Takes of Marine Mammals Incidental to Specified Activities; 
Taking Marine Mammals Incidental to the Terminal 4 Expansion and 
Redevelopment Project at the Port of Grays Harbor, Washington

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Notice; request for comments on proposed renewal incidental 
harassment authorization.

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

SUMMARY: NMFS received a request from the Port of Grays Harbor (Port) 
for the renewal of a currently active incidental harassment 
authorization (IHA) to take marine mammals incidental to construction 
activities associated with the Terminal 4 (T4) Expansion and 
Redevelopment Project (Project) at the Port of Grays Harbor in Grays 
Harbor County, Washington. The Port's activities will not be completed 
prior to the IHA's 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.

DATES: Comments and information must be received no later than July 16, 
2025.

ADDRESSES: Comments should be addressed to the Permits and Conservation 
Division, Office of Protected Resources, National Marine Fisheries 
Service, and should be submitted via email to [email protected]. 
Electronic copies of the original application, renewal request, and 
supporting documents (including NMFS Federal Register notices of the 
original proposed and final authorizations, and the previous IHA), as 
well as a list of the references cited in this document, may be 
obtained online at: https://www.fisheries.noaa.gov/action/incidental-take-authorization-ag-processing-incs-port-grays-harbor-terminal-4-expansion-and. In case of problems accessing these documents, please

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 proposed or, if the taking is limited to harassment, a notice of a 
proposed IHA 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''); and requirements pertaining to the monitoring and 
reporting of the takings. The definition of all applicable MMPA 
statutory used above are included in the relevant sections below and 
can be found in section 3 of the MMPA (16 U.S.C. 1362) and the NMFS's 
implementing 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 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:
     An explanation that the activities to be conducted under 
the requested renewal IHA are identical to the activities analyzed 
under the initial IHA, are a subset of the activities, or include 
changes so minor (e.g., reduction in pile size) that the changes do not 
affect the previous analyses, mitigation and monitoring requirements, 
or take estimates (with the exception of reducing the type or amount of 
take); and
     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: https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals. 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 a renewal 
IHA) 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 June 7, 2024, NMFS issued an IHA to Ag Processing Inc. (AGP) to 
take marine mammals incidental to construction activities associated 
with the Terminal 4 (T4) Expansion and Redevelopment Project (Project) 
at the Port of Grays Harbor (Port) in both the City of Aberdeen and 
City of Hoquiam, Grays Harbor County, Washington (89 FR 48565), 
effective from July 16, 2024 through July 15, 2025. Note that this

[[Page 28727]]

Project is a joint effort between the Port and AGP. The initial IHA was 
issued to AGP but the Port is requesting to be the holder of the 
proposed renewal authorization. On April 16, 2025, NMFS received an 
application for the renewal of that initial IHA from the Port. As 
described in the application for renewal IHA, the activities for which 
incidental take is requested are consistent with activities that are 
covered by the initial authorization but will not be completed prior to 
its expiration. As required, AGP also provided a preliminary monitoring 
report which confirms that it 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

    The purpose of the project is to construct a new export facility at 
Terminal 4 (T4). The activity includes removal of existing piles and 
the installation of both temporary and permanent piles of various 
sizes. Takes of marine mammals by Level A and Level B harassment are 
expected to occur as a result of noise produced by both impact and 
vibratory pile driving and vibratory removal. The initial IHA 
authorized take incidental to in-water construction activities 
associated with the installation of a new fendering system at Terminal 
4A and the installation of a new commodity export facility at Terminal 
4B. AGP has completed the in-water construction activities for the new 
commodity export facility at Terminal 4B. However, a one-year renewal 
of the initial IHA is needed to complete the in-water construction 
activities associated with the new fendering system at Terminal 4A.

