Proposed Significant New Use Rule on Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing significant new use rules (SNURs) under the 
Toxic Substances Control Act (TSCA) for 13 chemical substances which 
were the subject of premanufacture notices (PMNs). This action would 
require persons who intend to manufacture (including import) or process 
any of the 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 the activity before it occurs.

DATES: Comments must be received on or before March 9, 2015.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
process, or use the chemical substances contained in this proposed 
rule. The following list of North American Industrial Classification 
System (NAICS) codes is not intended to be exhaustive, but rather 
provides a guide to help readers determine whether this document 
applies to them. Potentially affected entities may include:
    <bullet> Manufacturers (including importers) 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; 
see also 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 chemical substances subject to a 
final 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 a chemical substance that is the subject of this final rule are 
subject to the export notification provisions of TSCA section 12(b) (15 
U.S.C. 2611(b)) (see 40 CFR 721.20), and must comply with the export 
notification requirements in 40 CFR part 707, subpart D.

B. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
regulations.gov or email. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as 
CBI and then identify electronically within the disk or CD-ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When preparing and submitting 
your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.

II. Background

A. What action is the agency taking?

    EPA is proposing these SNURs under TSCA section 5(a)(2) for 13 
chemical substances which were the subject of PMNs P-13-270, P-13-365, 
P-13-392, P-13-393, P-13-471, P-13-563, P-13-617, P-13-618, P-13-619, 
P-14-60, P-14-267, P-14-268, and P-14-478. These SNURs would require 
persons who intend to manufacture or process any of these chemical 
substances for an activity that is designated as a significant new use 
to notify EPA at least 90 days before commencing that activity. In the 
Federal Register publications of February 12, 2014 (79 FR 8273) (FRL-
9903-70), July 8, 2014 (79 FR 38464) (FRL-9911-05), and July 9, 2014 
(79 FR 39268) (FRL-9910-01), EPA issued direct final SNURs on ten of 
these 13 chemical substances, which are the subject of PMNs P-13-365, 
P-13-392, P-13-393, P-13-471, P-13-270, P-13-563, P-13-617, P-13-618, 
P-13-619, and P-14-60 in accordance with the procedures at Sec.  
721.160(c)(3)(i). EPA received notices of intent to submit adverse 
comments on these SNURs. Therefore, as required by Sec.  
721.160(c)(3)(ii), EPA removed the direct final SNURs in separate final 
rules published in the Federal Register of April 14, 2014 (71 FR 20800) 
(FRL-9909-25) and September 4, 2014 (79 FR 52563) (FRL-9915-69), and is 
now issuing this proposed rule on these ten chemical substances. The 
records for the direct final SNURs on these ten chemical substances 
were established as dockets EPA-HQ-OPPT-2013-0739, EPA-HQ-OPPT-2014-
0166, and EPA-HQ-OPPT-2014-0277. Those records include information 
considered by the Agency in developing the direct final rule. Adverse 
comments received regarding these substances and the direct final rule 
are discussed in Unit IV. This proposed rule also includes three SNURs 
for the three chemicals which are the subject of PMNs, P-14-267, P-14-
268, and P-14-478 and for which there has not been any previous 
rulemaking. The record for the SNURs on these three chemicals was 
established as docket EPA-HQ-OPPT-2014-0760. That record includes 
information considered by the Agency in developing these three proposed 
SNURs.

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

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including the four bulleted TSCA section 5(a)(2) 
factors listed in Unit III. Once EPA determines that a use of a 
chemical substance is a significant new use, TSCA section 5(a)(1)(B) 
requires persons to submit a significant new use notice (SNUN) to EPA 
at least 90 days before they manufacture or process the chemical 
substance for that use. 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 final 
rule. Provisions relating to user fees appear at 40 CFR part 700. 
According to 40 CFR 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 sections 5(b) and 5(d)(1), the exemptions authorized by

[[Page 847]]

