Liquefaction-Storage Gas Service (Continued)


6. DEFINITIONS (Continued)


6.6 Nominated Storage Volume. Shipper's Nominated Storage Volume shall

be the quantity of gas in Dth, up to Shipper's Storage Capacity Volume,

which Shipper nominates to have liquefied and stored in liquid form by

Transporter for Shipper's account and shall be provided to Transporter

in writing on or before April 1 of each year. In the event that Shipper

does not submit a storage volume nomination by April 1, Shipper's

Nominated Storage Volume for the Liquefaction Period shall be Shipper's

Storage Capacity Volume. Shipper upon ten (10) days written notice to

Transporter may elect to change its Nominated Storage Volume during the

liquefaction period. Such change shall not reduce the Nominated Storage

Volume below Shipper's Storage Capacity Balance at the time of election.




During a liquefaction period, Shipper is entitled to Nominate for

liquefaction and storage sufficient quantities of gas to fill Shipper's

Storage Capacity Volume. Such Nominations shall commence on April 1 and

shall consist of uniform daily quantities equal to 1/200th of Shipper's

Nominated Storage Volume (except for the last day of liquefaction) until

Shipper's Storage Capacity Balance is equal to Shipper's Nominated

Storage Volume. In addition, Transporter may schedule the liquefaction

period and rate of liquefaction to fit system operating conditions.


Transporter shall not be obligated to liquefy and store gas for

Shipper in excess of Shipper's Storage Capacity Volume.


The tender by Shipper to Transporter shall be made by Shipper

scheduling such tendered volumes on any day as transportation volumes

delivered under an executed Service Agreement for liquefaction and



If posted as available, Shipper may nominate gas for liquefaction

and storage during a Vaporization Period in replacement of gas vaporized

during such Vaporization Period; provided, however, the liquefaction of

such gas shall be at such times as may be agreed upon between

Transporter and Shipper. Such liquefaction will be in accordance with

the priority of service and curtailment policy delineated in Section 12

of the General Terms and Conditions.
