Overview
The Wyoming Department of
Environmental Quality (DEQ) was created by the Wyoming
Legislature in 1973 after passage of the Environmental
Quality Act.
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.
