    OPINION OF THE COURT
    ____________
    HARDIMAN, Circuit Judge.
    The Port Authority of New York and New Jersey
    (Authority) appeals the District Court‘s summary judgment,
    which orders the Authority to make modifications to its
    Grove Street Station to bring it into compliance with the
    Americans with Disabilities Act (ADA) of 1990, Pub. L. No.
    101-336, 
    104 Stat. 378
     (codified as amended at 
    42 U.S.C. §§ 12101
    –12213). We will vacate this judgment and remand
    the case for further proceedings. In a cross-appeal, Plaintiffs
    Heightened Independence and Progress, Inc. (hip), the United
    Spinal Association, and Peter Gimbel appeal the District
    Court‘s order dismissing their state-law claims on the basis
    that allowing such claims to proceed would violate the
    interstate compact between New York and New Jersey that
    3
    created the Authority. That order of the District Court will be
    affirmed.
    I
    A
    The Authority‘s wholly owned subsidiary, the Port
    Authority Trans-Hudson Corporation (PATH), operates the
    Grove Street Station in Jersey City, New Jersey, which is the
    subject of this lawsuit. The Station has three levels—street,
    mezzanine, and platform—and two street-level entrance
    sides—east and west. The Station can serve an eight-car
    train. The mezzanine is not connected between the east and
    west sides. One staircase connects the east mezzanine to a
    platform-level corridor, which leads out to the platform itself.
    The Station was built in 1910, and in the 1970s PATH
    closed the east entrance and constructed two entrances on the
    west side. As reflected in a 2001 report, in 2000 PATH
    planned to expand the Station to accommodate ten-car trains
    and persons with disabilities, a project that would have
    involved the construction of a new entrance and two elevators
    on the west side. After September 11, 2001, and the resulting
    closure of two of the Authority‘s stations—Exchange Place in
    New Jersey and World Trade Center in Manhattan—ridership
    increased at the Grove Street Station. Citing concerns about
    congestion and safety, PATH scrapped its renovation plans
    and undertook a different ―fast track‖ project to reopen the
    east entrance.
    Construction began in 2002 and concluded in 2005.
    The project involved building a new street-level pavilion and
    focused on renovating the connections between the street and
    4
    mezzanine levels on the east side only. The pavilion was
    built four inches above the sidewalk to comply with flood-
    plain construction requirements, and stairs were installed to
    connect the sidewalk and the building, which is also referred
    to as a ―headhouse.‖ The mezzanine was expanded to include
    a new fare-collection area. In addition, the platform corridor
    was reopened and the interior spaces connecting the three
    levels were rehabilitated. To complete the project, PATH
    purchased land adjacent to the Station from a private
    company.
    In 2006, after PATH had finished construction, its
    engineering department concluded that elevator installation
    was feasible only on the west side of the Station. PATH
    believed that the east-side platform would be too crowded
    with an elevator, leading to safety concerns, and that
    construction on the east side would result in service
    disruption and possible flooding.
    B
    Plaintiffs filed this lawsuit in state court in 2007, and
    the Authority removed the case to the District Court. The
    complaint alleges that the Grove Street Station renovations
    triggered an obligation under the ADA to make the Station
    accessible to handicapped persons. It also alleges violations
    under New Jersey‘s Law Against Discrimination and certain
    New Jersey construction code provisions. The District Court
    dismissed the state-law claims, reasoning that, under the
    terms of the interstate compact that created the Authority, one
    state cannot unilaterally regulate the joint entity. See hip, Inc.
    v. Port Auth. of N.Y. & N.J. (hip I), No. 07-2982, 
    2008 WL 852445
    , at *4–6 (D.N.J. Mar. 28, 2008). Following further
    5
    proceedings and failed settlement attempts, the parties filed
    cross-motions for summary judgment.
    The District Court entered summary judgment for
    Plaintiffs. During discovery, five schemes for making the
    east entrance ADA-compliant were produced, and the
    Authority‘s engineering department evaluated each of those
    schemes. The Court held that of the five, two—Schemes 4
    and 5, which propose installation of a mezzanine-to-platform
    Limited Use Limited Access (LULA) elevator—are feasible.
    Consequently, the Court ordered the Authority to make the
    east entrance accessible. hip, Inc. v. Port Auth. of N.Y. & N.J.
