Totally depends on where you live.
Sadly, some places don't have hazardous waste collection programs. Here, we just take it to the city facility that collects it, along with all of our other automotive fluids, paints, batteries, etc.
If you don't have that option, you should just call your local municipality and ask them. In some states they will say it's OK to put it in the sewer. When you call you could mention how much you'd like to have a better way to dispose of it...
