notwithstanding any other provision in this tariff or

any service agreement or contract with Seller.


(a) Definitions: Affected Services are those subject to

curtailment under this Section 22 and include all

deliveries under Seller's S Rate Schedule. Affected

Customers are customers receiving Affected Service.

The Volume Available for Affected Services for any

Curtailment Period (consisting of a day, a series of

consecutive days, a month, or a period of consecutive

months) is the total volume of gas which Seller

determines it will be able to deliver for Affected

Services during the Curtailment Period.


(b) Method of Curtailment: Seller shall periodically

determine the Volume Available for Affected Services

for appropriate Curtailment Periods. If such volume

is less than the estimated requirements of Affected

Services for the period involved, Seller shall

determine the Curtailment Period Quantity

Entitlement (CPQE) which each Affected Customer shall

be entitled to receive for Affected Services during

that Curtailment Period. Seller shall promptly

notify each Affected Customer of its Curtailment

Period Quantity Entitlement and the Curtailment

Period during which it will apply, as far in advance

and for as long a period of time as is possible and

reasonable. Seller may change announced CPQE if

conditions so require.


The CPQE for each Affected Customer for each Affected

Service shall be determined by allocating volumes to

each such customer based on the customer's

requirements for each partial and/or full month

involved in the priority of service categories set

forth in Section 22.2(c) of this Section 22.2. Such

allocation shall be accomplished by assigning to each

customer its requirements in each successive

category beginning first with the highest (category

0) and continuing successively to each lower

category, until the total volumes allocated to all

Affected Customers equal the Volume Available for

Affected Services. If such Volume Available for

Affected Services is reached by assigning only a

portion of the requirements of all Affected Customers
