The activities conducted at the Beaverlodge properties are overseen by the Joint Regulatory Group, which consists of Saskatchewan Ministry of Environment (SMOE), Canadian Nuclear Safety Commission (CNSC), Environment and Climate Change Canada, and the Department of Fisheries and Oceans.

More formally, the Beaverlodge properties are regulated by the CNSC in accordance with the federal Nuclear Safety and Control Act and regulations, as well as SMOE in accordance with provincial laws and regulations for the protection of people and the environment. Both regulators conduct regular site inspections and audits to verify that people and the environment are protected.

The CNSC renewed the licence for the Beaverlodge decommissioned properties for a 24-month term in 2023 to provide additional time to prepare the final set of properties for release from CNSC licensing and transfer to the Province of Saskatchewan's Institutional Control Program (IC Program). As part of this preparation, Cameco developed a Long-Term Monitoring Program that will be implemented by the Saskatchewan Ministry of Energy and Resources under the IC Program.

Before decommissioned properties can be accepted into the provincial IC Program, they must be released from federal CNSC licence. The goal of managing the decommissioned Beaverlodge properties has been to ensure the properties and areas downstream are meeting the objectives of being physically and radiologically safe, secure, and stable as outlined with the overarching Performance Objectives:

• Safe – The site is safe for unrestricted public access. This objective is to ensure that long-term safety is maintained.
• Secure – There must be confidence that long-term risks to public health and safety have been assessed by qualified people and are acceptable.
• Stable/Improving – Environmental conditions (e.g., water quality) on and downstream of the decommissioned properties are stable and continue to naturally recover as predicted.

To determine if a site is meeting the performance objectives, site specific performance indicators were established (Figure below). The applicable indicators vary depending on the nature of the property, but generally include:

• ensuring that risks associated with residual gamma radiation and crown pillars are acceptable;
• mine openings to surface are closed and secure;
• boreholes (if present) are plugged; and
• historical mining debris has been removed.

The stable/improving objective is also related to these performance indicators, but is more relevant to monitoring water quality. In order to verify that conditions on and downstream of the properties are stable/improving, Cameco has continued to monitor the progress of natural recovery and the expected localized improvements from the additional remedial measures implemented at the properties. Meeting these objectives will ensure human health and ecological risk are managed to acceptable levels to allow for a release from licensing.

The release of the Beaverlodge properties from CNSC licensing into the IC Program has been a gradual process, beginning with the first five properties in 2009. Twenty more properties were released from CNSC licensing in 2019, with 19 properties transferred to the IC Program and one property free-released. In 2022, an additional 18 properties were released from CNSC licensing and were transferred to the IC Program.
