Attorney

In support of this Application, Intennountain does allege and state as follows:
APPLICATION - 2
Intennountain is a gas utility, subject to the jurisdiction of the Idaho Public Utilities
Commission, engaged in the sale of and distribution of natural gas within the State of Idaho under
authority of Commission Certificate No. 219 issued December 2, 1955, as amended and
supplemented by Order No. 6564, dated October 3, 1962.
Intennountain provides natural gas service to the following Idaho communities and counties
and adjoining areas:
Ada County - Boise, Eagle, Garden City, Kuna, Meridian, and Star;
Bannock County - Chubbuck, Inkom, Lava Hot Springs, McCammon, and Pocatello;

Washington County - Weiser.
Intennountain s properties in these locations consist of transmission pipelines, a compressor
station, a liquefied natural gas storage facility, distribution mains, services, meters and regulators
and general plant and equipment.
II.
Intennountain seeks with this Application to pass through to each of its customer classes a
change in gas related costs resulting ITom: 1) an increase in costs billed Intennountain pursuant to
General Rate Cases filed by Northwest Pipeline Corporation ("Northwest" or "Northwest
Pipeline ) and Gas Transmission Northwest Corporation ("Gas Transmission Northwest" or
APPLICATION - 3
GTN"), 2) benefits included in Intennountain s flITll transportation and storage costs resulting
from Intennountain s management of its storage and finn capacity rights on pipeline systems
including Northwest Pipeline and GTN, 3) a decrease in Intennountain s Weighted Average Cost
of Gas ("W ACOG"), 4) an updated customer allocation of gas related costs pursuant to the
Company s Purchased Gas Cost Adjustment provision, and 5) the inclusion of temporary
surcharges and credits for one year relating to gas and interstate transportation costs ITom
Intennountain's deferred gas cost account. Exhibit No.3 contains pertinent excerpts ITom pipeline
and related facilities' tariffs. Intennountain also seeks with this Application to eliminate the
temporary surcharges and credits included in its current prices during the past 12 months, pursuant
to Case No. INT-05-2. The aforementioned changes would result in an overall price decrease to
Intennountain s RS-, RS-, GS-, and LV-1 customers, a price decrease to Intennountain s T-
customers, and an increase in Intennountain s T-2 Demand Charge and a decrease to the T-
Commodity Charge.
These price changes are applicable to service rendered under rate schedules affected by and
subject to Intennountain s Purchased Gas Cost Adjustment ("PGA"), initially approved by this
Commission in Order No. 26109, Case No. INT-95-, and additionally approved through
subsequent proceedings.
Exhibit No.4 summarizes the price changes in: 1) Intennountain s base rate gas costs and its
rate class allocation, and 2) adjusting temporary surcharges or credits flowing through to
Intennountain s direct sales and transportation customers. Exhibit No.s 3 and 4 are attached hereto
and incorporated herein by reference.
III.
The current prices of Intennountain are those approved by this Commission in Order
No. 29875, Case No. INT-05-
IV.
Intermountain s proposed prices incorporate all price changes impacting Intennountain
finn interstate transportation capacity including, but not limited to, any such changes
implemented by Northwest and GTN which have occurred since Intennountain s last PGA filing
in Case No. INT-05-2. Exhibit No., Lines 1 through 23 , details the proposed changes in
APPLICATION - 4
Intermountain s prIces resulting from adjustments to Intennountain s cost of interstate and
upstream capacity from its various suppliers.
On June 30, 2006, Northwest Pipeline Corporation filed a general system rate case with
the Federal Energy Regulatory Commission ("FERC") in Docket No. RP06-416-000. This filing
is the first general rate increase sought by Northwest in nearly ten years. The FERC suspended
the effective date of Northwest's proposed rates until January 1 , 2007, subject to refund and
conditions and the outcome of the FERC hearing. Intennountain s proposed prices have been
weighted to reflect this January 1 , 2007 effective date. Intennountain has representation at FERC
to intervene in Northwest's General Rate Case proceeding.
Intennountain transports natural gas from Alberta on the Gas Transmission Northwest
system from the international border at Kingsgate to the interconnection with Northwest Pipeline
at Stanfield. On June 30, 2006, GTN filed a general system rate case with the Federal Energy
Regulatory Commission in Docket No. RP06-407-000. The FERC suspended the effective date
of GTN's proposed rates until January 1 2007, subject to refund and conditions and the outcome
of the FERC hearing. lntennountain s proposed prices have been weighted to reflect this January
, 2007 effective date. GTN's current rates are based on its last rate case, filed in 1994.
Intennountain has representation at FERC to intervene in GTN's General Rate Case proceeding.
Intennountain is party to certain agreements whereby Intennountain manages its storage
related assets in conjunction with a third party asset manager. Intennountain proposes to pass back
to its customers the benefits generated from these agreements as included on Exhibit No., Line
19.
The W ACOG reflected in Intennountain s proposed prices is $0.72400 per thenn, as shown
on Exhibit No., Line 24, Column (t). This compares to $0.73219 per thenn currently included in
the Company s tariffs.
As stated in the Company s Customer Notice, despite a 30% increase in crude oil
prices during this past year when the Company last changed its natural gas prices, the Company has
not increased in its Application the natural gas cost to its customers. Natural gas prices have been
moderated by historically high levels of natural gas stored in the nation s inventory; natural gas
production, which was shut-in after the impact of Hurricane Katrina, has now largely come back
APPLICATION - 5
on-line in the Gulf of Mexico and the outlook for the upcoming hurricane season is moderate as
compared to last season; and price induced domestic natural gas rig counts and production are up as
compared to a year ago.
The proposed W ACOG includes the benefits to Intennountain s customers generated by
Intermountain s management of significant natural gas storage assets whereby gas is procured
during the traditionally lower priced summer season for withdrawal and use during the winter when
prices would otherwise be substantially higher. Additionally, and in an effort to further stabilize the
prices paid by our customers during the upcoming winter storage withdrawal period, Intennountain
entered into hedging agreements to lock-in the price for 100% of the company s April 2006 to
October 2006 storage injections.
Intennountain also believes that the W ACOG proposed in this Application, subject to the
