A number of NPDES permit program areas affect how a municipality handles its sanitary wastewater and stormwater runoff. Municipalities rely on assistance from other partners, such as industry, developers, and homeowners, to ensure that they can meet the requirements contained in their municipal NPDES permits. Municipal staff, who are responsible for meeting NPDES permit obligations, must understand how the NPDES permit program works, who should be involved and educated about the NPDES program, and what information is available to help perform their jobs effectively.

DAS Storm drain markers are part of the public education and awareness portion of National Pollutant Discharge Elimination System (NPDES).  These markers are installed on streets with high pedestrian volume and near resource areas.  The markers indicate that the storm drain or catch basin drains directly to the ocean.  The importance of this is that storm water only should flow through this system. The system is not a receptacle for motor oil, animal feces, leaves, trash, or other such items because this outlet flows directly to the ocean. We want our ocean and beaches to be as clean and usable as possible.
