Significant New Use Rules on Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is promulgating significant new use rules (SNURs) under 
the Toxic Substances Control Act (TSCA) for 17 chemical substances 
which were the subject of premanufacture notices (PMNs). Two of these 
chemical substances are subject to TSCA consent orders issued by EPA. 
This action requires persons who intend to manufacture, import, or 
process any of these 17 chemical substances for an activity that is 
designated as a significant new use by this rule to notify EPA at least 
90 days before commencing that activity. The required notification will 
provide EPA with the opportunity to evaluate the intended use and, if 
necessary, to prohibit or limit that activity before it occurs.

DATES: This rule is effective on June 4, 2012. For purposes of judicial 
review, this rule shall be promulgated at 1 p.m. (e.s.t.) on April 18, 
2012.
    Written adverse or critical comments, or notice of intent to submit 
adverse or critical comments, on one or more of these SNURs must be 
received on or before May 4, 2012 (see Unit VI. of the SUPPLEMENTARY 
INFORMATION).
    For additional information on related reporting requirement dates, 
see Units I.A., VI., and VII. of the SUPPLEMENTARY INFORMATION.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
import, process, or use the chemical substances contained in this rule. 
Potentially affected entities may include, but are not limited to:
     Manufacturers, importers, or processors of one or more 
subject chemical substances (NAICS codes 325 and 324110), e.g., 
chemical manufacturing and petroleum refineries.
    This listing is not intended to be exhaustive, but rather provides 
a guide for readers regarding entities likely to be affected by this 
action. Other types of entities not listed in this unit could also be 
affected. The North American Industrial Classification System (NAICS) 
codes have been provided to assist you and others in determining 
whether this action might apply to certain entities. To determine 
whether you or your business may be affected by this action, you should 
carefully examine the applicability provisions in Sec.  721.5. If you 
have any questions regarding the applicability of this action to a 
particular entity, consult the technical person listed under FOR 
FURTHER INFORMATION CONTACT.
    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 these SNURs must certify 
their compliance with the SNUR requirements. The EPA policy in support 
of import certification appears at 40 CFR part 707, subpart B. In 
addition, any persons who export or intend to export a chemical 
substance that is the subject of this rule are subject to the export 
notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see 
Sec.  [emsp14]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 submitting comments,

II. Background

A. What action is the agency taking?

    EPA is promulgating these SNURs using direct final procedures. 
These SNURs will require persons to notify EPA at least 90 days before 
commencing the manufacture, import, or processing of a chemical 
substance for any activity designated by these SNURs as a significant 
new use. Receipt of such notices allows EPA to assess risks that may be 
presented by the intended uses and, if appropriate, to regulate the 
proposed use before it occurs. Additional rationale and background to 
these rules are more fully set out in the preamble to EPA's first 
direct final SNUR published in the Federal Register issue of April 24, 
1990 (55 FR 17376) (April 24, 1990 SNUR). 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, import, or process the 
chemical substance for that use. Persons who must report are described 
in Sec.  [emsp14]721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to the rule, recordkeeping 
requirements, exemptions to reporting requirements, and applicability 
of the rule to uses occurring before the effective date of the rule. 
Provisions relating to user fees appear at 40 CFR part 700. According 
to Sec.  [emsp14]721.1(c), persons subject to these SNURs must comply 
with the same notice 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 sections 
5(h)(1), 5(h)(2), 5(h)(3), and 5(h)(5), and the regulations at 40 CFR 
part 720. Once EPA receives a SNUN, EPA may take regulatory action 
under TSCA section 5(e), 5(f), 6, or 7 to control the activities for 
which it has received the SNUN. If EPA does not take action, EPA is 
required under TSCA section 5(g) to explain in the Federal Register its 
reasons for not taking action.

III. Significant New Use Determination

    Section 5(a)(2) of TSCA states that EPA's determination that a use 
of a chemical substance is a significant new use must be made after 
consideration of all relevant factors, including:
     The projected volume of manufacturing and processing of a 
chemical substance.
     The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
     The reasonably anticipated manner and methods of 
manufacturing, processing, distribution in commerce, and disposal of a 
chemical substance.
    In addition to these factors enumerated in TSCA section 5(a)(2), 
the statute authorized EPA to consider any other relevant factors.
    To determine what would constitute a significant new use for the 17 
chemical substances that are the subject of these SNURs, EPA considered 
relevant information about the toxicity of the chemical substances, 
likely human exposures and environmental releases associated with 
possible uses, and the four bulleted TSCA section 5(a)(2) factors 
listed in this unit.