TSCA sections 5(h)(1), (h)(2), (h)(3), and (h)(5), and the regulations 
at 40 CFR part 720. Once EPA receives a SNUN, EPA 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:
    <bullet> The projected volume of manufacturing and processing of a 
chemical substance.
    <bullet> The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
    <bullet> The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
    <bullet> 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 
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, taking into consideration the four bulleted TSCA section 
5(a)(2) factors listed in this unit.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements 
for 13 chemical substances in 40 CFR part 721, subpart E. In this unit, 
EPA provides the following information for each chemical substance:
    <bullet> PMN number.
    <bullet> Chemical name.
    <bullet> Chemical Abstracts Service (CAS) Registry number (assigned 
for non-confidential chemical identities).
    <bullet> Public comments and EPA's response to comments on the ten 
direct final SNURs subject to PMNs, P-13-365, P-13-392, P-13-393, P-13-
471, P-13-270, P-13-563, P-13-617, P-13-618, P-13-619, and P-14-60.
    <bullet> Tests recommended by EPA to provide sufficient information 
to evaluate the chemical substance (see Unit VII. for more 
information).
    <bullet> CFR citation assigned in the regulatory text section of 
this proposed rule.
    The regulatory text section of this proposed rule specifies the 
activities designated as significant new uses. Certain new uses, 
including production volume limits (i.e., limits on manufacture volume) 
and other uses designated in this proposed rule, may be claimed as CBI.

PMN Number P-13-270

    Chemical name: Aromatic dibenzoate (generic).
    CAS number: Claimed confidential.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance is as a catalyst component. Based on 
structural activity relationship (SAR) analysis of test data on 
analogous esters, EPA predicts chronic toxicity to aquatic organisms 
may occur at concentrations that exceed 1 ppb of the PMN substance in 
surface waters. Based on uses described in the PMN, releases of the 
substance are not expected to result in surface water concentrations 
that exceed 1 ppb. 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 should there be 
any new use of the substance resulting in releases to surface waters 
exceeding 1 ppb significant adverse environmental effects could occur. 
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 
sediment-water chironomid life-cycle toxicity test using spiked water 
or spiked sediment (OECD Test Guideline 233); a hydrolysis test (OECD 
Test Guideline 111); and a Zahn-Wellens inherent biodegradation test 
(OECD Test Guideline 302B) would help characterize the potential for 
environmental effects of the PMN substance. EPA also recommends that 
the guidance document on aquatic toxicity testing of difficult 
substances and mixtures (OECD Test Guideline 23) be followed to 
facilitate solubility in the test media, because of the PMN substance's 
low water solubility.
    CFR citation: 40 CFR 721.10735.

PMN Number P-13-365

    Chemical name: MDI modified polyalkene glycols (generic).
    CAS number: Not available.
    1. Public comment: One commenter claimed SNUR requirements 
associated with P-13-365 for respiratory protection, record-keeping, 
and hazard communication are difficult to understand and implement and 
they add another layer of complexity for potential customers. Customers 
are likely to choose existing adhesive system chemicals with no or 
fewer SNUR requirements which may have greater risk potential to avoid 
having to comply with the SNUR requirements of P-13-365 and similar new 
chemicals.
    1. EPA response: The proposed SNUR does not contain significant new 
use reporting requirements pertaining to hazard communication. EPA has 
issued numerous SNURs with similar recordkeeping and worker protection 
requirements that other manufacturers and processors have complied with 
and implemented. The comment period for the proposed rule is an 
opportunity to provide more detail on specific issues or challenges 
posed by the proposed SNUR reporting requirements, as well as potential 
suggestions for EPA to better clarify those requirements. Unless EPA 
receives specific, quantitative information that demonstrates the 
chemical substances subject to these proposed SNURs exhibit a lower 
potential for the hazards and risks described in the proposed SNUR or 
that they will specifically replace a chemical substance with a higher 
potential for hazards and risks, EPA would expect to issue the SNUR as 
proposed to provide the Agency with the opportunity to review any new 
uses for potential unreasonable risks. As described in the Agency's 
ongoing Action Plan for MDI and TDI, diisocyanates are well-known 
dermal and inhalation sensitizers in the workplace and have been 
documented to cause asthma, lung damage, and in severe cases, fatal 
reactions. EPA is concerned about potential health effects that may 
result from exposures of consumers or self-employed workers while using 
products containing uncured (unreacted) MDI and TDI and its related 
polyisocyanates (e.g., spray-applied foam sealants, adhesives, and 
coatings) or incidental exposures to the general population while such 
products are used in or around buildings including homes or schools. 
While workers may already be using protective controls in occupational 
settings, due to the nature of the potential risk posed by these 
chemicals, EPA believes it is prudent to emphasize its concern

