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 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 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 cannot extend beyond one 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: www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals.

History of Request

    On September 3, 2020, NMFS issued an IHA to WSDOT to take marine 
mammals incidental to the fourth year of work associated with the 
Seattle Multimodal Project at Colman Dock in Seattle, Washington (85 FR 
59737; September 23, 2020), effective from September 10, 2020 through 
September 9, 2021. The initial IHA covered one year of the larger 
project for which WSDOT obtained prior IHAs (82 FR 31579, July 7, 2017; 
83 FR 35226, July 25, 2018; 84 FR 36581, July 29, 2019). On March 18, 
2021, 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 https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-construction-activities) 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 incidental harassment authorization was 
published on June 23, 2021 (86 FR 32895).

Description of the Specified Activities and Anticipated Impacts

    WSDOT has requested incidental take for construction activities 
related to the Seattle Multimodal Project at Colman Dock in Seattle, 
Washington State. The activities addressed in this request represent a 
subset of the activities analyzed in the initial IHA, consisting of 
vibratory pile removal only, and are identical to the activities 
described in the initial IHA.
    Accordingly the authorized take is for the same 11 species 
authorized in the initial IHA (see Table 4), and the amount of take is 
reflective of the take estimation methods described in the initial IHA 
applied to the remaining work described below.
    The following documents are referenced in this notice and include 
important supporting information:
    <bullet> Initial 2020 final IHA (85 FR 59737; September 23, 2020);
    <bullet> Initial 2020 proposed IHA (85 FR 40992; July 8, 2020); and
    <bullet> Initial IHA application, references cited, marine mammal 
monitoring plan, preliminary monitoring report, and previous public 
comments received (available at https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-take-authorizations-construction-activities).

Detailed Description of the Activity

    A detailed description of the pile installation and removal 
activities for which take was authorized in the initial IHA may be 
found in the Federal Register notices of the proposed and final IHA for 
the initial authorization (85 FR 40992, July 8, 2020; 85 FR 59737, 
September 23, 2020). Only a subset of the construction activities 
remain to be

[[Page 38688]]

conducted, and 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.
    Below and in Table 1 we describe the specific in-water pile driving 
and pile removal activities that were planned and already occurred 
under the initial IHA and those that remain to be completed under this 
renewal IHA:
    <bullet> Vibratory driving followed by impact proofing (driving) of 
36-inch steel piles. A total of 73 piles were installed using the 
vibratory hammer over 9 days, with an average of approximately 8 piles 
installed per day. Vibratory pile driving and impact proofing occurred 
on different days;
    <bullet> Vibratory driving and then removal of 24-inch temporary 
steel piles. A total of 30 piles were planned be installed and later 
removed, with an average of 8 piles installed/removed per day;
    <bullet> Vibratory removal of 355 14-inch timber piles over 18 
days, with approximately 20 piles removed per day; and
    <bullet> Vibratory removal of 30 12-inch steel piles over 3 days, 
with 10 piles removed per day.
    All vibratory and impact pile installation was completed. Only 
vibratory removal of timber and temporary steel piles remains to be 
completed (Table 1).

* These are same piles.

    The total estimated duration of pile driving activities planned in 
the initial IHA was 47 days. In consideration of the time required to 
remove each pile using a vibratory hammer and the number of piles that 
may be removed per day, a total of 8 days of work remain to remove the 
rest of the timber piles and temporary steel piles (Table 2).
    Due to NMFS and U.S. Fish and Wildlife Service (USFWS) in-water 
work timing restrictions to protect Endangered Species Act (ESA)-listed 
salmonids, planned WSDOT in-water construction is limited each year to 
July 15 through February 15 at this location. For this project, in-
water construction is planned to take place between August 1, 2021 and 
February 15, 2022. This IHA Renewal is effective from August 1, 2021 
through July 31, 2022.

