    WIGGINS, J.-We granted review of this challenge to the Western Washington
    Growth Management Hearings Board's (Board) decision on the validity of Whatcom
    County's (County) comprehensive plan and zoning code under the Growth
    Management Act (GMA or Act), chapter 36.70A RCW. The County argues that the
    Board's conclusions are based on an erroneous interpretation of the law and asks us
    to hold that the County's comprehensive plan protects the quality and availability of
    water as required by the GMA.
    Whatcom County, Hirst (Eric) v: W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    We reject the County's arguments. The GMA requires counties to ensure an
    adequate water supply before granting a building permit or subdivision application.
    The County merely follows the Department of Ecology's "Nooksack Rule"; 1 it assumes
    there is an adequate supply to provide water for a permit-exempt well unless Ecology
    has expressly closed that area to permit-exempt appropriations. This results in the
    County's granting building permits for houses and subdivisions to be supplied by a
    permit-exempt well even if the cumulative effect of exempt wells in a watershed
    reduces the flow in a water course below the minimum instream flow. We therefore
    hold that the County's comprehensive plan does not satisfy the GMA requirement to
    protect water availability and that its remaining arguments are unavailing. We reverse
    the Court of Appeals in part and remand to the Board for further proceedings.
    FACTS
    I.   Factual History
    This case is the latest step in a series of disputes concerning the County's land
    use regulations. The history is only summarized here; a detailed history of the disputes
    is contained in our 2009 opinion, Gold Star Resorts, Inc. v: Futurewise, 
    167 Wash. 2d 723
    , 726-33, 
    222 P.3d 791
    (2009). In Gold Star Resorts, we considered several
    challenges under the GMA to the County's comprehensive plan-specifically,
    challenges to provisions regarding limited areas of more intensive rural development
    and rural densities. We agreed with the Board and directed the County to revise its
    comprehensive plan in order to conform to the 1997 amendments to the GMA. /d. at
    740.

    2
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    In response to our ruling in Gold Star Resorts and a series of subsequent board
    rulings requiring the County to bring its comprehensive plan into compliance with the
    GMA, the County amended its comprehensive plan and zoning code by adopting
    Ordinance No. 2012-032. Ordinance No. 2012-032 was an effort to comply with the
    GMA's requirement that the County's rural element include measures to protect
    surface and groundwater resources. To accomplish this objective, the ordinance
    amended the County's Comprehensive Plan Policies 200-2.C and -2.0, and adopted
    by reference numerous preexisting county regulations. These policies, and the
    regulations they incorporate, were intended to address the GMA requirements to
    protect both water availability and water quality.
    Regarding water availability, the County's development regulations adopt
    Ecology's regulations-the regulations allow a subdivision or building permit applicant
    to rely on a private well only when the well site "proposed by the applicant does not
    fall within the boundaries of an area where [Ecology] has determined by rule that water
    for development does not exist." Whatcom County Code (WCC) 24.11.090(8)(3),
    .160(0)(3), .170(E)(3) 2
    2 Though not related directly to this appeal, the County also took steps to address our
    decisions in Department of Ecology v. Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    , 
    43 P.3d 4
    (2002)
    and Kittitas County v. Eastern Washington Growth Management Hearings Board, 172 Wn .2d
    144, 
    256 P.3d 1193
    (2011 ). Specifically, WCC 21.01.040 requires contiguous parcels of land
    with the same ownership to be considered as one parcel for the purpose of permit-exempt
    water appropriations. The County also adopted policies incorporating regulations and
    programs to protect water quality. These measures include critical area regulations, a storm
    water management program, sewage regulations, and measures designed to protect the
    Lake Whatcom watershed. The Board ruled that the measures designed to protect the Lake
    Whatcom watershed comply with the GMA and these measures are unrelated to this appeal.

    II.      Procedural History
    Eric Hirst, Laura Leigh Brakke, Wendy Harris, David Stalheim, and Futurewise
    (collectively Hirst) filed a petition for review with the Board, challenging Ordinance No.
    2012-032. Relevant to this appeal, Hirst challenged the adequacy of the County's
    measures to protect surface and groundwater resources (Policies 2DD.-2.C.1 through
    .9) and sought a declaration of invalidity. 3
    A. Board's discussion of applicable Jaw
    The Board held a hearing and issued a final decision and order (FDO). The
    Board began its decision by citing to the "Applicable Law" as provided by the GMA.
    As the Board observed, the GMA imposes several requirements on a local
    government's planning. Relevant here, the GMA requires counties to consider and
    address water resource issues in land use planning. Kittitas County v. E. Wash.
    Growth Mgmt. Hr'gs Bd., 
    172 Wash. 2d 144
    , 178, 
    256 P.3d 1193
    (2011) (counties must
    regulate to ensure land use is not inconsistent with available water resources).
    Accordingly, a county's comprehensive plan must '"provide for protection of the quality
    and quantity of groundwater used for public water supplies."' FDO at 13 (emphasis
    omitted) (quoting RCW 36.70A.070(1 )). The GMA also requires counties to plan for a
    rural element that "'include[s] measures that ... protect ... surface water and
    groundwater           resources."'   /d.   at   14   (emphasis   omitted)   (quoting   RCW
    36. 70A.070(5)(c)(iv)).
    3  Hirst also asserted, unsuccessfully, that the County's transportation element was
    inconsistent with its rural element in violation of RCW 36. 70A.070 or RCW 36. 70A.130; this
    issue is not before us on appeal.
    4
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    The Board also noted that counties must include a rural element in their
    comprehensive plan that includes "'lands that are not designated for urban growth,
    agriculture, forest, or mineral resources."' /d. at 13 (quoting RCW 36.70A.070(5)). The
    County's comprehensive plan must ensure that this rural element maintains its
    "'[r]ural character'" by planning its land use and development in a manner that is
    "'compatible with the use of the land by wildlife and for fish and wildlife habitat"' and
    "'[t]hat are consistent with the protection of natural surface water flows and
    groundwater and surface water recharge and discharge areas."' /d. (emphasis
    omitted) (quoting RCW 36.70A.030(15)(d), (g)).
    In addition to these planning requirements, the Board noted that the GMA
    provides 13 goals to guide the development of a county's comprehensive plan. These
    include a goal to "'[p]rotect the environment and enhance the state's high quality of
    life, including air and water quality, and the availability of water."' /d. (emphasis
    omitted) (quoting RCW 36.70A.020(1 0)). These goals "are not listed in order of priority
    and shall be used exclusively for the purpose of guiding the development of
    comprehensive plans and development regulations." RCW 36.70A.020. Read
    collectively, these goals convey some conceptual guidance for growth management.
    Richard J. Settle, Washington's Growth Management Revolution Goes to Court, 23
    SEATTLE U. L. REV. 5, 8 (1999).
    The Board interpreted these planning requirements and goals to indicate that
    patterns of land use and development in rural areas must be consistent
    with protection of instream flows, groundwater recharge, and fish and
    wildlife habitat. A County's Comprehensive Plan rural lands provision
    5
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    must include measures governing rural development to protect water
    resources.
    FDO at 21.
    The GMA does not define the requirements to plan for the protection of water
    resources found in RCW 36.70A.070. The Act also fails to define how the
    requirements are to be met. Thus, Hirst argued that the County's comprehensive plan
    must itself protect the availability of water resources, placing the burden on local
    governments to protect the availability of water, RCW 36.70A.020(10), protect
    groundwater resources, RCW 36.70A.070(5)(c)(iv), and ensure an adequate water
    supply when it approves a building permit, RCW 19.27.097(1) and RCW 58.17.110.
    The County countered that it complied with the GMA by drafting a comprehensive plan
    that incorporates and is consistent with Ecology's regulations in water resource
    inventory area (WRIA) 1. 4 In evaluating this relationship between Ecology's
    responsibility to protect water pursuant to the Water Resources Act of 1971 (WRA),
    chapter 90.54 RCW, and the responsibility of local governments to protect water
    availability and quality pursuant to the GMA, the Board stated that "it is the local
    government-and not Ecology-that is responsible to make the decision on water
    adequacy as part of its land use decision, and in particular, with respect to exempt
    wells." FDO at 23.
    4  WRIAs establish instream flows affecting the approval of water rights permits and
    appropriations for most of the state; WRIA 1 is in effect in the County. See ch. 173-501 WAC
    (the Nooksack Rule). There are now 62 WRIAs designated, described, and subject to the
    rules promulgated by Ecology. See generally chs. 173-501 to -564 WAC. Though specific
    rules apply to each of these WRIAs, they generally share the purpose of retaining "perennial
    rivers, streams, and lakes in [the WRIAs] with in stream flows and levels necessary to provide
    for preservation of wildlife, fish, scenic, aesthetic, and other environmental values, and
    navigational values, as well as recreation and water quality." WAC 173-501-020.

    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    B. Board's findings and conclusions on water quality and availability
    Hirst presented considerable evidence and the Board found substantial
    evidence of limits on water availability in rural Whatcom County. See 
    id. at 23-28.
    These water availability limitations were reflected in findings that a large portion of the
    County is in year-round or seasonally closed watersheds and that most of the water
    in the Nooksack watershed was already legally appropriated. /d. at 23-34. The Board
    also found that average minimum instream flows in portions of the Nooksack River
    "are not met an average of 100 days a year." /d. at 24. Despite the limited water
    availability, 1 ,652 permit-exempt well applications have been drilled in otherwise
    closed basins since 1997 and an additional 637 applications were pending in March
    2011. /d. Further, the Board noted that the County recognized as early as 1999 that
    this proliferation of rural, permit-exempt wells was creating '"difficulties for effective
    water resource management."' /d. (quoting Ex. C-671-D at 49 (1999 Whatcom County
    Water Resource Plan)).
    The Board concluded that the County failed to comply with the GMA,
    specifically with the requirement to protect surface water and groundwater resources
    pursuant to RCW 36.70A.070(5)(c). The Board's conclusion that the comprehensive
    plan does not protect water availability is predicated on the Board's finding that
    the water supply provisions referenced [by the amended policies] do not
    require the County to make a determination of the legal availability of
    groundwater in a basin where instream flows are not being met.
    FDO at 40. Implicit in this conclusion is the Board's determination that water is not
    presumptively available for permit-exempt withdrawals in WRIA 1. However, despite
    concluding that the comprehensive plan does not protect water availability or water
    7
    Whatcom County, Hirst (Eric)      v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    quality, the Board denied Hirst's request for a declaration of invalidity and instead
    remanded the ordinance to the County to take corrective action.
    Both parties appealed separately. The County's appeal, focusing exclusively on
    its measures to protect ground and surface water resources, challenged the Board's
    determination of noncompliance with the GMA. Hirst challenged the Board's decision
    not to declare the ordinance invalid. The cases were consolidated in Skagit County
    Superior Court, and the Board issued its certificate of appealability of the FDO,
    certifying the consolidated appeals for direct review to the Court of Appeals. Following
    the County's appeal of a second order of compliance issued by the Board in April
    2014, the Court of Appeals granted review. Its review consolidated that appeal, the
    prior consolidated appeals for direct review, and the County's motion for discretionary
    review of the original FDO.
    The Court of Appeals reversed the Board, holding that the Board erroneously
    interpreted and applied the law in holding that the ordinance failed to comply with the
    GMA. The Court of Appeals further held that the Board engaged in unlawful procedure
    by taking official notice of and relying on two documents without first providing the
    County notice and the opportunity to contest the documents. The Court of Appeals
    affirmed the Board's decision not to declare the ordinance invalid, holding that the
    decision was a proper exercise of the Board's discretion. 5
    5 As an initial matter, we reject Hirst's argument that the County's failure to assign error to the
    Board's findings of fact by number renders these findings verities on appeal. We affirm the
    Court of Appeals on this issue, noting that the Board did not specifically delineate findings of
    fact by number; instead, it produced a blend of factual findings and legal conclusions. See
    FDO at 23-44. As the Court of Appeals properly found, "the nature and extent of the County's
    challenges to [the findings of fact] are clear. Thus, this court's review is not in any way
    8
    Whatcom County, Hirst (Eric) v. IN. Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    We granted review and now reverse the Court of Appeals in part.
    ANALYSIS
    The County argues that the Board's conclusions are based on an erroneous
    interpretation of the law. RCW 34.05.570(3)( d). Though there are several arguments
    raised in the County's appeal of the Board's decision, the appeal focuses on the
    subject of water availability. This principal issue concerns the actions local growth
    management planners and administrators must take to ensure water availability under
    the GMA.
    Consistent with the Board's determination, Hirst asserts that the GMA requires
    local governments to determine water availability as part of its land use decision. They
    argue that the County's plan does not require the County to obtain evidence that water
    is legally available before issuing building permits or approving subdivisions that rely
    on permit-exempt appropriations. Thus, Hirst asserts that the comprehensive plan
    results in water withdrawals that impact minimum in stream flows.
    The County responds that its comprehensive plan protects the availability of
    water because it ensures that the County will approve a subdivision or building permit
    application that relies on a permit-exempt well for its water supply only when the
    proposed well "does not fall within the boundaries of an area where [Ecology] has
    determined by rule that water for development does not exist." wee 24.11.090(B)(3),
    hindered by the absence of formal assignment of error. Whatcom County v. W Wash. Growth

