limited by the ADWQ set forth in Exhibit A of Customer s AISS Service
Agreement, on a daily basis, provided that Caledonia shall not be obligated
under this AISS Rate schedule on any Day to deliver Gas in excess of the
working gas quantities then held in storage for Customer.
   
(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
quantities under this AISS Rate Schedule, regardless of the quantities set
forth in Customer s AISS Service Agreement, if such increase would degrade
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 AISS Rate Schedule.
Caledonia shall invoice Customer periodically for all taxes, if any,
attributable to the injection, storage or withdrawal of
Gas.
   
(f)     Service rights under an AISS Service Agreement may not be released.
(g)     Caledonia shall establish an account for each Customer using this
service which reflects the Advanced Interruptible Storage Balance.  Whenever
Caledonia receives AISS storage quantities from or delivers AISS storage
quantities to a Customer, Caledonia will adjust the Customer s account, as
appropriate, to reflect the new balance.
   
(h)     All Gas injected into storage for Customer s account under this AISS
Rate Schedule must be withdrawn by Customer s contract termination date,
provided that such final contract termination date shall be extended one Day
for each Day, during the 30 Days preceding Customer s final contract
termination date that Customer s AISS withdrawals are interrupted by
Caledonia.
   
3.     OVERRUN SERVICE
(a)     Provided injections and withdrawals can be accepted without impeding
Caledonia s ability to meet prior service obligations, a request by Customer
to make injections in excess of its ADIQ or withdrawals in excess of its ADWQ
may be submitted to Caledonia.  In the event that Customer makes such request,
Caledonia will confirm the request to the extent that (1) additional
flexibility exists during the time period of the request, and (2) Caledonia,
using reasonable discretion, can operationally accommodate the request.
   
   
(b)     Caledonia shall have the right to interrupt or not schedule all or
part of the overrun quantity nominated, as the operation of its facilities in
its reasonable judgment may require, subject to Sections 4.1 through 4.4 of
the General Terms and Conditions of this Tariff, in which event Caledonia
shall notify Customer.
