GENERAL TERMS AND CONDITIONS

the unit charge rate shall be reflected on Sheets

No. 10 and 11 of Second Revised Volume No. 1 and

Sheet No. 1A of Original Volume No. 2 of this FERC

Gas Tariff. The ACA unit charge shall be included

in the commodity component of any rate schedule

with two-part rates.

Regulations. In the event, however, the

Commission's establishment of such annual charge

unit rate for a particular fiscal year prohibits

requirements under Section 154.22 shall be deemed

waived for purposes of this Section 29.
