Taking and Importing Marine Mammals; U.S. Navy's Research, 
Development, Test, and Evaluation Activities Within the Naval Sea 
Systems Command Naval Undersea Warfare Center Keyport Range Complex

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

ACTION: Final rule.

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

SUMMARY: NMFS, upon application from the U.S. Navy (Navy), is issuing 
regulations to govern the unintentional taking of marine mammals 
incidental to activities conducted at the Naval Sea Systems Command 
(NAVSEA) Naval Undersea Warfare Center (NUWC) Keyport Range Complex for 
the period of April 2011 through April 2016. The Navy's activities are 
considered military readiness activities pursuant to the Marine Mammal 
Protection Act (MMPA), as amended by the National Defense Authorization 
Act for Fiscal Year 2004 (NDAA). These regulations, which allow for the 
issuance of ``Letters of Authorization'' (LOAs) for the incidental take 
of marine mammals during the described activities and specified 
timeframes, prescribe the permissible methods of taking and other means 
of effecting the least practicable adverse impact on marine mammal 
species and their habitat, as well as requirements pertaining to the 
monitoring and reporting of such taking.

DATES: Effective April 11, 2011 through April 11, 2016.

ADDRESSES: A copy of the Navy's application (which contains a list of 
the references used in this document), NMFS' Record of Decision (ROD), 
and other documents cited herein may be obtained by writing to Michael 
Payne, Chief, Permits, Conservation and Education Division, Office of 
Protected Resources, National Marine Fisheries Service, 1315 East-West 
Highway, Silver Spring, MD 20910-3225 or by telephone via the contact

Resources, NMFS, (301) 713-2289, ext. 137.

SUPPLEMENTARY INFORMATION: Extensive Supplementary Information was 
provided in the proposed rule for this activity, which was published in 
the Federal Register on Tuesday, July 7, 2009 (74 FR 32264). This 
information will not be reprinted here in its entirety; rather, all 
sections from the proposed rule will be represented herein and will 
contain either a summary of the material presented in the proposed rule 
or a note referencing the page(s) in the proposed rule where the 
information may be found. Any information that has changed since the 
proposed rule was published will be addressed herein. Additionally, 
this final rule contains a section that responds to the comments 
received during the public comment period.

Background

    Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 et seq.) 
direct the Secretary of Commerce (Secretary) to allow, upon request, 
the incidental, but not intentional taking of marine mammals by U.S. 
citizens who engage in a specified activity (other than commercial 
fishing) during periods of not more than five consecutive years each if 
certain findings are made and regulations are issued or, if the taking 
is limited to harassment, notice of a proposed authorization is 
provided to the public for review.
    Authorization 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, and if the permissible methods of taking 
and requirements pertaining to the mitigation, monitoring and reporting 
of such taking 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 NDAA (Pub. L. 108-136) removed the ``small numbers'' and 
``specified geographical region'' limitations and amended the 
definition of ``harassment'' as it applies to a ``military readiness 
activity'' to read as follows (Section 3(18)(B) of the MMPA): Any act 
that injures or has the significant potential to injure a marine mammal 
or marine mammal stock in the wild [Level A Harassment]; or any act 
that disturbs or is likely to disturb a marine mammal or marine mammal 
stock in the wild by causing disruption of natural behavioral patterns, 
including, but not limited to, migration, surfacing, nursing, breeding, 
feeding, or sheltering, to a point where such behavioral patterns are 
abandoned or significantly altered [Level B Harassment].

Summary of Request

    On May 15, 2008, NMFS received an application from the Navy 
requesting authorization for the take of 5 species of marine mammals 
incidental to the RDT&E activities within the NAVSEA NUWC Keyport Range 
Complex Extension over the course of 5 years. These RDT&E activities 
are classified as military readiness activities. On April 29, 2009, 
NMFS received additional information and clarification on the Navy's 
proposed NAVSEA NUWC Keyport Range Complex Extension RDT&E activities. 
The Navy states that these RDT&E activities may cause various impacts 
to marine mammal species in the proposed action area. The Navy requests 
an authorization to take individuals of these marine mammals by Level B 
Harassment. Please refer to Tables 6-23, 6-24, 6-25, and 6-26 of the 
Navy's Letter of Authorization (LOA) application for detailed 
information of the potential marine mammal exposures from the RDT&E 
activities in the Keyport Range Complex Extension per year. However, 
due to the proposed mitigation and monitoring measures and standard 
range operating procedures in place, NMFS estimates that the take of 
marine mammals is likely to be lower than the amount requested. NMFS 
does not expect any marine mammals to be killed or injured as a result 
of the Navy's proposed activities, and NMFS is not proposing to 
authorize any injury or mortality incidental to the Navy's proposed 
RDT&E activities within the Keyport Range Complex Extension.

Background of Navy Request

    The proposed rule contains a description of the Navy's mission, 
their responsibilities pursuant to Title 10 of the United States Code, 
and the specific purpose and need for the activities for which they 
requested incidental take authorization. The description

[[Page 20258]]

contained in the proposed rule has not changed (74 FR 32264; July 7, 
2009; pages 32264-32265).

Description of the Specified Activities

    The proposed rule contains a complete description of the Navy's 
specified activities that are covered by these final regulations, and 
for which the associated incidental take of marine mammals will be 
authorized in the related LOAs. The proposed rule describes the nature 
and levels of the RDT&E activities and the proposed range extension. 
These RDT&E activities consist of testing that involves active acoustic 
devices such as general range tracking, unmanned undersea vehicle (UUV) 
tracking systems, torpedo sonars, range targets and special tests, 
special sonars, sonobuoys and helicopter dipping sonar, side scan 
sonar, and other acoustic sources (acoustic modem, target simulators, 
navigation aids, sub-bottom profilers, and vessel engines, etc.); and 
testing that involves non-acoustic activities such as magnetic, 
oceanographic sensor, laser imaging detection and ranging, and inert 
mine hunting and inert mine clearing exercises. Since NMFS does not 
believe that those range activities involving non-acoustic testing will 
have adverse impacts to marine mammals, they were not analyzed further 
and will not be covered under this rule.
    The proposed regulations were drafted in such a way that the Navy's 
specified actions were strictly defined by the amounts of each type of 
sound source utilized (e.g., hours of source use) over the course of 
the 5-year regulations. Following the issuance of the proposed rule, 
the Navy realized that their evolving RDT&E programs necessitate 
greater flexibility in both the types and amounts of sound sources that 
they use.
    The Navy regularly modifies or develops new technology, often in 
the way of sound sources that are similar to, but not exactly the same 
as, other sources. In this final rule, we increase flexibility by 
inserting language into Sec.  218.170(c) that will allow for 
authorization of take incidental to the previously identified specified 
activities and sources or to ``similar activities and sources,'' 
provided that the implementation of these changes in annual LOAs does 
not result in exceeding the incidental take analyzed and identified in 
the final rules.
    Regarding amounts of sound source use, the proposed regulations 
only allowed for the authorization of take incidental to a 5-yr maximum 
amount of use for each specific sound source, even though in most cases 
our effects analyses do not differentiate the impacts from the majority 
of the different types of sources. Specifically, although some sonar 
sources are louder or put more acoustic energy into the water in a 
given amount of time, which results in more marine mammal takes, we do 
not differentiate between the individual takes that result from one 
source versus another. In this final rule, we increase flexibility by 
including language in Sec.  218.170(c)(2) that allows for inter-annual 
variability in the amount of source use identified in each annual LOA 
(i.e., one year the Navy could use a lot of one source, and little of 
another, and the next year those amounts could be reversed), provided 
it does not result in exceeding the incidental take analyzed and 
identified in the final rules. These technical regulatory modifications 
do not change the analyses conducted in the proposed rule.
    No other changes have been made in this section from the proposed 
rule (74 FR 32264; July 7, 2009; pages 32265-32268). Tables 1 through 4 
summarize the projected days of use by range site, primary acoustic 
sources commonly used within the NAVSEA NUWC Keyport Range Complex and 
their operating hours, and the proposed annual range activities and 
operations, respectively.

Description of Marine Mammals in the Area of the Specified Activities

    The information on marine mammals and their distribution and 
density are based on data gathered from NMFS, United States Fish and 
Wildlife Service (USFWS) and recent references, literature searches of 
search engines, peer review journals, and other technical reports, to 
provide a regional context for each species. The data were compiled 
from available sighting records, literature, satellite tracking, and 
stranding and by-catch data.
    A total of 24 cetacean species and subspecies and 4 pinniped 
species are known to occur in Washington State waters; however, several 
are seen only rarely. Seven of these marine mammal species are listed 
as Federally-endangered under the Endangered Species Act (ESA) occur or 
have the potential to occur in the proposed action area: Blue whale 
(Balaenoptera musculus), fin whale (B. physalus), Sei whale (B. 
borealis), humpback whale (Megaptera novaengliae), north Pacific right 
whale (Eubalaena japonica), sperm whale (Physeter macrocephalus), and 
the southern resident population of killer whales (Orcinus orca). The 
species, Steller sea lion (Eumetopias jubatus), is listed as threatened 
under the ESA. The Description of Marine Mammals in the Area of the 
Specified Activities section has not changed from what was in the 
proposed rule (74 FR 32264; July 7, 2009; pages 32268-32273). Lists of 
marine mammal species known to occur or potentially occur within the 
Keyport, DBRC, and QUTR sites are shown in Tables 4, 5, and 6, 
respectively.

A Brief Background on Sound

    An understanding of the basic properties of underwater sound is 
necessary to comprehend many of the concepts and analyses presented in 
this document. A detailed description of this topic was provided in the 
proposed rule (74 FR 32264; July 7, 2009; pages 32273-32274) and is not 
repeated herein.

Potential Impacts to Marine Mammal Species

    With respect to the MMPA, NMFS' effects assessment serves four 
primary purposes: (1) To prescribe the permissible methods of taking 
(i.e., Level B Harassment (behavioral harassment), Level A Harassment 
(injury), or mortality, including an identification of the number and 
types of take that could occur by Level A or B harassment or mortality) 
and to prescribe other means of effecting the least practicable adverse 
impact on such species or stock and its habitat (i.e., mitigation); (2) 
to determine whether the specified activity will have a negligible 
impact on the affected species or stocks of marine mammals (based on 
the likelihood that the activity will adversely affect the species or 
stock through effects on annual rates of recruitment or survival); (3) 
to determine whether the specified activity will have an unmitigable 
adverse impact on the availability of the species or stock(s) for 
subsistence uses; and (4) to prescribe requirements pertaining to 
monitoring and reporting.
    In the Potential Impacts to Marine Mammal Species section of the 
proposed rule, NMFS included a qualitative discussion of the different 
ways that sonar operations may potentially affect marine mammals. See 
74 FR 32264; July 7, 2009; pages 32274-42281. Marine mammals may 
experience direct physiological effects (such as threshold shift), 
acoustic masking, impaired communications, stress responses, and 
behavioral disturbance. The information contained in Potential Impacts 
to Marine Mammal Species from sonar operations section from the 
proposed rule has not changed.
    Additional analyses on potential impacts to marine mammals from 
vessel movement within the NAVSEA NUWC Keyport Range Complex Study Area 
are added below.

Vessel Movement

    There are limited data concerning marine mammal behavioral 
responses to vessel traffic and vessel noise, and a lack of consensus 
among scientists with respect to what these responses mean or whether 
they result in short-term or long-term adverse effects. In those cases 
where there is a busy shipping lane or where there is large amount of 
vessel traffic, marine mammals may experience acoustic masking 
(Hildebrand, 2005) if they are present in the area (e.g., killer whales 
in Puget Sound; Foote et al., 2004; Holt et al., 2008). In cases where 
vessels actively approach marine mammals (e.g., whale watching or 
dolphin watching boats), scientists have documented that animals 
exhibit altered behavior such as increased swimming speed, erratic 
movement, and active avoidance behavior (Bursk, 1983; Acevedo, 1991; 
Baker and MacGibbon, 1991; Trites and Bain, 2000; Williams et al., 
2002; Constantine et al., 2003), reduced blow interval (Ritcher et al., 
2003), disruption of normal social behaviors (Lusseau, 2003; 2006), and 
the shift of behavioral activities which may increase energetic costs 
(Constantine et al., 2003; 2004)). A detailed review of marine mammal 
reactions to ships and boats is available in Richardson et al. (1995). 
For each of the marine mammal's taxonomy groups, Richardson et al. 
(1995) provided the following assessment regarding marine mammal 
reactions to vessel traffic:
    Toothed whales: ``In summary, toothed whales sometimes show no 
avoidance reaction to vessels, or even approach them. However, 
avoidance can occur, especially in response to vessels of types used to 
chase or hunt the animals. This may cause temporary displacement, but 
we know of no clear evidence that toothed whales have abandoned 
significant parts of their range because of vessel traffic.''
    Baleen whales: ``When baleen whales receive low-level sounds from 
distant or stationary vessels, the sounds often seem to be ignored. 
Some whales approach the sources of these sounds. When vessels approach 
whales slowly and nonaggressively, whales often exhibit slow and 
inconspicuous avoidance maneuvers. In response to strong or rapidly 
changing vessel noise, baleen whales often interrupt their normal 
behavior and swim rapidly away. Avoidance is especially strong when a 
boat heads directly toward the whale.''
    Pinnipeds: ``In general, evidence about reactions of seals to 
vessels is meager. The limited data, plus the responses of seals to 
other noisy human activities, suggest that seals often show 
considerable tolerance of vessels. It is not known whether these 
animals are truly unaffected or are subject to stress. This uncertainty 
applies to many human activities and all marine mammals.'' In 
addressing walruses, Richardson et al. (1995) states, ``walrus 
reactions to ships include waking up, head-raises, and entering the 
water. Females with young seem more wary than adult males. Walruses in 
open water are less responsive than those on ice pans, usually showing 
little reaction unless the ship is about to run over them.''
    It is important to recognize that behavioral responses to stimuli 
are complex and influenced to varying degrees by a number of factors 
such as species, behavioral contexts, geographical regions, source 
characteristics (moving or stationary, speed, direction, etc.), prior 
experience of the animal, and physical status of the animal. For 
example, studies have shown that beluga whales reacted differently when 
exposed to vessel noise and traffic. In some cases, na[iuml]ve beluga 
whales exhibited rapid swimming from ice-breaking vessels up to 80 km 
away, and showed changes in surfacing, breathing, diving, and group 
composition in the Canadian high Arctic where vessel traffic is rare 
(Finley et al., 1990). In other cases, beluga whales were more tolerant 
of vessels, but differentially responsive by reducing their calling 
rates, to certain vessels and operating characteristics (especially 
older animals) in the St. Lawrence River where vessel traffic is common 
(Blane and Jaakson, 1994). In Bristol Bay, Alaska, beluga whales 
continued to feed when surrounded by fishing vessels and resisted 
dispersal even when purposefully harassed (Fish and Vania, 1971).
    In reviewing more than 25 years of whale observation data, Watkins 
(1986) concluded that whale reactions to vessel traffic were ``modified 
by their previous experience and current activity: Habituation often 
occurred rapidly,

[[Page 20263]]

attention to other stimuli or preoccupation with other activities 
sometimes overcame their interest or wariness of stimuli.'' Watkins 
noticed that over the years of exposure to ships in the Cape Cod area, 
minke whales (Balaenoptera acutorostrata) changed from frequent 
positive (such as approaching vessels) interest to generally 
uninterested reactions; finback whales (B. physalus) changed from 
mostly negative (such as avoidance) to uninterested reactions; right 
whales (Eubalaena glacialis) apparently continued the same variety of 
responses (negative, uninterested, and positive responses) with little 
change; and humpbacks (Megaptera novaeangliae) dramatically changed 
from mixed responses that were often negative to often strongly 
positive reactions. Watkins (1986) summarized that ``whales near shore, 
even in regions with low vessel traffic, generally have become less 
wary of boats and their noises, and they have appeared to be less 
easily disturbed than previously. In particular locations with intense 
shipping and repeated approaches by boats (such as the whale-watching 
areas of Stellwagen Bank), more and more whales had P [positive] 
reactions to familiar vessels, and they also occasionally approached 
other boats and yachts in the same ways.''
    In the case of the NAVSEA NUWC Keyport Range Complex Study Area, 
naval vessel traffic is expected to be much lower than in areas where 
there are large shipping lanes and large numbers of fishing vessels 
and/or recreational vessels. Nevertheless, the proposed action area is 
well traveled by a variety of commercial and recreational vessels, so 
marine mammals in the area are expected to be habituated to vessel 
noise.
    As described in the proposed rule, typical vessel movement 
occurring at the surface includes the deployment or towing of mine 
counter-measure equipment, retrieval of equipment, and clearing and 
monitoring for non-participating vessels. As shown in Table 1, the 
projected annual days of range use amount to a total of 306 days for 
all range sites (60 days for Keyport Range Site, 200 days for DBRC 
Site, 16 days for offshore QUTR Site, and 30 days for surf zone QUTR 
Site).
    Moreover, naval vessels transiting the study area or engaging in 
RDT&E activities will not actively or intentionally approach a marine 
mammal or change speed drastically. In addition, range craft would not 
be permitted to approach within 100 yards (91 m) of marine mammals, to 
the extent practicable considering human and vessel safety priorities. 
This includes marine mammals ``hauled-out'' on islands, rocks, and 
other areas such as buoys.

Mitigation

    In order to issue an incidental take authorization (ITA) under 
Section 101(a)(5)(A) of the MMPA, NMFS must prescribe regulations 
setting forth the ``permissible methods of taking pursuant to such 
activity, and other means of effecting the least practicable adverse 
impact on such species or stock and its habitat, paying particular 
attention to rookeries, mating grounds, and areas of similar 
significance.'' The NDAA amended the MMPA as it relates to military 
readiness activities and the incidental take authorization process such 
that ``least practicable adverse impact'' shall include consideration 
of personnel safety, practicality of implementation, and impact on the 
effectiveness of the ``military readiness activity.'' The NUWC Keyport 
Range Complex's RDT&E activities are considered military readiness 
activities.
    NMFS reviewed the Navy's proposed NUWC Keyport Range Complex's 
RDT&E activities and the proposed NUWC Keyport Range Complex's 
mitigation measures presented in the Navy's application to determine 
whether the activities and mitigation measures were capable of 
achieving the least practicable adverse effect on marine mammals.
    Any mitigation measure prescribed by NMFS should be known to 
accomplish, have a reasonable likelihood of accomplishing (based on 
current science), or contribute to the accomplishment of one or more of 
the general goals listed below:
    (1) Avoidance or minimization of injury or death of marine mammals 
wherever possible (goals (2), (3), and (4) may contribute to this 
goal).
    (2) A reduction in the numbers of marine mammals (total number or 
number at biologically important time or location) exposed to 
underwater detonations or other activities expected to result in the 
take of marine mammals (this goal may contribute to (1), above, or to 
reducing harassment takes only).
    (3) A reduction in the number of times (total number or number at 
biologically important time or location) individuals would be exposed 
to underwater detonations or other activities expected to result in the 
take of marine mammals (this goal may contribute to (1), above, or to 
reducing harassment takes only).
    (4) A reduction in the intensity of exposures (either total number 
or number at biologically important time or location) to underwater 
detonations or other activities expected to result in the take of 
marine mammals (this goal may contribute to (1), above, or to reducing 
the severity of harassment takes only).
    (5) A reduction in adverse effects to marine mammal habitat, paying 
special attention to the food base, activities that block or limit 
passage to or from biologically important areas, permanent destruction 
of habitat, or temporary destruction/disturbance of habitat during a 
biologically important time.
    (6) For monitoring directly related to mitigation--an increase in 
the probability of detecting marine mammals, thus allowing for more 
effective implementation of the mitigation (shut-down zone, etc.).
    NMFS reviewed the Navy's proposed mitigation measures, which 
included a careful balancing of the likely benefit of any particular 
measure to the marine mammals with the likely effect of that measure on 
personnel safety, practicality of implementation, and impact on the 
``military-readiness activity.''
    The Navy's proposed mitigation measures were described in detail in 
the proposed rule (74 FR 32264, pages 32293-32294). The Navy's measures 
address personnel training, marine observer responsibilities, operating 
procedures for RDT&E activities using sonar, and mitigation related to 
vessel traffic. The following additional requirements were added based 
on comments from the Marine Mammal Commission, Natural Resources 
Defense Council, and NMFS scientists:
    (i) If there is clear evidence that a marine mammal is injured or 
killed as a result of the proposed Navy RDT&E activities, the Naval 
activities shall be immediately suspended and the situation immediately 
reported by personnel involved in the activity to the Range Officer, 
who will follow Navy procedures for reporting the incident to NMFS 
through the Navy's chain-of-command.
    (j) For nighttime RDT&E activities of active acoustic transmissions 
in the Keyport Range proposed extension area, the Navy shall conduct 
passive acoustic monitoring within the Agate Pass and south of 
University Point in southern Port Orchard Reach. If Southern Resident 
killer whales are detected in the vicinity of the Keyport Range Site, 
the Range Office shall be notified immediately and the active acoustic 
sources must be shutdown if killer whales are confirmed to approach at 
1,000 yards from the source.
    In addition, in response to information provided by the Navy, the

[[Page 20264]]

requirement for general passive acoustic monitoring was modified to 
reflect the feasibility and practicability of PAM when used as a 
mitigation measure for the proposed RDT&E activities. The Navy 
indicated, and NMFS agreed, that the blanket requirement for PAM 
contained in the proposed rule will not be practicable due to 
limitation of assets at the Keyport Range Complex. Further, NMFS 
believes that the revised PAM would not change the results of the 
analysis on the effects of the proposed Keyport RDT&E activities on 
marine mammals. Therefore, the proposed mitigation measure concerning 
PAM has been modified as follows:
    (g) Passive acoustic monitoring for cetaceans will be implemented 
throughout the NUWC Keyport Range Complex during RDT&E testing 
activities involving active sonar transmissions and when passive 
acoustic monitoring capabilities are being operated during the testing 
activity.
    No other changes have been made to the mitigation measures 
described in the proposed rule.

Monitoring

    In order to issue an ITA for an activity, Section 101(a)(5)(A) of 
the MMPA states that NMFS must set forth ``requirements pertaining to 
the monitoring and reporting of such taking.'' The MMPA implementing 
regulations at 50 CFR 216.104 (a)(13) indicate that requests for LOAs 
must include the suggested means of accomplishing the necessary 
monitoring and reporting that will result in increased knowledge of the 
species and of the vel of taking or impacts on populations of marine 
mammals that are expected to be present.
    Monitoring measures prescribed by NMFS should accomplish one or 
more of the following general goals:
    (1) An increase in the probability of detecting marine mammals, 
both within the safety zone (thus allowing for more effective 
implementation of the mitigation) and in general to generate more data 
to contribute to the analyses mentioned below.
    (2) An increase in our understanding of how many marine mammals are 
likely to be exposed to levels of HFAS/MFAS (or explosives or other 
stimuli) that we associate with specific adverse effects, such as 
behavioral harassment, TTS, or PTS.
    (3) An increase in our understanding of how marine mammals respond 
to HFAS/MFAS (at specific received levels), explosives, or other 
stimuli expected to result in take and how anticipated adverse effects 
on individuals (in different ways and to varying degrees) may impact 
the population, species, or stock (specifically through effects on 
annual rates of recruitment or survival) through any of the following 
methods:
    <bullet> Behavioral observations in the presence of HFAS/MFAS 
compared to observations in the absence of sonar (need to be able to 
accurately predict received level and report bathymetric conditions, 
distance from source, and other pertinent information).
    <bullet> Physiological measurements in the presence of HFAS/MFAS 
compared to observations in the absence of sonar (need to be able to 
accurately predict received level and report bathymetric conditions, 
distance from source, and other pertinent information), and/or
    <bullet> Pre-planned and thorough investigation of stranding events 
that occur coincident to naval activities.
    <bullet> Distribution and/or abundance comparisons in times or 
areas with concentrated HFAS/MFAS versus times or areas without HFAS/
MFAS.
    (4) An increased knowledge of the affected species.
    (5) An increase in our understanding of the effectiveness of 
certain mitigation and monitoring measures.
    A detailed description of monitoring measures is provided in the 
proposed rule (74 FR 32264, pages 32294-32297). The monitoring 
procedures require the Navy to conduct visual surveys (including shore-
based and vessel surveys), passive acoustic monitoring, and marine 
mammal observers on Navy vessels.

Monitoring Workshop

    During the public comment period on past proposed rules for Navy 
actions (such as the Hawaii Range Complex (HRC), and Southern 
California Range Complex (SOCAL) proposed rules), NMFS received a 
recommendation that a workshop or panel be convened to solicit input on 
the monitoring plan from researchers, experts, and other interested 
parties. The NAVSEA NUWC Keyport Range Complex RDT&E proposed rule 
included an adaptive management component and both NMFS and the Navy 
believe that a workshop would provide a means for Navy and NMFS to 
consider input from participants in determining whether (and if so, 
how) to modify monitoring techniques to more effectively accomplish the 
goals of monitoring set forth earlier in the document. NMFS and the 
Navy believe that this workshop is valuable in relation to all of the 
Range Complexes and major training exercise rules and LOAs that NMFS is 
working on with the Navy at this time, and consequently this single 
Monitoring Workshop will be included as a component of all of the rules 
and LOAs that NMFS will be processing for the Navy in the next year or 
so.
    The Navy, with guidance and support from NMFS, will convene a 
Monitoring Workshop, including marine mammal and acoustic experts as 
well as other interested parties, in 2011. The Monitoring Workshop 
participants will review the monitoring results from the previous two 
years of monitoring pursuant to the NAVSEA NUWC Keyport Range Complex 
RDT&E rule as well as monitoring results from other Navy rules and LOAs 
(e.g., AFAST, SOCAL, HRC, and other rules). The Monitoring Workshop 
participants would provide their individual recommendations to the Navy 
and NMFS on the monitoring plan(s) after also considering the current 
science (including Navy research and development) and working within 
the framework of available resources and feasibility of implementation. 
NMFS and the Navy would then analyze the input from the Monitoring 
Workshop participants and determine the best way forward from a 
national perspective. Subsequent to the Monitoring Workshop, 
modifications would be applied to monitoring plans as appropriate.

Integrated Comprehensive Monitoring Program

    In addition to the site-specific Monitoring Plan for the NAVSEA 
NUWC Keyport Range Complex Study Area, the Navy will complete the 
Integrated Comprehensive Monitoring Program (ICMP) Plan by the end of 
2009. The ICMP is currently in development by the Navy, with the Chief 
of Naval Operations Environmental Readiness Division (CNO-N45) having 
the lead. The program does not duplicate the monitoring plans for 
individual areas (e.g., AFAST, HRC, SOCAL); instead it is intended to 
provide the overarching coordination that will support compilation of 
data from both range-specific monitoring plans as well as Navy funded 
research and development (R&D) studies. The ICMP will coordinate the 
monitoring program's progress towards meeting its goals and developing 
a data management plan. A program review board is also being considered 
to provide additional guidance. The ICMP will be evaluated annually to 
provide a matrix for progress and goals for the following year, and 
will make recommendations on adaptive management for refinement and 
analysis of the monitoring methods.

[[Page 20265]]

    The primary objectives of the ICMP are to:
    <bullet> Monitor and assess the effects of Navy activities on 
protected species;
    <bullet> Ensure that data collected at multiple locations is 
collected in a manner that allows comparison between and among 
different geographic locations;
    <bullet> Assess the efficacy and practicality of the monitoring and 
mitigation techniques;
    <bullet> Add to the overall knowledge-base of marine species and 
the effects of Navy activities on marine species.
    The ICMP will be used both as: (1) A planning tool to focus Navy 
monitoring priorities (pursuant to ESA/MMPA requirements) across Navy 
Range Complexes and Exercises; and (2) an adaptive management tool, 
through the consolidation and analysis of the Navy's monitoring and 
watchstander/marine observer data, as well as new information from 
other Navy programs (e.g., R&D), and other appropriate newly published 
information.
    In combination with the 2011 Monitoring Workshop and the adaptive 
management component of the NAVSEA NUWC Keyport Range Complex RDT&E 
rule and the other planned Navy rules (e.g., Virginia Capes Range 
Complex, Jacksonville Range Complex, Cherry Point Range Complex, etc.), 
the ICMP could potentially provide a framework for restructuring the 
monitoring plans and allocating monitoring effort based on the value of 
particular specific monitoring proposals (in terms of the degree to 
which results would likely contribute to stated monitoring goals, as 
well as the likely technical success of the monitoring based on a 
review of past monitoring results) that have been developed through the 
ICMP framework, instead of allocating based on maintaining an equal (or 
commensurate to effects) distribution of monitoring effort across range 
complexes. For example, if careful prioritization and planning through 
the ICMP (which would include a review of both past monitoring results 
and current scientific developments) were to show that a large, intense 
monitoring effort in Hawaii would likely provide extensive, robust and 
much-needed data that could be used to understand the effects of sonar 
throughout different geographical areas, it may be appropriate to have 
other range complexes dedicate money, resources, or staff to the 
specific monitoring proposal identified as ``high priority'' by the 
Navy and NMFS, in lieu of focusing on smaller, lower priority projects 
divided throughout their home range complexes.
    The ICMP will identify:
    <bullet> A means by which NMFS and the Navy would jointly consider 
prior years' monitoring results and advancing science to determine if 
modifications are needed in mitigation or monitoring measures to better 
effect the goals laid out in the Mitigation and Monitoring sections of 
the NAVSEA NUWC Keyport Range Complex RDT&E rule.
    <bullet> Guidelines for prioritizing monitoring projects.
    If, as a result of the workshop and similar to the example 
described in the paragraph above, the Navy and NMFS decide it is 
appropriate to restructure the monitoring plans for multiple ranges 
such that they are no longer evenly allocated (by rule), but rather 
focused on priority monitoring projects that are not necessarily tied 
to the geographic area addressed in the rule, the ICMP will be modified 
to include a very clear and unclassified record-keeping system that 
will allow NMFS and the public to see how each range complex/project is 
contributing to all of the ongoing monitoring programs (resources, 
effort, money, etc.).

Adaptive Management

    The final regulations governing the take of marine mammals 
incidental to Navy's NAVSEA NUWC Keyport Range Complex RDT&E activities 
contain an adaptive management component. The use of adaptive 
management will give NMFS the ability to consider new data from 
different sources to determine (in coordination with the Navy) on an 
annual basis if mitigation or monitoring measures should be modified or 
added (or deleted) if new data suggests that such modifications are 
appropriate (or are not appropriate) for subsequent annual LOAs.
    The following are some of the possible sources of applicable data:
    <bullet> Results from the Navy's monitoring from the previous year 
(either from NAVSEA NUWC Keyport Range Complex Study Area or other 
locations)
    <bullet> Findings of the Workshop that the Navy will convene in 
2011 to analyze monitoring results to date, review current science, and 
recommend modifications, as appropriate to the monitoring protocols to 
increase monitoring effectiveness
    <bullet> Compiled results of Navy-funded research and development 
(R&D) studies (presented pursuant to the ICMP, which is discussed 
elsewhere in this document)
    <bullet> Results from specific stranding investigations (either 
from NAVSEA NUWC Keyport Range Complex Study Area or other locations)
    <bullet> Results from general marine mammal and sound research 
(funded by the Navy or otherwise)
    <bullet> Any information which reveals that marine mammals may have 
been taken in a manner, extent or number not authorized by these 
regulations or subsequent Letters of Authorization
    Mitigation measures could be modified or added (or deleted) if new 
data suggest that such modifications would have (or do not have) a 
reasonable likelihood of accomplishing the goals of mitigation laid out 
in this final rule and if the measures are practicable. NMFS would also 
coordinate with the Navy to modify or add to (or delete) the existing 
monitoring requirements if the new data suggest that the addition of 
(or deletion of) a particular measure would more effectively accomplish 
the goals of monitoring laid out in this final rule. The reporting 
requirements associated with this rule are designed to provide NMFS 
with monitoring data from the previous year to allow NMFS to consider 
the data and issue annual LOAs. NMFS and the Navy will meet annually, 
prior to LOA issuance, to discuss the monitoring reports, Navy R&D 
developments, current science and whether mitigation or monitoring 
modifications are appropriate.

Reporting

    In order to issue an ITA for an activity, Section 101(a)(5)(A) of 
the MMPA states that NMFS must set forth ``requirements pertaining to 
the monitoring and reporting of such taking.'' Effective reporting is 
critical to ensure compliance with the terms and conditions of a LOA, 
and to provide NMFS and the Navy with data of the highest quality based 
on the required monitoring. As NMFS noted in its proposed rule, 
additional detail has been added to the reporting requirements since 
they were outlined in the proposed rule. The updated reporting 
requirements are all included below. A subset of the information 
provided in the monitoring reports may be classified and not releasable 
to the public.

General Notification of Injured or Dead Marine Mammals

    Navy personnel will ensure that NMFS (regional stranding 
coordinator) is notified immediately (or as soon as operational 
security allows) if an injured or dead marine mammal is found during or 
shortly after, and in the vicinity of, any Navy RDT&E activities. The 
Navy will provide NMFS with species or description of the animal(s), 
the condition of the animal(s) (including

[[Page 20266]]

carcass condition if the animal is dead), location, time of first 
discovery, observed behaviors (if alive), and photo or video (if 
available).

Annual Report

    The NAVSEA NUWC Keyport Range Complex shall submit a report 
annually on October 1 describing the RDT&E activities conducted and 
implementation and results of the NAVSEA NUWC Keyport Range Complex 
Monitoring Plan (through June 1 of the same year) and RDT&E activities. 
The report will, at a minimum, include the following information:
    (1) RDT&E Information:
    <bullet> Date and time test began and ended
    <bullet> Location
    <bullet> Number and types of active sources used in the test
    <bullet> Number and types of vessels, aircraft, etc., participated 
in the test
    <bullet> Total hours of observation effort (including observation 
time when sonar was not operating)
    <bullet> Total hours of all active sonar source operation
    <bullet> Total hours of each active sonar source
    <bullet> Wave height (high, low, and average during the test)
    (2) Individual Marine Mammal Sighting Info
    <bullet> Location of sighting
    <bullet> Species
    <bullet> Number of individuals
    <bullet> Calves observed (y/n)
    <bullet> Initial detection sensor
    <bullet> Indication of specific type of platform observation made 
from
    <bullet> Length of time observers maintained visual contact with 
marine mammal(s)
    <bullet> Wave height (in feet)
    <bullet> Visibility
    <bullet> Sonar source in use (y/n)
    <bullet> Indication of whether animal is <200 yd, 200-500 yd, 500-
1,000 yd, 1,000-2,000 yd, or >2,000 yd from sonar source above
    <bullet> Mitigation implementation--Whether operation of sonar 
sensor was delayed, or sonar was powered or shut down, and how long the 
delay was
    <bullet> Observed behavior--Marine observers shall report, in plain 
language and without trying to categorize in any way, the observed 
behavior of the animals (such as animal closing to bow ride, 
paralleling course/speed, floating on surface and not swimming, etc.)
    <bullet> An evaluation of the effectiveness of mitigation measures 
designed to avoid exposing marine mammals to mid-frequency sonar. This 
evaluation shall identify the specific observations that support any 
conclusions the Navy reaches about the effectiveness of the mitigation.

NAVSEA NUWC Keyport Range Complex 5-yr Comprehensive Report

    The Navy will submit to NMFS a draft report that analyzes and 
summarizes all of the multi-year marine mammal information gathered 
during HFAS/MFAS activities for which annual reports are required as 
described above. This report will be submitted at the end of the fourth 
year of the rule (December 2014), covering activities that have 
occurred through July 1, 2014. The Navy will respond to NMFS comments 
on the draft comprehensive report if submitted within 3 months of 
receipt. The report will be considered final after the Navy has 
addressed NMFS' comments, or three months after the submittal of the 
draft if NMFS does not comment by then.

Comments and Responses

    On July 7, 2009, NMFS published a proposed rule (74 FR 32264) in 
response to the Navy's request to take marine mammals incidental to 
conducting RDT&E activities in the NAVSEA NUWC Keyport Range Complex 
Study Area and requested comments, information and suggestions 
concerning the request. During the 30-day public comment period, NMFS 
received comments from the Marine Mammal Commission (Commission), the 
Natural Resources Defense Council (NRDC), Friends of the Earth, and two 
private citizens. The comments are addressed below.

MMPA Concerns

    Comment 1: Citing that most North American marine mammal biologists 
are in the field and that the general public is engaged in recreational 
activities during the period when the proposed rule was published for 
public comments, the Friends of the Earth requests NMFS to extend the 
comment period for a minimum of 30 days for the proposed rule.
    Response: There is no prescribed minimum timeframe for public 
comment on proposed rules in the Administrative Procedure Act (APA) or 
section 101(a)(5)(A) of MMPA. NMFS routinely strives to ensure that the 
public is afforded at least a 30-day public comment period on all MMPA 
rules and believes that such a duration is reasonable for this 
particular rule making.
    Whenever NMFS develops proposed regulations under the MMPA, the 
agency is required to first publish a notice of receipt of a request 
for the implementation of regulations and LOAs governing the incidental 
taking. This process typically affords the public up to 30 days to 
comment on a requester's application and provide NMFS with information 
and suggestions that will be considered in developing MMPA regulations. 
See 50 CFR 216.104. On July 3, 2008, NMFS published its ``Notice; 
receipt of application for a Letter of Authorization (LOA); request for 
comments and information'' for the Navy's NAVSEA NUWC Keyport Range 
Complex and solicited input for 30 days (See 73 FR 38183).
    The public was also afforded 30 days to comment on the Keyport 
Range Complex proposed rule. For the proposed MMPA rulemaking for the 
Navy training and RDT&E activities, thirty days was appropriate in this 
instance because of: (1) The tight deadline of the scheduled RDT&E or 
training activities identified in the Navy's schedule; and (2) the fact 
that NMFS anticipated only low impacts to marine mammals with the 
implementation of mitigation and monitoring measures. Therefore, NMFS 
does not believe an additional 30-day comment period is warranted.
    Comment 2: The Commission recommends that NMFS: (1) Work with the 
Navy to ensure that the final rule and any LOA issued under that rule 
provide authorization for the taking of all marine mammal species that 
could occur in the study area (including those listed under the 
Endangered Species Act) and that may be exposed to Level A or Level B 
harassment as a result of the proposed activities; and (2) either 
reconsider its decision to exclude endangered and threatened species 
from the authorization or provide a well-reasoned, science-based 
explanation for its apparent belief that the proposed mitigation 
measures will be much more effective for listed species than for 
unlisted species.
    Response: First, NMFS worked with the Navy to ensure that the rule 
provides authorization for animals that are likely to be taken in the 
area, but NMFS does not agree with the Commission's recommendation that 
NMFS' final rule and LOAs should authorize takes of all marine mammal 
species that are known to occur in the Keyport Range Complex Study 
Area, regardless of how infrequently they occur. Second, to clarify, 
NMFS does not believe that the proposed mitigation measures will be 
much more effective for listed species than for unlisted species, 
rather, all of the listed species fell into a larger group of marine 
mammals that occur rarely and infrequently in Keyport and are unlikely 
to be exposed to the Navy sound sources

[[Page 20267]]

at all and, therefore, unlikely to be taken.
    As described in the proposed rule (74 FR 32264; July 7, 2009), the 
annual estimated number of exposures from acoustic sources are given 
for each species, based on the abundance, distribution, and density of 
these species. NMFS is not authorizing the take of every marine mammal 
species that could potentially occur in the Keyport Range Complex Study 
Area, since many of these species (all ESA-listed species and some non-
listed) occur rarely (e.g., blue whale, fin whale, sei whale, North 
Pacific right whale, minke whale, killer whale, and striped dolphin) or 
occur infrequently (e.g., humpback whale, Baird's beaked whale, Hubb's 
beaked whale, Stejneger's beaked whale, Risso's dolphin, short-beaked 
common dolphin, sperm whale, dwarf sperm whale, pygmy sperm whale, 
northern elephant seal, and Steller sea lion). In fact, none of the 
ESA-listed species are commonly found in the Keyport Range Complex 
Study Area, and NMFS' Biological Opinion for Keyport and NWTRC also 
indicates that these species will not be taken by the Keyport 
activities.
    The estimates of 11,283 takes of harbor porpoises, 44 takes of 
northern fur seal, 114 takes of California sea lions, and 5,569 takes 
of harbor seals by Level B harassment as a result of the proposed 
Keyport Range Complex RDT&E activities are based on scientific modeling 
for acoustic sources using the risk function methodology, coupled with 
the analysis of the abundance, distribution, and density of marine 
mammal species in the action area.
    Comment 3: The Commission requests NMFS describe the ``specified 
events'' that would involve or require special surveys at the Dabob Bay 
Range site (74 FR 32264; July 7, 2009; page 32295).
    Response: According to the Navy, a ``specified event'' is a test or 
run plan well suited for monitoring because certain operational and 
environmental parameters are in place (e.g., high level of activity, 
bottom mounted hydrophone in place, controlled environment, etc.; see 
74 FR 32264; July 7, 2009; page 32295). As an RDT&E facility, it is 
important to maintain an open perspective of what kind of mid and high 
frequency events may be best for a special survey. Examples of the 
types of scenarios that would be considered for monitoring scenarios 
are those utilizing the high frequency systems that were modeled such 
as sources S6, S7, or S8 described in the proposed rule (74 FR 32264; 
July 7, 2009; page 32288). These may include a test unit and a launch 
and recovery craft and associated tracking sonar. For monitoring an 
activity with a mid frequency source, a range target operating at the 
lower end of its frequency range (5-100 kHz) at source level of 238 
microPa @ 1 m or a countermeasure under test with an output frequency 
between 1 and 10 kHz may be the appropriate type of test to use for 
monitoring.

Mitigation

    Comment 4: The Commission requests NMFS require the Navy to suspend 
an activity if a marine mammal is killed or seriously injured and the 
death or injury could be associated with the Navy's activities, and 
resumption of the activity should be contingent upon a review by NMFS 
of the circumstances of the death or injury and the Navy's plans for 
avoiding additional mortalities. If, upon review, those plans are 
deemed inadequate, then the Navy should be required to halt its 
operations until it has obtained the necessary authorization.
    Response: Without detailed examination by an expert, it is usually 
not feasible to determine the cause of injury or mortality in the 
field. Therefore, NMFS has required in its final rule that if there is 
clear evidence that a marine mammal is injured or killed as a result of 
the proposed Navy RDT&E activities, the Naval activities shall be 
immediately suspended and the situation immediately reported by 
personnel involved in the activity to the Range Officer, who will 
follow Navy procedures for reporting the incident to NMFS through the 
Navy's chain-of-command.
    For any other sighting of injured or dead marine mammals in the 
vicinity of any Navy RDT&E activities utilizing underwater active 
acoustic sources for which the cause of injury or mortality cannot be 
immediately determined, the Navy personnel will ensure that NMFS 
(regional stranding coordinator) is notified immediately (or as soon as 
operational security allows). The Navy will provide NMFS with species 
or description of the animal(s), the condition of the animal(s) 
(including carcass condition if the animal is dead), location, time of 
first discovery, observed behaviors (if alive), and photo or video (if 
available).
    If NMFS determines that further investigation is appropriate, once 
investigations are completed and determinations made, NMFS would use 
the resulting information, if appropriate, to help reduce the 
likelihood that a similar event would happen in the future and to move 
forward with necessary steps to ensure environmental compliance for the 
Navy under the MMPA.
    Comment 5: Stating that waters out to at least the 100-meter 
isobath represent vital habitat for a discrete population of harbor 
porpoises, the Oregon/Washington Coast stock, that the species has 
acute sensitivity to acoustic sources, and that the offshore population 
of approximately 37,745 would be exposed over 11,000 times, 
representing nearly 99 percent of all take authorized for QUTR under 
the proposed rule, the NRDC recommends establishing a protection area 
within waters landward of the 100-meter isobath. In addition, the NRDC 
recommends a buffer zone reflecting the sensitivity of the species 
should be applied beyond the 100-meter isobath, optimally ensuring that 
exposure levels within the 100-meter isobath do not exceed 120 dB. The 
NRDC recommends that NMFS ask the Navy to prepare a nominal propagation 
analysis for the coast to determine what stand-off distances are 
necessary to reduce exposure levels below this threshold.
    Response: In order to determine the appropriate mitigation measures 
for a particular activity, NMFS must balance the benefit of the measure 
to the species, the likely effectiveness of a given measure, and the 
practicability of the measure for applicant implementation.
    First, the estimated incidental takes of harbor porpoises are 
expected to be non-injurious, short-term Level B harassment. It is 
reasonable to expect high numbers of takes due to multiple takes of one 
individual in a year (not every estimated take represents a different 
individual). Given the nature of the activity, it is more likely that a 
percentage of the population (as opposed to the entire population) 
would be taken with each event, and that over time multiple repetitions 
of exposure to these short-term exercises would occur.
    Regarding NRDC's recommendation, a buffer zone applied beyond the 
100-meter isobaths is not practicable for this activity and would 
seriously affect the Navy's proposed RDT&E activities. While it is true 
that most Oregon/Washington Coast stock harbor porpoises occur in 
waters shallower than 100-m, excluding these regions would not be 
practicable, as it would mean that large regions of the Keyport Range 
Complex Study Area would be off limits for the proposed RDT&E 
activities. For example, the 100-m isobaths in the W237A Area of the 
QUTR Range Site extend off shore for more than 7 miles. With such large 
areas and all of the area of that specific depth range off limits to 
the proposed RDT&E activities, the Navy would not be able to

[[Page 20268]]

fulfill its mission activities. It is also not practicable to recommend 
a ``do not exceed 120 dB'' level within the 100-m isobath, as some of 
the active sources have received levels reaching 120 dB at ranges over 
66 km (Table 7).
    The majority of the harbor seals take numbers include exposures 
close to this 120-dB threshold level (rather than at a higher exposure 
level), due to the large Level B harassment isopleths. The effects of 
exposures to this lower level are expected to be comparatively less 
severe. Also, none of these exposures are expected to affect the stock 
through effects on annual rates of survival and reproduction.

