(Page 2) MINE ID # OR PROSPECTING ID # M-94-022 INSPECTION DATE 5-12-94 INSPECTOR'S INITIALS ACS OBSERVATIONS This was a pre -operational inspection conducted primarily to verify the soils and vegetation information provided in the application, and to clarify the logistics of the mine plan. The material to be excavated is in an approximately 20 to 30 foot high topographic knob protruding from a sandstone outcrop. The sandstone is a cliff former, and the cliffs and talus elopes extend high above the area to be mined. The material to be mined initially is a colluvium derived from the sandstone, and contains many sandstone blocks. Fractured sandstone bedrock will probably be encountered at some depth into the knob, the operator will blast as necessary to excavate the material. There is a good cover of grasses and shrubs on the level area on top of the knob, and fair vegetative cover on the slopes. Species observed included Sage, Indian Rice Grass, and several wheat grasses (Bearded Bluebunch, Griffith's). The surface soils at this location are too rocky and thin to justify salvaging for reclamation, however, crusher fines and unconsolidated earth exposed in mining will provide a useful plant growth medium. The Division will require revegetation of the disturbed area (no revegetation'had been proposed by the applicant). The Division recommends the following seed mix: Species Bluebunch wheatgrass Western wheatgrass Crested wheatgrass Indian Ricegrass lbs. of Pure Live Seed per acre 5.0 2.9 2.0 1.0 These rates are for drill seeding and must be doubled if the seed is broadcast. Clean straw mulch is to be applied at a rate of 2 tons per acre and crimped into the soil or secured with netting. If the operator elects to use a different seed mix at the time of reclamation, the alternate mix must first be approved by the Division. At the start of the operation, there will be limited level ground available between the knob to be mined and the county road. Also, the road is not appreciably built up above the surrounding ground surface, so will not effectively serve as a dike between operations and Slater Creek. For these reasons, the operator will have to take care to avoid siltation or other disturbance of the creek. The Division will require that a ditch be excavated along the west side of the road to route run-off from the disturbed area to the sediment control structures described in the application (alternatively, the road could be built up so that it would serve as a dike, as indicated in the application). All final slopes developed in soil or unconsolidated material must be graded no steeper than 2H:1V. Slopes developed in competent bedrock may be steeper but should blend with the natural terrain, and must be stable. All level areas and graded slopes must be revegetated. The Division will provide a conditional approval letter, with a list of stipulations, under separate cover. OPERATIONS MAY NOT COMMENCE UNTIL THE PERMIT IS ISSUED.
