Surface disturbance during the construction phase will obviously <br />be signficant since trenches must be dug and wells drilled, but <br />the narrowness of the corridor and expansive nature of habitat <br />for the terrestrial vertebrates minimize this impact. <br />Obviously, revegetation of the area over the buried pipeline <br />will be slow, particularly in the nonriparian habitats, but will <br />not be a factor in population stability. The xater withdrawal <br />method will temporarily disturb the riparian habitat along the <br />White River during drilling and construction but once installed <br />surface disturbance will be of little consequence. <br />Loos of habitat will be minimal and/or shortlived. It should be <br />• of no serious consequence. <br />Hoise during construction and operation of the pipeline warrants <br />concern. During construction many of the terrestrial <br />vertebrates, particularly those that might reproduce in the <br />immediate vicinity of the corridor, will fail to reproduce, <br />eaperience-reduced reproductive effort or will temporarily leave <br />the area. Perhaps individuals xill not return to the area, but <br />the species undoubtedly xill return after the pipe is buried and <br />construction finished. An eaception to this might occur at the <br />withdrawal sites, but this is doubtful. Continuous operation of <br />the pumps will make noise, but the noise will be muted by the <br />subsurface pump housing.
