MAP DESCRIPTION <br /> Map 1 —Phase III Bond Release SL-7 Delineation Map. This map shows all requested Phase III areas. <br /> These areas meet the minimum 10 year period for revegetation. <br /> Map 2—Phase III Bond Release SL-7 Location Map. This map shows the location of the mine permit with <br /> respect to the surrounding area. <br /> Map 3 — Phase III Bond Release SL-7 Permanent Features Map. This map shows all approved roads, <br /> ponds and the permanent drainage features. <br /> PHASE III BOND RELEASE DOCUMENTATION <br /> This application represents a formal request for Phase III Bond Release at II-W of approximately 367.0 <br /> acres of reclaimed lands (see Map 1). These reclaimed lands comply with applicable success and <br /> demonstration criteria set forth in Rule 4 — Performance Standards, and the approved II-W permit. The <br /> final amount of Phase II/III bond to be released will be calculated by the CDRMS but $650,000 was <br /> requested by SPL. <br /> SUMMARY OF RECLAMATION AND MANAGEMENT HISTORY <br /> Reclamation(i.e.,topsoil replacement and revegetation)was initiated in 1990 and continued through 2008 <br /> in the Phase III request areas. This activity is documented in the II-W Annual Reclamation Reports <br /> submitted to CDRMS. Topsoil depth replacement information and revegetation history are included in the <br /> SL-5 Phase II bond release application for the Seneca II-W mine approved by CDRMS in October 2014. <br /> Vegetation establishment was documented in formal vegetation sampling and results reported partially in <br /> the SL-5 Phase II bond release document with the remaining supporting documentation provided with <br /> SL-7 Bond Release Application. <br /> Reclamation management has been an ongoing effort that includes: <br /> Rill and Gully Monitoring and Maintenance - Spring rill and gully surveys are conducted to <br /> identify erosional features resulting from spring snowmelt and runoff The survey results are mapped <br /> and submitted to the CDRMS annually. The survey outcomes have been followed-up, as necessary, <br /> by on-the-ground maintenance and repairs to address any significant erosional features identified by <br /> the annual survey and inspections. <br /> Weed Control - Reclaimed areas and mining-related disturbances, such as roadsides and <br /> facilities, are monitored for noxious weed infestations. Monitoring is conducted through the <br /> formal revegetation monitoring program or as qualitative observations by Peabody <br /> Environmental staff or qualified contractors. If noxious weed infestations are identified as <br /> occurring at levels that may interfere with successful reclamation, or are detrimental to <br /> reclaimed land quality and management, appropriate weed control measures are implemented. <br /> Targeted weed control through application of selective herbicides is conducted by Peabody <br /> Environmental staff and/or qualified contractors in compliance with applicable regulations and <br /> procedures. <br /> 3 <br />
