RE: Re-Evaluation of DART Orange Line DFW Airport Extension Irving-3 Environmental
Assessment
Dear Ms. Hayes:
The Dallas/Fort Worth International Airport (DFW) and the Dallas Area Rapid Transit (DART)
have submitted a Re-Evaluation of DART Orange Line DFW Airport Extension Irving-3
Environmental Assessment to the Federal Aviation Administration for review. This document,
dated April, 2012, addresses the environmental impacts of proposed revisions to the Project since
the issuance of the Finding of No Significant Impact on October 11, 2011.
FAA Order 1050.1E, Environmental Impacts: Policies and Procedures. provides for the
preparation of a written reevaluation if the:
(1) Proposed action conforms to plans or projects for which a prior FONSI has been
issued:
(2) Data and analyses contained in the previous EA and FONSI are still substantially
valid; and
(3) Pertinent conditions and requirements (all) of the prior approval have, or will be, met
in the current action.
This written reevaluation provides the responsible FAA official the information necessary to
determine whether the consideration of alternatives, impacts, existing environment, and
mitigation measures as set forth in the original EA remain applicable, accurate, and valid.
I have reviewed the DFW/DART document and conclude the contents of the previously prepared
Environmental Assessment and FONSI remain valid, and no further action is necessary. The
preparation of a new FONSI is not required.
