Significant New Use Rules on Certain 
Chemical Substances 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Direct final rule. 
SUMMARY : EPA is promulgating 
significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 29 chemical substances which were the subject of premanufacture notices (PMNs). The chemical substances are subject to consent orders issued by EPA pursuant to section 5(e) of TSCA. This action requires persons who intend to manufacture (defined by statute to include import) or process any of these 29 chemical substances for an activity that is designated as a significant new use by this 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. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination. 
DATES : This rule is effective on 
December 18, 2017. For purposes of judicial review, this rule shall be promulgated at 1 p.m. (e.s.t.) on November 2, 2017. 
Written adverse or critical comments, 
or notice of intent to submit adverse or critical comments, on one or more of these SNURs must be received on or before November 20, 2017 (see Unit VI. of the 
SUPPLEMENTARY INFORMATION ). If 
EPA receives written adverse or critical comments, or notice of intent to submit adverse or critical comments, on one or more of these SNURs before November 20, 2017, EPA will withdraw the relevant sections of this direct final rule before its effective date. 
For additional information on related 
reporting requirement dates, see Units I.A., VI., and VII. of the 
SUPPLEMENTARY

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 these SNURs 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, pursuant to 40 CFR 721.20, any persons who export or intend to export a chemical substance that is the subject of this rule on or after November 20, 2017 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) and must comply with the export notification requirements in 40 CFR part 707, subpart D. 
B. What should I consider as I prepare 
my comments for EPA? 
1. Submitting CBI. Do not submit this 
information to EPA through regulations.gov or email. Clearly mark 
the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 
2. Tips for preparing your comments. 
When preparing and submitting your comments, see the commenting tips at http://www.epa.gov/dockets/ comments.html. 
II. Background A. What action is the Agency taking? 
EPA is promulgating these SNURs 
using direct final procedures. These 
SNURs will require persons to notify EPA at least 90 days before commencing the manufacture or processing of a chemical substance for any activity designated by these SNURs as a significant new use. Receipt of such notices allows EPA to assess risks that may be presented by the intended uses and, if appropriate, to regulate the proposed use before it occurs. Additional rationale and background to these rules are more fully set out in the 
preamble to EPA’s first direct final SNUR published in the Federal Register issue of April 24, 1990 (55 FR 17376). Consult that preamble for further information on the objectives, rationale, and procedures for SNURs and on the basis for significant new use designations, including provisions for developing test data. 
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. Once EPA determines that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B)(i) (15 U.S.C. 2604(a)(1)(B)(i)) requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture or process the chemical substance for that use. TSCA 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. 
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 rule. Provisions relating to user fees appear at 40 CFR part 700. Pursuant to § 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) (15 U.S.C. 2604(a)(1)(A)). In particular, these requirements include the information submission requirements of TSCA sections 5(b) and 5(d)(1) (15 U.S.C. 2604(b) and 2604(d)(1)), the exemptions authorized by TSCA sections 5(h)(1), 5(h)(2), 5(h)(3), and 5(h)(5) (15 U.S.C. 2604(h)(1), 2604(h)(2), 2604(h)(3), and 2604(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 present an unreasonable risk, EPA is required under TSCA section 5(g) (15 U.S.C. 2604(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 authorized EPA to consider any other relevant factors. 
To determine what would constitute a 
significant new use for the 37 chemical substances that are the subject of these SNURs, EPA considered relevant information about the toxicity of the chemical substances, 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. Substances Subject to This Rule 
EPA is establishing significant new 
use and recordkeeping requirements for 
29 chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance: 
•PMN number. 
•Chemical name (generic name, if 
the specific name is claimed as CBI). 
•Chemical Abstracts Service (CAS) 
Registry number (if assigned for non- confidential chemical identities). 
•Basis for the consent order under 
TSCA section 5(e) (15 U.S.C. 2604(e)). 
•Tests recommended by EPA to 
provide sufficient information to evaluate the chemical substance (see Unit VIII. for more information). 
•CFR citation assigned in the 
regulatory text section of this rule. 
The regulatory text section of this rule 
specifies the activities designated as

