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 Perand 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 consider to be 

Confidential Business Information (CBI) 

or other information whose disclosure is 

restricted by statute. 

Due to the public health concerns 

related to COVID–19, the EPA Docket 

Center (EPA/DC) and Reading Room is

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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 33927 

(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 onetime 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

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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 33929 

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 lowvolume 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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
33930 Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 

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 sixVerDate Sep<11>2014 16:20 Jun 25, 2021 Jkt 253001 PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 E:\FR\FM\28JNP1.SGM 28JNP1

khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 33931 

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., rangefinding 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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
33932 Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 

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-chemicalsunder-tsca/electronic-reportingrequirements-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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 33933 

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 fourmonth 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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
33934 Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 

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 nonregulatory 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/lawsregulations/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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 33935 

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 oira_

submissions@omb.eop.gov, 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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
33936 Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 

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, lowincome 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.

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. 

§ 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 § 705.3. This 

includes, but is not limited to, all PFAS 

listed or otherwise described in this 

section. This section contains 5 listings 

of examples of chemical substances or 

mixtures that meet this definition. 

Paragraph (a) of this section is a list of 

chemical substances on the TSCA 

Inventory that have an associated 

Chemical Abstract Services (CAS) 

Registry Number. Paragraph (b) of this 

section is a list of chemical substances 

that have an associated TSCA Accession 

Number. Paragraph (c) of this section is 

a list of chemical substances that have 

both an associated low-volume 

exemption (LVE) case number and a 

non-confidential CASRN. Paragraph (d) 

of this section is a list of chemical 

substances with an LVE case number 

but no CASRN. Paragraph (e) of this 

section is a list of structural diagram 

examples of PFAS and those CASRNs.

Index name as used to list the chemical 

substance on the TSCA Inventory and 

the correct corresponding CASRN for 

each reportable PFAS at each site. 

Submitters who wish to report chemical 

substances listed on the confidential 

portion of the TSCA Inventory will need 

to report the chemical substance using 

a TSCA Accession Number. If a 

submitter has a low-volume exemption 

(LVE) case number for the chemical 

substance, that number may also be 

used if a CASRN is not known to or 

reasonably ascertainable by the 

submitter. 

(ii) In addition to reporting the 

number itself, submitters must specify 

the type of number they are reporting by 

selecting from among the codes in Table

the manufacture, processing, use, or 

disposal of a PFAS, the submitter will 

identify the byproduct by its specific, 

currently correct CA Index name as 

used to list the chemical substance on 

the TSCA Inventory and the correct 

corresponding CASRN. A submitter 

under this part may use an EPAdesignated TSCA Accession Number for 

a chemical substance in lieu of a 

CASRN when a CASRN is not known to 

or reasonably ascertainable by the 

submitter. Submitters who wish to 

report chemical substances listed on the 

confidential portion of the TSCA 

Inventory will need to report the 

chemical substance using a TSCA 

Accession Number. 

(i) In addition to reporting the number 

itself, submitters must specify the type 

of number they are reporting by 

selecting from among the codes in Table 

1 of paragraph (b)(1)(i) of this section. 

(ii) If the specific identity of the 

byproduct is unknown to the submitter, 

the submitter may provide a description 

of the chemical substance. 

(iii) An indication of which specific 

PFAS activity(ies) (i.e., manufacture, 

process, use, or disposal) manufactured 

the byproduct.

§ 705.30 Confidentiality claims. 

(a) Making confidentiality claims—(1) 

Generally. Any person submitting 

information under this part may assert 

a confidentiality claim for that 

information, except for information 

described in paragraph (a)(2) of this 

section. Any such confidentiality claims 

must be asserted at the time the 

information is submitted. Instructions 

for asserting confidentiality claims are 

provided in the document identified in 

§ 705.35. Information claimed as 

confidential in accordance with this 

section will be treated and disclosed in 

accordance with the procedures in 40 

CFR part 2 and section 14 of TSCA. 

(2) Exceptions. Confidentiality claims 

cannot be asserted: 

(i) For chemical identities listed on 

the public portion of the TSCA 

Inventory; 

(ii) For processing and use data 

elements required by § 705.15(c)(1) 

through (7); or 

(iii) When a response is left blank or 

designated as ‘‘not known or reasonably 

ascertainable.’’ 

(3) Health and environmental effects 

information. Any person submitting 

health and effects information under 

this part may only assert a 

confidentiality claim for information 

that ‘‘discloses processes used in the 

manufacturing or processing of a 

chemical substance or mixture or, in the 

case of a mixture, the release of data 

disclosing the portion of the mixture 

comprised by any of the chemical 

substances in the mixture.’’ If any such

person who submits the information 

must also provide EPA with a sanitized 

copy for public release, removing only 

that information that is claimed as 

confidential. 

(b) Unless exempted, all 

confidentiality claims require 

substantiation at time of submission 

and must be signed and dated by an 

authorized official. Confidentiality 

claims for the following data elements 

are exempt from this substantiation 

requirement: 

(1) Production volume information 

required pursuant to § 705.15(d)(1), (5), 

and (6). 

(c) Marking information claimed as 

confidential in confidentiality 

substantiation documentation. If any of 

the information contained in the 

answers to the questions listed in 

paragraph (e) of this section is asserted 

to contain information that itself is 

considered to be confidential, you must 

clearly identify the information that is 

claimed confidential. 

