The
following fact sheet was prepared by the ECAR Center staff. Once
prepared, each ECAR Center fact sheet undergoes a review process
with the applicable state environmental agency(ies). You can check
on the status of the review process here.
Please read the disclaimer on the status page. While we have tried
to present a summary of the essential information on this topic,
you should be aware that other items, such as local regulations,
may apply to you.
What You Need to Know
Used
antifreeze, through contact with a car's cooling system, may contain
traces of lead and benzene, making it a possible hazardous waste. If not properly managed and stored,
these pollutants can seep into soil and groundwater harming people
and the environment.
But
in order to encourage recycling, the State of Georgia will give
you a break and exempt you from the burden of handling it according
to the usual hazardous waste rules if you manage it properly.
This fact sheet will tell you:
- How to handle antifreeze to qualify for the exemption.
- What you need to do if you do not qualify in order to
manage antifreeze in compliance with hazardous waste rules.
Regulations
Waste
Classification.
Antifreeze is made up using some regulated chemicals including ethylene
glycol and propylene glycol. During use, antifreeze can become contaminated
with traces of benzene and lead. Used antifreeze should never be
disposed of down storm drains or surface waters. It is illegal and
dangerous to discharge antifreeze to septic tanks, dry wells or
to the outdoors.
Due
to its composition, used antifreeze can be considered a hazardous
waste. However, if used antifreeze is recycled, it doesn't need
to be treated as hazardous waste. The Oregon Department of Environmental
Quality (DEQ) has determined that antifreeze that is recycled and
managed in accordance to Best Management Practices (BMPs) generally
will not exhibit hazardous waste characteristics and will not need
to be handled as hazardous waste.
You
may be able to discharge your used antifreeze to a water treatment
facility (with prior approval from the facility). However, many
water treatment plants prohibit the disposal of antifreeze because
of the potential of damaging the system.
Used
antifreeze that is not recycled and therefore, disposed of, must
be handled in one of two ways:
- Have a sample of the used antifreeze analyzed by a laboratory
to find out if it is hazardous. If it is non-hazardous, it can
be shipped off-site for disposal by a licensed hauler or discharged
to a municipal wastewater treatment system. You must check with
your local water treatment authorities and a permit may be required).
If it is hazardous, then special hazardous waste rules apply.
- Assume that the antifreeze is hazardous and manage it
as such. This approach avoids laboratory testing costs.
See
the ECAR Hazardous Waste fact sheet for details about storing,
handling, and shipping of hazardous wastes.
Storage
and Labeling. Store antifreeze in closed containers
on an impermeable concrete surface with spill controls. Consider
keeping antifreeze in two separate, closed containers: one for antifreeze
that cannot be reused marked “Waste Antifreeze Only,” and one marked
“Usable Antifreeze Only.”
Spills. Clean up all spills
right away. Keep spill control equipment in a central location,
accessible to all employees. Non-recyclable spill cleanup wastes
must undergo a hazardous waste determination.
Filter
Management. Waste antifreeze filters and particulate
generated from recycling antifreeze also must be managed as hazardous
waste or proven that they are non-hazardous through laboratory analysis.
See the ECAR Hazardous Waste fact
sheet for additional information.
Record
Keeping. Keep all receipts of used antifreeze
shipments and filter management. The written receipts or records
must include:
- Name and address of the generator and the recycling
facility for off-site shipments.
- The amount of used antifreeze shipped or recycled on-site.
- The amount of waste antifreeze filters shipped off-site.
- Date of shipment or recycling.

Self-Audit
Checklist
When
an inspector comes to your facility, there are certain things he
or she checks to see if you are in compliance with environmental
regulations. It makes good sense for you to perform a "self-audit"
and catch and correct problems before they result in penalties.
Also, there are some compliance incentives associated with self-audits
(see Audit
Policy Page).
Use
the following list to audit your antifreeze storage areas and management
procedures.
- Is used
antifreeze stored in drums, tanks or other containers that are
in good condition? Open
containers, and rusting or leaking containers cannot be used
for antifreeze storage.
- Are
antifreeze storage containers and tanks properly labeled? All waste antifreeze should be labeled
“Waste Antifreeze Only,” and antifreeze that can be recycled
or reused, should be marked “Usable Antifreeze Only.”
- Is
the area around the used antifreeze storage containers free
of releases? Releases must be stopped; the released
material cleaned up and managed properly and reported to DEQ.
- Is
used antifreeze transported to a recovery facility by a certified
transporter? Check your records and verify that
all shipments of used antifreeze were removed from your property
by a state certified transporter.
- Is
oil, solvent or other materials mixed with used antifreeze? Verify that there are separate,
clearly labeled containers for each type of material, and that
used antifreeze is not mixed with used oil, solvents and other
materials.
Best
Management Practices (BMPs)
Most
regulations tell you what you have to do to be in compliance, but
they don’t explain how to do it. That’s where "best management
practices" come into play. BMPs are proven methods that
help you to get into compliance and stay there. The following BMPs
are recommended for used antifreeze storage areas and management
procedures.
- Use separate
equipment for the collection of used antifreeze (funnels, pads,
storage containers).
- Drain
antifreeze from radiators and heater cores as soon as possible.
- Keep
waste antifreeze free from cross-contamination with other wastes,
including used oil, fuels, degreasers or radiator flush chemicals.
Once contaminated with other wastes, antifreeze will need to
be handled as hazardous waste.
- Determine
if the antifreeze is waste fluid or reusable and can be recycled.
- Recycle
by reuse, distillation, filtration or ion exchange. Recycling
can be done on-site or off-site by an antifreeze recycling service.
- Consider
keeping antifreeze in two separate, closed containers: one for
antifreeze that cannot be reused marked "Waste Antifreeze,"
and one marked "Usable Antifreeze."
- Do
not dispose of antifreeze down storm drains, in septic tanks,
dry wells or on bare ground.
- Volumes
of accumulated antifreeze are minimized by routinely recycling
to reduce the potential for environmental harm.
- Keep
any records relating to used antifreeze for at least 3 years.
This includes receipts for used antifreeze recycling shipments
and any laboratory results.
