to have its scheduling nomination accepted and

scheduled by Richfield to the extent interruptible

capacity is available.

Within each service category provided in (a)

through (c) above, a Customer may, through

telephone, telefacsimile, or electronic means,

provide a ranking of individual Points of Delivery

within a Customer's Agreement in the event the

entirety of the Customer nomination cannot be

scheduled. Ranking will be included in the list of

data. Richfield shall use Customer provided

rankings when making reductions during the

scheduling process when this does not conflict with

tariff-based rules.

4.5 Service under any Richfield Rate Schedule shall be

subject to interruption under the terms of Customer's

Service Agreements under Rate Schedules of any connected

pipeline or pipelines. Any limitations imposed by such

connected pipeline Rate Schedules shall have precedence

over Customer's rights to service herein.

4.6 In the event that any connecting pipeline is required to

allocate capacity on its system, service under any Rate

Schedule may be constrained by the allocation of capacity

under the Customer's applicable Rate Schedule on the

connecting pipeline.

4.7 Operational Flow Orders. An "Operational Flow Order"

("OFO") is an order issued by Richfield to alleviate

conditions which threaten or could threaten the safe

operation or system integrity of Richfield's system or to

maintain operations required to provide efficient and

reliable firm service. Whenever Richfield experiences

these conditions, any pertinent order shall be referred

to as an OFO. The declaration to the affected parties of

OFOs, critical periods, and/or critical notices shall

describe the conditions and the specific responses

required from the affected parties. In the event that

Richfield receives notice of an OFO from a downstream

transporter or Richfield is required to establish an OFO

for a portion of its own system, Richfield will notify

Customer of the date and the time that the OFO will go

into effect, the specific action(s) that need to be taken

by Customer, and the deadline for such actions(s).

Customer shall then either (i) make a nomination which

upon confirmation and scheduling, would be satisfactory

to Richfield, or (ii) take other appropriate action(s)

satisfactory to Richfield. If Customer does not take

such action in accordance with the deadline established

in the OFO, Richfield shall have the right to take such

action as it deems necessary to cure the circumstance

giving rise to the OFO.
