Published by U.S. EPA Office of Environmental Information (OEI) | U.S. Environmental Protection Agency | Catalog Last Checked: May 18, 2026 at 06:36 AM | Dataset Last Updated: January 09, 2020 at 12:00 AM
This web feature service contains location and facility identification information from EPA's Facility Registry Service (FRS) for the subset of facilities that link to the Emission Inventory System (EIS). The Emission Inventory System (EIS) maintains an inventory of large stationary sources and voluntarily-reported smaller sources of air point pollution emitters. It contains information about facility sites and their physical location, emission units, emission processes, release points, control approaches, and regulations. Facility inventory data are kept separate from the emissions data and have stable identifiers to improve continuity from year to year and to help identify duplicate or missing facilities. FRS identifies and geospatially locates facilities, sites or places subject to environmental regulations or of environmental interest. Using vigorous verification and data management procedures, FRS integrates facility data from EPA's national program systems, other federal agencies, and State and tribal master facility records and provides EPA with a centrally managed, single source of comprehensive and authoritative information on facilities. Additional information on FRS is available at the EPA website https://www.epa.gov/enviro/facility-registry-service-frs
