SUPPLEMENTARY INFORMATION:
Background
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, 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). 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 1 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
[[Page 62346]]
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 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:
<bullet> 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).
<bullet> 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: <a href="https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals">https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals</a>.
History of Request
On September 16, 2021, NMFS issued an IHA to CDFW to take marine
mammals incidental to Phase III of the Elkhorn Slough Tidal Marsh
Restoration Project in Monterey County, CA (86 FR 52644, September 22,
2021), effective from September 16, 2021 through September 15, 2022. On
July 12, 2022, CDFW informed NMFS that the project was delayed and none
of the work identified in the initial IHA (i.e., restoration work at
the Seal Bend Restoration Area) had occurred, and submitted a request
for re-issuance of the initial IHA with new effective dates of
September 16, 2022, through September 15, 2023 (87 FR 56631, September
15, 2022). On July 6, 2023, NMFS received an application for the
renewal of the IHA. As described in the application for renewal, the
activities for which incidental take is requested consist of activities
that are covered by the initial authorization but will not be completed
prior to its expiration. As required, the applicant also provided
preliminary monitoring results 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. The
notice of the proposed Renewal IHA was published on August 1, 2023 (88
FR 50113).
Description of the Specified Activities and Anticipated Impacts
Phase III of CDFW's construction Elkhorn Slough Tidal Marsh
Restoration Project consists of relocating soil from an upland area
through the use of heavy earth-moving equipment to the Seal Bend
Restoration Area, and will restore 28.6 acres (11.57 hectares) within a
12 month period. The planned activities (including mitigation,
monitoring, and reporting) and anticipated impacts on the affected
stocks are the same as those analyzed and authorized through the
initial IHA.
A detailed description of the planned restoration activities is
found in the Federal Register notice for the proposed initial IHA (86
FR 43204, August 6, 2021). The location, timing, and nature of the
activities, including the types of equipment planned for use, are
identical to those described in the initial IHA. The mitigation and
monitoring are also as prescribed in the initial IHA.
Construction activities are expected to produce airborne noise and
visual disturbance that have the potential to result in behavioral
harassment of Pacific harbor seals (Phoca vitulina richardii). A
description of the methods and inputs used to estimate take anticipated
to occur and, ultimately, the take that was authorized is included in
the previous documents referenced above. The data inputs and methods of
estimating take are identical to those used in the initial IHA. NMFS
has reviewed recent stock assessment reports, information on relevant
unusual mortality events, and recent scientific literature, and
determined that no new information affects our original analysis of
impacts under the initial IHA. No work was completed under the initial
IHA and only 15 days of work have been completed since reissuance of
the initial IHA.
This renewal is to cover a subset of the activities described for
the initial IHA that will not be completed during the effective IHA
period. CDFW plans to continue construction activities between
September 2023 and September 2024. CDFW estimates it will take 225 days
to complete construction necessary to support restoration of the Seal
Bend Restoration Area, as only 15 days of work out of the 240 days of
planned construction are expected to be completed within the effective
dates of the currently active IHA.
The likely or possible impacts of CDFW's activity on marine mammals
could involve both non-acoustic and acoustic stressors and is unchanged
from the impacts described in the initial IHA. Potential non-acoustic
stressors could result from the physical presence of construction
equipment and personnel. Acoustic stressors include effects of heavy
equipment operation during soil excavation, transport, and placement.
The effects of airborne noise and visual disturbance from CDFW's
activities have the potential to result in Level B harassment of marine
mammals in the action area.
Detailed Description of the Activity
A detailed description of the construction activities for which
take is authorized here may be found in the notices of the proposed and
final IHAs for the initial authorization (86 FR 43204, August 6, 2021;
86 FR 52644, September 22, 2021). The location, timing, and nature of
the activities, including the types of equipment planned for use, are
identical to those described in the previous notices.
This Renewal IHA is effective for a period of 1 year from September
16, 2023 through September 15, 2024.
[[Page 62347]]
Description of Marine Mammals
A description of the marine mammals in the area of the activities
for which take is authorized, including information on abundance,
status, distribution, and hearing, may be found in the notice of the
proposed IHA for the initial authorization (86 FR 43204, August 6,
2021). NMFS has reviewed the preliminary monitoring data from the
reissued IHA, 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 (86 FR 43204, August 6, 2021).
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 notices of the
proposed IHA for the initial authorization (86 FR 43204, August 6,
2023). NMFS has reviewed the preliminary monitoring data from the
reissued IHA, recent draft stock assessment reports, information on
relevant unusual mortality events, other scientific literature, and the
public comments, 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 notice of the proposed
IHA for the initial authorization (86 FR 43204, August 6, 2021).
