at its source location on a bench approximately 15 feet vertically above the valley floor of Fish Creek. We also inspected the water well for the Hayes residence, which is an alluvial well located on Fish Creek. This well provides all but drinking water to the residence. A seismograph has been set up near the trailer by the U.S. Bureau of Mines to attempt to produce a detailed record of future seismic events should they occur. This equipment was installed by Mr. Peter Swanson on August 2, 1994 and results of monitoring to-date are not yet available. We then proceeded inside the residence to continue our discussions. Your concerns as I understand them are as follows: * How can your home be stabilized to prevent future damage? * Could this affect your 25 year home warranty? * Could this affect future land value? * Could your ability to establish a deep ground water well be impaired? The Rules and Regulations which govern coal mining are clear; coal mining may not cause damage or diminution of use which cannot be economically or technologically repaired or restored to a condition which existed prior to mining. This applies to the permit area as well as the area adjacent to the permit area. Although your property is some 1500-2000 feet outside of the area subject to surface subsidence, it is well within the Foidel Creek mine permit area. Therefore, mining impacts and/or effects of subsidence must be mitigated by Twentymile Coal Company. The Division believes at this time your home could be stabilized to prevent future damage using existing technology. We cannot speculate on whether this would affect your warranty or the future re-sale value of your property. Both of these possible impacts would require an affirmative demonstration at some time in the future. It is unlikely your ability to establish a deep groundwater well would be affected but this is difficult to determine unless we are able to monitor an existing well on your property. Other water monitoring in the vicinity should provide some indication should changes in the groundwater regime occur. Summary It is our understanding that you have sought legal advice and are discussing potential options with Twentymile Coal Company. Since the outcome of those options will determine to a great extent what the Division will do, we will await word from you on final agreements, if any, you reach with TCC before proceeding with monitoring and mitigation plans. Should you have questions or concerns, please call me.
