The United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
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.
The inventory was first proposed in a 1985 New York Times op-ed piece written by David Sarokin and Warren Muir, researchers for an environmental group, Inform, Inc. [2] Congress established TRI under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), and later expanded it in the Pollution Prevention Act of 1990 (PPA).
