Stormwater pollution is caused by stormwater runoff from streets, parking lots, sidewalks, rooftops, construction sites, and other surfaces. Pollutants such as sediment, oils, chemicals, trash, and other materials are carried by the rain into the storm sewer system and directly into our lakes, streams, and the ocean. Stormwater is untreated, that is, it does not go to a wastewater treatment plant.
The U.S. Environmental Protection Agency National Pollutant Discharge Elimination System (EPA NPDES) Phase II Final Rules require that the county implement a Stormwater Management Program (SWMP).
The Central Coast Regional Water Quality Control Board (RWQCB) receives the County’s Annual Report that itemizes the different things we are doing to implement our program and protect the water quality of the creeks and ocean.
Most people are surprised to learn that storm water is the leading cause of water pollution in the nation. Storm water is rain that runs off streets, parking lots, sidewalks, rooftops, construction sites and other surfaces. Rain water goes down the storm drains placed in the streets and then flows into creeks or directly into the ocean through a system of pipes. Rain water is NOT treated before it enters the creeks or ocean; whatever material the water collects as it runs off the streets, parking lots, your property, or construction site, ends up in the creek or ocean.
Pollutants such as oil, trash, litter, animal waste, chemicals and other materials are carried by the rain into the storm drain system. Anything we can do to keep the storm water clean will improve the water quality of our creeks, lakes and ocean. Only rain should go down the drain!
