3.1 New interruptible transportation services of Transporter

under this Rate Schedule ITS shall have priority for system capacity

subordinate to Transporter's firm sales, firm transportation and

existing interruptible sales and transportation, but equal to

Transporter's new interruptible sales. Service hereunder may be

curtailed pursuant to the provisions of Section 3.2 hereof due to

capacity constraints but shall not be subject to supply-related

curtailments under Section 8 of the General Terms and Conditions of

Transporter's Second Revised Volume No. 1 Tariff. If at any time

existing conditions require the utilization of capacity then being

devoted to transportation services in order to maintain the integrity

of Transporter's system or any part thereof, Transporter may curtail

service hereunder pursuant to the provisions of Section 3.2 hereof.


3.2(a) If nominated or scheduled volumes at the Receipt or

Delivery Point(s) under Interruptible Transportation Service Agreements

on any day exceed Transporter's available capacity on that day to

provide such services, Transporter shall allocate available capacity

among Shippers in accordance with the following order of priority:


(i) Transporter shall first allocate capacity to

interruptible transportation customers under arrangements

already in effect as of the date this Rate Schedule ITS first

becomes effective based upon the date of their transportation

contract with Transporter such that the Shipper with the

oldest contract shall receive highest priority. If

curtailment is necessary within this category, such

curtailment shall commence with the Shipper who has the most

recently dated contract and such Shipper shall be fully

curtailed before any other Shipper, then the Shipper with the

next most recently dated contract, and so on.
