Wash water from vehicle and equipment cleaning activities performed outdoors or in
areas where wash water flows onto the ground can contribute toxic hydrocarbons and
other organic compounds, oils and greases, nutrients, phosphates, heavy metals, and
suspended solids to stormwater runoff. Use of practices can prevent or reduce the
discharge of pollutants to stormwater during vehicle and equipment cleaning.
`practices
General
- Use biodegradable, phosphate -free detergents for washing vehicles as
appropriate.
- Provide a trash container in a wash area.
- Map on -site storm drain locations to avoid discharges to the storm drain system
Vehicle and Equipment Cleaning
When engine cleaning is conducted and when chemical additives, solvents, or
degreasers are used design wash areas to allow wash water to be absorbed into
the ground and not runoff into other areas. This may include grading of the area
to collect wash water as well as prevent stormwater run-off.
Washing on -side and outdoor:
- Use designated wash areas. Designated wash areas must be marked.
- Oil changes and other engine maintenance cannot be conducted in the
designated washing area. Perform these activities in a place designated for
such activities.
Use hoses with nozzles that automatically turn off when left unattended.
- Id don on -site, no pressure cleaning and steam cleaning should be done in areas
designated as wellhead protection areas for public water supply.
Training
- Train employees on proper cleaning and wash water disposal procedures and
conduct "refresher" courses on a regular basis.
- Train staff on proper maintenance measures for the wash area.
- Train employees and contractors on proper spill containment and cleanup. The
employee should have tools and knowledge to immediately begin cleaning up a
spill if one should occur.

Vehicle and Equipment Maintenance and Repair
Description
Vehicle or equipment maintenance and repair is potentially a significant source of
stormwater pollution due to the use of materials and wastes created that are harmful to
humans and the environment. Engine repair and service (e.g., parts, cleaning),
replacement of fluids (e.g. oil change), and outdoor equipment storage and parking
(dripping engines) can impact water quality if stormwater runoff from areas with these
activities occurring on them becomes polluted by a variety of contaminants.
Implementation of the following activities will prevent or reduce the discharge of
pollutants to stormwater from vehicle and equipment maintenance and repair activities).
Practice
Pollution Prevention
- Keep maintenance schedule to evaluate materials use.
- Keep an inventory of materials
- Recycle used motor oil, diesel oil, and other vehicle fluids, and parts whenever
possible.
General
- Move maintenance and repair activities indoors whenever feasible.
- Store idle equipment containing fluids under cover whenever feasible.
- Use a vehicle maintenance area designed to prevent stormwater pollution —
minimize contact of stormwater with outside operations through appropriate
drainage routing.
- Avoid hosing down your work areas.
- Post signs at sinks to remind employees, not to pour hazardous wastes down
drains.
- Clean yard storm drain inlet(s) regularly.
- Do not pour materials down drains or hose down work areas; use dry sweeping.
- Cover the work area to limit exposure to the rain.
Material and Waste Handling
- Store materials and wastes under cover whenever possible.
- Designate a special area to drain and replace motor oil, coolant, and other fluids.
This area should not have any connections to the storm drain or the sanitary sewer
and should allow for easy clean up of drips and spills.
- Drain all fluids from wrecked vehicles immediately. Ensure that the drain pan
or drip pan is large enough to contain drained fluids (e.g. larger pans are
needed to contain antifreeze, which may gush from some vehicles).
Do not pour liquid waste to floor drains, sinks, outdoor storm drain inlets, or
other storm drains or sewer connections.

Do not dispose of used or leftover cleaning solutions, solvents, and
automotive fluids and oil in the sanitary sewer.
Dispose of all waste materials according to applicable laws and regulations.
Collect leaking or dripping fluids in drip pans or containers. Fluids are easier
to recycle if kept separate.
- Promptly transfer used fluids to the proper waste or recycling drums and
store in an appropriately designed area that contain spills. Don't leave drip
pans or other open containers lying around.
Do not dispose of oil filters in trash cans or dumpsters, which may leak oil
and contaminate stormwater. Place the oil filter in a funnel over waste oil
recycling drum to drain excess oil before disposal. Most municipalities
prohibit or discourage disposal of these items in solid waste facilities. Oil
filters can also be recycled. Ask your oil supplier or recycler about recycling
oil filters.
- Store cracked and/or dead batteries in a non -leaking covered secondary
container and dispose of properly at recycling or household hazardous
waste facilities.
Maintenance and Repair Activities
- Provide a designated area for vehicle maintenance
- Keep equipment clean, don't allow excessive build-up of oil and grease.
- If temporary work is being conducted outside: Use a tarp, ground cloth, or
drip pans beneath the vehicle or equipment to capture all spills and drips;
The collected drips and spills must be disposed, reused, or recycled
properly.
ehicle fluid removal or changing inside or under
If possible, perform all v
cover to prevent the run-on of stormwater and the runoff of spills:
Keep a drip pan under the vehicle while you unclip hoses, unscrew filters,
or remove other parts. Ise a drip pan under any vehicle that might leak
while you work on it to keep splatters or drips off the shop floor.
Promptly transfer used fluids to the proper waste or recycling drums.
Don't leave drip pans or other open containers lying around.
Keep drip pans or containers under vehicles or equipment that might drip
during repairs.
Do not change motor oil or perform equipment maintenance in non -
appropriate areas.
If equipment (e.g. radiators, axles) is to be stored outdoors, oil and other
fluids should be drained first. This is also applicable to vehicles being
stored and not used on a regular basis.

Monitor parked vehicles closely for leaks and place pans under any leaks
to collect the fluids for proper disposal or recycling.
Inspection
- Regularly inspect vehicles and equipment for leaks, and repair
immediately.
- Make sure incoming vehicles are checked for leaking oil and fluids. Apply
controls accordingly.
Training
- Train employees and contractors in the proper handling and disposal of
engine fluids and waste materials
- Ensure that employees are familiar with the site's spill control plan and/or
proper spill cleanup procedures (You can use reusable cloth rags to clean
up small drips and spills instead of disposables; there can be washed by a
permitted industrial laundry. Do not clean them at home immediately or at
a coin -operated laundry business). The employee should have the tools
and knowledge to immediately begin cleaning up a spill if one should
occur.
- Use a training log or similar method to document training.
