The Canadian Nuclear Safety Commission (CNSC) has received notice from the Ontario Ministry of Environment of its intent to apply for a licence to implement plans to complete the remediation of the Deloro Mine site, located near the former Village of Deloro, Ontario. The purpose of the proposal is to provide for the long-term onsite management of contaminated soils and low-level radioactive wastes currently located at and in the vicinity of the Deloro Mine site.
CNSC authorization of the project would be provided through a waste nuclear substance licence (WNSL) under the Nuclear Safety and Control Act for the possession and management of nuclear substances.
Before the CNSC makes its decision on the Ministry's application, an EA must be completed in compliance with the Canadian Environmental Assessment Act. The purpose of the EA is to identify the possible environmental effects of the proposed project, and to determine whether these effects can be mitigated before the project is allowed to proceed.
