Title: National Emission Standards for Hazardous Air Pollutants: Surface Coating of Metal Cans and Metal Coil Residual Risk and Technology Review 
Abstract:

This proposal will address the agency's residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Surface Coating of Metal Cans and the NESHAP for the Surface Coating of Metal Coil. These NESHAP were 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). The Surface Coating of Metal Cans NESHAP, subpart KKKK, was promulgated on November 13, 2003. The NESHAP controls emissions of organic HAP from can coating operations, including the storage, mixing and conveying of coating, thinners and cleaning materials used in, and the waste materials generated by, the coating operation. Metal can coating operations include the coating of metal cans, ends, metal crowns and closures. Due to the different types of coatings employed by the industry, the NESHAP includes emission limits for several separate subcategories, including: one- and two-piece draw and iron can body coating, sheet coating, three-piece can body assembly coating and end coating. The HAP emitted from the can coating operations primarily include glycol ethers, xylenes, hexane and methyl isobutyl ketone. The Surface Coating of Metal Coil NESHAP, subpart SSSS, was promulgated on June 10, 2002. The NESHAP controls emissions of organic HAP from metal coil coating operations. A coil coating operation is defined as the application system used to apply an organic coating to the surface of any continuous metal strip (at least 0.006 inch thick) that is packaged in a roll or coil, which includes the web unwind or feed station; the series of one or more coating stations and any associated curing ovens; the wet section/pretreatment operations; equipment and parts cleaning operations; the quenching operations; the mixing/thinning operations; and the storage and wastewater operations. The NESHAP regulates organic HAP and includes emission limits and operating limits that apply to the coating application stations, the curing ovens and the associated capture systems and control devices. The HAP emitted from the metal coil coating application operations and curing ovens include glycol ethers, xylenes, toluene and isophorone. This proposal will implement the residual risk review requirements of CAA section 112(f)(2) and the technology review requirements of CAA section 112(d)(6). CAA section 112(f)(2) directs EPA to revise the NESHAP if such revisions 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. 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, the EPA is obligated to complete the final action for both of these RTR by March 13, 2020. In consideration of this deadline, which also applies to 18 other RTR source categories, we established an internal schedule for this RTR to be proposed and finalized prior to the consent decree deadline.
