    Clerk
    Justice Brian Morris delivered the Opinion of the Court.
    ¶1     Bostwick Properties, Inc. (Bostwick) sought a water use permit from the Montana
    Department of Natural Resources and Conservation (DNRC). DNRC denied the water use
    permit. Bostwick petitioned for review by the District Court. The District Court agreed with
    DNRC that Bostwick had failed to prove no net depletion of surface water and lack of
    adverse effect, as required by § 85-2-360, MCA, and therefore Bostwick was required to
    mitigate its water usage in order to receive a water use permit. The District Court further
    determined, however, that Bostwick had submitted an adequate mitigation proposal, and,
    therefore, DNRC improperly had denied Bostwick’s permit application. The District Court
    further noted that DNRC had exhibited bias against Bostwick. The District Court separately
    affirmed each of DNRC’s findings, and so determined that any bias on the part of DNRC
    caused no prejudice to Bostwick. Bostwick appeals, DNRC cross-appeals, and we affirm.
    ¶2     Bostwick and DNRC present the following issues on appeal:
    ¶3     Whether DNRC had authority to deny Bostwick’s permit?
    ¶4     Whether DNRC and the District Court properly required Bostwick to mitigate its
    water usage?
    ¶5     Whether the District Court properly determined Bostwick’s mitigation proposal was
    adequate as a matter of law?
    ¶6     Whether DNRC had the authority to require Bostwick to identify a specific water right
    for mitigation?
    ¶7     Whether DNRC bias substantially prejudiced Bostwick?
    2
    PROCEDURAL AND FACTUAL BACKGROUND
    ¶8     Bostwick filed an application for a Beneficial Water Use Permit with DNRC on
    December 1, 2006. Bostwick sought the water use permit for municipal use in its Lazy J
    South subdivision in Gallatin County, Montana. Bostwick initially sought up to 79 acre-feet
    per year of groundwater year round. Bostwick sought to extract this groundwater from an
    aquifer. DNRC designated Bostwick’s water use permit application “correct and complete”
    on February 12, 2007, and noticed the application to the public. Montana Department of
    Fish, Wildlife, and Parks (FWP) and Montana Trout Unlimited (TU) objected to Bostwick’s
    application. Both objectors later withdrew their objections provided that Bostwick reduced
    its water use to 76 acre-feet per year.
    ¶9     DNRC failed to take action on Bostwick’s application within the timeframe set forth
    in § 85-2-310(1), MCA. Bostwick sought a writ of mandate to require DNRC to issue the
    water use permit, or, alternatively, to hold a hearing to force DNRC to show cause why
    DNRC would not grant the permit. After Bostwick sought the writ of mandate, DNRC
    issued a statement of opinion that denied Bostwick’s water use permit. DNRC determined
    that Bostwick had failed to demonstrate no net depletion of surface water, as required by §
    85-2-360, MCA, and had failed to prove legal availability and lack of adverse impact, as
    required by § 85-2-311, MCA. DNRC determined that Bostwick had demonstrated the other
    criteria required by § 85-2-311, MCA.
    ¶10    The District Court granted Bostwick’s request for a writ of mandate. DNRC appealed
    to this Court. Bostwick Props. v. Mont. Dep’t of Nat. Res. & Conserv., 
    2009 MT 181
    , 351
    
    3 Mont. 26
    , 
    208 P.3d 868
     (Bostwick I). We reversed the District Court’s grant of the writ of
    mandate. We determined that DNRC had no legal duty to grant Bostwick’s permit
    application because Bostwick had not yet proven lack of adverse effect and legal availability.
    Bostwick I, ¶ 21. We remanded the case to DNRC with instructions to provide Bostwick
    with an opportunity to be heard on its water use permit application. Bostwick I, ¶ 23.
    Bostwick requested that DNRC disqualify itself to hear Bostwick’s application on the
    grounds of bias. DNRC denied Bostwick’s request for disqualification.
