    STATE OF WASHINGTON DEPARTMENT                              PUBLISHED OPINION
    OF ECOLOGY,
    Respondent,
    CENTER FOR ENVIRONMENTAL LAW &
    POLICY,
    Intervenor.
    MELNICK, J. — The Dungeness River in the Olympic Peninsula flows 32 miles from the
    Olympic Mountains north into the Strait of Juan de Fuca. The river and its watershed are home to
    numerous species of salmon and trout, including endangered Chinook and summer chum salmon,
    steelhead, and bull trout. Water from the Dungeness watershed has been scarce for decades and
    critically low stream flows in the summer and fall have proven detrimental to recovery of
    endangered fish populations.
    In 2005, the Elwha-Dungeness Planning Unit enacted a watershed plan, seeking to address
    the situation and make water management recommendations to the Department of Ecology (DOE)
    for regulation of the Dungeness Basin.
    51221-1-II
    In November 2012, DOE promulgated an administrative rule (Dungeness Rule) that
    regulated the use and appropriation of all surface and groundwater in the watershed. The
    Dungeness Rule established minimum instream flows (MIFs) for the Dungeness River and its
    tributaries, required mitigation and metering for all new water appropriations, including permit
    exempt wells (PE wells), and closed the basin to new surface water withdrawals for part of the
    year.
    Clallam County property owners Magdalena Bassett and Denman Bassett, and the Olympic
    Resource Protection Council (ORPC),1 a non-profit corporation who seeks to balance
    environmental protection with private property rights, (collectively “plaintiffs”) challenged the
    Dungeness Rule in superior court, claiming that it failed to meet procedural and substantive
    Administrative Procedures Act (APA) requirements. The court upheld the rule and the plaintiffs
    appeal.
    DOE neither exceeded its statutory authority nor violated any required rulemaking
    procedures. In addition, the Dungeness Rule is not arbitrary and capricious. We affirm.
    FACTS
    I.        DUNGENESS RULE
    In November 2012, DOE filed the Dungeness Rule with an effective date of January 2,
    2013. WAC 173-518-010. To protect low stream flows and existing water rights, DOE found that
    water was not reliably available for new consumptive uses in the Dungeness watershed. WAC
    173-518-050. DOE wanted to satisfy present and future human needs, retain natural surface water
    bodies in the watershed, protect instream values and resources, and implement its obligations under
    the local watershed plan. WAC 173-518-020.
    1
    The Bassetts are members of the ORPC.
    2
    51221-1-II
    The Dungeness Rule established MIFs2 for the Dungeness River and its tributaries. It also
    heavily regulated access to surface water and groundwater in the basin. We begin by detailing the
    primary effects of the rule.
    A.      INSTREAM FLOWS AND RESERVES
    The Dungeness Rule established MIFs for the Dungeness River and eight smaller creeks
    in the basin. WAC 173-518-040 & Table II. These MIFs became appropriations of water under
    the prior appropriation doctrine3 so that future appropriations could not disturb them. See WAC
    173-518-040(3); RCW 90.03.345. DOE based the MIFs on recommendations of the 2005 Elwha-
    Dungeness Watershed Plan, discussed further below. WAC 173-518-040(1), (2). DOE’s objective
    in establishing MIFs was the protection and preservation of wildlife, fish, scenic, aesthetic, and
    other environmental and navigational values.
    DOE also established reserves of groundwater, not subject to the MIFs, specifically for
    domestic use.4 WAC 173-518-080. DOE found that the public interest in access to domestic water
    overrode potential impacts to instream resources. WAC 173-518-080. Domestic water users who
    2
    MIFs are appropriations of water to the stream, set by rule, to guarantee future water availability
    in the basin, continued existence of the stream, and protect and preserve instream resources and
    values. The rule uses the term “instream flow” to mean the same as “base flow,” “minimum flow,”
    and “minimum instream flow” as used in various statutes. WAC 173-518-030.
    3
    An “appropriation” is a term of art meaning “the assignment of a permanent legal water right,”
    under prior appropriation doctrine. Foster v. Dep’t of Ecology, 
    184 Wn.2d 465
    , 473-74, 
    362 P.3d 959
     (2015). Prior appropriation doctrine is the cornerstone of Washington water law.
    Fundamentally, it is the “long-standing principle that water appropriations have priority over other
    appropriations acquired later in time: ‘as between appropriations, the first in time shall be the first
    in right.’” Fox v. Skagit County, 
    193 Wn. App. 254
    , 264, 
    372 P.3d 784
     (2016) (quoting RCW
    90.03.010)). We discuss its influence on this case at length below.
    4
    “Domestic use” is use of water “associated with human health and welfare needs,” and it includes
    “drinking, bathing, sanitary purposes, cooking, laundering, and other incidental household uses.”
    WAC 173-518-030.
    3
    51221-1-II
    complied with a list of DOE conditions could use water from the reserves for their domestic needs,
    despite potential impacts to MIFs. WAC 173-518-080(2). The rule forbade any consumptive use5
    from impacting MIFs unless it came from the groundwater reserve or was subject to mitigation, as
    discussed below. WAC 173-518-040(5).
    B.      CLOSURES AND MITIGATION
    Because of water scarcity, DOE determined that surface water was not reliably available
    for new consumptive uses in the basin. The rule closed year-round eight specific tributaries as
    well as all unnamed tributaries to the Dungeness River. WAC 173-518-050. It also closed the
    Dungeness River mainstem between July 15 and November 15 every year. WAC 173-518-050.
    Surface water and groundwater sources within the Dungeness watershed are hydraulically
    connected. WAC 173-518-070(1). Accordingly, the Dungeness Rule closed the watershed to new
    groundwater appropriations, including new permit-exempt wells,6 subject to three specific
    exceptions. WAC 173-518-070. A new prospective groundwater user would be required to either
    (1) use the water for a nonconsumptive use; (2) demonstrate scientifically to DOE’s satisfaction
    that the use would not adversely affect any closed surface waters; or (3) obtain mitigation.7 WAC
    173-518-070(3).
    5
    A “consumptive use” is any use of water that “diminishes the volume or quality of the water
    source.” WAC 173-518-030.
    6
    Most appropriations of groundwater require a permit from DOE, subject to RCW 90.44.050.
    However, groundwater withdrawals of less than 5,000 gallons per day for certain uses do not
    require a permit. RCW 90.44.050. The Dungeness Rule’s effects on PE wells are discussed further
    below, as they are among the primary disputes in this case.
    7
    Mitigation is “action taken to offset impacts from future water appropriations on closed surface
    water bodies or senior water rights” including MIFs set by the rule. WAC 173-518-030.
    4
    51221-1-II
    To obtain mitigation, the rule established a Dungeness water exchange, through which new
    users could purchase credits to offset any new consumptive water use. WAC 173-518-070(3)(a)(i).
    Alternatively, new consumptive users could propose their own mitigation plan. WAC 173-518-
    070(3)(a)(ii), -075. Mitigation plan requirements included that new consumptive water uses not
    impair any existing water rights. WAC 173-518-075(2)(a).
    Finally, the rule required metering of all future new surface water and groundwater
    appropriations in the basin. WAC 173-518-060.
    II.     PASSAGE OF RULE
    A.      BACKGROUND
    The Dungeness watershed included parts of Clallam and Jefferson counties around the
    Dungeness River, near Sequim. The Dungeness mainstem averaged a flow of 701 cubic feet per
    second during June and 171 cubic feet per second in September, the months with the highest and
    lowest streamflows, between 1924 and 2011. Historically, irrigators diverted up to 80 percent of
    the Dungeness’s natural flow. In 1998, companies and irrigation districts began to voluntarily
    limit their diversions to no more than 50 percent of the river.
