    TRAXLER, Circuit Judge:
    Virginia certified under Section 401 of the Clean Water Act that it had reasonable
    assurance that certain activities regarding the construction of a natural gas pipeline would
    not degrade the state’s water. Several environmental groups, individuals, and other
    entities petition for review. Concluding that Virginia’s issuance of the certification was
    not arbitrary and capricious, we deny the petition for review.
    I.
    A.     The Project
    The Mountain Valley Pipeline Project (the “Project”) is a proposed interstate
    natural gas transmission pipeline that will be approximately 303 miles long and 42 inches
    in diameter and will transport natural gas from Wetzel County, West Virginia, to
    Pittsylvania County, Virginia. Much of the Project crosses topography with steep slopes
    and areas that are susceptible to landslides. Approximately 106 miles of the pipeline will
    be located in Virginia, and constructing the pipeline requires 385 stream crossings and
    144 wetland crossings in the Commonwealth.
    Mountain Valley Pipeline, LLC (“MVP”) proposes to construct and operate the
    pipeline in Virginia and West Virginia. 1 MVP generally would use a 125-foot-wide
    construction right-of-way in uplands and a 75-foot-wide right-of-way through wetlands.
    MVP would retain a 50-foot right-of-way permanently to operate the pipeline. For
    1
    Equitrans, L.P. also applied to construct and operate a portion of the
    pipeline that would provide service from western Pennsylvania and interconnect with the
    Project in Wetzel County, West Virginia. That portion of the pipeline is not a subject of
    the petition for review before us.
    4
    overland construction, MVP would generally need to clear the land of trees and
    vegetation, then dig a trench of up to nine feet in depth, fracturing and blasting rock
    where necessary. Waterbody crossings would be dry open-cut crossings; MVP would
    temporarily divert the water from the construction area and bury the pipeline two to four
    feet below the streambed.
    B.    Federal Statutes and Agencies
    The Natural Gas Act (“NGA”) requires that a party seeking to build or operate a
    natural gas pipeline must obtain authorization from the Federal Energy Regulatory
    Commission (“FERC”) in the form of a “certificate of public convenience and necessity.”
    The NGA and its implementing regulations set out the process for obtaining such a
    certificate. See 
    15 U.S.C. § 717
     et seq.; 
    18 C.F.R. § 157.1
     et seq.; see generally East
    Tenn. Nat. Gas. Co. v. Sage, 
    361 F.3d 808
    , 818 (4th Cir. 2004).
    When FERC receives an application for a certificate of public convenience and
    necessity, it undertakes review of the environmental impacts of the proposed project
    under the NGA and under the National Environmental Policy Act (“NEPA”), 
    42 U.S.C. §§ 4321
     et seq., usually by accepting input from the public and producing an
    environmental impact statement (“EIS”).         FERC serves as the “lead agency,”
    coordinating the needed governmental authorizations, see 15 U.S.C. § 717n(b), including
    the one central to this case, Virginia’s state water-quality certification under the Clean
    Water Act (“CWA”).
    NEPA sets out the procedures FERC must employ in considering the
    environmental impacts of agency actions. See Robertson v. Methow Valley Citizens
    5
    Council, 
    490 U.S. 332
    , 350 (1989).       Council on Environmental Quality regulations
    require FERC to draft an EIS in stages, first preparing a draft and inviting public
    comment thereon, then considering the comments and responding to them, possibly by
    modifying its analysis. See 
    40 C.F.R. §§ 1503.1
    (a), 1503.4(a). In this way, the draft and
    the receipt of comments serve as a “springboard for public comment.” National Comm.
    for the New River, Inc. v. FERC, 
    373 F.3d 1323
    , 1328 (D.C. Cir. 2004) (internal
    quotation marks omitted).
    Because construction of the Project would involve discharge of dredged and fill
    materials into wetlands and waterways, MVP needed not only a certificate of public
    convenience and necessity from FERC, but also approval from the U.S. Army Corps of
    Engineers (the “Corps”) under Section 404 of the CWA. See 
    33 U.S.C. § 1344
    (a); AES
    Sparrows Point LNG, LLC v. Wilson, 
    589 F.3d 721
    , 724 (4th Cir. 2009). Section 404
    approval from the Corps may come in the form of an issuance of individual permits or the
    Corps’ verification of the coverage “within the scope of an existing general permit, which
    acts as a standing authorization for developers to undertake an entire category of
    activities deemed to create only minimal environmental impact.” Crutchfield v. County
    of Hanover, Va., 
    325 F.3d 211
    , 214 (4th Cir. 2003) (citing 
    33 U.S.C. § 1344
    (e); 
    33 C.F.R. §§ 320.1
    , 330.1(b)-(c)). 2
    2
    “Activities falling within the scope of [a nationwide permit] are
    automatically authorized without any individualized inquiry, although preconstruction
    notification of the Corps is required in some cases.” Crutchfield v. County of Hanover,
    Va., 
    325 F.3d 211
    , 214 (4th Cir. 2003) (citing 
    33 C.F.R. § 330.1
    (e)). “In cases where
    preconstruction notification is required, the Corps will verify the applicability of the

    6
    The NGA largely preempts environmental regulation of interstate natural gas
    pipelines by states. See AES Sparrows Point LNG, LLC v. Smith, 
    527 F.3d 120
    , 125-26
    (4th Cir. 2008).    However, it does “allow[] states to participate in environmental
    regulation of [pipelines] under three federal statutes: the Clean Air Act, the Coastal Zone
    Management Act, and the Clean Water Act.”            Delaware Riverkeeper Network v.
    Secretary Pa. Dep’t of Envtl. Prot., 
    833 F.3d 360
    , 368 (3d Cir. 2016) (citing 15 U.S.C. §
    717b(d)).
    The state action challenged in the petition before us was taken pursuant to Section
    401 of the Clean Water Act. The relevant language provides that “[a]ny applicant for a
    Federal license or permit to conduct any activity . . . which may result in any discharge
    into the navigable waters” must seek “a certification from the State in which the
    discharge originates . . . that any such discharge will comply with the applicable
    provisions” of the CWA. 
    33 U.S.C. § 1341
    (a)(1). It provides that “[n]o license or permit
    shall be granted if certification has been denied by the State,” but, if a state “fails or
    refuses to act on a request for certification, within a reasonable period of time (which
    shall not exceed one year) after receipt of such request, the certification requirements of
    this subsection shall be waived.” 
    Id.
     (emphasis added). Under the CWA’s implementing
    regulations, the State also has the option of granting the certification based on certain
    conditions. See 
    33 U.S.C. § 1341
    (d); 
    40 C.F.R. § 121.2
    (a)(4); PUD No. 1 of Jefferson
    [nationwide permit] to the proposed activity.”

    33 C.F.R. § 330.1
    (e)(2)).
    7
    Cty. v. Washington Dep’t of Ecology, 
    511 U.S. 700
    , 712 (1994). Accordingly, a state
    receiving a Section 401 application has four options in total: it may grant a certificate
    without imposing any additional conditions; grant it with additional conditions; deny it;
    or waive its right to participate in the process. See Delaware Riverkeeper Network, 833
    F.3d at 376 (noting states’ options to deny certificate or to waive right to participate); see
    also S.D. Warren Co. v. Maine Bd. of Envtl. Prot., 
    547 U.S. 370
    , 380 (2006) (“Section
    401 . . . was meant to continue the authority of the State to act to deny a permit and
    thereby prevent a Federal license or permit from issuing to a discharge source within such
    State.” (alterations and internal quotation marks omitted)).        If the state grants the
    certificate – whether with or without conditions – the certification must contain “[a]
    statement that there is a reasonable assurance that the activity will be conducted in a
    manner which will not violate applicable water quality standards.”                
    40 C.F.R. § 121.2
    (a)(3) (emphasis added); see PUD No. 1 of Jefferson Cty., 
    511 U.S. at 712
    .
    As for appellate review of such a state certificate, § 717r of the NGA provides:
    The United States Court of Appeals for the circuit in which a facility
    subject to . . . [15 U.S.C. § 717f] is proposed to be constructed, expanded,
    or operated shall have original and exclusive jurisdiction over any civil
    action for the review of an order or action of a . . . State administrative
    agency acting pursuant to Federal law to issue, condition, or deny any
    permit, license, concurrence, or approval . . . required under Federal law.
    15 U.S.C. § 717r(d)(1). It is undisputed here that the Project is subject to 15 U.S.C.
    § 717f.
    C.     Virginia Agencies and Virginia Law Regarding Issuance of Section 401
    Certificates
    8
    Under Virginia law, the State Water Control Board (the “Board”) possesses broad
    authority concerning permitting and regulatory matters that affect water quality in
    Virginia, including authority over Section 401 certifications. See Va. Code § 62.1-44.15.
