EPA finalized a significant new use rule for 329 per- and polyfluoroalkyl substances that are designated as inactive on the TSCA Chemical Substance Inventory.

EPA released a decision framework for use by the Office of Pollution Prevention and Toxics New Chemicals Division for identification of eye irritation or corrosion hazards for new chemical substances based on prioritization of reproducible, human-relevant data. 

EPA announced the establishment of the Vector Expedited Review Voucher program, which will incentivize the development of new insecticides to control and prevent the spread of vector-borne disease. 

EPA announced the initiation of and seeks comment on the prioritization process for five chemical substances as candidates for designation as high-priority substances for risk evaluation under TSCA and related implementing regulations.

EPA proposed revisions to the regulations for decabromodiphenyl ether and phenol, isopropylated phosphate (3:1), two of the five persistent, bioaccumulative, and toxic chemicals addressed in final rules issued under TSCA in January 2021.

EPA published statements of findings after its review of certain TSCA submissions from September 1, 2023, to September 30, 2023, that certain new chemical substances or significant new uses are not likely to present an unreasonable risk of injury to health or the environment.
