Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-136 grazing lands as described in Section 4.4.4.3 - Route Segment 1c. Short-term impacts would occur on 13.1 acres of irrigated cropland for this route segment. A portion (8.6 miles of 18.1 miles) of this route segment parallels an existing utility ROW corridor located on private lands. A portion of the route segment that parallels the exiting utility corridor would also be located in irrigated agricultural land and, potentially, CRP lands. Approximately 2.5 acres of long- term disturbance would occur in irrigated agricultural land and 3.5 acres of long-term disturbance would occur in CRP Land. Long-term disturbance would occur to cropland under cultivation as wheat, Timothy, apple, alfalfa hay and wildlife feed. Most of this agricultural land (80 percent) is Farmland of Statewide Importance, Farmland of Unique Importance, and/or Prime Farmland if Irrigated and these lands would be converted to non-agricultural uses. Other non-agricultural land is designated as Prime and Unique Farmland or Farmland of Statewide importance, also. Conversion of Prime Farmlands to non-agricultural uses would require a Farmland Conversion Impact Rating from the U.S. Department of Agriculture. Long-term impacts totaling 2.5 acres on Farmland of Statewide importance, 6.5 acres on Unique Farmland, and 0.8 acres on Prime Farmland would occur. The operation of five center pivot irrigation systems would be impacted as a result of the presence of this route segment. The route segment would cause long-term impacts on 1.0 acre of center pivot agricultural areas and less than 0.1 acre of sprinkler irrigated land. Conflicts with agricultural operations associated with the new transmission line structures located at MP 11.0 will cause high impacts. CRP lands would also be affected by this route segment. Long-term impacts totaling 0.4 acre would occur to known CRP lands. In PLSS sections crossed known to have CRP designated lands, long-term impacts totaling 3.5 acres could potentially occur. However, the location of these lands within the section crossed is unknown. CRP lands will be crossed by the new transmission line would need an FSA assessment of the adverse effects on the participants CRP acreage. If the FSA determines that the use will have an adverse effect on CRP acreage, the affected acreage will be terminated and refunds assessed. 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. Annual lease payments to CRP enrollees are not likely to be reduced, despite the potential for long-term disturbance and reduction of CRP acres due to the presence of structure footprints and access roads and, therefore, moderate impacts are assumed. Washington State Department of Natural Resources (DNR) state trust land grazing lease lands would also be affected by the construction of this route segment. Long-term impacts would occur on 0.7 acre of state trust grazing lease lands. Long-term impacts totaling 1.4 acres of BLM grazing lease allotments would also occur along this route segment. Non-irrigated fallow wheat agricultural land would also be affected by this route segment between MP 9.5 and 9.6 and wildlife feed crops between MP 13.1 and 13.7. Long-term dryland impacts total 4.2 acres and short-term impacts total 0.8 acres for this route segment. The route segment would cross private land in Yakima County, and would be consistent with the Yakima County Comprehensive Plan (2007). The route segment would be subject to YCC 19.18.260(4) – Linear Transmission Facilities, and would require a Type II review.