Detailed Description of the Activity

    A detailed description of the demolition and construction 
activities for which take is proposed here may be found in the Notices 
of the Proposed (89 FR 24436, April 8, 2024) and Final (89 FR 48565, 
June 7, 2024) IHAs for the initial authorization. The location, timing, 
and nature of the activities, including the types of equipment planned 
for use, are similar to those described in the previous notices. The 
proposed renewal would be effective for a period not exceeding 1 year 
from the date of expiration of the initial IHA.
    The existing IHA authorizes take incidental to the in-water pile 
driving/removal activities shown in tables 1 and 2. The activities in 
table 1 are proposed to be completed under this renewal IHA and the 
activities in table 2 were completed under the initial IHA. The 
previously planned impact proofing of 24-inch (60.96 centimeter (cm)) 
steel pipe piles was not required at Terminal 4B. Since the impact 
proofing of 24-inch (60.96 cm) steel pipe piles planned for the 
Terminal 4B commodity export facility portion of the Project was not 
required, the Port intends to conduct similar impact proofing for the 
fendering system construction at Terminal 4A under the proposed renewal 
IHA. With the exception of impact proofing for the new fendering 
system, the Port did not propose any new activities or modifications 
from the originally proposed actions. Pile removal and installation 
activities are anticipated to occur during the in-water work window 
(July 16 through February 15). The most conservative estimate of time 
required to complete pile installation and removal activities under 
this renewal is 36 days of intermittent vibratory pile driving/removal 
and an additional 8 days of impact proofing.

  the proposed renewal and has been applied to pile installation activities in table 1.

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 
Notices of the Proposed IHA for the initial authorization (89 FR 24436, 
April 8, 2024). NMFS has reviewed the monitoring data from the initial 
IHA, recent draft Stock

[[Page 28728]]

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 (89 FR 24436, April 8, 2024). 
Note that the abundance estimate for the Oregon/Washington coastal 
stock of harbor seal has been updated to 22,549 from 24,731 animals 
based on more recent best available information (Pearson et al. 2024), 
but this does not impact estimated take numbers under the proposed 
renewal or influence the findings made in support of 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 an 
authorization of incidental take is proposed here may be found in the 
notices of the proposed IHA for the initial authorization (89 FR 24436, 
April 8, 2024). 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

    A detailed description of the methods used to estimate take for the 
specified activity are found in the notices of the proposed and final 
IHAs for the initial authorization (89 FR 24436, April 8, 2024; 89 FR 
48565, June 7, 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 IHA. However, there are changes to the estimated Level 
A harassment zones based on the 2024 Updated 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 for the proposed renewal was 
calculated using the same methodology as in the initial proposed and 
final IHAs (89 FR 24436, April 8, 2024; 89 FR 48565, June 7, 2024).
    On October 24, 2024 NMFS published (89 FR 84872) its final Updated 
Technical Guidance (https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-acoustic-technical-guidance-other-acoustic-tools) which includes updated thresholds and weighting 
functions to inform auditory injury estimates and is replacing the 2018 
Technical Guidance referenced in the notices of the proposed and final 
IHAs for the initial authorization (89 FR 24436, April 8, 2024; 89 FR 
48565, June 7, 2024). In consideration of the best available science, 
NMFS conducted calculations using the Updated Technical Guidance and 
NMFS optional user spreadsheet, using the source levels and spreadsheet 
inputs provided in the notices for the proposed and final IHAs (89 FR 
24436, April 8, 2024; 89 FR 48565, June 7, 2024), for the purpose of 
understanding how Level A harassment (auditory injury) zones might 
change from the initial IHA. The updated marine mammal hearing groups 
and updated thresholds can be found in tables 3 and 4.

* Dual metric thresholds for impulsive sounds: Use whichever results in the largest isopleth for calculating AUD
  INJ onset. If a non-impulsive sound has the potential of exceeding the peak sound pressure level thresholds
  associated with impulsive sounds, these thresholds are recommended for consideration.