    (hip II), No. 07-2982, 
    2011 WL 3957532
    , at *3–5 (D.N.J.
    Sept. 6, 2011). The parties timely filed notices of appeal.
    II
    The ADA is a complex law codified in numerous
    statutes in the United States Code. Regulations have been
    promulgated by the Department of Transportation to
    implement those statutes. And pursuant to 
    42 U.S.C. § 12204
    , the Architectural and Transportation Barriers
    Compliance Board has issued a set of ADA Accessibility
    Guidelines (ADAAG). The Department of Justice produces
    an ADA ―technical assistance manual,‖ which provides still
    further guidance. The litigants here dispute the interpretation
    of several of these provisions as applied to the Grove Street
    Station construction project.
    For example, and as a preliminary matter, the
    regulations and the ADAAG impose different obligations on
    different kinds of construction projects. ―New facility‖
    construction is distinguished from the ―alteration‖ of existing
    facilities. See 
    49 C.F.R. §§ 37.41
    , 37.43; ADAAG §§ 4.1.3,
    6
    4.1.6; Regents of Mercersburg Coll. v. Republic Franklin Ins.
    Co., 
    458 F.3d 159
    , 168–69 (3d Cir. 2006). The ADAAG also
    recognizes another category of construction, ―addition,‖
    though it treats additions largely as alterations. ADAAG
    § 4.1.5. Generally, the ADA is more onerous on new
    construction projects than it is on alterations.
    The District Court treated the Station renovations as an
    alteration but recognized that they ―may also qualify as new
    construction and/or addition.‖ hip II, 
    2011 WL 3957532
    , at
    *3. On appeal, Plaintiffs urge application of the new-
    construction rules, arguing that the ―headhouse‖ is an entirely
    new structure. We reject this argument for two reasons.
    First, Plaintiffs‘ notice of appeal unambiguously specifies
    only the District Court‘s dismissal order, and not its summary
    judgment. See Fed. R. App. P. 3(c)(1)(B) (―The notice of
    appeal must . . . designate the judgment, order, or part thereof
    being appealed . . . .‖). In fact, the notice of appeal indicates
    it appeals the dismissal order only ―insofar as the order
    dismisses with prejudice the New Jersey state law claims
    raised in the Complaint.‖ (JA 5.) Although there are
    circumstances under which we may review an order not
    specified in the notice of appeal, none is present in this
    appeal. See Sulima v. Tobyhanna Army Depot, 
    602 F.3d 177
    ,
    184 (3d Cir. 2010). While we have jurisdiction to review the
    summary judgment because the Authority has appealed that
    order, we will not entertain Plaintiffs‘ challenge to an order
    from which they failed to appeal.
    Second, we think the District Court‘s characterization
    of the construction project as an alteration was sound. The
    regulations clearly distinguish between new construction and
    alterations, and because the obligations of the builder under
    each scheme are different, a given construction project must
    7
    be classified as one or the other. An alteration is ―a change to
    an existing facility, including, but not limited to, remodeling,
    renovation, rehabilitation, reconstruction, historic restoration,
    changes or rearrangement in structural parts or elements, and
    changes or rearrangement in the plan configuration of walls
    and full-height partitions.‖ 
    49 C.F.R. § 37.3
    . The Grove
    Street Station project plainly falls under this definition, and it
    would be a stretch to claim that the Station, which existed in
    substantially the same form and for the same purpose prior to
    the renovation, is a new facility. Moreover, the modifications
    clearly exceeded the scope of the definitional exclusions from
    ―alteration,‖ such as ―[n]ormal maintenance, reroofing,
    painting or wallpapering,‖ because ―they affect[ed] the
    usability of the building or facility.‖ 
    Id.
     Accordingly, in this
    case we will apply only the ADA provisions applicable to
    alterations.
    As noted, this case comes to us on the appeal of an
    order resolving cross-motions for summary judgment.
