EPA Approves Illinois and Indiana Air Quality Designations for 2012 PM 2.5 NAAQS

The Environmental Protection Agency (EPA) has approved Illinois' and Indiana's requests to revise the air quality designations for certain areas in the states. The designations, which were previously unclassifiable, will now be classified as unclassifiable/attainment, indicating that the areas meet the National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM 2.5).
