[COE-2018-0005]


Pacific Ocean at Naval Base Guam Telecommunication Site, 
Finegayan Small Arms Range, on the Northwestern Coast of Guam; Danger 
Zone

AGENCY: U.S. Army Corps of Engineers, DoD.

ACTION: Final rule.

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

SUMMARY: The Corps of Engineers (Corps) is amending its danger zone 
regulations to establish a danger zone in the Pacific Ocean adjacent to 
the existing Finegayan Small Arms Range at Naval Base Guam 
telecommunication site on the northwestern coast of Guam. The danger 
zone is located entirely within the Pacific Ocean, comprising 892 acres 
and extending 2.36 miles into the ocean from the high tide line. 
Establishment of the danger zone will intermittently prohibit vessels 
from lingering in the danger zone when the small arms range is in 
active use in order to ensure public safety.

DATES: Effective August 19, 2020.

ADDRESSES: U.S. Army Corps of Engineers, Attn: CECW-CO (David Olson), 
441 G Street NW, Washington, DC 20314-1000.

FOR FURTHER INFORMATION CONTACT: Mr. David Olson, Headquarters, 
Operations and Regulatory Division, at [email protected] or 
202-761-4922.

SUPPLEMENTARY INFORMATION: In response to a request by the United 
States Navy, and pursuant to its authorities in Section 7 of the Rivers 
and Harbors Act of 1917 (40 Stat. 266; 33 U.S.C. 1) and Chapter XIX of 
the Army Appropriations Act of 1919 (40 Stat. 892; 33 U.S.C. 3), the 
Corps of Engineers (Corps) is amending its danger zone regulations to 
establish a permanent danger zone in the Pacific Ocean adjacent to the 
Finegayan Small Arms Range (FSAR) on Guam. The danger zone will be 
added at 33 CFR 334.1415. The danger zone is needed for the Department 
of Defense to meet its mission under 10 U.S.C. 5062, which is to 
maintain, train, and equip combat-ready military forces, deterring 
aggression, and maintaining freedom of the seas. Due to the strategic 
location of Guam and the Department of Defense's ongoing reassessment 
of the Western Pacific military alignment, there has been an increase 
in the importance of the FSAR as a training and testing venue. The 
danger zone is necessary to protect the public from hazards associated 
with small arms training.
    The proposed rule was published in the Federal Register on December 
13, 2018 (83 FR 64053). The regulations.gov docket number was COE-2018-
0005. Concurrently, a local public notice for the proposed danger zone 
was sent out from the Honolulu District. In response to the proposed 
rule, 45 comments were received. The comments are summarized below, 
with the Corps' responses to those comments.
    Several commenters requested a time extension for the public 
comment period. Twenty-two commenters requested either a public hearing 
with the Corps or public meetings with representatives of the Navy and/
or Corps. The commenters requested these meetings to better understand 
the impacts of the FSAR and the proposed danger zone, and to have an 
open dialogue and discussion.
    The Corps determined that 30 days was sufficient to provide 
comments on the proposed danger zone regulation. The Corps' regulations 
at 33 CFR part 327 allow district engineers to conduct public hearings 
for the purpose of acquiring information which will be considered in 
evaluating a proposed action that requires a decision by the Corps. A 
public hearing gives the public an opportunity to present their views, 
opinions, and information on a proposed action. The district engineer 
has the discretion to not hold a public hearing if he or she determines 
that there would be no valid interest to be served by a public hearing, 
or a public hearing would not result in interested parties presenting 
information that could not be provided to the Corps via comments 
submitted in response to a proposed rule or a proposed permit action. 
The Corps district carefully reviewed all of the requests for a public 
hearing or public meetings, as well as the comments received in 
response to the proposed rule, and concluded that a public hearing 
would not identify issues or concerns that were not already identified 
and discussed in the comments submitted in response to the proposed 
rule and the district's public notice. Therefore, the district engineer 
decided not to hold any public hearings or public meetings for this 
proposed rule.
    A couple of commenters requested the Corps prepare an environmental 
impact statement (EIS) for the proposed rule. Several commenters 
expressed concerns with the 2010 Mariana Islands Range Complex 
Environmental Impact Statement/Overseas Environmental Impact Statement 
and the 2015 Mariana Islands Training and Testing Environmental Impact 
Statement/Overseas Environmental Impact Statement and compliance with 
federal laws, including the Coastal Zone Management Act, the Magnuson-
Stevens Fishery Conservation and Management Act, the Endangered Species 
Act, and the National Historic Preservation Act. Some commenters 
requested that additional studies be conducted, as well as additional 
assessments of the impacts, to better understand the effects of the 
Mariana Islands Range Complex and training activities on natural 
resources, historical and cultural resources, the economy, and to the 
people of Guam. One commenter said that specific sections of these EIS 
documents should be referenced and stated the public notice, or the 
public notice should be considered incomplete. Several commenters 
requested a review of

