ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 721
[OPPTS-50583I; FRL-4755-9]
Substituted Triazine Isocyanurate; Revocation of a Significant
New Use Rule
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to revoke a significant new use rule (SNUR)
promulgated under section 5(a)(2) of the Toxic Substances Control Act
(TSCA) for substituted triazine isocyanurate based on receipt of new
data. The data indicate that, for purposes of section 5 of TSCA, the
substance will not present an unreasonable risk to the environment.
DATES: Written comments must be received by EPA by September 1, 1994.
ADDRESSES: All comments must be sent in triplicate to: U.S.
Environmental Protection Agency, ATTN: OPPT Document Receipt Office
(7407), 401 M St., SW., Rm. E-G99, Washington, DC 20460. Comments that
are confidential must be clearly marked confidential business
information (CBI). If CBI is claimed, three additional sanitized copies
must also be submitted. Nonconfidential versions of comments on this
proposed rule will be placed in the rulemaking record and will be
available for public inspection. Comments should include the docket
control number. The docket control number for the chemical substance in
this SNUR is OPPTS-50583I. Unit III. of this preamble contains
additional information on submitting comments containing CBI.
FOR FURTHER INFORMATION CONTACT: Susan B. Hazen, Director,
Environmental Assistance Division (7408), Office of Pollution
Prevention and Toxics, Environmental Protection Agency, Rm. E-543B, 401

554-0551.
SUPPLEMENTARY INFORMATION: In the Federal Register of August 9, 1990
(55 FR 32406), EPA issued a SNUR establishing significant new uses for
substituted triazine isocyanurate. Because of additional data EPA has
received for this substance, EPA is proposing to revoke this SNUR.
I. Proposed Revocation
EPA is proposing to revoke the significant new use and
recordkeeping requirements for substituted triazine isocyanurate under
40 CFR part 721 subpart E. In this unit, EPA provides a brief
description for the substance, including its PMN number, chemical name
(generic name if the specific name is claimed as CBI), CAS number (if
assigned), basis for the revocation of the section 5(e) consent order
for the substance, and the CFR citation removed in the regulatory text
section of this proposed rule. Further background information for the
substance is contained in the rulemaking record referenced in Unit IV.
of this preamble.
PMN Number P-86-66
Chemical name: (generic) Substituted triazine isocyanurate.
CAS number: Not available.
Effective date of revocation of section 5(e) consent order: December
13, 1993.
Basis for revocation of section 5(e) consent order: The order was
revoked based on test data submitted under the terms of the consent
order. Based on the Agency's analysis of the submitted data, EPA has
sufficient information to determine for purposes of TSCA section 5,
that the manufacture, processing, distribution in commerce, use, or
disposal of the PMN substance will not present an unreasonable risk to
the human health. Accordingly, EPA has determined that further
regulation under section 5(e) is not warranted at this time.
Toxicity testing results: An acute oral gavage study of rats with a 14-
day observation and neurotoxicity functional observational battery
demonstrated a no observed adverse effect level of 1,000 mg/kg and a
low observed adverse effect level of 2,000 mg/kg for decreased forelimb
and hindlimb grip strength.
CFR citation: 40 CFR 721.9760.
II. Objectives and Rationale for Proposed Revocation of the Rule
During review of the PMN submitted for the chemical substance that
is the subject of this proposed revocation, EPA concluded that
regulation was warranted under section 5(e) of TSCA pending the
development of information sufficient to make a reasoned evaluation of
the health effects of the substance, and that the substance may present
an unreasonable risk of injury to human health. EPA identified the
tests considered necessary to make a reasoned evaluation of the risks
posed by the substance to human health. Based on these findings, a
section 5(e) consent order was negotiated with the PMN submitter and a
SNUR was promulgated. EPA reviewed testing which was conducted by the
PMN submitter pursuant to the 5(e) consent order for the substance and
determined that the information available was sufficient to make a
reasoned evaluation of the health effects of the substance. EPA
concluded that, for the purposes of TSCA section 5, the substance will
not present an unreasonable risk and consequently revoked the section
5(e) consent order. The proposed revocation of SNUR provisions for the
substance designated herein is consistent with the revocation of the
section 5(e) order. In light of the above, EPA is proposing a
revocation of SNUR provisions for this chemical substance. EPA will no
longer require notice of any company's intent to manufacture, import,
or process this substance. In addition, export notification under
section 12(b) of TSCA will no longer be required.
III. Comments Containing Confidential Business Information
Any person who submits comments claimed as CBI 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. 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 public version of the comments that EPA can
place in the public file.
IV. Rulemaking Record
The record for the rule which EPA is proposing to revoke was
established at OPPTS-50583 (P-86-66). This record includes information
considered by the Agency in developing the rule and includes the test
data that formed the basis for this proposal.
V. Regulatory Assessment Requirements
EPA is proposing to revoke the requirements of the rule. Any costs
or burdens associated with the rule will also be eliminated when the
rule is revoked. Therefore, EPA finds that no costs or burdens must be
assessed under Executive Order 12866, the Regulatory Flexibility Act (5
U.S.C. 605(b)), or the Paperwork Reduction Act (44 U.S.C. 3501 et
seq.).
