Draft Section 3.7<br />

Issue<br />

378<br />

ALTERNATIVE DISPOSAL CONCEPTS<br />

Ice Sheet Disposal unacceptable because <strong>of</strong> the possible interactions between waste,<br />

ice sheets and weather variations. (88, 121)<br />

Response<br />

The ice sheet disposal concept is not considered a preferred alternative for the dis-<br />

posal <strong>of</strong> radioactive waste. One reason is that there are significant environmental impact<br />

uncertainties associated with this concept. Section 6.1.5.3 <strong>of</strong> the final Statement ad-<br />

dresses the areas <strong>of</strong> uncertainty. Section 6.2 presents a comparison <strong>of</strong> alternatives that<br />

further discusses the importance <strong>of</strong> these uncertainties.<br />

Draft Section 3.7<br />

Issue<br />

Ice Sheet disposal - This entire section should be rewritten. Additional data from<br />

the Dry Valley Drilling Project, and the Ross Ice Shelf Project provide significant<br />

additional geologic scenario. (43)<br />

Response<br />

Alternate concept sections presented in the draft Statement have been significantly<br />

revised for the final Statement (see Chapter 6.0). The final Statement presents environ-<br />

mental and other information believed to be sufficient for comparison <strong>of</strong> the alternatives.<br />

Draft Section 3.7<br />

Issue<br />

The general overall caution and concern voiced in this section about using the ice<br />

sheet method is concurred with. This section (3.7) is better presented than 3.6 or 3.5<br />

because it treats the uncertainties in a clearer fashion. (124)<br />

Response<br />

In the preparation <strong>of</strong> Section 6.1 <strong>of</strong> the final Statement effort was made to present<br />

the concepts in an equivalent and more comparable manner. However, complete equivalence <strong>of</strong><br />

presentation was not possible because <strong>of</strong> the underdeveloped status <strong>of</strong> many <strong>of</strong> the concepts.
