Significant New Uses of Certain Chemical Substances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is promulgating significant new use rules (SNURs) under 
section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 163 
chemical substances which were the subject of premanufacture notices 
(PMNs) and subject to TSCA section 5(e) consent orders issued by EPA. 
Today's action requires persons who intend to manufacture, import, or 
process these substances for a significant new use to notify EPA at 
least 90 days before commencing the manufacturing or processing of the 
substance for a use designated by this SNUR as a significant new use. 
The required notice will provide EPA with the opportunity to evaluate 
the intended use, and if necessary, to prohibit or limit that activity 
before it occurs. EPA is promulgating this SNUR using direct final 
procedures.

DATES: The effective date of this rule is March 23, 1998. This rule 
shall be promulgated for purposes of judicial review at 1 p.m. (e.s.t.) 
on February 5, 1998.
    If EPA receives notice before February 23, 1998 that someone wishes 
to submit adverse or critical comments on EPA's action in establishing 
a SNUR for one or more of the chemical substances subject to this rule, 
EPA will withdraw the SNUR for the substance for which the notice of 
intent to comment is received and will issue a proposed SNUR providing 
a 30-day period for public comment.

ADDRESSES: Each comment or notice of intent to submit adverse or 
critical comment must bear the docket control number OPPTS-50628 and 
the name(s) of the chemical substance(s) subject to the comment. All 
comments should be sent in triplicate to: OPPT Document Control Officer 
(7407), Office of Pollution Prevention and Toxics, Environmental 
Protection Agency, 401 M Street, SW., Room G-099, East Tower, 
Washington, DC 20460.
    Comments and data may also be submitted electronically to: 
<a href="/cdn-cgi/l/email-protection#ef809f9f9bc1818c868caf8a9f8e828e8683c18a9f8ec1888099"><span class="__cf_email__" data-cfemail="b9d6c9c9cd97d7dad0daf9dcc9d8d4d8d0d597dcc9d897ded6cf">[email protected]</span></a>. Follow the instructions under Unit X of this 
document. No Confidential Business Information (CBI) should be 
submitted through e-mail.
    All comments which contain information claimed as CBI must be 
clearly marked as such. Three sanitized copies of any comments 
containing information claimed as CBI must also be submitted and will 
be placed in the public record for this rulemaking. Persons submitting 
information on any portion of which they believe is entitled to 
treatment as CBI by EPA must assert a business confidentiality claim in 
accordance with 40 CFR 2.203(b) for each portion. This claim must be 
made at the time that the information is submitted to EPA . If a 
submitter does not assert a confidentiality claim at the time of 
submission, EPA will consider this as a waiver of any confidentiality 
claim and the information may be made available to the public by EPA 
without further notice to the submitter.

SUPPLEMENTARY INFORMATION:
    Electronic Availability: Electronic copies of this document are 
available from the EPA Home Page at the Federal Register-Environmental 
Documents entry for this document under ``Laws and Regulations'' 
(http://www.epa.gov/fedrgstr/).
    This SNUR will require persons to notify EPA at least 90 days 
before commencing manufacturing or processing a substance for any 
activity designated by this SNUR as a significant new use. The 
supporting rationale and background to this rule are more fully set out 
in the preamble to EPA's first direct final SNURs 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 the rules and on the basis for significant new use designations 
including provisions for developing test data.

I. Authority

    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, section 5(a)(1)(B) of TSCA requires persons to submit a notice to 
EPA at least 90 days before they manufacture, import, or process the 
substance for that use. The mechanism for reporting under this 
requirement is established under 40 CFR 721.10.

II. 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. 
Persons subject to this SNUR must comply with the same notice 
requirements and EPA regulatory procedures as submitters of PMNs under 
section 5(a)(1)(A) of TSCA. In particular, these requirements include 
the information submission requirements of TSCA section 5(b) and 
5(d)(1), the exemptions authorized by section 5 (h)(1), (2), (3), and 
(5), and the regulations at 40 CFR part 720. Once EPA receives a SNUR 
notice, 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 SNUR 
notice. 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 intend to export a substance identified in a proposed 
or final SNUR are subject to the export notification provisions of TSCA 
section 12(b). The regulations that interpret section 12(b) appear at 
40 CFR part 707. Persons who intend to import a chemical substance 
identified in a final SNUR are subject to the TSCA section 13 import 
certification requirements, which are codified at 19 CFR 12.118 through 
12.127 and 127.28. Such persons must certify that they are in 
compliance with SNUR requirements. The EPA policy in support of the 
import certification appears at 40 CFR part 707.

