Significant New Use Rules on Certain Chemical Substances (19-2.F)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing significant new use rules (SNURs) under the 
Toxic Substances Control Act (TSCA) for 31 chemical substances which 
were the subject of premanufacture notices. 7 of these chemical 
substances are subject to Orders issued by EPA pursuant to TSCA section 
5(e). This action would require persons who intend to manufacture 
(defined by statute to include import) or process any of these 31 
chemical substances for an activity that is proposed as a significant 
new use to notify EPA at least 90 days before commencing that activity. 
The required notification initiates EPA's evaluation of the use, under 
the conditions of use for that chemical substance, 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 by that determination.

DATES: Comments must be received on or before September 5, 2019.

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 substances contained in this proposed 
rule. 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 or processors of one or more subject 
chemical substances (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 final 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, any persons who export or intend to export a chemical 
substance that is the subject of this proposed rule on or after 
September 5, 2019 are subject to the export notification provisions of 
TSCA section 12(b) (15 U.S.C. 2611(b)) (see 40 CFR 721.20), 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

[[Page 38159]]

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 https://www.epa.gov/dockets/comments.html.

II. Background

A. What action is the Agency taking?

    EPA is proposing these SNURs under TSCA section 5(a)(2) for 
chemical substances that were the subject of PMNs and an MCAN. These 
proposed SNURs would require persons to notify EPA at least 90 days 
before commencing the manufacture or processing of a chemical substance 
for any activity proposed as a significant new use. Receipt of such 
notices would allow EPA to assess risks and, if appropriate, to 
regulate the significant new use before it may occur. Additional 
background regarding SNURs is 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 
general 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) 
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 (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)).

C. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to the proposed rule, 
recordkeeping requirements, and 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 Sec.  721.1(c), persons subject to 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), (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 use is not likely to present an unreasonable risk of injury under 
the conditions of use for the chemical substance or take such 
regulatory action as is associated with an alternative determination 
before the manufacture or processing for the significant new use can 
commence. In the case of a determination other than not likely to 
present unreasonable risk, the applicable review period must also 
expire before manufacturing or processing for the new use may commence. 
If EPA determines that the use is not likely to 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

    TSCA section 5(a)(2) 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 determining significant new use for the 31 chemical substances 
that are the subject of these SNURs, EPA considered relevant 
information about the toxicity of the chemical substances and potential 
human exposures and environmental releases that may be associated with 
the conditions of use for the substances, in addition to the factors in 
TSCA section 5(a)(2). Note that when the Agency issues an order under 
TSCA section 5(e), TSCA section 5(f)(4) requires that the Agency 
consider whether to promulgate a SNUR for any use not conforming to the 
restrictions of the order or publish a statement describing the reasons 
for not initiating the rulemaking.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements 
for 31 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 SNUR or basis for the TSCA 5(e) Order.
     Information identified by EPA that would help characterize 
the potential health and/or environmental effects of the chemical 
substance in support of a request by the PMN submitter to modify the 
Order, or if a manufacturer or processor is considering submitting a 
SNUN for a significant new use designated by the SNUR. This information 
may include testing required in a TSCA section 5(e) Order to be 
conducted by the PMN submitter, as well as testing not required to be 
conducted but which would also help characterize the potential health 
and/or environmental effects of the PMN substance. Any recommendation 
for information identified by EPA 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 chemical substance. Further, 
any such testing identified by 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. EPA also recognizes that 
whether testing/further information is needed will depend on the 
specific

