Extraordinary Gas Losses





From time to time, Pipeline may experience extraordinary

losses of gas from storage. These losses may be caused by a

variety of factors, including mechanical failure of a storage

well or wells, changes in storage reservoir hydraulics,

migration, or differences between expected and actual reservoir

operation. Pipeline's customers are therefore placed on notice

that Pipeline may seek rate recovery for such extraordinary

storage gas losses. Pipeline may propose to amortize

extraordinary storage gas losses through its base rates only in

a general NGA Section 4 rate change filing. Customers and other

parties to such proceeding may challenge Pipeline's proposed

rate recovery for extraordinary gas losses on any basis;

provided, however, that they shall not be permitted to argue

that parties received inadequate notice. For purposes of this

section, the term "extraordinary" shall be defined by reference

to the Commission's accounting regulations.
