40 CFR Part 721

[OPPTS–50598B; FRL–5580–5]

Substituted Cyclohexyldiamino Ethyl

Esters; 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

substituted cyclohexyldiamino ethyl

esters based on receipt of new data.

Based on the data the Agency

determined that it could no longer

support a finding that activities not

described in the PMN may result in

significant changes in environmental

exposure.

EFFECTIVE DATE: The effective date of

this rule is March 6, 1997.

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)

SUPPLEMENTARY INFORMATION: In the

Federal Register of October 8, 1992 (57

FR 46458) (FRL–3934–7) EPA issued a

SNUR establishing significant new uses

for substituted cyclohexyldiamino ethyl

esters. Because of additional data EPA

has received for this substance, EPA is

proposing to revoke this SNUR.

I. Background

The Agency proposed the revocation

of the SNUR for this substance in the

Federal Register of April 19, 1996 (61

FR 17272) (FRL–5355–5). 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

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 § 721.170(b)(4)(ii)

based on the fact that activities not

described in the PMN may result in

significant changes in environmental

exposure. Based on these findings, a

SNUR was promulgated.

EPA has determined that it could no

longer support a finding that activities

not described in the PMN may result in

significant changes in environmental

exposure. The revocation of SNUR

provisions for this substance designated

herein is consistent with this finding.

In light of the above, EPA is revoking

the 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–

50598 (P–91–1243). This record

includes information considered by the

Agency in developing this rule.

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

this rule. Any costs or burdens

associated with this 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.).
