PART 52-APPROVAL AND PROMULGATION OF IMPLEMENTATION

PLANS

Miscellaneous Amendments

On May 31, 1972 (37 F.R. 10842), pursuant to section 110 of the Clean Air Act

and 40 CFR Part 51, the Administrator

approved, with specific exceptions, State

plans for implementation of the national

ambient air quality standards. These

amendments incorporate corrections

and clarifications of the approvals and

disapprovals. In addition, these amendments include revisions to the approval/

disapproval notices resulting from supplemental information submitted to the

Administrator by the States to correct

disapproved portions of their plans

and from further evaluation by the

Administrator.

Arizona, Delaware, Hawaii, Idaho, Indiana, Kentucky, Montana, Nebraska,

Nevada, Ohio, Pennsylvania, and Virginia submitted supplemental information which permitted approval of certain portions of their plans that had

formerly been disapproved.

The approval or disapproval of certain portions of the plans for Arizona,

Hawaii, Idaho, Maine, Montana, Nevada,

New Mexico, Rhode Island, Utah, and

Vermont are revised on the basis of further review and evaluation by the Administrator subsequent to the issuance

of the approval/disapproval notices.

The revisions for Alaska are based on

the information presented In the implementation plan which was submitted on

April 25, 1972, but could not be completely evaluated In time for inclusion in

the May 31 approval/disapproval notice,

and on supplemental information submitted by the Governor on June 22, 1972.

These regulations are effective on the

date of their publication in the FEDERAL

REGISTEr (7-27-72). The Agency finds

that good cause exists for not publishing

these regulations as a notice of proposed

rule making and for making them effective immediately upon publication, for

the following reasons:

(1) The implementation plans were

prepared, adopted, and submitted by the

States, and reviewed and evaluated by

the Administrator pursuant to 40 CFR

Part 51, which, prior to promulgation,

had been published as a notice of proposed rule making for comment by

interested persons, and

(2) The approved .implementation

plan provisions were adopted In accordance with procedural requirements of

State and Federal law, which provided

for adequate public participation through

notice, public hearings, and time for

comment, and consequently further

public participation is unnecessary.

Dated: July 13,1972.

WILLIA. D. RUCKELSHAUS,

Administrator,

Environmental Protection Agency.

Part 52 of Chapter I, Title 40 of the

Code of Federal Regulations is amended

as follows:

Subpart A-General Provisions

1. In § 52.02, paragraph (e) Is

amended by adding a new third sentence

as follows:

§ 52.02 Introduction. * $ * * *

(e) * * Except as otherwise specified, all supplemental Information submitted to the Administrator with respect

to any plan has been submitted by the

Governor of the State.

Subpart C-Alaskx

2. Section 52.70 is amended by adding

paragraph (c) as follows:

§ 52.70 Identification of plan. * * * S $

c) Supplemental information was

submitted on June 22, 1972.

3. Section 52.72 is revised to read as

follows:

§ 52.72 Approval status.

With the exceptions set forth in this

subpart, the Administrator approves

Alaska's plan for the attainment and

maintenance of the national standards.

The State included in the plan a regulation prohibiting idling of unattended motor vehicles. However, the plan stated

that this regulation was included for

informational purposes only, and was not

to be considered part of the control

strategy to implement the national

standards for carbon monoxide. Accordingly, this regulation is not considered

a part of the applicable plan.

§ 52.73 [Revoked]

4. Section 52.73 is revoked.

5. Section 52.74 is revised to read as

follows:

§ 52.74 Legal authority.

(a) The requirements of § 51.11 of this

chapter are not met since In:

(1) Cook Inlet Air Resources Management District:

(t) Authority to require recordkeeplng

is inadequate ( 51.11(a) (5) of this

chapter).

(ii) Authority to require installatioi

of monitoring devices is Inadequate

(§ 51.11(a) (6) of this chapter).

(iii) Authority to make emission data

available to the public is inadequate

(§ 51.11(a) (6) of this chapter).

(iv) Authority to obtain injunctions Is

inadequate (§ 51.11(a) (2) of this chapter).

(2) Fairbanks North Star Borough:

(i) Authority to obtain injunctions Is

inadequate (§ 51.11 (a) (2) of this chapter).

(1i) Authority to require recordkeepIng is inadequate (§ 51.11(a) (5) of this

chapter).

(iII) Authority to require installation

of monitoring devices is Inadequate

(§ 51.11 (a) (6) of this chapter).

(iv) Authority to make emissions data

available to the public is Inadequate

since 45.05130 of the Fairbanks North

Star Borough ordinance could require It

to be confidential (§ 51.11 (a) (6) of this

chapter).

(v) Authority to abate emergency air

pollution episodes is inadequate because

45.05.100 of the Fairbanks North Star

Borough ordinance is limited to generalized conditions of air pollution and because the order of the Commission Is

subject to review de novo (§ 51.11(a) (3)

of this chapter).

(vi) Authority for necessary transportation control is not set forth nor Is a

timetable for obtaining It Included

(§ 51.11(b) of this chapter).

51.22 of this chapter are not met since

the plan does not Impose specific emission limitations on copper smelters in

the Phoenix-Tucson Intrastate Region

and the Arizona portion of the ArizonaNew Mexico Southern Border Interstate

Region. In addition, the plan does not

require permanent control of emissions

from copper smelters necessary to

achieve all national standards for sulfur

oxides. Therefore, Regulation 7-1-4.1

(copper smelters) of the Arizona Rules

control necessary to attain and maintain the national standards for particulate matter in the Phoenix-Tucson

Intrastate Region. Therefore, Regulation 7-1-3.6 (process Industries) of the

Arizona Rules and Regulations for Air

Pollution Control, Rule 31(E) (process industries) in Regulation I of the

Maricopa County Air Pollution Control

Rules and Regulations, and Rule 2(B)

monoxide and" are added after the word

"source" in the first sentence in para- graph (a) (1).

23. In Subpart D, § 52.133 is added as follows:

§ 52.133 Rules and regulations.

(a) Regulation 7-1-1.4(A) (excep- tions) provides for an exemption from

enforcement action if the violation is

attributable to certain events. These

events are too broad in scope and the source can obtain the exemption merely by reporting the occurrence. Therefore,

Regulations 7-1-1.4(A) of the Arizona

Rules and Regulations for Air Pollution

Control is disapproved since this reg- ulation makes all approved emission

limiting regulations potentially unenforceable.

Subpart I-Delaware

this chapter are not met since increments

of progress towards compliance are not

provided for in section 12(b) (compli- ance schedule for bagasse-burning

boilers) of the Hawaii Air Pollution Control Regulations. Therefore, section 12

(b) of the Hawaii Air Pollution Control

Regulations, as It pertains to existing

particulate matter in the Metropolitan Indianapolis Intrastate Region.

(b) APC 4-R of Indiana's "Air Pollution Control Regulations" (emission limitation for particulate matter from

fuel combustion sources), which is part of the control strategy for the secondary standards for particulate matter, is disapproved for the Metropolitan Indianapolis Intrastate Region since it does not

provide the degree of control needed to