    During the events in question, Virginia law provided that, “[i]ssuance of a Virginia Water
    Protection Permit shall constitute the certification required under § 401 of the Clean
    Water Act.” Va. Code § 62.1-44.15:20(D). 3 Pursuant to the Virginia Water Protection
    Program (the “VWP Program”), the Board, after consulting with appropriate agencies
    and accepting and considering public comment, may issue a VWP permit “if it has
    determined that the proposed activity is consistent with the provisions of the Clean Water
    Act and the State Water Control Law and will protect instream beneficial uses.” Va.
    Code § 62.1-44.15:20(B). And the Board may certify a nationwide Corps permit as
    3
    On March 30, 2018, the Virginia legislature amended the statute, adding the
    emphasized language:
    Issuance of a Virginia Water Protection Permit shall constitute the
    certification required under § 401 of the Clean Water Act, except for any
    applicant to the Federal Energy Regulatory Commission for a certificate of
    public convenience and necessity pursuant to § 7c of the federal Natural
    Gas Act (15 U.S.C. § 717f(c)) to construct any natural gas transmission
    pipeline greater than 36 inches inside diameter, in which case issuance of a
    Virginia Water Protection Permit pursuant to this article and a
    certification issued pursuant to Article 2.6 (§ 62.1–44.15:80 et seq.) shall
    together constitute the certification required under § 401 of the federal
    Clean Water Act.

    meeting these requirements so long as the permit meets specified criteria. 4 See 9 Va.
    Admin. Code 25-210-130(H).
    The Virginia Department of Environmental Quality (“DEQ”) serves as the Board’s
    staff, and the Board may assign DEQ tasks and delegate DEQ the authority to make
    decisions. See Va. Code § 62.1-44.14. We will refer to the Board and DEQ together as
    “the State Agencies.”
    D.    2017 Guidance Document
    Until recently, it was only through the above-described process that DEQ issued
    its water-quality certificates for linear utility projects, including pipeline projects.
    However, in May 2017, as a result of comments from interested parties concerning the
    4
    Those criteria are met when the nationwide certificate and certification
    conditions:
    1.    Require that wetland or stream impacts be avoided and minimized to
    the maximum extent practicable;
    2.      Prohibit impacts that cause or contribute to a significant impairment
    of state waters or fish and wildlife resources;
    3.     Require compensatory mitigation sufficient to achieve no net loss of
    existing wetland acreage and functions or stream functions and water
    quality benefits; and
    4.    Require that compensatory mitigation for unavoidable wetland
    impacts be provided in accordance with 9 [Va. Admin. Code] § 25-210-
    116.
    5.     Require that compensatory mitigation for unavoidable stream
    impacts be provided in accordance with 9 [Va. Admin. Code] § 25-210-
    116, including but not limited to an analysis of stream impacts utilizing a
    stream impact assessment methodology approved by the board.
    
    9 Va. Admin. Code § 25-210-130
    (H).
    10
    Project, DEQ came to the conclusion that there was an analytical gap in the Rule 401
    certification process. Namely, while VWP Permit coverage addresses the impacts caused
    to wetlands and streams by activities conducted in wetlands and streams, see Ohio Valley
    Envtl. Coal. v. Aracoma Coal Co., 
    556 F.3d 177
    , 194 (4th Cir. 2009), it does not account
    for activities occurring in upland areas that could also result in discharges into state
    waters or otherwise affect Virginia’s water quality. See J.A. 100 (“The permits issued by
    the VWP program and the permits issued by the Corps only address the impacts caused to
    wetlands and streams by excavating in a wetland, draining or significantly altering
    wetland acreage or function, filling or dumping in a stream or wetland, or permanently
    flooding or impounding a wetland area or stream.          However, the conditions and
    requirements of these permits do not cover activities in upland areas, outside of wetlands
    and streams, which may result in a discharge to state waters or otherwise cause or
    contribute to an exceedance of Virginia’s Water Quality Standards.”).
    In recognition of this gap, DEQ recently issued its “2017 Guidance Document,”
    establishing a process by which, as part of the 401 certification process, DEQ can review
    these potential effects from upland activities involved in a natural gas infrastructure
    project. See Va. Dep’t of Envtl. Quality, Guidance Memo No. GM17-2003, Interstate
    Natural Gas Infrastructure Projects – Procedures for Evaluating and Developing
    Additional Conditions for Section 401 Water Quality Certification Pursuant to 
    33 USC § 1341
     (May 19, 2017). It provides that DEQ may decide to seek additional information
    from pipeline applicants concerning upland activity that “may have the potential to affect
    water quality.” 
    Id. at 3
    . And it states that DEQ may recommend to the Board the
    11
    imposition of conditions on upland activities that are in addition to the conditions already
    imposed by or through the VWP Permit Program, the Corps, or FERC. See 
    id.
    E.     Virginia’s Water Quality Standards and Water-Protection Laws
    “Under the CWA, states have the primary role in promulgating water quality
    standards.” Piney Run Preservation Ass’n v. County Comm’rs of Carroll Cty., 
    268 F.3d 255
    , 265 n.9 (4th Cir. 2001). To do so, a state begins by identifying the uses for which
    the water will be protected; then, the state determines the level of water quality needed to
    protect the water for those uses. See NRDC v. EPA, 
    16 F.3d 1395
    , 1400 (4th Cir. 1993).
    Two aspects of Virginia’s water-quality policy are relevant here: its general narrative
    water-quality criterion and its antidegradation policy.
    Virginia’s water-quality criterion requires that “State waters . . . shall be free from
    substances attributable to . . . waste in concentrations, amounts, or combinations which
    contravene established standards or interfere directly or indirectly with designated uses of
    such water or which are inimical or harmful to human, animal, plant, or aquatic life.” 
    9 Va. Admin. Code § 25-260-20
    (A).           The criteria specify that any substance “that
    produce[s] . . . turbidity” is a substance to be controlled. 
    Id.
     “Turbidity” refers to a
    measure of suspended solids in a water body, such as sediment.
    By its terms, Virginia’s antidegradation policy “shall be applied whenever any
    activity is proposed that has the potential to affect existing surface water quality.” 5 
    9 Va. 5
    As the Supreme Court explained in PUD No. 1 of Jefferson County:
    (Continued)
    12
    Admin. Code § 25-260-30(A). The policy divides the state’s waters into three tiers and
    provides different levels of protection for each tier. See 
    9 Va. Admin. Code § 25-260
    -
    30(A). Tier 3 encompasses waters designated as “exceptional”; these waters “shall be
    maintained and protected to prevent permanent or long-term degradation or impairment.”
    
    9 Va. Admin. Code § 25-260-30
    (A)(3)(b)(1). The policy specifically provides that “[n]o
    new, additional, or increased discharge of sewage, industrial wastes or other pollution
    into [Tier 3 waters] shall be allowed.” 
    9 Va. Admin. Code § 25-260-30
    (A)(3)(b)(2).
    However, “[a]ctivities causing temporary sources of pollution may be allowed in [Tier 3
    waters] even if degradation may be expected to temporarily occur provided that after a
    minimal period of time the waters are returned or restored to conditions equal to or better
    than those existing just prior to the temporary source of pollution.” 
    9 Va. Admin. Code § 25-260-30
    (A)(3)(b)(3).
    Tier 2 encompasses waters that “exceed water quality standards.” 
    9 Va. Admin. Code § 25-260-30
    (A)(2). The quality of such waters “shall be maintained and protected
    When the Clean Water Act was enacted in 1972, the water quality standards
    of all 50 States had antidegradation provisions. These provisions were
    required by federal law. By providing in 1972 that existing state water
    quality standards would remain in force until revised, the Clean Water Act
    ensured that the States would continue their antidegradation programs.
    EPA has consistently required that revised state standards incorporate an
    antidegradation policy. And, in 1987, Congress explicitly recognized the
    existence of an “antidegradation policy established under [§ 303].” §
    1313(d)(4)(B).
    PUD No. 1 of Jefferson Cty. v. Washington Dep’t of Ecology, 
    511 U.S. 700
    , 718 (1994)
    (citations omitted).
    13
    unless the board finds . . . that allowing lower water quality is necessary to accommodate
    important economic or social development in the area in which the waters are located.” 
    9 Va. Admin. Code § 25-260-30
    (A)(2).
    Finally, Tier 1 encompasses all waters that do not qualify as Tier 3 or Tier 2. For
    those waters, “existing instream water uses and the level of water quality necessary to
    protect the existing uses shall be maintained and protected.” 
    9 Va. Admin. Code § 25
    -
    260-30(A)(1).
    Virginia generally protects its water from impacts from upland construction-
    related activities through the National Pollutant Discharge Elimination System
    (“NPDES”) permits issued by Virginia under CWA section 402. See 
    33 U.S.C. § 1342
    .
