    OPINION OF THE COURT
    _________________
    SCIRICA, Circuit Judge.
    At issue is whether the U.S. Army Corps of Engineers
    can deepen the main channel of the Delaware River by five
    feet, enabling river ports to be economically competitive and
    at the same time, comply with statutes that protect the
    environment. The roots of the project trace back decades. In
    6
    1992, Congress authorized the project and appropriated $195
    million. It continued to support the effort with regular
    appropriations for the next twenty years. 1 Commencement
    was delayed for several reasons, but in the fall of 2009, the
    Corps was ready to proceed. In October 2009, New Jersey
    and Delaware filed suits in the District Courts of New Jersey
    and Delaware to enjoin the Corps from dredging the deeper
    channel. They alleged violations of the National
    Environmental Policy Act (“NEPA”), the Clean Water Act
    1
    See, e.g., H.R. Rep. No. 111-278, at 50 (2009) (Conf. Rep.)
    (appropriating $4.8 million to the deepening project in the
    Energy and Water Development and Related Agencies
    Appropriations Act of 2010); H.R. Rep. No. 109-275, at 73
    (2005) (Conf. Rep.) (approving $2.25 million to the project in
    the Energy and Water Development Appropriations Act of
    2006). In 1999 and 2000, Congress also supported the project
    by extending credit to non-federal entities for costs related to
    design, construction, and disposal. See Water Resources
    Development Act of 2000, Pub. L. No. 106-541, § 306, 
    114 Stat. 2572
     (2000) (“The project for navigation, Delaware
    River Mainstem and Channel Deepening . . . is further
    modified to authorize the Secretary to credit toward the non-
    Federal share of the cost of the project . . . the costs incurred
    by the non-Federal interests in providing additional capacity
    at dredged material disposal areas . . .”); Water Resources
    Development Act of 1999, Pub. L. No. 106-53, § 308, 
    113 Stat. 269
     (1999) (same). Most recently, the U.S. House of
    Representatives approved $29.45 million for fiscal year 2013.
    See H.R. Rep. No. 112-462, at 29 (2010).
    7
    (“CWA”), and the Coastal Zone Management Act
    (“CZMA”). Each District Court granted summary judgment
    to the Corps, holding no environmental statutes would be
    breached. We will affirm.
    I.
    A.
    The federal government has maintained navigation in
    the Delaware River for over one hundred years. The initial
    project, “Philadelphia to the Sea,” was authorized by
    Congress in 1910 and ensures a navigation channel of 40-foot
    depth between Allegheny Avenue, Philadelphia, and a deep
    water point in the Delaware Bay, near Ship John Light. It
    requires the Corps to dredge 3.45 million cubic yards of
    material annually and to deposit the sediment at nearby
    locations, either owned or leased by the federal government.
    In 2009, the Corps used seven confined sites and one open-
    water site for disposal.
    The deepening project dates to 1954, when the Senate
    Committee on Public Works, by resolution, requested the
    Corps to study “the Delaware River between Philadelphia and
    the sea, for the purpose of identifying the need for any
    modification to the existing channel dimensions and
    anchorage areas.” In 1970, the House Committee on Public
    Works also instructed the Corps to analyze commerce along
    the Delaware River and to identify projects that would
    promote development of its ports. Pursuant to these
    directives, the Corps made extensive studies during the 1970s
    8
    and 1980s. In 1992, it published a Feasibility Report and
    Environmental Impact Statement (“EIS”), recommending a
    deepening of five feet along the “main stem” of the Delaware
    River, the 102-mile stretch between the mouth of the
    Delaware Bay and the Philadelphia and Camden harbors.
    The Environmental Impact Statement predicted the
    deepening project would yield substantial economic benefits
    in the form of reduced costs to shippers. The main stem of the
    river hosts a concentration of heavy industry, as well as the
    second largest complex of oil refineries and petrochemical
    plants in the nation. But, as the EIS observed, “current
    authorized channel dimensions . . . present a constraint to
    efficient vessel movement.” The report determined that
    deepening the main navigation channel by five feet would
    benefit oil tankers, dry bulk shippers, and other large vessels,
    because it would enable them to service Delaware River ports
    without needing to “lighter” (transfer a portion of their cargo
    in the lower Delaware Bay) or “light load” (travel at under-
    capacity). While the EIS identified potential adverse impacts
    to water quality, benthic organisms, and fishery resources, it
    concluded these would be minimal and were outweighed by
    the project’s benefits. Altogether, it forecast that construction
    and maintenance of a 5-foot deeper channel for five years
    would require the Corps to dredge 375 million cubic yards of
    material above the dredging associated with the Philadelphia
    to the Sea project.
    In June 1992, the Corps submitted the Environmental
    Impact Statement to Congress. That October, Congress
    passed the Water Resources Development Act, authorizing
    9
    the deepening project to go forward. See Water Resources
    Development Act of 1992, Pub. L. No. 102-580, § 101(6),
    
    106 Stat. 4797
     (“WRDA”). Congress estimated the project
    would cost a total of approximately $295 million, with $195
    million to be borne by the federal government. 
    Id.
     In
    December 1992, the Corps issued a Record of Decision
    stating the deepening project was “economically justified, in
    accordance with environmental statutes, and in the public
    interest.” Not only would “transportation cost savings . . .
    outweigh any adverse effects,” but the project was preferable
    to all other alternative plans, including a “no action”
    alternative.
    After issuing the Record of Decision, the Corps
    initiated the Preconstruction, Engineering and Design
    (“PED”) phase of the project. It consulted federal and state
    agencies and outside experts, and conducted new
    environmental analyses. In 1997, the Corps published a
    Supplemental Environmental Impact Statement (“SEIS”). Its
    goals were first, to “provide additional information and
    environmental analysis to address environmental concerns
    raised during review of the 1992 [EIS]”; and second, to
    evaluate modifications to the deepening project that had been
    made since the EIS was published. 2 Like the EIS, the SEIS
    2
    These modifications were primarily to the project’s disposal
    plan. In the EIS, the Corps assumed it would deposit the
    dredged sediment from the project at two existing and three
    new disposal sites. By 1997, the Corps planned to use four,
    rather than three, new disposal facilities. The Corps also
    embraced a proposal to store dredged material at four
    10
    recommended the project proceed. At the same time, it
    reduced its estimate of the amount of material to be dredged
    over 50 years – for initial project construction and future
    maintenance – from 375 to 321 million cubic yards. Like the
    EIS, the SEIS concluded the project would yield considerable
    economic benefits at a minimal environmental cost. On
    December 18, 1998, the Corps issued a second Record of
    Decision stating it had “reviewed and evaluated documents
    concerning the proposed action, including additional PED
    phase studies,” and it concluded “[t]he public interest will
    best be served by implementing the improvements identified
    and described in the Feasibility Report and the Supplemental
    Environmental Impact Statement.” The Record of Decision
    reiterated that “[a]ll practical means to avoid or minimize
    adverse environmental effects have been incorporated into the
    recommended plan.”
    For the next eleven years, progress on the deepening
    project stalled. One reason for the delay was that in the mid-
    2000s, the Delaware River Port Authority (“DRPA”)
    withdrew the support it had tendered in 1999, leaving the
    Corps without a local partner. 3 In June 2008, the Philadelphia
    “beneficial use” sites in Delaware and New Jersey – at Kelly
    Island, DE, for wetlands restoration; at Egg Point Island, NJ,
    also for wetlands restoration; and at Broadkill and Slaughter
    Beaches, DE, for beach nourishment. The sand for Broadkill
    Beach would first be stockpiled elsewhere.
    3
    The bi-state board of the DRPA came to stalemate at its
    meeting in December 2005, when the New Jersey
    commissioners on the board refused to endorse the deepening
    11
    River Port Authority (“PRPA”) came forward and signed a
    partnership agreement with the Corps. The agencies agreed to
    share costs: 75% for the Corps, 25% for PRPA.
    By late 2008, the Corps was ready to commence
    dredging the deeper channel. But over a decade had passed
    since the SEIS was published, and there were new
    developments. First, improved survey technology meant the
    deepening could be deployed more efficiently, reducing the
    amount of sediment. The total estimated dredging for the
    project over a 50-year period was reduced again, from 321 to
    232 million cubic yards. Accordingly, the updated disposal
    plan called for using only existing, federally-owned sites –
    the four new disposal sites included in the SEIS were no
    longer necessary. Second, the construction plan now called
    for dredged sand from the Delaware Bay to be deposited
    project and Pennsylvania Governor Ed Rendell, Chairman of
    the DRPA, refused to adopt the agency’s budget until the
    project was approved. See Geoff Mulvihill, Dredging Spat
    Deepens Between Two Neighbors, Associated Press, Dec. 31,
    2005. For the next 18 months, the meetings of the DRPA
    were suspended. In May 2007, the two states finally reached a
    deal: DRPA would return the $38.5 million set aside for the
    project to Pennsylvania and New Jersey, half-and-half; DRPA
    would hand jurisdiction over the project to the Philadelphia
    River Port Authority (“PRPA”); Pennsylvania would proceed
    in collaboration with PRPA; and New Jersey would use its
    share of the returned money for local improvement projects.

