Work will commence in September 1987 and be <br /> completed before winter weather ends the field <br /> construction season at high altitude . Additional <br /> gravel production by screening may be required in <br /> subsequent summers. <br /> Exploration drilling will also be conducted in the <br /> Sunnyside Basin during the summer season. Roughly <br /> fourteen drill sites are anticipated to be used during <br /> 1987. Eleven lie on patented mining claims, while <br /> three are located on public land . <br /> PROPOSED DISTURBANCE <br /> Disturbance for gravel production will be limited <br /> to dozing a temporary road and gravel screening within <br /> the previously disturbed areas of the Sunnyside Basin. <br /> The areas potentially to be disturbed are at an eleva- <br /> tion of 12 ,200 to 12,360 feet mean sea level (FMSL) , <br /> and no topsoil is present . All areas to be disturbed <br /> lie within the current permit boundaries, and potential <br /> borrow areas and access routes are shown on Exhibit Cl . <br /> Disturbance for exploration drilling will consist <br /> of 1) road widening at drill sites lA and iB; 2) road <br /> and drill pad filling at sites 3A, 3B, and 3C; and <br /> 3) two track access and drill pad dozing at sites <br /> 7 <br /> -2- �' <br />
