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

Because of its composition, antifreeze could ordinarily qualify as a hazardous waste.  But in order to encourage recycling, the state of Ohio 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 fuel or metal particles. Used antifreeze should never be disposed of down storm drains or surface waters. It is illegal and dangerous to discharge antifreeze to septic systems or to the outdoors, and in most areas of Ohio, you also cannot dispose of antifreeze in the sanitary sewer.

Due to its composition, used antifreeze can be considered a hazardous waste. However, in the state of Ohio, used antifreeze is exempt from hazardous waste regulations if it is properly managed. The best option is to have it recycled. There are three ways you can recycle used antifreeze:

1. You can purchase a small antifreeze recycling system to use at your facility;
2. You can hire a mobile recycling company to come to your business, recycle the antifreeze and leave the recycled product for you to reuse or sell; or
3. You can hire a company to pick up your used antifreeze and recycle it at a central facility.

Note: If you recycle antifreeze on-site, you must make sure that any wastes from recycling (i.e. sludges, filters) are also evaluated to see if they are hazardous.

Used antifreeze that is not recycled and therefore, disposed of, must be handled in one of two ways:

1. 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.
2. 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 of Used Antifreeze. Whether your antifreeze is new or taken from vehicles and is reused, sold or given away for reuse, its storage may be regulated by the Ohio Environmental Protection Agency (EPA) As with the storage of used oil, secondary containment is required for the storage of antifreeze in aboveground tanks.

Labeling. Use the following labeling for antifreeze that will be recycled or reused. For hazardous wastes, see the ECAR Hazardous Waste fact sheet for labeling instructions.

• Label used antifreeze collection equipment and containers with the words "Used Antifreeze."
• Label reconditioned or recycled antifreeze containers with the words "Reconditioned or Recycled Antifreeze."
• Mark used antifreeze containers with the starting date of accumulation.

If used antifreeze at your facility is a hazardous waste, see the ECAR hazardous waste fact sheet for additional storage requirements.

Spill Control. All chemical or petroleum spills that occur within the State of Ohio must be reported to Ohio EPA.

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.

1. 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.
2. Are 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."
3. 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 Ohio EPA.
4. 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.
5. 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).
• Label used antifreeze collection equipment and containers "Used Antifreeze."
• 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.
• Consider keeping antifreeze in two separate, closed containers: one for antifreeze that cannot be reused marked "Waste Antifreeze," and one marked "Usable Antifreeze."
• Label reconditioned or recycled antifreeze containers "Reconditioned or Recycled Antifreeze."
• Label antifreeze containers with the starting date of accumulation.
• Install 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.]
• Keep any records relating to used antifreeze for at least 3 years. This includes receipts for used antifreeze shipments and any laboratory results.
• Employ the following procedure for antifreeze spills on floors:
• Mop up the antifreeze immediately using a dedicated cloth mop. Transfer collected antifreeze to the properly labeled antifreeze waste container for recycling.
• Use 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.
• Use a wet mop only if necessary for final cleaning. Use mild, non-caustic detergent.
