Source categories, NESHAPs

NESHAP for Source Categories Organic HAPs from Synthetic Organic Chemical Manufacturing Industry (proposed) Yes EPA 1992... 

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 USEPA is responsible for creating and enforcing the NESHAPs for all hazardous air pollutant sources. The CAA states that new or existing major sources must have emission standards based on the maximum available control technology (M ACT) to reduce hazardous air pollutant emissions. The MACT standards are based on the performance of the best 12% of the control devices in the same source category. These MACT emissions requirements were extended in 1997 to cover wastewater biosolid incinerators at publicly owned treatment works (POTWs) that have the potential to discharge cadmium, lead, and mercury (Richman, 1997). 

NESHAP for Source Category Pulp Yes and Paper Production (proposed rule)... 

EPA. 1993b. U.S. Environmental Protection Agency. NESHAP for source category pulp and paper production. Proposed rule. Federal Register 58 66078. 

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.

Leak detection and repair (LDAR) provisions of the hazardous organic NESHAP (HON) rule of 40 CFR 63, Subparts H and I, apply to the emission of certain chemicals from facilities in this source category (see relevant subpart and 40 CFR 63.190 for details). 

Hexamethylene-1,6-diisocyanate is listed as a hazardous air pollutant (HAP) imder to Section 112 (b) of the Clean Air Act (CAA) (U.S. Congress 1990). The national emission standards for hazardous air pollutants (NESHAP) which were established pursuant to Section 112 of the CAA (as amended November 15, 1990), regulate specific categories of stationary sources that emit or have the potential to emit one or more HAPs. HDl is listed as a volatile HAP for wood furniture manufacturing operations in Title 40 of the Code of Federal Regulations (CFR), Part 63, Subpart JJ (EPA 1995).
