This October 2015 document provides an outline of how the EPA will work with state, federal and tribal air agencies to carry out the duties of air quality management (AQM) for the revised ozone standards. EPA will do this in a manner that maximizes common sense, flexibility and cost-effectiveness while abiding by the legal requirements of the Clean Air Act (CAA).

It outlines commitments that the EPA will endeavor to meet, and our expectations of our air agency partners with regard to some of these issues. It is not intended to be a comprehensive communication on implementing the revised ozone standards, nor does it constitute new guidance.
