Opinion:
Wiggins, J.
¶1 We granted review of this challenge to the Western Washington Growth Management Hearings Board's (Board) decision on the validity of Whatcom Coun ty'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.
¶2 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 "Nook-sack Rule"; 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
¶3 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 Wn.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. Id. at 740.
¶4 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 water and groundwater resources. To accomplish this objective, the ordinance amended the County's comprehensive plan policies 2DD-2.C and -2.D, 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.
¶5 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(B)(3), .160(D)(3), .170(E)(3).
II. Procedural History
¶6 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 water and groundwater resources (policies 2DD-2.C.1 through .9) and sought a declaration of invalidity.
A. Board's discussion of applicable law
¶7 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 Wn.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.' " Id. at 14 (emphasis omitted) (quoting RCW 36.70A.070(5)(c)(iv)).
¶8 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.' " Id. 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.' " Id. (emphasis omitted) (quoting RCW 36.70A.030(15)(d), (g)).
¶9 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.' " Id. (emphasis omitted) (quoting RCW 36.70A.020(10)). 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 L. Settle, Washington's Growth Management Revolution Goes to Court, 23 Seattle U. L. Rev. 5, 8 (1999).
¶10 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 must include measures governing rural development to protect water resources.
FDO at 21.
¶11 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), pro tect groundwater resources, RCW 36.70A.070(5)(c)(iv), and ensure an adequate water supply when they approve a building permit, RCW 19.27.097(1); 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. 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.
B. The Board's findings and conclusions on water quality and availability
¶12 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. Id. 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." Id. at 24. Despite the limited water availability, 1,652 permit-exempt wells have been drilled in otherwise closed basins since 1997 and an additional 637 applications were pending in March 2011. Id. 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.' " Id. (quoting Ex. C-671-D at 49 (1999 Whatcom County Water Resource Plan)).
¶13 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.
Id. 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 quality, the Board denied Hirst's request for a declaration of invalidity and instead remanded the ordinance to the County to take corrective action.
¶14 Both parties appealed separately. The County's appeal, focusing exclusively on its measures to protect groundwater 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 appeal-ability 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 ap peals for direct review, and the County's motion for discretionary review of the original FDO.
¶15 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.
¶16 We granted review and now reverse the Court of Appeals in part.
ANALYSIS
¶17 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.
¶18 Consistent with the Board's determination, Hirst asserts that the GMA requires local governments to determine water availability as part of their land use decisions. Hirst argues 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 instream flows.
¶19 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." WCC 24.11.090(B)(3), .160(D)(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."
¶20 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.
¶21 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.
¶22 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 Wn.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 have any impact on stream flows." Id. 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. Id. at 80-81.
¶23 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 Wn.2d 571, 598, 311 P.3d 6 (2013); Foster v. Dep't of Ecology, 184 Wn.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
¶24 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 Wn.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 Wn.2d at 156 (citing Lewis County v. W. Wash. Growth Mgmt. Hr'gs Bd., 157 Wn.2d 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 Wn.2d at 553.
¶25 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 Wn.2d at 552 (quoting Dep't of Ecology v. Pub. Util. Dist. No. 1 of Jefferson County, 121 Wn.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. Id. at 553.
¶26 We review questions of statutory interpretation de novo. Ass'n of Wash. Spirits & Wine Distribs. v. Wash. State Liquor Control Bd., 182 Wn.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 Wn.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. Id. at 9-19. These rules of statutory interpretation also apply to administrative rules and regu lations. See Overtake Hosp. Ass'n v. Dep't of Health, 170 Wn.2d 43, 51-52, 239 P.3d 1095 (2010).
¶27 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 700-04 (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
¶28 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
¶29 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 Wn.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 stat ute. See id.; Foster, 184 Wn.2d 465. As scientific understanding of water resources has increased, so too have Washington's 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 Wn.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 Wn.2d at 16; Swinomish Indian Tribal Cmty., 178 Wn.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 Wn.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)).
¶30 These legislative priorities continued to change as Washington's population increased and the limitations on its natural resources became more apparent. See Swinomish Indian Tribal Cmty., 178 Wn.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." Id. (citing Laws of 1955, ch. 12, § 75.20.050 (codified as amended at RCW 77.57.020)).
¶31 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 90.22.010. 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 Wn.2d at 591.
¶32 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 90.54.010(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 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.
¶33 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 Wn.2d at 595. Replacing the 1917 policies encouraging "maximum diversion of water" were the modern policies of "Obtaining maximum benefits, prudent management of the state's water resources with input of interested entities, preservation of water within streams and lakes as necessary for instream and natural values, and avoidance of wasteful practices." Id. at 595-96.
¶34 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 and described by 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).
¶35 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 Wn.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 Wn.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.010.
