<br /> <br />EXHIBIT "C" <br />PRE-MINING AND MINING PLAN MAP OF AFFECTED AREA <br />SPRING CREEK PASS <br />The total area of the proposed 112 pit is 35.00 acres. Excavation will continue from the <br />existing 111 permit site to the southwest. The southerly pit limits will be an existing fence. The <br />existing 111 site covers less than 10 acres and is mined out. It is anticipated that the maximum <br />disturbed area will be no larger than 13 acres during the estimated 30 year life. Amore detailed <br />description of the final configuration of the pit and contour map of the existing site can be found <br />in EXHIBIT "E & F". <br />There are no man-made structures or other land owners within 200 feet of the pit <br />boundary. <br />North Clear Creek is about a half mile to the northeast of the pit limits. There is an active <br />tributary to North Clear Creek passing through the northeasterly pit limits. Two 24" culverts are <br />in place where the access road crosses the tributary. The existing pit is dry and no discharge is <br />associated with this site or operation. CDOT has a Stormwater Discharge Permit from the <br />Colorado Department of Health, COR-320024. A copy of the Stormwater Management Plan can <br />be found in EXHIBIT "G". <br />Soils and vegetation information from the U. S. Department of Agriculture is attached to <br />this Exhibit "I & T'. <br />EXHIBIT "D" <br />MINING PLAN <br />SPRING CREEK PASS <br />It is anticipated that the material within the 35 acre pit limit will last 30 years. The <br />maximum disturbed site should not exceed about 13 acres. The site will be used intermittently for <br />production of crushed aggregates and hot mixed bituminous paving mix. A portion of the pit will <br />be used for stockpiling topsoil and crushed aggregates on a full time basis. <br />Removal of aggregates will be by traditional methods using dozers, loaders and trucks. <br />Topsoil will be removed and stockpiled prior to excavating a new area. Occasionally crushers and <br />hot plants will be used to process aggregates. The depth of useable aggregates in the existing pit <br />are about 15 feet. It is not anticipated to excavate deeper than 20 feet. Temporary cut slopes will <br />not be left vertical to insure slope stability and for safety of the public and livestock. <br />Material underlying the gravel layer is sand not suitable for road gravel and paving <br />aggregates. <br />
