The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
EPA tests for fuel economy do not include electrical load tests beyond climate control, which may account for some of the discrepancy between EPA and real world fuel-efficiency. A 200 W electrical load can produce a 0.94 mpg (0.4 km/L) reduction in efficiency on the FTP 75 cycle test.
China's State Environmental Protection Administration (SEPA) upgraded emission controls again on 1 July 2004 to the Euro II standard. [31] More stringent emission standard, National Standard III, equivalent to Euro III standards, went into effect on 1 July 2007. [32] Plans were for Euro IV standards to take effect in 2010.
The U.S. Environmental Protection Agency's National Exposure Research Laboratory (NERL) is a national laboratory that conducts research and development to find improved methods, measurements, and models to assess and predict exposures of humans and ecosystems to pollutants and other conditions in air, water, soil, and food.
1970 – Reorganization Plan No. 3 created the Environmental Protection Agency (EPA) by Presidential Executive Order 1970 – Clean Air Act (Extension) . Major rewrite of CAA, setting National Ambient Air Quality Standards (NAAQS), New Source Performance Standards (NSPS) Hazardous Air Pollutant standards, and auto emissions tailpipe standards.
Section 300.110 establishes the National Response Team and its roles and responsibilities in the National Response system, including planning and coordinating responses to major discharges of oil or hazardous waste, providing guidance to Regional Response Teams, co-ordinating a national program of preparedness planning and response, and facilitating research to improve response activities.
The violations occurred between 2007–2008 and the state of Hawaii suggested these should be exempt from regulatory actions due to an 'exceptional event' (volcanic activity). Since 1980 the national concentration of SO 2 in the ambient air has decreased by 83%. [16] Annual average concentrations hover between 1–6 ppb.
