## Abstract

The EPA is approving as a revision to the Indiana particulate matter (PM) State Implementation Plan (SIP) emission control regulations that pertain to Knauf Fiber Glass (Knauf) which is located in Shelbyville, Indiana, as requested by the State of Indiana on October 17, 2002. This submission makes changes to federally enforceable Indiana air pollution control rules. The rule revisions modify the PM emissions limits adopted by the State in the 1980s which are part of the current Indiana SIP. The revised rules delete references to equipment no longer in use by Knauf and update names of remaining equipment. Because the revised rules reduce both allowable emissions and the allowable emissions rate and reflect current operations atthe Knauf facility, EPA approval of these revisions should not result in an adverse impact on air quality.
