Antifreeze should not be emptied down a municipal sewer or a storm drain. It is very toxic and will kill a dog, cat or even a small child if they happen to lick it off the driveway. You might try finding a local service center that might take it from you but usually at a price. I always have a service center do my antifreeze change, then it is their problem for disposal. With waste oil some service centers have waste oil furnaces for heat and are more than happy to take your waste oil. Good Luck.
