Thanks.
In terms of how we prioritize and what it might mean for your constituents, the worse the chemical, the worse its interactions with other chemicals and the greater its impact on the environment, the more likely we are to target businesses, people or groups of businesses that would release that substance into the environment. We use life-cycle analysis to determine that, which means that the receiving environment is taken into account, which means the impact of these things for years and generations to come are at the centre of what we choose to prioritize—bioaccumulation and so forth.
It also means that we target the businesses that we believe are the most likely to be non-compliant. This means that legitimate businesses that are not engaging in behaviours that would cause us to target them are less likely to see an enforcement official and have greater span to do what it is that they do to employ people and to bring jobs into your community.
That is what is at the centre of it. Looking at the chemicals and the pollutants and their relationship with one another and targeting businesses on that basis is not a simple matter, but we do it, and I believe we do it as well as anybody else in the world does.