[[Page 38160]]

exposure and use scenario in the SNUN. EPA encourages all SNUN 
submitters to contact EPA to discuss any potential future testing. See 
Unit VII. for more information.
     CFR citation assigned in the regulatory text section of 
the proposed rule. The regulatory text section of each proposed rule 
specifies the activities that would be designated as significant new 
uses. Certain new uses, including exceedance of production volume 
limits (i.e., limits on manufacture volume) and other uses designated 
in this proposed rule, may be claimed as CBI.
    These proposed rules include 7 PMN substances that are subject to 
Orders issued under TSCA section 5(e)(1)(A), as required by the 
determinations made under TSCA section 5(a)(3)(B). Those Orders require 
protective measures to limit exposures or otherwise mitigate the 
potential unreasonable risk. The proposed SNURs would identify as 
significant new uses any manufacturing, processing, use, distribution 
in commerce, or disposal that does not conform to the restrictions 
imposed by the underlying Orders, consistent with TSCA section 5(f)(4).
    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) 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) 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 40 CFR 
721.63 respirator requirements may request to do so under 40 CFR 
721.30. EPA expects that persons whose 40 CFR 721.30 requests to use 
the NCELs approach for SNURs that 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) Order for the same chemical 
substance.
    These proposed rules also include 24 PMN substances that received 
``not likely to present an unreasonable risk'' determination in TSCA 
section 5(a)(3)(c). However, during the course of these reviews, EPA 
identified concerns for certain health and/or environmental risks if 
the chemicals were not used following the limitations identified by the 
submitters in the notices but the TSCA section 5(a)(3)(C) 
determinations did not deem those uses as reasonably foreseen. The 
proposed SNURs would identify as significant new uses any 
manufacturing, processing, use, distribution in commerce, or disposal 
that does not conform to those same protection measures.
    The chemicals subject to these proposed SNURs are as follows:

PMN Number: P-16-400

    Chemical Name: Alkanes, C11-16-branched and linear.
    CAS Number: 1809170-78-2.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a chemical intermediate, in cured coatings, cleaning fluids, 
metalworking fluids/rolling oils, and in agrochemicals. Based on the 
estimated physical chemical properties of the PMN substance and analogy 
to structurally similar substances, EPA has identified concerns for 
lung effects and dermal irritation if the chemical substance is not 
used following the limitations noted. The conditions of use of the PMN 
substance as described in the PMN include the following protective 
measures:
    1. No manufacture, processing, or use of the PMN substance other 
than for the uses stated in the PMN; and
    2. No manufacture, processing, or use of the PMN substance for 
consumer use.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health effects of the PMN substance may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of irritation 
and pulmonary effects testing would help characterize the potential 
health effects of the PMN substance.
    CFR Citation: 40 CFR 721.11300.

PMN Number: P-17-119

    Chemical Name: Alkyl alkenoic acid, alkoxyalkyl ester, polymer with 
alkyl alkenoate, alkyl alkyl alkenoate and tris alkyl silyl alkyl 
alkenoate (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as a component of 
industrial coatings. Based on the estimated physical chemical 
properties of the PMN substance and test data on the PMN substance, EPA 
has identified concerns for lung effects and irritation to the eyes, 
skins, lung, and mucous membranes if the chemical substance is not used 
following the limitations noted. The conditions of use of the PMN 
substance as described in the PMN include the following protective 
measures:
    1. No domestic manufacture of the PMN substance; and
    2. No manufacture, processing, or use of the PMN substance that 
results in inhalation exposures.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health effects of the PMN substance may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of pulmonary 
effects testing would help characterize the potential health effects of 
the PMN substance.
    CFR Citation: 40 CFR 721.11301.

PMN Number: P-17-191

    Chemical Name: Alkyldiamine, aminoalkyl dimethylaminoalkyl 
dimethyl-, reaction products with propylene oxide (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a polyurethane catalyst. Based on the estimated physical 
chemical properties of the PMN substance and data on analogous 
compounds, EPA has identified concerns for skin, eye, and lung 
corrosion, neurotoxicity, and systemic effects if the chemical 
substance is not used following the limitations noted. The conditions 
of use of the PMN substance as described in the PMN include the 
following protective measure:
     No manufacture, processing, or use of the PMN substance 
that would generate a spray, mist, or aerosol.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.

