SUPPLEMENTARY INFORMATION:
Background
The activities described in Ocean Wind II's request, the overall
survey duration, the project location, and the acoustic sources
proposed for use are identical to what was previously analyzed in
support of the IHA issued by NMFS to Ocean Wind II for 2022 site
characterization surveys (2022 IHA) (87 FR 14823, March 16, 2022; 87 FR
30453, May 19, 2022). All proposed mitigation, monitoring, and
reporting requirements remain the same. While Ocean Wind II's planned
activity would qualify for renewal of the 2022 IHA, due to the
availability of updated marine mammal density data (<a href="https://seamap.env">https://seamap.env</a>
.duke.edu/models/Duke/EC/), which NMFS has determined represents the
best available scientific data, NMFS has determined it appropriate to
provide a 30-day period for the public to comment on this proposed
action.
Pursuant to the Marine Mammal Protection Act (MMPA), NMFS is
requesting comments on its proposal to issue an IHA to allow Ocean Wind
II to incidentally take marine mammals
[[Page 38492]]
during the specified activities. NMFS is also requesting comments on a
possible one-year Renewal IHA that could be issued under certain
circumstances and if all requirements are met, as described in Request
for Public Comments at the end of this notice. NMFS will consider
public comments prior to making any final decision on the issuance of
the requested MMPA authorization and agency responses will be
summarized in the final notice of our decision.
The activities described in Ocean Wind II's request, the overall
survey duration, the project location, and the acoustic sources
proposed for use are identical to what was previously analyzed in
support of the Incidental Harassment Authorization (IHA issued by NMFS
to Ocean Wind II for 2022 site characterization surveys (2022 IHA) (87
FR 14823, March 16, 2022). All proposed mitigation, monitoring, and
reporting requirements remain the same. While Ocean Wind II's planned
activity would qualify for renewal of the 2022 IHA, due to the
availability of updated marine mammal density data (<a href="https://seamap.env">https://seamap.env</a>.duke.edu/models/Duke/ EC/), which NMFS has determined
represents the best available scientific data, NMFS has determined it
appropriate to provide a 30-day period for the public to comment on
this proposed action.
NMFS is requesting comments on its proposal to issue an IHA to
incidentally take marine mammals during the specified activities. NMFS
is also requesting comments on a possible one-year Renewal IHA that
could be issued under certain circumstances and if all requirements are
met, as described in Request for Public Comments at the end of this
notice. NMFS will consider public comments prior to making any final
decision on the issuance of the requested MMPA authorizations and
agency responses will be summarized in the final notice of our
decision.
The 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 issued or, if the taking is limited to harassment, a notice of a
proposed incidental take authorization may be provided to the public
for review.
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). Further, 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 in shorthand as
``mitigation''); and requirements pertaining to the mitigation,
monitoring and reporting of such takings are set forth.
National Environmental Policy Act
To comply with the National Environmental Policy Act of 1969 (NEPA;
42 U.S.C. 4321 et seq.) and NOAA Administrative Order (NAO) 216-6A,
NMFS must review our proposed action (i.e., the issuance of an IHA)
with respect to potential impacts on the human environment. This action
is consistent with categories of activities identified in Categorical
Exclusion B4 (IHAs 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 has preliminarily determined
that the issuance of the proposed IHA qualifies to be categorically
excluded from further NEPA review.
We will review all comments submitted in response to this
notification prior to concluding our NEPA process or making a final
decision on the IHA request.
Summary of Request
On February 14, 2022, NMFS received a request from Ocean Wind II
for an IHA to take marine mammals incidental to high-resolution
geophysical (HRG) marine site characterization surveys offshore of New
Jersey in the area of BOEM Commercial Lease of Submerged Lands for
Renewable Energy Development on the OCS-A 0532 (Lease Area) and
associated ECR area. Following NMFS' review of the application, Ocean
Wind II submitted a revised request on April 28, 2023. The application
(the 2023 request) was deemed adequate and complete on April 28, 2023.
