6. CURTAILMENT (continued)


accordingly, curtailment would not be of any benefit to the

supply of Seller's systems.


(g) Seller will implement this curtailment plan throughout each

of Seller's systems to the fullest extent possible

consistent with the practical operation of the system,

giving due regard to such factors as system capacity and

where curtailable customers are located in relation to where

the gas is needed.


(h) An emergency exemption from curtailment will be provided for

all firm electric utility customers to the extent required to

avoid the shedding of firm electric load upon an attestation

by a utility to Seller that: (1) the utility faces an

emergency situation wherein it will be required to shed firm

electric load unless an exemption from curtailment is granted

in an amount which will avoid shedding of load; (2) the

utility has no alternate fuel capability; (3) the utility has

exhausted all purchased power opportunities; (4) the utility

has utilized all alternative sources of power; and (5) the

utility will accept reduced sales, as soon as possible

thereafter, to offset the volumes taken during the emergency

exemption from curtailment. Electric utilities served at

more than one location are permitted to divert their

entitlements between plants so long as they stay within their

total entitlements, where Seller determines that this can be

done consistently with prudent operation of its system.


(i) Any firm customer claiming an emergency need for supplemental

sales during curtailment to forestall irreparable injury to

life or property shall furnish Seller with full details of

the nature, cause, unavoidability and estimated duration of

the emergency. This information is to be given by telephone

or telegraph followed by immediate written notice to Seller

signed by an officer or responsible employee under oath.

Upon receipt of the initial notice Seller will make such

investigation as is reasonably possible under the

circumstances and, if gas is available, Seller will deliver