    In January 2012, groundwater levels were declining due to variations in rainfall, changes
    in irrigation practices, irrigation ditch piping, and increased well withdrawals associated with
    population growth. Approximately 14,000 wells and well hookups withdrew about 5.98 million
    gallons per day (gpd), 2.71 million gpd of which was consumptive. This amount did not include
    uses for irrigation, golf course, dairy, or industrial water.
    1.      Elwha-Dungeness Watershed Plan
    In 2005, the Elwha-Dungeness Planning Unit, consisting of Clallam County, the City of
    Port Angeles, the Elwha Klallam Tribe, the Jamestown S’Klallam Tribe, the Agnew Irrigation
    5
    51221-1-II
    District, and DOE adopted the Elwha-Dungeness Watershed Plan (Plan). The Plan assessed the
    status of water resources in Water Resource Inventory Area (WRIA) 18, the area ultimately
    affected by the Dungeness Rule, and addressed competing demands for water within the WRIA.
    The Plan was the result “of a lengthy, collaborative, and consensus-based process involving
    all key stakeholders in the watershed.” Administrative Record (AR) at ECY069806. It addressed
    water quantity, water quality, habitat, instream flows, stormwater, land use and management,
    education and outreach, and watershed management.
    The Plan suggested strategies for water management in the Dungeness Basin, including
    protection of instream flows and limitation of PE wells.        It recommended that continued
    groundwater withdrawals be conditioned on mitigation to surface water impacts and increased
    regulation of PE wells. It suggested the creation of a groundwater reserve to facilitate land use
    planning, manage growth, and protect instream flows.
    A “central purpose” of the Plan was “to recommend instream flows for streams and rivers
    within the WRIA, for use by [DOE] as rule-making discussions beg[a]n.” AR at ECY070473.
    The planning unit found that river flows were critical to fish at all lifestages and that optimal
    volume and timing of flows provide numerous ecological benefits to fish.              The Plan’s
    recommended instream flows intended to condition new water rights in the basin on maintenance
    of the regulatory instream flow level in the river.
    The Plan recognized the over-appropriation of water in the basin. It observed that some
    streams had water rights exceeding natural flows in low flow seasons and instructed DOE,
    “through its rule-making procedure, [to] adopt instream flow levels and then use them in its
    management of subsequent water rights applications for WRIA 18 streams.” AR at ECY070473.
    It proposed specific instream flow numbers for numerous streams in the basin, including the
    6
    51221-1-II
    Dungeness mainstem. These recommended numbers are identical to those DOE ultimately
    adopted in the Dungeness Rule.8 WAC 173-518-040, Table II.
    2.     Dungeness Rule
    In 2006, DOE began working with the local community in eastern Clallam County to draft
    the Dungeness Rule’s language. It put development of the rule on hold in late 2010 while local
    water resource managers focused on issues outside the scope of the rule. In February 2011, DOE
    agreed with Clallam County and the Sequim-Dungeness Water Users Association (WUA) that it
    would have a rule in place by August 2012.
    DOE filed a proposed version of the Dungeness Rule on May 9, 2012, held a public hearing
    on the rule on June 28, and left the public comment period open until July 9. In November 2012,
    DOE filed a concise explanatory statement, describing the rule’s effects and responding to each of
    the hundreds of public comments. DOE published the final rule on November 16. It went into
    effect on January 2, 2013.
    B.      COST-BENEFIT AND LEAST BURDENSOME ALTERNATIVE ANALYSES
    Alongside the final rule, DOE published a final cost-benefit analysis (CBA) which
    determined that, over a 20 year period, the Dungeness Rule would cost between $9.4 million and
    $26.1 million and provide between $32.1 million and $79.7 million in benefits. DOE maintained
    that the CBA was optional because the Dungeness Rule was not a significant legislative rule.
    DOE also published a least-burdensome alternatives (LBA) analysis, in which it
    determined that the Dungeness Rule as written was the least burdensome out of seven alternatives.
    8
    The Rule did not adopt MIFs for every stream for which the Plan recommended MIFs, but those
    it did adopt were all identical to the levels suggested in the Plan.
    7
    51221-1-II
    DOE did not perform a separate analysis to determine whether the rule produced the
    maximum net benefits.
    III.   LEGAL CHALLENGE
    Under the Dungeness Rule, the Bassetts could not obtain a water right for their Clallam
    County property which reduced its value.
    In January 2014, ORPC formally requested that DOE amend the Dungeness Rule, claiming
    that the rule was inconsistent with state law and established precedent. Specifically, it attacked
    DOE’s use of the overriding considerations of public interest (OCPI) exception to create reserves
    of water and DOE’s establishment of MIFs in the Dungeness watershed without applying either a
    maximum net benefits test or the four-part test for new water appropriations. DOE denied the
    petition on March 18.
    In December 2014, the Bassetts and ORPC filed a petition for a declaratory judgment that
    the Dungeness Rule was invalid.       The Center for Environmental Law and Policy (CELP)
    intervened as a defendant. In December 2016, the superior court concluded that the plaintiffs had
    not met their burden to show the Dungeness Rule was invalid and dismissed the petition with
    prejudice.
    Plaintiffs petitioned for direct review at the Supreme Court. After briefing was complete,
    the Supreme Court transferred the case to this court.
    ANALYSIS
    I.     LEGAL PRINCIPLES
    A.      ADMINISTRATIVE RULE CHALLENGE
    The party challenging a rule has the burden of establishing that it is invalid. Swinomish
    Indian Tribal Cmty. v. Dep’t of Ecology, 
    178 Wn.2d 571
    , 580, 
    311 P.3d 6
     (2013). Under the APA,
    8
    51221-1-II
    we must declare an administrative rule invalid if “[t]he rule violates constitutional provisions; the
    rule exceeds the statutory authority of the agency; the rule was adopted without compliance with
    statutory rule-making procedures; or the rule is arbitrary and capricious.” RCW 34.05.570(2)(c).
    In reviewing administrative action, “we sit in the same position as the trial court and apply the
    [APA] standards directly to the agency’s administrative record.” Granton v. Wash. State Lottery
    Comm’n, 
    143 Wn. App. 225
    , 231, 
    177 P.3d 745
     (2008) (footnote omitted).
    Rules that are “‘reasonably consistent with the controlling statute[s]’” do not exceed
    statutory authority, but rules inconsistent with their implementing statutes are invalid. Swinomish,
    178 Wn.2d at 580-81 (quoting Wash. Pub. Ports. Ass’n v. Dep’t of Revenue, 
    148 Wn.2d 637
    , 646,
    
    62 P.3d 462
     (2003)). An agency’s action is arbitrary and capricious if it “is the result of willful
    and unreasoning disregard of the facts and circumstances.” Providence Hosp. of Everett v. Dep't
    of Soc. & Health Servs., 
    112 Wn.2d 353
    , 356, 
    770 P.2d 1040
     (1989). The majority of plaintiffs’
    challenges are allegations that DOE exceeded statutory authority or violated statutory rulemaking
    procedures.
    B.      STATUTORY INTERPRETATION
    We review questions of statutory interpretation de novo. Jametsky v. Olsen, 
    179 Wn.2d 756
    , 761, 
    317 P.3d 1003
     (2014). In interpreting statutes, “we give effect to the plain meaning of
    the language used as the embodiment of legislative intent.” Swinomish, 178 Wn.2d at 581. We
    give effect to the plain meaning of the statute as “derived from the context of the entire act as well
    as any ‘related statutes which disclose legislative intent about the provision in question.’”
