    APPEAL FROM THE PUBLIC UTILITIES COMMISSION
    (Docket No. 2017-0122)
    MAY 10, 2019
    RECKTENWALD, C.J., NAKAYAMA, McKENNA, POLLACK, AND WILSON, JJ.
    OPINION OF THE COURT BY RECKTENWALD, C.J.
    This case arises from the Public Utilities Commission’s
    approval of an amended power purchase agreement (Amended PPA)
    between Hawaii Electric Light Company, Inc. (HELCO) and Hu Honua
    Bioenergy, LLC.    Pursuant to the Amended PPA, Hu Honua would
    construct and operate a biomass-fueled energy production
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    facility, and HELCO would purchase energy from the facility.
    Life of the Land (LOL), an environmental nonprofit
    organization, sought to intervene as a party in the PUC’s
    proceeding in order to address the environmental impacts of the
    proposed biomass facility.       The PUC denied LOL full party status,
    but granted LOL limited participation in the proceeding.              The PUC
    ultimately approved the Amended PPA without holding a hearing.
    LOL directly appealed the PUC’s order granting it
    limited participation in the proceeding, as well as the Decision
    and Order approving the Amended PPA (2017 D&O), to this court.
    LOL argues that the PUC:      (1) failed to explicitly consider
    greenhouse gas (GHG) emissions in determining whether to approve
    the Amended PPA, as required by state law; (2) denied LOL due
    process to protect its interest in a clean and healthful
    environment by restricting its participation in the proceeding;
    and (3) abused its discretion and violated due process by denying
    LOL full party status in the proceeding.          In addition to
    disputing these allegations, the PUC, HELCO, and Hu Honua contest
    this court’s jurisdiction over the matter.
    As a threshold matter, we hold that this court has
    jurisdiction to consider LOL’s appeal.          We further hold that the
    PUC erred by failing to explicitly consider the reduction of GHG
    emissions in approving the Amended PPA, as required by statute,
    and that the PUC denied LOL due process with respect to the
    opportunity to be heard regarding the impacts that the Amended
    2
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    PPA would have on LOL’s right to a clean and healthful
    environment.     Finally, we need not resolve whether the PUC abused
    its discretion or deprived LOL of due process by denying it full
    party status in the proceeding.
    Accordingly, we vacate the 2017 D&O and remand this
    matter to the PUC for further proceedings.
    I.   BACKGROUND
    A.    PUC Proceedings
    1.    2012 Docket
    In 2012, HELCO submitted an application to the PUC
    seeking approval of a power purchase agreement (Original PPA)
    with Hu Honua.     Pursuant to the Original PPA, Hu Honua agreed to
    refurbish an existing biomass power plant located on the Hāmākua
    Coast in Pepeekeo, Hawaii, to allow it to utilize harvested
    timber and other “woody biomass” as a fuel source.              HELCO agreed
    to purchase energy from the facility over the Original PPA’s 20-
    year term.
    LOL filed a Motion to Intervene as a party-intervenor
    in the PUC proceeding (2012 Docket), pursuant to Hawaii
    Administrative Rules (HAR) § 6-61-55 (effective 1992-2018).1                  In
    1
    We note that HAR title 6, chapter 61 - Rules of Practice and
    Procedure Before the Public Utilities Commission (effective 1992-2018) - was
    repealed on January 1, 2019. It was replaced by HAR title 16, chapter 601
    (effective Jan. 1, 2019). All of the repealed administrative rules referenced
    in this opinion have been replaced by identical rules that remain in effect.
    HAR § 6-61-55 (effective 1992-2018) has been replaced by HAR § 16-601-55
    (effective Jan. 1, 2019). See infra note 22.
    3
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    its motion, LOL explained that it is a Hawaii-based nonprofit
    organization comprised of members who live, work, and recreate in
    Hawaii.    LOL highlighted its environmental interests and
    explained that the externalities associated with the use of
    biofuels for energy production “[can] be very harmful to [its]
    interests.”    LOL also stated it “has developed great expertise in
    biofuels” and has demonstrated its expertise in several
    regulatory proceedings regarding biofuels.
    More specifically, with regard to the proposed Hu Honua
    facility, LOL stated it had “several concerns, including the fuel
    source, the comparative cost, . . . [and whether] this proposed
    facility will cut into the utilities[’] purchase of energy from
    existing and/or planned wind and solar farms.”            Finally, LOL
    stated it had “unique environmental interests different from the
    general public,” and assured the PUC that its intent was “not to
    disrupt the process[,] but . . . to insure that [LOL’s] members
    and our local environmental communities have a voice in this
    process.”
    The PUC found that the “concerns raised in [LOL’s]
    Motion to Intervene provide[d] insufficient basis to justify full
    intervention[.]”    However, it also found that “LOL’s concerns
    regarding the proposed project’s impact on existing renewable
    projects on the Big Island, and the supply and pricing analysis
    between the biomass resources delineated in the [Original] PPA
    [were] sufficient to justify LOL having limited participant
    4
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    status in [the 2012 Docket], pursuant to HAR § 6-61-56.”
    Accordingly, the PUC denied LOL’s motion, but granted it “limited
    participant status” sua sponte, allowing it to participate with
    respect to:   (1) whether the energy price components properly
    reflect the cost of biomass fuel supply; and (2) whether HELCO’s
    purchase power arrangements under the Original PPA are prudent
    and in the public interest.
    The PUC ultimately approved the Original PPA, but HELCO
    subsequently terminated the agreement.          HELCO and Hu Honua agreed
    to amend the Original PPA, giving rise to the Amended PPA at
    issue in the instant case.
    2.   2017 Docket
    In 2017, HELCO filed an application with the PUC,
    seeking approval of the Amended PPA.         The PUC entered Order No.
    34554, opening Docket No. 2017-0122 (2017 Docket) to address
    HELCO’s request.    The order also granted LOL “conditional
    participant status” in the proceeding and stated it would
    reevaluate LOL’s status and establish the scope of LOL’s
    participation following its final determination of the issues
    governing the 2017 Docket.
    LOL filed exhibits in response to Order No. 34554,
    which included an overview of the “agricultural expertise” of
    Henry Curtis, LOL’s Vice President of Consumer Issues.              Curtis
    explained that he had “stayed with friends living in Hamakua,
    stayed at vacation sites in Hamakua, explored Hamakua, and made
    5
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    several trips to the Hu Honua site, driving around three sides of
    the site.”2    In support of his agricultural expertise, Curtis
    also cited to a chapter that he authored in “The Value of
    Hawaii:   Knowing the Past, Shaping the Future,” which cites
    runoff into the ocean as one of the primary adverse environmental
    impacts associated with the use of biofuels for energy
    production.
    The PUC entered Order No. 34597, establishing a
    procedural schedule, statement of the issues, and scope of
    participation for participants.         The PUC permitted LOL to
    participate in the proceeding, but limited the scope of its
    participation to the same two issues that it participated on in
    the 2012 Docket:
    2.a.i. Whether the energy price components in the
    Amended and Restated PPA properly reflect the cost of
    biomass fuel supply.
    2.b. Whether HELCO’s purchase power arrangements under
    the Amended and Restated PPA are prudent and in the
    public interest.
    Specifically, the PUC found that:
    Because the question of whether HELCO’s purchase power
    arrangements under the Amended and Restated PPA are
    prudent and in the public interest continues to be an
    issue in this proceeding, as it was in Docket No.
    2012-0212, the commission finds it appropriate to
    maintain LOL, Tawhiri, and HEP’s participant status on
    2
    It appears Curtis was referring to the Big Island’s Hāmākua Coast,
    of which Pepeekeo is a part.
    6
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    this issue (Issue 2.b., above).3 Further, while not
    explicitly stated, the question of whether the energy
    price components properly reflect the cost of biomass
    fuel supply is a consideration when determining
    whether the purchased power costs to be paid by HELCO
    pursuant to the Amended and Restated PPA are
    reasonable (Issue 2.a., above). Accordingly, the
    commission finds it appropriate to maintain LOL's
    participant status on the specific sub-issue of
    whether the energy price components properly reflect
    the cost of biomass fuel supply (Issue 2.a.i., above).
    (Emphasis added).
    a.    Motion to Upgrade Status
    LOL filed a Motion to Upgrade Status, requesting that
    the PUC allow it to intervene in the 2017 Docket as a party.4                 In
    support of its Motion to Upgrade Status, LOL stressed the fact
    that the PUC had already “grant[ed] LOL participant status based
    on [its] interests in the pending matter.”            LOL also cited
    previous PUC proceedings in which it was admitted as a party, and
    stated that: (1) its Board of Directors “approved continuing to
    intervene in energy dockets as a means of promoting sustainable
    policies”; (2) LOL’s members “are very deeply concerned about
    climate change, biodiversity, and the spread of invasive
    species”; (3) the only way to protect LOL’s interest is by
    3
    Tawhiri Power, LLC (Tawhiri) and Hamakua Energy Partners (HEP)
    were granted participant status in the 2017 Docket only with regard to Issue
    2.b. LOL, Tawhiri, and HEP all filed motions to intervene in the 2012 Docket,
    which were denied. They were instead granted limited participant status.
    4
    Although LOL did not cite HAR § 6-61-55 as the relevant authority
    for its Motion to Upgrade Status, the motion nevertheless touches upon each of
    the nine requirements for motions for intervention under HAR § 6-61-55(b)
    (effective 1992 to 2018). HAR § 16-601-55(b) (effective Jan. 1, 2019)
    contains the same nine requirements. See infra, note 22.

    accessing “classified documents dealing with externalities”; (4)
    there are no other means available to protect LOL’s interests;
    (5) the Consumer Advocate does not represent LOL’s interests
    because it lacks the expertise to understand externalities;5 (6)
    the agricultural expertise of LOL’s vice president will assist in
    developing an evidentiary record; and (7) while the Consumer
    Advocate represents the interests of the general public, “LOL is
    concerned with a wider lens that encompasses externalities
    including social justice, environmental justice, climate justice,
    and [GHG] impacts.”      In addition, LOL specifically expressed
    5
    Pursuant to Hawaii Revised Statutes (HRS) § 269–51 (Supp. 2018)
    and HAR § 16–601–62 (effective Jan. 1, 2019), the Consumer Advocate represents
    the consumer and may participate as an ex officio party in Commission
    proceedings.
    HRS § 269–51 provides:
    The executive director of the division of consumer
    advocacy shall be the consumer advocate in hearings
    before the public utilities commission. The consumer
    advocate shall represent, protect, and advance the
    interests of all consumers, including small
    businesses, of utility services.
    The responsibility of the consumer advocate for
    advocating the interests of the consumer of utility
    services shall be separate and distinct from the
    responsibilities of the public utilities commission
    and those assistants employed by the commission. The
    consumer advocate shall have full rights to
    participate as a party in interest in all proceedings
    before the public utilities commission.
    HAR § 16–601–62 provides, in pertinent part:
    (a)   The consumer advocate is, ex officio, a party to
    any proceeding before the commission. . . .
    (b)   The consumer advocate shall further apprise the
    commission and the parties of record of any
    facts which relate to the protection or
    advancement of the consumer interest.

