    -ooOoo-
    This is one of several current disputes between Malaga County Water District
    (Malaga) and the Central Valley Regional Water Quality Control Board (Water Quality
    Board). In this instance, Malaga desired a wastewater discharge permit allowing it to
    discharge 0.85 million gallons per day (mgd) into certain disposal ponds. The Water
    Quality Board says the permit issued to Malaga allowed just that. And the trial court that
    heard Malaga’s petition for a writ of mandate agreed. Yet, in unusually aggressive and at
    times unnecessarily caustic language, Malaga argues the Water Quality Board is playing
    games, that its staff are deliberately providing false testimony, and that the permit issued
    actually limited Malaga to discharging 0.49 mgd. Malaga requests we set aside the trial
    court’s decision that the permit allowed a discharge of 0.85 mgd.
    We note at the outset that Malaga’s aggressive approach seems misplaced in this
    instance. In our review of the record, we see nothing that meaningfully distinguishes the
    underlying issues in this case from the many administrative hearings and processes we
    regularly review. While certain cases could turn on such posturing, this is not one of
    them. Indeed, as the Water Quality Board points out, the position Malaga took could
    have resulted in terminating a permit that allowed it to operate and replacing it with one
    that Malaga admits is insufficient to continue its current operations. It is unclear to us
    why litigation of this type was necessary when alternative administrative procedures
    could have resolved this issue in a faster and more efficient manner.
    The case is somewhat unique, though; both on the merits and in its procedural
    posture. The trial court resolved this case by interpreting the disputed permit as initially
    allowing the 0.85-mgd discharge, subject to verification of certain information by the
    Water Quality Board’s executive officer. In doing so, it determined the verification
    process did not amount to a modification of the permit and thus did not constitute an
    improper delegation of authority from the Water Quality Board to its executive officer.
    Substantively, delegation issues are not frequently raised and thus there is little relevant
    case law to rely upon. Procedurally, as a result of its decision, the trial court determined
    all remaining issues need not be resolved and thus did not reach procedural and due
    process concerns surrounding the underlying permitting process raised by the parties.
    Despite this, both parties spend extended time arguing whether Malaga properly
    exhausted its administrative remedies such that it can argue its procedural issues at all,
    and whether any of those alleged procedural failures warrant vacating the permit.
    2.
    Further, in the time this case has been pending, Malaga’s permit has expired and a new
    permit has issued, regulating Malaga’s conduct going forward and allegedly cutting off
    any potential liability for past conduct. This has raised fresh arguments the case is moot.
    In this opinion, we conclude that the primary issue raised in this case is
    sufficiently important to warrant the use of our discretion to hear issues that are
    technically moot. That issue is whether the verification process included in Malaga’s
    permit constituted an improper delegation of authority from the Water Quality Board to
    its executive officer. Upon review, we conclude that it did. We do not, however, reach
    Malaga’s or the Water Quality Board’s remaining issues, because those issues were not
    part of the trial court’s final judgment, were not resolved in the first instance by the trial
    court, and are thus insufficiently developed to determine whether they could either
    support the trial court’s judgment or require vacating the entire permit issued.
    Accordingly, for the reasons set forth below, we reverse the trial court’s judgment and
    remand for further proceedings.
    FACTUAL AND PROCEDURAL BACKGROUND
    The trial court’s statement of decision contains a detailed summary of the facts
    leading to the main dispute it resolved. As none of those facts are meaningfully contested
    on appeal, we generally rely on them here, adding additional factual and procedural
    details relevant to our decision.
    Malaga owns and operates a wastewater treatment facility in Fresno County,
    providing sewer service primarily to industrial and nondomestic users. As part of its
    operations, Malaga discharges certain types of treated wastewater into disposal ponds (in
    the case of undisinfected secondary treated wastewater), or in some instances, into a
    canal owned and operated by the Fresno Irrigation District (in the case of disinfected
    tertiary treated wastewater discharged when the canal contains irrigation water
    deliveries). The average flow of water treated by Malaga between 2010 and 2013 was
    0.65 mgd.
    3.
    Malaga’s discharge of treated wastewater is legally governed by both California
    and federal laws. The Water Quality Board is the entity tasked with permitting and
    regulating Malaga’s activities under both legal frameworks. Between 2008 and 2013,
    Malaga’s activities were regulated under order No. R5-2008-033, adopted by the Water
    Quality Board renewing Malaga’s waste discharge requirements (the requirements
    imposed by California law) for its National Pollutant Discharge Elimination System
    (NPDES) permit No. CA0084239 (the permit required under federal law). The waste
    discharge requirements and permit were enforced, as is normally the case, with a separate
    cease and desist order (order No. R5-2008-0032). We refer to these documents as the
    2008 permit for ease of reference.
    Under the 2008 permit, Malaga could discharge 0.85 mgd of undisinfected
    secondary treated wastewater into the disposal ponds, which were identified as Discharge
    Point 002. This 0.85 mgd number is technically referred to as an effluent flow limitation.
