RECEIVED <br />COLORADO MILLING COMPANY, LLC NOV 2 0 2017 <br />WEED CONTROL PLAN <br />Di1/1Si0N OF RECLAMATION, <br />I. Introduction MINING AND SAFETY <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 />l�I. 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 <br />Scientific Name <br />Canada thistle <br />Cirsium arvenae <br />Common mullein <br />Verbasewn thapsus <br />Downy brome <br />Bromus tectonrm <br />Spotted/Diffuse knapweed <br />Centaurea marulosa <br />
