Approval and Promulgation of State Implementation Plan; Indiana

In this action, EPA is approving the following as revisions to the Indiana ozone State Implementation Plan (SIP): a Rate-Of-Progress (ROP) plan to reduce Volatile Organic Compounds (VOC) emissions in Lake and Porter Counties by 15 percent (%) by November 15, 1996; a contingency plan to reduce VOC emissions by an additional 3% beyond the ROP plan, and an Indiana agreed order requiring VOC emission controls on Keil Chemical Division, Ferro Corporation, located in Lake County (Keil Chemical). The 15% ROP plan, 3% contingency plan, and the agreed order were submitted together on June 26, 1995. The plans and agreed order help to protect the public's health and welfare by reducing the emissions of VOC that contribute to the formation of ground-level ozone, commonly known as urban smog.
