The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the District of Columbia (the District). The District's SIP revision satisfies the volatile organic compound (VOC) reasonably available control technology (RACT) requirements under the 2008 8-hour ozone national ambient air quality standard (NAAQS). The District will address RACT for nitrogen oxides (NO<INF>X</INF>) in a separate SIP submission. The District's RACT submittal for the 2008 ozone NAAQS includes certification that for certain major sources, previously adopted VOC RACT controls in the District's SIP that were approved by EPA under the 1979 1-hour and 1997 8-hour ozone NAAQS are based on the currently available technically and economically feasible controls, and continue to represent RACT for implementation of the 2008 8-hour ozone NAAQS; a listing of the Control Techniques Guidelines (CTGs) already adopted into the District's SIP, and a listing of those categories of sources subject to CTGs which do not exist in the District and the location of prior negative declarations previously submitted and approved by EPA. The District's SIP submittal also includes an update to the 2002 Mobile Equipment Repair and Refinishing (MERR) rule to incorporate the Ozone Transport Commission's (OTC) 2009 Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations regulations (MVMERR) rule adopted by the District in 2016. EPA is addressing the 2009 MVMERR rule in a separate rulemaking action as it is not related to the 2008 VOC RACT SIP revision and does not impact EPA's proposed approval. This action is being taken under the Clean Air Act (CAA).
