(D) Authorized Withdrawal Overrun Quantities


Upon request of Shipper, Trunkline may, but is not obligated

to, withdraw on any Gas Day Quantities of Natural Gas in

excess of Shipper's MDWQ under the Rate Schedule NNS-1,

NNS-2, FSS or ISS Service Agreement when, in Trunkline's sole

judgment, the capacity of its system will permit such

withdrawal, without impairing the ability of Trunkline to

meet its other obligations.


(E) The Quantities nominated by Shipper for injection into or

withdrawal from storage and Quantities injected into or

withdrawn from storage by Trunkline on behalf of Shipper

under Rate Schedule NNS-1 or NNS-2 shall be scheduled in the

following order:


(1) Firm service under Rate Schedule FSS, NNS-1 or NNS-2;


(2) Interruptible service in sequence starting with the

highest rate;


(3) Authorized Overrun Withdrawal and Injection Quantities

shall be scheduled as interruptible.


In the event a tie for capacity exists among Shippers,

Shipper's Storage Service Agreement request date will determine

the scheduling priority. For Shippers with the same request

date, Quantities shall be scheduled on a pro rata basis.


3.4 Scheduling Procedure for Parking Service


The Quantities nominated into interruptible parking service under

Rate Schedule GPS shall be scheduled in sequence starting with the

highest daily Parking rate. In the event of a tie, Quantities