IV. Substances Subject to This Rule

    EPA is establishing significant new use and recordkeeping 
requirements for 17 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) number (if assigned for 
non-confidential chemical identities).
     Basis for the TSCA section 5(e) consent order or, for non-
section 5(e) SNURs (i.e., SNURs without TSCA section 5(e) consent 
orders), the basis for the SNUR.
     Toxicity concerns.
     Tests recommended by EPA to provide sufficient information 
to evaluate the chemical substance (see Unit VIII. for more 
information).
     CFR citation assigned in the regulatory text section of 
this rule.
    The regulatory text section of this rule specifies the activities 
designated as significant new uses. Certain new uses, including 
production volume limits (i.e., limits on manufacture and importation 
volume) and other uses designated in this rule, may be claimed as CBI. 
Unit IX. discusses a procedure companies may use to ascertain whether a 
proposed use constitutes a significant new use.
    This rule includes two PMN substances (P-10-486 and P-10-487) that 
are subject to ``risk-based'' consent orders under TSCA section 
5(e)(1)(A)(ii)(I) in which EPA determined that activities associated 
with the PMN substances may present unreasonable risk to human health 
or the environment. Those consent orders require protective measures to 
limit exposures or otherwise mitigate the potential unreasonable risk. 
The so-called ``5(e) SNURs'' on these PMN substances are promulgated 
pursuant to Sec.  [emsp14]721.160, and are based on and consistent with 
the provisions in the underlying consent orders. The 5(e) SNURs 
designate as a ``significant new use'' the absence of the protective 
measures required in the corresponding consent orders.
    This rule also includes SNURs on 15 PMN substances (P-09-248, P-11-
33, P-11-34, P-11-188, P-11-316, P-11-333, P-11-424, P-11-511, P-11-
546, P-11-578, P-11-580, P-11-591, P-11-608, P-11-637, and P-11-662) 
that are not subject to consent orders under TSCA section 5(e). In 
these cases, for a variety of reasons, EPA did not find that the use 
scenario described in the PMN triggered the determinations set forth 
under TSCA section 5(e). However, EPA does believe that certain changes 
from the use scenario described in the PMN could result in increased 
exposures, thereby constituting a ``significant new use.'' These so-
called ``non-5(e) SNURs'' are promulgated pursuant to Sec.  
[emsp14]721.170. EPA has determined that every activity designated as a 
``significant new use'' in all non-5(e) SNURs issued under Sec.  
[emsp14]721.170 satisfies the two requirements stipulated in Sec.  
721.170(c)(2), i.e., these significant new use activities, ``(i) are 
different from those described in the premanufacture notice for the 
substance, including any amendments, deletions, and additions of 
activities to the premanufacture notice, and (ii) may be accompanied by 
changes in exposure or release levels that are significant in relation 
to the health or environmental concerns identified'' for the PMN 
substance.

[[Page 20299]]

PMN Number P-09-248

    Chemical name: Ethyleneamine polyphosphates (generic).
    CAS number: Not available.
    Basis for action: The PMN states that the use of the substance will 
be as a flame retardant added to polymers. Based on test data on the 
PMN substance, EPA predicts toxicity to aquatic organisms may occur if 
releases of the PMN substance to surface water from uses other than 
described in the PMN exceed the releases expected from the use 
described in the PMN. For the described use in the PMN, significant 
environmental releases are not expected. Therefore, EPA has not 
determined that the proposed manufacturing, processing, or use of the 
substance may present an unreasonable risk. EPA has determined, 
however, that any use of the substance other than as described in the 
PMN may cause significant adverse environmental effects. Based on this 
information, the PMN substance meets the concern criteria at Sec.  
721.170(b)(4)(i).
    Recommended testing: EPA has determined that the results of a fish 
early-life stage toxicity test (OPPTS Test Guideline 850.1400) and a 
daphnid chronic toxicity test (OPPTS Test Guideline 850.1300) would 
help characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10282.

PMN Numbers P-10-486 and P-10-487

    Chemical names: (P-10-486) Poly[oxy(methyl-1,2-ethanediyl)], 
.alpha.-sulfo-.omega.-hydroxy-, C12-13-branched and linear alkyl 
ethers, sodium salts and (P-10-487) Poly[oxy(methyl-1,2-ethanediyl)], 
.alpha.-sulfo-.omega.-hydroxy-, C14-15-branched and linear alkyl 
ethers, sodium salts.
    CAS numbers: (P-10-486) 958238-81-8 and (P-10-487) 958238-82-9.
    Effective date of TSCA section 5(e) consent order: July 22, 2011.
    Basis for TSCA section 5(e) consent order: The PMNs state that the 
use of the substances will be for downhole injection for enhanced oil 
recovery. The order was issued under TSCA sections 5(e)(1)(A)(i), 
(e)(1)(A)(ii)(I), and (e)(1)(A)(ii)(II) based on a finding that these 
substances may present an unreasonable risk of injury to the 
environment and will be produced in substantial quantities and may 
reasonably be anticipated to enter the environment in substantial 
quantities. To protect against the risk, the order requires certain 
hazard communication requirements, specific disposal requirements for 
processing and use, and prohibits releases from manufacture of the PMN 
substances resulting in surface water concentrations exceeding 28 parts 
per billion (ppb) for P-10-486 and 4 ppb for P-10-487. The SNUR 
designates as a ``significant new use'' the absence of these protective 
measures.
    Toxicity concern: Based on ecological structure activity 
relationship (EcoSAR) analysis of test data on analogous anionic 
surfactants, EPA predicts toxicity to aquatic organisms may occur at 
concentrations that exceed 28 ppb for P-10-486 and 4 ppb for P-10-487 
in surface waters.
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test (OPPTS Test Guideline 850.1075); an aquatic 
invertebrate acute toxicity test, freshwater daphnids (OPPTS Test 
Guideline 850.1010); and an algal toxicity test, tiers I and II (OPPTS 
Test Guideline 850.5400) on P-10-487 would help characterize the 
environmental effects of the PMN substances. The PMN submitter agreed 
not to exceed the production volume limit in the consent order before 
conducting these tests.
    CFR citations: 40 CFR 721.10283 (P-10-486) and 40 CFR 721.10284 (P-
10-487).

