shall be applicable to the quantities delivered for the

account of Customer under all of Pipeline's Rate Schedules.

21.3 Basis of the ACA Surcharge. The ACA Surcharge shall be

that increment, adjusted to Pipeline's measurement basis

(Dth), which has been approved by FERC orders approving an

annual charge unit rate.

21.4 Filing Procedure. The initial ACA Surcharge or any

subsequent changes in such surcharge shall be filed by

Pipeline at least thirty (30) Days prior to the proposed

effective date unless the establishment by the FERC of the

annual charge unit rate for a particular fiscal year

prohibits Pipeline from making a timely filing, whereupon

the FERC's notice requirements under its regulations shall

be deemed waived for purposes of this Section 21.4.

The proposed effective date of filings pursuant to this

subsection shall be the effective date prescribed by the

Federal Energy Regulatory Commission. Such filing shall
