EXHIBIT C MINING PLAN Rio Blanco County Road and Bridge intend to pursue this proposed gravel pit as a periodic aggregate source for projects in the Rangely azea. Access to the site is from nearby Rio Blanco County Road No. 2 Mining will commence in the Northern section of the pit. The mining will progress Southerly. The topsoil and overburden will be stripped and stockpile in the Southern azea of the mine site. These stockpiles will accumulate over afive-year period, but will be re- vegetated within a 90 day time frame. All mining operations (crushers, conveyors, dozers and scrapers) will initially be stationed in the aforementioned Northern area. All mining and processing operation will be designed to manage storm water runoff, so that no sediments flow to existing drainage. The gravel bed lies under about 6 inches of topsoil. The gravel itself is approximately 20 feet thick. There will be a maximum of 20,000 tons of gravel removed a yeaz. Finished products will be stockpiled on site. A. The estimated date that mining will commence is July 2004. Mining is estimated to continue for approximately ten yeazs. B. The estimated depth of topsoil is 6 inches (see EXHIBIT E -map, for stockpile location) C. The estimated depth of overburden is 4 feet D. The thickness of the gravel deposit to be mined is approximately 20 feet. E. The mining operation facilities will be located in the Northern azea ofthe site (see EXHIBIT C -map, for the operations location) F. The disturbance azea and stockpiles are shown on EXHIBIT E G. The mining operation will use an old existing access road connecting to County Road No. 2. The access road will be improved to accommodate the mining operation. x. Daily consumption is estimated at 1500 gallons of water or approximately % load of water in a typical water truck. Water will be delivered to the site in a Rio Blanco County water truck.
