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
Indiana's hazardous waste rules, ethylene glycol and propylene glycol,
the chemicals that make up antifreeze, are not listed hazardous
wastes. However, contact with cooling system parts may cause used
antifreeze to become contaminated with heavy metals, such as lead,
chromium and cadmium. This contamination may make the antifreeze
a hazardous waste. Or used antifreeze that is mixed with other wastes
during storage may result in a mixture that is a hazardous waste.
Indiana Department of Environmental Management (IDEM) has prepared
a guidance document to help auto recyclers manage used antifreeze.
Much of that information is included in the fact sheet below. You
can access the link to IDEM's Compliance Manual for Auto Salvage
Facilities under Other Relevant Resources.
Classification. Because antifreeze
can become contaminated either through use or during storage, it
may be considered a hazardous waste. Each facility is responsible
for making a hazardous waste determination on its used antifreeze.
This determination can be based on analytical test results of the
used antifreeze, or it may be based on the knowledge of the waste
and how it was generated and managed.
If your used antifreeze is considered
to be a hazardous waste, you must manage it according to the hazardous
waste rules. Listed below are the proper management requirements
or see the ECAR Hazardous Waste Fact Sheet for more detailed information.
- Label all containers in accordance with the hazardous
waste rules. Remember to clearly mark the words “HAZARDOUS WASTE”
as well as the date the waste began to accumulate (or the date
the container was completely filled if there is a satellite accumulation
area onsite) on the used antifreeze container.
- Keep storage containers closed to prevent evaporation
- Conduct weekly inspections to ensure that the
containers are in good condition. Look for leaks and for deterioration
caused by corrosion or other factors. If a container leaks, put
the hazardous waste or the leaking drum in another container.
- Keep monthly records of the amount of used antifreeze
that is accumulated.
- Manifest drums of used antifreeze to a TSD facility
- Use only permitted waste transporters that have
obtained an EPA identification number to transport drums of antifreeze
If your determine your used antifreeze
is not a hazardous waste, you must:
- Never put antifreeze into the environment (i.e.
onto the ground or into streams).
- Never pour antifreeze into any drains if a facility
is on city water, unless the local wastewater treatment plant
has been contacted in order to make sure it can handle such a
- Not discharge antifreeze to a septic system if
doing so will result in the antifreeze entering and causing harm
to the waters of the state of Indiana. Note that, if a facility's
used antifreeze is determined to be a hazardous waste, it must
not discharge it to a septic system or to the environment.
- If a facility recycles antifreeze on-site, a
hazardous waste determination must be made on the filters and
sludge, or they can be treated as hazardous wastes. Because the
contaminants are concentrated in the filter and/or sludge, it
is likely that these may be hazardous wastes.
Used antifreeze can be recycled, but there are things to
keep in mind. You may recycle your antifreeze on-site or off-site.
Remember that if you recycle your antifreeze on-site, the fi lters
and sludge that are generated during the recycling process may be
hazardous wastes. If recycling on-site, a hazardous
waste determination must be made and the waste must be managed accordingly.
If this service is contracted to an outside company that recycles
used antifreeze off-site, that company will be responsible for the
hazardous waste generated during the recycling process.
A list of antifreeze recycling companies
is included in IDEM's manual for auto salvage yards. See the link
under Other Relevant Resources.
Spills. Under IDEM's Spill Rule, a spill
is defined as a release of more than one pint or one pound of an
objectionable substance (such as antifreeze) that could threaten
to enter the ground water or surface water of the State of Indiana.
Spills that occur on your property must be immediately cleaned up
and properly disposed.
Not all spills are reportable. As
a general rule, all spills should be reported if they:
- Create a risk to public health from fire or explosion;
- Are not contained within a building;
- Come in contact with soil or water; or
- Leave the property, or threaten to enter the
waters of Indiana (including ground water).
you determine that the spill must be reported, do so by calling
IDEM's Environmental Emergency Hotline as soon as possible, but
no later than two hours after the incident, by calling 317/233-7745
or toll free at 888/233-7745.
to the Regulations. Use
the following links to view the regulations pertaining to used antifreeze
Indiana Hazardous Waste Resources
EPA Standards Applicable to Generators of Hazardous Waste
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
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 IDEM within 2 hours.
- 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
- 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.
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
- 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."
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.
- For more information, contact the Indiana Department of Environmental
Management (IDEM) at 800-451-6027 or 317-232-8603.
- Report spills and environmental
emergencies immediately to IDEM by telephone at 1-888-233-7745.
- Submit a pollution complaint online
through the IDEM Pollution