    Whatcom County, Hirst (Eric)       v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    .160(0)(3), .170(E)(3). In effect, the County's position is that water is presumptively
    available-i.e., that "not unavailable" is synonymous with "available."
    In effect, the County delegates the decision on water availability to Ecology's
    Nooksack Rule, chapter 173-501 WAC. The Nooksack Rule establishes minimum
    instream flows for WRIA 1, covering most of the County. However, the County
    argues-and Ecology agrees-that the closures and minimum flow requirements
    established by the rule are not applicable to permit-exempt wells in the County. Thus,
    the County argues that its comprehensive plan complies with the GMA requirements
    because water is presumptively available in the County for permit-exempt wells. The
    County asserts that under the GMA, the proper inquiry is whether its comprehensive
    plan is consistent with Ecology's regulations designed to protect water and to ensure
    that water is legally available.
    We reject these arguments in the context of the GMA challenge before us. The
    GMA places an independent responsibility to ensure water availability on counties, not
    on Ecology. To the extent that there is a conflict between the GMA and the Nooksack
    Rule, the later-enacted GMA controls.
    Ecology adopted the Nooksack Rule in 1985, and the rule has not been
    amended. We have since recognized that "Ecology's understanding of hydraulic
    continuity has altered over time, as has its use of methods to determine hydraulic
    continuity and the effect of groundwater withdrawals on surface waters." Postema v.
    Pollution Control Hr'gs Bd., 
    142 Wash. 2d 68
    , 76, 
    11 P.3d 726
    (2000). When Ecology
    adopted the minimum instream flow rules, such as those contained within the
    Nooksack Rule, it "did not believe that withdrawals from deep confined aquifers would
    10
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    have any impact on stream flows." /d. at 88. However, we now recognize that
    groundwater withdrawals can have significant impacts on surface water flows, and
    Ecology must consider this effect when issuing permits for groundwater appropriation.
    /d. at 80-81.
    We hold that the same standard applies to counties when issuing building
    permits and subdivision approvals. We have been protective of minimum instream
    flow rules and have rejected appropriations that interfere with senior instream flows.
    E.g., Swinomish Indian Tribal Cmty. v: Dep't of Ecology, 
    178 Wash. 2d 571
    , 598, 
    311 P.3d 6
    (2013); Foster v. Dep't of Ecology, 
    184 Wash. 2d 465
    , 
    362 P.3d 959
    (2015). Our
    jurisprudence and well-established principles of statutory interpretation lead us to
    affirm the Board's decision that the County's comprehensive plan does not satisfy the
    GMA requirement to protect water availability.
    I.   Standard of Review
    The Washington Administrative Procedure Act, chapter 34.05 RCW, governs
    judicial review of challenges to board actions. Quadrant Corp. v: Cent. Puget Sound
    Growth Mgmt. Hr'gs Bd., 154 Wn.2d 224,233, 
    110 P.3d 1132
    (2005). Though county
    actions are presumed compliant, this deference "is neither unlimited nor does it
    approximate a rubber stamp." Swinomish Indian Tribal Cmty. v: W Wash. Growth
    Mgmt. Hr'gs Bd., 161 Wn.2d 415,435 n.8, 
    166 P.3d 1198
    (2007). Instead, deference
    to counties remains "bounded ... by the goals and requirements of the GMA." King
    County v: Cent. Puget Sound Growth Mgmt. Hr'gs Bd., 
    142 Wash. 2d 543
    , 561, 
    14 P.3d 133
    (2000). Further, we do not afford counties any deference when it comes to
    interpreting the GMA. Kittitas 
    County, 172 Wash. 2d at 156
    (citing Lewis County v. W
    11
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    Wash. Growth Mgmt. Hr'gs Bd., 157Wn2d 488,498,139 P.3d 1096 (2006). On appeal
    to this court, the County retains the burden of establishing that the Board's decision is
    based on an erroneous interpretation of the law. King 
    County, 142 Wash. 2d at 553
    .
    The Board must find compliance "unless it determines that the action by the state
    agency, county, or city is clearly erroneous in view of the entire record before the board
    and in light of the goals and requirements of [the GMA]." RCW 36.70A.320(1 ), (3). To
    find an action clearly erroneous, the Board must be "'left with the firm and definite
    conviction that a mistake has been committed."' King 
    County, 142 Wash. 2d at 552
    (quoting
    Dep't of Ecology   v. Pub. Uti/. Oist. 1 of Jefferson County, 
    121 Wash. 2d 179
    , 201, 
    849 P.2d 646
    (1993)). We review the Board's legal conclusions de novo, giving substantial weight
    to the Board's interpretation of the GMA. /d. at 553.
    We review questions of statutory interpretation de novo. Ass'n of Wash. Spirits

    182 Wash. 2d 342
    , 350, 
    340 P.3d 849
    (2015). Our fundamental purpose in statutory interpretation is to ascertain and discern
    the legislature's intent. Dep't of Ecology v: Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    , 9,
    
    43 P.3d 4
    (2002). The court discerns legislative intent from the plain language enacted
    by the legislature, considering the text of the provision in question, the context of the
    statute in which the provision is found, related provisions, amendments to the
    provision, and the statutory scheme as a whole. /d. at 9-19. These rules of statutory
    interpretation also apply to administrative rules and regulations. See Overlake Hasp.
    Ass'n v. Dep't of Health, 
    170 Wash. 2d 43
    , 51-52, 
    239 P.3d 1095
    (201 0).
    The dissent ignores these important rules of statutory interpretation, and
    focuses solely on a single statute in isolation from its relevant GMA statutory scheme.

    Dissent at 2-6 (discussing RCW 19.27.097). As a result, the dissent reaches a
    conclusion about the meaning of this statute that is at odds with our jurisprudence on
    statutory interpretation and with the GMA's larger structure, overarching goals, and
    requirements.
    II.      The Board Correctly Ruled That the County's Rural Element Fails To Comply
    with the Requirement To Protect Water Availability
    We reverse the Court of Appeals and hold that the Board properly interpreted
    and applied the law in concluding that the County's comprehensive plan fails to
    provide for the protection of water resources. The Board's decision properly placed
    the burden on the County to ensure the availability of water under the GMA pursuant
    to the legislative intent, relevant statutory schemes when read in context and as a
    whole, and this court's jurisprudence considering groundwater appropriations that
    impact minimum flows.
    A. Washington's history of water regulation
    We hold that the County's comprehensive plan does not protect water
    availability because it allows permit-exempt appropriations to impede minimum flows.
    In reaching this holding, we note that minimum flows are exactly that: flows or levels
    "to protect instream flows necessary for fish and other wildlife, recreation and
    aesthetic purposes, and water quality." Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 592
    . By statute, the only exception to these flows is found at RCW 90.54.020(3) and,
    though this case does not implicate this exception, we have been extremely protective
    of withdrawals pursuant to that statute. See id.; Foster, 
    184 Wash. 2d 465
    . As scientific
    understanding of water resources has increased, so too have Washington's
    13
    Whatcom County, Hirst (Eric) v. W. Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    restrictions on the availability of water. Washington's original water code, chapter
    90.03 RCW, was enacted in 1917 and regulated only surface water appropriations. In
    1945, the legislature passed the groundwater code to subject the withdrawal of
    groundwater to the permitting process then applicable to surface water rights in order
    to protect senior water rights and the public welfare. See RCW 90.44.020; RCW
    90.03.290(3). Specified withdrawals were exempt from these permit requirements:
    [A]ny withdrawal ... for single or group domestic uses in an amount not
    exceeding five thousand gallons a day ... is and shall be exempt from
    the provisions of this section, but, to the extent that it is regularly used
    beneficially, shall be entitled to a right equal to that established by a
    permit issued under the provisions of this chapter.
    RCW 90.44.050. These permit-exempt withdrawals are appropriations. Swinomish
    Indian Tribal 
    Cmty., 178 Wash. 2d at 588
    . Recognizing that any withdrawal of water
    impacts the total availability of water, we have held that an appropriator's right to use
    water from a permit-exempt withdrawal is subject to senior water rights, including the
    minimum flows established by Ecology. See Campbell & 
    Gwinn, 146 Wash. 2d at 16
    ;
    Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 598
    . These exemptions existed in part
    because the legislature's goal in 1945 was to encourage the development and
    settlement of rural family farms drawing between 200 and 1,500 gallons of water per
    day. Five Corners Family Farmers v. State, 
    173 Wash. 2d 296
    , 321-22, 
    268 P.3d 892
    (2011) (Wiggins, J., dissenting) (citing Kara Dunn, Got Water? Limiting Washington's
    Stockwatering Exemption to Five Thousand Gallons Per Day, 83 WASH. L. REV. 249,
    258 (2008)).
    These legislative priorities continued to change as Washington's population
    increased and the limitations on its natural resources became more apparent. See
    14
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 592
    ("Growing, competing demands for
    water led to a number of new laws over time, and among these are acts and statutes
    designed to further the goal of retaining sufficient water in streams and lakes to sustain
    fish and wildlife, provide recreational and navigational opportunities, preserve scenic
    and aesthetic values, and ensure water quality."). "In 1955, the legislature declared
    the policy of the State to be that sufficient water flow be maintained in streams to
    support fish populations and authorized rejection of water right applications if these
    flows would be impaired." /d. (citing LAWS OF 1955, ch. 12, § 75.20.050 (codified as
    amended at RCW 77.57.020)).
    The legislature continued to enact measures to protect the flows necessary for
    fish, wildlife, and water quality with the minimum water flows and levels act of 1969,
    chapter 90.22 RCW. In part, this act authorized Ecology to "establish minimum water
    flows ... for the purposes of protecting fish, game, birds, or other wildlife resources,
    or recreational or aesthetic values of said public waters whenever it appears to be in
    the public interest." RCW 90.22.01 0. Once established, minimum flows are like any
    other appropriative water right in that they are subject to the rule of "first in time is the
    first in right." Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 591
    .
    The WRA was intended to ensure adequate water to "meet the needs of the
    state's growing population" while concurrently maintaining "instream resources and
    values." RCW 90.54.01 0(1 )(a). To balance growth and stream maintenance, the WRA
    directed Ecology to allocate waters in a way that maximizes the net benefits to the
    people of the state and to retain "base flows necessary to provide for preservation of
    wildlife, fish, scenic, aesthetic and other environmental values, and navigational
    15
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    values." RCW 90.54.020(3)(a). Included in this mandate is the authority to establish
    minimum water flows and water levels (RCW 90.03.247 and RCW 90.22.010), base
    flows, and WRIAs. RCW 90.54.040. At this time, the legislature also made Ecology
    the primary administrator of chapter 90.03 RCW, concerning surface waters, and of
    chapter 90.44 RCW, concerning groundwater. See ch. 43.27A RCW.
    By 1979, however, "public policy had dramatically changed from what had been
    true when the water code was first enacted." Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 595
    . Replacing the 1917 policies encouraging "maximum diversion of water"
    were the modern policies of "[o]btaining maximum benefits, prudent management of
    the state's water resources with input of interested entities, preservation of water
    within the streams and lakes as necessary for instream and natural values, and
    avoidance of wasteful practices." /d. at 595-96.
    In order to obtain the maximum benefit from the state's water resources, the
    legislature tasked Ecology with developing WRIAs. RCW 90.54.040(1 ), (2). Beginning
    in 1985, Ecology developed the Nooksack Rule (WRIA 1), the first of 62 WRIAs
    designated, described, and subject to rules promulgated by Ecology. See generally
    chs. 173-501 to 173-564 WAC. Though specific rules apply to each of these WRIAs,
    see 
    id., they generally
    share the purpose "to retain perennial rivers, streams, and
    lakes in [the WRIAs] with instream flows and levels necessary to provide for
    preservation of wildlife, fish, scenic, aesthetic, and other environmental values, and
    navigational values, as well as recreation and water quality." WAC 173-501-020; see
    also RCW 90.54.020(3).
    16
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    In 1990 and 1991, the legislature addressed issues related to water use when
    it enacted the GMA '"in response to public concerns about rapid population growth
    and increasing development pressures in the state."' King 
    County, 142 Wash. 2d at 546
    (quoting Alan D. Copsey, Including Best Available Science in the Designation and
    Protection of Critical Areas Under the Growth Management Act, 23 SEATTLE U. L. REV.
    97 (1999)). This legislation followed "decades of lax and optional land use
    regulations." Quadrant 
    Corp., 154 Wash. 2d at 232
    . Through the GMA, the legislature
    sought to minimize "uncoordinated and unplanned growth," which it found to "pose a
    threat to the environment, sustainable economic development, and the health, safety,
    and high quality of life enjoyed by residents of this state." RCW 36.70A.01 0.
    Importantly, the GMA concentrates future growth into urban growth areas. See
    RCW 36. 70A.11 0. Through this requirement, "the Act seeks to minimize intrusion into
    resource lands and critical areas, preserve large tracts of open space easily
    accessible to urban residents, foster a sense of spatial identity by separating
    communities with great expanses of sparsely populated rural land, and induce
    sufficient development density to be efficiently served by mass transportation and
    other public facilities." 
    Settle, supra
    , 23 SEATTLE U. L. REV. at 12. Put another way, the
    Act concentrates development in cities and discourages development and will
    "attempt to wean Washingtonians from the sprawling, low-density development
    patterns that have prevailed throughout the nation since World War II." /d. at 12-13.
    The GMA reinforces the conservation goals and priorities first established in the
    WRA by requiring local governments to plan for the protection of their local
    environment. The GMA requires counties to adopt a comprehensive plan and
    17
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    development regulations consistent with the comprehensive plan. See RCW
    36.70A.040. Among other requirements, comprehensive plans must include a rural
    element that harmonizes the Act's goals with local circumstances and also protects
    the rural characteristics of the area. See RCW 36.70A.070(5)(a), (c). Protecting the
    rural character of the area requires planning to protect surface and groundwater
    resources. RCW 36.70A.070(5)(c)(iv).
    B. The GMA requires counties to have a comprehensive plan that protects
    surface and groundwater resources
    We hold that the Board properly concluded that the GMA requires counties to
    make determinations of water availability. The language placing this burden on the
    county or local government is clear, consistent, and unambiguous throughout the Act.
    We begin with the plain language of the statute. Ass'n of Wash. Spirits & Wine
    
