The San Francisco Bay Clean Boating Map features locations of marina-based pollution prevention services (used oil collection, sewage and bilge pump-out, oil absorbent distribution and collection, marine battery collection), mobile boat-to-boat services and helpful information about clean and safe boating practices. This map was created by the California Department of Parks and Recreation Division of Boating and Waterways. Additional information about bilge care and prevention oil spills is available CA State Parks Division of Boating and Waterways.
