Significant New Use Rule on Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is finalizing a significant new use rule (SNUR) under 
section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the 
chemical substance identified generically as bimodal mixture consisting 
of multi-walled carbon nanotubes and other classes of carbon nanotubes, 
which was the subject of premanufacture notice (PMN) P-11-482. This 
action requires persons who intend to manufacture (defined by statute 
to include import) or process the chemical substance for a use that is 
designated as a significant new use by this final rule to notify EPA at 
least 90 days before commencing that activity. The required 
notification initiates EPA's evaluation of the intended use within the 
applicable review period. Manufacture and processing for the 
significant new use is unable to commence until EPA has conducted a

[[Page 45991]]

review of the notice, made an appropriate determination on the notice, 
and take such actions as are required with that determination. The 
required notification would provide EPA with the opportunity to 
evaluate the intended use and, if necessary, to prohibit or limit that 
activity before it occurs.

DATES: This final rule is effective November 2, 2017.

ADDRESSES: EPA has established a docket for this action under docket 
identification (ID) number EPA-HQ-OPPT-2016-0207. All documents in the 
docket are listed in the docket index available at http://www.regulations.gov. Although listed in the index, some information is

SUPPLEMENTARY INFORMATION: 

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
process, or use the chemical substance identified generically as 
bimodal mixture consisting of multi-walled carbon nanotubes and other 
classes of carbon nanotubes (PMN P-11-482). 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, but are not limited to:
    Manufacturers (including importers) or processors of the subject 
chemical substance (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries.
    This action may also affect certain entities through pre-existing 
import certification and export notification rules under TSCA. Chemical 
importers are subject to the TSCA section 13 (15 U.S.C. 2612) import 
certification requirements promulgated at 19 CFR 12.118 through 12.127, 
and 19 CFR 127.28. Chemical importers must certify that the shipment of 
the chemical substance complies with all applicable rules and orders 
under TSCA. Importers of chemicals subject to a SNUR must certify their 
compliance with the SNUR requirements. The EPA policy in support of 
import certification appears at 40 CFR part 707, subpart B. In 
addition, any persons who export or intend to export the chemical 
substance that is the subject of a proposed or final SNUR are subject 
to the export notification provisions of TSCA section 12(b) (15 U.S.C. 
2611(b)) (see Sec.  721.20), and must comply with the export 
notification requirements in 40 CFR part 707, subpart D.

II. Background

A. What action is the Agency taking?

    EPA is finalizing a SNUR for the chemical substance identified 
generically as bimodal mixture consisting of multi-walled carbon 
nanotubes and other classes of carbon nanotubes (PMN P-11-482). This 
final action requires persons who intend to manufacture or process the 
chemical substance for an activity that is designated as a significant 
new use by this final rule to notify EPA at least 90 days before 
commencing that activity. In the Federal Register of June 8, 2017 (79 
FR 26644) (FRL-9959-37), EPA proposed a SNUR for this chemical 
substance that was the subject of P-11-482. EPA received no comments to 
the proposed SNUR and is finalizing the SNUR as proposed. See the 
proposed SNUR for details and the basis of the proposed SNUR.

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

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including the four bulleted TSCA section 5(a)(2) 
factors listed in Unit III of this document. Once EPA determines that a 
use of a chemical substance is a significant new use, TSCA section 
5(a)(1)(B) requires persons to submit a significant new use notice 
(SNUN) to EPA at least 90 days before they manufacture, import, or 
process the chemical substance for that use (15 U.S.C. 
2604(a)(1)(B)(i)). TSCA furthermore prohibits such manufacturing or 
processing from commencing until EPA has conducted a review of the 
notice, made an appropriate determination on the notice, and taken such 
actions as are required in association with that determination (15 
U.S.C. 2604(a)(1)(B)(ii)). As described in Unit V., the general SNUR 
provisions are found at 40 CFR part 721, subpart A. Persons who must 
report are described in Sec.  721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to the rule, recordkeeping 
requirements, exemptions to reporting requirements, and applicability 
of the rule to uses occurring before the effective date of the final 
rule. Provisions relating to user fees appear at 40 CFR part 700. 
According to Sec.  721.1(c), persons subject to these SNURs must comply 
with the same SNUN requirements and EPA regulatory procedures as 
submitters of PMNs under TSCA section 5(a)(1)(A). In particular, these 
requirements include the information submission requirements of TSCA 
section 5(b) and 5(d)(1), the exemptions authorized by TSCA section 
5(h)(1), (h)(2), (h)(3), and (h)(5), and the regulations at 40 CFR part 
720. Once EPA receives a SNUN, EPA must either determine that the 
significant new use is not likely to present an unreasonable risk of 
injury or take such regulatory action as is associated with an 
alternative determination before the manufacture or processing for the 
significant new use can commence. If EPA determines that the 
significant new use is not likely to

