Lost Run Phase 1

Lost Run Phase I is located in Section 36 of Ward Township in Hocking County and lies within the 14 digit HUC unit #05030204060010. The site is located at the mouth of the first tributary to the west in the Lost Run subwatershed. Project area is less than five acres. Lost Run is a tributary to Monday Creek at river mile 16.08. The Lost Run area was providing recharge to underground mine complexes. The majority of AMD discharging in the lower portion of Lost Run occurred beneath the abandoned high walls, or near the perimeter of surface mine reclamation areas at the coal crop line. Seeps also occur in areas where overburden was deposited. The design was completed by ODNR–DMRM ($35,000).

The treatment consisted of constructing a 13,700 square foot limestone leach bed and installing 3,540 linear feet of limestone channels to treat acid mine drainage from five locations. The goal of the design was to reduce acid and metal concentrations discharging into Monday Creek. Construction was complete October 10, 2006 by Tucson Inc. for a cost of $475,000. Problems with the limestone leach bed were encountered during the summer of 2007. The system was modified and repaired August 2007.  Approximately 509 lbs/day of acid and 50 lbs/day of metals were estimated to be prevented from entering Monday Creek as a result of the Phase I AMD reclamation project in Lost Run. The funding sources for this project were ODNR-DMRM for the design and MCRP, ODNR-DMRM and Ohio EPA 319 for construction.
