The U.S. Department of Energy (DOE), National Nuclear Security Administration (NNSA), proposed to demolish Buildings 11-10 and 11-30 at the Pantex Plant. While removing the asphalt from the concrete slab at Building 11-30 during demolition, unknown concrete sumps, manholes, and drainage troughs were discovered. Removal of the sumps, manholes, and drainage troughs has been added to the scope of project no. D&D-10-003-C and would require deeper excavation. The added scope would not require excavating outside of the boundary that was identified in the original scope. In addition, B&W Pantex personnel have taken core samples of the concrete to allow for appropriate waste determinations. Sampling protocol, based on information provided in the Final Resource Conservation and Recovery Act (RCRA) Facility Investigation Report, Zone 11, January, 2003, eliminated concerns related to potential explosives contamination in the sumps and drainage troughs.