    Distribs., 182 Wash. 2d at 350
    . When the language is clear, we look only to the wording
    of the statute. W Telepage, Inc. v. City of Tacoma Dep't of Fin., 
    140 Wash. 2d 599
    , 609,
    
    998 P.2d 884
    (2000). The language of chapter 36.70A RCW, entitled "Growth
    Management-Planning by Selected Counties and Cities," is clear. RCW 36.70A.040,
    "Who must plan-Summary of Requirements," provides in part:
    (1) Each county [subject to the Act] shall conform with all of the
    requirements of [chapter 36.70A RCW].
    Subsection .040(3) outlines the duties of the county's legislative authority and each
    city located within the county to conform to the Act's mandates, starting with
    "adopt[ing] a countywide planning policy under RCW 36.70A.21 0," and then places
    specific duties on the county. This language clearly requires the county legislative
    authority-and    not Ecology-to take planning        action,   including   adopting   a
    18
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    comprehensive plan.
    Language placing the burden on counties to take action is consistent
    throughout the GMA. "Counties shall include a rural element" in their comprehensive
    plans. RCW 36.70A.070(5). These rural elements must protect the rural character of
    the area "as established by the county." RCW 36.70A.070(5)(c). The GMAalso places
    the onus on counties to ensure that their development regulations and comprehensive
    plans comply with the GMA. RCW 36. 70A.130( 1)(a) ("a county or city shall ... ensure
    the plan and regulations comply with the requirements of this chapter.").
    The GMA requires counties to consider and address water resource issues in
    land use planning. Specifically, a county's comprehensive plan must "provide for
    protection of the quality and quantity of groundwater used for public water supplies."
    RCW 36. 70A.070(1 ). The GMA also requires counties to plan for a rural element that
    "include[s] measures that ... protect ... surface water and groundwater resources."
    RCW 36.70A.070(5)(c)(iv). Read as a whole, it is clear that the GMA holds counties
    "responsible for land use decisions that affect groundwater resources." Kittitas
    
    County, 172 Wash. 2d at 180
    .
    C. The County's comprehensive plan conflicts with the GMA
    The GMA requires that an applicant for a building permit for a single family
    residence or a development must produce proof that water is both legally available
    and actually available. But the County does not require any showing that water is
    available for a building permit when the applicant is relying on permit-exempt water
    appropriation. This failure by the County is the crux of this case.
    The GMA places specific requirements on local governments when approving
    19
    Whatcom County, Hirst (Eric)    v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    building   permits or authorizing subdivisions.        See RCW 19.27.097(1 );         RCW
    58.17.110(2). 6 In order to comply with the GMA, counties must receive sufficient
    evidence of an adequate water supply from applicants for building permits or
    subdivisions before the county may authorize development. RCW 19.27.097(1)
    provides in relevant part:
    Each applicant for a building permit of a building necessitating potable
    water shall provide evidence of an adequate water supply for the
    intended use of the building.
    In addition, RCW 58.17.110(2} provides:
    A proposed subdivision and dedication shall not be approved unless the
    city, town, or county legislative body makes written findings that: (a)
    Appropriate provisions are made for ... potable water supplies ....
    Through these statutes, the GMA requires counties to assure that water is both
    factually and legally available. Kittitas 
    County, 172 Wash. 2d at 179-80
    .
    The dissent focuses solely on the text of RCW 19.27.097 and concludes that
    "adequate," as the term is used in the statute, requires a permit applicant to
    demonstrate that water is merely factually available. This narrow interpretation of
    "adequate" ignores our discussion in Kittitas County and fails to appreciate the larger
    GMA scheme. In Kittitas County, we rejected the argument that the GMA required only
    6 The dissent places undue significance on RCW 19.27.097's location within the state building
    code. Dissent at 3-4. Though contained within Titles 19 and 58 RCW, both RCW 19.27.097
    and 58.17.110(2) are part of the GMA. The legislature enacted the GMAin 1990 and amended
    the GMA in 1991. RCW 19.27.097 was in the 1990 act and amended in 1991. See LAws OF
    1990, 1st Ex. Sess., ch. 17, § 63; LAWS OF 1991, Spec. Sess., ch. 32, § 28. RCW 58.17.110(2)
    was amended by the 1990 act. See LAWS OF 1990, ch. 17, §52. While the dissent correctly
    notes that RCW 19.27.097 contains separate requirements for GMA and non-GMA counties,
    this does not give this court grounds to ignore the rest of the GMA. We must read RCW
    19.27.097 in conjunction with the larger GMA statutory scheme of which it is a part. See
    Campbell & 
    Gwinn, 146 Wash. 2d at 9-11
    .
    20
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    a showing of factual availability in order to obtain a building permit from the county.
    /d. Instead, we held that the GMA requires counties to "plan for land use in a manner
    that is consistent with the laws regarding protection of water resources." /d. at 180.
    Were we to read the GMA to require counties to assure merely that "water is physically
    underground," it would allow the county to condone the evasion of existing water
    rights, contrary to law. /d.
    Further, because the dissent fails to read this statute in conjunction with related
    provisions within the GMA, the dissent ignores the responsibility the GMA places on
    counties to protect groundwater resources under RCW 36.70A.070. When read as a
    whole, the GMA places the burden on counties to protect groundwater resources, and
    requires counties to assure that water is both factually and legally available before
    issuing building permits. 7
    Here, the County's existing comprehensive plan does not require the County to
    make a determination of water availability. Instead, the comprehensive plan relies on
    determinations of water availability provided by Ecology's Nooksack Rule, chapter
    173-501 WAC.
    The Nooksack Rule establishes minimum flows for 48 basins in WRIA 1,
    covering the County. WAC 173-501-030. Most of the 48 basins are closed, and over
    half of the basins are closed year-round because they are already overdrawn. See
    WAC 173-501-040; see a/so BECKY PETERSON ET AL., 2010 WRIA 1 STATE OF THE
    7
    The dissent notes that this interpretation of RCW 19.27.097 may result in differences
    between GMA and non-GMA counties in the level of protection for water rights holders.
    However, the legislature has created a distinction between GMA counties and non-GMA
    counties, and the resulting differences in resource management between those counties is a
    natural consequence of this legislation.
    21
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    WATERSHED REPORT 10 (2011). However, the Nooksack Rule establishes two tiers of
    "closed" basins in WRIA 1: basins closed to all appropriations except permit-exempt
    appropriations and basins closed to all appropriations including permit-exempt
    appropriations. See WAC 173-501-040(1 ), -070(2). Despite significant evidence that
    minimum flows are not met in rural Whatcom County, Whatcom Creek is the only
    basin-out of 48 basins in WRIA 1-closed to permit-exempt appropriations. WAC
    173-501-070. Thus, the Nooksack Rule does not restrict permit-exempt wells from
    appropriating water in otherwise closed basins.
    The County interprets the Nooksack Rule to mean that water is actually
    available for permit-exempt appropriations in otherwise closed basins, even if the
    basin is closed because the watercourses fall below minimum flows during all or parts
    of the year. The Board correctly rejected this interpretation. The Board found that
    despite substantial evidence of impaired instream flows, the County continues to
    authorize development relying on permit-exempt groundwater appropriations in
    otherwise closed basins. FDO at 42. The County's deference to the Nooksack Rule
    as a substitute for an actual determination of water availability expressly allows permit-
    exempt appropriations to interfere with established minimum flows because the
    Nooksack Rule exempts these appropriations from minimum flow requirements. See
    WAC 173-501-030(3), -060, -070(2). The result is an unchecked reduction of minimum
    flows unless and until Ecology closes a basin to all future appropriations. See WAC
    173-501-070(2).
    In ruling that the County's comprehensive plan does not provide for the
    protection of water availability, the Board specifically found amended rural element
    22
    Whatcom County, Hirst (Eric)     v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    policies 2DD-2.C.6 and -2.C.7 noncompliant with the GMA. These policies incorporate
    provisions of the WCC. 8 In turn, the incorporated provisions of the WCC defer to the
    Nooksack Rule by excluding the permit-exempt groundwater appropriations from the
    need to demonstrate water availability and by authorizing permit-exempt groundwater
    appropriations in otherwise closed basins. See WCC 24.11.090(B)(3) (the director will
    approve an application for a permit-exempt water appropriation only if the
    appropriation "does not fall within the boundaries of an area where [Ecology] has
    determined by rule that water for development does not exist"), .160(0)(3) (same),
    .170(E)(3) (same).
    These policies are contrary to the requirements of the GMA. As noted,
    amended rural element policies 2DD-2.C.6 and -2.C.7 specifically incorporate             wee
    21.04.090,    wee    21.05.080(3), and    wee      24.11.050, which are   wee    provisions
    governing public and private water systems. Each of these ordinances requires an
    applicant for a public or private water system to make a showing of water availability
    to withdraw more than a total of 5,000 gallons per day. But as the Board noted at page
    8   Whatcom County Comprehensive Plan policy 2DD-2.C.6:
    Limit water withdrawals resulting from land division through the standards in the
    following Whatcom County Land Division regulations, adopted herein by
    reference:
    a.     WCC 21.04.090 Water supply, Short Subdivisions
    b.     WCC 21.05.080 Water supply, Preliminary Long Subdivisions.
    Whatcom County Comprehensive Plan policy 2DD-2.C.7:
    Regulate groundwater withdrawals by requiring purveyors of public water systems
    and private water system applicants to comply with Washington State Department
    of Ecology ground water requirements per WCC 24.11.050, adopted herein by
    reference.
    23
    Whatcom County, Hirst (Eric) v. W. Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    42 of the FDO, "ultimately, a building permit for a private single-residential well does
    not require the applicant to demonstrate that groundwater withdrawal will not impair
    surface flows."
    Indeed, the County's rules for approving permit-exempt applications authorize
    groundwater appropriations in otherwise closed basins. The County asserts that its
    comprehensive plan protects surface flows because it provides that the director will
    approve an application for a permit-exempt water appropriation only if the
    appropriation "does not fall within the boundaries of an area where [Ecology] has
    determined by rule that water for development does not exist." WCC 24.11.090(B)(3),
    .160(0)(3), .170(E)(3). In effect, these ordinances provide that the County determines
    water availability by referencing the minimum flows and basin closures established by
    the Nooksack Rule. The problem is that the Nooksack Rule-including the minimum
    flows and closed basins established by the rule-does not regulate or otherwise
    restrict permit-exempt uses. See WAC 173-501-070(2). The County thus reasons that
    water is always available for permit-exempt appropriations. In reality, the County's
    incorporation of the Nooksack Rule authorizes              permit-exempt groundwater
    appropriations that draw from minimum flows and otherwise closed basins, setting up
    a conflict with the County's obligation to protect water availability under the GMA.
    D. The County's plan fails to protect the availability of water resources
    Recognizing the conflict between the GMA and the Nooksack Rule, the Board
    properly held the County to the requirements imposed by the GMA. The Board ruled
    that policy 2DD-2.C.7 does not comply with the requirements of the GMA because
    under the policy, "a building permit for a private single-residential well does not require
    24
    Whatcom County, Hirst (Eric)    v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    the applicant to demonstrate that groundwater withdrawal will not impair surface
    flows." FDO at 42. This violates the requirement in RCW 19.27 .097(1) that applicants
    "for a building permit of a building necessitating potable water shall provide evidence
    of an adequate water supply." See also RCW 58.17.110(2) (proposed subdivisions
    shall not be approved without evidence of adequate potable water). Further, the Board
    found that policy 2DD-2.C.7 "fails to limit rural development to protect ground or
    surface waters with respect to permit-exempt wells as required                    by RCW
    36.70A.070(5)( c)(iv)." FDO at 42.
    As discussed in Section II.B of this 
    opinion, supra
    , the County's policies
    incorporate   wee   provisions that do not allow water to be withdrawn from "an area
    where [Ecology] has determined by rule that water for development does not exist."
    WCC 24.11.090(B)(3), .160(0)(3), .170(E)(3). As counsel conceded at oral argument,
    these ordinances further provide that an application for a permit-exempt appropriation
    will be approved without any analysis of that withdrawal's impact on instream flows. 9
    The Board found that these provisions result in water withdrawals from closed basins
    and senior instream flows-flows that the record indicated drop below the minimum
    levels 100 days out of the year. The Board properly held that this conflicts with the
    requirement placed on counties to protect water availability under the GMA, as well
    as our holding in Postema,

