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
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.
Regulations
In
the state of South Dakota, 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 South Dakota 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, there must be NO free liquids
present in the accumulated rags. Any free liquids must be managed
as hazardous waste and the entire rag/solvent mixture may be considered
a hazardous waste subject to regulation.
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.
- 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.
- 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.
- 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.
