    * Hon. David H. Souter, Associate Justice (Ret.) of the
    Supreme Court of the United States, sitting by designation.
    KAYATTA, Circuit Judge.          Algonquin Gas Transmission, LLC
    ("Algonquin") seeks to build a natural gas compressor station in
    Weymouth, Massachusetts as one component of Algonquin's larger
    effort to improve its natural-gas delivery infrastructure in the
    northeastern United States.         Algonquin has received a certificate
    of public convenience and necessity ("CPCN") from the Federal
    Energy Regulatory Commission ("FERC"), but that certificate is
    conditioned upon the receipt of a consistency determination from
    the Commonwealth of Massachusetts pursuant to the Coastal Zone
    Management        Act   ("CZMA").        To    complete   its     CZMA   review,
    Massachusetts requires Algonquin to furnish a permit from the
    Massachusetts Department of Environmental Protection ("MassDEP").
    But MassDEP will not issue such a permit until the Town of Weymouth
    approves the project under its local ordinance or a court finds
    that ordinance preempted as applied to the project.
    After      unsuccessfully    seeking    Weymouth's    approval   to
    begin construction, Algonquin repaired to the U.S. District Court
    for the District of Massachusetts, from which it obtained a ruling
    that Weymouth’s ordinance, as applied to the project, is indeed
    preempted.        Weymouth now appeals that ruling.          For the following
    reasons, we affirm.
    I.
    We    briefly    survey     the    regulatory    topography,     the
    pertinent facts, and the procedural history in this case.
    - 2 -
    A.
    The       federal       Natural      Gas       Act    ("NGA")     governs     the
    transportation and sale of natural gas in interstate commerce and
    the importation and exportation of natural gas in foreign commerce.
    See 
    15 U.S.C. § 717
    (b).             The NGA requires a prospective developer
    to obtain a CPCN from FERC prior to constructing a jurisdictional
    natural gas pipeline or ancillary facility.                         
    Id.
     § 717f(e).       FERC
    must issue a CPCN if the applicant demonstrates that it "is able
    and willing . . . to conform to the provisions of [the Act] . . .
    and    regulations         of    [FERC]"   and       the    proposed    construction       is
    "required       by    the       present    or    future       public    convenience       and
    necessity."          Id.    In issuing a CPCN, FERC also has the authority
    to     impose    "reasonable         terms      and    conditions        as     the   public
    convenience and necessity may require."                       Id.
    The other federal statute relevant to this appeal, the
    CZMA, provides grants of money to states that adopt federally
    approved coastal-management programs.                        See generally 
    16 U.S.C. § 1455
    .     Among other requirements, a coastal-management program
    must    define       the    "permissible        land       uses   and   water    uses"   and
    promulgate "[b]road guidelines on priorities of uses" within the
    state's coastal zones.             
    Id.
     § 1455(d)(2).              The CZMA limits FERC's
    certificate-granting authority in at least one important way:                             It
    prohibits FERC from granting a permit to conduct an activity that
    will affect "any land or water use or natural resource of the
    - 3 -
    coastal      zone"    until     the    state     concurs      with   an    applicant's
    determination        that     the    proposed     activity     "complies     with     the
    enforceable policies of the state's approved [coastal-management
    program]."         Id. § 1456(c)(3)(A).             The Massachusetts Office of
    Coastal Zone Management ("Massachusetts OCZM") administers the
    Commonwealth's CZMA program.
    Two    local     laws    also     bear    on    this   dispute.         The
    Massachusetts        Wetlands        Protection       Act    ("Massachusetts     WPA")
    provides performance standards for construction activities in
    wetlands areas.        See 
    Mass. Gen. Laws ch. 131, § 40.1
                    The Act "sets
    forth minimum standards only, 'leaving local communities free to
    adopt more stringent controls.'"                Lovequist v. Conservation Comm'n
    of Dennis, 
    393 N.E.2d 858
    , 863 (Mass. 1979) (quoting Golden v.