[[Page 848]]

through respiratory protection requirements where there is potential 
for inhalation exposure, in addition to proposing significant new uses 
such as consumer use and application method. Accordingly, the 
regulatory action for new diisocyanates reflects EPA's policy of 
consistent treatment of the entire class of potentially hazardous 
chemicals, regardless of their statutory status as ``new'' or 
``existing'' chemicals. EPA continues to work to lessen the apparent 
inequity between regulations of new and existing chemicals.
    2. Public comment: The same commenter questioned whether EPA's 
basis for adverse human health concerns stem from the residual 
diisocyanate monomer or the P-13-365 substance. The P-13-365 substance 
is not expected to be volatile under any use.
    2. EPA response: The basis for EPA's health concern is for the P-
13-365 substance which includes the presence of any residual 
diisocyanate monomer. In addition, EPA finds that there are unreacted 
isocyanate groups in the polymer and that there is a significant 
percentage of the polymer with molecular weight below 1,000. EPA agrees 
that the higher molecular weight components of the P-13-365 substance 
are not expected to be volatile. The residual diisocyanate monomer is 
expected to be volatile and lower molecular components could be 
volatile resulting in a higher potential for exposure.
    3. Public comment: The same commenter proposes that instead of 
recommending the 90-day inhalation toxicity test (OPPTS Test Guideline 
870.3465) to characterize the human health effects of the P-13-365 
substance, EPA should consider a Differential Scanning Calorimetric or 
Thermogravimetric Analysis of the PMN substance to assess vaporization 
potential. The 90-day inhalation toxicity test would require delivery 
of the PMN substance as a mist or aerosol which the associated SNUR 
prohibits. In addition, the results of the test may be heavily 
influenced by the residual diisocyanate and not exhibit effects from 
the PMN substance itself.
    3. EPA response: In the ``Recommended testing'' section, the 90-day 
inhalation toxicity and the dermal sensitization tests, are listed as 
an appropriate way to characterize potential health effects. EPA will 
consider any other testing, data, or information that would be relevant 
to assessing potential health effects. The proposed SNUR would require 
notification if a method was used that generates a mist or aerosol. 
Conducting the 90-day inhalation toxicity test could address the 
potential lung effects and respiratory sensitization if a significant 
new use notice was submitted to EPA. As stated in the response to 
comment 2, EPA is concerned about the health effects of any residual 
monomer as well as unreacted isocyanate groups on the polymer.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an adhesive component. 
Based on test data on analogous diisocyanates, EPA identified concerns 
for dermal and respiratory sensitization, and lung and mucous membrane 
irritation effects. For the use described in the PMN, EPA does not 
expect significant occupational or any consumer inhalation exposure due 
to the use of adequate personal protective equipment and because the 
substance is not applied using a method that generates a vapor, mist, 
or aerosol nor is it used in a consumer product. 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 without a NIOSH-certified 
particulate respirator (with eye/face protection, when dermal and/or 
ocular exposure is likely) with an APF of at least 10, where there is a 
potential for inhalation exposure; any use of the substance in consumer 
products; or any use of the substance involving an application method 
that generates a vapor, mist, or aerosol, 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 a skin 
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.

PMN Number P-13-392

    Chemical name: Acrylic acid esters polymers, reaction products with 
polyisocyanate (generic).
    CAS number: Not available.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be for wood, plastic, and 
automotive paint material. Based on test data on analogous 
diisocyanates, EPA identified concerns for dermal and respiratory 
sensitization, lung and mucous membrane irritation, and lung effects if 
inhaled based on the low molecular weight isocyanates. As described in 
the PMN, worker inhalation exposure is not expected and dermal exposure 
will be minimal due to the use of adequate personal protective 
equipment and consumer exposure is not expected because the substance 
will not be used in consumer products. 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 without a NIOSH-certified 
particulate respirator (with eye/face protection, when dermal and/or 
ocular exposure is likely) with an APF of at least 10, where there is a 
potential for inhalation exposure, or any use of the PMN substance in a 
consumer product, 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 a skin 
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 721.10719.

