Pipeline monthly the following:

A. An Imbalance Fee. A charge per Dt per Day, equivalent

Imbalance Fee applicable to such imbalance in excess

of 5% will be doubled.

this Rate Schedule; and

C. All other applicable rates, charges, and penalties as

set forth in the General Terms and Conditions of
