Washington CESCL Program

CESCL Certification Program Overview

This Ecology approved Certified Erosion and Sediment Control Lead (CESCL) certification is required to perform stormwater monitoring and inspections on construction sites.  

This CESCL-"Hybrid" certification incorporates two learning modalities: Online/On-demand courses, and Live Virtual Instruction.

This program consists of:

  • Six (6) Online/On-demand interactive courses that include embedded Field Videos, and
  • One (1) 6-hour Virtual Instructor-Led Training (VILT) class.

The VILT day is broken into three (3) sessions.  This video conference format allows you to communicate with your instructor and collaborate with fellow learners.

  • Thursday, July 18th at 9:00am PST
  • Thursday, August 15th at 9:00am PST

Trainer: Alex Zimmerman

CESCL certifications are valid for three (3) years.

Note: 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. (Local jurisdictions may require CESCL certification for sites less than 1 acre, neither does the CSWGP, except in limited cases.)
