GENERAL TERMS AND CONDITIONS

(continued)

22. NAESB STANDARDS APPLICABLE AND INTERNET WEB SITE:

22.1 General. Transporter shall provide for electronic communication

with its Shippers in compliance with NAESB Standards, and also

shall provide for such electronic communication with third parties

that are not Shippers and are authorized to act on behalf of

Shippers or others interconnected with Transporter's system on a

basis that is not unduly discriminatory. Transporter specifically

shall allow such interface using the protocols, data sets, and

codes detailed in the NAESB Standards. Transporter also may allow

non-standard communication, including use of its own Internet Web

Site and use of paper documents pursuant to agreements among

Transporter, its Shippers, authorized agents of Shippers or other

third parties. References in this Tariff to Transporter's

Internet Web Site or communication or submission of information

"electronically" shall be deemed to mean the utilization, either

directly or via a third-party service provider, of the electronic

data interchange system accessible via Transporter's Internet Web

Site, or the use of NAESB X-12 data sets via the Internet, as such

electronic methods may be effective and compatible with

Transporter's system from time to time. If Transporter determines

that an electronic method does not support the submission of an

item of information required by this Tariff to be submitted

electronically, the information may be communicated in writing by

other means. Transporter shall maintain an Internet Web Site

available to all Shippers and prospective Shippers, which shall

contain information relevant to the availability of the services

provided under this Tariff, in the manner and level of detail

required by the Commission's regulations, as in effect from time

to time. The following information will be accessible on the

Internet Web Site: effective transportation rates; discount

information; information required by the Commission's Standards of

Conduct; storage capacity availability, levels of working Gas and

injection/withdrawal capability and schedules; major Receipt and

Delivery Points; Gas control and operational issues; notices and

information prescribed by various provisions of the Tariff,

including, but not limited to, Sections 5.8 and 20; maintenance

information; applicable fees and usage charges for the Internet

Web Site charged by the Internet Web Site service provider; and
