OPINION AND ORDER

SCHEINDLIN, District Judge.

I. INTRODUCTION

Plaintiffs are a group of environmental organizations and concerned citizens. They are challenging an ongoing project, to be carried out by the Army Corps of Engineers (“Army Corps”), to deepen shipping channels in the New York-New Jersey Harbor through dredging and blasting of the Harbor floor. The Harbor Deepening Project (“HDP”) is intended to open the Harbor to the newer, larger and deeper-bottomed cargo vessels on which the modern shipping industry depends. Part of the HDP will cut through highly contaminated sections of Newark Bay and surrounding waterways. This contamination is the result of centuries of heavy industrial use of the Bay and its tributaries — in particular, the Bay is contaminated with the by-products resulting from the manufacturing of Agent Orange at the Diamond Alkali Chemical Plant, on the Passaic River, during the Vietnam War.

On February 13, 2004, the United States Environmental Protection Agency (“EPA”) entered into an Administrative Order on Consent (“Feb.2004 AOC”), which added Newark Bay to the Diamond Alkali Superfund Site, as the “Newark Bay Study Area of the Diamond Alkali Superfund Site.” The AOC orders a Remedial Investigation/Feasibility Study (“RI/FS”) to be carried out by Occidental Chemical Corporation under the supervision of the EPA. The RI will determine the extent and nature of contamination in the Bay, and the FS, based on what is learned from'the RI, will evaluate possible cleanup options. Both aspects of the study are to begin in the summer of 2005. An essential component of the study is the sampling of the Bay’s water to determine the distribution and concentration of contaminated sediments.

Plaintiffs believe that the HDP may delay or frustrate this sampling effort, by disturbing and resuspending 1 the contaminated sediments that are to be sampled, undermining the study’s attempt to map contaminant distribution — thereby delaying or even preventing the design of effective cleanup options. They insist that the Corps is acting arbitrarily and capriciously, in violation of the National Environmental Policy Act (“NEPA”), 42 U.S.C. §§ 4321 et seq., and the Administrative Procedure Act, 5 U.S.C. § 706 (“APA”), by proceeding with the HDP without preparing a Supplemental Environmental Impact Statement (“SEIS”) to consider the possible detrimental effects of the HDP dredging on the RI/FS. The Corps argues that dredging will not significantly interfere with sampling for the RI/FS, and so there is no reason to prepare an SEIS.

The narrow issue presented here is whether the Army Corps gave a “hard look” to the possibility that the HDP will interfere with the sampling required by the RI/FS, and to ways of avoiding such interference, before deciding to go ahead with dredging without preparing an SEIS. If the Corps failed to take that hard look, its decision, by definition, was arbitrary and capricious.

After closely reviewing a voluminous record, I conclude that the Corps failed to take a hard look at this narrow question. Because the sampling will ultimately be important in determining the need for a clean-up of the Bay, and the best way to approach that clean-up, it is important that any action that might adversely affect it be carefully considered. The issue is a narrow one, and it may be that, once the Corps does take a hard look at the possible effects of dredging on the RI/FS, it will find — as it hopes — that they are minor and easily controlled by cooperation between the Corps and the EPA, and that preparing an SEIS would merely result in burden and delay. But the issue is too important to be treated lightly. NEPA ensures that federal agencies must take a hard look at potential environmental problems before proceeding with their plans. The Corps must assess the impact of its dredging on the sampling required for the RI/FS before committing to a particular method of dredging, rather than waiting until dredging interferes with that sampling and causes unrecoverable delays to the potential cleanup process. Similarly, if the Corps relies on the promise of cooperation between the EPA and the Corps to minimize the effects of dredging on the RI/FS, the Corps must give full consideration to how that cooperation will be handled before committing to a particular method of dredging, not after problems arise. For the reasons set forth below, the Corps’ decision to begin dredging without taking the required hard look at this problem was arbitrary and capricious.

The issue is before the Court on plaintiffs’ and defendants’ 2 cross-motions for summary judgment. Pursuant to the agreement of the parties, the Court has bifurcated review of plaintiffs’ claims. This opinion addresses only the question of liability — that is, whether the Corps’ decisions to proceed with the HDP without preparing an SEIS were based on adequate review of the environmental consequences of the HDP, as required by NEPA and the APA. I find that they were not, and the Corps is in violation of NEPA and the APA. The question of what remedy (if any) is necessary will be addressed in a subsequent opinion.

II. BACKGROUND

A. The Newark Bay Site

On September 21, 1984, the EPA added the Diamond Alkali Superfund Site to the National Priorities List, pursuant to the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”). 3 The site consisted of the former Diamond Alkali chemical manufacturing plant and the adjacent property. The EPA’s RI/FS revealed that the site was highly contaminated with toxic substances, including dioxin, a by-product of the Agent Orange manufacturing carried out at the plant during the Vietnam War. 4

The EPA’s investigations also revealed hazardous substances in the sediments of the Passaic River. 5 These findings resulted in the EPA entering into an AOC, dated April 20, 1994, with Occidental Chemical Corporation (“Occidental”), the company responsible for the plant site. The 1994 AOC required Occidental to conduct an RI of a six mile stretch of the Passaic River, up and downstream from the plant site. 6 In 2003, the EPA determined that an expanded RI for a 17-mile stretch of the River (the “Lower Passaic River Study Area”) was necessary. The EPA, the Army Corps, and the New Jersey Department of Transportation have entered into a partnership, the Lower Passaic River Restoration Project, to “identify and address water quality improvement, remediation and restoration opportunities” in the Passaic River. 7 On June 22, 2004, the EPA entered into an AOC with thirty-one potentially responsible parties to fund the EPA’s investigation of the Lower Pas saic River Study Area. 8 The Lower Passaic River Study Area ends at the mouth of the River. 9 To date, no remedy has been determined for the Lower Passaic River Study Area. 10

On November 19, 2003, plaintiffs NRDC and Raritan Baykeeper, Inc. (“Baykeeper”), served a notice of intent to sue Occidental under the Resource Conservation and Recovery Act, to compel a study of dioxin contamination in Newark Bay, which they allege had spread downstream from the Passaic River portion of the Diamond Alkali Superfund Site. 11 On February 13, 2004, the EPA entered into another AOC with Occidental under CERCLA. 12 The February 2004 AOC designated Newark Bay and portions of the Hackensack River and the Arthur Kill and Kill van Kull channels as the Newark Bay Study Area of the Diamond Alkali Superfund Site (the “Newark Bay Study Area”). 13 Pursuant to the AOC, the EPA “has determined that conditions in the Newark Bay Study Area may present an imminent and substantial endangerment to public health, welfare or the environment.” 14

