40 CFR Part 721

[OPPTS–50622A; FRL–5580–7]

Aliphatic Ester; Proposed 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 aliphatic ester based on a new

evaluation of toxicity data. Based on the

data the Agency determined that it

could no longer support a finding that

activities not described in the TSCA

section 5(e) consent order may result in

significant changes in human exposure.

DATES: Written comments must be

received by March 6, 1997.

ADDRESSES: Each comment must bear

the docket control number OPPTS–

50622A. All comments should be sent

in triplicate to: OPPT Document Control

Officer (7407), Office of Pollution

Prevention and Toxics, Environmental

Protection Agency, 401 M Street, SW.,

Room G–099, East Tower, Washington,

DC 20460.

All comments which are claimed

confidential must be clearly marked as

such. Three additional sanitized copies

of any comments containing

confidential business information (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.

Unit III of this preamble contains

additional information on submitting

comments containing CBI.

Comments and data may also be

submitted electronically by sending

electronic mail (e-mail) to: opptncic@epamail.epa.gov. 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 5.1

file format or ASCII file format. All

comments and data in electronic form

must be identified by (OPPTS–50622A).

No CBI should be submitted through email. Electronic comment on this notice

may be filed online at many Federal

Depository Libraries. Additional

information on electronic submissions

can be found under Unit IV of this

preamble.

SUPPLEMENTARY INFORMATION: In the

Federal Register of August 30, 1995 (60

FR 45072) (FRL–4926–2) EPA issued a

SNUR establishing significant new uses

for aliphatic ester. 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 the following chemical

substance under 40 CFR part 721,

subpart E. In this unit, EPA provides a

brief description for the substance,

including its premanufacture notice

(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 below in

Unit IV of this preamble.

PMN Number P–93–633

Chemical name: (generic) Aliphatic

ester.

CAS number: Not available.

Effective date of revocation of section

5(e) consent order: December 7, 1995.

Basis for revocation of SNUR: The

consent order which was the basis of

this SNUR was revoked based on a

reassessment of the developmental

toxicity data used in the risk assessment

of this substance. EPA’s reevaluation of

the data established a No Observed

Adverse Effect Level (NOAEL) of 250

mg/kg. Based on that assessment EPA

determined that it could no longer

support an unreasonable risk finding

under section 5(e) of TSCA and revoked

the consent order. EPA can no longer

make the finding that activities not

described in the TSCA section 5(e)

consent order may result in significant

changes in human exposure.

CFR Number: 40 CFR 721.2815.

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 based on the fact that

activities not described in the section

5(e) consent order may result in

significant changes in human exposure.

Based on these findings, a SNUR was

promulgated.

EPA has revoked the section 5(e)

consent order that is the basis for this

SNUR and determined that it could no

longer support a finding that activities

not described in the section 5(e) consent

order may result in significant changes

in human exposure. The proposed

revocation of SNUR provisions for this

substance designated herein is

consistent with this finding.

In light of the above, EPA is proposing

to revoke 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. 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 must

prepare and submit a public version of

the comments that EPA can place in the

public file.

IV. Rulemaking record

A record has been established for this

rulemaking under docket number

OPPTS 50522A (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 CBI is available for

inspection from 12 noon to 4 p.m.,

Monday through Friday, except legal

holidays. The public record is located in

the TSCA Nonconfidential Information

Center Rm. NE–B607, 401 M St., SW.,

Washington, DC 20460.

Electronic comments can be sent

directly to EPA at: opptncic@epamail.epa.gov. Electronic

comments must be submitted as an

ASCII file avoiding the use of special

characters and any form of encryption.

The official record for this

rulemaking, as well as the public

version, as described above will be kept

in paper form. Accordingly, EPA will

transfer all comments received

electronically into printed, paper form

as they are received and will place the

paper copies in the official rulemaking

record which will also include all

comments submitted directly in writing.

The official rulemaking record is the

paper record maintained at the address

in ‘‘ADDRESSES’’ at the beginning of

this document.

V. 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.).

SUPPLEMENTARY INFORMATION:

Background and Purpose

On July 7, 1995, a Conference of

Parties to the International Convention

on Standards of Training, Certification

and Watchkeeping for Seafarers, 1978

(STCW), meeting at the Headquarters of

the International Maritime Organization

in London, adopted the amendments to

the STCW. The 1995 Amendments to

STCW enter into force on February 1,

1997. In the NPRM published on March

26, 1996 (61 FR 13284), the Coast Guard

proposed a number of changes it

considered necessary to implement the

revised requirements, to ensure that

U.S. documents and licenses are issued

in compliance with the 1995

Amendments to STCW.

The STCW sets qualifications for

masters, officers, and watchkeeping

personnel on seagoing merchant ships.

It was originally adopted in 1978 by a

conference at IMO Headquarters in

London, and it entered into force in

1984. Currently, there are 119 StateParties, representing almost 95 percent

of the world’s merchant-ship tons. The

United States became a party in 1991.

Over 90 percent of ships entering U.S.

waters are foreign-flag, and most of

them are or will be subject to STCW.

Approximately 350 large U.S. merchant

ships that routinely visit foreign ports,

as well as thousands of smaller U.S.

documented commercial vessels that

operate on ocean or near-coastal

voyages, are subject to STCW.

The Amendments adopted by the

Conference in July 1995 are

comprehensive and detailed. They

concern port-state control,

communication of information to IMO

to allow for mutual oversight, and

responsibility of all State-Parties to

ensure that seafarers meet objective

standards of competence. They also

require candidates for certificates

(licenses and document endorsements)

to establish competence through both

subject-area examinations and practical
