The Oil Pollution Act of 1990 (OPA 90) is a federal law in the United States that governs oil spill response and liability. Part of OPA 90 requires regulated facilities, such as oil terminals and pipelines, to have a spill response plan in place that outlines the steps to be taken in the event of an oil spill. This plan should include information on the equipment and resources available for response, the roles and responsibilities of personnel, and procedures for reporting spills to the relevant authorities. The purpose of having a spill response plan is to ensure that spills are contained and cleaned up quickly, minimizing the impact on the environment and communities. The development of a spill response plan is a crucial component of the overall effort to prevent and mitigate the effects of oil spills in the U.S.
