Confidential Business Information Claims Under the Toxic 
Substances Control Act (TSCA)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing new and 
amended requirements concerning the assertion and treatment of 
confidential business information (CBI) claims for information reported 
to or otherwise obtained by EPA under the Toxic Substances Control Act 
(TSCA). Amendments to TSCA in 2016 included many new provisions 
concerning the assertion, Agency review, and treatment of 
confidentiality claims. This document proposes procedures for 
submitting such claims in TSCA submissions. It addresses issues such as 
substantiation requirements, exemptions, electronic reporting 
enhancements (including expanding electronic reporting requirements), 
maintenance or withdrawal of confidentiality claims, and provisions in 
current rules that are inconsistent with amended TSCA. The proposed 
rule also addresses EPA procedures for reviewing and communicating with 
TSCA submitters about confidentiality claims.

DATES: Comments must be received on or before July 11, 2022.

SUPPLEMENTARY INFORMATION: 

I. Executive Summary

A. Does this action apply to me?

    You may be affected by this action if you have submitted or expect 
to submit information to EPA under TSCA and have made or expect to make 
any confidentiality claims concerning that information. Persons who 
seek information on such submissions may also be affected by this 
action. The following list of North American Industrial Classification 
System (NAICS) codes is not intended to be exhaustive, but rather 
provides a guide to help readers determine whether this document 
applies to them. Potentially affected entities may include:
     Manufacturers, importers, or processors of chemical 
substances (NAICS codes 325 and 324110), e.g., chemical manufacturing 
and petroleum refineries.
    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.

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

    TSCA section 14, 15 U.S.C. 2613, includes requirements for 
asserting confidentiality claims and for EPA review of such claims to 
determine whether the information is entitled to the requested 
protections. Implementing

[[Page 29079]]

rules are explicitly contemplated for some provisions of TSCA section 
14 (e.g., TSCA section 14(c)(1)(a) requires persons seeking to protect 
information from disclosure to assert such a claim concurrent with 
submission of the information, in accordance with existing or future 
rules; TSCA section 14(c)(3) generally requires that confidentiality 
claims be substantiated ``in accordance with such rules as the 
Administrator has promulgated or may promulgate pursuant to this 
section''). In addition, other TSCA section 14 requirements imply 
authority to promulgate rules addressing the form and manner in which 
those requirements should be fulfilled (e.g., manner of submitting 
confidentiality claims, manner in which EPA will make required notices 
under TSCA sections 14(g) or 14(e)).
    Discussion of authority to require electronic reporting under TSCA 
may be found in the preamble to the final rule entitled ``Electronic 
Reporting under the Toxic Substances Control Act; Final Rule'' (Ref. 
1). In addition, the Government Paperwork Elimination Act (GPEA), 44 
U.S.C. 3504, provides that, when practicable, Federal organizations use 
electronic forms, electronic filings, and electronic signatures to 
conduct official business with the public.

C. What action is the Agency taking?

    EPA is proposing new and amended requirements concerning the 
assertion and treatment of CBI claims under TSCA, 15 U.S.C. 2601, et 
seq. The Frank R. Lautenberg Chemical Safety for the 21st Century Act 
of 2016, Public Law 114-182 (referred to in this Notice as ``the 
Lautenberg amendments''), made significant amendments to TSCA, 
including new provisions governing the assertion and review of CBI 
claims that EPA is proposing to implement in this action.
    In this document, EPA is proposing to specify procedures for 
submitting and supporting CBI claims under TSCA, including among other 
things: (1) Substantiation requirements applicable at the time of 
submission; (2) Electronic reporting requirements; (3) Requirements to 
provide certification statements and generic names when making 
confidentiality claims; (4) Treatment of information used for TSCA 
purposes that EPA could obtain under TSCA but was originally submitted 
via other means; and (5) Maintenance or withdrawal of confidentiality 
claims.
    EPA is also proposing to specify procedures for reviewing and 
communicating with TSCA submitters about confidentiality claims, 
including requirements for submitters to maintain contact information, 
and procedures for EPA to provide notices to submitters concerning 
their claims.
    EPA is proposing new provisions, as well as to amend and reorganize 
existing provisions concerning assertion of confidentiality claims 
under TSCA. Regulatory provisions concerning TSCA CBI claims are 
currently spread over a large number of parts in the Code of Federal 
Regulations (CFR). EPA has general provisions regarding confidentiality 
claims at 40 CFR part 2, subpart B. Those general provisions are 
accompanied by sections pertaining to confidentiality for many of the 
statutes administered by the Agency. The TSCA-specific provisions of 
the Agency's general business confidentiality regulations are at 40 CFR 
2.306. In addition, many of the specific TSCA regulations in title 40 
of the CFR contain their own provisions regarding CBI, such as in parts 
711 (Chemical Data Reporting) and 720 (Premanufacture Notification).
    In this proposed rule, most procedural requirements for asserting 
and maintaining confidentiality claims would be organized into a 
proposed new part of title 40 of the CFR, i.e., in part 703. The 
provisions in proposed part 703 would apply to any TSCA submission, 
except as modified elsewhere in part 2 or other TSCA-specific 
regulations, as spelled out in this proposed rule. Further discussion 
of the interactions between the various provisions regarding 
confidentiality can be found in Unit II.B. of this document.

D. What are the incremental costs and benefits of this action?

    EPA has evaluated the potential incremental impacts of this 
proposed rulemaking, including alternative options. The details are 
presented in the economic analysis prepared for the proposed rule (Ref. 
2), which is available in the docket and is briefly summarized here.
    The benefits of the proposed rule include improvements to EPA's 
management of CBI, specifically in cases of deficient claims, and 
improved communication and increased public transparency for chemical 
information. The proposed rule is expected to decrease the frequency of 
submitter error and increase efficiency in the processes for asserting 
and maintaining CBI claims. Lastly, the proposed rule would bring TSCA 
confidentiality regulations in line with the changes to TSCA section 14 
brought about by the Lautenberg amendments.
    EPA estimates that the public will incur a one-time burden and cost 
of approximately 2,945 hours with an associated cost of approximately 
$271,000 in the first year after the rule is finalized and an annual, 
ongoing burden of approximately 525 hours with an associated cost of 
approximately $45,000 in each following year.

E. Are there potentially disproportionate impacts for children health?

    The proposed rule does not involve environmental health or safety 
risks that the EPA has reason to believe may disproportionately affect 
children. However, the Agency believes that the information collected 
under this proposed rule, if finalized, will assist EPA and others in 
evaluating potential hazards and risks associated with chemicals. 
Although not directly impacting environmental health or safety risks, 
this information will enable the Agency to better protect human health 
and the environment, including the health of children.

F. What are the environmental justice impacts?

    This proposed action does not address human health or environmental 
risks or otherwise have disproportionately high and adverse human 
health or environmental effects on minority populations, low-income 
populations and/or indigenous peoples. Although not directly impacting 
environmental justice-related concerns, the information collected under 
this proposed rule will enable the Agency to better protect human 
health and the environment, including in low-income and minority 
communities.

II. Background

    The Lautenberg amendments included several significant changes to 
TSCA section 14. These include requirements that persons submitting 
information under TSCA substantiate most confidentiality claims at the 
time of submission, as well as additional statement, certification, and 
generic name requirements. Under TSCA section 14(e), in order to 
maintain most claims beyond a 10-year period, submitters are required 
to reassert and resubstantiate those claims. Several new requirements 
also apply to EPA, including requirements at TSCA section 14(g) to 
review and approve or deny all chemical identity claims asserted since 
the Lautenberg amendments were enacted concerning substances that are 
offered for commercial distribution, as well as a subset of all other 
confidentiality claims, within 90 days of assertion of the claim. 
Further requirements that EPA review all confidentiality claims for the 
chemical identity of substances listed as active on the TSCA Inventory, 
a requirement to

[[Page 29080]]

assign and apply unique identifiers (UIDs) to substances with approved 
confidentiality claims for chemical identity, as well as new provisions 
providing expanded access to TSCA CBI, have been discussed in previous 
documents that published in the Federal Register, see e.g., Refs. 3 
(about the CBI review plan), 4 (about UIDs) and 5 (about expanded 
access to CBI). Additionally, some TSCA regulations promulgated or 
amended since the Lautenberg amendments have included confidentiality 
provisions conforming to the amendments (e.g., Chemical Data Reporting 
at 40 CFR 711.30 and Active/Inactive Inventory Reporting at 40 CFR 
710.37).

A. Existing Regulations Governing Confidentiality Under TSCA

    As proposed, this rulemaking would implement additional 
requirements of the Lautenberg amendments concerning confidentiality 
claims and would apply to all TSCA submissions. The proposal is 
intended to clarify the TSCA section 14 requirements for submitters of 
TSCA confidentiality claims. This would reduce the likelihood of claims 
being denied because of procedural insufficiencies and facilitate the 
public availability of information for which confidentiality is either 
not requested or not allowed under TSCA. The proposed procedural rules 
would aid efficient and timely EPA review of confidentiality claims and 
reduce the likelihood of inadvertent disclosure of CBI.
    Currently, CBI claims are asserted according to TSCA section 14 and 
existing TSCA rule requirements that are specific to certain reporting 
requirements (see Unit II.E. of this document). In some cases, further 
claim assertion procedures are included in EPA's general CBI 
regulations at 40 CFR part 2.
    The procedures currently used by EPA to review TSCA CBI claims are 
found in 40 CFR part 2, subpart B. These regulations were developed to, 
among other things, apply Exemption 4 of the Freedom of Information Act 
(FOIA), 5 U.S.C. 552, relating to business confidentiality, to review 
CBI claims in response to a FOIA request. Some TSCA-specific provisions 
in 40 CFR 2.306 add to or modify the general CBI regulations found in 
40 CFR 2.201 through 2.215. 40 CFR 2.306 was last modified in 1993. In 
the absence of revisions to accommodate the changes introduced by the 
Lautenberg amendments, EPA has continued to use the 40 CFR part 2 
regulations to complete the mandatory confidentiality determinations 
required by the Lautenberg amendments.
    The proposed rule would tailor all TSCA CBI claim assertion and 
review procedures to the requirements of TSCA rules and consolidate 
them in the TSCA rules--primarily in the proposed new part 703. 40 CFR 
2.306 would be reduced in scope. It would clarify that most of the 
general claim assertion and review rules found in the 40 CFR part 2 CBI 
rules no longer apply to TSCA CBI claims and to elaborate on special 
circumstances where CBI may be disclosed based on the provisions of 
TSCA section 14(d) (disclosure to states, local governments and tribes 
under TSCA section 14(d)(4); health or environmental professionals 
under TSCA section 14(d)(5); or to certain emergency responders under 
TSCA section 14(d)(6) or as relevant to a proceeding under TSCA section 
14(d)(7)). EPA is proposing to retain certain notice requirements in 40 
CFR part 2 that are not required by TSCA Section 14. Specifically, 
under TSCA section 14(g)(2)(C)(iii), EPA is not required to provide 
notice prior to disclosure of information pursuant to TSCA sections 
14(d)(1), (2), (7), or (8), i.e., to Federal employees or officers, to 
contractors, if relevant to a proceeding, or required to be made public 
under other Federal law. EPA is proposing to retain certain existing 
notice requirements in 40 CFR part 2 for disclosure to Federal 
employees at 40 CFR 2.306(d), if relevant to a proceeding at 40 CFR 
2.306(e), and for contractors and subcontractors at 40 CFR 2.306(f).
    Additionally, the consolidation of TSCA CBI claim review procedures 
into the proposed new part 703 includes the review procedures relating 
to FOIA requests (i.e., CBI claim review required by TSCA section 
14(f)(2)(A)). CBI claim review procedures in 40 CFR 2.306(d), (e), and 
(g), and the procedures in 40 CFR 2.204 and 2.205 that are currently 
cross-referenced in 40 CFR 2.306 are replaced with corresponding 
provisions in the proposed new part 703.

B. Purpose and Applicability

    EPA intends for the proposed requirements to apply broadly to any 
information that is reported to, or otherwise obtained by, the Agency 
under TSCA. 15 U.S.C. 2613(a)(1). This includes, for example, 
information that is submitted pursuant to a requirement of TSCA or its 
implementing regulations (e.g., a TSCA section 5 Premanufacture 
Notification (PMN) or a TSCA section 8(e) notice of substantial risk), 
information that is collected in the course of a TSCA inspection or 
other TSCA enforcement-related activity, and materials that are 
subpoenaed pursuant to TSCA. The proposed rule would also cover 
information which is first obtained by EPA under an authority other 
than TSCA but which meets the following criteria: (1) EPA has authority 
to collect the information under TSCA; and (2) the information is 
either used to satisfy the obligation of a person under TSCA or used by 
EPA in the course of carrying out its responsibilities under TSCA. EPA 
is proposing to interpret the phrase ``that is reported to, or 
otherwise obtained by, the Administrator under TSCA'' to include 
information that meets the two criteria identified above. The term 
``under'' is not defined in TSCA section 14; therefore, EPA is 
proposing to interpret this term as it is commonly used as well as from 
its statutory context. See Kucana v. Holder, 558 U.S. 233, 245 (2010) 
(quoting Ardestani v. INS, 502 U.S. 129, 135 (1991)) (``The word 
`under' `has many dictionary definitions and must draw its meaning from 
its context.' ''). Dictionary definitions can provide some insight into 
how a reasonable or ordinary person would interpret the term. ``Under'' 
is defined as ``subject to the authority, control, guidance, or 
instruction of,'' under, Merriam-Webster Online (2021), and ``subject 
to'' is defined as ``affected by or possibly affected by (something).'' 
Subject to, Merriam-Webster Online (2021). In addition, the broad 
inclusive language used--``reported to, or otherwise obtained by''--
suggests that Congress intended the provision to apply broadly. It 
applies not only to information reported under TSCA but also to 
information obtained under TSCA in manners other than reporting.
    Language added to TSCA by the Lautenberg amendments also supports 
the proposed interpretation that any information EPA has the authority 
to collect under TSCA and is used for TSCA purposes should be 
considered obtained ``under'' TSCA. First, TSCA section 4(h)(3)(A) 
refers to the submission ``under this subchapter'' of voluntary 
information, suggesting information need not be required by a rule or 
order to be submitted ``under'' TSCA. Section 26(j) further provides 
that subject to TSCA section 14, the Administrator shall make available 
to the public ``a list of the studies considered by the Administrator 
in carrying out each such risk evaluation, along with the results of 
those studies.'' 15 U.S.C. 2625(j)(4). Moreover, TSCA section 26(k) 
requires the Administrator to consider ``reasonably available'' 
information when conducting a risk evaluation. This language appears to 
suggest that TSCA section 14 would govern confidentiality 
determinations

