    OPINION OF THE COURT BY RECKTENWALD, C.J.
    This case concerns a conservation district use permit
    for construction of the Advanced Technology Solar Telescope
    (ATST) on the island of Maui, in an area at the summit of
    Haleakalâ that was set aside for astronomical observatories in
    1961.     Haleakalâ is a site of great cultural and spiritual
    importance to the Native Hawaiian community.            It also bears
    scientific significance for astronomical studies, and is a
    popular visitor destination.
    The Board of Land and Natural Resources (Board or BLNR)
    granted a permit for the University of Hawai#i (UH) to construct
    the ATST.2    Kilakila #O Haleakalâ (Kilakila), an organization
    “dedicated to the protection of the sacredness of Haleakalâ[,]”
    challenged BLNR’s approval of the permit to construct the ATST.
    Kilakila appealed to the Circuit Court of the First Circuit and
    the Intermediate Court of Appeals, and both courts affirmed
    BLNR’s decision.
    This court granted certiorari review.          We conclude that
    the permit approval process was not procedurally flawed by
    prejudgment because BLNR’s initial permit was voided.              Nor was it
    flawed by impermissible ex parte communication because BLNR

    removed the original hearing officer after he communicated with a
    party, and the BLNR Chairperson’s meeting with non-parties did
    not address the merits of the permit approval process.              We
    further conclude that BLNR validly determined that the ATST met
    the applicable permit criteria and was consistent with the
    purposes of the conservation district.
    Accordingly, we conclude that BLNR properly granted the
    permit and affirm the ICA’s judgment.
    I.   Background
    A.    Haleakalâ, the Haleakalâ High Altitude Observatory, and the
    Proposed Advanced Technology Solar Telescope
    The summit of Haleakalâ has important cultural
    significance to Native Hawaiians.           Cultural assessments performed
    for the ATST determined that the Haleakalâ summit is one of the
    most sacred sites on Maui, and the Haleakalâ Crater is known as
    “where the gods live.”       The summit was traditionally used by
    Native Hawaiians as a place for religious ceremonies, for prayer
    to the gods, to connect to ancestors, and to bury the dead.
    Native Hawaiians continue to engage in some of these practices at
    the summit.
    The Haleakalâ summit consists of three volcanic cones,
    and all are partially developed.           One volcanic cone includes
    facilities belonging to the County of Maui, the State of Hawai#i,
    and the federal government.         The second cone houses Haleakalâ
    3
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    National Park’s popular visitor outlook.         In 1961, Hawai#i
    Governor William Quinn set aside 18.166 acres on the third
    volcanic cone, Pu#u Kolekole, as the site of the Haleakalâ High
    Altitude Observatory (HO).      Since this designation by Governor
    Quinn, the site has been used for astronomical observatories and
    is the only site at Haleakalâ used for these purposes.            The HO
    currently consists of eight research facilities “for advanced
    studies of astronomy and atmospheric sciences” owned by UH and
    managed by the UH Institute of Astronomy (UHIfA).
    The HO is located in a conservation district, as
    categorized by the State Land Use Commission.          Land within a
    conservation district is divided into subzones.          See HAR § 13-5-
    10 (1994).   The HO is in a “general subzone,” which seeks to
    “designate open space where specific conservation uses may not be
    defined, but where urban use would be premature.”           HAR § 13-5-
    14(a) (1994).   Several types of land use are permitted in the
    general subzone, including astronomical facilities.           See HAR
    § 13-5-24 (1994) (listing “[a]stronomy facilities under an
    approved management plan” as one of the allowable uses in a
    resource subzone); HAR § 13-5-25 (1994) (stating that “[i]n
    addition to the land uses identified [for general subzones], all
    identified land uses . . . for the protective, limited, and
    resource subzones also apply to the general subzone, unless
    otherwise noted”).
    4
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Over the past two decades, the proposed ATST was
    developed through the work of the Association of Universities for
    Research in Astronomy, the National Solar Observatory, and the
    National Science Foundation.           Astronomers and other scientists
    determined that there was a world-wide need for a telescope
    capable of taking high-resolution images of the sun to study its
    solar magnetic fields and its relation to solar energy, sunspots,
    and flares.       No current or planned ground-based or space-based
    telescope in the world has this capability.              The ATST would
    consist of an 142.7-feet tall telescope observatory structure, a
    support and operations building, a utility building, a parking
    lot, a wastewater treatment plant, and modifications to an
    existing observatory.         In 2004, after studying 72 potential
    sites, Haleakalâ was chosen as the best site for the ATST because
    it met or exceeded all requirements.
    B.    Application for Conservation District Use Permit
    The ATST requires a conservation district use permit
    (CDUP) because the HO is located in a conservation district.                    On
    March 1, 2010, UHIfA submitted a conservation district use
    application (CDUA) to BLNR pursuant to HAR § 13-5-31(a)3 and HAR
    3
    HAR § 13-5-31(a) (1994) details the requirements for a permit
    application:
    (1) A draft or final environmental assessment, draft
    or final environmental impact statement, or proof of
    an exemption or request for an exemption from the
    chapter 343, HRS, process, as applicable;
    (continued...)
    5
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    § 13-5-39(a)4.          The CDUA provided a range of detailed information
    about the ATST, including a final environmental impact statement
    (FEIS) and a management plan (MP).
    1.       Final environmental impact statement
    The FEIS5 was completed in July 2009 and addressed the
    environmental impacts associated with the construction and
    operation of the proposed ATST Project.6                The impacts were
    3
    (...continued)
    (2) Associated plans such as location map, site plan,
    floor plan, elevations, and landscaping plans drawn to
    scale;
    (3) The proposed land use shall address their
    relationship with county general plans and development
    plans;
    (4) Any other information as determined by the
    department;
    (5) Signature of the landowner;
    (6) Applicable fees;
    (7) A minimum of twenty copies (only one original copy
    required for site plan approvals) of the application
    and all attachments.
    4
    HAR § 13-5-39(a) (1994) states, “Where required, management plans
    shall be submitted with the board permit application[.]” A management plan
    was required for the ATST because the site is located in a general subzone.
    See HAR §§ 13-5-24,-25.
    5
    An environmental impact statement is “an informational document
    . . . which discloses the environmental effects of a proposed action, effects
    of a proposed action on the economic welfare, social welfare, and cultural
    practices of the community and State, effects of the economic activities
    arising out of the proposed action, measures proposed to minimize adverse
    effects, and alternatives to the action and their environmental effects.” HRS
    § 343-2 (Supp. 2008).
    6
    The FEIS was completed in accordance with several environmental
    laws:        (1) the Federal National Environmental Policy Act (NEPA) Title 42,
    U.S.C.       § 4321 and 40 CFR Parts 1500-1508, (2) Hawai#i Environmental Policy Act
    (HEPA)       HRS § 343 and HAR § 11-200, and (3) BLNR’s requirement for an EIS to
    obtain       a CDUP under HAR § 13-5-31(a)(1). The National Science Foundation was
    (continued...)
    6
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    “analyzed under three alternatives, two action alternatives
    located within HO:      the Mees Alternative (the Preferred
    Alternative) and the Reber Circle Alternative, and a No-Action
    Alternative.”
    The FEIS analyzed the environmental impacts from the
    ATST in the following categories:         (1) land use and existing
    activities, (2) cultural, historic, and archeological resources,
    (3) biological resources, (4) topography, geology, and soils, (5)
    visual resources and view planes, (6) visitor use and experience,
    (7) water resources, (8) hazardous materials and solid waste, (9)
    infrastructure and utilities, (10) noise, (11) climatology and
    air quality, (12) socioeconomics and environmental justice, (13)
    public services and facilities, and (14) natural hazards.7
    Most relevant to this appeal are the FEIS’s conclusions
    about the impacts on cultural and visual resources from the
    construction and operation of the ATST.          Regarding the cultural
    resources category, the FEIS determined:
    Construction and operation of the proposed ATST
    Project at either the Preferred Mees or Reber Circle
    sites would result in major, adverse, short- and
    long-term, direct impacts on the traditional cultural
    6
    (...continued)
    the lead agency responsible for completing the FEIS, and will be funding the
    construction of the ATST.
    7
    The FEIS reported the impacts in each category in several ways.
    The impacts were described as direct, indirect, or cumulative, and categorized
    as negligible, minor, moderate, or major. The FEIS also determined whether
    the impacts were long-term or short-term in duration. Lastly, the FEIS
    considered whether mitigation measures would reduce the duration, intensity,
    or scale of the impacts.
    7
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    resources within the ROI [Region of Influence8]. No
    indirect impacts are expected. Mitigation measures
    would be implemented; however, those measures would
    not reduce the impact intensity: impacts would remain
    major, adverse, long-term and direct.
    In addition, the FEIS found that “under the No-Action
    Alternative, there would continue to be major, adverse,
    long-term, direct impacts to traditional cultural resources.”
    In the visual resources and view planes category, the
    FEIS analyzed the impacts from two general viewpoint areas:              (1)
    land within Haleakalâ National Park and (2) various areas on the
    island of Maui, where the current HO facilities are visible.                 The
    FEIS determined that from either the preferred Mees site or the
    Reber Circle site, the direct impact on visual resources within
    the Park would be moderate, adverse, and long-term:
    No mitigation would adequately reduce this impact.
    The new structure would be visible to the point of
    co-dominance with other nearby structures. It would
    intensify the already developed appearance in its
    immediate surroundings, and would also appear to
    increase slightly the amount of horizontal space
    occupied by structures in views from within the Park.
    The new structure would not substantially alter the
    existing visual character visible in any view.
    Further, the FEIS concluded that from outside the Park,
    the impact of building the ATST at either the Mees site or the
    Reber Circle site “would result in minor, adverse and long-term
    impact to visual resources[,]” and therefore “[n]o mitigation
    would be necessary.”
    8
    “Region of Influence” refers to the HO site and surrounding areas,
    including Haleakalâ National Park.
    8
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    The FEIS also analyzed each category for cumulative
    impacts, defined as “impacts from past, present, and reasonably
    foreseeable future actions within the ROI . . . combined with the
    potential impacts from the proposed ATST Project.”            In the
    cultural resources category, the FEIS found that the cumulative
    impacts would be major, adverse, and long-term at either site and
    that implementation of mitigation measures would not reduce these
    impacts.    In the visual resources category, the FEIS found that
    the cumulative impacts would be major, adverse, and long-term
    from areas within the Haleakalâ National Park, and negligible,
    adverse, and long-term from other areas on Maui.
    2.    Management plan
    UHIfA submitted a draft MP with its CDUA on March 1,
    2010, and submitted the final MP to BLNR on June 8, 2010.9             The
    MP “is the governing document used for existing and future
    development at HO.”      It “specifies the design and environmental
    criteria that would be followed when implementing development,
    and presents strategies for managing, monitoring, and protecting
    the various natural and cultural resources[.]”
    The Executive Summary section of the MP summarized the
    strategies offered by UHIfA to protect cultural, historic, and
    9
    The MP was meant to supersede and replace the management planning
    policies and practices in UHIfA’s Long Range Development Plan (LRDP) from
    January 2005. The LRDP described the general conditions at the HO site, the
    principles behind the current and future scientific projects that UH planned
    at the HO site, and the planning process to protect the Haleakalâ summit.
    9
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    archeological resources:
    Monitoring strategies are presented to ensure the
    protection of cultural, historic, and archeological
    resources through policies, practices, and procedures
    developed in consultation with Native Hawaiian
    practitioners, agencies, interested individuals, and
    the Maui community, to ensure that historic
    preservation concerns are met. Monitoring strategies
    are also presented to prevent introduction of alien
    invasive species (AIS), to protect endangered species,
    and to educate all workers and contractors as to the
    potential impacts of construction and operations on
    the cultural and biological resources. Monitoring for
    construction practices to protect all resources at the
    site is described. Finally, the MP imposes certain
    design criteria on new facilities to minimize
    inappropriate design elements within the natural
    environment at the summit.
    A final environmental assessment (FEA) was completed on
    October 25, 2010.      The FEA examined the anticipated impacts from
    the MP’s implementation.        The purpose of the FEA was to “inform
    the relevant state agencies and the public of the likely
    environmental consequences of the MP on ongoing and future
    actions at HO in support of astronomical research.”             The FEA
    concluded that the MP would “either have beneficial, less than
    significant, or no impacts on the environment.”10
    C.    BLNR Administrative Proceedings
    BLNR’s review and ultimate approval of UHIfA’s
    application involved a series of events which are relevant to
    this appeal.     As set forth below, these included BLNR’s grant of
    a permit, Kilakila’s appeal of that permit, a contested case
    10
    The sufficiency of the FEA was challenged on appeal to this court
    in Kilakila #O Haleakalâ v. Univ. of Hawai#i, 134 Hawai#i 86, 
    332 P.3d 688

