           APPEAL FROM THE PUBLIC SERVICE COMMISSION

         BEFORE DIVISION ONE: MARK D. PFEIFFER, PRESIDING JUDGE,
             LISA WHITE HARDWICK AND GARY D. WITT, JUDGES
      The Office of the Public Counsel appeals from the Missouri Public Service

Commission's order approving the request of Liberty Energy (Midstates) Corp. d/b/a/

Liberty Utilities ("Liberty") to change its Infrastructure System Replacement Surcharge

("ISRS"). Public Counsel contends the Commission's order is unlawful because it

allows Liberty to recover costs that are not authorized by the ISRS statutes. For

reasons explained herein, we affirm.



                          FACTUAL AND PROCEDURAL HISTORY
        The Commission is the state administrative agency responsible for regulating

public utilities, including gas corporations, in Missouri. In re Laclede Gas Co., 417

S.W.3d 815, 817 (Mo. App. 2014). Liberty is a Missouri corporation and a natural gas

provider. It is a "gas corporation" and "public utility" under Sections 386.020(18) and

(43), RSMo Cum. Supp. 2013,1 and, therefore, is subject to the Commission's

regulatory power. Id. Public Counsel is a state agency that has the discretion to

represent the interests of consumers in all utility proceedings before the Commission

and in all appeals of Commission orders. Id.

        In 2012, Liberty purchased substantially all of the assets that Atmos Energy

Corporation ("Atmos") used to provide natural gas and transportation services in

Missouri. The Commission issued new certificates of convenience and necessity to

Liberty for the service areas formerly served by Atmos, and the Commission approved

Liberty's adoption of Atmos's tariffs.

        Among the tariffs that Liberty adopted were Atmos's ISRS tariffs for each of its

three rate districts. The ISRS statutes, Sections 393.1009, 393.1012, and 393.1015,

provide a method for gas corporations to recover eligible infrastructure system

replacement costs between general rate cases through a surcharge on their customers'

bills. Section 393.1009(3) defines "eligible infrastructure system replacements" as gas

utility plant projects that:

        (a) Do not increase revenues by directly connecting the infrastructure
        replacement to new customers;

        (b) Are in service and used and useful;

       (c) Were not included in the gas corporation's rate base in its most recent
       general rate case; and

       (d) Replace or extend the useful life of an existing infrastructure[.]

Section 393.1009(5) defines "gas utility plant projects," in pertinent part, as:

              (a) Mains, valves, service lines, regulator stations, vaults, and other
       pipeline system components installed to comply with state or federal
       safety requirements as replacements for existing facilities that have worn
       out or are in deteriorated condition;

             (b) Main relining projects, service line insertion projects, joint
       encapsulation projects, and other similar projects extending the useful life
       or enhancing the integrity of pipeline system components undertaken to
       comply with state or federal safety requirements[.]

       In July 2013, Liberty filed a petition with the Commission to change its ISRS to

recover costs incurred due to infrastructure system replacements that Liberty made

from June 1, 2012 through May 31, 2013. Pursuant to Section 393.1015.2(1), when a

petition to establish or change an ISRS is filed, the Commission is required to conduct

an examination of the proposed ISRS. The Commission's Staff may examine the

petitioning gas corporation's information to confirm that the costs are in accordance with

the ISRS statutes and that the proposed charges are properly calculated. §

393.1015.2(2). Staff may then submit a report of its examination to the Commission no

later than sixty days after the petition was filed. Id. The Commission may hold a

hearing on the petition and must "issue an order to become effective not later than one

hundred twenty days after the petition [was] filed." § 393.1015.2(3).

       In this case, Staff from the Commission's Auditing and Energy Units conducted

an investigation of Liberty's ISRS petition. Liberty sought to recover costs for 275

distinct projects. Of these 275 projects, Staff's investigation included reviewing 36




                                              3
Liberty work orders totaling approximately $2.2 million, which was about 58% of the

amount that Liberty requested in its ISRS petition.2

        The work orders that Staff examined provided enough information to

demonstrate that the projects involved replacement of steel or polyethylene pipe. Some

projects included the installation of either gas safety valves or excess flow valves. The

work orders noted the age of the pipe being replaced and any corrosion or other

defects. Staff determined that the work orders involved pipe replacements that

improved the integrity of the system, rather than maintenance expenses, such as

merely wrapping a pipe.

        Additionally, Staff reviewed Liberty's project sub-ledger, which designated

whether a project included material, supplies, overhead, or labor, and whether the

project was performed for the integrity of the system or for growth. The costs included

in the project sub-ledger were detailed enough for Staff to understand the activities and

costs incurred for each job.

