8. OPERATING PROVISIONS

8.1 FIRM SERVICE (Continued)

(i) Hourly Entitlement Enhancement Nomination (Continued)

(ii) HEEN Specifications. The hourly rates of flow supported by

HEEN are pursuant to the applicable rate schedule. At HEEN

Qualified Delivery Points, when applicable, quantities

delivered, or caused to be delivered, for Shipper's account

may not exceed in any hour the sum of the effective hourly

entitlements based on the Shipper's contract and the scheduled

quantity, as follows:

(A) A HEEN may be used to reserve capacity to support non-

uniform hourly deliveries at HEEN Qualified Delivery

Points that are listed on Transporter's EBB. HEEN

nominations must meet all other criteria for a valid

nomination, except the requirement that the receipt side

of the nomination be confirmed by a third party. The

HEEN quantity and the Flowing Gas quantity scheduled for

the path may not exceed the TCD for primary delivery

points or Path Quantity for the Flow Path used. HEEN

nominations will be available up to 100% of all of a

Shipper's unscheduled MDQ across all of its TSAs at each

Delivery Point between the Shipper's HEEN Receipt Point

through to its primary delivery point in the pertinent

TSAs. All of the tariff rules as to primary and

alternate path and point scheduling priorities will

continue to apply. The foregoing does not allow summing

or aggregation of the Hourly Scheduled Entitlements

associated with HEEN nominations across all points in a

TSA but is only relevant to the scheduling at a single

Delivery Point.
