CHRONOLOGICAL HISTORY OF REVEGETATION <br />Areas revegetated prior to 2003 at the Seneca II Mine are shown on the Seneca Il acres seeded prior to 2003 map in <br />• the exhibits section of this report. Chronological History of Revegetation Activities in the 1995 Annual Reclamation <br />Report, SCC 1996. Areas revegetated during 1997, 1998 and 1999 are shown on drawing 5299-4, 1999 Annual <br />Reclamation Report. Areas seeded in 2003 are shown on the Seneca II 2003 Reclamation Map. Areas seedlrig in <br />2003 are shown on Seneca II 2003 reclamation map under "Maps" tab. <br />SEDIMENTATION POND SURVEYS <br />SCC is required by Permit C-80-005 to monitor sedimentation ponds for sediment storage capacities. This schedule <br />provides a sediment yield history and gives advance warning to operations personnel when sediment clean-out work <br />is required. In accordance with Rule 4.05.6(1 l)(c), SCC visually inspects each pond a minimum of quarterly each <br />year. During these inspections, any drastic change in sedimentation storage or sudden increase in a sediment delta at <br />the inlet to the pond could be detected which would require mitigation. <br />• Based on the 2003 survey, all sediment ponds have sufficient sediment storage, Additionally, all ponds have been <br />discharging in compliance with the approved NPDES permit effluent limitations. Yearly sediment delivery estimates <br />to the ponds aze considerably less than originally calculated, especially since the majority of the areas m these <br />watersheds have now been reclaimed and revegetated. <br />See 2003 Annual reclamation report for latest calculated annual sediment deliveries. Following the data shows 2003 <br />surveyed capacities of Seneca II sediment pond: <br />r 1 <br />LJ <br />
