2026-13137, Marine Casualty Reporting on the Outer Continental Shelf
Starting July 30, 2026, companies working on the Outer Continental Shelf must report marine accidents based on who’s involved, not just where they happen. The rule raises the damage cost that triggers a report from $25,000 to $75,000, saving businesses money and making rules clearer and fairer. This change cuts industry costs by over $10,000 in 10 years and aligns U.S. rules with international standards for offshore activities.

2026-16118, Safety Zone; Chevron GENESIS SPAR Outer Continental Shelf Facility, Green Canyon Block 205A, Gulf of America
The Coast Guard is proposing to disestablish a safety zone around the GENESIS SPAR facility, previously located in Green Canyon Block 205A on the Outer Continental Shelf (OCS) in the Gulf of America. The GENESIS SPAR facility was decommissioned and fully removed by the Chevron Corporation in June of 2024. This proposed rulemaking would disestablish the permanent safety zone and remove the regulatory text of 33 CFR 147.825. We invite your comments on this proposed rulemaking.

The Coast Guard proposes to modify the operating schedule that governs the Union Pacific Railroad (UPRR) drawbridge that crosses the Old Brazos River, mile 5.3, near Brazoria, TX. UPRR has proposed to remotely operate the drawbridge from their train yard located in Brazos, TX. The Coast Guard temporarily changed the regulation to test this system. During the test the drawbridge continued to operate safely and provided boats and mariners with a reasonable ability to use this waterway. We invite your comments on this proposed rulemaking.
