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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is finalizing 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 finalizes 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 rule also 
addresses EPA procedures for reviewing and communicating with TSCA 
submitters about confidentiality claims.

DATES: This final rule is effective on August 7, 2023.

ADDRESSES: The docket for this action, identified under docket 
identification (ID) number EPA-HQ-OPPT-2021-0419, is available online 
at https://www.regulations.gov or in person at the Office of Pollution 
Prevention and Toxics Docket (OPPT Docket) in the Environmental

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?

    The statutory authority for this action is provided by section 14 
of TSCA, as amended (15 U.S.C. 2601 et seq.). 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. Section 14 includes 
provisions that explicitly contemplate promulgation of implementation 
rules by the Administrator. For example, 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 such rules regarding a claim for protection from 
disclosure as the Administrator has promulgated or may promulgate 
pursuant to this title.'' In addition, TSCA section 14(c)(3) requires 
that confidentiality claims be substantiated ``in accordance with such 
rules as the Administrator has promulgated or may promulgate pursuant 
to this section.'' Other provisions in TSCA section 14 further 
recognize the role of the Administrator in specifying the form and 
manner in which the requirements of TSCA section 14 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 additional 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 finalizing 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 (hereafter ``the Lautenberg amendments''), 
made significant amendments to TSCA, including new provisions governing 
the assertion and review of CBI claims that EPA is implementing in this 
action.
    In this document, EPA is finalizing specific 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 has authority to require under TSCA but was 
originally submitted via other means; and (5) maintenance and 
withdrawal of confidentiality claims.
    EPA is also finalizing specific 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 finalizing new provisions, as well as amending and 
reorganizing

[[Page 37156]]

existing provisions concerning assertion of confidentiality claims 
under TSCA. Regulatory provisions concerning TSCA CBI claims are 
currently spread over several 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 40 CFR 
contain their own provisions regarding CBI, such as in 40 CFR part 711 
(Chemical Data Reporting) and 40 CFR part 720 (Premanufacture 
Notification).
    In this final rule, most procedural requirements for asserting and 
maintaining confidentiality claims are organized in a new part of 40 
CFR, i.e., in part 703. The provisions in 40 CFR part 703 will apply to 
any TSCA submission, except as modified elsewhere by more specific 
provisions in 40 CFR part 2 or other TSCA-specific regulations in Title 
40 of the CFR.

D. What are the estimated incremental economic impacts of this action?

    EPA has evaluated the potential incremental impacts of this 
rulemaking, including alternative options. The details are presented in 
the economic analysis prepared for the rule (Ref. 2), which is 
available in the docket and is briefly summarized here. The benefits of 
the 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 rule is expected to 
decrease the frequency of submitter error and increase efficiency in 
the processes for asserting and maintaining CBI claims. Lastly, the 
rule will 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 
$272,804 in the first year after the rule is finalized and an annual, 
ongoing burden of approximately 523 hours with an associated cost of 
approximately $45,529 in each following year.

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 before the end of that 10-
year period.
    Several new requirements also apply to EPA, including requirements 
in TSCA section 14(g) to review and approve or deny all chemical 
identity CBI claims asserted since the Lautenberg amendments were 
enacted concerning substances that are or have been offered for 
commercial distribution, as well as a subset of all other 
confidentiality claims. Such reviews must be completed within 90 days 
of assertion of the claim. Under TSCA sections 8 and 14, EPA must also 
review all confidentiality claims for the chemical identity of 
substances listed as active on the TSCA Inventory and assign and apply 
unique identifiers (UIDs) to substances with approved confidentiality 
claims for chemical identity. The amendments to TSCA section 14 also 
expanded the categories of people who may now access TSCA CBI. These 
new provisions have been discussed in previous documents published in 
the Federal Register (see e.g., Refs. 3, 4, and 5).
    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). The final rule includes 
provisions intended to implement many of the new requirements in TSCA 
section 14 for the remaining TSCA regulations, especially requirements 
for asserting a CBI claim and procedures for EPA review of such claims. 
Further background information and a detailed explanation of the 
proposed rule is included in the preamble to the proposed rule (Ref. 
6).

III. Summary of Response to Public Comments

    In response to the proposed rule, EPA received eighteen public 
comments. The commenters include trade associations, non-governmental 
organizations, consultants, and individuals (two anonymous). Major 
comments are discussed in the context of particular provisions in Unit 
IV. A more detailed discussion is available in the Response to Comment 
Document for this rule, which is available in the docket (Ref. 8).

IV. Summary of the Final Rule

A. Existing Regulations Governing Confidentiality Under TSCA

    The final rule centralizes most CBI-related procedures in a new 
part of the TSCA regulations, 40 CFR part 703. This new part also 
largely replaces TSCA-specific CBI regulations in 40 CFR 2.306, though 
a few provisions do remain regarding, e.g., the applicability of the 
Agency's public information rules to TSCA CBI in general and procedures 
for disclosure of information under special circumstances described in 
TSCA sections 14(d)(2) through (7). Section 2.306 has been updated in 
some provisions to conform to the timeframes specified for notice under 
TSCA section 14(g).
    In some cases, such as the regulations implementing TSCA section 
14(d)(2) and (7), the final rule retains a notice requirement that is 
not required by TSCA but which has historically been a feature of EPA's 
40 CFR part 2, subpart B, regulations. EPA received some comments about 
the proposal to retain these notice requirements in the rules, but 
notes that TSCA does not prohibit providing such notice and that 
especially in the case of rarely used disclosure provisions, providing 
notice to the person who asserted the CBI claim does not tend to 
significantly increase Agency burden or diminish the public 
availability of information. Providing notice would also tend to reduce 
confusion for the person who asserted the CBI claim and reduce the 
possibility of unnecessary conflict over the handling of the 
information.

B. Purpose and Applicability

    EPA has somewhat revised 40 CFR 703.1 in response to public comment 
but retains the proposed provisions concerning the scope of information 
that is considered ``reported to or otherwise obtained by EPA pursuant 
to TSCA or its implementing regulations,'' particularly that data need 
not have been submitted pursuant to an exercise of TSCA authority in 
order for it to be considered obtained under TSCA.
    Some commenters criticized the scope provisions as greatly 
expanding the range of information considered submitted under TSCA, 
while others criticized the proposal as greatly narrowing this range. 
EPA responds to both groups of commenters that the proposal was not 
intended to modify the scope of TSCA jurisdiction, but rather to 
clarify it. EPA also notes that the provision regarding what is 
considered obtained under TSCA in the final rule works in tandem with 
the retention of disclosure limits (for reasons other than

[[Page 37157]]

business confidentiality) in the statute under which the information 
was originally provided to EPA.
    EPA has modified the proposed regulation text in response to some 
of these comments. The final rule clarifies and reconciles the 
applicable provisions of TSCA and the other laws by which EPA may have 
received data that is later used for TSCA purposes. Even where TSCA 
excludes certain data from eligibility for business confidentiality 
protection, there are very limited circumstances where the statute 
requires affirmative disclosure of that same data by EPA. Instead, data 
used under TSCA might have originally been submitted under and remain 
protected or restricted from disclosure for reasons other than business 
confidentiality under another statute. An example is FIFRA section 
10(g), which limits disclosure of certain pesticide data to persons who 
can certify they are not acting on behalf of an entity engaged in the 
production, sale, or distribution of pesticides in countries other than 
the United States. Where certain data is not entitled to business 
confidentiality protections under TSCA but does enjoy disclosure 
protections under another statute for other reasons (e.g., FIFRA 
section 10(g)), EPA does not believe there is a conflict between the 
two statutory provisions. It therefore does not violate TSCA for EPA to 
withhold or restrict disclosure of such data pursuant to the 
requirements of the other law. EPA has therefore replaced the proposed 
language concerning resolution of conflicts with language clarifying 
that information that was originally submitted under a statute other 
than TSCA may be protected from disclosure under the provisions of the 
other statute for reasons other than claims of business 
confidentiality, even if the information is subsequently used under 
TSCA and would not be eligible for business confidentiality protections 
under TSCA.
    Related to these provisions, some commenters were concerned that 
data originally obtained under other statutes would be used and 
potentially disclosed to the public by EPA without any notice to the 
original submitter. Particularly with respect to disclosure, this is 
not the case. Such data, once it is considered as being submitted or 
obtained under TSCA, will be treated and disclosed consistent with 
today's final rule, TSCA, and any other pertinent laws. For example, if 
the information were claimed as business confidential and became 
subject to a Freedom of Information Act (FOIA) request or EPA otherwise 
believed that the information might not be entitled to confidential 
treatment, the Agency would review and make a final confidentiality 
determination under TSCA section 14(f), which would involve notice and 
opportunity for affected persons to substantiate confidentiality 
claims--if EPA denies the confidentiality claim, the affected persons 
would be provided notice according to today's final rule and TSCA 
section 14(g).

C. Definitions

    EPA received several comments concerning the proposed definition of 
``health and safety study'' at 40 CFR 703.3, particularly the proposed 
excluded categories of information. Some commenters proposed additional 
exclusions, while others argued that there should be fewer or no 
exclusions because having any exclusions is inconsistent with TSCA and/
or that the proposed categories are information underlying and relevant 
to the studies.
    In this final rule, EPA is declining to add exclusions beyond those 
originally proposed but is making modifications to the original 
proposal to combine similar exclusions and to clarify the intended 
scope of the exclusions. As EPA explained in the preamble to the 
proposed rule (Ref. 6), EPA considers some types of information that 
may be included in or with a study document as not part of the ``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 is it relevant to 
the study results.
    EPA notes that most of the exclusions have long been part of the 
existing TSCA rules in one form or other, such as in 40 CFR parts 720 
and 716, so the final rule will in most respects maintain the status 
quo. EPA also considered TSCA section 14(b)(1) (``[i]nformation 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'') in 
finalizing the list, reasoning that the excluded types of information 
may be protected from disclosure under TSCA section 14 although 
included in a document that also contains information that is not 
protected from disclosure. EPA notes that study reports can and often 
are provided in a number of formats, with variable detail, and with 
varying levels and types of information that are ancillary to the study 
report.
    EPA is declining to add additional exclusions, as many of the 
suggestions made were either redundant with the proposed list (e.g., 
laboratory address is redundant with the name of the laboratory), or do 
not constitute information that EPA can categorically determine as 
unnecessary to interpret the study, and therefore cannot be 
categorically excluded from the definition of a health and safety study 
under TSCA section 3(8).
    The final rule is modified from the proposal to combine similar 
exclusions and to clarify the intended scope of the exclusion. The 
exclusion for name of the submitting company (previously included in 40 
CFR parts 716 and 720) is combined with the exclusion for name of 
laboratory. This exclusion is intended to permit confidentiality claims 
for submitting company identity and other information that would 
disclose company identity, such as addresses and laboratory name in the 
case that the laboratory that conducted the study was part of or 
closely related to the submitting company. The exclusion for ``internal 
product codes'' is clarified with a parenthetical that explains that 
this refers to the code names for a test substance that is used 
internally by the submitting company or is used to identify the test 
substance by the test laboratory. The exclusions for names of 
laboratory personnel and for names and other private information of 
study subjects are also combined in the final rule. Finally, the 
proposed exceptions for costs and other financial data and for product 
development, advertising, and marketing plans are combined. These types 
of information do not often appear in study reports themselves but may 
be included with a larger submission that includes a study report or 
other health and safety data or included in materials relating to cost

[[Page 37158]]

sharing for chemical testing (e.g., in relation to a test order).

D. 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. The final rule retains most of the proposed 
provisions, with some modifications to clarify the regulatory 
provisions, or in response to public comment.
1. Assertion of Confidentiality Claim Upon Submission of Information to 
EPA
    The final rule requires that confidentiality claims be asserted 
(and substantiated as necessary) at the time of submission (limited 
exceptions may apply in the case that such information is collected 
during an in-person TSCA enforcement inspection). See 40 CFR 703.5. 
This includes confidentiality claims for specific chemical identity, 
which must be asserted as specified in existing reporting rules (e.g., 
CDR, 40 CFR part 711). Several commenters expressed concern regarding 
language in the preamble to the proposed rule clarifying that failing 
to assert a CBI claim for a specific chemical identity submitted under 
those existing regulations would lead to the specific chemical identity 
being moved from the confidential to the public portion of the 
Inventory. (Refs. 6 and 8.) The commenters' concern pertains to those 
instances where the chemical identity is reported by accession number 
(a non-confidential identifier) and no chemical identity CBI claim is 
asserted, with the result that the specific chemical identity is moved 
to the public Inventory. Existing rules require that the reporter 
assert and substantiate confidentiality claims for the specific 
identity if they wish for that substance to remain on the confidential 
portion of the TSCA Inventory. See, e.g., 40 CFR 711.20(e). Commenters 
expressed concerns that downstream customers or processors of a 
specific chemical would report under TSCA by accession number and, 
ignorant of specific chemical identity, could accidentally or 
intentionally waive the confidentiality claim and cause the substance 
to lose confidential status.
    EPA has consistently maintained and provided public notice of its 
position that if any submitting entity chooses not to assert and/or 
substantiate a confidentiality claim for a chemical identity as 
required by TSCA section 14, the chemical identity is no longer 
entitled to confidential treatment and may be published on the public 
portion of the TSCA Inventory. For example, the Agency noted in the 
2009 updates of the TSCA Inventory that ``some manufacturers of these 
530 chemical substances did not include any claim of confidentiality 
for the chemical identity of the chemical substance with the IUR 
submission.'' (74 FR 37224 (July 28, 2009) (FRL-8392-4)) (emphasis 
added). See also TSCA Inventory Update Reporting Modifications; 
Chemical Reporting, (76 FR 50815 and 50825 (Sept. 15, 2011) (FRL 8872-
9)) (stating that failure to identify the chemical identity as CBI and 
complete upfront substantiation will waive any CBI claim to the 
chemical identity). This position was further reinforced recently in 
the 2020 Procedures for Review of Confidential Business Information 
Claims for the Identity of Chemicals on TSCA Inventory's Response to 
Comments (RTC) where EPA stated ``[i]f another person reveals to the 
public that a confidential chemical substance is manufactured or 
processed for nonexempt commercial purposes in the United States, then 
the specific chemical identity would no longer be eligible for 
confidential protection, and CBI claims for that specific chemical 
identity would be denied upon review'' (Ref. 10, at 17.)
    EPA has considered the commenters' concerns that an entity lacking 
knowledge of a specific chemical identity may nonetheless waive 
confidentiality for that chemical identity. Such a situation might 
arise when TSCA reporting rules implicate a universe of reporters from 
sectors that typically have little knowledge of the identities of 
specific chemical substances in their products, one example being 
importers of articles containing the chemical substance in question. 
The Agency recognizes that this issue might arise in specific contexts. 
However, this final rule addresses a wide variety of situations where 
the knowledge issue is not presented. EPA believes that the best way to 
address commenters' concerns is to include measures in specific TSCA 
reporting rules that take into account the reporting entity's potential 
lack of knowledge, where such measures are necessary. Addressing the 
issue in the context of specific reporting rules will allow EPA to take 
into consideration the unique reporting context for the rule, such as 
the attributes of specific reporters. For example, a specific reporting 
rule might except all or a category of reporters from requirements to 
reassert chemical identity claims to maintain confidential Inventory 
status.
    Outside this final rule, the Agency has already begun exploring 
options for addressing the knowledge concerns raised by the commenters. 
For example, in the proposed rule TSCA section 8(a)(7) Reporting and 
Recordkeeping Requirements for the Perfluoroalkyl and Polyfluoralkyl 
(PFAS) Substances; Notice of Data Availability and Request for Comment, 
the Agency sought to clarify and add language to the PFAS proposed rule 
based in part on comments received during the public comment period for 
today's final rule and concerning an entity's knowledge of a specific 
chemical identity (Ref. 11).
2. Substantiation and Exemptions
    The final rule includes substantiation questions in 40 CFR 703.5(b) 
largely as set out in the proposed rule. As suggested in the proposed 
rule, the final rule omits a patent-specific question in favor of 
including the issue of patents in another question. The provisions 
concerning substantiation exemptions are as proposed.
    a. Patents. The final rule omits a substantiation question 
exclusively concerned with patents, for the reasons discussed in the 
proposed rule and supported by public comment. Instead, where 
information claimed as confidential appears in some form in a patent or 
patent application, persons submitting those claims must address this 
public disclosure in their answer to the question on public disclosures 
more generally, 40 CFR 703.5(b)(3)(iii). Failure to address such a 
patent disclosure in the substantiation increases the risk that EPA 
will determine the information not entitled to confidential treatment. 
Further discussion of comments concerning CBI and patents is included 
in the Response to Comments for this rule (Ref. 8).
    b. Trade secrets. Consistent with the proposed rule, the final rule 
omits a substantiation question specifically concerning trade secrets. 
See discussion in the preamble to the proposed rule (Ref. 6).
    c. Specificity of competitive harm. EPA received several comments 
on the substantiation question concerning substantial competitive harm 
(40 CFR 703.5(b)(3)(i)), several supporting the proposed question, some 
advocating instead for a version of the question currently used for CDR 
submissions (40 CFR 711.30; ``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

[[Page 37159]]

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''), or clarification, 
elaboration, or other changes from the proposed question. The final 
rule uses the proposed version of the question. Submitters may continue 
to use existing guidance describing EPA's expectations for 
substantiation and may contact EPA regarding case-specific 
substantiation questions. Guidance and current staff contact 
information is available at https://www.epa.gov/tsca-cbi.
    d. Exemptions. The final rule provisions at 40 CFR 703.5(b)(5) 
concerning substantiation exemptions in TSCA section 14(c)(2) are the 
same as proposed. EPA received limited comment concerning the exemption 
at TSCA section 14(c)(2)(G), for the specific identity of chemicals 
that have not yet been introduced into commerce, arguing that because 
the exemption may only be applied to claims made up until the substance 
is introduced into commerce, EPA has an obligation to revisit those 
pre-commerce claims once the substance has been introduced into 
commerce. While EPA agrees that new claims for the same information 
would no longer be exempt from the substantiation requirement once the 
chemical is introduced into commerce, there is nothing in the statute 
to suggest that EPA is required to revisit those prior claims. Indeed, 
CBI claims are generally only reviewed as required by TSCA section 
14(g) (within 90 days of submission) or as permitted or required 
pursuant to one of the provisions of TSCA section 14(f). The filing of 
a Notice of Commencement (NOC), for example, does not trigger a 
mandatory review of prior CBI claims for the subject chemical substance 
by the same submitter.
3. Public Copies of Submissions
    40 CFR 703.5(c) of the final rule includes a requirement that TSCA 
submitters include a public copy (sometimes referred to as a 
``sanitized copy'') of their submission, though 40 CFR 703.5(c)(1) 
limits this requirement to unfielded data, such as study reports and 
other documents that might be submitted as attachments to a reporting 
form. Most TSCA submissions that are made on a standard reporting form 
include individual data fields that each have a checkbox-type indicator 
for confidentiality claims. In the case of these forms, a public copy 
is either already generated automatically, or the reporting tool could 
be updated to perform this function in future enhancements of CDX. 
Commenters generally supported this provision in the proposal, though 
some argued that EPA should further elaborate in the rule on how and 
when public copies would be made available, or that EPA should reject 
entire submissions or disregard CBI claims in submissions with 
incomplete or possibly incomplete public copies. The Response to 
Comments document (Ref. 8) elaborates on EPA's current and planned 
practices for making public copies of TSCA submissions available, while 
noting that committing many of these practices to a rule is beyond the 
intended scope of this rulemaking activity except to the extent EPA 
finds the public copy to be deficient. The final rule provisions 
concerning treatment of deficiencies including missing or incomplete 
public copies are elaborated in Unit IV.D.6.
4. Supporting Statement and Certification
    The final rule at 40 CFR 703.5(a) includes certification and 
supporting statements as set out in TSCA section 14, which are 
consolidated into one certification that is automatically incorporated 
into most TSCA reporting forms. TSCA submitters who for unusual and 
case-specific reasons are not able to provide their submission via CDX 
must assure that the consolidated statement is included in their 
submission. This provision is unchanged from the proposal.
5. Generic Names
    The final rule includes provisions specifying requirements for 
generic chemical names, which are used in place of specific chemical 
names in public documents mentioning substances with confidential 
specific chemical identities. 40 CFR 703.5(d). The requirements cover 
when and how such generic names must be submitted, some basic 
requirements, and procedures for resolving disagreements about the 
adequacy of a given generic name. 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) (Ref. 7).
    The generic name provisions in the final rule are the same as were 
proposed. EPA received a few public comments on these provisions, 
questioning incorporation of elements of EPA's generic name guidance 
into the rule, urging that EPA should undertake a CBI review of every 
generic name submitted under TSCA section 14, and suggesting that 
procedures permitting negotiation of generic names or permitting 
correction of deficiencies that EPA identifies with a generic name are 
too complex or are unnecessary, among other comments.
    EPA concluded that incorporation of elements of the generic name 
guidance into the rule provides helpful clarification concerning 
minimum generic name requirements. Despite that clarification, however, 
EPA's experience is that, in some instances, disagreement regarding the 
sufficiency of a generic name may be unavoidable. Therefore, the final 
rule sets forth a streamlined process for negotiating generic names in 
TSCA section 5 Notices of Commencement (40 CFR 720.102) and introduces 
a provision for EPA to provide an opportunity to correct deficient 
generic names in any TSCA submission (40 CFR 703.5(e)). The 
substantiation exemption for certain specific chemical identities 
contained in section 14(c)(2)(G) and corresponding exclusions from 
routine CBI review under TSCA section 14(g) indicate that substantive 
review of the sufficiency of every generic name at the time of 
submission is both in excess of TSCA requirements and impractical 
(especially where the substantiation necessary to complete such a 
review is neither required nor provided). The Response to Comments 
document provides more detailed discussion of these comments. (Ref. 8.)
6. Deficient Submissions
    The clear requirements in the final rule regarding assertion of CBI 
claims, combined with recent improvements to TSCA reporting tools 
including near-universal electronic reporting, should significantly 
reduce the incidence of procedural deficiencies. Nonetheless, EPA does 
not expect that these will prevent all such problems. EPA is therefore 
retaining the proposed deficiency provisions in the final rule at 40 
CFR 703.5(e).
    Some public commenters advocated that the short correction period 
provided in the rule should be longer, and/or that EPA should give one 
or more additional notices, using both electronic and paper means of