PMN Number P-11-33

    Chemical name: Formaldehyde, polymer with 4-(1,1-
dimethylethyl)phenol, reaction products with 1-piperazineethanamine.
    CAS number: 1191244-16-2.
    Basis for action: The PMN states that the PMN substance will be 
used as a hardener for epoxy resin laminating systems. Based on 
ecological structure activity relationship (EcoSAR) analysis of test 
data on analogous aliphatic amines and phenol-amines, EPA predicts 
toxicity to aquatic organisms may occur at concentrations that exceed 
17 ppb of the PMN substance in surface waters. As described in the PMN, 
the substance is not released to surface waters. Therefore, EPA has not 
determined that the proposed manufacture, processing, or use of the 
substance may present an unreasonable risk. EPA has determined, 
however, that any use of the substance resulting in surface water 
concentrations exceeding 17 ppb may cause significant adverse 
environmental effects. Based on this information, the PMN substances 
meet the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test, freshwater (OPPTS Test Guideline 850.1075); an 
aquatic invertebrate acute toxicity test, freshwater daphnids (OPPTS 
Test Guideline 850.1010); and an algal toxicity test, tiers I and II 
(OPPTS Test Guideline 850.5400) would help characterize the 
environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10285.

PMN Number P-11-34

    Chemical name: Formaldehyde, polymer with .alpha.-(2-
aminomethylethyl)-.omega.-(2-aminomethylethoxy)poly[oxy(methyl-1,2-
ethanediyl)] and 4-(1,1-dimethylethyl)phenol.
    CAS number: 1192146-78-3.
    Basis for action: The PMN states that the PMN substance will be 
used as a hardener for epoxy resin laminating systems. Based on EcoSAR 
analysis of test data on analogous aliphatic amines and phenol-amines, 
EPA predicts toxicity to aquatic organisms may occur at concentrations 
that exceed 21 ppb of the PMN substance in surface waters. As described 
in the PMNs, the substances are not released to surface waters. 
Therefore, EPA has not determined that the proposed manufacture, 
processing, or use of the substance may present an unreasonable risk. 
EPA has determined, however, that any use of the substance resulting in 
surface water concentrations exceeding 21 ppb may cause significant 
adverse environmental effects. Based on this information, the PMN 
substances meet the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test, freshwater (OPPTS Test Guideline 850.1075); an 
aquatic invertebrate acute toxicity test, freshwater daphnids (OPPTS 
Test Guideline 850.1010); and an algal toxicity test, tiers I and II 
(OPPTS Test Guideline 850.5400) would help characterize the 
environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10286.

PMN Number P-11-188

    Chemical name: Infused carbon nanostructures (generic).
    CAS number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance is as an additive to provide 
conductive properties to reinforcements used in composites. Based on 
available information on analogous chemical substances, the PMN 
substance may cause lung effects. For the use described in the PMN, no 
significant inhalation exposures are expected. Therefore, EPA has not 
determined that the proposed manufacturing, processing, or use of the 
substance may present an unreasonable

[[Page 20300]]

risk. EPA has determined, however, that a manufacturing process other 
than as described in the PMN (the manufacturing process described in 
the PMN includes incorporation of the PMN substance into pellets) may 
cause serious health effects. Based on this information, the PMN 
substance meets the concern criteria at Sec.  721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of the 
following information would help characterize the health effects of the 
PMN substance: The dimensions, characteristics, and physical-chemical 
properties of the carbon nanostructures. These properties should be 
determined once a year for three consecutive years.
    CFR citation: 40 CFR 721.10287.

PMN Number P-11-316

    Chemical name: Cyclohexane, oxidized, by-products from, distn. 
residues.
    CAS number: 1014979-92-0.
    Basis for action: The PMN states that the generic (non-
confidential) uses of the substance are as an industrial solvent in 
closed and open systems, and as an accelerant in permitted industrial 
explosives. Based on EcoSAR analysis of test data on analogous esters, 
EPA predicts toxicity to aquatic organisms may occur at concentrations 
that exceed 4 ppb of the PMN substance in surface waters. As described 
in the PMN, the substance is not released to surface waters. Therefore, 
EPA has not determined that the proposed manufacturing, processing, or 
use of the substance may present an unreasonable risk. EPA has 
determined, however, that any use of the substance resulting in surface 
water concentrations exceeding 4 ppb may cause significant adverse 
environmental effects. Based on this information, the PMN substance 
meets the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test, freshwater and marine (OPPTS Test Guideline 
850.1075); an aquatic invertebrate acute toxicity test, fresh water 
daphnids (OPPTS Test Guideline 850.1010); and an algal toxicity test, 
tiers I and II (OPPTS Test Guideline 850.5400) would help characterize 
the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10288.