Ocean Wind II's request is for take of 16 species (comprising 17
stocks) of marine mammals, including 14 cetacean and two pinniped
(seal) species, by Level B harassment only. Neither Ocean Wind II nor
NMFS expects serious injury or mortality to result from this activity
and, therefore, an IHA is appropriate. Take by Level A harassment
(injury) is considered unlikely, even absent mitigation, based on the
characteristics of the signals produced by the acoustic sources planned
for use.
On October 1, 2021, NMFS received a request from Ocean Wind II for
an IHA to take marine mammals incidental to HRG marine site
characterization surveys offshore of New Jersey in the area of BOEM
Commercial Lease of Submerged Lands for Renewable Energy Development on
the OCS Lease Area OCS-A 0532 (Lease Area) and associated ECR area.
Ocean Wind II requested authorization to take small numbers of 16
species (comprising 17 stocks) of marine mammals by Level B harassment
only. NMFS published a notice of the proposed IHA in the Federal
Register on March 16, 2022 (87 FR 14823). After a 30-day public comment
period and consideration of all public comments received, we
subsequently issued the IHA on May 19, 2022 (87 FR 30453), which is
effective from May 10, 2022 through May 9, 2023.
Ocean Wind II completed the survey work under the 2022 IHA and
submitted a final monitoring report, which demonstrates that they
conducted the required marine mammal mitigation and monitoring, and did
not exceed the authorized levels of take under the previous IHA issued
for surveys offshore of New Jersey (see 87 FR 30452, May 19, 2022).
These monitoring results are available to the public on our website:
<a href="https://www.fisheries.noaa.gov/action/incidental-take-authorization-ocean-wind-ii-llc-marine-site-characterization-surveys-new">https://www.fisheries.noaa.gov/action/incidental-take-authorization-ocean-wind-ii-llc-marine-site-characterization-surveys-new</a>.
The 2023 IHA request is identical to the 2022 IHA request. However,
NMFS has determined a renewal of the 2022 IHA is not appropriate
because Duke University's Marine Geospatial Ecology Laboratory released
updated marine mammal density information (June 20, 2022) for all
species in the project area (<a href="https://seamap.env">https://seamap.env</a>.duke.edu/models/Duke/
EC/) after issuance of the 2022 IHA. In evaluating the 2023 request,
which incorporates the updated density information, and to the extent
deemed appropriate, NMFS relies on the information presented in notices
associated with issuance of the 2022 IHA (87 FR 14823, March 16, 2022;
87 FR 30453, May 19, 2022).
[[Page 38493]]
Description of the Proposed Activity and Anticipated Impacts
Overview
Ocean Wind II proposes to conduct HRG marine site characterization
surveys in the BOEM Lease Area OCS-A 0532 and along potential submarine
ECRs to landfall locations in New Jersey. The purpose of the proposed
surveys is to obtain an assessment of seabed (geophysical,
geotechnical, and geohazard), ecological, and archeological conditions
within the footprint of a planned offshore wind facility development
area. Surveys are also conducted to support engineering design and to
map unexploded ordnance. Survey equipment would be deployed from
multiple vessels or remotely operated vehicles (ROVs) during site
characterization activities in the project area; however, only one
vessel would operate at a time in the lease area and ECR area (two
vessels total). During survey effort, the vessel would operate at a
maximum speed of 4 knots (4.6 miles or 7.4 km per hour). Underwater
sound resulting from Ocean Wind II's activities has the potential to
result in incidental take of marine mammals in the form of Level B
harassment.
Dates and Duration
The proposed activity is estimated to require 275 survey days, and
is expected to be carried out over the course of the one-year period of
effectiveness beginning from the date of issuance of this IHA. A
``survey day'' is defined as a 24-hour (hr) activity period in which
active HRG acoustic sources are used. This schedule is inclusive of any
inclement weather downtime and crew transfers. The number of survey
days was calculated as the number of days needed to reach the overall
level of effort required to meet survey objectives assuming any single
vessel covers, on average, 70 km (129.6 miles) of survey trackline per
24 hours of operations.
