I. INTRODUCTION

This opinion resolves the remedial phase of litigation stemming from the failure of the United States Army Corps of Engineers and Col. Richard J. Polo, Jr., as Commander and District Engineer of the Corps’ New York District, (collectively the “Corps”), to take a “hard look” under the National Environmental Policy Act (“NEPA”) 1 at the consequences of a project to deepen shipping channels in the New York-New Jersey Harbor (“Harbor”) through dredging and blasting of the Harbor floor. 2 Plaintiffs, a group of environmental organizations and concerned citizens, claimed that the Corps violated NEPA by not considering the impact of the Corps’ Harbor Deepening Project (“HDP”) on the United States Environmental Protection Agency’s (“EPA”) plan to study decades of industrial pollution and evaluate possible cleanup options for contamination in the Harbor. In an earlier opinion, I found that the Corps had violated both NEPA and the Administrative Procedures Act (“APA”). 3 Plaintiffs now request that the Court order the Corps to prepare NEPA-compliant documentation pursuant to a schedule, with specific instructions on the elements and process, for completing the documentation. Plaintiffs also request an injunction prohibiting future contracting in connection with the HDP until such time as the Court approves the Corps’ final NEPA documentation. 4

II. BACKGROUND

The facts underlying this case are comprehensively set out in my Opinion and Order of August 5, 2005 (“August 5 Opinion”). 5 Briefly, the HDP is intended to open the Harbor to the newer, larger, and deeper-bottomed cargo vessels on which the modern shipping industry depends. As part of the HDP, the Corps has been authorized to conduct the Kill Van Kull 45' Deepening Project, the Arthur Kill 41/40' Deepening Project, the Port Jersey 41' Deepening Project, and the 50' New York and New Jersey Harbor Deepening Project. 6 In 2002, Congress ordered the Army Corps to consolidate each of these projects into one overall deepening project, known as the HDP. 7

Part of the HDP will cut through highly contaminated sections of Newark Bay and surrounding waterways. This contamination is the result of years of heavy industrial use of the Bay and its tributaries. In particular, the Bay is contaminated with the by-products from the manufacturing of Agent Orange at the Diamond Alkali Chemical Plant, 8 on the Passaic River, during the Vietnam War.

On February 13, 2004, the EPA entered into an AOC, which added Newark Bay to the Diamond Alkali Superfund Site, as the “Newark Bay Study Area of the Diamond Alkali Superfund Site” pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (“CERC-LA”). 9 Under the direction of the EPA, Tierra Solutions, Inc. (“Tierra”) is carrying out a Remedial Investigation/Feasibility Study (“RI/FS”) on behalf of Occidental Chemical Corporation, successor to Diamond Shamrock Chemicals Company, pursuant to the terms of the AOC. The RI will determine the extent and nature of contamination in the Bay, and the FS will evaluate possible cleanup options based on what is learned from the RI. 10 This process also contemplates the preparation of a Natural Resources Damages Assessment for the Diamond Alkali Superfund Site, in which natural resources trustees (the National Oceanic and Atmospheric Administration, the U.S. Fish and Wildlife Service, and the New Jersey Department of Environmental Protection) will determine the injury to the natural resources, establish a plan for restoration of the natural resources, and determine compensation to the public for loss of services from the resources. 11

A. August 5 Opinion

Plaintiffs claimed that the Corps acted arbitrarily and capriciously, in violation of NEPA and the 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 August 5 Opinion granted summary judgment to plaintiffs, holding that the “Corps failed to take a hard look at the potential impacts of dredging in the HDP on the RI and at methods of coordination with the EPA that might reduce 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.” 12 I found the Corps’ NEPA review deficient for the following reasons:

• The Corps “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.” 13

• “[T]he record did not contain any substantive discussion of the form coordination between the EPA and the Corps will take, or how the effectiveness of that coordination would be monitored.” 14

• The Corps did not do any “further analysis of the possible impact of dredging on the RI/FS” before March 11, 2005 when the Corps awarded the first contract for dredging in the Kill van Kull Channel. 15

Based on these findings, I concluded that “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 the sampling and causes unrecoverable delays to the potential cleanup process.” 16 Finally, I ordered the Corps to “give full consideration to how cooperation between the EPA and the Corps can minimize the effects of dredging on the RI/FS before committing to a particular method of dredging, not after problems arise.” 17

By agreement of the parties, I bifurcated the issues of liability and remedy. 18 Having found liability, I now address the appropriate remedy.

B. Record Under Review During the Liability Phase

Beginning in 1980, the Corps produced over a dozen separate NEPA documents on the HDP. In December 1999, the Corps prepared a Final Environmental Impact Statement (“1999 FEIS”) to “identify, screen, evaluate and recommend a plan for channel improvements throughout the Port of New York and New Jersey.” 19 In January 2004, the Corps assessed any changes to the project due to the consolidation of the dredging contracts into the HDP and produced a Limited Reevaluation Report and Environmental Assessment (“2004 EA”) that resulted in a Finding of No Significant Impact (“FONSI”). 20

The August 5 Opinion considered only the limited “administrative record compiled by [the Corps] when it made the decision” under review. 21 In an order dated May 9, 2005, I found that the Corps made two decisions that were relevant to a review of its NEPA compliance. On December 29, 2004, the Army Corps awarded a contract with respect to the Arthur Kill 40/41 project without preparing an SEIS. On March 11, 2005, the Corps awarded a contract for the S-KVK-2 project in the Kill van Kull Channel, a project which the Corps concedes is part of the HDP, again without reviewing the designation of the Newark Bay as a Study Area (“NBSA”) and the impact of the dredging on the RI/FS. The Corps’ NEPA documentation as of those dates, including the 2004 EA and the 1999 FEIS, was submitted to the Court for consideration in the liability phase.

C. The Remedy Phase

During the pendency of this action, the Corps began to evaluate the potential impacts of the deepening projects on the RI/FS in the form of a Draft Environmental Assessment on the Newark Bay Area of the New York and New Jersey Harbor Deepening Project (“Draft EA”). The Draft EA was published in June of 2005. 22 It found that the designation of Newark Bay as a CERCLA Study Area did not alter the “existing characterization of resources in the study area or the proposed dredging plans and therefore [had] no effect on the previous analysis of impacts presented in the 1999 [FEIS] or the 2004 EA.” 23 The Draft EA also relied on promises of coordination between the Army Corps and the EPA to ensure that no significant impacts to the RI/FS would occur as a result of the dredging or on the HDP as a result of the RI/FS. 24

In September 2005, after this Court’s liability ruling, the Corps announced that it intended to publish an Amendment to the Draft EA (“Draft Amendment”) to further evaluate the impacts of the HDP on the RI/FS and the “methods of coordination with EPA that might reduce those impacts.” 25 Because the sampling plans and the HDP are both time-sensitive, the Court ordered immediate briefing of the remedy issue once the Draft Amendment was published.

The Draft Amendment was published on September 30, 2005 and was intended to provide a qualitative and quantitative analysis of the potential effects of the Corps’ dredging activities on the NBSA Remedial Investigation Work Plan (“RIWP”). 26 The Draft Amendment also set out a coordination plan, intended to help the EPA and Corps avoid, minimize, and/or mitigate any possible effects of the dredging on the sampling work and ensure that the goals of the RI/FS are met. 27

In October 2005, plaintiffs sought injunc-tive relief, arguing that the Corps had not cured the NEPA violations found by the Court. I held a hearing on December 8, 2005, at which time the Corps promised to publish the Final EA by December 31, 2005. Based on that representation, I postponed consideration of the appropriate remedy until after the Final EA was published and the parties had an opportunity to address its adequacy. On January 6, 2006, 28 the Corps published the Final EA and Final Amendment to the EA (collectively the “EA”). 29 The EA concludes that “the effects of dredging on the ability of [the] USEPA to achieve the RIWP study goals are determined to be insignificant and to have no material bearing on EPA’s decision-making process regarding potential remedies.” 30 The EA again recommends a FONSI for the dredging projects, thus making the preparation of an SEIS unnecessary. 31

On January 27, 2006, plaintiffs renewed their request for injunctive relief and filed a supplemental memorandum of law. The Corps also filed a supplemental memorandum of law in opposition to plaintiffs’ request. Both parties addressed the portions of the Final EA and the Final Amendment to the EA that were revised from the draft versions.

