NESHAPs

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. 

Under contract to the Systems and Strategy Development Division of the OAQPS/EPA, Systems Applications developed and applied modeling methods for the estimation of human exposure and dosage from airborne materials. The model is intended for a screening analysis of the impacts of chemicals under EPA review as potentially hazardous by the definitions of the NESHAPS program.

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...

NESHAP National Emissions Standards for Hazardous Air Pollutants emission standards for specific source categories that emit or have the potential to emit one or more hazardons air pollutants the standards are modeled on the best practices and most effective emission reduction methodologies in use at the affected facilities. 

The notification requirements do not apply if a building owner plans renovation projects that will disturb less than the NESHAP limits of 160 square feet of friable ACM on facility components or 260 linear feet of friable ACM on pipes (quantities involved over a one-year period). For renovation operations in which the amount of ACM equals or exceeds the NESHAP limits, notification is required as soon as possible.