    10 The dissent relies on a 1992 attorney general opinion (AGO) to support its conclusion that

    do not read the AGO to support this conclusion. Rather, the AGO recognizes that in order to
    25
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    The County's adoption of the Nooksack Rule with its presumption that water is
    available for permit-exempt appropriations fails to satisfy the protective purposes and
    requirements of the GMA. As Ecology acknowledges in its amicus briefing, the
    Nooksack Rule is "[b]ased on the scientific understanding [in 1985, when] Ecology
    determined that only limited instances would occur in which groundwater withdrawals
    might impair instream flows." Ecology's Amicus Curiae Br. at 19-20. But "Ecology's
    understanding of hydraulic continuity has altered over time," and the effects of
    groundwater withdrawals on surface waters are well known. 
    Postema, 142 Wash. 2d at 76
    . Indeed, the County knew in 1999 that the proliferation of rural, permit-exempt wells
    was creating '"difficulties for effective water resource management."' FDO at 24
    (quoting Ex. C-671-D at 49). The County cannot reasonably rely on this regulation to
    satisfy its responsibility under the GMA to protect water availability.
    Indeed, the County's reliance on the Nooksack Rule turns the GMA goal of
    directing growth to urban areas upside down. The County's comprehensive plan
    allows the unchecked growth of single domestic dwellings relying on permit-exempt
    assure "adequate" water supply, a local county requires proof of both sufficient quantity and
    quality before issuing a building permit. 1992 Op. Att'y Gen. No. 17, at 7. Additionally, the
    AGO recognizes due to our state's "first in time, first in right" water priority system, a local
    building authority might have to require more than a right to withdraw groundwater by Ecology
    permit or exemption in order to meet the "adequacy" requirement, and might require proof of
    legal availability. See 
    id. at 11
    n.5. However, the AGO fails to fully consider counties'
    responsibilities under the GMA when permit-exempt wells impede minimum flows. While we
    give opinions of the attorney general considerable weight, they are not controlling on this
    court. Wash. Fed'n of State Emps. v. Office of Fin. Mgmt., 
    121 Wash. 2d 152
    , 164, 
    849 P.2d 1201
    (1993). Further, we give less deference to such opinions when they involve issues of
    statutory interpretation. /d. While the AGO is not inconsistent with our decision today, we
    decline to give it weight or consideration here because we find it of limited application to the
    specific facts of this case, and because it fails to interpret RCW 19.27.097 within the larger
    GMA statutory scheme.
    26
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    wells in rural areas; this is precisely the "uncoordinated and unplanned growth" that
    the legislature found to "pose a threat to the environment, sustainable economic
    development, and the health, safety, and high quality of life enjoyed by residents of
    this state." RCW 36.70A.010.
    The County argues that placing responsibility for protecting water resources on
    local governments transfers Ecology's statutory responsibility to administer chapter
    90.44 RCW to the counties. They are wrong under our description of the proper
    division of authority set forth in Kittitas County: "Ecology is responsible for
    appropriation of groundwater by permit ... , the County is responsible for land use
    decisions that affect groundwater 
    resources." 172 Wash. 2d at 180
    .
    Rather than address the language of the GMA, the County asserts that the
    proper inquiry is whether its comprehensive plan is consistent with Ecology's
    regulations designed to protect water and to ensure that water is legally available. For
    support, the County cites numerous provisions describing the GMA as a cooperative
    endeavor between local governments and state agencies with subject matter
    expertise. See, e.g., RCW 90.54.130 (Ecology may provide local governments and
    state agencies with advisory recommendations to assist the counties in protecting
    water resources).
    Notwithstanding the cooperative approach envisioned by the Act, the GMA
    clearly places sole responsibility for land use decisions affecting groundwater
    resources on local governments. Counties are authorized by statute to grant or deny
    building permits, and the legislature has imposed on the counties the responsibility of
    protecting the availability of water, RCW 36.70A.020(1 0), protecting groundwater
    27
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    resources, RCW 36.70A.070(5)(c)(iv), and ensuring an adequate supply of water
    when it approves a building permit. RCW 19.27.097(1 ); RCW 58.17.11 0.
    In contrast, the legislature recognized that Ecology plays an advisory role to
    counties making land use decisions by providing counties with model regulations and
    assistance. RCW 90.54.130; Kittitas 
    County, 172 Wash. 2d at 180
    . In counties required
    to plan pursuant to the GMA, the legislature recognized that Ecology's permitting
    authority could provide evidence of the availability of water (RCW 19.27.097(1 )). And
    in counties that are not required to plan pursuant to the GMA, the legislature gave
    Ecology authority to coordinate with the Department of Health to determine whether
    an applicant must demonstrate the legal availability of water (RCW 19.27.097(2)). In
    addition, Ecology may provide local governments with advisory recommendations to
    assist those governments in protecting water resources. RCW 90.54.130. The
    legislature further recognized Ecology's administrative role in the GMA, stating that a
    county's land use regulations "should be consistent with ... instream flow rules"
    promulgated by Ecology. WAC 365-196-825(3). Notably, none of these statutes
    authorize local governments to delegate their GMA planning responsibilities to
    Ecology.
    Further, interpreting "assistance" to merely require counties to conform to
    existing regulations would render the GMA's water protection requirements
    superfluous. The legislature adopted the GMA in 1991, 20 years after the WRA and
    six years after Ecology promulgated the Nooksack Rule. As observed throughout this
    opinion, the Act places numerous requirements on local governments to protect the
    availability of water. See RCW 36.70A.070(1), (5)(c)(iv); see also RCW 19.27.097;
    28
    Whatcom County, Hirst (Eric)    v. W. Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    RCW 58.17.110. "Statutes must be interpreted and construed so that all the language
    is given effect, with no portion rendered meaningless of superfluous." G-P Gypsum
    Corp.   v. Dep't of Revenue, 
    169 Wash. 2d 304
    , 309, 
    237 P.3d 256
    (2010); see also
    Tunstall   v. Bergeson, 
    141 Wash. 2d 201
    , 211, 
    5 P.3d 691
    (2000) ('To resolve apparent
    conflicts between statutes, courts generally give preference to the more specific and
    more recently enacted statute."). The GMA provisions would be superfluous if the
    County's only obligation was to defer to Ecology's water regulations.
    The County specifically contrasts its cooperative efforts with the actions at issue
    in Kittitas County, where we affirmed the Board's finding of noncompliance in part
    because the policies in that case effectively evaded compliance with Ecology's water
    permitting requirements. See Kittitas 
    County, 172 Wash. 2d at 180
    -81. Asserting that its
    plan is entirely consistent with Ecology's regulations, the County urges us to find that
    its comprehensive plan is GMA compliant.
    This argument is incongruous: the fact that the County's provisions are wholly
    consistent with Ecology's regulations does not, by itself, render them consistent with
    the GMA's requirements. We require counties "to plan for land use in a manner that is
    consistent with the laws regarding protection of water resources and establishing a
    permitting process." /d. at 180; see also WAC 365-196-825(3). However, nothing in
    Kittitas County or in the GMA suggests that consistency with Ecology's regulations is
    sufficient for GMA compliance. 
    See 172 Wash. 2d at 180-81
    . This argument rests on a
    logical fallacy. The GMA requires counties to have a comprehensive plan that protects
    surface and groundwater resources, and it requires applicants seeking approval for
    building permits or subdivision developments to provide that county with evidence of
    29
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    an adequate water supplies as well as potable water supplies, among other
    provisions. See RCW 36.70A.070(5)(C)(iv); RCW 19.27 .097(1 ); RCW 58.17.11 0. The
    Board correctly found that the County's plan does not satisfy these requirements.
    It is true that the GMA places significant responsibility on local growth
    management planners and administrators to work with existing laws and regulations
    "toward producing a single harmonious body of law." WAC 365-196-700(2). However,
    the scope of this responsibility does not support a dilution of the Act's purpose.
    Recognizing the challenge this presents to local governments, the legislature directed
    the Department of Commerce to provide technical assistance to local governments.
    See RCW 36.70A.190. Additionally, Ecology was authorized to provide land use
    management advisory recommendations to state agencies and local governments in
    furtherance of protecting this state's water resources. RCW 90.54.130.
    This cooperative approach is designed to give local governments the tools they
    need to make informed decisions toward achieving harmony under the GMA.
    However, the cooperative approach does not allow counties to disregard evidence of
    minimum flow impairments in reliance on an outdated regulation. The GMA is a
    mandate to government at all levels-municipalities, counties, regional authorities,
    special purpose districts, and state agencies-to engage in coordinated planning and
    cooperative implementation. WAC 365-196-700(5). In allocating responsibilities to
    achieve these policy goals, the legislature placed the responsibility to plan for the
    protection of water resources on county governments. See Kittitas 
    County, 172 Wash. 2d at 179
    .
    30
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    E. The County plan is inconsistent with our minimum flows jurisprudence
    In addition to the deficiencies in the County's comprehensive plan under the
    GMA, the Board properly ruled that the plan is inconsistent with our decisions
    protecting closed basins and minimum flows from groundwater appropriations. There
    is no question that a permit-exempt well may not infringe on an earlier-established
    right to water under the doctrine of prior appropriation. See Campbell & 
    Gwinn, 146 Wash. 2d at 16
    . We reiterated this point in Swinomish Indian Tribal Community,
    recognizing that an appropriator's right to use water from a permit-exempt well is
    subject to rights with priority in time, including minimum 
    flows. 178 Wash. 2d at 598
    . The
    GMA protects these senior water rights by requiring local governments to determine
    that applicants for building permits or subdivision developments have demonstrated
    that an adequate water supply is legally available before authorizing approval. RCW
    19.27.097(1); RCW 58.17.110.
    Here, the Board specifically found that the "water supply provisions referenced
    . do not require the County to make a determination of the legal availability of
    groundwater," with the result that the County's ordinance directly conflicts with the
    standard announced in Postema. FDO at 40. In Postema, we held that a minimum
    flow, once established by Ecology, is an existing water right that may not be impaired
    by subsequent groundwater 
    withdrawals. 142 Wash. 2d at 81
    . "Accordingly, when
    Ecology determines whether to issue a permit for appropriation of public groundwater,
    Ecology 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." /d. at 80-81. "[W]here there is hydraulic continuity and
    31
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    withdrawal of groundwater would impair existing surface water rights, including
    minimum flow rights, then denial [of a permit] is required." /d. at 93.
    Though Postema was specifically decided in the context of Ecology's
    requirements prior to issuing permits, the rule in Washington is that groundwater
    appropriations cannot impede minimum flows. 11 Swinomish Indian Tribal 
    Cmty., 178 Wash. 2d at 598
    . It would be incongruous to limit Postema to the holding that Ecology
    must consider the effect of groundwater appropriations on minimum flows when
    issuing permits but that the County does not need to consider these same impacts
    when issuing building permits. The County emphasizes that Ecology expressly does
    not engage in the usual review of a permit application when considering permit-
    exempt wells and exempt-use applications are not reviewed for impairment of existing
    rights. This argument misses the mark-the GMA explicitly assigns that task to local
    governments. See RCW 19.29.097(1); RCW 58.17.110.
    A recent decision from Division One of the Court of Appeals in Fox v. Skagit
    County, 
    193 Wash. App. 254
    , _       P.3d _   (2016), petition for review filed, No. 93203-4
    (Wash. June 7, 2016), 12 lends further support to the conclusion that counties must
    11 In Postema, we considered Ecology's denial of applications for groundwater appropriation
    permits on the basis that groundwater sources are in hydrological continuity with surface
    water sources and further appropriations were foreclosed under RCW 
    90.03.290. 142 Wash. 2d at 77-78
    . In analyzing whether Ecology properly denied permits under RCW 90.03.290, we
    considered the statutory requirements placed on Ecology to consider the interrelationship
    between surface waters and groundwater in issuing permits and asserted that Ecology "must
    determine whether surface water rights would be impaired or affected by groundwater
    withdrawals." /d. at 80-81. This was particularly relevant because RCW 90.03.290, which
    authorizes Ecology to issue permits for water appropriation, "does not ... differentiate
    between the impairment of existing rights based on whether the impairment is de minimis or
    significant." /d. at 90.
    12 The decision of the Court of Appeals in Fox was issued after oral argument in the present
    32
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    consider minimum flows when issuing building permits, even for developments relying
    on permit-exempt wells. The case concerned the denial of a building permit where the
    only source of water for the proposed development was from a permit-exempt well in
    hydraulic continuity with a river that was subject to an instream flow rule, and that
    regularly falls below its minimum flow requirements. /d. at 260. The Court of Appeals
    rejected the argument that a permit-exempt well would satisfy on its own the
    "adequate water supply" requirement for a building permit under RCW 19.27.097. /d.
    at 269-70. Because the right to use a permit-exempt well is subject to the prior
    appropriation doctrine, the court held that a determination of water availability for
    purposes of issuing a building permit requires that the county consider whether the
    development would impair senior water rights, including rights established by an
    instream flow rule. /d. The opinion in Fox is consistent with our prior decisions in
    Kittitas County, Swinomish Indian Tribal Community, and Postema, and with our
    decision today.
    By deferring to Ecology's Nooksack Rule, the County authorizes building
    permits on a presumption of water availability in lieu of the GMA's requirement of
    case had occurred. Petitioners submitted this additional authority to the Court for
    consideration. Appellant's Statement of Additional Authority at 1. In their statement, the
    petitioners quoted several passages from the opinion, prefacing each quote with a short
    statement about the context or meaning of the passage. Respondent County objected to
    petitioners' statement, claiming that it contained impermissible argument in violation of RAP
    10.8. Objection to Appellants' Statement of Additional Authority at 1. Respondent asked this
    court to either reject the statement or, in the alternative, strike all argument from the
    statement. /d. at 2. Under RAP 10.8, a party should identify the issue for which the additional
    authority is offered but the statement "should not contain argument." We agree with the
    respondent that the petitioners' commentary on the quoted passages crosses the line
    between permissible identification and impermissible argument. We grant the respondent's
    motion to strike this language from petitioners' statement, but we decline to reject the
    statement in full.
    33
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    "evidence of adequate water supply." As authorized by RCW 90.54.020(3), Ecology's
    Nooksack Rule established instream flows as "necessary to provide for preservation
    of wildlife, fish, scenic, aesthetic and other environmental values" at WAC 173-501-
    030(1) to (3); these regulations expressly provide that only Whatcom Creek is closed
    to permit-exempt uses. See WAC 173-501-040(1), -070(2). However, the Nooksack
    Rule does not provide that water is legally available for permit-exempt uses in all other
    streams in WRIA 1. See WAC 173-501-040(1), -070(2); see generally ch. 173-501
    WAC.
    As the Board correctly states, each water use appropriation requires a fact-
    specific determination. RCW 19.29.097(1 ); RCW 58.17.11 0. Because the County's
    plan does not require applicants to present evidence of water availability, the unasked
    question in the County is whether there is water that is legally available and that can
    be appropriated in certain areas of rural Whatcom County without conflicting with the
    applicable instream flows. Instead of evidence, the County presumes that water is
    available for all permit-exempt wells unless Ecology has explicitly closed a basin to all
    groundwater appropriations, specifically including permit-exempt appropriations. 13
    The Board correctly found that this approach has an adverse impact on minimum
    flows, that it does not comply with the GMA, and that it is incompatible with our
    13 Counties may not rely on Ecology's inaction in failing to close a basin as a determination
    that water is presumptively available for appropriation. Such inaction fails to provide any
    assurance that a new permit-exempt well will not infringe on senior water rights, and thus fails
    to satisfy the obligation the GMA places on counties to ensure that water is legally available
    before issuing a building permit. See RCW 19.29.097(1); RCW 58.17.110. However, if and
    when Ecology makes a determination to close a basin to all future appropriations, including
    permit-exempt appropriations, this positive action by Ecology amounts to a recognition that
    water is not available for any use, and may form a reasonable basis for a county to find that
    water is not legally available for further appropriation.

