Maximum Achievable Control Technology pollutant source standards

Under the Clean Air Act Amendments of 1990, the mandate is to establish, during the first phase, technology-based maximum achievable control technology (MACT) emission standards that apply to the major categories or subcategories of sources of the listed hazardous air pollutants (EPA, 1997). In addition, Title III provides for health-based standards that address the issue of residual risks due to air toxic emissions from the sources equipped with MACT and to determine whether the MACT standards can protect health with an ample margin of safety. 

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.

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...

The Clean Air Act (CAA) Amendments of 1990 list carbonyl sulfide as a hazardous air pollutant (HAP) generally known or suspected to cause serious health effects. Section 112(b) (1) of the CAA lists pollutants that are judged to be hazardous if emitted into the air. Carbonyl sulfide is included on this list. The statute calls for the identification of source categories that emit these HAPs, and the subsequent promotion of technology-based emission standards requiring compliance with maximum achievable control technology.

To limit the risk of hazardous air pollutant exposure over time, the EPA mandates that all major sources of HAP emissions operate under Maximum Achievable Control Technology (MACT) standards. The EPA intends to augment and add to the current list of MACT standards additionally, there are catch-aU regulations for all major sources of HAPs. One such example is the MACT Hammer, which allows states to implement MACT standards for industries not currently addressed by EPA definitions. A list of such MACT standards, including the Miscellaneous Organic NESHAP (MON), can be referenced at http //www.dep.state.pa.us/dep/deputate/airwaste/aq/permits/nes-haps/hammer table.pdf. 

National Emission Standards for Hazardous Air Pollutants (NESHAPS), Clean Air Act section 112 40 CFR Parts 61, 63, and 68. Includes an accidental release program, list of HAPS and sources, residual risk standards, and maximum achievable control technology (MACI standards. 

Hazardous Air Pollutants (HAPs). A list of 188 compounds and classes of compounds contained in Section 112 of the U.S. Glean Air Act. The U.S. Environmental Protection Agency (EPA) is required to develop MAGT (maximum achievable control technology) standards for any facility that is classified as a major source of HAPs. The EPA has authority to add or remove compounds from the HAP list. 

The 1990 CAA Amendments set new NESHAPS for 188 hazardous air pollutants. In addition, the Act required EPA to develop standards based on maximum achievable control technology, or MACT. Thus, the NESHAPS are commonly called the MACT standards. The law calls for EPA to review the technology-based MACT standards for each source category every eight years to determine whether any residual risk exists for the source category, and if necessary, revise the standards. Basically, the CAA requires major stationary sources to install pollution control equipment and to maintain that equipment in good working order. 

Infrequent measurements of water quality result in large statistical errors in estimation of performance versns WQS. When the available evidence indicates achieving WQS standards unlikely or impossible via application of source control technologies, the EPA imposes total maximum daily load (TDML) levels of individual pollutant discharge from point sources.