significant new uses. Certain new uses, 
including production volume limits (i.e., limits on manufacture volume) and 
other uses designated in this rule, may be claimed as CBI. Unit IX. discusses a procedure companies may use to ascertain whether a proposed use constitutes a significant new use. 
This rule includes 29 PMN substances 
that are subject to ‘‘risk-based’’ consent orders under TSCA section 5(e)(1)(A)(ii)(I) (15 U.S.C. 2604(e)(1)(A)(ii)(I)) where EPA determined that activities associated with the PMN substances may present unreasonable risk to human health or the environment. Those consent orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The SNURs are promulgated pursuant to § 721.160, and are based on and consistent with the provisions in the underlying consent orders. The SNURs designate as a ‘‘significant new use’’ the absence of the protective measures required in the corresponding consent orders. 
Where EPA determined that the PMN 
substance may present an unreasonable risk of injury to human health via inhalation exposure, the underlying TSCA section 5(e) consent order usually requires, among other things, that potentially exposed employees wear specified respirators unless actual measurements of the workplace air show that air-borne concentrations of the PMN substance are below a New Chemical Exposure Limit (NCEL) that is established by EPA to provide adequate protection to human health. In addition to the actual NCEL concentration, the comprehensive NCELs provisions in TSCA section 5(e) consent orders, which are modeled after Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELs) provisions, include requirements addressing performance criteria for sampling and analytical methods, periodic monitoring, respiratory protection, and recordkeeping. However, no comparable NCEL provisions currently exist in 40 CFR part 721, subpart B, for SNURs. Therefore, for these cases, the individual SNURs in 40 CFR part 721, subpart E, will state that persons subject to the SNUR who wish to pursue NCELs as an alternative to the § 721.63 respirator requirements may request to do so under § 721.30. EPA expects that persons whose requests under § 721.30 to use the NCELs approach for SNURs are approved by EPA will be required to comply with NCELs provisions that are comparable to those contained in the corresponding TSCA section 5(e) consent order for the same chemical substance. 
PMN Number: P–15–310 
Chemical name: 1,2,4- 
Benzenetricarboxylic acid, mixed decyl 
and octyl triesters. 
CAS number: Not available. 
Effective date of TSCA section 5(e) 
consent order: January 31, 2017. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substance will be used as a lubricant in 
special chain oils for conveyor belts. Based on submitted test data, EPA predicts blood and adrenal gland effects to unprotected workers from repeated dermal exposures. EPA also predicts endocrine disruption based on Structure Activity Relationship (SAR) analysis on analogous phthalates. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to human health. To protect against these risks, the consent order requires: 
1. Use of personal protective 
equipment to prevent dermal exposure. 
2. Not use, formulate, or distribute for 
use other than as stated in the PMN. 
3. No manufacture beyond an annual 
production volume of 150,000 kg. 
Recommended testing: EPA has 
determined that the results of certain human health toxicity testing would help characterize the PMN substance. The submitter has agreed not to exceed the confidential production limit without performing an Extended One- Generation Reproductive Toxicity Study (OECD Test Guideline 443).

