As reported in our January 11, 2017, blog item, the January 12, 2017, final rule establishes reporting and recordkeeping requirements for certain discrete forms of chemical substances that are manufactured or processed at the nanoscale. Under the rule, manufacturers and processers, or persons who intend to manufacture or process these chemical substances must report certain information to EPA. The information to be reported includes, insofar as known to or reasonably ascertainable by the person making the report, the specific chemical identity, production volume, methods of manufacture and processing, exposure and release information, and existing information concerning environmental and health effects. Persons who manufacture or process a discrete form of a reportable chemical substance at any time during the three years prior to August 14, 2017, the effective date of the final rule, must report to EPA one year after the effective date of the final rule. There is also a standing one-time reporting requirement for persons who intend to manufacture or process a discrete form of a reportable chemical substance on or after the effective date of the rule. These persons must report to EPA at least 135 days before manufacture or processing of that discrete form. More information regarding the final rule is available in our January 12, 2017, memorandum EPA Promulgates Final TSCA Reporting and Recordkeeping Rule for Nanoscale Materials.
