Vantage to Pomona Heights Chapter 4 230 kV Transmission Line Project FEIS Environmental Consequences PAGE 4-143 This route segment also crosses land classified as Farmland of Statewide Importance (0.3 mile) causing 0.3 mile of long-term disturbance. However, this is non-agricultural land, so impacts would be moderate. The route segment would be in compliance with the Final Cultural and Natural Resources Management Plan for the JBLM YTC. Overall, moderate impacts would occur for 6.4 miles of this route segment. Underground Design Option Route Segment NNR-6u would cross approximately 6.4 miles of the JBLM YTC resulting in long-term impacts. Training Area 1 would be crossed between MP 0.0-2.2. Training Area 3 would also be crossed between MP 2.2-6.4. Military operations in this area would be minimally affected because the underground alignment would be located adjacent and parallel to Pacific Power’s existing Pomona- Wanapum 230 kV transmission line. Impacts would be moderate because the area available for training activities would be reduced, although activities could continue to occur. This route segment also crosses land classified as Farmland of Statewide Importance (0.3 mile) causing 0.3 mile of long-term disturbance. However, this is non-agricultural land, so impacts would be moderate. The route segment would be in compliance with the Final Cultural and Natural Resources Management Plan for the JBLM YTC. Overall, moderate impacts would occur for 6.4 miles of this route segment. 4.4.4.16 Route Segment NNR-7 Route Segment NNR-7 would cross approximately 8.2 miles of the JBLM YTC resulting in long-term impacts. Training Area 3 would be crossed between MP 0.0-8.2. Military operations in this area would be minimally affected 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 the area available for training activities would be reduced, although activities could continue to occur. This route segment also crosses land classified as Farmland of Statewide Importance (1.6 miles), causing 0.3 mile of long-term disturbance. However, this is non-agricultural land, so impacts would be moderate. The route segment would be in compliance with the Final Cultural and Natural Resources Management Plan for the JBLM YTC. Overall, moderate impacts would occur for 8.2 miles of this route segment. 4.4.4.17 Route Segment NNR-8 Jurisdictions crossed by this route segment are private lands in Grant County, BLM, Grant County Public Utility District, and Reclamation. Route Segment NNR-8 is located in Kittitas County and Grant County (south of Wanapum Dam on the east side of the Columbia River). The route segment parallels the existing Bonneville Power Administration-PacifiCorp utility corridor across the Columbia River south of the Wanapum Dam. The new transmission line Columbia River crossing structures could potentially affect aviation activities by modifying aircraft operations and air navigation. There are two RCO funded projects within the Project study area of this route segment: Wanapum State Park Boat Launch Replacement Grant #00-1519 and Wanapum NAP Grant #08-1185, #10-1474, and #12-1182. These RCO sites are not encumbered by development restrictions because no land has been acquired with grant money. The Yakima Cliffs/Umtanum Ridge ACEC proposed expansion area is crossed by the route
