EPA Toxic Release Inventory (TRI) Search - Chemical Pollution & Facility Data

Search the EPA Toxic Release Inventory (TRI) for chemical pollution data reported by industrial facilities. Find facilities by state, ZIP code, facility name, or chemical. Get air emissions, water discharges, land disposal, underground injection, and off-site chemical transfers — with parent company names, EPA registry IDs, and open/closed status. Covers 25,000+ reporting facilities, 650+ chemicals, and data back to 1987.

Data is sourced from the EPA Envirofacts public API. No API key required.

Use Cases

• ESG research and sustainability reporting — Identify facilities emitting specific chemicals, quantify release volumes, and assess environmental risk by geography or parent company.
• Environmental due diligence — Screen industrial sites or neighboring parcels before real estate acquisition, lending, or investment.
• Regulatory and legal research — Pull historical release records for a facility or chemical as part of litigation support or regulatory compliance review.
• Investigative journalism — Identify the largest polluters in a state or ZIP code, track trends over time, or expose parent companies behind facility operations.
• Community and public health analysis — Assess chemical exposures in a specific ZIP code or county and identify facility clusters near residential areas.
• Supply chain sustainability auditing — Verify whether suppliers are among TRI reporters and assess the scale and type of their chemical releases.

FAQ

Does this require an EPA API key? No. The EPA Envirofacts API is public and requires no authentication.

How far back does TRI data go? TRI reporting began in 1987. Set year to any year from 1987 onward, or set it to 0 to retrieve all available years for a facility.

What chemicals are covered? The TRI program covers 650+ chemicals and chemical categories that meet EPA toxicity thresholds. This includes common industrial chemicals such as ammonia, benzene, lead, mercury, sulfuric acid, and many others.

What industries are required to report? Manufacturing, mining, electric utilities, hazardous waste treatment, and certain other industries with 10+ employees that use TRI chemicals above reporting thresholds must file annual TRI reports.

What is the difference between air, water, and land releases? The TRI categorizes releases by environmental medium: fugitive air emissions (uncontrolled), stack air emissions (through a smokestack), surface water discharges, underground injection, on-site land disposal, and off-site transfers to treatment or disposal facilities.
