Welcome to the website for the Environmental Assessment of the RNAV (GPS)
Runway 4-Left approach procedure at Boston Logan International Airport.

This site was created to provide an overview of this environmental document prepared by the FAA for the new approach procedure. It will help you better understand the environmental process under the National Environmental Policy Act (NEPA), understand the potential impacts of this proposed procedure, and allow the public to comment on the Draft Environmental Assessment.

Noise Impacts

An interactive map was created as part of the Environmental Assessment to allow the community to review the calculated noise impacts at population centroids, public parks/recreation areas, and historic resources in the General Study Area.

Comments

The FAA is accepting comments on the Draft EA. Comments will become a part of the public record. The FAA will review and consider all comments it receives as it develops the final Environmental Assessment.

Virtual Workshops

In accordance with social distancing guidelines published by the Centers for Disease Control and Prevention (CDC), the FAA has scheduled two public workshops where individuals can learn more about the FAA’s Draft EA, ask questions and make comments about the Draft EA.
