Certified Erosion and Sediment Control Lead Recertification

Every site disturbing one or more acres of land or part of a larger common plan of development MUST have a CESCL on site to monitor stormwater using Best Management Practices (BMPs). This one-day online CESCL recertification class is recognized by the Washington State Department of Ecology (Ecology).

This course will cover:

  • Regulations
  • Impacts to water quality
  • Reporting and record keeping requirements of the permit
  • Up to date erosion and sediment control techniques
  • Best Management Practices (BMPs)

CESCL certifications are valid for three years. You have a six month grace period after the expiration of your CESCL; beyond that, you must take the initial training again.
