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 industrial laundry service. (The
service has to discharge its wastewater into an approved wastewater
treatment facility -- it can't discharge directly to a river or
stream, for example.) 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.
This
fact sheet will help you recognize some of the most common materials
that can turn shop towels into hazardous wastes.
Regulations
Dirty
shop towels are exempt from hazardous waste regulation if they are
managed correctly and picked up for laundering by an industrial
laundry service that is connected to a publicly owned treatment
works facility (POTW). All shop towels/solvent wipers are eligible
for this exclusion if the wipers contain no free liquids and are
sent to a commercial laundry that is subject to regulation under
the Clean Water Act or a dry cleaner. Let the cleaning company know
what type of chemicals you are using with the towels so they can
determine the best way to clean them and the affect on their own
waste stream.
All
rags and soiled clothing that contain flammable materials must be
stored and transported in fireproof containers.
If
shop towels are not reused, then you must determine if your dirty
shop towels are hazardous or not before disposing of them. Towels
that are spontaneously combustible are a D001 hazardous waste. Towels
may be a listed waste depending on what and how solvents are used.
If the towels are hazardous, which they most likely are, then you
must manage them in accordance with hazardous waste regulations.

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 an industrial laundry service
that is connected to a publicly owned treatment works facility
(POTW). Verify that dirty shop towels are managed correctly
and picked up for laundering by an industrial laundry service
that is connected to a publicly owned treatment works facility
(POTW). 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.
- Keep
waste shop towels in a closed, fireproof metal container labeled
"Used Shop Towels." If being handled as hazardous
waste, then label the containers with the date waste first put
in container, the waste code, and the words “Hazardous Waste.”
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 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.
