    OWENS, J. -     In 2003, our legislature made substantial amendments to this
    state's water law. In 2010, we found those amendments facially constitutional.
    Today, Scott Cornelius, Palouse Water Conservation Network, and Sierra Club
    Palouse Group (collectively Cornelius) bring an as-applied constitutional claim
    (among other claims) against Washington State University (WSU), the Department of
    Ecology, and the Pollution Control Hearings Board (PCHB). We find the
                                                 
    Cornelius v. Dep 't of Ecology
    No. 88317-3
    amendments were applied constitutionally and find the other claims unavailing. We
    affirm.
    FACTS
    Cornelius and WSU both draw water from the Grande Ronde Aquifer
    underlying the Palouse Basin. The aquifer is declining from overpumping. WSU has
    seven groundwater rights that serve its Pullman campus with priority dates ranging
    from 1934 to 1987. These rights are documented by claims, permits, or certificates
    depending on when the rights were perfected. Two certificates are primarily at issue
    in this case: 5070-A and 5072-A. Although the documents for some ofWSU's rights
    state that their purpose was "municipal," the documents for Certificate Nos. 5070-A
    and 5072-A state their purpose as "domestic." 4 Admin. Record (AR) Doc. 85, at 5
    (Order on Summ. J.). The holders of"mtmicipal" water rights are now entitled to
    added protections under the law. See RCW 90.14.140(2)(d). There was no added
    protection for "municipal" water rights when Ecology issued Certificate Nos. 5070-A
    and 5072-A.
    Ecology issued Certificate No. 5070-A in 1962 and Certificate No. 5072-A in
    1963. When Ecology granted those certificates, it did so on the basis of system
    capacity rather than beneficial use. Those two certificates, as well as the document
    representing WSU' s other water rights, assigned the water rights to particular wells.
    However, over the years, WSU has integrated and consolidated its water system,
    2
                                                   
    Cornelius v. Dep 't ofEcology
    No. 88317-3
    shifting almost all of its groundwater pumping from older wells to two newer wells
    drawing frmn the same aquifer. WSU admits Ecology did not previously authorize
    that integration, and no court has previously adjudicated WSU' s water rights.
    However, after the legislature enacted the municipal water law (MWL) in 2003, LAWS
    OF 2003,   1st Spec. Sess., ch. 5, WSU applied to Ecology to amend its water right
    permits and certificates to conform to its actual usage. WSU wanted to legitimize its
    integrated system, and it sought to amend its certificates to explicitly authorize it to
    withdraw the aggregate quantity of water represented by all its relevant water rights
    from the two wells it uses today. Notice ofWSU's application appeared in the
    Moscow-Pullman Daily News as required by statute, and Cornelius timely protested.
    RCW 90.03.280.
    Processing WSU' s applications required Ecology to apply a number of
    common law principles and statutes such as the common law ofabandonment, the
    water code, and the State Environmental Policy Act (SEPA), chapter 43.21C RCW.
    Ecology also applied the MWL. Ultimately, Ecology approved all but one ofWSU's
    applications. 1 Cornelius appealed Ecology's decision approving the other applications
    to the PCHB, an independent agency authorized to hear certain environmental appeals
    under RCW 43.21B.l10, on various grounds. The PCHB ruled in favor ofWSU and
    Ecology on all issues, some on summary judgment and some after a hearing.
    1
    WSU has not challenged Ecology's denial, and thus it is not before us.

    Cornelius appealed to the Whitman County Superior Court, which affirmed the
    PCHB, and to the Court of Appeals, which certified the case to us. We accepted
    certification.
    ISSUES
    1. Is the MWL unconstitutional as applied to Cornelius?
    2. Did the PCHB err by allowing Ecology to use a streamlined process for
    evaluating WSU's application?
    3. Does RCW 90.44.100 authorize WSU to amend its certificates and add well
    locations?
    4. Did the PCHB correctly apply SEPA?
    5. Did the PCHB' s summary judgment order improperly preclude Cornelius
    from presenting evidence about impairment and the public welfare?
    6. Did RCW 90.44.130 require Ecology to determine ifWSU's proposal would
    maintain a "safe sustaining yield" of groundwater?
    7. Did WSU exercise reasonable diligence in putting its water rights to
    beneficial use?
    8. Did WSU abandon Claim No. 98523?
    9. Did the PCHB err in granting WSU' s summary judgment motion regarding
    beneficial use and reasonable efficiency?

    STANDARD OF REVIEW
    The Washington Administrative Procedure Act (APA), chapter 34.05 RCW,
    governs our review ofPCHB orders. See RCW 34.05.570(1). We sit in the same
    position as the superior court and apply the AP A to the administrative record.
    Postema v. Pollution Control Hr 'gs Bd., 
    142 Wn.2d 68
    , 77, 
    11 P.3d 726
     (2000). We
    will grant relief from an order if we determine that it is based on an unconstitutional
    statute, an erroneous interpretation or application of the law, or insufficient evidence,
    among other things. RCW 34.05.570(3)(a), (d), (e). "The burden of demonstrating
    the invalidity of agency action is on the party asserting invalidity"-Cornelius in this
    case. RCW 34.05.570(l)(a). We review questions of law and an agency's application
    of the law to the facts de novo, but we give the agency's interpretation of the law great
    weight where the statute is within the agency's special expertise. Port of Seattle v.
    Pollution Control Hr'gs Bd., 
    151 Wn.2d 568

    90 P.3d 659
     (2004). We will
    overturn an agency's factual findings only ifthey are clearly erroneous. !d. at 594.
    Finally, many of the PCHB's rulings were made on summary judgment, which we
    review de novo, making the same inquiry as the PCHB. See Owen v. Burlington N

    ANALYSIS
    1. Constitutional Claims
    Cornelius argues that the MWL cannot be applied in this case without violating
    his due process rights and the separation of powers doctrine. He argues both of these
    doctrines were violated when Ecology applied the MWL to WSU and approved
    WSU' s groundwater amendment application. Cornelius claims those constitutional
    doctrines were violated when Ecology and the PCHB "reviv[ ed]" WSU' s allegedly
    relinquished groundwater rights. Appellants' Opening Br. at 20.
    Before we address Cornelius's as-applied constitutional claims, it is helpful to
    review Washington's water laws and our recent decision in Lummi Indian Nation v.
    State, 
    170 Wn.2d 247
    , 
    241 P.3d 1220
     (2010), which dealt with the facial
    constitutional challenge to the MWL underlying the conflict here.
    A. Washington Water Law and Lummi Indian Nation
    Washington, like other western territories in the late 1800s, followed a water
    law system called "prior appropriation." Ellis v. Pomeroy Improvement Co., 
    1 Wash. 572
    , 578, 
    21 P. 27
     (1889). Prior appropriation is a system of"first in time ... first in
    right," and our legislature formally recognized that system in 1917. LAws OF 1917,
    ch. 117, § 1 (currently codified as RCW 90.03.010). Prior appropriation focuses on
    the beneficial use of water and generally provides that a person's right to the
    6
                                                     
    Cornelius v. Dep 't of Ecology
    No. 88317-3
    beneficial use of water is superior to others if he or she first appropriated the water for
    beneficial use. Id.
    Washington still follows the general prior appropriation system but has a
    regulatory permit scheme to balance and prioritize competing beneficial uses of the
    state's waters. Put simply and very generally, would-be users submit applications to
    Ecology and Ecology detennines what water is available and to what beneficial use it
    can be applied before issuing permits. Lummi Indian Nation, 170 Wn.2d at 252-53;
    RCW 90.03.290(1). Permits represent inchoate water rights, which are not choate
    (i.e., vested) until perfected. Lummi Indian Nation, 170 Wn.2d at 253; RCW
    90.03.330. Before the right is perfected, the applicant still has an incomplete
    appropriative right in good standing, but he or she must act with reasonable diligence
    to perfect the right by developing the water system. RCW 90.03.320; Lummi Indian
    Nation, 170 Wn.2d at 253. Ecology can cancel the permit if the permit's terms are
    violated. RCW 90.03.320. Once the water right is perfected, Ecology issues a
    certificate. RCW 90.03.330. Importantly, the perfected right evidenced by the
    certificate relates back to the date the applicant filed the original application with
    Ecology. RCW 90.03.340. Thus, the date a water right vests is often determined by
    the date the application was filed.
    Ecology and its predecessor have applied the perfection doctrine inconsistently
    over the years. Lummi Indian Nation, 170 Wn.2d at 254-55. Initially, water users
    7
        Cornelius
            'tof Ecology
                            
    v. Dep
    No. 88317-3
    needed to both appropriate water and put it to beneficial use before they could perfect
    their right. See, e.g., OrteZ v. Stone, 
    119 Wash. 500
    , 503, 
    205 P. 1055
     (1922).
    However, in the 1950s, Ecology and its predecessor issued both permits and
    certificates based on a user's need and capacity rather than on its actual beneficial use;
    this different approach was aptly named '"pumps and pipes."' Dep 't ofEcology v.
    Theodoratus, 
    135 Wn.2d 582
    , 587,
    957 P.2d 1241
     (1998). Tension arose because of
    this inconsistency, and it led to our decision in Theodoratus.
    George Theodoratus had a water right application approved by Ecology for a
    development he planned to build. !d. Ecology's "Report of Examination" approving
    his application had language purporting to create a vested water right based on his
    development's capacity for water so long as it was built by a particular date. !d.
    Under the original report, Theodoratus would have been entitled to a certificate and
    his rights would have thus vested once he completed his water supply system and it
    was capable of delivering water-regardless of actual beneficial use. !d. Theodoratus
    was delayed in completing the development, and Ecology granted him several permit
    extensions, the last of which placed conditions on his water rights vesting. !d. at 587-
    88. The conditions provided, among other things, that his vested water right would be
    determined based on actual application of water to beneficial use, not on system
    capacity. !d. at 588. Theodoratus appealed Ecology's condition, and we eventually
    held that the relevant statutes and our common law left no doubt that Theodoratus' s
    8
        Cornelius
            'tof Ecology
                                