    The canal was separately permitted and identified as Discharge Point 001. The relevant
    permits are required to be renewed every five years, with the renewal triggered by
    Malaga filing a report of waste discharge.
    Malaga timely submitted its report of waste discharge in September 2012. In
    response, around August 2013, the Water Quality Board asked Malaga for additional
    information concerning the capacity of its disposal ponds to ensure compliance with
    certain terms of the 2008 permit. Malaga’s response stated Malaga was “in the planning
    process to develop a schedule to isolate one or more of the ponds to confirm and monitor
    percolation capacity,” although it also provided a chart showing some disposal capacities
    and percolation rates. Seemingly finding this response inadequate, staff working on the
    renewal permits apparently turned to information from 2008 suggesting the maximum
    capacity of the disposal ponds was 0.49 mgd.
    In August 2014, the Water Quality Board sent Malaga drafts of a new waste
    discharge requirement, NPDES permit, and cease and desist order. These draft
    4.
    documents contained a proposed modification to the discharge limitation for the disposal
    ponds, stating that a maximum discharge of 0.49 mgd would be allowed. A second draft
    was circulated for public review on September 26, 2014, and a hearing on the matter was
    set in December 2014. At this point, a flurry of information was exchanged between
    Malaga and the Water Quality Board. Malaga submitted updated information supporting
    its request for a 0.85-mgd discharge limit on October 27, 2014, was told that information
    did not conform to Water Quality Board requirements, and then submitted conforming
    documents on November 3, 2014. On December 2, 2014, Malaga submitted additional
    information in the form of a disposal pond capacity matrix.
    In written notes submitted prior to and in testimony at the December 2014 hearing,
    staff for the Water Quality Board stated they had not had enough time to review Malaga’s
    submissions. The staff continued to recommend a 0.49-mgd limit but noted in their draft
    that “if review of the technical information provided supports a higher effluent flow
    limitation to the disposal ponds, this Order allows the Executive Officer to approve a
    higher effluent flow limitation.” Counsel for Malaga appeared at the December 2014
    hearing, where evidence was submitted by Water Quality Board staff and their counsel.1
    Following the hearing, the Water Quality Board issued renewed waste discharge
    requirements (order No. R5-2014-0145), a new NPDES permit (permit No. CA0084239),
    and an updated cease and desist order (order No. R5-2014-0146), which we refer to as the
    2014 permit. The 2014 permit set the permitted discharge rate into the disposal ponds at
    0.49 mgd, effective February 1, 2015, but allowed an increase in the permitted discharge
    rate up to 0.85 mgd, subject to the approval of the Water Quality Board’s executive
    1       Malaga and the Water Quality Board raise several issues with the procedural aspects of
    this hearing. However, as we do not reach these issues, we recite relevant facts related to these
    procedural issues if the need arises and do not lay them out in detail.
    5.
    officer and provided Malaga presented the Water Quality Board with specific data
    identified in the 2014 permit.2
    Malaga contends it was later summoned to a meeting with the Water Quality
    Board’s executive officer where it provided no new information, yet later received a letter
    from the executive officer increasing the permitted effluent flow to 0.85 mgd. The Water
    Quality Board contends Malaga submitted additional information on December 29, 2014,
    January 5, 2015, and January 12, 2015. The Water Quality Board agrees, however, that
    its executive officer then issued a letter that effectuated the 0.85-mgd effluent flow
    limitation. This letter issued on January 21, 2015.
    Malaga filed a petition for review with the State Water Resources Control Board
    and, later, on December 31, 2014, filed the present writ of mandate action. The trial
    court provided its tentative ruling on the writ of mandate on December 16, 2016, and,
    after additional disputes between the parties, issued its statement of decision on April 17,
    2017.
    As noted above, the trial court concluded that this case turned exclusively on
    whether an effluent flow limitation of 0.85 mgd had been properly permitted by the
    Water Quality Board or whether that flow rate constituted an improper delegation of
    authority.3 It summarized the four issues before it as follows:
    “1.    Whether the Executive Officer’s letter affected a change to the permit by
    increasing the flow rate to the disposal ponds.
    2       We recount the exact language of the permits as needed in our discussion of the merits.
    3       In its statement of decision, the trial court wrote that a finding of improper delegation
    would entitle Malaga to a writ of mandate commanding the Water Quality Board to set aside the
    2014 permit. Although we find an improper delegation in this case, we do not order the trial
    court to issue a writ of mandate. This is so because the trial court could potentially determine
    Malaga’s claims are barred for other reasons or that only certain portions of the 2014 permit
    should be set aside. As the court found the delegation was valid, it did not reach any disputes
    regarding exhaustion, procedural fairness, or evidentiary support for the permit raised in this
    case. Nor has it had an opportunity to consider whether additional facts have mooted the case.
    We leave it to the trial court to resolve any such remaining disputes in the first instance.
    6.
    “2.    Whether the [2014] permit is impermissibly premised solely on hearsay and
    whether the [Water Quality] Board disregarded unimpeached undisputed
    evidence presented.
