GENERAL TERMS AND CONDITIONS

20. SYSTEM OPERATION

20.1 General.

A. TransColorado shall endeavor to maintain adequate pressure

throughout its system and to preserve the overall operational integrity of its

system; provided, however, that TransColorado shall not be obligated to buy or

sell gas or to install additional compression or otherwise modify its system

for these purposes. Operating personnel for Shippers and other entities that

are physically taking delivery of gas from TransColorado or tendering gas to

TransColorado shall cooperate with TransColorado in furtherance of this

Section. Each Shipper shall designate the e-mail, telephone and fax numbers

of one or more persons (but not more than two (2) primary and two (2) backup

persons) for TransColorado to contact on operating matters (including the

receipt of Operational Flow Orders and notices of a Critical Time consistent

with Section 20.5) at any time, on a 24-hour a day, 365-days a year basis.

Such contact persons must have adequate authority and expertise to deal with

such operating matters.

B. For the purpose of these General Terms and Conditions, the

overall operational integrity of TransColorado's system shall encompass the

integrity of the physical system and the preservation of physical assets and

their performance, the overall operating performance of the entire physical

system as an entity (or any portion thereof), and the maintenance (on a

reliable and operationally sound basis) of total system deliverability and the

quality of gas delivered.

20.2 Facility Control. TransColorado shall maintain actual physical

and operational control of all transmission and other facilities on its

system.

20.3 Operational Control Sequence. In the event TransColorado's

observations or projections indicate that a situation is or may be developing

in which adequate pressures may not be maintained or the overall operational

integrity of its system (or any portion thereof) could be threatened, or in

the event that such a situation actually occurs, TransColorado is authorized

by this Section to take action to alleviate this situation. In responding to

such a situation, TransColorado shall first apply the Advisory Actions

procedures of Section 20.4. If such measures are not sufficient in

TransColorado's judgment to address the situation fully, TransColorado shall

next employ the Critical Time procedures set out in Section 20.5. Finally,

TransColorado may take unilateral action as provided in Section 20.6. The

procedures set out in such provisions, and their sequencing, are intended to

be applied only to the extent any of the specific actions indicated, or such

sequencing, would be anticipated to alleviate the situation to be addressed.

In issuing Advisory Actions consistent with Section 20.4 or a Critical Time

consistent with Section 20.5, TransColorado shall describe the conditions and

the specific responses required from the affected parties.
