A‍s we reported at the March 1 ONCC General Meeting, the Chicago Department of Aviation (CDA) and the Federal Aviation Administration (FAA) have signed a Memorandum of Understanding (MOU) "to establish an understanding between the Parties regarding the responsibilities of the Parties and the conditions and procedures to be followed in the development and preparation of the FQ21 environmental review."

The MOU "provides a framework and describes the relationships under which the United States Department of Transportation through the Federal Aviation Administration (FAA) will evaluate the City of Chicago's Department of Aviation (CDA) proposed Fly Quiet 21 Plan (FQ21) at Chicago O'Hare International Airport (ORD)."

One of the first steps in the process is to conduct environmental modeling of the proposed FQ21 using FAA-approved models under the oversight of FAA.

FAA-accepted environmental modeling results will be used to determine the level of environmental review required for the FQ21 proposal.

ONCC is working with both the CDA and FAA to learn more about the next steps and will continue to update members as more information becomes available.
