ARTICLE — Lynn L. Bergeson and L. Claire Hansen Author “Toxic Substances Law Creating More Confusion for Legal Teams and Public,” For Chemical Processing: This article focuses on one of many abrupt, and in some views, unlawful, U.S. Environmental Protection Agency (EPA) policy shifts frustrating lawyers and confusing the public. EPA moved in 2021 from a “conditions of use” approach to evaluating chemical risk to a “whole chemical” approach. This seemingly modest change is a key reason why lawyers advising chemical stakeholders are struggling and why there may be a lot of Toxic Substances Control Act (TSCA) litigation in EPA’s future.


EPA Updates TSCA Inventory, Plans Next Update In Summer 2023: On February 16, 2023, EPA announced that the latest TSCA Chemical Substance Inventory is now available on its website.

Finally, EPA made certain technical corrections and conforming changes, including updating standards within the definitions section, clarifying language as it relates to production, and creating greater flexibilities for the third-party certification process. The final rule will be effective March 23, 2023. The incorporation by reference (IBR) of certain material listed in the rule is approved by the Director of the Federal Register as of March 23, 2023. The IBR of certain other material listed in the rule was approved by the Director of the Federal Register on February 10, 2017, and February 7, 2018.

GAO Report Finds Workforce Planning Gaps Contributed To EPA’s Missed TSCA Deadlines: The U.S. Government Accountability Office (GAO) released a report on February 23, 2023, entitled “EPA Chemical Reviews: Workforce Planning Gaps Contributed to Missed Deadlines.” GAO evaluated the extent to which EPA met selected TSCA deadlines for reviewing existing and new chemicals since June 2016, and to which EPA engaged in workforce planning for implementing its chemical review responsibilities. GAO identified five principles with which federal agencies’ strategic workforce planning efforts should align. According to the report, while EPA officials agree that the principles are “relevant and reasonable for its TSCA workforce planning efforts,” they have not yet developed a process or timeline to align fully such efforts with these principles. For more information, please read our February 24, 2023, memorandum.

EPA Releases Proposed Approach For Considering Cumulative Risks Under TSCA: On February 27, 2023, EPA announced the availability of and solicited public comment on two draft documents that are being submitted to the Science Advisory Committee on Chemicals (SACC) for peer review: “Draft Proposed Principles of Cumulative Risk Assessment under the Toxic Substances Control Act” (draft proposed principles) and “Draft Proposed Approach for Cumulative Risk Assessment of High-Priority Phthalates and a Manufacturer-Requested Phthalate under the Toxic Substances Control Act” (draft proposed approach). 88 Fed.

EPA OIG Finds EPA’s January 2021 PFBS Toxicity Assessment Did Not Uphold EPA’s Commitments To Scientific Integrity And Information Quality: EPA Office of Inspector General (OIG) announced on March 7, 2023, that EPA did not follow the typical intra-agency review and clearance process during the development and publication of the January 2021 PFBS toxicity assessment. OIG states that during final clearance, “a political appointee directed that a last-minute review be conducted of the uncertainty factors used to calculate toxicity values, resulting in a scientific disagreement that caused delay, confusion, and significant changes to the near-final, peer-reviewed work product.” While EPA staff expressed scientific integrity concerns about the last-minute review and risks to public health, EPA lacked policies and procedures to address these concerns. According to OIG, without updates to policies and procedures, EPA cannot fulfill its commitment to scientific integrity and information quality.
