Takes of Marine Mammals Incidental to Specified Activities; Taking Marine
Mammals Incidental to Invenergy Wind Offshore, LLC's Marine Site
Characterization Surveys in the New York Bight
AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA), Commerce.
ACTION: Notice; proposed incidental harassment authorization renewal; request for
comments on proposed authorization.
SUMMARY: NMFS received a request from Invenergy Wind Offshore, LLC (IWO) for
the renewal of their currently active incidental harassment authorization (IHA)
(hereinafter, the “initial IHA”) to take marine mammals incidental to marine site
characterization surveys in the New York Bight, specifically within the Bureau of Ocean
Energy Management (BOEM) Commercial Lease of Submerged Lands for Renewable
Energy Development on the Outer Continental Shelf (OCS) Lease Area OCS-A 0542
(Lease Area) and associated Export Cable Route (ECR) survey area (ECR Area) . IWO’s
specified activities are identical to those included in the initial IHA. The initial IHA
expires on July 30, 2024. Pursuant to the Marine Mammal Protection Act, prior to issuing
the initial IHA, NMFS requested comments on both the proposed IHA and the potential
for renewing the initial authorization if certain requirements were satisfied. The renewal
requirements have been satisfied, and NMFS is now providing an additional 15-day
comment period to allow for any additional comments on the proposed renewal not
previously provided during the initial 30-day comment period.

DATES: Comments and information must be received no later than [INSERT DATE 15
DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].
ADDRESSES: Comments should be addressed to Jolie Harrison, Chief, Permits and
Conservation Division, Office of Protected Resources, National Marine Fisheries Service,
and should be submitted via email to ITP.demarest@noaa.gov.
Instructions: NMFS is not responsible for comments sent by any other method, to

SUPPLEMENTARY INFORMATION:
Background

The Marine Mammal Protection Act (MMPA) prohibits the “take” of marine
mammals, with certain exceptions. Sections 101(a)(5)(A) and (D) of the MMPA (16
U.S.C. 1361 et seq.) direct the Secretary of Commerce (as delegated to NMFS) to allow,
upon request, the incidental, but not intentional, taking of small numbers of marine
mammals by U.S. citizens who engage in a specified activity (other than commercial
fishing) within a specified geographical region if certain findings are made and either
regulations are promulgated or, if the taking is limited to harassment, an incidental
harassment authorization is issued.
Authorization for incidental takings shall be granted if NMFS finds that the taking
will have a negligible impact on the species or stock(s) and will not have an unmitigable
adverse impact on the availability of the species or stock(s) for taking for subsistence
uses (where relevant). NMFS must prescribe the permissible methods of taking and other
“means of effecting the least practicable adverse impact” on the affected species or stocks
and their habitat, paying particular attention to rookeries, mating grounds, and areas of
similar significance, and on the availability of such species or stocks for taking for certain
subsistence uses (referred to here as “mitigation measures”). NMFS must also prescribe
requirements pertaining to monitoring and reporting of such takings. The definition of
key terms such as “take,” “harassment,” and “negligible impact” can be found in the
MMPA and NMFS’s implementing regulations (see 16 U.S.C. 1362; 50 CFR 216.3; 50
CFR 216.103).
NMFS’ regulations implementing the MMPA at 50 CFR 216.107(e) indicate that
IHAs may be renewed for additional periods of time not to exceed one year for each
reauthorization. In the notice of proposed IHA for the initial IHA, NMFS described the
circumstances under which we would consider issuing a renewal for this activity and
requested public comment on a potential renewal under those circumstances. Specifically,
on a case-by-case basis, NMFS may issue a one-time 1-year renewal of an IHA following

notice to the public providing an additional 15 days for public comments when (1) up to
another year of identical, or nearly identical, activities as described in the Detailed
Description of Specified Activities section of the initial IHA issuance notice is planned or
(2) the activities as described in the Description of the Specified Activities and
Anticipated Impacts section of the initial IHA issuance notice would not be completed by
the time the initial IHA expires and a renewal would allow for completion of the
activities beyond that described in the DATES section of the notice of issuance of the
initial IHA, provided all of the following conditions are met:
1.

