TSCA Section 8(a)(7) Reporting and Recordkeeping Requirements for
Perfluoroalkyl and Polyfluoroalkyl Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing
reporting and recordkeeping requirements for Per- and Polyfluoroalkyl
Substances (PFAS) under the Toxic Substances Control Act (TSCA). In
accordance with obligations under TSCA, as amended by the National
Defense Authorization Act for Fiscal Year 2020, EPA proposes to require
certain persons that manufacture (including import) or have
manufactured these chemical substances in any year since January 1,
2011, to electronically report information regarding PFAS uses,
production volumes, disposal, exposures, and hazards. EPA is requesting
public comment on all aspects of this proposed rule and has also
identified items of particular interest for public input. In addition
to fulfilling statutory obligations under TSCA, this document will
enable EPA to better characterize the sources and quantities of
manufactured PFAS in the United States.

DATES: Comments must be received on or before August 27, 2021. Under
the Paperwork Reduction Act, comments on the information collection
provisions are best assured of consideration if the Office of
Management and Budget (OMB) receives a copy of your comments on or
before July 28, 2021.

ADDRESSES: Submit your comments, identified by docket identification
(ID) number EPA-HQ-OPPT-2020-0549, using the Federal eRulemaking Portal
at http://www.regulations.gov. Follow the online instructions for
submitting comments. Do not submit electronically any information you

SUPPLEMENTARY INFORMATION:

I. Executive Summary

A. Does this action apply to me?

    You may be potentially affected by this action if you currently or
have previously manufactured (defined by statute at 15 U.S.C. 2602(9)
to include import) a chemical substance that is a PFAS between January
1, 2011 and the effective date of the final rule. Note that this rule
is limited to manufacturers

(including importers) of PFAS that are covered as a ``chemical
substance'' under TSCA section 3(2). This rule does not require
reporting on substances that are excluded from the definition of
``chemical substance'' in TSCA section 3(2)(B). Those exclusions
include, but are not limited to: Any pesticide (as defined by the
Federal Insecticide, Fungicide, and Rodenticide Act) when manufactured,
processed, or distributed in commerce for use as a pesticide; any food,
food additive, drug, cosmetic, or device, as defined by the Federal
Food, Drug, and Cosmetic Act, when manufactured, processed, or
distributed in commerce for use as a food, food additive, drug,
cosmetic or device; tobacco or any tobacco product; any source
material, special nuclear material, or byproduct material as such terms
are defined in the Atomic Energy Act of 1954; and, any article the sale
of which is subject to the tax imposed by Section 4181 of the Internal
Revenue Code of 1954. Substances which have been manufactured or
imported for intended use as any food, food additive, drug, cosmetic,
or device, regulated by the Food and Drug Administration, are not
chemical substances under TSCA.
    The manufacture of PFAS as a byproduct is not exempt for the
purpose of this proposed rule. Unlike TSCA section 8(a)(1), which
specifically provides an exemption for small manufacturers and
processors, TSCA section 8(a)(7) provides no such exemption. Therefore,
this proposed rule under TSCA section 8(a)(7) does not exempt small
manufacturers from reporting and recordkeeping requirements. See the
discussion under Unit II.D. for further discussion of the inclusion of
small manufacturers in this proposed rule. The Agency's previous
experience with TSCA section 8(a)(1) collections, as well as the
Agency's understanding of disposal and other waste management methods
involving PFAS, suggests that most respondents affected by this
collection activity may be from the following North American Industrial
Classification System (NAICS) code categories:
     NAICS 324--Petroleum and Coal Product Manufacturing;
     NAICS 325--Chemical Manufacturing;
     NAICS 326113--Unlaminated Plastics Film and Sheet (except
Packaging) Manufacturing;
     NAICS 327910--Abrasive Product Manufacturing;
     NAICS 333999--All Other Miscellaneous General Purpose
Machinery Manufacturing;
     NAICS 334511--Search, Detection, Navigation, Guidance,
Aeronautical, and Nautical System and Instrument Manufacturing;
     NAICS 336111--Automobile Manufacturing;
     NAICS 423510--Metal Service Centers and Other Metal
Merchant Wholesalers;
     NAICS 424690--Other Chemical and Allied Products Merchant
Wholesalers;
     NAICS 447190--Other Gasoline Stations;
     NAICS 551112--Offices of Other Holding Companies;
     NAICS 562--Waste Management and Remediation Services.
    Since other entities may also be affected, the Agency has not
attempted to describe all the specific entities and corresponding NAICS
codes for entities that may be interested in or affected by this
action, but rather has provided a guide to help readers determine
whether this document applies to them. If you have any questions
regarding the applicability of this action to a particular entity,
consult the technical contact person listed under FOR FURTHER
INFORMATION CONTACT.
    In addition, please note that any use of the term ``manufacture''
in this document will encompass ``import'' and the term
``manufacturer'' will encompass ``importer.''

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

    EPA is proposing this rule pursuant to its authority in TSCA
section 8(a)(7) (15 U.S.C. 2607(a)(7)). The National Defense
Authorization Act for Fiscal Year 2020 (Pub. L. 116-92, section 7351)
amended TSCA section 8(a) in December 2019, adding section 8(a)(7),
titled PFAS Data. TSCA section 8(a)(7) requires EPA to promulgate a
rule ``requiring each person who has manufactured a chemical substance
that is a [PFAS] in any year since January 1, 2011'' to report
information described in TSCA section 8(a)(2)(A) through (G). This
includes a broad range of information, such as information related to
chemical identity and structure, production, use, exposure, disposal,
and health and environmental effects.
    TSCA section 14 imposes requirements for the assertion,
substantiation, and review of information that is claimed as
confidential (also known as confidential business information (CBI)).

C. What action is the Agency taking?

    EPA is proposing reporting and recordkeeping requirements under
TSCA section 8(a)(7) for PFAS manufactured in any year since January 1,
2011. EPA is providing a comment period during which the public will
have the opportunity to comment on this proposed action and its
proposed requirements. Commenters are encouraged to provide comments
and feedback related to the proposed reporting and recordkeeping
requirements presented in this Notification of Proposed Rulemaking
(NPRM), including the scope of PFAS covered by the rule (see Unit V.
for more discussion on specific items for which the Agency is
requesting comments). EPA is providing a comment period of 60 days from
the publication date of this NPRM.

D. Why is the Agency taking this action?

    The Agency is proposing this action pursuant to TSCA section
8(a)(7) to obtain certain information known to or reasonably
ascertainable by manufacturers of PFAS. TSCA section 8(a)(7) requires
the Agency to publish a final rule not later than January 1, 2023.