[[Page 29081]]

for all studies considered by the Agency under TSCA section 6(b), 
regardless of where the studies originated or how they were obtained.
    However, there may be instances where information covered under 
proposed new part 703 was originally submitted to EPA pursuant to a 
statute with provisions regarding confidentiality, disclosure and 
treatment of information that materially differ from those in TSCA. EPA 
has addressed conflicts between regulatory provisions in 40 CFR 
2.202(d), which states that the ``rule which provides greater or wider 
availability to the public of the information shall govern,'' and more 
specifically in the existing 40 CFR 2.306(b), which provides that under 
the appropriate circumstances TSCA provisions would apply to certain 
information originally submitted to EPA for some non-TSCA purpose. But 
under the Lautenberg amendments to TSCA, EPA will be making use of 
significant amounts of data originating from a variety of sources, 
including existing studies submitted under the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA).
    An example of a scenario in which such a situation may occur is 
where a health and safety study is originally submitted to EPA under 
FIFRA, but is subsequently used for TSCA purposes (e.g., in support of 
a TSCA section 6 risk evaluation) and where the health and safety study 
could have been collected under a TSCA authority (e.g., pursuant to 
TSCA section 8(d)). Under FIFRA section 10(g), the disclosure of such a 
study is limited to protect against disclosure to foreign or 
multinational pesticide producers, but if the study were submitted 
under TSCA, much of the information in the study would not be protected 
from disclosure under TSCA section 14(b)(2).
    The potential for conflict between statutory data protection 
regimes, and the potential for disclosure of information originally 
submitted under the expectation of specified information protection 
requirements, has greatly increased from when the earlier regulations 
were promulgated. EPA recognizes that there are several options for 
dealing with these potential conflicts. As noted above, EPA is 
proposing that in certain circumstances some information obtained under 
authorities other than TSCA are information obtained under TSCA. EPA 
also seeks to ensure that when information is submitted to EPA under a 
statutory provision that provides an assurance of privacy, those 
privacy protections continue to apply even when the information is used 
for a different purpose. Cf Food Marketing Institute v. Argus Leader 
Media, 139 S.Ct. 2356, 2366 (2019) (acknowledging the importance of 
assurances of privacy to determinations regarding the confidentiality 
of information). Thus, EPA is proposing that when there is a conflict 
between statutory data protection regimes, the rules regarding the 
treatment of information in that statute under which the information 
was originally collected should continue to apply to the information, 
regardless of how it is used by the Agency under TSCA. The proposed 
regulations establishing this approach to potential conflicts appear in 
proposed section 703.1. In addition, there are procedures in TSCA 
section 14 that would be appropriate to apply to such data, such as the 
limited disclosure authority, often under confidentiality agreements, 
that is provided by TSCA section 14(d).
    Other alternatives on which EPA requests comment include the 
approach embodied in 40 CFR 2.202(d) that the statute which provides 
for the greatest disclosure of the information governs, or the 
opposite, that the most disclosure-restrictive statute governs. Either 
approach could be implemented by applying the most (or least) 
restrictive statute as a whole or by comparing specific statutory 
provisions with TSCA section 14 and applying the least (or most) 
restrictive provision on a provision-by provision basis. EPA believes 
that the approach presented in proposed section 703.1 strikes an 
appropriate balance and provides greater clarity, as well as being 
consistent with the disclosure requirements applicable when the 
submitter originally provided the information to EPA.
    EPA requests comment broadly on these and any other options for 
addressing, minimizing, or eliminating conflict between provisions 
under different statutes regarding confidentiality, disclosure, and 
treatment of information, including but not limited to alternative 
statutory interpretations, principles that should govern the resolution 
of conflicts, and options for resolving specific conflicts. EPA 
specifically requests comment on whether the proposed approach 
appropriately balances transparency under TSCA while also ensuring 
appropriate protections for information obtained initially under 
another statute consistent with the assurance of privacy implicitly or 
explicitly provided by the government when such information is 
obtained. See Food Marketing Institute v. Argus Leader Media, 139 S.Ct. 
2356, 2366 (2019).
    EPA also specifically seeks public comment on the proposed scope of 
the rulemaking, particularly that information originally obtained 
without the use of a TSCA authority is nevertheless obtained under TSCA 
if the Agency has the authority to collect the information and it was 
used for a TSCA purpose. EPA is also seeking comment on whether EPA 
needs to exercise its TSCA authority or invoke its TSCA authority in 
the original information collection in order for information to be 
covered by TSCA section 14. EPA also seeks public comment on the 
proposed treatment of information that was originally submitted under 
another statute, as well as the alternatives identified. EPA is 
particularly interested in comments on how studies that were originally 
submitted under FIFRA should be treated under the TSCA regulations.
    Finally, EPA is interested in comments on whether and, if so, how 
the term ``TSCA submission'' should be defined in proposed section 
703.3.

C. Requirements for Asserting a Confidentiality Claim

    TSCA section 14(c) governs assertion of confidentiality claims for 
TSCA submissions. This provision requires that persons submitting 
information under TSCA substantiate most confidentiality claims at the 
time of submission. It also includes additional certification and 
generic name requirements. These and related requirements are 
elaborated upon in Unit III.C.
1. Assertion of Confidentiality Claim Upon Submission of Information to 
EPA
    TSCA section 14(c)(1)(a) requires an affected business to assert a 
claim for protection from disclosure concurrent with submission of the 
information. Consistent with this provision, proposed section 703.5 
would require that confidentiality claims be asserted at the time of 
submission. If no such claim is made, the information may be made 
available to the public without prior notice to the person who 
submitted the information. While similar language appears in some of 
the existing regulations that implement TSCA (e.g., 40 CFR 711.30(e)), 
this proposal would clarify that the up-front assertion requirement is 
applicable to all non-exempt TSCA CBI claims, in accordance with TSCA 
section 14(c)(1)(A).
    Proposed section 703.5 would further clarify and reiterate that 
where a TSCA submission identifies a chemical substance listed on the 
confidential portion of the TSCA Inventory but does not assert a 
confidentiality claim for the

[[Page 29082]]

chemical identity as required by TSCA section 14 or in the manner 
required by the applicable rule (see, e.g., 40 CFR 711.30), the 
specific chemical identity would no longer be eligible for confidential 
treatment on the TSCA Inventory. This would not apply where the 
submission does not pertain to manufacture or processing for commercial 
purposes, e.g., research and development.
    The TSCA Inventory is a list of chemical substances manufactured or 
processed for a commercial purpose. A substance may be afforded 
confidential Inventory treatment (e.g., listing by generic name and 
accession number) so long as the fact that anyone manufactures or 
processes that substance for commercial purposes in the United States 
has not been disclosed to the public. By making a non-confidential 
report of having manufactured or processed a particular substance, the 
reporter in effect discloses their activities concerning the substance 
to the public and renders the substance ineligible for continued 
confidential Inventory treatment. EPA would update the TSCA Inventory 
to publicly list the specific chemical name and Chemical Abstracts 
Service Registry Number (CASRN), if available, without further notice 
(to any person who may have made a CBI claim for this substance). 
(Updates to individual submissions that contain a prior claim for what 
appears to be the same information would occur only after that claim is 
withdrawn or as result of a review and final determination in 
accordance with TSCA section 14 denying the claim in that submission.) 
Under some existing rules, once the chemical identity is listed on the 
public portion of the TSCA Inventory, claims can no longer be asserted 
for such information (see, e.g., 40 CFR 711.30(a)(2)(i)). This is also 
intended to clarify that the Agency will not provide notice to 
submitters with previously approved or pending claims for the same 
chemical identity prior to such disclosure on the TSCA Inventory. 40 
CFR 711.30(a)(2)(i)). In addition, other chemical identity CBI claims 
for the substance would likely be denied upon review. However, claims 
for information related to the chemical identity, e.g., the identity of 
the submitter, would not be precluded.
2. Substantiation and Exemptions
    EPA previously published an interpretation concerning the 
requirement to substantiate CBI claims in TSCA section 14(c)(3), see 
(Ref. 6). In that document, EPA stated that the statute requires 
persons asserting CBI claims to substantiate those claims at the time 
the affected business submits the claimed information to EPA. This 
proposed rule, in proposed section 703.5(b)(1), would make EPA's TSCA 
confidentiality regulations consistent with TSCA section 14(c)(3).
    Subsequent to the interpretation that published in the Federal 
Register of January 19, 2017 (Ref. 6), some TSCA rules were updated to 
include a set of required substantiation questions and apply the 
substantiation exemptions in TSCA section 14(c)(2). See, e.g., Chemical 
Data Reporting at 40 CFR 711.30. This proposed rule includes a standard 
set of substantiation questions in proposed sections 703.5(b)(3) and 
(4) that would be applicable to any confidentiality claim in any TSCA 
submission for which substantiation is required and includes additional 
substantiation questions specific to chemical identity claims. However, 
proposed section 703.4(b)(3) would provide that individual TSCA rules 
may modify the questions (by, for example, not requiring answers to 
substantiation questions that are not applicable in a particular TSCA 
submission type).
    The substantiation questions in proposed sections 703.5(b)(3) and 
(4) have been designed to elicit information to allow EPA to determine 
whether the submitter's claim for confidentiality meets the substantive 
review criteria set forth in proposed section 703.7(f). EPA is 
interested in public comment concerning the proposed question set, 
including whether some questions might be consolidated or revised to 
minimize burden while also assuring responses are adequate to support a 
confidentiality determination (i.e., according to the criteria in 
proposed section 703.7(f)). The questions proposed here are similar to 
those included in the 2020 amendments to the Chemical Data Reporting 
(CDR) rule (see 40 CFR part 711) which the Agency believes are adequate 
to support its review of confidentiality claims in those submissions.
a. Patents
    EPA is proposing a question on patents in proposed section 
703.5(b)(3)(iii)(C) and is seeking comment on alternatives to the 
proposed question language, or whether a standalone patent question is 
necessary at all. The Agency requests comment on whether a standalone 
patent question is necessary or if it can be reasonably added to the 
publications question found in proposed section 703.5(b)(3)(iii)(B). In 
the Agency's experience, patents related to information claimed as CBI 
under TSCA rarely if ever disclose information in the same context or 
with the same level of detail as in the related TSCA submission. The 
Agency notes that asking whether information appears in a patent is not 
the same thing as asking whether the information is covered by a 
patent. For the purposes of TSCA confidentiality claims, the Agency is 
interested in both whether the same information claimed to be 
confidential in the TSCA submission appears in a patent and whether it 
is covered by a patent. More specifically, if the exact same 
information appears in both a published patent and in the TSCA 
submission, then the information should not be entitled to confidential 
treatment. Also, if the information is covered (i.e., legally 
protected) by a patent in such a way that no substantial harm to the 
competitive position of the business would result from the release of 
the information, then the information is not subject to confidential 
treatment on that ground as well. If the question of whether TSCA 
information claimed as CBI can both appear in and be covered by a 
patent without destroying the CBI claim can always be answered with a 
yes or no response with no additional explanation, then a standalone 
patent question may not be necessary. The Agency seeks comment from 
submitters explaining why they believe existence of a patent that 
contains and covers the information claimed CBI should not affect the 
ability of the submitter to the claim the same information as CBI under 
TSCA.
    Alternatively, the Agency requests comment on whether the 
standalone patent question used in the 2020 CDR rule (40 CFR 711.30) 
and proposed section 703.5(b)(3)(iii)(C) is adequate, or whether can be 
improved to elicit more pertinent responses from submitters regarding 
the potential public disclosure in a patent of the information claimed 
confidential in the TSCA submission. The existing question is as 
follows: Does any of the information claimed as confidential appear in 
one or more patents or patent applications? If yes, provide the 
associated patent number or patent application number (or numbers) and 
explain why the information should be treated as confidential.
    Particularly, the Agency would like to know how a company would be 
reasonably likely to suffer substantial competitive harm if the 
information is released under TSCA if the company already enjoys legal 
protections against competitors for patent infringement. Further, 
should the patent question elicit substantiation to explain why the 
information claimed to be confidential in the TSCA submission is not 
actually

[[Page 29083]]

revealed in the particular patent? The Agency proposes the following as 
an alternative substantiation question: Has a patent been published for 
the chemical identity you claim confidential? What chemical identity 
information is not revealed by the patent? How is release of that 
specific information likely to cause substantial competitive harm? 
Failure to explain this harm may lead to denial of your confidentiality 
claim.
    The Agency requests comment on whether the proposed alternative 
question is more likely to elicit pertinent responses on the relevance 
of a patent and invites suggestions that may help improve how the 
Agency considers patents in its CBI reviews.
b. Trade Secrets
    EPA has observed that the question concerning trade secrets found 
in several existing TSCA rules, e.g., at 40 CFR 711.30(b)(4), tends to 
elicit answers that are either redundant with the answers to other 
substantiation questions, or otherwise do not tend to include 
information that is useful for the agency to consider whether the 
information meets the specific legal standard for trade secrets. This 
is rooted in confusion about trade secrets and CBI, which are distinct 
but related concepts.
    TSCA section 14(a) invokes FOIA Exemption 4 as a ceiling for 
protecting business information. Exemption 4 protects ``trade secrets 
and commercial or financial information obtained from a person and 
privileged or confidential.'' 5 U.S.C. 552(b)(4). Trade secrecy has 
long been held as grounds for Exemption 4 protection distinct from that 
for ``commercial or financial information obtained from a person and 
privileged or confidential.'' See, e.g., Public Citizen Health Research 
Group v. FDA, 704 F.2d 1280, 1286 (D.C. Cir. 1983).
    A trade secret has been defined by the D.C. Circuit as ``a secret, 
commercially valuable plan, formula, process, or device that is used 
for the making, preparing, compounding, or processing of trade 
commodities and that can be said to be the end product of either 
innovation or substantial effort.'' Public Citizen at 1288. This 
definition also incorporates a requirement that there be a ``direct 
relationship'' between the trade secret and the productive process.
    CBI is defined by 5 U.S.C. 552(b)(4) as information that is (a) 
commercial or financial, (b) obtained from a person, and (c) privileged 
or confidential. The U.S. Supreme Court has addressed the meaning of 
the word ``confidential'' in 5 U.S.C. 552(b)(4) stating that 
``confidential'' must be given its ``ordinary'' meaning, which is 
information that is ``private'' or ``secret.'' Food Marketing Institute 
v. Argus Leader Media, 139 S. Ct. 2356, 2363 (2019). The Court held 
that at least where commercial or financial information is both 
customarily and actually treated as private by its owner and provided 
to the government under an assurance of privacy, the information is 
``confidential'' within the meaning of FOIA Exemption 4. Food Marketing 
at 2366. In addition, TSCA section 14 requires the submitter to 
demonstrate that it has a reasonable basis to conclude that disclosure 
of the information is likely to cause substantial harm to the 
competitive position of the business.
    While the trade secret standard and CBI standard could 
theoretically provide two avenues to protect information from 
disclosure, EPA is not aware of any situation where information 
submitted under TSCA was determined to be entitled to trade secret 
protection but not CBI protection. EPA does not believe that asking a 
specific trade secret question for TSCA confidentiality substantiations 
will generate useful information because of the considerable overlap 
between the two standards. EPA seeks comment on whether the trade 
secret question still has value in the context of TSCA confidentiality 
claims.
c. Specificity of Competitive Harm
    In order to properly evaluate the various CBI claims in a single 
submission, EPA needs a separate explanation from the submitter for 
each type of information claimed as confidential to explain why 
disclosure of that information would be likely to cause substantial 
competitive harm. To that end, EPA proposes two versions of the 
substantiation question concerning substantial competitive harm in this 
rulemaking. The first version of the question comes directly from the 
CDR rule, which states: ``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.'' 40 CFR 711.30(b).
    The second version for consideration is in proposed section 
703.5(b)(3)(i): Please specifically explain what harm to the 
competitive position of your business would be likely to result from 
the release of the information claimed as confidential. How would that 
harm be substantial? Why is the substantial harm to your competitive 
position likely (i.e., probable) to be caused by release of the 
information rather than just possible? If you claimed multiple types of 
information to be confidential (e.g., site information, exposure 
information, environmental release information, etc.), explain how 
disclosure of each type of information would be likely to cause 
substantial harm to the competitive position of your business.
    The version of the question in proposed section 703.5(b)(3)(i) may 
enable EPA to better determine whether disclosure of the information is 
likely to cause substantial harm to the competitive position of the 
submitter. For purposes of this question, the term ``substantial'' 
means ``of considerable importance.'' Oxford English Dictionary (2021). 
``Likely'' means ``probable.'' Oxford English Dictionary (2021). The 
last portion of the question is intended to help submitters explain how 
each type of information claimed confidential could harm the business 
if released. For instance, the harm to the business that could result 
from release of a confidential chemical identity may be different from 
the harm that could result from release of information concerning the 
number of workers exposed to the chemical during processing.
    EPA requests comment from submitters and the public on which of the 
two proposed versions of the question would be most likely to elicit 
information from submitters that will best allow EPA to determine that 
the submitter has demonstrated a reasonable basis to conclude that 
disclosure of the information is likely to cause substantial harm to 
the competitive position of its business. EPA is also seeking comment 
on how ``substantial'' and ``likelihood'' should be defined.
d. Exemptions
    The proposed section 703.5(b)(5) addresses the TSCA section 
14(c)(2) exemptions from the substantiation requirement. This proposed 
provision includes criteria for the exemption in TSCA section 
14(c)(2)(G) pertaining to substances that have not been offered for 
commercial distribution. The other proposed exemptions include:
     Specific information describing the processes used to 
manufacture or process a chemical (e.g., information reported under 40 
CFR 720.45(g)(2));
     Marketing and sales information (note that submitting 
company identifiers are not generally themselves

