Flag Resources, Inc. <br />Silt Pit <br />M.L.R.B. Permit # M-1981-202SG <br />Revised 9/07/10 <br />Page 1 <br />Weed Control Plan <br />ORIGINAL: SEPT 2006 <br />This plan will be implemented as part of the normal opera- <br />tion of the mine. This weed plan covers all noxious weeds <br />identified by the SCS and Division but specifically addresses <br />Russian Knapweed, and hoary cress (white top) because it is our <br />prevalent problem. Tamarisk is also present on the site and a <br />control plan for it is included. We have been spraying yearly in <br />the spring to control the Russian Knapweed and will continue that <br />practice. We will now implement a fall inspection and spraying <br />regiment to the spring control efforts to better control weeds <br />around the mine. <br />We have found a moderate to light infestation of Russian <br />Knapweed and hoary cress along the roads and critical disturbance <br />areas. In other areas there is a scattering of Knapweed in the <br />reclaimed and undisturbed areas. We did not use any particular <br />scientific method to make the designations noted above, but did <br />use common sense when comparing the various areas to arrive at <br />the three descriptions listed below. Under each definition we <br />explain how we arrived at that classification and the typical <br />area where the problem occurs. <br />Moderate <br />These areas are typically on the edges of roads, around <br />active mining areas and near stockpile areas. The road <br />areas are all in this area but only the sides are infected <br />since traffic tends to inhibit growth on the road surface. <br />The weeds needing control appear to grow best along the <br />perimeters where the seeds accumulate on newly disturbed <br />area. In addition, old overburden piles that have some <br />vegetative cover and other areas include recent topsoil <br />piles that have not been disturbed for a growing season. <br />Light <br />This area covers the majority of the site. It has product <br />piles on it, is graded for storage or processing areas and <br />is being disturbed regularly. Because the area is disturbed <br />regularly, the problem weeds have a hard time getting a foot <br />hold. Little or no vegetation exists on these areas because <br />of the active mining and stockpiling takes place year <br />around. <br />Scattered <br />These areas are undisturbed area where the natural vegeta- <br />tion cover is still intact. These areas have few if any <br />Russian Knapweed or hoary cress plants interspersed in the <br />native vegetation.