PMN Numbers: P–15–487, P–15–488, P– 15–489, P–15–490, and P–15–491 
Chemical names: Multi-walled carbon 
nanotubes (generic). 
CAS numbers: Not available. 
Effective date of TSCA section 5(e) 
consent order: February 17, 2017. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substances will be used as additives for 
electro-static discharge (ESD) in electronic devices, electronics, and materials; additives for weight reduction in materials; additives to improve mechanical properties or electrical conductivities; heat-generating elements in heating devices and materials; additives for heat transfer and thermal emissions in electronic devices and materials; semi-conductor, conductive, or resistive elements in electronic circuitry and devices; additives to improve conductivity in electronic circuitry, energy storage systems, and devices; electron emitters for lighting 
and x-ray sources; additive for electromagnetic interface shielding in electronic devices; additives for electrodes in electronic materials and electronic devices; catalyst support in chemical manufacturing; coating additives to improve corrosion resistance or conductive properties; additives for fibers in structural and electrical applications; additives for fibers in fabrics and textiles; filter additives to remove nanoscale materials; semi-conducting compounding additives far high-voltage cable; and additives for super-hydrophobicity. A submitted 90-day inhalation toxicity study for P–15–487 demonstrated no effects at 1 mg/m
3, which was the 
highest dose tested. Based on SAR analysis on analogous carbon nanotubes (CNT), EPA predicts pulmonary toxicity and oncogenicity to unprotected workers from repeated inhalation exposures. No ecotoxicity studies on CNT are available in which a broad range of production methods, sources, purification, functionalization, etc. were investigated. EPA expects that some fraction of the PMN substances, if released into the environment, will eventually become suspended in water. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substances may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the consent order requires: 
1. Use of personal protective 
equipment to prevent dermal exposure 
and a NIOSH-certified respirator with N–100, P–100, or R–100 cartridges with an assigned protection factor (APF) of at least 50 (where there is a potential for inhalation exposure). 
2. Use of the PMN substances only for 
the uses specified in the consent order. 
3. No use in application methods that 
generate a dust, mist, or aerosol unless such application method occurs in an enclosed process. 
4. No use of the PMN substances 
resulting in releases to surface waters and disposal of the PMN substances only by landfill or incineration. 
Recommended testing: EPA has 
determined that a subchronic 90-day inhalation toxicity study (OPPTS 870.3465 or OECD 413), a two-year inhalation bioassay (OPPTS 870.4200), a fish early-life stage toxicity test (OCSPP Test Guideline 850.1400), a daphnid chronic toxicity test (OCSPP Test Guideline 850.1300), and an algal toxicity test (OCSPP Test Guideline 850.4500) would help characterize possible health and environmental

(2+) salt (2:1). 
CAS number: 1952336–63–8. 
Effective date of TSCA section 5(e) 
consent order: February 15, 2017. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substance will be used as a component 
in a metal organic product that will be used in paint and ink driers, unsaturated polyester resins promoters, lube/grease additives, fuel additives, polymerization catalysts, and specialty petrochemical catalysts at less than 1 percent. Based on submitted test data, EPA predicts liver and developmental toxicity to unprotected workers from repeated inhalation exposures. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to human health. To protect against these risks, the consent order requires: 
1. Use of a NIOSH-certified respirator 
with an APF of at least 10 (where there is a potential for inhalation exposures). 
2. Establishment and use of a hazard 
communication program, including human health precautionary statements on each label and in the Safety Data Sheet (SDS). 
3. No manufacture beyond an annual 
production volume of 150,000 kg. 
4. Not process or use the PMN 
substance for non-industrial applications. 
5. Not process or use the PMN 
substance in formulations where the concentration is greater than 1%. 
Recommended testing: EPA has 
determined that the results of certain human health toxicity testing would help characterize the PMN substance. The submitter has agreed not to exceed the confidential production limit without performing the prenatal development toxicity study (OECD 414). In addition, EPA has determined that the results of a combined chronic toxicity and carcinogenicity toxicity test (OPPTS 870.4300) would help characterize the health effects of the PMN substance. The Order’s restrictions on manufacture, processing, distribution in commerce, and disposal will remain in effect until the Order is modified or revoked by EPA based on submission of this or other relevant information.

Effective date of TSCA section 5(e) 
consent order: March 7, 2017. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substances will be used as blocked catalysts for paints and coatings. Based on submitted test data, EPA predicts strong irritation to the skin, eyes, and mucous membranes as well as acute toxicity and corrosivity-related neurotoxicity from repeated dermal and inhalation exposures. Further, based on test data on the PMN substances, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 34 parts per billion (ppb) of the PMN substances in surface waters. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substances may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the consent order requires: 
1. Use of personal protective 
equipment to prevent dermal exposures. 
2. Establishment and use of a hazard 
communication program, including human health precautionary statements on each label and in a safety data sheet (SDS). 
3. Use of the PMN substances only for 
the use specified in the consent order. 
4. Use of the PMN substances at a 
concentration no greater than 1.5% by weight in the final product. 
Recommended testing: EPA has 
determined that the results of certain environmental toxicity testing would help characterize the PMN substances. The submitter has agreed not to exceed the confidential production limit without performing a daphnid chronic toxicity test (OCSPP 850.1300). 
CFR citations: 40 CFR 721.10999 (P–

