14 CFR Part 39

[Docket No. FAA-2023-0668; Project Identifier AD-2023-00199-R]
RIN 2120-AA64

Airworthiness Directives; Various Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive 2021-23-
13, which applies to all helicopters equipped with a radio (also known
as radar) altimeter. AD 2021-23-13 requires revising the limitations
section of the existing rotorcraft flight manual (RFM) for your
helicopter to incorporate limitations prohibiting certain operations
requiring radio altimeter data when in the presence of 5G C-Band
interference in areas as identified by Notices to Air Missions
(NOTAMs). Since the FAA issued AD 2021-23-13, the FAA determined that
additional limitations are needed due to the continued deployment of
new 5G C-Band base stations whose signals are expected to cover most of
the contiguous United States at transmission frequencies between 3.7-
3.98 GHz. This proposed AD would require revising the limitations
section of the existing RFM to incorporate limitations prohibiting
certain operations requiring radio altimeter data, due to the presence
of 5G C-Band interference. The FAA is proposing this AD to address the
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by May 12,
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

not specifically designated as CBI will be placed in the public docket
for this rulemaking.

Background

    The FAA issued Airworthiness Directive (AD) 2021-23-13, Amendment
39-21811 (86 FR 69992, December 9, 2021) (AD 2021-23-13), for all
helicopters equipped with a radio altimeter. AD 2021-23-13 was prompted
by a determination that radio altimeters cannot be relied upon to
perform their intended function if they experience interference from
wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-
Band). AD 2021-23-13 requires revising the limitations section of the
existing RFM to incorporate limitations prohibiting certain operations
requiring radio altimeter data when in the presence of 5G C-Band
interference as identified by NOTAMs. The agency issued AD 2021-23-13
because radio altimeter anomalies that are undetected by the automation
or pilot, particularly close to the ground, could lead to loss of
continued safe flight and landing.
    On the same day, the FAA also issued AD 2022-23-12, Amendment 39-
21810 (86 FR 69984, December 9, 2021) (AD 2021-23-12), to correct the
same unsafe condition on, and require similar operating limitations
for, all transport and commuter category airplanes equipped with a
radio altimeter.

Actions Since AD 2021-23-13

    Rotorcraft Capability and Alterations: Since issuing AD 2021-23-13
and AD 2021-23-12, the FAA has reviewed data from alternative method of
compliance (AMOC) requests, demonstrating that these radio altimeters
can be relied upon to perform their intended function when operating
beyond a certain protection radius around 5G C-Band transmitters. The
iterative AMOC process allowed the FAA to gain insight into 5G C-Band
transmission impacts in a progressively more sophisticated manner. At
first, the FAA made conservative assumptions about the potential for
impact on radio altimeters from 5G C-Band transmissions and applied
them to all airspace. During the FAA's initial analyses of AMOC
requests, the FAA looked to protect against 5G C-Band interference
during critical operations that rely on radio altimeters, by
prohibiting these operations within the vicinity of known 5G C-Band
emitters. After some time and an improved understanding of the 5G C-
Band signals and their effects on specific radio altimeters, the FAA
was able to reduce the protected area around the 5G C-band emitters to
protect rotorcraft.
    The FAA received and reviewed many more AMOC proposals from
transport category airplane operators for AD 2021-23-12 than from
helicopter operators for AD 2021-23-13. Some of the radio altimeters
used on rotorcraft are the same model as, or similar to, the radio
altimeters installed on transport category airplanes. As a result, the
AMOC process for AD 2021-23-12 and AD 2021-23-13 also provided data
about the varying levels of interference tolerance for a majority of
radio altimeters on the market, allowing the FAA to understand the
overall susceptibility to interference of the existing fleet of
rotorcraft. In addition, the FAA learned about the aircraft alterations
that can be accomplished quickly to improve a radio altimeter's
tolerance to transmissions in adjacent or nearby spectrum bands. Now
that the FAA better understands the performance of specific radio
altimeters and the means to make them more tolerant of transmissions in
adjacent or nearby spectrum bands, the FAA is proposing to retain the
existing prohibitions in AD 2021-23-13 with an option to upgrade to a
radio altimeter tolerant rotorcraft to avoid the prohibitions.
    5G Compatibility: AMOCs allowing operations otherwise prohibited by
AD 2021-23-13 were based on voluntary operational mitigations
undertaken by AT&T and Verizon, 5G C-Band licensees. The FAA, AT&T, and
Verizon have collaborated extensively to ensure 5G C-Band radio
frequency transmissions and rotorcraft operations can safely co-exist.
In early January 2022, the FAA progressively tailored runway safety
zones around airports to envelop only the airspace areas where critical
phases of flight occur. Although these tailored runway safety zones
around airports primarily benefited transport and commuter airplane
operations, they also benefited rotorcraft operating at those airports.
This collaborative work has allowed safe rotorcraft operations to
continue in the short term.
    Update to Safety Determination: The FAA's initial determination
that radio altimeters cannot be relied upon to perform their intended
function if they experience interference from wireless broadband
operations in the 5G C-Band remains unchanged. Unlike the Terrain
Awareness and Warnings Systems (TAWS) in transport airplanes, most
Helicopter Terrain Avoidance Warning Systems (HTAWS) do not rely on
radio altimeter inputs, but rather use radar altimeter data for
vertical situational awareness in low visibility conditions (i.e., snow
and dust blown up by rotor down wash) and as an input into several
procedures and automated system. This means that a 5G C-Band
interference event in most helicopters does not result in an erroneous
HTAWS alert.
    The FAA is concerned that 5G C-Band interference events will occur
more frequently as telecommunication companies continue to deploy 5G C-