    Selectmen of Falmouth, 
    265 N.E.2d 573
    , 577 (Mass. 1970)).                       It also
    requires a developer to file a notice of intention with and obtain
    an   order    of     conditions       from    the    municipality     in    which     the
    construction is to be located prior to commencing construction.
    
    Mass. Gen. Laws ch. 131, § 40
    .                  Finally, the Weymouth Wetlands
    Protection      Ordinance          ("Weymouth       WPO")    generally     requires     a
    developer     to     obtain    a    permit    from     the   Weymouth     Conservation
    Commission before construction can begin in a wetlands area.
    1Algonquin does not claim in this action that the statewide,
    minimum requirements of the Massachusetts WPA are preempted as
    applied to the compressor station.
    - 4 -
    Weymouth, Mass., Code § 7-301(b).         The Weymouth WPO gives the
    Conservation Commission the authority to impose permit conditions
    or deny an application in its entirety if it finds the project
    will not meet Conservation Commission performance standards or
    regulations.   Id. § 7-301(k).
    B.
    Algonquin is a natural-gas transmission company that is
    headquartered in Houston, Texas.     In response to rising demand for
    natural gas, Algonquin's proposed "Atlantic Bridge Project" aims
    to increase the delivery capacity of its existing natural-gas
    transmission system in the northeastern United States.         Algonquin
    seeks to construct a new compressor station -- an appurtenance
    that is placed alongside a gas pipeline to maintain pressure and
    gas-flow rates -- in Weymouth, Massachusetts as part of this
    project.   The proposed site is located within and adjacent to a
    wetlands area.     It is also situated in a coastal zone subject to
    Massachusetts' coastal-management program.
    In October 2015, Algonquin applied to FERC for a CPCN to
    construct and operate the Atlantic Bridge Project.     FERC completed
    an environmental assessment of the proposed project pursuant to
    the National Environmental Policy Act ("NEPA"), see generally 
    42 U.S.C. § 4332
    (C); 
    40 C.F.R. § 1501.4
    , in which it found that the
    proposal   would    have   no    significant   environmental     impact.
    Subsequently, on January 25, 2017, FERC issued Algonquin the CPCN.
    - 5 -
    See Algonquin Gas Transmission, LLC Mars. & Ne. Pipeline, LLC
    (Algonquin), 
    158 FERC ¶ 61,061
    , 
    2017 WL 383829
    , at *1 (Jan. 25,
    2017).     Significant to this appeal, FERC's CPCN requires that
    Algonquin obtain a "determination of consistency with the [CZMA]"
    from Massachusetts OCZM "[p]rior to construction of the Weymouth
    Compressor Station."       
    Id. at *64
    .
    By the time Algonquin received the CPCN from FERC, it
    had already applied for several Commonwealth authorizations needed
    to obtain a determination of consistency from Massachusetts OCZM.
    Pursuant to the Massachusetts WPA and the Weymouth WPO, Algonquin
    sought authorization from the Weymouth Conservation Commission to
    begin     construction.          The     Conservation       Commission     denied
    Algonquin's WPA and WPO permit applications.                    It found that
    Algonquin had not sufficiently addressed hurricane and explosion
    risks associated with the project.                 It also concluded that a
    Weymouth    WPO   permit   could       not   be   adequately   conditioned     to
    sufficiently mitigate the air, water, aesthetic, and recreational
    impairments that would result from construction and operation of
    the facility.
    MassDEP has ultimate authority over Algonquin's WPA
    application,      so   Algonquin   appealed       Weymouth's   WPA    denial   to
    MassDEP, seeking a superseding order of conditions.                  In a series
    of rulings and orders, MassDEP agreed with Algonquin and reversed
    the      Massachusetts     WPA     permit         denial.       But      Weymouth
    - 6 -
    administratively appealed that reversal, pursuant to 310 Mass.
    Code Regs. § 10.05(7)(j)(2), and MassDEP stayed the adjudication
    of   Weymouth's        appeal    (and    thus      the   finalization     of    the   WPA
    authorization)         until    a    court     determines      whether    federal     law
    preempts Weymouth's denial of the project under the Weymouth WPO.
