Significant New Use Rules on Certain Chemical Substances

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 28 chemical substances which
were the subject of premanufacture notices (PMNs). The chemical
substances are subject to Orders issued by EPA pursuant to section 5(e)
of TSCA. This action would require persons who intend to manufacture
(defined by statute to include import) or process any of these 28
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 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: Comments must be received on or before May 3, 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 April
18, 2019 are subject to the export notification provisions of TSCA
section 12(b) (15 U.S.C. 2611(b)) (see Sec.  721.20), and must comply
with the export notification requirements in 40 CFR part 707, subpart
D.

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 proposing these SNURs under TSCA section 5(a)(2) for
chemical substances that were the subject of PMNs and are subject to
Orders issued by EPA pursuant to section 5(e) of TSCA. 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 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 proposed 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)
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 rule, recordkeeping
requirements, and exemptions to reporting requirements. Provisions
relating to user fees appear at 40 CFR part 700. According 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). In particular, these requirements include the
information submission requirements of TSCA section 5(b) and 5(d)(1),
the exemptions authorized by TSCA section 5(h)(1), (h)(2), (h)(3), and
(h)(5), and the regulations at 40 CFR part 720. Once EPA receives a
SNUN, EPA must either determine that the significant new use is not
likely to present an unreasonable risk of injury or take such
regulatory action as is associated with an alternative determination
before the manufacture or processing for the significant new use can
commence. If EPA determines that the significant new use is not likely
to present an unreasonable risk, EPA is required under TSCA section
5(g) to make public, and submit for publication in the Federal
Register, a statement of EPA's findings.

III. Significant New Use Determination

    Section 5(a)(2) of TSCA states that EPA's determination that a use
of a chemical substance is a significant new use must be made after
consideration of all relevant factors, including:
     The projected volume of manufacturing and processing of a
chemical substance.
     The extent to which a use changes the type or form of
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and
duration of exposure of human beings or the environment to a chemical
substance.
     The reasonably anticipated manner and methods of
manufacturing, processing, distribution in commerce, and disposal of a
chemical substance.
    In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorizes EPA to consider any other relevant factors.
    To determine what would constitute a significant new use for the 28
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 of the substances, in the context
of the four bulleted TSCA section 5(a)(2) factors listed in this unit.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements
for 28 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 TSCA section 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 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 28 PMN substances that are subject to Orders issued under TSCA
section 5(e)(1)(A). Each Order is based on one or more of the findings
in TSCA section 5(a)(3)(B): There is insufficient information to permit
a reasoned evaluation; in the absence of sufficient information to
permit a reasoned evaluation, the activities associated with the PMN
substances may present unreasonable risk to health or the environment;
the substance is or will be produced in substantial quantities, and
enters or may reasonably be anticipated to enter the environment in
substantial quantities or there is or may be significant (substantial)
human exposure to the substance. 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 Sec.  721.63 respirator requirements may request to do so under
Sec.  721.30. EPA expects that persons whose Sec.  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.

PMN Numbers: P-15-353 and P-15-433

    Chemical Names: Fatty acids, C16 and C18-unsaturated, methyl
esters, chlorinated (P-15-353) and chlorinated complex esters (generic)
(P-15-433).
    CAS Numbers: 1642303-17-0 (P-15-353) and not available (P-15-433).
    Effective date of TSCA section 5(e) Order: July 25, 2018.
    Basis for TSCA section 5(e) Order: The PMNs state that the generic
(non-confidential) use of the PMN substances will be as lubricant
additives. Based on submitted analogue data, EPA has identified concern
for irritation. Based on the physical/chemical properties of the PMN
substances (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 substances are potentially persistent,
bioaccumulative, and toxic (PBT) chemicals. EPA estimates that the PMN
substances will persist in the environment for more than two months and
estimates a bioaccumulation factor of greater than or equal to 1,000.
The Order was issued under TSCA section 5(a)(3)(B)(ii)(I) based on a
finding that in the absence of sufficient information to permit a
reasoned evaluation, the substances may present an unreasonable risk of
injury to the environment. The Order was also issued under TSCA
sections 5(a)(3)(B)(ii)(II) and 5(e)(1)(A)(ii)(II), based on a finding
that the substances are or will be produced in substantial quantities
and that the substances either enter or may reasonably be anticipated
to enter the environment in substantial quantities, or there is or may
be significant (or substantial) human exposure to the substances.
    To protect against these risks, the Order requires:
    1. Submission to EPA of certain testing before exceeding the three-
year time limit specified in the Order; and
    2. Use of the PMN substances only for the confidential uses
specified in the Order.
    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 fate and environmental effects of the PMN
substances may be potentially useful to characterize the effects of the
PMN substances 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
proposed SNUR. The submitter has agreed not to manufacture the PMN
substances beyond three years without performing a specific
biodegradation study and an ecotoxicity testing scheme for P-15-353 to
determine the rate of loss of the parent PMN substances and formation
and identification of degradation products, and to assess their
toxicity.
    CFR citation: 40 CFR 721.11221 (P-15-353) and 40 CFR 721.11222 (P-
15-433).

