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, often contains
heavy
metals such as lead, cadmium, and chromium in high enough levels
to make it a regulated hazardous waste.
If not properly managed and stored,
these pollutants can seep into soil and ground water harming people
and the environment.
But
in order to encourage recycling, the State of Wisconsin 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.
The
Wisconsin Department of Natural Resources (DNR) has prepared a comprehensive
guidance document on handling used antifreeze. Much of the information
contained in the document is included in the fact sheet below.

Relevant Resources.”
Regulations
Antifreeze Recycling. Used antifreeze recycling methods involve two steps:
- Removing contaminants either by filtration,
distillation, reverse osmosis, or ion exchange, and
- Restoring critical antifreeze properties with
additives. Additives typically contain chemicals that raise and
stabilize pH, inhibit rust and corrosion, reduce water scaling,
and slow the breakdown of ethylene or propylene glycol.
DNR strongly encourages the recycling of used antifreeze (which is sometimes
called "used engine coolant" or "used ethylene or propylene
glycol"). Antifreeze becomes a waste if the original user or
generator can no longer use it as antifreeze or coolant.
If it is recycled, it is considered "Wisconsin specific universal
waste," which is easier and less expensive to manage.
Under the universal waste rules,
you are considered a handler if you:
- Generate used antifreeze or:
- An owner or operator of a facility that receives
used antifreeze from other handlers, accumulates the antifreeze,
and sends the antifreeze to
another
handler or to a destination facility.
There
are two types of universal waste handlers:
- A "Small Quantity Handler" accumulates
less than a combined total of 5,000 kilograms (approximately 1,250
gallons) of universal wastes on-site at any one time.
- A "Large Quantity Handler" accumulates
5,000 kilograms (combined total) or more universal wastes on-site
at any time.
The
following are the requirements that apply to both types of handlers.
Storage. Containers and tanks used by handlers to accumulate used
antifreeze on-site should meet all of the following requirements:
- Be structurally sound and chemically compatible
with the antifreeze;
- Remain closed and sealed at all times except
when antifreeze is being added or removed;
- Show no evidence of leakage, spillage, or damage;
- Be clearly labeled or marked: "Used Antifreeze."
You
SHOULD NOT MIX used antifreeze with solid or hazardous waste or
other materials such as solvents or oil. Mixing the used antifreeze
with other
substances may inhibit its ability to be recycled and may cause it to become
hazardous waste.
Monitoring
Used Antifreeze Quantities. Handlers may accumulate used antifreeze for one year from
the date the used antifreeze is generated or received from another
handler. Handlers may only accumulate used antifreeze for longer
than one year from the date the waste is generated or received from
another handler if such activity is solely for the purpose of accumulating
such quantities as is necessary to facilitate proper recovery.
Handlers should demonstrate the length of time the used antifreeze has accumulated,
starting from the date the antifreeze became waste or was received.
The handler may demonstrate length of time by:
- Marking or labeling containers with the accumulation
start date, or
- Maintaining an inventory system on-site that
identifies the earliest date antifreeze was added to a container
or was received from off-site.
Employee Training. The handler should ensure that all employees are thoroughly familiar with proper
waste handling and emergency procedures.
Respond to Releases. Handlers should immediately contain
and clean up all releases of antifreeze. Any residues resulting
from the cleanup of antifreeze spills or leaks that exhibit a characteristic
of hazardous waste should be managed according to the applicable
requirements of chapters. NR 600 to 685, Wis. Adm. Code. Handlers
are required to report spills of hazardous substances to the Wisconsin
Division of Emergency Management at 1-800-943-0003.
Large
Quantity Handlers should also meet all of the following additional
requirements:
Notification.Large quantity handlers should
notify DNR prior to accumulating used antifreeze, unless they have
previously notified the DNR and EPA of their hazardous waste activity
and received an EPA identification number. The notification form
can be found under “Links to the Regulations and Forms.”
Record Keeping.Large quantity handlers
should keep records for three (3) years on each shipment of universal
waste received or sent. These records should include the date of
each shipment, the quantities of each shipment, and the name and
address of the handler or facility from which used antifreeze was
received or shipped to.
Antifreeze
Disposal
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. 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.
Auto
Recyclers in Wisconsin should be aware of the following regulations:
- It is illegal to discharge any hazardous waste
including used antifreeze into a sanitary sewer. If you want to
discharge used antifreeze, you must have data showing it's not
hazardous and you must have permission from the treatment plant.
- It is always illegal to dump used antifreeze
into a storm sewer or on the ground. Illegal dumping is harmful
to lakes and streams, and may harm people, pets or wildlife.
- Discharging it into a septic tank and soil absorption
field is illegal and will cause
groundwater
pollution. It could also cause the septic system to fail.

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 the Department of Ecology.
- 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.
- 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.
- Keep any records relating to used
antifreeze for at least 3 years. This includes receipts for used
antifreeze shipments and any laboratory results.
