NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES)
WHAT IS NPDES? NPDES is a federal mandate that prohibits pollutants from entering the storm drain system.
NPDES Stormwater (MS4) Permit - Issued in 2001 by the California Regional Water Quality Control Board (CRWQCB) under Order No. 01-182, NPDES No. CAS004001, the permit covers an area of approximately 3,100 square miles and serves a population of about 10 million (2000 census). The County of Los Angeles and 84 incorporated cities are the listed permittees. Pursuant to Clean Water Act amended 1987, the EPA established regulations setting forth NPDES requirements for stormwater discharge. This mandate requires all public agencies to implement programs and activities that reduce the discharge of pollutants found in stormwaterf rom entering U.S. Waters.
The Public Works Department and the Community Development Department have both assigned staff to make sure the City is in compliance with the NPDES permit. Public Works handles the inter-agency liaisons, capital improvement projects relative to permit compliance and the input for the new NPDES Permit. Community Development handles the site inspections, development plan checks, public education programs and administration. Currently the Public Works Department has two projects proposed for permit compliance; one is to construct a clarifier to send waste water from our street sweepers to the sewer and the second is to hire a contractor to video inspect all our storm drains that are 36 inches in diameter or greater.
In summary, the City is required to perform:
- Construction. Industrial/Commercial inspection and enforcement.
- Inspection of Storm Drain Channels/Pipes 36 inches and larger.
- Prioritizing Catch Basins and more frequent clean outs Installation of trash receptacles at all transit stops.
- Bi-monthly cleaning of City owned parking lots.
- Additional Record Keeping and Reporting.
- Employee Training.
- Public Outreach
What can you do?
Don't Litter: Everything dropped, tossed, spilled or discarded onto streets and gutters will eventually make its way into the storm drain system--and out to the ocean!
Report Illegal Dumping: Illegal dumping of trash, paint products, motor oil and other chemicals into storm drains is against the law!
Pick up after your Pets: Animal waste that runs off of lawns and sidewalks sends harmful bacteria into the storm drain system and out into the ocean, creating problems for swimmers and fish.
Take your hazardous Waste Materias to a S.A.F.E. Center: Residential Special Materials are typical household products that should not be disposed of by merely throwing in the trash. These items include unused or leftover paint, pesticides, cleaners and other chemicals.
