Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-138 Route Segment 3b would cause approximately 20.1 acres of long-term impacts on military land use on the perimeter of the JBLM YTC in Training Areas 5 and 6. Military operations in this area would be minimally affected; however, because the route segment would be on the perimeter of training activity areas and new transmission line structures would be located adjacent to an existing fire break road, impacts would be moderate because activities could continue to occur. Non-agricultural Prime Farmland would be affected by this route segment. Long-term impacts would occur to Farmland of Unique Importance, Farmland of Statewide Importance, and Prime Farmland if Irrigated totaling 7.6, 1.1 and 0.6 acre, respectively, causing moderate impacts. Potential impacts would also occur where the route segment parallels and crosses the John Wayne Pioneer Trail between MP 17.3 and 19.0, where the route segment would potentially conflict with the use of the trail. The existing ROW corridor for the trail (railroad corridor), where the route segment would be located within this corridor, is 200 feet. High impact would occur as a result of potential conversion of recreational land to non-recreational uses (new transmission line structures) (also see Section 4.5 - Recreation). Also, the proposed Wanapum NAP is crossed along this segment, causing moderate impacts. Short-term impacts would occur on Huntzinger Road and SR-243, where road users would be affected by disruption of traffic flow during construction (see Section 4.7 - Transportation). Route Segment 3b would be in compliance with the Yakima County Comprehensive Plan (2007) and all applicable development regulations, the Benton County Comprehensive Land Use Plan, and the Spokane District 1985/1987 RMP and 1992 RMP Amendment/ROD. Overall, high impacts would total 1.7 miles and moderate impacts would total 8.9 miles for this route segment. 4.4.4.10 Route Segment 3c See discussion regarding short-term construction impacts, Prime Farmlands, loss of agricultural and grazing land due to new transmission line structure footprints, potential financial impacts, impacts on aerial spraying, GPS operation, and other general short-term and long-term impacts on agricultural and grazing lands as described in Section 4.4.4.3 - Route Segment 1c. Short term impacts would occur on 60.1 acres of undeveloped/grazing lands and 33.5 acres of irrigated cropland. A portion (4.0 miles of 25.0 miles) of this route segment parallels the Hanford-Vantage No. 1 500 kV transmission line corridor with 3.4 miles being in a BLM designated utility corridor located within the Saddle Mountains Management Area (MA). A portion of the route segment that parallels the existing BLM utility corridor is located in an open road designation within the Saddle Mountains MA (1.8 miles, see Section 4.7 - Transportation). Approximately 1.6 miles located within the BLM Saddle Mountains MA and utility corridor is located in a road restricted area. Most of the BLM land in the Saddle Mountains MA is under grazing leases, and long-term impacts on these lands would total 5.7 acres. BLM oil and gas lease land would also be affected by the route segment, with 0.6 acres of long-term disturbance occurring as a result of this route segment. Rangeland and recreational use impacts would be low because the grazing would continue on these lands and off-road vehicles would be able to move under and around the new transmission line structures. Moderate impacts to land used for residential purposes would occur at MP 10.3-10.4, MP 23.6-23.7, MP 22.5-22.5, and MP 23.7-23.8. EDP Renewables has secured a wind testing and monitoring ROW in the Saddle Mountains as part of the proposed Saddle Mountains West Wind Farm in the Project study area. Route Segment 3c would cross a portion of these BLM lease lands in the Saddle Mountains MA and the entire length of the route segment in the Saddle Mountains MA would be in the wind testing and monitoring ROW. Moderate impacts could
