Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-38 Table 3.2-1). Within one mile of Route Segment NNR-6, forbs (e.g., narrowleaf mock goldenweed and thyme-leaf buckwheat) are also present on approximately 1,206.6 acres (11.8 percent). The Route Segment NNR-6 ROW crosses several un-named intermittent or ephemeral drainages. A section of this route segment parallels Foster Creek and is within 0.4 mile at its closest location. The ROW for Route Segment NNR-6 also parallels Johnson Creek. At its nearest point, Johnson Creek lies approximately one mile south of Route Segment NNR-6. Both Foster and Johnson Creeks are perennial streams and contain forested riparian vegetation. WNHP data indicate that Suksdorf’s monkeyflower intersects Route Segment NNR-6 and that beaked cryptantha, caespitose evening-primrose, coyote tobacco (Nicotiana attenuata), longsepal globemallow (Iliamna longisepala), and snowball cactus all are known to occur within one mile of Route Segment NNR-6 (Table 3.2-5). Route Segment NNR-6’s ROW is comprised entirely of federal lands; however, surveys were not conducted along the entire length of this route segment’s ROW due to route adjustments made following the completion of plant surveys (Table 3.2-3). Approximately 95.7 acres of suitable habitat, 21.9 acres of marginal habitat, and 0.0 acres of unsuitable habitat is present within this route segment’s ROW (Table 3.2-6). No priority ecosystems are known to occur within five miles of Route Segment NNR-6. No noxious weeds are known to occur along Route Segment NNR-6’s ROW; however, the entirety of this route segment was not surveyed due to route adjustments made after noxious weed surveys occurred. 3.2.4.16 Route Segment NNR-7 Route Segment NNR-7 is located on the northeastern side of JBLM YTC and parallels the existing Pacific Power Pomona-Wanapum 230 kV Transmission Line. The majority of vegetation within this route segment’s Project study area consists of the sagebrush/perennial grassland cover type (11,931.4 acres, 95.3 percent; Table 3.2-1). The ROW for Route Segment NNR-7 crosses several un-named intermittent or ephemeral drainages. Route Segment NNR-7 also parallels Johnson Creek. At its nearest point, Johnson Creek lies approximately one half mile south of Route Segment NNR-7. Johnson Creek is perennial and contains forested riparian vegetation. Eleven special status species are known to occur within the Route Segment NNR-7 Project study area. WNHP data indicate Route Segment NNR-7 intersects occurrences of beaked cryptantha, bristle-flowered collomia, caespitose evening-primrose, dwarf evening-primrose, gray cryptantha, miner’s candle, and Suksdorf’s monkeyflower. In addition, WNHP data indicate that Columbia milkvetch, naked-stemmed evening-primrose, white eatonella, and snowball cactus are known to occur within one mile of Route Segment NNR-7. Special status plant surveys were conducted along this route segment. However, adjustments were made to the preliminary route to decrease separation distances between the proposed Project and an existing 230 kV line; therefore, the current ROW was not surveyed (Table 3.2-5). Approximately 1.6 percent (2.4 acres) of federal and WSDOT lands within this route segment’s ROW were surveyed for special status plants (Table 3.2-3). Approximately 149.9 acres of suitable habitat, 0.0 acres of marginal habitat, and 0.1 acre of unsuitable habitat is present within this route segment’s ROW (Table 3.2-6). Three priority ecosystem types are located within five miles of Route Segment NNR-7: Antelope bitterbrush-Indian ricegrass, Intermountain Basins Active and Stabilized Dune, and Wyoming big sagebrush-needle and thread grass (Table 3.2-7). Two noxious weed species are known occur in Route Segment NNR-7, but are not mapped. Burningbush was present but not mapped because of its abundance and frequency of occurrence within the Route Segment NNR-7 ROW. In addition, a portion of this route segment was not surveyed due to route adjustments made after noxious weed surveys occurred (Table 3.2-2; Appendix B-4 - Noxious Weed Reports).
