(h) Transporter will post on its EBB, within 24 hours after making the calculations, each CHDP

value Transporter calculates at the Monitoring Points. Transporter will perform the CHDP calculations for

Section 25.2, using the Peng-Robinson equation of state and C6+ assumptions consistent with industry practices.

Upon a Shipper's request and expense, Transporter will perform a C9+ analysis at that Shipper's receipt or

delivery point, provided that in no event will Transporter be required to perform a C9+ analysis at any one

receipt or delivery point more frequently than once every twelve months, except if a new source of supply has

been added at that point.


25.3 Acceptance of Non-Conforming Gas. If the gas received by Transporter from any source ever fails to

meet the specifications in Sections 25.1 or 25.2, then Transporter may elect to either continue to receive gas

or refuse to take all or a portion of that gas until the gas is brought into conformity with these

specifications. Nothing in this Section 25.3 will prevent Transporter from waiving any quality specifications

in Sections 25.1 or 25.2 where the acceptance of non-conforming gas will not, in Transporter's reasonable

judgment, adversely impact Transporter's operations, or adversely affect the ability of gas to be accepted for

delivery at interconnects with interstate or intrastate pipelines, end-users and local distribution companies.

Transporter will post all waivers granted pursuant to this provision on its EBB.


25.4 Operational Flow Orders. None of the specifications and restrictions set forth in Sections 25.1 or

25.2 shall be deemed to negate, reduce or limit Transporter's authority to issue Operational Flow Orders

consistent with Section 17 of the General Terms and Conditions of this Tariff to provide for the safe and

reliable operation of its system.
