Riepilogo

On July 6, 2007, the Indiana Department of Environmental Management (IDEM) submitted a request to EPA to amend its State Implementation Plan (SIP) to add incentives for regulatory flexibility for participants in its Environmental Stewardship Program (ESP) and Comprehensive Local Environmental Action Network (CLEAN) Community Challenge Program. Indiana requested that EPA approve the following for ESP and CLEAN members: The incorporation by reference of certain incentives under the National Environmental Performance Track (NEPT) Program, monthly averaging of volatile organic compound (VOC) coating limits, and the processing of pollution prevention projects as minor permit revisions. For the reasons discussed below, EPA is proposing to disapprove these three incentives.