    Whatcom County, Hirst (Eric) v: W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    decisions that consistently protect instream flows from impairment by groundwater
    withdrawals.
    Ill.      The Board Properly Ruled That the County's Rural Element Fails To Comply
    with the Requirement To Protect Water Quality
    We reverse the Court of Appeals in part and hold that the Board's ruling that
    the County's rural element does not comply with the requirement to protect water
    quality is based on a proper interpretation and application of the law. The County
    argues-and the Court of Appeals agreed-that the Board's reliance on preexisting
    water quality problems in Whatcom County improperly imposed a duty on the County
    to "enhance" water quality rather than to merely "protect" water quality. The County is
    correct that it does not have a duty to enhance water quality; however, the Board's
    ruling does not require counties to enhance water quality and the decision is
    supported by substantial evidence. 14
    A. Comprehensive plans are not required to include provisions that enhance
    water quality
    The GMA imposes several requirements and goals on a local government's
    planning. Comprehensive plans "shall provide for protection of the quality ... of
    groundwater used for public water supplies." RCW 36.70A.070(1) (emphasis added).
    It is a goal of the GMA to "[p]rotect the environment and enhance the state's high
    quality of life, including air and water quality." RCW 36.70A.020(10) (emphasis
    added).
    14 During oral argument, the County conceded that it had notice of two documents by the
    second hearing before the Board and that the documents were now properly a part of the
    record. See Wash. Supreme Court oral 
    argument, supra, at 52
    min., 45 sec. to 57 min., 17
    sec. Based on this concession and our reasoning at Section III.B, infra, we do not address
    this procedural argument further.
    35
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    Hirst urges us to hold that counties must "enhance" water quality, relying on the
    County's related argument that local governments must adhere to the "planning goals"
    and "[g]eneral declaration of fundamentals" found in RCW 34.70A.020 and RCW
    90.54.020, respectively, such that a county's comprehensive plan must both "protect"
    and "enhance" water quality. However, nothing in the language of either statute or in
    our prior interpretations of the GMA goals support this interpretation.
    Subsection .020 of the GMA, chapter 36.70A RCW, provides 13 planning goals
    to "guide the development and adoption of comprehensive plans and development
    regulations of those counties and cities that are required or choose to plan under
    [subsection .040]." The goals "are not listed in order of priority and shall be used
    exclusively for the purpose of guiding the development of comprehensive plans and
    development regulations." RCW 36.70A.020. Additionally, "the GMA 'explicitly denies
    any order of priority among the thirteen goals' and it is evident that 'some of them are
    mutually competitive."' Quadrant 
    Corp., 154 Wash. 2d at 246
    (quoting 
    Settle, supra
    , at
    11 ). Nothing in this plain language suggests that GMA goals impose substantive
    requirements on local governments.
    Indeed, we rejected a similar argument in Swinomish Indian Tribal Community
    when we held that the term "protect" does not impose a duty on counties to "enhance"
    water quality under RCW 36.70A.172(1 
    ). 161 Wash. 2d at 428
    . There, we considered the
    Swinomish Tribe's argument that the requirement to "protect" critical areas under the
    GMA requires measures to "enhance" because "where an area is already in a
    degraded condition, it is not being protected unless that condition is improved or
    enhanced." /d. at 427. In rejecting that argument, we recognized that the term "protect"
    36
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    may encompass an option of enhancement but that the term itself does not require
    enhancement. /d. at 429. We also considered the legislature's deliberate use of the
    terms "protect" and "enhance" throughout the GMA, finding that "[i]n several sections
    of the GMA, the legislature allows enhancement of natural conditions under the GMA
    without requiring enhancement." /d. We have acknowledged that RCW 36.70A.020
    lists the enhancement of water quality as a goal of the GMA, see 
    id., but have
    never
    held that local governments are bound by these goals in addition to the enumerated
    requirements of the Act. See Quadrant 
    Corp., 154 Wash. 2d at 246
    . We adhere to that
    holding here-the GMA does not require counties to "enhance" water quality.
    Hirst's argument under the WRA fares no better than their argument under the
    GMA. Subsection .020 of the WRA, entitled "General declaration of fundamentals for
    utilization and management of waters of the state," reads in relevant part:
    Utilization and management of the waters of the state shall be guided by
    the following general declaration of fundamentals:
    (3) The quality of the natural environment shall be protected and,
    where possible, enhanced as follows:
    (b) Waters of the state shall be of high quality. Regardless of the
    quality of the waters of the state, all wastes and other materials and
    substances proposed for entry into said waters shall.be provided with all
    known, available, and reasonable methods of treatment prior to entry.
    Notwithstanding that standards of quality established for the waters of
    the state would not be violated, wastes and other materials and
    substances shall not be allowed to enter such waters which will reduce
    the existing quality thereof, except in those situations where it is clear
    that overriding considerations of the public interest will be served ....
    37
    Whatcom County, Hirst (Eric)    v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    (5) Adequate and safe supplies of water shall be preserved and
    protected in potable condition to satisfy human domestic needs.
    RCW 90.54.020. The plain language of this section requires the quality of the natural
    environment to be "protected." Waters are protected in part when "wastes and other
    materials and substances" are not allowed to enter the waters when those materials
    will reduce the existing quality of the water. RCW 90.54.020(3)(b ). The statute further
    provides that "[a]dequate and safe supplies of water shall be preserved." RCW
    90.54.020(5). The language in the WRA does not suggest that water quality must be
    "enhanced," and it does not supersede language from the GMA requiring water to be
    "protected." These goals, while admirable, simply do not impose a duty on counties to
    enhance water quality.
    B. The Board's conclusion about water quality is not based on a duty to enhance
    water quality
    The Board did not rule that the County had an obligation to enhance water
    quality. Its ruling that the County's policies relating to water quality do not satisfy the
    requirements of the GMA identifies two specific problems. We address these concerns
    in turn.
    First, the Board concluded that the County policies 2DD.2.C.1, -2.C.3, -2.C.4,
    and -2.C.8 either do not apply throughout the County's rural area or apply only to parts
    of the rural area. See FDO at 36, 39, 43. The Board further found that "no measures
    exist to limit development to protect water resources in the remaining portions of the
    County's Rural Area." /d. at 38 (emphasis omitted); see also 
    id. at 39
    ("[T]he County's
    Stormwater Manual does not provide measures to protect groundwater throughout the
    County's Rural Area."). Given these deficiencies, the Board concluded that
    38
    Whatcom County, Hirst (Eric) v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    the County is left without Rural Element Measures to protect rural
    character by ensuring land use and development patterns are consistent
    with protection of surface water and groundwater resources throughout
    its Rural Area. This is especially critical given the water supply limitations
    and water quality impairment documented in this case ....
    /d. at 43. The conclusion that these policies do not protect water quality is not based
    on a duty to enhance water quality.
    Second, the Board found that policy 2DD-2.C.2 "is not a measure limiting
    development to protect water resources as required in RCW 36.70A.070(5)( c)(iv)." /d.
    at 37-38. This policy is implemented through chapter 24.05 WCC, which allows private
    homeowners in rural areas to inspect their own septic systems rather than requiring
    professional inspections. The Board noted significant disparity in reported failure rates
    and compliance rates between homeowners who self-inspect versus professional
    inspections, as well as studies showing water quality contamination from faulty septic
    systems. /d. at 37.
    In essence, the Board ruled that the County's current inspection system policies
    were flawed and that continuing to rely on this flawed system would not protect water
    quality in the future. See 
    id. at 36-39.
    This also does not impose a duty on counties to
    enhance water quality. We therefore reverse the Court of Appeals and hold that the
    Board applied the proper legal standard and analysis in concluding that the County's
    rural element policy does not comply with the GMA.
    The County also asserts that the Board's findings are not supported by
    substantial evidence. We note that the Board cited a "proliferation of evidence in the
    record of continued water quality degradation resulting from land use and
    development activities," 
    id. at 35,
    including scientific reports in Ecology's 2010 State

    Planning for Salmon, Stee/head and Trout; and the Puget Sound Partnership's
    2012/2013 Action Agenda for Puget Sound. KATIE KNIGHT, WASH. DEP'T OF FISH &
    WILDLIFE, LAND USE PLANNING FOR SALMON, STEELHEAD, AND TROUT: A LAND USE

