WVDP Phase 1 CSAP• WMA 1 is approximately 4.4 acres. WMA 1 contains the bulk of the WVDP’s facilities,including the Process Building, the Vitrification Building, and supporting facilities. Alarge, deep excavation is planned for WMA 1 as part of Phase 1 DP activities. Theexcavation will remove contaminated facilities and address subsurface contamination thatis a source for the North Plateau Groundwater Plume, as described in Section 7.3 of thePhase 1 DP.• WMA 2 is approximately 14 acres. WMA 2 contains low-level radioactive waste watermanagement facilities, including various lagoons. A large, deep excavation is planned forWMA 2 as part of Phase 1 DP activities. The excavation will remove contaminated wastewater management facilities; Lagoons 1, 2 and 3; and associated subsurface soilcontamination. In addition, facilities outside the deep excavation, including Lagoons 4and 5, will be removed, as described in Section 7.4 of the Phase 1 DP.• WMA 3 is approximately 2.3 acres. WMA 3 contains the HLW tank facilities. Only verylimited contaminated facility removal is planned for WMA 3 as part of Phase 1 DPactivities; the HLW tanks will remain in place, as described in Section 7.5 of the Phase 1DP.• WMA 4 is approximately 10 acres. WMA 4 contains the Construction and DemolitionDebris Landfill (CDDL). There currently are no planned Phase 1 DP activities withinWMA 4.• WMA 5 is approximately 19 acres. WMA 5 includes a variety of waste-processing andstorage facilities. Removal of facilities, facility pads, and hardstands is planned for WMA5 as part of Phase 1 DP activities, as described in Section 7.6 of the Phase 1 DP.• WMA 6 is approximately 14.5 acres. WMA 6 contains a variety of support facilities.Removal of facilities, facility pads, and hardstands is planned for WMA 6 as part ofPhase 1 DP activities, as described in Section 7.7 of the Phase 1 DP. In addition,construction of a Canister Interim Storage Facility (CISF) is planned for the south end ofRev. 1 10