For purposes of the remedy phase, a court is not limited to the administrative record. 32 Evidence falling outside the administrative record is relevant to whether relief should be granted if such evidence shows “that an agency has rectified a NEPA violation after the onset of legal proceedings.” 33 Thus, the parties agreed to submit to the Court all materials concerning the Corps’ NEPA compliance that were before the agency between the close of the administrative record and the date of the Final EA. This included, inter alia, the RIWP, multiple emails between the Corps and the EPA, sampling schedules, memoranda of record on coordination meetings, public comment received by the Corps in response to the Draft EA and the Draft Amendment, the Corps’ Draft EA, Amendment to the Draft EA, and the Final EA. These documents were fully submitted, with supplements, 34 by February 17, 2006.

D. The NBSA RIWP and Ongoing Deepening Projects

In September 2005, Tierra published “revision 1” of the RIWP, laying out goals and objectives for the EPA’s study. 35 An essential component of the study will be to perform sampling on surface sediment, subsurface sediment, and water in the Bay to determine the distribution and concentration of contamination. The study will also help develop a historical record of sediment deposition, as any record of sediment deposition which may have existed has been modified or eliminated by substantial dredging activities in the past. 36 Under the current plan, the RI has three goals:

• RI Goal 1: Determine the horizontal and vertical distribution and concentration of [chemicals of potential concern (“COPCs”) 37 ] for the Newark Bay Study Area sediments.

• RI Goal 2: Determine the primary human and ecological receptors ... of [COPC] contaminated sediments in the Newark Bay Study Area.

• RI Goal 3: Determine the significant direct and indirect continuing sources of the [COPCs] to the sediments in the Newark Bay Study Area. 38

A phased sediment investigation sampling program is planned to address the first goal. The primary objectives of this first phase of sampling are to:

• support further development of the preliminary conceptual site model and verify that the geomorphic areas used for sampling are appropriate for future programs;

• estimate the approximate depth of a critical ‘horizon’ in the sediment bed

• better understand broad patterns of constituents in both the surface and subsurface sediments, and attempt to preliminarily identify ‘hot spots’ through statistical analyses; and

• confirm that the current analytical chemistry and radiochemistry suite is appropriate for future testing; and

• determine data needs for Phase II. 39

Sampling under the first phase of this sediment investigation began on October 24, 2005. 40

In addition, deepening projects in the Arthur Kill and Kill van Kull contract areas are currently either underway or already complete. The Corps awarded the first contract for dredging in the Arthur Kill Channel on December 29, 2004. 41 It has since proceeded with the Kill Van Kull 45’ deepening project. 42 In August 2005, the Corps began to coordinate its dredging activities with EPA’s sampling plans in areas affected by these two projects. As a result of consultations with the EPA, the Malcolm Pimie consultants, and the technical project managers to the EPA on the Newark Bay Study, the Corps concluded that the deepening projects would not affect the initial sampling that the EPA planned for the fall of 2005. 43 The Corps and the EPA have since held regular monthly meetings. 44

E. The January 2006 Pinal Environmental Assessment

There are several aspects of the EA worth describing in some detail. These include the EA’s assessment of the potential impacts of the HDP on the RI/FS, analysis of the cumulative impact of the dredging, alternatives analysis, and coordination and monitoring provisions.

1. Assessment of the Potential Impacts of the HDP on the RI/FS

The Corps concludes that the dredging will not have significant impacts on the RI/FS sampling. 45 The Corps’ discussion is divided into three geographical regions: (1) navigational channels, (2) port channels, and (3) areas adjacent to the dredged areas, including tidal flats. The discussion regarding the navigational channels and port channels explains that while dredging is slated to occur in the same area as sampling, dredging will not adversely affect sampling in those regions. The discussion regarding “areas adjacent to the dredged areas” assumes that most dredging will not occur in the areas outside the channels but that resuspended sediments may be redeposited outside the dredged areas, making it necessary to conduct a quantitative analysis of this resuspension. 46

The EA begins by discussing the effect of dredging on surface and subsurface samples in the navigational and port channels. The EPA plans on taking three subsurface samples for each of the coring locations in the navigational and port channels. 47 In its discussion regarding this subsurface sampling, the EA assumes that the samples will be taken to “evaluate historical deposition” and concludes that dredging will not affect the EPA’s ability to “collect historical data.” 48 The EA explains its conclusion by pointing to the RIWP’s comment that “the [informational] value of vertical segments [in the navigational channels] is expected to be relatively low,” thus intimating that the EPA will not rely on those cores. 49 The EA notes that the EPA will instead rely on “data collected in the flats” for its historical analysis and avoids the simple question of whether dredging will affect any other uses of the subsurface sampling in the navigational and port channels. 50 Notably, a certain amount of dredging will occur outside the channels, in the tidal flats, “as part of the channel widening that is anticipated in the HDP.” 51 The EA’s discussion does not address whether dredging in those areas will affect EPA’s ability to collect historical data or whether it will affect the interpretation of data already collected from the tidal flats.

For surface samples being taken in the navigational and port channels, the EA focuses on samples taken before the HDP dredging and again concludes that the utility of these samples will not be affected by that dredging. 52 The EA states that the samples will be taken in a dynamic portion of the channel which has been subject to dredging and multiple disturbances from ships and storms over the years. Thus, these samples will represent a record of “material deposited since the previous dredging event, in some combination with material left after the last dredging event.” 53 If the sediment is dredged again as part of the HDP, the EA notes that the samples taken before the HDP dredging will remain useful because they will “represent the contaminant data of recently settled material.” 54 The EA also finds that removal of sediment will not affect the utility of surface samples; but if it does, more samples can be taken in other areas, such as recently dredged areas. 55

The EA next assesses the effect of dredging on samples taken in areas “adjacent to the dredged areas.” 56 As the Corps noted, dredging in the channels may “indirectly affect the interpretation of the data from ... sediment cores [taken in areas adjacent to the channels] by causing contaminated sediments from the channels to be resuspended and deposited onto the sediment surfaces in areas where such cores will be taken.” 57 In order to make this assessment, the Corps analyzed the effect of resuspension on contaminant concentrations. The Corps asserted that it studied the “(1) the amount and spatial extent of sediments that are resuspended from channels by dredging, (2) the concentrations of contaminants of those resus-pended sediments and (3) the resulting effect on the chemical analyses performed on the Phase I sediment cores taken from adjacent areas.” 58 For this discussion, the EA relies on: (1) two resuspension studies it conducted in 2001 and 2005; 59 (2) sediment data from several studies of contaminant concentrations in resuspended material in the Bay; 60 and (3) the analysis of 104 cores which were collected during recent dredging in the NBSA and assessed for the presence of 2,3,7,8-tetrachlorodi-benzo-p-dioxin (“TCDD”). 61

The EA focuses on whether dredging and resuspension would increase the concentration of contaminants in the surface sediments. The EA compares the concentration of contaminants measured beneath the surface with that of contaminants on the surface. 62 It uses average concentrations from each dredging contract area to make this comparison. 63 The EA relies on cores that were collected “from depths required to fully capture the silt material that will be removed from dredging.” 64

After calculating these averages, the EA assesses the potential increase in surface level contamination from dredging. For Newark Bay and Kill van Kull the Corps found that “average concentration of contaminants measured ... were similar to or less than concentrations in ' the surface sediments, indicating that resuspended dredged material will not likely increase surface sediment contaminant concentrations.” 65 For Arthur Kill, average concentrations of TCDD “were similar to concentrations in the surface sediments,” however, “[a]verage concentrations of the other compounds in Arthur Kill composite cores were greater than the overall aver ages for surface sediments.” 66

Because of the greater contaminant levels in the Arthur Kill cores, the EA analy-ses the effects of dredging on depositions in the Arthur Kill flats. The analysis concludes that any increase in surface level contamination would be negligible and would not affect the sampling. For example, it notes that “the contaminant concentrations in 6 in. surface sediment core segments would be increased by no more than 5% for all chemicals due to the dredging of Arthur Kill sediments.” 67

