Coast Guard Proposes Permanent Security Zone for Los Angeles Harbor Base Amidst Evolving Threats

The U.S. Coast Guard is moving to implement a permanent security zone in the navigable waters of the Los Angeles Harbor's main channel, specifically around its base on Terminal Island. This proposed rule, published as a Notice of Proposed Rulemaking, seeks to safeguard military personnel, vessels, and critical government property following a history of incidents that have necessitated immediate response actions.

The Need for Enhanced Security

The Captain of the Port (COTP) Los Angeles-Long Beach has identified a clear and present need for a dedicated, permanent security measure. In the past, various activities occurring directly adjacent to or beneath Coast Guard assets have posed security and safety risks. These past occurrences have required the Coast Guard to initiate rapid responses to protect the personnel and assets stationed at its Los Angeles-Long Beach base. The proposed 40-yard security zone is a proactive step to prevent future security breaches and ensure continuous protection.

Details of the Proposed Security Zone

Under this proposal, a security zone would be established extending 40 yards into the navigable waters from the entire perimeter of the Coast Guard Base on Terminal Island. Within this designated area, all persons and vessels would be prohibited from entering, transiting, or anchoring without explicit authorization from the Captain of the Port Los Angeles-Long Beach or their designated representative. The rule specifies that permission can be requested by contacting the United States Coast Guard Sector Los Angeles-Long Beach Command Center. Those within the zone would be required to comply with all lawful orders from the COTP or their representatives. The Coast Guard anticipates this rule would take effect on October 1, 2026.

Legal Authority and Regulatory Analysis

The Coast Guard bases this proposed rulemaking on its authority under 46 U.S.C. 70051 and 70124. These statutes grant the Coast Guard broad powers to establish security zones and take other actions necessary to protect ports, vessels, and facilities from security threats. The agency has conducted several regulatory analyses to assess the potential impact of this rule.

Significantly, the Coast Guard certifies that this proposal would not have a significant economic impact on a substantial number of small entities. It argues that vessel traffic can still safely transit the main channel, as the regulated area is small. Furthermore, the Coast Guard plans to issue Local Notices to Mariners and Marine Safety Information Bulletins to inform the maritime community. It also states the rule will not necessitate new information collection under the Paperwork Reduction Act. The proposal is consistent with federalism principles, has no tribal implications, and does not impose unfunded mandates on state, local, or tribal governments. From an environmental perspective, the Coast Guard determined the action is categorically excluded from further review under the National Environmental Policy Act.

Public Participation

As part of the rulemaking process, the Coast Guard is inviting public comments on this proposed action. Interested parties have until September 11, 2026, to submit their feedback and related materials. Comments can be submitted electronically through the federal eRulemaking portal. This public comment period is crucial for ensuring that all perspectives are considered before the final rule is promulgated.
