Added 5-21-82 <br />The second type of light-use road is the pit road. Pit roads will <br />be constructed to provide access into and around the working pit. They <br />will be constructed as they become necessary and will be reclaimed <br />shortly after they are no longer needed. <br />All the light-use roads on the Bourg property have been or will be <br />constructed using the best technology available to minimize the impacts <br />on fish, wildlife, and related environmental values. They will be <br />located on stable, gently rolling slopes, out of stream channels, and <br />away from any wet, steep or unstable areas. <br />Vegetation and topsoil were removed from an area no greater than one <br />lane wide prior to construction of light-use roads. These roads were <br />field designed according to Mined Land Reclamation criteria. Maximum <br />grade is less than 1v:lOh (10%) and the roads meander to follow natural ~ <br />variation in topography and vegetation. <br />Flowing drainages shall not be forded and natural channel drainage <br />ways shall not be altered by construction and use of any of the pit roads. <br />The perimeter road crosses Mann Draw at two points on the Bourg property. <br />• Since this section of road is seldom used, and Mann Draw will not be <br />forded while it is flowing, the erosion effects of these crossings shall <br />be negligible. The perimeter road also crosses one culvert, which is.adequate <br />to handle outflow from sediment pond B. Any sedimentation that occurs <br />as a result of construction and use of light-use roads will be handled <br />by the sediment control ponds on the Bourg property. <br />All light-use roads will be surfaced using materials available on-site. <br />No toxic- or acid-forming materials shall be used to surface these roads. <br />i <br />Maintenance of light-use roads will be adequate to ensure that erosion <br />will be minimized and the perimeter road will not be used during heavy <br />rainfall or extreme snowmelt conditions where erosion might be significant. ; <br />Roads shall be closed to all vehicular traffic when they are no <br />longer requried for operations, reclamation, or monitoring purposes. <br />~s They will then be regraded to conform to the natural surroundings and <br />topsoiled and reseeded in the same manner as other disturbed areas on <br />the Bourg site. <br /> <br />D-9(b) <br /> <br />
