Abstract
EPA is approving temporary revised opacity limits for two processes at ALCOA Warrick Operations, which were submitted by the Indiana Department of Environmental Management (IDEM) on December 8, 1998, as amendments to its State Implementation Plan (SIP). ALCOA Warrick Operations is a primary aluminum smelter located in Newburgh, Indiana. The revised limits allow for higher opacity emissions during fluxing operations at two holding furnaces for a period of one year. The temporary limits for the #1 and #8 complexes expire on May 26, 1999, and June 15, 1999, respectively. Mass emissions limits are not being changed.
