On May 20, 2019, the U.S. Environmental Protection Agency (EPA) announced that on May 30, 2019, it will begin publishing Toxic Substances Control Act (TSCA) Section 5 notices including premanufacture notices (PMN), microbial commercial activity notices (MCAN), and significant new use notices (SNUN), their attachments, including any health and safety studies, any modifications thereto, and all other associated information in ChemView -- in the form they are received by EPA, without review by EPA. EPA states that it will not be reviewing confidential business information (CBI)-sanitized filings before publishing. EPA states that this announcement will be the first of several reminders that EPA sends and, in addition, EPA has incorporated a reminder to check accompanying sanitized submissions as part of the Central Data Exchange (CDX) reporting module for TSCA Section 5 notices.
EPA’s announcement states the following as guidance for submitters to take heed of before submitting their TSCA Section 5 notices:
- Verify the asserted CBI claims are correct and consistent; and
- Verify the sanitized versions of the form, attachments, and file names are checked for proper and consistent CBI redactions and that watermarks or stamps indicating CBI are removed.
EPA does not specify how long after submission the documents may be posted, but submitters should expect a very short turn-around. Bergeson & Campbell, P.C. (B&C®) has addressed the topic of CBI before, most recently on our podcast, All Things Chemical™. When completing a PMN, a submitter must take care to ensure that all information that must be protected as CBI is marked as such. A submitter cannot expect EPA to extrapolate a claim for CBI in one part of a form to the rest of the document and its attachments. B&C strongly suggests that a submitter review the sanitized form of an entire document (e.g., a PMN and its attachments) to ensure that all sensitive information is redacted before submitting the document to EPA.
Do not wait until May 30. Begin developing and practicing good CBI practices today.
