Approval and Promulgation of Air

Quality Implementation Plans;

Montana

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to take

direct final action partially approving

and partially disapproving State

Implementation Plan (SIP) revisions

submitted by the Governor of Montana,

on September 19, 1997, December 10,

1997, April 14, 1999, December 6, 1999

and March 3, 2000. These revisions

recodify and modify the State’s air

quality rules so that they are consistent

with Federal requirements, minimize

repetition in the air quality rules, and

clarify existing provisions. In addition,

we are also approving into the SIP

Yellowstone County’s Local Regulation

No.002—Open Burning. Finally, we are

also announcing that we delegated the

authority for the implementation and

enforcement of the New Source

Performance Standards (NSPS) to the

State. EPA is either not acting on or

disapproving certain provisions of the

State’s air quality rules that should not

be in the SIP because they are not

generally related to attainment of the

National Ambient Air Quality Standards

(NAAQS) or they are inconsistent with

our SIP requirements. Finally, some

provisions of the rules will be acted on

at a later date. This action is being taken

under section 110 and 111 of the Clean

Air Act. In the ‘‘Rules and Regulations’’

section of this Federal Register, EPA is

approving the State’s SIP revision as a

direct final rule without prior proposal

because the Agency views this as a

noncontroversial SIP revision and

anticipates no adverse comments. A

detailed rationale for the approval is set

forth in the preamble to the direct final

rule. If EPA receives no adverse

comments, EPA will not take further

action on this proposed rule. If EPA

receives adverse comments, EPA will

withdraw the direct final rule and it will

not take effect. EPA will address all

public comments in a subsequent final

rule based on this proposed rule. EPA

will not institute a second comment

period on this action. Any parties

interested in commenting must do so at

this time. Please note that if EPA

receives adverse comment on an

amendment, paragraph, or section of

this rule and if that provision may be

severed from the remainder of the rule,

EPA may adopt as final those provisions

of the rule that are not the subject of an

adverse comment.

DATES: Comments must be received in

writing on or before July 16, 2001.

ADDRESSES: Written comments may be

mailed to Richard R. Long, Director, Air

and Radiation Program, Mailcode 8PAR, Environmental Protection Agency

(EPA), Region VIII, 999 18th Street,

Suite 300, Denver, Colorado, 80202.

Copies of the documents relevant to this

action are available for public

inspection during normal business

hours at the Air and Radiation Program,

Environmental Protection Agency,

Region VIII, 999 18th Street, Suite 300,

Denver, Colorado, 80202. Copies of the

State documents relevant to this action

are available for public inspection at the

Montana Department of Environmental

Quality, Air and Waste Management

Bureau, 1520 E. 6th Avenue, Helena,

Approval and Promulgation of Air

Quality Implementation Plans;

Colorado; Designation of Areas for Air

Quality Planning Purposes, Telluride

and Pagosa Springs

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to take

direct final action to approve a State

Implementation Plan (SIP) revision

submitted by the State of Colorado on

May 10, 2000, for the purpose of

redesignating the Telluride, Colorado

and Pagosa Springs, Colorado areas from

nonattainment to attainment for

particulate matter with an aerodynamic

diameter less than or equal to a nominal

10 micrometers (PM10) under the 1987

standards. The Colorado Air Pollution

Control Division’s (Colorado) submittal,

among other things, documents that the

Telluride and Pagosa Springs areas have

attained the PM10 national ambient air

quality standards (NAAQS), requests

redesignation to attainment, and

includes maintenance plans for the

areas demonstrating maintenance of the

PM10 NAAQS for ten years. EPA is

approving these redesignation requests

and maintenance plans because

Colorado has met the applicable

requirements of the Clean Air Act

(CAA), as amended. Subsequent to this

approval, the Telluride and Pagosa

Springs areas will be designated

attainment for the PM10 NAAQS. This

action is being taken under sections 107,

110, and 175A of the Clean Air Act. In
