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
There is a simple
rule for determining when it is OK to put industrial wastewater
into a septic system - never. You can dispose of "sanitary
wastes" from ordinary lavatory use or hand washing in a septic
field only if the wastewater has not been contaminated with
any water from an industrial operation.
Some yards may
have shallow wells or cesspools that have been used for disposal
of industrial wastewater. It is now illegal to create such
systems, and existing systems need to be sealed or closed.
This fact sheet will help you check whether your existing wastewater
disposal practices are in compliance with current rules.
Regulations
This fact sheet
explains the regulations applicable to septic tanks or other forms
of disposal wells used at auto recycling facilities for disposal
of vehicle fluids or industrial wastewater. These methods of disposal
are referred to as "motor vehicle waste disposal wells."
They are regulated under federal and state Underground Injection
Control (UIC) regulations that protect drinking water supplies.
Motor vehicle
waste disposal wells are floor drains or sinks in service bays that
are tied into a shallow disposal system. Most commonly, these shallow
disposal systems are septic systems or dry wells, but any underground
system that receives motor vehicle waste would be considered a motor
vehicle waste disposal well. A variety of names are used to describe
shallow disposal systems including: cesspools, catch basins, sink
holes, underground vaults, or drain tanks, to name a few.
Automotive recyclers
must adhere to the following federal rules for motor vehicle waste
disposal wells:
- New motor vehicle waste disposal wells are banned nationwide
as of April 5, 2000.
- Existing motor vehicle waste disposal wells are banned
in ground water protection areas and other sensitive ground water
areas.
*In short, spent
parts washer cleaners, both solvents and aqueous cleaners, and other
types of industrial wastewater should never be discharged to a septic
system.
The only permissible
use for septic systems is disposal of sanitary sewage, which includes the water coming from lavatories/washrooms,
showers, drinking fountains, etc.

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 septic tank or underground well.
- Does your facility discharge vehicle fluids or
related industrial wastewater to a septic tank or similar system?
Does a permit authorize the discharges? 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 wastewater discharges. Use of a septic tank
or similar system is not a viable option.
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
septic tank management.
- Check your sinks and floor drains in the shop to make
certain you know where they discharge.
- Cap or plug any floor drains connected to a septic tank.
- Do not put other fluids like oil, solvents, paints or
chemicals into a floor drain. This could contaminate your property
and expose you to large fines and clean up costs.
- Think about installing an emergency shut-off on the
drain pipes to prevent accidental spills from entering the sewer.
- Train employees on the importance of preventing any
vehicle fluids or other industrial wastes from entering a septic
tank or well.
- Post signs at sinks connected to your septic tank system
to remind employees not to discard any wastes into the sink.
Contacts
