NORTH RIVER PIT WEED CONTROL PLAN <br />This Weed Management Plan has been prepared for the All Rite Paving & Redi-Mix, Inc. <br />North River Pit. Weed control methods will be carried out as described below. <br />Present Weed Species <br />Currently there are two major occurances of weed species present on the property. <br />They are kochia and Russian thistle, which are not recognized as "noxious" by the state. <br />Site inspections indicate that leafy spurge, Canada thistle, musk thistle and Russian <br />knapweed are likely present on the site in limited numbers. All of these weeds are <br />expected to be removed from the site during stripping. <br />Identify Prevention Methods <br />The following methods will be implemented in order to help prevent weed infestation <br />after reclamation is complete: <br />Prior to stripping, stockpiling or respreading of topsoil, the topsoil will be <br />inspected for weeds. If weeds are present, they will be removed. <br />• Equipment will be cleaned when moved from weedy to non-weedy areas, in <br />order to eliminate potential spreading of weed seeds. <br />• Vegetation will be established as soon as possible upon completion of <br />reclamation grading to help reduce the length of time the site is exposed to <br />possible weed infestation. <br />Post-Mining Monitoring <br />Once post-mining grades have been achieved and the site seeded for revegetation, the <br />site will be monitored for future infestations of noxious weeds. Monitoring will occur <br />twice per year. <br />Weed Elimination Methods <br />If weeds are identified during subsequent monitoring activities, the following actions will <br />be taken: <br />• Mowing twice during growing season; <br />• If mowing proves to be ineffective, herbicidal control will be employed. The type <br />of herbicide will be decided on a case-by-case basis with coordination of the local <br />Weed Control District and will be dependent on weed type. <br />Continued Monitoring <br />Weed monitoring at the site will continue until noxious weeds are satisfactorily <br />controlled. <br />
