Section Synopsis
Pages: 235-238The document provides a screening of potential impacts on migratory and Species at Risk (SAR) birds resulting from the Deep Geological Repository (DGR) project. It identifies 64 upland species, 3 shorebirds, 10 waterbirds, and 7 raptors within the project area, including several protected under the Migratory Birds Convention Act (MBCA) and the Species at Risk Act (SARA). The report outlines various pathways of change, such as habitat loss, sensory disturbance (noise, light, vibration), and chemical/radiological emissions. It concludes that while project activities could initially pose a moderate to high risk, the application of standard mitigation measures—such as seasonal clearing restrictions, buffer zones, and dust suppression—will reduce the residual effects to a negligible degree and an overall low risk level.
Community Assessment Narrative
The analysis exhibits a high degree of confidence in the efficacy of standard industry mitigation measures, often citing them as 'well-established' or 'routinely applied.' However, there is a notable analytical gap between the identification of 'moderate to high' potential adverse effects and the final 'negligible' risk rating. The document relies heavily on the assumption that birds will simply utilize adjacent habitats, without providing a carrying capacity analysis of those secondary sites. Furthermore, the use of the ALARA (As Low As Reasonably Achievable) principle for non-radiological stressors like noise and light is mentioned but not quantified with specific decibel or lumen thresholds. The conclusion of 'negligible' impact seems predicated on regulatory compliance rather than site-specific empirical modeling of bird population dynamics under chronic sensory stress.
Corrective Measures & Recommendations
1. Quantitative Stressor Modeling and Thresholds: The proponent must develop and disclose specific quantitative thresholds for noise and vibration during the construction and blasting phases. For example, noise levels should be modeled to ensure they do not exceed 60 dBA at the edge of identified sensitive habitats during the peak breeding season (May to August). This is necessary because 'negligible' is a qualitative term that lacks the precision required for rigorous environmental oversight. 2. Habitat Carrying Capacity and Displacement Study: A detailed study is required to verify the assumption that adjacent habitats can absorb displaced avian populations. This study should include multi-season surveys of 'alternative' sites to ensure they are not already at carrying capacity, which would otherwise lead to increased competition and reduced reproductive success for SAR species like the Canada Warbler or Olive-sided Flycatcher. 3. Detailed Adaptive Management Framework: The proponent should provide a 'Decision Tree' for adaptive management. For instance, if monitoring detects a 15% decline in SAR nesting success within the 500m buffer zone, specific corrective actions—such as the suspension of blasting or the installation of additional sound barriers—must be pre-defined and legally binding. 4. Long-term Cumulative Impact Assessment: Given the multi-decadal lifespan of the DGR project, the assessment must include a cumulative effects analysis that accounts for climate change-induced shifts in migratory patterns and other regional industrial developments. This ensures that the 'low risk' designation remains valid under changing environmental baselines and that the project does not contribute to a 'death by a thousand cuts' for regional biodiversity.
On 16 February, 2026 the Impact Assessment Agency of Canada (IAAC), with input from the Canadian Nuclear Safety Commission (CNSC), published a Summary of Issues (SOI) for the proposed Deep Geological Repository (DGR) for Canada’s Used Nuclear Fuel Project, put forward by the Nuclear Waste Management Organization (NWMO). The SOI identifies the key issues that IAAC considers relevant to the federal integrated impact assessment process for the project. NWMO’s response to the SOI will assist IAAC in determining whether an impact assessment is required under section 16 of the Impact Assessment Act. If an impact assessment is required, the issues outlined in the SOI—together with NWMO’s response—will help shape the scope of the assessment and inform the continued development and finalization of the Integrated Tailored Impact Statement Guidelines and associated plans.
Alignments to IAAC Summary (SOI)
The analysis of the proponent’s Initial Project Description (IPD) regarding migratory birds and Species at Risk (SAR) shows a high degree of alignment with the "Summary of Issues" (SOI) published by the IAAC on February 16, 2026. Specifically, Melgund Township’s concern regarding the lack of quantitative data on habitat loss directly supports the IAAC’s identified issue under the theme "Species at risk and their habitat," which notes a general concern regarding "insufficient information on species at risk and their habitats" and the need for more detail on "direct and indirect pathways of effects." While the proponent claims residual effects will be "negligible," the community’s finding that this rating lacks a scientific baseline due to missing acreage data validates the IAAC’s call for more information on the "levels of disturbance, displacement, or harm" listed under "Terrestrial Wildlife and their Habitat."
There is also strong alignment regarding the integration of Indigenous Traditional Knowledge (ITK). The community’s observation that ITK is insufficiently integrated into bird population assessments mirrors the IAAC’s broader requirement under "Indigenous Peoples - Consideration of Indigenous Knowledge," which flags concerns about how such knowledge is reflected in project planning and assessment. Melgund Township’s analysis goes a step further by identifying a specific technical gap: the proponent’s reliance on general industry experience rather than species-specific mitigation success rates. This supports the IAAC’s observation in Annex A (Project Description) regarding concerns over how the "effectiveness of proposed mitigation measures are characterized."
A notable discrepancy or "gap" identified by the community assessment is the proponent’s ambiguous use of the radiological term "ALARA" (As Low As Reasonably Achievable) to describe noise, vibration, and light mitigation for birds. While the IAAC SOI mentions "noise" and "light" under "Indigenous Peoples - Health effects," it does not explicitly flag the potential for ecological thresholds to be obscured by inappropriate radiological terminology. The community’s finding suggests that the IAAC’s general concern for "sensory disturbance" requires more specific ecological standards to be meaningful, as the current IPD language may prevent a true assessment of impacts on sensitive species like the Eastern Whip-poor-will.
Recommendations
The working group recommendations focus on moving from qualitative assertions to quantitative evidence. It is recommended that the proponent provide a comprehensive habitat loss assessment that details the exact hectares of wetlands and upland forests to be disturbed. This data is necessary to address the IAAC’s concern regarding "insufficient information" and to provide a verifiable baseline for the proponent’s "negligible" impact claims. Furthermore, the recommendation for a species-specific displacement analysis is essential to validate whether adjacent habitats can actually support displaced SAR, addressing the IAAC’s requirement to understand the "levels of displacement or harm" more clearly.
To ensure alignment with the IAAC’s focus on Indigenous rights and knowledge, the working group recommends the formal incorporation of ITK into bird monitoring and mitigation plans. This should specifically include using traditional observations to refine sensory disturbance buffers, rather than relying solely on the "ALARA" principle. Finally, to address the IAAC’s identified concerns regarding "Monitoring and institutional control," the proponent should establish a long-term monitoring framework with transparent "trigger" thresholds. These thresholds would ensure that adaptive management is not just a "best practice" commitment, but a mandatory response to specific ecological changes observed on the ground.
