Table E-1 shows the grass species recommended by the United States Department of <br />Agriculture Natural Resources Conservation Service to be used to reseed the gravel pit <br />site and to provide temporary cover on the stock piled topsoil. Native shrubs are expected <br />to invade the site in relatively short time after the pit closure. <br />Table E-1 <br />SEED MIX IN POINDS OF PURE LIVE SEED PLS PER ACRE <br />Species Variety Pounds PLS/Acre <br />Western Wheatgrass Arriba 3.2 <br />Thicks ike Wheatgrass Critana 2.2 <br />Streambank Wheatgrass Siberian 2.2 <br />Russian Wildrye Vinal 2.0 <br />Crested Wheatgras s E hriam 2.0 <br />Total Pounds PLS/Acre 11.6 <br />3. Post-Reclamation Site Drainage <br />The drainage will primarily have the same direction as the pre mining, which is primarily <br />in a northerly direction. <br />4. Weed Control <br />Proper and adequate weed control measures will be necessary the first two years, to <br />ensure the establishment of a sufficient stand of grass and prevent the invasion of weeds, <br />especially noxious weeds. If weed competition is reduced the opportunity for grass <br />establishment is increased significantly. Appropriate herbicides should be applied the <br />first growing season during the early spring and summer to control weeds if present. The <br />herbicide label should be followed. The site should have all livestock excluded for a <br />minimum of one and preferably two growing seasons after planting to allow the best <br />opportunity for the seeded species to become established. <br />5. Revegetation Success Criteria <br />The area will be deemed adequate when the vegetation has bee established in order to <br />control erosion and noxious weeds are not present in any significant amounts and all of <br />the conditions of Rule 3.1.10 of the Division of Reclamation, Mining and Safety <br />Construction Materials Rules have been met as determined by the Division of <br />Reclamation and Safety. <br />14
