2005 SOIL AND REGRADED OVERBURDEN SAMPLING AT SENECA COAL <br />1.0 INTRODUCTION <br />Soil and regraded overburden (spoil) sampling was conducted at Seneca Coal during <br />2005. The sampling and evaluation was conducted primarily by James Nyenhuis, <br />Certified Professional Soil Scientist (ARCPACS #2753). The spoil sampling completed <br />during July 2005 was done by Seneca Coal personnel. The following is a list of all <br />reapplied topsoil and regraded spoil sampling and evaluation completed during 2005: <br />Yoast Mine Reapplied Toasoil Sampling (September 2005): <br />Three deep backhoe pits were dug at randomly selected, geographically distributed <br />locations on reclaimed areas at the Yoast Mine. A total of thirteen samples were <br />collected from the three backhoe pits and delivered to Inter-Mountain Laboratories, Inc. <br />(IML) in Sheridan, Wyoming, for standazd analysis. The samples were numbered: YTS- <br />OS-P1 (0 to 6", 6 to 16", 16 to 34", and 34 to 60"), YTS-OS-P2 (0 to 7", 7 to 18", 18 to <br />29", 29 to 48", and 48 to 72"), and YTS-OS-P3 (0 to 12", 12 to 24", 24 to 44", and 44 to <br />64"). A soil profile description was completed for each pit. The sampling included the <br />reapplied topsoil to the underlying spoil contact as well as any underlying spoil to a depth <br />of 60 inches or deeper. The attached map shows all Yoast Mine reapplied topsoil <br />backhoe pit locations. <br />2W Mine Reapplied Toasoil Sampling (September 2005): <br />Three deep backhoe pits were dug at randomly selected, geographically distributed <br />locations on reclaimed azeas at the 2 W Mine. A total of eleven samples were collected <br />from the three backhoe pits and delivered to IML for standard analysis. The samples <br />were numbered: 2WTS-OS-P1 (0 to 10", 10 to 22", 22 to 38", and 38 to 62"), 2WTS-OS- <br />P2 (0 to 7", 7 to 20", and 20 to 60"), and 2WTS-OS-P3 (0 to 6", 6 to 16", l6 to 36", and <br />36 to 60"). A soil profile description was completed for each pit. The sampling <br />included the reapplied topsoil to the underlying spoil contact as well as any underlying <br />spoil to a depth of 60 inches or deeper.

The sampling was conducted by Seneca Coal personnel and <br />each sample consisted of a composite of the upper two feet of regraded spoil material at <br />each respective sample location. The samples were collected and delivered to IML in for <br />standazd analysis. The samples were numbered 2W-OS-OI through 2W-05-45.