¶36 Importantly, the GMA concentrates future growth into urban growth areas. See RCW 36.70A.110. 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, 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." Id. at 12-13.
¶37 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 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 water and groundwater resources. RCW 36.70A.070(5)(c)(iv).
B. The GMA requires counties to have a comprehensive plan that protects surface water and groundwater resources
¶38 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.
¶39 We begin with the plain language of the statute. Ass'n of Wash. Spirits & Wine Distribs., 182 Wn.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 Wn.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].
RCW 36.70A.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.210," 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 comprehensive plan.
¶40 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 GMA also 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").
¶41 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 Wn.2d at 180.
C. The County's comprehensive plan conflicts with the GMA
¶42 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.
¶43 The GMA places specific requirements on local governments when approving building permits or authorizing subdivisions. See RCW 19.27.097(1); RCW 58.17.110(2). 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 Wn.2d at 179-80.
¶44 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 a showing of factual availability in order to obtain a building permit from the county. Id. 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." Id. 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. Id.
¶45 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.
¶46 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.
¶47 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 also Becky Peterson et al., 2010 WRIA 1 State of the 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.
¶48 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).
¶49 In ruling that the County's comprehensive plan does not provide for the protection of water availability, the Board specifically found amended rural element policies 2DD-2.C.6 and -2.C.7 noncompliant with the GMA. These policies incorporate provisions of the WCC. 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) (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(D)(3) (same), .170(E)(3) (same).
¶50 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 WCC 21.04.090, WCC 21.05.080(3), and WCC 24.11.050, which are WCC 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 42 of the FDO, "[U]ltimately, a building permit for a private single-residential well does not require the applicant to demonstrate that groundwater withdrawal will not impair surface flows."
¶51 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(D)(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.
I). The County's plan fails to protect the availability of water resources
¶52 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 the applicant to demonstrate that groundwater withdrawal will not impair surface flows." FDO at 42. This violates the require ment 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.
¶53 As discussed in Section II.B of this opinion, supra, the County's policies incorporate WCC 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(D)(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. 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, 142 Wn.2d 68.
¶54 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 "[biased 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 Wn.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.
¶55 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 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.
¶56 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. It is wrong under our descrip tion of the proper division of authority set forth in Kitti-tas County: "Ecology is responsible for appropriation of groundwater by permit . . . , the County is responsible for land use decisions that affect groundwater resources." 172 Wn.2d at 180.
¶57 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).
¶58 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(10), protecting groundwater 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 58.17.110.
¶59 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 Wn.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 deter mine 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.
¶60 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 6 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; RCW 58.17.110. " 'Statutes must be interpreted and construed so that all the language is given effect, with no portion rendered meaningless or superfluous.' " G-P Gypsum Corp. v. Dep't of Revenue, 169 Wn.2d 304, 309, 237 P.3d 256 (2010) (internal quotation marks omitted) (quoting State v. J.P., 149 Wn.2d 444, 450, 69 P.3d 318 (2003)); see also Tunstall v. Bergeson, 141 Wn.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.
¶61 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 Wn.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.
¶62 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." Id. 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 Wn.2d at 180-81. This argument rests on a logical fallacy. The GMA requires counties to have a comprehensive plan that protects surface water and groundwater resources, and it requires applicants seeking approval for building permits or subdivision developments to provide that county with evidence of 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 58.17.110. The Board correctly found that the County's plan does not satisfy these requirements.
¶63 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.
¶64 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 Wn.2d at 179.
E. The County plan is inconsistent with our minimum flows jurisprudence
¶65 In addition to the deficiencies it found 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 Wn.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 Wn.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.
¶66 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 Wn.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." Id. at 80-81. "[W]here there is hydraulic continuity and withdrawal of groundwater would impair existing surface water rights, including minimum flow rights, then denial [of a permit] is required." Id. at 93.
¶67 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. Swinomish Indian Tribal Cmty., 178 Wn.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 as signs that task to local governments. See RCW 19.27.097(1); RCW 58.17.110.
¶68 A recent decision from Division One of the Court of Appeals in Fox v. Skagit County, 193 Wn. App. 254, 372 P.3d 784 (2016), petition for review filed, No. 93203-4 (Wash. June 7, 2016), lends further support to the conclusion that counties must 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. Id. 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(1). Id. 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. Id. The opinion in Fox is consistent with our prior decisions in Kittitas County, Swinomish Indian Tribal Community, and Postema, and with our decision today.
¶69 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 "evidence of adequate water supply" As authorized by RCW 90.54.020(3)(a), 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.
¶70 As the Board correctly states, each water use appropriation requires a fact-specific determination. RCW 19.27.097(1); RCW 58.17.110. 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. 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 decisions that consistently protect instream flows from impairment by groundwater withdrawals.
III. The Board Properly Ruled That the County's Rural Element Fails To Comply with the Requirement To Protect Water Quality
¶71 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.
