SECTION 1: UST Regulations & Compliance Overview (Q1-Q25)
Q1: Under N.J.A.C. 7:14B, which federal regulation do New Jersey's UST rules
incorporate by reference for technical standards on UST system design and operation?
A. 40 CFR Part 261
B. 40 CFR Part 280 [CORRECT]
C. 40 CFR Part 302
D. 40 CFR Part 112
Correct Answer: B
Rationale: N.J.A.C. 7:14B incorporates 40 CFR Part 280 by reference for federal UST
technical standards. Part 261 covers hazardous waste identification, Part 302 covers
emergency planning, and Part 112 covers SPCC plans for aboveground storage.
Q2: A facility in New Jersey has three regulated USTs containing gasoline. According to
NJDEP requirements, how many Class A operators must be designated at minimum?
A. One per tank
B. One for the entire facility [CORRECT]
C. One per shift
D. No designation required if the owner is on-site
Correct Answer: B
Rationale: N.J.A.C. 7:14B-5.14 requires at least one designated Class A operator per
UST facility, not per tank. The Class A operator holds overall responsibility for
compliance and safe operation of the entire UST system.
Q3: Which of the following tank types is EXEMPT from regulated UST requirements
under N.J.A.C. 7:14B?
A. A 1,500-gallon diesel UST at a retail gas station
B. A 550-gallon residential heating oil UST [CORRECT]
C. A 2,000-gallon gasoline UST at a municipal fleet facility
,D. A 1,000-gallon waste oil UST at an auto repair shop
Correct Answer: B
Rationale: Under N.J.A.C. 7:14B and 40 CFR 280.12, USTs containing heating oil for
consumptive use on the premises where stored (including residential) are exempt from
regulated UST requirements. All other options describe regulated petroleum USTs.
Q4: A new UST system is being installed in New Jersey. Under current regulations, what
is the minimum required secondary containment for new USTs?
A. Single-walled construction with leak detection only
B. Double-walled tanks and piping with interstitial monitoring [CORRECT]
C. Single-walled tanks with cathodic protection only
D. Concrete vaults without interstitial monitoring
Correct Answer: B
Rationale: Both federal 40 CFR 280.20 and NJDEP rules require new UST systems to
have secondary containment (double-walled tanks and piping) with interstitial
monitoring. Single-walled systems are prohibited for new installations.
Q5: A gas station owner in New Jersey has failed to designate a Class B operator for 45
days. What is the NJDEP's most likely enforcement action?
A. Immediate facility shutdown
B. Notice of violation requiring designation within 30 days [CORRECT]
C. $1 million fine assessed immediately
D. No action required until the next inspection
Correct Answer: B
Rationale: N.J.A.C. 7:14B-5.14 requires designated operators at all times. NJDEP
typically issues a Notice of Violation (NOV) for operator designation failures, allowing
corrective action within 30 days. Immediate shutdowns are reserved for imminent
threats.
Q6: Under 40 CFR Part 280, a UST containing which substance would be regulated as a
hazardous substance UST rather than a petroleum UST?
A. Kerosene
B. Pure ethanol stored for fuel blending
C. Diesel fuel
D. Gasoline containing 10% ethanol (E10)
,Correct Answer: B
Rationale: 40 CFR 280.12 defines petroleum USTs as containing petroleum-based
substances. Pure ethanol is not petroleum-based and would be regulated under
hazardous substance UST provisions if listed under CERCLA. Kerosene, diesel, and E10
are all petroleum-based fuels.
Q7: A facility has a 2,000-gallon UST that has been out of service for 3 years. Under
NJDEP rules, what must the owner do?
A. Continue monthly release detection indefinitely
B. Permanently close the UST within 12 months of permanent closure determination
[CORRECT]
C. Remove all product and leave the tank in place
D. Convert it to an aboveground tank without permits
Correct Answer: B
Rationale: N.J.A.C. 7:14B requires USTs out of service for more than 12 months to be
permanently closed. Temporary closure requirements include maintaining corrosion
protection and release detection for up to 12 months. After that, permanent closure
(removal or closure-in-place with NJDEP approval) is required.
Q8: Which agency is responsible for administering the Class A/B operator certification
exam in New Jersey?
A. NJDEP directly
B. International Code Council (ICC) [CORRECT]
C. Rutgers University
D. New Jersey State Police
Correct Answer: B
Rationale: While Rutgers provides the required training course, the actual certification
exam is administered by the International Code Council (ICC). NJDEP sets the
regulatory framework but contracts with ICC for examination services.
Q9: A UST owner discovers a 15-gallon release from a dispenser hose. Under NJDEP
rules, within what timeframe must this be reported to NJDEP if it enters the
environment?
A. Within 24 hours
B. Within 2 hours
, C. Immediately upon discovery [CORRECT]
D. Within 7 days
Correct Answer: C
Rationale: N.J.A.C. 7:14B and the Spill Act (N.J.S.A. 58:10-23.11) require immediate
reporting of any discharge to the environment. Any release that enters soil, groundwater,
or surface water must be reported to NJDEP immediately, regardless of quantity.
Q10: Under N.J.A.C. 7:14B, what is the maximum capacity for a UST to be considered
"small" and subject to certain reduced requirements?
A. 550 gallons
B. 1,100 gallons [CORRECT]
C. 2,000 gallons
D. 5,000 gallons
Correct Answer: B
Rationale: 40 CFR 280.12 and NJDEP rules define a small UST as one with a capacity of
1,100 gallons or less. However, note that small USTs are still regulated USTs and must
meet most requirements, though some provisions differ.
Q11: A facility operator is confused about whether a tank containing 1,000 gallons of
used oil is regulated under UST rules. What is the correct determination?
A. All used oil USTs are completely exempt
B. Used oil USTs are regulated if connected to a heating system
C. Used oil USTs are regulated USTs unless they are solely for on-site heating oil
consumption [CORRECT]
D. Used oil USTs are only regulated if above 10,000 gallons
Correct Answer: C
Rationale: Used oil USTs are regulated under N.J.A.C. 7:14B and 40 CFR 280 unless they
qualify for the heating oil exemption (consumptive on-site use). The used oil must meet
the definition of petroleum to be regulated.
Q12: Which of the following is a violation of NJDEP UST financial responsibility
requirements?
A. Maintaining $1 million per occurrence coverage for a facility with 10 USTs
B. Using a self-insurance mechanism approved by NJDEP
C. Allowing pollution liability insurance to lapse for 30 days [CORRECT]
D. Maintaining $500,000 annual aggregate coverage for a facility with 3 USTs
