What is
Stormwater Runoff.?
When rain falls, water runs off all impervious surfaces, such as
streets and parking lots. The rain water picks up any
contaminants in its path and eventually finds its way into a storm
drain. This water is called stormwater runoff.
Stormwater runoff contains many pollutants, including motor oil,
fuel, pesticides and fertilizers, detergents, solvents, antifreeze,
trash, disease -causing bacteria, pet waste, construction waste
and litter.
The pollutants picked up by the stormwater flow untreated
directly through the storm drainage system into the nearest lake,
river or creek. Storm drains are NOT part of the sanitary sewer
system that treats wastewater from buildings.
The contaminants in stormwater can kill aquatic life. And they
pollute the rivers and lakes that provide our drinking water,
making it more expensive to make the water safe for human use.
To protect our water, the Clean Water Act of 1972 prohibits the
discharge of pollutants into water. The goal of Municipal Good
Housekeeping and Pollution Prevention is to improve and protect
the quality of receiving waters.
In addition to following these best management
practices, you have another important role in
fighting stormwater pollution...
Detection!
City employees who work around town are in an excellent
position to watch for possible illicit discharges to the storm
sewer system.
❑ Look for a plastic pipe or hose in a storm drain.
❑ Staining around a storm drain indicates that someone
dumped something in it.
❑ Contractors and shop owners hosing down equipment
probably don't realize they're damaging water quality -
and, breaking the law.
❑ Remember, nothing but rain belongs in the storm drain.
So, please, do your part. Report illegal dumping and
discharges.
❑ Call 336-727-8000 to report polluters.
❑ Each city employee has a responsibility to comply with the
legal requirements to prevent stormwater pollution. Follow
the best management practices you've learned today, and
you'll be in good shape.

Landscaping Best Management Practices

pollution.

directions.'
❑ Do not apply any chemical before,
during, or immediately after rain
unless directed by the manufacturer.
spot spraying
❑ Spot spraying of pesticides is better than broadcast spraying.
❑ Define chemical -free buffers around streams and lakes.
❑ If granular material gets on a paved area, sweep it up or blow
it back into the grass. The same applies to grass clippings.
❑ Never dump clippings in a drainage ditch or storm drain,
where they can be carried away by runoff.
A BMP can include a structure, equipment or some other device,
or a way of doing things - such as cleaning up spills - that
reduces stormwater pollution.
Two types of BMPs
Structural BMPs refer to
something physical, such as a
piece of equipment, a holding
pond for stormwater, or a roof
over a vehicle maintenance area.
Non-structural BMPs, sometimes
called Operational BMPs, deal with
how we do our jobs. They range
from how we wash our vehicles,
to how we store and apply fertilizer
and pesticides, to how we repair
city streets.
A non-structural BMP could
include checking to make sure
that materials are stored
properly (e.g. off the ground,
covered, and no leaks or spills).

Vehicle & Equipment Cleaning
❑ Wash vehicles or other equipment where wastewater is
contained.
❑ A washing area with a roof over it (such as the washing shed
in the City Yard) prevents rain from falling into the wash area.
❑ Do not wash or steam -clean vehicles or equipment where
wastewater is not contained.
❑ Waste water contains many contaminates, including heavy
metals, rust, and oil & grease that can run off into the nearest
storm drain.
❑ Vehicle and equipment maintenance involves many materials
that pollute stormwater: fuel, lubricants, paints, hydraulic fluid,
solvents, antifreeze, battery acid and more.
❑ Do your maintenance where materials will not be exposed to
stormwater, preferably indoors.
❑ Rain water can wash automotive fluids, rust and other toxic
substances into the storm drain.
❑ If you must leave a vehicle outside for maintenance, make
sure all nearby storm drains have been blocked off and
protected from automotive fluids.
❑ Leaking vehicles are particularly hazardous. Move the vehicle
indoors, or drain the leaking fluid.
❑ Clean up any fluid that has leaked out using a dry clean up method.
❑ If you can't get to it right away, or if you're in the field, place a
drip pan under the leak until you can get it indoors. Drip pans
are a very simple and very effective BMP.
❑ Dump fluids from the drip pan into a recycle drum.
Outdoor Storage
❑ When storing materials, it's important to remember that any
materials or waste stored outdoors can contaminate.
❑ Rainfall can wash off ink, oils, food scraps and debris from
dumpsters and garbage bins.
❑ Keep dumpsters covered at all times. Use a tarp if necessary.
❑ Never put liquids into dumpsters. Dumpsters are not
watertight and liquids will leak out.
❑ Install dumpster plugs, and replace dumpsters with rusted
bottoms.
❑ Storage tanks often have secondary containment, but can
pose a problem. The containment area may have a valve to
drain rain water. This valve must be kept closed at all times,
except when draining rainwater. When you do use the valve,
be sure the accumulated rainwater is clean and
uncontaminated.
❑ Portable containers such as buckets, pails or bagged
materials should never be stored for long periods outdoors,
unless the container is made for outdoor storage.
❑ If materials must be stored outside, cover them with a water
proof tarp.