    ¶11    The Gallatin River is part of a closed water basin. Sections 85-2-342 to 85-2-343,
    MCA.     In order to receive a groundwater permit, Bostwick first had to provide a
    hydrogeologic assessment to determine whether its proposed groundwater usage would result
    in a net depletion of surface water. Section 85-2-360, MCA. Bostwick would have to
    mitigate its water usage if Bostwick’s proposed pumping of groundwater would result in a
    net depletion of surface water and adversely affect senior appropriators. Section 85-2-362,
    MCA.
    ¶12    Bostwick offered alternatives to demonstrate that its groundwater use would not result
    in a net depletion of the Gallatin River surface water, or would not cause an adverse effect.
    Bostwick first proposed that its Pave and Infiltrate Plan would offset all proposed
    consumption and would result in no net depletion of surface water. Bostwick next proposed
    that no net depletion would occur because the hydrological connection between the aquifer
    and the surface water was too attenuated and any potential adverse effect was unknown.
    Bostwick argued that the amount of water that it sought was too small to result in an adverse
    4
    effect. Bostwick also suggested that DNRC could terminate Bostwick’s water rights if
    Bostwick’s de minimus water usage actually harmed senior rights holders. Bostwick finally
    proposed mitigation in the form of purchasing Water Right No. 41H 226700, in the event
    that Bostwick failed to demonstrate no net depletion or lack of adverse effect.
    ¶13     DNRC determined that Bostwick’s water use would result in a net depletion of
    surface water, and that Bostwick had failed to demonstrate lack of adverse effect. This
    determination required Bostwick to mitigate its proposed water use. DNRC further
    determined that Bostwick’s proposed mitigation, purchasing Water Right No. 41H 226700,
    was inadequate because the mitigation would provide only irrigation season water and would
    provide no non-irrigation season water. DNRC’s determinations that Bostwick had failed to
    demonstrate no net decrease and had failed to demonstrate a lack of adverse effect for non-
    irrigation season water required Bostwick to mitigate non-irrigation season water loss as
    well.
    ¶14     Bostwick sought review by the District Court. The district court agreed with DNRC
    that Bostwick had failed to demonstrate no net depletion and lack of adverse effect. The
    District Court deemed adequate as a matter of law, however, Bostwick’s mitigation proposal.
    The District Court determined that DNRC improperly had denied Bostwick’s water use
    permit subject to implementation of Bostwick’s mitigation plan. Bostwick appeals the
    District Court’s determination that Bostwick failed to demonstrate no net depletion or lack of
    adverse effect. DNRC cross-appeals on the grounds that Bostwick’s mitigation proposal did
    not mitigate non-irrigation season water use.

    STANDARD OF REVIEW
    ¶15    We review for correctness a district court’s review of an administrative agency’s
    decision. BNSF Ry. Co. v. Cringle, 
    2010 MT 290
    , ¶ 11, 
    359 Mont. 20
    , 
    247 P.3d 706
    . We
    review for correctness a district court’s conclusions of law. Cringle, ¶ 11.
    DISCUSSION
    ¶16    Whether DNRC had authority to deny Bostwick’s permit?
    ¶17    Bostwick argues that its settlement with all objectors required DNRC as a matter of
    law to grant Bostwick a water use permit. DNRC instead issued a statement of opinion that
    provided that Bostwick had failed to show no net decrease, pursuant to § 85-2-360, MCA,
    and to show legal availability and lack of adverse effect pursuant to § 85-2-311(1), MCA.
    Bostwick argues that DNRC’s previous determination that Bostwick’s application was
    “correct and complete” deprived DNRC of any further authority to issue a statement of
    opinion or to deny the permit after Bostwick settled with the objectors.
    ¶18    We considered and rejected this argument in Bostwick I. The District Court in
    Bostwick I concluded that DNRC was required, as a matter of law, to grant Bostwick’s
    permit because DNRC had determined Bostwick’s application was “correct and complete,”
    and all objections had been resolved. Bostwick I, ¶ 20. DNRC must grant a permit only if
    Bostwick resolved the objections and Bostwick proved the § 85-2-311, MCA, criteria by a
    preponderance of the evidence. Bostwick I, ¶ 21. Bostwick was required to prove legal
    availability and lack of adverse effect by a preponderance of the evidence. Bostwick I, ¶ 21.
