Effective December 1, 2003, the U.S. Congress directed the Department of Energy (DOE) to file a permit modification request with the New Mexico Environment Department (NMED) to amend the Hazardous Waste Facility Permit (hereinafter 'the Permit') at the Waste Isolation Pilot Plant (WIPP). This legislation, Section 311 of the 2004 Energy and Water Development Appropriations Act, was designed to increase efficiencies in Transuranic (TRU) waste characterization processes by focusing on only those activities necessary to characterize waste streams, while continuing to protect human health and the environment. Congressionally prescribed changes would impact DOE generator site waste characterization programs and waste disposal operations at WIPP. With this legislative impetus, in early 2004 the DOE and Washington TRU Solutions (WTS), co-permittee under the Permit, submitted a permit modification request to the NMED pursuant to Section 311. After a lengthy process, including extensive public and other stakeholder input, the NMED granted the Permittees' request in October 2006, as part of a modification authorizing disposal of Remote-Handled (RH) TRU waste at WIPP. In conclusion: Implementation of the Permit under the revised Section 311 provisions is still in its early stages. Data are limited, as noted above. In view of these limited data and fluctuations in waste feed due to varying factors, at the current time it is difficult to determine with accuracy the impacts of Section 311 on the costs of characterizing TRU waste. It is safe to say, however, that the there have been many positive impacts flowing from Section 311. The generator sites now have more flexibility in characterizing waste. Also, RH TRU waste is now being disposed at WIPP - which was not possible before the 2006 Permit modification. As previously noted, the RH modification was approved at the same time as the Section 311 modification. Had the Section 311 changes not been implemented, RH TRU waste may not have been successfully permitted for disposal at WIPP. Changes made pursuant to Section 311 helped to facilitate approval of the proposed RH TRU modifications. For example, the three scenarios for use in AK Sufficiency Determination Requests, described herein, are essential to securing approval of some RH TRU waste streams for eventual disposal at WIPP. Thus, even if characterization rates do not increase significantly, options for disposal of RH TRU waste, which may not have been possible without Section 311, are now available and the TRU waste disposal mission is being accomplished as mandated by Congress in the LWA. Also, with the Section 311 modification, the Permittees commenced room-based VOC monitoring in the WIPP repository, which is also a positive impact of Section 311. Permit changes pursuant to Section 311 were a good beginning, but much more is need to encourage more efficient methodologies in waste characterization activities for TRU mixed waste destined for WIPP. Although the Permittees now have more flexibility in characterizing waste for disposal at WIPP, the processes are still lengthy, cumbersome, and paper-intensive. As the generator sites continue to characterize waste under Section 311, more data will likely be compiled and evaluated to assess the longer term cost and technical impacts of Section 311. Also, further refinements in TRU waste characterization requirements through Permit modifications are likely in future years to eliminate, improve, and clarify remaining unnecessary and redundant Permit provisions. Continuous improvements to the TRU waste characterization program are bound to occur, resulting in even greater efficiencies in the characterization and ultimate disposal of TRU waste. (authors)
