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
Wipe/Towel Laundering.
Dirty shop towels are exempt from the RCRA 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). An industrial wastewater point
source discharge that is subject to Section 402 of the Clean Water
Act (NPDES permit) also qualifies for this exemption.
The exemption from RCRA regulation
does not apply where laundering waste discharge is not regulated
under the Clean Water Act. Some examples include discharge into
a septic system/leach field or an unpermitted direct discharge.
The operator must accumulate wipes
appropriately and safely (e.g., in a closed container as opposed
to placement in a waste pile or other land disposal unit) to prevent
the release of contaminants to the environment. Even though wipes
that are to be laundered are not regulated as a hazardous waste,
any release or contamination due to the mismanagement of contaminated
wipes is a violation of North Carolina law.
You may not mix hazardous waste with wipes to be sent to laundering
facilities.
You cannot dispose of hazardous waste at a commercial laundry simply
because it is contained in an absorbent that is to be laundered.
Absorbents specifically designed to contain releases and absorb
significant amounts of contaminants (e.g., pig or booms), and wipes
used to contain spills or releases, do not qualify for the laundering
exemption. They are considered "solid wastes" and must
be managed subject to RCRA regulation.
Disposal. If a shop towel service
is not used, then you must determine if your dirty shop towels are
hazardous or not before disposing of them. The North Carolina Department
of the Environment and Natural Resources (NCDENR) provides guidance
to businesses to help them determine if the wipes are hazardous,
and if so, what type of hazardous waste. If the towels are hazardous,
then you must manage them in accordance with hazardous waste regulations. Click

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.
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.
- 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.
