Modification of Significant New Uses of Certain Chemical 
Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to amend the significant new use rules 
(SNURs) under section 5(a)(2) of the Toxic Substances Control Act 
(TSCA) for 24 chemical substances which were the subject of 
premanufacture notices (PMNs). This action would amend the SNURs to 
allow certain uses without requiring a significant new use notice 
(SNUN), and would extend SNUN requirements to certain additional uses. 
EPA is proposing these amendments based on review of new data as 
described for each chemical substance. This action would requires 
persons who intend to manufacture (including import) or process any of 
these 24 chemical substances for an activity that is designated as a 
significant new use by this proposed rule to notify EPA at least 90 
days before commencing that activity. The required notification would 
provide EPA with the opportunity to evaluate the intended use and, if 
necessary, to prohibit or limit that activity before it occurs.

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 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 a modified SNUR must 
certify their compliance with the SNUR requirements. The EPA policy in 
support of import certification appears at 40 CFR part 707, subpart B. 
In addition, any persons who export or intend to export the chemical 
substance that is the subject of a final rule 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 amendments to the SNURs for 24 chemical substances 
in 40 CFR part 721 subpart E. This proposed action would require 
persons who intend to manufacture or process these chemical substances 
for an activity that is designated as a significant new use by these 
amended rules to notify EPA at least 90 days before commencing that 
activity. 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.

[[Page 19038]]

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

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including the four bulleted TSCA section 5(a)(2) 
factors, listed in Unit III. of this document. Once EPA determines that 
a use of a chemical substance is a significant new use, TSCA section 
5(a)(1)(B) requires persons to submit a significant new use notice 
(SNUN) to EPA at least 90 days before they manufacture or process the 
chemical substance for that use. Persons who must report are described 
in Sec.  721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to the rule, recordkeeping 
requirements, exemptions to reporting requirements, and applicability 
of the rule to uses occurring before the effective date of the 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 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 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 24 
chemical substances that are the subject of these SNURs, EPA considered 
relevant information about the toxicity of the chemical substance, 
likely human exposures and environmental releases associated with 
possible uses, taking into consideration the four bulleted TSCA section 
5(a)(2) factors listed in this unit.

IV. Substances Subject to a Proposed Significant New Use Rule Amendment

    EPA is proposing to amend the significant new use and recordkeeping 
requirements for 24 chemical substances in 40 CFR part 721 Subpart E. 
In this unit, EPA provides the following information for each chemical 
substance:
     PMN number and SNUN 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).
     Federal Register publication date and reference for the 
final SNUR previously issued.
     Basis for the Proposed Amendment.
     Tests recommended by EPA to provide sufficient information 
to evaluate the chemical substance (see Unit VII. for more 
information).
     CFR citation assigned in the regulatory text section of 
this rule.

PMN Number P-99-669, SNUN Number S-09-1, and SNUN Number S-13-29

    Chemical name: Oxirane, methyl-, polymer with oxirane, mono 
(3,5,5,-trimethylhexyl) ether.
    CAS number: 204336-40-3.
    Federal Register publication date and reference: March 28, 2003 (68 
FR 15061) (FRL-6758-7).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance for the PMN and the SNUN is 
as a wetting agent. The original SNUR was issued based on meeting the 
concern criteria at Sec.  721.170 (b)(4)(ii). The original SNUR 
required notification if the chemical substance was used for uses other 
than as described in the PMN. On November 12, 2008 EPA received a SNUN, 
S-09-1, and on June 4, 2013 EPA received a SNUN, S-13-29 for the 
chemical substance describing uses different than those in the PMN. The 
90-day review period for the SNUNs expired with EPA not taking action 
on the significant new uses described in the SNUNs. Based on structural 
analogy to nonionic surfactants, EPA is still concerned that toxicity 
to aquatic organisms may occur at a concentration of 600 parts per 
billion (ppb) in surface waters. Because EPA finds that the substance 
is not released to surface waters in significant quantities as 
described in either the PMN or the SNUNs, EPA has not determined that 
the proposed manufacturing, processing, and use of the substance may 
present an unreasonable risk. EPA has determined, however, that other 
uses of the substance may cause significant adverse environmental 
effects. Based on this the substance meets the concern criteria at 
Sec.  721.170 (b)(4)(ii). Based on these findings, EPA is proposing to 
modify the SNUR to allow the uses described in S-09-01 and S-13-29.
    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 text, freshwater 
daphnids (OPPTS Test Guideline 850.1010); and an algal toxicity test 
(OCSPP Test Guideline 850.4500) would help characterize the 
environmental effects of the chemical substance.
    CFR citation: 40 CFR 721.522.

PMN Number P-00-618 and SNUN Numbers S-05-03 and S-11-4

    Chemical name: 1-Butanol, 3-methoxy-3-methyl-, acetate.
    CAS number: 103429-90-9.
    Federal Register publication date and reference: March 28, 2003 (68 
FR 15061) (FRL-6758-7).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance for the PMN is as a 
processing aid. The uses of the chemical substance for the SNUNs are as 
an organic solvent of polyurethane plastic coating, an ingredient in 
various kinds of paint thinner, an organic solvent of polyurethane 
resin, an ingredient of cleaning agents, an organic solvent for screen 
ink, an ingredient in airplane paint, and a solvent for inkjet printer 
ink. EPA identified concerns for liver toxicity, kidney toxicity, 
developmental neurotoxicity and carcinogenicity based on analog data. 
The original SNUR was issued based on meeting the concern criteria at 
Sec.  721.170 (b)(3)(i), (b)(3)(ii), and (b)(1)(i)(C). The original 
SNUR required notification if the chemical substance was used for use 
other than as described in the PMN. On March 23, 2005, EPA received a 
SNUN, S-05-3, for the chemical substance describing

