Long-Chain Perfluoroalkyl Carboxylate and Perfluoroalkyl
Sulfonate Chemical Substances; Significant New Use Rule
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: Under the Toxic Substances Control Act (TSCA), the
Environmental Protection Agency (EPA) is finalizing amendments to the
significant new use rule (SNUR) for long-chain perfluoroalkyl
carboxylate (LCPFAC) chemical substances that were proposed on January
21, 2015; an amendment to a SNUR for perfluoroalkyl sulfonate chemical
substances that was proposed on January 21, 2015; and an amendment to
make inapplicable the exemption for persons who import a subset of
LCPFAC chemical substances as part of surface coatings on articles,
which was proposed on March 3, 2020. This final rule requires persons
to notify EPA at least 90 days before commencing the manufacture
(including import) or processing of these chemical substances for the
significant new uses described in this notice. The required significant
new use notification initiates EPA's evaluation of the conditions of
use associated with the significant new use. Manufacturing (including
import) or processing for the significant new use are prohibited from
commencing until EPA has conducted a review of the notice, made an
appropriate determination on the notice, and taken such actions as are
required in association with that determination. As with any SNUR, this
final rule excludes ongoing uses. Ongoing uses cannot be subject to a
SNUR.
DATES: This final rule is effective September 25, 2020.

SUPPLEMENTARY INFORMATION:
I. Executive Summary
A. Does this action apply to me?
You may be potentially affected by this action if you manufacture
(including import), process, or distribute in commerce chemical
substances and mixtures in the class of long-chain perfluoroalkyl
carboxylate (LCPFAC) and perfluoroalkyl sulfonate chemical substances.
The following list of North American Industrial Classification System
(NAICS) codes is not intended to be exhaustive, but rather provides a
guide to help readers determine whether this document applies to them.
Potentially affected entities may include:
Manufacturers (including importers) of one or more of
subject chemical substances (NAICS codes 325 and 324110); e.g.,
chemical manufacturing and petroleum refineries.
Fiber, yarn, and thread mills (NAICS code 31311).
Carpet and rug mills (NAICS code 314110).
Home furnishing merchant wholesalers (NAICS code 423220).
Carpet and upholstery cleaning services (NAICS code
561740).
Manufacturers of computer and other electronic products,
appliances, and components (NAICS codes 324 and 335).
Manufacturers of surgical and medical instruments (NAICS
339112).
Merchant wholesalers (NAICS codes 423 and 424).
Stores and retailers (NAICS codes 442, 442, 444, 448, 451,
454).
Providers of other support services (NAICS code 561990).
Other types of entities not listed in this unit could also be
affected. The NAICS codes have been provided to assist you and others
in determining whether this action might apply to certain entities.
This action may affect certain entities through pre-existing import
certification and export notification rules under TSCA. Persons who
import any chemical substance governed by a final SNUR are subject to
the TSCA section 13 (15 U.S.C. 2612) import certification requirements
and the corresponding regulations at 19 CFR 12.118 through 12.127; see
also 19 CFR 127.28. Those persons must certify that the shipment of the
chemical substance complies with all applicable rules and orders under
TSCA, including any SNUR requirements. The EPA policy in support of
import certification appears at 40 CFR part 707, subpart B.
Additionally, persons who export or intend to export a chemical
substance that is the subject of a proposed or final SNUR are subject
to the export notification provisions of TSCA section 12(b) (15 U.S.C.
2611(b); see also 40 CFR part 707, subpart D and 40 CFR 721.20). Under
the existing TSCA import certification and export notification rules,
persons who import a chemical substance covered under this final rule
as part of an article would be exempt from TSCA section 13 import
certification, and persons who export or intend to export a chemical
substance as part of an article would be exempt from the TSCA section
12(b) export notification requirements. See Unit V. for more
information on the applicability of the import certification and export
notification requirements.
If you have any questions regarding the applicability of this
action to a particular entity, consult the technical information
contact listed under FOR FURTHER INFORMATION CONTACT.
B. What is the Agency's authority for taking this action?
TSCA section 5(a)(2) (15 U.S.C. 2604(a)(2)) authorizes EPA to
determine that a use of a chemical substance is a ``significant new
use.'' EPA must make this determination by rule after considering all
relevant factors, including those listed in TSCA section 5(a)(2). TSCA
section 5(a)(2) (15 U.S.C. 2604(a)(2)) states that EPA's determination
that a use of a chemical substance is a significant new use must be
made after consideration of the following factors:
The projected volume of manufacturing and processing of a
chemical substance,
The extent to which a use changes the type or form of
exposure of human beings or the environment to a chemical substance,
The extent to which a use increases the magnitude and
duration of exposure of human beings or the environment to a chemical
substance,
The reasonably anticipated manner and methods of
manufacturing, processing, distribution in commerce, and disposal of a
chemical substance.
In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorizes EPA to consider any other relevant factors. Once
EPA determines that a use of a chemical substance is a significant new
use, TSCA section 5(a)(1)(B)(i) requires persons to submit a
significant new use notice (SNUN) to EPA at least 90 days before they
manufacture (including import) or process the chemical substance for
that use (15 U.S.C. 2604(a)(1)(B)(i)). TSCA furthermore prohibits such
manufacturing or processing from commencing until EPA has conducted a
review of the notice, made an appropriate determination on the notice,
and taken such actions as are required in association with that
determination (15 U.S.C. 2604(a)(1)(B)(ii)). Additionally, TSCA section
5(a)(5) (15 U.S.C. 2604(a)(5)), as amended in 2016, authorizes EPA to
require notification for the import or processing of a chemical
substance as part of an article or category of articles under TSCA
section 5(a)(1)(A)(ii) (15 U.S.C. 2604(a)(1)(A)(ii)) if EPA makes an
affirmative finding in a rule under TSCA section 5(a)(2) (15 U.S.C.
2604(a)(2)) that the reasonable potential for exposure to the chemical
substance through the article or category of articles subject to the
rule justifies notification. As described in Unit V., the general SNUR
provisions are found at 40 CFR part 721, subpart A.
C. What action is the Agency taking?
In the Federal Register of January 21, 2015 (80 FR 2885) (FRL-9915-
63), EPA proposed a SNUR for Long-Chain Perfluoroalkyl Carboxylate and
Perfluoroalkyl Sulfonate Chemical Substances (Ref. 1). In the Federal
Register of March 3, 2020 (85 FR 12479) (FRL-10003-21) (Ref. 2), EPA
supplemented the 2015 proposed SNUR to be responsive to the article
consideration provision at section 5(a)(5), added with the passage of
the Frank R. Lautenberg Chemical Safety for the 21st Century Act
(Lautenberg Act), which states that articles can be subject to
notification requirements as a significant new use provided that EPA
makes an affirmative finding in a rule that the reasonable potential
for exposure to a chemical from an article or category of articles
justifies notification.
[[Page 45111]]
EPA's response to public comments received on both the 2015
proposed rule and the 2020 supplemental proposed rule are provided in a
Response to Comments document that is available in the docket and
summarized in Unit XII. (Ref. 3). Please consult the Federal Register
documents of January 21, 2015 (Ref. 1) and March 3, 2020 (Ref. 2) for
further background information for this final rule.
This final SNUR will require persons to notify EPA at least 90 days
before commencing:
1. The manufacturing (including importing) or processing of a
subset of LCPFAC chemical substances for any use that was not ongoing
after December 31, 2015;
2. The manufacturing (including importing) or processing of all
other LCPFAC chemicals substances for which there were no ongoing uses
as of January 21, 2015 (the date of the original 2015 proposal);
3. The import of a subset of LCPFAC chemicals as part of a surface
coating on articles; and
4. The import of perfluoroalkyl sulfonate chemical substances as
part of carpets.
This final SNUR will preclude the commencement of such
manufacturing and processing until EPA has conducted a review of the
notice, made an appropriate determination on the notice, and taken such
actions as are required in association with that determination.
In the Federal Register of April 24, 1990 (55 FR 17376; FRL-3658-
5), EPA decided that the intent of TSCA section 5(a)(1)(B) is best
served by designating a use as a significant new use as of the date of
publication of the proposed rule rather than as of the effective date
of the final rule. Uses arising after the publication of the proposed
rule are distinguished from uses that exist at publication of the
proposed rule. The former would be new uses, the latter would be
ongoing uses, except that uses that are ongoing as of the publication
of the proposed rule would not be considered ongoing uses if they have
ceased by the date of issuance of a final rule. This rule was published
on January 21, 2015 and contains two significant new use dates. The
first significant new use date is the date that the 2015 proposed rule
published and applies to: The manufacturing or processing of all LCPFAC
chemicals substances, other than those listed in the list of LCPFAC
chemical substances in Unit II.; the import of articles containing a
subset of LCPFAC chemical substances as part of a surface coating; and
the import of perfluoroalkyl sulfonate chemical substances as part of
carpets. The second significant new use date is December 31, 2015, for
the manufacturing or processing of a subset of LCPFAC chemical
substances, those listed in the list of LCPFAC chemical substances in
Unit II. for any use. The chemical substances listed in the list of
LCPFAC chemical substances in Unit II. correspond to the chemical
substances that the principal manufacturers and processors of LCPFAC
chemical substances participating in the 2010/2015 PFOA Stewardship
Program agreed to phaseout by the end of 2015. Ongoing uses are
described in the Response to Comment for this rule (Unit XII. and Ref.