[[Page 29084]]

considered marketing and sales information);
     Information identifying a supplier or customer (such as 
the identities of some joint submitters reporting information under 40 
CFR720.40(e) or 711.15);
     Details on mixture composition and percentage (such as 
might be included in a TSCA section 8(e) notice of substantial risk 
that concerns a mixture);
     Specific chemical substance use information (such as is 
required to be reported under 40 CFR 720.45(f) and 725.155(g)); and
     Specific production or import volumes (such as are 
required to be reported under 40 CFR 711.15 and 720.45(e).
    EPA expects to update the reporting forms and applications for most 
TSCA submissions to prompt the submitter for substantiation where 
required, but not to prompt the submitter for types of data the Agency 
has concluded are always covered by a substantiation exemption.
3. Public Copies of Submissions
    In proposed section 703.5(c), EPA proposes to require public copies 
of submissions that include confidentiality claims. The proposed rule 
would not require preparation of a separate public copy where the 
reporting form or electronic reporting application contains a specific 
CBI designation identifying specifically what is claimed as CBI. 
However, where the submission is made without the use of such a TSCA 
reporting form (e.g., subpoena responses), or includes attachments or 
other ``non-fielded'' data, the submitter would be required to produce 
and submit a public (sanitized) copy of the submission and/or 
attachments. Some existing TSCA rules already include such a 
requirement. See, e.g., 40 CFR 720.40(d)(2) and 716.55(b). This 
proposed rule would consolidate existing requirements in proposed new 
part 703 and extend them generally.
    The proposed provision would also provide that the sanitized 
version would have to redact only that information that is claimed as 
confidential. Any information not included in the sanitized version, or 
redacted from the sanitized version, must be subject to a 
confidentiality claim and as such must be substantiated as described in 
this unit. It further states that a public copy that redacts all or 
substantially all of the original submission would most likely not meet 
the requirements of the rule because it is unlikely that all of the 
information in a form or attachment can be appropriately claimed CBI. 
Additionally, any information not included in or redacted from a public 
copy is subject to the supporting statement in TSCA section 14(c)(1)(B) 
and the certification requirement in TSCA section 14(c)(5). False 
statements may give rise to criminal liability under 18 U.S.C. 1001.
4. Supporting Statement and Certification
    TSCA section 14(c)(1)(B) requires that each claim of 
confidentiality be accompanied by a standard supporting statement 
regarding the eligibility of the information for confidential 
treatment. TSCA section 14(c)(5) also requires a certification that the 
TSCA section 14(c)(1)(B) statement and information required to 
substantiate the claim under TSCA section 14(c)(3) are true and 
correct. (See explanation in Unit III.A.2. of the preamble to the CDR 
rule (Ref. 7)). This supporting statement and certification language 
has already been incorporated in most TSCA reporting forms (example 
available at https://www.epa.gov/tsca-cbi/making-cbi-claims-tsca-submissions#howto). To the extent that the submission is not being made 
on such a reporting form (e.g., a subpoena response), proposed section 
703.5(a) provides language that may be included in a cover letter or 
other attachment to a submission.
5. Generic Names
    TSCA section 14(c)(1)(C) requires the submission of a generic name 
any time a specific chemical identity is claimed as confidential. This 
provision further requires that the generic name be ``structurally 
descriptive'' and that it ``describe the chemical structure [. . .] as 
specifically as practicable'' while also protecting the features of the 
chemical substance that are claimed confidential or where disclosure 
would likely cause substantial harm. 15 U.S.C. 2613(c)(1)(C)(ii). The 
generic name must also be consistent with the generic name guidance 
developed in accordance with TSCA section 14(c)(4)(A), 15 U.S.C. 
2613(c)(1)(C)(i). See Refs. 8, 9 and 10. The generic name guidance 
document provides information to assist companies in creating 
structurally descriptive generic names for chemical substances whose 
specific chemical identities are claimed confidential, for the purposes 
of protecting the specific chemical identities from disclosure while 
describing the chemical substance as specifically as practicable, and 
for listing substances on the TSCA Chemical Substance Inventory. The 
proposed rule acknowledges that the TSCA Inventory already includes 
generic names for confidential substances, and that in most cases, such 
generic names are expected to be acceptable for the purposes of 
compliance with TSCA section 14(c)(1)(C) (possible exceptions may 
include generic names for some substances added to the TSCA Inventory 
prior to June 22, 2016, which would be addressed under proposed section 
703.5(d)(2)).
    For substances that are not on the TSCA Inventory (e.g., new 
chemical submissions under TSCA sections 5 or 8(e) submissions 
concerning pre-market chemical substances), the proposed rule includes 
a few basic criteria, drawn mainly from the TSCA section 14(c)(4)(A) 
guidance (e.g., the generic name should mask only the confidential 
portions of the specific chemical name, generally only one structural 
element of a specific chemical name may be masked to protect a 
confidential chemical identity), and would require that where the 
submitter believes those criteria are in some way inappropriate or 
inapplicable to a particular substance or generic name, the submission 
must also include an explanation for why more extensive masking of the 
specific chemical identity is necessary in the particular case.
    In proposed section 703.5(d)(3), EPA is also proposing that where a 
generic name submitted for a substance that is not on the TSCA 
Inventory is acceptable for the purposes of meeting the requirements of 
TSCA section 14(c)(1)(C), the generic name might nonetheless be later 
subject to additional review and potential change when commercial 
manufacture of the substance is commenced (e.g., when a Notice of 
Commencement (NOC) is submitted). Further procedures and requirements 
for review and acceptance of generic names submitted with an NOC are 
elaborated in proposed revisions to 40 CFR 720.102 and 725.190, As 
discussed in Unit II.E.5.
    Finally, in proposed section 703.5(d)(4), EPA is proposing to 
provide an opportunity to revise proposed generic names that EPA 
concludes are not in compliance with 15 U.S.C. 2613(c)(1)(C). EPA would 
provide an electronic notice of the deficiency to the submitting 
company, who would then be afforded ten days to propose a revised 
generic name. If the submitter does not submit a compliant generic 
name, EPA would reject the underlying submission and may ultimately 
deny the CBI claim. (See discussion in Unit III.C.4. and proposed 
section 703.5(e) on deficient submissions.)
6. Deficient Submissions
    In proposed section 703.5(e), EPA is proposing to specify that 
confidentiality

[[Page 29085]]

claims, identified for review pursuant to proposed section 703.7(a), 
that are missing the certification, substantiation, or generic name 
(where applicable) required by TSCA section 14(c) will be considered 
deficient. Submissions that are missing a public copy or where the 
public copy does not meet the requirements of proposed section 
703.5(b)(6) would also be considered deficient-EPA has observed many 
instances where the attachments to TSCA submissions appear over-
redacted (e.g., public copies of health and safety studies or the 
Safety Data Sheets (SDSs) that are often provided with TSCA section 5 
PMN submissions might be entirely or largely blank). This level of 
redaction is rarely if ever consistent with the limitations that TSCA 
section 14(b) places on CBI protections for health and safety 
information. Submissions that include a generic name that does not meet 
the requirements of proposed section 703.5(d) or rely on inappropriate 
substantiation exemption assertions would also be considered deficient.
    EPA anticipates that electronic reporting requirements, coupled 
with modifications to new and existing reporting forms to incorporate 
the certification statements and prompt for substantiation and generic 
names, will eliminate most such deficiencies. However, to the extent 
TSCA submissions are occasionally still made on paper or are not made 
using a TSCA form for which entries can be automatically validated 
(e.g., unformatted information in attachments to TSCA forms, such as 
health and safety study reports or SDSs), such deficiencies may still 
occur. EPA is proposing that when such deficiencies are identified, EPA 
would initially place a hold on the submission.
    In such an instance, EPA would provide notice of the deficiency to 
the submitter and provide them with a ten (10) business day opportunity 
to fix the deficiency. Meanwhile, any applicable review periods for the 
underlying submission and for the confidentiality claim would be 
suspended while the hold is in place. For example, if EPA held a PMN 
for an inadequate public copy, both the CBI review period and the 90-
day review period for the PMN would be suspended until either (1) the 
deficiency in the CBI claim is remedied, or (2) ten (10) business days 
pass without the deficiency being remedied.
    If the deficiency is not remedied within ten (10) business days of 
EPA providing the notice of deficiency, EPA will resume the review of 
the submission and will likely deny the CBI claim(s).
    EPA is interested in public comment on this approach to claim 
deficiencies, and on alternative approaches, such as strictly 
interpreting the requirements of TSCA section 14(c) as necessary to 
making a valid confidentiality claim (i.e., claims that don't meet the 
requirements of TSCA section 14(c) would not be recognized, and could 
thereby be released to the public without prior notice to the 
submitter). Additionally, EPA is not proposing a time window in which 
the Agency may identify deficiencies, which potentially leaves open the 
possibility that a deficiency is identified, for example, on day 45 of 
the review period for the underlying submission. EPA is particularly 
interested in public comment on whether a time period for identifying 
deficiencies, e.g., between 10 to 15 business days from the date of 
submission, would be appropriate.
7. Electronic Reporting
    Most TSCA submissions must now be made electronically, using 
various reporting tools built into CISS (Chemical Information 
Submission System, EPA's web-based reporting tool for preparing and 
submitting TSCA submissions) and submitted via EPA's CDX system 
(Central Data Exchange, EPA's centralized electronic document reporting 
portal). The proposed section 703.5(f) would fill most of the current 
gaps in electronic reporting requirements by requiring that nearly all 
TSCA confidentiality claims be asserted electronically. For example, 
while current TSCA section 8(e) notices of substantial risk may be made 
either on paper or via an optional electronic reporting form, EPA is 
proposing that all TSCA section 8(e) notices that include a 
confidentiality claim would be required to be submitted electronically, 
using an EPA-provided reporting tool. Similarly, electronic reporting 
applications would be developed or updated for TSCA section 12(b) 
notices of export and TSCA section 5 polymer exemption notifications. 
Means of providing information via CDX relating to TSCA section 6 
prioritization, risk evaluation, and risk management have already been 
made available. These new and updated reporting applications would be 
available by the time the new electronic reporting provisions become 
effective. This proposal would expand the electronic reporting 
requirement to all TSCA section 12(b) notices of export and TSCA 
section 5 polymer exemption notifications (whether or not they include 
confidentiality claims), thereby closing most remaining gaps in 
electronic reporting requirements under TSCA. A discussion on the 
benefits of electronic reporting under TSCA relevant to the expansion 
described in this proposed rule was provided in a previous document 
(Ref. 1). Some exceptions to the general requirement to report CBI-
containing materials electronically will remain, such as for materials 
that EPA has subpoenaed or requested or collected in the course of a 
TSCA inspection, which may be collected in person, and/or in a format 
or volume that makes electronic submission impractical.
    Closing these gaps in electronic reporting is intended to reduce 
the likelihood of submitter error when asserting a confidentiality 
claim, facilitate EPA's ability to review confidentiality claims in a 
timely manner, reduce resources required to process, handle, and store 
TSCA submissions, reduce the opportunity for errors related to the 
handling of CBI, facilitate public access to information not claimed as 
CBI, and enable or enhance EPA and TSCA submitters' ability to promptly 
communicate about the status of confidentiality claims in the 
submission in the future. EPA will enhance its current practice of 
assigning a document or ``case'' number to each TSCA submission (e.g., 
P-20-0XXX or 8EHQ-2020-0XXXX) by assigning and making that submission 
identifier available to the submitter within the submitter's CDX 
account.
    As stated above, EPA is proposing to require any information or 
materials not obtained under TSCA section 11 to be submitted through 
CDX if they contain a TSCA CBI claim. The Agency is requesting public 
comment broadly on this approach, and on whether there are scenarios 
the Agency should consider where a person providing TSCA CBI to EPA via 
an irregular means (e.g., a letter) would not be able to or would face 
substantial difficulties in using CDX to submit information claimed 
CBI.
8. Requirement To Report Health and Safety Information Using Harmonized 
Templates
    In proposed section 703.5(g), EPA is proposing a requirement to 
provide health and safety studies and information from health and 
safety studies in a templated format, using Organisation for Economic 
Co-operation and Development (OECD) Harmonized Templates, where an 
applicable template is available. See https://www.oecd.org/ehs/templates/harmonised-templates.htm. EPA is interested in comment on 
this proposed requirement. Many TSCA submitters may be familiar with 
and already have created templated versions of health and safety study 
reports they may be

[[Page 29086]]