    “3.    The Order does not conform to Topanga Ass[n.] [F]or a Scenic Community
    v. County of Los Angeles (1974) 
    11 Cal.3d 506
    , 516–517.
    “4.    [Water Quality] Board violated the Administrative Procedures [sic] Act,
    which requires reversal of their decisions.”
    In analyzing the first issue, the trial court determined a “fair argument could be
    made that the granting of exemptions by an executive officer is tantamount to delegating
    to the executive officer the power to modify or revoke the regional water quality control
    plan as to the entity to which such an exemption is granted.” However, after reviewing
    two primary cases, Hampson v. Superior Court (1977) 
    67 Cal.App.3d 472
    , 483
    (Hampson) and Russian River Watershed Protection Committee v. Santa Rosa (9th Cir.
    1998) 
    142 F.3d 1136
    , 1143 (Russian River), and the language of the permit, the court
    concluded the 2014 permit did not improperly delegate authority to the executive officer.
    Rather, the court found the permit granted “an effluent discharge rate of 0.49 mgd at
    [D]ischarge [P]oint 002, but also permitted a discharge rate of up to 0.8[5] mgd,
    conditioned upon the approval of the Executive Officer” with “specific guidance to
    [Malaga] and to the Executive Officer as to that which would be required of [Malaga] to
    obtain such approval.” Reviewing the subsequent history, the court then found that
    Malaga had, in fact, requested the higher effluent discharge rate and that “approval by the
    Executive Officer of the higher of the two effluent discharge rates provided in the 2014
    [permit], as requested by [Malaga] and upon presentation by [Malaga] to the [Water
    Quality Board] of the specific data identified in the 2014 [permit], constitutes
    implementation by the Executive Officer of the 2014 [permit], and not the issuance,
    modification, or revocation of such orders.”
    7.
    After reaching this conclusion, the trial court declared the action was moot. This
    was so, according to the court, because “the 0.49[-]mgd discharge rate was never in
    effect,” and thus Malaga was “never at risk of violating the maximum flow rate by
    discharging effluent into the ponds in excess of the allowable maximum.” The court
    found that as of the effective date of the 2014 permit, Malaga “has been authorized to
    discharge to the on-site disposal ponds at the rate of 0.85 mgd under the terms and
    conditions” of the 2014 permit. The court concluded that no relief could be afforded to
    Malaga, mooting its claims.
    Finally, the court added a brief ruling on a pending motion to strike portions of the
    administrative record. There, the court stated it was “unable to identify any document
    which was submitted as part of the Administrative Record which should not properly be a
    part of the Administrative Record and which would have any effect on the ultimate
    determination by the Court to deny the Petition for Writ of Mandate on the grounds that
    the relief requested by [Malaga] is now moot.” This appeal timely followed.
    While this case was pending, on January 31, 2020, Malaga’s 2014 permit expired.4
    On February 20, 2020, the Water Quality Board issued Malaga a new waste discharge
    requirement permit. The 2020 permit alleged Malaga no longer discharged wastewater
    into a specific canal, which eliminated the need for a federal NPDES permit, and thus
    purported to only comprise a state waste discharge requirement permit. The 2020 permit
    purported to permit a discharge to on-site disposal ponds that “shall not exceed a monthly
    average flow of 0.85 mgd.”
    4        On July 27, 2020, the Water Quality Board filed a motion to dismiss this appeal, arguing
    it was moot, and a related request for judicial notice of Malaga’s 2020 waste discharge
    requirement permit. In its opposition to the motion to dismiss, Malaga stated it had no objection
    to this court taking judicial notice of the permit, although it argued hearsay facts within the
    document could not be accepted as true. Malaga further requested we take judicial notice of the
    record in case No. F078327, an appeal from sanctions allegedly imposed under the 2008 and
    2014 permits. Upon review, we conclude it proper to take judicial notice of the 2020 permit and
    the record in case No. F078327.
    8.
    DISCUSSION
    In this case, we are tasked with resolving two significant disputes. First, whether
    this case is moot, either on the grounds identified by the trial court or on the grounds
    raised in the Water Quality Board’s motion to dismiss. Second, if the case is to proceed,
    whether the Water Quality Board improperly delegated its authority to its executive
    officer in this instance. On the first dispute, we decline to specifically resolve whether
    this case is moot. While the Water Quality Board is correct that Malaga no longer faces
    the prospect of a citizen suit for its past discharges in violation of the 0.49-mgd discharge
    limitation, issues exist regarding whether the overall relief sought by Malaga would
    affect the sanction proceedings on appeal in case No. F078327, such that a later finding
    that the permit was improper on any of the grounds not previously reached by the trial
    court below and thus must be vacated, would still afford Malaga relief in this action. We
    take no position on whether the case is, in fact, moot. Rather, assuming that to be the
    case, we exercise our discretion to resolve the dispute before us because it is one of broad
    public interest that is likely to recur. On the second dispute, we conclude that the
    delegation of authority to increase Malaga’s permitted effluent flow discharge rate based
    on the submission of additional technical evidence is an improper delegation of authority.