    ―When reviewing a district court‘s summary judgment
    decision in an ADA case, we exercise plenary review,
    applying the same standard as the district court.‖ Sulima, 
    602 F.3d at
    184 (citing Turner v. Hershey Chocolate USA, 
    440 F.3d 604
    , 611 (3d Cir. 2006)). ―Summary judgment is
    appropriate if, viewing the record in the light most favorable
    to the non-moving party, there are no genuine issues of
    material fact and the moving party is entitled to judgment as a
    matter of law.‖ Id.; accord Fed. R. Civ. P. 56(a). In
    considering Plaintiffs‘ and the Authority‘s motions, we must
    ―construe[] facts and draw[] inferences in favor of the party
    8
    against whom the motion under consideration is made.‖1 J.S.
    ex rel. Snyder v. Blue Mountain Sch. Dist., 
    650 F.3d 915
    , 925
    (3d Cir. 2011) (en banc) (internal quotation marks omitted).
    III
    The touchstone of our analysis in this appeal is the
    Authority‘s obligation—triggered because it altered the
    Station—to make the Station accessible ―to the maximum
    extent feasible.‖ This requirement appears in 
    42 U.S.C. § 12147
    (a) and 
    49 C.F.R. § 37.43
    (a)(1), as well as in the
    ―technical infeasibility‖ guideline, ADAAG § 4.1.6(1)(j),
    which is discussed in greater detail below.
    As used in this section, the phrase to the
    maximum extent feasible applies to the
    occasional case where the nature of an existing
    facility makes it impossible to comply fully
    with applicable accessibility standards through
    a planned alteration. In these circumstances, the
    entity shall provide the maximum physical
    accessibility feasible. Any altered features of
    1
    We have appellate jurisdiction to review the denial of
    a motion for summary judgment where a cross-motion has
    been granted. Levy v. Sterling Holding Co., 
    544 F.3d 493
    ,
    501 & n.6 (3d Cir. 2008); see 
    28 U.S.C. § 1291
    . The District
    Court had subject-matter jurisdiction pursuant to 
    28 U.S.C. §§ 1331
    , 1343, and 1367.
    9
    the facility or portion of the facility that can be
    made accessible shall be made accessible. If
    providing accessibility to certain individuals
    with disabilities (e.g., those who use
    wheelchairs) would not be feasible, the facility
    shall be made accessible to individuals with
    other types of disabilities (e.g., those who use
    crutches, those who have impaired vision or
    hearing, or those who have other impairments).
    
    49 C.F.R. § 37.43
    (b). Where we discuss ―feasibility‖ in this
    opinion, we do so only for the sake of expedience,
    recognizing that the actual standard—―to the maximum extent
    feasible‖—is much more demanding.
    Having discerned the appropriate regulatory
    framework that governs this appeal, we turn to the substantive
    disputes. The Authority proffers five reasons why it is
    entitled to summary judgment or, alternatively, summary
    judgment was wrongly entered for Plaintiffs. Two of these
    arguments—that the ADA did not require the Authority to
    make the platform accessible because it was not an ―altered
    portion[]‖ of the facility, 
    42 U.S.C. § 12147
    (a), and that the
    Authority was excused from making ADA-compliant
    modifications because the cost of those changes would have
    been disproportionate, 
    49 C.F.R. § 37.43
    (e)–(f)—were not
    preserved in the District Court, so we will not consider them
    10
    here.2 Tri-M Grp., LLC v. Sharp, 
    638 F.3d 406
    , 416 (3d Cir.
    2011). That leaves three of the Authority‘s arguments for us
    to resolve: first, the accessibility modifications ordered by the
    District Court could not have been accomplished because
    they would require the acquisition of subterranean property
    rights currently owned by Jersey City; second, the ordered
    modifications would have been ―technically infeasible‖ under
    ADAAG § 4.1.6(1)(j), or, in the alternative, there are triable
    factual disputes regarding technical infeasibility; and third,
    the ordered modifications would not have been feasible
    because, if implemented, the Station might not have complied
    with National Fire Protection Association Standard 130
    (NFPA 130), a fire-safety code the Authority has adopted.
    We hold that neither side is entitled to summary judgment on
    these issues.
    2
    We note that were we to exercise our discretion to
    reach these unpreserved arguments, we would be unlikely to
    find either persuasive. Even the most cursory glance at the
    joint appendix‘s before-and-after photos of the platform-level
    tunnel and staircase indicates that the platform was part of the
    altered area, as those areas were clearly rehabilitated.