CAS number: Not available. 
Effective date of TSCA section 5(e) 
consent order: May 12, 2017. 
Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substance will be used as an optical 
brightener for textiles, paper, and paperboard. Based on submitted test data, EPA predicts adrenal gland effects to unprotected workers from repeated dermal and inhalation exposures. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to human health. To protect against these risks, the consent order requires: 
(1) Import only of the PMN substance 
as a solution. 
(2) Use only as an optical brightener 
for textiles, paper and paperboard. 
(3) No use of the PMN substance in 
application methods that generate a dust, mist, or aerosol unless such application method occurs in an enclosed process. 
(4) Non industrial use only where the 
PMN substance is not sold for ‘‘consumer use’’ or for ‘‘commercial uses’’ (as the term is defined in § 721.3) when the ‘‘saleable goods or service’’ could introduce PMN material into a ‘‘consumer’’ setting (as that term is defined in § 721.3). 
Recommended testing: EPA has 
determined that the results of physical/ chemistry testing would help characterize the PMN substance. The submitter has agreed not to manufacture beyond a certain time period without measuring the particle size distribution to characterize the particle size distribution of fractions less than 10 microns of the dry particle PMN substance. In addition, EPA has determined that the results of a 90-day subchronic inhalation toxicity study (OPPTS 870.3465 or OECD 413) would help characterize the health effects of the PMN substance. The Order’s restrictions on manufacture, processing, distribution in commerce, and disposal will remain in effect until the Order is modified or revoked by EPA based on submission of this or other relevant information.

order: The PMN states that the PMN 
substances will be used as rheological or 
thixotropic agents used in the production of solvent based industrial coatings, high solid aromatic paints, adhesives, sealants, and other types of paints and topcoats. Based on submitted test data, EPA predicts blood and hematology effects. Further, based on SAR analysis of test data on analogous amides, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 2 ppb of the PMN substances in surface waters. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substances may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the consent order requires: 
(1) No domestic manufacture of the 
PMN substances. 
(2) No manufacture beyond the 
annual production volume specified in the consent order. 
(3) Use of the PMN substances only 
for the use specified in the consent order. 
(4) Compliance with the release to 
water provisions. 
Recommended testing: EPA has 
determined that the results of certain human health and environmental toxicity testing would help characterize the PMN substances. The submitter has agreed not to exceed the confidential production limit without performing a fish early-life stage toxicity test (OCSPP Test Guideline 850.1400), a daphnid chronic toxicity test (OCSPP Test Guideline 850.1300), and an algal toxicity test (OCSPP Test Guideline 850.1300). In addition, EPA has determined that the results of a repeated dose dermal toxicity test (OPPTS Test Guideline 870.3200) would help characterize the human health effects of the PMN substances.

Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substance will be used as a fuel 
additive. Based on physical/chemical properties, EPA estimates the PMN substance would have low environmental hazard due to its poor water solubility. However, if the number of repeating ethylene oxide units in the polymer is large (i.e., greater than 10), 
the polymer would become a dispersible surfactant. Based on SAR analysis of test data on an analogous nonionic polymer, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 350 ppb of the PMN substance in surface waters. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to the environment. To protect against these risks, the consent order requires manufacture such that no more than 33% of the PMN substance contains 10 or more repeating ethylene oxide units. 
Recommended testing: EPA has 
determined that an acute invertebrate toxicity test, freshwater daphnids (OCSPP Test Guideline 850.1010), a fish acute toxicity test, freshwater and marine (OCSPP Test Guideline 850.1075), a fish early-life stage toxicity test (OCSPP Test Guideline 850.1400), a daphnid chronic toxicity test (OCSPP Test Guideline 850.1300), and an algal toxicity test (OCSPP Test Guideline 850.4500) would help characterize possible environmental effects of the substance.

