6. Post-Reclamation Site Drainage <br /> Map C-2 and F-1 show drainage arrows which indicate the direction of surface water drainage <br /> throughout the site during and after mining. In general, the site will drain internally to the <br /> groundwater pond. <br /> 7. Revegetation Success Criteria <br /> Revegetation will be deemed adequate when erosion is controlled, the vegetation cover matches <br /> neighboring rangeland areas, and when it is considered satisfactory according to Division <br /> standards. This will be monitored in the two years following the completion of reclamation. <br /> 8. Weed Control <br /> This weed control plan is unchanged from the existing DRMS permit: <br /> United Companies will take measures to ensure that the land affected by the mining operation is <br /> free of weed infestations. Currently there are several problematic weeds which are present within <br /> the general area where the permit will apply identified by Delta County Weed Control. The two <br /> species are Russian knapweed and whitetop. Any infestations of these weeds will be removed prior <br /> to mining and will be monitored after reclamation has occurred. <br /> During all phases of the mining operation the permit area will be monitored closely every year which <br /> the permit is active to determine if there are any additional weeds invading the area. Weed control <br /> will again be initiated if the problem becomes serious. The Division will be consulted regarding any <br /> additional weed infestation area and any control measures prior to their initiation. If infestations of <br /> similar weeds as are present now is experienced the current weed control plan will continue to be <br /> used If any new species of weeds are found Delta County Weed Control. Authority and the Division <br /> will be consulted in order to formulate the best plan for the new Infestation. The plan does not <br /> contemplate total weed removal on the property. Past experience shows that some initial weed <br /> cover in the first year following topsoiling is beneficial to the reclamation effort. Weeds tend to <br /> provide shade for new grasses are a means of holding snow on the seedbed longer and protect it <br /> from wind and water erosion until the planted species have taken hold. <br /> 9. Monitoring Reclamation Success <br /> Monitoring reclamation on an ongoing basis will allow minor revisions to assure efficient and <br /> successful reclamation. The operator plans to use the local NRCS office to assist in determining <br /> the ability of the reclaimed land to control erosion. If minor changes or modifications are needed to <br /> the seeding and reclamation plan, revision plans will be submitted to the Division as required. It is <br /> hoped that the Division will provide assistance in evaluating the success of ongoing reclamation <br /> process. All areas disturbed and reclaimed and any other important items regarding reclamation will <br /> be submitted in the annual reports to the Division. Delta County and the Division of Parks and <br /> Wildlife will also be consulted on the progress of the reclamation. <br /> Anderson Pit <br /> September 2023 E'4 Lewicki&Associates <br />
