Division of Reclamation Mining&Safety <br /> Permit Application <br /> 6.3.3 (d) <br /> • Mining thickness 4' +/-ranges from 1' —4' <br /> 6.3.3 (e) <br /> • All roads are pre-existing,no pits, structures or other facilities <br /> 6.3.3 (f) <br /> • See Mining exhibit for dimensions. <br /> • Three primary borrow locations: Southern location identified and existing conditions had slopes <br /> 1:1 or steeper. Borrow materials were removed and from an area 110'x30' from 0-3' in depth. <br /> Slopes were regraded to 3:1 or flatter and until they were deemed stabile by Geotechnical engineer. <br /> • Location 2: is the middle adjacent to the Mary Ann Sink Trust"Western Fence"in an area 100'x30' <br /> varying in depth from 0-3' Slopes were re-contoured to a 3:1 or flatter and until they were deemed <br /> stabile by Geotechnical engineer. <br /> • Location 3: is the North Western location and is approximately 130'x180' varying in depth from <br /> 04'. Slopes were re-contoured to a 3:1 or flatter and until they were deemed stabile by <br /> Geotechnical engineer. <br /> • Existing drainage was not modified, and all flows remain directed to same drainage pattern pre- <br /> mining. <br /> • No changes or modifications were made to increase or influence existing hydrology. The surface <br /> area of accumulation remains the same as pre-mining operations. <br /> 6.3.3 (g) <br /> • See mining exhibit for existing roads <br /> • No improvements <br /> • Access to the permitted site was an existing, ungraded dirt road varying in width from 12' — 16' <br /> with wheel ruts up to 6" No improvements or modifications were made to the existing road within <br /> permitted boundries <br /> 6.3.3 (h) <br /> • No water uses <br /> 6.3.3 (i) <br /> • N/A no groundwater <br /> • The borrow locations were graded to direct surface drainage and flow to existing ditches where all <br /> water previously flowed. The ditch will be protected with a sediment pond to allow sediment to be <br /> maintained within the permitted limits <br /> 6.3.3 0) <br /> • N/A <br /> 6.3.3 (k) <br /> • None <br /> 6.3.3 (1) <br /> • Grading was and will be re-established to concentrate any runoff or flow from mining operations <br /> to a centralized sediment pond that will be approximately 15' across with a sediment ponding area <br /> in excess of 25'x20'x4' developed from onsite earthen materials and straw logs.
