Significant New Use Rules on Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is promulgating significant new use rules (SNURs) under 
section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 38 
chemical substances which were the subject of premanufacture notices 
(PMNs). One of these chemical substances is also subject to a TSCA 
section 5(e) consent order issued by EPA. This action requires persons 
who intend to manufacture, import, or process any of these 38 chemical 
substances for an activity that is designated as a significant new use 
by this rule to notify EPA at least 90 days before commencing that 
activity. The required notification will provide EPA with the 
opportunity to evaluate the intended use and, if necessary, to prohibit 
or limit that activity before it occurs.

DATES: The effective date of this rule is November 19, 2007 without 
further notice, unless EPA receives adverse or critical comments, or 
notice of intent to submit adverse or critical comments before October 
19, 2007. This rule shall be promulgated for purposes of judicial 
review at 1 p.m. (e.s.t.) on October 3, 2007.
    If EPA receives adverse or critical comments, or notice of intent 
to submit adverse or critical comments, on one or more of these SNURs 
before October 19, 2007 EPA will withdraw the relevant sections of this 
direct final rule before its effective date. EPA will then issue a 
proposed SNUR for the chemical substance(s) on which adverse or 
critical comments were received, providing a 30-day period for public 
comment.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this Action Apply to Me?

    You may be potentially affected by this action if you manufacture, 
import, process, or use the chemical substances contained in this rule. 
Potentially affected entities may include, but are not limited to:
     Manufacturers, importers, or processors of one or more 
subject chemical substances (NAICS codes 325 and 324110), e.g., 
Chemical manufacturing and petroleum refineries.

[[Page 53471]]

    This listing is not intended to be exhaustive, but rather provides 
a guide for readers regarding entities likely to be affected by this 
action. Other types of entities not listed in this unit could also be 
affected. The North American Industrial Classification System (NAICS) 
codes have been provided to assist you and others in determining 
whether this action might apply to certain entities. To determine 
whether you or your business may be affected by this action, you should 
carefully examine the applicability provisions in 40 CFR 721.5. If you 
have any questions regarding the applicability of this action to a 
particular entity, consult the technical person listed under FOR 
FURTHER INFORMATION CONTACT.
    This action may also affect certain entities through pre-existing 
import certification and export notification rules under TSCA. Persons 
who import any chemical substance governed by a final SNUR are subject 
to the TSCA section 13 (15 U.S.C. 2612) import certification 
requirements and the corresponding regulations at 19 CFR 12.118 through 
12.127 and 19 CFR 127.28. Those persons must certify that the shipment 
of the chemical substance complies with all applicable rules and orders 
under TSCA, including any SNUR requirements. The EPA policy in support 
of import certification appears at 40 CFR part 707, subpart B. In 
addition, any persons who export or intend to export a chemical 
substance that is the subject of this rule on or after October 19, 2007 
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 e-mail. Clearly mark the part or all of the 
information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as 
CBI and then identify electronically within the disk or CD ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.

II. Background

A. What Action is the Agency Taking?

    EPA is promulgating these SNURs using direct final procedures. 
These SNURs will require persons to notify EPA at least 90 days before 
commencing the manufacture, import, or processing of a chemical 
substance for any activity designated by these SNURs as a significant 
new use. Additional rationale and background to this rule are more 
fully set out in the preamble to EPA's first direct final SNUR 
published in the Federal Register of April 24, 1990 (55 FR 17376). 
Consult that preamble for further information on the objectives, 
rationale, and procedures for SNURs and on the basis for significant 
new use designations, including provisions for developing test data.

B. What is the Agency's Authority for Taking this Action?

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including those listed in TSCA section 5(a)(2). Once 
EPA determines that a use of a chemical substance is a significant new 
use, TSCA section 5(a)(1)(B) requires persons to submit a significant 
new use notice (SNUN) to EPA at least 90 days before they manufacture, 
import, or process the chemical substance for that use. The mechanism 
for reporting under this requirement is established under 40 CFR 721.5.

C. Applicability of General Provisions

    General provisions for SNURs appear under 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 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 on 
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.
    Persons who export or intend to export a chemical substance 
identified in a proposed or final SNUR are subject to the export 
notification provisions of TSCA section 12(b). The regulations that 
interpret TSCA section 12(b) appear at 40 CFR part 707, subpart D. 
Persons who import a chemical substance identified in a final SNUR are 
subject to the TSCA section 13 import certification requirements, 
codified at 19 CFR 12.118 through 12.127 and 19 CFR 127.28. Such 
persons must certify that the shipment of the chemical substance 
complies with all applicable rules and orders under TSCA, including any 
SNUR requirements. The EPA policy in support of the import 
certification appears at 40 CFR part 707, subpart B.

III. Substances Subject to this Rule

    EPA is establishing significant new use and recordkeeping 
requirements for 38 chemical substances under 40 CFR part 721, subpart 
E. In this unit, EPA provides the following information for each 
chemical substance:
     PMN number.
     Chemical name (generic name if the specific name is 
claimed as CBI).
     CAS number (if assigned for non-confidential chemical 
identities).

