Approval and Promulgation of Air Quality Implementation Plan; 
Colorado; Designation of Area for Air Quality Planning Purposes, Aspen

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the Governor of the State of Colorado on November 
9, 2001, for the purpose of redesignating

[[Page 26249]]

the Aspen, Colorado area 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 
Governor's submittal, among other things, documents that the Aspen area 
has attained the PM10 national ambient air quality standards 
(NAAQS), requests redesignation to attainment, and includes a 
maintenance plan for the area demonstrating maintenance of the 
PM10 NAAQS for 10 years. EPA is proposing to approve this 
redesignation request and maintenance plan because Colorado has met the 
applicable requirements of the Clean Air Act (CAA), as amended. 
Subsequent to this approval, the Aspen area would be designated 
attainment for the PM10 NAAQS. This action is being taken 
under sections 107, 110, and 175A 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 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 June 16, 2003.

ADDRESSES: Written comments may be mailed to Richard R. Long, Director, 
Air and Radiation Program, Mailcode 8P-AR, 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 Colorado Department of Public Health and Environment, 
Air Quality Control Commission, 4300 Cherry Creek Drive South, Denver, 
Colorado 80246-1530.

Final action of the same title which is located in the Rules and