PMN Number P-11-333

    Chemical name: Hexanedioic acid polymer with aliphatic polyol 
dihydrogen phosphate aromatic ester (generic).
    CAS number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use will be as a component of industrial coatings. Based 
on EcoSAR analysis of test data on analogous organic phosphates, EPA 
predicts toxicity to aquatic organisms may occur if releases of the PMN 
substance to surface water from uses other than described in the PMN 
exceed the releases expected from the use described in the PMN. For the 
described use in the PMN, significant environmental releases are not 
expected. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substance may present an 
unreasonable risk. EPA has determined, however, that any use of the 
substance other than as described in the PMN may cause significant 
adverse environmental effects. Based on this information, the PMN 
substance meets the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a ready 
biodegradability test (OPPTS Test Guideline 835.3110); a fish early-
life stage toxicity test (OPPTS Test Guideline 850.1400); a daphnid 
chronic toxicity test (OPPTS Test Guideline 850.1300); and an algal 
toxicity test, tiers I and II (OPPTS Test Guideline 850.5400) would 
help characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10289.

PMN Number P-11-424

    Chemical name: Alkenoyloxy arylphenone (generic).
    CAS number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance is as a monomer for polymer 
applications. Based on test data on the PMN substance, and EcoSAR 
analysis of test data on analogous methacrylates, EPA predicts toxicity 
to aquatic organisms may occur at concentrations that exceed 26 ppb of 
the PMN substance in surface waters. As described in the PMN, releases 
to surface waters are not expected to exceed 26 ppb. Therefore, EPA has 
not determined that the proposed manufacture, processing, or use of the 
substance may present an unreasonable risk. EPA has determined, 
however, that any use of the substance resulting in surface water 
concentrations exceeding 26 ppb may cause significant adverse 
environmental effects. Based on this information, the PMN substance 
meets the concern criteria at Sec.  721.170(b)(4)(i) and (b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
early-life stage toxicity test (OPPTS Test Guideline 850.1400) and a 
daphnid chronic toxicity test (OPPTS Test Guideline 850.1300) would 
help characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10290.

PMN Number P-11-511

    Chemical name: C15 olefins (generic).
    CAS number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a petroleum substitute 
base. Based on EcoSAR analysis of test data on analogous neutral 
organics, EPA predicts toxicity to aquatic organisms may occur at 
concentrations that exceed 1 ppb of the PMN substance in surface 
waters. As described in the PMN, the substance is not released to 
surface waters. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substance may present an 
unreasonable risk. EPA has determined, however, that any use of the 
substance resulting in surface water concentrations exceeding 1 ppb may 
cause significant adverse environmental effects. Based on this 
information, the PMN substance meets the concern criteria at Sec.  
721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
early-life stage toxicity test (OPPTS Test Guideline 850.1400); a 
daphnid chronic toxicity test (OPPTS Test Guideline 850.1300); and an 
algal toxicity test, tiers I and II (OPPTS Test Guideline 850.5400) 
would help characterize the environmental effects of the PMN substance.
    CFR citation: 40 CFR 721.10291.

PMN Number P-11-546

    Chemical name: Silicate (2-), hexafluoro-, cesium (1:2).
    CAS number: 16923-87-8.
    Basis for action: The PMN states that the PMN substance will be 
used as a brazing (metal joining) agent. Based on submitted test data 
for an analogous PMN substance, EPA identified concerns for 
degeneration of the kidneys, necrosis of the heart muscle, and effects 
on the male reproductive organs to workers from inhalation exposure to 
the PMN substance. For the uses described in the PMN, significant 
dermal or inhalation exposure is not expected. Therefore, EPA has not 
determined that the proposed manufacturing, processing, or use of the 
substance may present an unreasonable risk. EPA has determined, 
however, use of the substance other than as a brazing (metal joining) 
agent may cause serious health effects. Based on this information, the 
PMN substance meets

[[Page 20301]]

the concern criteria at Sec.  721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of a 
repeated dose 28-day oral toxicity test (OPPTS Test Guideline 870.3050) 
in rodents would help characterize the human health effects of the PMN 
substance.
    CFR citation: 40 CFR 721.10292.

