Welcome to the Four Corners Air Quality Group home page!

The Four Corners Air Quality Group is a forum for individuals interested in air quality to meet, learn about current conditions, review progress on mitigation of air quality impacts, and generally contribute to clean air in the Four Corners area.

The Group meets at least once per year and more often if circumstances warrant it. The Group is convened by the States of Colorado and New Mexico, with the support of a range of state, tribal and federal agencies.

To join the Four Corners Air Quality Group, please sign up. You will be notified of meetings and other important air quality information affecting the Four Corners area.
