40 CFR Part 721

[OPPTS-50620B; FRL-5723-4]
RIN 2070-AB27


Butanamide, 2,2'-[3'dichloro[1,1'-biphenyl]-4,4'-diyl) bisazobis 
N-2,3-dihydro-2-oxo-1H-benximdazol-5-yl)-3-oxo-; Proposed Significant 
New Use Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing a significant new use rule (SNUR) under 
section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the 
chemical substance described as butanamide, 2,2'-[3'dichloro[1,1'-
biphenyl]-4,4'-diyl)bisazobis N-2,3-dihydro-2-oxo-1H-benximdazol-5-yl)-
3-oxo- which is the subject of premanufacture notice (PMN) P-93-1111. 
This proposal would require certain persons who intend to manufacture, 
import, or process this substance for a significant new use to notify 
EPA at least 90 days before commencing any manufacturing, importing, or 
processing activities for a use designated by this SNUR as a 
significant new use. The required notice would provide EPA with the 
opportunity to evaluate the intended use and, if necessary, to prohibit 
or limit that activity before it can occur.

DATES: Written comments must be received by EPA by July 28, 1997.

ADDRESSES: Each comment must bear the docket control number OPPTS-
50620B. All comments should be sent in triplicate to: OPPT Document 
Control Officer (7407), Office of Pollution Prevention and Toxics, 
Environmental Protection Agency, Rm. ET-G099, 401 M St., SW., 
Washington, DC 20460.
    Comments and data may also be submitted electronically by following 
the instructions under Unit VIII of this

[[Page 34425]]

document. No confidential business information (CBI) should be 
submitted through e-mail.
    All comments which are claimed confidential must be clearly marked 
as such. Three additional sanitized copies of any comments containing 
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. See Unit VII for further information.

FOR FURTHER INFORMATION CONTACT: Susan Hazen, Director, Environmental 
Assistance Division (7408), Office of Pollution Prevention and Toxics, 
Environmental Protection Agency, Rm. E-543B, 401 M St., SW., 
Washington, DC 20460, telephone: (202) 554-1404, TDD: (202) 554-0551.
SUPPLEMENTARY INFORMATION: This proposed SNUR would require persons to 
notify EPA at least 90 days before commencing the manufacture, import, 
or processing of P-93-1111 for the significant new uses designated 
herein. The required notice would provide EPA with information with 
which to evaluate an intended use and associated activities.

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 
chemical substance for that use. Section 26(c) of TSCA authorizes EPA 
to take action under section 5(a)(2) with respect to a category of 
chemical substances.
    Persons subject to this SNUR would comply with the same notice 
requirements and EPA regulatory procedures as submitters of 
premanufacture notices under section 5(a)(1) of TSCA. In particular, 
these requirements include the information submission requirements of 
section 5(b) and (d)(1), the exemptions authorized by section 5(h)(1), 
(h)(2), (h)(3), and (h)(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 for which it has 
received a SNUR notice. If EPA does not take action, section 5(g) of 
TSCA requires EPA 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.

II. Applicability of General Provisions

    General regulatory provisions applicable to SNURs are codified at 
40 CFR part 721, subpart A. On July 27, 1988 (53 FR 28354) and July 27, 
1989 (54 FR 31298), EPA promulgated amendments to the general 
provisions which apply to this SNUR. In the Federal Register of August 
17, 1988 (53 FR 31252), EPA promulgated a ``User Fee Rule'' (40 CFR 
part 700) under the authority of TSCA section 26(b). Provisions 
requiring persons submitting SNUR notices to submit certain fees to EPA 
are discussed in detail in that Federal Register document. Interested 
persons should refer to these documents for further information.

III. Background

    EPA published a direct final SNUR for the chemical substance, which 
was the subject of PMN P-93-1111 in the Federal Register of March 1, 
1995 (60 FR 11033) (FRL-4868-4). EPA received comments following 
publication for this chemical substance. Therefore, as required by 
Sec. 721.160, the final SNUR for P-93-1111 is being withdrawn elsewhere 
in this issue of the Federal Register and this proposed rule on the 
substance is being issued. The commenter stated that one statement 
required on the Material Safety Data Sheet (MSDS) and label in the 
section 5(e) consent order was not required in the SNUR while several 
statements required in the SNUR were not required in the order. EPA has 
changed the proposed SNUR so that its hazard communication requirements 
match those of the section 5(e) consent order.

IV. Substance Subject to This Rule

    EPA is proposing significant new use and recordkeeping requirements 
for the following chemical substance under part 721 subpart E.

PMN Number P-93-1111

Chemical name: Butanamide, 2,2'-[3'dichloro[1,1'-biphenyl]-4,4'-
diyl)bisazobis N-2,3-dihydro-2-oxo-1H-benximdazol-5-yl)-3-oxo-.
CAS number: 78245-94-0.
Effective date of section 5(e) consent order: May 27, 1994.
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 and the environment.
Toxicity concern: Structurally similar chemicals have been shown to 
cause carcinogenicty and mutagenicity in test animals and toxicity to 
aquatic organisms.
Recommended testing: The following data are recommended to help 
characterize the PMN substance's potential to cause human health and 
environmental effects: Monitoring data to detect the presence of 
dichlorobenzidine (DCB) under actual conditions of use; monitoring data 
to detect airborne concentrations of DCB; monitoring data on releases 
of DCB to surface waters. (See Agency guidelines and information on 
performing monitoring studies.) Also recommended to help determine the 
PMN substance's potential to cause environmental effects: An anaerobic 
biodegradation study (OPPTS 835.3400 test guideline (public draft)).
CFR citation: 40 CFR 721.1907.

V. Applicability of SNUR to Uses Occurring Before Effective Date of 
the Final SNUR

    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 
proposal rather than as of the effective date of the rule. Because this 
SNUR was first published on March 1, 1995, as a direct final rule, that 
date will serve as the date after which uses would be considered to be 
new uses. If uses which had commenced between that date and the 
effective date of this rulemaking were considered ongoing, rather than 
new, any person could defeat the SNUR by initiating a significant new 
use before the effective date. This would make it difficult for EPA to 
establish SNUR notice requirements. Thus, persons who begin commercial 
manufacture, import, or processing of the substance for uses that would 
be regulated through this SNUR after March 1, 1995, would have to cease 
any such activity before the effective date of this rule. To resume 
their activities, such persons would have to comply with all applicable 
SNUR notice requirements and wait until the notice review period, 
including all extensions, expires. EPA, not wishing to unnecessarily 
disrupt the activities of persons who begin commercial manufacture, 
import, or processing for a proposed significant new use before the 
effective date of the SNUR, has promulgated provisions to allow such 
persons to comply with this proposed SNUR before it is promulgated. If 
a person were to meet the conditions of advance compliance as

[[Page 34426]]

codified at Sec. 721.45(h) (53 FR 28354, July 17, 1988), 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 proposal 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.

VI. 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 at the time of the direct final 
rule. The analysis is unchanged for the substance in this proposed 
rule. The Agency's complete economic analysis is available in the 
public record for this proposed rule (OPPTS-50620B).

VII. Comments Containing Confidential Business Information

    Any person who submits comments containing information claimed as 
confidential business information must mark the comments as 
``confidential,'' ``trade secret,'' or other appropriate designation. 
Comments not claimed as confidential at the time of submission will be 
placed in the public file without further notice to the submitter. Any 
comments marked as confidential will be treated in accordance with the 
procedures in 40 CFR part 2. Any party submitting comments claimed to 
be confidential must prepare and submit a nonconfidential public 
version in triplicate of the comments that EPA can place in the public 
file.

VIII. Rulemaking Record

     The official record for this rulemaking, as well as the public 
version, has been established for this rulemaking under docket number 
OPPTS-50620B (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 confidential business information (CBI), is 
available for inspection from 12 noon to 4 p.m., Monday through Friday, 
excluding legal holidays. The official rulemaking record is located in 
the TSCA Nonconfidential Information Center, Rm. NE-B607, 401 M St., 
SW., Washington, DC.
    Electronic comments can be sent directly to EPA at:
    [email protected]


    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-50620B. Electronic comments on 
this proposed rule may be filed online at many Federal Depository 
Libraries.
    The OPPTS harmonized test guidelines referenced in this document 
are available on EPA's World Wide Web site under ``Researchers and 
Scientists,'' ``Environmental Test Methods & Guidelines'' (http://
www.epa.gov/epahome/research.htm).

IX. Regulatory Assessment Requirements

    Under Executive Order 12866 (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 of 1995 (Pub. L. 104-4), 
or require prior consultation with State officials as specified by 
Executive Order 12875 (58 FR 58093, October 28, 1993), or involve 
special considerations of environmental justice related issues as 
required by Executive Order 12898 (59 FR 7629, February 16, 1994).
    An agency may not conduct or sponsor, and a person is not required 
to respond to, an information collection request unless it displays a 
currently valid OMB control number. The information collection 
requirements related to this action have already been approved by OMB 
pursuant to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., 
under OMB control number 2070-0012 (EPA ICR No. 574). This action does 
not impose any burdens requiring additional OMB approval. The public 
reporting burden for this collection of information is estimated to 
average 100 hours per response. The burden estimate includes the time 
needed to review instructions, search existing data sources, gather and 
maintain the data needed, and complete and review the collection of 
information.
    In addition, pursuant to section 605(b) of the Regulatory 
Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency has determined 
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.

X. 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 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).