    Massachusetts OCZM has yet to issue a consistency determination
    for the proposed project and maintains that it cannot do so until
    Algonquin       proffers       all    relevant       Commonwealth      authorizations,
    including a final Massachusetts WPA permit.2
    To summarize:          FERC has concluded its proceedings and
    has issued Algonquin a permit that is conditioned on receipt of a
    CZMA        consistency        determination          from     Massachusetts      OCZM;
    Massachusetts OCZM will not issue its determination until MassDEP
    conclusively rules in favor of Algonquin on Weymouth's challenge
    to the Massachusetts WPA approval; and MassDEP will not dispose of
    that       challenge   until     a    court    (or     FERC)   resolves    Algonquin's
    preemption challenge to the application of Weymouth's ordinance to
    the compressor station.
    Thus    matters       stood    on     May 4,    2017,   when    Algonquin
    commenced this action in federal district court against the Town
    2
    Weymouth holds the position that MassDEP's stay is not an
    impediment to Algonquin's receipt of a consistency determination
    from Massachusetts OCZM. However, as will be addressed, infra,
    Massachusetts OCZM appears to require the submission of a final
    Massachusetts WPA permit, when applicable, before completing its
    CZMA review.

    of Weymouth and the Weymouth Conservation Commission (collectively
    "Weymouth"), seeking a declaratory judgment that the construction
    and operation of the Weymouth Compressor Station is not subject to
    the Weymouth WPO and enjoining enforcement of the permit denial
    because the ordinance, as it applies to the compressor station, is
    preempted under federal law.      The district court entered summary
    judgment for Algonquin, relying on both field preemption and
    conflict   preemption   grounds    in     doing   so.   Algonquin   Gas
    Transmission, LLC v. Weymouth Conservation Comm'n, No. 17-10788-
    DJC, 
    2017 WL 6757544
    , at *5–7 (D. Mass. Dec. 29, 2017). Weymouth's
    appeal followed.
    II.
    Weymouth advances two reasons why we should reverse the
    district court's entry of summary judgment for Algonquin.       First,
    it argues that the district court erred in not finding this action
    to be time-barred.   Second, as to the merits, Weymouth argues that
    application of its ordinance to the proposed compressor station is
    not foreclosed by federal law under theories of conflict and field
    preemption.   We consider each argument in turn.
    A.
    When a federal statute creates a cause of action for
    damages or other legal relief but provides no applicable statute
    of limitations, "we generally 'borrow' the most closely analogous
    state limitations period."   Graham Cty. Soil & Water Conservation
    - 8 -
    Dist. v. U.S. ex rel. Wilson, 
    545 U.S. 409
    , 414 (2005) (citing N.
    Star Steel Co. v. Thomas, 
    515 U.S. 29
    , 33–34 (1995)); see also
    Agency Holding Corp. v. Malley-Duff & Assocs., Inc., 
    483 U.S. 143
    ,
    147 (1987) (observing that "the Rules of Decision Act, 
    28 U.S.C. § 1652
    , requires application of state statutes of limitations
    unless 'a timeliness rule drawn from elsewhere in federal law
    should be applied.'" (quoting DelCostello v. Teamsters, 
    462 U.S. 151
    , 159 n.13 (1983))).           Weymouth urges us to apply this general
    rule to Algonquin's preemption claim and to look to Massachusetts'
    certiorari     statute,     
    Mass. Gen. Laws ch. 249, § 4
    ,   for   the
    applicable     statute      of   limitations.           The   certiorari     statute
    provides sixty days to correct errors in a judicial or quasi-
    judicial proceeding that is not otherwise reviewable.                       See id.;
    City of Revere v. Mass. Gaming Comm'n, 
    71 N.E.3d 457
    , 467 (Mass.
    2017).        Were   we   to     adopt   Weymouth's       position,     Algonquin's
    preemption claim would be time-barred because Algonquin filed this
    action   in    May   2017   --    nearly    a    year    after   the   Conservation
    Commission's WPO permit denial.