PMN Number: P-16-186

    Chemical Name: Sodium branched chain alkyl hydroxyl and branched
chain alkenyl sulfonates (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: June 26, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the generic
(non-confidential) use of the substance will be as a surfactant. EPA
identified concern for lung effects based on surfactant activity if
respirable particles are inhaled and concern for irritation based on
potential surfactant activity to all exposed tissues. EPA also
identified concern for developmental toxicity based on data provided
for an analogue. The Order was issued under TSCA sections
5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 and the environment. To protect against these risks, the
Order requires:
    1. Use of personal protective equipment to prevent dermal exposure
where there is a potential for dermal exposure;
    2. Refraining from modifying the manufacture, processing or use of
the PMN substance in a manner that results in inhalation exposure to
vapor, dust, spray, mist or aerosol;
    3. Use of the PMN substance only for the confidential use specified
in the Order; and
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and
Safety Data Sheet (SDS).
    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 to characterize the effects of the PMN 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 that would be designated by this proposed SNUR. EPA
has also determined that the results of specific pulmonary toxicity
testing would help characterize the potential health effects of the PMN
substance. Although the Order does not require this test, the Order's
restrictions on manufacture, processing, distribution in commerce, and
use of the PMN substance will 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 721.11223.

PMN Number: P-16-207

    Chemical Name: Spiro tetrafluoroborate (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: August 6, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the use of
the substance will be as an additive for an electrolyte solution. Based
on physical/chemical properties and analysis of test data on the PMN
substance, EPA has identified concern for developmental neurotoxicity,
effects to the bladder, liver, kidney, thymus, stomach, thyroid, and
blood. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and
5(e)(I)(A)(ii)(I) based on a finding that in the absence of sufficient
information to permit a reasoned evaluation, the substances may present
an unreasonable

risk of injury to human health or the environment. To protect against
these risks, the Order requires:
    1. Submission to EPA of certain toxicity testing before exceeding
the aggregate volumes specified in the Order;
    2. Use of personal protective equipment where there is potential
for dermal exposure;
    3. Use of a National Institute of Occupational Safety and Health
(NIOSH)-certified respirator with an assigned protection factor (APF)
of at least 1000 (where there is potential for inhalation exposure) or
compliance with a NCEL of 0.2 mg/m\3\ as an 8-hour time-weighted
average;
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS;
    5. Refraining from domestic manufacture in the United States (i.e.,
import only); and
    6. Use of the PMN substance only for the confidential use specified
in the Order.
    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 environmental and 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. The submitter has agreed not to exceed a certain production
volume limit without performing specific reproductive toxicity testing
and acute aquatic toxicity testing.
    CFR citation: 40 CFR 721.11224.

