It's the Law: The Environment and Your Vessel

Includes: Discharge of Sewage and Waste, Discharge of Oil and Hazardous Substances, Discharge of Trash, and Waste Management Plan

As a boater, it's your legal responsibility to help protect Washington's aquatic environment.

Discharge of Sewage and Waste

  • Sewage discharged from vessels can pose environmental problems, especially in shallow bays and inlets.
  • It is important that you treat or dispose of your sewage properly. If you have a vessel with installed toilet facilities, it must have an operable marine sanitation device (MSD) on board and be designed to prevent discharge into the water. If your vessel does not have installed toilet facilities, consider carrying a portable toilet.
  • All installed MSDs must be U.S. Coast Guard–certified.
  • If you have treated sewage, flush in deep water and avoid flushing in small bays, in marinas, or near shellfish beds.
  • Use pump-out stations. Click here to see pump-out location maps or call 360-902-8844.

Types of MSDs

Types I and II MSDs treat waste with special chemicals to kill bacteria. When in waters where sewage cannot be dumped overboard (for example, any freshwater body of water), these MSDs must have the “Y” valve secured so that it cannot be opened. This can be done by placing a lock or non-reusable seal on the “Y” valve or by taking the handle off the “Y” valve in a closed position.

Type III MSDs provide no treatment and are either holding tanks or portable toilets. Collected waste should be taken ashore and disposed of in a pump-out station or onshore toilet.

Discharge of Oil and Other Hazardous Substances

  • It is illegal to discharge oil or hazardous substances, or anything else, into state or federally controlled waters.
  • Using soap as a dispersant on an oil spill is illegal, and a violator may be fined up to $10,000 per day by the state. Federal fines also may be given.
  • You are not allowed to dump oil into the bilge of the vessel without means for proper disposal.
  • You must dispose of oil waste at an approved reception facility. On recreational vessels, a bucket or bailer is adequate for temporary storage prior to disposing of the oil waste at an approved facility.
  • On federally controlled waters, vessels 26 feet or longer must display a 5 x 8-inch placard near the machinery space or at the bilge pump switch, stating the Federal Water Pollution Control Act.

Hazardous Substances and the Boater

No paint or varnish product is environmentally safe, and all are toxic to both humans and marine life. When cleaning or painting your vessel, it’s important to protect the water.

  • Minimize your use of toxic materials while the vessel is in the water. Use biodegradable and low-phosphate products whenever possible.
  • Use an absorbent sponge in your bilge to soak up oil. Have oil absorbent pads or rags on hand in case of a spill. When changing engine oil, wipe up any spills so that the oil isn’t pumped overboard with the bilge water.
  • Use a suspended tarp to catch spills, paint scrapings, or debris that would end up in the water.
  • Inspect your fuel lines periodically. Replace bad ones with USCG–approved Type A alcohol-resistant, fuel line hoses.
  • Dispose of old antifreeze and oil on shore in a recycling container.
  • Antifouling paint is used to prevent the growth of organisms on vessel bottoms. Some antifouling paints use tributyltin, which has been found to cause abnormal development and reduced reproduction in marine life. Instead, use a “non-fouling” paint (silicon-or teflon-based) or non-abative (copper-based) antifouling paint.

Discharge of Trash

It is illegal to dump refuse, garbage, or plastics into state or federally controlled waters.

You must store trash in a container on board, and place it in a proper receptacle after returning to shore.

You must display, in a prominent location, a durable placard (sign) at least 4 x 9 inches on any vessel 26 ft. or longer. It must notify passengers and crew about discharge restrictions of the Marine Pollution Act (MARPOL).

Obtain a placard from a marine supply store or from the:

National Oceanic and Atmospheric Administration
Marine Debris Information Office

1725 De Sales Street
N.W., Suite 500
Washington, DC 20036

Marine Pollution Act (MARPOL) placard

To help keep our waters clean:

  • Carry a trash container on your vessel and empty it into a trash receptacle on shore.
  • Make sure no trash or plastics are discarded overboard.

Waste Management Plan

Federal law requires ocean-going vessels of 40 feet or longer with a galley and berth to have a written Waste Management Plan. The captain of the vessel is responsible for implementing the Waste Management Plan. The Waste Management Plan, identifying the vessel’s name and home port, should be posted and should include directives to all persons on board about:

  • Discharging of sewage and hazardous substances
  • Discharging of garbage and other food waste
  • Disposing of plastics, bottles, and cans
  • Reading applicable placards for additional information
  • Advising the captain in case of oily discharges or diesel spills