Of special note here is the EA’s reliance on averaging. The EA states that “it is possible that local variation in contaminant concentrations and in the dynamics of re-suspension and circulation may cause local variation in effects of the dredging on surface sediments.” 68 To assess whether that calls into question its use of averaging, the Corps looked at a limited number of core samples for the presence of TCDD. It compared the concentration of TCDD in the cores with an elevated concentration to other cores in the vicinity. The Corps found that the cores in the near vicinity to the cores with an elevated concentration did not exhibit high levels of contaminants. 69 Thus, it appeared that elevated concentrations were of “limited spatial extent,” that the surface concentration of TCDD would be “unlikely to change” due to resuspension, and that the use of averaging was appropriate. 70 The EA con-eludes that (1) the effects of resuspension from dredging in areas where there may be an elevated concentration of contaminants will be limited, and (2) that this analysis is “relevant to the rest of the EA.” 71 However, the Corps notes that “as additional data becomes available this issue will be reevaluated.” 72

In conclusion, the EA finds that for Goal 1 of the RIWP (1) the deepening project will have no significant effects when it is conducted after sampling of cores in the channels or in the areas adjacent to the channels, (2) dredging during sampling in both these locations will have no significant effect on the samples and any impacts will be mitigated by the coordination plan, (3) dredging in the channels prior to sampling will have no significant impact on the sampling, but the coordination plan and efforts to identify alternative sampling locations where needed will mitigate any effects, and (4) dredging prior to sampling in the areas adjacent to the channels will have no significant effect. 73 The EA also concludes that no combination of dredging before or after sampling in channels or in the areas adjacent to the channels will have significant effects on Goals 2 and 3 of the RIWP.

2. Cumulative Impact

The EA concludes that the cumulative effects of operation and maintenance dredging will likely be insignificant, but that coordination between the Corps and the EPA'is planned “to ensure that each' agency’s program goals are not adversely affected.” 74 In reaching this conclusion, the EA notes that currently only three sampling locations are “within areas potentially planned for federal maintenance-dredging,” and, because the dredging will not occur until May 2006, it will not affect those samples. 75 The EA also notes that in the future “sampling and testing will be performed prior to every episode of 'federal maintenance . dredging.” 76 The Corps will use these tests “to determine whether the sediments will adversely affect the RI/ FS” and' share the information with the EPA. 77

3. Alternatives

The EA contains two discussions of alternatives to the HDP. First, in a section called “environmental effects and consequences” the EA summarily notes that the Corps considered the consequences of the “no action alternative” in its 1999 FEIS. 78 The EA notes that the consequences of this alternative — namely maintaining the status - quo — were “primarily related to cost” and that the “no action impacts were determined to be potentially more damaging to the environment as resuspension of potentially contaminated sediments due to man-made causes ... and natural storm' events would occur at more intense and greater frequencies as compared to constructing the Recommended Plan.” 79

Second, the EA focuses on certain dredging best management practices, which were • proposed by the public and. plaintiffs as. methods for reducing the-amount of resuspension of sedipient and. contaminants during dredging, 80 The-analysis of best management practices began as a discussion of ways to “minimize'the potential for adverse environmental impacts from dredging.” 81 • In the Draft EA, best management practices ■ were contained in an appendix and noted in an’ “errata sheet” attached to the'-' Draft ■ Amendment. 82 • In the Final EA, the best management practices section-was- enlarged-to include more options and relabeled as “best management prac-. tices — alternative analysis.” The commentary formerly found in the errata sheet was moved to an appendix to the EA.

The analysis begins with certain protocols- which had been already addressed: the use of an environmental bucket (a lightweight bucket, without teeth, that' has a-variety of-.flaps to keep , the sediment from flowing back into the water during' hoisting), an environmental bucket in Historic Area Remediation Site (“HARS”)-suitable clay, 83 silt fences and turbidity curtains, cofferdams, air barriers, and blasting standards. 84 The appendix to the Final EA also includes several new dredging protocols: positioning software and sensors, rinse tanks, bucket speed restrictions, restrictions on hydraulic dredges, turbidity monitoring and performance standards, barge overflow standards, and adaptive management.

In addition, the EA notes that the Corps has already implemented several of the suggested best management practices, such as the use of environmental buckets. 85 The Corps rejected certain practices, such as positioning software, but noted that some of them may merit further investigation. 86 The Corps concluded that the other alternative protocols suggested were “inappropriate for navigational dredging, or would unnecessarily increase the cost and time to complete the HDP with only a modest if any decrease in the already significant impacts on the RI/FS study goals.” 87 The Corps also promised, through the use of adaptive management, to modify its dredging contracts should monitoring and testing demonstrate that different methods need to be adopted. 88

4. Mitigation

a. Coordination

The EA provides for a “coordination plan” to “ensure that impacts on the EPA’s remedial investigation and feasibility study, and possible future environmental remediation, of the [NBSA] from dredging activities are identified, avoided, and minimized to the fullest extent possible.” 89 The two-page plan establishes a coordination team made up of the Corps, the EPA, the United States Coast Guard, the Natural Resources Damages Trustees (the United States Fish and Wildlife Service, National Marine Fisheries, the New Jersey Department of Environmental Protection, the New York State Department of Environmental Conservation), and the Port Authority of New York and New Jersey. 90 In an appendix, the EA identifies the names and titles of specific individual representatives who will participate in the coordination plan on behalf of each agency. 91

The plan is co-chaired by representatives of the Corps and of the EPA, Region 2. Goals are set and a monthly meeting is scheduled to be held at the offices of the Corps and the EPA on an alternating basis. Meetings may be cancelled by the co-chairpersons “if there is no need to share information.” 92 The plan establishes that during the meetings the team will (1) update each other on current and future activities in the NBSA, (2) share information on respective projects in the Area, and (3) “resolve outstanding issues.” 93 The EA notes that as of the date it was issued, several sampling locations had already been moved in order to avoid any interference from dredging operations. 94

Notably, the RIWP relies on promises of-coordination. For example, the RIWP explains that during the sampling Tierra will meet with the Corps to “decide if select core locations need to change due to ongoing dredging activities” in the navigational and port channels. 95 However, Tier-ra is not included in the EA’s Coordination Plan team. 96 Instead, a Tierra representative attends the coordination meetings on a sporadic basis and an EPA representative typically provides the sampling update. 97

Since the publication of the Draft Amendment, the Corps also added a “dispute resolution” section to the coordination plan. This section was adopted after plaintiffs’ original brief in this litigation noted the lack of any kind of dispute resolution mechanism. 98 The current plan provides for a tiered dispute resolution mechanism. Team members are first directed to resolve the dispute. 99 If they cannot resolve the dispute within seven days, “the issue will be raised to the agency supervisors of the team- members” with the dispute. 100 If unresolved, again within seven days, the dispute is referred to the New York and New Jersey Harbor Senior Partners (senior representatives of each agency). 101

The Corps relies on coordination to mitigate any impact that the HDP could have on some aspects of the RI/FS. First, as noted, it relies on coordination to mitigate any impacts of maintenance dredging on the sampling. 102 Second, tifie EA notes that “it is difficult to evaluate what effect [the HDP] dredging may have upon future [natural resource] damage assessment activities” because those determinations have not yet been made. 103 However the EA provides for “coordination with the natural resource trustees” so that the effects of dredging on the process will be “minimized to the fullest extent practicable.” 104 There is no provision for assessing or re viewing the effectiveness of this coordination.

b. Monitoring

The Corps does intend, however, to rely on a monitoring program to “evaluate the extent of resuspension of sediments caused by dredging” throughout the life of the HDP. 105 The resuspension monitoring will be implemented in several ways. First, a Corps Construction Field Office Inspector will monitor the dredging activities to ensure “quality assurance” and will require an “inspector’s form,” which contains the:

(1) date and time of inspection, (2) type of bucket, (3) flaps on environmental bucket intact and operable, (4) hoist speed, (5) no barge overflow (if appropriate), (6) placement of dredge material in barge, and (7) corrective action taken (if necessary). 106

A member of the Corps’ Planning Division will also conduct unannounced inspections with the same inspector’s form, on the dredge, from an alternate vessel, and from the shoreline. 107 Pursuant to water quality certification requirements, which is governed by the state of New Jersey, 108 the Corps is also required to submit a “dewa-tering form” to the state environmental agency on a weekly basis, regarding pumping and discharging of sediment. 109

