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