Type: Screening
FEAI reference number: 19651

Project Description
The Canadian Nuclear Safety Commission (CNSC) has received notice from COGEMA Resources Inc. and Cameco Corporation of their intent to apply for authorization for the handling, transport and disposal of Cigar Lake waste rock in the McClean Lake Operation's Sue C pit in northern Saskatchewan.
The Cigar Lake and the McClean Lake Operations are located near the eastern edge of the Athabasca Basin in northern Saskatchewan. Cigar Lake, currently an underground test mine, is located 660 km via air north of Saskatoon. McClean Lake, a producing uranium mining and milling facility, is located 700 km via air north of Saskatoon. The two sites are approximately 70 km apart by existing roads.
Before the CNSC makes its decision on the application, an environmental assessment must be completed in compliance with the Canadian Environmental Assessment Act. The purpose of an environmental assessment is to identify the possible environmental effects of a proposed project, and to determine whether these effects can be mitigated before the project is allowed to proceed.
The environmental assessment process on this project began in October 1999, and has since included extensive public consultation. Presentations and discussion sessions were held with key target groups, such as the Athabasca Environmental Quality Committee, the Athabasca Working Group, and the Athabasca Economic Development and Training Corporation. Project-related information was broadly distributed through publications in the Athabasca communities. A public meeting was also held with interested stakeholders in Saskatoon. As well, regular discussions with regulatory agencies were held.
The Environmental Assessment (EA) Screening Report will be made available to the public on May 9, 2003, and a commission hearing will be held on June 25, 2003, to consider the EA Screening Report. In order for the project to move forward, amendments to Cigar Lake's excavating licence and McClean Lake's operating licence will be required; the Commission will hold public hearings to make decisions on the licence amendments at a later date. Cameco Corporation and COGEMA Resources Inc. have advised the CNSC that they do not plan to transport waste rock to McClean Lake's Sue C pit until the year 2019. COGEMA Resources Inc. has advised the CNSC that it will apply for amendments to McClean Lake's operating licence to include Cigar Lake waste rock disposal in a few years when they apply for other amendments.
Steps Ahead
- Commission hearing on EA Screening Report, with opportunity for public intervention
- Commission decision on EA Screening Report
- Commission hearings on licence applications, with opportunity for public intervention
- Commission decisions on licence applications
