ECAR
Fact Sheet for North Dakota
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 Used antifreeze, through contact with a car’s cooling system, may contain traces of lead and benzene, making it a possible hazardous waste. If not properly managed and stored, these pollutants can seep into soil and groundwater harming people and the environment. But in order to encourage recycling, the State of North Dakota 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:
The North Dakota Department of Health, Division of Waste Management (the Department) has prepared a guidance document to help auto recyclers manage antifreeze. Much of that information is included in the fact sheet below. You can access the antifreeze guidance link under Other Relevant Resources. 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 benzene and lead. Used antifreeze should never be disposed of down storm drains or surface waters. It is illegal and dangerous to discharge antifreeze to septic tanks, dry wells or to the outdoors. How to Manage Used Antifreeze. To manage used antifreeze, you can reuse it, recycle it, or dispose of it. The North Dakota Department of Health, Environmental Health Section, Division of Waste Management (the Department), encourages the reuse and recycling of used antifreeze whenever possible. Recycling used antifreeze. Used antifreeze may be reused (recycled) by removing the suspended solids through filtration, and then replacing that used antifreeze back into the vehicle’s cooling system. This may require adding fresh antifreeze and water to the cooling system in order to meet manufacturer specifications. Methods of recycling of used antifreeze include simple filtration to distillation and reverse osmosis with the addition of rust inhibitors and other additives. Once recycled, the used antifreeze can then be mixed with new antifreeze to the manufacturer’s recommended antifreeze/water ratio or to the temperature protection standard. If you recycle on-site, filters and sludges produced from recycling may be hazardous. Therefore, you will need to determine if these wastes are hazardous. Disposing of used antifreeze. Discharging used antifreeze to your local, publicly owned treatment works (POTW) may be allowed. Check with your local POTW to determine if they allow this practice, and if so, what requirements are to be met. See the ECAR Hazardous Waste fact sheet for details about storing, handling, and shipping of hazardous wastes. Storage and Labeling. Store used antifreeze in containers that are clearly marked or labeled with the words “used antifreeze.” Store antifreeze in closed containers on an impermeable concrete surface with spill controls. Spills. Clean up all spills right away. Keep spill control equipment in a central location, accessible to all employees. All incidents which may potentially impact human health or safety, waters of the state, either surface water or ground water, or other impacts to the environment, must be reported. 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:
Links to the Regulations. Use the following links to view the regulations pertaining to used antifreeze management. North Dakota’s Hazardous Waste Management Requirements Federal 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 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.