    6
    DNRC had legal authority, and the legal duty, to deny Bostwick’s permit if Bostwick failed
    to do so. Bostwick I, ¶ 21.
    ¶19    Whether DNRC and the District Court properly required Bostwick to mitigate its
    water usage?
    ¶20    Bostwick offers four theories to support its argument that its water use would result in
    no net depletion of surface water or would not adversely affect senior appropriators. We
    analyze each in turn.
    1. Bostwick’s Pave & Infiltrate Plan
    ¶21    Bostwick first argues that its Pave and Infiltrate Plan would offset any net depletion of
    surface water from its proposed pumping of groundwater. Bostwick plans to pave roads and
    parking lots in its proposed development. Bostwick contends that precipitation that
    previously had evaporated or had been used by native plants would run off these new
    impermeable surfaces. Bostwick would store this runoff water in retention ponds. Bostwick
    would discharge this runoff water from the retention ponds into the groundwater, which in
    turn eventually would recharge the Gallatin River. Bostwick estimated that it would collect
    42 acre-feet per year of runoff water. This “savings” represents more than the 39 acre-feet
    per year that Bostwick seeks to deplete with its water use permit. Bostwick argues, as a
    result, that its development as a whole would cause no net decrease in surface water and no
    adverse effect.
    ¶22    Section 85-2-361(1), MCA, lists factors that DNRC should consider in predicting
    whether a water appropriation would result in a net depletion of surface water. These factors
    7
    include the actual amount diverted, the amount likely to be lost in conveyance, any return
    due to percolation, and any return flows such as wastewater. Section 85-2-361(1), MCA,
    further provides that these factors do not constitute an exhaustive list of criteria to consider
    when it evaluates net depletion of surface water. Bostwick argues that DNRC should
    consider the runoff caused by Bostwick’s proposed development in this calculation of
    potential depletion of surface water. Bostwick provides no legal support to include its runoff
    water in the surface water depletion calculation.
    ¶23    We look at four factors when we interpret a statute. First, we ask whether the
    interpretation reflects the intent of the legislature considering the plain language of the
    statute. U.S. West, Inc. v. Dep’t of Revenue, 
    2008 MT 125
    , ¶ 16, 
    343 Mont. 1
    , 
    183 P.3d 16
    .
    We next examine whether the interpretation comports with the statute as a whole. U.S. West,
    ¶ 16. We then consider whether an agency charged with administration of the statute has
    placed a construction on the statute. U.S. West, ¶ 16. Finally, where appropriate, we analyze
    whether the interpretation avoids absurd results. U.S. West, ¶ 16.
    ¶24    The plain language of § 85-2-361(1), MCA, indicates that Bostwick’s interpretation of
    this statute fails to reflect the intentions of the legislature. The legislature listed only factors
    that concern the appropriated water. The analysis of the “actual amount diverted” and the
    “amounts that will likely be lost in conveyance” considers only the appropriated water.
    Similarly, the “return flow” analysis contemplates how much of the appropriated water will
    “return.” None of these factors requires DNRC to consider sources of water other than the
    proposed water to be appropriated pursuant to Bostwick’s permit. Nothing indicates, based
    8
    on the plain language of the statute, that the legislature intended DNRC to consider
    alternative sources of water, such as Bostwick’s runoff, when it calculates net-depletion.
    ¶25    Bostwick’s interpretation also conflicts with the statute as a whole. The legislature
    separately considered the role of sources of water other than the appropriated water. The
    legislature labeled this other water as “mitigation” water. Sections 85-2-102(15), 85-2-360
    to 85-2-363, MCA. If a water allocation would result in a net depletion of surface water, the
    statute requires the applicant to submit a mitigation plan that would introduce a new source
    of water to offset any adverse effect caused by the net depletion of surface water. Section
    85-2-360, MCA. The legislature clearly has directed DNRC to evaluate water other than the
    appropriated water as potential mitigation. It would be contrary to the statutory scheme to
    require DNRC instead to consider this runoff water in its net-depletion calculation.