    v. Dep
    No. 88317-3
    vested water rights must be based on beneficial use-not system capacity. 
    Id. at 590
    .
    We noted, however, that our decision did not involve "municipal water suppliers,"
    which are treated differently under our "statutory scheme." 
    Id. at 594
    .
    Specifically, since 1967, our statutory scheme has treated water rights claimed
    for municipal water supply purposes as immune from statutory relinquishment, while
    nonmunicipal water rights may be relinquished through nonuse. LAws OF 1967, ch.
    233, § 18 (codified as RCW 90.14.180); cf LAWS OF 1967, ch. 233, § 14 (codified as
    RCW 90.14.140(2)(d)). Generally, a nonmunicipal water right holder relinquishes all
    or part of its right if it fails to beneficially use the water right for five successive years
    without sufficient cause. RCW 90.14.180; see RCW 90.14.140(2)(d). However,
    despite this favorable treatment, until recently, our laws did not define "municipal
    water supplier" or "municipal water supply purposes."
    This ambiguity in the water code, combined with our Theodoratus decision,
    caused water users concern about the validity of their water rights based on system
    capacity and whether their water rights were subject to relinquishment. In response,
    our legislature amended the water law act. Lummi Indian Nation, 170 Wn.2d at 256;
    LAWS OF 2003, 1st Spec. Sess., ch. 5; SECOND ENGROSSED SECOND SUBSTITUTE H.B.
    1338, 58th Leg., 1st Spec. Sess. (Wash. 2003) (2E2SHB 1338). In addition to
    defining "municipal water supplier" and "municipal water supply purposes" for the
    first time, the law declared that water right certificates issued prior to September 9,
    9
                                                    
    Cornelius v. Dep 't ofEcology
    No. 88317-3
    2003, for municipal water supply purposes based on system capacity were in good
    standing. Lummi Indian Nation, 170 Wn.2d at 256-57 (citing LAWS OF 2003, 1st
    Spec.Sess., ch. 5; 2E2SHB 1338; H.B. REP. ON2E2SHB 1338, at 1-2). It further
    provided that after September 9, 2003, Ecology must issue certificates based on the
    actual beneficial use ofwater. Id. at 257 (quoting RCW 90.03.330(4)). As we stated
    in Lummi Indian Nation, "The legislation essentially put the legislature's imprimatur
    on our holding in Theodoratus prospectively while confirming the good standing of
    water certificates issued under the former system." I d.
    The amendments garnered opposition from various groups and ultimately led to
    our Lummi Indian Nation decision. In that case, two groups of challengers (including
    Cornelius) brought facial constitutional challenges, arguing that the amendments,
    specifically RCW 90.03.015(3) and (4) and RCW 90.03.330(3), violated separation of
    powers and due process. Id. at 259, 265. The challengers argued the amendments
    violated separation of powers by changing the requirements we noted in Theodoratus
    for private water rights to vest and thereby unsettling our decision. Id. at 259-60. As
    discussed further below, we found no separation of powers violation because the
    legislature did not "apply the law to an existing set of facts, affect the rights of parties
    to the court's judgment, ... interfere with any judicial function," or adjudicate facts.
    Id. at 263. The challengers argued that the amendments violated due process by
    potentially depriving junior water users of vested rights by '"resurrecting'" the
    10
                                                      
    Cornelius v. Dep 't ofEcology
    No. 88317-3
    relinquished water rights of potentially senior rights holders. I d. at 268-69. Again, as
    discussed further below, we found that the amendments by themselves did not
    resurrect any relinquished rights and did not deprive junior water rights holders of
    vested property rights. I d. We left "for another day consideration of any as-applied
    challenges." Id. at 263. Today is that day.
    B. Separation ofPowers
    The doctrine of separation of powers '"preserves the constitutional division
    between the three branches of government"' and ensures that the activities of one
    branch do not "'threaten or invade the prerogatives of another."' In re Estate of
    Hambleton, 
    181 Wn.2d 802
    ,817,
    335 P.3d 398
     (2014) (quoting State v. Elmore, 
    154 Wn. App. 885
    , 905, 
    228 P.3d 760
     (2010)); Zylstra v. Piva, 
    85 Wn.2d 743
    , 750, 
    539 P.2d 823
     (1975). The legislature violates separation of powers when it applies "the
    law to an existing set of facts, affect[ s] the rights of parties to the court's judgment, ..
    . interfere[s] with any judicial function," or adjudicates facts. Lummi Indian Nation,
    170 Wn.2d at 263. The legislature is occasionally disappointed with our interpretation
    of a statute, and it may amend statutes within its sphere of authority and may
    sometimes apply the amended statute retroactively; however, the legislature may not
    retroactively reverse decisions of this court or interfere with any judicial functions.
    Hale v. Wellpinit Sch. Dist. No. 49, 
    165 Wn.2d 494
    , 509-10, 
    198 P.3d 1021
     (2009).
    "[W]hen the legislature passes a statute premised on finding an adjudicative fact" or if
    11
                                                  
    Cornelius v. Dep 't of Ecology
    No. 88317-3
    it interferes with someone's previously litigated vested rights, "it may violate
    separation of powers." Lummi Indian Nation, 170 Wn.2d at 264-65.
    Cornelius first claims that by adjudicating facts, the PCHB interpreted the
    MWL in the manner we stated in Lummi Indian Nation would violate the separation
    of powers doctrine. In that case, we were careful not to prejudge whether water rights
    holders could bring a successful as-applied challenge if their previously adjudicated
    water rights were sufficiently affected by the MWL. See id. at 265. But Cornelius's
    as-applied challenge is a thinly veiled facial challenge, and it fails.
    Cornelius argues that when the PCHB applied the MWL in this case, it changed
    the past status of WSU' s water rights-rights that had already been relinquished by
    operation of law though not yet memorialized by Ecology or in a court opinion. He
    claims that because WSU' s two certificates were not issued specifically for
    "municipal water supply purposes," WSU's failure to use the water for more than five
    years prior to 2003 relinquished WSU's water rights. Appellants' Opening Br. at 22-
    24. And because, he contends, WSU' s rights were relinquished through nonuse, the
    PCHB ran afoul of the separation of powers doctrine by applying the MWL and
    "chang[ing] that legal conclusion." Id. at 19-20.
    We disagree. Retroactive application of a statute does not necessarily violate
    separation of powers-there must be some interference either with vested rights or
    with the prerogatives of another branch of government. Hale, 165 Wn.2d at 507-1 0;
    12
        Cornelius
                                          
    v. Dep 't of Ecology
    No. 88317-3
    Lummi Indian Nation, 
    170 Wn.2d 262
    . In Lummi Indian Nation, we already held that
    retroactively applying the MWL does not violate the constitution-including RCW
    90.03.560, the amendment that allows for water rights to be relabeled using the new
    definition of"municipal water supply purposes." 170 Wn.2d at 260-63, 272. We
    found that allowing this statute to apply retroactively is a legislative policy decision-
    confirming existing rights-not a factual adjudication. Id. at 264-65. Although we
    stated that retroactive application of this statute could unconstitutionally disturb
    previously litigated adjudicative facts, we must be faced with previously litigated
    adjudicative facts in order to find an as-applied constitutional violation.
    Here, there are no previously litigated adjudicative facts regarding WSU's past
    water rights. Accordingly, there is no way that the PCHB violated the separation of
    powers doctrine by applying the MWL to WSU' s certificates-there were no
    "adjudicative facts" the PCHB could have upset. I d. at 265. The PCHB merely
    applied the MWL definition to WSU in the current adjudication. That is the precise
    general application of the MWL we found constitutional in Lummi Indian Nation. I d.

    Cornelius would have us overrule Lummi Indian Nation in all but name.
    Cornelius would have us rule that the purpose of use stated on water right certificates
    must control-that only certificates stating a "municipal" purpose can be treated as
    municipal. That holding would invalidate RCW 90.03.560 on its face and overrule

    Cornelius v. Dep 't of Ecology
    No. 88317-3
    Lummi Indian Nation, where we held that the new definition of "municipal water
    supply purposes" applies retroactively, even to rights that were not originally labeled
    "municipal." Id. at 268-69.
    RCW 90.03.560 demonstrates that the legislature foresaw that too much weight
    might be placed on the characterizations of water rights holders and water rights use
    on certificates issued before "municipal" was defined. The legislature created a
    mechanism to fix this problem. The statute states in relevant part:
    When requested by a municipal water supplier or when processing a
    change or amendment to the right, the department shall amend the water
    right documents and related records to ensure that water rights that are
    for municipal water supply purposes, as defined in RCW 90.03.015, are
    correctly identified as being for municipal water supply purposes. This
    section authorizes a water right or portion of a water right held or
    acquired by a municipal water supplier that is for municipal water supply
    purposes as defined in RCW 90. 03.015 to be identified as being a water
    right for municipal water supply purposes.
    RCW 90.03.560 (emphasis added). Thus, the legislature recognized that some water
    rights had been issued for municipal purposes under nonmunicipallabels and
    provided a simple mechanism to fix that problem. And as we held in Lummi Indian
    Nation, allowing this statute to apply retroactively is a legislative policy decision-
    confirming existing rights-not a factual adjudication. 170 Wn.2d at 264-65.
    This case exemplifies the labeling problem the legislature sought to resolve in
    passing RCW 90.03.560. When the relevant certificates were issued in 1962 and
    1963, Ecology did not have a reason to be precise about distinguishing "municipal"
    14
                                                 
