### PART 52-APPROVAL AND PROMULGATION OF IMPLEMENTATION PLANS

Miscellaneous Amendments OnMay31, 1972 (37 F.R. 10842), pursuantto section 110 of the CleanAir Act and 40 CFR Part 51, the Administrator approved, with specific exceptions, State plansforimplementation ofthenational 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,In

### diana, 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 onthe basis offurther review and evaluation by the Administrator subsequent to the issuance ofthe approval/disapproval notices.

The revisions for Alaska arebased on the information presented In the implementation plan which was submitted on April 25, 1972, but could not be completely evaluated Intime forinclusion in the May 31 approval/disapproval notice, and on supplemental information submitted bythe Governor onJune 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 existsfor notpublishing these regulations as a notice ofproposed rule making andfor making them effective immediately upon publication, for the following reasons: (1) The implementation plans were prepared, adopted, and submitted bythe 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 foradequate publicparticipation through notice, public hearings, and time for comment, and consequently further public participation is unnecessary.

Dated: July 13,1972. WILLIA. D.RUCKELSHAUS, Administrator, EnvironmentalProtection Agency. Part 52 of Chapter I, Title 40 of the Code ofFederal Regulations is amended
as follows: Subpart A-General Provisions 1. In §52.02, paragraph (e) Is amended by adding anewthird sentence
as follows: § 52.02 Introduction.

* $ * * * (e) * * Except as otherwise specified, all supplemental Information submitted to theAdministrator with respect to any plan has been submitted by the Governor ofthe State.
Subpart C-Alaskx 2. Section 52.70 is amended by adding paragraph (c) as follows: § 52.70 Identification ofplan.
* * * 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 theplan aregulationprohibitingidlingofunattendedmotor vehicles. However, the plan stated that this regulation was included for informationalpurposes only,and wasnot 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.

(ii) Authority to require installatioi of monitoring devices is Inadequate (§ 51.11(a) (6) ofthis chapter).

(iii) Authority to make emission data available to the public is inadequate (§ 51.11(a) (6) of this chapter).

(iv) Authority to obtaininjunctions 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).

(iv) Authority tomake 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 fornecessary transportation control is not set forth nor Is a timetable for obtaining It Included (§ 51.11(b) ofthis chapter). §§ 52.75-52.79 [Revoked] 6. Section 52.75isrevoked. 7.
