27.2 NOTIFICATION PROCEDURES

(a) PRICING

(1) The availability and pricing of services on

Trailblazer's System is governed by this Tariff. From time to time,

Trailblazer changes or updates its Tariff by filings with the FERC.

Each Shipper is notified by Trailblazer of such filings and is

provided a copy of each filing.

(2) Telephone inquiries related to the availability

or pricing of services are answered by representatives of Trailblazer

and upon request, potential Shippers are provided copies of

Trailblazer's Tariff filings.

(3) Shippers desiring a rate under any Agreement

other than the maximum rate on file with the FERC are required to

submit such requests in writing or by electronic medium to the

Manager, Gas Transportation, in Houston. Any lower rate agreed to by

Trailblazer is evidenced in writing to such Shipper, and such rate is

considered confidential until it is reported to the FERC as required

by the Regulations. In order to attract or determine interest in the

use of any particular service, representatives of Trailblazer from

time to time contact Shippers by telephone. Such conversations are

confidential and may or may not result in Shipper submitting a request

for a discounted rate for a particular service.