required to submit under TSCA, owing to reporting requirements in other 
countries. For these submitters, the burden associated with this 
requirement to submit templated data is expected to be minimal. EPA 
anticipates that data that has been put into one of these standardized 
templates will be more readily used and shared within the Agency, and 
(where permitted by confidentiality restrictions and other agreements) 
across jurisdictions. In addition, CBI clams may be more clearly 
indicated if asserted via a templated format (e.g., CBI claims could be 
indicated by checking a box for each discrete data element, rather than 
by redacting sections of text piecemeal from a study report line by 
line). It should be noted, however, that the proposed requirement to 
provide data in a templated format does not supersede existing 
regulatory requirements to also submit a full study report, such as the 
present requirement for TSCA section 4 test reports.
    EPA is soliciting public comment on the proposed requirement that 
information obtained from a study, in addition to whole study 
submissions, be provided in templated form to the Agency. EPA is also 
interested in public comments on the requirement that submitters 
identify the ``appropriate'' OECD template for a particular submission.
9. Maintenance of Company Contact Information and Communications 
Concerning Claims
    From time to time, EPA needs to contact a company about CBI claims 
made in a TSCA submission. These contacts may be made relatively soon 
after submission, in order to clarify something about a claim or 
provide an opportunity to correct a deficiency with the claim (see 
proposed section 703.5(e)), or they may be required notifications made 
months or years later, such as a notice concerning a denied 
confidentiality claim, or a notice concerning a pending confidentiality 
review under TSCA section 14(f). In the future, EPA will also need to 
contact or notify companies about expiring confidentiality claims, 
pursuant to TSCA section 14(e). For all of these reasons, it is 
important for EPA to have current contact information for the submitter 
of each TSCA submission and an efficient means for satisfying the 
notice requirements under the statute. EPA is proposing to require 
companies to maintain current contact information for all individuals 
associated with a submission (which reinforces and complements existing 
CDX terms and conditions concerning maintenance of CDX accounts, 
particularly the requirement to notify EPA when individual account 
access is no longer needed so that the account can be deactivated; see 
https://cdx.epa.gov/Terms), enhance the means by which companies update 
contact information, and require the submission of notices of transfer 
of ownership via CDX.
    In light of the significant resources and document tracking 
concerns related to continuing to largely rely on paper correspondence 
for such communication and notifications, the rulemaking proposes that 
most such correspondence would be electronic, via CDX. See proposed 
section 703.5(h). ``Two-way'' communication via CDX provides a secure 
means for EPA and companies to correspond about a TSCA submission or 
confidentiality claims. EPA can more readily assure that a 
communication is available to a company or specific submitter by using 
CDX to communicate, rather than certified mail or a courier. In CDX, 
EPA is able to verify that a particular communication is available to 
the submitter of a particular submission and is able to track the date 
the communication was sent. EPA believes that these facts satisfy the 
requirement in TSCA section 14(g)(2)(A) that notification, including 
for the denial of a confidentiality claim, be sent by means that 
``allows verification of the fact and date of receipt.'' This would be 
the case even if EPA does not receive a ``read receipt'' or cannot 
otherwise verify that the submitter opened the electronic notice, much 
as EPA cannot verify whether or when a recipient of certified mail 
opens the envelope and reads the contents.
    The proposed rule describes how EPA expects to furnish the required 
notices concerning expiration of confidentiality claims under TSCA 
section 14(e). The first expirations will occur in 2026, for claims 
that were asserted in 2016 and that were not exempt from substantiation 
and review according to TSCA sections 14(c)(2) and 14(g). As proposed, 
EPA would periodically publish a list of TSCA case numbers that are 
approaching claim expiration on the EPA website, or other appropriate 
platform. In addition, EPA intends to send individual notices of 
upcoming claim expiration and other individual notices concerning CBI 
claims to the company via CDX.
    The proposed rule includes similar notice and communication 
provisions for when review of claims is initiated under TSCA section 
14(f) (e.g., in response to a FOIA request for information that has 
been claimed as confidential). EPA would provide any necessary notice 
of review and/or opportunity to substantiate or resubstantiate to the 
Authorized Official or Technical Contact listed on the most recent 
version of the submission (or as listed in a more recent notice of 
transfer of ownership relating to that submission), along with 
instructions for response. Alternatively, if the submission with the 
relevant CBI claim is not associated with a CDX account, EPA would send 
the notice via CDX to the company contact provided in the most recent 
TSCA submission made by that company.
    For TSCA submissions that were not originally made via CDX, EPA is 
proposing to send the notice by certified mail or courier to the 
address provided in the most recent TSCA submission from that company, 
or via other means that allows verification of the fact and date of 
receipt. For example, EPA is also considering further development of 
two-way CDX communication to permit EPA to also send these notices, 
likely using the contact information in the most recent CDX submission 
from the same company.
10. Withdrawing Claims
    TSCA confidentiality claims may be voluntarily withdrawn by the 
submitter at any time. See 15 U.S.C. 2613(e)(1)(A)(i) and (B)(ii)(I). 
Proposed section 703.5(i) includes instructions for voluntarily 
withdrawing confidentiality claims prior to automatic expiration or 
denial. The preferred approach is for the company to amend the 
submission electronically, via CDX, to withdraw the claims (i.e., 
``uncheck'' the CBI boxes or unredact the submission and resubmit it). 
When this is not possible (for example, when the submission was not 
originally submitted via CDX, or because the company does not have 
access to the electronic submission), claims may be withdrawn by CDX 
submission as well, using a new correspondence tool that enables 
efficient linking of the withdrawal letter with the related submission, 
and permits EPA to communicate with the company about the withdrawal 
(e.g., if clarification is needed).
11. Amending a Public Copy Following Claim Denial or Expiration
    Following the denial or expiration of a confidentiality claim, the 
public copy of the submission must be revised to provide public access 
to the newly non-CBI information. For some electronic submissions this 
may be a more or less straightforward process of un-checking some boxes 
and generating a new public copy of the submission, but for other TSCA 
submissions, the denied or

[[Page 29087]]

expired claims may be intermingled with still-valid or approved claims, 
or the claims may have been indicated by numerous redactions throughout 
a voluminous text. The proposed rule (see proposed section 703.5(j)) 
would encourage companies to prepare this updated public copy 
themselves. EPA believes that submitters are in the best position to 
assert and indicate their remaining claims accurately. However, in the 
case that the submitter is unavailable or otherwise unable to update 
the public copy, the proposed rule makes clear that EPA will undertake 
this function, as needed.
    EPA invites comment on the option of requiring TSCA submitters to 
update their original submission to reflect CBI claims that have been 
withdrawn or denied.

D. EPA Review of Confidentiality Claims

1. Representative Subset
    TSCA section 14(g)(1)(A) requires that EPA approve or deny 
confidentiality claims, except for claims exempt from review under TSCA 
section 14(c)(2). TSCA section 14(g)(1)(C) further specifies that EPA 
review all confidentiality claims for chemical identity (except those 
exempt under TSCA section 14(c)(2)(G)) and a ``representative subset'' 
comprising at least 25% of all other claims, with the exception (as 
provided in TSCA section 14(g)(1)(A)) of information exempted from 
substantiation under TSCA section 14(c)(2).
    Proposed section 703.7 would codify EPA's current practice of 
reviewing all claims (except those exempt from substantiation 
requirements under TSCA section 14(c)(2)) in every fourth submission 
received via CDX that contains CBI claims besides those pertaining to 
chemical identity.
    Consistent with current practice, submissions with CBI claims not 
submitted through CDX would be excluded from the representative subset. 
As explained above, all submissions other than those submitted pursuant 
to TSCA section 11 will be required to be submitted through CDX (see 
proposed section 703.5(f)), so the Agency believes that only a small 
number of infrequent TSCA submissions would not be included in the 
total number of claims received for purposes of determining the 
representative subset. Moreover, these materials are not representative 
of TSCA submissions because they are collected irregularly, from widely 
spread geographic locations, may be voluminous, provided in multiple 
batches, be of assorted media type (photos, large maps, etc.) or exist 
only on paper or other physical media at the time of collection. EPA is 
also proposing that amendments to submissions would not be counted as 
new submissions for purposes of selecting the representative subset--
rather, the confidentiality claim review will include amendments 
available at the time of review. EPA is interested in public comment 
concerning its selection of the representative subset, including 
possible alternative representative selection methods.
    EPA is proposing that two additional types of submissions not be 
included in the representative subset as they are not representative of 
TSCA submissions as a whole. These include: (1) Bona fide inquiries 
under 40 CFR 720.25, and 721.11 and (2) TSCA section 5 prenotice 
communications (correspondence submitted prior to a prospective TSCA 
section 5 submission asking questions or requesting a meeting to 
discuss whether and how a prospective TSCA submission should be made). 
These document types are not representative of TSCA submissions as a 
whole. These submission types help submitters ascertain whether a TSCA 
submission is required in a particular situation and/or what type or 
format should be used to make a particular submission. Moreover, in 
each case in which EPA confirms that a specific TSCA submission is 
required, these pre-notice or bona fide submissions would be followed 
by the corresponding TSCA submission, which itself would be subject to 
selection as part of the representative subset (e.g., a PMN or 
Significant New Use Notice). Conversely, where no TSCA submission is 
deemed necessary, the information in these documents does not relate to 
EPA's regulation of chemical substances under TSCA.
    EPA is interested in public comment concerning the universe of 
claims that contribute to the representative subset and its 
identification of, and exclusions from, the representative subset, 
including possible alternatives.
2. EPA Review of Claims
a. Procedures
    EPA is proposing to revise EPA's procedures for reviewing 
confidentiality claims. As noted in previous EPA statements (e.g., Ref. 
6), EPA reviews confidentiality claims in accordance with the 
requirements in TSCA section 14 and has relied to date on the review 
procedures set out in 40 CFR part 2 for all TSCA CBI reviews. However, 
the review procedures described in 40 CFR part 2 (including TSCA-
specific provisions at section 2.306), which were promulgated prior to 
the Lautenberg amendments, do not fully accommodate or account for the 
requirements in TSCA section 14, particularly the demands of the TSCA 
section 14(g)(1) mandatory review program. Rather than extensively 
update the EPA review procedures for TSCA CBI in 40 CFR part 2 to 
reflect the amendments to TSCA section 14, this rulemaking proposes to 
consolidate most of them in the proposed new part 703, consistent with 
the broader effort to centralize regulations on TSCA CBI.
    In many respects, the procedures and substantive review criteria in 
proposed new part 703 mirror those in 40 CFR part 2 but include 
adaptations to reflect the requirements of TSCA section 14, and to 
facilitate the high volume, time-limited review process required to 
meet the requirements of TSCA sections 14(e) and 14(g). For example, 
the substantive criteria in 40 CFR 2.208, as referenced and modified by 
40 CFR 2.306(g), would be retained, but would be somewhat modified to 
align with the substantial competitive harm language in TSCA section 
14. (The other criteria include that the CBI claim has not expired, 
been waived, or withdrawn; that the business protects the 
confidentiality of the information; and that no statute prohibits 
confidential protection.)
    The criteria would also be revised to clarify that whether a 
substance may be readily reverse engineered is among the factors EPA 
considers as part of the criterion on whether the CBI-claimed 
information is legitimately and reasonably obtainable without the 
business's consent. Alternatively, the Agency could consider whether a 
substance may be readily reverse engineered as a stand-alone criterion. 
The Agency requests comment on how this reverse engineering component 
should be incorporated into the Agency's substantive review criteria in 
proposed section 703.7(f), either as a stand-alone review criterion or 
as part of the existing criterion. The substantive review criteria in 
proposed section 703.7(f) will establish the Agency's standard of 
review for all TSCA CBI claims. For each claim to be approved, 
submitters' substantiations would be required to adequately address all 
of the criteria set forth in proposed section 703.7(f). Accordingly, 
the Agency would then be able to deny TSCA CBI claims for failure to 
address any one of the proposed criteria in the substantiation.
    The requirement in 40 CFR 2.306(e)(1) that EPA's Office of General 
Counsel (OGC) make most final confidentiality determinations would no 
longer be required by regulation under the proposed new part 703; 
rather, final determinations may be made by OGC or

[[Page 29088]]

other EPA offices (e.g., the EPA Office of Pollution Prevention and 
Toxics), as designated by the General Counsel. Regardless of which 
office within EPA issues a given final determination, EPA expects to 
continue to publish final CBI determinations on its website.
    EPA also proposes, in proposed section 703.7(g), to add a means to 
request reconsideration by OGC of determinations denying confidential 
treatment. Reconsideration would be available during the 30-day notice 
and appeal period prior to disclosure of the information. This 
mechanism is intended to permit parties to identify any EPA errors in 
the determination prior to the point that the information is disclosed, 
and without immediately proceeding to judicial review of the decision. 
If a request for reconsideration is timely received, EPA will suspend 
the 30-day notice period described in proposed section 703.7(e) while 
OGC reconsiders the Agency's determination. OGC will review the 
submission de novo and will only consider the submission record as it 
existed for the final determination. EPA requests comment on this 
reconsideration approach and the suspension of the 30-day notice 
period.
    The proposed rule sets forth review procedures to apply to CBI 
reviews initiated under TSCA section 14(g)(1) (including reviewing 
requests for extension under TSCA section 14(e)) as well as some 
additional procedures to implement CBI reviews initiated under TSCA 
section 14(f). In proposed section 703.7(b)(2), EPA proposes to permit 
submitters requesting extension of confidentiality protections under 
TSCA section 14(e) to either submit new substantiation or rely on 
substantiation that was provided with the initial submission, 
certifying that the substantiation remains true and correct.
    In proposed section 703.8, EPA proposes similar procedures for 
reviews initiated under TSCA section 14(f) as for those under TSCA 
section 14(g), though the notice and resubstantiation provisions 
necessarily vary to reflect the fact that the review of different 
claims may be triggered by TSCA section 14(f) versus TSCA section 
14(g). The proposed rule also clarifies that EPA is not required to 
review claims as designated in TSCA section 14(f)(1) (claims concerning 
active or TSCA section 6(b) high-priority substances or where 
disclosure would assist EPA in conducting a risk evaluation under TSCA 
section 6); rather, reviews of such claims are discretionary.
    The proposed rule also elaborates on the timing and scope of review 
in proposed section 703.7(c). For the purposes of TSCA section 14(g), 
the proposed rule specifies that the 90-day review period begins on the 
day EPA accepts a new TSCA submission that includes confidentiality 
claims (TSCA submissions under TSCA section 5 must clear a brief ``pre-
screen'' review for basic completeness to ensure consistency with 
requirements in 40 CFR part 720, which is usually complete within a few 
days of submission; following that review, the submission is considered 
``accepted''), and that amendments to non-chemical identity information 
in the submission will be considered in the confidentiality review for 
that submission up to 60 days after the original submission date. (New 
confidentiality claims concerning chemical identity would be reviewed 
within 90 days of EPA accepting the submission or amendment including 
the new chemical identity claim.) The date that the submission is 
considered ``accepted'' will be used to calculate the 10-year sunset 
period for purposes of TSCA section 14(e). ``Accepted'' is defined in 
the proposed section 703.3.
    EPA notes that some submission types are often amended one or more 
times after submission (e.g., new chemical-related submissions under 
TSCA section 5) as new information is developed, or as requested by 
EPA. In order to meet the 90-day statutory review deadline, EPA 
believes it is important that submissions be complete, at least 
procedurally, prior to starting review, and notes that there is a point 
in the 90-day period past which significant amendments to the 
submission and related claims would be difficult or impossible to 
consider while still meeting the statutory review deadline.
    EPA has considered some alternatives in developing this proposed 
rule, including either resetting the 90-day clock every time an 
amendment is received, or not commencing confidentiality claim review 
at all until some period of time after initial submission, to allow for 
a majority of amendments to be made prior to beginning the 
confidentiality review. In the first case, EPA identified that 
resetting the 90-day clock with each amendment would likely require a 
lot of duplicative effort. EPA also anticipates that either of these 
options would often delay confidentiality determinations considerably, 
especially for new chemical submissions, in which public interest has 
been heightened in recent years. EPA invites public comment on the 
proposed approach described in proposed section 703.7(c), as well as 
these and other alternatives.
b. Substantial Competitive Harm
    In the preamble of the 2020 final rule on CDR (Ref. 7), EPA noted 
that the Agency did not view the Supreme Court's decision in Food 
Marketing Institute v. Argus Leader Media, 139 S. Ct. 2356, 2363 (2019) 
as necessitating the Agency to remove the ``substantial competitive 
harm'' substantiation question for TSCA CBI claims. See also Ref. 11. 
Congress amended TSCA section 14 in 2016 to, among other things, 
specifically require any person asserting a CBI claim under TSCA to 
include a certified statement that the person has ``a reasonable basis 
to conclude that disclosure of the information is likely to cause 
substantial harm to the competitive position of the person.'' TSCA 
section 14(c)(1)(B)(iii) and (c)(5); see also TSCA section 
14(c)(1)(C)(ii)(II) (referencing substantial competitive harm). For 
each claim, the Agency's review will determine whether the business has 
made a satisfactory showing that it has a reasonable basis to conclude 
that disclosure of the information is likely to cause substantial harm 
to the competitive position of the business.
    The proposed rule clarifies that the Agency requires the 
certification statement on substantial competitive harm and considers 
substantial competitive harm as part of its substantive review criteria 
for TSCA CBI claims.
c. Information From Health and Safety Studies
    The proposed rule also elaborates on the limitations on 
confidentiality protections for health and safety information described 
in TSCA section 14(b). TSCA section 14(b)(2), which denies 
confidentiality protection to health and safety studies and information 
from health and safety studies, excludes from its coverage certain 
categories of information in health and safety studies, such as 
formulas. In addition, existing regulations allow withholding of 
specified information beyond that provided in TSCA section 14(b)(2). 
See, e.g., 40 CFR 720.90(3) (allowing withholding of ``[i]nformation 
which is not in any way related to the effects of a substance on human 
health or the environment, such as the name of the submitting company, 
cost or other financial data, product development or marketing plans, 
and advertising plans''). However, the applicable regulations are not 
uniform in this respect; nor has the statutory basis for these 
provisions (which itself has changed under the Lautenberg

[[Page 29089]]

amendments) been previously enunciated by EPA. The Agency is proposing 
here to systematize these provisions, generally allowing CBI claims for 
very limited categories of information contained within a health and 
safety study.
    While such ancillary information may be contained in a study 
document submitted under TSCA, EPA does not consider such information 
to be part of a ``health and safety study'' as defined in TSCA section 
3(8). That definition states that the term `health and safety study' 
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 chapter. This definition does not seek to provide an 
exclusive list of what is or is not ``included'' in the health and 
safety study but instead clarifies that all ``underlying'' information 
must be considered part of the study. The term ``underlying'' is an 
adjective ``used to describe something on which something else is 
based.'' Cambridge Dictionary (Online). A study report may contain 
information beyond that which is the basis for the study. Information 
such as the names of lab technicians neither form the basis for the 
study nor are relevant to the study results.
    Additionally, TSCA section 14(b)(1) provides that information that 
is protected from disclosure under this section, and which is mixed 
with information that is not protected from disclosure under this 
section, does not lose its protection from disclosure notwithstanding 
that it is mixed with information that is not protected from 
disclosure. TSCA section 14(b)(1) is consistent with the interpretation 
that a study report can contain information not included within the 
definition of a ``health and safety study'' under TSCA section 3(8) and 
adopting such an interpretation gives effect to TSCA section 14(b)(1).
    EPA is therefore proposing a definition of ``health and safety 
study'' (for purposes of this proposed rule) in proposed section 703.3 
that specifies types of information that are not within the scope of 
TSCA section 3(8):
     Name of the submitting company;
     Name of the laboratory;
     Internal product codes;
     Names of laboratory personnel;
     Names and other private information included in study data 
or reports;
     Cost or other financial data; and
     Product development, advertising, or marketing plans.
    The Agency is requesting comment on the underlying interpretation 
and this list.
    This proposed rule would clarify these existing provisions and make 
them uniform for all TSCA submissions. EPA invites comment on the 
proposed examples of information that might be in a study, but 
nonetheless permissible to withhold as confidential, should the 
information otherwise meet the confidentiality criteria in TSCA section 
14.

