IrVrpnuOtxrant GAS CoMPANY,S APPLICATIoN . 3
Intermountain's properties in these locations consist of transmission pipelines, liquefied
natural gas storage facilities, compressor stations, distribution mains, services, meters and
regulators, and general plant and equipment.
II.
With this Application, Intermountain seeks to pass through to each of its customer classes
changes in gas related costs resulting from: 1) costs billed to Intermountain from firm transportation
providers including Northwest Pipeline LLC ('Northwest" or ooNorthwest Pipeline"),2) an increase
in Intermountain's Weighted Average Cost of Gas ("WACOG"), 3) an updated customer allocation
of gas related costs pursuant to the Company's Purchased Gas Cost Adjustnent ("PGA") provision,
4) the inclusion of temporary surcharges and credits for one year relating to natural gas purchases
and interstate transportation costs from Intermountain's deferred gas cost accounts, 5) benefits
resulting from Intermountain's management of its storage and firm capacrty rights on various
pipeline systems, 6) benefits associated with the sale of liquefied natural gas from the Company's
Nampa, Idaho facility, 7) a portion of the costs accrued related to Intermountain's Case No. INT-G-
16-02 General Rate Case and, 8) the recovery of deferred in-person customer payment fees.
Intermountain also seeks to eliminate the temporary surcharges and credits included in its current
prices dwing the past 12 months, pursuant to Case No. INT-G'20-05. If approved, these changes
would result in a price increase to Intermountain's RS, GS-l, LV-I, and T-4 customers and a price
decrease to Intermountain's T-3 customers.
These price changes are applicable to service rendered under rate schedules affected by and
subject to Intermountain's PGA, initially approved by this Commission in Order No. 26109, Case
No. NT-G-95-1, and additionally approved through subsequent proceedings.
INrpRNaouNrrlnq Ges CorrlpANy's AppltcertoN - 4
IIL
The Commission approved the current temporary prices, and prices related to the cost of
gas, in Order No. 34797, Case No. INT-G-20-05.
Iv.
Intermountain's proposed prices incorporate all changes in costs relating to the
Company's firm interstate transportation capacity including, but not limited to, any price changes
or projected cost adjustments implemented by the Company's pipeline suppliers which have
occurred since Intermountain's PGA filing in Case No. INT-G-20-05. Exhibit No. 4, which
contains pertinent excerpts from applicable pipeline tariffs, is attached and incorporated by
reference.
Suppliers upstream of Northwest Pipeline filed a net decrease to rates. In addition, the
discount to full rate prices expired on several upsfream contracts resulting in a small cost increase.
The net price decrease resulting from these upstream supplier price changes of $451,978 is included
on Exhibit No. 5, Lines 5 and 6. Exhibit No. 5 is attached and incorporated by reference.
v.
Intermountain continues to contract a variety of natural gas storage assets on Northwest
Pipeline's system as well as with Dominion Energy Questar Pipeline, LLC ("Dominion"). In
addition to providing operational reliability, these storage contracts can provide significant price
stability to customers.
Furthermore, Intermountain continues to effectively manage its nafural gas storage assets
at Northwest's Jackson Prairie and Dominion's Clay Basin storage facilities. As shown on Line
20 of Exhibit No. 5 and supporting documents, Intermountain's management of these storage
assets resulted in $2.3 million in savings.
IITTEnUoITNTAIN GAS CoN,PANY, S APPLICATIoN - 5
Exhibit No. 5, Lines 7 through 20, details the proposed changes to Intermountain's prices
resulting from lntermountain' s storage contracts.
vI.
The WACOG reflected in Intermountain's proposed prices is $0.26000 per therm, as shown
on Exhibit No. 5, Line 22, Col. (f1. This compares to $0.21699 per therm currently included in the
Company's tariffs.
Intermountain continues to source a major portion of its physical gas supply from AECO in
the Province of Alberta, Canada as it remains the lowest cost term commodity gas available to the
Company. Although AECO gas continues to be the lowest priced gas supply, the price continues to
increase. Several factors have confibuted to this increase. First, economies in Canada and the U.S.
have continued to rebound from the worldwide pandemic, resulting in an increase in demand for
natural gas. At the same time, natural gas producers have focused more on shareholder returns
versus production growth resulting in very measured, incremental spending on drilling. Second, the
more rapid recovery of natural gas demand versus supply has led to much lower storage inventories
than the previous year. The result is increased pressure on natural gas prices as the market searches
for supplies to fill storage ahead of the upcoming winter heating season. Finally, the unusually high
temperatures across the West this summer coupled with the significant drought and resulting lower
water year have resulted in an expectation of increased natural gas fned electric demand for the rest
of the swnmer and early fall. These combined factors leading to more rapidly increasing demand for
natural gas in the face of measured growth in supply have put increasing upward pressure on the
commodity price for natural gas as reflected in the Company's WACOG.