    hearing, ex parte communications involving the hearing officer,
    BLNR’s dismissal of that hearing officer and appointment of a new
    hearing officer, Kilakila’s motions for disclosure of any
    additional ex parte communications, the new hearing officer’s
    recommendation to BLNR, and BLNR’s grant of a second permit.
    1.    BLNR approval of the first ATST permit:          CDUP MA-3542
    On November 22, 2010, BLNR held its first public
    hearing on the ATST’s MP and CDUA.         On December 1, 2010, BLNR
    approved the MP and granted CDUP MA-3542 during its regular board
    meeting.    CDUP MA-3542 permitted the construction of the ATST,
    subject to several conditions.        Kilakila made three requests for
    a contested case hearing11 prior to and immediately after BLNR’s
    approval, and BLNR took no action on the requests.               Kilakila
    subsequently appealed to the circuit court, arguing that BLNR
    erred in denying Kilakila’s request for a contested case hearing
    11
    A contested case hearing is a quasi-judicial administrative
    hearing conducted pursuant to HAR § 13-1-28 (2009), which states:
    (a) When required by law, the board shall hold a
    contested case hearing upon its own motion or on a
    written petition of any government agency or any
    interested person.
    (b) The contested case hearing shall be held after any
    public hearing which by law is required to be held on
    the same subject matter.
    (c) Any procedure in a contested case may be modified
    or waived by stipulations of the parties.

    207, 317 P.3d at 41
    .
    2.    Contested case hearing
    While the appeal of CDUP MA-3542 was pending, BLNR
    granted Kilakila’s request for a contested case hearing, and on
    February 11, 2011, Steven Jacobson was appointed as the hearing
    officer.
    On June 2, 2011, Kilakila filed a motion to disqualify
    deputy attorneys general Linda Chow and Julie China from advising
    Jacobson or BLNR at the contested case hearing.           Kilakila
    asserted that Chow and China could not serve as counsel for BLNR
    because “[t]hey have filed documents in circuit court arguing
    that the BLNR could legally grant a conservation district use
    permit for the [ATST].”       On June 28, 2011, Jacobson denied
    Kilakila’s motion because he would not be relying on advice from
    Chow or China in making his recommendation to BLNR.            Jacobson
    dismissed the motion without prejudice so that Kilakila could
    renew its motion after Jacobson issued his recommendation to
    BLNR.
    The contested case hearing was held over four days,
    12
    That appeal ultimately resulted in this court’s decision in
    Kilakila I, in which we held that the circuit court had jurisdiction over the
    appeal pursuant to HRS § 91–14 and that Kilakila’s request for a contested
    case hearing should have been granted prior to BLNR’s approval of the permit.