Under the terms of the AOC, Occidental has undertaken to perform an RI/FS in the Newark Bay Study Area, under the supervision of the EPA, “to determine the nature and extent of contamination ... and to develop and evaluate remedial alternatives.” 15 Among other things, the RI will “determine the [] distribution and concentration of [contaminants] for the Newark Bay Study Area sediments,” in order to “identify ‘hot spots’ for potential short term action!;] identify potential exposure concentrations through the food chain for human and ecological receptors [and] evaluate prospective remedial alternatives.” 16 In addition, the RI will “determine the primary human and ecological receptors of [contaminated sediments] in the Newark Bay Study Area” and “determine the direct and indirect continuing sources of [contaminants] to the sediments in the Newark Bay Study Area.” 17 The FS will evaluate a range of possible remedial actions, from “[treatment alternatives for source control of contaminated [sediments] that would eliminate the need for long term management,” through “[a]n alternative that involves containment of waste with little or no treatment,” to “[a] no action alternative.” 18 A company known as Tierra Solutions, Inc., (“Tierra”) is performing the work under the AOC on behalf of Occidental. 19

Occidental submitted a draft work plan to conduct the RI for the Newark Bay Study Area in June 2004. 20 The draft RI/FS contains a draft Inventory Report (the “June 2004 Inventory Report”) compiling data on contaminated sediment, flora and fauna, and water in and around Newark Bay. 21 The plan is subject to the approval of the EPA. Based on public comments, the EPA anticipates that the draft work plan will need modification. 22 The EPA is revising the study, with the intention of beginning field sampling of contaminated sediments in the Newark Bay Study Area in the summer of 2005. 23

B. The Harbor Bay Deepening Project

The Port of New York and New Jersey (“the Port”) is the third largest in the nation. 24 In 2004, $114 billion in cargo passed through the Port. 25 A 2001 study conducted by the Center for Urban Policy Research at Rutgers University found that

cargo movement in 2000 provided nearly 101,700 direct full-time equivalent jobs and supported an additional 125,585 indirect full-time equivalent jobs in the 26-county metropolitan region. Furthermore, the goods movement thru the port region supported an additional 185,-715 jobs elsewhere in the nation (not including the jobs of people producing goods shipped). 26

In recent years, under the pressure of globalization, the ocean carrier industry has seen a movement toward the concentration of capacity in fewer ships and ports. 27 At the same time, there has been a trend toward the development of larger cargo vessels, capable of carrying cargo more efficiently and achieving economies of scale. 28 The navigation channels in the Harbor are not presently deep enough to serve fully loaded ships of the latest design. 29

Beginning in 1986, Congress has authorized the Army Corps to undertake a number of projects to deepen the navigational channels in the New York and New Jersey Harbor. 30 These projects included the Kill Van Kull 45' Deepening Project, the Arthur Kill 41/40 Deepening Project, The Port Jersey 41' Deepening Project, and the New York and New Jersey Harbor Deepening Project. 31 In 2002, Congress ordered the Army Corps to consolidate each of these projects into one overall deepening project, known as the HDP. 32 The HDP will deepen all of the navigational channels in the New York and New Jersey Harbor to 50 feet. 33

C. NEPA Review of the Harbor Deepening Project

The various phases of the HDP have been subjected to extensive environmental review under NEPA and under section 401 of the Clean Water Act, 33 U.S.C. § 1341. In total, the Army Corps has produced over a dozen separate NEPA documents analyzing the project, beginning with a 1980 Final Environmental Statement. 34 The most important of these is a Final Environmental Impact Statement (“FEIS”), issued by the Army Corps in December 1999, to “identify, screen, evaluate and recommend a plan for channel improvements throughout the Port of New York and New Jersey.” 35 Among other factors, the 1999 FEIS analyzed the environmental effects of resuspension of contaminated sediments as a result of dredging, and the potential effects of such resuspension on “exposure of biological receptors to contaminants.” 36 The FEIS concluded that:

two opposing effects on biological exposure to contaminants are anticipated from deepening the navigation channels in the New York and New Jersey Harbor. Dredging of the channels, and the resulting suspension of contaminated sediments into the water column, is expected to increase exposure of biological organisms. This is expected to occur, however, only in areas close to the dredging operations and should be relatively short-lived because suspended sediments are expected to settle out of the water column within a relatively short period. Furthermore, sediment suspension from ship traffic in narrow channels has been shown to be greater than from dredging activities. It is therefore possible that any increase in exposure due to dredging will be minimal compared to other more frequent disturbances in the Harbor. On the other hand, dredging the channels is also expected to remove a large amount of contaminated sediments from the bottom of the channels, thus exposing a new layer of relatively clean sediment. This effect, however, is also expected to be short-lived ... [T]he system should stabilize and return to current conditions within a few months to a few years, depending on the area of the Harbor. Furthermore, Best Management Practices (BMPs) will be used during dredging operations to minimize the suspension of sediments ... In addition, sediment contaminant analysis, where necessary, will be performed for the next phase of the project, and will be coordinated with the appropriate regulatory authorities. 37

In 2001, the Army Corps signed a Preconstruction Engineering and Design Agreement with the Port Authority of New York and New Jersey. 38 Pursuant to Army Corps regulations, the Army Corps updated its environmental analysis of re-suspension of sediments resulting from dredging operations. 39 The Army Corps updated its environmental analysis again following the 2002 consolidation of the various projects into the HDP. Because the consolidation resulted in some changes to the design of the project, and additional deepening in some areas, the Army Corps conducted an Environmental Assessment (“EA”). 40 The public comment period for this EA opened in November, 2003. 41 In January 2004, the Army Corps issued its Limited Reevaluation Report and EA, with a Finding of No Significant Impact (“FONSI”). 42 The EA/LRR found that “[d]ata comparison and evaluation identi fied no new potential adverse environmental impacts attributable to consolidation. Potential short term impacts due to consolidated implementation would be the same as the effects on aquatic resources identified in the [prior EIS], except the overall duration under a consolidated schedule would be shorter.” 43

D. Clean Water Act Review of the Harbor Deepening Projects

In addition to its obligations under NEPA, the Army Corps applied, pursuant to the Clean Water Act, for “umbrella” Water Quality Certificates (“WQCs”) from the States of New York and New Jersey, as part of the approval process for the HDP. 44 Following formal public hearings on February 12, 2004 in Staten Island, New York and March 10, 2004 in Bayonne, New Jersey, the Army Corps received WQCs from both states. 45 The WQCs impose extensive “Special Conditions” on the dredging practices used in the deepening projects. 46 For example, the WQC issued by New York specifies the type of “environmental bucket” to be used for dredging. 47 The WQCs also require ongoing monitoring of certain environmental impacts and the submission of additional “Permit Documents.” Among other things, the New York WQC requires that “a sediment sampling plan for purposes of conducting bulk chemistry analysis for each contract reach be submitted for [New York State Department of Environmental Conservation] approval in coordination with the State of New Jersey at least 60 days prior to the anticipated start date for a given reach.” 48

