    Opinion of the Court
    STROUD, Judge.
    This case arises from the issuance of a National Pollutant Discharge
    Elimination System Permit (“Permit”) by respondent North Carolina Department of
    Environmental Quality, Division of Water Resources (“DEQ”) to respondent-
    intervenor Martin Marietta Materials, Inc., (“Martin Marietta”) allowing respondent
    Martin Marietta to discharge wastewater from Vanceboro Quarry (“quarry”) into
    “unnamed tributaries to Blounts Creek[.]” The Administrative Law Judge (“ALJ”) of
    the Office of Administrative Hearings (“OAH”) entered a final decision affirming the
    issuance of the Permit. Petitioners Sound Rivers, Inc. and North Carolina Coastal
    Federation, Inc. (“Petitioners”) filed a petition for judicial review with the superior
    court.1 The superior court reversed the ALJ’s final decision based upon a failure to
    “ensure reasonable compliance with the biological integrity standard” (“biological
    integrity standard”) found in the North Carolina Administrative Code (“Code”) but
    concluded that the Permit was in compliance with other water quality standards,
    including “swamp waters supplemental classification and the state antidegradation
    rule” (“swamp waters”) and pH (“pH standards”).
    1 Petitioner Sound Rivers, Inc. was known as the Pamlico-Tar River Foundation when the original
    petition for a contested case hearing was filed; it noted its name had changed to Sound Rivers, Inc.
    effective 1 April 2015 in its 20 April 2015 petition for judicial review. For simplicity, we will refer to
    the petitioner throughout this opinion as Sound Rivers.

    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Respondent Martin Marietta and respondent DEQ appeal from the superior
    court’s order reversing the ALJ’s order due to its conclusion on biological integrity
    standards. Petitioners cross-appeal from the superior court’s order based upon its
    conclusion that the Permit reasonably ensured compliance with water quality
    standards regarding swamp waters and pH standards. We note at the outset that at
    all stages of the proceedings, the parties have filed numerous documents, including
    briefs, motions, proposed drafts of orders, responses, and exhibits; in this opinion we
    will mention only those documents relevant to the issue on appeal as the documents
    are so voluminous, but we have reviewed all of the documents before us and after
    review of the briefs, record, and transcripts, we affirm the superior court’s order as to
    swamp waters and pH standards and reverse as to the biological integrity standard.
    I.     Factual and Procedural Background
    In September of 2013, Sound Rivers and North Carolina Coastal Federation
    filed a petition for a contested case hearing on DEQ’s issuance of the Permit on 24
    July 2013 to Martin Marietta. According to the petition, the Permit authorized
    Martin Marietta to “the discharge of 12 million gallons of mine wastewater into
    tributaries of Blounts Creek each day.”       Petitioners alleged the Permit violated
    “applicable laws” attached and incorporated into the petition.
    The Permit was issued under the provisions of North Carolina General Statute
    § 143-215.1 and “other lawful standards and regulations promulgated and adopted
    -3-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    by the North Carolina Environmental Management Commission, and the Federal
    Water Pollution Control Act, as amended[.]” The Permit was effective on 1 September
    2013 and would expire on 31 August 2018.2 The Permit allowed Martin Marietta to
    discharge water pumped from its quarry “from two pit clarification ponds” identified
    on an attached map into “receiving waters designated as unnamed tributaries to
    Blounts Creek in the Tar-Pamlico River Basin in accordance with effluent limitations,
    monitoring requirements, and other conditions set forth in Parts I, II, and III” of the
    Permit.     The supplement to the Permit cover sheet noted that the “unnamed
    tributary” into which the wastewater would be discharged was “classified as C-
    Swamp NSW waters in the Tar-Pamlico River Basin.” In this opinion, we will refer
    to the waters into which wastewater from the quarry would be discharged as “Blounts
    Creek.”
    In September of 2013, respondent DEQ submitted a prehearing statement
    identifying the issues to be resolved as
    2 No party has argued this case may be moot based upon the fact that the Permit as issued would have
    expired in 2018. “A case is ‘moot’ when a determination is sought on a matter which, when rendered,
    cannot have any practical effect on the existing controversy. Thus, the case at bar is moot if an
    intervening event had the effect of leaving plaintiff with no available remedy. A moot claim is not
    justiciable, and a trial court does not have subject matter jurisdiction over a non-justiciable claim.
    Moreover, if the issues before the court become moot at any time during the course of the proceedings,
    the usual response is to dismiss the action for lack of subject matter jurisdiction.” Cumberland Cnty.

    expiration, and (2) there is a reasonable expectation that the same complaining party would be
    subjected to the same action again.” (citations, quotation marks, and brackets omitted)).

    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    [(1)] whether Respondent, properly issued the Permit
    pursuant to Article 21, Chapter 143 of the North Carolina
    General Statutes and the applicable rules promulgated
    thereunder, including but not limited to 15A NCAC
    2B.0200 et. seq.; and [(2)] whether Respondent, in issuing
    the Permit substantially prejudiced Petitioner’s rights and
    erred in one or more of the five ways enumerated in N.C.
    Gen. Stat. § 150B-23(a).
    Martin Marietta, who had intervened, also submitted a prehearing statement
    contending the Permit “would not violate water quality standards” and noted that
    the Permit had been issued “after years of pre-permitting work, the submission of
    engineering, economic, and ecological studies and materials by Martin Marietta, and
    extensive review and analysis by DWR [, Division of Water Resources,] and other
    state and federal government agencies.” Martin Marietta contended state and federal
    regulatory personnel had thoroughly analyzed the proposed permit over about
    eighteen months, including “site visits, field work, numerous communications and
    meetings, the further submission of materials and studies by Martin Marietta, and
    public comment and a public hearing, in which Petitioners and their members and
    counsel participated.” Thus, Martin Marietta contended state and federal regulatory
    personnel had already considered the “claims asserted by Petitioners in this contested
    case” and DEQ “correctly concluded that the proposed discharge allowed by the NPDS
    Permit would not violate water quality standards and lawfully and appropriately
    issued the NPDES Permit.”
    On 6 November 2013, Petitioners filed their prehearing statement contending
    -5-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    that the Permit did not comply with biological integrity standards, protection of
    swamp waters, and pH standards, and identifying the issues as:
    1.     The Clean Water Act and state laws implementing
    it prohibit discharges that violate any water quality
    standard. State water quality standards for waters
    like Blounts Creek prohibit any discharge that will
    make a waterbody unsuitable for native plants and
    animals, violating its “biological integrity.” Martin
    Marietta’s proposed discharge of 12 million gallons
    of mine wastewater per day into Blounts Creek
    would displace native fish, macroinvertebrates
    (insects, mollusks, crayfish, etc.) and plants. Did
    DWR exceed its authority, act erroneously, fail to
    use proper procedure, act arbitrarily or capriciously
    or fail to act as required by rule or law “err”) by
    authorizing the discharge?
    2.     The Clean Water Act and state laws implementing
    it prohibit discharges that violate any water quality
    standard. The state water quality standard for pH
    is the normal pH for the waterbody receiving a
    discharge, which is between 4.0 and 5.5 in Blounts
    Creek. Did DWR err by authorizing a discharge that
    would raise the pH in the creek to a minimum of 6.3
    to 6.9?
    3.     The Clean Water Act and state laws implementing
    it require classification of waters to protect existing
    uses. North Carolina has classified Blounts Creek
    as swamp waters to protect characteristics unique to
    these waters, including low flow and velocity, low
    pH, and high tannin levels. Did DWR err by issuing
    a permit for a discharge that will cause Blounts
    Creek to have higher flow and velocity, near neutral
    pH, and low tannin levels, thereby no longer
    qualifying as swamp waters?
    In November of 2014 Petitioners filed a motion for summary judgment on the
    -6-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    issues of whether Petitioners were “persons aggrieved” under North Carolina’s
    Administrative Procedure Act and whether DWR had exceeded its authority or failed
    to act as required by law based upon failure to ensure compliance with the biological
    integrity water quality standard, the pH water quality standard, and Blounts Creek’s
    swamp waters classification.      Petitioners also submitted numerous affidavits to
    support their motion. On 25 November 2014, Martin Marietta filed a motion for
    summary judgment.
    On 23 March 2015, the ALJ entered an order granting summary judgment for
    respondents.     The order stated at length the undisputed facts and concluded
    “Petitioners are not ‘Persons Aggrieved[;]’” “Respondent’s Decision to Issue the
    Permit was Not in Violation of N.C. Gen. Stat. § 150B-23(a)[;]” “Respondent Ensured
    Compliance with Biological Integrity Standard[;]” “Respondent Ensured Compliance
    with pH Water Quality Standards[;]” and “Respondent Protected Existing Uses[.]”
    The ALJ also noted the “Re-opener Provision” of the Permit:
    The permit issued to the Respondent-Intervenor
    allows the Respondent to re-open and modify the permit if
    water quality standards are threatened or other monitored
    data cause concern. Even if Petitioner provided evidence
    of specific and particularized potential violations of water
    quality standards, the re-opener provision assures
    reasonable compliance with those standards.
    In summary, the ALJ concluded,
    There is no evidence that Petitioners’ rights have
    been substantially prejudiced, or that Respondent
    -7-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    exceeded its authority or jurisdiction, acted erroneously,
    failed to use proper procedure, acted arbitrarily or
    capriciously, or failed to act as required by law or rule.
    For the reasons discussed herein, there is no genuine
    issue as to any material fact. Respondent’s Motion for
    Summary Judgment is allowed; Respondent-Intervenor’s
    Motion for Summary Judgment is allowed. Petitioners’
    Motion for Summary Judgment is denied, and Petitioners
    are not entitled to the relief requested in the petition.
    On 20 April 2015, Petitioners filed a petition for judicial review of the summary
    judgment order contesting the ALJ’s determinations.         On 20 May 2015, Martin
    Marietta responded to and filed a motion to dismiss petitioners’ petition for judicial
    review, arguing the superior court did not have subject matter jurisdiction because
    petitioners are not “persons aggrieved” and therefore not entitled to judicial review.
    On 13 November 2015, the superior court entered its order denying Martin Marietta’s
    motion to dismiss and denying petitioner’s petition on all grounds except for the issue
    of “persons aggrieved.”    The superior court concluded petitioners were persons
    aggrieved and remanded the matter back to OAH for a “full plenary hearing[.]”
    After a “hearing on the merits May 31, 2016 through June 9, 2016[,]” on 30
    November 2016, the ALJ issued a 62-page final decision. The final decision addressed
    four primary issues:
    Issue 1: “pH Claim”: Whether Petitioners have met their
    burden of proving that Respondent exceeded its authority
    or jurisdiction, acted erroneously, failed to use proper
    procedure, acted arbitrarily or capriciously, or failed to act
    as required by law or rule in determining the NPDES
    -8-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Permit reasonably ensures compliance with the pH water
    quality standard.
    Issue 2: “Swamp Waters Claim”: Whether Petitioners
    have met their burden of proving that Respondent
    exceeded its authority or jurisdiction, acted erroneously,
    failed to use proper procedure, acted arbitrarily or
    capriciously, or failed to act as required by law or rule in
    determining the NPDES Permit reasonably ensures
    compliance with water quality standards and regulations
    related to      the “Swamp Waters” supplemental
    classification.
    Issue 3:     “Biological Integrity Claim”: Whether
    Petitioners have met their burden proving that Respondent
    exceeded its authority or jurisdiction, acted erroneously,
    failed to use proper procedure, acted arbitrarily or
    capriciously, or failed to act as required by law or rule in
    determining the NPDES Permit reasonably ensures
    compliance with the biological integrity water quality
    standard.
    Issue 4: Substantial Prejudice: Whether Petitioners
    have met have their burden of proving that Respondent
    substantially prejudiced Petitioners’ rights in issuing the
    NPDES Permit.
    The ALJ made 311 findings of fact; we will address some of these findings of
    fact below in detail in our discussion of the challenged findings applicable to each
    issue. The order ultimately denied Petitioners’ claims based upon two alternative
    and independent grounds: First, “Petitioners failed to meet their burden of proving
    by a preponderance of evidence that Respondent DWR exceeded its authority or
    jurisdiction, acted erroneously, acted arbitrarily and capriciously, used improper
    procedure, or failed to act as required by law or rule in issuing the NPDES Permit.”
    -9-
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Second, as an independent and alternative basis for the ruling, “Petitioners failed to
    carry their burden of proof by a preponderance of the evidence that their rights have
    been substantially prejudiced by Respondent DWR’s issuance of the NPDES Permit.”
    In December of 2016, Petitioners filed a petition in superior court for judicial
    review of the ALJ’s final decision. Petitioners alleged the order was in error in that
    “The Final Decision Contains Findings of Fact Unsupported by Substantial Evidence,
    Findings That Are Arbitrary, Capricious, or an Abuse Of Discretion, and Findings
    Affected By Other Errors Of Law[;]” “The ALJ’s Conclusion That Petitioners Are Not
    Substantially Prejudiced Is Erroneous[;]” “The ALJ’s Grant of Deference to DWR
    Staff And [Martin Marietta] Consultants Is An Error Of Law[;]” “The ALJ’s
    Conclusion That DWR Complied with the Biological Integrity Standard Is
    Erroneous[;]” “The ALJ’s Conclusion That DWR Complied with the pH Standard Is
    Erroneous[;]” “The ALJ’s Conclusions of Law Regarding the Swamp Waters
    Classification And Antidegradation Rules Are Erroneous[;]” and “The ALJ’s
    Conclusion That the Required Reopener Provision Ensures Compliance With Water
    Quality Standards Is Erroneous[.]”
    On 30 January 2017, Martin Marietta filed a motion to dismiss the petition
    under North Carolina General Statute § 150B-46 and North Carolina Rule of Civil
    Procedure 12 because the petition for judicial review was not timely served. On 30
    October 2017, the superior court denied Martin Marietta’s motion to dismiss. On 4
    - 10 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    December 2017, the superior court denied Martin Marietta’s motion to dismiss for
    failure to state a claim under North Carolina Rule of Civil Procedure 12(b)(6).
    On 20 December 2017, the superior court entered its order on petition for
    judicial review. The superior court noted these issues:
    I.       Did the ALJ err in admitting, considering, or
    determining the credibility or weight of evidence?
    II.      Did the ALJ err in upholding DWR’s issuance of the
    Permit as reasonably ensuring compliance with:
    A.     The      swamp      waters      supplemental
    classification and antidegradation rule;
    B.     The water quality standard for pH; and
    C.     The water quality standard for biological
    integrity?
    III.     Did the ALJ err in holding that the Permit’s
    monitoring and reopener provisions further
    reasonably ensure compliance with state water
    quality standards?
    IV.      Did the ALJ err in holding that Petitioners failed to
    prove their rights were substantially prejudiced?
    The superior court entered its order in paragraph form with no numbered findings of
    fact and with two conclusions of law.        Ultimately, the superior court concluded
    Petitioners were “substantially prejudiced by the issuance of the Permit and are
    entitled to the relief sought.” On the substantive issues regarding water quality
    standards, the superior court concluded that DEQ “did not ensure reasonable
    compliance with the biological integrity standard as set forth in 15A N.C.A.C. 02B
    - 11 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    .211(2), 0220(2), and 0202(11)” and therefore reversed the final decision of the ALJ
    and vacated the Permit.
    Over the course of 10 days, all parties filed written notices of appeal and cross-
    appeal, seeking review of the following orders:
    1.    13 November 2015 order granting summary judgment to Petitioners regarding
    being “persons aggrieved” and denying all other matters;
    2.    27 February 2017 ruling from the superior court denying Martin Marietta’s
    motion to dismiss and granting Petitioners’ motion for extension of time;
    3.    30 October 2017 order memorializing 27 February 2017 ruling that denied
    Martin Marietta’s motion to dismiss and granted Petitioners’ motion for
    extension of time;
    4.    4 December 2017 order denying Martin Marietta’s motion to dismiss, and
    5.    20 December 2017 superior court order on the petition for judicial review
    vacating the Permit.
    II.     Preliminary Issues
    We begin our analysis by addressing preliminary issues.
    A.    Martin Marietta’s Motion to Dismiss
    On 30 January 2017, Martin Marietta filed a motion to dismiss the petition for
    judicial review under North Carolina General Statute § 150B-46 and North Carolina
    Rule of Civil Procedure 12 because it was not timely served on Martin Marietta. On
    30 October 2017, the superior court denied Martin Marietta’s motion to dismiss.
    North Carolina General Statute § 150B-46 (2017) provides, “Within 10 days after the
    petition is filed with the court, the party seeking the review shall serve copies of the
    - 12 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    petition by personal service or by certified mail upon all who were parties of record to
    the administrative proceedings.” According to the motion, the petition was filed on
    28 December 2016, but Martin Marietta was not actually served until 17 January
    2017. On 30 October 2017, the superior court denied Martin Marietta’s motion to
    dismiss and extended the time for service.
    Martin Marietta relies upon In re State ex rel. Employment Security
    Commission, 
    234 N.C. 651
    , 
    68 S.E.2d 311
     (1951), arguing Petitioner’s appeal must be
    dismissed due to late service of the notice:
    There is no inherent or inalienable right of appeal from an
    inferior court to a Superior Court or from a Superior Court
    to the Supreme Court.
    A fortiori, no appeal lies from an order or decision of
    an administrative agency of the State or from the
    judgments of special statutory tribunals whose proceedings
    are not according to the course of the common law, unless
    the right is granted by statute. If the right exists, it is
    brought into being, and is a right granted, by legislative
    enactment.
    There can be no appeal from the decision of an
    administrative agency except pursuant to specific
    statutory provision therefor.
    Obviously then, the appeal must conform to the
    statute granting the right and regulating the procedure.
    The statutory requirements are mandatory and not
    directory. They are conditions precedent to obtaining a
    review by the courts and must be observed. Noncompliance
    therewith requires dismissal.
    ....
    This statement of the grounds of the appeal must be
    filed within the time allowed for appeal. Its purpose is to
    give notice to the Commission and adverse parties of the
    alleged errors committed by the Commission and limit the
    - 13 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    scope of the hearing in the Superior Court to the specific
    questions of law raised by the errors assigned. Clearly it
    was intended, and must be construed, as a condition
    precedent to the right of appeal. Noncompliance therewith
    is fatal.
    Id. at 653-54, 68 S.E.2d at 312 (emphasis added). Although the petition for judicial
    review was timely filed, Martin Marietta contends because Petitioners failed to serve
    the notice of appeal upon Martin Marietta within 10 days under North Carolina
    General Statute § 150B-46, the superior court never obtained subject matter
    jurisdiction. The superior court thus had no jurisdiction to extend the time for
    service, so Martin Marietta’s motion to dismiss should have been allowed for lack of
    subject matter jurisdiction.
    We review a motion to dismiss for lack of subject matter jurisdiction de novo.
    See Hardy ex rel. Hardy v. Beaufort Cty. Bd. of Educ., 
    200 N.C. App. 403
    , 408, 
    683 S.E.2d 774
    , 778 (2009) (“Subject matter jurisdiction is a prerequisite for the exercise
    of judicial authority over any case or controversy. The standard of review on a motion
    to dismiss under Rule 12(b)(1) for lack of subject matter jurisdiction is de novo.
    (citation omitted)). While the file stamp is not legible on the petition for judicial
    review, Martin Marietta concedes that the petition was filed with the superior court
    on 28 December 2016, and thus within the time period established by North Carolina
    General Statute § 150B-45 to invoke jurisdiction from the final decision entered on
    - 14 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    30 November 2016. See N.C. Gen. Stat. § 150B-45 (2017)3 (“To obtain judicial review
    of a final decision under this Article, the person seeking review must file a petition
    within 30 days after the person is served with a written copy of the decision.”). In NC
    Department of Public Safety v. Owens, this Court held “that the superior court has
    the authority to grant an extension in time, for good cause shown, to a party to serve
    the petition beyond the ten days provided for under G.S. 150B–46.” 
    245 N.C. App. 230
    , 234, 
    782 S.E.2d 337
    , 340 (2016). Under Owens, the superior court had subject
    matter jurisdiction and properly extended the time for service and thus denied the
    motion to dismiss. See 
    id.
     Because Martin Marietta raises only the issue of subject
    matter jurisdiction in its brief, and not the substance of the good cause shown, we end
    our analysis here. This argument is overruled.
    B.     Standing of Petitioners as “Persons Aggrieved”
    Martin Marietta next contends that the superior court erred in determining
    that petitioners were substantially prejudiced by DEQ’s issuance of the Permit.
    At the outset, we must determine our standard of
    review. That standard of review will depend upon the
    nature of the error alleged in the petition for judicial
    review. If errors of law are alleged, our review is de novo.
    If the alleged error is that the final agency decision is not
    supported by the evidence, we employ the whole record
    test.

    paying a fee in an amount established in G.S. 150B-23.2
    and by filing a petition with the Office of Administrative
    Hearings and, except as provided in Article 3A of this
    Chapter, shall be conducted by that Office. The party who
    files the petition shall serve a copy of the petition on all
    other parties and, if the dispute concerns a license, the
    person who holds the license. A party who files a petition
    shall file a certificate of service together with the petition.
    A petition shall be signed by a party, an attorney
    representing a party, or other representative of the party
    as may specifically be authorized by law, and, if filed by a
    party other than an agency, shall state facts tending to
    establish that the agency named as the respondent has
    deprived the petitioner of property, has ordered the
    petitioner to pay a fine or civil penalty, or has otherwise
    substantially prejudiced the petitioner’s rights and that the
    agency:
    (1)     Exceeded its authority or jurisdiction;
    (2)     Acted erroneously;
    (3)     Failed to use proper procedure;
    (4)     Acted arbitrarily or capriciously; or
    (5)     Failed to act as required by law or rule.
    The parties in a contested case shall be given an
    opportunity for a hearing without undue delay. Any person
    aggrieved may commence a contested case hereunder.
    N.C. Gen. Stat. § 150B-23(a) (2013) (emphasis added).4 Petitioners have not alleged
    they were deprived of property or were ordered to pay a fine or civil penalty, and thus
    they must show substantial prejudice. See id. North Carolina General Statute §
    4 Subsection(f) was amended in 2018.   See N.C. Gen. Stat. § 150B-23 (2018).

    establish the facts required by G.S. 150B-23(a) by a preponderance of the evidence.”
    N.C. Gen. Stat. § 150B-29 (2013). Thus, in this case, petitioners had to establish
    substantial prejudice by a preponderance of the evidence. See N.C. Gen. Stat. §§
    150B-23, -29.
    In Empire Power Co. v. North Carolina Department of Environmental Health
    and Natural Resources, our Supreme Court discussed the meaning of the term
    “person aggrieved” in a case with a similar context, arising from issuance of a draft
    air quality permit for a proposed turbine electric generating station. 
    337 N.C. 569
    ,
    572, 
    447 S.E.2d 768
    , 770 (1994). As explained in Empire Power Co.,
    Under the NCAPA, any “person aggrieved” within
    the meaning of the organic statute is entitled to an
    administrative hearing to determine the person’s rights,
    duties, or privileges. N.C.G.S. § 150B–23(a). “‘Person
    aggrieved’ means any person or group of persons of
    common interest directly or indirectly affected
    substantially in his or its person, property, or employment,
    by an administrative decision.” N.C.G.S. § 150B–2(6).
    Under the predecessor judicial review statute, which did
    not define the term, the Court gave it an expansive
    interpretation:
    The expression “person aggrieved” has
    no technical meaning. What it means depends
    on the circumstances involved. It has been
    variously defined: “Adversely or injuriously
    affected; damnified, having a grievance,
    having suffered a loss or injury, or injured;
    also having cause for complaint.           More
    specifically the word(s) may be employed
    meaning adversely affected in respect of legal
    - 17 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    rights, or suffering from an infringement or
    denial of legal rights.”
    In re Assessment of Sales Tax, 259 N.C. at 595, 131 S.E.2d
    at 446 (quoting 3 C.J.S. Aggrieved, at 509 (1973)). For the
    following reasons, we conclude that Clark is a “person
    aggrieved” as defined by the NCAPA within the meaning
    of the organic statute.
    Clark alleged that DEHNR issued the permit
    allowing construction and operation of air emission sources
    at the LCTS in violation of its statutory and regulatory
    duties: to act on all permit applications “so as to effectuate
    the [legislative] purpose . . . by reducing existing air
    pollution and preventing, so far as reasonably possible, any
    increased pollution of the air from any additional or
    enlarged sources,” N.C.G.S. § 143–215.108(b); to reduce
    levels of ozone pollution in the Mecklenburg County area;
    to assess fully the impact of emissions of air pollutants
    from the LCTS on levels of ozone pollution in Mecklenburg
    County; to assess fully the impact of sulfur dioxide
    emissions from the LCTS; to require air pollution control
    technology adequate to control the emission of potentially
    harmful pollutants from the LCTS; and to require Duke
    Power to cause air quality offsets. Clark also alleged that
    DEHNR issued the permit in violation of its statutory duty
    to adequately address comments filed by Clark and other
    members of the public during the public comment period.
    Clark further alleged that, as the owner of property
    immediately adjacent to and downwind of the site of the
    proposed LCTS—which will emit tons of harmful air
    pollutants if constructed and operated in accordance with
    its air quality permit—he and his family will suffer injury
    to their health, the value of their property, and the quality
    of life in their home and their community.
    In enacting the air pollution control provisions, the
    General Assembly, as noted above, declared its intent
    to achieve and to maintain for the citizens of
    the State a total environment of superior
    quality. Recognizing that the water and air
    resources of the State belong to the people, the
    General Assembly affirm[ed] the State’s
    - 18 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    ultimate responsibility for the preservation
    and development of these resources in the
    best interest of all its citizens and declare[d]
    the prudent utilization of these resources to
    be essential to the general welfare.
    N.C.G.S. § 143-211. To further that intent, the General
    Assembly mandated that standards of water and air purity
    be designed, and programs implemented to achieve those
    standards,
    to protect human health, to prevent injury to
    plant and animal life, to prevent damage to
    public and private property, to insure the
    continued enjoyment of the natural
    attractions of the State, to encourage the
    expansion of employment opportunities, to
    provide a permanent foundation for healthy
    industrial development and to secure for the
    people of North Carolina, now and in the
    future, the beneficial uses of these great
    natural resources.
    Id. (emphasis added).
    Clearly, Clark alleged sufficient injury in fact to
    interests within the zone of those to be protected and
    regulated by the statute, and rules and standards
    promulgated pursuant thereto, the substantive and
    procedural requirements of which he asserts the agency
    violated when it issued the permit. As an adjacent property
    owner downwind of the LCTS, Clark may be expected to
    suffer from whatever adverse environmental consequences
    the LCTS might have. In addition, a judgment in favor of
    Clark would substantially eliminate or redress the injury
    likely to be caused by the decision to permit Duke Power to
    build the LCTS. Clark therefore is a “person aggrieved”
    within the meaning and intent of the air pollution control
    act. See Orange County v. Dept. of Transportation, 
    46 N.C. App. 350
    , 360–62,

    plaintiffs would be affected as taxpayers; further, the
    “procedural injury” implicit in the failure of an agency to
    prepare an environmental impact statement was itself a
    sufficient “injury in fact” to support standing as an
    “aggrieved party” under former N.C.G.S. § 150A–43, as

    to the corporation, so that the right of petitioner to be heard
    was impaired; petitioner therefore qualified as an
    “aggrieved person” for purposes of judicial review; further,
    petitioner alleged that its property rights in the river were
    affected, and these allegations also established petitioner's
    “aggrieved person” status); see generally 2 Am. Jur. 2d

    Id. at 588-90, 
    447 S.E.2d at 779-81
     (alterations in original) (emphasis added).
    Here, similar to Empire Power Co. and the cases quoted within Empire,
    Petitioners alleged substantial prejudice in that the Permit was issued without
    compliance with applicable regulations in that Martin Marietta’s “proposed discharge
    of 12 million gallons of mine wastewater per day into Blounts Creek would displace
    - 20 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    native fish, macroinvertebrates (insects, mollusks, crayfish, etc.) and plants[,]” and
    the wastewater would cause “higher flow and velocity, near neutral pH, and low
    tannin levels” meaning Blounts Creek would no longer qualify as swamp waters. See
    generally 
    id.
    More specifically, one of the individuals who filed an affidavit in support of
    Petitioners, Mr. Jimmy Daniels, averred that he was a member of the Pamlico-Tar
    River Foundation and both his “home and business, [“Cotton Patch Landing, a boat
    ramp and marina,”] are right on the banks of Blounts Creek.” Mr. Daniels described
    in detail the biodiversity in Blounts Creek and how it draws people “from all across
    the state[.]” Mr. Daniels averred that he boated “a couple of times a week” and
    enjoyed the wildlife diversity; through Cotton Patch Landing, he sells fishing
    supplies, stores and maintains boats, and engages in commercial activities involving
    his boat ramp. Mr. Daniels also noted the hundreds of thousands of dollars he has
    invested into his business and stated that based on his experience with Blounts
    Creek, he believed Martin Marietta’s wastewater being dumped “into the
    headwaters” “will change the way the whole system works.” Mr. Daniels explained
    specifically why and how the wastewater would affect his business and personal
    interests and noted “word of mouth concerning the discharge” had already had a
    negative effect on Cotton Patch Landing when a fishing tournament previously held
    at Cotton Patch Landing was moved due to fears over how the wastewater would
    - 21 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    impact fishing for the tournament. Mr. Daniels noted Cotton Patch Landing lost
    approximately $5,000 from the tournament move. Again, Mr. Daniels is but one of
    many affiants noting similar issues with the wastewater being dumped into Blounts
    Creek. We view the interests of Mr. Daniels and other affiants about wastewater in
    Blounts Creek to be similar to the complainant in Empire Power Co., who alleged,
    as the owner of property immediately adjacent to and
    downwind of the site of the proposed LCTS—which will
    emit tons of harmful air pollutants if constructed and
    operated in accordance with its air quality permit—he and
    his family will suffer injury to their health, the value of
    their property, and the quality of life in their home and
    their community.
    
    Id. at 589
    , 
    447 S.E.2d at 780
    .
    While Martin Marietta contends that Petitioner’s alleged prejudice amounts
    only to speculation as to the effects of the discharge of water allowed by the Permit,
    allegations as to potential prejudice here are no different from the allegations of
    potential air pollution in Empire Power Co., as the actual effects cannot be known for
    certain until the discharge occurs. See generally 
    id.,
     
    337 N.C. 569
    , 
    447 S.E.2d 768
    .
    In addition, this Court has clarified that in a challenge based upon an alleged failure
    of an agency or department of the State to follow its own guidelines, the prejudice
    standard differs from that in other types of civil cases. See, e.g., N.C. Forestry Ass’n
    v. N.C. Dep’t of Env’t & Natural Res., Div. of Water Quality, 
    357 N.C. 640
    , 644, 
    588 S.E.2d 880
    , 882–83 (2003) (“In general, individuals adversely affected by a
    - 22 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    discretionary agency decision generally have standing to complain that the agency
    based its decision upon an improper legal ground.” (citation and quotation marks
    omitted)). Otherwise the burden of showing substantial prejudice would be “nearly
    impossible”:
    Because the substance of those policies required the
    Department to consider a number of discretionary factors,
    however, we pointed out that a showing of prejudice would
    be “nearly impossible” for the petitioner to achieve.
    Specifically, we observed that
    to show prejudice from failure to follow policy,
    the petitioner would have to show, not only
    how he stood in relation to other employees in
    the same class as to type of appointment,
    length of service, and work performance, but
    he would have to show the weight which the
    Department would attribute to each of those
    factors. The Commission and the reviewing
    court would be relegated to speculating how
    the Department would weigh each factor.
    Therefore, we held that it was sufficient to show prejudice
    for the petitioner to establish that the Department failed
    to follow the mandatory policies of the Commission, which
    had been promulgated pursuant to statutory authority. A
    separate showing of prejudice was unnecessary in that
    circumstance.
    Surgical Care Affiliates, LLC v. N.C. Dep’t of Health & Human Servs.,

    , 627, 
    762 S.E.2d 468
    , 473 (2014) (citations and brackets omitted).
    Here, Petitioners alleged that the Division of Water Resources violated its own
    applicable regulations by issuing the Permit to Martin Marietta which authorized
    “the discharge of 12 million gallons of mine wastewater into tributaries of Blounts
    - 23 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Creek each day.” Petitioners have alleged DEQ failed to follow its own policies in
    issuing the Permit and that the discharge of wastewater into Blounts Creek, if done
    in a manner not in compliance with the applicable regulations, would damage the
    water quality, the fish and other biota in Blounts Creek, and the personal and
    commercial benefits derived from Blounts Creek. Petitioners are “within the zone of
    those to be protected and regulated by the statute, and rules and standards
    promulgated pursuant thereto, the substantive and procedural requirements of
    which he asserts the agency violated when it issued the permit.” Empire Power Co.,
    
    337 N.C. at 589
    , 
    447 S.E.2d at 780
    . The superior court did not err in concluding
    Petitioners demonstrated their rights were substantially prejudiced and thus they
    are “person[s] aggrieved[.]”          
    Id. at 590
    , 
    447 S.E.2d at 780
    .               This argument is
    overruled.5
    5 Implicit in this holding is also a rejection of Martin Marietta’s argument that “North Carolina courts
    have held that only the state, and not individual plaintiffs, can enforce public trust rights” such as
    interests in fishing, boating, and recreation. As DEQ acknowledges, the cases Martin Marietta cites
    for this proposition are inapposite. This is not a claim under public trust doctrine or any other common
    law action, see Town of Nags Head v. Cherry, Inc., 
    219 N.C. App. 66
    , 
    723 S.E.2d 156
     (2012); Fish House,
    Inc. v. Clarke, 
    204 N.C. App. 130
     (2010), but instead a request for review of an agency action pursuant
    to the North Carolina Administrative Procedure Act. In such an action, the organic statute at issue
    defines the rights, duties, and privileges that provide the grounds for the administrative hearing.
    Empire Power Co., 
    337 N.C. at 583
    , 
    447 S.E.2d at 583
    . North Carolina’s water quality statutes and
    associated rules specifically protect water quality for recreational uses. See, e.g., 
    N.C. Gen. Stat. § 143-214.1
    (3) (year) (directing adoption of water quality standards and classifications that consider the
    use and value of waters of the state for “recreation”); 15A NCAC 02b.0101(c)(1) (stating Class C are
    freshwaters protected for “secondary recreation” and “fishing”). Petitioners “interests in the waters
    affected” by the discharge at issue “are discrete and particular to [its] certain members who live near,
    or who visit, fish, or shellfish in the affected waters, and are not merely a generalized public interest.”

    Opinion of the Court
    III.   Substantive Issues regarding Permit
    We now turn to the substantive issues regarding issuance of the Permit.
    A.       Standard of Review
    Petitioners raised three arguments regarding DEQ’s failure to ensure
    compliance with applicable water quality standards. The superior court determined
    that the ALJ’s order was in error only as to the findings and conclusion regarding
    that DEQ ensured “reasonable compliance with the biological integrity standard as
    set forth in 15A N.C.A.C. 02B .211(2), 0220(2), and 0202(11)[,]” and DEQ and Martin
    Marietta appeal this determination. The superior court affirmed the ALJ’s findings
    and conclusions regarding the other standards – swamp waters and pH standards–
    and Petitioners cross-appealed these determinations. We will therefore address the
    arguments as to each substantive issue in the order as addressed by the superior
    court.
    The North Carolina Administrative Procedure Act
    (APA), codified at Chapter 150B of the General Statutes,
    governs trial and appellate court review of administrative
    agency decisions. The APA provides a party aggrieved by
    a final decision in a contested case a right to judicial review
    by the superior court. N.C. Gen. Stat. §§ 150B–43 and –50
    (2017). A party to the review proceeding in superior court
    may then appeal from the superior court’s final judgment
    to the appellate division. N.C. Gen. Stat. § 150B–52 (2017).
    The APA sets forth the scope and standard of review for
    each court.