[[Page 37160]]

communication. Others criticized providing any such opportunity to 
correct deficiencies, arguing that it would deprive the public of 
information that should be treated as non-confidential and that EPA 
should instead either reject such submissions outright, or immediately 
disclose the information subject to the deficient claim. As elaborated 
in the Response to Comments Document, the time period for correction of 
deficiencies is necessarily quite short, given statutory constraints on 
the time for CBI review and reviews under other parts of TSCA, such as 
TSCA section 5 (Ref. 8). As is also elaborated in the Response to 
Comments Document (Ref. 8) and in Unit IV.D.7. of this document, it is 
now a practical necessity that EPA and TSCA submitters rely primarily 
on electronic communications and notices made through CDX. Id.
    By relying on electronic communications and keeping the period for 
correcting deficiencies short, EPA believes information not entitled to 
confidential treatment will be available to the public more quickly 
using the approach in the final rule (which also briefly pauses other 
statutory review periods, such as under TSCA section 5, such that the 
public is not deprived of the materials for any longer than it takes to 
identify the deficiency) than if EPA instead rejected the whole 
submission or proceeded to immediately release the information 
(actions, especially in the latter case, that could be expected to 
precipitate protracted litigation over an Agency action that could be 
seen as unduly punitive, arbitrary, and beyond statutory authority).
7. Electronic Reporting
    The final rule requires, with very limited exceptions, that all 
TSCA submissions that include CBI claims must be submitted 
electronically. 40 CFR 703.5(f). This requirement most notably affects 
reporting under TSCA section 8(e), export notifications under TSCA 
section 12(b), and polymer exemption notices under TSCA section 5, for 
which electronic reporting is required for the first time in today's 
final rule. Voluntary e-reporting was already available for TSCA 
sections 8(e) and 12(b) notices, so those existing reporting tools will 
be updated in accordance with the final rule and will become mandatory 
to use for reporting. A new reporting tool will be available for 
submitting annual polymer exemption notices. A few commenters expressed 
concern over reliance on electronic reporting, citing past incidences 
of technical difficulties with providing electronic submissions via 
CDX, especially related to 2020 CDR reporting (Ref. 8). EPA notes that 
in the case of 2020 CDR reporting, EPA moved quickly to correct the 
technical problems and extended the reporting deadline to accommodate 
reporters who had issues. Similar problems, many of which were related 
to both the large size of individual submissions and the peak volume of 
submissions being made around the same time, are fairly unique to the 
CDR rule reporting and would not be expected with TSCA section 8(e), 
TSCA section 12(b), or polymer exemption reporting, as the former two 
submission types are submitted throughout the year (not all at once) 
and for all three submission types, most submissions are fairly small. 
EPA expects that in the case technical reporting issues such as 
occasionally encountered in the 2020 CDR reporting period do recur in 
the future, the Agency would continue its practice of promptly 
addressing the problem and making appropriate accommodations (such as 
extending reporting deadlines). Also, noting one comment concerned with 
potential legal barriers to electronic reporting, such as when a 
submission might include classified information or otherwise include 
handling restrictions distinct from CBI claims, EPA expects to continue 
to handle these unusual and rare situations on a case-by-case basis, in 
accordance with their special legal and technical needs.
8. Requirement To Report Health and Safety Information Using OECD 
Harmonized Templates
    EPA is finalizing the requirement to provide health and safety 
information using the appropriate OECD harmonized template (OHT), when 
such a template is available. 40 CFR 703.5(g). As explained in the 
preamble to the proposed rule, this requirement would be in addition to 
existing requirements to provide a full study report. EPA received some 
non-specific comments suggesting that the reporting burden associated 
with filling in such templates would be more substantial than EPA 
estimated, but these comments provided no alternative estimate. Use of 
the templates is already required for submitting data to regulatory 
authorities in other countries (e.g., to the European Chemicals Agency 
(ECHA)) and international programs with strong U.S. participation and 
support encourage and facilitate reciprocal acceptance and use of data 
and non-duplication of chemical safety testing (see, e.g., the OECD 
Mutual Acceptance of Data (MAD) system, https://www.oecd.org/env/ehs/mutualacceptanceofdatamad.htm). Thus, in many if not most cases, 
companies or groups of companies conducting and/or submitting such 
chemical safety testing in the U.S will have already or would otherwise 
be required to fill out such templates anyway when providing the same 
information to regulatory authorities in other countries. Templated 
data will make CBI review of the submission more efficient (by aiding 
in identification of CBI claims) and aid in data sharing and 
dissemination within EPA and in public databases. EPA intends to 
elaborate on instructions for including OHT files (e.g., currently 
acceptable file types and IUCLID software versions) as appropriate in 
individual reporting rules or orders, and/or in the applicable 
reporting tool instruction documents.
9. Maintenance of Company Contact Information and Communications 
Concerning Claims
    The final rule provisions concerning maintenance of company contact 
information and reliance on electronic notices concerning CBI claims 
are as proposed. 40 CFR 703.5(h). EPA received several comments in 
favor of EPA providing redundant multi-media notices (electronic, paper 
mail, email, etc.) and concerned with the burden of maintaining contact 
information for each submission over time. As explained in the preamble 
to the proposed rule, it is EPA's experience that providing notice by 
other permissible means, such as via certified mail, does not 
necessarily better assure prompt delivery and access by its intended 
recipient than would EPA's proposed and preferred shift to reliance on 
electronic notices. For those commenters who advocated an email in 
addition to a CDX-delivered electronic notice, EPA notes that this is 
already occuring--each CDX notice coincides with a more generic email 
notice to the email address provided by the company contact.
    Maintaining contact information for individual submissions is an 
inescapable consequence of the Lautenberg amendments, particularly 
since most CBI claims now expire after ten years unless reasserted by 
the submitter. The TSCA section 14(f) CBI review provisions also call 
for submission-specific company contact maintenance, in that those 
types of CBI review almost always require some notice to the company, 
both that the review is taking place and for the purpose of permitting 
submission of substantiation. Such reviews can take place at any time 
after a submission is made. EPA has created new reporting

