4-73 <br />• 4.5.14 NOXIOUS WEED CONTROL PLAN <br />As identified earlier in this Section, one listed noxious weed in the permit <br />was identified during the base line vegetation survey, white top, Cardaria <br />Draba. At the time of this writing, 2006, both White Top and Canada <br />Thistle have been identified in the disturbed area. At the request of the <br />Division, the Operator's efforts are being formalized with the following <br />weed control plan. <br />This weed control plan is concerned with the control of all varieties of <br />noxious weeds on the mine site. It was developed based on <br />recommendations by Steve Anthony of Garfield County. <br />Canada Thistle will be sprayed with Curtail, 2 quarts/acre mixed with a <br />non-ionic surfactant at 1 quart per 100 gallons of spray. It will not be <br />applied when spray particles may be carried by air currents to areas <br />where desirable plants are growing. Spraying will be done by use of a <br />backpack spray system or an ATV mounted spray tank. <br />Canada Thistle should be sprayed in the spring, prior to bud stage. <br />Whitetop will be sprayed with 1-2 oz/acre Dupont Escort mixed with anon- <br />.` ionic surfactant at 1 quart per 100 gallons. It will not be applied when <br />spray particles may be carried by air currents to areas where desirable <br />plants are growing. Spraying will be done by use of a backpack spray <br />system or an ATV mounted spray tank. <br />Whitetop should be treated in the Spring between mid-April and mid-May <br />in the pre-flower stage <br />The operator commits to performing aggressive weed control during the <br />operations and reclamation phases of the operation. <br />At time of this writing, a heavy cover of downy brome (cheatgrass) has <br />become established on the topsoil stockpile. The stockpile will be <br />periodically treated with roundup to suppress growth of the cheatgrass. <br />~~ <br />McClave Volume 1 03/06 <br />
