Which facilities report toxic chemical releases?
Which facilities report toxic chemical releases? Search the EPA Toxics Release Inventory (TRI Basic Data) by facility or parent company, state, chemical, CAS number, NAICS, reporting year, chemical class (carcinogen, PBT, PFAS), or minimum release amount. Returns the facility (entity-resolved where possible), parent company, chemical, and on/off-site release totals — the emissions universe for environmental, remediation, and EHS sellers. EPA public-domain; amounts self-reported.
