    Washington’s designation as “The Evergreen State” really only
    applies to half of the state. “Irrigation in the Pacific Northwest,”
    Washington State University Extension (2019).
    Washington water law allows one holding a water right to change the location
    of the usage of the water through a process administered by the Washington State
    Department of Ecology (Ecology). As part of the application process, the water right
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    holder must calculate its annual consumptive quantity (ACQ) of water as defined by
    RCW 90.03.380(1). In this appeal, we hold, based on RCW 90.03.380(1), that the
    applicant must calculate anew its annual consumptive quantity with each change
    application no matter if Ecology recently approved an earlier change. We thus reverse the
    superior court.
    FACTS
    Despite a large record on appeal, the parties severely limit the facts outlined in
    their briefs, perhaps because of the constrained questions on appeal. Loyal Pig, LLC
    holds a water right certificate granted in 1970 to apply water to Franklin County
    farmland. The law limits a water right to an amount of use per year, a rate of flow, a point
    of diversion, and a location of application. Nevertheless, the water right holder may apply
    for a change in the site of diversion, the place of application, or both.
    In 2014, Loyal Pig’s predecessor applied to the Benton County Water Conservancy
    Board (Benton County board) for a change in location of the diversion of and a change in
    the site of the application of a portion of the water right. When reviewing the 2014
    change application, the Benton County board, as required by law, calculated the annual
    consumptive quantity of water on the Franklin County farmland. The calculation would
    limit the amount of water that Loyal Pig could apply on the new location of application.
    2
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    The law calculates the ACQ by averaging the most recent five-year period of continuous
    beneficial water consumption used by the irrigator. The Benton County board calculated
    the ACQ with average water use from 2009 to 2013, the five most recent years before the
    2014 application for change. Neither party identifies the amount calculated by the Benton
    County board. The Department of Ecology reviewed the Benton County board’s
    decision, as required by law, and approved the change in the water right certificate.
    Because of a lower use of water, during 2009 to 2013, the change limited the amount of
    the water right from its original amount in 1970.
    In January 2017, Loyal Pig submitted another application with the Franklin County
    Water Conservancy Board (Franklin County board) for an additional change in diversion
    location and place of application for the water right. In May 2017, the Franklin County
    board issued its decision approving the January application. In doing so, the board
    adopted the 2014 annual consumptive quantity amount, rather than calculating a new
    amount based on the years 2012 to 2016. The Franklin County board reasoned that it
    need not perform a new calculation since Loyal Pig filed the 2017 application within five
    years of the 2014 calculation. We do not know if the ACQ, based on years 2012 to 2016,
    would differ from any ACQ calculated for years 2009 to 2013. No party has performed
    3
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    this calculation. The Department of Ecology is unable to perform the calculation because
    Loyal Pig refuses to provide the records needed.
    The Department of Ecology reversed the Franklin County Water Conservancy
    Board’s decision because the Franklin County board failed to perform a new annual
    consumptive quantity calculation for years 2012 to 2016. Loyal Pig, together with the
    Columbia Snake River Irrigators Association, an association of Mid-Columbia irrigating
    growers, appealed, to the Washington State Pollution Control Hearings Board (PCHB),
    Ecology’s reversal of the Franklin County board’s approval of the 2017 change
    application. We refer to the two challengers collectively as Loyal Pig.
    Before the Pollution Control Hearings Board, Loyal Pig argued that the
    Department of Ecology should have utilized the annual consumptive quantity from the
    2014 change application for the 2017 application for numerous reasons. First, the
    principle of res judicata precluded a new calculation. Second, a governing statute affords
    a five-year grace period for loss of water rights, and Ecology should apply this grace
    period when a water right holder applies for a second change in use within five years of
    the first application. Third, an Ecology policy, POL 1120, simplified the determination
    for an application change, and requiring a new calculation of the ACQ for each change
    would thwart this policy. Fourth, irrigators in the Columbia Basin have relied on
    4
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    Ecology’s application of the grace period when a water right holder applied for a second
    change within five years of a previous calculation of the ACQ.
