GENERAL TERMS AND CONDITIONS

9. SCHEDULING, CURTAILMENT AND IMBALANCES (Cont'd)

9.7 Emergency Situations

An emergency situation shall include, but shall not be limited to,

a drop in delivery pressure to one or more Shippers which

jeopardizes service to such Shipper(s), storage withdrawals,

including Rate Schedule X-24, exceeding or being expected to exceed

1.275 MMDth for any day, equipment failure resulting in reduced

delivery capacity on one or more segments of WNG's system, and

actual or threatened periods of daily balancing or capacity

curtailment.

WNG encourages parties to enter into voluntary agreements under

which gas may be diverted from one Shipper to another in emergency

situations. WNG will not provide emergency gas supplies, divert

gas supplies, compensate parties whose gas may be diverted or bill

parties who may receive gas diverted from others absent a written

agreement with the affected parties. WNG shall not be liable for

damages to any party adversely affected as a result of this Article

9.7.

In the event of an emergency situation, WNG will provide assistance

to any Shipper on its system who desires to obtain additional gas

or capacity, or to provide gas or capacity. Such assistance may

include posting of data on its EBB regarding emergency gas supplies

available, requests to purchase emergency gas supplies, firm

capacity available for emergency use and firm capacity needed for

emergency use. WNG will also provide any other relevant

information which it has available regarding measurement, flow data

and pressures as requested by affected Shippers.
