C-22 rl <br /> Liquefied Natural Gas Storage <br /> Two portable 10,000 gallon liquefied natural gas(LNG)tanks,plus a portable vaporizer unit,will be located <br /> within an approximately 3,100 ft2 area alongside the right shoulder of the ranch service road. This location <br /> (interior to the Permit Area) is near the intersection of the ranch service road and the terminal end of the <br /> loadout loop road(e.g.,the southwest corner of the Permit Area). Protective barriers will be installed on all <br /> sides of the installation. The LNG installation (and other facilities, as appropriate) will comprise a <br /> component of the facility's Hazardous Materials and Emergency Response Plan. <br /> LNG will be delivered to site via a third-party contractor. <br /> (f) SIGNIFICANT DISTURBANCE FEATURES <br /> Significant disturbance features associated with the Keenesburg Project include: (1)the main mine pit,as described <br /> above in (E) (ii); and, (2) the fines recovery pit, as described above in (E) (iii), respectively. There will be no <br /> impoundments (other than the above-described fines recovery pit), no stockpiles (other than the above-described <br /> interim product stockpiles), and no waste rock disposal areas. <br /> The main mine pit will be roughly rectangular in shape (longitudinal axis oriented west to east), with a nominal <br /> length of 575 ft., width of 235 ft. and a projected depth limit ranging from 25 ft. to 30 ft., dependent on existing <br /> topography. While benching may be employed during the short-duration mining operation,pit design incorporates <br /> side-slopes consistent with the sand material's natural angle of repose(or 3H:1 V). <br /> The fines recovery pit will be a short rectangular-shaped area (in footprint), nominally 275 ft. in length (west to <br /> east) by 235 ft. in width (north to south). It will be excavated to a depth nominally equivalent to that of the main <br /> mine pit. Once excavated, the fines recovery pit will be continuously filled during the life-of-mine processing <br /> activities. <br />