In addition, the Corps will perform a Total Suspended Solids (“TSS”) Monitoring Program, to sample suspended sediments due to dredging activities. 110 The Corps notes that the Monitoring Program has been modified in response to plaintiffs’ comments to “employ [an optical backscat-ter sensor] in such a manner as to measure turbidity at multiple locations and capture temporal variation in plume structure, to conduct multiple surveys of the plume via [an acoustic Doppler current profiler,] and to use a sufficient water sample size to determine the relationship between turbidity and TSS measures.” 111 Through these mechanisms, the Corps will constantly monitor the resuspension of sediments caused by dredging and dredge plumes. 112

The Corps will rely on monitoring to coordinate certain phases of dredging with sampling. For example, water samples will likely be taken as part of the RI/FS. 113 The EA notes that monitoring data from the dredging will provide ' guidance on when to conduct the water sampling. 114 The Corps expects monitoring data to be helpful to both the Corps and the EPA’s RUFS. 115

III. APPLICABLE LAW

A. Ripeness

The ripeness requirement is designed “to prevent the courts, through avoidance of premature adjudication, from entangling themselves in abstract disagreements over, administrative policies.” 116 It also protects “the agencies from judicial interference until an administrative decision has been formalized and its effects felt in a concrete way by the challenging parties.” 117 A court must evaluate “the fitness of the issues for judicial decision and the hardship to the parties of withholding court consideration.” 118

The Supreme Court has noted that because NEPA is designed to guarantee a particular procedure rather than a particular result, “a person with standing who is injured by a failure to comply with the NEPA procedure may complain of that failure at the time the failure takes place, for the claim can never get riper.” 119 For example,

one living adjacent to the site for proposed construction of a federally licensed dam has standing to challenge the licensing agency’s failure to prepare an [EIS] even though he cannot establish with any certainty that the statement will cause the license to be withheld or altered, and even though the dam will not be completed for many years. 120

Thus, where the allegation is that an agency’s final NEPA documentation fails to comply with NEPA procedure, there is no doubt the agency’s determination is ripe for judicial review. 121

B. Mootness

The jurisdiction of a federal court is limited to cases and controversies. 122 Thus, a federal court lacks authority “to give opinions upon moot questions or abstract propositions, or to declare principles or rules of law which cannot affect the matter in issue in the case before it.” 123 “A case or controversy becomes moot either when the injury is healed and only prospective relief has been sought, or when it becomes impossible for the courts to redress the injury through the exercise of their remedial powers.” 124

“[I]t is not appropriate to order injunctive relief regarding a project if the agency corrects violations of NEPA or agency regulations prior to implementation of the project.” 125 Where evidence outside the agency’s record demonstrates that the NEPA violations were corrected, and an injunction would serve no remedial purpose, a court should not issue an injunction. 126

C. NEPA Requirements

1. EIS

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.’ ” 127 “NEPA ensures that important effects will not be overlooked or underestimated only to be discovered after resources have been committed or the die otherwise cast.” 128 Thus, NEPA requires federal agencies to prepare a detailed EIS for “major Federal actions significantly affecting the quality of the human environment ... 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.” 129

2. SEIS'

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.’ ” 130 An agency’s determination whether to prepare an SEIS in light of new information or circumstances is governed by a “rule of reason.” 131 “[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.” 132 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. 133 As with the decision to prepare an EIS, “[e]lose calls should be resolved in favor of preparing a SEIS.” 134 If the agency determines that the 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. 135 “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.” 136

3. Environmental Assessment

At times, the need to require or not require an EIS is clear. An agency’s regulations may require an EIS, or a particular action may be categorically excluded from that requirement. 137 If the requirement for an EIS is not clear, however, the Council of Environmental Quality (“CEQ”) regulations allow an agency to prepare an EA in order to determine whether there will be a significant impact from the project. 138 If the agency concludes in the EA that there will be no significant effects from the proposed project, it may issue a FONSI in lieu of an EIS or SEIS. 139

The EA is to be a “concise public document” that provides sufficient evidence and analysis for determining whether to prepare an EIS and a comprehensive assessment of the impacts of the project. 140 An EA must have “brief discussions of the need for the proposal, of alternatives ... of the environmental impacts of the proposed action and alternatives, and a listing of agencies and persons consulted.” 141 “[T]he conclusions in the EA must be supported by ‘some quantified or detailed information,’ and the underlying environmental data relied upon to support the expert conclusions must be made available to the public” to allow for informed public comment on the project. 142 The EA should be prepared at the “ ‘earliest possible time to insure that planning and decisions reflect environmental values.’ ” 143

4. Cumulative Impact

The CEQ’s regulations also require that agencies consider the “cumulative impact” of a proposed project. 144 Cumulative impact denotes “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

5. Alternatives

Federal agencies must “study, develop, and describe appropriate alternatives to recommended courses of action in any proposal which involves unresolved conflicts concerning alternative uses of available resources.” 146 The purpose of this requirement is to provide evidence. that the agency considered different methods for obtaining its goal and to give the agency the ability to balance and weigh factors related to the different alternatives before making its choice to proceed with the project. 147 The consideration of alternatives “is the heart of the" [EIS].” 148 An agency issuing an EIS must “[r]igorously explore and objectively evaluate all reasonable alternatives,” consider a “no action” in which it is assumed that the project will not go' forward, “[i]nclude reasonable alternatives not within the jurisdiction of the lead agency,” and “[ijdentify the agency’s preferred alternative.” 149

Where an agency has made a valid FONSI, the range of alternatives it must assess is necessarily more limited than for an EIS, 150 however the requirement remains important. 151 Thus, when the agency has opted to begin the process with an EA, the document must include “brief discussions of the need for the proposal, of alternatives [to the proposed action], of the environmental impacts of the proposed action and alternatives, and a listing of agencies and persons consulted.” 152 An agency “need not consider an infinite range of alternatives, only reasonable or feasible ones.” 153 The discussion “need not be exhaustive,” but it should be “sufficient to permit a reasoned choice of alternatives as far as environmental aspects are concerned.” 154

6. Mitigation

One important element of NEPA is its requirement that an agency discuss methods for mitigating adverse environmental consequences. 155 An agency’s NEPA documentation must “[i]nclude appropriate mitigation measures not already included in the proposed action or alternatives.” 156 “When 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 EIS.” 157 However, “agencies should define ‘significance’ broadly and not rely on proposed mitigation measures as an excuse to avoid preparing an EIS.” 158

“[Mitigation measures have been found to be sufficiently supported when based on studies conducted by the agency ... or when they are likely to be adequately policed.” 159 For example, where a “proposal [was] modified prior to implementation by adding specific mitigation measures which completely compensate^] for any possible adverse environmental impacts stemming from the original proposal, the statutory threshold of significant environmental effects [was] not crossed and an EIS [was] not required.” 160 A proposed mitigation measure should be accompanied by some level of assurance as to its efficacy. An agency must study the likely effects of the measure, propose monitoring to determine how effective the planned mitigation would be, and consider alternatives in the event the measure failed. Otherwise, an agency may not rely on that mitigation measure to reduce environmental or cumulative impact below the level of significance that would require an EIS or an SEIS. 161

7. Standard of Review

The Administrative Procedure Act (“APA”) governs judicial review of an agency’s compliance with NEPA. 162 The APA 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.” 163 An agency’s decision is accorded a “presumption of regularity,” and the party challenging the decision has the burden of proof. 164

Review of an agency’s decision not to supplement an EIS is controlled by the “arbitrary and capricious” standard of sec tion 706(2)(A) of the APA. 165 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.” 166 In the Second Cir- ■ cuit, this review has two steps. First, the ■court considers “whether the agency took a-‘hard look’at the possible effects of the proposed action.” 167 Second, if the court' is.satisfied that the agency took a hard look,' the court must then determine “whether the agency’s decision was arbitrary or capricious.” 168 An agency’s decision'whether to issue- an EA or an SEIS, its consideration of cumulative impact and alternatives for the proposed project, and its proposal for mitigation measures are all subject to this inquiry.