    2009 REPORT); PUGET SOUND P'SHIP, THE 2012/2013 ACTION AGENDA FOR PUGET
    SOUND (2012). These reports conclude that water resource degradation in the County
    can be attributed to land use and land development practices. FDO at 32-33 (citing
    WDFW 2009 
    REPORT, supra, at 77
    (2009)). These reports also determined that
    "'stormwater runoff is the leading contributor to water quality pollution of urban
    waterways in western Washington State."' /d. at 32 (quoting WDFW 2009 
    REPORT, supra, at 39-40
    ).
    The County's arguments dismissing this evidence as merely "generalized
    evidence of water quality problems" miss the point: as the Board properly observed,
    counties must include protective measures in their comprehensive plan. /d. at 35
    (citing Kittitas 
    County, 172 Wash. 2d at 164
    ). The Board's conclusion that the County
    plan does not have the necessary measures to comply with this requirement is all that
    is needed to establish that the County's comprehensive plan does not satisfy the
    GMA. The evidence cited by the Board is not essential to this ruling; it is instead
    intended to underscore the importance of implementing effective protective measures
    in rural Whatcom County. Therefore, we reverse the Court of Appeals' holding that the
    Board's decision improperly imposed a duty on the County to "enhance" water quality
    40
    Whatcom County, Hirst (Eric)   v. W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3
    rather than to merely "protect" water quality and affirm the Board's ruling that the
    County's rural element fails to comply with the requirement to protect water quality.
    IV.    The Board Has Discretion To Declare a Comprehensive Plan Invalid
    Finally, Hirst cross appeals the Board's decision declining to declare the
    County's comprehensive plan invalid. Hirst argues that the Board erroneously
    interpreted and applied the GMA because it applied an incorrect legal standard. We
    hold that the Board did not abuse its discretion in declining to make a determination
    of invalidity.
    The GMA provides statutory remedies for plans or regulations that the Board
    determines violate the GMA. As we have previously observed when interpreting these
    provisions, the GMA provides the Board with "two options: (1) it may enter a finding of
    noncompliance or (2) it may enter a finding of invalidity." Town of Woodway v.
    Snohomish County, 
    180 Wash. 2d 165
    , 174, 
    322 P.3d 1219
    (2014) (citing RCW
    36. 70A.300(3)(b ), .302). We review the Board's exercise of these options for abuse of
    discretion. See 
    id. RCW 36.70A.302(1)
    provides the legal standard under which the Board
    determines whether to make a finding of invalidity:
    (1) The board may determine that part or all of a comprehensive
    plan or development regulations are invalid if the board:
    (a) Makes a finding of noncompliance and issues an order of
    remand under RCW 36.70A.300;
    (b) Includes in the final order a determination, supported by
    findings of fact and conclusions of law, that the continued validity of part
    or parts of the plan or regulation would substantially interfere with the
    fulfillment of the goals of this chapter; and
    (c) Specifies in the final order the particular part or parts of the
    plan or regulation that are determined to be invalid, and the reasons for
    their invalidity.

    Whatcom County, Hirst (Eric) v: W Wash. Growth Mgmt. Hr'gs Bd., No. 91475-3

    existence of an option that is a matter of discretion. Nat'! Elec. Contractors Ass'n v:

    858 P.2d 245
    (1993));
    see also WAC 365-196-21 0(20).
    In denying Hirst's request for an order of invalidity, the Board stated:
    This Board has previously held that it will declare invalid only the
    most egregious noncompliant provisions which threaten the local
    government's future ability to achieve compliance with the Act. Although
    the Board finds areas of noncompliance with the GMA, Petitioners have
    not met the standard for a declaration of invalidity.
    FDO at 50 (footnote omitted).
    Hirst argues, correctly, that the GMA standard for a determination of invalidity
    is not "the most egregious noncompliant provisions which threaten the local
    government's future ability to achieve compliance with the Act." While this is a correct
    statement of the law, it is irrelevant to determining whether the Board properly
    exercised its discretion by requiring a heightened showing before it elects to invalidate
    a noncompliant provision. As the quoted language shows, the Board is asserting its
    own standards for invalidating provisions. Hirst's argument fails to acknowledge that
    the plain language of subsection .302(1) articulates the threshold requirements for a
    board to make a determination of invalidity; a board may not make a determination of
    invalidity if those requirements are not satisfied, but it is not required to make a finding
    of invalidity if they are. Cf. Spokane County v: E. Wash. Growth Mgmt. Hr'gs Bd., 
    176 Wash. App. 555
    , 578,

    the statutory requirements and was based on due consideration of the facts), review
    denied, 
    179 Wash. 2d 1015
    (2014). Therefore, we affirm the Court of Appeals on this
    issue and hold that the Board did not abuse its discretion in declining to make a finding
    of invalidity.
    CONCLUSION
    We reverse the Court of Appeals and hold that the County's comprehensive
    plan does not satisfy the GMA requirements to protect water availability or water
    quality. However, we affirm the Court of Appeals' holding that the Board did not abuse
    its discretion in declining to make a finding of invalidity. We therefore reverse the Court
    of Appeals in part and remand to the Board for further proceedings consistent with this
    opinion.

    MADSEN, C.J. (concurring)-! agree with the majority that the Growth
    Management Act (GMA), chapter 36. 70A RCW, places a burden on counties to assure
    the factual and legal availability of water before issuing building permits. And Whatcom
    County (County) failed to meet this burden by simply relying on the Department of
    Ecology's "Nooksack Rule" 1 rather than actually making a finding that water was
    available. I write separately to emphasize the duty of the State, tribes, and local
    governments to work together to ensure there is available water before issuing building
    permits, rather than letting their burden fall onto individual permit applicants.
    Discussion
    The majority holds that the County failed to meet its duty under the GMA to
    ensure water was factually and legally available before issuing building permits.
    Majority at 2, 13. I agree with this holding. The GMA places a duty on counties to
    ensure that water is both factually and legally available before they issue building
    permits. RCW 19.27.097(1); RCW 58.17.110(2); see majority at 18-20. This court has

    (2011 ); see majority at 20-21.
    Here, the County failed to ascertain whether there was available water before
    issuing building permits. Rather, the County shifted its statutory duty under the GMA to
    the Department of Ecology by adopting Ecology's presumptive Nooksack Rule. Where,
    as here, Ecology has not actually determined whether water is available, the County is not
    entitled simply to rely on Ecology's rule. 2 As the majority holds, the County has an
    independent duty under the GMA to ensure water is both factually and legally available
    before issuing building permits.
    I write separately to address the dissent's concern that the majority is shifting the
    burden of showing water availability onto individual permit applicants. Dissent at 1, 16.
    Like the dissent, I fear the majority could be read to say that if the County cannot rely on
    Ecology's rule, then it can shift its burden onto permit applicants. But that is not so.
    Rather, the State and local governments have independent statutory duties to ensure water
    availability, and they must work together to protect water resources and ensure water
    availability as part of their comprehensive planning process. 3
    2
    By adopting the Nooksack Ru1e, the County presumes there is an adequate supply to provide
    water for a permit-exempt well unless Ecology has expressly closed that area to permit-exempt
    appropriations. Majority at 2. As the majority notes, this means the County's position is that
    "water is presumptively available-i.e., that 'not unavailable' is synonymous with 'available."'

    id. at 21-22.

    Ecology is, of course, not a party to this case, so this court cannot direct what it must do to
    assist the Cotmty in the development of a comprehensive plan and zoning code that meets the
    County's obligations under the GMA. But this case presents an opportunity to highlight the
    2
    91475-3
    Madsen, C.J., concurring
    The State and the counties each have an independent statutory duty to ensure
    water availability. For example, before issuing a groundwater permit, Ecology must
    investigate and 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." Dep't ofEcology v. Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    , 8, 
    43 P.3d 4
    (2002) (citing RCW 90.03.290). Under the GMA, a county's comprehensive plan, RCW
    36.70A.040, must include a land use element that provides for the "protection of the
    quality and quantity of groundwater used for public water supplies." RCW
    36.70A.070(1). And before issuing a building permit, a county must determine that there
    are potable water supplies. RCW 58.17.110(2)(a). Thus, both the State and the counties
    have an independent duty to ensure water availability prior to issuing permits.
    Although each has an independent statutory duty, the legislature envisioned
    cooperation between the State and local governments when it enacted the Water
    Resources Act of 1971 (WRA), chapter 90.54 RCW, and, later, the GMA. The
    legislature included language highlighting this cooperative approach throughout the
    statutes:
    To ensure that available water supplies are managed to best meet both
    instream and offstream needs, a comprehensive planning process is
    essential .... Through a comprehensive planning process that includes the
    state, Indian tribes, local governments, and interested parties, it is possible
    to make better use of available water supplies and achieve better
    management of water resources. Through comprehensive planning,

    Madsen, C.J., concurring
    conflicts among water users and interests can be reduced or resolved. It is
    in the best interests of the state that comprehensive water resource planning
    be given a high priority.
    RCW 90.54.010(1)(b) (emphasis added); RCW 36.70A.103 (state agencies shall comply

    governments on a proposed comprehensive plan); RCW 19.27.097(2) (county and state
    may mutually determine to which areas the building permit requirements do not apply);
    see also WAC 365-196-700(5) ("The [WRA] is a mandate to government at all levels to
    engage in coordinated planning and cooperative implementation.").
    This court has recognized the cooperative spirit that the legislature envisioned
    when enacting these statutes. In Kittitas County, while reaffirming the county's
    responsibility in land use decisions, we emphasized, "[W]e do not intend to minimize the
    role of Ecology. Ecology maintains its role, as provided by statute, and ought to assist
    counties in their land use planning to adequately protect water 
    resources." 172 Wash. 2d at 180
    (emphasis added). The majority too recognizes the cooperative approach that the
    GMA envisions. Majority at 27. But the majority focuses on how the County cannot use
    the cooperative approach to "disregard evidence of minimum flow impairments in
    reliance on an outdated regulation." !d. at 30. While I agree, I think it should be made
    clear that the statutes do not expect the burden to fall on individual applicants where the
    County has failed to meet its initial burden of determining water availability through its
    comprehensive planning and development regulations.
    4
    91475-3
    Madsen, C.J., concurring
    When the counties and Ecology combine their planning and water resources
    authority, the technical resources and planning solutions offer a wide range of tools to
    ensure water availability. For example, a county can make its densities consistent with
    water availability, provide water mitigation, or ensure there are limited impervious
    4
    surfaces so that more water goes into streams. Although the legislature has placed a
    burden on individual applicants to provide evidence of water, RCW 19.27.097(1), there
    are steps that the State and the counties must take under their statutory duties to protect
    water resources, ensure water availability, and engage in a comprehensive planning
    process. The burden on permit applicants under RCW 19.27.097(1) assumes that the
    State and the counties have already complied with their statutory duties to ensure the
    availability of water. Thus, the burden to provide evidence of water falls on individual
    applicants only where the State and the counties have first fulfilled their statutory duties
    of ensuring that water is available.
    The State and the counties cannot meet their respective duties to protect this
    State's dwindling water resources by relying on one another's rules or shifting their
    burdens to others. As stewards of our valuable water resources, the State and the
    counties must work together to develop comprehensive plans to address water usage in

    STEPHENS, J. (dissenting)-The majority's decision hinges on an
    interpretation of RCW 19.27.097 that is unsupported by the plain language of the
    statute, precedent, or common sense. It assumes this provision of the building code
    requires Whatcom County to determine water right priorities before it may grant a
    building permit that relies on a permit-exempt well. It also assumes this provision
    prohibits the county from relying on the Department of Ecology's determination of
    whether water is available for withdrawal in a particular basin. The effect of the
    majority's holding is to require individual building permit applicants to commission
    a hydrogeological study to show that their very small withdrawal does not impair
    senior water rights, and then have the local building department evaluate the
    adequacy of that scientific data. The practical result of this holding is to stop
    counties from granting building permits that rely on permit-exempt wells. Not only
    Whatcom County, Hirst (Eric), et al. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    is this contrary to the clear legislative purpose ofRCW 19.27.097, it potentially puts
    counties at odds with the Department of Ecology and imposes impossible burdens
    on landowners. I respectfully dissent.
    L       RCW 19.27.097 Does Not Require Building Permit Applicants To Provide
    Evidence of the Legal Availability of Water
    The majority holds that to satisfy the Growth Management Act (GMA),
    chapter 36.70A RCW, the county cannot rely on the Department of Ecology's water
    availability determinations, but instead must require building permit applicants
    relying on permit-exempt wells to provide the county with evidence that water is
    both factually and legally available. See majority at 19-20. The majority's holding
    relies on a faulty interpretation ofRCW 19.27 .097. That statute provides in relevant
    part,
    (1) Each applicant for a building permit of a building necessitating potable
    water shall provide evidence of an adequate water supply for the intended
    use of the building. Evidence may be in the form of a water right permit
    from the department of ecology, a letter from an approved water purveyor
    stating the ability to provide water, or another form sufficient to verify the
    existence of an adequate water supply. In addition to other authorities, the
    county or city may impose conditions on building permits requiring
    connection to an existing public water system where the existing system is
    willing and able to provide safe and reliable potable water to the applicant
    with reasonable economy and efficiency. An application for a water right
    shall not be sufficient proof of an adequate water supply.
    (2) Within counties not required or not choosing to plan pursuant to
    RCW 36.70A.040, the county and the state may mutually determine those
    areas in the county in which the requirements of subsection (1) of this section
    shall not apply. The departments of health and ecology shall coordinate on
    the implementation of this section. Should the county and the state fail to
    -2-