effect of actual supply and demand, will likely materialize during the upcoming PGA period
because Intennountain is planning to employ, in addition to those natural gas hedges already in
place for the high winter demand, cost effective financial instruments to secure those prices
embedded within the filed W ACOG when and if those pricing opportunities materialize in the
marketplace.
However, liquidity in the market is sustained by contrary opinions and natural gas prices
could indeed realize levels different from those included in this Application. Although current
commodity futures prices dictate the use of this $0.72400 per thenn W ACOG, Intennountain
continues to remain vigilant in monitoring natural gas prices and is committed to come before this
Commission prior to this winters heating season with an Application to further amend these
proposed prices, should these forward prices materially deviate from the $0.72400 per thenn.
Timely natural gas price signals and the accounting for any cost differences brought about
by these volatile markets, facilitated through the use of the PGA mechanism, enhances our
customers' ability to make timely and infonned energy use decisions and ensures they only pay the
actual cost of such supplies. It is important to continue to alert our customers in a timely manner to
these impending increases before their higher natural gas usage is before them. By employing the
use of customer mailings and various media resources, Intennountain will continue to educate its
customers regarding the wise and efficient use of natural gas, billing options available to help our
customers manage their energy budget, and pending natural gas unit price changes.
APPLICATION - 6
VI.
Pursuant to Case No. INT-05-, Intennountain has included temporary surcharges and
credits in its October 1 , 2005 prices for the principal reason of collecting or passing back to its
customers deferred gas cost charges and benefits, as outlined in Case No. INT -05-2. Line 29 of
Exhibit No.4 reflects the elimination of these temporary surcharges and credits.
VII.
Intennountain s PGA tariff includes provisions whereby Intennountain s proposed prices
will be adjusted for updated customer class sales volumes and purchased gas cost allocations
pursuant to the Company s approved cost of service methodology. Intennountain s proposed prices
include a fixed cost collection adjustment pursuant to these PGA provisions, as outlined on Exhibit
No., Line 24. The price impact of this adjustment is included on Exhibit No., Line No. 30.
Exhibit No.5 is attached hereto and incorporated herein by reference.
VIII.
Intennountain is party to certain agreements whereby Intennountain has released segmented
portions of its finn capacity rights when not needed to meet its customer needs. Intennountain
proposes to pass back to its customers the benefits generated from the capacity release agreements
totaling $3.5 million. Exhibit No., Line 1 , reflects the inclusion of the $3.5 million credit.
Intennountain proposes to pass back this amount via the per thenn credit as detailed on Exhibit
No.7. Exhibit No.s 6 and 7 are attached hereto and incorporated herein by reference.
IX.
Intennountain proposes to allocate deferred gas costs from its Account No. 186 balance
its customers through temporary price adjustments to be effective during the 12-month period
ending September 30 2007, as follows:
1) Intennountain has been deferring in its Account No. 186 fixed gas costs. The
credit amount shown on Exhibit No., Line 9 , Co!. (b) of$3.1 million is predominantly attributable
to the collection of interstate pipeline capacity costs and the true-up of expense issues previously
ruled on by this Commission. Intennountain proposes to collect or pass back these balances via the
per thenn surcharges and credits, as detailed on Exhibit No.8 and included on Exhibit No., Line
2. Exhibit No.8 is attached hereto and incorporated herein by reference.
APPLICATION - 7
2) Intennountain has been deferring in its Account No. 186 deferred gas cost debits
of $14.1 million, as shown on Exhibit No., Line 2, Co!. (b), attributable to Intennountain
variable gas costs since September 1, 2005. Intennountain proposes to collect this debit balance via
a per thenn surcharge, as shown on Exhibit No., Line 4, Co!. (b) and included on Exhibit No.
Line 3. Exhibit No.9 is attached hereto and incorporated herein by reference.
Intennountain has allocated the proposed price changes to each of its customer classes
based upon Intennountain s PGA provision. A straight cent-per-thenn price decrease was not
utilized for the T -1 tariff. No fixed costs are currently recovered in the tail block of Intennountain
1 tariff. Absent Williams' finn transportation TF-1 Commodity Charge, the proposed decrease
in the T -1 tariff is fixed cost related, and therefore, a cent per thenn decrease was made only to the
first two blocks of the tariff for these fixed costs.
XI.
The proposed increase to the T-2 tariff Demand Charge is fixed cost related, and therefore, a
cent per thenn increase was made to the T-2 Demand Charge for these fixed costs. Additionally, the
proposed decrease to the T-2 Commodity Charge incorporates the decrease in the Williams' finn
transportation TF -1 Commodity Charge.
XII.
Exhibit No.1 0 is an analysis of the overall price changes by class of customer. Exhibit No.
10 is attached hereto and incorporated herein by reference.
XIII.
The proposed overall price change herein requested among the classes of service of
Intennountain will not affect Intennountain s earnings, and is just, fair, and equitable.
XIV.
This Application is filed pursuant to the applicable statutes and the Rules and Regulations
of the Commission.This Application has been brought to the attention of Intennountain
customers through a Customer Notice and by a Press Release sent to daily and weekly newspapers
and major radio and television stations in Intennountain s service area. The Press Release and
Customer Notice are attached hereto and incorporated herein by reference. Copies of this
APPLICATION - 8
Application, its Exhibits, and Workpapers have been provided to those parties regularly intervening
in Intennountain s rate proceedings.
xv.
Intennountain requests that this matter be handled under modified procedure pursuant to
Rules 201-204 of the Commission s Rules of Procedure. Intennountain stands ready for immediate
consideration of this matter.
APPLICATION - 9
WHEREFORE, Intennountain respectfully petitions the Idaho Public Utilities Commission
as follows:
a. That the proposed rate schedules herewith submitted as Exhibit No.2 be approved
without suspension and made effective as of October 1 , 2006 in the manner shown on Exhibit No.
b. That this Application be heard and acted upon without hearing under modified procedure
and
For such other relief as this Commission may detennine proper herein.

