Section R311-203-5 - PST Testing Requirements(1) Tank tightness testing. The testing method must be able to test the PST system at the maximum level that could contain regulated substances. (a) 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.(2) 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) must report the test results using: (a) the form "Utah Spill Prevention Test"; or(b) 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(c) another form approved by the director.(3) 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 Section R311-206-11 must report the test results using: (a) the form "Utah Containment Sump Test"; or(b) the form "Appendix C-4 Containment Sump Integrity Testing Hydrostatic Testing Method," found in PEI RP1200; or(c) another form approved by the director.(4) When a sump sensor is used as an automatic line leak detector, the secondary containment sump must be tested for tightness annually according to the manufacturer's guidelines or standards, or by another method approved by the director. (a) the sensor shall be located as close as is practicable to the lowest portion of the sump.(5) Cathodic protection testing. Cathodic protection tests must meet the inspection criteria outlined in 40 CFR 280.31(b), or other criteria approved by the director. The tester who performs the test must provide the following information: (a) location of at least three test points per tank;(b) location of one remote test point for galvanic systems;(c) test results in volts or millivolts;(d) pass or fail determination for each tank, line, flex connector, or other UST system component tested;(e) the criteria by which the pass or fail determination is made;(f) a site plat showing locations of test points; and(g) 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.(6) UST testers performing tank and line tightness testing must include the following as part of the test report: (a) pass or fail determination for each tank or line tested;(d) product level for tank tests;(e) pressure used for pressure tests;(7) overfill prevention equipment inspection. An individual who conducts an inspection of overfill prevention equipment to meet the requirements of 40 CFR 280.35(a)(2) must report the results using:(a) the form "Appendix C-5 UST Overfill Equipment Inspection Automatic Shutoff Device and Ball Float Valve," found in PEI RP1200, when the overfill prevention is provided by either an automatic shutoff device or a ball float valve;(b) the form "Appendix C-6 Overfill Alarm Operation Inspection," found in PEI RP1200, when overfill prevention is provided by an overfill alarm; or(c) another form approved by the director.(8) Automatic tank gauge inspection. An individual who conducts an inspection of automatic tank gauges to meet the requirements of 40 CFR 280.40(a)(3) must report the results using:(a) the form "Appendix C-7 Automatic Tank Gauge Operation Inspection," found in PEI RP1200, and if the PST system or any portion thereof is interstitially monitored, "Appendix C-8: Liquid Sensor Functionality Testing," found in PEI RP1200; or(b) another form approved by the director.(9) Automatic line leak detector testing. An individual who conducts a test of automatic line leak detectors to meet the requirements of 40 CFR 280.40(a)(3) must report the results using:(a) the form "Appendix C-9 Mechanical and Electronic Line Leak Detector Performance Tests," found in PEI RP1200; or(b) another form approved by the director.(10) Leak Detection and Testing Requirements for APSTs:(a) line tightness testing or monthly monitoring is required for underground piping associated with APSTs. (i) an individual who conducts a tightness test of product lines must perform the test as set forth in 40 CFR 280.44(b).(ii) when pressurized underground product piping is connected to an APST that is not double-walled, sensor equipped, and monitored monthly, the product piping must be tested for tightness annually. The test must meet the requirements of Subsection R311-203-5(6).(b) spill prevention equipment associated with an APST must meet the standards set forth in International Fire Code (IFC) 2306.6.2.6 referenced in the Utah State Fire Code adopted pursuant to Section 15A-5-103.(c) beginning July 1, 2026, an APST resting on the ground must perform monthly interstitial monitoring, a monthly 0.2 gallon per hour release detection test, or a tank tightness test every 5 years. The test must meet the requirements of Subsection R311-203-5(1).(d) beginning July 1, 2026, if applicable, APSTs and associated piping are required to have cathodic protection that meets the standards set forth in IFC 5704.2.7.9 and National Fire Protection Agency (NFPA) 30.23.3.5 and must have a passing cathodic protection test every 3 years. The test must meet the requirements of Subsection R311-203-5(5).(e) beginning July 1, 2026, an APST shall have an overfill prevention device that meets the standards set forth in IFC 2306.6.2.3, 5704.2.7.5.8 and 5704.2.927.5 and must have an overfill prevention equipment inspection performed every three years. The overfill prevention equipment inspection must meet the requirements of Subsection R311-203-5(7).(f) beginning July 1, 2026, an APST with pressurized underground product piping shall have an automatic line leak detector that meets the standards set forth in IFC 2306.7.7.1 and must have an automatic line leak detector test performed annually. The test must meet the requirements of Subsection R311-203-5(9).Utah Admin. Code R311-203-5