    ¶26    Bostwick does not argue that it can use this runoff water as mitigation, and, indeed, it
    could not. The legislature defined mitigation as the “reallocation of surface water or ground
    water through a change in appropriation right.” Section 85-2-102(15), MCA. Bostwick
    currently has no appropriation right to use this runoff water. The legislature clearly stated
    that a water use permit represents the sole way to appropriate water. Sections 85-2-301 to
    85-2-302, MCA. Bostwick could not use this runoff water as mitigation water.
    ¶27    The agency charged with administering this statute, DNRC, concluded that it should
    not consider Bostwick’s runoff water when it calculated net depletion. Bostwick did not
    argue specifically that this statute, § 85-2-361, MCA, or any legal authority, requires DNRC
    to consider Bostwick’s runoff water as part of the net-depletion calculation. DNRC
    9
    concluded that no legal authority supported Bostwick’s claim that DNRC should consider
    Bostwick’s runoff as part of DNRC’s net-depletion calculation.
    ¶28    As noted above, Bostwick has no legal right to appropriate this runoff water. A water
    use permit represents the sole way Bostwick could acquire an appropriation right. Sections
    85-2-301 to 85-2-302, MCA. An anomalous result would occur if Bostwick could use this
    runoff water in its net-depletion of surface water calculation even though Bostwick has no
    legal right to appropriate this runoff water.
    ¶29    Finally, the legislature has moved away from the old-fashioned understanding of
    water appropriation that underpins Bostwick’s claim that it can use this runoff water in the
    net-depletion analysis. This Court previously recognized the notion of “developing” water
    by tapping an underground aquifer or by bringing water to a location it otherwise would not
    have reached. See State ex. rel. Mungas v. Dist. Ct., 
    102 Mont. 533
    , 
    59 P.2d 71
     (1936); Rock
    Creek Ditch & Flume Co. v. Miller, 
    93 Mont. 248
    , 
    17 P.2d 1074
     (1933). Bostwick
    essentially argues that it would be “developing” water by capturing runoff water.
    Historically, a party who “developed” water could appropriate that water ahead of senior
    appropriators. The legislature rejected the notion that a person could appropriate water by
    “developing” it. The legislature instead declared that starting in 1973, a water use permit
    represented the sole way to appropriate water. See §§ 85-2-301 to 85-2-302, MCA. This
    new law superseded our old cases, including Mungas and Rock Creek, regarding the ability
    of a party to appropriate water through the “development” of water. See §§ 85-2-301 to 85-
    2-302, MCA.
    10
    ¶30    The legislature has adopted a system that recognizes the hydrological cycle and the
    adverse effect that new appropriations of surface water or ground water could cause to senior
    appropriators. The legislature specifically recognized that depletion of groundwater could
    cause a depletion of surface water. See § 85-2-360, MCA. The legislature now requires
    water use permit applicants to demonstrate that their groundwater usage in a closed basin
    will not adversely affect senior appropriators of surface water. Sections 85-2-360, 85-2-363,
    MCA. Bostwick’s capture of surface water similarly could cause a depletion in the surface
    water or groundwater in the closed Gallatin River Basin that could adversely affect senior
    appropriators. The legislature’s recent modifications to Montana water law confirm that the
    legislature did not intend to allow Bostwick to use an additional source of water, such as the
    runoff water, in the net-depletion of surface water calculation. See §§ 85-2-301 to 85-2-302,
    MCA.
    ¶31    Nothing in § 85-2-361, MCA, supports Bostwick’s interpretation that DNRC should
    consider the runoff water caused by Bostwick’s pavement when DNRC calculates the net
    depletion caused by Bostwick’s water allocation. This interpretation would run contrary to
    the plain meaning of the statute, to the statutory scheme as a whole, to the DNRC’s
    interpretation, and would cause an absurd result whereby Bostwick could claim the runoff
    water in the net-depletion calculation even though Bostwick would have no legal right to use
    the water. See U.S. West, ¶ 16.
