CESCL certification is required by the Washington State Department of Ecology, Construction Stormwater General Permit for personnel responsible for monitoring stormwater at construction sites disturbing one or more acres of land, or are part of a larger common plan of development. NWETC’s 2-day CESCL course is a dynamic interaction between traditional classroom style lecture and hands-on field exercises. Interactive dialogue between the attendees and the trainers is also promoted, to encourage a shared learning environment.

Day 1, and the first part of day 2 is spent in the classroom, discussing regulations, discussing impacts to water quality and construction activity, learning the reporting and recordkeeping requirements of the permit, and examining the most up-to-date erosion and sediment control techniques using examples and case studies. Best Management Practices (BMP) products are brought into the class to allow students to see first hand the types of control measures there are available to them in the industry. At the end of the morning on Day 2, the required CESCL exam will be given. 

On the afternoon of day 2, the class will visit a field site to learn more about the BMP products and practice correctly installing a variety of erosion control BMPs. Other BMP demonstrations will also be conducted and the BMP installations performed by the students will be tested against a mock rain event.

Upon completion attendees will have met the requirements of BMP C160 certification and will receive a CESCL card valid for three years.
