Little Raccoon Creek

 

Little Raccoon Creek is a 38.5-mile long stream in Jackson, Vinton and Gallia Counties, and the largest tributary of Raccoon Creek. Historic coal mining activities have caused extreme pollution of the waterway from acid mine drainage and sedimentation.  In the Little Raccoon Creek watershed, acid mine drainage (AMD) from abandoned underground and surface coalmine spoils and coal refuse, has degraded stream water quality and damaged fish and macroinvertebrate habitat.

Priority Sites

 

Flint Run is the largest contributor of AMD in the Little Raccoon Creek watershed. A ma­jority of this (90%) has been attributed to a 240-acre site in the headwaters. This site, called Bro­ken Aro, previously housed a coal preparation facility and mine tailings dump. Other major AMD contributors in this basin include Mulga Run, Buffer Run and Goose Run.

Flint Run East

 

Flint Run East is located in Section 28 of Milton Township in Jackson County. The project site is 56 acres and is located in Little Raccoon Creek next to Lake Milton. Flint Run East project is Phase I of the Flint Run Reclamation Project Lake Milton is Phase II. The project discharge was measured at the tributary draining the Flint Run East treatment site. The treatment approach for this site was to dewater the strip pits and install passive acid mine drainage treatment systems. The major consideration during the design process was to reduce groundwater infiltration into the valley coal refuse pile. The goal has been met 100%. Construction was complete Aug. 1, 2006, by Berridge Reclamation for a cost of $1,456,106.

 

Project Outcome

 

Initial results from the Flint Run East Project indicate, pH and net acidity have improved downstream of the reclamation site for 7.0 miles. Pre-construction data showed pH in the range of 2.9 – 6.7 at the project discharge and downstream.  However, after installation of the Flint Run East Project, postconstruction data shows pH in the range of 4.8 – 7.2 at the discharge, and downstream. The net acidity concentrations decreased 84 percent at the project discharge showing net alkaline conditions for 7.0 miles downstream. Approximately 803 lbs/day of acid and 107 lbs/day of metals were reduced from entering into Little Raccoon Creek as a result of this AMD reclamation project.

 

Lake Milton

 

Lake Milton is located in Section 28 of Milton Township in Jackson County. The project site is 155 acres and is located in Little Raccoon Creek next to the Flint Run East Project. The Lake Milton Project is Phase II of the Flint Run Reclamation Project, Flint Run East was Phase I. The project discharge was measured at the outlet from hothouse lake.  The treatment approach for this site was to repair the Lake Milton dam and to install a Successive Alkaline Producing System (SAPS) and a steel slag leach bed. The major consideration during the design process was the crucial need to treat the acid mine drainage in Upper Lake Milton to drain to Lake Milton before running into the steel slag bed downstream of Lake Milton. The goal of the design is to reduce 600 lbs/day of acid loading.  Problems occured with the valves in 2007, therefore this project only worked intermittently until Sept. 2007. Construction was complete September 5, 2006 by Stockmeister Enterprises Inc. for a cost of $961,536.

 

Project Outcome

 

As a result of the Lake Milton project the pH and net acidity has improved downstream of the reclamation site for 7.0 miles. Pre-construction data shows pH in the range of 3.0–6.7 downstream of the project. However, after installation of the Lake Milton Project, post-construction data shows pH in the range of 5.8–9.2 downstream of the project discharge. The net acidity concentrations decreased, showing net alkaline concentration for 7.0 miles downstream.  Approximately 1288 lbs/day of acid and 103 lbs/day of metals were reduced from entering into Little Raccoon Creek while the system was operating properly. Further evaluation will be completed next year.

 

State Route 124 Seeps

 

State Route (SR) 124 Seeps Project is located in Section 15 of Milton Township in Jackson County. The site is 7 acres and is located in the Little Raccoon Creek subwatershed.  The treatment approach for this site was to install several open limestone channels and conduct basic reclamation. The major consideration for this design was to establish positive drainage, remove several highwall impoundments, cover toxic materials, establish vegetations, and add alkalinity through the limestone channels. The goal of the design was to remove acidity from entering into Little Raccoon Creek. The project goal was met by100 percent. Construction was complete June 18, 2001, by Oldtown Coal Company for a cost of $315,490.

 

Project Outcome

 

As a result of the SR 124 Seeps project, the pH and net acidity has improved downstream of the reclamation site for 9.5 miles. Pre-construction data showed pH in the range of 2.9 – 6.7 downstream of the project. However, after installation of the SR 124 Seeps project, post-construction data shows pH in the range of 4.6 – 6.8 downstream of the project discharge. The net acidity concentrations decreased 89 percent at the discharge showing net alkaline conditions continuing for 9.5 miles downstream. Approximately 116 lbs/ day of acid and 15 lbs/day of metals were reduced from entering into Little Raccoon Creek as a result of this AMD reclamation project.

 

Mulga Run

 

Mulga Run Reclamation Project is located in Section 10 of Milton Township in Jackson County. The site is 6.8 acres and is located in the Little Raccoon Creek subwatershed. The treatment approach for this site was to install two steel slag leach beds and conduct a wetland enhancement project. The major consideration for this design was to attempt to treat entire basin with steel slag leach beds and wetland instead of treating all acid mine drainage sites in the basin. Mulga Run discharge was sometimes net alkaline; however, the site was also capable of producing acid spikes (3000 lbs/day) throughout the year. The goal of the design was to reduce 100 percent of the acid spikes and create consistent net alkaline water discharging into Little Raccoon Creek. The project goal was met by 100 present. One problem encountered during the project was one section of the township road and a private residence height was increased to reduce the flood risk adjacent to the project site. Construction was complete August 30, 2004, by Stockmeister Enterprises for a cost of $440,783.

 

Project Outcome


As a result of the Mulga Run Reclamation project, the pH and net acidity has improved downstream of the reclamation site for 2.1 miles. Pre-construction data showed pH in the range of 5.5 – 6.9 downstream of the project. However, after installation of the Mulga Run Reclamation project, post-construction data shows pH in the range of 6.8 – 7.1 downstream of the project discharge. The net acidity concentrations decreased, showing net alkaline conditions continuing for 5.7 miles downstream. Approximately 17 lbs/day of acid and 128 lbs/day of metals were reduced from entering into Little Raccoon Creek as a result of this AMD reclamation project.

 

 

Middleton Run - Salem Road

 

Middleton Run/Salem Road Project is located in Section 15 of Milton Township in Jackson County. The site is 60 acres and is located in the Little Raccoon Creek subwatershed.  The treatment approach for this site was to install open limestone channels, steel slag channels, reclamation, and a limestone leach bed.

Lake
Latrobe


Lake Latrobe is located on the Broken Aro Site, adjacent to the former Lake Hart, which was drained as part of the Flint Run East Project.  The dam of the lake is composed of mine spoil, which creates severe acid mine drainage as the lake water filters through it.  In 2008, the Raccoon Creek Partners plan to study this area and develop a plan for its reclamation.
