    SIDDOWAY, J. — Crown Resources Corporation, owner and operator of the
    Buckhorn Mine, administratively appealed the terms of a federal and state water
    discharge permit issued to it by the Washington State Department of Ecology (Ecology)
    in 2014. The 2014 permit renewed a permit Ecology had initially issued in 2007. The
    Pollution Control Hearings Board (Board) affirmed the 2014 permit,1 and the Ferry
    County Superior Court denied Crown’s petition for judicial review.
    1
    During the administrative appeal of the 2014 permit, Crown identified several
    problems with the permit that were acknowledged by Ecology and the intervenor. The
    problems were corrected by a modified permit issued by Ecology after the hearing, but
    before the Board issued its decision. The record was supplemented and the Board based
    its findings, conclusions, and order on the 2014 permit as modified. Distinctions between
    the original and modified permit are not important to the appeal, so for the most part, we
    refer to the permit in both its original and modified form as “the 2014 permit.”
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    Crown assigns error to the superior court’s order and judgment on grounds that
    three aspects of the 2014 permit are contrary to law, are unsupported by substantial
    evidence, or are arbitrary or capricious: (1) its newly imposed and more stringent final
    water quality effluent limits, (2) interim limits and a 10-month interim compliance period
    imposed before the final limits would take effect, and (3) a new definition and mapping
    of a capture zone that Ecology viewed as merely clarifying a capture zone required by the
    2007 permit. Crown also contends the court erred in upholding the Board’s
    determination that the effective date of the 2014 permit was not stayed during Crown’s
    appeal to the Board.
    Crown has not met its burden of demonstrating that the Board’s order is contrary
    to law, unsupported by substantial evidence, or arbitrary or capricious. We affirm.
    FACTS AND PROCEDURAL BACKGROUND
    The parties to the appeal have over 20 years’ experience with the proposed, and
    ultimately developed, Buckhorn Mine. Crown discovered the gold deposit in the
    Okanogan Highlands in 1988. The mine property is forested and surrounded by national
    forest. The mine was originally proposed to be an open pit mine, by a joint venture to
    which Crown was a party.
    Okanogan Highlands Alliance (OHA), a public interest, not-for-profit
    organization, was formed in 1992 by people living downstream from the mine property,
    in response to the open pit mine proposal. An environmental impact statement (EIS) was
    2
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    completed on that proposal in 1997. In 2000, in a challenge brought by OHA and others,
    the Board reversed a number of Ecology’s water right determinations and a Clean Water
    Act (CWA), 33 U.S.C. § 1341, certification it had issued for the open pit mine.
    Okanogan Highlands Alliance v. Dep’t of Ecology, PCHB Nos. 97-146, -182, -183, -186,
    99-019 (Jan. 19, 2000), 
    2000 WL 46743
    .
    Crown acquired control of the property and, in February 2004, proposed the
    present underground mine. As proposed and developed, the mine project area consists of
    approximately 46 acres of private land. Most of the mine workings are below the water
    table and must be dewatered to enable mining. The mine’s belowground facilities
    include shafts and sumps. Its aboveground facilities include a mine water treatment
    plant, an access road, maintenance shops, ore and development rock stockpiles, and
    detention ponds. Dewatering wells, monitoring wells, surface water monitoring stations,
    and piezometers surround the mine.
    A supplemental environmental review was completed on the underground mine in
    2006. The resulting final supplemental EIS (FSEIS) is the foundational environmental
    document for the current mine. The FSEIS necessarily examined potential water quality
    impacts of the underground mine and proposed and recommended mitigation measures to
    address the impacts, concluding that “[w]hile there is a potential that water quality could
    become degraded, these potential impacts are considered avoidable with the proposed and
    recommended mitigation measures.” Administrative Record (AR) at 3331 (§ 3.17.7),
    3
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    3160 (§ 3.7-72). The FSEIS contemplated that water quality monitoring would occur
    during construction, operations, reclamation, closure, and post-closure—until conditions
    have stabilized below permit limits or water quality criteria. It provided that the
    treatment plant would continue to operate until water quality standards were met.
    On November 1, 2007, Ecology issued to Crown an initial “National Pollutant
    Discharge Elimination System” (NPDES) and “State Waste Discharge Permit” (2007
    permit) under state and federal water quality law.2 The permit authorized the discharge
    of treated mine water and stormwater to four outfalls (Outfalls 001, 002, 003 and 004)
    subject to compliance with specified effluent limits. It also authorized discharges of
    stormwater from industrial areas, undisturbed areas, and nonindustrial areas collected in
    identified storm water retention ponds, detention ponds, and infiltration trenches to
    2
    Washington’s “Water Pollution Control Act,” chapter 90.48 RCW, was enacted
    in 1945 and gave Ecology the responsibility and jurisdiction to control and prevent the
    pollution of waters of the state. RCW 90.48.030. Later amendments to the act make it
    unlawful for any person conducting a commercial or industrial operation of any type to
    dispose of solid or liquid waste material into the waters of the state without obtaining a
    state waste discharge permit. RCW 90.48.160.
    The federal “Water Pollution Control Act,” also known as the CWA, makes it
    unlawful for any person to discharge pollutants from a point source into navigable waters
    of the United States unless the discharge complies with a NPDES permit. 33 U.S.C.
    §§ 1311(a), 1342(a), 1362(12). Congress authorized the Environmental Protection
    Agency (EPA) to delegate the NPDES permit program to states, 33 U.S.C. § 1342(b), and
    Ecology is designated as the state Water Pollution Control Agency for all purposes of the
    CWA in Washington. RCW 90.48.260.
    Ecology regulates water quality under both state and federal law primarily through
    the use of combined NPDES and state waste discharge permits, such as those at issue in
    this case.

