3) After reclamation, weed surveys and spraying will continue until the perennial cover and production of the site meet DRMS requirements and bond release is obtained. The Division and Clear Creek County staff will be consulted regarding any weed infestation areas and any control measures prior to their initiation. The plan does not contemplate total weed removal on the property. Past experience shows some initial weed cover in the first year following retopsoiling is beneficial to reclamation efforts on rangeland sites. Weeds tend to provide shade for new grasses, are a means of holding snow on the seedbed longer, and protect seedlings from wind and water erosion until the planted species take hold. All phases and areas of the mining operation will be monitored closely throughout the year allowing the Operator to determine if any additional weeds become present. If any new species of weeds are found, Clear Creek County and the Division will be consulted to formulate the best plan to mitigate the new infestation. 6. Revegetation Success Criteria Areas will be deemed adequate when vegetation is established to control erosion and noxious weeds are not present in any significant amounts and all of the conditions of Rule 3.1.10 are met. 7. Monitoring Reclamation Success Monitoring reclamation on an ongoing basis will allow minor revisions to assure efficient and successful reclamation. The Operator plans to use the local NRCS office to assist in determining the ability of the reclaimed land to control erosion. If minor changes or modifications to the seeding and reclamation plan are needed, revision plans will be submitted to the Division, as required. It is hoped that the Division will provide assistance in evaluating the success of ongoing reclamation process. All areas disturbed and reclaimed and any other important items regarding reclamation will be submitted in the required annual reports to the Division. DMR - April 2018 E-4