    Jametsky, 
    179 Wn.2d at 762
     (quoting Dep’t of Ecology v. Campbell & Gwinn, LLC, 
    146 Wn.2d 1
    ,
    11, 
    43 P.3d 4
     (2002)).
    9
    51221-1-II
    If a statute’s meaning is plain on its face, we give effect to that meaning as an expression
    of legislative intent. Blomstrom v. Tripp, 
    189 Wn.2d 379
    , 390, 
    402 P.3d 831
     (2017). However,
    if, “after this inquiry, the statute remains ambiguous or unclear, it is appropriate to resort to canons
    of construction and legislative history.” Blomstrom, 189 Wn.2d at 390. Although we generally
    accord substantial deference to agency decisions, “we do not defer to an agency the power to
    determine the scope of its own authority.” In re Elec. Lightwave, Inc., 
    123 Wn.2d 530
    , 540, 
    869 P.2d 1045
     (1994).
    C.      WASHINGTON WATER LAW
    Evaluation of statutory provisions concerning water rights “almost always requires
    consideration of numerous related statutes in the water code.” Swinomish, 178 Wn.2d at 582. In
    this case, we are asked to interpret provisions of the water code, the Water Resources Act of 1971
    (WRA), the Minimum Water Flows and Levels Act (MWFLA), the Watershed Planning Act
    (WPA), and the Regulation of Public Groundwaters. We begin by reviewing the fundamentals of
    Washington water law.
    1.      Prior Appropriation Doctrine
    Washington follows the prior appropriation doctrine of water rights, summarized: “‘as
    between appropriations, the first in time shall be the first in right.’” Fox v. Skagit County, 
    193 Wn. App. 254
    , 264, 
    372 P.3d 784
     (2016) (quoting RCW 90.03.010).
    The prior appropriation doctrine “‘provides that a right to water can be established only by
    putting water to beneficial use and that the first such use in time is the first such use in right.’”
    Hallauer v. Spectrum Props., Inc., 
    143 Wn.2d 126
    , 134, 
    18 P.3d 540
     (2001) (quoting Charles B.
    Roe & Peter R. Anderson, Water Law, in 1C KELLY KUNSCH, WASHINGTON PRACTICE: METHODS
    OF PRACTICE   § 91.4 (4th ed. 1997)). Once a water right is established by putting the water to a
    10
    51221-1-II
    beneficial use, that right is senior to, and therefore superior to, any water rights established
    afterward. Fox, 193 Wn. App. at 268-69.
    The water code establishes a permitting procedure by which individuals seeking to
    withdraw water for a beneficial use may apply to DOE for a permit to do so. RCW 90.03.260-
    .340. Ctr. for Envtl. Law & Policy v. Dep’t of Ecology, 
    196 Wn. App. 360
    , 369, 
    383 P.3d 608
    (2016) (CELP), summarized the process.
    Once a party has applied for a water right, [DOE] determines what water, if any, is
    available and finds and determines to what beneficial use or uses it can be applied.
    If [DOE] is satisfied that water is available and the proposed use is a beneficial use,
    it issues a permit specifying the amounts of water that can be taken and the
    beneficial uses to which that water may be applied. RCW 90.03.290 establishes a
    four part test that [DOE] applies when considering an application for a water right
    permit. Under the statute, [DOE] must affirmatively find (1) that water is available
    (2) for a beneficial use and that (3) an appropriation will not impair existing rights
    or (4) be detrimental to the public welfare.
    CELP, 196 Wn. App. at 369 (internal citations omitted).
    2.      Water Management
    The WRA declares fundamentals of Washington water management. RCW 90.54.020. It
    states that the utilization and management of Washington waters shall be guided by a number of
    principles and contains a list of beneficial uses of water, including, as relevant here, domestic use,
    stock watering, commercial, agricultural, irrigation, fish and wildlife maintenance and
    enhancement, and preservation of environmental and aesthetic values. RCW 90.54.020(1). The
    WRA does not specifically prioritize between these many competing beneficial water uses.
    However, it provides that “[a]llocation of waters among potential uses and users shall be based
    generally on the securing of the maximum net benefits for the people of the state.” RCW
    90.54.020(2). Maximum net benefits constitute “total benefits less costs including opportunities
    lost.” RCW 90.54.020(2).
    11
    51221-1-II
    Additional water management fundamentals include that “[t]he quality of the natural
    environment shall be protected and, where possible, enhanced” by retaining base flows of rivers
    and streams “necessary to provide for preservation of wildlife, fish, scenic, aesthetic and other
    environmental values, and navigational values,” but also that “[a]dequate and safe supplies of
    water shall be preserved and protected in potable condition to satisfy human domestic needs.”
    RCW 90.54.020(3), (5).
    In 1997, the legislature enacted the WPA in order to “develop a more thorough and
    cooperative method of determining what the current water resource situation is in each water
    resource inventory area of the state and to provide local citizens with the maximum possible input
    concerning their goals and objectives for water resource management and development.” RCW
    90.82.005. The WPA provided procedures for local governments and tribes to cooperate with
    DOE to establish water management plans for their local watersheds. RCW 90.82.040, .060,
    .080(1)(b).
    II.    MINIMUM INSTREAM FLOWS
    Much of the dispute over the Dungeness Rule concerns MIFs and the process required to
    set them. The Rule established MIFs at levels recommended by the 2005 Elwha-Dungeness Plan
    for the Dungeness mainstem and eight smaller creeks in the Dungeness basin.
    The plaintiffs contend that, before DOE could set these MIFs, DOE was required to
    perform a maximum net benefits analysis and determine whether the MIFs met the four-part test
    for new appropriations of water. See RCW 90.54.020(2); RCW 90.03.290(3). We disagree.
    12
    51221-1-II
    A.      LEGAL PRINCIPLES
    MIFs are appropriations of water for purposes of the water code. RCW 90.03.345. New
    water use permits must be conditioned to either protect MIFs or require mitigation of impacts to
    them. RCW 90.03.247(1).
    DOE has statutory authority to establish MIFs. The Minimum Water Flows and Levels
    Act (MWFLA) authorizes DOE to “establish minimum water flows or levels” to protect fish or
    wildlife, or “whenever it appears to be in the public interest.” RCW 90.22.010. MIFs adopted
    under this statute “shall be provided for through the adoption of rules.” RCW 90.22.020. Before
    establishing a rule setting MIFs, DOE must provide notice to the community and hold a public
    hearing. RCW 90.22.020.
    The WPA also includes a process for establishing MIFs through a “collaborative effort”
    between DOE and the watershed planning unit. RCW 90.82.080(1)(a)(ii). Once the planning unit
    has decided to include MIFs, DOE must “undertake rule making to adopt flows,” either through
    the regular or expedited process for adopting rules under the APA, or through a process “that uses
    public hearings and notice provided by the county legislative authority to the greatest extent
    possible.” RCW 90.82.080(1)(b).
    These various water law statutes “plainly provide that minimum flows, once established by
    rule, are appropriations which cannot be impaired by subsequent withdrawals.” Postema v.

    B.      MAXIMUM NET BENEFITS
    Plaintiffs contend that DOE exceeded its statutory authority by adopting the Dungeness
    Rule without performing a maximum net benefits analysis. They argue that any time DOE
    allocates water for any purpose, including MIFs, it must perform a maximum net benefits analysis.
    We disagree.
    The WRA lists guiding principles for water management in Washington. RCW 90.54.020.
