This Waste Characterization Data and Technology Development Needs Assessment provides a framework for summarizing needs and technology development information. The work was funded and developed for use by the " Underground Storage Tank Integrated Demonstration (UST-ID) and was produced jointly by Pacific Northwest Laboratory (the Technology Policy Analysis and-Waste Technology Centers) and Westinghouse Hanford Company (the Systems Engineering Group). lt was reviewed by technical experts from the Hanford Site and Ames Laboratory at lowa State University representing both the U.S. Department of Energy (DOE) Office of Technology Development (EM-50) and the Office of Waste Operations (EM-30). The ultimate objectives of this effort were to structure the characterization technology development funding problem, using a general framework, and to summarize currently available needs data to support immediate funding decisions. Those data can be updated to support future funding cycles. The report does not prioritize or recommend specific technology developments. Rather, given high levels of uncertainty surrounding underground storage tank (UST) characterization needs and the fast-changing remediation environment, it identifies • "reliable" (e.g., relatively well substantiated) characterization data needs • the most promising technologies for addressing these needs. Evaluation criteria and procedures for prioritizing and integrating those responses into coherent funding packages are described in a separate report. (a) (a) Quadrel, M. J.
