Ms. Jan Noriyuki Commission Secretary Idaho Public Utilities Commission P.O. Box 83720 Boise, ID 83720-0074
RE: Intermountain Gas Company Tariff Advice No. 23-02
Dear Ms. Noriyuki: Enclosed for filing with this Commission is a copy of Intermountain Gas Company’s proposed revision to its General Service Provisions, Section C, Sheet 3.
Section C, 3.2 currently states the Company will charge an applicant for relocation or abandonment of Company-owned, gas facilities when the action is requested by the applicant. This filing removes abandonment of gas facilities as an action requiring a charge since the removal or safe guarding of abandoned facilities is done in a timely manner to protect the public’s
safety rather than an action that is done at the applicant’s convenience. The Company requests that the proposed revisions become effective June 5, 2023. If you have any questions or require additional information regarding the attached, please contact me at [phone].
Sincerely, /s/ Lori A. Blattner
Lori A. Blattner Director – Regulatory Affairs Intermountain Gas Company

applicant when required by the applicant.
3.3 The applicant may be required to reimburse the Company for the installation, extension, or
abandonment of Gas Facilities if the terms of the signed agreement are not met.

3.5 The Company will install a single Service per applicant, unless the applicant requests an
additional Service. The Company may provide an additional Service on a case-by-case basis,
provided there is over one-hundred-feet between meter locations. Each Service must follow the
provisions of this section. The Company may waive the one-hundred-foot requirement when an
additional Service is required for Multifamily or Interruptible Snowmelt Service (Rate Schedules
IS-R and IS-C).
4.ALLOWABLE INVESTMENT
4.1 The Allowable Investment for Services and Mains is determined by first calculating the estimated
annual therm usage and then applying the Allowable Investment Factor per therm.
4.2 The estimated annual therm usage is calculated as follows:
(a)For residential applicants:
When natural gas is the primary heat source, calculate the estimated annual space heating
therm usage by multiplying the square foot factor of 0.234 by the square footage of the home.
To the estimated annual space heating therm usage, add gas appliance annual therm usage
estimates from the chart below, as applicable, to calculate the total estimated therm usage
per year. Gas appliances not on this list can be estimated by the Company on a case-by-
case basis. In residential Developments where specific appliances are unknown at the time
of calculation, the Company will base therm estimates on only the estimated annual space
heating therm usage plus the water heater therm estimate.
