Storm Water Management

Storm water runoff is rain water that travels over roadways and rooftops to catch basins without absorbing into the ground. The water is not treated and goes directly into Merced County's waterways. Along the way, it picks up pollutants such as motor oil, antifreeze, paints, pet waste, car wash water, pesticides, herbicides and fertilizers. Best Management Practices (BMPs) are practiced to stop pollutants from entering Merced County's waterways.

The Federal Clean Water Act was enacted in 1972 to make the discharge of pollutants to any waterbody in the United States unlawful. On April, 30, 2003, the State Water Resources Control Board (SWRCB) elected to enact the SWRCB Water Quality Order No. 2003-0005-DWQ to enforce that. Under the SWRCB Water Quality Order No. 2003-0005-DWQ, Merced County was tasked with creating a Storm Water Management Plan that outlines the BMPs to achieve the removal of pollutants from storm water to the maximum extent possible. The BMPs are delineated in the following six control measures (1) public education and outreach on storm water impact program, (2) public involvement / participation program, (3) illicit discharge detection and elimination program, (4) construction site storm water runoff control program, (5) post-construction storm water management in new development and redevelopment program, and (6) pollution prevention/ good housekeeping for municipal operations.

As of February 5, 2013, the SWRCB adopted SWRCB Water Quality Order No. 2013-0001-DWQ to modify the existing SQRCB Water Quality Order No. 2003-0005-DWQ. Ordinance No. 1923: Stormwater Ordinance was enacted by Merced County to carry out the enforcement measures found in the SWRCB Order No. 2013-0001-DWQ.
