GENERAL TERMS AND CONDITIONS

(Continued)

6. OPERATIONAL FLOW ORDERS (OFOs)

6.1 Trunkline will have the right to issue an OFO to any Shipper, OBA

Party or TABS-1 Party when, in Trunkline's sole judgment, it is

required to alleviate conditions which threaten system integrity,

safety or service or to ensure compliance with the provisions

contained in this Tariff. During conditions which threaten system

integrity, safety or service, an OFO will not be issued to protect

interruptible service.

Examples of conditions which may cause OFOs to be issued

include, but are not limited to:

(A) Actual receipts exceeding scheduled receipts causing high

pressure to back off scheduled receipts;

(B) Unscheduled pipeline maintenance and repairs affecting

capacity;

service where such non-compliance threatens Trunkline's

system integrity; and

(D) When the applicable Tolerance Level has not been exceeded by

an individual Shipper, OBA Party or TABS-1 Party, but on a

system-wide basis pipeline operations require tighter

Tolerance Levels.

6.2 An OFO may be issued on a contract basis or on all or a portion of

the system. Ordinarily, an OFO issued by 10:00 a.m. on a Gas Day

will be effective at 8:00 a.m. the following Gas Day. When

extreme conditions exist, three hours notice, or lesser notice if

necessary, may be given. An OFO may be issued for a specific

period of time or until further notice is given.

6.3 (A) Any Shipper, OBA Party or TABS-1 Party subject to an OFO

will be deemed to be in compliance with the OFO if its

actual Quantities do not vary from the Quantities specified

in the OFO by more than the tolerance level stated in the

OFO, which shall not be less than two percent (2%). If the

actual Quantities vary from the Quantities specified in the

OFO by more than the tolerance level, the excess variance

shall be subject to a $25 per Dt penalty; provided, however,

in no event will this penalty apply until Shipper, OBA

Party, or