    concern regarding the externalities associated with “acquiring
    bioenergy crops” from a specific area of the Big Island that
    already serves as a source for another biofuel facility.
    The PUC issued Order No. 34651, denying LOL’s motion.
    The PUC cited HAR § 6-61-55, specifically noting subsection (d),6
    and stated that “intervention is not a guaranteed right of a
    movant, but is a matter resting within the sound discretion of
    the commission, so long as that discretion is not exercised
    arbitrarily or capriciously.”         It also cited HAR § 6-61-56
    (effective 1992-2018),7 which sets forth the requirements for
    6
    HAR § 6-61-55(d) (effective 1992-2018) provided that “Intervention
    shall not be granted except on allegations which are reasonably pertinent to
    and do not unreasonably broaden the issues already presented.” HAR § 16-601-
    55(d) (effective Jan. 1, 2019) contains identical language. See infra note
    22.
    7
    HAR § 6-61-56 provided:
    (a)   The commission may permit participation without
    intervention. A person or entity in whose
    behalf an appearance is entered in this manner
    is not a party to the proceeding and may
    participate in the proceeding only to the degree
    ordered by the commission. The extent to which
    a participant may be involved in the proceeding
    shall be determined in the order granting
    participation or in the prehearing order.
    (b)   A person who has a limited interest in a
    proceeding may make an application to
    participate without intervention by filing a
    timely written motion in accordance with
    sections 6-61-15 to 6-61-24, section 6-61-41,
    and section 6-61-57.
    (c)   The motion shall provide:
    (1)   A clear and concise statement of the
    direct and substantial interest of the
    applicant;

    participation without intervention.          It stated:
    As was the case in [the 2012 Docket], upon review of
    the record, the commission continues to find that the
    concerns raised in LOL’s Motion, which are identical
    to or mirror the concerns raised by LOL in its Motion
    to Intervene in [the 2012 Docket], provide
    insufficient basis to justify full intervention in
    this proceeding. The commission finds that LOL has
    failed to demonstrate any additional interest or
    expertise sufficient to justify a change in its
    limited participant status granted on a conditional
    basis in Order No. 34554, and permanently established
    pursuant to Order No. 34597.
    b.    Information Requests
    LOL filed several Information Requests (IRs), seeking
    information from HELCO, Hu Honua, and the Consumer Advocate
    regarding GHG emissions and other potential adverse environmental
    impacts of the Hu Honua facility.          In its response to LOL’s IRs,
    HELCO acknowledged that GHGs would be emitted by equipment used

    (2)   The applicant's position regarding the
    matter in controversy;
    (3)   The extent to which the participation will
    not broaden the issues or delay the
    proceeding;
    (4)   The extent to which the applicant's
    interest will not be represented by
    existing parties;
    (5)   A statement of the expertise, knowledge or
    experience the applicant possesses with
    regard to the matter in controversy;
    (6)   Whether the applicant can aid the
    commission by submitting an affirmative
    case; and
    (7)   A statement of the relief desired.
    (Emphasis added). Other than the HAR section numbers it references, HAR 16-
    601-56 (effective Jan. 1, 2019) is identical to HAR 6-61-56 (effective 1992-
    2018).

    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    to raze and transport trees, but stated that it had not
    quantified the amount of emissions.         HELCO asserted that although
    carbon would be released into the atmosphere upon the combustion
    of trees in the facility, it would be recaptured upon the
    regrowth of the trees.      In response to at least one of the IRs
    that LOL submitted to HELCO, HELCO objected and refused to
    respond, arguing that the information sought was “not relevant to
    and [was] outside the scope of LOL’s authorized scope of limited
    participation[.]”
    One of the IRs that LOL submitted to Hu Honua posed
    several questions regarding the quantity of wastewater that would
    be produced by the facility, the means by which it would be
    produced and managed, and the steps that would be taken to
    monitor and prevent ocean contamination.          Hu Honua objected to
    this IR, as well as those focused on GHG emissions and climate
    change, stating that they were “not relevant or material to Issue
    Nos. 2.a.i or 2.b, which [were] the only issues for which the
    Commission authorized LOL’s participation.”
    The Consumer Advocate responded to LOL that it had not
    completed an analysis of the impact the project would have on GHG
    emissions, and that any analysis should be comprehensive,
    including GHGs resulting from harvesting and transporting the
    feedstock.   The Consumer Advocate further stated that it had not
    evaluated the need for a consultant to review GHGs and climate
    change in the instant proceeding.
    11
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    c.     Statements of Position
    In its Statement of Position, LOL argued that Hu
    Honua’s proposed facility was not in the public interest.               LOL
    further argued that Hu Honua’s proposal failed to fully address
    climate change and the environmental impacts of the proposed
    operations.    LOL stated:
    Hu Honua plans to chop down existing trees for seven
    years, and then to rely on a rotational system of
    growing new trees and then chopping them down.
    Omitting any discussion of the fossil fuels used in
    the mechanization of growing, chopping, chipping, and
    transport, Hu Honua alleges that this operation is
    carbon neutral.
    LOL also argued that the pricing of Hu Honua’s proposal
    was not in the public interest when compared to lower-priced
    solar-based electricity proposals previously approved by the PUC.
    In its Reply Statement of Position, Hu Honua argued
    that its facility “will make a significant contribution to the
    State’s [Renewable Portfolio Standards (RPS),]” noting that
    “HELCO estimates that Hu Honua will increase RPS levels by 11%
    over the life of the PPA, and avoid the emission of hundreds of
    thousands of tons of CO2.”      Hu Honua asserted that “the estimated
    emissions due to transportation of fuel to the plant pale in
    comparison to the emissions reductions that will result from the
    displacement of fossil fuel[.]”        Hu Honua further stated that
    “biomass plants, like wind and solar plants, are renewable and
    carbon neutral to a reasonable approximation, and are therefore
    deemed fully renewable by applicable state law.”
    12
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    d.     2017 Decision and Order
    Without holding a hearing, the PUC entered the 2017 D&O
    approving the Amended PPA.       The PUC noted that comments in
    support of the Project focused on issues including the
    fulfillment of the RPS targets and energy resource self-reliance,
    while comments in opposition focused on issues including
    potential adverse environmental impacts, an expected rise in GHG
    emissions, and general objections to biomass as a fuel resource.
    The PUC then summarized each party’s position, citing
    HELCO’s claims that approval of the Amended PPA would be
    reasonable due to, inter alia, the project’s contribution to the
    State’s RPS goals, the fact that the contract price for the
    Amended PPA is de-linked from fossil fuel pricing, and the
    assertion that “renewable energy provided by the Project could
    potentially save approximately 15,700 barrels of fuel per year,
    which over the term of the [Amended] PPA amounts to approximately
    329,000 barrels of fuel oil saved.”         The PUC also noted the
    following:
    HELCO asserted that the totality of circumstances
    should be considered when reviewing whether the
    purchased power costs are reasonable, . . . including
    governmental policies and objectives, contributions
    towards RPS, reducing dependency on fossil fuels,
    decreased price volatility, de-linking energy costs
    from fossil fuel pricing, realization of tax
    incentives, and community benefits.
    . . . .
    LOL asserted that “[t]he cost of biofuel includes both
    financial and non-financial components, which Hu Honua
    has failed to adequately address.” LOL asserted that
    13
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    the “non-financial components” include impacts on
    climate change and endangered species that were not
    explicitly quantified or monetized in HELCO’s
    benefit/cost ratio.
    . . . .
    LOL is not in favor of commission approval of the
    [Amended] PPA, but focused its rationale on concerns
    outside of the scope of its limited participation,
    namely climate change and comparative pricing with
    other forms of energy.
    (Emphases added).
    It appears the PUC adopted HELCO’s analysis of the
    biomass facility’s economic and customer bill impact under the
    Amended PPA, stating, “[p]er HELCO, . . . the Project provides
    significant renewable energy-related benefits, primarily through
    its firm capacity and contribution to the State’s RPS goals.                 For
    the island of Hawaii, with the Project, the RPS goal levels
    increase by approximately 11% over the 30-year life of the
    Project.”    The PUC also made the following findings and
    conclusions:
    [T]he commission finds that the Project will . . . add
    to the diversity of HELCO’s existing portfolio of
    renewable energy resources.
    . . . .
    Consistent with [Hawaii Revised Statutes (HRS)] §
    269-27.2(c)[(Supp. 2016)], the proposed pricing
    structure is delinked from fossil fuel pricing.
    . . . .
    [I]t appears that the addition of the Project may
    primarily displace fossil fuel generation resources.
    Accordingly, the commission anticipates that, based on
    the representations made in HELCO’s [Power Supply
    Improvement Plan], this Project will accelerate the
    14
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    retirement of fossil fuel plants[.]
    (Emphases added).
    The PUC addressed, inter alia, the following two
    issues:   (2.a.i) whether the energy price components in the
    Amended PPA properly reflect the cost of biomass fuel supply; and
    (2.b) whether HELCO’s purchase power arrangements under the
    Amended PPA are prudent and in the public interest.              The PUC
    found the purchased power costs to be reasonable and that the
    arrangements under the Amended PPA were prudent and in the public
    interest.    Accordingly, the PUC approved the Amended PPA,
    concluding that:
    HELCO has met its burden of proof in support of its
    request for the commission to approve the [Amended]
    PPA. The purchased power costs and arrangements set
    forth in the [Amended] PPA appear reasonable, prudent,
    in the public interest, and consistent with HRS
    chapter 269 in general, and HRS § 269-27.2(c), in
    particular. While the commission, in this instance,
    finds the pricing to be reasonable, the commission
    makes clear that its decision to approve the [Amended]
    PPA is not based solely on pricing, but includes other
    factors such as the State’s need to limit its
    dependence on fossil fuels and mitigate against
    volatility in oil pricing.
    (Emphases added).
    B.   Direct Appeal
    LOL directly appealed the PUC’s order denying LOL’s
    Motion to Upgrade Status and the 2017 D&O to this court.               See HRS
    § 269-15.51 (Supp. 2018) and HRS § 91-14 (2012 & Supp. 2018).

    LOL presents three points of error:8          (1) the PUC was required,
    under HRS § 269-6(b) (Supp. 2016), to explicitly consider GHG
    emissions in determining whether the costs of the Amended PPA
    were reasonable, but failed to do so; (2) the PUC denied LOL due
    process to protect its right to a clean and healthful
    environment, as defined by HRS Chapter 269, by restricting its
    participation in the PUC proceedings; and (3) the PUC erred in
    denying LOL’s Motion to Upgrade Status from “participant” to
    “intervenor.”
    II.   STANDARDS OF REVIEW
    A.    Jurisdiction
    “The existence of jurisdiction is a question of law
    that [the appellate court reviews] de novo under the right/wrong
    standard.”    Captain Andy’s Sailing, Inc., v. Dep’t of Land & Nat.
    Res., 113 Hawaii 184, 192, 
    150 P.3d 833
    , 841 (2006) (internal
    quotation marks and citation omitted).
    B.    Direct Appeal
    Because this is a direct appeal from a decision of the
    PUC, the standard of review, as set forth in HRS § 91-14, is as
    follows:
    Upon review of the record, the court may affirm the
    decision of the agency or remand the case with
    instructions for further proceedings; or it may
    reverse or modify the decision and order if the
    8
    LOL did not specifically challenge any findings of fact contained
    in the PUC’s 2017 D&O in its Opening Brief. “Findings of fact . . . that are
    not challenged on appeal are binding on the appellate court.” Bremer v.
    Weeks, 104 Hawaii 43, 63,

    substantial rights of the petitioners may have been
    prejudiced because the administrative findings,
    conclusions, decisions, or orders are:
    (1)     In violation of constitutional or statutory
    provisions;
    (2)     In excess of the statutory authority or
    jurisdiction of the agency;
    (3)     Made upon unlawful procedure;
    (4)     Affected by other error of law;
    (5)     Clearly erroneous in view of the reliable,
    probative, and substantial evidence on the whole
    record; or
    (6)     Arbitrary, or capricious, or characterized by
    abuse of discretion or clearly unwarranted
    exercise of discretion.