[[Page 38161]]

    Potentially useful information: EPA has determined that certain 
information about the human health effects of the PMN substance may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of skin 
irritation/corrosion and neurotoxicity testing would help characterize 
the potential health effects of the PMN substance.
    CFR Citation: 40 CFR 721.11302.

PMN Number: P-17-220

    Chemical Name: 2-Oxepanone, reaction products with alkylenediamine-
alkyleneimine polymer, 2-[[(2-alkyl)oxy]alkyl]oxirane and tetrahydro-
2H-pyran-2-one (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as an additive, open, 
non-dispersive use. Based on the estimated physical chemical properties 
of the PMN substance, comparison with structurally analogous chemical 
substances, and Structure Analysis Relationships (SAR) analysis of test 
data on polycationic polymers, EPA has identified hazards for 
irritation to the eye, lung, and mucous membranes, lung effects, and 
aquatic toxicity if the chemical substance is not used following the 
limitations noted. The conditions of use of the PMN substance as 
described in the PMN include the following protective measures:
    1. No domestic manufacture of the PMN substance;
    2. No manufacture or import of the PMN substance other than in 
liquid form; and
    3. No manufacture, processing, or use of the PMN substance other 
than for the confidential use stated in the PMN.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health and environmental effects of the PMN 
substance may be potentially useful if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that the results 
of aquatic toxicity and pulmonary effects testing would help 
characterize the potential health and environmental effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11303.

PMN Numbers: P-17-387 and P-17-388

    Chemical Name: Dicarboxylic acids, polymers with alkanoic acid, 
alkanediol, substituted-alkylalkanoic acid, substituted alkyl 
carbomonocycle, alkanedioic acid, alkanolamine blocked compds with 
alkanolamine (P-17-387 and P-17-388) (generic).
    CAS Numbers: Not available.
    Basis for action: The PMNs state that the generic (non-
confidential) use of the substances will be as paint. Based on the 
estimated physical/chemical properties of the PMN substances and 
available PMN data, EPA has identified developmental and reproductive 
effects, lung toxicity, and nasal and ocular irritation if the chemical 
substances are not used following the limitations noted. The conditions 
of use of the PMN substances as described in the PMNs include the 
following protective measures:
    1. No manufacture (including import) of the PMN substances that 
results in amine counter ions greater than 4% by weight;
    2. No manufacture (including import) of the PMN substances that 
results in isocyanate residuals greater than 0.1% by weight;
    3. No manufacture (including import) of the PMN substances that 
results in a proportion of the acid group greater than 20% by weight; 
and
    4. No manufacture (including import) of the PMN substances that 
results in the average molecular weight smaller than the confidential 
molecular weight specified in the PMNs or proportion of the low 
molecular weight species greater than the confidential values specified 
in the PMNs for the 500 and 1000 dalton species.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health effects of the PMN substances may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of 
developmental/reproductive and pulmonary effects testing would help 
characterize the potential health effects of the PMN substances.
    CFR Citation: 40 CFR 721.11304.