A request for renewal is received no later than 60 days prior to the needed

renewal IHA effective date (recognizing that the renewal IHA expiration date cannot
extend beyond 1 year from expiration of the initial IHA);
2.

The request for renewal must include the following:

●

An explanation that the activities to be conducted under the requested

renewal IHA are identical to the activities analyzed under the initial IHA, are a subset of
the activities, or include changes so minor (e.g., reduction in pile size) that the changes
do not affect the previous analyses, mitigation and monitoring requirements, or take
estimates (with the exception of reducing the type or amount of take); and
●

A preliminary monitoring report showing the results of the required

monitoring to date and an explanation showing that the monitoring results do not indicate
impacts of a scale or nature not previously analyzed or authorized; and
3.

Upon review of the request for renewal, the status of the affected species

or stocks, and any other pertinent information, NMFS determines that there are no more
than minor changes in the activities, the mitigation and monitoring measures will remain
the same and appropriate, and the findings in the initial IHA remain valid.
An additional public comment period of 15 days (for a total of 45 days), with
direct notice by email, phone, or postal service to commenters on the initial IHA, is

provided to allow for any additional comments on the proposed renewal. A description of
the renewal process may be found on our website at:
http://www.fisheries.noaa.gov/national/marine-mammal-protection/incidentalharassment-authorization-renewals. Any comments received on the potential renewal,
along with relevant comments on the initial IHA, have been considered in the
development of this proposed IHA renewal and a summary of agency responses to
applicable comments is included in this notice. NMFS will consider any additional public
comments prior to making any final decision on the issuance of the requested renewal,
and agency responses will be summarized in the final notice of our decision.
National Environmental Policy Act
This action is consistent with categories of activities identified in Categorical
Exclusion B4 (incidental take authorizations with no anticipated serious injury or
mortality) of the Companion Manual for NOAA Administrative Order 216-6A, which do
not individually or cumulatively have the potential for significant impacts on the quality
of the human environment and for which we have not identified any extraordinary
circumstances that would preclude this categorical exclusion. Accordingly, NMFS
determined that the issuance of the initial IHA qualified to be categorically excluded
from further NEPA review. NMFS has preliminarily determined that the application of
this categorical exclusion remains appropriate for this renewal IHA.
History of Request
On July 19, 2023, NMFS issued the initial IHA to IWO to take small numbers of
marine mammals incidental to site characterization surveys off the coast of New York
and New Jersey in the New York Bight (88 FR 47846, July 25, 2023), effective from July
31, 2023 through July 30, 2024. On May 3, 2024, NMFS received a request for the
renewal of the initial IHA, which was deemed adequate and complete on May 24, 2024.
As described in the application for renewal IHA, the specified activities for which

incidental take is requested are identical to those included in the initial authorization. As
required, IWO provided a preliminary monitoring report, which shows that it has
implemented the required mitigation and monitoring measures and no impacts of a scale
or nature not previously analyzed or authorized have occurred as a result of the activities
conducted.
Description of the Specified Activities and Anticipated Impacts
IWO requested to conduct an additional year of marine site characterization
surveys with high-resolution geophysical (HRG) surveys and geotechnical sampling from
July 31, 2024 through July 30, 2025. Only HRG surveys are expected to have the
potential to cause incidental take of small numbers of marine mammals. The survey will
consist of up to 12,818 km of trackline in waters off the coast of New Jersey and New
York in the New York Bight, which is within the Bureau of Ocean Energy Management
(BOEM) lease area OCS-A 0542 and the associated Export Cable Route (ECR) Area.
Hereafter, both the areas are referred to as the Survey Area.
The purpose of IWO’s proposed surveys is to provide sufficient data to meet
BOEM guidelines and support the development of offshore wind facilities in the Survey
Area. Specifically, data collected would support site characterization, siting, and
engineering design of offshore wind facilities including turbine generators, offshore
substations, submarine cables and data necessary for project review requirements. IWO
will have a maximum of 3 vessels surveying concurrently. Underwater sounds produced
from sparkers and boomers during IWO’s surveys has the potential to result in Level B
harassment of 15 species and 16 stocks of marine mammals. Activities proposed for the
IHA renewal are identical in scope, effort, potential harassment to marine mammals, and
mitigation measures as the final proposed IHA (88 FR 47846, July 25, 2023).
Detailed Description of the Activity

