WVDP Phase 1 CSAPEXECUTIVE SUMMARYThe Phase 1 Characterization Sampling and Analysis Plan (CSAP) provides details about environmentaldata collection that will be taking place to support Phase 1 decommissioning activities described in thePhase 1 Decommissioning Plan for the West Valley Demonstration Project, Revision 2 (Phase I DP;DOE 2009).The four primary purposes of CSAP data collection are: (1) pre-design data collection, (2) remedialsupport, (3) post-remediation status documentation, and (4) Phase 2 decision-making support. Datacollection to support these four main objectives is organized into two distinct data collection efforts. Thefirst is data collection that will take place prior to the initiation of significant Phase 1 decommissioningactivities (e.g., the Waste Management Area [WMA] 1 and WMA 2 excavations). The second is datacollection that will occur during and immediately after environmental remediation in support ofremediation activities. Both data collection efforts have a set of well-defined objectives that encompassthe data needs of the four main CSAP data collection purposes detailed in the CSAP.The main body of the CSAP describes the overall data collection strategies that will be used to satisfydata collection objectives. The details of pre-remediation data collection are organized by WMA. TheCSAP contains an appendix for each WMA that describes the details of WMA-specific pre-remediationdata collection activities.The CSAP is intended to expand upon the data collection requirements identified in the Phase 1Decommissioning Plan. The CSAP is intended to tightly integrate with the Phase 1 Final Status SurveyPlan (FSSP). Data collection described by the CSAP is consistent with the FSSP where appropriate and tothe extent possible.Rev. 1xiii
