States Submit Comments on Proposed Ozone Standards


The comment period closed for the EPA's proposed update to the National Ambient Air Quality Standard (NAAQS) for ground-level ozone on March 17th. Based on recommendations from EPA’s science advisers and staff, the EPA is expected to announce a more stringent standard, likely in the range of 70 to 60 parts per billion, down from the 2008 standard of 75 parts per billion.  A stricter ozone requirement could be a challenge for some states and counties to attain, creating areas of noncompliance around the U.S. accompanied by a hefty price tag. State environmental agencies, the agencies responsible for developing compliance plans, had much to say about the EPA proposal and most states submitted comments.
