Rob Zuber <br />April 19, 2016 <br />Page 2 <br />3) The entire length of the road to well MW -65 was inspected on foot. Some minor erosion <br />was seen in various places along the road, and this could potentially get worse over time. <br />Near the well (south end) significant erosion was seen. There is a rill 18 inches deep and 5 <br />to 6 feet wide, which precludes truck traffic on the road at this spot. Dr. Corley indicated <br />additional information on this road: <br />. - <br />• The Corley Company would like the road reclaimed. <br />• The road is rough in many areas; the Corleys only use ATVs to drive the <br />road. <br />• Dorchester tore up the road by using it when the ground was muddy. They <br />then repaired it with plant reject material rather than gravel. Per Dr. <br />Corley, this material did not last long on the surface. <br />Response: TCC has withdrawn its demand to reclaim the road as part of the Agreement. The <br />condition of the light -use road has changed very little over the years. EFCI utilized the road for <br />monitoring MW -65 from 1985 through mid -2015, and never had difficulty traveling the road in a <br />pick-up. The road is currently a track, and is adequate for future ATV access by the landowner. <br />4) Near the portal area, EFCI should remove a piece of steel pipe that is north of the <br />Magpie Diversion. It is in the vicinity of two other sections of steel pipe that EFCI recently <br />removed. <br />Response: EFCI will remove the piece of scrap steel pipe. <br />5) At the north end of the spur off of the road to MW -NW there are two features that need <br />to be researched by EFCI and discussed with the Division: a metal structure that could be <br />a large manhole (it is full of dirt except for the top three to four feet) and a small pile that <br />could be topsoil. <br />Response: EFCI believes that the manhole structure was constructed by the mine to access the <br />water line from the Corley Mine well. The manhole will be reclaimed by EFCI. The origin of <br />the small pile of soil is unknown, and there is no viable reason why a topsoil pile would be <br />placed there. Some of this material can be used to fill the manhole void, then the disturbed area <br />of the backfilled manhole and soil pile seeded. <br />6) Two sets of holes were inspected near the reclaimed Newlin Creek Topsoil Stockpile, <br />and they appear to be the result of subsidence. Some of these holes should be filled by <br />EFCI to ensure that the post -mining land use is met. <br />Response: EFCI does not regard the small subsidence holes an issue with respect to the <br />approved post -mining land use. In addition, the approved subsidence mitigation plan does not <br />address repair of these types of holes or cracks that are caused by subsidence. Repair of the <br />cracks/holes are not an issue with the landowner, since, as part of the Agreement, TCC has <br />withdrawn its demand that the subject subsidence cracks be filled. Repair of the subsidence <br />holes, therefore, is not an EFCI responsibility. <br />
