segments is rising and approaching a level or is expected to rise and

approach a level that is at or above the maximum pressure at which

Natural's facilities may be safely operated; or (5) at other times when

Natural is unable or anticipates it may not be able to fulfill its firm

contractual obligations or otherwise when necessary to maintain the overall

operational integrity of all or a portion of Natural's system. A Critical

Time may not be declared on all or a portion of the system for the purpose

of maintaining interruptible services on that portion of the system, but

interruptible gas may flow at times or on portions of the system when such

flow would not violate any operational control restrictions or provisions

of this Tariff. Natural shall notify Shippers on the Informational Postings

portion of its Interactive Website as to the reason(s) why a Critical Time

was declared.

 

(b) Notice of a Critical Time will be provided through

Electronic Notice Delivery consistent with GISB Standards as adopted in

Section 48 of these General Terms and Conditions and will be posted on the

Informational Postings portion of Natural's Interactive Website. Natural

will endeavor to provide and post the notice before 4:00 p.m. Central Time

or otherwise will endeavor to notify Shippers by 4:00 p.m. Central Time

that they should check the Informational Postings portion of Natural's

Interactive Website again at a specified later time to see whether a

Critical Time will be in effect for the next day. In addition, Natural must

attempt to give actual notice of a Critical Time via telefax or telephone

(provided a Shipper has given the numbers to Natural as required in Section

23) 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 the Critical Time

Balancing Service Charges will apply to over-receipts and under-deliveries

vis-a-vis confirmed nominations or to under-receipts and over-deliveries

vis-a-vis confirmed nominations. 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 Natural notifies Shippers via Natural's

Interactive Website that there is no longer a Critical Time.

 

12.6 EXEMPTIONS

assessed at a Receipt or Delivery Point where the variance between total

confirmed nominations and actual gas flows at that point is less than

Critical and Critical Times; provided, however, that this exemption shall

not apply to the extent specified in Section 6(d) of Rate Schedule IBS. In

addition, any Receipt or Delivery Point where the variance between the

total confirmed nominations and actual flows is less than 1,000 Dth per