[[Page 43689]]

cumulative impacts. One commenter asked how the proposed danger zone 
relates to the future Marine Corps base. One commenter wanted to know 
how the Corps will mitigate any impacts to the environment.
    For the purposes of the National Environmental Policy Act (NEPA), 
the federal action being undertaken by the Corps is the promulgation of 
the danger zone regulation under its authorities at 33 U.S.C. 1 and 3 
and the procedures in 33 CFR part 334. The Corps is responsible for 
assessing the impacts of the proposed danger zone on the human 
environment, and for preparing appropriate NEPA documentation for its 
decision on whether to issue the final rule for the danger zone. To 
comply with NEPA requirements, the Corps prepared an environmental 
assessment for this rulemaking action and concluded that the 
establishment of the danger zone would not have a significant impact on 
the quality of the human environment and therefore does not require the 
preparation of an EIS. A copy of the environmental assessment is 
available from the Corps district office. The establishment of this 
danger zone would not result in work, structures, or construction 
within the Pacific Ocean, or any modification to any vegetation, 
habitat, or structures in the Pacific Ocean, on the shore, or on the 
land. Therefore, it will not have any impacts on natural resources or 
historical and cultural resources. With respect to impacts to people on 
Guam, the danger zone is intended to protect the public from hazards 
that may result from the use of the FSAR at the Naval Base Guam 
telecommunication site. The boundaries of the danger zone will be 
plotted by National Oceanic and Atmospheric Administration on its 
nautical charts, which will help alert users of those navigable waters 
to the danger zone.
    For the establishment and operation of the FSAR itself, the Navy is 
the Federal agency responsible for compliance with applicable federal 
laws, which may include Section 7 of the Endangered Species Act, the 
Essential Fish Habitat provisions of the Magnuson-Stevens Fishery 
Conservation and Management Act, Section 106 of the National Historic 
Preservation Act, and the Coastal Zone Management Act. The Navy's 
documents demonstrating compliance with these laws and concurrences 
from the agencies administering these laws can be obtained from the 
Marianas Islands Training and Testing website at https://mitt-eis.com.
    Cumulative impacts were evaluated in the environmental assessment 
prepared by the Corps district for this final rule. The establishment 
of a future Marine Corps base on Guam is a separate action that is 
outside of the Corps' rulemaking action for the establishment of this 
danger zone. Therefore, the Corps is not required address that 
potential future action in its NEPA documentation. Since the danger 
zone will be in effect only when the FSAR is in use and the 
establishment of the danger zone will promote public safety and will 
not have any physical environmental effects, impacts to the human 
environment have been minimized. The Corps has determined there is no 
need or requirement for mitigation beyond incorporating into the rule 
text measures to minimize impacts to maritime traffic and fishing 
activities.
    Multiple commenters expressing concern about potential impacts of 
the danger zone on Guam's fishing industry. Multiple individuals 
provided comments about impacts to commercial tourism operations, 
subsistence fishing, and recreational fishing. One commenter stated 
that the danger zone would create additional restrictions to 
subsistence and artisanal fishers. Several commenters wanted to better 
understand how the establishment of a danger zone would impact the 
movement of the fishing community up and down the coast, and whether 