3) and are reflected in updates to the regulatory text.
In the supplement to the proposed rule (Ref. 2), EPA requested
comment on whether EPA could adopt a de minimis threshold for
determining ``reasonable potential for exposure'' and if so, how that
de minimis threshold could be established. Additionally, EPA requested
comment on whether or not the Agency should include a safe harbor
provision for importers of articles that can demonstrate their use was
ongoing prior to the effective date of this rule. EPA appreciates the
comments received. In this final rule, EPA is not finalizing a de
minimis threshold for determining ``reasonable potential for exposure''
or a safe harbor provision. EPA will, however, continue to engage with
interested stakeholders on these two issues. A further discussion of
the comments received relating to a de minimis threshold and a safe
harbor provision are included in the Response to Comment for this rule
(Unit XII. and Ref. 3).
D. Why is the Agency taking this action?
These SNUR amendments are necessary to ensure that EPA receives
timely advance notice of any future manufacturing (including importing)
and processing of LCPFAC and perfluoroalkyl sulfonate chemical
substances for new uses that may produce changes in human and
environmental exposures. Additionally, section 7352 of the National
Defense Authorization Act of 2020 mandates that EPA take final action
on the 2015 proposal no later than June 22, 2020.
The rationale and objectives for this rule are explained in Unit
III.
E. What are the estimated incremental impacts of this action?
EPA has evaluated the potential costs of establishing SNUR
reporting requirements for potential manufacturers (including
importers) and processors of the chemical substances included in this
final rule. This Economic Analysis (Ref. 4), which is available in the
docket, is discussed in Unit IX., and is briefly summarized here.
In the event that a SNUN is submitted, costs are estimated to be
approximately $23,000 per SNUN submission for large business submitters
and about $10,000 for small business submitters. The rule may also
affect firms that plan to import articles that may be subject to the
SNUR. Although there are no specific requirements in the rule for these
firms, they may choose to undertake some activity to assure themselves
that they are not undertaking a significant new use. In the
accompanying Economic Analysis for this SNUR (Ref. 4), EPA provides
example steps (and their respective costs) that an importer might take
to identify LCFPAC chemical substances in articles. These can include
gathering information through agreements with suppliers, declarations
through databases or surveys, or use of a third-party certification
system. EPA is unable to predict, however, what, if any, particular
steps an importer might take; thus, potential total costs were not
estimated. Importers may require suppliers to provide certificates of
testing analysis of the products or perform their own laboratory
testing of certain articles. An estimate of article testing cost is
provided in Exhibit 3-7 of the Economic Analysis. While testing costs
will vary depending on the specific chemical being tested for, the
complexity of the article and sample preparation required, and the
exact fees of the laboratory chosen for the analysis, an average of
$150 per article tested is given in the Exhibit.
II. Chemical Substances Subject to This Rule
This final SNUR modifies the requirements for a subset of LCPFAC
chemical substances in the existing SNUR at 40 CFR 721.10536 by:
1. Designating manufacturing (including importing) or processing of
LCPFAC chemical substances listed in the list of LCPFAC chemical
substances in this unit for any use that was no longer ongoing after
December 31, 2015, as a significant new use; and
2. Designating manufacturing (including importing) or processing of
perfluorooctanoic acid (PFOA) or its salts, which are considered LCPFAC
chemical substances, and all other LCPFAC chemical substances for any
use not ongoing as of January 21, 2015, the date on which the proposed
rule was published, as a significant new use.
For this final SNUR, EPA is also making the exemption at 40 CFR
[[Page 45112]]
721.45(f) inapplicable for persons who import LCPFAC chemical
substances listed in the list of LCPFAC chemical substances in this
unit and PFOA or its salts (see examples in this unit) as part of a
surface coating on articles because there is reasonable potential for
exposure to LCPFAC chemical substances, including PFOA, if these
chemical substances are incorporated as surface coatings in articles
and then imported. As was originally proposed in 2015, the article
exemption still applies to LCPFAC chemical substances not listed in
this unit or that are not PFOA or its salts, with the exception of the
import of carpets, for which the import exemption is already
inapplicable (78 FR 62443, October 22, 2013; FRL-9397-1). The other
provision of 40 CFR 721.45(f), respecting processing a chemical
substance as part of an article, remains applicable. These LCPFAC
chemical substances are:

The term LCPFAC refers to the long-chain category of perfluorinated
carboxylate chemical substances with perfluorinated carbon chain
lengths equal to or greater than seven carbons and less than or equal
to 20 carbons. The category of LCPFAC chemical substances also includes
the salts and precursors of these perfluorinated carboxylates. See Unit
II.A. of the 2015 proposed rule (Ref. 1) for further discussion of the
LCPFAC category. In addition to the subset of LCPFAC chemical
substances identified in the list above, PFOA and its salts are subject
to the final rule. PFOA and its salts are considered LCPFAC chemical
substances. PFOA and examples of PFOA salts with CASRNs and chemical
names are as follows:
Pentadecafluorooctanoyl fluoride (CASRN 335-66-0; TSCA
Chemical Inventory Name: Octanoyl fluoride,
2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluoro-).
Perfluorooctanoic acid (CASRN 335-67-1; TSCA Chemical
Inventory Name: Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-
pentadecafluoro- (PFOA)).
Silver perfluorooctanoate (CASRN 335-93-3; TSCA Chemical
Inventory Name: Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-
pentadecafluoro-, silver (+) salt (1:1)).
Sodium perfluorooctanoate (CASRN 335-95-5; TSCA Chemical
Inventory Name: Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-
pentadecafluoro-, sodium salt (1:1)).
Potassium perfluorooctanoate (CASRN 2395-00-8; TSCA
Chemical Inventory Name: Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-
pentadecafluoro-, potassium salt (1:1)).
Ammonium perfluorooctanoate (CASRN 3825-26-1; TSCA
Chemical Inventory Name: Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-
pentadecafluoro-, ammonium salt (1:1) (APFO).
EPA is also amending the existing SNUR at 40 CFR 721.9582 for
perfluoroalkyl sulfonate chemical substances to make the exemption at
40
[[Page 45113]]
CFR 721.45(f) inapplicable for persons who import perfluoroalkyl
sulfonate chemical substances as part of carpets, which is being
finalized as proposed. The perfluoroalkyl sulfonate chemical substances
for which EPA is modifying an existing SNUR are currently listed in 40
CFR 721.9582(a)(1). In this rule, which is consistent with the proposal
and 40 CFR 721.9582, the term perfluoroalkyl sulfonates refers to a
category of perfluorinated sulfonate chemical substances of any chain
length. In the 2015 proposed rule, as was past practice, perfluoroalkyl
sulfonates chemical substances were referred to as ``PFAS'' chemical
substances. EPA, however, recognizes that the acronym PFAS is now used
for ``perfluoroalkyl and polyfluoroalkyl substances.'' Moving forward,
EPA will use PFAS as an acronym for perfluoroalkyl and polyfluoroalkyl
substances.
III. Rationale and Objectives
A. Rationale
1. Known Exposures to LCPFAC and Perfluoroalkyl Sulfonate Substances
LCPFAC and perfluoroalkyl sulfonate chemical substances have been
found in the blood of the general human population, as well as in
wildlife, indicating that exposure to these chemical substances is
widespread (Refs. 5, 6, and 7). PFOA and its salts, which are
considered LCPFAC chemical substances, have been a primary focus of
studies related to the LCPFAC class of chemical substances. PFOA is
persistent, widely present in humans and the environment, has a half-
life in humans of 2.3-3.8 years, and can cause adverse effects in
laboratory animals, including cancer and developmental and systemic
toxicity (Refs. 5, 8, 9, 10, and 11). Human epidemiology data report
associations between PFOA exposure and high cholesterol, increased
liver enzymes, decreased vaccination response, thyroid disorders,
pregnancy-induced hypertension and preeclampsia, and cancer (testicular
and kidney) (Ref. 12). PFOA precursors, chemicals which degrade or may
degrade to PFOA, are also present worldwide in humans and the
environment and, in some cases, might be more toxic and be present at
higher concentrations than PFOA (Refs. 13, 14, 15, 16, and 17).
Multiple pathways of exposure, including through drinking water, food,
house dust, and release from treated articles, are possible (Ref. 18).
Perfluoroalkyl sulfonate chemical substances degrade ultimately to
perfluoroalkylsulfonic acid (PFASA), which can exist in the anionic
form under certain environmental conditions (Ref. 15). PFASA is highly
persistent in the environment and has a tendency to bioaccumulate (Ref.
15). While most studies of perfluoroalkyl sulfonate chemical substances
to date have focused primarily on perfluorooctane sulfonate (PFOS),
structure-activity relationship analysis indicates that the results of
those studies are applicable to the entire category. Available test
data have raised concerns about their potential developmental,
reproductive, and systemic toxicity (Refs. 5, 6, 13, and 19).
In the absence of a regulation, manufacture or processing for the
significant new uses proposed on January 21, 2015 (Ref. 1), may begin
at any time, without prior notice to EPA. As explained in the January
21, 2015, proposal (Ref. 1), EPA is concerned that commencement of the
manufacture or processing for any new uses, including resumption of
past uses, of LCPFAC and perfluoroalkyl sulfonate chemical substances
could increase the magnitude and duration of exposure to humans and the
environment.
The manufacture of LCPFAC chemical substances listed in Unit II.
was discontinued after December 31, 2015, as committed by the principal
manufacturers and processors of LCPFAC chemical substances
participating in the 2010/2015 PFOA Stewardship Program. Given that
these chemical substances have been discontinued, EPA expects the
presence of LCPFAC chemical substances in humans and the environment to
decline over time as has been observed in the past when production and
use of other persistent chemicals have ceased (Ref. 20). At this time,
EPA is aware, and has provided an exemption for, the processing of
select chemical substances listed in Unit II. that continues from the
use of existing stocks for specific uses. The processing of existing
stocks of these LCPFAC chemical substances is expected to decline over
time as stocks of these chemicals are depleted. Similarly, EPA also
expects ongoing uses of other LCPFAC chemicals substances to decline
because the manufacture and processing for those uses have declined or
ceased, as indicated by industry communication, market research,
information submitted to EPA under the Chemical Data Reporting (CDR)
rule, and comments received related to the proposed rule (Ref. 1) and
supplement to the proposed rule (Ref. 2). In addition, EPA expects the
presence of perfluoroalkyl sulfonate chemical substances to decline in
humans and the environment because perfluoroalkyl sulfonates are no
longer imported as part of carpets. EPA is concerned that the
manufacturing or processing of these chemical substances for
significant new uses could be reinitiated in the future. If
reinitiated, EPA believes that such use could significantly increase
the magnitude and duration of exposure to humans and the environment to
these chemical substances.
2. Identification of Significant New Uses
Consistent with EPA's past practice for issuing SNURs under TSCA
section 5(a)(2), EPA's decision to propose a SNUR for a particular use
of a chemical substance is not based on an extensive evaluation of the
hazard, exposure, or potential risk associated with that use. Rather,
EPA's determination that a use constitutes a significant new use
requires a notice, upon receipt of which EPA would conduct an
assessment. If a person decides to begin manufacturing or processing
any of these chemicals for a significant new use, the notice to EPA
allows the Agency to evaluate the use according to the specific
parameters and circumstances surrounding the conditions of use.
3. Basis for Lifting the Article Exemption
Enacted on June 22, 2016, the Frank R. Lautenberg Chemical Safety
for the 21st Century Act (Pub. L. 114-182) amended several sections of
TSCA and added section 5(a)(5), Article Consideration, which states
that EPA ``may require notification under this section for the import
or processing of a chemical substance as part of an article or category
of articles'' if EPA affirmatively finds in a rule under section
5(a)(2) that the reasonable potential for exposure to the chemical
substance through the article or category of articles justifies
notification. In the 2015 proposal (Ref. 1), EPA proposed to make the
exemption from notification requirements for persons who import the
chemical substance as part of an article inapplicable for the import of
a subset of LCPFAC chemical substances in ``all'' articles. After
careful consideration, and in order to align the 2015 proposed rule
with the new requirements under TSCA, EPA issued a supplemental
proposal to require submission of a significant new use notice for the
import of a subset of LCPFAC chemical substances ``as part of a surface
coating on articles'' as opposed to ``all articles.'' The supplemental
proposal better defined the articles subject to the rule by defining
the subject articles by the category: ``imported articles where certain
[[Page 45114]]
LCPFAC chemical substances are part of a surface coating on the
articles.'' While the 2020 supplemental and the 2015 proposed SNUR
differ in language, EPA believes that the difference in impact will be
minimal. LCPFAC chemical substances can be applied to articles as a
surface coating. By lifting the articles exemption for articles that
contain certain LCPFAC chemical substances as part of a surface
coating, EPA believes that it has captured the majority of article
applications of these chemical substances. Other than instances where
LCPFAC chemicals may be used to manufacture fluoropolymer membranes,
EPA is unaware of any other uses of LCPFAC chemical substances in
articles other than as a surface coating. EPA may propose future SNURs
for the import of other articles containing LCPFAC chemical substances
as appropriate.
Products such as paints and coatings, lubricants, and fire-fighting
foam are not articles. As defined at 40 CFR 704.3, article means a
manufactured item (1) which is formed to a specific shape or design
during manufacture, (2) which has end use function(s) dependent in
whole or in part upon its shape or design during end use, and (3) which
has either no change of chemical composition during its end use or only
those changes of composition which have no commercial purpose separate
from that of the article, and that result from a chemical reaction that
occurs upon end use of other chemical substances, mixtures, or
articles; except that fluids and particles are not considered articles
regardless of shape or design. Examples of articles that could contain
LCPFAC chemical substances as part of a surface coating include, but
are not limited to, apparel, outdoor equipment, automotive parts,
carpets, furniture, and electronic components.
As detailed in the March 3, 2020 supplemental proposal (Ref. 2),
given that the release of LCPFAC chemical substances from surface
coatings on articles has been shown to occur and that these releases
can reasonably be expected to result in exposure to the users of
articles and the general public (Refs. 21, 22, 23, 24, and 25), EPA has
reason to anticipate that importing articles that have certain LCPFAC
chemical substances as part of a surface coating would create a
reasonable potential for exposure to these LCPFAC chemical substances,
and that EPA should have an opportunity to review the use before such
use could occur. Therefore, in light of the evidence before EPA
(including the studies referenced below), EPA affirmatively finds under
TSCA section 5(a)(5) that notification for import is justified by the
reasonable potential for exposure to certain LCPFAC chemical substances
when part of surface coatings on articles. If a person wants to
recommence a significant new use, existence of the SNUR ensures the
submission of a SNUN, thereby allowing EPA to evaluate potential uses
(before those uses would begin) for any hazards, exposures and risks
that might exist.
During the public comment period for the supplemental proposal
(Ref. 2), several commenters questioned if EPA had adequately shown the
reasonable potential for exposure from articles containing LCPFAC
chemical substances as part of a surface coating or the risks
associated with such potential exposure. One commenter asked that EPA
provide linking data between presence of LCPFAC chemical substances in
the general population and the release of LCPFAC chemical substances
from coatings. EPA believes that the reasonable potential for exposure
has been addressed through the studies cited in both this final rule
and the supplement to the proposed rule (Refs. 2, 5, 23, 25, and 26).
EPA has provided support that there is a reasonable potential for
exposure through the citation of peer-reviewed literature, which
documents that LCPFAC chemical substances either have the reasonable
potential to migrate from articles or that LCPFAC chemical substances
do migrate from articles. In order to require notification for the
import or processing of an article under TSCA section 5, it is not
necessary to definitively show or illustrate the mechanisms by which
exposure to a chemical substance through an article may occur. Since
the use designated as a significant new use does not currently exist,
EPA defers a detailed consideration of potential exposures related to
that use until there is a specific condition of use and data to review.
EPA's standard for an affirmative finding is consistent with the
statutory language requiring a reasonable potential for exposure
(rather than a certainty of exposure.
As stated in the supplemental proposal, a coating is a material
applied in a thin layer to a surface as a protective, decorative, or
functional film. This term often refers to paints such as lacquers or
enamels, but also refers to films applied to other materials including,
but are not limited to, paints, varnishes, sealants, adhesives, inks,
maskants, and temporary protective coatings. During the public comment
period for the 2020 supplemental proposal (Ref. 2), several commenters
asked EPA to define ``surface coating'' and to include a definition in
the regulatory text. EPA does not intend to finalize a regulatory
definition of ``surface coating.'' Rather, EPA will be issuing guidance
within a reasonable timeframe of the final rule. EPA is not defining
this term due to the many different ways that LCPFAC chemical
substances could be applied to an article as part of a surface coating
and how a given article could move through the supply chain from
manufacture to disposal. EPA believes that this approach ensures that
EPA will have the opportunity to conduct a detailed consideration of
potential exposures related to these uses when there is a specific
condition of use to review. If EPA receives a SNUN, EPA will evaluate
the potential releases from the article with information specific to
that article.
Articles that have surface coatings that contain certain LCPFAC
chemical substances that have been cured or undergone chemical reaction
after being applied to an article are subject to this rule. Even when
LCPFAC are bound within the matrix of the coating, they can still be
released from the coating over time and present a reasonable potential
for exposure. These surface coatings have been unambiguously shown to
be a source of LCPFAC in the environment (Refs. 23, 25, 27, and 28),
even when adhered to surfaces in accordance with practices reported in
patents (Refs. 23 and 25), and hence, present the reasonable potential
for exposure to the chemical substance through the category of articles
subject to the rule.
As noted in Unit V. of the proposed rule (Ref.1), EPA is retaining
the exemption at 40 CFR 721.45(f) for persons who process chemical
substances as part of articles because existing stocks of articles
still contain LCPFAC or perfluoroalkyl sulfonate chemical substances.
