<br />will be use in slope backfilling and re-grading prior to topsoil replacement. The <br />temporary stockpiled overburden will be utilize in the yearly slope and pit reclamation <br />resulting in minimal overburden storage from year to year. <br />4. Thickness of Gravel to be Mined: The average thickness of gravel in the southern <br />expansion area is 13 feet with a range from 8 to 18 feet. <br />5. Components of the Mining Operation: Connell Resources, Inc. does not anticipate <br />any change from past levels of activity at the Camilletti Pit. Materials are hauled by <br />tandem and belly dump trucks via an access road from the pit to Routt County Road <br />51A. The truck scale is located on the access road. No road improvements, building <br />structures, or permanent fuel storage tanks are planned for this pit. Employees at the pit <br />include a scale person and loader operator during limited periods of operations, <br />commonly lam to 7 pm Monday through Friday when materials are needed for a <br />contract or nearby project. A crushing plant and crew will be brought into the pit, usually <br />once a year, if specification aggregates are needed for a nearby project. The crusher <br />would be located in the bottom of the pit. A small scale house is located along the <br />access road near the truck scale. Portable toilets are utilized during periods of <br />operation at the scale house and in the pit. As a complementary use, Connell <br />Resources, Inc. will occasionally recycle small amounts of asphalt and concrete to <br />blend with road base gravel. The maximum quantity expected is 5000 tons per year of <br />asphalt and 1000 tons per year of crushed concrete. <br />6. Dimensions of Disturbances: The Exhibit D map shows the phased mining of the <br />south pit wall. Each year's mining of the south wall should be approximately 900 feet in <br />length by 75 feet in depth. This should produce topsoil stockpiles of around 300 feet in <br />length, 25 feet width, and 6 feet in height. A significant portion of the topsoil stockpiles <br />will be utilized each year for slope reclamation. <br />The current pit is dry. The proposed southern expansion of the pit will also be dry. <br />Most of the drainage in the pit is internal. There have been no soil erosion or surface <br />water pollution problems in the past and no problems are anticipated with the southern <br />expansion. Exhibit D also contains a copy of the Storm Water Management Plan for the <br />Camilletti Pit. <br />5 <br />
