Using EPA's Risk Assessment Tools for Superfund When Addressing Removal Actions and Late-Phase Response to Terrorist Attacks - 18228

EPA's Office of Superfund Remediation and Technology Innovation (OSRTI) has three internet based calculators, or risk assessment models, for developing risk based Preliminary Remediation Goals (PRGs) for radioactively contaminated CERCLA sites. These PRG calculators are EPA's recommended methodology for developing risk-based concentrations for remedial actions for soil and water (PRG), inside buildings (BPRG), and outside hard surfaces (SPRG). EPA has three equivalent calculators for dose assessment, which are the Dose Compliance Concentration (DCC) calculator for soil and water, inside buildings (BDCC), and outside hard surfaces (SDCC). The three PRG calculators also include default PRG tables provided for each of the calculators showing concentrations corresponding to 1 x 10-6 when the calculators are run using all of their default parameters. This presentation will provide information on how users may employ these tools beyond their original intended uses in the remedial program, to develop risk based cleanup levels during the late-phase portion of an actual response after a Radiological Dispersal Device (RDD) or Improvised Nuclear Device (IND) terrorist attack or a major accident at a Nuclear Power Plant (NPP), or a simulation during an exercise of an RDD/IND/NPP event, they may want to run the calculator using more site-specific data. This presentation will provide information on how users may employ these tools beyond their original intended uses in the remedial program, and focus on some of the more conservative default parameters that are likely candidates for replacement by site-specific information.
