PIKETON, Ohio – A regulatory dispute has erupted between Ohio state agencies and the federal Department of Energy (DOE) over the transfer of Parcel 4 at the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio. The Ohio Environmental Protection Agency (EPA), the U.S. Department of Energy, and the Ohio Department of Health (ODH) appear to be at odds over the adequacy of rules governing radiological contamination at Piketon, raising questions about the sufficiency of existing protocols and the potential public health implications.