PMN Number P-11-578

    Chemical name: Benzoic acid, 4-(1,1-dimethylethyl)-, hydrazide.
    CAS number: 43100-38-5.
    Basis for action: The PMN states that the use of this substance 
will be as an intermediate. Based on SAR analysis of test data on 
analogous hydrazines, EPA identified concerns for mutagenicity, 
oncogenicity, developmental toxicity, dermal sensitization, and 
respiratory sensitization from exposure to the PMN substance via the 
inhalation route. In addition, based on EcoSAR analysis of analogous 
hydrazines, EPA predicts toxicity to aquatic organisms may occur at 
concentrations that exceed 2 ppb of the PMN substance in surface 
waters. For the intermediate use described in the PMN, inhalation 
exposures and environmental releases to surface waters are not 
expected. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substance may present an 
unreasonable risk. EPA has determined, however, that any use of the 
substance other than as an intermediate, or any use resulting in 
surface water concentrations exceeding 2 ppb may cause serious health 
effects and significant adverse environmental effects. Based on this 
information, the PMN substance meets the concern criteria at Sec.  
721.170(b)(1)(i)(C), (b)(3)(ii), and (b)(4)(ii).
    Recommended testing: EPA has determined that the results of a 90-
day oral toxicity test in rodents (OPPTS Test Guideline 870.3100) by 
the inhalation route; a carcinogenicity test (OPPTS Test Guideline 
870.4200) by the inhalation route, in two species of rodents; a fish 
acute toxicity test (OPPTS Test Guideline 850.1075); an aquatic 
invertebrate acute toxicity test, freshwater daphnids (OPPTS Test 
Guideline 850.1010); and an algal toxicity test, tiers I and II (OPPTS 
Test Guideline 850.5400) would help characterize the human health and 
environmental effects of the PMN substance.

    Chemical name: Cyclohexanol, 2,6-bis(1,1-dimethylethyl)-4-methyl-.
    CAS number: 163119-16-2.
    Basis for action: The PMN states that the use of this substance 
will be as an intermediate. Based on EcoSAR analysis of test data on 
analogous neutral organics, EPA predicts toxicity to aquatic organisms 
may occur at concentrations that exceed 2 ppb of the PMN substance in 
surface waters. As described in the PMN, releases to surface waters are 
not expected. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substance may present an 
unreasonable risk. EPA has determined, however, that any use resulting 
in surface water concentrations exceeding 2 ppb may cause significant 
adverse environmental effects. Based on this information, the PMN 
substance meets the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test (OPPTS Test Guideline 850.1075); an aquatic 
invertebrate acute toxicity test, freshwater daphnids (OPPTS Test 
Guideline 850.1010); and an algal toxicity test, tiers I and II (OPPTS 
Test Guideline 850.5400) would help characterize the environmental 
effects of the PMN substance.

PMN Number P-11-591

    Chemical name: IPDI modified isophthalic acid, neopentyl glycol and 
adipic acid (generic).
    CAS numbers: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a lamination adhesive. 
Based on test data on analogous substances, EPA identified concerns for 
oncogenicity, if the PMN substance is inhaled, as well as concerns for 
irritation to the eyes, skin, mucous membranes, and dermal and 
respiratory sensitization to workers from dermal and inhalation 
exposure to the PMN. For the industrial uses described in the PMN, and 
due to the use of personal protective equipment, significant worker 
exposure is unlikely, as dermal or inhalation exposure is not expected. 
Therefore, EPA has not determined that the proposed manufacturing, 
processing, or use of this substance may present an unreasonable risk. 
EPA has determined, however, that substantial production volume 
increases, or use of the substance in consumer products may cause 
serious health effects. Based on this information, the PMN substance 
meets the concern criteria at Sec.  721.170(b)(1)(i)(C) and (b)(3)(ii).
    Recommended testing: EPA has determined that the results of a 
dermal sensitization test (OPPTS Test Guideline 870.2600) and a 90-day 
inhalation toxicity test (OPPTS Test Guideline 870.3465) would help 
characterize the human health effects of the PMN substance.

    CAS number: 1313999-39-1.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an epoxy catalyst. Based 
on EcoSAR analysis of test data on polycationic polymers, EPA predicts 
toxicity to aquatic organisms may occur at concentrations that exceed 1 
ppb of the PMN substance in surface waters. As described in the PMN, 
the substance is not released to surface waters. Therefore, EPA has not 
determined that the proposed manufacturing, processing, or use of the 
substance may present an unreasonable risk. EPA has determined, 
however, that any use of the substance resulting in surface water 
concentrations exceeding 1 ppb may cause significant adverse 
environmental effects. Based on this information, the PMN substance 
meets the concern criteria at Sec.  721.170(b)(4)(ii).
    Recommended testing: EPA has determined that the results of a fish 
acute toxicity test (OPPTS Test Guideline 850.1075); an aquatic 
invertebrate acute toxicity test, freshwater daphnids (OPPTS Test 
Guideline 850.1010); and an algal toxicity test, tiers I and II (OPPTS 
Test Guideline 850.5400) would help characterize the environmental 
effects of the PMN substance. Additionally, EPA recommends that OPPTS 
Test Guideline 850.1000, ``Special Considerations for Conducting 
Aquatic Laboratory Studies'' be consulted for materials, such as this 
PMN substance, that are water insoluble or of low water solubility.

