Support the RCRA Facility Investigation Report
The goal of this project is to assist CH2M HILL Hanford Group, Inc. in preparing the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) report for the Hanford Site's 200 Area single-shell tank (SST) waste management areas (WMA). Pacific Northwest National Laboratory’s (PNNL) work scope includes writing sections and appendices for the RFI report and supporting PNNL data package technical reports.
CH2M HILL is responsible for completing a Phase 1 RFI report that integrates the following:
- Results of data-gathering activities and evaluations for all SST WMAs
- Results of groundwater monitoring and impact assessments that are based on Hanford Site groundwater models
- Conclusions and recommendations.
The RFI report will be a single document that contains all available information for the 200 Area SST WMAs and will be used to support SST retrieval and closure. Results from WMAs A-AX, C and U will be included as appendices to the RFI integrated report and will address the SST WMAs under the RCRA Corrective Action. PNNL researchers have performed several activities stated in the work plans and are uniquely qualified to write relevant parts of the RFI report. As they apply to SST WMAs, PNNL is including in the RFI the state of knowledge in the following areas: laboratory results, associated science activities, recharge, contaminant release, geology, geochemistry, past and current groundwater flow and contamination.
PNNL will produce several data package technical reports and numerous appendices and sections as direct input to CH2M HILL's RFI report. PNNL staff will also assist CH2M HILL by providing technical reviews of other appendices and sections of the RFI report. This work will ultimately be used to support SST retrieval and closure.
