Reg. 44300.  The notice includes a summary of the approach used by EPA to support the proposed designations, the proposed designation for each of the chemical substances, and instructions on how to access the chemical-specific information, analysis, and basis used by EPA to make the proposed designation for each chemical substance.  Comments are due November 21, 2019.  More information is available in our August 26, 2019, memorandum, “EPA Proposes to Designate 20 Chemical Substances as High-Priority Substances for Risk Evaluation under TSCA.”
