12. DETERMINATION OF RECEIPTS AND DELIVERIES

12.1 General:

(a) Transporter shall accept GISB-approved predetermined

allocation methodology ("PDA") types from the

upstream or downstream custody transfer party who is

providing the point confirmation. The upstream or

downstream party providing the point confirmation

should submit the PDA to the allocating party after

or during confirmation and before start of gas day.

Only one PDA shall be applied per allocation period.

If there are no additions in nominations by a

Shipper at a point or other changes, the current PDA

will stay in effect as submitted until it is changed

pursuant to the foregoing procedures. The

allocating party should send back "confirmation" of

receipt of the PDA within 15 minutes. There is no

need to submit a PDA if Transporter has an OBA in

effect for a point.

(b) The same standard PDA should be available for use at

all points. The types of PDA are a list from which

two parties may agree as provided in Subsection

12.2(b). If the two parties cannot agree upon a

PDA, pro rata based upon confirmed nominations

should be used as the default method. The party

responsible for custody transfer (the party

performing the measurement function) should provide

the allocation.

the right to rely conclusively on the PDA for the

purposes of determining the daily quantities of gas

received or delivered by Transporter for the account

of Shipper at each point.
