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
If your wastewater is currently just
going down an unregulated drain, you've got a problem. Even
if your activities have gone unnoticed for years, there is an increasing
chance that you will be inspected. The federal EPA and the
states are starting to look much more carefully at sources of water
pollution that have so far remained unidentified, and they have
(rightly or wrongly) decided that auto recyclers are a significant
problem area.
There are a few basic rules to keep
in mind. The first is that wastewater from industrial discharges
is usually handled by wastewater treatment plants, but you are usually
required to conduct "pretreatment" of the discharge. The
second is that the storm drains that carry rain and snow runoff
from dismantling yards, roof downspouts, parking lots, and other
surfaces typically go directly to open waterways, and must never be used for disposal. It is important that all the employees
at your yard are aware of these rules, and that they respect them.
You will almost certainly need separate
permits both for stormwater runoff (see the ECAR
Stormwater fact sheet) and
for any industrial wastewater that you generate. This page
will give you an overview of how to handle your industrial wastewater.
Regulations
An auto salvage business may generate
process wastewater from equipment cleaning, car washing, paint spray
bottles or other sources. Under Ohio EPA’s regulations, options
for handling wastewater include direct and indirect discharges.
Industrial Wastewater: Direct
Discharges. Any discharge of industrial wastewater to "waters
of the state" will require a discharge permit (NPDES) from
Ohio EPA’s Division of Surface Water. Examples of waters of the
state include: streams, rivers, lakes, ponds, marshes, watercourses,
waterways, wells and springs. Wastewater discharges entering a conveyance
system (like a ditch or storm sewer) that leads to a waterway may
also require an NPDES permit.
You may also be required to treat wastewater
to remove harmful contaminants (e.g. metals, chemicals, oils or
grease) before it is discharged. If treatment is required, a separate
permit is needed to construct wastewater treatment units, called
a permit-to-install (or PTI). The PTI application is reviewed by
Ohio EPA’s Division of Surface Water. More information is available
under the ECAR Stormwater
fact sheet.
Industrial Wastewater: Indirect
Discharges. Often, the local wastewater treatment plants (POTWs)
are responsible for regulation the companies that discharge wastewater
to them. A large POTW may be able to handle the wastewater from
your business. However, even large wastewater treatment plants are
not generally designed to handle sewage related wastes and wastewater.
Because of this, the treatment plant may require you to conduct
"pretreatment" (oil/water separation, removing solids,
chemicals, etc.) before discharging your wastewater to them.
If you want to discharge industrial
wastewater to a local POTW, you need to discuss these activities
with the plant directly. Permission to discharge to the POTW and/or
obtaining a permit may be necessary. If you are required to construct
wastewater treatment or storage units, this activity requires a
permit to install (PTI) from Ohio EPA.
Note: Ohio EPA’s regulations
prohibit the discharge of process wastewater into injection wells
without a permit. Examples of injection wells include dry wells,
drain fields, and cesspools. In addition, a septic tank, mound system
or leaching line is defined as an injection well system. For more
information, see the Septic
Tanks and Disposal Wells 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
wastewater management activities.
- Does your facility discharge
industrial wastewater? Are the discharges authorized by a permit?
Check all uses of water and steam within the industrial areas
of your facility. Determine where wastewater is generated and
discharged. You must have a permit or written authorization for
all industrial water discharges.
- Is oil or solvent discharged
to the sewer? Federal and state laws prohibit the discharge
of oil or flammable solvents to the sewer system. These are regulated
wastes that must be properly disposed of.
- Does your facility discharge
industrial wastewater to a septic tank? If yes, you must have
permit. For more information see the Septic
Tanks and Disposal Wells Fact Sheet.
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 wastewater management.
- Limit water use and the volume
of water discharged through conservation methods and by reusing
water whenever possible.
- Train employees to use water efficiently.
- Don’t use water for cleaning floors
and equipment unless absolutely necessary. Use dry cleanup methods
for spills.
- Post signs at all floor drains
and sinks in industrial areas of your facility to discourage employees
from using the drains to dispose of oil, other vehicle fluids,
solvent, paint or similar liquids. Review these rules with your
employees.
- Use only non-toxic soaps to clean
floors and vehicles instead of hazardous materials.
- If you have floor drains at your
facility that are not in use, consider having them capped or plugged
to prevent misuse or accidental discharges.
- Prevent drips and spills from
reaching the floor.
- Check your floor drains and make
certain you know where they discharge.
- Setup and use a maintenance schedule
for inspection and cleaning of floor drains, oil/water separators,
traps, etc.
- Never have floor drains where
hazardous materials are stored.
- If your wastewater is nonhazardous,
you may want to purchase evaporating equipment to evaporate your
wastewater. It should be noted that evaporators may require an
air permit or registration, and evaporator bottoms may be considered
a hazardous waste.
- Don’t use degreaser solvents to
clean engines. Most engine degreasers are hazardous and should
not be discharged to a POTW. Even if you use nonhazardous degreasers,
the oil and grease concentration in the spent degreaser may exceed
the limit allowed by your sewer authority.
