6.  AUTHORIZED OVERRUN SERVICE
   
    Upon request of Shipper, MIGC, at its reasonable discretion, not to be
exercised in an unduly discriminatory manner or otherwise in a manner
inconsistent with the regulations of the FERC, may receive, transport
and deliver natural gas in excess of Shipper's Transportation Contract
Demand specified in the executed Transportation Service Agreement
provided such scheduling does not affect those shippers with superior
priority of service rights.  Authorized Overrun Service under Rate
Schedule FTS-1 shall have equivalent priority to Interruptible 
Transportation Service.
   
    Transportation and delivery of natural gas shall exceed Shipper's
Transportation Contract Demand when the sum of the nominations through
or within a specific Segment, including all forward and backward haul
segmentation nominations and including Releasing and Replacement
Shipper nominations, exceed the Transportation Contract Demand.
   
    Volumes transported in excess of the Maximum Daily Quantity at a
specific point are considered to be secondary nominations but are not 
considered to be overrun volumes unless such nominations result in the
transportation of a volume over a specific transportation segment in
excess of the Transportation Contract Demand.
   
    If MIGC elects to transport said excess gas, Shipper shall pay MIGC for
each MMBtu of gas in excess of Shipper's Transportation Contract Demand
delivered to MIGC by Shipper or for Shipper's account during the month
the charges set forth below:
   
    (a)   A unit amount in dollars per MMBtu equivalent to the "Maximum
Rate" applicable for service under MIGC's Rate Schedule ITS-1, as such rate
is in effect and reflected from time to time on Sheet No. 4 of this Second
Revised Volume No. 1 Tariff, or superseding tariff; and
   
    (b)   The fuel reimbursement charge provided for in Section 7 of this
Rate Schedule.
