State Regulations: Mississippi

State of Mississippi

The Mississippi State Oil and Gas Board (MSOGB), an independent agency, promulgates and enforces rules to regulate and promote oil and gas drilling, production, and storage so as to protect the coequal and correlative rights of all owners of interests and promulgates and enforces rules to regulate the disposal of nonhazardous oil field waste in an environmentally safe manner consistent with federal and state regulations. Otherwise, the Mississippi Department of Environmental Quality (MDEQ), through its Office of Pollution Control (OPC), administers the environmental protection laws.

Disposal Practices and Applicable Regulations

The Mississippi State Oil and Gas Board Rule Book contains the statewide rules and regulations governing underground injection control as well as the drilling rules for offshore wells (through the table of contents one can click and choose the exact rule that one wishes to view). The Mississippi Department of Environmental Quality (MDEQ) regulations governing, among others, hazardous waste, non-hazardous waste, land, and water are accessible by title and type through the MDEC homepage.

    • Injection not authorized by permit or rule is prohibited (Rule 63, Part 1).
    • Produced fluid disposal wells must meet regulatory requirements governing application (Rule 63, Part 5), construction (Rule 63, Part 6), mechanical integrity (Rule 63, Part 7), operating (Rule 63, Part 8), monitoring and reporting (Rule 63, Part 9), plugging and abandoning (Rule 63, Part 10), notification of down-hole work (Rule 63, Part 11), annular disposal (Rule 63, Part 12), and exemption of aquifers (Rule 63, Part 13).

    • The Board, after notice and hearing, is authorized to grant exceptions to the construction and operating provisions (Rule 63, Part 16).

  • Drilling Rules for Offshore Wells: Prevention of Waste, Including Pollution, and Waste Disposal (Rule OS-8).
    • Liquid Disposal. Liquid waste materials containing substances that may be harmful to aquatic life or wildlife, or otherwise injurious, shall be treated to avoid disposal of harmful substances into the waters. Drilling mud containing oil shall not be disposed of into the waters.
    • Solid Waste Disposal. Drill cuttings, sand, and other solids shall not be disposed of into the waters without prior approval of the Supervisor. Mud containers and other solid waste materials shall be incinerated or transported to shore for disposal.

  • Cavern Disposal. While Mississippi stores natural gas and liquefied petroleum gas in caverns formed in salt domes, no caverns have been used for exploration and production waste disposal in the state.