E. Environmental Review Following the February 2004 AOC

On February 13, 2004, the EPA informed the Army Corps by email that the AOC designating the Newark Bay Study Area had been signed. 49 An Army Corps employee named Thomas Shea, at the time the manager of the Lower Passaic River project, and now manager of the HDP, responded to that email on February 17, 2004, asking “[w]hat impact does this have on our navigation jobs, where we are dredging portions of Newark Bay?” 50 On March 11, 2004, Shea circulated the AOC to twenty-one Army Corps employees. 51 Shea noted that “As a result of this order, I have some basic questions on what this may mean to our various programs (predominantly our ... deepening projects ...).... Could you please review the order and develop your own set of questions and send them to me. I will consolidate them and EPA will review and meet with us to discuss them.” 52 Shea received several responses, although none substantive ly addressing the effect of dredging on the RI/FS. 53

In May, and again in October, Elizabeth Butler of the EPA attempted, by email, to arrange a meeting with-Shea to discuss coordination between the Army Corps’ and the EPA’s activities in the Bay. 54 In the meantime, in May and September 2004, plaintiffs raised their concerns with the EPA and the Army Corps, by letter, email and orally. 55 Notably, in a May 3, 2004 email to Shea, Baykeeper requested, a meeting “to discuss [Army Corps] coordination with EPA, especially with respect to dredging in Newark Bay and other areas under study under the guise of CERCLA.” 56 In a September 28, 2004 letter to the EPA (and copied to the Army Corps), NRDC and Baykeeper presented a detailed list of objections to Tierra’s draft work plan for the RI/FS; among other things, plaintiffs complained that Tierra’s work plan failed to consider the “obvious overlap” between their sampling activities and the Army Corps’ dredging. 57

On October 18, 2004, representatives of the EPA and the Army Corps finally met to discuss the deepening projects. 58 At that meeting, the - Army Corps provided EPA with a preliminary schedule and map of planned deepening projects to assist with the coordination of the projects. 59 During the following months, the EPA and the Army Corps continued to communicate, while plaintiffs continued to press their concern. On November 24, 2004, plaintiffs wrote to Colonel Richard J. Polo, Commander and District Engineer of the Army Corps, New York District, to request a meeting to discuss their fear that dredging would “undermine the viability” of the RI to be conducted in the Bay, and “by interfering with the study [, would] delay or prevent an effective Superfund cleanup of contaminated sediments.” 60

Internal Army Corps memoranda from early December record conversations between the EPA and the Army Corps. One of these memos records that the EPA informed the Corps that “Newark Bay is not officially part of a Supérfund Site yet, but after the Sampling effort is completed [] and Remedial Investigation/Feasibility Study report is done it will most likely be designated as a site.” 61 According to the memo, the EPA “would like to get a better handle on .our dredging schedule to coordinate there [sic] sampling efforts.” 62 A second memo records that the EPA stated that “whether Newark Bay is designated a Superfund Site will not prevent all activity, such as harbor deepening. If it is designated a Superfund Site, EPA will likely look to the Hudson River (a Superfund Site that was dredged) to determine how to approach Newark Bay.” 63

On December 6, 2004, officials of the Corps and the EPA met to discuss NRDC’s concerns regárding the impact of the Army Corps’ dredging on the EPA’s sampling activities. 64 Army Corps memoranda prepared by Shea and by another Corps project manager, Scott Nicholson, summarized the “key points/conclusions” of the meeting: specifically, that’ “[t]he EPA is in the early stages of determining what studies are needed to determine the [] extent [] of hazardous material and what remediation methods should be performed, if warranted;” and that “[t]he EPA saw no reason for the USACE to stop any of its navigation projects.” 65 The EPA

noted that just because EPA designated an area for study, it does not mean you cannot dredge. They felt that the claim that dredging would exacerbate the imminent and substantial endangerment to human health was not accurate based on previous sampling and dredging. In this context, they also noted that there was no new information that was found and used for the Newark AOC that would affect that understanding. In addition, based on- existing information and ongoing coordination, the dredging planned for the HDP in Newark Bay would not delay or prevent an effective cleanup or exacerbate existing conditions. 66

However, the EPA “would not comment on [the Army Corps’] need for additional NEPA documentation. They stated that this was a USACE decision to make.” 67 On December 8, 2004, Army Corps staff, including Polo, met with representatives of plaintiffs and the EPA, at the request of NRDC, to discuss dredging methods. 68 The following day, the Army Corps initiated a team review by its NEPA specialists to determine whether further NEPA review was required. 69 The results of this review are documented in a memorandum dated December 16, 2004. 70 As part of this review, the Corps reviewed its NEPA documents prepared since 1999. 71 The Corps also re-evaluated its methods for minimizing resuspension of sediment in dredging. 72 In addition, the Corps compared the dredging methods to be used in Newark Bay with those used in the Hudson River, a Superfund site in which General Electric will be performing a cleanup of PCB-contaminated material, a process which will include remedial dredging and a limited amount of navigational dredging. 73 The Corps concluded that the dredging methods and “resuspension control technologies” used in the Hudson River, to the extent that they differed from those planned for Newark Bay, were “a poor fit for our project” or unsuited to navigable waters. 74 Finally, the Corps contacted its New England District to discuss the dredging methods used in a Superfund cleanup in New Bedford Harbor, Massachusetts. 75

Ultimately, the Corps concluded that “the Newark Bay issue was addressed in detail in the EIS, and no substantial changes in the physical or chemical nature of its sediments in the project occurred as a result of the AOC. Therefore all analyses conducted and conclusions derived from them in the original EIS are still valid.” 76 Because “there have been no substantial changes in existing conditions or project plans as a result of the ACO [sic, AOC],” the Corps further concluded that there was no need to prepare an SEIS. 77 However, “in that CERCLA designation may be perceived by the public as significant of itself, the District should, in the interest of full public disclosure, prepare an EA/FON-SI to document why no further supplemental EIS is needed.” 78 Shortly afterwards, on December 29, 2004, the Corps awarded the first contract for dredging in the Arthur Kill Channel. 79

On January 4, 2005, NRDC served the Corps with a notice of intent (“NOI”) to sue, demanding that the Corps prepare an SEIS. 80 On February 16, 2005, plaintiffs moved for a preliminary injunction halting the HDP. The Corps formed another environmental review team to analyze plaintiffs’ arguments, including plaintiffs’ concern that dredging would interfere with the study phase of the RI/FS, and two environmental reports that plaintiffs claimed contained new information. 81

On February 28,. 2005, the Corps released an SOF, which concluded that were no significant new circumstances or information that would require preparation of an SEIS. 82 In that Statement, the Corps determined that the new reports relied on by plaintiffs contained no new significant new information. 83 The SOF, and the documents attached thereto, also reviewed the Corps’ dredging methods, its coordination with the EPA, its ongoing monitoring obligations under its WQCs, and the dredging methods used by the Corps’ New England District in Superfund cleanup sites. 84 In a declaration prepared in opposition to plaintiffs’ motion for a preliminary injunction, Dr. Robert M. Engler, a Senior Scientist (Environmental) for the Army Corps, summarized his finding that dredging would not “negatively impact proposed Superfund investigations.” 85 Dr. Engler also found that:

Based on field observations; the nature of contaminant mobilization; modeling; operational requirements of the dredge; surveys of the distribution and magnitude of contaminant concentration; physical, chemical and toxicological assessments; and overall knowledge of the entire estuary — all of which have been evaluated by USACE — the preponderance of evidence and experience in this system indicates that resuspended sediments from dredging will be minimal (particularly when compared to other sources of resuspension). Similarly, re-suspension will be short-lived, and generally limited to the immediate vicinity of the dredging operation.... Moreover, resuspension from a properly operated environmental dredge will usually be less than 1 percent of the total amount dredged. 86

Ultimately, the Corps concluded that there were no significant new data or circumstances that would require preparation of an SEIS. 87 On March 11, 2005, the Army Corps awarded the first contract for dredging in the Kill van Kull Channel. 88

III. LEGAL STANDARD

A. The Procedural Requirements of NEPA

The procedural requirements of NEPA are intended to ensure that the “broad national commitment to protecting and promoting environmental quality [ ] is ‘infused into the ongoing programs and actions of the Federal Government.’ ” 89 Among other requirements, NEPA directs that all federal agencies must, for every major federal action significantly affecting the quality of the human environment, prepare a detailed EIS. 90 The EIS must examine 1) the environmental impact of the proposed action; 2) any adverse environmental effects which cannot be avoided should the proposal be implemented; 3) alternatives to the proposed action; 4) the relationship between local short-term uses of the environment and the maintenance and enhancement of long-term productivity; and 5) any irreversible and irretrievable commitments of resources that would be involved in the proposed action should it be implemented. 91 This statutory requirement

ensures that the agency, in reaching its decision, will have available, and will carefully consider, detailed information concerning significant environmental impacts; it also guarantees that the relevant information will be made available to the larger audience that may also play a role in both the decisionmaking process and the implementation of that decision. 92

If the agency is uncertain whether the impacts rise to the level of a major federal action requiring an EIS, the regulations of the Council on Environmental Quality (the “CEQ”) 93 require that the agency must prepare an EA. 94 An EA is “a concise document that briefly discusses the relevant issues and either reaches a conclusion that preparation of [an] EIS is necessary or concludes with a FONSI, in which case preparation of an EIS is unnecessary.” 95 “When the determination that a significant impact will or will not result from the proposed action is a close call, an EIS should be prepared.” 96 “The fact that effects are only a possibility does not insulate the proposed action from consideration under NEPA, but it does accord an agency some latitude in determining whether the risk is sufficient to require preparation of an EIS.” 97

An agency’s obligations under NEPA do not end with the preparation of an EIS. The agency may be required to prepare an SEIS “if there ‘are significant new circumstances or information relevant to environmental concerns and bearing on the proposed action or its impacts.’ ” 98 An agency’s determination whether to prepare an SEIS in light of new information or circumstances is governed by a “rule of reason.” 99 “[A]n agency need not supplement an EIS every time new information comes to light after the EIS is finalized. To require otherwise would render agency decisionmaking intractable.” 100 However, an agency must prepare an SEIS whenever major federal action is yet to occur which the new information shows will affect the quality of the human environment in a significant manner or to a significant extent not already considered. 101 As with the decision to prepare an EIS, “[c]lose calls should be resolved in favor of preparing a SEIS.” 102 If the agency determines that new information is not sufficiently significant to require an SEIS, the agency is not necessarily required to produce a formal NEPA document explaining its decision. 103

Ultimately, “NEPA is a procedural statute that mandates a process rather than a particular result.” 104 “The only role for a court is to insure that the agency has taken a ‘hard look’ at environmental consequences; it cannot ‘interject itself within the area of discretion of the executive as to the choice of the action to be taken.’ ” 105 As long as the agency has given adequate consideration to the environmental consequences of its actions, NEPA does not preclude it from “deciding that other values outweigh the environmental costs.” 106

B. The Standard of Review

The Administrative Procedure Act governs judicial review of an agency’s compliance with NEPA. 107 That Act provides that a reviewing court shall “hold unlawful and set aside agency action, findings, and conclusions found to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, ... [or] without observance of procedure required by law.” 108 “[A]n agency decision is entitled to a presumption of regularity, and the burden of proof is on the party challenging the agency’s decision.” 109

Review of an agency’s decision not to supplement an EIS is controlled by the ‘arbitrary and capricious’ standard of § 706(2)(A) of the APA. 110 A reviewing court must make a “searching and careful” inquiry into “whether the decision was based on a consideration of the relevant factors and whether there has been a clear error of judgment.” 111 In the Second Circuit, this review has two steps. First, the court considers “whether the agency took a ‘hard look’ at the possible effects of the proposed action.” 112 Second, if the court is satisfied that the agency took a hard look, the court must determine “whether the agency’s decision was arbitrary or capricious.” 113

Although a “court may not substitute its judgment for that of the agency,” an agency decision may be set aside as arbitrary and capricious where the agency

has relied on factors which Congress has not intended it to consider, entirely failed to consider an important part of the problem, offered an explanation for its decision that runs counter • to the evidence before the agency, or is so implausible that it could not be ascribed to a difference in view or the product of agency expertise. 114

When specialists express conflicting views, the court must defer to the agency’s reliance on the reasonable opinions of its own qualified experts, “even if, as an original matter, a court might find contrary views more persuasive.” 115 “[I]t is for the agency to evaluate new information and make a reasoned determination whether it is of such significance as to require implementation of formal NEPA filing procedures.” 116 However, courts should not automatically defer to the agency “without carefully reviewing the record and satisfying themselves that the agency has made a reasoned decision based on its evaluation of the significance — or lack of significance'— of the new information.” 117

• Subject to certain exceptions, “a court reviewing an agency decision is confined to the administrative record compiled by that agency when it made the decision.” 118 The Court has already determined, in a ruling dated May 9, 2005, that there are two relevant decisions. On December 29, 2004, the Army Corps awarded a contract with respect to the Arthur Kill 40/41 project, and thus made a decision, for purposes of NEPA, to proceed with that project without preparation of an SEIS. The adequacy of the Army Corps’ decision with respect to the Arthur Kill 40/41 project must be judged based on the record as of December 29, 2004. The Corps maintains, and this Court held in its prior ruling, that the Arthur Kill 41/40 project is separable from the remainder of the HDP. With respect to the remainder of the HDP, the relevant decision occurred on March 11, 2005, when the Corps awarded a contract for the S-KVK-2 project in the Kill van Kull Channel, a project which the Corps concedes is inseparable from the broader HDP.

