Proposed Plan Available for Comments, Cherokee County Superfund Site, Cherokee County, Kansas, Baxter Springs and Treece Subsites
INTRODUCTION
The U.S. Environmental Protection Agency is releasing a Proposed Plan for an environmental cleanup in the Baxter Springs and Treece areas of the Cherokee County Superfund site. The action will be taken under the Comprehensive Environmental Response, Compensation and Liability Act, also known as the Superfund Law.
The EPA Proposed Plan recommends a cleanup approach for addressing the remaining non-residential mine waste that impacts the Baxter Springs and Treece areas. Some of the mine waste in these areas was addressed in a prior environmental cleanup.
EPA is asking for public comments on its Proposed Plan. The public comment period runs July 24 – August 22, 2006. Although EPA and the Kansas Department of Health and Environment (KDHE) are recommending a proposed action to address the remaining surficial mine waste, a final decision will not be made until EPA reviews comments from the public. After the comment period closes, EPA will make a decision, which will be published in a document known as a Record of Decision (ROD) Amendment. The ROD Amendment will also include a summary of EPA's responses to the comments received during the public comment period.
BACKGROUND
The Cherokee County Superfund site spans 115 square miles and represents the Kansas portion of the former Tri-State Mining District. The historic mining district encompasses 2,500 square miles in southeast Kansas, Northeast Oklahoma, and southwest Missouri. Mining for lead and zinc began in Kansas in the 1870s and continued until 1970. The site was placed on the National Priorities List, an EPA list of hazardous waste sites, in 1983 and many areas have subsequently been characterized and cleaned up.
The Cherokee County site is arranged into the following seven operable units (OUs) for administrative efficiency in conducting environmental cleanups:
- OU#1: Galena Alternate Water Supply
- OU#2: Spring River Basin
- OU#3: Baxter Springs subsite
- OU#4: Treece subsite
- OU#5: Galena Groundwater/Surface Water
- OU#6: Badger, Lawton, Waco, and Crestline subsites
- OU#7: Galena Residential Soils.
This Proposed Plan presents EPA's preferred alternative for the remaining mine waste at the Baxter Springs and Treece subsites. The preferred alternative includes the following:
- Excavate, consolidate, and/or cap surficial mine waste. Whether to excavate and consolidate, or cap mine waste in-place will largely depend on actual field conditions. The mine waste addressed by this plan includes all unremediated chat (sand to gravel-sized mine waste) piles, fine-grained tailings, and formerly excavated chat pile footprints.
- Cap subsidence pits, consolidation areas, tailings impoundments, and in-place chat/tailings areas with topsoil and clay caps.
- Encourage source reduction via responsible chat sales/uses before and during remedy implementation. The EPA plans to meet with chat owners to discuss responsible chat sales/uses and provide them with further information.
- Potentially utilize sub-aqueous mine waste disposal and post-remedial action groundwater monitoring.
- Re-contour and re-vegetate all disturbed areas and facilitate drainage and erosion controls.
- Adopt institutional controls to regulate use of mining areas in the future.
EPA estimates that the preferred alternative will take approximately eight to ten years to carry out and will cost approximately $66 million.