    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    from July 18-20 and on August 26, 2011.         On February 23, 2012,
    Jacobson issued his proposed findings of fact, conclusions of
    law, and decision and order, recommending approval of the permit.
    On March 2, 2012, Kilakila renewed its motion, this
    time to BLNR, to disqualify Chow and China.          Kilakila argued that
    Chow and China have “appeared as adversaries to [Kilakila] at
    hearings regarding the conservation district use application.”
    On March 12, 2012, Jacobson issued his final findings of fact,
    conclusions of law, and decision and order, which recommended
    that BLNR approve the permit to construct the ATST.           On March 16,
    2012, BLNR denied Kilakila’s March 2, 2012 motion, noting that
    while Chow and China appeared as counsel for BLNR in a prior
    circuit court proceeding, “the appearance by the deputy attorneys
    general as counsel for the Board in that circuit court proceeding
    does not disqualify the deputy attorneys general from advising
    the Board in this administrative proceeding.”
    3.   Minute Order No. 14 regarding ex parte communication
    On March 19, 2012, BLNR filed Minute Order No. 14 “RE:
    EX PARTE COMMUNICATION[.]”      The order explained to the parties
    that BLNR had been notified that Jacobson sent an email to
    UHIfA’s counsel on March 15, 2012.        In the email, which was
    attached to the order, Jacobson stated that he had received
    “inappropriate ex parte pressure and activity by US Senator
    [Daniel] Inouye’s and the Governor’s offices” which “essentially
    13
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    required” him to submit an incomplete report and recommendation
    to BLNR.   Jacobson had contacted “appropriate ethical offices”
    and was informed that disclosures were not required where:
    (1) neither UHIfA nor its counsel had anything to do
    with what the Senator’s and Governor’s offices were
    doing, (2) the Board and courts disregard the interim
    [proposed] report and recommendations and consider
    only the final report and recommendations (to the
    extent they consider them at all), and (3) Kilakila is
    not prejudiced by being shortchanged in time to
    respond to the final report and recommendations.
    The email from Jacobson concluded with a question to
    UHIfA’s counsel as to “whether any of you had anything to do with
    what the Senator’s and Governor’s offices were doing.”
    BLNR’s order noted that the email between Jacobson and
    UHIfA’s counsel “was an unpermitted ex parte communication[,]”
    which “call[ed] into question the Hearing Officer’s impartiality”
    in relation to his report and recommendation to BLNR.               BLNR
    stated that it was considering the following actions in response
    to the ex parte communication:
    1. Striking the Report and Final and Amended Report
    from the record;
    2. Discharging the Hearing Officer, Steven Jacobson, as the
    hearing officer in this case; and
    3. Retaining a new hearing officer to review the
    record of the proceedings in this case and to issue a
    new hearing officer’s report and proposed findings of
    fact, conclusions of law, and decision and order. The
    new hearing officer would be authorized to conduct
    additional fact finding as necessary.
    BLNR scheduled a hearing and invited the parties to
    file comments or objections to the proposed actions.
    On March 20, 2012, Jacobson filed a response to BLNR’s
    14
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    order, describing what he characterized as the pressure placed on
    him by the Governor’s office to release his recommendation and to
    consult deputy attorney general Chow:
    In this file, while preparing my report and
    recommended decision, considerable ex parte pressure
    was placed upon me to simply spit out a recommended
    decision quickly, so that the Board would have
    something before it, to approve. That pressure
    included requiring me to make daily reports to both
    the Health Department and the Board’s Chair as to how
    soon I contemplated finishing, what else I thought I
    needed to do, why I thought I had to do it, etc.
    The pressure included a “suggestion” that Deputy
    General Chow be given a role in completing the
    decision.
    I was advised that the pressure was generated by
    a staffer in US Senator Inouye’s office, and applied
    through the Governor’s office. I was not asked to
    recommend a particular result, although the result
    Senator Inouye’s office wanted from the Board was
    clear. I did not see any evidence that anyone else
    (i.e., anyone in State Government), wanted any
    particular result, and the Board’s Chair, in
    particular, made clear that all he wanted to know was
    when this matter could be put on the Board’s calendar.
    My initial [proposed] report and recommended
    decision herein were filed as a result of “or else”
    pressure. The only way the pressure affected my
    initial [proposed] report and recommended decision was
    that they were incomplete. I made no substantive
    changes in light of comments by Ms. Chow.
    I then completed my final report and
    recommendations. In completing them, the only effect
    of the previous pressure upon me (which had been
    withdrawn) was that I very carefully went through
    everything UHIfA submitted, again, to be sure that I
    hadn’t missed something that those favoring the ATST
    Project might be hoping that I would miss.
    Again, nothing substantive was changed due to
    anything said by Ms. Chow. The final report and
    recommendations are entirely mine.
    UH responded to Minute Order No. 14 by “urg[ing]” BLNR
    to review the record and issue a decision without appointing a
    new hearing officer.     In the alternative, UH requested that:
    15
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    “(1) the additional fact finding should be limited to a site
    visit; and (2) the new Hearing Officer should be required to
    respond to the Board within a reasonable time frame.”              Kilakila
    also responded, requesting the appointment of a new hearing
    officer as well as disclosures of “any communications tending to
    show that external pressure was applied to affect the outcome of
    [the] proceeding.”
    4.   Minute Order No. 15 discharging hearing officer
    Jacobson
    On March 29, 2012, following a hearing on the issue of
    the ex parte communications, BLNR filed Minute Order No. 15,
    which discharged Jacobson and authorized the appointment of a new
    hearing officer “to avoid even the appearance of impropriety.”
    BLNR concluded that the email from Jacobson to UHIfA’s counsel
    was “an unpermitted ex parte communication in violation of
    Hawai#i Administrative Rules (HAR) § 13-1-37.”13         BLNR also struck
    13
    HAR § 13-1-37 (2009) provides:
    (a) No party or person petitioning to be a party in a
    contested case, nor the party’s or such person’s to a
    proceeding before the board nor their employees,
    representatives or agents shall make an unauthorized
    ex parte communication either oral or written
    concerning the contested case to the presiding officer
    or any member of the board who will be a participant
    in the decision-making process.
    (b) The following classes of ex parte communications
    are permitted:
    (1) Those which relate solely to matters which a
    board member is authorized by the board to dispose of
    on ex parte basis.
    (continued...)
    16
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Jacobson’s recommendation from the record and authorized the new
    hearing officer to make a ruling regarding Kilakila’s standing,
    issue a new recommendation within sixty days of appointment,
    schedule a site visit with the parties, hold additional
    evidentiary hearings as necessary, and consider a supplemental
    environmental assessment dated February 10, 2012.
    5.   Kilakila’s motion for disclosure
    On March 30, 2012, Kilakila filed a motion for
    disclosure of BLNR’s communications regarding the ATST.
    Kilakila’s motion sought:
    [T]o have each member of the BLNR disclose any and all
    communication (written, electronic and oral) that
    mentioned or related to the University’s proposed
    Advanced Technology Solar Telescope except for (a)
    communications between board members; (b)
    communications between any board member and the
    Board’s counsel; (c) any board meeting when the ATST
    was a subject matter of the agenda.
    The request included “any and all communication with
    Senator Inouye or his staff, the Governor or his staff,
    politicians, union leaders and members and construction industry
    representatives that mentioned or related to the [ATST].”
    In support of the motion, Kilakila cited hearing
    officer Jacobson’s statements regarding the ex parte
    13
    (...continued)
    (2) Requests for information with respect to the
    procedural status of a proceeding.
    (3) Those which all parties to the proceeding
    agree or which the board has formally ruled may be
    made on an ex parte basis.
    17
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    communications, as well as testimony from a former superintendent
    of Haleakalâ National Park who also noted pressures from Senator
    Inouye’s office regarding the ATST:
    While serving as superintendent, I was well
    aware of Senator Inouye’s displeasure with my
    statements/comments against the construction of the
    ATST. His staff assistant, James Chang placed heavy
    pressure on me to mute objections that the National
    Park Service had regarding the impacts of the ATST.
    For example, in a meeting with Mr. Chang, he strongly
    encouraged me to go along with the construction of the
    ATST project. When I stated it was my job to guard
    against such extreme impacts to this majestic national
    park, he indicated that he would go to the Secretary
    of the Interior to override my objections.
    UH opposed Kilakila’s motion, arguing that the request
    was a “fishing expedition” with no factual or legal basis.             In
    reply, Kilakila asserted that it was aware of at least one ex
    parte communication between a member of BLNR and the Governor’s
    office.   Kilakila attached emails obtained pursuant to a records
    request from the Governor’s office, which provided evidence of a
    meeting on March 21, 2012 between the Governor’s office, the
    Attorney General’s office, Senator Inouye’s office, and BLNR
    Chairperson William Aila to discuss the ATST.          These include a
    March 21, 2012 email between Bruce Coppa, the Governor’s chief of
    staff, and another staff member.         The staff member informs Coppa,
    “Jennifer [Sabas, Senator Inouye’s chief of staff,] requested a
    meeting today at 3 p.m. to discuss the telescope, hearings
    officer and funding issue.      AG will be coming in and Chair Aila
    is pending.”
    18
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    6.   Minute Order No. 23 partially granting Kilakila’s
    motion for disclosure
    On June 24, 2012, BLNR issued Minute Order No. 23
    granting Kilakila’s motion only “with regard to the meeting held
    on March 21, 2012[.]”     BLNR informed Kilakila and UHIfA that a
    meeting occurred on March 21, 2012, in which Aila participated.
    BLNR noted that “[d]uring the meeting the sole topic of
    discussion was when the recommended decision in this contested
    case would be issued by the hearing officer, Steven Jacobson.”