    In particular, it utilizes its Virginia Pollutant Discharge Elimination System (“VPDES”)
    Program and, more specifically, its General VPDES Permit for Discharges of Stormwater
    from Construction Activities (the “Construction General Permit”). 
    9 Va. Admin. Code § 25-880-70
     Part II. That permit, in turn, incorporates the requirements of two other state
    laws, the Virginia Stormwater Management (“VSM”) Law, Va. Code § 62.1-44.15:24 et
    seq., and the Virginia Erosion and Sediment Control (“VESC”) Law, Va. Code § 62.1-
    44.15:51, et seq., which we will discuss in more detail ahead.
    Virginia’s regulatory scheme is a little different when the construction project in
    question is a natural gas pipeline. That is because the CWA exempts natural gas pipeline
    construction projects from regulation. See 
    33 U.S.C. § 1342
    (l)(2). Still, Virginia is able
    to impose the same substantive requirements on natural gas pipeline projects through its
    Annual Standards and Specifications (“AS&S”) Program.             See Va. Code § 62.1-
    14
    44.15:55(D). That program requires the project developer to submit annual standards and
    specifications for DEQ’s review and approval, thereby ensuring that projects will meet
    the same requirements that would apply were they covered by the Virginia Construction
    General Permit. See 
    9 Va. Admin. Code § 25-870-170
    (A). However, once DEQ has
    approved a developer’s annual standards and specifications as satisfying the requirements
    of the VSM and VESC, the entity generally need not submit site-specific VSM and
    VESC plans to DEQ for approval. See Va. Code § 62.1-44.15:55(D). In this way,
    projects become more self-regulating.
    II.
    MVP filed its application for a certificate of public convenience and necessity with
    FERC on October 23, 2015.
    A.     FERC
    As the NGA required, see 15 U.S.C. § 717n(b), FERC acted as the lead agency in
    preparing an EIS for the Project. FERC first issued a draft EIS in September 2016. Then
    during the 90-day period that followed, FERC conducted seven public meetings and
    received 1,237 written comments (many of which were from DEQ). Some of DEQ’s
    suggestions included adjusting the Project route, requiring a revised Karst Mitigation
    Plan, creating an Acid Soil Mitigation Plan, revising the Blasting Plan, and adopting
    various measures to reduce erosion and the introduction of sediment into the water.
    FERC’s final EIS, issued in June 2017, incorporated many of the suggestions DEQ had
    offered.
    15
    The EIS recognized that many aspects of the Project created the potential to
    negatively impact affected waters. With regard to upland construction activities, the EIS
    observed:
    The clearing and grading of stream banks could expose soil to
    erosional forces and would reduce riparian vegetation along the cleared
    section of the waterbody. The use of heavy equipment for construction
    could cause compaction of near-surface soils, an effect that could result in
    increased runoff into surface waters in the immediate vicinity of the
    proposed construction right-of-way. Increased surface runoff could
    transport sediment into surface waters, resulting in increased turbidity
    levels and increased sedimentation rates in the receiving waterbody.
    Disturbances to stream channels and stream banks could also increase the
    likelihood of scour after construction.
    J.A. 771.   The EIS stated that “[i]n order to limit impacts on riparian zones, the
    Applicants would follow measures outlined in its Procedures.” 6 J.A. 771.
    The EIS also recognized that flooding during construction was a potential concern.
    The EIS stated:
    To minimize or prevent impacts resulting from flash flooding during
    construction, the Applicants would remove any equipment or loose material
    from the affected area prior to any anticipated significant rain event.
    Additionally, the Applicants would implement erosion and sedimentation
    6
    The EIS explained:
    These measures allow a riparian strip at least 25 feet wide to permanently
    revegetate with native plant species across the entire construction right-of-
    way. A corridor centered on the pipeline and up to 10 feet wide may be
    cleared at a frequency necessary to maintain the 10-foot corridor in an
    herbaceous state; and trees that are located within 15 feet of the pipeline
    may be cut and removed from the permanent right-of-way. In addition, the
    riparian areas that are between HDD entry and exit point are not cleared
    during construction or mowed during operations.
    J.A. 771.
    16
    control measures, such as installing trench breakers and water bars to
    inhibit water flow along the trench and right-of-way. Upon completion of
    construction, the Applicants would restore the ground surface as closely as
    practicable to original contours and re-establish vegetation to facilitate
    restoration of pre-construction overland flow.
    J.A. 772. In the end, however, regarding construction of the Project that implementation
    of the various recommendations FERC had made and the plans MVP had agreed to
    follow, the EIS concluded:
    No long-term or significant impacts on surface waters are anticipated
    as a result of the projects, because Mountain Valley and Equitrans would
    not permanently affect the designated water uses, they would bury the
    pipeline beneath the bed of all waterbodies, implement erosion and
    sedimentation controls, adhere to crossing guidelines in their Procedures,
    and restore the streambanks and streambed contours as close as practical to
    pre-construction conditions. Temporary impacts would be avoided or
    minimized through the implementation of our recommendations . . . and
    various plans.
    J.A. 775.
    In October 2017, FERC issued a certificate of public convenience and necessity
    for the construction of the Project.      The certificate includes 37 “Environmental
    Conditions,” many of which reflect DEQ’s input. 7 FERC noted that MVP “committed to
    use specialized construction techniques on steep slopes, including cut-and-fill and two-
    tone grading, to minimize adverse effects.” J.A. 558. FERC also noted that MVP had
    developed a Landslide Mitigation Plan and FERC required that MVP revise the plan “to
    outline construction measures to be used when crossing steep slopes at angles
    7
    FERC’s issuance of the certificate is the subject of a petition for review
    pending in the Court of Appeals for the D.C. Circuit. FERC’s issuance of the certificate
    is not a subject of the petition before us.
    17
    perpendicular to contours and to include a more robust monitoring program.” J.A. 558.
    As for the concern that “slope failures will cause instream sedimentation,” FERC also
    noted that MVP had “agreed to follow the measures outlined in [FERC’s] Upland
    Erosion Control, Revegetation, and Maintenance Plan . . . and its Wetland and
    Waterbody Construction and Mitigation Procedures, which include erosion controls to
    prevent sedimentation into waterbodies.” J.A. 558. FERC acknowledged that “these
    plans cannot fully prevent sedimentation, but would provide adequate protections by
    reducing sedimentation into streams and reducing the potential for slope failures.” J.A.
    558.
    Also, “[t]o minimize potential impacts on karst related groundwater through
    construction associated sedimentation and runoff, [MVP] will implement the erosion
    control measures outlined in [FERC’s] Plan and its Karst-specific Erosion and Sediment
    Control Plan.”    J.A. 566.    Additionally, “to minimize the potential for hazardous
    materials leaking from construction equipment to contaminate groundwater, [MVP] will
    implement the measures outlined in its Stormwater Pollution Prevention Plan (SWPP
    Plan); Spill, Prevention, Control, and Countermeasures Plan (SPCC Plan); and
    Unanticipated Discovery of Contamination Plan for Construction Activities in West
    Virginia and Virginia.” J.A. 566.
    FERC’s certificate noted that, with regard to streams crossed by the Project, FERC
    was taking into consideration not only the sedimentation that would be produced from the
    crossing itself, but also the sedimentation that would result from runoff from construction
    workplaces. FERC noted that the stream crossings would “result in temporary (less than
    18
    4 days) and localized (for a distance of only a few hundred feet of the crossing) increases
    in turbidity downstream of construction, but the magnitude of this increase is minimal
    compared to increased turbidity associated with natural runoff events.” J.A. 569. FERC
    added that “[o]nce construction is complete, [MVP] will stabilize and restore streambeds
    and banks consistent with the Wetland and Waterbody Construction and Mitigation
    Procedures.” J.A. 569.
    In addition to all the measures FERC specifically required, FERC noted that the
    Corps and various state agencies “have the opportunity to impose conditions to protect
    water quality pursuant to sections 401 and 404 of the Clean Water Act.” J.A. 570. FERC
    emphasized that “[t]he applicants must obtain all necessary federal and state permits and
    authorizations, including the water quality certifications, prior to receiving [FERC]
    authorization to commence construction.” J.A. 570. FERC specifically concluded:
    Based on [FERC] staff’s experience with pipeline construction, and
    [MVP’s] commitment to cross waterbodies via dry-ditch methods,
    adherence to the measures in [FERC’s] Plan and Procedures, [MVP’s]
    proposal to conduct a stream monitoring plan, and use of [FERC’s] third-
    party compliance program, we determine that impacts on waterbodies due
    to sedimentation will be effectively minimized.
    J.A. 567.
