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 promulgated or, if the taking is limited to harassment, an IHA 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''). NMFS must also prescribe requirements pertaining to
monitoring and reporting of such takings. The definition of key terms
such as ``take,'' ``harassment,'' and ``negligible impact'' can be
found in the MMPA and NMFS's implementing regulations (see 16 U.S.C.
1362; 50 CFR 216.103).
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 IHA, NMFS described the circumstances under which we
would consider issuing a renewal for this activity, and requested
public comment on a potential renewal under those circumstances.
Specifically, on a case-by-case basis, NMFS may issue a one-time 1-year
renewal 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 July 31, 2023, NMFS issued an IHA to Caltrans to take marine
mammals incidental to Phase II of the Richmond-San Rafael Bridge
Restoration Project in Richmond, California (88 FR 51778, August 4,
2023), effective from August 1, 2023 through March 30, 2024. On
February 7, 2023, NMFS received an application for the renewal of that
initial 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 a
preliminary monitoring report (available at <a href="https://www.fisheries.noaa.gov/action/incidental-take-authorization-california-department-transportations-richmond-san-rafael">https://www.fisheries.noaa.gov/action/incidental-take-authorization-california-department-transportations-richmond-san-rafael</a>) which confirms
[[Page 22129]]
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 March 4, 2024 (89 FR 15549).
Description of the Specified Activities and Anticipated Impacts
Under the initial IHA Caltrans proposed to conduct construction
activities to restore a portion of the Richmond-San Rafael Bridge.
Prior to restoration work Caltrans would install a debris containment
system to ensure contaminants from construction are not deposited into
San Francisco Bay. Caltrans and NMFS concluded that during the
deployment and retrieval of the containment system disturbance (i.e.,
Level B harassment) may occur to harbor seals hauled out at Castro
Rocks. Castro Rocks is an important haulout location for harbor seals
that is close to the portion of the Richmond-San Rafael Bridge where
construction work is occurring.
Under the initial IHA Caltrans took 19 days to deploy the debris
containment system and during this time protected species observers
(PSOs) did not observe any disturbance of harbor seals hauled out at
Castro Rocks. Caltrans will be unable to remove the debris containment
system before the expiration of the initial IHA. Therefore, this
renewal will allow for the removal of the debris containment system and
completion of the restoration project. NMFS authorized 9,000 takes of
harbor seals by Level B harassment under the initial IHA, for the
installation and removal of the debris containment system. This renewal
will authorize a portion of the number of takes authorized in the
initial IHA based on the days remaining to complete the work.
All documents related to the initial IHA and the applicant's
request for renewal are available on our website at: <a href="https://www.fisheries.noaa.gov/action/incidental-take-authorization-california-department-transportations-richmond-san-rafael">https://www.fisheries.noaa.gov/action/incidental-take-authorization-california-department-transportations-richmond-san-rafael</a>.
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 (88
FR 41920, June 28, 2023) and Final IHAs (88 FR 51778, August 4, 2023)
for the initial authorization. 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 from April 1, 2024 through March 30, 2025.
Description of Marine Mammals
A description of the marine mammals in the area of the activities
for which authorization of take is proposed here, including information
on abundance, status, distribution, and hearing, may be found in the
Federal Register notice of the Proposed IHA (88 FR 41920, June 28,
2023) for the initial authorization. NMFS has reviewed the monitoring
data from the initial IHA, 2023 draft Stock Assessment Reports,
information on relevant Unusual Mortality Events, and other scientific
literature, and determined there is no new information that affects
which species or stocks have the potential to be affected or the
pertinent information in the Description of the Marine Mammals in the
Area of Specified Activities contained in the supporting documents for
the initial IHA.
Potential Effects on Marine Mammals and Their Habitat
A description of the potential effects of the specified activity on
marine mammals and their habitat may be found in the Federal Register
notice of the Proposed IHA (88 FR 41920, June 28, 2023) for the initial
authorization. NMFS has reviewed the monitoring data from the initial
IHA, recent draft Stock Assessment Reports, information on relevant
Unusual Mortality Events, and other scientific literature, and
determined that there is no new information that affects our initial
analysis of impacts on marine mammals and their habitat.
Estimated Take
The initial IHA assumed a daily occurrence rate of 300 harbor seals
per day on Castro Rocks. Caltrans expected the installation and removal
of the debris containment system to take approximately 30 days.
Therefore, the initial IHA authorized a total of 9,000 takes by Level B
harassment to complete the installation and removal of the debris
containment system. Under the initial IHA Caltrans installed the debris
containment system over a 19 day period and no takes by Level B
harassment of harbor seals were observed during that time. The removal
of the debris containment system will not be completed before the
initial IHA expires.
This IHA renewal will authorize take by Level B harassment of
harbor seals during the removal of the debris containment system. It is
expected to take a total of 10 days to remove the debris containment
system once the construction activities are completed. NMFS assumes a
similar daily occurrence rate of 300 harbor seals per day on Castro
Rocks which over the 10 days of remaining work will equate to a total
of 3,000 takes by Level B harassment of harbor seals under this renewal
IHA. A detailed description of the methods and inputs used to estimate
take for the specified activity are found in the Federal Register
notices of the Proposed IHA (88 FR 41920, June 28, 2023) and Final IHA
(88 FR 51778, August 4, 2023) for the initial authorization.
