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 proposed or, if the taking is limited to 
harassment, a notice of a proposed incidental take authorization is 
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 here as ``mitigation 
measures''). Monitoring and reporting of such takings are also 
required. The meaning of key terms such as ``take,'' ``harassment,'' 
and ``negligible impact'' can be found in section 3 of the MMPA (16 
U.S.C. 1362) and the agency's regulations at 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 authorization, 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 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 Detailed Description of Specified Activities section 
of the initial IHA issuance notice is planned or (2) the activities as 
described in the Detailed Description of Specified Activities 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 initial 
IHA issuance, 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

[[Page 64767]]

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).
     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.
    (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: www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals.

History of Request

    On May 27, 2020, NMFS issued an IHA to the Navy to take marine 
mammals incidental to in-water construction associated with the 
Floating Dry Dock Project at Naval Base San Diego in San Diego, 
California (85 FR 33129; June 1, 2020), effective from September 15, 
2020 through September 14, 2021 (hereafter referred to as the 2020 
IHA). On July 12, 2021, the Navy informed NMFS that the project had 
been delayed and none of the work identified in the initial IHA had 
occurred. The Navy requested an identical IHA be reissued with the 
effective dates one year later, in order to conduct the construction 
work that was analyzed and authorized through the previously issued 
IHA. On July 21, 2021, NMFS reissued the IHA to the Navy (86 FR 40468; 
July 28, 2021), effective from September 15, 2021 through September 14, 
2022 (hereafter referred to as the initial IHA).
    On July 15, 2022, the Navy notified NMFS that the project had been 
further delayed and none of the work identified in the initial IHA had 
occurred. In addition, the Navy had made minor changes to the project 
design plan, which would result in fewer proposed days of in-water 
construction than what was planned and analyzed in the 2020 IHA and 
initial IHA. As described in the Description of the Specified 
Activities and Anticipated Impacts section below, the activities for 
which incidental take is requested are nearly identical to those 
covered in the initial IHA. In order to consider an IHA renewal, NMFS 
requires the applicant provide a preliminary monitoring report which 
confirms that the applicant has implemented the required mitigation and 
monitoring, and which also shows that no impacts of a scale or nature 
not previously analyzed or authorized have occurred as a result of the 
activities conducted. However, as no construction activities have been 
conducted, the Navy has no monitoring results to report. NMFS has 
determined that the minor changes to the Navy's proposed pile driving 
activities would not affect the previous analyses, including the 
mitigation, monitoring, and reporting requirements, or take estimates 
(with the exception of reducing the amount of estimated take due to 
fewer days of construction). The notice of the proposed renewal IHA was 
published on September 20, 2022 (87 FR 57473).

Description of the Specified Activities and Anticipated Impacts

    The Navy plans to construct a floating dry dock and associated 
pier-side access at Naval Base San Diego in the south-central portion 
of San Diego Bay. The floating dry dock is needed to ensure the Base's 
capability to conduct berth-side repair and maintenance of vessels. 
Implementation of the project requires installation of two mooring 
dolphins, including vertical and angled structural piles, as well as 
fender piles, installation of a concrete ramp wharf and vehicle bridge, 
and dredging at the proposed floating dry dock location. The planned 
in-water construction covered in the initial IHA included installation 
of a maximum of 56 24-inch concrete piles using impact pile driving and 
high-pressure water jetting and a maximum of 10 24-inch steel pipe 
piles using impact and vibratory pile driving. The Navy's revised 
construction design plan includes fewer 24-inch octagonal concrete 
piles and has eliminated all 24-inch steel pipe piles, while adding 18-
inch square concrete piles, 18-inch octagonal concrete piles, and 14-
inch steel H-piles (Table 1).
    The anticipated impacts of the Navy's planned activities are 
identical to those described in the initial IHA. As in the initial IHA, 
NMFS anticipates that only the U.S. stock of California sea lions 
(Zalophus californianus) may be taken by Level B harassment incidental 
to underwater noise resulting from in-water construction associated 
with the proposed activities.

for reissued IHA, and request for IHA renewal (available at 
www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-construction-activities).

Detailed Description of the Activity

    The Navy plans to construct a floating dry dock and associated 
pier-side access in the south-central portion of San Diego Bay. The 
floating dry dock is needed in order to address current and projected 
shortfall of dry dock space required for maintenance of the Pacific 
Fleet, and ensure the Naval Base San Diego's capability to conduct 
berth-side repair and maintenance of vessels. The planned activities 
will allow for the emplacement and operation of a floating dry dock and 
associated pier-side access at Marine Group Boat Works (MGBW) 
Commercial Out Lease (COL) in the southern edge of Naval Base San 
Diego.
    Up to 50 days of in-water pile driving were planned to occur under 
the initial IHA, which included installation of two mooring dolphins, 
including vertical and angled structural piles, as well as fender 
piles, and installation of a concrete ramp wharf and vehicle bridge. 
Two mooring dolphins would be located forward and aft of the proposed 
dry dock. The mooring dolphins would each be supported by up to 16 
vertical 24-inch octagonal concrete piles (32 total) installed using 
impact pile driving and high-pressure water jetting. The aft mooring 
dolphin would also require approximately two 24-inch angled steel pipe 
piles. Up to eight additional 24-inch steel pipe piles are anticipated 
to be required for the forward and aft mooring dolphins. Cast-in-place 
reinforced concrete caps, 9.1 by 9.1 meter (m; 30 by 30 feet (ft)), 
would be

[[Page 64768]]

installed at each mooring dolphin location. Grippers would be secured 
to the dolphins' concrete pile caps and used to hold the floating dry 
dock in position. Construction materials would be delivered by truck 
and the piles would be installed using a floating crane and an impact 
or vibratory pile driver aided by jetting methods. Fender piles 
associated with the aft mooring dolphin would consist of two steel pipe 
piles, 24-inches in diameter or less. All steel pipe piles would 
initially be installed using vibratory pile driving, followed by the 
use of an impact pile driver. The concrete ramp wharf and vehicle 
bridge would be supported by 24 24-inch octagonal concrete piles 
installed using vibratory pile driving and high-pressure water jetting.
    The modified construction design plan that will occur under the 
renewal IHA includes the installation of a total of 55 concrete piles 
and 10 steel H-piles. Five concrete piles will also be removed (via 
dead pull with no vibratory hammer required) and 12 steel template H-
piles will be installed and subsequently removed using a vibratory 
hammer. A total of 77 piles will be installed (65 permanent, 12 
temporary) which is greater than the total number of piles planned to 
be installed under the initial IHA (Table 1); however, the revised 
construction plan includes a reduction in diameter for the majority of 
piles as assessed in the initial IHA. Therefore, the modified 
construction plan is reasonably similar to the plan associated with the 
initial IHA. In addition, the Navy had estimated up to 50 days of in-
water work would be required to complete the planned construction in 
the initial IHA, and the revised construction design will require only 
40 days of construction, beginning in April 2023.

    A detailed description of the construction activities for which 
authorization of take is authorized here may be found in the Federal 
Register notice of proposed IHA for the 2020 IHA (85 FR 21179; April 
16, 2020). With the exception of some reduced pile sizes and change 
from steel pipe piles to steel H-piles, the methods of pile driving 
(i.e., vibratory and impact hammers, high-pressure water jetting) 
proposed in the IHA renewal are identical to those analyzed in the 
initial IHA. Similarly, the location and timing (e.g., seasonality) are 
identical to those analyzed in the initial IHA. The IHA renewal is 
valid from October 19, 2022 through September 14, 2023.

Description of Marine Mammals

    A description of the marine mammals in the area of the activities 
for which take is authorized here, including information on abundance, 
status, distribution, and hearing, may be found in the Federal Register 
notice of the proposed IHA for the 2020 IHA (85 FR 21179; April 16, 
2020). NMFS has reviewed recent draft Stock Assessment Reports, 
information on relevant Unusual Mortality Events, and other scientific 
literature, and determined that neither this nor any other new 
information 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 take is 
authorized here may be found in the Federal Register notice of the 
proposed IHA for the 2020 IHA (85 FR 21179; April 16, 2020). The Navy's 
revised construction design plan includes some pile sizes and types 
that were not included in the initial IHA (e.g., addition of 18-inch 
octagonal piles and 14-inch steel H-piles). However, the estimated 
sound source levels for the smaller (18-inch) concrete piles and the 
steel H-piles are lower than the source levels for the larger (24-inch) 
concrete piles and the 24-inch steel pipe piles, respectively, that 
were planned to be used during the activity described in the initial 
IHA (described in detail in the Navy's IHA renewal request, available 
at www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-construction-activities). Therefore, NMFS has 
determined that the effects of the Navy's planned installation of these 
new pile sizes and types on marine mammals and their habitat are the 
same as those analyzed in the initial IHA. Additionally, NMFS has 
reviewed recent draft Stock Assessment Reports, information on relevant 
Unusual Mortality Events, and other scientific literature, and 
determined that neither this nor any other new information 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 
notices for the proposed and final 2020 IHA (85 FR 21179; April 16, 
2020 and 85 FR 33129; June 1, 2020). The marine mammal occurrence data 
applicable to this authorization remain unchanged from

[[Page 64769]]

the previously issued IHA. Similarly, the stocks taken, methods of 
take, and types of take remain unchanged from the previously issued 
IHA. The take calculation method also remains the same as for the 
initial IHA, with the exception of fewer days of activity than what was 
described in the initial IHA.
    The initial IHA estimated the distances to the Level B harassment 
thresholds for each pile size and type that was planned to be included 
in the initial construction plan. In the initial IHA, the largest Level 
B harassment zone resulted from vibratory installation of 24-inch steel 
pipe piles (1,848 m). However, since 24-inch steel pipe piles are no 
longer planned to be installed, the largest Level B harassment zone now 
results from vibratory installation of 14-inch steel H-piles (398 m).
    Based on the number of piles to be installed, the Navy estimates 
that the planned pile driving activity will take 40 days (Table 1). As 
in the initial IHA, the Navy estimates four California sea lions could 
be present in the project area each day. Multiplication of the above 
estimate of animals per day (4) times the days of work (40) results in 
an authorized 160 incidents of Level B harassment take of California 
sea lions (Table 2). The Navy intends to avoid Level A harassment take 
by shutting down activities if a California sea lion approaches within 
25 m of the project site, which encompasses all estimated Level A 
harassment zones. Therefore, no take by Level A harassment is 
anticipated or authorized.

Description of Mitigation, Monitoring and Reporting Measures

    The mitigation, monitoring, and reporting measures included as 
requirements in this authorization are identical to those included in 
the Federal Register notice announcing the issuance of the 2020 IHA (85 
FR 33129; June 1, 2020), and the discussion of the least practicable 
adverse impact included in that document remains accurate. The 
following measures are included in this renewal:
Mitigation
    The Navy must conduct briefings between construction supervisors 
and crews and the marine mammal monitoring team prior to the start of 
all pile driving activity, and when new personnel join the work, to 
explain responsibilities, communication procedures, marine mammal 
monitoring protocol, and operational procedures.
    For in-water heavy machinery work other than pile driving (e.g., 
standard barges, etc.), if a marine mammal comes within 10 m, 
operations must cease and vessels must reduce speed to the minimum 
level required to maintain steerage and safe working conditions. This 
type of work could include the following activities: (1) movement of 
the barge to the pile location; or (2) positioning of the pile on the 
substrate via a crane (i.e., stabbing the pile).
    Though not required, Navy has indicated that in-water pile driving 
would only be conducted at least 30 minutes after sunrise and up to 30 
minutes before sunset, when visual monitoring of marine mammals can be 
conducted.
    For those marine mammals for which Level B harassment take has not 
been requested, in-water pile driving must shut down immediately if 
such species are observed within or entering the monitoring zone (i.e., 
Level B harassment zone). If take reaches the authorized limit for an 
authorized species, pile installation must be stopped as these species 
approach the Level B harassment zone to avoid additional take.
    Establishment of Shutdown Zone for Level A Harassment--For all pile 
driving activities, the Navy must establish a shutdown zone. The 
purpose of a shutdown zone is generally to define an area within which 
shutdown of activity would occur upon sighting of a marine mammal (or 
in anticipation of an animal entering the defined area). Conservative 
shutdown zones of 25 m for impact and vibratory pile driving activities 
must be implemented for California sea lions. The placement of 
protected species observers (PSOs) during all pile driving activities 
(described in detail in the Monitoring section below) must ensure 
shutdown zones are visible.
    Establishment of Monitoring Zones for Level B Harassment--The Navy 
must establish monitoring zones corresponding with the estimated Level 
B harassment zones. Monitoring zones provide utility for observing by 
establishing monitoring protocols for areas adjacent to the shutdown 
zones. Monitoring zones enable observers to be aware of and communicate 
the presence of marine mammals in the project area outside the shutdown 
zone and thus prepare for a potential cessation of activity should the 
animal enter the shutdown zone.

