-Screen out sites that should be removing contamination to achieve unrestricted release*A site would be eligible if "- further reductions in residualradioactivitynecessarytocomplywiththe residual radioactivity necessary to comply with the provisions of 20.1402 -would result in net public or environmental harm or

-were not being made because the residual levels associated with restricted conditions are ALARA."

ELIGIBILITY (CONT.)*Commissions' Orders regarding Shieldalloy

-Series of Shieldalloylawsuits with associated Court and Commission actions-Explain original meaning of provision and clarifies the analysis is limitedtofurtherremovalofresidualradioactivity limited to further removal of residual radioactivity-Not a comparison of individual doses of restricted and unrestricted release and selection of the lowest dose-Cost benefit analyses following NUREG-1757, Appendix N *Costs/benefits of further removal of residual radioactive material from levels proposed to remain onsite to the unrestricted release level *Net public harm analysis (costs of harm to people and environment compared to benefits, e.g., collective dose averted dollar value)ALARA(totalcostscomparedtobenefitsegcollectiedoseaerted

-A dverse natural p rocesses (e.g., erosion

• Asystemofcontrolstoensuresafety A system of controls to ensure safety-25 mrem/yrwith restrictions -Legally enforceable and durable ICs -EBs designed for site

-Monitoring and maintenance; 5-year rechecks

-Independent third party/government backup to site owner/custodian

-Financialassuranceforthirdparty Financial assurance for third party-Dose "caps" if ICs fail: "safety net"

-Remain licensed, if needed 14
