I'll provide some insight into that.
There is a role for the hazard-based approach, which can be incorporated into CEPA. A heavily weighted priority is given to science when it comes to a risk-based approach. Often, the science doesn't always keep pace with the problems we're finding with chemicals on the market, so there's a delay in responding to those challenges.
From a hazard perspective, one of the things you can consider in the context of CEPA is being able to prioritize the opportunities for shifting from chemicals that demonstrate some sort of impacts on the environment and human health from a hazard perspective. I don't think you would get that in the context of solely relying on a risk-based approach.
That said, given that there are gaps in the science in the context of the risk assessments that are being conducted, one of the issues that does not seem to come into play as much as it should is the role of the precautionary principle. Where do you incorporate that when decisions are being made in the context of science gaps?
I'll leave it at that, and if Joe wants to add to it, that would be great.