    BLNR concluded that no further action was warranted:
    Inasmuch as no party was present during the meeting,
    there was no ex parte communication with the hearing
    officer or any member of the Board. Even if a party
    were present, the discussion . . . comes within the
    purview of Hawai#i Administrative Rule (HAR) § 13-1-37
    as a permitted communication related to requests for
    information with respect to the procedural status of a
    proceeding. No further action is required regarding
    this communication.
    BLNR noted that Kilakila failed to “provide a time
    frame or context for the requested disclosures” and thus its
    “motion may encompass communications that occurred long before
    this matter was the subject of a contested case.”           BLNR further
    noted that Kilakila failed to show any communications beyond what
    was allowed under HAR § 13-1-37 and that its motion was “based,
    at most, upon mere speculation.”         Finally, BLNR concluded that it
    had not “acted in any manner other than as an impartial
    adjudicator” and that any prejudice to Kilakila had been
    rectified by the discharge and replacement of hearing officer
    19
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Jacobson.
    7.     Kilakila’s motion to reconsider Minute Order No. 23
    On June 8, 2012, Kilakila filed a motion to reconsider
    Minute Order No. 23.      Kilakila alleged that the “sole topic” of
    the March 21, 2012 meeting could not have been the timing of the
    release of Jacobson’s recommendation because Jacobson had already
    issued his initial and final decisions at this point.                Kilakila
    also requested communications between any member of BLNR and
    “anyone else” that related to the ATST:
    [F]or the sake of appellate court review, this Board
    should respond definitively as to whether or not there
    were any communications (oral, written or electronic)
    between any member of the Board and anyone else that
    mentioned or related to the University’s proposed
    Advanced Technology Solar Telescope with anyone
    (except for (a) communications between board members;
    (b) communications between any board member and the
    Board’s counsel; (c) any board member when the ATST
    was a subject matter on the agenda) from the time that
    Kilakila #O Haleakalâ requested a contested case
    hearing.
    On July 13, 2012, BLNR granted Kilakila’s motion in
    part, amending Minute Order No. 23:         “During the meeting, the
    sole topic of discussion was when the final decision in the
    contested case would be issued, in light of Minute Order No. 14
    [regarding Jacobson’s ex parte communication], filed on March 19,
    2012.”
    8.     Hearing officer Ishida’s recommendation
    On July 16, 2012, the new hearing officer, Lane Ishida,
    filed a report, proposed findings of fact and conclusions of law,
    20
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    decision, and order, which recommended that BLNR grant the CDUP,
    subject to several conditions.       To support her recommendation,
    Ishida made several findings, including that the ATST was
    consistent with the purposes of the conservation district and
    general subzone, would not cause substantial adverse impact to
    existing natural resources, and would not be materially
    detrimental to public health, safety, and welfare.
    9.   Kilakila’s second motion to reconsider Minute Order No.
    23
    On September 27, 2012, Kilakila filed a second motion
    to reconsider Minute Order No. 23.        Kilakila attached additional
    documents obtained from UH pursuant to a records request.             Most
    relevant to this appeal are six email communications, which are
    summarized as follows:
    •    January 30, 2012: Mike Maberry (UHIfA), emailed
    Jennifer Sabas, Senator Inouye’s chief of staff,
    regarding the ATST. Maberry stated that he knew
    that Sabas had already spoken with Aila, “but as
    previously mentioned, Steve Jacobsen [sic] doesn’t
    work for Aila he works for Fuddy. Would it be
    possible for you or someone to talk with Fuddy to
    see if it could be clarified that Steve’s work
    priority is to complete the Finding of Facts,
    Conclusions of Law and Recommendation in the ATST
    Contested Case?”
    •    January 30, 2012: In response to Maberry’s email,
    Sabas emailed Bruce Coppa, the Governor’s chief of
    staff, stating: “can you reach out to loretta
    fuddy who apparently the hearing officer is on
    contract with rather than dlnr––uh and my feds are
    getting really really nervous about losing the
    money for the atst.”
    21
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    •    January 30, 2012: Coppa responded to Sabas,
    stating: “I will speak with Loretta. I also spoke
    with Bill and asked to please help[.]”
    •    January 31, 2012: Sabas responded to Coppa
    noting, “Thanks. This will be bad if we lose it.”
    •    January 31, 2012: Maberry emailed Sabas regarding
    a potential meeting between the Governor’s office,
    Senator Inouye’s office, and BLNR regarding the
    ATST. Maberry noted that UH could not meet with
    BLNR until after BLNR acted on the hearing
    officer’s recommendation “or it could jeopardize
    the Contested Case.”
    •    January 31, 2012: Sabas responded to          Maberry
    regarding his inability to attend the         proposed
    ATST meeting and noted that she could         “carry the
    message and [could] also carry the uh         message.”
    Kilakila contended that these documents demonstrated
    that “the applicant has acted in bad faith; immense political
    pressure has been applied in this case that is even greater than
    prior documents had revealed; and Williams Aila Jr. has received
    more ex parte communication than has been previously revealed.”
    Kilakila then sought the following disclosure:
    At a minimum, the BLNR must disclose information about
    Bruce Coppa’s ex parte communication with William
    Aila, Jr. and Jennifer Sabas’ ex parte communication
    with William Aila, Jr. . . . If, in any of the ex
    parte communications, anyone communicated to any
    member of the Board the reasons that a decision needed
    to be expedited, this should be disclosed to Kilakila
    #O Haleakalâ.
    On November 9, 2012, BLNR issued an order denying
    Kilakila’s second motion to reconsider Minute Order No. 23.             BLNR
    noted that Kilakila “fails to show that any unpermitted ex parte
    communications occurred between the former hearing officer or any
    22
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Board members and one of the parties in this case that would be a
    basis to reconsider this Board’s prior Order No. 23.”
    10.   BLNR’s approval of the second ATST permit:             CDUP MA-11-
    04
    On November 9, 2012, BLNR issued its findings of fact,
    conclusions of law, decision and order approving a second permit
    for the ATST, CDUP MA-11-04.        BLNR made findings of facts
    concerning the parties to the contested case hearing, the
    procedural background of the permit application, the ATST project
    description, the Section 106 consultation14, the FEIS, and the
    anticipated benefits of the ATST.         BLNR then made conclusions of
    law under HAR § 13-5-30(c)(1)-(8) (1994), which provides the
    criteria for “evaluating the merits of a proposed land use” and
    granting a CDUP:
    (c) In evaluating the merits of a proposed land use,
    the department or board shall apply the following
    criteria:
    (1) The proposed land use is consistent with the
    purpose of the conservation district;
    (2) The proposed land use is consistent with the
    objectives of the subzone of the land on which the use
    will occur;
    (3) The proposed land use complies with
    provisions and guidelines contained in chapter 205A,
    HRS, entitled “Coastal Zone Management”, where
    applicable;
    (4) The proposed land use will not cause
    14
    In its order, BLNR explains, “Section 106 of the [National
    Historical Preservation Act] requires federal agencies to take into account
    the impacts of the agencies’ undertakings on historic properties and to afford
    the Advisory Council on Historic Preservation . . . a reasonable opportunity
    to comment on such undertakings.”
    23
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    substantial adverse impact to existing natural
    resources within the surrounding area, community, or
    region;
    (5) The proposed land use, including buildings,
    structures, and facilities, shall be compatible with
    the locality and surrounding areas, appropriate to the
    physical conditions and capabilities of the specific
    parcel or parcels;
    (6) The existing physical and environmental
    aspects of the land, such as natural beauty and open
    space characteristics, will be preserved or improved
    upon, whichever is applicable;
    (7) Subdivision of land will not be utilized to
    increase the intensity of land uses in the
    conservation district; and
    (8) The proposed land use will not be materially
    detrimental to the public health, safety, and welfare.
    The applicant shall have the burden of demonstrating
    that a proposed land use is consistent with the above
    criteria.
    “Based upon the evidence and testimony presented in
    this case,” BLNR concluded that the ATST satisfied each of the
    eight criteria, UH “met its overall burden of proof[,]” and a
    CDUP for ATST was approved, subject to twenty conditions.
    D.     Circuit Court Proceedings
    Kilakila appealed BLNR’s decision to the Circuit Court
    of the First Circuit.15       On July 11, 2013, after holding oral
    argument and reviewing the parties’ briefings, the circuit court
    issued its Order affirming BLNR’s decision to grant CDUP MA-11-
    04.    The circuit court filed its Final Judgment on August 20,
    2013.
    15
    The Honorable Rhonda A. Nishimura presided.
    24
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    E.    ICA Proceedings
    Kilakila appealed to the Intermediate Court of
    Appeals.16    The ICA rejected each of Kilakila’s points of error
    in its October 17, 2014 Memorandum Opinion, which affirmed the
    circuit court’s judgment and BLNR’s decision.               The ICA’s Judgment
    on Appeal was filed on November 13, 2014.            Kilakila timely
    applied for writ of certiorari on December 1, 2014.
    II.   Standards of Review
    Appellate court review of a circuit court’s review of
    an administrative decision is a secondary appeal.                “The standard
    of review is one in which this court must determine whether the
    circuit court was right or wrong in its decision, applying the
    standards set forth in HRS § 91-14(g) (1993) to the agency’s
    16
    Kilakila contended that the circuit court erred because:
    (1) the Board’s approval did not comply with Hawai#i
    Administrative Rules (HAR) § 13-5-3(c) (1994);
    (2) the Board erred by considering economic factors;
    (3) the Board erred by weighing the lack of
    alternatives against the Solar Telescope’s adverse
    impacts,
    (4) the correct entity did not apply for the
    conservation district use permit (CDUP),
    (5) the Solar Telescope is inconsistent with the June
    8, 2010 Management Plan (Management Plan) prepared by
    the University of Hawai#i Institute for Astromony
    (UIA),
    (7)[sic] the Board violated Kilakila’s procedural due
    process rights; and
    (8)[sic] the Board acted pursuant to unauthorized
    procedure.