E. Related or Corresponding Revisions to Other TSCA Rules

    In addition to proposing a new confidentiality claim section of the 
TSCA rules, the proposed rule would revise confidentiality provisions 
in existing rules. In some cases, the proposed revisions would replace 
existing provisions with a cross reference to the proposed new part 
703. In others, more specific and extensive revision is proposed.
1. Proposed Revisions to 40 CFR Parts 702, 704, 707, 716, 717, 723, and 
790
    EPA is proposing to revise the following provisions to reference 
the general CBI provisions in the proposed new part 703:
     40 CFR 702.37(d), the confidentiality provisions for 
manufacturer requests for risk evaluations;
     40 CFR 704.7, the confidentiality provision for TSCA 
section 8(a) rules;
     40 CFR 707.75(d), the confidentiality provision of rules 
concerning TSCA section 12(b) notices of export;
     40 CFR 716.55, the confidentiality provisions for TSCA 
section 8(d) reporting rules;
     40 CFR 717.19, the confidentiality provision for TSCA 
section 8(c) recordkeeping and reporting rules;
     40 CFR 723.50(l) and 723.250 (f), the confidentiality 
provision for certain exemption requests under TSCA section 5 (low 
volume exemption and low releases and low exposures exemption); and
     40 CFR part 790, the confidentiality provision of rules 
concerning TSCA section 4 test rules, orders, and agreements.
2. Further Clarification Proposed for 40 CFR Part 707
    EPA is proposing to revise the provision concerning the contents of 
TSCA section 12(b) notices of export, 40 CFR 707.67(a), by adding a 
sentence to provide that in most cases, a confidential specific 
chemical identity need not be included in the notice (the primary 
exception would be in the case where the substance to be reported under 
TSCA section 12(b) is claimed as confidential but does not have a TSCA 
accession number). Instead, the TSCA section 12(b) notice of export may 
identify the substance by the generic name and accession number that 
appeared in the TSCA section 4, 5, 6, or 7 action that triggered the 
TSCA section 12(b) reporting requirement. EPA anticipates that with 
this change, TSCA section 12(b) submitters would submit fewer 
confidentiality claims for specific chemical identity, which in almost 
all cases is unnecessary to report under the existing TSCA section 
12(b) rules.
3. Proposed Revision in 40 CFR 717.17 and 723.250 To Reflect Electronic 
Reporting
    EPA proposes to modify 40 CFR 717.17 and 723.250(f) to reflect the 
proposed new electronic reporting requirement discussed in Unit II.C.5.
4. Proposed Revisions to Confidentiality Provisions in the PMN Rules
    EPA is proposing to simplify and replace many of the 
confidentiality provisions in 40 CFR part 720, subpart E with a cross 
reference to the general confidentiality provisions in proposed new 
part 703. The general provisions on confidentiality in PMNs, 40 CFR 
720.80, is proposed to be replaced with this cross reference. 
Requirements in 40 CFR 720.85 and 720.90 are proposed to be deleted, 
with portions moved to 40 CFR part 720, subpart F, the provisions 
concerning NOCs.
    The existing provisions concerning chemical identity claims in PMNs 
and in health and safety studies would be covered in the proposed new 
part 703. In addition, TSCA section 14(c)(2)(G) created an exemption 
from the substantiation requirement for confidentiality claims for 
chemical identity when identity information is submitted before 
substance is offered for commercial distribution. The CBI claim review 
provisions of TSCA section 14(g) exclude these exempt claims from 
routine EPA review requirements, diminishing the need to elaborate on 
requirements for asserting and maintaining such claims in the PMN 
rules.
    Relatedly, a confidentiality claim review process in existing 40 
CFR 720.90, whereby claims that were made in health and safety studies 
in the PMN are revisited at the NOC stage, is a poor fit with new TSCA 
section 14(g) requirements that confidentiality claims

[[Page 29090]]

be reviewed within 90 days of receipt, or in accordance with the 
discretionary or mandatory provisions of TSCA section 14(f). In 
practice, PMNs and NOCs (the latter of which may be submitted many 
months or years after the corresponding PMN, if at all) are treated by 
EPA as separate submissions for the purposes of routine CBI review. At 
the PMN stage, chemical identity claims, including claims made in 
health and safety studies, are generally exempt from review, per the 
exemptions from substantiation and review set out in TSCA sections 
14(c) and (g). NOCs, on the other hand, do not include health and 
safety information. With the proposed deletion of 40 CFR 720.90, the 
review of confidentiality claims in NOC submissions would be limited to 
the information included in the NOC submission--principally chemical 
identity and submitting company information. Claims that were made in 
the PMN submission may be revisited at a later time, in accordance with 
either mandatory or discretionary review provisions in TSCA section 
14(f).
5. PMN NOC Provisions
    The proposed rule leaves much of 40 CFR part 720, subpart F, 
intact, but reorganizes some provisions that concern specific chemical 
identity claims in or following submission of an NOC. These provisions 
are presently in subpart E and would move to subpart F. Additionally, 
the proposed revisions would update and clarify NOC reporting 
instructions in 40 CFR 720.102(c)(2), concerning the assertion and 
substantiation of confidentiality claims throughout the NOC reporting 
form. The existing rule only reflects the substantiation requirements 
that pre-dated the Lautenberg amendments, which were limited to 
specific chemical identity confidentiality claims, and do not reflect 
the newer generic name and certification requirements in TSCA section 
14(c).
    Revisions include adding a new paragraph (e) in 40 CFR 720.102, the 
substance of which is currently in 40 CFR 720.85(b)(3), concerning 
requirements that apply when asserting a confidentiality claim for 
chemical identity in the period after commencing commercial 
manufacture. Additionally, there is a cross-reference to the 
requirements of proposed new part 703, which, among other things, would 
replace the list of substantiation questions currently in 40 CFR 720.85 
(which under existing rules, only apply to chemical identity claims in 
NOCs).
    Finally, the proposed revisions to 40 CFR 720.102 would include a 
new paragraph (f), concerning generic names. These provisions are 
intended to be consistent with generic name provisions in proposed new 
part 703, but include some additional provisions specific to the 
submission and review of generic names for the purposes of listing on 
the TSCA Inventory, including additional procedures intended to aid the 
prompt negotiation by the submitter and EPA of more difficult generic 
names (which are themselves based in part on procedures presently in 40 
CFR 720.85), and a provision that NOCs will be temporarily held in 
situations where the submitter has not provided an acceptable generic 
name despite the negotiation. If the submission is not corrected, EPA 
would proceed with review of the CBI claim for chemical identity and 
would likely deny the claim. EPA invites comments on these and other 
possible approaches to efficiently developing an acceptable generic 
name for purposes of listing on the TSCA Inventory.
6. Microorganisms
    EPA is proposing to replace much of the confidentiality provisions 
currently in 40 CFR part 725, subpart C, with a new, simplified subpart 
C, which largely relies on a cross-reference to the proposed new 
general confidentiality provisions to be placed in proposed new part 
703. The proposed amendments would remove current provisions that are 
inconsistent with the Lautenberg amendments, such as existing 
requirements to provide upfront substantiation of organism identity 
confidentiality claims prior to the commencement of commercial 
manufacture. The proposed rule also proposes some adjustments to the 
general confidentiality provisions in proposed new part 703 when they 
are applied to genetically modified microorganisms and other products 
of biotechnology covered by 40 CFR part 725. These include some 
adjustments to the substantiation questions to reflect some practical 
differences between these products and other types of TSCA chemical 
substances.
    The proposed rule also includes proposed revisions to 40 CFR 
725.190, concerning NOCs, that are similar to the proposed revisions to 
the parallel conventional chemical NOC provisions in 40 CFR 720.102, 
including some elaboration on what must be included in a generic name. 
As in the case with NOCs relating to PMNs, EPA proposes to update 40 
CFR 725.190 to be generally consistent with generic name provisions in 
proposed new part 703, but with some additional provisions specific to 
the review of generic names for the purposes of listing on the TSCA 
Inventory, including additional procedures intended to aid the prompt 
negotiation of more difficult generic names, and a provision that NOCs 
will be held in situations where the submitter has not provided an 
acceptable generic name despite the negotiation (and that such 
deficiencies, if not promptly corrected, may result in denial of the 
claim). EPA invites comments on these and other possible approaches to 
efficiently developing an acceptable generic name for purposes of 
listing on the TSCA Inventory.
7. Changes in Proposed Regulations
    This action proposes a significant number of new and revised CBI 
provisions to be included in proposed new part 703 and proposes to 
revise confidentiality provisions in other existing regulatory 
provisions to cross reference the proposed new part 703. EPA recognizes 
that during the pendency of this rulemaking process, EPA is developing 
other rulemakings that may address confidentiality provisions. For 
example, EPA is developing a proposed rule regarding asbestos reporting 
under TSCA section 8(a). Until this CBI rule is finalized, however, 
additional regulations proposed or finalized need to refer to the 
existing CBI regulations, rather than to the new and revised CBI 
provisions addressed in this rulemaking. EPA requests comment on 
options for harmonizing such provisions. Specifically, EPA requests 
comment on using this action to make any needed conforming amendments, 
e.g., adding cross references to the new and revised CBI provisions 
proposed here to any CBI provisions finalized during the pendency of 
this action including any CBI provisions finalized in the asbestos TSCA 
section 8(a) rule.

III. 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. 2). In addition to specific requests for comment included 
throughout this document, EPA is interested in comments pertaining to 
specific issues discussed in this unit. EPA encourages all interested 
persons to submit comments on the issues identified in this proposed 
rule 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 rulemaking. EPA requests that commenters 
making specific recommendations include supporting

[[Page 29091]]

documentation where appropriate. EPA invites specific comment on:
     EPA's interpretation of the coverage of TSCA section 14(a) 
(proposed section 703.1), and how this may impact submitters of 
information to the Agency under other statutes, such as FIFRA. EPA is 
particularly interested in comments on the treatment of FIFRA studies 
on inert ingredients under TSCA section 14(b)(2).
     The applicability of the proposed new or revised 
requirements to submissions received before the effective date of the 
subsequent final rule. Specifically, EPA requests comment on whether 
each proposed new or revised requirement should apply only to 
submissions received on or after the effective date of the final rule; 
to all submissions received on or after the effective date of the 
Lautenberg amendments; or to all submissions regardless of submission 
date.
     The proposed substantiation questions (proposed section 
703.5(b)), especially the proposal to omit a trade secrets-specific 
question; on how the patents question might be modified to elicit more 
pertinent information; and comment on the alternative substantial 
competitive harm question.
     The proposed list of information that might be included 
with health and safety information, but that might be permissible to 
withhold as confidential (proposed section 703.5(b)(6)). EPA is also 
interested in comment on alternatives to the proposal that might better 
assure that health and safety information is not inappropriately 
treated as confidential.
     The proposed approach to CBI claim deficiencies (proposed 
section 703.5(e)) and on alternative approaches.
     Whether submitting templated data should be required 
(proposed section 703.5(g)).
     The option of requiring TSCA submitters to update their 
original submission to reflect CBI claims that have been withdrawn or 
denied (proposed section 703.5(j)).
     Selection of the representative subset, including possible 
alternative representative selection methods (proposed section 703.7).
     Whether bona fide or pre-notice inquiries or 
correspondence should be considered part of a representative subset of 
TSCA submissions (proposed section 703.7).
     On the proposed approach to determining when a TSCA 
section 14(g) CBI review period begins and how amendments to the 
submission are included in the review (proposed section 703.7).
     The proposed and alternative possible approaches to 
efficiently developing an acceptable generic name for purposes of 
listing on the TSCA Inventory, as described in proposed sections 
720.102 and 725.190.
     On how to incorporate whether a substance may be readily 
reverse engineered into the Agency's substantive review criteria in 
proposed section 703.7(f).

V. Statutory and Executive Orders 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. 2), which is available in 
the docket and is summarized in Unit I.D. 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 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 No. 2706.01 (Ref. 12). You can find 
a copy of the ICR in the docket for this action, and it is briefly 
summarized here.
    The reporting requirements identified in this proposed rule 
implement statutory requirements in TSCA section 14, including new 
requirements that persons submitting information under

[[Page 29092]]

TSCA must substantiate most confidentiality claims at the time of 
submission, as well as additional certification and generic name 
requirements. In order to maintain most claims beyond a 10-year period, 
submitters will also be required to reassert and substantiate those 
claims. Several new requirements also apply to EPA, including 
requirements to review and approve or deny all chemical identity claims 
asserted concerning substances that are offered for commercial 
distribution, as well a subset of all other confidentiality claims, 
within 90 days of the claim being asserted. Further requirements that 
EPA review all confidentiality claims concerning substances listed as 
active on the TSCA Inventory, a requirement to assign and apply unique 
identifiers (UIDs) to substances with approved confidentiality claims 
for chemical identity, as well as new provisions providing expanded 
access to TSCA Confidential Business Information (CBI), have been 
discussed in previous Federal Register documents. Additionally, TSCA 
rules promulgated since the Lautenberg amendments have included 
confidentiality provisions conforming to the amendments (e.g., 40 CFR 
parts 710 and 711).
    Respondents/affected entities: Firms asserting claims for 
confidentiality in submissions to EPA under TSCA.
    Respondent's obligation to respond: Required to obtain or retain a 
benefit. TSCA section 14; 15 U.S.C. 2613.
    Estimated number of respondents: 1,100 firms with an estimated 
additional 55 new firms each year.
    Frequency of response: On occasion.
    Total estimated burden: 2,945 hours paperwork burden in the first 
year and 523 hours in each following year. Burden is defined at 5 CFR 
1320.3(b).
    Total estimated cost: $ 270,783 in the first year and $ 44,605 in 
each following year (2020$), and an estimated cost of $ 0 for non-
burden hour paperwork costs, e.g., capital investment or maintenance 
and operational 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 EPA's 
regulations in title 40 of the CFR, after appearing in the Federal 
Register, are listed in 40 CFR part 9, and displayed on the information 
collection instruments (e.g., forms, instructions).
    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 EPA using the docket identified at 
the beginning of this proposed rule. You may also send your ICR-related 
comments to OMB's Office of Information and Regulatory Affairs using 
the interface at https://www.reginfo.gov/public/do/PRAMain. Find this 
particular ICR by selecting ``Currently under Review--Open for Public 
Comments'' or by using the search function. Since OMB is required to 
make a decision concerning the ICR between 30 and 60 days after 
receipt, OMB must receive comments no later than June 13, 2022. The EPA 
will respond to 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 chemical manufacturers (including importers). EPA 
estimates that 1,096 small firms would be affected by the proposed 
requirements. Of those small firms, 100% would have cost impacts of 
less than 1% of annual revenues, which EPA has determined does not 
qualify as a significant impact. Details of this analysis are presented 
in the Economic Analysis of the proposed rule (Ref. 2), 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 action imposes 
no enforceable duty on any state, local or tribal governments or the 
private sector.