------------------------------------------------------------------------

    Soft Start--The use of soft-start procedures is believed to provide 
additional protection to marine mammals by providing warning and/or 
giving marine mammals a chance to leave the area prior to the hammer 
operating at full capacity. For impact pile driving, contractors are 
required to provide an initial set of strikes from the

[[Page 64770]]

hammer at reduced energy, with each strike followed by a 30-second 
waiting period. This procedure must be conducted a total of three times 
before impact pile driving begins. Soft start must be implemented at 
the start of each day's impact pile driving and at any time following 
cessation of impact pile driving for a period of 30 minutes or longer. 
Soft start is not required during vibratory pile driving activities.
    Pre-Activity Monitoring--Prior to the start of daily in-water 
construction activity, or whenever a break in pile driving of 30 
minutes or longer occurs, PSOs must observe the shutdown and monitoring 
zones for a period of 30 minutes. The shutdown zone is considered 
cleared when a marine mammal has not been observed within the zone for 
that 30-minute period. If a marine mammal is observed within the 
shutdown zone, a soft-start must not proceed until the animal has left 
the zone or has not been observed for 15 minutes. If the Level B 
harassment zone has been observed for 30 minutes and species with no 
take authorization are not present within the zone, soft start 
procedures can commence and work can continue even if visibility 
becomes impaired within the Level B harassment monitoring zone. When a 
marine mammal for which take by Level B harassment is authorized is 
present in the Level B harassment zone, activities may begin and Level 
B harassment take will be recorded. If work ceases for more than 30 
minutes, the pre-activity monitoring of both the Level B harassment and 
shutdown zone must commence again.
Monitoring
    Marine Mammal Visual Monitoring-- Monitoring must be conducted by 
NMFS-approved observers. Trained observers must be placed from the best 
vantage point(s) practicable to monitor for marine mammals and 
implement shutdown or delay procedures when applicable through 
communication with the equipment operator. Observer training must be 
provided prior to project start, and must include instruction on 
species identification (sufficient to distinguish the species in the 
project area), description and categorization of observed behaviors and 
interpretation of behaviors that may be construed as being reactions to 
the specified activity, proper completion of data forms, and other 
basic components of biological monitoring, including tracking of 
observed animals or groups of animals such that repeat sound exposures 
may be attributed to individuals (to the extent possible).
    Monitoring must be conducted 30 minutes before, during, and 30 
minutes after pile driving activities. In addition, observers must 
record all incidents of marine mammal occurrence, regardless of 
distance from activity, and must document any behavioral reactions in 
concert with distance from piles being driven. Pile driving activities 
include the time to install a single pile or series of piles, as long 
as the time elapsed between uses of the pile driving equipment is no 
more than 30 minutes.
    At least one land-based PSO must be located at the project site, 
and the Navy has indicated that when possible and appropriate during 
vibratory pile driving activities, one additional boat-based PSO will 
be located at the edge of the Level B harassment isopleth (see Figure 
1-2 of the Marine Mammal Monitoring Plan dated March, 2020; available 
at https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-construction-activities).
    PSOs must scan the waters using binoculars, and/or spotting scopes, 
and must use a handheld GPS or range-finder device to verify the 
distance to each sighting from the project site. All PSOs must be 
trained in marine mammal identification and behaviors and must have no 
other project-related tasks while conducting monitoring. In addition, 
monitoring must be conducted by qualified observers, who must be placed 
at the best vantage point(s) practicable to monitor for marine mammals 
and implement shutdown/delay procedures when applicable by calling for 
the shutdown to the hammer operator. The Navy must adhere to the 
following PSO qualifications:
    (i) Independent observers (i.e., not construction personnel) are 
required;
    (ii) At least one observer must have prior experience working as an 
observer;
    (iii) Other observers may substitute education (degree in 
biological science or related field) or training for experience;
    (iv) Where a team of three or more observers are required, one 
observer must be designated as lead observer or monitoring coordinator. 
The lead observer must have prior experience working as an observer; 
and
    (v) The Navy must submit observer CVs for approval by NMFS.
    Additional standard observer qualifications include:
     Ability to conduct field observations and collect data 
according to assigned protocols;
     Experience or training in the field identification of 
marine mammals, including the identification of behaviors;
     Sufficient training, orientation, or experience with the 
construction operation to provide for personal safety during 
observations;
     Writing skills sufficient to prepare a report of 
observations including, but not limited to, the number and species of 
marine mammals observed; dates and times when in-water construction 
activities were conducted; dates and times when in-water construction 
activities were suspended to avoid potential incidental injury from 
construction sound of marine mammals observed within a defined shutdown 
zone; and marine mammal behavior; and
     Ability to communicate orally, by radio or in person, with 
project personnel to provide real-time information on marine mammals 
observed in the area as necessary.
    Observers are required to use approved data forms (see data 
collection forms in the applicant's Marine Mammal Mitigation and 
Monitoring Plan). Among other pieces of information, the Navy must 
record detailed information about any implementation of shutdowns, 
including the distance of animals to the pile and description of 
specific actions that ensued and resulting behavior of the animal, if 
any. In addition, the Navy must attempt to distinguish between the 
number of individual animals taken and the number of incidences of 
take.

