This proposal will address the Agency’s residual risk and technology review (RTR) of three National Emission Standards for Hazardous Air Pollutants (NESHAP): Surface Coating of Metal Furniture, Surface Coating of Large Appliances, and Printing, Coating, and Dyeing of Fabric and Other Textiles. These NESHAPs 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 Furniture NESHAP, subpart RRRR, was promulgated on May 23, 2003. The NESHAP controls emissions of organic HAP from all coating operations, including: all storage containers and mixing vessels in which coatings, thinners, and cleaning materials are stored or mixed; all manual and automated equipment; and all pumps and piping within the affected source used for conveying coatings, thinners, and cleaning materials. The primary HAP emitted from these operations include xylenes, glycol ethers, and ethyl benzene.

The Surface Coating of Large Appliances NESHAP, subpart NNNN, was promulgated on July 23, 2002. The NESHAP controls emissions of organic HAP from surface preparation of the large appliances or parts including: application of the coatings; flash off and drying/or curing of the applied coating; cleaning of equipment used in surface coating; storage of coatings, thinners, and cleaning materials and handling and conveyance of waste materials generated by the surface coating operations. The primary HAP emitted from these operations include glycol ethers, xylenes, toluene, methanol, ethyl benzene, methylene chloride, and methyl isobutyl ketone.

The Printing, Coating, and Dyeing of Fabric and Other Textiles NESHAP, subpart OOOO, was promulgated on July 11, 2002. The NESHAP controls emissions of organic HAP from three subcategories: (1) coating and printing, (2) slashing, and (3) dyeing and finishing operations. The HAP emitted from these operations include toluene, phenol, methanol, n, n-dimethyl formamide, xylenes and trichloroethylene.

This action will implement 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. The EPA currently plans to complete this action by December 31, 2018.