    Dredging Project, Associated Press, May 18, 2007.
    12
    directly onto Broadkill Beach, DE, rather than temporarily
    stockpiled offshore. Third, the reduction in the amount of
    predicted dredged material meant a wetlands restoration
    project at Egg Point Island, NJ, would be deferred. Finally,
    there were two environmental changes since 1997. An oil
    spill from the T/S Athos I in November 2004 had released
    265,000 gallons of oil into the Delaware River, temporarily
    increasing the toxicity of the river’s sediments. Also, recent
    surveys predicted an expansion in the number and distribution
    of shortnose sturgeon in the Delaware River, potentially
    increasing the risk that rock blasting in the Marcus Hook
    region could cause the species.
    The Corps released a public notice on December 17,
    2008, announcing it was undertaking a new “environmental
    review.” The notice stated:
    Notice is hereby given that the Philadelphia
    District, U.S. Army Corps of Engineers, is
    conducting an environmental review of all
    applicable, existing and new information
    generated subsequent to the Supplemental
    Environmental Impact Statement (SEIS) of
    1997 prepared for the Delaware River Main
    Stem and Channel Project . . . . At present, the
    Philadelphia District has found no factors
    precluding the Project from moving forward
    based on previous studies. A summary of
    project changes and environmental changes
    known to date is attached. The public and all
    agencies are invited to comment on the attached
    13
    changes, and to identify any applicable existing
    and new information generated subsequent to
    the 1997 SEIS by responding to this Public
    Notice. A copy of the SEIS of 1997 and other
    environmental studies performed since the
    completion of the SEIS, are among the
    information available on the District’s website.
    The environmental review referenced above
    will be used to update the environmental record,
    and to determine whether further environmental
    work and analyses are needed. 4
    On April 3, 2009, the Corps published an
    Environmental Assessment (“EA”). The report’s central
    conclusion was that no additional environmental impact
    statement was necessary. None of the developments since
    1997 – the elimination of the four new disposal sites, the plan
    for direct stockpiling at Broadkill Beach, the deferment of
    wetlands restoration at Egg Point Island, and the possible
    changes to the natural environment – had materially altered
    the project’s environmental risk profile. Thus, the EA closed
    with a signed declaration by the Commander of the Corps’
    Philadelphia District, stating:
    Based on the information contained in this EA .
    . . 1) none of the changes to the proposed
    project are “substantial”; and 2) there are no
    4
    The Corps provided the public four weeks for comments
    (initially, two weeks were provided but the Corps lengthened
    this in response to requests for more time).
    14
    new circumstances that can be considered
    “significant.” Therefore, I have determined that
    the threshold for preparation of a Supplemental
    Environmental Impact Statement (SEIS) . . . has
    not been met and that changes to the project or
    project conditions since the 1997 SEIS will not
    have a significant adverse effect on the human
    environment.
    Like the Environmental Impact Statement and Supplemental
    Environmental Impact Statement, the Environmental
    Assessment recommended the project proceed because its
    substantial economic benefits outweighed any possible
    adverse environmental effects. 5 On April 8, 2009, the Corps
    5
    The 2009 EA described the economic benefits of the
    deepening project as follows:
    The      NED       [National     Economic
    Development] benefits quantified include the
    reduced costs of transportation realized through
    operational efficiencies (reduced lightering and
    lightloading), and the use of larger more
    efficient vessels, both resulting from navigation
    improvements at the harbor. Reduced
    transportation costs result in reduced production
    and distribution costs and thereby increase the
    net value of the national output of goods and
    services.
    Benefits will result from the decrease in
    the cost per ton for shipping commodities into
    or out of the Delaware River Port System. The
    15
    transmitted the 1997 Supplemental Environmental Impact
    Statement and 2009 Environmental Assessment to the chairs
    of the Senate and House Subcommittees on Energy and Water
    Development in the Committees on Appropriations.
    When Congress first authorized the deepening project
    in 1992, the Corps initiated a comprehensive process of
    discussion, coordination, and collaboration with New Jersey
    and Delaware to obtain the state authorizations mandated by
    various environmental statutes. Two statutes are relevant to
    this appeal. First, the Coastal Zone Management Act
    45 foot channel depth will improve the
    economic efficiency of ships moving through
    the Delaware River ports. No induced tonnage
    (i.e., commodity shifts from other ports) will
    take place with the proposed project deepening.
    The largest vessels in the port fleet, crude oil
    tankers, currently lighter at Big Stone
    Anchorage in the naturally deep water of the
    lower Delaware Bay. These vessels will
    continue to carry the same tonnage from foreign
    origin ports but will be able to operate more
    efficiently in the Delaware River with a
    deepened channel from reduced lightering. This
    will also result in a reduction in barge traffic
    needed to move the lightered crude oil upriver
    to the refineries. Also, a deeper channel depth
    will allow current dry bulk and container
    vessels to carry more cargo as well as allow a
    fleet shift in the charter dry bulk market.
    16
    obligates the Corps to submit a “consistency determination”
    to any state whose “coastal zone” will be affected by one of
    its activities. 
    16 U.S.C. § 1456
    (c)(1)(A), (C).            The
    consistency determination describes how the Corps will
    deploy the project “in a manner which is consistent to the
    maximum extent practicable” with the state’s program for
    managing coastal areas. 
    Id.
     If the Corps receives a
    “concurrence,” it may proceed; if it does not, it can proceed
    over the state’s objection in limited circumstances. 
    15 C.F.R. §§ 930.41
    (a)-(d), 930.43(d). Second, the Clean Water Act
    requires the Corps to comply with all state laws “respecting
    the control and abatement of water pollution.” 
    33 U.S.C. § 1323
    (a). The Corps must obtain a state “water certification”
    when, on the basis of a federally-issued permit, it plans to
    discharge pollutants into a state’s navigable waters. 
    33 U.S.C. § 1341
    (a).
    To comply with the CZMA, the Corps submitted
    “consistency determinations” to the Delaware Department of
    Natural Resources and Environmental Control (“DNREC”)
    and the New Jersey Department of Environmental Protection
    (“NJDEP”) in 1996. Delaware identified several concerns, but
    provided a concurrence on May 1, 1997. New Jersey signed a
    Memorandum of Understanding with the Corps on August 29,
    1997, and on the same day, provided a concurrence.
    Accordingly, both CZMA clearances were in place in 1997.
    But each state retreated. New Jersey attempted to “revoke” its
    CZMA concurrence in September 2002, and requested
    supplemental filings from the Corps in 2008 and again in
    2009. Delaware issued an order requiring the Corps to submit
    a new consistency determination in 2009, contending
    17
    “substantial project modifications” had rendered its 1997
    concurrence outdated.
    The Corps did not provide supplemental consistency
    determinations to New Jersey or Delaware. Rather, on
    November 9, 2009, it issued a Memorandum of Record
    concluding that no additional coordination was necessary for
    the Corps to comply with the CZMA. The Corps referred to
    the April 2009 EA, which had found that no substantial
    changes to the project had been made and no significant new
    information about the project’s consequences had surfaced
    since the 1997 SEIS. Because concurrences from each state
    had been in place at that point in time, and because the
    project’s risk profile had not changed, it was not necessary to
    provide supplemental consistency determinations.
    On January 19, 2001, the Corps initiated coordination
    with Delaware to comply with the Clean Water Act; that is, it
    applied to the Delaware Department of Natural Resources and
    Environmental Control for a water quality “certification” as
    well as for Subaqueous Lands and Wetlands permits. See 7
    Del. Code chs. 60, 66 & 72. These efforts were unsuccessful.
    Significantly, Delaware took no action on the Corps’
    application for the next eight years. 6 On December 30, 2008,
    6
    DNREC did hold hearings on the Corps’ application in
    December 2001, soliciting public comments and hiring an
    independent consultant to serve as a Hearing Officer. In 2003,
    the Hearing Officer published a report recommending that
    Delaware deny the application. But DNREC did not act on
    the recommendation for the next five years.
    18
    it filed a comment in response to the public notice issued by
    the Corps on December 17, stating it would review any new
    information on the project “in the context of a new Delaware
    subaqueous lands and wetlands permit application.” The
    implication was that Delaware had denied, by inaction, the
    prior requests for Subaqueous Lands and Wetlands permits
    and was now requesting a new application. 7 On July 23,
    2009, eight and a half years after the Corps filed its
    application, Delaware made its denial of the 2001 application
    official by order of the Secretary of DNREC.
    The record does not indicate whether the Corps
    applied for a water quality certification from New Jersey to
    comply with the Clean Water Act. But neither party disputes
    that to date, the Corps has not obtained such a certification
    from New Jersey.
    Despite these roadblocks, the Corps issued a
    Memorandum of Record on April 30, 2009, invoking its
    authority to “maintain navigation” under Section 404(t) of the
    Clean Water Act. See 
    33 U.S.C. § 1344
    (t). This authority, the
    Corps contends, relieved it of any further obligation to obtain
    Subaqueous Lands and Wetlands permits from Delaware. The
    Corps drew additional authority from Section 404(r) of the
    CWA, which provides a special waiver for projects that are
    congressionally authorized. 
    Id.
     § 1344(r). It contends Section
    404(r) obviated the need to obtain water quality certifications
    from Delaware or New Jersey.
    7
    Delaware’s letter did not directly mention the issue of the
    water quality certification.
    19
    By late 2009, the Corps believed it had complied with
    all statutory mandates and could begin dredging the deeper
    channel. Under NEPA, it had published an Environmental
    Assessment in April 2009, concluding the project was in the
    public interest and that no additional environmental impact
    statements were necessary. Under the CZMA, it had
    submitted consistency determinations to New Jersey and
    Delaware in 1996, obtained concurrences within a year, and
    issued a Memorandum of Record announcing no additional
    CZMA coordination was necessary. Under the Clean Water
    Act, it had issued a separate Memorandum of Record in April
    2009, invoking Section 404(t) of the Act to overcome the
    need for the special Delaware permits, and believed it could
    otherwise rely on the Section 404(r) exemption to circumvent
    the water quality certifications. In October 2009, the Corps
    entered into a contract with PRPA which authorized it to
    initiate the project at “Reach C,” a 12-mile stretch spanning
    from the Delaware Memorial Bridge to the C&D Canal. The
    contract did not authorize the Corps to deepen any other
    portion of the river until December 2010.
    B.
    On October 30, 2009 and November 2, 2009, the
    Delaware Department of Natural Resources and
    Environmental Control and the New Jersey Department of
    Environmental Protection initiated actions in the District
    Courts of Delaware and New Jersey to prevent the Corps
    from commencing dredging of the deeper channel. In the
    Delaware action, DNREC sued under the Clean Water Act,
    Clean Air Act, Coastal Zone Management Act, and the
    20
    Delaware Code, requesting the court enjoin the Corps until it
    obtained the authorizations and concurrences from Delaware
    specified by those statutes. Delaware Riverkeeper Network
    (“Riverkeeper”) intervened as a plaintiff, and PRPA as a
    defendant. On January 29, 2010, the District Court granted in
    part and denied in part Delaware’s request. It preliminarily
    enjoined the project at Reaches A, B, D, and E, but allowed
    the Corps to commence at Reach C. 8 The parties filed and
    cross-filed motions for summary judgment, and on December
    7, 2010, the District Court dissolved its partial injunction and
    granted summary judgment to the Corps and PRPA. It held
    the Corps had properly invoked its authority to “maintain
    8
    The reasoning for the District Court’s ruling was as follows.
    At a hearing in December 2009, the Corps claimed
    construction at Reach C was slated to begin imminently, but
    subsequent phases would not commence until December
    2010. Meanwhile, despite its delay, DNREC had represented
    that it was prepared to complete its administrative review of
    the Corps’ application for the various state authorizations
    within a year. The District Court reasoned that while the
    Corps was likely to prevail on its claim that all federal
    statutes had been complied with, and so construction at
    Reach C should commence, there was no harm in enjoining
    the remainder of the project to enable DNREC to provide its
    decisions on the Corps’ application. Given that future phases
    of the project were not slated to begin for a year anyway, and
    that DNREC claimed it would complete its review within that
    time, the partial injunction would facilitate federal-state
    coordination while not compromising the Corps’ interests.
    21
    navigation” under Section 404(t) of the CWA, and this made
    all the difference. It held: “Having determined that the
    navigation exception . . . is applicable here . . . the Corps is
    exempt from compliance with the CWA, CZMA, and CAA,
    and judgment must be entered in its favor.”
    In the New Jersey action, NJDEP sought relief under
    NEPA, the CWA, the CZMA, the Clean Air Act, the Fish &
    Wildlife Coordination Act, the Water Resources
    Development Act, and the Magnuson-Stevens Fishery
    Conservation and Management Act. NJDEP asked the court
    to enjoin the Corps until it had “comprehensively sample[d]
    and analyze[d] the sediment within the areas to be dredged,”
    issued a new SEIS, obtained a water quality certificate from
    New Jersey, and completed its supplemental coordination
    under the CZMA. Riverkeeper again intervened as a plaintiff,
    and PRPA again intervened as a defendant. The parties filed
    and cross-filed motions for summary judgment and on
    January 13, 2011, the court granted summary judgment in
    favor of the Corps and PRPA. The court held the Corps had
    complied with NEPA when it issued the 2009 EA, complied
    with the CZMA when it declined to provide a supplemental
    consistency determination, and was relieved of its obligations
    under the CWA because Congress authorized the project in
    1992. Riverkeeper and New Jersey appealed both judgments
    under NEPA, the CZMA, and the CWA, and we consolidated
    their cases for review. Delaware did not file an appeal.
    As this litigation unfolded, the Corps made headway
    on the project. After receiving court approval in January
    2010, it commenced dredging at “Reach C” and completed
    22
    that segment in September 2010. In November 2011, the
    Corps began deepening the 4-mile stretch known as “Lower
    Reach B,” which extends from Oldsman Creek to the
    Delaware Memorial Bridge. That segment is now also
    complete. See Delaware River Main Channel Deepening

