(1) Interruptible Transportation Revenue Credits on Coyote Springs



(a) Applicability. Revenue credits from interruptible

transportation revenues received by GTN from Rate

Schedule ITS-1 (E-3) Shippers shall be provided to GTN's

firm Shippers under Rate Schedules FTS-1 (E-3)

("Eligible Shippers"), excluding Shippers receiving

service under a Capacity Release Service Agreement.


(b) Crediting Percentage. GTN shall credit to

Eligible Shippers 90 percent of interruptible

transportation revenues received during each 12-month

period, commencing November 1st of each year, but only

to the extent that such transportation revenues exceed

the amount of fixed costs which were allocated to

interruptible transportation (Cost Allocation Amount) by

GTN as part of designing GTN's effective

transportation rates during such 12-month period. To

the extent that GTN is required to provide inter-

ruptible transportation revenue credits during any period

during which this Paragraph 35A shall be or shall have been

in effect for less than 12 months,a "Short Period", GTN

shall pro rate the Cost Allocation Amount by the number

of days during such Short Period as compared to the total

number of days in such 12 months. To calculate the inter-

ruptible transportation revenue credit due under the

provisions of this paragraph, where applicable, such pro

rated Cost Allocation Amount shall be compared to GTN's

actual interruptible revenues for the Short Period.


(c) Timing of Credits. Within 45 days after November 1st of

each 12-month period or after the end of a Short Period,

if applicable, GTN shall determine the total

amount of the applicable Rate Schedule ITS-1 (E-3)

revenues received during the 12-month period or Short

Period and the distribution of the interruptible revenue

credits due to Eligible Shippers as described below.

Such revenue credits shall be reflected as a credit

billing adjustment in the next invoices rendered to the

Eligible Shippers. In the event that such credit

billing adjustment would result in a credit total

invoice to any Shipper, GTN will refund the

excess credit billing adjustment to the Shipper in cash

within 15 days after determination of the amount of the

credit due to the Shipper. (Continued)