    We thus reverse the trial court’s judgment and remand this case so the court can
    determine whether any further proceedings are necessary given the potential mootness of
    the case.
    Mootness Arguments
    There are several mootness arguments raised in this case. The first arises
    because the trial court concluded this case was moot given the 2014 permit, in
    combination with the executive officer’s letter, granted Malaga a 0.85-mgd effluent
    discharge limitation prior to the effective termination of its prior permit, leaving no relief
    available under the writ of mandate. We do not agree. “ ‘The pivotal question in
    determining if a case is moot is … whether the court can grant the plaintiff any effectual
    9.
    relief. [Citations.] If events have made such relief impracticable, the controversy has
    become “overripe” and is therefore moot.’ [Citation.] By the same token, an appeal is
    moot if ‘ “the occurrence of events renders it impossible for the appellate court to grant
    appellant any effective relief.” ’ ” (Lockaway Storage v. County of Alameda (2013)
    
    216 Cal.App.4th 161
    , 174–175.) As we have noted, according to our forthcoming
    analysis, the 2014 permit did not grant Malaga a 0.85-mgd effluent discharge limit
    because the authorization for that flow rate was improperly delegated to the executive
    officer. Accordingly, the trial court’s judgment cannot be affirmed on this ground.
    The briefing also contained a second mootness argument, where the Water Quality
    Board argued we should conclude this matter is moot on the premise that there is no case
    or controversy existing with respect to discharge into the disposal ponds. More
    specifically, in response to arguments made by Malaga, the Water Quality Board argued
    that disposal ponds are exempt from the Federal Water Pollution Control Act, as they are
    not waters of the United States, and thus there is no risk of citizen suits against Malaga
    under that law. The argument went on to contend that citizen suits are not permitted
    under California law, eliminating any potential harm to Malaga.
    Even if this contention is correct, a question that turns on factual issues regarding
    the nature of the disposal ponds that was not resolved by the trial court, the Water Quality
    Board’s mootness argument was unavailing at the time the case was filed. As discussed
    below, the 2014 permit contained an express right to discharge 0.49 mgd and an
    improperly delegated authority to increase that flow to 0.85 mgd. Malaga then conceded
    that it could not operate without violating the law under a 0.49-mgd limitation, writing
    “Malaga is not complying with the [0].49[-]mgd limitation, because it cannot.” At a
    minimum then, the 2014 permit placed Malaga in a position where it could not legally
    continue to operate due to a permit that Malaga contends is the result of legally improper
    practices. Regardless of the possibility of a citizen suit, Malaga’s suit could relieve
    Malaga of the claim it has been operating in violation of the law if Malaga’s claims
    10.
    succeeded; particularly so if Malaga’s claims ultimately resulted in vacating the permit.
    As the permit has now expired, however, it appears this argument has at least partially
    merged into the arguments made in the Water Quality Board’s motion to dismiss.
    In that motion, the Water Quality Board argues that the 2014 permit has now
    expired; legally precluding any federally authorized citizen suits arising from past
    conduct under the permit. (See Gwaltney v. Chesapeake Bay Foundation, Inc. (1987)
    
    484 U.S. 49
    , 52 [federal suits alleging wholly past violations precluded].) Malaga
    responds by arguing that its claims are not meant merely to protect against federal citizen
    suits, but to prevent state enforcement actions under the 2014 permit, claiming case
    No. F078327, also pending in this court, demonstrates the need for such action. The
    Water Quality Board replies that this contention is wholly new and unbriefed, and thus
    improper at this stage. It further contends that, factually, Malaga’s claim is incorrect
    because case No. F078327 relates to a prior 2008 permit and not to the 2014 permit.
    We decline to resolve these disputes. “ ‘Ordinarily, … when a case becomes moot
    pending an appellate decision “the court will not proceed to a formal judgment, but will
    dismiss the appeal.” ’ ” (County of Fresno v. Shelton (1998) 
    66 Cal.App.4th 996
    , 1005.)
    “There are, however, times when the appellate court may wish to examine the issues on
    appeal despite the occurrence of events which render the appeal moot.” (Id. at p. 1006.)
    Thus, several exceptions to the general rule of dismissal exist, one of which “grants the
    appellate court the discretion to decide a case which, although technically moot, poses an
    issue of broad public interest that is likely to recur.” (Ibid.) We conclude this exception
    is appropriate to utilize in this case.
    In this case, Malaga contests the Water Quality Board’s actions in modifying
    requirements for the permits issued under both federal and state water laws. Whether the
    Water Quality Board may, in fact, leave such decisions to its executive officer is a matter
    of broad public interest involving the operation of governmental agencies and potential
    impacts on the environment and public wastewater treatment plants. Further, the limited
    11.
    five-year timeframe of the permits at issue (see Wat. Code,5 § 13378), coupled with the
    inherent delays in complex litigation such as this which typically arises after
    administrative proceedings, means that similar delegations of authority may evade review
    if mootness is strictly enforced. Accordingly, here we exercise our discretion to hear the
    matter even if moot. We expressly leave open any factual disputes regarding mootness,
    leaving those to the trial court upon remand given that our resolution means the court will
    also be faced with additional claims previously raised by Malaga that it chose not to
    reach upon concluding the 2014 permit did not include an improper delegation of
    authority. The trial court will be in the best position to resolve any mootness arguments
    at that time.
