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 rangeland. <br />The overall slope of the mine face will be left at the 1.33:1 rate or <br />15 foot vertical faces joined by 20 foot wide benches. The floor of <br />the mine have a slight grade to preserve the natural drainage on the <br />site per the landowners wishes . The Reclamation Plan Map -Exhibit E-2 <br />shows how we envision the area will look when it is reclaimed. <br />Reclamation will begin as the exterior limit of the mine is <br />reached. As mining is completed on each bench, the finished flat <br />area will be resoiled using any salvageable soils and seeded. Where <br />they exist a stable bench faces will be left that needs no reclama- <br />tion. Once mining is done on an area and will not be disturbed again <br />it will be resoiled and prepared for seeding. We estimate the <br />average depth of the replaced topsoil will be 1-2 inches deep since <br />very little soil exist on the site. <br />The seeding mix and species of grasses to be used on the area <br />are shown on page 4 of this report. This is a seed mixture required <br />by the USFS and is made up of native grasses and forbs that has been <br />used successfully on the Routt National Forest. The seed will be <br />obtain from a local supplier in the area so the mix is adapted to <br />local conditions. We also expect to see a natural invasion of trees, <br />forbs and woody plants from surrounding areas. Grand County will <br />work with the USFS on restoring trees on the site. At this time we <br />do not know if seedling trees or seed will be used. <br />Fertilizer will be used to enhance the seed bed and the area <br />will be hydromulched per the USFS requirements. A mixture of grass <br />seed (35#/ac), a fertilizer mix of 18°s Nitrogen and 46% Potassium <br />(250#/ac), Fibermulch (400#/ac) and water (1450 #/ac) will be used to <br />seed the prepared seedbed. <br />Seeding will occur in the fall (after October 1St) or the spring <br />after the last freeze but before May 1St. Revegetation will be <br />carried out in such a way, so as to establish a diverse, effective <br />and long-lasting vegetative cover that is capable of self-regenera- <br />tion without continued dependence on irrigation, soil amendments or <br />fertilizers. The plan is to create a vegetative cover that is at <br />least equal in extent to the cover of the natural vegetation before <br />mining. <br />The landowner will be asked to avoid disturbing the site during <br />the first three years to insure the seed takes. After the second <br />growing season the site will be inspected and an assessment of <br />revegetation success will be done to determine if additional seeding <br />will be necessary. If the analysis shows additional work is needed <br />it will done that fall. <br />Weed control will be implemented prior to and during revege- <br />tation activities. This does not mean we will attempt to kill all <br />weeds, since some provide a natural ground cover and shade for <br />emerging grass. We will concentrate on controlling the noxious weeds <br />on the reclaimed area, following NRCS recommendations if a problem <br />occurs. <br />9 <br />
