Update - January 2022:
The FAA has updated this website to include the project correspondence related to the impact of the Proposed Project, also known as the undertaking, on historic resources within the project’s study area. The FAA has proposed a Finding of No Adverse Effect to historic resources for the undertaking and this correspondence is part of the consultation process under Section 106 of the National Historic Preservation Act. Links to the correspondence can be found under the Project Information tab above. As comments on the Draft Environmental Assessment are still being considered and the FAA continues to engage in the Section 106 consultation process for historic resources, no final decision has been made on the environmental review of the BOS RNAV (GPS) Runway 4-Left Approach procedure. The Final Environmental Assessment is expected to be published in mid to late 2022.
