The Proposal

The FAA is considering an

amendment to part 71 of the Federal

Aviation Regulations (14 CFR part 71) to

establish Class E airspace at Monte

Vista, Colorado, to accommodate a new

GPS SIAP to the Monte Vista Municipal

Airport. The area would be depicted on

aeronautical charts for pilot reference.

The coordinates for this airspace docket

are based on North American Datum 83.

Class E airspace areas extending upward

from 700 feet or more above the surface

of the earth are published in Paragraph

6005 of FAA Order 7400.9D dated

September 4, 1996, and effective

September 16, 1996, which is

incorporated by reference in 14 CFR

71.1 The Class E airspace designation

listed in this document would be

published subsequently in the Order.

The FAA has determined that this

proposed regulation only involves an

established body of technical

regulations for which frequent and

routine amendments are necessary to

keep them operationally current. It,

therefore, (1) is not a ‘‘significant

regulatory action’’ under Executive

Order 12866; (2) is not a ‘‘significant

rule’’ under DOT Regulatory Policies

and Procedures (44 FR 11034; February

26, 1979); and (3) does not warrant

preparation of a regulatory evaluation as

the anticipated impact is so minimal.

Since this is a routine matter that will

only affect air traffic procedures and air

navigation, it is certified that this rule,

when promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

ENVIRONMENTAL PROTECTION

AGENCY

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.