[[Page 19039]]

uses different than those in the PMN. Based on the activities described 
in this SNUN, a TSCA section 5(e) consent order was issued for the SNUN 
submitter under sections 5(e)(1)(A)(i) and (e)(1)(A)(ii)(I) based on a 
finding that the substance may present an unreasonable risk of injury 
to human health. On October 26, 2010, EPA received a SNUN, S-11-4, for 
a new use, which was as a solvent for inkjet printer ink. The SNUN 
submitter also submitted a chromosome aberration study, a mouse 
lymphoma assay and a combined repeated dose study with reproductive and 
developmental toxicity. Based on the test data for the chemical 
substance which was submitted with S-11-4, EPA continues to have 
concerns for liver toxicity and kidney toxicity for exposed workers and 
consumers. In response to S-11-4, EPA allowed the new use and modified 
the consent order accordingly, while continuing to protect against any 
unreasonable risks of injury to human health. The modified consent 
order requires:
    1. Workers to use personal protective equipment to prevent dermal 
exposure.
    2. Establishment and use of a hazard communication program, 
including human health, environmental hazard precautionary statements 
on each label and the Material Safety Data Sheet (MSDS).
    3. Not manufacture the substance in the United States.
    4. Not use the substance in consumer products.
    5. Limit the percent concentration of the substance to 10% or less 
in final products whose use involves an application method that 
generates a vapor, mist, or aerosol, except for commercial/professional 
inkjet printing in a commercial (excluding retail) print shop.
    The proposed SNUR designates as a significant new use the absence 
of these protective measures when using the substance for any use other 
than as described in the PMN.
    Recommended testing: EPA has determined that the results of a two-
year chronic toxicity study (OPPTS Test Guideline 870.4100) via the 
dermal and inhalation routes would help characterize the health effects 
of the PMN substance.
    CFR citation: 40 CFR 721.532.

PMN Number P-98-1275 and SNUN Number S-11-10

    Chemical name: Aluminosilicates, phospho-.
    CAS number: 201167-69-3.
    Federal Register publication date and reference: December 26, 2000 
(65 FR 81386) (FRL-6592-8).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance for the PMN and the SNUN is 
as a catalyst. A consent order was issued for the PMN under section 
5(e)(1)(A)(i) and section 5(e)(1)(A)(ii)(I) of TSCA based on a finding 
that the substance may present an unreasonable risk of injury to human 
health. The original SNUR, based on the requirements in the TSCA 
section 5(e) consent order, required notification if the PMN substance 
was used without the respiratory protection described in the SNUR 
(i.e., a National Institute of Occupational Safety and Health (NIOSH) 
respirator with an Assigned Protection Factor (APF) of 2000), the 
hazard communication program described in the SNUR was not used, or the 
aggregate production volume in the consent order was exceeded. Upon 
receipt and evaluation of the 90-day inhalation study required in the 
consent order, EPA continues to find that the substance may present an 
unreasonable risk of lung effects and cancer, although at a higher 
dose/effect level. Based on this finding, EPA modified the consent 
order to remove the production volume limit and reduce the required 
protection level for the respirator to an APF of 50. On June 14, 2011, 
EPA received a SNUN, S-11-10, for the chemical substance to use a 
respirator with an APF of 50 and to exceed the production volume limit. 
EPA permitted the new uses for the same reasons it modified the consent 
order. The proposed SNUR designates as a ``significant new use'' the 
absence of the respiratory protection and hazard communication measures 
in the modified consent order.
    Recommended testing: EPA has determined that the results of a two-
year two-species oral carcinogenicity study (OPPTS Test Guideline 
870.4200) would help characterize the health effects of the PMN 
substance.
    CFR citation: 40 CFR 721.633.

PMN Number P-00-7 and SNUN Numbers S-05-1, S-06-4, S-07-3, and S-07-5

    Chemical name: D-Glucuronic acid, polymer with 6-deoxy-L-mannose 
and D-glucose, acetate, calcium magnesium potassium sodium salt.
    CAS number: 125005-87-0.
    Federal Register publication date and reference: December 17, 2003 
(68 FR 70155) (FRL-7307-3).
    Basis for the modified significant new use rule: The uses of the 
chemical substance as described in the PMN are as an oilfield drilling 
fluid, an oilfield spacer fluid, in oilfield cementing, in cementitious 
packaged products, in concrete applications, and in foam applications. 
Based on structural analogues and submitted test data, EPA identified 
concerns for lung effects from inhalation exposure to the chemical 
substance. The original SNUR was issued based on meeting the concern 
criteria at Sec.  721.170(b)(3)(i) and (b)(3)(ii). The original SNUR 
required notification if the chemical substance was used for any use 
other than those described in PMN. EPA received SNUN S-05-1 on December 
1, 2004, S-06-4 on February 28, 2006, S-07-3 on June 5, 2007, and S-07-
5 on July 17, 2007. Each SNUN described different uses for the chemical 
substance than those described in the PMN: S-05-1 described use as a 
sealant, S-06-4 described a generic use in pipeline transmission 
systems, S-07-3 described any uses other than those already allowed in 
the SNUR where less than 5 percent of the chemical substance consists 
of particles below 10 microns, and S-07-05 described a generic use in a 
commercial dry wash additive. As with the PMN, the Agency in its review 
of the SNUNs found that significant inhalation exposure remains 
unlikely when used as described in the SNUNs, and accordingly, EPA has 
not determined that the proposed manufacturing, processing, and use of 
the chemical substance may present an unreasonable risk. EPA has 
determined, however, that use of the chemical substance where more than 
5 percent of the chemical substance contains particles below 10 microns 
may cause significant health effects. Based on this information, the 
chemical substance meets the concern criteria at Sec.  721.170(b)(3)(i) 
and (b)(3)(ii). Based on these findings EPA is proposing to modify the 
SNUR to remove the notification requirement for specific end uses and 
instead require notification where more than 5 percent of the chemical 
substance consists of particles below 10 microns.
    Recommended testing: EPA has determined that the 90-day inhalation 
toxicity study with a 60-day holding period (OPPTS Test Guideline 
870.3465) would help to characterize the human health effects of the 
PMN substance. Attention should be given to the lungs, including 
histopathology of the lungs (inflammation, epithelial hyperplasia, and 
fibrosis), (HAL) analysis for markers of lung injury, and lung burden 
analysis for clearance of the test material (EPA-748-R-96-001). The 
neurotoxicity components and examination of organs other than the

[[Page 19040]]

lungs are not required in the 90-day study.
    CFR citation: 40 CFR 721.2076.

