This checklist is a starting point. Check each item against your current permit and your agency's standards before relying on it. Based on the Ecology Construction Stormwater General Permit and the Stormwater Management Manuals for Western and Eastern Washington. Sites of 1 acre or more sample turbidity and, with significant concrete work, pH. Check each template against the current permit and your local requirements before relying on it.
