4.3 Adjustments to Confirmation Volumes Received by El Paso in the

Event of Supply Underperformance (Continued)


(i) Wellhead Nonperformance - El Paso shall reduce to

zero (0) a well's confirmed volume on Day 1 when

El Paso determines that such well is not producing.

The confirmation shall be restored after El Paso

determines that the well is producing.


(ii) Gathering System Underperformance - If supply

underperformance exists, gathering system monitoring

shall be performed by El Paso on a daily basis

utilizing the most current data available. El Paso

shall compare the most recent total actual

production to Operators' confirmed volumes for each

gathering system. When supply is expected to be

less than Operator confirmations and the shortfall

in receipts threatens the integrity of El Paso's

system, El Paso shall notify Operators promptly and

attempt to attain balancing in the affected

gathering system. After being notified by El Paso,

Operators may voluntarily reduce confirmed volumes

to the actual supply level. If Operators volunteer

collectively to reduce confirmations to the actual

supply level, thereby eliminating the supply

underperformance, no further action will be required

by El Paso. However, if Operators collectively fail

to eliminate the supply underperformance, then

performance factors shall be used by El Paso to

adjust the otherwise confirmed volumes as set forth



(1) Calculation of Performance Factors - El Paso

shall calculate performance factors applicable

to each Operator in each gathering system based

on a history of actual performance versus final

scheduled volumes. When there is no history on

which to calculate an Operator's performance

factor in a particular gathering system, such

Operator shall be included in the provisions

contained in this Section 4.3(c)(ii) with a

factor that does not indicate underperformance,

until such time as data become available.

El Paso shall use the three most current