This case is before the Court on the parties’ cross motions for summary judgment. Pursuant to Federal Rule of Civil Procedure 56, summary judgment should be granted only if the moving party has shown that there are no genuine issues of material fact and that the moving party is entitled to judgment as a matter of law. 119

IV. DISCUSSION

A. Standing

Although defendants do not challenge plaintiffs’ standing, “[t]he federal courts are under an independent obligation to examine their own jurisdiction, and standing ‘is perhaps the most important of [the jurisdictional] doctrines.’ ” 120

Three elements comprise the irreducible constitutional minimum of standing. First, the party seeking judicial resolu tion of its claim must have suffered an injury-in-fact — an invasion of a legally protected interest which is (a) concrete and particularized, and (b) actual or imminent, not conjectural or hypothetical. A ‘particularized’ injury is one that affects the plaintiff in a personal and individual way. Second, there must be a causal connection between the injury and the conduct complained of. Third, it must be likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision. 121

Because plaintiffs assert a violation of a procedural right under NEPA, a lesser showing of immediacy and redressability is required. Plaintiffs need not show that the preparation of an SEIS would change the Army Corps’ ultimate decision regarding the HDP, but only that “the disregard of [NEPA] could impair a separate concrete interest of [plaintiffs’].” 122

“[Environmental plaintiffs adequately allege injury in fact when they aver that they use the affected area and are persons for whom the aesthetic and recreational values of the area will be lessened by the challenged activity.” 123 The members of the plaintiff organizations, and individual plaintiff Andrew Willner, aver that they have curtailed their former use of the waterbodies in the Newark Bay Study Area for fear of pollution, which they allege will be exacerbated by the Army Corps’ decision to proceed, with the HDP without further NEPA review. 124

The plaintiff organizations have standing to bring suit on behalf of their members, because the interests the organizations seek to protect are germane to their purposes, and neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit. 125 In addition, plaintiff organizations have alleged that, due to the Army Corps’ refusal to prepare an SEIS, plaintiff organizations have diverted their resources to technical analysis of the impacts of the dredging on the Superfund site. 126 The cost of this diversion of resources is a sufficient injury to confer standing on the organization on its own behalf. 127

B. Laches

Defendants argue that plaintiffs’ claims are barred by laches. A party asserting a defense of laches must establish that “(1) the plaintiff knew of defendant’s misconduct; (2) the plaintiff inexcusably delayed in taking action; and (3) the defendant was prejudiced by the delay.” 128 “[Ljaches is a doctrine of equity that is only rarely invoked in environmental cases, on account of the strong public interest in effecting compliance with NEPA.” 129

Defendants’ argument for the application of laches rests on a misapprehension of the nature of plaintiffs’ claims. The Army Corps argues that “at its core plaintiffs’ lawsuit challenges [the Army Corps’] dredging methods and the adequacy of the Army Corps’ prior NEPA analyses.” 130 Accordingly, the Corps argues that plaintiffs delayed unreasonably between the completion of the Corps’ 1999 FEIS and the bringing of this suit. In support of this assertion, the Corps points to certain statements by plaintiff Baykeeper which suggest that Baykeeper “opposes all deepening activities within the harbors.” 131 Regardless of what plaintiffs’ broader policy ambitions may be, this lawsuit is specifically focused on the Corps’ decision to proceed with dredging without preparation of an SEIS to consider alleged new impacts resulting from the Feb. 2004 AOC. 132 The first of the challenged decisions occurred on December 29, 2004, and plaintiffs brought suit quite promptly, on January 21, 2005.

In the year following the signing of the February 2004 AOC, plaintiffs repeatedly attempted to resolve their concerns with the Army Corps and the EPA through negotiation. 133 Throughout this period, it was reasonable for plaintiffs to believe that the Corps might alter its plans without the need for litigation. 134 Plaintiffs did not unreasonably delay in bringing suit. 135 Although plaintiffs did not demand that the Corps prepare an SEIS until November 24, 2004, 136 plaintiffs in a NEPA case cannot be faulted for reasonable and good faith attempts to bring environmental considerations to the attention of the agency through methods less formal than the preparation of an SEIS.

Moreover, even if plaintiffs had delayed unreasonably, defendants have failed to make a sufficient showing of prejudice. In NEPA cases, the test of prejudice is ‘

whether the plaintiffs delay in bringing the suit has resulted in construction proceeding ‘to a point where any significant environmental damage has already been done’ and whether, in the alternative, ‘construction may have gone so far that for economic reasons it would be impracticable or impossible to alter much of the basic plan.’ 137

Plaintiffs are not attempting to put a stop to all dredging in the Bay. Rather, plaintiffs are attempting to force the Army Corps to give additional consideration to the means by which dredging is to be coordinated with the EPA’s RI/FS. The EPA’s RI/FS is an extensive, multi-year process, which has not yet begun. It is not too late for additional analysis of methods of coordination to help mitigate the impact of dredging on the RI/FS. The Army Corps claims, no doubt accurately, that “[t]he cost of [] altering these projects now is substantial,” 138 but that is far from sufficient to show that it would be “impracticable or impossible” for the Army Corps to alter its dredging methods. I note that the Army Corps, the EPA, and the state environmental authorities have committed to coordination of their activities and to ongoing monitoring and analysis of their cooperation; surely, if this ongoing cooperation is to be more than a paper exercise, the Corps must still have some flexibility to refine its dredging methods.

C. The Merits of Plaintiffs’ NEPA Claim

1. The Army Corps Was Required to Take a Hard Look at the Significance of New Circumstances

The Army Corps argues that the designation of the Newark Bay Study Area cannot be considered a “significant new circumstance” requiring the preparation of an SEIS. 139 Rather, the Army Corps contends that “at most, the designation [of Newark Bay as a Study Area under CERCLA] constitutes a change in the Bay’s legal status, which courts have not recognized as triggering the need for an SEIS.” 140 Therefore, the Army Corps argues that it was under no obligation even to take a ‘hard look’ at plaintiffs’ purported “new information.” This argument fails for two reasons.

First, the Feb. 2004 AOC represents more than a mere change in the Bay’s legal status. The AOC requires Occidental and the EPA to conduct an RI/FS in the Bay to determine what clean-up measures, if any, can be taken. 141 This is not merely a change in the label attached to the Bay; it is a physical change in the activities that will take place in the Bay.

The CEQ’s regulations require that, when an agency considers the environmental impact of its activities, it must take into account “indirect effects.” 142 Indirect effects are defined in the CEQ’s regulations as [effects] which are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable. 143 Indirect effects are defined broadly, to “include growth inducing effects and other effects related to induced changes in the pattern of land use, population density or growth rate, and related effects on air and water and other natural systems, including ecosystems.” 144 The CEQ’s regulations also require that agencies consider the “cumulative impact” of their activities — i.e., “the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (Federal or non-Federal) or person undertakes such other actions.” 145 Plaintiffs’ experts contend that the HDP will interfere with the RI/FS, and therefore will have the indirect effect of preventing the EPA from taking remedial action, or reduce the effectiveness of whatever remedial action the EPA may take. 146 If plaintiffs are correct, then the HDP may have significant new environmental consequences, whether these are seen as indirect or cumulative effects.

