6.6 NOTICE OF CURTAILMENT - Transporter will post notices of curtailment on

its web site, and, if necessary, notify all affected shippers as soon as

practicable, and in a manner that is reasonable under existing

conditions, that a period of curtailment exists. Such notice will set

forth any limits on receipts or deliveries and the anticipated duration

of such curtailment period. Upon notice of curtailment, Shipper shall

adjust its receipts and/or deliveries of Gas as specified by Transporter

within the time period specified by Transporter. Shipper compliance

will be a change in Gas flow to the level specified by Transporter and

will be evidenced by the confirmation of a flow rate change by an

upstream or downstream Operator or the confirmation of the flow rate

change by Transporter.

6.7 CURTAILMENT PENALTIES - Failure of any Shipper to adjust its receipts

and/or deliveries within the time and in the manner specified by

Transporter will result in the imposition of curtailment penalties. All

Gas received or delivered for the account of Shipper after notification

of a curtailment under Subsection 6.6 that deviates from the quantities

set by Transporter in the notice of curtailment will be assessed a

penalty of Twenty-Five Dollars ($25.00) per Dt. The imposition of a

curtailment penalty will not relieve Shipper of its obligations to

resolve any imbalance created during a period of curtailment. Although

a notice of curtailment must result in an immediate change in Gas flow,

Transporter will not assess penalties unless notice of curtailment is

given at least twelve (12) hours before the curtailment is required.

Net penalty revenues will be applied to Transporter's Fuel, Lost and

Unaccounted for Gas account.

6.8 EMERGENCY PROCEDURES - Variations in the curtailment procedures set

forth in Subsection 6.5 may be permitted by Transporter when necessary

to respond to emergency situations (including environmental emergencies)

where supplemental deliveries are required to forestall injury to life

or property.
