Background Information and Regulatory History</HD> The Coast Guard is issuing this temporary rule under the authority in 5 U.S.C. 553(b)(B). This statutory 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.” The Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because there is an immediate need to mitigate the risk of vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway because of their proximity to the low flying aircrafts. Prompt action is needed to respond to the potential safety hazards associated with vessels transiting in the proximity of the runway of Cyril E. King Airport in St. Thomas, USVI. It is impracticable to publish an NPRM because we must establish this safety zone by August 5, 2025 or as soon as practicable after this date. Also, 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 <E T="04">Federal Register</E> . Delaying the effective date of this rule would be impracticable because prompt action is needed to respond to the potential safety hazards associated with vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway and their proximity to the low flying aircrafts. <HD SOURCE="HD1">III. Legal Authority and Need for Rule</HD> The Coast Guard is issuing this rule under authority in 46 U.S.C. 70034. The Captain of the Port Sector San Juan (COTP) has determined potential hazards associated with vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway and their proximity to the low flying aircrafts. There is a safety concern for any vessel transiting within approximately 400 yards from shore directly west of the airport's runway. This rule is needed to protect personnel, vessels, and the marine environment in the navigable waters within the safety zone while a permanent solution is being assessed by the FAA, St. Thomas airport, and Coast Guard. <HD SOURCE="HD1">IV. Discussion of the Rule</HD> This rule establishes a safety zone from August 5, 2025, through September 30, 2025. The safety zone will cover all navigable waters within 400 yards from shore directly west of the airport's runway within the two private port authority managed yellow buoys located at 18°20.288′ N—64°59.343′ W and 18°20.116′ N—64°59.343′ W. The duration of the zone is intended to protect personnel, vessels, and the marine environment in these navigable waters while the risks are assessed and solutions are proposed. No vessel or person will be permitted to enter the safety zone without obtaining permission from the COTP San Juan or a designated representative. <HD SOURCE="HD1">V. Regulatory Analyses</HD> 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. <HD SOURCE="HD2">A. Regulatory Planning and Review</HD> Executive Orders 12866 (Regulatory Planning and Review) and 13563 (Improving Regulation and Regulatory Review) 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. The Office of Management and Budget (OMB) has not designated this rule a “significant regulatory action,” under section 3(f) of Executive Order 12866. Accordingly, OMB has not reviewed it. This regulatory action determination is based on: (1) the safety of personnel, vessels, and the marine environment from potential hazards created by vessels transiting in the proximity of the approach to the Cyril E. King airport's runway; (2) although vessels may not enter, transit through, anchor in, or remain within the safety zone without authorization from the COTP or a designated representative, they may operate in the surrounding area outside the safety zone during the enforcement period. <HD SOURCE="HD2">B. Impact on Small Entities</HD> 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 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 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 will 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 <E T="02">FOR FURTHER INFORMATION CONTACT</E> 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. <HD SOURCE="HD2">C. Collection of Information</HD> This rule will not call for a new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). <HD SOURCE="HD2">D. Federalism and Indian Tribal Governments</HD> 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. <HD SOURCE="HD2">E. Unfunded Mandates Reform Act</HD> The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) requires Federal ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 14k characters.