fishermen would be forced to move into less safe waters outside the 
danger zone. Many commenters wanted to know how often access to the 
proposed danger zone would be restricted.
    The Corps' regulations require that danger zones and restricted 
areas provide public access to the area to the maximum extent 
practicable and not cause unreasonable interference with or restrict 
the food fishing industry (see 33 CFR 334.3(a) and (b), respectively). 
The regulations require the Corps to consult with the Regional 
Directors of the U.S. Fish and Wildlife Service and National Marine 
Fisheries Service regarding impacts to the food fishing industry. The 
Corps district sent each agency a letter dated May 6, 2019, requesting 
comments in relation to the food fishing industry. Neither agency 
responded to those letters.
    The establishment of a danger zone would intermittently restrict 
commercial, public, and private vessels from entering or lingering in 
the danger zone to ensure public safety during small arms training 
activities at the FSAR. Although the danger zone would restrict use of 
the waters within its boundaries while the small arms range is in use, 
it would not restrict access through the danger zone to fishing grounds 
to the north or south. While the small arms range is in use, the Navy 
would halt training activities to allow vessels to expeditiously 
transit through the danger zone. When the range is not in use, the 
waters within the danger zone boundaries would be open to fishing.
    Upon establishment of the danger zone, nautical charts will be 
updated to identify the boundaries of the danger zone for mariner 
awareness and route planning. A Notice to Mariners will also be issued 
each time the range is active. The Corps has determined that the Navy 
has provided for public access to the area to the maximum extent 
practicable. Additionally, the Corps has determined, based on the Navy 
allowing fishing vessels to transit through the danger zone, that there 
will not be unreasonable interference or restrictions to the food 
fishing industry.
    The Corps received multiple comments about the impacts of the 
danger zone to recreation and access, including impacts to the native 
Chamorro population as well as tourism operations. Several people 
wanted to know if the restrictions associated with the danger zone 
would result in economic impacts. Some commenters expressed concern 
about how the danger zone may affect local property owners.
    The Corps' regulations state that danger zone regulations shall 
provide for public access to the area to the maximum extent 
practicable. This danger zone will intermittently restrict commercial, 
public, and private vessels from entering or lingering in the danger 
zone to ensure public safety during small arms training activities. 
Although the danger zone would restrict use of the waters within its 
boundaries while the small arms range is in use, it would not restrict 
access through the danger zone to areas north or south. While the small 
arms range is in use, the Navy would halt training activities to allow 
vessels to expeditiously transit through the danger zone. When the 
range is not in use, the danger zone would be open to normal maritime 
activities. Therefore, it will only have intermittent impacts on 
recreation and access for the public, including the native Chamorro 
population. Based on previous operations of the FSAR, the Corps has 
determined that the establishment of the danger zone regulation would 
have no economic impact on Guam's tourism industry or cruise vessel 
operations. The danger zone is located completely in the waters of the 
Pacific Ocean. The Corps has determined that the establishment of the 
danger zone would cause no disruption in access to homes or businesses.

