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.
