13.7 Calculation of Monthly Imbalances. A Shipper's imbalance under a par-

ticular service agreement is always equal to the amount of gas re-

ceived by Transporter for that Shipper's account under that agreement,

less the amount Transporter delivers to that Shipper under that agree-

ment, and less fuel and loss retention, adjusted for imbalance payback

and relief. Imbalances can be either positive (adjusted receipts for

Shipper's account exceed deliveries to Shipper) or negative (deli-

veries to Shipper exceed adjusted receipts for Shipper's account).


Each month, Transporter will calculate the imbalance for each

agreement (from among all the receipt and deliver points used under

that agreement) and aggregate those calculations into that agreement's

Monthly Imbalance. The Monthly Imbalances for all the agreements in

effect for a single Shipper are set off against each other to calcu-

late the Monthly Shipper Imbalance. Each Monthly Shipper Imbalance is

aggregated with any cumulative unresolved imbalance from previous

months into the Shipper's Cumulative Monthly Imbalance. The Cumu-

lative Monthly Imbalance is compared to a Monthly Imbalance Tolerance

Level ("MITL"), which is equal to 5 percent of the accumulated daily

scheduled receipts for the month under all that Shipper's agreements,

but at least 1000 Dth.


If a Shipper indicates its consent in writing delivered to Trans-

porter, or by E-Mail message on the Web Site, Transporter will trans-

mit a Shipper's Monthly Imbalance Statement by E-Mail message on the

Web Site.


13.8 Transportation Balancing Fee. Imbalances in excess of one MITL rep-

resent unauthorized use of Transporter's system facilities. If the

Monthly Shipper Imbalance quantity causes the Cumulative Monthly

Imbalance to exceed one MITL a Transportation Balancing Fee will be

charged on the amount in excess of tolerance, except as otherwise

provided in this Section 13.8. The schedule for this fee per Dth is

as follows:
