1. What components are included in the definition of an 'Underground Storage
Tank'?: The Tank and all Connected Piping.
2. Which type of tank is considered an Underground Storage Tank?: Petroleum Storage
Tank.
3. What must the UST Owner or Operator demonstrate regarding financial
responsibility?: For Residential Tanks >1,100 gallons.
4. Which UST Systems meet the requirement for secondary containment?: Double
Walled Tanks.
5. What is a requirement for spill buckets?: They must be tested annually.
6. Which of the following is NOT an approved overfill protection system?: Spill
buckets.
7. Where must an overfill alarm be located?: So that it can be seen and/or heard from the delivery
location.
8. According to Title 23, which piping components must have secondary con-
tainment if installed after July 1, 1987?: Pressurized product piping.
9. What is true about impressed current cathodic protection systems?: None of the
above.
10. What is the minimum transfer amount that allows the Local Agency to waive
the requirement for overfill protection?: 25 gallons.
11. What components are considered 'pipe' on tanks installed after July 1, 2003?-
: Both pressurized product piping and below ground vapor recovery lines.
12. What requires independent third party certification to prove compliance?: Al
of the above (automatic tank gauging system, liquid product detectors, statistical inventory reconciliation methods).
13. What are acceptable test methods for ensuring tanks installed after July 1,
2003 are product tight?: All of the above (Enhanced Leak Detection, Inert Gas Pressure Test, Helium Test).
14. When is a one-time test required for tanks constructed after July 1, 2003?: If
the tank is located within 1,000 feet of a public drinking water well.
15. When was under-dispenser containment required for all systems installed?-
: After January 1, 2000.
16. What was the deadline for under-dispenser containment requirements for
all UST systems?: December 31, 2003

17. What must continuous monitoring methods for new UST systems be con-
nected to?: An alarm system approved by the Local Agency.
18. How often should an automatic tank gauge (ATG) be programmed to test the
tank?: At least monthly.
19. How frequently must tank integrity testing be accomplished when using
statistical inventory reconciliation?: Every 2 years.
20. What is an approved quantitative method of non-visual monitoring for exist-
ing UST systems?: Statistical Inventory Reconciliation.
21. What is the recommended pick-up line setting in a suction system tank?: 50%
level of tank.
22. In a coaxial phase I vapor recovery system, how many openings in the tank
are utilized?: 1
23. What is suggested for tanks in a siphon system?: Tanks be of the same diameter.
24. What is the minimum slope requirement for piping from dispensers to
containment?: 1/8 inch per foot.
25. What happens when a bladder system is installed in a UST hole?: Fuel is contained
while water penetrates the membrane into native soil.
26. Why are overfill containment buckets installed in concrete with a slope?: To
prevent water from entering.
27. Where should dispenser shear valves be installed according to NFPA?: At a
maximum of 6 inches above finish grade.
28. Who must approve the ordered equipment for UST systems?: Must be approved by
PEI.
29. When is it deemed safe to enter an excavation area according to OSHA?: When
air monitoring has been conducted.
30. Which factor does not affect cave-ins?: Relative humidity.
31. When may deadman be installed?: When excavation has a high water table and there is the
possibility of flooding.
32. Why is the use of pea gravel or crushed rock acceptable as back fill materi-
al?: Because it is self-leveling.
33. What should be the pressure and percentage for testing primary piping after
installing a secondary piping system?: 150% and 15 psi.
