The FAA completed a Written Re-Evaluation of the O'Hare Modernization Environmental Impact Statement for the Proposed Interim Fly Quiet Runway Rotation Plan.

Since September 2015, the Fly Quiet Committee of the O'Hare Noise Compatibility Commission (ONCC) worked with the Chicago Department of Aviation (CDA), airlines, and the FAA to evaluate ways to improve the existing Fly Quiet Program to reduce noise concerns.

The ONCC oversaw three Fly Quiet Runway Rotation Plan tests to collect data on proposed runway configurations that could provide near-term relief to the highest impacted communities surrounding O'Hare. The results of all three tests can be found on the CDA's Fly Quiet page. In December 2017, the ONCC recommended that the Test 3 be submitted to the FAA for a Proposed Interim Fly Quiet Runway Rotation Plan. The CDA submitted the request to the FAA in February 2018.

In the Re-Evaluation, FAA examined the potential effects of Proposed Interim Fly Quiet on key environmental aspects, including noise, air quality, and environmental justice. It is important to note that the Proposed Interim Fly Quiet would be implemented in November 2019 through January 2021, when Runway 9R/27L is closed for extension construction. Runway construction, maintenance, and/or pavement rehabilitation impacts the Proposed Interim Fly Quiet during the 2019 and 2020 construction seasons. Interim Fly Quiet would not occur during construction periods.