PMN Number P-13-393

    Chemical name: 1,3-Benzenedicarboxylic acid, polymer with 1,4-
benzenedicarboxylic acid, 1,4-dimethyl 1,4-benzenedicarboxylate, 2,2-
dimethyl-1,3-propanediol,dodecanedioic acid, 1,2-ethanediol, 
hexanedioic acid, 1,6-hexanediol, alkyldiol ester and aromatic 
isocyanate (generic).
    CAS number: Not available.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an industrial adhesive. 
Based on test data on analogous diisocyanates, the Agency identified 
concerns for dermal and respiratory sensitization, lung and mucous 
membrane irritation, and lung effects if inhaled based on the low 
molecular weight isocyanates. For the use described in the PMN, EPA 
does not expect significant occupational or any consumer inhalation 
exposure due to the use of adequate personal protective

[[Page 849]]

equipment and because the substance is not applied using a method that 
generates a vapor, mist, or aerosol nor is the substance used in a 
consumer product. 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 without a NIOSH-certified particulate respirator (with eye/
face protection, when dermal and/or ocular exposure is likely) with an 
APF of at least 10, where there is a potential for inhalation exposure; 
any use of the substance in consumer products; or any use of the 
substance involving an application method that generates a vapor, mist, 
or aerosol, 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 a skin 
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 721.10720.

PMN Number P-13-471

    Chemical name: Methylene diisocyanate polymer with polypropylene 
glycol and diols (generic).
    CAS number: Not available.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as an industrial adhesive. 
Based on test data on analogous diisocyanates, EPA identified concerns 
for oncogenicity, mutagenicity, respiratory and dermal sensitization, 
and lung and mucous membrane irritation. As described in the PMN, 
worker inhalation exposure is not expected and dermal exposure will be 
minimal due to the use of adequate personal protective equipment, and 
consumer exposure is not expected because the substance will not be 
used in consumer products. 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 without a NIOSH-certified particulate respirator (with eye/
face protection, when dermal and/or ocular exposure is likely) with an 
APF of at least 10, where there is a potential for inhalation exposure 
or the use of the substance in a consumer product, 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 skin 
sensitization test (OPPTS Test Guideline 870.2600), a 90-day inhalation 
toxicity test (OPPTS Test Guideline 870.3465) would help characterize 
the human health effects of the PMN substance, and a carcinogenicity 
test (OPPTS Test Guideline 870.4200) would help characterize the human 
health effects of the PMN substance.
    CFR citation: 40 CFR 721.10723.

PMN Number P-13-563

    Chemical name: Propylene glycol, alpha isocyanate, omega silane 
(generic).
    CAS number: Claimed confidential.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a chemical intermediate 
for polyurethane polymers. Based on test data on analogous 
diisocyanates, EPA identified concerns for oncogenicity, mutagenicity, 
respiratory and dermal sensitization and lung and mucous membrane 
irritation. For the use described in the PMN, EPA does not expect 
significant occupational or any consumer exposure. 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 without a NIOSH-certified 
particulate respirator (with eye/face protection, when dermal and/or 
ocular exposure is likely) with an APF of at least 10, where there is a 
potential for inhalation exposure; any use other than as an 
intermediate; or any 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 skin 
sensitization test (OPPTS Test Guideline 870.2600); a 90-day inhalation 
toxicity test (OPPTS Test Guideline 870.3465); and a carcinogenicity 
test (OPPTS Test Guideline 870.4200) would help characterize the human 
health effects of the PMN substance.

    CAS numbers: Claimed confidential.
    1. Public comment: The commenter (identity confidential) had 
concerns about the respirators listed as NIOSH-certified respirators 
with an APF of at least 10 meeting the requirements of Sec.  
721.63(a)(4):
    (A) NIOSH-certified power air-purifying respirator with a hood or 
helmet and with appropriate gas/vapor (acid gas, organic vapor, or 
substance specific) cartridges in combination with HEPA filters.
    (B) NIOSH-certified continuous flow supplied-air respirator 
equipped with a loose fitting facepiece, hood, or helmet.
    (C) NIOSH-certified negative pressure (demand) supplied-air 
respirator with a full facepiece.
    The commenter argues these listed respirators have, in fact, APFs 
ranging from 25 to 1,000 and not 10 as required.
    1. EPA response: The proposed SNUR would require notification if 
workers who are reasonably likely to be exposed to the PMN substance by 
inhalation did not use a NIOSH certified respirator with an APF of at 
least 10. Workers who are exposed may use respirators with an APF 
higher than 10. As noted in the response to the comment on P-13-365, 
isocyanates are known dermal and respiratory sensitizers and known to 
cause other health effects. Thus, EPA requires respirators to provide 
protection from all potential exposures. Dermal exposures to 
isocyanates can also possibly cause respiratory

[[Page 850]]

exposures. EPA has modified language in the preamble language to 
indicate that respirators that provide dermal (face/eyes) protection 
are required if dermal and/or ocular exposures are likely. 
Consequently, respirators with a higher APF are also indicated because 
respirators with an APF of 10 do not provide the desired dermal 
protection. The respirators listed were examples of respirators that 
meet the requirements of the SNUR. In the proposed regulatory text, EPA 
has now also included a respirator that has an APF of 10 and does not 
protect against dermal or ocular exposures for scenarios where neither 
dermal nor ocular exposures are likely: NIOSH-certified air-purifying 
half-mask respirator equipped with appropriate gas/vapor cartridges in 
combination with N100, R100, or P100 filters or an appropriate canister 
incorporating N100, R100, or P100 filters.
    2. Public comment: The same commenter provided data that shows that 
diphenylmethane diisocyanate (MDI), ``spills when modeled reached the 
[threshold limit value] TLV concentration 3.8 ft at 38 C (after) 10 h 
had elapsed (and) the [permissible exposure limit] PEL at 38 C reached 
2.2 ft after 10h,'' and that ``MDI diffuses slowly from the spill and 
remains close to the surface of the spill.'' The commenter concludes, 
``It appears unlikely that respiratory protection would be required to 
prevent excessive employee exposure to MDI vapors emitted from the 
spill.'' The commenter contends the use of this data as a surrogate for 
P-13-617, P-13-618, and P-13-619 is conservative because the average 
molecular weight of the individual PMNs is much larger than the 4-4'-
MDI used in this data.
    2. EPA response: EPA acknowledges that this could be the type of 
data used to determine if a worker is reasonably likely to be exposed 
to the PMN substance. However, it does not address every scenario where 
workers are reasonably likely to be exposed. EPA is proposing the SNUR 
to use the notice and comment process to receive and evaluate more 
fully the described data. EPA will then respond to this comment in more 
detail in the final rule along with any additional comments on this 
topic that are received during the notice and comment process.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substances will be as an adhesive. Based on 
test data on analogous diisocyanates, EPA identified concerns for 
dermal and respiratory sensitization. For the use described in the PMN, 
EPA does not expect significant occupational or any consumer inhalation 
exposure as the substances are not applied using a method that 
generates a vapor, mist, or aerosol, nor are they used in a consumer 
product. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substances may present an 
unreasonable risk. EPA has determined, however, that any use of the 
substance without a NIOSH-certified particulate respirator (with eye/
face protection, when dermal and/or ocular exposure is likely) with an 
APF of at least 10, where there is a potential for inhalation exposure; 
any use in consumer products; or any use of the substances involving an 
application method that generates a vapor, mist, or aerosol 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 skin 
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 substances.

PMN Number P-14-60

    Chemical name: 1,1'-methylenebis[isocyanatobenzene], polymer with 
polycarboxylic acids in alkane polyols (generic).
    CAS number: Claimed confidential.
    Public comment: A notice of intent to adversely comment has been 
submitted.
    EPA response: EPA awaits the adverse comment during the open 
comment period for this notice of proposed rule-making.
    Basis for action: The PMN states that the generic (non-
confidential) use of the substance will be as a coating component. 
Based on test data on analogous diisocyanates, EPA identified concerns 
for dermal and respiratory sensitization. As described in the PMN, 
worker exposure will be minimal due to the use of adequate personal 
protective equipment, and EPA does not expect consumer exposure as the 
substance is not used in a consumer product. 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 without a NIOSH-certified 
particulate respirator (with eye/face protection, when dermal and/or 
ocular exposure is likely) with an APF of at least 10, where there is a 
potential for inhalation exposure or any 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)(ii).
    Recommended testing: EPA has determined that the results of a skin 
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.

