8. NOMINATIONS, SCHEDULING, AND CURTAILMENT (Continued)

(i) The standard nominations timeline should be

as follows: 11:30 a.m. for nominations leaving control of

the nominating party; 11:45 a.m. for receipt of nominations

by MRT, noon for quick response; 3:30 p.m. for receipt of

completed confirmations by MRT from upstream and downstream

connected parties; 4:30 p.m. for receipt of scheduled

quantities by Customer and point operator (central clock

time on the day prior to flow). 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.

(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withdrawn from storage.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) herein shall be treated as an intraday nomination.

At least one (1) intraday nomination can be submitted four (4) hours

prior to gas flow. Unless MRT agrees otherwise, Customers and Pool

Operators may submit only one intraday nomination per contract for or

during a specific gas day.

(i) Intraday nominations can be used to request increases

or decreases in total flow, changes to receipt points, or changes

to delivery points of scheduled gas.
