- lost-time incidents for workers
- environmental monitoring results
- environmental reportable spills and corrective actions taken

- In 2016, AREVA Resources Canada Inc. (now Orano Canada) requested an increase to their annual authorized production rate of uranium (U3O8) concentrate at their McClean Lake Mill site. AREVA submitted a request to the CNSC to increase the production from 13 to 24 Mlbs per year. After a thorough review, the CNSC has determined that the proposed increase will not have an unreasonable effect on the health and safety of workers or the environment. The CNSC authorized AREVA to proceed with the production increase.
As part of CNSC's regulatory requirements, major licensees must have robust public information and disclosure programs in place. These programs include a disclosure protocol developed in consultation with community stakeholders.
