daily variations, which are considered imbalances, will be

accrued and are subject to resolution under Section 4.7.

Shipper's daily variation shall not exceed ten percent

(10%) of the actual deliveries, except that Midwest may

allow greater variation, and/or may adjust receipts or

deliveries of gas hereunder, if it determines that it may

do so to achieve elimination of previous imbalances without

adverse effect on Midwest's operations or its ability to

meet all its other obligations, including lower priority

service. All daily variations in excess of this 10%

tolerance level will be subject to a Daily Balancing Charge

set forth on Sheet No. 4.


3.2 Daily Operating Tolerances During Extreme Conditions. When

Midwest declares an extreme conditions situation as to any

portion of its system, the tolerance level, as defined in

Section 3.1 above, shall be reduced from 10% to 5% and the

charge for variances beyond the reduced tolerance level

shall be $10.00 per Dth as set forth on Sheet No. 4. For

purposes of this Section 3.2, an extreme conditions

situation exists on any portion of Midwest's system when

throughput approaches capacity, when weather conditions so

require, or when operating pressures on the affected

portion are significantly less than or greater than normal

system operating pressures despite Midwest's efforts to

maintain normal pressures and a further decline or increase

in operating pressures would impair Midwest's ability to

receive or deliver Quantities of Gas in accordance with its

service obligations. Midwest may declare an extreme

conditions situation for the portion of its system affected

by the extreme conditions situation by notifying the meter

operator(s) and Shipper(s) through its EBB and by telephone

and facsimile communication. Once declared, Midwest will

post notification of the extreme conditions situation on

its EBB at the commencement of each Day until Midwest

notifies the meter operator(s) and the Shipper(s) through

its EBB and telephone and facsimile communication that the

extreme conditions situations has ended. When an extreme

conditions situation is declared to become effective at any

time other than the commencement of any Day, Shippers will

use their best efforts to bring deliveries to nominated

levels as soon as possible but in no event later than two

hours, after which the increased Daily Balancing Charge

provided for in this Section 3.2 shall be applied to