    Outfall 002, where it, too, was subject to compliance with specified effluent limits. The
    effluent limits for the end-of-pipe discharges were set at levels equal to State surface and
    groundwater quality standards.
    The 2007 permit required Crown to “establish and maintain a ground water
    capture zone to include all underground mine workings, the surge pond, and all surface
    stockpiles of ore and development rock.” AR at 2028. The 2007 permit also required
    Crown to monitor water quality at identified monitoring wells, surface waters, and seeps
    and springs outside the capture zone. AR at 2025, 2032-35, Conditions S2.B5, S2.C.
    The 2007 permit provided a narrative description of the capture zone but did not include
    a capture zone definition or boundary map. It also did not set numeric compliance limits
    for the monitoring locations outside the capture zone. Ecology used monitoring data to
    determine if the required capture zone was being maintained, however.
    OHA appealed the 2007 permit but settled its appeal within a matter of months,
    agreeing that the mine would proceed, but would provide funding that OHA could use
    (among other things) to monitor the environmental impacts of the mine.
    Permit violations and settlement agreement. Over the first five years of mine
    operation, and beginning in July 2008, Ecology issued Crown six notices of violation,
    two civil penalties, six administrative orders, and one order amendment. Permit
    violations included exceedances of effluent limits for the treatment plant, failure to
    maintain the groundwater capture zone, failure to complete required sampling, and
    5
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    creating slope instability resulting in landslides. Among Crown’s disagreements with
    Ecology’s enforcement actions was Crown’s denial that it had failed to maintain the
    capture zone.
    In July 2012, Ecology issued Crown a $395,000 civil penalty for allegedly causing
    a substantial landslide, failing to maintain the capture zone, and discharging water
    through an electrical control box. Crown appealed the civil penalty. The 2007 permit
    was only months away from expiring and, in contemplation of its renewal, Ecology and
    Crown created a process for developing the permit that would eventually be issued in
    2014. A technical team was formed and tasked with developing terms of a new permit,
    and a policy team was formed to focus on settling the penalty and bringing Crown into
    compliance with the terms of its NPDES permit. The technical team, which included
    staff from Crown and Ecology, Crown’s consultants, and representatives of OHA, met
    approximately 21 times. The 2007 permit was administratively extended during the
    period the technical team worked on the new permit.
    Crown’s appeal of the $395,000 civil penalty was resolved by a “Settlement
    Agreement” filed with the Board on July 1, 2013. The Settlement Agreement released
    Crown from liability under the notice of penalty and Crown agreed, among other things,
    to undertake significant investigation and remedial measures during 2013 and 2014,
    referred to in the Settlement Agreement as the “Water Quality Protection Program.”
    Terms of a renewed permit were still under discussion, and the Settlement Agreement
    6
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    reflected the parties’ understanding that future permit terms would be more stringent,
    stating:
    The Parties anticipate that the new NPDES Permit will include more
    stringent effluent limits, capture zone standards and discharge
    requirements, and that these new standards, particularly background based
    groundwater standards, have the potential to put Crown into immediate
    noncompliance when the new permit is issued. The parties agree that the
    new NPDES permit will contain interim compliance levels and a timeframe
    in which to bring the Buckhorn Mountain Site into compliance with these
    new permit terms.
    AR at 1428.
    The 2014 permit and appeal. On February 27, 2014, after receiving public
    comment on the draft permit, Ecology issued Crown a NPDES and waste discharge
    permit for the five-year term of March 1, 2014, through February 28, 2019. The
    accompanying permit fact sheet described a number of changes from the terms and
    conditions of the 2007 permit. Major changes included (1) the addition of a capture zone
    definition and map, and specific compliance points for testing whether the capture zone
    was being maintained, (2) interim numeric water quality limits that carried forward the
    2007 permit’s water quality criteria-based compliance limits for 10 months (through the
    end of calendar year 2014), and (3) more stringent final numeric effluent limits for
    compliance points outside the capture zone. The more stringent final limits were based
    on a statistical analysis of background (pre-mining) water quality, instead of the State
    water quality criteria-based limits used in the 2007 permit.

    Crown immediately appealed the 2014 permit to the Board. OHA intervened.
    The Board held a seven-day evidentiary hearing beginning on January 26, 2015.
    On matters raised in this appeal and discussed in detail below, Crown presented
    testimony from three consulting experts: hydrogeologist David Banton, hydrogeologist
    Robert Sterrett, and water permitting and statistical expert Owen Reese. Crown also
    presented testimony from its mine general manager Mark Ioli and its environmental
    manager, Gina Myers.
    Ecology presented the testimony of its Unit Supervisor Sanjay Barik, a geochemist
    and environmental engineer, who wrote the 2014 permit. Ecology’s hydrogeologist for
    the Crown project, Lorraine Powell, had retired and was unavailable to testify at the
    hearing, but her deposition was included in the administrative hearing record. OHA
    presented the testimony of Stephen Swope, a hydrogeologist and expert in statistical
    evaluation of groundwater data.
    Ecology conceded some errors in the 2014 permit that were identified during the
    seven-day hearing and issued a modified 2014 permit on April 1, 2015. In July 2015, the
    Board affirmed the 2014 permit as modified in a 46-page findings of fact, conclusions of
    law and order. It found that Crown had failed to meet its burden of proving the invalidity
    of any challenged condition. The Board also rejected Crown’s contention that the 2014
    permit was automatically stayed during pendency of its appeal to the Board. The Board
    8
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    ruled that because Crown did not move for a stay, the terms of the 2014 permit as
    modified were effective 30 days after it was issued.
    Crown petitioned for judicial review of the Board’s decision and, in March 2017,
    following a hearing de novo, the Ferry County Superior Court denied Crown’s petition
    for review and affirmed the Board’s findings, conclusions, and order in all respects.

    Assignments of Error
    Crown assigns no error to any of the Board’s 69 findings of fact. Only one of its
    assignments of error—its challenge to the superior court’s order affirming the Board’s
    conclusion that the 2014 permit was not stayed during the appeal to the Board—presents
    a pure issue of law. Its assignment of error to the court’s order affirming the Board on
    the matters of the final limits, the interim limits and compliance schedule, and the capture
    zone conditions, require us to review whether the Board’s findings of fact fail to support
    its conclusions.