    III.   Discussion
    Kilakila’s application for writ of certiorari raises
    several issues,17 many of which overlap or were raised without
    17
    Kilakila’s application raised the following thirteen points of
    error:
    1. Did the ICA err in affirming the Circuit Court’s
    affirmation of the BLNR’s decision? More
    specifically, the questions presented include:
    2. Did the ICA err when it held that an agency can
    use decisionmaking criteria that are not identified in
    its own rules––despite this Court’s rulings in Aluli
    v. Lewin,

    of certiorari shall contain a “short and concise statement of the
    questions presented” and a “brief argument with supporting
    authorities”).    Therefore, we address the following questions,
    which we consider controlling and dispositive:
    (1) Did the ICA err in concluding that the permit
    approval process was not procedurally flawed,
    specifically that BLNR did not prejudge CDUP MA-11-04
    and was not improperly influenced by ex parte
    communications?
    (2) Did the ICA err in concluding that BLNR’s findings

    7. Did the ICA err in interpreting HAR §
    13-5-30(c)(6) in a manner that excludes consideration
    of natural beauty and open space characteristics?
    8. Did the ICA err in assuming that the lease of a
    portion of land does not subdivide it despite the
    plethora of law to the contrary?
    9. Did the ICA err in holding that the ATST project
    is consistent with a valid management plan?
    10. Did the BLNR prejudge the issue by granting the
    CDUP before the contested case was held and then
    authorizing some construction activities to proceed
    pursuant to that permit prior to completion of the
    post hoc contested case hearing?
    11. Did the ICA err in relying on HRS § 171-6(20) to
    justify the BLNR’s conduct pursuant to HRS chapter
    183C when chapter 183C is not part of HRS chapter 171?
    12. Was the BLNR’s post hoc contested case hearing
    tainted by political pressure, ex parte communication,
    the refusal to fully and timely disclose the extent of
    ex parte communication, the dual role of the deputy
    attorney general as adversary and advisor to the
    tribunal, and the arbitrary deletion of key findings
    by the hearing officer?
    13. Did the ICA err in holding that the applicant was
    authorized to apply for the permit?
    29
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    under HAR § 13-5-30(c)(4),(5), and (6) were valid?
    (3) Did the ICA err in concluding that the ATST was
    not inconsistent with the purposes of conservation
    districts and general subzones?
    A.    The permit approval process did not suffer from procedural
    infirmities
    Kilakila alleges that the approval process for CDUP MA-
    11-04 suffered from two procedural defects:            (1) BLNR prejudged
    the permit approval and (2) BLNR engaged in impermissible ex
    parte communications and failed to disclose them.             We address
    each of these issues below.
    1.    BLNR did not prejudge the permit prior to the contested
    case hearing
    Before addressing the issue of prejudgment, it is
    necessary to review the underlying sequence of events.              At the
    first public hearing regarding the ATST’s CDUA, Kilakila
    requested that BLNR conduct a contested case hearing.              Without
    granting Kilakila’s request, BLNR approved the first permit for
    the construction of the ATST, CDUP MA-3542.            Kilakila then
    appealed BLNR’s decision to grant the permit prior to holding a
    contested case hearing.
    That appeal resulted in this court’s decision in
    Kilakila I, in which we held that the circuit court had
    jurisdiction over the appeal pursuant to HRS § 91-14 and that
    Kilakila’s request for a contested case hearing should have been
    granted prior to BLNR’s approval of the permit.            131 Hawai#i at
    30
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    
    205-06, 317 P.3d at 39-40
    .       We remanded to the circuit court
    regarding Kilakila’s request for stay or reversal of CDUP
    MA-3542.    
    Id. at 206,
    317 P.3d at 40.       On remand, the parties
    entered into a stipulation, titled “Stipulation That the
    Conservation District Use Permit (CDUA MA-3542) Is Void”:18
    IT IS HEREBY STIPULATED by and amongst the parties
    described below, through their respective undersigned
    counsel that the conservation district use permit
    (CDUA MA-3542) granted by the Board of Land and
    Natural Resources and the Department of Land and
    Natural Resources in December 2010 is void.
    This stipulation ended the appeal.
    While the appeal regarding CDUP MA-3542 was pending,
    BLNR granted Kilakila’s request for a contested case hearing.
    After the contested case hearing, on November 9, 2012, BLNR
    issued an order approving a second permit for the construction of
    the ATST, CDUP MA-11-04.       It is that permit that is the subject
    of the instant appeal.
    Kilakila now asserts that BLNR prejudged the permit at
    issue in this case, CDUP MA-11-04, because it approved
    construction prior to the completion of the contested case
    18
    The stipulation was not included in the record for this case, but
    in the record of the pending case Kilakila #O Haleakalâ v. Univ. of Hawai#i,
    134 Hawai#i 86, 
    332 P.3d 688
    (App. 2014), cert. granted, SCWC-13-0000182
    (Sept. 12, 2014). We may therefore take judicial notice of the stipulation.
    See Hawai#i Rules of Evidence 201(b) (“A judicially noticed fact must be one
    not subject to reasonable dispute that is . . . capable of accurate and ready
    determination by resort to sources whose accuracy cannot be reasonably be
    questioned.”); see also State v. Puaoi, 78 Hawai#i 185, 190, 
    891 P.2d 272
    , 277
    (1995) (“[A]n appellate court may take judicial notice of facts despite the
    failure of the trial court to do so, provided that the facts are capable of
    immediate and accurate demonstration by resort to easily accessible sources of
    indisputable accuracy.”) (internal quotation marks and citation omitted).
    31
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    hearing.   However, this construction was for the removal of an
    unused foundation at the Reber Circle site.          BLNR did not approve
    any construction of the ATST itself.        The removal of the unused
    foundation was previously supported by Kilakila and was required
    by other agreements, such as the Archaeological Recovery Plan
    that BLNR approved in 2006.      Furthermore, no construction
    ultimately occurred prior to the completion of the contested case
    hearing.
    Kilakila also argues that BLNR prejudged the second
    permit, CDUP MA-11-04, by voting on the first permit, CDUP MA-
    3542, prior to a contested case hearing.         The issue of
    prejudgment was recently addressed by this court in Mauna Kea
    Anaina Hou v. Bd. of Land & Nat. Res., 136 Hawai#i 376, 
    363 P.3d 224
    (2015), in which we held that BLNR’s decision to approve a
    permit prior to a contested case hearing violated appellants’ due
    process rights.    
    Id. at 391;
    363 P.3d at 239.        This case is
    dissimilar to Mauna Kea, insofar as here Kilakila entered into a
    stipulation with BLNR and UH to void the first permit.            Since
    BLNR’s initial approval of CDUP MA-3542 was voided, appellants’
    due process rights were adequately protected by the contested
    case hearing and subsequent vote by BLNR.         See Hawai#i Elec.
    Light Co. v. Dep’t of Land & Nat. Res., 102 Hawai#i 257, 266, 
    74 P.3d 160
    , 169 (2003) (holding that, when BLNR’s initial vote on a
    permit was later invalidated, “the constitutional right of due
    32
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    process was adequately protected through the contested case
    hearing process and the subsequent votes by the Board”).
    Indeed, the stipulation rendered the first permit “of
    no validity or effect.”     Black’s Law Dictionary 1805 (10th ed.
    2014) (defining “void” as “[t]o render of no validity or effect;
    to annul”).    Because the first permit was deemed invalid by the
    stipulation, Kilakila received the relief sought in its previous
    appeal.    Kilakila cannot now seek to vacate the second permit
    based on the first permit, which Kilakila voluntarily stipulated
    to void.
    In sum, the permit approval process for CDUP MA-11-04
    met procedural due process requirements.         BLNR did not approve
    any construction of the ATST itself prior to the completion of
    the contested case hearing.      Since BLNR’s initial approval was
    voided, appellants’ due process rights were protected by the
    contested case hearing and subsequent vote by BLNR.
    2.     Ex parte communications with BLNR were not improper
    Kilakila argues that the ICA erred in concluding that
    BLNR’s permit approval process was not subject to impermissible
    ex parte political pressure.      Kilakila alleges that the Governor
    and Senator Inouye’s offices exerted pressure on BLNR Chairperson
    Aila in order to attain approval of the telescope, and that BLNR
    failed to disclose these ex parte communications.
    The ICA rejected Kilakila’s argument on the basis that
    33
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    BLNR promptly removed Jacobson as the hearing officer and
    disregarded his recommendation, curing any allegation of
    partiality involving Jacobson.       The ICA also noted that Kilakila
    did not contend that hearing officer Ishida, who ultimately made
    the recommendation to BLNR, was subject to any ex parte
    communication or political pressure.
    We agree with the ICA that any concern of impropriety
    was cured when BLNR replaced Jacobson with Ishida.           Indeed, this
    is precisely the relief that Kilakila requested.
    However, the ICA did not consider whether any ex parte
    communications involving Aila tainted the permit approval process
    or whether BLNR improperly denied Kilakila’s discovery requests
    for additional communications involving the ATST.           Though we note
    that Kilakila never moved to disqualify Aila as it did with
    Jacobson, we address these questions now.
    The communications at issue here are:          (1) the March
    21, 2012 meeting between Aila, the Governor’s office, the
    Attorney General’s office, and Senator Inouye’s office, (2) the
    January 30-31, 2012 emails between Jennifer Sabas of Senator
    Inouye’s office and Mike Maberry of UHIfA, and (3) the January
    30-31, 2012 emails between Sabas and Bruce Coppa of the
    Governor’s office.
    We first determine whether the communications violated
    the relevant administrative rule, HAR § 13-1-37.           HAR § 13-1-37
    34
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    governs ex parte communication in contested case proceedings and
    provides:
    (a) No party or person petitioning to be a party in a
    contested case, nor the party’s or such person’s to a
    proceeding before the board nor their employees,
    representatives or agents shall make an unauthorized
    ex parte communication either oral or written
    concerning the contested case to the presiding officer
    or any member of the board who will be a participant
    in the decision-making process.
    (b) The following classes of ex parte communications
    are permitted:
    (1) Those which related solely to the matters
    which a board member is authorized by the board to
    dispose of on ex parte basis.
    (2) Requests for information with respect to
    the procedural status of a proceeding.
    (3) Those which all parties to the proceeding
    agree or which the board has formally ruled may be
    made on an ex parte basis.
    HAR § 13-1-37 does not apply to the January 30-31, 2012
    communications because they were not sent to “any member of the
    board who will be a participant in the decision-making process.”
    HAR § 13-1-37(a).     Nor would it apply to the March 21, 2012
    meeting between Aila, the Governor’s office, the Attorney
    General’s office, and Senator Inouye’s office.           Although Aila was
    a “member of the board” as BLNR Chairperson, the other meeting
    participants were not “part[ies] . . . to a proceeding” or a
    party’s “employees, representatives or agents.”           HAR § 13-1-37(a)
    (emphasis added).     There is no evidence that UH or Kilakila
    attended the meeting.
    Even if the Governor’s office and Senator Inouye’s
    35
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    office were considered “representatives or agents” of UH, the
    meeting would not violate HAR § 13-1-37 because the “sole topic”
    of the discussion during the meeting was the timing of BLNR’s
    final decision following the contested case hearing.            The timing
    of BLNR’s decision falls under the category of permitted ex parte
    communications, as “[r]equests for information with respect to
    the procedural status of a proceeding.”         HAR § 13-1-37(b)(2).
    Though the communications were not impermissible ex
    parte communications in violation of HAR § 13-1-37, they may
    nevertheless demonstrate that improper outside influences tainted
    BLNR’s permit approval.      In In re Water Use Permit Applications
    (Waiâhole), this court determined whether external political
    pressure on an agency violated due process and invalidated the
    agency’s decision.     94 Hawai#i 97, 123, 
    9 P.3d 409
    , 435 (2000).
    We noted:
    External political inference in the administrative
    process is of heightened concern in a quasi-judicial
    proceeding, which is guided by two principles. First,
    the appearance of bias or pressure may be no less
    objectionable than the reality. Second, judicial
    evaluation of the pressure must focus on the nexus
    between the pressure and the actual decision maker.
    As we have previously observed, the proper focus is
    not on the content of communication in the abstract,
    but rather upon the relation between the
    communications and the adjudicator’s decisionmaking
    process.
    
    Id. (internal quotation
    marks, brackets, and citations omitted;
    emphases in original).
    This court then evaluated an allegation of improper
    36
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    political pressure based on these principles.          The petitioner in
    Waiâhole alleged that the Governor exerted improper influence on
    the Commission on Water Resource Management by publicly
    criticizing the Commission’s proposed decision.          
    Id. Consistent with
    the focus on “the relation between the communications and
    the adjudicator’s decisionmaking process,” this court noted that
    other instances of improper political influence involved “at
    minimum, some sort of direct contact with the decisionmaker
    regarding the merits of the dispute.”        
    Id. (emphases added).
    The Governor’s comments in Waiâhole did not meet this
    minimum standard.    Although the Governor had made several
    statements that “related directly to the dispute before the
    Commission,” there was not sufficient evidence of “direct and
    focused interference” in the Commission’s decision-making.             
    Id. at 124,
    9 P.3d at 436.     Thus, there was not a nexus between the
    Governor’s comments and the Commission that demonstrated improper
    pressure on the Commission’s decision.         
    Id. at 124-25,
    9 P.3d at
    436-37.
    Similar to Waiâhole, the communications here do not
    show evidence of “direct contact” with BLNR over the “merits of
    the dispute.”   The January 30-31, 2012 emails do not discuss the
    merits of the contested case hearing.        Rather, as the ICA
    described, the emails appear to indicate concerns over “the
    possibility of losing funding for the [ATST] if construction did
    37
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    not begin by a certain date.”        The email communications are also
    unclear on whether there was any direct contact with Aila.              Only
    one email mentions Aila and states that “[Coppa, the Governor’s
    chief of staff] spoke with [Aila] and asked to please help.”                 The
    Governor’s office and Senator Inouye’s office did have direct
    contact with Aila at the March 21, 2012 meeting, but there is no
    evidence that they discussed anything other than the timing of
    BLNR’s final decision following the contested case hearing.19
    Undoubtedly, the public criticisms in Waiâhole and the
    timing concerns voiced here both placed pressure on the
    respective agencies.      However, the question is not whether there
    was any pressure placed on the agency, but whether the pressure
    was directed at the merits of the agency’s decision.             While the
    communications here concerned the permit approval process for the
    ATST and therefore “related directly to the dispute before” BLNR,
    we are not presented with evidence of communications relating to
    the merits that would constitute “direct and focused
    interference” in BLNR’s decision-making.          
    Id. at 124,
    9 P.3d at
    436.   In sum, we do not find that the political pressure placed
    19
    The March 21, 2012 email from a member of the Governor’s staff to
    Coppa stated that “[Sabas] requested a meeting today at 3 p.m. to discuss the
    telescope, hearings officer and funding issue.” Similar to the January 30-31,
    2012 emails, the email indicates an interest in knowing when the final BLNR
    decision will be made given funding deadlines. It was also sent prior to the
    March 21, 2012 meeting by someone who appears to have helped schedule the
    meeting, but did not actually attend it. Thus, the fact that this email
    mentions “funding” does demonstrate that Aila discussed the merits of the case
    at the March 21, 2012 meeting.
    38
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    on BLNR rose to the level of impropriety.
    We now turn to Kilakila’s three requests for
    communications regarding the ATST.         In its March 30, 2012 motion
    for disclosure, its June 12, 2012 motion to reconsider Minute
    Order No. 23, and its September 27, 2012 second motion to
    reconsider Minute Order No. 23, Kilakila sought the release of
    oral, written, and electronic communications involving BLNR
    members.    Kilakila was specifically concerned with ex parte
    communications involving Aila, though it never moved to
    disqualify Aila or any other BLNR member.         BLNR provided
    information about the March 21, 2012 meeting in response to the
    first two requests, and dismissed the third request outright.
    We have concerns about BLNR’s handling of Kilakila’s
    requests.    For example, in light of Kilakila’s receipt of the
    January 30-31, 2012 emails, BLNR could have granted discovery
    limited to the parties involved in the emails, rather than
    dismissing the request outright.         In future contested case
    hearings, BLNR could certainly do more to remove doubts of
    impropriety and build confidence in its permit approval process.
    Despite these concerns, we cannot say that BLNR abused
    its discretion when it denied Kilakila’s requests.           “[A]
    determination made by an administrative agency acting within the
    boundaries of its delegated authority will not be overturned
    unless ‘arbitrary, or capricious, or characterized by . . . [a]
    39
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    clearly unwarranted exercise of discretion.’”          Paul’s Elec.
    Serv., 104 Hawai#i at 
    419, 91 P.3d at 501
    (citing HRS §
    91-14(g)(6)); see also Save Diamond Head Waters, 121 Hawai#i at
    
