Avoid USCG $10,000 fine
David W. is in British Columbia and would have to worry about Canada's regulations, but the rest of you guys need to be aware that there's a $10,000 or more fine for dumping fuel and related fluids if you are deemed to be careless or if the quantity requires a cleanup. I had to have the local fire department come and had to file a report with them when I spilled a half-pint into the water while refueling at a Long Island Sound marina; didn't get fined, but I wouldn't think of trying the engine degreasing routine on the water after that...
