Amendments to the North Atlantic Right Whale Vessel Strike 
Reduction Rule

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

[[Page 46922]]


ACTION: Proposed rule.

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

SUMMARY: NMFS is proposing changes to the North Atlantic right whale 
(Eubalaena glacialis) vessel speed regulations to further reduce the 
likelihood of mortalities and serious injuries to endangered right 
whales from vessel collisions, which are a leading cause of the 
species' decline and a primary factor in an ongoing Unusual Mortality 
Event. The proposed rule would: (1) modify the spatial and temporal 
boundaries of current speed restriction areas referred to as Seasonal 
Management Areas (SMAs), (2) include most vessels greater than or equal 
to 35 ft (10.7 m) and less than 65 ft (19.8 m) in length in the size 
class subject to speed restriction, (3) create a Dynamic Speed Zone 
framework to implement mandatory speed restrictions when whales are 
known to be present outside active SMAs, and (4) update the speed 
rule's safety deviation provision. Changes to the speed regulations are 
proposed to reduce vessel strike risk based on a coast-wide collision 
mortality risk assessment and updated information on right whale 
distribution, vessel traffic patterns, and vessel strike mortality and 
serious injury events. Changes to the existing vessel speed regulation 
are essential to stabilize the ongoing right whale population decline 
and prevent the species' extinction.

SUPPLEMENTARY INFORMATION:

Background

    The North Atlantic right whale (Eubalaena glacialis) was severely 
depleted by commercial whaling and, despite protection from commercial 
harvest since 1935, has not recovered. Following two decades of growth 
between 1990 and 2010, the species has been in decline over the past 
decade (Pace et al. 2017; Pace 2021), with a recent preliminary 
population estimate of fewer than 350 individuals remaining. North 
Atlantic right whale abundance began to decline in 2010 due to a 
combination of increased human-caused mortality and decreased 
reproductive output (Pace et al. 2017). The decline coincided with 
changes in whale habitat use patterns, characterized by the whales' 
increasing use of areas with few protections from anthropogenic harm 
(Davis et al. 2017; Meyer-Gutbrod and Greene 2018; Record et al. 2019). 
The species' decline has been exacerbated by an ongoing Unusual 
Mortality Event (UME) that NMFS declared in 2017, pursuant to section 
404 of the Marine Mammal Protection Act (MMPA), and includes an 
unprecedented 51 known mortalities and serious injuries to date, 
impeding the species' recovery. NMFS interprets the regulatory 
definition of serious injury as any injury that is ``more likely than 
not'' to result in mortality, or any injury that presents a greater 
than 50 percent chance of death to a marine mammal (NMFS 2014). Thus, 
lethal strike events are those that have or are likely to result in a 
mortality.
    Entanglement in fishing gear and vessel strikes are the two primary 
causes of right whale mortality and serious injury. Human-caused 
mortality to adult females, in particular, is limiting recovery of the 
species (Moore et al. 2005, 2021; Corkeron et al. 2018; Hayes et al. 
2019; Sharp et al. 2019). Anthropogenic trauma was the sole source of 
mortality for right whale adults and juveniles for which a cause of 
death could be determined between 2003 and 2018 (Sharp et al. 2019). 
North Atlantic right whale calving rates dropped from 2017 to 2020, 
with zero births recorded during the 2017-2018 season. The 2020-2021 
calving season had the first substantial calving increase in five 
years, with 20 calves born, followed by 15 calves during the 2021-2022 
calving season. However, mortalities continue to outpace births, and 
best estimates indicate fewer than 100 reproductively active females 
remain in the population.
    NMFS has determined that the Potential Biological Removal (PBR) for 
the species--defined by the MMPA as ``the maximum number of 
individuals, not including natural mortalities, that may be removed 
from a marine mammal stock while allowing that stock to reach or 
maintain its optimum sustainable population''--is 0.7 whales (NMFS 
2021). This means that for the species to recover, the population 
cannot sustain, on average over the course of a year, the death or 
serious injury of a single individual due to human causes. Observed 
human caused mortality far exceeds this level and a recent assessment 
of total right whale mortality estimates range-wide indicates that 
observed deaths likely captured only about 36 percent of the actual 
total deaths between 1990 and 2017 (Pace et al. 2021). Right whale 
abundance will continue to decline, imperiling species recovery, unless 
human caused mortality is substantially reduced in the near term.
    North Atlantic right whales inhabit U.S. waters year-round but 
predominate during late fall through early summer. Within U.S. waters, 
the whales primarily forage in the greater Gulf of Maine region 
(Pershing et al. 2009; Davies et al. 2014). The species' only known 
winter calving area lies within the South Atlantic Bight between 
northern Florida and North Carolina (Keller et al. 2012; Gowan and 
Ortega-Ortiz 2014). The Mid-Atlantic region serves both as a migratory 
habitat for whales moving between calving areas and northern foraging 
grounds, as well as a foraging habitat. Right whales can be highly 
mobile, traveling upwards of 40 nautical miles per day, or, when 
engaged in certain behaviors (e.g., foraging), relatively stationary, 
remaining within several miles for days (Baumgartner and Mate 2005; 
Crowe et al. 2021). The whales' primary distribution includes seasonal 
coastal habitats characterized by extensive commercial and recreational 
vessel traffic.
    North Atlantic right whales are vulnerable to vessel strike due to 
their coastal distribution and frequent occurrence at near-surface 
depths, and this is particularly true for females with calves. The 
proportion of known vessel strike events involving females, calves,

[[Page 46923]]

and juveniles is higher than their representation in the population 
(NMFS 2020). Mother/calf pairs are at high risk of vessel strike 
because they frequently rest and nurse in nearshore habitats at or near 
the water surface, particularly in the Southeast calving area (Cusano 
et al. 2018; Dombroski et al. 2021). Calving females have the longest 
residence time of any demographic group on the Southeast calving 
ground, staying on average about three months in the region before 
traveling with their nursing calves to northern foraging areas 
(Krzystan et al. 2018). Right whales nurse their calves for up to a 
year. This promotes rapid calf growth (Fortune et al. 2012) but also 
places mother/calf pairs at increased risk of vessel interactions, not 
only within the Southeast calving ground but also along the Mid-
Atlantic and New England coasts, which are important migratory and 
foraging areas for right whales.
    Numerous studies have indicated that slowing the speed of vessels 
reduces the risk of lethal vessel collisions, particularly in areas 
where right whales are abundant and vessel traffic is common and 
otherwise traveling at high speeds (Vanderlaan and Taggart 2007; Conn 
and Silber 2013; Van der Hoop et al. 2014; Martin et al. 2015; Crum et 
al. 2019). In 2008, NMFS implemented 10-knot (5.1 meters/second (m/s)) 
vessel speed restrictions for a five-year period for most vessels 
greater than or equal to 65 ft (19.8 m) in overall length within 
designated areas commonly referred to as Seasonal Management Areas 
(SMAs) along the U.S. East Coast to reduce the risk of mortality and 
serious injury from vessel strike (73 FR 60173, October 10, 2008 (50 
CFR 224.105)). NMFS later removed the five-year ``sunset'' provision 
from the speed rule (78 FR 73726, December 9, 2013; 79 FR 34245, June 
16, 2014), and the rule continues in effect today.
    Reducing vessel speed is one of the most effective, feasible 
options available to reduce the likelihood of lethal outcomes from 
vessel collisions with right whales. Previous investigations indicate 
that NMFS' speed regulations at 50 CFR 224.105 for most vessels greater 
than or equal to 65 ft (19.8 m) in length reduced the risk of lethal 
vessel strikes to right whales (Conn and Silber 2013; Laist et al. 
2014). In 2021, NMFS released the North Atlantic Right Whale Vessel 
Speed Rule Assessment (hereafter ``speed rule assessment'') documenting 
a reduction in observed right whale serious injuries and mortalities 
resulting from vessel strikes since implementation of the speed rule in 
2008 (50 CFR 224.105), but highlighting the need for additional action 
to more effectively address the risk of vessel strikes to right whales 
(NMFS 2020).
    NMFS is addressing risk from fishing gear entanglement through 
separate regulatory actions from this proposed rule as informed by the 
Atlantic Large Whale Take Reduction Team (ALWTRT) and continues to work 
on additional measures to further reduce lethal entanglements. The MMPA 
directs NMFS to reduce incidental entanglements in commercial fisheries 
that cause mortalities and serious injuries of marine mammal stocks 
above a biological reference point (i.e. PBR) through a consensus-based 
Take Reduction Process. The ALWTRT is a large stakeholder group NMFS 
has convened numerous times since 1996 to develop recommendations to 
reduce mortality and serious injury of right whales and other large 
whales covered under the Atlantic Large Whale Take Reduction Plan. The 
ALWTRT continues to meet regularly to develop recommendations to 
further modify the Plan and reduce right whale entanglements in 
commercial fisheries.

