EPA Proposes Determination of Attainment for Chicago-Gary-Lake County Ozone Nonattainment Area, Approves Indiana's NOx RACT Waiver Request

The Environmental Protection Agency (EPA) is proposing to determine that the Chicago-Gary-Lake County, Illinois-Indiana ozone nonattainment area has met the 1997 eight-hour ozone National Ambient Air Quality Standard, based on quality-assured monitoring data from 2006-2008. The agency is also approving Indiana's request to exempt certain sources of nitrogen oxides in Lake and Porter Counties from Clean Air Act requirements for Reasonably Available Control Technology.
