Experimental Practice becomes an award winning project
Working together, the Kentucky Department of Surface Mining Reclamation and Enforcement and the Office of Surface Mining approved the Stone Mining Company Experimental Practice that transformed a coal slurry impoundment into the Grants Branch Lake...a fishing lake/mountain resort facility in Pike County, Kentucky. The Experimental Practice allowed alternative requirements of the Surface Mining Law so the slurry impoundment could be left as a permanent structure. Under the Experimental Practice, the company created a recreational lake in lieu of covering the slurry impoundment with the required four feet of non-toxic earth material..

Coal Refuse Impoundment
The Stone Mining Company began using the impoundment in 1968. Coal refuse generated at an adjacent cleaning plant was deposited behind the large embankment. The original permit required that the slurry pond be reclaimed to a post-mining land use of forest land and industrial/commercial use. The success for this post-mining land use was based on completely filling the impoundment with slurry, and when the plant supplying slurry to the impoundment ceased operation other reclamation alternatives were examined. Working with the county government, a plan was developed to reclaim the site into a recreation area that would directly benefit the community. The Experimental Practice was approved in 1997 and work began converting the coal slurry impoundment into a water resources recreational facility.

Modifications to the structure
The elevation of the spillway was raised and the height of the embankment lowered in order to create usable flat land at the top and reduce the down stream slope of the dam. The entire face of the dam was covered with more than two feet of soil and grass was planted. Today the lake is approximately 21 acres and has 6,200 feet of shoreline. Stocked with more than 10,000 fish, it's a serene, peaceful setting complete with paved roads, parking, and picnic areas. When final bond is released, the land will be transferred to the county as a permanent public reclamation area.

The Grants Branch Lake and Recreation Facility has been recognized as a unique solution to the reclamation of a slurry pond. It has received the 1999 Governor's Environmental Excellence Award in Mining Reclamation- Eastern Kentucky, the 1999 Best Reclamation Award from the Pikeville Regional Office (jointly presented by the Kentucky Division of Surface Mining Reclamation and Enforcement and the Kentucky Coal Association), an Honorable Mention Award from the Interstate Mining Compact Commission, and a National Reclamation Award from the Office of Surface Mining.
