"Solid waste in drums is buried at the Radioactive Waste Management Complex (RWMC) at Idaho National Engineering Laboratory."
2 January 1974, Idaho Falls, ID.

DOE description:
"The RWMC, a 144-acre waste storage area for low-level radioactive solid wastes, is divided into a transuranic storage area (TSA) and a subsurface disposal area (SDA). The TSA is designed for the interim storage of transuranic wastes. The waste is packed in specially constructed boxes or drums and is stacked on a sloped asphalt pad. During the stacking operation, an air-support building covers the area. After stacking is complete, the air-support building is removed and the area is covered with plywood, nylon-reinforced polyvinyl, and two to three feet of earth. It is planned to retrieve the TSA waste and transfer it to a federal repository when one is available. The SDA is an 88-acre, fence-enclosed portion of the RWMC. Various waste materials contaminated with non-transuranic radioisotopes are placed in pits and trenches in the SDA and buried directly in the soil."
