The Coast Guard proposes to increase the limits of liability for vessels, deepwater ports, and onshore facilities, under the Oil Pollution Act of 1990, as amended (OPA'90), to reflect significant increases in the Consumer Price Index (CPI). We also propose a simplified regulatory procedure for the Coast Guard to make future required periodic CPI increases to the OPA'90 limits of liability for vessels, deepwater ports, and onshore facilities. These regulatory inflation increases to the limits of liability are required by OPA'90, and are necessary to preserve the deterrent effect and "polluter pays" principle embodied in OPA'90. Finally, we propose language to clarify applicability of the OPA'90 vessel limits of liability to two categories of tank vessels, edible oil cargo tank vessels and tank vessels designated as oil spill response vessels. This clarification to the existing regulatory text is needed for consistency with OPA'90. This project supports the Coast Guard's strategic goals of maritime stewardship and maritime safety.
