18. DETERMINATION OF DELIVERIES AND RECEIPTS, ALLOWABLE DAILY DISPATCHING VARIATIONS, OVERRUN

CHARGES AND PENALTIES

18.1 (a) Determination of Deliveries at Non-Pipeline Interconnects

(i) Each delivery point operator which takes gas quantities from Seller's

system shall, in accordance with the nomination and ranking deadlines, set

forth in Section 28.1 of the General Terms and Conditions, provide Seller

(or Buyer shall cause the interconnecting delivery point operator to

provide Seller, if applicable) via 1Line with a predetermined allocation

(PDA) at the point(s) of delivery where Seller tenders gas to such

delivery point operator by 10:30 a.m. CCT on the day following gas flow.

Seller, in its sole judgment, may waive such deadline, on a non-

discriminatory basis. The delivery point operator shall designate which

services are to "take the swing" on any day that measured quantities are

greater than or less than the scheduled quantities, including (1)

identification of the "swing supplier(s)" under transportation services,

(2) the priority ranking of "swing" storage services (scheduled or

unscheduled), and (3) the services to which any overruns under this

Section 18 will be allocated. The PDAs provided hereunder by such

delivery point operator to Seller shall include a numeric rank and

quantity (limit value) in accordance with Section 18.1(a)(ii) below, and

shall include a ranking of all available firm services (scheduled or

unscheduled) to which measured quantities shall be allocated so as to

eliminate or minimize any daily unauthorized overruns under this section.
