14 USC 99 provides the primary authority for issuing COTP orders regarding vessel and facility security.

• A. 14 USC 99
• B. Magnuson Act
• C. 33 CFR Part 6
• D. MARSEC I

Answer: (A)

The key idea is that the Captain of the Port (COTP) derives the power to issue vessel and facility security orders from the Coast Guard’s statutory authority. Specifically, 14 U.S.C. § 99 grants the Coast Guard the authority to regulate and enforce safety and security measures for vessels and facilities in ports and waterways, which includes issuing orders to protect security. This statutory grant is the lawful basis for COTP actions like imposing security zones, restricting vessel movements, or mandating security measures during threats or incidents.

The other options don’t provide that authority in the same way: the Magnuson Act relates to fisheries management, not port or vessel security; 33 CFR Part 6 deals with information release procedures rather than the authority to issue security orders; and MARSEC levels outline security posture within the maritime security framework but do not themselves grant the power to issue COTP orders.
