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 certain 
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 October 30, 1995. This rule 
shall be 

[[Page 45073]]
promulgated for purposes of judicial review at 1 p.m. Eastern Standard 
Time on September 13, 1995. If EPA receives notice before September 29, 
1995 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-50622 and 
the names of the chemical substances 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, Rm. E-G99, 401 M St., SW., Washington, DC 20460. All 
comments which are claimed confidential must be clearly marked as such. 
Three additional sanitized copies of any comments containing 
confidential business information (CBI) must also be submitted. 
Nonconfidential versions of comments on this rule will be placed in the 
rulemaking record and will be available for public inspection.
    Comments and data may also be submitted electronically by sending 
electronic mail (e-mail) to: [e-mail]. Electronic comments 
must be submitted as an ASCII file avoiding the use of special 
characters and any form of encryption. Comments and data will also be 
accepted on disks in WordPerfect in 5.1 file format or ASCII file 
format. All comments and data in electronic form must be identified by 
the docket number OPPTS-50622. No CBI should be submitted through e-
mail. Electronic comments on this final rule may be filed online at 
many Federal Depository Libraries. Additional information on electronic 
submissions can be found in Unit X. of this document.

e-mail: [e-mail].

SUPPLEMENTARY INFORMATION: 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 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 at 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 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 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 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 the 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), basis for 
the action taken by EPA in the section 5(e) consent order or as a non-
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 of this rule. The specific uses which are 
designated as significant new uses are cited in the regulatory text 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 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 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 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 

[[Page 45074]]
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 P-93-1231, P-93-1315, P-94-212, P-
94-343/344, P-94-506/507/508/509, P-94-615/616, P-94-697 through P-94-
895, P-94-919, P-94-1080, P-94-1484, P-94-1561/1562/1563/1564, P-94-
1634/1635/1636/1637/1638/1639, P-94-1705, and P-94-1771, which are 
subject to a final TSCA 5(e) consent order. The 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 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 5(e) order is usually 
completed within 1 to 2 years of notice of commencement. 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 Notice of Commencement (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 5(e) consent 
order under TSCA.
    On March 29, 1994, EPA received a SNUN, P-94-1218, for 1,1,1-
trifluoroethane which is subject to a SNUR at 40 CFR 721.4390. The 
submitter was notifying EPA that it intended to exceed the production 
volume limit for the substance. EPA allowed the 90-day review period to 
expire without taking any action. EPA is in the process of revoking the 
SNUR based on toxicity testing received for the substance. EPA is 
issuing this explanation and notification as required in section 5(g) 
of TSCA as it has not initiated any action to prohibit or limit 
manufacture, process, distribute in commerce, use, or dispose of 1,1,1-
trifluoroethane with respect to which notification or data was required 
by the SNUR.
    The designation L-91-87 for the substance with the generic name 
``substituted phenol'' denotes a low-volume exemption which is an 
exemption to premanufacture requirements of section 5(a)(1)(A) of TSCA. 
The terms and requirements are described in Sec. 723.50.

PMN Number P-85-619

Chemical name: (generic) Tetrasubstituted aminocarboxylic acid.
CAS number: Not available.
Effective date of section 5(e) consent order: August 4, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (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: Test data on substances similar in structure to the 
PMN substance have been shown to cause carcinogenicity and mutagenicity 
in test animals and toxicity to aquatic organisms.
Recommended testing: EPA has determined that the results of a 2-year 
two-species rodent bioassay (40 CFR 798.3300) would help characterize 
the carcinogenic effects of the PMN substance. A 96-hour bioassay in 
algae (40 CFR 797.1050) and a 96-hour LC50 study in fish (40 CFR 
797.1400) would help to characterize the environmental effects of the 
substance.
CFR citation: 40 CFR 721.2089.

PMN Number P-85-941

Chemical name: (generic) Substituted alkylamine salt.
CAS number: Not available.
Basis of action: The PMN substance will be used as described in the 
PMN. Based on test data on the substance, EPA is concerned that 
toxicity to aquatic organisms may occur at concentrations as low as 70 
ppb (parts per billion) 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 concentration of 70 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) and a 
21-day chronic daphnid toxicity test would help characterize the 
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.562.

