Environment & Safety
Setting A New Safety Standard
In June, 2021 our Blind River Refinery celebrated the remarkable achievement of operating for 15 years without a lost-time injury. The safety culture that exists at the Refinery is a reflection of the commitment of every employee to put safety first – for themselves and for those around them.
Since 1990, Blind River has received Cameco's top award for safety performance, the Mary-Jean Mitchell Green Award, more times than any other Cameco facility.
Safety
We manage the safety of our workers through programs, systems, and standards, with our Safety, Health, Environment and Quality (SHEQ) Policy providing overarching guidance. There are many aspects of the management system that contribute to a safe work environment, a few examples include:
- Risk assessments help identify issues and determine the appropriate controls; the corrective action process verifies that incidents and near misses are reported, tracked, investigated and shared with colleagues; and emergency preparedness and planning prepare us to respond to serious incidents.
- We have developed 12 corporate safety standards to help protect our workers from our most common hazards. Some standards guide our general safety practices, such as our job hazard analysis and our job task observation, and other standards deal with specific hazardous situations (similar to other companies’ life saving rules): such as fall protection, confined space entry, rigging and hoisting, and control of hazardous energy (also referred to as lockout/tagout).
- Routine audits are conducted to monitor compliance with regulations and our own requirements. These and other aspects of the management system are routinely examined to verify that they continue to be effective at keeping our workers safe.
Radiation Protection
Radiation risks are effectively managed at Blind River through a formal radiation protection program and dedicated personnel who ensure that workers are safe. The program ensures that radiation protection is considered in the physical design of all facilities and operating procedures. It also provides for systematic monitoring of radiation in work areas and tracking the exposures of individual workers using a combination of monitoring devices and health testing. Radiation exposures at Blind River are far below regulatory limits.
Environmental Protection
At Cameco, protection of the environment is one of our highest corporate priorities during all stages of our activities, from exploration through development, operations, decommissioning, and reclamation.
We monitor our performance by tracking corporate and site-specific key performance indicators, conducting environmental monitoring programs, and regularly auditing our adherence to the requirements of these programs We use the information from all of our programs to help us to identify opportunities to improve.
Environmental management system
We have a ISO 14001-certified environmental management system used across our operating sites, which is supported by a corporate Environmental Management Program that outlines the operating requirements sites must meet. Our environmental management system encourages and promotes continuous adaptation of our practices based on new information and technologies.
Environmental risk assessments
We complete environmental risk assessments to systematically identify, quantify, and to characterize the potential risks to the environment, workers, and the public. We use our environmental risk assessments to inform our decisions and actions. Additionally, we complete an iterative process, where required, to verify that our proposed measures to protect the environment and the public are effective. We review or update the assessments every five years, incorporating results from our environmental monitoring programs and other scientific advances.
Corrective action process
We have a corrective action process in place to systematically investigate and address the causes of non-conformance to regulatory requirements or internal standards. The process includes classifying the non-conformance, assigning the appropriate level of investigation (dependent on incident significance), and tracking the recommended corrective actions to prevent and mitigate similar occurrences.
Audits
To support our culture of continuous improvement, our processes and operations undergo regular audits, including:
- Our environmental management system is audited by a third-party every three years as a requirement to maintain our ISO 14001 certification.
- Our SHEQ team conducts an internal audit of our SHEQ programs on a three-year cycle. The total audit scope is split in half and executed on a rotating basis. This means that all our sites undergo at least two audits to cover all aspects of our SHEQ programs within every three-year period. The audit follows the ISO 19001 process and encompasses our environmental and safety programs.
- We also maintain and implement an internal audit program at our corporate office. Results and recommendations from this systematic and documented process are presented to senior management, who are responsible for implementing them and correcting any deficiencies. The internal audit group reports to the audit and finance committee of the board.

| Incident Date | July 1, 2024 |
| Incident | Reportable Leak & Discharge |
| Details | On June 26, 2024, when the glycol heating systems were drained for maintenance, a mechanical failure occurred. It was observed that the drain valve on number three coil was leaking glycol. A pipe cap was immediately installed to stop the leak. It was assumed the leak had been minimal and there was minimal glycol in the system since the coil had been isolated and drained in 2023 when it had failed. During a maintenance inspection, it was determined that glycol had passed through the sewage plant and was released to Lake Huron on July 1, 2024. A lab investigation estimates 70L of glycol had spilled. There was no health or safety risk posed to the public, workers, or the environment by this release. |
| Corrective Action | An investigation is currently underway by Cameco to prevent future occurrences. The Canadian Nuclear Safety Commission, Town of Blind River and the Ministry of Environment, and Conservation and Parks have been notified. |