PMN Number P-95-169 and SNUN Numbers S-08-7 and S-14-1

    Chemical name: 2-Propen-1-one, 1-(4-morpholinyl)-.
    CAS number: 5117-12-4.
    Federal Register publication date and reference: Jan. 5, 2000 (65 
FR 354) (FRL-6055-2), amended May 13, 2011 (76 FR 27910) (FRL-8871-5).
    Basis for the modified significant new use rule: The use for P-95-
169 is as a diluent for ultraviolet and electron beam curable resins 
for coatings, inks, and curable adhesives, and the use for S-14-1 is as 
a monomer for use in ultraviolet ink jet applications. The generic 
(non-confidential) use for S-08-7 is a contained use in energy 
production. A consent order for the PMN was issued under sections 
5(e)(1)(A)(i) and 5(e)(l)(A)(ii)(I) of TSCA based on a finding that the 
chemical substance may present an unreasonable risk of injury to human 
health and the environment. To protect against these risks, the Agency 
issued a TSCA section 5(e) consent order which became effective on 
November 27, 1998. The order required the use of dermal personal 
protective equipment (including gloves demonstrated to be impervious) 
and respiratory personal protective equipment (including a NIOSH-
approved respirator); required establishment of a hazard communication 
program; prohibited domestic manufacturing; prohibited processing and 
use activities in non-enclosed processes; established maximum 
production volume limits for submission of required testing; 
established waste disposal practices (including restrictions for no 
release to surface waters and requirement of disposal only in a 
Resource Conservation Recovery Act ((RCRA) hazardous waste landfill); 
and prohibited use of the chemical substance involving an application 
method that generates a vapor, mist, or aerosol.
    A SNUR was issued for this chemical substance on January 5, 2000. 
The SNUR designated as a ``significant new use'' the absence of the 
protective measures required in the consent order.
    Subsequent to issuance of the SNUR, the PMN submitter completed the 
following studies under the terms of the TSCA section 5(e) consent 
order: An in vivo mouse micronucleus test, a 90-day oral toxicity study 
in rats, and a reproductive toxicity screening study in rats. The 
results of the micronucleus test were negative. Based on the results of 
the 90-day study, the Agency established a no observed adverse effect 
level (NOAEL) of 20 milligram/kilogram/day (mg/kg/day) for 
neurotoxicity. Further, based on the results of the reproductive 
toxicity screening study, a NOAEL of 75 mg/kg/day (highest dose tested) 
was established for reproductive effects. From these data, the Agency 
calculated Margins of Exposure (MOEs) for predicted workplace 
exposures.
    Based on these new data, concerns remained for possible effects to 
the liver, testes, kidney, and blood from dermal exposure. However, EPA 
no longer had substantial human health concerns for mutagenicity and 
neurotoxicity. In addition, Agency concerns for carcinogenicity by 
inhalation were reduced, but were further mitigated by retaining the 
original consent order prohibition of industrial processing and use in 
a non-enclosed process and any use application methods that generate a 
vapor, mist, or aerosol form of the PMN substance.
    In addition, to account for data received on analogous substances 
since the initial PMN was submitted and to address Agency environmental 
concerns, a re-review of the environmental toxicity profile for the 
chemical substance was conducted. The results of this evaluation 
indicated a low concern for chronic aquatic toxicity. Therefore, EPA 
could no longer make a ``may present unreasonable risk'' finding for 
releases of the PMN substance to surface waters. As a result of this 
review, EPA issued a modified TSCA section 5(e) consent order which 
became effective on May 9, 2006. The modified order removed 
requirements for respiratory protection, waived further required 
trigger testing, removed the restriction on domestic manufacture, and 
removed waste disposal restrictions. Pursuant to Sec.  721.185(a)(5), 
the Agency examined new information and reexamined the test data and 
other information supporting its finding under section 
5(e)(1)(A)(ii)(I) of TSCA, and concluded that a rational basis no 
longer existed to support findings that certain activities involving 
the substance may present an unreasonable risk of injury to human 
health and the environment required under section 5(e)(1)(A) of TSCA.
    To protect against the remaining potential risks, the modified 
consent order:
     Requires the use of dermal personal protective equipment 
(including gloves demonstrated to be impervious).
     Requires establishment of a hazard communication program.
     Prohibits processing and use activities in non-enclosed 
processes.
     Prohibits the use of the chemical substance involving an 
application method that generates a vapor, mist, or aerosol.
    On June 27, 2008, the Agency received a SNUN, S-08-7, for the 
subject chemical substance. The significant new use identified in the 
notice was release to water for the generic (non-confidential) use of 
``contained use in energy production''. The 90-day review period for 
the SNUN expired on October 2, 2008 with EPA not taking action on the 
``significant new use'' of release of the substance to water.
    On May 13, 2011, EPA issued a modified SNUR based on and consistent 
with the provisions in the underlying modified consent order which no 
longer included release to water as a significant new use. In addition, 
EPA included, in the regulatory text, clarifying language for those 
forms of the PMN substance which are exempt from the provisions of the 
proposed SNUR. The SNUR does not apply to quantities of the PMN 
substance after it has been completely reacted (cured) because the PMN 
substance will no longer exist.
    On October 21, 2013, EPA received a second SNUN, S-14-1, for the 
subject chemical substance. The significant new use identified in the 
notice was processing and use in a non-enclosed process as a monomer 
for use in ultraviolet ink jet applications. The 90-day review period 
for the SNUN expired on March 13, 2014, with EPA not taking action on 
the significant new use of processing and use in a non-enclosed process 
as a monomer for use in ultraviolet ink jet applications. When 
evaluating this new use, EPA also evaluated potential environmental 
releases. Based on a new review of test data on the chemical substance, 
EPA predicts toxicity to aquatic organisms may occur at concentrations 
that exceed 100 ppb of the chemical substance in surface waters. As 
described in the PMN and SNUNs, releases of the substance are not 
expected to result in surface water concentrations that exceed 100 ppb. 
EPA has determined, however, that any use of the substance resulting in 
surface waters concentrations exceeding 100 ppb may result in 
significant adverse environmental effects. Based on this information, 
the chemical substance meets the concern criteria at Sec.  721.170 
(b)(4)(i). The proposed SNUR designates as a ``significant new use''

ppb, or use other than as a monomer for use in ultraviolet ink jet 
applications unless the chemical substance is processed and used in an 
enclosed process.
    Recommended testing: EPA has determined that the results of the 
combined repeated dose toxicity with the reproductive/developmental 
toxicity screening test (OPPTS Test Guideline 870.3650) would help 
further characterize the human health effects of the PMN substance. The 
modified TSCA section 5(e) consent order does not require submission of 
the aforementioned information at any specified time or production 
volume. However, the order's restrictions on manufacturing, processing, 
distribution in commerce, use and disposal of the chemical substance 
will remain in effect until the order is modified or revoked by EPA 
based on submission of that or other relevant information.

