EPA Issues Proposed Rule Adding Significant PFAS Reporting Exemptions

/in , ,

As anticipated, EPA has published a proposed rule that would introduce several significant exemptions to the one-time PFAS reporting requirements under the Toxic Substances Control Act (TSCA) PFAS reporting rule.

The proposal, published November 13, 2025, follows significant industry criticism of the 2023 rule’s expansive scope.  EPA first signaled that it was considering narrowing the rule’s requirements in May of this year, when the agency delayed its implementation for the second time.

“The proposed changes to improve reporting regulations will support [EPA] Administrator [Lee] Zeldin’s ‘Powering the Great American Comeback’ initiative by reducing regulatory reporting burdens and providing greater regulatory certainty to industry, resulting in a net reduction in cost while ensuring that EPA receives the PFAS data that are most relevant to the agency,” the agency said in a press release accompanying the proposed rule.

What are the Proposed Exemptions?

EPA proposes to exempt the following categories from the PFAS reporting requirements:

  • PFAS manufactured (including imported) in mixtures or products at concentrations of 0.1% or lower
  • Imported articles
  • Byproducts not used for commercial purposes
  • Impurities
  • Research and development chemicals
  • Non-isolated intermediates

These exemptions are similar to those under the TSCA Chemical Data Reporting (CDR) rule, with the addition of the 0.1% de minimis exemption.

EPA is also proposing to eliminate the streamlined reporting form for article importers and R&D manufacturers because those entities would now be fully exempt under the proposed rule.  For the same reason, EPA would remove the alternative reporting deadline for small manufacturers that would exclusively report as article importers.

Changes to the Submission Period

EPA’s proposal would likely delay the start of the reporting period once again.  The current opening date is April 13, 2026, but under the proposed rule, the reporting window would begin 60 days after the final rule’s effective date.

If EPA issues a final rule in June 2026—as indicated by the Spring 2025 Unified Agenda—and the rule takes effect 30 days after publication, the reporting period would open in September 2026.  However, because the proposal was released a month earlier than the Unified Agenda projected, EPA may also finalize the rule ahead of schedule, potentially resulting in an earlier start date.

The proposal would also shorten the reporting window from six months to three months, with EPA claiming that submitters “have had adequate time to consider how they intend to comply with the rule.”

Statutory Basis

In the proposed rule, EPA argues that the exemptions would better align the regulation with TSCA section 8, which directs EPA to avoid duplicative reporting, minimize compliance costs on small manufacturers, and limit reporting obligations to persons likely to have relevant information.

EPA also cites TSCA section 2(c), which requires that EPA carry out the statute “in a reasonable and prudent manner” and to “consider the environmental, economic, and social impact of any action.”

At the same time, EPA notes that it may in the future determine that certain currently exempted information “is necessary to support particular regulatory actions.”

Comments on the proposed rule are due December 29, 2025.  More on the TSCA PFAS reporting rule can be found in our archive.

PFAS Reporting Rule Update: OMB Clears Path for EPA to Ease Requirements

/in , ,

EPA is a step closer to easing PFAS reporting requirements for manufacturers and importers after the Office of Management and Budget (OMB) completed its review of a proposed rule on October 24, 2025, that is likely to introduce exemptions.

Background: The Current PFAS Reporting Rule

The Toxic Substances Control Act (TSCA) section 8(a)(7) PFAS reporting rule, finalized in 2023, requires entities that manufactured or imported PFAS in any year from 2011–2022 to report extensive data to EPA.  Unlike other TSCA reporting obligations, the rule does not exempt articles, de minimis quantities, byproducts, or impurities—drawing criticism from industry groups, who argue that its broad scope is both unnecessary and overly burdensome.

As discussed in a previous post, the rule’s original 2024 reporting deadline has already been delayed twice to 2026 because of technical difficulties.  However, in the most recent postponement, EPA signaled that it was considering reopening elements of the rule to align with the Trump administration’s deregulatory agenda.  On August 29, 2025, it submitted the proposal to OMB for regulatory review.

What’s Next

According to the Spring 2025 Unified Agenda, the rulemaking will incorporate “certain exemptions and other modifications to the scope of the reporting rule.”  The proposed rule is expected in December 2025, and EPA plans to finalize the rulemaking in June 2026.

More on the PFAS reporting rule’s requirements can be found in a previous post.

EPA Again Delays PFAS Reporting Rule

/in , ,

On May 13, 2025, EPA issued an interim final rule delaying implementation of the PFAS reporting requirements under the Toxic Substances Control Act (TSCA), citing technical difficulties.

The submission period is now scheduled to begin on April 13, 2026, instead of July 11, 2025.  It will close on October 13, 2026, with an alternate deadline of April 13, 2027, for small manufacturers reporting exclusively as article importers.

The rule states that the delay will “ensure that the project team has adequate time to complete development and testing” of the Central Data Exchange (CDX) reporting tool.  EPA also notes that it will give the agency time to consider reopening elements of the PFAS reporting rule in light of Executive Order 14192: Unleashing Prosperity Through Deregulation, issued by the Trump administration.