E. What are the incremental economic impacts?

    EPA has prepared an economic analysis of the potential impacts
associated with this proposed rule (Ref. 13). The primary purpose of
this proposed rule is the collection of detailed data on PFAS, as
required under TSCA section (8)(a)(7). One potential benefit of this
action is the information collected may serve as a basis to better
understand potential routes of exposure to PFAS and potential human
health and environmental impacts of certain PFAS, among other research
needs listed in the Agency's PFAS Action Plan.
    The industry is expected to incur one-time burdens and costs
associated with rule familiarization, form completion, CBI claim
substantiation, recordkeeping, and electronic reporting activities.
Under the proposed rule, EPA estimates a total industry burden of
approximately 122,104 hours, with a cost of approximately $9.8 million.
The affected small businesses subject to the proposed rule are expected
to incur $1,788,506 in costs for this one-time reporting, with per-firm
costs estimated to range from $16,864 to $92,390. The Agency is
expected to incur a burden of approximately 7,361 hours and a cost of
$948,078. The total social burden and cost are therefore estimated to
be approximately 129,465 hours and $10.8 million, respectively (Ref.
13).

F. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or email (see the above

Addresses section for submitting comments either by mail or hand
delivery). Clearly mark the part or all of the information that you
claim to be CBI. For confidential information in a disk or CD-ROM that
you mail to EPA, mark the outside of the disk or CD-ROM as CBI and then
identify electronically within the disk or CD-ROM the specific
information that is claimed as CBI. In addition to one complete version
of the comment that includes information claimed as CBI, a copy of the
comment that does not contain the information claimed as CBI must be
submitted for inclusion in the public docket. Information so marked
will not be disclosed except in accordance with procedures set forth in
40 CFR part 2.
    2. Tips for preparing your comments. When preparing and submitting
your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.

II. Background

A. What is TSCA Section 8(a)?

    TSCA section 8(a)(1) authorizes EPA to promulgate rules which
require entities, that are not considered small manufacturers or
processors, who manufacture, process, or propose to manufacture or
process a chemical substance, to maintain such records and submit such
reports as the EPA Administrator may reasonably require. Similarly,
under those rules, entities who manufacture, process, or propose to
manufacture or process a mixture or a chemical substance in small
quantities (subject to limitations) must maintain records and submit
reports to the extent necessary for the effective enforcement of TSCA.
    Under TSCA section 8(a)(2), EPA may require recordkeeping and
reporting of the following information:
     The covered common or trade name, chemical identity and
molecular structure of each chemical substance or mixture;
     Categories or proposed categories of use for each
substance or mixture;
     Total amount of each substance or mixture manufactured or
processed, the amounts manufactured or processed for each category of
use, and reasonable estimates of the respective proposed amounts;
     Descriptions of byproducts resulting from the manufacture,
processing, use, or disposal of each substance or mixture;
     All existing information concerning the environmental and
health effects of each substance or mixture;
     The number of individuals exposed, and reasonable
estimates on the number of individuals who will be exposed, to each
substance or mixture in their places of work and the duration of their
exposure, and;
     The manner or method of disposal of each substance or
mixture, and any change in such manner or method.
    Under TSCA section 8(a)(7), EPA must promulgate a rule to require
each person who has manufactured PFAS in any year since 2011 to report
the data described in TSCA section 8(a)(2)(A) through (G) to EPA.

B. What are PFAS?

    PFAS are synthetic organic compounds that do not occur naturally in
the environment. PFAS contain an alkyl carbon on which the hydrogen
atoms have been partially or completely replaced by fluorine atoms. The
strong carbon-fluorine bonds of PFAS make some of them resistant to
degradation and thus highly persistent in the environment (Refs. 1 and
2). Some of these chemicals have been used for decades in a wide
variety of consumer and industrial products (Ref. 1). Some PFAS have
been detected in wildlife, including higher trophic organisms,
indicating that at least some PFAS have the ability to bioaccumulate
(Ref. 2). Some PFAS can accumulate in humans and remain in the human
body for long periods of time (e.g., months to years) (Refs. 1, 2, and
3). As noted in EPA's PFAS Action Plan (Ref. 1), 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. As a result, several PFAS have been detected in human blood serum
(Refs. 1, 2, 3, and 4).
    Under TSCA section 8(b), EPA maintains the TSCA Chemical Substance
Inventory (``Inventory''), which contains all existing chemical
substances manufactured, processed, or imported in the United States
that do not qualify for an exemption or exclusion under TSCA (Ref. 5).
EPA has identified 1,346 PFAS on the Inventory as of April 2021, 669 of
which are on the active Inventory (i.e., in U.S. commerce). The list of
active chemicals includes those known to be in commerce after June
2006.

C. What would be the reporting standard?

    EPA is proposing that manufacturers will report information to the
extent that the information is known to or reasonably ascertainable by
the manufacturer (see TSCA section 8(b)(2)). ``Known to or reasonably
ascertainable by'' would be defined to include ``all information in a
person's possession or control, plus all information that a reasonable
person similarly situated might be expected to possess, control, or
know.'' This reporting standard would require reporting entities to
evaluate their current level of knowledge of their manufactured
products (including imports), as well as evaluate whether there is
additional information that a reasonable person, similarly situated,
would be expected to know, possess, or control. This standard carries
with it an exercise of due diligence, and the information-gathering
activities that may be necessary for manufacturers to achieve this
reporting standard may vary from case-to-case.
    This standard would require that submitters conduct a reasonable
inquiry within the full scope of their organization (not just the
information known to managerial or supervisory employees). This
standard may also entail inquiries outside the organization to fill
gaps in the submitter's knowledge. Such activities may, though not
necessarily, include phone calls or email inquiries to upstream
suppliers or downstream users or employees or other agents of the
manufacturer, including persons involved in the research and
development, import or production, or marketing of the PFAS. Examples
of types of information that are considered to be in a manufacturer's
possession or control, or that a reasonable person similarly situated
might be expected to possess, control, or know include: Files
maintained by the manufacturer such as marketing studies, sales
reports, or customer surveys; information contained in standard
references showing use information or concentrations of chemical
substances in mixtures, such as a Safety Data Sheet or a supplier
notification; and information from the Chemical Abstracts Service (CAS)
or from Dun & Bradstreet (D-U-N-S). This information may also include
knowledge gained through discussions, conferences, and technical
publications. This definition is identical to the definition of the
same term at 40 CFR 704.3. In addition, this is the same reporting
standard employed in the TSCA section 8(a) Chemical Data Reporting
(CDR) rule (see 40 CFR 711.15). EPA has also provided CDR reporting
guidance materials on this reporting standard, including hypothetical
examples of applying the ``known to or reasonably ascertainable by''
reporting standard in the context of collecting processing and use data
for CDR (Ref. 6, pages 45-47). Therefore, EPA anticipates many
reporters under this proposed rule will be familiar with this reporting
standard, and resources

are available to support those reporters who may not be familiar with
the standard. EPA acknowledges that it is possible that an importer,
particularly an importer of articles containing PFAS, may not have
knowledge that they have imported PFAS and thus not report under this
rule, even after they have conducted their due diligence under this
reporting standard as described in this paragraph. Such an importer
should document its activities to support any claims it might need to
make related to due diligence.
    In the event that a manufacturer does not have actual data (e.g.,
measurements or monitoring data) to report to EPA, the manufacturer
would be required to make ``reasonable estimates'' of such information.
``Reasonable estimates'' may rely, for example, on approaches such as
mass balance calculations, emissions factors, or best engineering
judgment.

D. Why are small businesses not excluded from reporting similar to
Chemical Data Reporting (CDR) and other section 8(a) reporting?

    Unlike TSCA section 8(a)(1), which provides an express exemption
for small manufacturers and processors, TSCA section 8(a)(7)
specifically states that ``each person who has manufactured a chemical
substance that is a perfluoroalkyl or polyfluoroalkyl substance'' shall
be subject to the rule. Rather than amend TSCA section 8(a)(1),
Congress chose to add an entirely new, standalone subsection to TSCA
section 8(a). This indicates an intent for TSCA section 8(a)(7) to
constitute separate, freestanding rulemaking authority; therefore, it
is not constrained by requirements and provisions in TSCA section
8(a)(1).
    However, in carrying out TSCA section 8, EPA shall, to the extent
feasible: (A) Not require reporting which is unnecessary or
duplicative; (B) Minimize the cost of compliance with TSCA section 8
and the rules issued thereunder on small manufacturers and processors;
and (C) Apply any reporting obligations to those persons likely to have
information relevant to the effective implementation of this subchapter
(TSCA section 8(a)(5)).

E. How will EPA use the information?

    TSCA section 8(a)(7) is silent on how the information collected
under the TSCA section 8(a)(7) rule is to be used. However, collecting
information on PFAS identities, uses, production volumes by category of
use, byproducts, environmental and health effects, workers exposure,
and disposal supports the Agency's mission in the PFAS Action Plan to
identify and better understand these chemicals and to increase
scientific research on them.
    EPA intends to use information on these chemicals to support
assessments of new and existing chemicals under TSCA. For instance,
information collected under this proposed rule will help inform future
assessments of potential exposure to these PFAS. The Agency would also
benefit from receiving all existing information related to human health
and environmental effects of such substances, in order to fulfill
additional environmental protection mandates beyond the TSCA program.
For instance, information on PFAS use, exposure, and effects may be
used to inform regulatory activities under the Safe Drinking Water Act
(42 U.S.C. 300f et seq.), the Resource Conservation and Recovery Act
(42 U.S.C. 6901 et seq.), and the Comprehensive Environmental Response,
Compensation, and Liability Act (42 U.S.C. 9601 et seq.), while data on
PFAS manufacturing sites and disposal methods may support contaminants
characterizations conducted to support contaminated site work and solid
waste management programs.
    Additionally, TSCA section 9(e) requires the EPA Administrator to
make information related to exposure or releases available to other EPA
offices or federal agencies if such exposures may be prevented or
reduced under another law. EPA may share such information collected
under this proposed rule as appropriate.

III. Summary of Proposed Reporting and Recordkeeping Requirements

    EPA is proposing reporting and recordkeeping requirements for
manufacturers of PFAS pursuant to TSCA section 8(a)(7).

A. What chemical substances would be reportable under this rule?

    1. Reportable chemicals substances. Under TSCA section 8(a)(7), EPA
must collect information on chemical substances that are
``perfluoroalkyl or polyfluoroalkyl'' substances or PFAS. EPA has
determined that any PFAS that fall within the structural definition,
described below, are the PFAS referred to in TSCA section 8(a)(7). For
this proposed rule, EPA has identified at least 1,364 chemical
substances and mixtures that are PFAS and would potentially be subject
to reporting under the final rule, if they have been manufactured in
any year since January 1, 2011.
    For the purposes of this proposed action, the structural definition
of PFAS includes per- and polyfluorinated substances that structurally
contain the unit R-(CF2)-C(F)(R')R''. Both the CF2 and CF moieties are
saturated carbons and none of the R groups (R, R' or R'') can be
hydrogen. It should be noted that this structural definition of PFAS is
a working definition which has been used by EPA's Office of Pollution
Prevention and Toxics when identifying PFAS on the TSCA Inventory. This
definition may not be identical to other definitions of PFAS used
within EPA and/or other organizations. To assist potential reporters
with determining whether certain substances may be covered under this
structural definition, EPA has identified specific PFAS covered by this
proposed rule. These will be included as non-exhaustive examples in the
rule where it is possible to do so without divulging information
claimed as CBI. The scope of PFAS examples listed in this proposal
includes:
     All PFAS listed as active on the TSCA Inventory. This
includes PFAS that are identified by CAS number; confidential chemicals
whose generic names contain ``fluor'' and are identified by Accession
number; and confidential chemicals whose generic names do not contain
``fluor'', and therefore, are not listed by CASRNs, Accession numbers,
or low-volume exemptions (LVE) case numbers (see note on structural
diagram examples below).
     All PFAS that are subject to TSCA section 5 (new
chemicals) LVE applications per 40 CFR 723.50 that have been granted by
EPA. This includes the PFAS that were subject to granted LVE
applications that have since been withdrawn by the LVE application
submitter. Additional discussion on LVEs is below.
    Under TSCA section 5, any person who intends to manufacture a
chemical not on the TSCA Inventory must first notify EPA. Typically,
this is done by submission of a premanufacture notice (PMN) (Ref. 8).
However, for low-volume chemical substances (i.e., chemical substances
manufactured at no more than 10,000 kg per year) companies can submit a
LVE application to EPA per 40 CFR 723.50. EPA may either grant or deny
an LVE submission after review, but LVEs that are granted are not
listed on the Inventory, unlike PMN chemical substances. Therefore, EPA
is also providing a list of PFAS chemicals for which EPA granted an LVE
notice.
    LVE submitters may choose to withdraw their granted LVE
application. In order to compile a comprehensive dataset as authorized
under TSCA section 8(a)(7), EPA is including these