Summary of Current North Atlantic Right Whale Vessel Strike Reduction 
Measures

    NMFS has implemented a combination of regulatory requirements and 
voluntary programs aimed at modifying mariner behavior and/or 
increasing mariner awareness of right whale presence to reduce vessel 
collision risk. Together, these efforts address two aspects of reducing 
strike risk: (1) reducing the spatial overlap of right whales and 
vessels, and (2) reducing the speed of vessels in areas and at times 
when right whales are likely to be present. Below is a summary of 
vessel strike reduction actions implemented by NMFS and other Federal 
partners to date.

Statutory Protections

    (1) ``Take'' Prohibitions. Both the Endangered Species Act (ESA) 
and the MMPA generally prohibit the unauthorized ``take'' of North 
Atlantic right whales. Under the ESA, ``take means to harass, harm, 
pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to 
attempt to engage in any such conduct.'' (16 U.S.C. 1532(19)). Under 
the MMPA, ``take means to harass, hunt, capture, or kill, or attempt to 
harass, hunt, capture, or kill.'' (16 U.S.C. 1362(13)).
    (2) ESA Section 7 Consultations. As required by Section 7(a)(2) of 
the ESA, as amended (ESA; 16 U.S.C. 1531 et seq.), all U.S. Federal 
agencies must consult with NMFS to ensure that any actions they 
authorize, fund, or carry out that may affect ESA-listed species under 
NMFS jurisdiction are not likely to jeopardize the continued existence 
of those species or adversely modify or destroy their designated 
critical habitat. When Federal agencies authorize vessel activities 
potentially co-occurring with right whales and engage in consultations 
with NMFS, they often implement measures governing vessel speed 
designed to reduce the risk of right whale interactions.

Regulatory Measures

    (1) North Atlantic Right Whale Vessel Speed Rule. In 2008, NMFS 
implemented a rule requiring most vessels equal to or greater than 65 
ft (19.8 m) in length to transit at speeds of 10 knots (5.1 m/s) or 
less in designated SMAs (73 FR 60173, October 10, 2008) pursuant to its 
authority under the MMPA and ESA. Some vessels are exempt from this 
requirement including military vessels, vessels owned, operated or 
contracted by the Federal government, and vessels engaged in 
enforcement or search and rescue activities (50 CFR 224.105(a)). 
Although these vessels are exempt from the speed rule, they are not 
exempt from consultation under section 7 of the ESA. During 
consultations, mitigation measures, including reduced speeds, may be 
recommended or specified to reduce the threat of vessels collisions 
with right whales. Regulatory requirements, such as those proposed here 
that contain a maximum vessel speed but no minimum, are separate from 
any requirements specified as part of ESA section 7 consultations and 
are not expected to result in the need to reinitiate existing 
consultations (50 CFR 402.16). In addition, subject to specific 
requirements, vessels may deviate from the speed restriction (i.e., 
exceed the speed limit), under limited circumstances, to maintain safe 
maneuvering speeds (50 CFR 224.105(c)). Vessels employing this safety 
deviation must make a notation in the vessel logbook detailing the 
event. Ten SMAs were designated along the U.S. East Coast with 
seasonally active periods reflective of temporal trends in right whale 
habitat use. The locations of the SMAs were informed by vessel traffic 
(i.e., port entrances were assumed high traffic areas relative to other 
areas) and right whale distribution data at the time the rule was 
established. NMFS selected the 10-knot (5.1 m/s) speed limit based on 
analyses of large whale vessel strike events where the vessel speed at 
the time of impact was known. Researchers found the probability of 
whale mortality increased substantially

[[Page 46924]]

with vessel speed, with the greatest increase occurring between speed 
of 10 to 14 knots (5.1 to 7.2 m/s; Vanderlaan and Taggert 2007). Based 
on these findings, NMFS determined that the use of speed restrictions 
was an effective means to reduce the likelihood and severity of vessel 
collisions.
    (2) 500 Yard (457.2 m) Minimum Approach Distance. In 1997, NMFS 
implemented a minimum approach distance for vessels in the vicinity of 
North Atlantic right whales in an effort to reduce harassment and risk 
of injury (62 FR 6729, February 13, 1997). It is illegal for a vessel 
to approach within 500 yards (457.2 m) of a right whale, and if a 
vessel finds itself within 500 yards (457.2 m) it ``must steer a course 
away from the right whale and immediately leave the area at a slow safe 
speed'' (50 CFR 224.103(c)(1-2)). Exceptions are made if ``compliance 
would create an imminent or serious threat to a . . . vessel'' (50 CFR 
224.103(c)(3)).

Non-Regulatory Measures

    (1) Great South Channel Area To Be Avoided (ATBA). An ATBA is an 
International Maritime Organization (IMO)-established vessel routing 
measure within a specified area to avoid navigational hazards or 
environmentally sensitive areas. In June 2009, an ATBA was established 
in the Great South Channel to the east of Cape Cod, MA after gaining 
approval from the IMO. All vessels greater than or equal to 300 gross 
tons are recommended to avoid this area between April 1 and July 31.
    (2) Recommended Routes. In 2006, a joint U.S. Coast Guard/NOAA 
effort established recommended routes for vessels transiting across 
Cape Cod Bay and into/out of ports in Florida and Georgia. The routes 
are recommended between January and May in Cape Cod Bay and between 
November and April off Florida and Georgia. Mariners are recommended to 
follow the routes to minimize their transit distance through important 
right whale habitat areas.
    (3) Modification to the Boston Traffic Separation Scheme (TSS). In 
2007, following a successful application to the IMO led by the 
Stellwagen Bank National Marine Sanctuary and NMFS, a modified TSS 
(commonly referred to as a shipping lane) was implemented to the north 
of Cape Cod, MA for vessel traffic navigating to and from the Port of 
Boston. The modification narrowed the TSS and shifted its route to the 
north around Cape Cod to reduce the overlap with large whale foraging 
grounds.
    (4) Dynamic Management Areas (DMAs) and Right Whale Slow Zones. 
NMFS implemented a voluntary DMA program concurrently with the 
mandatory speed rule in 2008. A DMA is triggered when a group of three 
or more right whales are sighted in close proximity. Beginning in 2020, 
the NMFS Greater Atlantic Region modified the DMA program to include 
acoustically triggered Slow Zones. Once the trigger is met, NMFS 
establishes a boundary around the whales for 15 days and encourages 
vessels either to avoid the area or transit through at speeds less than 
10 knots (5.1 m/s). DMAs/Slow Zones may be extended if whales remain in 
the area. The agency alerts mariners to DMA and Slow Zone declarations 
through website postings, emails to lists of interested parties, U.S. 
Coast Guard Local Notices to Mariners, and U.S. Coast Guard Broadcast 
Notices to Mariners.

Need for Additional Action

    In January 2021, NMFS released an assessment evaluating the 
effectiveness of the North Atlantic right whale speed rule and 
associated voluntary DMA program (NMFS 2020) and invited the public to 
submit comments. The review found that the speed rule had made progress 
in reducing vessel strike risk to right whales but that additional 
action is warranted to further reduce the threat of vessel collisions. 
While it is not possible to establish a direct causal link between 
speed reduction efforts and the relative decline in observed right 
whale mortality and serious injury events following implementation of 
the speed rule, the preponderance of evidence suggests speed 
reductions, as implemented, have helped. NMFS' data on documented 
vessel strike events continues to affirm the role of high vessel speeds 
(> 10 knots (5.1 m/s)) in lethal collision events and supports existing 
studies implicating speed as a factor in lethal strikes events. NMFS 
has documented five right whale vessel strike cases in U.S. waters that 
resulted in non-serious injuries for which vessel speed is known. Only 
one of the five vessels involved was transiting in excess of 10 knots 
(5.1 m/s) at the time of the collision. In contrast, of the nine 
documented lethal right whale vessel collisions in U.S. waters since 
1990 for which vessel speed is known, eight involved vessels transiting 
in excess of 10 knots (5.1 m/s).
    Since the speed rule first went into effect, NMFS has documented 12 
right whale mortality and serious injury events involving vessel 
collisions in U.S. waters, along with an additional five mortality and 
serious injury events involving unknown whale species, possibly right 
whales. These figures likely underestimate the total number of lethal 
right whale vessel strikes in U.S. waters. Strikes occurring farther 
offshore and/or involving large ocean-going vessels are likely 
underreported in the data because most large ships are not able to 
detect interactions with large whales, and whales that die well 
offshore are less likely to be detected overall. Based on estimates of 
total right whale deaths, documented mortalities from all sources 
represent approximately one-third of actual annual right whale 
mortality range-wide (Pace et al. 2021). Thus, in addition to the 
observed events, NMFS recognizes that additional lethal vessel strike 
events likely went undetected in U.S. waters.
    A detailed examination of documented right whale vessel strike 
events in the U.S. further reveals the following:
    (1) Vessels less than 65 ft (19.8 m) in length accounted for five 
of the 12 documented lethal strike events in U.S. waters since 2008, 
demonstrating the significant risk this unregulated vessel size class 
can present to right whales.
    (2) Vessel strikes continue to occur all along the U.S. coast from 
the Gulf of Maine to the Florida coast. There is no indication that 
strike events only occur in ``hot spots'' or limited spatial/seasonal 
areas.
    (3) Strikes occur both inside and outside active SMAs, but in many 
cases, the location of the strike event remains unknown. Four of the 
five collision events involving vessels less than 65 ft (19.8 m) in 
length occurred inside active SMAs, although the vessels involved were 
not subject to mandatory speed restrictions due to their size.
    (4) Of the six lethal vessel strike cases documented in U.S. waters 
and involving right whales since 1999 where vessel speed is known, only 
one involved a vessel transiting at under 10 knots (5.1 m/s) (~9 knots 
(4.6 m/s)), although in most cases, we lack vessel speed data 
associated with collision events.
    (5) Females, calves, and juveniles are disproportionately 
represented in the vessel strike data. This is concerning given the 
paucity of reproductively active females remaining in the population 
and their critical role in stabilizing the population decline.
    (6) Non-lethal vessel collisions with right whales continue to 
occur. NMFS' best estimates indicate that vessel strikes (in U.S. 
waters or first seen in U.S. waters) have resulted in at least 26 non-
serious right whale injuries since 2008, although these data do not 
account for the possibility of blunt force trauma injuries, which are 
not usually visibly detectable and make accurate

[[Page 46925]]

assessments of strike injuries challenging.
    Despite NMFS' best efforts, the current speed rule and other vessel 
strike mitigation efforts are insufficient to reduce the level of 
lethal right whale vessel strikes to sustainable levels in U.S. waters. 
NMFS has determined that additional action is needed to address gaps in 
current management programs and better tailor mitigation efforts. In 
evaluating potential changes to the current speed rule NMFS considered 
up-to-date strike risk modeling, data on right whale strike events, 
species distribution, and vessel traffic characteristics in right whale 
habitat, and the extensive and informative comments received in 
response to the 2020 speed rule assessment.

Summary of Proposed Changes

    NMFS proposes changes to the existing North Atlantic right whale 
vessel speed regulations. The proposed measures detailed below seek to 
reduce the risk of mortality and serious injury from vessel strike 
events in U.S. waters and include the following:
    (1) Changes to the spatial boundaries and timing of mandatory SMAs 
to better address areas and times where vessel strike risk is high;
    (2) Inclusion of most vessels greater than or equal to 35 ft (10.7 
m) and less than 65 ft (19.8 m) in length in the vessel size class 
subject to the speed restriction;
    (3) Implementation of a Dynamic Speed Zone (DSZ) framework to 
implement mandatory speed restrictions when whales are known to be 
present outside active SMAs; and
    (4) Updates to the speed rule's safety deviation provision.

Modification of Seasonal Speed Zones (Currently Referred to as Seasonal 
Management Areas)

    Since implementation of the speed rule in 2008, the distribution of 
right whales has shifted, resulting in a misalignment between areas of 
high vessel strike risk and current SMA spatial and temporal bounds. 
Improved data on vessel traffic and right whale distribution/habitat 
use further highlight this discrepancy and the need to adjust SMA 
boundaries to better address the risk of collisions. For example, after 
2010, right whales began to frequent the region south of Martha's 
Vineyard and Nantucket, MA, and are now regularly observed in large 
aggregations foraging in the area (Leiter et al. 2017). Prior to this 
period, that region, while part of right whale habitat, was not 
identified as an important foraging area. In 2021 alone, 67 voluntary 
DMAs and Slow Zones were declared (28 of which were off Martha's 
Vineyard and Nantucket), demonstrating the ongoing spatial and temporal 
mismatch between whale aggregations and vessel strike protections.
    The goal for vessel speed regulation remains unchanged--to reduce 
the likelihood of right whale serious injuries and mortalities from 
vessel collisions. To maximize the reduction of vessel strike risk, 
NMFS developed proposed modifications to the SMAs using a coast-wide 
vessel strike mortality risk model, North Atlantic right whale visual 
sighting (NARWC 2021) and acoustic detection (NEFSC 2022) data, recent 
vessel traffic Automatic Identification System (AIS) data, and 
information on other relevant planned ocean activities, including 
offshore wind development.
    Additional factors were considered when developing proposed SMA 
spatial boundaries and timing to optimize effective right whale 
protection, including minimizing impacts on the regulated community:
    (1) NMFS sought to provide robust protection for right whales over 
a 10 to 15 year time horizon, and design built-in adaptivity to climate 
change and other factors to ensure that the speed rule remains 
resilient to shifts in right whale distribution and habitat use over 
time. This timeframe also provides a stable and predictable long-term 
regulatory structure for the maritime community.
    (2) NMFS aimed to identify the smallest spatial and temporal 
footprint possible for speed restricted areas to minimize the extent of 
regulatory action while achieving necessary conservation goals. This 
assumes a framework will be in place to implement mandatory speed 
restrictions dynamically to address right whales outside the proposed 
SMAs (see Mandatory Dynamic Speed Zones).
    (3) Changes to speed regulation areas/boundaries focused on 
reducing vessel traffic operating at speeds in excess of 10 knots (5.1 
m/s), since high transit speed is implicated in strike events, and we 
have the ability to modify this aspect of vessel operation in right 
whale habitats.

Description of the Vessel Strike Mortality Risk Model

    NMFS evaluated the risk of right whales being struck and killed by 
vessels in U.S. waters along the East Coast using an encounter risk 
model (Garrison et al. 2022). This model simulates the likelihood of a 
fatal vessel strike based on six sources of information: (1) the 
spatial distribution and density of right whales; (2) the spatial 
distribution and amount of vessel traffic; (3) the likelihood that a 
whale and a particular vessel will be in close proximity; (4) the 
likelihood that a whale will be near the surface during the 
interaction; (5) the likelihood that a whale will successfully move to 
avoid the interaction; and (6) the likelihood of mortality if a 
collision occurs. A similar approach was previously applied to large 
whales on the U.S. West Coast (Rockwood et al. 2017, 2020) and right 
whales occurring off the coast of Florida (Crum et al. 2019).
    NMFS modeled the spatial distribution of right whales using a 
compilation of aerial survey data collected by the agency and many 
different external research groups. The model and approaches are 
similar to those described in Roberts et al. (2016) and Gowan and 
Ortega-Ortiz (2014) and reflect the distribution of right whales since 
2010 (Roberts et al. 2021). Environmental variables were used to 
predict the monthly changes in right whale distribution between Florida 
and the Nova Scotian shelf.
    NMFS characterized vessel traffic using data collected via 
satellite and terrestrial based AIS that transmits information on 
vessel movements, speed, and characteristics for those vessels that 
carry AIS units. For each spatial cell in the right whale distribution 
model, NMFS summarized the length of transit, time of transit, and 
average speed of each vessel from the available AIS data. These data 
were summarized monthly for 2017-2019. Generally, most vessels greater 
than or equal to 65 ft (19.8 m) in length are required to carry AIS 
transceivers. While many vessels less than 65 ft (19.8 m) in length 
also carry AIS, they are likely to be under-represented in these data, 
and therefore, the risk of interactions with right whales is under-
represented in the model.
    NMFS modeled the likelihood of a whale-vessel encounter using the 
approach described in Martin et al. (2015), where the probability of 
close encounter between a whale and a vessel within a given spatial 
cell is a function of vessel size, whale swimming speed, and vessel 
speed. Given a close encounter, the probability that a whale will be 
near the surface (in the upper 10 m (32.8 ft) of the water column) 
where it would be susceptible to a vessel strike was estimated based on 
available data on dive-surface behavior from animal-borne tags from 
different regions where whales occur (Baumgartner and Mate 2003; 
McGregor and Elizabeth 2010; Parks et al. 2011; Baumgartner et al. 
2017; Dombroski et al. 2021).

[[Page 46926]]

    It remains unclear how right whales respond to close approaches by 
vessels (<1509 ft (460 m)) and the extent to which this allows them to 
avoid being struck. Rockwood et al. (2017) and Crum et al. (2019) 
examined different ways of accounting for avoidance behaviors within 
encounter risk models. Conn and Silber (2013) indicated that encounter 
rates were higher with fast-moving vessels than expected, which may be 
consistent with successful avoidance of slower vessels by whales. NMFS' 
model included a potential avoidance behavior accounting for random 
effects of the distance at which a whale reacts, the speed the whale 
swims to escape, and the direction the whale chooses to swim. This 
approach accounts for the increased likelihood that a whale will escape 
a slower moving vessel and includes the large amount of uncertainty in 
whale behavioral response to approaching vessels.
    In this framework, if a collision between a whale and a vessel 
occurs, the likelihood that the collision will be fatal is a function 
of vessel speed. NMFS applied the model of Conn and Silber (2013) to 
evaluate this probability. It should be noted that the data in this 
model are primarily from larger vessels, so it may be less appropriate 
for some of the small vessels included in the current analysis.

