• Noxious Weed Control Plan This weed control plan is concerned with the control of all varieties of noxious weeds on the mine site. It was developed in coordination with Webb Callicutt, Coordinator, Delta County Noxious Weed Program (872-2110). Noxious weeds of concern in the general location of the Blue Ribbon Mine permit area are; 1) Russian knapweed, Musk, Canadian and Scotch thistle, Houndstounge, Oxeye Daisy, Burdock and Yellow toadflax. Yellow toadflax can be spayed anytime it is discovered. Spay with Banvel, 1.5 oz/gal. All of the other noxious weeds will be sprayed with Curtail, 2.0 oz/gallon mixed with a non- ionic surfactant at 1 quart per 100 gallons of spray. It will not be applied when spray particles may be carried by air currents to areas where desirable plants are growing. Spraying should~be performed when temperatures-are-under 80° F.- Spraying-will be done by use of a backpack spray system or an ATV mounted spray tank. Redeem mixed at 1.5 oz/gallon is also an acceptable herbicide. Oxeye Daisy can be spayed in the spring in the early flower stage. Houndstounge should be spayed in the spring in the early flower stage. Musk, Canadian and Scotch thistle should be spayed in the spring during late bud to early • flower. Russian knapweed should be sprayed in the spring and fall. Fall treatment is also appropriate for thistle rosetts and Canadian thistle. Burdock can be sprayed anytime. Mechanical removal is effective. The Operator commits to performing aggressive weed control during the operations and reclamation phases of the operation. Persons who perform weed control on BLM or USFS managed lands will be licensed. Exhibit AA shows the location where spot spaying has been performed and also shows areas of thistle infestation which cover over 100 square feet. Treated areas over 100 square feet in area will be examined each fall to determine if reseeding is appropriate. mR-~~ 113iv Revised 02/28/06 APPRoV~ 3~ry~o6
