[en] This report discusses the treatment of mercury contaminated wastes in the Waste Receiving and Processing (WRAP) Facility Module 2A. It specifically relates to waste streams 5A1, 5A2, and 5A3, which have been proposed for treatment in the WRAP 2A Special Waste Processing Area. Based on changes in projected mixed waste generation rate, and increased understanding of the nature of the mercury contaminated wastes intended for treatment in WRAP 2A, justification for deleting the mercury roast/retort process from WRAP 2A is provided. A recommendation has been made to redesignate and dispose of stored fluorescent light tube waste as non-hazardous. If this recommendation is followed, historical documentation suggests that approximately 1.6 drum-equivalents of the remaining stored mixed wastes may contain high concentrations of mercury. If this information is verified, and some of these wastes do indeed contain mercury in concentrations above 260 parts per million, it is recommended that a Petition for Equivalent Treatment Method be pursued rather than treating these wastes by roast/retort. Recommendations are provided for revision to project documentation, and additional information is provided to assist design efforts for treatment of these wastes in WRAP 2A