    It begins: “Utilization and management of the waters of the state shall be guided by the following
    general declaration of fundamentals.” RCW 90.54.020. One of these guiding fundamentals states
    that “[a]llocation of waters among potential uses and users shall be based generally on the securing
    of the maximum net benefits for the people of the state. Maximum net benefits shall constitute
    total benefits less costs including opportunities lost.” RCW 90.54.020(2).
    Other subsections of the same statute demand that “[t]he quality of the natural environment
    shall be protected and, where possible, enhanced,” “[p]erennial rivers and streams of the state shall
    be retained with base flows necessary to provide for preservation of wildlife, fish, scenic, aesthetic
    and other environmental values, and navigational values,” and “[l]akes and ponds shall be retained
    substantially in their natural condition.” RCW 90.54.020(3). Additionally, “[a]dequate and safe
    supplies of water shall be preserved and protected in potable condition to satisfy human domestic
    needs” and “[w]aters of the state shall be of high quality.” RCW 90.54.020(3)(b), (5).
    The legislature amended the water code in 1979, adding “maximum net benefits” language
    to the general statement of Washington water policy. RCW 90.03.005; LAWS OF 1979 ex. s. ch.
    216, § 8. The amended policy statement declared that:
    It is the policy of the state to promote the use of the public waters in a fashion which
    provides for obtaining maximum net benefits arising from both diversionary uses
    of the state’s public waters and the retention of waters within streams and lakes in
    sufficient quantity and quality to protect instream and natural values and rights.
    14
    51221-1-II
    RCW 90.03.005.
    In interpreting the maximum net benefits language of the WRA,9 we derive its meaning
    “from the context of the entire act as well as any ‘related statutes which disclose legislative intent
    about the provision in question.’” Jametsky, 
    179 Wn.2d at 762
     (quoting Campbell & Gwinn, 146
    Wn.2d at 11). We avoid reading statutes so as to produce absurd results. Tingey v. Haisch, 
    159 Wn.2d 652
    , 664, 
    152 P.3d 1020
     (2007).
    “[S]tatutory policy statements as a general rule do not give rise to enforceable rights and
    duties.” Aripa v. Dep’t of Soc. & Health Servs., 
    91 Wn.2d 135
    , 139, 
    588 P.2d 185
     (1978) overruled
    on other grounds by State v. WWJ Corp., 
    138 Wn.2d 595
    , 
    980 P.2d 1257
     (1999). In Aripa, the
    Supreme Court construed the following legislative mandate:
    “The director of institutions shall provide for the establishment of programs and
    procedures for convicted persons at the state penitentiary, which are designed to be
    corrective, rehabilitative and reformative of the undesirable behavior problems of
    such persons, as distinguished from programs and procedures essentially penal in
    nature.”
    Aripa, 
    91 Wn.2d at 137
     (quoting RCW 72.08.101 (repealed by LAWS OF 1988 ch. 143, § 17)). The
    plaintiff contended that this statute and another, instructing the Department of Health and Social
    Services to “‘[c]ooperate with public and private agencies in establishing and conducting programs
    to provide treatment for alcoholics,’” imposed a statutory right to alcoholism treatment while
    incarcerated. Aripa, 
    91 Wn.2d at 137
     (quoting former RCW 70.96A.050(3) (recodified as RCW
    71.24.535 by LAWS OF 2016 sp. sess. ch. 29, § 701)). The court concluded that the statutory scheme
    9
    Although Plaintiffs also cite the maximum net benefits language in the policy statement of the
    water code, their argument that DOE was required to do a formal maximum net benefits test
    focuses on the WRA language. Accordingly, we analyze the WRA language and look to the water
    code policy statement only as context.
    15
    51221-1-II
    was “understandably nonspecific on the precise nature and extent of corrective programs” and did
    “not give rise to enforceable rights and duties.” Aripa, 
    91 Wn.2d at 138-39
    .
    Swinomish interpreted the “maximum net benefits” language of the cater code in the
    context of DOE’s attempt to create water reservations for out-of-stream uses. 178 Wn.2d at 595-
    96. The court observed that “[o]btaining maximum benefits, prudent management of the state’s
    water resources with input of interested entities, preservation of water within streams and lakes as
    necessary for instream and natural values, and avoidance of wasteful practices are important goals
    of present water resource management.” Swinomish, 178 Wn.2d at 596. Swinomish also noted
    that maximum net benefits refers to both diversionary uses, which can be quantified in dollars, but
    also high water quality and aesthetic values, which cannot be economically quantified. 178 Wn.2d
    at 600.
    Plaintiffs contend that use of the word “shall” indicates that the legislature intended to
    impose a mandatory duty upon DOE to secure the maximum net benefits. The word “shall”
    appears 22 times in RCW 90.54.020. Some examples include the WRA’s declarations that “[t]he
    quality of the natural environment shall be preserved”; “[p]erennial rivers and streams of the state
    shall be retained with base flows”; “[l]akes and ponds shall be retained substantially in their natural
    condition”; “[w]aters of the state shall be of high quality”; DOE, other state agencies, and local
    governments “shall evaluate the potential for the development of new storage projects and the
    benefits and effects of storage in reducing damage to stream banks and property”; “[a]dequate and
    safe supplies of water shall be preserved and protected in potable condition to satisfy human
    domestic needs.” RCW 90.54.020(3), (4), (5) (emphasis added). If the legislature’s use of the
    word “shall” imposed a formal test on DOE before it allocated any amount of water, DOE would
    16
    51221-1-II
    be overwhelmed with countless conflicting tests and unable to perform its water management
    duties. We reject this argument because it would lead to an absurd result.
    When the legislature intends to impose a specific balancing test on DOE, it has shown that
    it knows how to do so. For example, the water code establishes a four-part test DOE must apply
    when considering new water permits. That statute states:
    [DOE] shall make and file as part of the record in the matter, written findings of
    fact concerning all things investigated, and if it shall find that there is water
    available for appropriation for a beneficial use, and the appropriation thereof as
    proposed in the application will not impair existing rights or be detrimental to the
    public welfare, it shall issue a 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.
    RCW 90.03.290(3).
    If the legislature meant to require DOE to make specific maximum net benefits findings
    for every allocation of water, it could have used similar language to that in the water code,
    requiring DOE to “make and file as part of the record” a written maximum net benefits finding. It
    did not do so because the maximum net benefits language of the WRA instructs DOE how to
    generally exercise its discretion and expertise in water management. It does not impose a formal
    test.
    C.     FOUR-PART APPROPRIATIONS TEST
    Plaintiffs contend that DOE exceeded its statutory authority by appropriating water for
    instream flows without applying the water code’s four-part test for new appropriations. They
    contend that instream flows are water appropriations with priority dates that must go through the
    same process as any other water appropriation. We disagree.
    When evaluating applications for water appropriations, the water code instructs DOE to
    verify that the permit satisfies four criteria: “(1) water is available for appropriation (2) for a
    17
    51221-1-II
    beneficial use and (3) an appropriation will not impair existing rights or (4) be detrimental to the
    public welfare.” Foster, 184 Wn.2d at 472; see RCW 90.03.290(3).
    Earlier subsections of this statute clarify that it specifically concerns applications to
    appropriate water. When an application complying with the water code and applicable rules has
    been filed, subsection (1) directs DOE to “investigate the application, and determine what water,
    if any, is available for appropriation, and find and determine to what beneficial use or uses it can
    be applied.”    RCW 90.03.290(1).       Another subsection details the process for issuance of
    preliminary permits when a water right application fails to furnish sufficient information for DOE
    to issue a permanent appropriation permit. RCW 90.03.290(2).