Description of Marine Mammals

    A description of the marine mammals in the area of the activities 
for which authorization of take is authorized here, including 
information on abundance, status, distribution, and hearing, may be 
found in the Federal Register notice of proposed IHA for the initial 
authorization (85 FR 40992; July 8, 2020) and the Federal Register 
notice of proposed IHA for the Year 3 Seattle Multimodal Project at 
Colman Dock (84 FR 25757; June 4, 2019). 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 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 proposed 
IHA for the initial authorization (85 FR 40992; July 8, 2020). NMFS has 
reviewed the monitoring data from the initial 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 Federal Register 
notices of proposed IHA (85 FR 40992; July 8, 2020) and final IHA (85 
FR 59737; September 23, 2020) for the initial authorization. 
Specifically, the source levels, corresponding Level A and Level B 
harassment zones (in m) and ensonified areas (in square kilometers 
(km\2\); Table 3), and marine mammal density/occurrence data applicable 
to this authorization remain unchanged from the previously issued IHA. 
Similarly, the stocks taken, methods of take, and types of take remain 
unchanged from

[[Page 38689]]

the previously issued IHA. The only change from the methods used to 
estimate take in the initial IHA is the total duration (days) of pile 
driving activities, which has been reduced from a total of 47 days of 
activities, occurring over the course of 7 months, in the initial IHA 
to 8 days of remaining activities estimated to occur within one month.

LF = low-frequency; MF = mid-frequency; HF = high-frequency.

    Authorized takes are by Level B harassment only, as use of the 
vibratory hammer has the potential to result in disruption of 
behavioral patterns for individual marine mammals. The initial IHA 
authorized take of harbor seals and harbor porpoises by Level A 
harassment from impact pile driving. However, as described in the 
initial IHA, based on the nature of the activity remaining in this 
Renewal (vibratory pile driving) and the anticipated effectiveness of 
the mitigation measures (i.e., shutdown, see Proposed Mitigation 
below), Level A harassment is neither anticipated from vibratory pile 
driving and is not authorized here.
    As described in the initial IHA, the initial approach for take 
calculation was to use the information aggregated in the U.S. Navy 
Marine Species Density Database (U.S. Navy, 2019) with the following 
equation:

Total Take = marine mammal density x ensonified area x pile driving 
days

    However, also as described in the initial IHA, adjustments were 
made to all of these initial estimates based on prior observation of 
marine mammals in the project area and account for group numbers, and 
in fact most estimates were based on a predicted number of individuals 
entering the Level B harassment zone per month, with several estimates 
also based on a predicted number entering per day. Take estimates for 
the activities remaining in this renewal IHA were developed using the 
identical methods as the initial IHA, in consideration of the remaining 
8 days of work, and equated to one month where monthly estimates were 
used. Table 4 indicates the number of each species or stock proposed 
for authorization.

    We have reviewed the preliminary monitoring report submitted by 
WSDOT and the monitoring results do not indicate impacts of a scale or 
nature not previously analyzed or authorized and, therefore, these 
estimates are appropriate.

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 
(85 FR 59737; September 23, 2020), with the exception of mitigation 
measures specific to impact pile driving, which will not occur under 
this IHA. The discussion of the least practicable adverse impact 
included in that document remains accurate. The following measures are 
required in this Renewal:
Proposed Mitigation
    Time Restriction--The applicant stated that work would occur only 
during daylight hours, when visual monitoring of marine mammals can be 
conducted. In addition, all in-water construction will be limited to 
the period between August 1, 2021, and February 15, 2022.
    Establishing and Monitoring Level A, Level B Harassment Zones, and 
Exclusion Zones--Before the commencement of in-water construction 
activities, which include vibratory pile removal, WSDOT must establish 
Level A harassment zones where received underwater sound pressure 
levels (SPLs) or cumulative sound exposure levels (SEL<INF>cum</INF>) 
could cause permanent threshold shift (PTS).
    WSDOT must also establish Level B harassment zones where received 
underwater SPLs are higher than 120 decibels root-mean-square 
(dB<INF>rms</INF>) re 1 microPascal ([micro]Pa) for continuous noise 
sources (e.g., vibratory pile removal).
    WSDOT must establish exclusion zones as shown in Table 5 to prevent

[[Page 38690]]

Level A harassment takes of all marine mammal hearing groups.
    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.
    WSDOT must establish exclusion zones for Southern Resident killer 
whales (SRKW) and all marine mammals for which takes are not authorized 
at the Level B harassment distances. Specifically, for vibratory 
removal of 24-inch steel piles, an 8.7 km exclusion zone must be 
established. For vibratory removal of 14-inch timber piles, a 2.2 km 
exclusion zone must be established.
    A summary of exclusion zones is provided in Table 5.

