16.5 Relief From Interruptions of Firm Transportation Service in Emergency Situations.

(a) Transporter shall adjust interruptions made pursuant to this Section to the extent necessary to

respond to emergency situations. An emergency situation exists when irreparable injury to life or property

(including minimum plant protection requirements) will occur if natural gas transportation service is not

rendered to a Shipper under Transporter's firm transportation service agreements. Emergency exemptions from

interruption procedures or orders under this Section may be requested by a Shipper of firm transportation

services when supplemental deliveries in excess of its pro rata interruption level are required to prevent

irreparable injury to life or property, and such Shipper (1) has arranged to use all alternate sources of

supply and capacity available, including other pipeline capacity capable of operationally serving the affected

area of interruption, recallable released capacity, and alternate fuels, for the period involved, and (2) has

interrupted and will continue to interrupt service to its interruptible, off-system sales and low priority

shippers during the emergency.

(b) Such request shall be submitted by the Shipper to Transporter by telephonic or facsimile

transmission, and shall be confirmed in writing, within 24 hours of the request, including a sworn, notarized

statement attesting (1) to the details of the emergency; (2) its estimated length; (3) that Shipper has

unsuccessfully attempted to obtain capacity from other sources, including capacity release and assignment; (4)

that all sources of gas supply and capacity, including that available from other pipelines capable of

operationally serving the affected area of interruption are being used; (5) that interruptible services are

unavailable; (6) that no alternate fuel can be used to avoid the emergency; and (7) that it has interrupted

service to its interruptible shippers, off-system sales and other low priority shippers and will continue to

do so during the emergency.
