State Regulations: South Dakota

State of South Dakota

The South Dakota Department of Environment and Natural Resources (SD DENR) is entrusted with the protection of public health, the conservation of natural resources, the protection of the environment, and the promotion economic development. The Oil and Gas Section is under the Minerals & Mining Program of the SD DENR Division of Environmental Services. The purpose of the Oil & Gas Section is to provide environmental regulation and to promote the development of oil and gas resources in a manner that will prevent waste, encourage the greatest economic recovery of oil and gas, and protect correlative rights, ground water resources, the environment, and human health. The Board of Minerals and Environment is the regulatory body for oil and gas regulations.

Disposal Practices and Applicable Regulations

Environmental protection regulations are found in Title 74 (Environment and Natural Resources) of the Administrative Rules of South Dakota. Article 74:10 (Oil and Gas Conservation) contains the oil and gas regulations. No specific regulations governing injection technologies (such as slurry injection and subfracture injection), annular disposal, or salt cavern disposal exist.

  • Pit Construction and Reclamation (74:10:03:13). All pits must be constructed, maintained, and reclaimed to prevent contamination of soil and waters of the state. Pits may not be used for the disposal, dumping, or storage of solid or hazardous waste, and other debris not commonly used in these operations.

  • Injection, Annular Disposal, and Salt Caverns.
    • Applications to employ injection technologies would be handled administratively. Any application would be carefully reviewed by the SD DENR (and the EPA, if aquifers are involved). If no protests or interventions are made after notice, the DENR can issue the permit. Otherwise, if any interventions are filed, the matter will be scheduled for hearing before the Board of Minerals and Environment.
    • Disposal of drilling pit contents down the annulus of a producing well would, in all likelihood, receive a negative recommendation from SD DENR staff upon referral to the Board of Minerals and Environment.
    • South Dakota has salt deposits in the northwest corner of the state, but in light of the inadequate thickness and purity of the salt, they have not been developed for storage or other purposes.

  • Other Regulations. The SD DENR administers the regulations governing solid waste, hazardous waste, surface water quality, surface water discharge, and ground water quality.
