Approval and Promulgation of Air Quality Implementation Plans; 
Colorado; Designation of Areas for Air Quality Planning Purposes, Lamar 
and Steamboat Springs

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is taking direct final action to approve a State 
Implementation Plan (SIP) revision submitted by the State of Colorado 
on July 31, 2002, for the purpose of redesignating the Lamar, Colorado 
and Steamboat 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 Governor's submittal, among other things, documents that the Lamar 
and Steamboat Springs areas have attained the PM10 national 
ambient air quality standards (NAAQS), requests redesignation to 
attainment and includes a maintenance plan for each of 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. Upon the effective date of this approval, the 
Lamar and Steamboat 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.
