EPA is taking direct final action under section 110 of the Clean Air Act (CAA), 42 U.S.C. 7410, to approve a revision to the Florida State Implementation Plan (SIP) submitted by the Florida Department of Environmental Protection (FDEP) on June 8, 2005. The revision is source-specific to the Lockheed Martin Aeronautics Company (LM), located in Pinellas County, Florida, and regards that facility's compliance with Florida's Surface Coating of Miscellaneous Metal Parts and Products Reasonably Available Control Technology rule, found at Florida Administrative Code (F.A.C.) Rule 62-296.513 (FL MMPP Rule). The source-specific SIP revision seeks to allow LM to employ as reasonably available control technology (RACT) the control techniques outlined in EPA's December 1997, "Aerospace Control Technique Guidelines" (EPA's Aerospace CTG), instead of the RACT described in the FL MMPP Rule. The source-specific SIP revision is approvable because it meets the standards for approval described in section 110(l) of the CAA.
