ECAR
Fact Sheet for Missouri
Regulations BACK to VIRTUAL TOUR 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 Antifreeze is usually made of ethylene glycol, corrosion inhibitors and foam controllers. Ethylene glycol is toxic if ingested. It is particularly dangerous because animals and children are attracted to its sweet flavor. If they drink the ethylene glycol it may cause coma or death. Some antifreeze is made of propylene glycol. This material is less hazardous to humans and animals than ethylene glycol. The used antifreeze from a vehicle can hold contaminants that it has picked up from the vehicle engine. For example, used antifreeze may contain lead because the antifreeze has dissolved some of the lead solder in the radiator. The Missouri Department of Natural Resources 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 the Department's Vehicle Salvage Compliance Guide under Other Relevant Resources. Waste Classification. Waste antifreeze is not a listed hazardous waste under the federal hazardous waste regulations. However, it may be a hazardous waste depending on the contaminants it has picked up. The test used to find out if used antifreeze is a hazardous waste is called the Toxicity Characteristic Leaching Procedure (TCLP).Recent studies have shown that antifreeze from cars and trucks manufactured after 1995 is not hazardous waste. This is primarily because less lead is used in radiator construction. Used antifreeze is more likely to be hazardous if it was used in heavy equipment such as bulldozers and buses. This means that antifreeze from late-model cars and trucks that has not been mixed with other antifreeze or with other hazardous wastes does not need to be tested. In this case, you may assume that it is not hazardous and need not test it. However, used antifreeze from heavy equipment or industrial sources will need to be tested to see if it is hazardous waste unless you have some other way of knowing that it is or is not hazardous. If you wish, you can assume the antifreeze from your heavy equipment is hazardous without testing it. You would then need to dispose of it as hazardous waste. If your used antifreeze is determined 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.
Recycling. The Department strongly encourages antifreeze recycling. If you want to recycle your hazardous waste antifreeze on-site you must notify Department. If you recycle 2,200 lbs. or more in a month, you need a resource recovery certification. If you recycle antifreeze only from late-model cars and trucks, you do not need a resource recovery certification. Your recycling unit will create waste such as distillation residues or used filters. You must determine if these wastes are hazardous before disposal. If the residue is nonhazardous, it can be sent to the landfill with your regular trash. However, liquids cannot go to the landfill. There may be businesses that will bring equipment to your facility and recycle your antifreeze on-site. Again, if the antifreeze is from late model cars and trucks, these companies do not need resource recovery certification. If it is from heavy equipment or older cars, these companies will need resource recovery certification to recycle your antifreeze. Off-site Recycling or Disposal. There are companies that pick up used antifreeze for off-site recycling or disposal. If your used antifreeze is a hazardous waste, the transporter must have a Missouri license to transport hazardous waste and the waste must have a hazardous waste manifest with it. Make sure the facility you send it to has a resource recovery certification or a hazardous waste treatment, storage and disposal permit. Discharge to wastewater treatment plant pouring it down the drain). If the drains at your facility go to a wastewater treatment plant (not a septic system), you may be able to pour antifreeze down the drain IF you have permission from the plant. Pouring wastes down the drain is called a discharge. Some plants will not allow discharges of used antifreeze. Large quantities can harm the treatment plant. The wastewater treatment plant may not be able to remove all the contaminants from the used antifreeze. The contaminants then enter lakes, streams and rivers. A list of permitted recyclers and transporters in Missouri are listed under “Other Relevant Resources.” Spills. Notification of hazardous substance releases must be made to the Department hot line at (573) 634-2436, or the National Response Center at (800) 424-8802, at the earliest practical moment upon discovery. The following information must be provided:
Upon request, written follow-up notifications are required for releases of hazardous and extremely hazardous substances. Links to the Regulations. Use the following links to view the regulations pertaining to used antifreeze management. Missouri Hazardous Waste Regulations (Division 25) Federal EPA Standards Applicable to Generators of Hazardous WasteWhen 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.
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.
