Marine Mammals; Incidental Take of Polar Bears During Specified 
Activities; North Slope, Alaska

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule; availability of draft environmental assessment; 
request for comments.

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

SUMMARY: We, the U.S. Fish and Wildlife Service, propose to revise a 
portion of our regulations under the Marine Mammal Protection Act 
pertaining to incidental take of marine mammals. Existing regulations 
authorize the nonlethal, incidental, unintentional take by harassment 
of small numbers of polar bears from the Southern Beaufort Sea stock 
and Pacific walruses during year-round oil and gas industry activities 
in the Beaufort Sea (Alaska and the Outer Continental Shelf) and 
adjacent northern coast of Alaska. Such take may result from oil and 
gas exploration, development, production, and transportation activities 
occurring through August 5, 2026. The proposed revisions would 
authorize incidental take by Level A harassment of polar bears in 
addition to the incidental Level B harassment of polar bears and 
Pacific walruses already authorized in the existing regulations. No 
lethal take is or would be authorized. We request comments on these 
proposed regulations.

DATES: Comments on these proposed revisions to our incidental take 
regulations and the accompanying draft supplemental environmental 
assessment will be accepted on or before December 9, 2024.
    Information Collection Requirements: If you wish to comment on the 
information collection requirements in this proposed rule, please note 
that the Office of Management and Budget (OMB) is required to make a 
decision concerning the collection of information contained in this 
proposed rule between 30 and 60 days after publication of this proposed 
rule in the Federal Register. Therefore, comments should be submitted

SUPPLEMENTARY INFORMATION:

Background

    In accordance with the Marine Mammal Protection Act of 1972, as 
amended (MMPA; 16 U.S.C. 1371 et seq.), and its implementing 
regulations, the U.S. Fish and Wildlife Service (Service) finalized 
incidental take regulations in 2021 (2021-ITRs) in response to a 
request from the Alaska Oil and Gas Association (AOGA). The request was 
for regulations to provide for the issuance of letters of authorization 
(LOA) for incidental take of small numbers of Pacific walruses and 
Southern Beaufort Sea (SBS) polar bears during specified oil and gas 
industry (``Industry'') activities in the Beaufort Sea and adjacent 
northern coast of Alaska over a 5-year period (86 FR 42982, August 5, 
2021). The regulations were added to title 50 of the Code of Federal 
Regulations (CFR) in part 18 at subpart J and expire August 5, 2026. 
The 2021-ITRs authorize, via Service-issued LOAs, the incidental Level 
B harassment of up to 15 Pacific walruses and 92 SBS polar bears each 
year. The 2021-ITRs do not authorize (or facilitate the authorization 
of) any incidental Level A harassment or lethal take of any marine 
mammals during specified Industry activities, and any such take remains 
prohibited by the MMPA.
    The term ``take'' as defined by the MMPA, means to harass, hunt, 
capture, or kill, or attempt to harass, hunt, capture, or kill any 
marine mammal (16 U.S.C. 1362(13)). Harassment, as defined by the MMPA, 
for activities other than military readiness activities or scientific 
research conducted by or on behalf of the Federal Government, means 
``any act of pursuit, torment, or annoyance which (i) has the potential 
to injure a marine mammal or marine mammal stock in the wild'' (the 
MMPA defines this as Level A harassment); or ``(ii) has the potential 
to disturb a marine mammal or marine mammal stock in the wild by 
causing disruption of behavioral patterns, including, but not limited 
to, migration, breathing, nursing, breeding, feeding, or sheltering'' 
(the MMPA defines this as Level B harassment) (16 U.S.C. 1362(18)).
    The 2021-ITRs, along with the accompanying National Environmental 
Policy Act (NEPA) environmental assessment and Endangered Species Act 
(ESA) biological opinion, were challenged in litigation that commenced 
in the United States District Court for the District of Alaska 
(District Court). On March 30, 2023, the District Court issued summary 
judgment in favor of the Service upholding the 2021-ITRs. Portions of 
this ruling were appealed to the United States Court of Appeals for the 
Ninth Circuit (Appellate Court). On March 19, 2024, a three-judge panel 
of

[[Page 88217]]

the Appellate Court issued an order that affirmed in part, and reversed 
in part, the District Court ruling. The Appellate Court panel declined 
to vacate the 2021-ITRs but issued a remand that requires the Service 
to conduct additional analysis and, depending on the results, 
potentially take regulatory action. In their remand order, specific 
only to polar bears, the Court directed (omitting internal references): 
``We . . . remand to the Service to offer a fuller explanation for its 
determination that no Level A incidents are expected during the period 
covered by the 2021 ITR. . . . In assessing the `negligible impact' 
prong on remand, the Service may, consistent with its expertise, 
emphasize certain outputs over others. However, given the MMPA's two-
part conception of take, it must determine whether aggregating serious 
and non-serious Level A take yields a `reasonably likely' result. . . . 
If so (as the 75 percent figure proffered by Plaintiffs suggests), the 
Service will then need to determine (i) whether any Level A take 
predicted will affect only `small numbers' of bears and have a 
`negligible impact' on the subpopulation and, if so, (ii) whether to 
issue an updated ITR covering Level A take or no ITR at all.''
    The Court further stated, ``Hence, we . . . remand to the Service 
so that it may (i) aggregate serious and non-serious Level A take 
together . . . and (ii) determine whether the five-year risk of such 
take of a denning cub is `reasonably likely'. . . . To the extent that 
it is, the Service must then evaluate whether the five-year impacts of 
Level A take is `negligible' and whether such take will be of `small 
numbers' of bears and possibly amend or reverse the 2021 ITR.''
    Accordingly, the Service has conducted additional analysis 
consistent with the Appellate Court's direction. As discussed below, 
this new analysis has resulted in preliminary determinations that, 
while no lethal take is predicted to occur, it is likely that Level A 
harassments of polar bears will occur, and that authorizing such take 
is consistent with MMPA standards. Therefore, this proposed rule, if 
finalized, would amend the 2021-ITRs to allow the issuance of LOAs 
authorizing take by Level A harassment of polar bears that may result 
from Industry activities.
    Section 101(a)(5)(A) of the MMPA gives the Secretary of the 
Interior (Secretary) the authority to allow the incidental, but not 
intentional, taking of small numbers of marine mammals, in response to 
requests by U.S. citizens (as defined in 50 CFR 18.27(c)) engaged in a 
specified activity (other than commercial fishing) within a specified 
geographic region. The Secretary has delegated authority for 
implementation of the MMPA to the Service. According to the MMPA, the 
Service shall allow this incidental taking if we find the total of such 
taking for a 5-year period or less:
    (1) will affect only small numbers of marine mammals of a species 
or population stock;
    (2) will have no more than a negligible impact on such species or 
stocks;
    (3) will not have an unmitigable adverse impact on the availability 
of such species or stocks for taking for subsistence use by Alaska 
Natives; and
    (4) we issue regulations that set forth:
    (a) permissible methods of taking;
    (b) other means of effecting the least practicable adverse impact 
on the species or stock and its habitat, and on the availability of 
such species or stock for subsistence uses; and
    (c) requirements for monitoring and reporting of such taking.
    If final regulations allowing such incidental taking are issued, we 
may then subsequently issue LOAs, upon request, to authorize incidental 
take during the specified activities.
    The terms ``negligible impact'' and ``unmitigable adverse impact'' 
are defined in 50 CFR 18.27 (the Service's regulations governing small 
takes of marine mammals incidental to specified activities). 
``Negligible impact'' is 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. ``Unmitigable adverse impact'' 
means an impact resulting from the specified activity (1) that is 
likely to reduce the availability of the species to a level 
insufficient for a harvest to meet subsistence needs by (i) causing the 
marine mammals to abandon or avoid hunting areas, (ii) directly 
displacing subsistence users, or (iii) placing physical barriers 
between the marine mammals and the subsistence hunters; and (2) that 
cannot be sufficiently mitigated by other measures to increase the 
availability of marine mammals to allow subsistence needs to be met.
    The term ``small numbers'' is also defined in Sec.  18.27. However, 
we do not rely on that definition here as it conflates ``small 
numbers'' with ``negligible impacts.'' We recognize ``small numbers'' 
and ``negligible impacts'' as two separate and distinct requirements 
for promulgating incidental take regulations (ITRs) under the MMPA (see 
Natural Res. Def. Council, Inc. v. Evans, 232 F. Supp. 2d 1003, 1025 
(N.D. Cal. 2003)). Instead, for our small numbers determination, we 
estimate the likely number of takes of marine mammals and evaluate if 
that take is small relative to the size of the species or stock.
    The term ``least practicable adverse impact'' is not defined in the 
MMPA or its enacting regulations. The Service ensures the least 
practicable adverse impact by requiring mitigation measures that are 
effective in reducing the impact of Industry activities but are not so 
restrictive as to make Industry activities unduly burdensome or 
impossible to undertake and complete.
    The MMPA does not require Industry to obtain an incidental take 
authorization; however, any taking that occurs without authorization is 
a violation of the MMPA. Since 1993, the oil and gas industry operating 
in the Beaufort Sea and the adjacent northern coast of Alaska has 
requested, and we have issued, ITRs for the incidental take of Pacific 
walruses and polar bears within a specified geographic region during 
specified activities. For a detailed history of our current and past 
Beaufort Sea ITRs, refer to the Federal Register at 81 FR 52276, August 
5, 2016; 76 FR 47010, August 3, 2011; 71 FR 43926, August 2, 2006; and 
68 FR 66744, November 28, 2003. The current regulations are codified at 
50 CFR part 18, subpart J (Sec. Sec.  18.121 through 18.129), and were 
published in the Federal Register on August 5, 2021 (86 FR 42982).