To help offset some of the volatility in the market, the proposed WACOG includes benefits
to Intermountain's customers generated by the Company's management of its significant natural gas
IvrgRuotxrenq Gls CoMpAl.Iy's AppllcenoN - 6
storage assets. Because gas added to storage is procured during the summer season when prices are
traditionally lower than during the winter, the cost of Intermountain's storage gas is normally less
than what could be obtained on the open market in winter months. Additionally, in an effort to
further stabilize the prices paid by our customers during the upcoming winter period, Intermountain
has entered into various fixed price agreements to lock-in the price for portions of its underground
storage and other winter "flowing" supplies.
Intermountain believes that the WACOG proposed in this Application, subject to the effect
of actual supply and demand and based on current market conditions, provides today's most
reasonable forecast of gas costs for the202l -2022 PGA period. Intermountain will employ, in
addition to those fixed price agreements already in place, cost effective price arrangements to
further secure the price of flowing gas embedded within this Application when, and if, those pricing
opportunities materialize in the marketplace.
Intermountain believes that timely natural gas price signals enhance its customers' ability to
make informed and appropriate energy use decisions. The Company is committed to alert
customers to any significant impending price changes before their winter natural gas usage occurs.
By employing the Company's Energy Efficiency programs, customer mailings, the Company's
website, and various media resources, Intermountain will continue to educate its customers
regarding the wise and effrcient use of natural gas, billing options available to help manage their
energy budget, and any pending natural gas price changes.
YII.
Pursuant to the Commission's Order in Case No. INT-G-20-05,Intermountain included
temporary credits in its October 1,2020 prices for the principal reason of passing back to its
customers deferred gas cost benefits. Lne27 of Exhibit No. 5 reflects the elimination of these
brrenuOtxrent Gas CoMPAT.IY'S APPLICATIoN - 7
temporary credits.
In summary, Exhibit No. 5 outlines the price changes in l) Intermountain's base rate gas
costs as previously described,2) its rate class allocation, and 3) net adjustnents to temporary
surcharges or credits flowing through to Intermountain's customers.
vIIL
Under the Company's PGA taritr, Intermountain's proposed prices will be adjusted for
updated customer class sales volumes and purchased gas cost allocations. Intermountain's proposed
prices include a gas transportation cost adjustnent pursuant to these PGA provisions, as outlined on
ExhibitNo. 6, Llrire25. The price impact of this adjustment is included on ExhibitNo. 5, Line 28.
The Gas Transportation Cost resulting from the adjustment plus the annual difference in demand
charges from Exhibit No. 5, Lines I -20, Col. (h) is shown on Exhibit No. 6, Line29. Exhibit No. 6
is attached and incorporated by reference.
IX.
Intermountain proposes to pass through to its customers the benefits that will be generated
from the management of its tansportation capacity, totaling $6.4 million as outlined on ExhibitNo.
8. These benefits include credits generated through releases of a portion of Intermountain's firm
capacity rights on Norlhwest Pipeline as well as credits generated from releases of Intermountain's
upsteam pipeline capacity. Intermountain proposes to pass back these credit amounts via the per
therm credits, as detailed on Exhibit No. 8 and included on Exhibit No. 7,Line 1. Exhibit Nos. 7
and 8 are attached and incorporated by reference.
INTERMoT]NTAIN GAS CoIvPANY' S APPLICATTON - 8
x.
Intermountain proposes to allocate defened gas costs from its Account No. 191 balance to
its customers through temporary price adjustrnents to be eflective during the l2-month period
ending September 30,2022, as follows:
1) Intermountain has deferred fixed gas costs in its Account No. l9l. The credit amount
shown on Exhibit No. 9, Line 7, Col. (b) of $6.0 million is attributable to a true-up of the collection
of interstate pipeline capacity costs, the true-up of expense issues previously ruled on by this
Commission, and mitigating capacity release credits generated from the incremental release of
Intermountain's pipeline capacity. Intermountain proposes to true-up these balances via the per
therm debits and credits, as detailed on ExhibitNo. 9 and included on ExhibitNo. 7, Line2. Exhibit
No. 9 is attached and incorporated by reference.
2) Intermountain has also defened in its Account No. 191 a variable gas cost debit of $9.3
million, as shown on Exhibit No. 10, Line 2, Col. (b). This defened debit is attributable to
Intermountain's variable gas costs since October 1,2020. Intermountain proposes to collect this
balance via a per therm debit, as shown on Exhibit No. 10, Line 4, Col. (b) and included on Exhibit
No. 7, Line 3.
3) Finally, Intermountain has deferred in its Account No. l9l defened gas costs related to
Lost and Unaccounted for Gas as shown on ExhibitNo. 10, Lines 5 through 26,Col. (b). This
deferral results in a per therm decrease to Intermountain's customers, as illustrated on Exhibit No.