    ,
    - 25 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    677 (2018).
    When a superior court exercises judicial review over
    an agency’s final decision, it acts in the capacity of an
    appellate court. The APA limits the scope of the superior
    court’s judicial review as follows:
    (b)    The court reviewing a final decision may
    affirm the decision or remand the case for further
    proceedings. It may also reverse or modify the
    decision if the substantial rights of the petitioners
    may have been prejudiced because the findings,
    inferences, conclusions, or decisions are:
    (1)    In     violation     of    constitutional
    provisions;
    (2)    In excess of the statutory authority or
    jurisdiction of the agency or administrative
    law judge;
    (3)    Made upon unlawful procedure;
    (4)    Affected by other error of law;
    (5)    Unsupported by substantial evidence
    admissible under G.S. 150B-29(a), 150B-30,
    or 150B-31 in view of the entire record as
    submitted; or
    (6)    Arbitrary, capricious, or an abuse of
    discretion.
    N.C. Gen. Stat. § 150B-51 (2017). The superior court’s
    standard of review is dictated by the nature of the errors
    asserted. The APA sets forth the standard of review to be
    applied by the superior court as follows.
    (c)    In reviewing a final decision in a contested
    case, the court shall determine whether the
    petitioner is entitled to the relief sought in the
    petition based upon its review of the final decision
    and the official record. With regard to asserted
    errors pursuant to subdivisions (1) through (4) of
    subsection (b) of this section, the court shall conduct
    its review of the final decision using the de novo
    standard of review. With regard to asserted errors
    pursuant to subdivisions (5) and (6) of subsection (b)
    of this section, the court shall conduct its review of
    - 26 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    the final decision using the whole record standard of
    review.
    N.C. Gen. Stat. § 150B–51(c).
    Id. at 595-96, 813 S.E.2d at 677–78 (citations, quotation marks, and brackets
    omitted).
    Our Supreme Court has observed that the first four
    grounds enumerated under this section may be
    characterized as law-based inquiries, whereas the final two
    grounds may be characterized as fact-based inquiries.
    Moreover, it is well settled that in cases appealed from
    administrative tribunals, questions of law receive de novo
    review, whereas fact-intensive issues such as the
    sufficiency of the evidence to support an ALJ’s decision are
    reviewed under the whole record test.
    Under the de novo standard of review, the Court
    considers the matter anew and freely substitutes its own
    judgment. However, our Supreme Court has made clear
    that even under our de novo standard, a court reviewing a
    question of law in a contested case is without authority to
    make new findings of fact. Under the whole record test,
    the reviewing court may not substitute its judgment for the
    ALJ’s as between two conflicting views, even though it
    could reasonably have reached a different result had it
    reviewed the matter de novo. Instead, we must examine
    all the record evidence—that which detracts from the ALJ’s
    findings and conclusions as well as that which tends to
    support them—to determine whether there is substantial
    evidence to justify the ALJ’s decision.         Substantial
    evidence is relevant evidence a reasonable mind might
    accept as adequate to support a conclusion. We undertake
    this review with a high degree of deference because it is
    well established that
    in an administrative proceeding, it is the
    prerogative and duty of the ALJ, once all the
    evidence has been presented and considered,
    to determine the weight and sufficiency of the
    evidence and the credibility of the witnesses,
    - 27 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    to draw inferences from the facts, and to
    appraise conflicting and circumstantial
    evidence. The credibility of witnesses and the
    probative value of particular testimony are for
    the ALJ to determine, and the ALJ may
    accept or reject in whole or part the testimony
    of any witness.

    [I]n reviewing a superior court order examining an agency
    decision, an appellate court must determine whether the
    agency decision (1) violated constitutional provisions; (2)
    was in excess of the statutory authority or jurisdiction of
    the agency; (3) was made upon unlawful procedure; (4) was
    affected by other error of law; (5) was unsupported by
    substantial admissible evidence in view of the entire
    record; or (6) was arbitrary, capricious, or an abuse of
    discretion.    N.C. Gen. Stat. § 150B–51 (2001). In
    performing this task, the appellate court need only
    consider those grounds for reversal or modification raised
    by the petitioner before the superior court and properly
    assigned as error and argued on appeal to this Court.

    Opinion of the Court
    North Carolina General Statute § 143-214.1 directs the North Carolina
    Environmental Management Commission to classify all bodies of water6 in the state
    and to adopt standards for each classification. See 
    N.C. Gen. Stat. § 143-214.1
     (2013),
    see also 
    N.C. Gen. Stat. § 143-212
     (2013). One body of water may include areas with
    different primary classifications and supplemental classifications, depending upon
    “the existing or contemplated best usage of the various streams and segments of
    streams in the basin, as determined through studies and evaluations and the holding
    of public hearings for consideration of the classifications proposed.” 15A N.C.A.C.
    2B.0301 (2013). The water quality standards applicable to a body of water are
    determined by the classification. See generally 15A N.C.A.C. 2B.0301 (2013). The
    primary classification of the portion of Blounts Creek at issue is Class C along with
    supplemental classifications of Sw (“swamp waters”) and NSW (“nutrient sensitive
    waters”). See generally 15A N.C.A.C. 2B.0101, .0301 (2013).
    Class C classification is appropriate for “freshwaters protected for secondary
    recreation, fishing, aquatic life including propagation and survival, and wildlife. All
    freshwaters shall be classified to protect these uses at a minimum.” 15A N.C.A.C.
    2B.0101 (2013). Sw classification applies to “waters which have low velocities and
    6 “(6) ‘Waters’ means any stream, river, brook, swamp, lake, sound, tidal estuary, bay, creek, reservoir,
    waterway, or other body or accumulation of water, whether surface or underground, public or private,
    or natural or artificial, that is contained in, flows through, or borders upon any portion of this State,
    including any portion of the Atlantic Ocean over which the State has jurisdiction.”

    other natural characteristics which are different from adjacent streams.” 
    Id.
     NSW
    classification applies to “waters subject to growths of microscopic or macroscopic
    vegetation required limitations on nutrient inputs.” 
    Id.
     More specifically, as to
    supplemental classifications, Sw is defined to “mean those waters which are classified
    by the Environmental Management Commission and which are topographically
    located so as to generally have very low velocities and other characteristics which are
    different from adjacent streams draining steeper topography.”           15A N.C.A.C.
    2B.0202. Nsw is defined to “mean those waters which are so designated in the
    classification schedule in order to limit the discharge of nutrients (usually nitrogen
    and phosphorus).” 
    Id.
    As for the broader classification of Class C, those water quality standards are
    provided in 15A N.C.A.C. 2B.0211, entitled “FRESH SURFACE WATER QUALITY
    STANDARDS FOR CLASS C WATERS[.]” See 15A N.C.A.C. 2B.0211. For Class C
    waters, pH “shall be normal for the waters in the area, which range between 6.0 and
    9.0 except that swamp waters may have a pH as low as 4.3 if it is the result of natural
    conditions[.]” 
    Id.
     The “Best Usage” of Class C waters is “aquatic life propagation and
    maintenance of biological integrity (including fishing and fish), wildlife, secondary
    recreation, agriculture, and any other usage except for primary recreation or as a
    source of water supply for drinking, culinary, or food processing purposes[.]”

    C.    Biological Integrity
    The trial court reversed the portion of the ALJ’s final decision regarding DEQ’s
    compliance with the biological integrity standards. Martin Marietta contends the
    superior court “Failed To Defer to DWR, Misinterpreted the Biological Integrity
    Standard, and Improperly Found Facts[.]” In other words, respondents argue the
    trial court made an error of law by misinterpreting the requirements of the applicable
    regulations as to “biological integrity;” misunderstood the science behind the
    applicable regulations; and failed to use the proper standard of review in addressing
    the issues before it. Martin Marietta specifically contends,
    The Superior Court failed to defer to DWR as it is
    required to do, misunderstood the permitting rules and
    what DWR did, and reversed the ALJ’s holding on
    biological integrity under the following erroneous analysis:
    (1) “DWR must protect the indigenous community”; (2) the
    “plain language” of the standard establishes “base line
    metrics” that must be “determined” or “measured” to apply
    the standard properly; and (3) without “determining the
    base line metrics,” DWR “could not ensure reasonable
    compliance” [sic] with the standard.
    (Ellipses omitted.)
    - 31 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Petitioners argue the superior court correctly interpreted the biological
    integrity standard:
    The issue before the Court is one of law: does the
    biological integrity standard require DWR to measure the
    terms in the rule and to protect the indigenous community
    of fish, insects, and other animals that live in Blounts
    Creek? The Superior Court recognized that under the
    lawful interpretation of the rule, DWR must measure the
    terms in the standard and establish specific reference
    conditions before issuing a permit.
    As the interpretation of the biological integrity standard applied by the superior court
    is an issue of law, we review this determination de novo. N. Carolina Dep’t of Pub.
    Safety, 
    247 N.C. App. at 286
    , 
    786 S.E.2d at 63
    .
    This issue requires consideration of how DEQ measures and evaluates
    “biological integrity” as part of its general duties in protecting water quality and in
    the context of issuance of a Permit. The ALJ made extensive findings of fact and
    conclusions of law on this issue,7 many of which Petitioners challenge:
    44.    Petitioners claim that, in issuing the NPDES
    Permit, DWR failed to reasonably ensure compliance with
    the biological integrity standard.
    7 In Petitioners’ brief to the superior court Petitioners challenge the findings of fact and conclusions of
    law in such a manner that it is difficult to keep track of what actually is at issue before the court. For
    instance, in paragraph 81 of Petitioners’ brief they challenge findings of fact “19, 23-25,” and then in
    paragraph 82 they challenge findings of fact “17-20, 22-25[,]” the latter which obviously encompasses
    the former and broadens it; this is but one of many such examples. Petitioners have divided their
    challenges based upon the topic they deem to be at issue, but for this Court’s purposes we simply note
    that Petitioners challenged many of the ALJ’s substantive findings of fact and conclusions of law as to
    biological integrity, but the challenges were so extensive we have not listed all of them, although we
    have considered all.
    - 32 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    45.    Under applicable North Carolina rules, one of the
    existing uses of all classified surface waters is
    “maintenance of biological integrity.” See 15A NCAC 02B
    .0211(1) (2013) (freshwater), and 02B .0220(1) (2013)
    (saltwater).
    46.   The term “biological integrity” is defined in 15A
    NCAC 02B .0202(11) as follows: “the ability of an aquatic
    ecosystem to support and maintain a balanced and
    indigenous community of organisms having species
    composition, diversity, population densities and functional
    organization similar to that of reference conditions.”
    47.   The biological integrity standards applicable to
    upper and lower Blounts Creek state:
    the waters shall be suitable for aquatic life
    propagation and maintenance of biological
    integrity . . . . Sources of water pollution
    which preclude any of these uses on either a
    short-term or long-term basis shall be
    considered to be violating a water quality
    standard . . . .
    15A NCAC 02B .0211(2) (2013) (freshwater standard). See
    also 15A NCAC 02B .0220(2) (2013) (same standard for
    saltwater).
    48.    DWR interprets the applicable rules and definitions
    to mean that an NPDES permit complies with the
    biological integrity standard if the permit’s terms and
    conditions reasonably ensure that the permitted discharge
    will not preclude maintenance of the ability of an aquatic
    ecosystem to support and maintain a balanced and
    indigenous community of organisms having species
    composition, diversity, population densities and functional
    organization similar to that of reference conditions.
    49.   The biological integrity standard is administered by
    DWR and relates to a highly technical and scientific subject
    area within DWR’s expertise.
    - 33 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    50.   As required by North Carolina case law and the
    APA, the undersigned accords deference and gives due
    regard to DWR’s interpretation of its own rules.
    51.    Even if the undersigned were not required to defer
    to DWR’s interpretation of the biological integrity standard
    rules, the undersigned finds that DWR’s interpretation is
    longstanding, is reasonable, and is consistent with and
    supported by the plain language of the rules, and therefore
    the undersigned will decide Petitioners’ biological integrity
    claim based on DWR’s interpretation of the rules.
    52.    The preponderance of the evidence shows that, in
    evaluating and determining whether the NPDES Permit
    reasonably ensures compliance with the biological
    integrity standard, DWR (through its staff) applied its
    knowledge and expertise, and:
    a.     identified the Blounts Creek system, meaning
    Blounts Creek and its tributaries, as the appropriate
    “aquatic ecosystem”;
    b.     determined that the appropriate “reference
    conditions” were the existing conditions of the
    Blounts Creek system before the proposed
    discharge;
    c.     studied and assessed the existing, pre-
    discharge ecological resources of the Blounts Creek
    system;
    d.     determined the degree and geographic scope
    of potential physical and chemical impacts of the
    proposed discharge;
    e.     determined the predicted changes to the
    ecosystem and ecological resources from the
    proposed discharge to be limited; and
    f.     concluded that the effects predicted to occur
    as a result of the permitted discharge would not
    violate the standard, and, in fact, a violation would
    not occur unless the impacts to the Blounts Creek
    aquatic ecosystem were much greater in degree and
    geographic scope than those predicted to occur.
    - 34 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    53.   Petitioners’ arguments that DWR misinterpreted
    and misapplied key aspects of the biological integrity
    standard and understated the effects of the permitted
    discharge present questions of law and fact, and mixed
    questions of law and fact. Petitioners’ arguments have
    been thoroughly considered and rejected by the
    undersigned as unpersuasive and unsupported by the
    preponderance of evidence.
    “Aquatic Ecosystem”
    54.   Petitioners have asserted that the relevant “aquatic
    ecosystem” should be defined more narrowly and that DWR
    must use a single stream segment as the ecosystem unit for
    assessing compliance. See Petition at 3.
    55.   The term “aquatic ecosystem” is not defined by
    North Carolina statute or rule.
    56.    The determination and application of “aquatic
    ecosystem” in a specific context is complex and requires
    significant scientific expertise and judgment, and should be
    accorded deference. See County of Durham v. N.C. Dept.
    of Environment and Natural Resources, 131 N.C. App. at
    396-97, 507 S.E.2d at 311 (1998), disc. rev. denied, 
    350 N.C. 92
    , 
    528 S.E.2d 361
     (1999).
    57.   DWR’s interpretation and application of this term
    are reasonable, rational, and in accordance with the
    language and purpose of the biological integrity standard.
    58.    To the extent DWR’s selection of an appropriate
    aquatic ecosystem is considered a factual determination, it
    is one which falls directly within the agency’s expertise and
    is therefore entitled to “due regard” pursuant to the APA.
    “Reference Conditions”
    59.   Petitioners have asserted that DWR failed to
    conduct a biological integrity analysis by inadequately
    - 35 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    sampling for “species composition, diversity, population
    densities and functional organization” throughout the
    Blounts Creek aquatic ecosystem.
    60.    The determination and application of “reference
    conditions” in a specific context is complex and requires
    significant scientific expertise and judgment, and should be
    accorded deference.
    61.   DWR’s interpretation and application of this term
    are reasonable, rational, and in accordance with the
    language and purpose of the biological integrity standard.
    62.    To the extent DWR’s selection of appropriate
    “reference   conditions”    is    considered     a    factual
    determination, it is one which falls directly within the
    agency’s expertise and is therefore entitled to “due regard”
    pursuant to the APA.
    63.    The preponderance of the evidence shows that
    Blounts Creek aquatic ecosystem’s existing conditions
    (“reference conditions”) are dynamic, vary over time and
    geographic location, and can be affected by many
    environmental factors.
    64.   The preponderance of the evidence shows that DWR
    had sufficient information such that the biological
    sampling efforts Petitioners sought were unnecessary.
    65.    Before issuing the Permit, DWR determined that:
    (a) the proposed discharge likely would not cause
    significant erosion or sedimentation; (b) pH likely would
    not exceed 6.9 in the upper Blounts Creek and was unlikely
    to change significantly in lower Blounts Creek; (c) relative
    salinity impacts would likely be on the order of 1 ppt and
    salinities would remain within the variability of the
    system; (d) shifts in macrobenthic invertebrates would
    likely be toward an increase in diversity and would be
    geographically limited to the upper reaches of Blounts
    Creek; and (e) the proposed discharge is not likely to
    - 36 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    adversely impact fish communities of the Blounts Creek
    aquatic ecosystem. These determinations by DWR are
    reasonable and supported by the preponderance of the
    evidence.
    66.   DWR determined that the likely effects of the
    permitted discharge are limited in degree, limited in
    geographic scope, and not deleterious.
    67.   The preponderance of the evidence supports DWR’s
    conclusion and shows that the permitted discharge will not
    have any significant detrimental effect on the Blounts
    Creek aquatic ecosystem, including the many miles of C
    and Sw stream segments of other tributaries of Blounts
    Creek.
    Impacts of the Proposed Discharge
    68.    Petitioners argued that DWR underestimated or
    understated the effects the proposed discharge will likely
    have on the Blounts Creek aquatic ecosystem, including
    effects on flow, pH, salinity, benthos, fish, and the existing
    biological community of Blounts Creek.
    69.    DWR’s findings and inferences regarding the
    predicted effects of the proposed discharge fall within
    “specialized knowledge of the agency.” As such, the
    undersigned is required to give such facts and inferences
    “due regard” pursuant to the APA. N.C. Gen. Stat. § 150B-
    34(a).
    70.    The preponderance of the evidence demonstrates
    that DWR applied its knowledge and expertise in its
    collection and review of the data and reports obtained
    during the permitting process, and drew reasonable
    inferences and conclusions based on those data and
    reports.
    71.   The preponderance of the evidence demonstrates
    that DWR reasonably evaluated and adopted the findings
    - 37 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    of the Kimley Horn reports (Exs. R13, R15) and the CZR
    report (Ex. R16) after satisfying itself of the reliability of
    these studies.
    72.    The preponderance of the evidence demonstrates
    that: (a) DWR applied its discretion and expertise in its
    review of the comments it received from the public
    (including Petitioners[]), EPA, and other state agencies
    during the permitting process; and (b) the substantive
    comments were considered and accounted for by DWR
    based on DWR’s expertise, judgment, and rational
    evaluation of the comments and other evidence.
    73.     To the extent Petitioners contend that DWR acted
    arbitrarily and capriciously in its evaluation of the
    evidence, its gathering and evaluation of relevant data and
    information, its interpretation and application of the
    biological integrity standard, and its conclusion that the
    NPDES Permit reasonably ensures compliance with the
    biological integrity standard, Petitioners failed to present
    any evidence that DWR acted “whimsically” or in “bad
    faith.”
    74.   The undersigned finds that DWR’s evaluation of the
    NPDES permit application, reports and data submitted
    during the permit process, the data independently collected
    by DWR, and the comments received from the public, state
    agencies and EPA was reasonable, rational, thorough,
    supported by a preponderance of the evidence in the record,
    and undertaken in good faith.
    75.   The undersigned finds the evidence and expert
    opinion testimony as well as the lay opinion testimony,
    even if admitted, presented by Petitioners, does not
    overcome DWR’s determinations, with respect to the likely
    impacts and effects of the permitted discharge, which were
    thoroughly evaluated based on DWR’s knowledge,
    expertise, and judgment, and well-supported by a
    preponderance of the evidence.
    - 38 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    76.   The undersigned has considered all of the evidence
    of potential impacts presented by Petitioners and their
    experts, and finds, based on a preponderance of the
    evidence, that Petitioners’ evidence either does not
    contradict DWR’s determinations or is not persuasive and
    not sufficient to overcome the data, studies, and other
    information reasonably considered and relied on by DWR
    in evaluating compliance with the biological integrity
    standard.
    77.   Petitioners failed to present evidence sufficient to
    overcome the presumption that DWR acted appropriately
    in determining the NPDES Permit reasonably ensures
    compliance with the biological integrity standard.
    78.   The preponderance of the evidence demonstrates
    that DWR:
    a.     reasonably     interpreted    the   biological
    integrity standard;
    b.     reasonably and rationally applied the
    biological integrity standard to the relevant
    information and facts regarding the proposed
    discharge;
    c.     reasonably determined that, although certain
    changes are predicted to occur as a result of the
    proposed discharge, the predicted effects would not
    preclude the ability of the relevant aquatic
    ecosystem to support and maintain a balanced and
    indigenous community of organisms having species
    composition, diversity, population densities and
    functional organization similar to that of reference
    conditions; and
    d.     reasonably and rationally determined that
    the NPDES Permit reasonably ensures compliance
    with the biological integrity standard.
    79.   Petitioners failed to meet their burden of proving by
    a preponderance of the evidence that DWR exceeded its
    authority or jurisdiction, acted erroneously, failed to use
    proper procedure, acted arbitrarily or capriciously, or failed
    - 39 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    to act as required by law or rule in determining the NPDES
    Permit reasonably ensures compliance with the biological
    integrity water quality standard. See 15A NCAC 02B.
    0202(11), 15A NCAC 02B .0211(2) (2013), and 15A NCAC
    02B .0220(2) (2013).
    80.   DWR’s decision that the NPDES Permit reasonably
    ensures compliance with the biological integrity water
    quality standard is affirmed.
    The superior court did not determine that any of the findings of fact made by
    the ALJ were unsupported by the record, but instead determined on de novo review
    that DWR’s interpretation of the “biological integrity standard rules and related
    definitions” was not reasonable and was “contrary to the language of the standard
    and definitions.” The superior court rejected both DEQ’s and the ALJ’s interpretation
    of the biological integrity standard, and Martin Marietta and DEQ challenge this
    conclusion on appeal as reflected in their arguments that the superior court “Failed
    To Defer to DWR, Misinterpreted the Biological Integrity Standard, and Improperly
    Found Facts[:]8”
    Class C waters must be “suitable for aquatic life
    propagation and maintenance of biological integrity”
    among other uses. 15A NCAC 02B.0211(2) The term
    “Biological Integrity” is defined by 15A NCAC 02B.202(11)
    as “the ability of an aquatic ecosystem to support and
    maintain a balanced and indigenous community of
    organisms having species composition, diversity,
    population densities and functional organization similar to
    that of reference conditions”.