        In reviewing Liberty's initial calculations, Staff noticed that Liberty had included

some growth projects, which are not eligible for recovery in an ISRS under Section

393.1009(3)(a). Staff removed those projects when it performed its own calculations.

Staff also identified other errors and omissions in the data provided by Liberty, including

summation errors; errors in accumulated depreciation, deferred income taxes, property

taxes, depreciation rates, and conversion factors; and formula errors. Staff filed a

report, with two subsequent updates, recommending several adjustments to Liberty's

ISRS petition to correct the identified errors and omissions. Staff then calculated an

significantly more project work orders because Staff has more time to conduct its investigation in a
general rate case.

                                                     4
adjusted ISRS. Liberty agreed with Staff's recommendations and calculations in the

adjusted ISRS.

       Public Counsel filed a motion requesting that the Commission reject Liberty's

ISRS petition or schedule an evidentiary hearing. In its motion, Public Counsel

asserted, among other things, that Liberty was seeking to recover expenses in its

proposed ISRS that were not authorized by Section 393.1009(5).

       The Commission held an evidentiary hearing, and the parties argued their

positions in post-hearing briefs. One of the arguments that Public Counsel made was

that Liberty should not be allowed to recover its expenses for infrastructure that was

replaced because it was accidentally or negligently damaged by a third party, such as a

when a contractor accidentally struck a main or service line while digging. Public

Counsel contended that the replacement of a pipe that was accidentally damaged

during excavation activity did not satisfy Section 393.1009(5)(a)'s requirement that the

replacement was for "existing facilities that have worn out or are in deteriorated

condition." (Emphasis added.)

       The Commission rejected this argument, however, and approved Liberty's ISRS

petition as corrected by Staff's adjusted ISRS. In its report and order, the Commission

noted that the term "deteriorated" was commonly defined as "to lower in quality,

character, or value." Applying this definition, the Commission concluded that a pipe that

has been damaged by a third party is in deteriorated condition "because it has been

lowered in quality, character, or value, although that deterioration has occurred quicker

than what happens normally through the passage of time." Therefore, the Commission

determined that Liberty's projects replacing pipes that were damaged by a third party



                                             5
qualified as "gas utility projects" under Section 393.1009(5)(a). Additionally, the

Commission found that those projects qualified as "gas utility projects" under Section

393.1009(5)(b), because they were "projects extending the useful life or enhancing the

integrity of pipeline system components."

       Having found that the ISRS projects remaining after Staff's calculation of the

adjusted ISRS were "gas utility projects," the Commission further found that the projects

were "eligible infrastructure system replacements" under Section 393.1009(3).

Specifically, the Commission found that the projects did not increase revenues by

directly connecting to new customers; were in service, used, and useful; were not

included in Liberty's rate base in its most recent general rate case; and replaced or

extended the useful life of an existing infrastructure.

       In determining the amount of the ISRS to authorize, the Commission noted that

Public Counsel did not present any evidence that Staff's adjusted ISRS calculations

were incorrect and that Public Counsel did not make its own ISRS calculations. The

Commission also found that Staff's witnesses were more credible than Public Counsel's

witness regarding the evaluation of Liberty's ISRS request because the testimony of

Staff's witnesses was more detailed and precise. The Commission, therefore,

authorized a change to Liberty's ISRS to allow it to recover revenues of $572,662, which

was the amount proposed in Staff's adjusted ISRS.

       Liberty filed a new ISRS tariffs in compliance with the Commission's order, and

the Commission approved the tariffs. Public Counsel filed an amended application for

rehearing, which the Commission denied. Public Counsel appeals.

                                              6
       Appellate review of the Commission's order is limited to determining whether it is

lawful and reasonable. State ex rel. MoGas Pipeline, LLC v. Pub. Serv. Comm'n, 366

S.W.3d 493, 495-96 (Mo. banc 2012). An order is lawful if the Commission acted within

its statutory authority. State ex rel. Sprint Mo., Inc. v. Pub. Serv. Comm'n, 165 S.W.3d

160, 164 (Mo. banc 2005). The Commission's order "has the presumption of validity."

Id. An order is reasonable if it is supported by substantial, competent evidence, it is not

arbitrary or capricious, and the Commission has not abused its discretion. State ex rel.

Praxair, Inc. v. Pub. Serv. Comm'n, 344 S.W.3d 178, 184 (Mo. banc 2011).

                                         ANALYSIS

       In its sole point on appeal, Public Counsel contends the Commission's order is

unlawful and unreasonable because it allows Liberty to recover costs through the ISRS

that are not authorized by the ISRS statutes. Specifically, Public Counsel argues that

the Commission erred in finding that Liberty's projects replacing pipes that were

damaged by a third party are "gas utility plant projects" under Section 393.1009(5)(a):

       (a) Mains, valves, service lines, regulator stations, vaults, and other
       pipeline system components installed to comply with state or federal
       safety requirements as replacements for existing facilities that have worn
       out or are in deteriorated condition[.]

