Ethane, 1,1,1,2,2-pentafluoro-;

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 ethane, 1,1,1,2,2-pentafluoro-, based

on receipt of new data. The data

indicate that for purposes of TSCA

section 5, the substance will not present

an unreasonable risk to human health.

DATES: Written comments must be

received by January 12, 1996.

ADDRESSES: All comments must 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.

Comments that are confidential must

be clearly marked confidential business

information (CBI). If CBI is claimed, an

additional sanitized copy must also be

submitted. Nonconfidential versions of

comments on this proposed rule will be

placed in the rulemaking record and

will be available for public inspection.

Comments should include the docket

control number. The docket control

number for the chemical substance in

this SNUR is OPPTS-50601G. Unit III of

this preamble contains additional

information on submitting comments

containing CBI.

Comments and data may also be

submitted electronically by sending

SUPPLEMENTARY INFORMATION: In the

Federal Register of September 23, 1992

(57 FR 44064), EPA issued a SNUR

(FRL–4001–2) establishing significant

new uses for ethane, 1,1,1,2,2-

pentafluoro-. 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 ethane, 1,1,1,2,2-

pentafluoro- 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 in Unit IV

of this preamble.

PMN Number: P–91–1392

Chemical name: Ethane, 1,1,1,2,2-

pentafluoro-.

CAS Registry Number: Not available.

Effective date of revocation of section

5(e) consent order: February 21, 1995.

Basis for revocation of section 5(e)

consent order: The order was revoked

based on test data submitted under the

terms of the consent order. Based on the

Agency’s analysis of the submitted data,

EPA can no longer support a finding

that the manufacture, processing,

distribution in commerce, use, or

disposal of the PMN substance may

present an unreasonable risk to human

health. Accordingly, EPA has

determined that further regulation

under section 5(e) is not warranted at

this time.

Toxicity testing results: The PMN

substance P–91–1392 was tested in a

cardiac sensitization study (epinephrine

challenge in dogs), a 90-day inhalation

toxicity study in rats, and a

developmental inhalation toxicity study

(rats and rabbits). The 90-day

subchronic study showed that there

were no observable adverse effects at

concentrations up to 50,000 parts per

million (ppm). There were no observed

developmental toxicity effects at

concentrations up to 50,000 ppm in the

developmental toxicity study. There

was evidence of maternal toxicity at

50,000 ppm but no maternal effects

noted at 15,000 ppm. The PMN

substance P–91–1392 was found to be a

cardiac sensitizer when exposures

occurred at a 10 percent concentration

in air (100,000 ppm) for 10 minutes.

Lower exposures did not elicit a

sensitization response.

CFR Number: 40 CFR 721.3240

II. Background and Rationale for

Proposed Revocation of the Rule

During review of the PMN submitted

for the chemical substance that is the

subject of this proposed 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
64010 Federal Register / Vol. 60, No. 239 / Wednesday, December 13, 1995 / Proposed Rules

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 concluded that,

for the purposes of TSCA section 5, the

substance will not present an

unreasonable risk and consequently

revoked the section 5(e) consent order.

The proposed 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 proposing

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. 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 will

be treated in accordance with the

procedures in 40 CFR part 2. Any party

submitting comments claimed to be

confidential must prepare and submit a

public version of the comments that

EPA can place in the public file.

IV. Rulemaking Record

The record for the rule which EPA is

proposing to revoke was established at

OPPTS–50601 (P–91–1392). This record

includes information considered by the

Agency in developing the rule and

includes the test data that formed the

basis for this proposal.

A record has been established for this

rulemaking under docket number

OPPTS–50601G (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, excluding 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:

ncic@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 proposing to revoke 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.).

published a final rule amending Federal

Motor Vehicle Safety Standard (FMVSS)

No. 121 to require medium and heavy

vehicles to be equipped with an antilock

brake system (ABS) (60 FR 13216). The

final rule also required that these