    Basis for action: The PMN states that the use of the substance will 
be as a polyurethane foam catalyst. Based on test data on the PMN 
substance, EPA identified concerns for dermal sensitization and blood 
and liver toxicity to workers from exposure to the PMN substance. For 
the industrial use described in the PMN, and due to the use of personal 
protective equipment,

[[Page 20302]]

significant worker exposure is unlikely, as dermal or inhalation 
exposure is not expected. Therefore, EPA has not determined that the 
proposed manufacturing, processing, or use of this substance may 
present an unreasonable risk. EPA has determined, however, that 
domestic manufacture of the substance or use of the substance in 
consumer products may cause serious health effects. Based on this 
information, the PMN substance meets the concern criteria at Sec.  
721.170(b)(3)(i).
    Recommended testing: EPA has determined that the results of a 28-
day dermal toxicity study (OPPTS Test Guideline 870.3200) would help 
characterize the human health effects of the PMN substance.

PMN Number P-11-662

    Chemical name: MDI terminated polyester polyurethane polymer 
(generic).
    CAS number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a liquid moisture cure 
adhesive. Based on test data on analogous diisocyanates, EPA identified 
concerns for mutagenicity, irritation to lungs and mucous membranes, 
and dermal and respiratory sensitization to workers from dermal and 
inhalation exposure to the PMN substance. For the industrial uses 
described in the PMN, and due to the use of personal protective 
equipment, significant worker exposure is unlikely, as dermal or 
inhalation exposure is not expected. Therefore, EPA has not determined 
that the proposed manufacturing, processing, or use of the substance 
may present an unreasonable risk. EPA has determined, however, that use 
of the substance in consumer products may cause serious health effects. 
Based on this information, the PMN substances meet the concern criteria 
at Sec.  721.170(b)(3)(ii).
    Recommended testing: EPA has determined that the results of a 
dermal sensitization test (OPPTS Test Guideline 870.2600) and a 90-day 
inhalation toxicity test (OPPTS Test Guideline 870.3465) would help 
characterize the human health effects of the PMN substance.
    CFR citation: 40 CFR 721.10298.

V. Rationale and Objectives of the Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are subject to these SNURs, EPA concluded that for two of the 17 
chemical substances, regulation was warranted under TSCA section 5(e), 
pending the development of information sufficient to make reasoned 
evaluations of the health or environmental effects of the chemical 
substances. The basis for such findings is outlined in Unit IV. Based 
on these findings, TSCA section 5(e) consent orders requiring the use 
of appropriate exposure controls were negotiated with the PMN 
submitters. The SNUR provisions for these chemical substances are 
consistent with the provisions of the TSCA section 5(e) consent orders. 
These SNURs are promulgated pursuant to Sec.  [emsp14]721.160 (see Unit 
II.).
    In the other 15 cases, where the uses are not regulated under a 
TSCA section 5(e) consent order, EPA determined that one or more of the 
criteria of concern established at Sec.  [emsp14]721.170 were met, as 
discussed in Unit IV.

B. Objectives

    EPA is issuing these SNURs for specific chemical substances which 
have undergone premanufacture review because the Agency wants to 
achieve the following objectives with regard to the significant new 
uses designated in this rule:
     EPA will receive notice of any person's intent to 
manufacture, import, or process a listed chemical substance for the 
described significant new use before that activity begins.
     EPA will have an opportunity to review and evaluate data 
submitted in a SNUN before the notice submitter begins manufacturing, 
importing, or processing a listed chemical substance for the described 
significant new use.
     EPA will be able to regulate prospective manufacturers, 
importers, or processors of a listed chemical substance before the 
described significant new use of that chemical substance occurs, 
provided that regulation is warranted pursuant to TSCA sections 5(e), 
5(f), 6, or 7.
     EPA will ensure that all manufacturers, importers, and 
processors of the same chemical substance that is subject to a TSCA 
section 5(e) consent order are subject to similar requirements.
    Issuance of a SNUR for a chemical substance does not signify that 
the chemical substance is listed on the TSCA Inventory. Guidance on how 
to determine if a chemical substance is on the TSCA Inventory is 
available on the Internet at http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

VI. Direct Final Procedures

    EPA is issuing these SNURs as a direct final rule, as described in 
Sec.  [emsp14]721.160(c)(3) and Sec.  [emsp14]721.170(d)(4). In 
accordance with Sec.  [emsp14]721.160(c)(3)(ii) and Sec.  
[emsp14]721.170(d)(4)(i)(B), the effective date of this rule is June 4, 
2012 without further notice, unless EPA receives written adverse or 
critical comments, or notice of intent to submit adverse or critical 
comments before May 4, 2012.
    If EPA receives written adverse or critical comments, or notice of 
intent to submit adverse or critical comments, on one or more of these 
SNURs before May 4, 2012, EPA will withdraw the relevant sections of 
this direct final rule before its effective date. EPA will then issue a 
proposed SNUR for the chemical substance(s) on which adverse or 
critical comments were received, providing a 30-day period for public 
comment.
    This rule establishes SNURs for a number of chemical substances. 
Any person who submits adverse or critical comments, or notice of 
intent to submit adverse or critical comments, must identify the 
chemical substance and the new use to which it applies. EPA will not 
withdraw a SNUR for a chemical substance not identified in the comment.

