samples were sent to Inter-Mountain Laboratories (IML) in Sheridan, Wyoming for <br />standazd overburden analysis. The samples were numbered 2W #1 through #28. The <br />attached map shows all 2W Mine regraded spoil sample locations. <br />IIW (2W) Mine ReaooGed Toasoil Samoline (July 2006): <br />Four deep backhoe pits were dug at randomly selected, geographically distributed <br />locations on reclaimed azeas at the 2W Mine. A total of seventeen samples were <br />collected from the four backhoe pits and delivered to IML for standard analysis. The pit <br />locations and samples were numbered: 2W!'S-06-P1 (0 to 6", 6 to 16", 16 to 36", and 36 <br />to 64"), 2W15-06-P1 (0 to 8", 8 to 24", 24 to 36", and 36 to 65"), 2WTS-06-P3 (0 to 8", <br />8 to 22", 22 to 40", and 40 to 64"), and 2WTS-06-P4 (0 to 7", 7 to 16', 16 to 32", 32 to <br />48", and 48 to 72"). The sampling included the reapplied topsoil to the spoil contact as <br />well as the underlying spoil to a depth of 60 inches or deeper. The reapplied topsoil part <br />of the pits (to a depth of 16" for 2WTS-06-P1, 24" for 2WTS-06-P2, 22" for 2WTS-06- <br />P3, and 48" for 2WTS-06-P4) received standazd soil analysis; and the regraded spoil, or <br />mixed topsoil and regraded spoil, part of the pits received standazd overburden analysis. <br />A soil profile description was completed for each pit. The attached map shows a112W <br />Mine reapplied topsoil backhoe pit locations. <br />Seneca II Mine Surface Material Samoline (various dates. 2006): <br />Ten (10) randomly distributed samples of surface layer material about one foot thick <br />were collected from a "revegetation problem azea" on the Seneca II Mine during 2006. <br />This area, about 47 acres in size, was previously mined and regraded but never topsoiled. <br />It was part of the "Pre-Law" (SMCRA 1977) azea on Seneca II, and the regraded spoil <br />material is from the Wolf Creek Formation. Although the area was reseeded in 1981, the <br />plant growth is currently sparse and of poor quality. An additional five (5) samples of <br />surface layer material about one foot thick were collected from an adjacent, previously <br />regraded but not topsoiled azea that currently has better plant growth and could <br />potentially serve as a soil "borrow azea". The adjacent area is about 5 to 10 acres in size <br />and the regraded spoil is from the Wedge Formation. Tom Dockstader collected the 10 <br />samples from the problem azea, and Jay fames collected the 5 samples from the adjacent <br />azea. The 15 samples were sent to IML for standazd analysis including acid-base <br />potential (ABP). <br />2.0 METHODS <br />Each azea to be sampled was delineated on a recent Seneca Coal photobase map. All <br />sample locations were randomly selected and geographically distributed across each area. <br />All locations were sampled by file spade and/or soil auger. A composite sample of the <br />appropriate depth interval was collected at each location. Samples were screened in the <br />field over a No.10 (2mm) screen to remove lazger, hard rocks. Sample depth was noted <br />for each location as well as other information if pertinent. Soil backhoe pits were located <br />and dug to at least five feet by Seneca Coal. <br />2 <br />
