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

When you absorb toxic or flammable material in a towel, you haven't made it any less toxic or flammable.  Depending on what they have been used for, shop towels may need to be managed as hazardous wastes.  But you may be able to be exempt from the full burden of hazardous waste management rules if you send your towels to a qualified commercial laundry service. If you do not send your towels out for cleaning (for example, if you use disposable towels), then the burden is on you to prove that they are not hazardous before you dispose of them.  Reusable towels and a qualified laundry service are by far the best bet.

The Nevada Small Business Development Center has prepared a guidance document to help auto recyclers manage shop towels. Much of the information is included in the fact sheet below. You can access the guidance for shop towels under “Other Relevant Resources.”


Regulations

In the state of Nevada, dirty rags/shop towels are subject to the federal RCRA hazardous waste regulations, meaning that they need to be collected in a proper container which is kept closed, labeled, dated and inspected weekly, be managed under accumulation requirements, and sent to a proper RCRA facility for disposal. However, if the contaminated rags are to be commercially laundered and reused rather than disposed of, the state of Nevada will give auto recyclers somewhat of a break by excluding them from the hazardous waste regulations. The rags/towels need to be managed as hazardous waste only until they are picked up by a commercial laundering service. However, to qualify for this exemption, you must meet the following conditions:

  • The contaminated cloth rags are free of any liquids which can be removed by the conventional practice of wringing or dripping; and
  • The contaminated cloth rags are stored in a seal-tight container at all times during on-site storage, transportation to a laundering facility, and storage prior to treatment at a laundering facility, to prevent the release of air contaminants into the surrounding environment. Evaporation is not allowed.

Failure to comply with these requirements could subject your business to enforcement actions for failure to properly contain and manage hazardous waste. It is in the best interest of any Nevada business that is generating contaminated cloth rags and paying to contract with a commercial laundering facility to ensure the facility they are contracting with is in compliance with their wastewater discharge permit issued by their local pre-treatment program. For specific information regarding contacts for the various pre-treatment coordinators located throughout the state of Nevada, contact the Business Environmental Program (BEP) at 1-800-882-3233.

You should also bear in mind that allowing solvents to evaporate from the rags in order to achieve a "no free liquids" state is not permitted. Instead, you may wish to use some sort of solvent extraction or wringing to recover excess solvent amounts if they plan to have rags laundered. Any recovered liquids should be managed in accordance with the regulations.

Finally, contaminated rags or commercial wipes regulated as hazardous waste MAY NOT be burned in a space heater, boiler, industrial furnace, incinerator, or other combustion device operated by the generator, or open burned.

If contaminated rags/used shop towels are not sent to a laundering service, then auto recyclers must determine if the dirty shop towels are hazardous or not before disposing of them. Most likely they are indeed hazardous. Therefore, they must be managed in accordance with hazardous waste regulations. See the ECAR Hazardous Waste Fact Sheet.

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 handling of used shop towels.

  1. Shop towels are exempt from regulation if they are managed correctly and picked up for laundering by a commercial laundry service. Verify that dirty shop towels are managed correctly and picked up for laundering by a commercial laundry service. You must manage your shop towels in accordance with the hazardous waste requirements until they leave your operations.
  2. Do your shop towels contain free liquids? If so, there is no hazardous waste exemption for rags or soiled clothing contaminated beyond saturation.

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 handling used shop towels.

  • If you use solvents or other materials that make your rags or wipers a hazardous waste, consider using other products which would not make you rags or wipers hazardous.
  • If you cannot replace the solvent or material you are using, consider switching from rags to paper wipes to reduce the quantity of hazardous waste which you generate.
  • Explore ways to reduce your cleaning frequency or cleanliness requirements.
  • A wire rack placed in the bottom of your container may be a good idea if liquid can flow from the rags or wipers. Use of such a rack will allow you to collect the liquid solvent in the bottom of the container and separate it from the rags. This recovered solvent may be suitable for reuse or recycling.
  • Avoid using disposable towels. Use cloth towels from an industrial laundry service that is discharging its wastewater into a public sewer system.
  • Do not dispose of solvents by pouring them onto rags or into containers of used shop towels.
  • Do not saturate your towels. If you do, wring them out and reuse the liquid.
  • Spray minimum amount of solvent onto rags instead of soaking rags.
  • Use non-hazardous solvents whenever possible.
  • Do not throw dirty wipes, paper towels or rags into the dumpster if they have come into contact with hazardous solvents or waste.
  • Do not dispose of dirty shop towels in vehicles to be crushed or shredded.
  • Keep waste shop towels in a closed, fireproof metal container labeled "Used Shop Towels."
  • To reduce the risk of spontaneous combustion when storing shop towels in metal cans, keep the towels moist with water.
  • Examine your equipment cleaning practices to identify opportunities to reduce their frequency, thereby reducing the number of towels, wipes, or rags that are used for this purpose.
  • Maintain records of analytical waste determinations and disposal receipts for at least 3 years.