    Because the platform is part of the altered area, the ―path of
    travel‖ disproportionate-cost limitations, see 
    49 C.F.R. § 37.43
    (e)(1), (f)(1); ADAAG § 4.1.6(2), do not apply.
    Additionally, the Authority has provided only estimates of the
    costs of implementing Schemes 4 or 5 now, and not how
    much those schemes would have cost if implemented during
    the period of construction, the latter being the relevant figures
    for the purposes of determining the Authority‘s obligations
    under the ADA.
    11
    In considering the parties‘ arguments under the ADA,
    it is important to bear in mind that the ADA‘s obligations are
    triggered at the time the construction is undertaken, not after
    it has been completed and litigation has commenced. See
    Roberts v. Royal Atl. Corp., 
    542 F.3d 363
    , 375 (2d Cir. 2008)
    (describing the ADA-compliance inquiry as ―backward-
    looking‖). Consequently, in assessing whether the Authority
    has violated the ADA, we evaluate the circumstances as of
    the time of construction. Questions of the feasibility of a
    proposed ADA-compliant modification, then, are directed not
    toward whether it would be feasible to execute the
    modification today, but rather whether it would have been
    feasible between 2002 and 2005. The District Court did not
    address this question, but, rather, chose from the options for
    reconstructing the station that were presented as ―feasible
    after the fact.‖ We cannot endorse this approach, and,
    accordingly, will remand for consideration of ―feasibility‖
    anew, as of the time of construction. The parties present us
    with numerous arguments as to why it would or would not
    have been feasible to make Grove Street Station ADA-
    accessible as part of the project at that time by installing an
    elevator to the platform level. These arguments were
    addressed to (and in some instances, ruled upon by) the
    District Court as part of the summary judgment motion
    proceedings. We will proceed to consider them.
    A
    The Authority‘s first preserved argument is that the
    ADA does not and cannot mandate a public transit authority
    to purchase subterranean property rights held by another
    party, which it would be required to do under Schemes 4 and
    5. It frames this argument under ADAAG § 4.1.6(1)(j),
    which states that ―if compliance with [the alteration
    12
    guideline] is technically infeasible, the alteration shall
    provide accessibility to the maximum extent feasible,‖ and
    defines ―technically infeasible‖ to mean, in relevant part, that
    ―other existing physical or site constraints prohibit
    modification or addition of elements, spaces, or features
    which are in full and strict compliance with the minimum
    requirements for new construction and which are necessary to
    provide accessibility.‖ ADAAG § 4.1.6(1)(j). We agree with
    the parties that the Authority bears the burden of proving
    technical infeasibility, as § 4.1.6(1)(j) acts as a kind of
    affirmative defense to otherwise applicable ADA compliance
    requirements. Cf. Roberts, 
    542 F.3d at
    370–71 (discussing
    Borkowski v. Valley Cent. Sch. Dist., 
    63 F.3d 131
    , 138 (2d
    Cir. 1995)) (holding in a Title III ADA case that the plaintiff
    need only ―mak[e] a facially plausible demonstration that the
    modification is an alteration‖ before the burden shifts to the
    defendant to show it is not an alteration); Turner, 
    440 F.3d at 614
     (observing that a disabled employee must make a prima
    facie showing that a proposed accommodation is possible
    before the burden shifts to the employer to prove that the
    accommodation is unreasonable or unduly burdensome).
    In Disabled in Action of Pennsylvania v. Southeastern
    Pennsylvania Transportation Authority (DIA v. SEPTA), 
    635 F.3d 87
     (3d Cir. 2011), we considered a similar issue
    regarding whether a district court can order ADA compliance
    notwithstanding the fact that the defendant does not presently
    possess property rights necessary to make the ordered
    modifications. In that case, DIA sued SEPTA and the City of
    Philadelphia over accessibility barriers at two subway access
    points, the 15th Street Courtyard and City Hall Courtyard. 
    Id. at 91
    . Early in the litigation, the city and DIA reached a
    settlement in which the city agreed to allow SEPTA to build
    13
    an elevator on its property at the 15th Street Courtyard and
    was dismissed from the suit as a result. 
    Id.
     We affirmed the
    district court‘s order that SEPTA make both courtyards
    accessible. 
    Id. at 97
    . Because compliance at the City Hall
    Courtyard also required use of the city‘s property, SEPTA
    argued that the Court could not order modification of that site
    without rejoining the city in the suit. 
