Preliminary draft 401 WQC for Third Runway

Notes

An email from Ann Kenny distributing a preliminary draft Water Quality Certification (401 WQC) for the Third Runway project at Seattle-Tacoma International Airport to the 401 team for review and feedback. The attached draft certification letter certifies that the proposed construction work complies with applicable provisions of the Clean Water Act and other state law requirements. The draft notes that stormwater-related sections require the most work and that low flow material review is still ongoing.
