4. Weed Control <br />Measures will be employed for control of any noxious weed species. A Weed Control Plan will be <br />utilized as follows: <br />1) Each June, 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 4- <br />wheeler using chemicals approved for use by the weed control staff of Gunnison 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 Gunnison County weed control staff will be consulted regarding any weed infestation <br />area and any control measures before they are instigated. The plan does not contemplate total weed <br />removal on the property. Past experience shows that some initial weed cover in the first year following <br />the revegetation of an area can be beneficial. Weeds tend to provide shade for new growth, are a means <br />of holding snow on the seedbed longer and protect it from wind and water erosion until the planted <br />species have taken hold. <br />During the removal of overburden, if an area of heavy seed infestation is encountered, it will be buried <br />in the slopes rather than used as a growth medium. During all phases of the mining operation, the area <br />will be monitored closely every year in which the permit is active to determine if there are any <br />additional weeds invading it. Weed control will again be initiated if the problem becomes serious. The <br />Division will be consulted regarding any additional weed infestation area and any control measures <br />before they are instigated. If infestations of similar weeds to those that are present now are experienced, <br />the current weed control plan will continue to be used. If any new species of weeds are found, Gunnison <br />County Weed Control Authority and the Division will be consulted in order to formulate the best plan <br />for the new infestation. <br />Yule Quarry April 2012 47 <br />
