determined more reasonable than the West Route. Shifting the southern segment of the East Route south
of the sage-grouse lek and buffer (BA13-MA2 revised to BA13-BA14-BA16-MA2) resulted in the lek
being screened by existing topography but did not change the route’s construction and engineering
difficulty. As a result, the (revised) East Route, BA10-BA11-BA13-BA14-BA16-MA2 (comprising CAP
routes C4, C8, C41, S9, and S19) was recommended as more reasonable than the West Route, BA10-
BA20-MA1-MA2 (CAP routes S20 and S21).
