Storm Water Program - Trash Implementation Program

The Trash Amendments apply to all Phase I and II permittees under the NPDES municipal separate storm sewer systems (MS4) permits. The State Water Resources Control Board Executive Director sent separate 13383 Orders to traditional and non-traditional Small MS4 (see below) permittees on June 1, 2017. Regional Water Quality Control Boards, as the Permitting Authority, issued to their Phase I permittees either Water Code 13383 or 13267 Orders that contain region specific requirements, which may differ from the State Water Recourses Control Board orders.

Upon reissuance or amendment, State and Regional Water Board MS4 permits and the statewide storm water permit for the California Department of Transportation (Caltrans) will contain trash control implementation requirements and compliance milestones to demonstrate progress towards 100 percent compliance with the Trash Amendments. The General Permits for Stormwater Discharges Associated With Industrial and Construction Activities will contain the prohibition of trash in storm water and non-storm water discharges when those permits are reissued. On June 1, 2017, the State Water Resources Control Board Executive Director issued a 13383 Orders to Caltrans. 13383 Orders were not issued to dischargers of storm water associated with industrial or construction activities.
