View Rule

This final rule addresses the agency's residual risk and technology reviews (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Coating Manufacturing. This NESHAP was promulgated pursuant to section 112(d) of the Clean Air Act (CAA) and established emission limitations and work practice requirements based on maximum achievable control technology (MACT) for controlling emissions of hazardous air pollutants (HAP). Miscellaneous Coating Manufacturing NESHAP, subpart HHHHH, was promulgated pursuant to section 112(d) of the Clean Air Act (CAA) on December 11, 2003 and covers facilities that manufacture paints, inks, and adhesives. The NESHAP controls emissions of HAP from process vessels, storage tanks, equipment leaks, wastewater streams, transfer operations and heat exchange systems. The organic HAP emitted from these sources include, but are not limited to, toluene, xylenes and methyl isobutyl ketone. This action implements the residual risk review requirements of CAA section 112(f)(2) and the technology review requirements of CAA section 112(d)(6). The statute directs the EPA to promulgate emission standards under CAA 112(f)(2) if such standards are required to provide an ample margin of safety to protect public health or to prevent, taking relevant factors into account, an adverse environmental effect. Any such standards are to be promulgated within 8 years after promulgation of MACT standards under CAA section 112(d). CAA section 112(d)(6) requires the EPA to review and revise the MACT standards as necessary, taking into account developments in practices, processes and control technologies, no less often than every 8 years. Pursuant to a court order related to the review of 13 source categories, the EPA must complete seven final RTR actions by December 31, 2018, and six additional RTR actions by June 30, 2020. In consideration of this deadline, we established an internal schedule for this RTR to be proposed and finalized prior to the court order deadline. The proposed rule did not make any changes based on the risk and technology reviews. The EPA did propose to amend provisions addressing periods of startup, shutdown and malfunction, require electronic reporting and require periodic performance testing every 5 years for facilities using add-on controls to demonstrate compliance with the NESHAP.