    We review grants of summary judgment de novo.
    Startzell v. City of Phila., 
    533 F.3d 183
    , 192 (3d Cir. 2008).
    Summary judgment is proper when the pleadings, the
    discovery, the disclosure materials on file, and any affidavits
    show that there is no “genuine dispute as to any material fact
    and the movant is entitled to judgment as a matter of law.”
    Fed. R. Civ. P. 56(a). Because appellants challenge the
    actions of a federal agency (the Corps) in its application of
    federal law (NEPA, the CWA, the CZMA, and corresponding
    regulations), our standard of review is informed by
    administrative law doctrines prescribing the degree of

    Appellants’ causes of action arise under federal law.
    Accordingly, the Delaware and New Jersey District Courts

    of the statutory challenges.
    III.
    New Jersey and Riverkeeper contend the Corps’
    decision to proceed with the project in 2009 ran afoul of
    NEPA procedurally and substantively. As for procedures,
    appellants contend the publication of the EA was arbitrary
    and capricious because the Corps failed to comply with the
    regulations governing the preparation of NEPA studies. As
    for substance, appellants contend the EA fell short of the
    “hard look” demanded by NEPA on whether an SEIS was
    necessary. As explained below, we find all NEPA claims
    unavailing.
    A.
    Congress enacted the National Environmental Policy
    Act of 1969, Pub. L. No. 91-190, 
    83 Stat. 852
     (codified at 
    42 U.S.C. § 4321
     et seq.), to further two goals: ensure federal
    agencies consider the environmental consequences of projects
    before committing resources; and facilitate agencies’
    communication with the public about their environmental
    analyses. Robertson v. Methow Valley Citizens Council, 
    490 U.S. 332
    , 350-52 (1989). NEPA is a procedural statute. Its
    goal is to “prohibi[t] uninformed – rather than unwise –
    agency action.” N.J. Dep’t of Envtl. Prot. v. U.S. Nuclear
    Regulatory Comm’n, 
    561 F.3d 132
    , 134 (3d Cir. 2009)
    (internal quotation marks and citation omitted). NEPA also
    24
    created the Council of Environmental Quality (“CEQ”) within
    the Executive Office of the President, granting it authority to
    issue regulations effectuating NEPA. CEQ regulations are
    “mandatory” for all federal agencies, carry the force of law,
    and are entitled to “substantial deference.” See Marsh v. Or.
    Natural Res. Council, 
    490 U.S. 360
    , 372 (1989); Andrus v.
    Sierra Club, 
    442 U.S. 347
    , 358 (1979). In addition to CEQ
    regulations, agencies are bound by whatever regulations they
    promulgate under NEPA. E.g., 
    33 C.F.R. § 230
     et seq. (U.S.
    Army Corps of Engineers’ regulations).
    NEPA requires federal agencies to prepare
    environmental impact statements before undertaking “major
    [f]ederal actions significantly affecting the quality of the
    human environment.” 
    42 U.S.C. § 4332
    (C). 10 To comply, an
    10
    In full, NEPA provides:
    [A]ll agencies of the Federal Government shall .
    . . include in every recommendation or report on
    proposals for legislation and other major
    Federal actions significantly affecting the
    quality of the human environment, a detailed
    statement by the responsible official on – (i) the
    environmental impact of the proposed action,
    (ii) any adverse environmental effects which
    cannot be avoided should the proposal be
    implemented, (iii) alternatives to the proposed
    action, (iv) the relationship between local short-
    term uses of man’s environment and the
    maintenance and enhancement of long-term
    productivity, and (v) any irreversible and
    25
    agency must first decide whether a contemplated project
    qualifies as a “major federal action significantly affecting the
    quality of the human environment.” CEQ regulations instruct
    the agency to consider both the “context” and “intensity” of
    the action to determine if its environmental effects will be
    “significant.” 
    40 C.F.R. § 1508.27
    (a)-(b). If the project
    qualifies, the agency should assess whether it is of a type that
    “[n]ormally requires an environmental impact assessment” or
    “[n]ormally does not require either an environmental impact
    statement or environmental assessment (categorical
    exclusion).” 
    Id.
     § 1501.4(a)(1)-(2). If the action normally
    requires an impact statement, the agency should prepare one.
    If it normally requires neither an impact statement nor an
    assessment, the agency can proceed with the project. In all
    remaining situations, the agency should “prepare an
    environmental assessment” for the action. Id. § 1501.4(b). An
    EA is a “concise public document” that “[b]riefly provide[s]
    sufficient evidence and analysis for determining whether to
    prepare an [EIS].” Id. § 1508.9(a). If the agency concludes on
    the basis of the EA that no environmental impact statement is
    needed, it must issue a Finding of No Significant Impact
    (“FONSI”). Id. § 1501.4(e).
    Agencies must update – or “supplement” – their
    environmental impact statements over time to ensure they are
    irretrievable commitments of resources which
    would be involved in the proposed action
    should it be implemented.
    
    42 U.S.C. § 4332
    (C).
    26
    current. Marsh, 
    490 U.S. at 370-74
    . CEQ regulations instruct
    agencies to “prepare supplements to either draft or final
    environmental impact statements” in two situations: (1) if
    “[t]he agency makes substantial changes in the proposed
    action that are relevant to environmental concerns,” or (2) if
    “[t]here are significant new circumstances or information
    relevant to environmental concerns and bearing on the
    proposed action or its impacts.” 
    40 C.F.R. § 1502.9
    (c)(1); see
    also 
    33 C.F.R. § 230.13
    (b) (requiring the Corps to
    supplement an EIS “whenever required as discussed in 40
    CFR 1502.09(c)”). The Supreme Court has elaborated that an
    agency must take a “hard look” in assessing whether either of
    the Section 1502.9(c) scenarios is present. Norton v. S. Utah
    Wilderness Alliance, 
    542 U.S. 55
    , 72-73 (2004).
    Understandably, neither NEPA nor CEQ regulations
    prescribes particular proceedings agencies should use in
    carrying out this “hard look.” In re Operation of Mo. River
    Sys. Litig., 
    516 F.3d 688
    , 695 (8th Cir. 2008). 11
    11
    For instance, there is no requirement that the agency use an
    EA to determine if a supplemental EIS is needed. In Marsh,
    the Supreme Court upheld a decision by the Corps not to
    issue a supplemental EIS when the agency had used a
    Supplemental Information Report (“SIR”) rather than an EA
    to assess new information. Marsh, 
    490 U.S. at 385
     (holding
    “the Corps acted within the dictates of NEPA in concluding
    that supplementation was unnecessary” when its SIR found
    “the new information was of exaggerated importance”).
    27
    B.
    Judicial review of agency conduct under NEPA is
    deferential. The sole question on review is whether the
    agency’s actions were arbitrary or capricious. See 
    5 U.S.C. § 706
    (2)(A). When an agency publishes an EA and concludes
    an EIS is not needed, courts set those determinations aside
    only if there is evidence they were arbitrary or capricious. See
    Dep’t of Transp. v. Pub. Citizen, 
    541 U.S. 752
    , 763 (2004)
    (“An agency’s decision not to prepare an EIS can be set aside
    only upon a showing that it was ‘arbitrary, capricious, an
    abuse of discretion, or otherwise not in accordance with
    law.’” (citing 
    5 U.S.C. § 706
    (2)(A)); Soc’y Hill Towers
    Owners’ Ass’n v. Rendell, 
    210 F.3d 168
    , 180 (3d Cir. 2000).
    Similarly, arbitrary and capricious review attaches to an
    agency decision not to supplement an EIS. Marsh, 
    490 U.S. at 375-76
     (“We conclude that review of the narrow question . . .
    whether the Corps’ determination that the FEISS need not be
    supplemented should be set aside is controlled by the
    ‘arbitrary and capricious’ standard of § 706(2)(A).”).
    If some years pass between an agency’s completion of
    an EIS and its commencement of a project, a supplemental
    EIS may be indicated. But in Marsh, the Court made clear
    that judicial review of agency conduct in such situations is
    “narrow,” as is generally the case with arbitrary and
    capricious review. Marsh, 
    490 U.S. at 378
    . An agency’s
    decision not to supplement an EIS “is a classic example of a
    factual dispute the resolution of which implicates substantial
    agency expertise.” 
    Id. at 376
    . Thus, the standard is still
    whether the action evidences arbitrary or capricious decision-
    28
    making. See Town of Winthrop v. Fed. Aviation Admin., 
    535 F.3d 1
    , 3 (1st Cir. 2008) (upholding the FAA’s decision in
    2007 not to supplement an EIS from 2002); Ark. Wildlife
    Fed’n v. U.S. Army Corps of Eng’rs, 
    431 F.3d 1096
    , 1103-04
    (8th Cir. 2005) (upholding the Corps’ decision in 2004, after
    conducting an EA, not to supplement an EIS from 1999);
    Price Road Neighborhood Ass’n, Inc. v. U.S. Dep’t of
    Transp., 
    113 F.3d 1505
     (9th Cir. 1997) (upholding the
    Federal Highway Administration’s determination that a
    project change did not require a new EA). 12
    12
    In South Trenton Residents Against 29 v. Federal Highway
    Administration, 
    176 F.3d 658
    , 663 (3d Cir. 1999), we
    “assume[d] . . . an agency’s determination not to revise an
    Environmental Impact Statement must be ‘reasonable under
    the circumstances.’” (internal citations and quotation marks
    omitted; alteration in original). But Marsh unquestionably
    held that review in such contexts is for arbitrary or capricious
    action. Marsh, 
    490 U.S. at 375-76
     (“The parties disagree . . .
    on the standard that should be applied by a court that is asked
    to review the agency’s decision. Petitioners argue that the
    reviewing court need only decide whether the agency
    decision was ‘arbitrary and capricious,’ whereas respondents
    argue that the reviewing court must make its own
    determination of reasonableness to ascertain whether the
    agency action complied with the law. In determining the
    proper standard of review, we look to § 10(e) of the
    Administrative Procedure Act (APA), 
    5 U.S.C. § 706
     . . . .
    We conclude that review of the narrow question before us
    whether the Corps’ determination that the FEISS need not be
    29
    C.
    In our review of the Corps’ conduct, we conclude that
    its publication of the 2009 EA was neither arbitrary nor
    capricious.
    1.
    The Corps complied with the procedural requirements
    prescribed by NEPA and its corresponding regulations
    because it engaged in a transparent and inclusive process,
    soliciting the views of federal and state agencies as well as of
    members of the public, and published an exhaustive, 179-
    page Environmental Assessment that reviewed the project’s
    risks, responded to concerns raised, and came to the
    reasonable conclusion the project should proceed.
    Neither CEQ nor Corps regulations detail the process
    an agency should follow when publishing an environmental
    assessment. See generally 
    40 C.F.R. § 1508.9
     (CEQ
    regulations defining EAs); 
    33 C.F.R. § 230.10
     (Corps
    regulations defining EAs). There are no notice requirements,
    pre-circulation requirements, or instructions about the public
    comments process. CEQ regulations only provide that
    agencies “shall involve . . . the public, to the extent
    practicable, in preparing [environmental] assessments[.]” 
    40 C.F.R. § 1501.4
    (b). This is different in the case of
    environmental impact statements, for which CEQ and Corps
    supplemented should be set aside is controlled by the
    ‘arbitrary and capricious’ standard of § 706(2)(A).”).
    30
    regulations are detailed. 13 See Greater Yellowstone Coal. v.
    Flowers, 
    359 F.3d 1257
    , 1279 (10th Cir. 2004) (“NEPA’s
    public involvement requirements are not as well defined
    when an agency prepares only an EA and not an EIS.”).
    The Corps’ procedures in preparing and publishing the
    2009 EA satisfied Section 1501.4(b)’s directive to “involve . .
    . the public to the extent practicable.” On December 17, 2008,
    the agency published a notice stating it was undertaking an
    “environmental review” in order “to update the environmental
    record, and to determine whether further environmental work
    and analyses are needed.” The Corps provided a summary of
    changes to the project that had been made since 1997 and
    links to the SEIS, EIS, and reports by other federal agencies.
    Collectively, the notice and appended materials
    communicated to the public that the Corps was undertaking a
    new environmental study of the deepening project and that its
    goal was to determine whether “further environmental work,”
    13
    CEQ regulations mandate that agencies “publish a notice of
    intent in the Federal Register” at the earliest “practicable”
    moment regarding the preparation of an environmental impact
    statement, 
    40 C.F.R. § 1501.7
    ; disseminate a copy of the draft
    or final EIS for public review before taking further action, 
    id.
    § 1506.10(b)(1), (2); “[r]equest comments [on the EIS] from
    the public, affirmatively soliciting comments from those
    persons or organizations who may be interested or affected,”
    id. § 1503.1(a)(4); and “respond by one or more of the means
    listed below” to the comments received, id. § 1503.4(a). See
    also 
    33 C.F.R. §§ 230.19
    , App. C ¶¶ 1-2 (regulations
    governing draft and final EIS reports).
    31
    such as a new SEIS, was needed. It directly provided the
    public with access to the information it would rely upon and
    solicited comments. The 30-day comment period was equal
    to the length of time mandated by CEQ regulations for
    comment periods for final EIS studies. 
    40 C.F.R. § 1506.10
    (b)(2).    The Corps was transparent, clear, and
    inclusive.
    After soliciting and reviewing the public comments,
    the Corps published a thorough, 179-page Environmental
    Assessment on April 3, 2009. The report addressed the
    substance of the most important issues raised in the comments
    – questions about sediment quality, water quality, air quality,
    biological resources, and the impacts of the Athos oil spill.
    Each environmental risk, the report concluded, was minimal
    and could be mitigated through appropriate implementation
    measures. The Corps also responded in great detail to a
    comment filed by the New Jersey Department of
    Environmental Protection on January 14, 2009, sending the
    agency a letter on April 24, 2009 that reiterated the findings
    of the EA and expounded on its conclusions.
    Despite the Corps’ comprehensive public engagement,
    appellants contend it acted arbitrarily and capriciously under
    NEPA. They argue the Corps provided inadequate public
    notice; erred in declining to publish a FONSI alongside the
    EA; erred in not circulating a draft of the EA for public
    review before publication; and did not meaningfully review
    the comments submitted. None of these claims has merit.
    32
    Regarding public notice, appellants contend the Corps
    did not specify the form of its forthcoming “review,” i.e., that
    it would be an Environmental Assessment, and that the
    comment period fell during a time of year when many people
    are on vacation. But as explained, neither NEPA nor its
    corresponding regulations impose a public notice requirement
    for EAs. See generally 
    40 C.F.R. § 1508.9
    ; 
    33 C.F.R. § 230.10
    . The CEQ regulations only direct that agencies
    “involve . . . the public, to the extent practicable.” 
    40 C.F.R. § 1501.4
    (b). The December 17, 2008 notice satisfied this
    mandate by describing a forthcoming “environmental review”
    that would be “used to update the environmental record, and
    to determine whether further environmental work and
    analyses are needed.” Furthermore, the Corps appended a
    wealth of materials to its notice to make evident the
    information it would rely upon and to solicit feedback on that
    information. Courts have upheld EAs preceded by public
    notices with the same or with considerably less detail than
    that here. E.g., Theodore Roosevelt Conservation P’ship v.
    Salazar, 
    616 F.3d 497
    , 519 (D.C. Cir. 2010) (involving a
    public notice that did not “suppl[y] any specific
    environmental information”); Bering Strait Citizens for
    Responsible Res. Dev. v. U.S. Army Corps of Eng’rs, 
    524 F.3d 938
    , 952-53 (9th Cir. 2008) (involving a notice that did

