previous Topsoil and Spoil Monitoring reports (PCC, 1987 and 1989) and the Annual Reclamation Reports (PCC, <br />1991, 1992, 1993, 1994, 1999,2003) that have been submitted to the Division. <br />• Wolf Creek Spoil <br />SCC is required to sample and analyze final graded spoil from the Wolf Creek mining area prior to soil replacement. <br />Spoil is sampled on a 300 foot horizontal grid and tested for pH, acid base potential (ABP), and soil salinity (EC). <br />Suitable spoil topdressing (subsoil) is replaced prior to soil redistribution where acid strata (pH <5 and ABP <_5) aze <br />encountered. The monitoring progam is outlined in ,Permit C-80-005 on pages 6-153, 6-153x, 6-164, and 9-40, <br />Tabs 6 and 9, Volumes 3 and 7. No final graded spoil samples were taken in 2003. Analysis for existing graded <br />areas can be found in the 1994 and 1998 Annual Reclamation Reports, (PWCC, 1995 and SCC, 1999). <br />2001 Soil Replacement Thickness <br />SCC is required by CDMG to closely observe and routinely inspect soil replacement thickness in the Wadge and <br />Wolf Creek reclamation areas at Seneca II Mine. This monitoring requirement is included in Permit C-80-005 as <br />Item 5 of the Topsoil Quality Con[rol Program, presented in Vol. 7, Tab 9, Att. 9-4, pages 9-41. Permit. Historical <br />soil replacement thickness information for the 1984 through 1992 reclamation blocks is presented in Permit C-80- <br />• 005, Table 9-4-3, Attachment 9-4; Tab 9 of the Second, Third, and Fourth Annual Topsoil and Spoil Monitoring <br />Reports for the 1987, 1988, and 1989 field seasons; and the Annual Reclamation Reports (PCC, 1990; PWCC, 1991, <br />1992, 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 data of 2000 <br />ARR and statistics. The mean value of topsoil replaced was 1.2 feet for the 575 sample areas that were measured. <br />Soil Balance <br />Seneca submitted the final soil balance as Technical Revision No. 3 ] on June 26, 1997 as the final reclamation - <br />topsoil management plan for Seneca II. Subsequently, the CDMG approved this final topsoil management plan on <br />December 9, 1997. Hence, no soil balance will be submitted with any further Annual Reclamation Report. <br />• 2 <br />
