25.7 Odorization. Transporter and Shipper may agree, or governmental authorities may require, that the gas

be odorized by use of a malodorant agent of such character as to indicate by a distinctive odor the

presence of gas. Whenever odorized gas is delivered, the quality and specifications of such gas, as set forth

in this Section 25, shall be determined prior to the addition of malodorant and with proper allowance for

changes or additions to the gas due to such malodorant. Such odorization of the gas by the Transporter,

unless otherwise mutually agreed by Shipper and Transporter, shall be for the purpose of detection of the gas

only during the time it is in possession of the Transporter, prior to delivery to the Shipper.


25.8 Acceptance of Non-Conforming Gas. If gas received by Transporter ever fails to meet the specifications

in this Section 25, then Transporter may elect to either continue to receive such gas pursuant to the waiver

procedures of Section 25.9 or refuse to take all or any portion of such gas until that gas is brought into

conformity with the specifications in Section 25. None of the specifications and restrictions set forth in

this Section 25 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.