    As discussed above, DOE’s authority to establish MIFs comes from multiple sources, all
    of which use a different process than the water code’s applications to appropriate water. The
    MWFLA gives DOE authority to establish MIFs “for the purposes of protecting fish, game, birds
    or other wildlife resources, or recreational or aesthetic values . . . whenever it appears to be in the
    public interest.” RCW 90.22.010. It also specifies that MIFs should be established “through the
    adoption of rules” and provides several procedural requirements, including a public hearing with
    notice to the affected community. RCW 90.22.020
    In this case, DOE’s MIF authority derives from the WPA, which allows it to set MIFs
    based on the recommendation of a Watershed Plan through an expedited process sidestepping
    many APA procedural requirements. See RCW 90.82.080(1)(b). This provision includes many
    procedural safeguards, including that DOE may only promulgate rules under this statute if the local
    governments in the area agree to set MIFs and create a formal watershed plan. RCW 90.82.080.
    Regardless which MIF authority DOE invoked in this case, application of the four-part test
    for new water appropriations is inconsistent with the purpose of MIFs. The first part of the test
    18
    51221-1-II
    inquires whether water is “available for appropriation.” RCW 90.03.290(3). The very purpose of
    establishing MIFs is to ensure that water remains available in the basin. If water must be available
    for DOE to establish MIFs, DOE would be unable to use them when they are most vital to protect
    instream values and resources.
    Plaintiffs emphasize that MIFs are “appropriations” within the meaning of the water code
    and thus must be subject to the four-part test. Plaintiffs are correct that, “[o]nce established, a
    minimum flow constitutes an appropriation with a priority date as of the effective date of the rule
    establishing the minimum flow.” Postema, 142 Wn.2d at 81 (emphasis added). However, the
    process for establishing MIFs is very different than that for granting an appropriation permit under
    RCW 90.03.290’s appropriation procedures.
    Plaintiffs also compare MIFs to reservations, which must “meet the same requirements as
    any appropriation of water under the water code.” Br. of Appellant at 27 (quoting Swinomish, 178
    Wn.2d at 588) (emphasis omitted). Although the same water code section clarifies that both
    reservations and MIFs are appropriations, that does not suggest that they are created the same way.
    See RCW 90.03.345; RCW 90.54.050; RCW 90.82.080. Unlike MIFs, reservations involve
    withdrawal of water for out-of-stream use. Determining whether water is “available” for such out-
    of-stream uses makes sense, as it would with a permit application. This reasoning does not apply
    to MIFs, where requiring water availability would defeat their very purpose.
    We conclude that DOE may exercise its authority to set MIFs without resorting to the four-
    part test for evaluation of water appropriation permits.
    III.   RESERVES AND OCPI EXCEPTION
    The Dungeness Rule established reserves of water, not subject to MIFs, specifically for
    domestic use. DOE found that these reserves served overriding considerations of public interest.
    19
    51221-1-II
    WAC 173-518-080(1); see RCW 90.54.020(3)(a). If domestic water users complied with a list of
    specific conditions, they could use reserve water despite potential impacts to the MIFs. WAC 173-
    518-080.
    Plaintiffs claim that DOE exceeded its statutory authority by establishing these reserves.
    They contend that the legislature’s express approval of the Dungeness Rule’s water reserves does
    not cure this defect because it does not address conflicting case law from Swinomish and Foster
    relating to the overriding considerations of public interest exception. In the alternative, they
    contend that reading the express legislative approval of the Dungeness Rule as determinative of
    this case would violate separation of powers. We reject these contentions.
    The WRA provides DOE the authority to “[r]eserve and set aside waters for beneficial
    utilization in the future.” RCW 90.54.050(1). These reservations constitute appropriations within
    the meaning of the water code with priority dates as of the effective dates of their establishment.
    RCW 90.03.345. DOE creates these reservations by administrative rule. RCW 90.54.050.
    Once MIFs are established for a body of water, they are appropriations “which may not be
    impaired” by subsequent withdrawals. Postema, 142 Wn.2d at 81. The “narrow exception to this
    rule is found in RCW 90.54.020(3)(a), which provides that withdrawals of water which would
    conflict with the base flows ‘shall be authorized only in those situations where it is clear that
    overriding considerations of the public interest will be served.’” Postema, 142 Wn.2d at 81
    (quoting RCW 90.54.020(3)(a)).      This provision of RCW 90.54.020(3)(a) is known as the
    overriding considerations of public interest (OCPI) exception.
    In Swinomish, DOE relied on the OCPI exception to create water reservations that would
    have allowed out-of-stream uses conflicting with preexisting MIFs. 178 Wn.2d at 576. DOE
    found that “important public interests would be significantly advanced by the reservations because
    20
    51221-1-II
    without them, new withdrawals for domestic, municipal, industrial, agricultural, and stock
    watering uses would be interrupted when stream flows fall” to the MIF levels. Swinomish, 178
    Wn.2d at 579. DOE used a balancing test to determine whether beneficial uses of water would
    outweigh the harm resulting from impairing instream flows. Swinomish, 178 Wn.2d at 586.
    The Supreme Court invalidated the reservations, concluding that DOE’s interpretation of
    the OCPI exception “would relegate minimum flow water rights to a lesser class of water right
    than others, with the water subject to reallocation if [DOE] decides that reservations for other
    beneficial uses would make better use of the state’s water.” Swinomish, 178 Wn.2d at 596. The
    court concluded that the OCPI exception “cannot reasonably be read to replace the many statutes
    that pertain to appropriation of the state’s water and minimum flows.” Swinomish, 178 Wn.2d at
    598. It noted that allowing DOE to use the OCPI exception to provide water for domestic wells
    or other specific uses would allow DOE to avoid the normal statutory procedures and the prior
    appropriation doctrine. Swinomish, 178 Wn.2d at 598.
    In Foster, the City of Yelm sought an appropriation permit that would impair MIFs. 184
    Wn.2d at 469. DOE issued the permit pursuant to the OCPI exception, conditioned on Yelm’s
    application for an extensive mitigation plan which would offset the impacts of the new
    appropriation. Foster, 184 Wn.2d at 469.
    The Supreme Court distinguished “withdrawals of water,” as used in the OCPI exception,
    from “appropriations” of water, as used elsewhere throughout various water law statutes. Foster,
    184 Wn.2d at 473-74. It held that “the OCPI exception does not allow for the permanent
    impairment of minimum flows” because it allows for “withdrawals,” or the “physical act of
    removing water,” as opposed to “appropriations,” which would be permanent water rights. Foster,
    184 Wn.2d at 474-75 (emphasis added). Foster held that the OCPI exception allows “only
    21
    51221-1-II
    temporary impairment of minimum flows” and that “[m]unicipal water needs do not rise to the
    level of ‘extraordinary circumstances’” required to apply the OCPI exception. 184 Wn.2d at 477.
    In this case, DOE “weighed the public interest supported by providing a limited amount of
    water for domestic water supply against the potential for negative impact to instream resources.”
    WAC 173-518-080. It found that the public interest advanced by the reserves “clearly overrides
    the potential for negative impacts on instream resources.” WAC 173-518-080. In making this
    decision, DOE cited the OCPI exception.10 DOE distinguishes Swinomish and Foster on the basis
    that the rules invalidated in those cases used the OCPI exception to appropriate water after MIFs
    were already established. It claims the rule in this case avoids those problems by adopting MIFs
    and reserves of water simultaneously, such that neither is superior to the other for purposes of prior
    appropriation doctrine.
