The cleanup of releases of petroleum products from underground storage tanks is required by both the federal government and the State of Arizona. The federal requirements are set forth in the Code of Federal Regulations and the state requirements are contained in the Arizona Revised Statutes and the Arizona Administrative Code.

If confirmed releases from underground storage tanks are not addressed by the owner or operators in the time frames required by the federal regulations and states rules and laws, the non-compliant UST facilities are referred to the Leaking Underground Storage Tank Enforcement Unit (LEU) for enforcement.

Enforcement actions initiated/taken by the LEU are conducted pursuant to the ADEQ Compliance and Enforcement Handbook. The actions range from the issuance of a Notice of Violation, to administrative orders and ultimately to a civil lawsuit in the Superior Court of Arizona if compliance cannot be achieved informally.
