CUSTOMER NOTICE
13. Gem State certifies that it is notifying customers of the Application by inserting a
notice on each customer's bill starting on December 27, 2024 or as soon as possible thereafter. A
press release will be mailed or delivered to the Coeur d'Alene Press on December 27, 2024.
Copies of the notice and press release are included as Exhibit No. 7.
TEST YEAR AND RATE BASE
14. Gem State proposes the 12 months ended September 30, 2024 as the test year in
this case, with adjustments to normalize and pro forma the test year for known and measurable
changes.
15. Exhibit No. 1,presents the Company's calculation of rate base. Column (A) of
this exhibit represents the balances of accounts on the books of the Company as of September
1 The Company is proposing to bill all customers in gallons as now measured by all meters across the Gem State
Water platform,so converting usage measured in cubic feet no longer is needed.
APPLICATION PAGE 6 OF 12

30, 2024.Pro forma adjustments consisting of plant additions expected to be in service by
January 30, 2025 are summarized in Column(B). Column(C) shows the calculation of
Applicant's pro forma rate base of$3,802,710.
16. The pro forma adjustments summarized in Column(B) are detailed in Exhibit 1
(D). The Bitterroot system rebuild is the biggest single project listed there and accounts for over
half of the dollar value of the pro forma plant additions. The meter replacement program is
another large part of the pro forma plant additions.
RESULTS OF OPERATIONS
17. Exhibit No. 2 presents the Company's Results of Operations (Income Statement)
adjusted for known and measurable changes. Column(A) of the exhibit presents the actual
recorded results of the Company for the 12 months ended September 30, 2024. The reported
income tax is a calculated number with the calculation shown on Exhibit 2(B). These results are
adjusted in Columns (B) through(D)to develop the adjusted results shown in Column (E) that
are used to establish the Company's revenue requirement.
18. Column(B) shows increases in labor costs resulting from employee raises and the
hiring of a new part time employee. These labor cost increases are detailed in Exhibit 2 (A). The
incremental labor costs are required to operate and maintain the respective systems and respond
to customers. The total payroll costs are allocated among Gem State Water; Gem State
Infrastructure, LLC (a non-Commission regulated affiliate) ("Infrastructure"); and the Pelican
Point Water system in Moses Lake, Washington, owned by Cascadia Water, LLC and operated
by Infrastructure (regulated by the Washington Utilities and Transportation Commission) on a
direct allocation and customer count basis.
19. Column(B) also includes rate case expense which is detailed on Exhibit 2(C).
APPLICATION PAGE 7 OF 12

20. Column(C) shows the increase in depreciation expense associated with the pro
forma plant additions summarized in Column(B) of Exhibit 1.
21. Column(D) shows the calculated change in income tax as a result of the other pro
forma additions.
22. Column(E) shows the total pro forma income statement. On a pro forma basis,
the Company's operating income is negative $46,342.
COST OF CAPITAL
23. Exhibit No. 3 presents the Company's capital structure and the weighted cost of
capital as of September 30, 2024. The requested return on equity is 10.2%. Gem State is
proposing a hypothetical capital structure of 55% equity/45% debt consistent with the capital
structure approved in Order No. 35692. Gem State is proposing a 5.22% cost of debt which is the
actual cost of debt of NW Natural Water, the holding company that owns NW Natural Water of
Idaho, the direct owner of Gem State. These values produce an overall weighted cost of capital
for Gem State Water of 7.96%.
REVENUE REQUIREMENT
24. Exhibit No. 4 presents the revenue requirement for Gem State.
25. Lines 1 through 5 of Exhibit 4 develop the net operating deficiency of$349,000
shown on line 5 utilizing the rate base, rate of return and operating results from Exhibits Nos. 1,
2, and 3. Lines 6 through 8 calculate the revenue increase necessary to overcome the income
deficiency. The incremental revenue requirement is $494,808, which represents an increase in
the Company's revenues of 64.8%.
APPLICATION PAGE 8 OF 12

