5. Weed Control <br />Measures will be employed for the control of any noxious weed species. The objective of this <br />weed management plan is to control undesirable plants on the Tri County Pit property. Plants <br />identified through the Colorado Noxious Weed Act (C.R.S. 35-5.5) and the Delta 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 control measures. A <br />Weed Control Plan will be utilized as follows: <br />1) Each April, a weed survey will be taken of the permit area. <br />2) If any patches or plants have been identified, they will be sprayed by backpack sprayer or <br />4 -wheeler using chemicals approved for use by the weed control staff of Delta County. <br />3) After reclamation, weed surveys and spraying will continue until the perennial cover and <br />production of the site have met DRMS requirements and bond release has been obtained. <br />The Division and Delta County staff will be consulted regarding any weed infestation areas and <br />any control measures prior to their initiation. The plan does not contemplate total weed removal <br />on the property. Past experience has shown that some initial weed cover in the first year <br />following the retopsoiling is beneficial to the reclamation effort in rangeland site. Weeds tend to <br />provide shade for new grasses, are a means of holding snow on the seedbed longer and <br />protecting it from wind and water erosion until the planted species have taken hold. <br />During all phases of the mining operation the permit area will be monitored closely every year, <br />through which the operator may determine if any additional weeds have grown. If any new <br />species of weeds are found, Delta County and the Division will be consulted in order to <br />formulate the best plan for the new infestation. <br />Tri County Pit Sept 2016 E-4 <br />
