The Department of Energy issued a preliminary notice of violation (PNOV) to Bechtel BWXT Idaho LLC, which operates the Idaho National Engineering Environmental Laboratory (INEEL), for violations of rules and procedures during drum venting activities at the Radioactive Waste Management Complex and a breakdown in work procedures during a cooling change-over at the Advanced Test Reactor. The drum venting event resulted in a proposed civil penalty of $41,250. None of the November 2001 violations resulted in injuries or releases of radioactive or hazardous materials.
