1.2 "Average Thermal Content of Gas in Storage" ("ATC") shall be

calculated by dividing the Dekatherms by the Volume, in Mcf, in

Transporter's Storage Field, excluding base Gas, at a point in time.

The ATC shall be assumed to be 1,000 Btu per cubic foot for purposes

of contract entitlement and rate design. Transporter shall monitor

storage injections and withdrawals and calculate the actual ATC of

Gas in storage on October 31 of each year. If the actual ATC

deviates from the currently effective ATC by more than plus or minus

20 Btu per cubic foot, the actual ATC shall become the new effective

ATC and shall be posted on Transporter's electronic bulletin board

on or about November 15 of each year, and a corresponding adjustment

will be made to Rate Schedule FS-1 Shipper's MDIQ, MDWQ and MAC

entitlements and Rate Schedule IS-1 MDQ and MAC. Transporter may

make these annual adjustments for smaller changes in Btu per cubic

foot values if in Transporter's judgment such change is required to

avoid system disruption. The adjustment will be posted on

Transporter's electronic bulletin board as a percentage increase or

decrease in entitlements and each firm storage Shipper's adjusted

entitlements will also be posted. The adjusted entitlements will

take effect upon the first of the Month following posting on

Transporter's electronic bulletin board. If an adjustment pursuant

to this Section causes Shipper to be in an overrun situation,

Shipper will have 30 Days before being subject to overrun charges.

When an adjustment to storage contract entitlement is made pursuant

to this Section, a corresponding adjustment to storage rates will

also be made effective the first of the Month, the Month following

the date such adjustment is posted on Transporter's electronic

bulletin board.


1.3 "Begin Date" shall mean the Day specified by a Shipper on which a

Gas transaction is to begin. Most Gas transactions are to be

effective for a full Gas Day. However, Shippers may indicate a

requested beginning time when submitting Intraday Nominations.


1.4 "Bidding Shipper(s)" is any Shipper who is prequalified pursuant to

Section 9 of the General Terms and Conditions to bid for capacity

or who is a Party to a prearranged release.


1.5 "Btu" shall mean 1 British thermal unit, which is the amount of

heat required to raise the temperature of 1 pound of water 1 degree

from 59 to 60 degrees Fahrenheit. The reporting basis for Btu is

14.73 p.s.i.a. and 60 degrees F (101.325 kPa and 15 degrees C, and

dry). Standardize the reporting basis for gigacalorie as 1.035646

Kg/cm^2 and 15.6 degrees C and dry. Thermal conversion factors

shall be stated using not less than three decimal places. However,

for calculation purposes, not less than 6 decimal places should be

used. (NAESB Standards 2.3.9 and 2.3.10)
