CC&V: 2015 Weed Management Report <br />Spot applications of herbicides were used to control the six identified noxious weed species listed <br />in Table 1: Noxious Weed Species Treated During 2015. These applications were made along road <br />corridors, reclaimed rangeland, topsoil stockpiles, and areas of disturbance inside the mine permit <br />boundary. Application records were kept for all treatments implemented and are included in <br />Attachment A: Herbicide Application Records. All herbicide labels and Safety Data Sheets are <br />kept available by Habitat Management during herbicide treatments and can be provided upon <br />request. The primary herbicide mixture used on-site is outlined in Table 2. <br />Table 2: Primary Herbicide Mixture <br />Herbicide Name <br />Active Ingrediant <br />Application <br />Rate <br />Weedestroy AM40 <br />2, 4-D Amine <br />32oz/acre <br />Telar XP <br />Chlorsulfuron <br />1-1.5oz/acre <br />Induce <br />N/A <br />16-20oz/acre <br />Hi- Light Blue Dye <br />N/A <br />16oz/acre <br />Total Number of Acres Treated <br />9.5 acres <br />DISCUSSION OF TREATMENT AREAS <br />Habitat Management reviewed Cripple and Victor Gold Mine's Integrated Noxious Weed <br />Management Plan (2015). The primary goals of weed management at Cripple Creek and Victor <br />Gold Mine are to: (1) control noxious weeds within reclaimed portions of the permit area visual to <br />the public (2) control noxious weeds within the undisturbed portions of the permit in accordance <br />with state and Teller county requirements, and (3) minimize the potential for noxious weeds to <br />spread to adjacent properties and public lands. The focus of this fall treatment session was to locate <br />and treat Class "B" and Class "C" noxious weed species as designated by the state of Colorado. <br />Herbicide applications were scheduled to treat perennial noxious weed species that are actively <br />transporting carbohydrates to their roots, so that translocation of herbicides took place and <br />produced an effective kill against the targeted species. Biennial species that have already flowered <br />were ignored and treatments were focused on the rosette stage of both perennial and biennial <br />species. <br />Chemical control of noxious weeds was chosen as the most effective way to manage infestations. <br />Spot -applications were primarily used on targeted weeds, thereby minimizing herbicide impacts <br />on nearby native vegetation that in turn provides competition for noxious weed species. Only <br />herbaceous noxious weed infestations were treated at Cripple Creek and Victor gold mine during <br />the 2015 applications. The treatment areas located within the mine permit boundary are discussed <br />in detail below. <br />PHASE 5 <br />Treatment in the Phase 5 area was performed on September 28-29 and included all areas around <br />the facilities and pipelines on the top of the hill. The treatment area also included from the top to <br />the bottom of the slope and along the utility road leading up from the electrical facilities. The <br />eastern boundary of the treatment area was to the old highway and to the west was to the tailings <br />piles and to the edge of the reclaimed area. The area described was heavily infested with Dalmatian <br />toadflax and common mullein being the primary targeted species. Minor infestations of Canada <br />thistle, musk thistle and yellow toadflax were also treated. The treatment area was mainly infested <br />Habitat Management, Inc. 2 December 8, 2015 <br />
