GENERAL TERMS AND CONDITIONS

Requesting and Scheduling Service

11A.6. Routine Maintenance. Pipeline shall have the right

to interrupt, or discontinue service in whole or in part

on all or a portion of its system from time to time to

perform routine repair and maintenance on Pipeline's

system as necessary to maintain the operational

capability on Pipeline's system or to comply with

applicable regulatory requirements. Pipeline shall

exercise due diligence to schedule routine repair and

maintenance so as to minimize disruptions of service to

Customers and shall provide reasonable notice of the

same to Customers. In any such disruption, quantities

of gas deliverable under sales, storage, or

transportation rate schedules by Pipeline to Customer(s)

on a firm basis shall take priority over quantities of

gas deliverable by Pipeline to Customer on an

interruptible basis. So far as operating conditions

will permit, available natural gas shall be dispatched

in as equitable a manner as possible.

A. No later than each March 31, Pipeline will provide

a projection of routine maintenance scheduled for

the upcoming year, from April 1 through March 31,

which affects Pipeline's capacity at stated

Receipt and Delivery Points. Pipeline may in good

faith modify the projected schedule in any manner,

at any time during the Contract Year, and will

provide notice of any change in the schedule as

soon as possible after deciding to make such a

change. Pipeline will have no liability if actual

maintenance does not conform to the projected

annual schedule.

B. By the 20th of each month, Pipeline will provide a

schedule of maintenance for the next month which

affects Pipeline's capacity at stated Receipt and

Delivery Points, by posting it on the EBB. Such

notice will include an estimate of the duration of

the maintenance. Pipeline will have no liability

if it must modify the schedule or perform

additional unscheduled maintenance during the

month.