RATE DESIGN
26. Exhibit No. 5 presents the Company's current and proposed rates. The Company
is proposing full consolidation of rates across the six current tariffs.2 The proposed rates collect
54% of the revenue requirement from the Monthly Minimum Charges and 46% from the
Commodity charge per 1,000 gallons.
27. Each of the current tariffs include an allowance of free gallons in the monthly
minimum. Such an allowance is contrary to the goal of encouraging conservation and we are
unclear on its basis in cost of service. However, we are not proposing to eliminate the free
allowances entirely in this rate case. The Company is proposing to reduce the allowances for
each meter size. The Company's long-term goal is to eliminate the free allowances entirely but
will do so gradually.
28. There are several benefits to the consolidation of rates: enhanced customer service
and ease of doing business, reduced customer confusion, and mitigated rate impacts related to
large capital investments.
29. The consolidation of rates allows for improved customer service and
responsiveness by reducing the complexity of the tariff structure. Reducing the number of tariffs
and rates improves understanding of tariffs and rates for both customers and staff, which in turn
should further enhance the customer experience.
30. The larger customer base also mitigates rate volatility for the different systems.
Water utilities are highly capital intensive, and a relatively large investment can significantly
impact rate base and the associated revenue requirement. Additionally, facilities, technology and
2 In the Company's last rate case,the Commission approved partial consolidation,explaining that doing so"offers
administrative efficiency and is a necessary step towards attaining uniform rates and charges for all customer classes
on the eight Commission-regulated systems owned and operated by Gem State." Case No.GSW-W-22-01,Order
No. 35692(dated March 1,2023),p. 16.
APPLICATION PAGE 9 OF 12

other shared investments impact all customers, rather than a single system. As the Commission
explained in Gem State Water's last rate case, "in the long term, consolidating systems by
implementing uniform rates and charges will help spread the costs of system-wide improvements
among a larger body of customers more equitable,"which"will ultimately benefit all Gem State
customers now and in the future."3
31. Exhibit 6 shows the bill impacts of the Company's proposed rates for the typical
customers on each current tariff and meter size. The vast majority of customers are on 1"meters.
The median 1"usage across all the current tariffs is used to represent the typical customer.
Currently the median usage is less than the free usage allowance included with the minimum
charges on all of the current 1 inch tariffs. The proposed lower free usage allowance results in
the median customer's bill including commodity charges under the proposed rates. Under
proposed rates, the median use customer will experience an increase between $18.67 and $24.67
depending on their current tariff. The bill impacts across the six systems are thus fairly similar
with no systems experiencing bill impacts disproportionate to what other systems would
experience. The proposed consolidation affects customers across the six systems in a fairly
similar manner and thus does not present equity issues.
32. The 1.5-inch and 2-inch minimum charges both intend to align costs with the rates
charged to customers, as larger services require more system capacity. The Company has no
customers on meters larger than 2 inches but is proposing rates for 3, 4, and 6-inch meters in its
tariff to prepare for the eventuality of a larger customer requesting service.
I Case No. GSW-W-22-01,Order No.35692(dated March 1,2023),p. 16. Similarly,the Commission more
recently stated in the last rate case of Gem State Water's affiliate,Falls Water,that it"support[s]the move towards
increased consolidation of rates for the Falls Water,Morning View,and Taylor Mountain water systems"and
"encourage[s]the Company to continue working towards consolidation of the three water systems"so that
"customers are treated more equitably in rates and that customers are receiving appropriate price signals." Case
FLS-W-23-01,Order No.36027(dated December 14,2023).
APPLICATION PAGE 10 OF 12

33. The Company is proposing to charge its customers with irrigation meters the same
rates as other meters. The current irrigation rates are very similar to the other tariffed rates so this
is not a dramatic change. The Company has provided a service to irrigation customers whereby it
removes and stores their meters through the winter and then reinstalls them each spring. The
Company is proposing to introduce a charge of$50 per year for that service.
REQUEST FOR RELIEF
34. Gem State stands ready for immediate consideration of this Application.
35. Gem State respectfully requests that the Commission issue an Order:
i. Approving use of modified procedure to process this Application;
ii. Finding that the changes to rates, charges, and conditions of service proposed
in this Application are just and reasonable;
iii. Approving the changes to Applicant's rates, charges, conditions of service as
proposed in this Application, effective on or after February 1, 2025;
iv. Approving tariffs that reflect the changes to Applicant's rates, charges, and
conditions of service as proposed in this Application;
V. Granting other relief as the Commission determines proper under the
circumstances.

