(Continued)

10.1(a) (Continued)

be allocated, Transporter shall use the Ranks provided

priorities to the extent that use of such Rank is not

in conflict with other provisions of this Tariff.

(v) Transporter may enter into Operational Balancing

Agreements ("OBA") at a Point of Injection or

Withdrawal with the Interconnecting Party. An OBA is a

contract between Transporter and an interconnecting

operator which specifies the procedures to manage

operating variances at an interconnect. (NAESB

Definition 2.2.1) The form of agreement used by

Transporter follows the format of the Model OBA

developed by NAESB. Locations covered by an effective

Tariff is interrupted consistent with this Section,

Transporter shall not be liable for damages resulting

from the implementation of the procedures described

herein.

(b) Absent agreement to a PDA methodology, quantities at each Point

of Injection or Withdrawal shall be allocated pro rata based on

Scheduled Quantities (Confirmed Quantities). (NAESB Standard

2.3.18)

the Gas has flowed is within one Business Day after end of Gas

Day. If the best available data for reporting daily operational

allocations is the Scheduled Quantity, that quantity should be

used for the daily operational allocation (NAESB Standard

2.3.21).

allocated quantities should rest with the party

responsible for accepting NAESB allocation types. The

party receiving Nominations should provide allocation