PMN Number P-86-1491

Chemical name: (generic) 3-Hydroxy-1,1-dimethylbutyl derivative.
CAS number: Not available.
Effective date of section 5(e) consent order: January 21, 1987.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (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 substances similar in structure to the 
PMN substance have been shown to cause carcinogenicity in test animals.
Recommended testing: EPA has determined that the results of a 2-year 
two-species rodent bioassay (40 CFR 798.3300) would help characterize 
the carcinogenic effects of the PMN substance
CFR citation: 40 CFR 721.4466.

PMN Number P-87-1036

Chemical name: (generic) Substituted 1,6-dihydroxynaphthalene.
CAS number: Not available.
Effective date of section 5(e) consent order: October 30, 1987.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i), (ii)(I), and (ii)(II) of TSCA based on a finding 
that this substance may present an unreasonable risk of injury to human 
health and that this substance is expected to be produced in 
substantial quantities and that there may be significant or substantial 
human exposure.
Toxicity concern: Test data on substances similar in structure to the 
PMN substance have been shown to cause carcinogenicity and reproductive 
effects in test animals.
Recommended testing: EPA has determined that the results of a 90-day 
subchronic dermal study (40 CFR 798.2650) and a 2-year two-species 
rodent bioassay (40 CFR 798.3300) would help characterize the health 
effects of the PMN substance. The PMN submitter has agreed not to 
exceed the production volume limit without performing the 90-day 
subchronic study.
CFR citation: 40 CFR 721.5192.

PMN Numbers P-88-998/999

Chemical name: (generic) Fluorene-containing diaromatic amines.
CAS number: Not available. 

[[Page 45075]]

Basis of action: The PMN substances will be used as matrix resins. 
Based on data on the PMN substances, EPA is concerned that toxicity to 
aquatic organisms may occur at concentrations as low as 1 ppb of the 
PMN substances in surface waters. EPA determined that use of the 
substances as described in the PMN did not present an unreasonable risk 
because the substances did not exceed a concentration of 1 ppb when 
released to surface waters. EPA has determined that other uses may 
result in releases to surface waters above 1 ppb. Based on this 
information, the PMN substances meet 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) and a 
21-day chronic daphnid toxicity test would help characterize the 
environmental effects of the PMN substances.
CFR citation: 40 CFR 721.3760.

PMN Number P-91-818

Chemical name: (generic) Alkyldi(alkyl oxyhydroxypropyl) derivative, 
phosphoric acid esters, potassium salts.
CAS number: Not available.
Basis of action: The PMN substance will be used as a mining chemical. 
Based on data on the PMN substance, EPA is concerned that toxicity to 
aquatic organisms may occur at concentrations 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 did not exceed a concentration of 30 ppb when 
released to surface waters. EPA has determined domestic manufacture or 
consumer use may result in releases to surface waters above 30 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) and a 
21-day chronic daphnid toxicity test would help characterize the 
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.6110.

PMN Number P-93-633

Chemical name: (generic) Aliphatic ester.
CAS number: Not available.
Effective date of section 5(e) consent order: September 28, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (ii)(I) of TSCA based on a finding that this 
substance may present an unreasonable risk of injury to health.
Toxicity concern: Similar chemicals have been shown to cause liver and 
developmental toxicity in test animals.
Recommended testing: The Agency has determined that the results of a 
90-day subchronic toxicity (40 CFR 798.2650) and developmental toxicity 
(oral route) (40 CFR 798.4900) studies would help characterize liver 
and developmental effects.
CFR citation: 40 CFR 721.2815.

