Changes to Reporting Requirements for Per- and Polyfluoroalkyl
Substances and to Supplier Notifications for Chemicals of Special
Concern; Community Right-to-Know Toxic Chemical Release Reporting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing to add
per- and polyfluoroalkyl substances (PFAS) subject to reporting under
the Emergency Planning and Community Right-to-Know Act (EPCRA) and the
Pollution Prevention Act (PPA) pursuant to the National Defense
Authorization Act for Fiscal Year 2020 (NDAA) to the list of Lower
Thresholds for Chemicals of Special Concern (chemicals of special
concern). These PFAS already have a lower reporting threshold of 100
pounds. The addition of these PFAS to the list of chemicals of special
concern will cause such PFAS to be subject to the same reporting
requirements as other chemicals of special concern (i.e., it would
eliminate the use of the de minimis exemption and the option to use
Form A and would limit the use of range reporting for PFAS). Removing
the availability of these burden-reduction reporting options will
result in a more complete picture of the releases and waste management
quantities for these PFAS. In addition, EPA is proposing to remove the
availability of the de minimis exemption for purposes of the Supplier
Notification Requirements for all chemicals on the list of chemicals of
special concern. This change will help ensure that purchasers of
mixtures and trade name products containing such chemicals are informed
of their presence in mixtures and products they purchase.

     Federal facilities.
    A more detailed description of the types of facilities covered by
the NAICS codes subject to reporting under EPCRA section 313 can be
found at: https://www.epa.gov/toxics-release-inventory-tri-program/tri-covered-industry-sectors. To determine whether your facility would be
affected by this action, you should carefully examine the applicability
criteria in part 372, subpart B of title 40 of the Code of Federal
Regulations. Federal facilities are required to report under Executive
Order 14008 (https://www.govinfo.gov/content/pkg/FR-2021-02-01/pdf/2021-02177.pdf), as explained in the Council on Environmental Quality's
2021 memorandum to Chief Sustainability

Officers (http://www.epa.gov/sites/default/files/2021-04/documents/final_ceq_memo_on_tri_april_2021.pdf). If you have questions regarding
the applicability of this action to a particular entity, consult the
person listed under FOR FURTHER INFORMATION CONTACT.

B. What action is the Agency taking?

    EPA is proposing to add all PFAS included on the Toxics Release
Inventory (TRI) pursuant to sections 7321(b) and 7321(c) of the 2020
NDAA to the list of chemicals of special concern (40 CFR 372.28). (EPA
maintains a list of PFAS added to the TRI list pursuant to the NDAA:
https://www.epa.gov/toxics-release-inventory-tri-program/list-pfas-added-tri-ndaa.) The addition of these PFAS to the list of chemicals of
special concern will align reporting requirements for these PFAS with
other chemicals of special concern. This will likely result in
additional Form R reports being filed for these PFAS due to the removal
of the availability of the de minimis exemption and the option to use
Form A. It will also limit the use of range reporting, which will
capture more specific information for PFAS added pursuant to sections
7321(b) and 7321(c) of the NDAA.
    In addition, EPA is proposing to remove the availability of the de
minimis exemption under the Supplier Notification Requirements (40 CFR
372.45) for facilities that manufacture or process any chemicals
included on the list of chemicals of special concern.

C. What is the Agency's authority for this action?

    This action is issued under EPCRA sections 313, 42 U.S.C. 11023 and
328, 42 U.S.C. 11048. EPCRA is also referred to as Title III of the
Superfund Amendments and Reauthorization Act of 1986.

D. Why is the Agency taking this action?

    EPA is taking this action to increase the data collected for PFAS.
Removing the availability of certain burden-reduction reporting options
will result in a more complete picture of the releases and waste
management quantities for PFAS. This proposed change would increase the
number of TRI reports on listed PFAS and the amount of information
provided on such reports, resulting in more information on the waste
management of these chemicals available to the Agency, as well as to
the public. In addition, this action will increase data collected for
all chemicals of special concern by eliminating the de minimis
exemption for purposes of the Supplier Notification Requirements for
all chemicals on the list of chemicals of special concern. The
elimination of this exemption from Supplier Notification Requirements
will ensure that purchasers of mixtures and trade name products
containing such chemicals are informed of their presence in mixtures
and products they purchase.

E. What are the estimated incremental impacts of this action?

    EPA prepared an economic analysis for this action entitled,
``Economic Analysis for the Proposed Changes to Reporting Requirements
for Per- and Polyfluoroalkyl Substances and to Supplier Notifications
Requirements for Chemicals of Special Concern; Community Right-to-Know
Toxic Chemical Release Reporting,'' which presents an analysis of the
costs of the proposed reporting changes for PFAS and other chemicals of
special concern (Ref. 1). EPA estimates that this action would result
in an additional 605 to 1,997 Form R reports being filed annually. EPA
estimates that the costs of this action will be approximately
$3,064,271 and $10,114,734 in the first year of reporting and
approximately $1,459,215 and $4,816,518 in the subsequent years. In
addition, EPA has determined that, of the 467 to 1,313 small businesses
affected by this action, none are estimated to incur annualized cost
impacts of more than 1% of revenues. Thus, this action is not expected
to have a significant adverse economic impact on a substantial number
of small entities.

