    The Sound Insulation Treatment Repair and Replacement Program Act

    A legislative proposal by Rep. Adam Smith (WA-09) that would allow the FAA to waive regulations preventing airports from using federal AIP funds to repair or replace defective sound insulation in homes.

    Airport Noise Remedy Update Work Program: Phase and Task Descriptions

    The objectives of this study are to evaluate and update the schedule and scope of the aircraft noise remedy program contained in the 1970 Sea-Tac/Communities Plan. The study will address the updated noise projections presented in the 1982 Sea-Tac Noise Exposure Update Study, the extent of the progress made toward implementing the original noise remedy program, and the most recent assessment of present and future finances and local attitudes and interests. The updated noise remedy program will provide the Port of Seattle with recom- mendations of new or revised noise re~edy/abatement measures. The study will follow the standards for developing an airport noise compatibility planning program under FAR Part 150. The work program for the study consists of Design Elements, Project Eleme11.ts, Miscellaneous Elements, and Administrative Elements. The sequence of tasks in each of these four elements and a project schedule are presented in Exhibit 1, and the project organization is shown in Exhibit 2. Design Element tasks include a study design, coordination with governmental agencies as necessary to obtain federal funds for the study, and the develop- ment of an extensive Community Involvement Program. Project Element tasks include the identification and evaluation of appropriate noise abatement/remedy measures and the development of an updated noise remedy program. -1- 0868p - 02/04/83 l1iscellaneous Element tasks include the review of certain land use density guidelines as well as of Airport land use development guidelines.