    composition”, “diversity”, “population densities” or
    “functional organization”. Dr. Overton was offered and
    accepted by the AU as an expert in the field of fisheries
    ecology, larval fish ecology, fisheries management, and fish
    sampling methods and analysis. He testified that species
    composition counts the number of species in a system.
    Species diversity counts the number species present and
    the relative abundance of each species. Population density
    describes how many individuals are in a defined area and
    functional organization describes the organization of
    biological community.
    Tom Reeder with DWR testified that he did not
    know if there was such a thing as a biological integrity
    analysis; that he had never really heard of such a thing.
    He further testified that no statutes or rules set forth
    numeric standards or explicit methods or metrics by which
    DWR must make a determination that a NPDES permit
    reasonably ensures compliance with the biological
    integrity standard. Rather, the standard requires DWR to
    exercise its discretion, expertise and professional judgment
    to determine whether the anticipated impacts of a proposed
    discharge are such that the discharge will preclude the
    ability of an “aquatic ecosystem” to support and maintain
    a balanced and indigenous community of organisms having
    species composition, diversity, population densities, and
    functional organization “similar” to that of “reference
    conditions”. DWR staff conceded that the agency did not
    evaluate species composition, diversity, population
    density, or functional organization in Blounts Creek. Mr.
    Reeder justified the failure to evaluate these metrics by
    saying that he considered the impact of the permitted
    discharge to be de minimus. In essence the agency reached
    the ultimate conclusion that the impact of the permitted
    discharge was de minimus first, without evaluating species
    composition, diversity, population density, and functional
    organization, and then used the ultimate conclusion to
    conclude that evaluation of the metrics was unnecessary.
    With respect to questions of law, the reviewing court
    employs a de novo review. When applying de novo review,
    the Court may freely substitute its judgment for that of the

    agency. In re Appeal of N. C. Sav. & Loan League, 
    302 N. C. 458
     (1981) Incorrect statutory interpretation is an error
    of law which allows the court to apply a de novo review.
    Brooks v. Rebarco, 
    91 N.C. App. 459
     (1988) However even
    when reviewing a case de novo courts recognize the
    longstanding tradition of according deference to an
    agency’s interpretation of its rules. A reviewing Court
    should defer to agency’s interpretation of a statutes or
    rules it administers so long as the agency interpretation is
    reasonable and based upon a permissible construction of
    the statute or rule. County of Durham v. N.C. Dep’t of Env’t

    agency’s interpretation of its own regulations will be in
    enforced unless clearly erroneous or inconsistent with the

    The terms “species composition, diversity,
    populations densities, and functional organization” used in
    the biological integrity standard must be given meaning.
    Kyle v. Holston Group, 
    188 N.C. App. 686
     (2008) The
    standard requires DWR to maintain the indigenous
    biological community by insuring that the post discharge
    “species composition, diversity, population densities, and
    functional organization are similar to that of reference
    conditions” determined before the discharge is permitted.
    The rule is clear that referenced conditions must be
    evaluated on the basis of and as defined in those terms. Yet
    the DWR staff conceded that they did not measure any of
    the biological integrity metrics in Blounts Creek when
    evaluating the permit’s compliance with the standard.
    Thus, DWR failed to determine the base line metrics
    required by 15A NCAC 02B.0202(11) and could not,
    therefore, ensure reasonable compliance with the biological
    integrity standard.
    The Biological integrity standard is clear; DWR
    must protect the indigenous community by determining
    reference conditions in terms of an evaluated impacts on
    - 42 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    the community’s species composition, diversity, population
    density and functional organization. Reference conditions
    must be specific enough to allow the agency to apply the
    biological integrity standard properly. DWR failed to apply
    the plain language of the biological integrity standard.
    Therefore DWR did not “reasonably ensure compliance
    with” the biological integrity standard. Consequently the
    agency exceeded its authority and erred as a matter of law
    when issuing the permit. Based upon a de novo review of
    the biological integrity standard rules and related
    definitions the Court concludes that DWR’s interpretation
    of the rule is not reasonable and is contrary to the language
    of the standard and definitions.
    Conclusions of law 51 through 53, 61, 62, 64 through
    67,70, 75, 77 through 80, 110 through 112 are reversed. 9
    Ultimately, the superior court determined, contrary to the ALJ’s conclusion,
    that DEQ’s interpretation of the biological integrity standard was not reasonable and
    was contrary to the language of the standard and definitions. The superior court did
    not determine that the ALJ’s findings of fact were unsupported by substantial
    evidence but instead found legal error as to the meaning and application of the
    biological integrity standard. The primary difference between the ALJ’s order and
    the superior court’s order is its determination of the “clear” meaning of the biological
    integrity standard and its resulting determination not to defer to agency expertise.
    Again, the superior court concluded that
    [t]he Biological integrity standard is clear; DWR
    must protect the indigenous community by determining
    reference conditions in terms of an evaluated impacts on
    the community’s species composition, diversity, population

    Opinion of the Court
    density and functional organization. Reference conditions
    must be specific enough to allow the agency to apply the
    biological integrity standard properly. DWR failed to apply
    the plain language of the biological integrity standard.
    But as the superior court notes, many of the operative words in the applicable
    regulations are not defined.     Despite the superior court’s conclusion that “the
    Biological integrity standard is clear[,]” it could be clear only to the extent the
    operative terms in the standard are defined. However, the superior court applied
    “clear” definitions where the regulations simply do not provide definitions. The
    superior court defined the biological integrity standard to mean that “DWR must
    protect the indigenous community by determining reference conditions in terms of an
    evaluated impacts on the community’s species composition, diversity, population
    density and functional organization.” But this is not the standard as defined by the
    applicable regulations.    Again, classification is determined by “the existing or
    contemplated best usage of the various streams and segments of streams in the basin,
    as determined through studies and evaluations and the holding of public hearings for
    consideration of the classifications proposed.” 15A N.C.A.C. 2B.0301 (2013)
    (emphasis added). The North Carolina Administrative Code (“Code”) contemplates
    the existing state of the water or its possible best usage. See 
    id.
     The “Best Usage” of
    Class C waters is “aquatic life propagation and maintenance of biological integrity
    (including fishing and fish), wildlife, secondary recreation, agriculture, and any other
    usage except for primary recreation or as a source of water supply for drinking,
    - 44 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    culinary, or food processing purposes[.]” 15A N.C.A.C. 2B.0211. “Conditions Related
    to Best Usage” note “the waters shall be suitable for aquatic life propagation and
    maintenance of biological integrity, wildlife, secondary recreation, and agriculture.
    Sources of water pollution which preclude any of these uses on either a short-term or
    long-term basis shall be considered to be violating a water quality standard.” 
    Id.
    (emphasis added).
    The Code does not require the biological integrity of an aquatic ecosystem to
    remain exactly or even substantially the same as it had once been, for example, prior
    to discharge. See generally 15A N.C.A.C. 2B.0301.        To violate a water quality
    standard, the discharge of water must “preclude any of these uses on either a short-
    term or long-term basis[.]” 15A N.C.A.C. 2B.0211. “Preclude” is not defined in the
    statute, but its ordinary meaning is to “close” and “to make impossible by necessary
    consequence: rule out in advance[.]” Merriam-Webster’s Collegiate Dictionary 977
    (11th ed. 2003). In other words, to violate a water quality standard the discharge of
    water must make “aquatic life propagation and maintenance of biological integrity,
    wildlife, secondary recreation, and agriculture” nearly impossible. 15A N.C.A.C.
    2B.0211; see generally Merriam-Webster’s Collegiate Dictionary 977.
    Further, the superior court did not reverse the ALJ’s findings of fact as to
    DEQ’s expertise applying the regulations which ultimately led to the contested
    conclusion by the ALJ that DEQ had complied with the biological integrity standard:
    - 45 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    131. Mr. Reeder testified that with the assistance of DWR
    staff, he used his best professional judgment, experience
    and expertise to determine that the appropriate “aquatic
    ecosystem” was the watershed system of Blounts Creek
    and its tributaries. (Reeder, Tr. Vol. 7 pp. 1149-1150)
    132. Mr. Reeder considered “reference conditions” to be
    the existing conditions in the Blounts Creek aquatic
    ecosystem without the proposed discharge. (Reeder, Tr.
    Vol. 7 pp. 1142-1144, 1149-1150; Reeder, Tr. Vol. 4 pp. 662-
    663; Fleek, Tr. Vol. 6 pp. 992-993)
    ....
    136. Mr. Reeder took into consideration and weighed Mr.
    Fleek’s opinions regarding the effects of the proposed
    discharge on benthos in the upper reaches immediately
    downstream of the proposed discharge outfalls. (Reeder,
    Tr. Vol. 4 pp. 660-661)
    137. Mr. Reeder understood Mr. Fleek’s professional
    opinion to be that benthic macroinvertebrates would likely
    become more diverse near the discharge outfalls and that
    farther downstream any such impacts would lessen or
    dissipate. (Reeder, Tr. Vol. 4 pp. 660-661)
    138. Mr. Reeder also understood that the many other
    tributaries of the Blounts Creek aquatic ecosystem, and the
    biota inhabiting those areas, would be unaffected by the
    permitted discharge. (Reeder, Tr. Vol. 7 pp. 1142-1151,
    1162-1165, 1172; Reeder, Tr. Vol. 4 pp. 658-671; Ex. R23;
    Ex. R1; Ex. R16)
    Despite these findings of fact, Petitioners argued, and the Superior Court found, that
    DEQ’s interpretation of the regulations and process for evaluation of the impact of
    the proposed discharge were not “reasonable” and thus not subject to deference.
    One of respondents’ main contentions before this Court is that the superior
    - 46 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    court failed to apply the correct legal standard in deferring to DEQ as to the
    interpretation and application of the biological integrity standards. The superior
    court determined “DWR failed to determine the base line metrics required by 15A
    NCAC 02B.0202(11) and could not, therefore, ensure reasonable compliance with the
    biological integrity standard,” but, according to Mr. Reeder, “no statutes or rules set
    forth numeric standards or explicit methods or metrics by which DWR must make a
    determination that a NPDES permit reasonably ensures compliance with the
    biological integrity standard.” As DEQ explains,
    the Superior Court’s “plain language” interpretation is not
    based on the plain language of applicable regulations at all.
    By stepping outside the plain language of the regulations
    and dictating what information the agency’s biologists and
    engineers must consider when evaluating compliance with
    a technical environmental standard, the Superior Court
    improperly substituted its judgment for that of the agency
    . . . [, and]
    ....
    As a pure question of regulatory interpretation, the
    Superior Court’s “plain language” reading is flatly
    incorrect. The “plain language” of the standard says
    nothing about what process the agency must go through or
    what information the agency must collect to reasonably
    ensure compliance with the standard.             Rather, the
    regulations leave this determination to the “reasonabl[e]”
    discretion of DWR’s environmental scientists to be
    evaluated on a case-by-case basis. 15A NCAC 2H.0112(c).
    The superior court considered a few lines of testimony of Mr. Reeder, “Tom
    Reeder with DWR testified that he did not know if there was such a thing as a
    biological integrity analysis; that he had never really heard of such a thing.” But this
    - 47 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    interpretation takes the testimony out of context and is not supported by the whole
    record as noted by the next sentence in the order noting he further testified accurately
    “that no statutes or rules set forth numeric standards or explicit methods or metrics
    by which DWR must make a determination that a NPDES permit reasonably ensures
    compliance with the biological integrity standard.” In fact, the superior court did not
    determine that the ALJ’s findings regarding DEQ’s investigation of the expected
    effects of the water discharge on biological integrity were not supported by the whole
    record, but relied upon this statement by Mr. Reeder along with an erroneous
    definition of “biological integrity” to conclude that
    DWR staff conceded that the agency did not evaluate
    species composition, diversity, population density, or
    functional organization in Blounts Creek. Mr. Reeder
    justified the failure to evaluate these metrics by saying
    that he considered the impact of the permitted discharge to
    be de minimus. In essence the agency reached the ultimate
    conclusion that the impact of the permitted discharge was
    de minimus first, without evaluating species composition,
    diversity, population density, and functional organization,
    and then used the ultimate conclusion to conclude that
    evaluation of the metrics was unnecessary.
    But DEQ certainly did not “concede[]” that it “did not evaluate specifies
    composition, diversity, population density, or functional organization[]” despite the
    portions of Mr. Reeder’s testimony the superior court and Petitioners take out of
    context.    DEQ simply did not perform evaluations to Petitioners’ desired
    specifications, but this is vastly different from failing to evaluate at all. The question
    - 48 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    for the superior court, and for this Court, is not whether DEQ could have done more
    or different testing or analysis or whether the ALJ could have found different facts.
    The questions before us are whether the ALJ’s findings of fact are supported by the
    whole record; N. Carolina Dep’t of Pub. Safety, 
    247 N.C. App. at 286
    , 
    786 S.E.2d at 64

    regulations; and whether DEQ’s interpretation of those regulations was reasonable.

