Subject: Notice of Availability of the Draft Environmental Assessment and Draft General Conformity Determination for the Proposed Terminal Area Plan and Air Traffic Procedures at Chicago O’Hare International Airport

The Federal Aviation Administration (FAA) has prepared a Draft Environmental Assessment and Draft General Conformity Determination to evaluate the effects of the proposed Airport Terminal Area Plan and changes to air traffic procedures at Chicago O’Hare International Airport. The FAA is seeking public comment from Federal, state, and local government agencies and officials, as well as members of the public regarding this Draft Environmental Assessment.

The Draft Environmental Assessment’s analysis will determine whether the proposed projects have the potential to significantly affect various environmental resources, such as noise, air quality, water resources, and historic facilities. 

A Public Notice regarding public workshops and public comment period for the Draft Environmental Assessment appears on or about June 2 – 8, 2022 in the Chicago Tribune, the Chicago Sun-Times, the Daily Herald, Journal and Topics, La Raza, and Reflejos.

The Draft Environmental Assessment analyzed actions proposed by the Chicago Department of Aviation, including: terminal projects, on-airport hotels, airfield and taxiway improvements not required by the terminal projects, and support facilities that are not required by the terminal projects.

The Draft Environmental Assessment also evaluated air traffic actions proposed by the FAA of making permanent the previously approved temporary offset (angled) approaches to Runway 10R/28L. The offset approaches allow for the use of simultaneous approaches to three runways and enables previously approved simultaneous approaches to four runways in the future.
