7. Weed Control <br /> Weeds are minimal in the pre-mine site. Measures will be employed for control of any noxious <br /> weed species. Control measures will also be used if growth of weed species on the reclaimed <br /> area threatens further spread of weeds to nearby areas. A Weed Control Plan will be utilized as <br /> follows: <br /> 1) Following seeding, a weed survey will be made of the permit area. <br /> 2) If any patches or plants have been identified,they will be sprayed by backpack sprayer or <br /> four-wheeler using chemicals approved for use by the weed control contractor for <br /> Saguache County. <br /> 3) After reclamation,weed surveys and spraying will continue until the perennial cover and <br /> production of the site have met DRMS requirements and bond release has been obtained. <br /> The Division and Saguache County weed control staff will be consulted regarding any weed <br /> infestation area and any control measures prior to their initiation. The plan does not contemplate <br /> total weed removal on the property. Past experience shows that some initial weed cover in the <br /> first year following the retopsoiling is beneficial to the reclamation effort in rangeland sites. <br /> Weeds tend to provide shade for new grasses, are a means of holding snow on the seedbed longer <br /> and protect it from wind and water erosion until the planted species have taken hold. <br /> During the removal of topsoil, if an area of heavy seed infestation is encountered, it will be <br /> buried in the slopes rather than used as a growth medium. During all phases of the mining <br /> operation,the permit area will be monitored closely every year which the operator is active to <br /> determine if there are any additional weeds invading the area. If infestations of similar weeds as <br /> are present now is experienced, the current weed control plan will continue to be used. If any <br /> new species of weeds are found, Saguache County 's weed control contractor and the Division <br /> will be consulted in order to formulate the best plan for the new infestation. <br /> 8. Revegetation Success Criteria <br /> Revegetation will be deemed adequate when erosion is controlled, and the vegetation is <br /> considered satisfactory according to Division standards. This will be roughly 30-40%cover. <br /> Hooper Pit D-3 <br /> April 2020 _X (;reg Lcwicki and Asaociattx,PI,IA' <br />
