. The Division and Mesa County weed control staff will be consulted regarding any weed <br />infestation azea 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 dry range site. <br />Weeds tend to provide shade for new gasses, 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 overburden, 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 azea will be monitored closely every yeaz which the permit is active to <br />determine if there aze any additional weeds invading the azea. Weed control will again be <br />initiated if the problem becomes serious. The Division will be consulted regazding any additional <br />weed infestation azea and any control measures prior to their initiation. If infestations of similaz <br />weeds as aze present now is experienced, the current weed control plan will continue to be used. <br />If any new species of weeds aze found, Mesa County Weed Control Authority and the Division <br />. will be consulted in order to formulate the best plan for the new infestation.

Revegetation Success Criteria <br />Since the pre-mine site is basically dry rangeland of relatively poor cover and production, and <br />the post-mining uses of the site are lakes and wetlands. The lakes do not require strict vegetation <br />success criteria. It is suggested that the dryland vegetation be approximately 10% perennial <br />cover. Since the Fruita area receives less than 10 inches of rain annually, no more than this wver <br />can be expected. <br />The wetland areas should be restored to typical wetland covers of at least 50% live perennial <br />• cover. The revegetated area will be monitored for success of reclamation until accepted by the <br />I S Road Pit February 07 E-7 <br />