    398 F.3d 105

    mention a forthcoming EA).
    Second, appellants fault the Corps for publishing the
    EA without issuing a Finding of No Significant Impact. But
    33
    neither CEQ nor Corps regulations impose a FONSI
    requirement in this context – an agency deciding, on the basis
    of an EA, whether to issue a supplemental EIS. The
    regulations require FONSIs only when the agency employs an
    EA to decide whether to issue an initial EIS. See 
    40 C.F.R. § 1501.4
    (e) (instructing agencies to prepare “a finding of no
    significant impact (§ 1508.13) if the agency determines on the
    basis of an environmental assessment not to prepare a[n
    environmental impact] statement”); 
    33 C.F.R. § 230.11
     (“A
    FONSI shall be prepared for a proposed action, not
    categorically excluded, for which an EIS will not be
    prepared.”). Given that CEQ and Corps regulations authorize
    the use of EAs for a wide array of purposes, see 
    40 C.F.R. § 1501.3
    (b) (“Agencies may prepare an environmental
    assessment on any action at any time in order to assist agency
    planning and decisionmaking.”); 
    33 C.F.R. § 230.10
    (c), their
    silence on FONSIs for all but the initial EIS-determination is
    instructive. The Corps was not required to issue a FONSI, and
    its decision to refrain from doing so was not arbitrary or
    capricious. See In re Operation of Mo. River Sys. Litig., 
    516 F.3d at 695
     (“[T]he Corps prepared an EA, not to help it
    decide whether to prepare an EIS, but rather to determine
    whether the change in agency action required an SEIS. As
    this case illustrates, it is reasonable to expect that the Corps
    will sometimes determine that a FONSI is not appropriate
    because the action being taken has a significant impact on the
    environment, but an SEIS is not required because the impact
    was sufficiently analyzed in an earlier FEIS [Final
    34
    Environmental Impact Statement]. This approach is neither a
    misuse of the EA procedure nor a violation of NEPA.”). 14
    14
    We recognize that the Corps’ General Counsel, Earl
    Stockdale, came to a different conclusion on the necessity of
    a FONSI. In an internal memorandum prepared for the
    agency, he reasoned that “all EAs must result in either a
    FONSI or an EIS with no exception” and so “without
    preparing of a FONSI, the Corps will simply not have
    completed its required NEPA process.” This conclusion was
    incorrect. The sole regulatory provisions cited by Stockdale to
    support his analysis were 
    40 C.F.R. § 1501.4
    (e) and 
    33 C.F.R. § 230.11
    . These provisions do require FONSIs, but only for
    the initial EIS determination. See supra.
    Nonetheless, even if the FONSI requirement under
    Section 1501.4(e) attached, the Corps complied with it. The
    last page of the EA contained a signed declaration by
    Lieutenant Colonel Thomas Ticker, stating: “Based on the
    information contained in this EA and the referenced studies, I
    have concluded that . . . . the threshold for preparation of a
    Supplemental Environmental Impact Statement (SEIS) set
    forth at 40 CFR 1502.9(c) has not been met and that changes
    to the project or project conditions since the 1997 SEIS will
    not have a significant adverse effect on the human
    environment.” It was neither arbitrary nor capricious for the
    Corps to assume this signed declaration operated as a FONSI.
    The CEQ regulations define a FONSI as “a document by a
    Federal agency briefly presenting the reasons why an action .
    . . will not have a significant effect on the human environment
    35
    Third, appellants contend the Corps’ failure to
    circulate a draft of the EA before final publication was
    procedurally invalid. But neither CEQ nor Corps regulations
    impose a universal requirement to circulate draft EAs before
    publication. The CEQ regulations instruct that a document be
    disseminated for public review only when it is a draft or final
    EIS, 
    40 C.F.R. § 1506.10
    (b), or involves a “proposed action”
    that (i) would normally require an EIS which the agency has
    decided to forgo, or (ii) is “without precedent,” 
    id.
     §
    1501.4(e)(2)(i), (ii). The Corps’ regulations require that EAs
    be circulated before publication only when they concern
    “feasibility, continuing authority, or special planning reports
    and certain planning/engineering reports.” 
    33 C.F.R. § 230.11
    . The EA for the deepening project did not fall into any
    of these categories. 15 See Bering Strait Citizens, 524 F.3d at
    and for which an environmental impact statement therefore
    will not be prepared.” 
    40 C.F.R. § 1508.13
    .
    15
    The EA by definition was not a draft or final EIS, so was
    not covered by 
    40 C.F.R. § 1506.10
    (b). It also did not fall
    under either prong of 
    40 C.F.R. § 1501.4
    (e)(2) – it is not an
    action “which normally requires the preparation of an
    environmental impact statement” under § 1501.4(e)(2)(i),
    because Corps regulations provide an exclusive list of such
    actions at 
    33 C.F.R. § 230.6
     and the project does not qualify;
    and it is not an action “without precedent” under §
    1501.4(e)(2)(ii), because the Corps has maintained dredging
    operations in the Delaware River since 1910. Finally, the EA
    did not fall under 
    33 C.F.R. § 230.11
    . That section refers to
    reports produced by the Corps pursuant to specific regulatory
    36
    952 (“We hold today that the circulation of a draft EA is not
    required in every case. . . . Our conclusion is consistent with
    the views of other circuits, which uniformly have not insisted
    on the circulation of a draft EA.”); Fund for Animals, Inc. v.
    Rice, 
    85 F.3d 535
    , 549 (11th Cir. 1996) (holding there was
    “no legal requirement that an Environmental Assessment be
    circulated publicly and, in fact, they rarely are” (emphasis
    omitted)). Meanwhile, although some evidence in the record
    suggests the Corps often released EAs for public review
    before publication, this was a nonbinding internal practice
    from which the Corps had discretion to deviate. United States
    v. Caceres, 
    440 U.S. 741
    , 754 n.18 (1979) (“[A]gencies are
    not required, at the risk of invalidation of their action, to
    follow all of their rules, even those properly classified as
    ‘internal.’”). It exercised that discretion reasonably, given the
    long history of public involvement in reviewing and
    commenting on the deepening project, including the recent
    four-week comment period, and given the EA’s central
    conclusion that no factor or development altered the findings
    programs, none of which apply here. See 
    33 C.F.R. §§ 263.10
    , 263.15, 263.19 (“Continuing Authorities Program”);
    
    id.
     § 230 App. A (“feasibility studies”); see also Procedures
    for Implementing the National Environmental Policy Act
    (NEPA),