    NMFS-approved protected species observers (PSOs) must conduct an 
initial survey of the exclusion zones to ensure that no marine mammals 
are seen within the zones beginning 30 minutes before removal of a pile 
segment begins. If marine mammals are found within the exclusion zone, 
pile driving of the segment must be delayed until they move out of the 
area. If a marine mammal is seen above water and then dives below, the 
contractor must wait 15 minutes. If no marine mammals are seen by the 
observer in that time it can be assumed that the animal has moved 
beyond the exclusion zone.
    If pile driving of a segment ceases for 30 minutes or more and a 
marine mammal is sighted within the designated exclusion zone prior to 
commencement of pile removal, the observer(s) must notify the pile 
driving operator (or other authorized individual) immediately and 
continue to monitor the exclusion zone. Operations may not resume until 
the marine mammal has exited the exclusion zone or 15 minutes have 
elapsed since the last sighting.
    Shutdown Measures--WSDOT must implement shutdown measures if a 
marine mammal is detected within or entering an exclusion zone listed 
in Table 5.
    WSDOT must also implement shutdown measures if SRKW are sighted 
within the vicinity of the project area and are approaching the Level B 
harassment zone during in-water construction activities.
    If a killer whale approaches the Level B harassment zone during 
pile driving or removal, and it is unknown whether it is a SRKW or a 
transient killer whale, it must be assumed to be a SRKW and WSDOT must 
implement the shutdown measure.
    If a SRKW or an unidentified killer whale enters the Level B 
harassment zone undetected, in-water pile driving or pile removal must 
be suspended until the whale exits the Level B harassment zone, or 15 
minutes have elapsed with no sighting of the animal, to avoid further 
Level B harassment.
    Further, WSDOT must implement shutdown measures if the number of 
authorized takes for any particular species reaches the limit under the 
IHA and if such marine mammals are sighted within the vicinity of the 
project area and are approaching the Level B harassment zone during in-
water construction activities.
    Coordination with Local Marine Mammal Research Network--Prior to 
the start of pile driving for the day, WSDOT must contact the Orca 
Network and/or Center for Whale Research to find out the location of 
the nearest marine mammal sightings. The Local Marine Mammal Research 
Network consists of a list of over 600 (and growing) residents, 
scientists, and government agency personnel in the United States and 
Canada. Sightings are called or emailed into the Orca Network and 
immediately distributed to other sighting networks including: The NMFS 
Northwest Fisheries Science Center, the Center for Whale Research, 
Cascadia Research, the Whale Museum Hotline and the British Columbia 
Sightings Network.
    Sightings information collected by the Orca Network includes 
detection by hydrophone. The SeaSound Remote Sensing Network is a 
system of interconnected hydrophones installed in the marine 
environment of Haro Strait (west side of San Juan Island) to study orca 
communication, in-water noise, bottom fish ecology and local climatic 
conditions. A hydrophone at the Port Townsend Marine Science Center 
measures average in-water sound levels and automatically detects 
unusual sounds. These passive acoustic devices allow researchers to 
hear when different marine mammals come into the region. This acoustic 
network, combined with the volunteer (incidental) visual sighting 
network allows researchers to document presence and location of various 
marine mammal species.
Proposed Monitoring and Reporting
    Monitoring Measures--WSDOT must employ NMFS-approved PSOs to 
conduct marine mammal monitoring for its Seattle Multimodal Project at 
Colman Dock. The PSOs must observe and collect data on marine mammals 
in and around the project area for 30 minutes before, during, and for 
30 minutes after all pile removal and pile installation work. NMFS-
approved PSOs must meet the following requirements:
    1. Independent observers (i.e., not construction personnel) are 
required;
    2. At least one observer must have prior experience working as an 
observer;
    3. Other observers may substitute education (undergraduate degree 
in biological science or related field) or training for experience;
    4. Where a team of three or more observers are required, one 
observer should be designated as lead observer or monitoring 
coordinator. The lead observer must have prior experience working as an 
observer; and
    5. NMFS will require submission and approval of observer Curriculum 
Vitas.
    Monitoring of marine mammals around the construction site must be 
conducted using high-quality binoculars (e.g., Zeiss, 10 x 42 power). 
Due to the different sizes of zones of influence (ZOIs) from different 
pile sizes, several different ZOIs and different monitoring protocols 
corresponding to a specific pile size will be established. During 
vibratory removal of 24-inch steel piles, four land-based PSOs and one 
ferry-based PSO must monitor the zone. During vibratory removal of 14-
inch

