Press Release

Final Environmental Assessment for Parallel Secondary Runway 11-29

June 6, 2016



Parallel Secondary Runway 11-29 At Bozeman Yellowstone

Interested parties are hereby notified that the Federal Aviation Administration (FAA) has prepared an Environmental Assessment (EA) and Finding of No Significant Impact / Record of Decision (FONSI/ROD) for the following improvements at the Bozeman Yellowstone International Airport (BZN), located southwest Montana in the Gallatin Valley and Approximately 10 miles northwest of the City of Bozeman. These actions are collectively referred to as the Proposed Action:

BZN’s Proposed Action is to construct an asphalt runway surface for the Proposed Secondary Runway 11-29 that is proposed to be 75’ wide by 5,050’ long (B-II small standards), generally parallel to the main Runway 12-30 and offset by 940’ to the northeast. It is anticipated that the proposed action will reduce congestion, improve operational efficiency, accommodate aircraft currently using and forecasted to use BZN, reduce delays, and improve safety in accordance with planning guidelines established by the FAA. The existing turf (grass) Runway 11-29 will remain in its current location (generally parallel to the main Runway 12-30 and offset by 700’ to the northeast) and the proposed Secondary Runway 11-29 will provide an alternate landing surface north of, and parallel to, the turf runway. The proposed improvements will act as one runway where either the turf or paved surface may be used as Runway 11-29, but they may not both be used for simultaneous approaches and departures. The Proposed Secondary Runway 11-29 will be VFR only and will not require any new approach procedures, or modifications to existing approaches. Other associated improvements associated with the Proposed Secondary Runway 11-29 include:

• Construction of a 35’ wide full length parallel taxiway and associated ladder taxiways for the Proposed Secondary Runway 11-29;

• Installation of supplemental wind cones;

• Installation of Medium Intensity Runway Lights (MIRL) for the Proposed Secondary Runway 11-29;

• Installation of Medium Intensity Taxiway Lighting (MITL) system including signage;

• Installation of a Precision Approach Path Indicator (PAPI) system for the Proposed Secondary Runway 11-29;

• Installation of drainage improvements to include potential surface ditches, culverts, and drainage structures (manholes and inlets).

The EA has been prepared in compliance with the National Environmental Policy Act. The purpose of the EA and FONSI/ROD is to assess the effects on the human and natural environment associated with the Proposed Action. The EA evaluated two alternatives: A) No action and B) Preferred Alternative.

The FONSI/ROD is the FAA’s finding that the Preferred Alternative will not have a significant effect on the human and natural environment associated with proposed improvements.

The FONSI/ROD and Final EA are available for a 30-day informational public review at the following locations:
