Takes of Marine Mammals Incidental to Specified Activities; 
Taking Marine Mammals Incidental to the Floating Dry Dock Project at 
Naval Base San Diego in San Diego, California

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

ACTION: Notice; issuance of incidental harassment authorization.

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

SUMMARY: NMFS has received a request from the United States Navy for 
the re-issuance of a previously issued incidental harassment 
authorization (IHA) with the only change being effective dates. The 
initial IHA authorized take of one species of marine mammals, by Level 
B harassment, incidental to construction associated with the Floating 
Dry Dock Project at Naval Base San Diego in San Diego, California. The 
project has been delayed and none of the work covered in the initial 
IHA has been conducted. The initial IHA was effective from September 
15, 2020, through September 14, 2021. The Navy has requested re-
issuance with new effective dates of September 15, 2021, through 
September 14, 2022. The scope of the activities and anticipated effects 
remain the same, authorized take numbers are not changed, and the 
required mitigation, monitoring, and reporting remains the same as 
included in the initial IHA. NMFS is, therefore, issuing a second 
identical IHA to cover the incidental take analyzed and authorized in 
the initial IHA.

DATES: This authorization is effective from September 15, 2021, through 
September 14, 2022.

to the Navy, the Navy's application, and the Federal Register notices 
proposing and issuing the initial IHA may be obtained by visiting

SUPPLEMENTARY INFORMATION:

Background

    Sections 101(a)(5)(A) and (D) of the Marine Mammal Protection Act 
(MMPA; 16 U.S.C. 1361 et seq.) direct the Secretary of Commerce (as 
delegated to NMFS) to allow, upon request, the incidental, but not 
intentional, taking of small numbers of marine mammals by U.S. citizens 
who engage in a specified activity (other than commercial fishing) 
within a specified geographical region if certain findings are made and 
either regulations are issued or, if the taking is limited to 
harassment, a notice of a proposed authorization is provided to the 
public for review.
    An authorization for incidental takings shall be granted if NMFS 
finds that the taking will have a negligible impact on the species or 
stock(s), will not have an unmitigable adverse impact on the 
availability of the species or stock(s) for subsistence uses (where 
relevant), and if the permissible methods of taking and requirements 
pertaining to the mitigation, monitoring and reporting of such takings 
are set forth.
    NMFS has defined ``negligible impact'' in 50 CFR 216.103 as an 
impact resulting from the specified activity that cannot be reasonably 
expected to, and is not reasonably likely to, adversely affect the 
species or stock through effects on annual rates of recruitment or 
survival.
    The MMPA states that the term ``take'' means to harass, hunt, 
capture, kill or attempt to harass, hunt, capture, or kill any marine 
mammal.
    Except with respect to certain activities not pertinent here, the 
MMPA defines ``harassment'' as any act of pursuit, torment, or 
annoyance which (i) has the potential to injure a marine mammal or 
marine mammal stock in the wild (Level A harassment); or (ii) has the 
potential to disturb a marine mammal or marine mammal stock in the wild 
by causing disruption of behavioral patterns, including, but not 
limited to, migration, breathing, nursing, breeding, feeding, or 
sheltering (Level B harassment).

Summary of Request

    On June 1, 2020, NMFS published final notice of our issuance of an 
IHA authorizing take of marine mammals incidental to the Floating Dry 
Dock Project at Naval Base San Diego in San Diego, California (85 FR 
33129). The effective dates of that IHA were September 15, 2020, 
through September 14, 2021. On July 12, 2021, the Navy informed NMFS 
that the project was delayed. None of the work identified in the 
initial IHA (e.g., pile driving) has occurred. The Navy submitted a 
request that we reissue an identical IHA that would be effective from 
September 15, 2021, through September 14, 2022, in order to conduct the 
construction work that was analyzed and authorized through the 
previously issued IHA. Therefore, re-issuance of the IHA is 
appropriate.

Summary of Specified Activity and Anticipated Impacts

    The planned activities (including mitigation, monitoring, and 
reporting), authorized incidental take, and anticipated impacts on the 
affected stocks are the same as those analyzed and authorized through 
the previously issued IHA.
    The purpose of the Navy's construction project is to ensure the 
Naval Base San Diego's capability to conduct berth-side repair and 
maintenance of vessels. The need for the proposed action is to 
construct a floating dry dock by support by installing two mooring 
dolphins, fender piles, and a concrete ramp wharf and vehicle bridge. 
The location, timing, and nature of the activities, including the types 
of equipment planned for use, are identical to those described in the 
initial IHA. The mitigation and monitoring are also as prescribed in 
the initial IHA.
    The only species that is expected to be taken by the planned 
activity is California sea lions (Zalophus

[[Page 40469]]

californianus). A description of the methods and inputs used to 
estimate take anticipated to occur and, ultimately, the take that was 
authorized is found in the previous documents referenced above. The 
data inputs and methods of estimating take are identical to those used 
in the initial IHA. NMFS has reviewed recent Stock Assessment Reports, 
information on relevant Unusual Mortality Events, and recent scientific 
literature, and determined that no new information affects our original 
analysis of impacts or take estimate under the initial IHA.
    We refer to the documents related to the previously issued IHA, 
which include the Federal Register notice of the issuance of the 
initial 2020 IHA for the Navy's construction work (85 FR 33129; June 1, 
2020), the Navy's application, the Federal Register notice of the 
proposed IHA (85 FR 21179; April 16, 2020), and all associated 
references and documents.

Determinations

    The Navy will conduct activities as analyzed in the initial 2020 
IHA. As described above, the number of authorized takes of the same 
species and stocks of marine mammals are identical to the numbers that 
were found to meet the negligible impact and small numbers standards 
and authorized under the initial IHA and no new information has emerged 
that would change those findings. The re-issued 2021 IHA includes 
identical required mitigation, monitoring, and reporting measures as 
the initial IHA, and there is no new information suggesting that our 
analysis or findings should change.
    Based on the information 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; and (4) the Navy'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.

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 with respect to environmental 
consequences on the human environment.
    Accordingly, NMFS has determined that the issuance of the IHA 
qualifies to be categorically excluded from further NEPA review. This 
action is consistent with categories of activities identified in CE 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.

Endangered Species Act (ESA)

    Section 7(a)(2) of the Endangered Species Act of 1973 (ESA: 16 
U.S.C. 1531 et seq.) requires that each Federal agency insure that any 
action it authorizes, funds, or carries out is not likely to jeopardize 
the continued existence of any endangered or threatened species or 
result in the destruction or adverse modification of designated 
critical habitat. To ensure ESA compliance for the issuance of IHAs, 
NMFS consults internally whenever we propose to authorize take for 
endangered or threatened species.
    However, no incidental take of ESA-listed species is authorized or 
expected to result from this activity. Therefore, NMFS has determined 
that formal consultation under section 7 of the ESA is not required for 
this action.

Authorization

    NMFS has issued an IHA to the Navy for in-water construction 
activities associated with the specified activity from September 15, 
2020, through September 14, 2021. All previously described mitigation, 
monitoring, and reporting requirements from the initial 2020 IHA are 
incorporated.

    Dated: July 22, 2021.

Acting Director, Office of Protected Resources, National Marine 
Fisheries Service.