II. Background Information

A. What is EPCRA section 313?

    EPCRA section 313, 42 U.S.C. 11023 (also known as the Toxics
Release Inventory (TRI)), requires certain facilities that manufacture,
process, or otherwise use listed toxic chemicals in amounts above
reporting threshold levels to report their environmental releases and
other waste management quantities of such chemicals annually. These
facilities must also report pollution prevention and recycling data for
such chemicals, pursuant to PPA section 6607, 42 U.S.C. 13106. Note
that TRI does not cover all chemicals, facilities, or types of
pollution (see https://www.epa.gov/toxics-release-inventory-tri-program/what-toxics-release-inventory for information on which
chemicals and facilities are regulated under TRI).
    TRI provides information about releases of toxic chemicals from
covered facilities throughout the United States; however, TRI data do
not reveal whether or to what degree the public is exposed to listed
chemicals. TRI data can, in conjunction with other information, be used
as a starting point in evaluating such exposures and the risks posed by
such exposures. The determination of potential risk to human health
and/or the environment depends upon many factors, including the
toxicity of the chemical, the fate of the chemical in the environment,
and the amount and duration of human or other exposure to the chemical.
    For more information on TRI, visit the TRI website at www.epa.gov/tri. Additionally, via this website, EPA provides a Factors to Consider
When Using Toxics Release Inventory Data document (https://www.epa.gov/system/files/documents/2022-02/factorstoconsider_approved-by-opa_1.25.22-copy.pdf), which helps explain some of the uses, as well as
limitations, of data TRI collects.

B. What are PFAS?

    PFAS are synthetic organic compounds that do not occur naturally in
the environment. PFAS contain an alkyl carbon chain on which the
hydrogen atoms have been partially or completely replaced by fluorine
atoms. In general, the strong carbon-fluorine bonds of PFAS make them
resistant to degradation and thus highly persistent in the environment
(Refs. 2 and 3). Some of these chemicals have been used for decades in
a wide variety of consumer and industrial products (Refs.

2 and 3). Some PFAS have been detected in wildlife indicating that at
least some PFAS have the ability to bioaccumulate (Ref. 3). Because of
the widespread use of PFAS in commerce and their tendency to persist in
the environment, most people in the United States have been exposed to
PFAS (Refs. 2, 4 and 5). Some PFAS can accumulate in humans and remain
in the human body for long periods of time (e.g., months to years)
(Refs. 2 and 3), as a result, several PFAS have been detected in human
blood serum (Refs. 2, 3, 4, and 5).

C. What PFAS have been added to the TRI list?

    On December 20, 2019, the NDAA was signed into law (Pub. L. 116-92,
https://www.congress.gov/public-laws/116th-congress). The NDAA included
two provisions that automatically add PFAS to the TRI list. First,
section 7321(b) of the NDAA added to the TRI list, effective January 1,
2020, 14 chemicals by name and/or Chemical Abstracts Service Registry
Number (CASRN) and additional PFAS that meet specific criteria. On June
22, 2020 (85 FR 37354) (FRL-10008-09), EPA updated the TRI list in the
CFR to reflect the 172 non-CBI PFAS added to TRI by section 7321(b).
    Additional PFAS are added to the TRI list on an annual basis by the
NDAA. Specifically, PFAS that meet the criteria in section 7321(c) of
the NDAA are deemed added to the TRI list on January 1 of the year
after specific criteria are met. Through this provision, the NDAA will
continue to add PFAS to the TRI list over time as additional PFAS meet
the criteria outlined in 7321(c). The criteria of section 7321(c)
require the addition to the TRI list of certain PFAS after any one of
the following dates:
     Final Toxicity Value. The date on which the Administrator
finalizes a toxicity value for the PFAS or class of PFAS;
     Significant New Use Rule. The date on which the
Administrator makes a covered determination for the PFAS or class of
PFAS;
     Addition to Existing Significant New Use Rule. The date on
which the PFAS or class of PFAS is added to a list of substances
covered by a covered determination;
     Addition as an Active Chemical Substance. The date on
which the PFAS or class of PFAS to which a covered determination
applies is:
    --Added to the list published under section 8(b)(1) of the Toxic
Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.) and designated
as an active chemical substance under TSCA section 8(b)(5)(A); or
    --Designated as an active chemical substance under TSCA section
8(b)(5)(B) on the list published under TSCA section 8(b)(1).
    EPA updates the TRI list in the CFR to reflect the PFAS added to
TRI by section 7321(c) of the NDAA. The first update rule identifying
PFAS that met the 7321(c) criteria during 2020 was published on June 3,
2021 (86 FR 29698) (FRL-10022-25).
    To date, section 7321 of the NDAA has added a total of 180 PFAS to
the TRI list (https://www.epa.gov/tri/PFAS). A complete list of the
PFAS added to the TRI list can be found at: https://www.epa.gov/toxics-release-inventory-tri-program/list-pfas-added-tri-ndaa. In addition,
the NDAA established a manufacture, processing, or otherwise use
reporting threshold of 100 pounds for each of the PFAS added to the TRI
list by sections 7321(b) and 7321(c) of the NDAA. In the first year of
reporting for the initial 172 listed PFAS, EPA only received 89 reports
from 38 facilities covering 43 different PFAS.

