custom built liner. This would require the services of a local contractor with a track <br />hoe or other heavy equipment. Interim water would need to be provided using a <br />temporary tank. Water would be hauled by truck to the site. The power line and <br />___ telephone line to John=s house would not be affected by this permit application <br />In the event that subsidence cracks damage any barbed wire fence within the <br />permit area (a fencepost could be dislodged ~r strands of barbed wire could stretch <br />and break or sag), National King Coal, LLC would be happy to fix said fences without <br />charge to the landowner or will reimburse the landowner for any repairs necessary. <br />Damage to the two-track dirt roads could occur if a subsidence crack were to <br />intercept the road. Any cracks of this nature could be easily filled with loose dirt or <br />gravel at National King Coal's expense; however, due to the present condition of the <br />road, cracks of this nature would be virtually unnoticeable. <br />The buildings and structures on and around the surface facility area of the <br />mine will not be damaged by subsidence because there are no minable coal seams <br />beneath this area. <br />The Huntington Irrigation Ditch and the adjacent surface area have been <br />inspected on a quarterly basis since 1981 by a qualified person for evidence of <br />subsidence -caused by underground mining. Results of these inspections are <br />reported to the Colorado Division of Reclamation, Mining 8v Safety. Quarterly visual <br />inspections of the Huntington Ditch to date have not indicated evidence of damage, <br />-nor -have -they indicated that -water is lost to the mine via surface fracturing. <br />Quarterly inspections of the Crawford Irrigation Ditch will commence once mining <br />and pillaring operations have been conducted in that area. <br />Field observations -indicate that -surface subsidence features are present above <br />abandoned portions of the mine. These features are in the form- of cracks which are <br />typically 4" to 6" wide and may be several hundred feet long. These cracks tend to <br />parallel pillared out mining sections. National King Coal, 'LLC will continue to <br />monitor these cracks on a quarterly basis. Should visual inspection determine that <br />a subsidence crack is approaching a possible intercept with the ditch, the location of <br />the crack and its relation to the ditch will be mapped and monitored closely. Survey <br />monitoring stations are for mapping purposes only. Should it appear eminent that <br />the ditch and a subsidence crack will intersect; the effected portion of the ditch will <br />be lined with flexible plastic conduit or other means equally effective to ensure the <br />continuous and unrestricted flow of water. <br />At bast one .month prior to retreat mining ..near the .Marc Crawford house., <br />subsidence monitoring monuments will be placed and surveyed in near the house by <br />a registered surveyor in such a way that subsidence can be detected from a survey <br />monumeet outside -the -affected -area of mining, should it occur. These monuments <br />will be surveyed quarterly for two quarters following the time that pillars have been <br />extracted from the area. These monuments will then be monitored annually for two <br />years to assure -that no subsidence -has occurred. The monuments will then remain <br />in place in the event that future questions arise concerning subsidence. Location of <br />these monuments and the structures they are to monitor are shown on Map King I- <br />013. <br />In the event that any of the aforementioned ditches, pipelines or utilities were <br />damaged between regular National King Coal inspections, the landowner will <br />pr-obably -become aware immediately. They will, in turn, notify us immediately. <br />National King Coal, LLC King I Mine <br />Section. 2.05,6 <br />Page 4 February, 2007 <br />
