Please find attached a letter from W.W. Wheeler summarizing their <br />review of this project and maps indicating the proposed location of the crossings. This <br />request is in addition to the request made two years ago (October 2000) for a temporary <br />logging crossing. These new crossings are necessary to support our ongoing topsoil <br />salvage program. The relocation of several topsoil stockpiles will be necessary next <br />summer to avoid inundation. Henderson plans to relocate these stockpiles to the north <br />Area 21 per our approved reclamation plan. <br />Please note that these crossings will not be sized for the probable maximum snowmelt. <br />The size culvert to accommodate these flows, near the north abutment of #1 Dam, will <br />not fit in the existing canal without a major widening of the associated access road. <br />Therefore, Henderson proposes to install temporary arch culvert crossings that could be <br />removed quickly if an extreme snowmelt run-off is anticipated. Time permitting, <br />Henderson will begin constructing the new crossings and haul roads this fall. However, <br />we do not anticipate they will be completed until next spring. Henderson is also planning <br />on developing the south Area 21 topsoil stockpile location in the near future to facilitate <br />the relocation of topsoil from the southeast corner of the tailing pond. Henderson <br />assumes the previous permission granted by the Division, for a temporary logging <br />crossing on the upper portion of the interceptor canal, would still be valid pending <br />notification to the Division of the proposed location of the crossing(s). <br />
