7. OPERATIONAL FLOW ORDER (OFO)

7.1 APPLICABILITY - An Operational Flow Order (OFO) is an order issued to

alleviate conditions, inter alia, which threaten or could threaten the

safe operations or system integrity of Transporter's system or to

maintain operations required to provide efficient and reliable firm

service. Whenever Transporter experiences these conditions, any

pertinent order will be referred to as an Operational Flow Order.

Transporter will determine, in its reasonable judgment, the

circumstances that will result in the issuance of an OFO.

Circumstances that may prompt an OFO cannot be quantified in advance

because the need to issue an OFO will depend on quantities of Gas

confirmed and scheduled, the point(s) where actual receipts or

deliveries deviate from confirmed and scheduled quantities, whether an

OBA governs the allocation at the point(s), and the relationship of

these individual factors to general System operations on any given Day.

Generally, an OFO may be issued if there is a significant decrease or

increase in line pressure or if a curtailment order fails to reduce gas

flow in the event there is insufficient capacity to handle all confirmed

and scheduled nominations.

OFOs will identify the situation to be addressed and will identify

specific actions to be taken by Shipper, stated in terms of an hourly

Gas flow level, and the probable duration of an OFO. Transporter will

provide periodic reports on Transporter's Internet Web Site (web site)

as to any changes in the condition that prompted the OFO and probable

duration of the OFO. OFOs affecting multiple Shippers on all or any

portion of Transporter's System will be posted on the web site. The OFO

will be posted within one (1) hour of its issuance and will be effective

within four (4) hours of issuance. To the extent an OFO is only

applicable to specific Shippers, Transporter may notify such Shippers by

telephone or facsimile, but the OFO will be effective as to such

Shippers when posted on Transporter's web site. Shipper must make a

contact person available on a twenty-four (24) hour basis to receive OFO

notices, and provide all necessary information to Transporter.

Transporter will use reasonable efforts to give actual notice to that

person, as time permits.