withdrawn LVE submissions in the list of examples subject to this
proposed rule if they were submitted since 2011.
     This proposed rule will also include structural diagrams
to capture any PFAS whose CAS or Accession numbers could not be
divulged due to CBI claims, whose identity is not listed on the TSCA
Inventory because it is subject to an LVE, or which is a byproduct not
listed on the Inventory and not subject to an LVE, yet meets the
structural definition. The list of identified PFAS and structural
diagrams can also be found in the docket (Ref. 7). The PFAS included in
the list and identified by the structural diagrams are examples of
substances that meet this rule's definition of PFAS; it is not a
comprehensive list of all substances within this rule's scope.
    EPA is providing these examples of PFAS for the purpose of
assisting manufacturers in determining whether a chemical substance
they have manufactured in any year since 2011 meets this proposed
rule's definition of PFAS. Because the Inventory's active designation
dates back to June 2006, it is possible for a firm to have manufactured
one of these listed PFAS yet not be required to report under this
proposed rule, if they have manufactured it only in the period prior to
January 1, 2011.
    This list was developed as of April 2021. EPA anticipates updating
this list prior to promulgating the final rule, both in response to
public comment, and as a result of PMNs added to the Inventory and LVEs
granted by EPA between April 2021 and the date of publication of the
final rule.
    For the purposes of this proposed rule, articles containing PFAS,
including imported articles containing PFAS (such as articles
containing PFAS as part of surface coatings), are included in the scope
of reportable chemical substances. TSCA does not define articles, nor
does the statute define articles as a category of substances exclusive
of chemical substances. EPA therefore considers its ability to regulate
chemical substances to encompass authority to regulate articles
containing such chemical substances. Additionally, the Agency would
benefit from collecting the requested information on PFAS-containing
articles (including articles containing PFAS as part of surface
coatings) because the information would improve the Agency's knowledge
of various products which may contain PFAS, their categories of use,
production volumes, and exposure data. Such data are not currently
known to EPA. However, EPA acknowledges that some article
manufacturers, including article importers, may not have such
information known to or reasonably ascertainable by them and may not
meet the reporting standard as described in Unit II.C. To this end,
information that helps EPA better understand data gaps is useful
information for EPA to have. Therefore, articles are within the scope
of reportable substances under this proposed rule, though EPA is
requesting comments on whether imported articles containing PFAS should
be within scope (see Unit IV.1).
    2. Proposed exceptions to reporting for duplicative reporting. TSCA
section 8(a)(5) requires EPA, to the extent feasible when carrying out
TSCA section 8, to avoid requiring unnecessary or duplicative
reporting. The Agency seeks to avoid collecting data on PFAS that would
duplicate information already reported to the Agency. While developing
this rule EPA reviewed the data elements submitted under the Chemical
Data Reporting Rule and determined that there may be some overlap with
the information requested under the proposed rule. EPA is proposing to
allow reporting entities to indicate in the reporting tool that they
have previously provided such information to EPA through CDR for
certain data elements. The Agency has identified the following data
elements which the reporter may be able to indicate has already been
submitted to EPA:
     Physical state of the chemical or mixture;
     Industrial processing and use type, sector(s), functional
category(ies), and percent of production volume for each use;
     Consumer and/or commercial indicator, product
category(ies), functional category(ies), percent of production volume
for each use, indicator for use in products intended for children, and
maximum concentration in the product, and;
     Number of workers reasonably likely to be exposed for each
combination of industrial processing or use operation, sector, and
function, and the number of commercial workers reasonably likely to be
exposed if the PFAS is contained in a commercial product.
    If a manufacturer covered under this proposed rule has previously
submitted required information to EPA for some years since 2011, but
not for all years, EPA is proposing that the manufacturer may indicate
in the reporting tool the year(s) for which the manufacturer has
already submitted that data to EPA as part of CDR. For instance, CDR
reporters are required to submit the total annual domestically
manufactured production volume and the total annual imported volume
separately, only for the principal reporting year (e.g., 2019 for the
2020 reporting cycle), but reporting only the combined total annual
production volume is required for the intervening years. In this case,
a reporter under this proposed rule would be able to indicate that the
two different production volumes have been previously submitted to EPA
for the CDR reporting year(s), but would still need to report for the
intervening year(s) not previously submitted under CDR. Additionally,
there are some data elements for which CDR reporters may have
previously reported information to EPA, although these data elements
were only added to the CDR reporting requirements in 2020. Therefore,
some manufacturers under this proposed rule may have submitted the
following information to CDR for some years covered by this proposed
rule, but not all, and would still be required to report this
information for the missing year(s):
     Domestically manufactured production volume;
     Imported production volume;
     Volume directly exported; and
     Indicator for imported but never physically at site.
    EPA welcomes public comment on concerns related to duplicative
reporting (see Unit V.).

B. When would reporting be required?

    EPA proposes that persons who have manufactured a PFAS at any time
since January 1, 2011, would report to EPA during a six-month
submission period, which would begin six months following the effective
date of the final rule. Therefore, manufacturers would ultimately have
one year following the effective date of the final rule to collect and
submit all required information to EPA. EPA believes by providing six
months between the effective date of the rule and the start of the
submission period, this would allow sufficient time for both the Agency
to finalize the reporting tool and for reporters to familiarize
themselves with the rule and compile the required information. Since
this section 8(a)(7) reporting rule will be collecting similar
information as CDR, EPA anticipates many reporters will be familiar
with the types of information requested and how to report. The CDR
submission period is four months, every four years. Since this proposed
rule spans a longer time than the four-year CDR reporting cycle, EPA
acknowledges additional time may be needed in the PFAS submission
period. EPA believes that six months is adequate time for submissions,
in addition to the six-

month period between the effective date and the start of the submission
period.
    EPA is also asking for public comment on the submission period
start date and duration (see Unit V.).

C. What information would be reported?

    TSCA section 8(a)(7) specifies that, under the final rule,
manufacturers would report on ``information described in subparagraphs
(A) through (G) of paragraph (2) [of section 8].'' Therefore, this TSCA
section 8(a)(7) rule proposes one-time reporting of the information
described in section 8(a)(2)(A) through (G), which includes specific
chemical identity, categories of use, production volume, byproducts,
environmental and health effects, number of persons exposed and
duration of exposure, and disposal.
    Specifically, EPA is proposing to request the following
information:
    1. Chemical name (multiple if mixture), or the generic name(s) if
the chemical name(s) is CBI.
    2. Chemical ID(s) (CASRN, TSCA Accession Number, or LVE case
number).
    3. Trade name or common name.
    4. Representative molecular structure.
    5. Physical form of chemical or mixture.
    6. Industrial processing and use:
    a. Type of process or use;
    b. Sector(s);
    c. Functional use category(ies);
    d. Percent of production volume for each use.
    7. Consumer and commercial use:
    a. Indicator for whether this is a consumer and/or commercial
product;
    b. Product category; functional use category(ies);
    c. Percent production volume for each use; maximum concentration in
any product;
    d. Indicator for use in products intended for children.
    8. Production volumes:
    a. Domestically manufactured;
    b. Imported;
    c. Directly exported;
    d. Maximum first 12 months production volume;
    e. Maximum yearly production volume in any 3 years.
    9. Indicator for imported but never physically at site.
    10. Indicator for site-limited.
    11. Maximum quantity stored on-site at any time.
    12. Total volume recycled (on-site).
    13. For byproducts produced during the manufacture, processing,
use, or disposal of each PFAS:
    a. Chemical name(s) or description (if identity is unknown), or the
generic name(s) if the byproduct name(s) is CBI;
    b. Chemical ID(s) (CASRN, TSCA Accession Number, or LVE case
number);
    c. Indicator for whether the byproduct(s) production resulted from
manufacture, process, use, or disposal; and
    d. Indicator for whether the byproduct(s) is released to the
environment; if so, volume of byproduct(s) released and to which
environmental media.
    14. Worker exposure: Description of worker activity(ies) at
manufacturing site.
    15. Worker exposure at the manufacturing site:
    a. Number of workers reasonably likely to be exposed at the
manufacturing site, for each worker activity;
    b. Maximum duration of exposure for any worker, for each worker
activity (both hours per day and days per year).
    16. Worker exposure for each industrial process and use:
    a. Number of workers reasonably likely to be exposed for each
industrial process and use;
    b. Maximum duration of exposure for any worker for each industrial
process and use (both hours per day and days per year).
    17. Worker exposure for each commercial use:
    a. Number of workers reasonably likely to be exposed for each
commercial use;
    b. Maximum duration of exposure for any worker for each commercial
use (both hours per day and days per year).
    18. Description of disposal process(es), and description of any
changes to the disposal process or methods since 2011.
    19. Total volume released:
    a. Land disposal;
    b. Water releases;
    c. Air releases.
    20. Total volume incinerated (on-site) and incineration
temperature.
    21. All existing information related to health and environmental
effects, using the Organization of Economic Cooperation and Development
(OECD) harmonized template relevant to the existing study, as well as
full study reports and any other supporting information (for additional
information on the use of the OECD harmonized templates, see the
discussion in the following section, Unit III.D.).
    22. Other data relevant to health and environmental effects (e.g.,
range-finding studies, preliminary studies, OSHA medical screening or
surveillance standards reports, adverse effects reports).
    A list of the proposed reporting requirements is available in the
docket for public review (Ref. 10).
    EPA developed an information reporting platform for CDR (Ref. 9)
and intends to modify it for purposes of this proposed rule. Certain
information that is requested in the CDR that falls under TSCA section
8(a)(2)(A) through (G) would be required by this proposed rule, such as
information on specific chemical identity, categories of use,
production volume, byproducts, and number of persons exposed and
duration of exposure (see Unit III.A.2. for the discussion on
duplicative reporting). In instances where PFAS manufacturers under
this proposed rule have already reported the requested information to
EPA, they will not be required to re-report. As discussed in Unit
III.A.2, EPA is proposing the reporters simply indicate they have
already submitted such information to EPA.
    Additionally, any person required to report under this proposed
rule would supply the information identified in the form to the extent
it is known to or reasonably ascertainable by them, or a reasonable
estimate when actual data are not available (i.e., known or reasonably
ascertainable), as explained in more detail in Unit II.D.

