The site is historically windblown dunes and cattle grazeland . The site will be revegetated <br /> with an upland grass seed mix in areas that are above the highwater line. <br /> v. Topsoiling-specify anticipated minimum depth or range of depths for those areas <br /> where topsoil will be replaced. <br /> Topsoil will be uniformly placed and spread on all areas disturbed by the mining above the <br /> anticipated high water line and areas graded back to native grade. The minimum <br /> thickness shall be 12 inches above the surrounding finished grade. <br /> WEED MANAGEMENT PLAN <br /> Noxious weeds will be eradicated or managed within the Section 25 Sand & Gravel Mine <br /> operations areas. Noxious weed species to be managed are defined as those plant species <br /> currently identified by the Colorado State Department of Agriculture (CDA) as noxious under the <br /> Colorado Noxious Weed Act. Management efforts will be directed to those species identified under <br /> List A or List B by the CDA. List A species are required to be eradicated, while List B species will <br /> be controlled. <br /> The noxious species are not listed here as the list of noxious species changes regularly. The <br /> Colorado State Department of Agriculture maintains a list of noxious weed species on their web <br /> site (https://www.colorado.gov/pacific/agconservation/noxious-weed-species). <br /> The presence of noxious weeds will be monitored annually during the summer growing season at <br /> the Section 25 Sand & Gravel Mine site. Weed management measures will be undertaken where a <br /> single or combination of noxious weed species comprises or shows a deleterious effect to more <br /> than ten (10) percent of the live site vegetation. Further, where noxious weed species or plant <br /> pests constitute more than 25 percent relative vegetation cover in a contiguous area of 1000 <br /> square feet, the area will be identified as requiring weed management. <br /> Noxious weeds will be controlled by any combination of cultural, mechanical, biological or chemical <br /> measures. Weed control measures will be developed specifically for the noxious weed species <br /> encountered and in conjunction with the local county weed control district and/or the Colorado <br /> State Department of Agriculture. Weed control measures will be undertaken by trained and/or <br /> licensed (if required by law) personnel. Weed management control will initiate within two weeks of <br /> noxious weed identification at any operation, or as specified by the county weed control specialist. <br /> Where noxious weed control measures cause elimination of vegetation at a revegetated site, <br /> seeding or planting of desirable replacement vegetation will occur during the first normal planting or <br /> seeding season after weed control measures have been implemented. <br /> 70 Ranch-Section 25 Sand Mine—MLRB 112 Permit Application <br /> Exhibit E-6 <br />
