When we have a case like this, we typically retain expert witnesses who are toxicologists to look at the particular facility, its proposed emissions, how those will relate to the community around it, and how they'll meet the relevant provincial standards or other applicable standards.
We're certainly not the engineering and the toxicology experts. However, those are the kinds of things we examine. We then take those to whatever tribunal or decision-maker is looking at whether that facility should be licensed.
In some proposals the argument is made that it's a greener solution because of greenhouse gas reduction impacts, or other solutions, like alleviating landfill. We talk about the fact that you need to look at the whole picture. If you're trading off for emissions that have health impacts, that might not be a good trade, especially, as you say, if it's an area that already has a lot of other emissions happening in the mix.
It's a technology-specific analysis that needs expertise applied to it.