    Before the Pollution Control Hearings Board, the Department of Ecology argued
    that RCW 90.03.380 requires a full formal annual consumptive quantity calculation from
    the most recent five-year period no matter if the applicant for a change obtained a change
    approval within the last five years. For the 2017 change application, according to
    Ecology’s interpretation of the statute, the ACQ would comprise water usage during
    2014-2016 in addition to the previously calculated amounts for 2012 and 2013.
    Both Loyal Pig and the Department of Ecology filed motions for summary
    judgment before the Pollution Control Hearings Board. In support of its motion, Loyal
    Pig submitted a declaration of Mark Nielson, clerk and alternate member of the Franklin
    County Water Conservancy Board, and Darryll Olsen, Columbia Snake River Irrigators
    Association board representative and member of the Benton County Water Conservancy
    Board. Mark Nielson averred that he attended “at least one presentation in which
    Ecology staff emphasized that conservancy boards, like Ecology itself, are entitled to rely
    upon prior decisions through the judicial doctrine of res judicata.” Clerk’s Papers (CP) at
    499.
    5
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    In his PCHB declaration, Darryll Olsen averred that “[t]he community of water law
    practitioners has for many decades long relied upon the five-year grace period in
    assessing water rights and change/transfer applications.” CP at 601. Olsen’s declaration
    attached a legal memorandum from attorney Tom McDonald. McDonald opined that the
    Franklin County Water Conservancy Board could use the 2014 ACQ analysis for the
    2017 application as “[u]nder the law of administrative res judicata and collateral estoppel,
    courts will preclude the readjudication of claims and issues to enforce an administrative
    agency decision.” CP at 186. In his confidential communication, McDonald also
    observed that, under Ecology POL 1120, Ecology may conduct a simplified tentative
    determination that would not require an ACQ analysis when an application is submitted
    within five years of a previously approved application.
    In support of its motion, the Department of Ecology submitted declarations from
    employees Herman Spangle and Keith Stoffel. Spangle, an environmental specialist in
    Ecology’s Eastern Regional Office Water Resources Program, reviewed Loyal Pig’s
    change application for 2017. Spangle then determined an ACQ analysis would be
    required for the 2017 application because the proposed change would add other irrigated
    acres to the water right. Spangle averred that he concluded, along with Keith Stoffel, the
    6
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    section manager of Water Resources, that Ecology needed to review irrigation records for
    years 2014 to 2016. Stoffel’s own declaration corroborated Spangle’s testimony.
    The Pollution Control Hearings Board granted the Department of Ecology’s
    motion for summary judgment.
    PROCEDURE
    Loyal Pig appealed to the Benton County Superior Court. Before the superior
    court, Loyal Pig moved for summary judgment on three grounds. First, Loyal Pig argued
    that language in chapter 90.14 RCW provided a five-year grace period, during which the
    legislature intended to protect a water user from relinquishment of his or her water right.
    Second, Loyal Pig contended that a conservancy board should be permitted to rely on its
    prior decisions under the doctrine of administrative res judicata. Third, Loyal Pig
    maintained that Ecology violated the Administrative Procedure Act, chapter 34.05 RCW,
    when it insisted on calculating a new annual consumptive quantity for the 2017 change
    application, because this insistence effectively adopted a regulation without following the
    administrative rulemaking process.
    In support of its summary judgment motion, Loyal Pig submitted the declaration of
    Timothy Reierson and another declaration of Darryll Olsen. Timothy Reierson, a licensed
    professional engineer and a water rights consultant, declared that, from 1989 to 1996, he
    7
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    worked at the Department of Ecology, during which time he prepared reports
    recommending approval, denial, or mediation of complex and politically sensitive water
    right applications and change or transfer applications. Reierson did not testify to any
    percipient knowledge that Ecology previously adopted or followed a policy or practice
    that allowed an applicant for a second change in the water right a five-year grace period
    for the calculation of an annual consumptive quantity. Nevertheless, he averred that any
    failure to follow such a policy would constitute a “new approach.” CP at 460. Reierson
    noted that a grower who rotates crops on its land will fluctuate from year to year in the
    amount of water used.
