[en] Work was carried out with extensive involvement of technical and policy people from the western state governments through the creation of a High-Level Radioactive Waste Committee of the Western Interstate Energy Board. Committee members, who are from governor's offices and state agencies, have committed themselves to developing a thorough technical understanding of the issues so that they can have confidence in the analyses performed by others. The Committee closely directed and contributed to the preparation of work products by the WIEB staff. Activities under the contract were conducted over a 31-month period, during which time the specific tasks were modified and expanded to reflect the needs and interests of the Department of Energy and the HLW Committee