Application of the Vessel Strike Mortality Risk Model

    We used the mortality risk model (Garrison et al. 2022) to evaluate 
areas and times with the highest risk of vessel strike mortalities for 
right whales. Areas of highest risk are primarily associated with 
places where there is both a high density of vessel traffic and high 
density of right whales. In U.S. waters, these areas correspond 
generally to the Atlantic East Coast region, particularly between late 
fall and early spring (November through April). The highest risk areas 
occurred in the Mid-Atlantic between Cape Hatteras, North Carolina, and 
New York, and in relatively shallow waters over the continental shelf. 
High-density vessel traffic areas in approaches to major commercial 
ports pose the greatest risk of vessel strike mortalities. While 
vessels less than 65 ft (19.8 m) in length are under-represented in the 
AIS data, the spatial distribution of the risk of interactions with 
these vessels were also examined. In general, the risk of interactions 
with vessels less than 65 ft (19.8 m) in length was higher close to 
shore. NMFS examined the monthly spatial distribution of vessel strike 
risk to identify regions and times where slowing vessel traffic to 
speeds less than 10 knots (5.1 m/s) would have the greatest impact on 
reducing the overall risk of vessel strike mortalities for right 
whales.
    Once these spatio-temporal areas were identified, NMFS compared 
them with additional opportunistic and survey-based right whale 
sightings information, including demographics, acoustic detections of 
right whale presence, and additional information, where available, on 
possible future activities that might impact vessel traffic, including 
proposed and leased wind energy sites and U.S. Coast Guard proposed 
vessel safety fairways (85 FR 37034, June 19, 2020). It is important to 
note that the risk model is not informed by right whale sightings prior 
to 2010, opportunistic sightings, or acoustic detections. Additionally, 
as discussed above, vessel traffic from boats less than 65 ft (19.8 m) 
in length are under-represented in the model. Comparing these 
additional data with areas identified by the risk model informed 
optimal revised SMA boundaries based on the totality of information 
available.
    NMFS then used the risk model to simulate the maximum overall 
reduction in risk of lethal right whale strikes that could be achieved 
with the revised SMA boundaries. The revised boundaries were identified 
based on evaluation of those areas and times with the greatest chance 
of reducing lethal strikes to right whales. For the simulation, we 
artificially set the speed of transits within the revised SMA time-
space boundary that had an average speed greater than 10 knots (5.1 m/
s) to the 10-knot (5.1 m/s) speed that would be required. We then re-
calculated the total risk of vessel strike mortality for this simulated 
dataset and compared to the status quo, thereby providing an estimate 
of the lethal strike risk reduction, in time and space, should the SMA 
boundaries be revised to be the expanded SSZs.
    Based on this analysis of the proposed SMA boundaries and the 
additional risk reduction expected to accrue from the use of mandatory 
DSZs (see Mandatory Dynamic Speed Zones), NMFS anticipates the proposed 
revisions would address over 90% percent of the risk reduction that can 
be achieved by reducing vessel speeds to 10 knots (5.1 m/s), relative 
to the status quo. While the risk model underestimates the strike risk 
associated with traffic from vessels greater than 35 ft (10.7 m) to 
less than 65 ft (19.8 m) in length, given the expected coastal 
distribution of this traffic based on available data, we anticipate 
this component of strike risk will be sufficiently accounted for by the 
revised SMA boundaries/timing.

Proposed Boundaries and Effective Periods for Seasonal Speed Zones

    NMFS proposes changes to the current boundaries and effective 
periods of the areas seasonally subject to the 10-knot (5.1 m/s) speed 
restriction along the U.S. East Coast to better address the ongoing 
risk of right whale mortality and serious injury from vessel collisions 
(Figure 1). To more accurately describe them, we will refer to the 
areas as Seasonal Speed Zones (SSZs) (rather than Seasonal Management 
Areas or SMAs). The new SSZs include substantial spatial and temporal 
changes in the Northeast and Mid-Atlantic regions, and more modest 
changes in the Southeast region. The proposed SSZs with effective dates 
each year are summarized as follows with geographic coordinates 
provided in the proposed regulatory text:

(1) Atlantic Zone (November 1-May 30)
(2) Great South Channel Zone (April 1-June 30)
(3) North Carolina Zone (November 1-April 30)
(4) South Carolina Zone (November 1-April 15)
(5) Southeast Zone (November 15-April 15)

    NMFS proposes no active SSZs between July and October, and only the 
Great South Channel Zone would be active during the month of June. This 
is consistent with data showing fewer right whales present in U.S. 
waters during this time period. Proposed SSZs were developed with the 
understanding that DSZs would be used to implement mandatory speed 
restrictions when appropriate outside of active SSZs. NMFS anticipates 
that the combination of SSZs and DSZs will provide the spatial and 
temporal coverage necessary to significantly reduce the risk of lethal 
strike events attributable to vessel traffic transiting in excess of 10 
knots (5.1 m/s).

Regulation of Most Vessels Greater Than or Equal to 35 ft (10.7 m) in 
Length

    The existing North Atlantic right whale vessel speed rule (50 CFR 
224.105) does not address the threat of mortalities and serious 
injuries from strike events involving vessels less than 65 ft (19.8 m) 
in length. Recent vessel strike events have highlighted the lethality 
of collisions involving vessel

[[Page 46928]]

sizes not subject to the existing speed rule. Since 2020 alone, four 
right whale vessel strikes in U.S. waters resulted in mortalities and 
serious injuries: (1) a calf was seriously injured off Florida/Georgia 
in January 2020; (2) a calf was killed off New Jersey in June 2020; (3) 
a calf was killed off Florida in February 2021; and (4) its mother was 
seriously injured by the same vessel. For three of the four events, the 
vessels involved in the collisions were known to be between 35 (10.7 m) 
and 65 ft (19.8 m) in length and traveling in excess of 20 knots (10.3 
m/s) at the time.
    Since 2005, operators of vessels less than 65 ft (19.8 m) in length 
have reported eight right whale vessel strikes in U.S. waters. Six 
resulted in right whale serious injuries or mortalities. The reporting 
vessels ranged in length from 17-54 ft (5.2-16.5 m), with vessels 
involved in mortality and serious injury events ranging in size from 
42-54 ft (12.8-16.5 m) in overall length. The vessel speeds at the time 
of the strike events ranged from less than 5 knots (2.6 m/s) to 
approximately 28 knots (14.4 m/s) (Henry et al. 2011, 2021; Wiley et 
al. 2016). Of the eight strike events involving vessels less than 65 ft 
(19.8 m) since 2005, five (including the recent strikes involving a 
mother/calf pair) occurred within active SMAs where most vessels 65 ft 
(19.8 m) and over are required to travel at 10 knots (5.1 m/s) or less.
    In seven of the eight events involving vessels less than 65 ft 
(19.8 m) in length, mariners reported no sighting of the whales prior 
to impact with the vessel. Vessel strikes can occur even when 
circumstances are seemingly optimal for avoidance as illustrated by two 
right whale vessel strikes involving research vessels less than 65 ft 
(19.8 m) in length with trained observers aboard that occurred in Cape 
Cod Bay during daylight hours (Wiley et al. 2016). These events 
demonstrate that mariner experience and vigilance alone can be 
insufficient to protect against vessel collisions.
    Furthermore, since 2009, operators of vessels less than 65 ft (19.8 
m) in length have reported an additional six vessel collisions 
(including five serious injuries) with undetermined large whale species 
in U.S. waters that may have involved right whales based on the 
location and timing of the events (Henry et al. 2017). Documented 
vessel strike deaths of Southern right whales (Eubalaena australis) off 
Australia and South Africa involving a 34-ft (10.4-m) vessel and 44-ft 
(13.4-m) vessel respectively, further demonstrate the lethal risk 
vessels less than 65 ft (19.8 m) in length can pose to right whale 
species more broadly (Peel et al. 2016; Vermeulen et al. 2021).
    Other jurisdictions have instituted speed restrictions for vessels 
less than 65 ft (19.8 m) in length to mitigate vessel strike risk for 
North Atlantic right whales. Following a series of right whale vessel 
strike events, Canada expanded the length of vessels covered by dynamic 
mandatory 10-knot (5.1 m/s) speed restrictions in the Gulf of St. 
Lawrence in 2019 to include vessels 13 m (42.7 ft) or greater in 
length. Also in 2019, the state of Massachusetts introduced regulations 
restricting the speed of most vessels less than 65 ft (19.8 m) in 
length to 10 knots (5.1 m/s) or less when transiting through waters 
within, and to the north of, Cape Cod Bay during the months of March 
and April each year to provide protection for foraging right whales 
following vessel strike events in the Bay (322 CMR 12.05). 
Massachusetts has received no reports of strikes involving vessels less 
than 65 ft (19.8 m) in length, nor reports of safety concerns from 
mariners in this area since implementation of the regulation. The State 
has extended these vessel speed restrictions into the month of May 
during years when right whales remained in the Bay.
    Collisions with vessels less than 65 ft (19.8 m) in length pose a 
danger to both the whale and vessel occupants. There are numerous cases 
from around the world of vessels sustaining significant damage, and 
even sinking, following collisions with whales (Ritter 2012; Peel et 
al. 2018). For example, two vessel-whale collisions that occurred in 
March 2009 and February 2021 resulted in vessel damage significant 
enough to require passenger rescue by the U.S. Coast Guard. Sailing 
vessels can be at particular risk of substantial damage due to their 
deliberately light construction (Ritter 2012) even though most transit 
at speeds at or under 10 knots (5.1 m/s). Moreover, collisions with 
vessels less than 65 ft (19.8 m) in length with whales have resulted in 
injuries to vessel occupants (NMFS unpublished data).
    For the reasons detailed above, NMFS proposes to expand the size 
class of vessels currently subject to speed restrictions to include 
most vessels greater than or equal to 35 ft (10.7 m) to less than 65 ft 
(19.8 m) in overall length. Most vessels within this size class are not 
subject to U.S. Coast Guard AIS carriage requirements, but based on 
limited available AIS data and U.S. Coast Guard vessel registration 
data (USCG 2021), this change may affect up to 8,500-10,000 vessels 
(albeit to varying degrees). Best estimates indicate that approximately 
80 percent of these vessels are larger recreational boats, with 
commercial fishing (7 percent) and passenger vessels (6 percent) the 
next most common types. The remaining vessel types include work boats, 
pilot boats, tug and tow vessels, and other commercial vessels. The 
total number of affected vessels is likely substantially overestimated, 
particularly for recreational boats, since available data lack detail 
about where, when, and how frequently a boat operates within areas 
subject to speed regulation.

