The Corps of Engineers signed the “Record of Decision for Soils Operable Unit,” for the Luckey Site, on July 26, 2006. The record of decision (ROD) for the Soils Operable Unit identifies beryllium, lead, radium-226, thorium-230, uranium-234, and uranium-238 as FUSRAP-related constituents of concern in soils. The remedy for soils is the excavation and off-site disposal of FUSRAP-contaminated materials.
The Corps of Engineers signed the ROD for the Groundwater Operable Unit of the Luckey Site in 2008. The remedy in this groundwater ROD is monitored natural attenuation of groundwater. This means that groundwater wells are sampled annually for beryllium, lead, uranium and gross alpha/beta until sampling results show a progressive trend that indicates safe drinking water standards have been met. During the site soils remedial action, more frequent monitoring will be conducted to meet the requirements of the groundwater ROD. Land-use controls concerning site groundwater will be implemented during the monitoring period to ensure there is no new groundwater development or changes in groundwater use.
The Corps of Engineers awarded a contract for remediation of the Luckey Site in 2015 and initiated preparation of the remediation work plans. Remediation of the Luckey Site is beginning in 2017. Once soil remediation begins, the Corps will excavate FUSRAP-impacted soils to achieve the cleanup goals specified in the record of decision. Excavated soils will be shipped off-site for disposal at a licensed/permitted disposal facility.
In addition, the U.S. Army Corps of Engineers, Buffalo District, has released the “Explanation of Significant Differences for the Record of Decision for the Soils Operable Unit, Luckey Site, Luckey, Ohio.” The document is available in the Reports Section below. The explanation of significant differences outlines the current cost estimate for the soils remedy of $244 million, which is a significant change over the Soils Operable Unit ROD cost estimate of $59.4 million. The cost increase is attributed to:
- An increase in the estimated volume of contaminated soil.
- Extending the projected contaminated soil footprint beneath at least two unoccupied site buildings, which would require removal to fully address the soil contamination.
- Reexamining and increasing the cost for several work items based on lessons learned from other FUSRAP remedial actions and updated cost data.
