topsoil berm,which will eventually be used during reclamation,will be constructed to 2H:1 V <br /> slopes or shallower,and will be seeded within 90 days of establishment with native rangeland <br /> grasses to stabilize the topsoil berm until reclamation is in process. Variably thick overburden <br /> will be handled in the 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 market conditions. Mining may take place 7 days per <br /> week. Night mining will not occur,although minor truck activity or repairs may occur after <br /> 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 imported via truck from <br /> Nucla 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 gravel <br /> processing and equipment backup alarms. Processing plant noise will only occur during hours of <br /> operation.No residential use properties are within 500 feet of the pit. <br /> No impacts are expected to the operations at Hopkins Field. <br /> Weimer Ranches #4 <br /> June 2021 C-5 <br />