PMN Numbers: P-16-246 and P-16-516

    Chemical Names: 2-pyridinecarboxylic acid, 6-(4-chloro-2-fluoro-3-
methoxyphenyl)-4,5-difluoro-, phenylmethyl ester (P-16-246) and 2-
pyridinecarboxylic acid, 4-amino-6-(4-chloro-2-fluoro-3-methoxyphenyl)-
5-fluoro-, phenylmethyl ester, hydrochloride (1:1) (P-16-516).
    CAS Numbers: 1391033-38-7 (P-16-246) and not available (P-16-516).
    Effective date of TSCA section 5(e) Order: May 21, 2017.
    Basis for TSCA section 5(e) Order: The PMNs state that the generic
(non-confidential) use of the substances will be as chemical
intermediates. Based on analysis of test data on analogous esters, EPA
has identified concerns for carcinogenicity, developmental/reproductive
effects, systemic toxicity, sensitization, and aquatic/terrestrial
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 in the absence of
sufficient information to permit a reasoned evaluation, the substances
may present an unreasonable risk of injury human health and the
environment. To protect against these risks, the Order requires:
    1. Submission of certain toxicity testing on the PMN substances
prior to exceeding the time limits specified in the Order;
    2. Use of personal protective equipment where there is a potential
for dermal exposure;
    3. Use of a NIOSH-certified respirator with an APF of at least 50
where there is a potential for inhalation exposure;
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS;
    5. Use of the PMN substances only for the confidential uses
specified in the Order; and
    6. No release of the PMN substances to surface waters.
    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 substances 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 proposed SNUR. The submitter has agreed not to exceed certain time
limits without performing sensitization, mutagenicity, reproductive/
developmental, and carcinogenicity effects testing. EPA has also
determined that the results of acute aquatic toxicity testing would
help characterize the potential environmental effects of the PMN
substances. Although the Order does not require these tests, 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 relevant
information.
    CFR citations: 40 CFR 721.11225 (P-16-246) and 40 CFR 721.11226 (P-
16-516).

PMN Numbers: P-16-271 and P-16-450

    Chemical Name: 1,2,4-Benzenetricarboxylic acid, 1,2,4-trinonyl
ester.
    CAS Number: 1817723-10-6.
    Effective date of TSCA section 5(e) Orders: June 22, 2018.
    Basis for TSCA section 5(e) Orders: The PMNs state that the use of
the substance will be used as a plasticizer for wire and cable
insulation. EPA identified concerns for the PMN substance as a mild
skin irritant as well as for blood, developmental, systemic, maternal,
and male reproductive toxicity based on analysis of test data on
analogous trimellitate esters. The Order was issued under TSCA sections
5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, 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 and the environment. The Order was also issued under TSCA
sections 5(a)(3)(B)(ii)(II) and 5(e)(1)(A)(ii)(II), based on a finding
that the substance is or will be produced in substantial quantities and
that the substance either enters or may reasonably be anticipated to
enter the environment in substantial quantities, or there is or may be
significant (or substantial) human exposure to the substance. To
protect against these risks, the Orders require:
    1. Submit to EPA certain toxicity testing before manufacturing
(including import) a total of 1,750,000 kilograms (in each Order) of
the PMN substance;
    2. Submit to EPA additional toxicity testing which will be
determined upon EPA review of the initial toxicity testing results;
    3. Use of personal protective equipment to prevent dermal exposure
where there is a potential for dermal exposure;
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS and worker training in accordance with the Hazard Communication
section of the Orders;
    5. Refraining from domestic manufacture in the United States (i.e.,
import only); and
    6. Use of the PMN substance only as plasticizer for wire and cable
insulation.
    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 and environmental effects of the PMN
substance may be potentially useful in support of a request by the PMN
submitters 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 proposed SNUR. The submitters have agreed not to
exceed certain production volume limits without performing
reproductive/

developmental toxicity tests and aquatic sediment toxicity tests.
    CFR citation: 40 CFR 721.11227.

PMN Number: P-16-388

    Chemical Name: Aliphatic polyamines, polymers with bisphenol A and
epichlorohydrin (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: July 23, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the generic
(non-confidential) use of the substance will be as a hardener for epoxy
coating. Based on the high percentage of amines and a high pH when in
liquid formulation, EPA has identified concern for irritation to the
eyes, skin, mucous membranes, and lungs. The Order was issued under
TSCA sections 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 effects of the PMN substances. To
protect against these risks, the Order requires:
    1. Use of the PMN substance only for the confidential use specified
in the Order;
    2. Use of personal protective equipment to prevent dermal exposure
where there is potential for dermal exposure;
    3. No use of the PMN substance in a consumer product; and
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS.
    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 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 proposed SNUR. EPA has also determined that the results of skin
irritation and skin sensitization toxicity testing would help
characterize the potential health effects of the PMN substance.
Although the Order does not require these tests, the Order's
restrictions on manufacture, distribution in commerce, and use of the
PMN substance will remain in effect until the Order is modified or
revoked by EPA based on submission of this or relevant information.
    CFR citation: 40 CFR 721.11228.