    Conclusions of law are reviewed de novo, pursuant to
    subsections (1), (2) and (4); questions regarding
    procedural defects are reviewable under subsection
    (3); findings of fact (FOF) are reviewable under the
    clearly erroneous standard, pursuant to subsection
    (5), and an agency's exercise of discretion is
    reviewed under the arbitrary and capricious standard,
    pursuant to subsection (6). Save Diamond Head Waters

    III.   DISCUSSION
    A.   Jurisdiction
    This court must determine, as a threshold matter,
    whether it has jurisdiction over LOL’s appeal.             Pub. Access
    Shoreline Haw. by Rothstein v. Haw. Cty. Planning Comm’n by
    Fujimoto, 79 Hawaii 425, 431, 
    903 P.2d 1246
    , 1252 (1995)
    (quoting Pele Def. Fund v. Puna Geothermal Venture, 77 Hawaii
    64, 67, 
    881 P.2d 1210
    , 1213 (1994)).          Hu Honua and HELCO argue
    that this court lacks jurisdiction because LOL’s appeal of the
    PUC’s 2017 D&O constitutes an improper collateral attack on the
    PUC’s 2012 D&O.     Additionally, Hu Honua, HELCO, and the PUC argue
    that this court lacks jurisdiction because LOL’s appeal does not
    18
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    arise from a contested case and LOL failed to comply with the
    applicable agency rules by not requesting a contested case
    hearing.
    As set forth below, LOL’s appeal is not a collateral
    attack on the PUC’s 2012 D&O.        LOL has appealed the PUC’s 2017
    D&O to directly challenge its validity, rather than to indirectly
    impeach the validity of the PUC’s 2012 D&O.           Furthermore, the
    requirements for judicial review under HRS § 91-14(a) – a
    contested case hearing, finality, and compliance with agency
    rules – have been satisfied.       The PUC’s 2017 Docket was a
    contested case hearing because a hearing was required by
    constitutional due process in order to consider the impacts of
    approving the Amended PPA on LOL’s right to a clean and healthful
    environment, as defined by HRS Chapter 269, and such a hearing
    would have determined the rights, duties, and privileges of
    HELCO.    It is undisputed that the 2017 D&O is a final decision of
    the PUC.    Finally, LOL followed the applicable agency rules, as
    it was involved in the contested case as a participant in the
    2017 Docket and the PUC’s administrative rules do not require a
    request for a contested case hearing as a prerequisite to
    judicial review.    We therefore have jurisdiction to consider the
    merits of LOL’s appeal.
    1.    Collateral Attack
    “A collateral attack[, as opposed to a direct attack,]
    is an attempt to impeach a judgment or decree in a proceeding not
    19
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    instituted for the express purpose of annulling, correcting or
    modifying such judgment or decree.”            Kapiolani Estate v.
    Atcherly, 
    14 Haw. 651
    , 661 (1903) (citations and internal
    quotation marks omitted).          The ICA has observed that “the
    collateral attack doctrine is implicated when an independent suit
    seeks to impeach a judgment entered in a prior suit.”                 Smallwood
    v. City and Cty. of Honolulu, 118 Hawaii 139, 150, 
    185 P.3d 887
    ,
    898 (App. 2008).        This court has similarly stated that
    “[a]ppellate courts in Hawaii have typically only applied the
    collateral attack doctrine in situations in which a second
    lawsuit has been initiated challenging a judgment or order
    obtained from a prior, final proceeding.”              In re Thomas H. Gentry
    Revocable Tr., 138 Hawaii 158, 169 n.5, 
    378 P.3d 874
    , 885 n.5
    (2016) (citation omitted).
    The party asserting that an action constitutes an
    impermissible collateral attack on a judgment must
    establish that: (1) a party in the present action
    seeks to avoid, defeat, evade, or deny the force and
    effect of the prior final judgment, order, or decree
    in some manner other than a direct post-judgment
    motion, writ, or appeal; (2) the present action has an
    independent purpose and contemplates some other relief
    or result than the prior adjudication; (3) there was a
    final judgment on the merits in the prior
    adjudication; and (4) the party against whom the
    collateral attack doctrine is raised was a party or is
    in privity with a party in the prior action.
    Smallwood, 118 Hawaii at 
    150, 185 P.3d at 898
    .
    As set forth below, LOL’s appeal is a direct attack of
    the PUC’s 2017 D&O, not a collateral attack on the PUC’s 2012
    D&O.
    20
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    The first Smallwood element requires a showing that “a
    party in the present action seeks to avoid, defeat, evade, or
    deny the force and effect of the prior final judgment, order, or
    decree in some manner other than a direct post-judgment motion,
    writ, or appeal.”     118 Hawaii at 
    150, 185 P.3d at 898
    (emphases
    added).   “If an appeal is taken from a judgment, . . . the attack
    is obviously direct, the sole object of the proceeding being to
    deny and disprove the apparent validity of the judgment.”
    Kapiolani 
    Estate, 14 Haw. at 661
    .         Rather than attacking the
    validity of the PUC’s 2012 D&O, LOL’s appeal was instituted for
    the express purpose of denying the force and effect the PUC’s
    2017 D&O.    Thus, the first Smallwood element is not satisfied and
    LOL’s appeal cannot be construed as a collateral attack.
    See Kapiolani 
    Estate, 14 Haw. at 661
    (“A collateral attack is an
    attempt to impeach a judgment or decree in a proceeding not
    instituted for the express purpose of annulling, correcting or
    modifying such judgment or decree.”) (emphasis added).
    Hu Honua and HELCO argue that, even if LOL’s challenge
    appears to be a direct appeal of the PUC’s 2017 D&O, it functions
    as a collateral attack on the PUC’s 2012 D&O.            Hu Honua and HELCO
    contend that the primary purpose of LOL’s appeal is to force the
    PUC to consider the effect of the State’s reliance on fossil
    fuels on GHG emissions and climate change.           However, they argue,
    consideration of GHGs was not within the scope of the PUC’s final
    statement of issues in the 2017 Docket.          According to Hu Honua
    21
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    and HELCO, the 2017 Docket only involved increasing the term of
    the Original PPA and revisions to the contract price and
    milestone events, which do not directly relate to the effect of
    the State’s reliance on fossil fuels on GHG emissions or climate
    change.   Hu Honua and HELCO therefore contend that, to the extent
    the PUC was required to consider the effect of the State’s
    reliance on fossil fuels on GHG emissions and climate change, “it
    did so only in the 2012 Docket.”          Because LOL failed to directly
    and timely challenge the 2012 D&O, Hu Honua and HELCO argue that
    LOL’s appeal is an improper and untimely attempt to raise the
    PUC’s failure to address GHGs in the 2012 D&O.
    As discussed further infra, a majority of this court
    recently determined that “HRS § 269–6(b)’s requirement to reduce
    reliance on fossil fuels and to consider [GHG] emissions applies
    to the fulfillment of all of the [PUC’s] duties.”             In re
    Application of Maui Elec. Co. (MECO), 141 Hawaii 249, 263, 
    408 P.3d 1
    , 15 (2017) (citing HRS § 269–6(b)).           LOL was entitled to
    appeal the PUC’s 2017 D&O due to the PUC’s alleged failure to
    perform statutory and constitutional duties.           Hu Honua and
    HELCO’s argument that the collateral attack doctrine precludes
    this court from exercising appellate jurisdiction over LOL’s
    appeal because the PUC’s consideration of GHGs was outside the
    scope of the 2017 Docket is therefore without merit.
    Accordingly, this court’s appellate jurisdiction is not
    precluded by the collateral attack doctrine.
    22
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    2.   Contested Case
    PUC decisions are appealable to this court pursuant to
    HRS § 269-15.51, which provides, in relevant part:
    Any other law to the contrary notwithstanding,
    including chapter 91, any contested case under this
    chapter shall be appealed from a final decision and
    order or a preliminary ruling that is of the nature
    defined by section 91-14(a) upon the record directly
    to the supreme court for final decision. Only a
    person aggrieved in a contested case proceeding
    provided for in this chapter may appeal from the final
    decision and order or preliminary ruling.
    Judicial review over an agency appeal is authorized by
    HRS § 91-14(a)9 when the following requirements have been met:
    [F]irst, the proceeding that resulted in the
    unfavorable agency action must have been a contested
    case hearing . . . ; second, the agency’s action must
    represent a final decision or order, or a preliminary
    ruling such that deferral of review would deprive the
    claimant of adequate relief; third, the claimant must
    have followed the applicable agency rules and,
    therefore, have been involved in the contested case;
    and finally, the claimant’s legal interests must have
    been injured — i.e., the claimant must have standing
    to appeal.
    MECO, 141 Hawaii at

    (quoting Kilakila O

    Accordingly, there are three jurisdictional

    HRS § 91-14(a) provides, in relevant part:
    Any person aggrieved by a final decision and order in
    a contested case or by a preliminary ruling of the
    nature that deferral of review pending entry of a
    subsequent final decision would deprive appellant of
    adequate relief is entitled to judicial review thereof
    under this chapter; but nothing in this section shall
    be deemed to prevent resort to other means of review,
    redress, relief, or trial de novo, including the right
    of trial by jury, provided by law.
    23
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    requirements for judicial review over an agency appeal: (1) a
    contested case hearing, (2) finality, and (3) compliance with
    agency rules.     
    Id. Hu Honua,
    HELCO, and the PUC argue that this
    court lacks jurisdiction over LOL’s appeal because the appeal
    does not arise from a contested case and LOL failed to comply
    with the applicable agency rules by not requesting a contested
    case hearing.10
    a.    The Proceeding Was a Contested Case Hearing
    “A contested case hearing is one that is (1) required
    by law and (2) determines the rights, duties, and privileges of
    specific parties.”       MECO, 141 Hawaii at 
    258, 408 P.3d at 10
    (internal quotation marks omitted) (citing Kilakila, 131 Hawaii
    at 
    200, 317 P.3d at 34
    ).       As set forth below, the PUC’s 2017
    Docket was a contested case hearing because a hearing was
    required by law that would have determined the rights, duties,
    and privileges of HELCO.
    i.     “Required by Law”
    “In order for an administrative agency hearing to be
    required by law, it may be required by (1) agency rule, (2)
    statute, or (3) constitutional due process.”            
    Id. (internal quotation
    marks omitted) (citing Kilakila, 131 Hawaii at 
    200, 317 P.3d at 34
    ).       LOL contends that a contested case hearing was
    10
    The parties do not dispute that the PUC’s 2017 D&O was a final
    decision or order for the purpose of satisfying the requirements for judicial
    review of an agency appeal. Accordingly, that requirement is not addressed
    further.
    24
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    required under HRS §§ 269-16 (Supp. 2018) and 269-27.2 (2007 &
    Supp. 2018), and constitutional due process.              We hold that
    although a hearing was not required by statute, one was required
    pursuant to constitutional due process.
    (A)   HRS § 269-16(b)
    HRS § 269–16(b) requires the PUC to conduct a contested
    case hearing whenever a utility seeks an increase in rates, but
    specifically exempts rate adjustments “established pursuant to an
    automatic rate adjustment clause previously approved by the
    commission[.]”11      HAR § 6-60-6 (effective June 19, 1981)
    similarly provides that automatic rate adjustment clauses that
    apply to fuel and purchased energy––or fuel adjustment
    11
    HRS § 269-16(b) provides, in relevant part:
    No rate, fare, charge, classification, schedule, rule,
    or practice, other than one established pursuant to an
    automatic rate adjustment clause previously approved
    by the commission, shall be established, abandoned,
    modified, or departed from by any public utility,
    except after thirty days’ notice to the commission as
    prescribed in section 269-12(b), and prior approval by
    the commission for any increases in rates, fares, or
    charges. . . . A contested case hearing shall be held
    in connection with any increase in rates, and the
    hearing shall be preceded by a public hearing as
    prescribed in section 269-12(c), at which the
    consumers or patrons of the public utility may present
    testimony to the commission concerning the increase.
    The commission, upon notice to the public utility,
    may:
    . . . .
    (2)     After a hearing, by order:

    25
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    clauses––do not require a hearing.12         Thus, not only are
    automatic rate adjustment clauses exempted from HRS § 269–16(b)’s
    hearing requirement, they are also defined by the relevant agency
    rule as provisions that allow for rate changes without a prior
    hearing.
    The PUC approved the Amended PPA pursuant to, in part,
    HAR § 6-60-6 (effective June 19, 1981).           In so doing, it
    authorized HELCO to include energy power purchase costs in its
    Energy Cost Adjustment Clause (ECAC) and to include non-energy
    purchased power costs in its Purchased Power Adjustment Clause
    (PPAC).    According to the 2017 D&O, HELCO’s ECAC and PPAC are
    “fuel adjustment clauses” under HAR § 6-60-6.13            The PUC
    12
    The utility’s rate schedules may include automatic rate
    adjustment clauses, only for those clauses previously
    approved by the commission. Upon effective date of
    this Chapter, any fuel adjustment clause submitted for
    commission approval shall comply with the following
    standards:
    (1)   “Fuel adjustment clause” means a provision of a
    rate schedule which provides for increases or
    decreases or both, without prior hearing, in
    rates reflecting increases or decreases or both
    in costs incurred by an electric or gas utility
    for fuel and purchased energy due to changes in
    the unit cost of fuel and purchased energy.
    (2)   No changes in fuel and purchased energy costs
    may be included in the fuel adjustment clause
    unless the contracts or prices for the purchase
    of such fuel or energy have been previously
    approved or filed with the commission.
    HAR § 6-60-6 (emphases added).
    13
    The Amended PPA defines “Energy Cost Adjustment Clause” as:
    [HELCO]’s cost recovery mechanism for fuel and
    purchased energy costs approved by the PUC in

    26
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    specifically noted that HAR § 6-60-6 “generally governs the
    propriety of fuel adjustment clauses[,]” and stated in its
    Findings and Conclusions that:
    [I]n the Underlying [2012] Decision and Order
    regarding the Original PPA, the commission found it
    “reasonable to authorize recovery of the purchased
    energy charges through [HELCO’s] ECAC, and to recover
    the non-energy purchased power costs (including the
    related revenue taxes) through [HELCO’s] PPAC, to the
    extent that such costs are not included in base
    rates.” Because the energy and capacity payments in
    the [Amended PPA], as in the Original PPA, continue to
    not be included in another cost recovery mechanism,
    and given the above findings concerning pricing under
    the [Amended PPA], the commission authorizes the same
    recovery under the [Amended PPA].
    In MECO, we considered whether a hearing was required
    under HRS § 269–16(b) before the PUC could approve Maui
    Electric’s request to recover costs through its existing ECAC.
    MECO, 141 Hawaii at 
    259-60, 408 P.3d at 11-12
    .               In making our
    determination that a hearing was not required by HRS § 269–16(b),
    we stated the following:
    [T]he Commission authorized Maui Electric to recover
    charges for purchased energy under the Agreement
    through Maui Electric’s existing energy cost
    adjustment clause. There is nothing in the record
    indicating that Maui Electric’s energy cost adjustment
    clause was not previously approved by the Commission
    13
    (...continued)
    conformance with [HAR] § 6-60-6 whereby the base
    electric energy rates charged to retail customers are
    adjusted to account for fluctuations in the costs of
    fuel and purchased energy or such successor provision
    that may be established from time to time.
    “Purchased Power Adjustment Clause” is defined as “[t]he Purchased
    Power Adjustment Clause approved by the PUC in Decision and Order
    No. 30168 in Docket No. 2009-0164 on February 8, 2012.”
    27
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    or that the Commission’s decision revised the existing
    adjustment clause. Additionally, the record does not
    suggest that the use of the fuel adjustment clause in
    this case would cover anything other than increases or
    decreases in the unit cost of purchased energy
    determined by the last rate case proceeding for the
    utility. See HAR § 6–60–6(3).
    
    Id. Similarly here,
    the PUC authorized HELCO to recover
    charges for purchased power through its existing ECAC and PPAC.
    The record indicates that these adjustment clauses were
    previously approved and were not revised by the PUC’s 2017 D&O.
    Furthermore, the record does not suggest that the adjustment
    clauses would cover anything other than changes in the unit cost
    of purchased power determined by the last rate case proceeding.
    Accordingly, because the rate adjustments implicated by
    the Amended PPA were established pursuant to automatic adjustment
    clauses previously approved by the PUC, the PUC was not required
    to hold a contested case hearing under HRS § 269-16(b) prior to
    approving the Amended PPA.
    (B)   HRS § 269-27.2(d)
    Pursuant to HRS § 269–27.2(d), the PUC may only allow a
    public utility to impose an interim increase in rates to recover
    payments made to “nonfossil fuel producers for firm capacity and
    related revenue taxes” after an evidentiary hearing.14               As
    14
    HRS § 269–27.2(d) provides, in pertinent part:
    Upon application of a public utility that supplies
    electricity to the public, and notification of its
    customers, the commission, after an evidentiary
    (continued...)
    28
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    discussed above, in approving the Amended PPA, the PUC authorized
    HELCO to include energy power purchase costs and non-energy
    purchased power costs in its ECAC and PPAC, respectively, to the
    extent that such costs were not included in its base rates.
    However, HELCO’s ECAC and PPAC are fuel adjustment clauses
    specifically exempt from hearing requirements and do not
    constitute an “interim increase in rates” for the purposes of HRS
    § 269-27.2(d).
    In MECO, we similarly considered whether a hearing was
    required under HRS § 269–27.2(d).             MECO, 141 Hawaii at 
    259, 408 P.3d at 11
    .        In determining that a hearing was not required by
    HRS § 269–27.2(d), we stated that:
    Sierra Club has not argued that the [PUC]’s decision
    authorized Maui Electric to impose an interim increase
    in rates for the purpose of recovering payments for
    firm capacity, nor has Sierra Club argued that Maui
    Electric ever sought permission to do so. Indeed, the
    record indicates that one of the features of the
    Agreement was to eliminate the capacity payments that
    Maui Electric was paying to HC & S under the existing
    agreement. Accordingly, the requirement of a hearing
    provided for in HRS § 269-27[.2](d) is not applicable
    to the Application in this case.
    
    Id. As in
    MECO, LOL does not argue that the PUC authorized
    an interim increase in HELCO’s base rates when it approved the
    14
    (...continued)
    hearing, may allow payments made by the public utility
    to nonfossil fuel producers for firm capacity and
    related revenue taxes to be recovered by the public
    utility through an interim increase in rates[.]
    (Emphases added).
    29
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    Amended PPA, or that HELCO sought permission to impose such an
    increase.     As such, the PUC was not required to hold a contested
    case hearing under HRS § 269-27.2(d) prior to approving the
    Amended PPA.
    (C)   Constitutional Due Process
    LOL argues that a contested case hearing was required
    by constitutional due process prior to the PUC’s approval of the
    Amended PPA.     As set forth below, we agree.
    This court engages in a two-step inquiry when
    evaluating claims of a due process right to a hearing:                “(1) is
    the particular interest which [the] claimant seeks to protect by
    a hearing ‘property’ within the meaning of the due process
    clauses of the federal and state constitutions, and (2) if the
    interest is ‘property,’ what specific procedures are required to
    protect it.”     Sandy Beach Def. Fund v. City Council of Honolulu,
    
    70 Haw. 361
    , 376, 
    773 P.2d 250
    , 260 (1989) (citing Aguiar v. Haw.
    Hous. Auth., 
    55 Haw. 478
    , 495, 
    522 P.2d 1255
    , 1266 (1974)).
    Accordingly, to determine whether LOL was entitled to a
    contested case hearing pursuant to constitutional due process, we
    must first determine whether LOL possesses “an interest which
    qualifies as ‘property’ within the meaning of the constitution.”
    
    Id. If LOL
    does possess such a property interest, we must then
    consider whether a contested case hearing was required to protect
    that interest.      
    Id. 30 ***
    FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    (1)   Constitutionally Cognizable
    Property Interest
    “[A] protected property interest exists in a benefit —
    tangible or otherwise — to which a party has a legitimate claim
    of entitlement.”     MECO, 141 Hawaii at 
    260, 408 P.3d at 12
    (internal quotation marks omitted) (citing Sandy Beach Def. 
    Fund, 70 Haw. at 377
    , 773 P.2d at 260).         This court has explained that:
    The legitimate claims of entitlement that constitute
    property interests are not created by the due process
    clause itself. Instead, “they are created and their
    dimensions are defined by existing rules or
    understanding that stem from an independent source
    such as state law — rules or understanding that secure
    certain benefits and that support claims of
    entitlement to those benefits.”
    
    Id. (quoting In
    re Īao Ground Water Mgmt. Area High-Level Source
    Water Use Permit Applications, 128 Hawaii 228, 241, 
    287 P.3d 129
    , 142 (2012)).
    LOL argues that it was entitled to due process to
    protect its constitutional right to a clean and healthful
    environment provided by article XI, section 9 of the Hawaii
    Constitution and HRS Chapter 269.         Article XI, section 9
    provides:
    Each person has the right to a clean and healthful
    environment, as defined by laws relating to
    environmental quality, including control of pollution
    and conservation, protection and enhancement of
    natural resources. Any person may enforce this right
    against any party, public or private, through
    appropriate legal proceedings, subject to reasonable
    limitations and regulation as provided by law.
    In MECO, this court similarly considered whether the
    31
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    PUC violated Sierra Club’s due process rights by approving a
    power purchase agreement between a utility company and a producer
    of electricity without holding a contested case hearing to
    consider the environmental impacts of approving the agreement.
    
    Id. at 260-65,
    408 P.3d at 12-17.            This court recognized that
    Sierra Club’s interest in its right to a clean and healthful
    environment, as defined by laws relating to environmental
    quality, is a property interest protected by due process, as it
    is a substantive right guaranteed by the Hawaii Constitution.
    