[[Page 53472]]

     Basis for the section 5(e) consent order, or, for non-5(e) 
SNURs, the basis for the SNUR.
     Toxicity concerns.
     Tests recommended by EPA to provide sufficient information 
to evaluate the chemical substance (see Unit VI. for more information).
     CFR citation assigned in the regulatory text section of 
this rule.
    The specific activities designated as significant new uses are 
listed in the regulatory text section of 40 CFR part 721, subpart E. 
Certain new uses, including production limits and other uses designated 
in the rule are claimed as CBI. The procedure for obtaining 
confidential information is set out in Unit VII.
    This rule includes a SNUR on one PMN substance that is subject to a 
``risk-based'' consent order under TSCA section 5(e)(1)(A)(ii)(I) 
wherein EPA determined that activities associated with the PMN 
substance may present unreasonable risk to health or the environment. 
The consent order requires protective measures to limit exposures or 
otherwise mitigate the potential unreasonable risk. The so-called 
``5(e) SNUR'' on this substance is promulgated pursuant to 40 CFR 
721.160, and is based on and consistent with the provisions in the 
underlying consent order. The SNUR designates as a ``significant new 
use'' the absence of the protective measures required in the consent 
order.
    This rule also includes SNURs on 37 PMN substances that are not 
subject to consent orders under TSCA section 5(e). In these cases, EPA 
did not find that the use scenario described in the PMN triggered the 
determinations set forth under section 5(e) of TSCA. EPA, however, does 
believe that certain changes from the use scenario described in the PMN 
could result in increased exposures, thereby constituting a 
``significant new use.'' These so-called ``non-5(e) SNURs'' are 
promulgated pursuant to 40 CFR 721.170. EPA has determined that every 
activity designated as a ``significant new use'' in all the non-5(e) 
SNURs issued under 40 CFR 721.170 satisfies the two requirements 
stipulated in Sec.  721.170(c)(2), i.e., these significant new use 
activities, ``(i) are different from those described in the 
premanufacture notice for the substance, including any amendments, 
deletions, and additions of activities to the premanufacture notice, 
and (ii) may be accompanied by changes in exposure or release levels 
that are significant in relation to the health or environmental 
concerns identified'' for the PMN substance.
PMN Numbers P-01-759 and P-05-555
Chemical name: Dodecandioic acid, 1, 12-dihydrazide.
CAS number: 4080-98-2.
Basis for action: The PMNs state that the generic (non-confidential) 
uses of the substance will be as a raw material for coating and 
sealants and as a curing agent. Based on molecular structure and test 
data on analogous substances, EPA has identified health concerns for 
carcinogenicity, developmental toxicity, and irritation to mucous 
membranes. Also, based on test data on the PMN substance, EPA has 
identified concerns for dermal sensitization. As described in the PMNs 
and accompanying Material Safety Data Sheets, workers will be warned 
that the substance may cause dermal sensitization and will wear gloves 
and National Institute for Occupational Safety and Health (NIOSH) 
approved respirators with an assigned protection factor (APF) of 50 or 
greater. Based on adequate personal protective equipment and hazard 
communication, significant worker exposure is unlikely. Further, 
consumer use is not expected. Therefore, EPA has not determined that 
the proposed manufacturing, processing, or use of the substance may 
present an unreasonable risk. EPA has determined, however, that use of 
the substance without workers wearing gloves and a respirator, and 
without an appropriate hazard communication program, may cause serious 
human health effects. Respirators must provide a NIOSH APF of at least 
50. The following NIOSH-approved respirators meet the minimum 
requirement for Sec.  721.63(a)(4): Air-purifying, tight-fitting full-
face respirator equipped with N100 (if oil aerosols absent), R100, or 
P100 filters; powered air-purifying respirator equipped with a tight-
fitting full facepiece and High Efficiency Particulate Air (HEPA) 
filters; supplied air respirator operated in pressure demand or 
continuous flow mode and equipped with a tight-fitting full facepiece. 
Because the substance is a dermal sensitizer and irritates mucous 
membranes, half-face respirators do not provide adequate protection. 
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 90-day 
oral toxicity test in rats (OPPTS 870.3100 test guideline) and a 
mammalian erythrocyte micronucleus test (OPPTS 870.5395 test guideline) 
would help characterize the human health effects of the PMN substance.
CFR citation: 40 CFR 721.10057.
PMN Numbers P-03-546, P-03-550, and P-03-551
Chemical names: (P-03-546) Reaction product of alkylphenol, aromatic 
cyclicamine, alkyl diglycidyl dibenzene, and formaldehyde (generic); 
(P-03-550) Reaction product of alkylphenyl glycidyl ether, 
polyalkylenepolyamine, and alkyl diglycidyl dibenzene (generic); and 
(P-03-551) Reaction product of alkylphenyl glycidyl ether, 
polyalkylenepolyamine, alkyl diglycidyl dibenzene, and 
polyalkylcyclicdiamine (generic).
CAS numbers: Not available.
Basis for action: The PMNs state that the substances will be used as 
epoxy curing agents. Based on test data on structurally analogous 
polycationic polymers, EPA is concerned that toxicity to aquatic 
organisms may occur at concentrations at or above 20 parts per billion 
(ppb) of the PMN substances in surface waters. As described in the 
PMNs, the substances are not released to surface waters. 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 uses of the substances resulting in release to surface 
waters may cause significant adverse environmental effects. Based on 
this information, the PMN substances meet the concern criteria at Sec.  
721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of the 
following tests would help characterize the environmental effects of 
the PMN substances: A fish acute toxicity test, freshwater and marine 
(OPPTS 850.1075 test guideline (public draft)); a fish acute toxicity 
test mitigated by humic acid (OPPTS 850.1085 test guideline (public 
draft)); an aquatic invertebrate acute toxicity test, freshwater 
daphnids (OPPTS 850.1010 test guideline (public draft)); and an algal 
toxicity test, tiers I and II (OPPTS 850.5400 test guideline (public 
draft)).
CFR citations: 40 CFR 721.10058 (P-03-546); 40 CFR 721.10059 (P-03-
550); and 40 CFR 721.10060 (P-03-551).
PMN Number P-04-341
Chemical name: Pentane, 1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-
(trifluoromethyl)-.
CAS number: 132182-92-4.
Basis for action: The PMN states that the substance will be used as a 
solvent coating and heat transfer fluid. EPA has identified health and 
environmental concerns because the substance is potentially a 
persistent, bio-accumulative, and toxic (PBT) chemical, consistent with 
the New Chemical Program's PBT Category (64 FR 60194; November 4, 
1999). EPA estimates that the PMN substance will persist in the 
environment more than six months and