III. What changes is EPA proposing to make to the TRI reporting
requirements?

A. Designating PFAS Automatically Added to the TRI List by the 2020
NDAA as Chemicals of Special Concern

    EPA is proposing to add all PFAS included on the TRI list pursuant
to sections 7321(b) and 7321(c) of the NDAA (see 40 CFR 372.65(d) and
(e)) to the list of chemicals of special concern at 40 CFR 372.28. EPA
first created the list of chemicals of special concern to increase the
utility of TRI data by ensuring that the data collected and shared
through TRI are relevant and topical (64 FR 58666, 58668 October 29,
1999 (FRL-6389-11)). EPA lowered the reporting thresholds for chemicals
of special concern because even small quantities of releases of these
chemicals can be of concern. The first chemicals that were added to the
list of chemicals of special concern were those identified as
persistent, bioaccumulative and toxic (PBT) chemicals which, except for
the dioxin and dioxin-like compounds category, have reporting
thresholds of either 10 or 100 pounds depending on their persistent and
bioaccumulative properties (64 FR 58666, October 29, 1999 (FRL-6389-
11)). Chemicals of special concern are also excluded from the de
minimis exemption, may not be reported on Form A (Alternate Threshold
Certification Statement), and have limits on the use of range
reporting.
    The de minimis exemption allows facilities to disregard small
concentrations of TRI chemicals not classified as chemicals of special
concern in mixtures or other trade name products when making threshold
determinations and release and other waste management calculations. The
de minimis exemption does not apply to the manufacture of a TRI
chemical except if that chemical is manufactured as an impurity and
remains in the product distributed in commerce, or if the chemical is
imported below the appropriate de minimis level. The de minimis
exemption does not apply to a byproduct manufactured coincidentally as
a result of manufacturing, processing, otherwise use, or any waste
management activities.
    The Form A provides facilities that otherwise meet TRI-reporting
thresholds the option of certifying on a simplified reporting form
provided that they do not exceed 500 pounds for the total annual
reportable amount (subsequently in this document) for that chemical,
and that their amounts manufactured, processed, or otherwise used do
not exceed 1 million pounds. All chemicals of special concern (except
certain instances of reporting lead in stainless steel, brass, or
bronze alloys) are excluded from Form A eligibility. Form A does not
include any information on releases or other waste management. Nor does
it include source reduction information or any other chemical-specific
information other than the identity of the chemical.
    For certain data elements (Part II, Sections 5, 6.1, and 6.2 of
Form R), for chemicals not classified as chemicals of special concern,
the reportable quantity may be reported either as an estimate or by
using the range codes that have been developed. Currently, TRI
reporting provides three reporting ranges: 1-10 pounds, 11-499 pounds,
and 500-999 pounds.
    The availability of these burden reduction tools is inconsistent
with a concern for small quantities of the chemicals and the expanded
reporting that was sought for chemicals with lower reporting
thresholds. In the preamble to the 1999 rule, EPA outlined the reasons
for promulgating the de minimis exemption (e.g., that facilities had
limited access to information and that low concentrations would not
contribute to the activity threshold) and determined that those
rationales did not apply to chemicals of special concern. Id. at 58670.
Among the reasons provided, EPA explained that even minimal releases of
persistent bioaccumulative chemicals may result in significant adverse
effects and can reasonably be expected to significantly

