Proposed 2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and Corporate Average Fuel Economy Standards EPA and NHTSA, on behalf of the Department of Transportation, are issuing this joint proposal to further reduce greenhouse gas emissions and improve fuel economy for light-duty vehicles for model years 2017-2025. This proposal extends the National Program beyond the greenhouse gas and corporate average fuel economy standards set for model years 2012-2016. On May 21, 2010, President Obama issued a Presidential Memorandum requesting that NHTSA and EPA develop through notice and comment rulemaking a coordinated National Program to reduce greenhouse gas emissions of light-duty vehicles for model years 2017-2025. This proposal, consistent with the President's request, responds to the country's critical need to address global climate change and to reduce oil consumption. NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act, and EPA is proposing greenhouse gas emissions standards under the Clean Air Act. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, and represent a continued harmonized and consistent National Program. Under the National Program for model years 2017-2025, automobile manufacturers would be able to continue building a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices. EPA is also proposing a minor change to the regulations applicable to MY 2012-2016, with respect to air conditioner performance and measurement of nitrous oxides.

December 01, 2011 -- 76 FR 74854
Components of greenhouse gas emissions of light-duty vehicles (benzene, 1,3-butadiene, acetaldehyde, and naphthalene) were cited in the National Toxicology Program’s Report on Carcinogens (ROC).

Final Rule Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles EPA and NHTSA, on behalf of the Department of Transportation, are each finalizing rules to establish a comprehensive Heavy-Duty National Program that will reduce greenhouse gas emissions and fuel consumption for on-road heavy-duty vehicles, responding to the President's directive on May 21, 2010, to take coordinated steps to produce a new generation of clean vehicles. NHTSA's final fuel consumption standards and EPA's final carbon dioxide (CO2) emissions standards are tailored to each of three regulatory categories of heavy-duty vehicles: Combination Tractors; Heavy-duty Pickup Trucks and Vans; and Vocational Vehicles. The rules include separate standards for the engines that power combination tractors and vocational vehicles. Certain rules are exclusive to the EPA program. These include EPA's final hydrofluorocarbon standards to control leakage from air conditioning systems in combination tractors, and pickup trucks and vans. These also include EPA's final nitrous oxide (N2O) and methane (CH4) emissions standards that apply to all heavy-duty engines, pickup trucks and vans. EPA's final greenhouse gas emission standards under the Clean Air Act will begin with model year 2014. NHTSA's final fuel consumption standards under the Energy Independence and Security Act of 2007 will be voluntary in model years 2014 and 2015, becoming mandatory with model year 2016 for most regulatory categories. Commercial trailers are not regulated in this phase of the Heavy-Duty National Program. The agencies estimate that the combined standards will reduce CO2 emissions by approximately 270 million metric tons and save 530 million barrels of oil over the life of vehicles sold during the 2014 through 2018 model years, providing over $7 billion in net societal benefits, and $49 billion in net societal benefits when private fuel savings are considered. EPA is also finalizing provisions allowing light-duty vehicle manufacturers to use CO2 credits to meet the light-duty vehicle N2O and CH4 standards, technical amendments to the fuel economy provisions for light-duty vehicles, and a technical amendment to the criteria pollutant emissions requirements for certain switch locomotives.

Final Rule Hazardous Materials: Revision to the List of Hazardous Substances and Reportable Quantities PHMSA amends the Hazardous Materials Regulations by removing saccharin and its salts from the list of hazardous substances and reportable quantities. The Comprehensive Environmental Response, Compensation and Liability Act, requires PHMSA to list and regulate all hazardous substances designated by statute or by the U.S. Environmental Protection Agency (EPA). EPA recently removed saccharin and its salts from their list of hazardous substances through notice and comment rulemaking. This final rule simply harmonizes the lists to better enable shippers and carriers to identify the affected hazardous substances, comply with all applicable regulatory requirements, and make required notifications if the release of a hazardous substance occurs.

Proposed National Emissions Standards for Hazardous Air Pollutants: Ferroalloys Production The EPA is proposing amendments to the national emissions standards for hazardous air pollutants for Ferroalloys Production to address the results of the residual risk and technology review that the EPA is required to conduct under the Clean Air Act. These proposed amendments include revisions to particulate matter standards for electric arc furnaces, metal oxygen refining processes, and crushing and screening operations. The amendments also add emission limits for hydrochloric acid, mercury, polycyclic aromatic hydrocarbons, and formaldehyde from electric arc furnaces. Furthermore, the amendments expand and revise the requirements to control fugitive emissions from furnace operations and casting. Other proposed requirements related to testing, monitoring, notification, recordkeeping, and reporting are included. We are also proposing to revise provisions addressing periods of startup, shutdown, and malfunction to ensure that the rules are consistent with a recent court decision.

Proposed Certain High Production Volume Chemicals; Test Rule and Significant New Use Rule; Fourth Group of Chemicals EPA is proposing to issue a test rule under Toxic Substances Control Act (TSCA) section 4(a)(1)(B) to require manufacturers and processors of 23 high production volume (HPV) chemical substances to develop screening-level health, environmental, and fate data based on the potential for substantial exposures of workers and consumers to these chemicals. EPA is also proposing to issue simultaneously a significant new use rule (SNUR) for another 22 HPV chemical substances under TSCA section 5(a)(2). The SNUR would require persons to file a significant new use notice (SNUN) with EPA prior to manufacturing, importing, or processing any of these chemical substances for use in a consumer product or for any use, or combination of uses, that is reasonably likely to expose 1,000 or more workers at a single corporate entity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. EPA is also soliciting comment on a number of issues with regard to both the test rule and the SNUR.