Street Maintenance
❑ Street sweeping is the preferred BMP for removing leaves,
grass, dirt, cigarette butts, litter and anything else in the gutter.
❑ Never sweep debris into a storm drain or a drainage ditch.
❑ Do not saw or cut pavement before or during rain.
❑ Take care to keep waste from getting into gutters or storm
drains.
❑ Protect storm drains nearby.
❑ Clean up debris and
dispose of it properly.
❑ Catch basins should be
inspected annually to
determine if they need to
be cleaned.
❑ An organized record
keeping system should be
used to schedule and
document inspections.

Spills
❑ Many spills occur while fueling vehicles and equipment.
❑ Keep the nozzle securely in the pipe.
❑ Stay with the vehicle while fueling to make sure it all goes in
the tank.
❑ Never top off the tank.
❑ The cardinal rule is: NEVER hose down a spill.
❑ If possible, clean up spills right away. Salt, fertilizer, hydraulic
oils and lubricants usually can be cleaned up easily.
❑ Use dry clean up. Sweep up granular materials. If liquid, use
absorbents and sweep them up.
❑ If the spill involves hazardous material, you will have to get
help. Call your supervisor, then dial 911 and request the
Hazardous Materials Response team.

Housekeeping
❑ Good housekeeping maintains a clean
and orderly work environment. This
reduces the possibility of accidental
spills and other safety hazards. Also,
well maintained material and chemical
storage areas reduce the possibility of
stormwater mixing with pollutants.
❑ To practice good housekeeping,
maintain dry and clean floors and
ground surfaces.
clean ground surfaces
❑ Pickup and dispose of garbage and waste material regularly.
❑ Inspect for leaks or contact of stormwater with raw materials,
waste materials, or products routinely.
❑ Identify and label all drums and containers.
❑ Vacuum and/or sweep up daily.
❑ Use a drop cloth or tarps under work that produces overspray
or debris.
❑ Clean up all spills promptly.
❑ Secure drums and containers and check frequently for leaks
and spills.
❑ Store containers and drums away from direct traffic routes to
prevent accidental spills.
❑ Properly dispose of waste.
❑ Keep work materials organized.
❑ NEVER hose off an outdoor work area The water will wash
waste products and toxic substances into a storm drain.
❑ Spills are a constant, major threat, because anything that falls
on the ground can be picked up by stormwater.
❑ A checklist of regular housekeeping activities is a very
effective BMP... if you use it.
❑ Good housekeeping is especially important if you work with
toxic or hazardous materials.
❑ Identify all toxic and hazardous substances that are stored or
handled on site.
❑ Have written procedures for the handling of toxic and
hazardous substances.
❑ The first step in spill prevention is to identify potential spill
areas and where those areas drain.
❑ Common spill locations include loading and unloading areas,
storage areas, maintenance and processing areas, fueling
stations, and waste disposal areas.
❑ Effective spill response includes knowing where the spill kit
for cleaning up spills is located.
❑ Your department or division
should have a stormwater spill
prevention plan, tailored to its
specific activities, and you
should be trained on how to
implement it.