    FERC’s certificate provided that MVP “must receive written authorization from
    the Director of OEP [Office of Energy Projects] before commencing construction of any
    project facilities.” J.A. 628 (emphasis omitted). Finally, as is relevant here, the face of
    the certificate explained FERC’s flexibility to deal with unforeseen contingencies with
    the potential to affect the environment:
    19
    The Director of OEP, or the Director’s designee, has delegated authority to
    address any requests for approvals or authorizations necessary to carry out
    the conditions of the order, and take whatever steps are necessary to ensure
    the protection of all environmental resources during construction and
    operation of the project and activities associated with abandonment. The
    authority shall allow:
    a.     the modification of conditions of the order;
    b.     stop work authority; and
    c.     the imposition of any additional measures deemed necessary to
    ensure continued compliance with the intent of the conditions of the order
    as well as the avoidance or mitigation of unforeseen adverse environmental
    impacts resulting from project construction and operation and
    abandonment.
    J.A. 624-25 (Appendix C to the Certificate).
    B.     Corps’ Section 404 Review and Virginia’s Related Section 401 Review
    MVP requested its Section 404 permit from the Corps by filing a “Joint Permit
    Application” in February 2016. See 
    33 U.S.C. § 1344
    (a). The application served as a
    preconstruction notification under “Nationwide Permit 12” (“NWP 12”), which concerns
    “activities required for the construction, maintenance, repair, and removal of utilities
    lines and associated facilities in waters of the United States.” J.A. 100. See 33 U.S.C.
    1344(e)(1) (allowing the Secretary of the Army to issue permits on a “nationwide basis
    for any category of activities involving discharges of dredged or fill material if the
    Secretary determines that the activities in such category are similar in nature, will cause
    only minimal adverse environmental effects when performed separately, and will have
    only minimal cumulative adverse effect on the environment”).          Applicants seeking
    coverage under that permit must provide information that the Corps can use “to
    determine that the adverse environmental effects of the activity will be no more than
    20
    minimal and to determine the need for compensatory mitigation or other mitigation
    measures.” J.A. 430. A project can be covered by NWP 12 only if it satisfies numerous
    conditions that apply generally to each nationwide permit. One such condition requires
    that construction include appropriate soil erosion and sediment controls. In this way,
    NWP 12 “ties in the requirements and practices of the VESC program and regulations.”
    J.A. 112. Additionally, although NWP 12 authorizes disturbance of streams temporarily
    during construction, the permit requires that streams be restored to pre-construction
    condition once construction is complete.
    In 2017, the Corps revised the requirements for NWP 12, see Issuance and
    Reissuance of Nationwide Permits, 
    82 Fed. Reg. 1860
    -01, 1985-86 (Jan. 6, 2017), which
    prompted MVP to revise its earlier-filed application. In MVP’s revised application, MVP
    discussed in detail the Project’s potential impacts on wetland, stream, and river crossings
    and the steps MVP would take to address them. In March 2017, the Corps added several
    Regional conditions specific to Virginia for the NWP 12.
    As per Virginia law, the State Agencies then considered whether NWP 12 and the
    certification conditions satisfied the criteria necessary for Section 401 certification. 9 Va.
    Admin. Code 25-210-130(H). Following its consideration of public comment, the Board
    issued its certification on April 7, 2017, concluding that the requisite criteria had been
    satisfied (the “April 401 Certificate”). The certification stated that “the Board finds that
    there is a reasonable assurance that the activities permitted under the Corps’ NWP
    program . . . will be conducted in a manner which will not violate applicable water
    21
    quality standards, provided permittees comply with all applicable Section 401
    conditions.” J.A. 452.
    C.     Virginia’s Approval of MVP’s Annual Standards and Specifications
    MVP first submitted its standards and specifications to DEQ in February 2016.
    Over the course of more than a year, DEQ engaged in several written and in-person
    exchanges with MVP representatives before finally approving the standards and
    specifications for the Project in June 2017 (“MVP’s Standards and Specifications”).
    They identify the measures MVP will take to meet the substantive requirements of the
    VESC and VSM Laws. They also outline how MVP will meet FERC’s requirements
    regarding its Upland Erosion Control, Revegetation, and Maintenance Plan and Wetland
    and Waterbody Construction and Mitigation Procedures.
    The approved standards and specifications include, among other things, plans to
    protect against impacts from landslides and blasting, requirements for addressing acidic
    silt, and assessing karst hazards. They also require MVP to monitor land-disturbing
    activities, conduct regular inspections, and report the results to DEQ. The technical
    requirements in MVP’s Standards and Specifications in fact exceed in several respects
    the requirements that the Virginia Construction General Permit imposes generally on
    large-scale construction projects. 8
    8
    For example, the standards and specifications require MVP to (1) install
    permanent waterbars and slope breakers in some locations 25 feet from waterbody
    boundaries, (2) install temporary berms and trench breakers to slow stormwater flowing
    along a right-of-way or trench, (3) reduce the width of the construction area for the 50
    feet on each side of a waterbody where possible, (4) restrict the undertaking of equipment
    (Continued)
    22
    In addition to these requirements, DEQ also informed MVP that it needed to
    submit site-specific plans to DEQ for its approval before commencing land-disturbing
    activities. These plans would “address every foot of land disturbance related to pipeline
    construction, including the path of the proposed pipeline right of way . . . , access roads,
    construction lay-down areas and construction activities that will occur in streams and
    wetlands.” J.A. 108. Additionally, DEQ required MVP to post these plans on its website
    so that the public could comment on them.
    D.     Virginia’s Section 401 “Supplemental Proceedings”
    On May 19, 2017, the same day DEQ issued the 2017 Guidance Document, it also
    issued an information request to MVP pursuant to the new policy. The request stated that
    it was “for the purpose of evaluating whether additional 401 certification conditions are
    necessary to ensure protection of water quality.” J.A. 7. Included in the many categories
    of information requested were “[a] complete listing of all type of project-related upland
    ground-disturbing activities that would occur within 50 feet of” surface waters; a list of
    sensitive waterbodies located within 50 feet of the land-disturbing activities; and
    information concerning various measures MVP would be taking to protect water quality,
    including a water-quality monitoring plan. J.A. 8. DEQ’s request marked the beginning
    of a supplemental process that involved many detailed exchanges of information between
    maintenance, storage, and refueling activities within 100 feet of any waterbody, and (5)
    disc and de-compact topsoil in disturbed areas during restoration of rights-of-way.
    23
    DEQ and MVP, as well as in-person work sessions involving representatives of various
    other state agencies.
    On July 3, 2017, DEQ issued a draft 401 certification that included 14 conditions
    that had not been included in the April 401 Certification (for the Corps’ 404 permit). The
    draft was shared with the public subject to DEQ’s notice and comment procedures,
    generating more than 8,000 comments. DEQ also held two public hearings regarding the
    certification. As this process continued, DEQ and MVP continued to discuss more water-
    quality related concerns, what measures would be employed to address the concerns, and
    how effective those measures would be. DEQ also entered into a contract with the
    United States Geological Service to monitor water quality during construction.
    As a result of this continued review, DEQ substantially revised its draft 401
    certificate, adding several new requirements. The revised draft included 15 conditions
    that were in addition to the many other requirements imposed by the various other
    governmental entities and laws. Those conditions included “specific requirements for
    best work practices emphasizing hazard assessment, frequent inspection requirements,
    monitoring    activities,   preventative   measures,   riparian   buffer   protections,   and
    comprehensive mitigation plans.” J.A. 130.
    In addition to preparing the revised draft certification, DEQ prepared other
    documents explaining its analysis, including a “Basis for Certification” and detailed
    responses to the public’s comments. DEQ also further explained its analysis when it
    presented its recommendation to the Board during a two-day public meeting in December
    2017.
    24
    As noted, the certification process required Virginia to determine that it had
    “reasonable assurance” that the Project would “not violate applicable water quality
    standards.”   
    40 C.F.R. § 121.2
    (a)(3).    DEQ recognized that “[t]he term ‘reasonable
    assurance’ is not defined in the [CWA] or applicable federal regulations.” J.A. 124. It
    reasoned that the standard “addresses future events” and thus is “inherently predictive in
    nature and absolute certainty is not required.” J.A. 103 n.4, 125. Still, DEQ reasoned
    that the term requires “more than a probability or mere speculation. J.A. 103 n.4, 125.
    DEQ concluded that, with all of the additional conditions imposed in the proposed
    Section 401 certification, that standard was met.
    DEQ noted that application of the VESC and VSM Laws through the annual
    standards and specification program would serve “to protect surface water quality during
    and after construction completion.”       J.A. 107.    DEQ also emphasized that the
    supplemental 401 review was only one of many programs and processes protecting
    Virginia’s water quality, each of which DEQ participated in.        These programs and
    processes included FERC’s environmental review; the CWA section 404 certification and
    related VWP permitting programs; DEQ’s review of stormwater and erosion control
    measures through the VESC and VSM Laws; DEQ’s supplemental Section 401 review of
    impacts of upland activities; and DEQ’s participation in the development of project-
    specific water-quality monitoring requirements. DEQ concluded that these programs,
    “[w]hen considered as a unified approach, . . . provide a thorough technical evaluation
    25
    and process that is designed to ensure that Virginia’s water quality is protected.” J.A.
