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

general rate case to modify, extend, or discontinue the same ECRM, pursuant to
the procedures in 4 CSR 240-2.135 for handling
confidential information, including any commission order issued
thereunder.
(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.
