Project Description
The Canadian Nuclear Safety Commission (CNSC) received notice from Cameco Corporation, seeking CNSC approval to replace certain mill services at their Key Lake uranium milling operation in northern Saskatchewan.  

The proposal includes the construction and operation of replacement acid, steam and oxygen plant facilities; construction and operation of ancillary facilities (replacement of storage tank farm and unloading facilities, and new covered gallery); demolition and disposal of the old plant facilities once the new ones are operational; and demolition and disposal of portions of the old ancillary facilities which are no longer required.

Before the Commission makes its decision on Cameco’s application to replace certain mill services at their Key Lake uranium milling operation, 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.