This case is therefore very different from Swanson v. Forest Service, 147 on which the Army Corps relies. In Swanson, the Ninth Circuit held that the change in the legal status of salmon from a “sensitive” to an “endangered” species was not a significant new circumstance requiring an SEIS: the court held that

the new listing changed the legal status of the salmon, but it did not change the biological status. The Forest Service previously determined that it was un likely that the proposed actions would have a negative impact on the salmon; as this finding was not premised on the salmon’s non-threatened status, the determination that the salmon were in fact threatened did not constitute new information. 148

Here, the CERCLA designation itself is not significant; it is a change in the Bay’s legal status, but not its environmental characteristics. The Corps’ previous findings regarding the impacts of dredging in the Bay are not disturbed by this change in status. However, the fact that the Corps’ dredging will take place alongside an RI/FS is a real, physical change, that may alter the environmental impact of dredging. Whether this change is a significant one is an empirical and scientific question, which requires adequate consideration by the Army Corps. 149

More fundamentally, the Army Corps’ argument is contrary to the standard of review prescribed by Marsh and Grand View. 150 It is the initial responsibility of the agency, not the Court, to determine whether new information or circumstances are sufficiently significant to warrant an SEIS. Under Grand View, the Court’s role is to determine whether the agency took a sufficiently “hard look” at the significance of new circumstances, and, if so, whether its decision that they were not significant was arbitrary or capricious. An agency violates NEPA when it fails to give adequate and timely consideration to the significance of new circumstances, regardless of whether it is able, during the ensuing litigation, to provide evidence that the new circumstances are not significant. 151 The threshold question, therefore, is not whether the new circumstances were significant, but whether the Army Corps took a sufficiently hard look at the significance of those new circumstances. 152

2. The Army Corps Failed to Comply with NEPA Because It Did Not Take the Required Hard Look

a. The Army Corps’ Subsequent Decision to Prepare an EA Is Not a Concession That Its Prior Review Was Inadequate

At the outset, plaintiffs’ argument that the Corps’ decision to prepare an EA 153 is a concession that its previous environmental review was inadequate is without merit. The Corps has never conceded that it is required to prepare an SEIS, although it has suggested that it would consider the possibility. 154 In fact, the Corps has suggested that the purpose of the EA is to “document why no SEIS is necessary.” 155 This is somewhat disturbing. The purpose of an EA is not to document a foregone conclusion, but, pursuant to the Corps’ regulations, to “provide[] sufficient information to the district commander ... for determining whether to prepare an SEIS or a FONSI.” 156 “[A]n agency’s NEPA analysis ‘must be taken objectively and in good faith ... and not as a subterfuge designed to rationalize a decision already made.’ ” 157 Nevertheless, the question before the Court is whether the Corps’ review of the issue prior to December 29, 2004 and March 11, 2005 was reasoned and adequate; the quality of the Corps’ subsequent documentation is irrelevant. 158

b. The Prior Environmental Reviews Conducted by the Corps Are Sufficient to Address Certain Issues

Although the analysis the Corps engaged in between October and December 2004 was brief and informal, it built on decades of prior environmental review. Plaintiffs challenge that review on the ground that the Corps failed — as far as the record shows — to consider the results of its own 2003 report, “SSFATE [Suspended Sediment FATE] Modeling of Arthur Kill Dredging.” 159 This report used a new model to derive predictions regarding the effects of dredging which differed significantly from those of the reports on which the 1999 FEIS relied. Notably, the 1999 FEIS concluded that resuspended sediments would travel no further than 500 feet from the dredge; the SSFATE Report predicts that resuspended sediments will travel up to two miles. 160 The Corps’ January 2004 EA/LRR addressed the SSFATE Report, albeit only in the context of the impact of dredging on fish habitats. The failure to give greater consideration to the SSFATE Report, though questionable, does not by itself demonstrate that the Corps failed to take the requisite “hard look.” “NEPA does not require that [the Court] decide whether [a finding of no significant impact] is based on the best scientific methodology available.” 161 The Corps’ analysis of sediment resuspension was based on adequate scientific data. 162

Accordingly, the Corps’ determination, in its December 16, 2004 memorandum and its February 28, 2005 Statement of Findings, that the designation of the Bay as a CERCLA Study Area, by itself, did not require additional NEPA documentation, is beyond reproach. Plaintiffs suggest that the AOC signaled a new public policy in favor of cleaning the Bay, requiring the Corps to revisit the entirety of its prior analysis of the environmental impacts of dredging. However, even if CERCLA designation represents a shift in public policy, it is irrelevant to the Corps’ NEPA obligations: as in Swanson, a shift in public policy, by itself, is not an environmental change that requires additional NEPA review. The Corps’ extensive prior environmental reviews sufficiently analyzed the environmental impacts of dredging in the Bay, on, inter alia, water quality, 163 noise, odor and aesthetics, 164 geological stability, 165 exposure of biological receptors to contaminants, 166 and human health and safety, 167 and considered methods for minimizing those effects. This review has not been affected by the change in legal status of the Bay. Whether the HDP should proceed despite the change in the legal status of the Bay is a legal and policy determination rather than a scientific or empirical one, and the Corps’ brief dismissal of this issue was sufficient to constitute a hard look. 168

c. The Impact of the HDP on the RI/FS

The important question here, however, is not whether the mere fact of the AOC itself somehow called for additional NEPA review; the question is whether the HDP will have significant impacts on the RI/FS that will be conducted in the Bay-pursuant to the Feb. 2004 AOC. 169 As I have said, the fact that sampling for an RI/FS will be performed is a physical change in the activities that will take place in the Bay, not just a change in legal status. When the Army Corps conducted its pre-February, 2004 environmental analysis, it did not know that Tierra would be carrying out sampling studies for an RI/FS in the Bay. The presence of Tierra’s sampling activities in the Bay is a physical change. This sampling is likely to be essential for the effectiveness of the EPA’s cleanup of the Bay (or to determine whether such a cleanup is feasible). Dredging may significantly disrupt or frustrate Tierra’s activities, and therefore delay or prevent a cleanup of the Bay. The Corps’ prior review of dredging methods and the direct environmental effects of resuspension due to dredging does not address the issue of whether dredging will interfere with sampling.

i. Pre-December 29, 2004

The Corps’ pre-December 29, 2004 consideration of the possible effects of dredging on the RI/FS was inadequate. Many of the documents on which the Corps relies — specifically, the email communications between the EPA and the Corps prior to October, 2004, attempting to arrange a meeting between EPA and Corps officials to discuss the impact of the AOC — are without substance. 170 The Corps’ substantive consideration of the issue began in October 2004 at the earliest. The record establishes that the Army Corps, despite its efforts to review its dredging methods and re-examine its prior environmental analysis, failed to give serious consideration to the potential impacts of dredging on sampling for the RI/FS, or the means by which those impacts could be minimized, before awarding the Arthur Kill dredging contract on December 29, 2004.

The Corps’ determination that dredging would have no significant impact on the RI/FS was based almost entirely on the EPA’s statements, as recorded in the Corps’ internal documents. First, a December 1, 2004 memo records that the EPA informed the Corps that “whether Newark Bay is designated a Superfund Site will not prevent all activity, such as harbor deepening.” Clearly, a statement that dredging need not halt altogether is not the same as a statement that dredging will not have significant impacts on the RI/FS.