    Id.
     Ultimately rejecting
    SEPTA‘s argument for the necessity of joinder pursuant to
    Federal Rule of Civil Procedure 19, we reasoned that because
    the city had already settled with DIA with respect to the other
    location, the city ―must [have] be[en] aware of DIA‘s current
    position,‖ and that the fact that the issue had not yet arisen in
    the lower court meant it did not pose a significant hurdle to
    relief. 
    Id. at 98
    . The majority of the panel concluded that
    ―SEPTA [would] have to work with the City in complying
    with [its] decision, something the City ha[d] already agreed to
    do with respect to the 15th Street Courtyard.‖ 
    Id.
    Of course here, unlike DIA, we have less of a clear
    indication that Jersey City is willing to cooperate with the
    Authority in making the station accessible. Though Plaintiffs
    have presented evidence that the mayor has indicated that the
    City could allow access to the property, it is the City Council
    that must vote on any such matter. Because we lack any
    similar indication from the City Council, we cannot assume
    that the Authority will be able to acquire the land rights it
    needs to implement Scheme 4 or 5. Accordingly, summary
    judgment need not be entered for the Authority, either.
    As we see it, the mere fact that the Authority would
    now have to acquire land from a third-party is not sufficient
    to render the proposed accommodations per se infeasible.
    Indeed, in considering feasibility, as we must, as of the time
    of the original construction, the Authority may have been able
    14
    to negotiate for the use or ownership of the relevant land in
    the manner it had to facilitate construction of the headhouse
    for the east entrance. In light of the mayor‘s letter to the
    Plaintiffs, this may still be the case. There is, however, an
    open factual question as to whether the relief ordered by the
    District Court would now be ineffective because the City
    Council might refuse to negotiate a subterranean easement or
    sale to the Authority. On this point, we remand for further
    development of the record.
    While it may be the case that joinder of the City
    becomes appropriate, as we see it, this issue can just as easily
    be resolved by introducing evidence of the City Council‘s
    intent to approve or deny the Authority‘s use or acquisition of
    the land required under Schemes 4 and 5. Until the Authority
    has demonstrated that the Council will not allow it to use the
    land, we cannot conclude that the proposed accommodations
    are infeasible within the meaning of the ADA.
    15
    B
    The next two issues focus on the consequences of
    implementing Schemes 4 and 5. Because the appropriate
    inquiry under the ADA is backward-looking, and because
    Schemes 4 and 5 have been presented as prospective
    possibilities, those schemes may not be identical to those
    asserted by Plaintiffs at trial on remand. However, we
    recognize that the proposed modifications that might have
    been feasible between 2002 and 2005 may closely resemble
    the concept behind Schemes 4 and 5—LULA elevators to the
    platform—and therefore we proceed to address the feasibility
    concerns raised by the parties with respect to those schemes.
    The parties dispute whether both of the schemes found
    feasible by the District Court require the removal of a load-
    bearing part of the Station or are otherwise technically
    infeasible. In addition to the definition set forth above,
    technical infeasibility exists where the modification ―has little
    likelihood of being accomplished because existing structural
    conditions would require removing or altering a load-bearing
    member which is an essential part of the structural frame.‖
    ADAAG § 4.1.6(1)(j). ―The structural frame shall be
    considered to be the columns and the girders, beams, trusses
    and spandrels having direct connections to the columns and
    all other members which are essential to the stability of the
    building as a whole.‖ ADAAG § 3.5; see Americans With
    Disabilities Act (ADA) Accessibility Guidelines for
    Buildings and Facilities, 
    56 Fed. Reg. 35,408
    , 35,428 (July
    26, 1991) (responding to a comment on the proposed
    guidelines by opining that the ―structural frame‖ definition
    does ―not include wood or metal studs or joists used in light-
    frame construction of interior walls and floors‖). As noted,
    technical infeasibility also encompasses situations where
    16
    ―other existing     physical   or   site   constraints   prohibit
    modification.‖
    The parties did not develop a good factual record on
    this issue below. The Authority argues that ―a roof structure‖
    would need to be removed in Scheme 4 and avers there were
    ―[f]actual conflicts‖ over the load-bearing-member issue in
    the District Court. Authority Br. 23–24. The Authority‘s
    reply brief provides further citations to record evidence that
    suggests, but stops short of explicitly stating, that in order to
    implement Schemes 4 or 5 the Station‘s ―structural conditions
    would require removing or altering a load-bearing member
    which is an essential part of the structural frame.‖ See
    Authority Reply Br. 16–18 (citing JA 415, 810, 1601–02).
