Description | From the Hazard AML office head north on route 15 for 0.2 miles, turn left onto Johnny Cox All-American Drive. Continue on this road for 2.1 miles, then turn left onto KY 15 north. Continue for 6.4 miles, then turn right onto KY 1067 east (Fifthteen Mile Creek Road). Follow KY 1067 for 1.8 miles, the site will be on the right. The site involves acid mine drainage that is coming from the Hazard No. 7, Hazard No. 8, and the Hazard No. 9 seam. Most of the discharge is coming from the Hazard 7 seam. The discharge from the Hazard No. 7 seam has saturated the hillside and then flows down the hill thru a small culvert and drain before entering Fifthteen Mile Creek. Based on the geology maps seam contours this is a low spot for the Hazard No. 7 coal seam. There has been extensive pre-law underground mining that is discharging from this location. On the Hazard No. 8 seam just above the Hazard No. 7 seam there is an existing highwall that has been auger mined with an existing pit of water that also continues to discharge into the same area that is saturated. On the Hazard No. 9 seam just above the Hazard No. 8 seam there is an existing highwall that has been auger mined with some discharge from the No. 9 seam coming over the wall into the mine pit on the Hazard no. 8 seam. This project will involve treating the discharge with limestone sand and limestone rock drainage ditches. A 60inch diameter pipe with headwalls will be constructed to handle the discharge which has the potential of a mine blowout in the Hazard No. 7 seam. A subdrain will be constructed above the Kenny Campbell home to collect surface and ground water and discharge the water into the 60inch culvert to protect the home. On the Hazard No. 8 seam the auger pit will be backfilled. The drainage from the auger holes will be collected and diverted to and area that is diverted away from saturated area and Kenny Campbell home. The auger holes will be backfilled with Class II rock. The backfilling of the auger holes openings shall be done between Nov 15th and March 31st. On the Hazard No. 9 seam the auger holes will be backfilled. The low elevation in the coal seam is directly above Tim Millers house and is causing him problems. The bench will be regraded to eliminate the retention pond and divert the water drainage from the auger holes thru rock drains to a constructed rocklined ditch to the existing pit on the Hazard No. 8 seam. The backfilling of the auger holes openings shall be done between Nov 15th and March 31st. If trees are cut in the area between April 1st and October 31st compensation for bat habitat will be necessary. Sediment control will be provided as necessary in all disturbed areas. Any permits deemed necessary will be obtained prior to reclamation activities. |
