What is an Illicit Discharge?

llicit discharges are generally any discharge into a storm drain system this is not composed entirely of stormwater. The exceptions include water from fire fighting activities and discharges from facilities already under an NPDES permit. Illicit discharges are a problem because, unlike wastewater which flows to a wastewater treatment plant, stormwater generally flows to waterways without any additional treatment. Illicit discharges often include pathogens, nutrients, surfactants, and various toxic pollutants.

If you see water running down the street and there are no firefighting or water operations activities going on in the immediate area, please report it to the LOCSD main office at 805-528-9370.

You may also report illegal dumping by clicking on the link at the bottom right and fill in the form.  This goes directly to the San Luis Obispo County Environmental Health Department. 

More on Stormwater from the USEPA

The Los Osos Community Services District is a member of the Central Coast Partners for Water Quality. The Central Coast Partners for Water Quality (or Partners) is a group of communities that convene to discuss, develop, and implement region-wide approaches for municipal stormwater programs for the protection of our rivers, creeks, bays, and ocean.

The goal of the Partners is to implement municipal stormwater programs consistent with state regulations.  The Partners provide an opportunity for intergovernmental coordination when implementing consistent public education campaigns and other municipal stormwater program components.