A detailed description of the surveys for which incidental take is proposed here
may be found in the Federal Register Notices of the initial Proposed IHA (88 FR 32735,
May 22, 2023). The location, duration, and nature of the activities, including the types of
equipment planned for use, are identical to those described in the previous notices. The
proposed renewal would be effective for a period not exceeding 1 year from July 30,
2024.
Description of Marine Mammals
A description of the marine mammals in the area of the activities for which
authorization of take is proposed here, including information on abundance, status,
distribution, and hearing, may be found in the Federal Register notice of the proposed
IHAs (88 FR 32735, May 22, 2023) for the initial IHA. NMFS has reviewed the
monitoring data from the initial IHA, the draft 2023 SARs, which included updates to
certain stock abundances since the initial IHA was issued, information on relevant
unusual mortality events (UME), and other scientific literature. The draft 2023 SAR
updated the population estimate (Nbest) of North Atlantic right whales from 338 to 340
and annual mortality and serious injury from 31.2 to 27.2. The updated population
estimate in the draft 2023 SAR is based upon sighting history through December 2021
(89 FR 5495, January 29, 2024). Total annual average observed North Atlantic right
whale mortality during the period 2017–2021 was 7.1 animals and annual average
observed fishery mortality was 4.6 animals, however, estimates of 27.2 total mortality
and 17.6 fishery mortality account for undetected mortality and serious injury (89 FR
5495, January 29, 2024). In October 2023, NMFS released a technical report identifying
that the North Atlantic right whale population size based on sighting history through
2022 was 356 whales, with a 95 percent credible interval ranging from 346 to 363
(Linden, 2023).
The population estimates (Nbest) also increased for the North Atlantic stock of

sperm whales, the Western North Atlantic Offshore stock of common bottlenose
dolphins, Western North Atlantic stocks of Risso’s dolphins, Atlantic spotted dolphins,
and gray seals. However, abundance estimates slightly decreased for the Western North
Atlantic stocks of common dolphins and harbor porpoises. NMFS has determined there is
no new information that affects which species or stocks have the potential to be affected
or the pertinent information in the Description of the Marine Mammals in the Area of
Specified Activities contained in the supporting documents for the initial IHA.
Potential Effects on Marine Mammals and their Habitat
A description of the potential effects of the specified activity on marine mammals
and their habitat for the activities for which an IHA is proposed here may be found in the
Notice of the proposed IHA (88 FR 32735, May 22, 2023) for the initial IHA. NMFS has
reviewed the monitoring data from the initial IHA, recent draft stock assessment reports,
information on relevant UMEs and other scientific literature and determined that there is
no new information that affects our initial analysis of impacts on marine mammals and
their habitat.
Estimated Take
A detailed description of the methods and inputs used to estimate take for the
specified activity are found in the Federal Register Notice of the Final IHA (88 FR
47846, July 25, 2023) for the initial IHA. Specifically, the source levels, days of
operation, and marine mammal density/occurrence data applicable to this authorization
remain unchanged from the initial IHA. Similarly, the stocks taken, methods of take, and
type of take remain unchanged from the initial IHA, as do the number of takes, which are
indicated below in table 1.

