In a June 22, 2021 letter, Seattle-Tacoma International Airport (operated by the Port of Seattle) raised formal concerns about a Public Health–Seattle & King County report examining community health impacts from airport-related noise and air pollution. The Port objected that it was not consulted during the report's development and questioned the methodology, noting that SEA aircraft account for only about 0.25% of total PM2.5 emissions in the region.