    24, 211 P.3d at 82
    (stating that an agency’s exercise of
    discretion is reviewable under the arbitrary and capricious
    standard).
    BLNR had broad discretion over Kilakila’s discovery
    requests, and it did in fact provide additional information in
    response to the requests.      See Hawai#i Ventures, LLC v. Otaka,
    Inc., 114 Hawai#i 438, 472, 
    164 P.3d 696
    , 730 (2007) (stating
    that courts have “considerable latitude and discretion” over
    discovery requests).     In its Minute Order No. 23, BLNR disclosed
    the participants and nature of the March 21, 2012 meeting.
    Later, BLNR clarified that the meeting’s topic of discussion
    concerned the timing of BLNR’s decision in light of the dismissal
    of hearing officer Jacobson.      Contrary to Kilakila’s argument,
    BLNR was not required to provide all of the disclosures sought in
    the requests.   See 
    id. (determining that
    the circuit court did
    not abuse its discretion when it “did not grant all of the
    requests for discovery[,]” but did require an opposing party
    provide a financial statement which addressed concerns of
    improper payment underlying the discovery requests).
    BLNR also provided its reasoning for not disclosing
    more information.    It concluded that Kilakila’s first request was
    40
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    too broad, noting that it did not provide a time frame for the
    request and encompassed communications beyond the subject of the
    contested case hearing.       BLNR also concluded that Kilakila failed
    to show any improper ex parte communications, and as discussed
    above, we agree that the communications did not constitute an
    impermissible ex parte communication in violation of HAR § 13-1-
    37 or an improper political influence under the reasoning in

    In circumstances such as these, we have never held that procedural
    communications with agency officials raise due process concerns. Thus, we
    need not employ any constitutional analysis, but instead must refer to the
    applicable statute and administrative rule, neither of which preclude
    procedural communications. See HRS § 91-13 (“No official of an agency who
    renders a decision in a contested case shall consult any person on any issue
    of fact except upon notice and opportunity for all parties to participate,
    save to the extent required for the disposition of ex parte matters authorized
    by law.”) (emphasis added); HAR § 13-1-37. The communications here were
    permissible as they did not address the merits of the contested case or any
    issues of fact. Given that this issue involves a question of administrative
    law, the appropriate standard of review of BLNR’s denial of Kilakila’s
    disclosure requests is abuse of discretion. See Paul’s Elec. Serv., 104
    Hawai#i at 
    419, 91 P.3d at 501
    .

    brackets omitted).
    Therefore, we cannot conclude that BLNR abused its
    discretion.     However, we caution public officials and other
    interested parties that contacts of the type involved here carry
    significant risk of creating the appearance of impropriety,
    and––as Jacobson’s filings indicate––of having an effect on the
    process.
    B.    BLNR properly analyzed the criteria under HAR § 13-5-30
    Kilakila argues that BLNR’s decision to grant the
    permit was not supported by the evidence and does not satisfy HAR
    § 13-5-30(c), which provides eight criteria that BLNR must
    consider prior to approving a permit.          Specifically, Kilakila
    argues that the ICA erred in affirming BLNR’s findings under HAR
    § 13-5-30(c)(4), (5), and (6).         We address these three criteria
    below.
    1.    BLNR did not err in determining that the ATST would
    not have a substantial adverse impact under HAR
    § 13-5-30(c)(4)
    HAR § 13-5-30(c)(4) states:        “The proposed land use
    will not cause substantial adverse impact to existing natural
    resources within the surrounding area, community, or region[.]”
    “Natural resource” is defined as “resources such as plants,
    aquatic life and wildlife, cultural, historic, recreational,
    geologic, and archeological sites, scenic areas, ecologically
    significant areas, watersheds, and minerals.”            HAR § 13-5-2.
    42
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Kilakila argues that the ICA erred in
    “rubberstamp[ing]” BLNR’s findings of no substantial adverse
    impact on existing natural resources, specifically cultural and
    visual resources.    Kilakila argues that the ICA, the circuit
    court, and BLNR erred by failing to cite any evidence that the
    impacts to cultural resources would be less than substantial and
    that mitigation measures would reduce the intensity of the
    impacts.   Kilakila further asserts that BLNR erred in
    disregarding certain findings in the FEIS to conclude that the
    ATST would not have a substantial impact on scenic vistas.
    Despite Kilakila’s contentions, we do not find that
    BLNR’s treatment of the FEIS and its analysis under HAR
    § 13-5-30(c)(4) was clearly erroneous.         See Save Diamond Head
    Waters, 121 Hawai#i at 
    25, 211 P.3d at 83
    (“A conclusion of law
    that presents mixed questions of fact and law is reviewed under
    the clearly erroneous standard[.]”).
    It is undisputed that the FEIS concluded that there
    would be adverse impacts on cultural and visual resources from
    the construction and operation of the ATST.          The FEIS determined
    that there would be “major, adverse, short- and long-term, direct
    impacts” on cultural resources and that mitigation measures
    “would not reduce the impact intensity[.]”         It also determined
    that the direct impact on visual resources within the Haleakalâ
    National Park would be “moderate, adverse and long-term” and that
    43
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    “[n]o mitigation would adequately reduce this impact.”            From
    outside the Park, the impact of building the ATST “would result
    in minor, adverse and long-term impact to visual resources[,]”
    and therefore “[n]o mitigation would be necessary.”
    Kilakila suggests that the FEIS findings required BLNR
    to determine that HAR § 13-5-30(c)(4) was not satisfied.            While
    BLNR was required to consider the findings in the FEIS, it was
    not bound by these findings and still retained discretion over
    its decision.   See Mauna Kea Power Co. v. Bd. of Land & Nat.
    Res., 76 Hawai#i 259, 265, 
    874 P.2d 1084
    , 1090 (1994) (affirming
    BLNR determination despite conflicting conclusions in EIS).              In
    other words, BLNR was not required to conclude that the ATST
    would not satisfy HAR § 13-5-30(c)(4) solely because the FEIS
    determined there would be major adverse impacts on cultural
    resources.   Rather, an environmental impact statement is “merely
    an informational document,” and its findings neither presume
    approval nor denial of a conservation district use application.
    Id.; see also HRS § 343-2 (defining “environmental impact
    statement” as “an informational document”).
    As such, in making its decision to grant the permit,
    BLNR properly considered the FEIS, along with the information
    provided by the permit application, the site visits and maps, the
    public hearing testimony, the contested case hearing testimony
    and evidence, the hearing officer’s recommendation, and other
    44
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    documents.   See HAR §§ 13-5-31, 13-5-40 (1994), 13-1-28; see also
    Camara v. Agsalud, 
    67 Haw. 212
    , 216, 
    685 P.2d 794
    , 797 (1984)
    (“[I]n deference to the administrative agency’s expertise and
    experience in its particular field, the courts should not
    substitute their own judgment for that of the administrative
    agency where mixed questions of fact and law are presented.             This
    is particularly true where the law to be applied is not a statute
    but an administrative rule promulgated by the same agency
    interpreting it.”) (citation omitted).
    Next, Kilakila argues that BLNR did not sufficiently
    explain how it reached its decision despite the conflicting
    findings in the FEIS.     More specifically, Kilakila asserts that
    BLNR should have provided “supporting analytical data” for its
    decision, rather than “a perfunctory description or mere listing
    of mitigation measures[.]”      Kilakila takes this language from
    Makua v. Rumsfeld, in which the U.S. District Court for the
    District of Hawai#i concluded that a supplemental environmental
    assessment’s finding of no significant impact on endangered
    species “contain[ed] no analysis or evidence of the effectiveness
    of [the] mitigation measures” and therefore was insufficient.
    
