🔍 Key Concepts

• CFR Titles and Subjects – Title 33 generally covers navigation and waterways; Title 46 generally covers shipping and vessel inspection. • Ballast Water Management – regulations about controlling discharges from ships to prevent invasive species and pollution. • CFR Parts within a Title – each Part groups related topics (e.g., environmental protection vs. equipment design).

💭 Think About

• Which CFR Title would you expect to cover environmental protection of U.S. waters, including discharges from vessels? • Within that Title, which Part number is commonly associated with pollution prevention and environmental control from ships? • Looking at the other options, which Parts sound more like they deal with anchorage areas, vessel operations, or engineering systems, rather than environmental ballast water rules?

✅ Before You Answer

• Confirm which CFR Title (33 vs. 46) is focused on navigation, waterways, and environmental protection of U.S. waters. • Check which CFR Part under that Title is tied to pollution and environmental control from ships, including ballast water. • Eliminate choices whose Part descriptions clearly relate to anchorage regulations, vessel safety operations, or piping/engineering systems, not environmental ballast water management.