    (Stephens, J. Dissenting)
    mutually determine those areas to be designated pursuant to this subsection,
    the county may petition the department of enterprise services to mediate or,
    if necessary, make the determination.
    RCW 19.27.097.
    While part of the GMA, this statute is codified in the building code, chapter
    19.27 RCW. See Kittitas County v. E. Wash. Growth Mgmt. Hr'gs Bd., 
    172 Wash. 2d 144
    , 178-79, 
    256 P.3d 1193
    (2011). It sends a simple message to building permit
    applicants: "show me the water." It does not require counties to modify their growth
    management ordinances to deviate from the Department ofEcology's determination
    of whether water is available for use in a particular basin. Nor does it require
    applicants to undertake the burden of showing that the use of a permit-exempt well
    will not impair senior water rights.
    The plain language of RCW 19.27.097 supports this interpretation.              The
    methods that an applicant may use to show there is an "adequate water supply" speak
    to the actual presence of water, not its legal availability.        RCW 19.27.097(1)
    ("Evidence may be in the form of ... a letter from an approved water purveyor
    stating the ability to provide water."). Furthermore, the statute uses the term
    "adequate" to describe the water supply; it does not use "available." 
    Id. This is
    important, as "[w ]e presume the legislature intends a different meaning when it uses
    different terms." Foster v. Dep't of Ecology, 
    184 Wash. 2d 465
    , 473,

    -3-
    Whatcom County, Hirst (Eric), et al. v. W Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    (20 15). In the water code, where the legislature intends an investigation of both
    factual and legal availability of water, it uses the term "available." See RCW
    90.03.290(1) (providing that under the water code's appropriation procedure, it is
    the duty of the Department of Ecology to "determine what water, if any, is available
    for appropriation" (emphasis added)), .290(3) ("if [the department] 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 . . . . But where there is no
    unappropriated water in the proposed source of supply, or where the proposed use
    conflicts with existing rights," the department shall reject the application (emphasis
    added)). In GMA regulations, the term "adequate" refers to actual water supply, not
    legal availability. See WAC 365-196-210(3) (Department of Commerce GMA
    regulations defining "adequate public facilities" as "facilities which have the
    capacity to serve development without decreasing levels of service below locally
    established minimums"), -41 0(1 )(d) ("The housing element must contain at least the
    following features: ... [a]dequate provisions for existing and projected housing
    needs of all economic segments ofthe community.").
    The majority's attempt to tie the GMA's broad policy objectives and planning
    goals to this statute overlooks the fact that RCW 19.27.097 applies to both GMA
    -4-
    Whatcom County, Hirst (Eric), et al. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    and non-GMA counties. The statute speaks directly to an individual applicant's
    burdens, not to the required elements of a county's comprehensive plan. See RCW
    19.27.097(1) ("Each applicant for a building permit of a building necessitating
    potable water shall provide evidence of an adequate water supply for the intended
    use of the building." (emphasis added)). Although under this statute non-GMA
    counties can require building permit applicants to provide evidence of an adequate
    water supply, this is not mandated. In non-GMA counties, applicants may or may
    not have to show evidence of potable water. RCW 19.27.097(2) ("Within counties
    not required or not choosing to plan pursuant to RCW 36.70A.040, the county and
    the state may mutually determine those areas in the county in which the requirements
    of subsection (1) ofthis section shall not apply.").
    The majority's holding, which requires applicants for a building permit in a
    GMA county to prove the legal availability of water, will lead to inconsistent
    protection for senior water rights holders across the state. See 1992 Op. Att'y Gen.
    No. 17, at 7 n.4 ("In areas where RCW 19.27.097(1) does not apply, the local
    building department will not need to determine whether there is an adequate water
    supply before issuing a building permit."). Under the majority's interpretation,
    senior water rights holders in GMA counties can rely on counties to look at
    applicants' evidence and deny building permits when permit-exempt wells would
    -5-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    interfere with senior water rights. However, in non-GMA counties where applicants
    relying on permit-exempt wells do not have to prove water is legally available, senior
    water rights holders bear the burden of determining a permit-exempt well is
    interfering with their rights and initiating a lawsuit to stop the impairment. 1 We
    cannot read the requirements of the building code to create such unequal protection
    for senior water rights holders.
    Noticeably missing from the majority's analysis of RCW 19.27.097 is any
    discussion of the inconsistent protection its interpretation creates. The majority
    brushes off this argument, stating, "While the dissent correctly notes that RCW
    19.27.097 contains separate requirements for GMA and non-GMA counties, this
    does not give this court grounds to ignore the rest ofthe GMA." Majority at 20 n.6.
    This court should not interpret a statute so as to give people in some counties greater
    protection for their water right than others, especially when the result is to foster
    piecemeal decision-making regarding water use. By interpreting RCW 19.27.097 to
    mean "show me the water" and allowing counties to rely on the Department of
    Ecology's determination of whether water is legally available, I do not ignore the
    1 Permit-exempt wells that are regularly, beneficially used, are "entitled to a right
    equal to that established by a permit." RCW 90.44.050. "The authority to adjudicate and

    other provisions of the GMA.      Instead, I harmonize the GMA and the Water
    Resources Act of 1971 (WRA), chapter 90.54 RCW, and its goal of consistent
    decision-making-something the majority fails to do.
    The WRA requires the Department of Ecology, "through the adoption of
    appropriate rules ... 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) (emphasis added). The ordinary
    meaning of "comprehensive" is "covering a matter under consideration completely
    or nearly completely." WEBSTER'S THIRD NEW INTERNATIONAL DICTIONARY 467
    (2002); see Tingey v. Haisch, 
    159 Wash. 2d 652
    , 658, 
    152 P.3d 1020
    (2007) ("When a
    term has a well-accepted, ordinary meaning, a regular dictionary may be consulted
    to ascertain the term's definition.").    The legislature recognized the need for
    comprehensive planning to effectively manage water resources:
    To ensure that available water supplies are managed to best meet both
    instream and offstream needs, a comprehensive planning process is
    essential. . . . Through a comprehensive planning process that
    includes the state, Indian tribes, local governments, and interested
    parties, it is possible to make better use of available water supplies and
    achieve better management of water resources. Through compre-
    hensive planning, conflicts among water users and interests can be
    reduced or resolved.
    RCW 90.54.010(l)(b).
    -7-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    The legislature also recognized that water does not respect human-made
    boundaries.   It found that "[c]omprehensive water resource planning is best
    accomplished through a regional planning process sensitive to the umque
    characteristics and issues of each region." RCW 90.54.010(1)(c). The legislature
    entrusted the Department of Ecology with the task of developing and implementing
    the "comprehensive state water resources program." RCW 90.54.040(1). It also
    instructed local governments, including counties, to "whenever possible, carry out
    powers vested in them in manners which are consistent with the provisions of this
    chapter." RCW 90.54.090. In response to the WRA, the Department of Ecology
    established the Water Resources Management Program, see ch. 173-500 WAC, and
    water resource inventory areas, such as the "Nooksack Rule" at issue in this case,
    see, e.g., ch. 173-501 WAC. See also Postema v. Pollution Control Hr'gs Bd., 
    142 Wash. 2d 68
    , 81, 83, 
    11 P.3d 726
    (2000).
    I would interpret RCW 19.29.097 to align with the WRA. Allowing counties
    to integrate the Department of Ecology's water determinations into their
    comprehensive plans and rely on them when reviewing building permit applications
    promotes the integrated, comprehensive management the legislature envisioned. It
    also promotes consistent water management throughout a basin, recognizing that
    basins cross county lines.
    -8-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    In contrast, the majority's rule clashes with the WRA. The majority's holding
    will lead to county-by-county decisions on water use that directly undermine the
    WRA's mandate for a comprehensive water management plan. Not only that, but
    the majority's approach risks a race-to-the-bottom in water management. Counties,
    lacking both the Department of Ecology's expertise and its statewide perspective,
    are ill equipped to thoroughly vet the information that permit applicants will offer to
    show no impairment. Nor do county building departments have an obligation to
    perform their own research or consult with other potentially affected parties (e.g.,
    tribes or other counties) before deciding whether a small well will negatively impact
    a senior water right. Of course, counties often do have an incentive to approve
    building permits, increasing the local tax base and boosting economic growth
    through new development. Requiring counties to make their own determination of
    whether water is legally available-rather than allowing them to rely on the
    Department of Ecology-undermines the comprehensive water management
    required by the WRA. 2
    2
    If the Department of Ecology determines that water is not legally available for
    permit-exempt withdrawals, it has the authority to close a basin to all future consumptive
    use, including permit-exempt wells. See WAC 173-501-070(2) (closing Whatcom Creek
    "to any further appropriation, including otherwise exempted single domestic use"). Under
    the rule I propose, counties could integrate the Department of Ecology's rules into their
    codes and rely on its closure of a basin to permit-exempt withdrawals to deny a building
    permit. Although the majority does not address this scenario, its holding suggests that
    -9-
    Whatcom County, Hirst (Eric), et al. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    Finally, the majority's interpretation is contradicted by the Department of
    Commerce's GMA development regulations and a formal attorney general opinion.
    The Department of Commerce regulations incorporate RCW 19.27.097's
    requirement that applicants for building permits provide evidence "of an adequate
    water supply for the intended use of the building." WAC 365-196-825(1 ). The
    regulations also state that cities and counties should consult 1992 Attorney General
    Opinion No. 17 (AG Opinion), which interprets RCW 19.27.097's requirements "for
    assistance in determining what substantive standards should be applied." WAC 365-
    196-825(2). Formal attorney general opinions "are generally 'entitled to great
    weight."' Five Corners Family Farmers v. State, 
    173 Wash. 2d 296
    ,308,
    268 P.3d 892
    (20 11) (quoting Seattle Bldg. & Constr. Trades Council v. Apprenticeship &
    Training Council, 
    129 Wash. 2d 787
    , 803, 
    920 P.2d 581
    (1996)).
    The AG Opinion explains that "an 'adequate' water supply is one that is of
    sufficient quality and sufficient quantity to satisfy the demand created by the new
    building." 1992 Op. Att'y Gen. No. 17, at 7. Determining whether there is sufficient
    quantity depends on the source of the water: a public water system or another water
    source. !d. at 9-10. Moreover, this is solely a local determination. !d. ("[L]ocal
    counties could not rely on the Department of Ecology's decision to close a basin, but would
    instead have to engage in an independent analysis to determine if a proposed permit-exempt
    withdrawal would, in fact, affect a senior water right before denying a building permit.
    -10-
    Whatcom County, Hirst (Eric), et al. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    building departments will be able to exercise greater discretion when determining
    whether other water sources provide water of sufficient quality and quantity" than
    they may exercise over public water systems). The AG Opinion explains that "any
    applicant for a building permit who claims that the building's water will come from
    surface or ground waters of the state, other than from a public water system, must
    prove that he has a right to take such water." !d. at 10-11. In order to meet this
    burden, the applicant must either have a permit from the Department of Ecology or
    meet the requirements for a permit-exempt we11. 3 See 
    id. (discussing permitting
    requirements and exception). Nothing in the AG Opinion suggests a building permit
    applicant must hire experts or undertake litigation to demonstrate that a permit-
    exempt well will not impair any senior water right.
    In a footnote, the AG Opinion explains that junior water rights-established
    either by permit or by beneficial use of a permit-exempt well-may at times be
    curtailed to ensure no impairment of senior water rights. See 
    id. at 11
    n.5. The AG
    Opinion states,
    3
    To be eligible to utilize a permit-exempt well, the withdrawal of groundwater must
    be "for stock-watering purposes, or for the watering of a lawn or of a noncommercial
    garden not exceeding one-half acre in area, or for single or group domestic uses in an
    amount not exceeding five thousand gallons a day, or as provided in RCW 90.44.052
    [Whitman County clustered residential developments pilot project], or for an industrial
    purpose in an amount not exceeding five thousand gallons a day." RCW 90.44.050.
    -11-
    Whatcom County, Hirst (Eric), et al. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    Although RCW 19.27.097 states that a water right permit from the
    Department of Ecology may be evidence of an adequate water supply, we
    believe that, because of the first-in-time doctrine, it may not be sufficient
    evidence in cases where water is not actually available for withdrawal. In
    areas experiencing drought severe enough to deprive those holding junior
    water rights of water, for example, a local building department could require
    evidence in addition to the water right that a sufficient quantity of water
    actually would be available for the building to be constructed.
    !d.
    This statement should not be misconstrued to suggest that an applicant must
    prove the legal availability of water before the local building department may grant
    a building permit. It does not impose a mandate on local departments. Rather, this
    passage in the AG Opinion describes a situation in which junior water rights have
    been curtailed, and cautions that mere reliance on a Department of Ecology permit
    may not be sufficient in such situations. But, the curtailment of junior water rights
    occurs only after competing water rights have been resolved in superior court. See
    Rettkowski v. Dep 'tofEcology, 122 Wn.2d219, 225,234, 
    858 P.2d 232
    (1993), aff'd

    128 Wash. 2d 508
    , 
    910 P.2d 462
    (1996). The AG Opinion
    therefore suggests that a local building department could require additional evidence
    of no impairment if there has already been a water rights determination and junior
    rights have been curtailed. This limited situation will not affect the majority of
    building permit applications.