[[Page 45992]]

present an unreasonable risk, EPA is required under TSCA section 5(g) 
to make public, and submit for publication in the Federal Register, a 
statement of EPA's findings.

III. Significant New Use Determination

    Section 5(a)(2) of TSCA states that EPA's determination that a use 
of a chemical substance is a significant new use must be made after 
consideration of all relevant factors, including:
     The projected volume of manufacturing and processing of a 
chemical substance.
     The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
     The reasonably anticipated manner and methods of 
manufacturing, processing, distribution in commerce, and disposal of a 
chemical substance.
    In addition to these factors enumerated in TSCA section 5(a)(2), 
the statute authorizes EPA to consider any other relevant factors.
    To determine what would constitute a significant new use for the 
chemical substance identified generically as bimodal mixture consisting 
of multi-walled carbon nanotubes and other classes of carbon nanotubes 
(PMN P-11-482), EPA considered relevant information about the toxicity 
of the chemical substance, likely human exposures and environmental 
releases associated with possible uses, and the four bulleted TSCA 
section 5(a)(2) factors listed in this unit.

IV. Rationale and Objectives for the Rule

A. Rationale

    During review of the PMN P-11-482, the chemical substance 
identified generically as bimodal mixture consisting of multi-walled 
carbon nanotubes and other classes of carbon nanotubes, EPA concluded 
that one or more of the criteria of concern established at Sec.  
721.170 were met. For additional discussion on this chemical substance, 
see Unit II. of this rule.

B. Objectives

    EPA is issuing this SNUR for a specific chemical substance which 
has undergone premanufacture review because the Agency wants to achieve 
the following objectives with regard to the significant new uses 
designated in this rule:
     EPA will receive notice of any person's intent to 
manufacture or process a TSCA Chemical Substance Inventory (TSCA 
Inventory) listed chemical substance for the described significant new 
use before that activity begins.
     EPA will have an opportunity to review and evaluate data 
submitted in a SNUN before the notice submitter begins manufacturing or 
processing a listed chemical substance for the described significant 
new use.
     EPA will be able to either determine that the prospective 
manufacture or processing is not likely to present an unreasonable 
risk, or to take necessary regulatory action associated with any other 
determination, before the described significant new use of the chemical 
substance occurs.
     EPA will ensure that all manufacturers and processors of 
the same chemical substance that is subject to a TSCA section 5(e) 
consent order are subject to similar requirements.
    Issuance of a SNUR for a chemical substance does not signify that 
the chemical substance is listed on the TSCA Inventory. Guidance on how 
to determine if a chemical substance is on the TSCA Inventory is 
available on the Internet at http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

V. Applicability of the Significant New Use Designation

    If uses begun after the proposed rule was published were considered 
ongoing rather than new, any person could defeat the SNUR by initiating 
the significant new use before the final rule was issued. Therefore, 
EPA designated the date of public release/web posting of the proposed 
rule, as the cutoff date for determining whether the new use is 
ongoing. Consult the Federal Register Notice of April 24, 1990 (55 FR 
17376), (FRL-3658-5) for a more detailed discussion of the cutoff date 
for ongoing uses. Any person who began commercial manufacture or 
processing of the chemical substances identified in this rule for any 
of the significant new uses designated in the proposed SNUR after the 
date of publication of the proposed SNUR, must stop that activity 
before the effective date of the final rule. Persons who ceased those 
activities will have to first comply with all applicable SNUR 
notification requirements and wait until the notice review period, 
including any extensions, expires, before engaging in any activities 
designated as significant new uses. If a person were to meet the 
conditions of advance compliance under 40 CFR 721.45(h), the person 
would be considered to have met the requirements of the final SNUR for 
those activities.

