INTRODUCTION IDENTIFYING INFORMATION Title, EA Number, and Type of Project: DOI-BLM-AK-F030-2016-0009-EA; Communication Site Location of Proposed Action: The proposed tower center coordinates are 67° 15' 16.35" N, 150° 11' 05.99" W (NAD 83) near the Coldfoot Airport, mile post 175 off the Dalton Highway more particularly described as within Sec. 16, T. 28 N., R. 12 W., Fairbanks Meridian, Alaska. Name and Location of Preparing Office: Central Yukon Field Office, 1150 University Avenue, Fairbanks, Alaska 99709 Identify the case file number: F-97066 Applicant Name: GCI Communication Corporation (GCI) PURPOSE AND NEED FOR ACTION GCI is proposing to install a communication tower site on public lands near the Coldfoot Airport, mile post 175 off the Dalton Highway, Alaska. The need for action is established by the Bureau of Land Management’s (BLM) responsibility under Title V of the Federal Land Policy and Management Act (FLPMA) of October 21, 1976 (90 Stat. 2776; 43 United States Code [USC] 1761), as amended, to respond to requests for rights-of-way across public lands. The purpose of the action is to provide access across public lands in a manner that is consistent with the provisions and objectives established for the management of resources within the respective planning area and to ensure that the public uses described herein will not cause unacceptable damage to public lands. SCOPING, PUBLIC INVOLVEMENT, AND ISSUES Due to the remoteness of the area it was determined that public scoping was not necessary. This environmental assessment was posted to the BLM NEPA Register on January 26, 2016. No comments have been received as of February 24, 2016. Coldfoot Cell Tower, F-97066 Page 2 Figure 1.

PROPOSED ACTION AND ALTERNATIVES DESCRIPTION OF THE PROPOSED ACTION GCI is proposing to install a communication tower site on public lands near the Coldfoot airport, mile post 175 off the Dalton Highway within Sec. 16, T. 28 N., R. 12 W., Fairbanks Meridian, containing 2.29 acre. They propose a 20 year authorization with the option of renewal to construct, operate, maintain, and decommission. The facility would provide UMTS (3G) wireless voice and data coverage to the community because there is none currently. GCI is proposing to build an unlit, un-guyed, 80-foot-tall lattice tower on the parcel. A communications shelter (10 feet by 20 feet) would be secured on the same 25-foot-by-25-foot I-beam platform as the tower. The I-beam foundation does not require excavation and fill, but there may be a small amount of surface leveling with a bulldozer. The project would also involve construction of the following: • Wireless technology cabinets housed in the communications shelter – the cabinets would contain 850 MHz CDMA/EVEO, 850 MHz UMTS and 700 MHz LTE, DC rectifiers and battery backup plant. This shelter would not require a back-up generator. • An aerial “ice bridge” between the communication shelter and the tower – the ice bridge would provide a structure for attaching the coaxial transmission lines and offer protection from falling ice. This would not involve ground disturbance because the ice bridge would be constructed on the I-beam ballast tower foundation. • An extension of the existing chain-link fence to enclose the communications facility. • A ground ring trenched in around the base of the ballast tower foundation at a depth of 36 inches. • Buried electrical service and fiber optic cables from the existing GCI-operated fiber shelter along the ice bridge to the new site. GCI would need temporary work areas along the north, east, and south of the long-term lease area for the placement of the tower, shelter, and fencing. The dimensions of the temporary work areas would be 10 feet x 20 feet on the northwest side of lease area, 10 feet x 44 feet on the northeast side of lease area, and 10 feet x 30 feet on the southeast site of lease area (GCI 2015). GCI proposes to construct from June through July 2016. GCI would contract a construction crew of 3 to 4 workers to transport the material in two flatbed trucks on the Dalton Highway. The first truck would carry the tower sections, ballast, and I-beams and the second truck would carry the radio equipment and shelter. The ballast foundation would be filled with approximately 4,000 pounds of gravel from an existing (permitted) borrow pit to stabilize the I-beams. System turn-up and testing would occur after construction in the fall and winter of 2016. Construction workers would be housed off-site at Coldfoot Camp (GCI 2015). Coldfoot Cell Tower, F-97066 Page 4 DESCRIPTION OF ALTERNATIVES ANALYZED IN DETAIL No Action Alternative Under the No Action Alternative, BLM would not grant the lease. Currently there is no wireless voice and data coverage in Coldfoot, and that would not change under the No Action Alternative. ALTERNATIVES CONSIDERED BUT NOT ANALYZED IN DETAIL GCI considered the collocation of its wireless facilities on the Summit Telephone tower located within the community of Coldfoot, Alaska. This alternative is not feasible at this time because an agreement could not be negotiated between GCI and Summit Telephone. 