Vantage to Pomona Heights Chapter 3 <br />230 kV Transmission Line Project FEIS Affected Environment <br /> PAGE 3-268 <br />3.12.4.10 Route Segment 3c <br />The Incident #243 fire perimeter is just within the Project study area for Route Segment 3c. The Incident <br />#243 fire burned over 1,300 acres in 2008. The most common vegetation types for Route Segment 3c are <br />sagebrush/perennial grassland (42 percent), agriculture (33 percent), and annual grassland (19 percent). <br />BPA’s Shultz-Wautoma 500 kV line and the Midway-Vantage 230 kV line cross this route segment. <br />Three additional BPA lines are within the Project study area, but do not intersect this route segment. The <br />majority of Route Segment 3c is classified as FRCC 2 (30 percent) or FRCC 3 (27 percent) and is within <br />Fire Regime Group III (74 percent). <br />3.12.4.11 Route Segment NNR-2 <br />Vegetation along Route Segment NNR-2 is composed primarily of annual grassland (48 percent), <br />sagebrush/perennial grassland (24 percent), and agriculture (22 percent). Approximately two miles of <br />Route Segment NNR-2 parallels an existing JBLM YTC fire break road, existing roads, and an existing <br />transmission line. Vegetation along the fire break is disturbed and dominated by non-native species <br />including cheatgrass. Small fires occurred east of Route Segment NNR-2 within JBLM YTC in 1989, <br />1990, and 2003. The majority of Route Segment NNR-2 is classified as FRCC 2 (50 percent) and FRCC 3 <br />(14 percent) and is within Fire Regime Group III (84 percent). <br />3.12.4.12 Route Segment NNR-3 <br />Vegetation along Route Segment NNR-3 consists primarily of intact sagebrush/perennial grassland (50 <br />percent) and annual grassland (44 percent). Route Segment NNR-3 crosses within 0.5 mile of the eastern <br />edge of the Canyon #1 fire that burned on BLM land in 1997. The majority of Route Segment NNR-3 is <br />classified as FRCC 2 (56 percent) and FRCC 3 (22 percent) and is within Fire Regime Groups III (61 <br />percent) and IV (36 percent). <br />3.12.4.13 Route Segment NNR-4 <br />Route Segment NNR-4 is comprised primarily of sagebrush/perennial grassland (69 percent), with lesser <br />amounts of annual grassland (17 percent), agriculture (seven percent), and perennial grassland (four <br />percent). Fire history records indicate that two fires have occurred within the Project study area of Route <br />Segment NNR-4, both within JBLM YTC. The first fire was located just north of Route Segment NNR-4 <br />and occurred in 2002. The second fire occurred south of Route Segment NNR-4 in 2010. The majority of <br />Route Segment NNR-4 is classified as FRCC 2 (45 percent) and FRCC 3 (28 percent) and is within Fire <br />Regime Groups III (52 percent) and IV (48 percent). <br />3.12.4.14 Route Segment NNR-5 <br />Vegetation along this short route segment consists primarily of intact sagebrush/perennial grassland (67 <br />percent), with lesser amounts of agriculture (20 percent) and forb (11 percent). Annual grassland <br />contributes less than one percent. Fire history records indicate that no recent fires have occurred along <br />Route Segment NNR-5. The majority of Route Segment NNR-5 Project study area is classified as FRCC <br />2 (40 percent) and FRCC 3 (20 percent), and is within Fire Regime Groups III (55 percent) and IV (45 <br />percent). <br />3.12.4.15 Route Segment NNR-6 <br />Vegetation along this route segment consists primarily of intact sagebrush/perennial grassland (78 <br />percent), with lesser amounts of forb (12 percent), perennial grassland (five percent), and agriculture (five <br />percent). Annual grassland contributes less than one percent. Three fires have occurred within JBLM <br />YTC along Route Segment NNR-6. In 2014, a 23,261-acre fire burned within the JBLM YTC boundary, <br />along and north of Route Segment NNR-6. In addition, a large fire occurred north of Route Segment <br />NNR-6 in 2008 and a second, smaller fire, also occurred north of the route segment in 2001. The majority <br />of Route Segment NNR-6 is classified as FRCC 1 (32 percent) and FRCC 2 (38 percent) and is within <br />Fire Regime Groups III (42 percent) and IV (58 percent).
