... A section In the final environmental impact statement summary presenting the key findings and insights from the impact analysis would be helpful to the interested reader. For example, buried within the text of He DElS is the observation that He impacts are determined primarily by two variables: He Faction of wastes retrieved from the tanks and He degree of separations into Tow-activ~ty waste and high-level waste Factions.

... While such estimates can provide confidence that the actual impacts wail not exceed those presented In We DENS, they can significantly distort the comparisons among options. To avoid distortion of the comparisons, the final environmental impact statement should, to the extent possible, present expected values and ranges of risks for the quantitative impacts In addition to upper-bound estimates.

... Finally, as noted earlier in this report, because of the dynamic nature of decision making wad respect to Me management and remediation of Me tariff wastes, a review by Independent scientific and technical experts and an update of all the factors Mat are pertinent to Me decisions should be conducted approximately every 5 years, as allowed by 10 CFR Part 1021. Given He large scale of the Hanford Site environmental remediation, it is prudent to review costs, risks, and environmental impacts for environmental remediation of the entire Hanford Site, including the TWRS program, in a periodic public process.
