Reviewing National Ambient Air Quality Standards (NAAQS)

Ozone (O3) Standards - Federal Register Notices from Current Review

Over the course of each NAAQS review, EPA publishes notices in the Federal Register for a variety of activities:  the kick-off workshop and call for information, CASAC meetings, availability of pre-rulemaking documents and opportunities for comment on these documents, as well as proposed and final rulemaking decisions and public hearings on a proposed rulemaking decision.
