the hy~~ulcher, but areas available will be mulched. Figure 5-2 illustrates status <br />~. <br />of di:•,w ued and reclaimed areas. <br />5.3.4 Reclamation Fencing <br />All topsoil embankments, former laydown areas and seeded monitoring wells at <br />IRI-1 and EX-2 site have been fenced to exclude livestock grazing. <br />5.3.5 Monitoring <br />Per NaTec monitoring plan, preliminary (first two years) reclamation results will be <br />visually inspected and sampled by herbaceous evaluation. Past experience of <br />reclamation in th! Piceance Basin indicates approximately three years for seeded <br />species to become established without supplemental watering. Therefore, first <br />year results are very preliminary. <br />Topsoil embankments were inspected early in September, 1991 at the end of the <br />growing season. Perennial species were immature and grass species not <br />identifiable. Plant vigor and condition of seeded species was good. Erosion was <br />minimal or absent. Production of 200-400 Ibs/acre was excellent for first year <br />growth. Some heavy grazing was indicated, but fences were installed and gates <br />closed to eliminate grazing by wild horses during growing season. Weed species <br />were minimal at water and injection well sites but more evident at topsoil site near <br />evaporation ponds. An inspection by Colorado Mined Land Reclamation staff <br />' member of July 2, 1991 concluded that seedings from fall of 1990 had <br />"germinated, and barring any drought conditions, should provide a good cover on <br />the stockpiles". <br />39 <br />__ -. <br />