A. Comprehensive plans are not required to include provisions that enhance water quality
¶72 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).
¶73 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 "[p] burning goals" and " [g] eneral declaration of fundamentals" found in RCW 36.70A.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.
¶74 Section .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 [section .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 Wn.2d at 246 (quoting Settle, supra, at 11). Nothing in this plain language suggests that GMA goals impose substantive requirements on local governments.
¶75 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 Wn.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." Id. at 427. In rejecting that argument, we recognized that the term "protect" may encompass an option of enhancement but that the term itself does not require enhancement. Id. 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." Id. 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 Wn.2d at 246. We adhere to that holding here—the GMA does not require counties to "enhance" water quality.
¶76 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 shah 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. . . .
(5) Adequate and safe supplies of water shah 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
¶77 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.
¶78 First, the Board concluded that the County's 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." Id. 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
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 .
Id. at 43. The conclusion that these policies do not protect water quality is not based on a duty to enhance water quality.
¶79 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)." Id. 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. Id. at 37.
¶80 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.
¶81 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 of the Watershed Report; Washington Department of Fish and Wildlife's Land Use Planning for Salmon, Steelhead and Trout, and the Puget Sound Partnership's 2012/2013 Action Agenda for Puget Sound. Peterson et al., supra; Katie Knight, Wash. Dep't of Fish & Wildlife, Land Use Planning for Salmon, Steelhead, and Trout: A Land Use Planner's Guide to Salmonid Habitat Protection and Recovery (2009) (WDFW 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). These reports also determined that " 'stormwater runoff is the leading contributor to water quality pollution of urban waterways in western Washington State.' " Id. at 32 (quoting WDFW 2009 Report, supra, at 39-40).
¶82 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. Id. at 35 (citing Kittitas County, 172 Wn.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 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
¶83 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.
¶84 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 Wn.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.
¶85 RCW 36.70A.302 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.
(Emphasis added.) The legislature's use of the term "may" generally indicates the existence of an option that is a matter of discretion. Nat'l Elec. Contractors Ass'n v. Riveland, 138 Wn.2d 9, 28, 978 P.2d 481 (1999) (citing Yakima County (W. Valley) Fire Prot. Dist. No. 12 v. City of Yakima, 122 Wn.2d 371, 381, 858 P.2d 245 (1993)); see also WAC 365-196-210(20).
¶86 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 non compliance with the GMA, Petitioners have not met the standard for a declaration of invalidity.
FDO at 50 (footnote omitted).
¶87 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 Wn. App. 555, 578, 309 P.3d 673 (2013) (Board's determination of invalidity satisfied the statutory requirements and was based on due consideration of the facts), review denied, 179 Wn.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
¶88 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.

The Nooksack Water Resource Inventory Area, chapter 173-501 WAC.
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 Wn.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. See Futurewise v. Whatcom County, Nos. 05-2-0013 and 11-2-0010c (W. Wash. Growth Mgmt. Hr'gs Bd. Jan. 23, 2014).
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.
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 and described by 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 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.
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, "[T]he 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 hindered by the absence of formal assignment of error." Whatcom County v. W. Wash. Growth Mgmt. Hr'gs Bd., 186 Wn. App. 32, 44, 344 P.3d 1256, review granted, 183 Wn.2d 1008, 352 P.3d 188 (2015). We may review administrative decisions in spite of technical violations when a proper assignment of error is lacking but the nature of the challenge is clear and the challenged finding is set forth in the party's brief. Yakima County v. E. Wash. Growth Mgmt. Hr'gs Bd., 168 Wn. App. 680, 687 n.1, 279 P.3d 434 (2012). Both are present here, and we reach the merits of the County's challenges.
The dissent places undue significance on RCW 19.27.097's location within the state building code. Dissent at 701-02. 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 GMA in 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, 1st Ex. Sess., 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 Wn.2d at 9-11.
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.

The dissent relies on a 1992 attorney general opinion (AGO) to support its conclusion that RCW 19.27.097 does not require proof of the legal availability of water. Dissent at 706-08. We do not read the AGO to support this conclusion. Rather, the AGO recognizes that in order to 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 that 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 Wn.2d 152, 164, 849 P.2d 1201 (1993). Further, we give less deference to such opinions when they involve issues of statutory interpretation. Id. 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.
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 farther appropriations were foreclosed under RCW 90.03.290. 142 Wn.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.''Id. 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.'' Id. at 90.
The decision of the Court of Appeals in Fox was issued after oral argument in the present case had occurred. Petitioners submitted this additional authority to the court for consideration. Appellants' Statement of Additional Auth. 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 Auth. at 1. Respondent asked this court to either reject the statement or, in the alternative, strike all argument from the statement. Id. 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.
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 19.27.097(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.
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.
