The federal Minister of Environment and Climate Change has formally requested more information from Ontario Power Generation (OPG) about its proposed deep geologic repository for low- and intermediate-level waste. The request follows a report submitted by a Joint Review Panel in May 2015 after assessing the proposed project for more than two years.

This request for information does not affect the NWMO’s work with respect to leading a site selection process for Adaptive Phased Management (APM), Canada’s plan for the safe, long-term management of used nuclear fuel.

The process for selecting a site for a used nuclear fuel repository is actively continuing in study areas associated with nine communities in Ontario. We anticipate it will take many years of study to assess whether sites in these areas are suitable to meet the project’s robust technical safety requirements and the requirement for an informed and willing host.

Among the studies requested, the minister has asked for information about potential cumulative effects associated with APM if it were to be sited near OPG’s proposed repository for low- and intermediate-level waste. We will support preparation of this material as required.
