• Canada thistle <br />Field bindweed <br />Yellow toadf lax <br />Reclaimed areas or mine related associated disturbances such as roadsides and facilities <br />will be monitored for noxious weed infestations. Monitoring will be conducted either <br />through the formal revegetation monitoring program or as qualitative observations by <br />Seneca 11 Mine reclamation personnel. If noxious weed infestations occur at levels uh ich <br />may interfere with successful reclamation, or are detrimental to stand quality, need <br />control using herbicides will be implemented. A number of herbicides are available on the <br />market at this time and those proposed for Seneca II Mine are listed in Table 13-7. The <br />Colorado State University Cooperative Extension Service, or representative agent in Routt <br />County, will be contacted for recommendations as to specific herbicides and application <br />rates for the targeted weeds. Recommendations specified on the herbicide label will also <br />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 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 <br />application and ongoing control Will be through the Reclamation Department at the Seneca <br />11 Mine. <br />All applicators, including the Seneca II Mine reclamation personnel charged with <br />herbicide appiicat tan, wiit be proper Ly licensed andtor certified to apply restricted or <br />general use herbicides as per Colorado statute and certification and licensing procedures <br />administered through the Division of Plant Industry, Colorado Department of Agriculture. <br />A need control program has been in effect a[ the Seneca 11 Mine since 1987. <br />Controlled areas will be monitored for effectiveness of the treatments. Follow-up <br />treatments will be conducted as necessary. Because of the many variables that may impact <br />the effectiveness of the control program and the aggressiveness of certain ue ed s, <br />monitoring for control and retreatment are critical aspects. Ongoing revegetation <br />• monitoring end qualitative observation of reclaimed areas by reclamation personnel will <br />identify retreatment areas and any new areas of established weeds requiring control. The <br />qualitative monitoring will be conducted annually in order to evaluate progress being made <br />13-29 Revised 01/15/93 <br />
