The objective of this weed management plan is to control undesirable plants on the Alma Placer ' <br /> Mine property where measures will be employed for the control of any noxious weed species. <br /> Plants identified through the Colorado Noxious Weed Act(C.R.S. 35-5.5) and the Park County <br /> Noxious Weed List as undesirable and designated for management within the County will be <br /> removed. These plants identified as noxious weeds will be managed by standard control <br /> measures. A Weed Control Plan will be utilized as follows: <br /> 1) Each April a weed survey will be conducted for the entire permit area. <br /> 2) If any patches or plants are identified, a backpack sprayer or 4-wheeler with be used to <br /> apply chemicals approved for use by the weed control staff of Park County. <br /> 3) After reclamation,weed surveys and spraying will continue until the perennial cover and <br /> production of the site meets DRMS requirements and bond release is obtained. <br /> The Division and Park County staff will be consulted regarding any weed infestation areas and <br /> any control measures prior to initiation. The plan does not contemplate total weed removal on the <br /> property. Past experience shows that some initial weed cover in the first year following <br /> retopsoiling is beneficial to the reclamation effort in rangeland sites. Weeds tend to provide <br /> shade for new grasses, are a means of holding snow on the seedbed longer, and protect seedlings <br /> from wind and water erosion until the planted species are firmly established. <br /> Constantly throughout the year, during all phases and areas of the mining operation, the Operator <br /> may determine if any additional weeds are present. If any new species of weeds are found, Park <br /> County and the Division will be consulted in order to formulate the best plan for the new <br /> infestation. <br /> 6. Revegetation Success Criteria <br /> It is suggested that revegetation of the reclaimed area should be deemed successful when the <br /> perennial vegetation in this area is self-sustaining and adequate to control erosion. The topsoil <br /> replacement procedures and the revegetation plan outlined earlier should be more than adequate <br /> to achieve this goal. The majority of the site is reclaimed using standard procedures for restoring <br /> Alma Placer Mine Civu Iw..1.anti%-wW O"E1AX <br /> December 2017 E-6 <br />