    To offer just one example, the Authority‘s feasibility report
    on Plaintiffs‘ proposed Schemes 4 and 5 notes that those
    schemes ―[m]ay require structural modifications to ‗pressure
    slab‘ below stair at station entrance.‖ (JA 1601–02.) The
    Authority claims this ―pressure slab‖ is a load-bearing
    member falling within the technical infeasibility exception.
    By contrast, Plaintiffs assert there is no record
    evidence that the removal of a load-bearing member would be
    necessary under either scheme and they present an expert who
    opines that Schemes 4 and 5 are feasible. The Authority
    counters that Plaintiffs‘ expert does not understand the
    meaning of technical infeasibility.
    The lack of clarity in the record indicates there is a
    genuine dispute of material fact over whether a load-bearing
    member would need to be removed to make the east side
    accessible, whether Schemes 4 and 5 are otherwise
    technically infeasible, and whether they would have been
    infeasible had they been incorporated into the original
    17
    construction plans. Therefore, these issues must be submitted
    for trial.
    C
    Finally, the Authority contends that because Schemes
    4 and 5 do not pass scrutiny under a fire-safety standard
    (NFPA 130), their implementation would not be ―feasible‖
    under the ADA. NFPA 130, titled ―Standard for Fixed
    Guideway Transit and Passenger Rail Systems,‖ contains
    numerous recommendations for designing rail systems to
    minimize risks associated with fire. The Authority highlights
    two of these recommendations as relevant to Schemes 4 and
    5. First, as the District Court put it, ―a bidirectional corridor
    must be at least 44 inches wide to ensure safe ingress and
    egress.‖ hip II, 
    2011 WL 3957532
    , at *4. Second, according
    to the Authority, evacuation must be possible ―from the most
    remote point on the platform to a point of safety in six
    minutes or less.‖ Authority Br. 25. The District Court held
    that the corridor width in Schemes 4 and 5 exceeded the 44-
    inch minimum but the Court did not address the egress time
    restriction.
    The parties disagree about the deference owed to
    NFPA 130 under the ADA‘s framework.                  Plaintiffs
    characterize it as a safety standard that the Authority
    voluntarily implements, which cannot trump the mandatory
    ADA. The Authority suggests NFPA 130 implementation is
    necessary under federal transportation regulations that
    mandate compliance with fire-safety standards. For its part,
    the ADA does not address where, if at all, safety standards fit
    within its regulatory framework.
    18
    We believe the ―maximum extent feasible‖ test can
    account for such safety standards. ―[T]he phrase to the
    maximum extent feasible applies to the occasional case where
    the nature of an existing facility makes it impossible to
    comply fully with applicable accessibility standards through a
    planned alteration.‖ 
    49 C.F.R. § 37.43
    (b) (emphasis added);
    see 56 Fed. Reg. at 35,428 (―[E]xisting physical or site
    constraints prohibiting full and strict compliance . . . can
    result from legitimate legal requirements (e.g., a right of way
    agreement preventing construction of a ramp in front of a
    building).‖). The ability to comply with safety standards
    relates to ―the nature of an existing facility.‖ We leave it to
    the District Court to determine in the first instance the weight
    to be accorded to these safety standards. Nevertheless, we
    think it likely that where compliance with a safety standard is
    required by law, a modification that would not comply with
    that safety standard is not ―feasible.‖ Even where the
    standard is not legally mandated, if it is uniformly
    implemented by the agency under ADA scrutiny and widely
    used by other transit agencies, a district court should be
    reluctant to order the agency to deviate from it.
    We cannot discern the significance of NFPA 130 from
    the record before us, in large part because of the manner in
    which the issue was presented by the Authority to the District
    Court. The Authority did not raise NFPA 130 until after the
    Court heard argument on the motions for summary judgment
    (even if it did raise evacuation concerns more broadly), and
    the expert affidavits it submitted generically reference exit
    time but do not squarely address the six-minute limitation.
