Excavations, including mud pits, will be backfilled. Where mud pits are necessary, theywill be allowed to dry <br />and/or backfilled with drill cuttings and/or previously excavated material. Duxing backfilling, the material <br />will be mixed and compacted as it is replaced, by running the equipment over the backfilled area during <br />placement of successive lifts. Following backfilling, disturbance areas will be graded to their approximate <br />original configuration and drainage will be reestablished. Any salvaged topsofl materials will be re-spread <br />onto the regraded surface. A metal post will be placed in the vicinity of the hole as a permanent marker. All <br />trash and debris will be removed from drill sites for disposal. <br />For pre-existing disturbance areas, the disturbed configuration will be reestablished as needed for future <br />operations. For other exploration disturbance areas, reclamation will be completed after regrading by <br />scarifying the regraded surface as needed, redistributing stockpiled topsoil, and reseeding the area using the <br />following seed mixtures: <br />Species <br />Westem wheatgrass <br />Slender wheatgtass <br />Bluebunch wheatgrass (beardless) <br />Sandberg bluegrass <br />Mountain brome <br />Sheep fescue <br />Westem yarrow <br />Cicer milkvetch <br />Lewis flax <br />Rocky Mountain penstemon <br />Sanfoin <br />Total (PLS lbs/ac) <br />0.08 <br />0.8 <br />0.5 <br />0.4 <br />1.0 <br />10.88 <br />On USFS lands the following seedmix will be used: <br />Species Broadcast Seeding Rate (lbs PLS/acre) <br />Mountain Brome - Brornar 4.0 <br />Prairie Junegrass 0.5 <br />Westem Wheatgrass - Amba 4.0 <br />Indian Ricegrass 1.0 <br />Sanberg Bluegrass 3.0 <br />Bluebunch Wheatgrass (beardless) 3.0 <br />penstemon strictus 0.3 <br />Achilles millefolium v. occidentalis 0.1 <br />Total (PLS lbs/ac) 15.9 <br />On BLM lands the following seed mix will be used: <br />Species <br />Mountain Brome - Brornar <br />Slender Wheatgrass -San Luis <br />Westem Wheatgrass - Amba <br />Big Bluegrass - Shem~art <br />Canada Wildrye <br />Rocky Mm. penstemon <br />Broadcast Seedine Rate (lbs PLS/acre <br />2.0 <br />1.4 <br />2.0 <br />0.3 <br />1.2 <br />1.2 <br />Broadcast Seeding Rate (lbs PLS/acre) <br />3.0 <br />1.5 <br />2.0 <br />0.5 <br />2.0 <br />0.3 <br />