    Crown Resources Corp. v. Dep’t of Ecology
    We begin with Crown’s challenge to the 2014 permit’s definition and mapping of
    the capture zone because our resolution of the parties’ disagreement on that issue bears
    on other assigned errors.
    I.     CROWN DOES NOT MEET ITS BURDEN OF DEMONSTRATING THAT THE 2014
    PERMIT’S DEFINITION AND MAPPING OF A CAPTURE ZONE IS UNSUPPORTED BY
    SUBSTANTIAL EVIDENCE OR IS ARBITRARY OR CAPRICIOUS
    The 2014 permit retains the 2007 permit’s requirement to maintain a groundwater
    capture zone, but Ecology sought to clarify the purpose and extent of the zone by
    including a definition of the term and mapping its boundary. The now-defined capture
    zone is described as “represent[ing] the farthest extent from the mine that mine-related
    contaminants in groundwater and surface water are allowed.” AR at 1115, Condition
    S1.A.2. The condition also provides that “[t]he Permittee must capture and treat mine
    generated contaminated groundwater and industrial stormwater inside the Capture Zone
    perimeter so that surface and groundwater outside the Capture Zone does not exceed [the
    permit’s effluent] limits.” 
    Id. Crown contends
    there is no scientific basis for using Ecology’s definition and
    mapping of a boundary on the surface area within which Crown must capture all mine-
    impacted water. Review of the FSEIS reveals that there are two possible understandings
    of the 2007 permit’s identification of a capture zone.
    The modeling that Ecology used to demark the capture zone boundary in the 2014
    permit came from two places: modeling for the FSEIS prepared in connection with the
    12
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    original permitting of the mine and updated modeling following mine operations by
    Golder Associates, Crown’s consultants. The modeling for the FSEIS was prepared by
    an Ecology contractor, URS, and is contained in a September 2006 report entitled
    “Regional Three-Dimensional Groundwater Flow Model of Buckhorn Mountain.” AR at
    3383. Section 5.4.3 of the report explains that “[a]s mining proceeds and groundwater is
    extracted to dewater bedrock in the mined zone and provide water for consumptive uses,
    a capture zone will develop around the mine.” AR at 3446. It describes the capture zone
    as
    represent[ing] the surface area over which recharge would be captured by
    the mine. This is recharge that would either seep into the mine workings or
    would be extracted using pumping wells.
    AR at 3446-47.
    URS presumably had in mind a technical, hydrologic concept of a capture zone,
    discussed hereafter. But its conclusion that development of the capture zone would result
    in a discernible surface area below which the mine would capture all contaminated water
    meant that the capture zone it modeled could serve as a regulatory concept as well.
    Crown’s hydrology expert, David Banton of Golder Associates, Inc., testified that
    the URS model assumed that any water that did not run off the surface would make its
    way down and be captured by the dewatering wells in the underground mine. He testified
    that the assumption that water infiltrating below the surface would make its way
    vertically to within the footprint of the capture zone did not prove to be true, however.
    13
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    He described the evidence collected through test pits and holes that Golder Associates
    had drilled during mine operation as “show[ing] that there are these low permeability
    perching horizons that do direct some water horizontally.” Report of Proceedings (RP) at
    727. Crown’s briefing on appeal describes the FSEIS’s modeling of the capture zone as
    “outdated.” Appellant’s Br. at 41 n.14.
    According to Mr. Banton (and to Robert Sterrett, Crown’s hydrogeology expert)
    the technical hydrology term “capture zone” is not a surface area concept. Mr. Banton
    described the hydrologic concept of a “capture zone” as
    the point where water would flow to the underground mine sumps or the
    dewatering wells on one side of the line, and on the other side of the line,
    the water is moving away, the groundwater within bedrock is moving away
    to ultimately feed streams or wetlands.
    RP at 754. He explained that consistent with the science of hydrology, his capture zone
    modeling says nothing about surface area, but evaluates only the deep bedrock
    groundwater system—levels several hundred feet below ground—that would be
    influenced by the pumping of the mine dewatering wells. He testified it did not include
    water in the shallow subsurface, or “vadose” zone.
    Treating “capture zone” as having this narrow scientific meaning, Crown’s staff
    and consultants view the 2007 permit as not imposing any regulation on discharges of
    contaminated water moving horizontally through the vadose zone. Accordingly, they
    view the definition and mapping in the 2014 permit as a major change.
    14
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    Ecology’s and OHA’s representatives in the permitting process had a different
    understanding of “capture zone” as used in the 2007 permit. Given the assumptions of
    the FSEIS modeling, the URS report supported using the capture zone it described as a
    regulatory concept, since it identified the surface area under which all water
    contaminated by mine operations would be captured and treated. As Ecology points out,
    the short narrative mention of the capture zone in the 2007 permit describes it as
    including features located aboveground:
    The Permittee must establish and maintain a ground water capture zone to
    include all underground mine workings, the surge pond, and all surface
    stockpiles of ore and development rock.
    AR at 2028 (emphasis added). And Ecology points out that the 2007 permit cannot be
    read as leaving discharges of contaminated water that move horizontally through the
    vadose zone as unregulated. The discharge limitation provision of the 2007 permit states
    that “[t]he discharge of any” identified pollutant at a level in excess of that identified and
    authorized by the permit constitutes a violation. AR at 2025 (emphasis added). The
    permit contemplates discharges only at the four outfalls. This is consistent with the intent
    of the FSEIS that all contaminated mine water would be captured and treated and that
    water quality impacts from the mine would be “avoided” through mitigation measures.
    AR at 3331.
    Sanjay Barik, the Ecology unit supervisor who wrote the 2014 permit, testified

    of the FSEIS. Ecology’s former hydrogeologist for the Buckhorn project, Lorraine
    Powell, shared Mr. Barik’s understanding that even under the 2007 permit, Crown was
    required to capture all contaminated surface or groundwater from any source that is
    inside the capture zone boundary. This includes vadose zone water, and perched or
    seasonal water tables.
    The Board’s findings are mindful of Mr. Banton’s opinion that capture zone refers
    to a cone of depression in the area of vertically moving deep groundwater, which would
    not include water in the vadose zone that moves horizontally and is not affected by
    dewatering wells.3 In specifically finding that the capture zone definition in the 2014
    permit was supported by substantial evidence, the Board implicitly rejected Mr. Banton’s
    understanding in favor of Mr. Barik’s competing explanation that the capture zone was
    always relied on as a regulatory demarcation extending up to the land surface and
    encompassing all mine-contaminated water.
    Crown nevertheless contends that it proved it is not technically feasible to meet
    the 2014 capture zone requirement with respect to vadose zone water that travels
    3
    Crown points to the fact that in section 3.7 of the FSEIS, dealing with “Water
    Resources,” it speaks of the capture zone map as representing a modeled cone of
    depression created by pumping dewatering wells and sumps at the site, consistent with a
    hydrologic concept rather than a regulatory concept. Elsewhere in section 3.7 of the
    FSEIS, however, it specifically contemplates that water seeping from surface stockpiles
    of ore and development rock and groundwater in the shallow subsurface vadose zone
    would be captured through additional mitigation measures if needed. For capture
    purposes, the FSEIS does not differentiate between different types of groundwater,
    whether shallow or deep, and does not exclude vadose zone water.

