How will changes to the TRI/PFAS reporting rule affect your facility?

How will changes to the TRI/PFAS reporting rule affect your facility?

On October 31, the U.S. Environmental Protection Agency (EPA) published an update to a rule, originally proposed in December 2022, that eliminates a key exemption related to Toxics Release Inventory (TRI) reporting for certain per- and polyfluoroalkyl substances (PFAS). Now that the exemption removal is finalized, TRI reports will need to reflect this change for the 2024 submittal, which will be due on July 1, 2025.

Primary impacts of TRI reporting rule update

Since the 2020 reporting year, facilities that manufacture, process, or otherwise use PFAS-listed chemicals have been required to prepare threshold determination calculations for these chemicals to ascertain if one or more PFAS-listed chemicals meet or exceed the applicable 100-pound annual reporting threshold. Since that time, low concentrations of TRI-listed PFAS in mixtures have been eligible for the de minimis exemption, which means they were not required to be included in threshold calculations. With the EPA’s recent update to the rule, facilities will no longer be able to use the de minimis exemption for PFAS-listed chemicals starting in the 2024 reporting year, even if facilities have been able to do so under previous reporting years. For example, if a facility uses fire suppressants that contain one or more PFAS-listed chemicals at concentrations less than de minimis levels, the facility will now need to account for those lower concentrations beginning with the 2024 reporting year.

The updated rule also eliminates a reporting exemption previously available to suppliers and manufacturers of products that contain PFAS at concentrations below certain levels. This exemption elimination is intended to prevent the use of proprietary and trade-secret protections to mask the presence of PFAS in products. While this change may make identification of the presence or absence of PFAS easier using safety data sheets (SDSs), facilities might find ways to circumnavigate parts of it, making the updated rule less effective. For example, PFAS in certain products may be identified using atypical synonyms in the place of more common names. It is also possible that the PFAS used in the product may not be included as part of a standard analytical list or may not be subject to current regulatory criteria (but may be included as part of future regulatory actions). Additionally, SDS documentation impacted by the new rule may not be updated immediately, and old documentation may linger for several years before it is updated to be compliant. While the elimination of this exemption is intended to help manufacturers obtain the necessary information for TRI reporting, the potential ways to circumnavigate the reporting rules and outdated SDS documentation may still present a challenge for industrial sources that are evaluating PFAS concentrations through their vendor supply chain to comply with the updated reporting rule.

Getting started on 2024 TRI reporting

What does all this mean? To summarize, the first step to prepare for the 2024 reporting year is to identify any mixtures previously excluded from the threshold determination process due to the de minimis exemption. Then identify the PFAS concentrations in the listed mixtures. While these steps may sound straightforward, identifying potential sources of PFAS and deciphering SDS documentation can be a challenging endeavor.

With nearly two decades of experience with PFAS-related concerns, Barr’s PFAS team can help you review and interpret SDS documentation to identify potential sources of PFAS in products used in your manufacturing or operational stream. We’ll work closely with you to identify potential products that may contain, or are likely to contain, PFAS as part of their composition to keep your company informed about your waste stream or end-user products.
