Environmental Protection Agency December 15, 2023 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Sacramento Metropolitan Air Quality Management District (SMAQMD) portion of the California State Implementation Plan (SIP) concerning a rule submitted to address section 185 of the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.

The Environmental Protection Agency (EPA) is announcing the availability of and soliciting public comment on the document titled: ``2023 Draft Risk Evaluation for Tris(2-chloroethyl) Phosphate (TCEP)'' and related draft charge questions. EPA will be submitting the Draft Risk Evaluation and public comments to peer reviewers who will consider the approach and methodologies utilized. The letter peer review will include review of the analysis of physical-chemical properties, the fate of TCEP in the environment, releases of TCEP to the environment, environmental hazard and risk characterization for terrestrial and aquatic species, and human health hazard and risk characterization for workers, consumers, and the general population. The letter peer review is expected to begin on March 13, 2024, and end on April 12, 2024. A preparatory virtual public meeting will be held on March 5, 2024, for reviewers and the public to comment on and ask questions regarding the scope and clarity of the draft charge questions. Feedback from the letter peer review will be considered in the development of the final TCEP risk evaluation.
