What regulation outlines safeguarding measures for marine environments since 1950?

The regulation that outlines safeguarding measures for marine environments since 1950 is found in 33 CFR Part 6. This part specifically addresses the security of ports and waterways, emphasizing the importance of protecting marine environments from various potential threats. The regulation incorporates measures to prevent and respond to potential hazards and ensures that safety protocols are in place for the preservation of these vital ecosystems.

The historical significance of 33 CFR Part 6 is particularly important, as it has evolved to address the changing landscape of maritime security and environmental protection since its inception. It establishes the framework for the U.S. Coast Guard and other agencies to implement safeguarding strategies that contribute to the overall resilience and integrity of marine environments.

While other options such as 46 U.S.C 70116 and 50 U.S.C 191 pertain to maritime law and national security, they do not specifically detail the safeguarding of marine environments in the same manner as 33 CFR Part 6. The Coast Guard Security Regulation, while relevant to maritime security, does not encompass the broader environmental safeguarding measures established in 33 CFR Part 6. This makes the latter the correct reference for safeguarding marine environments in this context.
