CC&V: 2016 Weed Management Report and specific information on the various species treated and their location is provided to Cripple Creek and Victor Gold Mining Company in shapefile format. Spot spraying applications were used to control the eight identified noxious weed species listed in Table 1. These applications were made along road corridors, reclaimed rangeland, topsoil stockpiles, trail systems, and areas of disturbance inside and outside the mine permit boundary. Application records were kept for all treatments implemented and are included in Attachment A. All herbicide labels and Safety Data Sheets are kept available by Habitat Management during herbicide treatments and can be provided upon request. The primary herbicides used on-site is outlined in Table 2 and Table 3.

The primary goals of weed management were to: (1) control noxious weeds within reclaimed portions of the permit area visual to the public (2) control noxious weeds within the undisturbed portions of the permit in accordance with state and Teller county requirements, and (3) minimize the potential for noxious weeds to spread to adjacent properties and public lands. The focus of summer and early fall treatment sessions were to locate and treat List "A", List "B" and List "C" noxious weed species as designated by the state of Colorado. Herbicide applications were scheduled to treat annual, biannual, and perennial noxious weed species prior to plants setting seed, thus reducing the seed bank population. Later season applications targeted perennial noxious weeds that are actively transporting carbohydrates to their Habitat Management, Inc. 2 December 27, 2016