PMN Number P-93-955

Chemical name: (generic) Formaldehyde, polymer with substituted 
phenols, glycidyl ether.
CAS number: Not available.
Effective date of section 5(e) consent order: June 16, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (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: The PMN substance has been shown to cause systemic 
effects in test animals. Similar chemicals have been shown to cause 
systemic toxicity, reproductive toxicity, mutagenicity, and oncogencity 
in test animals. Similar chemicals have been shown to cause toxicity to 
aquatic organisms.
Recommended testing: A 90-day subchronic (oral) toxicity test with 
special attention to the testes will help to characterize the systemic 
and reproductive effects. The PMN submitter has agreed not to exceed 
the production volume limit without performing this test. A 2-year, 
two-species rodent (oral) bioassay study (40 CFR Sec. 798.3300) would 
be required to evaluate the potential oncogenic effects of the PMN 
substance. A 96-hour bioassay in algae (40 CFR 797.1050), a 48-hour 
LC50 test in daphnia (40 CFR 797.1300), and a 96-hour LC50 test in 
freshwater fish (40 CFR 797.1400) would be required to evaluate the 
environmental effects which may be caused by the PMN substance. The 
algal test should be conducted with static conditions and measured 
concentrations.
    The remaining tests should be conducted with flow-through 
conditions and measured concentrations. To evaluate worker exposure 
from the potential dusting of the PMN substance, simulation of shipping 
and handling conditions using the following 2-step set of tests from 
the current version of the American Society of Testing and Materials 
(ASTM) guidelines would be required. Drop tests for the PMN substance 
in their shipping containers should be conducted according to ASTM 
Method D959--Drop test for Filled Bags and ASTM Method D997--Drop Test 
for Loaded Cylindrical Containers. The PMN substance in the bags or 
containers in the studies above should be tested using ASTM Method 
D999--Vibration Testing of Shipping Containers.
    After the 2-step set of tests is complete, the particle size 
distribution of the PMN substance from the shipping containers should 
be measured using ASTM Method D 1921--Standard Test Methods for 
Particle Size (Sieve Analysis) of Plastic Materials, using wire-cloth 
sieves meeting the requirements of ASTM D11--Standard Specifications 
for Wire-Cloth Sieves for Testing Purposes.
CFR citation: 40 CFR 721.7046.

PMN Number P-93-987

Chemical name: (generic) Mixture of nitrated alkylated phenols.
CAS number: Not available.
Basis of action: The PMN substance will be used as a polymerization 
inhibitor. Based on test data on the substance, EPA is concerned that 
toxicity to aquatic organisms may occur at concentrations as low as 1 
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 concentration of 1 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) and a 
21-day chronic daphnid toxicity test would help characterize the 
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.5769.

PMN Number P-93-1649

Chemical name: (generic) Alkylated urea.
CAS number: Not available.
Effective date of section 5(e) consent order: August 25, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (ii)(I) of TSCA based on a finding that this 
substance may present an unreasonable risk of injury to human health.
Toxicity concern: Similar chemicals have been shown to cause 
neurotoxicity 

[[Page 45076]]
and developmental toxicity in test animals.
Recommended testing: A dermal developmental toxicity study (40 CFR 
798.4900) and a 90-day dermal subchronic study (40 CFR 798.2250 and 
NTIS: PB91-154617) would help characterize the potential adverse 
neurotoxic and developmental effects of this 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 dermal developmental toxicity study. The PMN submitter 
has also agreed not to exceed the second production volume limit 
without performing the 90-day dermal subchronic study.
CFR citation: 40 CFR 721.9892.

PMN Number P-94-24

Chemical name: Ethanaminium, N-ethyl-2-hydroxy-N,N-bis(2-hydroxyethyl)-
, diester with C12-18 fatty acids, ethyl sulfates (salts).
CAS number: Not available.
Effective date of section 5(e) consent order: April 24, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i), (ii)(I), and (ii)(II), of TSCA based on findings 
that this substance may present an unreasonable risk of injury to the 
environment, is expected to be produced in substantial quantities, and 
may reasonably be expected to enter the environment in substantial 
quantities.
Recommended testing: EPA has also determined that a modified SCAS test 
(semicontinuous activated sludge procedure), a soil sediment adsorption 
isotherm test (40 CFR 796.2750), a fish acute toxicity study modified 
with humic acid (40 CFR 797.1400), a fish acute toxicity study (40 CFR 
797.1400), a daphnid acute toxicity study (40 CFR 797.1300), and an 
algal acute toxicity study (40 CFR 797.1050) would help characterize 
possible environmental effects of the substance. The PMN submitter has 
agreed not to exceed the production volume limit without performing 
these tests.
CFR citation: 40 CFR 721.3152.