[[Page 28729]]

 
Note: Peak sound pressure level (L0-pk) has a reference value of 1 [micro]Pa, and weighted cumulative sound
  exposure level (LE,) has a reference value of 1[micro]Pa\2\s. In this table, thresholds are abbreviated to be
  more reflective of International Organization for Standardization standards (ISO 2017). The subscript ``flat''
  is being included to indicate peak sound pressure are flat weighted or unweighted within the generalized
  hearing range of marine mammals (i.e., 7 Hz to 165 kHz). The subscript associated with cumulative sound
  exposure level thresholds indicates the designated marine mammal auditory weighting function (LF, HF, and VHF
  cetaceans, and PW and OW pinnipeds) and that the recommended accumulation period is 24 hours. The weighted
  cumulative sound exposure level thresholds could be exceeded in a multitude of ways (i.e., varying exposure
  levels and durations, duty cycle). When possible, it is valuable for action proponents to indicate the
  conditions under which these thresholds will be exceeded.

    The inputs contained in the 2018 Technical Guidance user 
spreadsheet for the initial IHA are identical to those utilized in the 
2024 Technical Guidance user spreadsheet. However, the estimated Level 
A harassment isopleths have increased in some cases when the updated 
2024 Technical Guidance is used as shown in table 5. The Port proposes 
to change the shutdown zones accordingly and consistent with the intent 
of the measures prescribed through the initial IHA, as discussed in 
Description of Proposed Mitigation, Monitoring and Reporting Measures 
section.

    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/or Final IHAs (89 FR 24436, April 8, 2024; 89 FR 48565, 
June 7, 2024) for the initial authorization. Specifically, the source 
levels, days of operation, and marine mammal density/occurrence data 
applicable to this authorization remain unchanged from the previously 
issued IHA. The sizes of the estimated Level A harassment zones have 
changed in some cases as shown in table 5 and these are reflected in 
tables 6-11. The stocks taken, methods of take, and types of take 
remain unchanged from the previously issued IHA. The estimated number 
of takes for the proposed renewal were calculated by adding the 
individual takes associated with each of the activities listed in table 
5. Tables 6-11 show calculated take numbers by Level A (where 
authorized) and Level B harassment.

Description of Proposed Mitigation, Monitoring and Reporting Measures

    The proposed mitigation, monitoring, and reporting measures 
included as requirements in this renewal authorization are similar to 
those included in the Federal Register notice announcing the issuance 
of the initial IHA (89 FR 48565, June 7, 2024), and the discussion of 
the least practicable adverse impact included in that document and the 
Notice of the Proposed IHA (89 FR 24436, April 8, 2024) remain 
accurate. The following measures are proposed for this renewal:
     The Port must employ NMFS-approved protected Species 
Observers (PSOs) and establish monitoring locations to the maximum 
extent possible based on the required number of PSOs, required 
monitoring locations, and environmental conditions;
     Monitoring must take place from 30 minutes prior to 
initiation of pile driving activity (i.e., pre-start clearance 
monitoring) through 30 minutes post-completion of pile driving 
activity;
     Pre-start clearance monitoring must be conducted during 
periods of visibility sufficient for the lead PSO to determine that the 
shutdown zones are clear of marine mammals;
     If a marine mammal is observed entering or within the 
shutdown zones pile driving activity must be delayed or halted;
     If pile driving 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;
     Soft start techniques must be used when impact pile 
driving;
     A bubble curtain must be used during impact pile driving;
     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;
     The Port must shut down construction operations if a 
marine mammal comes within 10 m of construction activity to avoid 
direct physical interaction with marine mammals;
     The Port must submit a draft marine mammal monitoring 
report to NMFS within 90 days after the completion of pile driving 
activities or 60 calendar days prior to the requested issuance of any 
subsequent IHA for construction activity at the same location, 
whichever comes first. A final report must be prepared and submitted 
within 30 calendar days following receipt of any NMFS comments on the 
draft report; and
     All injured or dead marine mammals must be reported to the 
Office of Protected Resources and to the West Coast regional stranding 
network.
    Consistent with the mitigation required through the initial IHA, 
shutdown zones proposed for the renewal IHA will be based on the 
largest Level A harassment zone for each pile size/type and driving 
method, as updated using the draft 2024 Technical Guidance rather than 
the 2018 Technical Guidance. Proposed zones are shown in table 13.