Mandatory Dynamic Speed Zones

    Though NMFS' 2006 proposed speed rule included the concept of 
mandatory DMA speed restrictions that fall outside active SMAs (71 FR 
36299, June 26, 2006), the 2008 final speed rule did not. Instead, the 
agency announced it would implement a voluntary DMA program creating 
short-term ``dynamic'' areas within which NMFS sought voluntary 
compliance with restricted speeds based on sightings of right whale 
aggregations. In 2020, NMFS modified the DMA program to include 
acoustically triggered Right Whale Slow Zones in the NMFS Greater 
Atlantic Region (Maine to Virginia), given the increasing availability 
of near-real time acoustic detectors able to accurately identify right 
whale presence. If followed, dynamic speed reduction areas provide 
vessel strike risk reduction to aggregations of right whales or areas 
with persistent right whale presence outside active SMAs in near-real 
time. The program was intended to provide protection for right whales 
in areas/times not covered by SMAs. As discussed above, shifts in right 
whale distribution and habitat use since the current SMAs were 
established in 2008 have resulted in a substantial number of DMA and 
Slow Zone declarations.
    NMFS 2008 speed rule stated the agency would ``monitor voluntary 
compliance'' and if cooperation was not satisfactory would ``consider 
making them mandatory, through a subsequent rulemaking'' (73 FR 60173, 
October 10, 2008). Despite NMFS' best efforts to reach out to vessel 
operators about dynamic speed reduction areas and educate the maritime 
community about the need for right whale vessel strike mitigation, 
NMFS' speed rule assessment determined that vessel cooperation levels 
are low, and therefore, the reduction in risk provided by the voluntary 
DMAs is minimal (NMFS 2020).
    As discussed above, the proposed SSZs boundaries/timing are 
designed to address most vessel strike risk attributable to vessels 
transiting in excess of 10 knots (5.1 m/s). Based on

[[Page 46929]]

an evaluation of recent voluntary DMAs and acoustically triggered Slow 
Zones, 54 of the 67 DMAs/Slow Zones triggered during 2021 (80.6 
percent) would fall within the proposed SSZs. In other words, only 13 
(19.4 percent) of 2021 DMAs/Slow Zones would have been triggered if the 
proposed SSZ boundaries were in effect. This indicates that the 
existing misalignment between the current SMA boundaries and elevated 
risk areas is substantially, but not wholly, captured by the proposed 
SSZs. Thus, even after adjusting the geographic boundaries and timing 
of the static SSZs to more accurately reflect the best available data 
on right whales and vessel strike risk, there is still a role for 
dynamic speed restrictions to protect other areas where right whales 
occur less predictably.
    In examining the totality of information available to inform 
changes to the location and timing of SSZ boundaries, it became clear 
that for some areas and seasons, static speed management may not be 
sufficient as a sole strategy to reduce vessel strike risk. This is 
primarily the case in areas where right whale presence is less 
predictable or more ephemeral and/or where elevated strike risk is more 
moderate.
    Static speed restrictions best serve areas with reliable right 
whale presence and elevated strike risk. For example, right whales 
reliably occur within the South Atlantic Bight calving ground each and 
every season (November through April). The total number of individuals 
present will vary from year to year (Krzystan et al. 2018), but this 
calving, and likely mating, habitat is an essential area for right 
whale reproduction and is designated (81 FR 4837, January 27, 2016) as 
critical habitat under the ESA. The consistency of right whale presence 
(especially vulnerable mothers/calf pairs) combined with high levels of 
vessel traffic along the Southeast coast are the primary reasons vessel 
strike risk in this region is best managed via a static SSZ.
    In other times/areas, however, right whale presence may be less 
predictable and/or elevated vessel strike risk more moderate. For 
example, during late fall and winter, right whales have been documented 
over many years in the central Gulf of Maine, frequently engaged in 
foraging. Right whales have been visually or acoustically detected in 
this area during most, but not every fall/winter season, and vessel 
strike risk is lower in this area, relative to other parts of the U.S. 
East Coast, due to lower levels of vessel traffic transiting at high 
speeds. Vessel strike risk modeling indicates a benefit to right whales 
from vessel speed restriction in this area but to a lesser degree than 
other places/times. With adequate seasonal monitoring for right whale 
presence, a dynamic area speed restriction is ideally positioned to 
provide vessel strike protection in this area when and where it will be 
most beneficial to right whale conservation.
    To address elevated vessel strike risk in areas outside SSZs, NMFS 
is proposing to implement a mandatory DSZ framework to replace the 
current voluntary DMA/Slow Zone program. Under this proposed framework 
protocol, as described below, a mandatory DSZ would be created for an 
area outside an active SSZ, within U.S. waters from Maine to Florida, 
based on (1) a confirmed visual sighting of a right whale aggregation 
(three or more whales in close proximity) or a confirmed right whale 
acoustic detection (since it is not possible to quantify the number of 
individual whales present) and (2) NMFS determination that the area to 
be designated as a DSZ has a greater than 50 percent likelihood of 
right whale presence during a minimum effective period of 10 days 
(periods shorter than this may present practical challenges for 
implementation).
    Existing protocols for the current voluntary DMA/Slow Zone program 
are proposed as a minimum trigger threshold to inform a new DSZ. Under 
these protocols, NMFS establishes voluntary 15-day DMAs when three or 
more right whales are sighted within close proximity. Depending on the 
size and geographic spread of the right whale aggregation, the spatial 
extent of the DMA is determined based on a local density method as 
outlined in Clapham and Pace (2001), with most zones approximately 400 
square nautical miles (sq nm; 1,372 sq kilometers (sq km)). NMFS 
declares voluntary Slow Zones in the NMFS Greater Atlantic Region when 
a right whale acoustic detection is confirmed. Acoustically triggered 
Slow Zones extend approximately 20 nm from the detection source and 
remain effective for 15 days. DMAs/Slow Zones may be extended if 
additional sightings or acoustic detections meeting the thresholds 
above are detected within the latter half of the 15 day effective 
period. Once the initial detection trigger has been met, NMFS would 
then determine whether the potential DSZ has a greater than 50 percent 
likelihood that right whales would continue to be present within the 
zone (not to exceed 2,500 sq nm (8,575 sq km) commensurate with the 
size of the aggregation for visual detections or 400 sq nm (1,372 sq 
km) for acoustic detections). As with the current voluntary DMA/Slow 
Zone program, DSZs may be extended if additional sightings or acoustic 
detections meeting the minimum thresholds occur within the effective 
period.
    Drawing upon the agency's long-time expertise implementing 
voluntary dynamic areas over the last 13 years, NMFS' process for 
determining and implementing DSZs would follow an objective, rigorous 
and replicable protocol, informed by inputs such as the number of right 
whales detected, the dispersion of the aggregation, and whale behavior 
(if known). Furthermore, NMFS would provide details of the DSZ 
determination when providing public notice of a DSZ designation. 
Ensuring that DSZs meet a minimum trigger threshold and a greater than 
50 percent likelihood of continued right whale presence standard would 
provide confidence that these zones will effectively achieve the goal 
of providing targeted protection to right whales (in areas not 
protected by static zones) from elevated vessel strike risk while 
avoiding unnecessary regulation of vessel speed.
    The boundaries and timing of temporary DSZs for right whales are by 
their very nature uncertain until the conditions that trigger one are 
present. Once those conditions are determined to be in place, however, 
the need for those DSZs to be effective to protect right whales is 
immediate. Implementing DSZs through publication of Federal Register 
notices does not allow for timely implementation of a DSZ and could 
result in unnecessary avoidable risk of both vessel strikes of right 
whales and potentially mariner safety. The time normally required to 
file and publish a DSZ's boundaries and effective period in the Federal 
Register would delay implementation and diminish the value and 
effectiveness. Thus, this proposed rule allows NMFS to implement timely 
DSZs without prior publication in the Federal Register as follows.
    When NMFS determines that the criteria for establishing a DSZ, or 
DSZ extension, have been met, NMFS will announce notice of the DSZ or 
DSZ extension through publication on the agency's website, via U.S. 
Coast Guard Notices to Mariners, NOAA Weather Radio announcements, and 
through other practicable appropriate means, as well as by Notice in 
the Federal Register as soon as practicable. NMFS requests public 
comment on other effective means for notifying the public, including 
social media, smartphone apps, email notifications and text alerts to 
which mariners, harbormasters, port officials, pilots, and the public 
can subscribe. As stated earlier, the proposed SSZs will accrue a net