D. What type of environmental and health effects information is the
Agency requesting?

    EPA is requesting ``all existing information concerning the
environmental and health effects'' of the PFAS chemicals covered by
this rule. It is intended that ``environmental and health effects
information'' be interpreted broadly. This information would include
but is not limited to:
     Toxicity information (e.g., in silico, in vitro, animal
test results, human data); and
     Other data relevant to environmental and health effects
including range-finding studies, preliminary studies, OSHA medical
screening or surveillance standards reports, adverse effects reports.
    Chemical identity is always part of a health and safety study, and
TSCA section 14(b) limits the extent to which health and safety studies
and information from studies may be withheld from the public as
confidential.
    EPA is proposing to require all existing information concerning
health and environmental effects be submitted in the format of OECD
harmonized templates, where such templates exist for the type of data,
in addition to submitting full study reports. OECD

templates are accessible to the public online at https://www.oecd.org/ehs/templates/harmonised-templates.htm (Ref. 11). A standardized format
such as the OECD templates will improve the efficiency of review and
organization of the submitted data. EPA believes that some of the data
will already be in the OECD template if the company had already
submitted the studies under the European Union's Registration,
Evaluation, Authorization and Restriction of Chemicals (REACH)
regulation. In addition to the required template format, those subject
to this rulemaking must submit any associated full study reports or
underlying data as support documents. The full study reports and
support documents are necessary for EPA to understand the full context
and evaluate the quality of the data, which is necessary for the Agency
to review if data were to be used for any future Agency actions.
    EPA is requesting comments on what environmental and health effects
information should be within the scope of this rule. EPA is also
requesting comment on whether any information proposed to be requested
is duplicative of information collected by EPA under other federal
statutes and, thus, should be excluded. Please identify the information
that you believe is duplicative and the statute under which it is
submitted.

E. How would information be submitted to EPA?

    EPA is proposing to require electronic reporting similar to the
requirements established in 2013 for submitting other information under
TSCA (see 40 CFR 704.20(e)). EPA is proposing to require submitters to
use EPA's CDX, the Agency's electronic reporting portal, for all
reporting under this rule. In 2013, EPA finalized a rule to require
electronic reporting of certain information submitted to the Agency
under TSCA sections 4, 5, 8(a) and 8(d) (Ref. 12, page 72818). The
final rule followed two previous rules requiring similar electronic
reporting of information submitted to EPA for TSCA CDR and for PMNs. In
proposing to require similar electronic reporting under this rule, EPA
intends to save time, improve data quality and increase efficiencies
for both the submitters and the Agency.
    EPA developed the Chemical Information Submission System (CISS) for
use in submitting data electronically to the Agency for TSCA sections
4, 5, 6, 8(a), 8(b), 8(d), 8(e), and Title VI. CISS, a web-based
reporting tool housed within the CDX environment, provides submitters
with user-friendly applications to build and submit data packages to
EPA within a secure, encrypted environment. CISS applications provide
for the capture of both fielded data as well as the attachment of
additional information using a wide variety of file types. Submitted
information is rendered into PDF and XML formats, which are provided to
submitters in the form of a Copy of Record.
    EPA is proposing to require submitters to follow the same
submission procedures used for other TSCA submissions, i.e., to
register with EPA's CDX and use CISS to prepare a data file for
submission. Registration enables CDX to authenticate user identity. To
submit electronically to EPA via CDX, individuals must first register
with CDX at http://cdx.epa.gov/. To register in CDX, the CDX registrant
(also referred to as ``Electronic Signature Holder'' or ``Public/
Private Key Holder'') agrees to the Terms and Conditions, provides
information about the submitter and organization, selects a user name
and password, and follows the procedures outlined in the guidance
document for CDX available at https://cdx.epa.gov/FAQ#CSPP.
    Within CDX, CISS is available under the ``Submission for Chemical
Safety and Pesticide Program (CSPP)'' CDX flow. Users who have
previously submitted under TSCA through CDX, including submitting
information under sections 4 and 5, CDR, or reporting under the TSCA
Inventory Notification (Active-Inactive) Requirements rule (82 FR
37520, Aug. 11, 2017) (FRL-9964-22), will already have the CSPP flow
linked to their account. Users reporting to EPA using other CDX housed
applications, including the Toxics Release Inventory TRI-MEweb, would
be able to add the CSPP flow to their existing CDX accounts.
    All submitters would be required to use CISS to prepare their
submissions. CISS guides users through a ``hands-on'' process of
creating an electronic submission. Once a user completes the relevant
data fields and attaches appropriate PDF files, or other file types,
such as XML files, the web-based tool validates the submission by
performing a basic error check and makes sure all the required fields
and attachments are provided and complete. Further instructions for
uploading PDF attachments or other file types, such as XML, and
completing metadata information would be available through CISS
reporting guidance.
    CISS, a web-based reporting tool, also allows the user to choose to
``Preview,'' ``Save,'' or ``Submit'' the data package. Once the
submission process is initiated, the user is asked to certify the
information and provide requested information to complete the
submission process. The data package is then sent, in an encrypted
state, to the Agency. The user can login to the application and check
the submission status of their data package. Upon successful receipt of
the submission by EPA, the submission status of the submissions will be
flagged as ``Completed'' and a confirmation email will be sent to the
submitter's CDX inbox. The CDX inbox is used to notify the users when
submissions are received by EPA or to notify users when a submission-
specific communication has been received and how to locate and access
the communication. Information on accessing the CDX user inbox is
provided in the guidance document for CDX at https://cdx.epa.gov/FAQ#CSPP. To access CISS log into CDX using the link: https://cdx.epa.gov/ and click on the appropriate user role associated with the
CSPP data flow. For further instructions, visit https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/electronic-reporting-requirements-certain-information (Ref. 12). Procedures for reporting
chemical substances under this proposed rule would be similar.
    EPA believes that electronic reporting reduces the reporting burden
for submitters by reducing the cost and time required to review, edit,
and transmit data to the Agency. It also allows submitters to share a
draft submission within their organization, and more easily save a copy
for their records or future use. Additionally, EPA believes that many
of the anticipated reporters under this proposed rule have experience
with reporting electronically to EPA through CDX. The resource and time
requirements to review and process data by the Agency will also be
reduced and document storage and retrieval will require fewer
resources. EPA expects to benefit from receiving electronic submissions
and communicating electronically with submitters.