Proposed Changes to 50 CFR Part 18, Subpart J

    Our reanalysis, as discussed in detail below, indicates that Level 
A harassment of polar bears is reasonably likely to occur during the 5-
year effective period of the 2021-ITRs. Therefore, we are proposing 
revisions to our regulations that, if finalized, would allow the 
Service to authorize take by both Level A and Level B harassment of 
polar bears. The lethal incidental take of polar bears would continue 
to be prohibited under this proposed revision, as would any Level A 
harassment or lethal take of Pacific walrus.

New Information and Analysis

Aggregated Level A Harassment Across 5-Year Period

    In conducting the additional analysis required by the Court's 
remand, the Service utilized best available scientific evidence. New 
information has been acquired and several advancements in the Service's 
analytical methods have been made subsequent to the promulgation of the 
2021-ITRs. Many of

[[Page 88218]]

these advancements were recently described and considered in an 
incidental harassment authorization that was issued by the Service to 
the Bureau of Land Management (88 FR 88943, December 26, 2023).
    Specifically, the denning analysis described in the 2021-ITRs was 
conducted using the simulation of annual land-based maternal polar bear 
dens, spatially and temporally explicit descriptions of Industry 
activity, and predictions of polar bear response rooted in 
distributions established from den disturbance case studies (see 86 FR 
42982, August 5, 2021). For each of the five winter seasons analyzed in 
the 2021-ITRs, a series of dens were simulated by assigning each a 
location on the landscape, the sow's entrance date, the number of cubs 
she bore, the cub(s)' birthdate, den emergence date, and den departure 
date. We then overlaid the season's Industry activity across the same 
landscape and simulated whether polar bears within maternal dens that 
fell within a mile of activity responded to Industry-caused 
disturbances, and if so, how. Potential responses include disturbance 
of the sow inside the den, den abandonment, early emergence from the 
den, and early departure from the den site. Polar bear disturbance 
responses that occurred during the den establishment period were 
estimated to result in Level B harassment of the sow (no cubs are 
present during this period). Responses that occurred during the early 
denning period were estimated to result in Level B harassment of the 
sow and lethal take of the cub(s). Responses that occurred during the 
late denning period were estimated to result in Level B harassment of 
the sow and ``serious Level A harassment'' (i.e., likely to result in 
cub mortality) of the cub(s). Responses during the post-emergence 
period were estimated to result in Level B harassment of the sow and 
``non-serious Level A harassment'' (i.e., not likely to result in cub 
mortality) of the cub(s).
    The denning model was created to assess individual denning seasons 
and has included several levels of assumptions that generate an 
estimate of the potential annual impacts to denning polar bears that is 
somewhat conservative in that it is more likely to overstate, rather 
than understate, potential impacts. Use of this methodology achieved 
the objective of ensuring that actual impacts would not exceed what was 
contemplated in the incidental take authorization and would remain 
consistent with applicable MMPA thresholds. However, when applied to 
activities spanning a 5-year period, conservative aspects of certain 
model assumptions are amplified in a manner that risks unduly 
overstating projected aggregate impacts, raising the possibility that 
incidental take resulting from specified activities with acceptable 
levels of impacts could not be authorized, a scenario that would be 
inconsistent with the intent of section 101(a)(5)(A) of the MMPA. Thus, 
in complying with the remand's direction to aggregate Level A 
harassment estimates over a 5-year period, we reexamined the denning 
model to incorporate newly available scientific evidence and further 
refine certain model assumptions where appropriate to achieve greater 
accuracy.
    Since 2021, LOA applicants have annually provided the Service with 
revised project descriptions and geospatial files that more precisely 
reflected the scope of their planned activities to be conducted during 
the ensuing (1-year) LOA period, as compared with the descriptions of 
specified activities provided during development of the 5-year ITRs. We 
used the revised files in the present analysis as they constitute the 
best available information concerning the scope of Industry's specified 
activities. We also account for AOGA's clarification that no onshore 
terrestrial seismic surveys will occur during the winter of 2024-2025. 
Potential seismic surveys in the winter of 2025-2026 remain within the 
scope of AOGA's specified activities and were analyzed during our re-
analysis.
    As a condition of their authorizations, LOA holders also submit 
records of all polar bear encounters during their activities. Using 
this information, and records from separate activities that were not 
operating under the 2021-ITRs, we incorporated data from recently 
observed dens into our disturbance probabilities and litter size 
distributions, modified the model to incorporate newly published data 
that describes the relationship between den emergence date, den 
departure time, and litter survival (Andersen et al. 2024), and updated 
the simulation of dens across the landscape to now include several 
previously unidentified areas that may sustain polar bear dens.
    Four known dens (monitored in 2022 and 2023) have occurred near 
human activity since the promulgation of the 2021-ITRs. Of the four 
newly observed dens, three were extremely close to human activity (<50 
meters), yet the sows remained in their dens until the late denning 
period. We updated polar bear disturbance probabilities and litter size 
distributions with the information from these dens, then reexamined the 
historic dens that were used to create disturbance probabilities. We 
found that the distances between human activity and polar bear dens 
that experienced an observed disturbance response during the early 
denning period were considerably closer than those dens that experience 
an observed disturbance response during other denning periods. 
Specifically, of the 15 dens within the case studies that were exposed 
to human activity during the early denning period, only 1 was 
potentially disturbed at a distance greater than 800 meters. This 
single den record also had imprecise information on the distance to 
human activity, so activity was assumed to occur within 1,610 meters of 
the den and was likely closer.
    The historic dens analyzed during the den establishment, late 
denning, and post-emergence periods did not follow this pattern. For 
those dens, disturbance distances commonly exceeded 805 meters. 
Evidence derived from dens exposed to human activity during the early 
denning period, including both new den records and historic dens, 
illustrates the reluctance of sows to abandon their maternal den/cubs 
in response to exposure to stimuli from nearby activity and support the 
concept that sows may be more risk tolerant during the early denning 
period. Additionally, sows may be less affected by sound from outside 
activities during the early denning period because dens are typically 
closed during that time, which can reduce propagation of noise into the 
den (Owen et al. 2021). Given this evidence, we modified the denning 
analysis model to adjust the impact area for the early denning period 
to range from 0 to 805 meters. As a result, dens that were simulated to 
be within 805 meters of human activity could be disturbed during all 
denning periods, while dens between 806-1,610 meters of human activity 
could be disturbed only during the den establishment, late denning, and 
post-emergence periods.
    Finally, the method for categorizing certain disturbance responses 
was modified to comply with the Court's direction to provide aggregated 
estimates of Level A harassment and to better align the model results 
with the categories of ``take'' defined in the MMPA. In the preamble to 
the 2021-ITRs, we drew a distinction between ``serious Level A'' and 
``non-serious Level A'' harassment and largely addressed these 
categories separately. If a sow and cub(s) emerged early (i.e., during 
the late denning period), the litter was assigned serious Level A 
harassment(s). If the sow and cub(s) departed the den site early (i.e., 
during the post-emergence period), the litter

[[Page 88219]]

was assigned non-serious Level A harassment(s). These categories were 
based on the historic den disturbance case studies. Now we omit the 
``serious''/``non-serious'' dichotomy and instead report results that 
aggregate all estimated Level A harassments. If an exposure resulted in 
disturbance during either of these periods, we assigned a Level A 
harassment to each cub in the litter (table 1).