[[Page 37161]]

tools that permit a company to request copies of record it may have 
lost access to by turnover in personnel or to provide updated contact 
information for one or more company submissions. More broadly, EPA 
strongly suggests that companies develop internal practices to assure 
that a current company contact is maintained for each of their 
submissions including CBI. This might include, for example, use of 
email addresses that more than one person can access to receive CBI 
notices, a limited-access internal list of submission passphrases, or 
other procedures to better assure that passphrases and TSCA submission-
specific information is known to or available to more than one person 
and isn't lost to the company when any one of its personnel are 
suddenly unavailable.
10. Withdrawing Claims
    The final rule adopts the proposed provisions on withdrawing 
claims, which provide instructions for withdrawing claims originally 
made in an electronic submission, and for withdrawing claims originally 
made on paper or in an electronic submission no longer accessible to 
the company. 40 CFR 703.5(i).
11. Amending a Public Copy Following Claim Denial or Expiration
    Public commentary was divided on who should be responsible for 
updating public copies of submissions to make newly non-CBI information 
available (the submitting company or EPA); other commenters suggested 
that making this information available need not be a priority unless a 
specific request for it was pending (e.g., a FOIA request). Based on 
its experience, EPA has concluded that companies submitting CBI claims 
should retain primary responsibility for updating public copies. 
Because the company best understands the intended scope and purpose of 
its original CBI claim(s), that company is in the best position to 
determine with precision which of its claims remain and assure these 
are indicated in the public copy accurately prior to release of the 
data. If EPA must occasionally dispute the scope of the remaining 
claims indicated by the submitter, EPA and the submitter could resolve 
this issue prior to release of the data, which is not possible when EPA 
prepares and releases the updated public copy without the involvement 
of the submitter. The final rule does include some minor amendments to 
clarify how EPA will append public copies to make newly non-CBI 
information available, in cases where EPA must perform this function. 
40 CFR 703.5(j).

E. EPA Review of Confidentiality Claims

1. Representative Subset
    EPA received several comments on selection of the representative 
subset (40 CFR 703.7(a)), especially on the submissions it proposed to 
exclude from the subset as not being especially representative of TSCA 
submissions more generally. The final rule maintains the proposed case 
selection methodology (one in four TSCA submissions with non-exempt CBI 
claims for information other than chemical identity) but clarifies that 
this is the method EPA will use in general. EPA believes that some 
flexibility is appropriate here in case it might occasionally be 
necessary to issue additional confidentiality determinations to ensure 
that the Agency is meeting the minimum 25% required by TSCA section 
14(g)(1)(C)(ii). The final rule also maintains the proposed exclusions 
from the representative subset, including certain pre-submission types 
of correspondence intended mainly to ascertain subsequent TSCA 
reporting obligations (e.g., bona fide notices under 40 CFR 720.25), 
occasional submissions that may be excluded from the otherwise nearly 
universal electronic reporting requirement, and amendments. In general, 
EPA believes that excluding these submissions is appropriate and will 
not significantly affect the total number of claims reviewed because 
these submissions may not contain many claims in the first place, the 
claims they do include are or will be duplicated in other submissions, 
and/or the submission type is relatively rare.
2. Substantive Criteria
    TSCA itself does not specify the criteria that must be used in 
making a confidentiality determination, so EPA proposed and will retain 
in this final rule (40 CFR 703.7(f)) elements drawn from TSCA section 
14(b) limitations of confidentiality protections, TSCA section 14(c) 
requirements to assert confidentiality claims, as well as EPA's long 
pre-existing criteria for evaluation of confidentiality claims as set 
out in 40 CFR 2.208.
    Some commenters suggested a longer list of criteria or somewhat 
different wording to more strongly emphasize some parts of some 
criteria over others. EPA has declined most of these suggestions as EPA 
believes them to be unnecessary and unlikely to influence the outcome 
of a CBI determination. In response to one comment noting that a FOIA-
specific criterion was missing from the proposed 14(g) substantive 
criteria in 703.7 (it was proposed in 703.8 only for FOIA-prompted 
reviews under TSCA section 14(f)), EPA has made the substantive 
criteria uniform for any CBI determination. Though introducing some 
redundancy with the other criteria, EPA believes that one set of 
criteria for all reviews improves clarity and consistency between 
reviews.
    EPA has declined the suggestion of one commenter that the criterion 
mentioning the limited confidentiality protections for health and 
safety study data (40 CFR 703.7(f)(5)) should be expanded to permit 
generic name to stand in for specific identity in any health and safety 
study for which the submitter wishes to assert a CBI claim. Instead, 
the study report would refer only to the generic name of the substance. 
The commenter supposed that simply not including the specific chemical 
identity in the study report could avoid the section 14(b) limitations 
on CBI protections in health and safety data. However, taking the 
commenter's suggestion would be contrary to longstanding EPA policy and 
rules stating that chemical identity is always considered part of a 
study (e.g., 40 CFR 720.3(k)); ignore the fact that health and safety 
studies are usually submitted as part of (attachments to) various TSCA 
reporting forms that also specifically identify the chemical; and not 
reflect the fact that chemical identity may be protected as CBI, need 
not be substantiated, and will not be routinely reviewed (under TSCA 
section 14(g)) until the chemical substance is introduced into U.S. 
commerce. However, the criterion has been clarified in the final rule 
to reflect that the limitations on confidentiality protections don't 
apply to all health and safety information that might be submitted 
under TSCA (e.g., data on R&D substances, prior to premanufacture 
notification).
3. Reconsideration Process
    After considering comment on the proposal, EPA has decided to omit 
the reconsideration process (for denied CBI claims) from the final rule 
(Ref. 6). While some commenters supported the proposal, others did not, 
describing it as biased, open-ended, and lacking in transparency. EPA 
now believes that codifying a reconsideration process is unnecessary. 
If a person believes that a determination was incorrect or has 
questions about the determination, they may contact EPA (using the 
contact information in the final CBI determination letter) about their

[[Page 37162]]

concerns prior to filing a judicial appeal.

