A bill to amend the Oil Pollution Act of 1990 to equalize the limit on the liability for oil tankers and cargo vessels and to provide for the investment of amounts in the Damage Assessment Restoration Revolving Fund.

Amends the Oil Pollution Act of 1990 to limit the liability for damages resulting from the discharge of oil into U.S. navigable waters or the exclusive economic zone by a cargo vessel to the same extent as such damages are limited for tank vessels. Requires the Secretary of the Treasury to invest amounts deposited into the Damage Assessment and Restoration Revolving Fund in interest bearing U.S. obligations and to deposit the earned interest in such Fund.
