In a letter dated December 9, 2019, the Commonwealth of Kentucky, through the Kentucky Division of Air Quality (KDAQ) on behalf of the Louisville Metro Air Pollution Control District (LMAPCD), submitted a request for the Environmental Protection Agency (EPA) to redesignate the Jefferson County sulfur dioxide (SO<INF>2</INF>) nonattainment area (hereinafter referred to as the "Jefferson County Area" or "Area") to attainment for the 2010 1-hour SO<INF>2</INF> primary national ambient air quality standard (NAAQS) and to approve an accompanying state implementation plan (SIP) revision containing a maintenance plan for the Area. EPA is proposing to determine that the Jefferson County Area has attained the 2010 1-hour SO<INF>2</INF> NAAQS; to approve the SIP revision containing the Commonwealth's plan for maintaining attainment of the 2010 1-hour SO<INF>2</INF> standard and to incorporate the maintenance plan into the SIP; and to redesignate the Jefferson County Area to attainment for the 2010 1-hour SO<INF>2</INF> NAAQS.
