(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

280.31(b), or other criteria
approved by the director. The tester who performs the test must provide the

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;
(b) measured leak
rate;
(c) test duration;
(d) product level for tank tests;
(e) pressure used for pressure
tests;
(f) type of test;
and
(g) test equipment
used.
(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