[[Page 53473]]

estimates a bioaccumulation factor of greater than or equal to 1,000, 
based on test data indicating a fish bioaccumulation factor of 3.2 and 
a log Kow of 4.70. As described in the PMN, the substance is 
not released to surface water. 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 
release of the PMN substance to surface waters may cause significant 
adverse environmental effects, since the PMN substance has been 
characterized by EPA as a PBT. 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 the tiered 
testing as described in the New Chemicals Program's PBT Category would 
help characterize the PBT attributes of the substance. EPA has 
determined that the results of an algal toxicity test, tiers I and II 
(OPPTS 850.5400 test guideline (public draft)), a fish early-life stage 
toxicity test (OPPTS 850.1400 test guideline (public draft)), and a 
daphnid chronic toxicity test (OPPTS 850.1300 test guideline (public 
draft)) would further characterize the environmental effects of the PMN 
substance.
CFR citation: 40 CFR 721.10061.
PMN Number P-04-627
Chemical name: 2,5-Furandione, polymer with oxybis[propanol], benzoate.
CAS number: 103458-14-6.
Basis for action: The PMN states that the generic (non-confidential) 
use of the substance will be as a spray-applied filled backing resin. 
Based on test data on structurally similar acrylates and esters, EPA is 
concerned that toxicity to aquatic organisms may occur at 
concentrations at or above 9 ppb of the PMN substance in surface 
waters. As described in the PMN, the substance is not released to 
surface waters. Therefore, EPA has not determined that the proposed 
manufacturing, processing, or use of the substances may present an 
unreasonable risk. EPA has determined, however, that other uses of the 
substances resulting in release to surface waters may cause significant 
adverse environmental effects. Based on this information, the PMN 
substance meets the concern criteria at Sec.  721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of a fish 
acute toxicity test, freshwater and marine (OPPTS 850.1075 test 
guideline (public draft)), an aquatic invertebrate acute toxicity test, 
freshwater daphnids (OPPTS 850.1010 test guideline (public draft)), and 
an algal toxicity test, tiers I and II (OPPTS 850.5400 test guideline 
(public draft)) would help characterize the environmental effects of 
the PMN substance.
CFR citation: 40 CFR 721.10062.
PMN Number P-04-792
Chemical name: Halo substituted hydroxy nitrophenyl amide (generic).
CAS number: Not available.
Basis for action: The PMN states that generic (non-confidential) use of 
the substance will be as a chemical intermediate. Based on test data on 
structurally analogous phenols, EPA is concerned that toxicity to 
aquatic organisms may occur at concentrations at or above 2 ppb of the 
PMN substance in surface waters. As described in the PMN, the substance 
is not released to surface waters. Therefore, EPA has not determined 
that the proposed manufacturing, processing, or use of the substance 
may present an unreasonable risk. EPA has determined, however, that 
other uses of the substance resulting in release to surface waters may 
cause significant adverse environmental effects. Based on this 
information, the PMN substance meets the concern criteria at Sec.  
721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of the 
following tests would help characterize the environmental effects of 
the PMN substance: An algal toxicity test, tiers I and II (OPPTS 
850.5400 test guideline (public draft)); a fish early-life stage 
toxicity test (OPPTS 850.1400 test guideline (public draft)); a daphnid 
chronic toxicity test (OPPTS 850.1300 test guideline (public draft)); 
and either a porous pot test (OPPTS 835.3220 test guideline) or an 
aerobic sewage treatment test (Organization for Economic Cooperation 
and Development (OECD) 303A test guideline). The algal toxicity study 
should be performed using the static method with measured 
concentrations and the fish and daphnid tests should be performed using 
the flow-through method with measured concentrations.
CFR citation: 40 CFR 721.10063.
PMN Number P-04-909
Chemical name: 2-Propenoic acid, 2-[2-(ethenyloxy)ethoxy]ethyl ester.
CAS number: 86273-46-3.
Effective date of section 5(e) consent order: 6-26-2006.
Basis for section 5(e) consent order: The PMN states the substance will 
be used as an ultraviolet-curable monomer for polymerization. The order 
was issued under section 5(e)(1)(A)(i) and (e)(1)(A)(ii)(I) of TSCA, 
based on a finding that this substance may present an unreasonable risk 
of injury to human health. To protect against this risk, the consent 
order requires use of gloves demonstrated by testing to be impervious 
(North Butyl Black gloves and T-1 Dailove Ethylene Vinylalcohol 
Copolymer Laminated Blue gloves have satisfied this requirement) and a 
hazard communication program. The SNUR designates as a `significant new 
use' the absence of these protective measures.
Toxicity concern: Based on test data on chemicals analogous to the PMN 
substance, EPA has concerns that the PMN substance may cause 
developmental toxicity, mutagenicity, reproductive toxicity, and 
oncogenicity. Also, EPA has health concerns for sensitization based on 
submitted test data on the PMN substance and via analogy to TSCA 
section 8(e) submission number 8EHQ-1092-11387, skin irritation and 
kidney toxicity concerns based on data for a bismethacrylate analog 
TSCA section 8(e) submission number 8EHQ-0695-13474, and skin cancer 
concerns (if exposed individuals are not protected from skin damage 
from the irritant properties of the chemical) based on male mouse 
chronic dermal toxicity test data for an analog, For Your Information 
(FYI) submission number FYI-0691-01262.
Recommended testing: EPA has determined that the results of a combined 
repeated dose toxicity test with reproduction/developmental screening 
(OPPTS 870.3650 test guideline) would help characterize the human 
health effects of the PMN substance. The test should be done in rats, 
through the oral route of exposure, and be modified to dose for 70 
days, an entire sperm cycle, before mating occurs. The PMN submitter 
has agreed not to exceed the production volume limit without performing 
this test.
CFR citation: 40 CFR 721.10064.
PMN Numbers P-04-961 and P-04-962
Chemical names: (P-04-961) 1-Tetradecanesulfonic acid,