    Id. at 260-61,
    408 P.3d at 12-13.
    This court then determined that “HRS Chapter 269 is a
    law relating to environmental quality that defines the right to a
    clean and healthful environment under article XI, section 9 by
    providing that express consideration be given to reduction of
    [GHG] emissions in the decision-making of the Commission.”                  
    Id. at 264,
    408 P.3d at 16.         This court held that Sierra Club’s
    assertion of a right to a clean and healthful environment, as
    defined by HRS Chapter 269, therefore established a protectable
    property interest under article XI, section 9 and HRS Chapter
    269.    
    Id. Like the
    appellant in MECO, LOL seeks to protect its
    property interest in a clean and healthful environment, as
    defined by HRS Chapter 269.          LOL stated in the 2017 Docket that:
    Life of the Land is a non-profit Hawaii-based
    organization. Our members are very deeply concerned
    about climate change, biodiversity, and the spread of
    32
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    invasive species. Life of the Land believes that the
    efforts to protect our archipelago from the ravages of
    climate change, and the introduction of alien species
    has not been adequately protected and funded by
    legislative actions.
    LOL asserts that “its members are located in Hawaii
    and are directly concerned with preventing climate change
    impacts, biodiversity, and the spread of invasive species, all of
    which are affected by GHG emissions, as well as other
    environmental and public interest impacts of [the] PUC’s
    decisionmaking on the [Amended PPA].”            Consequently, pursuant to
    article XI, section 9 of the Hawaii Constitution and HRS Chapter
    269, as interpreted by this court in MECO, LOL has shown a
    constitutionally cognizable property interest in this case.
    (2)   A Contested Case Hearing was
    Required
    Having determined that LOL has demonstrated a protected
    property interest in a clean and healthful environment as defined
    by HRS Chapter 269, “we next consider what procedures due process
    requires in this case.”        MECO, 141 Hawaii at 
    265, 408 P.3d at 17
    .   When determining the procedures required to comply with
    constitutional due process, we consider the following three
    factors:    “(1) the private interest which will be affected; (2)
    the risk of an erroneous deprivation of such interest through the
    procedures actually used, and the probable value, if any, of
    additional or alternative procedural safeguards; and (3) the
    governmental interest, including the burden that additional
    33
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    procedural safeguards would entail.”         Sandy Beach Def. 
    Fund, 70 Haw. at 378
    , 773 P.2d at 261 (citations omitted).             Upon
    consideration of each of these factors, we conclude that a
    contested case hearing was required.
    First, the private interest to be affected is LOL’s
    right to a clean and healthful environment, which “includes the
    right that explicit consideration be given to reduction of [GHG]
    emissions in Commission decision-making, as provided for in HRS
    Chapter 269.”    MECO, 141 Hawaii at 
    265, 408 P.3d at 17
    .            The
    Amended PPA involves the construction and operation of a biomass
    combustion facility by Hu Honua, and reliance on the facility by
    HELCO for an extended term of thirty years.           As in MECO, as part
    of the 2017 Docket, the PUC was asked to consider the
    reasonableness of the energy charges implicated by the Amended
    PPA, and to determine whether the arrangement was prudent and in
    the public interest.     This “would necessarily include an
    evaluation of the hidden and long-term costs of the activities”
    of the Hu Honua facility.       
    Id. at 266,
    408 P.3d at 18.          Because
    the PUC’s determinations of these issues would require
    consideration of the level of GHG emissions generated by the Hu
    Honua facility, LOL’s right to a clean and healthful environment,
    as defined by HRS Chapter 269, was directly affected by the PUC’s
    approval of the Amended PPA under MECO.
    Further, the PUC’s 2017 D&O concluded that the Amended
    PPA was “consistent with HRS chapter 269” and was approved based
    34
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    in part on “the State’s need to limit its dependence on fossil
    fuels and mitigate against volatility in oil pricing.”              The PUC’s
    decision thus implicated LOL’s constitutional right to a clean
    and healthful environment, as defined by HRS Chapter 269.
    Accordingly, the PUC’s approval of the Amended PPA under the
    terms of the 2017 D&O adversely affected LOL’s private interest.
    Second, the risk of erroneous deprivation is high in
    this case, absent the protections provided by a contested case
    hearing.   Consistent with public comments in opposition to the
    project, LOL posits that the PUC’s approval of the Amended PPA
    could have adverse environmental impacts.           Yet, the restricted
    scope of the 2017 Docket prevented LOL from addressing these
    potential impacts.     See MECO, 141 Hawaii at 
    266, 408 P.3d at 18
    (risk of erroneous deprivation of Sierra Club’s interest was high
    due to potential impact on air quality and absence of
    opportunities to be heard concerning electricity producer’s
    performance under the agreement).
    Finally, regarding the governmental interest, the
    burden of affording LOL a contested case hearing is slight
    because the PUC is already statutorily required to consider the
    long-term effects of its decisions.         See 
    id. (affording Sierra
    Club a hearing would not unduly burden the PUC in light of its
    statutory duty to consider the long-term effects of its
    decisions).
    Accordingly, and consistent with this court’s
    35
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    conclusion in MECO, a hearing conducted by the PUC was required
    by constitutional due process to protect LOL’s right to a clean
    and healthful environment, as defined by HRS Chapter 269.               
    Id. at 269,
    408 P.3d at 21.
    ii.    “Rights, Duties, and Privileges”
    A contested case hearing is one that is (1) required by
    law and (2) determines the rights, duties, and privileges of
    specific parties.      MECO, 141 Hawaii at 
    258, 408 P.3d at 10
    (citing Kilakila, 131 Hawaii at 
    200, 317 P.3d at 34
    ) (internal
    quotation marks omitted).       Having determined that a contested
    case hearing was required by constitutional due process, the
    question becomes whether the 2017 Docket, in which the PUC
    approved the Amended PPA, constituted a contested case hearing.
    We conclude that the 2017 Docket was a contested case hearing
    because the hearing required by law would have determined HELCO’s
    rights, duties, and privileges.
    This court has explained that:
    HRS § 91–1 [Supp. 2018] does not contain the
    requirement that the hearing be a “trial-type
    evidentiary hearing” or that the hearing exhibit a
    particular level of “adversarial” quality. Rather,
    . . . there are only two requirements for a hearing to
    be regarded as a contested case hearing: (1) that the
    hearing be required by law and (2) that the hearing
    determine the rights, duties, or privileges of
    specific parties.
    E & J Lounge Operating Co. v. Liquor Comm’n of City & Cty. of
    Honolulu, 118 Hawaii 320, 333, 
    189 P.3d 432
    , 445 (2008).
    In Kilakila, the Board of Land and Natural Resources
    36
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    (BLNR) approved an application submitted by the University of
    Hawaii (UH) to permit construction of astronomy facilities near
    the summit of Haleakalā on Maui.          131 Hawaii 193, 
    317 P.3d 27
    .
    The circuit court dismissed an appeal of the BLNR’s decision for
    lack of jurisdiction under HRS § 91-14 because no formal
    contested case hearing had been held.          The ICA affirmed.       
    Id. at 196,
    317 P.3d at 30.     This court determined that, although no
    formal contested case hearing occurred, the BLNR proceedings that
    resulted in the granting of UH’s application constituted a
    contested case hearing.      
    Id. at 200-02,
    317 P.3d at 34-36.
    We first determined that UH’s application “necessitated
    a hearing by law - i.e., by the administrative rules governing
    [Department of Land and Natural Resources] and BLNR.”               
    Id. at 202,
    317 P.3d at 36.     We then stated the following regarding the
    “rights, duties, and privileges” requirement of a contested case
    hearing:
    In this case, no formal contested case hearing was
    actually held before the BLNR voted to grant the
    permit in this case, so the question becomes whether a
    formal hearing would have determined — or whether the
    proceedings that did take place determined — the
    “rights, duties, and privileges of specific parties.”
    The inquiry here is “directed at the party whose
    application was under consideration.” Thus, we focus
    on the rights, duties, and privileges of UH.
    . . . . UH’s proposed project involves construction
    of a substantial complex of astronomy facilities on
    conservation district land. . . . UH could not
    legally commence that construction without first
    submitting an application for a permit and having that
    application reviewed and approved by BLNR. Approval,
    including any conditions attached thereto, or denial
    37
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    of the application clearly implicates whether UH would
    or would not be able to engage in the requested use of
    building astronomy facilities at the telescope project
    site. Thus, a formal contested case hearing approving
    o[r] denying UH’s application would have determined
    UH’s rights, duties, or privileges with regard to the
    project. Even in the absence of a formal contested
    case hearing, we point out that the proceedings that
    otherwise took place, including the vote to grant the
    permit, in fact did determine UH’s rights, duties, and
    privileges.
    
    Id. (emphases added)
    (citations omitted).
    Because approval of UH’s permit was required before it
    could construct astronomy facilities at the project site, the
    proceedings that took place determined UH’s rights, duties, and
    privileges.   
    Id. We therefore
    concluded that, although no formal
    contested case hearing was conducted, the BLNR proceedings
    nevertheless constituted a contested case hearing within the
    meaning of HRS § 91-14.      
    Id. Similar to
    the BLNR proceedings at issue in Kilakila,
    no formal contested case hearing was held before the PUC approved
    the Amended PPA in the 2017 D&O.          We must therefore address
    “whether a formal hearing would have determined - or whether the
    proceedings that did take place determined - the ‘rights, duties,
    and privileges’” of HELCO.       Kilakila, 131 Hawaii at 
    202, 317 P.3d at 36
    (noting that the inquiry is “directed at the party
    whose application was under consideration”) (citation and
    quotation marks omitted).
    Pursuant to HRS § 269-27.2(c), HELCO and Hu Honua’s
    Amended PPA would be of no force and effect without approval by
    38
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    the PUC.   Thus, had the PUC held a formal contested case hearing
    to determine whether the Amended PPA should be approved or
    rejected, that hearing would have determined the rights, duties,
    and privileges of HELCO.      Even in the absence of a formal
    contested case hearing, the proceedings that took place in the
    2017 Docket resulted in the PUC’s approval of the Amended PPA,
    and therefore did in fact determine HELCO’s rights, duties, and
    privileges.     Accordingly, the PUC’s proceedings in the 2017
    Docket constituted a contested case hearing within the meaning of
    HRS § 91-14.
    b.     LOL Followed Agency Rules and Was Involved in the
    Contested Case
    Judicial review over an agency appeal under HRS § 91-14
    is only available where the claimant “followed the applicable
    agency rules and, therefore, [was] involved in the contested
    case.”   MECO, 141 Hawaii at 
    258, 408 P.3d at 10
    (quoting
    Kilakila, 131 Hawaii at 
    200, 317 P.3d at 34
    ).           Hu Honua, HELCO,
    and the PUC argue that LOL was not entitled to a contested case
    hearing because it failed to request such a hearing.             As set
    forth below, this argument is without merit, as LOL was not
    required to request a contested case hearing.
    i.   A Request for a Contested Case Hearing Was
    Not Required Pursuant to Administrative Rule
    Hu Honua argues that LOL was required to request a
    contested case hearing pursuant to HAR §§ 6-61-74 (effective
    39
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    1992-2018) and 6-61-55.15       However, the PUC’s administrative
    rules do not contain such a requirement.           HAR § 6-61-74 provided
    the substantive requirements for applications and petitions to
    the PUC generally, and HAR § 6-61-55 described the substance of
    an application to intervene as a party in a PUC proceeding.
    Neither of these rules, which remain effective in HAR title 16,
    chapter 601, requires a party to request a contested case
    hearing.   Moreover, no other rule that governs the rules of
    15
    HAR § 6-61-74 provided:
    All applications and petitions shall:
    (1)    State clearly and concisely the authorization or
    relief sought;
    (2)    Cite the appropriate statutory provision or
    other authority under which commission
    authorization or relief is sought; and
    (3)    In addition to specific requirements for
    particular types of applications (see
    subchapters 7 to 10), state the following:
    (A)   The applicant's legal name and location of
    principal place of business, and, if a
    corporation, trust, association, or other
    organization, the state under whose laws
    the applicant was organized;
    (B)   The name, title, and address of the person
    to whom correspondence or communications
    in regard to the application are to be
    addressed. Notices, orders, and other
    documents shall be served upon the person
    named, and that service shall be deemed to
    be service upon the applicant; and
    (C)   If ex parte action or relief pending full
    hearing is sought, the necessity or
    emergency justifying the requested action.
    See infra note 22. HAR § 16-601-74 (effective Jan. 1, 2019)
    provides identical requirements.
    40
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    practice and procedure before the PUC imposes such a requirement.
    Furthermore, it is undisputed that LOL was involved in the PUC’s
    proceeding as a participant.        Accordingly, judicial review over
    LOL’s appeal is not precluded on this basis.
    In contrast, HAR Chapter 13-1, governing the rules of
    practice and procedure before the Department of Land and Natural
    Resources, contains a requirement that a claimant “request a
    contested case and petition the board to hold a contested case
    hearing.”    HAR § 13-1-29(a) (effective Feb. 27, 2009).16            This
    court has recognized that “HAR § 13–1–29 is the applicable agency
    rule delineating the specific procedures for requesting a
    contested case hearing.”17       Hui Kakoo Aina Hoopulapula v. Bd. of
    16
    HAR § 13-1-29(a) provides:
    On its own motion, the board may hold a contested case
    hearing. Others must both request a contested case
    and petition the board to hold a contested case
    hearing. An oral or written request for a contested
    case hearing must be made to the board no later than
    the close of the board meeting at which the subject
    matter of the request is scheduled for board
    disposition. An agency or person so requesting a
    contested case must also file (or mail a postmarked)
    written petition with the board for a contested case
    no later than ten calendar days after the close of the
    board meeting at which the matter was scheduled for
    disposition. For good cause, the time for making the
    oral or written request or submitting a written
    petition or both may be waived.
    (Emphasis added).

