33 CFR Part 165

[Docket Number USCG-2022-0995]
RIN 1625-AA00


Safety Zones in Reentry Sites; Panama City, Pensacola, and 
Tallahassee, Florida

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: This proposed rule would implement a special activities 
provision of the William M. (Mac) Thornberry National Defense 
Authorization Act for Fiscal Year 2021. The Coast Guard is proposing to 
establish three temporary safety zones for the safe splashdown and 
recovery of reentry vehicles launched by Space Exploration Technologies 
Corporation (SpaceX) in support of National Aeronautics and Space 
Administration (NASA) missions. The proposed temporary safety zones are 
located within the Coast Guard District Eight area of responsibility 
(AOR) offshore of Panama City, Pensacola, and Tallahassee, Florida. 
These proposed temporary safety zones are also located specifically 
within the Coast Guard Sector Mobile AOR. This proposed rule would 
prohibit U.S.-flagged vessels from entering any of the temporary safety 
zones unless authorized by the Commanding Officer of Coast Guard Sector 
Mobile or a designated representative. Foreign-flagged vessels would be 
encouraged to remain outside the safety zones. This action is necessary 
to protect vessels and waterway users from the potential hazards 
created by reentry vehicle splashdowns and recovery operations in the 
U.S. Exclusive Economic Zone (EEZ). It is also necessary to provide for 
the safe recovery of reentry vehicles, and any personnel involved in 
reentry services, after the splashdown. We invite your comments on this 
proposed rulemaking.

DATES: Comments and related material must be received by the Coast 
Guard on or before February 10, 2023.

ADDRESSES: You may submit comments identified by docket number USCG-
2022-0995 using the Federal Decision Making Portal at https://www.regulations.gov. See the ``Public Participation and Request for 
Comments'' portion of the SUPPLEMENTARY INFORMATION section for further 
instructions on submitting comments.

FOR FURTHER INFORMATION CONTACT: If you have questions about this 
proposed rulemaking, call or email Lieutenant Andrew Anderson Sector 
Mobile Waterways Division (dpw), U.S. Coast Guard; telephone: 251-441-

II. Background, Purpose, and Legal Basis

    On January 1, 2021, the William M. (Mac) Thornberry National 
Defense Authorization Act for Fiscal Year 2021 (Pub. L. 116-283) 
(Authorization Act) was enacted. Section 8343 (134 Stat. 4710) calls 
for the Coast Guard to conduct a two-year pilot program to establish 
and implement a process to establish safety zones to address special 
activities in the U.S. Exclusive Economic Zone (EEZ).\1\ These special 
activities include space activities \2\ carried out by United States 
(U.S.) citizens. Terms used to describe space activities, including 
launch, reentry site, and reentry vehicle, are defined in 51 U.S.C. 
50902, and in this document.
---------------------------------------------------------------------------

    \1\ The Coast Guard defines the U.S. exclusive economic zone in 
33 CFR 2.30(a). Territorial sea is defined in 33 CFR 2.22.
    \2\ Space Activities means space activities, including launch 
and reentry, as such terms are defined in section 50902 of Title 51, 
United States Code, carried out by United States citizens.
---------------------------------------------------------------------------

    The Coast Guard has long monitored space activities impacting the 
maritime domain and taken actions to ensure the safety of vessels and 
the public as needed during space launch \3\ operations. In conducting 
this activity, the Coast Guard engages with other government agencies, 
including the Federal Aviation Administration (FAA) and National 
Aeronautics and Space Administration (NASA), and private space 
operators, including Space Exploration Technologies Corporation 
(SpaceX). This engagement is necessary to ensure statutory and 
regulatory obligations are met to ensure the safety of launch 
operations and waterway users.
---------------------------------------------------------------------------

    \3\ The term launch is defined in 51 U.S.C. 50902.
---------------------------------------------------------------------------

    During this engagement, the Coast Guard was informed of space 
reentry vehicles and recovery operations in the U.S. EEZ. Section 50902 
of 51 U.S.C. defines ``reentry vehicle'' as a vehicle designed to 
return from Earth orbit or outer space to Earth, or a reusable launch 
vehicle designed to return from Earth orbit or outer space to Earth, 
substantially intact. SpaceX, a U.S. company, has identified three 
reentry sites \4\ within the U.S. EEZ of the Coast Guard District Eight 
area of responsibility (AOR) expected to be used for the splashdown \5\ 
and recovery of reentry vehicles. All of these sites are located in the 
Gulf of Mexico off the coast of Florida (FL).
---------------------------------------------------------------------------

    \4\ Reentry site means the location on Earth to which a reentry 
vehicle is intended to return (as defined in a license the FAA 
Administrator issues or transfers under this chapter).
    \5\ Splashdown refers to the landing of a reentry vehicle into a 
body of water.
---------------------------------------------------------------------------