    163 F. Supp. 2d 1202
    , 1218 (D. Haw. 2001).
    In addition to not being binding on this court, Makua
    is not analogous because the issue in that case was whether an
    environmental impact statement should have been prepared.             
    Id. at 45
       *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    1216.   Here, an environmental impact statement was completed, and
    BLNR subsequently determined “[b]ased upon the evidence and
    testimony presented in this case, and the files and records
    herein,” that a permit approval was warranted.          Furthermore, this
    court has never required an agency to provide “supporting
    analytical data” to uphold its findings. Instead, our court
    requires that “where the record demonstrates considerable
    conflict or uncertainty in the evidence, the agency must
    articulate its factual analysis with reasonable clarity, giving
    some reason for discounting the evidence rejected.”           Waiâhole, 94
    Hawai#i at 
    163-64, 9 P.3d at 475-76
    (emphasis added).
    We therefore consider whether BLNR articulated with
    reasonable clarity why the ATST would not result in a substantial
    adverse impact on natural resources, despite the apparently
    conflicting findings in the FEIS.
    BLNR noted that “[t]he impacts of the ATST Project must
    be viewed in the context of the HO site[,]” which has “housed
    astronomy facilities since the 1950’s and was specifically
    created for astronomy uses.”      There are eleven facilities
    currently located within the HO site, and the ATST would leave
    only one vacant location, the Reber Circle site.
    Due to these existing facilities in the HO, the FEIS
    found that there would be “major, adverse, long-term, direct
    impacts” on cultural resources even under the No-Action
    46
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Alternative.   The No-Action Alternative refers to the scenario in
    which “no construction [of the ATST] would take place and
    operations [in the HO] would continue unaltered.”           These impacts
    are almost identical to the impacts that would result from the
    construction of the ATST, which the FEIS described as “major,
    adverse, short- and long-term, direct.”         Therefore, regardless of
    whether or not the ATST was constructed, the FEIS determined that
    there would be major, adverse impacts on cultural resources.
    Consistent with this finding in the FEIS, BLNR
    concluded that “because of the past construction of man made
    structures[,]” the ATST’s additional impact on cultural resources
    would be “incremental[.]”      BLNR concluded that the impact on
    visual resources would be similarly incremental:           “[T]he ATST
    would be visible to a point of co-dominance with other nearby
    structures” and “would not substantially alter the existing
    visual character visible in any view.”         In other words, BLNR
    concluded that the ATST would have an impact on cultural and
    visual resources, but given the existing buildings in the HO,
    BLNR concluded that the impact would not be substantial.
    BLNR also considered mitigating measures when
    determining whether ATST would have a substantial adverse impact
    on natural resources.     In the CDUA, UHIfA committed to mitigation
    measures “intended to reduce the duration, intensity or scale of
    impacts or to compensate for the impact by replacing or providing
    47
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    substitute resources or environments.”          The measures specifically
    directed at reducing cultural and visual impacts included
    creating a Native Hawaiian Working Group to address issues
    concerning Native Hawaiians, setting aside area within the HO
    site solely for use by Native Hawaiians, removing unused
    facilities, and decommissioning the ATST within 50 years.
    Other mitigating effects included the expected
    scientific, economic, and educational benefits of the ATST.                 BLNR
    determined that the ATST would result in “the advancement of
    scientific knowledge,” as it would “significantly increase
    understanding of the Sun . . . and help scientists predict major
    solar events having a profound impact on life on Earth.”
    Additionally, BLNR noted that “[j]obs and revenue for the economy
    would be created on Maui,” including job opportunities in the
    “clean high-tech industry.”       It also concluded that
    “[e]ducational opportunities would be created for students at the
    Maui Community College as well as for native Hawaiian
    astronomers” to “foster a better understanding of the
    relationships between native Hawaiian culture and science.”21
    21
    Specifically, Maui College submitted a “mitigation proposal,”
    which requested funding for:
    (1) development and implementation of an innovative
    math and science curriculum and program based on
    Hawaiian cultural knowledge and worldview; (2)
    building up relevant coursework and dedicated programs
    at Maui College; (3) significantly increasing the
    number and retention of native Hawaiian students in
    (continued...)
    48
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    Additionally, BLNR noted that the ATST was designed to
    be as small as possible while still being consistent with
    scientific needs.         It also added permit conditions that would
    mitigate impacts on cultural resources, including:
    17. Within 2 years of completion of the construction
    of the ATST facility, Kilakila may require the
    construction and consecration of a new ahu[22] in
    addition to the two currently present. Upon request
    by Kilakila, UHIfA will work with Kilakila, the
    Cultural Specialist and the Native Hawaiian Working
    Group to select an appropriate location for the new
    ahu which shall be built and consecrated in [a]
    similar manner to the prior ahu;
    . . . .
    20. In order to protect the traditional and customary
    rights exercised in the HO site, during construction
    of the ATST Project and after, UHIfA shall allow
    access to the two ahu for the reasonable exercise of
    traditional and customary practices of native
    Hawaiians to the extent feasible and safe, as
    determined by the Cultural Specialist and the ATST
    Project construction site supervisor.
    Based on this analysis, BLNR concluded that “[t]he
    proposed land use, when considered together with all minimization
    and mitigation commitments discussed . . . and with the
    additional conditions contained in this Decision, will not cause
    21
    (...continued)
    Science, Technology, Engineering and Math (“STEM”)
    courses and programs at Maui College; and (4)
    cultivating and developing an experienced, highly
    skilled native Hawaiian workforce for STEM related
    industries and careers.
    The National Science Foundation adopted the proposal and “will make $20
    million ($2 million per fiscal year for ten years) available to support this
    educational initiative to address the intersection between traditional native
    Hawaiian culture and science and to foster a better understanding of the
    relationships between native Hawaiian culture and science.”
    22
    An “ahu” is defined as an altar or shrine. Pukui & Elbert,
    Hawaiian Dictionary 8 (2nd ed. 1986). In 2005, UHIfA contracted with Native
    Hawaiian stonemasons to erect a west-facing ahu within the HO site. In 2006,
    “in the spirit of makana aloha for the ATST Project,” UHIfA contracted with
    the same stonemasons to erect an east-facing ahu in the HO site.
    49
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    substantial adverse impact [sic] to existing natural resources
    within the surrounding area, community or region.”
    In reviewing BLNR’s findings under HAR § 13-5-30(c)(4),
    we first consider BLNR’s reliance on the “incremental” nature of
    the ATST Project.    We agree with Kilakila that BLNR does not have
    license to endlessly approve permits for construction in
    conservation districts, based purely on the rationale that every
    additional facility is purely incremental.         It cannot be the case
    that the presence of one facility necessarily renders all
    additional facilities as an “incremental” addition.
    In spite of our concerns, we are not “left with a firm
    and definite conviction” that BLNR made a mistake in reaching its
    conclusion given the highly specific circumstances of this case.
    Brescia v. N. Shore Ohana, 115 Hawai#i 477, 491-92, 
    168 P.3d 929
    ,
    943-44 (2007) (“An agency’s findings are not clearly erroneous
    and will be upheld if supported by reliable, probative and
    substantive evidence unless the reviewing court is left with a
    firm and definite conviction that a mistake has been made.”)
    (quoting Poe v. Hawai#i Labor Relations Bd., 105 Hawai#i 97, 100,
    
    94 P.3d 652
    , 655 (2004)).
    BLNR reviewed the ATST Project within the context of a
    single, highly developed 18.166-acre area within a much larger
    conservation district, and which involves a use (astromony) which
    is specifically permitted in the general subzone of the
    50
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    conservation district.     The FEIS also determined that the level
    of impacts on natural resources would be substantially the same
    even in the absence of the ATST.         In addition, UHIfA committed to
    mitigation measures directed at reducing the cultural and visual
    impacts on natural resources.       See HAR § 13-5-42(a)(9) (1994)
    (“All representations relative to mitigation set forth in the
    accepted environmental assessment or impact statement for the
    proposed use are incorporated as conditions of the permit[.]”);
    see also Morimoto v. Bd. of Land & Nat. Res., 107 Hawai#i 296,
    303, 
    113 P.3d 172
    , 179 (2005) (concluding that BLNR properly
    considered mitigation measures when evaluating HAR §
    13-5-30(c)(4)).    Taken cumulatively, BLNR “articulate[d] its
    factual analysis with reasonable clarity” why the ATST would not
    result in a substantial adverse impact on natural resources.
    Waiâhole, 94 Hawai#i at 
    164, 9 P.3d at 476
    .
    Lastly, Kilkila argues that BLNR made its findings
    under HAR § 13-5-30(c) based on “unwritten criteria,” referring
    to BLNR’s mention of the ATST’s scientific, economic, and
    educational benefits in its findings under HAR § 13-5-30(c)(4).
    However, there is no regulation suggesting that BLNR could not
    consider benefits related to HAR § 13-5-30(c) when approving a
    permit.   HAR § 13-5-30(c) states, “In evaluating the merits of a
    proposed land use, the department or board shall apply the
    following criteria[,]” but the statute and agency regulations
    51
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    concerning conservation districts do not suggest that scientific,
    economic, and education benefits are not relevant.            Rather, they
    suggest the opposite.
    The purpose of HAR § 13-5-30(c) and the other
    conservation district regulations is “to regulate land-use in the
    conservation district for the purpose of conserving, protecting,
    and preserving the important natural and cultural resources of
    the State through appropriate management and use to promote their
    long-term sustainability and the public health, safety, and
    welfare.”    HAR § 13-5-1 (1994).      The statute governing the
    conservation districts, HRS § 183C-1 (Supp. 1996), similarly
    states:
    The legislature finds that lands within the
    state land use conservation district contain important
    natural resources essential to the preservation of the
    State’s fragile natural ecosystems and the
    sustainability of the State’s water supply. It is
    therefore, the intent of the legislature to conserve,
    protect, and preserve the important natural resources
    of the State through appropriate management and use to
    promote their long-term sustainability and the public
    health, safety and welfare.
    BLNR is therefore unequivocally tasked with protecting
    natural and cultural resources through “appropriate management
    and use to promote their long-term sustainability and the public
    health, safety, and welfare.”        HRS § 183C-1; HAR § 13-5-1.       The
    consideration of relevant scientific, economic, and educational
    benefits of the ATST within the context of the HO does not
    conflict with this, as these benefits impact long-term
    52
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    sustainability and public welfare.23        See Black’s Law Dictionary
    1828 (10th ed. 2014) (defining “public welfare” as “[a] society’s
    well-being in matters of health, safety, order, morality,
    economics, and politics”).
    The cases cited by Kilakila are not applicable here,
    where an agency has evaluated considerations relevant to––rather
    than instead of––the criteria set forth in the applicable
    regulations.    See Aluli v. Lewin, 
    73 Haw. 56
    , 58, 
    828 P.2d 802
    ,
    803 (1992) (agency had no rules governing the issuance of
    permit); Mahuiki v. Planning Comm’n, 
    65 Haw. 506
    , 519, 
    654 P.2d 874
    , 882 (1982) (court found no evidence in the record supporting
    agency finding); Ainoa v. Unemployment Compensation Appeals Div.,
    
    62 Haw. 286
    , 293, 
    614 P.2d 380
    , 385 (1980) (agency failed to
    comply with existing requirements); Aguiar v. Hawai#i Hous.
    Auth., 
    55 Haw. 478
    , 498, 
    522 P.2d 1255
    , 1268 (1974) (same).
    Therefore, while BLNR could certainly not rely solely
    on the scientific, economic, or educational benefits of the ATST,
    BLNR did not improperly consider benefits relevant to the ATST’s
    23
    We agree with Kilakila that BLNR should not have considered that
    “[j]obs and revenue for the economy would be created on Maui” under
    13-5-30(c)(4) inasmuch as jobs unrelated to the preservation and advancement
    of natural or cultural resources are irrelevant.   However, as BLNR properly
    considered the scientific and educational benefits in addition to the findings
    in the FEIS and numerous other mitigating measures, we conclude that this
    error was harmless. See Korean Buddhist Dae Won Sa Temple, 87 Hawai#i at 241-
    
