Abstract
NMFS received a request from Municipality of Skagway (MOS) for the renewal of their currently active incidental harassment authorization (IHA) to take marine mammals incidental to the terminal redevelopment project in Skagway, Alaska. MOS's activities consist of activities that are covered by the current authorization but will not be completed prior to its expiration. Pursuant to the Marine Mammal Protection Act (MMPA), prior to issuing the currently active IHA, NMFS requested comments on both the proposed IHA and the potential for renewing the initial authorization if certain requirements were satisfied. The renewal requirements have been satisfied, and NMFS is now providing an additional 15-day comment period to allow for any additional comments on the proposed renewal not previously provided during the initial 30-day comment period.

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
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''). 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 the 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 of an IHA following notice to the public providing an
additional 15 days for public comments when: (1) up to another year of
identical, or nearly identical, activities as described in the Detailed
Description of Specified Activities section of the initial IHA issuance
notice is planned; or (2) the activities as described in the
Description of the Specified Activities and Anticipated Impacts section
of the initial IHA issuance notice would not be completed by the time
the initial IHA expires and a renewal would allow for completion of the
activities beyond that described in the DATES section of the notice of
issuance of the initial IHA, provided all of the following conditions
are met:
1. A request for renewal is received no later than 60 days prior to
the needed renewal IHA effective date (recognizing that the renewal IHA
expiration date cannot extend beyond 1 year from expiration of the
initial IHA);
2. The request for renewal must include the following:
<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
[[Page 84334]]
the exception of reducing the type or amount of take); and
<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; and
3. Upon review of the request for renewal, the status of the
affected species or stocks, and any other pertinent information, NMFS
determines that there are no more than minor changes in the activities,
the mitigation and monitoring measures will remain the same and
appropriate, and the findings in the initial IHA remain valid.
An additional public comment period of 15 days (for a total of 45
days), with direct notice by email, phone, or postal service to
commenters on the initial IHA, is provided to allow for any additional
comments on the proposed renewal. A description of the renewal process
may be found on our website at: <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>. Any comments received on the potential renewal, along with
relevant comments on the initial IHA, have been considered in the
development of this proposed IHA renewal, and a summary of agency
responses to applicable comments is included in this notice. NMFS will
consider any additional public comments prior to making any final
decision on the issuance of the requested renewal, and agency responses
will be summarized in the final notice of our decision.
National Environmental Policy Act
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
NOAA Administrative Order 216-6A, which do not individually or
cumulatively have the potential for significant impacts on the quality
of the human environment and for which we have not identified any
extraordinary circumstances that would preclude this categorical
exclusion. Accordingly, NMFS determined that the issuance of the
initial IHA qualified to be categorically excluded from further NEPA
review. NMFS has preliminarily determined that the application of this
categorical exclusion remains appropriate for this renewal IHA.
History of Request
On August 29, 2023, NMFS issued an IHA to MOS to take marine
mammals incidental to the terminal redevelopment project in Skagway,
Alaska (88 FR 60652, September 5, 2023), effective from October 1,
2023, through September 30, 2024. On February 5, 2024, NMFS received a
request from MOS to modify the 2023 IHA; adding 2 takes by Level A
harassment and 45 takes by Level B harassment for northern fur seal,
and to adjust take requests based on average species densities
throughout the year due to work occurring in all seasons and,
consequently, increasing authorized take by Level B harassment to 270
for Steller sea lion. On May 3, 2024, NMFS issued Skagway a
modification of the initial 2023 IHA (89 FR 36765).
On July 22, 2024, NMFS received an application for the renewal of
the initial IHA (as modified). After discussions with MOS about the
proposed work to be conducted under the renewal IHA, we received a
revised renewal request on September 30, 2024. As described in the
application for renewal IHA, the activities for which incidental take
is requested consist of a subset of the activities that were covered by
the initial authorization but which were not completed prior to its
expiration. As required, the applicant also provided a final monitoring
report, available online at: <a href="https://www.fisheries.noaa.gov/action/incidental-take-authorization-municipality-skagways-skagway-ore-terminal-redevelopment">https://www.fisheries.noaa.gov/action/incidental-take-authorization-municipality-skagways-skagway-ore-terminal-redevelopment</a>. The report 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.
Description of the Specified Activities and Anticipated Impacts
MOS planned to redevelop the Skagway Ore Terminal in Skagway,
Alaska, with 196 days of pile installation and removal. This project
involved installation and removal of 36 temporary steel pile guides,
removal of 692 piles, and installation of 244 permanent steel piles.
Two different installation methods were used: vibratory pile driving
and impact pile driving. Due to unexpected delays, MOS did not complete
the construction during the initial 1-year period, completing removal
of 385 piles and installation of 101 piles.
This renewal request is to cover a subset of the activities covered
in the initial IHA that was not completed during the effective IHA
period and which is planned to occur during the effective period of the
proposed renewal IHA. Specifically, MOS plans to install two 24-in
piles and remove ten timber piles, which are necessary to stabilize a
single existing fender. The remainder of the initially planned work
would not be conducted under this proposed renewal IHA.
The likely or possible impacts of the MOS's proposed activity on
marine mammals is unchanged from the impacts described in the initial
IHA. Potential non-acoustic stressors could result from the physical
presence of the equipment, vessels, and personnel; however, any impacts
to marine mammals are expected to primarily be acoustic in nature.
Sounds resulting from pile installation, removal, and drilling may
result in the incidental take of marine mammals by Level A and Level B
harassment in the form of auditory injury or behavioral harassment.
Detailed Description of the Activity
A detailed description of the construction activities for which
take is proposed here may be found in the notices of the proposed and
final IHAs for the initial authorization (88 FR 23627, April 18, 2023;
88 FR 60652, September 5, 2023). As previously mentioned, this request
is for a subset of the activities considered for the initial IHA that
were not completed prior to its expiration and which are planned to
occur under this proposed renewal IHA. The location, timing, and nature
of the activities, including the types of equipment planned for use,
are identical to those described in the previous notice for the initial
IHA. The proposed renewal IHA would be effective from the date of
issuance through September 30, 2025.
The subset of activities to be completed under this proposed
renewal IHA includes installation of two 24-in steel piles by vibratory
and impact pile driving and vibratory removal of ten timber piles. MOS
proposes that this subset of activities would take approximately 4
days, including 2 days for the pile installation and 2 days for the
pile removal.
Description of Marine Mammals
A description of the marine mammals in the area of the activities
for which
[[Page 84335]]
authorization of take is proposed here, including information on
abundance, status, distribution, and hearing, may be found in the
notice of the proposed IHA for the initial authorization and the notice
of issuance of a modified incidental harassment authorization (88 FR
23627, April 18, 2023; 89 FR 36765, May 3, 2024).
NMFS has reviewed the preliminary monitoring data from the initial
IHA, recent draft Stock Assessment Reports, and determined that neither
this nor any other new information affects which species 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 and modified
IHA (88 FR 23627, April 18, 2023; 89 FR 36765, May 3, 2024).
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 limited subset of activities
for which the authorization of take is proposed here may be found in
the notice of the proposed IHA for the initial authorization (88 FR
23627, April 18, 2023). 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 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 notices of the
proposed and final IHAs for the initial authorization and the notice of
issuance of the modified IHA (88 FR 23627, April 18, 2023; 88 FR 60652,
September 5, 2023; 89 FR 36765, May 3, 2024). Specifically, the action
area and marine mammal density and occurrence data applicable to this
authorization remain unchanged from the initial and modified IHA.
Similarly, source levels, type of activity, methods of take, and types
of take remain unchanged from the initial and modified IHA. However,
there are changes to the estimated Level A harassment zones based on
the revised amount of piles driven per day and the 2024 draft Technical
Guidance, further discussed below. The estimated number of takes
proposed for authorization is based on the subset of activities to be
completed under this renewal IHA, and therefore represents a proportion
of the initial authorized takes. These takes reflect the estimated
remaining number of days of work and number of piles to be driven.
Estimated take by Level A and Level B harassment was calculated using
the same methodology as in the initial and modified IHA.
On May 3, 2024, NMFS published (89 FR 36762) and solicited public
comment on its draft Updated Technical Guidance, which includes updated
thresholds and weighting functions to inform auditory injury estimates,
and is intended to replace the 2018 Technical Guidance referenced
above, once finalized. The public comment period ended on June 17,
2024, and although the Updated Technical Guidance is not final, we
expect the Updated Technical Guidance to represent the best available
science once it is. To best ensure we have considered an appropriate
evaluation of potential effects, in consideration of the best available
science, we have conducted basic comparative calculations using the
draft Updated Technical Guidance for the purposes of understanding the
number of takes by Level A harassment (auditory injury) that would be
predicted if the draft Updated Technical Guidance were finalized with
no changes. The relevant draft updated thresholds and weighting
functions may be found in the executive summary of the draft Updated
Technical Guidance, on pages 3 and 4. We have also considered whether
modifications to mitigation zones would be appropriate in light of the
draft Updated Technical Guidance. Based on the outcome of these
comparisons/analyses using the draft Updated Technical Guidance and the
number of piles and days of work to be conducted in this renewal, the
modeled estimates of take by Level A harassment did not present
substantial differences for any species.
In this proposed renewal, use of the draft Updated Technical
Guidance results in changes to the estimated Level A harassment zones,
but there are no changes to the estimated Level B harassment zones
(table 1). The updated Level A harassment zones are used to revise
estimations of potential take by Level A harassment. In table 2, we
have presented values based on the methodology that was included in the
previous authorizations, incorporating the previously described changes
(number of piles per day and the Updated Technical Guidance). Takes are
a proportion of the initial authorized takes and based on the days of
work included in this renewal IHA. Proposed mitigation zones, in
consideration of the updated isopleths, are discussed in the Proposed
Mitigation section.

observed only two killer whales during the initial IHA, it is possible that a larger group could enter the area during the renewal activities.
Description of Proposed Mitigation, Monitoring and Reporting Measures
The proposed mitigation, monitoring, and reporting measures
included as requirements in this authorization are substantially
similar to those included in the FR notice announcing the issuance of
the initial IHA, and the discussion of the least practicable adverse
impact included in that document remains accurate (88 FR 60652,
September 5, 2023). The only changes from the initial IHA are to the
required shutdown zones (table 3), due to the changes in Level A
harassment zone distances (table 1). As the initial IHA required
shutdown zones equal to the Level A harassment zones, we retain that
approach to mitigation in reflection of the new zones updated on the
basis of the best scientific information available. Additionally,
acoustic monitoring (as was required through the initial IHA) is not
proposed here, due to the minimal pile driving planned under this
proposed renewal IHA.

The following mitigation, monitoring, and reporting measures are
proposed for this renewal:
<bullet> The MOS must avoid direct physical interaction with marine
mammals during construction activity. If a marine mammal comes within
10-m of such activity, operations must cease and vessels must reduce
speed to the minimum level required to maintain steerage and safe
working conditions, as necessary to avoid direct physical interaction;
<bullet> Conduct training between construction supervisors and
crews and the marine mammal monitoring team and relevant MOS staff
prior to the start of all pile driving activity and when new personnel
join the work, so that responsibilities, communication procedures,
monitoring protocols, and operational procedures are clearly
understood;
<bullet> Pile driving activity 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> MOS will establish and implement the shutdown zones. The
purpose of a shutdown zone is generally to define an area within which
shutdown of the activity would occur upon sighting of a marine mammal
(or in anticipation of an animal entering the defined area). Shutdown
zones typically vary based on the activity type and marine mammal
hearing group;
<bullet> Monitoring must take place from 30 minutes prior to
initiation of construction activity (i.e., pre-start clearance
monitoring) through 30 minutes post-completion of construction
activity;
<bullet> Pre-start clearance monitoring must be conducted during
periods of visibility sufficient for the lead Protected Species
Observer (PSO) to determine the shutdown zones clear of marine mammals.
Construction may commence when the determination is made;
<bullet> If construction is delayed or halted due to the presence
of a marine mammal, the activity may not commence or resume until
either the animal has voluntarily exited and been visually confirmed
beyond the shutdown zone or 15 minutes have passed without re-detection
of the animal;
<bullet> MOS must use soft start techniques when impact pile
driving. Soft start requires contractors and equipment to slowly
approach the work site creating a visual disturbance allowing animals
in close proximity to construction activities a chance to leave the
area prior to stone resetting or new stone placement. A soft start must
be implemented at the start of each day's construction activity and at
any time following cessation of activity for a period of 30 minutes or
longer;
<bullet> The MOS must employ up to four PSOs to monitor the
shutdown and Level B harassment zones during pile driving activities;
<bullet> Monitoring will be conducted 30 minutes before, during,
and 30 minutes after construction activities. In addition, observers
shall record all incidents of marine mammal occurrence, regardless of
distance from activity, and shall document any behavioral reactions in
concert with distance from construction activity;
[[Page 84337]]
<bullet> The MOS 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> The MOS must prepare and submit final report within 30
days following resolution of comments on the draft report from NMFS;
<bullet> The MOS must submit all PSO datasheets and/or raw sighting
data (in a separate file from the Final Report referenced immediately
above); and
<bullet> The MOS must report injured or dead marine mammals.
Comments and Responses
As noted previously, NMFS published a notice of a proposed IHA and
proposed modified IHA (88 FR 23627, April 18, 2023; 89 FR 22684, April
2, 2024) and solicited public comments on both our proposal to issue
the initial IHA for Skagway Ore Terminal Redevelopment project and on
the potential for a renewal IHA, should certain requirements be met.
During the 30-day public comment period, NMFS received no substantive
comments on either the proposal to issue the initial IHA for MOS's
construction activities or on the potential for a renewal IHA.
Preliminary Determinations
The proposed 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 MOS's activities would have a negligible impact on the
affected species or stocks 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
substantially similar to those required through initial IHA;
hydroacoustic monitoring is excluded because it was completed under the
initial IHA, and the shutdown zones have been revised to reflect the
piles to be driven in the proposed subset of work.the minor changes
described above do not affect the least practicable adverse impact
determinations.
NMFS has preliminarily concluded that there is no new information
suggesting that our analysis or findings should change from those
reached for the initial IHA. Based on the information and analysis
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 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) MOS'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
The NMFS Alaska Regional Office issued a Biological Opinion under
section 7 of the Endangered Species Act (ESA; 16 U.S.C. 1531 et seq.)
on the issuance of an IHA and potential renewal IHA to MOS under
section 101(a)(5)(D) of the MMPA by the NMFS OPR. The Biological
Opinion concluded that the action is not likely to jeopardize the
continued existence of ESA-listed humpback whales or Steller sea lions.
Proposed Renewal IHA and Request for Public Comment
As a result of these preliminary determinations, NMFS proposes to
issue a renewal IHA to MOS for conducting the terminal redevelopment
construction in Skagway, Alaska, from the date of issuance through