    As stated in this document, exposures to marine mammals are 
expected to be limited to Level B harassment, and the seemingly large 
takes of harbor porpoise do not represent the individual animals that 
would be taken, instead, some individuals may be taken multiple times. 
Among these multiple takes, only 1 animal is expected to be exposed 
once to received levels that could cause minor TTS. Further, the NRDC's 
proposed mitigation of limiting the RDT&E activities to water deeper 
than 100-m isobaths would compromise the Navy's ability to accomplish 
their mission with limited added benefit to the species. Mitigation and 
monitoring measures, such as establishing and monitoring exclusion 
zones and shutdown measures, are expected to achieve the least 
practicable adverse impacts to marine mammals in the vicinity of the 
proposed project area.
    Separately, NOAA has committed to convene a workshop of marine 
mammal experts in 2010/2011 to identify cetacean hotspots (areas of 
specifically important use or high density) using both field data and 
habitat modeling, as appropriate. The workshop results, in turn, could 
potentially support the need to designate protected areas in which Navy 
activities could potentially be limited, depending on NMFS' analysis of 
the benefit to the species of limiting activities in the area, the 
likely effectiveness of the measure, and the practicability of 
implementation. The adaptive management provisions in the Keyport rule 
would allow for the application of these protected areas, as 
appropriate.
    Comment 6: The NRDC requests NMFS provide additional protection 
from the use of mid- and high-frequency acoustic sources within the 
Olympic Coast National Marine Sanctuary (NMS). Specifically, for those 
activities that do not require QUTR's instrumentation, NMFS should 
include measures to prohibit such activities from taking place in 
sanctuary waters. If this proves impracticable, the NRDC urges NMFS to 
substantially limit the number of RDT&E activities taking place by 
requiring prior approval from Pacific Fleet Command or other means to 
minimize sonar use in the area.
    Response: NMFS has been working with the Navy throughout the 
rulemaking process to develop a series of strict mitigation and 
monitoring measures regarding the use of active acoustic sources in the 
Keyport Range Complex, which overlaps with the Olympic Coast NMS. These 
measures include the use of trained Navy marine observers who will 
conduct marine mammal monitoring to avoid collisions with marine 
mammals and the use of exclusion zones that avoid exposing marine 
mammals to levels of sound likely to result in temporary hearing loss, 
injury or death of marine mammals. However, prohibition of RDT&E 
activities and/or substantially limiting the number of RDT&E activities 
within the Olympic Coast NMS would compromise the Navy's mission and is 
impracticable for the proposed activities. The area and the number of 
the RDT&E events that were proposed to be carried out were carefully 
planned to have the least practicable adverse impacts to marine mammals 
while still meeting the Navy's RDT&E mission activity. In addition, the 
level and number of RDT&E events authorized are the maximum activities 
allowed within the five-year rule period; the actual number of events 
could be fewer than proposed.
    Comment 7: The NRDC recommends that NMFS establish a seasonal 
protection area in certain canyons and banks on QUTR that represent 
important foraging habitat particularly for humpback whales. Citing 
Calambokidis et al. (2004), the NRDC states that humpback whales occur 
mostly in the northern part of the area, in a region informally known 
as the ``Prairie.'' The NRDC further states that sonar impacts on 
beaked whales are also a concern in QUTR because these species have a 
general preference for waters of the lower continental slope. The NRDC 
requests NMFS to advocate avoidance, or a reduction of RDT&E 
activities, within areas between 500 and 2,000 meters depth with 
unusual bottom topography (such as canyons).
    Response: There are no canyons or banks in the currently 
instrumented test range within the QUTR range site and its associated 
depth is limited to 91 meters. The proposed extension of the QUTR range 
site would expand the range boundaries to the full extent of range area 
W-237A, which does include canyons and banks and the varied topography. 
W-237A was determined to be a vital asset by the Navy to perform its 
RDT&E mission, and the proposed extension of the existing QUTR range 
site into the entire W-237A area is critical to fulfill the Navy's 
RDT&E mission activity. In addition, seasonal variability of oceanic 
conditions was also considered an important component of the Navy's 
RDT&E mission, and activities must be able to occur year round. 
Therefore, a restriction on seasonal use of the canyon and banks and 
making the areas between 500 and 2,000 meters off-limits to the 
proposed Keyport RDT&E operations would severely limit the Navy's 
mission activities, and will not be a practicable measure.
    Although NMFS recognizes that the extended QUTR range site would 
include known feeding habitat for certain species of marine mammals 
including humpback whales, and the undersea canyon and banks of the 
type that are known to be used by beaked whales for feeding, the 
proposed RDT&E activities to be conducted within the extended QUTR 
range site would only take 16 days per year at its offshore area, with 
total operation time for all active acoustic sources adding up to 
approximately 507 hours, and the range tests would be comprised of low 
intensity mid- and high-frequency active acoustic sources (see 
Description of Specific Activities section above). In addition, 
humpback whales and beaked whales are rare within the proposed Keyport 
Range Complex. Scientific modeling on take calculations shows that the 
take of these species, even by Level B behavioral harassment, is very 
unlikely.
    Lastly, as mentioned above, NMFS has been working with the Navy 
throughout the rulemaking process to develop a series of mitigation and 
monitoring measures so that adverse impact to marine mammals and their

[[Page 20269]]

habitat will be the least that is practicable. These measures include 
the use of trained Navy marine observers who will conduct marine mammal 
monitoring to avoid collisions with marine mammals and the use of 
exclusion zones that avoid exposing marine mammals to levels of sound 
likely to result in injury or death of marine mammals. The 
determination of appropriate mitigation measures includes consideration 
of benefit of the proposed measure to marine mammals, the likely 
effectiveness of the measure, and the practicability of the measure for 
applicant implementation. NMFS believes that the measures required of 
the Navy will result in the least practicable adverse impact.
    Comment 8: The NRDC requests NMFS bar the use of mid- and high-
frequency acoustic sources in those portions of the Keyport Range that 
extend into designated critical habitat for Southern Resident killer 
whales because these waters in Puget Sound are one of the most 
important habitats for the Southern Resident community of killer whales 
(and their near-exclusive habitat in summer/autumn months).
    Response: The occurrence of Southern Resident killer whales (SRKW) 
in waters in the vicinity of the Keyport Range Site is rare (NMFS, 
2006). The Navy conducted a density estimate of killer whales in inland 
waters of the Keyport Range Complex and concluded that density is zero 
for the Keyport Range Site (Navy, 2008). No take of SRKWs is expected 
or authorized. Therefore, NMFS does not agree with NRDC's 
recommendation.
    The Keyport Range Complex has been at this site since 1914, and the 
existing Keyport Range Site was excluded from NMFS' 2006 critical 
habitat designation after a balancing of conservation benefits against 
national security considerations. The proposed Keyport Range Site 
extension would expand the existing range into the Southern Resident 
killer whale critical habitat. The extension would increase the area of 
the Keyport Range Site from 1.5 nm\2\ to 1.7 nm\2\ (5.1 km\2\ to 5.9 
km\2\). The area in critical habitat is therefore approximately 0.2 
nm\2\ (0.8 km\2\).
    The Navy is required to shut down any active acoustic sources when 
any whale or dolphin is detected within 1,000 yards of the source. 
Modeling of three of the most powerful sources at the Keyport Range 
Site indicates that the received level at 1,000 yards drops down to 145 
dB re 1 microPa, which is the level at which the risk function 
indicates a very small percentage of exposed animals would be harassed. 
Therefore, NMFS does not believe that the proposed RDT&E activities in 
the vicinity of SRKW critical habitat would result in the take this 
species if the shut-down mitigation measure is implemented.
    Killer whales are mid-sized cetacean species with distinctive large 
dorsal fins and can be detected from a large distance, which allows 
mitigation and monitoring measures to be effectively carried out. 
However, to account for nighttime activities, NMFS has included an 
additional measure that will provide further assurance that no SRKW 
would be taken in the vicinity of the Keyport Range site. This 
additional measure requires the Navy to place a passive acoustic 
monitoring system at the northern and southern approaches to Port 
Orchard Reach and to conduct passive acoustic monitoring within the 
Agate Pass and south of University Point in southern Port Orchard Reach 
for nighttime RDT&E activities conducted in the Keyport Range Site 
Extension. If Southern Resident killer whales are detected in the 
vicinity of the Keyport Range Site, the Range Office shall be notified 
immediately and, in accordance with the required mitigation for all 
cetaceans, the active acoustic sources must be shutdown if killer 
whales are confirmed to approach at 1,000 yards from the source. NMFS 
considers passive acoustic monitoring for SRKW to be an effective way 
to supplement detection of this population in low light conditions, 
given that they are known to be more vocal compared to transient killer 
whales (Deecke et al., 2005).
    Comment 9: Citing that the exclusion zone for cetaceans is 1,000 
yards and the exclusion zone for pinnipeds is 100 yards, the NRDC 
states that NMFS fails to explain why pinnipeds should be afforded less 
protection than cetaceans, especially as it notes that harbor seals 
will experience TTS onset at 183 dB, while cetaceans generally will 
experience TTS onset at 195 dB. The NRDC requests NMFS require a 1,000 
yard exclusion zone for all marine mammals.
    Response: Pinnipeds are abundant in the Keyport and Dabob current 
and proposed extensions. Given the limited operating area, close shore 
proximity and abundance of animals residing at the ranges, a greater 
standoff for pinnipeds would result in a large majority of activities 
interrupted, postponed or cancelled. As a result, the Keyport Range 
Complex would not meet its mission requirements, making such a measure 
impracticable. On the other hand, cetaceans are not as numerous as 
pinnipeds, and they are more easily detected at larger distances, 
allowing for the practicable implementation of a larger standoff 
distance.
    The range to 183 dB re 1 microPa\2\ (onset of TTS for harbor seal) 
for the mid frequency active acoustic source S5, which has a source 
level at 233 dB re 1 microPa @ 1 m (the highest of all active acoustic 
sources being used at Keyport Range Complex) is approximately 464 m. 
The total operation time for range target, which is under the S5 source 
type designation, is 9 hours per year for the entire Keyport Range 
Complex. All other active acoustic sources have lower source levels and 
thus the ranges to 183 dB 1 microPa\2\ are expected to be much shorter. 
Although it is estimated that more than 2,000 harbor seals would incur 
Level B harassment which could cause TTS, the TTS is expected to be 
short-term in duration and of a low level (due to the modeled received 
levels, see Keyport Range Complex FEIS/OEIS, Navy, 2009). Even if TTS 
occurs in harbor seals, it is expected in the much higher frequency in 
their communication range. Additionally, no takes by Level A harassment 
are anticipated, based on the modeling results.
    Sonar operations within the Keyport Range Complex have been ongoing 
for over 50 years and evidence shows that the pinniped populations 
remain abundant.

Monitoring

    Comment 10: The NRDC request that NMFS require long-term monitoring 
of local populations on all ranges to see if any populations reflect 
habitat displacement or exhibit other negative impacts.
    Response: NMFS agrees with the NRDC's suggestion. The Keyport Range 
Complex maintains a database of marine mammal sighting since 2003. NMFS 
is working and will continue to work with the Navy to develop and 
implement monitoring plans to help better understand the impacts of all 
Naval RDT&E and training activities that have the potential to 
adversely affect marine mammal species and their habitat. For the 
proposed Keyport Range Complex RDT&E activities, various monitoring 
measures will be implemented and are described in the Monitoring 
section of this document.
    Comment 11: The Commission requests that NMFS require the Navy to 
develop and implement a detailed plan to verify the performance of the 
visual monitoring, passive acoustic monitoring, and other monitoring 
and mitigation measures being proposed to enable the Navy, NMFS, and 
other

[[Page 20270]]

interested parties to evaluate their effectiveness.
    Response: NMFS has worked with the Navy throughout the rulemaking 
process to develop a series of mitigation, monitoring, and reporting 
protocols that will effect the least practicable adverse impact and 
increase our understanding of the impact of these activities on marine 
mammals. These monitoring and reporting measures include, but are not 
limited to: (1) The use of trained Navy marine observers who will 
conduct marine mammal monitoring to avoid collisions with marine 
mammals; (2) the use of exclusion zones that avoid exposing marine 
mammals to levels of sound likely to result in injury or death of 
marine mammals; (3) the use of MMOs/Navy marine observers to conduct 
vessel and shore-based surveys; and (4) annual monitoring reports and 
comprehensive reports to provide insights regarding impacts to marine 
mammals.
    NMFS will evaluate the effectiveness of these measures through 
review and analyses of the Navy's annual monitoring reports, the annual 
adaptive management meetings required by the final 5-year rule, as well 
as a required Monitoring workshop that will be convened in 2011 to 
solicit detailed input from experts regarding the effectiveness of the 
Navy's monitoring. NMFS will, through this established adaptive 
management process, work with the Navy to determine whether additional 
mitigation and monitoring measures are necessary. In addition, with the 
ICMP, which is a comprehensive monitoring planning and prioritization 
tool, and the planned Monitoring Workshop in 2011, NMFS will work with 
the Navy and other interested parties to further improve its monitoring 
and mitigation plans for its future activities.

