Mo. Code Regs. tit. 20 § 4240-3.162

Current through Register Vol. 49, No. 21, November 1, 2024.

Section 20 CSR 4240-3.162 - Electric Utility Environmental Cost Recovery Mechanisms Filing and Submission Requirements

PURPOSE: This rule implements the provisions of Senate Bill 179, codified at section 386.266, RSMo Supp. 2008, which permits the commission to authorize the inclusion of an environmental cost recovery mechanism in utility rates.

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

(A) EFIS means the electronic filing and information system of the commission;

(B) Electric utility means electrical corporation as defined in section 386.020, RSMo, subject to commission regulation pursuant to Chapters 386 and 393, RSMo;

(C) Environmental compliance plan means a twenty (20)-year forecast of environmental compliance investments and a detailed four (4)-year plan for complying with federal, state, and local environmental laws, regulations, and rules. The four (4)-year plan will include plans to use emission allowances for compliance, plans for emission allowance transactions, and, on a generation unit basis, plans for investments in emission control equipment. The environmental compliance plan shall be consistent with the implementation plan of the most recent resource plan filing except as otherwise explained by the electric utility. Approval of an Environmental Cost Recovery Mechanism (ECRM) does not imply approval or predetermination of prudence of the environmental compliance plan;

(D) Environmental Cost Recovery Mechanism (ECRM) means a mechanism established in a general rate proceeding that allows periodic rate adjustments, outside a general rate proceeding, to reflect the net increases or decreases in an electric utility's environmental revenue requirement, plus additional environmental costs incurred since the prior general rate proceeding;

(E) Environmental costs means prudently incurred costs, both capital and expense, directly related to compliance with any federal, state, or local environmental law, regulation, or rule.

1. Environmental costs do not include fuel and purchased power costs as defined in 4 CSR 240-3.161(1)(A).

2. Prudently incurred costs do not include any increased costs resulting from negligent or wrongful acts or omissions by the utility;

(F) The environmental revenue requirement shall be comprised of the following:

1. All expensed environmental costs (other than taxes and depreciation associated with capital projects) that are included in the electric utility's revenue requirement in the general rate proceeding in which the ECRM is established; and

2. The costs (i.e., the return, taxes, and depreciation) of any major capital projects whose primary purpose is to permit the electric utility to comply with any federal, state, or local environmental law, regulation, or rule. Representative examples of such capital projects to be included (as of the date of adoption of this rule) are electrostatic precip-itators, fabric filters, nitrous oxide emissions control equipment, and flue gas desulfuriza-tion equipment. The costs of such capital projects shall be those identified on the electric utility's books and records as of the last day of the test year, as updated, utilized in the general rate proceeding in which the ECRM is established;

(G) General rate proceeding means a general rate increase proceeding or complaint proceeding before the commission in which all relevant factors that may affect the costs, or rates and charges, of the electric utility are considered by the commission; and

(H) Rate class is a customer class defined in an electric utility's tariff. Generally, rate classes include Residential, Small General Service, Large General Service, and Large Power Service, but may include additional rate classes. Each rate class includes all customers served under all variations of the rate schedules available to that class.

(2) When an electric utility files to establish an ECRM as described in 4 CSR 240-20.091(2), the electric utility shall file the following supporting information as part of, or in addition to, its direct testimony:

(A) An example of the notice to be provided to customers as required by 4 CSR 240-20.091(2)(E);

(B) An example customer bill showing how the proposed ECRM shall be separately identified on affected customers' bills in accordance with 4 CSR 240-20.091(8);

(G) A complete description of how the proposed ECRM is compatible with the requirement for prudence reviews;

(H) A complete explanation of all the costs that shall be considered for recovery under the proposed ECRM and the specific account used for each cost item on the electric utility's books and records;

(I) A complete explanation of all of the costs, both capital and expense, incurred to comply with any current federal, state, or local environmental law, regulation, or rule that the electric utility is proposing be included in base rates and the specific account used for each cost item on the electric utility's books and records;

(J) A complete explanation of all the revenues that shall be considered in the determination of the amount eligible for recovery under the proposed ECRM and the specific account where each such revenue item is recorded on the electric utility's books and records;

(K) A complete explanation of any feature designed into the proposed ECRM or any existing electric utility policy, procedure, or practice that can be relied upon to ensure that only prudent costs shall be eligible for recovery under the proposed ECRM;

(L) For each of the major categories of costs that the electric utility seeks to recover through its proposed ECRM, a complete explanation of the specific rate class cost allocations and rate design used to calculate the proposed environmental revenue requirement and any subsequent ECRM rate adjustments during the term of the proposed ECRM;

(10) Party status and providing to other parties affidavits, testimony, information, reports, and workpapers in related proceedings subsequent to general rate proceeding establishing ECRM.

