Who oversees the cleanup of sites under CERCLA?

The cleanup of sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, is primarily overseen by the Environmental Protection Agency (EPA). The EPA is responsible for evaluating potential hazardous waste sites, determining the need for cleanup, and implementing the necessary remediation efforts. This includes conducting risk assessments, overseeing the investigation and cleanup process, and ensuring that corrective actions are taken to protect public health and the environment. The EPA has a significant role in coordinating cleanup efforts with state agencies, responsible parties, and other stakeholders to ensure compliance with federal regulations and safeguard communities.

The other agencies mentioned, such as the Department of Energy, the Department of Agriculture, and the Department of Justice, have distinct roles that do not focus on managing hazardous waste site cleanups under CERCLA. While they may support related initiatives or collaborate in certain contexts, the direct authority and responsibility for CERCLA site cleanups rest with the EPA.
