following table with associated disturbed area. The table illustrates a point in time where the <br />mining disturbance could be at its maximum. At the proposed Connell Carr Pit site, it is <br />assumed that the mining disturbance will be at its greatest midway through Phase I. During this <br />scenario, no reclamation will have been performed on the active mining face, approximately <br />500 feet of side slope on both sides of the mining face, and about half of the exposed pit bottom. <br />Since backfilling side slopes and the active mining face to a minimum 3H:1 V slopes is more <br />costly than "cut and fill" sloping, backfilling will be used to estimate reclamation costs (see <br />Exhibit L). <br />Mine Operation Aspects and Disturbance Areas <br />Diversions and Impoundments <br />The existing grade of the proposed permit area generally drains to the existing Lone Tree Creek <br />drainage. Stormwater that falls directly on disturbed areas will be generally drain to the mine pit <br />and allowed to infiltrate. The active mine pit will effectively contain stormwater flows and <br />prevent surface runoff from disturbed areas of the site. Stormwater not encountering disturbed <br />areas will be allowed to drain to Lone Tree Creek. <br />Material Processing and Associated Facilities <br />A portable processing facility for product crushing and screening will be brought to the site and <br />used as needed. The facility will be located within the pit close to where active mining is <br />occurring. A fueling/lubricating station, generators, and outdoor storage may also be located <br />near the portable processing facility. Pit run material will be hauled or conveyed to the <br />Connell Carr Pit <br />DBMS 112 Permit.
