Q

Which method requires prior approval to be used when cleaning up an oil spill?

🔍 Key Concepts

• Use of chemical dispersants and cleaning agents under U.S. oil spill response regulations • Difference between mechanical recovery methods (booms, skimmers, suction) and chemical methods • Role of the Federal On-Scene Coordinator (FOSC) and pre‑approval plans for spill countermeasures

💭 Think About

• Which option involves adding something new to the environment, rather than simply collecting or containing the spilled oil? • Think about which method might affect marine life or water quality the most, and therefore be more tightly controlled by regulators. • Under spill response plans, which technique usually needs specific authorization from the FOSC or to be listed on a pre‑approved schedule before use?

✅ Before You Answer

• Identify which choices are mechanical recovery devices versus a chemical treatment. • Recall that EPA and USCG policies restrict the use of certain dispersants and agents unless pre‑approved or specifically authorized. • Confirm which option, if misused, could cause additional environmental harm and so would logically require prior approval.
