Alabama Boaters Environmental Protection & Responsibility 3 â Questions and Answers
Question 1: What does the term 'No Discharge Zone' (NDZ) mean for boaters?
- All overboard discharge of sewageâtreated or untreatedâis prohibited (Correct answer)
- Only raw sewage discharge is prohibited; treated discharge is allowed
- The zone applies only to commercial vessels
- Discharge of gray water (sink/shower) is also prohibited in all cases
Correct answer: All overboard discharge of sewageâtreated or untreatedâis prohibited
In an EPA-designated No Discharge Zone, no sewage of any kindâregardless of treatment levelâmay be discharged overboard.
Question 2: How does excessive boat wake damage riparian (shoreline) environments?
- It causes bank erosion, uproots aquatic plants, and disturbs nesting birds (Correct answer)
- It aerates the water and promotes fish growth
- It only affects artificial structures, not natural banks
- Wake damage is negligible at speeds under 30 mph
Correct answer: It causes bank erosion, uproots aquatic plants, and disturbs nesting birds
Repeated wave action from boat wakes erodes natural shorelines, destroys submerged aquatic vegetation, and disturbs nesting wildlife.
Question 3: What is the correct way to dispose of used engine oil after an oil change on a boat?
- Take it to a marina recycling center or automotive shop that accepts used oil (Correct answer)
- Dilute it with water and discharge it overboard slowly
- Burn it off by running the engine at high RPM
- Bury it on shore away from the water's edge
Correct answer: Take it to a marina recycling center or automotive shop that accepts used oil
Used motor oil must be recycled at an approved facility; a single quart can contaminate 250,000 gallons of drinking water.
Question 4: Which invasive species has most significantly impacted Alabama freshwater lakes and rivers through boat transport?
- Hydrilla and other aquatic invasive plants transported on boats and trailers (Correct answer)
- Largemouth bass introduced from neighboring states
- Native catfish populations spreading between watersheds
- Blue herons relocating to new fishing areas
Correct answer: Hydrilla and other aquatic invasive plants transported on boats and trailers
Invasive aquatic plants like hydrilla clog waterways and are commonly spread by boats and trailers that aren't cleaned between launches.
Question 5: What does 'Clean, Drain, and Dry' refer to in Alabama boating regulations?
- A required practice to prevent transporting invasive species between water bodies (Correct answer)
- A maintenance routine for boat engines before winter storage
- The procedure for cleaning a marine MSD holding tank
- A Coast Guard inspection checklist for bilge cleanliness
Correct answer: A required practice to prevent transporting invasive species between water bodies
Clean, Drain, and Dry is the recommended decontamination protocol for boats, trailers, and gear to stop invasive species spread.
Question 6: What federal act primarily governs the discharge of oil and hazardous substances from vessels into US waters?
- The Clean Water Act (Correct answer)
- The National Marine Sanctuaries Act
- The Endangered Species Act
- The Marine Mammal Protection Act
Correct answer: The Clean Water Act
The Clean Water Act (CWA) prohibits discharge of oil or hazardous substances into US waters in quantities that may be harmful.
Question 7: Why should boaters avoid anchoring in seagrass beds in Alabama's coastal waters?
- Anchors and chains destroy seagrass, which provides critical habitat for juvenile fish and sea turtles (Correct answer)
- Seagrass can foul an anchor making it hard to retrieve
- Anchoring in seagrass provides less holding power than sandy bottoms
- Seagrass beds are breeding grounds for invasive jellyfish
Correct answer: Anchors and chains destroy seagrass, which provides critical habitat for juvenile fish and sea turtles
Seagrass meadows are essential nursery habitats for commercially important fish species, and anchor damage is slow to recover.
