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
Floor drains, especially those built
when designers and contractors were much less environmentally conscious
than they are now, can be full of surprises. If you do not
know what is happening at the other end of yours, you would be well
advised to find out before an inspector does.
Floor drains in many industrial facilities
have been found to empty into surface waters, or into septic fields.
In either case, the discharge of wastewater from the shop floor
into this kind of system is almost certainly illegal. If the
floor drain discharges into a city sewer system, it will need a
permit, and will need to be periodically monitored. Floor
drains can also leak, and have been known to cause serious and costly
soil and groundwater contamination problems. This fact sheet
will help you determine if the floor drains in your facility are
properly connected and properly used.
Regulations
This fact sheet addresses regulatory
issues and practices associated with floor drain systems. A floor
drain system commonly includes a concrete trench, which runs down
the center of a shop floor that may lead to underground pipes and/or
tanks. Instead of a trench, some shops have single or multiple rectangular
or round floor drains. Typically, the shops floor is slightly sloped
to allow liquids to flow into the floor drain.
A floor drain is a red flag for any
inspector from an environmental protection agency. Their concerns
are primarily:
- What types of materials could
potentially enter the floor drain system, and
- What ultimately happens to those
materials?
It is very important to know where
all your floor drains lead, and are aware of Ohio EPA’s regulations
that apply to your discharge activities. If you do not know where
your drains lead, or if you using floor drains improperly, you could
be contaminating nearby surface waters or drinking waters.
Some floor drains lead into a sanitary
sewer, where wastewater goes directly to a public wastewater treatment
plant (POTW) from Ohio EPA. Other floor drains lead to an on-site
sewage treatment system like a septic tank. Sometimes floor drains
lead directly to an underground holding tank or discharge to a waterway
or to the ground outside. Ohio EPA’s water pollution control regulations
apply to all of these activities.
Any company that wants to discharge
an industrial wastewater to waters of the state need to get a permit
(NPDES permit) from Ohio EPA. Examples of waters of the state include
streams, rivers, lakes, ponds, marshes, waterways, wells and springs.
If your floor drains lead to any water of the state, you must have
a discharge permit for this activity.
Companies that discharge industrial
wastewater directly to a POTW are also regulated. Often, the POTW
regulates the discharge activities. If you are discharging to a
POTW, you need to contact them and discuss your activities with
them. You may be required to obtain a permit for the discharge.
In addition, you may be required to treat the wastewater before
discharging (e.g. oil/water separation, removing solids, chemicals,
etc.)
Note: It is illegal to discharge
process wastewater outside your business onto the ground. Make sure
your floor drains don’t lead outside where wastewater could end
up on the ground.

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
floor drain system.
- Do your floor drains discharge
to the ground, a water body or storm sewer? Are the discharges
authorized by a permit? Make sure your floor drains DO NOT
discharge industrial wastewater onto the ground. This discharge
activity is illegal and you must find another way to manage the
wastewater. If you are using floor drains to discharge industrial
wastewater to a water body you must have a National Pollutant
Discharge Elimination System (NPDES) Permit. This includes discharges
into storm sewers.
- Do your floor drains discharge
to a city sewer system? Are the discharges authorized by a permit?
If you are using floor drains to discharge wastewater to a local
wastewater treatment plant, make sure the treatment plant knows
about this activity. You may be required to conduct treatment
on the wastewater before discharging it. You also need to get
a permit or written notification for the discharge.
- Is oil or solvent discharged
to floor drains? These are RCRA regulated wastes and must
be removed and properly disposed of. If the floor drain system
is connected to the city sewer system, Federal and state laws
prohibit the discharge of oil or flammable solvents.
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 floor drains.
- Check all of your floor drains
and make sure you know where they drain.
- Cap or plug floor drains that
are not serving a useful and lawful purpose.
- Use drip pans or similar devices
to collect vehicle fluids before they reach the floor drain system.
- Do not put fluids like oil, solvents,
paints or chemicals into a floor drain.
- Install berms in the shop around
areas where chemicals are stored to prevent their entry into the
floor drain system.
- Install screens in drains to prevent
solids from entering the floor drain system.
- Develop and implement a maintenance
schedule for inspecting and cleaning the floor drain system.
- Prepare and train for emergencies.
Have a plan in place to quickly cleanup a spill before it escapes.
- Use dry cleaning methods such
as sweeping instead of water cleanup, whenever possible.
- Don’t hose down your work area.
This practice generates large quantities of contaminated wash
water.
- Consider sealing your shop floor
with epoxy or other suitable sealant.
