40 CFR Part 721

[OPPTS-50582K; FRL-4746-3]

 

2,5-Dimercapto-1,3,4-Thiadiazole, Alkyl Polycarboxylate; 
Revocation of a Significant New Use Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final 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 2,5-dimercapto-1,3,4-thiadiazole, alkyl polycarboxylate 
based on receipt of new data. The data indicate that the substance will 
not present an unreasonable risk to health.

EFFECTIVE DATE: The effective date of this rule is May 13, 1994.

FOR FURTHER INFORMATION CONTACT: Susan B. Hazen, Director, 
Environmental Assistance Division (7408), Office of Pollution 
Prevention and Toxics, Environmental Protection Agency, Rm. E-543A, 401 
M St., SW., Washington, DC 20460, Telephone: (202) 554-1404, TDD: (202) 
554-0551.

SUPPLEMENTARY INFORMATION: In the Federal Register of August 15, 1990 
(55 FR 33296), EPA issued a SNUR establishing significant new uses for 
2,5-dimercapto-1,3,4-thiadiazole, alkyl polycarboxylate (P-88-1460). 
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 15, 1993 (58 FR 48346). 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. Rationale for Revocation of the Rule

    During review of the PMN submitted for the chemical substance that 
is the subject of this 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 EPA identified the tests considered 
necessary to evaluate the risks of the substance. The basis for such 
findings is referenced in Unit I. of this preamble. 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 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 subsequently revoked the 
section 5(e) consent order. The revocation of SNUR provisions for this 
substance designated herein is consistent with the revocation of the 
section 5(e) order.
    In light of the above, EPA is revoking 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 proposing to revoke was 
established at OPPTS-50582 (P-88-1460). This record includes 
information considered by the Agency in developing this rule and 
includes the test data that form the basis for this rule.

IV. Regulatory Assessment Requirements

    EPA is proposing to revoke the requirements of this rule. Any costs 
or burdens associated with this rule will 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.).
