Item 5.  Other Events.

     On August 13, 1997, the Company, through a new subsidiary, acquired the 
assets and business of Michigan-based Sub-Surface Construction Co. 
("Sub-Surface") for $15.4 million in cash plus the assumption of certain 
liabilities.  Sub-Surface primarily constructed underground natural gas 
distribution pipelines, service lines and associated facilities.  Through the 
Company's new subsidiary, SEMCO Energy Construction Co. ("SEMCO Construction"), 
the Company now provides these construction services, which are strongly 
related to the Company's core energy business expertise.
     Sub-Surface was a privately held construction company headquartered in 
Comstock Park, Michigan, and owned by Stewart Kniff.  Sub-Surface operated five 
facilities in Michigan and employed at the peak of the construction season 
nearly 450 employees, many of whom were union field employees.  Sub-Surface had 
annual revenues of approximately $33 million, and had a long relationship with 
natural gas distribution companies throughout Michigan.
     SEMCO Construction has taken over Sub-Surface's business with essentially 
the same employees and will operate under the Sub-Surface name.  SEMCO 
Construction intends to continue Sub-Surface's high-quality construction 
services to natural gas distribution companies.  These services include 
installation of new distribution pipelines, mains and service lines to deliver 
natural gas as new customers demand service.  SEMCO Construction will also 
continue significant maintenance and replacement services for existing gas 
mains and service lines.
     The Company hopes to grow this business in Michigan and surrounding 
states.  Infrastructure work for electric, telephone, and cable services is 
a possible extension of the business.
