Federal Register / Vol. 62, No. 205 / Thursday, October 23, 1997 / Proposed Rules 55203

Visibility and Ecosystems Protection

Group (MD–15), Research Triangle Park,

NC 27707.

SUPPLEMENTARY INFORMATION: Proposed

revisions to the existing visibility

regulations (40 CFR part 51.300–51.307)

to address regional haze were published

on July 31, 1997 and originally provided

that the comment period would close on

October 20, 1997. In writing and at the

September 18, 1997 public hearing in

Denver, Colorado, a number of

commenters requested an extension of

the public comment period for the

proposed regional haze regulations. In

response to these requests, and in order

to provide the public more time to better

understand and formulate comment on

these proposed regulations, EPA is

therefore reopening the public comment

period on these proposed revisions to 40

CFR part 51.

Dated: October 10, 1997.

Richard D. Wilson,

Acting Assistant Administrator for Air and

Radiation.

Approval and Promulgation of

Implementation Plan; Minnesota

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: The United States

Environmental Protection Agency (EPA)

proposes full approval of Minnesota’s

1993 carbon monoxide (CO) emission

inventory. The inventory was submitted

by the State of Minnesota to satisfy a

certain Federal requirement that those

States containing CO nonattainment

areas (NAA’s) classified moderate and

serious to submit a revised emission

inventory (i.e., from the 1990 base year

inventory) at the end of each 3 year

period thereafter, until the area is

redesignated to attainment, of actual CO

season emissions from all sources in

accordance with EPA guidance. In the

final rules section of this Federal

Register, the EPA is approving these

actions as a direct final rule without

prior proposal because EPA views these

actions as noncontroversial and

anticipates no adverse comments. A

detailed rationale for the approval is set

forth in the direct final rule. If no

adverse comments are received in

response to that direct final rule, no

further activity is contemplated in

relation to this proposed rule. If EPA

receives substantive adverse comments

which have not already been responded

to, the direct final rule will be

withdrawn and all public comments

received will be addressed in a

subsequent final rule based on the

proposed rule. EPA will not institute a

second comment period on this action.

Any parties interested in commenting

on this action should do so at this time.

DATES: Comments on this proposed rule

must be received on or before November

24, 1997.

ADDRESSES: Comments may be mailed to

Carlton T. Nash, Chief, Regulation

Development Section, Air Programs

Clean Air Act Promulgation of

Extension of Attainment Date for

Ozone Nonattainment Area; Kentucky;

Indiana

AGENCY: Environmental Protection

Agency (USEPA).

ACTION: Proposed rule.

SUMMARY: The U.S. Environmental

Protection Agency (USEPA) is

proposing to extend the attainment date

for the Louisville interstate moderate

ozone nonattainment area from

November 15, 1996, to November 15,

1997. This extension is based in part on

monitored air quality readings for the

national ambient air quality standard

(NAAQS) for ozone during 1996. In the

final rules section of this Federal

Register, the USEPA is approving these

actions as a direct final rule without

prior proposal because USEPA views

these actions as noncontroversial and

anticipates no adverse comments. A

detailed rationale for the approval is set

forth in the direct final rule. If no

adverse comments are received in

response to that direct final rule, no

further activity is contemplated in

relation to this proposed rule. If USEPA

receives substantive adverse comments

which have not already been responded

to, the direct final rule will be

withdrawn and all public comments

received will be addressed in a

subsequent final rule based on the

proposed rule. USEPA will not institute

a second comment period on this action.

Any parties interested in commenting

on this action should do so at this time.

DATES: Comments on this proposed rule

must be received on or before November

24, 1997.