[[Page 43690]]

    Multiple commenters expressed concerns about potential effects to 
cultural and historical resources. Several commenters expressed their 
belief that Chamorro cultural values and practices would be jeopardized 
by the proposed establishment of the danger zone. Several commenters 
wanted to know if the range would limit access to ancient and sacred 
historical sites that are regularly visited by the Chamorro people. One 
commenter wanted to know if the danger zone would have any implications 
on the ``2011 Programmatic Agreement'' and whether public access to 
Haputo Reef, Double Reef, and Tweed's Cave would be affected by the 
proposed danger zone. Others provided information about the existing 
cultural and historic sites near the FSAR. Several others had specific 
questions about how it would affect traditional fishing grounds. A 
couple of individuals asserted that Chamorro traditional fishing 
grounds should not be inaccessible to the Chamorro people. One 
commenter wanted to know how the danger zone would affect Chamorro 
medicinal plant and coconut crab collecting practices.
    The danger zone restricts the use of navigable waters to protect 
the public during small arms training activities. It does not involve 
any actions that have the potential to cause effects to historic 
properties, cultural resources, or sacred cultural sites. There would 
be no construction, structures, or in-water work associated with the 
establishment of the danger zone. The Corps acknowledges that there may 
be temporary disruptions to accessing traditional fishing grounds when 
the range is in use and has determined that these disruptions would be 
minimal, and are necessary for safety. When the range is not in use, 
the danger zone will be open and the waters available to public water 
users.
    The danger zone is not associated with the 2011 Programmatic 
Agreement. Public access to Haputo Beach, Double Reef, and Tweed's cave 
is available via the Joint Region Marianas Public Access Plan for 
Historic and Cultural Sites when the range is not in use. In addition, 
coconut crab collection is not authorized on Department of Defense 
property.
    Multiple commenters voiced concerns about potential effects to 
upland and in-water plants and animals in and adjacent to the danger 
zone, including the fruit bat, fish, corals, sea turtles, and other 
aquatic species. Several commenters expressed concerns about potential 
impacts to threatened and endangered species and Essential Fish 
Habitat. One commenter wanted to know if the danger zone would 
negatively impact the presence and propagation of coconut trees or any 
other endemic or native plants and trees.
    The establishment of the danger zone will not result in a 
modification to any vegetation, habitat, or structures in the Pacific 
Ocean, on the shore, or on the land. Establishment of the danger zone 
will not have any effect on land-based plants and animals. If humans 
are not able to loiter in the danger zone while the firing range is 
operational, then there may be less human impact on marine ecosystems 
within the boundaries of the danger zone. Therefore, the restrictions 
imposed by the establishment of the danger zone are likely to have 
negligible or mildly beneficial impacts on marine life. The 
establishment of the danger zone will have no effect on marine species 
and habitat, including coral species, listed under the Endangered 
Species Act and it will have no adverse effect on Essential Fish 
Habitat. Although the Corps has the authority to establish danger zones 
to protect the public from potential dangers imposed by target 
practice, bombing, rocket firing or other especially hazardous 
operations, the Corps does not regulate boating activities in general, 
and does not have the authority to control environmental effects that 
may be caused by boating activities.
    The Corps received comments expressing concern about the safety 
risks associated with the operation of the danger zone. A couple of 
commenters wanted more information about how the limits of the firing 
range, extending into the ocean up to 2.36 nautical miles from the 
shore, were determined. A couple of commenters inquired about the 
efficacy of the red flag and strobe light. One commenter asked if the 
red flag that would be used to communicate with mariners during the 
daytime and strobe light that would be used to communicate with 
mariners during the nighttime could be seen under all weather 
conditions in the entirety of the proposed danger zone. A commenter 
wanted to know what other methods of alerting the public that the 
firing range was in use were considered. One commenter asked if 
fishermen could be notified in advance to help better plan their trip. 
One individual inquired about installing a warning system at Gregorio 
D. Perez Marina where most boaters launch.
    The danger zone boundaries were established to include all areas 
where a potential hazard exists for a projectile not being contained by 
the earthen berms at the FSAR, although this type of event has a very 
low probability of occurring. Danger zones are established for this 
reason to ensure safe range operations. The parameters of the danger 
zone were determined by the maximum distance a small arms round can 
travel. The Navy has no plans to expand the footprint of the existing 
ranges, increase weapons caliber, or use these ranges for bombing, 
rocket firing, or other especially hazardous operations. Targets would 
not be placed within the danger zone. These ranges would continue to be 
used in the same capacity as they were used since the 1970s.
    Similar to navigation lights/aids on buoys and approach lighting 
for airfields, the strobe light (nighttime), would be visible under all 
weather conditions that would be conducive to small boat and small arms 
range operations. The red flag (daytime) method of identifying an 
active danger zone is currently in use at the Naval Base Guam Known 
Distance and Multi-Purpose Ranges and has proven to be an effective 
method of alerting the public of small arms range operation. The red 
flag and strobe light were the only methods of alerting the public that 
were considered by the Navy. The strobe light was added for the FSAR as 
an additional method of alerting the public during nighttime operations 
of the range. The red flag and strobe light have been proven effective 
in alerting the public and have been proven as feasible methods of 
identifying the danger zones as being active. It should also be noted 
that an added measure of safety is taken in that small arms range 
operating procedures require a lookout to be present during range 
operations as a positive means to verify the danger zone is clear. If a 
fisherman or other vessel inadvertently enters the danger zone area, 
range operations would cease until the danger zone is clear. In 
addition, small arms range operating procedures require specially 
qualified range supervisors and operators to oversee small arms range 
operations. These specially qualified personnel ensure all small arms 
range safety procedures are followed and provide an added layer of 
safety to prevent errant bullets from leaving the confines of the small 
arms range berms.
    A Notice to Mariners will be issued each time the range is active. 
These notices are issued to notify mariners that an established danger 
zone is active. In addition, after this final rule is issued, nautical 
charts will be updated by the National Oceanic and Atmospheric 
Administration's Office of Coast Survey to identify the boundaries of 
the danger zone for mariner