    , 3124 (Feb. 3. 1988) (explaining
    that 
    33 C.F.R. § 230.11
     requires a “30 day review of the EA”
    for the “types of actions” specified in the rule, none of which
    include dredging activities). Appellants appear to concede
    that none of the provisions mandating EA pre-circulation
    apply here. N.J. Br. at 44-46; Riverkeeper Br. at 79-81.

    of the earlier reports. E.g., Pogliani v. U.S. Army Corps of
    Eng’rs, 
    306 F.3d 1235
    , 1240 (2d Cir. 2002) (refusing to grant
    a preliminary injunction based on the Corps’ decision not to
    circulate a draft EA because the action was not one which
    “normally requires” an EIS nor “without precedent” under 
    40 C.F.R. § 1501.4
    (e)(2), and so did not have a pre-circulation
    requirement).
    Finally, appellants contend the Corps failed to
    meaningfully consider the public comments it received on its
    December 17, 2008 notice. But the 179-page Environmental
    Assessment comprehensively addressed the key issues raised
    in the comments. See supra. Furthermore, the record
    demonstrates over twenty years of engagement by the Corps
    with the public, state governments, and other federal
    agencies. The Corps’ activity in the 2008-2009 period was the
    final chapter of this engagement. On May 4, 1989, the Corps
    issued a notice of intent to file a Draft Environmental Impact
    Statement on the deepening project. It circulated a copy of
    that report for public comment on July 13, 1990, and released
    a final EIS in February 1992, incorporating the comments
    received. The Corps repeated this public engagement process
    for the SEIS in 1997. Between 1992 and 2008, it had a steady
    stream of communications with the EPA, New Jersey, and
    Delaware about the project’s compliance with the Clean
    Water Act and the Coastal Zone Management Act. It also
    engaged in rigorous coordination with the National Marine
    Fisheries Service (“NMFS”), conducting an Endangered
    Species Act consultation in 1996 and preparing a Biological
    Assessment for the agency in 2009. Given this twenty-plus
    year period of public, inter-state, and inter-agency
    38
    involvement, the assertion that the Corps failed to engage the
    public or respond to its views lacks merit. 16

    NEPA not only requires that agencies follow certain

    The record does not show the Corps’ decision to proceed
    with the project was “predetermined,” making the EA a sham

    NEPA reviews “must be taken objectively and in good faith,
    not as an exercise in form over substance, and not as a
    subterfuge designed to rationalize a decision already made.”
    Metcalf v. Daley, 
    214 F.3d 1135
    , 1142 (9th Cir. 2000). We
    will invalidate projects where the “agency has impermissibly
    committed itself to a course of action before embarking upon
    a NEPA analysis.” Forest Guardians v. U.S. Fish & Wildlife
    Serv., 
    611 F.3d 692
    , 716 (10th Cir. 2010). But there is no
    indication that the Corps “impermissibly committed itself” to
    the deepening project before completing the EA. It did not
    begin dredging or make an “irretrievable commitment of
    resources” while the environmental review was pending.

    . The one contract it entered into
    before the EA was finalized – the Project Partnership
    Agreement, which was signed with the Philadelphia Regional
    Port Authority on June 23, 2008 – expressly acknowledged
    that the Corps would “expeditiously construct the general
    navigation features . . . applying those procedures usually
    applied to Federal projects, pursuant to Federal laws,
    regulations, and policies.” In other words, construction was
    made contingent on a successful NEPA review.

    procedures when assembling environmental reports, but also
    that they take a “hard look” at the environmental costs of the
    proposed action as compared to the contemplated benefits.
    See Baltimore Gas & Elec. Co. v. Natural Res. Def. Council,
    Inc., 
    462 U.S. 87
    , 98 (1983) (“Congress, in enacting NEPA . .
    . . required [] that the agency take a ‘hard look’ at the
    environmental consequences before taking a major action.”);
    Vt. Yankee Nuclear Power Corp. v. Natural Res. Def.
    Council, Inc., 
    435 U.S. 519
    , 524 (1978). The Corps provided
    the necessary “hard look” at the project’s costs and benefits,
    and at whether an additional SEIS was needed for the project,
    in the 2009 EA. Riverkeeper and New Jersey advance three
    reasons for why the agency’s review was not sufficient, none
    of which is convincing.
    First, Riverkeeper argues the EA failed to adequately
    address the adverse impacts the project could cause on the
    shortnose sturgeon. The shortnose sturgeon was included in
    the federal Endangered Species list at least as far back as
    1996, meaning it bore that classification at the time the SEIS
    and EA were published. Some agencies and organizations had
    expressed concern during the comments period that the
    analysis of the shortnose sturgeon in the 1997 SEIS was no
    longer sufficient. New information about the species and its
    use of the Delaware River had become available, such that
    “the proposed deepening may affect shortnose sturgeon in a
    manner or to an extent not considered” previously.
    The EA contained no fewer than four separate sections
    on the shortnose sturgeon, including a comprehensive
    assessment of the species in an appended Essential Fish
    40
    Habitat Evaluation. The report acknowledged that recent
    surveys showed “a significant expansion in the number and
    distribution of shortnose sturgeon in the Delaware River
    appears likely,” but it also cited a 2005 study which found
    that “large aggregations of sturgeon do not exist in the
    blasting area.” Furthermore, it explained how blasting
    techniques could be honed to minimize harm to the species.
    The Corps drew on these analyses – as well as its findings in
    a Biological Assessment published for NMFS earlier that year
    – to conclude that adverse impacts to the shortnose sturgeon
    would be minimal. 17 The Corps’ conclusion was neither
    arbitrary nor capricious.
    Riverkeeper also contends the EA did not give a hard
    look to the dangers confronting the Atlantic sturgeon. NMFS
    17
    The Biological Assessment was prepared by the Corps in
    January 2009. In it, the Corps had concluded that any risks to
    shortnose sturgeon posed by the deepening project could be
    “minimize[d] and in some cases eliminate[d],” because “the
    majority of potential impacts would be related to the blasting
    activities . . . scheduled to take place in December and
    January of project Years 1 and 2.” NMFS endorsed the
    Corps’ findings in a Biological Opinion published in July
    2009. The Biological Opinion found: “[I]n its entirety, the
    proposed action is likely to result in direct physical effects . . .
    to no more than 57 shortnose sturgeon . . . . this number
    represents a very small percentage of the shortnose sturgeon
    population in the Delaware River . . . . [T]he proposed
    deepening project will not appreciably reduce the likelihood
    of survival . . . for this species . . . .”
    41
    designated the Atlantic sturgeon as a “candidate” for the
    Endangered Species list in 2006, and throughout the time at
    issue in this litigation, it retained that classification. 18
    “Candidate” species receive no statutory protection under the
    Endangered Species Act, but their vulnerability makes them
    appropriate for consideration in a NEPA review.
    The EA’s analysis of the Atlantic sturgeon was
    sufficient. The report contained two sections on “threatened
    and endangered species and other species of special concern,”
    each of which contained a sub-section on the Atlantic
    sturgeon. The sturgeon’s use of the Delaware River – from
    spawning, to hatching, to other migratory patterns – was
    analyzed in detail. Furthermore, every public comment about
    18
    On February 6, 2012, NMFS listed the New York Bight
    distinct population segment (“DPS”) of the Atlantic sturgeon
    as an Endangered Species. See Final Listing Rule for Gulf of
    Maine, New York Bight, and Chesapeake Bay Distinct
    Population Segments of the Atlantic Sturgeon in the
    Northeast Region, 
    77 Fed. Reg. 5880
    , 5909 (Feb. 6, 2012) (to
    be codified at 50 C.F.R. pt. 224). The New York Bight DPS
    includes sturgeon in the Delaware River. Id. at 5881, 5903,
    5912. Because NMFS’s endangerment listing post-dated the
    events in this litigation, it has no bearing on the quality of the
    EA. Nonetheless, we observe that it is unlikely the February
    2012 listing would change the EA’s conclusion that no
    additional SEIS was necessary for the project because the EA
    treated the Atlantic sturgeon as a species of “special
    concern,” given its “candidate” species listing at that time,
    and analyzed its vulnerability in several discussions.
    42
    the vulnerability of the species that Riverkeeper cites in its
    Brief was also addressed in the EA. See Riverkeeper Br. at 85
    (citing comments by NMFS, Prof. Dewayne Fox, and the
    Delaware River Basin Fish and Wildlife Management
    Cooperative). The Delaware River Basin Fish and Wildlife
    Management Cooperative filed a comment recommending the
    Corps “establish dredging and blasting windows that would
    result in the lowest probable impact to existing sturgeon
    populations of both Atlantic as well as shortnose.” The EA
    adopted this proposal: “All of these windows will be met
    during construction of the deepening project,” save for one,
    which was infeasible. Professor Dewayne Fox of Delaware
    State University advised the Corps to take into account “the
    large body of work . . . done primarily by both DSU and the
    Delaware Department of Fisheries and Wildlife” about the
    Atlantic sturgeon. The EA devoted three pages to the studies
    of Professor Fox. NMFS informed the Corps it would
    “recommend protective measures” for the Atlantic sturgeon.
    The Corps committed to using “environmental windows” and
    “[c]onstruction techniques” to “reduce the impacts of rock
    blasting on fish,” and to working collaboratively with NMFS
    during the project design phase. 19
    19
    Appellants draw our attention to a recent Ninth Circuit
    decision in which the court invalidated a supplemental EIS
    for, in part, failing to “provide baseline data for many of the
    species, and instead plan[ning] to conduct surveys and studies
    as part of its post-approval mitigation measures[.]” N. Plains
    Res. Council, Inc. v. Surface Transp. Bd., 
    668 F.3d 1067
    ,
    1083 (9th Cir. 2011) (“Northern Plains”). Northern Plains is
    43
    Finally, New Jersey contends the EA’s analysis of
    potential water contamination was deficient. In two ways,
    New Jersey argues, the EA lacked the necessary data for a
    robust analysis. First, it did not include up-to-date sediment
    samples from “bend-widening areas” in the Delaware River,
    which are necessary to obtain “‘a worst case picture of
    contaminant concentrations that would potentially be in the
    dredged material.’” N.J. Reply Br. 19 (citing the SEIS).
    Second, New Jersey claims the EA omitted a “modified
    elutriate analysis,” which was important for predicting how
    dredged material, stored upstream, would impact surface
    water quality.
    Neither purported data shortcoming rises to the level
    of arbitrary or capricious action. The EA relied on a broad
    array of studies, surveys, and sediment samples to ground its
    analysis of the potential water contamination from the project.
    First, it relied on sediment samples evaluated in the SEIS,
    which New Jersey concedes included samples from bend-
    widening areas. These had shown no bioaccumulation of any
    significance in the river’s sediment, and no potential for the
    inapposite. The report in Northern Plains was deficient
    because it sought to obtain baseline data, necessary for the
    agency’s approval of a project, from mitigation measures to
    be instituted after the project was underway. 
    Id. at 1084
    . The
    agency put the cart before the horse. Here, the EA contained
    considerable baseline data on the Atlantic sturgeon, such as
    studies from 2003 through 2007, and relied on mitigation
    measures only to conclude the project could be deployed in a
    way that would avoid causing significant harm to the species.
    44
    deepening to increase the water’s toxicity. Second, the EA
    “incorporated . . . by reference” the modified elutriate
    analysis from the SEIS, which similarly concluded that
    “dredging and dredged material disposal operations would not
    significantly impact water quality within the Delaware
    River.” Third, the EA relied on two studies by the Corps in
    2003 and 2005, analyzing “[a] total of 45 sediment cores”
    from the main channel and concluding there was negligible
    contamination. Finally, the EA relied on 162 sediment
    samples collected by the National Oceanic and Atmospheric
    Administration from intertidal and subtidal areas for a 2007
    report. These samples showed the 2004 oil spill had left no
    lingering effects and “baseline conditions (i.e., no spill-
    associated service losses) [we]re reached in 14 months.”
    Altogether, this material provided the Corps a sufficient basis
    from which to analyze how the project would impact water
    contamination in the Delaware River and from which to draw
    well-reasoned, non-arbitrary conclusions. 20
    20
    New Jersey claims it flagged the need for updated sediment
    samples from bend-widening areas and for a modified
    elutriate analyses in its public comment from January 14,
    2009. Accordingly, it claims the EA’s failure to include such
    data was indefensible, as demonstrated in the recent case of
    Sierra Club v. Van Antwerp, 
    661 F.3d 1147
    , 1157 (D.C. Cir.
    2011) (holding it would have been arbitrary and capricious
    for the Corps to issue a FONSI that failed to address a
    comment raised by an expert about a threatened species, and
    remanding for factfinding on that issue). But New Jersey’s
    January 14 comment had not mentioned modified elutriate
    45
    IV.
    Riverkeeper contends the Corps’ decision to proceed
    with the deepening project violated the Clean Water Act.
    First, Riverkeeper argues it violated Section 401(a), which
    requires recipients of federal permits who release “discharge”
    in navigable waters to obtain “a certification from the State in
    which the discharge originates or will originate.” 
    33 U.S.C. § 1341
    (a)(1). The Corps never secured water certifications from
    New Jersey or from Delaware for the project. Second,
    Riverkeeper contends the Corps’ actions ran afoul of Sections
    313 and 404(t), which obligate federal agencies to comply
    with state environmental regulations when engaging in
    dredging operations. 
    33 U.S.C. § 1323
    (a); 
    id.
     § 1344(t). After
    eight years of delay, Delaware denied the Corps two permits
    required by state law for users of subaqueous lands and
    wetlands in July 2009; nonetheless, the Corps decided to
    proceed. In response to Riverkeeper’s challenges, the Corps
    contends it is entitled to two statutory exemptions codified at
    Sections 404(r) and 404(t) of the CWA. For the reasons
    stated, we hold that both exemptions attach.
    analysis. And while it called for updated sediment samples
    from bend-widening areas, the EA relied upon reports
    assembled in 2003, 2005 and 2007, all of which included
    updated sediment samples. See supra. The Corps’ judgment
    that these samples were sufficient to offer the agency a
    complete picture of water contamination merits deference.
    46
    A.
    The Clean Water Act (“CWA”) was enacted in 1972 to
    “restore and maintain the chemical, physical, and biological
    integrity of the Nation’s waters.” Federal Water Pollution
    Control Act, Pub. L. No. 92-500, § 101(a), 
    86 Stat. 816
    (1972). Under its principal provision, “the discharge of any
    pollutant by any person shall be unlawful.” 
    33 U.S.C. § 1311
    (a). The “discharge of a pollutant” is defined as “any
    addition of any pollutant to navigable waters from any point
    source,” see 
    id.
     § 1362(12); “navigable waters” are defined as
    “waters of the United States, including the territorial seas,” id.
    § 1362(7); and “pollutant” is defined as including “dredged
    spoil, . . . rock, sand, [and] cellar dirt,” id. § 1362(6). The
    Delaware River readily qualifies as a “navigable water”
    because it is a “relatively permanent . . . continuously flowing
    bod[y] of water forming geographic features that are
    described in ordinary parlance as . . . rivers,” Rapanos v.
    United States, 
    547 U.S. 715
    , 739 (2006) (internal quotation
    marks and citation omitted); and dredging qualifies as the
    “discharge of a pollutant” because it results in the “addition”
    of “dredged spoil” to a navigable water. Under Section
    404(a), however, the U.S. Army Corps of Engineers may
    “issue permits . . . for the discharge of dredged or fill material
    into the navigable waters at specified disposal sites.” See
    CWA § 404(a) (codified at 
    33 U.S.C. § 1344
    (a)). The Corps
    “exercises the discretion of an enlightened despot” in issuing
    discharge permits, Rapanos, 
    547 U.S. at 721
    , and considers a
    broad range of factors set forth in its regulations, see 
    33 C.F.R. § 320.4
    . But there is one statutory obligation
    incumbent upon the Corps. Before issuing a permit, it must
    47
    apply “guidelines developed by the Administrator [of the
    EPA], in conjunction with the Secretary [of the Army],”
    which prescribe a rigorous review of a project’s
    environmental costs. CWA § 404(b)(1) (codified at 
    33 U.S.C. § 1344
    (b)); 
    40 C.F.R. § 230.10
     et seq. 21
    The Clean Water Act requires federal agencies and
    holders of federally-issued discharge permits to comply with
    state and local environmental laws in two pertinent ways.
    First, under Section 401(a), the Act requires holders of U.S.
    Army Corps permits, issued pursuant to Section 404, to
    obtain “certifications” from the states in which the discharge
    into navigable waters will occur. CWA § 401(a) (codified at
    