III. Substances Subject to This Rule

    EPA is establishing significant new use and recordkeeping 
requirements for the following chemical substances under 40 CFR part 
721, subpart E. In this unit, EPA provides a brief description for each 
substance, including its PMN number, chemical name (generic name if the 
specific name is claimed as CBI), CAS number (if assigned and and the 
specific chemical identity is not claimed as CBI), basis for the action 
taken by EPA in the TSCA section 5(e) consent order or as a non-

[[Page 3395]]

 section 5(e) SNUR for the substance (including the statutory citation 
and specific finding), toxicity concern, and the CFR citation assigned 
in the regulatory text section of this rule. The specific uses which 
are designated as significant new uses are cited in the regulatory text 
section of this document by reference to 40 CFR part 721, subpart B 
where the significant new uses are described in detail. 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. of this preamble.
    Where the underlying TSCA section 5(e) order prohibits the PMN 
submitter from exceeding a specified production limit without 
performing specific tests to determine the health or environmental 
effects of a substance, the tests are described in this unit. As 
explained further in Unit VI. of this preamble, the SNUR for such 
substances contains the same production limit, and exceeding the 
production limit is defined as a significant new use. Persons who 
intend to exceed the production limit must notify the Agency by 
submitting a significant new use notice (SNUN) at least 90 days in 
advance. In addition, this unit describes tests that are recommended by 
EPA to provide sufficient information to evaluate the substance, but 
for which no production limit has been established in the TSCA section 
5(e) order. Descriptions of recommended tests are provided for 
informational purposes.
    Data on potential exposures or releases of the substances, testing 
other than that specified in the TSCA section 5(e) order for the 
substances, or studies on analogous substances, which may demonstrate 
that the significant new uses being reported do not present an 
unreasonable risk, may be included with significant new use 
notification. Persons submitting a SNUN must comply with the same 
notice requirements and EPA regulatory procedures as submitters of 
PMNs, as stated in 40 CFR 721.1(c), including submission of test data 
on health and environmental effects as described in 40 CFR 720.50.
    EPA is not publishing SNURs for PMNs P-95-266, 95-615/616, P-95-
941, P-95-973, P-95-1046, P-95-1115, P-95-1827, P-95-1854, P-95-2075, 
P-96-262, P-96-291, P-96-317, P-96-576 through P-96-581, P-96-726 
through P-96-744, P-96-803/804, P-96-1277/78, P-96-1482/1483, P-96-
1708, P-96-1509/1519, P-96-1548 through P-96-1551, P-97-205 through P-
97-208, and P-97-276/277 which are subject to a final TSCA section 5(e) 
consent order. The TSCA section 5(e) consent orders for these 
substances are derived from an exposure finding based solely on 
substantial production volume and significant or substantial human 
exposure and/or release to the environment of substantial quantities. 
For these cases there were limited or no toxicity data available for 
the PMN substances. In such cases, EPA regulates the new chemical 
substances under TSCA section 5(e) by requiring certain toxicity tests. 
For instance, chemical substances with potentially substantial releases 
to surface waters would be subject to toxicity testing of aquatic 
organisms and chemicals with potentially substantial human exposures 
would be subject to health effects testing for mutagenicity, acute 
effects, and subchronic effects. However, for these substances, the 
short-term toxicity testing required by the TSCA section 5(e) order is 
usually completed within 1 to 2 years of notice of commencement (NOC). 
EPA's experience with exposure-based SNURs requiring short-term testing 
is that the SNUR is often revoked within 1 to 2 years when the test 
results are received. Rather than issue and revoke SNURs in such a 
short span of time, EPA will defer publication of exposure-based SNURs 
until either a NOC or data demonstrating risk are received unless the 
toxicity testing required is long-term. EPA is issuing this explanation 
and notification as required in 40 CFR 721.160(a)(2) as it has 
determined that SNURs are not needed at this time for these substances 
which are subject to a final TSCA section 5(e) consent order under 
TSCA.

