Corrective Action Investigation Plan for Corrective Action Unit 552: Area 12 Muckpile and Ponds, Nevada Test Site, Nevada, Rev. 1

PDF Version Also Available for Download.

Description

Corrective Action Unit 552 is being investigated because man-made radionuclides and chemical contaminants may be present in concentrations that could potentially pose an unacceptable risk to human health and/or the environment. The CAI will be conducted following the data quality objectives (DQOs) developed by representatives of the Nevada Division of Environmental Protection (NDEP) and the DOE National Nuclear Security Administration Nevada Site Office (NNSA/NSO). The DQOs are used to identify the type, amount, and quality of data needed to define the nature and extent of contamination and identify and evaluate the most appropriate corrective action alternatives for CAU 552.

Description

Corrective Action Unit 552 is being investigated because man-made radionuclides and chemical contaminants may be present in concentrations that could potentially pose an unacceptable risk to human health and/or the environment. The CAI will be conducted following the data quality objectives (DQOs) developed by representatives of the Nevada Division of Environmental Protection (NDEP) and the DOE National Nuclear Security Administration Nevada Site Office (NNSA/NSO). The DQOs are used to identify the type, amount, and quality of data needed to define the nature and extent of contamination and identify and evaluate the most appropriate corrective action alternatives for CAU 552. The primary problem statement for the investigation is: ''Existing information on the nature and extent of potential contamination is insufficient to evaluate and recommend corrective action alternatives for CAS 12-23-05.'' To address this problem statement, the resolution of the following two decision statements is required: (1) The Decision I statement is: ''Is a contaminant present within the CAU at a concentration that could pose an unacceptable risk to human health and the environment?'' Any site-related contaminant detected at a concentration exceeding the corresponding preliminary action level (PAL), as defined in Section A.1.4.2, will be considered a contaminant of concern (COC). A COC is defined as a site-related constituent that exceeds the screening criteria (PAL). The presence of a contaminant within each CAS is defined as the analytical detection of a COC. (2) The Decision II statement is: ''Determine the extent of contamination identified above PALs.'' This decision will be achieved by the collection of data that are adequate to define the extent of COCs. Decision II samples are used to determine the lateral and vertical extent of the contamination as well as the likelihood of COCs to migrate outside of the site boundaries. The migration pattern can be derived from the Decision II samples, since the analytical results of those samples will show how far the contamination has travelled in the time period since activities at the site ended. Most of the data necessary to resolve the decisions will be generated from the analysis of environmental samples collected during the CAI for CAU 552. The general purpose of the investigation is to: (1) Identify the presence and nature of COCs. (2) Determine the vertical and lateral extent of identified COCs. (3) Ensure sufficient data is collected to support the selection of a corrective action compliant with all NDEP, ''Resource Conservation and Recovery Act (RCRA), Toxic Substance Control Act (TSCA)'', and DOE requirements. In addition, data will be obtained to support (IDW) disposal and potential future waste management decisions.
