TRANSPORTATION GENERAL TERMS AND CONDITIONS
                                (Continued)
   
                       (3)  Shipper is told by MIGC that the upstream shipper
did not have the gas or submit the nomination;
                       (4)  Shipper is told by MIGC that the downstream
confirming party did not conduct the confirmation;
                       (5)  Shipper is told by MIGC that the downstream
shipper did not have the market or submit the nomination.
   
       (b)    Ranking will be included in the list of data elements.  Rankings
 provided in a Shipper's Nominations shall be used to prioritize reductions to
 requested quantities when making reductions during the scheduling process
 when such prioritization is not in conflict with other provisions of this
 tariff.
   
       (c)  When used, Package ID will be supported for nominating,
 scheduling, confirming, allocating, and invoicing (sales and purchase), and
 not required for transportation invoicing.
   
       (d) Use of the Package ID is at the discretion of the Shipper, and if
 sent, will be accepted and processed by MIGC.
   
       (e)  The declaration to the affected parties of operational flow
 orders, critical periods, and/or critical notices will describe the
 conditions and the specific responses required from the affected parties.
   
       (f)  The key will be composed of:  shipper contract (Service
 Agreement), transaction type, upstream party, upstream contract (when
 applicable), receipt location (as applicable), downstream party, (as
 applicable) downstream contract (when applicable), delivery location (as
 applicable), package ID, upstream package ID (where mutually agreed),
 downstream package ID (where mutually agreed), capacity type indicator (where
 mutually agreed).  Upon receipt by MIGC from a shipper of a transaction whose
 key elements match those previously received by MIGC from the shipper, MIGC
 will then process the begin date/time and end date/time consistent with the
 intentions of the standard 1.3.7 and then process the rest of the
 transaction's data elements consistent with the applicable standards to
 determine the business results.  When data is not supplied (e.g., is not
 applicable, is not supported or is not mutually agreed upon) the pertinent
 portion of the key would be determined to be null.
   
       (g)  For current in-kind fuel reimbursement procedures, fuel rates will
 be made effective only at the beginning of the month.
