Control of Hazardous Air Pollutants from Mobile Sources (Us Environmental Protection Agency Regulation) (Epa) (2018 Edition)


Book Description

Control of Hazardous Air Pollutants From Mobile Sources (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Control of Hazardous Air Pollutants From Mobile Sources (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is adopting controls on gasoline, passenger vehicles, and portable fuel containers (primarily gas cans) that will significantly reduce emissions of benzene and other hazardous air pollutants ("mobile source air toxics"). Benzene is a known human carcinogen, and mobile sources are responsible for the majority of benzene emissions. The other mobile source air toxics are known or suspected to cause cancer or other serious health effects. We are limiting the benzene content of gasoline to an annual refinery average of 0.62% by volume, beginning in 2011. In addition, for gasoline, we are establishing a maximum average standard for refineries of 1.3% by volume beginning on July 1, 2012, which acts as an upper limit on gasoline benzene content when credits are used to meet the 0.62 volume % standard. We are also limiting exhaust emissions of hydrocarbons from passenger vehicles when they are operated at cold temperatures. This standard will be phased in from 2010 to 2015. For passenger vehicles, we are also adopting evaporative emissions standards that are equivalent to those currently in effect in California. Finally, we are adopting a hydrocarbon emissions standard for portable fuel containers beginning in 2009, which will reduce evaporation and spillage of gasoline from these containers. These controls will significantly reduce emissions of benzene and other mobile source air toxics such as 1,3-butadiene, formaldehyde, acetaldehyde, acrolein, and naphthalene. There will be additional substantial benefits to public health and welfare because of significant reductions in emissions of particulate matter from passenger vehicles.

National Air Toxics Program


Book Description

The 1990 Clean Air Act Amendments (CAA) required the EPA to take specific actions to reduce emissions and risks from air toxics. Air toxics (also known as hazardous air pollutants or HAPs) are pollutants known to cause or suspected of causing cancer as well as respiratory, neurological, reproductive and other serious health effects. Air toxics are emitted by mobile sources (e.g., cars, trucks and construction equipment); large or major sources (e.g., factories and power plants); smaller, or area, sources (e.g., gas stations and dry cleaners); and background sources (e.g., longrange transport of pollution and natural emissions sources such as wildfires). Examples of air toxics include benzene, found in gasoline; perchloroethylene, emitted from some dry cleaning facilities; and methylene chloride, used as a solvent by several industries. Congress expressed under CAA section 112(k) that emissions of air toxics, individually or in the aggregate, may present significant risks to public health in urban areas and directed the U.S. Environmental Protection Agency (EPA) to develop a strategy to reduce these risks. Considering the large number of persons exposed and the risks of carcinogenic and other adverse health impacts from HAPs, the EPA believed that to reduce public health risks in urban areas, aggregated exposures from all sources had to be addressed. Therefore, it developed the Integrated Urban Air Toxics Strategy in 1999, using all available authorities, for reducing cumulative public health risks in urban areas posed by the aggregated exposures from all sources, including major stationary sources, smaller area stationary sources and mobile sources. The EPA also recognized that national regulations alone would not be enough to address all of the issues, particularly those affecting urban areas.
