Current through Register Vol. 49, No. 6, March 15, 2024

PURPOSE: This rule sets forth the definitions, parameters and procedures relevant to the filing and processing of petitions pertaining to an infrastructure system replacement surcharge (ISRS), including the information that an eligible water utility must provide when it files a petition and associated rate schedules to establish, change or reconcile an ISRS.

(1) As used in this rule, the following terms mean:

(A) Appropriate pretax revenues-the revenues necessary to:
1. Produce net operating income equal to the eligible water utility's weighted cost of capital multiplied by the net original cost of eligible infrastructure system replacements (original cost of eligible infrastructure system replacements, net of accumulated deferred income taxes and accumulated depreciation associated with the replacements), including recognition of accumulated deferred income taxes and accumulated depreciation associated with eligible infrastructure system replacements that are included in a currently effective ISRS;

2. Recover state, federal, and local income or excise taxes applicable to such income; and

3. Recover all other ISRS costs;

(B) Eligible infrastructure system replacements-water utility plant projects that:
1. Replace or extend the useful life of existing infrastructure;

2. Are in service and used and useful;

3. Do not increase revenues by directly connecting the infrastructure replacement to new customers;

4. Were not included in the eligible water utility's rate base in its most recent general rate case; and

5. Were made in a county with a charter form of government and with more than one
(1) million inhabitants;

(C) Eligible water utility-a water corporation as defined in section 386.020(58), RSMo, that provides service to more than ten thousand (10,000) customers in a county with a charter form of government and with more than one (1) million inhabitants;

(D) ISRS-infrastructure system replacement surcharge;

(E) ISRS costs-annual depreciation expenses, and property taxes that will be due within twelve (12) months of the ISRS filing, on the total cost of eligible infrastructure system replacements, reduced by annual depreciation expenses and property taxes on any related facility retirements;

(F) ISRS revenues-revenues produced through an ISRS, exclusive of revenues from all other rates and charges;

(G) Water utility plant projects-projects that consist only of the following:
1. Mains, and associated valves and hydrants, installed as replacements for existing facilities that have worn out or are in deteriorated condition;

2. Main cleaning and relining projects; and

3. Facilities relocations required due to construction or improvement of a highway, road, street, public way, or other public work by or on behalf of the United States, this state, a political subdivision of this state or another entity having the power of eminent domain; provided that the costs related to such projects have not been reimbursed to the eligible water utility.

(2) Pursuant to the provisions of this rule and sections 393.1000 to 393.1006, RSMo, an eligible water utility may file a petition with the commission to establish or change ISRS rate schedules that will allow for the adjustment of its rates and charges to provide for the recovery of costs for eligible infrastructure system replacements; provided that an ISRS, on an annualized basis, must produce ISRS revenues of at least one (1) million dollars but not in excess of ten percent (10%) of the subject utility's base revenue level approved by the commission in the utility's most recent general rate proceeding.

(3) An ISRS, and any future changes thereto, shall be calculated and implemented in accordance with the provisions of this rule and sections 393.1000 to 393.1006, RSMo.

(4) ISRS revenues shall be subject to refund based upon a finding and order of the commission, to the extent provided in subsections 5 and 8 of section 393.1006, RSMo.

(5) The commission shall not approve an ISRS for an eligible water utility that has not had a general rate proceeding decided or dismissed by issuance of a commission order within the past three (3) years, unless that utility has filed for or is the subject of a new general rate proceeding.

(6) In no event shall an eligible water utility collect an ISRS for a period exceeding three (3) years unless it has filed for or is the subject of a new general rate proceeding; provided that the ISRS may be collected until the effective date of new rate schedules established as a result of the new general rate proceeding, or until the subject general rate proceeding is otherwise decided or dismissed by issuance of a commission order without new rates being established.

(7) Upon the filing of a petition seeking to establish or change an ISRS, the commission will publish notice of the filing.

(8) The eligible water utility shall provide the following notices to its customers, with such notices to be approved by the commission in accordance with section (9) of this rule before they are sent to the customers:

(A) An initial, one (1)-time notice to all potentially affected customers, with such notice to be sent to customers no later than when customers will receive their first bill that includes an ISRS, explaining the subject utility's infrastructure system replacement program, explaining how its ISRS will be applied to its various customer classes and identifying the statutory authority under which it is implementing its ISRS;

(B) An annual notice to affected customers each year that an ISRS is in effect explaining the continuation of its infrastructure system replacement program and the resulting ISRS; and

(C) A surcharge description on all affected customer bills, which informs the customers of the existence and amount of the ISRS on the bills.

(9) Within twenty (20) days of the eligible water utility's filing of a petition to establish an ISRS, the subject utility shall submit the following items to the commission for approval or rejection, and the office of the public counsel may, within ten (10) days of the water utility's filing, submit comments regarding these items to the commission:

(A) An example of the notice required by subsection (8)(A) of this rule;

(B) An example of the notice required by subsection (8)(B) of this rule; and

(C) An example customer bill showing how the ISRS will be described on affected customers' bills in accordance with subsection (8)(C) of this rule.

(10) When an eligible water utility files a petition pursuant to the provisions of this rule and sections 393.1000 to 393.1006, RSMo, the commission shall conduct an examination of the proposed ISRS.

