Four Corners Air Quality Group

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.

History of the Task Force and Group


The U.S. Department of Interior – Bureau of Land Management (BLM) and the U.S. Department of Agriculture – Forest Service (USFS) are currently responding to industry proposals for expanded development of oil and gas production in the region. There are two proposed coal-fired power plants: a 1,500 megawatt plant proposed on Navajo Nation lands and a 300 megawatt plant proposed north of Grants, New Mexico. Additionally, the population in the Four Corners region likely will continue to grow in coming years, resulting in even more air pollution and, specifically, more nitrogen oxide emissions.

In response to these challenges, the affected states, tribes and federal land managers in the region have come together to plan for control strategies for future air quality impacts from development. The concept of a Task Force emerged to enable a broad and inclusive collaborative process to regional air quality planning.


The next Four Corners Air Quality Group meeting will be held September 13, 2017 in Durango, CO.  There will also be a 2nd Four Corners Science Forum on Methane on September 12, 2017.
