How do I responsibly get rid of 10 gallons of contaminated gasoline?

Actually, I was hoping to see an answer.
I had a boat with 12 year old fuel and called all the marine service folks in town.
No one would empty the tank and dispose of the fuel.
I ended up pouring a lot of STA-BIL into the tank and running around the lake until it was down to about 10% of the tank.
Smoke, uh-huh! Probably not too good for the 2-stroke engine.

holy feck. I'm surprised anything ran on 12yo unleaded. Maybe it was just 90% stabil by that point?

Was down to about 60 gals in a 120 gal tank, so I put in another 40 gals, lots of STA-BIL, and ran it out.
Fresh gas after leaving about 12-15 gals in the tank, up to about 100 gals, and the engine ran fine.
Lucked out there, but would have preferred draining the old gas and starting over.
