GENERAL TERMS AND CONDITIONS

28. ELECTRIC POWER COSTS TRACKER

28.1 General. Transporter's Electric Power Costs Tracker shall be

revised prospectively to reflect overcollections and

undercollections of electric power costs incurred by Transporter

for compression of natural Gas.

28.2 Definitions. The definitions of terms applicable to this section

are as follows:

Electric Power Costs ("EPC") shall mean the cost of electric power

purchased by or for Transporter to be used in the operation of

compressor stations and other field locations. EPC shall also

include any related stranded costs or other surcharges imposed by

electric power suppliers that may be billed or allocated to

Transporter.

Base Period shall mean, for the April 1 filing, the twelve Months

ended the previous December 31, and for the October 1 filing, the

twelve Months ended the previous June 30.

EPC Tracker shall mean the rate applicable to Transporter's Rate

Schedules.

Recovery Period shall mean the period during which the revised EPC

Tracker will be in effect.

28.3 Filing of revised EPC Tracker. Transporter shall file with the

Commission, on or before April 1 and October 1 of each Year, a

schedule of EPC Tracker, as determined in accordance with Section

28.4 hereof, to be effective for the Recovery Period beginning

May 1 or November 1 of each Year, respectively, together with

supporting documentation.

28.4 For each transportation rate schedule, the revised EPC Tracker

shall be calculated on the basis of the difference between (a) the

actual electric power costs billed during the Base Period and (b)

the amount of electric power costs collected by Transporter during

the Base Period. This difference shall be divided by projected

throughput to determine the EPC Tracker rate to be in effect

during the Recovery Period.