Description of Proposed Mitigation, Monitoring and Reporting Measures

The proposed mitigation, monitoring, and reporting measures included as requirements in
this proposed IHA are identical to those included in the Federal Register notice
announcing the issuance of the initial IHA (88 FR 47846, July 25, 2023) and the
discussion of the least practicable adverse impact determination included in that
document remains applicable and accurate.
Comments and Responses
As noted previously, NMFS published a notice of a proposed IHA (88 FR 32735;
May 22, 2023) and solicited public comments on both our proposal to issue the initial
IHA for marine site characterization surveys off the coast of New York and New Jersey
in the New York Bight and on the potential for a renewal IHA, should certain
requirements be met.
All public comments were addressed in the notice announcing the issuance of the
initial IHA (88 FR 47846, July 25, 2023). Below, we describe how we have addressed,
with updated information where appropriate, any comments received that specifically
pertain to the renewal of the 2024 IHA.
Comment: Oceana raised objections to NMFS' proposed renewal process for
potential extension of the 1-year IHA with an abbreviated 15-day public comment period.
Oceana recommended that an additional 30-day public comment period is necessary for
any IHA renewal request.
Response: NMFS' IHA renewal process meets all statutory requirements. In prior
responses to comments about IHA renewals ( e.g.,84 FR 52464, October 2, 2019; 85 FR
53342, August 28, 2020), NMFS explained the IHA renewal process is consistent with
the statutory requirements contained in section 101(a)(5)(D) of the MMPA, and further,
promotes NMFS' goals of improving conservation of marine mammals and increasing
efficiency in the MMPA compliance process. Therefore, we intend to continue to
implement the existing renewal process.

All IHAs issued, whether an initial IHA or a renewal, are valid for a period of not
more than 1 year. The public has 30 days to comment on proposed IHAs, with a
cumulative total of 45 days for IHA renewals. The notice of the proposed IHA published
in the Federal Register on May 22, 2023 (88 FR 32735) provided a 30-day public
comment period and made clear that NMFS was seeking comment on the proposed IHA
and the potential issuance of an IHA renewal for this survey. As detailed in the Federal
Register notice for the proposed IHA and on the agency's website, eligibility for renewal
is determined on a case-by-case basis, renewals are subject to an additional 15-day public
comment period, and the renewal is limited to up to another year of identical or nearly
identical activities as described in the Description of Proposed Activities section of the
proposed IHA notice or the activities described in the Description of Proposed Activities
section of the proposed IHA notice would not be completed by the time the IHA expires
and a renewal would allow for completion of the activities beyond that described in the
Dates and Duration section of this notice. NMFS' analysis of the anticipated impacts on
marine mammals caused by the applicant's activities covers both the initial IHA period
and the possibility of a 1-year renewal. Therefore, a member of the public considering
commenting on a proposed initial IHA also knows exactly what activities (or subset of
activities) would be included in a proposed renewal IHA, the potential impacts of those
activities, the maximum amount and type of take that could be caused by those activities,
the mitigation and monitoring measures that would be required, and the basis for the
agency's negligible impact determinations, least practicable adverse impact findings,
small numbers findings, and (if applicable) the no unmitigable adverse impact on
subsistence use finding—all the information needed to provide complete and meaningful
comments on a possible renewal at the time of considering the proposed initial IHA.
Reviewers have the information needed to meaningfully comment on both the immediate

proposed IHA and a possible 1-year renewal, should the IHA holder choose to request
one.
While there would be additional documents submitted with a renewal request, for
a qualifying renewal these would be limited to documentation that NMFS would make
available and use to verify that the activities are identical to those in the initial IHA, are
nearly identical such that the changes would have either no effect on impacts to marine
mammals or decrease those impacts, or are a subset of activities already analyzed and
authorized but not completed under the initial IHA. NMFS would also need to confirm,
among other things, that the activities would occur in the same location; involve the same
species and stocks; provide for continuation of the same mitigation, monitoring, and
reporting requirements; and that no new information has been received that would alter
the prior analysis. The renewal request would also contain a preliminary monitoring
report, in order to verify that effects from the activities do not indicate impacts of a scale
or nature not previously analyzed. The additional 15- day public comment period, which
includes NMFS' direct notice to anyone who commented on the proposed initial IHA,
provides the public an opportunity to review these few documents, provide any additional
pertinent information, and comment on whether they think the criteria for a renewal have
been met. Combined together, the 30-day public comment period on the initial IHA and
the additional 15-day public comment period on the renewal of the same or nearly
identical activities, provides the public with a total of 45 days to comment on the
potential for renewal of the IHA.
In addition to the IHA renewal process being consistent with all requirements
under section 101(a)(5)(D) of the MMPA, it is also consistent with Congress' intent for
issuance of IHAs to the extent reflected in statements in the legislative history of the
MMPA. Through the description of the process and express invitation to comment on
specific potential renewals in the Request for Public Comments section of each proposed

