Wyoming Department of Environmental Quality (DEQ)

About us

Since 1973, the Wyoming Department of Environmental Quality (DEQ) has served as the state’s regulatory agency charged with protecting, conserving and enhancing Wyoming’s land, air and water for the benefit of current and future generations.
Our scientists and professional staff contribute to the quality of life in Wyoming through a combination of monitoring, permitting, inspection, enforcement, restoration and remediation activities that support responsible stewardship of our state’s natural resources.
We provide meaningful oversight to enable responsible economic development. The agency also works to restore previously polluted and hazardous sites for the benefit of everyone who calls Wyoming home or pays a visit to our great state.