[[Page 46930]]

expansion of vessel strike risk coverage compared to the areas in the 
current speed regulation, including many areas/times where voluntary 
DMAs and Slow Zones have been common. NMFS anticipates that under the 
proposed DSZs framework, the prevalence of these zones will be less 
frequent, given the more rigorous coverage provided by the proposed SSZ 
boundaries. Additionally, since 2008, nearly all voluntary DMAs and 
Slow Zones were triggered on the continental shelf, with 93 percent 
occurring in the NMFS Greater Atlantic Region (Maine to Virginia). 
Accordingly, NMFS anticipates that proposed DSZs would continue to be 
most common north of North Carolina and within coastal and shelf 
waters.
    NMFS requests public comment on the proposed DSZ framework for the 
proposed mandatory DSZ program. NMFS particularly invites comment on: 
(1) the geographic areas that should be subject to mandatory DSZs; (2) 
the appropriate design of trigger thresholds using confirmed right 
whale acoustic and/or visual detections as well as the appropriate 
methodology for determining spatial extent as it relates to the greater 
than 50 percent likelihood standard for presence; and (3) the forms of 
notice mariners would find most practicable for receiving timely 
declarations of new DSZs.
    The use of dynamic strategies to manage vessel speed for right 
whale protection is already customary, and employed in U.S. waters. The 
State of Massachusetts dynamically extends the effective period of its 
small vessel speed restrictions in Cape Cod Bay if the continued 
presence of right whales is detected in the Bay, as the State did in 
2021 (Massachusetts Division of Marine Fisheries 2021). NMFS' long-time 
(since 1997) approach regulations also require mariners to modify their 
vessel operations (including speed and/or direction of travel) in real-
time if they encounter right whales while transiting. Mariners must 
remain 500 yards (457.2 m) away from right whales unless compliance 
would create a serious threat to vessel safety. This strategy is also 
used in Canadian waters. Since 2018, Canada has implemented a seasonal 
system of mandatory dynamic right whale speed restrictions within the 
Gulf of St Lawrence shipping lanes and during the summer, creates a 
dynamic Restricted Area to further protect foraging aggregations, as 
needed, based on right whale detections, and announced through 
Transport Canada Ship Safety Bulletins (Transport Canada 2021a, 2021b).
    Year-round visual and acoustic monitoring of right whale habitat 
outside proposed active SSZs will be essential to the effectiveness of 
the proposed mandatory DSZs. NMFS' coast-wide vessel strike mortality 
risk model indicates where and when elevated strike risk is present, 
and can serve as a resource for identifying monitoring needs (Garrison 
et al. 2022). In 2019, NMFS convened an expert working group to provide 
recommendations to enhance right whale monitoring along the U.S. East 
Coast. The effort culminated in a detailed report that included 
recommendations for monitoring right whale distribution (Oleson et al. 
2020). NMFS continues to review recommendations from the monitoring 
report and is taking monitoring needs for proposed mandatory DSZs into 
consideration as it works with external partners to optimize right 
whale monitoring efforts.

Updates to Safety Deviation Provisions

    NMFS established a safety deviation provision within the 2008 speed 
rule (50 CFR 224.105) to accommodate situations where transit at speeds 
of 10 knots (5.1 m/s) or less during severe conditions would threaten 
human or navigational safety. Following a review of vessel transit data 
and compliance information as part of the speed rule assessment (NMFS 
2020), NMFS investigated options to better understand the extent of 
safety impacts from the speed rule and to monitor use of the safety 
deviation provision. Current regulations lack a mechanism by which the 
agency can efficiently identify which vessels are employing the safety 
deviation and when and where use of the safety deviation may be common. 
Existing information collection protocols lack sufficient detail to 
determine the circumstances surrounding a deviation and to assess 
situations where a vessel may lack reasonable grounds to employ the 
safety deviation. NMFS further recognizes that the current safety 
deviation language lacks recognition of emergency situations that do 
not involve a maneuverability issue, when a vessel may have immediate 
cause to exceed the 10-knot (5.1 m/s) speed restriction due to a 
medical or other emergency involving the health or life of a vessel 
passenger.
    The proposed inclusion of vessels less than 65 ft (19.8 m) in 
length within the vessel size class subject to speed regulation 
presents a new safety issue unique to smaller and lighter boats. During 
severe weather conditions, vessels less than 65 ft (19.8 m) in length 
may face maneuverability and associated safety issues. While some 
vessel operators can easily avoid such conditions, others may need to 
be out on the water during severe weather events to provide essential 
maritime services, or as a part of other work obligations.
    To address the issues stated above, NMFS proposes to retain the 
current safety deviation provision with several changes:
    (1) Expansion of the safety deviation provision to include 
emergency situations that present a threat to the health, safety, or 
life of a person;
    (2) Inclusion of a new provision, applicable only to vessels less 
than 65 ft (19.8 m) in length, which allows such vessels to transit at 
speeds greater than 10 knots (5.1 m/s) within areas where a National 
Weather Service Gale Warning, or other National Weather Service Warning 
(e.g., Storm Warning, Hurricane Warning) for wind speeds exceeding 
those that trigger a Gale Warning is in effect. No reporting of these 
speed deviations would be required; and
    (3) Modification of the safety deviation reporting protocols to 
eliminate the vessel logbook entry requirement in favor of a new 
requirement for vessels to submit an online report to NMFS within 48 
hours of employing a safety deviation detailing the circumstances and 
need for the deviation.
    The proposed regulations would require a vessel operator to submit, 
via a NMFS website, the same information currently contained in the 
logbook entry along with new information relevant to the deviation 
event, including:
    (1) Vessel name, length overall, draft (at the time of the 
deviation) and where applicable, the vessel IMO number and Maritime 
Mobile Service Identity (MMSI) number;
    (2) Reason for the deviation: (a) maneuverability constraints, or 
(b) emergency;
    (3) Date, time, latitude, and longitude where deviation began;
    (4) Date, time, latitude, and longitude where deviation ended;
    (5) Speed or average speed at which the vessel transited during the 
deviation;
    (6) Wind speed and direction at the time of the deviation;
    (7) Information on water current speed and direction at the time of 
the deviation, including measurements from the vessel acoustic doppler 
current profiler (ADCP), if the vessel is equipment with this device;
    (8) If the vessel was operating within a restricted/dredged 
channel, indicate

[[Page 46931]]

whether one-way or two-way vessel traffic was present within the 
channel at the time the deviation was employed;
    (9) The vessel master, and, if the vessel was under pilotage, the 
pilot, must attest to the accuracy of the information contained within 
the Report. If the vessel was under pilotage, indicate the name of the 
harbor pilot;
    (10) Opportunity to briefly provide additional narrative (300 word 
limit), if desired, to explain the circumstances of a safety deviation.
    NMFS specifically invites comment on the proposed reporting 
requirements, including comments on whether a web-based reporting 
mechanism is practicable for mariners, who should be responsible for 
completing and attesting to reports (for example, whether pilots should 
be responsible for completing and attesting to reports when a vessel is 
under pilotage), and on requiring more robust logbook recordkeeping in 
lieu of the new reporting requirements proposed herein.
    NMFS recognizes that under certain conditions, vessel 
maneuverability and/or navigational safety may be hampered by 
transiting at reduced speeds, especially within port entrance areas. 
NMFS' current and proposed speed regulations acknowledge this through 
the safety deviation provision that is available when vessel 
maneuverability is compromised by the speed restriction. Given the 
totality of changes proposed herein, particularly the expanded size 
class of vessels subject to regulation, most pilot vessels operating 
within port entrance areas will likely be newly subject to speed 
regulation. NMFS solicits comments on options for alternative speed 
reduction programs specifically within port entrance areas that best 
maintain navigational safety while providing comparable vessel strike 
protections to right whales. Alternative programs would be conducted 
and resourced by external partners, include comprehensive monitoring of 
right whale presence, and provide a level of vessel strike risk 
reduction equivalent to that achieved through the measures described in 
this rule.

Additional Enforcement Clarifications

    NMFS is also clarifying that the prohibitions set forth in Section 
9(g) of the ESA would apply to the speed restrictions and reporting 
requirements set forth in this rule. Additionally, consistent with 
Section 10(g) of the ESA, NMFS clarifies that any person claiming the 
benefit of an exception to this rule has the burden of proving that the 
exception applies. Sections 9(g) and 10(g) of the ESA would apply 
irrespective of these changes. However, NMFS believes it is appropriate 
to provide additional notice to the public of how these provisions 
would apply under the proposed rule. This clarification would also 
provide consistency with other rules designed to protect North Atlantic 
right whales. With limited exception, regulations at 50 CFR 224.103(c) 
currently provide that it is unlawful ``to commit, attempt to commit, 
to solicit another to commit, or cause to be committed'' an approach 
within 500 yard of a North Atlantic right whale. The approach 
regulation also makes clear that a person claiming the applicability of 
an exception has the burden of proving that the exception applies.