F. What can a submitter claim as confidential?

    The 2016 amendments to TSCA included new procedural requirements
for the submission and Agency management of CBI claims, including new
substantiation requirements, generic name requirements, a certification
requirement, and a requirement for Agency review of specified CBI
claims within 90 days after receipt of the claim, 15 U.S.C. 2613. The
Agency recently finalized a rule amending the CDR reporting
requirements that implemented the new requirements for confidentiality
claims

in CDR submissions (Ref. 13). EPA is similarly proposing that a person
submitting a reporting form under this action may claim portions of the
form as confidential, consistent with TSCA section 14. TSCA requires
that the submitter make several statements relating to the treatment of
the information as confidential and competitive harm of disclosure, and
to certify that these statements and any substantiation provided are
true and correct. Consistent with the format of other TSCA reporting
forms, the statements and certification would be combined into a single
certification statement. There is also a requirement that when a
chemical identity is claimed as CBI, a non-CBI structurally descriptive
generic name be provided. To help reporters, EPA's reporting platform
can auto-populate generic names on the Inventory using EPA's Substance
Registry Services (SRS).
    TSCA section 14 further requires that substantiation be provided
when a confidentiality claim is asserted. However, TSCA section
14(c)(2) exempts certain information from the substantiation
requirements (e.g., specific production volume). Under the proposed
rule, specific production or import volumes of the manufacturer, as
well as the percent production volume for each consumer or commercial
use, need not be substantiated. All other information submitted under
this proposed rule would not be exempt from substantiation
requirements.
    Any information which is claimed as confidential will be disclosed
by EPA only in accordance with the procedures and requirements of TSCA
section 14 and 40 CFR part 2. TSCA limits confidentiality protections
for health and safety studies, information from health and safety
studies (except to the extent such studies or information reveals
``information that discloses processes used in the manufacturing or
processing of a chemical substance or mixture or, in the case of a
mixture, the portion of the mixture comprised by any of the chemical
substances in the mixture''), and certain other information. Submitters
asserting a confidentiality claim for such information in health and
safety studies will be required to submit a sanitized copy of the
study, removing only that information which is claimed as confidential
and that discloses the process or portion of mixture information
described in TSCA section 14(b).

G. What are the recordkeeping requirements?

    EPA proposes that each person who is subject to the reporting
requirements must retain records that document any information reported
to EPA. Consistent with the CDR rule, EPA is proposing a five-year
recordkeeping period, beginning on the last date of the submission
period. The five-year retention requirement corresponds with the
statute of limitations for violations and is necessary to preserve
records to support future regulatory activities that would be informed
by this information collection. Further, EPA believes the burden of
retaining these records, which are likely electronic, is minimal.

IV. Request for Comments

    EPA is seeking public comment on all aspects of this proposed rule
and the Economic Analysis prepared in support of this proposed rule
(Ref. 14). In addition to specific requests for comment included
throughout this document, EPA is interested in comments pertaining to
the specific issues discussed in this unit. EPA encourages all
interested persons to submit comments on the issues identified in this
Notification and to identify any other relevant issues as well. This
input will assist the Agency in developing a final rule that
successfully addresses information needs while minimizing potential
reporting burdens associated with the rule. EPA requests that
commenters making specific recommendations include supporting
documentation where appropriate.
    1. Identifying the chemical substances that would be subject to
reporting. EPA has provided a structural definition of PFAS for the
purposes of this proposed rule's scope. To assist reporting entities
with determining whether a chemical substance or mixture falls within
this scope, EPA has also provided a list of PFAS (identified by CASRN,
TSCA Accession Number, or LVE case number) and structural diagrams to
include any PFAS whose chemical identity is not specifically listed due
to CBI protections. EPA is soliciting comment on this approach for
defining or identifying PFAS. Additionally, EPA is interested in
comments identifying specific substances of interest and the rationale
for the interest, that may be outside the scope of this proposed
definition. EPA is also interested in public comments related to
including imported articles containing PFAS within the scope of this
proposed rule.
    2. Considerations for the Agency's economic analysis. EPA has
evaluated the potential costs for PFAS manufacturers for this proposed
rule (Ref. 14). EPA is specifically seeking additional information and
data that EPA could consider in developing the final economic analysis.
In particular, EPA is seeking data that could facilitate the Agency's
further evaluation of the potentially affected industry and firms,
including data related to potential impacts for those small businesses
and importers that would be subject to reporting. The agency is
specifically interested in available data on small entity importers of
articles containing PFAS for its impact analysis for small entities.
EPA is also especially interested in available data or other measures
of the number of facilities or firms that might manufacture such
materials, including importing PFAS in articles.
    3. Submission period. EPA is proposing a six-month submission
period for reporting entities, which will begin six months following
the effective date of the final rule. Thus, PFAS manufacturers will
have one year following the effective date of the final rule to submit
all required information to EPA. Since many of the reporters under this
proposed rule have reported under CDR, EPA is basing the proposed
submission period, in part, on the CDR submission period. Given the
four-month submission period for the CDR reporting cycle every four
years, the Agency believes six months is sufficient time for
manufacturers to report the required information under this proposed
rule, noting that the scope of this rule covers more years than a CDR
reporting cycle. Reporters will also have the additional six months
between the effective date of the rule and the start of the submission
period for rule familiarization and data gathering. Additionally, the
six months between the effective date of the final rule and the
beginning of the submission period allows the Agency time to finalize
the reporting software. Congress required EPA to promulgate the rule no
later than January 1, 2023; therefore, EPA anticipates the reporting
period for this proposed rule will precede the reporting period for the
2024 CDR reporting cycle (June-September 2024). EPA is specifically
asking for comment on additional considerations related to the start
date and duration of the submission period.
    4. Duplicative reporting. EPA has identified the data elements in
this proposed rule for which information may have been submitted to EPA
previously under CDR (see Unit III.D.), which the Agency is proposing
to allow manufacturers to indicate through the

