. SENECA II MINE 2005 ANNUAL RECLAMATION REPORT 2005 DISTURBANCE AREA No additional acres were disturbed during 2005. However, the Seneca II mine area was reviewed and revised to accurately portray the categories of activities; the final disturbance boundary was revised to match the aerial photography disturbance; permanent roads and ponds were delineated. The total disturbed azea has been revised to 2,2993 acres. This acreage change is reflected on the CDMG Annual Report Form and is included in the text of the following report. The 2005 Reclamation Map portrays the revised disturbance boundazies. BAC%FILLING AND GRADING No backfilling occurred in 2005 at Seneca II mine. However, 15.3 acres of proposed permanent toads were ripped, graded and narrowed. SOIL AND SPOIL MONITORING SCC is required by Permit C-80-005 to monitor the salvage, storage, and redistribution of soil and spoil handling operations at Seneca II Mine. Spedfic pzograms include documenting soil recovery, verifying soil redistribution thickness, determining final graded spoil quality and soil fertility, evaluating plant rooting characteristics, recording the source of replaced soil, and completing an annual soil balance. The following sections present the soil and spoil monitoring data for the 2005 calendaz yeaz. • Soil Recovery Documentation No additional topsoil was salvaged since no new disturbance occurred. • Soil Pit -Spoil Femility -Spoil Quality No additional soil pit or spoil samples were collected in 2005. Sod fertility and spoil quality samples aze collected periodically from shallow postmine soil pits, which are randomly located using a S00-foot grid. The postmine soil pits aze also used to evaluate plant-rooting chazacteristics and to compaze soil/spoil profile data with site-specific revegetation data. Postmine soil pits axe placed within reclamation blocks that have been soiled and seeded for a minimum of three years. Similar minimum time frames are used for monitoring postailne vegetation. The permanent vegetation has generally established suffidentiy after three to four years to evaluate interactions between rooting characteristics and soil/spoil quality (Schafer et. al., 1979). Historical soil and spoil quality data aze presented and discussed in previous Topsoil and Spoil Motritoring reports (PCC, 1987 and 1989) and the Annua] Reclamation Reports (PCC, 1991, 7992, 1993, 1994, 1999, 2003) that have been submitted to the Division. •