    DOE’s argument fails to account for the express holding of Foster that “the OCPI
    exception does not allow for the permanent impairment of minimum flows.” 184 Wn.2d at 475.
    This holding is not dependent on prior appropriation doctrine, but the OCPI exception’s use of the
    word “withdrawal” rather than “appropriation.” Foster, 184 Wn.2d at 474. DOE may not use the
    OCPI exception to permanently impair MIFs, regardless of when it does so. Our analysis does not
    end here, however, because the legislature has expressly approved of the Dungeness Rule’s water
    reserves.
    10
    The Dungeness Rule invokes the OCPI exception and both parties assume that DOE relied on
    the OCPI exception for its establishment of reserves. See WAC 173-518-080(1). We assume that
    DOE relied on the OCPI exception to adopt these reserves, and do not address whether DOE had
    the authority to establish these reserves through other statutory authority.
    22
    51221-1-II
    After both Foster and Swinomish had been decided, the legislature announced its express
    approval of the Dungeness Rule’s water reservations. It declared:
    [DOE] shall act on all water rights applications that rely on the reservations of water
    established in WAC 173-518-080 or 173-545-090, as those provisions existed on
    March 31, 2016. The legislature declares that the reservations of water established
    in WAC 173-518-080 and 173-545-090, as those provisions existed on March 31,
    2016, are consistent with legislative intent and are specifically authorized to be
    maintained and implemented by [DOE].
    RCW 90.54.210(1). The same statute also cautioned that “[t]his section does not affect [DOE’s]
    authority to lawfully adopt, amend, or repeal any rule, including WAC 173-518-080 or 173-545-
    090. RCW 90.54.210(2). WAC 173-518-080 is the section of the Dungeness Rule that established
    water reserves pursuant to the OCPI exception.
    We read statutes together to “determine the legislative intent underlying the entire statutory
    scheme.” In re Estate of Kerr, 
    134 Wn.2d 328
    , 343, 
    949 P.2d 810
     (1998). “A more specific statute
    supersedes a general statute only if the two statutes pertain to the same subject matter and conflict
    to the extent they cannot be harmonized.” Kerr, 
    134 Wn.2d at 343
    . In this case, as applied to the
    Dungeness Rule, RCW 90.54.210 conflicts with the OCPI exception as the Supreme Court
    interpreted it in Foster.
    Both Swinomish and Foster observed that the goal of statutory interpretation is to effectuate
    legislative intent. 178 Wn.2d at 581; 184 Wn.2d at 471. The express statement of legislative intent
    controls in this case. While DOE may not be able to generally use the OCPI exception to establish
    reserves that permanently impair instream flows, the legislature superseded the holding of Foster
    as to the specific rules it mentions in RCW 90.54.210. Accordingly, use of the OCPI exception to
    establish water reserves that may impair MIFs was within DOE’s statutory authority in this case.
    Plaintiffs contend that RCW 90.54.210 violates the separation of powers by directing the
    outcome of this case, which was pending at the time the statute was adopted.
    23
    51221-1-II
    “Occasionally, try as the court may, the legislature is disappointed with the court’s
    interpretation.” Hale v. Wellpinit Sch. Dist. No. 49, 
    165 Wn.2d 494
    , 509, 
    198 P.3d 1021
     (2009).
    In Hale, the trial court applied the statutory meaning of “disability” in the Washington Law Against
    Discrimination as the Supreme Court had interpreted it in McClarty v. Totem Elec., 
    157 Wn.2d 214
    , 
    137 P.3d 844
     (2006). 
    165 Wn.2d at 499
    . The legislature then enacted a new definition of
    “disability” with express retroactive effect. 
    165 Wn.2d at 500
    . At the time the bill passed, the
    plaintiff’s claim had already been dismissed, based on the McClarty interpretation. Hale, 
    165 Wn.2d at 499-500
    . The plaintiff filed a motion for reconsideration based on the new statutory
    definition, and the trial court denied it, concluding that the new definition violated the separation
    of powers doctrine “by attempting to reverse th[e] court’s interpretation.” Hale, 
    165 Wn.2d at 500
    .
    The Supreme Court reversed, concluding that the legislature had “acted wholly within its
    sphere of authority to make policy, to pass laws, and to amend laws already in effect.” Hale, 
    165 Wn.2d at 509
    . The legislature “exercised its authority to amend the act and change the definition
    of ‘disability’ retroactively” while being “careful not to reverse” McClarty and without interfering
    in any judicial function. Hale, 
    165 Wn.2d at 510
    .
    In this case, like Hale, the legislature enacted a new statute in response to the opinions in
    Swinomish and Foster. The legislature did not redefine the word “withdrawal” or expressly reverse
    either of those decisions. Rather, it expressed that the reserves in two specific rules were consistent
    with legislative intent and directed they be maintained. This was wholly within the legislature’s
    sphere of authority and does not violate the separation of powers.
    We conclude that the Dungeness Rule’s water reserves are consistent with express
    legislative intent and DOE did not exceed its authority by adopting them.
    24
    51221-1-II
    IV.    SURFACE WATER CLOSURE
    Because of water scarcity, the Rule closed the Dungeness basin to new appropriations from
    all tributaries year-round, and from the Dungeness mainstem for four months out of the year. WAC
    173-518-050. Plaintiffs contend that these closures exceeded DOE’s statutory authority. They
    contend that DOE may only close a basin when it lacks information and data. Accordingly, they
    argue that DOE’s closure of the basin based on its affirmative findings that water is unavailable
    exceeded its statutory authority. We disagree.
    DOE has authority to close streams to further appropriation. Postema, 142 Wn.2d at 95
    (citing RCW 43.21A.064(9); RCW 43.27A.090(7), (11); RCW 90.54.040; RCW 90.03.247); see
    also Whatcom County v. W. Wash. Growth Mgmt. Hr’gs Bd., 
    186 Wn.2d 648
    , 677, 687 n.13, 
    381 P.3d 1
     (2016) (assuming DOE has authority to “close a basin to all future appropriations”). In
    Postema, DOE adopted rules closing certain streams following a determination that water was
    unavailable from the surface water source. 142 Wn.2d at 95. The court upheld these rules, noting
    that “[s]tream closures by rule embody [DOE’s] determination that water is not available for
    further appropriations.” Postema, 142 Wn.2d at 95. “[I]f and when [DOE] makes a determination
    to close a basin to all future appropriations, including permit-exempt appropriations, this positive
    action by [DOE] amounts to a recognition that water is not available for any use.” Whatcom
    County, 186 Wn.2d at 687 n.13.
    Plaintiffs attempt to distinguish Postema on grounds that it considered the application of a
    rule to specific permit applications, not the validity of the rule itself. They further claim that
    Postema “includes no analysis of the specific rulemaking requirements for closing streams by rule,
    or the statutory authority for adopting individual stream closures by rule.” Br. of Appellant at 34-

    51221-1-II
    Postema cites four statutory sections for DOE’s authority to close basins. 142 Wn.2d at
    95.   These sections give DOE authority to “establish and promulgate rules governing the
    administration” of the water code, RCW 43.21A.064(9), to “develop and implement . . . a
    comprehensive state water resources program which will provide a process for making decisions
    on future water resource allocation and use,” RCW 90.54.040(1), and to set MIFs.              RCW
    90.03.247; see also RCW 43.27A.090(7), (11).