    even though it could reasonably have reached a different result had it reviewed the
    matter de novo. Instead, we must examine all the record evidence—that which
    detracts from the ALJ’s findings and conclusions as well as that which tends to
    support them—to determine whether there is substantial evidence to justify the
    ALJ’s decision. Substantial evidence is relevant evidence a reasonable mind might
    accept as adequate to support a conclusion. We undertake this review with a high

    degree of deference because it is well established that in an administrative proceeding,
    it is the prerogative and duty of the ALJ, once all the evidence has been presented
    and considered, to determine the weight and sufficiency of the evidence and the
    credibility of the witnesses, to draw inferences from the facts, and to appraise
    conflicting and circumstantial evidence. The credibility of witnesses and the probative
    value of particular testimony are for the ALJ to determine, and the ALJ may accept or
    reject in whole or part the testimony of any witness.” (emphasis added)).
    The whole record supports the ALJ’s findings that DEQ evaluated species
    composition, diversity, population density, and functional organization in accord with
    its established procedures and expertise. Mr. Reeder was “the acting director of the
    Division of Water Quality and the director of the Division of Water Resources” when
    the Permit was approved; eventually the two divisions were merged. Mr. Reeder
    approved the Permit, but he was by no means the only employee of DEQ involved in
    the consideration of the Permit. Many employees of DEQ, as well as consultants
    including CZR Incorporated (“CZR”) and Kimley-Horn and Associates (“Kimley
    Horn”), performed the actual sampling and analysis of water quality, fish, and
    benthos in Blounts Creek.        Mr. Reeder testified at length regarding DEQ’s
    investigation and analysis of “biological integrity” in Blount’s Creek. As a whole, in
    context, Mr. Reeder testified “biological integrity” is a narrative standard, not a
    numeric standard:
    - 50 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Well, I mean you can’t go to an [Standard Operating
    Procedure]—there’s no [Standard Operating Procedure]
    that says biological integrity analysis. Like I couldn’t call
    Eric Fleek on the phone and say, “Hey, Eric, go out and do
    a biological integrity analysis.”
    What you do is you go out and do exactly what Eric
    did, is you do a biological assessment and you look at the
    technical memorandum, and according to that you make a
    decision based upon your best professional judgment and
    all the data as to whether you think this narrative
    standard for biological integrity will be violated or not.
    Mr. Eric Fleek was an environmental supervisor at DEQ. Mr. Fleek testified his
    branch, the Biological Assessment Branch, evaluated water quality by “sampling for
    fish. We also do sampling for benthic macroinvertebrates. And by assessing a water
    body and the biology that lives there, you can use them as proxies to determine what
    the water quality is like there.” Mr. Fleek also testified that there were “protocols for
    doing that sampling” of Blounts Creek in reference to the Standard Operating
    Procedure.
    Our record contains one of Petitioners’ exhibits in arguing DEQ failed to
    comply with its own standards, DEQ’s “STANDARD OPERATING PROCEDURE
    BIOLOGICAL MONITORING[,] STREAM FISH COMMUNITY ASSESSMENT
    PROGRAM[,]” (“Standard Operating Procedures”) and
    the purpose of this manual [is] to provide details on
    standard operating procedures of the Biological
    Assessment Unit of the Division of Water Quality (DWQ or
    Division) for the collection and analysis of stream fish
    community assessment data.          Consistency in data
    collection and analysis is the cornerstone for evaluating
    - 51 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    biological integrity.   The procedures provided are a
    synthesis of widely used methods and methods developed
    from the experience of personnel within the Unit. These
    methods have been shown to provide repeatable and useful
    data for water quality evaluation.
    ....
    The Stream Fish Community Assessment Program
    was designed as an additional basinwide assessment tool
    and has been in existence since 1991. It’s core mission is
    to sample a set of fixed sites on lower Strahler order
    wadeable creeks, streams, and rivers on a five-year
    rotating basis to support the DWQ’s Basinwide
    Management Plan Program.
    While the Standard Operating Procedures address “biological integrity[,]” they
    do not require a particular type of analysis to be done for a Permit application;
    instead, the staff of DEQ uses its expertise to determine what types of testing or
    sampling need to be done for each application, depending upon its unique
    circumstances.
    The Standard Operating Procedures also describe the “NORTH CAROLINA
    INDEX OF BIOTIC INTEGRITY” which has been in use since the early 1990s:
    The Division has been monitoring the biological integrity
    of stream fish communities since the early 1990s. The
    biological monitoring tool that is used is referred to as the
    North Carolina Index of Biological Integrity (NCIBI). The
    NCIBI method was developed for assessing a stream’s
    biological integrity by examining the structure and health
    of its fish community. The North Carolina Administrative
    Code defines Biological Integrity as: “. . . the ability of an
    aquatic ecosystem to support and maintain a balanced and
    indigenous community of organisms having species
    composition, diversity, population densities, and functional
    organization similar to that of reference conditions” (15A
    - 52 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    NCAC 02B .0200; NCAC 2004).             The NCIBI is a
    modification of the Index of Biotic Integrity (IBI) initially
    proposed by Karr (1981) and Karr, et al. (1986).
    The NCIBI incorporates information about species
    richness and composition, trophic composition, fish
    abundance, and fish condition. The NCIBI summarizes the
    effects of all classes of factors influencing aquatic faunal
    communities such as water quality, energy source, habitat
    quality, flow regime, and biotic interactions. While any
    change in a fish community can be caused by many factors,
    certain aspects of the community are generally more
    responsive to specific influences. Species composition
    measurements reflect habitat quality effects. Information
    on trophic composition reflects the effect of biotic
    interactions and energy supply. Fish abundance and
    condition information indicates additional water quality
    effects. It should be noted, however, that these responses
    may overlap. For example, a change in fish abundance may
    be due to decreased energy supply or a decline in habitat
    quality, not necessarily a change in water quality.
    The scores derived from this index are a measure of the
    ecological health of the waterbody and may not directly
    correlate to water quality. For example, a stream with
    excellent water quality, but with poor or fair fish habitat,
    may not be rated excellent with this index. However, a
    stream which rated excellent on the NCIBI should be
    expected to have excellent water quality.
    Further, the NCIBI sets out specific metrics to assess biological integrity:
    The NCIBI incorporates information about species
    richness and composition, pollution indicator species,
    trophic composition, fish abundance, fish condition, and
    reproductive function by the cumulative assessment of 12
    parameters or metrics (Tables 1-3). Each metric is
    designed to contribute unique information to the overall
    assessment. The values provided by the metrics are
    converted into scores on a 1, 3, and 5 scale. A score of 5
    - 53 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    represents conditions commonly associated with
    undisturbed reference streams in the specific river basin or
    ecoregion. A score of 1, however, indicates that conditions
    deviate greatly from those typically observed in
    undisturbed streams of the region. All metrics for each of
    the three regions were calibrated using regional reference
    sites.
    The scores for all metrics are then summed to obtain the
    overall NCIBI score, an even number between 12 and 60.
    The score is then used to determine the biological integrity
    class of the stream (i.e., Poor, Fair, Good-Fair, Good, or
    Excellent) (Karr 1981 , Karr, et al. 1986). A fish community
    rated Excellent is comparable to the best situations with
    minimal human disturbance; all regionally expected
    species for the habitat and stream size, including the most
    intolerant forms, are present along with a full array of size
    classes and a balanced trophic structure. Conversely, a
    fish community rated Poor deviates greatly from the
    reference condition. The number of fish is fewer than
    expected, usually fewer than expected number of species,
    an absence of intolerant species, and an altered trophic
    structure. Communities rated Good, Good-Fair, or Fair fall
    within this disturbance gradient.
    Currently, if a fish community is rated Excellent, Good, or
    Good-Fair it is deemed to be Fully Supporting its Aquatic
    Life Use Support stream classification. If a fish community
    is rated Fair or Poor it is deemed to be Not Supporting its
    Life Use Support stream classification and the water
    quality standard is not being met. Waters that have an
    Excellent fish community rating are also eligible for
    reclassification to a[n] Outstanding Resource Waters or to
    a High Quality Waters supplemental classifications.
    The Standard Operating Procedures set forth twelve metrics, grouped into five
    categories:
    1.     Species richness and composition (Metric Nos. 1 and
    - 54 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    3-5)
    2.     Indicator species (Metric Nos. 6 and 7)
    3.     Trophic function (Metric Nos. 8-10)
    4.     Abundance and condition (Metric Nos. 2 and 11)
    5.     Reproductive function (Metric No. 12)
    The particular metrics used may vary depending upon the type of water and region
    of the state. For example, the species of fish measured metric number 4 are different
    in mountain streams than in and around coastal waters. The Standard Operating
    Procedures also set out sampling procedures and instructions for laboratory
    processing for samples. To assess the quality of a stream, information obtained from
    sampling is compared to reference conditions. “The scores for all 10 or 12 metrics are
    then summed to obtain the overall NCIBI score. Finally, the score (an even number
    between 12 and 60) is then used to determine the biological integrity class of the
    stream from which the sample was collected[.]”
    Regarding permits, the Standard Operating Procedures provide, “The location
    of permitted dischargers should be reviewed, using the database provided by the
    Division’s Basinwide Information Management System” and notes that “[w]atershed-
    specific special study sites that are designed to address a specific, short-term question
    (e.g.,   Use Attainability,    impacts from         a permitted discharger,   watershed
    modifications, etc.) are usually sampled only once and may be sampled anytime
    between March and December.” (Emphasis added.)
    - 55 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    As part of its analysis of the permit application, CZR did sampling and
    prepared a report addressing the metrics noted in the Standard Operating
    Procedures regarding fish and benthos. This report noted that fish surveying was
    done “in accordance with NCDWQ 2006 Standard Operating Procedure, Stream Fish
    Community Assessment Program (NCDENR 2006a).” “Benthic invertebrate
    sampling occurred on 11 April 2011 following the swamp stream method as described
    in NCDWQ 2006 Standard Operating Procedures for collection of benthic
    invertebrates in the Level IV Ecoregion Swamp Region B of the coastal plain of North
    Carolina NCDENR 2006b.”
    DEQ initially reviewed Martin Marietta’s application for the Permit, then
    requested additional information to address several questions:
    1.     Please define a zone of impact (ZOI) and show that
    it is not degraded, considering hydraulic, biota, & saline
    water impacts as discussed below.
    Hydraulic: The point downstream at which the
    proposed discharge can be considered insignificant.
    Consider the frequency of bank overflow and the
    effects of increased water levels, velocity changes,
    and erosion. Impacts should be based on a major
    rainfall event such as an 80th percentile (two in 10-
    year) storm, and a base flow.
    Biota: The point at which the proposed discharge is
    considered to be insignificant, relative to
    anadromous fish (e.g. finfish) changes in velocity,
    pH, temperature DO. Evaluate effects during
    documented spawning times (as per the NC Wildlife
    Resources Commission and the National Marine
    Fisheries Service) and during periods of lower
    stream flows.

    Saline Water:       The point at which the
    freshwater impact of the proposed discharge is
    considered insignificant. Using the ZOI identified
    for the hydraulic component, determine the distance
    to a downstream point of saline stability and
    evaluate impacts
    2.     Please provide a process flow diagram for the mine
    dewatering and stormwater discharge, including the flow
    around the proposed stockpile area.           What is the
    approximate size and capacity of the settling pond that will
    be located next to the mining pit?
    3.     What is the size and capacity of the closed loop
    settling system and the future overburden storage area?
    4.     Please    provide    an    expanded     Engineering
    Alternatives Analysis (EAA). This should include the
    alternatives of reinjection of pit drainage and the
    treatment and conveyance of this discharge for potable or
    other reusable purposes. The EAA must be performed
    according to the guidelines in the Division’s website. This
    includes a 20-year present worth analysis of all feasible
    options.
    In answer to these questions, Martin Marietta provided a Technical
    Memorandum prepared by Kimley Horn summarizing “the results of several analyses
    performed to address comments regarding stream stability, potential flooding, and
    water quality issues associated with the proposed discharge[,]” including “the
    predicted zones of potential impact[;]” a revised NPDES Water Flow Map showing
    “the process flow diagram for mine dewatering and stormwater discharge[;] and
    “expanded Engineering Alternatives Analysis (EAA) dated September 14, 2012,
    prepared by Groundwater Management Associates, Inc. . . . according to the
    guidelines in the DWQ website and includ[ing] a 20-year present worth analysis of
    - 57 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    all feasible options.” Further, in October of 2012, CZR also prepared a Technical
    Memorandum addressing “potential direct and indirect effects on identified fish
    populations from predicted changes in Blounts Creek water quality as identified by”
    Kimley Horn’s Technical Memorandum.
    In summary, hundreds of pages of the record on appeal and hundreds of pages
    of testimony address the analysis of “biological integrity,” as well as salinity, pH, and
    many other factors evaluated by DEQ to determine whether the Permit should be
    issued. To the extent that the superior court made a finding of fact in noting that
    Tom Reeder with DWR testified that he did not
    know if there was such a thing as a biological integrity
    analysis; that he had never really heard of such a thing.
    He further testified that no statutes or rules set forth
    numeric standards or explicit methods or metrics by which
    DWR must make a determination that a NPDES permit
    reasonably ensures compliance with the biological
    integrity standard[,]
    this finding is technically supported by the record because Mr. Reeder did so testify.
    But neither the superior court nor this Court may substitute its findings of fact for
    those of the ALJ; we review the ALJ’s findings of fact only to determine if they are
    supported by the whole record. See Ledford, 247 N.C. App. at 286–87, 786 S.E.2d at
    63–64. The ALJ’s findings are supported by the whole record, as discussed above.
    Contrary to the superior court’s conclusions, Mr. Reeder’s testimony indicated the
    thorough and extensive evaluation that DEQ undertook to ensure biological integrity,
    although this cannot be neatly summed up as one official analysis plainly laid out in
    - 58 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    a specific standard operating procedure. The ALJ’s findings as to the biological
    integrity analysis are supported by the whole record. The superior court therefore
    erred by essentially substituting its own findings of fact regarding Mr. Reeder’s
    testimony and by making legal conclusions as to biological integrity based upon a
    misinterpretation of the standard. Therefore, as to DEQ’s and Martin Marietta’s
    main contention on appeal we agree that the trial court erred in reversing the ALJ’s
    order as to the biological standard, and we now turn to address Petitioners’ issues on
    cross-appeal.
    D.    Swamp Waters Classification
    Petitioners cross-appealed from the superior court’s order based upon its
    determination that DEQ’s approval of the Permit violated the water quality
    standards set forth for swamp water classification. DEQ and Martin Marietta argue
    we should affirm the findings and conclusions of the ALJ and superior court regarding
    swamp waters.      As noted above, a body of water may have a supplemental
    classification in addition to its primary classification. See generally 15A N.C. Admin.
    Code 2B.0301.     The portions of Blounts Creek at issue have a supplemental
    classification of “swamp waters” which again is defined as “those waters which are
    classified by the Environmental Management Commission and which are
    topographically located so as to generally have very low velocities and other
    characteristics which are different from adjacent streams draining steeper
    - 59 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    topography.” 15A N.C.A.C. 2B.0202. Swamp water classification applies to “waters
    which have low velocities and other natural characteristics which are different from
    adjacent streams.” 15A N.C.A.C. 2B.0101.
    The ALJ identified the issue regarding swamp waters as follows:
    Issue 2: “Swamp Waters Claim”: Whether Petitioners
    have met their burden of proving that Respondent
    exceeded its authority or jurisdiction, acted erroneously,
    failed to use proper procedure, acted arbitrarily or
    capriciously, or failed to act as required by law or rule in
    determining the NPDES Permit reasonably ensures
    compliance with water quality standards and regulations
    related to      the “Swamp Waters” supplemental
    classification.
    The ALJ made the following findings regarding the swamp water
    classification:
    18.   Contrary to Petitioners’ assertions, the evidence
    demonstrates that the “swamp method” and the term
    “swamp stream” in the SOP are unrelated to the “swamp
    waters” supplemental classification. (Fleek, Tr. Vol. 7 pp.
    1103-1105; Ex. R34, p.6; Fleek, Tr. Vol. 6 pp. 980-981; Ex.
    P58; Ex. P59)
    19.    Mr. Fleek reviewed the CZR Habitat Assessment
    and provided input to Mr. Belnick. In Mr. Fleek’s
    evaluation, he concluded that there could be an increase in
    diversity and population of benthos near the proposed
    discharge outfalls because the discharge would lead to less
    stressful conditions. (Fleek, Tr. Vol. 7 pp. 1108-1111, 1114-
    1116; Ex.R4; Ex. 51)

