In 1978, the Legislature consolidated five state agencies into the Department of Natural Resources. The agencies which were consolidated at that time included the Mississippi Geological Survey, the Board of Water Commissioners, the Air and Water Pollution Control Commission, the Park Commission, and the Mineral Lease Commission. In the 1989 Legislative session, the Department of Environmental Quality was established to replace the Department of Natural Resources, and the Office of Recreation and Parks was moved to the Mississippi Department of Wildlife, Fisheries, and Parks.

The Mississippi Commission on Environmental Quality is empowered to formulate Department policy, enforce rules and regulations, receive funding, conduct studies for using the State's resources, and to discharge its duties, responsibilities and powers as necessary. The Commission's seven members are appointed by the Governor to staggered seven-year terms.
