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

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

shall notify Customer.
