4.0 Site Description <br />4.10 <br />perations Structures <br />CM -25 is a designated mining operation. Uranium and vanadium minerals will be mined <br />underground producing ore that will be temporarily stored on the surface while awaiting <br />transport to a processing facility. Waste rock will also be stored on the surface. At the present <br />time, the site has been reclaimed, including vegetation that has become well established. There <br />are no operational structures presently located at the site. <br />Once mining resumes, the waste rock stockpile will be the major feature of the site, extending to <br />the east from the portal area. This man -made feature will provide a working area that may <br />contain the site office, water tanks, and a future ore stockpile area. When mining resumes, it is <br />anticipated that additional storage facilities for compressors, generators, maintenance equipment, <br />and supplies, plus a 500- gallon diesel fuel tank with secondary containment, will be installed at <br />the site to support mining activities. <br />Clay soils from nearby will be placed on the waste rock pile, compacted, and used as a <br />temporary storage area for ore mined at the site. As mining continues, the waste rock pile will <br />expand in an eastern direction. The area below the waste rock stockpile will contain the runoff <br />retention pond for the site. Some excavation and embankment will be required to create this <br />pond, proposed in the lowest topographic area of the site. <br />The existing entrance road that connects to nearby county road EE 22 will be used as a haul road <br />to periodically transport ore from the mine. <br />4.2 Surrounding Area Characteristics <br />Vegetation <br />Most of the affected area at CM -25 is classified as a Pinon- Juniper (P -J) Woodland range. A <br />small portion consists of steep rock outcrops that support little or no vegetation. According to the <br />P -J range site description, this plant association generally occurs between 5,000 and 7,500 feet. <br />Precipitation ranges from 12 -15 inches per year, with an average annual temperature between 49 <br />and 53 degrees F. <br />Secondary species associated with a P -J rangeland site include: <br />Indian ricegrass <br />Blue grama <br />Galleta <br />Cheatgrass <br />Fendler three awn <br />Rabbitbrush <br />Snakeweed <br />Fleabane <br />Mountain mahogany <br />Big sagebrush <br />Cliff rose <br />Sedges <br />ESWMP -2 <br />