EPA considers recycling to be a form of processing (Ref. 29). Because
the processing of articles containing LCPFAC or perfluoroalkyl
sulfonate chemical substances is ongoing, it cannot be subject to a
SNUR. If EPA finds reason to believe that the processing of articles
containing LCPFAC or perfluoroalkyl sulfonate chemical substances has
ceased, EPA may issue a future SNUR on the processing of articles that
contain these chemical substances. See Comment-Response 7 in the
Response to Comment document for additional discussion of the ongoing
processing of these chemical substances (Ref. 3).
[[Page 45115]]
B. Objectives
Based on the considerations in Unit III.A., EPA wants to achieve
the following objectives with regard to the significant new uses of
LCPFAC and perfluoroalkyl sulfonate chemical substances that are
designated in the January 21, 2015, proposal (Ref. 1) and the March 3,
2020, supplemental proposal (Ref. 2):
1. EPA would receive notice of any person's intent to manufacture
(including import) or process the chemical substances for the described
significant new use before that activity begins.
2. EPA would have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins manufacturing or
processing the chemical substances for the described significant new
use.
3. EPA would be able to either determine that the significant new
use is not likely to present an unreasonable risk, or to take necessary
regulatory action associated with any other determination, before the
described significant new use of the chemical substance occurs.
IV. Significant New Use Determination
According to TSCA section 5(a)(2), EPA's determination that a use
of a chemical substance is a significant new use must be made after
consideration of all relevant factors, including:
1. The projected volume of manufacturing and processing of a
chemical substance.
2. The extent to which a use changes the type or form of exposure
of human beings or the environment to a chemical substance.
3. The extent to which a use increases the magnitude and duration
of exposure of human beings or the environment to a chemical substance.
4. The reasonably anticipated manner and methods of manufacturing,
processing, distribution in commerce, and disposal of a chemical
substance.
In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorizes EPA to consider any other relevant factors to
determine what would constitute a significant new use of the LCPFAC and
perfluoroalkyl sulfonate chemical substances subject to this final
rule, as discussed in this unit. EPA considered relevant information
about the toxicity of these substances, trends in blood levels, likely
human exposures and environmental releases associated with possible
uses, and the four factors listed in TSCA section 5(a)(2).
As discussed in Unit III.A., since the manufacture (including
import) and processing of LCPFAC and perfluoroalkyl sulfonate chemical
substances for these uses has been discontinued in the United States,
exposure will decrease over time. EPA expects their presence in humans
and the environment to decline over time. If any of the new uses of
LCPFAC and perfluoroalkyl sulfonate chemical substances were to resume
after having been phased out, EPA believes that such uses could both
change the type and form and increase the magnitude and duration of
human and environmental exposure to the substances, constituting a
significant new use. Based on consideration of the statutory factors
discussed herein, EPA has determined the following uses are significant
new uses:
Manufacturing (including importing) or processing of
LCPFAC chemical substances listed in the list of LCPFAC chemical
substances in Unit II. for any use that is no longer ongoing after
December 31, 2015.
Manufacturing (including importing) or processing of PFOA
or its salts for any use not ongoing as of the date on which the
proposed rule was published (Ref. 1).
Manufacturing (including importing) or processing of all
other LCPFAC chemical substances for any use not ongoing as of January
21, 2015, the date on which the proposed rule was published (Ref. 1).
EPA believes any new use of certain LCPFAC chemical substances as
part of a surface coating of an article could increase the duration and
magnitude of human and environmental exposure to the chemical
substances, as discussed in the March 3, 2020, supplement to proposed
SNUR (Ref. 2). Based on these considerations, EPA has determined that:
Importing LCPFAC chemical substances listed in the list of LCPFAC
chemical substances in Unit II. and PFOA or its salts (See Unit I. for
examples of PFOA salts) as part of a surface coating of an article, for
uses not ongoing as of the date on which the 2015 proposed rule was
published (Ref. 1), constitutes a significant new use and warrants
making the exemption at 40 CFR 721.45(f) inapplicable to importers of
such articles.
Evidence supports that there is a reasonable potential for exposure
to the chemical substances subject to this SNUR through their
importation as part of a surface coating of an article. EPA should have
an opportunity to review such uses before they can resume. Persons
subject to this SNUR are required to notify EPA at least 90 days prior
to commencing manufacture (including import) or processing of the
chemical substances for the new use. This required notification
provides EPA with the opportunity to evaluate any intended significant
new use of the regulated chemical substances and, if necessary, an
opportunity to protect against potential unreasonable risks.
EPA has determined that the import of fluoropolymer dispersions and
emulsions and articles containing fluoropolymers in articles is not a
significant new use because, at the time of the 2015 proposed rule, EPA
believed this use to be ongoing and did not propose to include this use
in the SNUR. Ongoing uses cannot be subject to a SNUR. Since proposing
the SNUR in 2015, EPA has received comment that the use fluoropolymer
dispersions and emulsions made with PFOA has ceased. Because EPA did
not propose and take comment on lifting the exemption for the import of
fluoropolymer dispersions and emulsions, and fluoropolymers as part of
articles, EPA has not included it in this final rule. At this time, EPA
is not making inapplicable any of the standard exemptions at 40 CFR
721.45 for fluoropolymer dispersions and emulsions, and fluoropolymers
as part of articles. Yet, EPA may issue a future SNUR on the
manufacture and processing of fluoropolymer dispersions and emulsions
and articles containing fluoropolymers.
In a previous rule (78 FR 62443, October 22, 2013; FRL-9397-1), EPA
designated all uses of the perfluoroalkyl sulfonate chemicals
identified in 40 CFR 721.9582 as significant new uses, except the
ongoing uses specified in 40 CFR 721.9582 (a)(3) through (a)(5). The
Agency has determined that the manufacture (including import) and
processing of any of the perfluoroalkyl sulfonate chemical substances
subject to this rule have been discontinued, including the importing of
these chemical substances as part of carpets. EPA believes any new use
of perfluoroalkyl sulfonate chemicals substances as part of carpets
could increase the duration and magnitude of human and environmental
exposure to the chemical substances, as discussed in the January 21,
2015, proposed SNUR (Ref. 1). The category of articles subject to the
SNUR has not been modified since the 2015 proposed rule; therefore, EPA
does not need to modify any of its considerations in order to make the
finding under section 5(a)(5). Based on the information provided in the
2015 proposed SNUR, EPA affirmatively finds under TSCA section 5(a)(5)
that notification for import is justified by the reasonable potential
for exposure to perfluoroalkyl sulfonate chemicals as part of carpets.
Based on these
[[Page 45116]]
considerations, EPA has determined that: Importing perfluoroalkyl
sulfonate chemicals identified in 40 CFR 721.9582 as part of carpets,
which were not ongoing as of January 21, 2015, the date on which the
proposed rule was published (Ref. 1), constitutes a significant new use
and warrants making the exemption at 40 CFR 721.45(f) inapplicable to
importers of carpets.
V. Applicability of the General Provisions
The general provisions for SNURs appear under 40 CFR part 721,
subpart A, and they apply to this rule except as modified by the rule.
These provisions describe persons subject to the rule, recordkeeping
requirements, exemptions to reporting requirements, and applicability
of the rule to uses occurring before the effective date of the final
rule. However, EPA is making the exemption at 40 CFR 721.45(f)
inapplicable to persons who import LCPFAC chemicals substances listed
in the list of LCPFAC chemical substances in Unit II. and PFOA or its
salts as part of a surface coating of an article (See Unit I. for
examples of PFOA salts). Additionally, EPA is making the exemption at
40 CFR 721.45(f) inapplicable to persons who import perfluoroalkyl
sulfonate chemicals substances listed in 40 CFR 721.9582 as part of
carpets. As a result, persons subject to the provisions of this final
rule would not be exempt from submitting a significant new use notice
if they import those LCPFAC chemical substances, including PFOA or its
salts, as part of a surface coating of an article or if they import
perfluoroalkyl sulfonate chemical substances as part of carpets.
However, EPA is retaining the exemption at 40 CFR 721.45(f) for persons
who process chemical substances as part of an article because existing
stocks of articles may still contain LCPFAC or perfluoroalkyl sulfonate
chemical substances. Provisions relating to user fees appear at 40 CFR
part 700. Additionally, TSCA, as amended by the Lautenberg Act, makes
the provision at 40 CFR 721.45(h) inapplicable.
According to 40 CFR 721.1(c), persons subject to SNURs must comply
with the same notice requirements and EPA regulatory procedures as
described in 40 CFR part 720 for submitters of Premanufacture Notices
(PMNs) under TSCA section 5(a)(1)(A), at least to the extent there is
no conflict with the provisions at part 721. In addition, the
information submission requirements of TSCA sections 5(b) and 5(d)(1)
and the exemptions authorized by TSCA sections 5(h)(1), (h)(2), (h)(3),
and (h)(5) apply to SNURs.
Once EPA receives a SNUN, EPA must either determine that the
significant new use is not likely to present an unreasonable risk of
injury or take such other regulatory action as is required by TSCA
section 5(a)(3) before the manufacturing (including importing) or
processing for the significant new use can commence. If EPA determines
that the significant new use is not likely to present an unreasonable
risk, EPA is required under TSCA section 5(g) to make public, and
submit for publication in the Federal Register, a statement of EPA's
finding.