    Cornelius v. Dep 't of Ecology
    No. 88317-3
    and domestic uses because "municipal water supply purposes" was undefined and the
    legislature did not give municipal suppliers an exemption from relinquishment until
    1967. See id. at 255-56; LAWS OF 1967, ch. 233, § 14 (currently codified as RCW
    90.14.140). Thus, Ecology could have issued domestic supply certificates to entities
    that were functionally municipal and vice versa.
    That is clearly the case here. WSU is a major public university that provides
    on-campus housing for thousands of residents. The relevant certificates give WSU
    the right to pump over 971 million gallons of water per year to service its large
    population, and Ecology's report prepared in 1962 in response to WSU' s permit
    application for Certificate No. 5070-A specifically states that the recommended
    quantity is based on "the anticipated amount required for 15,000 students." Ex. A-11,
    at 2. Moreover, it is undisputed that WSU's water system far exceeds the necessary
    number of residential service connections to qualify as a municipal water supplier
    under the current definition of"municipal water supply purposes." It makes no sense
    to say that in 1962 and 1963, Ecology issued WSU the right to pump over 971 million
    gallons of water per year but never intended WSU to use that water for municipal
    purposes. We refuse to elevate form over substance and overrule Lummi Indian
    Nation. The PCHB correctly confirmed WSU's existing water rights by applying
    RCW 90.03.560. Under that statute, WSU is deemed to have always been a municipal

    No. 88317-3
    supplier, and that determination does not violate separation of powers because it
    upsets no adjudicative facts.
    C. Due Process
    Cornelius next claims that the PCHB violated his due process rights as a junior
    water user when it "revive[ d)" WSU's relinquished senior water rights. Appellants'
    Opening Br. at 20. He argues the revival moved him "further down the line" of water
    rights. !d. Again, Cornelius's as-applied challenge is a thinly veiled facial challenge
    and fails. 2
    Cornelius again cites to Lummi Indian Nation to support his argument. He
    claims we held in that case that the MWL did not resurrect rights already lost and that
    when water right applicants apply to amend their certificates, Ecology is required to
    determine which water rights have been relinquished pursuant to RCW 90.03.330(2)
    and RCW 90.44.1 00. Thus, he argues that here, Ecology unconstitutionally applied
    the MWL to WSU' s water rights because it resurrected a relinquished water right.
    2 Cornelius argues a separate procedural due process violation, asserting that "[t]he
    PCHB's limitation on Cornelius' impairment evidence prejudiced his ability to protect
    his rights in violation of procedural due process." Appellants' Opening Br. at 20. He
    fails to cite to the record or provide details about how the PCHB limited his evidence,
    and he merely cites Motley-Motley, Inc. v. Pollution Control Hearings Bd., 
    127 Wn. App. 62
    , 
    110 P.3d 812
     (2005), for the broad principle that parties must be prejudiced regarding
    preparation to establish due process violations in administrative proceedings. !d. We
    will not reach arguments unsupported by adequate argument and authority. Saunders v.

        Cornelius
                                       
    v. Dep 't of Ecology
    No. 88317-3
    We disposed of this argument in Lummi Indian Nation. We held in Lummi
    Indian Nation that merely relabeling a previously granted water right as "municipal"
    does not violate due process, provided the water user falls under the new municipal
    definition. See 170 Wn.2d at 265-67. We stated,
    [T]hese amendments confirm what the department has already declared
    (that certain water rights are rights in good standing) and statutorily
    define something that had previously been statutorily undefined (the
    meaning of municipal water supplier). RCW 90.03.015, .260, .330, .386,
    .560. Of themselves, these changes to the law do not violate due
    process.
    Id. at 266-67. Here, Ecology merely applied RCW 90.03.560 and RCW 90.03.015
    retroactively to WSU to determine that WSU' s water rights were valid and met the
    definition of"municipal water supply purposes." 4 ARDoc. 85, at 14-15 (Order on
    Summ. J.). This is precisely the kind of action we found constitutional in Lummi
    Indian Nation. If we ruled for Cornelius, Ecology would regularly violate a junior
    water right holder's due process rights when it applied RCW 90.03.560 to amend a
    senior municipal holder's water right, the precise argument we rejected in Lummi
    Indian Nation.
    17
        Cornelius
                                         
    v. Dep 't of Ecology
    No. 88317-3
    While there may be an unconstitutional application of the MWL, we find none
    in this case. 3 Cornelius's water rights are junior to WSU's. As observed in Lummi
    Indian Nation, "Junior rights holders always take their water rights subject to the risk
    that there may be no water to fulfill those rights." 170 Wn.2d at 267 (emphasis
    added). We do not mean to minimize Cornelius's need for water and realize that
    Washington's prior appropriation water law system can lead to unpleasant outcomes.
    However, it is the legislature's prerogative to categorize water uses and decide which
    categories will be relinquished by nonuse. It has done so with the MWL, and under
    the MWL, Cornelius's claim fails.
    2. Ecology's Streamlined Process
    Cornelius next argues that the PCHB erred in approving Ecology's streamlined
    process for evaluating WSU's application. Specifically, he claims that the
    streamlined process conflicts with the MWL' s requirement that when a person applies
    to amend his or her water right, Ecology must conduct a tentative determination of the
    extent and validity of the water right. He concludes from that requirement that the
    streamlined process is ultra vires because it contradicts our water laws. His claim
    3 If Ecology applied the MWL in a way that invalidated an individual's vested water
    right, it might well violate due process. See Lummi Indian Nation, 170 Wn.2d at 268-69.
    But junior rights holders always take their rights subject to the possibility that senior
    rights holders' use will limit, possibly severely, the amount ofwater available. That is a
    consequence of scarcity, not a due process violation.
    18
        Cornelius
                                          
    v. Dep 't ofEcology
    No. 88317-3
    suffers from the same erroneous characterization of the MWL we outlined above and
    fails.
    An agency's policy is ultra vires if it exceeds its statutory authority. S. Tacoma
    Way, LLC v. State, 
    169 Wn.2d 118
    , 122-23, 
    233 P.3d 871
     (2010). The parties agree
    that when someone applies to amend their certificates or change the manner or place
    of use of the water, Ecology must conduct a tentative determination of the extent and
    validity of the applicant's water rights pursuant to RCW 90.44.100. We accept their
    agreement for the limited purposes of deciding the issue presented. Tentative
    determinations generally include Ecology staff examining an applicant's historic
    water use, often looking at year-to-year use, to determine if the applicant relinquished
    rights. However, Ecology has a streamlined policy for making "simplified" tentative
    determinations when relinquishment is not an issue. 2 AR Doc. 23, Ex. 2, at 3 (Decl.
    of Patrick Kevin Brown in Supp. ofWSU's Mot. for Partial Summ. J.). Under this
    streamlined policy, Ecology's staff does not generally require applicants to
    demonstrate their year-to-year water use because relinquishment is not an issue.
    Intuitively, instances where Ecology permits the streamlined policy would include
    when the water right is for a municipal water supply under RCW 90.03.330(3), since
    those rights are immune from relinquishment. RCW 90.14.140(2)(d).
    Here, Ecology made a simplified tentative determination of some of WSU' s
    water rights, which Cornelius challenges, arguing that the MWL still required
    19
        Cornelius
            'tof Ecology
                           
    v. Dep
    No. 88317-3
    Ecology to look at WSU' s historic nonuse of its water rights and revoke any
    relinquished rights.
    Accepting Cornelius's argument would require us to ignore RCW 90.03.560
    and our holding in Lummi Indian Nation. Here, Ecology appropriately applied RCW
    90.03.560 and RCW 90.03.015 retroactively to WSU to determine that WSU's water
    rights were valid and met the definition of"municipal water supply purposes." 4 AR
    Doc. 85, at 14-15 (Order on Summ. J.). Ecology applying the streamlined policy to
    WSU is consistent with the MWL because WSU' s water rights were for municipal
    water supply purposes and immune from relinquishment. Accordingly, Ecology's
    action was not ultra vires and Cornelius's claim fails.
    3. Amending Certificates To Add Well Locations
    Cornelius next challenges the PCHB' s summary judgment order allowing WSU
    to amend its certificates to add well locations under RCW 90.44.100. He argues that
    under our decision in R.D. Merrill Co. v. Pollution Control Hearings Bd., 
    137 Wn.2d 118
    , 
    969 P.2d 458
     (1999), in order to amend a certificate, the water right documented
    by the certificate must be completely perfected. And, because three of WSU' s
    certificates involve water rights that WSU never fully perfected, the certificates could
    not be amended. Cornelius's argument is based on a misunderstanding of the MWL
    and fails.
    20
        Cornelius
                                        
