As required by the Clean Air Act, EPA has proposed actions for 11 nonattainment areas classified as moderate for the 2008 ozone National Ambient Air Quality Standards. These areas were required to attain the standards by July 20, 2018. After evaluating air quality monitoring data for the years 2015 - 2017, EPA is proposing that:
- Baltimore, MD, and Mariposa, CA, attained the standards by the attainment date;
- Both the Denver-Boulder-Greeley-Ft. Collins-Loveland, CO, and Sheboygan County, WI, areas are eligible for a 1-year attainment date extension to July 20, 2019; and
- Seven areas in CA, CT, IL, IN, NJ, NY, TX, and WI failed to attain the standards by their attainment date and do not qualify for a 1-year attainment date extension. These areas would be reclassified as Serious. The new attainment date for the reclassified areas would be July 20, 2021.
- Read the proposal.
- A summary fact sheet is available below.
