Clean Air Act Approval and Promulgation of PM10 State 
Implementation Plan for Colorado; Telluride; Revisions to the 
Maintenance Demonstration

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.


SUMMARY: EPA proposes to approve the State implementation plan (SIP) 
revisions for Telluride as submitted by the Colorado Governor with a 
letter dated April 22, 1996. EPA proposes that the April 22, 1996 
submittal now satisfies the State's April 21, 1994 commitment to adopt 
additional control measures in Telluride as necessary to demonstrate 
maintenance of the National Ambient Air Quality Standards (NAAQS) 
through December 31, 1997, for particulate matter with an aerodynamic 
diameter less than or equal to a nominal 10 micrometers (PM10). 
Based on that commitment, EPA conditionally approved the quantitative 
milestones element of the Telluride PM10 SIP on September 19, 
1994. The April 22, 1996 submittal incorporates new street sanding 
requirements and demonstrates maintenance of the standard through 1997. 
EPA proposes to approve these revisions, and therefore, convert its 
September 19, 1994 conditional approval to a full approval.
    In the Final Rules Section of this Federal Register, EPA is 
approving the State's SIP revisions as a direct final rule without 
prior proposal because the Agency views this as a noncontroversial 
revision and anticipates no adverse comments. A detailed rationale for 
EPA's actions is set forth in the direct final rule. If no adverse 
comments are received in response to this proposed rule, no further 
activity is contemplated and the direct final rule will become 
effective. If EPA receives adverse comments, the direct final rule will 
be withdrawn and all public comments received will be addressed in a 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 on this document should do so at this time.

DATES: Comments on this proposed rule must be received in writing by 
November 4, 1996.

ADDRESSES: Written comments on this action should be addressed to 
Richard R. Long, 8P2-A, at the EPA Regional Office listed below. Copies 
of the State's submittal and documents relevant to this proposed rule 
are available for inspection during normal business hours at the
