The American Chemistry Council (ACC) is urging EPA to withdraw, revise and re-propose its pending Toxic Substances Control Act (TSCA) data collection rule for nanoscale materials, saying the existing proposal is unclear on which substances must be reported and arguing that certain requirements lack sufficient scientific backing. At a June 11 public meeting on the rule at EPA's headquarters in Washington, D.C., ACC and other chemical sector groups sought to narrow the scope of the proposal, pushing for clearer guidance on reportable materials and additional exemptions from reporting. Industry also argued that a provision for notifying EPA in advance of future manufacturing risks stigmatizing nanomaterials as a class, something the agency has stated it does not intend. The early industry push-back could hint at the comments groups will find on the proposed TSCA section 8(a) nano reporting and recordkeeping rule that EPA published in the April 6 Federal Register.