PMN Number P-94-47

Chemical name: (generic) Polyurethane polymer.
CAS number: Not available.
Effective date of section 5(e) consent order: August 3, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (ii)(I) of TSCA based on a finding that this 
substance may present an unreasonable risk of injury to human health.
Toxicity concern: Similar chemicals have been shown to cause 
respiratory and dermal sensitization in test animals.
Recommended testing: EPA has determined that a dermal sensitization 
study (40 CFR 798.4100), a pulmonary sensitization study (Karol method 
or equivalent), and a 90-day subchronic inhalation study (40 CFR 
798.2450) will help characterize the health effects of the PMN 
substance. The PMN submitter has agreed not to exceed the production 
volume limit without performing these studies.
CFR citation: 40 CFR 721.8090.

PMN Number P-94-1042

Chemical name: (generic) Methylenebis benzotriazolyl phenols.
CAS number: Not available.
Effective date of section 5(e) consent order: September 1, 1994.
Basis for section 5(e) consent order: The order was issued under 
section 5(e)(1)(A)(i) and (ii)(I) of TSCA based on a finding that this 
substance may present an unreasonable risk of injury to human health.
Toxicity concern: Similar chemicals have been shown to cause systemic 
and reproductive toxicity in test animals.
Recommended testing: A 90-day gavage study in rats (40 CFR 
Sec. 798.2650) to help characterize systemic and reproductive effects. 
The PMN submitter has agreed not to exceed the production volume limit 
without performing this test.
CFR citation: 40 CFR 721.5763.

PMN Number P-94-1453

Chemical name: (generic) Hydrochloro fluorocarbon.
Basis of action: The PMN substance will be used as an intermediate. 
Based on analogy to similar substances, the PMN substance may cause 
cancer and cardiac sensitization. EPA has determined that persons 
exposed to the PMN substance through inhalation may be at risk for 
these toxic effects. EPA determined that use of the substance as 
described in the PMN did not present an unreasonable risk because there 
were no significant worker exposures from use as an intermediate. EPA 
has determined that worker exposures from use other than an 
intermediate may result in significant exposures. 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 a cardiac sensitization 
study in dogs and a 2-year two-species oral bioassay (40 CFR 798.3300) 
will help to characterize the health effects of the PMN substance.
CFR citation: 40 CFR 721.4463.

PMN Number P-94-1487

Chemical name: (generic) Thiaalkanethiol.
CAS number: Not available.
Basis of action: The PMN substance will be used as an surfactant. Based 
on analogy to anionic surfactants, EPA is concerned that toxicity to 
aquatic organisms may occur at concentrations as low as 20 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. EPA has 
determined that domestic manufacture of the substance may result in 
releases to surface waters. Based on this information, the PMN 
substance meets the concern criteria at Sec. 721.170(b)(4)(ii).
Recommended testing: EPA has determined that an algal acute toxicity 
study (40 CFR 797.1050), a chronic 60-day fish early life stage 
toxicity test in rainbow trout (40 CFR 797.1600), a 21-day chronic 
daphnid toxicity test, a ready biodegradability test, and a modified 
SCAS test would help characterize the environmental effects of the PMN 
substance.
CFR citation: 40 CFR 721.9656.

PMN Numbers P-89-1125, L-91-87, P-92-41, P-92-511, P-94-1527, and P-94-
1755

Chemical name: (generic) Substituted phenol.
CAS number: Not available.
Basis of action: The PMN substance has been the subject of six 
different PMN notices. Based on test data on the PMN substance and by 
analogy to phenols, EPA is concerned that toxicity to aquatic organisms 
may occur at concentrations as low as 1 ppb of the PMN substance in 
surface waters. EPA determined that use of the substance as described 
in several of the PMNs did not present an unreasonable risk because the 
substance did not exceed a concentration of 1 ppb when released to 
surface waters. The only PMN where releases over 1 ppb were expected 
has been withdrawn. EPA has determined that other uses and increased 
production volume may result in releases to surface waters above 1 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 an algal acute toxicity 
study (40 CFR 797.1050), a chronic 60-day fish early life stage 
toxicity test in rainbow trout (40 CFR 797.1600), and a 21-day chronic 
daphnid toxicity test would help characterize the 

[[Page 45077]]
environmental effects of the PMN substance.
CFR citation: 40 CFR 721.5867.

