Water data are for incidents involving packaged materials only and do not include incidents where the vessel is the container (e.g., a barge or oil tanker).
In previous years, carriers were exclusively responsible for reporting hazardous materials release incidents. In 2005, Pipeline and Hazardous Materials Safety Administration (PHMSA) expanded the reporting requirements to include: reports by person(s) in physical possession of a hazardous material at the time an incident occurs during transport; reports on nonrelease incidents such as structural damage to cargo tanks specified for 1,000 gallons or more and undeclared shipments of hazardous materials.
