Classification. Antifreeze is made up using some regulated chemicals
including ethylene glycol and propylene glycol. During use antifreeze
can become contaminated with traces of fuel or metal particles. Due
to its composition, used antifreeze can be considered a hazardous
waste. However, in the state of Florida, used antifreeze is exempt
from hazardous waste regulations if it is properly managed and:
chose not to recycle used antifreeze, you have two choices:
is used in your facility vehicles;
away for reuse; or
for recycling either on-site or by an off-site recycler. If you
use an off-site recycler, you must ensure that the
antifreeze is being recycled.
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.
that the antifreeze is hazardous and manage it as such. This approach
avoids laboratory testing costs.
the ENVCAR Hazardous Waste fact sheet for details about storing,
handling, and shipping of hazardous wastes.
of Used Antifreeze. Used antifreeze must be stored in containers
meeting DOT specifications/UN performance criteria and must be in
good condition. This means:
bulging or major dents; and
not accumulate used antifreeze for longer than 180 days.
Use the following labeling for antifreeze that will be recycled
or reused. For hazardous wastes, see the ENVCAR Hazardous Waste
fact sheet for labeling instructions.
used antifreeze collection equipment and containers with the words
reconditioned or recycled antifreeze containers with the words
"Reconditioned or Recycled Antifreeze."
used antifreeze containers with the starting date of accumulation.
used antifreeze storage tanks larger than 550 gallons must be registered
with DEP. To find out how to register a tank, call the DEP Storage
Tank Regulation Section at 850-488-3935. If you plan to replace
a storage tank or remove a tank from service, notify DEP before
you begin the work.
used antifreeze at your facility is a hazardous waste, see the ENVCAR
Hazardous Waste fact sheet for additional storage requirements.
Control. If a spill occurs, you must perform the following cleanup
the released antifreeze;
up and properly manage the released antifreeze and other materials;
necessary, repair or replace any leaking antifreeze storage containers
or tanks prior to returning them to service.
Best Management Practices for additional instruction on antifreeze
you store used antifreeze outdoors, the storage area must be addressed
in your Spill Prevention and Countermeasures (SPCC) Plan (see ENVCAR
Fact Sheet Spill Prevention and Countermeasures (SPCC) Plan).
used antifreeze at your facility is a hazardous waste, see the ENVCAR
Hazardous Waste fact sheet for additional requirements.
Management. You must either manage waste antifreeze filters
as hazardous waste or prove that they are non-hazardous through
laboratory analysis. See the ENVCAR Hazardous Waste fact sheet for
Keeping. Keep all receipts of used antifreeze shipments and
filter management. The written receipts or records must include:
and address of the generator and the recycling facility for off-site
amount of used antifreeze shipped or recycled on-site.
amount of waste antifreeze filters shipped off-site.
of shipment or recycling.

pertaining to used antifreeze storage and management.

Guidance on the Management of Antifreeze Destined for Recycling
an inspector comes to your facility, there are certain things they
check 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
the following list to audit your antifreeze storage areas and management
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.
antifreeze storage containers and tanks properly labeled? All
used antifreeze storage containers must be labeled "Used
Antifreeze"." All recycled or reconditioned antifreeze storage
containers must be labeled "Recycled or Reconditioned Antifreeze."
the area around the used antifreeze storage containers free
of releases? Releases must be stopped and the released material
cleaned up and managed properly.
outdoor used antifreeze storage areas addressed in your Spill
Prevention and Countermeasures (SPCC) Plan? Your SPCC must
identify potential sources of stormwater pollution and specify
appropriate measures to reduce the discharge of pollutants.
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. You can check on your transporters
certification by contacting DEP.
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)
regulations tell you what you have to do to be in compliance, but
they dont explain how to do it. Thats 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.
separate equipment for the collection of used antifreeze (funnels,
pads, storage containers).
used antifreeze collection equipment and containers "Used
antifreeze from radiators and heater cores as soon as possible.
waste antifreeze free from cross-contamination with other wastes,
including used oil, fuels, degreasers or radiator flush chemicals.
if the antifreeze is waste fluid or reusable and can be recycled.
keeping antifreeze in two separate, closed containers: one for
antifreeze that cannot be reused marked "Waste Antifreeze,"
and one marked "Usable Antifreeze."
reconditioned or recycled antifreeze containers "Reconditioned
or Recycled Antifreeze."
antifreeze containers with the starting date of accumulation.
an antifreeze recycling system. [Waste antifreeze recycling
methods involve two steps: (1) removing contaminants either
by filtration, distillation, reverse osmosis, or ion exchange
and (2) 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 glycol.]
any records relating to used antifreeze for at least three years.
This includes receipts for used antifreeze shipments and any
the following procedure for antifreeze spills on floors:
up the antifreeze immediately using a dedicated cloth mop. Transfer
collected antifreeze to the properly labeled antifreeze waste
container for recycling.
rags to dry the floor. Place used rags in properly labeled waste
containers and send rags to an industrial laundry. Do not saturate
the rags; otherwise you will have drips on the floor as you
transfer them to the waste containers.
a wet mop only if necessary for final cleaning. Use mild, non-caustic

the State Warning Point by phone at (850) 413-9911.