Vessel Exemptions

    The proposed rule includes one change to the exemptions for certain 
vessels at 50 CFR 224.105(a). Currently the speed regulations exempt 
vessels that are owned or operated by, or under contract to, the 
Federal Government, and that exemption extends to foreign sovereign 
vessels when they are engaging in joint exercises with the U.S. 
Department of the Navy. This proposed rule would extend the exemption 
to foreign sovereign vessels engaging in joint exercises with the U.S. 
Coast Guard. All other exemptions remain unchanged. As stated earlier, 
an exemption from the speed regulations does not affect a federal 
agency's consultation requirement under section 7 of the ESA, and 
reduced speeds may be recommended or specified as part of a section 7 
consultation to reduce the threat of vessels collisions with right 
whales. Federal action agencies should continue to monitor their 
actions to determine if reinitiation of a consultation is warranted 
based on triggers specified at 50 CFR 402.16. This proposed action, 
however, does not provide a basis for reinitiation.

Stakeholder Considerations

    NMFS designed the proposed changes to provide necessary enhanced 
protection for endangered right whales while minimizing impacts on 
human use of ocean resources for commerce and recreation. NMFS 
recognizes that vessels regularly operating at speeds in excess of 10 
knots within areas/times designated for speed restriction in this 
proposed rule will likely experience delayed transit times within these 
areas, although there will be no restrictions on when or where a vessel 
may transit.
    In addition to considering public comments from stakeholders 
regarding impacts of the proposed rule, NMFS will continue to work with 
key federal partners, including the U.S. Coast Guard, Bureau of Ocean 
Energy Management, U.S. Army Corps of Engineers, and Marine Mammal 
Commission, to ensure mariner safety and address stakeholder concerns 
regarding the proposed changes. For example, NMFS is aware of the 
nascent offshore wind energy industry and the substantial overlap of 
likely future wind energy development with the proposed Seasonal Speed 
Zones, possible Dynamic Speed Zones, and right whale habitat generally. 
The proposed changes would provide a stable regulatory landscape for 
companies as they plan future vessel-based operations for offshore 
energy construction and long-term management, while providing necessary 
protection for right whales throughout the U.S. portions of their 
habitat.
    NMFS anticipates the proposed rule will impact a larger number of 
recreational boaters and anglers than the current rule, due mostly to 
the inclusion of vessels equal to or greater than 35 ft in length. 
Recreational fishing is widely enjoyed and generates billions of 
dollars in overall economic contribution along the U.S. East Coast 
(Lovell et al. 2020). To better understand the impacts of the proposed 
rule on recreational angling, NMFS invites public comment on the degree 
to which the mandatory speed limit (for most vessels equal to or 
greater than 35 ft in length) may impact recreational angling within 
the active proposed Seasonal Speed Zones and Dynamic Speed Zones. NMFS 
anticipates that the seasonal nature of most speed restrictions will 
minimize the impacts of the proposed rule on recreational activities. 
In the Southeast and Mid-Atlantic, the proposed restrictions will be in 
effect during seasons with less recreational angler activity. In the 
greater New England area, most seasonal speed restrictions occur during 
periods of colder weather, when recreational activity is low, although 
this region is most likely to see Dynamic Speed Zones triggered during 
seasons of higher recreational activity based on right whale 
distribution data.

Other Considerations

    In addition to the proposed vessel speed measures herein, NMFS 
plans to continue an ongoing review of vessel routing measures to 
examine the effectiveness of such measures and investigate 
opportunities to further reduce the spatial and temporal overlap of 
vessels and right whales through routing measures, if warranted. 
Effective outreach to the mariner community remains an important means 
of ensuring speed regulations are understood and

[[Page 46932]]

adhered to by the regulated community. NMFS is engaged in ongoing 
research to identify effective means to communicate with this 
community.
    NMFS also recognizes the role whale avoidance technologies may one 
day play in preventing vessel collisions, and remains open to the 
future application of these technologies, if proven safe and effective. 
The use of onboard marine mammal observers is another strategy employed 
to reduce vessel strike events. For some activities and vessel types, 
the addition of marine mammal observers can provide an added mechanism 
to prevent vessel strikes in conjunction with other conservation 
measures; however, documented right whale vessel strikes involving 
vessels with trained observers demonstrate the inconsistency of this 
tool.
    While the proposed rule is designed to address lethal right whale 
vessel strike risk, NMFS anticipates ancillary benefits, including 
reduced vessel strike risk, will accrue to other marine species. 
Endangered and protected cetaceans, pinnipeds, sea turtles, and certain 
fish species inhabit the regions/seasons covered by the proposed 
action. Vessel strikes are an ongoing threat to all large whale species 
and are contributing to two ongoing Unusual Mortality Events involving 
minke (Balaenoptera acutorostrata) and humpback whales (Megaptera 
novaeangliae). Researchers have found that the majority of large whale 
vessel strike mortalities involve vessels transiting at speeds greater 
than 10 knots (Laist et al. 2001; Jensen and Silber 2004; Vanderlaan 
and Taggart 2007; Conn and Silber 2013). NMFS expects both the spatial 
and temporal expansion of SSZs and inclusion of vessels equal to or 
greater than 35 ft in length will provide additional beneficial vessel 
strike risk reduction to other large whale species.
    Numerous studies have linked reduced vessel transit speeds with a 
reduction in ocean noise (McKenna et al. 2012, 2013; Leaper et al. 
2014; Gassmann et al. 2017; MacGillivray et al. 2019; Duarte et al. 
2021). The proposed rule is expected to reduce radiated underwater 
ocean noise particularly in areas where substantial numbers of vessels 
would slow their speeds to 10 knots (5.1 m/s) or less. This change in 
speed would subsequently reduce noise disturbances, such as sound 
masking, for marine species occurring in overlapping areas/seasons. 
Additionally, for certain vessel types, the proposed rule is expected 
to result in reduced fuel use, and thus emissions, by slowing more 
vessels over a larger net spatial and temporal area compared to current 
conditions. NMFS anticipates these reductions would contribute to 
enhanced air quality, and support lower fossil fuel emissions, a 
priority for climate change mitigation, benefiting both human health 
and marine species.
    As with the current speed regulation, NMFS recognizes that vessel 
compliance and effective enforcement is critical to the effectiveness 
of the proposed rule. Overall vessel compliance with the current speed 
rule is monitored based on protocols and procedures outlined in the 
2020 vessel speed rule assessment (NMFS 2020). NMFS uses the distance 
weighted average vessel speed to identify sections of transits that 
exceed 10 knots and considers the total distance at or under 10 knots 
as the best metric of apparent compliance. NMFS has seen increasing 
levels of vessel compliance over time since the speed rule first went 
into effect in 2008.
    NOAA has already taken steps to address ongoing enforcement 
challenges and prepare for new challenges resulting from the inclusion 
of vessels equal to or greater than 35 ft in length. Specifically, the 
Office of Law Enforcement has upgraded capabilities for tracking vessel 
speed at sea, initiated research of new vessel tracking technologies, 
and started investigating land-based and aerial monitoring options. 
NMFS has also commenced staff level discussions with the U.S. Coast 
Guard regarding possible modification of current AIS carriage 
requirements to include additional vessel types and sizes. Furthermore, 
as discussed above, NMFS is proposing changes to the speed rule 
specifically designed to enhance monitoring and enforcement.
    The inclusion of vessels equal to or greater than 35 ft in length 
under the proposed rule will involve some increased enforcement costs 
since many vessels in this size class are not equipped with AIS and 
cannot be monitored in the same way as AIS-equipped vessels. Moving 
forward, NOAA believes a diversified enforcement approach is needed. 
This would involve expanding at-sea operations in appropriate 
locations, using additional technologies to monitor vessel speed, 
providing compliance assistance to the regulated community, including 
outreach, and bringing enforcement cases in appropriate circumstances.
    These enhancements to NOAA's enforcement efforts are not expected 
to substantially raise costs. NOAA intends to efficiently and 
effectively enforce the proposed rule building upon ongoing at-sea 
enforcement efforts, and we anticipate receiving continued assistance 
from enforcement partners such as the U.S. Coast Guard and State law 
enforcement agencies. The increase in potentially affected vessels 
under the proposed rule is not necessarily commensurate with an 
increase in enforcement costs. While more vessels may be subject to 
speed regulation under the proposed rule, enforcement will focus on 
those vessels posing the greatest risk to right whales. Proposed 
changes to the safety deviation reporting protocols should also 
streamline enforcement.
    NOAA brings civil administrative enforcement cases to achieve both 
specific and general deterrence. Violations of the current speed rule 
can result in significant monetary penalties, which serve as a 
deterrent to other potential violators. Outreach can also be an 
effective tool to improve compliance. This year, NOAA sent 
approximately 400 letters to vessels suspected of violating the speed 
limit to encourage compliance. NOAA is committed to continuing and 
expanding outreach efforts under the proposed rule.