    Delegation of Authority
    Having exercised our discretion to hear this case, we next turn to whether the
    Water Quality Board improperly delegated its authority to its executive officer in this
    case. As we have previously noted, we conclude it did.
    Standard of Review
    Decisions made by the Water Quality Board or the State Water Resources Control
    Board may be reviewed by way of a writ of mandate. (§ 13330, subds. (a), (b).) These
    writ proceedings are governed by Code of Civil Procedure section 1094.5. (§ 13330,
    subd. (e).) In such proceedings, the trial court’s review “shall extend to the questions of
    whether the respondent has proceeded without, or in excess of, jurisdiction; whether there
    was a fair trial; and whether there was any prejudicial abuse of discretion.” (Code Civ.
    Proc., § 1094.5, subd. (b).) An abuse of discretion can occur three different ways:
    (1) “the respondent has not proceeded in the manner required by law”; (2) the “decision
    is not supported by the findings”; or (3) “the findings are not supported by the evidence.”
    (Ibid.)
    5         All further statutory references are to the Water Code unless otherwise indicated.
    12.
    With regard to the relevant issues on appeal, Malaga’s primary contention is that
    the Water Quality Board acted in excess of its jurisdiction by delegating its authority to
    modify a permit to its executive officer in violation of section 13223. As the Water
    Quality Board’s authority to act turns on the interpretation and application of this statute
    to the permit issued, we undertake a de novo review of its action. (See Hoag Memorial
    Hospital Presbyterian v. Kent (2019) 
    36 Cal.App.5th 413
    , 421 [“ ‘If a question of law is
    presented, we undertake a de novo review of the [Department’s] ruling’ ”]; Hoitt v.
    Department of Rehabilitation (2012) 
    207 Cal.App.4th 513
    , 522 [“Issues of law raised in a
    petition for a writ of administrative mandate, including the interpretation of applicable
    statutes or regulations, are for the courts to resolve de novo”].)
    Overview of Relevant Laws
    The laws relevant to this appeal are part of a “complicated web of federal and state
    laws and regulations concerning water pollution” that have been discussed in many cases.
    (City of Rancho Cucamonga v. Regional Water Quality Control Bd. (2006)
    
    135 Cal.App.4th 1377
    , 1380.)
    At the federal level, Malaga’s water discharges can be regulated by the Federal
    Water Pollution Control Act (Clean Water Act; 
    33 U.S.C. § 1251
     et seq.). “Part of the
    federal Clean Water Act is the National Pollutant Discharge Elimination System
    (NPDES), ‘[t]he primary means’ for enforcing effluent limitations and standards under
    the Clean Water Act. [Citation.] The NPDES sets out the conditions under which the
    federal [Environmental Protection Agency] or a state with an approved water quality
    control program can issue permits for the discharge of pollutants in wastewater.
    [Citations.] In California, wastewater discharge requirements established by the regional
    boards are the equivalent of the NPDES permits required by federal law.” (City of
    Burbank v. State Water Resources Control Bd. (2005) 
    35 Cal.4th 613
    , 621.)
    The Clean Water Act covers discharges into waters of the United States, a broad
    but not unlimited category of navigable and closely related bodies of water. (See
    13.
    Garland v. Central Valley Regional Water Quality Control Bd. (2012) 
    210 Cal.App.4th 557
    , 561–563 [providing overview of federal dispute regarding the meaning of waters of
    the United States].) It makes such discharges illegal without a proper NPDES permit.
    (Id. at p. 561.)
    California adopted the Porter-Cologne Water Quality Control Act (§ 13000 et
    seq.) to ensure that its state-level water laws were adequate to meet “the necessary federal
    requirements to ensure [California] would obtain [United States Environmental
    Protection Agency] approval to issue NPDES permits.” (Building Industry Assn. of San
    Diego County v. State Water Resources Control Bd. (2004) 
    124 Cal.App.4th 866
    , 875.)
    In doing so, it statutorily defined the term “ ‘waste discharge requirements’ ” to be the
    equivalent of the term “ ‘permits’ ” as used in the relevant federal law. (§ 13374.)
    California’s state-level water laws regulate persons “discharging waste, or
    proposing to discharge waste, within any region that could affect the quality of the waters
    of the state” by requiring them to file a report of the discharge with the appropriate
    regional board. (§ 13260, subd. (a).) Upon receipt of this filing, the regional board “after
    any necessary hearing, shall prescribe requirements as to the nature of any proposed
    discharge, existing discharge, or material change in an existing discharge … with relation
    to the conditions existing in the disposal area or receiving waters upon, or into which, the
    discharge is made or proposed. The requirements shall implement any relevant water
    quality control plans that have been adopted, and shall take into consideration the
    beneficial uses to be protected, the water quality objectives reasonably required for that
    purpose, other waste discharges, the need to prevent nuisance .…” (§ 13263, subd. (a).)
