Road Construction <br />Existing roads and trails will be used whenever possible, and movement of equipment across <br />undisturbed land will be kept to a minimum. New or additional roads will be constructed only <br />when necessary and only as the drilling program progresses. A maximum of 15 ft. road width <br />will be employed during this project except in locations such as curves, where more width would <br />be needed for the drill rig to negotiate a turn. <br />The drill sites have been located such that the slope of the access roads is nearly flat lying and <br />subject to vary only a few percent. All topsoil removed during pad construction will be <br />stockpiled and redistributed when the pads are reclaimed. Erosion control structures, such as <br />water bazs, will be installed as required and will be done in accordance with applicable <br />regulations and stipulations. Waterbars will be left in-place to assist in future erosion control. If <br />utilized, culverts will be removed at the completion of the project or as accepted by the USFS <br />Road Engineer. <br />Drill Site Construction <br />Drill sites will be approximately 100' x 200' in size. Smaller dimensions will be utilized <br />whenever possible. Drill site sizes and layout will be reviewed with the USFS representative <br />prior to construction. Table 2 lists the estimated amount of disturbance. <br />• Brush andlor small trees will be cleaned from the drill pads using a bulldozer. Topsoil will be <br />removed and stockpiled on the upslope side of the drill pad and remain undisturbed during <br />drilling at the site. The topsoil pile will not be seeded due to the short duration of storage. <br />Approximately one foot of soil thickness will be salvaged and stockpiled at the disturbance site <br />with a "TOPSOIL" sign clearly marking the pile. Leveling of the drill sites (cut and fill) by <br />grading the subsoil and/or weathered rock is not anticipated. <br /> <br />Slurry (mud) pit construction will be made on the downslope portion of the topsoil stripped drill <br />pad. Using either a D-6 dozer or backhoe, from one to two pits will be excavated at each site, <br />depending upon depth of drill hole and projected water requirements. The mud pit(s) will be <br />approximately 10' wide, 30' long and 6' deep. Subsoil and rock materials excavated from the <br />pits will be held sepazately and used to refill the mud pits upon reclamation. All pit constructions <br />and extracted subsoil will be within the stripped pad area. <br />The hydrologic balance will be protected by minimizing disturbance and through the entrapment <br />of sediments from exploration activities. Using the existing roads or trails to the degree practical <br />minimizes surface disturbance. Where possible, the existing vegetation will be left in-place and <br />the need for sediment control therefore reduced. With the existing roads mainly located in the <br />flatter azea (along the ridge tops or valley bottoms), the need for new disturbance and the <br />possibility of sediment loss is reduced by avoiding areas of steep slopes. Likewise, by utilizing <br />existing flat azeas for drill pads, only minimal surface disturbance will be necessary to level <br />uneven portions of the site and to construct a mudpit. <br />l0 <br />
