<br />topsoil should only remain for one [o two years. If the stockpile remains more than one growing <br />season, it will be seeded with wheatgrass to prevent erosion. <br />Topsoil will be replaced in reclaimed areas in the same six inch depth. <br />evegetation <br />The reclamation for this site will include water storage. Slopes will be no greater than 3:1. The <br />grasses were selected to be long lasting and regenerate themselves. The ground will be fine <br />graded and prepazed for seeding. Fertilizers will be used according to recommendations from the <br />Soil Conservation Services. <br />If a significant invasion of noxious weeds occurs, the azea will be mowed periodically for control. <br />Weeds will be mowed before they go to seed during the first growing season. Mechanical control <br />will be used as a first priority. Chemical methods will only be used if no other alternative <br />produces acceptable results. <br />As mining operations aze completed, the area will be graded and shaped. Runoff or excess water <br />from adjacent aeeas will not be allowed to Ilow over any of the slopes. Berms will be constructed <br />to divert this excess water and dispose of it in a safe non-erosive manner. <br />The seedbed will be worked up and be weed free and firm at the time of planting. If the seed is <br />broadcast, the seeding rates will be doubled. <br />Based on the soils in the azea, the following seeding mixtures aze recommended: <br />Vaughn Side Oats Grama <br />Grenville Switchgrass <br />Covington Blue Grama <br />Barton Western Wheatgrass <br />-OR- <br />Barton Western Wheatgrass <br />Luna Pubescent Wheatgrass <br />Lincoln Smooth Bromegrass <br />30% ].35 #PLS/ac. 3c`L` <br />20°Jo 0.5 #PLSlac.l~l0 <br />20% 0.3 #PLS/ac.

The seeded areas <br />will then be covered with straw mulch, at a rate of 4,000 pounds per acre. The straw will be <br />crimped into the soil to control erosion until the grass becomes established. Seeding will be done <br />between November 1 and May 1 and as soon as fine grading is completed. <br />Cattle and horses will not be grazed on the revegetated areas for at least two years so the grasses <br />can become established. <br />River View Resource, CAMAS Colornda. /nc. <br />DMC ll1 Permit <br />Page 8 <br />
