NPL Superfund Institutional Control Boundaries (EPA)

Published by U.S. EPA Office of Environmental Information (OEI) | U.S. Environmental Protection Agency | Catalog Last Checked: May 26, 2026 at 04:13 PM | Dataset Last Updated: March 06, 2018 at 12:00 AM
This GIS dataset contains polygons depicting U.S. EPA Superfund Institutional Control boundaries. Institutional controls are non-engineered instruments, such as administrative and legal controls, that help to minimize the potential for exposure to contamination and/or protect the integrity of a response action. ICs typically are designed to work by limiting land and/or resource use or by providing information that helps modify or guide human behavior at a site. Superfund features are managed by regional teams of geospatial professionals and remedial program managers (RPMs), and SEGS harvests regional data on a weekly basis to refresh the national dataset and feature services.
