5. DAILY IMBALANCE CHARGE (Continued)

5.1 Applicability (Continued)

(c) Listing of Balancing Parties Subject to Potential Daily Imbalance Charge

Company shall maintain a list on its Informational Postings web site of

the Balancing Parties that are potentially subject to a Daily Imbalance

Charge under Rate Schedule LMS-MA.

Company shall revise such posting within a Gas Day if the applicability of

the Daily Imbalance Charge for a given Balancing Party changes due to

change in flow control status at one or more interconnects under the

Balancing Party's LMS-MA Agreement.

In addition, Company shall notify a Balancing Party listed pursuant to

this Subsection, by phone, of any status change related to the

applicability of the Daily Imbalance Charge at the time such change is

made.

The amount of Balancing Party's imbalance at the end of a Gas Day will

determine if the Daily Imbalance Charge is potentially applicable to such

Balancing Party.

5.2 Calculation

(a) Net Pipeline Position

By 12 Noon CCT each day, Company shall provide on its Informational

Postings web site a notice of the net pipeline position on Company's

pipeline system for the previous Gas Day.

The net pipeline position is the sum of the total positive and negative

Cumulative Imbalances, based on SCADA data, at all Balancing Party

interconnections subject to the Daily Imbalance Charge for such Gas Day

under Rate Schedules LMS-MA and LMS-PA.

A positive net pipeline position indicates that gas has been stored on

Company's pipeline and is due others. A negative net pipeline position

indicates that gas is due Company.

Company will post a notice that the Daily Imbalance Charge will not be

applicable for a given Gas Day, if Company determines that inaccurate

SCADA data exists for such Gas Day to calculate a net pipeline position.

(b) Allowable Swing Quantity (ASQ)

The Balancing Party's ASQ for a given Gas Day is the greater of

(1) 1000 Dekatherms or (2) 10 percent of the highest daily Scheduled

Quantity at such designated interconnect(s) during the prior 15 days.

On a given Gas Day, a Balancing Party may take gas in excess of Scheduled

Quantities or not take delivery of all Scheduled Quantities at the

interconnect(s) listed under the Balancing Party's LMS-MA Agreement up to

its ASQ.
