The Missouri Air Conservation Commission (MACC) administers the Missouri Air Conservation Law (Chapter 643, Revised Statutes of Missouri). Created in 1965 by the Missouri General Assembly, the commission consists of seven members appointed by the governor. Commissioners serve four-year terms and meet at least nine times a year. Agendas vary, but they typically include public hearings, actions on rules, requests for variances and/or work related to compliance issues. All meetings are open to the public, and the commission welcomes comments.

The commission's operating policy describes its structure, training provided to commissioners and a member's roles and responsibilities.

Among the commission's duties:

  • Adopting, amending, and rescinding rules.
  • Making decisions on appeals from enforcement orders and permit conditions.
  • Beginning legal actions to compel compliance with rules.
  • Assigning duties to local air pollution control agencies.
  • Listing regions as attainment (when air quality in an area meets all standards) or non-attainment areas (if air monitors detect too much of a pollutant) based on the National Ambient (outdoor) Air Quality Standards.
  • Approving overall plans for meeting the national standards in listed non-attainment areas.

The latest public hearing notice appears online, and anyone may review it via our Public Notices and Comment Periods webpage. You also may request to receive notices of commission meetings and public hearings by calling the Air Pollution Control Program at 573-751-4817 or by subscribing to the department's list for broadcast emails.
