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.




23.1 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