    33 U.S.C. § 1341
    (a)(1)) (“Any applicant for a Federal license
    or permit to conduct any activity . . . which may result in any
    discharge into the navigable waters, shall provide the
    licensing or permitting agency a certification from the State in
    which the discharge originates or will originate . . . that any
    such discharge will comply with the applicable provisions of
    [other sections of this title].”). The state certification “shall
    become a condition of any Federal license or permit subject
    to the provisions of this section.” 
    33 U.S.C. § 1341
    (d).
    Second, under Sections 313 and 404(t), the Act requires
    federal departments and instrumentalities to comply with state
    21
    When the Corps seeks to undertake a project that will
    release discharge, it does not go through the formality of
    issuing a permit to itself. Instead, it follows “all applicable
    substantive legal requirements” under Section 404, including
    an application of the Section 404(b)(1) guidelines. 
    33 C.F.R. § 336.1
    (a).
    48
    environmental laws when they engage in activities that emit
    pollutants into navigable waters. CWA § 313 (codified at 
    33 U.S.C. § 1323
    (a)) (“Each department, agency, or
    instrumentality of the executive, legislative, and judicial
    branches of the Federal Government . . . shall be subject to,
    and comply with, all Federal, State, interstate, and local
    requirements . . . respecting the control and abatement of
    water pollution . . . .”); CWA § 404(t) (codified at 
    33 U.S.C. § 1344
    (t)) (“[Every federal] agency shall comply with such
    State or interstate requirements both substantive and
    procedural to control the discharge of dredged or fill material
    to the same extent that any person is subject to such
    requirements.”).
    But the Act also provides exceptions to the provisions
    cited, enacted as part of the Clean Water Act of 1977, Pub. L.
    No. 97-217, 
    91 Stat. 1566
    . As to the water certification
    requirement under Section 401(a), Section 404(r) creates an
    exemption for projects “specifically authorized” by Congress.
    See CWA § 404(r) (codified at 
    33 U.S.C. §1344
    (r)) (“The
    discharge of dredged or fill material as part of the
    construction of a Federal project specifically authorized by
    Congress . . . is not prohibited by or otherwise subject to
    regulation under this section . . . .”). As to the mandates to
    follow states’ environmental laws, codified at Sections 313
    and 404(t), the final sentence of Section 404(t) provides a
    partial waiver. See CWA § 404(t) (codified at 33. U.S.C. §
    1344(t)) (“This section shall not be construed as affecting or
    impairing the authority of the Secretary to maintain
    navigation.”); see also S. Rep. No. 95-370, at 68-69 (1977)
    (“[C]orps dredging activities are not exempt from State
    49
    pollution abatement requirements. . . . [But this] is neither
    intended nor expected to result in compromising the ability of
    the corps to maintain navigation.”). Before Section 404(t) was
    added in 1977, the CWA had included a provision, still in
    force, that similarly preserved the Corps’ authority to
    “maintain navigation.” See CWA § 511(a)(2) (codified at 
    33 U.S.C. § 1371
    (a)(2)) (“This chapter shall not be construed as .
    . . affecting or impairing the authority of the Secretary of the
    Army (A) to maintain navigation or (B) under the Act of
    March 3, 1899[.]”).
    B.
    The Corps asserts it was relieved of the need to obtain
    water certifications from New Jersey and Delaware under
    Section 401(a) of the CWA by virtue of the “congressionally
    authorized” exception under Section 404(r). Riverkeeper
    disagrees, but we find the Corps’ argument convincing. 22
    22
    Riverkeeper argued the Corps violated CWA § 401(a), and
    that CWA § 404(r) did not apply, at summary judgment in
    both district courts. New Jersey raises this claim for the first
    time on appeal. See N.J. Br. at 60. A party’s failure to raise an
    issue in district court typically results in forfeiture of the
    claim. Brenner v. Local 514, United Bhd. of Carpenters &
    Joiners of Am., 
    927 F.2d 1283
    , 1298 (3d Cir. 1991) (holding
    “[i]t is well established that failure to raise an issue in the
    district court constitutes a waiver of the argument” unless
    certain “extraordinary circumstances” exist). We need not
    resolve whether to consider the Section 401(a) claim as to
    50
    As an initial matter, we agree with the Corps that “all
    of the elements of section 404(r) have been satisfied” for the
    deepening project. Section 404(r) provides:
    The discharge of dredged or fill material as part
    of the construction of a Federal project
    specifically authorized by Congress . . . is not
    prohibited by or otherwise subject to regulation
    under this section . . . if information on the
    effects    of    such    discharge,     including
    consideration of the guidelines developed under
    subsection (b)(1) of this section, is included in
    an environmental impact statement for such
    project pursuant to the National Environmental
    Policy Act of 1969 [
    42 U.S.C.A. § 4321
     et seq.]
    and such environmental impact statement has
    been submitted to Congress before the actual
    discharge of dredged or fill material in
    connection with the construction of such project
    and prior to either authorization of such project
    or an appropriation of funds for such
    construction.
    