    This general borrowing rule upon which Weymouth relies
    has an important exception.               In equitable suits arising under
    federal law, we normally do not borrow a limitations period from
    state law.     See Holmberg v. Armbrecht, 
    327 U.S. 392
    , 395–96 (1946)
    ("Traditionally and for good reasons, statutes of limitation are
    not controlling measures of equitable relief."); Russell v. Todd,
    - 9 -
    
    309 U.S. 280
    , 287 (1940) ("The Rules of Decision Act does not apply
    to suits in equity."); Union Carbide Corp. v. State Bd. of Tax
    Comm'rs, 
    992 F.2d 119
    , 122–23 (7th Cir. 1993); see also Reed v.
    United Transp. Union, 
    488 U.S. 319
    , 324 (1989) (citing Holmberg
    with approval).        Instead, the doctrine of laches applies.                       See
    Russell, 
    309 U.S. at 287
    .
    This exception for equitable actions is subject to one
    caveat:   Sometimes a claim for equitable relief is pursued to
    vindicate a legal right.            For example, federal law may create a
    legal right subject to enforcement at both law (for damages) and
    equity.   In such a case, the limitations period applicable to the
    claim at law may be applied to the equitable claim as well.                           See
    Cope v. Anderson, 
    331 U.S. 461
    , 464 (1947) ("[E]quity will withhold
    its   relief   in    such    a    case    where    the   applicable         statute    of
    limitations would bar the concurrent legal remedy."); Russell, 
    309 U.S. at 289
    .     Algonquin, however, brings no equitable sibling of
    a   concurrent      claim    at    law.      Rather,      it     solely     pursues     a
    freestanding     federal         equitable    claim      unassociated        with     any
    concurrent federal legal remedy that might supply (either directly
    or by borrowing) any limitations period.
    Weymouth's      briefs       nevertheless         seem    to    argue     by
    implication     that   the       Massachusetts     certiorari         statue   is     the
    applicable     concurrent        legal    remedy   to    which    we   should       look.
    However, we have found no case holding that a state legal remedy
    - 10 -
    is the concurrent remedy at law for an equitable claim brought
    under federal law, and for good reason:             Such a holding would run
    counter to the principle that claims are "concurrent" when "the
    only difference between [them] is the relief sought."                 Grynberg v.
    Total S.A., 
    538 F.3d 1336
    , 1353 (10th Cir. 2008).                 Moreover, the
    very purpose of the concurrent-legal-remedy doctrine is "[t]o
    prevent   plaintiffs      from    making   a    mockery    of   the   statute    of
    limitations   by    the     simple   expedient     of     creative    labelling."
    Gilbert v. City of Cambridge, 
    932 F.2d 51
    , 57 (1st Cir. 1991).
    Filing a well-recognized federal claim rather than a state-law
    claim cannot be fairly described as claim relabeling; rather, it
    is the selection of one claim instead of another within the context
    of a dual-sovereign system.
    That Algonquin also requests declaratory relief pursuant
    to the Declaratory Judgment Act, 
    28 U.S.C. § 2201
    , does not vitiate
    the   equitable    nature    of   its   suit.      To   "ascertain     whether   a
    particular suit for declaratory relief is grounded in law or in
    equity," we ask "whether, in the absence of the Declaratory
    Judgment Act, the suit brought would have been legal or equitable
    in nature."   El Dia, Inc. v. Hernandez Colon, 
    963 F.2d 488
    , 493
    (1st Cir. 1992) (quoting Mowbray v. Moseley, Hallgarten, Estabrook
    & Weeden, Inc., 
    795 F.2d 1111
    , 1114–15 (1st Cir. 1986)).                     Were
    declaratory relief unavailable to Algonquin, Algonquin would be
    left to pursue its negative injunction, premised on its claim that
    - 11 -
    federal law "immunizes" it from local regulation, see Armstrong v.
    Exceptional Child Ctr., Inc., 
    135 S. Ct. 1378
    , 1384 (2015), as its
    only federal means of redress.       For this reason, Algonquin's
    requested declaratory relief is also grounded in equity.    Hence,
    we apply laches.
