How to look up EPA-regulated facilities near any address

The Environmental Protection Agency's Enforcement and Compliance History Online database — usually just called ECHO — tracks every facility in the United States regulated under a major environmental program. Anyone can query it for free. If you want to know what's near your address that emits air pollutants, discharges to water, handles hazardous waste, or is subject to environmental oversight, ECHO is the source.

This guide covers what ECHO tracks, how to interpret facility records, and how HomeStoop surfaces the most relevant results per property.

What ECHO covers

ECHO aggregates data from five major EPA programs:

Clean Air Act (CAA) regulates air emissions from industrial and non-industrial sources. Facilities regulated under CAA include manufacturing plants, dry cleaners, power plants, gas stations, and auto body shops.

Clean Water Act (CWA) regulates discharges to surface water. Facilities regulated under CWA operate under National Pollutant Discharge Elimination System (NPDES) permits. Includes wastewater treatment plants, industrial facilities that discharge process water, and many concentrated animal-feeding operations.

Resource Conservation and Recovery Act (RCRA) governs hazardous waste handling. Facilities regulated under RCRA generate, transport, treat, store, or dispose of hazardous waste. Includes chemical plants, hospitals, dry cleaners, printers, and manufacturing operations.

Safe Drinking Water Act (SDWA) regulates public water systems.

Toxic Substances Control Act / Toxic Release Inventory (TRI) requires facilities to report releases of specific toxic chemicals. TRI focuses on larger industrial operations.

A facility can be regulated under multiple programs at once. A large chemical plant might report under CAA, CWA, RCRA, and TRI simultaneously — each program covers different aspects of its operations.

What a facility record shows

For each regulated facility, ECHO publishes:

Facility name and address
Which programs the facility is regulated under
Current compliance status ("No Violation Identified" or a violation code)
Whether the facility is a Significant Noncomplier (SNC) under any program
Historical inspection dates and outcomes
Formal enforcement actions taken (fines, orders, injunctions)
Penalties paid to date

The most useful single field is current compliance status. If the facility is "in compliance," the EPA has no active concerns as of the most recent inspection. If it's in violation, there's an ongoing issue.

Interpreting compliance status

Not every violation is equal. The words to watch for:

"No Violation Identified." The facility passed its most recent inspection. Nothing to worry about.

"Violation" or "Noncompliance" (without "No"): Active violation. The facility is out of compliance with one or more permit conditions. This can range from minor paperwork issues to serious emissions events.

"Significant Noncomplier." The EPA's most serious classification. Reserved for facilities with the largest or most persistent violations. Only a small fraction of regulated facilities carry this designation. If a nearby facility is flagged SNC under any program, it's worth digging into what specifically they violated.

"High Priority Violation" (CAA specific). Similar to SNC for Clean Air Act violations. Indicates emissions or reporting violations serious enough for federal enforcement.

What most nearby facilities actually are

A common surprise when people first query ECHO for a residential address: dozens of facilities show up within a few miles. The overwhelming majority are:

Dry cleaners — regulated under CAA (perchloroethylene emissions) and often RCRA (waste handling)
Gas stations — CAA (fuel vapor emissions) and RCRA (fuel storage tank management)
Auto body shops — CAA (solvent emissions) and RCRA (hazardous waste)
Small manufacturing — usually CAA for anything involving heating, painting, or coating
Print shops — CAA (VOC solvents) and RCRA (waste inks)
Municipal wastewater treatment plants — CWA (NPDES permits)

None of these are inherently dangerous. Being regulated means the facility operates under an EPA-monitored permit and has to report its emissions and comply with limits. That's a good thing, not a bad thing. What you're looking for in ECHO is not "presence of facilities" but "facilities with violations that haven't been resolved."

When to actually be concerned

Rough guidance for interpreting an ECHO query around a residential address:

Nothing flagged. The regulated facilities in your area are complying with their permits. Move on.

Minor recent violations, resolved. Facilities occasionally trip a paperwork or reporting requirement. If the current status is back to "No Violation Identified," the issue is closed.

Active violations, ongoing. Worth reading the details. Sometimes an active violation means the facility is in the middle of a corrective action plan already agreed with the EPA — process, not danger. Other times it's an ongoing emissions concern.

Significant Noncomplier designation. This is where you should pay closer attention. Pull the full compliance report and look at what specifically triggered the SNC status. It might be an ongoing multi-million-dollar penalty case; it might also be a resolved historical issue that the classification hasn't updated on yet.

Multiple SNCs in close proximity. This is uncommon and usually indicates an environmental justice concern — the neighborhood has more polluting facilities than typical. Worth deeper research, including looking at local advocacy group reporting.

How HomeStoop shows EPA facilities

Every HomeStoop property page includes a "Regulated facilities within 3 miles" card. It shows up to 5 facilities, filtered to those under CAA, CWA, RCRA, or SDWA programs. Each row includes:

Facility name (linked to the EPA's full detailed facility report if a Registry ID is available)
Programs the facility is regulated under
A "current violation" or "significant violator" badge if applicable

The card cites the EPA ECHO facility registry directly. The data refreshes weekly.

If no regulated facilities exist within 3 miles, the card doesn't render — no data is better than fake data.

What to check next

If you want to dig deeper into a specific facility:

Look up the facility on ECHO's detailed facility report tool
Read the Enforcement Case Search for any cases involving that facility
If you're concerned about an environmental justice issue, check the EPA's EJScreen tool — it overlays demographic and environmental data at the block-group level

Federal environmental data is one of the most robust public-records datasets available. Use it early in any due diligence process — before you make an offer, not after.
