12. DETERMINATION OF RECEIPTS AND DELIVERIES

12.1 General:

(a) Transporter shall accept NAESB-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.

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.

(d) When the PDA is rank, swing or percentage, a new allocation

detail may be needed when a nomination changes.
