the remoteness <strong>of</strong> the disposal site and the major operational and equipment requirements that<br />

would have to be satisfied for retrieval. Physical protection <strong>of</strong> the sensitive facil-<br />

ities and transportation operations would be the most effective way to deny access to the<br />

waste for the short term, as is common to most waste disposal concepts. See Section 4.10 for<br />

additional discussion <strong>of</strong> predisposal operations safeguards requirements.
