UNITED STATES DEPARTMENT OF COMMERCE, et al.,

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

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).

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

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 of the Northern Migratory Coastal Bottlenose Dolphin stock. 16 U.S.C. § 1371(a)(5)(A). The Court denied that motion given that Plaintiffs failed to establish irreparable harm absent a stay or preliminary injunction and the equities did not weigh in their favor. See Save Long Beach Island, Inc. v. U.S. Dep’t of Com., No. 25-cv-2214, 2025 WL 2996157, at *3–7 (D.D.C. Oct. 24, 2025).

The Court now considers Empire Wind’s motion to dismiss the case for lack of subject-

matter jurisdiction and failure to state a claim.2 ECF 20. In lieu of filing their own motion to dismiss, the Federal Defendants filed an unopposed motion to defer their deadline to respond to Plaintiffs’ complaint until 30 days after the Court resolves Empire Wind’s motion to dismiss. ECF 25. The Court granted that request. See Min. Order of Oct. 3, 2025.
