Environmental protection reviews under the Nuclear Safety and Control Act

The CNSC conducts environmental protection reviews (EPRs) for all licence applications with potential environmental interactions, in accordance with its mandate under the Nuclear Safety and Control Act (NSCA), to ensure the protection of the environment and the health of persons. An EPR is a science-based environmental technical assessment by CNSC staff as set out in the NSCA. An EPR under the NSCA (formerly known as an EA (environmental assessment) under the NSCA) is conducted for projects not listed in the Physical Activities Regulations or for projects previously assessed through an environmental assessment (either under CEAA 2012 or its predecessor CEAA 1992).

An EPR under the NSCA is primarily based on information that the applicant or licensee is required to submit to the CNSC through the established licensing process, such as the licence application and its supporting documentation, and information on environmental protection measures. An EPR under the NSCA is also based on compliance and technical assessment activities completed by CNSC staff (e.g., reviews of annual environmental monitoring reports and environmental risk assessments). An EPR under the NSCA may also be supported by independent verification activities such as the CNSC’s independent environmental monitoring program (IEMP), as well as relevant regional health studies, monitoring programs and Indigenous knowledge studies.

The purpose of an EPR is to report the outcome of CNSC staff’s review of licensing and environmental compliance activities conducted under the NSCA. This review serves to assess whether the applicant or licensee will, in carrying out a licensed activity, make adequate provisions to protect the environment and health and safety of persons.

Here is a list of completed EPRs under the NSCA reports with links to their executive summaries. To obtain the full copy of the EPR report, contact us at cnsc.ea-ee.ccsn@canada.ca, or call 613-995-5894 or 1-800-668-5284 (in Canada). Please provide the name of the facility with your request.