the PMN substances, EPA is concerned that toxicity to aquatic organisms 
may occur at concentrations at or above 30 ppb of the PMN substances in 
surface waters. As described in the consolidated PMNs, the substances 
will not be released to surface waters. 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 other uses of the substances resulting in release to 
surface waters may cause significant adverse environmental effects. 
Based on this information, the PMN substances meet the concern criteria 
at Sec.  721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of an algal 
toxicity test, tiers I and II (OPPTS 850.5400 test guideline (public

Chemical name: Substituted benzenediamine (generic).
CAS number: Not available.
Basis for action: The PMN states that the generic (non-confidential) 
use of the substance will be as a chemical intermediate that will be 
destroyed during use. Based on test data on analogous chemicals, EPA is 
concerned that toxicity to aquatic organisms may occur at 
concentrations above 2 ppb of the PMN substance in surface waters. As 
described in the PMN, releases of the PMN substance are not expected to 
result in surface water concentrations above 2 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 other uses of the substance resulting in surface water 
concentrations above 2 ppb may cause significant adverse environmental 
effects. Based on this information, the PMN substance meets the concern 
criteria at Sec.  721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of the 
following tests would help characterize the environmental effects of

Chemical name: 3H-1,2,4-Triazol-3-one, 1,2-dihydro-.
CAS number: 930-33-6.
Basis for action: The PMNs state that the substance will be used as a 
chemical intermediate. Based on test data on 1,2,4-Triazole, EPA has 
concern for developmental toxicity. Also, based on test data on 
structural analogues, EPA is concerned that toxicity to aquatic 
organisms may occur at concentrations at or above 20 ppb of the PMN 
substance in surface waters. As described in the PMNs, the substance 
will not be released to surface water and worker exposure will be 
minimal due to adequate personal protective equipment. Therefore, EPA 
has not determined that the proposed manufacturing, processing, or use 
of the substance may present an unreasonable risk. EPA has determined, 
however, that use of the substance resulting in release to surface 
waters or use of the substance without appropriate hazard communication 
and worker respiratory protection may cause significant adverse 
environmental and human health effects. Based on this information, the 
PMN substance meets the concern criteria at Sec.  721.170 (b)(3)(ii) 
and(b)(4)(ii).
Recommended testing: EPA has determined that the results of the 
following tests would help characterize the environmental and health 
effects of the PMN substance: A ready biodegradability test using any 
of the six methods (OPPTS 835.3110 test guideline); a porous pot test 
(OPPTS 835.3220 test guideline); a fish acute toxicity test, freshwater 
and marine (OPPTS 850.1075 test guideline (public draft)); an aquatic 
invertebrate acute toxicity test, freshwater daphnids (OPPTS 850.1010 
test guideline (public draft)); an algal toxicity test, tiers I and II

at Sec.  721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of an 
activated sludge sorption isotherm test (OPPTS 835.1100 test 
guideline), a fish early-life stage toxicity test (OPPTS 850.1400 test 
guideline (public draft)), and a daphnid chronic toxicity test (OPPTS 
850.1300 test guideline (public draft)) would help characterize the 
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.10084.
PMN Number P-06-232
Chemical name: Substituted polyaryl sulfonium polyhalide phosphate salt 
(generic).
CAS number: Not available.
Basis for action: The PMN states that the substance will be used as a 
photo initiator used in photo-curable compositions. Based on test data 
on the PMN substance, EPA has concerns for widespread systemic toxicity 
in most organ systems, persistent eye irritation, male reproductive 
toxicity, and developmental-neurotoxicity in off-spring (caused by 
maternal thyroid toxicity) for the PMN material. As described in the 
PMN, worker inhalation and eye exposure are not expected. Therefore, 
