GENERAL TERMS AND CONDITIONS

20. SYSTEM OPERATION - (Continued)

(iii) TransColorado will interrupt interruptible services if

doing so will restore system flexibility prior to issuance of generally

applicable OFOs or curtailment of firm services. This step will be taken when

Shippers are failing to comply with previously issued OFOs or when

TransColorado cannot identify which Shippers are creating the problem.

H. In the event receipts in segments of TransColorado's system

exceed scheduled receipts so that high system pressures back off scheduled

receipt quantities, TransColorado may issue an OFO to all Shippers in the

affected segment of the system stating that a high pressure condition exists.

All such Shippers will be required to check their deliveries into receipt

points on the affected portion of the system. Those Shippers who are

delivering more than their scheduled volumes will have four (4) hours to make

needed adjustments, or enter the penalty situation. An OFO issued pursuant to

this Section 20.5H. will be canceled by TransColorado when the high pressure

condition described above has been corrected and the imbalances created by the

high pressure condition have been reasonably resolved.

I. In the event there is a need for TransColorado to

engage in routine and normal maintenance of the system, to undertake repairs

and replacements of lines of pipe, to schedule DOT compliance activities, to

install taps, to make pig runs, to test equipment, to check or change

compressor internals, or to engage in other similar actions affecting the

capacity of any portions of the system, TransColorado may issue OFO's pursuant

to this Section 20.5I, which will contain an estimate of the time, duration,

and impact of the activity. An event of force majeure may affect deliveries,

but not trigger the need for an OFO pursuant to this Section 20.5I. An order

issued pursuant to this Section 20.5I shall be canceled when such planned

maintenance or other activities have been completed.

J. Notice and posting shall include but not be limited to (i)

mandated specific actions, (ii) indication of voluntary actions, (iii)

identification of the parties subject to the OFO, (iv) the time the OFO will

become effective, (v) the estimated duration of the OFO, (vi) whether

TransColorado is overdelivered or underdelivered, (vii) whether actual net

receipts need to be equal to or greater than actual deliveries or actual

deliveries need to be equal to or greater than actual net receipts, (viii)

whether or not authorized overruns are acceptable and (ix) 24 hour contact

number for TransColorado during the duration of the OFO.
