R311-203-5. UST Testing Requirements

  (a) Tank tightness testing. The testing method must be able to test the UST system at the maximum level that could contain regulated substances. Tanks with overfill prevention devices that prevent product from entering the upper portion of the tank may be tested at the maximum level allowed by the overfill device.

  (b) Spill prevention equipment. An individual who conducts a test of spill prevention equipment to meet the requirements of 40 CFR 280.35(a)(1)(ii) shall report the test results using:

  (1) the form "Utah Spill Prevention Test", or

  (2) the form "Appendix C-3 Spill Bucket Integrity Testing Hydrostatic Test Method Single and Double-Walled Vacuum Test Method", found in PEI RP1200, "Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities", or

  (3) another form approved by the Director.

  (c) Containment sump testing. An individual who conducts a test of a containment sump used for interstitial monitoring to meet the requirements of 40 CFR 280.35(a)(1)(ii) or a test of a piping containment sump or under-dispenser containment to meet the requirements of R311-206-11 shall report the test results using:

  (1) the form "Utah Containment Sump Test", or

  (2) the form "Appendix C-4 Containment Sump Integrity Testing Hydrostatic Testing Method", found in PEI RP1200, or

  (3) another form approved by the Director.

  (d) When a sump sensor is used as an automatic line leak detector, the secondary containment sump shall be tested for tightness annually according to the manufacturer's guidelines or standards, or by another method approved by the Director. The sensor shall be located as close as is practicable to the lowest portion of the sump.

  (e) Cathodic protection testing. Cathodic protection tests shall meet the inspection criteria outlined in 40 CFR 280.31(b), or other criteria approved by the Director. The tester who performs the test shall provide the following information: location of at least three test points per tank, location of one remote test point for galvanic systems, test results in volts or millivolts, pass/fail determination for each tank, line, flex connector, or other UST system component tested, the criteria by which the pass/fail determination is made, and a site plat showing locations of test points. A re-test of any cathodic protection system is required within six months of any below-grade work that may harm the integrity of the system.

  (f) UST testers performing tank and line tightness testing shall include the following as part of the test report: pass/fail determination for each tank or line tested, the measured leak rate, the test duration, the product level for tank tests, the pressure used for pressure tests, the type of test, and the test equipment used.