Re:Northwest Pipeline Corporation
Docket No. RP06-
Dear Ms. Salas:
Pursuant to Section 4 of the Natural Gas Act, 15 U.C. ~ 717c, and Part 154 of the
regulations of the Federal Energy Regulatory Commission ("Commission ), 18 CFR 154,
Northwest Pipeline Corporation. ("Northwest") tenders for filing as part of its FERC Gas
Tariff, Third Revised Volume No., an original and twelve copies of certain revised tariff
sheets to reflect a general rate increase and pro forma Sheet No.5, together with
supporting rate case statements and schedules. The revised tariff sheets, which are
enumerated herein and included in the filing, are proposed to be effective August 1 , 2006.
Statement of Nature, Reasons and Basis for the Filing':'" 18 CFR 154.7(a)(6)
I. Overview
This general rate case filing reflects various revisions to the rates for jurisdictional
transportation and storage services contained in Northwest's Tariff along with supporting
statements and schedules as required by the Commission s regulations. As background,
this filing represents the first general rate increase that Northwest has filed since its Docket
No. RP96-367 rate application, which was filed approximately ten years ago. Following a
period of several years of "pancaked" rate case filings, Northwest entered into a Settlement
Agreement in Docket No. RP96-367 with its customers which, among other things, was
intended to help Northwest avoid filing repeated rate increases and provide rate stability for
its customers.
In the ten years since the Settlement Agreement, many circumstances have
changed that necessitate increases in the jurisdictional rates reflected in this filing to permit
Northwest the opportunity to recover its cost of service. As shown in Statement G of this
filing, revenues at current rates are inadequate to recover Northwest's cost of service and
result in a revenue deficiency of approximately $119.1 million.
In compliance with 18 CFR 154.7(aX6), the following table compares the cost of

service, rate base and throughput underlying this filing with the same information
underlying the most recently Commission-approved just and reasonable rates. For "the
last rates found just and reasonable by the Commission," Northwest is using the cost of
service, rate base and throughput in the Settlement Agreement approved in Docket No.
RP96-367, and increasing such amounts by the incrementally priced expansion projects
and cost of service projects which were certificated by the Commission after the March 1
1997 effective date of the Oocket No. RP96-367 rate case.

This Filing $441,4 78 087 506,923 947 801 353,958
The cost of service underlying this filing utilizes a base period for the twelve months
ended March 31, 2006, adjusted for known and measurable changes through December
31, 2006, which, as shown above, results in an increase in Northwest's cost of service of
approximately $128.2 million4/ over the cost of service underlying the last rates found just
and reasonable by the Commission. The major reasons for the increased cost of service
are:
a) an increase of approximately $12.1 million included in the Certificate Application
filed in Docket No. CP06-45 for the incrementally priced Parachute Lateral Project,
which is anticipated to be placed in service on November 1 , 2006;
11 Excludes approximately $2.3 million cost of service and approximately $8.7 million rate base
related to the Tumwater and Olympia projects since Northwest was fully reimbursed for these
two projects following the effective date of the Docket No. RP96-367 settlement.
The Cost of Service Projects include the Berwick (Docket No. CPO3-196), Centralia (Docket
No. CPO3-196), and Elmore (Docket No. CPO2-240) laterals and the Columbia Gorge 1999
Expansion (Docket No. CP98-554). The cost of service and rate base for Berwick, Centralia and
Elmore are updated to reflect the current annual cost of service calculations pursuant to Section
21 of the General Tenns and Conditions of Northwest's Tariff.
31 Includes the cost of service, rate base, and throughput related to the proposed incrementally
priced Parachute Lateral Project.
41 This amount is higher than the revenue deficiency shown on Statement G of $119.1 million
due primarily to the $12.1 million cost of service associated with the Parachute Lateral, partially
offset by other minor differences, including throughput, and minor cost variances associated with
each calculation.