    33 U.S.C. § 1344
    (r). Accordingly, to trigger Section 404(r),
    there must be a federal project specifically authorized by
    Congress. The deepening project unquestionably qualifies, as
    Congress clearly authorized it in the Water Resources
    Development Act of 1992, Pub. L. No. 102-580, § 101(6),
    New Jersey because we find it to lack merit, when evaluated
    as to Riverkeeper.
    51
    
    106 Stat. 4797
    , 4802 (“[T]he following projects for water
    resources development and conservation and other purposes
    are authorized to be carried out by the Secretary . . . . The
    project for navigation, Delaware River Mainstem and
    Channel Deepening, Delaware, New Jersey, and
    Pennsylvania: Report of the Chief of Engineers, dated June
    29, 1992, at a total cost of $294,931,000, with an estimated
    Federal cost of $195,767,000 . . . .”). Section 404(r) also
    requires that “information on the effects of [the project],
    including consideration of the guidelines developed under
    subsection (b)(1)” be “included in an environmental impact
    statement . . . submitted to Congress before the actual
    discharge of dredged or fill material . . . and prior to either
    authorization of such project or an appropriation of funds for
    such construction.” 
    33 U.S.C. § 1344
    (r). This prerequisite
    was met. The Corps transmitted an EIS to Congress in June
    1992 that had been prepared pursuant to NEPA and that
    included, as Section 404(r) directs, a “consideration of the
    guidelines developed under subsection (b)(1).” The
    transmission occurred five months before Congress
    authorized the project or appropriated funds, see WRDA, 106
    Stat. at 4797 (showing a date passage of October 31, 1992),
    and years before any “actual discharge” occurred.
    Nonetheless, Riverkeeper contends Section 404(r)
    does not apply for two reasons. The first is that the 1992 EIS
    was incomplete because it lacked a Record of Decision. The
    Record of Decision was issued in December 1992, two
    months after the WRDA was enacted. But this is of no
    moment. Section 404(r) mandates that “[an] environmental
    impact statement . . . [prepared] pursuant to the National
    52
    Environmental Policy Act” be provided to Congress and that
    it “includ[e] consideration of the guidelines developed under
    subsection (b)(1)”; it never mentions a Record of Decision.
    The absence of a Record of Decision in the congressional
    submission violates no statutory command. Furthermore, the
    purpose of Section 404(r) is for Congress to receive sufficient
    information in order to make an informed judgment about
    whether to authorize a federal project. In cases like this,
    where an EIS is produced after a full-fledged notice and
    comment process, bears the title of “final” impact study, and
    is transmitted to Congress with an explicit request for a
    Section 404(r) exemption, that purpose has been achieved. 23
    23
    The recent case of Board of Mississippi Levee
    Commissioners v. EPA, 
    674 F.3d 409
     (5th Cir. 2012) is
    consistent with our holding. In that case, the Fifth Circuit held
    that Section 404(r) of the CWA had not been triggered when
    a report provided to Congress lacked, among other things, a
    Record of Decision. The absence of a Record of Decision was
    one factor among several that persuaded the court to find the
    report had not been an agency’s “final EIS.” In addition to the
    lack of a Record of Decision, the agency’s transmittal letter to
    Congress plainly stated the report was not final. 
    Id.
     at 414-
    15. Four months after the report was transmitted to Congress,
    the Chief of Engineers prepared a “final report” for the same
    project. 
    Id. at 415
    . And because the original report sent to
    Congress was not in the record, the court could not determine
    whether it was labeled a “final” EIS. The Fifth Circuit held
    these factors collectively proved the document provided to
    Congress had not been a “final EIS” and accordingly, Section
    53
    Second, Riverkeeper contends the SEIS invalidated
    whatever exemption had been attained by virtue of the EIS.
    Riverkeeper claims the SEIS stands as proof that by 1997, the
    deepening project had changed to such an extent and new
    information had become available to such a degree, that
    Congress’s 1992 statutory authorization was no longer
    binding. But nothing in the text of Section 404(r) suggests
    that once the exemption attached, it lapses. The plain
    language of the statute states that when Congress
    “specifically authorizes” a federal project, following its
    consideration of an EIS, the exemption is triggered. 
    33 U.S.C. § 1344
    (r). There is no requirement that the agency submit
    supplemental NEPA reports so Congress can reauthorize the
    venture. Furthermore, the SEIS’s central findings were that
    despite the developments between 1992 and 1997 – e.g.,
    modifications to the project, new scientific information that
    became available – the conclusions in the EIS still applied.
    The SEIS stated: “[R]efinements to the authorized plan that
    were recommended in the 1992 Interim Feasibility Report . . .
    . did not alter the environmental impacts that were presented
    in the Final Environmental Impact Statement” and the project
    still “compl[ied] with the 404(b)(1) guidelines.” There was
    no need to solicit reauthorization from Congress because the
    project had not changed in a material way.
    404(r) had not been triggered. Id. at 419. Here, the EIS
    transmitted to Congress in June 1992 was entitled “Final
    Interim Feasibility Report,” was produced after a full notice
    and comment process, and was sent with a transmittal letter
    requesting the Section 404(r) exemption.
    54
    In sum, Section 404(r) of the CWA was triggered in
    1992 and did not lapse by virtue of the Corps’ subsequent
    NEPA analyses. The Corps was relieved of the federal
    permitting requirement under Section 404, see 
    33 C.F.R. § 323.4
    (d) (explaining that “[f]ederal projects which qualify
    under the criteria in section 404(r) of the CWA are exempt
    from section 404 permit requirements”), as well as from the
    water certification requirement under Section 401(a), see 
    33 U.S.C. § 1341
    (a)(1) (stating the certification mandate attaches
    to “applicant[s] for a Federal license or permit to conduct any
    activity”). The fact that the Corps attempted to work
    collaboratively with New Jersey and Delaware for several
    years does not undermine its lawful reliance on the Section
    404(r) exemption.
    C.
    The Corps contends it was relieved of Sections 313
    and 404(t) of the Clean Water Act, which required it to obtain
    special Delaware permits, because it was entitled to a
    statutory exemption codified at Section 404(t). We afford
    Skidmore deference to the Corps’ invocation of Section 404(t)
    and find its interpretation of the statute reasonable. We also
    find the Corps was neither arbitrary nor capricious in deciding
    to invoke Section 404(t).
    The Delaware Subaqueous Lands Act “empower[s] the
    Secretary to deal with or dispose of interest in public
    subaqueous lands.” 7 
    Del. Code Ann. tit. 7, § 7201
    . Under
    that authority, DNREC promulgated regulations instructing
    that “[n]o . . . project which may potentially impact the public
    55
    interest in the use of tidal or navigable waters [or] contribute
    to water pollution . . . shall be undertaken on public or private
    subaqueous lands unless approval has been obtained from the
    Department.” 7 Del. Admin. Code § 7504-2.7. The Delaware
    Wetlands Act provides that “[a]ny activity on the wetlands
    requires a permit from [DNREC].” 7 
    Del. Code Ann. tit. 7, § 6604
    (a). The word “activity” is defined to include dredging
    operations. 
    Id.
     § 6603. Both permit requirements extend to
    the deepening project because it calls for the disposal of
    dredged material at three subaqueous land-sites in Delaware
    and for a wetlands restoration project in Delaware. 24
    24
    The record reveals some confusion as to whether the
    wetlands permit was necessary and as to whether the Corps’
    2001 application was made pursuant to the Wetlands Act or
    solely the Subaqueous Lands Act. Neither party has raised
    this issue on appeal. We assume both were required and that
    the Corps applied for both.
    It is also worth noting the permits mandated by the
    Subaqueous Lands and Wetlands Acts were not affected by
    the exemption codified at Section 404(r). Section 404(r)
    relieves projects “specially authorized” by Congress from the
    permitting requirements in Section 404. One of those
    requirements, codified at Section 401(a), is to obtain a state
    water certification. 
    33 U.S.C. § 1341
    (a)(1). But for a water
    certification to fall under Section 401(a), it must be issued by
    a state body operating a “permit program” that regulates
    “discharges into navigable waters” and that has been
    approved by the EPA. 
    33 U.S.C. § 1342
    (b). The Delaware
    Subaqueous Lands and Wetlands Acts create permit programs
    56
    The Corps applied for subaqueous lands and wetlands
    permits in 2001. For eight years, Delaware stalled on its
    application. In light of Sections 313 and 404(t) of the CWA,
    which obligate federal agencies to follow states’
    environmental laws, the Corps was at an impasse.
    Accordingly, it invoked the exemption set forth in Section
    404(t) in the spring of 2009. That provision provides: “This
    section shall not be construed as affecting or impairing the
    authority of the Secretary to maintain navigation.” CWA
    §404(t) (codified at 
    33 U.S.C. § 1344
    (t)). On April 30, 2009,
    the Assistant Secretary of the Army for Civil Works signed a
    Memorandum of Record declaring the “failure to construct
    the 45’ Project as authorized by Congress in 1992 has . . .
    impaired the Secretary of the Army’s authority to maintain
    navigation . . . .” The Assistant Secretary was “direct[ing] the
    Corps to proceed with construction of the project.” The
    Memorandum of Record cited Section 404(t) of the CWA as
    the authoritative basis for its action.
    for the use of subaqueous lands and wetlands, neither of
    which is approved by the EPA under § 1342. Accordingly,
    the Delaware Subaqueous Lands and Wetlands Acts are
    “other state requirements” that do not fall under Section
    404(r) and that holders of federally-issued permits are
    required to follow. See 
    33 C.F.R. § 323.4
    (d) (“Federal
    projects which qualify under the criteria contained in section
    404(r) of the CWA are exempt from section 404 permit
    requirements, but may be subject to other State and Federal
    requirements.”).
    57
    The Corps’ invocation of Section 404(t) was entitled to
    Skidmore deference. In cases involving an agency’s legal
    interpretation of a statute, the amount of deference afforded is
    governed by the Chevron framework. First, a court asks
    “whether Congress has directly spoken to the precise question
    at issue.” Chevron, USA, Inc. v. Natural Res. Def. Council,
    
    467 U.S. 837
    , 842 (1984). “If the intent of Congress is clear,
    that is the end of the matter; for the court, as well as the
    agency, must give effect to the unambiguously expressed
    intent of Congress.” 
    Id. at 842-43
    . Second, a court asks
    whether, if the statute is ambiguous, the agency has rendered
    “a permissible construction.” 
    Id. at 843
    . A court is more
    likely to find the agency’s interpretation permissible if there
    is a “complex and highly technical regulatory program,”
    Robert Wood Johnson Univ. Hosp. v. Thompson, 
    297 F.3d 273
    , 282 (3d Cir. 2002) (citations and quotation marks
    omitted), or if the agency has employed formal procedures,
    such as notice and comment rulemaking, see Christensen v.
    Harris Cnty., 
    529 U.S. 576
    , 587 (2000). If the court declines
    to extend Chevron deference, it may nonetheless extend a
    lesser degree deference under Skidmore v. Swift & Co., 
    323 U.S. 134
     (1944).
    Before resorting to Skidmore deference, we observe
    that it is likely the phrase “maintain navigation” encompasses
    activities, such as the deepening project, that improve a body
    of water in order to keep navigation levels steady in light of
    changes to commercial markets, technology, and
    environmental conditions. While neither “maintain
    navigation” nor its component words are explicitly defined in
    the Clean Water Act, there is no evidence that Congress
    58
    intended the phrase to encompass only those activities that
    preserve bodies of water as they existed in 1977, when the
    statutory language was inserted. See Clean Water Act of
    1977, Pub. L. No. 95-217, 
    91 Stat. 1566
    . Arguably, such a
    reading would be irrational. Given that navigation evolves
    over time, limiting the Corps to preserving rivers as they were
    in 1977 could have the counter-productive effect of
    preventing it from “maintaining” ship traffic. The dictionary
    definitions also suggest the phrase reaches improvement
    projects. “Maintain” is defined as “to keep in an existing state
    (as of repair, efficiency or validity): preserve from failure or
    decline,” and “navigation” as “ship traffic or commerce.” See
    Merriam-Webster’s Collegiate Dictionary (11th ed. 2005).
    These are capacious definitions; preserving “ship traffic”
    from “failure or decline” could call for a wide range of
    activities,    including     repairs,     modifications,    and
    improvements.
    Nonetheless, were we to find the statutory text
    ambiguous, Skidmore deference would be warranted and
    would support the Corps’ action. 25 A court will afford
    25
    We need not decide whether Chevron deference should
    attach. Riverkeeper contends it should not, given the
    informality of the agency’s action. Namely, it points out that
    the Corps did not engage in notice and comment rulemaking
    when it invoked Section 404(t), but acted on the basis of a
    Memorandum of Record. See United States v. Mead Corp.,
    
