Illinois DNR's Office of Mines and Minerals permits the State's coal and aggregate mining industries and enforces various acts that govern these industries.
Oil and Gas Resource Management is the regulatory authority in Illinois for permitting, drilling, operating, and plugging oil and gas production wells. The office implements the Illinois Oil and Gas Act and enforces standards for the construction and operation of related production equipment and facilities. The office will also have responsibility for the regulation of high volume horizontal hydraulic fracturing operations under the newly enacted Hydraulic Fracturing Regulatory Act. In addition, the Oil and Gas Resource Management regulates the injection of fluids into Class II underground injection wells, through the Underground Injection Control (UIC) Program, and cleans up abandoned well sites through the Plugging Restoration Fund (PRF) and Landowner Grant Programs.