PMN Number P-94-1631

Chemical name: (generic) Thiadiazole derivative.
CAS number: Not available.
Basis of action: The PMN substance will be used as a coloring agent. 
Based on analogy of the substance to neutral organic substances, EPA is 
concerned that toxicity to aquatic organisms may occur at 
concentrations as low as 90 ppb of the PMN substance in surface waters. 
Based on analogy of the substance to other thiadiazoles, EPA is 
concerned for developmental toxicity to exposed workers. 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 concentration of 90 ppb and significant worker 
exposure would not occur because the substance was used in an enclosed 
process, was not manufactured domestically, and was not used as a 
powder. EPA has determined that other uses of the substance may result 
in significant worker exposure and 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) and 
(b)(3)(ii).
Recommended testing: EPA has determined that a fish acute toxicity 
study (40 CFR 797.1400), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance. EPA 
has determined that a developmental toxicity study (40 CFR 708.4900) 
would help characterize the health effects of the PMN substance.
CFR citation: 40 CFR 721.9658.

PMN Number P-94-1810

Chemical name: (generic) Amine aldehyde condensate.
CAS number: Not available.
Basis of action: The PMN substance will be used as a fuel additive. 
Based on analogy to aliphatic amines, EPA is concerned that toxicity to 
aquatic organisms may occur at concentrations as low as 1 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. 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), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance.
CFR citation: 40 CFR 721.639.

PMN Number P-94-1864

Chemical name: (generic) Dialkylamido imidazoline.
CAS number: Not available.
Basis of action: The PMN substance will be used as a site-limited 
intermediate. Based on analogy to aliphatic amines, EPA is concerned 
that toxicity to aquatic organisms may occur at concentrations as low 
as 6 ppb of the PMN substance in surface waters. EPA determined that 
use of the substance as a site-limited intermediate did not present an 
unreasonable risk because the substance would not exceed the concern 
concentration when released to surface waters. 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), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance.
CFR citation: 40 CFR 721.4473.

PMN Number P-94-2166

Chemical name: Sodium perthiocarbonate.
CAS number: Not available.
Basis of action: The PMN substance will be used as an oil well 
additive. Based on test data on a structurally similar substance, EPA 
is concerned that toxicity to aquatic organisms may occur at 
concentrations as low as 20 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. 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), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance.
CFR citation: 40 CFR 721.9526.

PMN Number P-94-2177

Chemical name: (generic) Trisodium chloro[(trisubstituted 
heteromonocycleamino) propylamino] triazinylaminohydroxyazo 
naphthalenetrisulfonate.
CAS number: Not available.
Basis of action: The PMN substance will be used as a fiber-reactive 
dye. Based on toxicity data for the substance, EPA is concerned that 
toxicity to aquatic organisms may occur at concentrations as low as 100 
ppb of the PMN substance in surface waters. Based on toxicity data for 
the substance, EPA is concerned for neurological effects, kidney 
toxicity, and liver toxicity to exposed workers. 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 concentration of 100 ppb and significant worker 
exposure would not occur because the substance was not manufactured 
domestically. EPA has determined that domestic manufacture of the 
substance may result in releases to surface waters which exceed the 
concern concentration and significant worker exposure. Based on this 
information, the PMN substance meets the concern criteria at 
Sec. 721.170(b)(4)(i) and (b)(3)(i).
Recommended testing: EPA has determined that a chronic 60-day fish 
early life stage toxicity test in rainbow trout (40 CFR 797.1600) and a 
21-day chronic daphnid toxicity test would help characterize the 
environmental effects of the PMN substance and a 90-day subchronic oral 
study in rats (40 CFR 798.2650) would help characterize the health 
effects of the PMN substance.
CFR citation: 40 CFR 721.5282.

