PIKETON, OH - Official reports from the Portsmouth Gaseous Diffusion Plant highlight ongoing deactivation and cleanup efforts, but recent incidents reported by local residents are raising significant questions about the immediate environmental and health impacts of these activities. The plant's latest management update, presented by the Department of Energy (DOE), Ohio EPA, and the Ohio Department of Health, details progress in water treatment, waste placement, and building deactivation.
The plant's data indicates a cumulative total of 619,759,691 gallons of water treated, with 1,088,944 gallons treated in the week ending May 13, 2025, from various sources including Trains A, C, D, and groundwater. Waste placement at the On-Site Waste Disposal Facility (OSWDF) has also continued, with 405,909 cubic yards of soil and 206,207 cubic yards of debris placed as of May 13, 2025. Cell 2 of the OSWDF became operational on May 7, 2025, and Cells 1, 4, and 5 are operating at 98% capacity. Excavation for Cells 3 and 6 is complete, with select fill placed and clay layer installation initiated.

However, these operational metrics contrast sharply with direct accounts from the community. On May 9, 2025, residents in the vicinity of the plant reported a pervasive and strong odor. Our chief investigative journalist, Jason Salley, described the smell as akin to "pencil lead." He reported experiencing burning and irritation in his lungs and throat, with his son, who was also present along Hodge Lane and Happy Hollow Road, reporting similar symptoms. Such incidents raise immediate concerns about air quality and potential acute health effects on nearby populations.
The official update outlines substantial work on the X-326, X-333, and X-330 Process Buildings, including the removal of surface pads, underground utilities, and transite panels. For instance, exterior transite removal from the X-333 Process Building began on April 15, 2025, and is 2.1% complete, involving over 16,000 panels. Pre-demolition activities for the X-333 building are reported as 82% complete overall. While these deactivation efforts are underway, the disturbance of potentially contaminated materials necessitates stringent environmental controls and monitoring to prevent off-site impacts.
The Depleted Uranium Hexafluoride (DUF6) Project also continues, with 368 cylinders processed this fiscal year towards an annual goal of 456 as of May 19, 2025. The processing of such materials inherently carries environmental considerations.
The recent odor incident and associated health complaints underscore the importance of transparent communication and robust environmental safeguards at every stage of plant operations. The ongoing cleanup and deactivation processes are complex and involve hazardous materials, making it critical to address any and all community concerns regarding potential emissions and their impact on public health.
