RECLAMATION PLAN ADDENDUM EXHIBIT D 6.3.4 - Final grading will be such that the topography is appropriate to the reclaimed use of the property, i.e., as recreation. Any slopes created will be graded 2h to lv more or less. The floor of the mine will have a gentle slope to the northeast so drainage is consistent with existing grades on the site. The Reclamation Plan Map -Exhibit E-2 shows how we think the area will look when it is reclaimed. Once mining is complete the area will be shaped, graded and resoiled using the stockpiled growth medium to placed 3 to 6 inches over the disturbed area. When this is complete a mixture of grass seed (35#/ac), a fertilizer mix of 18~ Nitrogen and 46~ Potassium (250#/ac), fibermulch (400#/ac) and water (1450 #/ac) will be used to seed the prepared seedbed. Seeding will occur in the fall (after October 1st) or the spring after the last freeze but before May lat. The seed will be hydromulched per the USFS requirements. The seed mix required by the landowners is listed below. It was prepared by the Forest Service for the mine site and Grand County is required to use it. We also expect to see a natural invasion of fortis and woody plants from surrounding areas. No trees or shrubs will be planted on the mine area. Revegetation will be carried out in such a way, so as to establish a diverse, effective and long- lasting vegetative cover that is capable of self-regeneration without continued dependence on irrigation, soil amendments or fertilizers. The plan is to create a vegetative cover that is at least equal in extent to the cover of the natural vegetation before mining. The landowner will be asked to avoid disturbing off the site during three years to insure the seed takes. After the second growing season the site will be inspected and an assessment of revegetation success will be done to determine if additional seeding will be necessary. If the analysis shows additional work is needed it will done that fall. Weed control will be implemented prior to and during revegetation activities. This does not mean we will attempt to kill all weeds, since some provide a natural ground cover and shade for emerging grass. We will concentrate on controlling the noxious weeds on the reclaimed area, following normal NRCS recommendations if a problem occurs.
