National Emission Standards for Hazardous Air Pollutants (NESITAP)... 

Once a substance is designated by EPA as a ha2ardous air pollutant (HAP), EPA has to promulgate a NESHAP (National Emission Standard for Ha2ardous Air Pollutants), designed to protect pubHc health with an ample margin of safety.

Finally, Sec. 112 of the Clean Air Act required that EPA pronml-gate National Emission Standards for Hazardous Air Pollutants (NESHAPs). Between 1970 and 1989, standards were promulgated for asbestos, beiylhum, mercuiy, vinyl chloride, benzene, arsenic, radionuclides, and coke-oven emissions. 

Before the U.S. Clean Air Act Amendments of 1990 (3), hazardous air pollutants were regulated through federal promulgation of the National Emission Standards for Hazardous Air Pollutants (NESHAPS). The EPA listed only eight hazardous air pollutants under NESHAPS.

Air toxics regulations apply to several parts of the pulp and paper milling process. National Emission Standards for Hazardous Air Pollutants (NESHAP) have been developed expressly for two processes of the pulp and paper industry. These standards establish process-based maximum achievable control technologies (MACT) for major sources, which are defined as facilities that emit or have the potential to emit 10 t per year or more of any hazardous air pollutant (HAP) or 25 t per year or more of any combination of HAPs.

A National Emission Standard for Hazardous Air Pollutants (NESHAP) for new and existing hydrochloric acid process steel pickling lines and HC1 regeneration plants pursuant to Section 112 of the Clean Air Act as amended in November 1990 has been proposed (62 FR 49051, September 18,1997). The purpose of this rulemaking is to reduce emissions of HC1 by about 8360 megagrams per year.

Boatbuilders who use composites have, at most, just one more year before they have to reduce emissions to meet National Emission Standards for Hazardous Air Pollutants (NESH AP), also known as Maximum Achievable Control Technology (MACT) standards. By 23rd Aug. 2004, most boat manufacturing facilities subject to NESHAP must comply with 40 Code of Federal Regulations (CFR) Part 63, Subpart VVW. The deadline applies to existing boat manufacturing facilities that are major sources of hazardous air pollutants (HAPs). Existing sources are those that commenced construction on or before July 14, 2000. ( New sources , those that commenced construction after this date, must comply with emission limits at startup.) Major sources are facilities that have the potential to... 

Facilities that produce PETP will have an additional six months, until August 27, to comply with new equipment leak standards, it is briefly reported. The EPA has said an extension of the February 27 compliance deadline was necessary because the agency is reviewing petitions filed by PETP producers for reconsideration of the 1996 standards, which are part of the National Emission Standard for Hazardous Air Pollutants for group IV polymers and resins.

EPA regulates 3,3 -dichlorobenzidine under the Clean Air Act (CAA) and has designated 3,3 -dichloro-benzidine as a hazardous air pollutant (HAP) (EPA 1994 U S. Congress 1990). The major source category for which the national emissions standards for new stationary sources are applicable to 3,3 -dichlorobenzidine emissions is the synthetic organic chemicals manufacturing industry (SOCMl)—equipment leaks (EPA 1994).
