... , is briefly mentioned without references or a description; however, the addition of these references to the next version of the report would assist the stakeholders by providing a report with the necessary information for decision making. The committee understands and appreciates the challenges faced by DOE concerning Hanford tank integrity and the adoption of an active oversight, monitoring, and mitigation approach including historical measures such as dewatering tanks and installing asphalt water intrusion barriers in favor of focusing resources on getting on with cleanup sooner.

... Finding 5: The FFRDC made a defensible decision to refrain from attempting to estimate in qualitative or quantitative terms the likelihood of specific regulatory outcomes; however, the regulatory approval criterion section would be strengthened by including a more in-depth discussion on potential challenges that may need to be addressed in obtaining the necessary various regulatory approvals. Recommendation D: The FFRDC should include a discussion of issues associated with obtaining regulatory approval for the various options.

... Recommendation H: The FFRDC report should address the implications of using monthly averages of pretreated liquid SLAW compositions when dose limits are on a tanker-by-tanker basis. Finding 12: There appears to be an inconsistency between the dose rate limit at 3 meters having to be met by analyzing unshielded liquid waste and the statement that liquids will be transported in tanks that provide adequate shielding.

... providing more information surrounding the orphaned waste issue including specifics on how the issue might develop and what the consequences and coping measures might be. Finding 14: The committee found that options Grout 4B and Grout 6, especially 6, are intended to emphasize flexibility (multiple pathways)
