Vegetation Information <br />Exhibit J <br />The site has historically been used for growing grass hay and cattle grazing. The vegetation community on <br />the entire permit area is vegetated with a medium to dense vegetation and is considered irrigated pasture. <br />The predominant grasses on site are timothy and intermediate wheatgrass. Smooth brome and other <br />grasses are present in smaller percentages. White clover is also present. Historically, alfalfa has also been <br />grown in the field. The estimated live perennial cover during irrigation season is 50% to 75%. <br />Prior to leveling and irrigation, the field probably contained mainly basin wildrye, western wheatgrass, <br />streambank wheatgrass, bluegrasses, and big sagebrush. Smaller amounts of rubber rabbitbrush, fourwing <br />saltbush, and bottlebrush squirreltail aze also commonly present in similaz azeas that have not been <br />disturbed. <br />The hillsides to the south of the permit aze above the field consist of sparse pinyon, juniper, mountain <br />brush, sagebrush and some grasses. Soils on these slopes are thin compazed to those in the meadow. <br />All vegetation communities can be seen on Map C-1 Pre-Mining Plan Map. Westwater Consultants has <br />done a preliminary wetland evaluation of the site which is enclosed on the following pages. Since mining <br />will progress from the eastern side of the site, Area D, as mentioned in the Westwater report, will not be <br />affected for at least a yeaz after mining commences. During this period, irrigation water will be cut off <br />from Area D. A full wetland evaluation of the site will be conducted before the area could experience <br />drawdown from mining to the east. If portions of Area D aze still shown to be jurisdictional wetlands after <br />the removal of irrigation water supply, then an Individual Permit will be applied for with the US Army <br />Corps of Engineers to allow for its disturbance. The currently planned wetlands that will be built during <br />reclamation should satisfactorily replace any disturbed jurisdictional wetlands. <br />White River City Pit December 06 I-3 <br />
