Welcome to the homepage for the Boston Logan International Airport Runway 33L RNAV SID Draft Environmental Assessment (EA). The Federal Aviation Administration (FAA) has prepared this Draft EA to identify the potential environmental effects associated with an FAA Proposed Action to implement a new air traffic control Area Navigation (RNAV) standard instrument departure (SID) procedure on Runway 33 Left (33L) at Boston-Logan International Airport.

The FAA has released the Draft EA on January 14, 2013. The Draft EA is available for review electronically from this website or in hard copy at the Framingham, Winthrop, or Boston (East Boston Branch) public libraries. In accordance with the National Environmental Policy Act (NEPA), the Draft EA was prepared to address the potential environmental impacts that could result from the implementation of a new RNAV procedure at Logan Airport. The RNAV SID procedure would be used by RNAV-capable jet aircraft and closely overlays existing flight departure corridors from Runway 33L at Logan Airport.

Public Comment Period

The comment period on the FAA's Draft EA for the Runway 33L RNAV SID at Logan Airport closes at midnight on March 15, 2013. The FAA has received numerous comments on the proposal, including many which pose questions. The FAA has attempted to respond to as many of the those questions as possible. All comments and questions, including those to which we have not responded, will be made part of the project record and taken it into consideration in FAA's preparation of the Final EA.

This Draft EA is being made available to the general public via this project website. Public comments will be accepted, summarized and considered in the FAA’s preparation of the Final EA. The FAA has extended the comment period to March 15th, 2013. Please send all written comments to:
