Sites with Potential Smelting-Related Operations (FOIA 1): This report includes sites that have smelting-related, or potentially smelting-related, indicators in the Superfund database, the Superfund Enterprise Management System (SEMS). The report includes information on the site location as well as contaminants of concern.

Completed RODs, ROD Amendments and ESDs (FOIA 2):  Displays completed Records of Decision (RODs), ROD Amendments, and Explanations of Differences (ESDs) for active and archived sites stored in SEMS.

All Proposed, Final and Deleted NPL Sites (FOIA 3, FOIA 4, FOIA 5): This dataset is comprised of sites proposed to be added to the NPL, sites on the NPL, and sites deleted from the NPL.

Lien on Property (FOIA 12): Displays Superfund lien on property activity, the lien property information, and the parties associated with the lien.

Active Site Inventory (List 8R Active): Displays site and location information at active sites in SEMS. An active site is one at which site assessment, removal, remedial, enforcement, cost recovery or oversight activities are being planned or conducted. NPL sites include latitude and longitude information. For non-NPL sites, a brief site status is provided.

Archived Site Inventory (List 8R Archived): Displays site and location information at archived sites. An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program.

Contaminant of Concern Data for Decision Documents by Media, FYs 1982-2014 (Final NPL, Deleted NPL, and Superfund Alternative Approach Sites): Displays contaminant of concern data for decision documents by environmental media. Includes data from fiscal years 1982-2014 for final and deleted NPL sites as well as sites with a Superfund Alternative Approach (SAA) agreement in place. NPL and SAA status is current as of Sept. 17, 2018.

Remedy Component Data for Decision Documents by Media, FYs 1982-2014 (Final NPL, Deleted NPL, and Superfund Alternative Approach Sites):  Displays remedy component data for decision documents by media. Includes data from fiscal years 1982-2014 for final and deleted NPL sites as well as sites with a Superfund Alternative Approach (SAA) agreement in place. NPL and SAA status is current as of Sept. 17, 2018.

Archived Data and Reports

CERCLIS was a Superfund data system that EPA decommissioned in 2014 following its deployment of the Superfund Enterprise Management System (SEMS). The datasets and reports in the table below draw upon the final CERCLIS dataset, which represents program progress as of the end of fiscal year 2013. Descriptions for these products can be found under the table.

CERCLIS (.dbf) and (.txt) Record Layout File: The record layout provides field names, character types, character positions and field lengths for the CERCLIS dBASEIII+ (.dbf) and CERCLIS ASCII Text (.txt) downloadable files.

NPL Sites and Non-NPL Sites (SCAP 12): Displays the sequence of activities undertaken at all sites in CERCLIS, both National Priorities List (NPL) sites and non-NPL sites. The SCAP 12 can be customized to contain only NPL sites or non-NPL sites, as specified in the order. NPL sites include sites proposed to the NPL, sites currently on the final NPL, and sites deleted from the final NPL. Non-NPL sites include sites removed from the proposed NPL, sites withdrawn from the final NPL, sites being addressed as part of another NPL site, and all other non-NPL sites. Where available, the report includes funding information for each action, as well as site characterization data.

CERCLIS dBASEIII+Format (.dbf): This file contains 55 dBASEIII+ (.dbf) files when decompressed. These files provide detailed information on hazardous waste sites, potential hazardous waste sites, and remedial activities across the nation. You will need a dBASEIII+ browser or program to read the files. You may also want to view the CERCLIS Record Layout to identify the named fields used.

CERCLIS ASCII Text Format (.txt): This file (cerctxt.zip), contains 55 ASCII (.txt) formatted files when decompressed. Combined these files provide detailed information on hazardous waste sites, potential hazardous waste sites, and remedial activities across the nation.

Contaminants at CERCLIS Sites (List 10): Lists contaminants recorded for Superfund sites, including the contaminant Chemical Abstract Service (CAS) number and maximum concentration level. Affected media and the cleanup action(s) associated with the contaminant are also included, as well as basic site information for the affected sites.

IC/EC in Remedy Decision Documents: This report contains data from official decision documents (e.g., Records of Decision (RODs), ROD Amendments, Explanation of Significant Differences) identifying institutional and/or engineering controls (IC/ECs) that are part of the selected remedy. This report does not indicate that the institutional and engineering controls are currently in place nor does it indicate that the ICs/ECs will be in place once the remedy is complete. It only indicates that the decision to include either of them in the remedy is documented as of the completed date of the document.
