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: Final rule.

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

SUMMARY: The Coast Guard is establishing 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 
temporary safety zones are located within the Coast Guard Sector Mobile 
area of responsibility (AOR) offshore of Panama City, Pensacola, and 
Tallahassee, Florida. This rule prohibits 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 are 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 ensure the safe recovery 
of reentry vehicles, and any personnel involved in reentry services, 
after the splashdown. We received no public comments.

DATES: This rule is effective from March 3, 2023 through February 4, 
2024.

II. Background Information and Regulatory History

    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 operations.\3\ 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).
    On January 11, 2023, the Coast Guard published a notice of proposed 
rulemaking (NPRM) in the Federal Register titled, ``Safety Zones in 
Reentry Sites; Panama City, Pensacola, and Tallahassee, Florida.'' (88 
FR 1528) In the NPRM, we stated the purpose of the rulemaking was to 
create three temporary safety zones off the coast of FL that would 
ensure the protection of vessels and waterway users in the U.S. 
Exclusive Economic Zone (EEZ) \6\ from the potential hazards created by 
reentry vehicle splashdowns \7\ and recovery operations, and the safe 
recovery of reentry vehicles and personnel involved in reentry 
services.\8\ The NPRM invited comments on the proposed rule. During the 
comment period that ended February 10, 20223, we received one comment.
---------------------------------------------------------------------------

    \6\ 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.
    \7\ Splashdown refers to the landing of a reentry vehicle into a 
body of water.
    \8\ 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.
---------------------------------------------------------------------------

    With this temporary final rule, the Coast Guard is ensuring the 
three temporary safety zones created by this TFR are in place for the 
safe reentry vehicle splashdown and recovery of reentry vehicles 
missions launched by SpaceX in support of NASA missions, and privately 
chartered missions during the remaining period of the pilot program, 
which ends on February 4, 2024.

III. Legal Authority and Need for Rule

    The Coast Guard is issuing this rule under section 8343 of the 
Authorization Act. The Sector Commander Sector Mobile has determined 
there are potential hazards in the U.S. EEZ created by reentry vehicle 
splashdowns and recovery operations, and the safe recovery of reentry 
vehicles and personnel involved in reentry services. The purpose of 
this rule is to ensure safety of vessels, reentry vehicles, personnel 
involved in reentry services and the navigable waters in the safety 
zone, whenever a splashdown occurs.
    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 because delaying the effective date 
of the rule would be impracticable and contrary to the public interest. 
This rule is needed to ensure there are safety zones in place for 
upcoming recovery operations. Delaying the enforcement of this rule to 
allow a 30-day effective period would inhibit the Coast Guard's ability 
to fulfill its mission 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.

IV. Discussion of Comments and the Rule

    As noted above, we received one comment on the NPRM that was 
published on January 10, 2023. The commenter stated that a notice to 
the public of space recovery operations in the Federal Register alone, 
in their opinion, was insufficient. We concur with this opinion and 
that is why the Coast Guard has three different means of

[[Page 13318]]

disseminating this information as prescribed in this rule.
    The temporary safety zones are located within the Coast Guard 
Sector Mobile AOR offshore of Panama City, Pensacola, and Tallahassee, 
FL in the Gulf of Mexico. The temporary final rule prohibits U.S.-
flagged vessels from entering any of the safety zones unless authorized 
by the Sector Commander 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 are encouraged to remain outside the safety 
zones.
    The three 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 splashdown for the reentry 
vehicles 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 will 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 will 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 
Safety Marine Information Broadcast (SMIB) (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 SMIB will include the geographic coordinates of the activated 
safety zone, pertinent dates and times of enforcement, and information 
related to potential hazards with a reentry vehicle splashdown and 
recovery operations associated with space activities, including marine 
environmental and public health hazards from hydrazine and other 
potential oil or hazardous substances.
    When the safety zone is activated, the Sector Commander or a 
designated representative will 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 will 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.\9\
---------------------------------------------------------------------------

    \9\ 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.

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 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

[[Page 13319]]

with populations of less than 50,000. The Coast Guard received 0 
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.
    The safety zone activation and thus restriction to the public is 
expected to be approximately two hours per capsule recovery, and we 
anticipate one splash down during the effective period of this rule. 
Vessels would be able to transit around the activated safety zone 
location during this recovery. We do not anticipate any significant 
economic impact resulting from activation of the safety zones.
    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 the 
establishing 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 activated. If one of the safety 
zones remains activated, the safety zone will be enforced for 
approximately four hours prior to a reentry vehicle splashdown and 
remain activated until announced by BNM on VHF-FM channel 16, and/or 
SMIB (as appropriate) that the safety zone is no longer subject to 
enforcement. 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. 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.

permission to come no closer than three nautical miles of any reentry 
vehicle or space support vessel engaged in the recovery operations, 
within the activated safety zone described in paragraph (a) of this 
section.
    (4) Once a reentry vehicle, and any personnel involved in reentry 
service, are removed from the water and secured onboard a space support 
vessel, the Captain of the Port Sector Mobile or designated 
representative will issue a Broadcast Notice to Mariners on VHF-FM 
channel 16 announcing the activated safety zone is no longer subject to 
enforcement.