PMN Numbers P-88-2179 and P-89-0539 and SNUN Number S-08-3

    Chemical name: Oxirane, 2,2'-(1,6-hexanediylbis(oxymethylene))bis-.
    CAS number: 16096-31-4.
    Federal Register publication date and reference: April 25, 1991 (56 
FR 19228).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance in the PMNs and the SNUN is 
in coatings and as a diluent. A consent order was issued under sections 
5(e)(1)(A)(i) and 5(e)(l)(A)(ii)(I) of TSCA based on a finding that the 
chemical substance may present an unreasonable risk of injury to human 
health and the environment. To protect against these risks, the Agency 
issued a TSCA section 5(e) consent order which became effective on 
October 12, 1990. The order required the use of dermal personal 
protective equipment including impervious gloves and respiratory 
personal protective equipment including a NIOSH-approved respirator; 
required establishment of a hazard communication program; prohibited 
non-industrial use; established maximum production volume limits for 
submission of required testing; established requirements for release to 
surface waters during manufacturing and allowed no release to surface 
waters during processing and use. On February 4, 2008, EPA received a 
SNUN, S-08-3, for the chemical substance. The significant new use 
identified in the notice was a non-industrial use. The 90-day review 
period for the SNUN expired on October 2, 2008, with EPA not taking 
action on the ``significant new use'' of the industrial use described 
in the SNUN. The proposed SNUR designates as a ``significant new use'' 
any non-industrial use other than as described in the SNUN and retains 
the other significant new uses which are the absence of the other 
protective measures required in the consent order.
    Recommended testing: EPA has determined that the results of a 90-
day oral subchronic study with special attention given to the pathology 
of the reproductive organs (OPPTS Test Guideline 870.3100), a two-year 
two-species oral carcinogenicity study (OPPTS Test Guideline 870.4200), 
a fish acute toxicity test (OPPTS Test Guideline 850.1075), an aquatic 
invertebrate acute toxicity text (OPPTS Test Guideline 850.1010) and an 
algal toxicity test (OCSPP Test Guideline 850.4500) would help further 
characterize the human health and environmental effects of the PMN 
substance. The consent order requires the PMN submitter to conduct the 
90-day oral toxicity test (OPPTS Test Guideline 870.3100) before 
exceeding the confidential production limit in the consent order.

PMN Number P-95-638 and SNUN Numbers P-97-79 and S-06-8

    Chemical name: Pentane 1,1,1,2,3,4,4,5,5,5,-decafluoro.
    CAS number: 138495-42-8.
    Federal Register publication date and reference: January 22, 1998 
(63 FR 3394) (FRL-5720-3).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance for the PMN is as a carrier 
fluid and for the two SNUNs the generic (non-confidential) use is as 
test media. The original SNUR was issued based on meeting the concern 
criteria at Sec.  721.170 (b)(4)(i). The original SNUR required 
notification if the chemical substance was used for uses other than 
described in the PMN or the first SNUN P-97-79 (at that time SNUNs were 
designated with a ``P'' number; later submissions received an ``S'' 
designation). On February 4, 2008, EPA received a second SNUN, S-06-8, 
for the subject chemical substance. The significant new use identified 
in S-06-8 was the specific confidential use described in the notice. 
The 90-day review period for the SNUN expired on July 17, 2006, with 
EPA not taking action on the significant new use described in the SNUN. 
The proposed SNUR designates as a significant new use, any use other 
than the uses described in the PMN and the SNUNs.
    Recommended testing: None.
    CFR citation: 40 CFR 721.5645.

PMN Number P-00-1220 and SNUN Number S-07-2

    Chemical name: Phenol-biphenyl polymer condensate (generic).
    CAS number: Claimed confidential.
    Federal Register publication date and reference: August 20, 1998 
(63 FR 44562) (FRL-5788-7).
    Basis for the modified significant new use rule: The use of the 
chemical substance for the PMN is in electric molding and for the SNUN 
is as a component in photoresist manufacture. The original SNUR was 
issued based on meeting the concern criteria at Sec.  
721.170(b)(4)(ii). The original SNUR required notification if the PMN 
substance was released to water. On January 8, 2007, EPA received SNUN, 
S-07-2, for the chemical substance describing releases to water. The 
90-day review period for the SNUN expired with the Agency not taking 
action on the significant new uses described in the SNUN because the 
water releases did not exceed 1 ppb, the Agency's surface water 
concentration of concern for adverse effects of the substance to 
aquatic organisms. The PMN submitter subsequently submitted a fish 
early-life stage ecotoxicity study for the chemical substance. Based on 
this submitted study and structural analogy to phenols, EPA is still 
concerned that toxicity to aquatic organisms may occur at a 
concentration of 5 ppb in surface waters. Because EPA finds that the 
chemical substance is not released to surface waters above 5 ppb as 
described in the PMN and SNUN, EPA has not determined that the proposed 
manufacturing, processing, and use of the substance may present an 
unreasonable risk. EPA has determined, however, that other uses of the 
substance may cause significant adverse environmental effects. Based on 
this the substance meets the concern criteria at Sec.  721(b)(4)(i) and 
(b)(4)(ii). Based on these findings, EPA is proposing to modify the 
SNUR to require notification if water releases exceed 5 ppb in surface 
waters.
    Recommended testing: EPA has determined that an aquatic 
invertebrate acute toxicity text (OPPTS Test Guideline 850.1010) and an 
algal toxicity test (OCSPP Test Guideline 850.4500) would help further 
characterize the environmental effects of the chemical substance.

PMN Number P-01-320 and SNUN Numbers S-04-2 and S-11-1

    Chemical name: Propane,1,1,1,2,2,3,3-heptafluoro-3-methoxy-.

