effective date, and then, if two or more shippers have

the same request for service date, the service shall be

prorated based on the requested daily volumes. Firm

of any interruption, or as much notice as is possible, in

rates being paid by other shippers, the quantities being

transported at such rates and the estimated reduced

quantities of gas that can be transported.


9.4 In the event gas supply shortages at Delivery points

occur due to capacity constraints, such shortages shall

be handled under the following procedure:


(a) If any Shipper of Transporter experiences or

anticipates a supply emergency which could cause

injury to essential human needs and minimum plant

protection, such Shipper shall utilize to fullest

extent possible all of Shipper's existing gas supply

arrangements, including storage inventories and

available self-help measures to alleviate such

emergency prior to requesting assistance from

Transporter and other Shippers pursuant to this



(b) Any assistance required to resolve a supply

emergency will be based, to the maximum extent

possible, on voluntary, market-based arrangements

involving a sale of gas by a willing seller to the

Shipper experiencing the emergency shortage, at a

rate to be negotiated by the parties to this sale.

Such transaction could involve the pre-arrangement

of portfolios of divertable supply, or short-term

arrangements through the use of Transporter's

electronic bulletin board or any other arrangement

acceptable to the parties to this sale.
