40 CFR 80, Subpart L -

The EPA is announcing two public hearings to be held for the proposed rule “Control of Air Pollution from Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards” (the proposed rule is hereinafter referred to as “Tier 3”), which will be published separately in the Federal Register . The hearings will be held in Philadelphia, PA on April 24, 2013 and in Chicago, IL on April 29, 2013. The comment period for the proposed rulemaking will end on June 13, 2013.

EPA is issuing a final rule identifying additional fuel pathways that EPA has determined meet the biomass-based diesel, advanced biofuel or cellulosic biofuel lifecycle greenhouse gas (GHG) reduction requirements specified in Clean Air Act section 211(o), the Renewable Fuel Standard (RFS) Program, as amended by the Energy Independence and Security Act of 2007 (EISA). This final rule describes EPA's evaluation of biofuels produced from camelina ( Camelina sativa ) oil and energy cane; it also includes an evaluation of renewable gasoline and renewable gasoline blendstocks, and clarifies our definition of renewable diesel. The inclusion of these pathways creates additional opportunity and flexibility for regulated parties to comply with the advanced and cellulosic requirements of EISA and provides the certainty necessary for investments to bring these biofuels into commercial production from these new feedstocks. We are not finalizing at this time determinations on biofuels produced from giant reed ( Arundo donax ) or napier grass ( Pennisetum purpureum ) or biodiesel produced from esterification. We continue to consider the issues concerning these proposals, and will make a final decision on them at a later time.

Under section 211(o) of the Clean Air Act, the Environmental Protection Agency is required to set the renewable fuel standards each November for the following year. In general the standards are designed to ensure that the applicable volumes of renewable fuel specified in the statute are used. However, the statute specifies that EPA is to project the volume of cellulosic biofuel production for the upcoming year and must base the cellulosic biofuel standard on that projected volume if it is less than the applicable volume set forth in the Act. EPA is today proposing a projected cellulosic biofuel volume for 2013 that is below the applicable volume specified in the Act. EPA is proposing that the applicable volumes of advanced biofuel and total renewable fuel would remain at the statutory levels for 2013. Finally, today's action also proposes annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and renewable fuels that would apply to all gasoline and diesel produced or imported in year 2013.

On October 31, 2012 the EPA published a request for comments on a Regulatory Flexibility Act section 610 review titled, Section 610 Review of NPDES Permit Regulation and Effluent Limitations Guidelines Standards for Concentrated Animal Feeding Operations (CAFOs). As initially published in the Federal Register , written comments were to be submitted to the EPA on or before December 31, 2012 (a 60-day public comment period). Since publication, the EPA has received a request for additional time to submit comments. Therefore, the EPA is extending the public comment period for 60 days until March 1, 2013.

EPA is amending the requirements under EPA's diesel sulfur program related to the sulfur content of locomotive and marine (LM) diesel fuel produced by transmix processors and pipeline facilities. These amendments will reinstate the ability of locomotive and marine diesel fuel produced from transmix by transmix processors and pipeline operators to meet a maximum 500 parts per million (ppm) sulfur standard outside of the Northeast Mid-Atlantic Area and Alaska and expand this ability to within the Northeast Mid-Atlantic Area provided that: the fuel is used in older technology locomotive and marine engines that do not require 15 ppm sulfur diesel fuel, and the fuel is kept segregated from other fuel. These amendments will provide significant regulatory relief for transmix processors and pipeline operators to allow the petroleum distribution system to function efficiently while continuing to transition the market to virtually all ultra-low sulfur diesel fuel (ULSD, i.e. 15 ppm sulfur diesel fuel) and the environmental benefits it provides.

EPA is issuing a supplemental rule associated with the Renewable Fuel Standard (RFS) program. This final rule contains a lifecycle GHG analysis for grain sorghum ethanol and a regulatory determination that grain sorghum ethanol qualifies as a renewable fuel under the RFS Program. EPA's analysis indicates that ethanol made from grain sorghum at dry mill facilities that use natural gas for process energy meets the lifecycle greenhouse gas emissions reduction threshold of 20 percent compared to the baseline petroleum fuel it would replace, and therefore qualifies as renewable fuel. It also contains our regulatory determination that grain sorghum ethanol produced at dry mill facilities using specified forms of biogas for both process energy and most electricity production, has lifecycle GHG emission reductions of more than 50 percent compared to the baseline petroleum fuel it would replace, and that such grain sorghum ethanol qualifies as an advanced biofuel under the RFS Program.

EPA published a direct final rule on October 9, 2012 to amend the definition of heating oil in 40 CFR 80.1401 in the Renewable Fuel Standard (“RFS”) program under section 211(o) of the Clean Air Act. The direct final rule also amended requirements under EPA's diesel sulfur program related to the sulfur content of locomotive and marine diesel fuel produced by transmix processors, and the fuel marker requirements for 500 ppm sulfur locomotive and marine (LM) diesel fuel to allow for solvent yellow 124 marker to transition out of the distribution system. Because EPA received adverse comments on the heating oil definition and transmix amendments, we are withdrawing those portions of the direct final rule. Because EPA did not receive adverse comments with respect to the yellow marker amendments, those amendments will become effective as indicated in the direct final rule.

This notice announces that EPA will review three regulatory actions pursuant to section 610 of the Regulatory Flexibility Act. Those three actions are: Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements (Heavy-Duty 610 Review); NESHAP: Reinforced Plastic Composites Production (Plastics 610 Review); and NPDES Permit Regulation and Effluent Limitations Guidelines Standards for CAFOs (CAFO 610 Review). As part of this review, EPA will consider and solicit comments on the following factors: The continued need for the rules; the nature of complaints or comments received concerning the rules; the complexity of the rules; the extent to which the rules overlap, duplicate, or conflict with other Federal, State, or local government rules; and the degree to which the technology, economic conditions or other factors have changed in areas affected by the rules.

Under the Clean Air Act Section 211(o), the Environmental Protection Agency is required to determine the applicable volume of biomass-based diesel to be used in setting annual percentage standards under the renewable fuel standard program for years after 2012. We proposed an applicable volume requirement for 2013 of 1.28 billion gallons on July 1, 2011. In order to sufficiently evaluate the many comments on the proposal from stakeholders as well as to gather additional information to enhance our analysis, we did not finalize this volume requirement in the January 9, 2012, rulemaking setting the 2012 percentage standards. In this action we are finalizing an applicable volume of 1.28 billion gallons of biomass-based diesel for calendar year 2013.