    42, 953 P.2d at 1339-40
    (holding that the Director of the Department of Land
    Utilization’s improper consultation of evidence outside the record was
    harmless error because “the outcome of the proceedings would not have been
    altered”).
    53
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    expected impact on existing natural resources under HAR §
    13-5-30(c)(4).    See Morimoto, 107 Hawai#i at 
    303, 113 P.3d at 179
    (allowing BLNR to consider mitigation measures even though not
    explicitly mentioned in HAR § 13-5-30(c)).
    Accordingly, we find that BLNR’s conclusion that the
    ATST satisfied the criteria under HAR § 13-5-30(c)(4) was not
    clearly erroneous, though we emphasize that review of future BLNR
    decisions will be “dependent upon the facts and circumstances of
    the particular case.”     Save Diamond Head Waters, 121 Hawai#i at

    499, 146 P.3d at 1076
    ).
    2.   BLNR did not err in interpreting HAR § 13-5-30(c)(5) to
    include the area within the HO
    HAR § 13-5-30(c)(5) states:        “The proposed land use,
    including buildings, structures, and facilities, shall be
    compatible with the locality and surrounding areas, appropriate
    to the physical conditions and capabilities of the specific
    parcel or parcels[.]”     Kilakila argues that the ICA erred in
    affirming BLNR’s interpretation of “locality and surrounding
    areas” in HAR § 13-5-30(c)(5) as the immediate vicinity of the
    proposed ATST site.     Rather, Kilakila asserts that “surrounding
    areas” includes Haleakalâ National Park, and that there is no
    evidence that the ATST is compatible with the Park.
    In its consideration of HAR § 13-5-30(c)(5), BLNR
    54
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    focused on the permitted land use in the HO site:
    The HO site was specifically set aside for observatory
    site purposes under Executive Order No. 1987.
    Astronomical and observatory facilities have existed
    on the HO site since 1951. The ATST Project includes
    the construction of astronomical facilities which are
    compatible with the locality and surrounding areas,
    appropriate to the physical conditions and
    capabilities of the specific parcel.
    Because it did not mention areas outside of the HO
    site, BLNR necessarily interpreted “locality and surrounding
    areas” as the areas within the HO site.
    We defer to BLNR’s interpretation unless it was plainly
    erroneous or inconsistent with the underlying legislative
    purpose.   See Kaleikini v. Yoshioka, 128 Hawai#i 53, 67, 
    283 P.3d 60
    , 74 (2012) (“An agency’s interpretation of its own rules is
    generally entitled to deference.”); In re Wai#ola O Moloka#i,
    Inc., 103 Hawai#i 401, 425, 
    83 P.3d 664
    , 688 (2004) (stating that
    courts do not defer to agency interpretations that are “plainly
    erroneous or inconsistent with the underlying legislative
    purpose”).
    The ATST will be located in a small subsection of the
    HO site, which is a clearly defined, highly specialized area.
    The HO site’s 18.166 acres were specifically set aside for
    observatory site purposes by Governor Quinn in 1961, and this
    site is the only site at Haleakalâ used for these purposes.
    Since Governor Quinn’s designation, the HO has been considerably
    developed by the construction of numerous observatories and other
    55
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    astronomical research facilities.        The ATST will be the next
    facility built within the site’s set boundaries and will fulfill
    the site’s designated purposes.       As such, it was not plainly
    erroneous to interpret “locality” as the location of the ATST and
    “surrounding areas” as the HO site, due to the site’s unique
    characteristics and history.
    Kilakila argues that BLNR recognized that Haleakalâ
    National Park was part of the “surrounding area” based on a quote
    from the BLNR order approving the permit.         In describing a site
    visit, BLNR states:
    The parties and Hearing Officer Jacobson visited the
    site of the proposed ATST and the surrounding area on
    July 15, 2011. They observed the views from the area,
    the proximity of the structures to each other, the ahu
    in the HO site and views from them, the view from Pu#u
    #Ula#ula, the view from Haleakalâ National Park Visitor
    Center and the area around the Visitor Center, the
    view from the road driving up to the HO site, and the
    historic sites in the HO site.
    This quote does not demonstrate any such recognition,
    as the second sentence appears to simply be listing locations
    without any reference to the first sentence’s use of “surrounding
    area.”   Regardless, the fact that BLNR used the term “surrounding
    area” in describing a site visit does not bind BLNR to this exact
    definition when interpreting HAR § 13-5-30(c)(5).
    Therefore, the ICA did not err in affirming BLNR’s
    conclusions under HAR § 13-5-30(c)(5).
    56

    3.   BLNR did not err in concluding existing aspects of the
    land would be preserved under HAR § 13-5-30(c)(6)
    HAR § 13-5-30(c)(6) states:        “The existing physical and
    environmental aspects of the land, such as natural beauty and
    open space characteristics, will be preserved or improved upon,
    whichever is applicable[.]”      Kilakila argues that HAR §
    13-5-30(c)(6) is not satisfied because UH admitted that the ATST
    does not improve natural beauty or open space characteristics,
    and because “BLNR failed to point to any evidence that ATST
    preserves natural beauty and open space[.]”
    In its consideration of HAR § 13-5-30(c)(6), BLNR noted
    that “[t]he ATST will not enhance the natural beauty or open
    space characteristics of the HO site.”         However, because “[t]he
    HO site contains various astronomy facilities, including support
    buildings, roads and parking lots[,]” and “the proposed ATST is
    similar to existing facilities,” BLNR concluded that “[t]he ATST
    will be consistent with and will preserve the existing physical
    and environmental aspects of the land.”         In other words, BLNR
    relied on similar reasoning as in HAR § 13-5-30(c)(4), which
    focused on the ATST within the context of the HO site.            Because
    the ATST will be located within the HO site and among other
    pre-existing facilities, the ATST will maintain, or “preserve,”
    the “existing physical and environmental aspects of the land[.]”
    Additionally, BLNR considered numerous mitigation
    57
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    commitments in the CDUA, which were designed to mitigate impacts
    on biological resources.        The measures included consulting a
    wildlife biologist, monitoring invertebrates, flora, and fauna,
    and following washing and inspection protocol to prevent the
    introduction of alien invasive species.           BLNR also determined
    that “[l]ittle to no impacts are anticipated to the topography,
    geology, soils, water resources or air quality as a result of the
    ATST Project and as such no mitigation is required.”
    Therefore, similar to its analysis of HAR
    § 13-5-30(c)(4), BLNR articulated with “reasonable clarity” why
    the ATST would preserve the existing physical and environmental
    aspects of the land.       See Waiâhole, 94 Hawai#i 97 at 
    164, 9 P.3d at 476
    .    Because we are not “left with a firm and definite
    conviction that a mistake has been made,” we do not find BLNR’s
    findings regarding HAR § 13-5-30(c)(6) clearly erroneous, and we
    affirm the ICA on this point.         Brescia, 115 Hawai#i at 
    492, 168 P.3d at 944
    .
    C.    The ATST is not Inconsistent with the Purposes of
    Conservation Districts and General Subzones
    Kilakila argues that the ICA erred in determining that
    the ATST is consistent with the purposes of the conservation
    district because of its “unprecedented height, mass, and scale;
    industrial appearance; use of hazardous materials, location in
    ‘Science City’, location in an area that is already 40%
    58
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    developed, and substantial impacts[.]”         The issue presents a
    mixed question of fact and law, and is therefore “reviewed under
    the clearly erroneous standard because the conclusion is
    dependent upon the facts and circumstances of the particular
    case.”   Save Diamond Head Waters, 121 Hawai#i at 
    25, 211 P.3d at 83
    (quoting Del Monte Fresh Produce, 112 Hawai#i at 
    499, 146 P.3d at 1076
    ).
    To grant a CDUP in a conservation district, HAR
    § 13-5-30(c)(1) requires that the proposed land use is
    “consistent with the purpose of the conservation district[.]”
    Additionally, HAR § 13-5-30(c)(2) requires that the proposed land
    use must be “consistent with the objectives of the subzone of the
    land on which the use will occur[.]”        The ATST must therefore be
    consistent with the purposes of general subzones and conservation
    districts.
    A general subzone seeks to “designate open space where
    specific conservation uses may not be defined, but where urban
    use would be premature.”      HAR § 13-5-14(a).      HAR § 13-5-24
    together with HAR § 13-5-25 provide guidance on appropriate land
    uses in general subzones.      HAR § 13-5-24 lists “astronomy
    facilities under an approved management plan” as one of the
    allowable uses under a resource subzone.         HAR § 13-5-25 states
    that “[i]n addition to the land uses identified [for general
    subzones], all identified land uses . . . for the . . . resource
    59
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    subzones also apply to the general subzone, unless otherwise
    noted.”   Together, these rules specifically permit the
    construction of astronomy facilities and do not specify a limit
    as to size, appearance, or other characteristics.           As an
    astronomy facility, the ATST falls under an appropriate use and
    is not inconsistent with the purposes of a general subzone.
    Additionally, as discussed above, the ATST complies
    with the broad purposes set out in the statute and agency rules
    regulating conservation districts.        See HAR § 13-5-1 (directing
    BLNR to manage natural and cultural resources “to promote their
    long-term sustainability and the public health, safety, and
    welfare”); HRS § 183C-1 (stating that the legislature created
    conservation districts “to conserve, protect, and preserve the
    important natural resources of the State through appropriate
    management and use to promote their long-term sustainability and
    the public health, safety and welfare”).
    In sum, BLNR did not erroneously conclude that the ATST
    was consistent with the purposes of both general subzones and
    conservation districts.
    IV.   Conclusion
    For the reasons stated above, BLNR properly granted
    CDUP MA-11-04 for construction of the ATST.          The permit did not
    suffer from the procedural infirmities of prejudgment or improper
    ex parte communications, BLNR made valid findings under the
    60
    *** FOR PUBLICATION IN WEST’S HAWAI#I REPORTS AND PACIFIC REPORTER ***
    applicable permit criteria, and the ATST is not inconsistent with
    the purposes of the conservation district.         Therefore, the ICA’s
    November 13, 2014 Judgment on Appeal is affirmed.
