St. Louis, MO (PRWEB) January 17, 2013
Throughout 2012, The Doe Run Company championed several remediation and repurposing efforts to return Missouris historic mining sites to productive use. As the largest lead producer in North America, Doe Run helps to revitalize these properties in ways that benefit the community, the environment and the company.
At Doe Run, we approach remediation as an opportunity to bring new purpose and greater value to old mine sites, said Chris Neaville, Doe Runs asset development director. By exploring innovative opportunities for these sites, weve helped create potential renewable energy sources, and recreational and industrial areas.
Currently, Doe Run is participating in a pilot project with MFA Oil Biomass LLC and the Missouri University of Science and Technology to plant Miscanthus grass (a biofuel crop) at the companys Mine 28 tailings site.
Were excited about working with the local community to revitalize these sites, said Neaville. These projects complement traditional remediation methods, such as covering mine tailings with new soil and reintroducing native plants to support local wildlife.
Right now, Doe Run is remediating several historical mine sites in St. Francois County, Mo., and Jasper County, Mo. For more than a century, mining companies extracted rich deposits of minerals found in these regions, helping to drive the nations industrial revolution and continued technological advancement. The remaining tailings, or sand-like particles of rock materials, contain less than one percent of lead and zinc by weight.
As the last remaining lead mining company in the region, Doe Run is working to restore several sites, including areas Doe Run obtained from other mining companies. In 2012, Doe Runs remediation crews completed work in the following areas:
St. Francois County, Mo.
St. Joe State Park. Currently owned and managed by the Missouri Department of Natural Resources (MDNR), St. Joe State Park is located in a region known as Missouris Old Lead Belt, about 60 miles southwest of St. Louis. By restoring these lands, Doe Run helps ensure that St. Joe State Park, which generates more than $ 2.6 million in tax revenue for the state annually, continues to attract thousands of visitors each year. Visitors participate in activities such as touring the Powerhouse Museum, ATV riding, swimming, biking and camping.
In 2012, Doe Run completed fencing to separate ATV riders from remediation efforts, ensuring both rider and worker safety. Additionally, crews covered tailings with gravel around the Powerhouse Museum to aid with surface access and stability in the area.
In all, Doe Run has completed significant work in St. Joe State Park, including replacing beaches in swimming areas with clean sand, removing chat from campsites and replacing it with clean gravel, and assisting the state with stabilizing the tailings dam and other areas.
National Pile. Doe Run has completed work at this site, which included enclosing the pile with rock, soil and landscaping. In 2013, Doe Run will also assist with water drainage at the site. NL Industries Inc. (NL), previously known as National Lead Company, operated a mine at the location through 1933 and then closed operations. In 1936, Doe Run purchased the mine and surface rights, but did not reopen the mill. The land has since been donated to the city of Park Hills to support an industrial park that features businesses such as Piramal Glass International Limited, MOCAP, Lee Mechanical, Ameren Missouri, Bulk Tank, and Sheet Metal Systems LLC.
Haney Park Soccer Field. Doe Run also worked with the EPA to remediate Haney Park Soccer Field, adjacent to National Pile. Haney Park hosts approximately 60 youth soccer games per year. In 2012, Doe Run began excavating soil near Haney Park, replacing it with clean soil and vegetation, and plans to complete remediation at the soccer field in early 2013.
Rivermines. While remediation of the chat pile at the Rivermines site was completed years ago, Doe Run continues to identify ways to improve this site. In 2012, the company completed construction of a water treatment pond, which will help treat water that drains off the site. Most of the remaining property is owned by Lead Belt Materials, a local company that repurposes chat and tailings as part of an asphalt mix.
Jasper County, Mo.
Doe Run is remediating three sites in Jasper County, which were owned by a former subsidiary, Kansas Explorations Inc., and have now been repurposed for agricultural use by private property owners. Doe Run completed soil replacement, rock cover and revegetation at the Snapp site in 2011, bringing this project to a close. At the Isherwood site, Doe Run finished remediation in 2012, which included planting in collaboration with the landowner.
Planning for the last site in the county, known as Jasper, is underway. The company is researching innovative ways to recover metals from tailings at the Jasper site, and has received approval from the EPA to begin a pilot program in 2013.
For years, these sites sat unused, and now we are seeing true purpose and productivity returning to these areas, said Mark Nations, mining properties manager. Doe Run will continue to explore uses of historic mining sites to make tomorrow better than today for the communities in which we operate.
