With both industry and advocates in favor of stronger federal regulation, what could go wrong? As Richard Denison of the Environmental Defense Fund says, "the devil is in the details." For instance, would stronger federal oversight of toxic chemicals trump laws limiting their use in states like California? EPA's Jackson was silent on that issue, while environmental advocates vowed to fight any move to toss state laws. The American Chemistry Council's Cal Dooley, speaking for manufacturers, said the industry would prefer one nationwide set of rules, but hopes that a stronger federal law will head off any further state actions.
