• 2007 SOIL/OVERBURDEN SPOIL SAMPLING AT SENECA COAL 1.0 INTRODUCTION Sampling of reapplied soil and underlying regraded overburden spoil was conducted at Seneca Coal during 2007. The Yoast Mine and IIW (2W) Mine soil/overburden spoil sampling and evaluation was conducted by James Nyenhuis, Certified Professional Soil Scientist (ARCPACS #2753). The following is a list of all reapplied topsoil and regraded spoil sampling and evaluation completed during 2007. Yoast Mine Reapplied Topsoil/Overburden Spoil Sampling (October 2007): Two deep backhoe pits were dug at randomly selected, geographically distributed locations on reclaimed areas at the Yoast Mine. A total of ten samples were collected from the two backhoe pits and delivered to IML for standard analysis. The pit locations and samples were numbered: Y-TS-07-P1 (0 to 8", 8 to 17", 17 to 30", 30 to 50", and 50 to 72"), and Y-TS-07-P2 (0 to 6", 6 to 12", 12 to 18", 18 to 40", and 40 to 64"). The sampling included the reapplied topsoil to the spoil contact as well as the underlying spoil to a depth of 60 inches or deeper. The reapplied topsoil part of the pits (to a depth of 17" for Y-TS-07-P1, and to 12" for Y-TS-07-P2) received standard soil analysis. The mixed topsoil and regraded spoil part of the pits (from 17 to 30" for Y-TS-07-P1, and from 12 to • 18" for Y-TS-07-P2) received standard overburden analysis. The underlying regraded spoil part of the pits (from 30 to 72" for Y-TS-07-P1, and from 18 to 64" for Y-TS-07- P2) also received standard overburden analysis. A soil profile description was completed for each pit. The attached map shows all Yoast Mine reapplied topsoil backhoe pit locations. II_W__~2W) Mine Reapplied Topsoil/Overburden Spoil Sampling (October 2007): Three deep backhoe pits were dug at randomly selected, geographically distributed locations on reclaimed areas at the IIW (2W) Mine. A total of fifteen samples were collected from the three backhoe pits and delivered to IML for standard analysis. The pit locations and samples were numbered: 2W-TS-07-PI (0 to 6", 6 to 14", 14 to 24", 24 to 48", and 48 to 72"), 2W-TS-07-P2 (0 to 7", 7 to 15", 15 to 24", 24 to 35", and 35 to 72"), and 2W-TS-07-P3 (0 to 8", 8 to 18", 18 to 32", 32 to 52", and 52 to 72"). The sampling included the reapplied topsoil to the spoil contact as well as the underlying spoil to a depth of 60 inches or deeper. The reapplied topsoil part of the pits (to a depth of 14" for 2W-TS-07-P1, 15" for 2W-TS-07-P2, and 18" for 2W-TS-07-P3 received standard soil analysis. The mixed topsoil and regraded spoil part of the pits (from 14 to 24" for 2W- TS-07-P1, from 15 to 35" for 2W-TS-07-P2, and from 18 to 32" for 2W-TS-07-P3) received standard overburden analysis. The underlying spoil part of the pits (from 24 to 72" for 2W-TS-07-P1, from 35 to 72" for 2W-TS-07-P2, and from 32 to 72" for 2W-TS- 07-P3) also received standard overburden analysis. A soil profile description was • completed for each pit. The attached map shows all IIW Mine reapplied topsoil backhoe pit locations.
