10.6 Allocation of Receipt Quantities

(b) PDA Methods for the Allocation of Receipt Point Quantities.

(i) Pro Rata Allocations at a Receipt Point - For each Gas

Day, the difference between daily quantities measured

and scheduled for all agreements under which gas is

received at a Receipt Point will be allocated on a pro

rata basis to each agreement scheduling gas from that

Receipt Point. The Pro Rata allocation will be

determined by dividing each agreement's scheduled

quantities by the total of all scheduled quantities

from the Receipt Point.

(A) This method shall be calculated by taking the

total quantities to be allocated and multiplying

such quantities by the ratio established from

taking each individual scheduled line item and

dividing it by the total of all scheduled line

items applicable to the quantities to be

allocated.

(B) Transporter shall allocate pro rata, among all

agreements under which gas is scheduled from a

Receipt Point, all end-of-month imbalances with

respect to scheduled quantities at the Receipt

Point and calculate the percentage for such

imbalances pursuant to Section 10.3(d).

(ii) Swing Allocations at a Receipt Point - For each Gas

Day, each agreement scheduled at a Receipt Point will

be allocated gas quantities from such Receipt Point

equal to the scheduled quantities under the agreement.

Additionally, the TSA identified as the "Swing TSA"

for each Receipt Point will be allocated the

difference between 1) the sum of the total daily

quantities measured and 2) the total daily quantities

scheduled to the Receipt Point under all rate

schedules.

(A) Any TSA for service under Rate Schedules IT-1,

FT-1, FT-2, FTH-V or FT-H, may be designated by

the RP Operator at a Receipt Point as the Swing

TSA.