Specifically, days of operation, area or space within which harassment
is likely to occur, and marine mammal occurrence data applicable to
this authorization remain unchanged from the initial IHA. Similarly,
the stock taken, methods of take, daily take estimates, and types of
take remain unchanged from the initial IHA. The number of takes
authorized through the renewal IHA are a subset of the initially
authorized takes that represent the amount of activity left to
complete. These takes, which reflect the lower number of remaining days
of work (225 days), are indicated below in Table 1.

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 initial IHA,
and the discussion of the least practicable adverse impact included in
that document and the notice of the proposed IHA remains accurate. The
following measures are included in the renewal IHA:
<bullet> Construction work must occur only during daylight hours
and should environmental conditions deteriorate such that marine
mammals within the entire shutdown zone would not be visible (e.g.,
fog, heavy rain, smoke), construction must be delayed until the
Protected Species Observer (PSO) is confident marine mammals within the
shutdown zone could be detected;
<bullet> CDFW must fulfill visual monitoring requirements, which
includes the use of NMFS-approved PSOs and the establishment of a Level
B harassment zone within 300 meters (m) of all construction activities;
<bullet> A 30 minute pre-construction clearance period must occur
prior to the start of ramp-up (e.g., ramp up by moving around the
project area and starting equipment sequentially) and construction
activities;
<bullet> CDFW must shutdown heavy machinery work if a marine mammal
comes within 10 m;
<bullet> During harbor seal pupping season (March through July),
CDFW must not initiate construction activities within 300 m of a mom/
pup pair that is hauled out, or within 100 m of a mom/pup pair in the
water. If there is a gap in construction activities of more than an
hour or if construction moves to a different area, this initiation
protocol must again be implemented. During site containment activities
that are underway, heavy machinery must not approach closer than 100 m
of where mothers and pups are actively hauled out. If a pup less than 1
week old (neonate) comes within 20 m of where heavy machinery is
working, construction activities in that area must be shut down or
delayed until the pup has left the area. In the event that a pup less
than 1 week old remains within those 20 m, NMFS will be consulted to
determine the appropriate course of action;
<bullet> Construction activities must be halted upon observation of
either a species for which incidental take is not authorized or a
species for which incidental take has been authorized but the
authorized number of takes has been met, entering or within the
harassment zone;
<bullet> CDFW must conduct a census of marine mammals in the
project area and the area surrounding the project at least 30 minutes
prior to the beginning of construction on monitoring days, and again 30
minutes after the completion of construction activities. CDFW must also
conduct hourly counts of animals hauled out and in the water within at
least the Level B harassment zone, as well as reactions observed in
relation to construction activities;
<bullet> CDFW must submit a draft report detailing all monitoring
within 90 calendar days of the completion of marine mammal monitoring
or 60 days prior to the issuance of any subsequent IHA for this
project, whichever comes first;
<bullet> CDFW must prepare and submit final report within 30 days
following resolution of comments on the draft report from NMFS;
<bullet> CDFW must submit all PSO datasheets and/or raw sighting
data (in a separate file (e.g., Microsoft Excel or similar) from the
Final Report referenced immediately above); and,
<bullet> CDFW must report injured or dead marine mammals.
Comments and Responses
A notice of NMFS' proposal to issue a Renewal IHA to CDFW was
published in the Federal Register on August 1, 2023 (88 FR 50113). That
notice either
[[Page 62348]]
described, or referenced descriptions of, CDFW'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. NMFS received no public comments.
Determinations
The renewal request consists of a subset of activities analyzed
through the initial authorization described above. In analyzing the
effects of the activities for the initial IHA, NMFS determined that the
CDFW's activities would have a negligible impact on the affected
species or stock and that authorized take numbers of each species or
stock were small relative to the relevant stocks (e.g., less than one-
third 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) CDFW'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 proposed 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 (incidental take authorizations with no
anticipated serious injury or mortality) of the Companion Manual for
NAO 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 determined that the application of this categorical exclusion
remains appropriate for this Renewal IHA.
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. To ensure ESA compliance for the issuance of IHAs,
NMFS consults internally whenever we propose to authorize take for
endangered or threatened species.
No incidental take of ESA-listed species is authorized or expected
to result from this activity. Therefore, NMFS has determined that
formal consultation under section 7 of the ESA is not required for this
action.
Renewal
NMFS has issued a Renewal IHA to CDFW for the take of marine
mammals incidental to conducting construction activities associated
with Phase III of the Elkhorn Slough Tidal Marsh Restoration Project in
Monterey County, CA, from September 16, 2023, through September 15,
2024.
