EPA published on February 8, 2021, a periodic update of the TSCA confidential business information (CBI) review statistics. TSCA Section 14(g)(1) requires that EPA, within 90 days of receipt of a CBI claim:

• Review and make determinations on CBI claims for chemical identity after the chemical substance has been offered for commercial distribution; and
   
• Review and make determinations on a representative subset of at least 25 percent of other CBI claims that are not exempt from substantiation and review.

The updated data summarize the number of CBI cases under review and results of completed reviews through December 28, 2020. In addition, a spreadsheet is available showing the details of completed TSCA CBI determinations through December 28, 2020.

EPA states that making this information publicly available continues to demonstrate its commitment to transparency while fulfilling its responsibilities under TSCA. EPA notes that it has established numerous new processes, systems, and procedures to enable submitters to provide the information required when making confidentiality claims and to facilitate EPA’s review, and where applicable, determinations on these claims.