This is the second delay to the rule’s implementation.  In September 2024, EPA postponed the original November 2024 start date, also citing incomplete software development.  At the time, the agency attributed the delay to reduced funding.

Congress has since appropriated additional funds for TSCA’s information technology infrastructure in the FY2025 Continuing Resolution, passed just two days before EPA issued the May 13 rule.

Once implemented, the PFAS reporting rule will require all persons who manufactured or imported PFAS for commercial purposes from 2011–2022 to report information to EPA.  More on its requirements can be found here.

EPA Finalizes TSCA Reporting and Recordkeeping Requirements for PFAS

/in , ,

EPA has finalized its Toxic Substances Control Act (“TSCA”) Reporting and Recordkeeping Requirements for Perfluoroalkyl and Polyfluoroalkyl Substance (“PFAS”) rule. The rule offers none of the customary TSCA reporting exemptions, such as the di minimus threshold exemption, article exemption, and research and development exemption. Although industry members voiced significant concerns over the proposed rule, the scope of the rule remains expansive. A summary of the final rule is detailed below.

Who does the final rule apply to?

40 CFR § 705.10 identifies the entities that are covered under the rule. The rule, which Congress mandated through the FY2020 National Defense Authorization Act, applies to all entities that have manufactured and/or imported a PFAS for commercial purposes, including those present in a mixture and in an article since January 1, 2011. Those who have only processed, distributed in commerce, used, and/or disposed of PFAS are not subject to this rule.

Which PFAS must be reported under the final rule?

EPA has identified PFAS subject to the rule by a structural definition rather than a list of substance identities (40 CFR § 705.5). However, EPA will provide a public list of substances that meet this definition on its CompTox Chemical Dashboard. The definition of PFAS using a structural definition is as follows:

  • R-(CF2)-CF(R’)R’’, where both the CF2 and CF moieties are saturated carbons;
  • R-CF2OCF2-R’, where R and R’ can either be F, O, or saturated carbons; and
  • CF3C(CF3)R’R’’, where R’ and R’’ can either be F or saturated carbons.

This differs from the proposed rule, which defined PFAS as “a substance that includes the following structure: R-(CF2)–C(F)(R′)R″, in which both the CF2 and CF moieties are saturated carbons and none of the R groups (R, R′ or R″) can be hydrogen.”

Reporting threshold

There is no reporting threshold or de minimis level for PFAS reporting. The traditional TSCA reporting exemptions, such as byproducts and impurities, and low volume exemptions, are not being upheld under this rule and require reporting.

Reporting standard

40 CFR § 705.15 states that the reporting standard that applies to this rule is information “known or reasonably ascertainable” by the manufacturer. This means “all information in a person’s possession or control, plus all information that a reasonable person similarly situated might be expected to possess, control, or know” (See 40 CFR 704.3). Under this standard, the manufacturer must evaluate not only their current level of knowledge regarding substances that are manufactured or imported, including those in articles, but also any additional information that a reasonable person, similarly situated, would be expected to know, possess, or control.

To obtain the necessary information for reporting, EPA expects the manufacturer/importer to conduct a reasonable inquiry into their own organization and potentially make inquiries outside the organization. According to the Agency, this may require “phone calls or email inquiries to upstream suppliers or downstream users or employers or other agents of the manufacturer, including persons involved in the research and development, import or production, or marketing of the PFAS.”

If data is unknown or not reasonably ascertainable, the submitter should, if possible, submit reasonable estimates. If manufacturers or importers need additional information for reporting, but suppliers are unwilling to provide that information, they can send a request for information through EPA’s reporting tool.

What information must be reported?

The scope of information required is vast. Data elements are detailed at 40 CFR §705.15 and include:

  • Chemical-specific information for all PFAS manufactured each year since January 1, 2011, including PFAS incorporated in mixtures.
  • Categories of use, including information on the sector, industrial processing, commercial and consumer use, and product categories.
  • Concentrations of each PFAS used in consumer and commercial products.
  • Manufactured amounts.
  • Byproduct identification.
  • Environmental and health effects data – which must be submitted according to OECD Harmonized Templates for Reporting Chemical Test Summaries.
  • Worker exposure data.
  • Disposal data.

Reporting on PFAS in Articles

Articles importers are subject to the reporting rule. The fact that there is no de minimis concentration threshold makes the scope of this mandate expansive. Because the known and reasonably ascertainable standard applies to this rule, importers must go beyond simply reviewing the SDSs for the imported articles. To demonstrate compliance with the rule, importers will need to survey their suppliers about the presence of PFAS in all of the articles they have imported since January 1, 2011. However, the rule does not mandate any product testing for article importers.

The rule does exempt some data elements from reporting for PFAS imported in articles, such as byproduct identification, worker exposure data, and disposal data.

R&D exemptions to the reporting requirements

Manufacturers and importers of R&D PFAS substances are subject to the reporting rule.  The reporting requirements are reduced where volumes are below 10 kilograms annually.