    113. 9
    DEQ noted that in the process that culminated with issuance of the April 401
    Certification, DEQ had “already established reasonable assurance that activities in
    streams and wetlands” would “be conducted in a manner that [would] not violate
    applicable water quality standards.” J.A. 126. Reviewing the potential impact of the
    stream-crossing activities that were covered by NWP 12, DEQ emphasized that the
    permit requires the use of appropriate erosion and sediment controls.         DEQ also
    emphasized that NWP 12 requires, with regard to any stream crossing, that any
    disturbance will only be temporary and that the impact area must be restored to pre-
    construction condition once construction is complete. DEQ also noted that “[t]he VWP
    program and prior certification of the Corps’ Nationwide Permits has proven to be
    sufficient to evaluate and, when necessary, mitigate potential water quality impacts for
    linear construction projects, such as roads and pipelines.” J.A. 100.
    DEQ acknowledged that its review of the project-specific stormwater management
    and erosion and sediment control plans – the description of exactly how the annual
    standards and specifications would be applied foot-by-foot within the Project – would not
    be completed until after completion of Virginia’s Section 401 process. Nevertheless,
    DEQ’s reasonable-assurance determination of the upland activities depended in part on
    9
    The document explained that the earlier-issued 401 certification for the
    Corps’ Nationwide Permit and the additional proposed 401 certification “together would
    constitute the Commonwealth of Virginia’s 401 Certification for the MVP Project.” J.A.
    103 (emphasis in original).
    26
    the facts (1) that no land-disturbing activity could begin until those plans had been
    approved, and (2) that the plans would not be approved unless they satisfied MVP’s
    Standards and Specifications, which DEQ had already determined complied with the
    applicable statutory and regulatory requirements. DEQ also noted that Virginia’s AS&S
    Program “incorporates the same engineering, erosion and sediment control,
    recordkeeping, monitoring, inspecting and post construction stormwater management
    requirements that are otherwise implemented in the . . . Construction General Permit (
    9 Va. Admin. Code § 25-880-1
     et seq.).” J.A. 126. DEQ drew assurance from the fact that
    a Richmond Circuit Court had recently upheld the Construction General Permit on the
    basis that “substantial evidence in the record [supported] the Board’s determination that
    proper implementation of permit conditions, including inspections and corrective action,
    would protect water quality.” J.A. 127; see Order, Kelble v. Commonwealth, Case No.
    CL14-762, at 4-5 (Richmond Cir. Ct. Apr. 10, 2017) (concluding in appeal challenging
    whether Construction General Permit adequately protected water quality that substantial
    evidence supported Board’s determination that proper implementation of the conditions
    of the permit, including inspections and adaptive actions, would protect water quality).
    And DEQ placed strong reliance on the EPA’s conclusion that its own construction
    general permit was sufficient to prevent projects from negatively affecting water quality.
    DEQ emphasized that it “traditionally rel[ies] on the technical studies and analysis of
    [the] EPA” because DEQ lacks the money or manpower to do the “in-depth analyses”
    that the EPA does. J.A. 305.
    DEQ concluded,
    27
    In the absence of information demonstrating otherwise, compliance with
    the requirements under the [AS&S] Program will result in stormwater
    discharges being controlled as necessary to meet applicable water quality
    standards and antidegradation requirements.          More specifically, by
    imposing requirements that discharges to impaired, TMDL [Total
    Maximum Daily Load], and exceptional waters comply with additional
    requirements, to stabilize exposed areas faster and to conduct site
    inspections more frequently than other sites (in addition to meeting
    [stormwater and erosion] requirements), authorizing these discharges will
    not result in a lowering of water quality. Thus, DEQ has determined that
    compliance with the [AS&S] approval generally is sufficient to satisfy Tier
    2 and Tier 3 antidegradation requirements because the controls will not
    result in a lowering of water quality, making individualized Tier 2 or Tier 3
    review unnecessary.
    J.A. 128-29. The DEQ added that its determination that the AS&S Program would
    ensure compliance with water quality standards and antidegradation requirements was
    supported by the fact that the requirements under that program met the technical
    requirements of the Construction General Permit and that the EPA had stated in its 2017
    Construction General Permit fact sheet that compliance with that permit was generally
    sufficient to prevent any lowering of water quality. See J.A. 1075 (“EPA has determined
    that compliance with the [Construction General Permit] generally will be sufficient to
    satisfy Tier 2 (or 2.5) and Tier 3 antidegradation requirements because the controls will
    not result in a lowering of water quality, making individualized Tier 2 or Tier 3 review
    unnecessary.”).
    DEQ also noted that FERC had concluded – prior to Virginia’s adding any
    conditions in the Section 401 process – that impacts on water resources were “expected to
    return to baseline levels over a period of days or weeks following construction given the
    requirement to restore water bodies to their original contours.” J.A. 132. Given that fact,
    28
    and the fact that the Corps’ approval would be necessary regarding any stream or
    wetlands crossings, “FERC [had] concluded that the cumulative effect on surface
    waterbody resources would be minor.” J.A. 132. Similarly, DEQ took notice of the fact
    that the Corps would be assessing in detail “geographic areas that are determined to be
    potentially subject to more than minimal cumulative adverse environmental effects,” and
    the Corps will have authority to add conditions to NWP 12 “to require mitigation
    measures to ensure that the cumulative adverse environmental effects of these activities
    are no more than minimal.” J.A. 133-34.
    Finally, DEQ emphasized that the proposed 401 certification required MVP to
    develop a limited water-quality monitoring plan to monitor and evaluate potential
    impacts from activities not subject to the Corps’ Section 404 permit. DEQ noted that the
    plan MVP submitted included in-stream monitoring of water quality in proximate upland
    areas. The monitoring would occur before, during, and after construction, and would
    evaluate temperature, turbidity, dissolved oxygen, and pH. Elevated sample results “that
    exceed the applicable water quality criteria” would require consultation between MVP
    and DEQ so that they could respond appropriately.           J.A. 92.   In addition to this
    monitoring, DEQ noted it would be conducting “project-specific water quality
    monitoring at a number of proposed . . . stream crossings near sensitive and/or critical
    areas” that also “will be conducted before, during and after . . . construction activities.”
    J.A. 139. DEQ noted that the monitoring had already begun in the fall of 2017 in order
    “[t]o establish a baseline of water quality conditions,” and that it would continue if the
    project were approved until “at least one year after completion of construction.” J.A.
    29
    140. DEQ stated that “[t]he monitoring is intended to provide reasonable assurance that
    erosion and sediment control measures are effective” and that “[i]f necessary, changes
    will be made to approved erosion and sediment control plans based on conditions
    encountered in the field during construction.” J.A. 140.
    During the two-day meeting held by the Board to consider DEQ’s
    recommendation, the Board further amended the draft certificate, including adding one
    additional condition. The Board approved the certificate as amended, and on December
    8, 2017, DEQ issued a final certification (the “December 401 Certification”).         The
    certification stated that it “addresses Project activities in upland areas outside of the
    Corps jurisdictional areas under 
    33 U.S.C. § 1344
     and water withdrawal activities that are
    exempt from coverage under the Virginia Water Protection Permit Program Regulation (9
    [Va. Admin. Code] § 25-210-10, et seq.).” 10 J.A. 48. The certification declared that
    “[t]he additional conditions contained in . . . this Certification along with the
    requirements imposed by the VWP regulation, the Corps Section 404 permitting
    requirements, and prior regulatory actions associated with the approval and requirements
    10
    The certificate continued:
    In the manner and to the extent described herein, this includes all proposed
    upland activities associated with the construction, operation, maintenance,
    and repair of the pipeline, any components thereof or appurtenances
    thereto, and related access roads and rights-of-way as well as certain
    project-related surface water withdrawals. This Certification covers all
    relevant upland Project activities within the route identified in the
    Environmental Impact Statement.
    J.A. 48.
    30
    of the June 2017 Annual Standards and Specifications, and the April 7, 2017 Section 401
    Water Quality Certification of the Corps Nationwide Permit 12 provide reasonable
    assurance that water quality standards will not be violated.” J.A. 53.
    E.     Petitions For Review and Subsequent Events
    On December 8, 2017, and December 18, 2017, separate petitions for review were
    filed by various entities challenging the December 401 Certification. Both petitions
    named the Board, the Board’s members, DEQ, DEQ’s Director, and DEQ’s Director of
    its Water Permitting Division as respondents (“Respondents”).            We subsequently
    consolidated the petitions and granted MVP’s motion to intervene.
    On December 26, 2017, the Corps’ Norfolk District verified that MVP could rely
    on NWP 12 for its stream crossings. FERC began issuing notices to proceed with
    construction on January 22, 2018.
