🔬EPA Announces Rescheduled Meetings on 1,3-Butadiene Risk Evaluation
The Environmental Protection Agency (EPA or Agency) is announcing the rescheduled meeting dates of the Science Advisory Committee on Chemicals (SACC) that had been previously scheduled for February 2025 to consider and review the draft risk evaluation for 1,3- butadiene. The rescheduled preparatory meeting for the SACC to consider the scope and clarity of the revised draft charge questions for the peer review will now be held on March 25, 2025, and the rescheduled peer review meeting for the SACC to consider the draft documents and public comments will now be held on April 1 to 4, 2025. As previously announced, these meetings will be virtual public meetings of the SACC, with the public invited to comment on the scope and clarity of the revised draft charge questions for the peer review and the draft risk evaluation and related documents, including a new supplement of preliminarily refined risk estimates for 1,3-butadiene released from facilities in advance of and during the peer review meeting. The SACC will consider the comments during their discussions.

The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on the draft scope of the risk evaluation to be conducted under the Toxic Substances Control Act (TSCA) for vinyl chloride (ethene, chloro-; CASRN 75-01-4). Under TSCA, the scope documents must include the conditions of use, hazards, exposures, and the potentially exposed or susceptible subpopulations that EPA expects to consider in conducting the risk evaluation for this chemical substance. The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use, including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, and without consideration of costs or non-risk factors.
Learn More⚖️EPA Draft Risk Evaluation for DCHP Under TSCA - Comment Deadline March 2025
The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on a draft risk evaluation under the Toxic Substances Control Act (TSCA) for Dicyclohexyl phthalate (DCHP) (1,2-benzenedicarboxylic acid, 1,2- dicyclohexyl ester) (CASRN 84-61-7). The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, without consideration of costs or other non-risk factors, including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, under the conditions of use. EPA has used the best available science to prepare this draft risk evaluation and to preliminarily determine that DCHP poses unreasonable risk to human health.