EPA has not determined that the proposed manufacturing, processing, or 
use of the substance may present an unreasonable risk. EPA has 
determined, however, that domestic manufacture or the use of the 
substance other than as described in the PMN may cause serious health 
effects. Based on this information, the PMN substance meets the concern 
criteria at Sec.  721.170(b)(3)(i).
Recommended testing: EPA has determined that the results of a combined 
repeated dose toxicity study with the reproduction/developmental 
screening test (OPPTS 870.3650 test guideline) would help characterize 
the human health effects of the PMN substance.
CFR citation: 40 CFR 721.10085.
PMN Number P-06-295
Chemical name: Ethane, 2-(difluoromethoxy)-1,1,1-trifluoro-.
CAS number: 1885-48-9.
Basis for action: The PMN states that the generic (non-confidential) 
use of the substance will be as an intermediate. Based on test data on 
structural analogues, EPA has concerns for solvent neurotoxicity, 
solvent irritation, and developmental toxicity for the PMN substance. 
As described in the PMN, only limited worker dermal and

[[Page 53478]]

inhalation exposures are expected. Therefore, EPA has not determined 
that the proposed manufacturing, processing, or use of the substance 
may present an unreasonable risk. EPA has determined, however, that use 
of the substance other than as an intermediate with workers wearing 
impervious gloves may cause serious human 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 90-day 
inhalation toxicity study (OPPTS 870.3465 test guideline) with a 
neurotoxicity functional observational battery (National Technical 
Information Service (NTIS) PB 91-154617) and neuropathology would help 
characterize the human health effects of the PMN substance.
CFR citation: 40 CFR 721.10086.
PMN Number P-06-332
Chemical name: Substituted alkyl phosphine oxide (generic).
CAS number: Not available.
Basis for action: The PMN states that the generic (non-confidential) 
use of the substance will be as a bonded flame retardant. Based on test 
data on analogous alkyl and aryl phosphates, EPA believes the PMN 
substance may cause delayed neurotoxicity in humans. At the production 
volume stated in the PMN, significant human exposure is unlikely. 
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 increased importation or production 
volumes may result in increased exposure to the PMN substance which may 
cause significant adverse human 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 an acute 
and 28-day delayed neurotoxicity of organophosphorus substances study 
(OPPTS 870.6100 test guideline) would help characterize the human 
health effects of the PMN substance.
CFR citation: 40 CFR 721.10087.
PMN Number P-07-283
Chemical name: Thiophene, 2,5-dibromo-3-hexyl-.
CAS number: 116971-11-0.
Basis for action: The PMN states that the substance will be used as a 
reactive intermediate monomer for use in manufacturing a p-type organic 
semiconductor polymer. The polymer will be used in printed organic 
electronics applications. Based on structure activity relationship 
analyses for thiophenes, EPA is concerned that toxicity to aquatic 
organisms may occur at concentrations above 1 ppb of the PMN substance 
in surface waters. At the production volume stated in the PMN, releases 
of the PMN substance are not expected to result in surface water 
concentrations above 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 increased 
production or importation volumes or other uses of the substance 
resulting in surface water concentrations above 1 ppb may cause 
significant adverse environmental effects. Based on this information, 
the PMN substance meets the concern criteria at Sec.  
721.170(b)(4)(ii).
Recommended testing: EPA has determined that the results of an algal 
toxicity test, tiers I and II (OPPTS 850.5400 test guideline (public 
draft)), a fish early-life stage toxicity test (OPPTS 850.1400 test 
guideline (public draft)), and a daphnid chronic toxicity test (OPPTS 
850.1300 test guideline (public draft)) would help characterize the 
environmental effects of the PMN substance. The fish and daphnid tests 
should use flow-through conditions and measured concentrations.
CFR citation: 40 CFR 721.10088.

