4D of Tabs 6 and 9, Volumes 3 and 7, permit C-80-005. No final graded spoil samples were taken in 1995. Analysis for existing graded areas can be found in 1994 Annual Reclamation Report, (PWCC 1995). 1995 Soil Replacement Thickness SCC is required by CDMG to closely observe and routinely inspect soil replacement thickness in the wedge and wolf Creek reclamation areas at Seneca II Mine. This monitoring requirement is included as Item 5 of the Topsoil Quality Control Program presented in Volume 7, Tab 9, Attachment 9-4, Page 9-41. of Permit C-80-005. Historical soil replacement thickness information for the 1984 through 1992 reclamation blocks is presented in Table 9- 4-3, Attachment 9-4, Tab 9 of Permit C-80-005, the Second, Third, and Fourth Annual Topsoil and Spoil Monitoring Reports for the 1987, 1988, and 1989 field seasons, and the Annual Reclamation Reports (PCC, 1988;.1989; 1990; 1992; PWCC,. 1993, 19941. Soil replacement depths were measured October 12, 1995 for reclaimed areas which had soil replaced during 1995. Three depth samples were Laken on Lhe Wedge mining block. Those measurements were 19.5, 11.0, and 12.0 inches for an average of 12.5 inches over 6.6 acres. Soil Balance scc is submitting the soil balance, as of December 1, 1995, with the Annual Reclamation Report as required by Permit C-80-005, Volume 12, Tab 13, Page 13-29c and as recommended by Section 2.04.13(2) of Colorado's Regulations for Coal Mining. The soil balance is completed to ensure soil is salvaged, stockpiled, and replaced as recommended and approved in the permit, and, if necessary, to readjust the soil salvage and redistribution thickness. The soil information is also used to update the soil volume information previously submitted with the 1999 Annual Reclamation Report (Pwcc, 1995) and to confirm the mean soil replacement thickness Eor the remainder of Che disturbance area at Seneca II Mine. The latest soil balance was also in responses to a mid-term review question and submitted as TA30 to C-80-005 on January 31, 1996. Soil Salvage, Storage and Replacement Soil salvage (dis turbancel areas and soil stockpiles sites as of December 1, 1995 are shown on Exhibit 9-3a, Topsoil Balance Plan (Current). The following technique was used to prepare this exhibit. The soil salvage area and existing soil stockpiles were transferred from the Seneca Ir Pit progress and reclamation digital file to a 1^=400' scale Existing Contours Map dated October 27, 1995, This disturbance area, provided by the Seneca II engineering staff, was confirmed by overlaying the black and white 1"=400' scale ortho 3