PMN Number P-87-323

Chemical name: (generic) Poly(oxy-1,2-ethanediyl), alpha substituted-
omega-hydroxy-, C<INF>16-20</INF> alkyl ethers.
CAS number: Not available.
Basis for action: The PMN substance will be used as an intermediate. 
Based on submitted fish, daphnia, and algae tests on the PMN substance, 
EPA expects toxicity to aquatic organisms at surface water 
concentrations as low as 20 parts per billion (ppb). EPA determined 
that use of the substance as described in the PMN did not present an 
unreasonable risk because the substance did not exceed a concentration 
of 20 ppb when released to surface waters. EPA has determined that 
other uses may result in releases to surface waters above 20 ppb. Based 
on this information the PMN substance meets the concern criteria at 
Sec. 721.170(b)(4)(i).
Recommended testing: EPA has determined that a chronic 60-day fish 
early life stage toxicity test in rainbow trout (40 CFR 797.1600 or 
OPPTS 850.1400 test guideline (public draft; 61 FR 16486, April 15, 
1996) (FRL-5363-1)) and a 21-day daphnid chronic toxicity test (40 CFR 
797.1330 or OPPTS 850.1300 test guideline (public draft; 61 FR 16486, 
April 15, 1996) (FRL-5363-1)) would help characterize the environmental 
effects of the PMN substance.
CFR citation: 40 CFR 721.3488.

PMN Number P-88-1108

Chemical name: (generic) Alcohols, C<INF>6-12</INF>, ethoxylated, 
reaction product with maleic anhydride.
CAS number: Not available.
Basis for action: The PMN substance will be used as a plastics 
additive. Based on analogy to anionic surfactants, EPA is concerned 
that toxicity to aquatic organisms may occur at a concentration as low 
as 300 ppb of the PMN substance in surface waters. EPA determined that 
use of the substance as described in the PMN did not present an 
unreasonable risk because the substance would not be released to 
surface waters in significant quantities. EPA has determined that other 
uses of the substance may result in releases to surface waters which 
exceed the concern concentration. Based on this information the PMN 
substance meets the concern criteria at Sec. 721.170(b)(4)(ii).
Recommended testing: EPA has determined that a fish acute toxicity 
study (40 CFR 797.1400 or OPPTS 850.1075 test guideline (public draft; 
61 FR 16486, April 15, 1996) (FRL-5363-1)), a daphnid acute toxicity 
study (40 CFR 797.1300 or OPPTS 850.1010 test guideline (public draft; 
61 FR 16486, April 15, 1996) (FRL-5363-1)), and an algal acute toxicity 
study (40 CFR 797.1050 or OPPTS 850.5400 test guideline (public draft; 
61 FR 16486, April 15, 1996) (FRL-5363-1)) would help characterize the 
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.524.

PMN Number P-90-581

Chemical name: (generic) Brominated phthalate ester.
CAS number: Not available.
Effective date of section 5(e) consent order: March 21, 1996.
Basis for section 5(e) consent order: 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 
health and the environment.
Toxicity concern: Similar chemicals have been shown to form 
dibenzodioxins and dibenzofurans when incinerated under combustion 
conditions of municipal incinerators.

[[Page 3396]]

Recommended testing: An incineration simulation study is required to 
help characterize the potential for the formation of dibenzodioxins or 
dibenzofurans when plastics or resins containing the PMN substance are 
incinerated. The PMN submitter has agreed not to exceed the production 
volume limit without performing this study.
CFR citation: 40 CFR 721.3085.

PMN Numbers P-91-1131 and P-90-564

Chemical name: (generic) Imidazolethione.
CAS number: Not available.
Effective date of section 5(e) consent order: October 25, 1995.
Basis for section 5(e) consent order: 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.
Toxicity concern: Based on the submitted 90-day subchronic study, the 
PMN substance causes thyroid and other systemic effects in test 
animals. Based on the submitted developmental toxicity study, the PMN 
substance causes developmental toxicity in test animals. Based on 
analogy to structurally similar substances the PMN substance may cause 
thyroid cancer.
Recommended testing: A 2-year, two-species oral bioassay in rats (40 
CFR 799.9420) (62 FR 43838, August 15, 1997) (FRL-5719-5) is 
recommended to help characterize the human health effects of the PMN 
substance.
CFR citation: 40 CFR 721.4469.