IV. Objectives and Rationale of the Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are subject to these SNURs, EPA concluded that for one of the 38 
chemical substances, regulation was warranted under section 5(e) of 
TSCA, pending the development of information sufficient to make a 
reasoned evaluation of the health effects of the chemical substance. 
The basis for such findings is outlined in Unit III. Based on these 
findings, a TSCA section 5(e) consent order requiring the use of 
appropriate exposure controls was negotiated with the PMN submitter; 
the SNUR provisions for this chemical substance listed in this document 
are consistent with the provisions of the TSCA section 5(e) consent 
order.
    In the other 37 cases for which the proposed uses are not regulated 
under a TSCA section 5(e) consent order, EPA determined that one or 
more of the criteria of concern established at 40 CFR 721.170 were met, 
as discussed in Unit III.

B. Objectives

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

V. Direct Final Procedures

    EPA is issuing these SNURs as a direct final rule, as described in 
40 CFR 721.160(c)(3) and 721.170(d)(4). In accordance with 40 CFR 
721.160(c)(3)(ii) and 721.170(d)(4)(i), this rule will be effective 
November 19, 2007, unless EPA receives a written notice by October 19, 
2007 of adverse or critical comments, or notice of intent to submit 
adverse or critical comments, on EPA's action. If EPA receives such a 
notice, EPA will publish a document to withdraw the direct final SNUR 
for the specific chemical substance to which the adverse or critical 
comments apply. EPA will then propose a SNUR for the specific chemical 
substance providing a 30-day comment period.
    This action establishes SNURs for a number of chemical substances. 
Any person who submits adverse or critical comments or notice of intent 
to submit adverse or critical comments, must identify the chemical 
substance and the new use to which it applies. EPA will not withdraw a 
SNUR for a chemical substance not identified in a notice.

[[Page 53479]]

VI. Test Data and Other Information

    EPA recognizes that TSCA section 5 does not require developing any 
particular test data before submission of a SNUN. 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. However, 
upon review of PMNs and SNUNs, the Agency has the authority to require 
appropriate testing. In cases where EPA issued a TSCA section 5(e) 
consent order that requires or recommends certain testing, Unit III. 
lists those tests. Unit III. also lists recommended testing for the 
chemical substances that would be covered by the non-5(e) SNURs. 
Descriptions of tests are provided for informational purposes. EPA 
strongly encourages persons, before performing any testing, to consult 
with the Agency pertaining to protocol selection. Many test guidelines 
are now available on the Internet at http://www.epa.gov/opptsfrs/home/guidelin/htm. OECD test guidelines are available from the OECD Bookshop 
(http://www.oecdbookshop.org) or Source OECD (http://www.sourceoecd.org).
    In the TSCA section 5(e) consent order for the chemical notified 
under P-04-909, EPA has established a production volume limit which 
cannot be exceeded unless the PMN submitter first submits the results 
of toxicity tests that would permit a reasoned evaluation of the 
potential risks posed by this chemical substance. Under recent consent 
orders, the PMN submitter is required to submit the results of the 
required studies at least 14 weeks (earlier consent orders required 
submissions at least 12 weeks) before reaching the specified production 
limit. The tests specified in the TSCA section 5(e) consent order are 
included in Unit III. The SNUR contains the same production volume 
limit as the consent order. Exceeding this production limit is defined 
as a significant new use. Persons who intend to exceed the production 
limit must notify the Agency by submitting a SNUN at least 90 days in 
advance.
    The recommended tests may not be the only means of addressing the 
potential risks of the chemical substances regulated under this rule. 
However, SNUNs submitted for significant new uses 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 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:
    1. Human exposure and environmental release that may result from 
the significant new use of the chemical substances.
    2. Potential benefits of the chemical substances.
    3. Information on risks posed by the chemical substances compared 
to risks posed by potential substitutes.

