          - 40 CFR Part 52
          - [EPA-R05-OAR-2008-0240; FRL-8896-6]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

                        EPA is proposing to approve a site specific revision to the Minnesota sulfur dioxide (SO 2) State Implementation Plan (SIP) for the Rochester Public Utility's Cascade Creek Generating Facility (Cascade Creek), located in the city of Rochester, Olmsted County, Minnesota. On March 5, 2008, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain portions of a joint Title I/Title V document into the Minnesota SO 2                         SIP for the Cascade Creek facility. This SIP revision includes the addition of two new oil and gas fired turbines and modification of the starter engine on the No. 1 turbine. This SIP revision will show reduced emissions of SO 2                         from this facility and the SO 2                         National Ambient Air Quality Standards will be maintained in the area. Because the SO 2                         emission limits are being reduced, the air quality of Olmsted County will be protected.

# SUPPLEMENTARY INFORMATION:

                    In the Rules section of this                     **Federal Register**                    , EPA is approving the State's SIP submittal as a direct final rule without prior proposal because EPA views this as a noncontroversial submittal 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 rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. Any parties interested in commenting on this action should 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. For additional information, see the direct final rule which is located in the Rules section of this                     **Federal Register**                    .
