On August 31, 2020, U.S. EPA Administrator, Wheeler signed a direct final rule and parallel proposal that confirm for the public and state air agencies that nine areas attained the 1997 ozone National Ambient Air Quality Standards (NAAQS) by their respective attainment dates.  This action recognizes the effort these areas took to address ozone air quality and ensures that they will not be subject to consequences for not attaining the standards as required.  The areas are:

  1. Buffalo-Niagara Falls, New York;
  2. Jamestown, New York;
  3. Jefferson County, New York;
  4. Poughkeepsie, New York;
  5. Shoreline Sheboygan County, Wisconsin;
  6. Inland Sheboygan County, Wisconsin;
  7. Denver-Boulder-Greeley-Ft. Collins-Loveland, Colorado;
  8. San Francisco Bay Area, California; and,
  9. Ventura County, California.

This action confirms for the public and state air agencies that these areas are not subject to reclassification and other anti-backsliding consequences for failure to timely attain the 1997 ozone standards. Read a pre-publication version of the direct final rule and parallel proposal as well as a summary fact sheet below.
