## Abstract

On October 25, 1994, the Indiana Department of Environmental Management (IDEM) submitted a Federally Enforceable State Operating Permit Program (FESOP) regulation and an Enhanced New Source Review (NSR) regulation as requested revisions to the State Implementation Plan (SIP). USEPA made a completeness finding in a letter dated November 25, 1994. In this rule USEPA approves Indiana's FESOP regulation, as a SIP revision, because the regulation provides an acceptable mechanism for establishing federally enforceable State operating permits for the purpose of creating federally enforceable limitations on the potential to emit of certain pollutants regulated under the Clean Air Act (Act). This program allows a number of small sources to be exempt from further operating permit review otherwise required by the Act. In this action, USEPA also approves Indiana's Enhanced NSR regulation. Sources subject to the State construction permit rule will have the opportunity to satisfy its State operating permit requirements by opting into this preconstruction rule. In the proposed rules section of this Federal Register, USEPA is proposing approval of and soliciting public comment on these requested SIP revisions. If adverse comments are received on this direct final rule, USEPA will withdraw this final rule and address the comments received in a final rule on the related proposed rule which is being published in the proposed rules section of this Federal Register. Unless this final rule is withdrawn, no further rulemaking will occur on this requested SIP revision.