Band services throughout the country and the safety benefit from the
use of radio altimeters in helicopters will be lost. On January 11,
2023, the FAA published an NPRM that would supersede AD 2021-23-12 for
transport and commuter category airplanes equipped with a radio
altimeter (88 FR 1520) (``transport NPRM''). The transport NPRM
proposed, in part, to require that after February 1, 2024, operations
under part 121 must be conducted with a radio altimeter tolerant
airplane. This proposed requirement was prompted by the FAA's
determination that erroneous system warnings due to a malfunctioning
radio altimeter will lead to flightcrew desensitization to system
warnings. The FAA has assessed the cumulative effects of increasing
numbers of erroneous warnings for rotorcraft, such as the display of
erroneous vertical position input to the pilot, and determined that it
has not yet risen to the level of an unsafe condition. For this reason,
the FAA is not proposing to mandate equipage of radio altimeters
meeting certain tolerance requirements for all helicopters, as proposed
in the transport NPRM for airplanes.
    Why New Corrective Action is Needed: The FAA expects an increase in
the number of 5G C-Band base stations around airports in the national
airspace system (NAS) and expects these stations to transmit in the
entire 5G C-Band frequency band (from 3.7 to 3.98 GHz). Since the FAA
issued AD 2021-23-13, which focused solely on a limited airspace
environment, 5G C-Band base stations have increasingly begun
transmission in other areas of the country. Whereas 5G C-Band
transmissions were initially limited to 3.7 to 3.8 GHz, these
transmissions have also begun to expand to 3.8 to 3.98 GHz, and the FAA
expects deployment at the higher end of the frequency range to expand
after July 1, 2023.\1\ These higher frequencies are nearer to the
spectrum allocation where radio altimeters operate (4.2 to 4.4 GHz),
which means that the potential for interference to radio altimeters
from in-band and spurious \2\ emissions may be more likely. In
addition, the FAA expects approximately 19 additional telecommunication
companies in addition to AT&T and Verizon will begin transmitting in
the C-Band at some point after June 2023.\3\ As the 21
telecommunication companies authorized to transmit 5G C-Band continue
to expand transmissions throughout the country, using NOTAMs to
identify affected areas and assessing proposed AMOCs will become
untenable. NOTAMs are temporary means of disseminating information
until the information can be publicized by other means. Given 5G C-Band
signals are not expected to be temporary and that 5G C-Band signals
will cover the contiguous U.S., NOTAMs are no longer the best means of
communicating the location of the 5G C-Band environment. In addition,
given the information gleaned over the past year, the FAA is now able
to identify the conditions under which radio altimeters can be relied
on to perform their intended function in the presence of a 5G C-Band
environment. Therefore, case-by-case AMOC approvals that allow
performing certain operations otherwise prohibited by an AD are no
longer the most efficient way for helicopter operators to show that
their radio altimeters perform their intended function in the 5G C-Band
environment.
---------------------------------------------------------------------------

    \1\ FCC licenses authorized 5G transmissions from 3.7 to 3.98
GHz.
    \2\ The tolerance to 5G spurious emissions is the level of
aggregate interference in the radio altimeter band below which the
installed radio altimeter system will meet its performance standards
and perform its intended function.
    \3\ The additional 19 telecommunications companies will have
access to the FCC-licensed spectrum after current users vacate use
of the frequencies.
---------------------------------------------------------------------------

    Determination of Rotorcraft Radio Altimeter Tolerance Requirements:
The FAA is proposing interference tolerance requirements for radio
altimeters that can be used across the affected fleet. Rotorcraft
meeting these proposed minimum performance levels would be allowed to
perform the prohibited operations in the contiguous U.S. airspace and
would no longer be required to include the RFM limitations specified in
AD 2021-23-12. After July 1, 2023, rotorcraft that do not meet the
proposed minimum performance levels would be subject to the prohibited
operations.
    The FAA determined the proposed interference tolerance requirements
by using the fuller understanding of specific radio altimeter
capabilities the FAA gained during the AMOC process for AD 2021-23-12
and AD 2021-23-13. This process revealed the radio altimeter
modifications that would not require a substantial system redesign,
allowing aircraft operators to readily replace radio altimeters or
install filters that allowed the aircraft to operate safely in a
mitigated 5G environment.
    The interference tolerance requirements are represented by a power
spectral density (PSD) curve. The PSD curve, as depicted in figure 1 to
paragraph (g)(1) of this proposed AD, represents the height over the
ground and received power from a 5G C-Band emitter, at or below which
the radio altimeter is expected to function reliably, measured in
decibel-milliwatts (dBm) per megahertz (MHz). For purposes of this
proposed AD, a ``radio altimeter tolerant rotorcraft'' is one for which
the radio altimeter, as installed, demonstrates tolerance to radio
altimeter interference at or above PSD curve threshold specified in
figure 1 to paragraph (g)(1) of this proposed AD. A radio altimeter
tolerant rotorcraft also demonstrates tolerance to an aggregate
spurious emission level of -42 dBm/MHz in the 4200-4400 MHz radio
altimeter band. For purposes of this proposed AD, a ``non-radio
altimeter tolerant rotorcraft'' is one for which the radio altimeter,
as installed, does not demonstrate those tolerances. Operators will
have the option to upgrade to a radio altimeter tolerant rotorcraft if
they wish to avoid the prohibitions in this proposed AD. Some operators
may need to install filters between the radio altimeter and antenna to
increase a radio altimeter's tolerance. For others, the addition of a
filter will not be sufficient to address interference susceptibility;
therefore, the radio altimeter will need to be replaced with an
upgraded radio altimeter. The FAA has determined that radio altimeter
tolerant rotorcraft are not expected to experience interference during
a critical phase of flight in the contiguous U.S. airspace.
    Areas of Operation: Over the past year, the FAA and the aviation
industry, using data voluntarily provided by AT&T and Verizon, have
identified maximum power levels for 5G C-Band transmissions that would
permit safe aircraft operations. This data includes 5G C-Band tower or
antenna locations, fundamental transmission power levels, and antenna
height. The FAA has found that rotorcraft meeting the proposed
standards as represented by the PSD curve can safely perform the
prohibited operations specified in this proposed AD. These operations
are safe for radio altimeter tolerant rotorcraft to perform within the
contiguous U.S. airspace as long as telecommunication companies
transmit at parameters under the current voluntary agreements with the
FAA and FCC.
    Compatibility with 5G C-Band Providers: The FAA has determined that
any U.S. 5G C-Band provider that maintains the mitigated actions will
not have an effect on the safety of rotorcraft with radio altimeters
that meet the interference tolerance requirements. The FAA will assess
the effects of any changes to transmission parameters in

the contiguous U.S. airspace to determine whether they would result in
a hazard to air navigation. If the transmission changes negatively
affect the safe operation of a radio altimeter tolerant rotorcraft, the
FAA will re-evaluate the risks and determine if further rulemaking is
warranted.
    Therefore, the FAA has determined that an unsafe condition exists
when performing certain operations in the presence of 5G C-Band
transmissions affecting the proper function of radio altimeters. For
that reason, operators would be required to revise their existing RFM
to prohibit these operations unless operating a radio altimeter
tolerant rotorcraft. This proposed requirement would take effect on
July 1, 2023.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.