    2. Attenuated Hydrological Connection
    11
    ¶32    Bostwick next argues that the attenuated hydrological connection between the source
    ground water and the surface water would cause no net depletion of surface water in the
    Gallatin River. Bostwick argues that the lack of net depletion of surface water related to its
    water extraction would not adversely affect senior appropriators. Bostwick admits that the
    groundwater that Bostwick seeks to extract from the aquifer ultimately would have ended up
    in the Gallatin River. Bostwick argues, however, that no way exists to determine at what
    point the Gallatin River would begin to lose water due to Bostwick’s extraction of water
    from the aquifer. Bostwick argues that this uncertainty confirms that no net depletion, or no
    adverse effect, could be shown.
    ¶33    Bostwick points to a recent DNRC permit for new groundwater use by Yellowstone
    Club, In the Matter of the Application for Beneficial Water Use Permit 41H-30027281, as
    evidence that DNRC should grant the water use permit when an unknown connection exists
    between an aquifer and surface water. Yellowstone Club sought a water use permit several
    miles from Bostwick’s proposed development. Yellowstone Club failed to demonstrate
    where or how its depletion from the aquifer would affect the Gallatin River. DNRC
    nevertheless granted the Yellowstone Club’s water use permit because no practical way
    existed to establish how or when the groundwater would affect the surface water. Bostwick
    argues that DNRC should have applied this same principle to Bostwick’s water use permit.
    ¶34    DNRC ultimately conceded to the District Court that it wrongly had granted the water
    use permit to Yellowstone Club. The District Court determined that DNRC’s issuance of a
    water use permit to the Yellowstone Club did not establish any binding precedent that would
    12
    force DNRC to issue Bostwick’s permit under similar circumstances. The District Court
    further determined that past DNRC cases and Montana law support DNRC’s decision to
    deny a permit where uncertainty exists regarding any hydrological connection.
    ¶35    We agree. This Court possesses authority to reverse any arbitrary and capricious
    agency decision. Section 2-4-704, MCA. We may reverse an arbitrary and capricious
    decision of an agency, even if the agency follows its own prior arbitrary and capricious
    decision. DNRC correctly applied the permit criteria for Bostwick’s permit application
    despite DNRC’s failure to follow the same analysis in reviewing the Yellowstone Club’s
    permit application.
    ¶36    Bostwick admits that some hydrological connection exists between the groundwater
    from the aquifer and the Gallatin River. Bostwick argues it is unknown exactly when
    Bostwick’s extraction of groundwater would affect the Gallatin River. Bostwick seeks to
    shift the burden of proof to DNRC, however, and thereby require DNRC to grant the permit
    if no net depletion, and so no adverse effect, could be shown. Section 85-2-311(1)(a)(ii),
    MCA, clearly places the burden of proof on the applicant to demonstrate lack of adverse
    effect. Bostwick bears the burden of demonstrating that its efforts to pump water from the
    aquifer would cause no adverse effect on prior appropriators of the Gallatin River. Bostwick
    admits that it could not establish the effect of this proposed pumping on prior appropriators.
    The District Court correctly determined that Bostwick had failed to prove lack of any
    adverse effect.
    3. De Minimus Water Usage
    13
    ¶37    Bostwick next argues that the de minimus amount of water that it would deplete from
    the Gallatin River could not adversely affect senior water rights holders. Boswick seeks to
    deplete 24.1 gallons per minute. Bostwick notes that this 24.1 gallons per minute constitutes
    0.035% of the lowest recorded flow on the Gallatin River. Bostwick contends that § 85-2-
    360(5), MCA, supports an exception for its de minimus water usage. Bostwick recognizes
    that its permit application predated this legislative amendment for de minimus usage.
    Bostwick argues that the legislature merely confirmed the law that already existed.
    ¶38    Section 85-2-360(5), MCA, provides that the prediction of a net depletion does not
    automatically mean that an adverse effect would occur. DNRC must determine whether an
    adverse effect exists “based on the amount, location, and duration” of the depletion “relative
    to the historic beneficial use.” Section 85-2-360(5), MCA. This language creates no de
    minimus exception. It simply restates the principle that a depletion would not adversely
    affect any prior appropriators if sufficient water exists. Alternatively, the amendment
    acknowledges that if an adverse effect occurs, the amount of the adverse effect would not
    necessarily represent the full amount of the depletion. Further, the amended version of the
    statute still imposes on Bostwick the burden of proof to demonstrate lack of any adverse
    effect. Section 85-2-311, MCA.