    In the Dungeness Rule, DOE determined that, “based on recommendations in the
    watershed plan, historical and current low stream flows, and the need to protect existing water
    rights, water is not reliably available for new consumptive uses from the streams and tributaries in
    the Dungeness River watershed.” WAC 173-518-050. Accordingly, it closed eight specific named
    tributaries and all unnamed tributaries to the Dungeness River to new appropriations year-round.
    WAC 173-518-050; Table III. It also closed the Dungeness River itself to new appropriations
    from July 15 through November 15 each year. WAC 173-518-050; Table III. The only exceptions
    to these closures concerned use of the groundwater reserve or compliance with the groundwater
    appropriation section of the rule. WAC 173-518-050 (citing WAC 173-518-070, 080, 085).
    These closures are consistent with the broad rulemaking authority delegated to DOE in
    both RCW 43.21A.064(9) and RCW 90.54.040(1). Though plaintiffs’ claim Postema offers no
    guidelines for DOE to promulgate rules closing a river basin, they do not suggest any reason that
    standard APA rulemaking procedures would not be applicable.11               See ch. 34.05 RCW.
    11
    Plaintiffs emphasize that DOE may only close basins under RCW 90.54.050 “[w]hen sufficient
    information and data are lacking to allow for the making of sound decisions” and therefore contend
    that DOE may only ever close basins under such conditions. Br. of Appellant at 35-36 (emphasis
    omitted). This argument ignores Postema and many other sources of statutory rulemaking
    authority discussed in the main text.
    26
    51221-1-II
    Pursuant to Postema and DOE’s broad authority to implement water management rules
    under numerous interrelated statutes, DOE did not exceed its authority by closing the Dungeness
    Basin to surface water withdrawals.
    V.       PERMIT-EXEMPT WELLS
    The parties dispute several aspects of the Dungeness Rule’s impacts to PE wells. Plaintiffs
    claim that the priority date for PE wells relates back to initiation of any project dependent on the
    well for water and that DOE failed to consider the cost of the lost “rights” to drill PE wells in its
    CBA and LBA analysis.
    DOE responds that rights to PE well water are not established until the person claiming the
    right has put the water to a beneficial use. It additionally contends that the CBA and LBA analysis
    were optional because the Dungeness Rule was not a significant legislative rule. We agree with
    DOE.
    A.     LEGAL PRINCIPLES
    In 1945, the legislature recognized the relationship between surface water and
    groundwater. RCW 90.44.030. It began requiring permits for appropriation of groundwater.
    RCW 90.44.050. Before issuing a groundwater permit, DOE must investigate and apply the four-
    part test from RCW 90.03.290. Campbell & Gwinn, 146 Wn.2d at 8. “[W]hen [DOE] determines
    whether to issue a permit for appropriation of public groundwater, [it] must consider the
    interrelationship of the groundwater with surface waters, and must determine whether surface
    water rights would be impaired or affected by groundwater withdrawals.” Postema, 142 Wn.2d at
    80-81.
    The groundwater statute forbids any withdrawal of groundwater without a permit. RCW
    90.44.050. However, it exempts withdrawals for stock-watering, watering small lawns or gardens,
    27
    51221-1-II
    single or group domestic uses, or industrial purposes that do not exceed 5,000 gallons per day.
    RCW 90.44.050. Withdrawals of groundwater that meet these requirements are referred to as
    “permit-exempt wells.” These wells are exempt from permitting requirements and, “to the extent
    that [the water] is regularly used beneficially,” the user is “entitled to a right equal to that
    established by a permit.” RCW 90.44.050.
    PE wells are subject to the prior appropriation doctrine, like any other water right. Fox,
    193 Wn. App. at 262. “[A]n appropriator’s right to use water from a permit-exempt withdrawal is
    subject to senior water rights, including the minimum flows established by [DOE].” Whatcom
    County, 186 Wn.2d at 669.
    B.      PRIORITY DATE
    Plaintiffs contend that the priority date for water rights relates back to the date the process
    for putting water to a beneficial use began. They claim that DOE exceeded its statutory authority
    by evaluating the priority date for PE wells as the date the water is actually put to beneficial use.
    We disagree.
    The prior appropriation doctrine “does not permit any impairment, even a de minimis
    impairment, of a senior water right.” Foster, 184 Wn.2d at 471. The Dungeness Rule states that
    it applies to the “use and appropriation of surface and groundwater in the Dungeness River
    watershed begun after” its effective date, but does not affect “[e]xisting groundwater rights
    established under the groundwater permit-exemption where regular beneficial use began before”
    the rule’s effective date. WAC 173-518-010(3).
    The Dungeness Rule may not impair water rights already existing at the time it went into
    effect. See Foster, 184 Wn.2d at 473 (observing DOE’s “end run” around the normal process,
    conflicting with prior appropriation doctrine). We must determine whether the Dungeness Rule
    28
    51221-1-II
    may apply to prospective PE well users who had already drilled or planned to drill a well, but who
    had not yet put water from the well to “regular beneficial use.”
    The water code specifically provides that water right priority dates “relate back to the date
    of filing of the original application with [DOE].” RCW 90.03.340.           Because PE wells have no
    “original application” date, prospective users of PE well water must “show ‘an intention to
    appropriate [water] followed by a reasonable diligence in applying the water to a beneficial use.’”
    Fox, 193 Wn. App. at 276-77 (quoting In re Rights to Waters of Alpowa Creek, 
    129 Wash. 9
    , 13,
    
    224 P. 29
     (1924)). If they can meet this two part test, “the date of priority of the right will ‘relate[]
    back’ to the time work was first performed to appropriate the water.”12 Fox, 193 Wn. App. at 277
    (quoting Hunter Land Co. v. Laugenour, 
    140 Wash. 558
    , 565, 
    250 P. 41
     (1926)).
    MIFs provide an exception to the statutory relation-back doctrine. Postema, 142 Wn.2d at
    80 n.2. Although “[n]ormally, the priority date for a water right . . . relates back to the date of
    application for the permit . . . where minimum flow or levels have been adopted and are in effect
    when a permit to appropriate is granted, the permit must be conditioned to protect the flows or
    levels.” Postema, 142 Wn.2d at 80 n.2. Swinomish reaffirmed that the relation-back doctrine does
    not apply when appropriation would conflict with MIFs. 178 Wn.2d at 591 n.9 (“[T]he date the
    permit is approved, not the date of application, determines the priority date of the permit to
    appropriate and consequently whether the water right obtained under the permit is subject to the
    minimum flows or levels.”); cf RCW 90.03.340.
    The Dungeness Rule applies to use and appropriation of water in the Dungeness Basin
    “begun after the effective date” of the rule. WAC 173-518-010(3). No provision of the rule
    12
    Although the statutory relation-back doctrine applies specifically to applications for water rights,
    courts have also recognized a common law relation-back doctrine for PE wells. Fox, 193 Wn.
    App. at 276-77; see also Alpowa Creek, 
    129 Wash. at 13
    .
    29
    51221-1-II
    affected any water right previously existing at the time the rule went into effect, including existing
    groundwater rights established through PE wells “where regular beneficial use began before the
    effective date” of the rule. WAC 173-518-010(3)(a), (b).
    The priority date of specific PE wells would depend on a fact-specific inquiry looking to
    both the intention to appropriate and reasonable diligence in applying the water to a beneficial use.
    Fox, 193 Wn. App. at 276-77. However, to the extent any appropriations may interfere with MIFs
    set in the Dungeness Rule, the relation-back doctrine does not apply, pursuant to Postema and
    Swinomish. 142 Wn.2d at 80 n.2; 178 Wn.2d at 591 n.9. Based on the foregoing, the priority date
    for new PE wells that conflict with MIFs is the date when water is first put to a beneficial use.
