If approved, future <br />reclamation of the mine site will be completed to reclaim the affected land to a lined water <br />storage reservoir. We offer the following general information that pertains to many sand and <br />gravel mines in the Platte River drainage. It addresses recommended handling of topsoil and <br />overburden, reservoir fittal reclaimed slopes, reclamation re-vegetation and recommended seed <br />mix. <br />Topsoil and Overburden Stockpiles <br />The NRCS recommends that topsoil stockpiled for reclamation be segregated from other spoil. <br />The topsoil and overburden stockpiles should be graded with final slopes preferably no steeper <br />than 4H:1 V. Slopes the! aze less steep allow easier maintenance, are less susceptible to water <br />erosion and more readily establish grass protective cover. <br />It is highly recommended that topsoil and overburden stockpiled over 30 days be seeded <br />immediately as weather permits to protect the soil. The immediate seeding of these stockpiles <br />should be done to avoid soil erosion from wind and water, as well as from a weed standpoint. <br />Weeds are very invasive and nave omo disturbed areas very quickly. Some of these can be <br />noxious weeds and require control based on the state noxious weed list. Through immediate <br />seeding to promote temporary cover, the opportunity for weed invasion will be less, as will the <br />potential for erosion. For seeding the stockpiles, Luna pubescent wheatgrass and/or Amur <br />intermediate wheatgrass aze recommended, both of which wt71 establish readily and quickly. <br />This temporary seeding should be done at a rate of 15 total pounds PLS per acre. <br />The Natural Resources Conservation Service provides leadership in a partnership effort to help people <br />COnflrvl, maintain, drld improve W f natural leSOUrCeS and MvirOnrnMt <br />An EQUeI Opportunity Provider and Employer <br />
