This GIS dataset contains points depicting U.S. EPA Superfund features. This dataset is reserved for important Superfund site features that are best captured as point features in geospatial datasets. 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.

This GIS dataset contains polygons depicting U.S. EPA Superfund Site boundaries. Site boundaries are polygons representing the footprint of a whole site, defined for purposes of this effort as the sum of all of the Operable Units and the current understanding of the full extent of contamination. For Federal Facility sites, the total site polygon may be the Facility boundary. As site investigation and remediation progress, OUs may be added, modified or refined, and the total site polygon should be updated accordingly.

Point locations for sites in EPA Region 6 which are documented as being part of the National Priorities List as of 3/31/2023. The locations were determined by EPA Region 6 Superfund RPMs and/or site HRS Documentation reports. EPA Region 6 includes AR, LA, NM, OK, TX.

This GIS dataset contains polygons depicting U.S. EPA Superfund Operable Unit boundaries. The operable unit (OU) polygons represent an individual OU’s perimeters, which are used to identify a portion of a Superfund site with which assessment and response actions are associated. CERCLA regulations (40 C.F.R. § 307.14) define an OU as a “discrete portion of a remedial response [that] manages migration, or eliminates or mitigates a release, threat of release, or pathway of exposure. The cleanup of a site can be divided into a number of operable units . . . [that] may address geographical portions of a site.” Determined on a site-specific basis, OUs may represent distinct geographic areas, media or releases. Note that OUs may overlap geographically when representing distinct media or areas of concern. OU boundaries become the building blocks of site boundaries.

This data layer provides access to Superfund National Priority List Sites as part of the CIMC web service. Superfund is a program administered by the EPA to locate, investigate, and clean up worst hazardous waste sites throughout the United States. EPA administers the Superfund program in cooperation with individual states and tribal governments. These sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills - the key word here being abandoned. Only NPL sites have been included in Cleanups in My Community thus far. EPA maintains the NPL, which identifies for the States and the public those sites or other releases that appear to warrant remedial (long term) actions. These NPL sites fall into the following categories: Proposed: Sites may be proposed for the NPL and then may be placed on the NPL as final or be removed from the Proposed NPL. Final: Those sites placed on the NPL are called "final," and for these sites, a cleanup remedy is selected and implemented. However, it may be several years after construction of the remedy is completed before the hazardous substances are completely cleaned up or controlled in place. Deleted: After the clean up process is complete, and appropriate reviews confirm the area is cleaned up or the hazards are controlled, sites can be deleted from the NPL. For more information on the data provided through this web service, please see the processing steps below, and see more information here: https://www.epa.gov/cleanups/cimc-about-data#superfund. The CIMC web service was initially published in 2013, but the data are updated twice a month.