contribute to exceeding the proposed lower threshold. Id. EPA also
determined that facilities reporting on chemicals of special concern
could not avail themselves of Form A reporting because the information
provided on Form As is ``insufficient for conducting analyses'' on
chemicals of special concern and would be ``virtually useless for
communities interested in assessing risk from releases and other waste
management'' of such chemicals (i.e., the Form A does not include
estimated release and other waste management quantities). Id. Lastly,
EPA eliminated range reporting for chemicals of special concern because
the use of ranges could misrepresent data accuracy for PBT chemicals
because the low or the high-end range numbers may not really be that
close to the estimated value. Id. For the full discussion, see
Persistent Bioaccumulative Toxic (PBT) Chemicals; Lowering of Reporting
Thresholds for Certain PBT Chemicals; Addition of Certain PBT
Chemicals; Community Right-to-Know Toxic Chemical Reporting (Proposed
rule January 5, 1999, 64 FR 688 (FRL-6032-3) and Final rule October 29,
1999, 64 FR 58666, (FRL-6389-11)).
    EPA is proposing to determine that PFAS added to EPCRA section 313
by sections 7321(b) and 7321(c) of the NDAA should be categorized as
chemicals of special concern and added to the list in 40 CFR 372.28.
The NDAA set a 100-pound reporting threshold for PFAS added by sections
7321(b) and 7321(c), which indicates a concern for small quantities of
such PFAS. EPA is therefore proposing to determine that the
availability of certain burden reduction tools (i.e., de minimis
levels, Form A, and range reporting) are not justified for these
chemicals as the availability of these tools is inconsistent with a
concern for small quantities.
    Further, due to the strength of the carbon-fluorine bonds, many
PFAS can be very persistent in the environment (Refs. 2, 3, and 6).
Persistence in the environment allows PFAS concentrations to build up
over time; thus, even small releases can be of concern. As with PBT
chemicals, permitting reporting facilities to continue to rely on the
burden reduction tools (de minimis levels, Form A, and range reporting)
would eliminate reporting on potentially significant quantities of the
listed PFAS. As explained in more detail below, EPA's rationale for
eliminating these burden reduction tools for PBT chemicals (January 5,
1999, 64 FR 714-716) applies equally well to PFAS.
    The de minimis exemption allows facilities to disregard
concentrations of TRI listed chemicals below 1% (0.1% for carcinogens)
in mixtures or other trade name products they import, process, or
otherwise use in making threshold calculations and release and other
waste management determinations. Since the de minimis level is based on
relative concentration rather than a specific amount, the application
of this exemption to PFAS listed under sections 7321(b) and 7321(c)
could allow significant quantities of such PFAS to be excluded from TRI
reporting by facilities. For example, if a facility imports, processes,
or otherwise uses 100,000 pounds of a mixture or trade name product
that contains 0.5% of a listed PFAS, then 500 pounds (or five times the
reporting threshold) would be disregarded. This exclusion is
inconsistent with a concern for small quantities of PFAS. Many PFAS are
used in products below the established de minimis levels (Refs. 4 and
7), and the continued availability of the exemption for PFAS would
permit facilities to discount those uses when determining whether an
applicable threshold has been met to trigger reporting.
    The Form A provides certain covered facilities the option of
submitting a substantially shorter form with a reduced reporting burden
(Ref. 8). For example, the Form A does not require facilities to report
any information on releases (e.g., releases through fugitive or non-
point air emissions, discharges to streams or water bodies) or waste
management quantities. Facilities can qualify to file a Form A if the
total annual reportable amount for the listed chemical does not exceed
500 pounds, and the amounts manufactured, processed, or otherwise used
do not exceed 1 million pounds. The reportable amounts include amounts
released at the facility (including disposed of within the facility),
treated at the facility (as represented by amounts destroyed or
converted by treatment processes), recovered at the facility as a
result of recycling operations, combusted for the purpose of energy
recovery at the facility, and amounts transferred from the facility to
off-site locations for the purpose of recycling, energy recovery,
treatment, and/or disposal. This means that facilities that are
required to report data on PFAS and also qualify to file a Form A will
not be providing specific quantity data on up to 500 pounds of a listed
PFAS (five times the reporting threshold). For reporting year 2020,
approximately 10% of the reporting forms submitted for the listed PFAS
were Form As (i.e., reporting for TRI reflects 93 active reporting
forms of which 84 were Form Rs and 9 were Form As).
    While the Form A does provide some general information on the
quantities of the chemical that the facility manages as waste, this
information may be insufficient for conducting analyses on PFAS and may
be less meaningful for communities interested in assessing risk from
releases of PFAS. The threshold category for amounts managed as waste
does not include quantities released to the environment as a result of
remedial actions or catastrophic events not associated with production
processes (section 8.8 of Form R). Thus, the waste threshold category
in Form A does not include all releases. Given that even small
quantities of PFAS may result in elevated concentrations in the
environment, EPA believes it would be inappropriate to allow a
reporting option that would exclude information on some releases. Thus,
removing the availability of the use of Form A for PFAS is consistent
with a concern for understanding small quantities of PFAS.
    For TRI-listed chemicals, other than chemicals of special concern,
releases and off-site transfers for further waste management of less
than 1,000 pounds can be reported using ranges or as a whole number.
The reporting ranges are: 1-10 pounds; 11-499 pounds; and 500-999
pounds. For larger releases and offsite transfers for further waste
management of the toxic chemical, the facility must report the whole
number. Use of ranges could reduce data accuracy because the low or the
high-end range numbers may not be that close to the estimated value,
even taking into account inherent data errors (i.e., errors in
measurements and developing estimates). For PFAS, it is important to
have accurate data regarding the amount released even when the
quantities are relatively small, since concern may be tied to even
small quantities of a substance. This issue was apparent for PFAS for
reporting year 2020 since much of the data reported was for less than
1,000 pounds.
    EPA anticipates that the elimination of these burden reduction
tools will increase the amount and quality of data collected for PFAS
and is consistent with the concern for small quantities of PFAS (Ref.
1).

B. Elimination of the Supplier Notification Requirement De Minimis
Exemption for Chemicals of Special Concern

    EPA is also proposing to eliminate the use of the de minimis
exemption under the Supplier Notification Requirements at 40 CFR
372.45(d)(1) for all substances on the list of chemicals of special

concern. EPA extended the de minimis exemption to the supplier
notification requirement in its initial TRI reporting rule (February
16, 1988, 53 FR 4500) (FRL-3298-2). The revised text would read as
follows:

    If a mixture or trade name product contains no toxic chemical in
excess of the applicable de minimis concentration as specified in 40
CFR 372.38(a) except for chemicals listed under 40 CFR 372.28 which
are excluded from the de minimis exemption.