    Highly technical arguments require specificity in
    presentation, and while we cannot say that the Authority
    failed to raise this argument before the District Court, we
    19
    understand why the District Court believed the corridor-width
    issue to be the only one presented by NFPA 130. At the same
    time, Plaintiffs‘ expert was unfamiliar with NFPA 130 and
    offered no opinion on the Station‘s egress capacity. On this
    record, both the nature of the NFPA 130 requirement and
    whether Schemes 4 or 5 satisfy it are unclear and may be
    addressed by the District Court on remand.
    In sum, there are three triable issues of fact related to
    the feasibility of Schemes 4 and 5 under § 12147(a) or
    § 4.1.6(1)(j): the acquisition of property rights from Jersey
    City; the technical infeasibility of making Grove Street
    Station ADA-accessible, and, in particular, whether either
    requires removing or altering a load-bearing member; and the
    compliance (and necessity of compliance) of those Schemes
    with NFPA 130. Some of these issues may be resolved prior
    to submission of the case to the jury as described more fully
    above.
    IV
    Plaintiffs‘ cross-appeal concerns the District Court‘s
    dismissal of their state-law claims on the basis that the
    application of state law to an agency operating under an
    interstate compact is permissible only if provided for in the
    compact. Because the Authority‘s compact does not so
    provide, we will affirm.
    ―A bi-state entity, created by compact, is ‗not subject
    to the unilateral control of any one of the States that compose
    the federal system.‘‖ Int’l Union of Operating Eng’rs, Local
    542 v. Del. River Joint Toll Bridge Comm’n, 
    311 F.3d 273
    ,
    281 (3d Cir. 2002) (quoting Hess v. Port Auth. Trans-Hudson
    Corp., 
    513 U.S. 30
    , 42 (1994)). This is so because interstate
    20
    compacts entered into with congressional consent under the
    Compact Clause function as a ―surrender[] [of] a portion of
    their sovereignty‖ to an ―‗independently functioning part[] of
    a regional polity and of a national union.‘‖ Id. at 276
    (quoting Hess, 
    513 U.S. at 40
    ). ―Such a surrender of state
    sovereignty should be treated with great care, and the
    Supreme Court has stated that courts should not find a
    surrender unless it has been ‗expressed in terms too plain to
    be mistaken.‘‖ 
    Id.
     (quoting Jefferson Branch Bank v. Skelly,
    
    66 U.S. 436
    , 446 (1861)). ―Our role in interpreting the
    Compact is, therefore, to effectuate the clear intent of both
    sovereign states, not to rewrite their agreement or order relief
    inconsistent with its express terms.‖ 
    Id.
     (citing Texas v. New
    Mexico, 
    462 U.S. 554
    , 564–65 (1983)).
    In Delaware River, we considered a compact that did
    not contain the ―concurred in‖ language that is frequently
    found in interstate compacts to allow a state to modify a
    compact with legislation, provided its partner state passes
    similar legislation. 
    Id.
     Finding the absence of that language
    significant, we nonetheless reviewed various approaches
    taken by federal and state courts interpreting ―concurred in‖
    clauses in compacts. Some courts require an express
    statement of intent by both state legislatures to modify the
    compact, and other courts permit ―complementary or parallel‖
    actions of two state legislatures to imply the intent to modify
    the compact. 
    Id.
     at 276–79. Ultimately we applied the
    ―express intent standard‖ and found there was no evidence of
    intent by the states ―to amend the Compact or apply their
    collective bargaining laws to the‖ bi-state entity. Id. at 280.
    The compact between New York and New Jersey that
    created the Authority provides that ―[t]he port authority shall
    have such additional powers and duties as may hereafter be
    21
    delegated to or imposed upon it from time to time by the
    action of the legislature of either state concurred in by the
    legislature of the other.‖ 
    N.J. Stat. Ann. § 32:1-8
     (emphasis
    added) (codifying the compact); 
    N.Y. Unconsol. Law § 6408
    (same); accord 
    N.J. Stat. Ann. § 32:1-4
    ; 
    N.Y. Unconsol. Law § 6404
    . However, there is no dispute that the New Jersey
    laws relied upon by Plaintiffs do not purport to regulate the
    Authority, nor do Plaintiffs contend that there is an implied
    agreement based on parallel legislation to amend the compact.
