From our perspective, we believe the statute is sufficiently robust. It is a risk-based system. As I mentioned previously, when we do a risk assessment it inherently takes into account cumulative exposure considerations and multiple exposure considerations. It looks at the availability of all evidence, and you look collectively at how that is going to be integrated into your decision-making model. A risk-based approach allows those considerations to be taken into account.
I would submit that the statute itself is already sufficiently robust and specifically designed to account for those circumstances. There are many examples where cumulative exposure does get integrated into the decision-making matrix.