    The de minimis exemption to the Supplier Notification Requirements
allows suppliers to not provide notifications for mixtures or trade
name products containing the listed toxic chemicals if the chemicals
are present at concentrations below 1% of the mixture (0.1% for
carcinogens). The de minimis exemption is not a small quantity
exemption, it is a small concentration exemption. Therefore, it is
possible that significant quantities of chemicals of special concern
can be overlooked by reporting facilities if suppliers can use the de
minimis exemption. For example, if a mixture or trade name product
contains 0.9% of a listed PFAS and 100,000 pounds of the product is
purchased, the supplier need not provide notification and the purchaser
could be unaware of and not account for 900 pounds of PFAS. The impact
of this exemption for the PBT chemicals with 10-pound reporting
thresholds is even greater. Using the same 100,000-pound example, if
mercury were present at 0.9% then that same 900 pounds would be 90
times the mercury reporting threshold.
    It is also possible that quantities of chemicals of special concern
would be included in supplier notifications by reporting facilities if
suppliers cannot use the de minimis exemption. For example, if a
mixture or trade name product contains 0.9% of a listed PFAS and 1,000
pounds of the product is purchased, the supplier would need to provide
notification for 9 pounds of PFAS. This would also impact PBT chemicals
with 10-pound reporting thresholds. Using the same 1,000-pound example,
if mercury was present at 0.9% then that same 9 pounds would be below
the mercury reporting threshold. However, such quantities may become
reportable, in aggregate, if a reporting entity receives multiple
shipments (including from multiple suppliers) of a given product in a
year and performs a threshold activity in excess of the TRI reporting
threshold. Further, TRI supplier notification regulations do not
require a person to consider the total quantity of the chemical being
supplied but rather require the person to consider the concentration of
the chemical in the product or mixture. Including a consideration of
quantity rather than concentration shipped would complicate as well as
reduce the ability of supplier notifications to inform downstream
recipients of products and mixtures containing a TRI-listed chemical.
    EPA considered whether to include a small quantity exemption in
lieu of a de minimis exemption for supplier notification. However, EPA
is concerned that such an exemption would not provide adequate
information to facilities receiving multiple shipments over the course
of a year to address TRI reporting requirements that may apply to them,
based on the total aggregated quantity received. Without such
information on the TRI-listed chemical, the receiving facility may not
have sufficient data to inform potential TRI reporting obligations.
    Many PFAS are used in products below the established de minimis
levels (Refs. 4 and 7) which results in users of those products not
knowing they are receiving a product that contains a TRI reportable
PFAS. PFAS reports received for the TRI 2020 reporting year were mostly
from manufacturers and waste disposal facilities which suggests that
the de minimis exemption may have been used by most users and
processors (https://www.epa.gov/toxics-release-inventory-tri-program/find-understand-and-use-tri). EPA has concluded that it is important
and necessary to eliminate the supplier notification de minimis
exemption for PFAS added to the TRI list pursuant to sections 7321(b)
and 7321(c) of the NDAA because if that exemption were to remain in
place the Agency may fail to collect information on amounts of PFAS
that significantly exceed the reporting threshold.
    In addition, eliminating the use of the de minimis exemption for
supplier notification purposes for all other chemicals of special
concern will ensure that potentially significant quantities of such
chemicals do not get overlooked by reporting facilities. The PBT
chemicals and chemical categories that are classified as chemicals of
special concern, and thus would also be impacted by this change, are as
follows:
     Aldrin (CASRN: 309-00-2);
     Benzo[g,h,i]perylene (CASRN: 191-24-2);
     Chlordane (CASRN: 57-74-9);
     Dioxin and dioxin-like compounds category (manufacturing;
and the processing or otherwise use of dioxin and dioxin-like compounds
category if the dioxin and dioxin-like compounds are present as
contaminants in a chemical and if they were created during the
manufacturing of that chemical) (TRI Category Code: N150);
     Heptachlor (CASRN: 76-44-8);
     Hexabromocyclododecane category (TRI Category Code: N270);
     Hexachlorobenzene (CASRN: 118-74-1);
     Isodrin (CASRN: 465-73-6);
     Lead (this lower threshold does not apply to lead when it
is contained in stainless steel, brass or bronze alloy) (CASRN: 7439-
92-1);
     Lead compounds category (TRI Category Code: N420);
     Mercury (CASRN: 7439-97-6);
     Mercury compounds category (TRI Category Code: N458);
     Methoxychlor (CASRN: 72-43-5);
     Octachlorostyrene (CASRN: 29082-74-4);
     Pendimethalin (CASRN: 40487-42-1);
     Pentachlorobenzene (CASRN: 608-93-5);
     Polychlorinated biphenyls (CASRN: 1336-36-3);
     Polycyclic aromatic compounds category (PACs) (TRI
Category Code: N590);
     Tetrabromobisphenol A (CASRN: 79-94-7);
     Toxaphene (CASRN: 8001-35-2); and
     Trifluralin (CASRN: 1582-09-8).
    When EPA established the chemical of special concern list, it
decided to not remove the de minimis exemption eligibility from
supplier notification requirements, indicating that the Agency believed
that there was sufficient information available on PBT chemicals by
suppliers. See 64 FR 688 (at 715), January 5, 1999 (FRL-6032-3) and 64
FR 58666 (at 58732), October 29, 1999 (FRL-6389-11). However, EPA has
determined that there are situations where this information is not
available. For example, the agency has found that there is significant
variability in the concentration of PACs in fuels, yet the presence and
concentration of PACs in fuel oil is often not provided in supplier
notifications or SDSs. Additionally, EPA is aware of metal mixtures and
products containing low concentrations of lead (not contained in
stainless steel, brass or bronze alloys) whose supplier notifications
and SDSs do not state there is lead present in the mixture or product.
Further, it is unclear whether downstream purchasers would be made
aware of PBT chemicals contained in many products without notification
of the presence of such chemicals.
    In situations where such information is already available, supplier
notifications may already be addressed (e.g., if such information in
already included on an SDS) or the anticipated