    This action creates the waste discharge requirements that may also constitute an NPDES
    permit. Parallel state law provisions require reporting discharges or proposed discharges
    into the navigable waters of the United States and, with slight variations, subjects those
    reports to the same proceedings as discharges that could affect the quality of the waters of
    the state. (See §§ 13376–13378.)
    14.
    Persons affected by the waste discharge requirements issued by the regional board
    may petition for review or revision of those requirements, although the regional board
    must review them periodically regardless. (§ 13263, subd. (e).) Notably, “[n]o discharge
    of waste into the waters of the state, whether or not the discharge is made pursuant to
    waste discharge requirements, shall create a vested right to continue the discharge. All
    discharges of waste into waters of the state are privileges, not rights.” (§ 13263,
    subd. (g).)
    Relevant to this case and the process by which waste discharge requirements are
    issued or modified, under section 13223, subdivision (a): “Each regional board may
    delegate any of its powers and duties vested in it by this division to its executive officer
    excepting only the following: (1) the promulgation of any regulation; (2) the issuance,
    modification, or revocation of any water quality control plan, water quality objectives, or
    waste discharge requirement; (3) the issuance, modification, or revocation of any cease
    and desist order; (4) the holding of any hearing on water quality control plans; and (5) the
    application to the Attorney General for judicial enforcement but excluding cases of
    specific delegation in a cease and desist order and excluding the cases described in
    subdivision (c) of Section 13002 and Sections 13304 and 13340.”
    The Authority Granted the Executive Officer Was Improperly Delegated
    The trial court’s ruling in this case turned on whether the 2014 permit improperly
    delegated authority to the executive officer to modify the terms of the waste discharge
    requirement’s effluent discharge limitation. We thus start with the permit’s language.
    The 2014 permit states: “The average monthly discharge flow shall not exceed the
    following: [¶] … [¶] b. 0.49 mgd at Discharge Point 002, unless the Executive Officer
    approves a higher flow, up to 0.85 mgd, as allowed by Provision VI.C.2.b.” Provision
    VI.C.2.b. provides: “As described in Attachment F - Fact Sheet, Section II.B.3, the
    estimated disposal capacity of the ponds (Discharge Point 002) is approximately
    0.49 mgd. This Order restricts the flow to Discharge Point 002 to 0.49 mgd as an average
    15.
    monthly. Order R5-2008-0033 included an effluent flow limitation to Discharge Point
    002 of 0.85 mgd, as an average monthly. The Discharger may request an increase in flow
    at Discharge Point 002, up to 0.85 mgd. The request for the increase in flow must
    include supporting calculations and documentation showing the ponds have enough
    capacity for reliably disposing of the requested average monthly flow. At minimum, the
    request must address the percolation rate and how the rate was determined. The request
    must also include a proposed maintenance program for the disposal ponds, which shall
    include an ongoing schedule for performing maintenance work to maintain adequate
    disposal capacity. The increased flow will be subject to Executive Officer approval, and
    the Discharger may not discharge at the higher flow rate until any and all proposed
    maintenance work has been completed and the request for an increase in flow has been
    approved by the [Water Quality Board’s] Executive Officer.”
    Reviewing this language, the trial court concluded no improper delegation of
    authority occurred because under Hampson and Russian River, the permit had properly
    drawn the line between delegating the power to issue, modify, or revoke a permit and
    delegating the power to grant exemptions provided certain conditions were met. We do
    not agree with this parsing of the case law.
    In Hampson, the court was considering a writ of prohibition filed by the California
    Regional Water Quality Control Board, Lahontan Region (Lahontan Board) and its
    executive officer, Hampson, seeking to enjoin the superior court from proceeding on a
    writ of mandate filed by the real party in interest, Walker. (Hampson, supra,
    67 Cal.App.3d at p. 475.) In analyzing this issue, the court was faced with a difficult
    procedural question concerning whether Walker had properly exhausted his
    administrative remedies before seeking the writ of mandate. (Id. at p. 480.)
    The underlying merits of the case involved a claim by Walker that the Lahontan
    Board had improperly denied Walker’s request for an exemption to a water control plan
    that prohibited the construction of individual septic tanks and leach fields in certain areas.
    16.
    (Hampson, supra, 67 Cal.App.3d at pp. 475, 478.) The plan, as adopted, authorized “the
    executive officer to grant exemptions from the prohibition upon proof by the dischargee
    that the proposed design will not result in pollution or nuisance.” (Id. at p. 478.) Walker
    had requested an exemption from Hampson who, instead of granting or denying it, took
    the issue to the Lahontan Board for a vote. (Id. at p. 479). That vote denied the
    exemption request. (Ibid.)