PMN Number P-92-314

Chemical name: (generic) Aryloxyarene.
CAS number: Not available.
Effective date of section 5(e) consent order: March 11, 1996.
Basis for section 5(e) consent order: 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 the 
environment.
Toxicity concern: Based on test data on this substance, there is 
concern for toxicity to aquatic organisms, particularly effects on 
daphnid reproduction, at concentrations as low as 1 ppb in surface 
waters.
Recommended testing: A 28-day chironomid sediment toxicity study (OPPTS 
850.1790 test guideline (public draft; 61 FR 16486, April 15, 1996)) 
(FRL-5363-1) is recommended to help characterize the toxicity of the 
PMN substance to benthic organisms.
CFR citation: 40 CFR 721.977.

PMN Numbers P-93-204 and P-94-1870 through P-94-1874

Chemical name: (generic) Phenyl substituted triazolinones.
CAS numbers: Not available.
Effective date of section 5(e) consent order: July 23, 1996.
Basis for section 5(e) consent order: The order was issued under 
section 5 (e)(1)(A)(i) and (e)(1)(A)(ii)(I) of TSCA based on a finding 
that these substances may present an unreasonable risk of injury to 
human health and the environment.
Toxicity concern: Data on several of the PMN substances and a chemical 
similar to P-94-1870 have shown developmental and reproductive effects, 
blood and liver effects, and neurotoxicity in test animals.
Recommended testing: An oral developmental toxicity study in rats (40 
CFR 799.9370) (62 FR 43832, August 15, 1997) (FRL-5719-5) and a 90-day 
subchronic oral study in rats (40 CFR 798.2650 or OPPTS 870.3100 test 
guideline (public draft; 61 FR 31522, June 20, 1996) (FRL-5367-7)) 
would help characterize the human health effects. A semi-continuous 
activated sludge (SCAS) study (OPPTS 835.3210 test guideline (public 
draft; 61 FR 16486, April 15, 1996)) (FRL-5363-1), a ready 
biodegradability study (OPPTS 835.3110 test guideline (public draft; 61 
FR 16486, April 15, 1996)) (FRL-5363-1), and a soil sediment adsorption 
isotherm (40 CFR 796.2750 or OPPTS 835.1220 test guideline (public 
draft; 61 FR 16486, April 15, 1996) (FRL-5363-1) would help 
characterize the environmental effects of the substance.
CFR citation: 40 CFR 721.9825.

PMN Number P-93-568

Chemical name: (generic) Polysubstituted piperidine.
CAS number: Not available.
Basis for action: The PMN substance will be used as an intermediate. 
Based on submitted test data, EPA is concerned that toxicity to aquatic 
organisms may occur at a concentration as low as 30 ppb of the PMN 
substance in surface waters. EPA determined that use of the substance 
as described in the PMN did not present an unreasonable risk because 
the substance would not be released to surface waters above a level of 
30 ppb. EPA has determined that other uses of the substance may result 
in releases to surface waters which exceed the concern concentration. 
Based on this information the PMN substance meets the concern criteria 
at Sec. 721.170(b)(4)(i).
Recommended testing: EPA has determined that a chronic 60-day fish 
early life stage toxicity test in rainbow trout (40 CFR 797.1600 or 
OPPTS 850.1400 test guideline (public draft; 61 FR 16486, April 15, 
1996) (FRL-5363-1)) and a 21-day daphnid chronic toxicity test (40 CFR 
797.1330 or OPPTS 850.1300 test guideline (public draft; 61 FR 16486, 
April 15, 1996) (FRL-5363-1)) would help characterize the environmental 
effects of the PMN substance.
CFR citation: 40 CFR 721.6165.

