(e) Please refer to the Company's response to subpart (e) below:
• Ref#79 "RMP 2023 UT Fire Mitigation Vehicles"was booked to FERC
Plant Account 1064000 General Completed Construction Not Classified
and is allocated using the system overhead(SO) allocation factor.
When projects are closed and placed in-service, project costs are often
tentatively capitalized to, or recorded under, FERC Account 106
(Completed construction not classified-electric) assuming a functional
category based on the broad functional category of work that the project
pertains and without a state-specific location code. Allocation factors are
assigned based on a combination of the FERC Plant account and location
code. Since there is no state-specific location code associated with the
FERC Account 106 accounting entry, a default SO allocation factor is
assigned to the plant function general plant. Over time, the Company
performs a more detailed analysis of amounts placed in-service to transfer
balances out of FERC Account 106 and into the appropriate electric plant
accounts within FERC Account 101, with a specific location code. When
the FERC Account and location code are recorded, the proper allocation is
assigned. At the time this general rate case (GRC) filing was made, the
analysis for final plant account and location determination had not been
performed on all in-service plant balances.
• Ref#211 "RMP 2022 UT Fire Mitigation Vehicles"—The 2022 amount of
$11,978 was booked to FERC Plant Account 3921400 Snowmobiles-
