The Des Moines City Council submitted a series of formal questions challenging the Port of Seattle's environmental review of its airport expansion plan, raising concerns about air quality, noise impacts, and community compensation. Key issues include the Port's heavy investment in Sustainable Aviation Fuel despite its limited near-term viability, the use of outdated federal noise standards, failed home noise-mitigation packages with no funding to repair them, and whether the SEPA review adequately analyzed hazardous air pollutants and peak traffic impacts. The Council also questioned whether the Port should provide direct financial assistance to affected neighboring cities, citing a state solicitor general opinion that such payments may be legally permissible.Open full document