    Laches arguably might have barred Algonquin's preemption
    claim if Weymouth had shown that Algonquin lacked reasonable
    diligence in pursuing its federal rights to Weymouth's prejudice.
    See K-Mart Corp. v. Oriental Plaza, Inc., 
    875 F.2d 907
    , 911 (1st
    Cir. 1989) (citing Puerto Rican–Am. Ins. Co. v. Benjamin Shipping
    Co., 
    829 F.2d 281
    , 283 (1st Cir. 1987)).     However, Weymouth has
    made no argument on appeal that laches should foreclose our
    consideration of Algonquin's suit.    And though Weymouth maintains
    that Algonquin could have raised its preemption claim sooner, it
    does not contend that Algonquin's delay was unreasonable or that
    it prejudiced Weymouth in any way.     Thus, we deem this argument
    waived.   See Rife v. One W. Bank, F.S.B., 
    873 F.3d 17
    , 19 (1st
    Cir. 2017) ("It is well-settled that arguments not raised in an
    opening brief . . . are deemed waived.").     And even were it not
    waived, nothing in the record before us indicates a lack of
    diligence on Algonquin's part or any prejudice to Weymouth.
    Accordingly, we affirm the district court's finding that
    Algonquin's preemption claim is not time-barred.
    - 12 -
    B.
    The   district     court      relied    on   field       preemption    and
    conflict preemption principles in entering summary judgment for
    Algonquin.    See Algonquin Gas Transmission, LLC, 
    2017 WL 6757544
    ,
    at *5–7. Weymouth maintains that neither form of preemption should
    preclude     the   application       of    its     ordinance     to    the   Weymouth
    Compressor Station.        Before we reach the merits of this issue,
    however, we first consider whether Algonquin's preemption claim is
    ripe for our review.
    1.
    "[T]he question of ripeness may be considered on a
    court's own motion."       Nat'l Park Hosp. Ass'n v. Dep't of Interior,
    
    538 U.S. 803
    , 808 (2003).                 We do so now and, after careful
    consideration,      we   find   Algonquin's         preemption    claim      ripe   for
    judicial resolution.
    In determining whether an issue is ripe for our review,
    we consider "(1) the fitness of the issues for judicial decision
    and   (2) the      hardship     to   the        parties   of   withholding      court

    - 13 -
    to ask "whether the claim involves uncertain and contingent events
    that may not occur as anticipated or may not occur at all," thus
    rendering any opinion we might offer advisory.             Ernst & Young v.

    development."       Ernst & Young,

    the hardship prong of this inquiry is purely prudential and
    requires that we evaluate "whether the challenged action creates
    a 'direct and immediate' dilemma for the parties."               W.R. Grace &

    In City of Fall River, Massachusetts v. FERC, we found
    a challenge to a FERC permit not ripe when the permit made the
    commencement    of     construction   contingent     on    the    receipt   of
    authorizations from two other federal agencies.            
    507 F.3d 1
    , 4–5,
    7–8 (1st Cir. 2007).       In that case, it was uncertain whether the
    approved work would be forthcoming because both agencies had
    withheld approval and "ha[d] expressed serious reservations about
    the project."        
    Id. at 7
    .    Thus, we found it likely that our
    - 14 -
    resolution of the challenge to FERC's conditional approval "would
    be advisory" and "irrelevant to the ultimate approvability of the
    project."    
    Id. at 8
    .
    In this case, FERC's certificate also makes construction
    contingent upon the approval of another agency.            See Algonquin,
    
    2017 WL 383829
    , at *64 ("Prior to construction of the Weymouth
    Compressor Station, Algonquin shall file with the Secretary a copy
    of [Massachusetts OCZM's] determination of consistency with the
    Coastal Zone Management Act.").         Unlike Fall River, however, this
    case does not involve a challenge to the conditioned permit itself.
