representative for inspection. Any proposed changes in the Exploration Plan after permit approval will be reviewed with the appropriate regulatory agencies before changes take effect. Camp sites and /or staging areas to be used by the drilling contractor will be reviewed with and approved by the USFS District Ranger or authorized representative prior to use. These sites will be used in a manner to minimize damage to the vegetation. Any surface disturbance to these sites will be reclaimed and reseeded. Road Const - uction Existing roLds and trails will be used whenever possible, and movement of equipment across undisturbed land will be kept to a minimum. New or additional roads will be constructed only when necesj;ary and only as the drilling program progresses. A projected maximum of 14 ft. road service width will be employed during this project except in locations such as curves, where more width would be needed for the drill rig to negotiate a turn. The drill sites have been located such that the slope of the access roads to the pad sites will be as flat lying as possible and subject to vary only a few percent. Topsoil removed during pad construction will be stockpiled and redistributed when the pads are reclaimed. Erosion control structures, such as water bars, will be installed as required and will be constructed in accordance with applicable regulations and stipulations. Waterbars while in use, will be left in -place along the road to assist in erosion control. If utilized, culverts will be removed at the completion of the project or left in place as accepted by the USFS Road Engineer. Drill Site C nstruction Drill sites vi11 be approximately 100' x 200' in size. Smaller dimensions will be utilized whenever p ssible. Drill site sizes and layout will be reviewed with the USFS representative prior to contruction. Brush and /or small trees will be cleaned from the drill pads using a D -7 or similar size equipment. Available topsoil will be removed and stockpiled on the upslope side of the drill pad and remain undisturbed during drilling at the site. The topsoil pile will not be seeded due to the short duration of storage. Up to one foot of topsoil thickness will be salvaged and stockpiled at the disturbance site with a "TOPSOIL" sign clearly marking the pile. Leveling of the drill sites (cut and fill) by grading the subsoil and /or weathered rock may be required. Slurry (mud) pit construction will be made on the downslope portion of the prepared drill pad. Using a D -7 dozer, track hoe, and backhoe, from one to two pits will be excavated at each site, depending upon depth of drill hole and projected water requirements. The mud pit(s) will be approximately 10' wide, 30' long and 6' deep. Subsoil and rock materials excavated from the pits will be stockpiled and used to refill the mud pits upon reclamation. All pit constructions and stockpiled subsoil will be within the stripped pad area. The hydrologic balance will be protected by minimizing disturbance and through sediment control from exploration activities. Using the existing roads or trails to the degree practical minimizes surface disturbance. Where possible, the existing vegetation will be left in -place and the need for sediment control therefore reduced. With the existing roads mainly located in the flatter areas (along the ridge tops or valley bottoms), the need for new disturbance and the possibility of sediment loss is reduced by avoiding areas of steep slopes. Likewise, by utilizing 8