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

    We also use newly described relationships between den emergence 
date, den departure time, and litter survival (Andersen et al. 2024) to 
assign litter survival rates to simulated dens that experienced Level A 
harassment, a method used in recent polar bear take authorizations (88 
FR 88943, December 26, 2023). If an exposure resulted in a disturbance 
response during the late denning period, we first assigned that den a 
new random earlier emergence date. We then simulated whether that den 
was disturbed during the post-emergence period. Dens that were 
disturbed during the post-emergence period were also assigned a new 
random earlier den departure date. We relied on estimates of litter 
survival derived from empirical data from approximately 100 days post 
emergence (Andersen et al. 2024) to determine the fitness consequence 
of the Level A harassment, and we consider this information below when 
addressing the MMPA's negligible impact standard. This revised 
methodology provides a clearer and more in-depth understanding of the 
potential fitness consequence of polar bear disturbance.
    As in the existing 2021-ITRs, some concepts and mitigation measures 
could potentially reduce impacts to polar bears, but they are not 
reflected in our take estimates because their mitigative benefit is not 
quantifiable. For example, LOA holders must train their staff to 
identify the characteristics of a polar bear den, and if a suspected 
den is identified, they must cease operations and notify the Service. 
However, the efficacy of this technique cannot be quantified and could 
not be accounted for in the model results. Consideration of the 
conservative nature of certain model assumptions along with qualitative 
factors suggests that if the actual number of Level A harassment events 
does not align with the median model output, the actual number of Level 
A harassment events would be fewer than modeled. However, we 
preliminarily find, based on best professional judgment, that Level A 
harassment is reasonably likely to occur, and is anticipated, during 
the 5-year period of the 2021-ITRs (table 2).

----------------------------------------------------------------------------------------------------------------
* Confidence interval (CI).

    We base this conclusion on the strength of the modeled probability 
of Level A harassment (0.93), the estimated median number of 
harassments (5), and denning observations that have occurred within the 
area of the 2021-ITRs subsequent to the promulgation of the regulations 
in 2021. Of the four dens that have been observed within 1 mile of the 
human activity since 2021, two polar bear family groups appear to have 
spent less time at the den site during the post emergence period than 
average. Following the relationship between den emergence date and den 
departure date described by Andersen et al. (2024), the cubs in the 
early departing family groups may have experienced a reduction in 
fitness and, as a result, a temporary decrease in their probability of 
survival. The Service considers such reductions in fitness as 
``injuries'' for the purposes of interpreting the MMPA's definition of 
Level A harassment.

Updated and Revised Findings

    Our reanalysis has led to the conclusion that Level A harassment of 
polar bears is reasonably likely to occur during the 5-year effective 
period of the 2021-ITRs. Due to this conclusion, and in light of the 
Court's remand, we propose to revise aspects of the 2021-ITRs that 
pertain to polar bears (but not Pacific walruses).

Updated ``Small Numbers'' and ``Negligible Impact'' Determinations

    In conducting analysis for this proposed revision to the 2021-ITRs, 
we began by focusing on the impact of AOGA's specified activities that 
may occur during the 2 remaining years of the 2021-ITRs (which expire 
August 5, 2026), i.e., the activities to which revised regulations 
would apply. Using the updated information and denning model 
methodology described above, we estimated the potential Level B 
harassment, Level A harassment, and lethal take of denning polar bears 
that may occur as a result of these specified activities (table 3).

Small Numbers

    We propose a determination that AOGA's specified activities between 
December 1, 2024, and August 5, 2026, would incidentally take small 
numbers of SBS polar bears. For this determination, we consider whether 
the estimated number of marine mammals to be subjected to incidental 
take is small relative to the population size of the species or stock.
    1. Within the specified geographical region, the area of Industry 
activity is expected to be small relative to the range of polar bears. 
SBS polar bears range well beyond the boundaries of the Beaufort Sea 
2021-ITRs region. As such, the region represents only a subset of the 
potential area in which SBS polar bears may occur. Further, only seven 
percent of the 2021-ITRs area (518,800 ha of 7.9 million ha) is 
estimated to be impacted by Industry activities, even accounting for a 
disturbance zone surrounding industrial facility and transit routes. 
Thus, the area of Industry activity will be relatively small compared 
to the range of polar bears.
    We expect that only small numbers of the SBS polar bear stock would 
be taken by the Industry activities specified in the 2021-ITRs because 
SBS polar bears are widely distributed throughout their expansive 
range, which encompasses areas beyond the Beaufort Sea 2021-ITRs 
region, meaning only a small proportion of the SBS polar bear stock 
will occur in the areas where Industry activities will occur, and the 
estimated number of polar bears that could be impacted by the specified 
activities is small relative to the size of the stock.
    2. The estimated number of polar bears that will be harassed by 
Industry activity is small relative to the number of animals in their 
stocks. The Beaufort Sea 2021-ITRs region is completely within the 
range of the SBS stock of polar bears, and during some portions of the 
year polar bears can be frequently encountered by Industry. From 2014 
through 2018, Industry made 1,166 polar bear reports comprising 1,698 
bears. However, when we evaluated the effects upon the 1,698 bears 
observed, we found that 84 percent (1,434) did not experience take. 
Over those 5 years, Level B harassments of polar bears totaled 264, 
approximately 15.5 percent of the observed bears. No other forms of 
take or harassment were observed. Annually an average of 340 polar 
bears were observed during Industry activities. The number of observed 
Level B harassment events averaged 53 per year from 2014 to 2018. We 
conclude that over the remaining 2 years of the 2021-ITRs, Industry 
activities will result in a similarly small number of incidental 
harassments of polar bears.
    Based on this information derived from Industry observations, along 
with the results of the Service's own predictive modeling analysis 
described above, we estimate that no more than 184 Level B harassment 
takes and 2 Level A harassment takes of polar bears will occur during 
the remaining 2 years of the 2021-ITRs, with no more than 92 Level B 
and 2 Level A harassment takes occurring within a single year. 
Conservatively assuming that, in a given year, each estimated take will 
accrue to a different individual polar bear, we note that take of 94 
animals is 10.36 percent of the best available estimate of the current 
stock size of 907 animals in the SBS stock (Bromaghin et al. 2015, 
Atwood et al. 2020) ((94 / 907) x 100 [ap] 10.36), and we propose a 
finding that this proportion represents a ``small number'' of polar 
bears of that stock. While we do not have data to estimate the 
frequency of repeated Level B harassments to the same polar bear in 
different years, polar bears exhibiting terrestrial habitat preferences 
may be harassed repeatedly. Thus, it is highly probable that the number 
of individuals experiencing Level B harassment over the 2024-2026 
period is less than 184.
    While the Service does not propose to retroactively authorize any 
incidental take, we also address the remand directive to ``evaluate the 
five-year impacts of Level A take'' and determine whether that take 
``will be of `small numbers' of bears.'' Once again conservatively 
assuming that each estimated take over the 5-year period accrues to a 
different individual polar bear, we note that take is not anticipated 
to exceed 94 animals in any of the 5 years and take of 94 animals is 
10.36 percent of the best available estimate of the current stock size 
of 907 animals in the SBS stock. This proportion represents a ``small 
number'' of polar bears of that stock. We conservatively base this 
preliminary determination on all the specified activities originally 
described in AOGA's request, i.e., without discounting the estimated 
take associated with specified activities that were planned for the 
initial 3 years of the 2021-ITR but did not actually occur.