PMN Numbers: P-16-489, P-16-490, and P-16-491

    Chemical Name: Epoxy-amine adduct, methanesulfonates (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: June 11, 2018.
    Basis for TSCA section 5(e) Order: The PMNs state that the generic
(non-confidential) use of the substances will be open, non-dispersive.
Based on physical/chemical properties of the PMN substances, EPA has
identified concern for lung toxicity. Ecotoxicity hazards were
identified based on structural analysis relationship (``SAR'')
predictions for polycationic polymers. 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 substances may present an unreasonable risk of injury
to human health and the environment. To protect against these risks,
the Order requires:
    1. Refrain from manufacture, processing, or use of the PMN
substances that result in inhalation exposure to vapor, mist, or
aerosols;
    2. Refrain from manufacture, processing, or use of the PMN
substances for consumer use;
    3. No release of the PMN substances from manufacturing, processing,
or use resulting in surface water concentrations that exceed 208 parts
per billion (ppb); and
    4. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS.
    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 physical/chemical properties, environmental and
health effects of the PMN substances may be potentially useful to
characterize the effects of the PMN substances 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 proposed SNUR. EPA has also determined
that the results of certain physical/chemical properties, acute aquatic
toxicity testing, and pulmonary effects testing would help characterize
the potential health effects of the PMN substances. Although the Order
does not require these tests, the Order's restrictions on manufacture,
distribution in commerce, and use of these PMN substances will remain
in effect until the Order is modified or revoked by EPA based on
submission of this or relevant information.

risk of injury to human health and the environment. To protect against
these risks, the Order requires refraining from manufacturing (which
includes import), processing or using the PMN substance with particle
size less than 50 microns.
    The proposed SNUR would designate as a ``significant new use'' the
absence of this protective measure.
    Potentially useful information: EPA has determined that certain
information about 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

this proposed SNUR. EPA has also determined that the results of
specific pulmonary toxicity testing would help characterize the
potential 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.

    CAS Number: 94-49-5.
    Effective date of TSCA section 5(e) Order: July 31, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the use of
the substance will be as a phlegmatizer (stabilizer for compounds
susceptible to detonation) for peroxides for use with polyester and
vinyl ester resins as well as with curable unsaturated polyester and
methacrylic resins. Based on test data on the PMN substance, and
analysis of test data on analogous chemicals, EPA has identified
concerns for blood, liver, and kidney toxicity, neurotoxicity,
immunotoxicity, and reproductive and developmental toxicity, and
ecotoxicity. The Order was issued under TSCA sections 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 health effects of
the PMN substance. The Order was also issued under TSCA sections

potential health and environmental effects of the PMN substance.
Although the Order does not require these tests, the Order's
restrictions on manufacture, processing, distribution in commerce, and
use of the PMN substance will remain in effect until the Order is
modified or revoked by EPA based on submission of this or relevant
information.
    CFR citation: 40 CFR 721.11243.

