Intermountain Gas Company ("Intermountain" or "Company") respectfully submits the
following Reply Comments in response to Comments filed by the Idaho Public Utilities
Commission Staff("Staff') the city of Boise City ("Boise City"), and the Idaho Conservation
League ("lCL"), as well as limited Reply Comments to public comments filed by the Rocky
Mountain Propane Association ("RMPA"), Chad Worth and Craig Smith.

lntermountain filed an application on January 27,2020 requesting authority to revise the
Company's General Service Provisions related to the installation and extension of natural gas
mains and services ("Line Extension Policy''). On February 25,2020, the Commission issued
Order No. 34560 setting a March ll , 2020 intervention deadline and suspending the Company's
proposed April 1, 2020 effective date for the tariff for 30 days plus 5 months, or until October l,
2020.
INTERMoT.INTAIN GAs Coupelw's Rgplv CouupNts - I
The primary purpose of a Line Extension Policy as outlined in Staff comments, "is to
assure equity between new and existing customers. A Line Extension Policy should assure that
the costs of new interconnections are not unfairly shifted to existing customers, while also
assuring that the new customers do not pay more for their interconnection than is necessary."
Staff Comments at 2.
Rrply To Sr.lrr Courvrpxrs
Intermountain appreciates Staf|s Comments and the thorough review and input on the
Company's proposed methodology in this case.
As Staff mentions, the Company has offered to make refunds for projects completed
between the conclusion of the last rate case (INT-G-I6-02) and the implementation of this tariff.
StaffComments at 8. Intermountain recognizes there are good arguments for and against issuing
refunds and does not take a firm position on either side. However, Intermountain does not
believe there is any justification for requiring the Company to book a refund below the line as a
penalty in this situation. Intermountain was following the approved Line Extension Policy at the
time these projects were completed, and as illustrated throughout StafPs Comments, the
Company has made a good faith effort to work through this complex revision with Staffin a
timely maruler. As such, Intermountain requests that the Commission either allow refunds
without booking them as a penalty, or that the Commission disallow refunds.
Staff recommends an effective date of August 1,2020. lntermountain respectfully
requests that the effective date remain at the suspended effective date of October 1,2020 that
was established in Order No. 34560. Intermountain's traditional construction season runs from
spring through fall. While it is impossible to set a date that provides a completely seamless
transition between the two tariffs, a date at the end of the construction season will result in less
confusion for customers than a date in the middle of the construction season. An effective date of
INtenuouNrnrN Ges CoMpAl.ry's Rrpr.y CorrluBNrs - 2
October 1,2020 will allow the Company to adequately communicate impending changes with
developers, builders, and customers prior to the start of the 2021 construction season. In addition,
the Company has been referencing the October 1,2020 suspended effective date when discussing
projects with customers to make sure those customers are informed that there will be a difference
in the project costs if they wait to begin a project until after the new tariffis effective. The
Company has also faced unexpected challenges in system development and training on the
proposed tariff due to the challenges brought about by COVID-19. For these reasons,
lntermountain believes that the October I,2020 effective date will avoid unnecessary confusion
and requests an effective date of October 1,2020 rather than August 1,2020.

Intermountain agrees with Boise City regarding the important role natural gas plays in
affordable housing, economic development, and the viability of reaching clean and renewable
energy goals through the use of renewable natural gas.
Boise City raises several questions throughout their comments. Intermountain would
welcome the opportunity to discuss these points with Boise City in an informal setting. In this
Reply, lntermountain will point Boise City to sources of information within the case that may
address the questions.
Boise City raises a question regarding the decrease in the allowable investment. As the
Company's Application outlines beginning on Page 8, the proposed tariff will have varying
impacts on the need for and amount of upfront payments from individual customers depending
on whether the proposed project requires a service line only or if it is a combined main and
service line extension.
Additional information is also requested for the consffuction overhead percentage. As
Staffindicates in their Comments, the Company provided a detailed description and work papers
INrgnuouurerN Ges CotvtpAxv's Replv CotvttvtrNrs - 3
that outline the calculation of the construction overhead percentage in its response to Production
Request Nos. l-3. StaffComments at 8. lntermountain has provided these materials to the City
and would welcome the opportunity to discuss directly with the City.
Boise City also requests an explanation of why the Exhibit No. 3 Musgrove Engineering
study (Musgrove) includes the use of 80% efficient fumaces instead of 95o/o efficient fumaces.
As outlined on Exhibit No. 3, Page 2, Section 2, the study modeled both an 80o/o efficient and a
95o/o efftcient furnace. The table "Load Factor Averaging Assumptions Per Climate Zone" on
Page 6 of Exhibit No. 3 reports the weighting used between the two different furnace types.
Although the Department of Energy submitted a proposal to raise the minimum effrciency level
for fumaces from 80%, that rulemaking has received some challenges and is still making its way
through the rulemaking process. There is not yet clear direction on whether the minimum
efficiency level will be increased, and, if it is increased, to what level. Therefore, 80o/o fumaces
are still being installed routinely in new construction and are thus appropriately included in
Exhibit No. 3.
Rprr,v ro ICL CounnrNrs
Intermountain appreciates the opportunity to address ICL's concerns that the proposed
Line Extension Policy uses assumptions that may overstate methane consumption. The Company
believes ICL's concerns are based on misinterpretations of the Musgrove study. The Musgrove
study is based on the current new construction environment across the Company's service
territory. As Staffindicates in their Comments, the Musgrove study was calibrated and validated
using actual consumption data from homes constructed during the 2015 and 2016 calendar years.
StaffComments at 5. Thus, the Musgrove study does not assume that customers will build
homes to meet minimum code levels or install minimally efficient appliances as ICL asserts.
Rather, it assumes that some customers will build to code, but that others will go beyond code
INtenvomlrerN GeS CoupeNy's Rrply CorrluENTs - 4
and install energy efficiency upgrades as the actual building mix demonstrates.
ICL also states that the modeling assumes a full suite of gas appliances in the homes
modeled. While the Musgrove study does include an analysis of non-heating as well as heating
load, as noted on Exhibit No. 3, Page 6, "The non-heating appliance gas usage was separated
from the overall building heating consumption." This allowed for the development of the heating
consumption factor of 0.234 (Exhibit No. 3, Page 6) as well as the non-heating appliance annual
gas consumption found on Exhibit No. 3, Page 1 l. The modeling that resulted in the heating
consumption factor, therefore, does not assume customers will install a full suite of gas
appliances. Staffreviewed both calculations and found them to be reasonable. Staff Comments at
5 and 6.
Additionally, ICL expresses concem that the Company proposes the use of an average
allowable investment across its system. While the Musgrove study did find differences in
temperature, code, and building practices across the Company's service territory, these
differences were offsetting and thus produced results that were similar regardless of location. As
noted in StaffComments, "Although winter temperatures are generally cooler inZone 68 than
they are inZone 58, more stringent Zone 6B IECC building standards result in consumption that
is similar in both zones." Staff at 5. While Intermountain agrees that precision is important, when
simple calculations result in a similar answer to extrernely complex calculations, the simpler
calculations generally result in a tariffthat is easier to explain and understand. For this reason,
lntermountain chose to use the simple, but accurate, allowable investrnent factor proposed in its
application. Application at 5.
Finally, ICL argues that the line extension policy should encourage efficiency through a
tiered cost methodology. Intermountain believes that its Energy Effrciency program is a better
INTERMoUNTATN Ges CoMPANY'S REpI-v CouruBNrs - 5
mechanism to encourage customers to consider efficiency improvements than a complicated,
punitive line extension policy.
Rnplv ro CoMMENTS REGARDTNG Eeurry
The Comments submitted by Boise City, ICL, RMPA, Chad Worth and Craig Smith all
note the importance of equity in setting line extension policy. Boise City expresses concern that
the proposed tariff may increase the costs of residential and commercial construction projects.
Boise City at 2. Craig Smith states that the proposed tariffwill "create an undue hardship on
developers/builders and in return future homeowners." Craig Smith at l. Both Boise City and
Craig Smith are concerned that the increase in costs from this proposal will impact housing
prices and affordability.
On the other hand, ICL, RMPA, and Chad Worth raise concerns about the possibility of
existing customers subsidizing line extensions to new customers by not imposing enough costs
on new construction. RMPA encourages the Commission to "closely scrutinize any proposals
which would result in the subsidized extension of their gas delivery system to new applicants."
RMPA Comments at2. ICL recommends that, "the Commission direct Intermountain to develop
a line extension policy that directly assigns all of the costs to the entity requesting new service."
ICL Comments at 2.
These comments illustrate the difficulty in balancing the dual objectives of ensuring that
both existing and new customers are treated fairly. Because part of any customer's monthly
charges are designed to recover a portion of the distribution system required to serve them, it
would be unfair to require new customers to pay the entire cost of a project up front and then pay
for their distribution system again through their base rates. However, not charging a new
customer enough up front will result in upward pressure on rates and existing customers
subsidizing the costs of system expansion. As StaffComments discuss, the embedded cost
INrpnuouNrerN Ges Coupelw's Rnply CorraurNrs - 6
methodology proposed by the Company appropriately balances the equities between new and
existing customers. StaffComments at 2.
Coxcr,usrox
In summary, lntermountain believes its proposed Line Extension Policy strikes an
appropriate balance of ensuring equity between new and existing customers, results in a tariff
that is simpler and easier for customers to understand and includes important update provisions
that will keep the tariffcurrent. Intermountain respectfully requests the Commission:
a) approve Intermountain's Line Extension Policy as filed,
b) determine whether or not customer refunds are appropriate and if appropriate instruct
Intermountain to make those refunds above the line,
c) establish an October 1,2020 effective date for the tariff.