The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to human health. To protect against these risks, the consent order requires: 
(1) Distribution of the PMN substance 
only in a liquid or gel formulation, unless the solid particle form has a particle size distribution where less than 0.5% of the particles are less than 10 microns. 
(2) No use in application methods that 
generate a dust, mist, or aerosol unless such application method occurs in an enclosed process. 
Recommended testing: EPA has 
determined that the results of physical/ chemical characteristics would help characterize the PMN substance. The submitter has agreed not to manufacture beyond a certain time period without measuring the particle size distribution to characterize the particle size distribution of fractions less than 10 microns of the dry particle PMN substance.

Basis for TSCA section 5(e) consent 
order: The PMN states that the PMN 
substance will be used as a site-limited 
polymer intermediate for production of a deck stain coating resin additive. Based on physical/chemical properties, EPA predicts low health hazard for the PMN substance when it is manufactured as described in the PMN. However, if the chemical substance is manufactured with a lower molecular weight and a higher proportion of the acid component (i.e., greater than 20%), the 
PMN substance could cause developmental effects in unprotected workers from repeated dermal and inhalation exposures. Further, based on physical/chemical properties, EPA predicts low hazard for the PMN substance when it is manufactured as described in the PMN due to low water solubility. However, if the chemical substance is manufactured with a higher proportion of the acid component (i.e., greater than 20%), there is potential for aquatic toxicity. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that the substance may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the consent order requires: 
1. Manufacture of the PMN substance 
to have an average molecular weight no less than 1500 daltons. 
2. Manufacture of the PMN substance 
to have no more than 24% by weight of the acid component. 
3. Use of the PMN substance only as 
intermediate. 
Recommended testing: EPA has 
determined that a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD 422), water solubility test, log Kow tests, a compositional/component analysis (certificate of analysis), a fish early-life stage toxicity test (OCSPP Test Guideline 850.1400), a daphnid chronic toxicity test (OCSPP Test Guideline 850.1300), fish acute toxicity mitigated by humic acid (OCSPP Test Guideline 850.1085), an aquatic invertebrate, acute toxicity test, freshwater daphnids (OCSPP Test Guideline 850.1075), and an algal toxicity test (OCSPP Test Guideline 850.4500) would help characterize the physical-chemical properties and possible health and environmental effects of the substance.

V. Rationale and Objectives of the Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are 
subject to these SNURs, EPA concluded that for all 29 chemical substances, regulation was warranted under TSCA section 5(e), pending the development of information sufficient to make reasoned evaluations of the health or environmental effects of the chemical substances. The basis for such findings is outlined in Unit IV. Based on these findings, TSCA section 5(e) consent orders requiring the use of appropriate exposure controls were negotiated with the PMN submitters. The SNUR provisions for these chemical substances are consistent with the provisions of the TSCA section 5(e) consent orders. These SNURs are promulgated pursuant to § 721.160 (see Unit VI.). 
B. Objectives 
EPA is issuing these SNURs for 
specific chemical substances which 
have 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.