E. Executive Order 13132: Federalism

    This action does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 4, 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 does not have 
substantial direct effects on tribal government because asbestos is not 
manufactured (including imported) or processed by tribes and would not 
impose substantial direct compliance costs on tribal governments.

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

    The 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 EPA has reason to believe 
may disproportionately affect children, per the definition of ``covered 
regulatory action'' in section 2-202 of the Executive Order. This 
action is not subject to Executive Order 13045 because it does not 
concern an environmental health risk or safety risk.

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

    This action is not a ``significant energy action'' under 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.'' The action is predicted to reduce energy use and is 
not expected to reduce energy supply or increase energy prices.

I. National Technology Transfer and Advancement Act (NTTAA)

    This proposed action does not involve any technical standards as 
specified in NTTAA section 12(d), 15 U.S.C. 272 note.

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

    The 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).

2. Revise Sec.  2.306 to read as follows:


Sec.  2.306   Special rules governing certain information obtained 
under the Toxic Substances Control Act.

    (a) Definitions. For the purposes of this section:
    (1) Act means the Toxic Substances Control Act, 15 U.S.C. 2601 et 
seq.
    (2) Chemical substance has the meaning given it in section 3(2) of 
the Act, 15 U.S.C. 2602(2).
    (3) EPA Legal Office means the EPA Office of General Counsel and 
any EPA office over which the EPA General Counsel exercises supervisory 
authority.
    (4) Proceeding means any rulemaking, adjudication, or licensing 
conducted by EPA under the Act or under regulations which implement the 
Act, except for determinations under this subpart.
    (b) Applicability. This section applies as set forth in 40 CFR 
703.1.
    (c) Basic rules that apply without change. Sections 2.210, 2.211, 
2.212, 2.214, and 2.215 apply without change to information to which 
this section applies. Unless otherwise specified in Sec.  2.306, the 
provisions in Sec. Sec.  2.201 through 2.205 and 2.208 do not apply to 
information subject to this section. Instead, the provisions of 40 CFR 
part 703 provide the requirements and procedures relevant to 
confidentiality determinations for information submitted to EPA under 
the Act.
    (d) Disclosure in special circumstances. Disclosures of information 
claimed as confidential under TSCA section 14(d)(4), (5), and (6) may 
be made in accordance with the provisions of the Act, Sec.  2.306 and 
any applicable EPA guidance required by section 14(c)(4)(B) of the Act. 
Section 2.209 applies to information to which this section applies, 
except that:
    (1) The following two additional provisions apply to Sec.  
2.209(c):
    (i) The official purpose for which the information is needed must 
be in connection with the agency's duties under any law for protection 
of health or the environment or for specific law enforcement purposes; 
and
    (ii) EPA notifies the other agency that the information was 
acquired under authority of the Act and that any knowing disclosure of 
the information may subject the officers and employees of the other 
agency to the penalties in section 14(h) of the Act (15 U.S.C. 
2613(h)).
    (2) The 10 business day period for notification specified in Sec.  
2.209(b)(2) is instead 15 business days.
    (3) The timeline for notification in Sec.  2.209(d) is replaced by 
the timeline for notification in 15 U.S.C. 2613(g)(2)(B).
    (e) Disclosure of information relevant in a proceeding. (1) Under 
section 14(d)(7) of the Act (15 U.S.C. 2613(d)(7)), any information to 
which this section applies may be disclosed by EPA when the information 
is relevant in a proceeding under the Act, notwithstanding the fact 
that the information otherwise might be entitled to confidential 
treatment under this subpart. However, any such disclosure shall be 
made in a manner that preserves the confidentiality of the information 
to the extent practicable without impairing the proceeding. Disclosure 
of information to which this section applies because of its relevance 
in a proceeding shall be made only in accordance with this paragraph 
(e).
    (2) The provisions of Sec.  2.301(g)(2) through (4) apply to 
disclosures under this paragraph (e).
    (f) Disclosure of information to contractors and subcontractors. 
(1) Under section 14(d)(2) of the Act (15 U.S.C. 2613(d)(2)), any 
information to which this section applies may be disclosed by EPA to a 
contractor or subcontractor of the United States that is necessary for 
the satisfactory performance of their work in connection with the Act, 
notwithstanding the fact that the information otherwise might be 
entitled to confidential treatment under this subpart. Subject to the 
limitations in this paragraph (f), information to which this section 
applies may be disclosed:
    (i) To a contractor or subcontractor with EPA, if the EPA program 
office managing the contract first determines in writing that such 
disclosure is necessary for the satisfactory performance by the 
contractor or subcontractor of the contract or subcontract; or
    (ii) To a contractor or subcontractor with an agency other than 
EPA, if the EPA program office which provides the information to that 
agency, contractor, or subcontractor first determines in writing, in 
consultation with the General Counsel, that such disclosure is 
necessary for the satisfactory performance by the contractor or

[[Page 29094]]

subcontractor of the contract or subcontract.
    (2) The provisions of Sec.  2.301(h)(2)(ii) through (iv) apply to 
disclosures under this paragraph (f).
    (3) At the time any information is furnished to a contractor or 
subcontractor under this paragraph (f), the EPA office furnishing the 
information to the contractor or subcontractor shall notify the 
contractor or subcontractor that the information was acquired under 
authority of the Act and that any knowing disclosure of the information 
may subject the contractor or subcontractor and its employees to the 
penalties in section 14(d) of the Act (15 U.S.C. 2613(d)).
    (g) Disclosure of information when necessary to protect health or 
the environment against an unreasonable risk of injury. (1) Under 
section 14(d)(3) of the Act (15 U.S.C 2613(d)(3)), any information to 
which this section applies may be disclosed by EPA when disclosure is 
necessary to protect health or the environment against an unreasonable 
risk of injury to health or the environment, without consideration of 
costs, or other non-risk factors, including an unreasonable risk to a 
potentially exposed or susceptible subpopulation as relevant by EPA 
under conditions of use. However, any disclosure shall be made in a 
manner that preserves the confidentiality of the information to the 
extent not inconsistent with protecting health or the environment 
against the unreasonable risk of injury. Disclosure of information to 
which this section applies because of the need to protect health or the 
environment against an unreasonable risk of injury shall be made only 
in accordance with this paragraph (g).
    (2) If any EPA office determines that there is an unreasonable risk 
of injury to health or the environment and that to protect health or 
the environment against the unreasonable risk of injury it is necessary 
to disclose information to which this section applies that otherwise 
might be entitled to confidential treatment under this subpart, the EPA 
office shall notify the EPA Legal Office in writing of the nature of 
the unreasonable risk of injury, the extent of the disclosure proposed, 
how the proposed disclosure will serve to protect health or the 
environment against the unreasonable risk of injury, and the proposed 
date of disclosure. Such notification shall be made as soon as 
practicable after discovery of the unreasonable risk of injury. If the 
EPA office determines that the risk of injury is so imminent that it is 
impracticable to furnish written notification to the EPA Legal Office, 
the EPA office shall notify the EPA Legal Office orally.
    (3) Upon receipt of notification under paragraph (g)(2) of this 
section, the EPA Legal Office shall make a determination in writing 
whether disclosure of information to which this section applies that 
otherwise might be entitled to confidential treatment is necessary to 
protect health or the environment against an unreasonable risk of 
injury. The EPA Legal Office shall also determine the extent of 
disclosure necessary to protect against the unreasonable risk of injury 
as well as when the disclosure must be made to protect against the 
unreasonable risk of injury.
    (4) If the EPA Legal Office determines that disclosure of 
information to which this section applies that otherwise might be 
entitled to confidential treatment is necessary to protect health or 
the environment against an unreasonable risk of injury, the EPA Legal 
Office shall furnish notice to each affected business of the 
contemplated disclosure and of the Legal Office's determination. Such 
notice shall be made in writing, via either electronic notice as 
described in 40 CFR 703.5(h) or by certified mail, return receipt 
requested, at least 15 business days before the disclosure is to be 
made. The notice shall state the date upon which disclosure will be 
made. However, if the EPA Legal Office determines that disclosure of 
the information is necessary to protect against an imminent and 
substantial harm to health or the environment, no prior notification is 
necessary.

PART 703--CONFIDENTIALITY CLAIMS

Sec.
703.1 Purpose and applicability.
703.3 Definitions.
703.5 Requirements for asserting and maintaining confidentiality 
claims.
703.7 EPA review of confidentiality claims under TSCA Section 14(g).
703.8 EPA review of confidentiality claims under TSCA Section 14(f).

    Authority:  15 U.S.C. 2613.


Sec.  703.1   Purpose and applicability.

    (a) The purpose of this part is to describe procedures for 
asserting and maintaining confidentiality claims in accordance with 
TSCA section 14, and for EPA review of such claims. The procedures 
described in this part are generally applicable to the submission and 
EPA review of any TSCA submission, except to the extent that 
application of the requirements would be inconsistent with TSCA section 
14(i). The procedures include requirements concerning the form and 
manner in which TSCA submissions must be made to meet the requirements 
in TSCA section 14(b) and (c), to facilitate EPA review of such claims 
in accordance with TSCA section 14(f) and (g), and to facilitate 
disclosure of non-confidential information to the public in accordance 
with TSCA, FOIA, and their implementing regulations.
    (b) This part applies to all information that is reported to or 
otherwise obtained by EPA pursuant to TSCA or its implementing 
regulations. Unless otherwise specified in 40 CFR 2.306, the provisions 
of 40 CFR 2.201 through 2.205 and 40 CFR 2.208 do not apply to 
information subject to this part. This part also applies to information 
that satisfies all three of the following criteria:
    (1) The information was first obtained by EPA other than pursuant 
to the authority of TSCA or its implementing regulations;
    (2) EPA has authority to collect the information under TSCA; and
    (3) Either:
    (i) Subsequent to its submission the information is being used to 
satisfy the obligation of a person under TSCA or its implementing 
regulations; or
    (ii) EPA makes use of the information in the course of carrying out 
its responsibilities under TSCA.
    (c)(1) This part applies regardless of:
    (i) Whether the information is intended by its submitter to be used 
by EPA in implementing TSCA;
    (ii) Whether TSCA or an implementing regulation was cited as 
authority for the request or submission of the information; or
    (iii) Whether the information was provided directly to EPA or 
through some third person.
    (2) In the event the information satisfies the requirements of 
Sec.  703.1, and such information was originally submitted to or 
obtained by EPA under

[[Page 29095]]

another statute, and the other statute or its implementing regulations 
prescribe conflicting rules for the treatment of the information, the 
statute or rule under which the information was provided to EPA shall 
govern, except that the provisions in 40 CFR 2.306(d) through (f) 
apply, where relevant, to how EPA may share such information.


Sec.  703.3   Definitions.

    The definitions in this section and the definitions in TSCA section 
3 apply to this part. In addition, the definition in Sec.  720.3(ff) 
for test data also applies in this part.
    Accepted in the context of asserting a TSCA CBI claim means the 
date that EPA first approved the submission in CISS, or its successor 
system.
    CDX or Central Data Exchange means EPA's centralized electronic 
document receiving system, or its successor system.
    CISS or Chemical Information Submission System means EPA's web-
based reporting tool for preparing and submitting TSCA submissions, or 
its successor system.
    Confidentiality claim means a claim or allegation that business 
information is entitled to confidential treatment.
    Health and safety study has the same meaning as that provided in 
Sec.  720.3(k), except that for purposes of this part 703 the following 
information is not part of a health and safety study:
    (1) The name of the submitting company;
    (2) The name of the laboratory conducting the study;
    (3) Internal product codes;
    (4) The names of laboratory personnel;
    (5) Names of individual study subjects and other private 
information included in study data or reports;
    (6) Cost and other financial data; and
    (7) Product development, advertising, and marketing plans.


Sec.  703.5   Requirements for asserting and maintaining 
confidentiality claims.

    Any person who submits information under TSCA or these implementing 
regulations may assert a business confidentiality claim to information 
included in such submission. Such claim must be made concurrent with 
submission of the information. If no such claim accompanies the 
submission, EPA will not recognize a confidentiality claim, and the 
information in or referred to in that submission may be made available 
to the public (e.g., by publication of specific chemical name and CASRN 
on the public portion of the TSCA Inventory) without further notice.
    (a) Supporting statement and certification. A person asserting a 
confidentiality claim must submit a statement that the person has:
    (1) Taken reasonable measures to protect the confidentiality of the 
information;
    (2) Determined that the information is not required to be disclosed 
or otherwise made available to the public under any other Federal law;
    (3) A reasonable basis to conclude that disclosure of the 
information is likely to cause substantial harm to the competitive 
position of the person; and
    (4) A reasonable basis to believe that the information is not 
readily discoverable through reverse engineering.
    (5) The person must also certify that these four statements and any 
information required to substantiate the confidentiality claim in 
accordance with paragraph (b) of this section are true and correct.
    (b) Substantiation. (1) Timing of substantiation. Confidentiality 
claims must be substantiated at the time of submission to EPA, unless 
exempt under paragraph (b)(5) of this section. In the case of 
information collected by EPA or on behalf of EPA in person at the site 
of a TSCA inspection under section 11 of the Act, the affected company 
must assert its confidentiality claim(s) in writing at the time the 
information is collected, and then must provide substantiation of its 
confidentiality claims and the supporting statement and certification 
described in paragraph (a) of this section within ten working days 
after the inspection ends.
    (2) Confidentiality claims in substantiation. Information in 
substantiations may be claimed as confidential. Such claims must be 
accompanied by the certification described in paragraph (a) of this 
section, but need not be themselves substantiated.
    (3) Substantiation questions for all claims. Unless otherwise 
specified elsewhere in 40 CFR 700 et seq (e.g., 40 CFR part 711), 
answers to the following questions must be provided for each 
confidentiality claim in a TSCA submission:
    (i) Please specifically explain what harm to the competitive 
position of your business would be likely to result from the release of 
the information claimed as confidential. How would that harm be 
substantial? Why is the substantial harm to your competitive position 
likely (i.e., probable) to be caused by release of the information 
rather than just possible? If you claimed multiple types of information 
to be confidential (e.g., site information, exposure information, 
environmental release information, etc.), explain how disclosure of 
each type of information would be likely to cause substantial harm to 
the competitive position of your business.
    (ii) 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. If the same or similar information 
was previously reported to EPA as non-confidential (such as in an 
earlier version of this submission), please explain the circumstances 
of that prior submission and reasons for believing the information is 
nonetheless still confidential.
    (iii)(A) Is any of the information claimed as confidential required 
to be publicly disclosed under any other Federal law? If yes, please 
explain.
    (B) 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.
    (C) 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.
    (iv) 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 1 and 10 years) or the specific date after 
which the claim is withdrawn.
    (v) 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 determination.
    (4) Additional substantiation questions for chemical identity-
related claims only. Unless otherwise specified in the relevant 
electronic reporting form, answers to the following questions must be 
provided for each chemical

[[Page 29096]]

identity-related confidentiality claim in a TSCA submission:
    (i) 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 and have no knowledge of public information that 
would indicate that the chemical is being manufactured or imported 
by anyone for a commercial purpose in the United States. [provide 
date].

