Underground Storage Tank Program

The Underground Storage Tank program will continue to function solely for UST and UST-related tasks. The goal of the UST Program is to protect human health and the environment by preventing releases of petroleum and hazardous substances from UST systems. The release of these regulated products into the environment threatens soil and groundwater resources and can cause explosive vapors to seep into confined spaces and occupied residences.

To help prevent contamination caused by leaking tanks, tank owners and operators must comply with state rules for UST’s. The objectives of the UST program are to ensure that UST systems are properly constructed and designed, installations, repairs, and removals are conducted and inspected by qualified individuals, active USTs are properly operated and monitored for releases, and USTs are properly closed and/or removed and the sites properly assessed for contamination.

Final Guidelines for the Evaluation of Underground Storage Tank Cathodic Protection Systems

The LDEQ Underground Storage Tank (UST) Division has finalized the guidance document titled “Guidelines for the Evaluation of Underground Storage Tank Cathodic Protection Systems” on July 15, 2020. All comments received during the draft review period were incorporated into the final document. In order to allow additional time for UST owners, CP testers, and certified workers to become familiar with the requirements contained in the guidance document, the guidance document will become effective on October 15, 2020.

• Guidelines for Evaluation of Underground Storage Tank Cathodic Protection Testing