    In Darryll Olsen’s declaration, Olsen avowed that the Department of Ecology, by
    reason of its rejection of the 2017 change application, informally adopted a new agency
    order, directive, or regulation of general applicability that refused to implement a
    longstanding five-year grace period against relinquishment of water rights. Olsen
    highlighted Ecology’s POL 1120’s promotion of a simplified procedure when forfeiture
    of water is not an issue. Olsen observed that, as early as 2009, Ecology moved away from
    this well-established procedure, taking the position that no grace period existed.
    The Department of Ecology cross moved for summary judgment on Loyal Pig’s
    claim of abuse of rulemaking authority. In support, Ecology submitted the declaration of
    8
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    Mark Schuppe, current Department of Ecology operations manager for the Office of
    Columbia River. Schuppe stated that he had extensive experience in water rights
    permitting and has worked with POL 1120 since its adoption. Schuppe declared:
    [w]hile this policy does allow for ‘simplified tentative
    determinations’ in some circumstances, I understand this to be within the
    discretion of a permit writer and approving manager. I would not interpret
    this policy to bar the review of ‘annual consumptive quantity’ (ACQ) if it
    was performed within five years of a previous ACQ analysis.
    CP at 529. Schuppe elaborated that another policy, POL 1210, did not bar a new ACQ
    analysis with a second application:
    I have not, now or in the past, interpreted POL 1210 to bar an ACQ
    analysis within five years of a previous analysis, and I am not aware of
    anyone else at Ecology who has done so.
    CP at 529.
    The declaration of Mark Schuppe attached POL 1120, as well as POL 1210. POL
    1210 outlines the procedures that the Department of Ecology employs when reviewing
    water right change applications pursuant to RCW 90.03.380(1) that seek to irrigate
    additional acreage. Unlike POL 1120, POL 1210 does not mention a simplified tentative
    policy.
    The Department of Ecology submitted a motion to strike portions of the
    declarations of Darryll Olsen, Timothy Reierson, and Mark Nielson. Ecology argued that
    9
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    sections of the declarations were inadmissible hearsay and contained inadmissible legal
    opinions. The superior court refused to strike the entirety of the three declarations.
    Nevertheless, the court agreed that the declarations contained extensive legal opinions,
    and the court stated it would ignore the opinions.
    The superior court reversed the Pollution Control Hearings Board and ruled that
    the Department of Ecology may not require a new annual consumptive quantity
    calculation when a water right holder applies for a second change in the water right
    within a five-year window. The superior court also ruled that Ecology abused its
    rulemaking authority. The court issued a permanent injunction that bars Ecology from
    requiring sequential ACQ calculations unless Ecology engages in the formal rulemaking
    process.
    LAW AND ANALYSIS
    RCW 90.03.380(1) and Two ACQs
    This appeal raises the principal question of whether, under RCW 90.03.380, the
    Department of Ecology may insist that a water right holder calculate anew its annual
    consumptive quantity when Ecology, within the past five years, already calculated the
    holder’s ACQ because of an earlier application for change.

    Although we do not deem the rules of review important in this appeal’s context,
    we recite those obligatory rules. This appeal arises from a Pollution Control Hearings
    Board (PCHB) decision after superior court review. The Administrative Procedure Act,
    chapter 34.05 RCW, governs appeals from the PCHB. Public Utility District No. 1 of
    Clark County v. Pollution Control Hearings Board, 
    137 Wash. App. 150
    , 156-57, 
    151 P.3d 1067
    (2007). The Court of Appeals reviews the PCHB’s decision from the same vantage
    as the superior court. Skagit County v. Skagit Hill Recycling, Inc., 
    162 Wash. App. 308
    ,
    317, 
    253 P.3d 1135
    (2011). This court may find the PCHB erred if the board erroneously
    interpreted or misapplied the law. Public Utility District No. 1 of Clark County v.