VII. Procedural Determinations

    EPA is establishing through this rule certain significant new uses 
which have been claimed as CBI subject to Agency confidentiality 
regulations at 40 CFR part 2. EPA is required to keep this information 
confidential to protect the CBI of the original PMN submitter. EPA 
promulgated a procedure to deal with the situation where a specific 
significant new use is CBI. This procedure appears in 40 CFR 
721.1725(b)(1) and is similar to that in Sec.  721.11 for situations 
where the chemical identity of the chemical substance subject to a SNUR 
is CBI. This procedure is cross-referenced in each of these SNURs that 
include specific significant new uses that are CBI.
    A manufacturer or importer may request EPA to determine whether a 
proposed use would be a significant new use under this rule. Under the 
procedure in Sec.  721.1725(b)(1), a manufacturer or importer must show 
that it has a bona fide intent to manufacture or import the chemical 
substance and must identify the specific use for which it intends to 
manufacture or import the chemical substance. If EPA concludes that the 
person has shown a bona fide intent to manufacture or import the 
chemical substance, EPA will tell the person whether the use identified 
in the bona fide submission would be a significant new use under the 
rule. Since most of the chemical identities of the chemical substances 
subject to these SNURs are also CBI, manufacturers and processors can 
combine the bona fide submission under the procedure in Sec.  
721.1725(b)(1) with that under Sec.  721.11 into a single step.
    If a manufacturer or importer is told that the production volume 
identified in the bona fide submission would not be a significant new 
use, i.e., it is below the level that would be a significant new use, 
that person can manufacture or import the chemical substance as long as 
the aggregate amount does not exceed that identified in the bona fide 
submission to EPA. If the person later intends to exceed that volume, a 
new bona fide submission would be necessary to determine whether that 
higher volume would be a significant new use. EPA is considering 
whether to adopt a special procedure for use when CBI production volume 
is designated as a significant new use. Under such a procedure, a 
person showing a bona fide intent to manufacture or import the chemical 
substance, under the procedure described in Sec.  721.11, would 
automatically be informed of the production volume that would be a 
significant new use. Thus, the person would not have to make multiple 
bona fide submissions to EPA for the same chemical substance to remain 
in compliance with the SNUR, as could be the case under the procedures 
in Sec.  721.1725(b)(1).

VIII. Applicability of 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. The chemical substances subject to this rule have 
recently undergone premanufacture review. A TSCA section 5(e) consent 
order has been issued for one chemical substance and the notice 
submitter is prohibited by the TSCA section 5(e) consent order from 
undertaking activities which EPA is designating as significant new 
uses. In cases where EPA has not received a notice of commencement 
(NOC) and the chemical substance has not been added to the TSCA 
Inventory, no other person may commence such activities without first 
submitting a PMN. For chemical substances for which an NOC has not been 
submitted at this time, EPA has concluded that the uses are not 
ongoing. However, EPA recognizes in cases when chemical substances 
identified in this SNUR are added to the TSCA Inventory prior to the 
effective date of the rule, the chemical substances may be 
manufactured, imported, or processed by other persons for a significant 
new use as defined in this rule before the effective date of the rule. 
However, 26 of the 38 chemical substances contained in this rule have 
CBI chemical identities, and since EPA has received a limited number of 
post-PMN bona fide submissions (per 40 CFR 720.25 and 721.11), the 
Agency believes that it is highly unlikely that any of the significant 
new uses described in the following regulatory text are ongoing. EPA 
solicits comments on whether any of the uses described as significant 
new uses are ongoing.
    As discussed in the Federal Register of April 24, 1990 (55 FR 
17376), EPA has decided that the intent of section 5(a)(1)(B) of TSCA 
is best served by designating a use as a significant new

[[Page 53480]]

use as of the date of publication of this direct final rule rather than 
as of the effective date of the rule. If uses begun after publication 
were considered ongoing rather than new, it would be difficult for EPA 
to establish SNUR notice requirements because a person could defeat the 
SNUR by initiating the significant new use before the rule became 
final, and then argue that the use was ongoing as of the effective date 
of the final rule. Thus, persons who begin commercial manufacture, 
import, or processing of the chemical substances regulated through this 
SNUR will have to cease any such activity before the effective date of 
this rule. To resume their activities, these persons would have to 
comply with all applicable SNUR notice requirements and wait until the 
notice review period, including all extensions, expires.
    EPA has promulgated provisions to allow persons to comply with this 
SNUR before the effective date. If a person 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.

IX. SNUN Submissions

    EPA recommends that submitters consult with the Agency prior to 
submitting a SNUN to discuss what data may be useful in evaluating a 
significant new use. Discussions with the Agency prior to submission 
can afford ample time to conduct any tests that might be helpful in 
evaluating risks posed by the substance. 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 mailed to the Environmental Protection Agency, OPPT 
Document Control Office (7407M), 1200 Pennsylvania Ave., NW., 
Washington, DC 20460-0001. Information must be submitted in the form 
and manner set forth in EPA Form No. 7710-25. This form is available 
from the Environmental Assistance Division (7408M), 1200 Pennsylvania 
Ave., NW., Washington, DC 20460-0001 (see 40 CFR 721.25 and 720.40). 
Forms and information are also available electronically at http://www.epa.gov/opptintr/newchems/pubs/pmnforms.htm.

X. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers, importers, and processors of 
the chemical substances subject to this rule. EPA's complete economic 
analysis is available in the public docket.

