Evaluation of Risks to Federal Facility Superfund Site Remedies from Wildfires

According to the EPA, 13 million people live within three miles of a federal facility Superfund site. It is important that the EPA understand when cleanup remedies at these sites may be threatened. If the remedies fail or are otherwise impaired, contaminants may be released into the surrounding communities, and the federal funds expended to implement the remedies may be wasted. To that end, the EPA OIG is issuing a limited series of reviews to help identify any such threats. This is the third report in that series. The first, which addresses sea-level rise and storm surge risks, was issued in June 2025. We issued the second, which addresses inland flooding risks, simultaneously with this report, which addresses wildfire risks.

ASTSWMO Risk Mitigation Practices Fact Sheet

Risk mitigation practices (RMP) at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) federal facility sites are critical for addressing environmental contamination efficiently and responsibly. These practices involve measures to mitigate risks posed by hazardous substances while long-term remediation plans are developed and implemented. Some examples discussed include access restrictions, interim land use controls, dig notifications, and public awareness. The purpose of this Fact Sheet is to help regulators identify when RMP should be considered to mitigate environmental impacts and to identify potential existing resources available. This Fact Sheet recommends regulators consider RMP at all federal facility CERCLA sites where such practices will reduce risk, prevent the continued migration of contamination, be cost effective, and help build community trust. The …

ASTSWMO Dispute Resolution Fact Sheet

Dispute resolution (DR) is a process used to resolve disagreements between parties, which can be either a formal or informal process. This fact sheet is an informational tool designed to help States navigate the dispute process and find ways to resolve disagreements between a Responsible Party and State regulators before submitting a formal dispute resolution.

EPA-Comparing RCRA and CERCLA

The U.S. Environmental Protection Agency (EPA) is working to ensure that contamination from the former DuPont East Chicago facility at 5215 Kennedy Avenue in East Chicago is properly addressed and that people living in the community are protected, informed and involved in the cleanup process. EPA’s authority to compel cleanup of contamination at the former DuPont facility is derived from the Resource Conservation & Recovery Act (RCRA). When RCRA and Superfund, also known as the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA) are related, EPA coordinates the two cleanup programs to eliminate duplication of effort and streamline cleanup processes. EPA encourages close coordination among RCRA and Superfund cleanup programs.
