YELLOWSTONE NATIONAL PARK, Wyo. — If approved, Yellowstone National Park (YNP) will begin the installation of 187 miles of fiber optic cable in previously disturbed areas along park roads in spring 2023.

The National Park Service (NPS) signed a Finding of No Significant Impact (FONSI) for an environmental assessment (EA) to improve telecommunications systems in the developed areas of Yellowstone National Park. The FONSI was approved in 2021. Although the environmental review process was completed last year, the park continued to evaluate other impacts and needs of this significant project prior to implementation.

Work by the applicant, Diamond Communications LLC, is not authorized to begin until a right-of-way (ROW) permit is approved and issued. The park is evaluating the issuance of a ROW permit this year, and if approved, work would begin in the spring of 2023.

Yellowstone prepared an Environmental Assessment to evaluate potential impacts and determine if the park should authorize a right-of-way (ROW) permit from Diamond Communications, LLC. to install a fiber optic cable along 187 miles of park roads.

The park’s existing microwave radio system was originally installed between 1979-1990. Telecommunications and data services carried on the system are highly unreliable and do not adequately support the park’s needs for emergency communications, operations, and other forms of communications. The telecommunications services provider repaired the current system a total of 66 times in 2021.

Installation of fiber along the road corridor will enable the park to remove 25 (five reflector panels and 20 antennas) pieces of antiquated and obsolete telecommunications equipment currently located on numerous mountain tops and backcountry sites, while substantially improving the connection speeds needed for management and operations of the park.

The park encouraged public comment on this project in October 2020 and March 2021 and received in total 288 pieces of correspondence. All substantive comments received during the comment periods were considered during the decision process. Park responses to comments can be found on Page 12 of the FONSI.

Additional project details include:

  • Telecommunication systems can be considered a utility and, like other utilities, are authorized on NPS lands using the ROW permit process.
  • About 8% of the park is currently covered by cellular service which is intended to provide service only in developed areas and not along roadways or in the backcountry.
  • There is no plan to expand authorized cellular coverage beyond existing coverage areas.
  • Fiber will allow for a better quality of service within existing coverage areas.
  • This project is consistent with Yellowstone National Park’s Wireless Communications Services Plan that was completed through an EA in 2009.
  • Plans are proceeding to relocate cell towers from ridgetops to less visible sites in developed areas at Old Faithful and Mammoth Hot Springs.
  • No new cellular towers will be installed under this project.
  • The applicant will pay for all up-front construction costs.
  • Most of the fiber optic cable will be buried in a 1-¼” conduit along park roadways.

For NPS staff, partners and visitors include this will improve telephone, cellular phone, park computer networks and broadband internet services to meet critical park operations, safety and emergency services and visitor information needs and expectations in developed areas.
