Superfund: EPA Should Take Additional Actions to Manage Risks from Climate Change, Report to Congressional Requesters [open pdf - 3MB]
From GAO [Government Accountability Office] Highlights: "Administered by EPA [Environmental Protection Agency], Superfund is the principal federal program for addressing sites containing hazardous substances. EPA lists some of the most seriously contaminated sites--most of which are nonfederal--on the NPL [National Priorities List] and has recorded over 500 contaminants, including arsenic and lead, at those sites. Climate change may make some natural disasters more frequent or more intense, which may damage NPL sites and potentially release contaminants, according to the Fourth National Climate Assessment. GAO was asked to review issues related to the impact of climate change on nonfederal NPL sites. This report examines, among other objectives, (1) what available federal data suggest about the number of nonfederal NPL sites that are located in areas that may be impacted by selected climate change effects and (2) the extent to which EPA has managed risks to human health and the environment from the potential impacts of climate change effects at such sites. GAO analyzed available federal data; reviewed laws, regulations, and documents; interviewed federal officials and stakeholders; visited three nonfederal NPL sites that experienced natural disasters; and compared EPA actions to manage risk to GAO's six essential elements of enterprise risk management."
