• • Soil Recovery Documentation <br />No additional topsoil was salvaged since no new disturbance occurred. <br />• Soil Pit -Topsoil Fertility/Spoil Quality <br />No additional soil pit or spoil samples were collected within the Permanent Program permit area in <br />2007. <br />Pre-Law Wolf Creek Spoil. Minor Revision 57 (6/07) was submitted to present a potential plan for <br />remediation of the Wolf Creek pre-law area. The original plan estimated that approximately 10 tons <br />of limestone per acre would be required to adequately neutralize the area and promote acceptable <br />revegetation. In late August 2007, four (4) spoil samples were collected in the Pre-Law Wolf Creek <br />area to further refine the amount of lime needed to neutralize the acidic soil condition in order to <br />promote revegetation. The results indicated that somewhere around 1.2 tons per acre would be <br />needed to adequately neutralize the acidity. The soil analysis reports are included in the 2007 Soils <br />Report attachment. <br />SCC spread 87 tons of 200 mesh limestone over approximately 40 acres of regraded area in the <br />impacted area (~2.2 tons per acre) by aerial method. <br />• Soil Replacement Thickness <br />SCC was required by CDMG to closely observe and routinely inspect soil replacement thickness in <br />the Wadge and Wolf Creek reclamation areas at Seneca II Mine. This monitoring requirement is <br />included in Permit C-80-005 as Item 5 of the Topsoil Quality Control Program, presented in Vol. 7, <br />Tab 9, Attachment 9-4, pages 9-41. Permit historical soil replacement thickness information for the <br />1984 through 1992 reclamation blocks is presented in Permit C-80-005, Table 9-4-3, Attachment 9-4; <br />Tab 9 of the Second, Third, and Fourth Annual Topsoil and Spoil Monitoring Reports for the 1987, <br />1988, and 1989 field seasons; and the Annual Reclamation Reports (PCC, 1990; PWCC, 1991, 1992, <br />1993; SCC, 1994, 1995, 1996, 1997, 1998, 1999). In addition, Seneca conducted an exhaustive topsoil <br />redistribution depth sampling program during the summer of 2000. See Appendix 2000.1 for field <br />data of 2000 ARR and statistics. The mean value of topsoil replaced was 1.2 feet for the 575 samples <br />taken. <br />• Soil Balance <br />Seneca submitted the final soil balance as Technical Revision No. 31 on June 26, 1997 as the final <br />reclamation -topsoil management plan for Seneca II. Subsequently, the CDMG approved this final <br />topsoil management plan on December 9, 1997. Hence, no soil balance will be submitted with any <br />further Annual Reclamation Report. <br />• Soil Salvage, Storage and Replacement <br />Approximately 7.0 acre-feet of topsoil in Stockpile P was replaced on the 8 acre solid waste disposal <br />area. This represented all of the topsoil available in Stockpile P. <br />u <br />2 <br />