PMN Number: P-18-51

    Chemical Name: Alkenoic acid, reaction products with polymers with
isocyanatoalkane and substituted alkanoic acid, substituted
monoacrylate alkanoate-blocked (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: July 30, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the use of
the substance will be as a waterborne ultraviolet curable coating resin
binder for inkjet, ink, or overprint varnish. Based on physical/
chemical properties, available data on the PMN substance and comparison
to structurally analogous acrylates, EPA has identified concern for
developmental toxicity, sensitization, irritation, corrosion, and eye
damage. The Order was issued under TSCA section 5(a)(3)(B)(ii)(I) based
on a finding that in the absence of sufficient information to permit a
reasoned evaluation, the substances may present an unreasonable risk of
injury to human health or the environment. To protect against these
risks, the Order requires:
    1. Refraining from domestic manufacture in the United States (i.e.,
import only);
    2. Only use the PMN substance as a waterborne ultraviolet curable
coating resin binder for inkjet, ink, or overprint varnish;
    3. Import the PMN substance with no greater than 24% branched alkyl
acid moiety content;
    4. Import the PMN substance with no greater than 0.1% isocyanate
content;
    5. Use of personal protective equipment where there is potential
for dermal exposure;
    6. Use of a NIOSH-certified respirator with an APF of at least 1000
where there is a potential for inhalation exposure;
    7. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS; and
    8. No release of the PMN substance resulting in surface water
concentrations that exceed 660 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 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 proposed SNUR. EPA has also determined that the
results of water solubility, acute and chronic aquatic toxicity,
developmental toxicity, and sensitization testing would help
characterize the potential health and environmental effects of the PMN
substance. Although the Order does not require these tests, the Order's
restrictions on manufacture, processing, distribution in commerce, and
use of the PMN substance will remain in effect until the Order is
modified or revoked by EPA based on submission of this or relevant
information.
    CFR citation: 40 CFR 721.11244.

PMN Numbers: P-18-71 and P-18-79

    Chemical Names: Aromatic dicarboxylic acid, compd. with alkane
diamines, polymer with alkane diamine and alkane dicarboxylic acid
(generic) (P-18-71) and Aromatic dicarboxylic acid, compd. with alkyl
diamines, homopolymer (generic) (P-18-79).
    CAS Numbers: Not available.
    Effective date of TSCA section 5(e) Order: July 6, 2018.
    Basis for TSCA section 5(e) Order: The PMNs state that the generic
(non-confidential) use of the substances will be as engineering
thermoplastic. EPA identified concern for lung effects if the PMN
substances are made with a particle size less than 10 microns based on
analogy to similar poorly soluble particles. The Order was issued under
TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(l)(A)(ii)(I) of TSCA, based on
a finding that in the absence of sufficient information to permit a
reasoned evaluation, the substances may present an unreasonable risk of
injury to human health and the environment. To protect against this
risk, the Order requires manufacture of the PMN substances with a
particle size greater than 10 microns. The proposed SNUR would
designate as a ``significant new use'' the absence of this protective
measure.
    Potentially useful information: EPA has determined that certain
information about the health effects of the PMN substances would 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 proposed SNUR. EPA has also determined that the results of
pulmonary effects testing would help characterize the potential health
effects of the PMN substance. Although the Order does not require this
test, the Order's restrictions on manufacture, processing, distribution
in commerce, and use of the PMN substances will remain in effect until
the Order is modified or revoked by EPA based on submission of this or
relevant information.
    CFR citations: 40 CFR 721.11245 (P-18-71) and 40 CFR 721.11246 (P-
18-79).

PMN Number: P-18-82

    Chemical Name: Aspartic acid, tallow modified diester (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: July 3, 2018.
    Basis for TSCA section 5(e) order: The PMN states that the use of
the substance will be as an intermediate used in the manufacture of a
surface-active agent. Based on test data available for an analogue, EPA
has identified concerns for irritation, blood effects, neurotoxicity
and surfactant effects in the lungs based on analogue data. Based on
SAR analysis of anionic surfactants, EPA predicts toxicity to aquatic
organisms may occur at concentrations that exceed 1 ppb. 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 substances may present an
unreasonable risk of injury to human health and the environment. To
protect against these risks, the Order requires:
    1. Manufacture, process and use of the PMN substance only as stated
in the PMN submission;
    2. Use only as an intermediate;
    3. Refraining from modifying the manufacture, processing or use in
a manner resulting in inhalation exposure;
    4. Use of personal protective equipment to prevent dermal exposure
(where there is potential for dermal exposure);
    5. Establishment and use of a hazard communication program,
including human health precautionary statement on each label and in the
SDS;
    6. That PMN residuals will be recycled back into the process as
stated in the PMN; and
    7. No release of the PMN substance resulting in surface water
concentrations that exceed 1 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 environmental and 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 proposed SNUR. EPA has also determined that the
results of acute aquatic toxicity, pulmonary effects, and specific
target organ toxicity testing would help characterize the potential
environmental and health effects of the PMN substance. Although the
Order does not require these tests, the Order's restrictions on
manufacture, processing, distribution in commerce, use, and disposal of
the PMN substance will remain in effect until the Order is modified or
revoked by EPA based on submission of this or relevant information.
    CFR citation: 40 CFR 721.11247.

