Facility Search Types

ECHO Facility Searches query a database of hundreds of thousands of facility records. There are five primary facility search types available, each of which provides tailored search options and corresponding results based on how facilities are regulated under the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act for hazardous waste, and Safe Drinking Water Act. In addition, results returned for the facility search include federal enforcement actions taken under the relevant statute which are tracked in EPA's ICIS database. Read About the Data to learn about the data included in ECHO.

All Data

The All Data search is selected by default. The All Data option is the most general search and searches across all of the records based on your selections.

Air

The Air search captures data on stationary sources regulated under the Clean Air Act (CAA) and reported to several EPA air emission inventory programs:  National Emissions Inventory, Greenhouse Gas Reporting ProgramToxic Release Inventory, and Clean Air Markets Division Acid Rain Program and Clean Air Interstate RuleThe results reflect data drawn from the ICIS-Air database and other air emissions inventory data systems.

Water

The Water search captures data on facilities regulated under the Clean Water Act (CWA) and managed under the National Pollutant Discharge Elimination System (NPDES) program. The results displayed reflect data drawn from the ICIS-NPDES database.

NPDES Program Areas
The Industrial Stormwater search captures data on facilities managed under the NPDES Industrial Stormwater program area. The results displayed reflect data drawn from the ICIS-NPDES database.

The Biosolids search captures data on facilities managed under the NPDES Biosolids program area. The results displayed reflect data drawn from the ICIS-NPDES database. The universe of facilities on ECHO includes NPDES IDs that have a biosolids permit component, an "L" as the third character of the NPDES ID, a biosolids violation, a biosolids inspection, a biosolids enforcement action, or submitted a Biosolids Annual Report electronically through NeT.

Hazardous Waste

The Hazardous Waste search captures data on hazardous waste handlers regulated under the Resource Conservation and Recovery Act (RCRA) Subtitle C Hazardous Waste Program. The results displayed reflect data drawn from the RCRAInfo database. The RCRAInfo system allows tracking of many types of information about the regulated universe of RCRA hazardous waste handlers. RCRAInfo characterizes facility status, regulated activities, and compliance histories and captures detailed data on the generation of hazardous waste from large quantity generators and on waste management practices from treatment, storage, and disposal facilities.

Drinking Water

The Drinking Water search captures data on public drinking water systems regulated under the Safe Drinking Water Act (SDWA). The results displayed for each of the systems returned reflect data drawn from the federal version of the Safe Drinking Water Information System (SDWIS/Fed).
 
Under SDWA, most states and the Navajo Nation have "primacy," meaning the authority to implement and enforce SDWA within their jurisdictions if they can show that their standards will be at least as stringent as the national standards. They also must ensure that public water systems meet these standards. States with primacy collect detailed system and monitoring data from systems within their jurisdictions, and submit a portion of that data quarterly to EPA. The data required to be reported to EPA include information about each system, such as its name, type (community, transient, non-transient), population served, source water type, violations of SDWA regulations, and enforcement actions taken to return the system to compliance.
 
The information presented is submitted by public water systems to their state environmental agencies, who submit the data to EPA. States often have more detail in their data systems than are reported to EPA. For example, in some cases, states may report to EPA that a violation occurred, but not the magnitude of the violation. For more comprehensive data or measured values, please contact your state drinking water program.