Specific Geographic Region
Ocean Wind II's proposed activities would occur in the Northwest
Atlantic Ocean within Federal and state waters offshore of New Jersey
in BOEM Lease Area OCS-A 0532 and associated ECR area to landfall
locations in New Jersey (Figure 1). As compared to the 2022 IHA (87 FR
14823, March 16, 2022; 87 FR 30453, May 19, 2022), Ocean Wind II
revised their project area map (Figure 1) to be more representative of
the actual area in which HRG surveys would occur. The revised project
area description is based on updated information received from the
Ocean Wind II site investigation team. The Lease Area is approximately
343.8 square kilometers (km\2\) and is within the New Jersey Wind
Energy Area (WEA) of BOEM's Mid-Atlantic planning area. The total
survey area depicted in Figure 1 (including the Lease Area and
potential ECRs) encompasses 3,801 km\2\. Water depths in the Lease Area
range from 14 meters (m) (45.9 feet (ft)) to 38 m (124.6 ft), and the
potential ECRs extend from the shoreline to approximately 30 m (98.4
ft) depth.

Detailed Description of the Action
A detailed description of the proposed survey activities can be
found in the previous Federal Register notices (87 FR 14823, March 16,
2022; 87 FR 30453, May 19, 2022) and supplementary documents, available
online at: <a href="https://www.fisheries.noaa.gov/action/incidental-take-authorization-ocean-wind-ii-llc-marine-site-characterization-surveys-new">https://www.fisheries.noaa.gov/action/incidental-take-authorization-ocean-wind-ii-llc-marine-site-characterization-surveys-new</a>. The specific geographic region (except for the abovementioned
slight revisions made based on information received from the Ocean Wind
II site investigation team); duration (275 total survey days); and
nature of the activities, including the types of HRG equipment planned
for use (boomers, sparkers, and non-parametric sub-bottom profilers);
daily trackline distances (70 km per day); and number of survey vessels
(one vessel operating at a time in the Lease Area and ECR Area, for a
total of two vessels) are identical or nearly identical to those
described in those previous notices.
Description of Marine Mammals
A description of the marine mammals in the proposed survey area can
be
[[Page 38495]]
found in the previous documents and notices for the 2022 IHA (87 FR
14823, March 16, 2022; 87 FR 30453, May 19, 2022), which remains
applicable to this proposed IHA. NMFS reviewed the most recent draft
Stock Assessment Reports (SARs, found on NMFS' website at <a href="https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-stock-assessments">https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-stock-assessments</a>), up-to-date information on relevant Unusual
Mortality Events (UMEs; <a href="https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-unusual-mortality-events">https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-unusual-mortality-events</a>), and recent
scientific literature and determined that no new information affects
our original analysis of impacts under the 2022 IHA.
NMFS notes that, since issuance of the 2022 IHA, a new SAR is
available for the North Atlantic right whale (NARW). Estimated
abundance for the species declined from 368 to 338. However, this
change does not affect our analysis of impacts, as described under the
2022 IHA. Additionally, on August 1, 2022, NMFS announced proposed
changes to the existing NARW vessel speed regulations to further reduce
the likelihood of mortalities and serious injuries to endangered NARWs
from vessel collisions, which are a leading cause of the species'
decline and a primary factor in an ongoing Unusual Mortality Event (87
FR 46921). Should a final vessel speed rule be issued and become
effective during the effective period of this IHA (or any other MMPA
incidental take authorization), the authorization holder would be
required to comply with any and all applicable requirements contained
within the final rule. Specifically, where measures in any final vessel
speed rule are more protective or restrictive than those in this or any
other MMPA authorization, authorization holders would be required to
comply with the requirements of the rule. Alternatively, where measures
in this or any other MMPA authorization are more restrictive or
protective than those in any final vessel speed rule, the measures in
the MMPA authorization would remain in place. The responsibility to
comply with the applicable requirements of any vessel speed rule would
become effective immediately upon the effective date of any final
vessel speed rule and, when notice is published of the effective date,
NMFS would also notify Ocean Wind II if the measures in the speed rule
were to supersede any of the measures in the MMPA authorization such
that they were no longer applicable
Potential Effects on Marine Mammals and Their Habitat
A description of the potential effects of the specified activities
on marine mammals and their habitat can be found in the documents
supporting the 2022 IHA (87 87 FR 14823, March 16, 2022; 87 FR 30453,
May 19, 2022). At present, there is no new information on potential
effects that would influence our analysis.
