Lost Run Phase 2

Lost Run Phase II is located in Section 30 of Ward Township in Hocking County and lies within the 14 digit HUC unit #05030204060010. Upstream AMD is generated from subsidence features, spoil blocks in side drainages of intermittent streams, fractured high walls, and slumped drift mine entries. Phase II of the Lost Run reclamation project consists of numerous alkaline addition systems spread throughout the headwaters of the Lost Run basin to buffer numerous AMD sources throughout the basin. Post construction monitoring is being collected at site LR00040. However, no pre-construction data was collected at this site. Therefore, reclamation results for this report are evaluated at the mouth of Lost Run (site LR00020). This site also represents water quality from Lost Run Phase I. For this report both Phase I and II of Lost Run are evaluated at the mouth of Lost Run at site LR00020. The design was completed by ODNR – DMRM ($63,979).
The treatment consisted of constructing a 7,650 square foot limestone leach bed, installing 1,300 linear feet of limestone channels, 140 linear feet of Limestone J-trenches, 14,250 square ft. of steel slag leach bed and 197 linear feet of a steel slag berm to add alkalinity to buffer acidity generated in Lost Run. The goal of the design was to reduce acid and metal concentrations discharging into Monday Creek. Construction was complete June 20, 2007 by Stimmel Construction for a cost of $489,910. One of the planned steel slag berms could not be constructed due to private landowner denying permission. The funding sources for this project were for the design was ODNR-DMRM and for construction was MCRP, ODNR-DMRM and Ohio EPA 319. Approximately 143 lbs/day of acid and 0 lbs/day of metals were prevented from entering into Monday Creek as a result of Phase I and II of the Lost Run AMD reclamation project.