isocyanatomethylphenyl)amino]carbonyl]--methoxy- and (P-14-268) 
Carbamic acid, N-(3-isoocyanatomethylphenyl)-, 2-[2-(2-
butoxyethoxy)ethoxy]ethyl ester.
    CAS numbers: (P-14-267) 51247-55-3 and (P-14-268) 304855-14-9.
    Basis for action: The PMNs state that the generic (non-
confidential) use of the substances will be as an intermediate. Based 
on test data on analogous isocyanates, EPA identified concerns for 
respiratory and dermal sensitization, and lung and mucous membrane 
irritation. In addition, the Agency identified concerns for 
oncogenicity and mutagenicity based on analog test data. For the use 
described in the PMNs, EPA does not expect significant occupational 
dermal or inhalation exposure, and does not expect consumer exposure as 
the PMNs are not used in consumer products. Therefore, EPA has not 
determined that the proposed manufacturing, processing, or use of the 
substances may present an unreasonable risk. EPA has determined, 
however, that any use of the substance without a NIOSH-certified 
particulate respirator (with eye/face protection, when dermal and/or 
ocular exposure is likely) with an APF of at least 10, where there is a 
potential for inhalation exposure; any use in consumer products; or any 
use of the substances involving an application method that generates a 
vapor, mist, or aerosol may cause serious health effects. Based on this 
information, the PMN substances meet 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 skin 
sensitization test (OPPTS Test Guideline 870.2600), a 90-day inhalation 
toxicity test (OPPTS Test Guideline 870.3465), and a carcinogenicity 
test (OPPTS Test Guideline 870.4200) would help characterize the human 
health effects of the PMN substance.

PMN Number P-14-478

    Chemical name: Carbonic acid, dimethyl ester, polymer with 1,4-
diisocyanatobenzene, 1,6-hexanediol and 1,5-pentanediol.
    CAS numbers: 1558862-08-0.
    Basis for action: The PMN states that the substance will be used to 
make thermoplastic polyurethanes. Based on test data on analogous 
diisocyanates, EPA identified concerns for lung effects and irritation 
to mucous membranes, and for respiratory and dermal sensitization. As 
described in the PMN, EPA does not expect significant occupational 
dermal or inhalation exposure due to use of adequate personal 
protective equipment; and the substance is applied by a method that 
does not generate a vapor, mist, or aerosol. Further, consumer 
exposures are not expected as the PMN substance is not used in consumer 
products. 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 without a NIOSH-certified particulate respirator (with eye/
face protection, when dermal and/or ocular exposure is likely) with an 
APF of at least 10, where there is a potential for inhalation exposure; 
any use of the substance involving an application method that generates 
a vapor, mist, or aerosol; or any use 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)(ii).
    Recommended testing: EPA has determined that the results of a skin 
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 721.10792.

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    For these 13 PMNs subject to these proposed SNURs, EPA determined 
that one or more of the criteria of concern established at 40 CFR 
721.170 were met. For additional discussion of the rationale for the 
SNURs on these chemical substances, see Units II. and IV. of the 
proposed rule.

B. Objectives

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

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

    To establish a significant ``new'' use, EPA must determine that the 
use is not ongoing. The chemical substances subject to this proposed 
rule have undergone premanufacture review. In cases where EPA has not 
received a notice of commencement (NOC) and the chemical substance has 
not been added to the TSCA Inventory, no other person may commence such 
activities without first submitting a PMN. Therefore, for chemical 
substances for which an NOC has not been submitted EPA concludes that 
the designated significant new uses are not ongoing.
    When chemical substances identified in this proposed rule are added 
to the TSCA Inventory, EPA recognizes that, before the rule is 
effective, other persons might engage in a use that has been identified 
as a significant new use. The identities for 10 of the 13 chemical 
substances subject to this proposed rule have been claimed as 
confidential and EPA has received no post-PMN bona fide submissions 
(per 40 CFR 720.25 and Sec.  721.11). Based on this, the Agency 
believes that it is highly unlikely that any of the significant new 
uses described in the regulatory text of this proposed rule are 
ongoing.
    Therefore, EPA designates January 7, 2015 as the cutoff date for 
determining whether the new use is ongoing. Persons who begin 
commercial manufacture or processing of the chemical substances for a 
significant new use identified as of that date would have to cease any 
such activity upon the effective date of the final rule. To resume 
their activities, these persons would have to first comply with all 
applicable SNUR notification requirements and wait until the notice 
review period, including any extensions, expires. If such a person met 
the conditions of advance compliance under Sec.  721.45(h), the person 
would be considered exempt from the requirements of the SNUR. Consult 
the Federal Register document of April 24, 1990 (55 FR 17376) for a 
more detailed discussion of the cutoff date for ongoing uses.

