This panel plans to address the disposition of the more problematic US DOE and commercial/non-US DOE governmental waste streams. The panel will also focus on changes in mixed hazardous/radioactive waste requirements based upon revisions to US DOE Order 435.1, changes in US Title 10 Code of Federal Regulations Part 61 (10CFR61) along with any new requirements associated with the site-wide disposal contract. Accordingly, the panel will address selected institutional/regulatory topics including but not limited to: Removal of US EPA conservatively assigned Hazardous Waste Numbers (HWNs) and Allowances for blending/consolidating wastes. Impact from the WIPP shutdown and funding issues may also be discussed.
