EPA is approving a revision to the Florida State Implementation Plan (SIP) submitted on December 26, 1996, by the State of Florida through the Florida Department of Environmental Protection (FDEP). This source-specific revision amends the SIP to include a variance granted to the Harry S. Truman Animal Import Center (HSTAIC) for its incinerator facility located in Monroe County, Florida. The variance allows HSTAIC to operate under the particulate matter standard applicable to biological waste combustion facilities.