    v. Dep 't of Ecology
    No. 88317-3
    RCW 90.44.100 authorizes individuals to apply to amend their permits or
    certificates to add well locations. RCW 90.44.100(1). InR.D. Merrill, we said that
    because RCW 90.44.100 includes the word "permit," it expressly does not require
    applicants to perfect their water rights through beneficial use before they can amend a
    groundwater permit. 137 Wn.2d at 130. That case did not involve certificates or
    water rights for municipal supply purposes. See id.
    The plain language ofRCW 90.44.100 and the logic of our decision in R.D.
    Merrill, combined with the operation of the MWL, allows water users who possess
    unperfected water rights documented by certificates to amend them to add well
    locations, at least where the certificates were originally based on system capacity and
    were for municipal supply purposes. RCW 90.44.100 itself does not require
    certificate holders to perfect any unperfected rights before amending them to add well
    locations. In R.D. Merrill, we allowed permit holders to amend their unperfected
    rights specifically because the statute mentioned "permit" and thus contemplated that
    permit holders need not have beneficially used water. 137 Wn.2d at 130. Although
    we hinted that in the certificate-holder context, water would likely need to be put to
    beneficial use before it could be amended under RCW 90.44.100, it was because
    certificates issue only once water has been put to beneficial use-not because RCW
    90.44.100 requires it. !d. at 133. In other words, in many cases, certificate holders
    would need to put their water rights to beneficial use because if they failed to do so,
    21
        Cornelius
             't                          
    v. Dep    of Ecology
    No. 88317-3
    Ecology could find those rights relinquished under RCW 90.44.100 once the applicant
    applied to amend. See id. at 133 n.7. But, in scenarios involving system capacity
    certificates for municipal supply purposes, relinquishment is simply not an issue.
    System capacity certificates for municipal supply purposes represent rights "in good
    standing," i.e., the water rights are deemed perfected, even if the rights were not
    actually put to beneficial use. RCW 90.03.330(3).
    As discussed above, WSU' s water rights are represented by system capacity
    certificates for municipal supply purposes. Thus, WSU did not need to take any
    action to fully perfect its rights before amending them under RCW 90.44.100 because
    they are deemed perfected. Accordingly, Cornelius's claim fails.
    4. SEPA
    Cornelius next argues that Ecology failed to comply with SEPA when it
    processed WSU's applications. The PCHB granted Ecology's summary judgment
    motion on this issue, and Cornelius appeals, arguing that Ecology should have
    supplemented its SEPA review. His claim fails.
    SEPA is a procedural law that ensures state agencies, among others, consider
    environmental impacts and alternatives before taking certain actions. Save Our Rural
    Env't v. Snohomish County, 
    99 Wn.2d 363
    , 371, 
    662 P.2d 816
     (1983). If no
    categorical exemption from SEPA exists, the relevant agency or actor proposing a
    development must meet certain environmental review and documentation

    requirements. WAC 197-11-310. First, applicants must prepare an "environmental
    checklist" to describe basic information about a proposal's environmental impacts.
    WAC 197-11-960. The responsible agency4 reviews the checklist to determine if an
    environmental impact statement (EIS) is required. WAC 197-11-330. An EIS is
    required if the responsible agency reasonably believes that a proposal may have a
    significant adverse impact on the environment. WAC 197-11-330(4). Ifthe agency
    determines that the action will not significantly impact the environment, the agency
    issues a determination of nonsignificance (DNS), which ends the environmental
    review. WAC 197-11.:.340; 24 TIMOTHYBUTLER&MATTHEWKING, WASHINGTON
    PRACTICE: ENVIRONMENTALLAW AND PRACTICE§ 17.3, at 195 (2d ed. 2007). Even
    if the agency issues a DNS, though, it must create a supplemental EIS or prepare a
    new "determination" if"[n]ew information" indicates the proposed action may
    significantly affect environmental quality. WAC 197 -11-600(3 )(b )(ii). "New
    information" includes discovering misrepresentation or the lack of material disclosure.
    Id. The agency's determination is entitled to "substantial weight." RCW 43.21 C.090.
    We apply the "clearly erroneous" standard of review to an agency's DNS. Norway
    4 Meaning  the agency that seeks to develop or the agency that is presented with a
    proposal for development. See WAC 197-11-050. If more than one agency is involved, a
    lead agency must be designated. WAC 197-11-050. The lead agency is the one with the
    main responsibility for complying with SEPA's procedural requirements, and it is also
    responsible for preparing environmental impact statements. WAC 197-11-050(2).

    87 Wn.2d 267
    ,275-76,
    552 P.2d 674
     (1976).
    Here, WSU was the lead agency, and it prepared an environmental checklist
    and issued a DNS. The checklist and DNS did not address whether WSU, by
    integrating its water system, would increase groundwater withdrawals and exacerbate
    the declining water level in the aquifer. When Ecology processed WSU's application,
    it relied on WSU' s DNS without adding a supplemental EIS or preparing a new
    determination. Cornelius argues that when Ecology allowed WSU to amend and
    integrate its water system, it expanded WSU' s water rights, allowing it to pump more
    groundwater than legally allowed. He claims Ecology was thus obligated under
    SEPA to supplement WSU's DNS based on the "'new information'" ofWSU's
    increased pumping capacity and its impact on the aquifer. Appellants' Opening Br. at
    33.
    Cornelius's argument is unpersuasive. As we stated above, Ecology and the
    PCHB did not expand WSU's water rights in approving WSU's application; rather,
    they confirmed WSU's rights by applying RCW 90.03.560. The PCHB correctly
    noted that the amendment does not allow WSU to pump any more water than it
    currently has a vested right to pump-it merely allows WSU to more cost effectively
    utilize its existing rights. Thus, Ecology did not need to supplement WSU' s DNS
    24

    v. Dep
    No. 88317-3
    because there was no "new information." Accordingly, we affirm the PCHB's
    summary judgment order on this issue.
    5. Impairment and Public Welfare
    Cornelius next argues that through its "unconstitutional interpretation of the
    MWL," the PCHB improperly limited the evidence and argument that would, he
    contends, have shown that amending WSU' s water rights certificates would impair
    existing rights and be detrimental to the public welfare. 
    Id. at 34
    . Cornelius's claim
    is meritless because it is predicated on the same flawed argument that WSU' s water
    rights are being expanded under the MWL that we rejected above. Properly
    understood, the PCHB did not expand or revive relinquished water rights; rather, it
    confirmed WSU's existing water rights. Accordingly, Cornelius's claim fails.
    6. Safe Sustaining Yield
    Cornelius next argues that when WSU applied to amend its water rights
    certificates, RCW 90.44.130 required Ecology to determine ifWSU's proposal would
    maintain a safe sustaining yield of groundwater. 
    Id. at 35
    . Cornelius's claim again
    fails.
    Generally, RCW 90.44.130 protects "prior appropriator[s]," i.e., senior water
    users, from subsequent appropriators overdrafting public groundwater. The statute
    protects senior users by giving Ecology the power to limit subsequent appropriators'
    25
        Cornelius
                                         
    v. Dep 't of Ecology
    No. 88317-3
    withdrawals to an amount that will "maintain and provide a safe sustaining yield in
    the amount of the prior appropriation." RCW 90.44.130.
    Here, Ecology did not apply the safe sustaining yield provision to WSU and
    interpreted the statute to mean that the safe sustaining yield requirement applies only
    to new applications for water rights, not to applications to amend existing water rights
    certificates. The PCHB agreed with Ecology's interpretation. Cornelius argues
    Ecology's interpretation was erroneous for two reasons. First, he contends Ecology's
    erroneous interpretation stems from its unconstitutional interpretation of the MWL
    expanding WSU's rights. For the reasons above, we reject this argument. Second, he
    contends that whenever an existing water user seeks to amend his or her water rights,
    RCW 90.44.130 broadly mandates that Ecology limit the user's groundwater to
    maintain a safe sustaining yield for other users-the statute does not apply only when
    Ecology evaluates new permits. We disagree.
    Although RCW 90.44.130 clearly protects senior water users against
    overdrafting by subsequent users, it is unclear whether the senior users' enjoyment of
    a "safe sustaining yield" applies only to new users who wish to appropriate water or if
    it applies to existing users who seek to amend. However, here, that is an academic
    question. WSU is the senior water user, not Cornelius. Thus, Ecology and the PCHB
    did not err by not applying the safe sustaining yield provision to WSU.

    7. Reasonable Diligence
    Cornelius again challenges the formally inchoate portions of several of WSU' s
    water rights, this time arguing that they are invalid because they were not put to
    beneficial use with "reasonable diligence." Appellants' Opening Br. at 37.
    Cornelius's claim again fails.
    When individuals apply to amend their water rights certificates under RCW
    90.44.100, rights represented by system capacity certificates for municipal supply
    purposes are rights "in good standing," i.e., the rights are deemed perfected, even if
    they were not actually put to beneficial use. RCW 90.03.330(3). However, although
    the water need not actually have been put to beneficial use for the rights to remain in
    good standing, the water rights must still be "prosecuted with reasonable diligence" to
    remain valid. RCW 90.03.460. What constitutes reasonable diligence depends on the
    circumstances, including the magnitude of the project, the engineering and physical
    features to be encountered, and public interests. RCW 90.03.320. Another
    circumstance relevant in the municipal supply purposes context is "delays that may
    result from planned and existing conservation and water use efficiency measures." 
    Id.
    One of the purposes of the reasonable diligence requirement is to avoid a party
    speculating in water rights (i.e., acquiring water rights for future profit rather than
    specifically intending to apply them to a beneficial use). See R.D. Merrill, 137 Wn.2d
    at 130-31.