the Company's tariff and approved by the Commission.
6. BILLING AND PAYMENT
6.1 All Customers shall be billed on a regular basis as identified on the
applicable rate schedule.
6.2 If the system is metered, the Company shall try to read the meters
prior to each billing unless specified differently on the applicable rate
schedule. If the Company's meter reader is unable to gain access to
the premises to read the meter, or in the event the meter fails to
register, the Company will estimate the Customer's water consumption
for the current billing period based on known consumption for a prior
similar period or average of several periods. Subsequent readings will
automatically adjust for differences between estimated and actual.
Bills based on estimated consumption shall be clearly marked as
"estimated".
6.3 All bills shall clearly indicate the balance due, and may be due and
payable no less than 15 days after the date rendered. All bills not paid
by due date may be considered delinquent and service may be
disconnected subject to the provisions of the UCRR.
6.4 A Late Payment Charge may be levied against any delinquent account.
All payments received by the next billing date shall be applied to the
Customer's account prior to calculating the Late Payment Charge.
6.5 The minimum bill or customer charge shall apply when service is
provided for less than one month.
6.6 Owners of premises with one or more condominiums, buildings, stores,
apartments or any other divisions of like or similar character, all of
which are served from one (1) service connection are responsible for
the entire water charges. If the owner desires to cease being
responsible for water bills for such places and desires that the
occupant of each division will be responsible for her or her respective
bill, such transfer of responsibility will not be accepted or recognized
by the Company until the plumbing arrangements of the building or
premises are so changed by the owner or his or her agent as to permit

readings. In the event of recurring inaccessibility the Company may,
at its option and after notifying the customer, relocate its metering
equipment at the Customer's expense.
7.3 The Company shall be responsible for the maintenance of its metering
equipment. Meters are considered to be sufficiently accurate if tests
indicate that meter accuracy is within + 2 percent. When for any
reason a meter fails to register within these limits of accuracy, the
Customer's use of water shall be estimated on the basis of available
data and charges shall be adjusted accordingly. Corrected bills shall
then be sent out to the customer and additional payment or refund
arrangements shall be made in accordance with the UCRR.
7.4 The Company reserves the right to test and/or replace any meter.
Upon deposit of a "Meter Testing Fee" by a Customer, the Company
will test the Customer's meter. If the test indicates that the meter
over-registers by more than 2 percent, it shall be replaced with an
accurate meter at no cost to the Customer and the "Meter Testing Fee"
shall be refunded and water bills shall be adjusted in accordance with
the UCRR. Meter Testing Fees shall require prior approval by the
Commission.
7.5 At the Company's discretion, un-metered Customers may be converted
to metered service if such transition occurs in a planned, systematic
manner without unreasonable discriminations and if the Company has
an approved metered rate.
7.6 The Company will have the right to set meters or other devices
without notice to the Customer for the detection and prevention of
fraud.

premises.
8.2 The plumbing, piping, fixtures and appliances shall be maintained in
conformity with all municipal, state and federal requirements. The
nature and condition of this plumbing, piping and equipment will be
such as not to endanger life or property, interfere with service to other
Customers or permit those with metered services to divert system
water without meter registration.
8.3 A stop-and-waste valve will be installed on the Customer's plumbing in
a place always accessible and so located as to permit shutting off the
water for the entire premises with the least possible delay.
8.4 All persons having boilers, water tanks or other equipment supplied by
direct pressure from the Company's mains should install a pressure
relief valve, or other device to serve the same purpose, so as to
prevent excess pressure from forcing hot water and/or steam back
into the water meter and mains of the Company. All damage to the
Company's property resulting from the failure to properly equip
plumbing with a relief valve will be billed to the Customer.
8.5 The Company is not obligated to perform any service whatever in
locating leaks or other trouble with the customer's piping.
8.6 When the premises served by the Company are also served in any
manner from another water supply of any kind, an approved backflow
prevention device shall be installed at the service connection. Water
service for either stand-by or other purposes will not be furnished until
piping and connections are inspected and approved by a
representative of the Company.

cost of said service connection. If within a period of five (5) years
from the installation of said service connection a permanent structure
is erected on the premises, the Company will refund, with interest, the
difference between any approved new Customer charges in effect at
the time of connection, and the applicant's advance.

additional equipment or special construction techniques involved in the
installation of a service connection will be agreed to in advance by the

disconnected, either voluntarily or involuntarily, and reconnected at
the same premises. The reconnection fee will be paid before service is
restored. Reconnection fees shall not be charged for any situation or
circumstance in which the Customer's water supply is disconnected by
the Company for its convenience.

