U.S. EPA Superfund Remedial Program's Approach for Addressing Radioactive Contamination
Archived: Wednesday, April 17, 2024
Sponsored by: U.S. EPA OLEM OSRTI ARD Science Policy Branch
The U.S. Environmental Protection Agency (EPA) Superfund program has developed regulations and guidance for remediating radioactively contaminated CERCLA sites. The focus of this presentation is an overview of EPA's recommended guidance documents on ARARs and risk assessment, models for conducting risk and dose assessments, and community involvement tools for engaging in meaningful involvement with the public that are intended to be used during the process to determine cleanup levels for radioactively contaminated Superfund sites. The presentation is intended to help the audience obtain knowledge of EPA's recommended guidance to facilitate cleanups that are consistent with how chemical contaminants are addressed, except where technical differences posed by radiation are addressed. The guidance and tools that are discussed in the presentation are freely available on the internet. This webinar provides an updated version of Module 3 that was presented in the ITRC webinar "Radiation Site Cleanup: CERCLA Requirements and Guidance" on June 5, 2007.

Stuart Walker has been employed by U.S. EPA in Washington, DC since 1990 in either the Superfund program (the Office of Superfund Remediation and Technology Innovation) or the Office of Radiation and Indoor Air working on issues regarding the cleanup of contaminated sites. His primary area of responsibility includes serving as the Superfund program's national lead on issues regarding radioactively contaminated CERCLA sites. In this role, Stuart develops national policy for risk assessment including models, community involvement, compliance with Applicable or Relevant and Appropriate requirements (ARARs), establishing cleanup levels and management of radioactive contamination at CERCLA sites.