D. Curing a NEPA Violation

After a NEPA violation has been found, a court must assess any new environmental review undertaken by that agency-before deciding on an appropriate remedy. While agencies are regularly given the opportunity to remedy a NEPA violation, 169 there are very few decisions from courts reviewing these remedial efforts. 170 Those courts that have evaluated remedial efforts have not conducted a de novo review. 171 In fact, a review of the case law demonstrates that courts rarély deviate from the well-established standard of arbitrary and capricious review following a remand to the agency. For example, in this circuit, a non-NEPA agency decision that was challenged pursuant to the APÁ after a remand was reviewed under the arbitrary and capricious standard. 172 Outside this circuit,- the two-step hard look and arbitrary and capricious standard was applied to an agency’s attempts to cure NEPA violations. 173

However, in applying that two-step standard at this stage, a court must pay particular attention to two additional issues. First, a court must make a “searching and careful” inquiry into whether the agency’s explanations were made objectively and in good faith. 174 The Supreme Court warned almost thirty years ago that courts should “critically review” agency explanations that come after a decision to proceed has been made because of the risk of “post-hoc rationalization.” 175 Similarly, courts in other circuits have noted that it is appropriate to “critically review” an agency’s NEPA documentation in order to guard against post-hoc rationalizations. 176 CEQ regulations prohibit an agency from preparing an EIS simply to justify decisions already made. 177 Under these circumstances, an agency must show, at a minimum, that it made a good faith and objective review of the potential environmental impacts of its proposed action. 178 Conversely, if the agency has postponed its project and objectively and in good faith reassessed the potential environmental impacts of its project, it is likely that the agency has cured its violation. 179

Second, in making this assessment, a court may conduct a “plenary review” in order to procure further documentation which allows it to assess the agency’s decision and the rationale supporting that decision. 180 To do so, a court may “obtain from the agency, either through affidavits or testimony, such additional explanation of the reasons for the agency decision as may prove necessary.” 181

In sum, a court must carefully examine each element of the NEPA documentation, including the alternatives analysis and proposed mitigation, first to determine whether the agency has satisfied the hard look standard, and, if so, whether the decision was arbitrary and capricious. A court may conduct this review by examining documents outside the agency’s record and must pay careful attention to the agency’s rationale.

E. Remedy

1. Injunctive Relief

“Injunctive relief ... has been used when appropriate for violations of NEPA.” 182 However, injunctive relief “does not follow automatically upon a finding of statutory violations” in the NEPA context. 183 “[A] court must [instead] balance the competing claims of injury and must consider the effect on each party of the granting or withholding of the requested relief.” 184 Thus, “[a]lthough the procedural requirements of NEPA must be followed scrupulously and cost or delay will not alone justify noncompliance with the Act ... it remains within the sound discretion of a district court to decline an injunction, even where deviations from prescribed NEPA procedures have occurred.” 185

Courts apply a four-part test when deciding whether to grant an injunction. The test requires: (1) irreparable injury, 186 (2) inadequacy of legal remedies, (3) that the balance of effects weighs in favor of the movant, and (4) that the injunction is in the public interest. 187 “[A] threat of irreparable injury must be proved, not assumed.” 188 If the injury is sufficiently likely, the balance of harm will likely favor an injunction. 189 However, a court must determine whether irreparable harm is “actual and imminent.” 190 In deciding whether irreparable harm is imminent, a court must look only at the current stage of the project, and not the effects of the project as a whole, or the projected effects at a later stage of the project. 191 Finally, injunctions issued under NEPA, like injunctions generally, must serve a remedial purpose. 192

2. Remand

If a court makes an express finding that there is a “substantial possibility” a project may have a significant effect on the human environment, the court may order the preparation of an EIS. 193 A party challenging the agency’s decision not to prepare an EIS need not show that the project “clearly” will have.a significant impact on the environment. 194 As noted, an EIS or SEIS should be prepared when the question of whether there will be a significant impact is a close one. 195 A court’s job is not to answer the question of whether the proposed action will have a significant impact on the environment, but merely to determine whether there is a “substantial possibility” that such an impact may occur. 196 While a court’s “task is to ensure NEPA compliance with the environmental policies,” it may not infringe on an agency’s decision where it has expertise. 197 “[T]he only role for the court is to insure that the agency has considered the environmental consequences.” 198

When the court is unsure whether the project will significantly affect the quality of the environment, “the appropriate remedy is to remand the case to the agency to correct the deficiencies in the record and in its analysis.” 199 A court may require the agency to reassess its NEPA analysis “in light of the proper standards.” 200 Thus, an agency may be ordered to prepare new NEPA-compliant documentation “under circumstances that ensure an objective evaluation” free of the pressures that are present when an agency has already undertaken to conduct a- project. 201

IV. DISCUSSION

Plaintiffs now claim that while the newly-produced EA has to some extent addressed the impact of the HDP on the RI/FS, and provides a coordination plan, the Corps has nonetheless failed to take a hard look at the impact the HDP will have on the RI/FS. Specifically, plaintiffs assert that the Corps has neglected to examine, among other things: (1) the possible impacts on EPA’s ability to characterize the site’s risk through sampling,, including whether pre-dredging samples will remain relevant after the HDP has dispersed sediments and altered flow in the channels, (2) the alternatives that would mitigate those possible impacts, (3) “possible impacts on remedial options,” and (4) “possible impacts from berth-deepening as part of the HDP and ■ maintenance dredging.” 202 Plaintiffs further contend that the Corps’ data is inadequate for its intended purpose and that the Corps’ methodology is flawed. 203 Finally, plaintiffs argue that the coordination plan fails to address the na ture, content, mechanisms, and monitoring provisions necessary for real coordination. 204

The Corps and Intervenors oppose plaintiffs’ request for relief on three grounds. First, they argue that plaintiffs’ request is not ripe because of the ongoing review of the Draft EA and Draft Amendment. Second, the Corps asserts that it has now taken a hard look at the possible impacts of the HDP on the RI/FS and cured any violations, making plaintiffs’ claim moot. Third, the Corps and Inter-venors argue that injunctive relief is inappropriate as plaintiffs have not shown irreparable harm.

During the original round of briefing in the remedy phase, the Corps asked that judicial review of the Draft EA and Draft Amendment be withheld so that it could complete the Final EA and Amendment, issue a final decision document, receive the requisite water quality certificate from the New Jersey Department of Environmental Protection under the Clean Water Act, and solicit the next contract for the HDP. 205 The Final EA was published in January 2006. As of February 16, 2006, the Corps had not received its water quality certificates. 206 In addition, it promised not to award the next contract until the Court’s ruling. 207

The harm plaintiffs will suffer here is procedural 208 and such harm accrues when the NEPA document is issued, not when action is taken or contracts issued. Thus, the lack of certification and contracting here does not affect the ripeness of plaintiffs’ claim. The Final EA is the Corps’ last step in the NEPA process. Judicial review was withheld until this document was published and both sides were given a chance to file supplementary briefs. Any further delay in review would not serve the goals of NEPA. Accordingly, plaintiffs’ claim is ripe.

B. The Merits of Plaintiffs’ NEPA Claim

The first question is whether the Corps has cured its NEPA violations thereby mooting plaintiffs’ claim for injunctive relief. To make this determination, the Court must assess whether the Corps has now. taken a hard look at the potential impacts of the HDP on the RI/FS and “convincingly documented its decision.” 209 Plaintiffs claim the Final EA still fails to do that and that the FONSI is arbitrary and capricious because it ignores likely significant impacts. 210 Plaintiffs assert that the Corps relies on faulty data to determine the “effects of dredge-induced resuspension on the distribution of contaminated sediment within the Superfund site.” 211 The Corps contends that it has taken a hard look and that it has “evaluat ed the public comments in a reasonable and prudent manner.” 212

Because the Corps’ EA was prepared after the decision to proceed with the HDP was made, there is a substantial risk of post-hoc rationalization. 213 The Corps originally asked that judicial review be suspended until it could solicit the next contract for the HDP, suggesting a desire to avoid any interference with its planned contracting as a result of NEPA compliance. 214 Intervenors have also staked enormous investments on the expeditious completion of the HDP. 215 Though the Corps has conducted several planning and coordination meetings with the EPA and promised to postpone issuing the next HDP contract until this Court’s order, two of its dredging projects have already begun. 216

There is a fine line between legitimate responses to public comment and post-hoc rationalization designed to justify a decision that has already been made. During the remedy phase, the Corps voluntarily conducted a NEPA review and prepared an EA. Once the Draft EA and Draft Amendment were published and the Corps received public comment on those documents, the Corps assessed the comments and took several of them into account. The Corps also responded to complaints in plaintiffs’ original briefs when preparing the Final EA. 217 However, most of the new matter in the Final EA consists of further explanations for decisions that were made long ago. 218

In sum, a review of the Final EA reveals a continued noncompliance with NEPA and a failure to take a hard look at the impact of the HDP on the RI/FS. First, it failed to take a hard look at the effect of resuspension on contaminant concentrations in the surface level sediments for two reasons: (1) it failed to assess resuspension rates for different geomorphic areas and arbitrarily relied on the use of averaging over each contract area; and (2) it did not identify and consider hot spots. Second, the Corps failed to assess the cumulative impact of maintenance dredging on the RI/FS. Third, the EA lacked a proper alternatives analysis. Finally, the Corps’ mitigation measures do not provide substantial assurance that possible impacts will be minimized.

