Abstract
The Indiana Department of Environmental Management (IDEM) submitted a revised opacity rule to the EPA on October 21, 1999, as a requested revision to its State Implementation Plan (SIP). The revisions amend portions of Indiana's opacity rule concerning the start-up and shutdown of utility boilers, terminology used in discussing averaging periods, time periods for temporary exemptions, alternative opacity limits, and conflicts between visible emission readings and continuous opacity monitor (COM) data. The proposed rule and direct final rule were published in the November 30, 2001 Federal Register. After EPA received adverse comments, a direct final rule withdrawal was published on January 28, 2002. In this action, the EPA responds to the adverse comments and takes final action approving Indiana's SIP revision request.
