(AP) — Federal charges related to time card fraud are expected to be dropped for two former managers and a former supervisor of CH2M Hill Hanford Group after they agreed to pay civil fines. The settlement agreements were not an admission of liability by any of the three defendants nor a concession by the federal government that its claims were not well-founded, the Justice Department said. The settlement followed a jury decision this fall that four other former employees of CH2M Hill Hanford Group, also known as CHG, were not guilty of fraud charges. The tanks contain millions of gallons of radioactive waste left over from the production of plutonium for nuclear weapons, and the government is funding a multi-decade effort to clean up the wastes.
