<br />RECLAMATION PLAN EXHIBIT D <br />6.3.4 - Final grading will be such that the topography is <br />appropriate to the reclaimed use of the property, i.e., as <br />rangeland. Slopes will be graded to, 3h to lv from top to <br />bottom. The floor of the mine will have a gentle slope to the <br />southwest so it is consistent with existing grades. The Reclamation <br />Plan Map -Exhibit E-2 on the MAP PLAT shows how we think the area will <br />look when it is reclaimed. <br />Seeding will occur after October 15th and before April 15th <br />or after the first freeze and before the first frost. Seeds will <br />be drilled to insure maximum germination and most rapid cover <br />establishment. The seeding mix and species of grasses for the <br />area are shown on page 5 of this report. This is a seed mixture <br />made up of native grasses found on the site that has been used <br />successfully on other county gravel mines. We will obtain the <br />seed from a supplier in the area so the mix is adapted to local <br />conditions. We also expect to see a natural invasion of forbs <br />and woody plants from surrounding areas. <br />If this seed mix is not used, we will notify the Division of <br />what mix will be planted and give our rational for changing the <br />mix in the annual report following the change. Only inaccessible <br />areas (if any) will be broadcast seeded. Zf the seed is broad- <br />cast, the seed rates will be doubled. No mulch will be used on <br />the area. No trees or shrubs will be planted at this time. <br />Reclamation will begin by replacing the salvaged topsoil on <br />the excavated area. We estimate the average depth of the re- <br />placed topsoil will be 10 inches. Once recoiling begins the <br />topsoil/growth medium will be removed from the stockpiles and <br />spread over the slopes. if fertilizer is use it will be spread <br />on the seedbed and disced in during seed bed preparation and just <br />prior to planting. Once seeded the area will be monitored for <br />reclamation success. The seeded area may be fenced with a single <br />strand of electrical wire if cattle are placed on the surrounding <br />range. After the second growing season the site will be in- <br />spected and an assessment of revegetation success will be done to <br />determine if additional seeding will be necessary. If the <br />analysis shows additional work is needed it will done that fall. <br />Weed control will be implemented prior to and during <br />revegetation activities. This does not mean we will attempt to <br />kill all weeds, since some provide a natural ground cover and <br />shade for emerging grass. We will concentrate on controlling the <br />noxious weeds on the reclaimed area, following NRCS recommenda- <br />tions if a problem occurs. <br />10 <br />
