Several new requirements related to underground storage tanks (USTs) have taken effect over the past few years. As fuel retailers, most NATSO members own and operate USTs for motor fuels and must comply with state and federal regulations. To help truck­stop and travel plaza owners stay cur­rent on UST requirements, NATSO has compiled a regulatory toolkit outlining the latest UST standards.

The toolkit outlines a number of key areas for operators. Including:

Secondary Containment. New and replaced tanks and piping must be secondarily contained with interstitial monitoring systems, and new dispenser systems must be equipped with under-dispenser containment that will contain regu­lated substances leaked from the primary containment until they are detected and removed and will prevent the release of regulated substances to the environment at any time during the operational life of the UST system. The rule also includes secondary containment testing requirements.

Walkthrough Inspections. The final rule requires periodic walk­through inspections to detect re­leases (for example, must check spill preventing equipment and fill caps every 30 days; must check containment sumps annually) and also includes additional require­ments for periodic spill, overfill and secondary containment mon­itoring.

Spill Containment Testing. Spill prevention equipment must be tested every three years.

Overfill Containment Inspec­tions. Ball float valves in vent lines have been eliminated as an option for satisfying overfill prevention requirements for new/replaced flow restrictors.

Operator Training. Requires owners/operators to designate at least one individual for each of three “classes” of operators, and those operators must be trained in certain areas.

Tank Compatibility with Alterna­tive Fuels. The final rule generally allows tank owners to demonstrate equipment compatibility with alter­native fuels (e.g., blends contain­ing greater than 10 percent ethanol or 20 percent biodiesel) through a listing by a nationally recognized association, such as Underwriters Laboratories, or based upon written equipment manufacturer approval.

Repairs. The final rule contains a number of requirements pertaining to repairs of leaking UST systems. Repaired secondary containment areas of tanks must be tested for tightness within 30 days of the repairs. Repaired spill or overfill prevention equipment must be tested or inspected to ensure it is operating properly within 30 days of the repair. In addition, second­ary containment areas of piping used for interstitial monitoring and containment sumps used for inter­stitial monitoring of piping must be tested for tightness within 30 days of the repair.

The final UST rule represented the first substantial revisions to the fed­eral UST regulations that were origi­nally promulgated in 1988. It is the culmination of a multi-year review of existing regulations and technological advances, as well as data regarding releases that have occurred over the past two decades.
