Armstrong Coal seeks Corps permit for new deep mine

The U.S. Army Corps of Engineers office in Louisville, Ky., will be taking comment until Sept. 3 on a Section 404 Clean Water Act permit application from Armstrong Coal on a new underground mine in western Kentucky.

The project is located on tributaries and wetlands that drain to Smith Ditch, located south of Pride in Union County, Ky.

“The proposed project would result in discharges of fill and/or dredged material into ‘waters of the United States’ on the surface disturbance area for the Armstrong #9 West Underground Mine, pending approval under Kentucky Department for Natural Resources (KDNR) Division of Mine Permits (KDMP) permit #913-5017,” said a Corps notice. “The proposed work includes an underground mine operation in the Western Kentucky Number Nine (WKY#9) Coal Seam and construction of associated surface facilities. The operation to access the WKY #9 Coal Seam will include the construction of intake and return air shafts, a manshaft, and a slope entry.”

Surface facilities proposed within this project include internal access road, mine office/bath house, and associated parking, shop/warehouse, supply yard, a coal stockpile, and conveyor. The total area within the project boundary is approximately 127 acres.  

Streams, wetlands, and open water would be impacted from the construction of this mine and associated surface facilities. A total of 742 linear feet of intermittent stream would be impacted. Materials to be discharged into the stream include fill material needed to create a levee around a sediment basin, two 100-foot high-density polyethylene (HDPE) pipe culverts, and necessary backfill to set the culverts in place for the stream crossing.
