State Regulations: Missouri

State of Missouri

The Missouri Department of Natural Resources (DNR) Division of Geology and Land Survey administers the oil and natural gas laws and implements the state's underground injection control program as authorized under the Federal Safe Drinking Water Act (Geological Survey Program). The Missouri Oil and Gas Council is composed of the following agencies: the Division of Geology and Land Survey, the Division of Commerce and Industrial Development, the Missouri Public Service Commission, the Clean Water Commission, and the University of Missouri. Two other persons with knowledge of the oil and gas industry are appointed to the Council by the Governor with the advice and consent of the Senate.

Disposal Practices and Applicable Regulations

Title 10 (Department of Natural Resources), Division 50 (Oil and Gas Council) of the Code of State Regulations (CSR) contains the regulations relative to oil and gas operations.

  • Onsite Burial of Drill Cuttings. Due to the shallow depth of most of Missouri's wells, they are typically air-drilled. Thus, a minimal amount of cuttings are generated. Deeper wells have the potential to be drilled using mud rotary drilling methods. In these cases, drill cuttings are typically buried onsite.

  • Plugging Regulations. Applicable oil and gas drilling and production regulations (Title 10, Division 50, Chapter 2 of the CSR) do not address disposal of exploration and production waste by injection. However, plugging regulations do allow mud-laden fluids to be used in conjunction with cement, if approval is obtained in advance of plugging from the State Geologist (10 CSR 50-2.060).

  • Cavern Disposal. Missouri hosts no significant salt deposits. However, at one time, limestone caverns were evaluated for the storage of oil waste. The concept was rejected because good hydrologic evidence suggests that the oil waste would not remain in the cavern.