[[Page 38691]]

timber piles, four land-based PSOs must monitor the zone. Locations of 
the land-based PSOs and routes of monitoring vessels are shown in 
WSDOT's Marine Mammal Monitoring Plan, which is available online at 
https://www.fisheries.noaa.gov/permit/incidental-take-authorizations-under-marine-mammal-protection-act.
    To verify the required monitoring distance, the exclusion zones and 
zones of influence must be determined by using a range finder or hand-
held global positioning system device.
    Reporting Measures--WSDOT is required to submit a draft report on 
all marine mammal monitoring conducted under the IHA (if issued) within 
90 calendar days of the completion of the project. A final report must 
be prepared and submitted within 30 days following resolution of 
comments on the draft report from NMFS.
    The marine mammal report must contain the informational elements 
described in the Marine Mammal Monitoring Plan for the initial IHA, 
dated May 12, 2020, including, but not limited to:
    1. Dates and times (begin and end) of all marine mammal monitoring;
    2. Construction activities occurring during each daily observation 
period, including how many and what type of piles were driven or 
removed;
    3. Weather parameters and water conditions during each monitoring 
period (e.g., wind speed, percent cover, visibility, sea state);
    4. 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;
    5. Age and sex class, if possible, of all marine mammals observed;
    6. PSO locations during marine mammal monitoring;
    7. 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);
    8. Description of any marine mammal behavior patterns during 
observation, including direction of travel and estimated time spent 
within the Level B harassment zones while the source was active;
    9. Number of individuals of each species (differentiated by month 
as appropriate) detected within the monitoring zone;
    10. 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;
    11. 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; and
    12. 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, WSDOT must report the 
incident to the Office of Protected Resources (OPR) (301-427-8401), 
NMFS and to the West Coast Region (WCR) regional stranding coordinator 
(1-866-767-6114) as soon as feasible. If the death or injury was 
clearly caused by the specified activity, WSDOT 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. WSDOT must 
not resume their activities until notified by NMFS.
    The report must include the following information:
    1. Time, date, and location (latitude/longitude) of the first 
discovery (and updated location information if known and applicable);
    2. Species identification (if known) or description of the 
animal(s) involved;
    3. Condition of the animal(s) (including carcass condition if the 
animal is dead);
    4. Observed behaviors of the animal(s), if alive;
    5. If available, photographs or video footage of the animal(s); and
    6. General circumstances under which the animal was discovered.

Comments and Responses

    A notice of NMFS' proposal to issue a Renewal IHA to WSDOT was 
published in the Federal Register on June 23, 2021 (86 FR 32895). That 
notice either described, or referenced descriptions of, WSDOT'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 construction activities planned by WSDOT are a subset of, and 
identical to, those analyzed in the initial IHA, and the method of 
taking and the effects of the action are identical to the initial IHA 
(though the amount of proposed authorized take is notably lower). The 
potential effects of WSDOT's activities are limited to Level B 
harassment in the form of behavioral disturbance. In analyzing the 
effects of the activities in the 2020 IHA, NMFS determined that WSDOT'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 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) WSDOT'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 evaluate our proposed action (i.e., the issuance of 
an IHA Renewal) and alternatives with respect to potential impacts on 
the human environment. This action is consistent with categories of 
activities identified in Categorical Exclusion B4 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 has determined that the proposed action 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

[[Page 38692]]

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, in this case with the West Coast Region Protected Resources 
Division, whenever we propose to authorize take for endangered or 
threatened species.
    The only species listed under the ESA with the potential to be 
present in the action area are the Mexico Distinct Population Segment 
(DPS) and Central America DPS of humpback whales. The effects of this 
Federal action were adequately analyzed in NMFS' Biological Opinion for 
the Seattle Multimodal Project at Colman Dock, Seattle, Washington, 
dated October 1, 2018, which concluded that issuance of an IHA would 
not jeopardize the continued existence of any endangered or threatened 
species or destroy or adversely modify any designated critical habitat.

Renewal

    NMFS has issued a Renewal IHA to WSDOT for the take of marine 
mammals incidental to conducting the Seattle Multimodal Project at 
Colman Dock Year 4 in Washington State, between August 1, 2021 and July 
31, 2022.

    Dated: July 16, 2021.

Fisheries Service.
