Seneca 11 Mine March 2011 <br />SL-5 Phase 11 Bond Release Request <br />• This application represents the formal request for Phase II Bond Release at Seneca II Mine of <br />219.7 acres of reclaimed area that complies with applicable revegetation success criteria set forth <br />in Rule 4.15.8. Map 1, Phase II Bond Request Areas, shows the location of the 219.7 acres <br />included in this request. <br />The amount of bond requested for Phase II release is $203,319. The rationale for this request is <br />documented in Attachment G, Bond Release Calculation. <br />• Summary of Reclamation and Management History <br />Reclamation (i.e., topsoil replacement and revegetation) was initiated in 1989 and continued <br />through 2003. This activity is documented in the Annual Reclamation Reports. <br />Reclamation management is a continuing effort that includes: <br />Rill and Gully Maintenance. Spring rill and gully surveys are conducted to identify erosional <br />• features resulting from spring snowmelt and runoff. The survey results are portrayed on maps <br />and submitted to the Division, which is followed up by on-the-ground maintenance to rectify the <br />problem areas. <br />Weed Control. Reclaimed areas and mine related disturbances, such as roadsides and <br />facilities, are monitored for noxious weed infestations. Monitoring is conducted through <br />formal revegetation monitoring program or as qualitative observations by Seneca II Mine <br />reclamation personnel. If noxious weed infestations occur at levels that may interfere with <br />successful reclamation, or are detrimental to stand quality, weed control is implemented. <br />Application of herbicides has been carried out by two primary agents, outside services or <br />Seneca II Mine Reclamation Department personnel. <br />Interseeding of Previously Seeded Areas. Interseeding is performed when necessary to ensure <br />adequate vegetative cover is maintained to meet the revegetation criteria set forth in the approved <br />PAP. Past monitoring at the Seneca II Mine shows that adequate perennial vegetation cover is <br />. well established by the second or third growing season, indicating that the perennial species were <br />present prior to that point though not obvious. If reclaimed areas have a low vegetative cover, <br />3