    HAR § 13-1-29 has been amended slightly since this court decided
    Hui Kakoo Aina Hoopulapula. When the case was decided, HAR § 13-1-29(a)
    stated:
    A hearing on a contested matter may be requested by
    the board on its own motion or upon the written

    143 P.3d 1230
    , 1242 (2006),
    abrogated on other grounds by Tax Found. of Hawaii v. State,
    SCAP-16-462, 
    2019 WL 1292286
    (Haw. Mar. 21, 2019).                We noted that
    the appellants had made oral requests for a contested case
    hearing prior to the close of a BLNR meeting, but had failed to
    subsequently submit a written petition to the BLNR requesting a
    contested case hearing.          
    Id. We thus
    determined that “inasmuch
    as the DLNR had properly promulgated specific procedures for a
    contested case hearing . . . and the Appellants failed to follow
    the requisite procedures, there was no contested case from which
    the Appellants could appeal, pursuant to HRS § 91-14(a).”                   
    Id. at 41,
    143 P.3d at 1243.
    In contrast, the PUC’s administrative rules do not
    require claimants to request a contested case hearing.                   Thus, LOL
    did not fail to adhere to the applicable agency rules in seeking
    judicial review of its agency appeal without requesting a
    17
    (...continued)
    petition of any government agency or any interested
    person who then properly qualifies to be admitted as a
    party. An oral or written request for a contested
    case hearing must be made by the close of the public
    hearing (if one is required) or the board meeting at
    which the matter is scheduled for disposition (if no
    public hearing is required). In either situation, the
    person or agency requesting the contested case hearing
    must file (or mail and postmark) a written petition
    with the board not later than ten days after the close
    of the public hearing or the board meeting, whichever
    is applicable. The time for making an oral or written
    request and submitting a written petition may be
    waived by the board.

    contested case hearing.
    ii.    A Request for a Contested Case Hearing Was
    Not Required by Hawaii Case Law
    The PUC argues that “[t]his court’s case law on
    contested case hearings clearly indicates that a request for a
    contested case hearing is a necessary prerequisite to judicial
    review of the kind LOL seeks.”        The PUC cites MECO, 141 Hawaii
    at 
    255, 408 P.3d at 7
    , Mauna Kea Anaina Hou v. Bd. of Land & Nat.
    Res., 136 Hawaii 376, 380, 
    363 P.3d 224
    , 228 (2015), Kilakila,
    131 Hawaii at 195, 
    204, 317 P.3d at 29
    , 38, Kaleikini v.
    Thielen, 124 Hawaii 1, 4, 
    237 P.3d 1067
    , 1070 (2010), and Pele
    Defense Fund, 77 Hawaii at 
    66, 881 P.2d at 1212
    , for the
    proposition that “at the very least, a party must have requested
    a contested case hearing before it can object to the denial of
    such a hearing.”    To the contrary, this court’s case law does not
    require a party to request a hearing to gain access to the
    courts, where the relevant agency has not promulgated a rule
    requiring such a request and the party has participated in a
    contested case proceeding.
    A formal request for a contested case hearing is not a
    prerequisite for judicial review over an appeal under the cases
    cited by the PUC.      In MECO, this court noted that, although the
    Sierra Club was not allowed to participate in the PUC’s
    proceeding, it formally requested a contested case hearing.
    MECO, 141 Hawaii at 
    255-57, 408 P.3d at 7-8
    .           This court did
    43
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    not, however, hold that a formal request for a contested case
    hearing is a prerequisite for judicial review.             Furthermore,
    MECO is distinguishable from the instant case because unlike the
    Sierra Club in MECO, LOL actively participated in the 2017
    Docket.    Mauna Kea Anaina Hou, Kilakila, and Kaleikini are also
    distinguishable because each of those cases concerned appeals of
    BLNR decisions, and as 
    explained supra
    , agency rules of the BLNR,
    unlike those of the PUC, require that a formal request for a
    contested case hearing be submitted to attain judicial review
    over an agency appeal.
    Pele Defense Fund, which involved an appeal of a
    Department of Health (DOH) decision, is similarly distinguishable
    because DOH rules provide that in order to obtain judicial
    review, an interested person seeking a contested case hearing
    must submit a complaint or application requesting such a
    hearing.18    77 Hawaii at 
    69, 881 P.2d at 1215
    (“Appellees
    submitted ‘Application[s] for Contested Case[s]’ on forms
    provided by the DOH and in full compliance with the agency’s
    rules.”).     Accordingly, the cases cited by the PUC do not
    establish that LOL was required to request a contested case
    hearing as a prerequisite to judicial review.
    18
    DOH rules also allow the DOH to hold a contested case hearing on
    its own motion. See Pele Defense Fund, 77 Hawaii at 69 n.12, 
    881 P.2d 1215
    n.12.

    B.   Standing
    In the context of administrative appeals brought
    pursuant to HRS § 91-14(a), this court has interpreted the
    concept of standing to be comprised of two components.19              Jordan
    v. Hamada, 
    64 Haw. 451
    , 457-58, 
    643 P.2d 73
    , 75-76 (1982).
    “First, one must be a person aggrieved, inter alia, by a final
    decision and order in a contested case.           Second, the aggrieved
    person must have participated in the contested case from which
    the decision affecting him resulted.”           
    Id. (citation and
    internal
    quotation marks omitted); see also Mahuiki v. Planning Comm’n, 
    65 Haw. 506
    , 515, 
    654 P.2d 874
    , 880 (1982).
    1.    “Person Aggrieved”
    To be a person aggrieved, “one must be specially,
    personally, and adversely affected” by the final decision and
    order at issue.       Life of the Land, Inc. v. Land Use Comm’n, 
    61 Haw. 3
    , 7, 
    594 P.2d 1079
    , 1082 (1979) (quoting East Diamond Head
    Ass’n v. Zoning Board of Appeals, 
    52 Haw. 518
    , 523 n.5, 
    479 P.2d 796
    , 799 n.5 (1971)).       An unfavorable final decision and order is
    not enough to satisfy this prong of the analysis - “[t]here must
    be a special injury or damage to one’s personal or property
    rights[,] as distinguished from the role of being only a champion
    of causes.”     
    Id. 19 HRS
    § 91-14(a) provides, in pertinent part, “[a]ny person
    aggrieved by a final decision and order in a contested case . . . is entitled
    to judicial review thereof under this chapter[.]” Pursuant to HRS § 91-1, the
    term “persons” includes individuals, associations, and public or private
    organizations.
    45
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    We have previously recognized the right to a clean and
    healthful environment, as defined by HRS Chapter 269, as a
    “legally protected interest” adequate to confer standing.               MECO,
    141 Hawaii at 
    270-71, 408 P.3d at 22-23
    ; see also Life of the
    Land v. Land Use Comm’n, 
    63 Haw. 166
    , 176-77, 177 n.10, 
    623 P.2d 431
    , 441, 441 n.10 (1981).
    There is sufficient evidence in the record to
    demonstrate that the PUC’s approval of the Amended PPA specially,
    personally, and adversely affected LOL’s members.             As set forth
    above, LOL is a Hawaii-based nonprofit organization comprised of
    members who live, work, and recreate in Hawaii.            Such activity
    includes visiting and exploring the Big Island’s Hāmākua Coast,
    where the Hu Honua facility is located.          LOL asserts that the Hu
    Honua facility’s use of biofuels for energy production may cause
    adverse environmental impacts on the Big Island.            In addition to
    submitting several IRs regarding the GHG emissions associated
    with the Amended PPA, LOL submitted an IR to Hu Honua regarding
    the potential for ocean contamination caused by the improper
    disposal of wastewater at the facility.          It also expressed
    concern regarding the environmental impacts associated with
    “acquiring bioenergy crops” from an area of the Big Island that
    already serves as a source for another biofuel facility, and
    whether the Hu Honua facility will “cut into the utilities[’]
    purchase of energy from existing and/or planned wind and solar
    46
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    farms.”20   These impacts could affect the Big Island in general,
    and the Hāmākua Coast in particular.
    Thus, LOL has demonstrated an injury to its members,
    including their right to a clean and healthful environment as
    defined by HRS Chapter 269, due to the PUC’s approval of the
    Amended PPA.      LOL has therefore satisfied the first prong of the
    standing analysis.      See MECO, 141 Hawaii at 
    270-71, 408 P.3d at 22-23
    ; see also Sierra Club v. Hawaii Tourism Authority ex rel.
    Bd. of Directors, 100 Hawaii 242, 271, 
    59 P.3d 877
    , 906 (2002)
    (“An organization may sue on behalf of its members even though it
    20
    The PUC impliedly recognized this potential injury when it
    determined that, inter alia, “LOL’s concerns regarding the proposed project’s
    impact on existing renewable projects on the Big Island” were sufficient to
    satisfy the requirements of HAR § 6-61-56.
    The grounds for participation without intervention in PUC proceedings, as set
    forth by HAR § 6-61-56(c) were:
    (1)   . . . [T]he direct and substantial interest of
    the applicant;
    (2)   The applicant’s position regarding the matter in
    controversy;
    (3)   The extent to which the participation will not
    broaden the issues or delay the proceeding;
    (4)   The extent to which the applicant’s interest
    will not be represented by existing parties;
    (5)   A statement of the expertise, knowledge or
    experience the applicant possesses with regard
    to the matter in controversy;
    (6)   Whether the applicant can aid the commission by
    submitting an affirmative case; and
    (7)   . . . [T]he relief desired.
    (Emphases added). HAR § 16-601-56(c) sets forth identical grounds for
    participation without intervention.
    47
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    has not been injured itself when:          (1) its members would
    otherwise have standing to sue in their own right; (2) the
    interests the organization seeks to protect are germane to the
    organization's purpose; and (3) neither the claim asserted nor
    the relief itself requested requires the participation of
    individual members in the lawsuit”).
    2.    Participation
    Although an aggrieved person must have participated in
    a contested case in order to invoke judicial intervention, we
    have not “conditioned standing to appeal from an administrative
    decision upon formal intervention in the agency proceeding.”
    
