§70001 Vessel Traffic Services
Title 46 › Subtitle Subtitle VII— Security and Drug Enforcement › Chapter 700— PORTS AND WATERWAYS SAFETY › Subchapter I— VESSEL OPERATIONS › § 70001
Summary
The Secretary can set up and run vessel traffic services in U.S. ports, navigable waters, or areas covered by international agreements. These services help control ship movement and protect navigation and the marine environment by using reports, surveillance, routing, communications, and similar measures. The Secretary must make vessels in those areas follow the service and can require certain navigation or communications equipment, but cannot force fishing vessels under 300 gross tons or recreational vessels 65 feet or less to carry that gear just under this law. In dangerous conditions the Secretary can limit when and how vessels enter, move, or leave, set routing and size/speed/draft limits, and allow only vessels with needed capabilities. Vessels headed to U.S. ports may have to send prearrival messages in time for planning. Devices that interfere with navigation or communication can be banned, except for FCC-certified maritime devices using 157.1875–157.4375 MHz and 161.7875–162.0375 MHz. Within one year the Secretary must publish a national VTS policy and keep it updated. That policy must standardize roles, organization, authorities, monitoring thresholds, procedures, training, certification, standard language, and data handling. Local differences are allowed; captains of the port can submit regional policies for approval and the Secretary must review them within 180 days and keep a central record of approved variances. The Secretary can make cooperative agreements with public, private, or international partners, but private groups cannot perform inherently governmental functions. Information released to the public must be de-identified. The Secretary must set a standard way to evaluate VTS centers and collect data on traffic volumes, hazardous cargo, near-miss events, marine casualties, operator actions, and other measures, and must report to Congress within 1 year and every two years. A continuous risk assessment program must be developed using traffic, cargo, incident, location, weather, and other data, coordinated with NOAA, stored in a standard format, and made public under section 552 of title 5 after de-identification. A nationwide training and competency program must be made for VTS staff, including realistic scenarios, navigation rules, communications, display-system use, standard marine phrases, minimum training hours, testing, and repeat testing at intervals not more frequent than once every 5 years. The Secretary will research better radio monitoring and whether professional mariners should serve on watchfloors and will place them where feasible. The National Navigation Safety Advisory Committee will study AIS for non-self-propelled vessels carrying hazardous liquids and the Secretary may set rules. The Secretary must periodically review VTS areas using performance and risk data, seek stakeholder input, and can change or add VTS areas. Pilots and non-Federal entities helping the Coast Guard at VTS centers are protected from liability for their assistance unless they act with gross negligence or willful misconduct. Certain Notice of Arrival rules do not apply to documented vessels unless they come from a foreign port. Nothing here reduces other authorities the Secretary already has. Definitions (one line each): “Hazardous liquid cargo” – meaning given in title 49 regulations; “Marine casualty” – meaning given in its regulations; “Vessel traffic service area” – an area listed in the regulations at 33 C.F.R. part 161 subpart C; “Vessel traffic service center” – the center that runs a service area; “Near-miss incident” – an event that created a substantial threat of a marine casualty; “De-identified” – removing information that could identify people or entities.
