Legal analysis examining how federal aviation law’s emphasis on procedure and preemption fails to adequately address community concerns about aircraft noise impacts. Discusses the limitations of DNL metrics, FAA’s Neighborhood Environmental Survey findings, and recent changes to environmental justice requirements.

have received your letter of January 7 expressing concerns regarding the Noise Exposure Update , After some staff review of the points made in your letter , I was able to chbt on the telephone with several of you to get addi-- tiona1 perspectives + On the whole, the comittee meetings , your letter , and other conversatioIls reinforce the seriousness and importance of the Noise Forecast Updatq Study and the upcoming Remedy Plan project e There seems to be agreement , disagreement , and concerns e Many of your concerns center on the Studyts use of the Ldn system in the corresponding Integrated Noise Model (INM) , We realize that many people in the affected community would like to take a more fundamental approach based on their own perceptions and attitudes regarding aircraft noise 8 We continue to believe, however, that inasmuch as this noise description is widely accepted as a national norm by the FAA, EPA and others that it must be used © Regarding your skepticism over the Studyt s prediction that noise impact will decrease in the future, we are optimistic that the replacement and/or retrofit of aircraft needed to unfluence noise impact will in fact occure We realize that airlines are facing significant economic problems e But we remain encouraged by the fact that fuel saving measures (new engines , new aircraft) should be taken into account © Your concern that 'las noise contours shrink so does the possibility that remedies will be made available11…