[[Page 19042]]

    CAS number: 375-03-1.
    Federal Register publication date and reference: December 17, 2003 
(68 FR 70155) (FRL-7307-3).
    Basis for the modified significant new use rule: The use of the 
chemical substance for the PMN is as a heat transfer fluid and a 
refrigerant. The use for S-04-2 is for aerosol spray cleaning. The use 
for S-11-1 is for flush cleaning, foam blowing, deposition coatings, 
histology baths, and vapor degreasing. The original SNUR was issued 
based on meeting the concern criteria at Sec.  721.170 (b)(3)(i) and 
(b)(3)(ii). The original SNUR required notification if the chemical 
substance was used other than as a heat transfer fluid or refrigerant, 
or if the annual production volume exceeded 100,000 kilograms. On March 
29, 2004, EPA received SNUN, S-04-2, for the chemical substance 
describing a new use of aerosol spray cleaning for industrial and 
commercial use. The 90-day review period for the SNUN expired on June 
26, 2004 with EPA not taking action on the significant new use of 
aerosol spray cleaning for industrial and commercial use. On January 4, 
2011, EPA received a SNUN, S-11-1, for the chemical substance 
describing new uses of flush cleaning, foam blowing, deposition 
coatings, histology baths, and vapor degreasing and exceeding an annual 
production volume of 100,000 kilograms. The 90-day review period for S-
11-1 expired on September 23, 2011 with EPA not taking action on the 
significant new uses described in the SNUN. EPA continues to identify 
health concerns for liver and kidney toxicity based on submitted test 
data on the chemical substance and cardiac sensitization and 
developmental toxicity based on analog data. For the uses described in 
the PMN and SNUNs, significant occupational exposure is not expected. 
Therefore, EPA has not determined that the proposed manufacturing, 
processing, or use will present an unreasonable risk. EPA has 
determined, however, that any uses of the substance other than those 
described in the PMN and SNUNs may result in serious health effects. 
Based on this information, the PMN substance meets the concern criteria 
at Sec.  721.170 (b)(3)(i) and (b)(3)(ii). The proposed SNUR 
modification designates as a ``significant new use'' any use other than 
the uses described in the PMN and SNUNs. The proposed SNUR modification 
no longer designates the significant new use of exceeding an annual 
production volume of 100,000 kilograms.
    Recommended testing: EPA has determined that the results of a 90-
day oral subchronic study (OPPTS Test Guideline 870.3100) would help to 
characterize the human health effects of the PMN substance.

PMN Number P-01-781

    Chemical name: Silane, triethoxy[3-oxiranylmethoxy)propyl]-.
    CAS number: 2602-34-8.
    Federal Register publication date and reference: Dec. 17, 2003 (68 
FR 70155) (FRL-7307-3).
    Basis for the modified significant new use rule: The original SNUR 
was issued resulting in listing the incorrect CAS number as 2602-34-2 
for the chemical substance in the Code of Federal Regulations. The 
proposed SNUR modification is designating the correct CAS number of 
2602-34-8. The original findings and requirements of the SNUR are the 
same.
    CFR citation: 40 CFR 721.9501.

PMN Number P-00-1132 and SNUN Number S-11-5

    Chemical name: Siloxanes and silicones, aminoalkyl, fluorooctyl, 
hydroxy-terminated salt (generic).
    CAS number: Claimed confidential.
    Federal Register publication date and reference: March 28, 2003 (68 
FR 15061) (FRL-6758-7).
    Basis for the modified significant new use rule: The use of the 
chemical substance for the PMN is in anti-graffiti systems and for the 
SNUN is as a surface treatment and additive for coatings, adhesives, 
sealants, paste, insulation and textiles for porous, non-porous, 
ceramic, metal, glass, plastic, wood and leather surfaces; and a 
surface treatment agent for inorganic filler particles. The original 
SNUR was issued based on meeting the concern criteria at Sec.  721.170 
(b)(3)(ii). The original SNUR required notification if the chemical 
substance was used for use other than described in PMN or for an 
application that generates a vapor, mist, or aerosol. On January 5, 
2011, EPA received a SNUN, S-11-5, for the chemical substance 
describing uses different than those in the PMN. EPA also reviewed a 
90-day inhalation study that was submitted for the substance in the 
SNUN. The results of the study demonstrated a Lowest Observed Adverse 
Effect Level (LOAEL) of 30 milligram/cubic meter (mg/m\3\) for lung 
effects. The 90-day review period for the SNUN expired with the Agency 
not taking action on the significant new uses described in the SNUN. 
Since EPA continues to find that significant worker exposure is 
unlikely when used as described in the PMN and SNUN, EPA has not 
determined that the proposed manufacturing, processing, and use of the 
substance may present an unreasonable risk. EPA has determined, 
however, that other uses of the substance or applications that generate 
a vapor, mist, or aerosol could result in exposures which may cause 
serious health effects. Based on this information the substance meets 
the concern criteria at Sec.  721(b)(3)(ii). Based on these findings, 
EPA is proposing to modify the SNUR to require notification for any 
uses other than described in the PMN and the SNUN.
    Recommended Testing: EPA has determined that the results of a 
decomposition kinetics by thermo gravimeter (ASTM Test Guideline 
E1641), a compositional analysis by thermo gravimeter (ASTM Test 
Guideline E1131), and a laboratory burn test by a protocol to be agreed 
upon by EPA and the company conducting the study, would help to further 
characterize the environmental fate of the PMN substance.

    Chemical name: Benzenesulfonic acid, mono C-10-16 -alkyl 
derivs., compds. with 2-propen-1-amine (PMN P-97-296 and SNUN S-03-10) 
and Alkyl benzene sulfonic acids and alkyl sulfates, amine salts (PMN 
P-97-297/298/299 and SNUN S-03-11/12/13).
    CAS number: 195008-77-6 (PMN P-97-296 and SNUN S-03-10) and
    Claimed confidential (PMN P-97-297/298/299 and SNUN S-03-11/12/13).
    Federal Register publication date and reference: August 20, 1998 
(63 FR 44562) (FRL-5788-7).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substances for the PMNs and the SNUNs 
is as a processing aid. The original SNUR was issued based on meeting 
the concern criteria at Sec.  721.170 (b)(4)(i) and (b)(4)(ii). The 
original SNUR required notification if the PMN substances were released 
to water. On March 4, 2003, EPA received SNUNs S-03-10, S-03-11, S-03-
12, and S-03-13 for the chemical substances describing releases to 
water. The 90-day review period for the SNUNs expired with EPA not 
taking action on the significant new uses described in the SNUNs 
because the water releases did not exceed 30 ppb. Based on submitted 
data and structural analogy to anionic surfactants, EPA is still 
concerned that toxicity to aquatic organisms may occur at a 
concentration of 30 ppb in surface waters. Because EPA finds that the 
substances are not

[[Page 19043]]

released to surface waters above 30 ppb as described in the PMN and 
SNUN, EPA has not determined that the proposed manufacturing, 
processing, and use of the substances may present an unreasonable risk. 
EPA has determined, however, that other uses of the substances may 
cause significant adverse environmental effects. Based on this the 
substances meet the concern criteria at Sec.  721.170 (b)(4)(i) and 
(b)(4)(ii). Based on these findings EPA is proposing to modify the SNUR 
to require notification if water releases exceed 30 ppb in surface 
waters.
    Recommended testing: EPA has determined that a fish acute toxicity 
test (OPPTS Test Guideline 850.1075), an aquatic invertebrate acute 
toxicity text (OPPTS Test Guideline 850.1010) and an algal toxicity 
test (OCSPP Test Guideline 850.4500) would help further characterize 
the human health and environmental effects of the PMN substance.

