For the substances of highest concern, the regime we are proposing is that specific actions would have to be taken for those substances. In order to define what those substances are, the bill provides authority for the government to develop a regulation to define those.
At the moment, the bill says essentially, at a minimum or for example, that group needs to include virtual elimination, carcinogenicity, mutagenicity, etc. That isn't a problem so long as the actual definition and criteria can be further explicated in a regulation, which in turn can be amended from time to time as science evolves.
