Enforcement Letter issued to CH2M Hill Hanford Group, Inc., related to Quality Improvement Deficiencies at the Hanford Tank Farms
The Department of Energy (DOE) held an Enforcement Conference on August 29, 2006, with CH2M Hill Hanford Group (CHG) to discuss potential violations of nuclear safety requirements described in our Investigation Summary Report dated July 26, 2006. At that time, DOE elected to defer a decision on a potential quality improvement violation related to recurring radiological events and deficiencies in the identification and control of radiological hazards at the Tank Farms. This decision was based upon the fact that CHG senior management had initiated radiological work improvements but insufficient data was available to assess their effectiveness. On July 12, 2007, Office of Enforcement and DOE Office of River Protection personnel met with you and your staff to review the progress and effectiveness of these actions.