(d) Certification statement for claims. 

An authorized official representing a 

person asserting a claim of 

confidentiality must certify that the 

submission complies with the 

requirements of this part by signing and 

dating the following certification 

statement: 

‘‘I certify that all claims for 

confidentiality asserted with this 

submission are true and correct, and all 

information submitted herein to 

substantiate such claims is true and 

correct. Any knowing and willful 

misrepresentation is subject to criminal 

penalty pursuant to 18 U.S.C. 1001. I 

further certify that: (1) I have taken 

reasonable measures to protect the 

confidentiality of the information; (2) I 

have determined that the information is 

not required to be disclosed or 

otherwise made available to the public 

under any other Federal law; (3) I have 

a reasonable basis to conclude that 

disclosure of the information is likely to 

cause substantial harm to the 

competitive position of my company; 

and (4) I have a reasonable basis to 

believe that the information is not 

readily discoverable through reverse 

engineering.’’ 

(e) Substantiation requirements for all 

types of confidentiality claims. For each 

data element that is claimed as 

confidential, you must submit with your 

report detailed written answers to the 

following questions: 

(1) Will disclosure of the information 

claimed as confidential likely cause 

substantial harm to your business’s 

competitive position? If you answered 

yes, describe the substantial harmful 

effects that would likely result to your 

competitive position if the information 

is disclosed, including but not limited 

to how a competitor could use such 

information, and the causal relationship 

between the disclosure and the harmful 

effects. 

(2) Has your business taken 

precautions to protect the 

confidentiality of the disclosed 

information? If yes, please explain and 

identify the specific measures, 

including but not limited to internal 

controls, that your business has taken to 

protect the information claimed as 

confidential. 

(3)(i) Is any of the information 

claimed as confidential required to be 

publicly disclosed under any other 

Federal law? If yes, please explain. 

(ii) Does any of the information 

claimed as confidential otherwise 

appear in any public documents, 

including (but not limited to) safety data 

sheets; advertising or promotional 

material; professional or trade 

publications; state, local, or Federal 

agency files; or any other media or 

publications available to the general 

public? If yes, please explain why the 

information should be treated as 

confidential. 

(iii) Does any of the information 

claimed as confidential appear in one or 

more patents or patent applications? If 

yes, please provide the associated patent 

number or patent application number 

(or numbers) and explain why the 

information should be treated as 

confidential. 

(4) Does any of the information that 

you are claiming as confidential 

constitute a trade secret? If yes, please 

explain how the information you are 

claiming as confidential constitutes a 

trade secret. 

(5) Is the claim of confidentiality 

intended to last less than 10 years (see 

TSCA section 14(e)(1)(B))? If yes, please 

indicate the number of years (between 


khammond on DSKJM1Z7X2PROD with PROPOSALS
33966 Federal Register / Vol. 86, No. 121 / Monday, June 28, 2021 / Proposed Rules 

1–10 years) or the specific date after 

which the claim is withdrawn. 

(6) Has EPA, another federal agency, 

or court made any confidentiality 

determination regarding information 

associated with this chemical 

substance? If yes, please provide the 

circumstances associated with the prior 

determination, whether the information 

was found to be entitled to confidential 

treatment, the entity that made the 

decision, and the date of the

(f) Additional requirements for 

specific chemical identity. A person 

may assert a claim of confidentiality for 

the specific chemical identity of a 

chemical substance as described in 

§ 711.15(b) of this part only if the 

identity of that chemical substance is 

treated as confidential in the Master 

Inventory File as of the time the report 

is submitted for that chemical 

substance. Generic chemical identities 

and accession numbers may not be 

claimed as confidential. To assert a 

claim of confidentiality for the identity 

of a reportable chemical substance, you 

must submit with the report detailed 

written answers to the questions from 

paragraph (b) of this section and to the 

following questions. 

(1) Is this chemical substance publicly 

known (including by your competitors) 

to be in U.S. commerce? If yes, please 

explain why the specific chemical 

identity should still be afforded 

confidential status (e.g., the chemical 

substance is publicly known only as 

being distributed in commerce for 

research and development purposes, but 

no other information about the current 

commercial distribution of the chemical 

substance in the United States is 

publicly available). If no, please 

complete the certification statement: 

I certify that on the date referenced, 

I searched the internet for the chemical 

substance identity (i.e., by both 

chemical substance name and CASRN). 

I did not find a reference to this 

chemical substance that would indicate 

that the chemical is being manufactured 

or imported by anyone for a commercial 

purpose in the United States. [provide 

date]. 

(2) Does this particular chemical 

substance leave the site of manufacture 

(including import) in any form, e.g., as 

a product, effluent, emission? If yes, 

please explain what measures have been 

taken to guard against the discovery of 

its identity. 

(3) If the chemical substance leaves 

the site in a form that is available to the 

public or your competitors, can the 

chemical identity be readily discovered 

by analysis of the substance (e.g., 

product, effluent, emission), in light of 

existing technologies and any costs, 

difficulties, or limitations associated 

with such technologies? Please explain 

why or why not. 

(4) Would disclosure of the specific 

chemical name release confidential 

process information? If yes, please 

explain. 

(g) No claim of confidentiality. 

Information not claimed as confidential 

in accordance with the requirements of 

this section may be made public 

without further notice to the submitter.