burden of a supplier to provide such information would be minimal
(i.e., if the information is redundant then the burden to provide such
known information should be trivial). However, as noted above, the
quantity information EPA proposes to require for de minimis
concentrations below the concentration threshold may not be provided in
SDSs. OSHA maintains a 1 percent concentration threshold for reporting
the presence and concentration of most hazardous chemicals on SDSs. (29
CFR part 1910, subpart Z.) For chronic hazards (with Carcinogenicity,
Germ Cell Mutagenicity, and Reproductive Toxicity), OSHA has
established a 0.1 percent concentration threshold for reporting the
presence and concentration of chemicals on SDSs (29 CFR part 1910,
subpart Z.) EPA notes that there may be other reasons for a chemical's
exclusion from an SDS, including that a chemical's hazard may not be
covered by OSHA, or a chemical may be in an article that is not covered
by SDS requirements. EPA believes that any potential increase in new
supplier reporting is minimal, particularly regarding non-PFAS
chemicals of special concern, but seeks comments on whether new
supplier notifications will need to be developed under this proposal,
and on any associated impacts.
    In the 1999 proposal to establish a chemical of special concern
list, EPA also reasoned that entities subject to TRI supplier
notification requirements could retain use of the de minimis exemption
for PBTs because ``[m]any of the chemicals identified as persistent and
bioaccumulative in today's action are not imported, processed, or
otherwise used but are manufactured as byproducts.'' (64 FR 715;
January 5, 1999). However, the Agency has since learned that several
PBT chemicals are not manufactured as byproducts, and those chemicals
are known to be processed for distribution to customers. For example,
in Reporting Year 2021, the Agency received 55 Form Rs for
tetrabromobisphenol A (TBBPA). None of those forms indicated that TBBPA
had been manufactured as a byproduct. However, some forms indicated the
TBBPA is processed, including as an article component. Similarly, for
Reporting Year 2021, the Agency received 76 Form Rs on polychlorinated
biphenyls (PCBs); 64 of those forms did not indicate those PCBs had
been manufactured as byproducts, though some forms indicated the PCBs
had been processed, including as an article component. Because many PBT
chemicals are not manufactured as byproducts and may exist in
relatively lower concentrations within products or mixtures, the
Agency's initial rationale to allow suppliers to exempt concentrations
of PBT chemicals below de minimis from supplier notification
requirements warrants reconsideration. Therefore, EPA is reassessing
this exemption and modifying it appropriately to provide TRI facilities
with additional information related to quantities of chemicals of
special concern that may contribute to their reporting thresholds. EPA
has concluded that it is important and necessary to eliminate the
supplier notification de minimis exemption for all chemicals of special
concern because if that exemption were to remain in place the Agency
may fail to collect information on amounts of such chemicals that
significantly exceed the reporting threshold.
    This proposed action reflects EPA's current understanding of
chemical activities involving all chemicals of special concern (i.e.,
both PBTs and PFAS).)
    Further, as explained above, EPA's understanding is that downstream
purchasers of products may lack information on the presence of PFAS in
such products. EPA considered limiting the de minimis exception to just
PFAS, but creating a patchwork reporting scheme where the de minimis
exemption is available for supplier notification purposes for certain
chemicals of special concern but not other chemicals of special
concern, or pursuant to some other unique TRI reporting designation,
would create an unnecessary patchwork of reporting requirements that
would unnecessarily complicate supplier notification and TRI reporting
requirements. EPA requests comment on the proposal to remove the de
minimis eligibility from the supplier notification for all chemicals of
special concern and seeks specific information related to the burden
and benefits of this proposed change.