    533 U.S. 218
    , 230-31 (2001) (holding “the want of” notice
    and comment procedures often compels in favor of not
    deferring to the agency). We need not settle this debate. At
    59
    Skidmore deference upon consideration of “the thoroughness
    evident in [an agency’s] consideration, the validity of its
    reasoning, its consistency with earlier and later
    pronouncements, and all those factors which give it power to
    persuade, if lacking power to control.” Skidmore, 
    323 U.S. at 140
    . The most important considerations are whether the
    agency’s interpretation “is consistent and contemporaneous
    with other pronouncements of the agency and whether it is
    reasonable given the language and purpose of the Act.”
    Cleary ex. rel. Cleary v. Waldman, 
    167 F.3d 801
    , 808 (3d Cir.
    1999). The Corps’ interpretation of Section 404(t) is entitled
    to deference under these standards. Its reading did not
    contradict any of the agency’s prior statements about Section
    404(t) – the Corps had only once before invoked the
    exception, and in a context different from but not in conflict
    with that here. See In re Operation of Mo. River Sys. Litig.,
    418 F.3d at 915 (affirming the Corps’ invocation of Section
    404(t) to release water from a reservoir and support
    downstream navigation in the Missouri River). The
    interpretation also was reasonable “given the language and
    purpose” of the statute, because the view that “maintain
    navigation” extends to activities necessary to maintain current
    levels of ship traffic, which is what the EA forecasted the
    project would do by enabling shippers to employ a larger
    vessel fleet, see supra note 5, is consistent with the plain
    meaning of “maintain” – i.e., to “preserve from failure or
    the least, Skidmore deference is due, and is sufficient to
    support the Corps’ action.
    60
    decline.” Finally, the canon that “[w]aivers of immunity must
    be construed strictly in favor of the sovereign,” see U.S. Dep’t
    of Energy v. Ohio, 
    503 U.S. 607
    , 615 (1992) (internal
    quotation marks and citation omitted), supports the Corps’
    interpretation. Allowing “maintain navigation” to encompass
    the deepening project would have the effect of limiting the
    federal government’s waiver of sovereign immunity in the
    first part of Section 404(t).
    Riverkeeper contends Skidmore deference is improper.
    First, it argues that Congress intended Section 404(t)’s
    “maintain navigation” authority to be “linked with the Corps’
    historical authorities under the Rivers and Harbors Act of
    1899 . . . . to maintain navigation by preventing the
    obstruction of navigable waterways.” Riverkeeper Br. at 47.
    In other words, Congress only intended for “maintain
    navigation” to protect the Corps’ mandate to do things it did
    in 1899 – such as removing physical blockages from rivers or
    preventing activities that would impede the flow of
    waterborne commerce. The statutory language, however,
    suggests the opposite. Congress did not include a reference to
    the Rivers and Harbors Act in the text of Section 404(t) as it
    had done when it codified Section 511 in 1972. Compare
    CWA § 404(t) (“This section shall not be construed as
    affecting or impairing the authority of the Secretary to
    maintain navigation.”), with CWA § 511(a)(2) (“This chapter
    shall not be construed as . . . affecting or impairing the
    authority of the Secretary of the Army (A) to maintain
    navigation or (B) under the Act of March 3, 1899[.]”). This
    shows that if anything, Congress intended Section 404(t) to
    reach more broadly than the programs the Corps managed in
    61
    1899 and to encompass the full scope of the Corps’ activities
    in 1977. 26
    26
    Furthermore, the Corps had significantly broader authority
    in 1899 than Riverkeeper acknowledges. The Rivers and
    Harbors Act contains twenty-eight pages of appropriations to
    the Corps for conducting “improvement” projects in the
    nation’s waterways. See Rivers and Harbors Act of 1899, ch.
    425, 
    30 Stat. 1121
    , 1121-1149 (“Be it enacted . . . [t]hat the
    following sums of money be, and are hereby, appropriated . . .
    to be expended under the direction of the Secretary of War

    Finding the Corps’ interpretation of Section 404(t)
    worthy of deference under Skidmore, our final step is to
    determine whether the agency’s invocation of the exemption
    was arbitrary or capricious. See 
    5 U.S.C. §706
    (2)(A); Robert
    Wood Johnson Univ. Hosp., 
    297 F.3d at 284
    . It was neither.
    After studying commerce patterns in the Delaware River for
    two decades and publishing three extensive reports, in 1992,
    1997, and 2009, the Corps concluded a five foot deepening
    project was necessary to preserve the current flow of
    navigation in the Delaware River. As the EA put it, this
    project was essential to “improve the economic efficiency of
    ships moving through the Delaware ports,” help shippers
    “more efficiently apportion operating costs,” and “allow
    current dry bulk and container vessels to carry more cargo as
    well as allow a fleet shift in the charger dry bulk market.” The
    Corps’ consideration of the issue was “thorough” and its
    determination was reasonable. See Skidmore, 
    323 U.S. at 140
    .
    Meanwhile, Delaware had sat on its permit application for
    eight years and, in December 2008, told the Corps it would
    need to submit an entirely new application. Given that the
    first phase of the project was scheduled, as of April 2009, to
    begin in August 2009, the Corps was warranted in invoking
    Ship Channel . . . by dredging or otherwise . . . . Deepening
    the channel from Galveston Harbor to Texas City, Texas . . .
    .” (emphases added)). Accordingly, even if Sections 511 or
    404(t) of the CWA circumscribed the Corps’ “maintain
    navigation” authority to its historical authorities in 1899, the
    latter included the execution of improvement and channel
    deepening projects.
    63
    the exception to save the project from postponement or
    indefinite delay.
    V.
    New Jersey contends the Corps acted arbitrarily and
    capriciously under the Coastal Zone Management Act when it
    decided, as memorialized in a Memorandum of Record issued
    on November 9, 2009, to proceed with the project without
    providing supplemental consistency determinations to
    Delaware or New Jersey. Because “significant new
    information” had become available since the Corps submitted
    its initial CZMA determinations in 1997, New Jersey
    contends, supplemental determinations were required.
    According to New Jersey, the Corps’ conclusion to the
    contrary was arbitrary and capricious because it was
    grounded in the procedurally and substantively flawed EA.
    A.
    The Coastal Zone Management Act of 1972 was
    enacted “to preserve, protect, develop, and where possible, to
    restore or enhance, the resources of the Nation’s coastal zone
    for this and succeeding generations,” and to “encourage and
    assist the states to exercise effectively their responsibilities in
    the coastal zone through the development and implementation
    of management programs to achieve wise use of the land and
    water resources of the coastal zone[.]” 
    16 U.S.C. § 1452
    (1),
    (2). States’ “management programs” must provide for “the
    protection of natural resources,” as well as “improved
    coordination between State and Federal coastal zone
    64
    management agencies.” 
    Id.
     § 1452(2)(A), (J). Federal
    agencies conducting activities “within or outside the coastal
    zone” are required to provide the relevant state(s) with a
    “determination” that the activity “shall be carried out in a
    manner which is consistent to the maximum extent
    practicable with the enforceable policies of approved State
    management programs.” Id. § 1456(c)(1)(A), (C). The
    state(s), in turn, must either concur with or object to the
    federal agency’s determination. 
    15 C.F.R. § 930.41
    (a). A
    state “cannot unilaterally place an expiration date on its
    concurrence.” 
    Id.
     § 930.41(d). Moreover, even if a state
    objects, the federal agency can proceed over the state’s
    objection if it “conclude[s] that its proposed action is fully
    consistent with the enforceable policies of the management
    program.” Id. § 930.43(d)(2).
    The CZMA regulations require federal agencies to
    supplement their consistency determinations if “the proposed
    activity will affects any coastal use or resource substantially
    different than originally described.” Id. § 930.46(a).
    “Substantially different” effects are “reasonably forseeable,”
    and thereby warrant a supplemental determination, if: (1) the
    agency “makes substantial changes in the proposed activity
    that are relevant to the manageable program enforceable
    policies”; or (2) there are “significant new circumstances or
    information relevant to the proposed activity and [its] effect
    on any coastal use or resources.” Id. § 930.46(a)(1), (2).
    B.
    The Corps’ conclusion in the Memorandum of Record
    65
    that it need not provide supplemental consistency
    determinations to either state under the CZMA was
    reasonable. Federal agencies are required to submit
    supplemental determinations in either of two instances: if the
    agency makes “substantial changes in the proposed activity,”
    or if “significant new circumstances or information relevant
    to the proposed activity and [its] effect on any coastal use or
    resource” arise. Id. § 930.46(a)(1), (2). Relying on the EA,
    the Corps concluded neither situation was present. With
    respect to “substantial changes” to the project, the
    Memorandum of Record identified three alterations that had
    been made since 1997, when the original CZMA consistency
    determinations were transmitted: (i) four disposal sites
    identified in the SEIS had been eliminated; (ii) sand would
    now be deposited directly onto Broadkill Beach, rather than
    initially stockpiled offshore; and (iii) a planned beneficial use
    site at Egg Point Island was no longer needed. None of these
    changes were “substantial,” the Corps determined, because
    the 2009 EA had found that none would cause serious
    impacts to the environment. With respect to “significant new
    circumstances or information,” the Memorandum of Record
    noted both the oil spill of 2004 and the recent surveys
    showing an expansion of the shortnose sturgeon in the region.
    But again, relying on the EA and a 2009 Biological
    Assessment the agency prepared for NMFS, the Corps
    concluded neither development was “significant” because
    neither would cause adverse environmental consequences not
    anticipated in the SEIS. The Corps was justified in relying on
    these recent and thorough reports. See supra. The agency’s
    conclusion that 
    15 C.F.R. § 930.46
    (a) had been satisfied, and
    66
    that no supplemental consistency determinations were
    required, was neither arbitrary nor capricious.
    VI.
    For over twenty years, the Corps has devoted
    substantial efforts to evaluating the proposed five foot
    deepening project for the Delaware River. It has published
    three comprehensive NEPA reports, received multiple rounds
    of public comments, and had immeasurable communications
    with the relevant state and federal agencies. Its decision in
    2009 to proceed with the project was consistent with NEPA,
    the CWA, and the CZMA. Accordingly, we will affirm the
    judgments of the District Courts of New Jersey and Delaware.