Persons who export or intend to export a chemical substance
identified in the proposed or final SNUR are subject to the export
notification provisions of TSCA section 12(b). The regulations that
interpret TSCA section 12(b) appear at 40 CFR part 707, subpart D. In
accordance with 40 CFR 707.60(b), this final SNUR does not trigger
notice of export for articles. Persons who import a chemical substance
identified in a final SNUR are subject to the TSCA section 13 import
certification requirements, codified at 19 CFR 12.118 through 12.127;
see also 19 CFR 127.28. Such persons must certify that the shipment of
the chemical substance complies with all applicable rules and orders
under TSCA, including any SNUR requirements. The TSCA section 13 import
certification requirement applies to articles containing a chemical
substance or mixture if so required by the Administrator by a specific
rule under TSCA. At this time, EPA is not requiring import
certification for these chemical substances as part of articles. The
EPA policy on import certification appears at 40 CFR part 707, subpart
B.
VI. Applicability of Rule to Uses Occurring Before Effective Date of
the Final Rule
As discussed in the Federal Register of April 24, 1990 (55 FR
17376) (FRL-3658-5) (Ref. 30), EPA has decided that the intent of TSCA
section 5(a)(1)(B) best served by designating a use as a significant
new use as of the date of publication of the proposed rule (including
the posting of a pre-publication copy of the rule) rather than as of
the effective date of the final rule. If uses begun after publication
of the proposed rule were considered ongoing rather than new, it would
be difficult for EPA to establish significant new uses, because a
person could defeat the SNUR by initiating the proposed significant new
use before the rule became final, and then argue that the use was
ongoing as of the effective date of the final rule. Thus, persons who
began commercial manufacture or processing of LCPFAC and perfluoroalkyl
sulfonate chemical substances after the proposal was published on
January 21, 2015, must cease such activity before the effective date of
this final rule. These persons would have to comply with all applicable
SNUR notice requirements and wait to resume the commercial manufacture
or processing of the subject chemical substances until EPA has made a
determination. Uses arising after the publication of the proposed rule
are distinguished from uses that exist at publication of the proposed
rule. The former would be new uses, the latter would be ongoing uses,
except that uses that are ongoing as of the publication of the proposed
rule would not be considered ongoing uses if they have ceased by the
date of issuance of a final rule. Public commenters on the proposed
rule and the supplement to the proposal identified ongoing uses, which
have been captured in the Response to Comments in Unit XII. (Ref. 3)
and are not covered by this SNUR. Ongoing uses cannot be subject to a
SNUR.
VII. Development and Submission of Information
EPA recognizes that TSCA section 5 does not usually require
developing new information (e.g., generating test data) before
submission of a SNUN; however, there is an exception: development of
information is required where the chemical substance subject to the
SNUR is also subject to a rule, order, or consent agreement under TSCA
section 4 (see TSCA section 5(b)(1)). Also pursuant to TSCA section
4(h), which pertains to reduction of testing of vertebrate animals, EPA
encourages consultation with the Agency on the use of alternative test
methods and strategies (also called New Approach Methodologies or
NAMs), if available, to generate any recommended test data. EPA
encourages dialogue with Agency representatives to help determine how
best the submitter can meet both the data needs and the objective of
TSCA section 4(h).
In the absence of a TSCA section 4 test rule covering the chemical
substance, persons are required to submit only information in their
possession or control and to describe any other information known to or
reasonably ascertainable by them (15 U.S.C. 2604(d); 40 CFR 721.25, and
40 CFR 720.50). However, as a general matter, EPA recommends that SNUN
submitters include information that would permit a reasoned evaluation
of risks posed by the chemical substance
[[Page 45117]]
during its manufacturing (including importing), processing, use,
distribution in commerce, or disposal. EPA encourages persons to
consult with the Agency before submitting a SNUN. As part of this
optional pre-notice consultation, EPA would discuss specific
information it believes may be useful in evaluating a significant new
use.
Submitting a SNUN that does not itself include information
sufficient to permit a reasoned evaluation may increase the likelihood
that EPA will either respond with a determination that the information
available to the Agency is insufficient to permit a reasoned evaluation
of the health and environmental effects of the significant new use or,
alternatively, that in the absence of sufficient information, the
manufacturing (including importing), processing, distribution in
commerce, use, or disposal of the chemical substance may present an
unreasonable risk of injury to health or the environment.
SNUN submitters should be aware that EPA will be better able to
evaluate SNUNs and define the terms of any potentially necessary
controls if the submitter provides detailed information on human
exposure and environmental releases that may result from the
significant new uses of the chemical substance.
VIII. SNUN Submissions
EPA recommends that submitters consult with the Agency prior to
submitting a SNUN to discuss what information may be useful in
evaluating a significant new use. Discussions with the Agency prior to
submission can afford ample time to conduct any tests that might be
helpful in evaluating risks posed by the chemical substance. According
to 40 CFR 721.1(c), persons submitting a SNUN must comply with the same
notice requirements and EPA regulatory procedures as persons submitting
a PMN, including submission of test data on health and environmental
effects as described in 40 CFR 720.50. SNUNs must be submitted on EPA
Form No. 7710-25, generated using e-PMN software, and submitted to the
Agency in accordance with the procedures set forth in 40 CFR 721.25 and
40 CFR 720.40. E-PMN software is available electronically at http://www.epa.gov/opptintr/newchems.
IX. Economic Analysis
A. SNUNs
EPA has evaluated the potential costs of establishing SNUR
reporting requirements for potential manufacturers and processors of
the chemical substance included in this final rule (Ref. 4). In the
event that a SNUN is submitted, average costs are estimated at
approximately $23,000 per SNUN submission for large business submitters
and about $10,000 for small business submitters. These estimates
include the cost to prepare and submit the SNUN (averaging about
$7,100), and the payment of a user fee. Businesses that submit a SNUN
would be subject to either a $16,000 user fee required by 40 CFR
700.45(c)(2)(ii), or, if they are a small business, a reduced user fee
of $2,800 (40 CFR 700.45(c)(1)(ii)). The costs of submission of SNUNs
will not be incurred by any company unless a company decides to pursue
a significant new use as defined in this final SNUR. EPA's complete
economic analysis is available in the public docket for this rule (Ref.
4).
B. Export Notification
Under TSCA section 12(b) and the implementing regulations at 40 CFR
part 707, subpart D, exporters must notify EPA if they export or intend
to export a chemical substance or mixture for which, among other
things, a rule has been proposed or promulgated under TSCA section 5.
For persons exporting a substance that is the subject of a SNUR, a one-
time notice to EPA must be provided each calendar year for the first
export or intended export to a particular country. The total costs of
export notification will vary by chemical, depending on the number of
required notifications (i.e., the number of countries to which the
chemical is exported).
C. Import of Chemical Substances as Part of an Article
In making inapplicable the exemption relating to persons who import
certain LCPFAC chemical substances as part of the surface coating of an
article, this action may affect firms that plan to import types of
articles that may contain the subject chemical substances in a surface
coating. This is because while some firms have an understanding of the
contents of the articles they import other firms do not. EPA
acknowledges that importers of articles may have varying levels of
knowledge about the chemical content of the articles that they import.
These parties may need to become familiar with the requirements of the
rule. And while not required by the SNUR, these parties may take
additional steps to determine whether the subject chemical substances
are part of the articles that they are considering for import. This
determination may involve activities such as gathering information from
suppliers along the supply chain, and/or testing samples of the article
itself. Costs vary across the activities chosen and the extent of
familiarity a firm has regarding the articles it imports. Cost ranges
are presented in Understanding the Costs Associated with Eliminating
Exemptions for Articles in SNURs (Ref. 31). Based on available
information, EPA believes that article importers that choose to
investigate their products will incur costs at the lower end of the
ranges presented in the Economic Analysis. For those companies choosing
to undertake actions to assess the composition of the articles they
import, EPA expects that importers will take actions that are
commensurate with the company's perceived likelihood that a chemical
substance might be a part of an article for the significant new uses
identified in Units II. and III., and the resources it has available.
Example activities and their costs are provided in the accompanying
Economic Analysis of this final rule (Ref. 4).
X. Alternatives
Before proposing this SNUR, EPA considered the following
alternative regulatory action: Promulgate a TSCA section 8(a) Reporting
Rule.
Under a TSCA section 8(a) rule, EPA could, among other things,
generally require persons to report information to the Agency when they
manufacture (including import) or process a chemical substance for a
specific use or any use. However, for LCPFAC and perfluoroalkyl
sulfonate chemical substances, the use of TSCA section 8(a) rather than
SNUR authority would have several limitations. First, if EPA were to
require reporting under TSCA section 8(a) instead of TSCA section 5(a),
that action would not ensure that EPA receives timely advance notice of
future manufacturing (including importing) or processing of LCPFAC
chemical substances (including as part of an article and components
thereof) for new uses that may produce changes in human and
environmental exposures. Nor would action under 8(a) ensure that an
appropriate determination (relevant to the risks of such manufacturing
(including importing) or processing) has been issued prior to the
commencement of such manufacturing (including importing) or processing.