    Walker did not seek administrative review of the vote denying his exemption
    request, which led to a claim by the Lahontan Board and Hampson that Walker had failed
    to exhaust his administrative remedies. (Hampson, supra, 67 Cal.App.3d at p. 475.) In
    response, Walker argued that the Lahontan Board and Hampson were estopped from
    arguing the exhaustion issue. Walker claimed he had previously come to some form of
    an agreement, not fully described in the case, with Hampson that worked as a final
    administrative decision on the exemption request. Walker argued Hampson’s later
    decision to bring the request to the Lahontan Board for a vote was taken in bad faith and
    that the Lahontan Board was bound by the prior agreement and thus estopped from
    arguing failure to exhaust administrative remedies. (Id. at pp. 479–480.)
    Although the court was clear that it was not reaching the merits of the underlying
    dispute, it was required to discuss the authority of the board to delegate exemption
    authority to Hampson in order to resolve the procedural issues before it. (Hampson,
    supra, 67 Cal.App.3d at pp. 476, 483.) On this issue, it wrote: “Although resolution
    75-5 which was adopted as an addendum to the regional water quality control plan
    authorized the executive officer to grant exemptions provided certain conditions were
    met, it did not, and could not, delegate its power and duty to issue, modify, or revoke any
    water control plan, water quality objection or waste discharge requirement. ([]§ 13223.)”
    (Id. at p. 483.) The court further wrote: “Consequently, even though the resolution
    authorized the executive officer to make the initial determination as to whether the
    landowner had met the prerequisites for an exemption, the regional board could not
    17.
    relinquish its right and duty to overrule such preliminary determination if it determined
    that to grant an exemption would constitute a modification of the water control plan or
    the waste discharge requirement included in that plan.” (Id. at p. 484.) Utilizing this
    view, the court determined no estoppel could occur because Walker could not properly
    rely on an agreement with the executive officer that exceeded that officer’s legally
    authorized powers. In other words, the court held that an exemption granted by the
    executive officer would violate section 13223 as an improper delegation, that Walker was
    chargeable with the knowledge of such a fact, and thus that Walker could not rely on any
    alleged agreement with Hampson. (Hampson, at pp. 483–484.)
    It is in analyzing this case that the trial court’s reasoning went astray. While the
    trial court concluded Hampson “drew the distinction between delegating to the executive
    officer the power to issue, modify, or revoke, on the one hand, and delegating to the
    executive officer the power ‘to grant exemptions provided certain conditions were met,’
    on the other,” the case did not actually go so far. Rather, Hampson follows the direct
    premise set out in section 13223, that under no circumstances may the relevant water
    board delegate authority that would result in issuing, modifying, or revoking a waste
    discharge requirement. The Hampson court’s analysis implies that where such a
    delegation is made, the most that delegation can create is an opportunity for the executive
    officer to review the materials submitted and recommend to the board that those materials
    either meet or fail to satisfy the requirements for issuing, modifying, or revoking a waste
    discharge requirement. The final legal authority rests in the board itself, and the law is
    clear enough on this point that persons dealing with the board are presumed to know this
    fact.
    With this in mind, cases like California Assn. of Sanitation Agencies v. State
    Water Resources Control Bd. (2012) 
    208 Cal.App.4th 1438
     (Sanitation Agencies) and
    Russian River are readily understood as defining one of the boundary lines for
    determining whether an improper delegation of power has occurred—whether the
    18.
    decision modifies the terms of the permitted action or merely serves to determine how to
    enforce those terms. In Russian River, the underlying NPDES permit contained a
    discharge limit of one percent of the flow of the Russian River after it initially reaches a
    flow of 1,000 cubic feet per second, a location at which to measure this flow, and an
    identification of specific limitations on the discharge of effluents. (Russian River, supra,
    142 F.3d at p. 1139.) It did not, however, identify a method for measuring either of these
    limits. (Ibid.) In Sanitation Agencies, a disputed water plan contained a provision stating
    that “ ‘[t]otal identifiable persistent chlorinated hydrocarbon pesticides shall not be
    present in the water column at concentrations detectable within the accuracy of analytical
    methods approved by the [EPA] or the Executive Officer [of the Regional Board].’ ”
    (Sanitation Agencies, at p. 1464.) Both cases involved challenges to the delegation of
    authority to the executive officer to determine how to measure or otherwise monitor these
    requirements. And both cases upheld the delegations on the ground that establishing a
    method of compliance with a preset requirement does not constitute modification of that
    requirement. (Sanitation Agencies, at p. 1468; Russian River, at p. 1143.)
    Turning back to the specific language of the 2014 permit, we read the plain
    language of the disputed provisions to provide a specific authorization to discharge
    0.49 mgd with authority to increase that discharge to 0.85 mgd placed in the executive
    officer. We further conclude the ability to increase the discharge limit constitutes a
    delegation of the authority to modify the permit.
    The parties have identified no case law specifically on point with respect to
    determining whether the increase in effluent discharge authorized by the executive officer
    constitutes a modification of the waste discharge requirement, and we have identified
    none in our own research. However, both sides note that the relevant provisions of
    California’s laws are meant to implement and mirror the requirements of the Clean Water
    Act and its NPDES permit process. In several cases under that federal scheme, changes
    to effluent discharge limitations, or other changes to discharge requirements in NPDES
    19.
    permits, have been rejected as improper modifications of the permit if the formal
    modification procedures of the statutory scheme have not been met. (See Proffitt v.
