Item  5.          Other  Events.

          On  September  16,  2003, SEMCO Energy, Inc. (the "Company") announced
that the Company had entered into a definitive agreement to sell Alaska Pipeline
Company  ("APC")  to  Atlas  Pipeline  Partners, L.P. ("Atlas") for $95 Million.

          APC  owns  and operates the high-pressure gas pipelines that transport
gas  from  Alaska's  Cook  Inlet  gas  fields  to  ENSTAR  Natural Gas Company's
distribution  system  and  various  commercial customers of ENSTAR.  ENSTAR is a
division  of  SEMCO  ENERGY,  serving 112,000 customers in south-central Alaska,
including  Anchorage.  APC  has  no employees and ENSTAR is APC's only customer.
The  APC  system's present design delivery capacity is 410 million cubic feet of
gas per day, with an average throughput during 2002 of 132 million cubic feet of
gas  per  day.

          Consummation  of  the  sale  is  subject  to  a  number of conditions,
including  approval  of  the  Regulatory  Commission  of  Alaska and expiration,
without  adverse  action,  of  the  waiting  period  under the Hart-Scott-Rodino
Antitrust  Improvements  Act.

          As  part  of  the  sale,  the Company will enter into an operation and
maintenance  agreement with APC under which the Company will continue to operate
and maintain the pipeline for at least five years.  During the first three years
of the agreement, the Company will be paid $334,000 per month for such services;
thereafter,  the  Company's  fee  will  be based on its actual historic costs in
providing  the  services plus an inflation adjustment.  In addition, the parties
will enter into transportation agreements pursuant to which the Company will pay
a  reservation fee of $943,000 per month, plus $.075 per mcf of gas transported,
for  ten years for use of all of the pipeline's current transportation capacity.