PMN Number P-94-2230

Chemical name: (generic) Polyglycerin mono(4-nonyl phenyl) ether.
CAS number: Not available.
Basis of action: The PMN substance will be employed in a contained use. 
Based on analogy to nonionic surfactants and alcohol ethoxylates, EPA 
is concerned that toxicity to aquatic organisms may occur at 
concentrations as low as 400 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 

[[Page 45078]]
released to surface waters. EPA has determined that other uses, 
increased production volume, and domestic manufacture 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), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance.
CFR citation: 40 CFR 721.3486.

PMN Number P-95-17

Chemical name: Benzene, 2-bromo-1,4-dimethoxy-.
CAS number: 25245-34-5.
Basis of action: The PMN substance will be used as an intermediate. 
Based on analogy to neutral organic compounds, EPA is concerned that 
toxicity to aquatic organisms may occur at concentrations as low as 200 
ppb of the PMN substance in surface waters. Based on analogy to 
halogenated aromatic compounds, EPA is concerned that the substance may 
cause liver and kidney toxicity to exposed workers. EPA determined that 
use of the substance as an intermediate did not present an unreasonable 
risk because the substance would not be released to surface waters and 
significant worker exposure would not occur. EPA has determined that 
other uses of the substance may result in releases to surface waters 
which exceed the concern concentration and significant worker exposure. 
Based on this information, the PMN substance meets the concern criteria 
at Sec. 721.170(b)(4)(ii) and (b)(3)(ii).
Recommended testing: EPA has determined that a fish acute toxicity 
study (40 CFR 797.1400), a daphnid acute toxicity study (40 CFR 
797.1300), and an algal acute toxicity study (40 CFR 797.1050) would 
help characterize the environmental effects of the PMN substance and a 
90-day subchronic oral study in rats (40 CFR 798.2650) would help 
characterize the health effects of the PMN substance.
CFR citation: 40 CFR 721.1193.

PMN Number P-95-85

Chemical name: (generic) Substituted naphthalenesulfonic acid, alkali 
salt.
CAS number: Not available.
Basis of action: The PMN substance will be used as a reactive textile 
dye. Based on analogy to similar substances, EPA is concerned that 
respiratory sensitization will occur in exposed workers. EPA determined 
that use of the substance did not present an unreasonable risk because 
significant worker exposure would not occur because the substance was 
not manufactured domestically. EPA has determined that domestic 
manufacture of the substance may result in significant worker exposure. 
Based on this information, the PMN substance meets the concern criteria 
at Sec. 721.170(b)(3)(ii).
Recommended testing: EPA has determined that a respiratory 
sensitization study (Sarlo, K. and Clark, E.D., A Tier Approach for 
Evaluating the Respiratory Allergenicity of Low Molecular Weight 
Chemicals, Fundamental and Applied Toxicology 18:107-114 (1992)) would 
help characterize the health effects of the PMN substance.
CFR citation: 40 CFR 721.5278.

PMN Number P-95-86

Chemical name: (generic) Benzenesulfonic acid, amino substituted 
phenylazo-.
CAS number: Not available.
Basis of action: The PMN substance will be used as a textile dye. Based 
on analogy of the azo reduction products to a similar substance, EPA is 
concerned that developmental, reproductive, and kidney toxicity will 
occur in exposed workers. EPA determined that use of the substance did 
not present an unreasonable risk because the substance would not be 
manufactured as a powder and significant worker exposure would not 
occur. EPA has determined that manufacture of the substance as a powder 
may result in significant worker exposure. Based on this information, 
the PMN substance meets the concern criteria at 
Sec. 721.170(b)(3)(iii).
Recommended testing: EPA has determined that a 90-day subchronic oral 
study in rats (40 CFR 798.2650), a two-generation reproduction study 
(40 CFR 798.4700), and a developmental toxicity study (40 CFR 708.4900) 
would help characterize the health effects of the PMN substance.
CFR citation: 40 CFR 721.1643.