    Rather,   Algonquin   seeks    relief    that   would   finally   remove   a
    principal impediment that stands in the way of a final action by
    that other agency.3      Moreover, Massachusetts OCZM has expressed no
    serious reservation about issuing a determination of consistency
    -- at least as far as we can tell based on the record before us -
    - and MassDEP's initial decision to grant Algonquin a Massachusetts
    3 Weymouth disputes that the stay of its challenge to
    MassDEP's superseding order of conditions is an impediment to
    Algonquin's   receipt   of  a   consistency   determination   from
    Massachusetts OCZM. However, Massachusetts OCZM maintains that it
    "cannot complete its review and issue a decision of consistency
    with its enforceable program policies until all applicable
    licenses, permits, certifications and other authorizations have
    been issued by Massachusetts environmental agencies." And it is
    not contested that the Massachusetts WPA is such an enforceable
    policy under Massachusetts' coastal-management program.         It
    follows that MassDEP must complete its adjudication of Weymouth's
    challenge before Massachusetts OCZM will complete its CZMA review.
    - 15 -
    WPA permit indicates that a final disposition in Algonquin's favor
    is, while not preordained, at least likely.                  Accordingly, our
    resolution    of   Algonquin's   preemption       claim    would   be   neither
    "advisory" nor "irrelevant"; rather, it would apparently clear a
    procedural logjam that would not otherwise be cleared.                       See
    Weaver's Cove Energy, LLC v. R.I. Coastal Res. Mgmt. Council, 
    589 F.3d 458
    , 468–69 (1st Cir. 2009) (finding the final resolution of
    "barriers to ultimate approval of the project" sufficient to
    warrant our exercise of jurisdiction).
    For these reasons, we find Algonquin's challenge to be
    ripe.
    2.
    Algonquin urges us to hold, in accordance with the
    district court's decision, that the NGA itself preempts the field
    of   regulation    that   includes    any     material    application   of   the
    Weymouth WPO to Algonquin's Atlantic Bridge Project.               We decline
    to go so far, preferring to decide the preemption issue on narrower
    grounds, that of conflict preemption.            See Weaver's Cove Energy,
    LLC, 589 F.3d at 472. Conflict preemption exists when "'compliance
    with both state and federal law is impossible,' or where 'the state
    law "stands as an obstacle to the accomplishment and execution of
    the full purposes and objectives of Congress."'"               Oneok, Inc. v.
    Learjet, Inc., 
    135 S. Ct. 1591
    , 1595 (2015) (quoting California v.
    ARC Am. Corp., 
    490 U.S. 93
    , 100, 101 (1989)).                  We review the
    - 16 -
    district court's preemption decision de novo.                          Weaver's Cove
    Energy, LLC, 589 F.3d at 472.
    Though the NGA itself does not expressly provide for a
    comprehensive     regulatory      scheme    pursuant        to    which   FERC    must
    consider environmental, siting, and safety factors when issuing a
    CPCN, FERC's regulations implementing that statute do provide such
    a scheme.     Prior to authorization, FERC is required to prepare an
    environmental assessment under NEPA, 
    18 C.F.R. § 380.5
    (b)(1); see
    also 
    42 U.S.C. § 4332
    ; 
    40 C.F.R. § 1508.9
    .                        An environmental
    assessment      must    discuss     "the    need    for     the    proposal, . . .
    alternatives     [to    the   project], . . .        [and]       the   environmental
    impacts of the proposed action and alternatives."                            
    40 C.F.R. § 1508.9
    (b).       In     addition,    an   environmental         assessment      must
    include an analysis determining whether a full-blown environmental
    impact statement must be prepared and whether the project will
    have a significant environmental impact. 
    Id.
     § 1508.9(a)(1). This
    process entails FERC taking a close look at the "intensity" of the
    project's environmental consequences, including "[t]he degree to
    which   the    proposed    action     affects      public    health     or    safety,"
    "proximity to . . . wetlands," the extent to which "the possible
    effects on the human environment are highly uncertain or involve
    unique or unknown risks," and "[w]hether the action threatens a
    violation of Federal, State, or local law or requirements imposed
    for the protection of the environment."               
    40 C.F.R. § 1508.27
    (b).
    - 17 -
    In addition, FERC's regulations require a developer to
    include in its application for a CPCN "all information necessary
    to advise [FERC] fully concerning the . . . construction . . . for
    which a certificate is requested."         