    Here, four ofWSU's water rights are at issue, represented by Certificate Nos.
    5070-A, 5072-A, and G3-22065C, and Permit No. G3-28278P. WSU has not
    historically used the quantity of water listed on those certificates and the one permit
    since the priority dates of those water rights-1962, 1963, 1973, and 1987
    respectively. Thus, WSU has not put to beneficial use the full extent of those water
    rights for several decades. There is no evidence that WSU is speculating its water
    rights for profit; WSU exclusively exercises its rights to serve its Pullman campus.
    Over those decades, WSU has developed as an institution, increasing its enrollment
    and developing additional facilities. Even with this growth, in recent years WSU's
    water use has actually declined because it has taken water conservation measures.
    Here, we find WSU has exercised reasonable diligence. Although in other
    circumstances failing to use the full extent of one's water rights for decades might not
    meet the reasonable diligence requirement, here WSU meets the requirement because
    of its unique situation and development throughout the decades. WSU is a large
    public institution that has developed new facilities and increased enrollment over the
    years. It is in the unusual position of being unable to predict or plan its own growth
    because its budget and enrollment targets are largely controlled by the legislature.
    Additionally, WSU is not speculating its water rights, and it has not exercised the full
    extent of its rights at least in part because of water conservation measures.
    Considering these circumstances, taking away WSU' s water rights for lack of

    No. 88317-3
    reasonable diligence would hinder WSU' s ability to educate students, and it would
    essentially punish WSU for taking water conservation measures. Accordingly, WSU
    exercised reasonable diligence and Cornelius's claim fails.
    8. Abandonment of Claim No. 98523
    Cornelius next argues that WSU abandoned its water right represented by
    Claim No. 98523. His claim fails.
    "Abandonment is the intentional relinquishment of a water right." Okanogan
    Wilderness League, Inc. v. Town ofTwisp, 
    133 Wn.2d 769
    , 781,
    947 P.2d 732
     (1997).
    Abandonment requires a two-part showing: nonuse plus an intent to abandon the
    water right. See 
    id.
     The party alleging abandonment has the burden of proof. !d.
    However, "long periods of nonuse raise a rebuttable presumption of intent to
    abandon" a water right, and the burden shifts to the water right holder to give reasons
    justifying the nonuse. 
    Id.
    Here, WSU filed Claim No. 98523 in 1974, and the claim identifies WSU's
    Well No.2 as the source or point of withdrawal. The water right represented by this
    claim has £LNiority date of 1938, which is also the year Well No.2 was drilled. WSU
    stopped using Well No.2 as a water source in 1978 because of a misaligned hole and
    low water level, and WSU decommissioned the well in 1995, using it as a monitoring
    well instead. WSU's 2002 Water System Plan formally denoted Well No.2 as being
    abandoned. However, WSU's 2002 Water System Plan also identified Claim No.

        Cornelius
             't
    v. Dep

    No. 88317-3
    98523 as an existing water right, listing quantities of water for its current and
    forecasted water right tables. When WSU prepared its applications to amend its water
    rights, the responsible employee corresponded with Ecology, and the employee
    assumed that WSU's abandonment of Well No.2 meant that WSU had abandoned the
    water right itself. Ecology informed the employee that when a person abandons a
    well, he or she does not necessarily abandon the associated water right.
    Cornelius argues he demonstrated a long period of nonuse because WSU
    ceased using Well No.2 in the late 1970s, and he says that unauthorized pumping
    from other wells cannot make up for WSU not using Well No.2. He argues WSU
    cannot rebut the presumption of an intent to abandon Claim No. 98523 because WSU
    listed Well No.2 as abandoned and WSU (through its agent employee) assumed
    Claim No. 98523 was abandoned.
    Assuming without deciding that Cornelius demonstrated a long period of
    nonuse, WSU demonstrated that it did not intend to abandon Claim No. 98523.
    Cornelius's argument heavily relies on Okanogan Wilderness League. In that case,
    the town of Twisp had a water right dating back to 1912 to divert water from the
    Twisp River. 
    Id. at 772
    . At least since 1948, Twisp stopped diverting from the river
    and instead drew water from wells in the town. !d. When Twisp belatedly applied for
    groundwater certificates for the wells in 1967 and 1971, "it did not mention the 1912
    water right even though the application forms asked whether there were any other
    30
        Cornelius
            't

    No. 88317-3
    water rights appurtenant to the lands served by the groundwater withdrawals." 
    Id. at 783
    . In the 1990s, Twisp applied to Ecology for a new water right and an Ecology
    employee discovered a certificate for the 1912 right. !d. at 773. Twisp then sought to
    use the discovered 1912 right to withdraw water from two new wells. 
    Id.
     The only
    evidence Twisp had that it did not abandon the 1912 water right was Twisp's
    continuing existence and need for a water supply. 
    Id. at 784
    . We found Twisp's
    showing inadequate and held that Twisp abandoned the 1912 right. 
    Id. at 786
    .
    Here, WSU shows it did not intend to abandon Claim No. 98523. Unlike
    Twisp in Okanogan Wilderness League, where Twisp apparently forgot it had the
    1912 right and failed to list the right on subsequent applications, here WSU never
    forgot about Claim No. 98523. Although WSU listed the claim's associated well as
    abandoned in 2002, it also stated that the water right represented by the claim existed,
    listing quantities of water for its current and forecasted water right status tables. The
    record indicates WSU's employee's mistake about Claim No. 98523 being abandoned
    was a theoretical concern he had while preparing WSU' s applications to amend its
    water rights, not a demonstration of an intent to abandon the claim. Accordingly,
    WSU did not abandon Claim No. 98523 and Cornelius's claim fails.

    9. Beneficial Use and Reasonable Efficiency
    Cornelius next argues that the PCHB erred in granting WSU' s summary
    judgment motion on whether WSU' s irrigation of its golf course complied with
    beneficial use requirements. We disagree.
    In water law, "beneficial use" encompasses two principles. In re Rights of
    Surface & Ground Waters of Marshall Lake & Marshall Creek Drainage Basin, 
    121 Wn.2d 459
    , 468, 
    852 P.2d 1044
     (1993). First, "beneficial use" refers to the types of
    activities for which water may be used (e.g., irrigation or agriculture). 
    Id.
     Second,
    "beneficial use" determines the measure of a person's water right (i.e., a person is
    entitled to the amount of water he or she has traditionally put to beneficial use). 
    Id.
    Closely related to the idea of beneficial use is an appropriator's duty to avoid waste-
    when someone appropriates water to beneficial use, that appropriation must be
    reasonably (not absolutely) efficient. 
    Id. at 472
    . Whether a beneficial use is
    reasonably efficient turns on a variety of factors, such as local custom, the relative
    efficiency of irrigation systems in common use, and the costs and benefits of
    improvements to irrigation systems. 
    Id. at 475
    .
    Here, Cornelius originally alleged that WSU's irrigation of its golf course did
    not meet the reasonable efficiency requirement for beneficial use. WSU moved for
    summary judgment, and to defeat WSU' s summary judgment motion, Scott Cornelius
    submitted a declaration describing personal observations he made of WSU' s golf
    32
        Cornelius
             't                          
    v. Dep    of Ecology
    No. 88317-3
    course while driving or bicycling past it, including photographs and temperature data.
    In his declaration, Scott Cornelius says he saw, among other things, sprinklers
    operating during the day when local temperatures were in the 90s and water runoff on
    hillsides adjacent to the golf course. The PCHB granted WSU's summary judgment
    motion, saying that Scott Cornelius's personal observations could not meet his burden
    of showing a triable issue of fact regarding reasonable efficiency according to the
    relevant legal factors in Rights ofSurface & Ground Waters. Additionally, the PCHB
    stated that Scott Cornelius's "allegations may be more properly evaluated in the
    context of an enforcement action." 4 AR Doc. 85, at 28 (Order on Summ. J.).
    Cornelius now argues that the PCHB erred by (1) applying the wrong summary
    judgment standard by ruling that expert testimony was required to defeat summary
    judgment and (2) ruling that Ecology lacks the authority to evaluate reasonable
    efficiency when it reviews groundwater amendment applications (i.e., that reasonable
    efficiency can be reviewed only in an enforcement action).
    Cornelius's arguments fail. First, the PCHB did not rule that expert testimony
    was required to defeat summary judgment. Rather, it said that "the observations of
    Scott Cornelius, who is admittedly not an expert in this area, along with the
    photographs and temperature data, fail to establish a genuine dispute about the
    reasonable efficiency ofWSU's water use." !d. The PCHB properly found Scott
    Cornelius's observations insufficient to show triable questions of fact regarding
    33
        Cornelius
            't                             
    v. Dep   of Ecology
    No. 88317-3
    reasonable efficiency according to the relevant legal factors in Rights ofSurface &
    Ground Waters. Scott Cornelius's personal observations about the sprinklers tell us
    nothing about local custom, the relative efficiency of commonly used irrigation
    systems, or costs and benefits associated with improvements to irrigation systems-
    the relevant legal inquiries under Rights of Surface & Ground Waters. At best, Scott
    Cornelius's evidence establishes that WSU's sprinkler system is not absolutely
    efficient, which is not required for reasonable efficiency. Accordingly, his challenge
    fails.
    Second, the PCHB did not rule that Ecology lacked the authority to evaluate
    reasonable efficiency when it reviews groundwater amendment applications. The
    PCHB merely stated that it thought Scott Cornelius's "allegations may be more
    properly evaluated in the context of an enforcement action," not that Ecology lacked
    the authority to evaluate reasonable efficiency. !d. Thus, Cornelius's second
    argument is based on a misunderstanding of the PCHB's summary judgment order.
    Accordingly, Cornelius's claims fail.
    10. Permit No. G3-28278P
    Cornelius next argues that the PCHB erred when it ruled after a hearing that
    Ecology was not required to reduce the water quantity authorized under Permit No.
    G3-28278P. Cornelius claims that because Permit No. G3-28278P is supplemental to
    Claim No. 098524 (which Ecology found invalid), Ecology should have subtracted

    No. 88317-3
    the water quantity associated with Claim No. 098524 from Permit No. G3-28278P.
    We disagree.
    The groundwater code contains a prohibition on enlargement of rights. See
    RCW 90.44.100(2)(c). It prohibits Ecology from authorizing additional wells as
    points of withdrawal if the combined total withdrawal from the original and additional
    well enlarges the rights conveyed by the original permit or certificate. !d. We will
    grant relief from an agency order resulting from an adjudicative proceeding if the
    order is not supported by substantial evidence. RCW 34.05.570(3)(e). "[S]ubstantial
    evidence is 'a sufficient quantity of evidence to persuade a fair-minded person of the
    truth or correctness of the order."' King County v. Cent. Puget Sound Growth Mgmt.

