Ms. Camille Farrell Mined Land Reclamation December 27, 1985 Page 2 C. Topsoil stockpile grading and seeding. The applican will commit to grading topsoil stockpiles no steeper than 3H: V slopes and seeding with a perennial cover crop to preserve the ntegrity of the topsoil. Exhibit C - Map The operator agrees to stake the proposed 9.8 acre mine ~ite to insure the stages within permitted boundaries. Exhibit D - Wildlife, Water Resources, Vegetation, Soil~nformation 1. A. Will mining occur in the ephemeral drainage? Ex ibit B - Mining Plan, states "The proven clay lies roughly in 2 p rallel fingers separated by a small swail and running from northwest to southeast. There is no intent to mine in the swail or ephemeral dra Wage or to disturb it. The sparse vegetative growth will be left i tact. B. How will the channel and banks be reclaimed? As staged in A, there will be no effect on the channel or banks. C. How reclaimed channel will relate to the undisturbed channel upstream and/or downstream. No disturbance of the exist ng channel. D. How will headcutting and general channel erosion be ~inimized? The existing channel is vegetative and indicates no sign of erosion. Caprock stockpiles on the perimeter of the swail will pr vent any erosion into it. i Exhibit E - Reclamation 1. Approximate topsoil replacement depth. The SCS repot states in part: "The suitability of Travesilla for topsoil is rate poor due to the layer being thin." "Prior to mining, all topsoil which can be reasonably removed should be stockpiled. Since outcrops of sandstone occur throughou the proposed mining area, topsoil collection should be selective." It is anticipated that maximum topsoil for replacement over the affected area will be 3" to 5". 2. Slope gradient where the pit perimeter "feathers into' the adjacent outcropping. The flat pit floor will feather into adjac t topography with elopes of 3H: 1V on the east to 6H:1V on the west.