    horizontally or is “perched” and cannot be captured by dewatering wells. Ecology
    counters that Crown proved no such thing—it failed to identify any specific area of
    shallow subsurface water within the capture zone that it is not possible to capture and
    treat. It points to Mr. Banton’s testimony that Crown has installed a shallow dewatering
    well (SDW-12) and several trenches in order to capture this water, with plans for more.
    The Board expressly referenced the Banton testimony in its findings, noting Crown’s
    installation of trenches to capture water moving horizontally in the upper layer.
    And Mr. Barik opined that Crown can comply with the capture zone as mapped in
    the 2014 permit. He testified that Crown can capture contaminated groundwater by
    adding dewatering wells and can capture interflow water in the vadose zone by adding
    more trenches, as planned by Crown, that hone in on preferential pathways of the water.
    Ms. Powell testified similarly about measures available or currently in use to capture
    contaminated water, including stormwater conveyances, placing linings underneath
    portions of the stockpiles to channel the captured water, dewatering wells, and the mine
    workings themselves where water is pumped out and processed. She testified that
    “perched” water is included in the regulatory definition of groundwater that Crown must
    capture. See WAC 173-200-020(12).
    Crown’s final challenge to the 2014 permit’s capture zone mapping is that
    Ecology drew the line in such a way that some Ecology-approved facilities fall outside
    the line, placing Crown immediately out of compliance. It argues that this makes the
    17
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    arbitrariness of the capture zone “particularly evident.” Appellant’s Br. at 43. But both
    Mr. Barik and Ms. Powell explained that compliance with the effluent limits is
    determined at compliance locations, not at monitoring locations around the capture zone.
    Mr. Barik testified that none of the compliance points fall within the facilities about
    which Crown expresses concern. In closing argument to the Board, Ecology’s counsel
    reiterated the agency’s interpretation and intention to cite only for violations at
    compliance points and not at monitoring locations.
    Crown has not shown as a practical matter that the capture zone boundary, as
    Ecology interprets and promises to enforce it, is arbitrary or capricious. It has not shown
    that the Board’s affirmance of the 2014 permit’s definition and mapping of the capture
    zone is not supported by substantial evidence.
    II.    CROWN DOES NOT MEET ITS BURDEN OF DEMONSTRATING THAT THE INTERIM
    LIMITS AND COMPLIANCE SCHEDULE ARE CONTRARY TO LAW, UNSUPPORTED BY
    SUBSTANTIAL EVIDENCE, OR ARBITRARY OR CAPRICIOUS
    As earlier recounted, the 2007 permit authorized Crown to discharge treated mine
    water and treated stormwater at four designated outfalls. These “end-of-pipe” discharges
    from the treatment plant were subject to effluent limits derived from state water quality
    standards for groundwater and surface water.
    The 2007 permit also required Crown to monitor groundwater and surface water
    quality at designated monitoring wells (MW), dewatering wells, surface monitoring
    stations, and seeps and springs. Although these were not compliance points, Ecology
    18
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    used the monitoring results as the basis for determining whether there had been a failure
    of the capture zone.
    The 2014 permit for the first time included numeric compliance limits for surface
    and groundwater quality at points in the environment outside the capture zone. Because
    this is the first permit to impose numeric limits at those locations, the 2014 permit
    provided a 10-month compliance schedule—from March 1 to December 31, 2014—
    during which interim limits would apply. Mr. Barik testified that Ecology chose the 10-
    month compliance period to allow for one spring freshet (thaw and runoff period), which
    he believed would provide Crown enough time to comply with the final limits. With
    limited exceptions not pertinent to the appeal, the interim limits for the groundwater and
    surface water monitoring locations carried forward the treatment plant, end-of-pipe,
    effluent limits from the 2007 permit.4 In instances where the interim limit would be more
    stringent than the final limit, the final limit would apply.
    WAC 173-201A-510(1) generally provides that waste discharge permits, whether
    issued pursuant to the NPDES or otherwise, must be conditioned so the discharges
    authorized will meet the water quality standards. Subsection (4) of the regulation
    allowed Ecology to issue a schedule for achieving compliance with the chapter’s water
    quality criteria on a case-by-case basis, however, providing that such “[s]chedules . . .
    4
    Specific locations with high pre-mining levels of arsenic, manganese, and total
    suspended solids were identified and exempted from compliance with the interim or final
    limits.

    No. 35199-8-III

    shall be developed to ensure final compliance with all water quality-based effluent limits
    in the shortest practicable time.” WAC 173-201A-510(4)(a).5 The interim effluent limits
    are required to be formally established, “based on the best professional judgment of the
    department.” WAC 173-201A-510(4)(b).
    Crown contends that Ecology did not use its best professional judgment because it
    failed to consider actual site conditions when setting interim limits that Crown contends
    are unachievable. It also contends that Ecology failed to consider what time period
    would be practicable for meeting the new final limits when it established the 10-month
    compliance schedule.
    The site conditions that Crown contends Ecology failed to consider were pre-
    mining natural background water quality conditions in the environment and the effects of
    mine activities that Crown characterizes as “previously authorized” by Ecology. Crown’s
    concept of Ecology’s “previously authorized” activities is based on its position that
    before the 2014 permit, its only obligation was to treat for contaminated water located in
    the narrowly defined hydrology capture zone. We agree with the Board’s finding that
    Ecology reasonably understood the 2007 permit to require all contaminated water from
    mine operations to be collected, treated, and discharged through outfalls subject to the
    state water quality effluent limits, however. As Ecology points out, any pollution above
    5
    WAC 173-201A-510 was partially amended in 2016. The parties do not contend
    the changes are relevant to this appeal. See Br. of Appellant at 28 n.10.
    20
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    those limits was not a result of activities authorized by Ecology; it was a result of
    Crown’s permit violations.
    Even though Ecology concedes that the capture zone language of the 2007 permit
    required clarification in the 2014 permit, the 2007 permit clearly required Crown to
    maintain specified “sampling locations” in both surface and groundwater in the
    environment. AR at 2032, 2034, Conditions S2.B.5, S2.C. As a matter of logical
    interpretation of the 2007 permit (and consistent with WAC 173-201A-510(1)’s
    requirement that permits be conditioned to meet water quality standards), the 2007 permit
    limits—which are equal to the state water quality standards—applied at the designated
    sampling locations. Otherwise, there would have been no way to ensure compliance with
    the capture zone. Ecology consistently interpreted and applied the 2007 permit in this
    fashion, twice penalizing Crown for capture zone failures.
    Ecology also contends that the anti-backsliding provision of the CWA constrained
    Ecology in setting interim limits. The anti-backsliding provision prohibits permits from
    being “renewed, reissued, or modified . . . to contain effluent limitations which are less
    stringent than the comparable effluent limitations in the previous permit.” 33 U.S.C.
    § 1342(o)(1); see Port of 
    Seattle, 151 Wash. 2d at 604
    (“NPDES permits are subject to an
    21
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    ‘anti-backsliding’ provision, which does not allow a subsequent NPDES permit to create
    a lesser effluent limitation.”).6
    The 2014 permit’s interim limits for compliance points in the environment are, for
    practical purposes, “comparable [to the] effluent limitations in the previous permit” and,
    therefore, cannot be less stringent under the CWA’s anti-backsliding rule. 33 U.S.C.
    § 1342(o)(1). Communities for a Better Environment v. State Water Resources Control
    Board, 
    132 Cal. App. 4th 1313
    , 1330-31, 
    34 Cal. Rptr. 3d 396
    (Cal. Ct. App. 2005),
    which Crown cites as holding that the anti-backsliding rule does not apply when a less
    stringent interim limit is not comparable to the final limit in a prior permit, is therefore
    inapposite.7
    6
    Crown incorrectly contends that Ecology did not raise the CWA anti-backsliding
    rule below and that it was not part of the Board’s decision. Ecology relied on the anti-
    backsliding rule in its prehearing brief and closing argument. In conclusion of law 2, AR
    at 1482, the Board’s decision referred to the CWA and its prohibition against discharge
    of any pollutant unless done in compliance with the CWA and/or an NPDES permit. The
    Board cited to 33 U.S.C. § 1342, which contains the anti-backsliding provision. Thus,
    the Board’s decision comports with the requirement that its decision is supported by
    rationale in the administrative record. See Aviation W. Corp. v. Dep’t of Labor & Indus.,
    
