From where does PWCS authority and jurisdiction derive?

The authority and jurisdiction of Port and Waterways Safety (PWCS) derive primarily from Title 14 of the United States Code, which addresses the Coast Guard's roles and responsibilities in maritime safety and security. This title grants the Coast Guard the authority to enforce laws and regulations related to navigable waters in the United States, ensuring safe and secure maritime operations.

PWCS is specifically designed to protect ports and waterways from various threats, including terrorism and environmental hazards. With this authority, the Coast Guard can implement safety measures, control vessel traffic, and manage port operations. This Title is central to the Coast Guard's mission to safeguard maritime interests.

In contrast, Title 10 primarily covers the armed forces and not directly related to maritime safety under the Coast Guard. Title 33 deals with navigation and navigable waters but does not grant the same overarching jurisdiction as Title 14, while Title 7 primarily pertains to agriculture, which is unrelated to maritime enforcement.