VI. Development and Submission of Information

    EPA recognizes that TSCA section 5 does not require developing any 
particular new information (e.g., generating test data) before 
submission of a SNUN. There is an exception: Development of test data 
is required where the chemical substance subject to the SNUR is also 
subject to a rule, order or consent agreement under TSCA section 4 (see 
TSCA section 5(b)(1)).
    In the absence of a TSCA section 4 test rule covering the chemical 
substance, persons are required only to submit information in their 
possession or control and to describe any other information known to or 
reasonably ascertainable by them (see 40 CFR 720.50). However, upon 
review of PMNs and SNUNs, the Agency has the authority to require 
appropriate testing. Descriptions of tests are provided for 
informational purposes. EPA strongly encourages persons, before 
performing any testing, to consult with the Agency pertaining to 
protocol selection. To access the OCSPP test guidelines referenced in 
this document electronically, please go to http://www.epa.gov/ocspp and 
select ``Test Methods and Guidelines.'' The Organisation for Economic 
Co-operation and Development (OECD) test guidelines are available from 
the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at 
http://www.sourceoecd.org.
    In the TSCA section 5(e) consent orders for the chemical substances 
regulated under this rule, EPA has established production volume limits 
in view of the lack of data on the potential health and environmental 
risks that may be posed by the significant new uses or increased 
exposure to the chemical substances. These limits cannot be exceeded 
unless the PMN submitter first submits the results of toxicity tests 
that would permit a reasoned evaluation of the potential risks posed by 
these chemical substances. Under recent TSCA section 5(e) consent 
orders, each PMN submitter is required to submit each study at least 14 
weeks (earlier TSCA section 5(e) consent orders required submissions at 
least 12 weeks) before reaching the specified production limit. 
Listings of the tests specified in the TSCA section 5(e) consent orders 
are included in Unit IV. The SNURs contain the same production volume 
limits as the TSCA section 5(e) consent orders. Exceeding these 
production limits is defined as a significant new use. Persons who 
intend to exceed the

[[Page 45993]]

production limit must notify the Agency by submitting a SNUN at least 
90 days in advance of commencement of non-exempt commercial manufacture 
or processing.
    Any request by EPA for the triggered and pended testing described 
in the Consent Order was made based on EPA's consideration of available 
screening-level data, if any, as well as other available information on 
appropriate testing for the PMN substance. Further, any such testing 
request on the part of EPA that includes testing on vertebrates was 
made after consideration of available toxicity information, 
computational toxicology and bioinformatics, and high-throughput 
screening methods and their prediction models.
    The recommended tests specified in Unit IV. of the proposed rule 
may not be the only means of addressing the potential risks of the 
chemical substance. However, submitting a SNUN without any test data 
may increase the likelihood that EPA will take action under TSCA 
section 5(e), particularly if satisfactory test results have not been 
obtained from a prior PMN or SNUN submitter. EPA recommends that 
potential SNUN submitters contact EPA early enough so that they will be 
able to conduct the appropriate tests.
    SNUN submitters should be aware that EPA will be better able to 
evaluate SNUNs which provide detailed information on the following:
     Human exposure and environmental release that may result 
from the significant new use of the chemical substances.

VII. SNUN Submissions

    According to Sec.  721.1(c), persons submitting a SNUN must comply 
with the same notification requirements and EPA regulatory procedures 
as persons submitting a PMN, including submission of test data on 
health and environmental effects as described in 40 CFR 720.50. SNUNs 
must be submitted on EPA Form No. 7710-25, generated using e-PMN 
software, and submitted to the Agency in accordance with the procedures 
set forth in 40 CFR 720.40 and 721.25. E-PMN software is available 
electronically at https://www.epa.gov/reviewing-new-chemicalsunder-toxic-substances-control-act-tsca/how-submit-e-pmn.

VIII. Economic Analysis

    EPA evaluated the potential costs of establishing SNUN requirements 
for potential manufacturers and processors of the chemical substance 
during the development of the direct final rule. The Agency's complete 
Economic Analysis is available in the docket under docket ID number 
EPA-HQ-OPPT-2016-0207.