Furthermore, a TSCA section 8(a) rule would not ensure that
manufacturing (including importing) or processing for the significant
new use cannot proceed until EPA has taken the required actions under
TSCA sections 5(e) or 5(f) in the event that EPA determines any of the
following: (1) That the significant new
[[Page 45118]]
use presents an unreasonable risk under the conditions of use (without
consideration of costs or other non-risk factors, and including an
unreasonable risk to a potentially exposed or susceptible subpopulation
identified as relevant by EPA); (2) that the information available to
EPA is insufficient to permit a reasoned evaluation of the health and
environmental effects of the significant new use; (3) that in the
absence of sufficient information, the manufacture (including import),
processing, distribution in commerce, use, or disposal of the
substance, or any combination of such activities, may present an
unreasonable risk (without consideration of costs or other non-risk
factors, and including an unreasonable risk to a potentially exposed or
susceptible subpopulation identified as relevant by EPA); or (4) that
there is substantial production and sufficient potential for
environmental release or human exposure (as defined in TSCA section
5(a)(3)(B)(ii)(II)).
In view of the health concerns about LCPFAC and perfluoroalkyl
sulfonate chemical substances if used for a significant new use, EPA
believes that a TSCA section 8(a) rule for this substance would not
meet EPA's regulatory objectives at this time.
XI. Scientific Standards, Evidence, and Available Information
EPA has used scientific information, technical procedures,
measures, methods, protocols, methodologies, and models consistent with
the best available science, as applicable. These information sources
supply information relevant to whether a particular use would be a
significant new use, based on relevant factors including those listed
under TSCA section 5(a)(2). Consistent with EPA's past practice for
issuing SNURs under TSCA section 5(a)(2), EPA's decision to promulgate
a SNUR for a particular chemical use need not be based on an extensive
evaluation of the hazard, exposure, or potential risk associated with
that use; as such, the January 2015 proposed rule (Ref. 1), the 2020
supplemental proposal (Ref. 2), and this final rule are not based on an
evaluation of expected risks.
The clarity and completeness of the data, assumptions, methods,
quality assurance, and analyses employed in EPA's decision are
documented, as applicable and to the extent necessary for purposes of
the January 2015 proposed rule, the 2020 supplemental proposal, and
this final rule, in Unit III. and in the references cited throughout
the three preambles. Considering the extent to which the various
information, procedures, measures, methods, protocols, methodologies or
models used in EPA's decision have been subject to independent
verification or peer review, EPA believes that their use is appropriate
in this rule. EPA recognizes, based on the available information, that
there is variability and uncertainty in whether any particular
significant new use would actually present an unreasonable risk. For
precisely this reason, EPA is proposing to require notice and review
for these uses at such time as they are known more definitively.
XII. Response to Public Comment
The Agency reviewed and considered all comments received related to
the 2015 proposed rule (Ref. 1) and the 2020 supplement to the proposed
rule (Ref. 2). Copies of all comments are available in the docket for
this action (EPA-HQ-OPPT-2013-0225). Responses to all comments received
are in the document titled: ``Response to Comments on the Proposed
Long-Chain Perfluoroalkyl Carboxylate and Perfluoroalkyl Sulfonate
Chemical Substances Significant New Use Rule (SNUR)'' (Ref. 3), which
is also available in the docket. Six primary comments, covering the
majority of the issues raised by the comments received, are included
below.
1. Comment: Several commenters claimed ongoing uses of LCPFAC,
PFOA, or perfluoroalkyl sulfonate chemical substances and requested
that EPA modify the proposed SNUR to specifically recognize and exclude
from the definition of 'significant new uses' certain ongoing
activities that do not appear to have been previously identified by the
Agency to be ongoing. Some commenters reiterated ongoing uses that EPA
had already identified as ongoing. One commenter suggested that EPA
should define ongoing uses ``in a manner that is not company
specific.'' Several commenters requested that EPA designate ``use in
semiconductor processing, manufacturing or semiconductor component
assembly'' as not a significant new use for LCPFAC chemical substances
and maintain the exemption under 40 CFR 721.45(f) for all on-going uses
in the semiconductor industry. Two commenters asked EPA to exempt
medical supplies or other equipment that may be used during the COVID-
19 public health emergency. See the Response to Comment document (Ref.
3) for the specific Docket IDs for these comments.
Response: EPA reviewed all ongoing use claims, requested additional
information from commenters to clarify the claims, and has recognized
and excluded from the definition of 'significant new uses' certain
ongoing activities for certain chemicals. Exclusions from the
definition of 'significant new uses' are included with the regulation
amendment at 40 CFR 721.10536(b)(5).
While reviewing ongoing use claims, EPA found chemical substances
that did not fall within the scope of the SNUR. Additionally, during
communication with commenters that supplied ongoing use claims, EPA
discovered that in some instances commenters had ceased the use of
their reported chemical substance. Accordingly, EPA has not recognized
and excluded from the definition of 'significant new uses' ongoing use
claims that fall outside the scope of the SNUR, have ceased by the date
of issuance of the final rule, or were unable to be substantiated.
During the comment response process, EPA reached out to one
commenter who was unable to supply substantiation of their claim, yet
stated that their ongoing use claim was captured in communication from
the supplier directly with EPA. As such, their ongoing use claim was
reviewed and has been addressed in the comment submitted by commenter's
supplier.
With regards to the use of LCPFAC chemical substances by the
semiconductor industry, it has not been EPA's practice to identify an
industry as a whole when recognizing ongoing uses. Commenters stated
that LCPFAC chemical substances used in the semiconductor industry may
be present in surfactants, coatings, seals, gaskets, hoses, motors,
electrical wiring, tools, robots, parts, ancillary equipment, and other
components but were unable to provide specific information such as a
Safety Data Sheet or other documentation to support their claim. EPA
was only able to verify ongoing uses within the semiconductor industry
in a subset of the claims made, which have been recognized in 40 CFR
721.10536.
During public comment for the supplemental rule (Ref. 2), EPA
received two comments stating ongoing uses of LCPFAC chemical
substances used in medical supplies, medical equipment, and for
pharmaceutical or biopharmaceutical research applications that may be
important to the COVID-19 pandemic response. EPA agrees that ongoing
uses, especially ones critical to COVID-19 pandemic response, should
not be restricted by this SNUR. TSCA section 3(2)(B) excludes devices
regulated under the Federal Food, Drug, and Cosmetic Act from the
definition of a chemical substance under TSCA. Gloves (21 CFR
880.6250), gowns (21 CFR 880.6265), and masks are all listed
[[Page 45119]]
separately as devices in FDA's regulations and such devices would not
be covered by this SNUR. However, it is important to note that other
face masks, gloves, and personal protective equipment that are marketed
to the general public for general, non-medical purposes, would be
covered by the SNUR if the use is not ongoing. As with other verified
ongoing uses, EPA has also exempted the ongoing uses of certain LCPFAC
chemical substances used in pharmaceutical and biopharmaceutical
research from this rule. EPA, however, has not broadly exempted all
uses of LCPFAC chemical substances used in pharmaceutical and
biopharmaceutical research because only a select number of applications
are ongoing.
When possible, EPA has made explicit chemical and use specific
exclusions from the definition of `significant new uses' rather than
broad industry or categorical exclusions. As reflected by the
exclusions in the final rule, ongoing activities include manufacturing
(including import) or processing of these chemical substances. EPA will
continue to work with industry to phase out LCPFAC, PFOA and its salts,
and perfluoroalkyl sulfonate chemical substances and will review the
need to promulgate future rules as necessary. As a result of public
comments received, EPA recognizes manufacture, import, or processing of
certain LCPFAC chemical substances for the following uses as ongoing:
Use of LCPFAC chemical substances for use in an
antireflective coating, photoresists, or surfactant for use in
photomicrolithography and other process to produce semiconductors or

2. Comment: Several commenters believe that the lack of LCPFAC CAS
numbers and the generic identification of PFOA and its salts provide
insufficient information for entities to understand what chemicals the
rule encompasses. They believe that EPA must define the universe of
covered chemicals that would be subject to the regulation. See the
Response to Comment document (Ref. 3) for the specific Docket IDs for
these comments.
Response: TSCA section 26(c) expressly recognizes that an
action may be taken with respect to a category of chemical substances
or mixtures based on chemical structure, and EPA believes the most
precise way to identify the chemicals subject to this SNUR is through
the chemical structure definition. Downstream customers should have
sufficient information from suppliers (i.e., CAS registry number and
unique chemical identity) to generate the specific structure for any
potentially reportable substance and compare to the LCPFAC category
definition.
As a convenience to the regulated community, EPA has made available
in the public docket an illustrative list of
[[Page 45120]]
chemical substances subject to the rule (Ref. 32). As part of that
list, EPA has provided specific examples of chemicals that meet the
various components of the LCPFAC category definition. The list is not
exhaustive, but rather provides a guide to help readers determine
whether this rule applies to them.