Reporting

    A draft report must be submitted to NMFS within 90 days of the 
completion of marine mammal monitoring, or 60 days prior to the 
requested date of issuance of any future IHA for projects at the same 
location, whichever comes first. The report must include marine mammal 
observations pre-activity, during-activity, and post-activity during 
pile driving days (and associated PSO data sheets), and must also 
provide descriptions of any behavioral responses to construction 
activities by marine mammals and a complete description of all 
mitigation shutdowns and the results of those actions and an 
extrapolated total take estimate based on the number of marine mammals 
observed during the course of construction. A final report must be 
submitted within 30 days following resolution of comments on the draft 
report. At minimum, the following information must be collected on all 
sighting forms and included in the monitoring report:
     Dates and times (begin and end) of all marine mammal 
monitoring;

[[Page 64771]]

     Construction activities occurring during each daily 
observation period, including how many and what type of piles were 
driven or removed and by what method (i.e., impact or vibratory);
     Weather parameters and water conditions during each 
monitoring period (e.g., wind speed, percent cover, visibility, sea 
state);
     The number of marine mammals observed, by species, 
relative to the pile location and if pile driving or removal was 
occurring at time of sighting;
     Age and sex class, if possible, of all marine mammals 
observed;
     PSO locations during marine mammal monitoring;
     Distances and bearings of each marine mammal observed to 
the pile being driven or removed for each sighting (if pile driving or 
removal was occurring at time of sighting);
     Description of any marine mammal behavior patterns during 
observation, including direction of travel and estimated time spent 
within the Level A and Level B harassment zones while the source was 
active;
     Number of individuals of each species (differentiated by 
month as appropriate) detected within the monitoring zone, and 
estimates of number of marine mammals taken, by species (a correction 
factor may be applied to total take numbers, as appropriate);
     Detailed information about any implementation of any 
mitigation triggered (e.g., shutdowns and delays), a description of 
specific actions that ensued, and resulting behavior of the animal, if 
any;
     Description of attempts to distinguish between the number 
of individual animals taken and the number of incidences of take, such 
as ability to track groups or individuals;
     An extrapolation of the estimated takes by Level B 
harassment based on the number of observed exposures within the Level B 
harassment zone and the percentage of the Level B harassment zone that 
was not visible; and
     Submit all PSO datasheets and/or raw sighting data (in a 
separate file from the final report referenced immediately above).
    In the event that personnel involved in the construction activities 
discover an injured or dead marine mammal, the Navy must report the 
incident to the Office of Protected Resources (OPR) (301-427-8401), 
NMFS and to the West Coast Region Stranding Coordinator (562-980-3230) 
as soon as feasible. If the death or injury was clearly caused by the 
specified activity, the Navy must immediately cease the specified 
activities until NMFS is able to review the circumstances of the 
incident and determine what, if any, additional measures are 