[[Page 43691]]

awareness and route planning. Due to the many safety layers and 
advanced notification actions mentioned above, which have been proven 
effective, the Navy is not planning a warning system located at 
Gregorio D. Perez Marina.
    Multiple commenters expressed concern with the potential for the 
firing range and danger zone to contribute to contamination of the air 
and water. Specific concerns included the introduction of lead, 
antimony, copper, zinc, nickel, arsenic, and other contaminants into 
the environment that could pose an environmental or human health 
threat. One commenter wanted to know if contaminants from the danger 
zone would impact the Haputo Ecological Reserve.
    The establishment of a danger zone in the Pacific Ocean adjacent to 
the FSAR is an administrative procedure that restricts navigable access 
to a portion of the ocean during small arms training activities to 
protect public safety. There will be no construction, structures or in-
water work associated with the establishment of the danger zone. The 
establishment of the danger zone by the Corps will not result in the 
release of contaminants. The operation of the FSAR itself, including 
the potential environmental impacts caused by rounds fired from the 
FSAR, falls outside of the Corps' regulatory authorities. Activation of 
the danger zone itself during small arms training activities would not 
result in any physical effects to air or water quality, or any physical 
effects to Haputo Ecological Reserve.
    Several commenters expressed concerns about erosion, accretion, and 
noise associated with the danger zone. One commenter asked whether the 
danger zone would violate the conditions to the 1983 Memorandum of 
Understanding with the Government of Guam that created the Haputo 
Ecological Reserve.
    The establishment of the danger zone involves no construction, 
structures or in-water work associated with the establishment of the 
danger zone. Therefore, the establishment of this danger zone will not 
affect erosion, accretion, or noise. In compliance with the Coastal 
Zone Management Act, the 1983 Memorandum of Understanding committed the 
Navy to the establishment of two Ecological Reserve Areas (ERAs) as 
mitigation for the adverse environmental impacts anticipated to accrue 
from the construction of an ammunition wharf at Adotgan Point in outer 
Apra Harbor, what has since become known as Kilo Wharf. The two ERAs to 
be established were the Orate Peninsula Cliff ERA and the Haputo ERA. 
While there were several conditions associated with the establishment 
of the Orate Peninsula ERA, none were established for the Haputo ERA 
aside from the requirement to take ``all possible measures'' to 
``preserve its quality for the people of Guam, now and for the 
future.'' It was further stipulated that ``it be protected from 
development of any kind and from the taking or destruction of its 
natural and historic resources.'' At the time the ERA was designated, 
the FSAR had been in existence for nearly a decade, and it has operated 
since with little change in frequency or manner of use. There are no 
changes in the size, location, operation of the range, the type of 
small arms utilized, or the tempo of operations being proposed. As a 
result, the establishment of the danger zone would not violate the 
conditions of the 1983 Memorandum of Understanding with the Government 
of Guam that created the Haputo ERA.
    Multiple commenters asked whether there are practicable 
alternatives to the establishment of a danger zone and what 
alternatives were evaluated. A couple commenters asked if there were 
upland alternatives or if private land or private ranges could be used. 
One commenter asked if a system could be designed or constructed to 
prevent ammunition from entering the area of the proposed danger zone 
whereby a danger zone would not be necessary.
    The FSAR has been in existence since 1975, and the establishment of 
this danger zone is necessary to protect the public during small arms 
training activities. It was not necessary to evaluate alternative sites 
because the danger zone is needed at this particular site. As discussed 
above, the boundaries of the danger zone were established to address 
the potential area where a small arms projectile could travel, to 
protect the public during small arms training exercises.

