Thank you, Mr. Chair.
It's to identify the somewhat problematic language of determining, as is required.... It's the same provision, paragraph 77(3)(b) that I referred to earlier, “determining that the presence of the substance in the environment results primarily from human activity.” I think that's probably impossible to determine. I think that question is different from the question, is the substance a naturally occurring one and is it present in the environment? Does it enter the environment or is it present in the environment and did humans release it?--that question is different from whether it “results primarily”.
I simply point out that it would be very difficult to determine whether and how it results primarily from human activity, so it's a problematic phrase.