1. Assessment of the Potential Impacts of the HDP on the RI/FS

a. Resuspension and the Amount of Contaminants Below the Surface

Plaintiffs argue that the Final EA fails to address potential adverse impacts of the HDP on the RI/FS by making “unsubstantiated” or “illogical assertions concerning the patterns of sediment resuspension and dispersion.” 219 In particular, plaintiffs note that the EA “assumes a uniform historical deposition rate in the flats over time and space” and that it “fails to consider the side slopes as a discrete area from the flats.” 220 Plaintiffs also contend that the EA fails to adequately account for many potential hot spots and their effect on the resuspension analysis. 221

The RI/FS is designed to study the distribution and concentration of dioxin and other contaminants in the sediment of the NBSA, evaluate the uptake of contaminants by aquatic biota, identify contaminant concentrations in the food web, and locate “hot spots” for short term remedial action. 222 The objectives of sampling include estimating “the approximate depth of a critical ‘horizon’ in the sediment bed” and preliminarily identifying “ ‘hot spots’ through statistical analyses.” 223

Several of the EA’s conclusions regarding resuspension and the amount of contaminants below the surface prejudge exactly the questions the RI/FS is meant to address by making assumptions about the average contaminant levels and the presence and/or size of hot spots. After a thorough review of the Final EA, I conclude that the Corps has still failed to take a hard look at the resuspension of sediment and contaminants caused by dredging. Specifically, the Corps has failed to take a hard look at (1) the possibility of different average resuspension rates in the various geomorphic areas as opposed to the average rates throughout a contract area, calculated without providing a separate analysis for channels, flats, and transitional areas, and (2) the existence and effect of hot spots.

(1) Averaging and the Selection of Areas for Study

The EA’s assessment of the potential impact of sediment resuspension on sampling is overly narrow. The RIWP will conduct sampling in the channels, sub-tidal flats, and in the transitional areas between the sub-tidal flats and navigational channels in order to “obtain data to characterize the horizontal and vertical distribution of COPCs in sediments.” 224 The EA purports to analyze the horizontal and vertical distribution of COPCs in sediments as well by assessing whether the concentration of contaminants below the surface is greater than that on the surface throughout the NBSA. 225 But, the EA does not distinguish between different geomorphic areas, such as tidal flats and transitional areas. 226 Nor does the EA give a reason for failing to analyze resuspension rates in different geomorphie areas.

The RIWP notes that “the behavior and stability of sediments ... present in the transitional areas between the Navigation Channels and the Subtidal Flats is largely unknown.” 227 As plaintiffs’ expert explains, “however large or small the area ... across which the resuspended sediments deposit, the depositional thickness will not be uniform throughout the area since resuspended sediments will not settle uniformly over the flats due to the complexity of the flows in these areas.” 228 In order to gain more information about this issue, the RIWP seeks to analyze whether deposition rates in the transitional slopes are more rapid than in the navigational channels or in the tidal flats and whether “the surface sediment chemistry [in transitional areas] reflect similar inputs as other geomorphie areas.” 229

Instead of acknowledging that it lacks sufficient data to address the possible difference in deposition rates or surface sediment chemistry in the transitional areas, the Corps uses the data from different geomorphie areas interchangeably. For example when the EA notes that there is a “relative paucity of data in the northeast portion of the region under study” the EA states that this lack of information was “mitigated by the availability of USACE cores along the edges of contract area SNB-1.” 230

The failure to distinguish between data from different geomorphie areas is exacerbated by the Corps’ use of averaging. Although the Corps noted the problem with using averages to make broad generalizations about resuspension rates and its effect on surface level contamination, it then failed to address whether the use of averaging was appropriate. Instead, it relied on averages of the cores it studied across the contract areas. Its own analysis undercuts the assumption that averages across contract areas are appropriate. For example, the Corps relies on the “spatial variability in existing surface sediment concentrations” in order to conclude that a possible 15% increase in the amount of DDT on the surface of the sediment “is unlikely to affect the RI/FS significantly.” 231 But the EA gives no indication that the Corps assessed the variations in concentrations of surface sediments throughout a contract area or in different geomorphie regions.

The EA also fails to consider the potentially different risks posed by resuspension in the tidal flats, the transitional areas, and the channels. The failure to separately analyze resuspension rates for different geomorphie areas results in the failure to effectively analyze resuspension rates caused by the HDP. This prevents informed public comment. And, as a result, the Court lacks sufficient information to assess whether there is a substantial possibility that the project could significantly affect the quality of the human environment.

(2) Hot Spots

Nor is there any real analysis of hot spots in the Final EA. ‘ One purpose of Phase 1 sampling in the RI/FS is to define “likely ‘hot spot[s].’ ” 232 The Corps only assessed the possibility of hot spots with respect to TCDD. Plaintiffs, in contrast, assessed the potential for hot spots of other contaminants besides TCDD and found “a substantial number of potential hot spots in the channels, often in clusters indicating a potentially larger size.” 233

Plaintiffs also contend that the Corps’ identification of potential TCDD hot spots was based on an arbitrary standard. The EA sets a value of 200 parts per trillion (“ppt”) for identifying TCDD hot spots and finds that the hot spots were limited in number. 234 The EA does not provide a basis for the use of the 200 ppt benchmark. According to plaintiffs, 100 ppt is still “ten times the maximum level deemed safe for exposure to marine organisms.” 235 A “larger number of potential dioxin hot spots” with a greater “potential spacial extent” would be evident in the channels if the Corps had looked at samples with TCDD concentrations of 100 ppt or higher. 236

The identification of hot spots is critically important because the contaminants in those areas could be targeted for quick remedial action. 237 However, as plaintiffs point out, if the hot spots are disturbed by dredging, resuspension and later deposition of the contaminants may disperse one hot spot and create a new one elsewhere. The Final EA’s attempt to dispose of the hot spots issue fails because it does not analyze (1) the scope of the hot spots, (2) whether the resuspension of contaminants other than TCDD will increase the surface concentration of each contaminant, or (3) whether resuspension of contaminants from hot spots is likely to result in new hot spots elsewhere.

b. Cumulative Impact

Plaintiffs also assert that the EA ignores the “cumulative effects” of maintenance dredging. 238 The Corps responded to plaintiffs’ earlier comments by noting that resedimentation from maintenance dredging “will remain localized and will not overlap with or accumulate on the resedimentation resulting from the deepening work.” 239 Plaintiffs argue that the “channels slated for maintenance dredging are directly adjacent to the channels included in the HDP” and that the EA’s assumption regarding localized resuspension is “new and completely unsubstantiated.” 240

The EA’s sole analysis of maintenance dredging focuses on whether samples taken from the areas slated for maintenance dredging will be affected. The EA concludes that the usefulness of those sam- pies will not be affected by maintenance dredging because they were taken prior to the dredging. 241 It also concludes that future sampling in those areas can be coordinated with the maintenance dredging. But this conclusion is contradicted by the Corps’ admission elsewhere in the EA that dredging performed after sampling has the potential to affect the usefulness of those samples. For example, the Corps admitted that in areas adjacent to the dredged areas “dredging may indirectly affect the interpretation of the data from these sediment cores by causing contaminated sediments from the channels to be resuspended and deposited onto the sediment surface areas where such cores will be taken.” 242 This observation is equally applicable to resuspension caused by maintenance dredging.