    Rohm & Haas (3d Cir. 1988) 
    850 F.2d 1007
    , 1012–1013 [relaxing of cadmium,
    biochemical oxygen demand, and chemical oxygen demand discharge limitations
    improper modification when amendments were not subject to public notice or hearings];
    Citizens For A Better Environment v. Union Oil Co. (9th Cir. 1996) 
    83 F.3d 1111
    , 1119–
    1120 [provisions in cease and desist order allowing time to comply with permitted
    requirements could not override permit’s specific mandates]; Ohio Valley Envtl.
    Coalition, Inc. v. Apogee Coal Co., LLC (S.D.W.Va. 2008) 
    555 F.Supp.2d 640
    , 645–646
    [compliance order removing effluent limitations to comply with longstanding agency
    practice insufficient to modify permit where formal modification requirements not met].)
    Although none of these cases expressly hold that a change to previously set discharge
    numbers constitute a modification to an NPDES permit, each implicitly rests on that
    conclusion.
    Concluding that increasing the effluent discharge limitation in this case constitutes
    a modification is also appropriate when viewing the purpose of formal hearings for
    permit modifications in the NPDES. In each of the three federal cases noted above,
    holding formal public hearings before changing the previously set discharge limitations,
    or otherwise modifying the specific terms of the permit, was deemed necessary as part of
    a broader public function of the permitting process.
    “Public notice is not merely a formality; it ensures that the public has a meaningful
    opportunity to participate in the issuance of a permit.” (Ohio Valley Environmental
    Coalition, Inc. v. Apogee Coal Co., LLC, supra, 555 F.Supp.2d at p. 646.) Such public
    proceedings “ensure that the standards embodied in an NPDES permit cannot be evaded
    with the cooperation of compliant state regulatory authorities.” (Citizens For A Better
    Environment v. Union Oil Co., 
    supra,
     83 F.3d at p. 1120.) In the present case, a public
    hearing was held where evidence was discussed supporting and opposing the proposed
    20.
    0.49-mgd limit. Although the propriety of that figure was heavily disputed, the public
    was presented with an opportunity to review the appropriateness of that figure.
    In contrast, prior to the purported amendment to 0.85 mgd, only the executive
    officer was required to see the documents submitted supporting that level of discharge.
    There was no effective way for the public to review and test the percolation rate
    calculations, the maintenance schedule, or any of the other requirements the Water
    Quality Board considered essential to increasing the permitted flow. The public was not
    informed whether or not the documents properly showed a 0.85-mgd discharge was
    viable and thus could not ensure that proper permitting requirements were not being
    evaded through the cooperation of a compliant regulatory officer.
    We conclude that a determination increasing the permissible water flow of a waste
    discharge plan constitutes a modification under section 13223. This conclusion is
    consistent with the notion in Hampson that granting an exemption to a water control plan
    or the waste discharge requirements therein would constitute a modification of that plan.
    Unlike Russian River and Sanitation Agencies, granting an increase in water discharge
    amounts is not equivalent to adopting a method of compliance with a predetermined
    permissible discharge. Such a change is much more closely aligned with the types of
    changes found to require formal modification procedures in the federal cases discussed
    above. Thus, at best, the language of the waste discharge requirements could only grant
    the executive officer the ability to review the increase request and provide a modification
    recommendation to the Water Quality Board. The trial court’s conclusion to the contrary
    was incorrect.
    We Do Not Reach the Remaining Disputes
    The parties raise several additional claims in this appeal. Malaga argues that even
    if the 2014 permit did authorize a 0.85-mgd discharge, it would not matter as the permit
    is a nullity due to several procedural flaws and alleged violations of the Administrative
    Procedure Act (Gov. Code, § 11400 et seq.). The Water Quality Board responds with
    21.
    allegations Malaga failed to exhaust its administrative remedies regarding virtually every
    issue raised and maintains there were no procedural violations. The trial court based its
    judgment upon a determination that the matter was moot because the 2014 permit granted
    Malaga a 0.85-mgd discharge at all relevant times. Because of this determination, the
    trial court did not specifically consider or rule upon any assertions regarding the
    exhaustion of administrative remedies, procedural or Administrative Procedure Act
    violations, or other related issues.
    On appeal, we review the judgment of the underlying court. In this instance, that
    judgment is the 2014 permit grants a 0.85-mgd discharge and this grant renders the action
    moot. The remaining issues raised by the parties do not relate to this judgment, but only
    arise should it be set aside and the case not be deemed moot. Accordingly, we exercise
    our discretion not to reach these issues. We remand this matter to the trial court to first
    consider whether the expiration of the 2014 permit renders this case moot and, if not, to
    resolve any remaining disputes in the first instance.
    DISPOSITION
    The Water Quality Board’s motion to dismiss is denied.
    The Water Quality Board’s request for judicial notice is granted.
    The judgment is reversed, and the matter remanded for further proceedings
    consistent with this opinion.
    Malaga is entitled to its costs on appeal.