F. Related or Corresponding Revisions to Other TSCA Rules

1. Revisions to 40 CFR Parts 702, 704, 707, 716, 717, 723, and 790
    The final rule replaces the CBI provisions of several TSCA rules 
with a cross reference to 40 CFR part 703 to centralize the CBI rules 
and make them more consistent among submission types. EPA received some 
comment advocating for retaining some of the existing CBI provisions, 
but EPA believes this is unnecessary, redundant, and/or needlessly 
inconsistent with the final CBI rules centralized in 40 CFR part 703. 
For further discussion, see the Response to Comments (Ref. 8).
2. Clarification of TSCA Section 12(b) Rules
    The language in 40 CFR part 707 is revised in the final rule to 
cross reference 40 CFR part 703 for CBI reporting requirements, to 
require electronic reporting, and to clarify that it is generally not 
necessary to list confidential specific chemical identities in a TSCA 
section 12(b) report. EPA received some public comment criticizing this 
provision, misunderstanding the clarification as rescinding a previous 
requirement to provide specific chemical identities in TSCA section 
12(b) notices. Part 707 regulations never included such a requirement, 
though some submitters unnecessarily provided such information anyway. 
The Response to Comments Document provides further clarification of the 
pre-existing rule and elaborates on how EPA processes TSCA section 
12(b) notices without need for a confidential specific chemical 
identity in the report (Ref. 8).
3. Revision in 40 CFR 717.17 and 723.250 To Reflect Electronic 
Reporting
    The final rule revises 40 CFR parts 717 and 723 to reflect that 
TSCA section 8(c) incident reports and TSCA section 5 polymer exemption 
notices must be submitted electronically.
4. Revisions to Confidentiality Provisions in the Premanufacture Notice 
(PMN) and Microbial Commercial Activity Notice (MCAN) Rules
    The final rule revises 40 CFR parts 720 and 725 as proposed. Some 
public commenters also favored retaining more of the CBI provisions in 
40 CFR part 720. A commenter asserted that the proposed revisions to 40 
CFR 720.85 omitted necessary existing statements that are not 
sufficiently duplicated in the final rule--EPA disagrees and notes that 
the commenter in some areas misunderstands 40 CFR 720.85. The language 
in 40 CFR part 720.85(a) is mostly redundant with TSCA section 14, 
other provisions of the final rule, or both. Under the final rule, 
persons may assert CBI claims for chemical identity in a PMN, but they 
must also submit a generic name consistent with TSCA section 14(c). 
Persons who would like to consult EPA concerning an appropriate generic 
name may continue to do so through the pre-notice consultation process. 
See: https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca/filing-pre-manufacture-notice-epa#pre-notice.
    Much of 40 CFR 720.85(b) is retained in the final rule, but has 
been moved to 40 CFR 720.102, while the substantiation provisions are 
replaced with the substantiation provisions in 40 CFR part 703. The 
provision in section 720.85(b)(1), providing that a CBI claim for 
chemical identity may not be asserted in an NOC unless that CBI claim 
has been asserted for the underlying PMN, is not necessary. If the 
chemical identity is not claimed as CBI in the PMN, the chemical 
identity is published in the public notice required by TSCA section 
5(d)(2). PMNs and NOCs are identified by the same case number, 
providing a public link between the NOC and the PMN. Upon required TSCA 
section 14(g) review of the chemical identity claim in the NOC, EPA 
would not uphold a confidentiality claim that was not made in the PMN. 
Further discussion is available in the Response to Comments document 
(Ref. 8).
    One commenter advocated retaining most of 40 CFR 720.90 (except 
(a)(3), (b)(2)(iii), and (c)(3)), arguing that chemical identity claims 
should not be permitted in health and safety studies at the PMN stage, 
but that if EPA continues to permit such claims in the PMN, the PMN 
claim should be re-reviewed when an NOC is filed and chemical identity 
should be disclosed. EPA disagrees. Chemical identity claims are 
permitted in the PMN submission including attachments, and such claims 
are exempt from upfront substantiation requirements under TSCA section 
14(c)(2)(G) and from routine review under TSCA section 14(g). TSCA 
section 14(g) requires that EPA review certain CBI claims within 90 
days of submission. In nearly all circumstances, an NOC is filed well 
more than 90 days after the PMN, usually months or sometimes years 
later (or not at all). The NOC is also, while linked to the PMN 
submission, a different TSCA submission--one that does not include 
health and safety studies. NOCs are subject to review under TSCA 
section 14(g), as are PMNs, but the filing of an NOC does not open or 
reopen the TSCA section 14(g) review of the PMN filed previously. 
Instead, the PMN may be reviewed or re-reviewed pursuant to TSCA 
section 14(f), under one of the mandatory or discretionary provisions, 
where applicable. Even following TSCA section 14(f) review, many 
chemical identity claims in health and safety studies will still be 
valid, as TSCA section 14(b) includes exceptions from information that 
is not protected from disclosure, including information that discloses 
processes used in the manufacture of a substance or portion of mixture 
information.

VI. Statutory and Executive Order Reviews

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

A. Executive Orders 12866: Regulatory Planning and Review and 14094: 
Modernizing Regulatory Review

    This action is not a significant regulatory action as defined in 
Executive Order 12866 (58 FR 51735, October 4, 1993), as amended by 
Executive Order 14094 (88 FR 21879, April 11, 2023), and was therefore 
not subject to Executive Order 12866 review.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this final rule have been 
submitted to OMB for approval under the PRA, 44 U.S.C. 3501 et seq. The 
Information Collection Request (ICR) document that EPA prepared is 
assigned EPA ICR No. 2706.02 and OMB Control No. 2070-0223 (Ref. 9). 
You can find a copy of the ICR in the docket for this action, and it is 
briefly summarized here. The information collection requirements are 
not enforceable until OMB approves them.
    The reporting requirements identified in this final rule implement 
statutory requirements in TSCA section 14, including the new 
requirements that persons submitting information under 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 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 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. See also Unit I.A.
    Respondent's obligation to respond: Mandatory (TSCA section 14; 15 
U.S.C. 2613).
    Frequency of response: On occasion.
    Total estimated number of respondents: 1,100 firms with an 
estimated additional 55 new firms each year.
    Total estimated number of responses: 1,100.
    Total estimated burden: 2,945 hours in the first year and 523 hours 
every subsequent year. Burden is defined at 5 CFR 1320.3(b).
    Total estimated cost: $ 272,804 in the first year and $ 45,592 
every subsequent year, which includes $ 0 annualized capital or 
operation and maintenance costs.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the EPA 
regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves 
this ICR, the Agency will announce that approval in the Federal 
Register and publish a technical amendment to 40 CFR part 9 to display 
the OMB control number for the approved information collection 
activities contained in this 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 1,001 small firms would be affected by the proposed 
requirements. Of those small firms, 100% would have cost impacts of 
less than 1 percent of annual revenues, which EPA has determined does 
not qualify as a significant impact. Details of this analysis are 
presented in the Economic Analysis (Ref. 2), which is available in the 
docket. We have therefore concluded that this action will have not have 
a significant adverse economic impact on all directly regulated small 
entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate 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) because 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) because it will 
not have substantial direct effects on Tribal governments, on the 
relationship between the Federal government and the Indian Tribes, or 
on the distribution of power and responsibilities between the Federal 
government and Indian Tribes. It does not have substantial direct 
effects on Tribal government because EPA does not anticipate that 
Tribal governments will often make TSCA submissions, let alone those 
for which they would assert a CBI claim necessitating substantiation 
and other requirements under TSCA and this rule, so this rulemaking is 
not expected to impose substantial direct compliance costs on Tribal 
governments. Thus, Executive Order 13175 does not apply to this action.

[[Page 37164]]

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

    EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) 
as applying only to those regulatory actions that concern environmental 
health or safety risks that the EPA has reason to believe may 
disproportionately affect children, per the definition of ``covered 
regulatory action'' in section 2-202 of Executive Order 13045. This 
action is not subject to Executive Order 13045 because it does not 
concern environmental health risk or safety risk.
    Although this action does not concern human health or safety risk, 
it does set clear procedures for confidentiality claims made by 
reporting entities under TSCA, this action is expected to improve the 
quality of such claims, reduce unnecessary and unsupported claims, and 
is anticipated to result in more information being available to the 
public. This action does not address any human health or environmental 
risks and does not affect the level of protection provided to human 
health or the environment. Information submitted under TSCA can also be 
used by government agencies and others to identify potential problems, 
set priorities, and take appropriate steps to reduce any potential 
risks to human health and the environment and as noted in this 
paragraph, may make more of this information available to the public.

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

    This action is not a subject to Executive Order 13211 (66 FR 28355, 
May 22, 2001) because it is not a significant regulatory action under 
Executive Order 12866 and has not otherwise been designated as a 
significant energy action by the Administrator of the Office of 
Information and Regulatory Affairs.