* In the 2018 guidance and initial IHA, VHF cetaceans were referred to as HF (high-frequency) cetaceans.
** Represents change from Initial 2024-2025 IHA. Initial zones in parentheses.

    The monitoring zones in the proposed renewal are identical to those 
found in the initial proposed and final IHAs (89 FR 24436, April 8, 
2024; 89 FR 48565, June 7, 2024). Most of the Level A harassment zones 
remain unchanged from the initial proposed and final IHAs. However, the 
Level A harassment zone for Otariids during impact installation of 24-
inch (60.96 cm) steel piles increased from 12 m to 97 m so the shutdown 
zone was increased to 100 m. Vibratory removal of 18-in creosote timber 
piles for Otariids increased from 1 m to 14 m so the shutdown zone was 
increased to 15 m from the previous 10 m minimum.

Comments and Responses

    As noted previously, NMFS published a notice of a proposed IHA (89 
FR 24436; May 8, 2024) and solicited public comments on both our 
proposal to issue the initial IHA for construction activities 
associated with the Project and on the potential for a renewal IHA, 
should certain requirements be met.
    All public comments were addressed in the notice announcing the 
issuance of the initial IHA (89 FR 48565; June 7, 2024) and none of the 
comments specifically pertained to the renewal of the 2024 IHA.

Preliminary Determinations

    The Port's action will require completing a subset of pile driving 
activities that were not completed under the initial IHA. Work at 
Terminal 4B has been completed while work at Terminal 4A has yet to 
begin. The method of taking and effects of the work on Terminal 4A were 
analyzed in the initial IHA along with Terminal B. Work on both 
terminals was expected to take 105 days under the initial IHA. The Port 
estimates that only 44 days of work remain. The take estimate for the 
renewal IHA is based on the activities proposed to occur during these 
remaining days. The proposed renewal take numbers represent a subset of 
the total take authorized under the initial IHA. In analyzing the 
effects of the activities for the initial IHA, NMFS determined that the 
Port'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 the initial IHA, 
although some shutdown zones for Otariids have undergone slight 
revisions due to the Updated 2024 Technical Guidance. The abundance of 
a single species (OR/WA coast stock of harbor seals) has also changed 
since the initial IHA, but none of this new information affects NMFS' 
determinations supporting issuance of the initial IHA. The piles to be 
driven in the proposed subset of work and any 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 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 Port'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

    Section 7(a)(2) of the Endangered Species Act of 1973 (ESA: 16 
U.S.C. 1531 et seq.) requires that each Federal agency ensure 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 proposed for 
authorization 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 proposed action.

Proposed Renewal IHA and Request for Public Comment

    As a result of these preliminary determinations, NMFS proposes to 
issue a renewal IHA to the Port for conducting construction activities 
as part of the T4 Expansion and Redevelopment Project at the Port of 
Grays Harbor in both the City of Aberdeen and City of Hoquiam, Grays 
Harbor County, Washington from July 16, 2025 through July 15, 2026, 
provided the previously described mitigation, monitoring, and reporting 
requirements are incorporated. A draft of the proposed and final 
initial IHA can

be found at https://www.fisheries.noaa.gov/action/incidental-take-authorization-ag-processing-incs-port-grays-harbor-terminal-4-expansion-and. We request comment on our analyses, the proposed renewal 
IHA, and any other aspect of this notice. Please include with your 
comments any supporting data or literature citations to help inform our 
final decision on the request for this renewal IHA.
