7.7 Predetermined Allocations - Receipts


(a) A receipt point operator or Pool Operator, depending on

whether the tender of gas will be at a physical receipt point or from

a pool, will be required to provide to MRT a "predetermined

allocation (PDA) methodology for the gas to be received. The PDA

methodologies which may be agreed upon in accordance with GISB

Standards include: ranked, pro rata (weighted), percentage and

swing. The PDA methodology provided will be utilized by MRT for the

allocation of receipts. MRT shall be entitled to rely conclusively

on the PDA methodology. Entities affected by the allocation of gas

quantities shall be entitled to know the allocation methodology

utilized, except that MRT shall keep confidential the names of the

other entities involved unless otherwise agreed by the affected

parties. MRT shall provide daily operational allocations within one

(1) business day after the day of gas flow as set forth in Section

10.1 of these General Terms and Conditions. MRT may use scheduled

quantities as the basis for such reports if such information is the

best information available.


(b) Two welded parties should agree on who submits PDA

methodology and who allocates at the point before gas flows

("allocating party").


(c) There is no need to submit PDAs if MRT has an OBA in

effect for a point.


(d) Only one PDA allocation methodology should be applied per

allocation period.


(e) 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.


(f) The allocating party should send back "confirmation" of

receipt of the PDA within 15 minutes.


(g) There are two types of allocations: daily and monthly.
