EPA Finalizing SNUR for Phenol, 2,4-dimethyl-6-(1-methylpentadecyl )

The EPA is finalizing a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for phenol, 2,4-dimethyl-6-(1-methylpentadecyl)- (PMN P-94-209; CAS No. 134701-20-5). That means persons planning to manufacture, import or process the chemical substance for a purpose identified as a significant new by the rule must notify the EPA at least 90 days in advance. The notification would enable the EPA to evaluate the substance’s intended use and, if necessary, prohibit or limit that activity before it occurs, the agency said. Responding to public comments, the EPA has included some exemptions, including when the substance’s presence in a mixture is less than 1 percent. There’s also an exemption from all requirements of the rule, including record keeping, once the PMN substance has been incorporated into polymer matrices. The final rule will go into effect August 15.
