concurrently with mining. This will reduce material moving as well as reduce the maximum area <br /> to be reclaimed; maximum disturbance is discussed in Exhibit L. <br /> Excess shale and surplus overburden will be permanently stored in a dump located east of the <br /> processing area designed with 3H:1 V slopes, see Maps C-2 and F-1. This dump will be utilized <br /> as excessive waste fines, overburden, and/or shale are encountered during mining. The dump will <br /> only be utilized if the waste material cannot immediately be placed into a mined-out phase. The <br /> dump will be constructed by edge dumping in lifts of approximately 25 feet in height creating an <br /> overall final slope of 3H:1 V. A typical cross-section detailing the construction and final <br /> reclamation geometries of the dump slope is detailed in Figure 4. A settling pond will be located <br /> at the base of the dump to handle stormwater runoff from only the dump slope area (Figure 5). <br /> The top surface of the dump will drain west towards the processing area sump. Final dump <br /> reclamation will only occur at the end of mining. Final reclaimed dump slopes will feature catch <br /> ditches to collect surface flows, minimize incision, and funnel flows into the dump slope sump. <br /> All water collected in the dump slope sump will penetrate the dry porous surface within 72 <br /> hours. <br /> Bradford Mesa Quarry X 1 ,, �.,..­ 1111.1-1 f9 aI <br /> January 2020 D-10 <br />