reporting tool has already been submitted rather than re-submit the
information. EPA is requesting comment on whether any additional data
elements may be duplicative of information collected by EPA under TSCA
or other federal statutes. Please identify the information that you
believe is duplicative and the statute under which it is submitted, as
well as the precision of the information if appropriate (for example,
whether the data are submitted as a range or as an integer to the
nearest significant digits).
    5. Scope of environmental and health effects information collected.
EPA is requesting comment on what existing environmental and health
effects information should be within the scope of this rule. EPA is
proposing to require such information be submitted in the form of OECD
harmonized templates, to the extent they are available, and as full
study reports and any supporting documents. The Agency is requesting
comments on the scope of existing environmental and health information
that may be requested from PFAS manufacturers. The Agency is also
interested in comments on the proposed format of these submissions.
    6. Additional information or data elements. EPA has provided the
list of proposed data elements for this rule in Unit III.C (Ref. 10),
which EPA is authorized to request under section 8(a)(7). EPA is
interested in public comment on the scope of these proposed data
elements, including whether there are additional data elements EPA
should collect under the authority of section 8(a)(7). Specifically,
EPA is interested in comments on whether the final rule should include
a data field allowing reporters to provide generic names or
descriptions in the event a manufacturer is aware they have produced or
imported a PFAS but are not able to reasonably ascertain the specific
PFAS identity. The Agency is also requesting comments on additional
data elements such as composition information if a PFAS has a variable
composition, analytical methods, and whether occupational exposure
information should distinguish occupational non-users (i.e., those
nearby but not in direct contact with the chemical) from workers (i.e.,
those who are in direct contact with the chemical).
    7. EPA's use and publication of certain non-CBI data. EPA is
requesting public comment on how the Agency may consider using the data
received under this reporting rule, beyond those activities previously
mentioned in Unit II.E. Additionally, the Agency is interested in
comment on the extent to which non-CBI data submitted under this rule
should be provided to the general public.
    8. Joint submissions. EPA is requesting public comment on whether
the Agency should enable the use of joint submissions in specific
circumstances, similar to CDR joint submissions. Joint submissions may
be necessary under circumstances when: (1) A company imports a chemical
or a mixture under a trade name and the substance identity, or
individual components, are not known to the importer, or (2) a
manufacturer cannot provide the entire chemical identity of a chemical
substance it manufactures because the chemical substance is
manufactured using a reactant having an identity that the reactant
supplier claims as confidential. In these circumstances, the supplier
has identified that it will not disclose to the manufacturer (or
importer) or does not, itself, know the chemical identity.
    9. Small manufacturers. EPA is requesting public comment on how the
Agency may assist small manufacturers with compliance with this
proposed rule. The Agency appreciates comments related to both
regulatory and non-regulatory assistance, such as different reporting
timelines and outreach.

VII. 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). EPA prepared an analysis of the estimated costs and
benefits associated

with this action (Ref. 13), which is available in the docket and is
summarized in Unit I.E. 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.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have
been submitted for approval to the Office of Management and Budget
(OMB) under the PRA, 44 U.S.C. 3501 et seq. The Information Collection
Request (ICR) document that EPA prepared has been assigned EPA ICR
number 2682.01 (Ref. 15). You can find a copy of the ICR in the docket
for this rule, and it is briefly summarized here.
    The reporting requirements identified in the proposed rule would
enable EPA to meet the statutory obligations required by TSCA section
8(a)(7) and collect data related to the identities, manufacture, use,
exposure, and disposal of PFAS manufactured in the United States since
2011. These proposed reporting requirements would also help the Agency
to collect existing information on the health and environmental effects
of PFAS. EPA intends to use information collected under the rule to
assist in chemical assessments under TSCA, and to inform any additional
work necessary under environmental protection mandates beyond TSCA.
Respondents may claim some of the information reported to EPA under the
proposed rule as CBI under TSCA section 14. TSCA section 14(c) requires
a supporting statement and certification for confidentiality claims
asserted after June 22, 2016.
    Respondents/affected entities: Manufacturers (including importers)
of PFAS since January 1, 2011.
    Respondent's obligation to respond: Mandatory (15 U.S.C.
2607(a)(7)).
    Estimated number of respondents: 234.
    Frequency of response: Once.
    Total estimated burden: 122,104 hours (per year). Burden is defined
at 5 CFR 1320.3(b).
    Total estimated cost: $9,820,813 (per year), includes no annualized
capital or operation and maintenance costs.
    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's 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 rule. You may also send your ICR-related comments
to OMB's Office of Information and Regulatory Affairs via email to
<EMAIL_ADDRESS>Attention: Desk Officer for the EPA.
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 July
28, 2021. The 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 manufacturers (including importers) of PFAS. EPA
estimates that 59 small firms would be affected by the proposed rule.
Of those small firms, 46% would have cost impacts of less than 1% of
annual revenues, 19% would have impacts between 1-3%, and 35% would
have impacts of more than 3% of annual revenues. The affected small
businesses subject to the proposed rule are expected to incur
$1,788,506 in costs for this one-time reporting, with per-firm costs
estimated to range from $16,864 to $92,390. However, EPA is unable to
estimate the number of small entity importers of articles that are
subject to this proposed rule due to a lack of available data on
importers of articles containing PFAS. Imported articles are exempt
from the CDR Rule under 40 CFR 711.10(b). Similarly, under TRI
reporting, listed toxic chemicals contained in articles that are
processed or otherwise used at a covered facility are exempt from
reporting threshold determinations and release and other waste
management calculations. EPA is unaware of publicly available data that
provides the information on the article importers needed to develop the
estimates. Without available data, EPA does not have a representative
subset of firms to reference as a basis for estimates and thus cannot
estimate the number of importers of articles that will be affected.
    However, EPA expects that article importers may incur a range of
costs depending on the number of articles they import, their level of
knowledge of their imported articles, the complexity of supply chains,
and whether PFAS is present in their articles. Importers of articles
that contain PFAS may incur costs for rule familiarization ($69.79 per
firm); identifying the type of imported articles that potentially use
PFAS ($1,641-$1,932 per firm); identifying suppliers involved ($1,185
per firm); collecting data from suppliers ($0-644 per article); and
recordkeeping ($12 per firm). Details of this analysis are presented in
the Economic Analysis of the proposed rule (Ref. 14), which is
available in the docket.

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. The requirements of
this action would primarily affect manufacturers (including importers)
of PFAS. The total quantified one-time costs of the proposed rule are
approximately $9.8 million.

