C-21 <br /> Interim product stockpiles will be consumed during the life-of-mine operation as they constitute mid-stream process <br /> materials. To the extent any interim(or final)product may remain at the conclusion of all processing activities,the <br /> material will be either sold or donated,or utilized as clean backfill in site reclamation activities. <br /> Inasmuch as there are no rock outcrops or other exposures at the site, "waste rock" will be neither generated nor <br /> disposed as a component of the Keenesburg Project. <br /> (g) EXISTING/PROPOSED ROADS AND ASSOCIATED DRAINAGE FEATURES <br /> Existing and proposed roads are discussed in detail within subsection(e)Major Components of Mining Operation, <br /> above, and are depicted in Exhibit A-3: Permit Area and Proximal Features and Exhibit E-1: Mine Plan, <br /> respectively. These roads are limited to the existing ranch service road which will provide ingress and egress to the <br /> Permit Area(to be maintained in its current configuration);the to-be-constructed loadout loop road(wholly within <br /> the Permit Area);and,certain indeterminate and to-be-defined travel-ways which will be developed within the plant <br /> and pit operational area(s). The latter areas (travel-ways) are not anticipated to be "roads" per se, but rather <br /> operational surface areas upon which heavy equipment will operate. <br /> As described in Exhibit B: Site Description,regional drainage generally trends downward to the northeast. More <br /> localized drainage at and within the Permit Area varies, dependent on location within the prescribed boundaries of <br /> the Permit Area. Notably, the immediate area is comprised of surficial deposits of eolian sands,thus,there is high <br /> infiltration and limited runoff potential. In general,CSC has designed the Keenesburg Project to take advantage of <br /> these site-specific characteristics;and,due to the limited area of influence associated with the Permit Area location, <br /> no specific run-on or run-off potential is anticipated. Thus,no specific drainage features are warranted for the short- <br /> duration project. With the exception of mined-out depressions,natural drainage patterns will be restored at time of <br /> closure and site reclamation, as further detailed in Exhibit D: Reclamation Plan. <br /> The planned operations are to be situated at and around a localized high elevation area present in the southeast <br /> portion of the Permit Area. Potential up gradient run-on from the area of concentration to the west is diverted and/or <br /> limited by the presence of Weld County Road 59, which extends south to north at this location, in addition to the <br /> presence of the existing ranch service road. Potential run-on from the area of concentration to the south is naturally <br /> Keenesburg Project—Limited Impact 110 Application_May 24,2019 <br />
