MARPOL 73/78 (International Convention for the Prevention of Pollution from Ships) is the main international treaty addressing vessel-source pollution including oil, chemicals, sewage, and garbage.

Correct answer: $3,000 per gross ton or $22 million, whichever is greater (for vessels over 3,000 gross tons)
OPA 90 sets liability limits based on vessel type and gross tonnage, with limits periodically adjusted by regulation; tank vessels face higher limits than non-tank vessels.
