Stormwater Discharges from Construction Activities
Stormwater runoff from construction activities can have a significant impact on water quality. As stormwater flows over construction sites, it picks up pollutants, debris, and chemicals. These are then transported, untreated, to our rivers, creeks, and sloughs, and eventually to the Delta. Polluted runoff can harm or kill fish and other wildlife, destroy aquatic habitat, or cause stream bank erosion.
The National Pollutant Discharge Elimination System (NPDES) stormwater program requires construction site operators engaged in clearing, grading, and excavating activities that disturb one or more acres, including smaller sites in a larger common plan of development or sale, to obtain coverage under an NPDES permit for their stormwater discharges.
Stormwater Discharges from Industrial Facilities
Industrial activities that take place at industrial facilities are often exposed to the weather and generate runoff that contains residual pollutants from the industrial site. This runoff is then transported, untreated, to our rivers, creeks, and sloughs, and eventually to the Delta. To minimize the impact of stormwater discharges from industrial facilities, the NPDES program includes an industrial stormwater permitting component that covers 10 categories of industrial activity that require authorization under an NPDES industrial stormwater permit for stormwater discharges.
Industrial and Commercial businesses within the City can request a Stormwater Pollution Prevention Evaluation to become better informed of ways to reduce or eliminate stormwater pollution. Commercial inspection fees are listed in the Fee Schedule. The Inspection Report forms listed below will show what the inspectors will be looking for during the inspection.
For more information on either construction or industrial facilities inspections, contact our Stormwater Program Coordinator.