    (ii) Does this specific 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.
    (iii) 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.
    (iv) Would disclosure of the specific chemical identity release 
confidential process information? If yes, please explain.
    (5) Exemptions from the substantiation requirement. Information 
described in paragraphs (b)(5)(i) and (b)(5)(ii) of this section is 
exempt from the requirement to substantiate the claim at the time of 
submission. EPA may identify on a reporting form certain information as 
exempt from substantiation. Additional assertions of exemption from 
substantiation may be asserted by the submitter. Each such assertion 
must include a detailed explanation for why the information falls 
within the claimed exemption. If the explanation is missing or 
inadequate, and the claim is not otherwise substantiated, EPA will 
place a hold on the submission, as described in paragraph (d) of this 
section.
    (i) The following information types are exempt from the 
substantiation requirement at the time of information submission:
    (A) Specific information describing the processes used in 
manufacture or processing of a chemical substance, mixture, or article;
    (B) Marketing and sales information;
    (C) Information identifying a supplier or customer;
    (D) Details of the full composition of a mixture and the respective 
percentages of constituents;
    (E) Specific information regarding the use, function, or 
application of a chemical substance or mixture in a process, mixture, 
or article; and
    (F) Specific production or import volumes.
    (ii) Exemption for chemical substances not yet offered for 
commercial distribution.
    (A) A confidentiality claim for specific identity of a chemical 
substance, where the submission is made prior to the date on which the 
chemical substance whose identity is claimed as confidential is first 
offered for commercial distribution, is exempt from the requirement to 
substantiate confidentiality claims at the time of submission.
    (B) A specific chemical identity claim includes specific chemical 
names, CAS numbers, molecular formulas, reactants (if required to be 
reported as part of the identification of the chemical, such as for 
Class 2 substances in Sec.  720.45(a)), and structural diagrams; or in 
the case of microorganisms, genus and species name and genetic 
construct.
    (C) This exemption applies where the submitter lacks information to 
reasonably conclude that the chemical substance has been offered for 
commercial distribution, where both:
    (1) The chemical substance is not on the TSCA Inventory, and
    (2) The substance is otherwise not publicly known to have been 
offered for commercial distribution.
    (c) Public copies. All TSCA submissions and their accompanying 
attachments that include a confidentiality claim must be accompanied, 
at the time of submission, by a public version of the submission and 
any attachments, with all information that is claimed as confidential 
removed. In the case of documents collected by EPA or on behalf of EPA 
in person at the site of a TSCA inspection under section 11 of the Act, 
the affected company must provide such public copies at the same time 
as it provides substantiation of its confidentiality claims in 
accordance with paragraph (b)(1) of this section, within ten working 
days after the inspection ends. Only information that is claimed as 
confidential may be redacted or removed. Generally, a public copy that 
removes all or substantially all of the information would not meet the 
requirements of this paragraph (c) of this section and the submission 
may be temporarily put on hold as deficient.
    (1) Where the applicable reporting form or electronic reporting 
tool contains a checkbox or other means of designating with specificity 
what information is claimed as confidential, no further action by the 
submitter is required to satisfy this requirement.
    (2) For all other information claimed as confidential, including 
but not limited to information in attachments and in substantiations 
required under paragraph (b) of this section, the submitter must 
prepare and attach a public copy. EPA may hold as deficient submissions 
with public or sanitized copies that are entirely blank or that are 
substantially reduced in length as compared to the CBI version (see 
paragraph (e) of this section).
    (d) Generic name. Each confidentiality claim for specific chemical 
identity must be accompanied by a structurally descriptive generic name 
for that substance. This generic name must be consistent with guidance 
on the determination of structurally descriptive generic names 
developed in accordance with TSCA section 14(c)(4)(A) (e.g., Guidance 
for Creating Generic Names for Confidential Chemical Substance Identity 
Reporting under TSCA; available at https://www.epa.gov/tsca-inventory/guidance-creating-generic-names-confidential-chemical-substance-identity-reporting), and 15 U.S.C. 2613(c)(1)(C)(ii).
    (1) At a minimum, the generic name must either:
    (i) Be identical to the generic name for the same substance 
included on the non-confidential portion of the TSCA Inventory (if the 
substance is listed on the TSCA Inventory), or
    (ii) For substances that are not listed on the TSCA Inventory, mask 
only the confidential portions of the specific chemical name. In most 
cases, only one structural element of a specific chemical name may be 
masked to protect a confidential chemical identity--if the submitter of 
a proposed generic name wishes to mask more than one such element, the 
submission must include an explanation of why masking only one element 
is insufficient to protect the confidential identity.
    (2) Notwithstanding paragraph (d)(1) of this section, EPA may 
conclude that a generic name provided with the submission and listed on 
the current non-confidential version of the TSCA

[[Page 29097]]

Inventory does not comply with 15 U.S.C. 2613(c)(1)(C). In such cases, 
EPA will notify the submitting company and proceed as described in 
paragraph (c)(4) of this section.
    (3) A generic name that meets the requirements of section 
14(c)(1)(C) of the Act prior to the date on which the chemical 
substance is first offered for commercial distribution for the purposes 
of a pre-market submission (e.g., a PMN) may not be sufficient for the 
purposes of subsequent listing on the TSCA Inventory, as identified 
upon review under section 14(g)(1)(C)(i) of the Act of a 
confidentiality claim for specific chemical identity made in a Notice 
of Commencement required under Sec.  720.102 or Sec.  725.190(f). In 
such cases, EPA will notify the submitting company and proceed as 
described in Sec.  720.102(f) or Sec.  725.190(f).
    (4) If EPA concludes that the proposed generic name does not comply 
with 15 U.S.C. 2613(c)(1)(C), EPA will notify the submitter, and 
provide 10 business days for the submitter to provide a revised generic 
name. If EPA concludes that the revised generic name is still not 
acceptable, EPA will hold the submission for an additional period of up 
to 10 business days, and proceed as set out in paragraph (e) of this 
section.
    (e) Deficient confidentiality claims. (1) A confidentiality claim 
under TSCA is deficient if it meets one or more of the following 
criteria:
    (i) The confidentiality claim is not accompanied by the supporting 
statement and certification required by paragraph (a) of this section.
    (ii) The confidentiality claim is not accompanied by the 
substantiation required by paragraph (b) of this section. If the 
submitter claims an exemption from substantiation under paragraph 
(b)(5) of this section and the exemption does not apply or an 
explanation is not provided for the exemption pursuant to paragraph 
(b)(5) of this section, the confidentiality claim is deficient.
    (iii) The confidentiality claim is not accompanied by a public copy 
that meets the requirements of paragraph (c) of this section.
    (iv) The confidentiality claim is for a specific chemical identity 
and is not accompanied by a generic name that meets the requirements of 
paragraph (d) of this section.
    (2) A submission that is identified as deficient under paragraph 
(e)(1) of this section will be held for a period of up to 10 business 
days, and the submitter will be notified via CDX as described in 
paragraph (h) of this section. During the hold, which commences on the 
day the CDX notice is sent, any applicable review period for the 
underlying submission will be suspended until either the deficiency is 
corrected or the 10 business days elapse without such correction. Upon 
the occurrence of the first of either of these events, the applicable 
review period for the underlying submission commences or comes out of 
suspension. If the deficiency is not remedied during the suspension, 
EPA will proceed with review of the submission and may deny the CBI 
claim(s).
    (f) Electronic reporting required. (1) Except in the case of 
information subpoenaed under TSCA section 11(c) or materials collected 
or requested by EPA as part of an inspection under TSCA section 11(a), 
TSCA submissions bearing confidentiality claims must be submitted via 
CDX.
    (2) You must use CISS to complete and submit TSCA submissions via 
CDX. To access CISS go to https://cdx.epa.gov/ and follow the 
appropriate links.
    (3) On receipt by EPA, each electronic TSCA submission will be 
assigned a case number or document identifier, which will be available 
to the submitter in their CDX account. This identifier may be used as a 
reference in future communications that concern the substance, and may 
be used by EPA in public communications (e.g., Federal Register 
notices) that concern the submission, such as notices of receipt, final 
confidentiality determination, pending confidentiality claim 
expiration, or in other regulatory actions that concern the TSCA 
submission.
    (g) Requirement to report health and safety studies using 
templates. Submitters of health and safety studies or information from 
such studies must provide such data in templated form, using an 
appropriate OECD harmonized template, if such template is available for 
the data type (https://www.oecd.org/ehs/templates/). Individual test or 
data submission rules or orders may specify an appropriate template or 
templates. Submission of templated data is not a substitute for 
submitting a full study report where a specific TSCA rule or order 
requires submission of the full study report (e.g., Sec.  720.50(a), or 
according to the terms of a specific order under TSCA section 5(e)).
    (h) Requirement to maintain company contact information; electronic 
notices concerning confidentiality claims. (1) To facilitate ongoing or 
future communication concerning TSCA submissions, current contact 
information for all of the individuals associated with a particular 
TSCA submission must be maintained. Contact information for all the 
individuals associated with a particular TSCA submission must be 
updated by amending the submission via CDX, except that submissions 
that are either no longer accessible to the submitting company or that 
were not submitted via CDX (e.g., submissions that were originally 
provided on paper or other physical media), updated company contact 
must be provided via CDX using the appropriate EPA-provided electronic 
reporting application in CISS. In circumstances where ownership of the 
company or unit of a company has changed, such that contact information 
for one or more prior TSCA submissions that include confidentiality 
claims is affected, a notice of transfer of ownership must be directed 
to EPA via CDX. Instructions for providing this notice and for 
requesting access to copies of a prior TSCA submission are available at 
https://cdx.epa.gov/.
    (2) When EPA contacts a TSCA submitter concerning confidentiality 
claims (e.g., related to a pending or concluded confidentiality claim 
review, a deficient submission, or in relation to the 10-year 
expiration of a confidentiality claim (described in TSCA section 
14(e)), EPA may provide notices and other correspondence to the 
submitter via CDX, using the contact information provided in the most 
recent version of the submission, or using the contact information 
provided in a more recent notice of transfer of ownership relating to 
that submission. The fact and date of delivery of such notice is 
verified automatically by CDX.
    (3) In addition to individual notice described in paragraph (h)(2) 
of this section, EPA will publish on its website, or other appropriate 
platform, a list of TSCA submissions with confidentiality claims that 
are approaching the end of the ten-year period of protection described 
in TSCA section 14(e). Such TSCA submissions will be referred to by the 
TSCA case or document identifier (as described in paragraph (f)(3) of 
this section) that was assigned to the submission by EPA when it was 
originally submitted. TSCA submissions will be added to this list at 
least 60 days prior to the end of the ten-year period of protection, 
along with instructions for reasserting and substantiating expiring 
claims.
    (4) When a confidentiality claim is being reviewed pursuant to TSCA 
section 14(f), EPA will provide, when necessary, notice of such review 
and an opportunity to substantiate or resubstantiate the affected 
confidentiality claim to the submitter using the contact information 
for the authorized official or technical contact provided in the most 
recent version of the submission or in a more recent

[[Page 29098]]

notice of transfer of ownership relating to that submission.
    (5) Where the submission with the relevant CBI claim was not 
originally made via CDX, EPA will send the notice via courier or US 
Mail to the company address provided in the most recent TSCA submission 
made by that company, or via other means that allows verification of 
the fact and date of receipt. The notice will provide instructions for 
substantiating claims that were exempt from substantiation when the 
confidentiality claim was asserted or for which the submitter was 
otherwise not required to provide substantiation at the time of initial 
submission, and for updating or re-substantiating as necessary any 
claims that were previously substantiated.
    (i) Withdrawing confidentiality claims. TSCA confidentiality claims 
may be voluntarily withdrawn by the submitter at any time.
    (1) Confidentiality claims in TSCA submissions that were originally 
made via electronic submission may be withdrawn by reopening the 
submission in CDX, removing confidentiality markings (e.g., 
confidential checkmarks or bracketing), revising sanitized attachments 
or copies as appropriate, and then resubmitting the submission.
    (2) For submissions that were not originally made via CDX, or that 
are no longer accessible to the submitting company via CDX, 
confidentiality claims may also be withdrawn via CDX using the ``TSCA 
Communications'' application or successor system. The withdrawal 
correspondence must indicate the case or document number (or other 
applicable document identifier or document identifying details) from 
which CBI claims are being withdrawn, identify the submitting company, 
and include a list or description of the information for which CBI 
claims are being withdrawn, including page numbers where relevant. 
Current contact information for the person withdrawing the claim must 
also be provided, in the event EPA needs clarification concerning which 
claim or claims are being withdrawn.
    (j) Amending public copy following confidentiality claim denial or 
expiration. (1) Following the expiration or EPA's denial of a TSCA 
confidentiality claim, the person who asserted the denied or expired 
claim should prepare and submit a revised public copy of the submission 
to EPA, following the procedures for voluntarily withdrawing claims 
described in Sec.  703.5(i).
    (2) If the person who asserted the denied or expired claim declines 
or fails to provide within 30 days a revised public copy of the 
submission that includes the information for which the confidentiality 
claim(s) were denied or expired, EPA may prepare an addendum to the 
original public copy, as needed, in order to provide the newly 
available information to the public.


Sec.  703.7  EPA review of confidentiality claims under TSCA Section 
14(g)

    (a) Representative subset. (1) Definition. A representative subset 
consists of at least 25% of confidentiality claims asserted under TSCA, 
not including claims for specific chemical identity or for the 
categories of information listed in section 14(c)(2) of TSCA. Excluded 
from the representative subset are
    (i) Inquiries with respect to potential submission to EPA of a 
notification under 40 CFR part 720, 721, 723 or 725 by a person who has 
not submitted the notification at the time of the inquiry, including 
inquiries under Sec.  720.25(b) or 721.11;
    (ii) Submissions or other communication not submitted to EPA via 
CDX; and
    (iii) Amendments to previous TSCA submissions.
    (2) Selection of submissions for review. To satisfy its 
confidentiality claim review obligations under section 14(g)(1)(C)(ii) 
of TSCA, EPA may review all claims (except those exempt from 
substantiation under TSCA section 14(c)(2)) in every fourth TSCA 
submission submitted via CDX that is part of the representative subset, 
in chronological order of receipt by EPA. For each submission selected 
for review as part of the representative subset, EPA reviews and 
approves or denies every individual confidentiality claim in that 
submission (except claims that are exempt under TSCA sections 14(c)(2) 
and 14(g)), including claims made in attachments and amendments 
available to EPA at the time of the review.
    (b) Review of new and expiring confidentiality claims under TSCA 
Section 14(g). (1) Under TSCA Section 14(g), EPA will review:
    (i) All chemical identity claims asserted in TSCA submissions 
except those that are exempt from substantiation according to TSCA 
Section 14(c)(2)(G), and
    (ii) A representative subset of other confidentiality claims as 
provided in paragraph (a) of this section.
    (2) EPA will review all timely requests for extension of claims 
under section 14(e) of TSCA within 30 days of receipt.
    (3) EPA will also review or re-review confidentiality claims under 
certain other circumstances, as set out in TSCA section 14(f). TSCA 
section 14(f) reviews are conducted in accordance with procedures set 
out in Sec.  703.8.
    (c) Commencement of the review period and effect of amendments. 
Subject to Sec.  703.5(e), the 90-day review period described in TSCA 
section 14(g) begins on the day that EPA accepts a new TSCA submission 
that includes confidentiality claims. For new information, other than 
specific chemical identity, added to a submission after EPA first 
accepts the submission, the review will take into account such 
amendments to that submission that are made either up to 60 days from 
the original submission date, or until the Agency issues a final 
confidentiality determination for the submission, whichever comes 
first. If a submission is amended to report an additional or different 
chemical substance that includes a new specific chemical identity 
claim, the TSCA section 14(g) review period for the added chemical 
identity begins on the day EPA accepts the amendment including the new 
claim.
    (d) Publication of final determinations. Final confidentiality 
determinations will be published on EPA's website, or other platform, 
periodically, in accordance with the requirements of TSCA section 
26(j).
    (e) Claim denials and notice period. Final determinations will be 
issued by the General Counsel or their designee, which may include 
personnel outside of the Office of General Counsel. In the case that 
EPA determines that a claim or part of a claim is not entitled to 
confidential treatment, EPA will provide notice of the denial to the 
person who made the claim and provide reasons for the denial or denial 
in part. The notice will be provided electronically, as described in 
Sec.  703.5(h)(2). The 30-day notice period described in TSCA section 
14(g)(2)(B) begins on the next business day following the date the 
notice is made available to the submitter in their CDX account.
    (f) Substantive criteria for use in confidentiality determinations. 
Information claimed as confidential under TSCA section 14 will be 
approved if:
    (1) The business has asserted a business confidentiality claim 
which has not expired by its terms, nor been waived nor withdrawn;
    (2) The business has satisfactorily shown that it has taken 
reasonable measures to protect the confidentiality of the information, 
and that it intends to continue to take such measures for as long as 
the claim is maintained;