Negligible Impact

    We proposed a determination that AOGA's specific activities would 
result in a negligible impact to the SBS stock of polar bears. For our 
negligible impact determination finding, we consider the following:
    1. The number of polar bears that use the terrestrial habitat of 
the North Slope is small in relation to the entire SBS stock. The 
distribution and habitat use patterns of polar bears indicate that 
relatively few polar bears will occur in the specified areas of 
activity at any particular time and, therefore, few polar bears are 
likely to be affected.
    2. Mitigation measures will reduce potential impacts. If this 
proposed rule is finalized, the applicant will be required to adopt 
monitoring requirements and mitigation measures designed to reduce the 
potential impacts of their operations on polar bears. Den detection 
surveys for polar bears and adaptive mitigation and management 
responses based on real-time monitoring information (described in this 
proposed rule) will be used to avoid or minimize interactions with 
polar bears and, therefore, limit potential disturbance of these 
animals.
    3. The majority of human-polar bear interactions will result in no 
effect or short-term, temporary behavioral changes. When developing 
estimates for Level B harassment, we have determined that there is a 99 
percent chance that at least 81 percent of encounters with bears on the 
surface in the open water season and 63 percent of encounters with 
bears on the surface in

[[Page 88221]]

the ice season are expected to result in no significant change in a 
biologically important behavior. The remainder of encounters are 
anticipated to result in short-term, temporary changes in behavior.
    4. Few dens would occur in proximity to Industry activities. Our 
denning simulations show that on average six dens are estimated to 
occur within 1 mile of the specified activities during each of the next 
two denning seasons (2024-2025 and 2025-2026). This number represents 
roughly 5 percent of the approximately 120 SBS polar bear dens that are 
established each year. The mitigation measures required by the 2021-
ITRs reduce the estimated number of Level A disturbed dens to 1.8 
percent of the land-based dens and 0.9 percent of all dens in the SBS 
stock (figure 1).

Figure 1--Proportion of SBS land-based dens that are estimated to 
experience Level A disturbance each year. Land-based dens represent 
roughly half of the SBS maternal polar bear dens established each year.

    5. Anticipated Level A harassments will not alter the distribution 
of cub survival probabilities for the SBS stock. We anticipate two 
Level A harassment events may occur as a result of the specified 
activities over a period of 2 years. The updated denning analysis model 
allows us to examine the simulated dens to estimate the probability of 
litter survival to 100 days using both their undisturbed and disturbed 
(if applicable) emergence and departure dates. With this information, 
we can determine the average decrease in survival probability that can 
be attributed to potential Industry disturbance. Only 0.9 percent of 
dens within the SBS stock are anticipated to experience Level A 
harassment annually. For those dens that experience harassment, the 
mean probability of litter survival before disturbance was 87.3 
percent. After simulating disturbance, the mean probability of litter 
survival was 72.8 percent, a decrease of 14 percent. However, given the 
low percentage of SBS dens that are anticipated to experience Level A 
harassment, the 14 percent decrease does not alter or shift the overall 
survival probability distribution for the SBS stock (figure 2).
BILLING CODE 4333-15-P

land-based dens of the SBS polar bear stock (Graph A: Survival 
probabilities simulated with no disturbance from Industry; Graph B: 
Survival probabilities simulated with estimated Level A harassment from 
Industry activities).

BILLING CODE 4333-15-C
    6. Lethal take via den abandonment is rare within the Southern 
Beaufort Sea stock. Records of den abandonment in the oilfield are 
rare--we have only 2 accounts of potential den abandonment within the 
15 case studies used to develop early denning period disturbance rates. 
Applying the denning model, the greatest annual probability of lethal 
take in the final 2 years of the 2021-ITRs is 0.31. The aggregated 
probability of lethal take over a 2-year period is 0.45, indicating 
lethal take due to sow abandonment of the den and litter during the 
early denning period is unlikely. We do not believe the estimate of 
lethal take is inaccurate; however, it is potentially conservative.
    7. We do not anticipate that loss of a cub or litter will adversely 
affect annual recruitment rates at the population level. If a den is 
disturbed and the disturbance resulted in cub mortality, such take 
would not be authorized under the revised 2021-ITRs. Any Level A 
harassment would be limited to only cubs during the denning period. 
Impacts to denning females, the demographic group most important to 
annual recruitment, would be limited to take by Level B harassment. 
Therefore, the immediate number of potentially available reproductive 
females that would contribute to recruitment for the SBS stock would 
remain unaffected if a den disturbance were to result in the mortality 
of the cubs. If a den disturbance were to result in the mortality of 
the entire litter, the female would be available to breed during the 
next mating season and produce another litter during the next denning 
season.
    Cubs inherently cannot contribute to annual rates of recruitment 
until they have reached sexual maturity. Further, while adult male 
bears would contribute to the overall number of individuals in the 
population, they do not contribute significantly to annual rates of 
recruitment. While a very small decrease in the number of males in a 
breeding population may be a concern if the stock was at risk of 
inbreeding depression or allee effects, this is not the case in the SBS 
stock. Female cubs have the opportunity to reach sexual maturity and 
contribute to annual recruitment; however, natural rates of survival 
fluctuate in the SBS stock. As such, death of less than one female cub 
per year is within the natural variability found within the SBS stock 
and cannot be reasonably expected to cause an adverse impact on annual 
rates of recruitment.
    Based on the low percentage of SBS stock polar bears potentially 
being removed from the stock if den disturbance were to result in the 
mortality of the cubs, and the expectation that the number of 
potentially available reproductive females that would contribute to 
recruitment would be unaffected by den disturbance, the Service does 
not anticipate that the loss of a cub or litter would adversely affect 
annual recruitment rates at the population level for the SBS stock of 
polar bears.
    We reviewed the effects of Industry activities on polar bears, 
including impacts from surface interactions, aircraft overflights, 
marine vessel traffic, and den disturbance. Based on our

[[Page 88223]]

review of these potential impacts, past monitoring reports, and the 
biology and natural history of polar bears, we conclude that any 
incidental take reasonably likely to occur as a result of specified 
activities would be limited to short-term behavioral disturbances and 
temporary reductions in fitness that would not affect the rates of 
recruitment or survival for the SBS stock of polar bears.
    We have analyzed the potential impact of the proposed taking in 
light of other factors affecting SBS polar bears, including subsistence 
harvest and other human-caused removals as well as climate change. 
Climate change is a global phenomenon and was considered as the overall 
driver of effects that could alter polar bear habitat and behavior. The 
Service is currently involved in research to understand how climate 
change may affect polar bears. As we gain a better understanding of 
climate change effects, we will incorporate the information in future 
authorizations. While climate change and other ongoing factors pose 
significant challenges to SBS polar bears, we do not expect them to 
influence the degree of impacts (i.e., short-term behavioral responses 
and temporary reductions in fitness) resulting from the specified 
activities or incidental harassment to be authorized under a revised 
ITR.
    Our analysis indicates that the impacts of these specified 
activities over the remaining 2 years addressed by the 2021-ITRs cannot 
be reasonably expected to, and are not reasonably likely to, adversely 
affect the SBS stock of polar bears through effects on annual rates of 
recruitment or survival. We therefore propose a determination that the 
total of the taking estimated above and to be authorized via the 
revised 2021-ITRs will have no more than a negligible impact on the SBS 
stock of polar bears.
    While the Service does not propose to retroactively authorize any 
incidental take, we also address the remand directive to ``evaluate 
whether the five-year impacts of Level A take is `negligible.' '' 
Because we do not anticipate adverse effects to the SBS stock through 
effects on annual rates or recruitment or survival over the remaining 2 
years, and because the scope of specified activities and the extent of 
estimated impacts is largely consistent across each year of the 5-year 
period, we propose a determination that the total of the taking 
estimated above over the 5-year period cannot be reasonably expected 
to, and is not reasonably likely to, adversely affect the SBS stock of 
polar bears through effect on annual rates or recruitment or survival, 
and thus will have no more than a negligible impact on the SBS stock of 
polar bears. We conservatively base this preliminary determination on 
all the specified activities originally described in AOGA's request, 
i.e., without discounting the estimated impacts of specified activities 
that were planned for the initial 3 years of the 2021-ITR but did not 
actually occur.

Reevaluation of Other ITR Provisions

    We have not identified any means through which the Level A 
harassment described above, in combination with the Level B harassment 
already contemplated in the 2021-ITRs, is likely to reduce the 
availability of SBS polar bears to a level insufficient for harvest to 
meet subsistence needs. Thus, we preliminarily reaffirm our finding 
that the total taking will not have an unmitigable adverse impact on 
the availability of SBS polar bears or Pacific walruses for taking for 
subsistence uses.
    We have not identified any additional (i.e., not already 
incorporated into the 2021-ITRs) mitigation measures that are effective 
in reducing the impact of Industry activities but are not so 
restrictive as to make Industry activities unduly burdensome or 
impossible to undertake and complete. Thus, we preliminarily reaffirm 
our finding that the mitigation measures required by the 2021-ITRs will 
ensure the least practicable adverse impacts on SBS polar bears and 
Pacific walruses.
    We have not identified any additional (i.e., not already 
incorporated into the 2021-ITRs) monitoring or reporting requirements 
to better assess the effects of industrial activities, ensure that the 
number of takes and the effects of taking are consistent with that 
anticipated in the ITR, or detect any unanticipated effects on SBS 
polar bears or Pacific walruses.

