Review of recently acquired geologic information in the northwest portion of the proposed <br />Cow Camp underground coal reserve indicates the depth to the Wadge Coal is much greater than <br />originally anticipated at ccu25. CCR designed the monitoring wells for this location for more <br />shallow conditions, and believes it would be prudent to postpone installing monitoring wells at <br />ccu25 due to the risk of failed well completions at depths greater than 2,000 feet, and because <br />mining of the reserves in this area is not anticipated for at least five years or longer. <br />• In order to gather adequate baseline groundwater information for permitting the first five years of <br />mining proposed at the Cow Camp reserve, CCR plans to construct three monitoring wells at <br />exploration borehole ccu23 within the next several weeks. The wells are to be completed in the <br />Wadge overburden, Wadge Coal, and Wadge underburden formations. These wells will be <br />monitored monthly for water levels, and quarterly for water quality following the same <br />monitoring plans currently being conducted at the existing monitoring wells. Each well will also <br />be tested for collecting aquifer parameters. CCR is confident the wells will provide adequate <br />baseline groundwater quality and quantity data to characterize groundwater within the Cow Camp <br />coal reserve where the first five -years of underground mining is being planned. <br />Please don't hesitate to contact me via phone at 929.913.9218 or by email at <br />jeochraii@peabodyenergy.com if you have any questions. <br />Sipeg ly, <br />tchran <br />r Environmental Hydrology <br />Peabody Investments Corporation <br />C: Brian Dunfee (PIC) <br />Jerry Nettleton (TCC) <br />Vern Pfannenstiel (PIC) <br />