    III.
    As noted earlier, section 717r of the NGA provides appellate jurisdiction over a
    state administrative agency’s grant of a Section 401 certificate, in “[t]he United States
    Court of Appeals for the circuit in which a facility subject to [15 U.S.C. §717f] is
    proposed to be constructed, expanded, or operated.” 15 U.S.C. § 717r(d)(1). And it is
    undisputed here that the Project is subject to 15 U.S.C. § 717f.            Nevertheless,
    Respondents and MVP both argue that Petitioners lack standing to litigate this petition
    for review. We disagree.
    Article III   gives federal courts jurisdiction only over           “[c]ases” and
    “[c]ontroversies.”   U.S. Const. art. III, § 2, cl. 1.     “One essential aspect of this
    31
    requirement is that any person invoking the power of a federal court must demonstrate
    standing to do so.” Hollingsworth v. Perry, 
    570 U.S. 693
    , 704 (2013). To establish
    Article III standing, Petitioners must allege that (1) they suffered an actual or threatened
    injury that is concrete, particularized, and not conjectural; (2) the injury is fairly traceable
    to the challenged conduct; and (3) the injury is likely to be redressed by a favorable court
    decision. See Spokeo, Inc. v. Robins, 
    136 S. Ct. 1540
    , 1547-48 (2016).
    Petitioners are individuals and other entities who allege the construction of the
    pipeline would cause them (or their members) injuries related to their various interests in
    the affected waters. Although Respondents and MVP do not dispute that Petitioners
    sufficiently allege that they will be harmed by construction of the Project, they
    nevertheless contend that Petitioners cannot establish any of the three standing prongs.
    Respondents and MVP contend it was FERC’s granting of its permit that caused any
    injuries that Petitioners are suffering insofar as it was FERC’s permit that allowed the
    Project to proceed. MVP also argues that even were Petitioners to prevail on the merits
    and we were to vacate the December 401 Certificate and remand for further proceedings,
    Petitioners would need to clear several additional hurdles to eventually obtain the
    ultimate relief that they seek, namely, more stringent certificate conditions or complete
    discontinuation of the Project.
    The standing principles that control here are those we applied in Townes v. Jarvis,
    
    577 F.3d 543
    , 547 (4th Cir. 2009). In that case, the Virginia Parole Board found prisoner
    Townes ineligible for discretionary parole pursuant to a three-strikes statute. See 
    id. at 545-46
    . After he was denied state habeas relief, he filed a federal habeas petition,
    32
    claiming that the parole-ineligibility determination violated his due process and equal
    protection rights. See 
    id. at 546
    . The district court dismissed the petition. See 
    id.
     We
    granted a certificate of appealability on both claims. See 
    id.
     A threshold question in the
    appeal was whether Townes’s case was mooted by his release from prison on mandatory
    parole while his appeal was pending. We concluded that the case was not moot because
    each standing element remained satisfied. See 
    id. at 546-49
    .
    We concluded that Townes properly asserted injury-in-fact insofar as the parole-
    ineligibility decision cost him the opportunity to receive a shorter period of parole. See
    
    id. at 547
    . We reasoned that were he found to be eligible for parole, he would receive a
    discretionary parole hearing, which would be the opportunity for a shorter parole period.
    See 
    id.
     Because it was the parole board’s parole-ineligibility decision that deprived
    Townes of a discretionary hearing, we concluded his injury was fairly traceable to the
    parole-ineligibility decision. See 
    id.
     Furthermore, Towne’s lost-opportunity injury was
    redressable insofar as a favorable decision on the merits could result in him receiving a
    discretionary parole hearing. See 
    id.
    We noted that to establish redressability, Townes did not need to show that his
    obtaining a discretionary parole hearing would likely result in a shortened parole period.
    See 
    id.
     We explained,
    In some cases, like the one at hand, a plaintiff will seek immediate relief
    from a federal court as a necessary antecedent to the ultimate relief he seeks
    from a different entity, like an administrative agency. In these situations, to
    meet the redressability prong, a party must demonstrate that a favorable
    decision from the federal court likely would provide him immediate relief,
    but need not demonstrate that it likely would provide him the ultimate,
    discretionary relief sought from the agency.
    33
    
    Id.
     (emphasis in original) (citing FEC v. Akins, 
    524 U.S. 11
    , 25 (1998)). We explained
    that “to require a showing of likelihood of ultimate relief in this situation would involve
    courts in the speculative (if not impossible) task of predicting how an agency will
    exercise its discretion.” Id. at 548. Still, we noted that the prospect of the plaintiff’s
    achieving the ultimate relief he seeks is not altogether irrelevant to the issue of
    redressability: “[I]f no realistic possibility exists that a plaintiff can obtain the ultimate
    relief,” then he cannot show redressability. Id. (internal quotation marks omitted).
    The facts of the present case are closely analogous to those of Townes. As in
    Townes, Petitioners challenge what they claim is an improper administrative decision that
    they had hoped and expected would yield a more favorable result. Also as in Townes,
    they seek “immediate relief from a federal court as a necessary antecedent to the ultimate
    relief [they] seek[] from a different entity, like an administrative agency.” Id. at 547
    (emphasis in original). We therefore analyze the standing issue here applying the same
    principles we used in Townes.
    Applying these principles, we conclude Petitioners have standing. Just as the
    board’s parole-ineligibility decision ended Townes’s opportunity to receive a
    discretionary parole hearing (and the shorter parole period he would have hoped to
    receive from that hearing), the December 401 Certification ended Petitioners’ opportunity
    to have more stringent requirements imposed (or the Project vetoed entirely). Thus, like
    Townes, Petitioners have properly asserted injury-in-fact fairly traceable to the decision
    they challenge. And also like Townes, were Petitioners to prevail on the merits of their
    claims in federal court, the court could immediately undo the administrative decision that
    34
    caused their injury. As was true in Townes, analyzing redressability does not require us
    to predict whether, if we rule for Petitioners on the merits, they will eventually obtain the
    ultimate relief that they seek. 11     Rather, to show redressability, they need only
    demonstrate a “realistic possibility” that they will obtain that ultimate relief. Id. at 548
    (internal quotation marks omitted).
    As MVP points out, in order to obtain the relief Petitioners ultimately seek –
    tighter restrictions or a complete discontinuation of the Project – Petitioners would need
    to clear several hurdles even after prevailing on the merits before us. At the very least,
    they would need the State Agencies to decide on remand not to elect to waive any further
    review. See 
    33 U.S.C. § 1341
    (a). Then they would need the State Agencies to decide to
    deny reissuance of the 401 certification or at least to impose stricter conditions. And as
    MVP points out, even if the State Agencies decided to take that course, FERC
    theoretically could resist their efforts by arguing, for example, that it is too late in the
    11
    Citing Doe v. Virginia Department of State Police, 
    713 F.3d 745
    , 755 (4th
    Cir. 2013), MVP suggests that to show redressability, Petitioners must show it is likely
    they would obtain their ultimate relief should we rule for them on the merits of their
    petition. But Doe does not apply here. In Doe we explicitly concluded that the
    redressability rule of Townes did not apply because the plaintiff did not meet the criteria
    for applying the rule, namely she was not “seek[ing] immediate relief from a federal
    court as a necessary antecedent to the ultimate relief [s]he seeks from a different entity,
    like an administrative agency.” 713 F.3d at 756 n.7 (internal quotation marks omitted).
    Because Petitioners here are seeking such relief, they are entitled to the benefit of the
    Townes rule and thus do not need to show they will likely eventually obtain the ultimate
    relief in order to show redressability.
    35
    process for the State Agencies to make such a decision or that further restrictions would
    be preempted.
    In our view, however, none of these potentialities are sufficient to negate the
    “realistic possibility” that if Petitioners prevailed on the merits of this petition, they
    would obtain at least more stringent requirements on remand. Petitioners argue that
    FERC would be legally required to add any conditions requested by the State Agencies
    on remand or to honor a decision by the State Agencies to deny 401 re-certification. But
    even assuming Petitioners are incorrect, and FERC had some discretion on the subject,
    there is good reason to believe FERC would be amenable to the State Agencies’ attempts
    to re-issue its 401 certification with more stringent restrictions.    FERC’s certificate
    plainly gave the OEP Director discretion to stop construction or to impose additional
    conditions for protection of the environment. 12 And, FERC has general authority to issue
    supplemental orders in any event. See 
    18 C.F.R. § 153.11
     (FERC “may make, at any
    time subsequent to the original order of authorization, after opportunity for hearing, such
    supplemental orders implementing its authority under section 3 of the Natural Gas Act as
    it may find necessary or appropriate.”).
