second or third growing season, indicating that the perennial species were present prior -to <br />that point though not obvious. If reclaimed areas have a low vegetative cover, including <br />annuals, after the first growing season, the area will'be evaluatd for perennial species density. ~ i <br />If the density of perennial species lexcluding noxious or problem weedsl~ is less than one per <br />square foot in a seeded area, the subject area will be reseeded using .the appropriate <br />permanent seed mix. Concentrated shrub seeding or planting areas will be exempted from this <br />evaluation since the intent is to keep herbaceous competition at a minimum. , <br />Weed and Pest Control A number of noxious weeds occur in the region surrounding the <br />Seneca 11-W Mine and- the II-W South Extension area. Specifically, the following noxious <br />weeks las listed in Section V, CMLRD Guideline for the Management of Noxious Weeds on <br />Coal Mine Permit Areasl were identified on [he mine permit area during baseline studies: <br />Canada thistle <br />Field bindweed <br />Yellow toadflax <br />Reclaimed areas or mine related associated disturbances such as roadsides and facilities will <br />' be monitored for. noxious weed' infestations. Monitoring will be conducted either through the <br />formal revegetation monitoring program or as qualitative observations by SCC reclamation <br />• personnel. If noxious weed infestations occur at levels which may interfere with successful <br />reclamation, or are detrimental to stand quality, weed control using .herbicides will. be <br />implemented. A number of herbicides are available on'the market at this time. The Colorado <br />State University Cooperative Extension Service, or representative agent in Routt County, will <br />be contacted for recommendations as to specific ~ herbicides and application rates for the <br />targeted weeds. ~ Recommendations specified on [he herbicide label will also be~ strictly <br />'followed. <br />Application of herbicides will be carried out by two primary agents, outside services or <br />- Reclamation Department personnel~of the Seneca II-W Mine: Outside services will consist of <br />either the Routt County Weed Control District resources or a private commercial herbicide <br />applicatpr. Uponobtaining the proper herbicide applicationequipment, primary application and <br />ongoing control will be through the Reclamation Department at the Seneca II-W Mine. <br />All applicators, including the Seneca II-W Mine reclamation personnel that are charged <br />•. <br />31 ~ ~ Revised 1/99 <br />
