The purpose of the hearing: “Strengthening Public Health Protections by Addressing Toxic Chemical Threats.”
Mainly it is a mechanism for EPW Chair Boxer to address her concerns related to the bipartisan Safe Chemicals Improvement Act bill introduced by the late Senator Frank Lautenberg and Senator David Vitter. The bipartisan bill came as a surprise only a month after Lautenberg had reintroduced his Safe Chemicals Act bill. Boxer called the hearing in an effort to ensure that industry had not unduly influenced the ailing Lautenberg and gotten a death-bed commitment for an industry-friendly bill that is dramatically different than Lautenberg's own bill.
Other concerns to be addressed with be the preemption provisions, which the state of California (and other states) are concerned will block any state action on toxic chemicals even if EPA does not take sufficient action to protect human health and the public.
