With Congress considering the reconciliation of the Senate and House proposals to the Toxic Substances Control Act (TSCA) legislation for the first time since 1976, chemical management and how it will be affected by new TSCA rules has become a hot button issue in the chemical manufacturing business. Despite President Obama’s long-anticipated Supreme Court nomination taking up much of the spotlight in Congress, legislators are optimistic that broad bipartisan support for the bill will keep it moving forward through the final approval process. A number of the proposed changes remain hotly debated throughout the industry, with the burden of proof, the safeguarding of proprietary information, and the “nomenclature” or inventory section being among the most contentious.
