CHAPTER 4: The Marine Environment
4.1 ENVIRONMENTAL LAWS AND REGULATIONS
4.1.1 SUBMERSED AQUATIC VEGETATION (SAV)
Submersed aquatic vegetation (or SAV) consists of underwater plants
often found in shallow areas (usually less than 6 feet deep). They are
important habitat for fish and shellfish, and are a food source for
several waterfowl species. Scientific studies have shown that SAV
beds can be scarred by boat propellers or by larger craft if they run a
ground. When operating your boat in shallow areas, be careful to avoid
damaging SAV. Do not operate a personal watercraft in such areas.
4.1.2 AQUATIC NUISSANCE SPECIES
Non-native aquatic species (plants, fish and
animals) are found within Oregon's waters.
These pests can increase dramatically under
the right conditions, displacing native species,
clogging waterways, and impacting navigation
and recreation. Once introduced, they are
nearly impossible to eliminate. Zebra and Quagga Mussels
are nuisance species that can be accidentally
transported by recreational boaters when caught
in propellers, intakes or attached to hulls.
YOU CAN HELP PREVENT THE INTRODUCTION AND SPREAD OF NON-NATIVE SPECIES FROM ONE BODY OF WATER TO ANOTHER.
Once on shore, away from the water:
- Inspect your boat and remove aquatic plants or animals before you leave any body of water.
- Flush raw-water cooling systems and clean sea strainers before moving your boat from one body of water to another.
- Empty bait buckets and remove any plant fragments from bait wells, fishing gear, trailers, dive gear or props. Dispose of the plant fragments on land, in a garbage receptacle.
- Drain water from your motor, live wells and bilge.
- Wash your boat before putting it into a new body of water
- Report sightings of non-native species to 1-866-INVADER or call 1-800-437-2744, 24 hours 7 days a week.
TO STOP THE SPREAD OF AQUATIC SPECIES, IT IS BEST TO CLEAN YOUR BOAT BEFORE YOU LEAVE THE BODY OF WATER.
4.1.3 ADDITIONAL ENVIRONMENTAL CONSIDERATIONS
Be cautious and use spill prevention pads when refueling your vessel in or near the water. Gas or oil spills can have significant negative effects on the environment. Respect the wildlife and never use your vessel in a manner to harass the local wildlife. Reduce speed to "no wake" speed when approaching shorelines or in narrow channels, thus reducing possible erosion from a larger wake.
4.1.4 GARBAGE DISPOSAL
| The U.S. Coast Guard prohibits dumping of plastic or garbage mixed with plastic in any waters. |
|
DISTANCE FROM SHORE:
|
IT IS ILLEGAL TO DUMP:
|
| Inside 3 miles and in U.S. lakes,
rivers, bays and sounds and
anywhere on the Great Lakes,
no matter how far from shore
|
Plastic, dunnage, lining, and
packing materials that float,
and any garbage except
dishwater/ gray water/ fresh
fish parts
|
| 3 to 12 miles |
Plastic, dunnage, lining, and
packing materials that float,
and any garbage not ground
to less than one square inch
|
| 12 to 25 miles |
Plastic, dunnage, lining, and
packing materials that float
|
| Outside 25 miles |
Plastic
|
| Note: Dunnage refers to packing materials such as foam or pellets. |
Additionally, vessels greater than
26 feet in length and operating in
federal waters must display a
4x8-inch SOS (Save our Seas)
placard in a conspicuous place
that outlines waste disposal
regulations. Placards can be
purchased from most boat
dealers and marinas.
UNTREATED HUMAN WASTE MAY NEVER
BE DUMPED IN INLAND WATERS. HELP KEEP OUR WATER CLEAN AND BEAUTIFUL.
4.1.4.1 LITTERING IN OREGON
Littering in Oregon waters is strictly prohibited. Offenders can face stiff penalties for littering, including suspension of the Certificate of Number (Registration) and fines.
4.1.5 WASTE LIQUIDS
You may dump raw sewage
ONLY when you are more
than three nautical miles
from shore on the ocean.
Some states, and Canada,
also have regulations for
the dumping of gray water
(dishwater, shower water,
laundry water) and treated
waste. Consult your local
authorities to find out the
local laws.
4.1.6 WASTE MANAGEMENT PLANS
Any vessel longer than 40 feet, with
a berth and a galley, and certified to
operate beyond three nautical miles
from shore MUST have a written
Waste Management Plan. The Waste
Management Plan must be written
and implemented by the boat captain.
A Waste Management Plan should
provide directions to passengers and
crew as to the procedure for dealing
with the discharge of the following:
- Sewage and hazardous waste
- Garbage and food waste
- Plastics, glass and aluminum
- Oily discharges and gasoline spills
4.2 HUMAN WASTE DISPOSAL
4.2.1 MARINE SANITATION DEVICE (MSD)
Boats operating inland with an installed toilet must also have a
sanitation system to prevent pollution and discharge of raw sewage.
A typical sanitation system consists of an installed toilet, a waste
treatment system, and/or a holding tank. Be sure to check your
MSD for U.S. Coast Guard Certification.

Figure 1: Pump-out station sign
Pump-out Signs are displayed at marinas
with Pump-Out facilities throughout the
United States (Figure 1 is a sample of a
Pump-Out Sign). Check with local marinas
to locate convenient Pump-Out Stations
prior to your voyage.
4.2.2 OREGON MSD REGULATIONS
The discharge of any sewage from marine toilets is prohibited on Oregon's freshwater lakes, impoundments, and reservoirs that are not accessible by boat from the ocean. Type I and II MSDs can only be discharged in Federal Navigable waterways.
The use of approved types of marine sanitation devices (MSDs) is required on the Columbia, Willamette, and Snake Rivers and on the navigable portions of all coastal rivers. Discharge of untreated sewage is only permitted beyond the three mile ocean limit.
4.3 DISPOSAL OF TOXIC SUBSTANCES
The Refuse Act of 1899 prohibits throwing, discharging or depositing
of any refuse matter of any kind into United States waters.
Refuse includes Garbage, trash, oil and other liquid pollutants.
Vessels greater than 26 feet and operating in federal waters must
display a 5x8–inch placard in a clearly visible place that states
the following:
Therefore, boat operators are not allowed to dump oil into the bilge
of their boat without means for proper disposal. Oil must be kept on
board in a receptacle until it can be properly disposed of. If oil is
discharged accidentally, call 800-424-8802 to report the accident
to the Coast Guard.