    Pollution Control Hearings 
    Board, 137 Wash. App. at 157
    . The party asserting invalidity
    bears the burden of demonstrating the invalidity of agency action. RCW 34.05.570(1)(a).
    We consider the appeal to raise a purely legal question.
    RCW 90.03.380(1) governs our decision. The laborious statute reads, in relevant
    part:
    The right to the use of water which has been applied to a beneficial
    use in the state shall be and remain appurtenant to the land or place upon
    which the same is used: PROVIDED, HOWEVER, That the right may be
    transferred to another or to others and become appurtenant to any other land
    or place of use without loss of priority of right theretofore established if
    such change can be made without detriment or injury to existing rights.
    The point of diversion of water for beneficial use or the purpose of use may
    be changed, if such change can be made without detriment or injury to
    11
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    existing rights. A change in the place of use, point of diversion, and/or
    purpose of use of a water right to enable irrigation of additional acreage or
    the addition of new uses may be permitted if such change results in no
    increase in the annual consumptive quantity of water used under the water
    right. For purposes of this section, “annual consumptive quantity” means
    the estimated or actual annual amount of water diverted pursuant to the
    water right, reduced by the estimated annual amount of return flows,
    averaged over the two years of greatest use within the most recent five-year
    period of continuous beneficial use of the water right. Before any transfer
    of such right to use water or change of the point of diversion of water or
    change of purpose of use can be made, any person having an interest in the
    transfer or change, shall file a written application therefor with the
    department. . . . If it shall appear that such transfer or such change may be
    made without injury or detriment to existing rights, the department shall
    issue to the applicant a certificate in duplicate granting the right for such
    transfer or for such change of point of diversion or of use. . . . The time
    period that the water right was banked under RCW 90.92.070, in an
    approved local water plan created under RCW 90.92.090, or the water right
    was subject to an agreement to not divert under RCW 90.92.050 will not be
    included in the most recent five-year period of continuous beneficial use for
    the purpose of determining the annual consumptive quantity under this
    section. If the water right has not been used during the previous five years
    but the nonuse of which qualifies for one or more of the statutory good
    causes or exceptions to relinquishment in RCW 90.14.140 and 90.44.520,
    the period of nonuse is not included in the most recent five-year period of
    continuous beneficial use for purposes of determining the annual
    consumptive quantity of water under this section.
    (Emphasis added.)
    The Department of Ecology argues that the explicit language of RCW
    90.03.380(1) requires it to review the “most recent five year period” of water use to
    determine annual consumptive quantity before approving a water right owner’s
    12
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    application to change or transfer a water right, regardless of any earlier approved
    application. Loyal Pig astutely responds that Ecology’s interpretation of RCW
    90.03.380(1) places an irrigator at risk of premature relinquishment or reduction of its
    water right. Based on Ecology’s interpretation, if an irrigator submits an application
    within five years of having an ACQ previously calculated and a water transfer application
    approved, the irrigator would need to again explain nonuse or face relinquishment. Loyal
    Pig contends that the more appropriate interpretation of RCW 90.03.380(1) would allow
    the water right owner, once Ecology approves a water change application, to seek a
    further change within the “five year grace period” following the approval of its
    application and, during this five-year grace period, no subsequent calculation of water use
    should be required when the user’s farming practices have not changed. According to
    this contention, when Loyal Pig submitted its application for a change in water use in
    2017, the 2014 adjudication of the ACQ bound Ecology.
