I ~ 4) A small irrigation ditch will be installed as shown on Map F. This ditch will be started at the <br />upstream portion of the East Drainage, and will be approximately 1.0 feet with sideslopes of 2H:1 V. <br /> <br /> <br />The grade will be less than 2% and the ditch will not be lined. <br />5) 13.5 acres of irrigated hay will be prepazed and seeded. <br />The dryland portions of the site will be seeded and mulched according to the recommendations of the <br />local NRCS. See report in Appendix C. The costs for the worst case reclamation scenario are given <br />in Exhibit L. <br />The seed mix to restore the dry rangeland azeas is given below: <br />Species Variety PLS/Acre <br />Western Wheatgrass Arriba 4.8 <br />Galleta Grass 0.8 <br />Indian Ricegrass Paloma 2.4 <br />Muttongrass or Sandberg bluegrass 0.1 <br />Bottlebrush Squirreltail 0.9 <br />Wyoming Big Sagebrush 1.0 <br />4 Wing Saltbrush 0.2 <br />Total PLS per Acre 10.2 <br />The rates above are for broadcast seeding, which will be the method employed on ail slope azeas. <br />The relatively flat areas (<8H:1 V) will be drill seeded. Certified weed-free mulch will be applied at <br />the rate of 30001bs per acre, and will be crimped into the soil surface. Commercial starter fertilizer <br />will be applied at the rate of 20 pounds available nitrogen. Before seeding and mulching, dead pinon <br />and juniper timber saved from the western portion of the mine azea will be relocated on the slope to <br />provide for erosion control, moisture trapping and shelter for young plants. This will be done at the <br />rate of 25 trees per acre. In addition, 75 total tubules of juniper and pinon (6" to 12" high} will be <br />BellgardtPit 1/06 <br />24 <br />
