Interim Fly Quiet Report

Amy Hansen, environmental specialist for the FAA, reported that the agency received the City of Chicago’s submittal for contract approval of the third-party consultant for the Interim Fly Quiet (IFQ) environmental impact study. The FAA works with airport sponsors who take direction from the FAA. She estimates that once the scope of services has been approved and the contract signed, the process will take approximately one year to complete. The FAA will submit a draft report of the study, hold several public workshops to address resident comments and then present a final environmental report. Once approved, the IFQ will be in effect until the commissioning of Runway 9C/27C in fall 2020.
