<br /> <br />May 8, 1992 <br />Page 2 <br />In the event adverse field or weather conditions require salvaging of topsoil from the access <br />roads the topsoil will be windrowed to the side of the access road. The amount salvaged will <br />be dictated by the location of the road. <br />The backhoe pits will require excavating a hole approximately 15 feet deep and five feet wide <br />and 10 feet long. The topsoil will be placed adjacent to the test pit. Likewise, the excavated <br />material will be placed adjacent to the test pit on top of the excavated topsoil. Upon completion <br />of evaluating the test pit the excavated material will be placed back into the pit and the topsoil <br />will be replaced. <br />The auger borings will be approximately 80 feet in depth, however, this depth may vary due to <br />spoil depth in the mined out pits. The bedrock borings will be approximately 80 feet in depth. <br />Upon completion of the boring the hole will either be backfilled with the material form the hole <br />or the hole will be grouted from bottom to top. In the event a boring is converted into a <br />monitoring well, a completion diagram will be forwarded to the MLRD. The wells will be <br />monitoring wells only and do not require a well permit from the Division of Water Resources. <br />It is anticipated that the borings will intercept both spoil water in the area of the old pits, and <br />possibly water in the Wadge overburden. Please refer to both Twentymile Coal Company's and <br />CYCC's permit for a description of the spoil and Wadge Overburden aquifers. <br />Upon completion of the investigation the sites will be reclaimed by replacement of topsoil. The <br />sites will then be seeded with CYCC's approved pastureland seed mixture.
