2. Spill-proof your oil changes
For oil changes, use an oil change pump to transfer oil to a spill proof container. Wrap a plastic bag or absorbent pad around the oil filter to prevent oil from spilling into the bilge.

3. Spill-proof your fueling practices
Prevent fuel spills by filling fuel tanks slowly and carefully and by using absorbent pads or rags to catch drips and spills. Don't "top off" or overflow your fuel tank and leave 5% empty to allow fuel to expand as it warms.

4. Do not add soap
Never use soap to disperse fuel and oil spills. It increases harm to the environment, and it is illegal.

5. Minimize boat cleaning and maintenance in the water.
If possible, save maintenance projects for the boatyard. When performing work on the water minimize your impact by containing waste using tarps and vacuum sanders, and collect all drips and debris for proper disposal.

6. Reduce toxic discharges from bottom paints
Minimize the discharge of heavy metals that come from soft-sloughing antifouling paints by using a hard, less toxic, or nontoxic antifouling paint. Use only non-abrasive underwater hull cleaning techniques to prevent excessive paint discharge. Remember, dry storage and reduces the need for antifouling paints and saves money.

7. Dispose of hazardous waste properly
Dispose of paints, batteries, antifreeze, cleaning products, oil, oil filters and other hazardous wastes at a hazardous waste collection facility or event. Call 1-800-CLEAN-UP for a location near you. Recycle paints, batteries, oil, oil filters and antifreeze.

8. Plan A-head! Manage sewage wastes properly
Never discharge sewage within 3 miles of shore. Use harbor pump-out stations and shore-side facilities. If you don't have an installed toilet, use a port-a-potty and empty it at harbor dump station or bathroom.

9. Stow it, do not throw it!
Keep your trash on board. Never throw cigarette butts, fishing line, or any other garbage into the ocean. Take advantage of shore-side facilities to recycle plastic, glass, metal, and paper.

10. Reduce gray-water discharges
Use a phosphate-free soap to minimize the impacts of greywater on the marine environment. Also minimize discharge by doing dishes and showers on shore whenever possible.
