This page indexes every EPA Toxics Release Inventory (TRI) facility in the PlainEnviro database whose facility name begins with the letter "O". TRI facilities are industrial sites required to disclose releases of listed toxic chemicals under EPCRA Section 313, and each one is assigned a unique EPA Facility Registry Service identifier for cross-system tracking.
The alphabetical index shows 605 facilities starting with "O", distributed across all 50 U.S. states and territories. The current view displays records 451–500 of 605, sorted by facility name. The largest disclosure in this letter group within the current sort is OWENS CORNING at 47.2 lbs across 3 chemicals.
Release figures are annual, self-reported estimates filed directly to the EPA under federal community right-to-know requirements and cover air, water, land, and off-site-transfer pathways. Every pound counts equally in the total regardless of chemical toxicity, so totals should not be read as a direct hazard ranking.