Miscellaneous Issues

    Comment 12: Two individuals expressed general opposition to Navy 
testing and bombing activities and NMFS' issuance of an MMPA 
authorization because of the danger of killing marine life.
    Response: NMFS appreciates the commenters' concern for the marine 
mammals that live in the area of the proposed activities. However, the 
proposed Keyport Range Complex activities do not include bombing or any 
explosive detonations. The proposed activities, as described in detail 
in the Proposed Rule (74 FR 32264; July 7, 2009), include the use of 
active acoustic sources to conduct the Navy's RDT&E activities. In 
addition, the MMPA allows individuals to take marine mammals incidental 
to specified activities if NMFS can make the necessary findings 
required by law (i.e., negligible impact, unmitigable adverse impact on 
subsistence users, etc.). As explained throughout this rulemaking, NMFS 
has made the necessary findings under 16 U.S.C. 1371(a)(5)(A) to 
support issuance of the final rule.

Estimated Take of Marine Mammals

    As mentioned previously, with respect to the MMPA, NMFS' effects 
assessments serve four primary purposes: (1) To prescribe the 
permissible methods of taking (i.e., Level B Harassment (behavioral 
harassment), Level A Harassment (injury), or mortality, including an 
identification of the number and types of take that could occur by 
Level A or B harassment or mortality) and to prescribe other means of 
effecting the least practicable adverse impact on such species or stock 
and its habitat (i.e., mitigation); (2) to determine whether the 
specified activity will have a negligible impact on the affected 
species or stocks of marine mammals (based on the likelihood that the 
activity will adversely affect the species or stock through effects on 
annual rates of recruitment or survival); (3) to determine whether the 
specified activity will have an unmitigable adverse impact on the 
availability of the species or stock(s) for subsistence uses (however, 
there are no subsistence communities in the NAVSEA NUWC Keyport Range 
Complex Study Area; thus, there would be no effect to any subsistence 
user); and (4) to prescribe requirements pertaining to monitoring and 
reporting.
    In the Estimated Take of Marine Mammals section of the proposed 
rule, NMFS related the potential effects to marine mammals from sonar 
operations to the MMPA regulatory definitions of Level A and Level B 
Harassment and assessed the effects to marine mammals that could result 
from the specific activities that the Navy intends to conduct. The 
subsections of this analysis are discussed in the proposed rule (74 FR 
32264; July 7, 2009; pages 32281-32290).
    In the Estimated Exposures of Marine Mammals section of the 
proposed rule, NMFS described in detail how the take estimates were 
calculated through modeling (74 FR 32264; July 7, 2009; pages 32290-
32292). A summary of potential exposures from active acoustic sources 
(per year) for marine mammals in the NAVSEA NUWC Keyport Range Complex 
Study Area is listed in Table 8. No change has been made to the final 
rule.

Effects on Marine Mammal Habitat

    NMFS' NAVSEA NUWC Keyport Range Complex proposed rule included a 
section that addressed the effects of the Navy's activities on Marine 
Mammal habitat (74 FR 32264; July 7, 2009; pages 32292-32293). NMFS 
concluded that the Navy's activities would have minimal effects on 
marine mammal habitat. No changes have been made to the discussion 
contained in this section of the proposed rule.

Analysis and Negligible Impact Determination

    NMFS' NAVSEA NUWC Keyport Range Complex proposed rule included a 
section that addressed the analysis and negligible impact determination 
of the Navy's activities on the affected species or stocks (74 FR 
32264; July 7, 2009; pages 32298-32300).
    The Navy's specified activities have been described based on best 
estimates of the planned RDT&E activities the Navy would conduct within 
the proposed NAVSEA NUWC Keyport Range Complex Extension. The acoustic 
sources proposed to be used in the NAVSEA NUWC Keyport Range Complex 
Extension are low intensity and total proposed sonar operation hours 
are under 1,570 hours. Taking the above into account, along with the 
fact that NMFS anticipates no mortalities and injuries to result from 
the action, the fact that there are no specific areas of reproductive 
importance for marine mammals recognized within the Keyport Range 
Complex Extension study area, the sections discussed below, and 
dependent upon the implementation of the proposed mitigation measures, 
NMFS has determined that Navy RDT&E activities utilizing underwater 
acoustic sources will have a negligible impact on the affected marine 
mammal species and stocks present in the proposed action area.

Behavioral Harassment

    As discussed in the Potential Effects of Exposure of Marine Mammals 
to HFAS/MFAS and illustrated in the conceptual framework, marine 
mammals can respond to HFAS/MFAS in many different ways, a subset of 
which qualifies as harassment. One thing that the take estimates do not 
take into account is the fact that most marine mammals will likely 
avoid strong sound sources to some extent. Although an animal that 
avoids the sound source will likely still be taken in some instances 
(such as if the avoidance results in a missed opportunity to feed, 
interruption of reproductive behaviors, etc.) in other cases avoidance 
may result in fewer instances of take than were estimated or in the 
takes resulting from exposure to a lower received level than was 
estimated, which could result in a less severe response. The Keyport 
Range Complex application involves mid-frequency and high frequency 
active sonar operations shown in Table 2, and none of the tests would 
involve powerful tactical sonar such as the 53C series MFAS. Therefore, 
any disturbance to marine mammals resulting from MFAS and HFAS in the 
proposed Keyport Range Complex RDT&E activities is expected to be 
significantly less in terms of severity when compared to major sonar 
exercises (e.g., AFAST, HRC, SOCAL). In addition, high frequency 
signals tend to have more attenuation in the water column and are more 
prone to lose their energy during propagation. Therefore, their zones 
of influence are much smaller, thereby making it easier to detect 
marine mammals and prevent adverse effects from occurring.
    There is limited information available concerning marine mammal 
reactions to MFAS/HFAS. The Navy has only been conducting monitoring 
activities since 2006. From the four major training exercises (MTEs) of 
HFAS/MFAS in the SOCAL Study Area for which NMFS has received training 
and monitoring reports, no instances of obvious behavioral disturbance 
were observed by the Navy watchstanders. The proposed activities in the 
Keyport Range Complex are RDT&E activities, which are much smaller in 
scale when compared with major training events in SOCAL. One cannot 
conclude from these results that marine mammals were not harassed from 
HFAS/MFAS, as a portion of animals within the area of concern may not 
have been seen (especially those more cryptic, deep-diving species, 
such as beaked whales or Kogia sp.) and some of the non-biologist 
watchstanders might not have had the expertise to characterize 
behaviors. However, the data demonstrate that the animals that were 
observed did not respond in any of the obviously more severe ways, such 
as panic, aggression, or anti-predator response.
    In addition to the monitoring that will be required pursuant to 
these regulations and subsequent LOAs, which is specifically designed 
to help us better understand how marine mammals respond to sound, the 
Navy and NMFS have developed, funded, and begun conducting a controlled 
exposure experiment with beaked whales in the Bahamas.

Diel Cycle

    As noted previously, many animals perform vital functions, such as 
feeding,

[[Page 20272]]

resting, traveling, and socializing on a diel cycle (24-hr cycle). 
Substantive behavioral reactions to noise exposure (such as disruption 
of critical life functions, displacement, or avoidance of important 
habitat) are more likely to be significant if they last more than one 
diel cycle or recur on subsequent days (Southall et al., 2007). 
Consequently, a behavioral response lasting less than one day and not 
recurring on subsequent days is not considered particularly severe 
unless it could directly affect reproduction or survival (Southall et 
al., 2007).
    In the previous section, we discussed the fact that potential 
behavioral responses to HFAS/MFAS that fall into the category of 
harassment could range in severity. By definition, the takes by Level B 
behavioral harassment involve the disturbance of a marine mammal or 
marine mammal stock in the wild by causing disruption of natural 
behavioral patterns (such as migration, surfacing, nursing, breeding, 
feeding, or sheltering) to a point where such behavioral patterns are 
abandoned or significantly altered. These reactions would, however, be 
more of a concern if they were expected to last over 24 hours or be 
repeated in subsequent days. Different sonar testing may not occur 
simultaneously. Some of the marine mammals in the Keyport Range Complex 
Study Area are residents and others would not likely remain in the same 
area for successive days, it is unlikely that animals would be exposed 
to HFAS/MFAS at levels or for a duration likely to result in a 
substantive response that would then be carried on for more than one 
day or on successive days.

TTS

    NMFS and the Navy have estimated that individuals of some species 
of marine mammals may sustain some level of TTS from HFAS/MFAS 
operations. As mentioned previously, TTS can last from a few minutes to 
days, be of varying degree, and occur across various frequency 
bandwidths. The TTS sustained by an animal is primarily classified by 
three characteristics:
    <bullet> Frequency--Available data (of mid-frequency hearing 
specialists exposed to mid to high frequency sounds--Southall et al., 
2007) suggest that most TTS occurs in the frequency range of the source 
up to one octave higher than the source (with the maximum TTS at \1/2\; 
octave above).
    <bullet> Degree of the shift (i.e., how many dB is the sensitivity 
of the hearing reduced by)--generally, both the degree of TTS and the 
duration of TTS will be greater if the marine mammal is exposed to a 
higher level of energy (which would occur when the peak dB level is 
higher or the duration is longer). The threshold for the onset of TTS > 
6 dB) for Navy sonars is 195 dB (SEL), which might be received at 
distances of up to 275-500 m from the most powerful MFAS source, the 
AN/SQS-53 (the maximum ranges to TTS from other sources would be less). 
An animal would have to approach closer to the source or remain in the 
vicinity of the sound source appreciably longer to increase the 
received SEL, which would be difficult considering the marine observers 
and the nominal speed of a sonar vessel (10-12 knots). Of all TTS 
studies, some using exposures of almost an hour in duration or up to 
217 dB SEL, most of the TTS induced was 15 dB or less, though Finneran 
et al. (2007) induced 43 dB of TTS with a 64-sec exposure to a 20 kHz 
source (MFAS emits a 1-s ping 2 times/minute).
    <bullet> Duration of TTS (Recovery time)--see above. Of all TTS 
laboratory studies, some using exposures of almost an hour in duration 
or up to 217 dB SEL, almost all recovered within 1 day (or less, often 
in minutes), though in one study (Finneran et al., 2007), recovery took 
4 days.
    Based on the range of degree and duration of TTS reportedly induced 
by exposures to non-pulse sounds of energy higher than that to which 
free-swimming marine mammals in the field are likely to be exposed 
during HFAS/MFAS testing activities, it is unlikely that marine mammals 
would sustain a TTS from MFAS that alters their sensitivity by more 
than 20 dB for more than a few days (and the majority would be far less 
severe). Also, for the same reasons discussed in the Diel Cycle 
section, and because of the short distance within which animals would 
need to approach the sound source, it is unlikely that animals would be 
exposed to the levels necessary to induce TTS in subsequent time 
periods such that their recovery were impeded. Additionally, though the 
frequency range of TTS that marine mammals might sustain would overlap 
with some of the frequency ranges of their vocalization types, the 
frequency range of TTS from MFAS (the source from which TTS would more 
likely be sustained because the higher source level and slower 
attenuation make it more likely that an animal would be exposed to a 
higher level) would not usually span the entire frequency range of one 
vocalization type, much less span all types of vocalizations.