    C.      COST-BENEFIT ANALYSIS AND LEAST BURDENSOME ALTERNATIVES
    Plaintiffs claim that DOE erred in its CBA and LBA analyses by refusing to consider the
    “cost” of lost legal rights for potential drillers of future PE wells. They claim that DOE erred by
    refusing to assign any value to the “right” to drill a PE well in the Dungeness basin, and thus erred
    by failing to consider the cost of these lost rights in its CBA and LBA. Because the Dungeness
    Rule was not a “significant legislative rule,” DOE was not required to perform a CBA or LBA
    analysis.
    The APA provides a list of procedural requirements state agencies must follow before
    adopting a “significant legislative rule.” RCW 34.05.328(1). These requirements include a
    determination that the probable benefits of the rule are greater than its probable costs and that the
    rule is the least burdensome alternative that will achieve the general goals and specific objectives
    it seeks to accomplish. RCW 34.05.328(1)(d), (e).
    A “significant legislative rule” is one that “adopts substantive provisions of law pursuant
    to delegated legislative authority, the violation of which subjects a violator of such rule to a penalty
    30
    51221-1-II
    or sanction” or that “establishes, alters, or revokes any qualification or standard for the issuance,
    suspension, or revocation of a license or permit.” RCW 34.05.328(5)(c)(iii). The Dungeness Rule
    clearly meets this definition. It adopts numerous substantive provisions of law, including MIFs,
    closure of the basin to new withdrawals, and metering and mitigation requirements. However, the
    WPA provides an exception to the normal definition of “significant legislative rule.”
    Under the WPA, DOE may use an expedited rulemaking process when setting MIFs set in
    accordance with watershed plans. RCW 90.82.080. When utilizing this process, DOE may use
    the standard APA rulemaking process, an expedited APA process, or a process “that uses public
    hearings and notice provided by the county legislative authority to the greatest extent possible.”
    RCW 90.82.080(1)(b). Rules adopted under this section “do not constitute significant legislative
    rules.” RCW 90.82.080(1)(b).
    A “central purpose” of the Elwha-Dungeness Plan was to establish MIFs and the plan
    proposed specific instream flow numbers for numerous streams in the basin, including the
    Dungeness mainstem.        Each MIF established by the Dungeness Rule is identical to the
    recommended MIF proposed in the plan. WAC 173-518-040, Table II.
    The plan also provided many recommendations besides MIFs. It recommended continued
    groundwater withdrawals be conditioned on mitigation to surface water impacts and increased
    regulation of PE wells. It suggested creation of a groundwater reserve to facilitate land use
    planning, managed growth, and protection of instream flows. It also recommended that, for new
    wells, it be made clear “that the date of priority . . . of a water right is the date the water is put to
    beneficial use, not the date the well was drilled.” ECY070408.
    The plan additionally recommended establishment of a “limited groundwater reserve” to
    keep some available water for future appropriation. ECY070402. DOE implemented this
    31
    51221-1-II
    recommendation with its creation of reservations of water for domestic use, not subject to MIFs.
    WAC 173-518-080.
    Both the Plan and the Rule contemplated creation of MIFs, priority dates for PE wells based
    on when water is put to a beneficial use, and establishment of water reserves. To the extent
    plaintiffs have identified minor discrepancies between the Plan and the Rule, the overall character
    and purpose of the rule was still to enact the recommendations of the plan. DOE used the Plan as
    “the foundation” for developing the Rule.13 AR at ECY002041.
    DOE adopted the Dungeness Rule pursuant to its authority to establish MIFs consistent
    with watershed plans under the WPA. Consequently, the Rule is not a “significant legislative rule”
    and DOE was not required to perform a CBA or LBA analysis.
    VI.    ARBITRARY AND CAPRICIOUS
    Finally, plaintiffs claim that the Dungeness Rule is arbitrary and capricious for many of
    the same reasons discussed above. They claim it was arbitrary and capricious because DOE did
    not make maximum net benefits findings, did not consider public interest under the four-part test
    for new appropriations, and appropriated more water for fish than naturally exists in the basin.
    They additionally claim DOE was arbitrary and capricious by foreclosing future domestic use,
    approving a mitigation plan before acquiring year-round mitigation, and “attempt[ing] to make
    new law regarding the priority date of [PE] wells.” Br. of Appellant at 47-48. We disagree.
    Agency action is arbitrary and capricious when “it is willful and unreasoning and taken
    without regard to the attending facts or circumstances.” Wash. Indep. Tel. Ass’n v. Wash. Utils. &
    13
    Specifically, plaintiffs argue that the Rule’s implementation of maximum depletion amounts
    triggering denial of new water uses was nowhere to be found in the Plan. This section of the rule
    is a natural corollary to enforcement of MIFs, one of the central tenets of the Rule and Plan both,
    and does not prevent DOE from exercising its WPA rulemaking authority.

    51221-1-II
    Transp. Comm’n, 
    148 Wn.2d 887
    , 905, 
    64 P.3d 606
     (2003). When “there is room for two opinions,
    an action taken after due consideration is not arbitrary and capricious even though a reviewing
    court may believe it to be erroneous.” Hillis v. Dep’t of Ecology, 
    131 Wn.2d 373
    , 383, 
    932 P.2d 139
     (1997). When a rule is challenged as arbitrary and capricious, “the reviewing court must
    consider the relevant portions of the rule-making file and the agency’s explanations for adopting
    the rule as part of its review.” Wash. Indep. Tel. Ass’n, 148 Wn.2d at 906.
    “When an agency acts within its authority, a rule is presumed to be valid and, therefore,
    the ‘burden of demonstrating the invalidity of agency action is on the party asserting the
    invalidity.’” Wash. Fed’n of State Emps. v. Dep’t of Gen. Admin., 
    152 Wn. App. 368
    , 378, 
    216 P.3d 1061
     (2009) (quoting RCW 34.05.570(1)(a)).
    DOE adopted the Dungeness Rule to “meet statutory obligations to manage waters for
    public use and for the protection of instream flows” and to adopt the recommendations of the
    Elwha-Dungeness Plan. AR at ECY001839. In order to meet these goals, DOE adopted each of
    the provisions laid out above, as well as requiring metering for all water use in the Dungeness
    Basin, establishing maximum depletion amounts to limit adverse impacts caused by new mitigated
    appropriations, and adopting several other water management provisions not raised by plaintiffs.
    Ch. 173-518 WAC.
    As the Elwha-Dungeness Planning Unit and DOE found, “stream flow with existing uses
    is considerably lower than stream flow needed to meet biological needs.” AR at ECY001839. In
    its initial rulemaking order, DOE stated that “adoption of this water management rule is needed to
    protect instream values within the Dungeness watershed, avoid injury to existing water rights from
    future appropriations of water, and implement recommendations of the Elwha-Dungeness
    Watershed Plan.” AR at ECY071270.
    33
    51221-1-II
    Plaintiffs do not cite the record or any authority outside the general standard for arbitrary
    and capricious agency action and two rudimentary water law statues. The burden is on plaintiffs
    to show that the rule is arbitrary and capricious. RCW 34.05.570(1)(a). Here, where they have
    simply reframed their earlier arguments without any citation to authority, plaintiffs have failed to
    meet that burden.
    CONCLUSION
    Plaintiffs have not shown that DOE exceeded its statutory authority in adopting the
    Dungeness Rule, nor that the rule is arbitrary and capricious. We uphold the rule and affirm the
    trial court’s dismissal of the case.
