CHRONOLOGICAL HISTORY OF REVEGETATION Total areas revegetated prior to and in 2004 at the Seneca II Mine are shown on the Seneca II 2004 Reclamation map in the exhibits section of this report. Further details aze presented in: • Chronological History of Revegetation Activities in the 1995 Annual Reclamation Report (SCC 1996) • Areas revegetated during 1997, 1998 and 1999 are shown on drawing 5299-4, 1999 Annual Reclamation Report. • Areas seeded in 2003 aze shown on the Seneca II 2003 Reclamation Map. SEDIMENTATION POND SURVEYS SCC is required by Permit C-80-005 to monitor sedimentation ponds fox sediment storage capadties. This schedule provides a sediment yield history and gives advance warning to operations personnel when sediment clean-out work is required. In accordance with Rule 4.05.6(11)(c), SCC visually inspects each pond a minimum of quarterly each yeaz. During these inspections, any drastic change in sedimentation storage or sudden increase in a sediment delta at the inlet to the pond could be detected which would require mitigation. Based on the 2004 survey, all sediment ponds have sufficient sediment storage. Additionally, all ponds have been discharging in compliance with the approved NPDES permit effluent litnitadons. Yearly sediment delivery estimates to the ponds are considerably less than originally calculated, since the areas in these watersheds have now been reclaimed and revegetated. Following the table lists the 2004 surveyed capacities of Seneca II sediment ponds: Table 04.2 Sediment Pond Capacities Pond Number 2004 Ca aci Minimum Allowable Water Stor 002 154.7 ac.ft 106.9 ac.ft. 003 4.3 ac.ft 2.1 ac. ft. 004 6.2 ac. ft. 3.0 ac.ft. 008 6.4 aafi. 2.9 ac.ft. From the past history of sediment delivery to all of these ponds there is adequate sediment storage capadty available. STOC% TAN1i;S There aze 12 existing stock tanks in the Seneca II mined/redaimed azea and aze all classified as permanent and are certified annually. No new stock tanks were constructed during the 2004 season. I•
