13. DETERMINATION OF RECEIPTS AND DELIVERIES

13.1 Determination of Receipts. Shipper’s allocated receipts shall be

the scheduled quantities at the Receipt Point. Any imbalances

resulting from a variation between the aggregate of Shipper’s

allocated receipts and measured flow at an interconnection, which

are not resolved pursuant to Section 13.5, shall be managed under

an OBA between such interconnecting party and Pipeline. Shipper

shall be responsible for any imbalances that it creates on any

upstream pipeline.

13.2 Determination of Deliveries. Shipper’s allocated deliveries

shall be determined by either a PDA methodology or OBA at the

Delivery Point.

(a) If no OBA exists for a Delivery Point, the Delivery Point

Operator shall, within 48 hours after the Gas Day when such

PDA will be effective, provide Pipeline (or Shipper shall

cause the interconnecting Delivery Point Operator to

provide Pipeline, if applicable) with a PDA at the Delivery

Point(s) where Pipeline tenders gas to such Delivery Point

Operator. The Delivery Point Operator shall select one of

the following forms of PDA:

(1) Swing PDA;

(2) Percentage PDA;

(3) Pro Rata PDA;

(4) Ranked PDA; or

(5) OPV PDA.

(b) If a Swing PDA is selected, the Shipper whose contract is

designated as the swing must confirm the swing election

prior to the PDA being accepted by Pipeline. If the swing

contract is terminated or is in default, Point Operator

must designate another contract as the swing or elect

another PDA methodology. If no such designation or

election is made, Pipeline shall use the Pro Rata PDA

methodology.
