3.8 Operational Arrangements


It is essential that Transporter maintain operational and physical control of its pipeline

system to ensure the integrity of that system and to assure that necessary Transportation

Service is provided to Transporter's Shippers during a contract year. From time to time it may

be necessary for the Transporter to enter into operational arrangements with other pipeline

companies, local distribution companies, Shippers under either Transporter's FERC Gas Tariff,

Original Volumes No. 2 or Second Revised Volume No. 1, or other persons to maintain such

operational and physical control of the pipeline system. Examples of such operational

arrangements include, but are not limited to, operational balancing agreements with pipeline

companies, local distribution companies, Shippers or other operators of facilities

interconnecting with Transporter's system, agreements necessary to effectuate construction and

maintenance on the system, agreements necessary to continue service during unplanned outages or

emergency situations, and operational purchases and sales of gas pursuant to Section 3.8(A)

herein. As necessary, Transporter shall enter into such operational arrangements. These

operational arrangements shall reflect the constraints on the Transporter's pipeline system that

exist from time to time. The intended effect of such operational arrangements on Transporter's

Shippers shall be to ensure the integrity of Transporter's pipeline system to minimize any
