafter, the “Southern Maine Counties”). This action is based on a request from the Governor of the State of Maine for areas within the ozone transport region established under the CAA. The CAA does not give the EPA discretion to deny a Governor's request on this matter. The scope of the EPA's discretion is limited to establishing the date that the prohibition commences. Consistent with the Governor's request, the EPA is finalizing as proposed a prohibition commencement date of May 1, 2015 for all refiners, importers, and distributors in the Maine counties referenced in the Governor's request, and June 1, 2015 for all retailers and wholesale purchaser- consumers in those counties. The EPA is also adding in its RFG opt-out rules a provision to reflect that there is a four-year minimum opt-in period for areas that opt into the RFG program on the basis of their location within the ozone transport region. This clarification aligns the federal regulation for RFG opt-out requirements with the CAA.

The Environmental Protection Agency (EPA) is announcing that it will not be finalizing 2014 applicable percentage standards under the Renewable Fuel Standard (RFS) program before the end of 2014. In light of this delay in issuing the 2014 RFS standards, the compliance demonstration deadline for the 2013 RFS standards will take place in 2015. EPA will be making modifications to the EPA-Moderated Transaction System (EMTS) to ensure that Renewable Identification Numbers (RINs) generated in 2012 are valid for demonstrating compliance with the 2013 applicable standards.