    Petitioners’ Swamp Waters Claim
    - 60 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    81.   Petitioners claim that the NPDES Permit does not
    reasonably ensure compliance with what Petitioners
    characterize as a requirement to “protect” swamp waters
    “characteristics.” Petition 4-5.
    82.    “Swamp Waters” are defined as “waters which are
    classified by the Environmental Management Commission
    and which are topographically located so as to generally
    have very low velocities and other characteristics which are
    different from adjacent streams draining steeper
    topography.” 15A NCAC 02B.0202(62). See also 15A
    NCAC 02B.0101(e)(2) and 02B .0301(c).
    83.   Petitioners claim that DWR has a duty to preserve
    swamp waters in their existing condition, and they objected
    to the predicted changes in physical and chemical
    parameters in upper Blounts Creek, specifically dissolved
    oxygen, pH, flow velocity, and tannins. Petitioners have
    characterized the predicted changes to these parameters as
    unlawfully eliminating swamp waters characteristics and
    uses.
    84.    DWR disagrees with Petitioners in that DWR has a
    duty under the applicable rules and laws to preserve
    waters with the supplemental classification “swamp
    waters” in their existing condition.         DWR asserts,
    consistent with its longstanding interpretation and past
    practices, that the only effect of the Sw supplemental
    classification is to modify the water quality standards for
    dissolved oxygen and pH by lowering the minimum limits
    otherwise required for Class “C” waters. See 15A NCAC
    02B .0211(3)(b) and (3)(g) (2013).
    85.   Petitioners failed to identify any statute or rule that
    expressly protects “low tannins”, “low pH”, “low dissolved
    oxygen”, or “low velocity” attributes of swamp waters.
    86.    Petitioners have not cited a law or rule that requires
    additional protection or use for waters with the
    - 61 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    supplemental classification “swamp waters.”
    87.   The swamp waters supplemental classification and
    the water quality standards administered by DWR relate
    to a highly technical and scientific subject area within
    DWR’s expertise.
    88.    As the agency delegated the responsibility for
    NPDES permitting and enforcement of North Carolina’s
    water quality standards, DWR’s interpretation and
    application of the State’s water quality standards, and its
    surface     water    classifications   and   supplemental
    classifications are entitled to deference. Hilliard v. N.C.
    Dept. of Corrections, 
    173 N.C. App. 594
    , 598, 
    620 S.E.2d 14
    , 17-18 (2005).
    89.    DWR’s interpretation and application of the highly
    technical rules it administers, including the swamp waters
    and antidegradation rules, are reasonable, longstanding,
    in accord with past DWR practices, and consistent with and
    supported by the plain language of the relevant rules.
    90.    Petitioners have presented no evidence, authority,
    or argument that persuades the undersigned to overrule
    DWR’s rational interpretation and application of the
    State’s swamp waters and antidegradation laws and rules.
    91.    Some supplemental classifications may trigger
    protection or uses in addition to the protections or uses for
    Class C waters. For example, the “Outstanding Resource
    Waters” supplemental classification states that such
    waters “require special protection to maintain existing
    uses.” 15A NCAC 02B .0101(e)(4).
    92.    The specificity of additional protections and uses
    explicitly applicable by rule to some supplemental
    classifications is further evidence that, if the “swamp
    waters” supplemental classification was intended to
    provide additional protections, the rules would have
    specifically provided for such protections.      See, e.g.,
    - 62 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Mangum v. Raleigh Bd. Of Adjustment, 
    196 N.C. App. 249
    ,
    255, 
    674 S.E.2d 742
    , 747 (2009) (“One of the longstanding
    rules of interpretation and construction in this state is
    expressio unius est exclusio alterius, the expression of one
    thing is the exclusion of another.”) (citations omitted).
    93.    The term “swamp waters” is a regulatory term that
    guides the assignment of the Sw supplemental
    classification to particular stream segments; and once the
    assignment is made by rule, the only regulatory effect of
    the assignment of the swamp waters supplemental
    classification is to lower the acceptable minimum values
    for pH and dissolved oxygen. See 15A NCAC 02B
    .0211(3)(b) and (3)(g) (2013). Upper Blounts Creek, for
    example, has been assigned the “Sw” supplemental
    classification by formal rulemaking. 15A NCAC 02B
    .0316(a) (Index Number 29-9-1-(1)).
    94.    Petitioners’ arguments that DWR misinterpreted
    and misapplied the swamp waters supplemental
    classification present questions of law and fact, and mixed
    questions of law and fact. Petitioners’ arguments have
    been thoroughly considered and rejected by the
    undersigned as unpersuasive and unsupported by the
    preponderance of evidence.
    95.    Petitioners rely on a sentence from the State’s
    antidegradation policy: “Existing uses, as defined by Rule
    .0202 of this Section, and the water quality to protect such
    uses shall be protected by properly classifying surface
    waters and having standards sufficient to protect these
    uses.” 15A NCAC 02B .0201(b). See Petition at 4-5.
    96.    According to its plain language, this provision is
    implemented by formal rulemaking that establishes
    classifications, uses and water quality standards, and that
    assign classifications, uses and standards to individual
    surface water segments. See, e.g., 15A NCAC 02B .0211
    (2013) (uses and standards for Class C waters, including
    waters with the supplemental “Sw” classification), 15A
    - 63 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    NCAC 02B .0316(a) (Index Number 29-9-1-(1) (assignment
    of classifications to upper Blounts Creek).
    97.   There are antidegradation permitting procedures
    that did apply to DWR’s evaluation and issuance of the
    NPDES Permit, but Petitioners have not argued that these
    applicable procedures were not followed.
    98.    The preponderance of the evidence demonstrates
    that DWR reasonably interpreted the laws and rules
    governing swamp waters and the state’s antidegradation
    policy, and reasonably applied those laws and rules to the
    data, studies, and other information submitted or obtained
    during the course of DWR’s NPDES permitting review and
    decision.
    99.    Petitioners failed to present evidence sufficient to
    overcome the presumption that DWR acted appropriately
    in determining the NPDES Permit reasonably ensures
    compliance with water quality standards or regulations
    related to      the “Swamp Waters” supplemental
    classification.
    100. Petitioners failed to meet their burden of proving by
    a preponderance of the evidence that DWR exceeded its
    authority or jurisdiction, acted erroneously, failed to use
    proper procedure, acted arbitrarily or capriciously, or failed
    to act as required by law or rule in determining that the
    laws and rules do not require protection of the existing
    conditions or characteristics of surface waters with the
    supplemental classification “swamp waters” and that the
    NPDES Permit reasonably ensures compliance with water
    quality standards and rules related to the “Swamp Waters”
    supplemental classification.
    101. DWR’s decision that the NPDES Permit reasonably
    ensures compliance with all applicable water quality
    standards and rules, including those relating to the swamp
    waters supplemental classification, is affirmed.
    - 64 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    ....
    110. Petitioners failed to present evidence sufficient to
    overcome the presumption that DWR acted appropriately
    in issuing the Permit.
    111. Petitioners failed to meet their burden of proving
    Respondent DWR exceeded its authority or jurisdiction,
    acted erroneously, acted arbitrarily and capriciously, used
    improper procedure, or failed to act as required by law or
    rule in issuing the NPDES Permit.
    112.   DWR’s issuance of the NPDES Permit is affirmed in
    all respects.
    ....
    119. Petitioners contend that the NPDES Permit is
    unlawful because the Permit does not reasonably ensure
    compliance with what Petitioners characterize as a
    requirement to “protect” swamp waters “characteristics,”
    which they contend include “low velocity,” “low dissolved
    oxygen,” “low pH,” and “high tannins.” (Petition 4-5)
    120. “Swamp Waters” are defined as “waters which are
    classified by the Environmental Management Commission
    and which are topographically located so as to generally
    have very low velocities and other characteristics which are
    different from adjacent streams draining steeper
    topography.” 15A NCAC 2B.0202(62). See also 15A NCAC
    2B .0101(e)(2) and 2B .0301(c).
    121. The “swamp waters” supplemental classification
    modifies the water quality standards for dissolved oxygen
    and pH in the upper Blounts Creek segment by lowering
    the minimum pH and dissolved oxygen values otherwise
    required for Class “C” waters:
    (b) Dissolved oxygen: . . . for non-trout waters, not
    less than a daily average of 5.0 mg/1 with a
    - 65 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    minimum instantaneous value of not less than 4.0
    mg/1; swamp waters, lake coves or backwaters, and
    lake bottom waters may have lower values if caused
    by natural conditions;
    ....
    (g)    pH: shall be normal for the waters in the
    area, which generally shall range between 6.0 and
    9.0 except that swamp waters may have a pH as low
    as 4.3 if it is the result of natural conditions[.]
    15A NCAC 2B .0211(3)(b), (g) (2013)
    122. Under DWR’s longstanding interpretation of the
    statutes and rules that it administers, the supplemental
    classification of swamp waters does not provide any
    additional protections to water bodies to which it is
    assigned; and low flow and velocity, low pH, low dissolved
    oxygen, and high tannins are not uses, standards,
    characteristics, or parameters of swamp waters that are
    required to be maintained or protected. (Reeder, Tr. Vol. 7
    pp. 1154-1157; Reeder, Tr. Vol. 4 pp. 653-657; Belnick, Tr.
    Vol. 4 pp. 523-524, 557-558; Reeder, Tr. Vol. 4 pp. 653-657;
    Belnick, Tr. Vol. 6 pp. 1059-1060)
    123. The CZR report states that with the proposed
    discharge, upper Blounts Creek may no longer exhibit
    intermittent flow, low dissolved oxygen concentrations,
    and high tannins. (Ex. R16 p. 10)
    124. The report also states that, with the proposed
    discharge, the use of the swamp stream sampling method
    may no longer be appropriate to evaluate benthic
    macroinvertebrates. (Ex. R16 p. 10)
    125. The report does not state that the swamp waters
    supplemental classification requires the preservation or
    maintenance of low dissolved oxygen, high tannins, low
    velocities, and low pH as contended by Petitioners. (Ex.
    - 66 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    R16 p. 10)
    126. Based on the evidence before it, DWR concluded that
    the Permit reasonably ensures compliance with all
    applicable water quality standards, including those
    applicable to upper Blounts Creek, which has a C primary
    classification and a Sw supplemental classification.
    (Alterations in original.)
    The superior court affirmed the ALJ’s final decision as to the swamp water
    classification issue. The superior court stated the issue as follows
    II.     Did the ALJ err in upholding DWR’s issuance of the
    Permit as reasonably ensuring compliance with:
    A.      The       swamp      waters     supplemental
    classification and antidegradation rule[.]
    The superior court addressed Petitioners’ swamp water claim as follows:
    North Carolina’s water quality regulations protect
    North Carolina’s surface waters by: (1) establishing
    surface water classifications based primarily on the “best
    uses” of surface waters, see 15A NCAC 02B .0101; 
    N.C. Gen. Stat. § 143-214.1
    (b); (2) establishing water quality
    standards that protect assigned uses of “primary
    classifications,” see, e.g., 15A NCAC 02B .0211 (water
    quality standards for Class C waters); and (3) assigning
    classifications to individual segments of surface waters
    throughout the State, see 15A NCAC 02B .0201 et seq.
    Some segments are also assigned “supplemental
    classifications,” which may alter water quality standards
    otherwise applicable. See 15 NCAC 02B .0101(e). The
    state antidegradation rule provides that “[e]xisting uses . .
    . and the water quality to protect such uses shall be
    protected by properly classifying surface waters and
    having standards sufficient to protect these uses.” 15A
    NCAC 02B .0201(b).
    - 67 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    The Permit authorizes Martin Marietta to discharge
    commingled stormwater and groundwater from two
    settling basins at its proposed quarry into the upper
    reaches of Blounts Creek. The parties do not dispute the
    primary classification and supplemental classifications
    assigned to Blounts Creek. Blounts Creek from its source
    to Herring Run (referred to by the parties as “upper
    Blounts Creek”) is assigned the primary classification of
    Class C and the supplemental classifications of Swamp
    Waters (“Sw”) and Nutrient Sensitive Waters (“NSW”).
    Petitioners argue that assignment of the swamp
    waters supplemental classification to upper Blounts Creek
    affixed “swamp water habitat” as a “special use” of that
    portion of the Creek; in turn, Petitioners argue, the
    antidegradation rule requires DWR to protect certain
    “natural characteristics” of swamp waters such as “low
    flow,” “low velocity,” and “dark color.”
    The ALJ rejected Petitioners’ argument, concluding
    that the swamp waters supplemental classification does
    not provide any additional protections to swamp waters
    beyond the water quality standards for protecting the uses
    of Class C waters. The ALJ concluded the only effect of the
    swamp waters supplemental classification is to make the
    water quality standards for pH and dissolved oxygen less
    stringent than otherwise required for Class C waters.
    Final Decision Conclusion of Law (“COL”) ¶ 93.
    The Court reviews the ALJ’s conclusions of law and
    statutory and regulatory interpretations de novo and
    findings of fact under the whole record test.
    “Swamp waters” are defined as “those waters which
    are classified by the Environmental Management
    Commission and which are topographically located so as to
    generally have very low velocities and other characteristics
    which are different from adjacent streams draining steeper
    topography,” 15A NCAC 02B .0202(62), or “waters which
    have low velocities and other natural characteristics which
    are different from adjacent streams.” 15A NCAC 02B
    .0101(e)(2). DWR interprets state water quality rules to
    require no additional protection for water segments
    assigned the swamp waters supplemental classification
    - 68 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    (beyond the protections required by the standards for the
    primary water quality classification, which in this case is
    Class C), an interpretation the ALJ considered de novo and
    upheld as reasonable and consistent with the plain
    language of North Carolina’s water quality standards.
    Final Decision COL ¶¶88-90, 98.
    The Court reviews this regulatory interpretation
    issue de novo and affirms the ALJ conclusion.
    Interpretation of administrative regulations
    “properly begins with the plain words” of the regulation.
    Cole v. N.C. Dep’t of Pub. Safety, 
    800 S.E.2d 708
    , 714 (N.C.
    Ct. App.), disc. rev. denied, 
    803 S.E.2d 156
     (2017). The
    Court’s de novo review of the antidegradation rule and
    rules governing the swamp waters supplemental
    classification shows that no “plain words” identify or
    protect a swamp waters “use” or identify or protect swamp
    waters “characteristics.”     15A NCAC 02B .0202(62),
    .0101(e)(2), .0211(6), .0211(14), .0220(5), .0220(12),
    .0301(c).
    The Court’s de novo review of the water quality rules
    as a whole indicates that if the North Carolina
    Environmental Management Commission (“EMC”) intends
    to protect a particular attribute or condition or use of
    surface waters, it does so in the text of its rules. With
    respect to uses of a surface water, the rules explicitly
    identify the uses associated with primary surface water
    classifications and, in some cases, supplemental
    classifications, and state narrative and numeric water
    quality standards to protect such uses. See, e.g., 15A
    NCAC 02B .0101(c)-(e), .0211(1), .0212(1), .0214(1), .216(1),
    .0218(1), .0219(1), .0220(1), .0221(1), .0222(1), .0231(a).
    There is no such identification of uses for the swamp
    waters supplemental classification and no effect on
    applicable water quality standards except to make less
    stringent the standards for pH and dissolved oxygen that
    would otherwise apply. The plain language and structure
    of the water quality rules indicates there is no intent to
    protect any alleged “use” particular to the swamp waters
    supplemental classification. See, e.g., Mangum v. Raleigh
    Bd. of Adjustment, 
    196 N.C. App. 249
    , 255, 
    674 S.E.2d 742
    ,

    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    747 (2009) (“One of the long-standing rules of
    interpretation and construction in this state is expressio
    unius est exclusio alterius, the expression of one thing is
    the exclusion of another.”).
    Similarly, with respect to characteristics of a water
    body, the rules show that the EMC knows how to protect a
    specific characteristic if it so desires. For example, the
    water quality rules establish explicit flow requirements for
    high quality waters. 15A NCAC 02B .0224(1)(v) (setting
    maximum volume of wastewater discharge into high
    quality waters). There is no text in the swamp waters
    supplemental classification rules (or elsewhere in the
    water quality rules) requiring protection of particular
    “swamp water characteristics.” With the exception of “low
    velocity,” the characteristics cited by Petitioners —
    “periods of low or no flow, low velocity, low pH, low
    dissolved oxygen, and high tannin levels” — do not appear
    in any water quality rule. References in the rules to “low
    velocity” pertain only to a quality that swamp waters
    “generally have,” 15A NCAC 02B .0202(62), not to a quality
    those waters must have. Significantly no rules protect or
    assure that waters with the swamp waters supplemental
    classification will have low velocity, periods of low or no
    flow, or high tannin levels. The Court is not vested with
    rule making authority. The water quality standards for pH
    and dissolved oxygen applicable to Class C waters are
    made less stringent for water bodies with the swamp
    waters supplemental classification, and this appears to the
    Court to be the only effect of that supplemental
    classification. 15A NCAC 02B .0211(3)(b), (g) (2013).
    Even if Petitioners’ interpretation of the swamp
    waters and antidegradation rules could be characterized as
    reasonable, DWR’s interpretation nonetheless is
    reasonable and is affirmed. The Court notes that, as found
    by the ALJ, and supported by substantial evidence in the
    record as a whole, DWR’s interpretation is longstanding
    and consistent with the plain language and the structure
    of the water quality rules. The Court gives deference to
    DWR’s interpretation that the water quality rules do not
    create special protections for characteristics such as “low
    - 70 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    flow, low velocity, and dark color,” or otherwise.
    The Court also notes that the state’s water quality
    rules provide a means by which the EMC may classify
    waters as High Quality Waters or classify unique and
    special surface waters of the state as Outstanding Resource
    Waters, and thereby provide a means of protecting certain
    characteristics of those waters that are not otherwise
    protected by water quality standards. 15A NCAC 02B
    .0225(a)(2). The record evidence does not show that
    Petitioners have sought such regulatory protections for
    Blounts Creek. 15A NCAC 02B .0225.
    The Court is not persuaded that PUD No. 1 v.
    Washington Department of Ecology, 
    511 U.S. 700
     (1994),
    supports Petitioners’ Swamp Waters Claim. Petitioners
    have not shown that there is any designated use associated
    with the “swamp waters” supplemental classification that
    is required to be maintained or protected under North
    Carolina’s water quality rules or otherwise.
    The Court has reviewed the Final Decision findings
    in relation to Petitioners’ Swamp Waters Claim, see, e.g,
    Final Decision FOF ¶¶119-126, 158-202, and based on its
    review of the whole record, the Court concludes that
    substantial evidence supports these findings.         These
    findings support the ALJ’s conclusion that Petitioners
    failed to carry their burden before OAH to prove DWR
    acted erroneously or arbitrarily or otherwise unlawfully in
    determining that the Permit reasonably ensures
    compliance with all applicable water quality standards,
    including the swamp waters supplemental classification
    and the state antidegradation rule.
    The Final Decision findings of fact and conclusions
    of law and holding that Petitioners failed to carry their
    burden and that the Permit reasonably ensures compliance
    with the swamp waters supplemental classification and the
    state antidegradation rule are affirmed and upheld.
    Petitioners do not challenge the facts as found by the ALJ or discussed by the
    superior court regarding swamp waters but rather argue “[t]he issue before the Court
    - 71 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    is one of law: does Blounts Creek’s classification as swamp waters protect the creek’s
    use as a unique habitat?” Petitioners contend that DEQ and the superior court
    interpreted the swamp water secondary classification as serving only “to weaken the
    creek’s protections, to allow for more pollution in Blounts Creek,” and if the
    classification were interpreted properly, the swamp waters classification “is like all
    other water classifications in North Carolina--it protects our creeks and rivers.”
    Petitioners further contend the swamp waters classification actually gives
    “additional protection for waterways that have special characteristics found in
    swamp waters and, as a result provides habitat for the fish, insects, and other
    animals that are well suited to that environment.” Thus, Petitioners argue that the
    secondary classification of swamp waters requires that the natural characteristics of
    swamp water to remain essentially unchanged and that DEQ’s “extreme
    interpretation” of the swamp waters classification as accepted by the ALJ and
    superior court, “does not provide any protection at all” and “only weakens . . .
    standards to allow for more pollution in Blounts Creek.”
    Martin Marietta contends that neither North Carolina law nor the Clean
    Water Act (“CWA”) require “‘natural’ conditions or characteristics” of a body of water
    to remain unchanged. Martin Marietta contends both state and federal law recognize
    the need to balance many interests and needs related to use of water and water

    Opinion of the Court
    quality, including public health, fish and wildlife, recreation, industry, and
    agriculture:
    The CWA requires each State to adopt and
    implement water quality standards, which “consist of the
    designated uses of the navigable waters involved and the
    water quality criteria for such waters based upon such
    uses.” 
    33 U.S.C.A. § 1313
    (c)(2)(A).
    Such standards shall be such as to protect the
    public health or welfare, enhance the quality
    of water and serve the purposes of this
    chapter. Such standards shall be established
    taking into consideration their use and value
    for public water supplies, propagation of fish
    and wildlife, recreational purposes, and
    agricultural, industrial, and other purposes,
    and also taking into consideration their use
    and value for navigation.
    
