THE HIGH AVAILABLE DAILY WITHDRAWAL QUANTITY FORMULA

Applies to the High Deliverability Entitlement Curve

%MDWQ = 29.8636163+(%MAC*0.9673205)+

(%MAC^2*0.0272168)-(%MAC^3*0.0003703)

This formula is only applicable as further defined within the Tariff.

The formula only applies to the sloping portion of the curve.

The following conditions and rules determine the use of the formula:

If the %MAC is > or = to 50.0%

then set the %MDWQ = to 100%

If the %MAC is < 50.0% and > 0%

then set the %MDWQ = to the Formula

If the %MAC is < or = 0%

then set the %MDWQ = to 0%

NOTE: In the context of this table and formula, the %MAC and %MDWQ values

are taken as whole numbers, and not as decimal only numbers (i.e.,

use 40.0 not 0.40 or use 36.1234 not 0.361234).

NOTE: The coefficients are entered with seven decimal places, and the

table is calculated with seven decimal places, and then rounded for

display purposes.

NOTE: To calculate ADWQ from this table or the formula:

ADWQ = {("%MDWQ"/100)*The 100% MDWQ Value} Rounded to the nearest

whole Dekatherm (an integer).