I. National Technology Transfer and Advancement Act (NTTAA)

    This action does not involve technical standards that would require 
Agency consideration under NTTAA section 12(d), 15 U.S.C. 272.

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

    Executive Order 12898 (59 FR 7629, February 16, 1994) directs 
Federal agencies, to the greatest extent practicable and permitted by 
law, to make environmental justice part of their mission by identifying 
and addressing, as appropriate, disproportionately high and adverse 
human health or environmental effects of their programs, policies, and 
activities on minority populations (people of color and/or indigenous 
peoples) and low-income populations.
    EPA believes that this action does not directly concern human 
health or environmental conditions and therefore cannot reasonably be 
evaluated with respect to potentially disproportionate and adverse 
effects on people of color, low-income populations and/or indigenous 
peoples. This action does not directly address any human health or 
environmental risks and does not directly affect the level of 
protection provided to human health or the environment. However, 
although this action does not directly concern human health or 
environmental conditions, in setting clear procedures for 
confidentiality claims made by reporting entities under TSCA, this 
action is expected to improve the quality of such claims, reduce 
unnecessary and unsupported claims, and is anticipated to result in 
more information being available to the public. By ensuring uniform 
substantiation of CBI claims, electronic reporting requirements, 
certification statements, clarifying how EPA treats certain information 
initially obtained in a context other than TSCA, and the process for 
maintenance or withdrawal of confidentiality claims, EPA is improving 
communications and transparency to the public and promoting consistency 
for the regulated community. Improved communication and transparency 
has inherent informational benefits including increasing understanding 
and awareness of potential issues related to chemical information. 
Information submitted under TSCA can also be used by government 
agencies and others to identify potential problems, set priorities, and 
take appropriate steps to reduce any potential risks to human health 
and the environment and as noted in this paragraph, may make more of 
this information available to the public. Therefore, the informational 
benefits of the action are likely to have a positive impact on the 
human health and environmental impacts of all populations, including 
minority populations, low-income populations, and indigenous peoples.

L. Congressional Review Act (CRA)

    This action is subject to the CRA, 5 U.S.C. 801 et seq., and EPA 
will submit a rule report to each House of the Congress and to the 
Comptroller General of the United States. This action is not a ``major 
rule'' as defined by 5 U.S.C. 804(2).

Administrator.

    Therefore, for the reasons stated in the preamble, 40 CFR chapter I 
is amended as follows:

PART 2--PUBLIC INFORMATION

0
1. The authority citation for part 2 continues to read as follows:

    Authority:  15 U.S.C 2613.

0
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:
    Act means the Toxic Substances Control Act, 15 U.S.C. 2601 et seq.
    Chemical substance has the meaning given it in section 3(2) of the 
Act, 15 U.S.C. 2602(2).
    EPA Legal Office means the EPA Office of General Counsel and any 
EPA office over which the EPA General Counsel exercises supervisory 
authority.
    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 of this part apply without change to 
information to which this section applies. Unless otherwise specified 
in this section, 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. (1) EPA intends to make 
disclosures pursuant to a request under section 14(d)(4), (5), or (6) 
of the Act for information to which this section applies in accordance 
with the requirements of the Act and any applicable EPA guidance 
required by section 14(c)(4)(B) of the Act.
    (2) Section 2.209 applies to information to which this section 
applies, except that:
    (i) The notification specified in Sec.  2.209(b)(2) is 15 business 
days.
    (ii) The following two additional provisions apply to Sec.  
2.209(c):
    (A) 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
    (B) 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)).
    (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 shall be disclosed by EPA to 
a contractor or subcontractor of the United States if, in the opinion 
of the Administrator, the disclosure 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 
subcontractor of the contract or subcontract.
    (2) The provisions of Sec.  2.301(h)(2)(ii) through (iv) apply to 
disclosures under paragraph this (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(h) of the Act (15 U.S.C. 2613(h)).
    (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 shall be disclosed by EPA if the 
Administrator determines that 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 identified as relevant by the Administrator 
under the 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

[[Page 37166]]

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 requirements in 
TSCA sections 14(b) and (c), to facilitate EPA review of such claims in 
accordance with TSCA sections 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. This includes information that was first obtained by EPA 
other than pursuant to the authority of TSCA or its implementing 
regulations, provided that the following two criteria have been met:
    (1) EPA has authority to collect the information under TSCA; and
    (2) 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 (e.g., EPA considered such information 
in its actions under TSCA sections 4, 5, or 6).
    (c)(1) This part applies regardless of the following:
    (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) However, where such information is not protected from 
disclosure under TSCA Section 14, but the statute under which the 
information was originally provided to EPA limits disclosure for 
reasons other than business confidentiality (for example, limited 
disclosure of pesticide data to multinational pesticide producers under 
7 U.S.C. 136h(g)), the disclosure limitation in the statute under which 
the information was obtained by EPA continues to apply, except where 
TSCA expressly requires disclosure of that information.
    (d) The provisions of 40 CFR part 2, subpart B, apply to this 
section, as modified by 40 CFR 2.306.

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) of 
this subchapter for test data also applies in this part.
    Accept in the context of asserting a TSCA CBI claim means EPA's 
first approval of the submission containing the CBI claim in CISS, or 
its successor system.
    Act, or TSCA, means the Toxic Substances Control Act, 15 U.S.C. 
2601 et seq.
    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.
    FOIA means the Freedom of Information Act, 5 U.S.C. 552, et seq.
    Health and safety study has the same meaning as that provided in 
Sec.  720.3(k) of this subchapter, except that for purposes of this 
part 703 the following information is not part of a health and safety 
study:
    (1) The name, address, or other identifying information for the 
submitting company, including identification of the laboratory that 
conducted the study in cases where the laboratory is part of or closely 
affiliated with the submitting company.
    (2) Internal product codes (i.e., code names for the test substance 
used internally by the submitting company or to identify the test 
substance to the test laboratory).

[[Page 37167]]

    (3) Names and contact details for testing laboratory personnel and 
names and other private information for health and safety study 
participants or persons involved in chemical incidents such as would 
typically be withheld under 5 U.S.C. 552(b)(6) or under other privacy 
laws.
    (4) Information pertaining to test substance product development, 
advertising, or marketing plans, or to cost and other financial data.

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 except where such a claim is disallowed by 
applicable regulation under this subchapter. 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. (1) A person asserting 
a confidentiality claim must submit a statement that the person has:
    (i) Taken reasonable measures to protect the confidentiality of the 
information;
    (ii) Determined that the information is not required to be 
disclosed or otherwise made available to the public under any other 
Federal law;
    (iii) A reasonable basis to conclude that disclosure of the 
information is likely to cause substantial harm to the competitive 
position of the person; and
    (iv) A reasonable basis to believe that the information is not 
readily discoverable through reverse engineering.
    (2) 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) 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 business days after the 
inspection ends. Confidentiality claims lacking required substantiation 
after ten business days will be treated as deficient under paragraph 
(e) of this section. Unless otherwise directed by EPA, such information 
or materials must be submitted via CDX. In the case of an unusually 
voluminous document collection under section 11 of the Act, the 
affected company may request additional time to assert claims and 
provide substantiation, which EPA may grant at its discretion. The 
inspection is considered to have ended when the inspector physically 
exits the regulated facility on the last day of the inspection.
    (2) 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 separately 
substantiated.
    (3) Substantiation questions for all claims. Unless otherwise 
specified elsewhere in this subchapter (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. If this chemical 
is patented and the patent reveals the information you are claiming 
confidential, please explain your reasons for believing the information 
is nonetheless still 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 or not 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 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].