PMN Number: P-17-419

    Chemical name: Unsaturated polycyclic hydrocarbon (generic).
    CAS number: Not available.
    Effective date of TSCA section 5(e) Order: February 6, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that the generic 
(non-confidential) use of the substance will be as a cyclic hydrocarbon 
building block. Based on physical/chemical properties of the PMN 
substance (as described in the New Chemical Program's PBT category at 
64 FR 60194; November 4, 1999) and test data on structurally similar 
substances, the PMN substance is a potentially persistent, 
bioaccumulative, and toxic (PBT) chemical. EPA estimates that the PMN 
substance will persist in the environment more than 2 months and 
estimates a bioaccumulation factor of greater than or equal to 1,000. 
EPA has also identified concern for skin irritation, reproductive and 
developmental toxicity based on analog data and concern for 
sensitization based on Safety Data Sheet (SDS) information. Based on 
SAR analysis of test data on analogous neutral organics, EPA has 
identified concern for aquatic toxicity. The Order was issued under 
5(a)(3)(B)(i) and 5(e)(1)(A)(i), based on a finding that the available 
information is insufficient to permit a reasoned evaluation of the 
human health and environmental effects of the PMN substance. The Order 
was also 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 Order requires:
    1. Submit to EPA certain toxicity testing within 9 months from the 
effective date of the Order.
    2. Submit to EPA certain toxicity testing for within 12 months from 
EPA's direction to proceed with that testing.
    3. Refrain from manufacturing (including import) more than the 
confidential annual production volume limit specified in the Order.
    4. Use of the PMN substance only for the confidential use allowed 
by the Order.
    5. No release of the PMN substance to surface waters.
    6. Use of personal protective equipment to its workers to prevent 
dermal exposure where there is potential for dermal exposure.
    7. Use of a National Institute for Occupational Safety and Health 
(NIOSH) certified respirator with an Assigned Protection Factor (APF) 
of at least 50 where there is a potential for inhalation exposure.
    8. Establishment and use of a hazard communication program, 
including human health precautionary statements on each label and in 
the SDS.

[[Page 38162]]

    The SNUR designates as a ``significant new use'' the absence of 
these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the health and environmental effects of the PMN 
substance may be potentially useful in support of a request by the PMN 
submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this SNUR. The submitter has agreed to perform certain 
acute aquatic toxicity testing within 9 months of the effect of the 
Order, and certain chronic aquatic toxicity testing within 12 months of 
EPA's direction to proceed. The Agency has determined that specific 
target organ toxicity, reproductive and developmental toxicity, 
sensitization, and fate information would help EPA determine the 
potential health effects of the PMN substance. Although the Order does 
not require this information, the Order's restrictions remain in effect 
until the Order is modified or revoked by EPA based on submission of 
this or other relevant information.
    CFR citation: 40 CFR 721.11305.

PMN Numbers: P-18-7 and P-18-8

    Chemical Names: Glycerides, soya mono- and di-, epoxidized, 
acetates (P-18-7) and Glycerides, C16-18 and C18-unsatd. mono- and di-, 
epoxidized, acetates (P-18-8).
    CAS Numbers: 2097734-14-8 (P-18-7) and 2097734-15-9 (P-18-8).
    Basis for action: The PMNs state that the use of the substances 
will be as plasticizers/stabilizers for flexible polyvinyl chloride. 
Based the estimated physical/chemical properties of the PMN substances 
and comparison with structurally analogous chemical substances, EPA has 
identified skin irritation and kidney and liver hazards if the chemical 
substances are not used following the limitations noted. The conditions 
of use of the PMN substances as described in the PMNs include the 
following protective measures:
    1. No manufacture, processing, or use that results in inhalation 
exposures; and
    2. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substances into the waters of the 
United States exceeding a surface water concentration of 9,000 parts 
per billion (ppb).
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human effects of the PMN substances may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of specific 
target organ toxicity and skin irritation testing would help 
characterize the potential health effects of the PMN substances.
    CFR Citations: 40 CFR 721.11306 (P-18-7) and 40 CFR 721.11307 (P-
18-8).

PMN Number: P-18-55

    Chemical Name: Mixed metal oxide (generic).
    CAS Number: Not Available.
    Effective date of TSCA section 5(e) Order: April 2, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that the generic 
use of the PMN substance will be as a catalyst. EPA identified concerns 
for lung effects including cancer, and respiratory and dermal 
sensitization based on the estimated physical/chemical properties, 
available PMN data, and by comparison to structurally analogous 
chemical substances. 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 in the 
absence of sufficient information to permit a reasoned evaluation the 
substance may present an unreasonable risk of injury to human health. 
To protect against these risks, the Order requires:
    1. Use of personal protective equipment where there is a potential 
for dermal exposure;
    2. Use of a NIOSH-certified respirator with an APF of at least 
1,000 where there is a potential for inhalation exposure or compliance 
with a NCEL of 0.04 mg/m\3\ as an 8-hour time-weighted average to 
prevent inhalation exposure;
    3. Use of the PMN substance only for the confidential use allowed 
by the Order; and
    4. Establishment and use of a hazard communication program, 
including human health precautionary statements on each label and in 
the SDS.
    The SNUR designate as a ``significant new use'' the absence of 
these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the health effects of the PMN substance may be 
potentially useful in support of a request by the PMN submitter to 
modify the Order, or if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this SNUR. EPA has also determined that specific pulmonary toxicity and 
sensitization effects testing of the PMN substance would be useful in 
determining the health effects of the PMN substance. Although the Order 
does not require these tests, the Order's restrictions remain in effect 
until the Order is modified or revoked by EPA based on submission of 
this or other relevant information.

