ALTERNATIVE DISPOSAL CONCEPTS<br />

How can this dismissal <strong>of</strong> the problems <strong>of</strong> isolation for these concepts be rationalized<br />

with the 50 or more pages <strong>of</strong> detailed consideration given to these possibilities in Sec-<br />

tion 3.1? The Final EIS could apply this assessment to geologic disposal, but undoubtedly<br />

will not. In which event it should recognize that these concepts are as susceptible to<br />

intrusion as conventional geologic disposal - or more so. (154)<br />

Response<br />

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

balance in the discussion <strong>of</strong> alternative concepts. However, in many cases because <strong>of</strong> the<br />

relatively undeveloped nature <strong>of</strong> the alternatives the information presented cannot reflect<br />

the breadth and depth <strong>of</strong> consideration given to the mined geologic repository. Section 6.2<br />

<strong>of</strong> the fi'nal Statement takes this into consideration in the presentation <strong>of</strong> comparisons <strong>of</strong><br />

the alternatives and the mined geologic repository.<br />

The failure to distinguish between the concepts <strong>of</strong> containment and isolation (as we<br />

define them) is endemic to the entire Draft EIS but is more rampant than in these four<br />

pages. The two subsections labeled "Isolation" start with two and three bullets, respec-<br />

tively, which speak to the containment <strong>of</strong> waste. There then follows in each subsection the<br />

following statement:<br />

Response<br />

"isolation formation unlikely to be susceptible to breaching the natural events<br />

(tectonism, volcanism, meteorite impact) or man-made events (resource investiga-<br />

tion or exploitation, surface or subsurface activities, acts <strong>of</strong> war or<br />

sabotage)." (154)<br />

Please refer to the Glossary in Chapter 8.0 <strong>of</strong> the final Statement.<br />

Candidate Geologic Environments: Effects <strong>of</strong> local stresses and conditions -- such as<br />

varying topographic load and joint patterns -- on uplift resulting from reverse well injec-<br />

tion should be further examined in the course <strong>of</strong> testing suitable monitoring methods that<br />

would not penetrate the individual waste sheets. (218-DOI)
