ORDER NO. 35279

On September 24, 2021, Intermountain Gas Company (“Company”) submitted Tariff
Advice No. 21-01 requesting to revise Section C of its General Service Provisions in its tariff. The
Company specifically sought authority to update the Allowable Investment Factors (“AIF”), the
Service Line Cost per Foot (“SLCF”), and the construction overhead charge, all in accordance with
Commission Order No. 34735. Application at 1. The Company also sought to revise language in
the tariff to provide additional clarity. Id. at 2. The Company requested that the proposed changes
become effective December 1, 2021.
At the October 12, 2021, Decision Meeting, Commission Staff stated they need
additional time to review the Company’s filing and recommended that the Tariff Advice be
processed as a formal case to allow for greater transparency and public input. See October 8, 2021,
Decision Memorandum at 1. Staff further recommended to suspend the Company’s December 1,
2021, proposed effective date and process the case under Modified Procedure. Id. Staff indicated
the Company concurred with the above-mentioned approach, but that the Company requested an
additional 30 days after the Commission’s final decision on its proposed revisions to implement
the changes to its systems and forms. Id. at 2.
On October 18, 2021, the Commission converted the Tariff Advice into an Application,
issued a Notice of Application, a Notice of Modified Procedure setting public comment and
Company reply deadlines, and suspended the Company’s proposed effective date.
Having reviewed the record, the Commission issues this Order approving the
Application.
BACKGROUND
The Company is authorized by the Commission to “file an annual tariff advice to
update the [AIF], the [SLCF], and the construction overhead charge.” Order No. 34735 at 9.

ORDER NO. 35279 2

THE APPLICATION
The Company proposed to update the AIF, the SLCPF, and the construction overhead
charge in Section C of its General Service Provisions. The Company also proposed to revise the
language in section 4.2(a) of its tariff “to remove the ambiguous reference to ‘Non-discretionary
load’ and replace it with the word ‘Gas.’” Application at 2. The Company also proposed a tariff
revision to “remove the reference to ‘stubs’ in section 5.3 because stubs are not included in the
main project cost estimate.” Id. Rather, as the Company stated, “[s]tub costs are included in the
average service line cost per foot referenced in section 5.2.” Id. The Company attached sheets to
its Application that explicated the proposed changes and revisions.
STAFF’S COMMENTS
Staff reviewed the Company’s Application and concluded that the methods used to
update the AIF, the SLCPF, and the construction overhead charge in its tariff were reasonable and
consistent with the methods approved in Commission Order No. 34735. Staff believed the
proposed revisions to the language in the Company’s tariff were reasonable and should be
approved. Staff Comments at 2.
COMMISSION FINDINGS AND DISCUSSION
The Company is a gas corporation and public utility, and the Commission has
jurisdiction over it and the issues in this case under Title 61 of the Idaho Code. The Company is
a Commission-regulated public utility under Idaho Code § 61-129 and a gas corporation under
Idaho Code § 61-117. Based on our review of the record, we find that the Company’s proposed
changes to its tariff are reasonable and consistent with our prior orders. We thus find it fair, just,
and reasonable to approve the Company’s proposed updates and language revisions to its tariff.
O R D E R
IT IS HEREBY ORDERED that the Company’s Application for authority to update
and revise language in its tariff is approved.
IT IS FURTHER ORDERED that the Company shall implement the changes and
revisions to its systems and forms within thirty (30) days of the service date of this Order.
THIS IS A FINAL ORDER. Any person interested in this Order may petition for
reconsideration within twenty-one (21) days of the service date of this Order regarding any matter
decided in this Order. Within seven (7) days after any person has petitioned for reconsideration,
any other person may cross-petition for reconsideration. See Idaho Code § 61-626.