IX. Scientific Standards, Evidence, and Available Information

    EPA has used scientific information, technical procedures, 
measures, methods, protocols, methodologies, and models consistent with 
the risk assessment documents included in the public docket. These 
information sources supply information relevant to whether a particular 
use would be a significant new use, based on relevant factors including 
those listed under TSCA section 5(a)(2).
    The clarity and completeness of the data, assumptions, methods, 
quality assurance, and analyses employed in EPA's decision are 
documented, as applicable and to the extent necessary for purposes of 
this proposed significant new use rule, in Unit II and in the documents 
noted above. EPA recognizes, based on the available information, that 
there is variability and uncertainty in whether any particular 
significant new use would actually present an unreasonable risk. For 
precisely this reason, it is appropriate to secure a future notice and 
review process for these uses, at such time as they are known more 
definitely. The extent to which the various information, procedures, 
measures, methods, protocols, methodologies or models used in EPA's 
decision have been subject to independent verification or peer review 
is adequate to justify their use, collectively, in the record for a 
significant new use rule.

X. Statutory and Executive Order Reviews

A. Executive Order 12866

    This action establishes a SNUR for the chemical substance that is 
the subject of a PMN and a TSCA section 5(e) consent order. The Office 
of Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993).

B. Paperwork Reduction Act (PRA)

    According to the PRA, (44 U.S.C. 3501 et seq.), an agency may not 
conduct or sponsor, and a person is not required to respond to a 
collection of information that requires OMB approval under PRA, unless 
it has been approved by OMB and displays a currently valid OMB control 
number. The OMB control numbers for EPA's regulations in title 40 of 
the CFR, after appearing in the Federal Register, are listed in 40 CFR 
part 9, and included on the related collection instrument or form, if 
applicable.
    EPA is amending the table in 40 CFR part 9 to list the OMB approval 
number for the information collection requirements contained in this 
rule. This listing of the OMB control numbers and their subsequent 
codification in the CFR satisfies the display requirements of PRA and 
OMB's implementing regulations at 5 CFR part 1320. This Information 
Collection Request (ICR) was previously subject to public notice and 
comment prior to OMB approval, and given the technical nature of the 
table, EPA finds that further notice and comment to amend it is 
unnecessary. As a result, EPA finds that there is ``good cause'' under 
section 553(b)(3)(B) of the Administrative Procedure Act, 5 U.S.C. 
553(b)(3)(B), to amend this table without further notice and comment.
    The information collection requirements related to this action have 
already been approved by OMB pursuant to PRA under OMB control number 
2070-0012 (EPA ICR No. 574). This action does not impose any burden 
requiring additional OMB approval. If an entity were to submit a SNUN 
to the Agency, the annual burden is estimated to average between 30 and 
170 hours per response. This burden estimate includes the time needed 
to review instructions, search existing data sources, gather and 
maintain the data needed, and complete, review, and submit the required 
SNUN.
    Send any comments about the accuracy of the burden estimate, and 
any suggested methods for minimizing respondent burden, including 
through the use of automated collection techniques, to the Director, 
Collection Strategies Division, Office of Environmental Information 
(2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW., 
Washington, DC 20460-0001. Please remember to include the OMB control 
number in any correspondence, but do not submit any completed forms to 
this address.

C. Regulatory Flexibility Act (RFA)

    On February 18, 2012, EPA certified pursuant to RFA section 605(b) 
(5 U.S.C. 601 et seq.), that promulgation of a SNUR does not have a 
significant economic impact on a substantial number of small entities 
where the following are true:
    1. A significant number of SNUNs would not be submitted by small 
entities in response to the SNUR.
    2. The SNUR submitted by any small entity would not cost 
significantly more than $8,300.
    A copy of that certification is available in the docket for this 
action.

[[Page 45994]]

    This action is within the scope of the February 18, 2012 
certification. Based on the Economic Analysis discussed in Unit IX. and 
EPA's experience promulgating SNURs (discussed in the certification), 
EPA believes that the following are true:
     A significant number of SNUNs would not be submitted by 
small entities in response to the SNUR.
     Submission of the SNUN would not cost any small entity 
significantly more than $8,300.
    Therefore, the promulgation of the SNUR would not have a 
significant economic impact on a substantial number of small entities.