VII. 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 40 CFR 
720.50). However, upon review of PMNs and SNUNs, the Agency has the 
authority to require appropriate testing. Descriptions of tests are 
provided for informational purposes. EPA strongly encourages persons, 
before performing any testing, to consult with the Agency pertaining to 
protocol selection. To access the OCSPP test guidelines referenced in 
this document electronically, please go to http://www.epa.gov/ocspp and 
select ``Test Methods and Guidelines.'' The OECD test guidelines are 
available from the OECD Bookshop at http://www.oecdbookshop.org or 
sourceoecd at http://www.sourceoecd.org.

[[Page 852]]

    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:
    <bullet> Human exposure and environmental release that may result 
from the significant new use of the chemical substances.
    <bullet> Potential benefits of the chemical substances.
    <bullet> Information on risks posed by the chemical substances 
compared to risks posed by potential substitutes.

VIII. SNUN Submissions

    According to Sec.  721.1(c), persons submitting a SNUN must comply 
with the same 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 
submitted on EPA Form No. 7710-25, generated using e-PMN software, and 
submitted to the Agency in accordance with the procedures set forth in 
40 CFR 720.40 and Sec.  721.25. E-PMN software is available 
electronically at http:// www.epa.gov/opptintr/newchems.

IX. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers and processors of the chemical 
substances which were the subject of PMNs P-13-270, P-13-365, P-13-392, 
P-13-393, P-13-471, P-13-563, P-13-617, P-13-618, P-13-619, and P-14-
60, during the development of the direct final rules. EPA's complete 
economic analyses associated with these ten PMNs are available in the 
docket under docket ID numbers EPA-HQ-OPPT-2013-0739, EPA-HQ-OPPT-2014-
0166, and EPA-HQ-OPPT-2014-0277. EPA has evaluated the potential costs 
of establishing SNUN requirements for potential manufacturers and 
processors of the chemical substances which were the subject of PMNs P-
14-267, P-14-268, and P-14-478. EPA's complete economic analysis 
associated with these three PMNs is available in the docket under 
docket ID number EPA-HQ-OPPT-2014-0760.

X. Statutory and Executive Order Reviews

A. Executive Order 12866

    This proposed rule would establish SNURs for 13 chemical substances 
that were the subject of PMNs and a TSCA section 5(e) consent order. 
The Office of Management and Budget (OMB) has exempted these types of 
actions from review under Executive Order 12866, entitled ``Regulatory 
Planning and Review'' (58 FR 51735, October 4, 1993).

B. Paperwork Reduction Act (PRA)

    According to PRA, 44 U.S.C. 3501 et seq., an Agency may not conduct 
or sponsor, and a person is not required to respond to a collection of 
information that requires OMB approval under PRA, unless it has been 
approved by OMB and displays a currently valid OMB control number. The 
OMB control numbers for EPA's regulations in title 40 of the CFR, after 
appearing in the Federal Register, are listed in 40 CFR part 9, and 
included on the related collection instrument or form, if applicable.
    The information collection requirements related to this action have 
already been approved by OMB pursuant to PRA under OMB control number 
2070-0012 (EPA ICR No. 574). This action would 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 SNUR submitted by any small entity would not cost 
significantly more than $8,300.
    A copy of that certification is available in the docket for this 
proposed 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:
    <bullet> A significant number of SNUNs would not be submitted by 
small entities in response to the SNUR.
    <bullet> Submission of the SNUN would not cost any small entity 
significantly more than $8,300.
    Therefore, the promulgation of these SNURs 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 would be impacted by this proposed 
rule. As such, EPA has determined that this proposed rule would not 
impose any enforceable duty, contain any unfunded mandate, or otherwise 
have any effect on small governments subject to the requirements of 
UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 13132

    This 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 would it involve or 
impose any requirements that affect Indian Tribes. Accordingly, the

[[Page 853]]

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 proposed rule is not subject to Executive Order 13211, 
entitled ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001), 
because this 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 would not involve any technical 
standards, NTTAA section 12(d) (15 U.S.C. 272 note), would 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).
