CX-271095: X-151 Contractor Office Trailer Complex, X-206L Parking Lot, and X-152 Site Operations Management Complex Disposition Project, 451.1a-101 Rev.1

In support of decontamination and decommissioning (D and D) at the Portsmouth Gaseous Diffusion Plant (PORTS) and the current U.S. Department of Energy (DOE) mission of preparing areas for industrial reuse at PORTS, DOE plans to deactivate, demolish, and disposition two trailer complexes and an asphalt parking lot: the X-151 Contractor Office Trailer Complex with the associated X-206L Parking Lot, and the X-152 Site Operations Management Complex.

Numerous structures have been installed at PORTS since 2012 to support D and D of the former uranium enrichment facilities at the site, including these two trailer complexes. These trailer complexes include trailers, storage containers, chillers, generators, and associated utilities. The proposed action includes D and D of the X-206L Parking Lot and related infrastructure such as remaining electrical utilities and stormwater infrastructure (e.g., catch basins, piping, and culverts).
