Sec.  Section
U.S.C. United States Code

II. Background, Purpose, and Legal Basis

    In February 2024, Seaport Manatee requested the establishment of a 
Coast Guard security zone in vicinity of Seaport Manatee facilities and 
ship berths to bolster protection of the port. The security zone would 
enhance safety and protect vessels, facilities, and waterfront 
infrastructure from potential threats. The security zone would prevent 
unauthorized access, sabotage, and damage to vessels, infrastructure, 
and human life. Throughout 2024, the Tampa Bay Harbor Safety and 
Security Committee (TBHSSC), as well as the Area Maritime Security 
Committee (AMSC), have discussed and are in concurrence that an 
additional security zone in Port Manatee would enhance Port Safety and 
Security, aligning with goals of the Area Maritime Safety Plan (AMSP). 
The purpose of this rulemaking is to ensure the security of protected 
vessels, facilities and waterfront infrastructure from potential 
threats in the vicinity of Seaport Manatee. The Coast Guard may issue 
security zone regulations under authority in 46 U.S.C. 70051 and 70124.

III. Discussion of Proposed Rule

    This rule establishes a permanent security zone in the vicinity of 
Seaport Manatee facilities and ship berths to bolster protection of the 
port. Entry into this security zone is prohibited unless specifically 
authorized by COTP or their designated representative. A designated 
representative is a commissioned, warrant, or petty officer of the U.S. 
Coast Guard assigned to units under the operational control of the U.S. 
Coast Guard Sector St. Petersburg. The regulatory text we are proposing 
appears at the end of this document.

IV. Regulatory Analyses

    We developed this proposed rule after considering numerous statutes 
and Executive orders related to rulemaking. Below we summarize our 
analysis based on a number of these statutes and Executive orders.

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 13563 emphasizes the importance of 
quantifying both costs and benefits, of reducing costs, of harmonizing 
rules, and of promoting flexibility. This NPRM has not been designated 
a ``significant regulatory action'' under section 3(f) of 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 and 
location of the security zone. Vessel traffic would be able to safely 
transit around this security zone which would impact a small, 
designated area around Seaport Manatee Piers and facility.

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.
    While some owners or operators of vessels intending to transit the 
security zone may be small entities, for the reasons stated in section 
IV.A above, this proposed rule would not have a significant economic 
impact on any vessel owner or operator.
    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

[[Page 36413]]

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 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 a 
permanent security zone that will extend 50 yards from the shore, 
seawall, and piers around the ship berths at Seaport Manatee. 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.