b) an increase of approximately $61.6 million included in the Certificate in Docket No.
CP05-32 for the rolled-in Capacity Replacement Project, which is anticipated to be
placed in service on November 1 , 2006;
c) an increase of approximately $21.8 million included in the Certificate in Docket No.
CP01-438 for the rolled-in Rockies Displacement Project, net of approximately
$16.7 million in escrow funds which were used to partially offset the capital cost of
the project;
d) an increase of approximately $7.1 million included in the Certificate in Docket No.
CP02-4 for the rolled-in portion of the Sumas-Chehalis and Columbia Gorge
displacement facilities constructed as part of the Evergreen Expansion Project;
e) an increase of approximately $16.9 million related to the increase in the rate of
return and associated income taxes (i.e. pre-tax return) on the approximately $1.507
billion rate base included in this filing;
f) an increase of approximately $13.9 million related to operation and maintenance
expenses, including administrative and general expenses, ("O&M"), in addition to
the O&M costs included in the total project costs enumerated above, including
approximately $5.9 million associated with a required accounting change to expense
pipeline assessment costs; and
g) a reduction of approximately $5.2 million related to the net effect of various other
changes reflected in this filing, including normal rate base decline as a result of
depreciation partially offset by additional reliability and integrity-related
expenditures.
II. Cost of Service
The cost of service in this filing, as indicated above and supported by the Statement
P testimony of various Northwest witnesses submitted with the filing, is $441,478,087which consists of the following cost components:
O&M Expenses
Depreciation and Amortization
Taxes Other Than Income Taxes

Northwest is requesting an overall after tax rate of return of 10.96 percent (15.47percent pre-tax), including a rate of return on equity of 13.6 percent. Consistent with
Commission policy, Northwest has used its projected capital structure as of the end of the
test period comprised of debt capital of 45 percent and common stock equity of 55 percent.
The evidence in this rate proceeding supports a depreciation rate of 2.93 percentapplied to transmission plant (exclusive of the facilities associated with the EvergreenExpansion 15 and 25 year contracts and the Cost of Service Projects), and a net negative
salvage rate of 0.94 percent for a combined rate of 3.87 percent. However, Northwest is
making a market adjustment to its net negative salvage rate as applied to such
transmission plant to reduce it to 0.31 percent, but only to the extent that the combination
of depreciation and net negative salvage rates would otherwise exceed 3.24 percent.Northwest has proposed certain other changes to the depreciation and net negativesalvage rates as shown on Statement H-2 page 2 of this filing.
III. Other Proposed ChanQes
Northwest is proposing in this proceeding a two-part straight-fixed variable ("SFY'rate design for the Rate Schedule TF-1 (Large Customer) rates (but will maintain the
levelized rate methodology for the Evergreen Expansion shippers and a one-partvolumetric rate for Rate Schedule TF-1 (Small Customer)). While SFV rate design is a
change from the rates that were implemented in the settlement of Northwest's last rate
case in Docket No. RP96-367, SFV rates are consistent with the Commission s directivesin Order No. 636 and with the rate design the Commission approved in Northwest's last
litigated rate proceeding in Docket No. RP95-409.
The rate for service under Rate Schedule LS-21 associated with interruptible storage
service at Northwest's Plymouth LNG storage facility is modified to provide for the inclusion
of liquefaction and vaporization charges. Currently, a shipper under Rate Schedule LS-only pays a daily volumetric inventory charge. Northwest proposes to revise Rate
Schedule LS-21 to reflect liquefaction and vaporization charges similar to such chargesunder Rate Schedules LS-1 and LS-2F.
IV. Tariff Sheets - 18 CFR 154.7(a)(5)
Appendix A contains the following revised tariff sheets which are being submitted in

Proposed Sheet Nos. 5 through 8.1 are submitted to revise Northwest's
Statement of Rates in its tariff to reflect the overall increase in Northwest's jurisdictionalrates and to reflect new liquefaction and vaporization rates under Rate Schedule LS-
on Sheet No. 8.
Sheet No. 91 is submitted to revise Rate Schedule LS-21 to provide for liquefactionand vaporization charges associated with interruptible storage services at Northwest'sPlymouth LNG storage facility. Sheet No. 91-A is submitted due to pagination.

Northwest's certificate application in Docket No. CP06-45 for the construction and
operation of the Parachute Lateral project anticipates an in-service date for the Parachute
Lateral prior to January 1 , 2007 and the anticipated costs associated with the Parachute
lateral project are reflected in the test period adjustments. Pro forma tariff sheets includedin the certificate filing include recourse rates associated with service on the Parachute
Lateral, and Northwest incorporates these pro forma tariff sheets by reference in the instant
filing. Since Northwest is requesting an effective date of August 1 , 2006 for the proposedtariff sheets submitted in the instant filing, the recourse rates for the Parachute Lateral
project are not reflected on the proposed tariff sheets. Therefore, pro forma Sheet No.al.sois submitted to show both the rates on proposed Thirty-First Revised Sheet No.
submitted herewith and the rates for the Parachute lateral project under the newParachute lateral Rate Schedules TFl-1 and TIL-1. When Northwest submits a motion
December 2006 to move into effect on January 1 , 2007 the tariff sheets in the instant filing,
following an anticipated five month suspension period, Northwest will file Substitute Thirty-First Revised Sheet No.5 to include the Parachute lateral rates.
Proposed Effective Date and Waiver Request - 18 CFR 154.7(a)(3), (6), (8) and (9)
Pursuant to Section 154.7(a)(9) ofthe Commission s regulations, Northwest herebymoves that the proposed tariff sheets be made effective August 1 , 2006, or at the end ofany suspension period which may be imposed by the Commission. Although Northwest
has requested an effective date of August 1 , 2006 , Northwest anticipates this filing will be
suspended for the full five month period, with an effective date of January 1, 2007. For thereasons discussed above, Northwest requests that a waiver of Section 154.7(a)(9) or154.206 of the Commission s regulations be granted, as necessary, and that thesuspension order include a statement that Northwest may file Substitute Thirty-First
Revised Sheet No.5 reflecting the anticipated Parachute lateral rates as shown on pro
forma Sheet No.5 when Northwest files a motion, pursuant to Section 154.206 of theCommissions regulations, to place the suspended rates into effect.

