The U.S. Environmental Protection Agency (EPA) announced on January 5, 2021, that it is reopening the reporting period under the Toxic Substances Control Act (TSCA) Inventory notification active-inactive rule where companies identified chemicals that were manufactured, imported, or processed in the United States during the ten-year time period ending on June 21, 2016. As reported in our June 26, 2017, memorandum, “EPA Issues Final TSCA Framework Rules,” the final TSCA Inventory notification (active-inactive) rule established a retrospective electronic notification of chemical substances on the TSCA Inventory that were manufactured (including imported) for nonexempt commercial purposes during the ten-year time period ending on June 21, 2016, with provision to also allow notification by processors. From August 11, 2017, through October 5, 2018, chemical manufacturers and processors provided information on which chemicals were manufactured, imported, or processed in the United States over the past ten years. The reporting period included an opportunity for submitters to assert claims to retain specific chemical identities as confidential business information (CBI). In May 2020, EPA posted an interim list of chemicals expected to lose their CBI status and move to the public portion of the TSCA Inventory. In its January 5, 2021, announcement, EPA states that it since become aware of “submitter confusion and issues regarding CBI claims” during the initial reporting period. EPA is allowing companies to submit, amend, or withdraw filings under the TSCA Inventory notification (active-inactive) rule to maintain existing CBI claims for specific chemical identity. The reporting period will reopen 30 days after publication in the Federal Register and run for 60 days after that date.
