But, seriously, local waste collection agencies (whoever picks up your trash) take chemical waste. I know ours pick up used motor oil. I'd give them a call and see if they'll take it, or you can go to Autozone or Kragen. They might take it too.
I dumped about a gallon of 10-year old gas from my dad's motorcycle into his Civic... the Civic didn't like the gas too much, but it ran on it. That was about 2 years ago and my dad's civic is still OK now...