    ¶39    DNRC correctly determined that Bostwick failed to prove lack of adverse effect, even
    for Bostwick’s minimal 39 acre-feet per year water depletion. No legally available water
    exists on the Gallatin River during the irrigation season. The Gallatin Water Commissioner
    generally cuts off water rights each irrigation season for priority dates later than 1890. In
    14
    fact, in 2012, the Water Commissioner cut off water rights owners junior to 1883. Any
    additional depletion of water, even one as minimal as 39 acre-feet per year, potentially would
    adversely affect senior appropriators’ water rights.
    4. Administration of Priorities
    ¶40       Bostwick further argues that any adversely affected senior rights holders on the
    Gallatin River could force Bostwick to stop using water through the administration of
    priorities. Bostwick would ask this Court to shift the burden of proving lack of adverse
    effect and require prior appropriators to prove that Bostwick caused an adverse effect in
    order to protect their rights. As Bostwick has already noted, the attenuated hydrological
    connection would make it difficult for anyone to demonstrate an adverse effect. This
    situation would make it difficult for senior appropriators to protect their rights.
    ¶41       The clear language of § 85-2-311, MCA, demonstrates that the legislature placed the
    burden of demonstrating lack of any adverse effect on the applicant. The legislature closed
    the Upper Missouri River Basin in recognition that significantly more water claims existed
    than water to fulfill these prior appropriations. Mont. Trout Unlimited v. Mont. Dep’t of Nat.
    Res. & Conserv., 
    2006 MT 72
    , ¶¶ 7-8, 
    331 Mont. 438
    , 
    133 P.3d 224
    . The legislature acted to
    protect the water rights of the prior appropriators. We decline to approve a shift in the
    burden of demonstrating adverse effect that could jeopardize these prior appropriators’ water
    rights.
    ¶42       Whether the District Court properly determined Bostwick’s mitigation proposal was
    adequate as a matter of law?
    15
    ¶43    Section 85-2-363(2)(g), MCA, required Bostwick to demonstrate how its mitigation
    plan would offset all adverse effects to all prior appropriators. Bostwick sought to mitigate
    its water usage with Water Right No. 41H 226700. This water right would mitigate
    Bostwick’s water usage only during the irrigation season. This water right would not
    mitigate Bostwick’s water usage during the non-irrigation season. DNRC denied Bostwick’s
    permit application due to its failure to prove no net decrease of surface water and lack of
    adverse effect for the non-irrigation season.
    ¶44    The District Court determined that no adverse effect could result as a matter of law
    from Bostwick’s water usage during the non-irrigation season.           The District Court
    recognized that Bostwick’s non-irrigation season water usage could affect adversely only one
    party – FWP. FWP further has stated that Bostwick’s irrigation season only mitigation plan
    will cause FWP no adverse effect.
    ¶45    Michael Nicklin, an expert for Bostwick, testified that Bostwick’s mitigation water
    would continue to flow in the river downstream to the Canyon Ferry Dam if Bostwick
    obtained a water right above where Interstate 90 crosses the Gallatin River. Bostwick’s
    proposed mitigation with Water Right No. 41H 226700, would withdraw water upstream of
    the Interstate 90 crossing. Sufficient flow currently exists in the Gallatin River downstream
    from the Interstate 90 crossing to fulfill all appropriators’ water rights during irrigation
    season. Bostwick’s mitigation water would flow into the Canyon Ferry Dam, therefore,
    rather than being used by another appropriator. Canyon Ferry Dam would collect all of the
    water that Bostwick mitigates during the irrigation season.
    16
    ¶46    Canyon Ferry Dam’s role in storing water likely would protect downstream water
    users when Bostwick mitigates the full 39 acre-feet of water during the irrigation season,
    rather than spreading evenly this mitigation throughout the year. FWP represented the only
    party that could be adversely affected by Bostwick’s irrigation season only mitigation plan.