PMN Number P-93-761

Chemical name: 2-Pyrrolidinone, 1,1'-(2-methyl-1,5-pentanediyl)bis-.
CAS number: 146453-62-5.
Effective date of section 5(e) consent order: September 6, 1995.
Basis for section 5(e) consent order: 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.
Toxicity concern: Test data on the PMN substance and similar chemicals 
have shown that these types of chemicals cause systemic toxicity and 
neurotoxicity in test animals.
Recommended testing: A 90-day oral subchronic study in rats (40 CFR 
798.2650 or OPPTS 870.3100 test guideline (public draft; 61 FR 31522, 
June 20, 1996) (FRL-5367-7)) with additional neurotoxicity endpoints 
following NTIS-PB91-154617 (functional observation battery, 
neurohistopathology and motor activity) would help to characterize the 
systemic and neurotoxicity effects. The PMN submitter has agreed not to 
exceed the production volume limit without performing this test.
CFR citation: 40 CFR 721.9005.

PMN Number P-93-1369

Chemical name: (generic) N,N'-di(alkyl heteromonocycle)amino 
chlorotriazine.
CAS number: Not available.
Effective date of section 5(e) consent order: June 13, 1995.
Basis for section 5(e) consent order: 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 
health and the environment.
Toxicity concern: Similar chemicals have been shown to cause systemic 
toxicity, developmental toxicity, and cancer in test animals. In 
addition, similar chemicals have been shown to be toxic to aquatic 
organisms.
Recommended testing: EPA has determined that a 90-day subchronic 
toxicity test in rats via gavage (40 CFR 798.2650 or OPPTS 870.3100 
test guideline (public draft; 61 FR 31522,

[[Page 3397]]

June 20, 1996) (FRL-5367-7)), a two-species developmental study (rodent 
and non-rodent) (40 CFR 799.9370) (62 FR 43832, August 15, 1997) (FRL-
5719-5) and a 2-year, one-species bioassay (rats) (40 CFR 799.9420) (62 
FR 43838, August 15, 1997) (FRL-5719-5) would help characterize the 
human health effects of the PMN substance. The 90-day subchronic 
toxicity test should include special emphasis on hematology; weight of 
the spleen and thymus; cellularity of the bone marrow, thymus, and 
spleen; and histopathology of the liver, kidney, heart, and all 
endocrine glands for which weight changes are observed. In addition 
natural killer cell activity should be evaluated on the same population 
of test animals, and IgM antibody plaque-forming cells should be 
enumerated in two satellite groups of animals (10 in the high-dose 
group and 10 in the control group). EPA has determined that a fish 
acute toxicity study (40 CFR 797.1400 or OPPTS 850.1075 test guideline 
(public draft; 61 FR 16486, April 15, 1996) (FRL-5363-1)), a daphnid 
acute toxicity study (40 CFR 797.1300 or OPPTS 850.1010 (public draft; 
61 FR 16486, April 15, 1996) (FRL-5363-1)), and an algal acute toxicity 
study (40 CFR 797.1050 or OPPTS 850.5400 test guideline (public draft; 
61 FR 16486, April 15, 1996) (FRL-5363-1)) would help characterize the 
environmental effects of the PMN substance. The consent order contains 
two production volume limits. The PMN submitter has agreed not to 
exceed the first production volume limit without performing the 90-day 
subchronic toxicity test. The PMN submitter has also agreed not to 
exceed the second higher production volume limit without performing the 
two-species developmental study and the 2-year, one-species bioassay if 
the results of the 90-day test indicate biological activity at low 
levels (i.e., activity levels comparable to those for triazines).
CFR citation: 40 CFR 721.2094.

PMN Number P-93-1631

Chemical name: (generic) Substituted naphtholazo-substituted 
naphthalenyl-substituted azonaphthol chromium complex.
CAS number: Not available.
Basis for action: The PMN substance will be used as a dye. Based on 
analogy to structurally similar substances, EPA is concerned that 
cancer will occur in exposed workers. Based on submitted test data, EPA 
is concerned that toxicity to aquatic organisms may occur at a 
concentration as low as 1 ppb of the PMN substance in surface waters. 
EPA determined that use of the substance did not present an 
unreasonable risk because significant worker or environmental exposure 
is not expected because the substance was used as a liquid and was not 
manufactured domestically. EPA has determined that domestic manufacture 
of the substance and use as a solid may result in significant worker or 
environmental exposure. Based on this information the PMN substance

