Transportation Risks: The Case for IA Inclusion

Executive Summary

The exclusion of off-site transportation from the formal Impact Assessment (IA) for the Revell Site Deep Geological Repository (DGR) has emerged as a primary point of contention among Indigenous Nations, regional stakeholders, and technical analysts. The proponent, the Nuclear Waste Management Organization (NWMO), characterizes transportation as an activity regulated separately by the Canadian Nuclear Safety Commission (CNSC) and therefore outside the scope of the Impact Assessment Act (IAA) [Analysis: Executive Summary – Description of the Project]. However, a forensic review of public testimony and technical gaps suggests this exclusion constitutes “project splitting,” which prevents a holistic evaluation of the project’s multi-generational risks. The movement of 5.9 million fuel bundles over 50 years along the Trans-Canada Highway (Highway 17) introduces significant environmental, safety, and socio-economic stressors that are inseparable from the repository’s operation [Comment Ref: 485].

Detailed Analysis

Regulatory Fragmentation and “Project Splitting”

The core argument for including transportation in the IA is that the DGR cannot function without a national transportation system; thus, it is an “incidental activity” under the IAA. Commenters argue that by decoupling the repository from the 1,700 km transit corridor, the proponent is artificially narrowing the project’s footprint to avoid federal scrutiny of the most high-risk phase [Comment Ref: 660]. Technical analysis confirms that this segmentation creates a “regulatory vacuum,” where the cumulative effects of thousands of shipments over five decades are never assessed as a single risk continuum [Analysis: 9. RELATED PROVISIONS IN THE PHYSICAL ACTIVITIES REGULATIONS].

Infrastructure and Highway 17 Vulnerabilities

The Revell Site is located directly along Highway 17, a critical national artery that is predominantly a two-lane road in Northwestern Ontario. Public testimony frequently refers to this stretch as the “Highway of Fears” due to high accident rates, frequent winter closures, and the presence of significant wildlife hazards like moose [Comment Ref: 258, 272]. The exclusion of transportation from the IA means that the specific risks of a radiological release during a transport accident—exacerbated by harsh northern climates and limited passing lanes—remain unstudied within the primary environmental review [Comment Ref: 218].

Indigenous Rights and Territorial Sovereignty

Indigenous Nations, including the Grand Council Treaty #3 (GCT3) and the Nishnawbe Aski Nation (NAN), assert that the transportation of high-level waste across their traditional territories engages Section 35 constitutional rights [Comment Ref: 705, 485]. They argue that the “chilling effect” of radioactive shipments through harvesting areas will impact their ability to exercise treaty rights, regardless of the technical safety of the casks [Comment Ref: 485]. By scoping out transportation, the proponent fails to facilitate Free, Prior, and Informed Consent (FPIC) for the numerous Nations situated along the transit routes [Comment Ref: 627].

Emergency Response Gaps in Unorganized Territories

The Revell Site and Melgund Township are located in unorganized territories that lack municipal infrastructure. Public comments from volunteer first responders highlight a critical lack of capacity, training, and equipment to manage a high-level nuclear incident [Comment Ref: 508, 242]. The current project description relies on conceptual emergency planning rather than an evidence-based analysis of the actual response capacity in remote areas along Highway 17 [Analysis: Executive Summary – Initial Screening of Potential Impacts of the Project].

Evidence from the Public Registry

• Grand Council Treaty #3: Argues that excluding transportation is contrary to the IAA and ignores adverse effects on Indigenous peoples within the transportation corridors [Comment Ref: 660].
• Nishnawbe Aski Nation (NAN): States that the transportation of 5.9 million bundles is an incidental activity that must be included to fulfill the Crown’s duty to consult [Comment Ref: 485].
• Mississaugas of Scugog Island First Nation: Highlights the risks of daily waste shipments over 1,700 km and the potential for “normal-operation” exposure along corridors [Comment Ref: 627].
• Local Residents: Express fear that a radiological accident could sever Highway 17, Canada’s only major east-west land artery, compromising national security and supply chains [Comment Ref: 242, 131].

Technical Deficiencies and Gaps

Internal technical reviews identify several critical omissions in the proponent’s handling of transportation:

• Lack of Corridor-Level Modeling: The proponent has not conducted site-specific modeling for atmospheric or hydrological dispersion of radionuclides along the Highway 17 corridor in the event of a transit breach [Analysis: 19.2.3.1 AIR QUALITY].
• Inadequate Testing Parameters: Critics point out that standard 9-meter drop tests for casks do not reflect the actual geography of the route, such as the 70-meter drop potential at the Nipigon River bridge [Comment Ref: 271].
• Climate Change Resilience: The project description fails to integrate how evolving climate conditions (e.g., increased freezing rain, forest fires) will affect the reliability of the transportation infrastructure over 50 years [Analysis: 11. Anticipated Schedule].

Recommendations and Mandates

To rectify these deficiencies, we provide the following detailed recommendations for the proponent:

• Strongly recommend the inclusion of the entire transportation corridor from reactor sites to the Revell Site as a core Valued Component (VC) within the Impact Statement. This must include a comprehensive risk assessment of all road and rail routes.
• Strongly recommend a “Service Capacity Stress Test” for all emergency response units along the Highway 17 corridor. The proponent should demonstrate 100% self-sufficiency for radiological emergency response in unorganized territories, rather than relying on local volunteer fire departments.
• Strongly recommend the development of a “Stigma and Perceived Risk” impact study. This study should quantify how the presence of a nuclear transportation corridor affects property values, tourism, and Indigenous land use in Melgund Township and surrounding areas.
• Strongly recommend a detailed comparative analysis of rail versus road transport, including a full greenhouse gas (GHG) lifecycle assessment for the 50-year transportation phase.

Conclusion

The exclusion of transportation from the Revell Site DGR Impact Assessment is a significant regulatory and social failure. It fragments the project’s risk profile, disenfranchises corridor communities, and ignores the physical realities of the Trans-Canada Highway. For the assessment to be considered credible and to uphold the Honour of the Crown, the proponent must bring the full logistical lifecycle of the waste into the formal IA scope. Failure to do so leaves the project vulnerable to sustained opposition and legal challenges regarding the adequacy of the consultation process.