Administrative Updates

    In addition to proposing amendments to the regulations in 50 CFR 
part 18 to accomplish the regulatory revisions described above, we also 
propose regulatory revisions to update our regulations that carry out 
the Paperwork Reduction Act (PRA; 44 U.S.C. 3501 et seq.). The proposed 
revisions to Sec. Sec.  18.4, 18.129, and 18.152 that are set forth in 
the rule portion of this document are administrative and 
nonsubstantive. These proposed changes would serve only to update and 
streamline the regulatory text that ensures our regulations in 50 CFR 
part 18 are in compliance with the PRA.

Required Determinations

National Environmental Policy Act (NEPA)

    We have prepared a draft supplemental environmental assessment in 
accordance with NEPA (42 U.S.C. 4321 et seq.). We have preliminarily 
concluded that the proposed revisions to additionally authorize two 
takes by Level A harassment of polar bears during the remaining 2 years 
of the 2021-ITRs would not significantly affect the quality of the 
human environment and, thus, preparation of an environmental impact 
statement for this proposed rule is not required by section 102(2) of 
NEPA or its implementing regulations. We are accepting comments on the 
draft environmental assessment as specified above in DATES and 
ADDRESSES.

Endangered Species Act (ESA; 16 U.S.C. 1531 et seq.)

    Under the ESA, all Federal agencies are required to ensure the 
actions they authorize are not likely to jeopardize the continued 
existence of any threatened or endangered species or result in 
destruction or adverse modification of critical habitat. The polar bear 
is listed as a threatened species under the ESA at 50 CFR 17.11(h) with 
provisions

[[Page 88224]]

issued under section 4(d) of the ESA at 50 CFR 17.40(q) and designated 
critical habitat for polar bear subpopulations in the United States at 
50 CFR 17.95(a). On August 3, 2021, the Service issued a biological 
opinion on the 2021-ITRs, concluding that, ``[Issuance of the 2021-
ITRs] is not likely to jeopardize the continued existence of polar 
bears by appreciably reducing the likelihood of both survival and 
recovery of the species in the wild by reducing its reproduction, 
numbers, or distribution.'' Because this proposed regulation change, if 
finalized, would allow both Level A and B taking of polar bears, 
whereas the 2021-ITRs provide for only Level B taking of polar bears, 
our Marine Mammal Management Office has re-initiated intra-Service ESA 
section 7 consultation regarding the effects of these proposed 
regulations with our Fairbanks' Ecological Services Field Office. We 
would complete the consultation prior to finalizing these proposed 
regulation revisions.

Regulatory Planning and Review (Executive Orders 12866, 13563, and 
14904)

    Executive Order (E.O.) 14094 amends and reaffirms the principles of 
E.O. 12866 and E.O. 13563 and states that regulatory analysis should 
facilitate agency efforts to develop regulations that serve the public 
interest, advance statutory objectives, and are consistent with E.O. 
12866 and E.O. 13563, and the Presidential Memorandum of January 20, 
2021 (Modernizing Regulatory Review). Regulatory analysis, as 
practicable and appropriate, shall recognize distributive impacts and 
equity, to the extent permitted by law. Executive Order 13563 
emphasizes further that regulations must be based on the best available 
science and that the rulemaking process must allow for public 
participation and an open exchange of ideas. We have developed this 
proposed rule in a manner consistent with these requirements.

Small Business Regulatory Enforcement Fairness Act

    We have determined that this proposed rule is not a major rule 
under 5 U.S.C. 804(2), the Small Business Regulatory Enforcement 
Fairness Act. This proposed rule is not likely to result in a major 
increase in costs or prices for consumers, individual industries, or 
government agencies or have significant adverse effects on competition, 
employment, productivity, innovation, or on the ability of United 
States-based enterprises to compete with foreign-based enterprises in 
domestic or export markets.

Regulatory Flexibility Act

    We have also determined that this proposed rule would not have a 
significant economic effect on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Oil 
companies and their contractors conducting exploration, development, 
and production activities in Alaska have been identified as the only 
likely applicants under the regulations, and these potential applicants 
have not been identified as small businesses. Therefore, neither a 
regulatory flexibility analysis nor a small entity compliance guide is 
required.

Takings Implications

    This proposed rule does not have takings implications under 
Executive Order 12630 because it authorizes the nonlethal, incidental, 
but not intentional, take of polar bears by Industry and thereby, 
exempts these companies from civil and criminal liability as long as 
they operate in compliance with the terms of their LOAs. Therefore, a 
takings implications assessment is not required.

Federalism Effects

    This proposed rule does not contain policies with federalism 
implications sufficient to warrant preparation of a federalism 
assessment under Executive Order 13132. The MMPA gives the Service the 
authority and responsibility to protect polar bears.

Unfunded Mandates Reform Act

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
et seq.), this proposed rule would not ``significantly or uniquely'' 
affect small governments. A small government agency plan is not 
required. The Service has determined and certifies pursuant to the 
Unfunded Mandates Reform Act that this rulemaking would not impose a 
cost of $100 million or more in any given year on local or State 
governments or private entities. Therefore, this proposed rule is not a 
``significant regulatory action'' under the Unfunded Mandates Reform 
Act.

Government-to-Government Coordination

    It is our responsibility to communicate and work directly on a 
government-to-government basis with federally recognized Alaska Native 
Tribes in developing programs for healthy ecosystems. We seek their 
full and meaningful participation in evaluating and addressing 
conservation concerns for protected species. It is our goal to remain 
sensitive to Alaska Native culture, and to make information available 
to Alaska Tribal organizations and communities. Our efforts are guided 
by the following policies and directives:
    (1) The Native American Policy of the Service (January 20, 2016);
    (2) The Alaska Native Relations Policy (currently in draft form; 
see 87 FR 66255, November 3, 2022);
    (3) Executive Order 13175 (January 9, 2000);
    (4) Department of the Interior Secretary's Orders 3206 (June 5, 
1997), 3225 (January 19, 2001), 3317 (December 1, 2011), 3342 (October 
21, 2016), and 3403 (November 15, 2021) as well as Director's Order 227 
(September 8, 2022);
    (5) The Alaska Government-to-Government Policy (a departmental 
memorandum issued January 18, 2001); and
    (6) the Department of the Interior's policies on consultation with 
Alaska Native Tribes and organizations.
    We have evaluated possible effects of the proposed rule on 
federally recognized Alaska Native Tribes and ANCSA (Alaska Native 
Claims Settlement Act) Corporations. The Service has determined that 
authorizing two takes by Level A harassment of polar bears during the 
remaining 2 years of the 2021-ITRs, with no more than two Level A 
harassment takes occurring within a single year from the SBS stock of 
polar bears, would not have any Tribal implications or ANCSA 
Corporation implications and, therefore, government-to-government 
consultation or Government-to-ANCSA Corporation consultation is not 
necessary. However, we invite continued discussion through the public 
comment process.

Civil Justice Reform

    The Department's Office of the Solicitor has determined that these 
proposed regulations do not unduly burden the judicial system and meet 
the applicable standards provided in sections 3(a) and 3(b)(2) of 
Executive Order 12988.

