10.5 Allocation of Delivery Quantities

(b)(ii)Swing PDA Method (Continued)

(D) The DP Operator may elect to use IHSW service in

association with a Swing TSA to cover all TSAs under

which gas is delivered at the Delivery Point. The

DP Operator's use of IHSW service shall not be

restricted to the TSA under which excess quantities

were delivered. The IHSW charges shall be billed on

only the hourly delivery quantities allocated to the

Swing TSA that exceed the Safe Harbor Tolerance

Quantities determined in accordance with Section

10.5(b)(ii)(C)(2). In addition, IHSW service shall

not be applicable to the aggregate sum of any hourly

variation greater than 160% of 1/24th of the daily

scheduled quantities for each TSA under which gas is

delivered at the Delivery Point.

(E) The Swing TSA Shipper will be invoiced any

applicable hourly scheduling penalties, SOC or COC

penalties and, if it has identified an IHSW

agreement associated with a Swing TSA for all of the

TSAs under which gas is delivered at its Delivery

Point, all applicable IHSW charges.


(F) Transporter shall allocate to the Swing TSA all end-

of-month imbalance with respect to scheduled

quantities at the Delivery Point and calculate the

percentage for such imbalances pursuant to Section



(iii) Daily unauthorized overrun penalties - For purposes of

determining daily unauthorized overrun penalties,

allocated gas quantities and, separately, contract

entitlements will be aggregated for a Shipper with

multiple TSAs (inclusive of TSAs of different rate

schedules). Shipper aggregated gas quantities are

accounted for as if service was under a single TSA,

including the computation of the daily Safe Harbor

Tolerance Quantities. Thus, the daily unauthorized

overrun penalties will be calculated by Transporter and

billed to the Shipper based on the comparison between the

sum of all of the Shipper's allocated daily delivered

quantities and of its total TCDs under all of the

Shipper's firm TSAs. Any quantities that are allocated

to one Shipper under either the Pro Rata or Swing method

will not be utilized in calculating the quantity of daily

unauthorized overrun penalties for any other Shipper.
