CMM Fuel Management & Petroleum Operations 2 — Questions and Answers
Question 1: Under the Clean Water Act, any oil discharge to navigable waters that creates what condition must be immediately reported to the National Response Center?
- A discharge exceeding 100 gallons
- A visible sheen on the water surface (Correct answer)
- A discharge detectable by smell alone
- A discharge exceeding 10 gallons
Correct answer: A visible sheen on the water surface
The Clean Water Act requires reporting any oil discharge that causes a visible sheen on the water, regardless of volume, because even small amounts can harm aquatic ecosystems.
Question 2: What is the minimum total aboveground oil storage capacity at a marina that triggers the requirement to develop an SPCC Plan under 40 CFR Part 112?
- 660 gallons
- 1,320 gallons (Correct answer)
- 5,000 gallons
- 10,000 gallons
Correct answer: 1,320 gallons
Facilities with a total aboveground oil storage capacity greater than 1,320 gallons are subject to SPCC plan requirements under 40 CFR Part 112.
Question 3: When responding to a fuel spill at the fuel dock, what is the FIRST action a marina employee should take?
- Notify the harbor master and local authorities
- Deploy absorbent booms to contain the spread
- Stop or minimize the source of the spill (Correct answer)
- Document the incident and photograph the scene
Correct answer: Stop or minimize the source of the spill
Stopping the spill source is always the first priority because containing and cleaning up a spill is far more effective when the flow of fuel has been halted.
Question 4: A marina manager discovers that the diesel fuel in storage has been contaminated with water. What is the correct initial response?
- Continue selling the fuel at a discounted price to minimize losses
- Add a fuel stabilizer product to absorb the water contamination
- Remove the fuel from service and test the tank for the extent of contamination (Correct answer)
- Dilute the contaminated fuel with fresh uncontaminated diesel
Correct answer: Remove the fuel from service and test the tank for the extent of contamination
Contaminated fuel must be immediately taken out of service to prevent engine damage to customers' vessels; the tank must then be tested and the contamination source identified.
Question 5: What is 'vapor recovery' in marina fuel dock operations, and why is it important?
- Reclaiming spilled fuel from the water surface to reduce environmental impact
- Capturing fuel vapors displaced during fueling to reduce air pollution and fire risk (Correct answer)
- Removing water vapor from fuel tanks to improve fuel quality
- Measuring tank vapor pressure to calculate fuel inventory
Correct answer: Capturing fuel vapors displaced during fueling to reduce air pollution and fire risk
Vapor recovery systems capture hydrocarbon vapors that would otherwise be released into the atmosphere during fueling, reducing both air pollution and the risk of vapor ignition.
Question 6: Which standard water-contamination test is commonly used by marina fuel technicians to check diesel fuel for water infiltration?
- Litmus pH test strip
- Water-finding paste applied to a measuring stick (Correct answer)
- Specific gravity hydrometer test
- Flash point temperature test
Correct answer: Water-finding paste applied to a measuring stick
Water-finding paste (such as Kolor Kut) changes color when it contacts water, making it a quick and reliable field method for detecting water at the bottom of fuel tanks.
Question 7: What type of insurance coverage is specifically designed to protect a marina from financial liability arising from petroleum spills and environmental cleanup costs?
- General commercial liability insurance
- Workers' compensation insurance
- Pollution liability insurance (Correct answer)
- Marine property and casualty insurance
Correct answer: Pollution liability insurance
Pollution liability insurance specifically covers costs associated with petroleum spills, environmental cleanup, third-party property damage, and regulatory fines that general liability policies typically exclude.