Proposed AD Requirements in This NPRM

    For rotorcraft with radio altimeters that meet the proposed
interference tolerance requirements, this proposed AD would terminate
the operational limitations imposed by AD 2021-23-13 with no further
action.
    For rotorcraft with radio altimeters that do not meet the proposed
interference tolerance requirements, this proposed AD would retain the
requirement in AD 2021-23-13 to revise the existing RFM to incorporate
limitations prohibiting the following operations in the presence of 5G
C-Band wireless broadband interference as identified by NOTAM (NOTAMs
will be issued to state the specific airports where the radio altimeter
is unreliable due to the presence of 5G C-Band wireless broadband
interference) until June 30, 2023. On or before June 30, 2023, this
proposed AD would also require, for non-radio altimeter tolerant
rotorcraft, revising the existing RFM to incorporate limitations
prohibiting these same operations in the contiguous U.S. airspace.

Interim Action

    The FAA considers that this AD, if adopted as proposed, would be an
interim action. Once the Technical Standard Order (TSO) standard for
radio altimeters is established, which will follow the existing
international technical consensus on the establishment of the minimum
operational performance standards (MOPS), the FAA anticipates that the
MOPS will be incorporated into the TSO. The FAA also anticipates that
rotorcraft incorporating equipment approved under the new Radio
Altimeter TSO will be able to operate in the contiguous U.S. airspace
with no 5G C-Band-related RFM limitations. Once a new radio altimeter
TSO is developed, approved, and available, the FAA might consider
additional rulemaking.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 1,128 helicopters of U.S. registry. The FAA estimates the
following costs to comply with this proposed AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA has determined that this proposed AD would not have
federalism implications under Executive Order 13132. This proposed AD
would not have a substantial direct effect on the States, on the
relationship between the national Government and the States, or on the
distribution of power and responsibilities among the various levels of
government.
    For the reasons discussed above, I certify that the proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

33 CFR Part 165

[Docket Number USCG-2022-0072]
RIN 1625-AA00

Safety Zone; Potomac River, Between Charles County, MD and King
George County, VA

AGENCY: Coast Guard, DHS.

ACTION: Temporary final rule.

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

SUMMARY: The Coast Guard is establishing a temporary safety zone for
certain waters of the Potomac River. This action is necessary to
provide for the safety of persons, and the marine environment from the
potential safety hazards associated with construction operations at the
new Governor Harry W. Nice/Senator Thomas ``Mac'' Middleton Memorial
(US-301) Bridge, which will occur from 8 p.m. on February 4, 2022,
through 8 p.m. on February 11, 2022. This rule will prohibit persons
and vessels from being in the safety zone unless authorized by the
Captain of the Port, Maryland-National Capital Region or a designated
representative.

DATES: This rule is effective without actual notice from February 9,
2022, through 8 p.m. on February 11, 2022. For the purposes of
enforcement, actual notice will be issued from 8 p.m. on February 4,
2022, until February 9, 2022.

