8. OVERRUN SERVICE

8.1 Upon request of Shipper, Transporter may (but is not obligated to)

receive, transport, and deliver on any Day, quantities of Gas in

excess of Shipper's MDQ under the ITS Agreement when, in

Transporter's reasonable judgment, the Capacity and operating

capability of its System will permit such receipt, transportation

and delivery without impairing the ability of Transporter to meet

its other obligations ("Authorized Overrun Service"). Requests

for Authorized Overrun Service shall be subject to the Authorized

Overrun Service priorities set forth in the General Terms and

Conditions of this Tariff. Shipper may utilize Primary and

Secondary Receipt and Delivery Points in accordance with the

provisions of this tariff; however, such use may result in the

Shipper exceeding its Capacity rights (as specified by MDQ),

either by zone or in total, but not both. Utilization by Shipper

which exceeds its Capacity rights shall constitute Authorized

Overrun Service provided by Transporter and Shipper shall incur

Authorized Overrun Service Charges as a result of such use.

Shipper shall pay Transporter the maximum rate for Authorized

Overrun Service set forth in this Tariff unless otherwise agreed.

8.2 For any Overrun Service hereunder which is not authorized

("Unauthorized Overrun Service"), Shipper shall pay Transporter,

in addition to the Authorized Overrun Service Charge, an

Unauthorized Overrun Service Charge. Such Unauthorized Overrun

Service Charge shall equal the amount of Gas in Dth tendered to

Transporter or delivered to Shipper under an ITS Agreement, which

exceeds Shipper's Nomination on any Day under such ITS Agreement,

multiplied by two (2) times the daily index price for the Day on

which the Unauthorized Overrun occurred, as published in "Platt's

Gas Daily," under the "Midpoint" column, for the locations listed

below:
