## Abstract

EPA is approving Indiana's rule revision to extend permit terms for the renewal of Federally Enforceable State Operating Permits (FESOPs) from five years to ten years. Indiana submitted this rule revision for approval on December 19, 2007. FESOPs apply to non-major sources that obtain enforceable limits to avoid being subject to certain Clean Air Act (Act) requirements, including the Title V operating permit program. Neither the Act nor its implementing regulations specify a permit-term requirement for FESOPs. This rule revision will provide relief to Indiana's resource burden of processing permit renewals. It will also allow the Indiana Department of Environmental Management (IDEM) to devote more resources to major source Title V permitting actions and permit modifications for both Title V and FESOP sources.