    Bostwick’s settlement with FWP reflects FWP’s belief that it would not be adversely
    affected by the irrigation season only mitigation proposed by Bostwick.
    ¶47    We determined in Bostwick I that the mere fact that Bostwick had settled with
    objectors did not preclude DNRC from considering the § 85-2-311, MCA, criteria. Bostwick
    I, ¶ 21. Nothing here revises that determination. Bostwick’s settlement with FWP should
    not have precluded DNRC from considering the § 85-2-311, MCA, criteria. The settlement
    does support the notion, however, that Bostwick’s proposal would limit any adverse effect
    from the irrigation season only mitigation. In the unique circumstances presented here, with
    the Canyon Ferry Dam regulating the flow of water for downstream appropriators, the
    presence of only one party – FWP – potentially adversely affected during the non-irrigation
    season by Bostwick’s proposal, and FWP’s acknowledgment through its settlement that it
    would suffer no adverse effects during the non-irrigation season, we agree with the District
    Court that Bostwick demonstrated a lack of adverse effects for its proposed irrigation season
    only mitigation plan.
    ¶48    Whether DNRC had the authority to require Bostwick to identify a specific water right
    for mitigation?
    17
    ¶49    DNRC required Bostwick to identify exactly which water right Bostwick would use to
    mitigate its surface water depletions. Bostwick argues that DNRC should allow it to provide
    details, such as amount of water, timing, location of water, and seniority of water rights,
    without Bostwick having to specify a particular water right.
    ¶50    Section 85-2-362, MCA, imposes on DNRC the duty to determine whether a
    mitigation plan would offset depletions effectively. Bostwick does not dispute DNRC’s
    claim that DNRC routinely has required an applicant to identify the exact water right that the
    applicant plans to use for mitigation. DNRC claims that identification of the water right
    proves necessary to its full evaluation of a mitigation plan. This case demonstrates the need
    for such specificity. Bostwick’s mitigation water must reach the Canyon Ferry Dam in order
    to mitigate effectively Boswick’s net depletion. Bostwick’s own expert testified that
    Bostwick would need to acquire for mitigation a water right that withdraws upstream from
    where Interstate 90 crosses the Gallatin River, a water right senior to 1890, and a water right
    for at least 39 acre-feet per year. Bostwick’s identification of a specific water right allows
    DNRC to consider all of these factors when it evaluates the effectiveness of the mitigation
    plan. We see no prejudice caused by DNRC’s requirement in light of the fact that that
    Bostwick could mitigate with a water right with similar specifications if Bostwick could not
    purchase Water Right No. 41H 226700.
    ¶51    Whether DNRC bias substantially prejudiced Bostwick?
    ¶52    Bostwick alleges that DNRC’s bias against Bostwick during the permit application
    process violated Bostwick’s due process rights. This Court remanded to DNRC its initial
    18
    denial of Bostwick’s permit application. Bostwick I, ¶ 23. Bostwick requested that DNRC
    disqualify itself to hear the permit application on remand. Bostwick wanted the Attorney
    General to appoint a neutral party to consider Bostwick’s application. DNRC refused and
    instead appointed Scott Irvin, a DNRC employee, to hear Bostwick’s renewed request.
    Emails between Irvin and other DNRC employees suggested that Irvin had exhibited bias
    against Bostwick. Bostwick argues that the District Court improperly determined that Irvin’s
    bias did not rise to the level of an “irrevocably closed mind” as contemplated in Madison
    River R.V. Ltd. v. Town of Ennis, 
    2000 MT 15
    , ¶ 15, 
    298 Mont. 91
    , 
    994 P.2d 1098
    .
    ¶53    The District Court based its no prejudice determination on the fact that it
    independently reached the same conclusions as DNRC. We characterize DNRC’s bias as an
    “unlawful procedure.” Erickson v. State ex rel. Bd. of Med. Exam’r, 
    282 Mont. 367
    , 375,
    
    938 P.2d 625
    , 630 (1997). The mere existence of an error in the process does not mandate
    reversal. Erickson, 282 Mont. at 375, 
    938 P.2d at 630
    . The alleged error must have caused
    substantial prejudice. Erickson, 282 Mont. at 375, 
    938 P.2d at 630
    . Bostwick failed to show
    substantial prejudice. The District Court independently reached the same conclusions as
    DNRC, with the exception of the non-irrigation season mitigation proposal. Bostwick’s
    failure to demonstrate substantial prejudice relieves us of the need to consider whether
    Irvin’s bias rose to the level of having an “irrevocably closed mind.” Madison River R.V., ¶
    15.