Classification

    NMFS is proposing this rule pursuant to its rulemaking authority 
under MMPA section 112(a) (16 U.S.C. 1382(a)), and ESA section 11(f) 
(16 U.S.C. 1540(f)).
    A Draft Environmental Assessment for this proposed action was 
prepared and is available at https://www.fisheries.noaa.gov/national/endangered-species-conservation/reducing-vessel-strikes-north-atlantic-right-whales.
    An informal consultation under ESA section 7 is currently underway 
for this proposed action. Consultation will be completed before a final 
rule is issued.
    This proposed rule has been determined to be significant under E.O. 
12866 and NMFS has prepared a draft Regulatory Impact Review (RIR). 
NMFS estimates that approximately 15,899 vessels would be affected by 
the proposed revisions to the current speed rule at an estimated cost 
of just over $46 million per year. Affected vessels include those that 
are: (1) subject to speed regulation and (2) documented or estimated to 
transit in excess of 10 knots (5.1 m/s) within the proposed SSZs and 
potential DSZs. Of the 15,899 vessels identified, 9,220 (59 percent) 
are recreational/pleasure boats, 3,575 (22 percent) are ocean-going 
commercial ships, and 3,124 (19 percent) are commercial, industrial and 
other vessel types, although the number of affected vessels less than 
65 ft (19.8 m) is likely overestimated. The largest proportion of the 
overall estimated cost of the proposed changes is borne by ocean-going 
commercial ships (35 percent) followed by passenger vessels (26 
percent) and industrial work vessels (18 percent). NMFS invites public 
comment on potential economic, operational or safety impacts from the 
proposed changes.
    NMFS prepared an Initial Regulatory Flexibility Analysis (IRFA) as 
required by section 603 of the Regulatory Flexibility Act. The IRFA 
describes the economic impact this proposed rule, if adopted, would 
have on small entities. We anticipate a total of 2,524 small entities 
(individual vessels) would be affected by the proposed rule with an 
estimated annual cost, as a percentage of revenue, ranging from 0.06% 
to 2.09%, depending on the vessel type, with passenger and pilot 
vessels most impacted. Commercial fishing and passenger vessel entities 
make up a combined 60% of the total small entities affected by the 
rule, although as a proportion of revenue the cost of this impact is 
substantially lower for commercial fishing vessels. A full description 
of the proposed action, and the legal basis and objectives of the 
action, are discussed above and are not repeated here.

[[Page 46935]]

    The proposed action includes no day-to-day reporting requirements. 
A vessel operator only needs to submit a brief electronic report to 
NMFS if they use the safety deviation provision due to limited 
maneuverability affecting vessel safety or an emergency. Since these 
safety/emergency situations are expected to be rare, the impact on 
small entities should be minimal. No special professional skills are 
needed to submit the report other than knowledge of the vessel and the 
conditions relevant to the safety deviation.
    NMFS considered a number of alternatives in its Draft RIR and Draft 
Environmental Assessment but did not identify any significant 
alternatives which would accomplish the stated objective of this 
proposed rule. Alternatives considered included:
    (1) Alternative 1 (No Action Alternative) would maintain the status 
quo. No action would be taken and vessel traffic along the U.S. East 
Coast would continue as is under 50 CFR 224.105.
    (2) Alternative 2 would restrict the speed of most vessels greater 
than or equal to 35 ft (10.7 m) and less than 65 ft (19.8 m) in length 
to 10 knots (5.1 m/s) or less within existing SMAs.
    (3) Alternative 3 would modify the spatial and temporal boundaries 
of the existing SMAs to create newly proposed SSZs. The size class of 
vessels subject to speed regulation would remain unchanged.
    (4) Alternative 4 would restrict the speed of most vessels greater 
than or equal to 35 ft (10.7 m) and less than 65 ft (19.8 m) in length 
to 10 knots (5.1 m/s) or less within existing SMAs, and establish a 
mandatory DSZ program.
    (5) Alternative 5 (Preferred Alternative) would modify the spatial 
and temporal boundaries of the existing SMAs to create newly proposed 
SSZs, add vessels greater than or equal to 35 ft (10.7 m) and less than 
65 ft (19.8 m) in length to the vessel size class subject to speed 
regulation, and establish a mandatory DSZ program.
    The changes proposed in this action are designed to significantly 
reduce the risk of lethal vessel strike events involving right whales 
in support of broader efforts to stabilize the rapid, unsustainable 
decline in population. Maintaining the status quo (Alternative 1) would 
not result in any additional reduction in strike risk. Alternative 2 
would address strike risk from most vessels greater than or equal to 35 
ft (10.7 m) and less than 65 ft (19.8 m) in length but fails to fix the 
spatial and temporal misalignment of current SMAs, leaving right whales 
vulnerable to vessel collision in many areas. Alternative 4 partially 
addresses this issue by further extending mandatory protections through 
the DSZ framework, but given the broad spatial/temporal extent of the 
areas NMFS has identified as high risk outside the current SMAs, the 
use of a dynamic framework would be inadequate to mitigate the constant 
strike risk in certain areas/seasons, and would create a cumbersome and 
less predictable regulatory environment. Alternative 3 successfully 
addresses much of the spatial and temporal misalignment of current SMAs 
but fails to address the risk from vessels less than 65 ft (19.8 m) in 
length, which account for at least 42% of documented lethal strike 
events in U.S. waters since the speed rule was implemented in 2008. 
Only Alternative 5, (the action proposed herein) provides a high 
likelihood (>90%) of substantial reduction in lethal strike events 
involving most vessels greater than or equal to 35 ft (10.7 m) 
transiting at speeds greater than 10 knots (5.1 m/s), assuming full 
compliance with the proposed rule.
    The proposed action is not expected to have a disproportionately 
high effect on minority populations or low-income populations under 
E.O. 12898.
    The proposed action does not contain policies with federalism 
implications under E.O. 13132.
    This proposed action contains a revision to the existing 
collection-of-information authorization (OMB Control number 0648-0580) 
for this rule under the Paperwork Reduction Act (PRA). The appropriate 
PRA documents will be submitted following publication of the proposed 
rule.

    (6) Dynamic Speed Zones (DSZs):
    (i) Designation. At all times of year and in all waters along the 
U.S. Atlantic seaboard, including the entire U.S. Exclusive Economic 
Zone, except SSZs specified in paragraphs (a)(1) through (5) of this 
section, a DSZ will be designated upon a determination by NMFS that 
there exists:
    (A) At a minimum, a confirmed visual sighting of three or more 
North Atlantic right whales within close proximity or confirmed 
acoustic detection of a North Atlantic right whale; and
    (B) A greater than 50 percent likelihood that North Atlantic right 
whales will remain within the designated DSZ while it is in effect.
    (C) A DSZ shall have a minimum effective period of 10 days and 
shall not exceed 2500 sq nm (8575 sq km) in size for visually triggered 
DSZs and 400 sq nm (1372 sq km) for acoustically triggered DSZs. The 
DSZ may be extended for additional periods provided that NMFS makes the 
required determinations for designating a DSZ specified in this 
paragraph.
    (ii) Notice of DSZ. Notice of a DSZ or DSZ extension will be posted 
at https://www.fisheries.noaa.gov and disseminated via U.S. Coast Guard 
Notice to Mariners, NOAA Weather Radio announcements, and through other 
practicable appropriate means, as well as by Notice in the Federal 
Register as soon as practicable.
    (b) A vessel may operate at a speed in excess of 10 knots (5.1 m/s) 
in an active designated SSZ or DSZ only if:
    (1) Justified because an emergency situation presents a threat to 
the health, safety, or life of a person;
    (2) Necessary to maintain safe maneuvering speed and justified 
because the vessel is in an area where oceanographic, hydrographic, 
and/or meteorological conditions severely restrict the maneuverability 
of the vessel and the need to operate at such speed is confirmed by the 
pilot on board or, when a vessel is not carrying a pilot, the master of 
the vessel; or
    (3) A vessel less than 65 ft (19.8 m) in length is transiting 
within areas where a National Weather Service Gale Warning, or other 
National Weather Service Warning (e.g., Storm Warning, Hurricane 
Warning) for wind speeds exceeding those that trigger a Gale Warning is 
in effect.
    (c) If a deviation from the requirements in paragraph (a) of this 
section is necessary under paragraph (b)(1) or (2) of this section, the 
vessel operator must complete and electronically submit an accurate and 
complete Safety Deviation Report to NMFS at https://www.fisheries.noaa.gov within 48 hours of the deviation. The Safety 
Deviation Report shall describe, in detail, the circumstances 
surrounding the deviation and need for the deviation on forms provided 
by NMFS. The vessel operator and, if the vessel is under pilotage at 
the time of the deviation, the pilot on board shall attest to the 
accuracy of the information in the Safety Deviation Report before it is 
submitted.
    (d) Except as provided under paragraph (b) of this section, it is 
unlawful for any person subject to the jurisdiction of the U.S. to 
commit, to attempt to commit, to solicit another to commit, or to cause 
to be committed any speed violation with a vessel subject to the 
restrictions established in paragraph (a) of this section or a 
reporting violation described in paragraph (c) of this section.
    (e) Any person or vessel claiming the applicability of any 
exception under paragraph (b) of this section has the burden of proving 
that the exception applies.
