The Commonwealth of Kentucky Department for Facilities and Support Services, Division of Abandoned Mine Lands, is requesting bids for abandoned mine land subsidence remediation in Hopkins County under RFB-13-27, with bids due July 21, 2026 at 9:30 a.m. Central Time. A mandatory site visit is scheduled for June 30, 2026 at 10:00 a.m. Central Time at 410 South Highland Avenue, Earlington, Kentucky.

The scope encompasses exploration drilling to verify the #11 seam coal mine and assess subsidence damage on South Highland Avenue. Work includes drilling six-inch-plus diameter holes cased with PVC pipe to the coal seam (anticipated depths 55–70 feet, potentially extending to 80 feet), utilizing downhole cameras to document mine conditions, implementing methane monitoring protocols, and grouting operations. Contractors must provide their own water supply—a minimum 400 gallons per borehole for flushing at 20 gallons per minute flow rate with metered measurement—and all drilling and grouting equipment, including a water buffalo or tank with pump system and grout pump. Tremie tubes and pressure induction are not required.

Additional work includes excavation and remediation of two subsidence areas on the Willie Thompson property—one measuring approximately 40 feet by 45 feet and five feet deep, another in an adjacent ditch line—filled with Class II riprap and compacted. Portal closure work involves two mine openings on the southeast side of South Highland Avenue using wildlife-accessible closures approximately four feet across and two feet high. Portal closure operations are restricted to outside April 1–May 31 and August 1–November 14 windows.
