Cyclohexanecarbonitrile, 1,3,3-trimethyl-5-oxo-; Revocation of a 
Significant New Use Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is revoking a significant new use rule (SNUR) promulgated 
under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 
cyclohexanecarbonitrile, 1,3,3-trimethyl-5-oxo- based on receipt of new 
data. Based on the data the Agency determined that it could not support 
a

finding that activities described in the PMN may result in a 
significant risk.

EFFECTIVE DATE: The effective date of this rule is July 29, 1996.

SUPPLEMENTARY INFORMATION: In the Federal Register of September 23, 
1992 (57 FR 44050), EPA issued a SNUR (FRL-4001-2) establishing 
significant new uses for cyclohexanecarbonitrile, 1,3,3-trimethyl-5-
oxo-. Because of additional data EPA has received for this substance, 
EPA is revoking this SNUR.

I. Background

    The Agency proposed the revocation of the SNUR for this substance 
in the Federal Register of September 13, 1995 (60 FR 47531) (FRL-4926-
1). The background and reasons for the revocation of the SNUR are set 
forth in the preamble to the proposed revocation. The Agency received 
no public comment concerning the proposed revocation. As a result EPA 
is revoking this SNUR.

II. Background and Rationale for Final SNUR Revocation of the Rule

    During review of the premanufacture notice (PMN) submitted for the 
chemical substance that is the subject of this final SNUR 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 environmental effects of the substance, and that the 
substance is expected to be produced in substantial quantities and 
there may be significant or substantial human exposure. EPA identified 
the tests necessary to make a reasoned evaluation of the risks posed by 
the substance to the 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 conducted by the PMN submitter pursuant to the 
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 has determined that it could not support 
a finding that activities described in the PMN may result in a 
significant risk. The final 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 finalizing a revocation of SNUR 
provisions for this chemical substance. When this revocation becomes 
final, 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. Rulemaking Record

    The record for the rule which EPA is revoking was established at 
OPPTS-50601 (P-90-1358). This record includes information considered by 
the Agency in developing the rule and includes the test data that 
formed the basis for this finalization.
    A public version of the record, without any Confidential Business 
Information, is available in the OPPT Non-Confidential Information 
Center (NCIC) from 12 p.m. to 4 p.m., Monday through Friday, except 
legal holidays. The TSCA NCIC is located in the Northeast Mall Basement 
Rm. B-607, 401 M St., SW., Washington, DC.

IV. Regulatory Assessment Requirements

    EPA is revoking 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.).
