Unit 3 training explains the order's definition of Controllable Sediment Discharge Sources (CSDS), the three-step requirement to assess, inventory, and treat CSDS in Category B projects, the centralized deferred-treatment inventory available to Central Valley Water Board staff, and the CSSRP requirement to cycle watershed plans every seven years and complete treatment within ten years.

Presenter described Controllable Sediment Discharge Sources (CSDS) as "an order specific term describing a location or site that presents risk to water quality" and identified three qualifying conditions: the location "causes or threatens to cause impact to water quality," is "caused or affected by anthropogenic activity," and is "under permittee control and is treatable through management measures or BMPs."