The EA also fails to look at the cumulative effects of maintenance dredging on samples taken in areas adjacent to the maintenance dredging. To assess whether maintenance dredging would have a cumulative effect on the RI/FS the Corps would need to consider whether resuspension in areas being dredged will accumulate with resuspension from maintenance dredging and increase the level of resuspended sediment to such an extent that the EA’s conclusions regarding the amount of contamination that would be redeposited on the surface are no longer valid. The EA fails to take a hard look at whether resus-pension caused by maintenance dredging will add to the resuspension caused by the HDP and at the cumulative effects of resedimentation from maintenance dredging that occurs in areas adjacent to or near the HDP dredging.

2. Alternatives

Plaintiffs claim that the Corps failed to consider all reasonable alternatives to the proposed HDP for minimizing the effects on the RI/FS. 243 Plaintiffs had originally suggested improving dredging protocols, by, for example, setting restrictions on the speed at which the dredging bucket is lowered, instituting independent inspections of the contractors’ compliance with dredging protocols, and establishing a more formal coordination plan. 244 In response, the Corps refashioned its analysis regarding best management practices for navigational dredging as an “alternatives” analysis. The Corps then claimed that the best management practices suggested by the plaintiffs were either adopted or found to be “unnecessary at the present time (albeit worthy of further analysis) or disadvantageous.” 245 Plaintiffs also claim, however, that the Final EA, while it addresses suggested dredging protocols, fails to consider “big picture” alternatives which would “alter the Corps’ overall approach.” 246

The EA’s alternatives analysis is notable for what it discusses and for what it fails to discuss. On the one hand, the analysis assesses best management practices for dredging. The Corps considered multiple dredging protocols for the HDP and while it postponed research into certain practices (such as use of positioning software), the EA provides an analysis of the benefits and harms of each protocol and the reasons for the adoption or rejection of each. On the other hand, the analysis does not discuss alternatives to the recommended course of action, including the preferred alternative 247 and the no action alternative. Instead, it notes summarily that the “no action alternative” was discussed in the 1999 FEIS. The EA provides no explanation for its failure to discuss these alternatives.

Plaintiffs note at least three potential alternatives that could have been studied. First, the Corps could have obtained and analyzed “critical sediment data that is forthcoming from [the] EPA before proceeding with contracts with the [NBSA].” 248 Second, the Corps could use the more detailed site-specific data obtained by the EPA to locate hot spots and to determine the level of care before dredging. 249 Third, the Corps could have considered conducting “remedial dredging.” 250 As plaintiffs note, the application of the Corps’ own Regulation — Hazardous, Toxic and Radioactive Waste (“HTRW”) Guidance for Civil Work Projects 251 — would have ensured that dredging in this HDP met standards for environmental remediation. 252

The HTRW Regulation sets procedures “to facilitate early identification and appropriate consideration of HTRW problems during a project” and directs the Corps to “identify and evaluate alternatives to respond to verified HTRW problems which cannot be avoided by project design.” 253 The key to whether these extra steps must be taken is whether or not the project involves HTRW. According to the Regulation, “dredged material and sediment beneath navigable waters proposed for dredging” qualify as HTRW when they are “within the boundaries of a site designated by the EPA or a state for response action (either a removal action or a remedial action) under CERCLA.” 254 The Corps’ reasons for dismissing the applicability of the HTRW Regulation have evolved during this litigation, but they are ultimately unconvincing. 255 The application of reme dial dredging measures to the HDP, as contemplated by the HTRW Regulation, was a reasonable alternative which could have been considered.

The purpose of the EA was to review the possibility that the RI/FS would be significantly affected by the HDP. Analysis of alternatives to the recommended course of action are at the heart of a NEPA document. 256 The EA should have included alternatives to the recommended course of action (the HDP), each of which would have had more or less of an impact on the RI/FS. The Corps was not required to address the precise alternatives suggested by plaintiffs. But, it was required to discuss sufficient alternatives to allow it to make a reasoned choice as to how to proceed with the HDP in light of the EPA’s ongoing study and remediation efforts. Instead, the EA relies on a restructured discussion of best management practices and the 1999 FEIS, which did not consider the impacts of dredging on the RI/FS, for its alternatives analysis. The EA once again fails to discuss alternatives, in violation of NEPA.

3. Mitigation

The final question is whether the Corps carefully addressed the form that coordination between the EPA and the Corps will take, as well as how the effectiveness of that coordination will be monitored. Plaintiffs urged the Corps to establish a clearly documented and effective coordination plan with a mechanism for problem-solving. 257 During the course of this litigation, the Corps adopted a coordination plan to ensure that any impacts on the RI/FS will be “identified, avoided, and minimized to the fullest extent possible.” 258 In addition, the Final EA provides information about monitoring the HDP, as described above.

Plaintiffs now claim that the EA’s coordination plan and the plan’s dispute resolution process amount to merely a “business as usual” approach which fails to set standards for resolving disputes and allows work to continue even while a dispute is pending. 259 Plaintiffs also claim that the monitoring plan leaves the “public to speculate about [its] adequacy.” 260

The coordination plan is a commendable addition to the EA, yet several questions remain. At present, coordination has allowed the sampling to proceed with minimal interference from the HDP. However, though the Corps intends to share data it gathers with the EPA, the coordination plan does not establish standards allowing the Corps to alter its dredging plan based on data it will receive from the EPA. Nor does it appear that any possible alterations to the plan, should it prove faulty, were proposed, researched, or subjected to public comments.

The EA makes several promises that it will alter its monitoring plan should it prove necessary. For example, the EA relies on a general promise that it will “as appropriate, reevaluate, the need for altering its dredging methods” in the NBSA through the use of its coordination plan and monitoring program. 261 The EA also explains that the Corps will follow “adaptive management practices as it moves through construction of its contracts,” thus allowing it to change future contracts should the data indicate it is necessary. 262 These promises, however, provide no assurance as to the efficacy of the mitigation measures. The Corps did not provide a proposal for monitoring how effective “adaptive management” would be. Nor did it give serious consideration to the adoption of alternatives to the dredging protocols should it need to reevaluate the ones currently in use. 263

The most important question is whether the coordination plan and monitoring are sufficient to ensure that the RI samples are relevant for preparation and possible execution of the remedial phase of the RI/FS. In an email which was included in the remedy phase documents, a key member of the coordination team, EPA Project Manager Elizabeth Butler, told the Corps that the HDP will probably delay the EPA’s ability to take remedial actions:

given your dredging activities I’m not sure what else we might do, except possibly some hot spot removals in the flats perhaps or some capping in the northern part of the bay where dredging is not a routine element. However I can say that other than any interim measures we would more than likely not be doing any final remediation until after your 50 ft project is complete. 264

The concern that final remediation must await the completion of the HDP is serious. The monitoring and coordination plans are intended to lessen the impact of the HDP on the RI/FS. But it is not at all clear whether the coordination and monitoring will truly minimize those impacts. The two projects are to be conducted in the same location and their goals are in conflict. The HDP’s goal is to remove sediment as cheaply and quickly as possible in order to allow bigger and better ships to use the Harbor. The EPA’s plan is aimed at careful selection and removal of contaminated sediment in that identical area. The Corps has still failed to adequately address how these projects can proceed simultaneously without threatening the timely remediation of the NBSA.

4. Conclusions Regarding NEPA Violations

The Corps had almost five months since the August 5 Opinion to produce and study the data it would need to decide whether the HDP would have a significant impact on the RI/FS. It nonetheless continues to rely on incomplete data, faulty assumptions, and unreliable averages. The lack of data also makes it impossible for the Corps to decide whether an SEIS is necessary and for the Court to determine whether there is a substantial possibility that the project could significantly affect the quality of the human environment. Under these circumstances, the Corps has not cured the violations previously found by the Court, and the FONSI was arbitrary and capricious.

