          - 40 CFR Parts 52 and 81
          - [CO-001-0058b, CO-001-0059b; FRL-6989-2]

# 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                               ( print page 32595)                            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.