PMN Number P-90-226 and SNUN Numbers P-96-1408, S-08-6, S-09-4, and S-
13-49

    Chemical name: Titanate [Ti6O13 (2-)], 
dipotassium.
    CAS number: 12056-51-8.
    Federal Register publication date and reference: August 13, 1991 
(56 FR 40204).
    Basis for the modified significant new use rule: The generic use of 
the chemical substance is as a friction material. A consent order was 
issued under sections 5(e)(1)(A)(i) and 5(e)(l)(A)(ii)(I) of TSCA based 
on a finding that the chemical substance may present an unreasonable 
risk of injury to human health. To protect against these risks, EPA 
issued a TSCA section 5(e) consent order which became effective on 
February 21, 1991. The order required the establishment of a hazard 
communication program; prohibited domestic manufacturing; prohibited 
non-industrial use; established maximum production volume limits for 
submission of required testing; prohibited manufacture other than by 
the manufacturing method in P-90-226; and required the bulk density 
measurements of the PMN substance in the pure form to be less than 0.4 
gram/cubic centimeter (g/cm\3\). A SNUR was issued for this chemical 
substance on August 13, 1991. The SNUR designated as a ``significant 
new use'' the absence of the protective measures required in the 
consent order. On July 15, 1996, EPA received a SNUN, P-96-1408 (at 
that time SNUNs were designated with a ``P'' number; later submissions 
received an ``S'' designation); on June 23, 2008, EPA received S-08-6; 
on March 30, 2009, EPA received S-09-4; and on July 17, 2013, EPA 
received S-13-49 for the chemical substance. The significant new use 
for each SNUN was a manufacturing method other than described in P-90-
226. EPA took no action during the 90-day review periods for the SNUNs 
and allowed the significant new uses because EPA determined that none 
of the manufacturing processes produced respirable acicular fibers with 
an average aspect ratio of less than 5, and as a result were not 
considered by EPA to pose an unreasonable risk of lung toxicity to 
workers. In addition, a 90-day inhalation study was submitted by the 
PMN submitter under the terms of the TSCA section 5(e) consent order 
and an intratracheal instillation study submitted by the submitter of 
S-09-4 demonstrated no evidence of fibrosis in test animals. The 
proposed SNUR modification designates as a significant new use any 
domestic manufacture, non-industrial use, any manufacturing process 
other than described in the PMN and the SNUNs, and any manufacture that 
produces respirable, acicular fibers with an average aspect ratio 
greater than 5. The proposed SNUR modification no longer designates 
establishment of a hazard communication program or exceeding an 
aggregate production volume limit as a significant new use.
    Recommended testing: EPA has determined that the results of a 90-
day inhalation toxicity test (OPPTS Test Guideline 870.3465) and a 
carcinogenicity test (OPPTS Test Guideline 870.4200) via the inhalation 
route would help characterize the potential human health effects of the 
chemical substance from alternate methods of manufacture.

PMN Number P-93-1649 and SNUN Numbers S-04-3 and S-11-3

    Chemical name: 1,3-Dimethyl-2-imidazolidinone.
    CAS number: 80-73-9.
    Federal Register publication date and reference: August 30, 1995 
(60 FR 45072) (FRL-4926-2).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance for the PMN is as a process 
raw material and for the SNUNs is as a printing ink ingredient. The 
consent order was issued under sections 5(e)(1)(A)(i) and 
5(e)(l)(A)(ii)(I) of TSCA based on a finding that the chemical 
substance may present an unreasonable risk of injury to human health. 
To protect against these risks, EPA issued a TSCA section 5(e) consent 
order which became effective on August 25, 1994. The order required the 
use of dermal personal protective equipment (including gloves 
demonstrated to be impervious) and required establishment of a hazard 
communication program; prohibited domestic manufacture; prohibited non-
industrial uses; and established maximum production volume limits for 
submission of required testing. The SNUR issued for this chemical 
substance on August 30, 1995, designated as a significant new use the 
absence of the protective measures required in the consent order. On 
August 16, 2004, EPA received S-04-3 and on October 21, 2010, EPA 
received S-11-3 for the chemical substance. The significant new use for 
both SNUNs was a non-industrial use. The 90-day review period for both 
SNUNs expired with the Agency not taking action on the significant new 
uses described in the SNUNs. The PMN submitter conducted a dermal 
developmental toxicity study and a 90-day dermal subchronic study on 
the PMN substance. The results of the developmental study was a 
maternal chronic toxicity NOAEL of 10 mg/kg/day and a development 
toxicity NOAEL of 100 mg/kg/day. The results of the 90-day dermal study 
was a NOAEL of 500 mg/kg/day. Because EPA continues to find that dermal 
exposures may cause an unreasonable risk of human health effects, EPA 
is proposing to modify the SNUR to allow the commercial use (specific 
use claimed confidential) as described in the SNUNs but is retaining 
all other significant new uses and requirements in the SNUR.
    Recommended testing: None.
    CFR citation: 40 CFR 721.9892.

PMN Number P-00-1121

    Chemical name: Manganese strontium oxide (MnSrO3).
    CAS number: 12163-45-0.
    Federal Register publication date and reference: March 29, 2007 (72 
FR 14681) (FRL-7699-5).
    Basis for the modified significant new use rule: The generic (non-
confidential) use of the chemical substance is as a pigment. A consent 
order was issued under sections 5(e)(1)(A)(i) and 5(e)(l)(A)(ii)(I) of 
TSCA based on a finding that the chemical substance may present an 
unreasonable risk of injury to human health and the environment. To 
protect against these risks, the order required establishment of a 
hazard communication program; established maximum aggregate volume 
limits for submission of required testing; limited release to surface 
waters; and prohibited manufacture, process, or use of the PMN 
substance if the particle size is less than

[[Page 19044]]

10 microns. EPA received a 96-hour toxicity test with rainbow trout for 
the chemical substance. No mortality was observed at concentrations up 
to the highest concentration tested of 16,000 milligram/Liter (mg/L). 
Based on these test results, EPA modified the consent order to remove 
the aggregate volume limit and the surface water release limits. The 
modified consent order retains the hazard communication requirements 
and the particle size limitations to continue to prevent any 
unreasonable risk of injury to human health. The proposed SNUR 
modification designates as a significant new use the absence of the 
protective measures in the modified consent order.
    Recommended testing: EPA has determined that a 90-day inhalation 
toxicity study with a 60-day holding period (OPPTS Test Guideline 
870.3465) and a two-year inhalation carcinogenicity study (OPPTS Test 
Guideline 870.4200) would help to characterize the human health effects 
of the PMN substance.
    CFR citation: 40 CFR 721.10008.

