Runway Safety Area Improvements at Allegheny County Airport (AGC)

In 2021, the Allegheny County Airport Authority (ACAA) began an Environmental Assessment of potential improvements to the Runway Safety Area (RSA) of Runway 10-28 at Allegheny County Airport (AGC).

An RSA enhances the safety of aircraft that undershoot, overrun, or otherwise leave the paved runway surface, and the airport must keep the RSA cleared, graded, drained, and accessible by firefighting and rescue equipment1. RSA standards are defined by the Federal Aviation Administration (FAA).

A standard RSA for Runway 10-28 at the Allegheny County Airport is not feasible so the analysis team, including engineering and environmental professionals, are studying the feasibility of several different solutions or combinations of solutions.

The ACAA is issuing this notice to advise the public of the availability of the Final Environmental Assessment (Final EA) and Federal Aviation Administration’s (FAA’s) Finding of No Significant Impact (FONSI) arising from implementation of runway safety area improvements for Runway 10-28 at Allegheny County Airport. The Final EA is consistent with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, and with existing national environmental policies and objectives set forth in Section 101 of the National Environmental Policy Act of 1969, 42 U.S.C. § 4321 et seq. (NEPA), Council on Environmental Quality regulations, 40 C.F.R. Parts 1500-1508, the requirements of Section 106 of the National Historic Preservation Act, and all other applicable special purpose laws. The Proposed Action will not significantly affect the quality of the human environment or otherwise include any condition requiring consultation pursuant to Section 102(2)(C) of NEPA.

The Final EA responds to agency and public comments received by the ACAA and it updates the Draft EA, which was made available for public review and comment on February 27, 2022. The FONSI documents the FAA’s decision to implement the Proposed Action alternative as detailed in and supported by the Final EA. The Final EA and FONSI/ROD are available for review for 30 days at the following locations:

  1. Online at
  2. AGC’s Airport Office at 12 Allegheny County Airport, West Mifflin, PA 15122. Please call (412) 466-3026 to schedule a date/time to review the Draft EA.
  3. ACAA will provide a hardcopy or flash drive of the Final EA and FONSI upon request. Please call (412) 476-2000 or email [email protected] to request a copy of the materials.
