**II. Background, Purpose and Legal Basis**
Little River Bridge across the AICW (Upper Little River), mile 347.3, at North Myrtle Beach, SC, is a swing bridge with a 7-foot vertical clearance at mean high water in the closed position. The normal operating schedule for the bridge is set forth in 33 CFR 117.5.
On May 13, 2025, the Coast Guard published a temporary deviation entitled “Drawbridge Operation Regulation; Atlantic Intracoastal Waterway, North Myrtle Beach, SC” in the *Federal Register* (90 FR 20235). The temporary deviation, effective from 12:01 a.m. on May 5, 2025, through 11:59 p.m. on October 31, 2025, allows Little River Bridge to operate with restricted, scheduled openings at peak traffic times during weekdays and operate on demand at all other times. The temporary deviation was authorized to test the impact of restricted openings on vessels and roadway traffic. The comment period ended June 27, 2025, with zero comments received.
We are reopening the comment period on the same docket number and docket name where we posted the temporary deviation. Both the NPRM and the temporary deviation documents can be found at *https://www.regulations.gov.*
**III. Discussion of Proposed Rule**
The current operating schedule allows the Little River Bridge to open on demand for marine traffic. Under this proposed rule, the swing bridge will open twice an hour, at the top and bottom of the hour, Monday through Friday during pre-designated times. The on demand openings are causing excessive vehicle congestion during designated rush hour periods. The Coast Guard is proposing to limit swing bridge openings during high vehicle traffic times to assist with vehicle congestion while requesting state and local agencies consider alternate mitigation measures to improve traffic flow and roadway congestion. The swing bridge will open on demand at all other times. Vessels that can pass beneath the bridge without an opening may do so at any time. Public vessels of the United States, tugs with tows and vessels in distress may pass anytime.
**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 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. This proposed rule 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).
**B. Impact on Small Entities**
The Regulatory Flexibility Act of 1980 (RFA), 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.
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 *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 contact 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 call for no 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 contact 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 will not result in such an expenditure, we do discuss the effects of this proposed rule elsewhere in this preamble.
**F. Environment**
We have analyzed this rule under Department of Homeland Security Management Directive 023-01, Rev.1, associated implementing instructions, and Environmental Planning Policy COMDTINST 5090.1 (series), which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f). The Coast Guard has 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 proposed rule promulgates the operating regulations or procedures for drawbridges. Normally such actions are categorically excluded from further review, under paragraph L49, of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 1.
Neither a Record of Environmental Consideration nor a Memorandum for the Record are required for this rule. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule.