    Patrol, 
    84 Wn. App. 663
    ,673,
    929 P.2d 510
     (1997)).
    Here, Ecology issued a report of examination (ROE) regarding Permit No. G3-
    28278P, informing WSU that the permit is "for supplemental water only" and that the
    "waters to be appropriated from Well No.7 will serve to replace, as necessary, those
    waters originally authorized or claimed for appropriation from Wells No. 1, 3 and 4."
    Ex. A-26, at 3. In other words, Ecology granted the permit to supplement the water
    WSU was already authorized to appropriate under its primary water rights. The
    permit itself contains the following language:
    The quantities granted under this permit are issued less those
    amounts appropriated under Ground Water Certificate No. 5070-A and
    35

    No. 88317-3
    Ground Water Claims No. 098522 and No. 098524. The total combined
    withdrawal under this permit and Ground Water Certificate No. 5070-A
    shall not exceed 2500 gallons per minute, 2260 acre feet per year.
    Ex. A-25, at 2. The PCHB conducted a hearing to determine whether Ecology meant
    "supplemental" to mean that the water right represented by Permit No. G3-28278P
    was valid only to the extent that the primary (older) water rights were valid, or
    whether "supplemental" meant that the permit was an alternate way for WSU to
    appropriate its previously authorized rights. 4 AR Doc. 89, at 30-31 (Findings of
    Fact, Conclusions of Law & Order). After examining the language in the permit and
    the ROE, the PCHB determined that Permit No. G3-28278P was intended as an
    alternate source of water for WSU and that the amount of water authorized under the
    permit was not legally dependent on WSU's existing water claims. Thus, the PCHB
    did not require WSU to subtract the amount of water authorized in invalid Claim No.
    098524 from Permit No. G3-28278P because the permit merely represented an
    alternate source of water for WSU. Cornelius claims the PCHB erred, arguing that the
    permit's validity depends on the preexisting water rights' validity.
    Cornelius contends that the permit's language and its status as "supplemental"
    necessarily means that the permit's validity depends on the preexisting water rights'
    validity. We find that the evidence the PCHB relied on-the language of the permit
    itself-is sufficient to persuade a fair-minded person of the truth or correctness of the

    finding. Accordingly, the PCHB's finding is supported by substantial evidence and
    Cornelius's claim fails.
    11. Attorney Fees
    Cornelius requests attorney fees pursuant to RCW 4.84.350. That statute
    allows for attorney fees when a qualified party prevails in judicial review of an agency
    action. Here, Cornelius does not prevail. Thus, we deny the request for attorney fees.
    CONCLUSION
    The legislature substantially amended this state's water law in 2003,
    categorizing water uses and deciding which categories would be relinquished through
    nonuse. In Lummi Indian Nation, we found those amendments facially constitutional.
    We find the amendments were constitutionally applied in this case and reject
    Cornelius's remaining claims. We affirm.

    MADSEN, C.J. (dissenting)-It is well settled Western water law, as well as the
    law of this state, that municipal uses were not the same as domestic and community
    domestic and stock water uses under Washington law prior to the 2003 amendment of our
    state water laws, and a water right granted in the early 1960s for domestic and
    community domestic and stock water uses was not a right to put water to municipal use.

    in the North Cascades have lost 18 to 32 percent of their total volume since 1983 and have
    shrunk by 50 percent in the last century, placing them at levels not seen in 4,000 years. See

    1967 the legislature enacted relinquishment statutes subjecting water rights issued for
    community domestic and stock water uses and domestic uses to relinquishment. 2
    Rather than properly applying the relinquishment statutes to the water rights at
    issue here, the majority instead applies the 2003 laws governing municipal water uses to
    recharacterize domestic uses to mean municipal uses and thus defeat statutory
    relinquishment. This application of the 2003 amendment conflicts with relinquishment
    statutes and fails to recognize the important policy decisions underlying these statutes.
    Consistent with our prior decision in Lummi Indian Nation v. State, 
    170 Wn.2d 247

     (2010), I would hold that the relinquished rights in question cannot

    2 Noting that the "future growth and development of the state is dependent upon effective
    management and efficient use of the state's water resources," the legislation's stated purpose is
    in relevant part "to cause a return to the state of any water rights which are no longer exercised
    by putting said waters to beneficial use." LAWS OF 1967, ch. 233, § 1. The legislature found
    "[ e]xtensive uncertainty" as to the volume of private claims to water in the state and that such
    uncertainty "seriously retards the efficient utilization and administration of the state's water
    resources, and impedes the fullest beneficial use thereof." Id. § 2(1), (2). The legislah1re further
    found that "[a] strong beneficial use requirement as a condition precedent to the continued
    ownership of a right to withdraw or divert water is essential to the orderly development of the
    state"; that"[ e]forcement of the state's beneficial use policy is required by the state's rapid
    growth"; that "[a]ll rights to divert or withdraw water ... must be subjected to the beneficial use
    requirement"; and that "[t]the availability for appropriation of additional water as a result of the

    Discussion
    In Lummi Indian Nation, we held that legislation enacted in 2003 governing
    municipal water supplies and suppliers was not facially unconstitutional. However, we
    recognized that as-applied constitutional claims might prevail if vested rights were
    affected by application of the 2003 amendments. This is the as-applied challenge we
    anticipated in Lummi.
    The appellants here 4 assert due process and other challenges to the 2003
    legislation as applied to water right certificates issued to Washington State University
    (WSU) in the 1960s for domestic and community domestic and stock water uses.
    Appellants assert that the 2003 legislation was applied to redefine the legal character of
    these water rights, transforming them into valid rights for municipal water supply
    purposes. Appellants argue that absent application of the 2003 legislation, these water
    rights were subject to statutory relinquishment5 under chapter 90.14 RCW and had,
    indeed, been relinquished, in whole or in part.
    I would reverse and remand this case to the Washington Pollution Control
    Hearings Board (Board) for reconsideration of appellants' claims of statutory

    It is undisputed that long-term declining water levels in the Grand Ronde Aquifer threaten all of

    Relevant Facts
    In 2004, WSU applied to the Washington Department of Ecology for changes to
    all of its existing water rights that WSU holds to provide water to its primary campus.
    WSU is the state's land grant institution of higher education, with its primary campus
    located within the limits of the city of Pullman, Washington. WSU operates its own
    water system that   ser~es   the campus. All of the water that is supplied is withdrawn from
    WSU's wells, except for an emergency intertie with the city of Pullman.
    WSU's applications in effect sought to permit water authorized under any of its
    water rights to be withdrawn from any of its wells. The goal was to bring the university's
    water rights into conformance with the in-fact consolidation of these rights that had
    occurred over time. Between 1935 and 1983, WSU was issued four water rights and it
    registered three claims for groundwater rights obtained prior to enactment of the
    groundwater code in 1945. WSU has drilled and operated eight wells. Eventually, WSU
    was pumping water from the wells into one integrated water system divided into two
    distribution zones. Also, as time has passed, WSU has consolidated its well operations,
    shifting pumping away from older wells as it brought new wells online. WSU never
    obtained authorization to use its water rights in an integrated system, and the university's
    withdrawal of water from each of the individual wells has not matched the quantity of
    4
                                                     
    No. 88317-3
    Madsen, C.J., dissenting
    water authorized to be withdrawn from the well, either historically or at present. In
    recent years, WSU has withdrawn water through only three of its wells: Wells 6, 7, and
    8.
    In the early 2000's, Gary Wells, an engineer in WSU's facilities operations
    division, began working on a water rights change proposal because WSU's system was
    aging and largely dependent on one well, Well 7. Wells was concerned about being able
    to provide sufficient water for the campus if Well 7 became inoperable.
    WSU provided notice of its applications to change its water rights, and Scott
    Cornelius and the Palouse Water Conservation Network objected to the change requests.
    In 2006, Ecology approved the proposed amendments for six of the rights but determined
    that one of the claims, Claim No. 098524, was invalid. As to the other water rights,
    Ecology applied the legislation enacted in 2003 that addresses municipal water supplies
    and suppliers. 6 Ecology found that all ofWSU's remaining claimed rights are for
    "municipal water supply purposes" as defined by the new statutory provisions.
    Appellants appealed to the Board, which resolved most of the issues against
    appellants on summary judgment. The Board decided that it lacked jurisdiction to
    address appellants' constitutional challenges, characterizing them as tantamount to facial
    challenges. Following a hearing on the three issues not decided on summary judgment,
    the Board issued its final order in April2008 and subsequently denied reconsideration.