Paperwork Reduction Act

    This proposed rule requests a revision to an existing information 
collection. All information collections (ICs) require approval under 
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). We may 
not conduct or sponsor, and you are not required to respond to, a 
collection of information unless it displays a currently valid OMB 
control number. The OMB previously reviewed and approved the 
information collection requirements associated with incidental take of 
marine mammals in 50 CFR part 18, subparts J and L, and assigned OMB

[[Page 88225]]

Control Number 1018-0070 (expires July 31, 2026).
    In accordance with the PRA and its implementing regulations at 5 
CFR 1320.8(d)(1), we provide the general public and other Federal 
agencies with an opportunity to comment on our proposal to revise OMB 
Control Number 1018-0070 and on our request for a new control number as 
described below. This input will help us assess the impact of our 
information collection requirements and minimize the public's reporting 
burden. It will also help the public understand our information 
collection requirements and provide the requested data in the desired 
format.
    As part of our continuing effort to reduce paperwork and respondent 
burdens, and in accordance with 5 CFR 1320.8(d)(1), we invite the 
public and other Federal agencies to comment on any aspect of this 
proposed information collection, including:
    (1) Whether or not the collection of information is necessary for 
the proper performance of the functions of the agency, including 
whether or not the information will have practical utility;
    (2) The accuracy of our estimate of the burden for this collection 
of information, including the validity of the methodology and 
assumptions used;
    (3) Ways to enhance the quality, utility, and clarity of the 
information to be collected; and
    (4) Ways to minimize the burden of the collection of information on 
those who are to respond, including through the use of appropriate 
automated, electronic, mechanical, or other technological collection 
techniques or other forms of information technology, e.g., permitting 
electronic submission of response.
    Comments that you submit in response to this proposed rulemaking 
are a matter of public record. Before including your address, phone 
number, email address, or other personal identifying information in 
your comment, you should be aware that your entire comment--including 
your personal identifying information--may be made publicly available 
at any time. While you can ask us in your comment to withhold your 
personal identifying information from public review, we cannot 
guarantee that we will be able to do so.
    This is a nonform collection. Respondents must comply with the 
regulations at 50 CFR part 18, which outline the procedures and 
requirements for submitting a request. Specific regulations governing 
authorized incidental take of marine mammal activities are contained in 
50 CFR part 18, subparts J (incidental take of polar bears and Pacific 
walruses in the Beaufort Sea) and L (incidental take of northern sea 
otters in the Gulf of Alaska). These regulations provide the applicant 
with a detailed description of information that we need to evaluate the 
proposed activity and determine if it is appropriate to issue specific 
regulations and, subsequently, LOAs. We use the information to verify 
the findings required to issue incidental take regulations, to decide 
if we should issue an LOA, and (if an LOA is issued) what conditions 
should be included in the LOA. In addition, we analyze the information 
to determine impacts to polar bears, Pacific walruses, northern sea 
otters, and the availability of those marine mammals for subsistence 
purposes of Alaska Natives.
    In conjunction with this rulemaking, we propose the following 
revisions for OMB approval:
    (1) Revise and renew OMB Control No. 1018-0070 to retain the 
currently approved ICs and burden estimates associated with 50 CFR part 
18, subpart J--Beaufort Sea--This ITR in subpart J, issued to the 
Alaska Oil and Gas Association (AOGA) is effective August 5, 2021, 
through August 5, 2026. It authorizes the nonlethal incidental, but not 
intentional, take of small numbers of polar bear and Pacific walrus for 
oil and gas exploration, development, and production activities in the 
Beaufort Sea and adjacent northern coast of Alaska. Unless a new ITR is 
issued for subpart J, we will discontinue OMB Control No. 1018-0070 
when the ITR expires in 2026.
    We request OMB approval to renew the following ICs and to adjust 
the currently approved burden associated with the ICs in subpart J that 
will remain in OMB Control No. 1018-0070:
    (A) Incidental Take of Marine Mammals--Application for 
Regulations--Regulations at 50 CFR part 18 require the applicant to 
provide information on the activity as a whole, which includes, but is 
not limited to, an assessment of total impacts by all persons 
conducting the activity. Applicants can find specific requirements in 
50 CFR part 18, subpart J. These regulations provide the applicant with 
a detailed description of information that we need to evaluate the 
proposed activity and determine whether to issue specific regulations 
and, subsequently, LOAs. The required information includes:
    1. A description of the specific activity or class of activities 
that can be expected to result in incidental taking of marine mammals.
    2. The dates and duration of such activity and the specific 
geographical region where it will occur.
    3. Based on the best available scientific information, each 
applicant must also provide:
    a. An estimate of the species and numbers of marine mammals likely 
to be taken by age, sex, and reproductive conditions;
    b. The type of taking (e.g., disturbance by sound, injury or death 
resulting from collision, etc.) and the number of times such taking is 
likely to occur;
    c. A description of the status, distribution, and seasonal 
distribution (when applicable) of the affected species or stocks likely 
to be affected by such activities;
    d. The anticipated impact of the activity upon the species or 
stocks; and
    e. The anticipated impact of the activity on the availability of 
the species or stocks for subsistence uses.
    4. The anticipated impact of the activity upon the habitat of the 
marine mammal populations and the likelihood of restoration of the 
affected habitat.
    5. The availability and feasibility (economic and technological) of 
equipment, methods, and manner of conducting such activity or other 
means of effecting the least practicable adverse impact upon the 
affected species or stocks, their habitat, and, where relevant, on 
their availability for subsistence uses, paying particular attention to 
rookeries, mating grounds, and areas of similar significance. (The 
applicant and those conducting the specified activity and the affected 
subsistence users are encouraged to develop mutually agreeable 
mitigating measures that will meet the needs of subsistence users.)
    6. Suggested means of accomplishing the necessary monitoring and 
reporting that will result in increased knowledge of the species 
through an analysis of the level of taking or impacts and suggested 
means of minimizing burdens by coordinating such reporting requirements 
with other schemes already applicable to persons conducting such 
activity.
    7. Suggested means of learning of, encouraging, and coordinating 
research opportunities, plans, and activities relating to reducing such 
incidental taking from such specified activities, and evaluating its 
effects.
    8. Applicants must develop and implement a site-specific (or 
umbrella plan addressing site-specific considerations), Service-
approved marine mammal monitoring and mitigation plan to monitor and 
evaluate the effectiveness of mitigation measures and the effects of 
activities on marine

[[Page 88226]]

