For purposes of this section, the Net Monthly Imbalance will

be based upon Actual Data.

In the event this publication or specific postings contained

therein are discontinued, are not representative of market

conditions, or as Delivery Points are added to or removed

from Transporter's Facility, Transporter will revise this

Subsection 13.3(d) to substitute another price index

generally accepted in the natural gas industry. Until

Transporter receives approval from the Commission to use

such substitute index, Transporter will continue to

calculate the Index Price each month based on the remaining

representative indices.

(e) A prior period adjustment that impacts the Net Monthly

Imbalance amount for a prior period shall be multiplied by

the price assessed in the production month corresponding to

the month in which the imbalance occurred. No imbalance

penalty should be imposed when a prior period adjustment

applied to the current period causes or increases a current

month penalty.
