Disposal Practices and Applicable Regulations

The Oil and Gas Conservation Commission (OGCC) has promulgated regulations governing drilling mud disposal in Title 12, Chapter 7 of the Arizona Administrative Code (AAC). All other waste disposal, from the state perspective, is regulated by the Arizona Department of Environmental Quality (ADEQ) under Title 18 (various Chapters) of the AAC.

  • Drilling Mud Disposal. Drilling mud shall be disposed of by either recycling or commercial offsite disposal,(R12-7-108.E). The regulations allow certain water-based mud to be disposed of by evaporation and subsequent leveling of the pits (R12-7-108.E). The mud shall contain no more than one pound per barrel of thinner for each 25 pounds per barrel of barite or hematite. The mud shall not contain certain chromium compounds.

  • Other ADEQ Regulations. The ADEQ has promulgated regulations governing solid waste management, including disposal through landfilling and incineration (Title 18, Chapter 13 of the AAC). The hazardous waste management regulations adopt the federal exclusion from the definition of hazardous waste for oil and gas exploration and production waste (Title 18, Chapter 8 of the AAC).
