2015 Re-Evaluation of the O'Hare Modernization Environmental Impact Statement

The City of Chicago (City) has undertaken a program to modernize Chicago O'Hare International Airport (O'Hare) as approved in the O'Hare Modernization Environmental Impact Statement issued by FAA in July 2005. Designed to facilitate a primarily east and west traffic flow, the O'Hare Modernization Program (OMP) Build-Out is depicted on the FAA-approved Airport Layout Plan for O'Hare. The OMP runway projects completed include: new Runway 9L/27R on the north airfield and the extension to Runway 10L/28R on the south airfield, both of which were commissioned in 2008; and new Runway 10C/28C that was commissioned on October 17, 2013.

In January 2011, both United and American Airlines filed a state court lawsuit against the City regarding the timing and funding for the Completion Phase of the OMP. In March 2011, following negotiations with signatory airlines, it was announced there would be a construction schedule modification to the remaining airfield projects included in the OMP. The negotiations led to an agreement on a schedule to construct portions of the Completion Phase (Phase 2A) and an agreement to reconvene in March 2013 to begin to negotiate construction of the remaining portions of the Program (Phase 2B). Phase 2A includes the southern Runway 10R/28L and associated projects, plus North Airfield enabling projects (see diagram). Specifically, the commissioning of new Runway 10R/28L, new Runway 9C/27C and the extension of Runway 9R/27L would not occur within a single year, 2013, as previously documented in the EIS. Instead, Runway 10R/28L will be commissioned on October 15, 2015, new Runway 9C/27C is planned to be commissioned in November 2020, and the extension of Runway 9R/27L is planned to be commissioned in November 2021.

Substantial steps have been taken, and continue to occur, to construct Runway 9C/27C and the extension to Runway 9R/27L, including site preparation and construction of enabling projects. The current Re-Evaluation of the O'Hare Modernization Environmental Impact Statement will enable the FAA to consider and disclose any temporary impacts associated with the modified construction schedule. As noted above, the final airfield project – the extension of Runway 9R/27L just north of the terminal complex – is planned to be commissioned by November 2021, and when open, will represent the full completion of the Build Out presented in the original Environmental Impact Statement.

This Re-Evaluation was conducted to evaluate changes associated with the airfield construction schedule modifications that alter the timing for commissioning new Runway 10R/28L, new Runway 9C/27C, and the extension of 9R/27L, all of which were included in the original EIS but at different completion dates than those above. As such, the two interim conditions evaluated in this Re-Evaluation are:

  • Airfield present after the October 15, 2015 commissioning of Runway 10R/28L, and
  • Airfield present after the November 2020 commissioning of Runway 9C/27C.

A Re-Evaluation is a document the responsible FAA official prepares to document the validity of an Environmental Assessment or an Environmental Impact Statement. Conversely, a Re-Evaluation may conclude that substantial changes to the project or new information pertaining to affected environmental resources require preparation of a new Environmental Assessment or Environmental Impact Statement (FAA Order 5050.4b Para. 5(v)). This Re-Evaluation of the Environmental Impact Statement was being prepared to determine the validity of the Environmental Impact Statement by demonstrating if the data and analyses of the original Environmental Impact Statement are still substantially valid and if there are no new circumstances bearing on the original Proposed Action or its impacts. It also was conducted to determine if pertinent conditions of the prior Environmental Impact Statement approval have been shown to have been met or that they still will be.

Public Workshops

The FAA sought comments from Federal, State, local entities, and the public on the Draft Re-Evaluation. The FAA conducted four public workshops on:

The meetings were workshop style with a room for the public to ask questions to the FAA and its consultants directly, with presentation boards depicting information contained in the Draft Re-Evaluation. There also were separate rooms with multiple court reporter stations for the public to provide verbal comments, on the record, after participating in the workshop. Comment forms were also available for use at the workshops.

Commenting on the Draft Re-Evaluation of the O'Hare Modernization EIS

The comment period on the Draft Re-Evaluation was from July 27, 2015 through August 26, 2015. Comments were directed to Ms. Amy Hanson, Federal Aviation Administration, 2300 East Devon Avenue, Des Plaines, Illinois 60018; (847) 294-7046 (facsimile); or via email: Comments must have been postmarked and emails sent by no later than by midnight on August 26, 2015.
