ACTION: Notice of proposed rulemaking. ----------------------------------------------------------------------- SUMMARY: In this document, the EPA is proposing approval of the State implementation plan (SIP) and SIP revisions submitted by the State of Colorado for the purpose of bringing about the attainment of the national ambient air quality standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10) in Aspen, Colorado. In the final rules Section of this Federal Register, the EPA is approving the State's SIP submittals as a direct final rule without prior proposal because the Agency views these submittals as noncontroversial and anticipates no adverse comments. A detailed rationale for the approval 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 in relation to this rule. If the EPA receives adverse comments, then the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on this document. Any parties interested in commenting on this document should do so at this time. DATES: Comments on this proposed action must be received in writing by October 14, 1994. ADDRESSES: Written comments should be addressed to Vicki Stamper, 8ART- AP, at the EPA Regional Office listed below.
