⚗️EPA Enforces New Significant Use Rules for Chemical Substances

EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification; made an appropriate determination regarding that notification; and taken such actions as required by that determination.

⚗️EPA Draft Risk Evaluations for Dibutyl and Diethylhexyl Phthalate

The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on the draft risk evaluations under the Toxic Substances Control Act (TSCA) for Dibutyl Phthalate (DBP) (CASRN 84-74-2) and Diethylhexyl Phthalate (DEHP) (CARSN 117-81-7). 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 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. EPA used the best available science to prepare this draft risk evaluation and to preliminarily determine, based on the weight of scientific evidence, that DBP and DEHP present unreasonable risk to health and the environment driven primarily by certain conditions of use analyzed in the draft evaluations.
