Approval and Promulgation of Implementation Plans; Indiana

On October 25, 1994 and April 29, 1997, the Indiana Department of Environmental Management (IDEM) submitted proposed revisions to its State Implementation Plan (SIP). The submission contains revisions to the Indiana SIP's general provisions (326 IAC 1-1; 326 IAC 1-2), the applicability criteria of the rule for malfunctions (326 IAC 1-6), and the applicability criteria for state construction and operating permit requirements (326 IAC 2-1). The submission also revises Indiana's construction permit program (326 IAC 2-1) and its ``Permit no defense'' regulation (326 IAC 2-1). With this rule, EPA is approving this SIP submission because it is consistent with the Clean Air Act and applicable regulations. EPA has proposed approval and solicited comment on this direct final action through the proposed rule previously published in the Federal Register at (62 FR 7193); if adverse comments are received, EPA will withdraw the direct final rule and address the comments received in a new final rule. Unless this direct final rule is withdrawn, no further rulemaking will occur on this requested SIP revision.
