EPA has published an interactive ozone map which identifies 241 counties in violation of the 2015 revised ozone standard based on 2012-2014 data. EPA will not designate areas as nonattainment based on the 2012-2014 data, but will likely use 2014-2016 data to determine area designations.

What this means to you
Ozone forms when oxides of Nitrogen (NOx) and volatile organic compounds (VOCs) combine in the presence of sunlight. EPA’s Lower ozone standards of 70 ppm will likely require tighter limits on NOx and VOCs.