    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the health effects of the PMN substance may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of pulmonary 
effects and skin irritation testing would help characterize the 
potential health effects of the PMN substance.
    CFR Citation: 40 CFR 721.11326.

PMN Number: P-19-26

    Chemical Name: Alkanoic acid, compds. with substituted 
carbomonocycle-dialkyl-alkanediamine-halosubstituted heteromonocycle-
polyalkylene glycol polymerdialkanolamine reaction products (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a component in coating resin products that are applied by 
cathodic electrodeposition and as an additive for corrosion protection. 
Based on the estimated physical chemical properties of the PMN 
substance, comparison with structurally analogous chemical substances, 
and Structure Analysis Relationships (SAR) analysis of test data on 
cationic polymers, EPA has identified concerns for irritation, lung 
effects, and aquatic toxicity at concentrations greater than 15 ppb if 
the chemical substance is not used following the limitation noted. The 
conditions of use of the PMN substance as described in the PMN include 
the following protective measures:
    1. No manufacturing (including import), processing, or use that 
results in inhalation exposures to vapor, particulate, mist or 
aerosols; and
    2. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substance exceeding a surface water 
concentration of 15 ppb.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health and environmental effects of the PMN 
substance may be potentially useful if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that the results 
of pulmonary effects, skin irritation, and aquatic toxicity testing 
would help characterize the potential health effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11327.

PMN Number: P-19-27

    Chemical Name: Substituted carbomoncycle, polymer with haloalkyl 
substituted heteromonocycle, dialkyl-alkanediamine and hydro-
hydroxypoly[oxy(alkylalkanediyl)], reaction products with metal oxide 
and dialkanolamine, acetates (salt) (generic).

[[Page 38167]]

    CAS Number: Not available.
    Basis for action: The PMN states that the use of the PMN substance 
will be as an isolated intermediate incorporated as a component in 
coating resin products that are applied by cathodic electrodeposition 
and used as additives for corrosion protection. Based on the estimated 
physical chemical properties of the PMN substance, comparison with 
structurally analogous chemical substances, and Structure Analysis 
Relationships (SAR) analysis of test data on analogous cationic 
polymers, EPA has identified lung effects and aquatic toxicity if the 
chemical substance is not used following the limitations noted. The 
conditions of use of the PMN substance as described in the PMN include 
the following protective measures:
    1. No manufacturing, processing, or use that results in inhalation 
exposures to vapor, particulate, mist or aerosols; and
    2. No manufacture (including import) of an annual production volume 
of the PMN substance greater than 95,600 kg.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health and environmental effects of the PMN 
substance may be potentially useful if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that the results 
of pulmonary effects and aquatic toxicity testing would help

PMN Number: P-19-45

    Chemical Name: Non-metal tetrakis (hydroxyalkyl)-, halide, polymer 
with amide oxidized (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as a component of a 
textile coating. Based on the estimated physical chemical properties of 
the PMN substance and comparison with structurally analogous chemical 
substances, EPA has identified effects concerns for irritation to the 
skin and eyes, skin sensitization, and reproductive and developmental 
toxicity if the chemical substance is not used following the 
limitations noted. The conditions of use of the PMN substance as 
described in the PMN include the following protective measures:
    1. No manufacturing, processing, or use that results in inhalation 
exposures;
    2. No manufacturing that results in unbound formaldehyde residuals 
greater than 0.1%; and
    3. No manufacturing, processing, or use other than the confidential 
use described in the PMN.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health toxicity of the PMN substance may be 
potentially useful if a manufacturer or processor is considering 
submitting a SNUN for a significant new use that would be designated by 
this proposed SNUR. EPA has determined that the results of skin and eye 
irritation, skin sensitization, and developmental toxicity testing 
would help characterize the potential health effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11329.

