Yeah, good point on the septic systems.

But also highly illegal,ask the EPA or OSHA(okay don't ask OSHA unless your prepared to pay a $50,000 fine)about pouring coolant down the drain.Of course you take it somewhere if you have someplace to take it. I thought the point of this thread was the OP couldn't find anyplace to take it. When your alternatives are less good, putting it in the sewer is the best option.

Disposal of Waste Antifreeze.
Waste antifreeze is antifreeze that is contaminated or too old to be reused. Test results have shown that used antifreeze may contain lead, benzene and other contaminants at levels that make it hazardous. Waste antifreeze is considered a special waste and must be disposed of according to special waste guidelines. For specific regulations, refer to the Minnesota Pollution Control Agency (MPCA) Fact Sheet on Managing Waste Antifreeze, #4.02.
You may discharge it to a drain connected to a wastewater treatment facility only if:
You generate less than 50 gallons per month;
The wastewater treatment facility is permitted by the MPCA and has agreed to accept it.
What about the toxicity of Ethylene Glycol?
Ethylene Glycol, found in most current formulations of antifreeze, while toxic at high concentration, is highly treatable at the concentrations received by a wastewater treatment plant. It is broken down by the biological processes just like all of the other organic compounds received for treatment. Of course, the discharge of “significant quantities” (hundreds of gallons) of relatively concentrated ethylene glycol could result in a toxic condition being created at a treatment plant. However, it’s highly unlikely that the average person doing vehicle maintenance will ever release such volumes.
Managing the Waste
Do not:
• Discharge antifreeze to a storm sewer or septic system.
• Drain antifreeze onto the ground.
• Place antifreeze in solid waste.
• Mix antifreeze with used oil.
• Discharge to a sanitary sewer system if you generate 600 gallons or more per
year.
For businesses that generate 600 gallons of waste antifreeze or more per year,
management options include on- or off-site recycling or off-site disposal. On-site
recycling may be accomplished by purchasing and using your own equipment or by
using a service that will come to your site and recycle the collected antifreeze. Both
on-site methods result in a recycled product for your use.
(Services that recycle off-site do not typically return the recycled antifreeze.) If the
antifreeze is contaminated to a degree that makes it unrecyclable, you will have to
dispose of it using a reputable hauler. (Disposal is the least desirable option.) Before
recycling or disposal, store the waste in a closed and marked container.
Businesses that generate less than 600 gallons per year of waste antifreeze may
discharge it to a sanitary sewer system provided it is allowed by the local
wastewater treatment plant. (A local wastewater treatment plant may prohibit
discharge of antifreeze to its system. In the twin cities metropolitan area, Metropolitan
Council Environmental Services allows small amounts of motor vehicle antifreeze
to be discharged to the wastewater treatment plant.)
Businesses that discharge antifreeze are required to keep records showing the
amount of waste antifreeze generated. Maintain the records on site and available
for inspection for three years following generation of the waste.
I contacted the Essex County Landfill Center, who coordinates an annual Household Hazardous Waste Collection Day. They couldn't tell me where to dispose of used antifreeze either. They simply stated, "the annual Household Hazardous Waste Collection Day has already gone by."
When I asked if they knew when the next one was, they said they didn't know.
It looks like this is the best method of disposing of antifreeze safely, legally, and environmently responsible.