    Mahuiki, 65 Haw. at 515
    , 654 P.2d at 880 (quoting 
    Jordan, 62 Haw. at 449
    , 616 P.2d at 1371).        Where “the appellants have been
    aggrieved by the action of the PUC, and where they were involved
    as participants during the [contested case,] the appellants may
    challenge the order of the PUC in this court.”             Life of the Land,
    Inc. v. Land Use 
    Comm’n, 61 Haw. at 9
    , 594 P.2d at 1083 (internal
    quotation marks and ellipsis omitted) (quoting In Re Application
    of Hawaiian Electric Co., 
    56 Haw. 260
    , 265, 
    535 P.2d 1102
    , 1106
    (1975)).   Because LOL was involved in the 2017 Docket as a
    participant, it has met the second prong of the analysis.                LOL
    therefore has standing under HRS § 91-14(a) to appeal the PUC’s
    2017 D&O and the denial of its Motion to Upgrade Status.
    C.   Merits of LOL’s Appeal
    Pursuant to HRS § 269-6(b), the PUC must explicitly
    48
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    consider the effect of the State’s reliance on fossil fuels on,
    inter alia, GHG emissions.       We have characterized this as a
    “requirement to reduce reliance on fossil fuels and to consider
    [GHG] emissions[, which] applies to the fulfillment of all of the
    [PUC’s] duties.”    MECO, 141 Hawaii at 
    263, 408 P.3d at 15
    .            That
    the facility involved in the Amended PPA is a biofuel facility
    does not absolve the PUC of this duty.          Thus, in approving the
    Amended PPA, the PUC was required to expressly consider the
    reduction of GHG emissions.       
    Id. at 264,
    408 P.3d at 16.
    Further, LOL was entitled to a meaningful opportunity to be heard
    on the issue of the Amended PPA’s impact on its constitutional
    right to a clean and healthful environment, as defined by HRS
    Chapter 269.
    The findings and conclusions in the PUC’s 2017 D&O do
    not show that the PUC expressly considered the reduction of GHG
    emissions in reaching its decision.         The PUC also denied LOL due
    process by preventing LOL from addressing the impacts of
    approving the Amended PPA on LOL’s right to a clean and healthful
    environment, as defined by HRS Chapter 269.
    1.   The PUC Failed to Satisfy its Statutory Obligations
    Under HRS § 269-6(b)
    HRS § 269-6(b) provides:
    The public utilities commission shall consider the
    need to reduce the State’s reliance on fossil fuels
    through energy efficiency and increased renewable
    energy generation in exercising its authority and
    duties under this chapter. In making determinations
    of the reasonableness of the costs of utility system
    49
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    capital improvements and operations, the commission
    shall explicitly consider, quantitatively or
    qualitatively, the effect of the State’s reliance on
    fossil fuels on price volatility, export of funds for
    fuel imports, fuel supply reliability risk, and [GHG]
    emissions. The commission may determine that
    short-term costs or direct costs that are higher than
    alternatives relying more heavily on fossil fuels are
    reasonable, considering the impacts resulting from the
    use of fossil fuels.
    (Emphases added).
    In MECO, this court observed that “[i]n 2011, the
    legislature amended HRS § 269-6(b) to make it mandatory for the
    Commission when exercising its duties to recognize the ‘need’ to
    reduce reliance on fossil fuels and to ‘explicitly consider’ the
    levels and effect of [GHG] emissions[.]”           141 Hawaii at 
    262, 408 P.3d at 14
    (emphasis in original).          This court determined that “a
    primary purpose of the [2011 amendment] was to require the
    Commission to consider the hidden and long-term costs of reliance
    on fossil fuels, which subjects the State and its residents to
    increased air pollution and potentially harmful climate change
    due to the release of harmful [GHGs].”21          
    Id. at 263,
    408 P.3d at
    21
    Relatedly, we note that the State has committed to furthering the
    goals of the Paris Climate Agreement. 2018 Haw. Sess. Laws. Act 15, § 1 at
    46-47 (“The legislature notes that Hawaii, as part of the United States
    Climate Alliance . . . committed to upholding the objectives of the 2015 Paris
    Agreement.”). This commitment is advanced through HRS Chapter 225P, which
    provides, in part:
    The purpose of [the] chapter is to address the effects
    of climate change to protect the State’s economy,
    environment, health, and way of life. [The] chapter
    establishes the framework for the State to:
    1)    Adapt to the inevitable impacts of global
    warming and climate change, including rising sea

    15 (quoting H. Stand. Comm. Rep. No. 1004, in 2011 House Journal,
    at 1332) (internal quotation marks omitted).               This court then
    concluded that “HRS § 269-6(b)’s requirement to reduce reliance
    on fossil fuels and to consider [GHG] emissions applies to the
    fulfillment of all of the Commission’s duties.”               
    Id. (emphasis added).
          Accordingly, pursuant to MECO, HRS § 269-6(b) requires
    that “express consideration be given to reduction of [GHG]
    emissions in the decision-making of the Commission.”                  
    Id. at 264,
    408 P.3d at 16.         Thus, it is clear that the PUC was required to
    expressly consider the reduction of GHG emissions in deciding
    whether to approve the Amended PPA.
    In determining whether the PUC satisfied this duty
    pursuant to HRS § 269-6(b), this court “should ensure that the
    agency . . . [made] its findings reasonably clear.                The parties
    and the court should not be left to guess . . . the precise
    finding of the agency.”          Kauai Springs, Inc. v. Planning Comm’n
    of Cty. of Kauai, 133 Hawaii 141, 164, 
    324 P.3d 951
    , 974 (2014)
    (citation and quotation marks omitted).              “An agency’s findings
    should be sufficient to allow the reviewing court to track the
    21
    (...continued)
    levels, temperatures, and other risk factors;
    and
    2)    Mitigate its greenhouse gas emissions by
    sequestering more atmospheric carbon and
    greenhouse gases than the State produces as
    quickly as practicable, but no later than 2045.
    HRS § 225P-1 (Supp. 2018).

    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    steps by which the agency reached its decision.”            
    Id. (citation and
    quotation marks omitted); see also In re Waiola O Molokai,
    Inc., 103 Hawaii 401, 432, 
    83 P.3d 664
    , 695 (2004) (explaining
    that any presumption of validity, given to an agency’s decision,
    “presupposes that the agency has grounded its decision in
    reasonably clear” findings of fact and conclusions of law).
    Because the 2017 D&O does not reflect that the PUC
    explicitly considered the reduction of GHG emissions in approving
    the Amended PPA, we conclude that the PUC failed to comply with
    HRS § 269-6(b).    The only reference to GHG emissions in the 2017
    D&O appears in the “Procedural Background” section.             It reads,
    “[c]omments in opposition to the Project tended to focus on
    potential adverse environmental impacts, an expected rise in
    [GHG] emissions, . . . and general objections to biomass as a
    fuel resource.”    The 2017 D&O does not provide responses to those
    comments, nor is there any mention of GHG emissions in the PUC’s
    “Statement of Issues” or “Discussion and Findings.”             Further,
    although the PUC restated HELCO’s representations that the
    biomass facility could potentially save approximately 15,700
    barrels of fuel per year and contribute to the State’s RPS goals,
    it made no express findings or conclusions regarding the biomass
    facility’s GHG emissions.
    In its findings and conclusions, the PUC found that Hu
    Honua’s biomass facility may displace fossil fuel generation
    resources and accelerate the retirement of fossil fuel plants,
    52
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    and noted that its decision to approve the Amended PPA was based
    on “factors such as the State’s need to limit its dependence on
    fossil fuels and mitigate against volatility in oil pricing.”
    These findings and conclusions do not constitute “express
    consideration” of the reduction of GHG emissions, as provided for
    under HRS § 269-6(b).        See MECO, 141 Hawaii at 
    264, 408 P.3d at 16
    .
    In MECO, Maui Electric requested that the PUC determine
    whether its proposed PPA was prudent and in the public interest,
    and consider the reasonableness of the associated energy charges.
    
    Id. at 265-66,
    408 P.3d at 17-18.           This court explained that when
    reviewing the PPA, the PUC was required under HRS § 269-6(b) to
    consider the hidden and long-term costs of energy produced under
    the Agreement, including the potential for increased air
    pollution due to GHG emissions.          
    Id. at 266,
    408 P.3d at 18.
    This court further stated that the consideration of potential
    health risks is “axiomatic” in the PUC’s analysis of the level of
    GHG emissions, “as contemplated by the legislature when it
    amended HRS § 269-6(b) in 2011[.]”           
    Id. Similarly, in
    the instant case, HELCO requested that
    the PUC determine whether the energy charges under the Amended
    PPA were reasonable and if its arrangement with Hu Honua was
    prudent and in the public interest.           In its review of the Amended
    PPA, the PUC found that the “purchased power costs and
    arrangements set forth in the [Amended] PPA appear reasonable,
    53
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    prudent, in the public interest, and consistent with HRS chapter
    269 in general, and HRS § 269-27.2(c), in particular.”              The PUC
    did not, however, substantiate this finding by addressing the
    hidden and long-term environmental and public health costs of
    reliance on energy produced at the proposed facility, as
    required.    These costs include “the potential for increased air
    pollution as a result of GHG emissions” directly attributed to
    energy generation at the facility, as well as GHG emissions
    produced at earlier stages in the production process, such as

    2.   The PUC’s Failure to Provide LOL an Opportunity to Be
    Meaningfully Heard in the 2017 Docket Denied LOL Due
    Process
    “The basic elements of procedural due process of law
    require notice and an opportunity to be heard at a meaningful
    time and in a meaningful manner before governmental deprivation
    of a significant property interest.”         Sandy Beach Def. 
    Fund, 70 Haw. at 378
    , 773 P.2d at 261 (citing Matthews v. Eldridge, 
    424 U.S. 319
    , 333 (1976)).      As 
    discussed supra
    , this court has
    recognized that the “right to a clean and healthful environment,
    as defined by laws relating to environmental quality,” is a
    property interest protected by due process because it is a
    substantive right guaranteed by article XI, section 9 of the
    Hawaii Constitution.     MECO, 141 Hawaii at 253, 
    260-61, 408 P.3d at 5
    , 12-13.     In MECO, after concluding that Sierra Club’s
    asserted property interest required a hearing by the PUC to
    comply with due process, this court observed that procedural due
    process includes “the right to submit evidence and argument on
    . . . the impact of the Agreement on the asserted property
    interest.”     
    Id. at 269,
    408 P.3d at 21 (citation omitted).            This
    court then stated that the PUC “has the authority to set
    limitations in conducting the proceedings so long as the
    56
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    procedures sufficiently afford an opportunity to be heard at a
    meaningful time and in a meaningful manner on the issue of the
    Agreement’s impact on the asserted property interest.”              
    Id. at 270,
    408 P.3d at 22.
    As explained above, procedural due process necessitated
    a contested case hearing because the 2017 D&O, which approved the
    Amended PPA, adversely affected LOL’s constitutionally protected
    right to a clean and healthful environment, as defined by HRS
    Chapter 269.   See id. at 
    265, 408 P.3d at 17
    (agency hearing
    required “when the challenged State action adversely affects the
    constitutionally protected rights of others”) (quoting Pele Def.
    Fund, 77 Hawaii at 
    68, 881 P.2d at 1214
    ) (internal quotation
    marks omitted).    Accordingly, LOL was entitled to an opportunity
    to be heard at a meaningful time and in a meaningful manner
    regarding the Amended PPA’s impact on its right to a clean and
    healthful environment, as defined by HRS Chapter 269.              See id. at
    
