numbers relating them to the provided table on the map detailing the parcel history. Backfilling <br />and re -grading of the Yoast Mine took place between 1997 and 2007, generally being completed <br />within 180 days following the coal removal. The Phase I SL -6 requested areas were seeded <br />between 2004 and 2013. All areas have been reclaimed in accordance to the permitted <br />reclamation plan and approved post -mining land use. As-Builts of the Drainage profiles have <br />been included in this submittal in Attachment G to represent the drainages within the Phase I <br />areas. Also included in this submittal, in Attachment H, are the cross-sections of the reclaimed <br />pit areas. The locations of the cross-sections are referenced from Map 3. <br />PHASE III RELEASE AREAS <br />Reclamation (i.e., topsoil replacement and revegetation) in the Phase III request areas were <br />initiated in 2001 and continued through 2007 with approximately 10 acres of interseeding <br />conducted in 2009. This activity is documented in the Yoast Annual Reclamation Reports <br />submitted to CDRMS for these periods. Topsoil depth replacement information and revegetation <br />history are included in the Yoast SL -3 Phase II bond release application approved by CDRMS in <br />January 2012. Vegetation establishment was documented in formal vegetation sampling and <br />results reported in the SL -3 Phase II bond release document. <br />RECLAMATION MANAGEMENT <br />Reclamation management has been a continuing effort that includes: <br />Rill and Gull}, Maintenance. Spring rill and gully surveys are conducted to identify <br />erosional features resulting from spring snowmelt and runoff. The annual survey results <br />are portrayed on maps and submitted to CDRMS. The survey outcomes have been <br />f �' <br />followed up as necessary by maintenance and repairs to rectify identified areas found in <br />the survey and inspections. <br />Weed Control. Reclaimed areas and mine related disturbances, such as roadsides and <br />facilities, are monitored for noxious weed infestations. Monitoring is conducted <br />through the formal revegetation monitoring program or as qualitative observations <br />by Yoast Mine reclamation personnel. If noxious weed infestations occur at levels <br />that may interfere with successful reclamation, or are detrimental to reclaimed land <br />quality and management, weed control is implemented.