Acoustic Masking or Communication Impairment

    As discussed above, it is also possible that anthropogenic sound 
could result in masking of marine mammal communication and navigation 
signals. However, masking only occurs during the time of the signal 
(and potential secondary arrivals of indirect rays), versus TTS, which 
occurs continuously for its duration. Masking effects from HFAS/MFAS 
are expected to be minimal. If masking or communication impairment were 
to occur briefly, it would be in the frequency range of MFAS, which 
overlaps with some marine mammal vocalizations; however, it would 
likely not mask the entirety of any particular vocalization or 
communication series because the pulse length, frequency, and duty 
cycle of the HFAS/MFAS signal does not perfectly mimic the 
characteristics of any marine mammal's vocalizations.

PTS, Injury, or Mortality

    The Navy's model estimated that no marine mammal would be taken by 
Level A harassment (injury, PTS included) or mortality due to the low 
intensity of the active sound sources being used.
    Based on the aforementioned assessment, NMFS determines that there 
would be the following number of takes: 11,283 harbor porpoises, 44 
northern fur seals, 114 California sea lions, 14 northern elephant 
seals, and 5,569 harbor seals (5,468 Washington Inland Waters stock and 
101 Oregon/Washington Coastal stock) by Level B harassment (TTS and 
sub-TTS) as a result of the proposed Keyport Range Complex RDT&E sonar 
testing activities. These numbers very likely do not represent the 
number of individuals that would be taken, since it's most likely that 
many individual marine mammals would be taken multiple times. However, 
if each take represents a different animal, these take numbers 
represent approximately 29.89%, 0.01%, 0.05%, 0.01%, 37.42%, and 0.41% 
of the Oregon/Washington Coastal stock harbor porpoises, Eastern 
Pacific stock northern fur seals, U.S. stock California sea lions, 
California breeding stock northern elephant seals, Washington Inland 
Waters stock harbor seals, and Oregon/Washington Coastal stock harbor 
seals, respectively, in the vicinity of the proposed Keyport Range 
Complex Study Area (calculation based on NMFS 2007 U.S. Pacific Marine 
Mammal Stock Assessments and 2007 U.S. Alaska Marine Mammal Stock 
Assessments).

[[Page 20273]]

    No Level A take (injury, PTS included) or mortality would occur as 
the result of the proposed RDT&E and range extension activities for the 
Keyport Range Complex.
    Based on these analyses, NMFS has determined that the total taking 
over the 5-year period of the regulations and subsequent LOAs from the 
Navy's NAVSEA NUWCX Keyport Range Complex RDT&E and range extension 
activities will have a negligible impact on the marine mammal species 
and stocks present in the Keyport Range Complex Study Area. No changes 
have been made to the discussion contained in this section of the 
proposed rule.

Subsistence Harvest of Marine Mammals

    NMFS has determined that the total taking of marine mammal species 
or stocks from the Navy's mission activities in the Keyport Range 
Complex study area would not have an unmitigable adverse impact on the 
availability of the affected species or stocks for subsistence uses, 
since there are no such uses in the specified area.

ESA

    There are eight marine mammal species/stocks, one sea turtle 
species, and four fish species over which NMFS has jurisdiction that 
are listed as endangered or threatened under the ESA that could occur 
in the NAVSEA NUWC Keyport Range Complex study area: Blue whale, fin 
whale, sei whale, humpback whale, North Pacific right whale, sperm 
whale, Southern Resident killer whale, Steller sea lions, leatherback 
sea turtle, Puget Sound Chinook salmon, Hood Canal summer-run chum 
salmon, Puget Sound Steelhead trout, and Coastal-Puget Sound bull 
trout.
    Pursuant to Section 7 of the ESA, the Navy has consulted with NMFS 
on this action. NMFS has also consulted internally on the issuance of 
regulations under section 101(a)(5)(A) of the MMPA for this activity. 
NMFS' Biological Opinion concludes that the proposed RDT&E activities 
are not likely to jeopardize the continued existence of the threatened 
and endangered species listed under the ESA under NMFS jurisdiction.

NEPA

    NMFS participated as a cooperating agency on the Navy's Final 
Environmental Impact Statement (FEIS) for the NAVSEA NUWC Keyport Range 
Complex, published on May 12, 2010. NMFS has adopted the Navy's EIS/
OEIS in connection with this MMPA rulemaking and has prepared a record 
of decision.

Determination

    Based on the analysis contained herein and in the proposed rule 
(and other related documents) of the likely effects of the specified 
activity on marine mammals and their habitat and dependent upon the 
implementation of the mitigation and monitoring measures, NMFS finds 
that the total taking from the NAVSEA NUWC Keyport Range Complex's 
RDT&E activities utilizing active acoustic sources (including MFAS/
HFAS) over the 5 year period will have a negligible impact on the 
affected species or stocks and will not result in an unmitigable 
adverse impact on the availability of marine mammal species or stocks 
for taking for subsistence uses. NMFS has issued regulations for these 
exercises that prescribe the means of effecting the least practicable 
adverse impact on marine mammals and their habitat and set forth 
requirements pertaining to the monitoring and reporting of that taking.

Classification

    This action does not contain a collection of information 
requirement for purposes of the Paperwork Reduction Act.
    This proposed rule has been determined by the Office of Management 
and Budget to be not significant for purposes of Executive Order 12866.
    Pursuant to the Regulatory Flexibility Act, the Chief Counsel for 
Regulation of the Department of Commerce certified to the Chief Counsel 
for Advocacy of the Small Business Administration at the proposed rule 
stage that this rule, if adopted, would not have a significant economic 
impact on a substantial number of small entities, and published such 
certification in the Federal Register notice of proposed rulemaking. No 
changes have been made that affect that certification. Accordingly, no 
final regulatory flexibility analysis is required, and none has been 
prepared.
    The Assistant Administrator for Fisheries has determined that there 
is good cause under the Administrative Procedure Act (5 U.S.C. 
553(d)(3)) to waive the 30-day delay in effective date of the measures 
contained in the final rule. The Navy has a compelling national policy 
reason to continue military readiness activities without interruption 
in the Keyport Range Complex. As discussed below, suspension/
interruption of the Navy's ability to conduct RDT&E activities disrupts 
adequate and realistic testing of military equipment, vehicles, 
weapons, and sensors for proper operation and suitability for combat 
essential to our national security.
    In order to meet its national security objectives, the Navy must 
continually maintain its ability to operate in a challenging at-sea 
environment, conduct military operations, control strategic maritime 
transit routes and international straits, and protect sea lines of 
communications that support international commerce. To meet these 
objectives, the Navy must identify, develop, and procure defense 
systems by continually integrating test and evaluation support 
throughout the defense acquisition process and providing essential 
information to decision-makers. Such testing and evaluation is critical 
in determining that a defense system performs as expected and whether 
these systems are operationally effective, suitable, survivable, and 
safe for their intended use.
    In order to effectively fulfill its national security mission, the 
Navy has a need to conduct RDT&E activities covered by this final rule 
as soon as possible. The defense acquisition process is structured to 
be responsive and acquire quality products that satisfy user needs with 
measurable improvements on mission capability and operational support 
in a timely manner. Test and evaluation confirms performance of 
platforms and systems against documented capability needs and adversary 
capabilities. Delays in acquisition test and evaluation affect the 
Navy's need to meet its statutory mission to deploy worldwide naval 
forces equipped to meet existing and emergent threats. The Navy has and 
will be unable to plan to conduct activities covered by this final rule 
in the immediate future due to the uncertainties in the planning 
process and the fiscal and other consequences of planning for, 
preparing for, and then cancelling a major testing event. A 30-day 
delay furthers the amount of time the Navy is unable to plan for and 
execute an activity covered by this rule. Further, should an immediate 
national security requirement to use the range complex arise, the 30 
day delay would prevent the Navy from meeting its mission. This would 
have adverse national security consequences.
    Waiver of the 30-day delay of the effective date of the final rule 
will allow the Navy to continue to integrate RDT&E activities into the 
defense acquisition process to meet test and evaluation requirements, 
and to put capability into the hands of U.S. Sailors and Marines 
quickly.

requirements of these regulations or a Letter of Authorization issued 
under Sec.  216.106 of this chapter and Sec.  218.176.


Sec.  218.173  Mitigation.

    When conducting RDT&E activities identified in Sec.  218.170(c), 
the mitigation measures contained in this subpart and subsequent 
Letters of Authorization issued under Sec.  216.106 of this chapter and 
Sec.  218.176 must be implemented. These mitigation measures include, 
but are not limited to:
    (a) Marine mammal observers training:
    (1) All range personnel shall be trained in marine mammal 
recognition.
    (2) Marine mammal observer training shall be conducted by qualified 
organizations approved by NMFS.
    (b) Lookouts onboard vessels:
    (1) Vessels on a range shall use lookouts during all hours of range 
activities.
    (2) Lookout duties include looking for marine mammals.
    (3) All sightings of marine mammals shall be reported to the Range 
Officer in charge of overseeing the activity.
    (c) Visual surveillance shall be conducted just prior to all in-
water exercises.
    (1) Surveillance shall include, as a minimum, monitoring from all 
participating surface craft and, where available, adjacent shore sites.
    (2) When cetaceans have been sighted in the vicinity of the 
operation, all range participants increase vigilance and take 
reasonable and practicable actions to avoid collisions and activities 
that may result in close interaction of naval assets and marine 
mammals.
    (3) Actions may include changing speed and/or direction, subject to 
environmental and other conditions (e.g., safety, weather).
    (d) An ``exclusion zone'' shall be established and surveillance 
will be conducted to ensure that there are no marine mammals within 
this exclusion zone prior to the commencement of each in-water 
exercise.
    (1) For cetaceans, the exclusion zone shall extend out 1,000 yards 
(914.4 m) from the intended track of the test unit.
    (2) For pinnipeds, the exclusion zone shall extend out 100 yards 
(91 m) from the intended track of the test unit.
    (e) Range craft shall not approach within 100 yards (91 m) of 
marine mammals, to the extent practicable considering human and vessel 
safety priorities. This includes marine mammals ``hauled-out'' on 
islands, rocks, and other areas such as buoys.
    (f) In the event of a collision between a Navy vessel and a marine 
mammal, NUWC Keyport activities shall notify immediately the Navy chain 
of Command, which shall notify NMFS immediately.
    (g) Passive acoustic monitoring for cetaceans will be implemented 
throughout the NUWC Keyport Range Complex during RDT&E testing 
activities involving active sonar transmissions when passive acoustic 
monitoring capabilities are being operated during the testing activity.
    (h) Procedures for reporting marine mammal sightings on the NAVSEA

[[Page 20276]]

NUWC Keyport Range Complex shall be promulgated, and sightings shall be 
entered into the Range Operating System and forwarded to NOAA/NMML 
Platforms of Opportunity Program.
    (i) If there is clear evidence that a marine mammal is injured or 
killed as a result of the proposed Navy RDT&E activities, the Naval 
activities shall be immediately suspended and the situation immediately 
reported by personnel involved in the activity to the Ranger Officer, 
who will follow Navy procedures for reporting the incident to NMFS 
through the Navy's chain-of-command.
    (j) For nighttime RDT&E activities of active acoustic transmissions 
in the Keyport Range proposed extension area, the Navy shall conduct 
passive acoustic monitoring within the Agate Pass and south of 
University Point in southern Port Orchard Reach. If Southern Resident 
killer whales are detected in the vicinity of the Keyport Range Site, 
the Range Office shall be notified immediately and the active acoustic 
sources must be shutdown if killer whales are confirmed to approach at 
1,000 yards from the source.


Sec.  218.174  Requirements for monitoring and reporting.