(A) A person or entity granted intervention in a general rate proceeding in which an ECRM is approved by the commission shall be a party to any subsequent related periodic adjustment proceeding, annual true-up, or prudence review, without the necessity of applying to the commission for intervention. In any subsequent general rate proceeding, such person or entity must seek and be granted status as an intervenor to be a party to that case. Affidavits, testimony, information, reports, and workpapers to be filed or submitted in connection with a subsequent related periodic adjustment proceeding, annual true-up, prudence review, or general rate case to modify, extend, or discontinue the same ECRM shall be served on or submitted to all parties from the prior related general rate proceeding and on all parties from any subsequent related periodic adjustment proceeding, annual true-up, prudence review, or general rate case to modify, extend, or discontinue the same ECRM, concurrently with filing the same with the commission or submitting the same to the manager of the auditing department of the commission and OPC, pursuant to the procedures in 4 CSR 240-2.135 for handling confidential information, including any commission order issued thereunder.

(B) A person or entity not a party to the general rate proceeding in which an ECRM is approved by the commission may timely apply to the commission for intervention, pursuant to 4 CSR 240-2.075(2) through (4) of the commission's rule on intervention, respecting any related subsequent periodic adjustment proceeding, annual true-up, or prudence review, or, pursuant to 4 CSR 240-2.075(1) through (5), respecting any subsequent general rate case to modify, extend, or discontinue the same ECRM. If no party to a subsequent periodic adjustment proceeding, annual true-up, or prudence review objects within ten (10) days of the filing of an application for intervention, the applicant shall be deemed as having been granted intervention without a specific commission order granting intervention, unless within the above-referenced ten (10)-day period the commission denies the application for intervention on its own motion. If an objection to the application for intervention is filed on or before the end of the above-referenced ten (10)-day period, the commission shall rule on the application and the objection within ten (10) days of the filing of the objection.

(11) Discovery. The results of discovery from a general rate proceeding where the commission may approve, modify, reject, extend, or discontinue an ECRM, or from any subsequent periodic adjustment proceeding, annual true-up, or prudence review relating to the same ECRM, may be used without a party resubmitting the same discovery requests (data requests, interrogatories, requests for production, requests for admission, or depositions) in the subsequent proceeding to parties that produced the discovery in the prior proceeding, subject to a ruling by the commission concerning any evidentiary objection made in the subsequent proceeding.

(12) Supplementing and updating data requests in subsequent related proceedings. If a party, which submitted data requests relating to a proposed ECRM in the general rate proceeding where the ECRM was established or in the general rate proceeding where the same ECRM was modified or extended, or in any subsequent related periodic adjustment proceeding, annual true-up, or prudence review, wants the responding party to whom the prior data requests were submitted to supplement or update that responding party's prior responses for possible use in a subsequent related periodic adjustment proceeding, annual true-up, prudence review, or general rate case to modify, extend, or discontinue the same ECRM, the party which previously submitted the data requests shall submit an additional data request to the responding party to whom the data requests were previously submitted which clearly identifies the particular data requests to be supplemented or updated and the particular period to be covered by the updated response. A responding party to a request to supplement or update shall supplement or update a data request response from: a related general rate proceeding where a ECRM was established; a general rate case where the same ECRM was modified or extended; or a related periodic adjustment proceeding, annual true-up, or prudence review, which the responding party has learned or subsequently learns is in some material respect incomplete or incorrect.

(13) Separate cases for each general rate proceeding involving an ECRM and for each mutually exclusive twelve (12)-month annual true-up period of an ECRM. Each general rate proceeding where the commission may approve, modify, or reject an ECRM; each general rate case where the commission may authorize the modification, extension, or discontinuance of an ECRM; and each mutually exclusive twelve (12)-month period of an ECRM that encompasses an annual true-up, prudence review, and possible periodic adjustments shall comprise a separate case. The same procedures for handling confidential information shall apply, pursuant to 4 CSR 240-2.135, as in the immediately preceding ECRM case for the particular electric utility, unless otherwise directed by the commission on its own motion or as requested by a party and directed by the commission.

(14) New ECRM. For the purposes of this rule, an ECRM, if continued, modified, or extended in a general rate case, even in substantially the form approved in the prior general rate proceeding, shall be considered to be a new distinct ECRM after each general rate proceeding required by section 386.266.4(3), RSMo.

(15) Right to Discovery Unaffected. In addressing certain discovery matters and the provision of certain information by electric utilities, this rule is not intended to restrict the discovery rights of any party.

(16) Waivers. Provisions of this rule may be waived by the commission for good cause shown.

(17) Rule Review. The commission shall review the effectiveness of this rule by no later than December 31, 2011, and may, if it deems necessary, initiate rulemaking proceedings to revise this rule.