    We could exhaust paragraphs outlining principles of statutory construction, but we
    limit our discussion for now to two principal principles. Our ultimate objective is to
    ascertain and carry out the legislature’s intent. Gorre v. City of Tacoma, 
    184 Wash. 2d 30
    ,
    37, 
    357 P.3d 625
    (2015). When presented with clear language, we must assume the
    13
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    legislature meant exactly what it said and apply the statute as written. University of
    Washington v. City of Seattle, 
    188 Wash. 2d 823
    , 832, 
    399 P.3d 519
    (2017).
    We agree with the Department of Ecology that RCW 90.03.380(1) shows
    legislative intent to require a new annual consumptive quantity calculation with every
    application for a change in the water right certificate. The statute demands a review of
    the last five years of water consumption. The statute admits no exception when the
    applicant applied for a change in the water right during the last five years.
    Loyal Pig requests that we adopt the analysis of RCW 90.03.380(1) performed in
    legal opinions requested by water conservancy boards. Loyal Pig also asks us to embrace
    the rationale behind In Re Bugni, a discrete decision entered by the Yakima County
    Superior Court in the extensive Yakima River watershed adjudication of Department of
    Ecology v. Acquavella, No.77-2-01484-5 (Wash. Super. Ct. Oct. 12, 1977). Sidney P.
    Ottem, The General Adjudication of the Yakima River: Tributaries for the Twenty-First
    Century and a Changing Climate, 23 J. Envtl. & Litig. 275 (2008). We decline these
    requests because of the explicit language of RCW 90.03.380(1).
    Loyal Pig fears the Department of Ecology’s interpretation of RCW 90.03.380
    exposes growers to a partial relinquishment of a water right. Loyal Pig relatedly argues
    that Ecology’s interpretation of RCW 90.03.380 conflicts with the spirit behind RCW
    14
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    90.14.140, which shuns penalizing a water user for nonuse of water for sufficient reasons.
    To understand the fear, we provide some background to Washington water law.
    Washington’s water law, promulgated throughout the state’s history by statute and
    case law, follows the western American doctrine of water rights by appropriation rather
    than the eastern rule of riparian water rights. RCW 90.03.010; Cornelius v. Department
    of Ecology, 
    182 Wash. 2d 574
    , 586, 
    344 P.3d 199
    (2015). Under the appropriation system,
    the water right holder must put the water claimed under the right to beneficial use or it
    relinquishes the right. RCW 90.14.160; Department of Ecology v. Theodoratus, 
    135 Wash. 2d 582
    , 595, 
    957 P.2d 1241
    (1998). Washington law demands that a water right
    return to the state, under relinquishment statutes, to the extent that, without cause, the
    water right holder voluntarily fails to beneficially use all or any portion of the water right
    for a period of five successive years. RCW 90.14.130-.180; Department of Ecology v.
    Acquavella, 
    131 Wash. 2d 746
    , 758, 
    935 P.2d 595
    (1997).
    As well as being critical to establishing the existence of a water right, beneficial
    use establishes the quantity of that right. Crown West Realty, LLC v. Pollution Control
    Hearings Board, 
    7 Wash. App. 2d
    710, 733, 
    435 P.3d 288
    (2019), review denied, 
    193 Wash. 2d 1030
    , 
    447 P.3d 165
    (2019). A user acquires the right only to the quantity of water
    actually put to use with reasonable diligence. Cornelius v. Department of Ecology, 182
    15
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    Wn.2d at 586 (2015). If a water right holder fails to beneficially use any or all of its right
    for five successive years, the right holder loses all or a portion of the right unless it shows
    its nonuse falls under one of the narrow categories in RCW 90.14.140. Department of
    Ecology v. 
    Acquavella, 131 Wash. 2d at 758
    ; Cornelius v. Department of 
    Ecology, 182 Wash. 2d at 617
    .
    RCW 90.14.160 declares:
    Any person entitled to divert or withdraw waters of the state
    through any appropriation authorized by enactments of the legislature . . .
    who abandons the same, or who voluntarily fails, without sufficient cause,
    to beneficially use all or any part of said right to divert or withdraw for any
    period of five successive years after July 1, 1967, shall relinquish such right
    or portion thereof, and said right or portion thereof shall revert to the
    state.
