be the unit charge, adjusted to Pipeline's pressure base and

heating value, if required, which has been established by the

FERC. The ACA charge shall be applied to the commodity

component of transportation and sales rates.

22.4 The ACA shall be filed by the Pipeline at least thirty (30)

days prior to the proposed effective date unless, for good

cause shown, lesser periods are allowed by valid Commission

order. The proposed effective date of filings shall be

October 1 of each year. Any such filing shall not become

effective until it becomes effective without suspension or

refund obligation.

23. MEASUREMENT

23.1 The standard unit of measurement shall be one (1) Dkth or MMBtu,

consisting of one million (1,000,000) Btus. Quantities

measured at other temperatures and pressures shall be computed

into such units, giving effect to the deviation of gas from

Boyle's law.

23.2 The average atmospheric (barometric) pressure shall be assumed

to be 14.7 pounds per square inch, irrespective of the actual

elevation or location of delivery points above sea level or of

variations in such barometric pressure from time to time.

23.3 When orifice meters are used for the measurement of gas, the

computation of the quantities of gas shall be made in

accordance with the provisions of Gas Measurement Committee

Report No. 3, or any succeeding report, of the American Gas

Association, as changed from time to time, with any subsequent

amendments or revisions thereof now or hereafter made. The

flowing temperature and specific gravity of the gas at the

point of measurement shall be determined by Pipeline as

follows:

(a) The flowing temperature of the gas shall be determined

by means of a recording thermometer of standard

manufacture so installed that it may properly record the

temperature of the flowing gas. The average, taken from
