One of the most common types of pollution from businesses is contaminated
water runoff, usually from cleaning and maintenance activities.
Simple best management practices (BMPs) can prevent stormwater pollution,
and prevention is good business. It means clean water, clean beaches
and shows your customers you care about the community.

 RESTAURANTS
Food waste, grease, cleaning solvents, mop water and trash from
restaurant operations often make their way into the Orange County
storm drain system, polluting local waterways. Follow these best
management practices to prevent pollution and protect the environment.
Cleaning:
- Clean floormats, filters and garbage cans in a mop sink, floor
drain or proper outside area, not the parking lot, alley, sidewalk
or street.
- Pour washwater into a janitorial or mop sink, not outside in
the parking lot, alley, sidewalk or street.
- Use non-toxic cleaning products.
Grease & hazardous materials:
- Recycle grease and oil, instead of pouring it into sinks, floor
drains or into a parking lot or the street.
- Dispose of all unwanted tactic materials like cleaning products
through a hazardous waste hauler. These items are not trash.
Spills:
- Use dry methods for spill cleanup, by sweeping and using cat
litter instead of hosing.
- Have spill containment and cleanup kits available for possible
spills on your property. To report serious toxic spills, call
911.
Outside maintenance:
- Keep dumpster lids closed and the areas around them clean. Do
not fill with liquid waste or hose them out. Call your trash hauler
to replace any dumpsters that leak.
- Sweep outside areas regularly and put the debris in the garbage,
instead of sweeping or hosing it into the parking lot or the street.

AUTOMOTIVE
SERVICES
Motor oil, anti-freeze, grease and other toxic fluids from auto
repair and gas station operations often make their way into the
Orange County storm drain system, and flow untreated into local
waterways. Follow these best management practices to prevent pollution
and avoid fines and legal action.
Preventing leaks and managing spills:
- Use drip pans to catch leaks when pouring and draining fluids.
- Prevent leaks from stored vehicles by draining gas, hydraulic
oil and transmission, brake and radiator fluids.
- In case of a hazardous spill, follow your hazardous materials
response plan as filed with your local fire department or other
hazardous materials authority.
- Be sure employees are familiar with your hazardous materials
response plan and are capable of implementing it.
Storing and disposing of hazardous materials:
- Keep liquid wastes segregated. Many fluids can be recycled through
hazardous waste disposal companies, as long as they are not mixed.
- Store hazardous materials under cover or inside, to prevent
leaks and spills.
- Recycle motor oil, oil filters, antifreeze, batteries, solvents,
lubricants, tires and metal filings from grinding and polishing
metal parts. These items are not trash, and are illegal to dump.
Contact a hazardous waste hauler for proper disposal.
Cleaning and maintenance:
- Use dry methods, by sweeping and using absorbent cleaning agents,
to clean work areas, instead of hosing them down.
- Sweep outside areas regularly and put the debris in the garbage,
instead of sweeping or hosing it into the street.
- Keep dumpster lids closed and the areas around them clean. Do
not fill with liquid waste or hose them out. Call your trash hauler
to replace any dumpsters that leak.
Washing vehicles:
- Wash vehicles at a washing facility that reclaims water. If
washed at your business, use berms or sweep to keep contaminated
wash water from flowing into the street.
- Use nontoxic detergents and cleaners.

CONSTRUCTION
AND DEVELOPMENT
Soil, cement wash, asphalt and oil from construction sites
often make their way into the Orange County storm drain system,
and flow untreated into local waterways. Follow these best management
practices to prevent pollution and avoid fines and legal action.
Erosion prevention:
- Reduce erosion by avoiding excavation or grading activities
during wet weather, and by planting temporary vegetation on slopes
where construction is not immediately planned.
- Use berms and diversion dikes to channel and contain runoff.
Concrete and mortar application:
- Prevent mortar and cement from entering storm drains by placing
erosion controls such as berms or temporary vegetation down-slope
to capture runoff.
- Wash concrete mixers and equipment only in specified wash-out
areas, where the water flows into containment ponds. Cement wash
water can be recycled by pumping it back into cement mixers for
reuse.
- Never dispose of cement washout into driveways, streets, gutters
or drainage ditches.
Handling materials and waste:
- Cover exposed piles or bags of soil, cement and other construction
materials with plastic sheeting to prevent it from blowing or
washing into the storm drain system.
- Recycle broken asphalt, concrete, wood and cleared vegetation.
- Store hazardous materials under cover or inside, to prevent
leaks and spills.
- Dispose of hazardous materials through a hazardous waste hauler
or other means in accordance with the construction permit.
Managing spills:
- In case of a hazardous spill, follow your hazardous materials
response plan as filed with your local fire department or other
hazardous materials authority.
Equipment maintenance:
- Inspect vehicles and equipment frequently for leaks.
- Perform major equipment repairs and washing off site.
- Use gravel approaches where truck traffic is frequent to reduce
soil compaction and limit the tracking of sediment into the streets.
COMMERCIAL
LANDSCAPE MAINTENANCE
Keeping lawns and gardens looking good isn't always good for our
environment. Sprinkler runoff carries pesticides and fertilizers
into the storm drain system. Leaves, grass clippings and yard waste
get swept or blown into the street, along with sediment from erosion,
clogging catch basins and polluting waterways. Follow these best
management practices to prevent pollution and avoid fines and legal
action.
Yard waste:
- Recycle leaves, grass clippings and other yard waste, instead
of blowing, sweeping or hosing them into the street or gutter.
- Let your customers know about grasscycling. Let grass clippings
drop on the lawn, instead of using a grass catcher. The clippings
act as a natural fertilizer, returning nutrients and organic matter
back to the soil, and because grass is mostly water, it also irrigates
lawns, conserving water. Reducing the need to water as often or
use toxic fertilizers means less contaminated runoff.
Erosion prevention:
- Prevent erosion and sediment runoff by using berms and vegetation
down-slope to capture runoff.
- Cover exposed piles or bags of soil, groundcover and other materials
with plastic sheeting to prevent it from blowing or washing into
the storm drain system.
Pesticides and fertilizers:
- Spot apply pesticides, rather than blanketing entire areas.
- Ask you customers if they prefer nontoxic alternatives to traditional
pesticides and fertilizers.
- Do not put pesticides or fertilizers in the trash. Dispose of
hazardous materials through a hazardous waste hauler or take them
to a household hazardous waste collection site to be recycled.
Wise water use:
- Control the amount of water and direction of sprinklers, to
avoid waste and runoff.
- Periodically inspect and fix leaks and misdirected sprinklers.
