Stormwater Certification (CESCL)

stormwater certification CESCL certification


Our state’s water resources including its streams, lakes, wetlands, marine waters, and groundwater provide ecosystem services in the form of recreation, drinking water, tourism, wildlife habitat, and industrial use. When rain water, also known as stormwater, carries salt, sand, soil, pesticides, fertilizers, leaves and grass clippings, oil, litter, and other pollutants into nearby waterways, it can negatively impact the ecosystem services that water body can provide. Because of these concerns, federal and state laws regulate surface and groundwater pollution from stormwater runoff. All projects that expose one acre or more in Washington State require a designated Certified Erosion and Sediment Control Lead (CESCL).

Stormwater Management

NWETC is dedicated to helping you meet and exceed environmental regulations and understand stormwater policy. We want to help you remain free of regulatory violations, which can cause projects to run over budget and over time.

Stormwater Certification

Certified Erosion and Sediment Control Lead (CESCL) certification is required in the state of Washington and Oregon by the Washington State Department of Ecology (DOE) and the Oregon Department of Environmental Quality (DEQ) for personnel responsible for construction stormwater inspections and sampling at construction sites. Our Washington stormwater certifications are valid in Oregon.  Additionally, our Oregon stormwater certifications are valid in Washington. Attendees who complete the course will receive a WA CESCL card, valid for three years.
