National Emission Standards for Hazardous Air Pollutants: Miscellaneous Coating Manufacturing

摘要

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for miscellaneous coating manufacturing facilities. The final rule establishes emission limits and work practice requirements for new and existing miscellaneous coating manufacturing operations, including process vessels, storage tanks, wastewater, transfer operations, equipment leaks, and heat exchange systems, and implements section 112(d) of the Clean Air Act (CAA) by requiring all major sources to meet hazardous air pollutant (HAP) emission standards reflecting application of the maximum achievable control technology (MACT). The HAP emitted from miscellaneous coating manufacturing facilities include toluene, xylene, glycol ethers, methyl ethyl ketone, and methyl isobutyl ketone. Exposure to these substances has been demonstrated to cause adverse health effects such as irritation of the lung, eye, and mucous membranes, effects on the central nervous system, and cancer. We do not have the type of current detailed data on each of the facilities and the people living around the facilities covered by the final rule for this source category that would be necessary to conduct an analysis to deter
