(2) Interruptible Transportation Revenue Credits on Medford



(a) Applicability. Revenue credits from interruptible

transportation revenues received by PG&E GT-NW from Rate

Schedule ITS-1 (E-1) Shippers shall be credited to the

deferred account for Washington Water Power Company's WP

Natural Gas subsidiary in accordance with the mechanism

approved by Order of June 1, 1995, 71 FERC Paragraph



(b) Crediting Percentage. PG&E GT-NW shall credit to the

deferred account 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 PG&E GT-NW as part of designing PG&E GT-NW's

effective transportation rates during such 12-month

period. To the extent that PG&E GT-NW is required

to provide interruptible 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", PG&E GT-NW 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 interruptible

transportation revenue credit due under the provisions

of this paragraph, where applicable, such pro rated Cost

Allocation Amount shall be compared to PG&E GT-NW's

actual interruptible revenues for the Short Period.


(c) Exclusion. Revenue credits shall not be awarded for

that portion of interruptible revenues that are

attributable to the recovery by PG&E GT-NW of variable

costs, which portion shall be equal to the minimum

usage charge for Rate Schedule ITS-1 (E-1).