C. Impact of the Proposed Listing of Certain PFAS to the Chemical of
Special Concern List

    The proposed regulatory text would add PFAS currently on TRI
pursuant to 7321(b) and 7321(c) of the NDAA to the list of chemicals of
special concern. Additionally, the proposed regulatory text would
provide that all PFAS added to TRI pursuant to sections 7321(b) and
7321(c), regardless of the date of their addition, will be included on
the chemicals of special concern list. Thus, as PFAS continue to be
added to TRI pursuant to sections 7321(b) and 7321(c), they will also
be added to the list of chemicals of special concern as of the date
they are added to the TRI. This includes substances that meet the
criteria pursuant to 7321(b) and 7321(c) but are claimed confidential,
and the Agency must follow the process outlined in section 7321(e) of
the NDAA to address the claim of confidentiality.
    As with PFAS currently on the TRI list, future PFAS added to the
TRI list under 7321(b) and 7321(c) will have a 100-pound reporting
threshold, per sections 7321(b)(2)(A) and 7321(c)(2)(B). Congress' use
of this low reporting threshold demonstrates a concern for even
relatively small quantities of these PFAS. Therefore, EPA has concluded
that it is appropriate for all PFAS added to the TRI list under these
provisions to be added to the chemicals of special concern list upon
listing. If these PFAS were not added to the chemicals of special
concern list at the time of their addition to the TRI list, there would
be a delay in the reporting requirements while EPA conducts a
rulemaking simply to add them to the chemicals of special concern list.
This would result in differences in how previously listed PFAS and
newly listed PFAS are treated even though they were automatically
listed with the same reporting thresholds. EPA is proposing regulatory
text that would add those PFAS added pursuant to 7321(b) and 7321(c) to
the chemicals of special concern list upon their addition to the TRI
list. EPA requests comment on whether the addition of these PFAS to the
chemicals of special concern list should occur upon addition to the TRI
list and on the proposed regulatory text.
    EPA is not proposing a definition of PFAS as part of this
rulemaking. This rulemaking only concerns chemical substances added to
the TRI by sections 7321(b) and 7321(c) of the NDAA, neither of which
require EPA to provide a definition of PFAS. Section 7321(b) added by
name and/or CASRN specific PFAS to the TRI list and sections 7321(b)
and (c) identify EPA activities involving PFAS that would cause a PFAS
to be added to the TRI list. The activities described by sections
7321(b) and (c) indicate whether they pertain to a PFAS, and thus a
separate determination of whether or not the covered activity involves
a PFAS is not necessary. EPA is therefore not proposing a definition of
PFAS for purposes of this rulemaking, and issues relating to the
definition of PFAS are outside the scope of this rulemaking. EPA
requests comment on EPA's interpretation that a definition is
unnecessary to this rulemaking. EPA will consider the need for a PFAS

definition for a purpose other than the NDAA section 7321(b) and (c)
listings, should the need for such a definition arise.

D. Alternative Mechanisms for PFAS To Be Added to the Chemicals of
Special Concern List

    PFAS may be added to TRI via methods other than NDAA sections
7321(b) and (c) and this proposal does not address whether PFAS added
through such alternative methods should be listed as chemicals of
special concern. For example, any PFAS added via section 7321(d)(3) of
the NDAA would not be impacted by the regulatory text proposed here.
Unlike sections 7321(b) and 7321(c) of the NDAA, Congress did not
establish a reporting threshold of 100 pounds for substances added via
section 7321(d)(3) of the NDAA. EPA will consider whether it is
appropriate to identify these substances as chemicals of special
concern when it takes action to add such substances under section
7321(d)(3) of the NDAA.

V. Statutory and Executive Orders Reviews

    Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders#influence.

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is a significant regulatory action that was submitted
to the Office of Management and Budget (OMB) for review under Executive
Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821,
January 21, 2011). Any changes made in response to OMB recommendations
have been documented in the docket. EPA prepared an economic analysis
of the potential costs and benefits associated with this action. This
analysis (Ref. 1) is available in the docket and summarized in Unit
I.E.

B. Paperwork Reduction Act (PRA)

    The new information collection activities in this proposed rule
have been submitted for approval to OMB under the PRA, 44 U.S.C. 3501
et seq. The information Collection Request (ICR) document that EPA
prepared is assigned EPA ICR No. 2724.01 (Ref. 9). You can find a copy
of the ICR in the docket for this rule, and it is briefly summarized
here.
    Currently, the facilities subject to the reporting requirements
under EPCRA section 313 and PPA section 6607 may use either EPA Toxic
Chemicals Release Inventory Form R (EPA Form 1B9350-1), or EPA Toxic
Chemicals Release Inventory Form A (EPA Form 1B9350- 2). The Form R
must be completed if a facility manufactures, processes, or otherwise
uses any listed chemical above threshold quantities and meets certain
other criteria. For the Form A, EPA established an alternative
threshold for facilities with low annual reportable amounts of a listed
toxic chemical. A facility that meets the appropriate reporting
thresholds, but estimates that the total annual reportable amount of
the chemical does not exceed 500 pounds per year, can take advantage of
an alternative manufacture, process, or otherwise use threshold of 1
million pounds per year of the chemical, provided that certain
conditions are met, and submit the Form A instead of the Form R. In
addition, respondents may designate the specific chemical identity of a
substance as a trade secret pursuant to EPCRA section 322 (42 U.S.C.
11042) and 40 CFR part 350. OMB has approved the reporting and
recordkeeping requirements related to Forms A and R, supplier
notification, and petitions under OMB Control number 2070-0212 (EPA ICR
No. 2613.04) and those related to trade secret designations under OMB
Control 2050-0078 (EPA ICR No. 1428). As such, this ICR is intended to
amend the existing ICR to include the following additional details:
     Respondents/affected entities: Facilities covered under
EPCRA section 313 that manufacture, process or otherwise use listed
PFAS (See Unit I.A.).
     Respondent's obligation to respond: Mandatory (EPCRA
section 313).
     Estimated number of respondents: 605 to 1,997.
     Frequency of response: Annual.
     Total estimated burden: 45,363 and 149,737 burden hours in
the first year and approximately 21,602 and 71,303 burden hours in the
steady state. Burden is defined at 5 CFR 1320.3(b).
     Total estimated cost: Approximately $3,064,271 and
$10,114,734 in the first year of reporting and approximately $1,459,215
and $4,816,518 in the steady state.
    An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for the EPA
regulations in 40 CFR are listed in 40 CFR part 9.
    Submit your comments on the Agency's need for this information, the
accuracy of the provided burden estimates, and any suggested methods

