Approval and Promulgation of Implementation Plans; OH

The EPA is approving revisions to sulfur dioxide (SO<INF>2</INF>) emissions regulations for the Lubrizol Corporation (Lubrizol). This facility is located in Lake County, Ohio. The Ohio Environmental Protection Agency (Ohio EPA) submitted Director's Final Findings and Orders (Orders) for the Lubrizol facility on November 9, 2000. These Orders are revisions to the Ohio State Implementation Plan (SIP). The revisions are the adjustment of six short-term emissions limits, the addition of an annual emissions limit, and the addition of a continuous emission rate monitoring system (CERMS) requirement for the Lubrizol facility. Three short-term emissions limits are relaxed and three short-term are tightened. There is no increase in the total potential short-term SO<INF>2</INF> emissions.
