67a Weed Management Plan New Elk Coal Company's weed management goal is to prevent weeds from becoming established and to prevent the spreading of noxious weeds that may exist. Noxious weeds will be controlled by the guidelines for the Management of Noxious Weeds on Coal Mine Permit Areas as well as follow the Colorado Weed Management Act (Act 35-5.1-115) in case species of concern update over time. Mine disturbed areas will be monitored for infestations of Noxious Weeds. Whenever practical, mechanical control will be the control of preference. More aggressive infestations have been effectively controlled with Roundup mixed @ 2.66 oz per gallon of water, applied directly on the plant. As this is a non -restricted pesticide/herbicide, Roundup will be the preferred method of chemical control for annual and biannual thistle infestations. Mechanical control of Canadian thistle, a perennial, generally is ineffective. Thus, Canadian thistle will be cotrolled by an application of either Milestone, Banvel (dicamba) or a combination of 0.5 qt. Banvel plus 1.0 qt. of 2,4-D where Banvel alone proves ineffective. NECC will use localized seeding with the appropriate seed mix to promote healthy vegetation coverage on treated areas. The following table provides a list of target noxious weeds and Dr. Beck's (CSU) recommended herbicide.
