WVDP Phase 1 CSAPcharacterization is outside the scope of the CSAP; data collection efforts in support of those twoactivities will be described in separate plans. However, CSAP pre-remediation data collectionwill provide information pertinent to waste stream characterization needs.In addition, the CSAP is focused on radiological parameters of interest. Chemical analyses arealso outside the scope of the CSAP. Any chemical analyses required to support ResourceConservation and Recovery Act (RCRA) decision-making will be described in separatedocumentation. Finally, the CSAP does not address Final Status Survey (FSS) data collectionrequirements. FSS requirements are described in the Phase 1 Final Status Survey Plan, Revision 1(DOE 2011) for the WVDP.The contents of this plan supplement and expand upon information contained in the Phase 1 DP.All CSAP field activities will be conducted consistent with the Health and Safety Plan (HASP)described by the Phase 1 DP. Some areas within the WVDP premises have been identified asradiological controlled areas; CSAP work within those areas will comply with pertinentradiologically controlled area requirements.Section 9.4.2 of the Phase 1 DP describes the U.S. Environmental Protection Agency’s (EPA’s)Data Quality Objective (DQO) process (EPA 2006), which is a seven-step process for developingtechnically defensible data collection programs. These seven steps are: (1) identifying theproblem, (2) specifying the decision, (3) determining the potential inputs to the decision, (4)defining the study boundaries, (5) developing decision rules, (6) establishing limits on decisionerrors, and (7) optimizing the final design. The CSAP does not follow the exact organization ofthe DQO process but does address each of the steps. The CSAP introduction states the problem tobe addressed: satisfying the data needs of the Phase 1 DP process. Section 2.0 provides thespecific decisions/objectives/questions that must be answered by CSAP data collection. Inputs tothose questions, study boundaries, decision rules and acceptable errors, and the final datacollection designs are presented in Sections 5.0, 6.0, and 7.0, and additional Waste ManagementArea- (WMA-) specific details for pre-remediation data collection are provided in the appendices.Rev. 1 2