Re:Gas Transmission Northwest Corporation
Docket No. RP06-
Dear Secretary Salas:
Pursuant to Section 4(e) of the Natural Gas Act, as amended
/ ("
NGA") and Subpart D
of Part 154 of the regulations of the Federal Energy Regulatory Commission ("FERC" or
Commission / Gas Transmission Northwest Corporation ("GIN") hereby submits for filing
and acceptance the revised tariff sheets listed on Appendix A to be included in its FERC Gas
Tariff, Third Revised Volume No. I-A. The tariff sheets are proposed to become effective on
August 1, 2006. GIN anticipates, however, that the rates proposed herein will be subject to a
five-month suspension period and placed into effect on January 1 2007.
Statement of Nature. Reasons and Basis
The purpose of this filing is to restate GIN's rates for service on its interstate
transportation system. GIN's system extends approximately 612 miles from the International
Boundary at Kingsgate, British Columbia, to the Oregon-California border, where
interconnects with Tuscarora Gas Transmission Company and Pacific Gas & Electric Company.
GIN utilizes this pipeline to provide firm and interruptible transportation service to numerous
shippers serving the Pacific Northwest, California, and Nevada markets. GIN also interconnects
with facilities of Northwest Pipeline near Spokane and Palouse, Washington, and Stanfield
Oregon.
GIN's current rates for service were established more than 10 years ago by settlement in
Docket No. RP94-149.Since that time, the market in which GIN operates has undergone

significant, fundamental changes, including an increase in pipeline capacity into GTN's major
market in California as well as an increase in pipeline capacity out of GTN's major supply area
in the Western Canada Sedimentary Basin ("WCSB"). The changing competitive landscape has
left GTN with substantial unsubscribed capacity as a result of capacity turnback and shipper
defaults, and GTN has been forced to drastically discount the price of capacity to meet
competitive demands. As further described in the testimony filed herein, GTN anticipates that
during the test period, it will have approximately 450 000 Dth per day of unsubscribed long-term
capacity as the result of capacity turnback and/or defaults by customers. Also, as described in
the testimony, GTN does not anticipate that it will be able to sell its unsubscribed capacity at or
near GTN's tariff rate for the foreseeable future. In fact, for 290 days of the base period, GTN'
capacity was worth less than zero the cost of transporting gas on GTN and upstream
pipelines exceeded the difference between the price of gas in the supply and market areas.
As a result of the turnback of capacity and persistently poor market conditions, GTN is
compelled to file to increase its rates to reflect the heightened risks it now faces and to allow
GTN a fair opportunity to recover its costs and earn a fair return. To address the unique risks
presented to the pipeline and its shippers by this level of capacity turnback and default, GTN
proposes that it share with its shippers the costs associated with unsubscribed mainline capacity
on a 10 percent/90 percent basis, respectively. GTN's proposal honors the Commission
objective that l,ipelines not shift 100 percent of the costs associated with turnback capacity to
their shippers.
To the extent that GTN's efforts to remarket its unsubscribed capacity are successful
GTN proposes to share revenues generated from such unsubscribed mainline capacity sales with
its shippers on a 25 percent/75 percent basis, respectively, after all costs allocated to long-term
firm, short-term firm, seasonal and interruptible capacity services have been recovered. GTN
will share revenues associated with mainline capacity sales regardless of their source, be it from
long-term fIrm, short-term firm, seasonal, or interruptible capacity sales. Therefore, maximum
rate, long-term firm shippers' ultimate cost responsibility will be reduced by the sale of GTN'
unsubscribed capacity. By allowing GTN to retain 25 percent of the revenue from unsubscribed
capacity sales, GTN will have an ongoing incentive to sell its unsubscribed capacity for the
benefit of itself and its shippers.
GTN is also proposing a series of other changes designed to increase recovery of costs
and reduce the burden on long-term firm shippers, including charging a market-based rate for
full-haul interruptible transportation; implementing hub service rates that are similar to a 100
percent load factor interruptible transportation rate; and implementing a flexible service proposal
designed to allow increased recovery of revenue from short-haul services. These proposals are
addressed in greater detail below and in the testimony. Again, these services will inure to the
benefit oflong-term firm shippers through GTN's revenue sharing proposal.
The enclosed Statement P, in Volumes 3 of this filing, contains the prepared direct
testimony and exhibits supporting GTN's proposed rate increase and tariff changes. A list of

