• 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 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, Montrose County Weed Control Authority and the Division will <br />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. <br />9. Monitoring Reclamation Success <br />Monitoring the reclamation on an ongoing basis will assure successful reclamation. The operator <br />plans to use the local NRCS office to determine the capacity of the reclaimed land to control <br />erosion. If minor changes or modifications are needed to the seeding and reclamation plan, <br />revision plans will be submitted to the Division. It is hoped that the Division will provide <br />assistance in evaluating the success of the ongoing reclamation process. Information on all areas <br />disturbed and reclaimed ass well as any other important items regarding the reclamation will be <br />submitted in the annual reports to the Division. <br />10. Worst Case Reclamation Scenario <br />The worst case reclamation scenario takes place at the end of mining. At the worst case there <br />will be side slopes of 3H:1 V and flat pit floor which will need to be reclaimed. All areas will <br />receive an 8-12 inch layer of soil. The soil to be replaced will come from the two soil piles. <br />The only structure on site will be the truck scale. This will have a concrete foundation that will <br />need to be removed during reclamation. <br />• <br />Pinion Ridge Pit, June 2008 D-5
