API's comments on EPA's proposal to retain the current National Ambient Air Quality Standards NAAQS

API filed detailed comments on EPA’s proposal to retain the current National Ambient Air Quality Standards (NAAQS) for nitrogen oxides. Nitrogen oxides, a precursor to ground-level ozone formation, are generated by many of our industry operations, which have already spent hundreds of millions of dollars to reduce those emissions.  API’s comments concurred with the conclusion of the EPA Administrator not to change the standards, arguing that “the current body of scientific evidence and the results of quantitative analyses support the degree of public health protection provided by the current 1-hour and annual primary NO2 standards.”  API further stated that, “… the Administrator could consider whether relaxing them would be appropriate.”  EPA is expected to finalize the standards, as proposed, in 2018.
