Start Preamble

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 Start Printed Page 26249the 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.