    33 U.S.C. § 1313
    (c)(2)(A) (emphasis added); see PUD
    No. 1, 511 U.S. at 704.
    Martin Marietta argues that
    [t]he very existence of the NPDES program refutes
    the theory that the CWA requires “natural” conditions or
    characteristics to remain unchanged.       The program
    provides for the issuance of permits that authorize
    discharge of wastewater into waters of the U.S. 
    33 U.S.C. § 1342
    . By introducing wastewater into a water body, the
    quality and quantity of the water in the receiving water
    body necessarily changes.
    Petitioners counter that DEQ has previously taken a position contrary to its
    position in this case as it “enforced against a polluter for not adequately protecting
    swamp waters” in the case of House of Raeford Farms, Inc. v. North Carolina
    Department of Environmental and Natural Resources, 
    242 N.C. App. 294

    - 73 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    911 (2015). Petitioners, quoting House of Raeford, contend that DEQ’s previous
    interpretation of the swamp waters classification was “that ‘the designated uses for
    the swamp waters . . . were deemed to be impaired.’” But House of Raeford does not
    contradict DEQ’s action in this case.
    In House of Raeford, DEQ investigated pollution in a creek, ultimately tracing
    the source to House of Raeford’s chicken processing facility.         See

    “the creek was just full of sludge from bank to bank and as
    far as the eye could see. It was an unbelievable site.”
    She testified the sludge was fresh because it was a
    light tan color: “It starts out looking like a milkshake and
    then as it decomposes, it gets darker because of the
    septicity.” The sludge adhered to the shorelines and was so
    thick on the surface of the water that it had formed ridges.
    The sludge was darker and thinner downstream from the
    House of Raeford.

    The superior court assessed a civil penalty of

    for causing or permitting waste to be discharged into or
    intermixed with the waters of the State in violation of the

    2B.0211(3)(c).
    Id. at 308, 774 S.E.2d at 920–21.
    House of Raeford addressed penalties for discharge of waste in violation of
    water quality standards in a manner not allowed by a permit and as such was an
    enforcement action for a water quality violation and not a proceeding for a permit
    application as presented by this case. See id., 
    242 N.C. App. 294
    , 
    774 S.E.2d 911

    North Carolina General Statute 143-215.1 recognizes that some discharges of waste
    which may otherwise not be allowed under applicable water quality standards may
    be allowed as provided by a permit:
    (a)    Activities for Which Permits Required. -- Except as
    provided in subsection (a6) of this section, no person shall

    N.C. Gen. Stat. § 143-215.1
     (2013) (emphasis added).
    We agree with Martin Marietta’s and DEQ’s interpretation of the law in that
    protection does not require that Blounts Creek remain entirely the same. Further,
    as the ALJ determined and the superior court affirmed, “DWR concluded that the
    Permit reasonably ensures compliance with all applicable water quality standards,
    including those applicable to upper Blounts Creek, which has a C primary
    classification and a Sw supplemental classification.” The findings of fact establish
    that the discharge of water into Blounts Creek may change some areas of the aquatic
    ecosystem and the changes will vary based upon distance from the outfall. For
    example, “there could be an increase in diversity and population of benthos near the
    proposed discharge outfalls because the discharge would lead to less stressful
    conditions.” The superior court acknowledges the discharge of water will change
    Blounts Creek, but keeping that change within acceptable limits is the purpose of the
    Permit. The Permit allows changes to the waters of Blounts Creek in accord with the
    limitations and provisions of the Permit, and those limitations are in accord with
    water quality standards applicable to Class C waters.        On de novo review of
    Petitioners’ issue “of law[,]” the ALJ and superior Court correctly concluded that
    DEQ’s issuance of the Permit did not violate water quality standards as applicable to
    “swamp waters” of Blounts Creek.
    - 77 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    E.    pH Water Quality Standards
    Much like the previous argument, Petitioners’ argument as to pH is based in
    large part on the characteristics of the secondary classification of swamp waters.
    Petitioners argue that the ALJ and superior court erred in approving the Permit
    because the wastewater will increase the pH in Blounts Creek to “to levels that do
    not occur naturally and are not characteristic of swamp waters.”            Essentially,
    Petitioners argue that the water quality standards for pH mandate that the swamp
    waters retain all of their characteristics, including low pH. Petitioners contend that
    [l]ow pH is a defining characteristic of swamp waters
    and is essential to maintaining habitat that is protected by
    the swamp waters classification. The permit allows Martin
    Marietta to increase pH in Blounts Creek to levels that do
    not occur naturally and are not characteristic of swamp
    waters. Under existing conditions, pH in Blounts Creek is
    as low as 4.37 and is almost always below 6.0. (T2 p 342:15-
    17, 357:8-358:15 [App. 24, 25-26]); (see also R p 1199). The
    permit allows Martin Marietta to increase pH to 8.5. (See
    R p 1589-1615).
    The issue before the Court is one of law: does the pH
    standard protect the normal, natural pH of Blounts Creek?
    Martin Marietta contends that if the regulations were interpreted and applied
    as Petitioners argue
    it would: (1) transform a straightforward water quality
    standard for pH into a byzantine and costly regulatory
    maze consisting of thousands of different sets of mandatory
    pH values or ranges; (2) force DWR to implement an
    expensive, time-consuming, and essentially unworkable
    site-by-site regulatory scheme to establish separate
    “normal” pH for each stream segment; and (3) create a new
    - 78 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    source of regulatory uncertainty, cause delay in permitting
    and enforcement, and impose the expense of sampling and
    analysis anytime there is a need to know the pH standard
    applicable to a water body segment. Such an exorbitantly
    resource-intensive agency activity is not feasible, not
    necessary, and not dictated by the language of the pH
    standard.
    The ALJ made the following findings regarding pH:
    106. The water quality standard governing pH for upper
    Blounts Creek requires that pH “shall be normal for the
    waters in the area, which generally shall range between 6.0
    and 9.0 except that swamp waters may have a pH as low
    as 4.3 if it is the result of natural conditions.” 15A NCAC
    2B .0211(3)(g) (2013).
    107. DWR’s longstanding interpretation of the pH
    standard for Class C water bodies is that the pH must be
    6.0 to 9.0; but if the water body has a supplemental
    classification of swamp waters (Sw), the lower range of pH
    can be extended down to 4.3 (if the low pH is caused by
    natural conditions). Thus, the pH standard for a C, Sw
    water body would be 4.3 to 9.0. (Belnick, Tr. Vol. 4 pp. 524,
    632; Reeder, Tr. Vol. 4 pp. 653-657)
    108. No evidence was presented that DWR has ever
    interpreted the pH standard differently.
    109. No evidence was presented that DWR has ever
    interpreted or applied the pH standard to require that low
    pH must be maintained in Sw waters. (Belnick, Tr. Vol. 4
    pp. 524, 631-632; Reeder, Tr. Vol. 4 pp. 653-657)
    110. DWR does not interpret the standard to require site-
    specific sampling and analysis. (Belnick, Tr. Vol. 4 p. 562)
    111. Rather the standard itself defines “normal” pH to be
    6.0 to 9.0 in Class C waters, with permissible lower values
    (down to 4.3) in Sw waters if the lower values are caused
    - 79 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    by natural conditions. (Reeder, Tr. Vol. 4 pp.653-657)
    112. DWR’s longstanding interpretation is also reflected
    in NPDES permits issued across the State and in DWR’s
    assessment of waters for impairment. (Reeder, Tr. Vol. 4
    pp. 653-657)
    113. Available data indicate that the existing pH in upper
    Blounts Creek ranges from approximately 4.5 downstream
    from the outfalls to approximately 5.3 to 6.5 at Dr. Bean’s
    upstream sampling site. (Ex. P12; Ex. P23)
    114. The expected pH of the discharge effluent is
    approximately 6.9; and the pH in upper Blounts Creek with
    the permitted discharge is expected to range from
    approximately 6.3to 6.9. (Ex. R1 p.4; Ex. P21)
    115. Dr. Bean agreed with the Kimley Horn report
    prediction that the pH of upper Blounts Creek would not
    exceed 6.94 at full discharge.10 (Ex. P12 p. 36)
    116. The Permit requires that the pH of the permitted
    discharge be within the range of 5.5 to 8.5. Thus, the pH
    of upper Blounts Creek with the permitted discharge is
    predicted and required to remain within the range of 4.3 to
    9.0. (Ex. R29)
    117. Petitioners’ attorneys conceded that the pH of
    neither the discharge nor the effluent would be in excess of
    9 or below 4.3. (Tr. Vol. 4 p. 657)
    118. Based on the evidence before it, DWR concluded that
    the Permit reasonably ensures compliance with the pH
    water quality standard.
    10   Dr. Eban Bean was a witness for Petitioners.
    - 80 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    The superior court affirmed the ALJ’s findings and conclusions as to pH, as
    follows:
    At the time the Permit was issued, the pH standard
    for Class C waters applicable to upper Blounts Creek read
    as follows:
    pH: shall be normal for the waters in the
    area, which generally shall range between 6.0
    and 9.0 except that swamp waters may have
    a pH as low as 4.3 if it is the result of natural
    conditions.
    15A NCAC 02B .0211(3)(g) (2013).
    In their pH Claim, Petitioners argue that the rule
    required DWR to undertake site-specific sampling to
    determine what “normal” pH is for the receiving waters in
    the area of the proposed discharge, which, in turn, must be
    maintained. Petitioners argue that: DWR did not
    determine “normal” pH for upper Blounts Creek; the
    Permit pH limit of 5.5 to 8.5 allows the permitted discharge
    to cause upper Blounts Creek to exceed its “normal” pH;
    and the Permit therefore fails to reasonably ensure
    compliance with the pH standard.
    DWR interprets the pH standard as setting a
    maximum allowable pH of 9.0 and a minimum allowable
    pH of 6.0, except that the lower limit may be as low as 4.3
    in swamp waters, if pH below 6.0 is the result of natural
    conditions. DWR interprets the rule as not requiring site-
    specific sampling or testing. Based on its interpretation of
    the pH rule, DWR established a Permit limit for pH of the
    discharge effluent of 5.5 to 8.5.
    The ALJ concluded that DWR’s interpretation is
    reasonable and consistent with the plain language of the
    rule, and rejected Petitioners’ pH claim because the
    Permit’s pH limits reasonably ensure compliance with the
    pH standard.
    The Court reviews the ALJ’s factual determinations
    under the whole record test and asserted legal errors and
    interpretation of rules de novo.
    The Court is not persuaded that the pH rule creates
    - 81 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    or requires a site-specific standard for pH in receiving
    waters.      First, the interpretation of administrative
    regulations “properly begins with the plain words” of the
    regulation. Cole, 
    800 S.E.2d at 714
    . The “plain words” of
    the pH rule do not require a site-specific standard or site-
    specific sampling to determine a site-specific standard.
    The rule states that pH “shall be normal for the waters in
    the area,” and then provides that: (a) “normal for the
    waters in the area” “generally shall range between 6.0 and
    9.0,” and (b) a lower pH may be allowed (to a minimum of
    4.3) “if it is the result of natural conditions.” DWR
    interprets the rule itself to define what “normal” pH is for
    a stream segment that has been assigned the
    classifications Class C-Sw: 6.0 to 9.0, or 4.3 to 9.0 if the
    lower pH results from natural conditions.
    Second, as noted in the Final Decision, this
    interpretation is supported by the EMC’s 2014 technical
    amendment, which deleted the words “generally shall”
    from the pH standard. 15A NCAC 02B .0211(14) (2015).
    This technical amendment further clarifies that “normal
    for waters in the area” is defined by the numerical range
    set forth in the text of the rule. Moreover, the current text
    of the pH rule is consistent with the language of other
    water quality standards that explicitly state the numeric
    limits required. See, e.g., 15A NCAC 02B .0211(3), (5), (6),
    (9), (11). The only exception to the applicable pH range is
    in swamp waters, where the lower limit may be decreased
    — made less stringent — if low pH is the result of natural
    conditions.
    Third, the state’s water quality standards make
    clear that site-specific standards are the exception, not the
    norm, and are explicitly set forth where they exist. E.g.,
    15A NCAC 02B .0110 (requiring site-specific strategies for
    waters providing habitat for federally listed threatened
    and endangered species), .0211(11) (allowing creation of
    site-specific standard for metals), .0226 (providing that
    “site-specific water quality standards may be granted by
    the Commission on a case-by- case basis”). No site-specific
    standards for pH are described or required in the water
    quality rules applicable here.
    - 82 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    Fourth, even if Petitioners’ proposed interpretation
    of the pH standard were reasonable, in reviewing agency
    regulatory interpretations, the Court agrees with the ALJ’s
    determination that DWR’s interpretation is reasonable and
    consistent with the plain language of the regulation. The
    Court accords deference to that interpretation.
    Based on the Court’s de novo interpretation of the
    pH rule, the Court upholds DWR’s interpretation of the pH
    rule and declines to accept Petitioners’ claim that the rule
    requires site-specific assessment.
    The Court has reviewed the Final Decision findings
    in relation to Petitioners’ pH Claim, see, e.g., FOF ¶¶90,
    104-118, 145-151, 164-170, and based on its review of the
    whole record, the Court concludes that substantial
    evidence supports these findings, and that Petitioners
    failed to carry their burden before OAH to prove DWR
    acted erroneously or arbitrarily or otherwise unlawfully in
    determining that the Permit reasonably ensures
    compliance with the pH standard.
    The Final Decision findings of fact and conclusions
    of law and holding that Petitioners failed to carry their
    burden and that the Permit reasonably ensures compliance
    with the pH standard are affirmed and upheld.
    The Superior Court correctly addressed each of the Petitioners’ arguments. As
    the ALJ and Superior Court determined, the DEQ’s interpretation of the pH rules is
    reasonable and consistent with the regulations. The regulations do not require that
    the pH of swamp waters stay the same as they currently are and that no new
    discharges be allowed if the discharge would change the pH. Again, the law requires
    the balancing of many interests and expertise in analyzing the conditions of the
    waters affected by each permit application. On de novo review of Petitioners’ issue
    - 83 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    “of law[,]” the ALJ and superior court correctly concluded that DEQ’s issuance of the
    Permit did not violate pH water quality standards of Blounts Creek.
    F.    Reopener Provision
    Petitioners last argue that the “required reopener provision does not authorize
    DWR to issue a permit expected to violate water quality standards.” (Original in all
    caps.) Petitioner notes that
    [f]or unexpected water quality standard violations
    that occur after a permit is issued, DWR has the authority
    to reopen and modify a permit—a condition that is
    memorialized in standard conditions for all discharge
    permits. See 15A N.C. Admin. Code 02H .0114(a) [App.
    140]; 
    40 C.F.R. §§ 122.41
    (a) and 122.41(f) [App. 105-6] (R
    p 1603). This standard condition has been referred to as a
    “reopener provision.”
    (Emphasis added.) Petitioners contend the superior court erred by determining that
    the reopener provision “can absolve the agency of its obligation to deny a permit
    without ensuring compliance with either the swamp waters classification or the pH
    water quality standard.”
    Martin Marietta argues that the premise of Petitioner’s argument is erroneous
    because “the Permit reasonably ensures compliance with and does not violate any
    water quality standards, and Petitioners failed to carry their burden of proof to show
    otherwise.”   As already noted, we agree.         Neither the ALJ nor superior court
    determined that a reopener provision can “absolve” DEQ of compliance with water
    quality standards. Instead, the ALJ determined the Permit reasonably ensures
    - 84 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    compliance with the water quality standards, and the superior court determined the
    Permit reasonably ensured compliance with all water quality standards except
    “biological integrity,” but we have reversed that conclusion.
    The Permit was issued based upon predictions of the expected impact of the
    discharge of wastewater into Blounts Creek, but if those predictions prove to be
    wrong, DEQ has authority to modify or revoke the Permit. To ensure compliance
    with water quality standards, the ALJ found the Permit requires monitoring of
    Blounts Creek after discharge of water from the quarry begins:
    145. On July 24, 2013, DWR issued the final NPDES
    Permit in the same form as it had been presented to the
    EPA. (Belnick, Tr. Vol. 6 pp. 1053-1054; Ex. R29; Ex. R27).
    146. The Permit terms include discharge controls,
    effluent and instream monitoring, and benthic biological
    monitoring requirements. (Ex. R29)
    147. Effluent monitoring requirements include flow, total
    suspended solids, total iron, turbidity, settleable solids,
    total nitrogen, total phosphorus, temperature, and pH.
    (Ex. R29 pp.3-4)
    148. The Permit also requires instream monitoring at two
    downstream stations (D1 and D2) for pH, salinity,
    temperature, and turbidity. (Ex. R29)
    149. The Permit requires benthic sampling at four
    locations, the results of which must be submitted at least
    six months prior to the expiration of the permit (which
    expires every five years). (Belnick, Tr. Vol. 6 pp. 1054-
    1055; Fleek, Tr. Vol. 7 pp. 1123-1128; Ex. R29)
    150.   The    benthic   monitoring          provision   requires
    - 85 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    submission of a sampling plan to DWR for approval prior
    to sampling, and requires compliance with DWR sampling
    protocols. (Fleek, Tr. Vol. 7 pp. 1123-1128; Ex. R29)
    In addition, the Permit requires Martin Marietta “to obtain other state authorizations
    for its proposed quarry” which also address “potential impacts on water quality,”
    including “a certification under Section 401 of the Clean Water Act and a consistency
    concurrence from the North Carolina Division of Coastal Management (“DCM”).” The
    ALJ order also found:
    153. On May 15, 2013, DWR issued Water Quality
    Certification DWQ #11-1013 (“401 Certification”) to
    Respondent-Intervenor. (Ex. MMM46)
    154. The 401 Certification requires, among other things:
    (a) that construction activities must follow best
    management practices “so that no violations of state water
    quality standards, statutes, or rules occur”; (b) a
    monitoring plan for some of the same concerns raised and
    addressed in the NPDES permit process, including:
    “measures to monitor physical and chemical stability of
    headwater streams to ensure that the project does not
    result in violation of water quality standards,” and an
    annual report summarizing the monitoring results; and (c)
    that Martin Marietta conduct the authorized activities
    “consistent with State water quality standards.” (Ex.
    MMM46 pp. 4-6)
    155. DWR is authorized to modify the 401 Certification,
    if needed, to ensure compliance. (Belnick, Tr. Vol. 6 pp.
    1064-1068; Ex. MMM46 p. 6)
    156. In February 2014, DCM issued Coastal
    Management Program Consistency Concurrence DCM
    #20120010 (“Coastal Consistency Concurrence”) that
    requires Respondent-Intervenor to, among other things: (a)
    - 86 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    coordinate with DCM to develop fisheries monitoring that
    will assess impacts of the proposed project on fish species
    and habitat in the Blounts Creek system; (b) coordinate
    with DCM to develop a monitoring protocol that will assess
    potential impacts of the proposed project on stream bank
    stability within the Blounts Creek system; (c) comply with
    the NPDES Permit and provide a copy of all benthic
    monitoring reports to DCM; and (d) comply with the 401
    Certification and provide a copy of all wetland hydrology
    monitoring reports to DCM. (Belnick, Tr. Vol. 6 pp. 1057-
    1059; Ex. R32 p. 2)
    157. DWR may revisit the NPDES Permit and modify or
    revoke it at any time based on information from the
    monitoring and reporting requirements of the Permit as
    well as information collected pursuant to the Coastal
    Consistency Concurrence and the 401 Certification.
    (Reeder, Tr. Vol. 7 pp. 1151-1153; Ex. R32; Belnick, Tr. Vol.
    6 pp. 1059; Ex. R32; Ex. R29)
    This Court addressed a similar argument regarding potential future water
    quality violations in Deep River Citizens’ Coalition v. North Carolina Department of
    Environment and Natural Resources, 
    165 N.C. App. 206
    , 
    598 S.E.2d 565
     (2004). The
    Petitioner argued the Environmental Management Commission (“EMC”) and trial
    court erred by determining the Randleman Dam and Reservoir project “would not
    violate certain water quality standards[,] specifically “water quality standards for
    chlorophyll a.” 
    Id. at 209
    , 
    598 S.E.2d at 567
    . Petitioners contended the computer
    models used by EMC to predict the effects of the project on chlorophyll a level were
    “flawed and unreliable.” 
    Id. at 212
    , 
    598 S.E.2d at 569
    . Although some models
    - 87 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    predicted chlorophyll levels within the applicable standard, other computer models
    predicted levels in excess. See 
    id.
     This Court noted that when
    the Director of the Division of Water Quality issued the 401
    Certification, he was aware of the potential for water
    quality standard violations and “specifically considered the
    existing Randleman Lake Water Supply Watershed
    Nutrient Management Strategy and the opportunity that
    the State would have to impose additional restrictions on
    nutrient sources in the event of actual or threatened water
    quality standard violations after the reservoir is
    constructed.” We agree with respondents that “no one will
    know precisely whether or to what extent exceedances . . .
    of the Standard will occur until construction of the dam and
    impoundment of the lake have been completed” but that
    mere “knowledge of the potential for exceedances . . . of the
    chlorophyll a standard was not sufficient to preclude
    DENR from issuing the 401 Certification.” The trial court
    therefore had before it substantial and competent evidence
    that, in the event water quality standards were actually
    threatened, the State could impose additional restrictions
    to avoid chlorophyll a violations. We conclude the trial
    court did not err in concluding that DENR provided
    reasonable assurance that the State’s water quality
    standards would not be violated by the proposed project.
    