    If the State Agencies determined on remand that additional conditions would be
    needed to give them reasonable assurance that their water quality would be protected,
    they would have strong arguments to make that FERC could not, or at least should not,
    12
    Moreover, Virginia’s certificate expressly recognized that it could be
    revoked, even though judicial vacatur was not specifically referenced as a basis for
    revocation.
    36
    stand in their way. It is undisputed, after all, that so long as the state does not waive the
    right to participate, a state’s grant of a Section 401 certificate is a precondition for
    FERC’s ability to issue its certificate.      See 
    33 U.S.C. § 1341
    (a)(1) (providing that
    applicant for a FERC permit “shall provide” FERC with a Section 401 Certificate, and
    “[n]o license or permit shall be granted until the certification required by this section has
    been obtained or has been waived”); see also 
    33 U.S.C. § 1341
    (d) (“Any [Section 401]
    certification . . . shall become a condition on any Federal license or permit subject to the
    provisions of this section.” (emphasis added)); American Rivers, Inc. v. FERC, 
    129 F.3d 99
    , 107 (2d Cir. 1997) (explaining that Section 401’s language “leav[es] little room for
    FERC to argue that it has authority to reject state conditions it finds to be ultra vires”).
    MVP is no doubt correct that, were FERC inclined to resist the State Agencies’
    efforts, it would have colorable arguments it could assert as well. And for that reason, we
    cannot say with certainty how FERC would react. Fortunately, however, it is not our role
    to engage “in the speculative (if not impossible) task of predicting how an agency will
    exercise its discretion.” Townes, 
    577 F.3d at 548
    . Rather, it is sufficient for us to
    conclude, as we do here, that there is at least a realistic possibility that the State Agencies
    would successfully impose more restrictive conditions (or deny re-certification) were we
    to vacate the December 401 Certification. We therefore determine that the possibility
    Petitioners could prevail on the petition before us and yet still not obtain the relief they
    ultimately seek does not preclude them from showing redressability. Rather, we hold that
    Petitioners have demonstrated standing to assert the claims contained in their petition for
    review, and it is to those claims that we now turn.

    IV.
    A.
    We review Virginia’s Section 401 certification under the arbitrary-and-
    capriciousness standard. 13 See AES Sparrows Point LNG, LLC, 
    589 F.3d at 733
    . “[T]he
    scope of our review under [that] standard is narrow and highly deferential.”            
    Id.
    “Especially in matters involving not just simple findings of fact but complex predictions
    based on special expertise, ‘a reviewing court must generally be at its most deferential.’”
    Ohio Valley Envtl. Coal., 
    556 F.3d at 192
     (quoting Baltimore Gas & Elec. Co. v. NRDC,
    
    462 U.S. 87
    , 103 (1983)).
    In determining whether agency action was arbitrary or capricious,
    the court must consider whether the agency considered the relevant factors
    and whether a clear error of judgment was made. Although this inquiry
    into the facts is to be searching and careful, the ultimate standard of review
    is a narrow one. The court is not empowered to substitute its judgment for
    that of the agency. Deference is due where the agency has examined the
    relevant data and provided an explanation of its decision that includes a
    rational connection between the facts found and the choice made.
    
    Id. at 192
     (internal quotation marks and citations omitted).
    B.
    13
    Petitioners argue for application of this standard. And Respondents
    acknowledge that “courts reviewing challenges under Section 401 – including this Court
    – have often looked to the APA [Administrative Procedure Act, see 
    5 U.S.C. § 706
    (2)(A)]” and applied the arbitrary-and-capricious standard of review. Respondents’
    brief at 27. Nevertheless, they question whether this approach is correct given that the
    APA “does not cover state agencies.” Delaware Riverkeeper Network v. Secretary of Pa.
    Dep’t of Envtl. Prot., 
    870 F.3d 171
    , 179 n.8 (3d Cir. 2017); see 
    5 U.S.C. § 701
    (b)(1).
    They suggest that Virginia law should supply the standard, which they maintain would
    require application of the substantial-evidence standard of review. We need not resolve
    this issue, however, because Petitioners’ claims fail even under their preferred standard.
    38
    Petitioners argue, for two reasons, that the State Agencies acted arbitrarily and
    capriciously in issuing the December 401 Certificate.
    1.
    First, they contend that DEQ did not have a sufficient basis to find reasonable
    assurance that the types of measures, restrictions, and programs in place to prevent excess
    sediment from entering state waters would be effective to satisfy the requirements of
    Virginia’s antidegradation policy. We disagree.
    The construction of the Project was exactly that, a large construction project, and
    the State Agencies very reasonably undertook to protect their waters with the “tried and
    true” methods developed for just this purpose.           Indeed, MVP’s Standards and
    Specifications incorporate the very same substantive protections as are contained in the
    Virginia Construction General Permit. The State Agencies justifiably drew confidence in
    these protections from the EPA’s judgment regarding the effectiveness of these same
    protections in preventing construction from negatively impacting water quality. And a
    Richmond Circuit Court concluded as well that the Virginia Construction General Permit
    was sufficient to prevent any negative impacts on water quality. See Order, Kelble v.
    Commonwealth, Case No. CL14-762, at 4-5 (Richmond Cir. Ct. Apr. 10, 2017).
    Petitioners nonetheless contend, for several reasons, that the State Agencies acted
    arbitrarily in relying on the EPA’s judgment regarding the general effectiveness of these
    protections. They argue, for example, that interstate gas pipelines “can have significantly
    greater impacts than the smaller projects authorized by EPA’s General Permit.”
    Petitioners’ Reply brief at 19. But Petitioners do not suggest any reason why it was
    39
    arbitrary for the State Agencies to assume that those same methods used for years to
    prevent large construction projects from harming water quality would not continue to be
    effective on an even larger scale.
    Petitioners also argue that the federal General Permit has an element that is not
    present with regard to the Project here because, “[u]nlike the NPDES program, the
    [VESC] Law under which the [AS&S] are approved does not mandate compliance with
    water quality standards.” Petitioners’ Reply brief at 19-20. However, while MVP’s
    Standards and Specifications do not directly incorporate Virginia’s water quality
    standards, the December 401 Certification incorporates MVP’s water-quality monitoring
    plan. That plan in turn requires MVP to promptly report any sampling results “that
    exceed the applicable water quality criteria,” so that DEQ and MVP can quickly engage
    in consultation and make appropriate adjustments. J.A. 92. As DEQ explained to the
    Board, it is of course true that Section 401 certifications are “inherently predictive in
    nature.” J.A. 103 n.4, 125. See Port of Seattle v. Pollution Control Hearings Bd., 
    90 P.3d 659
    , 679 (Wash. 2004) (“[A] finding of ‘reasonable assurance’ is predictive in
    nature.”). Cf. Ohio Valley Envtl. Coal. v. Bulen, 
    429 F.3d 493
    , 501 (4th Cir. 2005)
    (noting in context of section 404 that “it is impossible for the Corps’ ex ante
    determinations of minimal impact to be anything more than reasoned predictions”).
    Nonetheless, it was reasonable for the State Agencies to conclude that DEQ, like the
    EPA, would be able to use the tools at its disposal to adjust to any unexpected
    contingencies that may lead to a short-term exceedance. We note that § 1341(d) plainly
    contemplates a state requiring water monitoring as a basis for its reasonable assurance
    40
    certification. See 
    33 U.S.C. § 1341
    (d) (“Any certification provided under this section
    shall set forth any . . . monitoring requirements necessary to assure that any applicant for
    a Federal license or permit will comply with any applicable . . . limitations . . . and with
    any other appropriate requirement of State law set forth in such certification.”). We see
    no reason why reliance on such monitoring would be arbitrary or capricious. See Port of
    Seattle, 90 P.3d at 678. 14
    In their opening brief, Petitioners argue that even quick adjustments by DEQ to
    minor exceedances would necessarily be insufficient to “maintain[] and protect[]” Tier 2
    water quality, as Virginia’s antidegradation policy requires. 9 Va. Admin. Code 25-260-
    30(A)(2). Petitioners argue that allowing any additional discharge of sediment to Tier 2
    waters, no matter how small in quantity or temporary in duration the exceedance is,
    would violate DEQ’s duty to “maintain[] and protect[]” water quality in these waters. Id.
    As Respondents and MVP both noted in their response briefs, however, the State
    Agencies do not construe their antidegradation policy so rigidly. Rather, they take the
    14
    For similar reasons, we conclude it was not arbitrary for the State Agencies
    to issue the December 401 Certificate before the site-specific erosion and stormwater
    management plans were finalized. Just as the existence of the plan to monitor water
    quality during construction was an important part of its reasonable assurance even though
    construction had not yet begun, the requirement that DEQ approve the site-specific plans
    was important even though the plans had not been finalized. See Port of Seattle v.
