Online Boating Environmental Responsibility & Conservation Flashcards

What is the correct procedure when a fuel spill occurs during boat fueling?

Answer: Absorb the spill immediately with absorbent pads, contain it, and report significant spills to the Coast Guard

Absorbent pads should be used immediately to contain fuel spills; federal law requires reporting spills that cause a sheen on the water to the National Response Center.

Which statement about wildlife watching from a boat is correct?

Answer: Maintaining a safe distance and avoiding sudden movements minimizes stress to marine wildlife

Keeping respectful distances, moving slowly, and avoiding loud noises prevents stress responses, disruption of feeding, and separation of mothers from young.

What is the purpose of a Marine Sanitation Device (MSD) Type I?

Answer: It treats sewage to reduce bacteria levels below a legal threshold before discharge

A Type I MSD treats sewage to meet federal coliform bacteria standards before it is discharged, making it legal to use in many waters outside No Discharge Zones.

How does boat engine exhaust contribute to water quality problems?

Answer: Hydrocarbons and nitrogen oxides from two-stroke engines dissolve in water and harm aquatic organisms

Older two-stroke engines discharge partially burned fuel directly into the water, introducing toxic hydrocarbons that harm fish, invertebrates, and algae.

What should a boater do if they observe someone else illegally dumping garbage overboard?

Answer: Note the vessel description and registration number and report to the Coast Guard or environmental authorities

Recording the vessel's details and reporting to the Coast Guard or state environmental agency gives authorities the information needed to investigate and enforce marine pollution laws.

Which practice most effectively reduces underwater noise pollution that affects marine mammals?

Answer: Slowing vessel speed and reducing unnecessary engine idling near known marine mammal habitats

Slowing down reduces propeller cavitation noise and engine vibration, significantly lowering the acoustic footprint in habitats where whales and dolphins rely on sound for communication.

What is the recommended action when boating near nesting shorebirds on a beach or island?

Answer: Maintain at least 150-300 feet distance and do not land or anchor near nesting colonies

Approaching nesting colonies causes adults to flush, exposing eggs and chicks to sun, predators, and trampling; guidelines recommend staying 150-300+ feet away during nesting season.
