The use of sinking and dispersing chemical agents for removal of surface oil is __________.

🔍 Key Concepts

• Federal On-Scene Coordinator (FOSC) authority during an oil spill response • Environmental impact of chemical agents that sink or disperse oil • Typical/most common methods of oil spill response used in U.S. waters

💭 Think About

• Ask yourself: In U.S. law, are chemicals that intentionally sink or disperse oil treated as routine tools, or as special tools needing tight control? • Consider which answer choices sound like general statements about cost or frequency of use, versus those that describe a regulatory approval requirement. • Think about what methods you most often hear about in U.S. spill response: booming, skimming, burning, shoreline cleanup, or sinking/dispersing chemicals?

✅ Before You Answer

• Verify whether the FOSC must approve certain countermeasures before they are used on a spill. • Check if U.S. policy tends to assume that chemical dispersants are automatically safe for sea life or if they are treated cautiously. • Confirm whether sinking/dispersing chemicals are actually the most common method used in the U.S., or if other mechanical/physical methods are more typical.