    The parties refer to the body of 2003 legislation concerning municipal water as the "Municipal

    As the Board found, groundwater is the primary source of water for WSU, the city
    of Pullman, the city of Moscow, Idaho, the University of Idaho, and the surrounding
    areas in Whitman County, Washington, and Latah County, Idaho. In the 1990s, the two
    universities and the two cities endorsed individual plans to reduce impacts of their
    groundwater withdrawals. WSU's water use has been below annual targets, and in 2005,
    WSU' s water use was below the amount used in 1992, when efforts began to limit
    pump mg.
    WSU withdraws its water from the Grande Ronde Aquifer. It is undisputed, and
    the Board found, that long-term declining water levels in the Grand Ronde Aquifer
    threaten all of the water users in the basin if not addressed adequately. At the present
    time, the only recognized way to slow or reverse the aquifer decline is to reduce the
    withdrawal of water from it.
    Appellants appealed the Board's decision to Whitman County Superior Court,
    which affirmed. When appellants' appealed to the Court of Appeals, Division Three
    certified the case to this court, which we accepted.
    Standard of Review
    The Washington Administrative Procedure Act (APA), chapter 34.05 RCW,
    governs proceedings before the Board. An appellate court reviewing a decision of the
    Board sits in the same position as the superior court and applies RCW 34.05.570's

    Relinquishment
    On August 1, 1962, WSU was issued Certificate 5070-A (Well4) for domestic
    supply for WSU, with the right quantified at 1500 gallons per minute and 2,260 acre-feet
    per year. On May 27, 1963, WSU was issued Certificate 5072-A (WellS) for community
    domestic supply and stock water, quantified at 500 gallons per minute and 720 acre-feet
    per year. Appellants maintain that these rights were subject to statutory relinquishment
    and were relinquished in whole or in part because of nonuse over extended periods of
    time.
    Ecology determined, however, (1) that these rights are for municipal water supply
    purposes according to the 2003 legislation that specifically defines "municipal water

    supply purposes," RCW 90.03.0 15(4); (2) that WSU is a "municipal water supplier" as
    defined, RCW 90.03.015(3); and (3) that each of its rights is for municipal supply
    purposes according to present beneficial use. 7 Water rights for municipal water purposes
    are excepted from relinquishment pursuant to RCW 90.14.140(2)(d). 8 Appellants
    maintain, however, that applying the 2003 definition in RCW 90.03.015(4) to redefine
    the rights under Certificates 5070-A and 5072-A as rights for municipal water supply
    purposes, with the result that the relinquishment statutes do not apply, violates due
    process. I agree with appellants.
    Under the relinquishment statutes, any water right holder who, without cause,
    voluntarily fails to beneficially use all or any portion of the water right for a period of

    RCW 90.03.015(3) and (4) provide in part:
    The definitions in this section apply throughout this chapter unless the context
    clearly requires otherwise.
    (3) "Municipal water supplier" means an entity that supplies water for
    municipal water supply purposes.
    (4) "Municipal water supply purposes" means a beneficial use of water:
    (a) For residential purposes through fifteen or more residential service
    connections or for providing residential use of water for a nonresidential
    population that is, on average, at least twenty-five people for at least sixty days a
    year . . . . If water is beneficially used under a water right for the purposes listed
    in (a) ... of this subsection, any other beneficial use of water under the right
    generally associated with the use of water within a municipality is also for
    "municipal water supply purposes," including, but not limited to, beneficial use
    for commercial, industrial, irrigation of parks and open spaces, institutional,
    landscaping, fire flow, water system maintenance and repair, or related purposes.

    RCW 90.14.140 sets out sufficient cause for nonuse of a water right to except the right from
    relinquishment. RCW 90.14.140 states in part:

    during some years, but this use either ceased entirely or dropped precipitously during a
    period of at least five successive years, and in neither case was the right used to the extent
    of the certificated amount of water.
    Although WSU was authorized to withdraw up to 2,260 acre-feet per year under
    water right Certificate 5070-A from Well4, it pumped a maximum of only 1090 acre-
    feet, in 1969, and from 1989 through 2002, it pumped 740 acre-feet per year or less.

    Id.
    WSU claims to have switched to pumping water under these rights from
    unauthorized wells, but the table does not show this. It does not show increased
    withdrawals from other wells in sufficient quantity to account for its decreased pumping
    from Wells 4 and 5. Further, the rights WSU held, to withdraw from its wells other than
    Wells 4 and 5, were rights to amounts that were never fully withdrawn from the other
    wells, and it is difficult to see how water was withdrawn under Certificates 5070-A and
    5072-A from WSU's other wells when the full amount of water under the rights
    pertaining to the other wells was never withdrawn. Moreover, WSU agrees that it
    reduced its water use over time. There is no dispute that WSU has never beneficially
    used the quantities of water authorized under its water rights.

    While there are questions remaining about the total amount that was not used
    under the water right certificates, there appears to be no question that WSU did not use
    the full extent of its water rights under Certificates 5070-A and 5072-A for periods of at
    least five successive years.
    WSU contends that the relevant question for purposes of relinquishment is
    whether a right is "claimed" for municipal purposes and not whether it is "issued" for
    municipal purposes, relying on the term "claimed" in RCW 90.14.140(2)(d). In full,
    RCW 90.14.140(2)(d) says that "[n]otwithstanding any other provisions ofRCW
    90.14.130 through 90.14.180, there shall be no relinquishment of any water right ... [i]f
    such right is claimed for municipal water supply purposes under chapter 90.03 RCW."
    (Emphasis added.)
    The complete language of the exception shows what is meant. The exception
    applies to municipal water rights that have been acquired under the provisions in chapter
    90.03 RCW for obtaining a right to use water for municipal water supply purposes. 10
    Here, the two certificates of water rights show on their face that when they were
    acquired, it was for domestic and community domestic and stock water uses, not
    municipal uses.
    The fact that WSU apparently combined the water from its wells into a
    consolidated system did not alter the purposes of the water rights it held during the time
    period that relinquishment occurred. Water rights issued for domestic uses were not

    water rights for municipal uses. The definitions section of chapter 90.14 RCW, where
    the relinquishment statutes are found, draws a distinction between domestic and
    municipal uses of water in RCW 90.14.031. The statute defines "beneficial use" to
    include "use for domestic water [and] municipal." RCW 90.14.031. RCW
    90.14.140(2)( d), .the exception itself, applies to water rights for "municipal water supply
    purposes" and does not mention or imply that water rights for domestic uses qualify for
    the exception.
    The distinction between domestic uses and municipal uses is reflected in a large
    body of law in this state and other western states, confirming that the distinction between
    domestic use and municipal use has long been an elemental concept in water law. And
    while municipal use might include water for residential, domestic use, the converse has
    not been true. A water right issued for domestic use was not a water right that
    encompassed municipal use.
    In our state, the distinction continues to be explicitly recognized in numerous
    statutes aside from chapter 90.14 RCW. 11 In addition, case law in this state has also long

    A more detailed discussion of municipal water uses follows:
    Within the scope of public water supply or municipal water supply, almost the full
    range of uses exists: residential (domestic), governmental (city lands and
    buildings, institutions, fire protection, sewers), commercial, and industrial. The
    only two primary uses generally not mentioned are agriculture and mining,
    although mineral processing could come within industrial use, and mining less
    clearly within industrial use. Often, early commercial establishments were in the

    As can be seen, municipal uses may include uses that fall within the domestic uses
    category, but a water right issued for domestic use did not allow the user to put the water
    to any and all municipal uses. For example, the holder of a water right for domestic uses
    would not have been entitled to use the water under the right for a public golf course,
    although the holder of a water right for municipal uses could do so. In addition, as the
    preference lists adopted by statute in some of the western states reveal, domestic use has
    traditionally been regarded as superior in importance.
    In sum, there is and has been a basic legal difference between water rights granted
    for municipal use and water rights granted for domestic use. I recognize that on their
    face the 2003 statutory provisions concerning municipal water alter the distinction insofar
    as a particular right now falls under the definition for "municipal water supply" purposes.
    But here the issue is whether statutory relinquishment occurred prior to these statutes
    being enacted, and throughout that time the distinction between municipal uses and
    domestic uses prevailed.
    WSU maintains, however, that despite the purposes of use stated on the water
    rights certificates, the two rights were in fact granted for municipal uses. For example,
    same structure as the residence. Water was used in the commercial establishment
    for the same primary uses as in residences-human consumption and sanitation.
    At some point cities became industrialized, like Pittsburgh, known for
    steelmaking. Thus municipal and industrial were one because industry was
    located in urban areas. Add to these governmental uses, such as fire prevention,
    park maintenance, street washing, and public institutions, and the picture is
    complete. Today cities may consist largely of residential and commercial
    habitations and government structures.

    WSU relies on language in its application for the right to appropriate water rather than
    the purpose actually stated on Certificate 5072-A (Well5) for community domestic
    supply and stock water. The difficulty is that an applicant could state any number or type
    of possible proposed uses on an application to appropriate water. What matters is the use
    for which the water right is granted. Indeed, when a water right certificate is granted for
    an express purpose that is different from what was requested, it is significant evidence
    that the requested purpose was rejected.
    Moreover, great uncertainty would be introduced into certificated water rights if
    they can be disregarded in favor of after-the-fact, case-by-case inquiries into the purpose
    of use that the applicant attempted to obtain. Absent a showing that the issuing agency
    meant to grant a certificated water right for municipal uses but inadvertently failed to do
    so, i.e., a scrivener's error or comparable mistake, the purpose of use stated on the
    certificate must control. Cf, e.g., RCW 90.03.330(2) (providing for adjustment of
    certificates if ministerial errors are discovered).
    WSU additionally points out that its application showed an expectation of
    increasing future emollment and points out that the stated quantity of water right in
    Certificate 5072-A was unnecessary to serve the then-existing population. It should go
    without saying, after our decision in Theodoratus, that Ecology and its predecessor have
    not always issued water right certificates in accordance with existing statutes. 14 But
    whether the agency had authority to issue a right for domestic uses in an amount to

    satisfy far-in-the-future predicted expansion is not a matter that must be decided here.
    The fact is that the two rights at issue are certificated water rights for domestic and
    community domestic and stock water uses that have never, in the 50 or so years since
    issuance, been used in amounts anywhere close to the amounts stated on the certificates.
    The applicable relinquishment statute provides that
    [a]ny person hereafter entitled to divert or withdraw waters of the state
    through an appropriation authorized under RCW 90.03.330, 90.44.080, or
    90.44.090 ... who voluntarily fails, without sufficient cause, to beneficially
    use all or any part of said right to withdraw for any period of five
    successive years shall relinquish such right or portion thereof.
    RCW 90.14.180. Nothing in this statute requires that unused water under a certificated
    right has to first be put to use before the right is subject to relinquishment.
    Appellants have presented evidence that WSU relinquished any right it may have
    had to use the stated amount of water long before 2003, and WSU does not adequately
    rebut the evidence.
    Finally, it should be noted that in other administrative review cases, the Board has
    addressed relinquishment in connection with water rights that were issued for community
    domestic purposes, showing that the Board has not equated community domestic use to
    municipal use. Olga Water Users, Inc. v. Dep't of Ecology, No. 08-123, Order Granting