The Corps’ record of the December -6, 2004 meeting with the EPA states that the EPA informed the Corps that “based on existing information and ongoing coordination, the dredging planned for the HDP in Newark Bay would not delay or prevent an effective cleanup.” 171 Such “[sjimple, conclusory statements of ‘no impact’ are not enough to fulfill an agency’s duty under NEPA.” 172 “[CJonclusory remarks ... do not equip a decisionmaker to make an informed decision about alternative courses of action or a court to review the [agency’s] reasoning.” 173

This conclusory statement is no more satisfactory because it originates outside the Army Corps, in an agency with relevant expertise. An agency is justified in relying on another agency’s finding of no significant impact where that agency’s finding is supported by reasoned analysis. 174 There is no indication in the record here that the EPA’s statement is supported by anything more than a hunch. 175

The Corps argues that there is “no practical reason why the Army Corps cannot reasonably rely upon EPA’s informal statements.” 176 This argument misses the point: there is no reason why a conclusory statement that would not pass muster under NEPA if made by the Army Corps itself should be found sufficient simply because it originated with an outside entity. To hold otherwise would render NEPA toothless. The fact that the EPA possesses special expertise in this matter makes no difference. The expertise and analysis underlying the agency’s findings must be apparent from the record. That is not the case here.

The Corps’ finding that dredging will not interfere with the RI/FS also relies heavily on the promise of future coordination between the Corps and the EPA. The Second Circuit has held that “[w]hen the adequacy of proposed mitigation measures is supported by substantial evidence, the agency may use those measures as a mechanism to reduce environmental impacts below the level of significance that would require an [S]EIS.” 177 The Court has no reason to doubt the Corps’ good-faith intention to coordinate with the EPA. The record shows, for example, that the Corps and the EPA have communicated regarding the Corps’ dredging schedule. 178 However, the record does not contain any substantive discussion of the form this coordination will take, or how the effectiveness of that coordination will be monitored. The Corps’ “Construction Monitoring and Management Plan,” discussed in the 1999 FEIS, is of course silent on the issue of the impact of dredging on the RI/FS, which was not planned until 2004. 179 The Corps’ ongoing monitoring obligations under the WQCs, though substantial, also do not address this specific issue. NEPA requires that the Corps give these issues timely and public consideration. 180

The Corps’ December 16, 2004 memorandum contains no further analysis of the impact of dredging on the RI/FS. 181 The memorandum simply relies on the fact that “no substantial changes in the physical or chemical nature of [the Bay’s] sediments in the project occurred as a result of the AOC.” 182 For the reasons given above, this statement, while true, misses the point. The signing of the AOC was — of course — a mere legal change, which did not affect the physical character of the Bay. The point is that, pursuant to the AOC, an RI/FS will take place in the Bay, something that was not true before the AOC. The Corps’ dredging activities may have significant impacts on the RI/FS, and thus on the environment. That issue — an empirical and scientific question' — should have been explored properly, but was consistently overlooked. I therefore find that the Corps failed to take a hard look at the significance of the AOC before December 29, 2004, and was in violation of NEPA and the APA with respect to the AK 41/40 Project.

ii. Pre-March 11, 2005

Between December 29, 2004 and March 11, 2005, the Corps prepared a draft Statement of Findings, and produced a number of declarations in opposition to plaintiffs’ motion for a preliminary injunction. The Statement of Findings contains no further analysis of the possible impact of dredging on the RI/FS. The Statement merely repeats the Corps’ prior determinations that the February 2004 designation of the Bay as a CERCLA Study in itself does not require NEPA documentation, that dredging need not entirely halt for the RI/FS to take place, and that the EPA will coordinate its activities with the Corps. 183 The Declaration of George Pavlou, as noted above, is simply too conclusory to constitute the requisite “hard look.” The Declaration of Robert Engler contains a detailed rebuttal of plaintiffs’ contention that “dredging as currently proposed under the Project will resuspend and redistribute unacceptable amounts of contaminated sediments into Newark Bay.” 184 The basis for Dr. Engler’s conclusory statement that “the Project, as currently proposed, will not negatively impact the [EPA’s] RI/FS,” however, is entirely unclear from the record. 185 I therefore find that the Corps had not taken a sufficiently “hard look” at the impact of dredging on the RI/FS by March 11, 2005, and was in violation of NEPA and the APA with respect to the decision to begin the 50 foot HDP.

The Corps failed to take a hard look at the possible effects of dredging on the RI/FS before December 29, 2004 or March 11, 2005. Plaintiffs, for their part, have submitted expert testimony that raises a substantial possibility that dredging will have significant effects on the RI/FS. “A party challenging the agency’s decision not to prepare a supplemental EIS must show only that there is a substantial possibility that the action may have significant new impacts, not that it clearly will have such impacts.” 186 On the basis of the present, deficient record, it was arbitrary and capricious for the Corps to decide that it was not required to prepare an SEIS to consider the effects of dredging on the RI/FS. 187

Although plaintiffs have brought very narrow claims, the language of their Complaint and motion papers suggests that they have very broad objections to the Corps’ project. It is therefore important to stress the narrowness of today’s holding. I hold only that the Corps failed to take a hard look at the potential impacts of dredging on the RI/FS, and at methods of coordination with the EPA that might re duce those impacts, if any, and that the Corps’ decision to • proceed ' without an SEIS in the absence of such a hard look was arbitrary and capricious. I do not hold that the Corps’ review was inadequate with respect to any other issues raised by plaintiffs. Nor do I hold that the impact of dredging on the RI/FS will, in fact, be significant enough to' require the preparation of an SEIS. The Court has no competence to make that evaluation on the basis of the present record. 188 It is entirely possible that, once the Corps has taken the necessary ‘hard look’ at the issue, it will be justified in finding that no SEIS is required.

This Opinion addresses only the question of whether the Corps is in violation of NEPA and the APA. Further briefing will be required to address the issue of remedy. In particular, the parties should address the issue of whether the additional environmental review conducted by the Corps in the course of preparing its proposed EA is sufficient to moot plaintiffs’ demand for relief. 189

V. CONCLUSION

For the foregoing reasons, I find that the Corps’ December 29, 2004 decision to proceed with the AK 41/40 Project, and its March 11, 2005 decision to proceed with the HDP 50 foot Project, were made without a “hard look” at the environmental consequences, and were arbitrary and capricious, in violation of NEPA and the APA. The parties are to jointly propose a briefing schedule on the issue of remedy, no later than August 19, 2005. At the same time, the parties should submit letter briefs of no more than five pages addressing the issue of the extent of the record to be considered by the Court in determining the appropriate remedy. 190

132 . Although plaintiffs repeatedly criticize the project as a whole, claiming that dredging will result in unacceptable levels of resuspension of contaminated sediments, see, e.g., Plaintiffs' Memorandum of Law in Support of Motion for Summary Judgment at 19, 21, plaintiffs make it quite clear that the specific basis for their motion is the narrower claim that dredging will interfere with the RI/FS.

140 . Id. at 26.

