General Terms and Conditions


11. System Operational Parameters


11.1 Notice of Changes in Operating Conditions. Transporter and

Shipper shall notify each other from time to time as necessary of

expected changes in the rates of delivery or receipt of gas, or in

the pressures or other operating conditions, and the reason for

such expected changes, to the end that the other party may be

prepared to meet them when they occur.


11.2 Tolerance Levels:

(a) It is recognized that receipts from Shipper and deliveries by

Transporter may vary above or below the quantities scheduled

on any day. Such variations shall be kept to the minimum

permitted by operating conditions and shall be balanced as

soon as practicable within the time provided in Shipper's

Service Agreement, but in no event shall exceed an allowable

daily variation of 10% of the scheduled quantities, and

provided further that the cumulative net variations during

any month above or below the quantities scheduled shall not

exceed 2.5% of the sum of the scheduled quantities for each

day of such month. Transporter and Shipper agree to correct

any cumulative net variations from scheduled quantities as

soon as practicable.


(b) Transporter will use the following operational measures to

assist shippers in keeping within allowed operating

tolerances: (i) contacting customers that are currently out

of daily balance to coordinate adjustments to their scheduled

quantities and actual flows; (ii) offsetting, to the extent

possible, packs and drafts on Transporter's system to

minimize impact on customers; (iii) assessing results after

the next intra-day scheduling cycle and contact customers

that remain out of balance; and (iv) using flow control

devices as necessary to maintain system integrity.


11.3 Critical Operating Procedures:


(a) Transporter may post a Critical Period Alert when one or more

of the following conditions have been triggered which

threaten the system integrity of its pipeline: (i) when a

system outage occurs; (ii) when extreme weather conditions

develop; (iii) when line pack exceeds (above or below)

operational tolerances; or (iv) when Transporter determines

that Shippers' deviations from scheduled quantities adversely

affect its ability to receive and deliver gas for its

Shippers. Shippers will be required to take immediate action

to bring their scheduled quantities and actual flows into
