About the project

The Canadian Nuclear Safety Commission (CNSC) is seeking comments from the public and Indigenous groups on the project description for the proposed Wheeler River Project. The project involves a new uranium mining and processing operation located in the Athabasca Basin in northern Saskatchewan, approximately 600 km north of the city of Saskatoon, 4 km west of Highway 914 and midway between Cameco Corporation’s Key Lake Mill and McArthur River Mine.

The CNSC has reviewed the project description and determined that it was written in accordance with the Prescribed Information for the Description of a Designated Project Regulations to the CEAA 2012. Detailed information about the project will be available in the environmental impact statement which will be submitted by Denison Mines Corporation at a later stage of the EA process (see next steps below).

Comments on the project description should be based on local, regional or traditional knowledge of the site or surrounding environment, or they should provide any other relevant information that may help with the conduct of the environmental assessment (EA). All comments received will be considered public.

Written comments must be submitted by June 30, 2019 to:

Marcelle Phaneuf, Environmental Assessment Officer
Canadian Nuclear Safety Commission
P. O. Box 1046, Station B
280 Slater Street
Ottawa, ON K1P 5S9
Telephone: 613-947-3209 or 1-800-668-5284
Fax: 613-995-5086

Next steps

After they receive the comments about the project description, CNSC staff will consider all submissions received and make recommendations that will inform the Commission’s decision on the scope of the factors to be considered in the EA. In addition, CNSC staff will respond to all comments received from members of the public and Indigenous groups. The comments and responses will be compiled in a table and publicly posted to the Canadian Environmental Assessment Registry. Efforts will be made to collate common issues.

Following the Commission’s decision on the scope of the EA, the proponent, Denison Mines Corporation, will be required to provide an environmental impact statement (EIS) to the CNSC for review. An EIS is a report written by a proponent that presents the technical studies and findings of an EA. The CNSC's Generic Guidelines for the Preparation of an Environmental Impact Statement Pursuant to the Canadian Environmental Assessment Act, 2012 provide general instructions on the preparation and information requirements that must be included in the EIS in order to comply with the requirements of the CEAA 2012.
