Coast Guard Locks Down Dangerous Ships in Texas Waters

Published Date: 12/23/2025

Proposed Rule

Summary

The Coast Guard wants to set up special security zones around ships carrying dangerous cargo in Corpus Christi’s ship channels to keep everyone safe from accidents or attacks. This new rule affects ship operators and the public, with security zones activated when needed. You’ve got until January 22, 2026, to share your thoughts—no extra fees, just safer waters ahead!

Analyzed Economic Effects

4 provisions identified: 1 benefits, 1 costs, 2 mixed.

Permanent Security Zone for Dangerous Cargo

The Coast Guard proposes a permanent security zone that can be activated by the Captain of the Port (COTP) around vessels carrying Certain Dangerous Cargo (CDC) in the Corpus Christi and La Quinta Ship Channels. The zone would be used case-by-case to protect vessels, the public, and nearby areas from sabotage or similar threats; the agency noted over 450 CDC vessel movements in the last two years and projects that number to nearly double in the next 15 years.

Clear Distance and Permission Rules

When activated, security zones will cover a 500-yard radius around CDC vessels in the Corpus Christi or La Quinta Shipping Channels; vessels must not come within 100 yards of a CDC vessel unless authorized by the COTP. Vessels may transit through the zone only at the minimum speed necessary to maintain course and must request permission on VHF-FM channel 16 or by telephone at 361-939-0450.

Activations Short and Notified Publicly

The Coast Guard says CDC transits typically last up to six hours and that the COTP will notify the public of specific enforcement dates and times and vessel names by Broadcast Notices to Mariners (BNMs) or Marine Safety Information Bulletins (MSIBs). The COTP may also enlist federal, state, county, or municipal law enforcement to assist in enforcement.

Coast Guard Certifies Minimal Small-Entity Economic Impact

Under the Regulatory Flexibility Act, the Coast Guard certifies this proposed rule would not have a significant economic impact on a substantial number of small entities, reasoning the restriction is to a small area (500-yard radius) for periods of six hours or less and most vessels can move around the zone or request permission to enter.
