Accelerated Best Basis Inventory Baselining Task
The objectives of the Best Basis Inventory (BBI) baselining effort are to: (1) Provide inventories that are consistent with the revised BBI methodology and new BBI creation rules. (2) Split the total tank waste in each tank into six waste phases, as appropriate (Supernatant, saltcake solids, saltcake liquid, sludge solids, sludge liquid, and retained gas). (3) Identify sampling events that are to be used for calculating the BBIs. (4) Update waste volumes for subsequent reconciliation with the Hanlon (2000) waste tank summary. (5) Implement new waste type templates. (6) Include any sample data that might have been unintentionally omitted in the original BBI and remove any sample data that should not have been included. (7) Sample data to be used in the BBI must be available on TWINS. (8) Ensure that an inventory value is provided for each waste component. Sample based inventories for new supplemental BBI analytes are to be included when available. (9) Provide new means and confidence interval reports if one is not already available and include uncertainties in reporting inventory values.
