5.2 NOMINATION DEADLINES -

a. The Timely Nomination Cycle - The standard nominations timeline is

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

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

Transporter (including from Title Transfer Tracking Service

Providers (TTTSPs)); noon to send Quick Response; 3:30 p.m. for

receipt of completed confirmations by Transporter from upstream

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

scheduled quantities by Shipper and point Operator (Central Clock

Time on the Day prior to flow).

b. Intraday Nominations - A Shipper may submit and Transporter will

accept Intraday nominations, provided: (i) such nominations are

within Shipper's total MDRQ-Mainline, MDRQ-Expansion, MDVQ-

Mainline and MDVQ-Expansion or MDTQ-Mainline and MDTQ-Expansion

and (ii) such nominations can be confirmed. Intraday Nominations

may be used to start service, to request increases or decreases in

nominated quantities, to nominate new supply or market, or to

reflect changes in the specified Receipt and Delivery Points.

Intraday Nominations will be effective only for a single Gas Day,

and, therefore, will not remain in effect for prospective Days.

To the extent a Shipper submits an Intraday Nomination (including

nominations received after the standard nomination deadline) which

specifies an effective term of longer than one Gas Day,

Transporter will make the nomination effective only for the first

Gas Day of the specified effective period.

Intraday Nominations may be submitted to Transporter at any time,

and will be scheduled in accordance with Section 6.3 of this FERC

Gas Tariff. Except as provided in iii. below, Intraday Nominations

for firm transportation services will be given priority over

scheduled and flowing interruptible transportation services.
