This final rule addresses the recommendations of the 39th TSCA Interagency Testing Committee (ITC) Report by adding 19 of 23 recommended nonylphenol ethoxylates to the Toxic Substances Control Act (TSCA) section 8(a) Preliminary Assessment Information Reporting (PAIR) rule. The TSCA ITC in its 39th Report to EPA revised the TSCA section 4(e) Priority Testing List by recommending testing for 23 nonylphenol ethoxylates, 19 of which are associated with unique Chemical Abstract Service (CAS) Registry numbers. The ITC recommendations are given priority consideration by EPA in promulgating TSCA section 4 test rules. This PAIR rule will require manufacturers (including importers) of the 19 CAS-numbered substances identified in this document to report certain production, use, and exposure-related information to EPA. This action also removes a stay for TSCA section 8(a) PAIR and section 8(d) Health and Safety Data Reporting rules issued previously for 18 nonylphenol ethoxylates recommended by the TSCA ITC in its 38th Report to EPA and removes those 18 chemicals from these reporting rules.
