Final National Emission Standards for Hazardous Air Pollutants: Miscellaneous Coating Manufacturing Residual Risk and Technology Review

The U.S. Environmental Protection Agency (EPA) is taking final action on the residual risk and technology review (RTR) conducted for the Miscellaneous Coating Manufacturing (MCM) source category regulated under national emission standards for hazardous air pollutants (NESHAP). These final amendments also address emissions during periods of startup, shutdown, and malfunction (SSM), including clarifying regulatory provisions for certain vent control bypasses, provisions for electronic reporting of performance test results, performance evaluation reports, compliance reports, and Notification of Compliance Status (NOCS) reports; and provisions to conduct periodic performance testing of oxidizers used to reduce emissions of organic hazardous air pollutants (HAP).

A fact sheet of the final rule is below. For more information about the rule, visit the regulation page for Miscellaneous Coating Manufacturing.
