Conceptual Site Model - Argonne National Laboratory

WVDP Phase 1 CSAPA steel security fence surrounds the WVDP, the SDA, and miscellaneous other locations,including parts of WMA 10. It is made of galvanized chain link with galvanized steel pipe posts,with a spacing of 10 feet. The fence is seven feet high with a total length of 4.7 miles. Threestrands of barbed wire are stretched across the top of the fence. Figure I.1 shows the location ofthe fence along the border of WMA 10.Expanded Laboratory. The Expanded Laboratory is located south of the AdministrationBuilding. It was constructed during the early 1990s. The laboratory is 92 feet long and 50 feetwide, and consists of eight one-story modular units supported by 72 concrete piers. It wasmanufactured from light wood framing, metal roofing, and siding. An addition, 20 feet wide and50 feet long on a concrete foundation wall, was built on the east side of the laboratory. Thisfacility will be removed to grade during the work to achieve the interim end state.New Warehouse. The New Warehouse was built during the 1980s and is located east of theAdministration Building. It is a pre-engineered steel building, 80 feet wide, 250 feet long, and21.5 feet high at the roof peak, resting on about 40 concrete piers and a poured concretefoundation wall. The concrete floor is underlain with a gravel base.Former Waste Management Storage Area. This area is a lay-down area associated with the NewWarehouse.Parking Lots and Roadways. Two parking lots are located off Rock Springs Road: the MainParking Lot and the South Parking Lot. The Main Parking Lot has a total paved surface area of180,000 square feet and is covered with asphalt underlain with gravel. The South Parking Lotwith approximately 80,000 square feet of parking area is also paved with asphalt. A guardrailapproximately 1,200 feet long borders the lot along its southern, eastern and western sides.Roadways are constructed of a stone sub-base approximately eight-inches thick, covered withasphalt approximately four-inches thick. The total area of pavement or gravel surface withinWMA 10 is approximately 11 acres.Buried Infrastructure. Storm drainage from WMA 10 is carried by underground storm sewerlines to discharge points outside the WMA 10 boundary. Buried utilities also provide a pathwayfor storm drainage.Rev. 1 I-2
