20. SYSTEM OPERATION - (Continued)


(g) In issuing OFOs to correct problems with either too much

gas or insufficient gas being received vis-…-vis deliveries, TransColorado

will generally follow the following sequence, to the extent there is

sufficient time:


(i) TransColorado will require all Shippers out of

balance to the detriment of the system to balance their Agreements.


(ii) TransColorado will seek voluntary action from

Shippers, subject to the Shipper and TransColorado negotiating adequate



(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



(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 20.5(h). 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 20.5(i), 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 20.5(i). An order issued pursuant to this

Section 20.5(i) shall be canceled when such planned maintenance or other

activities have been completed.