Barry E. Sullivan Consistency of GTN's market-based IT rate
proposal with Commission policy.
Reasons for Proposed Rate Increase
GTN's cost-of-service and rate calculations are based upon the costs and throughput
levels for the base period (twelve months ended March 31, 2006) as adjusted for known and
measurable changes through the test period ending December 31 , 2006. As a result of the
changes proposed herein, GTN's maximum recourse full-haul unit rate for service under Rate
Schedule FTS-1 will increase from $0.262787 per Dth to $0.449854 per Dth. However, as
discussed above, under GTN's revenue sharing mechanism, the rate paid by long-tenn finn
shippers could be significantly reduced if GTN is successful in remarketing unsubscribed
capacity.
In compliance with section 154.7(a)(6) of the Commission s regulations, the following
table compares the cost-of-service, rate base, and throughput contained in this filing with the
same infonnation underlying GTN's last rates found to be just and reasonable by the
Commission:

Mainline Rate Base

The proposed rates also incorporate an increase in return on equity, reflecting the
increased business and financial risks GTN now faces. As detailed in the testimony of GTN
Witness Amy Leong, GTN's proposed rates include an overall cost of capital of 11.33 percent.
Witness Leong establishes GTN's overall cost of service for the twelve-month base period
ending March 31 , 2006, adjusted for known and measurable changes for the test period ending
December 31 , 2006, as $303.5 million. This cost of service is based on GTN's actual capital
structure of37.01 percent debtJ62.99 percent equity and a transmission depreciation rate of2.
percent. GTN Witness Leong supports the use of GTN's own capital structure, which confonns
to FERC's policy in that GTN issues its own non-guaranteed debt, has its own debt ratings
separate from its parent, and has a common equity ratio in line with others previously approved
by the Commission.
In addition, GTN Witness Paul R. Moul supports an appropriate return on common
equity in the range of 13.0 to 15.0 percent. Based upon the investment risks unique to GTN, as
detailed in the testimony of GTN Witnesses Moul, Steven H. Levine, and Leslie Ferron-Jones
GTN has justified a rate of return on equity of 14.5 percent.

GIN Witnesses demonstrate that GIN has above-average business risk relative to the
relevant pipeline proxy group. GIN faces above-average supply risk due to its heavy
dependence on gas supplies sourced from the WCSB, a basin where production has flattened out
and is projected to remain flat or decline in the coming years. GIN also faces above-averagemarket risk in its primary destination market in California because WCSB gas supplies
transported to California via GIN compete with Rocky Mountain and San Juan gas suppliestransported to California via numerous pipelines. Indeed, since 2001 , there have been several
expansions of pipeline capacity to California, which have resulted in excess interstate pipeline
capacity to the state.
As a result of the competitive conditions in GIN's supply and market areas, GIN'pipeline capacity has been devalued significantly. GIN Witness Ferron-Jones describes howGIN has had difficulty selling its unsubscribed capacity even at sharply discounted rates due to
these conditions.
As supported by GIN Witnesses Edward H. Feinstein, Walter W. Haessel and Dan A.
King, GIN's rates also reflect an increase in the depreciation rate of GIN's transmission plant to
76 percent and the establishment of a negative salvage rate of 0.74 percent.
Other Rate-Related Proposals
Market-Based, Full-Haul IT Rate Proposal
Consistent with Commission policy and Commission cases approving or otherwise
addressing market-based rates for transportation fl.GIN is proposing to charge market-basedrates for full-haul interruptible transportation ("IT") service from the International Boundary

service from Kingsgate to Malin, and thus the Commission can appropriately approve GTN'
request to charge market-based rates for such service. Just as importantly, GTN is not filing for
authority to charge market-based rates for IT services at any other delivery points on its system.
After careful consideration, GTN has determined that customers at these other receipt and
delivery points do not have the same quality of good alternatives available to them. GTN will
continue to provide all other customers (at all other delivery points) with IT service at a capped
cost-based IT tariff rate.
Roll-In of 1998 and 2002 Expansion Projects
GTN is proposing to roll in the costs associated with the 1998 and 2002 expansions. The
1998 Expansion benefits from de minimis capital costs of only $6 million and easily meets the
roll-in threshold of the Commission s 1995 Policy Statement / even after taking into account all
changed circumstances. The rate impact of rolled-in treatment for the proposed expansion is
below the 5 percent threshold established by the Commission. GTN's roll-in analysis
demonstrates that there are rate reductions and system benefits associated with the 1998
Expansion.
The 2002 Expansion meets the roll-in test as set forth in the 1999 Policy Statemen1.
Consistent with Commission policy,/ GTN calculated a rolled-down, stand-alone rate for the
2002 Expansion, utilizing all maximum rate post-expansion long-term finn capacity sales and
permanent capacity releases, with the exception of those expected to terminate or default during
the test period. The resulting rolled-down 2002 Expansion rate is lower than the filed-for
mainline system rate without the 2002 Expansion costs and volumes. As such, the 2002
Expansion qualifies for rolled-in treatment under the 1999 Policy Statement because with roll in
existing shippers will not subsidize the expansion. GTN is also proposing to roll in fuel costs
associated with the 2002 Expansion. GTN demonstrates that pipeline capacity sales and
permanent releases since the inception of the roll-down mechanism warrant a rolling in of the
2002 Expansion fuel costs. Rolling-down the overall incremental fuel rate yields a current rate
expressed on a full-haul basis, of 1.14 percent, well below the roll-in threshold of 2.45 percent.
Flexible Services Rate Proposal
GTN is proposing to facilitate the recovery of unsubscribed capacity costs by
allowing GTN to apply higher rates to new contracts for services not sold on an annual, uniform
MDQ basis. Such services would include seasonal long-term firm, variable MDQ long-tenn
firm, short-term finn and interruptible transportation other than full-haul (collectively referred to
as "flexible services
).
GTN proposes to set the maximum rate for flexible services equal to 2.
times the maximum reservation component of the recourse rate that applies to long-tenn finn
uniform MDQ shippers, plus the delivery component applicable to long-term firm, unifonn

