~ ~ ~ <br />y. f ' i . 6/20/72 <br />,:OOLEY GRAVEL COMPANY ~ III IIIIIIIIIIIIIIII <br />MORRISON QUARRY 999 <br />MINING PLAN <br />The surface disturbances when completed will leave cuts approx. <br />8500' long and 700' deep. These cuts will commence at an elevation <br />of 6405' and extend to 7105'. The sides or faces of quarry <br />excavation when completed will be benched at a maximum of 80' <br />intervals and each bench will have a setback of at least one-half <br />the height of a single bench. All reasonable precautions will be <br />made to free the faces from loose material that might be <br />dangerous to employees. The slope of the faces will be determined <br />from the nature of the material being excavated, but in no case <br />will any slope exceed 80 degrees. Enclosed is a map showing <br />location and extent of the excavation now being proposed and a <br />recent aerial photo of the area, We have a scale model of the <br />area as it was-bore operations started and another identical <br />model with the removable sections to show the mining process from <br />start to finish, -- <br />Mining methods now being applied are drilling, blasting and dozing <br />the material to an accessible point for the handling with loaders, <br />The environmental resources which will be affected by the surface <br />disturbances are as follows: <br />1, Vegetation growth, scenics of and grazing in the area <br />of excavations for the quarry, roads and plant site. <br />2, Stream flow, drainage control and possibly water <br />quality of Strains Gulch. <br />Other resources that could be affected are as follows: <br />1. Hiking and associated recreational activities. <br />2. Wildlife <br />3, Heavy rainfall in the Strains Gulch watershed could <br />cause erosion of the fill area around the plant area and <br />stockpiles that might be deposited on pasture land below <br />or on Colo. Highway No. 8. Strains Gulch's channel <br />could become plugged. <br />4. Fugitive and operational dust deposited on surrounding <br />property, <br />5. Shock waves from blasting could result in damage to other <br />property, <br />The Thorne Ecological Institute has been retained to conduct an <br />Ecological Impact Study and Rehabilitation Plan for the areas <br />affected by the surface disturbances, Enclosed is a copy of a <br />proposal from them on this work. Recommendations are expected <br />