    138 Wash. 2d 413
    , 446, 
    980 P.2d 701
    (1999).
    7
    Crown argues for the first time in its reply brief that the “new interim limits that
    Ecology applied to groundwater in the environment are not ‘effluent limitations’ that
    govern discharges from point sources to navigable waters, and therefore are not subject to
    the CWA anti-backsliding provision.” Appellant’s Reply Br. at 26 n.12. We decline to
    consider this issue argued for the first time in the reply brief. To address issues argued
    for the first time in a reply brief is unfair to the respondent and inconsistent with the rules
    on appeal. See Ainsworth v. Progressive Cas. Ins. Co., 
    180 Wash. App. 52
    , 78 n.20, 322
    22
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    The Board found that the record contains substantial evidence supporting the
    interim effluent limits. It found that using the 2007 permit’s end-of-pipe effluent limits
    as the basis for the interim limits was not unreasonable and was within Ecology’s
    discretion. The Board’s findings support its conclusion that Crown failed to carry its
    burden of establishing the invalidity of the interim discharge limits, implicitly
    determining that Crown failed to demonstrate that Ecology did not use its best
    professional judgment in setting the interim limits. WAC 173-201A-510(1).
    The 10-month period for compliance presents a closer question. The Board’s
    findings cite Mr. Barik’s testimony that from early 2012, Ecology communicated to
    Crown that the renewed NPDES permit would include numeric limits for monitoring
    locations outside the capture zone and a compliance schedule applicable to those limits.8
    It found that for several years, Crown had been aware of existing contaminates related to
    its prior discharges from the treatment plant as well as elevated sulfate concentrations in
    MW-14. It found that prior violations had already caused the parties to put in place the
    Water Quality Protection Program. It found that the July 2013 Settlement Agreement
    P.3d 6 (2014); RAP 10.3(c) (reply brief should be limited to a response to the issues in
    the brief to which the reply brief is directed).
    8
    In fact, Mr. Barik testified that “Ecology made very clear starting from fall of
    2011” that new limits would be based on background water quality, not state water
    quality criteria, and “it’s fair to say that Crown was aware of this position three year[s]
    ahead of time even before the permit was issued.” RP at 1140.
    23
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    memorialized the parties’ understanding that the NPDES permit under discussion would
    contain interim limits and a compliance schedule.
    The Board cited Mr. Barik’s testimony that the 10-month period would allow for
    one more spring freshet to occur, which would provide time for existing contaminants
    from Crown’s previous discharges to flush through the system, and that the 10-month
    time frame provided sufficient time for the installed improvements to come on line and
    benefit water quality.
    Crown complains that the Board did not make any findings explaining its rejection
    of its witnesses’ testimony that it could not practicably meet the final limits in a 10-
    month period. But the Board’s findings reflect its consideration of Crown’s witnesses’
    testimony that 10 months did not give it sufficient time to realize the intended positive
    effects of the Water Quality Protection Program. It recognized that Crown proposed that
    the interim limits remain in effect until July 2017, to allow for three spring freshet
    periods and provide time to evaluate Crown’s compliance with the interim limits after
    which the parties would discuss whether a permit modification was needed. We can infer
    from the lack of additional findings that the Board rejected Crown’s scientific testimony
    in favor of Ecology’s explanation why the 10-month period was appropriate. See, e.g.,
    Pilling v. E. & Pac. Enters. Trust, 
    41 Wash. App. 158
    , 165, 
    702 P.2d 1232
    (1985) (absence
    of finding on a material issue is presumptively a negative finding against the party with
    the burden of proof).

    And Ecology provides extensive argument as to how the record and Crown’s own
    inaction refutes its science-based lack of feasibility claims. It argues that Crown’s
    argument that its “legacy” pollution was authorized by the discharge permissions in the
    2007 permit lacks factual or legal support. It points out that Crown did not, as a factual
    matter, discharge to state water quality levels for most constituents. It gives the example
    of sulfate, whose treatment plant discharge rate has been below 50 mg/L since June 2009,
    a level that cannot explain documented sulfate levels above 250 mg/L in Gold Bowl
    Creek and elsewhere. It also argues that Crown did not provide calculations or specific
    analysis of the extent or lasting time of its legacy pollution, i.e., it did not document the
    fate and transport of contaminants historically discharged from the treatment plant.
    Crown’s experts testified that 10 months was insufficient time to address
    contamination from its use of construction fill material that is leaching sulfate into the
    groundwater, but Ecology argues that their claim to need more time is undermined by
    Crown’s own actions, since Crown controlled how it placed the construction fill, the type
    of fill used, and how quickly it responded to its discovery in 2010 that the fill was
    contributing to significant groundwater pollution.
    It appears that the Board agreed with Ecology that Crown should not receive
    regulatory cover through an extended compliance schedule for what Ecology calls
    Crown’s poor compliance record and inadequate attempts at adaptive management.