PMN Numbers P-95-1103, P-95-1104, and P-96-1235

Chemical name: (generic) Substituted resorcinols.
CAS number: Not available.
Basis for action: The PMN substances will be used as components of a 
material for integrated circuit fabrication. Based on submitted 
toxicity data and analogy to phenols, EPA is concerned that toxicity to 
aquatic organisms may occur at a concentration as low as 9 ppb of P-95-
1103/P-95-1104 and 1 ppb of P-96-1235 in surface waters. EPA determined 
that use of the substances as described in the PMNs did not present an 
unreasonable risk because the substances would not be released to 
surface waters in significant quantities. EPA has determined that other 
uses of the substances may result in releases to surface waters which 
exceed the concern concentration. Based on this information the PMN 
substances meet the concern criteria at Sec. 721.170(b)(4)(i) and 
(b)(4)(ii).
Recommended testing: EPA has determined that a chronic 60-day fish 
early life stage toxicity test in rainbow trout (40 CFR 797.1600 or 
OPPTS 850.1400 test guideline (public draft; 61 FR 16486, April 15,

has determined that halogenated dioxins and furans are probable human 
carcinogens and may cause toxic effects in aquatic and terrestrial 
organisms.
Recommended testing: The consent order contains two production volume 
limits. The PMN submitter has agreed not to exceed the first production 
volume limit without performing an incineration simulation study 
(guidelines available from EPA) to help characterize the potential for 
the formation of dibenzodioxins or dibenzofurans when plastics or 
resins containing the substance are incinerated, and a porous pot test 
(OPPTS 835.3220 test guideline (public draft; 61 FR 16486, April 15, 
1996) (FRL-5363-1) to determine the extent of environmental degradation 
of the substance. The PMN submitter has also agreed not to exceed the 
second, higher production volume limit without performing a shake flask 
die-away test (OPPTS 835.3170 test guideline (public draft; 61 FR

IV. Objectives and Rationale of the Rule

    During review of the PMNs submitted for the chemical substances 
that are subject to this SNUR, EPA concluded that for 25 of the 163 
substances, regulation was warranted under section 5(e) of TSCA, 
pending the development of information sufficient to make reasoned 
evaluations of the health or environmental effects of the substances. 
The basis for such findings is outlined in Unit III. of this preamble. 
Based on these findings, TSCA section 5(e) consent orders requiring the 
use of appropriate controls were negotiated with the PMN submitters; 
the SNUR provisions for these substances designated herein are 
consistent with the provisions of the TSCA section 5(e) orders.
    In the other 138 cases for which the proposed uses are not 
regulated under a TSCA section 5(e) order, EPA determined that one or 
more of the criteria of concern established at 40 CFR 721.170 were met.
    EPA is issuing this SNUR for specific chemical substances which 
have undergone premanufacture review to ensure that:
    (1) EPA will receive notice of any company's intent to manufacture,

[[Page 3417]]

import, or process a listed chemical substance for a significant new 
use before that activity begins.
    (2) EPA will have an opportunity to review and evaluate data 
submitted in a SNUR notice before the notice submitter begins 
manufacturing, importing, or processing a listed chemical substance for 
a significant new use.
    (3) When necessary to prevent unreasonable risks EPA will be able 
to regulate prospective manufacturers, importers, or processors of a 
listed chemical substance before a significant new use of that 
substance occurs.
    (4) All manufacturers, importers, and processors of the same 
chemical substance which is subject to a TSCA section 5(e) order are 
subject to similar requirements. Issuance of a SNUR for a chemical 
substance does not signify that the 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 direct final rules, as described in 
40 CFR 721.160(c)(3) and 721.170(d)(4). In accordance with 40 CFR 
721.160(c)(3)(ii), this rule will be effective March 23, 1998, unless 
EPA receives a written notice by February 23, 1998 that someone wishes 
to make adverse or critical comments on EPA's action. If EPA receives 
such a notice, EPA will publish a notice to withdraw the direct final 
SNUR for the specific substance to which the adverse or critical 
comments apply. EPA will then propose a SNUR for the specific substance 
providing a 30-day comment period.
    This action establishes SNURs for a number of chemical substances. 
Any person who submits a notice of intent to submit adverse or critical 
comments must identify the substance and the new use to which it 
applies. EPA will not withdraw a SNUR for a substance not identified in 
a notice.

