Car Maintenance Problems

Many common car maintenance routines contribute to ocean pollution. Washing the car or pouring used motor oil into a gutter or storm drain pollutes the ocean. Water runoff from streets, parking lots and driveways picks up oil and grease dripped from cars, asbestos worn from brake linings, zinc from tires and organic compounds and metals from spilled fuels. These chemicals drain into the ocean, harming sea life.
Oil and grease, for example, clog fish gills and block oxygen from entering the water.
If oxygen levels in the water become too low, aquatic animals die.

1. Cleaning Work Sites

Do not hose down your shop floor. It is best to sweep regularly. For information about proper disposal of industrial waste, call the City of Los Angeles, Integrated Solid Waste Management Office (213) 237-1444
Use nontoxic cleaning products. Baking soda paste works well on battery heads, cable clamps and chrome; mix the soda with a mild, biodegradable dishwashing soap to clean wheels and tires; for windows, mix white vinegar or lemon juice with water.

2. Spills

Prepare and use easy to find spill containment and cleanup kits. Include safety equipment and cleanup materials appropriate to the type and quantity of materials that could spill.

Pour kitty litter, sawdust or cornmeal on spills. For disposal instructions, call the: City of Los Angeles Hazardous and Toxic Materials Office
(213) 237-1209

3. Fluids

Your customer’s regular car maintenance prevents fluids from leaking onto streets and washing into storm drains.
It is also good for business.
Change fluids carefully. Use a drip pan to avoid spills.
Prevent fluid leaks from stored vehicles. Drain fluids such as unused gas, transmission and hydraulic oil, brake and radiator fluid from vehicles or parts kept in storage.
Implement simple work practices to reduce the chance of spills. Use a funnel when pouring liquids (like lubricants or motor oil) and place a tray underneath to catch spills. Place drip pans under the spouts of liquid storage containers. Clean up spills immediately.

4. Washing Vehicles

Prevent oil and grease, suspended solids and toxins from washing into storm drains:

Designate a washing site where water drains to the sewer system. The area must be paved and well marked as a wash area. Post signs prohibiting oil changes and washing with solvents. Train all employees to use the designated area.

Wash vehicles with biodegradable, phosphate-free detergent. Use a bucket (not a running hose) to wash and rinse vehicles. This conserves water and minimizes urban runoff.
