F-35 Operational Beddown – Pacific – Supplemental Environmental Impact Statement

F-35 Operational Beddown in the Pacific, Supplemental Environmental Impact Statement

Cardno conducted an expedited NEPA project and provided subject matter experts to evaluate several resources that include air quality (criteria pollutants and greenhouse gases), cultural resources, natural resources, water resources, and hazardous materials/waste.

The Air Force contracted Cardno to undertake a Supplemental Environmental Impact Statement (SEIS) to address changes made since the completion of the F-35A Operational Beddown – Pacific EIS (original EIS) and signature of the Record of Decision (ROD) in April 2016, announcing the Air Force decision to beddown two squadrons of F-35A aircraft at Eielson Air Force Base (AFB), Alaska.

The original EIS evaluated infrastructure construction, demolition, renovations, additional personnel, and increases in aircraft operations at the airfield and in the Joint Pacific Alaska Range Complex (JPARC) airspace. After the ROD was signed, several new infrastructure projects were identified. The Air Force proposed to provide additional stormwater runoff control; develop equipment and material laydown areas; and provide additional heat, water, and power to the South Loop. Cardno completed the SEIS, from Description of the Proposed Action and Alternatives approval to ROD signature, in less than a year.

For Section 7 Consultation, Cardno evaluated the potential for impacting historic properties from the three proposals, and assisted the Air Force in consulting with the State Historic Preservation Office. Cardno also assisted Eielson AFB in conducting government-to-government consultation with 12 Native Alaskan villages.

Approximately 27 acres of wetlands would be removed by implementing the proposed actions. Cardno conducted wetlands delineations and submitted a report on our findings. The base used this information for completing Section 404 consultation with the U.S. Army Corps of Engineers. The entirety of the proposed actions would occur within the 100-year floodplain. Cardno notified the public, addressed this issue within the SEIS, and concluded that there were no other practicable alternatives for placing the proposed actions in the floodplain.

Cardno conducted public involvement associated with these proposals that consisted of maintenance of a public website (including a commenting forum), public notifications in local newspapers and press releases, scoping, interagency and intergovernmental coordination, and completion of a public hearing meeting. We created and produced the poster displays and handout materials for the hearing and provided risk communication training for Air Force personnel prior to meeting the public.
