Boating Certification Test Environmental Protection & Regulations 3 ā Questions and Answers
Question 1: What is the maximum allowable oil concentration in bilge water that may be discharged overboard in U.S. navigable waters?
- 15 parts per million (ppm)
- 25 ppm
- 100 ppm
- No oil-contaminated bilge water may be discharged (Correct answer)
Correct answer: No oil-contaminated bilge water may be discharged
In U.S. inland and coastal waters (within 3 nm), discharge of any oil-contaminated bilge water that causes a visible sheen is prohibited.
Question 2: The 'Clean, Drain, Dry' practice for boats and trailers is intended to prevent:
- Hull corrosion
- Spread of aquatic invasive species (Correct answer)
- Fuel contamination
- Propeller damage
Correct answer: Spread of aquatic invasive species
Clean, Drain, Dry removes aquatic hitchhikersāplants, animals, and pathogensāthat can invade and devastate new water bodies.
Question 3: Under MARPOL Annex V, which of the following items may NEVER be discharged into any waters from a recreational vessel?
- Food waste beyond 12 nm
- Plastics of any kind (Correct answer)
- Unground food scraps beyond 3 nm
- Cardboard packaging beyond 25 nm
Correct answer: Plastics of any kind
MARPOL Annex V strictly prohibits the discharge of all plastics into any waters, regardless of distance from shore.
Question 4: A marina posts a 'No Wake Zone' sign near a protected seagrass bed. The primary environmental reason for this restriction is:
- To prevent noise pollution for nearby residents
- To protect submerged aquatic vegetation from propeller scarring and wave turbulence (Correct answer)
- To reduce fuel consumption in the marina
- To comply with fishing regulations
Correct answer: To protect submerged aquatic vegetation from propeller scarring and wave turbulence
Prop wash and wave turbulence in shallow areas destroy seagrass beds, which are critical fish nursery habitats protected under various environmental laws.
Question 5: Which law requires boaters to report oil spills that cause a visible sheen on water to the National Response Center?
- The Rivers and Harbors Act
- The Clean Water Act / Oil Pollution Act (Correct answer)
- The Marine Mammal Protection Act
- The Endangered Species Act
Correct answer: The Clean Water Act / Oil Pollution Act
The Clean Water Act and Oil Pollution Act together require immediate reporting of any oil discharge causing a visible sheen to the NRC at 1-800-424-8802.
Question 6: What is the primary purpose of a marine pumpout station at a marina?
- To refuel vessels with clean diesel
- To remove sewage from onboard holding tanks for proper disposal (Correct answer)
- To pump bilge water from flooded vessels
- To provide fresh water for boat washing
Correct answer: To remove sewage from onboard holding tanks for proper disposal
Marine pumpout stations remove accumulated sewage from Type III holding tanks so it can be properly treated at a land-based facility.
Question 7: An operator spots a sea turtle swimming near the boat. Under the Endangered Species Act, what is required?
- The operator must immediately call the Coast Guard
- The operator must maintain a safe distance and avoid disturbing the animal (Correct answer)
- The operator may continue at any speed as long as they do not hit it
- Sea turtles are not protected in federal waters
Correct answer: The operator must maintain a safe distance and avoid disturbing the animal
The Endangered Species Act protects sea turtles; operators must avoid disturbing, harassing, or injuring them and maintain safe distances.
