## Abstract

On July 11, 2002, Ohio submitted a plan which contained rules to control emissions of oxides of nitrogen (NO<INF>X</INF>) from electric generating units (EGU), non-EGUs and Portland Cement Kilns. The plan and associated rules represent a strategy submitted by the Ohio Environmental Protection Agency (Ohio EPA) in response to USEPA's October 27, 1998, NO<INF>X</INF> State Implementation Plan (SIP) Call and subsequent technical amendments. This direct final rule addresses the adequacy and acceptability of the Ohio plan, which we believe will have a major impact in reducing NO<INF>X</INF> and ozone in Ohio and in areas downwind from major sources of NO<INF>X</INF> emissions. USEPA believes the State's plan, which includes a NO<INF>X</INF> trading program, an energy efficiency/renewable energy feature and accommodates innovative technology projects, adequately addresses the requirements of the NO<INF>X</INF> SIP Call and meets the budget prescribed for Ohio. USEPA is taking final action today to approve the Ohio EPA plan.
