TOPSOIL REPLACEMENT -Topsoil replacement will occur using mobile equipment once all re-grading <br />of the area disturbed by mining is complete. Topsoil will be replaced to a thickness of at least 8 inches, <br />which is appropriate to establish vegetation communities consistent with the post mine land use. <br />RE-VEGETATION -The intent of the re-vegetation is the establishment of plant communities consistent <br />with the post-mine land use. After topsoil replacement, seed bed preparation and stabilization will be <br />conducted and may include one of the following: ripping, disking, harrowing and/or furrowing. Because of <br />the phased fashion in which the site is mined and reclaimed, it will allow for continuous analysis of re- <br />vegetation success and determining the best type of preparation that should be used. <br />Seeding recommendations, contained within the initial application, follow: <br /> <br />Shee Fescue 1.5 #PLS/Ac. <br />Crested Wheat rass 1.5 #PLS/Ac. <br />Thicks ice Wheat rass 2.0 #PLS/AC. <br />Slender Wheat rass 2.0 #PLS/AC. <br />Pubescent Wheat rass 1.0 #PLS/Ac. <br />Orchard rass, Paiute 1.5 #PLS/Ac. <br />Winter Wheat 1.0 #PLS/Ac. <br />TOTAL 15.0 #PLS/Ac. <br />Seeding will nonnally be done in the fall andlor spring when temperatures and adequate soil moisture are <br />present. Seeding will be accomplished by either broadcasting, or by using a seed drill. If broadcasting is <br />used, seed rates will be doubled. Due to the nature of the backfill material and topsoil found in the area, <br />hay, straw or fiber mulch is considered to be necessary. Mulching will be accomplished with a clean <br />certified weed free straw at a rate of 2000 pounds per acre either crimped or "tacified" at 150 pounds per <br />acre. "Biosol" fertilizer will be applied at a rate of at least 1000 pounds per acre. <br />• • <br />Material Rate/Ac. <br />"Biosol° Fertilizer 1000 lbs. <br />Fiber Mulch 200 lbs. <br />Tackifier 2001bs. <br />Straw Mulch a rox. 100 bales <br />WEED CONTROL - If necessary, weed control measures will be employed for control of any noxious <br />weed species. Control measures will also be used if the growth of weed species on the reclaimed area <br />threatens further spread of the weeds to nearby areas. In the event that weed control is required, <br />herbicides will be of those that are approved by the Soil Conservation Service and applied by a licensed <br />herbicide applier. A Weed Control Plan will be utilized as follows: <br />^ Asemi-annual inspection of all disturbed areas by trained weed control personnel. <br />^ Treat any identified infested areas with herbicide recommended by the local weed control <br />authorities. <br />^ Inspect the infested area after 2 weeks and re-apply herbicide as required. <br />^ Inspect the site at 4-week intervals after the second inspection and re-treat as required. <br />^ Any weed control refuse left from previous year's growth will be burned on site. <br />