C. Remedy

1. Irreparable Harm

In deciding whether to grant the requested injunction, this Court must determine whether ongoing dredging and contracting for the HDP is likely to irreparably harm the RI/FS. According to plaintiffs, the possible impacts that could flow from the dredging may require the EPA to re-sample data. Thus, plaintiffs claim that there is a risk that the dredging will (1) cause substantial delay in implementation of the RI/FS, (2) make it difficult to identify responsible parties, (3) increase the cost of study and remedy, and (4) jeopardize the effectiveness of cleanup by foreclosing cleanup options and/or delaying the implementation of the selected plan. 265 Plaintiffs argue that current dredging is likely to jeopardize the later usefulness of the sampling. 266 Defendants claim that it is “insufficient for plaintiffs to argue that the HDP will make the RI/FS process more difficult, more costly, or more time consuming.” 267 Rather, plaintiffs must prove that the “purported adverse effects of the HDP on the RI/FS process cannot be overcome.” 268

The risk of harm to the implementation of a clean up plan is real. The Corps admits that if removal of sediment affects the utility of surface samples, more samples will need to be taken in other areas, such as recently dredged areas. 269 This would undoubtedly delay the preparation of the FS. Particularly disturbing is the indication that remediation under the RI/FS might have to wait until certain stages of the HDP are completed. 270

However, it is not clear that the threat of irreparable harm is actual and imminent. The Corps has met regularly with the EPA and the two agencies have shared schedules for sampling and dredging and have discussed the data obtained through sampling that has already taken place. 271 The EPA has moved several sampling locations based on information about dredging activities. 272 The Corps and the EPA have regularly shared information regarding dredging and sampling locations. 273 Sampling has thus continued in areas which have not been dredged. Furthermore, it is not at all clear that the potential harm to the FS cannot be managed or remediated by the Corps and the EPA.

2. The Balance of Effects and the Public Interest

Intervenors argue that the balance of equities weighs against granting an injunc tion. Container Terminal notes that the public impact of an injunction will be great, causing loss of jobs and tax revenue in the New York and New Jersey Port. Container Terminal estimates that if the HDP is delayed past 2010, 274 thousands of port jobs will be lost, regional personal income will decrease by hundreds of millions of dollars, and tax revenue will also decline by tens of millions of dollars. 275 Container Terminal also notes that if the HDP is delayed or halted, more shipments would need to be brought into the area by truck and that would increase air pollution and traffic congestion. 276 In addition, if larger ships cannot enter the Port, “light-ering” (a process of transferring shipments to smaller and lighter ships for transportation into the harbor) would increase, heightening the risk of an accident. 277 Finally, Container Terminal points out that there are environmental risks in allowing the sediment to remain in the harbor. 278 Donjon also argues that the “suspension of future, contracts” will “idle equipment, cause layoffs of personnel who anticipated employment through the course of the entire HDP” and “prevent Donjon from recouping its huge investment.” 279

While continuation of .economic-development in the Port and the completion of the HDP will certainly benefit the region, the dire predictions of Donjon and Container Terminal are somewhat overstated. Plaintiffs do not request that the HDP be discontinued, but only that it be delayed until the completion of NEPA-compliant documentation. Intervenors do not estimate the loss of investments, jobs, and tax revenue if there were a limited delay of three to nine months. 280

Container Terminal also notes that allowing the contaminated sediment to remain in the environment would harm the public. Plaintiffs agree but for an entirely different reason. From plaintiffs’ perspective, if the dredging skews the EPA’s sampling analysis, the contamination is likely to remain in the environment longer due to the harm this will cause to the FS, and the related delay to final remediation.

In addition, even if an SEIS takes twelve months, the only contracts that would be affected by this delay would be the contracts in the NBSA scheduled during. that period. 281 Some of the HDP contracts are for areas outside the NBSA and could be expedited while the contracts in the NBSA are postponed. For example, as plaintiffs’ expert points out, “the accessibility of deep draft ships [to Container Terminal] depends on the deepening of channels outside the NBSA” and the Corps has “ample.opportunity to mitigate any impacts” by adjusting its dredging schedule between contract areas. 282

3. Adequacy of Legal Remedies

The discussion of irreparable harm, public interest, and the balance of equities is premature, however, because the plaintiffs are not without a legal remedy: remand. The question of whether the HDP will have significant adverse impacts on the RI/FS is one that the Corps must decide. Here, the Corps already prepared an EA to assess the possible impacts of the HDP on the RI/FS. The Corps has demonstrated that it is willing to look at the effects of the HDP. Though the EA did not cure the Corps’ NEPA violations, there is no indication that a remand to the Corps with instructions to correct the remaining deficiencies in the EA and a careful timetable for those corrections will be disregarded. At least in the short term an injunction is not warranted. A remand strikes a delicate balance between the need to enforce NEPA’s procedural guarantees and the equitable considerations cited by the Corps and Intervenors.

On remand, the Corps must consider the issues that were inadequately addressed in its Final EA, including alternatives to the projects and mitigation measures. After doing so, it should reconsider its FONSI in light of its additional investigation and the applicable legal standard.

The Corps should also take affirmative steps to ensure that its review is objective and made in good faith. The current atmosphere of ongoing dredging, complete with contractors who have intervened in this case and made substantial investments in the hopes of either winning dredging contracts and/or obtaining more container traffic, is not one which will reasonably allow the Corps to assess the potential environmental impacts of the HDP on the RI/FS. During the pendency of this remedy phase, the Corps voluntarily agreed to postpone contracting for the HDP. Thus, there is no reason to believe that the agency will not choose a manner for conducting its review that allows it to do so objectively and in good faith. 283 Should a new EA again be challenged, the Corps will have to demonstrate that it has acted objectively and in good faith. 284

In addition, work for the Corps’ next planned maintenance dredging contract is scheduled to begin in April. 285 Thus, time is of the essence. On remand, the Corps must produce sufficient data to make a reasoned decision, within the next four months, as to whether an SEIS is necessary. This Court retains jurisdiction to consider a renewed request for injunctive relief at that time.

A remand for reconsideration of the EA rather than an injunction carefully balances judicial review of the procedures followed with the agency’s independent de-cisionmaking power regarding the substan tive issues before it. 286 My review of the voluminous record reveals that the Corps has now made some progress towards addressing the interactions between the HDP and the RI/FS. In addition, the sampling planned by the EPA in the near future will aid and assist the Corps in taking a genuine hard look at the effects of dredging on resuspension, the hot spots, the appropriate use of averaging, and alternatives to the project. A remand in this case may improve the agency’s deci-sionmaking processes and allow it to study the effects of dredging on the RI/FS by further coordination with the EPA. It may also encourage the Corps to continue its analysis based on the data being gathered by the EPA so as to not prejudge the very questions being asked by the EPA.

V. CONCLUSION

For the foregoing reasons, plaintiffs’ request is granted in part and denied in part. Plaintiffs request for injunctive relief is denied. The EA is remanded to the Corps for reconsideration. The Corps is ordered to produce sufficient data to make -a reasoned decision, within four months, as to whether an SEIS is necessary.

The Clerk of the Court is directed to close these motions (docket # 29, 41). This Court retains jurisdiction to determine whether the final NEPA documentation has cured the deficiencies noted in this opinion. A conference is scheduled for April 7, 2006 at 10:00 a.m. in courtroom 15C.

255 . Where the Corps originally dismissed the HTRW Regulation by stating that “[cjurrently, no part of the HDP occurs within the limits of the CERCLA (Superfund) site,” the EA now acknowledges that the dredging locations in the Newark Bay and in parts of the Arthur Kill and Kill van Kull are part of the Study Area. Compare Draft EA at 4, USACE I: 0020093 with EA at 8, USACE IV: 0022012 (noting that "dredging project areas ... that coincide with the southern half of the [NBSA] account for approximately forty six percent of the HDP area”). The Superfund Site has been expanded to include the NBSA. See Amendment to the EA at 2-3, USACE IV: 0022111; Final National Priorities List (NPL) Sites Environmental Protection Agency, Region 9 (last updated Feb. 8, 2006), available at http:llwww.epa.govlsuperfu.nd/siteslqueryl queryhtm/nplfinl.htm (“The Diamond Alkali Superfund Site includes the former pesticides manufacturing plant and surrounding properties at 80 and 120 Lister Avenue in Newark, New Jersey, the Lower Passaic River Study Area, the Newark Bay Study Area and the extent of contamination.”). The EA now asserts that the material is not HTRW because it has yet to be classified by the EPA as a hazardous substance under CERCLA and that the Corps must wait until the RI results in a Record of Decision (a public document that explains which cleanup alternatives will be used) to determine whether the dredged material consists of HTRW. See EA at 6, USACE IV: 002210; Application of HTRW Regulation to Corps navigation deepening dredging in NBSA at 6, Appendix C, EA, USACE IV: 0022080. For dredged material, the HTRW Regulation does not require a record of decision or the designation of a hazardous substance. In fact, the HTRW Regulation states that dredged material qualifies as HTRW if it is part of a site designated for remedial action under CERCLA, as this site is.
