The Enforcement and Compliance History Online (ECHO) system incorporates data from the ICIS-NPDES information management system maintained by the Office of Compliance to track permit compliance and enforcement status of facilities regulated by the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA). ICIS-NPDES is designed to support the NPDES program at the state, regional, and national levels. Active facilities are those currently in operation. Major/federally-reportable are facilities for which states must submit compliance and enforcement data to EPA. Under the Clean Water Act, a major facility is any NPDES facility or activity classified as such by the regional administrator, or in the case of approved state programs, the regional administrator in conjunction with the state director. Major municipal dischargers include all facilities with design flows of greater than one million gallons per day and facilities with EPA/state approved industrial pretreatment programs. Major industrial facilities are determined based on specific ratings criteria developed by EPA/state. Minor/not federally-reportable are facilities for which states are not required to submit data to EPA. EPA is therefore not able to verify the accuracy or comparability of data for these permits, although the Agency tracks their names and locations and may have some data about their inspections and enforcement activity.

Geospatial dataset of facilities containing positional information (latitude and longitude values) regulated by ICIS-NPDES that is maintained and updated monthly by the Facility Registry Service (FRS). The National Pollutant Discharge Elimination System (NPDES) module of the Integrated Compliance Information System (ICIS). Under NPDES, all facilities that discharge pollutants from any point source into waters of the United States are required to obtain a permit. The permit will likely contain limits on what can be discharged, impose monitoring and reporting requirements, and include other provisions to ensure that the discharge does not adversely affect water quality.

ECHO, Enforcement and Compliance History Online, is a web tool developed and maintained by EPA's Office of Enforcement and Compliance Assurance for public use. The ECHO website provides environmental regulatory compliance and enforcement information. The ECHO website includes environmental permit, inspection, violation, enforcement action, and penalty information about EPA-regulated facilities. This facility information generally covers four major environmental statutes over the past five years and includes Clean Water Act (CWA) facilities with direct discharge permits, under the National Pollutant Discharge Elimination System. Additional EPA environmental data sets are also available to provide additional context for analyses, such as Discharge Monitoring Report data from the ICIS-NPDES program. The Enforcement and Compliance History Online (ECHO) system incorporates Discharge Monitoring Report (DMR) data submitted by NPDES permit holders to the states or directly to EPA via the US EPA Central Data Exchange (CDX). This compendium of DMR data identifies the permit conditions or limits for each water discharge location, the actual values, identified by the permittee, for each monitored pollutant that was discharged, and whether or not the amounts discharged exceeded the permit limits. DMR data are stored in the EPA Office of Enforcement Compliance Assurance, Integrated Compliance Information System (ICIS), where it is extracted by ECHO.