    Justice Jim Rice, concurring.
    ¶55    In Bostwick I, Justice Nelson and I expressed dismay and concern over the
    Department’s unfair treatment of Bostwick:
    DNRC’s quick action would be commendable if it hadn’t been taken to rectify
    DNRC’s earlier malfeasance and to short-circuit a court’s review of that
    malfeasance. Then, when Bostwick asked to be heard about the denial, DNRC
    obliged Bostwick by setting a hearing in front of the same official who had
    written the DNRC’s opinion denying the permit. Whether the DNRC was
    attempting to be humorous or capricious, I do not know, but on its face this
    raises potential due process concerns.
    Bostwick I, ¶ 29 (Rice, J., concurring); see also ¶ 25 (Nelson, J., concurring). Despite this
    rebuke, the Department continued its shenanigans after the case was remanded. E-mails
    recovered by Bostwick revealed Department officials celebrating the decision in Bostwick I
    and plotting a further ambush of Bostwick upon remand in these proceedings. As the
    District Court found, “[i]t does appear that the Department exhibited bias against Bostwick
    from the beginning stages of this matter.” However, the District Court reasoned that because
    it had “upheld all but one of the Department’s substantive decisions,” that the agency’s bias
    was “irrelevant.”
    ¶56    I believe the District Court’s approach to this issue put the procedural cart before the
    horse, and I disagree that affirming an agency’s substantive decisions should necessarily
    20
    render a bias issue irrelevant. This Court has previously exercised supervisory control over
    district judge substitution because continuing the litigation could “cause uncertainty as to the
    validity of the District Court judge’s involvement and decisions in this matter” and “risks
    wasting significant resources” in the event the matter would need to be retried. Goldman
    Sachs Group, Inc. v. Second Jud. Dist. Ct., 
    2002 MT 83
    , ¶ 8, 
    309 Mont. 289
    , 
    46 P.3d 606
    .
    We revised the appellate rules to accommodate these concerns. See M. R. App. P.
    14(3)(2011); see also D.H. v. Fourth Mont. Jud. Dist. Ct., 
    2012 MT 106
    , ¶ 2, 
    365 Mont. 82
    ,
    
    278 P.3d 1010
    . We have thus recognized that an improper presiding officer can undermine
    the validity of an entire proceeding. Practically, it is difficult to measure the full reach of a
    biased decisionmaker’s impact, as it can flow to the entirety of the case, including minor
    rulings. A litigant may be faced with arguing that bias affected each adverse decision in the
    case. The Legislature has provided for substitution of hearing examiners, including for bias.
    See § 2-4-611(4); § 85-2-310(1)(b), MCA; see also In re Best, 
    2010 MT 59
    , ¶ 22, 
    355 Mont. 365
    , 
    229 P.3d 1201
     (“due process requires a fair and impartial tribunal”). And further, as a
    matter of due process, it is appropriate that the claim of bias be addressed as a threshold
    issue, with interlocutory review if necessary, and not as a final issue reviewed only for
    demonstrated prejudice.
    ¶57    Here, the Department’s proceeding should not have been conducted in the manner it
    was. In my view, bias was established because the evidence demonstrated the Department’s
    mind was irrevocably closed, and an unbiased hearing officer should have been substituted to
    hear the matter. If Bostwick had requested a new hearing as a remedy, I would vote to grant
    21
    it. However, Bostwick has not asked for such relief. Instead, Bostwick argues the bias issue
    simply to bolster its substantive arguments. Therefore, in light of the posture of this case, I
    believe the Court properly affirms on the basis of undemonstrated prejudice.
    ¶58    I likewise join in the Court’s resolution of the remaining issues.
