• SENECA II MINE <br />2006 ANNUAL RECLAMATION REPORT <br />2006 DISTURBANCE AREA <br />No additional acres were disturbed during 2006. The total disturbed azea remains at 2,2993 acres. <br />This acreage is reflected on the CDRMS Annual Report Form and is included in the text of the <br />following report. The 2006 Reclamation Map portrays the extent of the disturbance boundaries. <br />BACKFILLING AND GRADING <br />No backfilling occurred in 2006 at Seneca II mine. <br />A Phase I (backfill and grading) Bond Release application was submitted on May 24, 2006. A <br />proposed derision was prepazed by DRMS, dated December 27, 2006, which released partial <br />reclamation bond on 2,054.5 acres of backfilled and graded azea. Two areas were specifically <br />excluded from the bond release request including 125.8 acres in the East Wadge Pit and 67.4 aces at <br />the old Wolf Creek Pit (Pre-law area) both of which require additional grading to meet Phase I bond <br />release standazds. <br />SOIL AND SPOIL MONITORING <br />SCC is required by Permit C-80-005 to monitor the salvage, storage, and redistribution of soil and <br />spoil handling operations at Seneca II Mine. Spedfic programs include documenting soil recovery, <br />• verifying soil redistribution thickness, detemtining final graded spoil quality and soil fertility, <br />evaluating plant rooting characteristics, recording the source of replaced soil, and completing an <br />annual soil balance. The following sections present the soil and spoil monitoring data for the 2006 <br />calendar year. <br />• Soil Recovery Documentation <br />No additional topsoil was sah*aged since no new disturbance occurred. <br />• Soil Pit -Spoil Fertility -Spoil Quality <br />No additional soil pit or spoil samples were collected in 2006. <br />SoIl fertility and spoil quality samples are collected periodically from shallow postnilne soil pits, <br />which are randomly located using a 500-foot grid. The postmine soil pits aze also used to evaluate <br />plant-rooting characteristics and to compare soil/spoIl profile data with site-spedfic revegetation <br />data. <br />Postmine soil pits aze placed within reclamation blocks that have been soiled and seeded For a <br />tninimum of three years. Similar minimum time Erames are used for monitoring postmine <br />vegetation. The permanent vegetation has genera0y established suffiriendy after three to four <br />years to evaluate interactions between rooting characteristics and soil/spoil quality (Schafer et. al., <br />1)79). <br />• <br />
