The following procedures have been adopted by Transmission Providers MountainWest Pipeline, LLC; MountainWest Overthrust Pipeline, LLC and White River Hub, LLC to comply with the Standards of Conduct promulgated pursuant to FERC Order No. 717.

II. Non-Discrimination Requirements

The Transmission Provider will comply with the requirements section 358.4(a)-(d) of the Standards of Conduct. The Transmission Provider must treat all Transmission Customers, whether affiliated or not, on a not unduly discriminatory basis, and must not make or grant any undue preference or advantage to any person or subject any person to any undue prejudice or disadvantage with respect to the sale or purchase of Transmission service.

The Transmission Provider will strictly enforce all tariff provisions relating to the sale or purchase of open access Transmission service if these tariff provisions do not permit the use of discretion.
The Transmission Provider will apply all tariff provisions relating to the sale or purchase of open transmission service in a fair and impartial manner that treats all Transmission Customers in a non-discriminatory manner if the tariff provisions permit the use of discretion.
The Transmission Provider may not, through its tariff or otherwise, give undue preference to any person in matters relating to the sale or purchase of transmission service (included issues of price, curtailment, scheduling, priority, ancillary services, or balancing).
The Transmission Provider will process all similar requests for transmission service in the same manner and within the same period of time.

III. Independent Functioning Rule

As defined in section 358.5 (a) of the Standards of Conduct, except as described in Parts III.A and V.H below, the Transmission Provider’s Transmission Function Employees shall function independently of its Marketing Function Employees.

As provided in section 358.5 (b)(1)(ii) no MFE will have access to the Transmission Provider’s gas control or system operations centers, or any similar Transmission Provider facilities used for day-to-day transmission operations or reliability functions that differs in any way from the access available to other Transmission Customers.

The no-conduit rule will apply to all Williams employees and to those of its subsidiaries and Affiliates, and to any contractor, consultant or agent of Williams and its subsidiaries and Affiliates. The Transmission Provider has accordingly implemented policies and procedures to assure that it will not use anyone as a conduit for the disclosure of non-public Transmission Function Information to its Marketing Function Employees.