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 9 of the 26 
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, 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 section 5(e) orders.
    In the other 17 cases for which the proposed uses are not regulated 
under a 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: EPA will receive 
notice of any company's intent to manufacture, import, or process a 
listed chemical substance for a significant new use before that 
activity begins; 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; 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; and all manufacturers, importers, and 
processors of the same chemical substance which is subject to a 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 [insert date 60 days 
after date of publication in the Federal Register], unless EPA receives 
a written notice by [insert date 30 days after date of publication in 
the Federal Register] 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 

[[Page 45079]]
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 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 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 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 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. 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. Section 5(e) orders have been 
issued for nine substances and notice submitters are prohibited by the 
section 5(e) orders from undertaking activities which EPA is 
designating as significant new uses. In cases where EPA has not 
received a Notice of Commencement (NOC) and the substance has not been 
added to the Inventory, no other person may commence such activities 
without first submitting a PMN. For 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 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, 23 
of the 26 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 

[[Page 45080]]
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 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 record for this rule (OPPTS-50622).

X. Rulemaking Record

    A record has been established for this rulemaking under docket 
number OPPTS-50622 (including comments and data submitted 
electronically as described below). A public version of this record, 
including printed, paper versions of electronic comments, which does 
not include any information claimed as CBI, is available for inspection 
from 12 noon to 4 p.m., Monday through Friday, excluding legal 
holidays. The public record is located in the TSCA Nonconfidential 
Information Center, Rm. NE-B607, 401 M St., SW., Washington, DC 20460.
    Electronic comments can be sent directly to EPA at:
    [e-mail]

    Electronic comments must be submitted as an ASCII file avoiding the 
use of special characters and any form of encryption.
    The official record for this rulemaking, as well as the public 
version, as described above will be kept in paper form. Accordingly, 
EPA will transfer all comments received electronically into printed, 
paper form as they are received and will place the paper copies in the 
official rulemaking record which will also include all comments 
submitted directly in writing. The official rulemaking record is the 
paper record maintained at the address in ``ADDRESSES'' at the 
beginning of this document.

XI. Regulatory Assessment Requirements

A. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to all the requirements of the Executive Order 
(i.e., Regulatory Impact Analysis, review by the Office of Management 
and Budget (OMB)). Under section 3(f), the order defines a 
``significant regulatory action'' as an action likely to lead to a 
rule:
    (1) Having an annual effect on the economy of $100 million or more, 
or adversely and materially affecting a sector of the economy, 
productivity, competition, jobs, the environment, public health or 
safety, or State, local or tribal governments or communities (``also 
referred to as economically significant'').
    (2) Creating serious inconsistency or otherwise interfering with an 
action taken or planned by another agency.
    (3) Materially altering the budgetary impacts of entitlement, 
grants, user fees, or loan programs or the rights and obligations of 
recipients thereof.
    (4) Raising novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
this Executive Order.
    Pursuant to the terms of this Executive Order, it has been 
determined that this rule is not ``significant'' and is therefore not 
subject to OMB review.

B. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act (5 U.S.C. 605(b)), EPA has 
determined that this rule would not have a significant impact on a 
substantial number of small businesses. EPA has determined that 
approximately 10 percent of the parties affected by this rule could be 
small businesses. However, EPA expects to receive few SNUNs for these 
substances. Therefore, EPA believes that the number of small businesses 
affected by this rule will not be substantial, even if all of the SNUR 
notice submitters were small firms.

C. Paperwork Reduction Act.

    OMB has approved the information collection requirements contained 
in this rule under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), and has assigned OMB control number 2070-0012. 
Public reporting burden for this collection of information is estimated 
to vary from 30 to 170 hours per response, with an average of 100 hours 
per response, including time for reviewing instructions, searching 
existing data sources, gathering and maintaining the data needed, and 
completing and reviewing the collection of information.
    Send comments regarding the burden estimate or any other aspect of 
this collection of information, including suggestions for reducing this 
burden, to Chief, Information Policy Branch (2131), U.S. Environmental 
Protection Agency, 401 M St., SW., Washington, DC 20460; and to Office 
of Information and Regulatory Affairs, Office of Management and Budget, 
Washington, DC 20503, marked ``Attention: Desk Officer for EPA.'' The 
final rule will respond to any OMB or public comments on the 
information requirements contained in this final rule.
