The Defense Nuclear Facilities Safety Board (DNFSB) has advised the Department of Energy (DOE) to concentrate the near-term sampling and analysis activities on identification and resolution of safety issues. The data quality objective (DQO) process was chosen as a tool to be used to identify the sampling and analytical needs for the resolution of safety issues. As a result, a revision in the Federal Facility Agreement and Consent Order (Tri-Party Agreement) milestone M-44 has been made, which states that ``A Tank Characterization Plan (TCP) will be developed for each double-shell tank (DST) and single-shell tank (SST) using the DQO process``. This document satisfies that requirement for Tank 241-BX-109 (BX-109) sampling activities. Tank BX-109 is identified as a low-heat load tank, is passively ventilated, and is classified as sound with respect to tank integrity. The tanks as interim stabilized in September 1990 and partial interim isolation has been completed. As of January 1995, approximately 730 kL (193 kgal) of sludge was contained in the tank; of which 49 kL (13 kgal) was drainable interstitial liquid. Single-shell Tank BX-109 was constructed as a first generation type 2 tank between 1946 and 1947 and is located in the 200 East Area. Tank BX-109 is expected to have one primary layer. A sludge layer composed of first-cycle waste and uranium recovery waste. An estimated inventory based on historical sample and analysis data is shown in a table.
