EPA is approving revisions to the Florida State Implementation Plan (SIP) to allow the State air pollution control agency to utilize exclusionary rules via general permits for the purpose of limiting potential to emit (PTE) criteria pollutants for certain source categories to less than the title V permitting major source thresholds. EPA is also approving under section 112(l) of the Clean Air Act (CAA) the same source-categories of the submitted regulations for limiting PTE of hazardous air pollutants (HAP) to less than title V permitting major source thresholds. These exclusionary rules allow facilities to compute potential emissions based on actual emissions or raw material usage for the following source categories: Asphalt concrete plants, bulk gasoline plants, emergency generators, surface coating operations, heating units and general purpose internal combustion engines, polyester resin plastic products, cast polymer operations; and mercury reclamation and recovery operations. On April 15, 1996, the State of Florida through the Department of Environmental Protection (DEP) submitted a SIP revision fulfilling the requirements necessary to utilize exclusionary rules to limit PTE of air pollutants in a federally enforceable manner. On August 6, 1996, the State of Florida submitted updates to the earlier submittal which also fulfill the requirements necessary to utilize exclusionary rules to limit PTE in a federally enforceable manner.