    Instead, relying on New York case law, Plaintiffs urge
    the panel to distinguish between ―internal operations‖ and
    ―external conduct‖ of the Authority in applying these
    compact principles. See Agesen v. Catherwood, 
    260 N.E.2d 525
    , 526–27 (N.Y. 1970); see also Dezaio v. Port Auth. of
    N.Y. & N.J., 
    205 F.3d 62
    , 65 (2d Cir. 2000) (discussing
    Agesen but declining to apply New York state employment
    discrimination laws to the Authority, implicitly assuming that
    employment matters relate to the internal operation of the
    Authority). Specifically, Plaintiffs claim that while a state
    cannot regulate the Authority‘s internal operations on its own,
    it can regulate the external conduct of the agency. Plaintiffs
    define external conduct as actions relating to ―health and
    safety.‖ See Agesen, 260 N.E.2d at 526–27.
    There is no basis in Third Circuit precedent for the
    internal-external distinction, nor would such a distinction
    necessarily be well-founded.3 But we need not consider the
    3
    In Eastern Paralyzed Veterans Ass’n, Inc. v. City of
    Camden (EPVA), 
    545 A.2d 127
     (N.J. 1988), the New Jersey
    Supreme Court declined to adopt the internal-external
    distinction because ―[o]nly when the compact itself
    recognizes the jurisdiction of the compact states may it be
    22
    matter, for even if such a distinction were adopted, the
    decision of whether to comply with an anti-discrimination
    statute in constructing a facility is best described as an
    ―internal operation‖ because the decision does not relate to
    anything external to the Authority or to health or safety. The
    Authority‘s decisions on station construction do not threaten
    physical harm to New Jersey‘s citizens. Consequently, just as
    the Dezaio Court found that New York employment
    discrimination laws could not be applied to the Authority, so
    too is New Jersey barred from applying its civil rights and
    construction code statutes to the Authority. Cf. Am. Honda
    Fin. Corp. v. One 2008 Honda Pilot, 
    878 N.Y.S.2d 597
    , 600
    (N.Y. Sup. Ct. 2009) (suggesting that the Authority‘s claimed
    vehicular lien was an external matter not protected by its
    claim to autonomy but avoiding that holding because the
    Authority conceded the applicability of the state statute).
    subject to single-state jurisdiction.‖ Id. at 132. Plaintiffs
    claim that Delaware River is fundamentally inconsistent with
    this case, but the Delaware River Court, while rejecting
    EPVA‘s adoption of the implicit ―complementary or parallel
    test,‖ cited with approval EPVA‘s holding that an express
    statement attempting to regulate a bi-state entity was
    insufficient to modify a compact ―without ‗some showing of
    agreement by both states to the enforcement of the [state
    law].‘‖ 
    311 F.3d at
    280–81 (quoting EPVA, 545 A.2d at 133–
    34). Accordingly, even though we do not recognize implicit
    modifications of an interstate compact as the New Jersey
    Supreme Court might, both jurisdictions require evidence of
    mutual intent to alter a compact and regulate the bi-state
    agency, regardless of whether the action taken by the agency
    is ―external‖ or ―internal.‖
    23
    Plaintiffs also contend that ―the Compact contains no
    express surrender of state sovereignty regarding external
    relations, including, among other things, barrier-free
    construction codes and related civil rights statutes,‖ the
    subjects of Plaintiffs‘ state-law claims, meaning the Authority
    lacks the power to avoid the reach of these New Jersey laws.
    Plaintiffs Br. 34. This argument misapprehends the notion of
    sovereignty surrender discussed in Hess and Delaware River.
    While a court must be hesitant to find a surrender of
    sovereignty where it is ambiguous, here there is no question
    the states intended to create the Authority, and such surrender
    has already been recognized by numerous courts, including
    the United States Supreme Court in Hess. By expressly
    creating the bi-state entity, New York and New Jersey
    relinquished all control over the Authority unless otherwise
    stated in the compact.          Under Delaware River, that
    autonomous entity cannot be unilaterally regulated by New
    Jersey.
    V
    For the foregoing reasons, we will vacate the summary
    judgment of the District Court, we will affirm its dismissal of
    the state-law claims, and remand for further proceedings
    consistent with this opinion.