for minimizing respondent burden to the EPA using the docket identified
at the beginning of this proposed rule. You may also send your ICR-
related comments to OMB's Office of Information and Regulatory Affairs
using the interface at https://www.reginfo.gov/public/do/PRAMain. Find
this particular information collection by selecting ``Currently under
Review--Open for Public Comments'' or by using the search function.
Since OMB is required to make a decision concerning the ICR between 30
and 60 days after receipt, OMB must receive comments no later than
January 4, 2023. EPA will respond to any ICR-related comments in the
final rule.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA, 5
U.S.C. 601 et seq. The small entities subject to the requirements of
this action are primarily classified within the manufacturing and waste
management industry sectors. The Agency has determined that of the 605
to 1,997 entities estimated to be impacted by this action, 467 to 1,313
are small businesses; no small governments or small organizations are
expected to be affected by this action. The average cost per small firm
is $2,714 (at a 3% discount rate) or $2,765 (at a 7% discount rate).
The total cost for small entities is $1,267,363-$3,563,272 (at a 3%
discount rate) or $1,291,213-$3,630,327 (at a 7% discount rate). All
small businesses affected by this action are estimated to incur
annualized cost impacts of less than 1%. Even under a worst-case
scenario comparing compliance costs to average revenue of firms with
between 10 (smallest number required to report) and 14 employees
instead of comparing compliance costs to the weighted average revenue
of small firms, there are still no costs that exceed the 1% impact
threshold. Thus, this action is not expected to have a significant
adverse economic impact on a substantial number of small entities. A
more detailed analysis of the impacts on small entities is provided in
EPA's economic analysis (Ref. 1).

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or
more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. This action is not
subject to the requirements of UMRA because it contains no regulatory
requirements that might significantly or uniquely affect small
governments. EPA did not identify any small governments that would be
impacted by this action. EPA's economic analysis indicates that the
total cost of this action is estimated to be from $3,064,271 and
$10,114,734 in the first year of reporting and from $1,459,215 and
$4,816,518 in subsequent reporting years (Ref. 1).

E. Executive Order 13132: Federalism

    This action does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999). It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action does not have Tribal implications as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). This action
relates to toxic chemical reporting under EPCRA section 313, which
primarily affects private sector facilities. Thus, Executive Order
13175 does not apply to this action.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997)
as applying only to those regulatory actions that concern environmental
health or safety risks that EPA has reason to believe may
disproportionately affect children, per the definition of ``covered
regulatory action'' in section 2-202 of the Executive Order. This
action is not subject to Executive Order 13045 because it does not
concern any environmental health risks or safety risks.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

    This action is not a ``significant energy action'' as specified in
Executive Order 13211 (66 FR 28355, May 22, 2001) because it is not
likely to have a significant adverse effect on the supply, distribution
or use of energy and has not otherwise been designated by the
Administrator of the Office of Information and Regulatory Affairs as a
significant energy action.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards. As such,
NTTAA section 12(d), 15 U.S.C. 272 note, does not apply to this action.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) directs
Federal agencies, to the greatest extent practicable and permitted by
law, to make environmental justice part of their mission by identifying
and addressing, as appropriate, disproportionately high and adverse
human health or environmental effects of their programs, policies, and
activities on minority populations (people of color) and low-income
populations.
    The EPA believes that this type of action does not directly concern
human health or environmental conditions and therefore cannot be
evaluated with respect to potentially disproportionate and adverse
effects on people of color, low-income populations and/or indigenous
peoples. This regulatory action makes changes to the reporting
requirements for PFAS that will result in more information being
collected and provided to the public; it does not have any direct
impact on human health or the environment. This action does not address
any human health or environmental risks and does not affect the level
of protection provided to human health or the environment. This action
makes changes to the reporting requirements for PFAS which will provide
more information on releases and waste management of PFAS. By requiring
reporting of this additional information, EPA would be providing
communities across the U.S. (including minority populations and low-
income populations) with access to data which they may use to seek
lower exposures and consequently reductions in chemical risks for
themselves and their children. This information can also be used by
government agencies and others to identify potential problems, set
priorities, and take appropriate steps to reduce any potential risks to
human health and the environment. Therefore, the informational benefits
of the action will have a positive impact on the human health and
environmental impacts of minority populations, low-income populations,
and indigenous peoples.
