The Regional Commission on Airport Affairs (RCAA) submitted formal scoping comments on the proposed Sea-Tac Airport Master Plan Update, which includes the addition of a third runway, calling for the Environmental Impact Statement to comply fully with both federal NEPA and state SEPA requirements. The RCAA emphasized that the EIS must be a comprehensive, nonpartisan document that is accessible to ordinary citizens and public officials, complete with proper citations, consistent terminology, indexed appendices, and clearly sourced maps and data. The comments also urged that all environmental impacts be analyzed across multiple time horizons, including the full useful life of the proposed runway, and that all study documents be made freely available to the public throughout King and Pierce Counties.Open full document
