Under 40 CFR Part 112, how long must a marina retain records of SPCC plan inspections and discharge events?

Answer: 3 years

40 CFR Part 112 requires that records of inspections, tests, drills, and discharge events related to the SPCC plan be retained for a minimum of three years.

In a Stage II vapor recovery system installed at a marina fuel dock, what specifically is being recovered?

Answer: Vapors displaced from the boat's fuel tank during the fueling process

Stage II vapor recovery captures the fuel vapors displaced from the customer's vessel fuel tank during fueling, as opposed to Stage I which captures vapors during bulk fuel delivery to the storage tank.

According to boating safety guidelines, before starting a marine engine after fueling, the bilge blower should be run for a minimum of how many minutes to clear fuel vapors?

Answer: 4 minutes

Running the bilge blower for at least 4 minutes after fueling is the standard safety recommendation to remove flammable fuel vapors from the bilge before engine ignition.

A marina with an aboveground storage tank of 10,000 gallons of gasoline experiences a 50-gallon spill that reaches the water. Which agency must be notified first?

Answer: National Response Center (NRC) at 1-800-424-8802

Any oil discharge to navigable waters must be immediately reported to the National Response Center, which is the federal point of contact for all pollution incident reporting under the Clean Water Act and OPA 90.

Ethanol-blended marine fuels (E10) create a specific storage challenge known as 'phase separation.' What does phase separation mean in this context?

Answer: Water absorbed by the ethanol separates from the gasoline, forming a water-ethanol layer at the bottom of the tank

Ethanol absorbs water vapor from the air, and when enough water accumulates, the ethanol and water mixture separates from the gasoline and sinks to the bottom, causing engine damage if ingested.

Which NFPA 303 requirement specifies how fuel dispensing hoses at a marina fuel dock must be managed when not in use?

Answer: Hoses must be properly stowed on approved reels or hooks to prevent damage and leaks

NFPA 303 requires that fuel dispensing hoses be properly stowed on approved reels or hooks when not in use to prevent physical damage, kinking, and accidental fuel leaks.

A marina operator wants to install a new aboveground fuel storage tank. Which of the following is a mandatory step under EPA and state regulations before installation?

Answer: Updating the SPCC plan and notifying the EPA regional office if the plan is amended

Adding a new aboveground storage tank that increases total storage capacity requires amending the SPCC plan; if the plan is amended, it must be reviewed and certified, and in some cases the EPA regional office must be notified.