Estimated Take
A detailed description of the methods used to estimate take
anticipated to occur incidental to the project is found in the previous
Federal Register notices (87 FR 14823, March 16, 2022; 87 FR 30453, May
19, 2022). The methods of estimating take are identical to those used
in the 2022 IHA. Ocean Wind II updated the marine mammal densities
based on new information (Roberts et al., 2016; Roberts and Halpin,
2022), available online at: <a href="https://seamap.env">https://seamap.env</a>.duke.edu/models/Duke/
EC/. We refer the reader to Table 2 in Ocean Wind II's 2023 IHA request
for the specific density values used in the analysis. The IHA request
is available online at: <a href="https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-other-energy-activities-renewable">https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-other-energy-activities-renewable</a>.
The take that NMFS proposes to authorize can be found in Table 2,
which presents the results of Ocean Wind II's density-based
calculations for the survey area. For comparative purposes, we have
provided the 2022 IHA authorized Level B harassment take (87 FR 30453,
May 19, 2022). NMFS notes that take by Level A harassment was not
requested, nor does NMFS anticipate that it could occur. Therefore,
NMFS has not proposed to authorize any take by Level A harassment.
Mortality or serious injury is neither anticipated to occur nor
proposed for authorization.

\1\ Parentheses denote proposed take authorization where different from calculated take estimates. Increases from calculated values are based on average
group size for the following species: sei whale and pilot whales, Kenney and Vigness-Raposa, 2010; sperm whale and Risso's dolphin, Barkaszi and
Kelly, 2018; Atlantic white-sided dolphins, NMFS 2022a; and Atlantic spotted dolphins, NMFS 2022b.The amount of proposed common dolphin take is based
on the number of individuals observed in previous HRG surveys in the area, and is identical to the amount of take authorized in the 2022 IHA.
\2\ At this time, Ocean Wind II is not able to identify how much work would occur inshore and offshore of the 20 m isobaths, a common delineation
between offshore and coastal bottlenose dolphin stocks. Because Roberts et al. does not provide density estimates for individual stocks of common
bottlenose dolphins, the take presented here is the total estimated take for both stocks. Although unlikely, for our analysis, we assume all takes
could be allocated to either stock.
[[Page 38496]]
\3\ Roberts (2018) only provides density estimates for pilot whales as a guild. Given the project's location, NMFS assumes that all take will be of long-
finned pilot whales.
\4\ Roberts (2018) only provides density estimates for seals without differentiating by species. Harbor seals and gray seals are assumed to occur
equally in the survey area; therefore, density values were split evenly between the two species, i.e., total estimated take for ``seals'' is 24.
\5\ NMFS' stock abundance estimate (and associated PBR value) applies to U.S. population only. Total stock abundance (including animals in Canada) is
approximately 451,600.
Description of Proposed Mitigation, Monitoring and Reporting Measures
The mitigation, monitoring, and reporting measures proposed here
are identical to those included in the Federal Register notice
announcing the final 2022 IHA and the discussion of the least
practicable adverse impact included in that document remains accurate.
As described in the previous Federal Register notices (87 FR 14823,
March 16, 2022; 87 FR 30453, May 19, 2022), NMFS determined that
issuance of the 2022 IHA to Ocean Wind II was within the scope of the
NOAA Fisheries Greater Atlantic Regional Office (GARFO) programmatic
consultation regarding geophysical surveys along the U.S. Atlantic
coast in the three Atlantic Renewable Energy Regions (NOAA GARFO, 2021;
<a href="https://www.fisheries.noaa.gov/new-england-mid-atlantic/consultations/section-7-take-reporting-programmatics-greater-atlantic#offshore-wind-site-assessment-and-site-characterization-activities-programmatic-consultation">https://www.fisheries.noaa.gov/new-england-mid-atlantic/consultations/section-7-take-reporting-programmatics-greater-atlantic#offshore-wind-site-assessment-and-site-characterization-activities-programmatic-consultation</a>). NMFS similarly concludes that the currently proposed
survey activities are within scope of the consultation, and thus will
require adherence to the relevant Project Design Criteria (PDC)
(specifically PDCs 4, 5, and 7).
Establishment of Shutdown Zones (SZ)--Marine mammal SZs must be
established around the HRG survey equipment and monitored by NMFS-
approved protected species observers (PSO) during HRG surveys as
follows:
<bullet> 500-m SZ for North Atlantic right whales during use of
specified acoustic sources (impulsive: sparkers and boomers; non-
impulsive: non-parametric sub-bottom profilers); and,
<bullet> 100-m SZ for all other marine mammals (excluding North
Atlantic right whales) during operation of the sparker and boomer. The
only exception for this is for pinnipeds (seals) and small delphinids
(i.e., those from the genera Delphinus, Lagenorhynchus, Stenella or
Tursiops).
If a marine mammal is detected approaching or entering the SZs
during the HRG survey, the vessel operator would adhere to the shutdown
procedures described below to minimize noise impacts on the animals.
During use of acoustic sources with the potential to result in marine
mammal harassment (sparkers, boomers, and non-parametric sub-bottom
profilers; i.e., anytime the acoustic source is active, including ramp-
up), occurrences of marine mammals within the monitoring zone (but
outside the SZs) must be communicated to the vessel operator to prepare
for potential shutdown of the acoustic source.
<bullet> Visual Monitoring--Monitoring must be conducted by
qualified PSOs who are trained biologists, with minimum qualifications
described in the Federal Register notices for the 2022 project (87 FR
14823, March 16, 2022; 87 FR 30453, May 19, 2022). Ocean Wind II must
have one PSO on duty during the day and a minimum of two NMFS-approved
PSOs must be on duty and conducting visual observations when HRG
equipment is in use at night. Visual monitoring must begin no less than
30 minutes prior to ramp-up of HRG equipment and continue until 30
minutes after use of the acoustic source. PSOs must establish and
monitor the applicable clearance zones, SZs, and vessel separation
distances as described in the 2022 IHA (87 FR 30453, May 19, 2022).
PSOs must coordinate to ensure 360-degree visual coverage around the
vessel from the most appropriate observation posts, and must conduct
observations while free from distractions and in a consistent,
systematic, and diligent manner. PSOs are required to estimate
distances to observed marine mammals. It is the responsibility of the
Lead PSO on duty to communicate the presence of marine mammals as well
as to communicate action(s) that are necessary to ensure mitigation and
monitoring requirements are implemented as appropriate.
Pre-Start Clearance--Marine mammal clearance zones (CZs) must be
established around the HRG survey equipment and monitored by NMFS-
approved protected species observers (PSO) prior to use of boomers,
sparkers, and non-parametric sib-bottom profilers as follow:
<bullet> 500-m CZ for all ESA-listed species; and,
<bullet> 100-m CZ for all other marine mammals.
Prior to initiating HRG survey activities, Ocean Wind II must
implement a 30-minute pre-start clearance period. The operator must
notify a designated PSO of the planned start of ramp-up where the
notification time should not be less than 60 minutes prior to the
planned ramp-up to allow the PSOs to monitor the CZs for 30 minutes
prior to the initiation of ramp-up. Prior to ramp-up beginning, Ocean
Wind II must receive confirmation from the PSO that the CZs are clear
prior to preceding. Any PSO on duty has the authority to delay the
start of survey operations if a marine mammal is detected within the
applicable pre-start clearance zones.
During this 30-minute period, the entire CZ must be visible. The
exception to this would be in situations where ramp-up must occur
during periods of poor visibility (inclusive of nighttime) as long as
appropriate visual monitoring has occurred with no detections of marine
mammals in 30 minutes prior to the beginning of ramp-up. Acoustic
source activation must only occur at night where operational planning
cannot reasonably avoid such circumstances.
