Our local dump/transfer station/recycling cccenter has a free "hazardous" waste day, first Saturday, every month. Your local "hazardous" waste handling procedure most likely will differ, give them a call.
They may also have a limit on the number of gallons, packaging, or marking. A little checking on requirements will ease the disposal.

Some times, they will return your gas can/container, again checking will avoid some un happiness/grief at the possible loss of your favorite Jeep gas can.
