(Page 21 MINE ID f OR PROSPECTING ID / M-94-022 INSPfiCTION 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 eandatone outcrop. The sandstone is a cliff former, and the cliffs and talus elopes extend high above the azea to be mined. The material to be mined initially ie a colluvium derived from the sandstone, and contains many sandstone blocks. Fractured eandatone bedrock will probably be encountered at acme depth into Che knob, the operator will bleat ae necessary to excavate the material. There ie a good cover of grasses and shrubs on the level area on top o£ Che knob, and Fair vegetative cover on the elopes. 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 raining wlll 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: Sceciea 8luebunch wheatgraea Western wheatgraea Greeted wheatgraea Indies Ricegraes lbs. of Pure Live seed cer 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 ba mined and the county road_ Also, the road Se not appreciably built up above the surrounding ground surface, so will not effectively serve ae 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 aide of the road to route run-ofE from the disturbed area to the sediment control structures described in the application (alternatively, the road could be built up eo that it would serve ae a dike, as indicated in the application). All final elopes developed in soil or uncronaolidated 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 moat be stable. All level areas and graded elopes must be revegetated. The Division will provide a conditional approval letter, with a list of at ipulat ions, under eegarate cover. OPERATIONS HAY NOT COHMENCE VNTIL THE PERMIT IS ISSVED.
