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 Rhode Island, 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 Rhode Island 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.
Shop towels that are contaminated
with a hazardous waste are classified as a characteristic waste,
unless absorbents soaked with materials that
are considered
hazardous waste also are considered
hazardous waste. But, in the case of rags/towels, if they are not
soaked (dripping) and they meet the following conditions, they are
not considered hazardous waste:
- They must
be laundered at an appropriate facility
- They
must be stored in containers away from a source of ignition
- No other
waste can be mixed with rags.
You should reduce the amount of material
on your shop towels as much as possible.
Shop towels saturated (dripping)
with liquids that are considered hazardous wastes (such as solvents),
must be handled as hazardous wastes. Towels with only minor contamination
must also be handled as hazardous waste unless they are sent off-site for laundering
at a properly licensed commercial laundry.
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 only if they are managed correctly
and picked up for laundering by a commercial laundering service. Verify that dirty shop towels are
managed correctly and picked up for laundering by an 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 commercial laundry
service.
- 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.