[[Page 37168]]

    (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) Information described in paragraphs (b)(5)(i) and (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 (e) 
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) of this subchapter), 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 
and in the same manner 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) so 
will likely be treated as deficient under paragraph (e) of this 
section.
    (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 treat as deficient 
submissions with public 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, and made binding by, section 14(c)(4)(A) 
of the Act (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 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) of 
this subchapter. In such cases, EPA will notify the submitting company 
and proceed as described in Sec.  720.102(f) or Sec.  725.190(f) of 
this subchapter.
    (4) If EPA concludes that the proposed generic name does not comply 
with 15 U.S.C. 2613(c)(1)(C), EPA will

[[Page 37169]]

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, proceeding 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) TSCA submissions bearing 
confidentiality claims must be submitted via CDX, except where EPA 
directs that information subpoenaed under section 11(c) of the Act or 
materials collected or requested by EPA as part of an inspection under 
section 11(a) of the Act, not be submitted via CDX. Any required TSCA 
submission asserting a CBI claim that does not meet the requirements of 
this paragraph will be deemed incomplete. EPA reserves the ability to 
waive the requirements of this paragraph, at its discretion, where 
compliance is infeasible.
    (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) of 
this subchapter, or according to the terms of a specific order under 
section 5(e) of the Act).
    (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 section 14(e) of 
the Act)), 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 section 14(e) of the Act. 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 
section 14(f) of the Act, 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 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

[[Page 37170]]

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. To withdraw a claim, a 
person must reopen the submission in CDX, remove confidentiality 
markings (e.g., confidential checkmarks or bracketing), revise public 
copies including any attachments to unredact the information no longer 
claimed confidential, and then resubmit 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 paragraph (i) of this section.
    (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, disclosing the information to the 
public.

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

    (a) Representative subset and selection of submissions for review. 
(1) A representative subset consists of at least 25 percent 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 the Act. 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 Sec.  721.11 of this 
subchapter;
    (ii) Submissions or other communication not submitted to EPA via 
CDX; and
    (iii) Amendments to previous TSCA submissions.
    (2) To satisfy its confidentiality claim review obligations under 
section 14(g)(1)(C)(ii) of the Act, EPA will generally review all 
claims (except those exempt from substantiation under section 14(c)(2) 
of the Act) 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 sections 14(c)(2) and 14(g) of the Act), 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)(i) Under section 14(g) of the Act, EPA will review:
    (A) All chemical identity claims asserted in TSCA submissions 
except those that are exempt from substantiation according to section 
14(c)(2)(G) of the Act; and
    (B) a representative subset of other confidentiality claims as 
provided in paragraph (a) of this section.
    (ii) Final determinations will be issued by the General Counsel or 
their designee, which may include personnel outside of the Office of 
General Counsel.
    (2) EPA will review all timely requests for extension of claims 
under section 14(e) of the Act within 30 days of receipt.
    (3) EPA will also review or re-review confidentiality claims under 
certain other circumstances, as set out in section 14(f) of the Act. 
Review under section 14(f) of the Act 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 
section 14(g) of the Act 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 section 26(j) of 
the Act.
    (e) Claim denials and notice period. 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, as described in Sec.  703.5(h). 
The 30-day notice period described in section 14(g)(2)(B) of the Act 
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 section 14 of the Act will be 
approved if all of the following apply:
    (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;
    (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);

[[Page 37171]]

    (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 respecting any chemical that 
has been offered for commercial distribution or for which testing is 
required under section 4 of the Act or notice is required under section 
5 of the Act 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.
    (6) 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)).
    (g) 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) will be evaluated 
using the same criteria as described in paragraph (f) of this section. 
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 where authorized by 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 which 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. The exemptions from 
substantiation requirements contained in section 14(c)(2) of TSCA do 
not apply to confidentiality claims reviewed under this section 703.8, 
even if such exemptions applied when the information was originally 
submitted to EPA.
    (c) Additional substantiation. If necessary, such as where 
substantiation has not previously been provided for confidentiality 
claims under review, or where 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).
    (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 Agency shall make the information available to the 
public (in the absence of a court order prohibiting disclosure) 
whenever:
    (1) The period provided for commencement by a business of an action 
to obtain judicial review of the determination has expired without 
notice to EPA of commencement of such an action; or
    (2) The court, in a timely-commenced action, has denied the 
person's motion for a preliminary injunction, or has otherwise upheld 
the EPA determination.
    (h) Notice relating to public requests for records. Any person 
whose request for release of the information under 5 U.S.C. 552 is 
pending at the time notice is given under paragraph (f) of this section 
shall be furnished notice under 5 U.S.C. 552 either stating the 
circumstances under which the some or all of the information will be 
released or denying the request if all requested information was found 
to be entitled to confidential treatment.

[[Page 37172]]

chemical substance or mixture for which export notice is required under 
Sec.  707.60 in accordance with the following:
    (1)(i) The export notice must be for the first export or intended 
export by an exporter to a particular country in a calendar year when 
the chemical substance or mixture is the subject of an order issued, an 
action that is pending, or relief that has been granted under TSCA 
section 5(f), a rule that has been proposed or promulgated under TSCA 
section 6, or an action that is pending or relief that has been granted 
under TSCA section 7.
    (ii) The export notice must only be for the first export or 
intended export by an exporter to a particular country when the 
chemical substance or mixture is the subject of an order issued, an 
action that is pending, or relief that has been granted under TSCA 
section 5(e), a rule that has been proposed or promulgated under TSCA 
section 5(a)(2), or when the submission of data is required under TSCA 
section 4 or 5(b). Under this paragraph, notice of export to a 
particular country is not required if an exporter previously submitted 
to EPA a notice of export to that country prior to January 16, 2007.
    (2) The export notice must be submitted to EPA within seven days of 
forming the intent to export or on the date of export, whichever is 
earlier. A notice of intent to export must be based on a definite 
contractual obligation, or an equivalent intra-company agreement, to 
export the regulated chemical.
    (b) If the EPA action that prompts the notice is a proposed rule, 
the requirement to submit export notices to EPA shall begin thirty days

* * * * *
    (c) * * *
    (2) If the submitter claims any information on the form 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 certification, substantiation, and 
generic name requirements described 40 CFR 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 
this section must:
    (i) Comply with generic name requirements described in 40 CFR 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

[[Page 37173]]

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.

27. Revise Sec.  725.80 to read as follows:

Sec.  725.80  General provisions for confidentiality claims.

    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) of this subchapter, the 
following question must be answered: 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) of this subchapter, 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 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 
of this subchapter 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 of 
this subchapter and paragraphs (e) and (f) of this section.
* * * * *
    (e) Requirements for assertion. Any person who asserts a 
confidentiality claim for microorganism identity must:
    (1) Comply with the requirements of paragraph (f) of this section 
regarding submission of a generic name.
    (2) 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.
    (3) Have available and agree to furnish to EPA upon request the 
taxonomic designations and supplemental information required by Sec.  
725.12.
    (4) 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 
section 14(c)(4)(A) of the Act (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) of 
this subchapter. 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.
