Early November, FAA released its Record of Approval for the Ted Stevens Anchorage International Airport and Lake Hood Seaplane Base 14 CFR Part 150 Noise Compatibility Study. In the Record of Approval they note those measures that were approved and disapproved by the FAA. The full Record of Approval is included on the Documents & Links Page.
Those measures that were approved included: the continuation of the voluntary sound insulation program for those homes within the 65 DNL and greater noise contour, the voluntary use of reduced thrust (as long as it is up to the discretion of the pilot in command), the disclosure statements, building code requirements, comprehensive plan amendments, and zoning code changes (with the caveat that these are entirely under control of local jurisdictions as described in the Part 150 Study). Administrative measures approved included the development of a fly quiet program, continuation of the public information program and public comment submittal form, addressing noise comments, flight tracking, and the approval to update the NEMs and NCP as needed if there is a substantial change in noise.
Those items disapproved included: the noise barrier, the ground run-up enclosure, and gate electrification and preconditioned air at all jet bridges. The noise barrier and ground run-up enclosure were disapproved based on the fact that the benefits to non-compatible land uses would be outside the 65 DNL noise contour and therefore does not meet the Part 150 Study requirement of reducing non-compatible uses within the 65 DNL. The jet bridges were disapproved due to the fact that the FAA considered terminal based power AC as being funded through a separate funding source rather than the noise program.

Next steps including the printing of the final report and conducting a Study Input Committee meeting in early 2016 to discuss the ROA.
