40 CFR 600.101-08 - General applicability.

EPA and NHTSA, on behalf of the Department of Transportation, are issuing final rules to further reduce greenhouse gas emissions and improve fuel economy for light-duty vehicles for model years 2017 and beyond. 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 improve fuel economy and reduce greenhouse gas emissions of light-duty vehicles for model years 2017-2025, building on the success of the first phase of the National Program for these vehicles for model years 2012-2016. This final rule, 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 finalizing Corporate Average Fuel Economy standards for model years 2017-2021 and issuing augural standards for model years 2022-2025 under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act. NHTSA will set final standards for model years 2022-2025 in a future rulemaking. EPA is finalizing greenhouse gas emissions standards for model years 2017-2025 under the Clean Air Act. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, and represent the continuation of a harmonized and consistent National Program. Under the National Program automobile manufacturers will 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 that are available today. EPA is also finalizing minor changes to the regulations applicable to model years 2012-2016, with respect to air conditioner performance, nitrous oxides measurement, off-cycle technology credits, and police and emergency vehicles.

The Environmental Protection Agency (EPA or Agency) is denying the petition of Plant Oil Powered Diesel Fuel Systems, Inc. (“POP Diesel”) to reconsider the final rules establishing emissions standards to reduce greenhouse gas emissions from on-road heavy-duty vehicles.

This action would establish more stringent vehicle emissions standards and reduce the sulfur content of gasoline beginning in 2017, as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The proposed gasoline sulfur standard would make emission control systems more effective for both existing and new vehicles, and would enable more stringent vehicle emissions standards. The proposed vehicle standards would reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. This would result in significant reductions in pollutants such as ozone, particulate matter, and air toxics across the country and help state and local agencies in their efforts to attain and maintain health-based National Ambient Air Quality Standards. Motor vehicles are an important source of exposure to air pollution both regionally and near roads. These proposed vehicle standards are intended to harmonize with California's Low Emission Vehicle program, thus creating a federal vehicle emissions program that would allow automakers to sell the same vehicles in all 50 states. The proposed vehicle standards would be implemented over the same timeframe as the greenhouse gas/fuel efficiency standards for light-duty vehicles, as part of a comprehensive approach toward regulating emissions from motor vehicles.

The Environmental Protection Agency (EPA or Agency) is providing notice that it is denying the petition of the Pacific Legal Foundation (PLF) to reconsider the final rules establishing greenhouse gas emissions standards from light duty motor vehicles for model years 2012-2016.