If a marine mammal is observed within the relevant CZs during the
pre-start clearance period, initiation of HRG survey equipment must not
begin until the animal(s) has been observed exiting the respective CZ,
or, until an additional period has elapsed with no further sighting
(i.e., minimum 15 minutes for small odontocetes and seals; 30 minutes
for all other species). The pre-start clearance requirement includes
small delphinids. PSOs must also continue to monitor the zone for 30
minutes after survey equipment is shut down or survey activity has
concluded.
<bullet> Ramp-Up of Survey Equipment--When technically feasible, a
ramp-up procedure must be used for geophysical survey equipment capable
of adjusting energy levels at the start or re-start of survey
activities. The ramp-up procedure must be used at the beginning of HRG
survey activities in order to provide additional protection to marine
mammals near the project area by allowing them to detect the presence
of the survey and vacate the area prior to the commencement of survey
equipment operation at full power. Ramp-up of the survey equipment must
not begin until the relevant SZs has been cleared by the PSOs, as
described above. HRG equipment operators must ramp up acoustic sources
to half power for 5 minutes and then proceed to full power. If any
marine mammals are detected within the SZs prior to or during ramp-up,
the HRG equipment must be shut down (as described below).
[[Page 38497]]
<bullet> Shutdown Procedures--If an HRG source is active and a
marine mammal is observed within or entering a relevant SZ (as
described above), an immediate shutdown of the HRG survey equipment is
required. When shutdown is called for by a PSO, the acoustic source
must be immediately deactivated and any dispute resolved only following
deactivation. Any PSO on duty has the authority to delay the start of
survey operations or to call for shutdown of the acoustic source if a
marine mammal is detected within the applicable SZ. The vessel operator
must establish and maintain clear lines of communication directly
between PSOs on duty and crew controlling the HRG source(s) to ensure
that shutdown commands are conveyed swiftly while allowing PSOs to
maintain watch. Subsequent restart of the HRG equipment may only occur
after the marine mammal has been observed exiting the relevant SZ, or,
until an additional period has elapsed with no further sighting of the
animal within the relevant SZ.
Upon implementation of shutdown, the HRG source may be reactivated
after the marine mammal that triggered the shutdown has been observed
exiting the applicable SZ or, following a clearance period of 15
minutes for small odontocetes (i.e., harbor porpoise) and 30 minutes
for all other species with no further observation of the marine
mammal(s) within the relevant SZ. If the HRG equipment is shut down for
brief periods (i.e., less than 30 minutes) for reasons other than
mitigation (e.g., mechanical or electronic failure) the equipment may
be re-activated as soon as is practicable at full operational level,
without 30 minutes of pre-clearance, only if PSOs have maintained
constant visual observation during the shutdown and no visual
detections of marine mammals occurred within the applicable SZs during
that time. For a shutdown of 30 minutes or longer, or if visual
observation was not continued diligently during the pause, pre-
clearance observation is required, as described above.
The shutdown requirement is waived for pinnipeds (seals) and
certain genera of small delphinids (i.e., Delphinus, Lagenorhynchus,
Stenella, or Tursiops) under certain circumstances. If a delphinid(s)
from these genera is visually detected within the SZ, shutdown would
not be required. If there is uncertainty regarding identification of a
marine mammal species (i.e., whether the observed marine mammal(s)
belongs to one of the delphinid genera for which shutdown is waived),
PSOs must use best professional judgment in making the decision to call
for a shutdown.
If a species for which authorization has not been granted, or a
species for which authorization has been granted but the authorized
number of takes have been met, approaches or is observed within the
area encompassing the Level B harassment isopleth (141 m), shutdown
must occur.
<bullet> Vessel Strike Avoidance--Ocean Wind II must comply with
vessel strike avoidance measures as described in the Federal Register
notice for the 2022 IHA (87 FR 30453, May 19, 2022). This includes
speed restrictions (10 knots or less) when mother/calf pairs, pods, or
large assemblages of cetaceans are spotted near a vessel; species-
specific vessel separation distances; appropriate vessel actions when a
marine mammal is sighted (e.g., avoid excessive speed, remain parallel
to animal's course, etc.); and monitoring of the NMFS North Atlantic
Right Whale reporting system and Whale Alert daily.
