Injection & Mining Division
LaSalle Building, 8th Floor
The Injection and Mining Division (IMD) has the responsibility of implementing two major federal environmental programs which were statutorily charged to the Office of Conservation: the Underground Injection Control (UIC) program with federal oversight from the Environmental Protection Administration (EPA) and the Surface Mining Program with federal oversight from the U.S. Department of the Interior, Office of Surface Mining.
Underground Injection Control Section >>
The Underground Injection Control (UIC) Section administers a regulatory and permit program to protect underground sources of drinking water from endangerment by the subsurface emplacement of both hazardous and non-hazardous fluids through deep well injection, and other oilfield waste disposal techniques.
Surface Mining Section >>
The Surface Mining Section is responsible for the regulation of exploration, development, and surface mining operations for coal and lignite, and protection of state and private lands.
