In this January 1982 letter, Port of Seattle Planning Director Clifford C. Muller responds to community member Virginia Dana's concerns about the Sea-Tac Airport Noise Exposure Update Study. He addresses skepticism over the Ldn noise measurement system, defends the study's prediction that noise impact will decrease as airlines adopt quieter aircraft, and reassures Dana that shrinking noise contours do not eliminate eligibility for noise remedy programs. Muller acknowledges that the Technical Advisory Committee's input has been valuable and indicates that the upcoming Remedy Plan project will be the primary venue for addressing ongoing community concerns.Open full document