    18 C.F.R. § 157.5
    (a).       This
    includes information detailing the location and size of a proposed
    facility and environmental reports detailing the projected local
    and environmental consequences of the project.            See 
    18 C.F.R. § 157.14
    (a)(6)–(7).        Specifically, these environmental reports
    must identify the wetlands that will be affected and available
    mitigation measures, 
    id.
     § 380.12(d)–(e), the land use, public
    health, safety, and aesthetic consequences of the project, id.
    § 380.12(j), and any air quality impacts the proposal might have,
    id. § 380.12(k).         Then, pursuant to FERC's Certificate Policy
    Statement, FERC determines whether a project is in the public
    convenience and necessity by "balanc[ing] the public benefits
    against the potential adverse consequences."       Certification of New
    Interstate Nat. Gas Pipeline Facilities,

     (2000).      This balancing weighs the economic vitality
    of the project and any adverse effects on existing customers before
    proceeding    to   "an    independent   environmental   review"   of    the
    project, whereby FERC considers the NEPA analysis, "the other
    interests of landowners and the surrounding community," potential
    "route[s] other than the one proposed by the applicant," and the
    - 18 -
    goal of avoiding "unnecessary disruptions of the environment."
    
    Id. ¶¶ 61,737
    ; 61,745; 61,749.
    Pursuant   to    this      process,   FERC    --   in   both   its
    environmental assessment and its CPCN -- considered essentially
    the same environmental and safety concerns that the Conservation
    Commission relied upon in denying Algonquin a Weymouth WPO permit.
    FERC's environmental analysis addressed water resources, wetlands,
    land use, recreational, air quality, and safety considerations
    associated with the Atlantic Bridge Project and the Weymouth
    Compressor Station.       See Algonquin, 
    2017 WL 383829
    , at *10.            And
    in its CPCN, FERC specifically addressed environmental justice,
    aesthetic, and air quality concerns regarding the siting of the
    compressor station but found such impacts either not significant
    or adequately addressable.        
    Id.
     at *23–24, 37–39.         The CPCN also
    considered risks from flooding and impacts from hurricanes but
    concluded that the station's proposed design would minimize these
    risks. 
    Id.
     at *26–27. It further concluded that the project would
    have no direct impact on water resources or nearby wetlands since
    no dredging or in-water construction at the Weymouth site would be
    required.     
    Id.
     at *30–34.     Finally, as to risks from a potential
    explosion, FERC's CPCN noted that Algonquin has committed to comply
    with   all   applicable      Pipeline    and   Hazardous   Materials    Safety
    Administration regulations, thereby minimizing any such risk.               
    Id. at *53
    .
    - 19 -
    Based on its economic and environmental review, and its
    finding that there was no better site for the Weymouth Compressor
    Station, 
    id. at *26
    , FERC concluded that its construction and
    operation would serve the public interest, 
    id.
     at *5–6.                        The
    Conservation Commission's order reaches the opposite conclusion
    based on essentially the same environmental considerations.                   In so
    doing, the Conservation Commission's permit denial certainly poses
    a significant obstacle, indeed an effectively complete obstacle,
    to FERC's ultimate determination that "public convenience and
    necessity"      "require"   that   the   Weymouth      Compressor    Station    be
    built.    15 U.S.C. § 717f(e) (emphasis added).            Accordingly, FERC's
    issuance of a CPCN to Algonquin in this case conflict preempts the
    Conservation Commission's WPO permit denial.               See Oneok, Inc., 135
    S. Ct. at 1595.
    Weymouth seeks to avoid this result by arguing that
    Algonquin breached a duty to "make a reasonable attempt to obtain
    an   approval      before   asserting    that    the    local     authority    has
    'prohibited' the project."         Weymouth provides no support for the
    existence of such a duty under federal law.                 To the extent that
    Weymouth makes this argument in reliance on the portion of FERC's
    certificate      that   "encourages      cooperation       between   interstate
    pipelines    and    local   authorities,"      Algonquin,     
    2017 WL 383829
    ,
    at *12,    we    note   that   this   provision     does    not    require    such
    cooperation from Algonquin; it merely "encourages" it, perhaps to
    - 20 -
    the satisfaction of FERC.4    But nothing in the FERC certificate or
    any federal law to which Weymouth points would allow us to forgo
    our preemption ruling on the basis that Algonquin did not try hard
    enough to convince Weymouth to allow the project to proceed.