    Id. at 213
    , 
    598 S.E.2d at 569
     (brackets omitted).
    Just as in Deep River, “no one will know precisely whether or to what extent”
    violations of various water quality standards, including standards not addressed in
    this opinion, may occur until after discharge of wastewater begins. 
    Id.
     The ALJ and
    superior court determined that the Permit reasonably ensures compliance with water
    quality standards, but the Permit requires specific monitoring and reports, and if a
    violation does occur, DEQ can modify or revoke the Permit to prevent further
    - 88 -
    SOUND RIVERS, INC. V. NC DEP’T OF ENVTL. QUALITY
    Opinion of the Court
    violations of water quality standards. The reopener provision in no way allows DEQ
    “to issue a permit expected to violate water quality standards” as Petitioner contends.
    This argument is without merit.
    IV.     Conclusion
    Ultimately, we affirm the superior court’s order as to the ALJ’s conclusions on
    compliance with pH standards and swamp water and reverse the superior court’s
    order as to the ALJ’s findings and conclusions on compliance with the biological
    integrity standards. As a practical matter, this means the ALJ correctly determined
    the Permit was properly and validly issued in accord with applicable regulations.

    I agree with the lead opinion’s rejection of Martin Marietta’s motion to dismiss.
    I further agree with the lead opinion’s conclusion that Petitioners demonstrated their
    rights were substantially prejudiced and are thus “person[s] aggrieved” within the
    meaning of Section 150B-23(a). And I agree with the lead opinion’s rejection of
    Petitioners’ argument pertaining to the reopener provision. Accordingly, I join these
    portions of the opinion in full.
    I also agree with the lead opinion that we must affirm the superior court’s order
    as to DEQ’s compliance with the swamp waters supplemental classification and the
    pH water quality standards. I further agree that we must reverse the superior court’s
    order as to the ALJ’s findings and conclusions regarding compliance with the
    biological integrity standard. I concur only in the result as to these issues, however,
    because I would decide them strictly on the basis of the deference owed DEQ’s
    interpretation of these regulations and the ALJ’s assessment of the record.
    As the lead opinion notes, the crux of the dispute is whether DEQ
    misinterpreted the biological integrity, swamp water, and pH regulations and, as a
    result, failed to engage in a sufficiently rigorous process.
    The scope of our review as to these issues is limited.         “[U]nless clearly
    erroneous or inconsistent with the regulation’s plain language[,]” we defer to “an

    173 N.C. App. 594
    , 598, 
    620 S.E.2d 14
    , 17 (2005). And, in assessing whether the factual
    record evinces compliance with the agency’s interpretation of its regulations, we are
    similarly constrained:
    [O]ur Supreme Court has made clear that even under our
    de novo standard, a court reviewing a question of law in a
    contested case is without authority to make new findings
    of fact. Under the whole record test, the reviewing court
    may not substitute its judgment for the ALJ’s as between
    two conflicting views, even though it could reasonably have
    reached a different result had it reviewed the matter de
    novo. Instead, we must examine all the record evidence—
    that which detracts from the ALJ’s findings and
    conclusions as well as that which tends to support them—
    to determine whether there is substantial evidence to
    justify the ALJ’s decision. Substantial evidence is relevant
    evidence a reasonable mind might accept as adequate to
    support a conclusion. We undertake this review with a high
    degree of deference because it is well established that ‘[i]n
    an administrative proceeding, it is the prerogative and
    duty of the ALJ, once all the evidence has been presented
    and considered, to determine the weight and sufficiency of
    the evidence and the credibility of the witnesses, to draw
    inferences from the facts, and to appraise conflicting and
    circumstantial evidence. The credibility of witnesses and
    the probative value of particular testimony are for the ALJ
    to determine, and the ALJ may accept or reject in whole or
    part the testimony of any witness.’

    These standards compel us to affirm the ALJ here. As discussed by the lead
    opinion, the agency’s interpretations of its own regulations in question are not clearly
    erroneous. Further, and again as chronicled by the lead opinion, there is evidence
    (much of it unchallenged by Petitioners and thus binding on our Court) a reasonable
    mind might accept as adequate to support the ALJ’s conclusions that DEQ complied
    with its long-standing regulatory interpretations in issuing this permit.
    I write separately because, pursuant to the controlling case law and standard
    of review, I would stop there. Whatever the merits of agency deference, it governs
    our deliberation and, coupled with the deference owed to the ALJ, decides this case.

    I agree with the majority opinion’s conclusion Petitioners demonstrated their
    rights were substantially prejudiced and are “person[s] aggrieved” within the
    meaning of Section 150B-23(a). I also concur in the majority opinion’s conclusions
    the trial court should be affirmed as to the ALJ’s conclusions on compliance with pH
    standards and swamp water.          I dissent, however, from the majority opinion’s
    conclusion the trial court erred by failing to give DWR’s interpretation of the
    “biological integrity standard” appropriate deference. Rather, I would affirm the trial
    court’s conclusion DWR did not demonstrate compliance with the biological integrity
    standard. As such, I would affirm the trial court’s Order in full including, specifically,
    the determination the ALJ’s Final Decision should be reversed and the Permit be
    revoked.
    The role of an appellate court in reviewing a trial court’s order
    affirming a decision by an administrative agency is two-fold. We
    must: (1) determine the appropriate standard of review and, when
    applicable, (2) determine whether the trial court properly applied
    this standard. De novo review is applied where an error of law is
    alleged.

    quality standards for bodies of water throughout North Carolina. See

    , -212. As the majority opinion detailed, Blounts Creek is classified as a
    Class C body of water with additional portions classified as Sw and NSW. Bodies of
    water that fall under Class C classification are subject to the water quality standards
    set forth in 15A N.C.A.C. 2B.0211. Notably, the best usage of Class C waters includes
    2
    SOUND RIVERS, INC. V. N.C. DEP’T OF ENVTL. QUALITY
    Hampson, J., concurring in part and dissenting in part.
    “aquatic life propagation and maintenance of biological integrity (including fishing
    and fish), wildlife, secondary recreation, agriculture[.]” 15A N.C.A.C. 2B.0211(1)
    (2018) (emphasis added).
    “Biological integrity” is defined as “the ability of an aquatic ecosystem to
    support and maintain a balanced and indigenous community of organisms having
    species composition, diversity, population densities and functional organization
    similar to that of reference conditions.” 15A N.C.A.C. 2B.0202(11) (2018). Therefore,
    as a Class C body of water, emissions into Blounts Creek must not impair the
    biological integrity of the water body. See 15A N.C.A.C. 2B.0211(2) (“Sources of water
    pollution that preclude any of these uses on either a short-term or long-term basis
    shall be considered to be violating a water quality standard[.]”).
    I would affirm the trial court’s conclusion DWR “did not ensure reasonable
    compliance with the biological integrity standard set forth in 15A N.C.A.C
    02B.0211(2), 0220(2) and 0202(11).” I recognize this Court affords deference to an
    agency’s interpretation of its own regulations; however, that necessarily means the
    agency actually has an interpretation of the regulation. In the present case, the
    Record does not indicate DWR had any interpretation for the “biological integrity
    standard” that it employed when evaluating the water quality standards prior to
    issuing the NPDES permit at issue to which deference is due. Instead—as the
    majority opinion notes and the ALJ found—final decision maker and Director of DWR

    SOUND RIVERS, INC. V. N.C. DEP’T OF ENVTL. QUALITY
    Hampson, J., concurring in part and dissenting in part.
    Mr. Reeder testified that he ‘[did not] know if there is such a thing’
    as a biological integrity analysis, and he ‘never really heard of
    such a thing’ in that there are no statutes or rules setting out
    numeric standards or explicit methods or metrics by which DWR
    must make a determination that an NPDES permit reasonably
    ensures compliance with the biological integrity standard.
    Further, “Mr. Fleek provided review, input, and opinions as to potential biological
    effects, Mr. Fleek was not asked to provide, nor did he provide, an opinion as to
    whether proposed discharge would comply with the biological integrity standard.”
    The majority opinion here relies on the fact that there “are no statutes or rules
    setting out numeric standards or explicit methods or metrics by which DWR must
    make a determination” in concluding that DWR was entitled to our deference in its
    interpretation of the biological integrity standard. Indeed, after the fact, DWR now
    contends it complied with the biological integrity standard because the “Standard
    Operating Procedure” encompasses the parameters defined in 15A N.C.A.C.
    2B.0202(11) as supporting biological integrity.               However, this ignores the
    requirement that the parameters supporting biological integrity be considered
    together and before the issuance of the NPDES permit.
    In this regard, unlike the majority, I see no conflict between the ALJ’s findings
    of fact and the trial court’s findings and legal conclusions. The ALJ documented the
    actions taken by DWR in reviewing the Permit Application but yet accepts that none
    of those actions were taken in the context of a specific analysis of biological integrity.
    This is not in tension with the trial court’s decision. To the contrary, the trial court
    4
    SOUND RIVERS, INC. V. N.C. DEP’T OF ENVTL. QUALITY
    Hampson, J., concurring in part and dissenting in part.
    determined, notwithstanding DWR’s efforts to retroactively justify its decision, the
    regulation is clear: in reviewing a Permit Application, DWR is required to undertake
    sufficient analysis to ensure the biological integrity standard (as that term is defined)
    is met.11 It is just as clear on this Record, DWR did not undertake that analysis in
    reviewing the application.12 Thus, as the trial court concluded, DWR was not entitled
    to any deference in how it interpreted or analyzed a biological integrity standard that
    it failed to interpret or analyze.           Put another way: interpreting the regulation
    requiring DWR to reasonably ensure any discharge would not preclude the protected
    use of Blounts Creek to maintain its biological integrity in a manner that allows DWR
    to functionally ignore that very requirement during the permitting process would be
    11 I do not read the trial court’s decision as declaring every aspect of the biological integrity
    standard, its component parts, or the specific measurements required to be clear and unambiguous
    and not subject to any deference in its interpretation and application. Rather, I read the trial court’s
    decision as concluding simply that the regulation expressly and clearly requires DWR, in reviewing
    an application, to specifically undertake steps to ensure compliance with the biological integrity
    standard, including analysis of the definitional components of that standard. It is no stretch to further
    conclude that in order to ascertain whether or not a proposed application would preclude “the ability
    of an aquatic ecosystem to support and maintain a balanced and indigenous community of organisms
    having species composition, diversity, population densities and functional organization similar to that
    of reference conditions[,]” 15A N.C.A.C. 2B.0202(11) (2018), an affirmative determination of the
    “reference conditions” is necessarily required.
    12 Indeed, on this Record, there is reason to believe had DWR contemporaneously conducted
    any type of analysis envisioned by the regulation, it may well have reached a different conclusion. For
    example, the Record reflects email correspondence in which Mr. Fleek notes:
    The biota presently found in the Blounts Creek system is adapted to
    intermittent flow, low pH, and low dissolved oxygen. The proposed discharge
    will alter the natural physcio-chemcial [sic] parameters of this system . . . . As
    such, many of the taxa currently found in this system which are adapted to the
    natural condition will be replaced by taxa that are adapted to more permanent
    flows, higher pH, and higher dissolved oxygen levels. The taxa that are
    naturally occurring to this type of stream system will be replaced with taxa
    that are not typical to this type of system. . . . These types of streams, and the
    taxa which inhabit them, are not normally found in North Carolina’s coastal
    plain.

    Hampson, J., concurring in part and dissenting in part.
    plainly inconsistent with the plain language of the regulation and, thus, DWR is not
    entitled to any deference in such an interpretation. Pamlico Marine Co., Inc. v. N. C.
    Dep’t of Natural Resources, 
    80 N.C. App. 201
    , 206, 
    341 S.E.2d 108

    (“Ordinarily, an administrative agency’s interpretation of its own regulation is to be
    given due deference by the courts unless it is plainly erroneous or inconsistent with
    the regulation.”(citation omitted)).
    I therefore disagree with the majority opinion and would affirm the trial court’s
    conclusion DWR did not reasonably demonstrate compliance with the biological
    integrity standard. Accordingly, I would also affirm the trial court’s Order requiring
    the Permit be revoked.
