SOS Great Lakes (also known as Save Our Saugeen Shore) provides this overview of its analysis:
The location of OPG’s proposed deep geologic repository on the shores of a trans-boundary watershed requires specific attention to environmental effects.
Canada is obliged by its own law, the Canadian Environmental Assessment Act 2012 (CEAA 2012), as well as numerous binational legal obligations and customary international practice, to adhere to these principles.
And in conclusion of its forceful, fully referenced critique, SOS Great Lakes provides this summary:
By missing or bypassing virtually every requirement relating to possible transboundary environmental effects, OPG, the JRP, including its creators (ENVIRONMENT CANADA AND CNSC), who wrote its Terms of Reference (TOR), showed a troubling ignorance of and/or disregard of CANADA’s International Obligations particularly to the US and the US Border States.
