20. SYSTEM OPERATION - (Continued)


(b) TransColorado shall advise Shippers on its system if it

is declaring a Critical Time, as described in Section 20.5(a) above, and

shall specify the nature of the situation creating the Critical Time.


(c) TransColorado may issue OFOs as described in this Section

20.5 during a Critical Time.


(d) All quantities tendered on a net contract basis to

TransColorado and/or taken by Shipper on a daily basis in violation of

TransColorado's OFOs issued during a Critical Time shall constitute

unauthorized receipts or deliveries for which a charge of $25 per Dth plus

the San Juan Basin spot price of gas, as determined in Section 12.3 of

these General Terms and Conditions, for the days the OFO is in place shall

be assessed and the resulting imbalance will be reduced to zero.


(e) Notice of a Critical Time will be posted on the DART

system, and will be the first information item shown on the bulletin board

feature of DART. TransColorado will endeavor to post the notice on DART

before 4:00 p.m. CCT or otherwise will endeavor to notify Shippers via

DART by 4:00 p.m. CCT that they should check DART again at a specified

later time to see whether a Critical Time will be in effect for the next

day. TransColorado must attempt to give actual notice of a Critical Time

via e-mail, fax or telephone (provided a Shipper has given the numbers to

TransColorado as required in this Section) at least four (4) hours prior

to the start of the day before a Critical Time will be effective as to a

Shipper. Such notice shall specify the anticipated duration of the

Critical Time and whether other charges will apply to over-receipts and

under-deliveries vis-…-vis confirmed nominations or to under-receipts and

over-deliveries vis-…-vis confirmed nominations. If reasonably possible,

a Critical Time will be effective at the start of a day and will continue

until the end of the day and through the end of successive days until

TransColorado notifies Shippers via DART that there is no longer a

Critical Time.


(f) In the event that, in TransColorado's judgment, the

Advisory Actions under Section 20.4 are not sufficient to alleviate

conditions, inter alia, which threaten or could threaten the safe

operations or system integrity of TransColorado's system or to maintain

operations required to provide efficient and reliable firm service,

TransColorado is authorized to issue OFOs.