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). It will not have
substantial direct effects 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. Thus, E.O. 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 the Agency 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 a covered regulatory action because it is not
``economically significant'' under Executive Order 12866 and it does
not concern an environmental health risk or safety risk. Although this
action would not establish an environmental standard

intended to mitigate health or safety risks, the information that would
be submitted to EPA in accordance with this proposed rule would be used
to inform the Agency's decision-making process regarding chemical
substances to which children may be disproportionately exposed. This
information may also assist the Agency and others in determining
whether the chemical substances covered in this proposed rule present
potential risks, which would allow the Agency and others to take
appropriate action to investigate and mitigate those 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 defined 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 OMB's Office of Information and Regulatory Affairs
as a ``significant energy action.''

I. National Technology Transfer and Advancement Act (NTTAA)

    Because this action does not involve any technical standards, 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

    EPA believes that this action does not have disproportionately high
and adverse human health or environmental effects on minority
populations, low-income populations and/or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).
    The requirements of the proposed rule are directed at manufacturers
(including importers) of PFAS chemicals for which basic production,
use, and toxicity information is currently unavailable. The costs and
the benefits of the proposed rule would not be disproportionately
distributed across different geographic regions or among different
categories of individuals. Consumers of these chemical products,
workers who come into contact with these chemical substances, and
communities neighboring PFAS manufacturing sites could benefit from
EPA's assessment of information required under the proposed rule. The
Agency believes that the information collected under this proposed
rule, if finalized, will assist EPA and others in determining the
potential hazards and risks associated with PFAS chemicals. Although
not directly impacting environmental justice-related concerns, this
information will enable the Agency to better protect human health and
the environment, including in low-income and minority communities.

manufacturers (including importers) of certain per- and polyfluoroalkyl
substances (hereafter referred to as PFAS) under section 8(a)(7) of the
Toxic Substances Control Act (TSCA).

Sec.  705.3   Definitions.

    Central Data Exchange or CDX means EPA's centralized electronic
submission receiving system.
    Chemical Information Submission System or CISS means EPA's
electronic, web-based reporting tool for the completion and submission
of data, reports, and other information, or its successors.
    Commercial use means the use of a chemical substance or a mixture
containing a chemical substance (including as part of an article) in a
commercial enterprise providing saleable goods or services.
    Consumer use means the use of a chemical substance or a mixture
containing a chemical substance (including as part of an article) when
sold to or made available to consumers for their use.
    Environmental or health effects information means any information
of any effect of a chemical substance or mixture on health or the
environment or on both. This includes all health and safety studies.
    (1) Not only is information which arises as a result of a formal,
disciplined study included, but other information relating to the
effects of a chemical substance or mixture on health or the environment
is also included. Any information that bears on the effects of a
chemical substance on health or the environment would be included.
    (2) Examples are:
    (i) Long- and short-term tests of mutagenicity, carcinogenicity, or
teratogenicity; data on behavioral disorders; dermatoxicity;
pharmacological effects; mammalian absorption, distribution,
metabolism, and excretion; cumulative, additive, and synergistic
effects; and acute, subchronic, and chronic effects.
    (ii) Tests for ecological or other environmental effects on
invertebrates, fish, or other animals, and plants, including: Acute
toxicity tests, chronic toxicity tests, critical life-stage tests,
behavioral tests, algal growth tests, seed germination tests, plant
growth or damage tests, microbial function tests, bioconcentration or
bioaccumulation tests, and model ecosystem (microcosm) studies.
    (iii) Assessments of human and environmental exposure, including
workplace exposure, and impacts of a particular chemical substance or
mixture on the environment, including surveys, tests, and studies of:
Biological, photochemical, and chemical degradation; structure/activity
relationships; air, water, and soil transport; biomagnification and
bioconcentration; and chemical and physical properties, e.g., boiling
point, vapor pressure, evaporation rates from soil and water, octanol/
water partition coefficient, and water solubility.
    (iv) Monitoring data, when they have been aggregated and analyzed
to measure the exposure of humans or the environment to a chemical
substance or mixture.
    Health and safety studies means any study of any effect of a
chemical substance or mixture on health or the environment or on both,
including underlying information and epidemiological studies, studies
of occupational exposure to a chemical substance or mixture,
toxicological, clinical, and ecological studies of a

chemical substance or mixture, and any test performed pursuant to this
Act.
    Known to or reasonably ascertainable by means all information in a
person's possession or control, plus all information that a reasonable
person similarly situated might be expected to possess, control, or
know.
    Industrial function means the intended physical or chemical
characteristic for which a chemical substance or mixture is consumed as
a reactant; incorporated into a formulation, mixture, reaction product,
or article; repackaged; or used.
    Industrial use means use at a site at which one or more chemical
substances or mixtures are manufactured (including imported) or
processed.
    Intended for use by children means the chemical substance or
mixture is used in or on a product that is specifically intended for
use by children age 14 or younger. A chemical substance or mixture is
intended for use by children when the submitter answers ``yes'' to at
least one of the following questions for the product into which the
submitter's chemical substance or mixture is incorporated:
    (1) Is the product commonly recognized (i.e., by a reasonable
person) as being intended for children age 14 or younger?
    (2) Does the manufacturer of the product state through product
labeling or other written materials that the product is intended for or
will be used by children age 14 or younger?
    (3) Is the advertising, promotion, or marketing of the product
aimed at children age 14 or younger?
    Manufacture means to manufacture for commercial purposes.
    Manufacture for commercial purposes means: (1) To import, produce,
or manufacture with the purpose of obtaining an immediate or eventual
commercial advantage for the manufacturer, and includes among other
things, such ``manufacture'' of any amount of a chemical substance or
mixture:
    (i) For commercial distribution, including for test marketing.
    (ii) For use by the manufacturer, including use for product
research and development, or as an intermediate.
    (2) Manufacture for commercial purposes also applies to substances
that are produced coincidentally during the manufacture, processing,
use, or disposal of another substance or mixture, including both
byproducts that are separated from that other substance or mixture and
impurities that remain in that substance or mixture. Such byproducts
and impurities may, or may not, in themselves have commercial value.
They are nonetheless produced for the purpose of obtaining a commercial
advantage since they are part of the manufacture of a chemical product
for a commercial purpose.
    Manufacturer means a person who manufactures a chemical substance.
    Per- and polyfluoroalkyl substances or PFAS, for the purpose of
this part, means any chemical substance or mixture that structurally
contains the unit R-(CF2)-C(F)(R')R''. Both the CF2 and CF moieties are
saturated carbons. None of the R groups (R, R' or R'') can be hydrogen.
    Site-limited means a chemical substance is manufactured and
processed only within a site and is not distributed as a chemical
substance or as part of a mixture or article outside the site. Imported
chemical substances are never site-limited.
    Worker means someone at a site of manufacture, import, or
processing who performs work activities near sources of a chemical
substance or mixture or directly handles the chemical substance or
mixture during the performance of work activities.

Sec.  705.5   Substances for which reports must be submitted.

    The requirements of this part apply to all chemical substances and
mixtures that are PFAS, consistent with the definition of PFAS at Sec.
705.3. This includes, but is not limited to, all PFAS listed or