Electronic reporting

All information must be submitted electronically through CDX (see 40 CFR § 705.35). A new tool, the Chemical Information Submission System (“CISS”), will be added to the CDX module “Submission for Chemical Safety and Pesticide Program” (“CSPP”). Reporting will be submitted through the CISS, which the Agency is currently developing, and will be live prior to the opening of the reporting period.

CBI claims

PFAS manufacturers reporting under this rule may claim CBI consistent with TSCA section 14, but they must make the CBI claim with their submission for this rule. CBI claims submitted for other reporting requirements will not be considered. See 40 CFR § 705.30 for details.

Reporting timeline

Manufacturers and importers will have one year from the effective date of this rule, November 13, 2023, to collect the data necessary for reporting and an additional six months to submit their reports; reports will be due May 13, 2023. Small manufacturers (as defined in 40 CFR 704.3) will have an additional six months to report, making their reporting deadline November 13, 2024.

Recordkeeping requirements

Manufacturers and importers subject to this rule must maintain records of all documents and information reported to EPA for five years, beginning on the last day of the information submission period.

EPA Releases Initial Regulatory Flexibility Analysis for the Proposed PFAS Reporting Rule

/in ,

On November 25, 2022, EPA released an Initial Regulatory Flexibility Analysis (IRFA) for public comment as part of its development of a rule to collect information about PFAS. The IRFA follows the Agency’s June 2021 proposed rule, which would require all manufacturers and importers of PFAS in any year since 2011 to report information related to chemical identity, categories of use, volumes manufactured and processed, byproducts, environmental and health effects, worker exposure, and disposal. In the proposed rule, EPA certified that the rule would not have a significant impact on a substantial number of small entities under the Regulatory Flexibility Act (RFA). In response to public comments from the June 2021 proposed rule and additional data sources on PFAS-containing imports, EPA convened a Small Business Advocacy Review Panel and prepared the IRFA to investigate further the burdens the proposed rule would place on small businesses.

EPA significantly increased its cost estimates for the proposed rule, stating social costs would be approximately $875 million, from the original $10.8 million estimate, and Agency costs would be approximately $1.5M,  from the originally estimated $948,078.  The IRFA anticipates that in order to report years of production and importation data, small businesses would be expected to pay the lion’s share of these costs, $863.5 million, not the originally anticipated $1.8 million. Additionally, the IRFA details the percentage of small firms that will be impacted by the rule, finding that approximately 93% of manufacturers and 97.3% of article importers affected by the proposed rule are small businesses. The total number of small businesses expected to be impacted is 127,794.

In the IRFA, EPA proposed and requested comment on a variety of regulatory flexibility alternatives, including:

  • Exemptions for businesses with less than $12 million in sales.
  • Exemptions for businesses with less than $6 million in sales.
  • Exemptions for article importers with less than $6 million in sales.
  • Exemptions for article importers with less than $2 million in sales.
  • Limiting the scope of PFAS subject to the rule to a finite list of PFAS, removing the structural definition. (Although EPA expressed concern over the Agency’s inability to list substance identities based on CBI claims.)
  • Exemption for reporting thresholds of either 2,500 lbs. per year or 25,000 lbs. per year.
  • Allow for small businesses, providing a six-month deferral of data submission.
  • Simplified reporting forms for R&D substances manufactured in volumes less than 10 kg. per year — including limiting reporting to company information, generic chemical name, and production volume.
  • Simplified reporting forms for article importers– excluding requiring information on existing environmental and health effects data, environmental release and disposal data, or occupational exposure data.
  • Exemptions for R&D substances, byproducts, impurities, recyclers, and intermediates. (However, EPA stated that these exemptions would limit the Agency’s ability to achieve its goal of better understanding the entire scope of existing information on PFAS.)

The Agency also requested information and comment on items pertaining to CBI, including treatment of chemical identity claims, notice prior to publication on the public TSCA Inventory, and the generic naming of PFAS. These issues were not included in the IRFA and the Updated Economic Analysis. Regarding the treatment of CBI claims, EPA sought to clarify language related to an entity’s knowledge of a specific chemical identity stating:

[A]n entity that does not have knowledge of a specific chemical identity must initiate a joint submission with its supplier or other manufacturer. In these cases, the secondary submitter would be responsible for providing the specific chemical identity and for asserting and substantiating any CBI claims concerning the specific chemical identity. See, e.g.,40 CFR 711.15(b)(3); 711.30(c).

Regarding notice prior to publication on the public TSCA Inventory, EPA sought to clarify that if a submitter reports a PFAS substance by a specific chemical identity and does not assert CBI, that chemical identity will be published on the public Inventory without notice to the submitter. Importantly, EPA requested comment on aligning this provision with the language in the proposed CBI Procedures rule indicating that persons who previously made a CBI claim for the same specific chemical identity will not receive prior notice before the specific chemical identity is moved to the public Inventory. Lastly, EPA clarified that generic names must sufficiently identify the chemical as a PFAS; for example, under TSCA Section 14(c)(1)(C), a generic name for a PFAS that does not contain “fluor” would be rejected as insufficient.