    Due Process
    The rights under Certificates 5070-A and 5072-A were held as rights to withdraw
    water for domestic and community domestic and stock water uses. But for Ecology's and
    the Board's determinations that the 2003 legislation changed their character
    retrospectively, these rights were not rights to use water for municipal water supply uses
    and they were subject to relinquishment. This being so, I turn to appellants'
    constitutional due process claim.
    Appellants contend that the Board's application of the 2003 definition of
    "municipal water supply," 15 with the result that water rights in Certificates 5070-A and
    5072-A were not subject to relinquishment despite extended periods of nonuse prior to
    2003, violates due process. Appellants appropriately begin with the court's decision in
    15
    In upholding Ecology's detenninations that the 2003 definition of"municipal water supply
    purposes" applies, the Board concluded that whether water rights are for "municipal water
    supply purposes" is determined at the time the right is characterized because the legislature used
    language defining "municipal water supply purposes" in the "present tense," i.e., "means a
    beneficial use ofwater." RCW 90.03.015(4) (emphasis added). Definitions in statutes
    frequently begin with "'X' means .... " I do not agree that this shows legislative intent that the
    definition applies to revive rights lost to relinquishment before the 2003 legislation was enacted.

    Appellants also argue that consolidation of WSU' s water rights in their certificated
    amounts will increase WSU's access to and ability to pump water from the aquifer. 18 At
    least to the extent WSU has relinquished part of its rights, they are correct. Appellants
    also argue that the Board's application of the 2003 laws pertaining to municipal water
    supply purposes effectively moved Cornelius's junior right farther down the line, and that
    they were denied the ability to mount a defense because the Board's application of the
    2003 definition of "municipal water supply purposes" meant evidence they submitted of
    relinquishment was entirely disregarded.
    Appellants have shown that the Board's application of the 2003 legislation
    violated due process. Unlike the facial challenge in Lummi, 170 Wn.2d at 267, here
    appellants establish that individual right holder Scott Cornelius's reasonable expectation
    of enjoyment of his water rights is impaired in violation of due process by the Board's
    application of the 2003 legislation, which effectively bars consideration of his evidence
    showing relinquishment prior to 2003. Due process requires that in the consideration of
    18
    Significantly, it is undisputed that the Grand Ronde Aquifer, from which individual plaintiff
    Cornelius and WSU obtain their water, is being pumped at a rate greater than the recharge rate.
    The Board determined, as all parties agree, that declining water levels in the aquifer threaten all
    of the users in the basin. Aquifer levels have declined an average 100 feet since measurements
    began in the 1930's. Individual appellant Scott Cornelius has documented a drop of 12.5 feet
    over 15 years in his private, domestic well.
    The Board's 2008 final order stated that "[t]he extent and availability of groundwater
    resources in the GRA [Grande Ronde Aquifer] are poorly known, due in part to a lack of precise
    information about the aquifer's rate of recharge. It is therefore impossible to predict with any
    degree of certainty how long the water in the GRA will last." Findings of Fact, Conclusions of
    Law & Order, No. 06-099, at 19-22 (Pollution Control Hr'gs Bd. Apr. 17, 2008) (4 AR Doc. 89).
    Pumping water in the area exceeds the aquifer's recharge and increases in the aggregate pumping
    in the Pullman-Moscow region "will necessarily cause water-level declines within the aquifer."

    I disagree with the majority's view that to reach this conclusion would require us
    to overrule Lummi and invalidate RCW 90.03.560. Majority at 13-14. Both contentions
    are incorrect. In Lummi, we acknowledged that the 2003 amendments applied to and
    confirmed "existing" water rights and that the amendments did not resurrect any
    relinquished rights. 170 Wn.2d at 263, 264, 268. Similarly, RCW 90.03.560 clearly
    applies to existing rights, that is, rights that have not been relinquished. 20

    I again disagree with the majority's view that "[i]fwe ruled for Cornelius, Ecology would

    door open for the 'as applied challenge presented here. Moreover, as discussed above, RCW
    90.03.560 may be applied to relabel existing rights, that is, water rights that have been fully
    utilized, put to beneficial use, and thus have not been statutorily relinquished.

    RCW 90.03.560 provides as follows:
    When requested by a municipal water supplier or when processing a change or
    amendment to the right, the department shall amend the water right documents
    and related records to ensure that water rights that are for municipal water supply
    purposes, as defined in RCW 90.03.015, are correctly identified as being for
    municipal water supply purposes. This section authorizes a water right or portion
    of a water right held or acquired by a municipal water supplier that is for
    municipal water supply purposes as defined in RCW 90.03.015 to be identified as
    being a water right for municipal water supply purposes. However, it does not
    authorize any other water right or other portion of a right held or acquired by a
    municipal water supplier to be so identified without the approval of a change or
    transfer of the right or portion of the right for such a purpose.

    and 1963 Ecology had no reason to be precise about distinguishing between municipal
    and domestic uses, stating that "Ecology could have issued domestic supply certificates
    to entities that were functionally municipal and vice versa." !d.
    I disagree. As discussed at length above, the distinction between domestic use and
    municipal use is a long-standing fixture of water law in the west. Under the statutory
    scheme, designated water rights may not be so easily disregarded. Although the 2003
    amendments resolved a particular labeling problem regarding existing water rights
    utilized for municipal purposes, that circumstance is not present here. As we have
    explained, if a user has met application requirements under RCW 90.03.290, Ecology
    will issue a water rights permit "'stating the amount of water to which the applicant shall
    be entitled and the beneficial use or uses to which it may be applied."' Theodoratus, 135
    Wn.2d at 591 (quoting RCW 90.03.290(3)). Thereafter, a "final certificate of water right
    will be issued upon a showing that the appropriation has been perfected." !d. at 592. In
    Theodoratus, we held that "a water right must be based on actual application of water to
    beneficial use and not upon system capacity." !d. "'An appropriated water right is
    established and maintained by the purposeful application of a given quantity of water to a

    relinquished." Theodoratus, 135 Wn.2d at 594-95 (citing RCW 90.14.130-.180); see also
    Lummi, 170 Wn.2d at 251-52. "The failure 'to beneficially use all or any part' of the
    right for five years, without sufficient cause, 'shall r~linquish' the right in whole or in

    Lummi, 170 Wn.2d at 251-52. "We will not construe the statutory scheme in a way
    which renders [the] provisions of the relinquishment statutes meaningless." Theodoratus,

    purports to apply Lummi, but as noted we recognized there that the 2003 amendments do
    not resurrect relinquished rights. 170 Wn.2d at 268.
    The fact that the legislature waited until 2003 to formally define "municipal water
    supply purposes" does not alter the fact that the water right designation for domestic use
    appearing in the 1962 and 1963 certificates did not include municipal use, such domestic
    use was subject to relinquishment, and was so relinquished due to nonuse long before the
    2003 amendments issued. "Under RCW 90.14.180, a person who holds a water right and

    In my view, this court must remand the question of the extent to which WSU
    relinquished water rights under Certificates 5070-A and 5072-A. The relinquished
    portions of these rights cannot be recharacterized as rights for municipal uses; to do so
    under the circumstances violates due process. To the extent these rights have been
    relinquished, they are not eligible for amendment.
    Conclusion
    Water rights granted in the 1960's for domestic uses was not a water right granted
    for municipal use. Accordingly, the exception to statutory relinquishment that exists for
    21
    This result does not render RCW 90.03.560 superfluous, as the majority contends. The statute
    may be properly applied to the appropriate circumstances. For instance, had WSU fully utilized
    the water allocated under Certificates 5070-A and 5072-A since the mid-1960s without lapse and
    broadened the use of such water to include municipal uses, then there would be no
    relinquishment and WSU's change application could be properly processed under RCW
    90.03.560. But that is not the circumstance here, and RCW 90.03.560 is not applicable under the
    facts of this case. Cf. Pub. Utility Dist. No. 1, 146 Wn.2d at 798 ("[I]n order to determine
    whether a change application may be granted under RCW 90.03.380, Ecology must tentatively
    quantify the right in order to determine whether the right qualifies for a change. If the right has
    been extinguished through relinquishment or abandonment, it is not subject to a certificate of
    change." (citation omitted)).

    municipal water rights did not apply to these rights during the period of time that
    appellants assert they were lost for nonuse. The rights that WSU held for domestic uses
    were subject to statutory relinquishment.
    The appeilants have submitted sufficient evidence to show nonuse, in whole or in
    part, of groundwater rights under   C~rtificates   5070-A and 5072-A, and as we noted in
    Lummi, the 2003 amendments do not resurrect relinquished rights. 170 Wn.2d at 268.
    Here, appellants have established a due process violation because vested rights
    were impaired by the Board's application of the 2003 legislation governing municipal
    water uses to WSU's water rights, which were issued for domestic uses and community
    domestic and stock water uses and had long since been subject to relinquishment due to
    nonuse.
    This court should reverse the Board's determination that the water rights under
    Certificates 5070-A and 5072-A were not relinquished in whole or in part and remand for
    a determination of the extent to which these rights were relinquished.
