The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, requires responsible parties to clean up and remediate contaminated sites. Many states have similar local requirements. In the 35 years since the law was passed, there has been much discussion of reforming CERCLA, but has anything yet changed, and how might it change under the new presidential administration? On October 12, 2017, ELI convened a panel in Newark, New Jersey, to discuss these questions, current regulatory developments, and approaches to working with regulatory agencies on site cleanup issues. In this Dialogue, ELR presents a transcript of the panel, which has been edited for style, clarity, and space considerations.