MDQ shippers. These flexible service rates can be assessed at any time during the year and
revenues nom flexible services will be shared on an annual basis to the extent that overall
pipeline revenues for mainline service exceed what would have been collected had the maximum
recourse rates for long-term, uniform MDQ shippers applied to all mainline volumes transported
during the annual period. GTN proposes that revenues above this threshold be shared among
GTN and its shippers on a 25 percent/75 percent basis, consistent with the revenue sharing
percentage GTN is proposing for unsubscribed capacity sales.
Hub Service Rates
Consistent with Commission precedent j GTN is also proposing to charge a
postagestamp rate for hub services which is similar to a 100 percent load factor IT rate. By
approving this proposal, the Commission will level the playing field for pipelines serving
western markets by allowing GTN the opportunity to charge similar rates for similar services.
Summary of Proposed Tariff Chan!!es
GTN is also proposing to implement the following tariff changes reflected on the revised
tariff sheets in Appendix A, to be effective August 1 , 2006:
Revised Base Rates
As explained above, GTN is updating its cost-of-service and proposing to increase its
base transportation rates (maximum recourse rates) for Rate Schedule FTS-l. In addition, GTN
is seeking authorization to charge market-based rates for full-haul interruptible transportation
service under Rate Schedule IT nom one receipt point (Kingsgate) to one delivery point (Malin).
As noted, GTN is also requesting authorization to implement a flexible service rate proposal that
will allow GTN to set the maximum rate for new sales of seasonal long-term firm, variable MDQ
long-term firm, short-term firm, and interruptible transportation other than full-haul at levels
higher than their respective maximum recourse rates, subject to a cap of 2.5 times the maximum
reservation component of the recourse rate that applies to long-term firm, uniform MDQ
shippers, plus the delivery component applicable to such long-term firm, uniform MDQ shippers.
Creditworthiness
As detailed in the testimony of GTN Witness Kenneth W. Nichols, GTN proposes to
make four tariff changes related to credit provisions:
First, GTN proposes to modify General Terms and Conditions ("GT&C") ~ 18.1(e) to
allow GTN to consider a shipper s credit quality when evaluating bids and awarding capacity in
an open season for long-term firm capacity based on specific, objective criteria that will be
posted prior to the commencement of each open season. As explained by GTN Witness Nichols
this change is necessary given GTN's unique experience with non-creditworthy shippers, and is

also consistent with FERC's Policy Statement on Creditworthiness Issues for Interstate Natural
Gas Pipelines. il
Second, GTN proposes to modify GT&C ~ 18.3(A)(2)(b) and ~ 18.3(D)(3) of its Tariff to
give GTN the discretion to determine whether to allow a shipper to replace its original credit
assurance with an alternative assurance. This proposal would prevent a shipper from using a
superior form of credit assurance to secure capacity in an open season and then substituting an
inferior form of security thereafter.
Third, GTN proposes to clarify GT&C ~ 18.3(A)(2)(b)(i) and ~ 18.3(D)(3)(a) to ensure
that GTN has the authority to request additional assurances when a shipper provides GIN with a
guarantee and the guarantor has become noncreditworthy or no longer has a sufficient credit
limit.
Fourth, GTN is proposing to eliminate its current strict "10 percent of tangible net worth
test" for establishing shipper credit limits in GT&C ~ 18.3(A)(2)(b) and to replace it with a more
flexible approach that considers a shipper s specific circumstances in determining credit limits.
Reservation of Capacity for Future Expansions
GTN is proposing to revise GT &C ~ 32 to permit GTN to reserve unsubscribed firm
capacity, or capacity under existing or expiring firm transportation agreements that are not
subject to the right of flIst refusal ("ROFR"), for use in connection with a future expansion
project. GTN will only be permitted to reserve capacity for a future expansion project for which
an open season has been held or will be held within one year of posting the capacity as reserved.
Capacity may only be reserved for up to one year prior to GTN's filing a certificate application
for the proposed expansion, and thereafter until the expansion is placed into service. GIN
submits that its proposed tariff revisions with respect to the reservation of capacity for future
expansions are consistent with the caRacity reservation tariff provisions that the Commission hasapproved for several other pipelines.
Open Seasons for Expansion Capacity and ROFR Capacity
GTN Witness Roscher describes how GTN's currently-effective ROFR procedures have
exposed GTN and it long-term shippers to the risk of prospective capacity turnback. For
example, in 2001 an open season for ROFR capacity generated contract extensions of 2 to 5
years while contemporaneous open seasons for GTN's 2002 Expansion Project generated
binding bids for terms ranging from 10 to 52 years.GTN awarded the expansion capacity to