Additionally, Congress added certain active LCPFAC chemical
substances to the Toxics Release Inventory (TRI) list. These chemicals
were added to the TRI list under section 7321(b)(1) of the National
Defense Authorization Act of fiscal year 2020. TRI added both LCPFAC
and perfluoroalkyl sulfonate chemical substances that were identified
as active in commerce on the TSCA inventory that was published in
February 2019. While this list includes only LCPFAC chemicals on the
active inventory, it may assist the regulated community in determining
whether or not a given chemical substance is subject to this rule. The
list can be found on EPA's website and a citation is included in Unit
XIII. (Ref. 33).
3. Comment: Several commenters provided comment on whether EPA
could adopt a de minimis threshold for determining ``reasonable
potential for exposure'' and if so, how that de minimis threshold could
be established. Some comments supported the establishment of a
threshold while others opposed the idea of a de minimis threshold. One
commenter recommended a standard default de minimis threshold of 0.1%
for articles for all SNURs. One commenter did not have an opinion on
the establishment of a threshold or as a de minimis exemption but did
state that they were ``interested in EPA establishing a
characterization of the `reasonable potential for exposure' what might
be `reasonably ascertainable' with specific criteria for determining
this.'' See the Response to Comment document (Ref. 3) for the specific
Docket IDs for these comments.
Response: EPA appreciates the comments received. EPA is not
establishing a de minimis threshold for determining ``reasonable
potential for exposure'' in this final rule. EPA will, however,
continue to engage with interested stakeholders on this issue and
continue to consider whether guidance for applying this standard may be
appropriate in the future, whether as a general matter or, for
instance, as applied to specific categories of substances or potential
exposures.
As a general proposition, EPA believes that TSCA section 5(a)(5)
actions should be considered on a case-by-case basis. Each time EPA
considers requiring notification under TSCA section 5(a)(5), EPA will
have to consider whether the ``reasonable potential for exposure'' to
the chemical substance through the article or category of articles
justifies notification. Since the use designated as a significant new
use does not currently exist, EPA is deferring a detailed consideration
of potential exposures related to that use until there is a specific
condition of use and data to review. If EPA receives a SNUN, EPA would
evaluate the potential releases from the article and with information
specific to that article.
TSCA section 5(a)(5) does not establish an explicit threshold that
an exposure must meet in order to be considered a ``reasonable
potential for exposure'' or to ``justify notification.'' Rather, TSCA
section 5(a)(5) states: ``The Administrator may require notification
under this section for the import or processing of a chemical substance
as part of an article or category of articles under paragraph
(1)(A)(ii) if the Administrator makes an affirmative finding in a rule
under paragraph (2) that the reasonable potential for exposure to the
chemical substance through the article or category of articles subject
to the rule justifies notification.'' If there is evidence that a
chemical substance is or may be released from an article such that
there is a reasonable potential of exposure to the chemical substance,
EPA thinks the Agency can reasonably find the statutory criterion to be
met in most or all cases.
For this final rule, EPA believes that the reasonable potential for
exposure was adequately demonstrated by the studies cited in both the
2015 proposed rule (Ref. 1) and the 2020 supplement to the proposed
rule (Ref. 2). The studies cited during the rulemaking process
represent the exposures that could result from the significant new uses
subject to the SNUR. In showing that releases have been documented from
articles using LCFAC chemical substances as a surface coating (Refs.
21, 22, 23, 24, and 25), EPA asserts that the statutory standard has
been met to show that there is reasonable potential for exposure from
these significant new uses. EPA also concludes, on the record before
it, that this reasonable potential for exposure justifies notification.
4. Comment: Several commenters provided comment on whether or not
the Agency should include a safe harbor provision for importers of
articles that can demonstrate their use was ongoing prior to the
effective date of this rule. Some comments supported the establishment
of a safe harbor provision while others opposed the idea of a safe
harbor provision. One commenter recommended that EPA ``establish a
rebuttable presumption that a SNUN is not required for an imported
article if the foreign supplier of that article certifies in writing
that the article (including all components of the article) was not
manufactured using any of the substances identified in the Supplemental
Proposal.'' Another commenter asked that EPA allow importers to rely on
supplier/manufacture certifications for purposes of compliance. Related
to the idea of a safe harbor provision, several commenters emphasized
complex supply chains that comprise many industries and the
difficulties this would pose when determining if an article contains a
subject chemical substance. See the Response to Comment document (Ref.
3) for the specific Docket IDs for these comments.
Response: EPA appreciates the comments received. EPA is not
establishing a safe harbor provision in this final rule. EPA makes
every effort to notify manufacturers and processors of chemical
substances that may be subject to a given rule, so that they may
participate in the regulatory process. EPA provided notice to importers
in the 2015 proposed rule and again provided notice of the proposed
requirements in the 2020 supplemental proposal. A safe harbor approach
undermines the regulatory process for what uses are allowed by
permitting a manufacturer to claim a use was ongoing at the time the
SNUR was issued. For this final rule, EPA does not believe there should
be a safe-harbor provision for uses not identified as ongoing uses in
the SNUR, particularly since notice of the requirements of this action
were provided five years ago. As part of the public comment period for
the proposed rule and supplemental to the proposed rule, EPA received
comments of ongoing uses of LCPFAC chemical substances as part of a
surface coating on articles and has recognized those uses as ongoing
because ongoing uses are not subject to SNURs. Similarly, a general
safe-harbor provision may provide incentives for importers to not
submit comments to EPA during the public comment period regarding
ongoing uses not recognized in a proposed rule, because an importer who
fails to submit such comments, and thus to acknowledge such uses, would
be more easily able to claim that it did not realize the subject
chemical substance was in its product. An importer could potentially
use a safe harbor provision to justify a lack of involvement in a rule
making because the importer would have the opportunity to identify
chemicals later.
[[Page 45121]]
The importer could avoid participation early on because he could wait
to see if anyone else submitted comments and even if there are no
comments on his chemical use, he has the alternative to use the safe
harbor to challenge the rule.
While EPA acknowledges that imported articles may have a complex
supply chain, the most effective method to ensure that certain LCPFAC
chemical substances in this SNUR are not present in the surface coating
of imported articles is to encourage importers to know with specificity
the contents of what they are importing and to work with their foreign
manufacturers to ensure that an article does not contain certain LCPFAC
chemical substances in surface coatings.
Even though 19 CFR 12.119 allows EPA to establish TSCA section 13
import certification requirements for chemicals in articles, EPA did
not propose to require TSCA section 13 import certification for the
subject chemical substances when part of articles. Considering the use
of these chemicals in articles covered by this SNUR are no longer
ongoing, requiring TSCA section 13 import certification seems an
unnecessary requirement to include in the SNUR. This is consistent with
EPA's past practice of making the exemption at 40 CFR 721.45(f)
inapplicable without also requiring import certification or export
notification for these chemical substances as part of articles (40 CFR
721.2800; 40 CFR 721.10068). With or without an import certification
requirement, it is the importer that is ``responsible for [e]nsuring
that chemical importation complies with TSCA just as domestic
manufacturers are responsible for [e]nsuring that chemical manufacture
complies with TSCA.'' 40 CFR 707.20(b)(1).
EPA is not establishing a rebuttable presumption for this rule as
one commenter suggested. EPA, however, may consider the factors
discussed in EPA's import policy that may obviate or mitigate penalties
for violations with the import of articles, as described at 40 CFR
707.20(c)(1)(iii). The language at 40 CR 707.20(c)(1)(iii) states that
``[ . . . ] EPA realizes that sometimes importers may not have actual
knowledge of the chemical composition of imported mixtures. In these
cases, the importer should attempt to discover the chemical
constituents of the shipment by contacting another party to the
transaction (e.g., his principal or the foreign manufacturer). This
person may be able to identify the components of the mixture, or at
least state that the substances comply with TSCA. The greater the
effort an importer makes to learn the identities of the imported
substances and their compliance with TSCA, the smaller his chance of
committing a violation by importing a noncomplying shipment. If a
shipment is ultimately determined to have violated TSCA, the good faith
efforts of the importer to verify compliance, as evidenced by documents
contained in his files, may obviate or mitigate the assessment of a
civil penalty under section 16 of TSCA.''
EPA recognizes the complexities of imports. EPA will take into
consideration compliance certification and other documents
demonstrating that the importer relied on the supplier. EPA will also
continue to engage with interested stakeholders on how to ensure
compliance with this and future rules. Additionally, EPA maintains the
TSCA Hotline and responds to questions from industry. responds to
industry questions.
5. Comment: Several commenters raised concern over the issue of
impurities, stating that the impurity levels of PFOA and its salts
cannot be completely eliminated. Additionally, commenters reported that
fluorinated substances that do not fall into the scope of the SNUR may
degrade into in-scope LCPFAC substances. One commenter stated that
their imported article contained residual LCPFAC from the use of
polytetrafluoroethylene (PTFE) production, outside the US; the
commenter further indicated that their PTFE supplier is currently
working to develop an LCPFAC-free product, but at this time the use is
ongoing. Also, a comment stated that it is not possible for end users
to determine the presence of a given chemical substance, making it
difficult for determining ``intended use'' vs. ``impurity''.
