Pursuant to the Colorado 1996 Noxious Weed Law and additional 2003 <br />regulations, SCC has prepared a noxious weed management plan. The plan was prepared in <br />consultation with Colorado State University Cooperative Extension Service and Routt County Weed <br />Control Department <br />The list of plants classified as noxious weeds are identified in the Colorado Noxious Weed Act, 33- <br />5.5-101 to 119, CRS 2003. The noxious weeds are categorized as "A", "B" or "C" plants. No "A" <br />listed species have been observed at the Seneca II Mine. SCC conducts annual monitoring to insure <br />that no "A" list plants go undetected. Several species from the "B" and "C" lists have been <br />identified within the Seneca II permit boundary. In addition, severe) invasive and highly competitive <br />species not listed by the State are found on the Seneca II Mine; these species will be managed as <br />deemed appropriate by SCC personnel. The following weed species have been identified at the <br />Seneca 11 Mine through vegetation studies and field observation. <br />Black henbane Hounds tongue <br />Bull thistle Kochia • <br />Canada thistle Leafy Spurge <br />Common cockleburs Perennial pepperweed <br />Common mullein Russian olive <br />Curly cup gum weed Russian thisde <br />Curly dock Scotch thistle <br />Dalmatian toadflax Whitetop, Hoary cress <br />Downy brome, cheatgrass Yellow toadflax <br />Field bindweed <br />Reclaimed areas or mine related disturbances such and roadsides and facilities will be monitored for <br />noxious weed infestations. If noxious week infestations are observed, then the SCC reclamation <br />staff will implement the appropriate control strategy. If chemical control is required, application of <br />herbicides will tre carried out by either a private commercial herbicide applicator or SCC reclamation <br />staff. All applicators, including the Seneca II Mine reclamation personnel charged with herbicide application, <br />will be propedy licensed and/or certified to apply restricted or general use herbicides as per Colorado statute <br />and certification and licensing procedures administered through the Division of Plant Industry, Colorado <br />Department of Agricuhure. <br /> • <br />Noxious weed species will be controlled as follows according to the label instructions of each herbicide. <br />TR37 13-24 Revised 04/05 <br />