XI. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866, entitled Regulatory Planning and 
Review (58 FR 51735, October 4, 1993), the Office of Management and 
Budget (OMB) has determined that proposed or final SNURs are not a 
``significant regulatory action'' subject to review by OMB, because 
they do not meet the criteria in section 3(f) of the Executive order.

B. Paperwork Reduction Act

    According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et 
seq., an Agency may not conduct or sponsor, and a person is not 
required to respond to a collection of information that requires OMB 
approval under the 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 the 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

    Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA) 
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation 
of this SNUR will not have a significant adverse economic impact on a 
substantial number of small entities. The rationale supporting this 
conclusion is as follows. A SNUR applies to any person (including small 
or large entities) who intends to engage in any activity described in 
the rule as a ``significant new use.'' By definition of the word 
``new,'' and based on all information currently available to EPA, it 
appears that no small or large entities presently engage in such 
activity. Since a SNUR only requires that any person who intends to 
engage in such activity in the future must first notify EPA by 
submitting a SNUN, no economic impact will even occur until someone 
decides to engage in those activities. Although some small entities may 
decide to conduct such activities in the future, EPA cannot presently 
determine how many, if any, there may be. However, EPA's experience to 
date is that, in response to the promulgation of over 1,000 SNURs, the 
Agency receives on average only 10 notices per year. Of those SNUNs 
submitted, none appear to be from small entities in response to any 
SNUR. In addition, the estimated reporting cost for submission of a 
SNUN (see Unit IX.), are minimal regardless of the size of the firm. 
Therefore, EPA believes that the potential economic impacts of 
complying with this SNUR are not expected to be significant or 
adversely impact a substantial number of small entities. In a SNUR that 
published on June 2, 1997 (62 FR 29684) (FRL-5597-1), the Agency 
presented it's general determination that proposed and final SNURs are 
not expected to have a significant economic impact on a substantial 
number of small entities, which was provided to the Chief Counsel for 
Advocacy of the Small Business Administration.

D. Unfunded Mandates Reform Act

    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 rulemaking. 
As such, EPA has determined that this regulatory action does not impose 
any enforceable duty, contain any unfunded mandate, or otherwise have 
any affect on small governments subject to the requirements of sections 
202, 203, 204, or 205 of the

[[Page 53481]]

Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4).

E. Executive Order 13132: Federalism

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

F. Executive Order 13175: Consultation and Coordination with Indian 
Tribal Governments

    This rule does not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This does 
not significantly or 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 6, 2000), do not apply to this rule.

G. Executive Order 13045: Protection of Children from Environmental 
Health Risks and Safety Risks

    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: Actions that Significantly Affect Energy 
Supply, Distribution, or Use

    This 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.

I. National Technology Transfer Advancement Act

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

J. Executive Order 12898: Federal Actions to Address Environmental 
Justice in Minority Populations and Low-Income Populations

    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).

K. Executive Order 12630: Governmental Actions and Interference with 
Constitutionally Protected Property Rights (Takings)

    EPA has complied with Executive Order 12630, entitled Governmental 
Actions and Interference with Constitutionally Protected Property 
Rights (53 FR 8859, March 15, 1988), by examining the takings 
implications of this rule in accordance with the ``Attorney General's 
Supplemental Guidelines for the Evaluation of Risk and Avoidance of 
Unanticipated Takings'' issued under the Executive order.

L. Executive Order 12988: Civil Justice Reform

    In issuing this rule, EPA has taken the necessary steps to 
eliminate drafting errors and ambiguity, minimize potential litigation, 
and provide a clear legal standard for affected conduct, as required by 
section 3 of Executive Order 12988, entitled Civil Justice Reform (61 
FR 4729, February 7, 1996).

XII. Congressional Review Act

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

2. By adding new Sec.  721.10057 to subpart E to read as follows:


Sec.  721.10057  Dodecanedioic acid, 1, 12-dihydrazide.

    (a) Chemical substance and significant new uses subject to 
reporting. (1) The chemical substance identified as dodecanedioic acid, 
1, 12-dihydrazide (PMNs P-01-759 and P-05-555; CAS No. 4080-98-2) is 
subject to reporting under this section for the significant new uses 
described in paragraph (a)(2) of this section.
    (2) The significant new uses are:
    (i) Protection in the workplace. Requirements as specified in Sec.  
721.63 (a)(1), (a)(2)(i), (a)(3), (a)(4), (a)(5), (a)(6), (b), and (c). 
Respirators must provide a National Institute for Occupational Safety 
and Health (NIOSH) assigned protection factor (APF) of at least 50. The 
following NIOSH-approved respirators meet the minimum requirement for 
Sec.  721.63(a)(4): Air-purifying, tight-fitting full-face respirator 
equipped with N100 (if oil aerosols absent), R100, or P100 filters; 
powered air-purifying respirator equipped with a tight-fitting full 
facepiece and High Efficiency Particulate Air (HEPA) filters; supplied
