GENERAL TERMS AND CONDITIONS

(h) Except in cases where the Percentage or Operator

Provided Value method of allocation is being employed,

where there is:

(i) sufficient gas to fulfill all scheduled

quantities at a location, a PDA should not result

in a quantity being allocated to a party,

contract, or transaction, as applicable, that is

less than the corresponding scheduled

quantity(ies) for that party, contract or

transaction, as applicable.

(ii) insufficient gas to fulfill all scheduled

quantities at a location, a PDA should not result

in a quantity being allocated to a party,

contract, or transaction, as applicable, that is

greater than the corresponding scheduled

quantity(ies) for that party, contract, or

transaction, as applicable.

In the event of conflicts between this standard and

the Transporter’s tariff or general terms and

conditions, the latter will prevail.

(i) Parties should communicate to their counter

parties that their transaction(s) for allocation

purposes are lowest ranked or swing, when such counter

parties’ transaction(s) are identified by the party as

being the lowest ranked or swing. This standard does

not apply to the relationship between the Transporters

and their Shipper.

(j) Under normal operating conditions, at a location,

which is covered by an OBA, the scheduled quantity

should be the allocated quantity.

7.5 A new allocation detail may be needed when a

nomination changes.

7.6 The timing for reporting daily operational

allocations after the gas has flowed shall be within one

business day after the end of the Gas Day. If the best

available data for reporting daily operational allocations

is the scheduled quantity, that quantity shall be used for

the daily operational allocation.
