National Pollution Discharge Elimination Systems (NPDES)
Unlike the sewer system, which carries wastewater from your home to treatment plants, the storm drain system in Chino releases untreated water into flood control channels, creeks, and rivers. Anything that gets thrown, swept or poured into the street, gutter or a catch basin will lead into our local waterways. This includes paints, fertilizers, pesticides, motor oil, pet waste, trash, sewage, pool filter media, construction waste, sediment, degreasers and chemicals. Storm water pollution from urban runoff is a public health risk and an environmental threat to the quality of our local waterways. To report illegal dumping into the City of Chino's streets or storm drains and to report clogged storm drains, please call the Chino Police Department at (909) 334-3000 during business hours and (909) 628-1234 all other hours.
On January 10, 2010 the Santa Ana Regional Water Quality Control Board (SARWQCB) adopted Order No. R8-2010-0036 . This order renewed the National Pollution Discharge Elimination System (NPDES) Municipal Storm Water Permit for San Bernardino County.
Water Quality Management Plans (WQMPs)
The WQMP is intended to provide information related to the project's generation and mitigation of water quality pollutants and assessment of hydrological impacts. The WQMP contains project information related to site characteristics, expected pollutants, and hydrology impacts. It describes the incorporation of Low Impact Development (LID) Preventative measures as well as LID Mitigative Measures listed here in order of priority: (1) infiltration Best Management Practices (BMPs); (2) BMPs that harvest and use runoff; and (3) vegetated BMPs that promote evotranspiration. The collective information is intended to describe how the project will minimize water quality impacts to downstream water bodies.
The City implements a comprehensive project review and approval process to ensure that proposed projects comply with the MS4 Permit and local ordinance requirements. All priority projects are required to submit a Preliminary WQMP for review by the Public Works Water and Environmental Engineering Department. Projects classified as Non-Priority per the WQMP Technical Guidance document (TGD) must consult with the city staff to discuss WQMP submittal requirements and selection of LID Preventative Measures.
