Redevelopment at the Site

Sustainability through re-use or recycling of Site materials is another focus for the remedial action. Trees removed from the work areas during construction are segregated from other wastes to allow re-use and recycling where possible. Root balls from vegetative clearing may have contaminated soil attached, and are transported to the Central Mill Repository, but waste trees and other wood debris are available for mulching. Sampling and analysis of the chipped waste tree and wood debris material is performed, and results indicate concentrations of lead, cadmium and zinc are well below the cleanup goals and Regional Screening Levels for residential soil. From the Distal 7 North Site alone, over 2,000 cubic yards of mulch was provided to a local company for use as mulch. Remedial activities at the Distal 7 South Site have yielded 2,115 cubic yards of mulch.

The cleanup addresses residential relocation and sale of chat (a mining waste). EPA does not own any chat and will not purchase any chat. However, it is assisting chat sale participants, including the Quapaw Nation and local chat processors, as part of the Site’s Superfund remedy. Approximately, 17 percent of the source materials removed were purchased directly from property owners by local processors (with transport provided by EPA) for use.

Residential, commercial and public uses continue on several cleaned up properties. Reuses for properties currently undergoing cleanup are typically agricultural or rural. To date, workers remediated 2,940 properties under OU2.
