The Wyoming Department of
Environmental Quality (DEQ) was created by the Wyoming
Legislature in 1973 after passage of the Environmental
DEQ contributes to Wyoming’s quality of life through a combination of monitoring, permitting, inspection, enforcement and restoration/remediation activities which protect, conserve and enhance the environment while supporting responsible stewardship of our state’s resources.
Together, DEQ’s programs serve approximately 5,000 businesses annually operating over 28,000 individual facilities throughout the state.
By minimizing environmental pollution, enabling responsible economic development and restoring previously polluted and hazardous sites, DEQ provides benefits to not just these businesses, but to the entire population of Wyoming, as well as to all visitors who benefit from the quality of life we share in this great state.
DEQ is responsible for enforcing state and federal environmental laws, including:
Clean Air Act
l Clean Water Act
l National Pollutant Discharge Elimination System (NPDES)
l Environmental Quality Act
l Resource Conservation and Recovery Act (RCRA)
l Superfund Amendments and Title III Reauthorization Act (SARA)
