Construction site erosion and sediment control training

WSDOT trains staff and consultants on internal policies and procedures for complying with the NPDES Construction Stormwater General Permit.

Staff can sign up for "WSDOT ENV: Construction Site Erosion and Sediment Control" in the Learning Center. Consultants can sign up for WSDOT's class if the project engineer finds it necessary. You may also take the training from an Ecology approved training provider.
