In a letter dated June 7, 2018, the State of Florida, through the Florida Department of Environmental Protection (FDEP), submitted a request for the Environmental Protection Agency (EPA) to redesignate the Hillsborough County sulfur dioxide (SO<INF>2</INF>) nonattainment area (hereinafter referred to as the "Hillsborough County Area" or "Area") to attainment for the 2010 1-hour SO<INF>2</INF> primary national ambient air quality standard (NAAQS or standard) and to approve an accompanying State Implementation Plan (SIP) revision containing a maintenance plan for the Area. The submittal was received by EPA on June 12, 2018. Through a letter dated April 16, 2019, FDEP submitted a revision to the June 7, 2018, redesignation request and SIP revision asking EPA to incorporate certain conditions into the SIP from a recent permit revision applicable to the Tampa Electric Company--Big Bend Station (Big Bend) power plant. The submission was received by EPA on April 25, 2019. EPA is proposing to determine that the Hillsborough County Area attained the 2010 1-hour SO<INF>2</INF> NAAQS by its applicable attainment date of October 4, 2018; to approve the SIP revision containing the State's plan for maintaining attainment of the 2010 1-hour SO<INF>2</INF> standard and to incorporate the maintenance plan into the SIP; to redesignate the Hillsborough County Area to attainment for the 2010 1-hour SO<INF>2</INF> NAAQS; and to incorporate into the SIP certain permitting conditions applicable to Big Bend, including a condition that lowers the SO<INF>2</INF> emissions cap and a condition that restricts fuel use at two electric generating units to natural gas.