    Based on the competing evidence, reasonable minds could differ on whether the
    10-month period is too short. “Where there is room for two opinions, and the agency
    acted honestly and upon due consideration, this court should not find that an action was
    arbitrary and capricious, even though this court may have reached the opposite
    conclusion.” Port of

    .
    III.      WE WILL NOT CONSIDER CROWN’S UNPRESERVED CHALLENGE TO AN ALLEGED
    FAILURE BY ECOLOGY TO CONDUCT AN AKART ANALYSIS; CROWN DOES NOT
    DEMONSTRATE THAT THE FINAL LIMITS ARE CONTRARY TO LAW, UNSUPPORTED BY
    SUBSTANTIAL EVIDENCE, OR ARBITRARY OR CAPRICIOUS
    As documented in the FSEIS, the background water quality for ground and surface
    water at Buckhorn generally exceeds the numeric criteria in State water quality standards.
    Although Ecology did not use background water quality as the basis for the effluent
    limits in the 2007 permit, it chose background water quality as the basis for the final
    effluent limits in the 2014 permit in order to be consistent with the state antidegradation
    policy as expressed in RCW 90.54.020(3)(b) and to ensure Crown’s maintenance of the
    capture zone.
    RCW 90.54.020 provides a “general declaration of fundamentals” that shall guide
    utilization and management of the waters of the State. It declares an antidegradation
    policy:
    (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
    26
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    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.
    RCW 90.54.020 (emphasis added). Ecology’s regulations repeat and implement this
    policy, providing that where background water quality exceeds the numeric standards
    listed in Ecology’s regulations, no measurable change may be allowed to water quality
    without a specific finding that lowering the water quality is necessary and in the
    overriding public interest. WAC 173-200-030(2)(c) (groundwater); WAC 173-201A-
    320(1) (surface water).
    The final effluent limits in the 2014 permit are based on a statistical analysis of a
    pre-mining background water quality data set gathered at Buckhorn Mountain during the
    EIS development process from 1990 through 2007. Stephen Swope, OHA’s
    hydrogeologist and expert in statistical analysis for groundwater data, performed the
    analysis, relying on Ecology and EPA guidance documents.
    Crown maintains that Ecology’s regulations and formal guidance establish a two-
    step process Ecology must follow in establishing limits when the existing water quality is
    better than State water quality criteria. It argues that both steps were violated in setting
    the final limits in the 2014 permit. It describes the first step as properly determining
    27
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    existing background water quality and the second step as establishing an enforcement
    limit somewhere between background and the State criteria based on an “AKART”
    evaluation of what water quality can be practicably and reasonably achieved.
    “‘AKART’ is an acronym for ‘all known, available, and reasonable methods of
    prevention, control, and treatment.’” WAC 173-201A-020.9 Crown argues that at step
    one, Ecology used inappropriate background values. It argues that Ecology simply
    ignored step two by failing to conduct an AKART analysis evaluating what water quality
    levels could be practicably or reasonably achieved.
    A.       Crown’s argument that Ecology failed to perform an AKART analysis is
    raised for the first time on appeal and will not be considered
    We turn to the second contention first because Ecology and OHA object that an
    alleged failure by Ecology to perform an AKART analysis is improperly raised for the
    first time on appeal. RCW 34.05.554 generally provides that issues not raised before the
    agency may not be raised on appeal. 
    Bowers, 103 Wash. App. at 597-98
    (“RCW 34.05.554
    precludes appellate review of issues not raised below.”). Our own rules also require issue
    preservation. RAP 2.5(a). Crown responds that it did raise the issue before the Board,
    but since the Board did not address the issue in its otherwise thorough decision, we have
    our doubts and turn to the record.
    9
    WAC 173-201A-020 goes on to provide that “AKART shall represent the most
    current methodology that can be reasonably required for preventing, controlling, or
    abating the pollutants associated with a discharge. The concept of AKART applies to
    both point and nonpoint sources of pollution.”

    Crown’s allegedly new argument is that “Ecology must . . . set limits ‘as near the
    natural groundwater quality as practical,’” and, “In determining what limits are practical
    to achieve, Ecology must undertake an ‘AKART’ analysis.” Appellant’s Br. at 15
    (quoting WAC 173-200-050(3)(a)(ii)) (alteration in original). But Crown’s “Proposed
    Legal Issues and List of Witnesses and Exhibits” filed with the Board did not identify as
    an issue any alleged failure by Ecology to comply with WAC 173-200-050(3)(a)(ii) or an
    alleged failure to perform an AKART analysis. See AR at 363-69. The Board’s
    “Prehearing Order” identifies issues “submitted and agreed to” by the parties, “which will
    govern the case,” and does not identify an alleged failure by Ecology to comply with
    WAC 173-200-050(3)(a)(ii) or prepare an AKART analysis. See AR at 378-80. Neither
    AKART nor the second step of an asserted two-step process is addressed in Crown’s
    prehearing brief. See AR at 914-29. Crown did argue in its prehearing brief that Ecology
    used the background values themselves as enforcement values, not as a base on which to
    determine enforcement values, AR at 922, but it did not identify any regulation or
    guidance that it contended was required but not followed.
    In reply to Ecology’s and OHA’s contention that this issue was waived, Crown
    cites testimony or argument appearing in 9 pages of the 1,382-page transcript of
    proceedings. Appellant’s Reply Br. at 12. Only the testimony of Owen Reese, Crown’s
    consulting water resources engineer, merits discussion. Read as a whole, it is clear that
    Mr. Reese did not assert that Ecology failed to follow any particular required procedure
    29
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    in setting the final limits in the 2014 permit. He merely observes that the 2014 permit is
    atypical because the enforcement limit imposed is the same as background water quality.
    Mr. Reese appears implicitly to concede that performing an AKART analysis is
    the responsibility of the permittee, not the Department of Ecology, 10 something that
    Ecology points out is the position taken in its “Implementation Guidance for the Ground
    Water Quality Standards.” See AR at 2729, 2795 & 2799 (“The permittee must complete
    an AKART evaluation.”) and 2796 (“The permittee should describe all possible treatment
    technology alternatives, including the effective treatment levels and the costs associated
    with each technology.”). And in response to questioning by two Board members, Mr.
    Reese concedes that an AKART analysis can support treating background water quality
    as the enforcement limit, although more typically it will not. The final questioning by
    Board members makes it clear that Mr. Reese did not claim that AKART would have
    required a higher enforcement limit in this case:
    Q.     [By Board member Tom Morrill] And is that part of your comment
    or a determination that AKART can’t get you to background?
    A.     I haven’t done an AKART determination, unfortunately.
    Q.     So your questioning about having those limits set at background is
    just—that’s not how you would normally see it, but it’s not based on
    specific issues with the site?

