The Shattuck Superfund site under EPA Region 8 jurisdiction contained several Operable Units,<br />
including OU-8 that was contaminated with Radium. The EPA implemented a ROD in 1992 that<br />
called for containment of the radioactive material in an onsite monolith. A five year review found<br />
Radium leaving the site. A ROD Amendment was initiated in 2000 that called for the excavation<br />
and offsite disposal of the radioactive material 5 . The EPA goes on to acknowledge that<br />
“Although all of the alternatives would protect human health and the environment in the<br />
short-term, only Alternative 3 which calls for the removal of the waste from the site to an<br />
approved disposal facility can ensure long-term protectiveness 6 .” EPA Region 8 eventually<br />
determined that a decision reducing the Operation & Maintenance and reliance on institutional<br />
controls would result in the greatest overall protectiveness.<br />
