EXHIBIT D <br />MINING PLAN <br />Rio Blanco County Road and Bridge intend to pursue this proposed gravel pit as a <br />periodic aggregate source for projects in the Rangely azea. <br />Access to the site is from that point adjoining Rio Blanco County Road No. 27. this is a <br />50 foot set-back from the road to help buffer any dust, noise and visual concerns. <br />Mining will commence in the Southeastern section of the pit. The mining will progress <br />Northwesterly. The topsoil and overburden will be stripped and stockpiled in the <br />Southwest azea of the mine site. These stockpiles will accumulate over afive-year <br />period, but will be re-vegetated within a 90 day time frame. All mining operations <br />(crushers, conveyors, dozers, and scrapers) will initially be stationed in the <br />aforementioned Southeast azea. All mining and processing operation will be designed to <br />manage storm water runoff, so that no sediments flow to existing drainage. <br />The gravel bed lies under about 3 feet of overburden and 6 inches of topsoil. The gravel <br />itself is approximately 15 feet thick. there will be a maximum of 20,000 tons of gravel <br />removed a year. Finished products will be stockpiled on site. <br />A. The estimated date that the mining will commence is July 2004. Mining is <br />estimated to continue for approximately 10 yeazs. <br />B. The estimated depth of topsoil is 6 inches (see EXHIBIT C -map, for stockpile <br />location) <br />C. The estimated depth of overburden is 3 feet (see EXHIBIT C -map, for stockpile <br />location) <br />D. The thickness of gravel deposit to be mined is approximately 15 feet. <br />E. The mining operation facilities will be located in the South area of the site (see <br />EXHIBIT C- map, for the operations location) <br />F. The disturbance azea and stockpiles aze shown on EXHIBIT C. <br />G. The nrining operation will use County Road No. 27 with no anticipated new <br />construction to such road. <br />H. Daily consumption is estimated at 1500 gallons of water or approximately''/z load <br />of water in a typical water truck. water will be delivered to the site in a Rio <br />Blanco County water truck. <br />I. During both mining and reclamation no impact on ground water is anticipated. <br />The mining operation will be conducted in such a manner as to maintain the <br />
