Description

  • Content Description: This Corrective Action Decision Document/Closure Report has been prepared for Corrective Action Unit 546, Injection Well and Surface Releases, at the Nevada Test Site, Nevada, in accordance with the Federal Facility Agreement and Consent Order (FFACO, 1996; as amended February 2008). Corrective Action Unit (CAU) 546 is comprised of two corrective action sites (CASs): • 06-23-02, U-6a/Russet Testing Area • 09-20-01, Injection Well The purpose of this Corrective Action Decision Document/Closure Report is to provide justification and documentation supporting the recommendation for closure of CAU 546. To achieve this, corrective action investigation (CAI) activities were performed from May 5 through May 28, 2008, as set forth in the Corrective Action Investigation Plan for Corrective Action Unit 546: Injection Well and Surface Releases, Nevada Test Site, Nevada (NNSA/NSO, 2008). The purpose of the CAI was to fulfill the following data needs as defined during the data quality objective (DQO) process: • Determine whether a contaminant of concern is present at a given CAS. • Determine whether sufficient information is available to evaluate potential corrective action alternatives at each CAS. The CAU 546 dataset from the investigation results was evaluated based on the data quality indicator parameters. This evaluation demonstrated the quality and acceptability of the dataset for use in fulfilling the DQO data needs. Because DQO data needs were met, and corrective actions have been implemented, it has been determined that no further corrective action (based on risk to human receptors) is necessary for the CAU 546 CASs. The U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office provides the following recommendations: • No further corrective actions are needed for CAU 546 CASs. • No Corrective Action Plan is required. • A Notice of Completion to the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office is requested from the Nevada Division of Environmental Protection for closure of CAU 546. • Corrective Action Unit 546 should be moved from Appendix III to Appendix IV of the Federal Facility Agreement and Consent Order. Analytes detected during the CAI were evaluated against final action levels established in this document. No analytes were detected at concentrations exceeding final action levels. However, contaminants of concern were presumed to be present in the subsurface soil at CAS 09-20-01. Therefore, the corrective action of close in place was selected as the preferred alternative for this CAS. Potential source material was removed from CAS 06-23-02; therefore, the corrective action of clean closure was selected as the preferred alternative at this CAS.