U.S.C. United States Code

II. Background Information and Regulatory History

    On February 2, 2022, Skanska-Corman-McLean, Joint Venture notified
the Coast Guard that the company will be setting structural steel
sections across the federal navigation channel at the new Governor
Harry W. Nice/Senator Thomas ``Mac'' Middleton Memorial (US-301)
Bridge. The bridge contractor stated the work required to set
structural steel across the channel, which was originally scheduled to
occur in November 2021, then rescheduled to December 2021, then
rescheduled to January 3-15, 2022, and again rescheduled to January 11-
22, 2022, was scheduled to occur from January 22, 2022 through February
4, 2022. However, an unexpected major winter weather event and the
resulting clean-up activity required on site following that event
halted operations and caused additional delays. The work is now
scheduled to occur from February 4, 2022, through February 11, 2022.
    The work described by the contractor requires the movement in and
anchoring at multiple points of a large crane barge within the federal
navigation channel. This crane can accommodate all of the steel to be
hoisted and placed, which will streamline the operation by avoiding
multiple reloads of steel and reducing the time in the channel by
multiple days. This operation will impede vessels requiring the use of
the channel. Note, the Coast Guard previously issued other temporary
safety zones at this location for placement of fender ring elements in
association with construction of the new bridge (Search dockets USCG-
2021-0127; USCG-2021-0650; USCG-2021-0745; USCG-2021-0906; USCG-2022-
0021; and USCG-2022-0031).
    The Coast Guard is issuing this temporary rule without prior notice
and opportunity to comment pursuant to authority under section 4(a) of
the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This
provision authorizes an agency to issue a rule without prior notice and
opportunity to comment when the agency for good cause finds that those
procedures are ``impracticable, unnecessary, or contrary to the public
interest.'' Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good
cause exists for not publishing a notice of proposed rulemaking (NPRM)
with respect to this rule because doing so would be impracticable and
contrary to the public interest. Construction operations involving
large crane heavy lifts at the new Governor Harry W. Nice/Senator
Thomas ``Mac'' Middleton Memorial (US-301) Bridge must occur within the
federal navigation channel. Immediate action is needed to respond to
the potential safety hazards associated with bridge construction.
Hazards from the construction operations include low-hanging or falling
ropes, cables, large piles and cement cast portions, dangerous
projectiles, and or other debris. We must establish this safety zone by
February 4, 2022 to guard against these hazards.
    Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause
exists for making this rule effective less than 30 days after
publication in the Federal Register. Delaying the effective date of
this rule would be impracticable and contrary to the public interest
because immediate action is needed to respond to the potential safety
hazards associated with construction operations at the new Governor
Harry W. Nice/Senator Thomas ``Mac'' Middleton Memorial (US-301) Bridge
to be conducted within the federal navigation channel.

III. Legal Authority and Need for Rule

    The Coast Guard is issuing this rule under authority in 46 U.S.C.
70034 (previously 33 U.S.C. 1231). The COTP has determined that
potential hazards associated with bridge construction starting February
4, 2022 will be a safety concern for anyone within the federal
navigation channel at the new Governor Harry W. Nice/Senator Thomas
``Mac'' Middleton Memorial (US-301) Bridge construction site. This rule
is needed to protect personnel, vessels, and the marine environment in
the navigable waters within the safety zone while the bridge is being
constructed.

IV. Discussion of the Rule

    This rule establishes a temporary safety zone from 8 p.m. on
February 4, 2022 through 8 p.m. on February 11, 2022. The safety zone
will cover all navigable waters of the Potomac River encompassed by a
line connecting the following points beginning at 38[deg]21'50.96'' N,
076[deg]59'22.04'' W, thence south to 38[deg]21'43.08'' N,
076[deg]59'20.55'' W, thence west to 38[deg]21'41.00'' N,
076[deg]59'34.90'' W, thence north to 38[deg]21'48.90'' N,
076[deg]59'36.80'' W, and east back to the beginning point located
between Charles County, MD and King George County, VA.
    The duration of the zone is intended to protect personnel and the
marine environment in these navigable waters while structural steel is
being set across the federal navigation channel at the new Governor
Harry W. Nice/Senator Thomas ``Mac'' Middleton Memorial (US-301)
Bridge.
    Except for marine equipment and vessels operated by Skanska-Corman-
McLean, Joint Venture, or its subcontractors, no vessel or person will
be permitted to enter the safety zone without obtaining permission from
the COTP Maryland-National Capital Region or a designated
representative.
    The COTP Maryland-National Capital Region will notify the public
that the safety zone will be enforced by all appropriate means to the
affected segments of the public, as practicable, in accordance with 33
CFR 165.7(a).

V. Regulatory Analyses

    We developed this rule after considering numerous statutes and
Executive orders related to rulemaking. Below we summarize our analyses
based on a number of these statutes and Executive orders, and we
discuss First Amendment rights of protestors.

