Original Sheet No. 100 Original Sheet No. 100

An OFO will go into effect when a notice is given as follows: (i) For

Level 1 OFO notices: at least 24 hours prior to the beginning of the Gas

Day in which the notice goes into effect; (ii) For Level 2 OFO notices:

at least 4 hours prior to the beginning of the gas Day in which the

notice goes into effect; (iii) for Level 3 OFO notices: at least 4 hours

prior to the effective time of the OFO notice if a Level 1 or Level 2 OFO

is already in effect as provided above. If a Level 1 or Level 2 OFO is

not already in effect, then COMPANY must give SHIPPERS at least 20 hours

notice prior to the effective time of the notice to implement a Level 3

OFO. Such notice shall specify the beginning time of the operational

flow order and such operational flow order shall remain in effect until

cancelled by COMPANY. In the notice COMPANY shall specify the reason for

the operational order and the expected conditions that would cause

release of the order.

(b) To determine an event which may give rise to an OFO under this section,

COMPANY shall evaluate the current status of the system, including, but not

limited to, the line inventory, line pressures, equipment availability and

outages, the current imbalance status of the system, the month to date

imbalance status of the system, and the direction of change for any of

these criteria. COMPANY shall then evaluate the forecasted demand and

available capacity on the system based on these factors and the weather

forecast for areas across the system and any other factors which could

influence the level of usage or flow on the system, such as potential loss

of supply or market. Based on an evaluation of current and forecasted

system conditions, COMPANY shall post by 1:00 p.m. (CCT) each Gas Day the

operating condition for the current Gas Day and the projected operating

conditions, the likelihood of implementing an OFO under this section, and,

if a likelihood exists, the criteria that will be monitored for the

succeeding four Gas Days. Such operating conditions will be posted as

Normal, Level 1, Level 2, or Level 3. Normal Mode shall be implemented

when system conditions do not warrant a correction in flow, and when no

known threat to system conditions exists. A Level 1 OFO shall be

implemented when system conditions warrant a correction in flow because a

threat to system conditions exists such that daily entitlements may be

impaired. A Level 2 OFO shall be implemented when system conditions

warrant a prompt correction in flow because an imminent threat to system

conditions exists such that daily entitlements may be impaired. A Level 3

OFO shall be implemented when system conditions warrant an immediate

correction to flow because an event has occurred or is occurring that

jeopardizes system conditions such that daily entitlements may be impaired.

Under a Level 3 OFO, an event that jeopardizes system conditions shall be

considered to be either (i) any mechanical or pipeline failure on the

System upstream of a Delivery Point; or (ii) when a Level 2 OFO has been in

a place and System conditions continue to deteriorate.
