The Environmental Protection Agency is issuing a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for a heat transfer fluid that is currently the subject of premanufacture notices (PMNs) (here). As a result of the SNUR, persons planning to manufacture, import, or process Pentane, 1,1,1,2,3,3-hexafluoro-4-(1,1,2,3,3,3- hexafluoropropoxy) for an activity that is designated as a significant new use by this rule are to notify EPA at least 90 days in advance. The final rule takes effect April 6.