As a result of the impurity concerns, multiple commenters requested
that EPA require suppliers to provide Certificate of Compliance to
importers. One comment suggested that the SNUR include all
fluoropolymer resins ``made with'' LCPFACs and exempt such products
``made without'' LCPFACs, even if such products may nevertheless bear
trace amounts of LCPFACs due to cross-contamination, to encourage
importers to demonstrate compliance by obtaining Certificates of
Compliance from their overseas suppliers. See the Response to Comment
document (Ref. 3) for the specific Docket IDs for these comments.
Response: To the extent the chemical substance subject to the SNUR
is only ``unintentionally present'' at the point of foreign
manufacture, it is already exempt from reporting by the importer as an
imported impurity. See 40 CFR 721.45(d). As such, importers are not
required to submit a SNUN for or report on a substance based simply on
that substance's presence as an impurity (i.e., a chemical substance is
unintentionally present with another chemical substance, 40 CFR
720.3(m)). Additionally, the impurity exemption at 40 CFR 721.45(d)
includes domestic manufacture and processing.
EPA is aware of the issues related to perfluorinated chemical
impurities and polymer degradation. Given that the Agency did not
propose to require a certification procedure, it does not agree that a
certification procedure should be specified and incorporated into the
final rule. However, the Agency continues to study this issue and has
not ruled out a later proposal to require import certification for
these chemical substances as part of articles.
With or without an import certification requirement, it is the
importer that is ``responsible for [e]nsuring that chemical importation
complies with TSCA just as domestic manufacturers are responsible for
[e]nsuring that chemical manufacture complies with TSCA.'' 40 CFR
707.20(b)(1).
With regards to providing an additional exemption to importers on
the basis of being unable to determine the presence of a given chemical
substance, or an inability to determine whether a use is ``intended ''
vs. an ``impurity'', any exemption would create a safe-harbor for
importers based on lack of knowledge, thus creating incentives for
foreign suppliers to deliberately withhold information from importers.
This could greatly reduce the efficacy of this SNUR.
6. Comment: Several commenters requested that EPA consider
promulgating TSCA section 6(a) rules to directly restrict
perfluoroalkyl and polyfluoroalkyl substances (PFAS) and complete
planned development of a detailed assessment to determine if PFAS
chemical substances presents an unreasonable risk. See the Response to
Comment document (Ref. 3) for the specific Docket IDs for these
comments.
Response: TSCA section 6(a) states that ``[i]f the Administrator
determines in accordance with subsection (b)(4)(A) that the
manufacture, processing, distribution in commerce, use, or disposal of
a chemical or mixture, or that any combination of such activities,
presents an unreasonable risk of injury to health or the environment''
the Administrator shall take action under TSCA section 6(a). While EPA
appreciates the commenters request to promulgate a rule in accordance
with this provision, EPA is not doing so at
[[Page 45122]]
this time. Rather, at this time EPA believes that a rule under TSCA
section 5(a)(2), in conjunction with the 2010/2015 PFOA Stewardship
Program, is an effective method to protect human health and the
environment from any risks posed by LCPFAC and perfluoroalkyl sulfonate
chemical substances.
Through the 2010/2015 PFOA Stewardship Program, a voluntary risk
reduction program, eight major fluoropolymer and telomer manufacturers
and processors committed to voluntarily work toward a phase-out of
LCPFAC chemical substances (Ref. 34). As such, the reduced supply of
long-chain perfluorinated chemicals has led industries to more quickly
transition to alternative chemical substances, as noted in both public
comments and industry communication. For persons subject to this SNUR,
they are required to notify EPA at least 90 days prior to commencing
manufacture or processing of these chemical substances. This required
notification provides EPA with the opportunity to evaluate any
significant new use of the regulated perfluorinated chemical substances
and, if necessary, protect against potential unreasonable risks. EPA
continues to review the manufacturing, import, and processing of the
ongoing uses of these substances of concern. If EPA has reason to
believe that either a use of these chemical substances is no longer
ongoing or that a TSCA section 6(a) rule would better regulate LCPFAC
and perfluoroalkyl sulfonate chemical substances, EPA will consider
taking further regulatory action.

XIV. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.
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 for this action as required by
section 6(a)(3)(E) of Executive Order 12866.
EPA prepared an economic analysis of the potential costs and
benefits associated with this action. A copy of the economic analysis,
entitled ``Economic Analysis of the Significant New Use Rule for
Perfluoroalkyl Sulfonates and Long-Chain Perfluoroalkyl Carboxylate
Chemical Substances'' (Ref. 4), is available in the docket and is
briefly summarized in Unit XI.
B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs
This is a regulatory action subject to Executive Order 13771 (82 FR
9339, February 3, 2017). Details on the estimated costs and benefits of
this final rule can be found in EPA's analysis (Ref. 4), which is
available in the docket and is summarized in Unit I.E.
C. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA, 44 U.S.C. 3501 et seq. Burden is defined in 5 CFR
1320.3(b). The information collection activities associated with
existing chemical SNURs are already approved under OMB control number
2070-0038 (EPA ICR No. 1188); and the information collection activities
associated with export notifications are already approved under OMB
control number 2070-0030 (EPA ICR No. 0795). If an entity were to
submit a SNUN to the Agency, the annual burden is estimated to be less
than 100 hours per response, and the estimated burden for export
notifications is less than 1.5 hours per notification. In both cases,
burden is estimated to be lower for submitters who have already
registered to use the electronic submission system.
An agency may not conduct or sponsor, and a person is not required
to respond to a collection of information that requires OMB approval
under the PRA, unless it has been approved by OMB and displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations in Title 40 of the CFR, after appearing in the Federal
Register, are listed in 40 CFR, part 9, and included on the related
collection instrument, or form, as applicable.
D. Regulatory Flexibility Act (RFA)
Pursuant to section 605(b) of the RFA, 5 U.S.C. 601 et seq., I
certify that promulgation of this SNUR would not have a significant
economic impact on a substantial number of small entities. The
rationale supporting this conclusion is as follows.
A SNUR applies to any person (including small or large entities)
who intends to engage in any activity described in the rule as a
``significant new use.'' By definition of the word ``new'' and based on
all information currently available to EPA, it appears that no small or
large entities presently engage in such activities. Since this SNUR
will require a person who intends to engage in such activity in the
future to first notify EPA by submitting a SNUN, no economic impact
will occur unless someone files a SNUN to pursue a significant new use
in the future or forgoes profits by avoiding or delaying the
significant new use. Although some small entities may decide to conduct
such activities in the future, EPA cannot presently determine how many,
if any, there may be. However, EPA's experience to date is that, in
response to the promulgation of SNURs covering over 1,000 chemical
substances, the Agency receives only a handful of notices per year.
During the six-year period from 2005-2010, only three submitters self-
identified as small in their SNUN submission (Ref. 4). Based on this,
EPA believes that few SNUN submissions will occur as a result of the
rule. EPA believes the total cost of submitting a SNUN, $10,000 for
small business submitters, is relatively small compared to annual
revenues of the companies and does not have a significant economic
impact as compared to the cost of developing and marketing a chemical
new to a firm or marketing a new use of the chemical. This estimate
does not include any costs associated with importer's identification of
chemicals associated with the SNUR. While EPA does not have estimates
on the cost of developing and marketing a new chemical, it has
identified a mean reformulation cost of $31,700 and a maximum of
$114,000, which is well above the $10,000 SNUN costs.
Therefore, EPA believes that the potential economic impact of
complying with this final SNUR is not expected to be significant or
adversely impact a substantial number of small entities.
E. Unfunded Mandates Reform Act (UMRA)
Based on EPA's experience with proposing and finalizing SNURs,
State, local, and Tribal governments have not been impacted by these
rulemakings, and EPA does not have any reason to believe that any
State, local, or Tribal government would be impacted by this
rulemaking. As such, the requirements of sections 202, 203, 204, or 205
of UMRA, 2 U.S.C. 1531-1538, do not apply to this action.
F. Executive Order 13132: Federalism
This action will not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999), because it will
not have substantial direct effect on 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.
G. 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), because it will
not have any effect on tribal governments, on the relationship between
the Federal Government and the Indian tribes, or on the distribution of
power and responsibilities between the Federal Government and Indian
tribes.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997), because this action does not address environmental
health or safety risks, and EPA interprets Executive Order 13045 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.
[[Page 45124]]
I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This final rule is not subject to Executive Order 13211 (66 FR
28355, May 22, 2001), because this action is not expected to affect
energy supply, distribution, or use.
J. National Technology Transfer and Advancement Act (NTTAA)
Since this action does not involve any technical standards, section
12(d) of NTTAA, 15 U.S.C. 272 note, does not apply to this action.
K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
This final rule does not invoke special consideration of
environmental justice related issues as delineated by Executive Order
12898 (59 FR 7629, February 16, 1994), because EPA has determined that
this action will not have disproportionately high and adverse human
health or environmental effects on minority or low-income populations.
L. Congressional Review Act (CRA)
This action is subject to the CRA, 5 U.S.C. 801-808, and EPA will
submit a rule report to each House of the Congress and to the
Comptroller General of the United States. This action is not a ``major
rule'' as defined by 5 U.S.C. 804(2).