    270, 408 P.3d at 22
    .
    LOL was not afforded a sufficient opportunity to
    address the Amended PPA’s impact on its constitutional right to a
    clean and healthful environment, as defined by HRS Chapter 269,
    throughout the 2017 Docket.       The PUC allowed LOL to participate
    in the 2017 Docket with respect to two sub-issues: (2.a.i)
    whether the energy price components in the Amended PPA properly
    reflect the cost of biomass fuel supply, and (2.b) whether
    HELCO’s purchase power arrangements under the Amended PPA are
    57
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    prudent and in the public interest.         LOL argued that the proposed
    biomass facility was not in the public interest and should be
    rejected.    LOL further argued that “the issue of climate change
    is embedded in both issues the Commission assigned to LOL to
    consider[,]” that Hu Honua’s proposal failed to fully address the
    environmental impact of its operations, and that Hu Honua’s
    claims of carbon-neutrality were unsupported.
    However, HELCO refused to respond to LOL’s IRs
    regarding environmental impacts of the project and production of
    an environmental site assessment because those topics were
    outside the scope of LOL’s participation.           Hu Honua similarly
    objected to LOL’s IRs regarding loss of stored carbon from tree
    harvesting, environmental impacts of the project, and production
    of an environmental site assessment as outside the scope of LOL’s
    restricted participation.       LOL filed a Motion to Compel, seeking
    lease agreements and a forestry operations report from Hu Honua,
    in order to address the cost of biomass fuel supply and GHG
    emissions from the facility’s operations.           However, the PUC
    denied LOL’s motion, finding that “LOL’s Motion to Compel, if
    granted, would cause an undue delay in this proceeding.”
    Thus, although the 2017 D&O acknowledged LOL’s attempts
    to discuss the Amended PPA’s impacts on LOL’s right to a clean
    and healthful environment, as defined by HRS Chapter 269, in
    addressing whether the Amended PPA is prudent and in the public
    interest, the PUC did not afford LOL an opportunity to be heard
    58
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    regarding this issue at a meaningful time and in a meaningful
    manner.   Rather, the PUC prevented LOL from meaningfully
    addressing the impact that approving the Amended PPA would have
    on LOL’s asserted property interest, based on its determination
    that LOL’s environmental concerns were beyond the scope of the
    2017 Docket.   Accordingly, the PUC’s procedures violated LOL’s
    due process right to be meaningfully heard regarding the impacts
    that approving the Amended PPA would have on LOL’s right to a
    clean and healthful environment, as defined by HRS Chapter 269.
    Due to the PUC’s failure to allow LOL to present
    evidence and argument concerning its right to a clean and
    healthful environment, as defined by HRS Chapter 269, this court
    must vacate the PUC’s 2017 D&O and remand this case to the PUC
    for a hearing that complies with procedural due process.              In
    order to comply with statutory and constitutional requirements,
    the PUC’s post-remand hearing must afford LOL an opportunity to
    meaningfully address the impacts of approving the Amended PPA on
    LOL’s members’ right to a clean and healthful environment, as
    defined by HRS Chapter 269.       The hearing must also include
    express consideration of GHG emissions that would result from
    approving the Amended PPA, whether the cost of energy under the
    Amended PPA is reasonable in light of the potential for GHG
    emissions, and whether the terms of the Amended PPA are prudent
    and in the public interest, in light of its potential hidden and
    long-term consequences.      See MECO, 141 Hawaii at 269, 
    408 P.3d 59

    3.   The PUC’s Denial of LOL’s Motion to Upgrade Status
    LOL asserts that the PUC’s denial of its Motion to
    Upgrade Status in Order No. 34651 was clearly erroneous and
    constituted an abuse of discretion.         LOL further argues that its
    “participant” status and the restriction of its participation to
    two issues in the 2017 Docket denied it a sufficient opportunity
    to protect its constitutional right to a clean and healthful
    environment, as defined by HRS Chapter 269.
    Hu Honua, HELCO, and the PUC argue that it was within
    the PUC’s discretion to find that LOL’s motion failed to satisfy
    the factors under HAR § 6-61-55 for party-intervenor status.
    HELCO additionally argues that LOL is time-barred from
    challenging the PUC’s denial because it did not do so within the
    thirty-day time period required by HRS § 91-14(b).             We conclude
    that LOL’s appeal of Order No. 34651 is timely, but we need not
    determine whether the PUC abused its discretion or violated LOL’s
    due process right in denying LOL’s Motion to Upgrade Status.
    a.     Timeliness of LOL’s Appeal of Order No. 34651
    Denying LOL’s Motion to Upgrade Status
    LOL’s appeal of Order No. 34651 is timely.             Under HRS
    § 91-14(b), appeals are timely where the appellant files its
    notice of appeal “within thirty days after service of the
    certified copy of the final decision and order of the agency[.]”
    HELCO cites Kilakila, 131 Hawaii at 
    195, 317 P.3d at 29
    , for the
    60
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    proposition that “denied requests to intervene are final orders
    as defined in HRS § 91-14,” and argues that Order No. 34651,
    which denied LOL’s Motion to Upgrade Status to party-intervenor,
    was a “final decision and order” subject to the thirty-day time
    limit under HRS § 91-14(b).       Because Order No. 34651 was issued
    on June 23, 2017 and LOL appealed that determination sixty-four
    days later on August 26, 2017, HELCO contends that LOL’s appeal
    is untimely.
    In Kilakila, this court considered whether the BLNR’s
    decision to approve a permit, without either granting or denying
    Kilakila’s request for a contested case hearing, was a “final
    decision and order” within the meaning of HRS § 91-14.              131
    Hawaii at 
    202-03, 317 P.3d at 36-37
    .         We noted that in
    Kaleikini, 124 Hawaii at 
    26, 237 P.3d at 1092
    , the “DLNR’s
    decision to deny Kaleikini’s request for a contested case hearing
    constituted a final decision and order of the agency because it
    ended the litigation.”      
    Id. at 203,
    317 P.3d at 37 (internal
    quotations omitted).     We then determined that the BLNR’s vote to
    grant the permit effectively denied Kilakila’s request for a
    contested case hearing, and was therefore a “final decision and
    order,” as it provided the requisite finality to enable Kilakila
    to appeal.     
    Id. Here, Order
    No. 34651 Denying LOL’s Motion to Upgrade
    Status was not required to be appealed within thirty days because
    it did not constitute a “final decision and order” of the PUC.
    61
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    The order denied LOL party status and confirmed LOL’s limited
    participant status, but did not resolve all other outstanding
    issues in the 2017 Docket.       Thus, unlike the agency decisions in
    Kaleikini and Kilakila, which provided appellants the “requisite
    finality” by “end[ing] the litigation[,]” the PUC’s Order No.
    34651 merely maintained LOL’s participation in the proceeding.
    See Kilakila, 131 Hawaii at 
    203, 317 P.3d at 37
    .            Therefore,
    LOL’s appeal would have been unripe until the PUC issued the 2017
    D&O, which represents the “final decision and order” of the PUC.
    The PUC issued the 2017 D&O on July 28, 2017, which, along with
    Order No. 34651 Denying LOL’s Motion to Upgrade Status, was
    appealed by LOL on August 26, 2017.         As LOL filed its notice of
    appeal twenty-nine days after the PUC’s 2017 D&O, its appeal is
    timely.
    b.     We Need Not Decide Whether the PUC Abused its
    Discretion or Violated Due Process by Denying
    LOL’s Motion to Upgrade Status
    HAR § 6-61-55 set forth nine factors for the PUC to
    consider in determining whether to grant a motion to intervene as
    a party in a PUC proceeding.        The rule further provided that the
    PUC would not grant intervention “except on allegations which are
    reasonably pertinent to and do not unreasonably broaden the
    issues already presented.”22        Pursuant to HAR § 6-61-55(a),

    intervention and the position and interest of
    the applicant.
    (b)   The motion shall make reference to:

    (2)   The nature and extent of the applicant’s
    property, financial, and other interest in
    the pending matter;
    (3)   The effect of the pending order as to the
    applicant’s interest;

    existing parties;
    (6)   The extent to which the applicant’s
    participation can assist in the
    development of a sound record;
    (7)   The extent to which the applicant’s
    participation will broaden the issues or

    “[i]ntervention as a party in a proceeding before the PUC is not
    a matter of right[,] but is a matter resting within the sound
    discretion of the commission[,]” as long as that discretion is
    not exercised arbitrarily or capriciously.            Application of
    Hawaiian Elec. Co., Inc., 
    56 Haw. 260
    , 262, 
    535 P.2d 1102
    , 1104
    (1975) (citation omitted).
    LOL argues that the limitation of its participation to
    Sub-issue Nos. 2.a.i and 2.b denied it a meaningful opportunity
    to address its constitutional right to a clean and healthful
    environment.     However, as discussed above, the record does not
    establish that the PUC explicitly considered the reduction of GHG
    emissions at all in the 2017 Docket.          It is therefore clear that
    the PUC misconstrued this aspect of its statutory duty, which was
    fundamental to LOL’s potential role in the proceeding.               As such,
    it appears the PUC’s denial of LOL’s Motion to Upgrade Status was
    premised on a flawed understanding of the relevant inquiry, and
    therefore we cannot say whether such denial constituted an abuse
    of discretion.
    LOL further argues that the PUC’s denial of its Motion
    to Upgrade Status violated its due process rights by impeding its
    ability to obtain access to documents.           However, the record does
    not establish that the PUC restricted LOL’s access to documents
    (...continued)
    (effective Jan. 1, 2019) is identical to HAR 6-61-55 (effective
    1992-2018).
    64
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    due to its status as a limited participant.           Order No. 34597,
    which established, inter alia, a final statement of the issues
    and LOL’s scope of participation in the 2017 Docket, limited
    LOL’s participation to Sub-issue Nos. 2.a.i and 2.b, but did not
    restrict the manner of its participation within those issues.
    Further, Protective Order No. 34555, which “govern[ed] the
    classification, acquisition, and use of trade secrets, and other
    confidential information” produced in the docket, provided that
    “[a]ll parties or participants to all or any portion of this
    docket . . . shall be entitled to all confidential information
    under the provisions of this Protective Order to the extent
    allowed by the commission.”       (Emphasis added).       LOL does not
    allege or demonstrate that access to documents designated as
    “confidential” was given to parties, but denied to participants.
    Accordingly, it is not apparent from the record that LOL would
    have had greater access to documents had the PUC granted its
    Motion to Upgrade Status.
    In sum, on remand, it is within the PUC’s discretion to
    determine the extent of LOL’s participation in the proceeding,
    pursuant to HAR § 16-601-55, provided that the PUC complies with
    its statutory and constitutional obligations to consider the
    reduction of GHG emissions and to allow LOL a meaningful
    opportunity to be heard regarding the Amended PPA’s impact on its
    right to a clean and healthful environment, as defined by HRS
    Chapter 269.
    65
    *** FOR PUBLICATION IN WEST’S HAWAII REPORTS AND PACIFIC REPORTER ***
    IV.   CONCLUSION
    As set forth above, HRS § 269-6(b) requires the PUC to
    expressly consider the reduction of GHG emissions in its
    decision-making.     The PUC failed to do so in determining whether
    the costs associated with the Amended PPA were reasonable, and in
    approving the Amended PPA.       The PUC also failed to afford LOL an
    opportunity to be heard at a meaningful time and in a meaningful
    manner regarding the Amended PPA’s impact on LOL’s property
    interest in a clean and healthful environment, as defined by HRS
    Chapter 269.
    The PUC’s 2017 D&O is therefore vacated and this case
    is remanded to the PUC for proceedings consistent with this
    opinion.