10. This per therm decrease is included on Exhibit No. 7, Line 3. Exhibit No. 10 is attached and
incorporated by reference.
INrpRvoLNranq Ges CoN,pANy's AppllcerloN - 9
xr.
Pursuant to Commission Order No. 32793, Case No. INT-G-13-02, Intermountain has
deferred in its Account No. l9l gas cost credits associated with sales of liquefied natural gas at its
Nampa, Idaho facility. Intermountain proposes to pass back this $0.7 million sales credit as outlined
on Exhibit No. I 1, Line 7 and shown on Exhibit No. 7, Line 4. Exhibit No. I I is attached and
incorporated by reference.
xII.
As directed in Commission Order No. 33887, Case No. INT-G-17-05, Intermountain
established a regulatory asset to amortize over a five-year period $378,614 related to external
General Rate Case costs associated with Case No. INT-G-I6-02. Exhibit No. 12 also includes a
fue-up of September 30, 2020 remuning balances previously ruled upon by this Commission.
Exhibit No. 12 summarizes the amortization and true-up of these costs which are included on
Exhibit No. 7, Lines 5 and 6. Exhibit No. 12 is attached and incorporated by reference.
xIII.
In Commission OrderNo.34099, CaseNo.INT-G-18-01, the Company was directedto defer
and later collect through the PGA the fees associated with in-person customer payments at third party
vendors. This authorization was extended in Order No. 35047, Case No. INT-G-21-02. Exhibit No.
13 summarizes the customer class surcharges associated with these previously deferred costs which
are included on Exhibit No. 7,Line 7. Exhibit No. 13 is attached and incorporated by reference.
xrv.
Intermountain has allocated the proposed price changes to each of its customer classes based
upon the Company's PGA provision. However, a straight cents per therm price change was not
utilized for the LV-l tariffas no fixed costs are currently recovered in the tail block of the LV-l
INTERMoTINTAIN GAS COITIPANY'S APPLICATION - IO
tariff. The proposed changes in the WACOG, and variable deferred debits and credits as outlined
on Exhibit No. 7, Lines 3 through 7, are applied to all three blocks of the LV-l tariff. However, all
adjusfrnents relating to fxed costs are applied only to the first two blocks of the LV-l tariff.
xv.
As outlined on ExhibitNo. 2, Page l, Lines 21 through 29,the T-3 and T-4 tariffs include
the following adjustrnents: a) the removal of existing temporary price changes, and b) the inclusion
of proposed temporary price changes from ExhibitNo. 7. The net change from these
aforementioned adjustments result in a rate decrease for the Company's T-3 customers and a rate
increase for T-4 customers.
xvl.
The proposed price changes herein requested among the classes of service of Intermountain
reflect a just, fair, and equitable pass-through of changes in gas related costs to Intermountain's
customers.
XVII.
This Application has been brought to the attention of Intermountain's customers through a
Customer Notice and by a Press Release sent to daily and weekly newspapers, and major radio and
television stations in Intermountain's service area. The Press Release and Customer Notice are
attached and incorporated by reference. Copies of this Application, its Exhibits, and Workpapers
have been provided to those parties regularly intervening in Intermountain's rate proceedings.
xwI
Intermountain requests that this matter be handled under modified procedure pursuant to
Rules 201-204 of the Commission's Rules of Procedure. Intermountain stands ready for immediate
consideration of this matter.

Dear Mr. Charlebois:
Foothills Pipe Lines Ltd. (Foothills)
Statement of Rates and Charges effective January lr202l
Foothills encloses for filing pursuant to section 229(l)(a) of the Canadian Energt Regulator Act
rates and charges for transportation service on Foothills Zones 6,7, 8 and 9 to be effective
January 1, 2021 (Effective 2021 Rates).
The following attachments are included with this letter:
r Attachment I consists of supporting Schedules A through Gt
a Attachments 2 aad3 are blackJined and clean copies, respectively, of the Table of
Effective Rates for 2021
The rates and charges are based on the methodology approved in Order TG-8-2004, as amended
by Order TG-03-2007.
The filing also includes the Foothills Abandonment Surcharges effective January l, 2021, which
are included in the Table of Effective Rates for 202l.The supporting information on the
Abandonment Surcharge calculations are provided in the attached Schedule G.
Foothills met with shippers and interested parties on October 23,2020 and presented the
preliminary 2021 revenue requirement, preliminary Effective 2021 Rates and preliminary
Abandonment Surcharges. Based on this consultation, Foothills is not aware of any objections to
its proposal for establishing the Effective 2021 Rates.
Foothills understands that any party that is opposed to the rates and charges will advise the
Commission accordingly.
I Schedule C from previous years' filings has been terminated as the related Special Charge has been fully
amortized and is no longer applicable. As a result, the previous Schedule C-l has been relabeled to Schedule C in
the current filing. In addition, Schedule C will only show depreciation by account by zone annually rather than
monthly.