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are subject to these proposed SNURs, EPA concluded that for 7 
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) Orders requiring the use of 
appropriate exposure controls were negotiated with the PMN/MCAN 
submitters. The SNURs would identify as significant new uses any 
manufacturing, processing, use, distribution in commerce, or disposal 
that does not conform to the restrictions imposed by the underlying 
Orders, consistent with TSCA section 5(f)(4).
    During review of the other 24 chemical substances that are the 
subject of these SNURs and as further discussed in Unit IV, EPA 
identified circumstances different from the intended conditions of use 
identified in the PMNs that raised potential risk concerns. EPA 
determined that deviations from the protective measures identified in 
the submissions could result in changes in the type or form of exposure 
to the chemical substances and/or increased exposures to the chemical 
substances and/or changes in the reasonably anticipated manner and 
methods of manufacturing, processing, distribution in commerce, and 
disposal of the chemical substances, and therefore warranted SNURs. The 
SNURs would identify as significant new uses any manufacturing, 
processing, use, distribution in commerce, or disposal that does not 
conform to the protection measures in the submission.

B. Objectives

    EPA is proposing these SNURs for specific chemical substances which 
have undergone premanufacture review because the Agency wants to 
achieve the following objectives with respect to the significant new 
uses that would be designated in this proposed rule:
     EPA would receive notice of any person's intent to 
manufacture or process a listed chemical substance for the described 
significant new use before that activity begins.
     EPA would be required 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 would be required 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.
    Issuance of a SNUR for a chemical substance does not signify that 
the chemical substance is listed on the TSCA Chemical Substance 
Inventory (TSCA Inventory). Guidance on how to determine if a chemical 
substance is on the TSCA Inventory is available on the internet at 
https://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/.

VI. Applicability of the Proposed 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 proposed 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 proposed 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.

[[Page 38168]]

However, TSCA section 5(e) Orders have been issued for 7 of the 31 
chemical substances, and the PMN submitters are prohibited by the TSCA 
section 5(e) Orders from undertaking activities which would be 
designated as significant new uses. The identities of 25 of the 31 
chemical substances subject to this proposed rule have been claimed as 
confidential (per Sec. Sec.  720.85 and 725.85) for a chemical 
substance covered by this action. 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 proposed rule are ongoing.
    Therefore, EPA designates August 6, 2019 as the cutoff date for 
determining whether the new use is ongoing. The objective of EPA's 
approach is to ensure that a person cannot defeat a SNUR by initiating 
a significant new use before the effective date of the final rule.
    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 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.

VII. 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 and 725.155). 
However, upon review of PMNs and SNUNs, the Agency has the authority to 
require appropriate testing. Unit IV. lists potentially useful 
information identified by EPA that would help characterize the 
potential health and/or environmental effects of the PMN/SNUN substance 
for all of the listed SNURs. EPA recognizes that the 2016 Lautenberg 
Amendments have led to modifications in our approach to testing 
requirements, including an increased consideration of alternatives to 
vertebrate testing. Descriptions of tests/information needs are 
provided for informational purposes only and EPA strongly encourages 
persons, before performing any testing, to consult with the Agency 
pertaining to protocol selection. Pursuant to TSCA section 4(h), which 
pertains to reduction of testing in vertebrate animals, EPA encourages 
consultation with the Agency on the use of alternative test methods and 
strategies (also called New Approach Methodologies, or NAMs), if 
available, to generate the potentially useful information. EPA 
encourages dialogue with Agency representatives to help determine how 
best the submitter can meet both the data needs and the objective of 
TSCA section 4(h). To access the OCSPP test guidelines referenced in 
this document electronically, please go to https://www.epa.gov/ocspp and 
select ``Test Methods and Guidelines.'' The Organisation for Economic 
Co-operation and Development test guidelines are available from the 
OECD Bookshop at https://www.oecdbookshop.org or SourceOECD at https://www.sourceoecd.org.
    The potentially useful information listed in Unit IV. may not be 
the only means of addressing the potential risks of the chemical 
substance. 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.