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. This rule has not been designated a ``significant
regulatory action'' under Executive Order 12866. Accordingly, this rule
has not been reviewed by the Office of Management and Budget (OMB).
    This regulatory action determination is based on size and duration
of the safety zone. The temporary safety zone is approximately 450
yards in width and 270 yards in length. We anticipate that there will
be no vessels that are unable to conduct business. Excursion vessels
and commercial fishing vessels are not impacted by this rulemaking.
Excursion vessels do not operate in this area, and commercial fishing
vessels are not impacted because of their draft. Some towing vessels
may be impacted, but bridge project personnel have been conducting
outreach throughout the project in order to coordinate with those
vessels. Vessel traffic not required to use the navigation channel will
be able to safely transit around the safety zone. Such vessels may be
able to transit to the east or the west of the federal navigation
channel, as similar vertical clearance and water depth exist under the
next bridge span to the east and west. This safety zone will impact a
small designated area of the Potomac River for 7 days, but coincides
with the non-peak season for recreational boating.

B. Impact on Small Entities

    The Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, as
amended, requires Federal agencies to consider the potential impact of
regulations on small entities during rulemaking. The term ``small
entities'' comprises small businesses, not-for-profit organizations
that are independently owned and operated and are not dominant in their
fields, and governmental jurisdictions with populations of less than
50,000. The Coast Guard received no comments from the Small Business
Administration on this rulemaking. The Coast Guard certifies under 5
U.S.C. 605(b) that this rule will not have a significant economic
impact on a substantial number of small entities.
    While some owners or operators of vessels intending to transit the
temporary safety zone may be small entities, for the reasons stated in
section V.A above, this rule will not have a significant economic
impact on any vessel owner or operator.
    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small
entities in understanding this rule. If the rule would affect your
small business, organization, or governmental jurisdiction and you have
questions concerning its provisions or options for compliance, please
call or email the person listed in the FOR FURTHER INFORMATION CONTACT
section.
    Small businesses may send comments on the actions of Federal
employees who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247). The Coast Guard will not retaliate against small
entities that question or complain about this rule or any policy or
action of the Coast Guard.

C. Collection of Information

    This rule will not call for a new collection of information under
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

D. Federalism and Indian Tribal Governments

    A rule has implications for federalism under Executive Order 13132,
Federalism, if it has a substantial direct effect on the States, on the
relationship between the National Government and the States, or on the
distribution of power and responsibilities among the various levels of
government. We have analyzed this rule under that Order and have
determined that it is consistent with the fundamental federalism
principles and preemption requirements described in Executive Order
13132.
    Also, this rule does not have tribal implications under Executive
Order 13175, Consultation and Coordination with Indian Tribal
Governments, because it does not have a substantial direct effect on
one or more Indian tribes, on the relationship between the Federal
Government and Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.

E. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538)
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 (adjusted for
inflation) or more in any one year. Though this rule will not result in
such an expenditure, we do discuss the effects of this rule elsewhere
in this preamble.

F. Environment

    We have analyzed this rule under Department of Homeland Security
Directive 023-01, Rev. 1, associated implementing instructions, and
Environmental Planning COMDTINST 5090.1 (series), which guide the Coast
Guard in complying with the National Environmental Policy Act of 1969
(42 U.S.C. 4321-4370f), and have determined that this action is one of
a category of actions that do not individually or cumulatively have a
significant effect on the human environment. This rule involves a
temporary safety zone lasting 7 total days that will prohibit entry
within a portion of the Potomac River. It is categorically excluded
from further review under paragraph L60(a) of Appendix A, Table 1 of
DHS Instruction Manual 023-01-001-01, Rev. 1. A Record of Environmental
Consideration supporting this determination is available in the docket.
For instructions on locating the docket, see the ADDRESSES section of
this preamble.

G. Protest Activities

    The Coast Guard respects the First Amendment rights of protesters.
Protesters are asked to call or email the person listed in the FOR
FURTHER INFORMATION CONTACT section to coordinate protest activities so
that your message can be received without jeopardizing the safety or
security of people, places or vessels.
