second or third growing season, indicating that the perennial species were present prior to that <br />point though not obvious. tf reclaimed areas have a low vegetative cover, including annuals, <br />after the first growing season, the area will be evaluatd for perennial species density. If the <br />density of perennial species (excluding noxious or problem weeds) is less than one per square <br />foot in a seeded area, the subject area will be reseeded using the appropriate permanent seed <br />mix. Concentrated shrub seeding or planting areas will be exempted from this evaluation since <br />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 Seneca <br />II-W Mine and the II-W South Extension area. Specifically, the following noxious weeks las <br />listed in Section V, CMLRD Guideline for the Management of Noxious Weeds on Coal Mine <br />Permit Areas) were identified on the 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 be <br />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 be <br />contacted for recommendations as to specific herbicides and application rates for the targeted <br />weeds. Recommendations specified on the herbicide label will also be strictly 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 />applicator. Upon obtaining the proper herbicide application equipment, 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 />31 Revised 1/99 <br />
