San Mateo County Boaters can set sail sail for cleaner waters and help make a big environmental impact. Continue reading to learn how you can make a difference. 

How Boaters in San Mateo County Can Make a Difference

Since marinas are located at the water’s edge—whether on the Pacific Ocean or San Francisco Bay—pollutants generated from boats and boat maintenance activities can pose an immediate threat to the health of aquatic systems and contribute to other environmental hazards. 

Safely recycling or disposing of used motor oil, oil filters, oil cleanup absorbents (such as bilge pads), and other hazardous waste is a simple, easy and a FREE way YOU can help make a difference in your boating community.

What is Hazardous Waste?

Hazardous waste is toxic, corrosive, flammable or reactive, based on its chemical properties. Products such as paints, batteries, antifreeze, and cleaning products are considered hazardous waste. It’s illegal and unsafe to dump this waste in the trash, ocean, or Bay. 

DID YOU KNOW that it’s illegal and unsafe to abandon or trash hazardous waste? Call the San Mateo County Household Hazardous Waste Program at (650) 363-4718 or make an appointment online. You may also see a full list of accepted items here.

Tips for A Clean & Green Boating Experience

  1. Prevent oily discharges from the bilge: Keep your engine well tuned to prevent fuel and oil leaks. Secure an oil absorbent pad or pillow in your bilge and under your engine where drips may occur.
  2. Properly dispose of used oil, filters, and absorbent materials: Do not put used oil absorbent materials in the trash. Dispose of them as hazardous waste at your marina. Have more than used oil, filters, and absorbent materials to get rid of? Make an appointment online or call (650) 363-4718 to drop-off oil and other hazardous waste for free. The facility takes a variety of products such as paints, batteries, antifreeze, and cleaning products. Click here for a full list of acceptable materials.
  3. Don’t mix your used motor oil with anything else: Used motor oil mixed with any other materials is contaminated and cannot be recycled. Contaminated motor oil can only be disposed of as hazardous waste.
  4. Spill-proof your oil changes: For oil changes, use an oil change pump to transfer oil to a spill-proof container. Use absorbent pads or rags to catch drips and spills. 
  5. Limit fuel spills: Prevent fuel spills by filling fuel tanks slowly. Don’t “top off” or overflow your fuel tank.
  6. Do not add soap: Never use soap to disperse fuel and oil spills. It increases harm to the environment and it is illegal.
  7. 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.
  8. 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 porta-potty and empty it at a harbor dump station or bathroom.
  9. Stow it, don’t 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 greywater discharges: Use a phosphate-free biodegradable soap to minimize the impacts of greywater on the marine environment.
