Currently, the Army and USACE are performing cleanup simultaneously on IAAAP, with the Army remediating contaminants resulting from munitions production under the Defense Environmental Restoration Program (DERP) and USACE remediating contaminates resulting from the atomic energy program under FUSRAP.
The Feasibility Study (FS) for IAAAP was completed April 22, 2011. This study identified, developed and evaluated the remedial-action alternatives for remediating AEC contaminates.
The Proposed Plan (PP) for remediation was available for a 30-day public review at the Burlington Library and online starting April 22, 2011. A public meeting was held May 17, 2011, at the Comfort Suites Hotel and Conference Center in Burlington, Iowa, to present the FS/PP to members of the community. In the PP, USACE recommended Alternative 4, Excavation of DU-Contaminated Soil with Physical Treatment and Off-Site Disposal, along with Alternative S3, Decontamination/Replacement of Structures.
The FUSRAP Record of Decision (OU8 ROD) was completed in September 2011. This ROD outlines the remedial activities that will be undertaken at IAAAP to address contamination resulting from AEC activities. The OU8 ROD selected remedy included Alternative 4, Excavation of DU-Contaminated Soil with Physical Treatment and Off-Site Disposal, along with Alternative S3, Decontamination/Replacement of Structures. The main components of the remedy include:
· Excavation of DU-contaminated soil at Firing Sites 1 and 2; Firing Sites 3, 4 and 5; the Firing Site 6 Area; and the Firing Site 12 Area;
· Physical treatment of DU-contaminated soil excavated via soil sorting;
· Decontamination of structural surfaces and/or replacement of structural components (e.g., Building 1-11 floor grate and Building 1-63-6 air filters);
· Disposal of DU-contaminated materials at a properly permitted off-site facility.
The Remedial Design/Remedial Action Work Plan (RD/RAWP) was completed in February 2013. The RD/RAWP outlines a comprehensive process that follows the governing CERCLA and FFA requirements for implementing the selected remedy in the OU8 ROD. Work began under this RD/RAWP in summer 2013. The Pilot Study for soil-sorting method has been completed, and the excavation of the Firing Sites Areas has begun. Decontamination of the buildings at Line 1 was completed in July 2015.
In 2008, it was determined that the soil in two of the FUSRAP areas (Line 1 and West Burn Pads South of the Road) was specifically covered in the existing Army Records of Decision (OU1 Soils RODs). As a result, these areas required remediation by FUSRAP under the authority of the Army RODs as directed by the EPA.
Under the Army RODs, USACE has disposed of more than 30,000 cubic yards of contaminated material from Line 1 and the West Burn Pads South of the Road. USACE continues this remediation effort at Line 1. Remediation has been completed at West Burn Pads South of the Road. The Remedial Action Closeout Report will be issued once all FUSRAP activities within the Army RODs have been completed.
