• <br />These vegetation patches that may be disturbed for quarrying will be <br />treated as follows. First the trees will be cut down. Then all the sparse topsoil <br />to bedrock will be saved and hauled to a stockpile on the permit. The <br />stockpiled topsoil will be small, but the stockpiled topsoil will be seeded with <br />native grasses to minimize erosion and blowing dust. Seeding will be in the <br />fall to maximize the opportunity for the seeding to prosper in the spring with <br />the snow water run off. <br />After completion of quarrying, equal areas of "vegetation patches" will be <br />established on the disturbed area, but not necessarily in the same original <br />locations. During quarrying, benches will be ]eft in place to approximate the <br />size of each disturbed vegetation patch. These benches and patches will be <br />somewhat randomly spaced to simulate existing conditions. They will be <br />connected to the permanent access road such that wildlife can access these <br />areas. Topsoil from the topsoil stockpile will then be replaced, and <br />Englemann spruce in at least like numbers to those destroyed will be planted. <br />In addition, native grasses will be seeded in these "new patches" in an attempt <br />to restore to nearly as is practicable pre-disturbed conditions. The vegetation <br />patches will be periodically watered to assure sustainable revegetation. <br />The permanent access road will be lefr in place such that permanent access <br />to the top of the mountain can be retained for future non-mining purposes. <br />A. OVERBURDEN. Except for sparse topsoil, there is no overburden to be <br />removed prior to dolomite quarrying. <br />B. IZFCLAIMED SLOPF. GRADIENT. The gradient of the slope of the <br />quarried out areas will be exactly the same as the gradient before quarrying <br />(37-degree dip). However, the small "revegetation patch" benches will be <br />essentially horizontal. <br />C. REVEGETATION. <br />.L The thickness of the topsoil at each existing vegetation patch will be <br />documented when it is removed and stockpiled. It will then be replaced <br />in like thickness during revegetation operations. Topsoil appears to be <br />less than l5 inches thick as it exists now-it is very thin. See USDA Soil <br />Conservation report on Exhibit I . <br />2 The replacing of the topsoil on the "revegetation benches" will take place <br />as quarrying progresses since it will be less expensive to back-haul the <br />topsoil back up the mountain while quarrying operations are underway. <br />To prevent erosion, seeding of the replaced topsoil will be immediate <br />after placement. It is doubtful if any seed bed preparation will be <br />necessary, but if needed, the replaced topsoil will be tilled with a farm <br />3 <br />