    Weymouth also passingly invokes the doctrine of unclean
    hands to suggest that we should decline to grant the declaratory
    and injunctive relief that Algonquin seeks in this case.              See
    generally Texaco P.R., Inc. v. Dep't of Consumer Affairs, 
    60 F.3d 867
    , 880 (1st Cir. 1995).      But even assuming (without deciding)
    that Algonquin somehow owed an enforceable duty to Weymouth to
    seek Weymouth's approval of the project under its ordinance,
    Weymouth points to no evidence in the record to support its
    proposition that Algonquin pursued a WPO permit in less than good
    faith.5
    Weymouth   also    argues   that   FERC's   CPCN   cannot   have
    preemptive effect in this case due to its "conditional" nature.
    We reject this argument for essentially the same reasons we found
    this dispute to be ripe. FERC has conclusively and finally weighed
    4 If Weymouth means to raise a lack of cooperation as a
    collateral challenge to Algonquin's compliance with FERC's
    certificate, that issue is not before us.
    5 On this point, Weymouth argues that entry of summary
    judgment for Algonquin would be inappropriate before discovery has
    been conducted.    Weymouth, though, did not move to defer the
    district court's consideration of the summary judgment motion to
    allow for discovery pursuant to Fed. R. Civ. P. 56(d).
    - 21 -
    the environmental, safety, and siting considerations associated
    with this project in its CPCN, and FERC's determination that the
    project is necessary and in the public interest is at this point
    only "conditional" in that it awaits the conclusion of MassDEP's
    proceeding and a consistency determination from Massachusetts
    OCZM, both of which, in turn, hinge on our preemption decision.
    Whether and to what extent the FERC permit is otherwise conditioned
    we need not decide.          Likely for similar, albeit unstated reasons,
    we have, in at least one instance, readily assumed that FERC
    approvals       containing    similar   conditions   precedent    still   have
    preemptive force.       See Weaver's Cove Energy, LLC, 589 F.3d at 472-
    474.6       And the D.C. Circuit has applied this same assumption.        See,
    e.g., Myersville Citizens for a Rural Cmty., Inc. v. FERC, 
    783 F.3d 1301
    , 1308, 1319–22 (D.C. Cir. 2015); Dominion Transmission,
    Inc. v. Summers, 
    723 F.3d 238
    , 245 (D.C. Cir. 2013).             On the other
    side of the ledger, Weymouth directs us to no case holding that
    such a FERC authorization -- final in all respects aside from
    6
    Weymouth argues that Weaver's Cove is inapposite because
    concurrence with the state's coastal-management program could be
    presumed for the court's preemption analysis there. This ignores
    the fact that the Weaver's Cove project required additional
    authorizations before construction could commence, including one
    from the Army Corps of Engineers under the Rivers and Harbors Act,
    
    33 U.S.C. § 403
    , which Weaver's Cove had not yet obtained at the
    time of appeal. See Weaver's Cove Energy, LLC, 589 F.3d at 463,
    468. Our decision in that case also noted an amendment to the
    original plan that required additional "federal regulatory
    approval" before construction could begin. See id. at 468.
    - 22 -
    requiring the applicant to obtain additional approvals prior to
    commencing construction -- lacks the ability to preempt contrary
    state or local law.
    With these considerations in mind, we hold that FERC's
    CPCN conflict preempts the Conservation Commission's WPO permit
    denial.
    III.
    For   the   foregoing    reasons,    we    affirm   the   district
    court's entry of summary judgment for Algonquin to the extent that
    it held that FERC's issuance of a CPCN authorizing construction of
    the   Weymouth   Compressor   Station      conflict   preempts   Weymouth’s
    application of its ordinance to Algonquin's FERC-approved project.