VIII. SNUN Submissions

    According to 40 CFR 721.1(c), persons submitting a SNUN must comply 
with the same notification requirements and EPA regulatory procedures 
as persons submitting a PMN or MCAN, including submission of test data 
on health and environmental effects as described in 40 CFR 720.50 or 
725.160. 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 (or 40 CFR 725.25 
and Sec.  725.27). E-PMN software is available electronically at https://www.epa.gov/opptintr/newchems.

IX. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers and processors of the chemical 
substances subject to this proposed rule. EPA's complete economic 
analysis is available in the docket under docket ID number EPA-HQ-OPPT-
2019-0359.

X. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed rule would establish SNURs for several new chemical 
substances that were the subject of PMNs and TSCA section 5(e) 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.
    The information collection requirements related to this proposed 
rule 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, 
Regulatory Support Division, Office of Mission Support (2822T), 
Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington, 
DC 20460-0001. Please remember to include the OMB control number in any 
correspondence,

[[Page 38169]]

but do not submit any completed forms to this address.

C. Regulatory Flexibility Act (RFA)

    Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA) 
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation 
of this proposed SNUR would not have a significant adverse economic 
impact on a substantial number of small entities. The requirement to 
submit a SNUN applies to any person (including small or large entities) 
who intends to engage in any activity described in the final rule as a 
``significant new use.'' Because these uses are ``new,'' based on all 
information currently available to EPA, it appears that no small or 
large entities presently engage in such activities. A SNUR requires 
that any person who intends to engage in such activity in the future 
must first notify EPA by submitting a SNUN. Although some small 
entities may decide to pursue a significant new use in the future, EPA 
cannot presently determine how many, if any, there may be. However, 
EPA's experience to date is that, in response to the promulgation of 
SNURs covering over 1,000 chemicals, the Agency receives only a small 
number of notices per year. For example, the number of SNUNs received 
was seven in Federal fiscal year (FY) 2013, 13 in FY2014, six in 
FY2015, 10 in FY2016, 14 in FY2017, and 18 in FY2018 and only a 
fraction of these were from small businesses. In addition, the Agency 
currently offers relief to qualifying small businesses by reducing the 
SNUN submission fee from $16,000 to $2,800. This lower fee reduces the 
total reporting and recordkeeping of cost of submitting a SNUN to about 
$10,116 for qualifying small firms. Therefore, the potential economic 
impacts of complying with this proposed SNUR are not expected to be 
significant or adversely impact a substantial number of small entities. 
In a SNUR that published in the Federal Register of June 2, 1997 (62 FR 
29684) (FRL-5597-1), the Agency presented its general determination 
that final SNURs are not expected to have a significant economic impact 
on a substantial number of small entities, which was provided to the 
Chief Counsel for Advocacy of the Small Business Administration.

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 proposed rule would 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 11632

    This proposed rule would 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 proposed rule would not have Tribal implications because it is 
not expected to have substantial direct effects on Indian Tribes. This 
proposed rule would not significantly nor uniquely affect the 
communities of Indian Tribal governments, nor would 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 proposed rule 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 proposed rule 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 proposed rule is not expected to affect energy supply, 
distribution, or use and because this proposed rule is not a 
significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    In addition, since this proposed rule would 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 proposed rule 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).
