Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Amendments to the Control of Emissions of Volatile Organic Compounds From Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations

요약

The Environmental Protection Agency (EPA) is approving a revision to the District of Columbia's (the District) state implementation plan (SIP) submitted on August 29, 2018. The portion of the District's SIP revision being approved is an update to the 2002 Mobile Equipment Repair and Refinishing (MERR) model rule to incorporate the Ozone Transport Commission's (OTC) 2009 Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations regulations (MVMERR) model rule, which was adopted by the District in 2016. The MVMERR rules establish volatile organic compounds (VOC) content limits for coating and cleaning solvents used in vehicle refinishing and standards for coating application, work practices, monitoring, and recordkeeping. The remaining part of the August 29, 2018 SIP revision addressed the District's VOC Reasonably Available Control Technology (RACT) requirements for the 2008 ozone national ambient air quality standards (NAAQS). EPA will address the VOC RACT portion of the SIP revision in a separate rulemaking action. This action is being taken under the Clean Air Act (CAA).