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
the Federal Register notice of the Proposed IHA (88 FR 41920, June 28,
2023) remains accurate. The following mitigation measures are required
for this renewal:
<bullet> Seasonal Work Restrictions: installation or removal of the
debris containment system must not occur between Piers 52-57 from April
1-July 31 due to the pupping and molting period of harbor seals;
<bullet> Work must not take place outside of the containment system
on the bridge between Piers 52-57 from April 1 to July 31;
<bullet> A non-disturbance buffer will be established within 400
feet (121 meters) of Castro Rocks on the south side of bridge;
<bullet> Staging of barges will not be allowed in the project area;
<bullet> Routes for watercraft to reach work locations will be
predetermined in consultation with the project biologist to avoid
harassment or take of marine mammals hauled out at Castro Rocks; and
<bullet> No piles may be driven or vibrated to create staging
locations for any watercraft. Barges and vessels will be tethered to
the existing concrete bridge piers.
The following monitoring and reporting measures are required for
this renewal:
<bullet> Caltrans will monitor to collect data on marine mammal
behavior, counts of the individuals observed, and the frequency of the
observations. Caltrans will collect sighting data and observations on
behavioral responses to construction for marine mammal
[[Page 22130]]
species observed in the region of activity during the period of
construction. All observers will be trained in the identification of
marine mammals and marine mammal behaviors;
<bullet> PSOs must be independent observers (i.e., not construction
personnel). All PSOs must have the ability to conduct field
observations and collect data according to assigned protocols, be
experienced in field identification of marine mammals and their
behaviors. Caltrans must submit their resumes to NMFS for approval;
<bullet> Biological monitoring must occur 5 days prior to the
Project's start date, to establish baseline observations;
<bullet> Observation periods will encompass different tide levels
and hours of the day. Monitoring of marine mammals around the
construction site will be conducted using binoculars as necessary; and
<bullet> The location of the PSOs will be at a monitoring platform
positioned on Pier 55 of the Richmond-San Rafael Bridge, at the closest
pier of the Richmond-San Rafael Bridge to Castro Rocks. Pier 55 is
approximately 21 meters from the nearest rock at Castro Rocks harbor
seal colony.
Caltrans shall submit a draft report to NMFS within 90 days of the
completion of marine mammal monitoring, or 60 days prior to the
issuance of any subsequent IHA for this project (if required),
whichever comes first. The annual report will detail the monitoring
protocol, summarize the data recorded during monitoring, and estimate
the number of marine mammals that may have been harassed. If no
comments are received from NMFS within 30 days, the draft final report
will become final. If comments are received, a final report must be
submitted up to 30 days after receipt of comments. All PSO datasheets
and/or raw sighting data must be submitted with the draft marine mammal
report.
Reports shall contain the following information:
<bullet> Dates and times (begin and end) of all marine mammal
monitoring;
<bullet> Construction activities occurring during each daily
observation period including: (a) what type of restoration work is
being completed, and (b) the total duration of work completed;
<bullet> PSO locations during monitoring; and
<bullet> Environmental conditions during monitoring periods (at
beginning and end of PSO shift and whenever conditions change
significantly), including sea state and any other relevant weather
conditions including cloud cover, fog, sun glare, and overall
visibility to the horizon, and estimated observable distance.
Upon observation of a marine mammal, the following information must
be reported:
<bullet> Name of PSO who sighted the animal(s) and PSO location and
activity at time of sighting;
<bullet> Time of sighting;
<bullet> Identification of the animal(s) (e.g., genus/species,
lowest possible taxonomic level, or unidentified), and PSO confidence
in identification;
<bullet> Distance and location of each observed marine mammal
relative to the bridge restoration work;
<bullet> Estimated number of animals by species (min/max/best
estimate);
<bullet> Estimated number of animals by cohort (adults, pups, and
group composition, etc.);
<bullet> Description of any marine mammal behavioral observations
(e.g., observed behaviors such as feeding or traveling), including an
assessment of behavioral responses thought to have resulted from the
activity (e.g., no response or changes in behavioral state such
flushing or head posturing); and
<bullet> Detailed information about implementation of any
mitigation measures, a description of specified actions that ensured,
and resulting changes in behavior of the animal(s), if any.
Comments and Responses
A notice of NMFS' proposal to issue a renewal IHA to Caltrans was
published in the Federal Register on March 3, 2024 (89 FR 15549). That
notice either described, or referenced descriptions of, the Caltrans'
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 on
the proposed IHA renewal notice.
Determinations
The activities conducted under this potential renewal will be a
subset of the activities authorized under the initial IHA.
Specifically, this renewal will authorize take incidental to the
removal of the debris containment system. Removal of the debris
containment system is expected to take 10 days. Take incidental to this
activity was originally authorized under the initial IHA but Caltrans
could not complete the removal of the debris containment system before
the initial IHA expired. In analyzing the effects of the activities for
the initial IHA, NMFS determined that the Caltrans' activities will
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). There is no new information that affects NMFS' determinations
supporting issuance initial IHA or this renewal. 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) Caltrans' 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
This action is consistent with categories of activities identified
in Categorical Exclusion B4 (incidental take authorizations with no
anticipated serious injury or mortality) of the Companion Manual for
NOAA Administrative Order 216-6A, which do not individually or
cumulatively have the potential for significant impacts on the quality
of the human environment and for which we have not identified any
extraordinary circumstances that would preclude this categorical
exclusion. Accordingly, NMFS determined that the issuance of the
initial IHA qualified to be categorically excluded from further
National Environmental Policy Act review. NMFS has determined that the
application of this categorical exclusion remains appropriate for this
renewal IHA.
Endangered Species Act
No incidental take of Endangered Species Act (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 Caltrans for the take of marine
mammals incidental to conducting Phase II of the Richmond-San Rafael
Bridge Restoration Project in Richmond, California valid from April 1,
2024 through March 30, 2025.
