(Denison) for a new uranium mine near Russell Lake, Saskatchewan. In February 2019, Denison submitted a project description [1] for the Wheeler River Project (the project); a proposed new in situ recovery (ISR) uranium mining and processing operation to be located in the eastern Athabasca Basin in northern Saskatchewan. The scope of the proposed project would include underground and surface facilities to support the mining and processing of uranium ore using the ISR mining method, and producing up to 5400 tonnes of triuranium octoxide (U3O8) annually over a 20‒year operating period. Canadian Nuclear Safety Commission (CNSC) staff reviewed the Wheeler River Project description and confirmed that the project description is complete and in accordance with the Prescribed Information for the Description of a Designated Project Regulations under the Canadian Environmental Assessment Act, 2012 (CEAA 2012). CNSC staff also concluded that the project meets the definition of a “designated project” in the Regulations Designating Physical Activities (SOR/2012-147) and therefore requires an EA under CEAA 2012. As per the transition provision, section 182, of the Impact Assessment Act, 2019 (IAA 2019), the Wheeler River project commenced under CEAA 2012 and will continue to be completed under this legislation. This project is also subject to the EA requirements of the Government of Saskatchewan under The Environmental Assessment Act of Saskatchewan. Both the federal and provincial EAs will be coordinated to the extent possible. For example, only one environmental impact statement (EIS) will be produced to meet the needs of both EA processes. In addition, CNSC staff notified relevant federal authorities of the EA and requested information on their potential participation in the EA and/or interest in receiving further information. Indigenous communities identified as potentially having an interest in the project received a notice of the commencement of the EA and a copy of the project description for comment. CNSC staff also made the project description available on the Canadian Impact Assessment Registry website for a period of 30 days to seek public and Indigenous comments on the project in order to inform the conduct of the EA. The CNSC provided detailed responses to all comments received by members of the public and Indigenous groups. Both the comments and the responses were posted on the Canadian Impact Assessment Registry website and shared with all commenters. Future public and Indigenous participation opportunities for the project include the review of the draft EIS, EA report and Commission member documentation, as well as participation in the EA public hearing. Participant funding will be offered to facilitate this participation. e-Doc: 6005470 (WORD) - 1 - November 29, 2019 e-Doc: 6016260 (PDF) 19-H111 UNPROTECTED/ NON PROTÉGÉ All EAs under CEAA 2012 are required to consider certain factors listed under paragraphs 19(1)(a) to (h) of CEAA 2012, including the purpose of the project, alternative means of carrying out the project, environmental effects, the significance of these effects, and comments from the public and Indigenous peoples. Paragraph 19(1)(i) of CEAA 2012 also requires the Commission to consider any relevant regional study conducted by a committee established by the Minister of the Environment and Climate Change Canada. Under paragraph 19(1)(j), the Commission has the discretion of taking into account any other matter relevant to the EA that the CNSC, as the responsible authority, requires to be taken into account. Taking into account public and Indigenous comments and CNSC staff’s review of the project description, CNSC staff recommend to the Commission that the scope of factors to be considered include the factors mandated in paragraphs 19(1)(a) to (h) of CEAA 2012 and that no other factors be considered in this EA. Referenced documents in this CMD are available to the public upon request. e-Doc: 6005470 (WORD) - 2 - November 29, 2019 e-Doc: 6016260 (PDF) 19-H111 UNPROTECTED/ NON PROTÉGÉ SOMMAIRE L’objectif de ce document à l’intention des commissaires (CMD) est de demander à la Commission de déterminer la portée des éléments à examiner dans l’évaluation environnementale (EE) du projet Wheeler River de Denison Mines Corp. (ci-après Denison) concernant l’exploitation d’une nouvelle mine d’uranium près de Russell Lake, en Saskatchewan. En février 2019, Denison a présenté une description [1] du projet Wheeler River (ci-après le projet) : un projet d’extraction par récupération in situ et de traitement de l’uranium qui sera localisé dans la partie est du bassin Athabasca, dans le Nord de la Saskatchewan. La portée du projet englobe les infrastructures sous terre et en surface pour soutenir l’extraction et le traitement du minerai d’uranium au moyen de la méthode de récupération in situ,
