EXHIBIT D <br /> <br />Mining Plan <br /> <br />SHAVANO PIT <br />An existing pit on adjoining land o~•med by the Federal <br />Government was first opened to sand and gravel extraction <br />by the Uncompahgre 4Jater Users Association in the 1930's. <br />The operation has ~•~orked its way onto County owned land <br />durino the 1950's and ~•iill continue to be located on <br />County owned land. At the present time, the mining opera- <br />tion is progressing from 41est to East. Approximately <br />every 12-18 months, a gravel crushing and processing plant <br />is set up on the site. At that time, as much as 30,000 <br />yards are processed and stock piled for future use. In <br />completing this operation, topsoil is stockpiled and gravel <br />is transported to the crusher with 4 wheel drive front <br />end loaders. The gravel is stock piled on site in piles <br />up to 15' in height. l•Jhen the gravel is removed from the <br />site, front end loaders and trucks are used. <br />Because the topsoil on the site is minimal in several <br />places, not much topsoil has or will be stock piled. <br />The resulting floor of the pit is nearly level and will <br />remain so after mining has been completed. <br />The Shavano Pit does not show any signs of ground water and <br />there are no requirements for surface water diversion and/or <br />impoundment. There is less than 9.0" of rain/year in the <br />area and the site is the highest elevation in the vicinity. <br />The area mined to date (under County ownership) is approxi- <br />mately 5 acres. The surface area to be mined at any one time <br />is about .75 acres. Because of the location of this pit, <br />the County intends to extract gravel from the site as long <br />as a deposit remains. This is estimated to be about 20 years. <br />
