Washington CESCL Program

CESCL Certification Program Overview

This Ecology Approved Hybrid CESCL Certification is required to perform stormwater monitoring and inspection on construction sites.  

This Certified Erosion and Sediment Control Lead (CESCL) credentialing program is comprised of six (6) Online and four (4) Live virtual instructor-led courses.  

As mandated by the Department of Ecology, CESCL certifications are valid for three (3) years.   

All construction projects within the State of Washington must designate at least one (1) person as the responsible representative in charge of Erosion and Sediment Control (ESC), and water quality protection. For projects larger than one (1) acre, the designated person shall be the CESCL who is responsible for ensuring compliance with all local, state, and federal erosion and sediment control and water quality requirements. (Note: Local jurisdictions may require CESCL certification for sites less than 1 acre, neither does the CSWGP, except in limited cases.)
