February 1998 Hoyden Culch Mine "Phase 2 fs 3 Bond Reltase Application ~ Pape 4 <br />IS) Dates Reclamation Work Performed: <br />• • Map 1, Phase Il/Phase III Bond Release Map, includes the reclamation sequence <br />and shows the yeaz when reclamation of the mine site and facilities area was <br />completed. In general, reclamation at the Hayden Gulch Mine was performed <br />between 1979 to 1987, however, sedimentation ponds 001 and 002 were <br />reclaimed during October 1996. Work performed, were applicable, included <br />facility removal, backfilling, regrading, topsoil placement, establishment of <br />drainage control, and revegetation. <br />16) <br />• Reclamation activities completed at the mine followed the approved <br />reclamation plan. Various Annual Reclamation reports and DMG inspections <br />serve to document the effectiveness of the reclamation activities. <br />Subsequent to reclamation, HGCC performed vegetation sampling of the <br />reclaimed mine site and facility areas during 1990, 1993, 1996, and 1997. The <br />1993 vegetation sampling indicated an improvement in revegetation cover over <br />the 1990 sampling and overall excellent revegetative success (Hayden Gulch <br />Mine, 1993 Annual Report, HGCC, February 1994). The results of the 1996 and <br />1997 vegetation sampling aze included in Exhibit 1, Reclamation Study for <br />Final Bond Release. This exhibit contains the report, 1996 and 1997 <br />• Reclamation Study for Final Bond Release Report, prepared by Intermountain <br />Resources. Results of the studies confirm that specific reclamation success <br />standards for vegetative cover, production and species diverstry were met for <br />both yeazs using statistical equations approved by DMG. The data also <br />indicates that the shrub density standard of 200 stems per acre has been <br />achieved for the reclamation parcel. <br />17) Copies Of The Written Notice To Seek Release To Parties Identified In Rule 3.03.2(1): <br />• A copy of the proposed bond release application notification letter and a listing <br />of the interested parties identified in Rule 3.03.2(1) aze included in Section 2.0. <br />As required under Rule 3.03.2(1), written notification was sent to the interested <br />parties prior to filing this bond release request.
