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 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 the New Jersey Department
of Environmental Protection’s (DEP) 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 sewer system or treatment
plant. Sometimes floor drains lead directly to an underground holding
tank or discharge to a waterway or to the ground outside. DEP’s
water pollution control regulations apply to all of these activities.
If you want to discharge industrial
wastewater to waters of the state, you must have a New Jersey Pollutant
Discharge Elimination System (NJPDES) permit from DEP. 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 sewer system or treatment plant are also
regulated. Check with DEP’s Division of Water Quality or your local
sewer authority to determine whether you need a permit. 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 into a septic tank or dry
well. See the ECAR
Septic Tanks 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
floor drain system.
- Do your floor drains discharge
to the ground, a water body or storm sewer? Are the discharges
authorized by a permit? If you are using floor drains to discharge
industrial wastewater to a water body you must have a New Jersey
Pollutant Discharge Elimination System (NJPDES) Permit. This includes
discharges into storm sewers. In some areas of the state, such
as those over sole source aquifers, discharge to ground may not
be allowed or may require further controls.
- 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 may 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.
- Is your floor drain connected
to a septic tank or dry well? If so, you are in violation
of state law. All septic tanks and dry wells must be sealed or
closed.
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.
