The Week Ahead

ELI Marks TSCA Reform Anniversary; EPA Scientists Talk Neurotoxicity

June 27, 2022

EPA chemicals chief Michal Freedhoff will be one of the featured speakers at a full-day seminar marking the sixth anniversary of the reformed TSCA, where she and other current and former top officials will discuss several aspects of the toxics program. Several EPA scientists are slated to speak at the Developmental Neurotoxicity Society’s annual meeting.

TSCA Anniversary

EPA’s Freedhoff, Trump-era chemicals chief Alexandra Dunn and several other current and former top officials will speak at the Environmental Law Institute’s June 29 event, “TSCA Reform -- Six Years Later,” examining implementation of the overhauled law from a variety of angles. The agenda includes sessions on new-chemicals reviews, evaluation and management of risks from existing substances, the “Interface of Science and Policy” under the law, and EPA’s recent push to regulate articles along with isolated chemicals.

Developmental Neurotoxicity

The Developmental Neurotoxicity Society will hold its annual meeting online June 25-29. The agenda includes a host of subjects related to studying and assessing chemicals’ developmental effects, with EPA speakers set to present on environmental justice, behavioral toxicology and drinking water byproducts, among other issues.

Nanotechnology

The Massachusetts Toxics Use Reduction Institute’s (TURI) Science Advisory Board will meet June 29 to continue its long-running discussions on listing carbon nanotubes under the state Toxics Use Reduction Act (TURA) program in response to a petition from environmentalists -- one of several ongoing efforts by groups who see nanomaterials as toxic substances requiring strict regulation.

New Chemicals

June 30 is the deadline for nominees to a new subcommittee of EPA’s Board of Scientific Counselors that will review the “collaborative research program” developed by the chemicals and research offices to overhaul TSCA new-chemicals reviews. So far, stakeholders have focused largely on the program’s potential use of new approach methods (NAMs) to replace animal-based testing in new-chemical assessments -- a shift industry generally favors while environmentalists are urging caution.

Looking Ahead

Asbestos Reporting

July 5 is the deadline for public comments on EPA’s proposed TSCA asbestos reporting rule. As drafted, the rule would create a one-time mandate for companies to turn over data on their imports, manufacturing and processing of the material and products that incorporate it, either intentionally or an impurity at any “reasonably ascertainable” level -- though with exceptions for certain small entities.

The rule would require reporting for a four-year period -- less than environmentalists sought but far more than industry claims is necessary to support TSCA evaluations of asbestos risks.
