ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[MN48-01-7273b; FRL-6415-3]


Approval and Promulgation of State Implementation Plan; Minnesota

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: We are proposing to approve a December 31, 1998, request from 
the Minnesota Pollution Control Agency for new air pollution control 
requirements for the Minnesota sulfur dioxide (SO2) State 
Implementation Plan (SIP) for Marathon Ashland Petroleum LLC 
(Marathon). These requirements were submitted in the form of an 
Administrative Order (Order) and include revisions associated with the 
addition of a new stack, revised emission limits for numerous sources 
and other changes. The revisions result in an overall decrease in 
allowable SO2 emissions from the facility. The new 
requirements have been evaluated through a computerized modeling 
analysis and have shown that they will attain and maintain the National 
Ambient Air Quality Standard (NAAQS) for SO2.
    In the final rules section of the Federal Register, EPA is 
approving the State's submittal as a direct final rule without prior 
proposal because EPA views this action as a noncontroversial action and 
anticipates no relevant adverse comments. A detailed rationale for the 
approval is set forth in the direct final rule. If no relevant adverse 
comments are received in response to this rule, no further activity is 
contemplated, and the direct final rule will become effective. If EPA 
receives relevant adverse comments, the direct final rule with be 
withdrawn, and all public comments received during the 30-day comment 
period set forth below will be addressd in a subsequent final rule 
based on this proposed rule. The EPA will not institute a second 
comment period on this action. Any parties interested in commenting on 
this action should do so at this time.

DATES: We must receive comments by September 15, 1999.

ADDRESSES: Written comments should be sent to: Carlton T. Nash, Chief, 
Regulation Development Section, Air Programs Branch, (AR-18J), U.S. 
Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, 
Chicago, Illinois, 60604.