    (a) The Holder of the Letter of Authorization issued pursuant to 
Sec.  216.106 of this chapter and Sec.  218.176 for activities 
described in Sec.  218.170(c) is required to cooperate with the NMFS 
when monitoring the impacts of the activity on marine mammals.
    (b) The Holder of the Authorization must notify NMFS immediately 
(or as soon as clearance procedures allow) if the specified activity 
identified in Sec.  218.170(c) is thought to have resulted in the 
mortality or injury of any marine mammals, or in any take of marine 
mammals not identified or authorized in Sec.  218.171(c).
    (c) The Navy must conduct all monitoring and required reporting 
under the Letter of Authorization, including abiding by the NAVSEA NUWC 
Keyport Range Complex Monitoring Plan, which is incorporated herein by 
reference, and which requires the Navy to implement, at a minimum, the 
monitoring activities summarized below:
    (1) Visual Surveys:
    (i) The Holder of this Authorization shall conduct a minimum of 2 
special visual surveys per year to monitor HFAS and MFAS respectively 
at the DBRC Range site.
    (ii) For specified events, shore-based and vessel surveys shall be 
used 1 day prior to and 1-2 days post activity.
    (A) Shore-based Surveys:
    (1) Shore-based monitors shall observe test events that are planned 
in advance to occur adjacent to near shore areas where there are 
elevated topography or coastal structures, and shall use binoculars or 
theodolite to augment other visual survey methods.
    (2) Shore-based surveys of the test area and nearby beaches shall 
be conducted for stranded marine animals following nearshore events. If 
any distressed, injured or stranded animals are observed, an assessment 
of the animal's condition (alive, injured, dead, or degree of 
decomposition) shall be reported immediately to the Navy and the 
information shall be transmitted immediately to NMFS through the 
appropriate chain of command.
    (B) Vessel-based Surveys:
    (1) Vessel-based surveys shall be designed to maximize detections 
of marine mammals near mission activity event.
    (2) Post-analysis shall focus on how the location, speed and vector 
of the range craft and the location and direction of the sonar source 
(e.g. Navy surface vessel) relates to the animal.
    (3) Any other vessels or aircraft observed in the area shall also 
be documented.
    (iii) Surveys shall include the range site with special emphasis 
given to the particular path of the test run. When conducting a 
particular survey, the survey team shall collect the following 
information.
    (A) Species identification and group size;
    (B) Location and relative distance from the acoustic source(s);
    (C) The behavior of marine mammals including standard environmental 
and oceanographic parameters;
    (D) Date, time and visual conditions associated with each 
observation;
    (E) Direction of travel relative to the active acoustic source; and
    (F) Duration of the observation.
    (iv) Animal sightings and relative distance from a particular 
active acoustic source shall be used post-survey to determine potential 
received energy (dB re 1 micro Pa-sec). This data shall be used, post-
survey, to estimate the number of marine mammals exposed to different 
received levels (energy based on distance to the source, bathymetry, 
oceanographic conditions and the type and power of the acoustic source) 
and their corresponding behavior.
    (2) Passive Acoustic Monitoring (PAM):
    (i) The Navy shall deploy a hydrophone array in the Keyport Range 
Complex Study Area for PAM.
    (ii) The array shall be utilized during the two special monitoring 
surveys in DBRC as described in Sec.  218.174(c)(1)(i).
    (iii) The array shall have the capability of detecting low 
frequency vocalizations (<1,000 Hz) for baleen whales and relatively 
high frequency (up to 30 kHz) for odontocetes.
    (iv) Acoustic data collected from the PAM shall be used to detect 
acoustically active marine mammals as appropriate.
    (3) Marine Mammal Observers on range craft or Navy vessels:
    (i) Navy Marine mammal observers (NMMOs) may be placed on a range 
craft or Navy platform during the event being monitored.
    (ii) The NMMO must possess expertise in species identification of 
regional marine mammal species and experience collecting behavioral 
data.
    (iii) NMMOs may be placed alongside existing lookouts during the 
two specified monitoring events as described in Sec.  218.174(c)(1)(i).
    (iv) NMMOs shall inform the lookouts of any marine mammal sighting 
so that appropriate action may be taken by the chain of command. NMMOs 
shall schedule their daily observations to duplicate the lookouts' 
schedule.
    (v) NMMOs shall observe from the same height above water as the 
lookouts, and they shall collect the same data collected by lookouts 
listed in Sec.  218.174(c)(1)(iii).
    (d) The Navy shall complete an Integrated Comprehensive Monitoring 
Program (ICMP) Plan in 2009. This planning and adaptive management tool 
shall include:
    (1) A method for prioritizing monitoring projects that clearly 
describes the characteristics of a proposal that factor into its 
priority.
    (2) A method for annually reviewing, with NMFS, monitoring results, 
Navy R&D, and current science to use for potential modification of 
mitigation or monitoring methods.
    (3) A detailed description of the Monitoring Workshop to be 
convened in 2011 and how and when Navy/NMFS will subsequently utilize 
the findings of the Monitoring Workshop to potentially modify 
subsequent monitoring and mitigation.
    (4) An adaptive management plan.
    (5) A method for standardizing data collection for NAVSEA NUWC 
Keyport Range Complex Extension and across range complexes.
    (e) Notification of Injured or Dead Marine Mammals--Navy personnel 
shall ensure that NMFS (regional stranding coordinator) is notified 
immediately (or as soon as clearance procedures allow) if an injured or 
dead marine mammal is found during or

[[Page 20277]]

shortly after, and in the vicinity of, any Navy activities utilizing 
sonar. The Navy shall provide NMFS with species or description of the 
animal(s), the condition of the animal(s) (including carcass condition 
if the animal is dead), location, time of first discovery, observed 
behaviors (if alive), and photo or video (if available).
    (f) Annual Keyport Range Complex Monitoring Plan Report--The Navy 
shall submit a report annually by December 1 describing the 
implementation and results (through September 1 of the same year) of 
the Keyport Range Complex Monitoring Plan. Data collection methods will 
be standardized across range complexes to allow for comparison in 
different geographic locations. Although additional information will 
also be gathered, the NMMOs collecting marine mammal data pursuant to 
the Keyport Range Complex Monitoring Plan shall, at a minimum, provide 
the same marine mammal observation data required in Sec.  218.174(c). 
The Keyport Range Complex Monitoring Plan Report may be provided to 
NMFS within a larger report that includes the required Monitoring Plan 
Reports from Keyport Range Complex and multiple range complexes.
    (g) Keyport Range Complex 5-yr Comprehensive Report--The Navy shall 
submit to NMFS a draft comprehensive report that analyzes and 
summarizes all of the multi-year marine mammal information gathered 
during tests involving active acoustic sources for which individual 
reports are required in Sec.  218.174 (d)-(f). This report will be 
submitted at the end of the fourth year of the rule (June 2013), 
covering activities that have occurred through September 1, 2013.
    (h) The Navy shall respond to NMFS comments and requests for 
additional information or clarification on the Keyport Range Complex 
Extension Comprehensive Report, the Annual Keyport Range Complex 
Monitoring Plan Report (or the multi-Range Complex Annual Monitoring 
Report, it that is how the Navy chooses to submit the information) if 
submitted within 3 months of receipt. The report will be considered 
final after the Navy has addressed NMFS' comments, or three months 
after the submittal of the draft if NMFS does not comment by then.
    (i) In 2011, the Navy shall convene a Monitoring Workshop in which 
the Monitoring Workshop participants will be asked to review the Navy's 
Monitoring Plans and monitoring results and make individual 
recommendations (to the Navy and NMFS) of ways of improving the 
Monitoring Plans. The recommendations shall be reviewed by the Navy, in 
consultation with NMFS, and modifications to the Monitoring Plan shall 
be made, as appropriate.


Sec.  218.175  Applications for Letters of Authorization.

    To incidentally take marine mammals pursuant to these regulations 
for the activities identified in Sec.  218.170(c), the U.S. Navy must 
apply for and obtain either an initial Letter of Authorization in 
accordance with Sec.  218.176 or a renewal under Sec.  218.177.


Sec.  218.176  Letters of Authorization.

    (a) A Letter of Authorization, unless suspended or revoked, will be 
valid for a period of time not to exceed the period of validity of this 
subpart, but must be renewed annually subject to annual renewal 
conditions in Sec.  218.177.
    (b) Each Letter of Authorization will set forth:
    (1) Permissible methods of incidental taking;
    (2) Means of effecting the least practicable adverse impact on the 
species, its habitat, and on the availability of the species for 
subsistence uses (i.e., mitigation); and
    (3) Requirements for mitigation, monitoring and reporting.
    (c) Issuance and renewal of the Letter of Authorization will be 
based on a determination that the total number of marine mammals taken 
by the activity as a whole will have no more than a negligible impact 
on the affected species or stock of marine mammal(s).


Sec.  218.177  Renewal of Letters of Authorization and adaptive 
management.

    (a) A Letter of Authorization issued under Sec.  216.106 and Sec.  
218.176 for the activity identified in Sec.  218.170(c) will be renewed 
annually upon:
    (1) Notification to NMFS that the activity described in the 
application submitted under Sec.  218.175 shall be undertaken and that 
there will not be a substantial modification to the described work, 
mitigation or monitoring undertaken during the upcoming 12 months;
    (2) Timely receipt of the monitoring reports required under Sec.  
218.174(b); and
    (3) A determination by the NMFS that the mitigation, monitoring and 
reporting measures required under Sec.  218.173 and the Letter of

undertaken and will be undertaken during the upcoming annual period of 
validity of a renewed Letter of Authorization.
    (b) If a request for a renewal of a Letter of Authorization issued 
under Sec. Sec.  216.106 and 218.177 indicates that a substantial 
modification to the described work, mitigation or monitoring undertaken 
during the upcoming season will occur, the NMFS will provide the public 
a period of 30 days for review and comment on the request. Public 
comment on renewals of Letters of Authorization are restricted to:
    (1) New cited information and data indicating that the 
determinations made in this document are in need of reconsideration, 
and
    (2) Proposed changes to the mitigation and monitoring requirements 
contained in these regulations or in the current Letter of 
Authorization.
    (c) A notice of issuance or denial of a renewal of a Letter of 
Authorization will be published in the Federal Register.
    (d) NMFS, in response to new information and in consultation with 
the Navy, may modify the mitigation or monitoring measures in 
subsequent LOAs if doing so creates a reasonable likelihood of more 
effectively accomplishing the goals of mitigation and monitoring set 
forth in the preamble of these regulations. Below are some of the 
possible sources of new data that could contribute to the decision to 
modify the mitigation or monitoring measures:
    (1) Results from the Navy's monitoring from the previous year 
(either from Keyport Range Complex Study Area or other locations).
    (2) Findings of the Monitoring Workshop that the Navy will convene 
in 2011 (Sec.  218.174(i)).

    (5) Results from the Long Term Prospective Study described in the 
preamble to these regulations.
    (6) Results from general marine mammal and sound research (funded 
by the Navy (described below) or otherwise).
    (7) Any information which reveals that marine mammals may have been 
taken in a manner, extent or number not authorized by these regulations 
or subsequent Letters of Authorization.


Sec.  218.178  Modifications to Letters of Authorization.

    (a) Except as provided in paragraph (b) of this section and Sec.  
218.177(d), no substantive modification (including withdrawal or 
suspension) to the Letter of Authorization by NMFS, issued

[[Page 20278]]

pursuant to Sec.  216.106 of this chapter and Sec.  218.176 and subject 
to the provisions of this subpart shall be made until after 
notification and an opportunity for public comment has been provided. 
For purposes of this paragraph, a renewal of a Letter of Authorization 
under Sec.  218.177, without modification (except for the period of 
validity), is not considered a substantive modification.
    (b) If the Assistant Administrator determines that an emergency 
exists that poses a significant risk to the well-being of the species 
or stocks of marine mammals specified in Sec.  218.171(b), a Letter of 
Authorization issued pursuant to Sec.  216.106 of this chapter and 
Sec.  218.176 may be substantively modified without prior notification 
and an opportunity for public comment. Notification will be published 
in the Federal Register within 30 days subsequent to the action.