[[Page 29099]]

    (3) The information is not, and has not been, reasonably obtainable 
without the business's consent by other persons (other than 
governmental bodies) by use of legitimate means (other than discovery 
based on a showing of special need in a judicial or quasi-judicial 
proceeding; e.g., the business has demonstrated a reasonable basis to 
believe the information is not readily discoverable through reverse 
engineering);
    (4) The business has demonstrated a reasonable basis to conclude 
that disclosure of the information is likely to cause substantial harm 
to the competitive position of the business; and
    (5) No statute denies confidential protection to the information. 
Information from health and safety studies is not entitled to 
confidential treatment, except that the following information may be 
entitled to confidential treatment if it otherwise meets the remainder 
of criteria in this paragraph (f):
    (i) Any information, including formulas (including molecular 
structures) of a chemical substance or mixture, that discloses 
processes used in the manufacturing or processing of a chemical 
substance or mixture; or
    (ii) In the case of a mixture, the portion of the mixture comprised 
by any of the chemical substances in the mixture.
    (g) Request for Reconsideration. Persons who received a denial or 
partial denial notification under paragraph (e) of this section may 
request reconsideration by the Office of General Counsel prior to the 
end of the 30-day period specified in the notice and described under 
paragraph (e) of this section. The business must make its request for 
reconsideration electronically via CDX, following the instructions in 
the notice. If a request for reconsideration is timely received, EPA 
will suspend the 30-day notice period described in paragraph (e) of 
this section while the Office of General Counsel reconsiders the 
Agency's determination. Once the Office of General Counsel's 
reconsideration is complete, the Agency will provide notification, 
pursuant to Sec.  703.5(h), to the person of EPA's decision on the 
request for reconsideration. If upon reconsideration the Agency upholds 
the confidentiality determination, the 30-day notice period will 
resume. The Office of General Counsel will perform its review de novo 
and will only reconsider determinations based on the information 
included with the original submission and amendments made up until the 
time the final determination was issued.
    (h) Criteria to use in consideration of requests for extension 
under TSCA section 14(e). Requests to extend the period of 
confidentiality protection under TSCA section 14(e) use the same 
criteria as described under Sec.  703.7(f). Requests for extension may 
rely on a substantiation previously provided to EPA, but the submitter 
must recertify that the substantiation is still true and correct.


Sec.  703.8  EPA Review of Confidentiality Claims Under TSCA Section 
14(f).

    (a) Review of confidentiality claims initiated under TSCA Section 
14(f). In accordance with the procedures described in this section, EPA 
may review confidentiality claims that are subject to TSCA section 
14(f)(1), and will review confidentiality claims subject to TSCA 
section 14(f)(2) in the following situations:
    (1) In response to a request under the Freedom of Information Act 
(5 U.S.C. 552) for TSCA information claimed confidential;
    (2) If EPA has reason to believe that information claimed 
confidential does not qualify for protection from disclosure; or
    (3) For any chemical substance EPA determines under TSCA section 
6(b)(4)(A) presents an unreasonable risk of injury to health or the 
environment.
    (b) Substantiation exemptions not applicable. All confidentiality 
claims asserted in submissions described by paragraph (a) of this 
section are subject to the substantiation requirements, including those 
that were initially exempt from substantiation according to section 
14(c)(2) of TSCA.
    (c) Additional substantiation. If necessary, such as in the case 
that substantiation has not previously been provided for 
confidentiality claims under review, or in the case that EPA has reason 
to believe the substantiation is incomplete or out of date, EPA will 
request additional substantiation from the person(s) that claimed the 
information as confidential.
    (d) Additional substantiation notice. If additional substantiation 
is necessary, EPA will provide notice to the person that claimed the 
information as confidential in the manner specified in Sec.  
703.5(h)(4). The notice will provide the time allowed for additional 
substantiation from the business and the method for requesting a time 
extension if necessary. If the person does not make a timely response 
or extension request, EPA will consider any existing substantiations in 
its review of the claims or, in the case of any unsubstantiated claim, 
EPA will construe this as a waiver of the claim and may make the 
information public without any further notice to the submitter.
    (e) Substantive criteria for use in confidentiality determinations. 
The criteria in Sec.  703.7(f) apply to confidentiality determinations 
initiated under TSCA section 14(f). For determinations required to 
respond to a FOIA request, the criteria in Sec.  703.7(f) are 
supplemented with one additional criterion that must be satisfied: The 
business adequately demonstrates that the information is commercial or 
financial information obtained from a person and is confidential within 
the meaning of FOIA Exemption 4 (5 U.S.C. 552(b)(4)).
    (f) Adverse determinations and notice period. Final determinations 
will be issued by the General Counsel or their designee, including 
personnel outside of the Office of General Counsel. Except for 
instances where claims were waived, if EPA determines that information 
claimed confidential does not qualify for protection from disclosure, 
EPA will provide written notice to the person who asserted the claim. 
The notice will be provided electronically, as described in Sec.  
703.5(h)(2). The 30-day notice period described in TSCA section 
14(g)(2)(B) begins on the next business day following the date the 
notice is made available to the submitter in their CDX account.
    (g) Disclosure of Information. After a final determination has been 
made by EPA to release some or all of the information claimed as

confidential, the claim must be asserted and substantiated in 
accordance with the requirements described in 40 CFR part 703 and must 
be submitted via EPA Form 7710-56. If the submitter wants the chemical 
identity to be listed on the confidential portion of the TSCA 
Inventory, the chemical identity must be claimed as confidential and 
the submitter must also follow the

[[Page 29101]]

certification, substantiation, and generic name requirements described 
part 703 and paragraphs (e) and (f) of this section. Otherwise, EPA 
will list the specific chemical identity on the public TSCA Inventory. 
Submitters who did not claim the chemical identity, submitter identity, 
or other information to be confidential in the PMN cannot claim this 
information as confidential in the notice of commencement.
* * * * *
    (e) Confidentiality. (1) Any person who asserts a confidentiality 
claim for chemical identity in a Notice of Commencement submitted under 
Sec.  720.102 must:
    (i) Comply with generic name requirements described in part 703 and 
as specified in paragraph (f) of this section.
    (ii) Agree that EPA may disclose to a person with a bona fide 
intent to manufacture or import the chemical substance the fact that 
the particular chemical substance is included on the confidential TSCA 
Inventory for purposes of notification under section 5(a)(1)(A) of the 
Act.
    (iii) Have available for the particular chemical substance, and 
agree to furnish to EPA upon request:
    (A) An elemental analysis.
    (B) Either an X-ray diffraction pattern (for inorganic substances), 
a mass spectrum (for most other substances), or an infrared spectrum of 
the particular chemical substance, or if such data do not resolve 
uncertainties with respect to the identity of the chemical substance, 
additional or alternative spectra or other data to identify the 
chemical substance.
    (2) Claims of confidentiality must be made in accordance with the 
procedures described in 40 CFR part 703.
    (f) Generic Name. If a submitter asserts a claim of confidentiality 
for chemical identity in a notice of commencement, they must provide a 
structurally descriptive generic name.
    (1) Generic names must:
    (i) Be structurally descriptive (e.g., not a trade name);
    (ii) Describe the chemical structure of the chemical substance as 
specifically as practicable while protecting only those features of the 
chemical structure that are claimed as confidential and disclosure of 
which would likely cause substantial harm to the competitive position 
of the person--the generic name should generally only obscure one 
structural feature, but in any case, should conceal only the feature(s) 
necessary to avoid a likelihood of substantial competitive harm to the 
submitter; and
    (iii) Be consistent with guidance on the determination of 
structurally descriptive generic names, developed in accordance with 
TSCA section 14(c)(4)(A) (e.g., Guidance for Creating Generic Names for 
Confidential Chemical Substance Identity Reporting under TSCA; 
available at https://www.epa.gov/tsca-inventory/guidance-creating-generic-names-confidential-chemical-substance-identity-reporting).
    (2) Generic names will be reviewed by EPA at the time of 
submission. (i) If EPA concludes that a proposed generic name meets the 
criteria in paragraph (f)(1) of this section, EPA will include that 
generic name in the public TSCA Inventory listing for that substance.
    (ii) If the proposed generic name does not meet the criteria in 
paragraph (f)(1) of this section, EPA will notify the submitter 
concerning the deficiency via CDX, as described in 40 CFR 703.5(f). EPA 
will provide 10 business days to correct the deficiency and provide an 
alternative generic name that would be acceptable to EPA. If the 
alternative generic name proposed by EPA is acceptable to the submitter 
(or if the submitter does not respond within the 10-day period), EPA 
will place that alternative generic name on the public TSCA Inventory. 
If the alternative generic name proposed by EPA is not acceptable to 
the submitter, the submitter must submit a revised generic name that 
meets the criteria in paragraph (f)(1) of this section and an 
explanation of how EPA's proposed generic name reveals confidential 
information. If EPA concludes that the submitter's revised generic name 
also does not meet the criteria in paragraph (f)(1) of this section, 
EPA will hold the notice of commencement for a period of up to 10 
business days. Reporting requirements will not be considered to have 
been met and the substance will not be added to the TSCA Inventory 
during this period. If the submission remains deficient after this 10-
day period, EPA will proceed with CBI review of the chemical identity 
claim and will likely deny the claim.

Sec.  725.80  General provisions.

    Claims of confidentiality must be made in accordance with the 
procedures described in 40 CFR part 703, except as modified in this 
paragraph. In general, references to ``chemical'' or ``chemical 
identity'' in part 703 are equivalent to ``microorganism'' or 
``microorganism identity'' for the purposes of this part.
    (a) In place of Sec.  703.5(b)(3)(v), the following question 
applies: Has EPA, another Federal agency, or court made any 
confidentiality determination regarding information associated with 
this microorganism? 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 determination.
    (b) In place of Sec.  703.5(b)(4), the following questions apply:
    (1) Has the identity of the microorganism been kept confidential to 
the extent that competitors do not know it is being manufactured or 
imported

[[Page 29102]]

into US commerce? If not, explain why the microorganism identity should 
still be afforded confidential status (e.g., the microorganism 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 microorganism in the United States is 
publicly available).
    (2) Does the microorganism leave the site of production or testing 
in a form which is accessible to the public or to competitors? If yes, 
please explain what measures have been taken to guard against the 
discovery of its identity. Further, what is the cost to a competitor, 
in time and money, to develop appropriate use conditions? What factors 
facilitate or impede product analysis?

32. Amend Sec.  725.190 by revising paragraph (c) and adding paragraphs 
(e) and (f) to read as follows:


Sec.  725.190  Notice of Commencement of manufacture or import.

* * * * *
    (c) Information to be reported. The NOC must contain the following 
information: Specific microorganism identity, MCAN number, and the date 
when manufacture or import commences. If the person claims any 
information on the form as confidential, the claim must be asserted and 
substantiated in accordance with the requirements described in part 703 
and Sec.  725.80, as indicated in EPA Form 7710-56. If the submitter 
wants the microorganism identity to be listed on the confidential 
portion of the TSCA Inventory, the microorganism identity must be 
claimed as confidential and also follow the certification, 
substantiation, and generic name requirements described in part 703 and 
paragraph (e) and (f) of this section.
* * * * *
    (e) Requirements for assertion. Any person who asserts a 
confidentiality claim for microorganism identity must:
    (i) Comply with the requirements of paragraph (f) of this section 
regarding submission of a generic name.
    (ii) Agree that EPA may disclose to a person with a bona fide 
intent to manufacture or import the microorganism the fact that the 
particular microorganism is included on the confidential TSCA Inventory 
for purposes of notification under section 5(a)(1)(A) of the Act.
    (iii) Have available and agree to furnish to EPA upon request the 
taxonomic designations and supplemental information required by Sec.  
725.12.
    (iv) Make claims of confidentiality in accordance with the 
procedures described in 40 CFR part 703.
    (f) Generic Name. If a submitter asserts a claim of confidentiality 
for microorganism identity in a notice of commencement, they must 
provide a generic name.
    (1) Generic names must:
    (i) Be structurally descriptive (e.g., not a trade name); and
    (ii) Be consistent with guidance on the determination of 
structurally descriptive generic names, developed in accordance with 
TSCA section 14(c)(4)(A) (e.g., Guidance for Creating Generic Names for 
Confidential Chemical Substance Identity Reporting under TSCA). Generic 
names for microorganisms may only mask the portion of microorganism 
identity that the submitter believes is proprietary (considering that 
the identity of a microorganism to be listed on the TSCA Inventory must 
include taxonomic designations (genus, species, and strain), key 
phenotypic traits, key genotypic traits and modifications, genetic 
material that has been introduced or modified, any vector constructs 
used, cellular location of introduced or modified genes, number and 
type of genes introduced or modified, and method of construction or 
modification). Taxonomic designation (in most cases down to strain) 
must be included in the generic name except where the submitter claims 
the taxonomic designation confidential, in which case the person making 
such claim must provide an explanation of why such masking is necessary 
to protect proprietary information. Additionally, the generic 
microorganism identity must include a statement regarding the function 
and stability of the genetic construct. This includes an indication of 
whether the introduced or modified genes are present on the chromosome 
or extrachromosomal.
    (2) Generic names will be reviewed by EPA at the time of 
submission.
    (i) If EPA concludes that a proposed generic name meets the 
criteria in paragraph (f)(1) of this section, EPA will include that 
generic name in the public TSCA Inventory listing for that substance.
    (ii) If the proposed generic name does not meet the criteria in 
paragraph (f)(1) of this section, EPA will notify the submitter 
concerning the deficiency via CDX, as described in Sec.  703.5(h). EPA 
will provide ten business days to correct the deficiency and provide an 
alternative generic name that would be acceptable to EPA. If the 
alternative generic name proposed by EPA is acceptable to the submitter 
(or if the submitter does not respond within the ten-day period), EPA 
will place that alternative generic name on the public TSCA Inventory. 
If the alternative generic name proposed by EPA is not acceptable to 
the submitter, the submitter must submit a revised generic name that 
meets the criteria in paragraph (f)(1) of this section and an 
explanation of how EPA's proposed generic name reveals confidential 
information. If EPA concludes that the revised generic name also does 
not meet the criteria in paragraph (f)(1) of this section, EPA will 
hold the notice of commencement for a period of up to 10 business days. 
Reporting requirements will not be considered to have been met and the 
microorganism will not be added to the TSCA Inventory during this 
period. If the submission remains deficient after this 10-day period, 
EPA will proceed with CBI review of the microorganism identity claim 
and will likely deny the claim.