    On May 4, 2022, we published a temporary final rule in the Federal 
Register (87 FR 26273) for two anticipated reentry vehicle recovery 
missions within the Coast Guard District Eight AOR offshore of Panama 
City, Pensacola, and Tallahassee, FL from April 17, 2022 through May 
15, 2022. Based on the date the Coast Guard was informed of the 
reentry, and the immediate need to establish the safety zone, the Coast 
Guard did not have sufficient time to publish a notice of proposed 
rulemaking (NPRM) for that rule. The Coast Guard additionally published 
recovery mission temporary final rules for the periods from August 22, 
2022 through September 30, 2022 (87 FR 51253) and October 12, 2022 
through November 10, 2022 (87 FR 61508).
    The purpose of this rulemaking is to ensure the protection of 
vessels and waterway users in the U.S. EEZ from the potential hazards 
created by reentry vehicle splashdowns and recovery operations, and the 
safe recovery of reentry vehicles and personnel involved in reentry 
services.\6\ The Coast Guard is proposing this rulemaking under 
authority of section 8343 of the Authorization Act.
---------------------------------------------------------------------------

    \6\ Reentry Services means (1) activities involved in the 
preparation of a reentry vehicle and payload, crew (including crew 
training), government astronaut, or space flight participant, if 
any, for reentry; and (2) the conduct of a reentry.
---------------------------------------------------------------------------

III. Discussion of Proposed Rule

    The Coast Guard is proposing to establish three temporary safety 
zones in the U.S. EEZ for the safe reentry vehicle splashdown and 
recovery of reentry vehicles launched by SpaceX in support of NASA 
missions through the remainder of the pilot period, which ends on 
February 4, 2024.
    The proposed temporary safety zones are located within the Coast 
Guard District Eight AOR offshore of Panama City, Pensacola, and 
Tallahassee, FL in the Gulf of Mexico. The proposed rule would prohibit 
U.S.-flagged vessels from entering any of the safety zones unless 
authorized by the Commanding Officer of Coast Guard Sector Mobile or a 
designated representative. Because the safety zones are within the U.S. 
EEZ, only U.S.-flagged vessels would be subject to enforcement. 
However, all foreign-flagged vessels would be encouraged to remain 
outside the safety zones.
    The three proposed temporary safety zones are located off the coast 
of FL in the Gulf of Mexico in the following areas: (1) Approximately 
30 NM southwest from Pensacola; (2) 26 NM southwest from Panama City; 
and 40 NM south of Tallahassee. All three safety zones have an 
approximate area of 100 square miles and are in the shape of a square.
    The coordinates for the safety zones are based on the furthest 
north, east, south, and west points of the reentry vehicles splashdown 
and are determined from data and modeling by SpaceX and NASA. The 
coordinates take into account the trajectories of the reentry vehicles 
coming out of orbit, the potential risk to the public, and the 
proximity to medical facilities that meet NASA requirements. The 
specific coordinates for the three temporary safety zones are presented 
in the regulatory text at the end of this document.
    To the extent feasible, the Sector Commander or a designated 
representative would inform the public of the activation of the three 
temporary safety zones by Notice of Enforcement (NOE) published in the 
Federal Register at least two days before the reentry vehicle 
splashdown. The NOE would identify the approximate date(s) during which 
a reentry vehicle splashdown and recovery operations would occur.
    To the extent possible, twenty-four hours before a reentry vehicle 
splashdown and recovery operations, the Sector Commander or designated 
representative would inform the public that only one of the three 
safety zones would remain activated (subject to enforcement) until 
announced by Broadcast Notice to Mariners (BNM) on VHF-FM channel 16, 
and/or Marine Safety Information Bulletin (MSIB) (as appropriate) that 
the safety zone is no longer subject to enforcement. The specific 
temporary safety zone to be enforced would be based on varying mission 
and environmental factors, including atmospheric conditions, sea state, 
weather, and orbital calculations.
    The MSIB would include the geographic coordinates of the activated

[[Page 1530]]

safety zone, a map identifying the location of the activated safety 
zone, and information related to potential hazards associated with a 
reentry vehicle splashdown and recovery operations associated with 
space activities, including marine environmental and public health 
hazards, such the release of hydrazine and other potential oil or 
hazardous substances.
    When the safety zone is activated, the Sector Commander or a 
designated representative would be able to restrict U.S.-flagged vessel 
movement including but not limited to transiting, anchoring, or mooring 
within the safety zone to protect vessels from hazards associated with 
space activities. The activated safety zone would ensure the protection 
of vessels and waterway users from the potential hazards created by 
reentry vehicle splashdowns and recovery operations. This includes 
protection during the recovery of a reentry vehicle, and the protection 
of personnel involved in reentry services and space support vessels.\7\
---------------------------------------------------------------------------

