CESCL: Certified Erosion and Sediment Control Lead Training

This course provides a 3-year Construction Stormwater Certification valid in both Washington (CESCL) and Oregon (1200C).

CESCL certification is required by the Washington State Department of Ecology Construction Stormwater General Permit for personnel responsible for monitoring stormwater at construction sites disturbing one or more acres of land.

NWETC's 2-day CESCL course is a dynamic interaction between traditional classroom lecture and hands-on field exercises. Day 1 and the first part of Day 2 cover regulations, water quality impacts, reporting requirements, and erosion/sediment control techniques. On the afternoon of Day 2, students visit a field site to practice installing erosion control BMPs.

Upon completion, attendees will have met the requirements of BMP C160 certification and will receive a CESCL card valid for three years.

Intended Audience: Contractors, agencies and municipalities, engineers, consultants, and anyone seeking CESCL certification with the Washington Department of Ecology.