(11) The staff of the commission may examine the information the eligible water utility provides pursuant to the provisions of this rule and sections 393.1000 to 393.1006, RSMo, to confirm the underlying costs related to and the proper calculation of the proposed ISRS, and may submit a report regarding its examination to the commission not later than sixty (60) days after the eligible water utility files its petition. The staff shall not examine any other revenue requirement or ratemaking issues in its consideration of the petition or associated proposed rate schedules.

(12) The commission may hold a hearing on the petition and the associated proposed rate schedules, and shall issue an order to become effective not later than one hundred twenty (120) days after the eligible water utility files the petition.

(13) If the commission finds that a petition complies with the requirements of sections 393.1000 to 393.1006, RSMo, the commission shall enter an order authorizing the eligible water utility to impose an ISRS that is sufficient to recover appropriate pretax revenues, as determined by the commission.

(14) Commission approval of a petition, and any associated rate schedules, to establish or change an ISRS pursuant to sections 393.1000 to 393.1006, RSMo, shall in no way be binding upon the commission in determining the ratemaking treatment to be applied to eligible infrastructure system replacements during a subsequent general rate proceeding when the commission may undertake to review the prudence of such costs. In the event the commission disallows recovery of costs associated with eligible infrastructure system replacements previously collected through an ISRS, as a part of its order in a subsequent general rate proceeding, the water utility shall offset its ISRS in the future as needed to recognize and account for any such disallowances. Nothing in this rule or section 393.1006, RSMo, shall be construed as limiting the authority of the commission to review and consider infrastructure system replacement costs along with other costs during any general rate proceeding of an eligible water utility.

(15) An eligible water utility may effectuate a change in an ISRS no more often than two (2) times during every twelve (12)-month period, with the first such period beginning on the effective date of the rate schedules that establish an initial ISRS. For the purposes of this section, an initial ISRS is the first ISRS granted to the subject utility or an ISRS established after an ISRS is reset to zero pursuant to the provisions of section (17) of this rule.

(16) At the end of each twelve (12)-month period that an ISRS is in effect, the eligible water utility shall reconcile the differences between the revenues resulting from the ISRS and the appropriate pretax revenues as found by the commission for that period, and shall submit the reconciliation and proposed ISRS rate schedule revisions to the commission for approval to recover or refund the difference, as appropriate.

(17) An eligible water utility that has implemented an ISRS shall file revised ISRS rate schedules to reset the ISRS to zero when new base rates and charges become effective following a commission order establishing customer rates in a general rate proceeding that incorporates eligible costs previously reflected in an ISRS into the subject utility's base rates. If an over or under recovery of ISRS revenues, including any commission ordered refunds, exists after the ISRS has been reset to zero, the amount of over or under recovery shall be tracked in an account and considered in the water utility's next ISRS filing that it submits pursuant to the provisions of section (2) of this rule.

(18) Upon the inclusion of eligible costs previously reflected in an ISRS in an eligible water utility's base rates, the subject utility shall immediately thereafter reconcile any previously unreconciled ISRS revenues as necessary to ensure that revenues resulting from the ISRS match, as closely as possible, the appropriate pretax revenues as found by the commission for that period, and shall track such revenues pursuant to the provisions of section (17) of this rule.

(19) At the time that an eligible water utility files a petition with the commission seeking to establish, change or reconcile an ISRS, it shall submit proposed ISRS rate schedules and its supporting documentation regarding the calculation of the proposed ISRS with the petition, and shall serve the office of the public counsel with a copy of its petition, its proposed rate schedules and its supporting documentation. The subject utility's supporting documentation shall include workpapers showing the calculation of the proposed ISRS, and shall include, at a minimum, the following information:

(A) The state, federal, and local income or excise tax rates used in calculating the proposed ISRS, and an explanation of the source of and the basis for using those tax rates;

(B) The regulatory capital structure used in calculating the proposed ISRS, and an explanation of the source of and the basis for using that capital structure;

(C) The cost rates for debt and preferred stock used in calculating the proposed ISRS, and an explanation of the source of and the basis for using those cost rates;

(D) The cost of common equity used in calculating the proposed ISRS, and an explanation of the source of and the basis for using that equity cost;

(E) The property tax rates used in calculating the proposed ISRS, and an explanation of the source of and the basis for using those tax rates;

(F) The depreciation rates used in calculating the proposed ISRS, and an explanation of the source of and the basis for using those depreciation rates;

(G) The costs that are eligible for recovery during the period in which the ISRS will be in effect, including the net original cost of the infrastructure system replacements and the amount of ISRS costs related to the eligible replacements; and a breakdown of the eligible replacements identified by work order or cost center for each of the following project categories:
1. Mains, and associated valves and hydrants, installed as replacements for existing facilities that have worn out or are in deteriorated condition;

2. Main cleaning and relining projects;

3. Facilities relocations required due to construction or improvement of a highway, road, street, public way, or other public work by or on behalf of the United States;

4. Facilities relocations required due to construction or improvement of a highway,

road, street, public way, or other public work by or on behalf of this state;

5. Facilities relocations required due to construction or improvement of a highway, road, street, public way, or other public work by or on behalf of a political subdivision of this state; and

6. Facilities relocations required due to construction or improvement of a highway, road, street, public way, or other public work by or on behalf of an entity other than the United States, this state or a political subdivision of this state, having the power of eminent domain;
