Is your Certified Erosion and Sediment Control Lead certification about to expire?

The Department of Ecology requires a CESCL on all stormwater permitted construction sites over an acre and CESCL certifications must be renewed every three years with a one-day class. Designed for residential builders, BIAW's CESCL recertification class will answer builder questions, including what BMPs perform best on construction sites, how to keep those BMPs working, what red flags signal erosion problems, and how to effectively work with local and state inspectors. This class will also walk you through the planning and execution of erosion control in a subdivision.

You will receive the online class meeting info and a book link the day before the start of class. It will be sent to the email you use during registration. To receive your CESCL card and credit for the class, you must sign in for the fully scheduled class time and complete the test at the end.
