Title: Control of Air Pollution From Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards 
Abstract: This action would establish more stringent vehicle emissions standards and reduce the sulfur content of gasoline as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The rule 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. 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 vehicle standards would also coordinate with the light-duty vehicle greenhouse gas standards for model years 2017-2025, creating a nationwide alignment of vehicle programs for criteria pollutant and greenhouse gases.

Statement of Need: States are working to attain National Ambient Air Quality Standards for ozone, PM, and NOx. Light-duty vehicles are responsible for a significant portion of the precursors to these pollutants and are large contributors to ambient air toxic pollution. In many nonattainment areas, by 2014, cars and light trucks are projected to contribute 30-45 percent of total nitrogen oxides (NOX) emissions, 20-25 percent of total volatile organic compound (VOC) emissions, and 5-10 percent of total direct particulate matter (PM2.5) emissions. Importantly, without future controls, by 2020 mobile sources are expected to be as much as 50 percent of the inventories of these pollutants for some individual urban areas. EPA has estimated that light-duty vehicles will contribute about half of the 2030 inventory of air toxic emissions from all mobile sources. The most recent National-Scale Air Toxics Assessment in 2005, mobile sources were responsible for over 50 percent of cancer risk and noncancer hazard.

Summary of the Legal Basis: The Clean Air Act section 202(a) provides EPA with general authority to prescribe vehicle standards, subject to any specific limitations elsewhere in the Act. In addition, section 202(k) provides EPA with authority to issue and revise regulations applicable to evaporative emissions of hydrocarbons from all gasoline-fueled motor vehicles. EPA is also using its authority under section 211(c) of the Clean Air Act to address gasoline sulfur controls.

Alternatives: The rulemaking proposal will include an evaluation of regulatory alternatives that can be considered in addition to the Agency's primary proposal.

Anticipated Costs and Benefits: Detailed analysis of economy-wide cost impacts, emissions reductions, and societal benefits will be performed during the rulemaking process.

Risks: Approximately 159 million people currently live in counties designated nonattainment for one or more of the NAAQS, and this figure does not include the people living in areas with a risk of exceeding the NAAQS in the future. These people experience unhealthy levels of air pollution, which are linked with respiratory and cardiovascular problems and other adverse health impacts that lead to increased medication use, hospital admissions, emergency department visits, and premature mortality. The reductions in ambient ozone and PM2.5 that would result from the proposed Tier 3 standards would provide significant health benefits. In the absence of additional controls such as Tier 3 standards, many counties will continue to have ambient ozone and PM2.5 concentrations exceeding the NAAQS in the future. In addition, more than 50 million people live, work, or go to school in close proximity to high-traffic roadways, and the average American spends more than one hour traveling along roads each day. Exposure to traffic-related pollutants has been linked with adverse health impacts such as respiratory problems (particularly in asthmatic children) and cardiovascular problems. The Tier 3 standards would reduce criteria pollutant and air toxic emissions from cars and light trucks, which continue to be a significant contributor to air pollution directly near roads.