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. 
VI. Direct Final Procedures 
EPA is issuing these SNURs as a 
direct final rule, as described in 
§ 721.160(c)(3). In accordance with § 721.160(c)(3)(ii) the effective date of this rule is December 18, 2017 without further notice, unless EPA receives written adverse or critical comments, or notice of intent to submit adverse or critical comments before November 20, 2017. 
If EPA receives written adverse or 
critical comments, or notice of intent to submit adverse or critical comments, on one or more of these SNURs before November 20, 2017, EPA will withdraw the relevant sections of this direct final rule before its effective date. EPA will then issue a proposed SNUR for the chemical substance(s) on which adverse or critical comments were received, providing a 30-day period for public comment. 
This rule establishes SNURs for a 
number of chemical substances. Any person who submits adverse or critical comments, or notice of intent to submit adverse or critical comments, must identify the chemical substance and the new use to which it applies. EPA will not withdraw a SNUR for a chemical substance not identified in the comment. 
VII. Applicability of the Significant 
New Use Designation 
To establish a significant new use, 
EPA must determine that the use is not ongoing. The chemical substances subject to this rule have undergone premanufacture review. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for chemical substances for which an NOC has not been submitted EPA concludes that the designated significant new uses are not ongoing. When chemical substances identified 
in this rule are added to the TSCA 
Inventory, EPA recognizes that, before the rule is effective, other persons might engage in a use that has been identified as a significant new use. However, TSCA section 5(e) consent orders have been issued for these chemical substances, and the PMN submitters are prohibited by the TSCA section 5(e) consent orders from undertaking activities which would be designated as significant new uses. The identities of 19 of the 29 chemical substances subject to this rule have been claimed as confidential and EPA has received no post-PMN bona fide submissions (per 
§§ 720.25 and 721.11). Based on this, the Agency believes that it is highly unlikely that any of the significant new uses described in the regulatory text of this rule are ongoing. 
Therefore, EPA designates July 10, 
2017 (the date of public release/web posting of this rule) as the cutoff date for determining whether the new use is ongoing. This designation varies slightly from EPA’s past practice of designating the date of Federal Register publication as the date for making this determination. The objective of EPA’s approach has been to ensure that a person could not defeat a SNUR by initiating a significant new use before the effective date of the direct final rule. In developing this rule, EPA has recognized that, given EPA’s practice of now posting rules on its Web site a week or more in advance of Federal Register publication, this objective 
could be thwarted even before that publication. Thus, EPA has slightly modified its approach in this rulemaking and plans to follow this modified approach in future significant new use rulemakings. 
Persons who begin commercial 
manufacture or processing of the chemical substances for a significant new use identified as of that date would have to cease any such activity upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and wait until the notice review period, including any extensions, expires. If such a person met the conditions of advance compliance under § 721.45(h), the person would be considered exempt from the requirements of the SNUR. Consult the Federal Register document of April 24, 1990 for a more detailed discussion of the cutoff date for ongoing uses. VIII. 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: TSCA section 5(b)(1) requires development of test data where the chemical substance subject to the SNUR is also subject to a rule, order or consent agreement under TSCA section 4 (15 U.S.C. 2603). 
In the absence of a rule order, or 
consent agreement under TSCA section 4 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 § 720.50). However, upon review of PMNs and SNUNs, the Agency has the authority to require appropriate testing. Unit IV. lists required or recommended testing for all of the listed SNURs. 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 tests specified in the order 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 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. 
The recommended tests specified in 
Unit IV. 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. 
•Potential benefits of the chemical 
substances. 
•Information on risks posed by the 
chemical substances compared to risks posed by potential substitutes. 
IX. Procedural Determinations 
By this rule, EPA is establishing 
certain significant new uses which have 
been claimed as CBI subject to Agency confidentiality regulations at 40 CFR part 2 and 40 CFR part 720, subpart E. Absent a final determination or other disposition of the confidentiality claim under 40 CFR part 2 procedures, EPA is required to keep this information confidential. EPA promulgated a procedure to deal with the situation where a specific significant new use is CBI, at § 721.1725(b)(1). 
Under these procedures a 
manufacturer or processor may request EPA to determine whether a proposed use would be a significant new use under the rule. The manufacturer or processor must show that it has a bona fide intent to manufacture or process the 
chemical substance and must identify the specific use for which it intends to manufacture or process the chemical substance. If EPA concludes that the person has shown a bona fide intent to manufacture or process the chemical substance, EPA will tell the person whether the use identified in the bona fide submission would be a significant 
new use under the rule. Since most of the chemical identities of the chemical substances subject to these SNURs are also CBI, manufacturers and processors can combine the bona fide submission under the procedure in § 721.1725(b)(1) with that under § 721.11 into a single 
step. 
If EPA determines that the use 
identified in the bona fide submission would not be a significant new use, i.e., the use does not meet the criteria specified in the rule for a significant new use, that person can manufacture or process the chemical substance so long as the significant new use trigger is not met. In the case of a production volume trigger, this means that the aggregate annual production volume does not exceed that identified in the bona fide submission to EPA. Because of confidentiality concerns, EPA does not typically disclose the actual production volume that constitutes the use trigger. Thus, if the person later intends to exceed that volume, a new bona fide submission would be necessary to determine whether that higher volume would be a significant new use. 
X. SNUN Submissions 
According to § 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 § 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 §§ 720.40 and 721.25. E–PMN software is available electronically at https://www.epa.gov/ reviewing-new-chemicals-under-toxic- substances-control-act-tsca. 
XI. Economic Analysis 
EPA has evaluated the potential costs 
of establishing SNUN requirements for 
potential manufacturers and processors of the chemical substances subject to this rule. EPA’s complete economic 
analysis is available in the docket under docket ID number EPA–HQ–OPPT– 2017–0166. 
XII. Statutory and Executive Order 
Reviews 
A. Executive Order 12866 
This action establishes SNURs for 
several new chemical substances that 
were the subject of PMNs, or TSCA section 5(e) consent orders. 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 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 action. 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. 
605(b)), that promulgation of a SNUR does not have a significant economic impact on a substantial number of small entities where the following are true: 
VerDate Sep<11>2014 14:12 Oct 18, 2017 Jkt 244001 PO 00000 Frm 00038 Fmt 4700 Sfmt 4700 E:\FR\FM\19OCR1.SGM 19OCR1rmajette on DSKBCKNHB2PROD with RULES48647 Federal Register / Vol. 82, No. 201 / Thursday, October 19, 2017 / Rules and Regulations 
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. 
This action is within the scope of the 
February 18, 2012 certification. Based on the Economic Analysis discussed in Unit XI. 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 action. As such, EPA has determined that this action 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. 1502, 1503, 1504, or 1505 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 action does not have Tribal 
implications because it is not expected 
to have substantial direct effects on Indian Tribes. This action 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 action. 
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). 
XIII. 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 action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