D. Unfunded Mandates Reform Act (UMRA)

    Based on EPA's experience with proposing and finalizing SNURs, 
State, local, and Tribal governments have not been impacted by these 
rulemakings, and EPA does not have any reasons to believe that any 
State, local, or Tribal government will be impacted by this final rule. 
As such, EPA has determined that this final rule does not impose any 
enforceable duty, contain any unfunded mandate, or otherwise have any 
effect on small governments subject to the requirements of UMRA 
sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 13132

    This action will not have a substantial direct effect on States, on 
the relationship between the national government and the States, or on 
the distribution of power and responsibilities among the various levels 
of government, as specified in Executive Order 13132, entitled 
``Federalism'' (64 FR 43255, August 10, 1999).

F. Executive Order 13175

    This final rule does not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This 
final rule does not significantly nor uniquely affect the communities 
of Indian Tribal governments, nor does it involve or impose any 
requirements that affect Indian Tribes. Accordingly, the requirements 
of Executive Order 13175, entitled ``Consultation and Coordination with 
Indian Tribal Governments'' (65 FR 67249, November 9, 2000), do not 
apply to this final rule.

G. Executive Order 13045

    This action is not subject to Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997), because this is not an 
economically significant regulatory action as defined by Executive 
Order 12866, and this action does not address environmental health or 
safety risks disproportionately affecting children.

H. Executive Order 13211

    This action is not subject to Executive Order 13211, entitled 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001), because 
this action is not expected to affect energy supply, distribution, or 
use and because this action is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    In addition, since this action does not involve any technical 
standards, NTTAA section 12(d) (15 U.S.C. 272 note), does not apply to 
this action.

J. Executive Order 12898

    This action does not entail special considerations of environmental 
justice related issues as delineated by Executive Order 12898, entitled 
``Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations'' (59 FR 7629, February 16, 
1994).

XI. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This rule is not a ``major rule'' as 
defined by 5 U.S.C. 804(2).

4. Add Sec.  721.10927 to subpart E to read as follows:

Sec.  721.10927  Bimodal mixture consisting of multi-walled carbon 
nanotubes and other classes of carbon nanotubes (generic).

    (a) Chemical substance and significant new uses subject to 
reporting. (1) The chemical substance identified generically as a 
bimodal mixture consisting of multi-walled carbon nanotubes and other 
classes of carbon nanotubes (PMN P-11-482) is subject to reporting 
under this section for the significant new uses described in paragraph 
(a)(2) of this section.
    (2) The significant new uses are:
    (i) Protection in the workplace. Requirements as specified in Sec.  
721.63(a)(1), (a)(2)(i), (a)(2)(ii), (a)(3), (a)(4), (a)(6) 
(particulate), and (c). When determining which persons are reasonably 
likely to be exposed as required for Sec.  721.63(a)(1) and (a)(4), 
engineering control measures (e.g., enclosure or confinement of the

[[Page 45995]]

operation, general and local ventilation) or administrative control 
measures (e.g., workplace policies and procedures) shall be considered 
and implemented to prevent exposure, where feasible. A National 
Institute for Occupational Safety and Health (NIOSH)-certified air 
purifying, tight-fitting full-face respirator equipped with N-100, P-
100, or R-100 cartridges, or power air purifying particulate respirator 
with an Assigned Protection Factor (APF) of at least 50 meets the 
requirements of Sec.  721.63(a)(4).
    (ii) Industrial, commercial, and consumer activities. Requirements 
as specified in Sec.  721.80(k) and (q). A significant new use is any 
use involving an application method that generates a vapor, mist or 
aerosol.
    (iii) Disposal. Requirements as specified in Sec.  721.85(a)(1), 
(a)(2), (b)(1), (b)(2), (c)(1), and (c)(2).
    (iv) Release to water. Requirements as specified in Sec.  
721.90(b)(1) and (c)(1). Any predictable or purposeful release of a 
manufacturing stream associated with any use of the substance from any 
site is a significant new use other than the water releases described 
in the manufacturing process of PMN P-11-482.
    (b) Specific requirements. The provisions of subpart A of this part 
apply to this section except as modified by this paragraph.
    (1) Recordkeeping. Recordkeeping requirements as specified in Sec.  
721.125(a) through (e), (i), (j), and (k) are applicable to 
manufacturers and processors of this substance.
    (2) Limitations or revocation of certain notification requirements. 
The provisions of Sec.  721.185 apply to this section.
    (3) Determining whether a specific use is subject to this section. 
The provisions of Sec.  721.1725(b)(1) apply to paragraph (a)(2)(ii) of 
this section.