two shippers for contract terms of 52 and 40 years./ According to Mr. Roscher, shippers and
potential shippers have been reluctant to bid on ROFR capacity because of the uncertainty
inherent in the ROFR shipper s right to retain the capacity by matching the highest bid.
In order to promote allocative efficiency, rationalize demand for expansion capacity with
existing capacity and reduce the risk of prospective capacity tumback, GTN is proposing to add a
new ~ 33.11 to its ROFR procedures that will permit GTN to hold one open season for an
expansion project and a shipper s ROFR capacity when GTN has announced an expansion
project and a shipper has notified GTN of its intent to exercise its right of first refusal. Under the
proposed ~ 33., in order to continue to receive transportation service following the expiration
of its contract term, a ROFR shipper may be required to match the lowest acceptable bid that
meets the minimum terms and conditions of the expansion open season.
GTN submits that this matching requirement is consistent with the Commission
allocative efficiency principle that holds that pipeline capacity should be allocated to shippers
that value the capacity most as reflected by the NPV of their bids. If an expansion shipper places
greater value on the existing capacity than the ROFR shipper, then the existing capacity should
be used to satisfy this new demand. By satisfying new demand with existing capacity, GTN'
proposal also rationalizes capacity by reducing the pipeline s need to construct additional
capacity. Finally, GTN's proposal would benefit GTN and its shippers by reducing the risk of
prospective capacity tumback. Allocating ROFR capacity and expansion capacity in one open
season would mitigate the risk of future capacity tumback by ensuring that the longest possible
term for the capacity is obtained.
Finally, GTN submits that its proposal to require the ROFR shipper to match the
minimum terms and conditions in the expansion open season is consistent with Commission
precedent. In Kern River Gas Transmission Co., for example, the Commission relied on its
earlier decision in Tennessee Gas Pipeline Co. to find that "if a pipeline has already announced
an expansion project, the Commission will allow the pipeline to impose the same minimum
terms and conditions on the posting of unsubscribed capacity that it anticipates it will impose in
the future expansion project open season."lQ/ Thus, in these cases the Commission has endorsed
the concept that, when the pipeline has announced an expansion project, in allocating expired
capacity, the pipeline may impose the same minimum terms and conditions that it will use to
allocate the expansion capacity.
ROFR Notice Period When Expansion Project is Proposed
Under the ROFR procedures set forth in GT&C ~ 33, in order to exercise the ROFR, a
shipper must notify GTN one year prior to the primary election date whether it elects to

terminate or not to terminate its service agreement. If the shipper elects not to terminate its
contract, then the ROFR process will be triggered and the shipper will be permitted to retain its
capacity if it agrees to match any acceptable bid that may be received by GTN. In light of its
proposal to rationalize the allocation of ROFR capacity with allocation of expansion of capacity,
GTN is also proposing to revise its ROFR procedures to provide that, when GTN has proposed
an expansion the sizing of which could be affected by the shipper s decision on whether or not to
exercise its ROFR to continue service, GTN may notify a shipper that its election to terminate or
not to terminate its service agreement must be provided up to 36 months prior to the expiration
date of the shipper s term of service. GTN's proposed language with respect to the 36-month
notice requirement is virtually identical to language that the Commission has approved for
Northern Border Pipeline Company.

NEWS RELEASE

CUSTOMER NOTICE
NEWS RELEASE Contact: Mike Huntington
Vice President
Marketing & External Affairs
(208) 377-6059August 16, 2006
Today, Intermountain Gas Company ("Intermountain ) filed its annual purchased gas cost adjustment application
with the Idaho Public Utilities Commission ("IPUC"). This type of application is filed each year to ensure that the costs that
Intermountain is incurring on behalf of its customers are properly reflected in its sales price. In its application
Intermountain requests permission to adjust its prices to reflect the prices of natural gas supplies that it expects to incur.
William C. "Bill" Glynn , President of Intermountain Gas Company, said
, "
Despite increases in some other energy
prices like crude oil that has increased 30% during the past year, the Company expects to be able to manage its natural
gas purchases such that it will not need to raise customer prices for this next winter season." Commenting further Glynn
said
, "
The forces behind this expectation include the increase in natural gas production resulting from additional drilling,
the return of Gulf Coast production which was shut-in from hurricane Katrina, and purchasing and pricing strategies the
Company has employed , including the use of significant summer storage injections for winter deliveries.
Glynn , however, went on to say, "We are pleased to be able to offer this additional price stability, however
Intermountain continues to urge all its customers to be conscious of their energy usage and use it wisely. Helpful tips on
ways to do that and how to request government payment energy assistance are provided through bill inserts and on the
Company s website (www.intqas.com). We also have a number of programs to help our customers level out their energy
bills over the year, and stabilize the potential impact that cold weather will have during periods of higher natural gas
usage.
If approved as filed, all residential and commercial customer s unit prices will be essentially unchanged for natural
gas used this next year and the Company s total net revenue will decrease by approximately $1.6 million (.5%). The
proposed effective date is October 1 2006. This proposal is subject to public review and approval by the IPUC. A copy
of Intermountain s application is available at the offices of both the Idaho Public Utilities Commission and the Company.