PMN Number: P-18-130

    Chemical Name: Substituted alkanediol, polymer with
heteromonocycles, alkenoate, metal complexes (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: July 26, 2018.
    Basis for TSCA section 5(e) Order: The PMN states that the use of
the substance will be as an adhesion promoter for industrial
application. Based on analysis of analogous acrylates, and physical/
chemical properties, EPA has identified concerns for mutagenicity,
oncogenicity, developmental toxicity, sensitization, irritation, and
liver and kidney 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 in the
absence of sufficient information to permit a reasoned evaluation, the
substance may present an unreasonable risk of injury to health and the
environment. 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 50
to mitigate inhalation and 1000 where the PMN substance has a use
involving spray application;
    3. Refraining from domestic manufacture in the United States (i.e.,
import only);

    4. Use of the PMN substance only as an adhesion promoter for
industrial applications; and
    5. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS.
    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 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 proposed SNUR. EPA has also determined that the results of
absorption, distribution, metabolism, elimination, genotoxicity, and
sensitization testing would help characterize the potential health
effects of the PMN substance. Although the Order does not require these
tests, the Order's restrictions on manufacture, distribution in
commerce, and use of the PMN substance will remain in effect until the
Order is modified or revoked by EPA based on submission of this or
relevant information.
    CFR citation: 40 CFR 721.11248.

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 all 28
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 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).

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 about the significant new uses
designated in this 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 have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins manufacturing or
processing a listed chemical substance for the described significant
new use.
     EPA would be able to either determine that the prospective
manufacture or processing is not likely to present an unreasonable
risk, or to take necessary regulatory action associated with any other
determination, before the described significant new use of the chemical
substance occurs.
     EPA 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).
    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
http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

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. However, TSCA section 5(e) Orders have been
issued for all of the 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 23
of the 28 chemical substances subject to this proposed rule have been
claimed as confidential (per Sec. Sec.  720.25) 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 March 19, 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. In
developing this proposed rule, EPA has recognized that, given EPA's
general practice of posting proposed rules on its website a week or
more in advance of Federal Register publication, this objective could
be thwarted even before Federal Register publication of the proposed
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). 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 http://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
http://www.oecdbookshop.org or SourceOECD at http://www.sourceoecd.org.
    In certain of the TSCA section 5(e) Orders for the chemical
substances that would be regulated under this proposed rule, EPA has
established production 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 specified tests that would permit a reasoned evaluation
of the potential risks posed by these chemical substances. Listings of
the tests specified in the TSCA section 5(e) Orders are included in
Unit IV. The proposed SNURs contain the same production limits as the
TSCA section 5(e) 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 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.
    Any request by EPA for the testing described in the Orders was made
based on EPA's consideration of available screening-level data, if any,
as well as other available information on appropriate testing for the
PMN substances. Further, any such testing/information request on the
part of EPA that includes testing on vertebrates was made after
consideration of available toxicity information, computational
toxicology and bioinformatics, and high-throughput screening methods
and their prediction models.
    The 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.
     Information on risks posed by the chemical substances
compared to risks posed by potential substitutes.

VIII. SNUN Submissions

    According to Sec.  721.1(c), persons submitting a SNUN must comply
with the same notification requirements and EPA regulatory procedures
as persons submitting a PMN, including submission of test data on
health and environmental effects as described in 40 CFR 720.50. SNUNs
must be submitted on EPA Form No. 7710-25, generated using e-PMN
software, and submitted to the Agency in accordance with the procedures
set forth in 40 CFR 720.40 and Sec.  721.25. E-PMN software is
available electronically at http://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-
2018-0650.

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,
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)

    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, and 14 in FY2017,
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 13132

    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).
