We are happy to now offer CESCL certification courses at a new reduced price.

CESCL certification is required in the state of Washington by the Washington State Department of Ecology for personnel responsible for construction stormwater inspections and sampling at construction sites. Students who complete the course will receive a Certified Erosion and Sediment Control Lead (CESCL) card, good for three years.

NWETC’s 2-day CESCL course is a dynamic interaction between the traditional classroom style and hands-on exercises.

Day 1, and the first part of day 2 is spent in the classroom, examining the most up-to-date techniques in the management of sediment and construction sites and discussing regulations, impacts, case studies, and more. 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 and practice choosing and correctly installing mats, blankets, check dams, bonded fiber matrix, straw, and other erosion control techniques for various site locations. Demonstrations will also be conducted to show how the correctly placed BMP’s respond to water flow.

Upon completion attendees will know how to simply and confidently comply with federal, state, and local regulatory requirements of stormwater management.

"[Instructor Nathan Hardebeck is] well versed and experienced-can bring a lot of on-the-ground perspective.  Understands environmental values and is non judgmental about regulations." I. Sinks, March 2013

"[Nathan is ] great, engaging and knowledgeable on current laws." R. Long, March 2013

"Instructors (Nathan Hardebeck and Nate Holloway) did a great job keeping information interesting and giving real life explanations." B. Daniels, March 2013



NOTE: This  CESCL certification course is recognized as meeting the training and certification requirements of the General Permit, and BMP C160 Certified Erosion and Sediment Control Lead (CESCL) in Washington State Department of Ecology’s stormwater management manuals. The Construction Stormwater General Permit requires that site inspections be conducted by personnel certified in CESCL.


Intended Audience:

Contractors, agencies and municipalities, engineers, consultants and anyone else who desires to receive their CECSL certification with the Washington Department of Ecology.



Continuing Education Units: 1.60 CEUs
