Enclosed are the <br />results of this year of monitoring piezometer holes. The holes were placed as described <br />in the plan submitted to the Division in the letter dated December 8, 2003. See <br />enclosed map for detailed locations. <br />All "A" holes were completed to bedrock and have a perforated casing over the entire <br />depth. These holes (7 total) and one other hole were drilled and completed with <br />perforated PVC as soon as approval was granted in January of 2004. There were no <br />surprises on depth to bedrock. The holes are labeled on the attached map as Holes A-1 <br />through A-8. This showed that the geology of the shale getting very close to the surface <br />south of the permit area was proven since Hole A-7 was only 8 feet from the surface. <br />The gravel increases in thickness to the north until depths of 60 feet or more are <br />reached in Phase 1 (furthest north). The dip of the contact between the gravel and the <br />shale was also shown to be what was predicted: a slight dip to the northeast. <br />All holes were capped at the surface and marked to prevent surface damage. The holes <br />were checked weekly at the same time of day for water levels. This occurred from <br />April 26, 2004 to the current date. Samples of wells were obtained to determine pH <br />and specific conductance. The results of this testing are enclosed. <br />Al] "B" holes (4 total) will be drilled and completed as soon as the first year of <br />monitoring and evaluation of the "A" holes has been approved. <br />In the Petition to mine in Phase 1, a strong case was made to show that it was virtually <br />impossible that groundwater could be anywhere near the surface in the ls` 4 mining <br />phases. The Board agreed to allow mining to 13' depth for the Is` year. As the <br />