    Pollution Control Hearings Bd., 
    90 P.3d 659
    , 677 (Wash. 2004) (holding regulators did
    not act arbitrarily or capriciously by basing reasonable assurance “on future submissions
    of revised plans, reports, and studies, so long as their implementation and anticipated
    outcome meet the reasonable assurance test”). Although the significance of both of these
    protections depended upon DEQ’s future responses to future events, we do not believe it
    was arbitrary for the State Agencies to trust that DEQ officials would respond
    appropriately.
    41
    view that they can still “maintain[] and protect[]” water quality despite momentary
    exceedances so long as they can quickly detect such exceedances and promptly respond
    with appropriate changes in to prevent any significant degradation. See Va. Dep’t of
    Envtl. Quality, Guidance Memo No. 00-2011, Guidance on Preparing VPDES Permit
    Limits (Aug. 24, 2000), at 9 (“Since the quality of tier 2 waters is better than required by
    standards, no significant degradation of the existing quality will be allowed.” (emphasis
    added)). We defer to the agencies’ reasonable construction of their own regulations. See
    Delaware Riverkeeper Network v. Secretary of Pa. Dep’t of Envtl. Prot., 
    870 F.3d 171
    ,
    181 (3d Cir. 2017); Clark v. Alexander, 
    85 F.3d 146
    , 152 (4th Cir. 1996).              And
    Petitioners do not challenge the reasonableness of DEQ’s construction here.             Cf.
    Petitioners’ Reply brief at 17-18 (acknowledging DEQ’s construction).
    Certainly, it must be anticipated with large construction projects, that unexpected
    problems will arise, leading at least to minor, short-term issues. Were Virginia’s policy
    interpreted as rigidly as Petitioners suggest, no project affecting Tier 2 waters could ever
    be approved without an economic/social development need analysis. See 
    9 Va. Admin. Code § 25-260-30
    (A)(2) (providing that the quality of Tier 2 waters “shall be maintained
    and protected unless the board finds . . . that allowing lower water quality is necessary to
    accommodate important economic or social development in the area in which the waters
    42
    are located”). Especially given this reality, we find nothing unreasonable in DEQ’s
    interpretation of the policy. 15
    Petitioners also maintain that the State Agencies acted arbitrarily by relying on
    EPA’s judgment regarding the general effectiveness of the type of protections in place for
    the Project rather than taking a more site-specific approach. Petitioners point to evidence
    in the record supporting their view that the protections in place here would not be
    effective in preventing construction impacts from lowering water quality given the
    specific characteristics of the Project, particularly the steep topography of the land at
    issue. 16 But we conclude that the State Agencies’ approach appropriately blended site-
    specific and non-site specific analyses. The December 401 Certification incorporates a
    Landslide Mitigation Plan. For example, as DEQ explained in its response to public
    comments to its draft certification,
    15
    Respondents also point out that Tier 3 waters receive the “highest level of
    protection,” 
    63 Fed. Reg. 36742
    -01, at 36786 (July 7, 1998), and even in those waters,
    “[a]ctivities causing temporary sources of pollution may be allowed . . . even if
    degradation may be expected to temporarily occur provided that after a minimal period of
    time the waters are returned or restored to conditions equal to or better than those existing
    just prior to the temporary source of pollution.”        
    9 Va. Admin. Code § 25-260
    -
    30(A)(3)(b)(3).
    16
    For example, they point to one particular study that concluded that
    sedimentation at one crossing affected by the Project would increase by 1,536 percent
    during construction even with best management practices and would permanently
    increase sedimentation by 15% even after reclamation and revegetation. They also cite
    several analyses from a hydrologist who concludes that MVP’s best management
    practices would not in fact be sufficient to prevent significant adverse impacts to the
    state’s water quality. And they point to evidence that other pipelines built in less
    challenging terrain that have caused substantial water quality impacts.
    43
    Plan development included field observations for these sites including:
    slope characteristics, GPS mapping of observed slides, slumps, rockfalls,
    scarp locations, the presence of geotropically affected trees, drainage
    features, and gullying. The Plan includes mitigation strategies such as
    excavation and/or regarding of upgradient head soils, dewatering, rock
    embedment as well as construction operations including buttressing and
    reinforced soil slope.
    Landslide mitigation also will depend on the installation of appropriate
    drainage and erosion control measures during construction and proper
    right-of-way reclamation. Certain site-specific measures have already been
    identified for certain high risk areas and others will be applied as field
    conditions indicate the need.
    J.A. 138.
    Moreover, DEQ has emphasized that it “traditionally rel[ies] on the technical
    studies and analysis of the EPA” because DEQ lacks the money or manpower to do the
    “in-depth analyses” that the EPA does. J.A. 305. While it is always true that government
    agencies could undertake analysis that is more in-depth and more specific to a particular
    project, we do not believe the State Agencies acted arbitrarily in placing significant
    reliance on the effectiveness of its “tried and true” methods here.      In making this
    judgment, we cannot ignore the fact that the State Agencies vigorously participated at
    every stage of the decision-making process and did not issue their final 401 certificate
    until they had added all of the protections that they concluded were needed to give them
    reasonable assurance that state water quality would be protected. This is exactly how the
    system was designed to work.
    At its essence, Petitioners’ position is that, having chosen to participate in the
    process, Virginia was foreclosed from placing significant reliance on the judgment of
    federal agencies regarding the general effectiveness of the types of protections in place
    44
    here and was limited in the types of evidence on which it could base its reasonable-
    assurance certification. We see no reason why Virginia should be so hamstrung. And we
    see no purpose we would serve by stepping in and second-guessing the analytical
    methods Virginia deemed appropriate to provide it with reasonable assurance that its
    water quality would be protected.
    2.
    Petitioners (and amicus Chesapeake Bay Foundation) also challenge the State
    Agencies’ decision to analyze the impacts from activities covered by NWP 12 separately
    from the impacts from upland activities related to construction.        In light of this
    segmentation, Petitioners maintain that issuance of the December 401 Certification was
    arbitrary and capricious because the State Agencies “fail[ed] to consider the combined
    effect of the upland activities and the stream and wetland crossings.”       Petitioners’
    Opening brief at 35. We disagree.
    We note initially that the petition for review here challenges only the December
    401 Certification.   There is thus no argument before us that the State Agencies
    improperly limited the scope of their April 401 Certification to the impact of activities
    covered by NWP 12. What we do consider today is Petitioners’ argument that the State
    Agencies erred by not including the impact of activities covered by NWP 12 within the
    scope of their supplemental 401 process.
    We find this criticism to be unfounded. Contrary to Petitioners’ suggestion, DEQ
    “did not review the Project’s potential upland impacts in a vacuum.” MVP’s brief at 51.
    Rather, DEQ “fully integrated [its earlier] analysis into its review of upland impacts.”
    45
    MVP’s brief at 50. Indeed, DEQ explained in its “Basis for Certification” that it was its
    intention that the April 401 Certification for the activities covered by NWP 12 and the
    additional proposed 401 certification “together would constitute the Commonwealth of
    Virginia’s 401 Certification for the MVP Project.” 17 J.A. 103 (emphasis in original).
    DEQ’s analysis in the supplemental process included consideration of the impacts the
    activities covered by NWP 12 were expected to have. Thus, although the December 401
    Certification “addresse[d] only activities in upland areas,” J.A. 48, and determined that
    there was reasonable assurance that allowing these activities would not reduce water
    quality, DEQ made this determination with full awareness and consideration of the fact
    that the NWP 12-covered activities would also be occurring. And in the end, DEQ made
    clear that it was only “[t]he additional conditions contained in Section V of the draft
    certification along with the requirements imposed by the VWP regulation, the Corps
    Section 404 permitting requirements, and prior regulatory actions associated with the
    approval and requirements of the June 2017 [Annual Standards and Specifications],” that
    “provide[d] reasonable assurance that water quality standards will not be violated.” J.A.
    113 (emphasis added). Finally, as we have discussed, a significant basis for the State
    Agencies’ reasonable-assurance certification was the existence of monitoring
    17
    The April 2017 Certification concerned only “activities permitted under the
    Corps’ NWP program.” J.A. 452. As the Board was considering whether to approve the
    issuance of a Section 401 certification for upland activities, several Board members made
    clear that they wanted to ensure that the language of that certificate would not foreclose
    the Board from participating in any future Section 401 process if the Corps decided to
    issue individual permits as opposed to relying entirely on coverage under NWP 12.

    requirements that would allow DEQ to make prompt adjustments if samples revealed
    exceedances of pre-construction sedimentation levels. In this way, the monitoring plan
    protected against any degradation of water quality from the Project, without regard to
    what particular activities (or combination of activities) was the cause.   For all of these
    reasons, we conclude that the State Agencies’ segmented approach to the December 401
    Certification, even if unorthodox, was not arbitrary and capricious.
    V.
    In sum, because we conclude that the State Agencies did not act arbitrarily and
    capriciously in issuing the December 401 Certification, we deny the petition for review.