VI. Test Data and Other Information

    EPA recognizes that section 5 of TSCA 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. 
In cases where a TSCA section 5(e) order requires or recommends certain 
testing, Unit III. of this preamble lists those recommended tests.
    However, EPA has established production limits in the TSCA section 
5(e) orders for several of the substances regulated under this rule, in 
view of the lack of data on the potential health and environmental 
risks that may be posed by the significant new uses or increased 
exposure to the substances. These production limits cannot be exceeded 
unless the PMN submitter first submits the results of toxicity tests 
that would permit a reasoned evaluation of the potential risks posed by 
these substances. Under recent consent orders, each PMN submitter is 
required to submit each study at least 14 weeks (earlier orders 
required submissions at least 12 weeks) before reaching the specified 
production limit. Listings of the tests specified in the TSCA section 
5(e) orders are included in Unit III. of this preamble. The SNURs 
contain the same production volume limits as the consent orders. 
Exceeding these production limits is defined as a significant new use.
    The recommended studies may not be the only means of addressing the 
potential risks of the substance. 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:
    (1) Human exposure and environmental release that may result from 
the significant new use of the chemical substances.
    (2) Potential benefits of the substances.
    (3) Information on risks posed by the substances compared to risks 
posed by potential substitutes.

VII. Procedural Determinations

    EPA is establishing through this rule some 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 substance subject to a SNUR is CBI. 
This procedure is cross-referenced in each of these SNURs.
    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 incorporated from Sec. 721.1725(b)(1), a manufacturer or 
importer must show that it has a bona fide intent to manufacture or 
import the substance and must identify the specific use for which it 
intends to manufacture or import the substance. If EPA concludes that 
the person has shown a bona fide intent to manufacture or import the 
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 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 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 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 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. TSCA section 5(e) orders have 
been issued for 24 substances and notice submitters are prohibited by 
the TSCA section 5(e) orders from undertaking activities which EPA is 
designating as significant new uses. In cases where EPA has not 
received a NOC and the substance has not been added to the TSCA 
Inventory, no other person may commence such activities without first 
submitting a PMN. For substances for which an NOC has not been 
submitted

[[Page 3418]]

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 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, 123 of the 163 substances 
contained in this rule have CBI chemical identities, and since EPA has 
received a limited number of post-PMN bona fide submissions, the Agency 
believes that it is highly unlikely that any of the significant new 
uses described in the following regulatory text 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) is best 
served by designating a use as a significant new use as of the date of 
publication rather than as of the effective date of the rule. Thus, 
persons who begin commercial manufacture, import, or processing of the 
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. If persons who begin commercial manufacture, 
import, or processing of the substance between publication and the 
effective date of the SNUR do not meet the conditions of advance 
compliance, they must cease that activity before the effective date 
of the 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.

IX. Economic Analysis

    EPA has evaluated the potential costs of establishing significant 
new use notice requirements for potential manufacturers, importers, and 
processors of the chemical substance subject to this rule. EPA's 
complete economic analysis is available in the public record for this 
rule (OPPTS-50628).

XI. Regulatory Assessment Requirements

    Under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993), this action is not a 
``significant regulatory action'' subject to review by the Office of 
Management and Budget (OMB). In addition, this action does not impose 
any enforceable duty or contain any unfunded mandate as described in 
the Unfunded Mandates Reform Act (UMRA) of 1995 (Pub. L. 104-4), or 
require prior consultation with State officials as also specified in 
Executive Order 12875, entitled ``Enhancing the Intergovernmental 
Partnership'' (58 FR 58093, October 28, 1993). Nor does it involve 
special considerations of environmental justice related issues as 
required by Executive Order 12898, entitled ``Federal Actions to 
Address Environmental Justice in Minority Populations and Low-Income 
Populations'' (59 FR 7629, February 16, 1994), or additional OMB review 
in accordance with Executive Order 13045, entitled ``Protection of 
Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997).
    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, after initial display in the preamble of the final rules, 
are listed in 40 CFR part 9. 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 significant new use notice 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 
significant new use notice.
    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, 
OPPE Regulatory Information Division, U.S. Environmental Protection 
Agency (Mail Code 2137), 401 M Street, S.W., Washington, D.C. 20460, 
with a copy to the Office of Information and Regulatory Affairs, Office 
of Management and Budget, 725 17th St., N.W., Washington, DC 20503, 
marked ``Attention: Desk Officer for EPA.'' Please remember to include 
the OMB control number in any correspondence, but do not submit any 
completed forms to these addresses.
    In addition, pursuant to section 605(b) of the Regulatory 
Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency has previously 
certified, as a generic matter, that the promulgation of a SNUR does 
not have a significant adverse economic impact on a substantial number 
of small entities. The Agency's generic certification for promulgation 
of new SNURs appears on June 2, 1997 (62 FR 29684) (FRL-5597-1), and 
was provided to the Chief Counsel for Advocacy of the Small Business 
Administration.