UNIFORM MAIN EXTENSION RULE FOR WATER UTILITIES
Based on Order No. 7830 (Case No. U-1500-22)
A. GENERAL PROVISIONS AND DEFINITIONS
1. Applicability
a. All extensions of distribution mains from the utility's existing distribution system,
to serve new customers, except for those specifically excluded below shall be
made under the provisions of this Rule unless specific authority is first obtained
from the Commission to deviate therefrom. A main extension contract shall be
executed by the utility and the applicant or applicants for the main extension
before the utility commences construction work on said extension or, if
constructed by applicant or applicants, before the facilities comprising the main
extension are transferred to the utility.
b. Extensions solely for fire hydrant, private fire protection, resale, temporary,
standby, or supplemental service shall not be made under this Rule.
c. The utility may, but will not be required to, make extensions under this Rule in
easements or rights-of-way where final grades have not been established, or
where street grades have not been brought to those established by public
authority. If extensions are made when grades have not been established and
there is a reasonable probability that the existing grade will be changed, the
utility shall require that the applicant or applicants for the main extension
deposit, at the time of execution of the main extension agreement, the estimated
net cost of relocating, raising, or lowering facilities upon establishment of final
grades. Adjustment of any difference between the amount so deposited and the
actual cost of relocating, raising, lowering facilities shall be made within ten (10)
days after the utility has ascertained such actual cost. The net deposit
representing actual cost is not subject to refund. The entire deposit related to the
proposed relocation, raising or lowering shall be refunded when such
displacements are determined by proper authority to be not required.
2. Definitions
a. Bona- Fide Customer, for the purposes of this Rule, shall be a customer
(excluding any customer formerly served at the same location) who has given
satisfactory evidence that service will be reasonably permanent to the property
which has been improved with a building of permanent nature and to which
service has commenced. The provision of service to a real estate developer or
builder during the construction or development period shall not establish him as a
bona fide customer.
b. Real Estate Developer or Builder, for purposes of this Rule, shall include any
individual, association of individuals, partnership, or corporation that divides a
parcel of land into two (2) or more portions.

c. Adjusted Construction Cost, for the purposes of this Rule, shall be reasonable and
shall not exceed the costs recorded in conformity with generally accepted water
utility accounting and sound engineering practices, and as specifically defined in
the, Uniform System of Accounts for Water Utilities prescribed by the
Commission, of installing facilities, of adequate capacity for the service
requested. If the utility at its option should install facilities with' a larger capacity
or resulting in a greater footage of extension than required for the service, the
adjusted construction cost for the purposes of this Rule shall be determined by
the application of an adjustment factor to actual construction cost of facilities
installed. This factor shall be the ratio of estimated cost of required facilities to
estimated cost of actual facilities installed.
d. Commission shall mean the Idaho Public Utilities Commission.
3. Ownership, Design and Construction of Facilities
a. Any facilities installed hereunder shall be the sole property of the utility. In those
instances in which title to certain portions of the installation, such as fire
hydrants, will be held by a political subdivision, such facilities shall not be
included as a part of the main extension under this Rule.
b. The size, type, quality of materials and their location shall be specified by the
utility and the actual construction shall be done by the utility or by a constructing
agency acceptable to it.
c. Where the property of an applicant is located adjacent to a right-of-way,
exceeding 70 feet in width, for a street, highway or other public purpose,
regardless of the width of the traveled way or pavement; or a freeway, waterway
or railroad right-of-way, the utility may elect to install a main extension on the
same side thereof as the property of the applicant and the estimated and
adjusted construction costs in such case shall be based upon such an extension.
d. When an extension must comply with an ordinance, regulation, or specification of
public authority, the estimated and adjusted construction costs of said extension
shall be based upon the facilities required comply therewith.
4. Estimates, Plans and Specifications
a. Upon request by a potential applicant for a main extension, the utility shall
prepare without charge a preliminary sketch and rough estimates of the cost of
installation to be advanced by said applicant.
b. Any applicant for a main extension requesting the utility to prepare detailed
plans, specifications and cost estimates shall be required to deposit with the
utility an amount equal to the estimated cost of preparation of such material. The
utility shall, upon request, make available within 45 days after receipt of the
deposit referred to above, such plans, specifications and cost estimates of the
proposed main extension. If the extension is to include oversizing of facilities to
be done at the utility's expense appropriate details shall be set forth in the plans,
specifications and cost estimates.