    Q.        Just so I’m clear, Mr. Morrill asked you questions about setting of
    using background, and I thought I heard you first say you should—
    and using the word never is not very helpful—you should not set the
    enforcement limit at background, and then you later said that if
    AKART gets you to background, then you can use background as
    the enforcement limit. Or did I misunderstand?
    A.        No, I think you’re right. I think my later statement is more correct,
    that if AKART and if the technologies can get you to background,
    then the enforcement limit would be there.
    AR at 904-05 (emphasis added).
    Ecology and OHA have major disagreements with Crown over Crown’s
    interpretation of the language “as practical” appearing in WAC 173-200-050(3)(a)(ii), the
    relationship between AKART and the antidegradation policy, and who—Ecology or the
    permittee—is responsible for undertaking any AKART analysis. None of these
    disagreements were presented to or resolved by the Board. Witnesses were not
    questioned about how these issues, correctly resolved, would apply to the 2014 permit.
    We will not consider Crown’s contention for the first time on appeal that by failing to
    undertake an AKART analysis, Ecology failed to comply with WAC 173-200-
    050(3)(a)(ii).
    B.       Crown does not meet its burden of demonstrating that background values
    were determined contrary to law, were unsupported by substantial evidence, or
    are arbitrary or capricious
    Crown did present and preserve the argument that Ecology erred in the initial step
    of determining background water quality conditions by using an incorrect statistical
    31
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    analysis that deviated from its regulations and Implementation Guidance. Ecology’s
    Implementation Guidance11 explains that the statistical analysis for background water
    quality will differ depending upon whether the data set is parametric (normal distribution)
    or nonparametric (i.e., does not follow a normal bell curve). The parties agree that in this
    case, the data is nonparametric because it was collected from several locations over
    different time periods.
    The Implementation Guidance states generally that background water quality “is
    statistically defined as the 95 percent upper tolerance interval with a 95% confidence.”
    AR at 2803 (emphasis omitted). It also provides, however, that in cases of nonparametric
    data, the maximum value in the data set is used as the upper tolerance limit and defines
    background water quality. Despite this, Ecology, relying on Mr. Swope’s work, used the
    95 percent upper tolerance interval with 95 percent tolerance. Crown argues that by
    using this measure rather than the maximum value as the upper tolerance limit, Ecology
    11
    Ecology developed its earlier-mentioned Implementation Guidance as an
    advisory and interpretative statement for implementing chapter 173-200 WAC for
    activities, such as mines, that are required to receive a State waste discharge permit. The
    Implementation Guidance document states that it is not a regulation, but is intended as a
    general guide to facilitate consistent statewide issuance of permits. It is not intended to
    be inclusive or address every circumstance at every facility. The specific requirements
    will depend on each facility and its unique situation. See RCW 34.05.230(1); Wash.

    has “essentially guarantee[d] a 5% false positive rate, even if there were no mining-
    related impacts.” Appellant’s Reply Br. at 15.
    Mr. Swope explained his seeming disregard of the Implementation Guidance. He
    testified that the narrative in the Implementation Guidance on which Crown relies applies
    to data sets with 59 or fewer samples, which was the expected norm at the time the
    narrative was prepared. If a data set has more than 59 samples, then the highest value
    does not have to be used to achieve a 95 percent coverage. The data set used by Mr.
    Swope had significantly more than 59 samples. Mr. Swope further testified that the 95
    percent upper tolerance interval with a 95 percent confidence method is used throughout
    the industry and its use is consistent with Ecology’s and EPA’s guidance. As the Board
    found, even Crown’s expert, Mr. Reese, agreed that the method is commonly used to
    calculate background. Beyond being scientifically acceptable, it has the advantage of
    balancing the risk of false positives and false negatives.
    The Board found that the record contains ample evidence supporting the final
    limits and that Crown did not meet its burden of proving that the methodology employed
    to derive the final effluent limits was inappropriate. It found that while Ecology
    recognized the potential for false positives, “it appropriately balanced that risk against the
    risk of false negatives.” AR at 1478-79.

    IV.    THE SUPERIOR COURT PROPERLY AFFIRMED THE BOARD’S CONCLUSION THAT THE
    EFFECTIVENESS OF THE 2014 PERMIT WAS NOT STAYED DURING THE BOARD
    APPEAL
    Finally, Crown contends that the effective date of the 2014 permit was
    automatically stayed under RCW 34.05.422(3) during the pendency of its appeal to the
    Board. The Board concluded that under that statute, the 2014 permit took effect on the
    last day to file an appeal with the Board—which was 30 days after issuance—and in
    order to obtain a stay beyond that point, Crown needed to file a motion for stay with the
    Board. The superior court affirmed the Board’s decision that because Crown did not file
    a motion for stay, the terms of the modified 2014 permit were effective 30 days after its
    issuance.