IHA, the description of the process on NMFS' website, further elaboration on the process
through responses to comments such as these, posting of substantive documents on the
agency's website, and provision of 30 or 45 days for public review and comment on all
proposed initial IHAs and renewals respectively, NMFS has ensured that the public is
“invited and encouraged to participate fully in the agency's decision-making process,” as
Congress intended.
For more information, NMFS has published a description of the Renewal process
on our website (available at https://www.fisheries.noaa.gov/national/marine-mammalprotection/incidental-harassment-authorization-renewals)
Preliminary Determinations
NMFS proposes to authorize incidental take of small numbers of marine
mammals from specified activities that are identical to those analyzed in the initial IHA
and to require mitigation, monitoring, and reporting measures that are also identical to
those in the initial IHA. The number of takes by Level B harassment proposed is equal to
that authorized in the initial IHA. In the initial IHA, NMFS determined that IWO’s
specified activities would have a negligible impact on the affected species and/or stocks
and the authorized take for each stock would be small relative to individual stock
abundance (less than one third).
NMFS has preliminarily concluded that there is no new information suggesting
that our analysis or findings should change from those reached for the initial IHA. This
includes consideration of the estimated abundance of seven stocks decreasing/increasing
slightly. Specifically, NMFS is proposing to authorize six takes of North Atlantic right
whales by Level B harassment only, and the impacts resulting from the project’s
activities are neither reasonably expected nor reasonably likely to adversely affect the
stock through effects on annual rates of recruitment or survival. Additionally,

approximately 1.76 percent of the stock abundance is proposed for take by Level B
harassment.
Based on the information and analysis contained here and in the referenced
documents, NMFS has determined the following: (1) the required mitigation measures
will effect the least practicable impact on marine mammal species or stocks and their
habitat; (2) the authorized takes will have a negligible impact on the affected marine
mammal species or stocks; (3) the authorized takes represent small numbers of marine
mammals relative to the affected stock abundances; (4) IWO’s activities will not have an
unmitigable adverse impact on taking for subsistence purposes as no relevant subsistence
uses of marine mammals are implicated by this action, and; (5) appropriate monitoring
and reporting requirements are included.
Endangered Species Act
Section 7(a)(2) of the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.)
requires that each Federal agency insure that any action it authorizes, funds, or carries out
is not likely to jeopardize the continued existence of any endangered or threatened
species or result in the destruction or adverse modification of designated critical habitat.
To ensure ESA compliance for the issuance of IHAs, NMFS consults internally whenever
we propose to authorize take for endangered or threatened species.
NMFS' Office of Protected Resources is proposing to authorize take of four
species of marine mammals that are listed under the ESA (i.e., North Atlantic right
whale, fin whale, sei whale, and sperm whale) and has determined these activities fall
within the scope of activities analyzed in the NMFS GARFO programmatic consultation
regarding geophysical surveys along the U.S. Atlantic coast in the 3 Atlantic renewable
energy regions (completed June 29, 2021; revised September 2021).
Proposed Renewal IHA and Request for Public Comment

As a result of these preliminary determinations, NMFS proposes to issue a
renewal IHA to IWO for conducting marine site characterization with HRG surveys off
the coast of New York and New Jersey in the New York Bight from July 31, 2024,
through July 30, 2025, provided the previously described mitigation, monitoring, and
reporting requirements are incorporated. A draft of the proposed and final initial IHA
can be found at https://www.fisheries.noaa.gov/permit/incidental-take-authorizationsunder-marine-mammal-protection-act. We request comment on our analyses, the
proposed renewal IHA, and any other aspect of this notice. Please include with your
comments any supporting data or literature citations to help inform our final decision on
the request for MMPA authorization.