XII. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, the Agency has submitted a 
report containing this rule and other required

[[Page 3419]]

information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the General Accounting Office prior to 
publication of this rule in today's Federal Register. This is not a 
major rule as defined by 5 U.S.C. 804(2).

reporting. (1) The chemical substance identified as phenol, 4-(1,1-
dimethylethyl)-, homopolymer (PMN P-95-243; CAS No. 30813-81-1) is 
subject to reporting under this section for the significant new uses 
described in paragraph (a)(3) of this section.
    (2) High moleculation weight exemption. A batch of the chemical 
substance may be exempt from the provisions of this rule if the average 
number molecular weight of the substance is greater than 1,000 and the 
low molecular weight species below 1,000 and 500 are less than 25 
percent and 10 percent, respectively. To be eligible for this 
exemption, the batch must be individually measured.
    (3) The significant new uses are:
    (i) Hazard communication program. Requirements as specified in 
Sec. 721.72 (a), (b), (d), (f), (g)(3)(i), (g)(4)(i), and (g)(5). The 
label and material safety data sheet (MSDS) as required by this 
paragraph shall also include the following statement: This substance is 
toxic to aquatic invertebrate.
    (ii) Industrial, commercial, and consumer activites. Requirements 
as specified in Sec. 721.80(q).
    (iii) Release to water. Requirements as specified in Sec. 721.90 
(a)(4) and (b)(4) (N = 9). When calculating the surface water 
concentrations according to the instructions in Sec. 721.91, the 
statement that the amount of the substance that will be released will 
be calculated before the substance enters control technology does not 
apply. Instead, if the waste stream containing the substance will be 
treated using primary and secondary wastewater treatment with control 
of suspended solids, before release, then the amount of the substance 
reasonably likely to be removed from the waste stream by such treatment 
may be subtracted in calculating the number of kilograms released. No 
more than 95 percent removal efficiency may be attributed to such 
treatment. These requirements do not apply to the sites specifically 
exempted in the TSCA section 5(e) consent order for this substance.
    (b) Specific requirements. The provisions of subpart A of this part 
apply to this section except as modified by this paragraph.
    (1) Recordkeeping. Recordkeeping requirements as specified in 
Sec. 721.125 (a), (b), (c), (f), (g), (h), (i), and (k) are applicable 
to manufacturers, importers, and processors of this substance.
    (2) Limitations or revocation of certain notification requirements. 
The provisions of Sec. 721.185 apply to this section.
    (3) Determining whether a specific use is subject to this section. 
The provisions of Sec. 721.1725(b)(1) apply to this section.
    8. By adding new Sec. 721.539 to subpart E to read as follows:


Sec. 721.539   Poly(oxy-1,2-ethanediyl), <greek-a>-sulfo-<greek-oh>-[1-
[(4-nonylphenoxy)methyl]-2-(2-propenyloxy)ethoxy]-, branched, ammonium 
salts.

reporting. (1) The chemical substance identified as Poly(oxy-1,2-
ethanediyl), <greek-a>-sulfo-<greek-oh>-[1-[(4-nonylphenoxy)methyl]-2-
(2-propenyloxy)ethoxy]-, branched, ammonium salts (PMN P-96-1240; CAS 
No. 184719-88-8) is subject to reporting under this section for the
