Fremont County Weed Control 6i5 Macon Avenue Conan City, Colorado 81212 October 3, 2006 Mr. William Tezak Colorado Quarries Inc. Canon City, Colorado 81212 RED Weed Management on Property Associated with Mica Lode Pit M-77-144 Dear Mr. Tezak, This letter is provided to report on observations regarding weed infestations for property you have permitted near the Royal Gorge area west of Canon City (Mica Lode Pit). The access road from the road leading to the Royal Gorge Bridge south of state highway 50 into the inactive mining area, roads and benches at the mine and related property is as you know infested with Spotted, Diffuse and Russian Knapweed. Per my review of the area and a tour on September 27, 2006, it is estimated that future control efforts should include herbicide spraying in selected areas. The local infestations will require spot spraying along the main roads, in adjacent disturbed areas and rangeland on areas of the permitted mine site. Herbicides have been shown to be effective in a multi-year program where mechanical, cultural and biological controls are also part of management. Timing of herbicide application in the next growing season coupled with a relaxed or limited use of graders or other equipment in the infested areas can also limit the spread of these important and potentially damaging weeds. In this case, n timetable should be established to control the infestation. Treatment should be initiated as soon as practical in the 2007-growing season. Continued regular management in succeeding years will be required to control the noxious weeds at a reduced expense and effort. Fremont County can provide the service and strategy to implement your weed management efforts. I will look forward to providing follow-up information and discuss a strategy in the near future ns you may request. lace ~e ~ ~ ~ -J:R. Phillips, Manager
