I-3.2 CSA DESCRIPTION I-3.2.1 General Description The CSA is used to store non -explosive, non -radioactive hazardous wastes at Site 300. It is located at Building 883 in the General Services Area near the southern boundary of Site 300 (Figure I-34). I-3.2.2 Physical Description The CSA is a covered, concrete pad approximately 49.5 ft x 35 ft. A 6 -in. (minimum), concrete curb surrounds the slab to contain any spills or run-ons. The open-air Facility has a flat roof constructed of galvanized, corrugated steel supported by 4 -in. steel pipe columns and open -web steel joists. The layout of the CSA is shown in Figure I-34. Although the CSA is not located in a flood zone, run-on control structures, including a roof, grades sloping away from the unit, and storm drains, have been provided to protect the waste containers from storm water. The CSA flooring is graded toward a sump, and the unit is designed to provide secondary containment. Waste containers containing free -liquids are stored in portable secondary containment units to provide additional control of potential spills. The paving around Building 883 was constructed to facilitate easy and safe access of forklifts and other equipment bearing waste containers to the CSA. This construction minimizes the risk A hazards during loading and unloading operations. A 6 -ft -high cyclone security fence encloses the perimeter of the CSA. The gate to the CSA is locked when the Facility is unattended. Operations at the CSA are limited to storage in closed containers. The only operations allowed in the CSA where open containers may be present are inspection, sampling, and hazardous waste transfer operations. I-3.2.3 Description of the Wastes Handled [-3.2.3.1 Wastes Stored at the CSA LLNL's research activities generate a variety of waste types typically in small quantities.
