Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-137 High impacts would occur for 2.9 miles and moderate impacts would occur for 12.7 miles of this route segment. 4.4.4.7 Route Segment 2d Long-term land use impacts occurring as a result of the construction or Route Segment 2d will primarily be to BLM grazing lease lands. A total of 1.4 acres of long-term impacts and 2.6 acres of short-term impacts will occur for this route segment. Prime Farmland impacts will also occur in non-agricultural areas. Long-term impacts will occur on 4.5 acres of Farmland of Unique Importance and 8.2 acres of short-term impacts will occur. CRP lands would also be affected by this route segment. In crossing PLSS sections known to have CRP designated lands, long-term impacts totaling 0.3 acre could potentially occur. However, the location of these lands within the section crossed is unknown. CRP lands crossed by the route segment would need an FSA assessment of the adverse effects on the participants CRP acreage. See other CRP land impact discussion in Section 4.4.4.5 - Route Segment 2b. As stated in Section 3.4, the exact parcels of CRP lands are not known. Pacific Power would consult with the FSA and landowners to determine if the construction of the route segment would affect the CRP status of the land or if special construction or revegetation would be necessary. Pacific Power would provide landowners with information, including estimated land disturbance to ground cover and length of use, if required to obtain prior approval from the FSA for ground disturbance prior to ground disturbance on CRP lands. The route segment would be consistent with the Yakima County Comprehensive Plan (2007), Benton County Comprehensive Plan (2006), and the Spokane District 1985/1987 RMP and 1992 RMP Amendment/ROD. The route segment would be subject to YCC 19.18.260(4) – Linear Transmission Facilities, and would require a Type II review. Moderate impacts would occur for 4.3 miles and low impacts would occur for 2.4 miles of this route segment. 4.4.4.8 Route Segment 3a This route segment is located adjacent to the Vantage Substation along the existing utility corridors. Land use impacts would be moderate for this route segment due to the route segment crossing the proposed Wanapum Natural Area Preserve (NAP). 4.4.4.9 Route Segment 3b See discussion regarding short-term construction impacts, Prime Farmlands, loss of agricultural and grazing land due to structure footprints, potential financial impact, 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 total 49.0 acres on military lands for this segment. No direct or high impacts are anticipated in this route segment. During route segment ROW corridor acquisition and detailed design (by Pacific Power), the assumed centerline of this route segment would be adjusted to avoid the need for removal of dwellings or related structures. Therefore, with prudent adjustments to the location of the route segment’s ROW corridor and transmission line structure placement no direct impacts to existing dwellings or related structures are foreseen. Moderate impacts would result from long-term elimination or limitation of any structure placement or development under the new transmission line within the route segment ROW corridor.