Procedural Requirements

    a. Regulatory Planning and Review. Executive Orders 12866 and 13563 
direct agencies to assess the costs and benefits of available 
regulatory alternatives and, if regulation is necessary, to select 
regulatory approaches that maximize net benefits. Executive Order 13771 
directs agencies to control regulatory costs through a budgeting 
process. For the reasons stated below, this final rule is not a 
``significant regulatory action'' under Executive Order 12866. 
Accordingly, this final rule has not been reviewed by the Office of 
Management and Budget (OMB), and pursuant to OMB guidance it is exempt 
from the requirements of Executive Order 13771.
    The Corps determined this final rule is not a significant 
regulatory action. This regulatory action determination is based on the 
rule text governing the danger zone, which allows any vessel that needs 
to transit the danger zone to expeditiously transit through the danger 
zone when the small arms range is in use. When the range is not in use, 
the danger zone will be open to normal maritime traffic and to all 
activities, include anchoring and loitering.
    b. Review Under the Regulatory Flexibility Act. This rule has been 
reviewed under the Regulatory Flexibility Act (Pub. L. 96-354). The 
Regulatory Flexibility Act generally requires an agency to prepare a 
regulatory flexibility analysis of any rule subject to notice-and-
comment rulemaking requirements under the Administrative Procedure Act 
or any other statute unless the agency certifies that the rule will not 
have a significant economic impact on a substantial number of small 
entities (i.e., small businesses and small governments). The danger 
zone is necessary to protect public safety during use of the small arms 
range. To minimize impacts to maritime traffic, the Navy will stop 
firing when the range is in use to allow vessels to transit through the 
danger zone. When the range is not in use, the danger zone will be open 
to normal maritime traffic and all activities, including anchoring and 
loitering. After considering the economic impacts of this danger zone 
regulation on small entities, I certify that this action will not have 
a significant economic impact on a substantial number of small 
entities.
    c. Review Under the National Environmental Policy Act. An 
environmental assessment (EA) has been prepared for the establishment 
of this danger zone. The Corps has concluded that the establishment of 
the danger zone will not have a significant impact to the quality of 
the human environment and, therefore, preparation of an EIS is not 
required. The final EA and Finding of No Significant Impact may be 
reviewed at the District Office listed at the FOR FURTHER INFORMATION 
CONTACT section, above.
    d. Unfunded Mandates Act. This rule does not impose an enforceable 
duty among the private sector and, therefore, it is not a Federal 
private sector mandate and it is not subject to the requirements of 
either Section 202 or Section 205 of the Unfunded Mandates Act. We have 
also found under Section 203 of the Act, small governments will not be 
significantly and uniquely affected by this rulemaking.

[[Page 43692]]

    e. Congressional Review Act. The Congressional Review Act, 5 U.S.C. 
801 et seq., generally provides that before a rule may take effect, the 
agency promulgating the rule must submit a rule report, which includes 
a copy of the rule, to each House of the Congress and to the 
Comptroller General of the United States. The Corps will submit a 
report containing the final rule and other required information to the 
U.S. Senate, the U.S. House of Representatives, and the Comptroller 
General of the United States. A major rule cannot take effect until 60 
days after it is published in the Federal Register. This final rule is 
not a ``major rule'' as defined by 5 U.S.C. 804(2).
