Project Specifics

As Japan progresses with nuclear decommissioning, there is a recognized need to establish clear end states for its sites. Longenecker & Associates, a Geosyntec Company, was commissioned to use our international experience with decommissioning, along with our knowledge of best practices, to document processes and methods used in the United States Department of Energy (US DOE) cleanup program for negotiating site end states. We conducted a comprehensive review of the regulatory frameworks, agencies, and agreements that shaped these decisions. Our focus was on five US DOE sites: Rocky Flats, Mound, Idaho National Laboratory, Oak Ridge East-Tennessee Technology Park, and Hanford. Each site represented varying phases of end-state negotiation and development.

Geosyntec Scope of Services

We synthesized the complex history and practical application of end-state negotiation within the US DOE’s nuclear cleanup program and put it in the context of Japan’s developing cleanup requirements and regulatory framework.

To do this, we explored the following key questions:

• How are end states defined and negotiated in the US context, particularly at sites with complex chemical and radiological contamination?
• What are the key regulatory frameworks, agencies, and agreements involved, and how do they interact?
• What are the practical applications of these processes across a range of US DOE sites with different characteristics and cleanup phases?
• Most importantly, what best practices and lessons learned from the US experience could be directly applied to the development of an end-state structure/framework for Japan, especially given the inherent complexities and long-term implications of such a challenging cleanup effort?

Our practitioners undertook a three-phased approach to address the objectives, focusing on US DOE sites:

• Research and Documentation: We conducted a comprehensive review of the regulatory frameworks governing US DOE cleanup, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA), Uranium Mill Tailings Remedial Action (UMTRA), the Formerly Utilized Sites Remedial Action Program (FUSRAP), and the National Environmental Policy Act (NEPA).
• Detailed Case Studies: We selected five diverse US DOE sites to demonstrate the practical application of the decision-making processes in real-life examples.
• Recommendations for Japan: Based on the findings from the regulatory framework analysis and case studies, we identified good practices relevant to the Japanese decommissioning program. We outlined necessary enabling actions, identified involved organizations, and explained expected outcomes and benefits.

Notable Accomplishments

Our work provided invaluable insights and clear recommendations for Japan’s decommissioning efforts:

• Comprehensive US End-State Overview: This element provided a robust foundational understanding for Japanese stakeholders.
• Clearly Defined Regulatory Frameworks: This element emphasized that regulatory agreements precisely defining roles, responsibilities, cleanup levels, end state decisions, milestones, collaboration expectations, and dispute-resolution mechanisms are a necessity for successful decommissioning.
• Early and Community-Involved Future Land-Use and End-State Decisions: This element highlighted the importance of defining the end state early in the cleanup process. We emphasized that involving the local community is key to gaining clarity, maintaining focused outcomes, and addressing regulatory compliance, cleanup achievability, and community agreement on final land use.
• Proactive Stakeholder Engagement: This element emphasized the importance of identifying and involving all potential stakeholders early and often in the decision-making process, recommending stakeholder mapping as an effective method to visualize influence and connections.
• Strategic Contract Approach: This element demonstrated that contracting models significantly impact successful site closure, pointing to the success of cost-plus incentive fee contracts.
• Actionable Insights for Japanese Stakeholders: Finally, we provided practical advice on how to apply these lessons, helping Japanese regulatory authorities and organizations make informed decisions for defining end states at their nuclear sites.