appropriate to ensure compliance with the terms of the IHA. The Navy 
must not resume their activities until notified by NMFS. The report 
must include the following information:
     Time, date, and location (latitude/longitude) of the first 
discovery (and updated location information if known and applicable);
     Species identification (if known) or description of the 
animal(s) involved;
     Condition of the animal(s) (including carcass condition if 
the animal is dead);
     Observed behaviors of the animal(s), if alive;
     If available, photographs or video footage of the 
animal(s); and
     General circumstances under which the animal was 
discovered.
    NMFS will work with the Navy to determine what, if anything, is 
necessary to minimize the likelihood of further prohibited take and 
ensure MMPA compliance. The Navy must not resume their activities until 
notified by NMFS.

Comments and Responses

    A notice of NMFS' proposal to issue a renewal IHA to the Navy was 
published in the Federal Register on September 20, 2022 (87 FR 57473). 
That notice either described, or referenced descriptions of, the Navy's 
activity, the marine mammal species that may be affected by the 
activity, the anticipated effects on marine mammals and their habitat, 
estimated amount and manner of take, and proposed mitigation, 
monitoring and reporting measures. During the 30-day public comment 
period, NMFS received no public comments.

Determinations

    The construction activities planned by the Navy are nearly 
identical to those analyzed in the initial IHA. Due to the construction 
design-plan changes, the planned number of days of activity are fewer 
than the initial IHA. The method of taking and effects of the action 
are identical to those analyzed in the initial IHA. The potential 
effects of the Navy's activities are limited to Level B harassment in 
the form of behavioral disturbance and temporary threshold shift. In 
analyzing the effects of the activities in the initial IHA, NMFS 
determined that the Navy's activities would have a negligible impact on 
the affected species or stocks and that the authorized take numbers of 
each species or stock were small relative to the relevant stocks (e.g., 
less than one-third of the abundance of all stocks). The mitigation 
measures and monitoring and reporting requirements as described above 
are identical to the initial IHA.
    NMFS has concluded that there is no new information suggesting that 
our analysis or findings should change from those reached for the 
initial IHA. 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) the Navy'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.

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 action (i.e., the issuance of an IHA renewal) 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 determined 
that the issuance of the IHA renewal qualifies to be categorically 
excluded from further NEPA review.

Endangered Species Act

    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. No incidental take of ESA-listed marine mammal 
species is expected to result

[[Page 64772]]

from this activity, and none would be authorized. Therefore, NMFS has 
determined that consultation under section 7 of the ESA is not required 
for this action.

Renewal

    NMFS has issued a renewal IHA to the Navy for the take of marine 
mammals incidental to conducting the Floating Dry Dock Project at Naval 
Base San Diego in San Diego, California, effective October 19, 2022 
through September 14, 2023.