mammals and the subsistence use of these species.
    9. Applicants must also provide trained, qualified, and Service-
approved onsite observers to carry out monitoring and mitigation 
activities identified in the marine mammal monitoring and mitigation 
plan.
    This information is necessary for the Service to anticipate the 
impact of the activity on the species or stocks and on the availability 
of the species or stocks for Alaska Native subsistence uses. Under 
requirements of the MMPA, we cannot authorize a take unless the total 
of all takes will have a negligible impact on the species or stocks 
and, where appropriate, will not have an unmitigable adverse impact on 
the availability of the species or stocks for subsistence uses. These 
requirements ensure that applicants are aware of related monitoring and 
research efforts they can apply to their situation, and that the 
monitoring and reporting that we impose are the least burdensome to the 
applicant.
    (B) Incidental Take of Marine Mammals--Requests for LOA--LOAs, 
which may be issued only to U.S. citizens, are required to conduct 
activities pursuant to any specific regulations established. Once 
specific regulations are effective, the Service will, to the maximum 
extent possible, process subsequent requests for LOAs within 30 days 
after receipt of the request by the Service. All LOAs will specify the 
period of validity and any additional terms and conditions appropriate 
for the specific request. Issuance of LOAs will be based on a 
determination that the level of taking will be consistent with the 
findings made for the total taking allowable under the specific 
regulations.
    (C) Incidental Take of Marine Mammals--Final Monitoring Report--The 
results of monitoring and mitigation efforts identified in the marine 
mammal monitoring and mitigation plan must be submitted to the Service 
for review within 90 days of the expiration of an LOA. Upon request, 
final report data must be provided in a common electronic format (to be 
specified by the Service). Information in the final (or annual) report 
must include, but is not limited to:
    1. Copies of all observation reports submitted under the LOA;
    2. A summary of the observation reports;
    3. A summary of monitoring and mitigation efforts including areas, 
total hours, total distances, and distribution;
    4. Analysis of factors affecting the visibility and detectability 
of walruses and polar bears during monitoring;
    5. Analysis of the effectiveness of mitigation measures;
    6. Analysis of the distribution, abundance, and behavior of 
walruses and/or polar bears observed; and
    7. Estimates of take in relation to the specified activities.
    (D) Polar Bear Den Detection Report--Holders of an LOA seeking to 
carry out onshore activities in known or suspected polar bear denning 
habitat during the denning season must make efforts to locate occupied 
polar bear dens within and near proposed areas of operation. They may 
use any appropriate tool, such as forward-looking infrared imagery and/
or polar bear scent-trained dogs, in concert with denning habitat maps 
along the Alaskan coast.
    1. In accordance with 50 CFR 18.128(b)(1) and (2), LOA holders must 
report all observed or suspected polar bear dens to us prior to the 
initiation of activities. We use this information to determine the 
appropriate terms and conditions in an individual LOA in order to 
minimize potential impacts and disturbance to polar bears.
    2. Holders of an LOA seeking to carry out onshore activities during 
the denning season (November-April) must conduct two separate surveys 
for occupied polar bear dens in all denning habitat within 1.6 km (1 
mi) of proposed activities using aerial infrared (AIR) imagery. 
Further, all denning habitat within 1.6 km (1 mi) of areas of proposed 
seismic surveys must be surveyed three separate times with AIR 
technology.
    3. Flight crews will record and report environmental parameters 
including air temperature, dew point, wind speed and direction, cloud 
ceiling, and percent humidity, and a flight log will be provided to the 
Service within 48 hours of the flight.
    (E) In-Season Monitoring--Activity Progress Reports--Holders of an 
LOA must:
    1. Notify the Service at least 48 hours prior to the onset of 
activities;
    2. Provide the Service weekly progress reports of any significant 
changes in activities and/or locations; and
    3. Notify the Service within 48 hours after ending of activities.
    (F) In-season Monitoring--Observation Reports--Holders of an LOA 
must report, within 48 hours, all observations of polar bears and 
potential polar bear dens, during any industry activity. Upon request, 
monitoring report data must be provided in a common electronic format 
(to be specified by the Service). Information in the observation report 
must include, but is not limited to:
    1. Date, time, and location of observation;
    2. Number of bears;
    3. Sex and age of bears (if known);
    4. Observer name and contact information;
    5. Weather, visibility, sea state, and sea-ice conditions at the 
time of observation;
    6. Estimated closest distance of bears from personnel and 
facilities;
    7. Industry activity at time of sighting;
    8. Possible attractants present;
    9. Bear behavior;
    10. Description of the encounter;
    11. Duration of the encounter; and
    12. Mitigation actions taken.
    (G) Notification of LOA Incident Report--Holders of an LOA must 
report, as soon as possible, but within 48 hours, all LOA incidents 
during any Industry activity. An LOA incident is any situation when 
specified activities exceed the authority of an LOA, when a mitigation 
measure was required but not enacted, or when injury or death of a 
marine mammal occurs. Reports must include:
    1. All information specified for an observation report;
    2. A complete detailed description of the incident; and
    3. Any other actions taken.
    (H) Mitigation--Interaction Plan--All holders of an LOA must have 
an approved polar bear safety, awareness, and interaction plan on file 
with the Service's Marine Mammals Management Office and onsite and 
provide polar bear awareness training to certain personnel. Interaction 
plans must include:
    1. The type of activity and where and when the activity will occur 
(i.e., a summary of the plan of operation);
    2. A food, waste, and other ``bear attractants'' management plan;
    3. Personnel training policies, procedures, and materials;
    4. Site-specific walrus and bear interaction risk evaluation and 
mitigation measures;
    5. Bear avoidance and encounter procedures; and
    6. Bear observation and reporting procedures.
    (I) Mitigation--3rd Party Notifications--All applicants for an LOA 
must contact affected Alaska Native subsistence communities and hunter 
organizations to discuss potential conflicts caused by the activities 
and provide the Service documentation of communications.
    (J) Mitigation--Requests for Exemption Waivers--Exemption waivers 
to the operating conditions in 50 CFR 18.126(c) may be issued by the

[[Page 88227]]

Service on a case-by-case basis, based upon a review of seasonal ice 
conditions and available information on walrus and polar bear 
distributions in the area of interest.
    (K) Mitigation--Plan of Cooperation--When appropriate, a holder of 
an LOA will be required to develop and implement a Service-approved 
plan of cooperation (POC).
    1. The POC must include a description of the procedures by which 
the holder of the LOA will work and consult with potentially affected 
Alaska Native subsistence hunters and a description of specific 
measures that have been or will be taken to avoid or minimize 
interference with subsistence hunting of otters, walruses, and polar 
bears and to ensure continued availability of the species for 
subsistence use.
    2. The Service will review the POC to ensure that any potential 
adverse effects on the availability of the animals are minimized. The 
Service will reject POCs if they do not provide adequate safeguards to 
ensure the least practicable adverse impact on the availability of 
walruses and polar bears for subsistence use.
    (2) Revise OMB Control No. 1018-0070 to remove references to, and 
all burden associated with, information collections (ICs) in 50 CFR 
part 18, subpart K--Cook Inlet, to include updating the title of this 
collection--The ITR in subpart K, issued to Hilcorp Alaska, LLC, 
Harvest Alaska, LLC, and the Alaska Gasline Development Corporation on 
August 1, 2019, authorized the nonlethal, incidental, but not 
intentional, take of small numbers of northern sea otters (Enhydra 
lutris kenyoni) for activities associated with or in support of oil and 
gas exploration, development, production, and transportation in Cook 
Inlet, Alaska. This ITR expired on August 1, 2024, and is no longer 
active; therefore, we are removing the reference to the ICR, along with 
the associated burden, from OMB Control No. 1018-0070.
    (3) Request a new control number for the currently approved ICs and 
burden estimates associated with 50 CFR part 18, subpart L--U.S. Coast 
Guard--We will submit a separate information collection request to OMB 
for approval that will contain the applicable ICs and associated burden 
for subpart L previously approved by OMB under OMB Control No. 1018-
0070. The ITR in subpart L, effective May 19, 2023, authorizes the 
nonlethal, incidental, unintentional take by harassment of small 
numbers of northern sea otters (otters; Enhydra lutris kenyoni) while 
engaged in activities associated with or in support of marine 
construction activities in the Gulf of Alaska. Unless a new ITR is 
issued for subpart L, we will discontinue the newly assigned control 
number when the ITR expires on May 19, 2028.
    We propose to transfer the following currently approved ICs from 
OMB Control No. 1018-0070 into a new control number:
    (A) Incidental Take of Marine Mammals--Application for 
Regulations--Regulations at 50 CFR part 18 require the applicant to 
provide information on the activity as a whole, which includes, but is 
not limited to, an assessment of total impacts by all persons 
conducting the activity. Applicants can find specific requirements in 
50 CFR part 18, subpart J. These regulations provide the applicant with 
a detailed description of information that we need to evaluate the 
proposed activity and determine whether to issue specific regulations 
and, subsequently, LOAs. The required information includes:
    1. A description of the specific activity or class of activities 
that can be expected to result in incidental taking of marine mammals.
    2. The dates and duration of such activity and the specific 
geographical region where it will occur.
    3. Based on the best available scientific information, each 
applicant must also provide:
    a. An estimate of the species and numbers of marine mammals likely 
to be taken by age, sex, and reproductive conditions;
    b. The type of taking (e.g., disturbance by sound, injury or death 
resulting from collision, etc.) and the number of times such taking is 
likely to occur;
    c. A description of the status, distribution, and seasonal 
distribution (when applicable) of the affected species or stocks likely 
to be affected by such activities;
    d. The anticipated impact of the activity upon the species or 
stocks; and
    e. The anticipated impact of the activity on the availability of 
the species or stocks for subsistence uses.
    4. The anticipated impact of the activity upon the habitat of the 
marine mammal populations and the likelihood of restoration of the 
affected habitat.
    5. The availability and feasibility (economic and technological) of 
equipment, methods, and manner of conducting such activity or other 
means of effecting the least practicable adverse impact upon the 
affected species or stocks, their habitat, and, where relevant, on 
their availability for subsistence uses, paying particular attention to 
rookeries, mating grounds, and areas of similar significance. (The 
applicant and those conducting the specified activity and the affected 
subsistence users are encouraged to develop mutually agreeable 
mitigating measures that will meet the needs of subsistence users.)
    6. Suggested means of accomplishing the necessary monitoring and 
reporting that will result in increased knowledge of the species 
through an analysis of the level of taking or impacts and suggested 
means of minimizing burdens by coordinating such reporting requirements 
with other schemes already applicable to persons conducting such 
activity.
    7. Suggested means of learning of, encouraging, and coordinating 
research opportunities, plans, and activities relating to reducing such 
incidental taking from such specified activities, and evaluating its 
effects.
    8. Applicants must develop and implement a site-specific (or 
umbrella plan addressing site-specific considerations), Service-
approved marine mammal monitoring and mitigation plan to monitor and 
evaluate the effectiveness of mitigation measures and the effects of 
activities on marine mammals and the subsistence use of these species.
    9. Applicants must also provide trained, qualified, and Service-
approved onsite observers to carry out monitoring and mitigation 
activities identified in the marine mammal monitoring and mitigation 
plan.
    This information is necessary for the Service to anticipate the 
impact of the activity on the species or stocks and on the availability 
of the species or stocks for Alaska Native subsistence uses. Under 
requirements of the MMPA, we cannot authorize a take unless the total 
of all takes will have a negligible impact on the species or stocks 
and, where appropriate, will not have an unmitigable adverse impact on 
the availability of the species or stocks for subsistence uses. These 
requirements ensure that applicants are aware of related monitoring and 
research efforts they can apply to their situation, and that the 
monitoring and reporting requirements that we impose are the least 
burdensome to the applicant.
    (B) Incidental Take of Marine Mammals--Requests for LOA--LOAs, 
which may be issued only to U.S. citizens, are required to conduct 
activities pursuant to any specific regulations established. Once 
specific regulations are effective, the Service will, to the maximum 
extent possible, process subsequent requests for LOAs within 30 days 
after receipt of the request by the Service. All LOAs will