    \7\ Space Support Vessel means any vessel engaged in the support 
of space activities. These vessels are typically approximately 170 
feet in length, have a forward wheelhouse, and are equipped with a 
helicopter pad and lifting crane.
---------------------------------------------------------------------------

    After a reentry vehicle splashdown, the Sector Commander or a 
designated representative would grant general permission to come no 
closer than 3 NM within the activated safety zone from any reentry 
vehicle or space support vessel engaged in the recovery operations. The 
recovery operations are expected to last approximately one hour. That 
should allow for sufficient time to let any potential toxic materials 
clear the reentry vehicle, recovery of the reentry vehicle by the space 
support vessel, and address any potential medical evacuations for any 
personnel involved in reentry services that were onboard the reentry 
vehicle.
    Once a reentry vehicle and any personnel involved in reentry 
services are removed from the water and secured onboard a space support 
vessel, the Sector Commander or designated representative would issue a 
BNM on VHF-FM channel 16 announcing the activated safety zone is no 
longer subject to enforcement. A photograph of a reentry vehicle and 
space support vessel expected to use the reentry sites are available in 
the docket.

IV. Regulatory Analyses

    We developed this proposed 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 NPRM has not been designated a ``significant 
regulatory action,'' under Executive Order 12866. Accordingly, the NPRM 
has not been reviewed by the Office of Management and Budget (OMB).
    This regulatory action determination is based on the size, 
location, duration, and scope of the temporary safety zones. The 
temporary safety zones are limited in size and location to only those 
areas where reentry vehicles splashdown and recovery operations occur. 
The safety zones are limited in scope, as vessel traffic would be able 
to safely transit around the activated safety zone which will only 
impact a small part of the U.S. EEZ within the Gulf of Mexico. The 
proposed rule involves the establishment of three temporary safety 
zones which would be activated two days before a reentry vehicle 
splashdown and recovery operations. Twenty-four hours before a reentry 
vehicle splashdown, one of the three temporary safety zones would 
remain active. After a reentry vehicle splashdown, general permission 
would be granted to come no closer than 3 NM within the activated 
safety zone. There is a danger associated with fumes from the reentry 
vehicle after it has splashed down. Once a reentry vehicle and any 
personnel involved in reentry services are removed from the water and 
secured onboard a space support vessel, the activated safety zone would 
no longer be subject to enforcement. The activated safety zone would 
ensure the protection of vessels and waterway users from the potential 
hazards created by a reentry vehicle splashdown and recovery operations 
and the recovery of a reentry vehicle, personnel involved in reentry 
services, and space support vessel.

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 certifies under 5 U.S.C. 605(b) that this 
proposed rule would not have a significant economic impact on a 
substantial number of small entities.
    The safety zones are only expected to last a few hours from reentry 
vehicle splashdown to recovery. Vessels will be able to transit around 
the activated safety zone location during these recoveries. We do not 
anticipate any significant economic impact resulting from activation of 
the safety zones.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity, and that this proposed rule 
would have a significant economic impact on it, please submit a comment 
(see ADDRESSES) explaining why you think it qualifies and how and to 
what degree this rule would economically affect it.
    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 proposed rule. If the proposed 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. The Coast Guard will not 
retaliate against small entities that question or complain about this 
proposed rule or any policy or action of the Coast Guard.

C. Collection of Information

    This proposed rule would 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 proposed 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 proposed rule does not have tribal implications under 
Executive Order 13175 (Consultation and Coordination with Indian Tribal 
Governments) because it would 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

[[Page 1531]]

Federal Government and Indian tribes. If you believe this proposed rule 
has implications for federalism or Indian tribes, please call or email 
the person listed in the FOR FURTHER INFORMATION CONTACT section.

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 proposed rule would not 
result in such an expenditure, we do discuss the potential effects of 
this proposed rule elsewhere in this preamble.

F. Environment

    We have analyzed this proposed 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 made 
a preliminary determination 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 proposed rule involves the 
establishment of three temporary safety zones which would be activated 
two days before a reentry vehicle splashdown and recovery operations. 
Twenty-four hours before a reentry vehicle splashdown, one of the three 
temporary safety zones would remain active. After a reentry vehicle 
splashdown, general permission would be granted to come no closer than 
3 NM within the activated safety zone. Once a reentry vehicle and any 
personnel involved in reentry services are removed from the water and 
secured onboard a space support vessel, the activated safety zone would 
no longer be subject to enforcement. Normally such actions are 
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 
preliminary 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. We seek any 
comments or information that may lead to the discovery of a significant 
environmental impact from this proposed rule.

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.
