RECEIVED <br /> CASH AND WHO DO MINES 2 2018 <br /> WEED CONTROL PLAN <br /> DIVISION OF RECLAMATION, <br /> MINING AND SAFETY <br /> I. Introduction <br /> The existing land uses are forestry and mineral processing. The permitted property consists of <br /> patented and unpatented mining claims. All of the patented and unpatented claims are owned by <br /> the Colorado Milling Company, LLC (CMC). The other land in this area belongs to the U.S. <br /> Bureau of Land Management (BLM). <br /> II. State-listed Noxious Weeds <br /> There are several state-listed noxious weeds present onsite, including knapweed, Canada thistle, <br /> Common mullein, and Downy brome (cheat grass). <br /> III. Weed Control Plan <br /> CMC will perform a noxious weed site survey by the end of June each year. This annual site <br /> survey will be conducted until the site is released from reclamation liability by the Division of <br /> Reclamation, Mining, and Safety (DRMS). Any infestations of noxious weeds that are identified <br /> in this survey will be noted on the site map. A list of the weeds identified, the weeds sprayed, <br /> chemicals used, application rates, dates chemicals were applied, and the dates when the noxious <br /> weeds were effectively controlled will be filed with the DRMS prior to the end of each year. <br /> CMC will utilize the following mechanical and chemical methods to control noxious weeds: <br /> Field Trimming <br /> Prior to noxious weeds reaching full maturity (producing flowers/going to seed), the weeds <br /> will be mechanically mowed to a height of 2 to 4 inches. This trimming will be performed <br /> during the growing season in the late spring and late summer. Additional field mowing will <br /> be performed as necessary. <br /> Chemical Control <br /> One initial application of an appropriate selective herbicide shall be applied, per <br /> manufacturer's recommendations. Applications shall be done during the growth stage and <br /> when temperatures and other conditions are appropriate to achieve the most effective weed <br /> control. Follow-up applications will be done as needed. <br /> A list of the noxious weeds targeted for control within the State of Colorado that have been <br /> identified in this area is shown below: <br /> Common Name Scientific Name <br /> Canada thistle Cirsium arvenae <br /> Common mullein Verbaseum thapsus <br /> Downy brome Bromus tectorum <br /> Spotted/Diffuse knapweed Centaurea marulosa <br /> 1 <br />