[[Page 88228]]

specify the period of validity and any additional terms and conditions 
appropriate for the specific request. Issuance of LOAs will be based on 
a determination that the level of taking will be consistent with the 
findings made for the total taking allowable under the specific 
regulations.
    (C) Incidental Take of Marine Mammals--Final Monitoring Report--The 
results of monitoring and mitigation efforts identified in the marine 
mammal monitoring and mitigation plan must be submitted to the Service 
for review within 90 days of the expiration of an LOA. Upon request, 
final report data must be provided in a common electronic format (to be 
specified by the Service). Information in the final (or annual) report 
must include, but is not limited to:
    1. A summary of monitoring efforts (hours of monitoring, activities 
monitored, number of protected species observers (PSOs), and, if 
requested by the Service, the daily monitoring logs).
    2. A description of all project activities, along with any 
additional work yet to be done. Factors influencing visibility and 
detectability of otters (e.g., sea state, number of observers, and fog 
and glare) will be discussed.
    3. A description of the factors affecting the presence and 
distribution of sea otters (e.g., weather, sea state, and project 
activities). An estimate will be included of the number of sea otters 
exposed to noise at received levels greater than or equal to 160 dBRMS 
re: 1 [micro]Pa (decibels root-mean squared referenced to 1 
microPascal) (based on visual observation).
    4. A description of changes in sea otter behavior resulting from 
project activities and any specific behaviors of interest.
    5. A discussion of the mitigation measures implemented during 
project activities and their observed effectiveness for minimizing 
impacts to sea otters. Sea otter observation records will be provided 
to the Service in the form of electronic database or spreadsheet files.
    (D) In-Season Monitoring--Activity Progress Reports--Holders of an 
LOA must:
    1. Notify the Service at least 48 hours prior to the onset of 
activities;
    2. Provide the Service weekly progress reports of any significant 
changes in activities and/or locations;
    3. Injured, dead, or distressed sea otters that are not associated 
with project activities (e.g., animals known to be from outside the 
project area, previously wounded animals, or carcasses with moderate to 
advanced decomposition or scavenger damage) must be reported to the 
Service within 24 hours of the discovery to either the Service MMM (1-
800-362-5148, business hours); or the Alaska SeaLife Center in Seward 
(1-888-774-7325, 24 hours a day); or both. Photographs, video, location 
information, or any other available documentation must be provided to 
the Service.
    4. Notify the Service within 48 hours after ending of activities.
    (E) In-season Monitoring--Observation Reports--Holders of an LOA 
must report, within 48 hours, all observations of polar bears and 
potential polar bear dens, during any Industry activity. Upon request, 
monitoring report data must be provided in a common electronic format 
(to be specified by the Service). Information in the observation report 
must include, but is not limited to:
    1. Date, time; the observer's locations, heading, and speed (if 
moving); weather; visibility; number of animals; group size and 
composition (adults/juveniles); and the location of the animals (or 
distance and direction from the observer);
    2. Initial behaviors of the sea otters, descriptions of project 
activities and underwater sound levels being generated, the position of 
sea otters relative to applicable monitoring and mitigation zones, any 
mitigation measures applied, and any apparent reactions to the project 
activities before and after mitigation;
    3. Distance from the vessel to the sea otter upon initial 
observation, the duration of the encounter, and the distance at last 
observation in order to monitor cumulative sound exposures; and
    4. Any instances of animals lingering close to or traveling with 
vessels for prolonged periods of time.
    (F) Notification of LOA Incident Report--Holders of an LOA must 
report, as soon as possible, but within 48 hours, all LOA incidents 
during any Industry activity. An LOA incident is any situation when 
specified activities exceed the authority of an LOA, when a mitigation 
measure was required but not enacted, or when injury or death of a 
marine mammal occurs. Reports must include:
    1. All information specified for an observation report;
    2. A complete detailed description of the incident; and
    3. Any other actions taken.
    (G) Mitigation--Interaction Plan--All holders of an LOA must have 
an approved polar bear safety, awareness, and interaction plan on file 
with the Service's Marine Mammals Management Office and onsite and 
provide polar bear awareness training to certain personnel. Interaction 
plans must include:
    1. The type of activity and where and when the activity will occur 
(i.e., a summary of the plan of operation);
    2. Personnel training policies, procedures, and materials;
    3. Site-specific sea otter interaction risk evaluation and 
mitigation measures;
    4. Sea otter avoidance and encounter procedures; and
    5. Sea otter observation and reporting procedures.
    (H) Mitigation--3rd Party Notifications--All applicants for an LOA 
must contact affected Alaska Native subsistence communities and hunter 
organizations to discuss potential conflicts caused by the activities 
and provide the Service documentation of communications.
    (I) Mitigation--Requests for Exemption Waivers--Exemption waivers 
to the operating conditions in 50 CFR 18.126(c) may be issued by the 
Service on a case-by-case basis, based upon a review of seasonal ice 
conditions and available information on marine mammal distributions in 
the area of interest.
    (J) Mitigation--Plan of Cooperation--When appropriate, a holder of 
an LOA will be required to develop and implement a Service-approved 
plan of cooperation (POC).
    1. The POC must include a description of the procedures by which 
the holder of the LOA will work and consult with potentially affected 
subsistence hunters and a description of specific measures that have 
been or will be taken to avoid or minimize interference with 
subsistence hunting of marine mammals and to ensure continued 
availability of the species for subsistence use.
    2. The Service will review the POC to ensure that any potential 
adverse effects on the availability of the animals are minimized. The 
Service will reject POCs if they do not provide adequate safeguards to 
ensure the least practicable adverse impact on the availability of 
marine mammals for subsistence use.

Energy Effects

    Executive Order 13211 requires agencies to prepare statements of 
energy effects when undertaking certain actions. This proposed rule 
provides exceptions from the MMPA's taking prohibitions for Industry 
engaged in specified oil and gas activities in the specified geographic 
region. By providing certainty regarding compliance with the MMPA, this 
proposed rule would have a positive effect on Industry and its 
activities. Therefore, this proposed rule is not expected to 
significantly affect energy supplies, distribution, or use and does not 
constitute a significant energy action. No statement of energy effects 
is required.

Proposed Regulation Promulgation

    For the reasons set forth in the preamble, the Service proposes to 
amend part 18, subchapter B of chapter I, title 50 of the Code of 
Federal Regulations as set forth below:

PART 18--MARINE MAMMALS

1. The authority citation of part 18 continues to read as follows:

    Authority:  16 U.S.C. 1361 et seq.


Sec.  18.4   [Removed]

0
2. Remove Sec.  18.4.
0
3. Revise Sec.  18.124 to read as follows:


Sec.  18.124   Authorized take allowed under a Letter of Authorization 
(LOA).

    (a) An LOA allows for the nonlethal, non-injurious, incidental, but 
not intentional take by Level B harassment, as defined in Sec.  18.3 
and under section 3 of the Marine Mammal Protection Act (16 U.S.C. 
1362), of Pacific walruses while conducting oil and gas industry 
exploration, development, and production within the Beaufort Sea ITR 
region described in Sec.  18.120.
