Notes
Email chain between Washington State Department of Ecology staff discussing the development of acceptable fill criteria language for the 401 Water Quality Certification related to the Seattle-Tacoma International Airport Third Runway project. The correspondence clarifies that Ecology’s fill criteria should ‘stand alone’ from US Fish and Wildlife Service requirements in its Biological Opinion, while avoiding conflicting language. Staff also discuss whether MTCA (Model Toxics Control Act) standards should be applied and questions about groundwater protection.