    Crown Resources Corp. v. Dep’t of Ecology
    We find no conflict between the provisions of the APA and chapter 43.21B RCW,
    which created the “Environmental and Land Use Hearings Office” and prescribes the
    jurisdiction of the Board, its membership, and many of its procedures.
    RCW 34.05.422(3), the APA provision relied on by Crown, states:
    When a licensee has made timely and sufficient application for the renewal
    of a license or a new license with reference to any activity of a continuing
    nature, an existing full, temporary, or provisional license does not expire
    until the application has been finally determined by the agency, and, in case
    the application is denied or the terms of the new license limited, until the
    last day for seeking review of the agency order or a later date fixed by order
    of the reviewing court.
    The statute’s provision that “an existing . . . license does not expire until the
    application has been finally determined by [Ecology]” had application in this case, when
    Ecology administratively extended Crown’s 2007 permit until its application for a new
    license was finally determined on February 27, 2014. The Board has recognized the
    application of RCW 34.05.422(3) in this context. E.g., Ellensburg Water Co. v. Dep’t of
    Ecology, PCHB no. 86-153, 
    1990 WL 151750
    at *6 (Feb. 2, 1990); Okanogan Highlands
    Alliance v. Dep’t of Ecology, PCHB no. 04-064, 
    2005 WL 878023
    at *7 (Apr. 12, 2005).
    Crown argues that the last clause of RCW 34.05.422(3) also applies because the
    terms of its original 2014 permit applied to activity of a continuing nature and in issuing
    the permit, Ecology imposed terms that were more limiting than the terms of its prior,
    2007 permit. We accept that proposition. As applied to Crown, its then-existing 2007
    permit did “not expire . . . until the last day for seeking review of the [Ecology] order.”
    35
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    See RCW 34.05.422(3). Consistent with this clause, the Board held that the 2007 permit
    did not expire until the last day for seeking Board review of Ecology’s issuance of the
    2014 permit.
    Crown seemingly argues that because Ecology and the Board are both agencies,
    we should read RCW 34.05.422(3) as applied in this case as if the term “agency” means
    “Ecology” the first time “agency” is used in the statute, and means “Board” the second
    time “agency” is used, with the result that its 2007 permit would not expire “until the last
    day for seeking review of the [Board] order.” See RCW 34.05.422(3). That is not how
    we construe the same word used in a single statute, however. E.g., State v. Gonzalez, 
    168 Wash. 2d 256
    , 264, 
    226 P.3d 131
    (2010) (When similar words are used in different parts of
    a statute, the meaning is presumed to be the same throughout.). Yet, Crown argues that
    only by reading the second use of the word “agency,” as meaning “Board,” can we avoid
    rendering meaningless the language that follows: “or a later date fixed by order of the
    reviewing court.” See RCW 34.05.422(3).
    Crown overlooks a critical fact: administrative appeals to a second agency are not
    the norm under the APA, and the APA does not undertake to address the different
    procedures that apply in the atypical case where an administrative appeal to a second
    agency is required. The APA contemplates only stages of review within a single agency
    or judicial review. Under the stand-alone application of the APA, RCW 34.05.422(3)’s
    reference to an order of the reviewing court makes sense. What makes no sense is to
    36
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    construe the APA to provide that in the case of all other permits and licenses, limitations
    in a newly limited permit or license would be suspended for the short period of time
    within which to obtain judicial review, but limitations in a newly limited permit issued by
    Ecology would be suspended for what might be a one-year long, or longer, proceeding
    before the Board.
    Administrative review of Ecology decisions by the Board is addressed first and
    foremost by chapter 43.21B RCW. RCW 43.21B.010 provides that the “purpose of the
    pollution control hearings board is to provide for a more expeditious and efficient
    disposition of designated environmental appeals as provided for in RCW 43.21B.110.”
    Members of the Board are required under RCW 43.21B.020 to be “qualified by
    experience or training in pertinent matters pertaining to the environment.” They acquire
    additional expertise in performing their statutory duties. Dioxin/Organochlorine Ctr. v.
    Dep’t of Ecology, 
    119 Wash. 2d 761
    , 776, 
    837 P.2d 1007
    (1992).
    The APA provides that “[n]othing in this chapter may be held . . . to limit or repeal
    additional requirements imposed by statute.” RCW 34.05.020. The Board applied
    RCW 43.21B.310(2), which provides that “[a]t any time during the pendency
    of an appeal of . . . an order to the board, the appellant may apply pursuant to
    RCW 43.21B.320 to the hearings board for a stay of the order,” and RCW 43.21B.320(1),
    which provides that a person appealing an order that has not been stayed by the issuing
    agency “may obtain a stay of the effectiveness of that order only as set forth in this
    37
    No. 35199-8-III
    Crown Resources Corp. v. Dep’t of Ecology
    section.” (Emphasis added.) A prima facie case for stay is made “if the applicant
    demonstrates either a likelihood of success on the merits of the appeal or irreparable
    harm.” RCW 43.21B.320(3). Crown did not move for a stay in the manner required by
    RCW 43.21B.320. The Board refused to treat the 2014 permit as stayed.
    This would appear to be required by the plain language of the provision, but
    Crown argues that the plain meaning of “order” as used in RCW 43.21B.310 and .320
    does not include licenses and permits—Crown even argues that provisions of chapter
    43.21B RCW “repeatedly distinguish” between “orders” on the one hand, and “permits or
    licenses” on the other. Appellant’s Reply Br. at 35. We disagree. The APA defines the
    unqualified term “order” as meaning “a written statement of particular applicability that
    finally determines the legal rights, duties, privileges, immunities, or other legal interests
    of a specific person or persons.” RCW 34.05.010(11)(a). A license or permit is plainly
    “a written statement of particular applicability that finally determines the legal . . .
    privileges . . . of a specific person or persons.” 
    Id. Indeed, it
    is hard to imagine calling
    an order that determines someone’s “legal . . . privileges” anything other than a license or
    permit.
    And RCW 43.21B.110 does not repeatedly distinguish between orders and
    licenses. It favors the generic “decisions” in describing matters that the Board has
    jurisdiction to hear and decide. It only uses the term “orders” in identifying
    particular orders, under specific statutes, that fall within its appellate jurisdiction.
    38
    No. 35199-8-III
    Crown Resources Corp. v. Dep 't of Ecology
    RCW 43.21B.110(l)(b), G). While RCW 43.21B.230(3)(c) speaks of an "order, permit,
    license, or decision" being appealed, that reference alone does not justify treating the four
    terms as mutually exclusive. "License" means and includes a "permit" under the AP A.
    RCW 34.05.010(9)(a). And rather than treat "decision" as excluding an order, permit, or
    license, RCW 43.2 lB.110 treats "decision" as all-encompassing. Just as a permit is a
    license and orders, permits, and licenses are decisions, a permit is an order. And see
    Dioxin/Organochlorine 
    Ctr., 119 Wash. 2d at 777
    n.59 (holding that the appellant was
    required to appeal Ecology's NPDES decision to the Board, and noting that
    RCW 43.21B.320 grants the Board authority to issue a stay).
    As did the superior court, we uphold the findings, conclusions, and order of the
    Board. The superior court's final order and judgment is affirmed.
    A majority of the panel has determined this opinion will not be printed in the
    Washington Appellate Reports, but it will be filed for public record pursuant to
    RCW 2.06.040.
