Subject: Kickoff of Boston Logan Runway 4 Left RNAV Environmental Assessment

This is a courtesy notification that the Federal Aviation Administration (FAA) awarded a contract for an Environmental Assessment (EA) for a proposed Area Navigation (RNAV) approach procedure for Runway 4 Left (L) at Boston Logan International Airport (BOS).

FAA conducted an Initial Environmental Review with technical analysis support from the Volpe Transportation Center in 2015, which included a noise analysis. We coordinated with the Massachusetts Port Authority (Massport), the Logan Community Advisory Committee (Logan CAC), and Congress on the BOS 4L proposal, and conducted a public meeting in 2015. The noise analysis for the permanent use of the procedure did not result in a reportable or significant noise impact over residential areas. However, the FAA agreed to conduct an EA. The EA project entered the budget planning and prioritization process and was recently funded.

[FAA] anticipates providing an overview of the project to the Massport Community Advisory Committee (MCAC) at their next quarterly meeting in January, 2020. This discussion will be in advance of the formal community engagement process which will include notifying the general public, community workshops, and the opportunity for the public to comment on the Draft EA, when it is completed later in 2020.

The FAA will work closely with Massport and the MCAC to ensure a timely flow of information.

Note: Sent to stakeholders (local, state, and federal) in the following communities: South Boston, Roxbury, Milton, Dorchester, Mattapan, Quincy, Hyde Park, Braintree, Canton, Randolph, and Blue Hills Reservation.