    II.       The Majority Misinterprets Kittitas Countyv. Eastern Washington Growth
    Management Hearings Board and Postema v. Pollution Control Hearings
    Board
    The majority relies on Kittitas County to reach its holding that RCW
    19.27.097 requires applicants to show that water is legally available, and that the
    county, not the Department of Ecology, must make the ultimate determination of
    water availability. See majority at 20 ("Through [RCW 19.27.097(1) and RCW
    58.17.110(2)], the GMA requires counties to assure that water is both factually and
    legally available.      Kittitas 
    County, 172 Wash. 2d at 179-80
    .").            The majority
    misinterprets that decision. In Kittitas County we invalidated Kittitas County's
    subdivision regulations that allowed multiple, separately evaluated subdivision
    applications for properties that are all part ofthe same development. We held such
    regulations "tacitly allow[] subdivision applicants to evade this court's rule in
    Campbell & Gwinn."4 Kittitas 
    County, 172 Wash. 2d at 177
    (citing Department of
    Ecology v. Campbell & Gwinn, LLC, 
    146 Wash. 2d 1
    , 
    43 P.3d 4
    (2002)). We held,
    Without a requirement that multiple subdivision applications of
    commonly owned property be considered together, the County cannot meet
    the statutory requirement that it assure appropriate provisions are made for
    potable water supplies. Instead, nondisclosure of common ownership
    information allows subdivision applicants to submit that appropriate
    4
    In Campbell & Gwinn, we held that "commonly owned developments are not
    .exempt [from water permitting requirements] and therefore must comply with the
    established well permitting process if the total development uses more than 5,000 gallons
    of water per day." Kittitas 
    County, 172 Wash. 2d at 177
    .
    -13-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    provisions are made for potable water through exempt wells that are in fact
    inappropriate under Campbell & Gwinn when considered as part of a
    development, absent a permit. To interpret the County's role under RCW
    58.17.110 to require the County to only assure water is physically
    underground effectively allows the County to condone the evasion of our
    state's water permitting laws.
    !d. at 180.
    The majority interprets this case to hold that the county must evaluate the
    factual and legal availability of water. Majority at 20-21. What Kittitas County in
    fact holds is that county regulations cannot circumvent the requirements for valid
    permits issued by the Department of Ecology; subdivision applicants required to
    obtain water permits must obtain valid permits. In Kittitas County, we assumed the
    validity of permit-exempt wells, without requiring a further showing of no water
    rights 
    impairment. 172 Wash. 2d at 180
    . Thus, our decision in Kittitas County does
    not support the majority's imposition of additional burdens on building permit
    applicants and local jurisdictions.
    The majority also improperly relies on our holding in Postema to conclude
    that "[i]t would be incongruous to limit Postema to the holding that Ecology must
    consider the effect of groundwater appropriations on minimum flows when issuing
    permits but that [Whatcom] County does not need to consider these same impacts
    when issuing building permits." Majority at 32. There are two problems with this
    statement. First, it rests on the same faulty interpretation of RCW 19.27.097(1),
    -14-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. Growth Mgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    discussed above. Second, it is not "incongruous" to limit Postema's holding to the
    facts of that case. By transposing a rule adopted for permitted wells into the permit-
    exempt context, the majority ignores the distinction between these types of
    withdrawals. See majority at 32. This statutory-based distinction is discussed in
    greater detail below.     While Postema requires the Department of Ecology to
    determine if a permitted withdrawal of groundwater would negatively impact
    instream flows, nothing in that decision, or in the GMA, shifts this burden onto
    counties when individuals rely on permit-exempt wells. 5
    III       The Practical Effect of the Majority's Holding Is To Prevent New
    Construction That Relies on Permit-exempt Wells
    The majority's holding amounts to a policy decision that GMA counties
    should not issue building permits that rely on permit-exempt groundwater
    withdrawals. This is not a policy decision we are at liberty to make.
    5
    The majority finds additional support for its position "that counties must consider
    minimmn flows when issuing building permits, even for developments relying on permit-
    exempt wells" in Fox v. Skagit County, 
    193 Wash. App. 254
    , _P.3d_ (2016) (Division
    One), petition for review filed, No. 93203-4 (Wash. June 7, 2016). Majority at 33. A
    petition for review is pending in Fox, and it offers no greater authority than the decision
    below, also from Division One of the Court of Appeals. See 
    id. For the
    reasons explained
    above, I would reject Division One's view that a county must determine whether a permit-
    exempt well would infringe senior water rights before issuing a building permit. See 
    id. at 271.
    -15-
    Whatcom County, Hirst (Eric), eta!. v. W. Wash. GrowthMgmt. Hr'gs Bd., 91475-3
    (Stephens, J. Dissenting)
    Determinations of water availability are complex and costly. We recognized
    in Postema that "[t]he interrelationship [between groundwater withdrawals and
    surface water] can be quite complex and effects are sometimes difficult or
    impossible to measure in the field. Also, pumping groundwater may not have a
    discemable effect on surface water until considerable time has passed, depending
    upon the 
    conditions." 142 Wash. 2d at 75-76
    . 6 The majority fails to acknowledge the
    astronomical task it assigns to individual applicants.        This task is particularly
    difficult to justify in light of the smallness of permit-exempt withdrawals?
    6
    The majority relies on Postema for the proposition that the Department of
    Ecology's understanding the effects of groundwater withdrawals on surface water has
    changed over time. See majority at 10. The majority then states that because in Postema
    we held the Department of Ecology must take these impacts into consideration when
    issuing groundwater withdrawal permits, counties must also take these impacts into
    account when issuing building permits. 
    Id. at 10-11.
    As explained above, Postema does
    not require counties to evaluate the legal availability of water when considering building
    permits relying on permit-exempt wells. Furthermore, just because the Department of
    Ecology's understanding of water has evolved does not mean that counties are required to
    reevaluate the science behind the Department of Ecology's basin rules. If a party wishes
    to challenge a basin rule because of"old" science, the party may do so under Washington's
    Adruinistrative Procedure Act, chapter 34.05 RCW. A challenge to the county's
    comprehensive plan is not the appropriate procedure.
    7
    Domestic use permit-exempt wells may not withdraw more than 5,000 gallons of
    water per day. RCW 90.44.050. That equates to 3.47 gallons per minute (gpm). For
    comparison, for houses constructed under the Department of Housing and Urban
    Development mortgage insurance relying on individual water systems, "[t]he system
    should be capable of delivering a flow of 5 gpm." 24 C.P.R. § 200.926d(f)(2)(i). The
    withdrawals at issue in Postema were 280

    This is not to say that studying the effect of permit-exempt wells is
    unimportant, just that it is unlikely to be undertaken by individuals applying for a
    building permit. In a recent publication, the Department of Ecology explained what
    is needed to assess the cumulative effects of permit-exempt groundwater
    withdrawals. See ANN WESSEL, DEP'T OF ECOLOGY, DRAFT: MITIGATION OPTIONS
    FOR THE IMPACTS OF NEW PERMIT-EXEMPT GROUNDWATER WITHDRAWALS 7-9
    (2015). 8 "To understand how exempt well consumptive water use translates into
    effects on streams at a local scale," one must consider multiple factors, including
    well density, hydrogeologic factors, distribution of wells and well depths within the
    subbasin, timing of withdrawals, difference in indoor and outdoor consumptive
    water use, and tangential hydrologic changes due to landscape changes. 
    Id. at 9.
    "To evaluate the effects of groundwater withdrawals on particular streams, some
    type of groundwater model is typically needed. If only one groundwater withdrawal
    is being analyzed, a simple analytical program may suffice." 
    Id. at 10.
    The cost of
    building these models can be quite high. In a recent Court of Appeals case, it was
    estimated that the cost of the "specific hydrogeological data and models [that] are
    needed for informed decisions about managing and allocating water use and

    Furthermore, to best determine the effect of any groundwater withdrawal, it
    1s necessary to investigate the hydrogeology of all connected surface and
    groundwaters. In a draft report discussing the appropriate technical methods for
    assessing the effects of groundwater withdrawals on surface water, technical experts
    from the Department of Ecology stated that "water-withdrawal proposals are always
    best evaluated in the context of an entire watershed. Therefore, the Committee
    recommends that tools and capacity be developed for basin-scale analysis of water
    resources." DEP'T OF ECOLOGY, DRAFT: REPORT OF THE TECHNICAL ADVISORY

    committee found that "the area of investigation for capture analysis must be large
    enough that 100% of the capture for a well or group of wells can be accounted for;
    this may only extend to the nearest surface water, but more often extends out ... to
    the boundaries of the groundwater basin and, sometimes, beyond into adjoining

    information on a basin's hydrogeology."              ld.   Given the complex nature of

    local departments from granting building permits.
    The majority's holding pushes a massive, and likely insurmountable, burden
    onto individuals applying for a building permit. This was not the legislature's intent
    when it enacted RCW 19.27.097. 10             The exemption for small withdrawals of

    (recounting full legislative history). Relevant here is that at the time the legislature enacted
    RCW 19.27.097, it considered eliminating pennit-exempt wells. The original Engrossed
    Substitute House Bill 2929 included a provision that removed the exemption; required
    those who wanted to constmct a previously permit-exempt well to provide the Department
    of Ecology with 60 days' notice; allowed the Department of Ecology to require those
    wishing to construct a formerly exempt well "to apply for a water right permit if the area
    within which the withdrawal would occur is lmown or believed to have problems related
    to water availability, water quality, interference with existing water rights, or other related
    problems which could be adversely affected by additional withdrawals of ground water";
    and allowed the Department of Ecology to deny the permit "if water is not available, if the
    use is not a beneficial use, if the use would adversely affect existing water rights, if the use
    would threaten water quality or if the use would be inconsistent with a local comprehensive
    plan." ENGROSSED SUBSTITUTE H.B. 2929, at 54-55, 51st Leg., Reg. Sess. (Wash. 1990).
    The senate amended the bill, removing these provisions. S. AMEND. ENGROSSED

    (Stephens, J. Dissenting)
    groundwater has "two evident and interrelated purposes: (1) to save the appropriator
    of a very small withdrawal the trouble and expense of applying for a permit where
    the effect of the withdrawal would be very slight; (2) to save the state the trouble
    and expense of processing applications for small withdrawals with little impact on
    the total water available." 1997 Op. Att'y Gen. No. 6, at 6. Requiring individual
    building permit applicants to show that their small withdrawal of water will not
    impair senior rights undermines both of these goals.
    A far more sensible approach is to recognize that RCW 19.27.097 requires
    applicants to show only that sufficient water is factually adequate to support the
    proposed building, and that it is permissible for the county's regulations to follow
    the Department of Ecology's Nooksack Rule. This holding is consistent with GMA
    regulations and with the WRA. See WAC 365-196-825(3) ("If the department of
    ecology has adopted rules on this subject [adequate potable water], or any part of it,
    local regulations should be consistent with those rules. Such rules may include
    instream flow rules ...."); RCW 90.54.040 (requiring the Department of Ecology
    to develop and implement a comprehensive water resources program). It is also
    consistent with Kittitas County, in which we stated that the Department of Ecology
    Settle & 
    Gavigan, supra, at 886-87
    , the bill that was ultimately signed by the governor did
    not contain these provisions. See LAWS OF 1990, 1st Ex. Sess., ch. 17.

    )).
    I would hold that the county's code is consistent with RCW 19.27.097 and
    properly incorporates the Department of Ecology's Nooksack Rule.           Thus, the
    county complied with GMA requirements to protect water. Because the majority
    holds otherwise, I respectfully dissent.