3. AFFECTED ENVIRONMENT PROJECT AREA The project area is within Sec. 16, T. 28 N., R. 12 W., Fairbanks Meridian, Alaska Access/Realty The site is accessible via the Dalton Highway and then an existing road to the Coldfoot airport. The proposed site is located on land managed by BLM and is vacant, but has been disturbed by gravel fill and an adjacent underground utility line. Cultural Resources The potential site area has been previously disturbed by gravel fill and an adjacent underground utility line. No previously identified cultural resources are present within the direct area of potential effect (APE). The Coldfoot Historic District (WIS-00040) and Dalton Highway (WIS-00408) are within a half-mile visual APE. Fire Management The project location is within a Full Management Option fire management unit (Alaska Interagency Coordination Center 2015). Objectives for this management option include controlling all wildland fires at the smallest acreage reasonably possible by initial response forces without compromising firefighter safety and providing appropriate protection to identified uninhabited structures and property (BLM 2005). Coldfoot Cell Tower, F-97066 Page 5 Hazardous Waste The FCC requires eight (8) hours of back-up power be available for wireless site deployments. The typical standby power backup for wireless sites is usually accomplished by batteries. GCI Facilities Engineering has specified the use of 16 valve-regulated, non-spillable lead acid batteries (Telcordia TEL 12-210 FG). Invasive, Non-native Plant Species Invasive plants are non-native aggressive plants with the potential to cause substantial damage to native ecosystems and/or cause substantial economic losses. Over two dozen invasive plants have been recorded in numerous infestations along the Dalton Highway (BLM 2013). According to available data, 15 invasive plant species occur in Coldfoot, AK (AKEPIC 2015). The Alaska Natural Heritage Program ranks plant invasiveness on a scale from 0 to 100 (100 being the most invasive). Three of the most notable invasive species documented in Coldfoot, Alaska are oxeye daisy (Leucanthemum vulgare), white sweetclover (Melilotus albus), and bird vetch (Vicia cracca). They have invasiveness scores of 61, 80, and 73, respectively (AKEPIC 2015). All three species are considered highly invasive and are identified for eradication in the Dalton Management Area Integrated Invasive Plant Strategic Plan (BLM 2013). Recreation The proposed project site is near the Dalton Highway which is popular with tour groups and individuals for sightseeing and for accessing recreational hunting, fishing, gold panning, hiking, camping, wildlife viewing, and rafting opportunities (BLM 1989, 2014). The project site is located near the Arctic Interagency Visitor Center in Coldfoot, Alaska. Socioeconomics The tower would be located near the Dalton Highway, and currently there is no existing wireless voice and data coverage. The community of Coldfoot was founded as a mining community, but was abandoned in 1912. The current population is 10, and most residents are non-native. Fifty-nine percent of residents are employed, but there are no unemployment insurance claimants. Soils The soil at the proposed project site has been previously disturbed. Subsistence Subsistence is an important part of livelihood and culture, especially in rural Alaska. The Dalton Highway provides access to some subsistence resources such as caribou and some fish species. Subsistence resources are harvested in the Coldfoot area by residents and neighboring villages, but the proposed project site is not identified as a valuable subsistence use location. Vegetative Resources The project site has been previously disturbed by gravel fill and an adjacent underground utility line. The structure would sit above the ground on an I-beam platform. Vegetation clearing is not required for this project. Coldfoot Cell Tower, F-97066 Page 6 Visual Resources The project location is within the Koyukuk Drainages Scenic Quality Unit described in the Environmental Impact Statement for the Utility Corridor Resource Management Plan. The area is characterized by little visual variety and is not visually unique. The unit has been given a rating of Scenic Quality Class B, which is given to areas that, though pleasing to the eye, tend to be common throughout a landscape (BLM 1989). The site has been previously disturbed by gravel fill and an adjacent underground utility line. The Coldfoot Historic District (WIS-00040) and Dalton Highway (WIS-00408) are within a half- mile visual area of potential effect.
