This region (OU-4) includes Snow Creek and its floodplain from Highway 78 to the confluence of Snow and Choccolocco creeks. It also includes Choccolocco Creek and its floodplain from the backwater area upstream of Snow Creek to the embayment of Logan Martin Lake on the Coosa River.
Status
The EPA approved a Record of Decision (ROD) for this unit. The selected actions in the ROD will protect the public and environment from actual or potential releases of hazardous substance from OU-4.
Selected actions
Excavate soil with PCB contamination greater than 1 milligram per kilogram (mg/kg) on one residential property, dispose of that soil off-site and fill the area with clean soil.
Adopt corrective measures from the Resource Conservation and Recovery Act (RCRA) that were previously implemented at Oxford Lake Park softball fields, the softball field’s parking lot, the tennis court complex and the southwest portion of the park.
Excavate floodplain soil in the upper 0-6 interval if PCB concentrations are greater than 6 mg/kg on a surface weighted average, backfill excavated areas and dispose of contaminated soil off-site.
Implement creek bank soil stabilization in areas with minor, moderate and severe erosion where PCB concentrations are greater than 2.6 mg/kg. Sediment with PCB concentrations greater than 2.6 mg/kg will be dredged and disposed off-site. Natural sediment recovery will be monitored and observed long-term.
Implement institutional controls (ICs), including a soil management plan, to limit exposure to PCB-impacted soil left in place and protect the area’s long-term integrity.
Develop an institutional control implementation and assurance plan (ICIAP) that will set out plan specifics and measures to achieve the goals and identify who will implement, enforce and monitor each IC.
The EPA and Solutia are negotiating a Superfund settlement agreement. Once a settlement agreement is reached, it will be finalized in the form of a judicial consent decree.