    (Emphasis added.) In turn, RCW 90.14.140(1) defines “sufficient cause” in part as
    drought, service in the armed forces, operation of legal proceedings, federal law
    restricting water use, temporary reductions of need due to weather conditions, and
    temporary reduction of use due to a crop rotation.
    Loyal Pig sought changes in application of its water right in both 2014 and 2017.
    Although a water right certificate limits use of the right to a particular source and
    diversion location and to a discrete area of land, the water right holder may apply to the
    Department of Ecology to change the location of diversion or the situs of irrigation.

    RCW 90.03.380(1) authorizes this change or transfer. When a water right holder applies
    to amend its certificates or to change the manner or place of use of the water, Ecology

    at 720. RCW 90.03.380 impliedly grants Ecology the
    right to limit the extent of the change to the current annual consumptive quantity, which
    could be lower than the initial water right.
    The Department of Ecology and Loyal Pig disagree as to whether Ecology’s
    interpretation of RCW 90.03.380 could reduce the water right holder’s water right.
    We agree with Loyal Pig and share its concern about an unfair law. When Loyal Pig
    applied for the change in 2014, the Department of Ecology measured its annual
    consumptive quantity and thereafter limited its water right to that quantity. If Ecology
    measures the ACQ again in 2017, the calculation could arrive at a smaller sum than the
    2014 calculation. Use of a new ACQ could further reduce Loyal Pig’s water right.
    Agriculture in major sections of eastern Washington, particularly the Columbia
    River basin, lacks the rainfall to raise crops, and the region survives and thrives on
    irrigation water. Profitable production of most crops east of the Cascade Mountains
    17
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    demands irrigation. Alternating crops grown on the same land helps to preserve the land,
    but different crops require different sums of irrigation. Frequent changes in transfer
    diversion points and application sites, even within a five-year window of time,
    accommodate an efficient use of irrigation water from crop to crop and site to site. Under
    RCW 90.03.380(1), these frequent changes could penalize irrigators by reducing a water
    right. The current law also promotes excessive use of irrigation water in order to save
    water rights. We would welcome a change in the law.
    We observe that some statutes mitigate Loyal Pig’s and our concern. For example,
    the legislature has afforded at least two situations in which the Department of Ecology
    may ignore the most recent five-year period when a water right holder applies for a
    change. RCW 90.03.615 reads:
    For purposes of calculating annual consumptive quantity as defined
    under RCW 90.03.380(1), if, within the most recent five-year period, the
    water right has been in the trust water rights program under chapter 90.38
    or 90.42 RCW, or the nonuse of the water right has been excused from
    relinquishment under RCW 90.14.140, the department shall look to the most
    recent five-year period of continuous beneficial use preceding the date
    where the excuse for nonuse under RCW 90.14.140 was established and
    remained in effect.
    (Emphasis added.) We already mentioned RCW 90.14.140, which excuses a reduction in
    use by the water right holder due to drought, temporary reduction in water need, and the
    rotation of crops, among other reasons. We do not necessarily interpret one statute in
    18

    Loyal Pig, LLC v. Department of Ecology
    isolation, but rather find meaning from related provisions and the statutory scheme as a
    whole. State v. Engel, 
    166 Wash. 2d 572
    , 578, 
    210 P.3d 1007
    (2009). The language of
    RCW 90.03.615 bolsters our interpretation of RCW 90.03.380(1) in that the former
    statute also shows an intent to always measure the annual consumptive quantity based on
    the most recent five years unless limited exceptions apply.
    Because of some of the arguments asserted by Loyal Pig, the Department of
    Ecology addresses in its briefing whether the doctrines of collateral estoppel or res
    judicata prevent Ecology from asserting its view of RCW 90.03.380 in this appeal. In its
    brief, Loyal Pig agrees that it does not advocate application of res judicata or collateral
    estoppel in their traditional formats. Therefore, we do not address the application of the
    two doctrines.