(ii) Industrial, commercial, and 
consumer activities. Requirements as specified in § 721.80(p) (2,440,000 kilograms), (s) (150,000 kilograms). It is a significant new use to use the PMN substance other than as a lubricant in chain oils for conveyor belts. 
(iii) Hazard communication program. 
A significant new use of the substance is any manner or method of manufacture or processing associated with any use of the substance without providing risk notification as follows: 
(A) If as a result of the test data 
required under the TSCA section 5(e) consent order for the substance, the employer becomes aware that the substance may present a risk of injury to human health or the environment, the employer must incorporate this new information, and any information on methods for protecting against such risk, into a MSDS as described in § 721.72(c) within 90 days from the time the employer becomes aware of the new information. If the substance is not being manufactured, processed, or used in the employer’s workplace, the employer must add the new information to a MSDS before the substance is reintroduced into the workplace. 
(B) The employer must ensure that 
persons who will receive the PMN substance from the employer, or who have received the PMN substance from the employer within 5 years from the date the employer becomes aware of the new information described in paragraph (a)(2)(iii)(A) of this section, are provided an MSDS containing the information required under paragraph (a)(2)(iii)(A) of this section within 90 days from the time the employer becomes aware of the new information. (b) Specific requirements. The

SUPPLEMENTARY INFORMATION : In 
December 2016, PHMSA issued an interim final rule (IFR) titled: ‘‘Pipeline 
Safety: Underground Natural Gas Storage Facilities’’ (81 FR 91860). In the IFR, PHMSA established minimum federal safety standards for intrastate and interstate underground natural gas storage facilities under its regulatory authority at 49 U.S.C. 60101 and 60102 and as directed by section 12 of the ‘‘Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016.’’ On January 18, 2017, the American Gas Association, the American Petroleum Institute, the American Public Gas Association, and the Interstate Natural Gas Association of America (INGAA) jointly submitted a petition seeking reconsideration of certain provisions of the IFR. (INGAA has since withdrawn from the petition.) 
Recognizing that the IFR set certain 
deadlines by which the operators of underground natural gas storage facilities must act but that would occur before PHMSA could adopt a final rule, PHMSA published a notice on June 20, 2017, in the Federal Register (82 FR 28224), announcing that (1) the agency would not issue enforcement citations to operators for non-compliance with certain provisions of the IFR for a period of one year after publication of the final rule, and (2) it intended to address the issues raised by the petitioners in the final rule. For these reasons, PHMSA is now providing the public with an additional opportunity to comment on the IFR and an opportunity to comment on the issues raised in the petition. PHMSA is therefore reopening the comment period for this IFR until November 20, 2017. All documents and comments related to this matter are available for review at http://www.regulations.gov in docket number 
PHMSA–2016–0016.
