6.9 Curtailment and Interruption

Seller shall have the right to curtail, interrupt or

discontinue service in whole or in part on its system from

time to time and at any time, under the following conditions

and in the following manner:

(a) Operating or Remedial Curtailment or Interruption may be

ordered by Seller at any time if in Seller's judgment

capacity or operating conditions so require or it is

desirable or necessary to make modifications, repairs or

operating changes, the conduct of which will be affected

thereby, upon such notice as is reasonable under the

circumstances and in the following order, to the extent

practicable: (1) interruptible storage service shall be

curtailed commencing with service that at the time notice

was given was being charged at a rate that is less than

the maximum rate of Seller then in effect under this

tariff in sequence starting with the rate least proximate

to the maximum rate and then with service which was

initially provided most proximate to the date notice is

given by the Seller of the particular curtailment or

interruption; next in order shall be all other storage

service in sequence starting with service which was

initially provided most proximate to the date notice is

given by Seller of the particular curtailment or

interruption. In the event Buyer is receiving

service at less than the applicable maximum rate and

Seller determines that interruption or curtailment of

service is required, Seller shall notify Buyer that

Buyer will be required to pay the applicable maximum

rate in order to avoid interruption or curtailment of

service to the extent that any interruptible service

is available as determined by Seller. Buyer's

election to pay the applicable maximum rate shall be

a one-time election effective during such periods of

interruption or curtailment regardless of duration.

Buyer's election shall be made at the time Seller and

Buyer agree to such discounted rate. (2) Firm storage

service shall be curtailed last on a pro-rated basis.

Such proration shall be based on Seller's maximum firm

contractual obligations to provide firm service.
