<HD SOURCE="HED">SUMMARY:</HD>
The Coast Guard is proposing to amend a special local regulation for certain waters of the Patapsco River, in Baltimore, MD by adding a new period during which this regulation would be subject to enforcement. This action is necessary to provide for the safety of life on these navigable waters during the 3rd and 4th weeks of June, during Fleet Week events. This rule would prohibit persons and vessels from entering the regulated area during this enforcement period unless authorized by the Captain of the Port Maryland-National Capital Region or the Coast Guard Patrol Commander.

<HD SOURCE="HD1">II. Background, Purpose, and Legal Basis</HD>
“Historic Ships in Baltimore, Inc.” is the sponsor of an event titled “Air Show Baltimore,” which is held every two years in the Patapsco River, including the Inner Harbor, in Baltimore, MD. To address potential hazards arising from the event, the Coast Guard has promulgated a Special Local Regulation (SLR) which is codified in 33 CFR 100.501. Normally, Air Show Baltimore is held on one four-day (Thursday through Sunday) weekend in September or October. This year, however, “Historic Ships in Baltimore, Inc.,” together with Fleet Week 2026, and Sail250, Inc., all of Baltimore, MD, have notified the Coast Guard that they will be conducting the Air Show Baltimore in conjunction with a Fleet Week celebration from 12 noon to 4 p.m. daily from June 24, 2026, to July 01, 2026.
The biennial air show consists of various types of military aircraft performing low-flying, high-speed precision maneuvers and aerial stunts. The U.S. Navy's Blue Angels flight demonstration squadron aircraft will practice between 12 noon and 4 p.m. on June 24-25, 2026, and all air show performers will conduct a full practice show rehearsal will from 12 noon to 4 p.m. on June 25, 2026. The proposed new enforcement period would begin two hours before and end two hours after the hours during which air shows would be scheduled to occur.
<HD SOURCE="HD1">III. Discussion of Proposed Rule</HD>
The existing SLR is subject to all the requirements which pertain generally to SLRs in § 100.501, as well as to specific requirements set out in paragraph (h)(2) of that section. The regulated area, which would not change, and periods during which the SLR are currently subject to enforcement are set out in the first row of Table 2 to paragraph (i)(2) of § 100.501. The existing SLR is currently only subject to enforcement on one of three four-day (Thursday through Sunday) weekends in September or October on alternating years. The sole purpose of the proposed rule would is to create a new enforcement period, from 10 a.m. to 6 p.m. from June 24 to July 1.
Except for Air Show Baltimore participants and vessels already at berth, a vessel or person would be required to get permission from the COTP or PATCOM before entering the regulated area during the proposed enforcement period. Vessel operators would request permission to enter and transit through the regulated area by contacting the COTP or PATCOM on VHF-FM channel 16. A person or vessel not registered with the event sponsor as a participant or assigned as official patrols would be considered a non-participant. Official Patrols are any vessel assigned or approved by the Commander, Coast Guard Sector Maryland-National Capital Region with a commissioned warrant, or petty officer on board and displaying a Coast Guard ensign.
If permission is granted by the COTP or PATCOM, a non-participant would be allowed to enter the regulated area or pass directly through the regulated area as instructed. Vessels would be required to operate at a safe speed that minimizes wake while within the regulated area, in a manner that would not endanger event participants or any other craft. Official patrol vessels would direct non-participants while within the regulated area. The air show aerobatics areas located within the regulated areas is restricted to Air Show Baltimore participants.

<HD SOURCE="HD1">IV. Regulatory Analyses</HD>
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.
<HD SOURCE="HD2">A. 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 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 safety 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. The Coast Guard will work closely with small business entities to organize transit and minimize impacts to business.
If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this rule would have a significant economic impact on it, please submit a comment (see
<E T="02">ADDRESSES</E>
) 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 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
<E T="02">FOR FURTHER INFORMATION CONTACT</E>
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.
<HD SOURCE="HD2">C. Collection of Information</HD>
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).
<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 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
<E T="02">FOR FURTHER INFORMATION CONTACT</E>
section.
<HD SOURCE="HD2">E. Unfunded Mandates Reform Act</HD>
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 effects of this rule elsewhere in this preamble.
<HD SOURCE="HD2">F. Environment</HD>
We have analyzed this proposed rule under Department of Homeland Security Directive 023-01, Rev. 1
