The quick response by MRT will be an electronic message to those

parties submitting nominations electronically advising of receipt

of the nomination and of any errors in communication or missing

required data elements.


(ii) All nominations should be considered original

nominations and should be replaced to be changed. When a

nomination for a date range is received, each day within that

range is considered an original nomination. When a subsequent

nomination is received for one or more days within that range,

the previous nomination is superseded by the subsequent

nomination only to the extent of the days specified. The days

of the previous nomination outside the range of the subsequent

nomination are unaffected. Nominations have a prospective

effect only.


(iii) Nominations received after nomination deadline

should be scheduled after the nominations received before the

nomination deadline.


(iv) Incomplete or Late Nominations. A Customer's or

Pool Operator's failure to submit properly completed nominations

may result in gas not being transported, pooled, or injected or

withdrawn from storage. A Customer's or Pool Operator's failure

to submit a nomination by the applicable deadline may result in

delays for the requested service. Late nominations will not be

accepted if such acceptance would result in the curtailment of

gas previously scheduled, unless MRT and all affected parties

agree to the contrary.


(g) Intraday Nominations. Any nomination submitted after the

nomination deadline for the day of gas flow specified in

Section 8.1(f)(i)(A) herein shall be treated as an intraday

nomination. Unless MRT agrees otherwise, until April 1, 1999,

Customers and Pool Operators may submit only one intraday nomination

per contract for or during a standard nomination cycle (excluding

corrections of errors identified in the quick response). Thereafter,

for services that provide for intraday nominations and scheduling,

there will be no limitation as to the number of intraday nominations

(line items as per GISB Standard 1.2.1) which a Customer or Pool

Operator may submit at any one standard nomination cycle or in total

across all nomination cycles. An intraday nomination is effective

only for the day specified in the nomination, must be submitted at

least four (4) hours prior to the requested change in gas flow, and

remains in effect through the end of such day.
