the reducing and oxidation portions of

the combustion flame.

Flue gas recirculation line is defined

as the part of Boiler No. 100 that

recirculates a portion of the boiler flue

gas back into the combustion air.

(2) Standard for nitrogen oxides. (i)

When fossil fuel alone is combusted, the

nitrogen oxides emission limit for fossil

fuel in § 60.44b(a) applies.

(ii) When fossil fuel and chemical byproduct waste are simultaneously

combusted, the nitrogen oxides

emission limit is 473 ng/J (1.1 lb/million

Btu), and the air ratio control damper

tee handle shall be at a minimum of 5

inches (12.7 centimeters) out of the

boiler, and the flue gas recirculation line

shall be operated at a minimum of 10

percent open as indicated by its valve

opening position indicator.

(3) Emission monitoring for nitrogen

oxides. (i) The air ratio control damper

tee handle setting and the flue gas

recirculation line valve opening

position indicator setting shall be

recorded during each 8-hour operating

shift.

(ii) The nitrogen oxides emission limit

shall be determined by the compliance

and performance test methods and

procedures for nitrogen oxides in

§ 60.46b.

(iii) The monitoring of the nitrogen

oxides emission limit shall be

performed in accordance with § 60.48b.

(4) Reporting and recordkeeping

requirements. (i) The owner or operator

of Boiler No. 100 shall submit a report

on any excursions from the limits

required by paragraph (b)(2) of this

section to the Administrator with the

quarterly report required by § 60.49b(i).

(ii) The owner or operator of Boiler

No. 100 shall keep records of the

monitoring required by paragraph (b)(3)

of this section for a period of 2 years

following the date of such record.

(iii) The owner of operator of Boiler

No. 100 shall perform all the applicable

reporting and recordkeeping

requirements of § 60.49b.

40 CFR Part 721

[OPPTS–50601E; FRL–4919–7]

Pentaerythritol, Mixed Esters With

Carboxylic Acids; Revocation of a

Significant New Use Rule

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Final rule.

SUMMARY: EPA is revoking the

significant new use rule (SNUR)

promulgated under section 5(a)(2) of the

Toxic Substances Control Act (TSCA)

for pentaerythritol, mixed esters with

carboxylic acids, based on receipt of

toxicity data. The data indicate that, for

purposes of TSCA section 5, the

substance will not present an

unreasonable risk to health.

EFFECTIVE DATE: The effective date of

this rule is June 29, 1995.

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 September 23, 1992

(57 FR 44050), EPA issued a SNUR

establishing significant new uses for

pentaerythritol, mixed esters with

carboxylic acids (P–91–1250). 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 August 2, 1994 (59

FR 40001). 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 comments concerning the

proposed revocation. As a result, EPA is

revoking the 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 that the substance is expected to be

produced in substantial quantities and

there may be significant or substantial

environmental exposure. EPA identified

the tests necessary to make a reasoned

evaluation of the risks posed by the

substance to 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

section 5(e) 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 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 revoking

the SNUR provisions for this chemical

substance. 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–

50601 (P–91–1250). This record

includes information considered by the

Agency in developing this rule and

includes the test data that formed the

basis for this revocation.

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.).
