Proposed Revision to Florida's June 7, 2018 Redesignation Request and Maintenance Plan for the Hillsborough County SO2 Nonattainment Area

Submittal for Proposed Revision to Florida's June 7, 2018 Redesignation Request and Maintenance Plan for the Hillsborough County Sulfur Dioxide (SO2) Nonattainment Area

On April 16, 2019, the Florida Department of Environmental Protection (DEP) submitted an Implementation Plan (SIP) revision, under the Clean Air Act (CAA), to the U.S. Environmental Protection Agency (EPA).  This SIP submission proposes to revise Florida’s June 7, 2018, Redesignation Request and Maintenance Plan for the Hillsborough County SO2 Nonattainment Area. These amendments consist of incorporating recent permit revisions for Tampa Electric Company's Big Bend Station that restrict Big Bend Units 1 and 2 to firing only natural gas and amend the method of compliance used for the four-unit SO2 emissions cap to remove the continuous emission monitoring system requirement for Units 1 and 2 and require, instead, the use of procedures in 40 Code of Federal Regulations (CFR) Part 75 to calculate SO2 emissions.

On June 7, 2018, the DEP submitted a SIP revision, under the CAA, to the EPA.  Florida's proposed SIP revision consists of a request to the EPA to redesignate the portion of Hillsborough County that is designated as “nonattainment,” with respect to the 2010 revised SO2 National Ambient Air Quality Standard (NAAQS), to “attainment” and a request to approve an associated maintenance SIP that will ensure the continued attainment of the 2010 SO2 NAAQS in the area.
