Pursuant to a congressional request, GAO reviewed the Environmental Protection Agency's (EPA) completed Superfund hazardous waste cleanup actions, focusing on the: (1) type and extent of actions taken at those sites; and (2) challenges EPA will face in managing and monitoring these sites.
Recommendations for Executive Action
|Environmental Protection Agency||1. To more accurately reflect the extent to which cleanup levels have been achieved at Superfund sites, the Administrator, EPA, should modify the classification of construction-complete and deleted sites to identify sites according to whether they have achieved their objectives of protecting human health and the environment and have been deleted or are awaiting deletion from the National Priorities List, required no removal or remedial action, or will require long-term efforts to achieve their cleanup objectives.|
|Environmental Protection Agency||2. To address the challenges of increasing resource demands to clean up Superfund sites and plan for potential resource requirements at the federal and state level, the Administrator, EPA, should conduct additional studies to estimate the long-term cost to EPA of monitoring and inspecting construction-complete and deleted sites and the cost to states of operating and maintaining these sites.|
