Oil spill cleanup costs for a nation or region can be estimated by taking the average cost for the speci­fied region and multiplying it by various “modifi­cation factors” that are a function of oil type (light crude, heavy crude, No. 4 fuel, etc.), spill size (<34 tons, 34–340 tons, etc.), location type (off­shore, near-shore, in-port), cleanup method (disper­sants, burning, manual), and extent of shoreline oiling (0–1 km, 2–5 km, etc.). For an average cost of $23.02 per liter and modifiers for a region in the United States of 1.32, 0.65, 1.28, 0.25, and 1.53 for oil type, spill size, location type, cleanup method, and extent of shoreline oiling, respectively, deter­mine the estimated cleanup cost per liter of an oil spill in the region of the United States.