PMN Number P-07-601 and SNUN Number S-14-11

    Chemical name: 1-Propene, 2,3,3,3-tetrafluoro-.
    CAS number: 754-12-1.
    Federal Register publication date and reference: October 27, 2010 
(75 FR 65987) (FRL-8846-8) and November 1, 2013 (78 FR 65570) (FRL-
9901-97).
    Basis for modification of the SNUR: The use of the chemical 
substance for the PMN was as a refrigerant in motor vehicle air 
conditioning systems in new passenger cars and vehicles and the use for 
the SNUN was as a refrigerant for stationary refrigeration and 
stationary air conditioning. The original SNUR was issued based on 
meeting the concern criteria at Sec.  721.170. The original SNUR 
required notification if the chemical substance was used for uses other 
than as described in the PMN. On May 12, 2014 EPA received a SNUN, S-
14-11, for the chemical substance describing uses different than those 
in the PMN. The 90-day review period for the SNUN expired with EPA not 
taking action on the significant new uses described in the SNUN. Based 
on toxicity test data conducted on the PMN substance, EPA is still 
concerned that toxicity to humans may occur at inhalation exposures of 
1,900 ppm. Because EPA finds that exposures from uses described in 
either the PMN or the SNUN do not result in human exposures that cause 
an unreasonable risk to human health, EPA has not determined that the 
proposed manufacturing, processing, and use of the substance, including 
certain commercial, and consumer uses of the substance, may cause 
significant adverse health effects. Based on this the substance meets 
the concern criteria at Sec.  721.170. Based on these findings, EPA is 
proposing to modify the SNUR to allow the uses described in S-14-11.
    CFR citation: 40 CFR 721.10182.

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

    Chemical name: Poly[oxy(methyl-1,2- ethanediyl)], .alpha.-
sulfo-.omega.-hydroxy-, C12-13-branched and linear alkyl ethers, sodium 
salts (P-10-486) and Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-
sulfo-.omega.-hydroxy-, C14-15-branched and linear alkyl ethers, sodium 
salts (P-10-487).
    CAS number: 958238-81-8 (P-10-486) and 958238-82-9 (P-10-487).
    Federal Register publication date and reference: April 4, 2012 (77 
FR 20296) (FRL-9333-3).
    Basis for the modified significant new use rule: The PMNs state 
that the use of these substances will be for downhole injection for 
enhanced oil recovery. Based on structure activity relationship 
analysis of test data on analogous anionic surfactants, EPA predicts 
toxicity to aquatic organisms may occur at concentrations that exceed 
28 ppb for P10-486 and 4 ppb for P10-487 in surface waters. 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 these 
risks, the Agency issued a TSCA section 5(e) consent order which became 
effective on July 22, 2011. 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 ppb for P-10-486 and 4 ppb for P-10-487. A 
SNUR was issued for this chemical substance on April 4, 2012. The SNUR 
designated as a ``significant new use'' the absence of any of these 
measures required in the consent order.
    EPA had evaluated the results of a combined biodegradation and 
aquatic toxicity test for P-10-486 during PMN review. The test was 
submitted as part of the PMN submissions. During the review, EPA 
accepted the data as valid for purposes of ascertaining the 
environmental fate of the PMN substances (the overall rate of ready 
biodegradation), but not for purposes of determining potential 
environmental toxicity of the transformation products to aquatic 
organisms. Subsequent to issuance of the SNUR, and based on discussions 
with the Company and other PMN submitters, EPA re-evaluated the data 
and determined that the data could be used to evaluate the aquatic 
toxicity of the PMN transformation products. The combined 
biodegradation/ecological toxicity testing demonstrated that, 
subsequent to the biodegradation portion of the combined study, no 
further ecologically toxic substances remained from the P-10-486 parent 
substance. EPA also believes the results of the test data for P-10-486 
apply to the structurally analogous P-10-487 substance. Based on this 
evaluation EPA did not find that the PMN substances present an 
unreasonable risk to the environment or human health or will be 
produced in substantial quantities and may reasonably be anticipated to 
enter the environment in substantial quantities based on activities 
described in the PMN. As a result EPA revoked the consent order. EPA 
has determined, however, that other uses of the substances may cause 
significant adverse environmental effects. Based on this information, 
the chemical substances meets the concern criteria at Sec.  
721.170(b)(4)(i) and (b)(4)(ii). Based on these findings EPA is 
proposing to modify the SNUR to require notification of any use of the 
substances without disposal by incineration or injection into a Class I 
or II waste disposal well; release to water without prior biological 
treatment (activated sludge or equivalent) plus clarification; or non-
industrial use.
    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.

PMN Numbers P-10-58, P-10-59, P-10-60, and P-10-184

    Chemical names: Partially fluorinated alcohol substituted glycols 
(generic).
    CAS numbers: Not available.
    Federal Register publication date and reference: September 11, 2013 
(78 FR 55632) (FRL-9398-7).
    Basis for the modified significant new use rule: The PMNs state 
that the