c. In the event a main extension contract with the utility is executed within 180'
days after the utility furnishes the detailed plans and specifications, the deposit
shall become a part of the advance, and shall be refunded in accordance with the
terms of the main extension contract. If such contract is not so executed the
deposit to cover the cost of preparing plans, specifications and cost estimates
shall be forfeited by the applicant for the main extension and the amount of the
forfeited deposit shall be credited to the account or accounts to which the
expense of preparing said material was charged.
d. When detailed plans, specifications and cost estimates are requested the
applicant for a main extension shall furnish a map to a suitable scale showing the
street and lot layouts, and when requested by the utility, contours or other
indication of the relative elevation of the various parts of the area to be
developed. If changes are made subsequent to the presentation of this map by
the applicant, and these changes require additional expense in revising plans,
specifications and cost estimates this additional expense shall be borne by the
applicant, not subject to refund, and the additional expense thus recovered shall
be credited to the account or accounts to which the additional expense was
charged.
5. Timing and Adjustment of Advances
a. Unless the applicant for the main extension elects to arrange for the installation
of the extension himself as permitted by Section C.1.c., the full amount of the
required advance or an acceptable surety bond must be provided to the utility at
the time of execution of the main extension agreement.
b. If the applicant for a main extension posts a surety bond in lieu of cash, such
surety bond must be replaced with cash not less than ten (10) calendar days
before construction is to commence; provided, however, that if special facilities
are required primarily for the service requested, the applicant for the extension
may be required to deposit sufficient cash to cover the cost of such special
facilities before they are ordered by the utility.
c. An applicant for a main extension who advances funds shall be provided with a,
statement of actual construction cost and adjusted construction cost showing in
reasonable detail the cost incurred for material, labor, any other direct and
indirect costs-, overheads, and total costs; or unit costs or contract costs;
whichever are appropriate.
d. Said statement shall be submitted within sixty (60) days after the actual
construction costs of the installation have been ascertained by the utility. In the
event that the actual construction costs for the entire installation shall not have
been determined within 120 days after completion of construction work, a
preliminary determination of actual and adjusted construction costs shall be
submitted, based upon the best available information at that time.
e. Any differences between the adjusted construction costs and the amount
advanced shall be shown as a revision of the amount of advance and shall be
payable within thirty (30) days of submission of the statement.

only to those refunds which become due more than thirty (30) days after the date of
receipt by the utility of the notice of assignment. The utility shall not be required to
make any one refund payment under such contract to more than a single assignee.
7. Interpretations and Deviations - In case of disagreement or dispute regarding the

the estimated reasonable cost of such extension which exceeds the estimated
reasonable cost of 50 feet of the main extension per service connection, exclusive of
the cost of service pipes, meter boxes and meters. Such estimated reasonable cost
shall be based upon the cost of a main not in excess of six (6) inches in diameter

reasonable manner at the same location. At the request of the applicant, refunds
shall be made within 180 days after the date of first service to a bona fide customer.
If no request is received from applicant the utility shall, initiate refunds on an annual
basis. No refunds shall be made, after a period of ten (10) years from the date of

occupant of each division will be responsible for her or her respective
bill, such transfer of responsibility will not be accepted or recognized

premises are so changed by the owner or his or her agent as to permit
the Company, to its satisfaction, to serve each division or occupant

a place always accessible and so located as to permit shutting off the
water for the entire premises with the least possible delay.

direct pressure from the Company's mains should install a pressure
relief valve, or other device to serve the same purpose, so as to

UNIFORM MAIN EXTENSION RULE FOR WATER UTILITIES
Based on Order No. 7830 (Case No. U-1500-22)
A. GENERAL PROVISIONS AND DEFINITIONS
1. Applicability
a. All extensions of distribution mains from the utility's existing distribution system,
to serve new customers, except for those specifically excluded below shall be
made under the provisions of this Rule unless specific authority is first obtained
from the Commission to deviate therefrom. A main extension contract shall be
executed by the utility and the applicant or applicants for the main extension
before the utility commences construction work on said extension or, if
constructed by applicant or applicants, before the facilities comprising the main
extension are transferred to the utility.
b. Extensions solely for fire hydrant, private fire protection, resale, temporary,
standby, or supplemental service shall not be made under this Rule.
c. The utility may, but will not be required to, make extensions under this Rule in
easements or rights-of-way where final grades have not been established, or
where street grades have not been brought to those established by public
authority. If extensions are made when grades have not been established and
there is a reasonable probability that the existing grade will be changed, the
utility shall require that the applicant or applicants for the main extension
deposit, at the time of execution of the main extension agreement, the estimated
net cost of relocating, raising, or lowering facilities upon establishment of final
grades. Adjustment of any difference between the amount so deposited and the
actual cost of relocating, raising, lowering facilities shall be made within ten (10)
days after the utility has ascertained such actual cost. The net deposit
representing actual cost is not subject to refund. The entire deposit related to the
proposed relocation, raising or lowering shall be refunded when such
displacements are determined by proper authority to be not required.
2. Definitions
a. Bona Fide Customer, for the purposes of this Rule, shall be a customer (excluding
any customer formerly served at the same location) who has given satisfactory
evidence that service will be reasonably permanent to the property which has
been improved with a building of permanent nature and to which service has
commenced. The provision of service to a real estate developer or builder during
the construction or development period shall not establish him as a bona fide

same side thereof as the property of the applicant and the estimated and
adjusted construction costs in such case shall be based upon such an extension.
d. When an extension must comply with an ordinance, regulation, or specification of
public authority, the estimated and adjusted construction costs of said extension