141 .See supra Part II.A, pp. 7-10. The parties hotly dispute the extent to which the AOC commits the EPA to conduct such a clean-up. The Army Corps contends that a clean-up is only a possibility. Despite plaintiffs’ claims that some remedy is inevitable, the AOC itself states that one of the "alternative remedial actions” the EPA will consider at the conclusion of the RI/FS is "[a] no action alternative.” Feb.2004 AOC Statement of Work at 3, AR 48:16154. However, although it is not certain that the EPA will clean up the Bay, NEPA requires consideration of "reasonably foreseeable” effects, not just certain ones. See Mid States Coalition for Progress v. Surface Transp. Bd„ 345 F.3d 520, 549 (8th Cir.2003) ("an environmental effect is 'reasonably foreseeable' if it is sufficiently likely to occur that a person of ordinary prudence would take it into account in reaching a decision.”) (quoting Siena Club v. Marsh, 976 F.2d 763, 767 (1st Cir.1992)). There can be no serious doubt that some remedial action is sufficiently likely to occur that the possibility must be taken into consideration.

149 . The Corps' argument that "plaintiffs have adduced nothing more than conclusory allegations and speculation to support their contention” that dredging may interfere with the RI/FS is misplaced. Army Corps Mem. at 27. First, plaintiffs have submitted expert analysis to support their argument: it is 'speculative' only in the sense that it deals with possible future events. Second, it is the Corps’ duty to evaluate the significance of the new circumstances, not plaintiffs’.

150 . See Marsh, 490 U.S. at 376, 109 S.Ct. 1851; Grand View, 947 F.2d at 657.

151 . See Marsh, 490 U.S. at 385, 109 S.Ct. 1851 ("Regardless of its eventual assessment of the significance of this information, the Corps had a duty to take a hard look at the proffered evidence.”); Friends of the Clear-water, 222 F.3d at 558 ("Although the Forest Service now can point to data that, if timely considered, would have shown that the new information did not require an SEIS, this does not demonstrate that the Forest Service complied with NEPA, which demands timely and reasoned agency action.”); NRDC v. Lujan, 768 F.Supp. 870, 889 (D.D.C.1991) ("A court's role in reviewing a decision not to supplement an EIS involves carefully reviewing the record and satisfying [itself] that the agency has made a reasoned decision based on its evaluation of the significance — or lack of significance — of the new information.... Affidavits such as those presented here are no substitute for an explanation in the [record] itself that environmental impacts were considered and determined to be significant or not.”) (quotation omitted).

152 .The Army Corps argues that this standard — which it calls "a 'one-step' inquiry whereby a plaintiff need only prove that the agency failed to take a ‘hard look’ at purported information, regardless of its significance” — may result in courts finding “violations of NEPA even where the new information is patently insignificant.” Army Corps Reply Memorandum in Support of Motion for Summary Judgment ("Army Corps Reply Mem.”) at 2. While this risk may exist, NEPA is a procedural statute, and requires compliance with its procedures at the proper time; failure to comply with those procedures cannot be excused in hindsight. As a practical matter, though, the Army Corps’ concern is overstated, for two reasons. First, under Marsh, courts must apply a "rule of reason” to their re view of the sufficiency of the agency's decision-making; in addition, Marsh makes clear that courts need only ask whether an agency's decision was based on "consideration of the relevant factors.” Marsh, 490 U.S. at 375, 378, 109 S.Ct. 1851. If new information is truly patently insignificant, an agency may be able to meet its obligations under NEPA with only the most cursory look at its significance, and if it is simply irrelevant, the agency need give it no consideration. Second, if the agency is able, during litigation, to demonstrate that information that it failed to consider in a timely manner is in fact insignificant, that may be considered when determining whether any injunctive relief is required. See, e.g., Friends of the Clearwater, 222 F.3d at 560. In any case, for the reasons discussed above, the concerns raised by plaintiffs here cannot be described as irrelevant or patently insignificant; plaintiffs’ concerns were clearly sufficiently substantial to deserve proper consideration.

158 . To hold otherwise would create a perverse incentive, discouraging federal agencies from voluntarily conducting any supplemental environmental review in response to a plaintiff’s demands, for fear of being found to have conceded a violation of NEPA.

In Laguna, the Federal Highway Administration (FHA) properly relied on consultation with other federal agencies to determine that a forest fire had not given rise to significant new circumstances requiring an SEIS. The FHA's consultation with one agency resulted in a new Biological Opinion. The second agency, the Army Corps, submitted a written report to the FHA, prepared by its biological experts.

175 . The Army Corps argues that Pavlou’s February 28, 2005 Declaration sets out the basis for the EPA’s December 6, 2004 statements. Even if this is true, Pavlou's declaration is scarcely less conclusory. Pavlou states that "dredging will not dimmish the usefulness of the RI/FS” because the RI/FS must, in any case, “account!] for” the "current and existing conditions in Newark Bay,” which include vessel traffic and other ongoing maintenance dredging. Pavlou Deck ¶ 11, AR 48:16273. Pavlou's declaration provides no analysis of the relative impacts of the HDP and those other sources of disturbance. Nor does Pavlou discuss measures the Corps may take to reduce the impact of dredging, or to help the EPA to ‘account for’ the Corps’ activities.

180 . Plaintiffs’ expert suggests a number of ways in which the Corps should coordinate its activities with the RI/FS, including: "by sampling before and after Deepening activities occur (to measure changes) ... by pinning down where redistributed (contaminated) sediment is settling and then sampling in those locations, and by timing the dredging and blasting so that those activities do not render obsolete Superfund samples taken previously in the same areas.” Livingstone Deck ¶ 24. Of course, NEPA does not require that the Corps actually adopt any of these measures.

181 . In preparing the December 16 Memorandum, the Corps re-reviewed the dredging methods used in the Hudson River Superfund Site, in which "limited navigational dredging” will take place alongside a Superfund cleanup (as opposed to an RI/FS). See December 14, 2004 Memorandum to Record, "Comparison of Hudson River PCBs Cleanup and N.Y. Harbor 50,” AR 2:274-79. This review gives serious consideration to the appropriate dredging and resuspension control technologies for Newark Bay, in order to reduce resuspension’s direct effect on the environment. However, it does not touch on the key issues of the potential impact of dredging on sampling to be conducted for the RI/FS, or on methods of coordination that might minimize that impact. In fact, the discussion states that in Newark Bay, "resuspension is a concern” only because "it may bury benthic [i.e., bottom-dwelling] organisms.” AR 2:275.

182 .Dec. 16 Mem., AR 2:262.

183 . The only new substantive discussion in the Statement of Findings appears in the "Draft 2005 NRDC NOI Response Table,” where the Corps argues that "since the material to be removed by the HDP dredging is tested prior to its removal to determine its placement options and these test results are provided to the state regulatory agencies for their use in issuing Water Quality Certificates, the District is confident that the material being removed will not impact the results of the FS/RI or any potential remedial action.” AR 1:189.

At oral argument, counsel for the BLM assured us that to the eye of the 'agency specialists,’ the scant information included in the EAs is sufficient to determine what the cumulative environmental impacts will be and supports the conclusory statements that they will not be significant.
