limits. The slope will then be laid back to the 3H:1 V slope. The slopes will be backfilled with <br />either overburden or material excavated from the shelf wetlands. Ramps into the pits will be <br />left as shallow 7H:1 V sloped areas. To minimize final reclamation tasks, slopes will be <br />backfilled promptly after mining is complete. <br />Creation of wetland shelves will be completed using dozers or excavators to remove material <br />from the shelf area. Material will be removed to the depth of the water table and topsoil will be <br />replaced to a thickness of 12 inches. The lateral extent of the shelf will extend from the lake <br />edge to a 5-foot buffer from the existing wetlands. This buffer will prevent disturbance to the <br />adjacent wetlands. Also during the excavation of the shelves existing cottonwoods and willow <br />bunches will be left intact. See Map F-3 for shelf and fringe details. <br />Re-Topsoiling Plan <br />Topsoil will be replaced in all disturbed areas to a minimum depth of 12". It is expected that <br />more than 12" of topsoil will be available due to the lake areas not needing topsoil. If this is <br />the case additional topsoil will be placed in the disturbed areas. The topsoiling will occur to <br />five feet below the expected water table. <br />Revegetation Plan <br />The site will be revegetated as follows: <br />Dry Rangeland The following seed mix is recommended for the upland dry <br />rangeland areas. After regrading, the reclaimed area should be <br />tilled. The seed mix can then be broadcast and mulch applied over <br />the seeding, The mulch will be crimped in at a rate of 1.5 <br />tons/acre. Only certified weed free mulch will be used. <br />Species <br />Palome Indian Ricegrass <br />Ephraim Crested Wheatgrass <br />Canbar Canby Bluegrass <br />Sodar Streambank Wheatgrass <br />Canada Wildyre <br />Slender Wheatgrass <br />Fourwing Saltbush <br />Rabbitbrush <br />Skunkbush Sumac <br />Total <br />Lbs/acre Seed, PLS <br />6.0 <br />3.0 <br />1.0 <br />3.0 <br />2.5 <br />2.5 <br />0.3 <br />0.3 <br />0.3 <br />18.9 <br />7/22/04 Page E-2 <br />