VII. Applicability of Rule to Uses Occurring Before Effective Date of 
the Rule

    Significant new use designations for a chemical substance are 
legally established as of the date of publication of this direct final 
rule, April 4, 2012.
    To establish a significant ``new'' use, EPA must determine that the 
use is not ongoing. The chemical substances subject to this rule have 
undergone premanufacture review. TSCA section 5(e) consent orders have 
been issued for two chemical substances and the PMN submitters are 
prohibited by the TSCA section 5(e) consent orders from undertaking 
activities which EPA is designating as significant new uses. 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 other 
person may commence such activities without first submitting a PMN. For 
chemical substances for which an NOC has not been submitted at this 
time, EPA concludes that the uses are not ongoing. However, EPA 
recognizes that prior to the effective date of the rule, when chemical 
substances identified in this SNUR are added to the TSCA Inventory, 
other persons may engage in a significant new use as defined in this 
rule before the effective date of the rule. However, 7 of the 17 
chemical substances contained in this rule have CBI chemical 
identities, and since EPA has received a limited number of post-

[[Page 20303]]

PMN bona fide submissions (per Sec. Sec.  720.25 and 721.11), the 
Agency believes that it is highly unlikely that any of the significant 
new uses described in the regulatory text of this rule are ongoing.
    As discussed in the April 24, 1990 SNUR, EPA has decided that the 
intent of TSCA section 5(a)(1)(B) is best served by designating a use 
as a significant new use as of the date of publication of this direct 
final rule rather than as of the effective date of the rule. If uses 
begun after publication were considered ongoing rather than new, it 
would be difficult for EPA to establish SNUR notice requirements 
because a person could defeat the SNUR by initiating the significant 
new use before the rule became effective, and then argue that the use 
was ongoing before the effective date of the rule. Thus, persons who 
begin commercial manufacture, import, or processing of the chemical 
substances regulated through this SNUR will have to cease any such 
activity before the effective date of this rule. To resume their 
activities, these persons would have to comply with all applicable SNUR 
notice requirements and wait until the notice review period, including 
all extensions, expires.
    EPA has promulgated provisions to allow persons to comply with this 
SNUR before the effective date. If a person meets the conditions of 
advance compliance under Sec.  721.45(h), the person is considered 
exempt from the requirements of the SNUR.

VIII. Test Data and Other Information

    EPA recognizes that TSCA section 5 does not require developing any 
particular test data before submission of a SNUN. The two exceptions 
are:
    1. Development of test data is required where the chemical 
substance subject to the SNUR is also subject to a test rule under TSCA 
section 4 (see TSCA section 5(b)(1)).
    2. Development of test data may be necessary where the chemical 
substance has been listed under TSCA section 5(b)(4) (see TSCA section 
5(b)(2)).
    In the absence of a TSCA section 4 test rule or a TSCA section 
5(b)(4) listing covering the chemical substance, persons are required 
only to submit test data in their possession or control and to describe 
any other data known to or reasonably ascertainable by them (see Sec.  
720.50). However, upon review of PMNs and SNUNs, the Agency has the 
authority to require appropriate testing. In cases where EPA issued a 
TSCA section 5(e) consent order that requires or recommends certain 
testing, Unit IV. lists those tests. Unit IV. also lists recommended 
testing for non-5(e) SNURs. Descriptions of tests are provided for 
informational purposes. EPA strongly encourages persons, before 
performing any testing, to consult with the Agency pertaining to 
protocol selection. To access the harmonized test guidelines referenced 
in this document electronically, please go to http://www.epa.gov/ocspp 
and select ``Test Methods and Guidelines.''
    In the TSCA section 5(e) consent orders for two of the chemical 
substances regulated under this rule, EPA has established production 
volume limits in view of the lack of data on the potential health and 
environmental risks that may be posed by the significant new uses or 
increased exposure to the chemical substances. These limits cannot be 
exceeded unless the PMN submitter first submits the results of toxicity 
tests that would permit a reasoned evaluation of the potential risks 
posed by these chemical substances. Under recent TSCA section 5(e) 
consent orders, each PMN submitter is required to submit each study at 
least 14 weeks (earlier TSCA section 5(e) consent orders required 
submissions at least 12 weeks) before reaching the specified production 
limit. Listings of the tests specified in the TSCA section 5(e) consent 
orders are included in Unit IV. The SNURs contain the same production 
volume limits as the TSCA section 5(e) consent orders. Exceeding these 
production limits is defined as a significant new use. Persons who 
intend to exceed the production limit must notify the Agency by 
submitting a SNUN at least 90 days in advance of commencement of non-
exempt commercial manufacture, import, or processing.
    The recommended tests specified in Unit IV. may not be the only 
means of addressing the potential risks of the chemical substance. 
However, submitting a SNUN without any test data may increase the 
likelihood that EPA will take action under TSCA section 5(e), 
particularly if satisfactory test results have not been obtained from a 
prior PMN or SNUN submitter. EPA recommends that potential SNUN 
submitters contact EPA early enough so that they will be able to 
conduct the appropriate tests.
    SNUN submitters should be aware that EPA will be better able to 
evaluate SNUNs which provide detailed information on the following:
     Human exposure and environmental release that may result 
from the significant new use of the chemical substances.
     Potential benefits of the chemical substances.
     Information on risks posed by the chemical substances 
compared to risks posed by potential substitutes.

