Working against science quality will be the aggressive deadlines set by CS-21 for issuance of safety standards. The Act’s sponsors expect the EPA’s reformed TSCA program to conduct safety assessments and issue risk management requirements for 25 chemicals a year, once the program is fully implemented. Consider that the EPA’s IRIS program did not complete a risk assessment for even one substance during all of 2014.

Getting valid safety assessments out of a reformed TSCA program – so the composites industry is allowed to continue using styrene – will require aggressive and continuing attention by ACMA and other stakeholders and effective Congressional oversight. But the industry still has better odds here than under any of the other options.