<bullet> Seasonal Operating Requirements--Ocean Wind II will
conduct HRG survey activities in the vicinity of a North Atlantic right
whale Mid-Atlantic seasonal management area (SMA). Activities must
comply with the seasonal mandatory speed restriction period for this
SMA (November 1 through April 30) for any survey work or transit within
this area.
Throughout all phases of the survey activities, Ocean Wind II must
monitor NOAA Fisheries North Atlantic right whale reporting systems for
the establishment of a dynamic management area (DMA). If NMFS
establishes a DMA in the surrounding area, including the project area
or export cable routes being surveyed, Ocean Wind II is required to
abide by the 10-knot speed restriction.
<bullet> Training--Project-specific training is required for all
vessel crew prior to the start of survey activities.
<bullet> Reporting--PSOs must record specific information as
described in the Federal Register notice of the issuance of the 2022
IHA (87 FR 30453, May 19, 2022). Within 90 days after completion of
survey activities, Ocean Wind II must provide NMFS with a monitoring
report, which must include summaries of recorded takes and estimates of
the number of marine mammals that may have been harassed.
In the event of a ship strike or discovery of an injured or dead
marine mammal, Ocean Wind II must report the incident to the Office of
Protected Resources (OPR), NMFS and to the New England/Mid-Atlantic
Regional Stranding Coordinator as soon as feasible. The report must
include the information listed in the Federal Register notice of the
issuance of the initial IHA (87 FR 30453, May 19, 2022).
Preliminary Determinations
Ocean Wind II's HRG survey activities are unchanged from those
analyzed in support of the 2022 IHA. The effects of the activity,
taking into consideration the proposed mitigation and related
monitoring measures, remain unchanged from those evaluated in support
of the 2022 IHA, regardless of the minor increases in estimated take
numbers for some marine mammal species and/or stocks. NMFS expects that
all potential takes would be short-term Level B behavioral harassment
in the form of temporary avoidance of the area or decreased foraging
(if such activity was occurring), reactions that are considered to be
of low severity and with no lasting biological consequences (e.g.,
Southall et al., 2007). In addition to being temporary, the maximum
expected harassment zone around a survey vessel is 141 m. Although this
distance is assumed for all survey activity evaluated here and in
estimating take numbers proposed for authorization, in reality, much of
the survey activity would involve use of non-impulsive acoustic sources
with a reduced acoustic harassment zone of up to 48 m, producing
expected effects of particularly low severity. Therefore, the
ensonified area surrounding each vessel is relatively small compared to
the overall distribution of the animals in the area and the available
habitat. Feeding behavior is not likely to be significantly impacted as
prey species are mobile and are broadly distributed throughout the
survey area; therefore, marine mammals that may be temporarily
displaced during survey activities are expected to be able to resume
foraging once they have moved away from areas with disturbing levels of
underwater noise. Because of the temporary nature of the disturbance
and the availability of similar habitat and resources in the
surrounding area, the impacts to marine mammals and the food sources
that they utilize are not expected to cause significant or long-term
consequences for individual marine mammals or their populations. Even
considering the increased estimated take for some species, the impacts
of these lower severity exposures are not expected to accrue to a
degree that the fitness of any individuals would be impacted and,
therefore, no impacts on the annual rates of recruitment or survival
would result.
As previously discussed in the 2022 IHA (87 FR 30453, May 19,
2022), impacts from the survey are expected to
[[Page 38498]]
be localized to the specific area of activity and only during periods
when Ocean Wind II's acoustic sources are active. There are no
rookeries, mating or calving grounds, or any feeding areas known to be
biologically important to marine mammals within the proposed survey
area. There is no designated critical habitat for any ESA-listed marine
mammals in the survey area.