[[Page 19045]]

generic (non-confidential) uses of P-10-58 and P-10-59 will be as 
intermediates in the manufacture of P-10-60, and the generic use of P-
10-60 and P-10-184 will be as a surface active agent or surfactant. EPA 
has concerns for potential incineration or other decomposition products 
of the PMN substances. These perfluorinated decomposition products may 
be released to the environment from incomplete incineration of the PMN 
substances at low temperatures. EPA has preliminary evidence, including 
data on some fluorinated polymers, which suggests that, under some 
conditions, the PMN substances could degrade in the environment. EPA 
has concerns that these degradation products will persist in the 
environment, could bioaccumulate or biomagnify, and could be toxic to 
people, mammals, and birds. These concerns are based on data on 
analogous chemical substances, including perfluorooctanoic acid (PFOA) 
and other perfluorinated alkyls, including the presumed environmental 
degradant. The orders were issued under TSCA sections 5(e)(1)(A)(i), 
5(e)(1)(A)(ii)(I), and 5(e)(1)(A)(ii)(II), based on a finding that 
these substances may present an unreasonable risk of injury to the 
environment and human health, the substances may be produced in 
substantial quantities and may reasonably be anticipated to enter the 
environment in substantial quantities, and there may be significant (or 
substantial) human exposure to the substances and their potential 
degradation products. To protect against these risks, the consent order 
for P-10-58/59/60 requires manufacture (which includes import) of the 
PMN substances according to the chemical synthesis and composition 
section of the TSCA section 5(e) consent order, including analysis, 
reporting, and limitations of maximum impurity levels of certain 
fluorinated impurities, restricts the use of P-10-58 and P-10-59 as 
intermediates to make P-10-60, and submission of testing on the PMN 
substance P-10-60 at five identified aggregate manufacture volumes. A 
SNUR was issued for these chemical substances on September 11, 2013 
designating as significant new uses the absence of these measures. To 
protect against potential risks, the consent order for P-10-184 
requires manufacture of the PMN substance according to the chemical 
synthesis and composition section of the TSCA section 5(e) consent 
order, including analysis, reporting, and limitations of maximum 
impurity levels of certain fluorinated impurities and manufacture of P-
10-184 only when the mean number of moles of the ethoxy group is 
between 3 and 11 or the average number molecular weight is between 496 
and 848 daltons based on the amounts of raw materials charged to the 
reactor. EPA is modifying the SNUR to add P-10-184 because it is the 
same chemical substance as P-10-60 and to make the SNUR requirements 
consistent with both consent orders by proposing to add a significant 
new use that requires reporting if P-10-60/P-10-184 are manufactured 
other than when the mean number of moles of the ethoxy group is between 
3 and 11 or the average number molecular weight is between 496 and 848 
daltons.
    Recommended testing: EPA has determined that the results of certain 
fate and physical/chemical property testing identified in the TSCA 
section 5(e) consent orders would help characterize possible effects of 
the PMN substances and their degradation products. The TSCA section 
5(e) consent order for P-10-58/59/60 contains five production volume 
limits. The PMN submitter has agreed not to exceed the confidential 
production volume limits without performing the specified testing on 
PMN substance P-10-60. Additional testing is included in the preambles 
to the TSCA section 5(e) consent orders but this testing is not 
required at any specified time or production volume. However, the TSCA 
section 5(e) consent order restrictions on manufacture, processing, 
distribution in commerce, use, and disposal of the PMN substances will 
remain in effect until the TSCA section 5(e) consent orders are 
modified or revoked by EPA based on submission of that or other 
relevant information.
    CFR citation: 40 CFR 721.10515.

V. Rationale for the Proposed Rule

    Pursuant to Sec.  721.185 and as described in Unit IV, this 
proposed rule includes 23 chemical substances where EPA determined, 
based on new information, there is no need to require additional notice 
from persons who propose to engage in identical or similar activities, 
or a rational basis no longer exists for the findings that activities 
involving the substance may present an unreasonable risk of injury to 
human health or the environment required under section 5(e)(1)(A) of 
the Act.
    This proposed rule also includes a chemical substance, P-01-781, 
where EPA is modifying the chemical identity information.

VI. Applicability of the Proposed Rule to Uses Occurring Before 
Effective Date of the Final Rule

    To establish a significant ``new'' use, EPA must determine that the 
use is not ongoing. EPA solicits comments on whether any of the uses 
proposed as significant new uses are ongoing. As discussed in the 
Federal Register issue of April 24, 1990 (55 FR 17376), 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 the proposed SNUR rather than as of the effective date 
of the final 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 proposed significant new use before the rule became 
effective, and then argue that the use was ongoing as of the effective 
date of the final rule.
    Thus, any persons who begin commercial manufacture or processing 
activities with the chemical substances that are not currently a 
significant new use under the current rule but which would be regulated 
as a ``significant new use'' if this proposed rule is finalized, must 
cease any such activity as of the effective date of the rule if and 
when finalized. 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 were to meet the conditions 
of advance compliance under Sec.  721.45(h), the person would be 
considered to have met the requirements of the final SNUR for those 
activities.

VII. Test Data and Other Information

    EPA recognizes that TSCA section 5 does not require the development 
of 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

[[Page 19046]]

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 this case, EPA 
recommends persons, before performing any testing, to consult with the 
Agency pertaining to protocol selection. To access the OCSPP test 
guidelines referenced in this document electronically, please go to 
http://www.epa.gov/ocspp and select ``Test Methods and Guidelines.'' 
The Organisation for Economic Co-operation and Development (OECD) test 
guidelines are available from the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at http://www.sourceoecd.org. ASTM 
International standards are available at http://www.astm.org/Standard/index.shtml.
    The recommended testing specified in Unit IV. of the proposed rule 
may not be the only means of addressing the potential risks of the 
chemical substance. However, SNUNs submitted 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.

VIII. SNUN Submissions

    According to 40 CFR 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 40 CFR 720.50. SNUNs must be 
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 
721.25 and 40 CFR 720.40. E-PMN software is available electronically at 
http://www.epa.gov/opptintr/newchems.

IX. Economic Analysis

    EPA evaluated the potential costs of SNUN requirements for 
potential manufacturers and processors of the chemical substances in 
the proposed rule. The Agency's complete Economic Analysis is available 
in the docket under docket ID number EPA-HQ-OPPT-2014-0649.

 X. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed action would modify SNURs for 24 chemical substances 
that were the subject of PMNs. The Office of Management and Budget 
(OMB) has exempted these types of actions from review under Executive 
Order 12866, entitled Regulatory Planning and Review (58 FR 51735, 
October 4, 1993).

B. Paperwork Reduction Act (PRA)

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

C. Regulatory Flexibility Act (RFA)

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

D. Unfunded Mandates Reform Act (UMRA)

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

[[Page 19047]]

or 205 of the UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et 
seq.).

E. Executive Order 13132

    This action 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 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 proposed rule.

G. Executive Order 13045

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

H. Executive Order 13211

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

I. National Technology Transfer and Advancement Act (NTTAA)

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

J. Executive Order 12898

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