Approval and Promulgation of Air Quality Implementation Plans; 
Colorado; Designation of Areas for Air Quality Planning Purposes

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 
September 22, 1997, for the purpose of establishing a redesignation for 
the Canon City area from nonattainment to attainment for particulate 
matter with an aerodynamic diameter less than or equal to a nominal 10 
microns (PM10) under the 1987 standards. The Colorado Air 
Pollution Control Division's (Colorado) submittal, among other things, 
documents that the Canon City 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 ten years. 
In the ``Rules and Regulations'' section of this Federal Register, EPA 
is approving the State's submittal as a direct final rule without prior 
proposal because the Agency views this as a noncontroversial SIP 
revision and redesignation 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.

DATES: Comments must be received in writing on or before June 29, 2000.

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 500, 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 500, 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 Pollution Control Division, 4300 Cherry Creek Drive South, Denver,

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