Step 3: Phase 2 - Field Studies and Engagement

In 2015, the NWMO began working with communities in this area to plan field studies and engagement as part of Preliminary Assessment (Step 3: Phase 2). Through fieldwork, more detailed studies and broadened engagement, Phase 2 assessments expand upon work completed in Phase 1.

Based on findings from initial field studies, we may conclude studies in areas with lower potential to meet technical and community well-being requirements.

We will then work with communities in areas that continue in the process to plan more intensive field studies.

As studies are completed, we will publish the details here.

Planning Initial Borehole Drilling and Testing

The focus of early geoscientific studies in Central Huron is to determine if the rock in the area has the potential to satisfy our safety requirements for a deep geological repository for the long-term management of Canada’s used nuclear fuel.

Geoscientific studies conducted to date have involved desktop studies, which make use of publicly available information about the geology of the area. A next step in the process involves drilling one initial borehole in Central Huron to further understand the general geology of the community. This initial borehole may be drilled on municipal land.

The NWMO is working together with people in the area to begin to identify location, scope and timing of this initial borehole drilling.

If the findings from drilling and testing of an initial borehole provide additional confidence in the geology across the community, the next phase of work could involve additional borehole drilling and testing focused at a preferred potential repository site. Before we could proceed, we would need to work together with people in the area to develop a process for considering and securing land for that future borehole drilling and testing since private land may be involved.