(Emphasis added.) Public Counsel asserts that the Commission erroneously

interpreted the phrase "are in deteriorated condition" to include pipes that have been

damaged by third parties. Public Counsel insists that the reference to facilities in

"deteriorated condition" includes only those facilities whose quality has been gradually

lowered over time, rather than facilities that have been destroyed or damaged

immediately through a third party's accident or negligence.




                                             7
         The interpretation of a statute is a matter of law, which this court reviews de

novo. Laclede, 417 S.W.3d at 819. While the "'interpretation and construction of a

statute by an agency charged with its administration is entitled to great weight,'" we

"exercise[ ] independent judgment and must correct erroneous interpretations of law."

Sprint Mo., 165 S.W.3d at 164 (quoting Foremost-McKesson, Inc. v. Davis, 488 S.W.2d

193, 197 (Mo. banc 1972)).

         Our goal in interpreting Section 393.1009(5)(a) is to ascertain the legislature's

intent from the language used and give effect to that intent, if possible. Laclede, 417

S.W.3d at 820. If the legislature's intent is "clear and unambiguous, then we are bound

by that intent." Id. "We 'look beyond the plain meaning of the statute only when the

language is ambiguous or will lead to an absurd or illogical result.'" Id. (citation

omitted).

         In considering whether Section 393.1009(5)(a)'s reference to facilities that "are in

deteriorated condition" includes those that have been damaged by third parties, we note

that the term "deteriorated" is not defined in Chapter 393. Where no statutory definition

exists, we are to give statutory terms "'their plain and ordinary meaning as derived from

the dictionary.'" MoGas Pipeline, 366 S.W.3d at 498 (citation omitted).

         The dictionary definition of the term "deteriorate" is: "to make inferior in quality or

value:   IMPAIR";   "to grow worse"; "become impaired in quality, state, or condition:

DEGENERATE."        W EBSTER'S THIRD NEW INTERNATIONAL DICTIONARY OF THE ENGLISH

LANGUAGE UNABRIDGED 616 (1993). Applying this definition to Section 393.1009(5)(a),

facilities that are in "deteriorated" condition are those that have been made inferior or

become impaired in quality, state, or value. While the term "deteriorated" may also



                                                8
describe diminution or impairment that has occurred gradually over time, as evidenced

by the alternative meaning "to grow worse," the definition is not restricted to describing

only diminution or impairment that has occurred over time. Rather, "deteriorated" is

broadly defined, allowing the Commission latitude in deciding whether costs are

recoverable under this section.

        Because pipes that have been damaged by a third party are facilities that have

been made inferior or become impaired in quality, state, or value, they constitute

facilities that the Commission could have properly determined to be in "deteriorated"

condition under the plain language of Section 393.1009(5)(a). Therefore, the

Commission's decision to allow Liberty to recover its costs, through the ISRS, for

projects replacing such facilities is lawful and reasonable.3 Public Counsel's point is

denied.

  During oral argument, the issue was raised as to whether allowing Liberty to use the ISRS to recover its
costs to replace pipes damaged by a third party's or its own employees' negligence would lead to a
double recovery for Liberty, because either the third party or insurance presumably would compensate
Liberty for those costs. First, we note that the Commission's decision, and, in turn, this appeal, concern
only the recovery of costs for damage caused by a third party, not damage caused by Liberty's
employees. Second, Public Counsel addressed the double recovery issue before the Commission. In its
response to Public Counsel's concerns, Liberty stated in its post-hearing brief that it credits any
compensation received from either third parties or insurance to the relevant project number. Liberty
explained that, if the recovery occurs before an ISRS filing, it is reflected in the ISRS filing. If the recovery
occurs after the ISRS filing, then it is reflected in the true-up in the rate case. This is consistent with the
ISRS statutes, which provide that the Commission is not bound by its approval of an ISRS and, during a
subsequent general rate proceeding, may "undertake to review the prudence of such costs."
§ 393.1015.8. See also § 393.1015.9 (stating that "[n]othing in this section 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 any gas corporation"). Section 393.1015.8 further
provides that, "[i]n the event the commission disallows, during a subsequent general rate proceeding,
recovery of costs associated with eligible infrastructure system replacements previously included in an
ISRS, the gas corporation shall offset its ISRS in the future as necessary to recognize and account for
any such overcollections." These statutory provisions guard against any double recovery by the gas
corporation.