    Loyal Pig does not directly assert that the Department of Ecology breached its POL
    1120 by requiring a new annual consumptive quantity with Loyal Pig’s 2017 change
    application. It subsumes any argument based on the policy with its request to bar Ecology
    from rulemaking. Therefore, we do the same.
    Rulemaking
    The Department of Ecology also asks that we reverse the superior court’s entry of
    an order enjoining Ecology’s implementation of its interpretation of RCW 90.03.380(1).
    19
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    The superior court deemed Ecology’s requirement of a new calculation for an annual
    consumptive quantity within a five-year window to constitute an adoption of a rule, such
    that Ecology needed to comply with rulemaking procedures. Ecology argues that an
    interpretation of an unambiguous statute by an administrative agency does not qualify as a
    rule. Loyal Pig responds that Ecology had previously afforded a five-year grace period
    with a second application for a change in water right and a change in this practice
    requires Ecology to undergo rulemaking procedures. Loyal Pig characterizes Ecology’s
    action as a shift in policy that requires rulemaking.
    Chapter 34.05 RCW, the Administrative Procedure Act, controls this question.
    RCW 34.05.010, the act’s definitions section, defines “rule” as:
    (16) “Rule” means any agency order, directive, or regulation of
    general applicability (a) the violation of which subjects a person to a penalty
    or administrative sanction; (b) which establishes, alters, or revokes any
    procedure, practice, or requirement relating to agency hearings; (c) which
    establishes, alters, or revokes any qualification or requirement relating to
    the enjoyment of benefits or privileges conferred by law. . . . The term
    includes the amendment or repeal of a prior rule, but does not include (i)
    statements concerning only the internal management of an agency and not
    affecting private rights or procedures available to the public.
    (Emphasis added.) Loyal Pig argues that the Department of Ecology’s new interpretation
    of RCW 90.03.380(1) and its abandonment of an earlier practice under one of its policy
    20
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    statements established a new qualification or requirement relating to the ability to transfer
    water rights, a benefit or privilege conferred by law.
    If any agency action meets the definition of a rule, it must follow rulemaking
    procedures. Failor’s Pharmacy v. Department of Social & Health Services, 
    125 Wash. 2d 488
    , 493, 
    886 P.2d 147
    (1994). RCW 34.05.570(2)(c) invalidates any rule adopted
    without the process.
    Our previous analysis and conclusion that RCW 90.03.380(1) demands a new
    calculation of the annual consumptive quantity on a second application for a water right
    change controls our response to Loyal Pig’s contention that the Department of Ecology
    engaged in rulemaking. Assuming any shift in Ecology’s policy or interpretation of the
    statute, the law demanded that shift because of the unambiguous nature of the statute.
    Just as this court must enforce a statute adopted by the legislature even against the court’s
    wishes, an administrative agency must also enforce a statute.
    An agency charged with the administration and enforcement of a statute may
    interpret ambiguities within the statutory language through the rulemaking process.

    152 Wash. 2d 584
    , 590, 
    99 P.3d 386
    (2004). But an agency is restricted in its interpretation of a statute and, by its
    rulemaking authority, may not amend or nullify a statute under the guise of interpretation.

    (1981).
    An administrative agency’s practice does not qualify as a rule, for purposes of the
    Administrative Procedure Act, when the practice does not create a new standard, formula,
    or requirement, but simply applies and interprets a statute. Budget Rent A Car Corp. v.
    Department of Licensing, 
    144 Wash. 2d 889
    , 896, 
    31 P.3d 1174
    (2001). An agency does
    not engage in rulemaking when following an explicit statute. Department of Ecology v.
    Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    , 19, 
    43 P.3d 4
    (2002). If the language of a
    provision of a statute which an agency is empowered to administer and enforce leaves no
    room for substantial debate over its meaning, an administrative rule reiterating the
    inevitable statutory consequence would not by definition constitute either a statutory
    interpretation or a statutory implementation that must be expressed by a rule promulgated
    pursuant to the Administrative Procedure Act. Equitable Life Mortgage & Realty
    Investors v. New Jersey Division of Taxation, 
    151 N.J. Super. 232
    , 
    376 A.2d 966
    , 971
    (N.J. Super. Ct. App. Div. 1977). Even if an agency announces a new statutory
    interpretation, the agency may do so through adjudication, and may give retroactive effect
    to the interpretation in the case in which the new interpretation is announced without
    22
    No. 36525-5-III

    rulemaking, because the agency is not really effecting a change in the law. Andrews v.
    District of Columbia Police & Firefighters Retirement & Relief Board, 
    991 A.2d 763
    ,
    771 (D.C. 2010).
    When an administrative agency adopts regulations that possess the force of law,
    the Administrative Procedure Act and fairness demand that the agency engage in a
    process that entails notice to the public and hearings so that the agency will hear and
    consider public input. Otherwise, administrative agencies will act as unelected
    legislatures. But when an administrative agency merely enforces a statute adopted by
    the legislature, the agency does not act in the nature of an unelected legislative body.
    The agency merely implements the will of the elected legislature.
    We deem Department of Ecology v. Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    (2002) controlling. Campbell & Gwinn, a subdivision developer, challenged Ecology’s
    interpretation of a statute that afforded an exemption from a groundwater permit for a
    well withdrawing less than 5,000 gallons per day. Campbell & Gwinn argued that
    Ecology changed its interpretation of the controlling statute and thereby altered
    qualifications for the enjoyment of a benefit. Therefore, according to Campbell & Gwinn,
    Ecology needed to engage in a rulemaking procedure. The developer also complained
    that an employee of Ecology earlier informed it that it did not need a groundwater permit
    23
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    when it proposed to use multiple wells collectively withdrawing over 5,000 gallons per
    day to serve a subdivision. The Supreme Court denied Campbell & Gwinn relief from
    Ecology’s application of its interpretation of the statute. Because Ecology merely
    interpreted a clear statute, it did not engage in rulemaking.
    Loyal Pig contends that the Department of Ecology’s action mirrors the
    Department of Ecology’s action in Hillis v. Department of Ecology, 
    131 Wash. 2d 373
    , 
    932 P.2d 139
    (1997). In Hillis, the Supreme Court ruled that Ecology policies and procedures
    adopted in response to cuts in the funding of a permitting program were subject to the
    rulemaking process of the Administrative Procedure Act. Ecology adopted one policy
    that granted priority in processing water applications to emergencies involving public
    health, changes of existing rights, and short-term public projects. Ecology also adopted
    policies regarding the use of the watershed assessment process for the purpose of making
    decisions on applications for water rights, and for the ranking of watersheds for
    assessment. Ecology acknowledged its decisions had “general applicability” to all
    pending water right applicants. The right to apply and be considered under the statutory
    criteria for a groundwater withdrawal permit was a “benefit or privilege” conferred by
    statute. Hillis contains many similarities to Loyal Pig’s challenge to Ecology’s action
    24
    No. 36525-5-III
    Loyal Pig, LLC v. Department of Ecology
    except that, in Hillis, Ecology did not administer the explicit provisions of a statute.
    Neither did Ecology change its interpretation of a statute.
    The Department of Ecology also asks that we reverse the superior court’s refusal to
    strike portions of the declarations of Darryll Olsen and Timothy Reierson. Because of our
    decision in favor of Ecology, we decline to address this assignment of error.
    CONCLUSION
    We hold that Loyal Pig must again calculate its annual consumptive quantity in
    order for the Department of Ecology to process its 2017 application for a change in the
    water right. We, therefore, reverse the superior court. We also revoke the injunction
    against Ecology from enforcing its interpretation of RCW 90.03.380(1). We reinstate the
    ruling of the Pollution Control Hearings Board.
