Defendants,

&

EMPIRE OFFSHORE WIND LLC, et al.,

Intervenor-Defendants.

MEMORANDUM OPINION

Plaintiffs allege that the government unlawfully approved an offshore wind farm off the

coast of New York and New Jersey. Intervenor-Defendants Empire Offshore Wind LLC and

Empire Leaseholder LLC (collectively, Empire Wind), who are building the wind farm, move to

dismiss on various grounds. ECF 20. For the reasons that follow, the Court grants in part and

denies in part the motion.

I. BACKGROUND

A. Factual Background

The Outer Continental Shelf Lands Act (OCSLA) authorizes the Secretary of Interior to

issue leases for renewable energy projects, see 43 U.S.C. § 1337(p), and the Bureau of Ocean

Energy Management (BOEM) manages the approval process for offshore wind projects, see 30

C.F.R. §§ 585.100, 585.102. In late 2016, Empire Wind’s parent company won an auction held

1 by BOEM for a lease to build a wind farm off the coast of New York and New Jersey. ECF 19-1

at 2–3. In January 2020, Empire Wind submitted a Construction and Operations Plan to BOEM.

Id. at 5. After several rounds of modifications, BOEM approved the Plan in February 2024. Id.

at 5–6. Later that year, BOEM reissued separate approvals for two stages of construction: Empire

Wind 1 and Empire Wind 2. Id. at 6.

As part of that review process, BOEM prepared an Environmental Impact Statement

pursuant to the National Environmental Policy Act (NEPA). See 42 U.S.C. § 4336(b)(1). BOEM

received comments on the Statement both after it issued a Notice of Intent in June 2021 and after

it published a draft Environmental Impact Statement in November 2022. ECF 19-1 at 7. After

consulting with other government entities and considering the comments it received, BOEM

published the final version of the Environmental Impact Statement for the Empire Wind Project in

September 2023. Id. at 8. A few months later, BOEM and the National Marine Fisheries Service

(NMFS) jointly issued a Record of Decision that concluded the NEPA review process. Id.

Empire Wind also sought authorization to conduct construction activities that could affect

wildlife in the area. In December 2021, it requested a five-year Letter of Authorization from

NMFS to “take” various marine mammals incidental to construction of the Empire Wind Project

in compliance with the Marine Mammal Protection Act (MMPA).1 Id. at 4. That Act permits

NMFS to authorize the taking of “small numbers of marine mammals of a species or population

stock if the Secretary, after notice . . . and opportunity for public comment[,] . . . finds that the total

1 “The term ‘take’ means to harass, hunt, capture, or kill, or attempt to harass, hunt, capture, or kill any marine mammal.” 16 U.S.C. § 1362(13). The MMPA distinguishes between two levels of harassment takings. Level A harassment encompasses “any act of pursuit, torment, or annoyance which . . . has the potential to injure a marine mammal or marine mammal stock in the wild.” Id. § 1362(18)(A)(i), (C). Level B harassment covers “any act of pursuit, torment, or annoyance which . . . has the potential to disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns.” Id. § 1362(18)(A)(ii), (D).

2 of such taking during each five-year (or less) period concerned will have a negligible impact on

such species or stock and will not have an unmitigable adverse impact on the availability of such

species or stock for taking for subsistence uses.” 16 U.S.C. § 1371(a)(5)(A)(i). Following notice

and comment and after reviewing the Environmental Impact Statement, NMFS issued a Letter of

Authorization in February 2024 for the Project that permits the incidental taking of marine

mammals through February 2029. ECF 19-1 at 5. Of relevance here, the Letter authorizes annual

Level B harassment of up to 31.9 percent of Northern Migratory Coastal Bottlenose Dolphins. See

Taking Marine Mammals Incidental to the Empire Wind Project, Offshore New York, 89 Fed.

Reg. 11342, 11416 (Feb. 14, 2024). In January 2025, NMFS reissued the Letter with minor

changes. ECF 19-1 at 5.

With all relevant approvals secured, construction of the onshore portion of the Empire

Wind Project began in April 2024. ECF 19-2 at 3. In-water installation of export cables to transfer

electricity commenced in July 2024. Id. at 4. BOEM issued a suspension order in April 2025 that

paused construction as part of the Department of Interior’s general review of offshore wind

projects but then lifted it after a month. ECF 17-1 at 1, 3. Building of monopile foundations for

the wind turbines started in June 2025. ECF 19-2 at 4. And all construction for the Empire Wind 1

portion of the Project is set to conclude by the end of 2026. Id. at 6.

B. Procedural History

In April 2023, Save Long Beach Island, Inc., and Dr. Robert Stern filed a lawsuit in the

District of New Jersey challenging authorizations issued by NMFS that permitted the incidental

takings of marine mammals for several offshore wind projects. Complaint at 1–4, Save Long

Beach Island v. U.S. Dep’t of Com., No. 3:23-cv-1886 (D.N.J. Apr. 4, 2023). In February 2024,

the district court dismissed the suit without prejudice for mootness and lack of standing. See Save

3 Long Beach Island v. U.S. Dep’t of Com., 721 F. Supp. 3d 317, 335, 340 (D.N.J. 2024). Save

Long Beach Island and Stern then filed an amended complaint the next month that explicitly

challenged the Letter of Authorization for the Empire Wind Project. Amended Complaint at 15,

Save Long Beach Island v. U.S. Dep’t of Com., No. 3:23-cv-1886 (D.N.J. Mar. 29, 2024). But, in

June 2025, the district court granted summary judgment to Empire Wind and the government

regarding the Letter of Authorization. See Save Long Beach Island v. U.S. Dep’t of Com., 794 F.

Supp. 3d 273, 332 (D.N.J. 2025).

In July 2025, Save Long Beach Island and Stern—along with new Plaintiffs Save the East

Coast, Inc.; Protect Our Coast – LINY; Captain Alan Shinn; and the Borough of Seaside Park—

filed this suit against various Federal Defendants, alleging that the Letter of Authorization and the

Construction and Operations Plan for the Empire Wind Project violate the MMPA, NEPA, and

OCSLA. ECF 1 at 2–3. Empire Wind intervened as a Defendant. See Min. Order of Aug. 8, 2025.

In August 2025, Plaintiffs moved for the Court to stay the Letter of Authorization and

Construction and Operations Plan or, in the alternative, to enter a preliminary injunction to halt

construction. ECF 17. Their motion raised only their claim under the MMPA, arguing that the

government’s approval exceeded that statute’s allowance of takings of “small numbers of marine

mammals of a species or population stock” because it permits Level B harassment of 31.9 percent
