What this exam covers
5 real sample questions
What is the aggregate aboveground oil storage capacity threshold, under 40 CFR 112.1(b), above which a facility may be subject to the SPCC rule (assuming the discharge-to-navigable-waters test is also met)?
A. >1,320 U.S. gallons
B. >660 U.S. gallons
C. >2,500 U.S. gallons
D. >5,000 U.S. gallons
Show answer and reasoning

Correct answer: A. >1,320 U.S. gallons

  • B: 660 gallons is the single-container reportable spill threshold used in the qualified-facility discharge history test, not the facility applicability threshold.
  • C: 2,500 gallons is not a threshold used anywhere in Part 112.
  • D: 5,000 gallons is the Tier I individual-container size limit under 112.6(a), not the applicability threshold.
Source: 40 CFR 112.1
Under 40 CFR 112.1(b), what completely buried oil storage capacity triggers potential SPCC applicability?
A. >42,000 U.S. gallons
B. >1,320 U.S. gallons
C. >21,000 U.S. gallons
D. >100,000 U.S. gallons
Show answer and reasoning

Correct answer: A. >42,000 U.S. gallons

  • B: 1,320 gallons is the aboveground aggregate threshold, not the buried-tank threshold.
  • C: 21,000 gallons is half the real threshold and appears nowhere in the rule.
  • D: 100,000 gallons is not a Part 112 threshold.
Source: 40 CFR 112.1
Under 40 CFR 112.1(d)(5), containers below what capacity are excluded from the aggregate storage capacity calculation used to determine SPCC applicability?
A. 55 U.S. gallons
B. 110 U.S. gallons
C. 275 U.S. gallons
D. 1,320 U.S. gallons
Show answer and reasoning

Correct answer: A. 55 U.S. gallons

  • B: 110 gallons is not the exclusion size in 112.1(d)(5).
  • C: 275 gallons is a common heating-oil tank size, not the regulatory exclusion threshold.
  • D: 1,320 gallons is the facility-level applicability threshold, not the individual container exclusion size.
Source: 40 CFR 112.1(d)(5)
For SPCC applicability determinations under 40 CFR 112.1, aggregate storage capacity is based on:
A. The shell (nameplate) capacity of each regulated container, regardless of how much oil is actually on hand
B. The average daily oil inventory over the prior calendar year
C. The maximum oil volume ever recorded in EPA inspection records
D. The container capacity after subtracting any permanently installed dike volume
Show answer and reasoning

Correct answer: A. The shell (nameplate) capacity of each regulated container, regardless of how much oil is actually on hand

  • B: Actual inventory levels are irrelevant; the rule counts shell capacity so a facility cannot avoid applicability by keeping tanks partially full.
  • C: EPA inspection history has no bearing on how capacity is calculated.
  • D: Dike volume is a secondary-containment sizing concept under 112.8(c)(2), not a factor in counting storage capacity.
Source: 40 CFR 112.1(b)
A facility's oil storage capacity exceeds the aggregate aboveground threshold in 40 CFR 112.1(b). What second condition must also be met for the facility to be subject to the SPCC rule?
A. Due to its location, the facility could reasonably be expected to discharge oil in harmful quantities into or upon navigable waters or adjoining shorelines
B. The facility must be inspected by EPA within the same calendar year
C. The facility must have received a Notice of Violation under the Clean Water Act
D. The facility must be located within 500 feet of a state-designated wetland
Show answer and reasoning

Correct answer: A. Due to its location, the facility could reasonably be expected to discharge oil in harmful quantities into or upon navigable waters or adjoining shorelines

  • B: EPA inspection is not a precondition for applicability; SPCC applicability is self-determined by the owner/operator.
  • C: A prior NOV is not part of the applicability test; many regulated facilities have never been cited.
  • D: 500 feet is not a distance test used anywhere in 40 CFR 112.1; the standard is a reasonable-expectation-of-discharge test, not a fixed buffer distance.
