Hock Hocking NOI <br /> Attachment A <br /> This additional information has been provided based on the adequacy letter of November 3, <br /> 2014. <br /> 1 - The generator fuel tank is a steel tank of 500 gallon capacity and it will be placed in a <br /> standard metal stock watering tank of at least 600 gallon capacity. Both will be removed once the <br /> drilling project is completed. <br /> 2—Appendix A to the NOI is attached which shows the legal right of entry into the claims <br /> needed for this NOI. <br /> 3 - The blue steel door that is shown in Figure 1 of the NOI submittal is in place and will be <br /> locked every night after the work is finished underground and it will be locked after the project <br /> has been completed. <br /> 4—a) The fluid drilling may employ a polymer which will be added to the drill fluid. It will only <br /> be used if necessary and this polymer is safe and biodegradable. Its MSDS sheet is attached at <br /> the end of this Attachment A. It would be used in minor quantities to facilitate the drilling <br /> process, if needed. <br /> b) There will be no drill cuttings from the drilling since all drilling will be done by <br /> coring. The hole size is 2 IA inches in hole diameter. <br /> c) The water for the drilling operation is expected to use 4-6 gallons per minute during <br /> drilling and this water will be obtained directly from the mine ditch, which has been <br /> running approximately 330 gpm for many decades. The drilling fluid is expected to be <br /> minor and will be contained by placing 5 rows of coconut/straw waddles around each of <br /> the 5 drill sites. It will be placed so that all drill fluid will need to pass through these <br /> waddles to reach the mine ditch. <br /> 5 —The Hock Hocking Mine was started in quartzite veins in the very large and extensive <br /> Leadville Limestone formation and other lower Paloezoic Carbonate rocks, which are the Dyer <br /> and the Manitou Formation. The Leadville formation can be considered an aquifer but the water <br /> is only present in fractures. Water moves in fractures in this formation and also in the veins of <br /> quartzite which penetrated the formation. These veins were formed by super-hot hydrothermal <br /> solutions which rose up in the fractures in the Limestone. The Cooper Creek Fault is also within <br /> the mine area and some water moves along this Fault line. It is a reverse fault of pre- <br /> mineralization origin. As previously stated, the mine averages a flow of 330 gallons per minute, <br /> which is approximately 0.75 cfs. The records included in Appendix B show normal ranges of 0.5 <br /> cfs to 1.2 cfs each year. This water is clean and is sold to users downstream under the non- <br /> tributary water decree for this mine. The water that has exited the mine for decades has never <br />
