by the ADWQ set forth in Exhibit A of Customer s AILS Service
Agreement.
   
(ii)     return to Caledonia, on an interruptible basis, thermally equivalent
quantities of Gas, up to the Maximum Daily Injection Quantity (MDIQ), as
limited by the ADIQ set forth in Exhibit A of Customer s AILS Service

the working gas quantities loaned from storage for Customer, plus sufficient
quantities for Fuel Reimbursement.
   
(c)     Service provided under this Rate Schedule shall have the priority
specified in Sections 4.1 through 4.4 of the General Terms and Conditions of
this Tariff.
   
(d)     Customer shall not be permitted to increase its confirmed nomination

service to a Customer with equal or higher priority as set forth in Section 4
of the General Terms and Conditions.
   
(e)     Customer shall reimburse Caledonia for all other taxes associated with
the quantities held for Customer in storage under this AILS Rate Schedule.

balance.

Rate Schedule must be injected by Customer s contract termination date,
provided that such final contract termination date shall be extended one Day