As noted for the 2022 IHA (87 FR 30453, May 19, 2022), the survey
area overlaps a migratory corridor biologically important area (BIA)
for NARWs. Because the survey activities are temporary and the spatial
extent of sound produced by the survey would be very small relative to
the spatial extent of the available migratory habitat in the BIA
(269,448 km\2\), NMFS does not expect NARW migration to be impacted by
the survey. Given the relatively small size of the ensonified area, it
is unlikely that prey availability would be adversely affected by HRG
survey operations. Required vessel strike avoidance measures will also
decrease risk of ship strike during migration; no ship strike is
expected to occur during Ocean Wind II's planned activities.
Additionally, Ocean Wind II requested and NMFS proposes to authorize
only two takes by Level B harassment of NARWs. This amount is reduced
from the 11 Level B harassment takes authorized in the 2022 IHA due to
the revised Duke University density data (Roberts and Halpin, 2022).
HRG survey operations are required to maintain a 500-m SZ, and shutdown
if a NARW is sighted at or within the SZ. The 500-m SZ for NARWs is
conservative, considering the Level B harassment isopleth for the most
impactful acoustic source (i.e., sparker) is estimated to be 141 m, and
thereby minimizes the potential for behavioral harassment of this
species. As noted previously, Level A harassment is not expected due to
the small PTS zones associated with HRG equipment types proposed for
use. NMFS does not anticipate NARWs takes that would result from Ocean
Wind II's activities would impact annual rates of recruitment or
survival. Thus, any takes that occur would not result in population
level impacts.
We also note that our findings for other species with active UMEs
that were previously described for the 2022 IHA remain applicable to
this project. Therefore, in conclusion, there is no new information
suggesting that our analysis or findings should change.
Based on the information contained here and in the referenced
documents, NMFS has preliminarily 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 proposed
authorized takes will have a negligible impact on the affected marine
mammal species or stocks; (3) the proposed authorized takes represent
small numbers of marine mammals relative to the affected stock
abundances; (4) Ocean Wind II'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 (ESA)
Section 7(a)(2) of the Endangered Species Act of 1973 (ESA; 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 OPR consults internally whenever we propose to authorize take for
endangered or threatened species.
NMFS is proposing to authorize the incidental take of four species
of marine mammals which are listed under the ESA, including the North
Atlantic right, fin, sei, and sperm whale, and has determined that this
activity falls within the scope of activities analyzed in NMFS GARFO's
programmatic consultation regarding geophysical surveys along the U.S.
Atlantic coast in the three Atlantic Renewable Energy Regions
(completed June 29, 2021; revised September 2021).
Proposed Authorization
As a result of these preliminary determinations, NMFS proposes to
issue an IHA to Ocean Wind II for conducting high-resolution
geophysical site characterization surveys offshore of New Jersey for a
period of one year, provided the previously mentioned mitigation,
monitoring, and reporting requirements are incorporated. A draft of the
proposed IHA can be found at <a href="https://www.fisheries.noaa.gov/permit/incidental-take-authorizations-under-marine-mammal-protection-act">https://www.fisheries.noaa.gov/permit/incidental-take-authorizations-under-marine-mammal-protection-act</a>.
Request for Public Comments
We request comment on our analyses (included in both this document
and the referenced documents supporting the 2022 IHA (ITA application;
issued IHA; and Federal Register notices including 87 FR 4200, January
27, 2022; 87 FR 24103, April 22, 2022; 87 FR 26726, May 5, 2022)), the
proposed authorization, and any other aspect of this notice of proposed
IHA for the proposed site characterization surveys. We also request
comment on the potential for renewal of this proposed IHA as described
in the paragraph below. Please include with your comments any
supporting data or literature citations to help inform our final
decision on the request for MMPA authorization.
On a case-by-case basis, NMFS may issue a one-time, one-year
renewal 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, or nearly identical, activities as described in the
Description of the Proposed Activity and Anticipated Impacts section of
this notice is planned or (2) the activities as described in the
Description of the Proposed Activity and Anticipated Impacts section of
this 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, provided
all of the following conditions are met:
<bullet> 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 one year from
expiration of the initial IHA);
<bullet> The request for renewal must include the following:
(1) 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
(2) 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
<bullet> 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.