IX. Procedural Determinations

    By this rule, EPA is establishing certain significant new uses 
which have been claimed as CBI subject to Agency confidentiality 
regulations at 40 CFR part 2 and 40 CFR part 720, subpart E. Absent a 
final determination or other disposition of the confidentiality claim 
under 40 CFR part 2 procedures, EPA is required to keep this 
information confidential. EPA promulgated a procedure to deal with the 
situation where a specific significant new use is CBI, at 40 CFR 
721.1725(b)(1).
    Under these procedures a manufacturer, importer, or processor may 
request EPA to determine whether a proposed use would be a significant 
new use under the rule. The manufacturer, importer, or processor must 
show that it has a bona fide intent to manufacture, import, or process 
the chemical substance and must identify the specific use for which it 
intends to manufacture, import, or process the chemical substance. If 
EPA concludes that the person has shown a bona fide intent to 
manufacture, import, or process the chemical substance, EPA will tell 
the person whether the use identified in the bona fide submission would 
be a significant new use under the rule. Since most of the chemical 
identities of the chemical substances subject to these SNURs are also 
CBI, manufacturers, importers, and processors can combine the bona fide 
submission under the procedure in Sec.  721.1725(b)(1) with that under 
Sec.  721.11 into a single step.
    If EPA determines that the use identified in the bona fide 
submission would not be a significant new use, i.e., the use does not 
meet the criteria specified in the rule for a significant new use, that 
person can manufacture, import, or process the chemical substance so 
long as the significant new use trigger is not met. In the case of a 
production volume trigger, this means that the aggregate annual 
production volume does not exceed that identified in the bona fide 
submission to EPA. Because of confidentiality concerns, EPA does not 
typically disclose the actual production volume that constitutes the 
use trigger. Thus, if the person later intends to exceed that volume, a 
new bona fide submission would be necessary to determine whether that 
higher volume would be a significant new use.

[[Page 20304]]

X. SNUN Submissions

    According to Sec.  721.1(c), persons submitting a SNUN must comply 
with the same notice requirements and EPA regulatory procedures as 
persons submitting a PMN, including submission of test data on health 
and environmental effects as described in Sec.  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 
Sec. Sec.  721.25 and 720.40. E-PMN software is available 
electronically at http://www.epa.gov/opptintr/newchems.

XI. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers, importers, and processors of 
the chemical substances subject to this rule. EPA's complete economic 
analysis is available in the docket under docket ID number EPA-HQ-OPPT-
2011-0942.

XII. Statutory and Executive Order Reviews

A. Executive Order 12866

    This rule establishes SNURs for several new chemical substances 
that were the subject of PMNs, or TSCA section 5(e) consent orders. The 
Office of Management and Budget (OMB) has exempted these types of 
actions from review under Executive Order 12866, entitled Regulatory 
Planning and Review (58 FR 51735, October 4, 1993).

B. Paperwork Reduction Act

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

C. Regulatory Flexibility Act

    On February 18, 2012, EPA certified pursuant to section 605(b) of 
the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), that 
promulgation of a SNUR does not have a significant economic impact on a 
substantial number of small entities where the following are true: (1) 
A significant number of SNUNs would not be submitted by small entities 
in response to the SNUR, and (2) the SNUN submitted by any small entity 
would not cost significantly more than $8,300. A copy of that 
certification is available in the docket for this rule.
    This rule is within the scope of the February 18, 2012 
certification. Based on the Economic Analysis discussed in Unit XI and 
EPA's experience promulgating SNURs (discussed in the certification), 
EPA believes that the following are true: (1) A significant number of 
SNUNs would not be submitted by small entities in response to the SNUR 
and (2) submission of the SNUN would not cost any small entity 
significantly more than $8,300. Therefore, the promulgation of the SNUR 
would not have a significant economic impact on a substantial number of 
small entities.

D. Unfunded Mandates Reform Act

    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 rule. As 
such, EPA has determined that this rule does not impose any enforceable 
duty, contain any unfunded mandate, or otherwise have any affect on 
small governments subject to the requirements of sections 202, 203, 
204, or 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 
104-4).

E. Executive Order 13132

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

F. Executive Order 13175

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

G. Executive Order 13045

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

H. Executive Order 13211

    This action is not subject to Executive Order 13211, entitled 
Actions Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use (66 FR 28355, May 22, 2001), because this action 
is not expected to affect energy supply,

[[Page 20305]]

distribution, or use and because this action is not a significant 
regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act

    In addition, since this action does not involve any technical 
standards, section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 
U.S.C. 272 note), does not apply to this action.

J. Executive Order 12898

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

XIII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. This rule is not a 
``major rule'' as defined by 5 U.S.C. 804(2).
