US Steel Corp appears in the EPA Toxics Release Inventory as the parent or reported corporate owner of 18 individual facilities filing Form R disclosures under EPCRA Section 313. Operations span 9 states, and across all sites the company has disclosed a cumulative release total of 135.7M lbs.
The aggregated chemical footprint covers 213 distinct substances, of which 20 carry a carcinogen classification in the EPA Toxics Release Inventory. The heaviest-reporting state by release volume is Indiana (3 facilities, 79.2M lbs), followed by Pennsylvania at 40.6M lbs. The single largest facility disclosure is USS GARY WORKS in IN at 77.4M lbs.
Parent-company aggregation uses the company name as reported by each facility on its annual TRI filing; mergers, divestitures, or reporting variations across subsidiaries can produce inconsistent attribution year over year. All values are self-reported estimates under federal community right-to-know law and are not weighted by toxicity. Inclusion in the TRI does not establish a health risk to the public, it documents the regulatory disclosure record.
