area for that phase of mining. Topsoil is expected to range from 0-4 inches. The topsoil berm <br /> will be used during reclamation, will be constructed to 2H:I V slopes or shallower, and will be <br /> seeded within 180 days of pile establishment with native rangeland grasses to stabilize the <br /> topsoil stockpile until reclamation is in process. Variably thick overburden will be handled in the <br /> same fashion throughout the mine's life as topsoil detailed above. <br /> 5. Schedule of Operations <br /> Mining and processing will be conducted with portable equipment at various times of the year. <br /> Mining operations will be dictated by initial recovery values and market conditions. Mining may <br /> take place 7 days per week. Night mining will not occur, although minor truck activity or repairs <br /> may occur after daylight hours. <br /> 6. Montrose County Impacts and Environmental Impacts <br /> The impacts to Montrose County will be limited. No dust is expected from the operation as the <br /> active mine area and roads are watered as needed. In the event that airborne dust is observable, <br /> immediate action to mitigate dust via roadway wetting and a slowdown of production will be <br /> initiated and sustained until airborne dust is mitigated. Water used is pumped from the Dolores <br /> River and applied on an as-needed basis to control dust within the mine area. <br /> Noise and traffic will not significantly increase as the result of mining but will be mitigated to <br /> produce the lowest possible impact while continuing to operate. Noise will be limited to gold- <br /> bearing gravel processing and equipment backup alarms. As processing will be ongoing, noise <br /> from washing activities may exist; however, processing plant noise will only occur during hours <br /> of operation. No residential use properties are within 500 feet of the pit. <br /> Bancroft Placer Mine 4:rn I+ Iu and Aswriatvk FUA <br /> July 2020 C-6 <br />
