you need a Construction Stormwater General Permit from Ecology? If your
project disturbs over an acre of land or is in a subdivision, you
probably do. This permit states that all sites disturbing over an acre
of land must have a Certified Erosion and Sediment Control Lead (CESCL).
The CESCL is trained to inspect, install, and manage stormwater
controls on your site. Ecology requires a CESCL to be on-call at all
times, so most companies will need more than one employee trained as a
CESCL. This certification is good for three years.
