EXHIBIT D <br />MINING PLAN <br />Rio Blanco County intends to pursue this proposed gravel pit as an aggregate source to <br />serve the needs of Rio Blanco County Road and Bridge, to be used in road maintenance. <br />Access to the site is off of Rio Blanco County Road No. 5, commonly known as Piceance <br />Creek Road. Rio Blanco County has leased the land and is intending to use an existing <br />upgraded access road that serviced the original gravel pit (Permit #M-2001-077) BLM <br />R.O.W. permit #COC-65417. <br />Mining operations (crushers, conveyors, dozers and scrapers) will be located in the <br />Northern portion of the gravel pit. The topsoil will be stripped and be placed in the form <br />of a berm along the perimeter of the project. This will accumulate over the life of the pit, <br />but will be re-vegetated within a 90-day time frame. Weeds will be controlled in all <br />disturbed areas and on the entire site. There is approximately 1 foot of topsoil and 4-6 <br />feet of overburden. The gravel will be mined generally from West to East. The mining <br />operations will be located in the Northern portion of the pit. All mining and processing <br />operation will be designed to manage storm water runoff, so that no sediments flow to <br />existing drainage. The storage of finished material will be stored along the Southerly <br />portion of the gravel pit on a slightly higher elevation to protect the finished product and <br />make it more available for transport. <br />The gravel bed lies under about 7 feet of soil. The gravel itself is approximately 16 feet <br />thick. There will be a maximum of 76,588 tons of gravel removed a year. Finished <br />products will be stockpiled on site. It is projected the life of this gravel pit to be fifteen <br />years. <br />Ground water is anticipated as this will be a wet pit. All groundwater and stormwater <br />runoff that accrues within the mining area will be piped into a nearby slough. <br />All exposed areas in the development will have topsoil replaced and seeded in <br />accordance with Soil Conservation Service recommendations. There will be temporary <br />haul roads down into the working area until such time that the portion of the excavation is <br />complete. <br />The floor of the gravel pit will be a constant grade running East to West of 1%, making <br />the Northwest portion of the pit the lowest point. <br />The estimated date that mining will commence is November 2008. Mining is estimated <br />to continue for approximately fifteen years. <br />The mining operation will use an existing access road off of Rio Blanco County Road <br />No. 5 that crosses private and BLM land, the road is permitted with the BLM as Permit <br />COC-65417.
